III. y` DRAFT ENVIRONMENTAL IMPACT STATEMENT SUMMARY ABOUT THE PIEDMONT TRIAD INTERNATIONAL AIRPORT DENS The Federal Aviation Administration (FAA) prepared this Draft Environmental Impact Statement (DEIS) to identify the potential environmental effects associated with the construction and operation of proposed improvements to the Piedmont Triad International Airport (PTIA). The Piedmont Triad Airport Authority (PTAA), the owner and operator of PTIA, completed the 1994 Master Plan Update (MPU) that identified a comprehensive development program for the expansion of PTIA. (PTAA is in the process of completing a new MPU update that does not affect the current proposal for improvements to PTIA). In April 1998, the PTAA submitted the new runway portion of its Airport Layout Plan (ALP) to the FAA for environmental approval in connection with its intent to seek Federal funds for Master Plan project implementation. The FAA must prepare an EIS and issue a Record of Decision (ROD) that reflect its approval or disapproval of the proposal under environmental criteria. The proposed improvements cannot be considered eligible for Federal funding until the FAA issues a ROD. THE PROPOSED IMPROVEMENTS TO PTIA The PTAA is requesting airside and landside improvements to PTIA on the ALP that are intended to enable the airport to effectively meet estimated levels of activity associated with the operational requirements of a proposed air cargo hub. The PTAA's proposed project features a new parallel Transport Category runway, 9,000 feet long by 150 feet wide, which would be located on the western side of the airport. This runway is intended to improve airfield capacity during both visual meteorological conditions (VMC) and instrument meteorological conditions (IMC). The proposed project also includes the development of an overnight, express air cargo sorting and distribution facility, roadway improvements, NAVAIDS for new Runway 5U23R, property acquisition and relocation of several airport tenant operations (see Figure S-1). FAA's ENVIRONMENTAL RESPONSIBILITIES In recognizing the importance of protecting the environment, the U.S. Congress passed the National Environmental Policy Act of 1969 (NEPA) to encourage Federal agencies to enhance the environment. NEPA requires Federal agencies to treat environmental impact as a primary criterion in evaluating a proposed project. It also requires Federal agencies to analyze and consider alternatives to, and the environmental impacts of, their proposed actions, to disclose and consider mitigation for those impacts, and to provide interested parties with an opportunity to participate in the environmental review process. In addition, Federal agencies must consider the "No-Action" Alternative. Furthermore, NEPA requires Federal agencies to consider a proposed action's environmental consequences along with the agency's statutory mission and technical factors related to their areas of expertise. The FAA is responsible for complying with NEPA whenever an airport sponsor seeks to implement projects depicted on an ALP and associated Federal actions. The FAA has reviewed PTIA's 1994 ALP W:\PIEDMON7\DEIS\Exsum\fnl_exs.doc\03/23/00 S-1 Summary and determined that an EIS would be the most appropriate document for the agency to fulfill its obligations under NEPA and FAA Orders 1050.1D (FAA, 1986) and 5050.4A (FAA, 1985). In July 1998, the FAA published a Notice of Intent (NOI) to prepare the DEIS for the PTIA proposed expansion. Public and agency Scoping meetings were held in August 1998 to receive comments regarding the scope of the analysis and identify any potential environmental impacts. In addition, a Public Information Workshop was held in April 1999 to receive any additional comments from interested parties on the scope of the analysis to be conducted during the environmental process. In Chapter 2.0, Purpose and Need, the purpose and need for the proposed project is explained and defined. In Chapter 3.0, Alternatives, the FAA presents and analyzes a range of alternatives, including the No-Action Alternative and the PTAA's proposed project, and focuses on reasonable alternatives to the proposed project, as prescribed by the Council on Environmental Quality (CEQ) regulations. Chapter 3.0, Alternatives also includes a comparison of these alternatives and a summary of their environmental and socioeconomic effects, so that the differences between them are clear. COOPERATING AGENCY A cooperating agency is an agency that has jurisdiction by law or special expertise regarding any environmental impact resulting from a proposed project or reasonable alternative. The Federal Highway Administration (FHWA) has been invited and has agreed to participate as a cooperating agency for this DEIS, because PTAA is proposing several roadway projects in its development program that would be needed if the PTAA proposed runway and associated projects were implemented. These projects would include construction of a tunnel for Bryan Boulevard under the proposed new parallel Runway 5U23R and construction of two bridges over Bryan Boulevard for the cross-field taxiways. For NEPA analysis in this DEIS, PTAA's proposed improvement plan as well as its alternatives include these surface transportation projects. These surface transportation improvement projects are under the jurisdiction of the FHWA and the North Carolina Department of Transportation (NCDOT). This DEIS contains a special technical appendix (Appendix 1) that presents separate FHWA Purpose and Need statements, Alternatives evaluation, and Environmental Consequences (impact analysis) for the surface transportation improvements. The FHWA has proposed to adopt the FAA's Final Environmental Impact Statement (FEIS) and ROD, in compliance with NEPA requirements. Specific elements of the FHWA approval actions include: • FHWA approval of the Surface Transportation developments which would include interchange and arterial roadway improvements to provide increased capacity, Level of Service and safety as well as improve system linkage within the area surrounding PTIA, and • FHWA Federal environmental approval necessary to proceed with the processing of an application for Federal funding for those development proposals qualifying under 42 USC 433(2)(c) and 23 CFR 771. W:\PIEDMONl1DEIS\Exsum\fnl exs.doc\03/23/00 S-2 Summary In addition to the above described proposed surface transportation improvement projects, the PTAA is undertaking several additional roadway improvement projects which would be implemented by the PTAA whether or not proposed Runway 5L/23R and the air cargo sorting and distribution facility were developed. These independent projects include the closure and relocation of a portion of Regional Road, a new interchange at Bryan Boulevard and Old Oak Ridge Road, the relocation of a portion of Old Oak Ridge Road, reconstruction of South Triad Boulevard and construction of a new North Triad Boulevard interchange. These independent roadway improvement projects are also under the jurisdiction of the FHWA and NCDOT. This DEIS discloses the potential environmental impacts associated with these projects and the potential cumulative environmental impacts that may occur. However, these projects, unlike the roadway projects described in the previous paragraph, are independent of the new runway proposal and are therefore also included in the analysis of the No-Action Alternative. The FHWA proposes to adopt the FAA's FEIS and ROD for these projects as well. DOCUMENT ORGANIZATION The format and content of the DEIS conform to the Federal requirements for an EIS in the regulations and guidelines that implement the procedural provisions of the National Environmental Policy Act of 1969 (NEPA). The DEIS is composed of two volumes: • Volume 1 - DEIS Documentation - contains the text of analysis and associated tables and exhibits of the DEIS. • Volumes 2 and 3 - Technical Appendices - contains various appendices to the DEIS related to technical information, coordination, and other reference materials. PURPOSE AND NEED FOR THE PROPOSED IMPROVEMENTS The PTAA has been approached by an overnight, express air cargo operator (FedEx) which, after a detailed evaluation of potential locations, has selected PTIA as the site for establishment of a new hub to sere its eastern United States market. PTAA, in turn, wishes to develop an air cargo hub at PTIA, and has requested that the FAA take the necessary Federal actions to implement the proposed development of a parallel runway and associated projects at PTIA. One of the missions of the PTAA is to support the growth and development of PTIA such that the airport is capable of accommodating the air transportation needs of the Triad. It is also a mission of the PTAA to continue to allow PTIA to be a major employment center and economic generator in the Triad. Development of an overnight air cargo hub at PTIA would facilitate PTAA's meeting their stated mission. Likewise, the FAA has a statutory authority to both support and promote national transportation policies, and to respond to project-specific needs for aviation development. The immediate action required of the FAA is the processing of a draft and final EIS, and the issuance of an environmental finding in a ROD. W:\PIEDMONT\DEIS\Exsum\fnl exs.doc\03/23/00 S-3 Summary CONSISTENCY WITH FEDERAL TRANSPORTATION POLICIES The FAA is charged with the implementation of Federal policies under its statutory authorities. The National Transportation Policy was established by §502(b) of the 1990 amendments to the Airport and Airway Improvement Act of 1982 and is codified at 49 U.S.C. § 47101(b). It is within the framework of NEPA and the Airport and Airway Improvement Act, as amended, that the FAA is responding to the PTAA's proposal. The language of 49 U.S.C. § 40101(b) further directs the Secretary of Transportation to consider the following to be in the public interest in regard to air cargo transportation: (1) Encouraging and developing an expedited all-cargo air transportation system provided by private enterprise and responsive to: (A) The present and future needs of shippers; (B) The commerce of the United States; (C) The national defense. (2) Encouraging and developing an integrated transportation system relying on competitive market forces to decide the extent, variety, quality, and price of services provided. (3) Providing services without unreasonable discrimination, unfair or deceptive practices, or predatory pricing. The potential development of an overnight, express air cargo hub at PTIA is consistent with FAA's responsibility to support locally sponsored projects that fulfill the above referenced public policy objectives. DEVELOP AN AIR CARGO SORTING AND DISTRIBUTION FACILITY Demand for the air cargo hub at PTIA is driven by existing and projected demand for express overnight air cargo movements within the eastern United States. The development of such a facility at PTIA is congruent with that of the PTAA's stated interest in on-going airport development and expansion to meet the air service needs of the Triad and to be a major economic generator. The decision to site an overnight air cargo hub anywhere in the U.S., including at PTIA, is a decision reserved to the private sector and to local authorities (i.e., other than evaluation of proposals under NEPA, the FAA lacks statutory authority to participate in airport site selection for private aviation entities). PTAA states that its proposal is based on its plan to efficiently accommodate existing and projected aviation demand at PTIA. The development of an overnight, express air cargo hub at PTIA responds to industry and PTAA expectation that traditional air cargo traffic is increasing and, most importantly, that overnight express air cargo demand will continue to increase. PTAA's purpose for the proposed project is to allow and support improvements at PTIA to develop an overnight, express air cargo hub at PTIA and to provide airside, landside and surface transportation facilities that allow both the airport and the hub to be operated in an efficient manner. The PTAA has indicated to the FAA that the selection of the placement of the overnight cargo hub in either North W.\PIEDMONl1DEIS\Exsum\fnl_exs.doc\03/23/00 S-4 Summary Carolina or South Carolina was based on a business decision made by FedEx. After selecting the general geographic location for the hub, FedEx issued a Request for Proposals (RFP) in November, 1997 to air carrier certificated airports within the two-state area. Those airports that had an interest in the development of the overnight air cargo hub responded to the RFP with detailed proposals describing how the individual airport could accommodate the hub facility requirements. Between February 1998 and April 1998, FedEx undertook a detailed evaluation of each of the proposals as part of its site selection study. According to FedEx, the site selection study evaluated numerous criteria at each airport including the following: • Airport Operations - Runway Configuration, Runway Lengths, Instrument Approaches, Airfield Capacity, Runway Accessibility, Airspace and Air Traffic Control (ATC) Constraints, FAA and Radar Availability, Noise and Operational Concerns, Weather History, and Aircraft Rescue and Fire Fighting Availability. • Site Selection - Site Layout, Topography, Environmental Constraints, Site Access, Utilities, Airport Services Provided, Construction Restrictions, and Responses to the Request for Proposals. • Financial Analysis - System Form Expenses, Properties and Facilities Expenses, Salaries and Benefits, Taxes and Incentives. FedEx selected PTIA in April 1998 for the site of its hub because PTIA was the top-rated airport in the following selection criteria. According to FedEx, none of the other airports was as competitive with PTIA in all of these criteria. • Space required for the development of the size of the facility and aircraft apron proposed by FedEx; • Attractive low land lease rate; • Ability to develop parallel runways; • Ideal proposed hub site location between existing and future parallel runways; • Ability to operate head-to-head aircraft operations (from and to the same direction), thereby reducing taxi times; • No competition for runway use during hub arrival and departure times; • Good interstate access; • No unexpected or unresolvable environmental problems; • Outstanding incentive package, and • Operationally centered for proposed hub operations. Other than what is presented above, the information used by the air cargo hub operator to evaluate the proposals submitted by interested airport sponsors was not made available to FAA for review and W:\PIEDMONT\DEIS\Exsum\fnl_exs.doc\03/23/00 S-5 Summary evaluation. This information was considered confidential by the air cargo operator; therefore FAA had no means to independently evaluate either the selection criteria or the results of the selection process. MEET OPERATIONAL REQUIREMENTS OF AN OVERNIGHT, EXPRESS AIR CARGO HUB Establishment of an overnight, express air cargo hub at PTIA requires that certain airside, landside, and surface transportation improvements be implemented. The improvements are initially needed to meet the near- and long-term operational requirements of the overnight, express air cargo hub, within the near- term timeframe established by the carrier for PTIA. The improvements proposed by the PTAA are needed to facilitate development and efficient operation of an overnight, express air cargo hub consistent with FedEx business requirements. PTAA therefore seeks to support 48 daily FedEx operations (24 daily departures) by the year 2005 and 126 daily FedEx operations (63 daily departures) by the year 2009. Associated landside development is also needed that can support package processing activities at the rate of approximately 86,000 per night by the year 2005 and approximately 104,000 per night by the year 2009. All package processing must occur between the hours of 10:00 p.m. and 4:00 a.m. the following morning. The specific improvements that are needed include: • An airfield system capable of providing a redundant Transport-Category runway system having a minimum length of 9,000 feet; • An airfield system capable of allowing for the ability to conduct dual simultaneous independent operations to meet operational requirements in Instrument Flight Rules (IFR) or Instrument Meteorological Conditions (IMC), from 10:00 p.m. to 4:00 am, Monday through Friday, and • An air cargo hub development site of sufficient size, geometry and location to allow establishment and operation of the hub facility in a flexible and efficient manner. The above referenced operational levels were established by FedEx. PTAA states that for the desired full air cargo hub operational levels to be reached in 2005, Phase 1 of the hub facility must be constructed and operational by mid-year 2004. This would allow for a several month time period to test the sorting equipment and train employees. The proposed parallel runway is projected to be constructed and operational at the time that full aircraft and sorting operations would begin in early 2005. SUMMARY The purpose for the proposed project is to support locally sponsored projects that fulfill national public policy objectives, if such projects satisfy all FAA decision criteria and if the FAA determines that projects or their reasonable alternatives are environmentally sound. PTAA's purpose is to support the growth and development of PTIA such that the airport can support a major air cargo hub, is capable of accommodating the air transportation needs of the Triad, and it remains a major employment center and economic generator in the Triad. PTAA's need for the project is to develop facilities at PTIA that would fulfill the airside, landside and surface transportation operational requirements to support the development and efficient operation of an overnight, express air cargo hub facility (FedEx Mid-Atlantic Hub) at PTIA. W:\PIEDMONl1DEIS\Exsum\fni_exs.doc\03/23/00 S-6 Summary ALTERNATIVES Chapter 3.0, Alternatives, of the DEIS describes the alternatives screening process that was used by the FAA, presents a rigorous exploration of possible alternatives, provides reasoning as to why some alternatives were eliminated from detailed study, describes those reasonable alternatives that were retained for detailed evaluation, and presents a comparative analysis of the reasonable alternatives retained for detailed environmental impact evaluation. The range of alternatives examined in this DEIS has been generated to satisfy the purpose and need described in Chapter 2. PTAA submitted a proposal to the FAA for airside and landside developments that would meet the operational requirements for a Mid-Atlantic Cargo Hub submitted to it by FedEx. It is important to note that if airport improvements are to be built, the PTAA has the role of planning, constructing, and operating the runways at the airport. The FAA has generated alternatives, on its own and through the Scoping process (which yielded additional options submitted by an interested citizens group and the sponsor itself), that go somewhat beyond the limited consideration that might be afforded a proposal such as this. That is, in some circumstances such as these, where the sponsor's proposal is tied to sought-after business development with a particular commercial operator, it appears that the only alternative to the sponsor's proposed project is "No-Action". In this particular case, however, by concentrating on the near-term operational requirements of an overnight express air cargo hub, the FAA found that a larger range of alternatives should be identified and evaluated. As a result, off-site as well as a significant number of on-site alternatives were developed and explored which might meet the purpose and need for this project (provide redundant 9,000-foot Transport Category runways, provide for the ability to conduct dual simultaneous independent IFR operations, and provide a sort/distribution facility site of sufficient size, location and configuration to meet hub operational requirements). As described in Section 2.2, the role of the FAA in this case is to disclose and evaluate potential environmental impacts that may result from the sponsor's proposed project being considered, including impacts on the safe and efficient use of airspace. ALTERNATIVES EVALUATION PROCESS The FAA completed a thorough and objective review of reasonable alternatives to PTAA's proposed project at PTIA. CEQ regulations require that an agency look at "reasonable" alternatives, while 49 U.S.C. 47106(c)(C) requires as a condition to granting Federal funds, an analysis of "possible and prudent" alternatives for a new runway when significant impacts would occur." With those standards in mind, the FAA did not evaluate alternatives in detail if they showed no possibility of meeting the project purpose, as described previously, or no prospect of being built. The alternatives evaluation utilized a two-level evaluation process formulated to concentrate on the purpose and need for the proposed project and the reasonableness of the alternatives. Those alternatives that did not meet the purpose and need would be eliminated from further consideration. As the alternatives evaluation proceeded through each level of analysis, certain alternatives that did not meet the W:\PIEDMONMEIS\Exsum\fnl_exs.doc\03/23/00 S-7 Summary criteria were eliminated from further evaluation. Those that met the criteria continued on to the next level of analysis. At the conclusion of the second level of evaluation, those alternatives that remained were subject to detailed analysis in subsequent chapters of this DEIS. The first level of analysis evaluated whether the various alternatives met the purpose and need criteria specific to the airfield (development of the air cargo hub at PTIA, provide redundant 9,000-foot Transport Category runways, provide for the ability to conduct dual simultaneous independent IFR operations, provide a sort/distribution facility site of sufficient size, location and configuration to meet the proposed air cargo hub's operational requirements). Those alternatives that satisfied the first-level criteria were retained for evaluation under the second level of analysis. Level 2 of the alternatives analysis was designed to determine which alternatives were considered feasible, possible and prudent alternatives to the proposed project. These criteria were specific to the financial and physical environments affected by such a project. This level of the alternatives analysis considered "constructability" parameters including effects on infrastructure, amount of property acquisition, number of residences relocated and businesses impacted by each alternative, the cost of the alternatives and preliminary environmental impacts of the alternatives. Alternatives that were retained after the Level 2 evaluation are the subject of detailed analysis in Chapter 5.0, Environmental Consequences. ALTERNATIVES CONSIDERED The following describes the numerous on-site alternatives that FAA evaluated within this DEIS. Off-site alternative concepts that were initially considered by the FAA but which were not retained further consideration after the Level 1 screening process included other modes of transportation, development of a new airport, and use of other existing airports. When identifying on-site alternative locations for the development of a hub facility, technical considerations were grouped into two major categories: 1) the identification of available (or potentially available) on-airport land areas on which a sorting/distribution facility could be developed, and 2) the proximity of existing and future airfield improvements (runways, taxiways, and taxiway connectors) that are essential and required for the efficient operation of the hub. Identification of viable alternative locations on which to develop the sorting/distribution facility included review and assessment of the airport's existing runway/taxiway system, land areas, land uses, and land uses immediately adjacent to the airport. A systematic process to identify and assess the relative merits and opportunities for locations of the sorting/distribution facility and proposed parallel runway necessary for the development and operation of the overnight, express air cargo hub examined a total of five potential hub development sites and eight potential runway locations. This process yielded 40 possible alternative runway-sort/distribution facility scenarios which are depicted in Figure S-2 and fully described in Chapter 3.0, Alternatives, of the DEIS. Two additional alternative scenarios submitted by an interested group of citizens during Scoping for this DEIS and the airport sponsor were also evaluated and are described in detail in Chapter 3.0, Alternatives, of the DEIS. W.\PIEDMONTDEIS\Exsum\fnl exs.doc\03/23/00 S-8 Summary Runway Development Alternative Scenarios - Eight individual runway alternatives were developed and evaluated for their ability to meet the minimum facility and operational requirements addressed in the sponsor's proposal, which stressed the need for redundant 9,000-foot Transport-Category runways, and widely spaced parallel runways that allowed for the ability to conduct dual simultaneous independent IFR aircraft operations. For the parallel runway alternative scenarios, the minimum runway centerline separation for dual simultaneous independent all-weather operations (3,400 feet) as prescribed by FAA Advisory Circular 150/5300-13, Change 5, Standards and Recommendations for Airport Design was used. In addition to these eight runway configurations, the FAA considered the runway development alternative submitted by interested citizens during Scoping and a runway alternative submitted by the PTAA for their ability to meet all of the Level 1 alternatives screening criteria. Those runway alternative scenarios that did not meet the operational/capacity needs of the air cargo hub operator through the year 2019 were not retained for further consideration after the Level 1 screening analysis because these alternatives did not fulfill the purpose and need for the proposed project. Those runway alternative scenarios that did meet the Level 1 purpose and need criteria were retained for additional analysis in Level 2 of the alternatives screening process. Air Cargo Sorting/Distribution Facility (FedEx Mid-Atlantic Hub) Site Alternative Scenarios- Five potential air cargo sorting/distribution facility site alternatives that would meet the size and geometric requirements (a site having a rectangular shape with approximately 300 contiguous acres) were identified and evaluated by the FAA. Each alternative site location was based solely on the required size, geometry, and relative proximity to existing or planned airport and surface transportation facilities. Each site possessed unique attributes and opportunities with respect to meeting the proposed air cargo sorting and distribution facility requirements as presented by the sponsor. The FAA also considered the air cargo sorting/distribution facility site development alternative submitted by interested citizens during Scoping for the DEIS. EVALUATION OF PTIA RUNWAY AND SORT/NG/DISTRIBUTION FACILITY SITE ALTERNATIVES The evaluation of on-site alternatives was based on an examination of each of the previously described eight potential runway configurations integrated with each of the previously described five potential sorting/distribution facility development sites. In addition, the evaluation included an alternative concept submitted by a group of citizens during Scoping and an alternative submitted by the airport sponsor after the DEIS was started. This yielded a total of 42 distinct alternative scenarios. Each of the 42 alternative development scenarios was subject to the two-level alternatives screening process to determine which alternatives were the most reasonable, feasible and prudent for detailed evaluation in this DEIS. The following is a summary of the results of the screening process for these alternatives. The discussion is presented based on each of the runway alternatives, and expanded to discuss the implications of each of the site alternatives. Table S-1 depicts how each alternative passed through the two-level alternatives screening process. No Action Alternative - The No-Action Alternative would not meet any of the purpose and need criteria for the proposed project at PTIA. This alternative would not locate an air cargo sorting/distribution facility at PTIA, provide redundant 9,000-foot Transport-Category runways, provide the ability to conduct dual W.\PIEDMONl1DEIS\Exsum\fnl_exs.doc\03123100 S-9 Summary simultaneous independent IFR operations, or provide a sorting/distribution facility site that meets the operational requirements of the air cargo hub. As described in Section 2.0, Purpose and Need, the proposed improvements are needed for the air cargo operator to maximize the efficiency of its operations, particularly during the push-back-to-wheels-up and departure window timeframe. Although the No-Action Alternative did not meet the purpose and need criteria, it was retained for further consideration in Level 2 of the alternatives screening to ensure a complete environmental impact evaluation and to provide a baseline comparison. Alternatives X-A through X-E - Runway-sort/distribution facility site Alternatives X-A through X-E would only partially meet the purpose and need criteria for the proposed project at PTIA. All of these alternatives would locate the air cargo sorting/distribution facility at PTIA, provide redundant 9,000-foot Transport-Category runways, and provide approximately 300 contiguous acres in a rectangular shape for the development of the hub facility. However, none of these alternatives would provide the ability to conduct . dual simultaneous independent IFR operations, the capability to conduct head-to-head operations during times of peak air cargo operations, or develop a sorting/distribution facility site located between parallel runways. As described in Chapter 2.0, Purpose and Need, and quantified in the TAAM analysis, all three of these criteria are needed to facilitate overnight cargo hub operations, particularly during the push-back-to-wheels-up departure timeframe. The use of perpendicular runways under the Alternative X-A through X-E scenarios would result in operational conditions that would lessen the overall efficiency of aircraft operations such as dependent operations (operations on one runway affect/limit operations on the other runway) and increased runway crossings, change local and potentially regional flight patterns (more daytime and nighttime operations on Runway 14/32 in an east-west orientation as opposed to north-south orientation under existing operational conditions on Runway 5/23) and result in potential safety concerns (increased use of a designated crosswind runway and increased runway crossings) at PTIA. The development of a hub facility that is not located between parallel runways would result in the air cargo operator not being able to meet most of its designated push-back-to-wheels-up departure timeframe. Since none of these five alternatives met all of the Level 1 purpose and need criteria, none were retained for further consideration in this DEIS. Alternatives W1-A through W1-E - Runway-sort/distribution facility site Alternatives W1 -A through W1-E would only partially meet the purpose and need criteria for the proposed project at PTIA. All of these alternatives would locate the overnight, express air cargo hub at PTIA, provide redundant 9,000- foot Transport-Category runways, provide the ability to conduct dual simultaneous independent IFR operations and provide the capability to conduct head-to-head operations during times of peak air cargo operations. However, Alternative W1-A did not meet all of the Level 1 screening criteria because the 4,300 foot centerline-to-centerline separation distance between existing Runway 5R/23L and proposed Runway 5U23R would not provide a sorting/distribution facility site of sufficient size to meet operational needs. Alternatives W1 -B, W1 -C, W1 -D, and W1 -E did not meet the Level 1 screening criteria because they would not provide a sorting/distribution facility site located between parallel runways, which, based on the TAAM analysis, is critical to meeting the operational needs of the air cargo carrier. The location of the sort/distribution facility site associated with Alternative W1-C does not meet FAA Standards and Recommendations for Airport Design (Advisory Circular 150/5300-13) because a portion of the proposed site (approximately 10 percent) would fall within the future RPZ of proposed parallel Runway 5U23R. W:\PIEDMONl1DEIS\Exsum\fnl_exs.doc\03/23/00 S-10 Summary FAA's design guidelines, which were developed to enhance the protection of people and property on the ground, prohibit the development of places of public assembly within a RPZ, and further recommends that it is desirable that the RPZ remain clear of all objects. The development of the sorting/distribution facility within the RPZ would not be in keeping with the above referenced FAA design and safety standard. Since none of these five alternatives met all of the Level 1 purpose and need screening criteria, they were not retained for further evaluation in this DEIS. Alternatives W2 -A through W2-E - Alternative W2-A, which is the sponsor's proposed project, would meet all of the Level 1 purpose and need criteria; therefore, it was retained for further evaluation in the Level 2 analysis. Runway-sorting/distribution facility site Alternatives W2-13 through W2-E would only partially meet the purpose and need criteria for the proposed project. All of these alternatives would locate the overnight, express air cargo hub at PTIA, provide redundant 9,000-foot Transport-Category runways, provide the ability to conduct dual simultaneous independent IFR operations and provide the capability to conduct head-to-head operations during times of peak air cargo operations. However, none of these alternatives would provide a sorting/distribution site located between parallel runways, which, as described in the TAAM analysis, is critical to meeting cargo hub operational needs. The location of the sort/distribution facility site associated with Alternative W2-C does not meet FAA Standards and Recommendations for Airport Design (Advisory Circular 150/5300-13) because a large portion of the proposed site (approximately 40 percent) would fall within the future RPZ of proposed parallel Runway 5U23R. FAA's design guidelines, which were developed to enhance the protection of people and property on the ground, prohibit the development of places of public assembly within a RPZ, and further recommends that it is desirable that the RPZ remain clear of all objects. The development of the sorting/distribution facility within the RPZ would not be in keeping with the above referenced FAA design and safety standard. Since none of these four alternatives met all of the Level 1 purpose and need criteria, they were not retained for further evaluation in this DEIS. Alternatives W3-A through W3-E - Runway-sorting/distribution facility site Alternative W3-A would locate the overnight, express air cargo hub at PTIA, provide redundant 9,000-foot Transport-Category runways, provide the ability to conduct dual simultaneous independent IFR operations, provide the capability to conduct head-to-head operations during times of peak air cargo operations, locate the sorting/distribution facility site between the parallel runways to meet operational needs. Since this alternative scenario met all of the Level 1 purpose and need criteria, it was retained for further evaluation in the Level 2 analysis. Alternatives W3-13, W3-C, W3-D, and W3-E did not meet all of the Level 1 criteria because they would not provide a sorting/distribution facility site between the parallel runways, which is critical to meeting operational needs. The location of the sort/distribution facility site associated with Alternative W3-C does not meet FAA Standards and Recommendations for Airport Design (Advisory Circular 150/5300-13) because a large portion of the proposed site (approximately 50 percent) would fall within the future RPZ of proposed parallel Runway 5U23R. FAA's design guidelines, which were developed to enhance the protection of people and property on the ground, prohibit the development of places of public assembly within a RPZ, and further recommends that it is desirable that the RPZ remain clear of all objects. The development of the sorting/distribution facility within the RPZ would not be in keeping with the above referenced FAA design and safety standard. Since none of these four alternatives met all of the Level 1 purpose and need criteria, they were not retained for further evaluation in this DEIS. W.\PIEDMOMIDEIS\Exsum\inl_exs.doc\03/23/00 S-11 Summary Alternatives E7-A through Ei-E - Runway-sorting/distribution facility site Alternatives E1-A through E1-E would only partially meet the purpose and need criteria for the proposed project. All of these alternatives would locate the overnight, express air cargo hub at PTIA, provide redundant 9,000-foot Transport-Category runways, provide the ability to conduct dual simultaneous independent IFR operations and provide the capability to conduct head-to-head operations during times of peak air cargo operations. However, Alternatives E1-A, E1-C, and E1-D did not meet the Level 1 criteria because they did not provide a sorting/distribution facility site between the parallel runways. Alternative El -B and El -E did not meet the Level 1 purpose and need criteria because with the 3,400-foot runway centerline separation, they did not provide a sorting/distribution facility site of sufficient size to meet the air cargo carrier's operational requirements. In addition, the location of the proposed parallel runway in all of the E1 alternatives would require the relocation of existing railroad infrastructure, which would take a minimum of 5 to 7 years to accomplish because of the required coordination with other agencies (Surface Transportation Board), and because new construction could not occur until the railroad was relocated. Since none of these five alternatives met all of the Level 1 purpose and need criteria, they were not retained for further evaluation in this DEIS. Alternatives E2-A through E2-E- Runway-sorting/distribution facility site Alternatives E2-A through E2-E would only partially meet the purpose and need criteria for the proposed project. All of these alternatives would locate the overnight, express air cargo hub at PTIA, provide redundant 9,000-foot Transport- Category runways, provide the ability to conduct dual simultaneous independent IFR operations and provide the capability to conduct head-to-head operations during times of peak air cargo operations. However, Alternatives E2-A, E2-C, and E2-D did not meet the Level 1 criteria because they did not provide a sorting/distribution facility site between the parallel runways. Alternatives E2-B and E2-E did not meet the Level 1 purpose and need criteria because with the 4,300 foot runway separation, these alternatives would not provide a sorting/distribution site of sufficient size to meet the air cargo carrier's operational requirements. All of the "E2" parallel runway alternatives would require the relocation of existing railroad infrastructure, which, as discussed for the E1 Alternatives, would take a minimum of 5 to 7 years to accomplish. Since none of these five alternatives met all of the Level 1 purpose and need criteria, they were not retained for further evaluation in this DEIS. Alternatives N-A through N-E - Alternatives N-D and N-E met all of the Level 1 purpose and need criteria; therefore, these alternatives were retained for further evaluation in the Level 2 analysis. Alternatives N-A and N-C did not meet the Level 1 criteria because they did not provide a sorting/distribution facility site between the parallel runways, which is critical to meeting the cargo hub's operational needs. Alternative N-B did not meet the Level 1 purpose and need criteria because it did not provide a sorting/distribution facility site of sufficient size to meet the air cargo hub's operational requirements. Since none of these three alternatives met all of the Level 1 purpose and need criteria, they were not retained for further evaluation in this DEIS. Alternatives S-A through S-E - Alternatives S-A, S-B, S-D, and S-E did not meet the Level 1 criteria because they did not provide a sorting/distribution facility site between the parallel runways. Alternative S- C did not meet the Level 1 purpose and need criteria because it did not provide a sorting/distribution W.\PIEDMONl1DE1S\Exsum\fnl_exs.doc\03123100 5-12 Summary facility site of sufficient size to meet the air cargo hub's operational requirements. All of the "S" parallel runway alternatives would require the relocation of existing railroad infrastructure, which, as discussed for the E1 and E2 Alternatives, would take a minimum of 5 to 7 years to accomplish. Since none of these five alternatives met all of the Level 1 purpose and need criteria, they were not retained for further evaluation in this DEIS. Citizens Scoping Alternative - Review of the citizens Scoping alternative indicates that it would only partially meet the Level 1 purpose and need criteria for the proposed project at PTIA. This alternative would locate the air cargo facility at PTIA, provide redundant 9,000-foot Transport-Category runways, and provide a site of approximately 300 acres for the development of the air cargo sorting/distribution facility. However, this alternative would not provide the ability to conduct dual simultaneous independent IFR operations, it would not provide the ability to conduct head-to-head operations during times of peak air cargo operations and it would not provide a sorting/distribution facility site located between parallel runways. In terms of the proposed runway improvements associated with this alternative, the proposed 700- to 1,000-foot relocation of the existing Runway 5 threshold does not meet FAA Standards and Recommendations for Airport Design (Advisory Circular 150/5300-13) because it would not provide sufficient distance between the relocated end of Runway 5 and existing Runway 14/32 to provide a standard RSA, jet-blast protection, or sufficient TERPS clearance for Runway 14/32. The use of perpendicular runways under the citizens alternative would result in operational conditions that would lessen the overall efficiency of aircraft operations such as dependent operations (operations on one runway would affect/limit operations on the other runway) and increased runway crossings, change local and potentially regional flight patterns (more daytime and nighttime air carrier and air cargo operations on Runway 14/32 in an east-west orientation as opposed to north-south orientation under existing operational conditions on Runway 5/23) and result in potential safety concerns such as increased use of a designated crosswind runway and increased runway crossings at PTIA. The location of the proposed sorting/distribution facility site associated with this alternative also does not meet FAA Standards and Recommendations for Airport Design (Advisory Circular 150/5300-13) because a large portion of the proposed site (90 percent) would fall within the future RPZ of proposed 10,000 foot parallel Runway 5U23R, as depicted on PTIA's current ALP. The FAA's aforementioned design guidelines, which were developed to enhance the protection of people and property on the ground, prohibit the development of places of public assembly within a RPZ, and further recommend that it is desirable that the RPZ remain clear of all objects. The development of the sorting/distribution facility within the RPZ would therefore not be consistent with the above referenced FAA safety and design standards. The development of the sorting/distribution facility in the location and configuration proposed in the citizens alternative scenario, based on PTIA's current ALP, would also result in constraints that would preclude the full development of the proposed air cargo sorting/distribution facility because it would not provide an adequate balance of airfield, surface transportation access, and operational staging space. To address these issues, the citizens alternative further proposes that the future 10,000-foot parallel runway depicted on the PTIA ALP be shortened to a length of 7,000 feet. This would relocate the future Runway 5L RPZ to the north, such that it would not conflict with the citizen's proposed location of the air W:\PIEDMONTDEIS\Exsum\fnl_exs.doc\03/23/00 S-13 Summary cargo sort/distribution facility. However, the 7,000-foot parallel runway proposed by the citizens is not consistent with PTIA's ALP, and it would preclude development of a parallel runway of sufficient length and utility to meet the operational requirements of the air cargo hub. As calculated by the citizens submitting this alternative for FAA consideration, impacts associated with the sorting/distribution facility portion of this alternative would include the acquisition and relocation of approximately 26 commercial and 63 residential properties, the relocation of the airport fire station, the closure of a portion of Regional Road, from the intersection Bryan Boulevard to the intersection of U.S. Highway 421, and the isolation (taking) of an existing 1.4-acre cemetery. FAA's analysis of this alternative indicates that because the sorting/distribution facility site geometry must be contiguous (as stated by the sponsor), this alternative would require the relocation of the airport fire station, a City of Greensboro fire station, the primary BellSouth (fiber optic) switching station and the taking of an existing 1.4-acre cemetery, which would result in an impact to an historic resource. Roadway infrastructure impacts would include the closure of a portion of Regional Road, from the intersection Bryan Boulevard to the intersection of U.S. Highway 421. FAA gave full consideration to the citizen's alternative using the same Level 1 criteria as was used to evaluate all of the other on and off-site alternatives. FAA's evaluation concluded that this alternative did not meet all of the Level 1 purpose and need criteria, therefore it was not retained for further consideration in this DEIS. Alternative W1-A1 - In August 1999, the PTAA requested that the FAA consider in the DEIS an additional "west" runway alternative that was developed by the PTAA as a result of detailed planning efforts associated with the ongoing PTIA Master Plan Update. This alternative, designated as Alternative W1-All, is similar to Alternative W1-A. However, under this alternative, the centerline separation distance between the proposed new parallel runway and existing Runway 5/23 would be 5,088 feet, as compared to Alternative W1 -A, in which it would be 4,300 feet. This increased runway centerline separation distance provides a sorting/distribution facility site of sufficient size, located between the parallel runways, to meet the operational needs of the air cargo carrier. Under this alternative, the threshold of the end of new Runway 23R would be shifted approximately 1,032 feet to the southwest, the same as in Runway Alternative W3. The increased separation distance between the parallel runways associated with Alternative W1-A1 would result in a need to relocate a 2-mile segment of Bryan Boulevard to the west of its current location. A new interchange for Bryan Boulevard and Old Oak Ridge Road would also need to be developed. Review of Alternative W1-A1 indicates that it would meet all of the Level 1 purpose and need criteria in that it would locate the overnight, express air cargo facility at PTIA, provide redundant 9,000-foot Transport-Category runways; provide the ability to conduct dual simultaneous independent IFR operations and the capability to conduct head-to-head operations during times of peak air cargo operations, and it would provide for a sorting/distribution facility site of sufficient size, located between the parallel runways, to meet the air cargo hub's operational needs. Since Alternative W1-A1 met all of the Level 1 purpose and need criteria, it was retained for further consideration. W:\PIEDMONT\DEIS\Exsum\fnl exs.doc\03/23/00 S-14 Summary ALTERNATIVES RETAINED FOR DETAILED EVALUATION Five runway-sort/distribution facility alternatives (W2-A, W3-A, N-D, N-E and W1-A1) as well as the No- Action Alternative were retained through the two level screening process. Table S-2 and the following paragraphs present a summary of the results of the evaluation of each of these alternatives. No Action Alternative - (See Figure S-3) The No-Action Alternative infers the overnight, express air cargo sorting and distribution facility (FedEx Mid-Atlantic Hub) would not be developed at PTIA. This alternative would involve no new construction of airside facilities or landside facilities associated with the air cargo facility, and no other PTIA airside and landside developments beyond those that are already programmed or undertaken by the PTAA for safety and maintenance reasons. The PTAA plans several surface transportation improvement projects that would be initiated whether or not the air cargo facility were to locate at PTIA. These projects would be funded by the FHWA and NCDOT. Infrastructure impacts from development of the surface transportation projects associated with the No-Action Alternative include closure and relocation of a portion of Regional Road, realignment of a portion of Old Oak Ridge Road, construction of a new interchange for Bryan Boulevard and Old Oak Ridge Road, construction of a new airport entrance interchange for existing North Triad Boulevard and development of a new interchange for South Triad Boulevard. Implementation of the No-Action Alternative would require the relocation of one home and the acquisition of approximately 13.66 acres of property for right-of-way acquisition for the roadway projects. The right-of- way acquisition would include any realigned roadway as well as the cleared/maintained safety areas off the sides of the roadways. The surface transportation improvements would result in adverse impacts to approximately 9.8 acres of wetlands and 23.1 acres located within the 100-year floodplain (see Chapter 5.0, Environmental Consequences). This alternative would not result in direct or indirect impacts to DOT Section 303(c) resources or direct impacts to Section 106 Historic Resources. Existing indirect impacts to one Section 106 historic architectural site (Campbell-Gray Farm) from aircraft generated noise would be lessened, with DNL levels decreasing from DNL 70.5 dBA in 1998 to DNL 68.6 dBA in Phase 1 and DNL 69.2 dBA in Phase 2. Based on FAA noise compatibility guidelines, noise levels from aircraft operations would be above FAA's threshold of compatibility (which is DNL 65 dBA) at this site with the No-Action Alternative. The total cost for the No-Action Alternative is estimated to be approximately $25.7million, including construction, acquisition, and relocation-and wetlands mitigation. Alternative W2 -A - (See Figure S-3) Surface transportation impacts from development of the parallel runway associated with Alternative W2-A include partial closure of Lebanon Road west of Drum Road, Brush Road north of Canoe Road, and a small portion of North Regional Road west of Bryan Boulevard. Partial closure of Caindale Drive east of the Airport Surveillance Radar (ASR) would also be required. Infrastructure impacts from the development of the air cargo sorting/distribution facility site associated with Alternative W2-A, north of the existing airport terminal, include closure of Air Cargo Road and partial closures of North Service Road and Inman Road south, of the Bryan Boulevard/Inman Road intersection. PTAA has the option of either purchasing lands within the RPZ's or obtaining avigation easements over the individual properties. If PTAA purchases all property within the proposed parallel runway RPZ's, W:\PIEDMONl1DE1S\Exsum\fnl_exs.doc\03/27/00 S-15 Summary relocation impacts north of the airport would include six residential properties on Phillipsburg Court, and one residential property on Old Oak Ridge Road. RPZ acquisition-related off-airport relocation impacts southwest of the airport include two residential properties on Canoe Road east of Burgess Road, and nine industrial properties along Burgess Road north of Market Street. Relocation impacts from development of the air cargo sorting/distribution facility site associated with Alternative W2-A, north of the airport would include one commercial property along Inman Road. On-airport relocation impacts include all rental car turnaround, servicing, and parking facilities (six buildings), a parking lot, Dobbs kitchen, and air cargo facilities (two multi-tenant sort/distribution buildings). Implementation of Alternative W2-A would require the acquisition of approximately 88.37acres of property, primarily to enable the PTAA to own the RPZs for proposed parallel Runway 5U23R. The total cost for Alternative W2-A, including property acquisition and relocation, construction of the parallel runway, taxiways and associated NAVAIDS, air cargo sorting/distribution facility site preparation, and mitigation for wetland impacts would be approximately $221.3 million. A complete discussion of environmental impacts associated with this alternative is contained in Chapter 5.0, Environmental Consequences. In summary, direct environmental impacts associated with construction of Alternative W2-A include the relocation of nine homes (approximately 21 people), one commercial facility, and nine industrial facilities, and adverse impacts to approximately 32.3 acres of wetlands and 36.6 acres located within the 100-year floodplain (see Chapter 5.0, Environmental Consequences). This alternative would not result in direct or indirect impacts to DOT Section 303(c) resources or direct impacts to Section 106 Historic Resources. Aircraft generated indirect noise impacts to one Section 106 historic architectural site (Campbell-Gray Farm) would decrease when compared to the 1998 existing condition, with DNL levels decreasing from DNL 70.5 dBA in 1998 to DNL 70.2 dBA in Phase 1. Compared to the No-Action Alternative, DNL levels would increase slightly from DNL 68.6 dBA to DNL 70.2 dBA in Phase 1 and from DNL 69.2 dBA to DNL 71.0 dBA in Phase 2. Based on FAA noise compatibility guidelines, noise levels from aircraft operations would be above FAA's threshold of compatibility (which is DNL 65 dBA) at this site with Alternative W2-A. Alternative W3-A - (See Figure S-3) Surface transportation impacts from the development of the parallel runway associated with Alternative W3-A include partial closure of Lebanon Road west of Drum Road, Brush Road north of Canoe Road, and a small portion of North Regional Road west of Bryan Boulevard. The partial closure of Caindale Drive east of the ASR would also be required. Surface transportation impacts from the development of the sorting/distribution facility site associated with Alternative W3-A, north of the existing airport terminal include closure of Air Cargo Road and partial closures of North Service Road and Inman Road, south of the Bryan Boulevard/Inman Road intersection. PTAA has the option of either purchasing lands within the RPZ's or obtaining avigation easements over the individual properties. If PTAA purchases all properties within the RPZs, relocation impacts from the development of the parallel runway portion of Alternative W3-A would include two residential properties at the corner of Brush Road and Lebanon Road, two residential properties on Canoe Road east of Burgess Road, one residential property along Old Oak Ridge Road, and 13 industrial properties along Burgess Road north of Market Street.

WAPIEDM0NT\DEIS\Ch_3\TBL 34-1&S-2.doc\03/27/00 facility site associated with Alternative W3-A, north of the airport, include one commercial property along Inman Road. On-airport relocation impacts would include all rental car turnaround, servicing, and parking facilities (six buildings), a parking lot, Dobbs kitchen, and air cargo facilities (two multi-tenant sort/distribution buildings). Construction of Alternative W3-A would require the acquisition of approximately 89.89 acres of property, primarily to enable the PTAA to own the RPZs for proposed parallel Runway 5U23R. The total cost for Alternative MA including the parallel runway, taxiway and associated NAVAIDS, hub site preparation, acquisitions and relocations, and wetland mitigation would be approximately $226.6 million. A complete discussion of environmental impacts associated with this alternative is contained in Chapter 5.0, Environmental Consequences. In summary, direct environmental impacts associated with construction of Alternative W3-A include relocation of five homes (approximately 12 people), 13 industrial properties, and one commercial property, and adverse impacts to approximately 29.8 acres of wetlands and 34.6 acres located within the 100-year floodplain (see Chapter 5.0, Environmental Consequences). This alternative would not result in direct or indirect impacts to Section 303(c) resources or direct impacts to Section 106 Historic Resources. Aircraft generated indirect noise impacts to one Section 106 historic architectural site (Campbell-Gray Farm) would decrease when compared to the 1998 existing condition, with DNL levels decreasing from DNL 70.5 dBA in 1998 to DNL 70.2 dBA in Phase 1. Compared to the No-Action Alternative, DNL levels would increase slightly from DNL 68.6 dBA to DNL 70.2 dBA in Phase 1 and from DNL 69.2 dBA to DNL 71.0 dBA in Phase 2. Based on FAA noise compatibility guidelines, noise levels from aircraft operations would be above FAA's threshold of compatibility (which is DNL 65 dBA) at this site with Alternative W3-A. Alternative N-D - (See Figure S-3) Surface transportation impacts to the west of the airport from the development of the extension of existing Runway 14/32 would consist of the partial closure of Lebanon Road, west of Brush Road. Surface transportation impacts to the west of the airport from the development of new Runway 14U32R would consist of the closure of Hollandsworth Drive, Hollandsworth Court, and Calico Drive. Impacts to on-airport roads would include closure of Air Cargo Road north of Bryan Boulevard and North Service Road, and the realignment of North Triad Boulevard. Impacts to local roadways at the east end of the new Runway 14L/32R and parallel taxiway include partial closure of Stage Coach Trail north of Holly Crest Court, partial closure of Ballinger Road west of Breezewood Road, and the full closure of Wagon Wheel Drive, Carriage Lane, and Coach Hill Road. Infrastructure impacts from development of the air cargo sorting/distribution facility site associated with Alternative N-D, west of the airport, include closure of Bentley Road, Business Park Drive, and Skyway Drive, and the partial closure of the easternmost portion of Caindale Drive. PTAA has the option of either purchasing lands within the RPZ's or obtaining avigation easements over the individual properties. If PTAA purchases all lands required for the sorting/distribution facility site and the RPZ's, off-airport relocation impacts west of the airport associated with the runway portion of Alternative N-D would include two residential properties along Caindale Drive, four residential properties along Hollandsworth Drive, two residential properties along Hollandsworth Court, and four residential properties along Calico Drive. The Airport Surveillance Radar (ASR) located on Caindale Drive would \\clnt0l\wp_wpro\PIEDMONnDEIS\Exsum\fnl_exs.doc\03/27/00 S-17 Summary also require relocation. Off-airport relocation impacts east of the airport from the parallel runway include four residential properties along Stage Coach Trail, 10 residential properties along Breezewood Road, 10 residential properties along Wagon Wheel Drive, 15 residential properties along Carriage Lane, 12 residential properties along Coach Hill Road, and one residential property along Ballinger Road. Off- airport relocation impacts associated with the development the sorting/distribution facility site associated with Alternative N-D, west of the airport, include Friendship Baptist Church and cemetery, 12 residential, and 2 commercial properties along Bentley Road, 2 industrial properties along Caindale Drive, and 8 industrial properties along Business Park Drive. Relocation impacts to on-airport commercially leased parcels from the parallel runway include the relocation of all rental car turnaround, servicing and parking facilities (six buildings), a parking lot, Dobbs kitchen, fuel farm, and air cargo (two multi-tenant sort/distributions building). In addition, the implementation of the cumulative surface transportation projects would require the relocation of one residential property on Old Oak Ridge Road. Construction of Alternative N-D would require the acquisition of approximately 315.01 acres of property, primarily for sufficient land area to develop the sorting/distribution facility site and to enable the PTAA to own the RPZs for proposed parallel Runway 14U32R. The total cost for Alternative N-D, including the parallel runway, extension of Runway 14/32, taxiways, NAVAIDS, air cargo site preparation, property acquisition and relocation, and wetland mitigation would be approximately $328.5 million. A complete discussion of environmental impacts associated with this alternative is contained in Chapter 5.0, Environmental Consequences. In summary, direct environmental impacts associated with construction of Alternative N-D include relocation of 77 homes (approximately 182 people), two commercial facilities, and 10 industrial properties and adverse impacts to approximately 36.8 acres of wetlands and 49.6 acres located within the 100-year floodplain (see Chapter 5.0, Environmental Consequences). This alternative would result in indirect impacts from aircraft generated operational noise to 10 Section 303(c) resources and indirect impacts from aircraft generated operational noise to three Section 106 historic architectural properties (Guilford College, Roy Edgerton House and New Garden Friends Cemetery). Alternative W1-A1 - (See Figure S-3) Surface transportation impacts from development of the parallel runway associated with Alternative W1-A1 would include the relocation of a 2 mile segment of Bryan Boulevard (and demolition of the existing alignment), and partial closure of Lebanon Road west of Drum Road, Brush Road north of Canoe Road, and a small portion of North Regional Road west of Bryan Boulevard. Partial closure of Caindale Drive east of the Airport Surveillance Radar (ASR) would also be required. Surface transportation impacts from the development of the sorting/distribution facility site associated with Alternative W1-Ai, north of the existing airport terminal, would include closure of Air Cargo Road and partial closures of North Service Road and Inman Road south of the Bryan Boulevard/Inman Road intersection. PTAA has the option of either purchasing lands within the RPZ's or obtaining avigation easements over the individual properties. If PTAA purchases all properties within the RPZs, relocation impacts from the development of the parallel runway portion of Alternative W1-Ai would include six residential properties along Brush Road north of Canoe Road, two residential properties along Drum Road south of Lebanon \\clM01\wp_wpro\PIEDMONTDEIS\Exsum\inl_exs.doc\03/27/00 S-18 Summary Road, three residential properties on Canoe Road east of Burgess Road, 17 industrial properties and one commercial property along Burgess Road north of Market Street, and two commercial properties along Canoe Road west of Brush Drive. Off-airport relocation impacts from development of the sorting/distribution facility site associated with Alternative W1-Al, north of the airport would include one commercial property along Inman Road. On-airport relocation impacts include all rental car turnaround, servicing, and parking facilities (six buildings), a parking lot, Dobbs kitchen, and air cargo facilities (two multi-tenant sort/distribution buildings). Relocation impacts from the realignment of Bryan Boulevard and the new Bryan Boulevard/Old Oak Ridge Road interchange include 35 residential properties in the College Lakes development, located south of Old Oak Ridge Road and east of Pepperdine Road. Implementation of Alternative W1-A1 would require the acquisition of approximately 154.74 acres of property, primarily to enable the PTAA to own the RPZs for proposed parallel Runway 5U23R. The total cost for Alternative W1-Al, including property acquisition, and relocation construction of the parallel runway, taxiways and associated NAVAIDS, sorting/distribution facility site preparation, and mitigation for wetland impacts would be approximately $227.3 million. A complete discussion of environmental impacts associated with this alternative is contained in Chapter 5.0, Environmental Consequences. In summary, direct environmental impacts associated with construction of Alternative W1-Ai include the relocation of 47 homes (approximately 111 people), 17 industrial, and four commercial facilities and adverse impacts to approximately 27.3 acres of wetlands and 25.4 acres located within the 100-year floodplain (see Chapter 5.0, Environmental Consequences). This alternative would not result in direct or indirect impacts to DOT Section 303(c) resources or direct impacts to Section 106 Historic Resources. Aircraft generated indirect noise impacts to one Section 106 historic architectural site (Campbell-Gray Farm) would decrease when compared to the 1998 existing condition, with DNL levels decreasing from DNL 70.5 dBA in 1998 to DNL 70.2 dBA in Phase 1. Compared to the No-Action Alternative, DNL levels would increase slightly from DNL 68.6 dBA to DNL 70.2 dBA in Phase 1 and from DNL 69.2 dBA to DNL 71.0 dBA in Phase 2. Based on FAA noise compatibility guidelines, noise levels from aircraft operations would be above FAA's threshold of compatibility (which is DNL 65 dBA) at this site with Alternative W 1-A1. Alternative N-E - (See Figure S-3) Surface transportation impacts to the west of the airport from the development of the extension of existing Runway 14/32 would consist of the partial closure of Lebanon Road, west of Brush Road. Surface transportation impacts to the west of the airport from the development of new Runway 14U32R would consist of the closure of Hollandsworth Drive, Hollandsworth Court, and Calico Drive. Impacts to local roadways at the east end of the new Runway 14U32R and parallel taxiway include the closure of Stage Coach Trail north of Holly Crest Court, partial closure of Ballinger Road, west of Breezewood Road, and the closure of Wagon Wheel Drive, Carriage Lane, and Coach Hill Road. Surface Transportation impacts from development of the air cargo sorting/distribution facility site associated with Alternative N-E, east of the airport, would consist of partial closure of Radar Road, and the closure of an existing railroad spur. On-airport roadway impacts would include closure of Air Cargo Road north of Bryan Boulevard and North Service Road, and the realignment of North Triad Boulevard. \\clnt07\wp_wpro\PIEDMOMIDEIS\Exsum\fnl_exs.doc\03/27/00 S-19 Summary PTAA has the option of either purchasing lands within the RPZ's or obtaining avigation easements over the individual properties. If PTAA purchases all lands required for the RPZ's, off-airport relocation impacts west of the airport associated with the new runway portion of Alternative WE would include two residential properties along Caindale Drive, four residential properties along Hollandsworth Drive, two residential properties along Hollandsworth Court, and four residential properties along Calico Drive. Off- airport relocation impacts east of the airport from the new parallel runway would include four residential properties along Stage Coach Trail, 10 residential properties along Breezewood Road, 10 residential properties along Wagon Wheel Drive, 15 residential properties along Carriage Lane, 12 residential properties along Coach Hill Road, and one residential property along Ballinger Road. Off-airport relocation impacts from development the sorting/distribution facility site associated with Alternative N-E, east of the airport, include seven industrial buildings (plus approximately five support buildings) along Radar Road. On-airport relocations would consist of commercially leased parcels including the rental car turnaround, servicing and parking facilities (six buildings), a parking lot, Dobbs kitchen, fuel farm, air cargo (two multi-tenant sort/distribution buildings) and six commercially leased large maintenance hangars (with six support buildings) along Radar Road. In addition, the implementation of the cumulative surface transportation projects would require the relocation of one residential property on Old Oak Ridge Road. Construction of Alternative WE would require the acquisition of approximately 266.14 acres of property, primarily for sufficient land area to develop the sorting/distribution facility site and to enable the PTAA to own the RPZs for proposed parallel Runway 14U32R. The total cost for Alternative N-E, including the parallel runway, extension of Runway 14/32, taxiways, NAVAIDS, air cargo site preparation, property acquisition and relocation, and wetland mitigation would be approximately $414.6 million. A complete discussion of environmental impacts associated with this alternative is contained in Chapter 5.0, Environmental Consequences. In summary, direct environmental impacts associated with construction of Alternative N-E include relocation of 65 homes (approximately 154 people), 13 commercial / industrial facilities (plus associated support buildings) and adverse impacts to approximately 31.3 acres of wetlands and 46.4 acres located within the 100-year floodplain (see Chapter 5.0, Environmental Consequences). This alternative would result in indirect impacts from aircraft generated operational noise to ten Section 303(c) resources and indirect impacts from aircraft generated operational noise to two Section 106 historic architectural properties (Shaw-Cude House and New Garden Friends Cemetery). PREFERRED ALTERNATIVE(S) The sponsor of the proposed project, the PTAA, has approached FAA with a proposed airport development program (proposed project) for PTIA, which would provide airside and landside improvements needed to accommodate the successful establishment of an overnight, express air cargo facility (FedEx Mid-Atlantic Hub). Alternative W2-A, evaluated within this DEIS, is the proposed project that the PTAA submitted to the FAA for review. However, the PTAA acknowledges that other reasonable alternatives that fulfill the purpose and need for the proposed project may result in less environmental \\clnt01\wp_wpro\PIEDMONT\DEIS\Exsum\tnl exs.doc\03/27/00 S-20 Summary impact. Therefore, the PTAA has determined that it will wait until it has had an opportunity to review the findings of the DEIS before it identifies its preferred alternative. At the Draft stage in the EIS process, the FAA has not identified its preferred alternative(s) for the proposed project. The FAA's selection of a preferred alternative will be included in the Final EIS (FEIS) document, after the agency has had an opportunity to complete full disclosure and analysis of impacts, and interested agency representatives and the public have been afforded an opportunity to review and comment on the DEIS findings. AFFECTED ENVIRONMENT A comprehensive inventory of the existing natural, physical and social environmental conditions within the DEIS study areas was performed and is contained in Chapter 4.0 of the DEIS. The inventory and evaluation of the existing environment provided the groundwork necessary to determine the potential impacts of the airport development which were accomplished as part of the environmental consequences analysis. ENVIRONMENTAL CONSEQUENCES A detailed environmental analysis of the potential environmental impacts resulting from the construction: and operation of the No-Action Alternative and the five Build Alternatives (W2-A, W3-A, N-D, W1-A1 and N-E) was accomplished by the FAA as part of the DEIS. Two study periods were examined, 2005 (Phase 1) and 2019 (Phase 2). The year 2005 is projected to be the first year that the proposed new runway, air cargo facility and associated developments would be fully operational. The year 2019 is the outside planning period for which PTIA has FAA approved forecasts of aircraft operational activity. The potential impacts of the alternatives associated with each environmental impact category are summarized in the following overview of impacts. Detailed discussions regarding the specific analyses and findings are contained in Chapter 5.0, Environmental Consequences, of the DEIS. Mitigation measures for all applicable impact categories are consolidated in Chapter 6.0, Mitigation, of the DEIS. NOISE Development of a new runway or extension of an existing runway at an airport generally increases the area around the airport exposed to aircraft noise. Nonetheless, depending on the locations of people in the airport vicinity, new development can decrease the noise impacts from the airport. Because of the population distribution around PTIA the existing primary use of Runway 5/23 produces a lower noise impact than similar use of Runway 14/32 would. Further, the alternatives that include addition of a new runway parallel to the existing primary runway produce similar noise impacts overall. The noise impacts of Alternative N-D or WE are significantly greater than those of the other three Build Alternatives. Among the three other Build Alternatives with a new Runway 5U23R (W2-A, W3-A, and W1-A1), the least noise impact to households and population would come from Alternative W2-A. However, all of the alternatives would result in exceedances of the FAA's "Threshold of Significance", and mitigation would be considered. W.\PIEDMON'nDEIS\Exsum\fnl_exs.doc\03/23/00 S-21 Summary All development alternatives have similar nighttime operating procedures: arrivals are generally toward the proposed air cargo sorting and distribution (Fed Ex) facility and departures are generally away from that facility. Based on historic weather patterns, this operating regime would be available 95 percent of the time. The remaining time would require use of a single direction for operation- with landings and departures in the same direction as occurs now on a 24-hour basis. The noise impacts with the anticipated nighttime operating scenario are less than would occur if the nighttime operating scenario were like the current operating scenario. The potential impact of all build alternatives can be reduced (mitigated) modestly in areas near the new runway during the initial years of operation by reducing the percentage of air cargo (FedEx) operations on the new runway by 25 percent. The benefit of this change is modest, not more than 1 dB reduction in exposure level in some areas. The benefit for the areas near the new runway comes at the expense of similar increases in exposure in areas near the existing runway. Because of the distribution of population around the airport there is a net benefit in reduced exposed population with this measure. For this reason, the measure was incorporated in the mitigation plan for Phase 1. As air cargo operations increase, there would be a need to use the runways equally and the mitigation benefits would cease. The measure was not used in Phase 2. Means to mitigate adverse noise and the resultant land use impacts are presented in Chapter 6.0, Mitigation, of this DEIS. LAND USE Although most development would occur on existing airport property, all of the alternatives would result in off-airport land use impacts. Approximately 13.66 acres of property acquisition would be required for the No-Action Alternative. The land use impacts associated with the No-Action Alternative would include 141.2 acres of residential land use, and 75 homes and one noise-sensitive site. In addition, the No- Action Alternative would result in adverse impacts to 9.8 acres of wetlands and 23.1 acres of 100-year floodplains. Approximately 88.37 acres of property acquisition would be required for Alternative W2-A. The total land use impacts would include 472.1 acres of single-family residential land use, 251 homes, and one noise- sensitive site. In addition, Alternative W2-A would result in adverse impacts to 32.3 acres of wetlands and 36.6 acres of 100-year floodplains. Approximately 89.89 acres of property acquisition would be required for Alternative W3-A. The total land use impacts would include 496.0 acres of single-family residential land use, 272 homes, and one noise- sensitive site. In addition, Alternative W3-A would result in adverse impacts to 29.8 acres of wetlands and 34.6 acres of 100-year floodplains. Approximately 315.01 acres of property acquisition would be required for the construction of the Alternative N-D. The total land use impacts would include 1,143.3 acres of single-family residential land use, 1.9 acres of mobile homes, 265.2 acres of multi-family residential land use, 3,313 households, and W.\PIEDMONT\DEIS\Exsum\fnl_exs.doc\03/27/00 S-22 Summary 10 noise-sensitive sites. In addition, Alternative N-D would result in adverse impacts to 36.7 acres of wetlands and 49.6 acres of 100-year floodplains. Approximately 154.74 acres would need to be acquired for Alternative W1-A1. The total land use impacts would include 486.2 acres of single-family residential land use, 263 homes, and one noise-sensitive site. In addition, Alternative W1-A1 would result in adverse impacts to 27.3 acres of wetlands and 25.4 acres of 100-year floodplains. Approximately 266.14 acres would need to be acquired for Alternative N-E. The total land use impacts would include 1,423.6 acres of single-family residential land use, 3.9 acres of mobile homes, 135.5 acres of multi-family residential land use, 1,933 homes, and seven noise-sensitive sites. In addition, Alternative WE would result in adverse impacts to 31.3 acres of wetlands and 46.4 acres of 100-year floodplains. None of the Build Alternatives would result in direct impacts to Section 303(c) sites, 6(f) sites, or Section 106 resources (historic and archaeological resources). Alternative N-D would result in indirect impacts to 10 Section 303(c) sites and three historic architectural resources. Alternatives W-2A, W3-A, and W1-Ai would indirectly impact one historic architectural resource. Alternative WE would result in indirect impacts to 10 Section 303(c) sites and one historic architectural resource. PTAA has provided assurance, as required under 49 U.S.C. 47107(a)(10) (Airports and Airway Safety, Capacity, Noise Improvement, and Intermodal Transportation Act of 1992) that they have taken reasonable measures to maintain land use compatibility in the airport environs. A copy of PTAA's Assurance Letter is included in Appendix J of this DEIS. SOCIAL IMPACTS AND ENVIRONMENTAL JUSTICE All of the alternatives would result in social impacts, primarily in the form of relocation of homes and businesses and the disruption of surface transportation patterns. The No-Action Alternative would result in the fewest number of relocations. Of the Build Alternatives, Alternatives N-D and WE would result in the most relocations of homes and businesses. Relocation impacts associated with Alternatives W2-A, W3-A, and W1-A1 would be similar in magnitude and significantly less than either Alternatives N-D or N- E. All relocations would comply with the provisions of the Uniform Relocation Assistance and Real Property Acquisition Policies Act of 1970. All of the alternatives would result in permanent and temporary alteration of surface transportation patterns due to the relocation of existing roads, the development of new roadways and the improvement of existing roads. The No-Action Alternative, Alternative W2-A, and Alternative W3-A would result in the least alteration of surface transportation patterns. Of the build alternatives, Alternative W1-A1 would result in the greatest alteration in surface transportation patterns due to the relocation of Bryan Boulevard. However, Alternative W1-A1 would also result in the greatest improvement to traffic flow in the area around PTIA. None of the alternatives would result in significant division or disruption of established communities, disruption of orderly planned development, or cause environmental justice impacts. Changes in employment as a result of the alternatives are discussed in detail in Section 5.4, Socioeconomic Impacts. Potential mitigation measures for social impacts have been developed and are contained in Chapter 6.0, Mitigation, of this DEIS. W:\PIEDMONT\DEIS\Exsum\fnl_exs.doc\03/27/00 S-23 Summary INDUCED SOCIOECONOMIC IMPACTS This analysis evaluated two distinct and notable areas of potential economic impact as a result of the Build Alternatives. The first is related directly to the improvements associated with the air cargo sorting and distribution facility and the Mid-Atlantic Hub and its new employment. The second addresses the long-term impacts of expanding airfreight capacity at the airport and FedEx operations and, therefore, for the region. By 2019, the total number of employed persons working directly or indirectly as the result of the Mid-Atlantic Hub operations in the Six-County Socioeconomic Study Area is projected to be 16,308 persons. This full-time equivalent employment for 2019 is expected to reach 15,479. These totals include those jobs related directly to the proposed air cargo sorting and distribution facility as well as those associated with the cargo component and possible new industries attracted to the region. This total would represent a 1.9 percent increase over the No-Action Alternative projection of 872,000 jobs in the Six-County Socioeconomic Study Area. This increase in regional employment would generate over $4.4 billion in additional wages and salaries over the 16-year period and a total value added increment of $7.5 billion. Annual wages would average $275 million with average annual value added on the order of $467 million. By 2019, the total tax contribution to the state of North Carolina would be $633 million accumulated over the 16-year study period. During the same period, the local tax revenues realized within the Six-County Socioeconomic Study Area could approach $212.5 million. By 2019, annual state tax revenues generated by new businesses and new households with the Six-County Socioeconomic Study Area could approach $67 million with local tax revenues nearing $22.5 million. As a result, the total contributions to the regional economy resulting from the Build Alternatives are expected to be consequential, both in terms of the overall employment gains as well as revenues generated as a result of that increased employment. Employment growth generated by the air cargo sorting and distribution facility and PTIA improvements would further augment population growth forecasted for the No-Action Alternative. For this DEIS, it was assumed that 90 percent of the total employment generated by the Build Alternatives and predicted for the Piedmont Triad Region would occur within the Six-County Socioeconomic Study Area. The employment generated by the Build Alternatives would create 16,308 new jobs in the Six-County Socioeconomic Study Area by 2019. This induced employment would result in 10,872 new households within the Six-County Socioeconomic Study Area by 2019. The induced population for the Build Alternatives would range from 7,037 persons in 2006 to 16,109 persons in 2010 to 25,006 persons in 2019. The Six-County Socioeconomic Study Area population for the Build Alternatives would range from 1,231,179 persons in 2006 to 1,276,004 persons in 2010 to 1,357,025 persons in 2019. AIR QUALITY PTIA is located in Guilford County, North Carolina, which is designated as an "attainment" area for all U.S. Environmental Protection Agency (EPA) criteria air pollutants, with the exception of ozone, for which it is currently designated as a "maintenance" area. This designation is expected to be upgraded to attainment in the year 2003. When compared to existing conditions, air emissions associated with PTIA from aircraft, ground support equipment, and motor vehicles are expected to increase somewhat in the W:\PIEDMONT\DEIS\Exsum\fnLexs.doc\03/27/00 S-24 Summary future, with or without the proposed project. This is largely attributable to projected population and economic growth in the Greensboro area and is reflected in increased aircraft operations at PTIA. Moreover, Alternatives W2-A, W3-A, N-D, W1-A1, and WE would all result in slightly greater increases in these future emissions when compared to the future No-Action Alternative. This is attributable to the additional aircraft operations associated with the planned air cargo sorting/distribution facility at PTIA and the small differences in aircraft taxi distances associated with the planned runway/taxiway improvements. From this analysis of future-year air quality conditions for PTIA, total emissions of nitrogen oxides (one of the precursors to ozone) associated with the alternatives are above the Clean Air Act (CAA) General Conformity "de minimis" level. Therefore, the Final EIS will include a determination of conformity with the State Implementation Plan for the Greensboro/Winston-Salem/High Point ozone maintenance area. The Final EIS will also include appropriate documentation from the State of North Carolina in support of the reasonable assurance certification required by the 1982 Airport and Airway Improvement Act. Requirements for obtaining a North Carolina Department of Environment and Natural Resources (NCDENR) Transportation Facility Permit for the preferred alternative will also be addressed. WATER QUALITY Surface waters within the Brush Creek, Horsepen Creek, and East Fork Deep River sub-basins; groundwater; water supply; and wastewater treatment for the City of Greensboro would be affected with the implementation of the No-Action Alternative and Phase 1 and Phase 2 of Alternatives W2-A, W3-A, N D, W1-Al, and N-E. Impacts to surface water quality would primarily occur from stormwater runoff during construction and operation of the new transportation facilities. Surface water impacts would be greater in the Brush Creek Sub-basin with impacts of a lesser degree occurring in the Horsepen Creek Sub-basin and the East Fork Deep River Sub-basin for Alternatives W2-A, W3-A, N-D, W1-A1, and the No-Action Alternative. The Horsepen Creek Sub-basin would be impacted the most with Alternative WE with impacts to a lesser degree occurring in the Brush Creek Sub-basin and the East Fork Deep River Sub-basin. The majority of the disturbed area during construction and the greatest amount of impervious area would be added to the Brush Creek Sub-basin with moderate amounts added to the Horsepen Creek Sub-basin for Alternatives W2-A, W3-A, N-D, W1-A1, and the No-Action Alternative. The majority of the disturbed area during construction and the greatest amount of impervious area, would be added to the Horsepen Creek Sub- basin with moderate amounts added to the Brush Creek Sub-basin for Alternative N-E. The least impact would occur within the East Fork Deep River Sub-basin for all five build alternatives and the No-Action Alternative. Short-term impacts from stormwater runoff from cleared areas void of vegetation during construction could result in temporary increases in turbidity within surface waters of all three sub-basins. However, Best Management Practices (BMPs) would be implemented during construction to minimize erosion and sediment transport into surface waters. Some of the permanent BMPs implemented to minimize long-term impacts would include stormwater detention ponds, oil water separators, deicing storage tanks, and spill prevention. Groundwater discharge areas within the Brush Creek floodplain would be covered with additional impervious surfaces as a result of implementation of Alternatives W1-A1, W2-A, W3-A, and the No-Action \\clnt0l\wp_wpro\PIEDMONT\DEIS\Exsum\tnl exs.doc\03/27/00 5-25 Summary Alternative. Alternative W1-Ai Phase 1 would have the greatest amount (approximately 17 acres) of new impervious surface encroaching on groundwater discharge sites. Of the Build Alternatives, Alternatives W2-A Phase 1 and W3-A Phase 1 would have the least (approximately nine acres) new impervious surface encroaching on groundwater discharge sites. The No-Action Alternative would have approximately two acres of impervious surface encroaching on groundwater discharge sites. This should not result in a significant decrease in base flow within Brush Creek. Groundwater impacts within the East Fork Sub-basin are not expected. No groundwater discharge sites would be encroached upon in Phase 1 of Alternatives N-D and WE or Phase 2 of all five Build Alternatives. Potable water and wastewater treatment demands are expected to be the same for all of the Build Alternatives in each phase of development. The proposed air cargo sorting and distribution facility and expected increases in air traffic from commercial carriers would result in an increase in potable water demand to approximately 0.093 and 0.145 million gallons per day (MGD) for Alternatives W2-A, W3-A, N- D, W 1-A1, and WE after Phase 1 and Phase 2, respectively. This would be an increase of approximately 69 and 77 percent when compared to the No-Action Alternative and approximately 0.23 and 0.33 percent of the City of Greensboro's expected total water demand in Phase 1 and Phase 2, respectively. Increases in water supply demand for the No-Action Alternative are a result of expected increases in commercial air traffic only. Wastewater treatment demands are expected to be equivalent to the Phase 1 and Phase 2 potable water demands. Mitigation measures for water quality impacts have been developed and are discussed in Chapter 6.0, Mitigation. DEPARTMENT OF TRANSPORTATION SECTION 303(0) AND DEPARTMENT OF INTERIOR SECTION 6(F) An inventory of the DEIS Generalized and Detailed Study Areas was conducted to determine if any Department of Transportation Section 303(c) or Department of Interior Section 6(f) sites would be directly or indirectly impacted by the alternatives. A total of 63 public park and recreation sites that are designated Section 303(c) sites were identified. No Section 6(f) sites were identified within the study areas. The results of the analysis indicate that none of the alternatives in Phase 1 or Phase 2 would result in direct impacts to non-historic Section 303(c) resources. However, Alternatives N-D and WE would indirectly affect 10 non-historic Section 303(c) resources through a combination of noise, access, visual, and user population/demographics impacts. All five Build Alternatives have the potential to indirectly affect National-Register-listed historic sites, which could require additional analysis, documentation, and mitigation to comply with Section 106 of the National Historic Preservation Act. WAPIEDM0NT\DEIS\Exsum\fn1 _exs.doc\03/27/00 S-26 Summary HISTORIC AND ARCHAEOLOGICAL RESOURCES The Area of Potential Effect (APE) for historic architectural resources for the DEIS falls between the current 65 DNL noise contour and the combined 65 DNL contours for each of the five Build Alternatives. It also includes property that would be physically taken by the alternatives. One resource listed in the National Register of Historic Places-the Guilford College Historic District (survey number 17 [#17])-and two resources previously determined eligible for National Register listing-New Garden Friends Cemetery (#16) and the Roy Edgerton House (#42)-fall within the APE associated with Phases 1 and 2 of Alternative N-D. Both of the resources are Noise Sensitive Areas (FAA Airport Environmental Handbook 5050.4A, 1985): the historic district has residential and educational functions and is an outdoor historic site; the house has residential functions; and the cemetery is an outdoor historic site. Both phases of Alternative N-D would greatly increase noise levels at these sites and introduce significant audible elements that would be out of character with the historic district, house, and cemetery and accordingly would have an adverse effect upon them as defined at 36 CFR 800.5 (Protection of Historic Properties). One resource listed in the National Register of Historic Places, the Shaw-Cude House (#45), and one resource previously determined eligible for National Register listing, New Garden Friends Cemetery, fall within the APE associated with Phases 1 and 2 of Alternative N-E. The Shaw-Cude House has residential functions, the cemetery is an outdoor historic site, and both are Noise Sensitive Areas (FAA Airport Environmental Handbook 5050.4A, 1985). Both phases of Alternative N-E would greatly increase noise levels at these sites and introduce significant audible elements that would be out of character with the house and cemetery and accordingly would have an adverse effect upon the house as defined at 36 CFR 800.5 (Protection of Historic Properties). Phases 1 and 2 of Alternatives W2-A, MA and W1-A1 would result in an increase within the current 65 DNL noise contour of greater than DNL 1.5 dB at the Campbell-Gray Farm (#6), which is eligible for National Register listing. The resource is no longer a farm but has a residential function and is, therefore, a Noise Sensitive Area (FAA Airport Environmental Handbook 5050.4A, 1985). The site is presently incompatible with the operation of the airport and the project-related noise levels would not increase significantly when compared to the existing conditions. Further consultation through the Section 106 process would determine if these increases are judged to be out of character with the resource and represent an effect upon the resource as defined in 36 CFR 800.5 (Protection of Historic Properties). The FAA has determined, through a study of the files of the North Carolina State Historic Preservation Office (SHPO) and new fieldwork, that no other historic architectural resources within the APE are eligible for listing in the National Register. Therefore, the Build Alternatives would have no effect upon any other standing resources. The FAA will consult with the SHPO concerning its determinations of adverse effect on the five National Register-listed (Guilford College Historic District and Shaw-Cude House) or -eligible (New Garden Friends Cemetery, Campbell-Gray Farm, and Roy Edgerton House) resources within the APE. The FAA has proposed to conduct a full archaeological survey after the completion of the DEIS but prior to the release of the FEIS, as provided by 36 CFR 800.4(b)(2) (Protection of Historic Properties). This W:\PIEDMOMIDEIS\Exsum\fnl_exs.doc\03/27/00 S-27 Summary proposal was advanced based on the extant archaeological database that can be used to adequately evaluate any potential impacts of the alternatives on National-Register-eligible archaeological sites. This proposal would also avoid unnecessary archaeological fieldwork and evaluation. The SHPO agreed with the proposal in addressing potential effects to archaeological resources resulting from the airport improvements by a letter to FAA of September 15, 1999. BIOTIC COMMUNITIES All of the alternatives (No-Action Alternative and Alternatives W2-A, W3-A, N-D, W1-Ai, and N-E) would result in impacts to biotic communities (i.e., natural vegetative communities and wildlife). Primary impacts to biotic communities would be direct impacts from man-induced activities such as clearing vegetation, altering hydrology, filling wetlands, and grading for construction activities. Secondary impacts would be man-induced impacts that occur post-development (i.e., changes in plant community dominants due to alteration of hydrology). All five Build Alternatives would have similar magnitude of development; however, their impacts to specific cover types would vary. The No-Action Alternative would have the least impact overall to total land cover types (i.e., the acreage sum of all cover types: Urban and Developed Land, Recreational, Transportation, Agriculture, Cleared or Maintained Land, and Natural Vegetative Communities), Natural Vegetative Community cover types (i.e., the acreage sum of natural uplands and wetlands), natural uplands, and wetlands. Of the five Build Alternatives, Alternative W2-A would have the least impact (810.3 acres) and Alternative N-D would have the highest impact (1,244.3 acres) to total land cover types. For Natural Vegetative Community cover types, Alternative WE has the least impact (304.8 acres) and Alternative N- D has the highest impact (517.8 acres). For total uplands, Alternative WE has the least impact (273.46 acres) and Alternative N-D has the highest impact (481.0 acres). For total wetlands, Alternative W1-A1 has the least impact (27.26 acres) and Alternative N-D has the highest impact (36.7 acres). THREATENED AND ENDANGERED SPECIES The No-Action Alternative and the five Build Alternatives (W2-A, W3-A, N-D, W1-A1, and N-E) would all affect listed species habitats. The No-Action Alternative would impact the least amount of habitat (247.5 acres) when compared to the other alternatives. Of the Build Alternatives, Alternative WE would have the least impact (1,257.4 acres) and Alternative W1-A1 would have the greatest impact (2,716.2 acres) to natural vegetative communities that have the potential to support listed species. The bald eagle has a "moderate potential of occurrence" in the area affected by all of the alternatives since it has been documented within five miles of the Detailed Study Area. Michaux's sumac has not been, documented in Guilford County, but it was ranked as having a "moderate potential of occurrence", due to occurrence in nearby counties and existence of preferred habitat in the Detailed Study Area. Field reconnaissance of the areas affected by each of the alternatives was conducted as part of this DEIS. Neither the bald eagle nor Michaux's sumac was observed within the Detailed Study Area. Based on this analysis, implementation of any of the alternatives is not anticipated to result in significant impacts to protected species, and mitigation is not warranted. W:\PIEDMONMEIS\Exsum\fnl_exs.doc\03/27/00 S-28 Summary WETLANDS All of the alternatives (No-Action, W2-A, W3-A, N-D, W1-A1, and N-E) would result in primary and secondary impacts to wetlands that are located within and adjacent to the limits of construction. Primary impacts to wetlands would include filling, erosion, sedimentation, alterations in hydrology, and clearing of vegetation. Secondary impacts would potentially result from alterations in hydrology. Alterations in hydrology can change the dominant plant species composition and enable invasive species to become established. The No-Action, W2-A, W3-A, N-D, W1-A1, and N-E Alternatives would impact 9.8, 32.3, 29.8, 36.7, 27.3, and 31.3 acres of wetlands, respectively. The PTAA has initiated Section 404/401 coordination with the USACE and the State of North Carolina to obtain the required permits and implement a mitigation program for impacts to wetlands associated with the preferred alternative. Measures to mitigate unavoidable wetland impacts are discussed in Chapter 6.0, Mitigation, of this DEIS. FLOODPLAINS A floodplain evaluation was conducted to determine the effect of the proposed alternatives on floodplains. The results indicate that the five Build Alternatives (W2-A, W3-A, N-D, W1-A1, and N-E) would result in additional development within the 100-year floodplain. Surface transportation improvements in the No- Action Alternative would impact the 100-year floodplain as well. The total areas of the 100-year floodplain encroached upon by the alternatives would be approximately 23.1 acres with the No-Action Alternative, 36.6 acres with Alternative W2-A, 34.6 acres with Alternative W3-A, 49.6 acres with Alternative N-D, 25.4 acres with Alternative W II-All, and 46.4 acres with Alternative N-E. The majority of the encroachment would occur within the Brush Creek 100-year floodplain for the No-Action Alternative and Phase 1 of Alternatives W2-A, W3-A, N-D, W1-A1, and N-E. Approximately 3.8 acres of the Brush Creek floodplain would be encroached upon by Alternatives W2-A and W3-A, and 4 acres for Alternative W1-A1 from Phase 2 development. No encroachment onto the 100-year floodplain would occur in Phase 2 for Alternatives N-D and N-E. The only alternatives that encroach on the Horsepen Creek 100-year floodplain (approximately 4 acres) are Alternatives N-D and N-E, Phase 1. Mitigation measures would be required for all of the alternatives, because each would result in floodplain encroachment and increased runoff volumes. Mitigation measures to minimize the floodplain impacts can be accomplished for each alternative so that floodplain impacts would not be considered significant. Measures to mitigate impacts have been identified and are contained in Chapter 6.0, Mitigation, of this DEIS. COASTAL ZONE MANAGEMENT PROGRAM AND COASTAL BARRIERS None of the alternatives at PTIA would affect or involve coastal zones or coastal barrier resources. PTIA is not located in a coastal zone county. Therefore, it is not included in the Coastal Zone Management Program, and development of the No-Action Alternative or any of the Build Alternatives would not impact coastal resources. In addition, PTIA is located inland, and development of any of the Build Alternatives \\clnt01\wp_wpro\PIEDMONTDEIS\Exsum\fnl_exs.doc\03/27/00 S-29 Summary would not impact any areas designated as coastal barriers as identified in the Coastal Barrier Resource Act. Because none of the alternatives would result in impacts, mitigation measures are not warranted. WILD AND SCENIC RIVERS The Wild and Scenic Rivers Act of 1968 provides for the protection and preservation of certain rivers and their immediate environments which possess outstandingly remarkable recreational, geological, fish and wildlife, historical, cultural, and other similar values. The Act restricts development within 1,000 feet of rivers designated with the "Wild and Scenic" classification. No rivers within the Generalized and Detailed Study Areas are designated as "Wild and Scenic"; therefore, implementation of the No-Action Alternative or any of the Build Alternatives would not result in impacts to Wild and Scenic Rivers, and mitigation measures are not warranted. FARMLANDS Implementation of Alternatives W2-A, W3-A, N-D, W1-A1, and WE would all result in impacts to prime or state significant soil types as designated by the U.S. Department of Agriculture, Natural Resources Conservation Service (NRCS). Alternatives W2-A and W3-A would impact 2.1 acres each, Alternative N- D would impact 5.9 acres, Alternative W1-A1 would impact 9.8 acres, and Alternative WE would impact 6.1 acres. However, none of the alternatives would result in impacts to active prime or unique farmlands. Although some soils of prime and state significant designation would be displaced, the NRCS concluded that these areas are not actively farmed and are afforded a low protection priority; therefore, the impacts are not considered significant. Since none of the alternatives would result in significant impacts, mitigation measures are not warranted. ENERGY SUPPLY AND NATURAL RESOURCES Fuel consumption during a landing-and-takeoff cycle (LTO) is based on the power settings of the engine and time spent in each mode (i.e., approach, taxi/idle, takeoff, and climbout), as well as the number of engines for each aircraft. The two types of fuel that are dispensed at PTIA are Avgas and Jet A, with current (1998) dispensations amounting to 1,003 and 144,381 kiloliters per year, respectively. In general, fuel consumption would increase in the future with or without the proposed project because of forecasted growth in operations at PTIA. Although fuel use would increase with all of the Build Alternatives when compared to the No-Action Alternative, this increase would not result in significant impacts. Demand for electrical energy would increase with the implementation of any of the Build Alternatives. Local suppliers have indicated that this demand can be met without resulting in significant impacts to electrical generating capabilities. There are no known sources of mineral or energy resources in the Detailed Study Area that would be impacted by either the No-Action Alternative or Alternatives W2-A, W3-A, N-D, W1-A1, and N-E. Development of any of these alternatives would not require the use of unusual materials or those that are in short supply in the Greensboro area. Since none of the alternatives would result in significant energy supply or natural resource impacts, mitigation is not required. \\clnt0l\wp_wpro\PIEDMOMIDEIS\Exsum\fnl_exs.doc\03/27/00 S-30 Summary LIGHT EMISSIONS An evaluation of aviation-related, surface transportation and air cargo facility lighting systems associated with the alternatives was conducted to determine potential adverse light emission impacts to sensitive areas. Future light emission levels from airborne aircraft or aircraft operating on the ground are not anticipated to adversely impact surrounding residential areas. Light emissions from the surface transportation projects associated with the No-Action Alternative and the airfield, landside and surface transportation improvements associated with Alternatives W2-A, W3-A, N-D, W1-A1, and WE would all result in minor light emission impacts. However, through shielding and screening techniques, light emission impacts would be minimized on surrounding residential areas. These measures are discussed in Chapter 6.0, Mitigation, of this DEIS. SOLID WASTE The No-Action Alternative and Alternatives W2-A, W3-A, N-D, W1-A1, and N-E were evaluated for their potential to result in solid waste impacts associated with the potential for long-term generation of municipal solid waste (MSW) as a result of the operation of the air cargo sorting and distribution facility; the temporary generation of solid wastes due to demolition and construction activities; the potential for runway facilities to be operated adjacent to active landfills that accept putrifiable waste where a bird strike hazard may be present; and the airport's ability to comply with the guidelines contained in FAA Order 5200.5A, 'Waste Disposal Sites On or Near Airports." The results of the analysis indicate that all alternatives would result in an increase in MSW and construction and demolition waste generation at PTIA. However, these increases are not considered to be significant and would not impact the ability of the City of Greensboro to accommodate this increased demand. Alternatives W2-A, W3-A, N-D, W1-A1, and N-E would not result in an increased bird strike potential at PTIA, and the location of the proposed runway ends would be in compliance with the guidelines provided in FAA Order 5200.5A. Since Alternatives W2-A, W3-A, N-D, W1-A1, and N-E would not result in significant solid waste impacts, mitigation measures are not warranted. CONSTRUCTION Implementation of any of the alternatives, including the No-Action Alternative, would result in temporary construction impacts on air quality, noise, water quality, traffic flow, and visual impacts. The No-Action Alternative includes a new interchange, relocation and realignment of roadways, and a reconstructed airport entrance road and would cause less disruption and impacts than the five Build Alternatives. Four of the five Build Alternatives (W2-A, W3-A, N-D, and N-E) include similar surface transportation improvement projects as the No-Action Alternative. Alternative W1-Ai includes surface transportation projects that are different from the other four Build Alternatives. In addition, all five of the Build Alternatives include the construction of a parallel runway and an air cargo sorting and distribution facility. W:\PIEDMOMIDEIS\Exsum\fnl_exs.doc\03/27/00 S-31 Summary All five Build Alternatives would have greater Phase 1 and Phase 2 construction impacts than the No- Action Alternative. Development of all of the alternatives would result in wetland and floodplain impacts. Soil erosion and sedimentation control would be required for Phase 1 of the No-Action Alternative, as well as Phases 1 and 2 of Alternatives W2-A W3-A, N-D, W1-A1, and N-E. Traffic delays, fugitive dust and increased emissions from construction vehicles, visual or aesthetic impacts, and additional noise are expected as a result of all the alternatives. These impacts would be temporary and would be minimized through the establishment and use of environmental controls, such as Best Management Practices (BMPs), and Federal, state, and local construction mitigation guidelines. All on-airport construction activities should adhere to FAA Advisory Circular 150/5370-10A, Standards for Specifying Construction of Airports and North Carolina Department of Transportation Standard Specifications for Roads and Structures. Mitigation measures for construction impacts are presented in Chapter 6.0, Mitigation, of this DEIS. HAZARDOUS SUBSTANCES AND ENVIRONMENTAL CONTAMINATION The planned locations of new Runway 5U23R and Phase 1 of the air cargo sorting and distribution facility under Alternatives W2-A, W3-A, and W1-A1 are within areas that have remained largely undeveloped and contain no reported sites of hazardous substance use or environmental contamination. The Phase 2 continuation of the parallel connector taxiway and expansion of the air cargo facility apron area under these alternatives would involve closing Underground Storage Tanks (USTs) associated with the existing PTIA rental car and air cargo facilities. However, no significant impacts are anticipated. The area designated for new Runway 14U32R under Phase 2 of Alternative N-D contains these same PTIA rental car and air cargo facilities. The planned roadway and airport access improvements scheduled for Bryan Boulevard, N. Triad Boulevard, S. Triad Boulevard, Regional Road, and Old Oak Ridge Road under the No-Action and Alternatives W2-A, W3-A, N-D, W1-Ai, and WE are not anticipated to have any significant involvement with hazardous substances or sites containing environmental contamination. However, Best Management Practices (BMPs) should be developed as a means to minimized potential impacts should they occur. BMPs that could be employed are discussed in Chapter 6.0, Mitigation. SURFACE TRANSPORTATION All of the alternatives would affect surface transportation facilities in the Detailed Study Area and result in impacts to environmental resources. The surface transportation improvements associated with the No- Action Alternative would generally improve the overall transportation system in the vicinity of PTIA and would result in impacts to 40.5 acres of upland biotic communities, 9.8 acres of wetlands, and 23.1 acres of 100-year floodplains. Alternatives W2-A and W3-A would consist of the same surface transportation improvements as the No-Action Alternative, with the addition of a tunnel to carry Bryan Boulevard under \\clnt01\wp_wpro\PIEDMONl1DEIS\Exsum\fnl exs.doc\03/27/00 S-32 Summary the proposed parallel runway and two bridges over Bryan Boulevard for the parallel runway taxiway connectors. Surface transportation improvements associated with Alternatives W2-A and W3-A would improve the overall transportation system in the vicinity of PTIA and would result in impacts to 40.5 acres of upland biotic communities, 9.8 acres of wetlands, and 23.1 acres of 100-year floodplains. Alternative N-D would result in impacts to 45.1 acres of upland biotic communities, 9.8 acres of wetlands, and 23.1 acres of 100-year floodplains. Alternative W1-A1 would have the greatest effect on the local PTIA roadway system because it involves the relocation of a portion of Bryan Boulevard and the development of a new interchange at Bryan Boulevard and proposed Airport Road. This alternative would result in the greatest improvement to the overall transportation system in the vicinity of PTIA and would result in impacts to 105.4 acres of upland biotic communities, 7.1 acres of wetlands, 9.1 acres of 100-year floodplains, and require the relocation of 36 households (84 people). Alternative WE would result in impacts to 45.1 acres of upland biotic communities, 9.8 acres of wetlands, and 23.1 acres of 100-year floodplains. Impacts associated with the surface transportation improvements have been cumulatively assessed with the proposed airport improvement projects, and mitigation measures for individual impact categories are presented in Chapter 6.0, Mitigation, of this DEIS. OTHER CONSIDERATIONS CONSISTENCY WITH PLANS, GOALS AND POLICIES Alternatives W2-A, W3-A, N-D, W1-A1, and WE do not conflict with the objectives of Federal, regional, state, or local land use plans, policies, or controls for the Greensboro area. Piedmont Triad International Airport is an unincorporated entity of Guilford County, and most of the airside, landside, and surface transportation improvements would be constructed on land owned by the PTAA. Chapter 818 of the 1985 Session Laws of the North Carolina General Assembly exempts the airport property within its state- defined perimeter from annexation. Based on past practice, Guilford County would rescind its zoning authority over county properties acquired by the PTAA as a result of implementation of any of the alternatives. In that instance, the City of Greensboro and the PTAA would petition the North Carolina General Assembly to revise the airport annexation exemption boundary established in 1985 to include the acquired parcels. Local governments are supportive of the proposed project and are striving to ensure that the potential acquisition of properties and conversion to the airport use would be consistent with local land use planning and zoning. INCONSISTENCY WITH LOCAL PLANS AND LAWS All of the build alternatives are consistent with the existing Airport Layout Plan and the intent of local municipal planners. Guilford County, the PTAA, and the cities of High Point and Greensboro adopted the Airport Area Land Use Plan in 1986. This 14-year-old plan is now being updated and is scheduled for completion by January 2001. The revised plan would recommend a development pattern for the airport area that would be compatible with proposed airport improvements and would mitigate the impact of these improvements to the surrounding area. The preferred alternative resulting from the environmental review process would need to be incorporated into the revised Airport Area Land Use Plan before its adoption. \\clnt0l\wp_wpro\PIEDMONIIDEIS\Exsum\fnl_exs.doc\03/27/00 S-33 Summary DEGREE OF CONTROVERSY To date, there has been local controversy concerning the implementation of the proposed project. This controversy has been centered on the potential environmental impacts associated with the development of a parallel runway and the establishment of an air cargo sorting and distribution facility (Mid-Atlantic Hub) at PTIA, particularly with regard to noise, air quality, water quality, and quality of life issues. Many of these concerns have been voiced by the communities closest to PTIA. However, much of the larger Triad area appears supportive of the proposed development due to its potential positive economic impacts. DESIGN, ART, ARCHITECTURE FAA guidelines (5050.4A) state that design factors should be employed that would complement and support establishment of functional, efficient, and safe airport facilities while reflecting local, cultural, and architectural heritage considerations. The proposed air cargo sorting and distribution facility and runway and associated taxiways would be designed in accordance with state building codes and FAA requirements, respectively. Although no specific design plans are currently available, the PTAA would encourage the proposed air cargo sorting and distribution facility to be designed in a manner that is compatible with the existing airport environs. Landscaping would be accomplished with native vegetation and the inclusion of architectural treatments such as coloring of structural elements, buffer areas, and screening landscaping into the development's design would minimize the visual impacts of the proposed sorting and distribution facility associated with each of the alternatives. All of the proposed alternatives would create a temporary visual disturbance during construction and long- term impacts to the visual aesthetic integrity of the area. Airside improvements associated with Alternatives W2-A and W3-A would visually impact persons traveling along Old Oak Ridge Road and Lebanon Road. Residential areas located adjacent to the south end of proposed Runway 5L would experience visual impacts due to clearing of existing vegetation to established runway safety areas. Alternatives N-D and WE would visually impact persons traveling along Ballinger Road. Alternative W1-A1 would result in visual impacts to residential areas south and west of PTIA. FAA requirements dictate specific operational areas that must be cleared and maintained for aviation safety purposes. Few measures to mitigate an airfield's visual impact can be accomplished. However, PTAA would work with the local communities to minimize visual impacts to the extent possible while not compromising aviation safety. Landside improvements associated with all of the Build Alternatives would impact the aesthetic integrity of the area; however, vegetation and design factors would be employed to complement the proposed air cargo facility. CUMULATIVE IMPACTS In accordance with the Council on Environmental Quality (CEQ) guidelines, the DEIS was prepared to consider the overall cumulative impact of the proposed project and the consequences of subsequent related actions. According to CEQ, cumulative impacts represent the "impact on the environment which results from the incremental impact of the action when added to other past, present, and reasonably \\clnt0l\wp_wpro\PIEDMONTDEIS\Exsum\fnl_exs.doc\03/27/00 S-34 Summary foreseeable future actions, regardless of what agency (Federal or non-Federal) or person undertakes such other actions. Cumulative impacts can result from individual minor but collectively significant actions taking place over a period of time." The DEIS has and does take into consideration cumulative impacts that could result. The study considered, to the extent reasonable and practical, the possible impacts of the proposed project and other developments, both on and off the airport which are related in terms of time or proximity. The FAA's DEIS considers those improvements proposed in the 1994 Master Plan and depicted on the PTIA ALP that are considered "ripe" for evaluation. Although there are many individual improvements proposed, only a few represent most of the work, cost, and potential for impact. The proposed airport development actions were consolidated into the following five major development categories: • New runway and associated taxiway system, • Overnight express air cargo sorting and distribution facility, • Surface transportation improvements, • Property acquisition, and • Relocation of on-airport facilities. The DEIS highlights these major projects and their alternatives and evaluates them both individually and cumulatively. Many of the other proposed improvement recommendations were evaluated cumulatively as "connected actions" to the major development actions. Many of these actions would not normally require environmental analysis on an individual basis. The DEIS also considers the cumulative impacts of other (FAA and non-FAA) actions together with the proposed improvements at PTIA to the extent reasonable. Developments not connected to the DEIS include the Categorical Exclusion for the Runway 14 Safety Area for PTIA (dated: May 7, 1998) and the FEIS for the Greensboro Western Urban Loop (dated: February 28, 1995). Coordination with the cities of Greensboro, High Point, and Winston-Salem as well as Guilford County indicate that there are no other known major planned developments in the PTIA area that need to be considered on a cumulative basis. UNAVOIDABLE ADVERSE IMPACTS AND IRREVERSIBLE AND IRRETRIEVABLE COMMITMENT OF RESOURCES The construction and operation of the proposed improvements would result in the use of resources and environmental impacts that are unavoidable. The impacts associated with the proposed improvements are disclosed for specific impact categories in Sections 5.1 through 5.22 of the DEIS. Proposed mitigation concepts for impacts associated with those categories significantly affected by the alternatives are summarized in Chapter 6.0, Mitigation. \\clnt01\wp_wpro\PIEDMOMIDEIS\ExsumVnl_exs.doc\03/27/00 S-35 Summary MAN'S RELATIONSHIP BETWEEN LOCAL SHORT-TERM USES OF HIS ENVIRONMENT AND MAINTENANCE AND ENHANCEMENT OF LONG-TERM PRODUCTIVITY All of the reasonable alternatives would require use of man's environment during construction to achieve the long-term goals of improved aviation capacity, economic vitality, and traffic flows. Traffic delays, fugitive dust, and increased emissions from construction vehicles; visual and aesthetic impacts; and additional construction noise are expected as a result of all the alternatives. These impacts would be short-term in nature, and temporary, and would be minimized through the establishment and use of environmental controls, such as Best Management Practices (BMPs) and Federal, state, and local construction mitigation guidelines. Refer to DEIS Section 5.19, Construction Impacts, for additional information associated with short-term use of man's environment and DEIS Section 6.2.8, Possible Construction Impacts Mitigation Measures, for information concerning mitigation measures during construction. As discussed in Chapter 2.0, Purpose and Need, it was determined that to efficiently operate an air cargo facility at PTIA, both a widely spaced Transport-Category parallel runway and a facility located between the parallel runways are needed. These improvements would meet the short-term needs of the air cargo operator and achieve the long-term operational goals and needs of the PTIA. Long-term benefits of all of the Build Alternatives would ultimately increase air capacity for PTIA, the region, and the national airspace system. The majority of the roadways in the vicinity of PTIA are currently operating at acceptable Levels of i Service (LOS). These Levels of Service would decrease in the future as traffic volumes increase and high levels of congestion would occur in the peak travel hours. All of the alternatives would implement infrastructure projects, which would improve long-term traffic flows in the PTIA area. Refer to DEIS Appendix I for additional information concerning surface transportation improvements. MITIGATION The construction and operation of the proposed improvements would result in the use of resources and in unavoidable environmental impacts. The FAA has identified mitigation measures to minimize the adverse effects of the construction and operation of the proposed improvements. These mitigation measures, which are detailed in Chapter 6.0, Mitigation, of the DEIS, will be expanded and refined into a recommended mitigation program, to the extent applicable, in the Final EIS (FEIS) as a result of public and agency comments on the DEIS. COORDINATION AND PUBLIC INVOLVEMENT The EIS process for the proposed project at PTIA has included an extensive public involvement and coordination program. Activities accomplished as part of the DEIS include Scoping meetings (agency and public), a public workshop, media coordination, agency coordination, and the public distribution of project related information through the use of newsletters and the internet. A Public Hearing/Information Workshop to receive comments on the DEIS is planned at least 30 days after the DEIS is published for \\clnt01\wp_wpro\PIEDMONT\DEIS\Exsum\fnl_exs.doc\03/27/00 S-36 Summary review. Comments on the DEIS will be accepted by the FAA for a period of up to 45 days from the publication of the Federal Register Notice of Availability of the DEIS. FINAL EIS AND RECORD OF DECISION Comments received from the public and agencies on the DEIS will be reviewed and considered by the FAA in the preparation of the FEIS. All comments received will be summarized and responded to in the FEIS. The FAA will release the FEIS for public review and subsequently issue a formal Record of Decision (ROD) which states the agency's decision regarding the project and the agency's evaluation and analysis of the environmentally preferred alternative. It will also include any mitigation measures that were made a condition of the approval of the EIS. \\clnt01\wp_wpro\PIEDMONT\DEIS\Exsum\fnl exs.doc\03/27/00 S"37 Summary 6 � } ��.

R DRAFT ENVIRONMENTAL IMPACT STATEMENT PIEDMONT TRIAD `INTERNATIONAL AIRPORT CHAPTER 1 INTRODUCTION CHAPTER 1.0 INTRODUCTION 1.1 ABOUT THE PIEDMONT TRIAD INTERNATIONAL AIRPORT DENS The Federal Aviation Administration (FAA) prepared this Draft Environmental Impact Statement (DEIS) to identify the potential environmental effects associated with the construction and operation of proposed improvements to the Piedmont Triad International Airport (PTIA). The Piedmont Triad Airport Authority (PTAA), the owner and operator of PTIA, completed the 1994 Master Plan Update (MPU) that identified a comprehensive development program for the expansion of PTIA. (PTAA is in the process of completing a new MPU update that does not affect the current proposal for improvements to PTIA). The PTAA has submitted the new runway portion of its Airport Layout Plan (ALP) to the FAA for environmental approval in connection with its intent to seek Federal funds to implement Master Plan project implementation. The FAA must prepare an EIS and issue a Record of Decision (ROD) that reflect its approval or disapproval of the proposal under environmental criteria. The proposed improvements cannot be considered eligible for Federal funding until the FAA issues a ROD. 1.1.1 THE PROPOSED IMPROVEMENTS TO PTIA The PTAA is requesting Federal actions to implement airside and landside improvements to PTIA on the ALP that are intended to enable the airport to effectively meet estimated levels of activity associated with the operational requirements of a proposed air cargo hub. The PTAA's proposed project features a new parallel Transport Category runway, 9,000 feet long by 150 feet wide, which would be located on the western side of the airport. This runway is intended to improve airfield capacity during both visual meteorological conditions (VMC) and instrument meteorological conditions (IMC). The proposed project also includes the development of an overnight, express air cargo sorting and distribution facility, roadway improvements, NAVAIDS for new Runway 5U23R, property acquisition, and relocation of several airport tenant operations. 1.1.2 FAA's ENVIRONMENTAL RESPONSIBILITIES In recognizing the importance of protecting the environment, the U.S. Congress passed the National Environmental Policy Act of 1969 (NEPA) to encourage Federal agencies to enhance the environment. NEPA requires Federal agencies to treat environmental impact as a primary criterion in evaluating a proposed project. It also requires Federal agencies to analyze and consider alternatives to, and the environmental impacts of, their proposed actions, to disclose and consider mitigation for those impacts, and to provide interested parties with an opportunity to participate in the environmental review process. In addition, Federal agencies must consider the "No-Action" Alternative. Furthermore, NEPA requires Federal agencies to consider a proposed action's environmental consequences along with the agency's statutory mission and technical factors related to their areas of expertise. The FAA is responsible for complying with NEPA whenever an airport sponsor seeks to implement projects depicted on an ALP and associated Federal actions. The FAA has reviewed PTIA's 1994 ALP W.\PIEDMONT\DEIS\Ch_t\Ch_l.doc\03/23/00 1 -1 Chapter 1.0 Introduction and determined that an EIS would be the most appropriate document for the agency to fulfill its obligations under NEPA and FAA Orders 1050.1 D (FAA, 1986) and 5050.4A (FAA, 1985). In July 1998, the FAA published a Notice of Intent (NOI) to prepare the DEIS for the PTIA proposed expansion. Public and agency scoping meetings were held in August 1998 to receive comments regarding the scope of the analysis and identify any potential environmental impacts. In addition, a Public Information Workshop was held in April 1999 to receive any additional comments from interested parties on the scope of the analysis to be conducted during the environmental process. In Chapter 2.0, Purpose and Need, the purpose and need for the proposed project is defined. In Chapter 3.0, Alternatives, the FAA examines a range of alternatives, including the No-Action Alternative and the PTAA's proposed project, and focuses on reasonable alternatives to the proposed project, as prescribed by the Council on Environmental Quality (CEO) regulations. 1.1.3 COOPERATING AGENCY A cooperating agency is an agency that has jurisdiction by law or special expertise regarding any environmental impact resulting from a proposed project or reasonable alternative. The Federal Highway Administration (FHWA) has been invited and has agreed to participate as a cooperating agency for this DEIS, because PTAA is proposing several roadway projects in its development program that would be needed if the PTAA proposed runway and associated projects were implemented. These projects would include construction of a tunnel for Bryan Boulevard under the proposed new parallel Runway 5U23R and construction of two bridges over Bryan Boulevard for the cross-field taxiways. For NEPA analysis in this DEIS, PTAA's proposed improvement plan as well as its alternatives include these projects. These surface transportation improvement projects are under the jurisdiction of the FHWA and the North Carolina Department of Transportation (NCDOT). This DEIS contains a special technical appendix (Appendix 1) that presents separate FHWA Purpose and Need statements, Alternatives evaluation, and Environmental Consequences (impact analysis) for the surface transportation improvements. The FHWA has proposed to adopt the FAA's Final Environmental Impact Statement (FEIS) and ROD, in compliance with NEPA requirements. Specific elements of the FHWA approval actions include: FHWA approval of the Surface Transportation developments which would include interchange and arterial roadway improvements to provide increased capacity, Level of Service and safety as well as improve system linkage within the area surrounding PTIA, and FHWA Federal environmental approval necessary to proceed with the processing of an application for Federal funding for those development proposals qualifying under 42 USC 433(2)(c) and 23 CFR 771. In addition to the above described proposed surface transportation improvement projects, the PTAA is undertaking several additional roadway improvement projects which would be implemented by the PTAA \\clnt01\wp_wpro\PIEDM0MIDEIS\Ch_1\Ch_1.doc\03/23/00 1-2 Chapter 1.0 Introduction whether or not proposed Runway 5U23R and the air cargo sorting and distribution facility were developed. These independent projects include the closure and relocation of a portion of Regional Road, a new interchange at Bryan Boulevard and Old Oak Ridge Road, the relocation of a portion of Old Oak Ridge Road, reconstruction of South Triad Boulevard and construction of a new North Triad Boulevard interchange. These independent roadway improvement projects are also under the jurisdiction of the FHWA and NCDOT. This DEIS discloses the potential environmental impacts associated with these projects. However, these projects, unlike the roadway projects described in the previous paragraph, are independent of the new runway proposal and are therefore also included in the analysis of the No-Action Alternative. The FHWA proposes to adopt the FAA's FEIS and ROD for these projects as well. 1.1.4 DOCUMENT ORGANIZATION The organization of the DEIS is described below: Volume 1 - DEIS Documentation - contains the text of analysis and associated tables and exhibits of the DEIS.

WAPIEDMONT\DEIS\Ch_l\Ch_t.doc\03/23/00 1-4 Chapter 1.0 Introduction 1.2 BACKGROUND INFORMATION Over the years, the PTAA has developed numerous plans regarding the expansion of PTIA and how to best meet the aviation needs of the Triad. Although the development plan shown on the 1994 PTIA ALP (and examined in this DEIS) is the culmination of the most recent planning effort accomplished by PTAA, the proposed parallel runway and land area for cargo facility development have been depicted on the PTIA ALP in the currently proposed locations since the publication of the 1968 Master Plan. PTAA states that it will continue to depict a 10,000 foot Transport Category parallel runway on the ALP even if the FAA determines that the purpose and need for the proposed project can be met with a perpendicular runway configuration to allow them the option to construct it at some later time, if needed. 1.2.1 PROPOSED PROJECT DESCRIPTION In 1994, the PTAA approved the airport's Master Plan Update, which set forth a long-term development program to help the airport meet the air transportation needs of the Triad. Subsequent to the PTAA's approval, the FAA accepted the PTIA Master Plan and granted conditional approval of the PTIA ALP, subject to environmental review. This meant that NEPA review was not required until PTAA proposed to implement a depicted project and actually submitted a proposal to the FAA, which PTAA has now done for the parallel runway project. The ALP, which reflects the existing and future facilities on the airport, is depicted on Figure 1.2-1, and includes elements for the development of a new parallel Runway 5L/23R and the expansion of air cargo facilities in the northeast quadrant of the airport that are the subject of this EIS. The overall goals of the PTAA are to develop an airport facility that provides two widely spaced parallel runways; supporting air cargo sorting and distribution facility capable of handling 48 daily FedEx air cargo aircraft operations (24 departures) by the year 2005 and 126 daily FedEx air cargo aircraft operations (63 departures) by the year 2009; an extensive taxiway network, and well-developed surface transportation infrastructure. In order to achieve this goal, a two-phase development program has been proposed by the PTAA. Phase 1 developments, illustrated in Figure 1.2-2, consist of the following direct and connected projects that the PTAA envisions would be constructed between 2000 and 2004 and be fully operational in the year 2005: • Construction of a new parallel 9,000' by 150' Transport Category runway capable of accommodating Airplane Design Group (ADG) D-V air carrier aircraft (DC-10). The proposed airfield system complex consists of the runway and taxiway as described; parallel and connecting taxiways; lighting; navigational aids (for Category fl/III capabilities); runway safety areas and protection zones, and associated grading, drainage, and utility relocations; • Cross field extension of Taxiway D; • High Speed Exit Taxiway for existing Runway 5/23; • Construction and operation of Phase 1 (approximately 736,000 square feet) of an air cargo sorting and distribution facility (FedEx Mid-Atlantic Hub); W:\PIEDMONTDEIS\Ch_l\Ch_t.doc\03123/00 1 -5 Chapter 1.0 Introduction • Construction and operation of Phase 1 (approximately 174,000 square yards) of air cargo aircraft parking and air cargo ramp associated with the air cargo sorting and distribution facility; • Construction of a tunnel for Bryan Boulevard under the proposed runway; • Relocation of on-airport rental car service lots; • Relocation of two existing air cargo buildings; • Construction of one connector taxiway bridge and cross field taxiway over Bryan Boulevard; • Initiation of actions to obtain State Water Quality Certification Section 401 and USACE Section 404 permits and implementation of mitigation measures, and • Implementation of air traffic procedures below 3,000 feet above ground level (AGL). Other Phase 1 projects, also illustrated in Figure 1.2-2, consist of projects which would occur, according to PTAA, whether or not the proposed runway project was implemented. These projects include: • Construction of a new interchange for Old Oak Ridge Road and Bryan Boulevard; • Relocation of a portion of Old Oak Ridge Road; • Closure and relocation of a portion of Regional Road; and • Construction and operation of new airport entrance interchanges off Bryan Boulevard to the PTIA terminal area (modification of existing South Triad Boulevard and construction of a new North Triad Boulevard). Phase 2 projects are also illustrated in Figure 1.2-2. It is anticipated by the PTAA that Phase 2 of the proposed project would be constructed between the years 2005 and 2009 and be fully operational in the year 2009. The Phase 2 projects include: • Construction and operation of Phase 2 of the air cargo sorting and distribution facility (expand the Phase 1 facility by approximately 509,000 square feet): • Construction and operation of Phase 2 of the air cargo aircraft parking and air cargo ramp (expansion of the Phase 1 parking/ramp area by approximately 281,000 square yards); • Extension of the north cross field taxiway to the Phase 2 apron area, and • Construction of a second connector taxiway bridge and cross field taxiway over Bryan Boulevard. Although the proposed PTIA development program is divided into two phases of activity, this DEIS will consider the proposed project's direct and indirect impacts for all project elements within the Phase 1 and 2 development envelope. This will include the cumulative evaluation of impacts to 21 environmental categories, as discussed in Chapter 5.0, Environmental Consequences. W:\PIEDMONT\DEIS\Ch_l\Ch_l.doc\03/23/00 1-6 Chapter 1.0 Introduction ?' . 1.2.2 AIRPORT HISTORY PTIA was originally established in 1927 and has handled scheduled air and passenger service since 1928. Since the early 1930s, FAA and other PTAA projects have resulted in the present configuration of this airport. One primary and one cross wind runway and a full array of parallel and connecting taxiways are the foundation for the current airside facilities. In October 1982, a new air carrier ramp and a terminal area were completed. This allowed the PTAA to construct and then relocate the terminal facilities from its old location on the southwestern side of the airfield to a more centrally located position northwest of the main runway and centered within the current airfield operations area. Supplementing the construction of the new terminal building was the construction of maintenance facilities by Piedmont Airlines (now TIMCO), Cessna and Tradewinds. These facilities are located on the opposite side of the main runway from the new terminal building and include hangar and ramp capabilities for aircraft as large as the Boeing 757. Within the timeframe of 1980 to 1998, the following major occurrences have impacted PTIA enplanements: • Opening of Charlotte US Airways Hub -1979; • National Economic Recession -1981; • Initiation of People's Express Flights -1985; • Opening of Raleigh/Durham Hub -1987; • Suspension of People's Express Flights -1989; • National Economic Recession - 1990,1991; • Increase in Continental Daily Flights from 3 to 34 -1994; • Increase in Continental Daily Flights from 34 to 84 -1995; and • Reduction in Continental Daily Flights to 9 -1998. Dramatic air carrier operational increases occurred during 1994 and 1995 with the introduction of Continental Airline's hub services at PTIA. This hub activity was accompanied by increasing regional airline activity. Since 1995, total enplanements have declined due primarily to activity reductions by Continental Airlines and, secondarily, US Airways (PTAA, 1999). Within the timeframe of 1995 to 1997, three new airlines were introduced to PTIA (i.e., Northwest, Eastwind, and Airtran). These airlines accounted for 11.7 percent of the 1997 PTIA market share. While the total number and percentage of regional (short haul) airline activity decreased between the years 1996 and 1997, the regional activity in 1997 was still at a much higher level than 1988, i.e., 35.4 percent of operations compared to a previous 21.5 percent. \\c1MO1\wp_wpro\PIEDMONTDEIS\Ch_1\Ch_1.doc\03/23/00 1-7 Chapter 1.0 Introduction 1.2.3 AIRPORT DESCRIPTION PTIA is located approximately 10 miles west of the central business district of Greensboro, 13 miles east of Winston-Salem, and 10 miles north of High Point, North Carolina. The area is referred to as the Piedmont Triad Urban Region. Encompassing 12 counties and more than 1,340,045 people, this area of North Carolina is a major manufacturing, trade, transportation, and financial center for the state and the southeastern United States. The region's core metropolitan area, officially termed the Greensboro/Winston-Salem/High Point Metropolitan Statistical Area (MSA), is known as the Piedmont Triad. An airport location map and an airport vicinity map are provided on Figures 1.2-3 and 1.2-4, respectively. Currently, PTIA has two runways: Runway 5/23 and Runway 14/32. Runway 5/23, PTIA's primary runway, is 10,001 feet long, with runway centerline lights, a Medium Intensity Approach Lighting System with Runway Alignment Indicator Lights (MALSR) and a Visual Approach Slope Indicator System (VASI) on the Runway 5 end, and a High Intensity Approach Lighting System with Sequenced Flashing Lights, Category II (ALSF2) with Touchdown Zone Lights (TDZ) on the Runway 23 end. Runway 5 has CAT I Instrument Flight Rules (IFR) capability and Runway 23 has CAT II IFR capability. Runway 14/32, PTIA's secondary runway, is 6,380 feet long, with a MALSR on the Runway 14 end and Runway End Identifier Lights (REILs) with a VASI on the Runway 32 end and CAT I IFR capability. PTIA currently encompasses approximately 3,000 acres. 1.2.4 PT/A's ROLE PTIA is designated as a small airport hub in the region and accounts for less than 0.25 percent of total revenue passengers enplaned by U.S. flag air carriers in the United States. In 1999, the airport was served by five commercial air carriers, six regional airlines, and four air cargo airlines. 1.2.5 RECENT RELATED STUDIES AT PTIA In 1994, PTAA completed a comprehensive Master Plan study called the Piedmont Triad International Airport Master Plan Update (MPU). The study consisted of an examination of aviation forecasts, demand- capacity analysis and facility requirements. Development projects were recommended in the MPU to meet the future landside, and airside needs of PTIA. These recommendations included: • An extension of Runway 14/32 to a length of 9,000 feet; • The addition of high speed taxiways to Runway 5/23; • Land acquisition in connection with runway extensions; • The extension of Runway 5/23 to a length of 13,000 feet; • The development of a new 10,000-foot widely spaced Transport Category runway parallel to existing Runway 5/23, and W:\PIEDMON-nDEIS\Ch_l\Ch_l.doc\03/23/00 1-8 Chapter 1.0 Introduction / k. r < r ,<> fbtemation i y r ` Airport pr` -0 nab org- fns ->3 `" ?? - R6c y ?Aount', pFr ol?{t R L v? ?y? ? ? ? ? vljlle ?; WI rlfnin to ? t' Atlantic Ocean 50 0 50 Miles 0 IQ P" e: - e Legend General Features A rport Property Boundary Roads Rallroad /V Streams O Lakes 0 scalal".6000' 5000 Feet Figure PIEDMONT 1.2.4 Vicinity Map TRIAD URS Greiner Woodward Clyde INTERNATIONAL AIRPORT' Date: 11/01/99 Environmental Impact Statement The development of a new 10,000-foot widely spaced Transport Category runway parallel to existing Runway 5/23, and • Air carrier terminal/ramp expansions. The 1994 Master Plan Update was adopted by the PTAA in 1995. Of the above listed projects, only land acquisition activities have been accomplished to-date. In 1998, the PTAA initiated a study to update the 1994 Master Plan Update. It is expected that this update will be completed in mid 2000. PTAA has indicated that the new MPU update will not affect the current proposal for improvements to PTIA because PTAA is moving forward with trying to implement the proposed project. 1.3 FORECASTS OFAVIAT/ONACTIVITY Forecasts of aviation activity for PTIA were recently updated by the PTAA as part of the ongoing PTIA MPU. This effort included the development of revised Air Cargo forecasts and total operations forecasts as a result of the April 1998 announcement by FedEx and the PTAA to locate the Mid-Atlantic Hub at PTIA. The MPU forecasts were compared to the FAA's own Terminal Area Forecasts (TAF) during their development. Coordination with the FAA determined that the Master Plan forecasts were within the required 10 percent of the FAA's TAF, which is the variance level deemed acceptable by the FAA. Subsequently, the MPU forecasts presented in Tables 1.3-1 and 1.3-2 were reviewed by the FAA and determined to be reasonable and were accepted by the FAA on October 20, 1998. The FAA has since revised the PTIA TAF to incorporate the MPU forecasts resulting from the ongoing PTIA Master Plan Update. These forecasts are used throughout the DEIS in the establishment of the Purpose and Need in Chapter 2.0, the Alternatives in Chapter 3.0 and the Environmental Consequences in Chapter 5.0. The forecast assumptions are available for review at the FAA's Atlanta District Office in Atlanta, Georgia.

This chapter of the DEIS describes the Purpose and Need for the proposed project at PTIA and identifies the Federal actions requested of the FAA. The identification of a proposed project's purpose and need is the primary foundation for the identification of reasonable alternatives to the project and the evaluation of the impacts of the alternatives. The requested Federal actions being considered by the FAA in this DEIS include FAA's approval of portions of the existing 1994 ALP to accommodate the proposed expansion of PTIA as an air cargo hub, and FHWA's approval of the proposed surface transportation improvements associated with the proposed project. The 1994 ALP identifies major development items that constitute PTAA's current project proposal, including the construction of a parallel air carrier runway, air cargo facility improvements, roadway improvements, and associated developments. As a cooperating agency for this DEIS, the FHWA is responsible for reviewing the surface transportation components of the proposed project. Appendix I of this DEIS contains a technical document that identifies the Federal actions requested of the FHWA, and describes the purpose and need, alternatives and environmental consequences of the surface transportation components of the proposed project at PTIA. The nature of the proposed project at PTIA and the nature of the various requested Federal actions which are the subject of this DEIS dictate that the purpose and need for the proposed project be clearly stated and fully described. PTAA proposes expanded aviation facilities at PTIA to accommodate the operational requirements of a proposed overnight, express air cargo sorting and distribution facility (FedEx Mid- Atlantic Hub). The facilities proposed by the PTAA are a new widely spaced Transport Category parallel runway with associated taxiways and NAVAIDS and a proposed overnight express air cargo hub facility. This DEIS discloses the potential environmental impacts associated with these projects, their reasonable alternatives, and other cumulative actions in Chapter 5.0, Environmental Consequences. Based on FAA planning guidelines contained in FAA Advisory Circular 5090.313, Field Formulation of the National Plan of Integrated Airport Systems, Table 3-2 (FAA, September 1985), planning for runway capacity improvements at PTIA, which might support the need for an additional runway, could conceivably be needed in the year 2001, in anticipation of long-term capacity needs of PTIA starting in the year 2015, without the introduction of the overnight, express air cargo carrier. That possibility, however, is beyond the scope of this EIS. This EIS is limited to considering the project request submitted by the PTAA, and the scoping process itself, to considering airside improvements that would accommodate an overnight express air cargo carrier beginning in the year 2004. The following sections of this Chapter present the purpose for the proposed improvements at PTIA and describes why the proposed improvements are needed. \\clnt0l\wp_wpro\PIEDMONT\DEIS\Ch_2\Ch_2.doc\03/23/00 2-1 Chapter 2.0 Purpose and Need 2.2 PURPOSE AND NEED FOR THE PROPOSED IMPROVEMENTS 2.2.1 INTRODUCTION The PTAA has been approached by an overnight, express air cargo operator (FedEx) which, after a detailed evaluation of potential locations, has selected PTIA as the site for establishment of a new hub to serve it's eastern United States market. PTAA, in turn, wishes to develop an air cargo hub at PTIA, and has requested that the FAA take the necessary Federal actions to implement the proposed development of a parallel runway and associated projects at PTIA. One of the missions of the PTAA is to support the growth and development of PTIA such that the airport is capable of accommodating the air transportation needs of the Triad. It is also a mission of the PTAA to continue to allow PTIA to be a major employment center and economic generator in the Triad. Development of an overnight air cargo hub at PTIA would facilitate PTAA's meeting their stated mission. Likewise, the FAA has a statutory authority to both §upport and promote national transportation policies, and to respond to project-specific needs for aviation development. The immediate action required of the FAA is the processing of a draft and final EIS, and the issuance of an environmental finding in a ROD. 2.2.2 PURPOSE FOR THE PROPOSED IMPROVEMENTS 2.2.2.1 Consistency With Federal Transportation Policies The FAA is charged with the implementation of Federal policies under its statutory authorities. The National Transportation Policy was established by §502(b) of the 1990 amendments to the Airport and Airway Improvement Act of 1982 and is codified at 49 U.S.C. § 47101(b). It is within the framework of NEPA and the Airport and Airway Improvement Act, as amended, that the FAA is responding to the PTAA's proposal. The language of 49 U.S.C. § 40101(b) further directs the Secretary of Transportation to consider the following to be in the public interest in regard to air cargo transportation: (1) Encouraging and developing an expedited all-cargo air transportation system provided by private enterprise and responsive to: (A) The present and future needs of shippers; (B) The commerce of the United States; (C) The national defense. (2) Encouraging and developing an integrated transportation system relying on competitive market forces to decide the extent, variety, quality, and price of services provided. (3) Providing services without unreasonable discrimination, unfair or deceptive practices, or predatory pricing. W:\PIEDMONT\DEIS\Ch 2\Ch_2.doc\03/24/00 2-2 Chapter 2.0 Purpose and Need The potential development of an overnight, express air cargo hub at PTIA is consistent with FAA's responsibility to support locally-sponsored projects that fulfill the above referenced public policy objectives. 2.2.2.2 Develop an Air Cargo Sorting and Distribution Facility Demand for the air cargo hub at PTIA is driven by existing and projected demand for express overnight air cargo movements within the eastern United States. The development of such a facility at PTIA is congruent with that of the PTAA's stated interest in on-going airport development and expansion to meet the air service needs of the Triad and to be a major economic generator. The decision to site an overnight air cargo hub anywhere in the U.S., including at PTIA, is a decision reserved to the private sector and to local authorities (i.e., other than evaluation of proposals under NEPA, the FAA lacks statutory authority to participate in airport site selection for private aviation entities). PTAA states that its proposal is based on its plan to efficiently accommodate existing and projected aviation demand at PTIA. The development of an overnight, express air cargo hub at PTIA responds to industry and PTAA expectation that traditional air cargo traffic is increasing and, most importantly, that overnight express air cargo demand will continue to increase. PTAA states that in the overnight express air cargo business, time is the commodity being sold when transporting parcels from the point of pickup to the final point of delivery within pre-defined time periods. The industry standard and competitive express delivery market demands have reduced the timeframe for transportation, processing, and delivery of overnight packages to a period from 7:00 p.m. to 10:30 a.m. the following day. FedEx states that alterations, delays, or unexpected changes in any single system element (arrival, sorting, or departure) within the allotted time can create a detrimental ripple effect that can cause down-line distribution centers in many destination cities to miss guaranteed delivery times. Within the FedEx national system, as described by FedEx, each existing air hub (e.g., Memphis, Indianapolis, Fort Worth) receives, sorts, and consolidates parcels for redistribution to other airport destinations within an established timeframe called the "sort". To provide guaranteed on time package service, FedEx has established designated minimum departure times for aircraft operating at its various hubs referred to as the "push-back-to-wheels-up" times. During this period, each cargo aircraft departure sequence (i.e., push back from gate, ground taxi, and runway departure) must be conducted within a pre- defined window of time to assure aircraft arrival at their assigned destinations at pre-established times while also meeting guaranteed overnight delivery schedules. The push-back-to-wheels-up time ranges from five to fifteen minutes, and varies by aircraft type. The importance of successfully meeting the push-back-to-wheels-up time is critical to FedEx. A single aircraft delayed at the gate, while in ground taxi to or from the gate or delayed because of runway capacity and/or sequencing delay can cause as many as 10,000 packages or letters to be delayed. As represented by FedEx, when the push-back-to-wheels-up times are exceeded, on-time delivery schedules cannot be met and the overall costs of providing the overnight express delivery service are increased. \\c1nt01\wp_wpro\PIEDMONnDEIS\Ch_2\Ch_2.doc\03/23/00 2-3 Chapter 2.0 Purpose and Need PTAA's proposed improvements were designed to support the development of an overnight, express air cargo hub at PTIA and to provide airside, landside and surface transportation facilities that allow both the airport and the hub to be operated in an efficient manner. The PTAA has indicated to the FAA that the selection of the placement of the overnight cargo hub in either North Carolina or South Carolina was based on a business decision made by FedEx. As represented to the FAA by PTAA and FedEx, the location of the hub within these two states was based on several considerations including the following: • The hub had to be located on the East Coast of the United States to serve the projected market area; • The hub had to be sited so that its market service area was located within a single time- zone; • The hub had to be centrally located within the projected East Coast market area, and • The hub had to be located in an area of moderate weather patterns to reduce the likelihood of interruption of service due to inclement weather conditions. After selecting the general geographic location for the hub, FedEx issued a Request for Proposals (RFP) in November, 1997 to air carrier certificated airports within the two-state area. Those airports that had an interest in the development of the overnight air cargo hub responded to the RFP with detailed proposals describing how the individual airport could accommodate the hub facility requirements. Between February, 1998 and April, 1998, FedEx undertook a detailed evaluation of each of the proposals as part of its site selection study. According to FedEx, the site selection study evaluated numerous criteria at each airport including the following: • Airport Operations - Runway Configuration, Runway Lengths, Instrument Approaches, Airfield Capacity, Runway Accessibility, Airspace and Air Traffic Control (ATC) Constraints, FAA and Radar Availability, Noise and Operational Concerns, Weather History, and Aircraft Rescue and Fire Fighting Availability. • Site Selection - Site Layout, Topography, Environmental Constraints, Site Access, Utilities, Airport Services Provided, Construction Restrictions, and Responses to the Request for Proposals. • Financial Analysis - System Form Expenses, Properties and Facilities Expenses, Salaries and Benefits, Taxes and Incentives. FedEx selected PTIA in April, 1998 for the site of its hub because PTIA was the top-rated airport in the following selection criteria. According to FedEx, none of the other airports was as competitive with PTIA in all of these criteria • Space required for the development of the size of the facility and aircraft apron proposed by FedEx; • Attractive low land lease rate; • Ability to develop parallel runways; • Ideal proposed hub site location between existing and future parallel runways; \\clnt01\wp_wpro\PIEDMONrDEIS\Ch_2\Ch_2.doc\03/23/00 2-4 Chapter 2.0 Purpose and Need • Ability to operate head-to-head aircraft operations (from and to the same direction), thereby reducing taxi times; No competition for runway use during hub arrival and departure times; • Good interstate access; • No unexpected or unresolvable environmental problems; • Outstanding incentive package, and • Operationally centered for proposed hub operations. Other than what is presented above, the information used by the air cargo hub operator to evaluate the proposals submitted by interested airport sponsors was not made available to FAA for review and evaluation. This information was considered confidential by the air cargo operator, therefore FAA had no means to independently evaluate either the selection criteria or the results of the selection process. 2.2.2.3 Summary of Purpose for the Proposed Improvements PTAA's purpose is to support the growth and development of PTIA such that the airport can support a major air cargo hub, is capable of accommodating the air transportation needs of the Triad, and it remains a major employment center and economic generator in the Triad. FAA's purpose is to support locally- sponsored projects that fulfill national public policy objectives, if such projects satisfy all FAA decision criteria and if the FAA determines that projects or their reasonable alternatives are environmentally sound. 2.2.3 NEED: MEET OPERATIONAL REQUIREMENTS OF AN OVERNIGHT, EXPRESS AIR CARGO HUB Establishment of an overnight, express air cargo hub at PTIA requires that certain airside, landside and surface transportation improvements be implemented. The improvements are initially needed to meet the near- and long-term operational requirements of the overnight, express air cargo hub, within the near- term timeframe established by the carrier for PTIA. The improvements proposed by the PTAA are needed to facilitate development and efficient operation of an overnight, express air cargo hub consistent with Fed Ex business requirements. PTAA therefore seeks to support 48 daily operations (24 daily departures) by the year 2005 and 126 daily operations (63 daily departures) by the year 2009. Associated landside development is also needed that can support package processing activities at the rate of approximately 86,000 per night by the year 2005 and approximately 104,000 per night by the year 2009. All package processing must occur between the hours of 10:00 p.m. and 4:00 a.m. the following morning. The specific improvements that are needed are described more fully in the following sections and include: • An airfield system capable of providing a redundant Transport-Category runway system having a minimum length of 9,000 feet; \\clnt0l\wp_wpro\PIEDMONl1DEIS\Ch_2\Ch_2.doc\03/23/00 2-5 Chapter 2.0 Purpose and Need • An airfield system capable of allowing for the ability to conduct dual simultaneous independent operations to meet operational requirements in Instrument Flight Rules (IFR) or Instrument Meteorological Conditions (IMC), from 10:00 p.m. to 4:00 am, Monday through Friday, and • An air cargo hub development site of sufficient size, geometry and location to allow establishment and operation of the hub facility in a flexible and efficient manner. The above referenced operational levels were established by FedEx. PTAA states that for the desired full air cargo hub operational levels to be reached in 2005, Phase 1 of the hub facility must be constructed and operational by mid-year 2004. This would allow for a several month time period to test the sorting equipment and train employees. The proposed parallel runway is projected to be constructed and operational at the time that full aircraft and sorting operations would begin in early 2005. 2.2.3.1 Provide Redundant 9,000-Foot Transport-Category Runway System PTIA currently has two runways. Runway 5/23 is 150 feet wide and 10,001 feet long, is used mostly by air carrier aircraft and is considered to be the airport's primary runway. Runway 14/32 is 150 feet wide and 6,380 feet long, and is used primarily by regional air carrier and general aviation aircraft, including small business jets. The majority of current air carrier operations at PTIA are to destinations that are between 500 and 1,000 nautical miles (nm) from PTIA. The majority of air cargo operations from the proposed air cargo hub are also expected to occur to destinations between 500 and 1,000 nm. However, one daily DC-10 operation is planned for non-stop trips between PTIA and San Juan, Puerto Rico, a distance of approximately 1,760 nautical miles. One weeknight departure from PTIA to San Juan equates to 260 annual DC-10 departures or 520 annual operations. FAA's guidelines for runway length requirements (FAA AC 5090.313, Paragraph 306) are based on the designated critical aircraft and load factors operating at or forecast to operate at an airport facility. The number of aircraft operations designated by FAA for runway length requirements is 250 annual departures and/or 500 total annual operations by the critical aircraft. With the introduction of the overnight express air cargo hub at PTIA, the critical aircraft for any future runway design would be the DC-10, or similar type aircraft. In mid-1999, a detailed runway length analysis was prepared by PTAA as part of the ongoing PTIA Master Plan Update (MPU). This analysis is available at the FAA Airports District Office in Atlanta, Georgia and at the PTAA Administrative Office in Greensboro, North Carolina. The analysis was based on aircraft types currently operating at and proposed to operate at PTIA. The analysis indicated that the most critical aircraft forecast to operate at PTIA, based on weight, performance characteristics, and frequency of operations was the DC-10. The MPU analysis calculated that a fully loaded DC-10 aircraft departing PTIA for San Juan required a runway length of 10,120 feet. However, it was also determined that DC-10 aircraft could operate to the same destination, with a slightly reduced payload, with a runway length of 9,000 feet. Subsequent coordination with the air cargo operator indicated that based on their anticipated load factor, a runway length of 9,000 feet would accommodate the runway length requirements of their DC-10 on the PTIA to San Juan delivery route. It was therefore concluded that based on FAA runway length requirement guidelines, the justifiable runway length for any new or extended runway at PTIA should be WAPIEDMONMEIS\Ch_2\Ch_2.doc\03/23/00 2-6 Chapter2.0 Purpose and Need 9,000 feet in order to accommodate the runway length requirements of the forecast PTIA critical aircraft. At such time that PTAA justifies the need for a longer runway based on FAA guidelines, the extension of existing Runway 14/32 or the proposed parallel runway would undergo separate environmental review by the FAA. A second 9,000-foot Transport-Category runway at PTIA would provide a back-up runway for all aircraft during times of scheduled runway maintenance operations (overlays, repairs, aircraft rescue and fire fighting exercises, snow removal, etc.) and unforeseen emergencies (incidents), without hindering or closing down overall airport operations. Tables 2.2-1 and 2.2-2 present data collected from PTIA which details the number of times and total duration of runway closings at PTIA over the last 10 years as a result of either maintenance or incidents. As indicated, a total of 790 maintenance closures for a duration of 1,305 hours, and 293 incidents for a duration of 129 hours occurred at PTIA. Based on this past history, the FAA believes it is reasonable that approximately the same frequency of maintenance/incident runway closures could occur during the study period covered in this DEIS. Both of these statistics are significant in terms of the introduction of the proposed overnight, express air cargo hub at PTIA. At most airports, maintenance activities are routinely scheduled to occur in "off-hours", or times when it would have the least disruptive impact on aircraft operations. Although this can occur during the daytime, it is more likely to occur at night. With the introduction of air cargo hub operations to PTIA, normal maintenance activities would have to be scheduled during off-peak weekday hours or during weekends so as not to interfere with the cargo hub's nighttime operations. Having a second 9,000- foot Transport-Category runway would optimize the achievement of routine or emergency maintenance for safety considerations. Although runway incidents are not predictable, most of their impact on airport operations at PTIA would be minimized by providing a redundant 9,000-foot Transport-Category runway, which would help ensure that at least one runway was always open and operational during daytime air carrier and air cargo operations as well as during nighttime air cargo operations. Because of the nature of the air transportation industry, it is critical to the air carrier that aircraft be able to arrive and depart an airport facility without unnecessary interruption of service. To accommodate this requirement for an overnight, express air cargo hub, PTIA has proposed two Transport-Category runways of at least 9,000 feet in length, either of which would be fully capable of accommodating the required runway length and instrumentation requirements (CAT II / CAT III) for the existing and future air carrier/air cargo aircraft fleet at PTIA. This capability would be particularly important during periods of adverse weather conditions (IMC conditions which occur approximately 15 percent of the year) and to provide redundant back-up capabilities when one of the runways is closed due to maintenance and /or incidents. 2.2.3.2 Provide the Ability to Conduct Dual Simultaneous Independent Operations to Meet Operational Requirements in Instrument Flight Rules (IFR) or Instrument Meteorological Conditions (IMC) To identify the particular airfield configuration the PTAA needed to meet its air cargo hub operational objective, additional analysis was necessary. Specifically, two technical analyses, Annual Service Volume (ASV) and Total Airport and Airspace Modeling (TAAM), were undertaken to evaluate the \\clnt0l\wp_wpro\PIEDMONT\DEIS\Ch_2\Ch_2.doc\03/23/00 2-7 Chapter 2.0 Purpose and Need existing, short-term and long-term capacity of the PTIA airfield system with and without the introduction of an air cargo hub. These analyses consisted of a traditional long-range estimate of ASV and a detailed analysis of peak-period air cargo operational activity using computer-based simulation of aircraft arrival, taxi-in, taxi-out and departure movements using the TAAM. The ASV and TAAM analyses were prepared for the PTAA in mid-1999 as part of the ongoing PTIA MPU, and are available at the FAA ADO office in Atlanta, Georgia and at the PTAA Administrative Office in Greensboro, North Carolina. The following is a summary of these analyses and their findings. Annual Service Volume (ASV) Calculation -The measure of long-term airfield capacity or the capability of an airport to accommodate aircraft operations in a safe and timely manner without incurring excessive delays is typically expressed numerically as ASV, as prescribed by FAA Advisory Circular 15015060-5, Airport Capacity and Delay. ASV is the FAA's standard method of estimating an airport's "theoretical" annual operational capacity for the 20-year planning horizon, and takes into account such considerations as runway configuration, runway use, aircraft operating fleet mix, prevailing local weather conditions, taxiway configuration, arrival/departure percentage split, touch-and-go operations, and air traffic control (ATC) procedures. The most recent ASV calculation for PTIA was conducted as part of the ongoing MPU, and independently verified by the FAA as part of this DEIS. Several assumptions were used in the calculation of the ASV for PTIA. First, the analysis considered that Runway 5/23 operates as the primary runway and Runway 14/32 operates as the secondary, or cross-wind runway. Because these runways are perpendicular and physically connected, they are considered to be intersecting runways for ATC purposes. Based on a review of wind persistency data and coordination with the ATC, it was determined that aircraft takeoff and landing operations occur to the southwest approximately 54 percent of the time, and to the northeast approximately 46 percent of the time. It was also determined that Instrument Meteorological Conditions (IMC) occur approximately 15 percent of the time at PTIA. (LPA, 1998) The results of the ASV capacity analysis are typically presented in terms of Annual Service Volume. In calculating the ASV, the Hourly IFR and Visual Flight Rules (VFR) capacities were weighted according to criteria specified in FAA Advisory Circular 15015060-5, Airport Capacity and Delay. Based on these criteria, a weighted hourly capacity of 51 operations was utilized in the calculation of ASV for 1998 through 2019. The results of the ASV calculation, based on the existing two runway perpendicular configuration at PTIA are shown in Table 2.2-3, with and without the introduction of proposed air cargo hub aircraft operations. FAA planning guidelines for airports specify that when annual airport operations reach 60 percent of ASV capacity, the sponsor should initiate planning studies to evaluate means of increasing capacity (FAA AC 5090.313, Table 3-2). When operational levels approach 80 percent ASV capacity, construction of the recommended capacity based improvements should be initiated. These guidelines have been developed and are used by the FAA and airport sponsors to ensure that capacity based improvements are initiated and completed in a timely manner, before significant operational delay levels develop that would affect local airspace and the national airspace system. PTAA states that it has proposed a parallel runway \\clnt01\wp_wpro\PIEDMONT\DEIS\Ch_2\Ch_2.doc\03/23/00 2-8 Chapter 2.0 Purpose and Need TABLE 2.2-1 RUNWAY CLOSURES DUE TO MAINTENANCE Piedmont Triad International Airport Environmental Impact Statement Number of Duration of Closure Date Maintenance Closures (hours) 1988 62 86 1989 69 87 1990 62 95 1991 63 99 1992 63 99 1993 63 99 1994 72 125 1995 73 131 1996 93 136 1997 82 119 1998 85 212 1999" 3 17 Total 790 1,305 Source: Piedmont Triad Airport Authority, 1999. *Includes only first 2 months of 1999 data.

Based on FAA planning guidelines contained in FAA Advisory Circular 150/5060-5, Change 2, Airport Capacity and Delay (FAA, 1995), the greatest degree of operational capacity improvement is achieved through the development and use of widely spaced parallel runways that allow for the ability to conduct dual simultaneous independent operations. No other runway configuration provides for a comparable level of hourly and total daily operations. PTAA states that as shown in Table 2.2-3, the 60 and 80 percent FAA planning guidelines would be reached by 2001 and require construction of a new runway to start by approximately 2015, even without the introduction of the air cargo hub at PTIA. This EIS does not analyze this possibility, nor does it investigate the potential environmental impact connected to a new runway without the air cargo hub, because that contingency is not part of PTAA's current proposal. Total Airport and Airspace Modeling (TAAM) - As described above, the ASV analysis serves as the FAA's standard methodology of calculating airfield capacity for a 20-year planning horizon. However, with the proposed near-term development of the air cargo hub at PTIA, unique operational scenarios would exist. These scenarios include critical departure time requirements (push-back-to-wheels-up between 5 and 15 minutes depending on aircraft type) and the air cargo carrier's planned unique use of head-to-head operations (landings from, and departures to, the same direction), which are explained in the following paragraphs. TAAM analysis was therefore deemed a more accurate guide to planning for a proposed air cargo hub. The parameters and requirements used in the TAAM analysis (Critical Departure Time and Head-to-Head operations) were supplied to the FAA by FedEx. Critical Departure Time Requirements - To achieve the goal of handling and delivering all overnight express parcels by mid morning, FedEx considers the scheduling and movements of all flights as critical. The air transport of parcels destined for any one of the receiving stations requires that all parcels for that one location be unloaded, sorted, and reloaded aboard the aircraft prior to leaving the hub. This time- critical operation, by necessity, requires aircraft to depart the hub within clearly defined departure schedules that have very little variance or tolerance for delay. To that end, FedEx uses its own hub facility design, operational scheduling, and multi-model infrastructures to meet their operational and delivery goals. As stated by FedEx, since its inception in 1973, the company has developed a specific system of "launching" aircraft at specific departure times to meet arrival times at each of its numerous city destinations. Because the air cargo operator must meet each and every package delivery schedule at each destination city, the departure phase of the daily operations is critical. Any delays that are experienced at the hub are also experienced at each destination city and at the time of final delivery of the parcel. To meet its schedules, FedEx has established minimum departure times for its fleet of aircraft. The minimum departure time serves as an operational goal of expediting the launch of each aircraft within a W:\PIEDMON1'\DEIS\Ch_2\Ch 2.doc\03/23/00 2-9 Chapter 2.0 Purpose and Need specified period of time, which is estimated by FedEx to be approximately 70 minutes for the proposed hub at PTIA. This means that all aircraft would have to depart the proposed PTIA air cargo hub within a 70 minute timeframe in order to meet the air cargo operator's on-time delivery commitments. In the proposed 2005 opening year, 24 departures would have to occur within this 70 minute timeframe, and in the year 2009, 63 aircraft would have to be able to depart within this 70 minute timeframe. In order to be able to meet the 70 minute departure window and because the cargo aircraft fleet mix varies by aircraft size, weight, and number of engines, FedEx states that the critical departure time requirements, also known as "push back-to-wheels up" departure goals within the 70 minute departure window have been established on an aircraft-specific basis. The push back-to-wheels up time is the time between when an aircraft is pushed back from its parking position to the time the wheels are retracted into the aircraft wheel-well after departure. The carrier specific departure goals minimize the overall time it takes to accomplish this phase of departure. For the proposed overnight, express air cargo hub at PTIA, the push back-to-wheels up times have been established by FedEx as 15 minutes for large jet aircraft (DC-10, A310, A300), 7 minutes for mid-sized jet aircraft (13737, B727), 6 minutes for small jet aircraft (F27, ALM) and 5 minutes for small prop aircraft (C208). The TAAM analysis indicates that by situating the sorting and distribution hub facility between two parallel runways, the overall time to launch time-critical movements of air cargo aircraft would be reduced. The TAAM analysis also indicates that without the combined use of widely spaced parallel runways, a centrally-located hub facility, and the use of minimum departure times, the overnight, express air cargo hub aircraft could not effectively and efficiently operate at PTIA. FAA recognizes that while the application of minimum departure push back-to-wheels up times established by this air cargo operator for its hub operations are unique, industry standard shows that other overnight express parcel carriers also depend on similar time minimization techniques at their respective hub/sort facilities to meet their operational goals. Head-to-Head Operations - Head-to-head operations involve the use of a runway system in pre-defined operational flows (e.g., arrivals from one direction, subsequent departures to the same direction). This operational use of runways is highly restrictive and is rarely used at most airports because it would not typically support efficient flow control procedures into and out of the PTIA Terminal Airspace and Regional FAA Centers when employed by multiple users. Furthermore, the interaction of multiple Terminal Airspace users using traditional and head-to-head flows would pose considerable air traffic controller work loads while also degrading overall capacity and safety to all users. To achieve the greatest airfield capacity benefit from this type of operational procedure, several criteria must be meet. First, this type of procedure should occur on widely spaced parallel runways that allow for the ability to conduct dual simultaneous independent IFR operations. Second, the procedure should be used outside of the scheduled times of all other air carrier operations (i.e. there should be sole occupation of the Terminal Airspace by a single user, and its use should occur during times of lowest potential for interference with other Terminal Airspace operations). Finally, there needs to be established a Memorandum of Agreement (MOA) between the airport, Air Traffic Control Tower, and the user that clearly defines the operational rules that would apply during times that head-to-head operations are employed. \\clnt01\wp_wpro\PIEDMONTDEIS\Ch_2\Ch_2.doc\03/23/00 2-10 Chapter 2.0 Purpose and Need Review of the proposed project indicates that head-to-head operations at PTIA could be utilized by the overnight, express air cargo operator because the proposed project would develop a widely spaced parallel runway, because the majority of aircraft operations from the proposed air cargo hub would occur during late night and early morning hours when no other air carrier service is scheduled (between 10:00 p.m. and 4:00 a.m. the following morning), and because preliminary discussions between the airport, Air Traffic Control (ATC) and the air cargo operator indicates that an MOA could be established and implemented by all concerned parties. Air Traffic Control procedures as well as weather and wind permitting, head-to-head operations are possible at PTIA with parallel runways. With parallel arrival and departure streams on Runways 51J23R and 5R/23L, PTAA, ATC and the air cargo operator estimate that arrivals from the southwest and departures to the southwest could occur approximately 95 percent of the time. PTAA states that this arrival and departure system would provide the most efficient ingress and egress of the PTIA by the air cargo hub aircraft during peak air cargo operational periods, would sere to expedite the handling of air cargo hub aircraft movements within the airport's terminal airspace and would sere to provide the airfield capacity required by the air cargo operator to meet their peak hour operational requirements. It is important to note that the airfield capacity benefits of using head-to-head operations can only be achieved through the use of parallel runway configurations. Head-to-head operations using non-parallel runway configurations (e.g., use of perpendicular runways) would yield reduced airfield capacities that are severely limited by safety and wake turbulence considerations (Order 7110.98A, Simultaneous Converging Instrument Approach, FAA, 1993 and Order N7110.157, Wake Turbulence, FAA, 1996). TAAM Analysis - Because of the above described unique operational considerations, the standard ASV calculation discussed previously in this section did not provide enough information, according to PTAA, to allow them to develop an airfield configuration proposal that addressed the issues raised by introduction of an air cargo hub. The PTAA and the FAA determined that ASV did not sere as an appropriate measure of required airfield capacity, or as a realistic measure of peak operational delay. An alternative method of assessing airfield capacity was required. It was decided to use the TAAM, which is a commercially available, non-propriety, simulation software package to analyze the existing (perpendicular) and proposed (parallel) runway configurations at PTIA. The TAAM analysis was used to identify any potential operational capacity shortfalls for a cargo hub operation associated with the existing runway configuration, and whether these potential shortfalls would be relieved under a parallel runway orientation. Using computer-based simulations of aircraft arrivals, taxi-in, taxi-out, and departure movements, the TAAM provided a measure of numerous components of aircraft operations associated with the proposed air cargo hub, including delineation of air cargo hub operations from non-cargo hub operations; assessment of air cargo hub-formulated "push-back-to- wheels-up" minimum departure time criteria; arrival/departure delay time and average block hour cost for the air cargo hub operator, and total delay time and average block hour cost for the air cargo hub operator. W:\PIEDMONl1DEIS\Ch_2\Ch_2.doc\03/23/00 2-11 Chapter 2.0 Purpose and Need The results of the TAAM analysis using the parameters provided by FedEx indicated that the air cargo carrier would not be able to meet its operational requirements using the existing perpendicular runway configuration at PTIA for several reasons. First, the location of the proposed air cargo hub sorting and distribution facility (see Section 2.2.3.3 below) and the relative distance to the farthest runway ends (Runway 14 and Runway 32) made for taxi-times in excess of the air cargo carrier's maximum taxi-time per aircraft type. In addition, the perpendicular runway configuration was not conducive to the use of head-to head operations. Finally, the perpendicular runway configuration did not allow for the ability to conduct dual simultaneous independent all-weather arrivals and dual simultaneous independent departures during peak departure periods. The results of the TAAM analysis for the parallel runway configuration indicated that for several reasons, the air cargo carrier would be able to meet more of its minimum push-back-to-wheels-up departure times than with the existing perpendicular runway orientation. This was because the proximity of the proposed hub facility to the runway ends (Runway 23L and 23R) greatly improved taxi-time efficiency, the parallel runway system allowed for head-to-head operations, and the availability of widely-spaced parallel runways allowed for the ability to conduct dual, simultaneous independent all-weather arrivals and dual simultaneous departures of aircraft during peak departure periods. A more detailed description of the TAAM analysis is contained in Chapter 3.0, Alternatives. The overall results of the TAAM analysis indicated that without the use of a mid-field hub and the availability of a widely-space parallel runway system that allowed for the ability to conduct dual simultaneous independent IFR operations, the air cargo operator would not meet most of its time-critical minimum operational requirements at PTIA. 2.2.3.3 Provide a Development Site Meeting the Operational Needs of an Air Cargo Sorting and Distribution Facility (FedEx Mid-Atlantic Hub) In addition to meeting the airside needs of the air cargo carrier discussed above, an air cargo hub facility site itself must be able to accommodate the air cargo carrier's operational needs. The PTAA has determined that meeting this operational site need requires the careful integration of airside, landside, and sorting facilities that, by the unique nature of hub requirements, has limited flexibility in the variation of layout, orientation, and proximity to airside and surface transportation facilities. In order to meet its operational requirements, FedEx proposed to PTAA at a minimum, an on-airport development site having the following characteristics: • Approximately 300 contiguous acres; • Rectangular shape to accommodate airside, landside, sort facility and surface transportation integration requirements; • Close to existing and future planned airside, landside and surface transportation systems; • Located between parallel runways to provide optimal operational efficiency for aircraft arrival and departure operations; and \\clnt01\wp_wpro\PIEDMONl1DEIS\Ch_2\Ch_2.doc\03/23/00 2-12 Chapter2.0 Purpose and Need • Constructable such that the first phase of the facility would be operational by the year 2004. As described by FedEx, on-airport operations involve a complex interaction of multi-modal transportation systems. The development of an air cargo hub facility at PTIA would require ample on-airport land areas that can be co-located with existing and future air and surface transportation infrastructure. According to FedEx, simultaneous operations by numerous cargo aircraft, ground support, loading, and surface vehicles must occur in a highly orchestrated manner within pre-defined time periods that are predicated on national and international next-day delivery schedules at the various distribution centers. Because of this logistical dependency, the first outbound departure to a destination city cannot occur until the last parcels aboard the last inbound aircraft have been unloaded, sorted, and reloaded aboard other outbound aircraft destined for various distribution stations. The PTAA states that there is a critical need therefore, for the location, size and orientation of the hub sorting and distribution site to meet the air cargo carrier's operational requirements. Based on its business plan for the development of the proposed air cargo hub at PTIA, FedEx has determined that the first phase of the sorting and distribution facility must be constructed and fully operational by early 2005. In order to accomplish this, the sorting and distribution facility must be fully constructed by mid-2004 to allow for a six month personnel training and equipment "break-in" period. The sponsor states that it must meet this schedule to accomplish its objective of siting an air cargo hub at PTIA. 2.2.3.4 Purpose and Need Summary The purpose and need for the proposed project is to develop facilities at PTIA that would provide airside, landside and surface transportation improvements to support the development and efficient operation of an overnight, express air cargo hub facility (FedEx Mid-Atlantic Hub) at PTIA. Through detailed TAAM simulation analysis, PTAA determined that these needs could best be met by the development of a widely-spaced Transport-Category parallel runway, with the air cargo hub facility located between the parallel runways. The demand for the air cargo hub at PTIA is driven by the air cargo hub operator which wishes to place an express, overnight air cargo movement hub within the southeastern United States. The development of the air cargo hub at PTIA is in keeping with the PTAA's interest in ongoing airport development and expansion to meet the air service and economic development needs of the Triad. The purpose of the proposed project is consistent with FAA's objective to support locally-sponsored projects that fulfill national transportation public policy objectives if these projects are otherwise acceptable and consistent with other FAA mandates, including those established by NEPA. \\c1nt01\wp_wpro\PIEDMONT\DEIS\Ch_2\Ch_2.doc\03/23/00 2-13 Chapter 2.0 Purpose and Need 2.3 REQUESTED FEDERAL ACTIONS The Federal actions being considered for approval are: The approval of revisions to the PTIA ALP for proposed development which includes a widely spaced 9,000-foot Transport Category parallel runway, air cargo hub facility and associated developments; and The Federal environmental approval necessary to proceed with processing of an application for Federal funding for those development proposals qualifying under the former Airport and Airway Improvement Act of 1982, as amended, and recodified at 49 USC 47101 et seq., or approval to use Passenger Facility Charges (PFC's). Although future projects other than the proposed parallel runway and the cargo hub facility are depicted on the ALP, the PTAA is requesting FAA environmental approval only for the proposed parallel runway, the cargo hub facility, and associated projects assessed in this DEIS as part of Phase 1 (1999-2005) and Phase 2 (2006-2009). If the PTAA proposes to the FAA to construct other projects that currently appear on the ALP, the FAA will review use proposals under NEPA at the time they are requested.

The Council on Environmental Quality (CEQ) regulations implementing the National Environmental Policy Act (NEPA) stipulate that alternatives are the heart of the environmental impact statement. Those regulations require that the Federal decision-maker perform the following tasks: • "Rigorously explore and objectively evaluate all reasonable alternatives and, for alternatives which were eliminated from detailed study, briefly discuss the reasons for their having been eliminated." • "Devote substantial treatment to each alternative considered in detail, including the proposed action, so that reviewers may evaluate their comparative merits." • "Include reasonable alternatives not within the jurisdiction of the lead agency." • "Include the alternative of no action." The range of alternatives examined in this DEIS has been generated to satisfy the purpose and need described in Chapter 2. PTAA submitted a proposal to the FAA for airside and landside developments that would meet the operational requirements for a Mid-Atlantic Cargo Hub submitted to it by FedEx. It is important to note that if airport improvements are to be built, the PTAA has the role of planning, constructing, and operating the runways at the airport. The FAA has generated alternatives, on its own and through the Scoping process (which yielded additional options submitted by an interested citizen group and the sponsor itself) that go somewhat beyond the limited consideration that might be afforded a proposal such as this. That is, in some circumstances such as these, where the sponsor's proposal is tied to sought-after business development with a particular commercial operator, it appears that the only alternative to the sponsor's proposed project is "No-Action". In this particular case, however, by concentrating on the near-term operational requirements of an overnight express air cargo hub, the FAA found that a larger range of alternatives should be identified and evaluated. As a result, off-site as well as a significant number of on-site alternatives were developed and explored which might meet the purpose and need for this project (provide redundant 9,000-foot Transport Category runways, provide for the ability to conduct dual simultaneous independent IFR operations, and provide a sort/distribution facility site of sufficient size, location and configuration to meet hub operational requirements. W:\PIEDMONT\DEIS\Ch_3\Ch_3.doc\3/24/00 3-1 Section 3.0 Alternatives As described in Chapter 2.2, the role of the FAA in this case is to disclose and evaluate potential environmental impacts that may result from the sponsor's proposed project being considered, including impacts on the safe and efficient use of airspace. 3.2 ALTERNATIVES EVALUATION PROCESS The FAA completed a thorough and objective review of reasonable alternatives to PTAA's proposed project at PTIA. CEQ regulations require that an agency look at "reasonable" alternatives, while 49 U.S.C. 47106(c)(C) requires as a condition to granting Federal funds, an analysis of "possible and prudent" alternatives for a new runway when significant impacts would occur." With those standards in mind, the FAA did not evaluate alternatives in detail if they showed no possibility of meeting the project purpose, as described previously, or no prospect of being built. One category of alternatives that was considered early in the DEIS process but was not retained for further consideration was the use of other modes of transportation. Other modes of transportation include the use of roadway, conventional rail, and high-speed rail as an alternative to the proposed project. FAA determined that alternative modes of transportation do not provide a reasonable fit with the project objectives. From the sponsor's perspective, alternative modes of transportation do not meet the purpose of the project. As presented to the FAA, the proposed air cargo hub requires the fast, efficient movement of goods over a broad geographic region. While another mode might provide desirable surface transportation services, the only mode of transportation that can best meet the combined need for range and speed is air transportation. Therefore, other modes were eliminated because they could not provide the facilities required for overnight air cargo/package operations. As indicated in Chapter 2.0, Purpose and Need, of this DEIS, the FAA has carefully examined the purposes and needs for PTAA's proposed project at PTIA in consideration of the range of reasonable alternatives identified by the FAA. This analysis identifies which alternatives might reasonably meet the purpose and need statements described in Chapter 2.0, Purpose and Need, of this DEIS. Those alternatives that did not reasonably meet the project purpose and need, or were determined not feasible, were not considered further within this DEIS. However, the No-Action Alternative was carried through detailed environmental analysis for baseline comparative purposes to fulfill CEQ requirements, to disclose potential impacts if the project is not built, and to disclose potential environmental impacts associated with the cumulative actions. In the development of this DEIS, the FAA re-examined the recommendations of previous and ongoing PTIA Master Plan studies and independently evaluated numerous alternatives for further consideration. • Off-site alternatives that were examined included: • Development of a new airport, • Use of other existing airports within the Air Cargo Service Region. • On-site alternatives that were examined included: \\cln101\wp_wpro\PIEDMONTDEIS\Ch_3\Ch_3.doc\3/23/00 3-2 Section 3.0 Alternatives • No-Action, • PTAA's Proposed Project, • An alternative plan submitted by interested citizens during Public Scoping, and • Various widely spaced parallel runway configurations and sort/distribution facility locations. The alternatives evaluation utilized a two-level evaluation process formulated to concentrate on the purpose and need for the proposed project and the reasonableness of the alternatives. Those alternatives that did not meet the purpose and need would be eliminated from further consideration. As the alternatives evaluation proceeded through each level of analysis, certain alternatives that did not meet the criteria were eliminated from further evaluation. Those that met the criteria continued on to the next level of analysis. At the conclusion of the second level of evaluation, those alternatives that remained were subject to detailed analysis in subsequent chapters of this DEIS. The following briefly describes the evaluation criteria used in the analysis of alternatives. 3.2.1 LEVEL 1 ANALYSIS: PURPOSE AND NEED CRITERIA The first level of analysis evaluated whether the various alternatives met the purpose and need criteria specific to the airfield (development of the air cargo hub at PTIA, provide redundant 9,000 foot Transport Category runways, provide for the ability to conduct dual simultaneous independent IFR operations, provide a sort/distribution facility site of sufficient size, location and configuration to meet the proposed air cargo hub's operational requirements) established in Chapter 2.0, Purpose and Need, of this DEIS. Those alternatives that satisfied the first-level criteria were retained for evaluation under the second level of analysis. The following presents a summary of the Level 1 criteria used in the alternatives screening process. 3.2.1.1 Develop an Air Cargo Sorting and Distribution Hub Facility (FedEx Mid-Atlantic Hub) at PTIA After a detailed evaluation of potential locations, the PTIA was selected by FedEx in April 1998 as the preferred site for the establishment of their Mid-Atlantic Hub to serve FedEx's eastern United States market. The initial selection of the placement of the air cargo hub in either North Carolina or South Carolina was based on a business decision made by FedEx. As FedEx has stated, the location of the hub within these two states was based on several considerations unique to its business, including requirements that the hub be located on the East Coast of the United States, the hub be sited so that its market service area was located within a single time-zone, the hub be centrally located within the projected East Coast market area, and the hub be located in an area of moderate weather patterns to reduce the likelihood of interruption of service due to inclement weather conditions. FedEx states that it selected PTIA for the site of its Mid-Atlantic Hub because PTIA was the top-rated airport in all criteria including detailed analysis of Airport Operations, Site Selection, and Financial Analysis (see Section 2.2.2). According to FedEx, none of the other airports considered were competitive with PTIA in all of these criteria. \\c1nt01\wp_wpro\PIEDMONTDEIS\Ch_3\Ch_3.doc\3123/00 3-3 Section 3.0 Alternatives The ultimate decision to locate the air cargo hub at PTIA is a decision that rested with FedEx and the PTAA. The sponsor's purpose for the proposed project is the development of improvements to support the air cargo hub facility at PTIA. The Level 1 criteria could not be developed without reference to the specific airfield requirements that are part of the proposed project. However, the Level 1 criteria were also applied to off-site locations, because the FAA recognized that PTIA is not the only location that could support an air cargo hub, and because the FAA sought to address questions about siting raised by local communities in the proposed project area. 3.2.1.2 Provide Redundant 9,000-Foot Transport-Category Runway System The air transportation industry relies on aircraft ability to arrive and depart an airport facility without unnecessary service interruptions. As detailed in Chapter 2.0, Purpose and Need, disruptions to aircraft operations, either on the ground or in the air, could lead to significant operational and economic consequences. At PTIA, a second 9,000-foot runway would increase the safety of all operations at PTIA by providing a back-up runway capable of accommodating the runway length requirements of all aircraft currently operating at and forecast to operate at PTIA during periods of adverse weather conditions and during times of unforeseen runway emergencies (incidents) and scheduled and unscheduled runway maintenance operations (overlays, repairs, Aircraft Rescue and Fire Fighting exercises, snow removal, etc.) without adversely affecting overall airport operations, degrading service to air travelers at PTIA, or disrupting peak air carrier and air cargo operational periods. In the Level 1 analysis, therefore, only those alternatives that would provide redundant 9,000-foot Transport-Category runways were considered for further analysis. 3.2.1.3 Provide the Ability to Conduct Dual Simultaneous Independent Operations in /FR Conditions As discussed in Chapter 2.0, Purpose and Need, to achieve the short-term operational requirements of the proposed air cargo hub facility at PTIA, capacity related airfield improvements to the existing perpendicular two-runway system at PTIA are needed. Based on FAA planning guidelines, the greatest degree of operational capacity improvement is achieved through the development and use of widely spaced parallel runways that allow for the ability to conduct dual simultaneous independent operations in all weather conditions. No other runway configuration provides for a comparable level of hourly and total daily operations. (FAA AC 150/5060-5, Change 2, Airport Capacity and Delay, 1995). The capacity related benefits to both air carrier and air cargo aircraft operations at PTIA both with and without the ability to conduct dual simultaneous independent operations in all weather conditions was evaluated by the PTAA as part of the ongoing Master Plan Update project using a TAAM analysis. To assess the operational efficiency of the existing perpendicular and proposed parallel runway systems, a comparison of the proposed schedules of the air cargo hub daily operations at PTIA for the years 2004, 2006, 2009, and 2019 were modeled using the TAAM. For each study year, the TAAM was used to assess operational movements, times, and associated cost impacts to the push-back-to-wheels-up times for the existing airfield configuration and the proposed parallel runway system scenarios. W:\PIEDMONIIDEIS\Ch 3\Ch 3.doc\3/24/00 3-4 Section 3.0 Alternatives To assess the relative affect on operational delay for air cargo hub operations at PTIA under both runway configurations, all airport arrival and departures operations throughout a typical, single 24-hour day within each study year was simulated. Specific information regarding air cargo hub operations during the critical nighttime departure period were programmed within the TAAM simulation to form key simulation rule bases. Rule bases are preformulated, logical rules of operation (i.e. if, then, else statements). These rule bases were developed using data and information obtained from air carrier flight schedules, the air cargo carrier flight schedules, and examination of all other typical aircraft movements throughout the airport (i.e., general aviation, and other dedicated cargo carriers). The TAAM rule base provided a realistic appraisal of arrival/departure routes to and from city pairs, aircraft fleet mix, time of operation, and air traffic control procedures. Special consideration was given to the planned air cargo hub operations at PTIA such as the nighttime departure "push", head-to-head operations on parallel runways, the relative degree of operational freedom provided by Air Traffic Control (ATC) during nighttime departures to destination cities (using a more direct route) and the less restricted use of airspace within the PTIA terminal area. In the analysis, the TAAM compared the average daily and annual aircraft operational delay to the air cargo carrier operations in terms of time (hours, minutes, and seconds) and cost (using average aircraft variable block hour operating costs per FAA document FAA APO-98-8). Aircraft operational delays to the air cargo carrier included delays incurred while conducting arrivals or departures that were caused by air traffic control requirements (sequencing and wake turbulence considerations), and those operational delays incurred while taxiing to and from the runway environment. Air cargo aircraft operational delays that were in excess of pre-determined maximum ground operation times for its launch period operations were also measured and assessed in terms of time and costs. The monetary comparisons of the relative change in operational delay for the air cargo carrier during the departure period was developed by utilizing the FAA-approved, aircraft-specific, average aircraft variable block hour costs. Under the existing perpendicular runway configuration, the TAAM analysis modeled air cargo operations from the proposed hub location in the northwest quadrant of the airport, use of existing Runway 5/23 as the primary runway for all large (DC-10) and medium (13737) aircraft and, to the greatest extent possible, the use of Runway 14/32 as a secondary runway for a limited number of small (ALM, F28, C208) aircraft. The results of the TAAM analysis indicated that the air cargo carrier would not be able to meet its operational requirements using the existing perpendicular runway configuration at PTIA for several reasons. First, the location of the proposed air cargo hub sorting/distribution facility and the relative distance to the farthest runway ends (Runway 14 and Runway 32) made for taxi-times in excess of the air cargo carrier's maximum taxi-time per aircraft type. In addition, the perpendicular runway configuration was not conducive to the use of head-to head operations. Finally, the perpendicular runway configuration did not allow for the ability to conduct dual simultaneous independent all-weather operations. Under the proposed parallel runway configuration, the TAAM analysis modeled the air cargo operations from the proposed hub location in the northwest quadrant of the airport, between the two widely-spaced parallel runways. Large aircraft operations were split between the parallel runways based on origin- destination city pairs. Runway 14/32 was used for a limited number of medium aircraft and all small aircraft. The results of the TAAM analysis for the parallel runway configuration indicated that for several reasons, the air cargo carrier would be able to meet more of its minimum push-back-to-wheels-up \\clnt01\wp_wpro\PIEDMONTDEIS\Ch_3\Ch_3.doc\3/23/00 3-5 Section 3.0 Alternatives departure times than with the existing perpendicular runway orientation. This was because the parallel configuration can accommodate a larger number of operations in a shorter time block than a perpendicular configuration, the proximity of the proposed hub facility to the runway ends (Runway 23L and 23R) greatly improved taxi-time efficiency, the parallel runway system allowed for head-to-head operations, and the availability of widely-spaced parallel runways allowed for the ability to conduct dual, simultaneous independent all-weather operations. Using the TAAM, a comparison of the annual air cargo operations cost for each study year for both the existing perpendicular and proposed parallel runway configurations was prepared. As shown in Table 3.2.1-1, the daily and annual air cargo carrier's operations costs would be reduced by as much as 37 percent under the proposed parallel runway scenario when compared to the existing perpendicular runway configuration. The cost savings are a direct reflection of the inherent efficiencies associated with the use of a widely-space parallel runway system, the use of head-to-head arrival/departure operations, and the relative proximity of the air cargo hub facility between the two parallel runways. The primary need for the proposed parallel runway and its associated operational benefits are evident in Tables 3.2.1-2 and 3.2.1-3. In these tables, the data illustrates that within each planning year, the total air cargo carrier departure time and costs would be significantly reduced for the parallel runway configuration when compared to the existing perpendicular runway configuration. The TAAM analysis revealed the following data regarding the resultant changes in aircraft operational delay as a direct result of developing a parallel Runway 5L/23R at PTIA: • The air cargo carrier would be able to significantly reduce the number of flights that would exceed the minimum push-back-to-wheels-up departure times primarily because the proposed hub facility and aircraft parking/loading positions would be located between the parallel runways, because head-to-head operations would be utilized, and because the parallel runway configuration would allow for the ability to conduct dual, simultaneous independent all-weather arrivals and dual simultaneous departures during peak departure periods. • The air cargo carrier would not achieve and maintain its desired on-time overnight delivery service or meet its pre-established maximum ground time operational goals at PTIA without the construction and use of a parallel runway system. • As a direct result of the inherent efficiencies of a widely-spaced parallel runway system offering dual, simultaneous independent operational capabilities, all users of PTIA would experience reductions in overall operational delay in the future. • Because of the proximity of the existing passenger terminal and all other general aviation facilities, certain non-air cargo users would experience longer ground taxi distances, taxi times, and associated block hour operating costs when operating on the proposed parallel Runway 51J23R. However, because of the resultant increase of airfield capacity derived from the use of the parallel runway, reductions of ground-based delay and associated block hour costs for taxi and in-flight arrival/departures operations are anticipated to be significantly reduced. These reductions in time and cost would be most apparent during the two daily peak air carrier operational periods (10 a.m. to 2 p.m. and 5 p.m. to 7 p.m.) especially as overall operational demand increases throughout the 20-year planning period. Therefore, through the use of parallel runways, the cost of operational delay and \\clnt01\wp_wpro\PIEDMONT\DEIS\Ch_3\Ch_3.doc\3/23/00 3-6 Section 3.0 Alternatives TABLE 3.2.1-1 COMPARISON OF FedEx OPERATIONS COST Piedmont Triad International Airport Environmental Impact Statement DAILY Year 2004 2006 2009 2019` Existing Configuration $16,994 $31,709 $49,625 $48,338 Proposed Project $11,924 $19,839 $33,045 $31,621 Reduction $5,070 $11,870 $16,580 $16,717 Percent 28.83% 37.43% 33.41 % 34.58% ANNUAL Year 2004 2006 2009 2019 Existing Configuration $5,913,912 $11,034,732 $17,269,500 $16,821,624 Proposed Project $4,149,552 $6,903,972 $11,499,660 $11,004,108 Reduction $1,764,360 $4,130,760 $5,769,840 $5,817,516 Percent 29.83% 37.43% 33.41% 34.58% Source: TAAM, JDA; Table No. 9.

W:\PIEDMONT\DEIS\\Ch_2\TBL_321.3.doc\02/23/00 associated average aircraft variable block hour operating costs would offset the additional taxi distance experienced by non-air cargo users. • Through the use of the parallel Runway 5U23R, reduced taxi times, and improved overall ground handling of aircraft by ATCT, the push-back-to-wheels-up departure times for most of the DC-10, A310, and A300 aircraft would be significantly reduced to less than 10 minutes. These reduced departure times are considered critical to meeting the on-time operational goals of overnight air cargo hub. In summary, based on the TAAM analysis, both a mid-field hub facility location and the ability to conduct dual simultaneous independent IFR operations on a widely-spaced parallel runway system are needed at PTIA to meet the air cargo operator's push-back-to-wheels-up minimum departure times established for the air cargo hub and to ensure the ability to conduct cost- and operationally-efficient hub operations. Without the use of a mid-field hub and the availability of a widely-space parallel runway system, the air cargo carrier would not be able to meet most of its time-critical minimum operational requirements at PTIA. In the Level 1 analysis therefore, only those alternatives that would provide the ability to conduct dual simultaneous independent IFR operations on parallel runways, with a hub site located between the parallel runways, were considered for further analysis by the FAA in this DEIS. 3.2.1.4 Provide a Facility Development Site Meeting the Operational Needs of an Air Cargo Sorting and Distribution Hub (FedEx Mid-Atlantic Hub) In addition to meeting the airside needs of an air cargo hub discussed above, the proposed air cargo hub facility development site itself must be able to accommodate the operational needs of the hub operator. Meeting this operational site need requires the careful integration of airside, landside, and sorting facilities that, by the unique nature of hub requirements, has limited flexibility in the variation of layout, orientation, and proximity to airside and surface transportation facilities. As proposed by PTAA and the air cargo hub operator, and used by the FAA in its analysis of potential impacts in the alternatives evaluation, the hub facility at PTIA would require at a minimum, an on-airport development site having the following characteristics: • Approximately 300 contiguous acres; • Rectangular shape to accommodate airside, landside, sort facility, and surface transportation integration requirements; • Close to existing and future planned airside, landside, and surface transportation systems; and • Located between widely spaced parallel runways to provide optimal operational efficiency for aircraft arrival and departure operations (ability to conduct dual simultaneous independent all weather operations and head-to-head operations). Therefore, in the Level 1 analysis, only those alternatives that would fulfill the air cargo hub site requirements listed above were considered for further analysis by the FAA in this DEIS. Alternatives were \\clnt0l\wp_wpro\PIEDMONTDEIS\Ch_3\Ch_3.doc\3/23/00 3-7 Section 3.0 Alternatives eliminated from further consideration if they would result in: (a) insufficient contiguous development area, or (b) site geometry precluding efficient utilization of airside and landside resources. 3.2.2 LEVEL 2 ANALYSIS: CONSTRUCTABILITY, COST CONSIDERATIONS AND ENVIRONMENTAL IMPACTS Level 2 of the alternatives analysis was designed to determine which alternatives were considered feasible, possible and prudent alternatives to the proposed project. These criteria were specific to the financial and physical environments affected by such a project. This level of the alternatives analysis considered "aonstructability" parameters including effects on infrastructure, amount of property acquisition, number of residences relocated and businesses impacted by each alternative, the cost of the alternatives and preliminary environmental impacts of the alternatives. Alternatives that were retained after the Level 2 evaluation are the subject of detailed analysis in Chapter 5.0, Environmental Consequences. The following presents a summary of the Level 2 criteria used in the alternatives screening process. 3.2.2.1 Infrastructure The effects of each of the alternatives on existing infrastructure were evaluated in the Level 2 screening process. This consisted of quantification of impacts to existing infrastructure, including roadways and rail- lines. This evaluation criterion was used because impacts to existing infrastructure can affect airside and landside operations; the complexity of staging, phasing, and construction activities; the coordination and integration of the proposed project with other ongoing development projects; the safety of the general public; the ability to obtain all the required Federal, state, and local permits; and the total cost of a project. In this context, proximity to an existing interstate system, for site access, would be a factor to consider in siting an air cargo hub facility. Therefore, in the Level 2 analysis, those alternatives that resulted in greater impacts to existing and planned infrastructure were considered to be less feasible and prudent than those that resulted in fewer infrastructure impacts. 3.2.2.2 Property Acquisition The effects of each of the alternatives in terms of the number and type of properties that would have to be acquired were evaluated in the Level 2 screening process. This consisted of quantification of the number and type (residential, commercial, manufacturing, etc.) and cost of properties that would have to be acquired to construct the proposed airside and landside facilities associated with the alternative. Similar to the infrastructure discussion above, the amount and type of property acquisition required for an alternative can have multiple effects on the implementation of a proposed project. Residential property acquisition results in social impacts and increases the cost of a project, but can generally be accomplished within a relatively short timeframe. Acquisition of commercial and manufacturing properties generally results in less social impact, but is more expensive than residential acquisition and can take extended periods of time for completion of the acquisition process. Therefore, in the Level 2 analysis, a comparison was made of the acquisitions associated with each alternative. Those alternatives that resulted in no acquisition or lower amounts of residential and commercial/manufacturing property acquisition were considered to be more feasible and prudent than those that required extensive property acquisition. \\clnt0l\wp_wpro\PIEDMONT\DEIS\Ch_3\Ch_3.doc\3/23/00 3-8 Section 3.0 Alternatives 3.2.2.3 Relocations The effects of each of the alternatives in terms of the number and type of relocations that would have to occur was evaluated in the Level 2 screening process. This consisted of quantification of the number and type (residential, commercial, manufacturing, etc.) of properties that would have to be relocated to construct the proposed airside and landside facilities associated with the alternative. Similar to the infrastructure and acquisition discussions above, the amount and type of facility relocations required for an alternative can have multiple effects (social impacts, increased cost, extended timeframes) on the implementation of a proposed project. Therefore, in the Level 2 analysis, a comparison was made of the number and type of relocations associated with each alternative. Those alternatives that resulted in no relocations or lower amounts of relocation were considered to be more feasible and prudent than those that required extensive relocations. 3.2.2.4 Comparative Cost Considerations The evaluation of comparative costs for each of the alternatives involved an analysis of the total costs of those portions of the alternatives that would be eligible for Federal funding. This did not include other costs that are not eligible for Federal funding and would be borne directly by the air cargo hub operator for the development of its sorting/distribution facility. The cost of the various alternatives considered the following items: • Costs associated with infrastructure impacts, • Costs associated with property acquisition, • Costs associated with construction induced relocations of residences and businesses, and • Costs associated with construction of a runway and associated improvements (including mitigation for impacts to the environmental categories discussed in Section 3.2.2.5). In the Level 2 analysis, alternatives with lower total project costs were considered more feasible and prudent than those with higher total costs. 3.2.2.5 Environmental Impacts Level 2 of the alternatives screening analysis also evaluated the potential for the alternatives to cause or result in environmental impacts. The initial screening process focused on several environmental categories that are protected under special purpose environmental laws and that contain specific provisions for the avoidance and minimization of impacts. These categories include wetlands, floodplains, Department of Transportation Section 303(c) sites and historic and archaeological resources. The following provides a brief overview of these categories. Detailed analysis of other environmental categories covered by specific protective or restorative Federal legislation including noise, air quality, endangered species, and hazardous materials was also conducted for those alternatives that were \\c1nt01\wp_wpro\PIEDMONTDEIS\Ch_3\Ch_3.doc\3/23/00 3"9 Section 3.0 Alternatives retained for detailed evaluation by meeting all of the purpose and need criteria. A summary of impacts for each of the 21 environmental impact categories contained in Order FAA 5050.4A is contained in Table 3.4-1. Detailed discussions of all of the environmental categories are contained in Chapter 5.0, Environmental Consequences. Wetlands - Executive Order 11990 states that Federal agencies should avoid to the extent possible the long- and short-term adverse impacts associated with the destruction or modification of wetlands and to avoid direct or indirect support of new construction in wetlands wherever there is a practicable alternative. Impacts should only be allowed if there is no practicable alternative to a proposed project, and the proposed project includes all practicable measures to minimize harm to wetlands. In keeping with the direction provided in Executive Order 11990, as well as that provided in DOT Order 5660.1 A, Section 10 of the Rivers and Harbors Act of 1899 and the Clean Water Act, the FAA evaluated each of the remaining alternatives in the Level 2 screening process based on the approximate acreage, type, and value of wetlands that would be impacted. Those alternatives that would result in no impacts or minimal impacts to wetlands were considered to be more prudent than those alternatives that would result in a greater amount of impacts. Floodplains - Executive Order 11988 directs Federal agencies to "take action to reduce the risk of flood loss, to minimize the impact of floods on human safety, health and welfare, and to restore and presence the natural and beneficial values served by floodplains...". The Executive Order and DOT Order 5650.2 establish a policy for Federal agencies to avoid taking an action within a 100-year floodplain where practicable. Every effort must be made to minimize the potential risks to human safety and property damage and the adverse impacts on natural and beneficial floodplain values. In keeping with the policy provided in Executive Order 11988 and DOT Order 5650.2, the FAA evaluated each of the remaining alternatives in the Level 2 screening process based on the approximate acreage of 100-year floodplains that would be impacted. Those alternatives that would result in no impacts or minimal impacts to floodplains were considered to be more prudent than those alternatives that would result in a greater amount of impacts. Section 303(c) Properties (formerly DOT Section 4(f)) - Section 303(c) of the Department of Transportation (DOT) Act of 1966 provides that "the Secretary shall not approve any program or project which requires the use of any publicly owned land from a public park, recreation area, or wildlife and waterfowl refuge of national, state, or local significance or land of an historic site of national, state or local significance as determined by the official having jurisdiction thereof unless there is no feasible and prudent alternative to the use of such land and such program or project includes all possible planning to minimize harm resulting from the use." In keeping with the direction provided in Section 303(c), the FAA evaluated each of the remaining alternatives in the Level 2 screening process based on the potential to result in direct or indirect impacts to properties protected under Section 303(c). Those alternatives that would result in no impacts or minimal impacts to Section 303(c) sites were considered to be more prudent than those alternatives that would result in a greater amount of impacts. Historic and Archaeological Resources - Historic and archaeological resources are protected under several Federal laws. The most applicable to the proposed project are the National Historic Preservation W:\PIEDMONT\DEIS\Ch_3\Ch_3.doc\3/24/00 3-10 Section 3.0 Alternatives Act of 1966 and the Archaeological and Historic Preservation Act of 1974. Both of these laws provide guidance to Federal agencies concerning Federal actions affecting historic and archaeological resources included in or eligible for inclusion in the National Register of Historic Places. In keeping with the direction provided in these laws, the FAA evaluated each of the remaining alternatives in the Level 2 screening process based on the potential to result in direct or indirect impacts to historic and archaeological resources. Those alternatives that would result in no impacts or minimal impacts to these resources were considered to be more prudent than those alternatives that would result in a greater amount of impacts. Alternatives that were retained through the Level 2 screening process were considered to be the most feasible, possible, prudent, and reasonable alternatives to the proposed project and were retained by the FAA for further detailed environmental evaluation in Chapter 5.0, Environmental Consequences, of this DEIS. 3.3 ALTERNATIVES CONSIDERED The following sections describe the numerous alternatives that FAA evaluated within this DEIS. The discussion of alternatives briefly describes those alternatives that were considered by the FAA but were eliminated through the Level 1 and 2 screening process, as well as those alternatives that do fulfill the purpose and need and which were examined in more detail. 3.3.1 OFF-SITE ALTERNATIVES As part of the alternatives evaluation process, FAA examined several off-site alternatives for their potential to meet the purpose and need criteria for the proposed project. These alternative concepts included development of a new airport, and the use of other existing airports. The following presents the results of FAA's evaluation of these alternative concepts. 3.3.1.1 Development of a New Airport This alternative concept consists of developing a new airport or "greenfield" site as an alternative to the proposed project at PTIA. A detailed evaluation of "greenfield" sites was not conducted in any of the recent PTIA Master Plan studies. The results of FAA's analysis indicate that development of a new airport would not satisfy project requirements. While a new airport could be designed expressly for the Level 1 airfield configuration, the Level 2 criteria - including infrastructure and cost -would be prohibitive. A "greenfield" site would require substantial investment and time to provide the infrastructure required to support a major airport such as that needed for the air cargo hub. The drawbacks and areas of concern associated with a "greenfield" site include, but are not limited to: operational authority to move aircraft operations, the development cost of the new facility, development cost of new infrastructure, access to highways and mass transit facilities, availability of a sponsoring organization (such as a local government or airport authority), community acceptance, financial feasibility, environmental impacts, potential airspace conflicts, and the willingness of the hub operator to locate there. Some of these items may be of concern at PTIA and other existing airports, but all of them would have to be resolved at a "greenfield" site. \\c1nt01\wp_wpro\PIEDMONT1DEIS\Ch_3\Ch_3.doc\3/23/00 3-11 Section 3.0 Alternatives In addition, the air cargo hub operator has not expressed an interest in developing the overnight, express air cargo hub at a "greenfield" site, or at any facility other than PTIA, and no sponsoring authority has indicated an interest in developing a new airport site. Therefore, FAA has determined that construction/development of a new airport as an alternative to the proposed project at PTIA is not a reasonable alternative and this alternative concept was not retained for further consideration in this DEIS. 3.3.1.2 Use of Other Existing Airports No competing proposals to establish an overnight air cargo hub in the Southeast have been presented to the FAA. While this limits the scope of the alternatives that might practically be expected to be accomplished, the FAA recognizes that there are other airports in the region that might accommodate an overnight, express air cargo hub. Therefore, the FAA evaluated this potential alternative within this DEIS. This alternative concept envisions the use and/or expansion of an existing airport as an alternative to the proposed project at PTIA. The development of other existing airport sites was not considered in any of the recent PTIA Master Plan studies, but it was considered by the air cargo operator when it was considering potential locations for its air cargo hub. (The operator has not made available to the FAA its detailed analyses of the other airport sites it considered before selecting PTIA for its proposed hub, and its data are not part of this EIS). FAA has independently evaluated this alternative concept in this DEIS by reviewing seven existing general aviation airports in the Triad area and five existing air carrier airports within North and South Carolina. The results of FAA's evaluation of this alternative concept indicate that the use of another existing airport (whether general aviation or air carrier) is not a reasonable alternative to the proposed project at PTIA. None of the airports met both the Level 1 and Level 2 alternatives screening process. The following provides a discussion of the FAA's evaluation of each airport, using the Level 1 and 2 criteria. General Aviation Airports - This alternative concept consists of the use/expansion of an existing general aviation airport within the twelve county Triad area. If all projected air cargo hub traffic were transferred to another airport, the airport would require airside and landside infrastructure capable of handling 48 nightly air cargo aircraft operations by the year 2005 (24 arrivals and 24 departures) and 126 nightly air cargo aircraft operations by the year 2009 (63 arrivals and 63 departures). These operational levels would have to be accommodated within the push-back-to-wheels-up and departure window time limits established by the air cargo hub operator. In other words, the air cargo aviation activity forecasts, airfield configuration, facility requirements and critical operational timing for an alternative airport would presumably be identical to what PTIA has identified. The following is a brief description of each of the alternative general aviation airports considered in the alternatives analysis. The location of each of these airports is depicted on Figure 3.3.1-1. Smith Reynolds Airport - Smith Reynolds Airport (INT) is located in Forsyth County, North Carolina approximately 3 miles northeast of the City of Winston-Salem and approximately 30 miles from PTIA. The airport encompasses approximately 702 acres of land, and is owned and operated by the Airport Commission of Forsyth County. INT has been designated by the FAA as a "primary commercial service" W:\PIEDMONT\DEIS\Ch_3\Ch_3.doc\3/24/00 3-12 Section 3.0 Alternatives airport and it has two runways in a perpendicular, intersecting configuration. The primary runway, Runway 15/33 is a grooved asphalt, air transport category runway in good condition. Runway 15/33 is 6,655 feet long and 150 feet wide with High Intensity Runway Edge Lights (HIRLs) and a Short Simplified Approach Lighting System with Runway Alignment Indicator Lights (SSLAR) on the Runway 33 end. The secondary runway, Runway 4/22, is a grooved asphalt, utility category runway in good condition. Runway 4/22 is 3,938 feet long and 150 feet wide with Medium Intensity Runway Edge Lights (MIRLs). INT does not have passenger terminal facilities or cargo facilities. The closet highway to INT is 1-40, which is approximately 5 miles away. The 1998 TAF lists INT as having 92 total based aircraft, 67,544 annual operations and 11,753 total enplanements. As described above in the introduction to Section 3.3.1.2, development of this alternative airport site would not meet the Level 1 Purpose and Need screening criteria without at least one new runway and a major runway extension and new cargo handling facilities. In addition, significant infrastructure improvements far beyond those that would be required if the proposed project were implemented at PTIA would be needed. The magnitude of improvements and their associated affects would approach those needed at a "greenfield" site, as discussed in Section 3.3.1.1. For these reasons, this alternative site was not retained for further consideration in the DEIS. Asheboro Municipal Airport - Asheboro Municipal Airport (W44) is located in Randolph County, North Carolina approximately 6 miles southwest of the City of Asheboro and approximately 29 miles from PTIA. The airport encompasses approximately 155 acres of land, is owned and operated by the City of Asheboro, and is designated by the FAA as a "general aviation" airport. W44 has one runway, Runway 3/21, which is a grooved asphalt, utility category runway in good condition. Runway 3/21 is 5,001 feet long and 75 feet wide with Medium Intensity Runway Lights (MIRLs). W44 does not have passenger terminal or cargo facilities, and the closest major highway is 1-40, which is located approximately 20 miles away. The 1998 TAF lists W44 as having 29 total based aircraft, 15,300 annual operations and 0 enplanements. This alternative airport site would not meet the Level 1 Purpose and Need screening criteria without at least one new runway and a major runway extension and new cargo handling facilities. In addition, significant infrastructure improvements far beyond those that would be required if the proposed project were implemented at PTIA would be needed. The magnitude of improvements and their associated affects would approach those needed at a "greenfield" site, as discussed in Section 3.3.1.1. For these reasons, Asheboro Municipal Airport was not retained for further consideration in the DEIS. Burlington-Alamance Regional Airport - Burlington-Alamance Regional Airport (BUY) is located in Alamance County, North Carolina, approximately 3 miles southwest of the City of Burlington and approximately 21 miles from PTIA. The airport encompasses approximately 300 acres of land, is owned and operated by the City of Burlington, and is designated as a "general aviation" airport by the FAA. BUY has two perpendicular, intersecting runways. The primary runway, Runway 6/24, is a grooved asphalt, utility category runway in good condition. Runway 6/24 is 5,000 feet long and 100 feet wide with MIRLs. The secondary runway, Runway 10/28, is a grooved asphalt, utility runway in good condition that is 2,997 feet long and 100 feet wide. BUY does not have passenger terminal facilities or cargo facilities, and the closest major roadway is 1-40, which is located approximately 3 miles away. The 1998 TAF lists BUY as having 75 total based aircraft, 40,340 total annual operations and 0 enplanements. Development of this alternative airport site would not meet project criteria as to runway length or location, or as to cargo W:\PIEDMONT\DEIS\Ch_3\Ch_3.doc\3/24/00 3-13 Section 3.0 Alternatives handling facilities. Since the use of Burlington-Alamance Regional Airport did not meet the screening criteria, this alternative site was not retained for further consideration in the DEIS. Elkin Municipal Airport - Elkin Municipal Airport (ZEF) is located in Yadkin County, North Carolina, approximately 3 miles northeast of the City of Elkin and approximately 76 miles from PTIA. The airport encompasses approximately 91 acres of land, is owned and operated by the Town of Elkin and is designated as a "general aviation" airport by the FAA. ZEF has one runway, Runway 7/25, which is a grooved asphalt, utility category runway in good condition. Runway 7/25 is 4,003 feet long and 75 feet wide with MIRLs. ZEF does not have passenger terminal facilities or cargo facilities, and the closest major highway is 1-77, which is located approximately 3 miles away. The 1998 TAF lists ZEF as having 21 total based aircraft, 15,350 annual operations and 0 enplanements. As above, this alternative airport site would not meet all of the screening criteria. Since the use of Elkin Municipal Airport did not meet the screening criteria, this alternative site was not retained for further consideration in the DEIS. Mount Airy/Surry County Airport - Mount Airy/Surry County Airport (MWK) is located in Surry County, North Carolina, approximately 3 miles southeast of the City of Mount Airy and approximately 68 miles from PTIA. The airport encompasses approximately 144 acres of land, is owned and operated by the City of Mount Airy and the County of Surry, and is designated as a "general aviation" airport by the FAA. MWK has one runway, Runway 18/36, which is a grooved asphalt, utility category runway in good condition. Runway 18/36 is 4,300 feet long and 75 feet wide with MIRLs. MWK does not have passenger terminal facilities or cargo facilities, and the closet major highway is 1-40, which is approximately 65 miles away. The 1998 TAF lists MWK as having 34 total based aircraft, 17,100 annual operations and 0 enplanements. Development of this alternative airport site would not meet the screening criteria, including lack of required runway length and lack of ground-side facilities. Since the use of Mount Airy/Surry County Airport did not meet the screening criteria, this alternative site was not retained for further consideration in the DEIS. Rockingham County-Shiloh Airport - Rockingham County-Shiloh Airport (NC14) is located in Rockingham County, North Carolina, approximately 8 miles northwest of the City of Reidsville and approximately 86 miles from PTIA. The airport encompasses approximately 220 acres of land, is owned and operated by Rockingham County, and is designated as a "general aviation" airport by the FAA. NC14 has one runway, Runway 13/31, which is a grooved asphalt, utility category runway in fair condition. Runway 13/31 is 5,199 feet long and 100 feet wide with MIRLs. NC14 does not have passenger terminal facilities or cargo facilities, and the closest major highway is 1-40, which is approximately 85 miles away. The 1998 TAF lists NC14 as having 43 total based aircraft, 20,500 annual operations and 0 enplanements. Development of this alternative airport site would not meet the screening criteria. Since the use of Rockingham County-Shiloh Airport did not meet the screening criteria, this alternative site was not retained for further consideration in the DEIS. Montgomery County Airport - Montgomery County Airport (43A) is located in Montgomery County, North Carolina, approximately 3 miles northeast of the City of Winston-Salem downtown area and approximately 50 miles from PTIA. The airport encompasses approximately 65 acres of land, is owned and operated by Montgomery County, and is designated as a "general aviation" airport by the FAA. 43A has one runway, \\clnt0l\wp_wpro\PIEDMONTDEIS\Ch_3\Ch_3.doc\3/23/00 3-14 Section 3.0 Alternatives Runway 3/21, which is a grooved asphalt, utility category runway in good condition. Runway 3/21 is 3,500 feet long and 60 feet wide with MIRLs. 43A does not have passenger terminal facilities or cargo facilities, and the closest major highway is 1-40, which is located approximately 47 miles away. The 1998 TAF lists 43A as having 9 total based aircraft, 2,700 annual operations and 0 enplanements. Development of this alternative airport site would require at least one new runway and a major runway extension, as well as new ground-side buildings, therefore, it does not meet the screening criteria. Since the use of Montgomery County Airport did not meet the screening criteria, this alternative site was not retained for further consideration in the DEIS. Summary of Use of Existing General Aviation Airports Within the Triad - The above discussed general aviation airport alternative concept only partially meets the Level 1 screening criteria, and generally fails to meet any of the Level 2 criteria. None of these airports have air transport category runways of sufficient length, and none have a parallel runway system. None of these airports currently owns or has easy access to enough acreage to accommodate the 300-acre cargo handling facility requirement. Most of these airports do not have easy access to existing infrastructure or close proximity to the interstate highway system. Although development of an existing general aviation airport would help implement Federal transportation policies, none of the alternative airports could be developed to provide the required airside and landside infrastructure within a reasonable timeframe to accommodate the needs of the air cargo operator. In addition, development of these facilities would have implications similar to those previously described in the evaluation of the development of a new "greenfield" site (see Section 3.3.1.1). These considerations include factors such as increased costs, environmental impacts, airspace constraints, and the overall inability to fulfill the Purpose and Need criteria. In addition, the separation of commercial aviation services between two closely co-located airport facilities (PTIA and any of the general aviation airports) would create an "economies of scale" problem for the smaller facility because basic services for maintenance, airport rescue and fire-fighting, postal services, administration, etc., would need to be duplicated. The economic feasibility of providing these services would be harder to achieve than at a larger, more fully developed facility since the basis over which the costs would be distributed (passengers, aircraft operations, lease space, etc.) would be smaller. Although several existing general aviation airport sites were identified in the region, none, individually or collectively, is capable of adequately accommodating the operational requirements of the air cargo hub and the PTIA. Each existing general aviation airport fulfills its own unique role and is an important part of the region's aviation system. These airports in the Triad serve general aviation aircraft traffic. Shifting air cargo operations to these airports would significantly change the basic role of the individual airports, potentially decrease available general aviation capacity at each facility, and introduce additional or higher levels of noise and other social/environmental impacts to areas not currently experiencing these types of impacts. On the basis of these considerations, the development of an existing general aviation airport facility was not considered a reasonable alternative to the proposed project at PTIA, and this concept was not retained for further consideration by the FAA in this DEIS. \\clnt0l\wp_wpro\PIEDMONTDEIS\Ch_3\Ch_3.doc\3/23/00 3-15 Section 3.0 Alternatives Air Carrier Airports Within North and South Carolina - This alternative concept consists of the use/expansion of an existing air carrier airport within North or South Carolina as an alternative to the proposed project at PTIA. Based on information provided by the PTAA, FedEx evaluated the location of the proposed air cargo hub within these two states based on several considerations, including the following: • The hub had to be located on the East Coast of the United States to serve the projected market area; • The hub had to be located so that its market service area was located within a single time- zone; • The hub had to be in a central north-south location within the projected East Coast market area; • The hub had to be located in an area of moderate weather patterns to reduce the likelihood of interruption of service due to adverse weather. After selecting the general geographic location for the hub, the air cargo operator issued a request for Proposals (RFP) in November 1997 to air carrier certificated airports within the states of North and South Carolina. Those airports that had an interest in the development of the air cargo hub responded to the RFP with proposals describing how the individual airport could accommodate the hub's facility requirements. Between February, 1998 and April, 1998, the air cargo hub operator undertook a detailed evaluation of each of the proposals as part of its site selection study. According to FedEx, the site selection study evaluated numerous criteria at each airport including the following: • Airport Operations - Runway configuration, runway lengths, instrument approaches, airfield capacity, runway accessibility, airspace and air traffic control (ATC) constraints, noise and operational concerns, weather history, and aircraft rescue and fire fighting availability. • Site Selection - Site layout, topography, environmental considerations, site access, utilities, airport services provided, construction restrictions, and responses to the request for proposals. • Financial Analysis - System form expenses, properties and facilities expenses, salaries and benefits, and taxes and incentives. The air cargo operator selected PTIA in April, 1998, for the site of its proposed overnight, express air cargo hub because PTIA was the top-rated airport in the following selection criteria, which were considered to be important by the air cargo operator. According to the air cargo operator, none of the other airports were competitive with PTIA in all of these criteria. • Space required for the development of the size of the facility and aircraft apron proposed by the air cargo hub operator, • Attractive low land lease rate, • Ability and agreement to develop parallel runways, \\ctnt0l\wp_wpro\PIEDMONTIDEIS\Ch_3\Ch_3.doc\3/23/00 3-16 Section 3.0 Alternatives • Ideal hub site location between existing and future parallel runways, • Ability to operate head-to-head aircraft operations (to and from the same direction), thereby reducing taxi times, • No competition for runway use during hub arrival and departure times, • Good interstate access, • No unexpected unresolvable environmental problems, • Outstanding incentive package, and • Operationally centered for proposed hub operations. As part of the alternatives analysis process for the DEIS, the FAA requested copies of both the air cargo operator's RFP and the individual responding airport sponsors' proposals. Detailed information on the selection process was considered confidential by the air cargo operator, and was not made available to the FAA. However, the FAA was provided with the names of the other airports that responded to the RFP. For the DEIS, the FAA made a decision to limit the alternative air carrier airports examined to the five interested airports in North and South Carolina, because their interest suggested that such a project was actually possible at those sites (note that as of this date, none of these airports has applied to the FAA for either ALP or funding approval for improvements similar to those proposed by PTAA). The FAA did not believe it would be prudent or reasonable to examine alternative airports that themselves had not expressed interest in locating a cargo hub at their airports. Therefore, the following discussion of alternative air carrier airports is limited to those five air carrier airports that expressed an interest in developing the hub. As previously discussed in the evaluation of a new airport alternative and the development of an existing general aviation airport, if all projected air cargo hub traffic were transferred to another airport, the airport would require airside and landside infrastructure capable of handling 48 nightly air cargo aircraft operations by the year 2005 (24 arrivals and 24 departures) and 126 nightly air cargo aircraft operations by the year 2009 (63 arrivals and 63 departures). Furthermore, these operational levels would have to be accommodated within the push-back-to-wheels-up and departure window time limits established by the air cargo hub operator. In other words, the air cargo aviation activity forecasts, airfield configuration, facility requirements, and critical operational timing for an alternative airport would presumably be identical to those identified by PTIA. The following provides a brief description of the existing air carrier airports in North and South Carolina that were evaluated by the FAA in this DEIS as potential alternatives to the proposed project at PTIA, and the FAA's findings associated with each of these alternative airports. The FAA used Level 1 screening criteria described earlier to assess these airports. The location of these airports is depicted in Figure 3.3.1-2. North Carolina Global Transpark - North Carolina Global Transpark (ISO) is located in Lenoir County, North Carolina approximately 3 miles northwest of the City of Kinston and approximately 153 miles from W:\PIEDMONT\DEIS\Ch_3\Ch_3.doc\3/24/00 3-17 Section 3.0 Alternatives PTIA. The airport encompasses approximately 1,255 acres of land, is owned and operated by the North Carolina Global Transpark Authority, and is designated as a "primary commercial service" airport by the FAA. ISO has one runway, Runway 5/23, which is a grooved asphalt, air transport category runway in good condition. Runway 5/23 is 8,600 feet long and 150 feet wide with HIRLs and a MALSR. This runway is currently being extended to 10,600 feet. ISO has both passenger terminal facilities and cargo facilities. The closest major highway is 1-95, which is located approximately 30 miles away. The 1998 TAF lists ISO as having 43 total based aircraft, 36,475 annual operations and 10,434 total annual enplanements. Review of this alternative airport indicates that ISO partially meets the Level 1 screening criteria. This alternative would require the construction of a new widely spaced parallel 9,000 foot Transport Category runway that would allow for the ability to conduct dual simultaneous independent IFR operations. ISO is located approximately 30 miles from the nearest major highway, therefore it would not provide sufficient surface transportation infrastructure to meet the air cargo operator's requirements to have proximate access to an established, diverse roadway network. The purpose of the proposed project is to develop an overnight, express air cargo hub at PTIA. ISO as an alternative to the proposed project at PTIA does not meet the Level 1 screening criteria for runway redundancy or runway configuration, and it does not meet the Level 1 hub operational requirement. In addition, the recent EIS completed by the FAA for the Transpark found potential environmental impact issues that would require additional analysis before further improvements could be considered The FAA does not consider ISO a reasonable alternative to the proposed project at PTIA, and it was not retained for further consideration in the DEIS. Raleigh-Durham International Airport - Raleigh-Durham International Airport (RDU) is located in Wake County, North Carolina approximately 9 miles northwest of the City of Raleigh and approximately 52 miles from PTIA. The airport encompasses approximately 4,770 acres of land, is owned and operated by the Raleigh-Durham Airport Authority, and is designated as a "primary commercial service" airport by the FAA. RDU has two parallel runways and one perpendicular runway. The primary runway, Runway 5L/23R is a grooved concrete, air transport category runway that is 10,000 feet long and 150 feet wide with HIRLs and a MALSR. Runway 5R/23L is a grooved asphalt, air transport category runway that is 7,500 feet long and 150 feet wide with HIRLs and a MALSR. Runways 5L and 5R have a 3,500 foot centerline-to-centerline separation, which provides the ability to conduct dual simultaneous independent IFR operations. Runway 14/32 is an asphalt, utility category runway that is 3,700 feet long and 100 feet wide with MIRLs. RDU has passenger terminal facilities and cargo facilities. The closest major roadway is 1-40 that is approximately 3 miles from RDU. The 1998 TAF lists RDU as having 246 total based aircraft, 245,236 annual operations and 3,341,832 annual enplanements. Review of this alternative airport indicates that Raleigh-Durham International Airport partially meets the Level 1 screening criteria. Although RDU provides widely spaced parallel runways with sufficient separation to allow dual simultaneous independent IFR operations, it does not provide redundant 9,000 foot air Transport Category runways. Existing Runway 5R/23L would have to be extended 1,500 feet to a total length of 9,000 feet in order for RDU to accommodate the airside operational requirements of the air cargo hub. In addition, RDU could not provide sufficient land area located between the parallel runways to \\clnt0l\wp_wpro\PIEDMONT\DEIS\Ch_3\Ch_3.doc\3/23/00 3-16 Section 3.0 Alternatives develop the sort/distribution facilities needed for the air cargo hub without extensive relocation of existing facilities. These relocated facilities would include the existing cargo terminals, Park & Ride Lots 2 and 4, general aviation facilities, Observation Park, and relocation of International Drive and part of Commerce Boulevard. RDU would have to implement an extensive land acquisition and relocation program and have all of this existing infrastructure relocated prior to initiation of construction of the sorting/distribution facility. The purpose of the proposed project is to develop an overnight, express air cargo hub at PTIA. The FAA has not received a proposal from RDU to develop facilities that would meet the operational requirements of a proposed air cargo hub facility. Since the use of RDU as an alternative to the proposed project at PTIA does not meet all of the Level 1 screening criteria, the FAA does not consider RDU a reasonable alternative to the proposed project at PTIA, and it was not retained for further consideration in the DEIS. Greenville-Spartanburg International Airport - Greenville-Spartanburg International Airport (GSP) is located in Greenville County, South Carolina, approximately 3 miles south of the City of Greer and approximately 178 miles from PTIA. The airport encompasses approximately 2,700 acres of land, is owned and operated by the Greenville-Spartanburg Airport Commission, and is designated as a "primary commercial service" airport by the FAA. Greenville-Spartanburg International Airport has one runway, Runway 4/22 which is a grooved concrete/asphalt, air transport category runway that is 11,000 feet long and 150 feet wide with HIRLs, an Approach Lighting System with Sequenced Flashers - Category II (ALSF-2) on the Runway 3 end and a MALSR on the Runway 21 end. GSP has passenger terminal facilities and cargo facilities. The closest major roadway is 1-85, located within 1 mile of the south boundary of the airport property. The 1998 TAF lists GSP as having 24 total based aircraft, 64,180 annual operations and 781,706 annual enplanements. Review of this alternative airport indicates that GSP partially meets the Level 1 screening criteria. GSP does not have widely spaced parallel runways with sufficient separation to allow dual simultaneous independent IFR operations, and it does not provide redundant 9,000 foot air transport category runways. A new 9,000 foot Transport Category runway parallel to existing Runway 4/22 would have to be constructed in order for GSP to accommodate the airside operational requirements of the air cargo hub. In order to provide sufficient land area located between the parallel runways to develop the sort/distribution facilities needed for the air cargo hub, relocation of existing facilities and roadway infrastructure would have to occur. The extent of relocations required would vary depending on the location of the sorting/distribution facility. Since GSP is located near a major highway and has well developed surface transportation infrastructure, it does meet the air cargo operator's surface transportation infrastructure requirements to have proximate access to an established, diverse roadway network. The purpose of the proposed project is to develop an overnight, express air cargo hub at PTIA. Since the use of GSP as an alternative to the proposed project at PTIA does not meet all of the Level 1 screening criteria, the FAA does not consider GSP a reasonable alternative to the proposed project at PTIA, and it was not retained for further consideration in the DEIS. Columbia Metropolitan Airport - Columbia Metropolitan Airport (CAE) is located in Lexington County, South Carolina, approximately 5 miles southwest of the City of Columbia and approximately 178 miles \\clnt01\wp_wpr0\PIEDMONl1DEIS\Ch_3\Ch_3.doc\3/23/00 3-19 Section 3.0 Alternatives from PTIA. The airport encompasses approximately 2,558 acres of land, is owned and operated by Richland/Lexington County, and is designated as a "primary commercial service" airport by the FAA. CAE has two intersecting runways. The primary runway, Runway 11/29 is a grooved asphalt, air transport category runway that is 8,602 feet long and 150 feet wide with HIRLs, an ALSF-2 on the Runway 11 end and a MALSR on the Runway 29 end. The secondary runway, Runway 5/23 is a grooved asphalt- concrete, air transport category runway that is 8,000 feet long and 150 feet wide with HIRLs and a MALSR on the Runway 5 end. CAE has passenger terminal facilities and cargo facilities. The closest major highway is 1-26, located approximately 1 mile away. Access to the City of Columbia central business district (CBD), which is approximately 6 miles from CAE is provided via S.C. Highways 302 and 602. The 1998 TAF lists CAE as having 103 total based aircraft, 115,716 annual operations and 619,707 annual enplanements. Review of this alternative indicated that CAE partially meets the Level 1 screening criteria. This alternative airport does not provide widely spaced parallel runways with sufficient separation to allow dual simultaneous independent IFR operations and it does not have redundant 9,000 foot air Transport Category runways, both of which are needed to meet the operational requirements of the air cargo hub. Existing Runway 11/29 would have to be extended 398 feet to a total of 9,000 feet, and a new 9,000 foot widely spaced Transport Category parallel runway would have to be constructed. The level of development that would have to occur at CAE is comparable to that which is proposed at PTIA. Based on the layout of the existing airport facility and surrounding lands, it appears reasonable that the improvements needed at CAE to accommodate the airside and landside requirements of the overnight express air cargo hub could be developed. Development of CAE would help implement Federal transportation policies, and it could provide sufficient land area to develop the sort/distribution facilities needed to support the express overnight air cargo hub. CAE is located approximately 1 mile from the nearest major highway, and it has good surrounding surface transportation infrastructure, therefore it does meet air cargo hub's surface transportation requirements to have proximate access to an established, diverse roadway network. The purpose of the proposed project is to develop an overnight, express air cargo hub at PTIA. Although CAE as an alternative to the proposed project at PTIA meets several of the Level 1 screening criteria, its lack of Level 1 parallel runway configuration and redundant runways caused the FAA to eliminate CAE a reasonable alternative to the proposed project at PTIA, and it was not retained for further consideration in the DEIS. Charlotte/Douglas International Airport - Charlotte/Douglas International Airport (CLT) is located in Mecklenburg County, North Carolina approximately 4 miles west of the City of Charlotte and approximately 94 miles from PTIA. The airport encompasses approximately 5,000 acres of land, is owned and operated by the City of Charlotte, and is designated as a "primary commercial service" airport by the FAA. Charlotte/Douglas International Airport has two parallel runways and one crosswind runway. The primary runway, Runwayl8R/36L is a concrete, air Transport Category runway that is 10,000 feet long and 150 feet wide with HIRLs, a MALSR on the Runway 18R end and an ALSF-2 on the Runway 36L end. The secondary runway, Runway 18U36R is a grooved asphalt-concrete, air Transport Category runway that is 8,845 feet long and 150 feet wide with HIRLs and an ALSF-2 on the Runway 36R end. Runways W:\PIEDMONT\DEIS\Ch_3\Ch_3.doc\3/24/00 3-20 Section 3.0 Alternatives 18R and 18L have a 5,000 foot centerline-to-centerline separation, which provides the ability to conduct dual simultaneous independent IFR operations. Crosswind Runway 5/23 is a grooved asphalt-concrete, air Transport Category runway that is 7,500 feet long and 150 feet wide with HIRLs and a MALSR on the Runway 5 end. Charlotte/Douglas International Airport has passenger terminal facilities and cargo facilities. The closest major highways are 1-85, which is approximately 1.5 miles to the north, and 1-77, which is approximately 5 miles to the east. The 1998 TAF lists CLT as having 174 total based aircraft, 451,190 annual operations and 1,327,556 annual enplanements. Review of this alternative indicates that CLT partially meets the Level 1 screening criteria. CLT provides widely spaced parallel runways, but it does not provide redundant 9,000 foot air Transport Category runways. Existing Runway 18L/36RL would have to be extended 155 feet to a total length of 9,000 feet in order for CLT to provide redundant 9,000 foot air transport category runways. CLT would be able to provide the required airside and landside infrastructure with only minor improvements to existing Runway 18L/36R. CLT is currently experiencing significant aircraft operational delays associated with both air carrier and air cargo operations. This delay was quantified in the recently completed Charlotte/Douglas International Airport Master Plan Update, Final, January 1998. The FAA has a recently completed an EIS which assessed the potential environmental impacts associated with construction of third parallel runway to accommodate existing and forecast traffic and reduce operational delay. The addition of 48 daily operations in 2005 and 128 daily operations in 2009 as a result of development of the Mid-Atlantic Hub would have a significant impact on air carrier aircraft operations associated with the U.S. Airways Hub, as well as the air cargo operations associated with the UPS air cargo operation at CLT. The existing and forecast operations at CLT would have a significant affect on the proposed overnight, express air cargo hub's ability to operate in an efficient manner. The proposed overnight, express air cargo hub's aircraft would be competing with other air carrier and air cargo aircraft for approach and departure slots, as well as for taxiway and runway queuing while on the ground. The approach and departure slot conflict would prevent the proposed air cargo aircraft from operating in a "head-to-head" mode. The taxiway and runway queuing conflict on the ground would prevent the proposed air cargo operator from meeting its aircraft specific push-back-to-wheels-up operational requirements. As describe in Chapter 2.0, Purpose and Need, the ability to conduct head-to-head operations and to have unimpeded taxi/runway flow is critical to the air cargo carrier, for meeting the proposed cargo hub's departure window and push-back-to-wheels-up operational requirements. The purpose of the proposed project is to develop an overnight, express air cargo hub, and CLT meets several of the Level 1 alternatives screening criteria. If CLT submitted a competing application for the proposed project to the FAA for consideration, it would be afforded complete consideration under all NEPA categories. However, without such a proposal, and because CLT has completed the EIS process for its own new runway improvement project, the FAA does not consider CLT a reasonable alternative to the proposed project at PTIA, and it was not retained for further consideration in the DEIS. Summary of Use of Other Existing General Aviation and Air Carrier Airports - The FAA looked at existing airports to see if there were any that could accommodate air cargo hub development. As W:\PIEDMONT\DEIS\Ch_3\Ch_3.doc\3/24/00 3-21 Section 3.0 Alternatives disclosed above, the preliminary assessment showed that some of these airports could accommodate some of the physical requirements associated with the proposed project. The assessment also suggested that some airports, like PTIA, would have complicated construction, relocation, cost, and environmental factors to address. In that context, and without any local sponsor presenting a proposal to the FAA at this time, the FAA could not justify retaining any of the off-site alternatives for detailed environmental analysis in this document. 3.3.2 PTIA RUNWAYAND AlR CARGO FAciLITYALTERNAT/VES 3.3.2.1 Introduction Once FedEx selected PTIA for its Mid-Atlantic Hub, PTIA examined on-site potential development sites for a Mid-Atlantic Hub facility at PTIA, identifying and evaluating key elements of airfield and facility planning needed to meet the operational requirements of the air cargo hub. As represented to the FAA by the sponsor, these key elements included a need for redundant 9,000 foot Transport Category runways, widely spaced parallel runways that support dual simultaneous independent precision-instrument operations, functional and operational requirements for the proposed air cargo sorting and distribution facility, hub facility layout, space requirements, proximity and inter-connectivity to existing and future airfield facilities and surface transportation infrastructure, and overall time required to develop the facilities and initiate operations. To develop and operate a Mid-Atlantic Hub at PTIA, the following conditions and/or facilities (existing and/or planned on an FAA-approved Airport Layout Plan) were deemed necessary by FedEx: • Airport facilities that accommodate operational requirements including a redundant Transport-Category runway system having a minimum 9,000-foot length, and widely spaced parallel runways that support dual simultaneous independent precision-instrument operations; • A hub facility development site located between parallel runways having an approximate size of 300 contiguous acres; • Hub/runway/taxiway proximity that allows the air cargo operator to maximize meeting its critical push-back-to-wheels-up and departure window requirements; and • Ability to construct and operate Phase 1 of the development by the year 2004, and Phase 2 by the year 2009. When identifying on-site alternative locations for the development of a hub facility, technical considerations were grouped into two major categories: 1) the identification of available (or potentially available) on-airport land areas on which a sorting/distribution facility could be developed, and 2) the proximity of existing and future airfield improvements (runways, taxiways, and taxiway connectors) that are essential and required for the efficient operation of the hub. Identification of viable alternative locations on which to develop the sorting/distribution facility included review and assessment of the airport's existing runway/taxiway system, land areas, land uses, and land uses immediately adjacent to the airport. A systematic process to identify and assess the relative merits and opportunities for locations of the sorting/distribution facility and proposed parallel runway necessary for the development and operation of \\clnt0l\wp_wpro\PIEDMONT\DEIS\Ch_3\Ch_3.doc\3/23/00 3-22 Section 3.0 Alternatives the overnight, express air cargo hub examined a total of five potential hub development sites and eight potential runway locations. This process yielded 40 possible alternative runway-sort/distribution facility scenarios which are described in this section of the DEIS and depicted in Figure 3.3.2-1. Two additional alternative scenarios submitted by an interested group of citizens during Scoping for this DEIS and the airport sponsor were also evaluated and are described in this section of the DEIS. 3.3.2.2 Description of Runway Development Alternative Scenarios The individual runway alternatives were developed and evaluated for their ability to meet the minimum facility and operational requirements addressed in the sponsor's proposal, which stressed the need for redundant 9,000-foot Transport-Category runways, and widely spaced parallel runways that allowed for the ability to conduct dual simultaneous independent IFR aircraft operations. For the parallel runway alternative scenarios, the minimum runway centerline separation for dual simultaneous independent all- weather operations (3,400 feet) as prescribed by FAA Advisory Circular 15015300-13, Change 5, Standards and Recommendations for Airport Design was used. Those runway alternative scenarios that did not meet the operational/capacity needs of the air cargo hub operator through the year 2019 were not retained for further consideration after the Level 1 screening analysis because these alternatives did not fulfill the purpose and need for the proposed project. Those runway alternative scenarios that did meet the Level 1 purpose and need criteria were retained for additional analysis in Level 2 of the alternatives screening process. X Runway Alternative (X) - This runway alternative would consist of the lengthening of each of PTIA's two existing runways. Runway 14/32 would be extended 2,620 feet to the northwest to a total length of 9,000 feet. Runway 5/23 would be extended to a length of 10,650 feet, and the Runway 5 threshold would be relocated 1,650 feet to the northeast. The relocation of the end of Runway 5 by 1,650 feet is needed in order to physically separate the two runways while also providing positive separation from existing Runway 14/32, with provision of a standard 1,000-foot Runway Safety Area (RSA) and jet-blast protection and to remain clear of Runway 14/32 Terminal Instrument Procedures (TERPS) surfaces. This runway development alternative would provide the two required redundant Transport-Category runways having a minimum length of 9,000 feet, while also preserving the 10,000-foot length for Runway 5/23. However, this alternative would not provide the ability to conduct dual simultaneous independent IFR operations, and it would not allow for the ability to conduct head-to-head operations during times of peak air cargo operations. West 1 Runway Alternative (W1) - This runway alternative would be based on the construction of a new 9,000-foot Transport-Category runway located 4,300 feet west of, and parallel to, existing Runway 5/23. The location of the new parallel runway and in-board parallel taxiway would overlie the existing Bryan Boulevard right-of-way west of the terminal parking complex. As such, westward relocation of Bryan Boulevard would be required with slight modifications to the connecting interchanges of Regional Road and Inman Road. New dual cross-field taxiways connecting the two parallel runways would support critical aircraft movements to and from both runways and all other areas of the airport. Existing Taxiway D, which runs parallel to Runway 14/32, would be extended to serve as a south cross-field taxiway. This alternative would provide PTIA with redundant 9,000-foot Transport-Category runways, provide the ability to conduct \\c1MOI\wp_wpio\PIEDMONTDEIS\Ch_3\Ch_3.doc\3/23/00 3-23 Section 3.0 Alternatives dual simultaneous independent IFR operations, and it would allow for head-to-head operations during times of peak air cargo operations. West 2 Runway Alternative (W2) - This runway alternative is currently depicted on PTIA's ALP and consists of the construction of a new 9,000-foot Transport-Category runway located 5,488 feet west of, and parallel to, existing Runway 5/23. The location of the new parallel runway would require the construction of a tunnel for Bryan Boulevard that would traverse under the runway and the construction of two cross field taxiway bridges that would cross over Bryan Boulevard. New dual cross-field taxiways connecting the two parallel runways would support critical aircraft movements to and from both runways and all other areas of the airport. Existing Taxiway D, which runs parallel to Runway 14/32, would be extended to sere as a south cross-field taxiway. This alternative would provide PTIA with redundant 9,000-foot Transport-Category runways, provide the ability to conduct dual simultaneous independent IFR operations, and it would allow for head-to-head operations during times of peak air cargo operations. West 3 Runway Alternative (W3) - This runway alternative is similar to the West 2 Alternative in that a new 9,000-foot Transport-Category runway would be located 5,488 feet west of, and parallel to, existing Runway 5/23. The location of the new dual cross-field taxiway system would remain the same as in Alternative W2. Taxiway D would be extended to sere as a south cross-field taxiway between the two parallel runways. Under this alternative however, the runway/taxiway system of the proposed parallel runway would be shifted 1,032 feet to the southwest along the runway centerline. This shift would align the new dual north cross-field taxiway connectors with the end of the proposed parallel runway. Similar to the West 2 Alternative, the location of the new parallel runway would require the construction of a tunnel for Bryan Boulevard that would traverse under the runway and the construction of two cross-field taxiway bridges that would cross over Bryan Boulevard. This alternative would provide PTIA with redundant 9,000- foot Transport-Category runways, provide the ability to conduct dual simultaneous independent IFR operations, and it would allow for head-to-head operations during times of peak air cargo operations. East 1 Runway Alternative (E1) - This alternative would consist of the construction of a new 9,000-foot Transport-Category runway located 3,400 feet east of, and parallel to, existing Runway 5/23. The new parallel runway would be situated such that the approach surfaces of each end of the runway would have the necessary vertical clearances over Interstate 40 and the future Greensboro Western Loop Road. The runway would directly overlie U.S. 421 (West Market Street) and the adjacent Norfolk Southern Railway that runs parallel along the west side of the U.S. 421 right-of-way. Existing Taxiways A and C, which run parallel to Runway 14/32, would be extended to the southeast to interconnect the two runway systems. The existing general aviation complex east of Runway 5/23 would have direct and unimpeded access to the new runway's inboard parallel taxiway. This alternative would provide PTIA with redundant 9,000-foot Transport-Category runways, provide the ability to conduct dual simultaneous independent IFR operations, and it would allow for head-to-head operations during times of peak air cargo operations. Because of the 3,400-foot separation between the parallel runways, an advanced radar system such as a Precision Runway Monitor (PRM) would have to be installed at PTIA to allow for the ability to conduct dual simultaneous independent IFR operations. \\clnt01\wp_wpro\PIEDMOMIDEIS\Ch_3\Ch_3.doc\3/23/00 3-24 Section 3.0 Alternatives East 2 Runway Alternative (E2) - This alternative is similar to the East 1 Alternative in that the new 9,000-foot Transport-Category runway would be constructed east of, and parallel to, existing Runway 5/23. However, this alternative would have a centerline separation of 4,300 feet between the runways. The new runway would be situated such that the approach surfaces of Runway 5R would provide the necessary vertical clearances over U.S. 421 (West Market Street) and the adjacent Norfolk Southern Railway that runs parallel along the west side of PTIA as well as Interstate 40. However, the new runway would overlie the future Greensboro Western Loop Road right-of-way. The new runway would interconnect with Runway 14/32 via an offset extension to existing Taxiway C. The existing general aviation complex east of Runway 5/23 would have direct and unimpeded access to the new runway's inboard parallel taxiway. This alternative would provide PTIA with redundant 9,000-foot Transport-Category runways, provide the ability to conduct dual simultaneous independent IFR operations, and it would allow for head-to-head operations during times of peak air cargo operations. North Runway Alternative (N) - This alternative would consist of the construction of a new 9,000-foot Transport-Category runway located 7,630 feet north of, and parallel to, existing Runway 14/32. The runway would be situated such that the approach surface of future Runway 32R would have the necessary vertical clearances over the future Greensboro Western Loop Road right-of-way. The location of the new parallel runway would require the construction of a tunnel for Bryan Boulevard that would traverse under the runway and the construction of two cross field taxiway bridges that would cross over Bryan Boulevard. The new parallel runway would have a full-length parallel taxiway on the south side to allow unrestricted access to and from the existing terminal and general aviation complex. Under this alternative, existing Runway 14/32 would be extended 2,620 feet to the northwest to a total length of 9,000 feet, and existing parallel Taxiway C would be extended to a length of 9,000 feet. Taxiway A would also be widened and extended. This alternative would provide PTIA with redundant 9,000-foot Transport-Category runways, provide the ability to conduct dual simultaneous independent IFR operations, and it would allow for head- to-head operations during times of peak air cargo operations. South Runway Alternative (S) - This alternative would consist of the construction of a new Transport- Category runway located 3,400 feet south of, and parallel to, existing Runway 14/32. The location of the new parallel runway and in-board parallel taxiway would overlie Regional Road, 1-40, U.S. 421, and the Norfolk Southern Railway right-of-ways. The construction of three cross field taxiways to interconnect the two parallel runways would be required to provide unrestricted access to the two parallel runways from the terminal and east general aviation complex. This alternative would provide PTIA with redundant 9,000- foot Transport-Category runways, provide the ability to conduct dual simultaneous independent IFR operations, and it would allow for head-to-head operations during times of peak air cargo operations. Because of the 3,400-foot separation between the parallel runways, an advanced radar system such as a Precision Runway Monitor (PRM) would have to be installed at PTIA to allow for the ability to conduct dual simultaneous independent IFR operations. Citizens Scoping Runway Alternative - A runway-sorting/distribution facility alternative concept was submitted by a group of interested citizens during Scoping for the DEIS. The citizens runway alternative concept would extend Runway 14/32 by 2,620 feet to the west for a total length of 9,000 feet; relocate the threshold of Runway 5 by 700 to 1,000 feet; extend the end of Runway 23 by 700 to 1,000 feet, and \\clnt0l\wp_wpro\PIEDMONTDEIS\Ch_3\Ch_3.doc\3/23/00 3-25 Section 3.0 Alternatives provide a high speed exit taxiway from Runway 5/23 to the south side of Runway 14/32. This runway alternative concept would provide two redundant Transport-Category runways having a minimum length of 9,000 feet, while also preserving the 10,000-foot length for Runway 5/23. However, this alternative would not provide the ability to conduct dual simultaneous independent IFR operations, or the ability to conduct head-to-head operations during times of peak air cargo operations. W1-1 Runway Alternative - In August 1999, the PTAA requested that the FAA consider in the DEIS an additional "west" parallel runway alternative that was developed by the PTAA as a result of detailed planning efforts associated with the ongoing PTIA Master Plan Update. Under this alternative, the centerline separation distance between the proposed new parallel runway and existing Runway 5/23 would be 5,088 feet, and the threshold of the end of new Runway 23R would be shifted approximately 1,032 feet to the southwest, the same as in Runway Alternative W3. The 5,088 foot separation distance between the parallel runways associated with this runway alternative would result in a need to relocate a 2-mile segment of Bryan Boulevard to the west of its current location. A new interchange for Bryan Boulevard and Old Oak Ridge Road would also need to be developed. 3.3.2.3 Description of Air Cargo Sorting/Distribution Facility (FedEx Mid-Atlantic Hub) Site Alternative Scenarios Five potential site alternatives that would meet the size and geometric requirements (a site having a rectangular shape with approximately 300 contiguous acres) were identified and evaluated. Each alternative site location was based solely on the required size, geometry, and relative proximity to existing or planned airport and surface transportation facilities. Each site possessed unique attributes and opportunities with respect to meeting the proposed air cargo sorting and distribution facility requirements as presented by the sponsor. The following provides a description of the five alternative development sites, which are also depicted in Figure 3.3.2-1. Site A Alternative (A) - Site A is located northwest of and adjacent to existing Runway 5/23, in the northwest quadrant of the airport. The site is wholly owned by the PTAA, is currently undeveloped and is designated on PTIA's conditionally approved Airport Layout Plan (ALP) as being reserved for future commercial/cargo development. The site is bounded by existing cargo facilities to the south, existing Runway 5/23 to the east, Bryan Boulevard to the west, and Old Oak Ridge Road/Bryan Boulevard to the north. Site B Alternative (B) - Site B is located northeast of and adjacent to existing Runway 5/23 in the northeast quadrant of the airport. The site partially encompasses airport owned leased areas for existing commercial and general aviation-related facilities which are located east of existing Runway 5/23 and north of existing Runway 14/32. The remaining portions of this site would have to be acquired by or leased to PTIA in order to develop the sorting/distribution facility. The site is bounded by the planned Greensboro Western Loop Road right-of-way to the east, existing Runway 5/23 to the west, the existing commercial aviation developments to the south, and Old Oak Ridge Road to the north. PTIA's conditionally approved ALP does not designate this area for future airport related development. \\clnt0l\wp_wpro\PIEDMOMIDEIS\Ch_3\Ch_3.doc\3/23/00 3-26 Section 3.0 Alternatives Site C Alternative (C) - Site C is located southwest of and adjacent to existing Runway 14/32 and west of the approach end of existing Runway 5. The site is partially within the current airport property boundaries. The remaining portions of this site would have to be acquired by or leased to PTIA in order to develop the sorting/distribution facility. The site encompasses a variety of commercial/industrial-developed parcels, U.S. 421, portions of the Norfolk Southern Railway, Regional Road, and the main BellSouth switching station. PTIA's conditionally approved ALP designates the portion of this site within the existing airport property boundaries as a "Future Aviation Development Area" and Runway Protection Zone (RPZ) for future Runway 51/23R. Site D Alternative (D) - Site D is located due west of the airport and is generally bounded by Regional Road to the south, Caindale Drive to the north, commercially developed and vacant lands to the west, and undeveloped PTIA property/Bryan Boulevard to the east. The site completely encompasses a platted corporate-style office park development and facilities along Bentley Road, Business Park Drive and Skyway Drive. PTIA's conditionally approved ALP designates portions of this site within the existing airport property boundaries for both future parallel runway development and "Future Aviation Development Area". The remaining portions of this site would have to be acquired by or leased to PTIA in order to develop the sorting/distribution facility. Site E Alternative (E) - Site E is located southeast of existing Runway 5/23 and northeast of existing Runway 14/32 in the southeast quadrant of the airport. This alternative is a variant of Site B and is located northeast of and adjacent to existing Runway 5/23 in the east quadrant of the airport, on mostly airport owned property. The portions of this site located outside the existing boundaries of PTIA would have to be acquired by or leased to PTIA in order to develop the sorting/distribution facility. The site completely encompasses the extent of the commercial and general aviation-related leased areas of the airport on the southeast side of existing Runway 5/23. The site is bounded by the planned Greensboro Western Loop Road right-of way to the east, existing Runway 5/23 to the west, and the developed commercial aviation areas to the south. The southernmost extent of the site is adjacent to existing Runway 14/32 and parallel to Taxiway C. PTIA's conditionally approved ALP does not designate this area for any future airport related development. Citizens Scoping Sorting/Distribution Facility Alternative - A sorting/distribution facility site alternative was submitted to the FAA by a group of interested citizens during Scoping for this DEIS. This alternative site would place the sorting/distribution facility on approximately 300 acres of land located south of Runway 14/32, between Runway 14/32 and US Highway 421 (West Market Street) and NC Highway 68 (Regional Road). The site encompasses a variety of commercial/industrial-developed and residential parcels, as well as portions of existing airport property. PTIA's conditionally approved ALP designates the portion of this site within the existing airport property boundaries as a "Future Aviation Development Area" and "Runway Protection Zone" (RPZ) for the proposed future parallel Runway 5L/23R. The portions of this site located outside the existing boundaries of PTIA would have to be acquired by or leased to PTIA in order to develop the sorting/distribution facility. \\clnt0l\wp_wpro\PIEDMONT\DEIS\Ch_3\Ch_3.doc\3/23/00 3-27 Section 3.0 Alternatives 3.3.3 EVALUATION OF PTIA RUNWAY AND SORTING/DISTRIBUTION FACILITY SITE ALTERNATIVES 3.3.3.1 Introduction The evaluation of on-site alternatives was based on an examination of each of the previously described eight potential runway configurations integrated with each of the previously described five potential sorting/distribution facility development sites. In addition, the evaluation included an alternative concept submitted by a group of citizens during Scoping and an alternative submitted by the airport sponsor after the DEIS was started. This yielded a total of 42 distinct alternative scenarios. Each of the 42 alternative development scenarios were subject to the two-level alternatives screening process to determine which alternatives were the most reasonable, feasible and prudent for detailed evaluation in this DEIS. The following is a summary of the results of the screening process for these alternatives. The discussion is presented based on each of the runway alternatives, and expanded to discuss the implications of each of the site alternatives. Table 3.3.3-1 depicts how each alternative passed through the two-level alternatives screening process. 3.3.3.2 Level 1 Screening Level 1 of the FAA's alternatives screening process evaluated each of the 42 alternative scenarios for their ability to fully satisfy all of the purpose and need criteria previously established in Chapter 2.0, Purpose and Need, of this DEIS. • Develop an air cargo sorting/distribution hub facility at PTIA; • Provide redundant 9,000-foot Transport-Category runways; • Provide the ability to conduct dual simultaneous independent IFR operations, and • Provide approximately 300 contiguous acres in a rectangular shape located between parallel runways for the development of the sorting/distribution facility. For an alternative to continue to the Level 2 analysis, it had to meet all of the Level 1 screening criteria. Those alternatives that did not meet all of the Level 1 screening criteria were not retained for further evaluation in this DEIS. No-Action Alternative - The No-Action Alternative would not meet any of the purpose and need criteria for the proposed project at PTIA. This alternative would not locate an air cargo sorting/distribution facility at PTIA, provide redundant 9,000-foot Transport-Category runways, provide the ability to conduct dual simultaneous independent IFR operations, or provide a sorting/distribution facility site that meets the operational requirements of the air cargo hub. As described in Section 2.0, Purpose and Need, the proposed improvements are needed for the air cargo operator to maximize the efficiency of its operations, particularly during the push-back-to-wheels-up and departure window timeframe. Although the No-Action Alternative did not meet the purpose and need criteria, it was retained for further consideration in Level 2 \\clnt01\wp_wpro\PIEDMOMIDEIS\Ch_3\Ch_3.doc\3/23/00 3-28 Section 3.0 Alternatives of the Alternatives screening to ensure a complete environmental impact evaluation and to provide a baseline comparison. Alternatives X-A through X-E - Runway-sort/distribution facility site Alternatives X-A through X-E would only partially meet the purpose and need criteria for the proposed project at PTIA. All of these alternatives would locate the air cargo sorting/distribution facility at PTIA, provide redundant 9,000-foot Transport- Category runways, and provide approximately 300 contiguous acres in a rectangular shape for the development of the hub facility. However, none of these alternatives would provide the ability to conduct dual simultaneous independent IFR operations, the capability to conduct head-to-head operations during times of peak air cargo operations, or develop a sorting/distribution facility site located between parallel runways. As described in Chapter 2.0, Purpose and Need, and quantified in the TAAM analysis, all three of these criteria are needed to facilitate overnight cargo hub operations, particularly during the push-back- to-wheels-up departure timeframe. The use of perpendicular runways under the Alternative X-A through X-E scenarios would result in operational conditions that would lessen the overall efficiency of aircraft operations such as dependent operations (operations on one runway affect/limit operations on the other runway) and increased runway crossings, change local and potentially regional flight patterns (more daytime and nighttime operations on Runway 14/32 in an east-west orientation as opposed to north-south orientation under existing operational conditions on Runway 5/23) and result in potential safety concerns (increased use of a designated crosswind runway and increased runway crossings) at PTIA. The development of a hub facility that is not located between parallel runways would result in the air cargo operator not being able to meet most of its designated push-back-to-wheels-up departure timeframe. Since none of these five alternatives met all of the Level 1 purpose and need criteria, none were retained for further consideration in this DEIS. Alternatives W1-A through W1-E - Runway-sort/distribution facility site Alternatives W1 -A through W1 -E would only partially meet the purpose and need criteria for the proposed project at PTIA. All of these alternatives would locate the overnight, express air cargo hub at PTIA, provide redundant 9,000-foot Transport-Category runways, provide the ability to conduct dual simultaneous independent IFR operations and provide the capability to conduct head-to-head operations during times of peak air cargo operations. However, Alternative W1-A did not meet all of the Level 1 screening criteria because the 4,300 foot centerline-to-centerline separation distance between existing Runway 5R/23L and proposed Runway 5U23R would not provide a sorting/distribution facility site of sufficient size to meet operational needs. Alternatives W1-B, W1-C, W1-D, and W 1-E did not meet the Level 1 screening criteria because they would not provide a sorting/distribution facility site located between parallel runways, which, based on the TAAM analysis, is critical to meeting the operational needs of the air cargo carrier. The location of the sort/distribution facility site associated with Alternative W 1-C does not meet FAA Standards and Recommendations for Airport Design (Advisory Circular 150/5300-13) because a portion of the proposed site (approximately 10 percent) would fall within the future RPZ of proposed parallel Runway 5U23R. FAA's design guidelines, which were developed to enhance the protection of people and property on the ground, prohibit the development of places of public assembly within a RPZ, and further recommends that it is desirable that the RPZ remain clear of all objects. The development of the sorting/distribution facility within the RPZ would not be in keeping with the above referenced FAA design and safety standard. Since W:\PIEDMONT\DEIS\Ch_3\Ch_3.doc\3/24/00 3-29 Section 3.0 Alternatives none of these five alternatives met all of the Level 1 purpose and need screening criteria, they were not retained for further evaluation in this DEIS. Alternatives W2-A through W2-E - Alternative W2-A, which is the sponsor's proposed project, would meet all of the Level 1 purpose and need criteria, therefore, it was retained for further evaluation in the Level 2 analysis. Runway-sorting/distribution facility site Alternatives W2-13 through W2-E would partially meet the purpose and need criteria for the proposed project. All of these alternatives would locate the overnight, express air cargo hub at PTIA, provide redundant 9,000-foot Transport-Category runways, provide the ability to conduct dual simultaneous independent IFR operations and provide the capability to conduct head-to-head operations during times of peak air cargo operations. However, none of these alternatives would provide a sorting/distribution site located between parallel runways, which, as described in the TAAM analysis, is critical to meeting cargo hub operational needs. The location of the sort/distribution facility site associated with Alternative W2-C does not meet FAA Standards and Recommendations for Airport Design (Advisory Circular 150/5300-13) because a large portion of the proposed site (approximately 40 percent) would fall within the future RPZ of proposed parallel Runway 5U23R. FAA's design guidelines, which were developed to enhance the protection of people and property on the ground, prohibit the development of places of public assembly within a RPZ, and further recommends that it is desirable that the RPZ remain clear of all objects. The development of the sorting/distribution facility within the RPZ would not be in keeping with the above referenced FAA design and safety standard. Since none of these four alternatives met all of the Level 1 purpose and need criteria, they were not retained for further evaluation in this DEIS. Alternatives W3-A through W3-E - Runway-sorting/distribution facility site Alternative W3-A would locate the overnight, express air cargo hub at PTIA, provide redundant 9,000-foot Transport-Category runways, provide the ability to conduct dual simultaneous independent IFR operations, provide the capability to conduct head-to-head operations during times of peak air cargo operations, locate the sorting/distribution facility site between the parallel runways to meet operational needs. Since this alternative scenario met all of the Level 1 purpose and need criteria, it was retained for further evaluation in the Level 2 analysis. Alternatives W3-13, W3-C, W3-D, and W3-E did not meet all of the Level 1 criteria because they would not provide a sorting/distribution facility site between the parallel runways, which is critical to meeting operational needs. The location of the sort/distribution facility site associated with Alternative W3-C does not meet FAA Standards and Recommendations for Airport Design (Advisory Circular 150/5300-13) because a large portion of the proposed site (approximately 50 percent) would fall within the future RPZ of proposed parallel Runway 5U23R. FAA's design guidelines, which were developed to enhance the protection of people and property on the ground, prohibit the development of places of public assembly within a RPZ, and further recommends that it is desirable that the RPZ remain clear of all objects. The development of the sorting/distribution facility within the RPZ would not be in keeping with the above referenced FAA design and safety standard. Since none of these four alternatives met all of the Level 1 purpose and need criteria, they were not retained for further evaluation in this DEIS. Alternatives E1-A through E1-E - Runway-sorting/distribution facility site Alternatives Ell -A through El -E would only partially meet the purpose and need criteria for the proposed project. All of these alternatives would locate the overnight, express air cargo hub at PTIA, provide redundant 9,000-foot Transport- W:\PIEDMONl1DEIS\Ch_3\Ch_3.doc\3/24/00 3-30 Section 3.0 Alternatives Category runways, provide the ability to conduct dual simultaneous independent IFR operations and provide the capability to conduct head-to-head operations during times of peak air cargo operations. However, Alternatives E1-A, E1-C, and El -D did not meet the Level 1 criteria because they did not provide a sorting/distribution facility site between the parallel runways. Alternative El -13 and El -E did not meet the Level 1 purpose and need criteria because with the 3,400 foot runway centerline separation, they did not provide a sorting/distribution facility site of sufficient size to meet the air cargo carrier's operational requirements. In addition, the location of the proposed parallel runway in all of the E1 alternatives would require the relocation of existing railroad infrastructure, which would take a minimum of 5 to 7 years to accomplish because of the required coordination with other agencies (Surface Transportation Board), and because new construction could not occur until the railroad was relocated. Since none of these five alternatives met all of the Level 1 purpose and need criteria, they were not retained for further evaluation in this DEIS. Alternatives E2-A through E2-E - Runway-sorting/distribution facility site Alternatives E2-A through E2- E would only partially meet the purpose and need criteria for the proposed project. All of these alternatives would locate the overnight, express air cargo hub at PTIA, provide redundant 9,000-foot Transport- Category runways, provide the ability to conduct dual simultaneous independent FIR operations and provide the capability to conduct head-to-head operations during times of peak air cargo operations. However, Alternatives E2-A, E2-C, and E2-D did not meet the Level 1 criteria because they did not provide a sorting/distribution facility site between the parallel runways. Alternatives E2-13 and E2-E did not meet the Level 1 purpose and need criteria because with the 4,300 foot runway separation, these alternatives would not provide a sorting/distribution site of sufficient size to meet the air cargo carrier's operational requirements. All of the "E2" parallel runway alternatives would require the relocation of existing railroad infrastructure, which, as discussed for the E1 Alternatives, would take a minimum of 5 to 7 years to accomplish. Since none of these five alternatives met all of the Level 1 purpose and need criteria, they were not retained for further evaluation in this DEIS. Alternatives N-A through WE - Alternatives N-D and WE met all of the Level 1 purpose and need criteria; therefore, these alternatives were retained for further evaluation in the Level 2 analysis. Alternatives N-A and N-C did not meet the Level 1 criteria because they did not provide a sorting/distribution facility site between the parallel runways, which is critical to meeting the cargo hub's operational needs. Alternative N-B did not meet the Level 1 purpose and need criteria because it did not provide a sorting/distribution facility site of sufficient size to meet the air cargo hub's operational requirements. Since none of these three alternatives met all of the Level 1 purpose and need criteria, they were not retained for further evaluation in this DEIS. Alternatives S-A through S-E - Alternatives S-A, S-B, S-D, and S-E did not meet the Level 1 criteria because they did not provide a sorting/distribution facility site between the parallel runways. Alternative S- C did not meet the Level 1 purpose and need criteria because it did not provide a sorting/distribution facility site of sufficient size to meet the air cargo hub's operational requirements. All of the "S" parallel runway alternatives would require the relocation of existing railroad infrastructure, which, as discussed for the E1 and E2 Alternatives, would take a minimum of 5 to 7 years to accomplish. Since none of these five \\cInt01\wp_wpro\PIEDMONT\DEIS\Ch_3\Ch_3.doc\3/23/00 3-31 Section 3.0 Alternatives alternatives met all of the Level 1 purpose and need criteria, they were not retained for further evaluation in this DEIS. Citizens Scoping Alternative - Review of the citizens Scoping alternative (Figure 3.3.2-2) indicates that it would only partially meet the Level 1 purpose and need criteria for the proposed project at PTIA. This alternative would locate the air cargo facility at PTIA, provide redundant 9,000-foot Transport-Category runways, and provide a site of approximately 300 acres for the development of the air cargo sorting/distribution facility. However, this alternative would not provide the ability to conduct dual simultaneous independent IFR operations, it would not provide the ability to conduct head-to-head operations during times of peak air cargo operations and it would not provide a sorting/distribution facility site located between parallel runways. In terms of the proposed runway improvements associated with this alternative, the proposed 700 to 1,000 foot relocation of the existing Runway 5 threshold does not meet FAA Standards and Recommendations for Airport Design (Advisory Circular 150/5300-13) because it would not provide sufficient distance between the relocated end of Runway 5 and existing Runway 14/32 to provide a standard RSA, jet-blast protection, or sufficient TERPS clearance for Runway 14/32. The use of perpendicular runways under the citizens alternative would result in operational conditions that would lessen the overall efficiency of aircraft operations such as dependent operations (operations on one runway would affect/limit operations on the other runway) and increased runway crossings, change local and potentially regional flight patterns (more daytime and nighttime air carrier and air cargo operations on Runway 14/32 in an east-west orientation as opposed to north-south orientation under existing operational conditions on Runway 5/23) and result in potential safety concerns such as increased use of a designated crosswind runway and increased runway crossings at PTIA. The location of the proposed sorting/distribution facility site associated with this alternative also does not meet FAA Standards and Recommendations for Airport Design (Advisory Circular 150/5300-13) because a large portion of the proposed site (approximately 90 percent) would fall within the future RPZ of proposed 10,000 foot parallel Runway 5U23R, as depicted on PTIA's current ALP. The FAA's aforementioned design guidelines, which were developed to enhance the protection of people and property on the ground, prohibit the development of places of public assembly within a RPZ, and further recommend that it is desirable that the RPZ remain clear of all objects. The development of the sorting/distribution facility within the RPZ would therefore not be consistent with the above referenced FAA safety and design standards. The development of the sorting/distribution facility in the location and configuration proposed in the citizens alternative scenario, based on PTIA's current ALP, would also result in constraints that would preclude the full development of the proposed air cargo sorting/distribution facility because it would not provide an adequate balance of airfield, surface transportation access, and operational staging space. To address these issues, the citizens alternative further proposes that the future 10,000 foot parallel runway depicted on the PTIA ALP be shortened to a length of 7,000. This would relocate the future Runway 5L RPZ to the north, such that it would not conflict with the citizen's proposed location of the air cargo sort/distribution facility. However, the 7,000 foot parallel runway proposed by the citizens is not consistent with PTIA's ALP, and it would preclude development of a parallel runway of sufficient length and utility to meet the operational requirements of the air cargo hub. \\cln10l\wp_wpro\PIEDMOMIDEIS\Ch_3\Ch_3.doc\3/23/00 3-32 Section 3.0 Alternatives As calculated by the citizens submitting this alternative for FAA consideration, impacts associated with the sorting/distribution facility portion of this alternative would include the acquisition and relocation of approximately 26 commercial and 63 residential properties, the relocation of the airport fire station, the closure of a portion of Regional Road, from the intersection Bryan Boulevard to the intersection of US Highway 421, and the isolation (taking) of an existing 1.4-acre cemetery. FAA's analysis of this alternative indicates that because the sorting/distribution facility site geometry must be contiguous (as stated by the sponsor), this alternative would require the relocation of the airport fire station, a City of Greensboro fire station, the primary BellSouth (fiber optic) switching station and the taking of an existing 1.4-acre cemetery, which would result in an impact to a historic resource. Roadway infrastructure impacts would include the closure of a portion of Regional Road, from the intersection Bryan Boulevard to the intersection of US Highway 421. FAA gave full consideration to the citizen's alternative using the same Level 1 criteria as was used to evaluate all of the other on and off-site alternatives. FAA's evaluation concluded that this alternative did not meet all of the Level 1 purpose and need criteria, therefore it was not retained for further consideration in this DEIS. Alternative W1-A1 - In August 1999, the PTAA requested that the FAA consider in the DEIS an additional "west" runway alternative that was developed by the PTAA as a result of detailed planning efforts associated with the ongoing PTIA Master Plan Update. This alternative, designated as Alternative W1-A1, is similar to Alternative W II-A. However, under this alternative, the centerline separation distance between the proposed new parallel runway and existing Runway 5/23 would be 5,088 feet, as compared to Alternative W1-A, in which it would be 4,300 feet. This increased runway centerline separation distance provides a sorting/distribution facility site of sufficient size, located between the parallel runways, to meet the operational needs of the air cargo carrier. Under this alternative, the threshold of the end of new Runway 23R would be shifted approximately 1,032 feet to the southwest, the same as in Runway Alternative W3. The increased separation distance between the parallel runways associated with Alternative W1-A1 would result in a need to relocate a 2-mile segment of Bryan Boulevard to the west of its current location. A new interchange for Bryan Boulevard and Old Oak Ridge Road would also need to be developed. Review of Alternative W1-A1 indicates that it would meet all of the Level 1 purpose and need criteria in that it would locate the overnight, express air cargo facility at PTIA, provide redundant 9,000-foot Transport-Category runways; provide the ability to conduct dual simultaneous independent IFR operations and the capability to conduct head-to-head operations during times of peak air cargo operations, and it would provide for a sorting/distribution facility site of sufficient size, located between the parallel runways, to meet the air cargo hub's operational needs. Since Alternative W1-A1 met all of the Level 1 purpose and need criteria, it was retained for further evaluation in the Level 2 analysis. Level 1 Screening Summary - As a result of the methodical assessment and analysis of each of the 42 runway-sort/distribution facility alternatives in the Level 1 screening process, five build alternatives (W2-A, W3-A, N-D, WE and W1-A1) met all of the Level 1 purpose and need criteria (see Table 3.3.3-1). These W:\PIEDMONT\DEIS\Ch_3\Ch_3.doc\3/24/00 3-33 Section 3.0 Alternatives five alternatives were retained for further evaluation in the Level 2 screening process. All other PTIA runway-sort/distribution facility alternatives did not meet one or more of the Level 1 purpose and need screening criteria and were, therefore, not retained for further evaluation. 3.3.3.3 Level 2 Screening The five runway-sort/distribution facility alternatives retained through the Level 1 analysis (W2-A, W3-A, N- D, N-E and W1-Al) as well as the No-Action Alternative were carried forward to the Level 2 screening process, which evaluated the alternatives in terms of constructability issues, cost considerations and environmental impacts. Constructability issues included impacts to existing or planned infrastructure, the number of residences and businesses that would have to be relocated to construct each alternative, and the amount of property acquisition required. Cost considerations included the estimated total cost for those development items eligible for FAA reimbursement (including mitigation costs). Environmental impacts included direct and indirect impacts to specific environmental categories listed in FAA Order 5050.4A (the complete investigation and discussion of the affected environment and impact analysis appears in Chapters 4 and 5). The following presents the results of the Level 2 analysis. No-Action Alternative - The No-Action Alternative infers the overnight, express air cargo sorting and distribution facility (FedEx Mid-Atlantic Hub) would not be developed at PTIA. This alternative would involve no new construction of airside facilities or landside facilities associated with the air cargo facility, and no other PTIA airside and landside developments beyond those that are already programmed or undertaken by the PTAA for safety and maintenance reasons. The PTAA plans several surface transportation improvement projects that would be initiated whether or not the air cargo facility were to locate at PTIA. These projects would be funded by the FHWA and NCDOT. Infrastructure impacts from development of the surface transportation projects associated with the No-Action Alternative include closure and relocation of a portion of Regional Road, realignment of a portion of Old Oak Ridge Road, construction of a new interchange for Bryan Boulevard and Old Oak Ridge Road, construction of a new airport entrance interchange for existing North Triad Boulevard and development of a new interchange for South Triad Boulevard. Implementation of the No-Action Alternative would require the relocation of one home and the acquisition of approximately 13.66 acres of property for right-of-way acquisition for the roadway projects. The right-of- way acquisition would include any realigned roadway as well as the cleared/maintained safety areas off the sides of the roadways. The surface transportation improvements would result in adverse impacts to approximately 9.8 acres of wetlands and 23.1 acres located within the 100-year floodplain (see Chapter 5.0, Environmental Consequences). This alternative would not result in direct or indirect impacts to DOT Section 303(c) resources or direct impacts to Section 106 Historic Resources. Existing indirect impacts to one Section 106 historic architectural site (Campbell-Gray Farm) from aircraft generated noise would be lessened, with DNL levels decreasing from DNL 70.5 dBA in 1998 to DNL 68.6 dBA in Phase 1 and DNL 69.2 dBA in Phase 2. Based on FAA noise compatibility guidelines, noise levels from aircraft operations would be above FAA's threshold of compatibility (which is DNL 65 dBA) at this site with the No-Action Alternative. The total cost for the No-Action Alternative is estimated to be approximately $25.7million, including construction, acquisition and relocation and wetlands mitigation. \\clnt01\wp_wpro\PIEDMONT\DEIS\Ch_3\Ch_3.doc\3/23/00 3-34 Section 3.0 Alternatives Alternative W2-A - Surface transportation impacts from development of the parallel runway associated with Alternative W2-A include partial closure of Lebanon Road west of Drum Road, Brush Road north of Canoe Road, and a small portion of North Regional Road west of Bryan Boulevard. Partial closure of Caindale Drive east of the Airport Surveillance Radar (ASR) would also be required. Infrastructure impacts from the development of the air cargo sorting/distribution facility site associated with Alternative W2-A, north of the existing airport terminal, include closure of Air Cargo Road and partial closures of North Service Road and Inman Road south, of the Bryan Boulevard/Inman Road intersection. PTAA has the option of either purchasing lands within the RPZ's or obtaining avigation easements over the individual properties. If PTAA purchases all property within the proposed parallel runway RPZ's, relocation impacts north of the airport would include six residential properties on Phillipsburg Court, and one residential property on Old Oak Ridge Road. RPZ acquisition-related off-airport relocation impacts southwest of the airport include two residential properties on Canoe Road east of Burgess Road, and nine industrial properties along Burgess Road north of Market Street. Relocation impacts from development of the air cargo sorting/distribution facility site associated with Alternative W2-A, north of the airport would include one commercial property along Inman Road. On-airport relocation impacts include all rental car turnaround, servicing, and parking facilities (six buildings), a parking lot, Dobbs kitchen, and air cargo facilities (two multi-tenant sort/distribution buildings). Implementation of Alternative W2-A would require the acquisition of approximately 88.37 acres of property, primarily to enable the PTAA to own the RPZs for proposed parallel Runway 5L/23R. The total cost for Alternative W2-A, including property acquisition and relocation, construction of the parallel runway, taxiways and associated NAVAIDS, air cargo sorting/distribution facility site preparation, and mitigation for wetland impacts would be approximately $221.3 million. A complete discussion of environmental impacts associated with this alternative is contained in Chapter 5.0, Environmental Consequences. In summary, direct environmental impacts associated with construction of Alternative W2-A include the relocation of nine homes (approximately 21 people) and nine industrial facilities, and adverse impacts to approximately 32.3 acres of wetlands and 36.6 acres located within the 100-year floodplain (see Chapter 5.0, Environmental Consequences). This alternative would not result in direct or indirect impacts to DOT Section 303(c) resources or direct impacts to Section 106 Historic Resources. Aircraft generated indirect noise impacts to one Section 106 historic architectural site (Campbell-Gray Farm) would decrease when compared to the 1998 existing condition, with DNL levels decreasing from DNL 70.5 dBA in 1998 to DNL 70.2 dBA in Phase 1. Compared to the No-Action Alternative, DNL levels would increase slightly from DNL 68.6 dBA to DNL 70.2 dBA in Phase 1 and from DNL 69.2 dBA to DNL 71.0 dBA in Phase 2. Based on FAA noise compatibility guidelines, noise levels from aircraft operations would be above FAA's threshold of compatibility (which is DNL 65 dBA) at this site with Alternative W2-A. Alternative W3-A - Surface transportation impacts from the development of the parallel runway associated with Alternative W3-A include partial closure of Lebanon Road west of Drum Road, Brush Road north of Canoe Road, and a small portion of North Regional Road west of Bryan Boulevard. The \\c1nt01\wp_wpro\PIEDMONT\DEIS\Ch_3\Ch_3.doc\3/23/00 3-35 Section 3.0 Alternatives partial closure of Caindale Drive east of the ASR would also be required. Surface transportation impacts from the development of the sorting/distribution facility site associated with Alternative W3-A, north of the existing airport terminal include closure of Air Cargo Road and partial closures of North Service Road and Inman Road, south of the Bryan Boulevard/Inman Road intersection. PTAA has the option of either purchasing lands within the RPZ's or obtaining avigation easements over the individual properties. If PTAA purchases all properties within the RPZs, relocation impacts from the development of the parallel runway portion of Alternative W3-A would include two residential properties at the corner of Brush Road and Lebanon Road, two residential properties on Canoe Road east of Burgess Road, one residential property along Old Oak Ridge Road, and 13 industrial properties along Burgess Road north of Market Street. Off-airport relocation impacts from development of the sorting/distribution facility site associated with Alternative W3-A, north of the airport, include one commercial property along Inman Road. On-airport relocation impacts would include all rental car turnaround, servicing, and parking facilities (six buildings), a parking lot, Dobbs kitchen, and air cargo facilities (two multi-tenant sort/distribution buildings). Construction of Alternative W3-A would require the acquisition of approximately 89.89 acres of property, primarily to enable the PTAA to own the RPZs for proposed parallel Runway 5U23R. The total cost for Alternative W3-A, including the parallel runway, taxiway and associated NAVAIDS, hub site preparation, acquisitions and relocations, and wetland mitigation would be approximately $226.6 million. A complete discussion of environmental impacts associated with this alternative is contained in Chapter 5.0, Environmental Consequences. In summary, direct environmental impacts associated with construction of Alternative W3-A include relocation of five homes (approximately 12 people), 14 industrial and commercial properties, and adverse impacts to approximately 29.8 acres of wetlands and 34.6 acres located within the 100-year floodplain (see Chapter 5.0, Environmental Consequences). This alternative would not result in direct or indirect impacts to Section 303(c) resources or direct impacts to Section 106 Historic Resources. Aircraft generated indirect noise impacts to one Section 106 historic architectural site (Campbell-Gray Farm) would decrease when compared to the 1998 existing condition, with DNL levels decreasing from DNL 70.5 dBA in 1998 to DNL 70.2 dBA in Phase 1. Compared to the No-Action Alternative, DNL levels would increase slightly from DNL 68.6 dBA to DNL 70.2 dBA in Phase 1 and from DNL 69.2 dBA to DNL 71.0 dBA in Phase 2. Based on FAA noise compatibility guidelines, noise levels from aircraft operations would be above FAA's threshold of compatibility (which is DNL 65 dBA) at this site with Alternative W3-A. Alternative N-D - Surface transportation impacts to the west of the airport from the development of the extension of existing Runway 14/32 would consist of the partial closure of Lebanon Road, west of Brush Road. Surface transportation impacts to the west of the airport from the development of new Runway 14U32R would consist of the closure of Hollandsworth Drive, Hollandsworth Court and Calico Drive. Impacts to on-airport roads would include closure of Air Cargo Road north of Bryan Boulevard and North Service Road, and the realignment of North Triad Boulevard. Impacts to local roadways at the east end of the new Runway 14U32R and parallel taxiway include partial closure of Stage Coach Trail north of Holly Crest Court, partial closure of Ballinger Road west of Breezewood Road, and the full closure of Wagon \\clnt01\wp_wpro\PIEDMONTDEIS\Ch_3\Ch_3.doc\3/23/00 3-36 Section 3.0 Alternatives Wheel Drive, Carriage Lane, and Coach Hill Road. Infrastructure impacts from development of the air cargo sorting/distribution facility site associated with Alternative N-D, west of the airport, include closure of Bentley Road, Business Park Drive, and Skyway Drive, and the partial closure of the easternmost portion of Caindale Drive. PTAA has the option of either purchasing lands within the RPZ's or obtaining avigation easements over the individual properties. If PTAA purchases all lands required for the sorting/distribution facility site and the RPZ's, off-airport relocation impacts west of the airport associated with the runway portion of Alternative N-D would include two residential properties along Caindale Drive, four residential properties along Hollandsworth Drive, two residential properties along Hollandsworth Court, and four residential properties along Calico Drive. The Airport Surveillance Radar (ASR) located on Caindale Drive would also require relocation. Off-airport relocation impacts east of the airport from the parallel runway include four residential properties along Stage Coach Trail, 10 residential properties along Breezewood Road, 10 residential properties along Wagon Wheel Drive, 15 residential properties along Carriage Lane, 12 residential properties along Coach Hill Road, and one residential property along Ballinger Road. Off-airport relocation impacts associated with the development the sorting/distribution facility site associated with Alternative N-D, west of the airport, include Friendship Baptist Church and cemetery, 12 residential, and two commercial properties along Bentley Road, two industrial properties along Caindale Drive, and eight industrial properties along Business Park Drive. Relocation impacts to on-airport commercially leased parcels from the parallel runway include the relocation of all rental car turnaround, servicing and parking facilities (six buildings), a parking lot, Dobbs kitchen, fuel farm, and air cargo (two multi-tenant sort/distributions building). In addition, the implementation of the cumulative surface transportation projects would require the relocation of one residential property on Old Oak Ridge Road. Construction of Alternative N-D would require the acquisition of approximately 315.01 acres of property, primarily for sufficient land area to develop the sorting/distribution facility site and to enable the PTAA to own the RPZs for proposed parallel Runway 14U32R. The total cost for Alternative N-D, including the parallel runway, extension of Runway 14/32, taxiways, NAVAIDS, air cargo site preparation, property acquisition and relocation, and wetland mitigation would be approximately $328.5 million. A complete discussion of environmental impacts associated with this alternative is contained in Chapter 5.0, Environmental Consequences. In summary, direct environmental impacts associated with construction of Alternative N-D include relocation of 77 homes (approximately 182 people), two commercial facilities, and 10 industrial properties and adverse impacts to approximately 36.8 acres of wetlands and 49.6 acres located within the 100-year floodplain (see Chapter 5.0, Environmental Consequences). This alternative would result in indirect impacts from aircraft generated operational noise to 10 Section 303(c) resources and indirect impacts from aircraft generated operational noise to three Section 106 historic architectural properties (Guilford College Historic District, Roy Edgerton House and New Garden Friends Cemetery). Alternative WE - Surface transportation impacts to the west of the airport from the development of the extension of existing Runway 14/32 would consist of the partial closure of Lebanon Road, west of Brush Road. Surface transportation impacts to the west of the airport from the development of new Runway W:\PIEDMONT\DEIS\Ch_3\Ch_3.doc\3/24/00 3-37 Section 3.0 Alternatives 14U32R would consist of the closure of Hollandsworth Drive, Hollandsworth Court and Calico Drive. Impacts to local roadways at the east end of the new Runway 14U32R and parallel taxiway include the closure of Stage Coach Trail north of Holly Crest Court, partial closure of Ballinger Road, west of Breezewood Road, and the closure of Wagon Wheel Drive, Carriage Lane, and Coach Hill Road. Surface transportation impacts from development of the air cargo sorting/distribution facility site associated with Alternative N-E, east of the airport, would consist of partial closure of Radar Road. On-airport roadway impacts would include closure of Air Cargo Road north of Bryan Boulevard and North Service Road, and the realignment of North Triad Boulevard. PTAA has the option of either purchasing lands within the RPZ's or obtaining avigation easements over the individual properties. If PTAA purchases all lands required for the RPZ's, off-airport relocation impacts west of the airport associated with the new runway portion of Alternative N-E would include two residential properties along Caindale Drive, four residential properties along Hollandsworth Drive, two residential properties along Hollandsworth Court, and four residential properties along Calico Drive. Off-airport relocation impacts east of the airport from the new parallel runway would include four residential properties along Stage Coach Trail, 10 residential properties along Breezewood Road, 10 residential properties along Wagon Wheel Drive, 15 residential properties along Carriage Lane, 12 residential properties along Coach Hill Road, and one residential property along Ballinger Road. Off-airport relocation impacts from development the sorting/distribution facility site associated with Alternative N-E, east of the airport, include seven industrial buildings (plus approximately five support buildings) along Radar Road. On-airport relocations would consist of commercially leased parcels including the rental car turnaround, servicing and parking facilities (six buildings), a parking lot, Dobbs kitchen, fuel farm, air cargo (two multi- tenant sort/distributions building) and six commercially leased large maintenance hangars (with six support buildings) along Radar Road. In addition, the implementation of the cumulative surface transportation projects would require the relocation of one residential property on Old Oak Ridge Road. Construction of Alternative N-E would require the acquisition of approximately 266.14 acres of property, primarily for sufficient land area to develop the sorting/distribution facility site and to enable the PTAA to own the RPZs for proposed parallel Runway 14U32R. The total cost for Alternative N-E, including the parallel runway, extension of Runway 14/32, taxiways, NAVAIDS, air cargo site preparation, property acquisition and relocation, and wetland mitigation would be approximately $414.6 million. A complete discussion of environmental impacts associated with this alternative is contained in Chapter 5.0, Environmental Consequences. In summary, direct environmental impacts associated with construction of Alternative N-E include relocation of 65 homes (approximately 154 people), 13 commercial / industrial facilities (plus associated support buildings) and adverse impacts to approximately 31.3 acres of wetlands and 46.4 acres located within the 100-year floodplain (see Chapter 5.0, Environmental Consequences). This alternative would result in indirect impacts from aircraft generated operational noise to 10 Section 303(c) resources and indirect impacts from aircraft generated operational noise to two Section 106 historic architectural properties (New Garden Friends Cemetery and Shaw-Cude House). \\clM01\wp_wpro\PIEDMONrDEIS\Ch_3\Ch_3.doc\3/23/00 3-38 Section 3.0 Alternatives Alternative W1-Ai - Surface transportation impacts from development of the parallel runway associated with Alternative W1-A1 would include the relocation of a 2 mile segment of Bryan Boulevard (and demolition of the existing alignment), and partial closure of Lebanon Road west of Drum Road, Brush Road north of Canoe Road, and a small portion of North Regional Road west of Bryan Boulevard. Partial closure of Caindale Drive east of the Airport Surveillance Radar (ASR) would also be required. Surface transportation impacts from the development of the sorting/distribution facility site associated with Alternative W1-A1, north of the existing airport terminal, would include closure of Air Cargo Road and partial closures of North Service Road and Inman Road south of the Bryan Boulevard/Inman Road intersection. PTAA has the option of either purchasing lands within the RPZ's or obtaining avigation easements over the individual properties. If PTAA purchases all properties within the RPZs, relocation impacts from the development of the parallel runway portion of Alternative W1-Al would include six residential properties along Brush Road north of Canoe Road, two residential properties along Drum Road south of Lebanon Road, three residential properties on Canoe Road east of Burgess Road, 17 industrial properties and one commercial property along Burgess Road north of Market Street, and two commercial properties along Canoe Road west of Brush Drive. Off-airport relocation impacts from development of the sorting/distribution facility site associated with Alternative W1-Al, north of the airport would include one commercial property along Inman Road. On-airport relocation impacts include all rental car turnaround, servicing, and parking facilities (six buildings), a parking lot, Dobbs kitchen, and air cargo facilities (two multi-tenant sort/distribution buildings). Relocation impacts from the realignment of Bryan Boulevard and the new Bryan Boulevard/Old Oak Ridge Road interchange include 35 residential properties in the College Lakes development, located south of Old Oak Ridge Road and east of Pepperdine Road and one residential property along Old Oak Ridge Road. Implementation of Alternative W1-A1 would require the acquisition of approximately 154.74 acres of property, primarily to enable the PTAA to own the RPZs for proposed parallel Runway 5L/23R. The total cost for Alternative W1-A1, including property acquisition, and relocation construction of the parallel runway, taxiways and associated NAVAIDS, sorting/distribution facility site preparation, and mitigation for wetland impacts would be approximately $227.3 million. A complete discussion of environmental impacts associated with this alternative is contained in Chapter 5.0, Environmental Consequences. In summary, direct environmental impacts associated with construction of Alternative W1-A1 include the relocation of 47 homes (approximately 111 people), 17 industrial, and four commercial facilities and adverse impacts to approximately 27.3 acres of wetlands and 25.4 acres located within the 100-year floodplain (see Chapter 5.0, Environmental Consequences). This alternative would not result in direct or indirect impacts to DOT Section 303(c) resources or direct impacts to Section 106 Historic Resources. Aircraft generated indirect noise impacts to one Section 106 historic architectural site (Campbell-Gray Farm) would decrease when compared to the 1998 existing condition, with DNL levels decreasing from DNL 70.5 dBA in 1998 to DNL 70.2 dBA in Phase 1. Compared to the No-Action Alternative, DNL levels would increase slightly from DNL 68.6 dBA to DNL 70.2 dBA in Phase 1 and from DNL 69.2 dBA to DNL 71.0 dBA in Phase 2. Based on FAA noise compatibility guidelines, noise \\clnt01\wp_wpro\PIEDMONnDEIS\Ch_3\Ch_3.doc\3/23/00 3-39 Section 3.0 Alternatives levels from aircraft operations would be above FAA's threshold of compatibility (which is DNL 65 dBA) at this site with Alternative W 1-Ai . Level: 2 Screening Summary - As a result of the systematic assessment and analysis of each of the remaining six alternatives in the Level 2 screening process, all of the six alternatives (No-Action, W2-A, MA N-D, WE and W1-A1) were retained for detailed evaluation in Chapter 5.0, Environmental Consequences, of this DEIS. 3.3.4 ALTERNATIVES CONSIDERED AND NOT RETAINED FOR DETAILED ANALYSIS In this chapter of this DEIS, numerous alternatives that had some reasonable potential to meet the purpose and need for the proposed project were examined. However, most of these alternatives were not considered to adequately fulfill the criteria of the two-level alternatives analysis process and were therefore not considered to be reasonable alternatives. Alternatives that were not retained for further detailed study in this DEIS include the following: • The development of a new airport ("Greenfield Site"); • The use/expansion of other existing airports, and • A total of 37 runway/sorting/distribution facility site alternatives including X-A through X-E, W1-A through W1-E, W2-13 through W2-E, W3-13 through W3-E, E1-A through E1-E, E2-A through E2-E, N-A through N-C, S-A through S-E, and the alternative submitted by citizens during the DEIS Scoping process. 3.3.5 ALTERNATIVES CONSIDERED AND RETAINED FOR DETAILED ANALYSIS Alternatives that were retained for detailed study in this DEIS include the following: • No-Action Alternative, • Alternative W2-A (PTAA's proposed project), • Alternative MA • Alternative N-D, • Alternative N-E, and • Alternative W1-A1. The alternatives that were retained for detailed study at this point in the DEIS, prior to rigorous scrutiny, appear to be reasonable alternatives towards meeting the purpose and need for the proposed project. The No-Action Alternative has also been retained for detailed analysis in subsequent chapters of this DEIS for baseline comparative purposes and to disclose impacts without the proposed project. \\clnt01\wp_wpro\PIEDMONT\DEIS\Ch_3\Ch_3.doc\3/23/00 3-40 Section 3.0 Alternatives 3.4 DESCRIPTION OF ALTERNATIVES RETAINED FOR DETAILED ANALYSIS This section of the DEIS provides a detailed description of the runway/sorting/distribution facility site alternatives that remained after passing through the two-level alternatives screening process. On the basis of being able to meet all of the Level 1 purpose and need criteria, and the Level 2 constructability, cost and environmental impact considerations, five build alternative concepts: Alternative W2-A, Alternative W3-A, Alternative N-D, Alternative WE and Alternative W1-A1 were retained as reasonable alternatives. All five build alternative scenarios provide for a similar magnitude of development and provide the capability to conduct dual simultaneous independent IFR operations. The No-Action Alternative and the five build alternatives are depicted on Figures 3.4-1 through 3.4-6. 3.4.1 No-ACTION ALTERNAT/vE The No-Action Alternative (Figure 3.4-1), assumes that the overnight, express air cargo hub would not be developed at PTIA. This alternative would involve no new construction of airside facilities or landside facilities associated with the air cargo hub, and no other PTIA airside and landside developments beyond those that are already programmed or undertaken by the PTAA for safety and maintenance reasons. The PTAA plans to initiate several roadway improvement projects that would be developed whether or not the air cargo hub were to locate at PTIA. Implementation of these projects would require PTAA to purchase approximately 13.66 acres of property. These projects include the following: • Construction of a new interchange for Bryan Boulevard and Old Oak Ridge Road, • Realignment of a portion of Old Oak Ridge Road, • Closure and relocation of a portion of Regional Road, and • Construction of new airport entrance interchange for North Triad Boulevard and reconstruction of the South Triad Boulevard interchange. The above listed projects are independent actions which may produce cumulative impacts when considered with the build alternatives. These actions would be initiated by the PTAA within the timeframe of the proposed project evaluated within this DEIS. The potential cumulative environmental impacts associated with them are disclosed in Chapter 5.0, Environmental Consequences, of this DEIS. The total cost of the proposed improvement identified as part of the No-Action Alternative would be approximately $25.7 million. 3.4.2 ALTERNATIVE W2-A Alternative W2-A (Figure 3.4-2), is the development alternative depicted on PTAA's current ALP and is the PTAA's proposed project. Phase 1 projects evaluated within this DEIS consist of the following developments, which the sponsor anticipates would need to be constructed and operational by the year 2004. \\clnt0l\wp_wpro\PIEDMONnDEIS\Ch_3\Ch_3.doc\3/23/00 3-41 Section 3.0 Alternatives • Construction of a new parallel 9,000-foot by 150-foot Transport-Category runway capable of accommodating Airplane Design Group D-V air carrier aircraft (DC-10). The airfield system complex consists of the runway and taxiway as described; parallel and connecting taxiways; lighting; CAT II/III NAVAIDS; runway safety areas and protection zones, and associated grading, drainage, and utility relocations; • Cross-field extension of Taxiway D; • Construction of a high speed exit taxiway for Runway 5/23; • Construction and operation of Phase 1 of the air cargo sorting/distribution hub facility (approximately 736,000 square feet including sort/distribution building and parking); • Construction and operation of Phase 1 of the air cargo aircraft parking and cargo ramp (approximately 174,000 square yards); • Construction of a tunnel for Bryan Boulevard under the proposed parallel runway; • Construction of one connector taxiway bridge over Bryan Boulevard; • Relocation of on-airport rental car service lots; • Relocation of two existing air cargo buildings; • Implementation of air traffic procedures below 3,000 feet above ground level (AGL); • Acquisition of approximately 88.37 acres of land; and • Obtain State Water Quality Certification Section 401 and USACE Section 404 Wetland fill permits prior to start of construction and implementation of mitigation measures. Phase 2 projects are also illustrated in Figure 3.4-2. It is anticipated by the sponsor that this phase of the project would need to be constructed between the years 2005 and 2009 and be fully operational in the year 2009. These projects, which are environmentally reviewed in this DEIS, include: • Construction and operation of Phase 2 of the air cargo sorting/distribution facility (expand the Phase 1 facility by approximately 509,000 square feet), • Construction and operation of Phase 2 of the air cargo aircraft parking and cargo ramp (expand the Phase 1 parking/ramp area by approximately 281,000 square yards), • Extension of the north cross-field connector taxiways to the Phase 2 apron area, and • Construction of a second connector taxiway bridge and cross-field taxiway over Bryan Boulevard. 3.4.3 ALTERNATIVE W3-A Alternative W3-A (Figure 3.4-3), is similar to Alternative W2-A. The difference between the two is the location of the ends of the proposed parallel runway. The centerline-to-centerline separation between existing Runway 5R/23L and proposed parallel Runway 5U23R remains the same as in Alternative W2-A (5,488 feet). In Alternative W3-A, the end of proposed parallel Runway 5R/23L would be shifted 1,032 feet W:\PIEDMONTDEIS\Ch_3\Ch_3.doc\3/24/00 3-42 Section 3.0 Alternatives to the southwest. This would reduce impacts to Brush Creek wetlands and floodplains and also move the proposed parallel Runway 23L RPZ so that it would not encompass a portion of a residential community (Phillipsburg Court) located north of the proposed parallel runway. Alternative W3-A Phase 1 projects evaluated within this DEIS consist of the following developments, which would be anticipated for construction and operation by the year 2004. • Construction of a new parallel 9,000-foot by 150-foot Transport-Category runway capable of accommodating Airplane Design Group D-V air carrier aircraft (DC-10). The airfield system complex consists of the runway and taxiway as described; parallel and connecting taxiways; lighting; CAT II/III NAVAIDS; runway safety areas and protection zones, and associated grading, drainage, and utility relocations; • Cross-field extension of Taxiway D; • Construction of a high speed exit taxiway for Runway 5/23; • Construction and operation of Phase 1 of the sorting/distribution facility (including approximately 736,000 square feet of sort/distribution building and parking); • Construction and operation of Phase 1 of the air cargo aircraft parking and cargo ramp (approximately 174,000 square yards); • Construction of a tunnel for Bryan Boulevard under the proposed parallel runway; • Construction of one connector taxiway bridge over Bryan Boulevard; • Relocation of on-airport rental car service lots; • Relocation of two existing air cargo buildings; • Implementation of air traffic procedures below 3,000 feet above ground level (AGL); • Acquisition of approximately 89.89 acres of land; and • Obtain State Water Quality Certification Section 401 and USACE Section 404 Wetland fill permits prior to start of construction and implementation of mitigation measures. Phase 2 projects are also illustrated in Figure 3.4-3. It is anticipated by the sponsor that this phase of the project would be constructed between the years 2005 and 2009 and be fully operational in the year 2009. These projects, which are environmentally reviewed in this DEIS, include: • Construction and operation of Phase 2 of the air cargo sorting/distribution facility (expand the Phase 1 facility by approximately 509,000 square feet), • Construction and operation of Phase 2 of the air cargo aircraft parking and cargo ramp (expand the Phase 1 parking/ramp area by approximately 281,000 square yards), • Extension of the north cross-field connector taxiways to the Phase 2 apron area, and • Construction of a second taxiway bridge and cross-field taxiway over Bryan Boulevard. \\c1nt01\wp_wpro\PIEDMONIIDEIS\Ch_3\Ch_3.doc\3/23/00 3-43 Section 3.0 Alternatives 3.4.4 ALTERNATIVE N-D Alternative N-D (Figure 3.4-4), consists of the extension of existing Runway 14/32 by 2,620 feet to the west and the development of a new parallel 9,000-foot Transport-Category runway located approximately 7,630 feet north of existing Runway 14/32. Phase 1 projects evaluated within this DEIS consist of the following developments, which would be anticipated for construction and operation by the year 2004. • Construction of a new parallel 9,000-foot by 150-foot Transport-Category runway in the 14/32 orientation capable of accommodating Airplane Design Group D-V air carrier aircraft (DC-10). The airfield system complex consists of the runway and taxiway as described; parallel and connecting taxiways; lighting; CAT II/III NAVAIDS; runway safety areas and protection zones, and associated grading, drainage, and utility relocations; • Extension of existing Runway 14/32 by 2,620 feet to the west, with the associated reconstruction and extension of Taxiway A; extension of Taxiway C; runway and taxiway lighting; relocation of Runway 14 NAVAIDS, runway safety areas and protection zones, and associated grading, drainage, and utility relocations; • Construction and operation of Phase 1 of the sorting/distribution facility (including approximately 736,000 square feet of sort/distribution building and parking); • Construction and operation of Phase 1 of the air cargo aircraft parking and cargo ramp (approximately 174,000 square yards); • Construction of a tunnel for Bryan Boulevard under the proposed parallel runway; • Construction of two connector taxiway bridges over Bryan Boulevard; • Relocation of on-airport rental car service lots; • Relocation of two existing on-airport air cargo buildings; • Implementation of air traffic procedures below 3,000 feet above ground level (AGL); • Acquisition of approximately 315.01 acres of land; • Relocation of the Airport Surveillance Radar (ASR), and • Obtain State Water Quality Certification Section 401 and USACE Section 404 Wetland fill permits prior to start of construction and implementation of mitigation measures. Phase 2 projects are also illustrated in Figure 3.4-4. It is anticipated by the sponsor that this phase of the project would need to be constructed between the years 2005 and 2009 and be fully operational in the year 2009. These projects, which are environmentally reviewed in this DEIS, include: • Construction and operation of Phase 2 of the air cargo sorting/distribution facility (expand the Phase 1 facility by approximately 509,000 square feet), and • Construction and operation of Phase 2 of the air cargo aircraft parking and cargo ramp (expand the Phase 1 parking/ramp area by approximately 281,000 square yards).

The difference between the two is the separation distance between the existing and proposed runways. The centerline-to-centerline separation between existing Runway 5R/23L and proposed parallel Runway 5L/23R would be 5,088 feet, as compared to 5,488 feet with Alternatives W2-A and W3-A. The Runway 23R threshold would be the same as in Alternative W3-A. That is, shifted 1,032 feet to the southwest when compared to Alternative W2-A. This would reduce impacts to Brush Creek wetlands and floodplains and also move the proposed parallel Runway 23L RPZ so that it would not encompass a portion of a residential community (Phillipsburg Court) located north of the proposed parallel runway. Alternative W1-A1 Phase 1 projects evaluated within this DEIS consist of the following developments, which would be anticipated for construction and operation by the year 2004. • Construction of a new parallel 9,000-foot by 150-foot Transport-Category runway capable of accommodating Airplane Design Group D-V air carrier aircraft (DC-10).

It is anticipated by the sponsor that this phase of the project would need to be constructed between the years 2005 and 2009 and be fully operational in the year 2009. These projects, which are environmentally reviewed in this DEIS, include: • Construction and operation of Phase 2 of the air cargo sorting/distribution facility (expand the Phase 1 facility by approximately 509,000 square feet), and • Construction and operation of Phase 2 of the air cargo aircraft parking and cargo ramp (expand the Phase 1 parking/ramp area by approximately 281,000 square yards). 3.5 PREFERRED ALTERNATIVES The sponsor of the proposed project, the PTAA, has approached FAA with a proposed airport development program (proposed project) for PTIA, which would provide airside and landside improvements needed to accommodate the successful establishment of an overnight, express air cargo facility (FedEx Mid-Atlantic Hub). Alternative W2-A, evaluated within this DEIS, is the proposed project that the PTAA submitted to the FAA for review. However, the PTAA acknowledges that other reasonable alternatives that fulfill the purpose and need for the proposed project may result in less environmental impact. Therefore, the PTAA has determined that it will wait until it has had an opportunity to review the findings of the DEIS before it identifies its preferred alternative. At the Draft stage in the EIS process, the FAA has not identified its preferred alternative(s) for the proposed project. The FAA's selection of a preferred alternative will be included in the Final EIS document, after the agency has had an opportunity to complete full disclosure and analysis of impacts, and interested agency representatives and the public have been afforded an opportunity to review and comment on the DEIS findings. 3.6 LISTING OF FEDERAL LAWS AND REGULATIONS CONSIDERED The following is a list of Federal laws and regulations considered by the agency in the preparation of this DEIS: FEDERAL LAWS AND STATUTES: Subtitle VII Title 49 U.S. Code - "Aviation Programs," (Section 40101, et seq.) recodified from, and formerly known as the "Federal Aviation Act of 1958"' as amended, (P.L. 85-726).

The environmental impacts of the alternatives retained for detailed analyses are presented in Chapter 5.0, Environmental Consequences. For the purposes of describing the existing conditions in the PTIA area and comparing the relative impact of the alternatives (Chapter 5.0), three study areas were developed for this DEIS. For economic impact analysis, a broad Six-County Socioeconomic Study Area was established. For environmental considerations in this DEIS that deal with broad, indirect impact issues, a "Generalized Study Area" was used to describe features and quantify impact potential. The Generalized Study Area includes a large geographic area and was established to quantify impacts that may occur in the surrounding communities, such as impacts to noise-sensitive land use; social and socioeconomic impact; and impacts to Section 303(c), 6(f), and 106 resources. The Generalized Study Area encompasses approximately 80 square miles and includes portions of Guilford County, the City of Greensboro, and the City of High Point. The Generalized Study Area boundaries were established based on the estimated extent of the future Day- Night Average Sound Level (DNL) 65 dB noise contours. A "Detailed Study Area" was similarly established for environmental considerations that deal with more specific, direct impact issues such as wetlands, floodplains, biotic communities, and farmlands. The Detailed Study Area includes the airport property and surrounding property approximately 1 mile off the end of each of the runway alternatives and represents the areas where direct disturbance of area features could potentially occur. The Generalized and Detailed Study Areas are depicted in Figure 4.1-1. 4.2 HUMAN ENVIRONMENT 4.2.1 LAND USE AND LOCAL GOVERNMENTS 4.2.1.1 Geographic Area of Analysis In the beginning of the EIS process, there was concern that the economic and social impacts of the proposed improvements may extend beyond the boundaries of North Carolina and spill over into neighboring Virginia. For this reason, the FAA began its analysis with a broad geographic region and narrowed its focus as the study results indicated. The Technical Memorandum entitled Potential Socioeconomic Impacts of Proposed Improvements to the Piedmont Triad International Airport, included as Appendix E of this EIS, provides a detailed explanation of this process. Based upon this analysis, the geographic region most likely to be impacted by secondary and cumulative impacts includes Alamance, Davidson, Forsyth, Guilford, Randolph, and Rockingham counties and is referred to as the Six-County WAPIEDM0NT\DEIS\Ch_4\S 4.doc 4-1 Chapter 4.0 Affected Environment Socioeconomic Study Area for this EIS. The Six-County Socioeconomic Study Area is shown on Figure 1.2 in Appendix E. The following chapter provides a description of the existing land use, zoning, and local governments in each of the DEIS study areas (Six-County, Generalized, and Detailed). 4.2.1.2 Six-County Socioeconomic Study Area Existing Land Use - PTIA is located in the western portion of Guilford County. Growth in this area is described in a 1996 Strategic Plan sponsored by the Piedmont Triad Partnership: "The Piedmont Triad Region is a triangular 12-county region with the three largest cities (Greensboro, Winston-Salem, and High Point) located in the two central counties of Forsyth and Guilford. As these cities grow, they are merging to form a metropolitan "Triad" in the center of the region" (Michael Gallis & Associates, 1996). PTIA is located in the center of this evolving "Triad." Consequently, since the 1980's, the airport area has been the focus of rapid growth. The Six-County Socioeconomic Study Area includes Alamance, Davidson, Forsyth, Guilford, Randolph, and Rockingham counties. Table 4.2.1-1 describes some land use characteristics of the Six-County Socioeconomic Study Area. The total land area of this six-county area region is 3,397 square miles. Forsyth and Guilford counties with the major cities of Greensboro, Winston-Salem, and High Point form the urbanized core for the six-county region. In 1997, 449,427 residents or 43 percent of the region's population lived in these three major cities. The 1995 population density for the urbanized counties ranged from 572 persons per square mile for Guilford County to 683 persons per square mile for Forsyth County. The population density for the outlying counties has a broader range, from 247 persons per square mile for Davidson County to 268 persons for Alamance County. The more rural counties of Randolph and Rockingham have the lowest population densities of 147 and 156 persons per square mile, respectively. The percent of the 1990 population living in urbanized areas follows a similar pattern as the population density characteristics. Forsyth and Guilford counties have nearly 75 percent and 79 percent, respectively, of their population living within urban areas as compared to only 32 percent for the more rural counties of Davidson, Randolph, and Rockingham counties. Tables 4.2.1-2 and 4.2.1-3 list the 1990 and 1997 city, town, and county population for the Six-County Socioeconomic Study Area. The urbanization of the region is also reflected by the decline in farming, as stated in the agricultural indicators on Table 4.2.1-2. Across the six-county region, the number of farms declined from 7,246 in 1982 to 5,401 in 1992, representing a 25 percent decrease. The total number of farmland acres also dropped from 736,918 acres in 1982 to 630,493 acres in 1992, representing a 17 percent decrease. Zoninq - Table 4.2.1-4 shows the status of land use planning, zoning, and subdivision ordinances for the Six-County Socioeconomic Study Area. Information is cited for all cities and towns with at least 10,000 residents as of July 1997 as well as for all six counties.

W:\PIEDMONT\DEIS\CH 4\S 4-2\Tbls\T 421-4\03/09/00 Alamance County have enacted zoning and subdivision ordinances as of August 1999. Many of the jurisdictions have adopted land use or comprehensive plans or now are in the process of developing either a land use or comprehensive plan. 4.2.1.3 Generalized Study Area Existing Land Use - The Generalized Study Area is the area surrounding PTIA that is within 5 miles from the end of any the proposed runways for all of the project alternatives. Figure 4.2.1-1 shows land use in the Generalized Study Area. The first step in creating the Generalized Study Area was to map all the runway alternatives and then extend the study area for 5 miles from the end of each runway. The runway study areas were then enclosed within a square to form the Generalized Study Area. Approximately 67 percent of the land not owned by PTIA lies within the City of Greensboro, 22 percent lies within the unincorporated area of Guilford County, and 11 percent lies within the City of High Point. Table 4.2.1-5 states the general building types within the Generalized Study Area. There are 52 airport-related buildings; 2,650 commercial, industrial, warehouse, and office buildings; 17,215 single-family homes; 2,684 multi-family, condominium, or townhouse buildings with 11,400 units; 13 churches; 7 fire stations; 51 nursing home buildings; 5 post office buildings; 35 prison buildings; 177 school buildings; 8 community facility buildings; and 182 industrial petroleum storage tanks within the Generalized Study Area. Zoning -The cities of Greensboro and High Point and Guilford County have zoning and planning authority over land use within their jurisdictions in the DEIS Generalized Study Area. Zoning regulation has a long- standing tradition in the region. Greensboro adopted its first official zoning map and ordinance in the 1920's and adopted its first subdivision ordinance in the 1940's. The City of Greensboro does not have a comprehensive land use plan. The City of High Point also adopted its first zoning map and ordinance in the 1920's and followed with a subdivision ordinance. The City of High Point is currently updating its 1992 Land Use Plan and in June 1995 adopted the West Wendover Avenue/Guilford College Road Corridor Plan. This corridor plan covers some of the road corridors located in the Generalized Study Area. High Point is now preparing a similar corridor plan for the Johnson Street/Sandy Ridge Road area located in the Generalized Study Area, although the High Point City Council has not adopted this plan as of January 10, 2000. Guilford County first adopted an official zoning map and ordinance in March 1964, and in 1966 the county adopted its first subdivision ordinance. The first and only county Comprehensive Plan was adopted in 1986. The Northwest Area Plan was adopted by the Guilford County Board of Commissioners in April 1998, and is an amendment to the county's Comprehensive Plan. The Northwest Area Plan proposes to change the current urban sprawl pattern and to create a new development pattern that includes town service cores, the town development area, and preservation of the outer rural areas (Guilford County Planning Department, May 1998). The northwest portion of the Generalized Study Area is included as part of this plan. WAPIEDMONnDEIS\Ch 4\S_4.doc 4-3 Chapter 4.0 Affected Environment In 1990, Guilford County, the cities of High Point and Greensboro, and the nearby towns of Gibsonville and Jamestown began to create a Multi-jurisdictional Unified Development Ordinance (UDO). The objective of the UDO is to modernize the land use regulations and to standardize the development regulations among the jurisdictions to reduce confusion, avoid significant changes when property is annexed, and avoid development conflicts as the cities grow together. By 1992, Guilford County, High Point, and Greensboro had adopted versions of the UDO (Guilford County, August 16, 1999). The zoning and overlay districts that fall within the Generalized Study Area are summarized below. The majority of the zoning regulations are the same, yet there are significant local variations. AGRICULTURAL DISTRICT: The Agricultural District is primarily intended to accommodate uses of an agricultural nature, including farm residences and farm tenant housing. It also accommodates scattered non-farm residences on large tracts of land. It is not intended for major residential subdivisions. The district is established to preserve and encourage the continued use of land for agricultural, forest, and open space purposes; to discourage scattered commercial and industrial land uses; to concentrate urban development in and around area growth centers, thereby avoiding premature conversion of farmland to urban uses; and to discourage any use that, because of its character, would create premature or extraordinary public infrastructure and service demands. SINGLE-FAMILY RESIDENTIAL: The various single-family residential districts are characterized by the minimum lot size and whether access to public water and wastewater services is required. The minimum lot sizes range from 1.0 unit per acre or less in the RS-40 district to 7.0 units per acre in the RS-5 district. Basically, the higher density residential districts with more than 1.9 units per acre require that public water and wastewater services be provided, while the lower residential density districts do not. The overall gross density ranges from 1.0 unit per acre or less in the RS-40 single-family district to 7.0 units per acre in the RS-5 residential district. MULTI-FAMILY RESIDENTIAL: The various multi-family districts are characterized by the number of dwelling units per gross acre and the type of housing unit permitted. Duplexes, twin-homes, townhouses, cluster housing, and apartments are classified as multi-family structures. The maximum overall density ranges from 5.0 units per acre to 26.0 units per acre. Public water and sewer service is required in all multi- family districts. OFFICE AND COMMERCIAL: There are several office and commercial districts that vary according to the intensity and density of development. Types of commercial zoning districts include the Neighborhood Business District, Limited Business District, General Business District, Highway Business District, Central Business District, and a Shopping Center District. CORPORATE PARK DISTRICT: The Corporate Park District is intended to accommodate office, warehouse, research and development, and assembly uses on large sites in a planned, campus-like setting compatible with adjacent residential uses. The Piedmont Center in High Point is an example of a Corporate Park District. LIGHT INDUSTRIAL DISTRICT: The Light Industrial District is primarily intended to accommodate limited manufacturing, wholesaling, warehousing, research and WAPIEDM0NTDEIS\Ch_4\S_4.doc 4-4 Chapter 4.0 Affected Environment TABLE 4.2.1-5 1999 HOUSING AND LAND USE CHARACTERISTICS OF THE GENERALIZED AND DETAILED STUDY AREAS Piedmont Triad International Airport Environmental Impact Statement Number of Buildings Building Type Detailed Study Area `Generalized Stud Area Airport, Terminal, and Parkin 52 52 Commercial/Industrial/Warehouse/Office 495 2,650 Single-Family Residential 922 17,215 Single-Family Auxiliary 227 6,217 Multi-Family Residential 67 2,684 Church 2 13 Fire Station 2 7 Nursing Home 0 51 Post Office 0 5 Prison 0 35 School 21 177 Community Facilities 0 8 Tanks 30 182 Utilities 2 2 Unknown/ Additions 0 22 TOTAL 1,820 29,320 Sources: Housing and building count compiled by Hayes & Associates and URS Greiner Woodward Clyde, Inc. \\c1 MO1 \wp_wpro\PI EDMONT\DEIS\Ch_4\T_4-2\T_421-5.dod03/09/00 development, and related commercial/service activities that, in their normal operations, have little or no adverse effect upon adjoining properties. HEAVY INDUSTRIAL DISTRICT: The Heavy Industrial District is primarily intended to accommodate a wide range of assembling, fabricating, and manufacturing activities. The district is established for the purpose of providing appropriate locations and development regulations for uses that may have significant environmental impacts or require special measures to ensure compatibility with adjoining properties. PUBLIC AND INSTITUTIONAL: The Public and Institutional District is intended to accommodate mid- and large-sized public, semi-public, and institutional uses that have a substantial land use impact or traffic generation potential. It is not intended for smaller public and institutional uses customarily found within residential areas. PLANNED UNIT DEVELOPMENT - RESIDENTIAL: This district is intended to accommodate a variety of housing types developed on large tracts in accordance with a Unified Development Plan. The PD-R District also accommodates neighborhood business and office uses that primarily serve nearby residents. The Cardinal Country Club is an example of a Planned Unit Development (PUD). Overlay districts establish certain area regulations that are in addition to the underlying general use, planned unit development, or conditional use district(s). The following are overlay districts that are located within the Generalized Study Area. • AIRPORT DISTRICT: The Airport Overlay District, previously discussed in the Detailed Study Area section, is intended to prohibit the construction of structures that would, by virtue of their height, interfere with operations at PTIA. The district is also intended to keep residential densities near the airport very low to minimize the negative effects of aircraft noise on homes. • WATERSHED CRITICAL AREA DISTRICT: The Watershed Critical Area Overlay District is intended to set forth regulations for the protection of public drinking water supplies and is applicable to all lands adjacent to, and that drain toward, existing or proposed water supply intakes or reservoirs. • GENERAL WATERSHED AREA DISTRICT: The General Watershed Overlay District is intended to set forth regulations for the protection of public drinking water supplies and are applicable to all lands that drain toward such supplies and are outside of the WCA Overlay District. • FLOOD HAZARD DISTRICT: The Flood Hazard Overlay District is intended to set forth regulations that will minimize the damage done by floods. • SCENIC CORRIDOR DISTRICT: The Scenic Corridor Overlay District is intended to set forth regulations that will enhance the attractiveness of major thoroughfares that enter and/or pass through Guilford County. These regulations are specified in Section 4-11 (Overlay District Requirements). Portions of both SR 68 and Interstate 40 are designated as scenic corridors within the Generalized Study Area. • MANUFACTURED HOUSING DISTRICT: The Manufactured Housing Overlay District is intended to set forth regulations governing the development of subdivisions for manufactured housing in certain areas of Guilford County. WAPIEDM0NnDEIS\Ch_4\S_4.doc 4-5 Chapter 4.0 Affected Environment 4.2.1.4 Detailed Study Area Existing Land Use - The Detailed Study Area is the proximate area surrounding PTIA that could be built upon by one or more of the project alternatives. Figure 4.2.1-1 shows land use in the Detailed Study Area. Mapping all construction areas for each project alternative and then enclosing all of the construction sites within a square creates the Detailed Study Area. Not all of the land within the Detailed Study Area would be affected by airport construction. Approximately 70 percent of the land not owned by PTIA lies within the City of Greensboro and 30 percent lies within the unincorporated area of Guilford County. Table 4.2.1-5 states the general building types within the Detailed Study Area. There are 52 airport- related buildings on airport property; 495 commercial, industrial, warehouse, and office buildings; 922 single-family homes; 67 multi-family, condominium, or townhouse buildings with 1,190 units; 2 churches; 2 fire stations; 21 school buildings; and 30 industrial petroleum storage tanks within the Detailed Study Area. Zoning - PTIA is a quasi-municipal entity, based upon state law, located within a state-defined boundary that may not be annexed by neighboring cities. Consequently, PTIA operates as an unincorporated entity of Guilford County. Guilford County has elected not to exert zoning or subdivision authority over the airport property. The properties bordering the airport to the east, south, and southwest are within the City of Greensboro. Guilford County governs properties adjacent to the airport on the north and northwest. The zoning districts for these jurisdictions are described in the following section about the Generalized Study Area. Greensboro, High Point, and Guilford County have enacted an Airport Overlay District that prohibits the construction of structures that would, by virtue of their height, interfere with operations at PTIA. The overlay district is also intended to keep residential densities low near the airport to minimize the negative effects of airport noise on homes. The local governments periodically revise the boundaries of the overlay district as new airport noise contours are established with updates of the Airport Master Plan. The zoning for the Detailed Study Area is shown on Figure 4.2.1-2. There are slight variations in the Airport Overlay District regulations among the jurisdictions. The cities of High Point and Greensboro established both a DNL 65 dBA Noise Contour Area and an Approach Zone Area. The DNL 65 dBA Noise Contour Area is delineated on the Off-Airport Land Use Plan in the PTIA Master Plan. No residential uses are permitted, except single-family detached dwellings on lots that are 40,000 square feet or larger in size. The Approach Zone Area lies within the DNL 65 dBA Noise Contour Area and consists of the approach zones delineated on the Approach and Clear Zone Plan in the PTIA Master Plan. Places of public assembly such as schools, churches, theaters, auditoriums, and coliseums shall not be constructed or otherwise located in the Approach Zone Area (City of Greensboro, August 17, 1999). The Guilford County Airport Overlay District regulates the height limits of structures within the Approach and Clear Zone and states that no residential uses shall be permitted within the DNL 65 dBA Noise Contour, except for single-family homes on lots that meet or exceed the requirements of the RS-40 zone (Guilford County, August 16, 1999). WAPIEDM0NT\DEIS\Ch_4\S_4.d0c 4-6 Chapter 4.0 Affected Environment 1986 Airport Land Use Plan and Forthcoming Update - The Guilford County Board of Commissioners adopted its first Airport Area Plan in 1986. The purpose of the plan was to recommend a general pattern of land use, utility provision, and environmental protection in the area surrounding the airport that would permit continued development without adversely affecting airport operations. In July 1999, Guilford County, in cooperation with Forsyth County, Greensboro, High Point, and Kernersville, initiated a citizen-based planning process to examine land use, transportation, facilities/utilities, and environmental factors in the PTIA area. The plan will recommend a development pattern that will be compatible with proposed airport improvements and will mitigate the impact of these improvements on the surrounding area. The intended product of the study is a plan that can be adopted by Guilford County, Forsyth County, Greensboro, High Point, and Kernersville as a guide to development as the Mid-Atlantic Hub is built and businesses move to the area. The update is projected to be a 15- to 18-month planning project, and the target completion date is January 1, 2001 (Guilford County Planning Department, August 16, 1999). 4.2.2 SOCIOECONOMICS /DEMOGRAPHICS 4.2.2.1 Socioeconomics Employment Distribution - Guilford and Forsyth counties dominate the regional economy as shown in Table 4.2.2-1. In 1996, 42 percent of all wage and salary employees in the Six-County Socioeconomic Study Area worked in Guilford County and 27.3 percent worked in Forsyth County. Each of the remaining four counties had less than 10 percent of the regional employment. Employment growth has been steady in the Six-County Socioeconomic Study Area increasing from a total of 483,356 wage and salary employees in 1980, to 661,411 workers in 1996, which is an increase of 178,055 workers over the 16- year period and represents a 36.8 percent increase. From 1970 through 1996 and continuing years, employment distribution throughout the Six-County Socioeconomic Study Area has shown a marked trend from an industrial to a service economy as shown on Table 4.2.2-2. In 1970, 41.6 percent of employment in the region was in the manufacturing sector, while 14.5 percent was in the services sector. By 1996, manufacturing had decreased to 23.4 percent of the wage and salary employment, while services had increased to 27 percent. Retail trade accounted for 17.1 percent of the 1996 total wage and salary employment. The 1996 employment by the government sector was 9.2 percent of the total employment. Each of the remaining economic sectors had 6 percent or less of the 1996 employment. Economic Base of the Six-County Socioeconomic Study Area - Comparing the individual counties of the Six-County Socioeconomic Study Area to the state as a whole indicated where relative economic strengths are concentrated. Using data for 1986 and 1996, location quotients for major economic sectors revealed which of these sectors act as "basic" or export sectors within the regional economy. The location quotients use Bureau of Economic Analysis (BEA) numbers for individual counties, for the Piedmont Triad Region, and for the state. Generally, a sector of the economy is classified as an WAPIEDM0N1IDEIS\Ch_4\S_4.doc 4-7 Chapter 4.0 Affected Environment exporting component if the location quotient is greater than one, indicating that these sectors are considered a strength and specialty for the local economy. Location quotients with a value equal to one indicate that the local employment sector is similar to that of the state and southeast regional employment values and that the sector is considered to be at "equilibrium." Import sectors with location quotients less than one indicates that the local employment in that sector is less than the state and national values and that this sector is relatively weak in the local economy. As an example, data for Guilford County indicate relative strength in the transportation; wholesale trade; finance and, to some degree, in the services sectors. Economic strength has been increasing in transportation. Retail trade is slightly under-served; manufacturing is comparable to the state as a whole. In comparison, Forsyth County data indicate relative strength in transportation, finance, and services. Retail trade is virtually on par with the state as a whole. Both the finance and services sector appear to be growing in relative strength. The government sector is relatively weak. The Six-County Socioeconomic Study Area as a whole shows relative strength in manufacturing, transportation, wholesale trade, and services. Increasing concentration of employment is indicated in both the transportation and services sectors. The retail trade sector is on par with state characteristics, while manufacturing remains relatively strong in the region. In contrast, the government sector is relatively weak in comparison to the state, while construction is also virtually on par with the state as a whole. The finance sector indicates some potential for increasing relative strength. Table 4.2.2-3 summarizes relatively strong, growing, and weak sectors for the Six-County Socioeconomic Study Area and individual counties. Table 4.2.2-4 is a listing of the top 10 major employers for the Six-County Socioeconomic Study Area, which are also the top 10 employers for the Piedmont Region as a whole. These top 10 industries together employ approximately 62,300 or 8 percent of the total wage and salary employment in the Piedmont Triad Region, indicating again how centralized the regional economy has been in the past. In general, the list of the 10 employers in particular and the list of major employers in general reinforce the conclusions of the economic base analysis for the Six-County Socioeconomic Study Area as a whole. That analysis indicates regional strength in manufacturing, transportation, wholesale trade, and services-all of which are well represented on the list of major employers. Unemployment Rate - The annual average unemployment rate for the Six-County Socioeconomic Study Area was lower than both the state and national rates in 1998 as shown in Table 4.2.2-5. The area's 1998 unemployment rate was 2.9 percent as compared to the state rate of 3.5 percent and the national rate of 4.5 percent. Both Guilford and Forsyth counties had the lowest unemployment rates at 2.6 percent. Rockingham County had the highest rate at 5.2 percent (North Carolina's Employment Security Commission, May 13, 1999). Average Wages - Table 4.2.2-6 states the 1997 average weekly wages for the dominant industries for each of the six counties as well as the 1996 average annual wages. The urbanized counties of Forsyth and Guilford have higher weekly and annual wages than the state average with the exception of business WAPIEDMONl1DEIS\Ch_4\S_4.doc 4-8 Chapter 4.0 Affected Environment TABLE 4.2.2-1 WAGE AND SALARY EMPLOYMENT FOR THE SIX-COUNTY SOCIOECONOMIC STUDY AREA, 1980 TO 1996 Piedmont Triad International Airport Environmental Impact Statement Year Alamance County Davidson Count Forsyth Count Guilford Count:' Randolph Count: Rockingham Courlt Total 1980 45,274 40,917 134,506 193,816 35,175 33,668 483,356 1981 45,870 42,038 136,304 196,178 35,555 33,175 489,120 1982 45,202 40,488 134,417 193,637 35,156 31,840 480,740 1983 46,025 41,722 135,175 199,566 35,437 32,273 490,198 1984 48,653 44,431 143,240 212,074 38,318 33,206 519,922 1985 49,769 44,955 149,402 217,360 38,812 32,544 532,842 1986 51,735 45,025 153,003 225,366 39,938 32,260 547,327 1987 55,036 47,498 158,142 237,252 41,183 33,124 572,235 1988 57,873 49,121 164,877 244,279 43,303 34,231 593,684 1989 58,903 49,622 165,513 247,327 44,081 34,353 599,799 1990 58,754 49,803 166,124 248,591 44,419 34,655 602,346 1991 57,242 49,094 163,107 242,264 43,783 34,699 590,189 1992 58,166 50,039 164,341 244,808 45,388 34,684 597,426 1993 59,199 50,466 168,061 253,136 47,032 35,551 613,445 1994 60,530 51,726 173,608 262,297 48,654 36,653 633,468 1995 61,574 51,838 177,652 271,137 49,783 37,226 649,210 1996 63,251 52,051 180,728 277,938 49,867 37,576 661,411 Percent of 1996 Total 9.6% 7.9% 27.3% 42.0% 7.5% 5.7% 100.0% Wage and salary employment refers to all employment covered by state unemployment insurance (UI) and unemployment compensation for Federal employees (UCFE).

The 1997 weekly wage for Forsyth County was $574.42 and for Guilford County was $546.58, which are higher than the state average weekly wage of $512.79. The 1996 annual average wage followed a similar pattern. Both urban counties have average annual wages ranging from $28,497 for Forsyth County, to $27,569 for Guilford County, which are higher than the state average of $25,283. Only the 1997 business sector wages in the urban counties were lower than the state average. The 1997 weekly wages for the business sector were $327.62 for Forsyth County and $353.15 for Guilford County in comparison to $416.10 for the State of North Carolina. In marked contrast, the outlying counties of Alamance, Davidson, Randolph, and Rockingham counties had lower weekly and annual wages than the state average salaries. 4.2.2.2 Demographics Six-County Socioeconomic Study Area Recent Population Trends - Population trends from 1970 through 1997 for the Six-County Socioeconomic Study Area are shown in Table 4.2.2-7. The Six-County Socioeconomic Study Area as a whole has experienced a modest rate of growth since 1970. According to the 1990 Census, the Six- County Socioeconomic Study Area experienced a 23.4 percent population growth rate between 1970 and 1990, with a net population increase of 197,111 residents. Modest population growth continued between 1990 and 1997 with the addition of 100,516 more residents. As shown on Table 4.2.2-8, approximately 38.6 percent of this growth is a result of natural increase (births exceeding death), and the remaining 61.4 percent is attributed to net migration. The urbanized counties of Guilford and Forsyth experienced the largest net increase in population as shown on Table 4.2.2-7. Between 1970 and 1997, Guilford County gained 94,596 residents, and Forsyth County grew by 72,812 residents. Davidson and Randolph counties experienced similar net population increases of 44,815 and 45,192 residents, respectively, during this 27-year period. Alamance County gained 23,458 residents and Rockingham County gained 16,754 residents. Of the six counties, Randolph County with a 32.5 percent increase in population between 1970 through 1997 experienced the greatest change in population growth; however, this rate of growth was lower than the statewide growth of 46.2 percent. Rockingham County had the lowest percent change in population with only a 6.9 percent increase. The remaining four counties experienced modest population growth ranging from 17.8 percent for Forsyth County to 24.1 percent for Davidson County. Racial Composition - As shown on Table 4.2.2-9, four out of the six counties, the Six-County Socioeconomic Study Area as a whole, and the state of North Carolina have higher percentages of black population than the United States according to the 1990 Census. Nearly 21 percent of the region's 1990 population was black as compared to 22 percent for the state of North Carolina and 12 percent for the United States. In 1990, the Six-County Socioeconomic Study Area as a whole had a racial composition similar to that of the state with nearly 78 percent of the population white, 20.6 percent black, and only 1.1 percent American Indian, Asian, or other races. The urbanized counties of Forsyth and Guilford have W.\PIEDM0NTDEIS\Ch_4\S_4.d0c 4-9 Chapter 4.0 Affected Environment higher percentages of black population than either the state or the nation. In contrast, the rural counties of Davidson and Randolph have lower percentages of black population than either the state or nation with only 9.6 percent and 5.8 percent, respectively. The 1990 American Indian population was only 0.3 percent for the Six-County region as compared to 1.2 percent for North Carolina. As of 1990, the Six- County Socioeconomic Study Area had only 0.7 percent Hispanic population as compared to 1 percent of the state and 8.8 percent for the nation. According to the 1990 Census, only 1.3 percent of the Six- County region's population could not speak English well. Age Distribution - Age characteristics for the Six-County Socioeconomic Study Area are shown on Table 4.2.2-10. According to the U.S. Census, all six counties individually as well as the Six-County Socioeconomic Study Area as a whole have a slightly higher average age than the state of North Carolina and the nation. The average age in 1990 was 37.7 years for Alamance County, 36.2 years for Davidson County, 36.1 years for Forsyth County, 35.8 years for Guilford County, 36.0 years for Randolph County, and 37.3 years for Rockingham County. The average age for the Six-County Socioeconomic Study Area is 36.3 years, as compared to 35.5 years for the state of North Carolina and 35.3 years for the nation. The slightly higher average age for the Six-County Socioeconomic Study Area is attributed to the fact that the region has slightly fewer children under 17, and slightly higher percentage of adults aged 45 to 64 than either the state or the nation. Income Distribution - As shown in Table 4.2.2-11, income levels for most Six-County Socioeconomic Study Area households are lower than the median and average household incomes for the nation but higher than the median and average household incomes for the state of North Carolina. The United States 1990 median household income was $30,056, in contrast to $26,647 for the state, and $28,045 for the six-county region. The percent of population in poverty is another indicator of income distribution. The Six-County Socioeconomic Study Area has 9.8 percent of its population living in poverty-a rate that is lower than that for either the state of North Carolina (12.5 percent) or the United States (12.8 percent). Educational Attainment - As shown in Table 4.2.2-12, the education attainment levels for the Six-County Socioeconomic Study Area are comparable to those for both the state and the nation. Based on 1990 U.S. Census data, nearly 30 percent of the adults age 25 and over in the Six-County Socioeconomic Study Area, the state of North Carolina, and the nation were high school graduates. Both the Six-County Socioeconomic Study Area and the state have approximately 29 to 30 percent of the adult population lacking a high school degree, which is higher than the national rate of 24.8 percent. Likewise, the Six- County Socioeconomic Study Area and the state have nearly 17 percent of persons age 25 or over with some type of college education. This is a lower percentage than the national rate of 18.7 percent. Approximately 24 to 27 percent of adults age 25 and over in the region, the state, and the nation were college graduates. Generalized Study Area Population - Table 4.2.2-13 states the 1999 housing and population estimates for the Generalized Study Area. As of 1999, there are 28,615 single-family homes and multi-family units, condominiums, and WAPIEDMONT0EIS\Ch_4\S_4.doc 4-10 Chapter 4.0 Affected Environment N N W MJ W Q H n rn o?

It is estimated that there are 65,398 persons residing in the 28,392 occupied dwelling units and nursing home/ retirement facilities. Of these, 66.9 percent live within the City of Greensboro, 21.9 percent live within Guilford County, and 11.2 percent live within the City of High Point. Racial Composition - The racial composition of the Generalized Study Area is shown on Table 4.2.2-14. Approximately 57,535 out of the area's 65,398 residents are white, 6,768 are black, 225 are American Indian, 747 are Asian Pacific, and 123 are other races. The percentage breakdown for the Generalized Study Area reveals that this area is predominately white. The white population comprises 88.1 percent of the area's total population, the black population is 10.3 percent, and the combined percentage of American Indians, Asians, and other races is 1.6 percent. There are 555 Hispanics living in the Generalized Study Area comprising less than one percent of the area's total population. As shown on Table 4.2.2-14, the Generalized Study Area has a larger percentage white population and a smaller minority and Hispanic population than the Six-County Socioeconomic Study Area, the State of North Carolina, or the United States. Age Distribution - Age characteristics of the Generalized Study Area are shown on Table 4.2.2-15. The Generalized Study Area has 13,533 children under 18 years old comprising 20.7 percent of the total population. This is a lower percentage of children under 18 as compared to the Six-County Socioeconomic Study Area, North Carolina, or the United States. The Generalized Study Area also has lower percentages of people aged 65 and over than does the Six-County Socioeconomic Study Area, North Carolina, or the United States. On the other hand, the Generalized Study Area has higher percentages of residents ages 25 to 34 and 35 to 44 than does the Six-County Socioeconomic Study Area, North Carolina, or the United States. Income Distribution - The household income distribution characteristics for the Generalized Study Area are shown in Table 4.2.2-16. Most households in the Generalized Study Area earn more income than their counterparts in the Six-County Socioeconomic Study Area, the state, or the nation. The Generalized Study Area has lower percentages of households earning less than $35,000 and higher percentages of households earning greater than $35,00 than does the Six-County Socioeconomic Study Area, the state, or the nation. Another income indicator is the percentage of population and families living in poverty. The US Census uses a set of money income thresholds that vary by family size and composition to define whom is poor. If a family's total income is less than that family's threshold, then that family, and every individual in it, is considered poor. The poverty thresholds do not vary geographically. The official poverty definition counts money income before taxes and excludes capital gains and noncash benefits (such as public housing, Medicaid, and food stamps). (U.S. Census Bureau, August 31, 1999). Only 7.0 percent of the Generalized Study Area's population is classified as being below the poverty level as compared to 9.8 percent of the Six-County Socioeconomic Study Area's population, 12.5 percent of the state population, and 12.8 percent of the United States population. Educational Attainment - As shown in Table 4.2.2-17, the educational attainment of adults ages 25 and over is far higher in the Generalized Study Area than their counterparts in the Six-County Socioeconomic W:\PIEDM0NT\DEIS\Ch_4\S_4.doc 4-11 Chapter 4.0 Affected Environment Study Area, the state, or the nation. Forty-three percent of the adults age 25 and over have a college degree or higher who reside in the Generalized Study Area as compared to only 25.1 percent for the Six- County Socioeconomic Study Area, 24.2 percent for the state, and 26.5 percent in the nation. Not surprisingly, the percentage of adults not completing high school or only being high school graduates is far lower in the Generalized Study Area than for the Six-County Socioeconomic Study Area, the state, or the nation. Only 13.8 percent of the adults age 25 or over in the Generalized Study Area did not complete high school as compared to 28.7 percent in the Six-County Socioeconomic Study Area, 30.0 percent in the state, and 24.8 percent in the nation. Detailed Study Area Population - Table 4.2.2-13 states the 1999 housing and population estimates for the Detailed Study Area. As of 1999, there are 2,112 single-family homes and multi-family units, condominiums, and townhomes within the Detailed Study Area. It is estimated that there are 4,756 persons residing in the 1,996 occupied dwelling units. Of these, 71 percent live within the City of Greensboro and 29.0 percent live within Guilford County. Racial Composition - The racial composition of the Detailed Study Area is shown on Table 4.2.2-14. Approximately 4,096 out of the area's 4,756 residents are white, 570 are black, 20 are American Indian, 59 are Asian Pacific, and 11 are other races. The percentage breakdown for the Detailed Study Area reveals that this area is predominately white. The white population comprises 86.2 percent of the area's total population, the black population is 12 percent, and the combined percentage of American Indians, Asians, and other races is 1.8 percent. There are 40 Hispanics living in the Detailed Study Area comprising less than 1 percent of the area's total population. As shown on Table 4.2.2-14, the Detailed Study Area has a larger percentage white population and a smaller minority and Hispanic population than the Six-County Socioeconomic Study Area, the State of North Carolina, or the United States. Age Distribution - Age characteristics of the Detailed Study Area are shown on Table 4.2.2-15. The Detailed Study Area has 978 children under 18 years old comprising 20.6 percent of the total population. This is a lower percentage of children under 18 as compared to the Six-County Socioeconomic Study Area, North Carolina, or the United States. The Detailed Study Area also has a lower percentage of people aged 65 and over than does the Six-County Socioeconomic Study Area, North Carolina, or the United States. On the other hand, the Detailed Study Area has higher percentages of residents ages 25 to 34 and 35 to 44 than does the Six-County Socioeconomic Study Area, North Carolina, or the United States. Income Distribution - The household income distribution characteristics for the Detailed Study Area are shown in Table 4.2.2-16. Most households in the Detailed Study Area earn more income than their counterparts in the Six-County Socioeconomic Study Area, the state, or the nation. The Detailed Study Area has lower percentages of households earning less than $35,000 and higher percentages of households earning greater than $35,000 than does the Six-County Socioeconomic Study Area, the state, or the nation. Another income indicator is the percentage of population and families living in poverty.

(U.S. Census Bureau, August 31, 1999). Only 8.1 percent of the Detailed Study Area's population is classified as being below the poverty level as compared to 9.8 percent of the Six-County Socioeconomic Study Area's population, 12.5 percent of the state population, and 12.8 percent of the United States population. Educational Attainment - As shown on Table 4.2.2-17, the educational attainment of adults ages 25 and over is far higher than their counterparts in the Six-County Socioeconomic Study Area, the state, or the nation. Over 40 percent of the Detailed Study Area adults age 25 and over have a college degree or higher as compared to only 25.1 percent for the Six-County Socioeconomic Study Area, 24.2 percent for the state, and 26.5 percent in the nation. Not surprisingly, the percentage of adults not completing high school or only being high school graduates is far lower in the Detailed Study Area than for the Six-County Socioeconomic Study Area, the state, or the nation. Only 15.1 percent of the adults age 25 or over in the Detailed Study Area did not complete high school as compared to 28.7 percent in the Six-County Socioeconomic Study Area, 30.0 percent in the state, and 24.8 percent in the nation. 4.2.3 SECTION 303(0) TITLE 49 U.S. CODE AND U.S. DO/ SECTION 6(F) RESOURCES 4.2.3.1 Section 303(c) Properties Section 303(c), Title 49 U.S. Code, commonly referred to as Section 4(f), provides protection for special properties, including significant publicly owned parks, recreation areas, wildlife and waterfowl refuges, or any significant historic and archeological sites. Protection also applies to all cultural resource sites on, or eligible for, inclusion on the National Register of Historic Places (36 Code of Federal Regulations (CFR), Section 60.4). Section 303(c) prevents the approval of a proposed Federal action that requires the use of these special properties unless no feasible and prudent alternative exists and the project includes all possible planning to minimize harm to the resource resulting from such use. For the purposes of Section 303(c) properties, a "use" refers to a permanent acquisition or direct taking of the property or a temporary occupancy of the property that is adverse to the statute's preservationist purposes. Section 303(c) also applies when a "constructive use," or certain indirect uses, of the resource occurs. Table 4.2.3-1 identifies 63 Section 303(c) sites within the Generalized and Detailed Study Areas. Historic and cultural resource properties eligible for protection under Section 303(c) are addressed in Section 4.2.4 of this EIS. These properties include both designated and potentially eligible sites for listing on the National Register of Historic Places. WAPIEDM0Nl1DE1S\Ch_4\S_4.doc 4-13 Chapter 4.0 Affected Environment The following presents a brief overview of each Section 303(c) site within the Generalized and Detailed Study Areas. Included is a description of the size, location, and major features of each site. These sites are depicted on Figure 4.2.3-1. Site No. 1: Amber Natural Area - Amber Natural Area is located between Amber Lane and Random Drive 4.9 miles southeast of PTIA in the City of Greensboro. Zoning surrounding Amber Natural Area is single-family residential. Functionally, the property is classified as a natural area by the City of Greensboro Park and Recreation Department. There are no facilities at this site. Amber Natural Area encompasses 6.28 acres and is wooded on the north side and open on the south side. Site No. 2: Big Tree Park - Big Tree Park is a 4.02-acre natural area located between Big Tree Lane and Shelby Drive, 3.2 miles southeast of PTIA in the City of Greensboro. Zoning surrounding Big Tree Park is multi-family residential to the south, east, and west, and single-family residential to the north. Functionally classified as a natural area, Big Tree Park provides both passive and active recreational opportunities, which include a playground and open space areas. Site No. 3: Brown Bark Park - Brown Bark Park is a 13.64-acre park located between Brown Bark Drive and Watauga Drive 3.9 miles east of PTIA in the City of Greensboro.

The act requires, in part, that: "No property acquired or developed with assistance under this section shall, without approval of the Secretary of the Interior, be converted to other than public outdoor recreation uses." There are no properties within the Generalized or Detailed Study Areas identified as Section 6(f) resources. 4.2.4 HISTORIC AND ARCHAEOLOGICAL RESOURCES 4.2.4.1 Compliance with Section 106 of the National Historic Preservation Act Historic and archaeological resources that are listed or eligible for listing in the National Register of Historic Places, that may be affected by an undertaking by a Federal agency, are given a measure of protection by Federal law, primarily the National Historic Preservation Act of 1966 (NHPA), as amended, and its implementing regulations, 36 CFR 800 (June 1999). These laws and regulations are invoked by the involvement of Federal funding, licensing, or permitting. Under the authority of Section 106 of the NHPA, the FAA, prior to the approval of an ALP and issuance of a grant for and funding of an WAPIEDM0NT\DEIS\Ch_4\S_4.doc 4-22 Chapter 4.0 Affected Environment undertaking--specifically, a proposed airport improvement--must take into account the effect the undertaking may have on properties listed in or eligible for listing in the National Register. 4.2.4.2 Historic Architectural Resources Area of Potential Effect To determine the effect an undertaking may have on properties listed or eligible for listing on the National Register, an Area of Potential Effect (APE) must be identified. The APE is the geographic area or areas within which an undertaking may directly or indirectly cause changes in the character or use of historic properties, if any such properties exist (36 CFR 800.16(d)). Such changes may include physical destruction, damage, or alteration of a property; change of the character of the property's use or of physical features within its setting that contribute to its historic significance; and introduction of visual, atmospheric, or audible elements that diminish the integrity of the property's significant historic features (36 CFR 800.5(a)(2). Based on these factors, the APE associated with historic architectural resources for the proposed PTIA improvements includes the limits of disturbance associated with these improvements and those locations that would newly fall within the 65 DNL noise contour as a result of the proposed project. The DNL is a scientifically modeled level of sound that has been shown to be directly linked to human beings and "annoyance level." Location outside the 65 DNL is considered compatible with land uses that include residential, educational, religious, medical, and outdoor recreational. The use of the 65 DNL contour to define an APE for historic architectural resources is based on accepted FAA land-use compatibility guidelines (Federal Interagency Committee on Urban Noise, 1980) and recent court decisions. The historic architectural APE for the project, which falls between the current 65 DNL noise contour and the combined 65 DNL noise contours for each of the project alternatives, is pictured in Figure 4.2.4-1. The APE also includes property that would be physically taken or impacted by the project (See Figures 3.4-1 through 3.4-6) 4.2.4.3 Archaeological Resources Area of Potential Effect The APE for archaeological resources is defined as all locations associated with the proposed undertaking that will result in the alteration and disturbance of surface and subsurface soils that contain or have the potential to contain archaeological sites. Therefore, the APE for the proposed improvements was established as the limits of disturbance associated with the proposed project. 4.2.4.4 Historic Architectural Investigations Research conducted at the North Carolina State Office of Historic Preservation (SHPO) in Raleigh identified 11 previously inventoried standing resources more than 50 years old that are located within the APE for historic architectural resources. Two of these resources are listed in the National Register of WAPIEDM0Nl1DEIS\Ch_4\S_4.d0c 4-28 Chapter 4.0 Affected Environment Historic Places and three have been determined eligible for National Register listing. Five-including two of the eligible resources-were inventoried by Langdon Edmunds Oppermann in 1991 as part of the historic architectural survey of the proposed Greensboro Western Urban Loop (Oppermann 1991). Three were inventoried by R.S. Webb & Associates in 1998 as part of a cultural resources survey of undeveloped portions (390 acres) of the Piedmont Triad Airport Site (G.S. Keith and R.S. Webb to Mark Morgan of Law Engineering and Environmental Services, Inc., May 27, 1998). Fieldwork in October, 1999, and March, 2000, for this project identified an additional 37 historic architectural resources more than 50 years old within the APE, bringing the total number of standing resources within the APE to 48. In sum, two resources-the Guilford College Historic District and the Shaw-Cude House-are listed in the National Register and three resources-the New Garden Friends Cemetery, the Campbell-Gray Farm, and the Roy Edgerton House-have been determined eligible for National Register listing. Following the fieldwork and its assessment, the FAA determined that there are no additional historic architectural resources within the APE that are eligible for listing in the National Register. The FAA will consult with the North Carolina SHPO concerning its determinations of eligibility following SHPO review of the historic architectural surrey report prepared in association with the inventory of the APE. Following are brief assessments of the 48 resources. These resources and the project's APE are identified in Figure 4.2.4-1.

The overview summarized the considerable archaeological research that has been conducted in the general vicinity of the Detailed Study Area within the past 3 decades. It also noted archaeological sites on PTIA property previously identified in three archaeological investigations (Dorwin, 1977; Woodall, 1978; G.F. Keith and R.S. Webb to Mark Morgan of Law Engineering and Environmental Services, Inc., May 27, 1998). According to this overview, the most common prehistoric sites identified within the vicinity of PTIA consist of sparse scatters of prehistoric lithic artifacts. In most cases these assemblages lack diagnostic artifacts and cannot be assigned to a specific period. No Paleoindian sites have been previously recorded in the general vicinity of PTIA. Archaic sites (8000 - 1000 BC) are more commonly identified in the region, particularly in upland settings, frequently at the tops of knolls overlooking stream confluences. Woodland sites (1000 BC - 1700 AD) are also likely to be located in upland settings and on the floodplains of streams and rivers. Although the airport property lacks broad floodplains, and many of the narrower floodplains along creeks and streams in the area are poorly drained and swampy, previous archaeological work has identified several woodland sites on airport property, most notably along a low W:\PIEDMONTDEIS\Ch_4\S_4.doc 4-29 Chapter 4.0 Affected Environment rise in the floodplain north of Brush Creek. Similar landforms on airport property are anticipated to contain these types of sites. The overview noted that historic settlement of the study area commenced in the mid eighteenth century. While historic sites in the area dating earlier than the 19th century are quite rare, 19th and early 20th century historic sites are apt to be more common. The area was of strategic importance during both the Revolutionary and the Civil Wars and although considerable research has been conducted at known historic sites, other evidence of military activity would not be unexpected in the region. 4.2.4.6 Program for Compliance with Section 106 of the National Historic Preservation Act The FAA has sent a letter to the North Carolina State Historic Preservation Office (SHPO) to initiate formal consultation regarding the identification, evaluation, and treatment of historic architectural and archaeological resources (Donna M. Meyer to David Brook, August 2, 1999) (copy of letter in Appendix G). The FAA proposed completing the historic architectural survey once the contours have been defined and submitting a report for SHPO review and concurrence prior to the issuance of the DEIS. In regards to archaeological resources, the FAA proposed phasing the project and conducting a full archaeological survey after the completion of the DEIS, but prior to the release of the FEIS, as provided by 36 CFR 800.4(b)(2). This proposal was advanced based on the extant archaeological data base that can be used to adequately evaluate the impacts of the proposed build alternatives on National-Register-eligible archaeological sites. This proposal would also avoid unnecessary archaeological fieldwork and evaluation. The SHPO agreed with the proposal for a phased approach to addressing potential effects to archaeological resources resulting from the airport improvements by a letter to FAA of September 15, 1999 (David Brook to Donna M. Meyer), contained in Appendix G. W.\PIEDM0Nl1DEIS\Ch 4\S_4.doc 4-30 Chapter 4.0 Affected Environment 4.2.5 AIRPORT NOISE 4.2.5.1 Project Description The purpose of this analysis is to evaluate the existing noise exposure at PTIA. The project analysis comprised five parts: 1) measurement of the existing noise environment at PTIA (Section 4.2.5.2), 2) collection of existing operational data (Section 4.2.5.3), 3) development of noise exposure contours for the existing base case, 4) analysis of the existing noise impacts (Section 4.2.5.4), and 5) documentation of the noise environment in accordance with FAA requirements (Section 4.2.5.5). 4.2.5.2 Noise Measurement Program Noise measurements provide important input to an understanding of the existing noise environment. PTIA does not have a permanent noise monitoring system. Therefore, the FAA measured existing noise conditions with portable noise monitors from January 11 through January 20, 1999. These measurements provided the study with information on single event and cumulative noise exposure information and aircraft operations information that was useful for development of the noise contours at PTIA. A summary of the objectives, design, and execution of the portable measurement program and the results, including a summary of the cumulative noise measurements at all measurement sites is provided in Appendix B of this EIS. A comparison between the noise measurement and monitoring programs is discussed in Section 4.2.5.4. In general, the noise measurement results correlated well with the monitoring program results. 4.2.5.3 Development of Operations Input This section contains a description of the process used to prepare the operations data that constitute the input for the 1998 Existing Condition (base case) noise exposure contours and is a basis for all future contours. Contour Preparation Process - The standard approach for preparation of airport noise exposure contours requires compilation of several categories of information about the operation of an airport: • Airport Layout: location, length and orientation of all runways; • Operations Numbers: Numbers of departures, arrivals and pattern operations by each type of aircraft during an "annual average day". The number of operations on this day is the number of operations during the year divided by the number of days in the year. The average daily operations are based on the total operations for the 12- month period between 1 January 1998 and 31 December 1998. The 24-hour day has two parts, the daytime (0700-2200) and the nighttime (2200-0700). The daytime/nighttime distribution is an important data element because nighttime operations are penalized by adding 10 dBA to each aircraft event to account for increased annoyance at night. A detailed description of daytime/nighttime distribution and the DNL metric used in this analysis is contained in Appendix J of this EIS; WAPIEDM0NMEIS\Ch_4\S_4.doc 4-31 Chapter 4.0 Affected Environment • Runway Use: Percentage of operations by each type of aircraft that occur on each runway; • Flight Tracks: Paths followed by aircraft departing from, or arriving to, each runway; and • Flight Track Usage: Percentage of operations by each aircraft type that use each flight track. All of the required operations information were obtained and prepared for input into the FAA-approved airport noise model, the FAA's Integrated Noise Model, Version 5.2a (INM 5.2a). The INM computes the noise exposure around an airport as a grid of values of the Day-Night Sound Level (DNL). The grid information is the input for a contouring program. Description of the Data Input - This section contains the information used to prepare the noise contours. It also cites the sources for the information. Airport Layout - PTIA currently has two paved operational runways: Runways 05/23 and 14/32. Runway 05/23 is 10,001 feet long and Runway 14/32 is 6,380 feet long. Both runways are 150 feet wide. The airport elevation is 927 feet above mean sea level (MSL). These data came from the current Airport Layout Plan (ALP). Operations Numbers - The metric used to account for the total noise at an airport is referred to as the Day-Night Average Sound Level, abbreviated as DNL or Ldn. The annual average DNL noise exposure contours for the 1998 Existing Condition are based on the average daily operations during the most recent 12-month period. Although the noise environment around the airport comes almost entirely from operations of air carrier jet aircraft, the 1998 contours reflect the noise from all types of aircraft operations. Several sources were used for the operations information for 1998. The FAA maintains records of the total numbers of operations during a year and assigns the operations to four categories: air carrier, air taxi, civil or general aviation, and military. Table 4.2.5-1 presents the total 12-month operations data from the FAA Air Traffic Control Tower (ATCT). There are no FAA records of the numbers of operations by type of aircraft or'by time of day. Therefore, the annual operations in the four categories were further disaggregated into the various aircraft types, the number of average daily operations for arrivals and departures, and the number of daytime and nighttime operations as discussed below. The percentages were applied to the total operations in each of the four aircraft categories. The "air carrier" category generally pertains to scheduled air carrier or air cargo turbojet aircraft operating at PTIA. The Official Airline Guide (OAG) airline schedules for 1998 were analyzed. This analysis provided the number of average daily operations, by aircraft type, by time of day, and by stage length. Additional analysis provided a further breakdown into INM aircraft categories for aircraft types such as the B727 which has multiple engine types. WAPIEDMONT\DEIS\Ch 4\S_4.doc 4-32 Chapter 4.0 Affected Environment The "air taxi" category generally refers to scheduled commuter turbine-powered propeller (turboprop) and regional jet aircraft operating at PTIA. The OAG also provided the number of average daily operations, by aircraft type, by time of day, and by stage length for the commuter type aircraft. The "civil" aircraft category refers to unscheduled general aviation type aircraft such as single-engine and twin-engine piston propeller aircraft, other turboprop aircraft, and business turbojet aircraft. The fleet mix and percentage of nighttime operations for the civil operations were developed from discussions with PTIA ATCT personnel. Information on the "military" fleet mix operating at PTIA was provided from FAA ATCT estimates. Table 4.2.5-2 contains the operations data for 1998 for an annual average day. Review of 1999 operations data for PTIA indicates operational numbers are consistent with the levels and trends for 1998 as listed in Table 4.2.5-1. No significant events at PTIA occurred during 1999 that would have resulted in a substantial change in aircraft operations at PTIA. Runway Use - During the modeling process, it is necessary to assign all operations to a specific runway. Although the FAA controls runway use, it does not keep records of which runway is in use. However, the FAA ATCT provided estimates of the runway use by various aircraft category for PTIA. Table 4.2.5-3 contains the estimated runway use percentages for 1998 for an annual average day. Flight Tracks - INM simulates the operation of an airport by "flying" the aircraft along relatively small numbers of flight tracks that represent the large number of flight paths actually used by aircraft. During preparation of noise contours for PTIA, information from the FAA's Automated Radar Terminal System (ARTS) was relied upon to identify the flight paths. Tapes were analyzed from the ARTS system representing several days of flight tracks at PTIA. To help understand the flight tracks used for different groups of operations, tracks are divided into groups according to: 1) type of aircraft -- jet or propeller; 2) type of operation -- departure, arrival, or pattern; and, 3) direction of flow -- east or west. The area covered by a group of flight tracks for aircraft using a single runway and going to a single fix is called a flight "corridor". A flight corridor may be very wide. This characteristic of flight tracks to form a wide corridor is called "dispersion" and is most pronounced for corridors with turns. To model the noise exposure properly, the dispersion must be properly modeled. At PTIA the flight corridors are of different widths and appropriate numbers of flight tracks were developed (based on corridor width) to model each flight corridor. Figure 4.2.5-1 presents representative departure and arrival flight tracks that were used to model the 1998 Existing Condition noise contours. Flight Track Usage - The radar tracks analyzed provided the basis for flight track usage. The percentages of aircraft using each fix established the percentage of operations in each flight corridor and the width of the corridor determined the number of tracks required for modeling. The flight tracks for each WAPIEDMONT\DEIS\Ch_4\S 4.doc 4-33 Chapter 4.0 Affected Environment corridor were loaded in the proportion observed in the ARTS information. If the dispersion was uniform across a corridor, the flight tracks were loaded uniformly. If the dispersion was non-uniform, the tracks were loaded non-uniformly in the proportions observed in the ARTS information. Flight tracks for the existing 1998 condition are presented in Figure 4.2.5-1. 4.2.5.4 Existing (1998) Aircraft Noise Existinq (1998) Aircraft Noise Contours - Figure 4.2.5-2 presents the 1998 Existing Condition, base case noise contours as developed from the information contained in Section 4.2.5.3. Noise contours were developed in DNL intervals of 65, 70, and 75 dBA. The noise exposure estimates identified for the Existing Condition 1998 noise contours by analysis of land areas and activities within the contours are discussed in Section 4.2.5.5. Comparison of Modeled and Measured DNL - The exposure from aircraft noise can be calculated at specific points when it is desired to better understand the noise environment around PTIA and to evaluate noise levels at specific noise sensitive locations. The measurement locations were selected to represent major noise-sensitive residential areas in close proximity to the airport and that could be potentially located within the 65 DNL noise contour area. For the purposes of the 1998 Existing Condition base case noise contours noise levels were calculated at the six measurement locations. The measurement locations are identified in Appendix B. Additional noise-sensitive specific points were selected for modeling for the future alternative noise contours based on the extent of the DNL 65 dB contours for each alternative. The modeled noise levels and the measured noise levels at the measurement locations are presented in Table 4.2.5-4. Table 4.2.5-4 also presents a comparison of the measured and modeled levels at the six measurement locations. The table shows that modeled noise levels are within 2 dB of measured noise levels except at Sites 4 and 5. Agreement within 2 dB is good correlation. Sites 4 and 5, while in a major residential area that may be impacted by the proposed parallel runway, are not currently located under or near major flight corridors. Therefore, existing levels of aircraft activity would be expected to be low. Measured noise levels would be generated primarily by community activities. Aircraft overflights at Sites 4 and 5 were observed during the monitoring process, nonetheless, the frequency of flights was significantly lower than at other sites. 4.2.5.5 Noise Exposure Noise Exposure Summary - The noise exposures are presented as land areas, activities and populations exposed to various levels of aircraft noise.

The land use areas are presented in Tables 4.2.5-5 and 4.2.5-6. Population and housing exposure estimates are presented in Table 4.2.5-7. The table provides the number of residential units and the population estimates for the areas where aircraft noise exposure is estimated to be DNL 65 dBA or greater. For the 1998 Existing Condition, there are approximately 124 residential dwellings with a population of 290 persons within the 1998 DNL 65 dBA Noise Contour for PTIA. 4.3 PHYSICAL ENVIRONMENT 4.3.1 GEOGRAPHIC OVERVIEW PTIA is located in Guilford County, an agricultural, industrial, and urbanized county in north central North Carolina. Adjacent counties include Alamance County to the east, Rockingham County to the north, Forsyth County to the west, and Randolph County to the south. Guilford County is in the Piedmont physiographic area and is located on a plateau that ranges in elevation from 600 feet to 1,000 feet. PTIA is. at elevation 926 feet mean sea level (MSL). The landform is generally undulating with somewhat hilly slopes along the drainageways with the Appalachian Mountains just to the west. The City of Greensboro, approximately 65 miles east of Raleigh, is the county seat and is at the geographic center of the county. PTIA is surrounded by various land uses. Commercial and industrial land uses abut three sides of the airport's property (east, south, and west of the airport). Single-family and multi-family residential communities are located north of the airport property. Major roadway corridors provide access to the airport. These include Interstate 40 (to the south), State Road 68 (to the west), and Bryan Boulevard (aligned from the southwest portion of the airport's property through the northeast portion of the airport's property). See Section 4.2.1 for details. 4.3.2 CLIMATE Guilford County has a warm, humid climate. The mountains to the west of the county modify both temperature and precipitation. The average annual temperature in Guilford County is 57.8 degrees Fahrenheit (°F). The mean daily maximum temperature occurs in July at 87.4°F and the mean daily minimum temperature occurs in January at 27.8°F. The average winter (December, January, and February) temperature is 39.5°F, and the average summer (June, July, and August) temperature is 75.6°F. Of the total annual precipitation of 42.62 inches, 22 inches typically falls during the period between April and September. Approximately 47 thunderstorms occur during the year, 29 of which occur in summer. Every few years in late summer or autumn, a tropical storm moving inland from the Atlantic Ocean causes extremely heavy rain. The average relative humidity in midafternoon is about 55 percent. Throughout the year, winds are usually in a southwesterly direction. The median monthly wind speed is highest (9 miles per hour) in March. Average seasonal snowfall is 11 inches, and every few years heavy snow covers the ground for a few days to a week. The percentage of possible sunshine is about 64 WAPIEDM0NTDEIS\Ch_4\S_4.doc 4-35 Chapter 4.0 Affected Environment percent in the summer and approximately 54 percent in the winter (Soil Survey of Guilford County, U.S. Soil Conservation Service, 1978). 4.3.3 WATER RESOURCES 4.3.3.1 Surface Water Watershed Hydrology - The Generalized Study Area for the EIS is located within the Cape Fear Watershed, which is the largest of the 17 watersheds in North Carolina, covering approximately 9,149 square miles. The Cape Fear Watershed is one of just four watersheds located entirely within North Carolina. Flow in the Cape Fear Watershed originates in tributaries draining to the Haw and Deep rivers in the North Central Piedmont Region of North Carolina, near Greensboro. The Cape Fear River is formed by the confluence of the Deep and Haw rivers just downstream of the B. Everett Jordan Reservoir Dam. The Cape Fear River flows in a generally southeastern direction until it empties into the Atlantic Ocean at Cape Fear, south of Wilmington. The Cape Fear Watershed is divided into six major hydrologic areas (8-digit hydrologic units) by the U.S. Water Resources Council and the U.S. Geologic Survey (USGS). These include the Haw River/Jordan Reservoir (03030002), Deep River (03030003), Upper Cape Fear (03030004), Lower Cape Fear (03030005), Back River (03030006), and Northeast Cape Fear (03030007) hydrologic areas. The North Carolina Department of Environmental and Natural Resources Division of Water Quality (NCDENR DWQ) further subdivides these six major hydrologic areas into 24 sub-basins denoted by 6-digit numbers (03- 06-01 to 03-06-24). The Generalized Study Area is located in the Piedmont region of the Cape Fear Watershed in the Haw River/Jordan Reservoir (03030002) and Deep River (03030003) hydrologic areas (see Figure 4.3.3-1). Approximately 50.07 square miles of the Generalized Study Area is located in the Haw River/Jordan Reservoir (03030002) hydrologic area within the Reedy Fork Sub-basin (03-06-02). Approximately 27.6 square miles of the Generalized Study Area is located in the Deep River (03030003) hydrologic area within the East and West Fork Deep River Sub-basin (03-06-08). The Reedy Fork Sub-basin (03-06-02) drains the north and southeast sections of the Generalized Study Area, and the Deep River Sub-basin (03-06-08) drains the southwest section of the Generalized Study Area. The topography within the Reedy Fork (03-06-02) and East and West Fork Deep River (03-06-08) sub- basins within the Generalized Study Area is rolling hills with elevations averaging approximately 900 to 940 feet, NGVD. These hills have slopes averaging approximately 2 to 5 percent. The tributaries of the primary streams have longitudinal slopes averaging approximately 2 to 5 percent. The main stem of the primary streams within the Generalized Study Area have flatter longitudinal slopes averaging approximately 0.5 percent. The majority of the primary streams within the Generalized Study Area are in the 100-year floodplain (see Section 4.3.4, Floodplains).

Z c p W The following two sections contain brief descriptions of the hydrologic characteristics of the entire Reedy Fork (03-06-02) and East and West Fork Deep River (03-06-08) sub-basins, respectively. A discussion of the primary streams within the Generalized Study Area and general drainage patterns follows. Table 4.3.3-1 shows the drainage areas within the Generalized Study Area for the primary streams, general land uses, and road crossings for the primary streams. Drainage characteristics within PTIA are discussed in the section, "Drainage Characteristics for PTIA." Reedy Fork Sub-basin (03-06-02) - The Reedy Fork Sub-basin (03-06-02) encompasses approximately 562 square miles and is located within the Haw River/Jordan Reservoir hydrologic unit (03030002). The total area occupied by water in this sub-basin is approximately 7 square miles. Principal waterways include Reedy Fork, North and South Buffalo creeks, Buffalo Creek, Quaker Creek, Stony Creek, and a middle segment of the Haw River. The three drinking water reservoirs for the City of Greensboro are Lake Higgins, Lake Brandt, and Lake Townsend, which are located in the Reedy Fork Sub-basin (03-06- 02). Reedy Fork originates northwest of the City of Greensboro and flows east into the Lake Brandt reservoir. A segment of Reedy Fork, approximately 7,000 feet long, flows from Lake Brandt into the Lake Townsend reservoir. Reedy Fork flows east for approximately 3 miles from Lake Townsend and joins Buffalo Creek and then flows approximately 6 miles from Buffalo Creek to the Haw River near Burlington, North Carolina. South Buffalo Creek originates at the west end of the Reedy Fork Sub-basin (03-06-02) near Greensboro, North Carolina, and flows in an easterly direction through the City of Greensboro. South Buffalo Creek joins North Buffalo Creek, which originates in urban areas in the City of Greensboro, to form Buffalo Creek east of the city limits. Buffalo Creek flows north and joins Reedy Fork at the northeast section of Guilford County. Stony Creek and Quaker Creek originate at the northeast end of the Reedy Fork Sub-basin (03-06-02) in Caswell and Alamance counties, respectively, and flow south to the Haw River in Burlington, North Carolina. The Haw River flows south and joins the Deep River to form the Cape Fear River downstream of the B. Everett Jordan Reservoir Dam in Lee County. Reedy Fork is the principal water body within the EIS Generalized Study Area of the Reedy Fork Sub- basin. Approximately 3 miles of the main stem of the upper reach of Reedy Fork flow through the northwest section of the Generalized Study Area. Reedy Fork flows northeast and discharges into Lake Brandt north of the Generalized Study Area. The other major tributaries within the Generalized Study Area that directly or indirectly join Reedy Creek outside of the Generalized Study Area include: Beaver Creek, Moores Creek, Brush Creek, Horsepen Creek, and head water tributaries of North Buffalo Creek and South Buffalo Creek. The drainage boundaries within the study limits of these major tributaries are shown on Figure 4.3.3-1. Approximately 2.5 miles of the main stem of Beaver Creek flow through the northwest corner of the Generalized Study Area parallel and north of Reedy Fork. Beaver Creek flows northeast and joins Reedy Fork north of the Generalized Study Area near S.R. 68. Moores Creek flows northeast and discharges into Reedy Fork north of the Generalized Study Area just upstream of Pleasant Ridge Road, approximately 1 mile west of Lake Brandt. WAPIEDMONT\DEIS\Ch_4\S_4.doc 4-37 Chapter 4.0 Affected Environment The entire main stem and all tributaries of Brush Creek and Horsepen Creek are within the Generalized Study Area. Brush Creek and Horsepen Creek flow northeast and discharge into Lake Higgins and Lake Brandt at the northeast section of the Generalized Study Area, respectively. Brush Creek is the only stream with its entire drainage area within the Generalized Study Area. Horsepen Creek and Brush Creek receive a large percentage of stormwater runoff from such varied urbanized land uses as PTIA, single- family and multi-family residential, public/institutional, light and heavy industrial, and commercial land uses. Brush Creek and Horsepen Creek are the only primary tributaries in the Reedy Fork Sub-basin (03- 06-02) that drain areas occupied by PTIA. Three tributaries of North Buffalo Creek identified as Tributaries A, B, and C drain the east central boundary of the Generalized Study Area. Tributaries C. and B drain Lake Euphemia and Lake Hamilton, respectively. All three tributaries exit the Generalized Study Area in the vicinity of Hamilton Lakes Park and Starmount Forest Country Club and flow east and join North Buffalo Creek at W. Wendover Avenue (U.S. 421). North Buffalo Creek traverses the City of Greensboro and joins South Buffalo Creek outside of the City of Greensboro city limits to form Buffalo Creek, which flows north to Reedy Fork. Two headwater tributaries of South Buffalo Creek, South Buffalo Creek Tributaries A and C, flow southeast and join south Buffalo Creek at the southeast corner of the Generalized Study Area along Interstate-40. South Buffalo Creek exits the southeast corner of the Generalized Study Area parallel to the westbound lanes of Interstate-40. South Buffalo Creek traverses the southern portion of the City of Greensboro along Interstate-40 in an easterly direction and gradually bends to the north, east of the City of Greensboro city limits, where it joins North Buffalo Creek to form Buffalo Creek. East and West Fork Deep River Sub-basin (03-06-08) - The East and West Fork Deep River Sub-basin (03-06-08) occupies approximately 179 square miles and is located within the Deep River hydrologic area (03030003). The total area occupied by water in the East and West Fork Deep River Sub-basin (03-06- 08) is approximately 2 square miles. Principal waterways include the East and West Fork Deep Rivers and the Deep River. Two drinking water reservoirs for the City of High Point, High Point Lake and Oak Hollow, are located in the East and West Fork Deep River Sub-basin (03-06-08). The East and West Fork Deep rivers originate at the north end of the sub-basin near Greensboro and High Point, North Carolina, respectively. The West Fork Deep River flows south and discharges into Oak Hollow Lake in High Point, North Carolina. The East Fork Deep River flows south and discharges into High Point Lake near Jamestown, North Carolina. The dam at Oak Hollow Lake discharges into the upper reach of the Deep River, which flows through High Point Lake and continues to flow south where it joins the Haw River in Lee County to form the Cape River. The East and West Fork Deep rivers and Bull Run are the three primary tributaries of the Deep River in the East and West Fork Deep River Sub-basin (03-06-08) within the Generalized Study Area. The area draining to the Long Branch Tributary was included in the drainage area for the East Fork Deep River because Long Branch joins the East Fork Deep River immediately south of the Generalized Study Area. The East Fork Deep River is the only primary tributary in the East and West Fork Deep River Sub-basin (03-06-08) that drain areas occupied by PTIA. The East Fork Deep River and Long Branch flow south and join immediately south of the Generalized Study Area, prior to discharging into High Point Lake. The WAPIEDM0NTDEIS\Ch_4\S_4.doc 4-38 Chapter 4.0 Affected Environment drainage basin for the East Fork Deep River has the highest concentration of industrial, commercial, and developed land uses within the Generalized Study Area. Several unnamed tributaries of the West Fork Deep River drain the southeast section of the Generalized Study Area. These tributaries flow west and join the West Fork Deep River immediately west of the Generalized Study Area. The main stem of the West Fork Deep River flows south just west of the Generalized Study Area boundary. The main stem of the West Fork Deep River enters the southeast corner of the Generalized Study Area where it discharges into Oak Hollow Lake. Three tributaries of Bull Run flow south and exit the Generalized Study Area south of Hilltop Road and enter Bull Run just south of the Generalized Study Area. Bull Run flows south and joins the Deep River in Jamestown, North Carolina. Stream Flow Records - The USGS has two stream gauging stations in the vicinity of Generalized Study Area for which discharge records are published. The first station (02093800) is located north of the Generalized Study Area 2 miles east of Oak Ridge Road in Reedy Creek. The second station (02099000) is located in the East Fork Deep River at West Wendover Avenue in the south section of the Generalized Study Area. Table 4.3.3-2 shows a summary of the historical flows for these two stream gauging stations as published in the Water Resources Data North Carolina Water Year 1998. Estimates of stream flow during 10-, 25-, 50-, and 100-year storms for many of the streams within the Generalized Study Area were calculated in the Flood Insurance Studies for the City of Greensboro, Guilford County and the City of High Point (see Table 4.3.4-1 in Section 4.3.4, Floodplains). Drainage Characteristics of PTIA - A Stormwater Master Plan (SWMP) for PTIA is currently being developed. The SWMP will provide guidelines and design criteria for stormwater management associated with current and future land development that may occur within land owned by the PTAA. Approximately 2,838 and 227 acres of PTIA are located within the Reedy Fork (03-06-02) and East and West Fork Deep River (03-06-08) sub-basins, respectively. Approximately 1,507 and 1,331 acres of the airport within the Reedy Fork Sub-basin (03-06-02) drain to Brush Creek and Horsepen Creek, respectively. The northwest section of the airport drains to Brush Creek and is subdivided into 27 drainage sub-basins. The southeast section of the airport drains to Horsepen Creek and is subdivided into 30 drainage sub-basins. All of the 227 acres located in the southwest section of the airport property are within the East and West Fork Deep River sub-basin (03-06-08) and is subdivided into six drainage sub-basins (Baker and Associates, 1999). The drainage basins within the airport are shown in Appendix K. Brush Creek and Horsepen Creek are part of the City of Greensboro water supply watershed and flow into the Lake Higgins and Lake Brandt water supply reservoirs, respectively. The East Fork Deep River is part of the City of High Point water supply watershed and flows into the High Point Lake water supply reservoir. Approximately 404 acres of PTIA are covered by impervious cover, such as runways, roofs, roads, and parking areas. These 404 acres account for approximately 13 percent of the total land area within the W:\PIEDM0NTDEIS\Ch_4\S_4.doc 4-39 Chapter 4.0 Affected Environment PTIA property. Of the total 404 acres, approximately 186, 167, and 51 acres of impervious area drain to Brush Creek, Horsepen Creek, and the East Fork Deep River, respectively (Baker and Associates, 1999). The existing stormwater management system at the airport consists of a combination of open channel and closed storm sewers discharging to Brush Creek, Horsepen Creek, and the East Fork Deep River through approximately 50 outfalls (Baker Associates, 1999). Most of the stormwater runoff from airport discharges directly from these outfalls to receiving water bodies. The PTIA SWMP shows four existing ponds collecting stormwater from developed areas and discharging to Brush Creek and Horsepen Creek. One pond collects stormwater from the Marriott Hotel site and roadways at the airport entrance and discharges into Brush Creek. Three ponds collect stormwater from maintenance hangars at the southeast section of the airport and discharge into Horsepen Creek. Surface Water Quality Classifications and Water Quality Standards - North Carolina has established a water quality classification and standards program pursuant to General Statute (G.S.) 143-214.1. Classifications and standards are developed pursuant to 15A North Carolina Administrative Code (NCAC) 28.0100 - "Procedures for Assignment of Water Quality Standards." Waters were classified for their "best usage" in North Carolina beginning in the early 1950s with classification and water quality standards for all of the state's river basins adopted by 1963. North Carolina water classifications and standards are consistent with the Federal Clean Water Act and its amendments, promote the protection of surface water supply watersheds and high quality waters (HQW), and protect unique and special pristine waters with outstanding resource values. Classifications are assigned to protect uses of the waters such as swimming, aquatic life propagation, or water supplies (Cape Fear River Basin Wide Water Quality Management Plan, October 1996). All fresh surface waters in North Carolina are assigned one of the primary water classifications shown in Table 4.3.3-3 and may also be assigned one or more of the supplemental classifications shown in Table 4.3.3-4. The primary classification for fresh surface waters within the Generalized Study Area draining to the Lake Higgins or Lake Brandt drinking water reservoirs is the water supply classification, WS-III, in the Reedy Fork Sub-basin (03-06-02). The primary classification for fresh surface waters within the Generalized Study Area draining to the Oak Hollow Lake or High Point Lake drinking water reservoirs is the water supply classification, WS-IV, in the East and West Fork Deep River Sub-basin (03-06-08). Freshwaters in the Reedy Fork (03-06-02) and East and West Fork Deep River (03-06-08) sub-basins within the Generalized Study Area draining to water bodies not used for water supply are classified as "C" freshwaters. Fresh surface waters in the Generalized Study Area were assigned the Nutrient Sensitive Water (NSW) supplemental classification or none at all. Freshwaters in the water supply watershed (WS-III) of the Reedy Fork Sub-basin (03-06-02) were the only waters within the Generalized Study Area with the secondary NSW classification. A listing of the fresh surface waters within the Generalized Study Area and their respective primary and supplemental classifications is shown in Table 4.3.3-5. Any unnamed stream within the Generalized Study Area that is not classified carries the same classification as that assigned to the stream segment to which it is a tributary.

W:\PIEDMONTIDEIS\SEC.4\S 4.3\TBLS\T 433-5.doo\03/13/00 Water bodies with the symbol "CA" after their supplemental classifications in Table 4.3.3-5 are in Critical Areas. Critical Areas are adjacent to a water supply intake or reservoir where the risk associated with pollution is greater than from the remaining portions of the watershed. The Critical Area is defined as extending either 0.5 mile from the normal pool elevation of the reservoir where the intake is located or to the ridge line of the watershed (whichever comes first); or 0.5 mile upstream from and draining to the intake (or other appropriate downstream location associated with the water supply) located directly in the stream or river (run-of-the-river), or to the ridge line of the watershed (whichever comes first) (Subchapter 2B - Surface Water and Wetland Standards, Section 0.0202 definitions (20)). Critical Area locations within the Generalized Study Area are shown on Figure 4.3.3-1. The three Critical Areas within the Generalized Study Area are adjacent to Lake Higgins and Lake Brandt, Oak Hollow Lake, and High Point Lake. The Critical Areas adjacent to Lake Higgins and Lake Brandt, Oak Hollow Lake, and High Point Lake occupy approximately 4.30, 3.0, and 0.40 square miles, respectively, within the Generalized Study Area. The Critical Areas consist of four divisions or tiers to manage development within the Critical Area. Explanations of these four tiers and limitations on land use are shown in Table 4.3.3-6. The discharge requirements for water supply (WS) classified waters vary significantly from WS-1 to WS-V, and these are often a reflection of the level of the development within the watershed of a water intake. The WS-1 classification carries the most stringent requirements for discharges and the surrounding land use activities while WS-V carries the least. A WS-1 classification requires a completely undeveloped watershed, and WS-V classified waters are in highly developed watersheds. A summary of the watershed protection rules for water supply watersheds are summarized in Table 4.3.3-7. Specific water quality standards to protect aquatic life and human health for fresh surface waters in North Carolina are shown in Tables K-1 and K-2 in Appendix K. The water quality standards for all classifications of fresh surface waters in North Carolina are the basic standards applicable to Class C waters. Additional and more stringent standards for some of the parameters are applicable to water supply classifications (WS-1, WS-II, WS-III, WS-IV, and WS-V). Water Quality Data - The North Carolina Department of Environment and Natural Resources, Division of Water Quality (NCDENR DWQ) has initiated a whole basin approach to water quality management. Each of the 17 major river basins within the state will be assessed every 5 years and incorporated in the basin- wide management plan. The DWQ uses these plans as a guide to manage and administer its water quality program duties and responsibilities. These plans also provide a framework for cooperative efforts between property owners, local governments, and the general population toward a common goal of protecting the basin's water resources while accommodating reasonable economic growth. During these assessments, a variety of biological, chemical, and physical data are collected and evaluated in one or more of the following seven monitoring programs: • Benthic macro-invertebrate monitoring, • Fish population and tissue monitoring, • Lakes assessment, WAPIEDM0MIDEIS\Ch_4\S_4.d0c 4-41 Chapter 4.0 Affected Environment • Aquatic toxicity monitoring, • Special chemical/physical water quality investigations, • Sediment oxygen demand monitoring, and • Ambient water quality monitoring. The latest Cape Fear River Basin Wide Water Quality Management Plan was approved by the North Carolina Environmental Management Commission in October 1995 and will be updated in 2000. This document provides a summary of existing water quality and causes and sources of water pollution in the portions of the Reedy Fork (03-06-02) and the East and West Fork Deep River (03-06-08) sub-basins within and in close proximity to the Generalized Study Area as reported in the 1995 Cape Fear River Basin Wide Water Quality Management Plan for benthic macro-invertebrate monitoring, lake assessments, aquatic toxicity monitoring, and ambient water quality monitoring. Fish population and tissue monitoring, special chemical/physical water quality investigations, and sediment oxygen demand monitoring were conducted in the Reedy Fork (03-06-02) and the East and West Fork Deep River (03-06- 08) sub-basins but not within the Generalized Study Area or waters outside of the Generalized Study Area that may be impacted. Below are descriptions of the benthic macro-invertebrate monitoring, lake assessments, aquatic toxicity monitoring, and ambient water quality monitoring conducted within the Generalized Study Area and their respective water quality summaries as published in the 1995 Cape Fear River Basin Wide Water Quality Management Plan. Additional benthic macro-invertebrate and ambient water quality data for Horsepen and Brush Creeks collected by then NCDENR DWQ in 1997, but not included in the 1998 Cape Fear River Basin Wide Water Quality Management Plan, are also included. Benthic Macro-invertebrates - Benthic macro-invertebrates, or benthos, are organisms that live in and on the bottom of rivers and streams. Benthos are a reliable water quality indicator because they are relatively immobile and sensitive to subtle changes in water quality. Five bio-classifications; Poor, Fair, Good-Fair, Good, and Excellent are assigned to each benthic sample based on the number of taxa present- E pheme ropte ra, Plecoptera, and Trichoptera (EPT) in pollution-intolerant groups: mayflies, stoneflies and caddisflies (aquatic insect larvae). These three groups are used to develop EPT ratings. Likewise ratings can be assigned a Biotic Index that summarizes tolerance data for all taxa in each collection. The two rankings are given equal weight in final site classification. Higher taxa richness values are associated with better water quality. These bio-classifications primarily reflect the influence of chemical pollutants. Sediment is poorly assessed by taxa richness analysis (NCDENR, April 1995). Table 4.3.3-8 lists all the benthic macro-invertebrate collections by NCDENR within and in close proximity to the Generalized Study Area between 1983 and 1993, giving site location, DEM classification schedule index number, collection date, taxa richness and biotic index values, and bio-classifications (see Figure 4.3.3-2 for sample locations). The Good-Fair bio-classification in Reedy Fork is attributable to its proximity to undeveloped agricultural land. Urban land use was associated with Fair bio-classifications for Horsepen Creek. The East and West Forks of the Deep River are both affected by nonpoint source WAPIEDM0NTDEIS\Ch_4\S_4.doc 4-42 Chapter 4.0 Affected Environment TABLE 4.3.3-6 TIERS WITHIN WATERSHED CRITICAL AREAS Piedmont Triad International Airport Environmental Impact Statement Tier Definition Tier 1 a.

Both streams are within largely agricultural catchments, but have urbanized segments near their headwaters. Comparisons of the East and West Forks of the Deep River indicate greater stress (Fair bio-classification) in the East Fork. The East Fork has about 10 small dischargers near 1-40, mostly associated with oil storage facilities. The NCDNER DWQ sampled three sites in Horsepen Creek and one site in Brush Creek in 1997 for benthic macro-invertebrates that was not reported in the Cape Fear River Basin Wide Water Quality Management Plan (see Figure 4.3.3-2 for sample locations). Benthic sampling followed a modified version of the EPA Rapid Bio-assessment Protocol ll. Table 4.3.3-9 shows the taxa abundance, taxa richness, biotic index values, and bio-classifications for the sites in Horsepen and Brush creeks. Additionally, 10 habitat parameters were evaluated and rated from a scale of 1 to 20. A habitat score is determined by the summation of these 10 parameters. The habitat score indicates if the physical make- up of the channel provides optimal, sub-optimal, marginal, or poor habitat conditions for benthic macroinvertebrates. Table 4.3.3-10 shows the score for the 10 parameters and the overall habitat score for the three sites in Horsepen Creek and one site in Brush Creek. Lakes Assessment - The North Carolina Lakes Assessment Program seeks to protect lakes through monitoring, pollution prevention and control, and restoration activities. Assessments have been made at all publicly accessible lakes, which supply domestic drinking water, and lakes (public and private) where water quality problems have been observed. Data are used to determine the trophic state of each lake. The trophic state is a relative measure of nutrient enrichment and productivity, and whether the designated uses of the lake have been threatened or impaired by pollution (Basin Wide Assessment Report Support Document Cape Fear River Basin, April 1995). The North Carolina Trophic State Index (NCTSI) includes the five following trophic states: (O = oligotrophic, M = mesotrophic, E = eutrophic, H = hypereutrophic, D = dystrophic). A numerical index developed specifically for North Carolina lakes was developed to determine the trophic state of lakes. The NCTSI is based on total phosphorous JP in mg/1) total organic nitrogen (TON in mg/1), Secchi depth (SD in inches), and chlorophyll-a (CHL in ug/1). Lake wide averages of these parameters are mathematically manipulated to produce a NCTSI score for each lake, using equations shown on Table 4.3.3-11. Phytoplankton is a useful indicator of eutrophication because they respond to nutrient availability, light, temperature, pH, salinity, water velocity, and grazing by organisms in higher trophic levels. Prolific growths of phytoplantkton, often due to high concentrations of nutrients, sometimes result in "blooms" in which one or more species of algae may discolor the water or form visible mats on top of the water. Blooms may be unsightly and deleterious to water quality, causing fish kills, anoxia, or taste and odor problems. The Algal Bloom Program was initiated in 1984 to document suspected algal blooms with species identification, quantitative bio-volume, and density estimates. Usually, an algae sample with a bio-volume larger than 5,000 mm3/m3, density greater than 10,000 units/ml, or chlorophyll-a concentration approaching or exceeding 40 ug/I (North Carolina State Standard) constitutes a bloom (Basin Wide Assessment Report Support Document Cape Fear River Basin, April 1995). WAPIEDM0NI\DEIS\Ch_4\S_4.doc 4-43 Chapter 4.0 Affected Environment The five drinking water reservoirs within or in proximity of the Generalized Study Area evaluated in the Lakes Assessment Program were Lake Higgins, Lake Brandt, Lake Townsend, Oak Hollow Lake, and High Point Lake. The trophic state, concentration of parameters to determine trophic state, and algae species and densities for these reservoirs during two or more sample dates are shown in Table 4.3.3-11. All five reservoirs were rated as fully supporting designated uses. However, Oak Hollow Lake was determined to be threatened from excessive algal blooms. Algal blooms and elevated pH values have been documented in Oak Hollow Lake yearly from 1990 through 1993. Small cyanophytes, Anabaenopsis raciborskii, and diatoms, Achnthes minutissima, and other species usually dominated the blooms, which occurred during the summer. The bloom during the summer of 1992 persisted for 7 weeks before subsiding. Several of the sampling events, particularly April of 1991, contained a bloom of Chrysochromulina brevituritta, which has been implicated in taste and odor complaints in the past. During an algal bloom in July 1990, density and bio-volume estimates ranged from 36,684 to 55,200 units/ml and 2,955 to 7,718 mm3/m3. Oak Hollow Lake also has large aquatic macrophyte populations of Ludwigia spp. and Egeria densa (Basin Wide Assessment Report Support Document Cape Fear River Basin, April 1995). Small blue-green algae, often associated with eutrophic waters formed a bloom in High Point Lake in July 1990 and another bloom was reported during the Summer of 1991. Eutrophication concerns, which have been observed in High Point Lake since 1982, suggest a need for continued monitoring as well as a need to protect the contributing watershed from both point and non-point discharges (Basin Wide Assessment Report Support Document Cape Fear River Basin, April 1995). The improved trophic state score measure in 1993 as compared with previous scores for Lake Higgins, Lake Brandt, and High Point Lake may reflect low rainfall recorded in the Cape Fear River Watershed during the growing season of 1993. Low rainfall may have resulted in reduced non-point runoff and associated nutrient contributions to Lake Higgins, Lake Brandt, and High Point Lake. Therefore, an improvement in the trophic status resulted. Aquatic Toxicity Monitoring - Acute and or chronic toxicity tests are used to determine toxicity of discharges to sensitive aquatic species (usually fathered minnows of the water flea, Ceriodaphnia dubia). Results of these tests have been shown by several researchers to be predictive of discharge effects on receiving stream populations. Many facilities are required to monitor whole effluent toxicity by their National Pollutant Discharge Elimination System (NPDES) permits or by administrative letter. Division of Environmental Management's (DEM) Aquatic Toxicology Laboratory may test other facilities. The Aquatic Toxicology Unit maintains a compliance summary for all facilities required to perform tests and provides a monthly update of this information to regional offices and DEM administration. Ambient toxicity tests can be used to evaluate stream water quality relative to other stream sites and or a point source discharge (Basin Wide Assessment Report Support Document Cape Fear River Basin, April 1995). Twenty-three facilities within or near the Generalized Study Area currently monitor effluent toxicity per NPDES permit requirements.

None of the facilities listed in Table K-3 have obtained regulatory relief for toxicity limits through a special or judicial order. Ambient Water Quality Monitoring - The North Carolina Department of Environment and Natural Resources Division of Water Quality maintains a network of ambient water quality monitoring stations in streams, lakes, and estuarine waters throughout North Carolina. There is one active ambient water quality station within the Generalized Study Area in the East Fork Deep River. Several water quality stations are located in each of the drinking water reservoirs: Lake Higgins, Lake Brandt, Lake Townsend, High Point Lake, and Oak Hollow Lake (see Figure 4.3.3-2 for location of sampling sites). The parameters measured at these stations include the following: • Field Parameters - Dissolved oxygen, pH, conductivity, temperature, chlorine. • Nutrients - Total phosphorous, ammonia, total Kjeldahl nitrogen, nitrate+nitrite. • Physical Measurements - Total suspended solids, turbidity, hardness. • Bacterial - Fecal coliforms (Millipore Filter Method). • Metals - Aluminum (no present water quality standard), arsenic, cadmium, chromium, copper, iron, lead, mercury, nickel, silver, zinc. • Water Supply Waters (WS-I, WS-II, WS-III, WS-IV, and WS-V) - Chlorides, total coliforms, manganese, total dissolved solids. • Nutrient Sensitive Waters (NSW) - Chlorophyll-a. Tables K-4 through K-7, in Appendix K, summarize the results of sampling efforts of the ambient water quality monitoring stations in Lake Higgins, Lake Brandt, Lake Townsend, High Point Lake, and the East Fork Deep River by the NCDENR for the months of May through December 1998. The majority of the values for the water quality parameters tested were within state water quality standards as shown in Table K-1. Parameters exceeding water quality standards were noted in bold on Tables K-4 through K-7. The NCDENR DWQ sampled three sites in Horsepen Creek and one site in Brush Creek in 1997 for ambient water quality data not reported in the Cape Fear River Basin Wide Water Quality Management Plan (see Figure 4.3.3-1 for sample locations). Table K-8 in Appendix K shows the values of measured parameters for sites in Horsepen and Brush creeks. All values were within state water quality standards. Use Support Ratings - The use support of a water body is how well a water body supports its designated uses. Determining the use support is another important method of interpreting water quality data and assessing water quality. Surface waters are rated as either fully supporting (S), support-threatened (ST), partially supporting (PS), or non-supporting (NS). The terms refer to whether the classified uses of the water (such as water WAPIEDMONIIDEIS\Ch 4\S_4.doc 4-45 Chapter 4.0 Affected Environment supply, aquatic life protection, and swimming) are being fully supported, partially supported, or not supported. The support-threatened category refers to waters classified as good-fair based on water quality data, in contrast to excellent or good, which are considered fully supporting. The non-supporting category refers to waters where no uses are supported. The partially supporting category refers to waters with a mixture of supported and non-supported uses. Streams rated as either partially supporting or non- supporting are considered impaired supplies (Cape Fear River Basin Wide Water Quality Management Plan, October 1996). The most recent use support ratings for waters within the Cape Fear Basin were determined from water quality data from January 1988 through August 1993 and documented in the Cape Fear Basin Wide Water Quality Management Plan. The water quality data included chemical and physical data, biological ratings, toxicity data related to discharging facilities, fish tissue and fish community structure data, and phytoplankton bloom information. The chemical and physical water quality data included dissolved oxygen, temperature, pH, turbidity, fecal coliform bacteria, chlorophyll-a, ammonia, arsenic, cadmium, chromium, copper, lead, nickel, mercury, zinc, chloride, fluoride, and selenium. These data were interpreted from information available through the U.S. Environmental Protection Agency. The program determines water quality standard violations and computes percentages of the values in violation based on applicable North Carolina water quality standards. According to EPA guidance, the use support determinations based on chemical and physical data were made as follows: • Fully Supporting - For any one pollutant, criteria exceeded in <= 10 percent of the measurements. • Partially Supporting - For any one pollutant, criteria exceeded in 11 to 25 percent of the measurements. • Not Supporting - For any one pollutant, criteria exceeded in 25 percent of the measurements. Biological rankings from benthic macro-invertebrate data from 1983 to 1992 were also used to determine the use support. For rankings purposes, stations classified as Poor with regard to biological data are rated not supporting (NS), and stations classified as Fair are rated partially supporting (PS). Stations classified as Good-Fair are rated as support-threatened (ST), and those having a Good to Excellent bio- classification are rated as supporting (S) their designated uses. Stream segments that recovered a discharge from a facility significantly out of compliance with permit limits or failing their whole effluent toxicity tests were rated as support-threatened, unless water quality data indicated otherwise. Table 4.3.3-12 summarizes the use support determinations for freshwater streams and lakes within the Generalized Study Area. The table includes chemical ratings, biological ratings, overall use support ratings, problem parameters, and major sources of pollution.

U) co U) (D 6 in N 0 O z 0 Impaired Surface Waters - Section 303 (d) of the Clean Water Act (CWA) requires states to develop a list of waters not meeting water quality standards or which have impaired uses. Listed water bodies must be prioritized, and a management strategy or total maximum load (TMDL) must subsequently be developed for all listed waters. Water bodies whose use support ratings were not supporting (NS), partially supporting (PS), and support threatened (ST) were considered initial candidates for the 303(d) list. Although support threatened waters currently meet their intended uses, these waters were reviewed to determine if there were sufficient data to determine if they would become impaired in the next 2 years. Fish consumption advisories on specific water bodies are also cause to include the water body on the 303(d) list. Additionally, biologically impaired water bodies without identifiable problem parameters are also on the 303(d) list (NCDENR, North Carolina's 1998 303(d) List, May 15, 1998). Each of the waters on the 303(d) list was ranked as high, medium, or low to prioritize the DWQ's resources. The ranking is based on numerical rankings for each of the following items: classification, use support rating, presence of endangered species, degree of public interest, and probability of success. The numerical sum of these items is used to determine the priority of the impaired water body. A high priority is assigned to waters with an overall rank between 6 and 8. A medium priority is assigned to waters with an overall rank between 3 and 5, and a low priority is assigned to waters with overall ranks below 3. Further explanations on each of these priorities is provided below: • High - Waters rated high are important resources for the State of North Carolina in terms of their human and ecological uses. Typically they are classified as water supplies, harbor Federally endangered species, and are rated as not supporting. These waters will be addressed first within their basin cycles. • Medium - Waters rated medium may be classified for water supply or primary recreational use, may have state endangered or other threatened species, and may be rated as partially or not supporting. • Low - Water rated low generally is classified for aquatic life support and secondary recreation (i.e., Class C waters) and harbors no endangered or threatened species. Other priorities have also been assigned to waters. A monitor priority indicates that the water body is listed based on data older than 5 years, biological monitoring and no problem pollutant has been identified, or biological monitoring that occurred in waters where we now have evidence that the biological criteria should not have been applied. These waters will be resampled before a restorative approach may be developed because more information is required about the cause of impairment. An N/A priority (not applicable) was assigned to waters that will meet their uses based on the current management strategies. For example, a water body impaired by a point source, and the pollutant causing the impairment has been completely removed from the point source (NCDENR, North Carolina's 1998 303(d) List, May 15, 1998). WAPIEDM0NT\DEIS\Ch_4\S_4.doc 4-47 Chapter 4.0 Affected Environment The management strategy to restore water quality is conducted using the following approaches: • TMDL (Total Maximum Daily Load) - A numeric TMDL as currently defined by the EPA will be developed. • MS (Management Strategy) - These water bodies are on the list based on data collected within the 5 years prior to when the use support assessment was completed. A problem pollutant has been identified, but North Carolina cannot develop a numeric TMDL as EPA currently defines it. A management strategy may contain the following elements: further characterization of the causes and sources of impairment, numeric water quality goals other than TMDLs, and best management practices to restore the water. • RES (Resamples) - These water bodies were identified as being impaired based on water quality data that were greater than 5 years old at the time the use support assessment was performed. This water body will be resampled prior to TMDL or management strategy development to ensure the impairment continues to exist. This will enable the Division of Water Quality to focus its limited resources on water shed that are in greatest need of management. • PPI (Problem Parameters Identification) - Available chemical data do not show any parameters in violation of state standards, but biological impairment have been noted within the 5 years prior to use support assessment. These waters will be resampled for chemical and biological data to attempt to determine the potential problem pollutants. TMDLs or management strategies will be developed within two basin cycles of problem parameter identification. • SWMP (Swampy) - This water body is "swampy" and it was assessed using biological monitoring methods that apply to freshwater areas. The water may not actually be impaired. The water body will be re-evaluated when "swamp" criteria are available. Table 4.3.3-13 shows the impaired water bodies within the Generalized Study Area on North Carolina's 1998 303(d) list. The table includes the overall use support rating, pollution sources, management strategy, and priority. Pollution Causes and Sources - Water pollution is caused by a number of substances including sediment, nutrients, bacteria, oxygen demanding wastes, metals, color, and toxic substances. Sources of these pollution-causing substances are divided into point and non-point sources. Point sources are typically piped discharges from wastewater from wastewater treatment plants, large urban stormwater systems (from municipalities with a population greater than 100,000 such as Greensboro, North Carolina), and industrial stormwater systems. Non-point sources can include stormwater runoff from smaller urban areas (population less than 100,000), forestry, mining, agricultural lands, and construction sites. Point Sources - Point source refers to discharges that enter surface waters through a pipe, ditch, or other well-defined points of discharge. These include municipal, industrial, small domestic, and stormwater systems from industrial sites such as PTIA. The primary water quality pollutants associated with point source pollution are oxygen demanding wastes; nutrients; color; and toxic substances including WAPIEDMONrDEIS\Ch_4\S_4.doc 4-48 Chapter 4.0 Affected Environment M T C) C) RT w J m H Q w Q O F- Cl) 0 w N J Q Ir W Z 0 C W L d C'f Q E W 0 o in = C l3 L CL C Cl) W ?p = O?

Point source discharges are not allowed in North Carolina without a permit from the state. Discharge permits are issued under the NPDES program delegated to North Carolina from the EPA. The NPDES permit contains effluent limits for specific pollutants, assigns major or minor status based on the amount of effluent flow, and requires water quality data to be submitted to the NCDENR DWQ monthly. Minimum NPDES monitoring requirements are provided in 15A NCAC 2B.0500 (NCDENR, Cape Fear River Basin Wide Water Quality Management Plan, October 1996). Table 4.3.3-14 lists the point sources within the Generalized Study Area and their respective discharge points, NPDES permit number, and permitted flow. The majority of point sources within the Generalized Study Area are located south of PTIA. Consequently, the East Fork Deep River and Horsepen Creek are impacted the most by point sources (see Figure 4.3.3-2). Major storm sewer discharges from the City of Greensboro are considered point sources because they serve populations greater than 100,000. Therefore, the City of Greensboro is required to develop an urban stormwater program to help control urban stormwater pollution. Non-Point Sources - Non-point source refers to runoff that enters the surface waters through stormwater or snowmelt. Sediment and nutrients are major pollution-causing substances associated with non-point source pollution. Others include fecal coliform bacteria, heavy metals, pesticides, oil and grease, and any other substance that may be washed off the ground or removed from the atmosphere and carried into surface waters (NCDENR, Cape Fear Basin Wide Water Quality Management Plan, October 1996). The land use activities serving as non-point sources in the Generalized Study Area are agriculture, urban land uses, and construction. Runoff from agricultural lands primarily impact surface waters in the rural northwest and southwest sections of the Generalized Study Area. These waters include Beaver Creek, Reedy Fork, Moores Creek, and the West Fork Deep River. Runoff from industrial, commercial, and residential developments and construction sites impact surface waters in the urban eastern and central sections of the Generalized Study Area. These waters include Brush Creek, Horsepen Creek, East Fork Deep River, and South Buffalo Creek. Runoff from agriculture lands includes pesticides, fertilizers, manure, and sediment. Runoff from urbanized areas, as a rule, is more localized but generally more severe than the agricultural runoff. The rate and volume of runoff in urban areas are much greater due both to the high concentration of impervious surfaces and to storm drainage systems that rapidly transport stormwater to nearby surface waters. These drainage systems, including curb and guttered roadways, allow urban pollutants to reach surface waters quickly and with little or no filtering by vegetated areas. These effects are further exacerbated by replacement of small streams and riparian vegetation with pipes. Urban pollutants include lawn care products such as pesticides and fertilizers; automobile-related pollutants such as fuel, lubricants, abraded tire, and brake linings; lawn and household wastes; and fecal coliform bacteria. Piedmont Triad International Airport - Existing stormwater discharges to surface waters from PTIA will be required to comply with provisions of the General Permit No. NCG150000 issued by the NCDENR Division of Environmental Management (Baker and Associates, 1999). The airport has not been issued WAPIEDM0Nl1DEIS\Ch 4\S_4.doc 4-49 Chapter 4.0 Affected Environment this permit because the permitting process is currently ongoing. The airport will discharge stormwater under the NPDES permit upon its issuance by the NCDENR Division of Environmental Management. The current draft permit specifies monitoring and reporting requirements for both quantitative and qualitative assessment of the stormwater discharge and operational inspections of the entire airport facility, including all stormwater systems. The draft permit proposes annual quantitative sampling for the following parameters: total suspended solids, oil and grease, pH, total rainfall, event duration, and total flow (Baker and Associates, 1999). In addition to quantitative analytical monitoring, the draft permit specifies qualitative visual monitoring of each stormwater outfall for the purpose of evaluating the effectiveness of the required Stormwater Pollution Prevention Plan (SWPPP) and assessing new sources of stormwater pollution. Visual monitoring parameters include color, odor, clarity, floating and suspended solids, foam, oil sheen, and other obvious indicators of stormwater pollution (Baker and Associates, 1999). Self inspections of the airport facilities and all stormwater systems are required to be conducted on a semiannual schedule. The inspections and any subsequent maintenance activities performed must be documented, including recording date and time of inspection, individuals making the inspections, and a narrative description of the stormwater control system (Baker and Associates, 1999). Currently, there are approximately 50 stormwater outfalls that exit the PTIA property. Outfalls that are substantially identical may be grouped for sampling purposes to allow sampling of a reduced number of outfalls. Specific outfalls are targeted for combination and collection in a basin to reduce the number of sampling points identified in the pending NPDES permit. The proposed number of outfalls in anticipation of the permit is reduced from 50 to approximately 31 (Baker and Associates, 1999). The locations of these 31 outfalls from the airport are shown in Appendix K. Modifications of the current stormwater management system of the existing airport development is not mandated per the PTAA Stormwater Management Ordinance or the State of North Carolina Administrative Code Section 15 A, Subchapter 2B. However, should the PTAA discover any existing developed areas that pose a potential threat to existing water quality through uncontrolled stormwater discharge, the PTAA will take appropriate action and install stormwater management controls. The PTAA may direct current tenants to provide stormwater management systems for existing facilities as deemed necessary (Baker and Associates, 1999). 4.3.3.2 Groundwater The hydrogeological setting of the Generalized Study Area is defined by the intricate relation between the streams that convey runoff and the regolith fractured crystalline rock aquifer system that stores groundwater and functions as a conduit to route groundwater from recharge areas to discharge areas (Daniel, 1998).

W APIEDMONT\DEIS\SEC-4\S. 4-3\TBLS\T_433.14.doc\01/28/00 consist of the upper regolith and lower regolith (transition zone) zones underlain by a fractured crystalline bedrock. • Upper regolith - Consists of an unsaturated zone underlain by a saturated zone. Collectively, both zones are composed of saprolite, alluvium, and soil. The saturated zone generally contains the organic layers of the surface soil. The upper regolith consists of an unconsolidated or semi-consolidated mixture of clay and fragmental material dominated by saporlite ranging in size from silt to boulders. The regolith provides the bulk of the water storage because of its porosity. Thickness ranges from zero to more than 150 feet (Daniel, 1998). • Lower regolith (Transition zone) - Consists of partially weathered bedrock and lesser amounts of saporolite. Particles range in size from silts and clays to large boulders of unweathered bedrock. The thickness and texture of this zone depend a great deal on the texture and composition of the parent rock. Augers of three wells in Guilford County northwest of Greensboro indicate the transition zone was approximately 15 feet thick. This zone is more permeable than the upper regolith zone because of less advanced weathering (Daniel, 1998). The groundwater system stores water to the extent of its porosity and transmits water from recharge areas to discharge areas. Water enters the groundwater system in recharge areas, which generally include all of the inter-stream land surfaces at elevations above streams and their adjoining floodplains. Streams and floodplains are, under most conditions, discharge areas. After infiltration, water slowly moves downward through the unsaturated zone to the water table (saturated zone). Water moves laterally through the saturated zone, discharging as seepage into streams, lakes, or swamps. Recharge varies from month to month and year to year, depending on amounts of precipitation, seasonal distribution, evaporation, transpiration, land use, and other factors. Recharge/discharge locations are shown on Figure 4.3.3-1. Annually, estimated mean recharge in the Horsepen Creek drainage basin is 6.39 inches or 478 (gal/day)/acre. The median recharge in the Horsepen Creek drainage basin is 394 (gal/day)/acre. Annually, estimated mean recharge in the Reedy Fork drainage basin is 9.33 inches or 696 (gal/day)/acre. The median recharge in the Reedy Fork drainage basin is 612 (gal/day)/acre (Daniel, 1998). Groundwater Quality Classifications and Groundwater Quality Standards - The groundwater classifications assigned to the groundwaters located within the boundaries or under extraterritorial jurisdiction of the State of North Carolina are GA, GSA, and GC groundwaters (see Table 4.3.3-15 for descriptions of these classifications). Groundwater classifications are based on the quality, occurrence, and existing or contemplated best usage of the groundwaters and are assigned statewide except where supplemented or supplanted by specific classifications assignments by major river basins (Section 0.0300 - Assignment of Underground Water classifications, Subchapter 2L - Groundwater Classifications and Standards). WAPIEDMONT\DEIS\Ch_4\S_4.doc 4_51 Chapter 4.0 Affected Environment The best usage, conditions related to best usage and occurrence for GA, GSA, and GC groundwater classifications are shown in Table 4.3.3-15. All groundwaters within the Generalized Study Area are classified as GA. The groundwater quality standards for North Carolina are the maximum allowable concentrations resulting from any discharge of contaminants to the land or waters of the state, which may be tolerated without creating a threat to human health or which would otherwise render the groundwater unsuitable for its intended best usage. The most stringent groundwater quality standards are for GA groundwaters, followed by GSA and GC groundwaters in their respective order. Standards for specific contaminants are specified in Paragraphs (g) and (h) of Subchapter 2L - Groundwater Classification and Standards Section 0.0200 - Groundwater Quality Standards. Groundwater Quality - Groundwater quality throughout the Generalized Study Area is rated "good." Groundwater quality impairment or limitation on the use of groundwater for potable use is caused primarily by natural geo-chemical processes rather than by widespread degradation of water quality by human activities. Groundwater contamination induced by human activities generally is localized and associated with chemical spills, waste disposal, septic tanks, landfills, oil and gas brine pits, underground storage tanks, aboveground storage tanks, land application or treatment, agricultural activities, and injection wells. Sites of known or suspected contaminant releases within the Generalized Study Area are placed on the Pollution Incidents List by the Guilford County Department of Environmental Health and reported to NCDENR. The purpose of the Pollution Incidents List is to provide a mechanism for reporting, remediation, and documentation. Specific sites within the Generalized Study Area on the Pollution Incidents List are discussed in Section 4.3.7, Hazardous Materials. The U.S. Geological Survey (USGS) and NCDENR monitor groundwater quality in 100 observation wells throughout the State of North of Carolina. However, there are no observation wells within the Generalized Study Area or Guilford County. The nearest USGS/NCDENR observation wells are located west of Guilford County in Davie and Rowan counties. The Guilford County Department of Environmental Health does not maintain a database on groundwater quality parameters other than what is documented on well permits and the Pollution Incidents List. 4.3.3.3 Water Supply Water supply within the Generalized Study Area including PTIA is provided by surface water sources managed and operated by the City of Greensboro and the City of High Point. The City of Greensboro supplies water from Lake Higgins, Lake Brandt, and Lake Townsend to portions of the Generalized Study Area in the City of Greensboro and unincorporated areas of Guilford County. The City of High Point supplies water from Oak Hollow Lake and High Point Lake to portions of the Generalized Study Area in the City of High Point. Lake Higgins is fed by Brush Creek and encompasses approximately 280 acres. The lake was built in 1957 and holds approximately 0.8 billion gallons of water and is utilized as an emergency supply for WAPIEDM0MIDEIS\Ch_4\S_4.doc 4-52 Chapter 4.0 Affected Environment Ln T Cl) m le w J m H CO) Z O Q V zo- Cl) Q J U cc w Q D Z n O V Q Z J O Q H cc O Z r- 0 C. a C r+ c ar C R L C O a) IL C d d r?+ Cl) V R a c c O C W OJ"O c fV Co C co N N =3 d c co o 0 c0 a) W z n CO co i i o d U C) U a c a c C) C) Z O L O 0 N - O N - >, O CO a) C6 N 0 (1) D O -0O ?-2 76 E2 'D c -a (1) 0 > = 5' r C.) 0 c ca U) - D U) ?C7 O U c -0 -C (n 7 D W Crj O L 7 a) L a co cc$ _ Q c CU •- co N ` N c O N L cV .
