Pisgah WWTP From: Toya Fields <toya.fields@ncmail.net> Date: Fri, 13 Oct 2006 14:13:07 -0400 To: Hannah Stallings <Hannah.StallingsC ncmail.net> Hi Hannah: Here are my formal comments. Page 8 of the EA states that the capacity of the facility will be adjusted to 35,000 gpd to accommodate maximum daily flow projections. However it is unclear whether the facility will also be requesting an increase of their permitted flow. The NPDES permit currently contains a 30,000 gpd monthly average flow limit. Since the capacity adjustment is to accommodate peak daily flows, it would be allowed under the current NPDES permit. In this case, the NPDES unit would have no comments. However if the facility plans to request an increase in permitted flow, a permit modification request (including flow justification and supporting documentation) would be required. Thanks Toya Hannah Stallings wrote: Toya - they are going from 30,000 to 35,000 - look on page 8. do you need to formalize up a comment based on this - the "at least 35,000 gpd"? let me know. i'll come by today and grad and region's sign off. thanks. hannah Toya Fields wrote: Hi Hannah, I reviewed the EA. Your cover memo indicates that they are planning on replacing and expanding the WWTP. However I couldn't find any mention in the EA of whether or not they are actually planning on increasing the capacity of this facility. That would be my only comment. If you have any questions, let me know. Also, somehow the region's sign -off was forwarded to Susan. I have it if you need it.

Pisgah Environmental Assessment Blue Ridge Parkway Buncombe County, North Carolina Summary The Mt. Pisgah Wastewater Treatment Plant, which is owned and operated by the National Park Service, is out of compliance with State of North Carolina environmental regulations. This has resulted in a notice of violation from the state, and a need for improvements at the facility. In addition to considering the alternative of no action, the National Park Service evaluated two action alternatives to bring wastewater management into compliance: Construction of a new extended aeration package plant, with discharge to Flat Laurel Creek. Upgrading the existing facility, with discharge to Flat Laurel Creek. Unlike the No Action Alternative, both action alternatives would ensure adequate treatment of current and projected future flows of wastewater from the Mt. Pisgah Wastewater Treatment Plant. This would result in moderate, beneficial, long-term impacts to water quality.

Pisgah Wastewater Treatment Plant Site (Source: North Carolina Heritage Program 20o6; US Fish and Wildlife service 20o6)......................................... 62 PMN PURPOSE AND NEED PURPOSE OF AND NEED FOR THE PROPOSED ACTION Purpose The National Park Service (NPS) is considering replacing the existing wastewater treatment plant (WWTP) on Mt. Pisgah, North Carolina. Mount Pisgah is located near mile 408 of the Blue Ridge Parkway, approximately 20 miles south of Asheville, NC (see Figure i, Site Location Map). The existing wastewater treatment plant provides treatment services for the Mt. Pisgah Developed Area, which includes the Mt. Pisgah Inn (51 units), expanded restaurant, the improved country store, a multi -unit employee housing area, a 140-site campground, a So -site picnic area, and a recreational vehicle waste disposal facility (Figure 2). The plant is owned, operated, and maintained by the National Park Service. The existing wastewater treatment plant near the Mt. Pisgah Developed Area has historically met all North Carolina National Pollutant Discharge Elimination System (NPDES) discharge limits with the exception of ammonia toxicity. Flows are expected to increase in the next several years as the number of visitors coming to the area increases, with a potential for continued and increased numbers of violations of the ammonia toxicity test. The purpose of the proposed project is to provide improved wastewater treatment facilities that will allow the plant to consistently pass the �►, ammonia toxicity test and to have the needed ability to accommodate projected future flows. Need �"�► The current WWTP was constructed in the 195o's and has been modified several times since its original construction. These modifications were necessary to keep up with the increased volume of sewage flow as a result of increased area visitation and new state/federal regulations. The current system is antiquated with rapidly deteriorating infrastructure. During the last three years, the Mt. Pisgah treatment plant has violated the effluent discharge requirements of its National Pollutant Discharge Elimination System permit for ammonia toxicity (the Whole Effluent Toxicity test). As a result, the Blue Ridge Parkway received several Notices of Violation from the North Carolina Department of Environmental and Natural Resources Division. The amount of wastewater treated at the wastewater treatment plant varies seasonally in response to recreational usage of the campground/developed area. During the period May — October when visitor use is at its peak, the wastewater treatment plant receives ,A� approximately 20,000 gallons per day on average, with typical peak flows of 30,000 gallons per day. A flow of 35,000 gallons per day was reported on July 4, 2005 (Veltmann 2005). The plant is closed from November to April when all the facilities in the Mt. Pisgah 1491� Developed Area are closed. During the developed area's off-season, the wastewater ,�•, treatment plant is completely shut down. For a number of years, the wastewater treatment plant effectively treated incoming wastewater flows. However, as the popularity of the Mt. Pisgah area increased, it was accompanied by an increase in wastewater flow to the wastewater treatment plant. -7- Oa, During periods of peak use, the lagoon has to be drawn down, resulting in the periodic violations of the ammonia toxicity test. Bioassay tests for ammonia toxicity were conducted by HDR (in Veltmann Zoos) Olver Incorporated (Olver 2005) reviewed the test reports completed by HDR (Appendix A) for the Pisgah facility and concluded that "the effluent toxicity failures are most likely the result of pH induced ammonia toxicity. Failures have occurred when the wastewater pH has been elevated (around 8) and the toxicity of ammonia is higher. The reported EC20 for Ceriodaphnia dubia, the test species used for toxicity testing, is 15.6 mg/L at a pH of 8.0, and this would suggest that observed ammonia concentrations (> io mg/L) are sufficient to cause toxicity. The periodic rise in wastewater pH is probably the result of algae activity. Photosynthesis carried out by the algae will consume alkalinity and cause a rise in wastewater pH." The NPDES permit does not specify a limit for ammonia, but the plant has been required to conduct Whole Effluent Toxicity Testing in the last two years. In August 2004, the plant received an effluent chronic toxicity violation for failing the Whole Effluent Toxicity test for ammonia. No ammonia toxicity violations occurred in 2005 (NPS 20o6b). The plant has consistently met all other requirements of the state permit, however. Nevertheless, the plant is aging, and requires a significant amount of maintenance during operations to keep it running efficiently and within the limits of the discharge permit. Flows are also expected to increase in the future, as the number of visitors to the area increase over time. The increased wastewater volumes being treated at the Mt. Pisgah Wastewater Treatment Plant, coupled with periodic violations of the ammonia toxicity tests, demonstrated the need for a wastewater management solution. The state discharge permit also requires that the temperature above and below the point of discharge in Flat Laurel Creek not vary more than % degree centigrade. The objective of this requirement is to protect aquatic life in Flat Laurel Creek and Pisgah Creek, into which Flat Laurel Creek flows. Pisgah Creek is a designated state trout water (NCWRC 20o6). To date, the temperature requirement for the discharge has been met. Improved, more efficient facilities are needed to help assure that will continue to be the case. Based on the problems associated with the existing treatment plant, the preferred alternative will meet the following objectives: Provide capacity of at least 35,000 gallons per day to accommodate future maximum daily flow projections. Meet all state of North Carolina regulations, including the ammonia toxicity test and the requirement for temperature variation above and below the discharge point in Flat Laurel Creek. Be capable of handling flow volumes that vary widely over a 12-month period. This environmental assessment analyzes conditions at the site of the existing wastewater treatment plant, describes available alternatives, and assesses the effects of each alternative on the environment. The environmental assessment has been prepared in accordance with the National Environmental Policy Act of 1969 and implementing regulations, 40 Code of Federal WE Regulations Parts 1500-15o8; National Park Service Director's Order #I2 and Handbook, Conservation Planning, Environmental Impact Analysis, and Decision -making; and Section io6 of the National Historic Preservation Act of 1966 as amended, and implementing regulations, 36 Code of Federal Regulations Part 800. PURPOSE AND SIGNIFICANCE OF THE PARK The Blue Ridge Parkway connects the Shenandoah National Park in Virginia with the Great Smoky Mountains National Park in North Carolina via a 469 mile scenic road. The Blue Ridge Parkway is ranked as "America's most scenic drive" by leading travel writers (National Park Service, 2003). This sanctuary of high places encompasses a world of mountain forests, wildlife, and wildflowers thousands of feet above a patchwork of villages, fields, and farms. The toll -free parkway combines awesome natural beauty with the pioneer history of gristmills, weathered cabins, and split rail fences to create our country's most popular national park area. The National Park Service recently reported that annual recreational visitation rose from 16.9 million in 19go to i9.2 million in 2000 (National Park Service, 20o4c). oat%, -9- As, ASHEVILLE - 2nen • �5 SKYLAND 64 Blltn4o e -estat•3Q J 26 9 191 74 To Spartaribwy, 40 rth Caro l 26• S.C.

Under the provisions of the Organic Act that created the National Park Service, approved August 25,1916 (39 Stat. 535), the intended purpose of the Blue Ridge Parkway is to conserve, interpret, and exhibit the unique natural and cultural resources of the central and southern Appalachian Mountains, as well as provide for leisure motor travel through a variety of environments. The general interpretation of the Blue Ridge Parkway's purpose has been refined into the following more specific purpose statements (National Park Service, undated). Physically connect Shenandoah and Great Smoky Mountains National Parks by way of a `national rural parkway' - a recreational destination -oriented motor road traveling through a variety of scenic ridge, mountainside and pastoral farm landscapes. Manage the scenic, natural and cultural resources of the Blue Ridge Parkway's designed and natural areas to preserve the integrity of resources and to provide a quality visitor experience. Influence the protection of the scenic, natural and cultural resources within the corridor composed of those lands that are visible from the Blue Ridge Parkway and/or situated adjacent to the boundary. Conserve and provide for the enjoyment and understanding of the natural resources and cultural heritage of the central and southern Appalachian Mountains. Provide opportunities for visitors to experience the scenic qualities, recreational uses and natural and cultural resources of the Blue Ridge Parkway and its corridor. The route of the Blue Ridge Parkway follows mountain and valley landscapes to link Shenandoah and Great Smoky Mountains National Parks. Its location was selected to provide the best in a variety of scenic, historic, and natural features that evoke the -12- too, /42h1 �1 regional image of the central and southern Appalachian Mountains. In order to maximize scenic views and give Blue Ridge Parkway visitors the impression that they are in a park with boundaries to the horizon, the Blue Ridge Parkway was located in mountainous terrain that normal roads would have avoided. The Blue Ridge Parkway was the first national rural parkway and is widely recognized as an international example �► of landscape and engineering design achievements with a roadway that lies easily on the land and blends into the existing scene. The Blue Ridge Parkway also was the first national rural parkway to be conceived, designed, and constructed as a leisure -type driving experience. The Blue Ridge Parkway follows the crests and ridges of the Blue Ridge, Black, Great Craggy, Great Balsam and Plott Balsam Mountains. These five major mountain ranges are part of the central and southern Appalachian Mountains. The 469 mile parkway encompasses several geographic and vegetative zones, with altitudes ranging from approximately 650 feet at the James River in Virginia to nearly 6,050 feet at Richland Balsam in North Carolina. The Blue Ridge Parkway is known for spectacular mountain and valley vistas, quiet pastoral scenes, sparkling waterfalls, colorful flowers and foliage displays, and interpretation of mountain history and culture. Its varied topography and numerous vista points offer easy public access to spectacular views of southern Appalachian rural landscapes and forested mountains. Designed for recreational driving, the Blue Ridge Parkway provides visitors with quiet, leisure travel, free from commercial traffic and the congestion of high-speed highways. As its All -American Road status indicates, it is one of the most diverse and high quality recreational driving experiences in the world. The park's uninterrupted corridor facilitates the protection of a diverse range of flora and fauna including rare and endangered plant and animal species and areas designated /.a, as national natural landmarks. The park preserves and displays cultural landscapes and historic architecture characteristic of the central and southern Appalachian highlands. 00q PROJECT BACKGROUND 14%� The layout of the facilities on the existing wastewater treatment plan site is shown in Figure a. The plant treats domestic sewage and other wastewater produced by facilities at the Mt. Pisgah Developed Area. The site consists of a five -acre fenced -in area located on a small knoll at the end of a paved access road that connects to the first parking lot on the Blue Ridge Parkway above the plant. The site is located at an elevation of approximately 4,600 feet, approximately % mile downslope of the Blue Ridge Parkway parking lot. The upslope and downslope areas adjacent to the plant are occupied by relatively mature hardwood forests of Mt. Pisgah. Flat Laurel Creek is located approximately a few ,,,N hundred feet downslope of the site and connects ultimately to Pisgah Creek, a tributary of the East Fork of the Pigeon River (Figure 4). -13- , 'l�// \ ;'\ \'�' Flat Laurel Creek 'f Pisgah Creek \ f� Btu, Bafd /i: Blue Ridge Parkway j/ Wastewater Treatment Site Mt.

PISGAH WASTEWATER TREATMENT PLANT. -14- Al Except for a narrowly defined seepage slope emergent wetland/intermittent stream located just inside the main gate of the facility between the fence and the main plant road, the site is completely cleared of all natural vegetation and is maintained as a wastewater treatment plant facility. The existing facilities include a wastewater influent pipeline that enters the site from the east, next to the main gate, a 0.46 acre, three - compartment aerated lagoon, a lagoon effluent transfer station, a lobe tank, two effluent transfer (submersible type) pump units, filters, and chlorination and dechlorination ,.� units. An abandoned sludge drying bed and Imhoff tank are also located on the east side of the site just inside the entry gate. Treated effluent is discharged through a 4-inch pipe down a seasonally dry channel and into Flat Laurel Creek downslope of the plant. The wastewater treatment process includes the following steps. Plant influent is conveyed via gravity flow to a 0.46 acre, three -compartment aerated lagoon. The ,0� wastewater is pumped from the lagoon effluent transfer station to a lobe tank. Two existing effluent transfer (submersible type) pump units are used for this purpose. Wastewater is pumped through filters, then is chlorinated and de -chlorinated before being discharged to an unnamed tributary of Pisgah Creek. A diaphragm pump is located in a separate concrete chamber for pumping settled sludge out of the lagoon. A general management plan was initiated in 2002 to establish and guide the overall management, development, and use of the Blue Ridge Parkway in ways that best suit visitors while preserving the park's cultural and natural resources. The objective of the /OW►, general management plan is to support the purpose for which the park was established and to formalize the park's future direction. A preliminary engineering feasibility study of potential wastewater treatment alternatives for the Mt. Pisgah facilities was completed by J.F. New & Associates in August, 200i Q.F. New & Associates, 2001). This study focused on plant capabilities and deficiencies and made recommendations to improve plant operations. A Value Design Analysis was conducted in 2003 to evaluate the proposed alternative wastewater treatment plant modifications. The final product of this analysis was a Value Design Analysis Report, which included an outline of specifications, site design documents at a level of completion equivalent to 40 percent complete construction documents, and cost estimates (National Park Service, 2003). The major conclusions of the assessment were as follows (as summarized from Veltman 2005): Effluent toxicity failures have probably been caused by ammonia toxicity. The proposed wetland treatment area was at least twice the area proposed by J. F. New & Associates. The proposed site was said to be of inadequate size to support a wetlands treatment system for the Mt. Pisgah facilities. Construction of a proposed terraced wetland system on the site of the present wastewater lagoon was said to be impractical because it cannot occur until the ee1 wetlands have developed. (AINk It was proposed that a wetlands treatment system be ruled out. 491� Following the initial engineering assessments, an additional assessment regarding the feasibility of wetland treatment systems was prepared by Olver, Inc. (Veltman2005). This report concluded the following: -15- The use of a wetland treatment system was discouraged, and a more conservative approach was recommended instead. Upgrade of the existing treatment facilities was identified as a practical option and it was recommended that this option be explored in more detail. It was also suggested that a more conservative system could be "accompanied by the addition of several wetland treatment units to improve both nitrification and denitrification." Additional alternatives to upgrading the existing system, including package plants, were also proposed. These systems would take up less space than the existing system and would improve the visual appearance of the site. The assessment also concluded..."If desired, effluent from these alternative processes could be used to feed a series of small vegetated wetlands beds. The use of media filters, MBRs [Membrane Bioreactors] , and SBRs [Sequencing Batch Reactors] should be explored further." Other projects related to the proposed wastewater treatment system that have been completed include an Environmental Assessment and Finding of No Significant Impact for the Rehabilitation of the Mt. Pisgah Utilities in October 2003 (National Park Service, 2003). The focus of this document was on the upgrade of the supporting infrastructure for the existing wastewater treatment system, including replacement of the leaking water and sewer collection systems in the Mt. Pisgah developed area. The Environmental Assessment also included a partial study of the existing wastewater treatment plant area. All of the information collected to date was then used by the National Park Service in the fall of 2005 to conduct a Value Analysis and Choosing by Advantage importance process workshop. The objective of the workshop was to determine the most ideal and preferred wastewater treatment plant facility for the Mt. Pisgah area. The product of this effort was summarized in a Value Analysis Report — Mini Value Analysis (NPS 20o6f)(Appendix A). SCOPING The Council on Environmental Quality (CEQ 1978) guidelines for implementing the National Environmental Policy Act and the National Park Service National Environmental Policy Act guidelines contained in Director's Order # 12: Conservation Planning, Environmental Impact Analysis and Decision Making Handbook (National Park Service, 2ooib) require scoping. Scoping is an early and open process completed by the National Park Service to: Determine important issues. Eliminate issues that are not important or relevant. Identify relationships to other planning efforts or documents. Define a time schedule of document preparation and decision -making. Define purpose and need, agency objectives and constraints, and the range of alternatives. There are two types of scoping — internal and external. Internal scoping is conducted by the National Park Service to determine the types of issues that might be associated with a -16- �1 proposed project, and forms the basis for the assessment of the effects of the alternatives. Internal scoping involves analyzing the characteristics of construction and operation, and relating these proposed actions to potential environmental effects. External scoping involves early public involvement and can include letters to involved agencies, stakeholder meetings, informal public meetings or open houses, formal public hearings, MON and newsletters. Scoping letters to the agencies are required for every environmental assessment prepared by the National Park Service. The other forms of external scoping are used in varying degree, depending on the nature of the issues involved for a articular project. The amount of external scoping is determined primarily b the degree P P j P� g P� Y Y g AMIN of the potential for adverse environmental effects of a proposed project. The National Park Service has conducted the following scoping activities in conjunction with the proposed wastewater treatment facilities at Mt. Pisgah: An internal scoping meeting was held on November g, aoo5 at the Blue Ridge Parkway Headquarters at Hemphill Knob to discuss the potential issues surrounding alternatives for construction and operation of a new wastewater treatment plant. It was determined that primarily due to space and topographic �► limitations, none of the alternatives that involved wetland treatment would be employed, and that all construction activities for the proposed project would take place entirely within the existing disturbed fenced -in area occupied by the existing treatment plant and lagoon. Therefore, the nature of the potential effects of the proposed project on the environment would be limited. External scoping has included the following: Coordination letters to federal, state and local agencies, including the US Environmental Protection Agency, North Carolina Department of Environmental and Natural Resources, the US Fish and Wildlife Service, and the State Historic Preservation Officer were circulated in April, 2oob. Preparation and distribution of a newsletter that summarizes the purpose and need of the project and alternatives. The newsletter was posted on the park website and was also mailed to stakeholders. A copy of the draft environmental assessment was distributed to the review agencies. The draft environmental assessment will be made available to the public at the park website and at park headquarters. For the previous environmental assessment entitled Environmental Assessment and Finding of No Significant Impact (FONSI) for the Rehabilitation of the Mt. Pisgah Utilities in October 2003 (National Park r� Service, aoo3), the National Park Service invited stakeholder groups and the public to open meetings to inform the public and identify potential concerns. This project included a brief discussion of the proposed changes in the wastewater treatment plant itself, and a detailed assessment of the effects of infrastructure improvements (including roads and pipelines). Together, all of these scoping activities assure that potential issues and concerns associated with the construction and operation of the proposed wastewater treatment -17- plant project have been identified and included in this environmental assessment. Because all of the construction activities would occur entirely within the existing plant site, the environmental effects would be limited. ISSUES AND IMPACT TOPICS Potential issues and concerns affecting the proposed action were identified based on the specific design and operational features of each facility. Issues and concerns affecting this proposal were identified from past National Park Service planning efforts and by input from Blue Ridge Parkway staff, local, state and federal agencies, local and regional organizations, and the general public. The major issues and concerns include: Potential effects on a small emergent wetland located just inside the access gate of the existing fenced -in wastewater treatment plant site. Potential effects on cultural resources that might exist inside the existing fenced -in wastewater treatment plant site. Potential effects on special status species. Potential effects of soil disturbance or soil erosion resulting from grading and/or filling of the lagoon. Ammonia toxicity issues in the receiving stream below the plant. Potential effects of construction and operation on air quality. Potential spreading of nuisance plant seeds (especially bittersweet, Celastrus orbiculatus) in fill dirt brought onto the site from other areas, especially if an alternative is selected in which the lagoon is filled. Potential effects of temperature of the discharge on trout in the receiving stream. Resources of concern that could be affected by the range of alternatives are defined in the National Park Service National Environmental Policy Act process as impact topics. For this project, a set of impact topics was identified based on the potential environmental effects of the alternatives. Potential impact topics were identified based on federal laws, regulations, and Executive Orders; aooi National Park Service Management Policies; and National Park Service knowledge of limited or easily impacted resources. A list of impact topics and a summary of relevant regulations or policies related to each impact topic are provided in Table i. Some impact topics were eliminated based on whether they were estimated to have no effect or a negligible effect on the environment. The rationale for the elimination of selected impact topics is summarized in the section that follows. -18- Table i.

For this reason, this impact topic was retained. Aquatic Resources: Construction of buildings and associated construction activities could affect water quality and aquatic resources during earthmoving activity and through the increase of impervious surface for parking area, piping and buildings. Pisgah Creek, located downstream of the receiving stream, Flat Laurel Creek, is classified as a trout stream. For this reason, this impact topic was retained. -20- ,1 OWN Special Status Species: There is the potential for the endangered flying squirrel and possibly some protected plant species to occur in the vicinity of the proposed wastewater treatment plant and improvements. Therefore, this topic was retained. Owl Impact Topics Dismissed From Further Analysis Certain potential impact topics were dismissed because these resources would not be affected by the alternatives or the potential for impacts under all alternatives would be negligible and/or minor. These topics are listed below with the reasons they were not addressed. Soils: This impact topic is dismissed because the site is already cleared and all construction activity would involve negligible to minor amounts of soil disturbance under either of the two action alternatives. No adverse effects on soils would result during operation. Approximately 4,500 cubic yards (a total of a about approximately 30 truckloads) of clean fill dirt would be brought into the site to fill the lagoon under Alternative B during construction. However, this would have negligible to minor short-term effect on soils in the area where this material is obtained (the actual location for the fill dirt has not yet been determined). Filling the lagoon with clean fill dirt, however, would pose a potential rsq for soil erosion. Potential effects of soil erosion during construction, however, are addressed in the section on water quality. Air Quality: The 1963 Clean Air Act, as amended (42United States Code 7401 et seq.), requires federal land managers to protect air quality, while the zooi National Park Service Management Policies address the need to analyze air quality during park planning. The proposed wastewater treatment plant is located in Buncombe County, North Carolina, which is currently a designated attainment area. This means that concentrations of criteria pollutants are within standards. Should an action alternative be selected, local air quality would be temporarily affected by dust and vehicle emissions. Hauling material and operating construction equipment would result in increased vehicle emissions. Volatile organic compounds, ozone, carbon monoxide and sulfur dioxide emissions would generally disperse quickly from the construction area. This would last only as long as construction activities occurred and would have a negligible effect on regional pollutant levels. Fugitive dust emissions from construction equipment and vehicle traffic would result in short-term minor increases in airborne particulate concentrations in the area near the project site, depending on soil moisture. These emissions would be temporary, highly localized and would have a negligible effect on regional particulate levels. Best management practices to control dust would be required during construction. In summary, local air quality in the immediate vicinity could be temporarily affected by dust generated from site reconstruction activities and emissions from construction equipment and vehicles. There would also be increased automobile emissions from `�°► vehicles using the site. However, these would range from negligible be minor localized ,..►, effects. For these reasons, air quality is an impact topic that was dismissed in this document. OWN -21 - Socioeconomics: Under either of the two action alternatives, construction of the extended aeration package treatment system could have negligible to minor, short term, local, indirect beneficial effects on the economy of the Mount Pisgah area. The company that is hired to construct the package treatment system could be located in the Mount Pisgah area and some of the materials used to construct the package treatment system could be purchased in the Mount Pisgah area. The workers used to construct the system could be residents of the Mount Pisgah area. The operation of the extended aeration package treatment system would have a no long term, local or regional, direct or indirect beneficial or adverse effect on the economy of the Mount Pisgah area. For these reasons, socioeconomics has been dismissed from further analysis. Transportation: Construction vehicles would have negligible to minor direct, indirect and cumulative effects on regional and local transportation along the route to access the site resulting in traffic impacts to public roads in the area. For these reasons, transportation was dismissed from further analysis. Noise / Soundscape: Noise conditions surrounding the wastewater treatment plant would be expected to change under the proposed action. Natural sounds from birds, frogs and other wildlife are evident at the perimeter of the site, but the site itself is entirely disturbed. The construction of the wastewater treatment plant could cause additional disturbance of the site that could result in further reduction in the natural soundscape. However, all of these effects were estimated to be negligible to minor, local and short-term effects. For these reasons, noise is an impact topic that was dismissed from further analysis. Park Operations: The wastewater treatment plant would be constructed and operated to comply with state and federal requirements. The facility would be necessary, appropriate, and consistent with the conservation of park resources and values. The wastewater treatment plant would improve park operations by providing a facility that meets water quality standards. These would be minor long-term beneficial effects. There would be no adverse effects on park operations. For these reasons, park operations were dismissed from further analysis. Wildlife: No wildlife habitat exists on the site, although it is located within a larger prime wildlife area on top of Mt. Pisgah. Because the existing wastewater treatment plant site has been largely cleared, however, and all construction and operation activities would occur inside the fenced area, construction and operation of the proposed project would have no adverse effects on wildlife. Wetlands: A small seepage slope wetland is located along the roadside within the fence line of the wastewater treatment plant boundary. Construction activities such as roadwork or laying of pipeline could affect this wetland. However, this wetland will be delineated and avoided during all construction activities; therefore, there would be no adverse effects on this resource. Therefore, wetlands were dismissed as an impact topic. Vegetation — Native Plant Communities: The majority of the wastewater treatment plant site has been cleared of native vegetation and is maintained either as grassed areas or space for buildings. Fill dirt placed on the proposed construction site could contain seeds of nuisance vegetation, especially bittersweet, Celastrus orbiculatus. However, - 22 - emkA contractors hauling fill dirt to the site would be required to take clean material from a depth of at least 18 inches. Therefore, the proposed project would not result in the spread of non-native vegetation and there would no adverse effects on native vegetation as a result. Therefore, this impact topic was dismissed from further consideration. ,�►, Ecologically Critical Areas: No congressionally designated natural resources, such as ecologically critical areas, Wilderness, Wild and Scenic Rivers, or other unique natural resources are located within the project site, and therefore, ecologically critical areas was dismissed as an impact topic. Floodplains: No floodplains are located within the project site. For this reason, floodplains were dismissed as an impact topic. Geological Resources: The geologic features in or near the site would not be affected by implementation of the proposed action. For this reason, geological resources were dismissed as an impact topic. Prime or Unique Farmlands: The Farmland Protection Policy Act and the U.S. Department of the Interior require an evaluation of impacts on prime and unique agricultural lands. These lands require certain soil types and water availability. According to the Natural Resources Conservation Service located in Asheville, there are no prime or unique farmlands within or near the area proposed for the wastewater treatment plant. Because these areas do not exist in the proposed project site, this topic was dismissed from further consideration. `o'N Lightscape: Although the wastewater treatment plant would be used at night, minimal e_"', outside lighting would be used. The location of the wastewater treatment plant would 110� result in negligible changes in light characteristics created by lighting. Outdoor lights would, however, be shielded to direct the light downward and reduce upward intrusion. For these reasons, lightscape was dismissed as an impact topic. Cultural Resources: Construction of the wastewater treatment plant would occur in a previously disturbed area. The National Park Service Southeast Archeological Center conducted an assessment regarding Section io6 survey needs and determined that a survey was not required. For these reasons, cultural resources is an impact topic that will be dismissed from further evaluation. Sacred Sites: There are no sacred sites, as defined by Executive Order 13007 near the wastewater treatment plant site or within the construction area. For this reason, sacred sites were dismissed as an impact topic. ,�.►, Visitor Use and Experience / Viewshed: Blue Ridge Parkway visitors expected to use facilities in the Mt. Pisgah area would benefit from improved wastewater treatment services. The location of the wastewater treatment plant would not be altered, and is not in an area that is normally visited. Therefore, the viewshed from the Blue Ridge Parkway would not be affected. For these reasons, the visitor use and experience / viewshed Am� impact topic was dismissed from further analysis. egft� Concessions and Commercial Services: The wastewater treatment plant would not be operated by concession or commercial venture. There would be no vending machines or food service at the wastewater treatment plant. Since there would be no new concessions �` - 23 - W, associated with the wastewater treatment plant, concessions and commercial services was dismissed as an impact topic. Public Health and Safety: The proposed plant would be an improvement over the existing facility and would have no adverse effects on public health and safety. Neither of the two action alternatives would have any adverse direct, indirect or cumulative effects on public health and safety. Public health and safety risks would be under control by the National Park Service and would be managed in compliance with applicable state and federal regulations. -24- �1 ALTERNATIVES INTRODUCTION The National Park Service conducted a Value Analysis and Choosing by Advantages workshop for the project alternatives in the fall of 2005 (National Park Service, 2005). A summary of this workshop's proceedings are provided in Appendix A. Eight action alternatives for the existing plant site were evaluated. These were identified as alternatives A through H (these designations are carried through this environmental assessment for consistency). Six of the eight action alternatives were dismissed from r� further evaluation. These are described in the sections entitled "Other Alternatives Considered but Dismissed." The alternatives carried forward for analysis in this environmental assessment are Alternative B (the preferred alternative), Alternative A (the other action alternative); and Alternative O (the no action alternative). THE NO ACTION ALTERNATIVE (ALTERNATIVE O) Alternative O, the no action alternative, would consist of continuing the present management operations and conditions. Alternative O provides a basis for comparing the environmental consequences of alternative B (Preferred Alternative) and the other alternatives. Should alternative O, no action, be selected, the National Park Service would respond to future needs and conditions associated with the park's objectives without major actions or changes from the present course. The existing wastewater treatment plant for the Mt. Pisgah area has a capacity to treat 30,000 gallons per day of wastewater. Flows range from 15,000 gallons per day on average days during the operating season (April -November) to 30,000 gallons per day on peak weekends during this same period. Wastewater, or influent, enters the plant via gravity flow to a 0.46 acre, three -compartment aerated lagoon. From the lagoon it is pumped to a lobe tank in the lagoon effluent transfer station. There are two existing r� effluent transfer (submersible type) pump units. The wastewater is then pumped through filters, chlorinated, and de -chlorinated before being discharged to Flat Laurel Creek. A diaphragm pump is located in a separate concrete chamber for pumping settled sludge out of the lagoon. No more than two 55 gallons drums of chlorine are stored at the WWTP for operational use. Chlorine is transported to the site by maintenance personnel via government vehicles. It is purchased locally in Asheville. The National Pollutant Discharge Elimination System permit limits for the existing facility are summarized in Table 2 (from Veltman 2005). —25— Table 2. National Pollutant Discharge Elimination System Permit Requirements For The Existing Mt. Pisgah Wastewater Treatment Plant (From Veltman 2005) Parameter Average Maximum Flow (gallons/day) 32,000 Biological oxygen demands (milligrams/liter) 30 45 Total suspended solids (milligrams/liter) 30 45 Ammonia (milligrams/liter) No Limit No Limit Whole Effluent Toxicity biomonitorin excursions (pass/fail) Pass/Fail @ 2 % Pass/Fail @ 2 % Phosphorus (milligrams/liter) No Limit No Limit Fecal Coliform (Most Probable Number) <200 <400 Dissolved Oxygen (milligrams/liter) 1 • 2 1 • 2 H (Standard Units) I I NA 1 6-9 j existing aerated lagoon facility meets National Pollutant Discharge Elimination System effluent requirements on a regular basis except during peak flows in the summer when ammonia levels are high and the lagoon levels drop (NPS, 2005b). On these occasions, effluent ammonia toxicity may occur as indicated by whole effluent toxicity biomonitoring excursions. Excessive sludge accumulation in the lagoons over the operating season is the likely cause of the prior whole effluent toxicity excursions. Maintaining the existing plant is not possible because of the continued risk of ammonia toxicity. In addition, the existing plant cannot improve the effluent quality beyond the existing conditions. The NPDES permit does not have temperature requirements but the State of North Carolina requires that the temperature of the receiving stream does not vary more then degree centigrade above and below the discharge point. This has been maintained during the life of the existing plant. This requirement is designed to protect trout in Pisgah Creek, located several miles downstream of the Mt. Pisgah treatment plant. THE OTHER ACTION ALTERNATIVE (ALTERNATIVE A) Alternative A: Upgrade Existing Aerated Lagoon Facility Alternative A would include upgrading the existing lagoon treatment system at Mt. Pisgah. Lagoon systems similar to the one at Mt. Pisgah are in operation throughout the country and comply with similar effluent standards (30 milligrams per liter biological oxygen demand and total suspended solids). The presence of filters downstream of the lagoon at the Mt. Pisgah facility increases the likelihood of meeting the National Pollutant Discharge Elimination System permit requirements considerably. Without the filters, algae in the effluent can cause total suspended solids violations during spring and summer seasons. — 26 The focus of alternative B is primarily on improving the sludge removal system and solids storage treatment capabilities at the existing plant site. According to the July 8, 2005 �1 Technical Memorandum (Bailey 2005), the likely cause of the previous whole effluent toxicity excursions were the excessive sludge accumulation in the lagoons over the operating season. To facilitate more frequent sludge removal from the lagoon, a diesel - driven pump would be installed on a floating barge. The lagoon sludge pump would �°► convey solids to a 25,000 gallon steel sludge storage tank. A 2.5 horsepower progressing cavity sludge transfer pump would be located next to the storage tank so that at the end of the season, sludge could be transferred to a sludge disposal truck. Many other facility OWN improvements would also be incorporated into this project including: sludge drying bed �► and Imhoff tank demolition, office building improvements, partial plant asphalt drive ,dWA� reconstruction, and a new emergency electrical generator. /01� OTHER ALTERNATIVES CONSIDERED BUT DISMISSED Alternative C: Polishing Constructed Wetlands Addition /Mb" J.F. New and Associates prepared a Preliminary Engineering Study in August 2001 that evaluated a constructed wetlands treatment system to either supplement or replace the existing lagoon system (J.F. New and Associates, 2001). In the Preliminary Engineering Study, it was assumed that the State would issue a more stringent effluent permit in December 20oi and that more stringent effluent ammonia or other nutrients standards would be enforced. However this has not yet occurred. A Technical Memorandums (Bailey 2005; J.F. New & Associates, Inc., 2ooi), an '®' independent report by Olver, Inc. (Veltman 2005) and a Value Analysis Report -Mini VA (NPS 20o6f) were developed to evaluate the feasibility of replacing the aerated lagoon 'AMIN treatment system with a constructed wetlands waste treatment system. The conclusion of these assessments was that this was not a feasible alternative. Such a system has the '`gft' following disadvantages in relation to the Mt. Pisgah site (from NPS 20o6f): 'wl' Based on preliminary sizing requirements of 20 lbs biological oxygen demand/(acre 11!51� day), 3.5 acres to 5.o acres of constructed wetland area would be required to treat the Mt. Pisgah wastewater. This amount of land is not available at the Mt. Pisgah site. Site constraints at the treatment facility site would severely limit construction of any additional wetlands beyond the site limits without considerable earthwork activities and cost. Per discussions with North Carolina Department of Natural Resources and Environment, regulatory approval of a constructed wetland system for the Mt. Pisgah site would be challenging. Vegetation planted in the wetlands would require harvesting in the fall. In a National Park Service technical memorandum dated July 8, 2005 (National Park Service, 2005), it was reported that the only feasible way to integrate a wetland system at Mt. Pisgah would be via a polishing wetland. A polishing wetland system -27- Of 0.3 acres could be located downstream of the existing filters and the aerated lagoon system would remain in service. Under this alternative, plant effluent would flow in and out of the wetland via gravity, so no additional mechanical or electrical components would be required. However, this alternative does not remove any of the existing mechanical system components from service. Alternative D: Install Recirculating Sand Filtration System The National Park Service has had success using recirculating sand filtration systems at other sites. A recirculating sand filtration system would require a minimum 92' by 18' footprint to treat 30,000 gallons per day. Three septic tanks, a recirculating tank, and recirculation pumps would be required for this alternative. Due to the larger area requirements of this alternative, the only feasible sand filter and tank location would be within the aerated lagoon footprint. This option would require a large amount of compacted fill dirt to bring the top of the filter/tank elevations up to existing grade. A concrete containment barrier would also have to be poured around the filter perimeter. Per conversations with a recirculating sand filter manufacturer, the recirculating sand filter can be anticipated to produce biological oxygen demand and total suspended solids effluent quality less than io milligrams per liter. In addition, ammonia reduction is expected to be in the 40 to 50% range. Advantages of the recirculating sand filter system include prior experience with the system at other National Park Service facilities while disadvantages include having a limited filter construction period due to the need to utilize the aerated lagoon area. Alternative E: Install Membrane Bioreactor Package Treatment System A Membrane Bioreactor package system, an innovative alternative in wastewater treatment, is similar in some respects to the extended aeration package treatment facility. The Membrane Bioreactor uses membrane technology to separate mixed liquor suspended solids in the aeration basin from treated effluent rather than a gravity separation clarifier used in typical activated sludge processes. Similar levels of sludge production would be expected from both systems, however. Membrane Bioreactor systems produce superior effluent quality compared to most other wastewater treatment technologies due to the very small membrane pore space through which the effluent passes. This type of system would be expected to achieve biological oxygen demand and total suspended solids concentrations less than 5 milligrams per liter and ammonia concentration less than i milligram per liter. In this scenario, the lagoon would be taken out -of -service and a new plant influent pumping station wet -well with short-term equalization storage would be constructed. Two submersible pumps would be provided in the pumping station. The Membrane Bioreactor package plant would be mounted to a concrete slab on -grade. The exterior dimensions of the pre -fabricated structure would be approximately 50' (length) by 15' (wide) by 15' (height). Within the structure, the following zones would be present: influent holding tank, anoxic basin, aeration basin, and a membrane basin (two cells). The existing chlorination and de -chlorination facilities would be utilized. A - 28 - programmable logic controller (PLC) and process control panel would be provided to control the system and all process components. Advantages of the Membrane Bioreactor system include the superior effluent quality while disadvantages include higher capital and operating costs (compared to an extended aeration facility). Alternative F: Install Membrane Bioreactor Package Treatment System with Ultraviolet (UV) Disinfection This alternative is identical to alternative E, Install Membrane Bioreactor Package Treatment System, except that the existing chlorination/de-chlorination equipment would be taken out -of -service and a new in -line ultraviolet disinfection unit would be installed. The advantages of installing an ultraviolet disinfection system in conjunction with the Membrane Bioreactor system include elimination of chlorine discharge to the environment and elimination of chlorination / de -chlorination chemicals onsite. Disadvantages include higher capital cost associated with purchasing the ultraviolet treatment equipment. ,"WA Alternative G: Install Sequencing Batch Reactor Treatment System ,A, A Sequencing Batch Reactor treatment system would be constructed to replace the Amos existing aerated lagoon. The National Park Service has used Sequencing Batch Reactor technology successfully at other parks. Two concrete basins would be constructed with 'laws minimum dimensions of (Length-Width-Depth)(LWD) W (length) by 14' (width) by i9' (depth). The Sequencing Batch Reactor system requires a minimum sidewater depth of 16'. There is a considerable amount of rock on the project site and it is very likely that rock would be encountered while constructing these basins. The anticipated Sequencing Batch Reactor effluent quality would likely be in the range of 20-15 milligrams per liter biological oxygen demand, a0-IS milligrams per liter total suspended solids, and 5 milligrams per liter ammonia concentration. Therefore, it is anticipated that the existing effluent filters would have to remain in service. Advantages of the Sequencing Batch Reactor system include prior experience with the system at other National Park Service facilities. Disadvantages include excessive sidewater depth requirements and associated higher construction costs, and an effluent quality that would potentially be very similar to the existing aerated lagoon system. Alternative H: Install Orenco Advantex Filtration System Under this alternative, eight, 5,000 gallons per day Orenco Advantex Filtration system modules would replace the existing aerated lagoon. The National Park Service has used this technology successfully at other parks. The filter modules have dimensions of (LWD) W (length) by 8' (width) by 4'(height). The effluent quality would probably be in the range of ao milligrams per liter biological oxygen demand, ao milligrams per liter total suspended solids, and 5-10 milligrams per liter ammonia concentration. Based upon these ranges, it is anticipated that the existing effluent filters would have to remain in service. 1°"► - 29 - ems eCRIN eohl► Advantages of the Orenco system include prior experience with the system at other parks. Disadvantages include the requirement of a proprietary membrane technology for long-term system operation. Replacing the media may cause problems in the future if the filters become unavailable. ALTERNATIVES SUMMARY Table 3 summarizes the features of alternatives O, A and B, the three alternatives that are analyzed in detail in this environmental assessment. Five goals for wastewater management were identified in the "Purpose and Need" section. The ability of alternatives O, A and B to meet each of these goals is summarized in Table 4. As shown in Table 4, either of the action alternatives would effectively meet all of the project goals. The No Action Alternative would not meet any of the goals.

Alternative A. -39- THE PREFERRED ALTERNATIVE (ALTERNATIVE B) Construct Extended Aeration Package Treatment System Pre-engineered, pre -fabricated extended aeration activated sludge wastewater treatment facilities are commonly used for flow ranges similar to those at the Mt. Pisgah plant. These systems apply the same biochemical technologies frequently used in larger facilities, but can be procured in a fully enclosed system designed for smaller flow ranges. If properly operated and maintained, extended aeration package treatment facilities produce acceptable effluent quality, and low levels of biological oxygen demand, total suspended solids and ammonia. The effluent from the package facility can either be conveyed to the existing filters or bypass the existing filters. Under this alternative, the lagoon would be taken out -of -service and filled in with compacted dirt and the useable plant site area would be increased by approximately 0.46 acres. A new plant influent pumping station wet well with short-term equalization storage also would be constructed. Two submersible pumps would be provided in the pumping station. The extended aeration package plant would be mounted to a concrete slab on -grade. The exterior dimensions of the pre -fabricated structure would be approximately 70' (length) by 15' (wide) by 15' (height). Within the structure, the following zones are present: sludge thickening/storage zone, aeration zone, clarifier zone, and a disinfection contact zone (if needed). The sludge thickening/storage zone would temporarily hold biosolids generated in the system until solids are conveyed to a new onsite sludge storage / treatment facility. Sludge would be gravity conveyed to a 25,000 gallon steel sludge storage tank. A 2.5 horsepower progressing cavity sludge transfer pump would be located next to the storage tank, so that sludge could be transferred to a sludge disposal truck. Sludge drying bed and Imhoff tank demolition would also be included under this alternative. To facilitate facility reliability, a new 25 kW generator would also be included on -site. Advantages of the extended aeration package treatment facility would be the relatively low cost, high degree of reliability, and compact footprint. Alternative B would also provide a new treatment facility for relatively the same costs as alternative A (described below). Given the age of the existing system, there would be continued maintenance concerns if alternative A were implemented. Under alternative B. the effluent, or treated wastewater, would be the same quality or slightly better than the existing system. Since extended aeration package plants are a proven wastewater treatment technology, the North Carolina Department of Environment and Natural Resources permitting process should also be simplified. THE ENVIRONMENTALLY PREFERRED ALTERNATIVE The environmentally preferred alternative is the alternative that will best promote the national environmental policy expressed in the National Environmental Policy Act. The environmentally preferred alternative would cause the least damage to the biological and physical environment, and would best protect, preserve, and enhance historical, cultural, and natural resources. —40— Section ioi(b) of the National Environmental Policy Act identifies six criteria to help determine the environmentally preferred alternative. The act directs that federal plans should: Fulfill the responsibilities of each generation as trustee of the environment for ,y succeeding generations. Assure for all Americans safe, healthful, productive, and esthetically and culturally pleasing surroundings. Attain the widest range of beneficial uses of the environment without degradation, risk of health or safety, or other undesirable and unintended consequences. Preserve important historical, cultural, and natural aspects of our national heritage and maintain, wherever possible, an environment which supports diversity and variety of individual choice. Achieve a balance between population and resource use which will permit high standards of living and a wide sharing of life's amenities. Enhance the quality of renewable resources and approach the maximum attainable recycling of depletable resources. Alternatives A and B both meet these goals more effectively than Alternative O, the No Action Alternative. Each of the action alternatives would effectively manage wastewater and protect water quality. In addition, each has environmental advantages compared to the other. Both action alternatives would enable the National Park Service to "Fulfill the responsibilities ... as trustee of the environment." "Safe, healthful,... and esthetically ... pleasing surroundings" would better be attained by Alternative A. This alternative would eliminate the lagoon, which would be filled, graded, and seeded with native grasses. Otherwise, Alternatives A and B would meet this requirement in a similar manner. "Productive ... surroundings" would be better achieved by Alternative A, which would create a grassed field at the site of the filled lagoon. �•, Both alternatives would provide an equal "range of beneficial uses of the environment without degradation, risk of health or safety, or other undesirable and unintended consequences." The overall effect of either of the two alternatives would be moderate, beneficial effect on water quality and aquatic life through improved treatment capability. Oak, Using the same criterion, Alternative A would "attain the widest range of rAlk, beneficial uses of the environment" by creating more grassed area within the existing plant site. Both alternatives would help "preserve important historical, cultural, and natural aspects of our national heritage" by improving water quality in Flat Laurel Creek. �''► Since all construction would take place within the existing plant site, and no -41- cultural resources are present, neither alternative would have any effect on historical or cultural resources. Neither action alternative would provide beneficial reuse of water, but would provide improved treatment. Of the two action alternatives, Alternative A is environmentally preferred. The deciding factors include: The lagoon would not have to be filled, which would avoid the need to haul 4,500 cubic yards of fill dirt to the site, with the associated potential for soil erosion and truck traffic to and from the site; An overall smaller amount of land would be disturbed to upgrade the existing facilities. MITIGATION MEASURES FOR THE ACTION ALTERNATIVES For all action alternatives, best management practices and other mitigation measures would be used to prevent or minimize potential adverse effects associated with the construction and operation of the wastewater treatment plant. These practices and measures would be incorporated into the project construction documents and plans to reduce the magnitude of impacts and ensure that major adverse impacts would not occur. Mitigation measures undertaken during project implementation would include, but would not be limited to those listed below. The impact analysis in the "Environmental Consequences" section was performed assuming that these best management practices and mitigation measures would be implemented as part of all action alternatives. Practices to Minimize Effects on Water Quality and Aquatic Life Implementation of best management practices would result in local, direct, negligible effects on water quality resulting from soil erosion. All appropriate best management practices would be implemented during construction to prevent degradation of local waters and watersheds. These would include: Only clean fill, preferably from some site on the Parkway, shall be used. Any fill coming from off -site shall be inspected (as well as the site it came from) to reduce the chances for introduction of exotic plant species. Construction and other debris shall be disposed of according to Superintendent's Order #6, Solid Waste Disposal, dated July 16, a003. There should be no large tankers allowed on treatment plant road after construction. In the event any action is to be considered that could impact concession services in the Mt. Pisgah area, the Concessions Office shall be provided with advance notification of at least 3o days. Post construction mitigation measures would include sodding or seeding all exposed soils to prevent erosion, performing routine maintenance on all stormwater treatment -42- facilities, keeping trash and debris cleared up, and avoiding using chemical pesticides and fertilizers on the landscape. Practices to Minimize Effects on Special Status Species A survey of the wetland inside the fenced -in area will be conducted to delineate the boundaries of this resource more precisely so it can be avoided during construction and operation. In addition, the National Park Service will conduct a survey of the wetland to determine if any listed species of plants or animals are present in this wetland. The wetland will also be marked and avoided during construction and operation. - 43 - This page intentionally left blank —44— P" 1 �p �1 AFFECTED ENVIRONMENT, EVALUATION METHODOLOGY, AND ENVIRONMENTAL, CONSEQUENCES INTRODUCTION Affected Environment and Environmental Consequences This section describes the features of the affected environment that could potentially be affected by the proposed Mt. Pisgah Wastewater Treatment Plant project, and provides an assessment of the potential environmental consequences of each of the alternatives. A.,, The section is organized according to the previously described three impact topics, which allows for a standardized comparison between alternatives based on the most relevant issues. To facilitate the comparison of environmental consequences, the features of the affected environment for each impact topic are first described, followed by an assessment of the potential effects of each alternative. These include, in sequence, the No Action Alternative, Alternative B (the preferred alternative, extended aeration package plant) and Alternative A (upgrade existing plant). /Mb` The National Environmental Policy Act requires consideration of context, intensity and duration of environmental impacts, indirect impacts, cumulative impacts, and measures to mitigate impacts. National Park Service policy also requires that "impairment" of natural and cultural resources be evaluated in all environmental documents. These assessments are therefore provided for each impact topic in the discussion that follows. Methodology General Evaluation Methodology For each impact topic, the analysis includes a brief description of the affected environment and an evaluation of the effects of implementing each alternative. The impact analysis is based on information provided by national park service staff, relevant references and technical literature citations, and subject matter experts. The impact analyses involved the following steps. r, Define issues of concern, based on public scoping. em\ Identify the geographic area that could be affected. egm� Define the resources within that area that could be affected. ?=*% Compare the resources to the area of potential effect. 04h% Identify the effects caused by the alternative, in comparison to the baseline represented by the No Action Alternative, to determine the relative change in resource conditions. Characterize the effects based on the following factors: Whether the effect would be beneficial or adverse. The area affected by the alternative, such as local or regional. ,a•, Duration of the effect, either short-term or long-term. Unless an impact - topic -specific definition of these terms is provided, the following will be ANN used. /Awl — 45 — A short-term impact would last only a few days or weeks. A long-term impact would last several years or more, or would recur periodically over several years. The intensity of the effect, either negligible, minor, moderate, or major. Impact -topic -specific thresholds for each of these classifications are provided in each impact topic methodology section. Threshold values were developed based on federal and state standards, consultation with regulators from applicable agencies, and discussions with subject matter experts. Table 6 summarizes the impact thresholds used in this environmental assessment. Potential indirect effects of the proposed action. An example of an indirect effect would be changes in water quality caused by growth that is induced by a proposed project. However, the proposed project would cause negligible or no indirect effects in all cases. Therefore, analyses of indirect effects are not provided in this environmental assessment. Determine whether impairment would occur to resources and values that are considered necessary and appropriate to fulfill the purposes of the Blue Ridge Parkway. Determine cumulative -effects by evaluating the effect in conjunction with the past, current, or foreseeable future actions for the Mt. Pisgah Developed Area, Blue Ridge Parkway, and the region. If appropriate, identify mitigation measures that may be employed to offset potential adverse impacts. —46— 1r_U1 Ja inntT16rne1 t%1A Tlai initinnc Impact Topic Negligible Minor Moderate Major Duration Water Quality Impacts would not be Impacts would be Changes in water quality Changes in water quality Short-term - Following detectable.

'The Endangered Species Act defines the terminology used to assess impacts to listed species as follows: No effect — When a proposed action would not affect a listed species or designated critical habitat. May affect / not likely to adversely affect — Effects on special status species are discountable (i.e., extremely unlikely to occur and not able to be meaningfully measured, detected, or evaluated) or are completely beneficial. May affect / likely to adversely affect — When an adverse effect to a listed species may occur as a direct or indirect result of proposed actions and the effect either is not discountable or is completely beneficial. �1 r� Cumulative Effects Analysis Method The Council on Environmental Quality (1978) regulations for implementing the National Environmental Policy Act require assessment of cumulative effects in the decision -making process for federal actions. Cumulative effects are defined as "the impact on the environment which results from the incremental impact of the action when added to other past, present, and reasonably foreseeable future actions regardless of what agency (federal or non-federal) or person undertakes such other actions" (40 CFR 15o8.7). Cumulative effects are considered for both the no action alternative and the two action alternatives. Cumulative effects were determined by combining the effects of the alternative with other past, present, and reasonably foreseeable future actions. Therefore, it was necessary to identify other past, ongoing, or reasonably foreseeable future actions at the Mt. Pisgah Developed Area, within the Blue Ridge Parkway, and in the surrounding region. Past actions that have the potential to have a cumulative effect in conjunction with this wastewater management project include the rehabilitation of the Mt. Pisgah Developed r� Area, which was addressed in a previous environmental assessment. This project included the following components: Replace all water lines in campground Loops A and B. This consists of approximately 3200 feet of pipe that were placed in the existing sewer easement and about 96o feet in new areas. The existing water lines were abandoned in place, and the existing water line easements were allowed to re -vegetate. The rerouted sections would be: The 16o-foot line to a yard hydrant at south end of Loop A rerouted to avoid passing through two campsites. The main line that runs through Loops A and B rerouted to consolidate all utilities as much as possible into one easement. The new main water line was placed inside of the existing sewer line easements. Seven drinking fountains in the interior of Loops A and B were removed and replaced with eight new yard hydrants along the loop roads. This required five new sections of water line (approximately Boo feet total) within the loops. The routes of the lines were chosen to follow existing paths where possible and avoid large trees. The social trails to the existing drinking fountains were allowed to revegetate. Construct approximately 800 feet of new waterline from the restaurant/concessions area to Loop A. Approximately ioo feet of this route would pass through a wooded area. The route was chosen to avoid large trees. Replace approximately i000 feet of sewer line and five manholes in the restaurant/lodging area, including a crossing under the Blue Ridge Parkway. All lines were placed adjacent to the existing lines within the existing easement, except for a 250-foot section relocated io feet to avoid a building. The existing lines was abandoned in place. ,�•, — 49 — ANN Demolish the existing aboveground sewer line that crosses the wetland. The existing aboveground sewer line, concrete piers and the two sections of metal pipe was removed by crane to allow natural water flow through the current crossing area. Disturbance did extend further into the wetland. Construct a new ioo-foot long steel footbridge over the wetland. The maximum height of the bridge at the top of the railings was approximately io feet above the lowest point ground level of the crossing. The bridge railings was approximately 5 feet above ground level at each end of the bridge. New water and sewer lines were suspended from the bridge. Approximately 200 feet of water line in the existing easement inside Loop C were replaced to connect with the water line that crosses the bridge. All footings for the bridge were constructed outside of the delineated wetland area. Frequent removal of wetland vegetation was required. Replace approximately 4500 feet of water line on the west side of the Blue Ridge Parkway to the picnic area, and on the west side of the sewage treatment plant access road. This line was installed adjacent to the existing line within the existing easement. The existing asbestos -cement pipe was abandoned in place, except in certain locations where it had to be removed due to space constraints. An additional 400 feet of new water line was constructed in the shoulder of the picnic area access road, replacing a line that runs in an easement. The existing easement was then allowed to re -vegetate. Replace approximately 2600 feet of sewer line and 16 manholes from Loop C to the sewage treatment plant, and i000 feet from the picnic area to the sewage treatment plant. The existing lines was removed, but the manholes were reused if possible. Repave the access road to the sewage treatment plant. Demolish seven campsites adjacent to the bog. In Loop C, number 131 was removed, and in Loop B, numbers 37, 40, 44 42) 44, and 46 were removed. This included removal of pavement in parking slips, tent pad materials and edging, picnic tables, grills, trash receptacles, and curbstones. The natural grade of each site was restored and a layer of mulch was placed over the area. Construction of all of the above projects has been finished, except for some warranty work that is currently ongoing. The warranty work does not involve any construction and would not affect natural or cultural resources in any way. Future projects in the Mt. Pisgah Developed Area include: Upgrading and expanding the rooms at the Mt. Pisgah Inn, and installing low - flush toilets. This would reduce the flows to the wastewater treatment plant over what they are currently. Improvements to the country store. This is a upgrade of an existing facility would have no environmental effects. —50— f�1 l�1 f"'t1 Because there would be no land disturbing activities associated with these two projects, it was determined that they would have no adverse construction -related effects on natural or cultural resources. However, the reduction in flow resulting from installation of low -flow toilets in the Mt. Pisgah Inn would have beneficial effects, and these are included in the impact assessment. �► Impairment Analysis Method National Park Service Management Policies 200r (NPS 2000) require analysis of potential effects to determine whether or not actions would impair national park service resources or values. The fundamental purpose of the national park system, established by the Organic Act and reaffirmed by the General Authorities Act, as amended, begins with a mandate to conserve park resources and values. NPS managers must always seek ways to avoid, or to minimize to the greatest degree practicable, actions that would adversely affect park resources and values. These laws give the National Park Service the management discretion to allow impacts to park resources and values when necessary and appropriate to fulfill the purposes of a park, so long as the impact does not constitute impairment of the affected resources and values. Although Congress has given the National Park Service the management discretion to allow certain impacts within parks, that discretion is limited by the statutory requirement (enforceable by the federal courts) that the National Park Service must leave park resources and values unimpaired, unless a particular law directly and specifically provides otherwise. The impairment that is prohibited by the Organic Act and the General Authorities Act is an impact that, in the professional judgment of the responsible NPS manager, would harm the integrity of park resources or values, including the opportunities that otherwise would be present for the enjoyment of those resources or values. Impairment may result from NPS activities in managing the park, from visitor activities, or from activities undertaken by concessionaires, contractors, and others operating in the park. An impact to any park resource or value may constitute impairment. However, an impact would be most likely to constitute impairment if it affects a resource or value whose conservation is: Necessary to fulfill specific purposes identified in the establishing legislation or proclamation of the park; AVI` Key to the natural or cultural integrity of the park or to opportunities for enjoyment of the park; or Identified as a goal in the park's general management plan or other relevant NPS planning documents. A determination on impairment is included in the impact analysis section for all impact topics relating to Blue Ridge Park Way Area resources and values. It is based on the _ impact -topic -specific definition of impairment that is provided in each national recreation area resource and value impact topic methodology section. � — SI Water Quality Affected Environment The existing wastewater treatment plant discharges treated effluent to Flat Laurel Creek, an intermittent stream located approximately 1/8 of a mile downslope of the plant. Flat Laurel Creek is an upper tributary of Pisgah Creek, a tributary of the East Fork of the Pigeon River (Figure 4). Pisgah Creek is classified as a trout water by the State of North Carolina (NCWRC 20o6). Both creeks are located in the French Broad River basin, defined as United States Geological Survey Cataloging Unit o6010105 (EPA 2oo6). Water quality in this area is good, and none of the streams are listed on the 303(d) list (NC Division of Water Quality 20o6). The discharge to Flat Laurel Creek is permitted under the National Pollutant Discharge Elimination System. The permit does not specify a limit for ammonia, but the plant has been required by the State of North Carolina to conduct Whole Effluent Toxicity Testing in the last two years. In August 2004, the plant received an effluent chronic toxicity violation for failing the Whole Effluent Toxicity text for ammonia. No ammonia toxicity violations occurred in 2005 (NPS 20o6b). The discharge permit does not have a temperature limit, but the State of North Carolina requires that the difference in temperature above and below the discharge in Flat Laurel Creek differ by no more than % degree Centigrade. The temperature of the water in Flat Laurel Creek is therefore measured on a regular basis above and below the discharge point from the plant. This requirement has been met. The plant is located on a small, steep sided knoll above the Flat Laurel Creek drainage. Water quickly reaches Flat Laurel Creek via overland sheet flow during rain events, as well as from intermittent drainages above and below the site. The area surrounding the site is heavily forested, and the abundant vegetation and soil cover provides an effective filter for nonpoint runoff. The plant site contains approximately five acres of impervious and/or disturbed land upslope of Flat Laurel Creek. The rest of the Mt. Pisgah Developed Area also contains paved areas and other types of impervious surfaces such as rooftops at the Mt. Pisgah Inn, country store and other small buildings. Impacts of Alternative O: No Action / Continue Current Management Analysis: No new facilities would be constructed under the No Action Alternative. Therefore, levels of soil erosion and potential associated effects on water quality of Flat Laurel Creek would be similar to present conditions. Alternative O would therefore have no adverse construction -related effects on water quality. During operation under the No Action Alternative, the plant would continue to discharge treated effluent to Flat Laurel Creek, but at lower volumes than it does at present during the year, because of the installation of low flow toilets in the Mt. Pisgah Inn. The discharge limits of the National Pollutant Discharge Elimination System permit would continue to be met, except periodic excursions of ammonia toxicity would probably still occur. These excursions usually occur when the lagoon is drawn down during periods of peak use in late summer and fall, and the water in the lagoon comes into closer proximity to the solids on the bottom. With lower flows, however, these —52— !'1 excursions would be expected to be fewer, since the lagoon would not experience drawdown as frequently as it does currently, and the volume of wastewater would be . lower than at the present time. The temperature of the discharge from the wastewater treatment plant would continue to meet the % degree Centigrade requirement in Flat Laurel Creek. With lower discharge volumes, the potential for exceeding the temperature limits would be expected to be reduced. During operation, nonpoint runoff from the existing site would continue to be generated during rain events through sheet flow and via intermittent streams. Because the area below the site is densely forested, however, runoff from the site would continue to be filtered effectively. Water quality in Flat Laurel Creek and Pisgah Creek would therefore be similar to existing conditions. Overall, the No Action Alternative would have minor, local, long-term, adverse effects on water quality during operation. Cumulative Impacts: No new construction would occur at the wastewater treatment plant under the No Action Alternative, and all of the other construction projects in the Mt. Pisgah Developed Area are now complete, with the exception of the installation of the low flow toilets and conversion of the gas station to a country store. Since construction of these two remaining projects in the Mt. Pisgah Developed Area do not involve any land clearing, they will have no cumulative effects on water quality through soil erosion. Therefore, no construction -related cumulative effects on water quality would result under the No Action Alternative. Operation of the existing plant would be continued using the current procedures. Low flow toilets installed at the Mt. Pisgah Inn would reduce the amount of wastewater received by the plant. This would result in a minor, local, long-term, beneficial cumulative effect on water quality during operation. Conclusion: Since no new construction would occur under the No Action Alternative, this alternative would have no construction -related effects on water quality. During operation, the plant would be expected to continue to experience occasional violations of the ammonia test, however. Nonpoint runoff would also continue to be generated from the existing disturbed site, but would also continue to be filtered by the densely forested areas between the site and Flat Shoal Creek. Overall, the No Action Alternative would therefore have minor, local, long-term, adverse effects on water quality during operation. No new construction would occur at the treatment plant under the No Action #W'N Alternative, so there would be no cumulative construction -related effects on water quality under the No Action Alternative. During operation, however, low flow toilets installed at the Mt. Pisgah Inn would reduce the amount of wastewater received by the /MI, _ plant. This would result in a minor, local, long-term, beneficial cumulative effect on water quality. The No Action Alternative would not produce major adverse effects to water resources whose conservation is (i) necessary to fulfill specific purposes identified in the ,�,� — 53 — establishing legislation of the park, (a) key to the natural or cultural integrity of the park or opportunities for enjoyment of the park, or (3) identified as a goal in the park's general management plan or other National Park Service planning documents. Consequently, there would be no impairment of water resources or values as a result of the implementation of the No Action Alternative. Impacts of Alternative B: Extended Aeration Package System - Preferred Alternative Analysis: The potential effects of this alternative during construction on water quality are related to soil erosion. Soils would be disturbed in an approximately 70 x 15 foot area required for construction of the extended aeration package system. The package plant would be constructed in the eastern end of the site just inside the gate, which would require removal of the abandoned Imhoff sludge treatment tanks and sludge beds. Some additional new associated facilities would also be constructed that would result in soil disturbance. These activities would increase the potential for soil erosion and associated effects on water quality in Flat Laurel Creek during the grading and leveling of the site. These effects would be minimized by implementation of best management practices for soil erosion. A distinct feature of this alternative would be the filling of the 0.46-acre lagoon during construction. This would require hauling approximately 4,500 cubic yards of fill dirt from off site and placing it in the abandoned and drained lagoon. The filled lagoon would then be graded, compacted, and planted with native grasses. During and after the filling of the lagoon with new dirt, there would a potential for soil erosion and a reduction in water quality to occur in Flat Laurel Creek during rain events. These effects would be minimized by implementation of best management practices for soil erosion during and following filling of the lagoon. Because the lagoon would be filled under Alternative B, but remain in service under Alternative A, a larger area of disturbed soil would occur under Alternative B as compared with Alternative A. However, best management practices would be employed during construction to control soil erosion during filling of the lagoon. With these mitigation measures in place, the project would have minor, local, short-term effects on water quality in Flat laurel Creek during construction. During operation, a larger area of disturbed soils would exist on the site as compared with the No Action Alternative and Alternative A because the 0.46 acre lagoon would be filled and the surface would be grassed and maintained as an open area. This would increase the potential for erosion and subsequent effects on water quality of Flat Laurel Creek. However, best management practices would be employed to minimize the potential for soil erosion from the site during operation. Effects of nonpoint runoff during operation would therefore have minor, local, long-term, adverse effects on water quality during operation. Alternative B would result in improvements of the quality of the effluent during operation of the new plant. These improvements would minimize the potential for problems with ammonia toxicity in the effluent, since the lagoon would be eliminated, and a more efficient treatment system would be used. Temperature limits above and —54— �1 �t below the discharge point in Flat Laurel Creek would continue to be met. Sludge would be stored in a 25,000 gallon tank prior to removal once or twice a year to an approved facility. Sludge disposal would therefore have no effects on water quality in Flat Laurel �..►, Creek or elsewhere. Overall, operation of the new package plant under Alternative B would therefore result in a moderate, local, short-term beneficial effect on water quality. Cumulative Effects: All of the other construction projects in the Mt. Pisgah Developed Area are now complete, with the exception of the installation of the low flow toilets and conversion of the gas station to a country store. Since construction of these two remaining projects in the Mt. Pisgah Developed Area does not involve any land clearing, these projects will have no effects on water quality through soil erosion. Therefore, no construction -related cumulative effects on water quality would result under Alternative B. 0"k, Operation of the new low -flow toilets in the Mt. Pisgah Inn will reduce the amount of wastewater generated and treated at the new package plant. The operation of the new package plant under Alternative B would also result in an improvement in water quality of the flow that is received from the developed area. The combined effect would therefore be an improvement over existing conditions. Therefore, Alternative B would result in minor, local, long-term beneficial cumulative effects on water quality. Conclusion: There would be a potential for soil erosion and reduction in water quality ,a•, in Flat Laurel Creek during the grading and leveling of the site where the package plant and other new facilities are constructed. These effects would be minimized by implementation of best management practices for soil erosion during and following filling of the lagoon. The project would therefore have minor, local, short-term effects on water quality in Flat laurel Creek during construction. /Ml� During operation, Alternative B would result in improvements of the quality of the effluent during operation of the new plant.

The extent of disturbed area created under Alternative A, however, would be 0.46 acres less than Alternative B because the lagoon would not be filled in Alternative A. There would still be a potential to affect water quality in Flat Laurel Creek, however, during construction. Construction would therefore have minor, local, short-term adverse effects on water quality. These potential adverse effects would be mitigated by implementation of best management practices. During operation under Alternative A, the upgraded plant would discharge treated effluent to Flat Laurel Creek. The quality of the effluent would be improved as compared with the existing plant. The discharge limits of the National Pollutant Discharge Elimination System permit would continue to be met, and the potential for periodic excursions of ammonia toxicity would be minimized. The temperature requirements for Flat Laurel Creek would continue to be met. Sludge would be disposed off site in an approved facility. During operation, this alternative would therefore have local, minor and long-term beneficial effects on water quality. Cumulative Impacts: The cumulative effects of Alternative A would be similar to Alternative B. Conclusion: The effects of Alternative A on water quality during construction would be similar to the effects of Alternative B, since land would still be cleared on the site for the new facilities.

No detailed information on the aquatic life of Flat Laurel Creek is currently available. However, it is known that Pisgah Creek is managed as trout waters by the State of North Carolina (NCWRC 20o6). A small stream also flows down the slope immediately above the plant where it then flows into a small emergent wetland located just inside the plant fence, near the entrance gate. Based on the soils survey and maps completed by the Natural Resource Conservation Service in 2002, this is an intermittent stream that originates above the plant site. This stream is also the primary water supply for the wetland inside the plant site, which is located along and on either side of the stream. No aquatic surveys of this OWN stream have been conducted to date, but it would be expected to support diverse and abundant populations of benthic invertebrates and possibly, amphibians. The stream flows onto the site from above the plant in a southerly direction, then turns sharply to Ask% the east alongside the main plant road inside the fence. At this point the stream is approximately 1-2 feet wide. It then flows underneath the plant road through two culverts, and continues to the east at the end of the abandoned sludge drying beds. The stream then courses south around the end of the sludge drying beds, and then moves off - site and downslope below the plant, where it ultimately connects to Flat Laurel Creek at the bottom of the hill. This stream and associated wetland would be completely avoided An. during construction. Impacts of Alternative O: No Action / Continue Current Management Analysis: The potential effects of the No Action Alternative on aquatic life in Flat Laurel Creek and Pisgah Creek are related to potential effects on water quality from point and o`' nonpoint discharges from the plant, since water quality directly influences the abundance and distribution of fish and benthic invertebrates. Since no new facilities would be constructed under the No Action Alternative, however, this alternative would have no construction -related effects on aquatic life in Flat Laurel Creek. During continued operation of the existing facility, the plant would continue to discharge treated effluent to Flat Laurel Creek, but at lower volumes, fewer periodic excursions of ammonia toxicity would probably occur, and temperature requirements would continue to be met in Flat Laurel Creek. Nonpoint runoff from the existing site would continue to be generated and would still be filtered effectively by forested areas located down slope of the site. Overall, the No Action Alternative would therefore have �+ minor, local, long-term, adverse effects on aquatic life in Flat Creek during operation. No adverse effects on aquatic life of Pisgah Creek, located several miles downstream of Flat Laurel Creek, are known to occur or are expected to occur in the future as a result of the discharge from the Mt. Pisgah treatment plant. Cumulative Impacts: Cumulative effects of the No Action Alternative on aquatic life would parallel the cumulative effects on water quality, since the two are related. No new �►, construction would occur at the treatment plant under the No Action Alternative, so ,� — 57 — there would be no cumulative construction -related effects on aquatic life under the No Action Alternative. During operation, however, low flow toilets installed at the Mt. Pisgah Inn would reduce the amount of wastewater received by the plant. This would result in a minor, local, long-term, beneficial cumulative effect on aquatic life in Flat Laurel Creek. Conclusion: Since no new facilities would be constructed under the No Action Alternative, this alternative would have no construction -related effects on aquatic life in Flat Laurel Creek. During operation, the effects on aquatic life would parallel effects on water quality. The plant would continue to discharge treated effluent to Flat Laurel Creek, but at lower volumes, fewer periodic excursions of ammonia toxicity would probably occur, and temperature requirements would be met in Flat Laurel Creek. Nonpoint runoff from the existing site would continue to be generated and would continue to be filtered effectively by forested areas. Overall, the No Action Alternative would therefore have minor, local, long-term, adverse effects on aquatic life in Flat Creek during operation. Cumulative effects of the No Action Alternative on aquatic life would parallel the cumulative effects on water quality, since the two are related. The No Action Alternative would have minor, local, long-term, beneficial cumulative effects on aquatic life. Alternative O would not produce major adverse effects to aquatic life whose conservation is (i) necessary to fulfill specific purposes identified in the establishing legislation of the park, (2) key to the natural or cultural integrity of the park or opportunities for enjoyment of the park, or (3) identified as a goal in the park's general management plan or other National Park Service planning documents. Consequently, there would be no impairment of aquatic life or values as a result of the implementation of Alternative O. Impacts of Alternative B: Extended Aeration Package System - Preferred Alternative Analysis: The potential effects of this alternative during construction on aquatic life are directly related to effects on water quality caused by soil erosion. The primary construction activities that could affect aquatic life under Alternative B are construction of the extended aeration package system, filling of the 0.46-acre lagoon, removal of the abandoned Imhoff sludge treatment tanks and sludge beds and some other minor new associated facilities. However, since best management practices will be implemented to control soils erosion, construction activities associated with Alternative B would only have the potential for producing minor, local, short-term effects on aquatic life. During operation, erosion of soil from the filled and stabilized lagoon could affect aquatic life in Flat Laurel Creek. However, best management practices would be employed to minimize the potential for soil erosion from the site during operation. Effects of nonpoint runoff during operation would therefore have negligible, local, long- term, adverse effects on aquatic life during operation. Alternative B would result in improvements in the quality of the effluent during operation of the new plant. These improvements would minimize the potential for — 58 — EAMS /19*1 `� problems with ammonia toxicity affecting aquatic life, since the lagoon would be eliminated, and a more efficient treatment system would be used. Temperature limits above and below the discharge point in Flat Laurel Creek would continue to be met. Sludge would be stored in a a5,000 gallon tank prior to removal once or twice a year to an approved facility. Sludge disposal would therefore have no effects on aquatic life in Flat Laurel Creek. Overall, operation of the new package plant under Alternative B would therefore result in minor, local, short-term beneficial effects on aquatic life. Cumulative Effects: All of the other construction projects in the Mt. Pisgah Developed Area are now complete, with the exception of the installation of the low flow toilets and conversion of the gas station to a country store. Since construction of these two remaining projects in the Mt. Pisgah Developed Area do not involve any land clearing, they will have no effects on aquatic life in Flat Laurel Creek. Therefore, no adverse �► construction -related cumulative effects on aquatic life would result under Alternative B. Operation of the new low -flow toilets in the Mt. Pisgah Inn will reduce the amount of wastewater generated in the future. Operation of the new package plant under Alternative B would result in an improvement in water quality of the effluent, with associated beneficial effects on aquatic life in Flat Laurel Creek. Alternative B would therefore result in minor, local, long-term beneficial cumulative effects on aquatic life. Conclusion: There would be a potential for soil erosion and associated minor, local, long-term adverse effects on aquatic life in Flat Laurel Creek during the grading and leveling of any part of the site where the package plant and other new facilities were _ constructed. These effects would be minimized by implementation of best management practices for soil erosion. During operation, a larger area of disturbed soils would exist on the site as compared �► with the No Action Alternative and Alternative A, but best management practices would r� be employed to minimize the potential for soil erosion. Effects of nonpoint runoff during operation would therefore have negligible, local, long-term, adverse effects on aquatic life during operation. Alternative B would result in improvements of the quality of the effluent during operation of the new plant that would minimize the potential for ammonia toxicity effects on aquatic life.

Potential adverse effects of construction would be minimized by implementation of best management practices. During operation under Alternative A, the upgraded plant would discharge treated effluent to Flat Laurel Creek. The quality of the effluent would be unproved as compared with the existing plant. The discharge limits of the National Pollutant Discharge Elimination System permit would continue to be met, and the potential for periodic excursions of ammonia toxicity would be minimized due to the upgraded facilities. The temperature requirements for Flat Laurel Creek would continue to be met. Less nonpoint runoff would be generated from the site as compared with Alternative B since the lagoon would not have to be filled. During operation, the overall effects of this alternative would have minor, local, and long-term beneficial effects on water quality. Cumulative Impacts: The cumulative effects of Alternative A on water quality would be similar to Alternative B. Conclusion: The effects of Alternative A on water quality during construction would be similar to the effects of Alternative B, since land would still be cleared on the site for the new facilities.

Consequently, there would be no impairment of water quality or values as a result of the implementation of Alternative A. Special Status Species Affected Environment The previous environmental assessment completed in conjunction with the rehabilitation of the Mt. Pisgah Developed Area (NPS 2003) included an assessment of the actual or potential occurrence of federally and state listed species of plants and animals in the area. Since the proposed wastewater treatment plant site is included within the Mt. Pisgah Developed Area, the information contained in the previous environmental assessment is sufficient for use as a starting point in the present environmental assessment. However, as part of the preparation for the wastewater treatment plant environmental assessment, the information presented previously was reviewed and updated based on personal communications with the park staff and available literature. The previous environmental assessment also included correspondence with the United States Fish and Wildlife Service regarding the actual or potential occurrence of listed species in the Mt. Pisgah Developed Area (Appendix B, from NPS 2003). An updated list of species and their current status is provided in Table 7. OWN Since the site of the proposed wastewater treatment project is completely cleared of natural upland vegetation, it is highly unlikely that any listed species of plants or animals OXON occur in upland habitats on the site itself within the fenced -in area. A variety of listed species do occur, however, in the Mt. Pisgah Developed area and other areas surrounding the site (Table 7). In addition, a small wetland and an intermittent stream occur in the northeast corner of the site just inside the fence line and has a potential to harbor protected species. However, a qualitative field survey of this wetland by the National Park Service was conducted in December 2005, and it was estimated that the wetland and intermittent stream were unlikely to harbor any listed species. A detailed investigation has not been completed to date, so this area will be avoided during construction of any new wastewater treatment plant facilities. A survey of the wetland and stream will be completed by the National Park Service prior to construction of the new facilities, however. The previous environmental assessment included consideration of the potential effects of all road and utility work in the developed area, including the access road to the !� wastewater treatment plant. Construction activities associated with the access road itself have therefore not been included in the present environmental assessment. The following sections provide a summary of the available information on listed species that could occur on the wastewater treatment site or in the surrounding Mt. Pisgah Developed Area. The information from the previous environmental assessment is described first, followed by an update of the most recent information. Please refer to ,ram, Table 7 for a summary. Table 7.

This species has been observed in the Mt. Pisgah Developed Area recently. It is currently classified as a state species of concern, S3, G4 (Table 7). Conversations with researchers who use the area, as well as a knowledgeable camper, confirm that bog lemmings (not presently listed), red crossbills and saw whet owls are present. Two saw -whet owls were observed in a 2005 survey by the National Park Service. The National Park Service has observed red crossbills, northern bobwhite (not presently listed), black -billed cuckoo, and woodcock (not presently listed) in the area in the last two years. National Park Service surveys of nest boxes throughout the developed area have been positive for northern flying squirrel in 2002 and 2004. There is a potential for the Carolina northern flying squirrels to occur along the access road leading to the proposed wastewater treatment plant site. No squirrels have been observed along the access road by the National Park service to date, but they do occur on both sides of the treatment plant. Therefore, it is likely that they use the area, and could occupy trees in the vicinity of the access road. No —63— squirrels have been caught in the nest boxes that the National Park Service has placed closest to the access road. Bat surveys were conducted using mist -netting in July of zoos. No federally -listed species were collected. One mature northern long-eared myotis (Myotis septentrionalis)(State Species of Concern) was caught near the treatment plant and picnic area (not the campground/inn area)(NPS 2005a). The previous environmental assessment (NPS 2003) presented the following summary of information on federally -listed species: "The only federally listed species that is known to occur in the project area is the endangered Carolina northern flying squirrel (Glaucomys sabrinus coloratus). According to the USFWS, the Carolina northern flying squirrel `shows a relict distribution and tends to occupy rather small and potentially vulnerable islands of high elevation habitat.' The Carolina northern flying squirrel has most commonly been captured in conifer -hardwood forests comprised of spruce and fir, with beech, yellow birch, sugar maple, red maple, hemlock, and black cherry (USFWS,19go). Individuals have also been captured in riparian hemlock - hardwood -rhododendron forests. The Carolina northern flying squirrel is vulnerable to human impacts such as habitat destruction, fragmentation, or alterations associated with the clearing of forests; recreational and residential development; introduced exotic pests; and pollution (USFWS,1999)•" "All of the above tree species are present in the Mt. Pisgah area. However, there are pockets of habitat that consist primarily of spruce, fir, hemlock, and yellow birch. Northern flying squirrels have been captured primarily from this type of vegetation, especially where this type of vegetation consists of widely spaced mature trees with an abundance of standing and downed snags. Pockets of this type of habitat are located in the picnic area, Loop C of the campground, along the trail between the Mt. Pisgah trail and the picnic area, along the trail between the picnic area and the campground, and on the east side of the Parkway in several sections between the Parkway and the Buck Springs Trail. One northern flying squirrel was captured in a live trap in the picnic area during the summer of 2001. In addition, the acidic cove community in the Mt. Pisgah Developed Area consists primarily of riparian hemlock -hardwood -rhododendron forest, which represents additional potential habitat." "There are historic records for the endangered eastern cougar (Felis concolor cougar) from the Mt. Pisgah area. The cougar's decline has been attributed primarily to pressure from hunting as well as land development. In the late 1800's the cougar was reported as extirpated. In i91o, and again in the 1970's and 8o's there have been several unconfirmed sightings and scat in the area of Mt. Pisgah. There have been recent cougar sightings within the Mt. Pisgah Developed Area by Pisgah Inn staff and Parkway maintenance employees. Some biologists suggest that these cougars have been raised in captivity and then released." "Although the wetland within the [Mt. Pisgah Developed Area campground] site represents potential habitat for the mountain sweet pitcher plant (Sarracenia —64— ,ate �1 jonesii) (endangered) and the bog turtle (Glyptemys muhlenbergii) (threatened due to similarity of appearanceNto what?), extensive surveys of the wetland have �"► failed to document the occurrence of either of these species. Surveys of the remainder of the project area conducted by National Park Service biologists have failed to document the occurrence of any additional federally listed species �' within the project area." National Park Service staff familiar with the wastewater treatment plant site (NPS, 2005a) indicated the following concerning federally -listed species: Federal Species of Concern The previous environmental assessment (NPS 2003) presented the following summary of information on federally -listed species: "Federal Species of Concern that have been confirmed from the project area include the saw -whet owl (Aegolius acadius acadius), Appalachian cottontail (Sylvilagus obscurus), olive -sided flycatcher (Contopus cooperi), cerulean warbler (Dendroica cerulea), southern Appalachian black -capped chickadee (Docile atricapilla practica), and fraser fir (Abies frasera). Fraser fir was apparently planted in the project area and is not established as a natural population at the site (Pittillo and Green 2000). Historical records exist for yellow -bellied sapsucker (YBS) and Appalachian Bewick's wren at Mt. Pisgah. Surveys in 2003 for YBS failed to document the occurrence of this species at the site. The last known breeding site for Appalachian Bewick's wren was at Mt. Pisgah. It is likely extirpated from the site since no observations have been made in recent years." The current status of each these species was reviewed and the following was concluded: The Southern Appalachian northern saw -whet owl has been observed in the Mt. Pisgah Developed Area during National Park Service surveys (NPS 2oo5a). r�q Conversations with researchers who use the area as well as a knowledgeable $AIN camper, confirm that the northern saw -whet owl is present in the Mt. Pisgah Developed Area (NPS 2005a). The Southern Appalachian red crossbill (Loxia curvirostra pop) has been OW, observed in the Mt. Pisgah Developed Area during National Park Service surveys IM&N (NPS 2005a). e0b� State Listed Species 100� The previous environmental assessment (NPS 2003) presented the following summary of information on state -listed species: "Additional species listed only by the State of North Carolina that have been confirmed from the project area include the golden -crowned kinglet (Regulus satrapa), timber rattlesnake (Crotalus horridus horridus), sticky bog asphodel ,,•� (Tofieldia glutinosa), bog goldenrod (Solidago uliginosa), roan rattlesnake root (Prenanthes roanensis), Cuthbert's turtlehead (Chelone cuthbertii), granite dome bluet (Houstonia longifolia var. glabra), plains sunrose (Helianthemum bicknelliz), least moonwort (Botrychium simplex var. simplex), pinkshell azalea —65— (Rhododendron vaseyi), and American fly honeysuckle (Lonicera canadensis). In addition, three Watch List species [red -breasted nuthatch (Sitta canadensis), tawny cottongrass (Eriophorum virginicum), and mountain St. John's -wort (Hypericum buckleyt)] also have been confirmed in the project area." The current status of each these species was reviewed and is was concluded nothing had changed except the status of the timber rattlesnake, which is listed as a North Carolina Species of Concern, S3, G4 (NCHP 20o6), and which has been observed in the Mount Pisgah Developed area (NPS 2005a). The North Carolina Wildlife Resource Commission (NCWRC 20o6) were contacted and they stated that no sensitive or rare species occurred in Flat Laurel Creek. Impacts of Alternative O: No Action / Continue Current Management Analysis: New construction would not take place on the existing site under the No Action Alternative and therefore, construction would have no effect on state- or federally -listed species. Also, the site is completely cleared and no state- or federally - listed species of plants or animals occur in upland habitats site. There is a potential for listed species to occur in the wetland located inside the fence on the existing plant site, but this has yet to be confirmed by an actual survey. This area would be delineated and avoided during construction. The northern flying squirrel could occur in trees along the access road to the plant, but no new construction would occur in this area under Alternative O. In conclusion, since there would be no new construction activities on the site under the No Action Alternative and no listed species occur within the construction area, these activities would have no effect on state- or federally -listed species of plants or animals. Continued operation of the existing plant would have no effect on state- or federally - listed species within upland habitats in the fenced -in site, since none of these species are present in this area. The continued discharge of treated wastewater to Flat Laurel Creek would have no effect on state- or federally -listed species, since no listed species are known to occur in this creek. Cumulative Impacts: Continued operation of the existing wastewater treatment plant would not result in adverse cumulative effects on state- or federally -listed species, since there would be no direct effects on these species on the plant site or surrounding area resulting from construction or operation of the plant. Conclusion: Construction activities would have no effect on state- or federally -listed species of plants or animals under the No Action Alternative since no listed species occur in the construction area, and no construction would occur under this alternative. Continued operation of the existing plant would have no effect on state- or federally - listed species within upland habitats inside the fenced -in site, because none of these species are present on the plant site. The continued discharge of treated wastewater to Flat Laurel Creek would have no adverse effect on state- or federally -listed species since these species do not occur in the creek. Alternative O would not produce major adverse effects to state- or listed species whose conservation is (i) necessary to fulfill specific purposes identified in the establishing �1 legislation of the park, (2) key to the natural or cultural integrity of the park or opportunities for enjoyment of the park, or (3) identified as a goal in the park's general management plan or other National Park Service planning documents. Consequently, ,.y there would be no impairment of listed species or values as a result of the implementation of Alternative O. Impacts of Alternative B: Extended Aeration Package System -Preferred Alternative Analysis: A new package plant would be constructed on the existing site under Alternative B, and the lagoon would be filled.

CONSULTATION AND COORDINATION Scoping is the effort to involve agencies and the general public in determining the scope of issues to be addressed in the environmental document. Among other tasks, scoping determines important issues and eliminates issues that are not important; allocates assignments among the interdisciplinary team members and other participating agencies; identifies related projects and associated documents; identifies other permits, surveys, and consultations required by other agencies; and creates a schedule which allows adequate time to prepare and distribute the environmental document for public review and comment before a final decision is made. Scoping includes any interested agency or any agency with jurisdiction by law or expertise (including the Advisory Council on Historic Preservation, the State Historic Preservation Officer, and Indian tribes) to obtain early input (see Appendix Q. The National Park Service conducted internal scoping and external scoping for this project. Internal scoping was conducted with appropriate National Park Service staff in November 2oo6. External scoping included the letters to the agencies, and a newsletter published in May, 2oo6. A public news release announcing the project and requesting input was also published on April 13, 2oo6 (Appendix Q. Copies of the responses received from the agencies are included in Appendix C.

Pisgah Wastewater Treatment Plant Improvements Package: BLRI-081430 Date: October 13, 2005 Component Evaluated: Wastewater Treatment Facility Improvements Phase I - Information: diaphragm pump is located in a separate concrete chamber for pumping, settled sludge out of the lagoon. Background Information/Special Coneems/Constraints/Previous Decisions/Description of Present Proposal/Design Assumptions Alternative A: Upgrade Existing Aerated Lagoon Facility The Blue Ridge Parkway (BRP) maintains the Mt. Pisgah inn, a Lagoons systems similar to the facultative lagoon at Nit. Pisgah are in campground, trailer waste disposal and associated facilities in the Mt. operation throughout the country to comply with effluent standards Pisgah area, located near mile 410 of the BRP approximately 20 miles similar to those for Mt. Pisgah (30'mg/l BOD and TSS). The presence south of Asheville, NC. These combined facilities generate of filters downstream of the lagoon'incrbases the likelihood of meeting approximately 15,000 gallons per day (gpd) average of municipal plus the effluent requirements considerably. Without the filters, algae in trailer disposal wastewater during the operating season from April the effluent can be attributed to effluent TSS violations during high through November with peaks of 30,000 gpd during holiday algae growth seasons. weekends. The existing aerated lagoon facility meets NPDES effluent requirements on a regular basis with the exception of some infrequent This alternative would focus primarily on improving the sludge whole effluent toxicity (WET) biomonitoring excursions. These removal system and solids storage/treatment capabilities onsite. Per excursions are likely attributed to effluent ammonia toxicity. the July S, 2005 HDR Technical Memorandum (TM), it was determined that excessive sludge accumulation in the lagoons over the The liquid treatment scheme follows: plant influent is conveyed via operating season is the likely cause of the prior WET excursions. A gravity to the 0.46 acre; three -compartment aerated lagoon and diesel -driven pump on a floating barge would be installed in the pumped from the lagoon effluent transfer station to the lobe tank. lagoon to facilitate more frequent sludge removal from the lagoon. There are two existing effluent transfer (submersible type) pump units. The lagoon sludge pump would convey solids to a 25,000 gallon steel Plant flow is then pumped through the filters; chlorinated and sludge storage tank. A 2.5 HP progressing cavity sludge transfer deehlorinated before being discharged to Flat Laurel Creek. A pumps would be located next to the storage tank, so that sludge could National Park Service 4 U.S. Department of the Interior Final vesionAllom —79— be transferred at the end of the season to a sludge disposal truck. Many facility improvements would also be incorporated into this project including: sludge drying bed and Imhoff tank demolition, office building improvements, partial plant asphalt drive reconstruction, and a new emergency electrical generator. This alternative offers the advantage of low cost, but the disadvantage of potential WET test excursions and lagoon safety concerns. Alternative B: Construct Extended Aeration Package Treatment System Pre-engineered, pre -fabricated extended aeration activated sludge wastewater treatment facilities are commonly used for flow ranges similar to Mount Pisgah. These systems apply the same biochemical technologies frequently used in larger facilities, but can be procured in a fully enclosed system designed for smaller flow ranges. If properly operated and maintained, extended aeration package treatment facilities produce acceptable effluent quality, and low levels of BOD, TSS and NI13. The effluent from the package facility can either be conveyed to the existing filters or bypass the existing fitters. In this scenario, the lagoon would be taken out -of -service and a new plant influent pumping station wetwell with short-term equalization storage constructed. Two submersible plumps would be provided in the pumping station. The extended aeration package plant would be mounted to a concrete slab -on -grade. The exterior dimensions of the pre -fabricated structure are approximately 70' (length) by 15' (wide) by 15' (height). Within the structure, the following zones are present: sludge thickening/storage zone, aeration zone, clarifter zone, and a disinfection contact zone (if needed). The sludge thickcning/storage zone would temporarily hold biosolids generated in the system until solids are conveyed to a new onsite sludge storagettreatment facility. Sludge would be gravity conveyed to a 25,000 gallon steel sludge storage tank. A 2.5 HR progressing cavity sludge transfer pumps would be located next to the storage tank, so that sludge could be transferred to a sludge disposal truck. Sludge drying bed and Imhoff tank demolition would also be included in this Project. To facilitate facility reliability, a new 25 kW generator would also be included in this Project. Advantages of the extended aeration package treatment facility are the relatively low cost, high degree of reliability, and compact footprint. Alternative C: Polishing Constructed Wetlands Addition J.F. New and Associates prepared a Preliminary Engineering Study (PES) in August 2001 that evaluated a constructed wetlands treatment system to either supplement or replace the lagoon system. In the PES, it was assumed that more stringent effluent permit would be issued in December 2001 and that more stringent effluent ammonia or other nutrients standards would be enforced. To -date, this yet to occur. Two TOR TMs and an independent Olver, Inc. report were generated to evaluate the feasibility of replacing the aerated lagoon treatment system with a constructed wetlands waste treatment system. Both parties agreed that this was not a feasible alternative. The system has the following disadvantages: 1) Based on preliminary sizing requirements of 20 lbs BOD/(acre day), 3.5 acres to 5.0 acres of constructed wetland area would be required to treat the Mt. Pisgah wastewater. This magnitude of acreage is not available at the Mt. Pisgah site; 2) Site constraints at the treatment facility site would severely limit construction of any additional wetlands beyond the site limits without considerable earthwork activities and cost.; 3) Per discussions with NCDENR, regulatory approval of a constructed wetland system for the Mt. Pisgah site would be challenging; 4) Vegetation planted in the wetlands would require harvesting in the fall. In our TM dated July 8, 2005, it was determined that the only feasible way to integrate a wetland system at Mt. Pisgah is via a polishing National Park Service ♦ U.S. Department of the Interior Final venison:1110% ) l .➢ ➢ ) ) ),) ) ) ➢ ) ) l ) ➢ ) ) ) ) ) ) ),l l )1) ➢ ) ) ) ) ) ) ) ) ) ),l ) l )�) ) wetland. An 0.3 acre polishing wetland system could be located downstream of the existing filters and the aerated lagoon system would remain in-service. This alternative is being considered, since this alternative would promote "green" solutions for the park service. Plant effluent would flow in and.out of the wetland Aa gravity, so no additional mechanical or electrical components will be required for this alternative. However, this alternative does not remove any of the existing mechanical system components from service. Alternative D; Install Recirculating Sand Filtration System The National Park Service has had success with recirculating sand filtration systems at other sites and recommended that this alternative be considered for Mt. Pisgah. The recirculating sand filter would require a minimum.92' by IS' footprint to treat 30,000 gpd flow. Three septic tanks, a recirculating tank, and recirculation pumps will also be required ,for this alternative. Due, to the areal requirements of this alternative, the only feasible sand filter and tank location is within the aerated lagoon' footprint. This option will utilize a considerable amount of compacted fill dirt to bring the top of filter/tank elevations up to existing grade. A concrete containment barrier would also be poured around the filter, perimeter. Per conversations with a recirculatingsand filter manufacturer, the recirculating sand filter can be anticipated to produce BOD and TSS effluent quality less than 10 mg/L. Additionally, ammonia reduction is expected to be in the 40- 5041 range. Advantages of the recirculating sand filter system include prior experience with the system at other NPS facilities while disadvantages include limited filter construction period due to the need to utili7.e the aerated lagoon area. Alternative E: Install Membrane Bioreactor (MBR) Package Treatment System An MBR package system, an innovative alternative in wastewater treatment, is similar in some respects to the extended aeration package treatment facility. The MBR uses membrane technology to separate mixed liquor suspended solids (MISS) in the aeration basin from treated effluent rather than a gravity separation clarifier used in typical activated sludge processes. Similar sludge production would be expected from both systems. MBR systems produce superior effluent quality compared to the most other wastewater treatment technologies due to the very small membrane pore space. Anticipated effluent quality would be BOD and TSS concentrations less than 5 mg/L and Ammonia concentration less than .1 mg/L. In this scenario, the lagoon would be taken out -of -service and a new plant influent pumping station wetwell with short-term equalization storage constructed. Two submersible pumps would be provided in the pumping station. The MBR package plant would be mounted to a concrete slab -on -grade. The exterior dimensions of the pre -fabricated structure are approximately 50' (length) by 15' (wide) by 15' (height). Within the structure, the.following zones are present: influent holding tank, anoxic basin, aeration basin, and a membrane basin (two cells). The existing chlorination and dechlorination facilities would be utilized. A pre-programmed PLC and process control panel would be provided and would control the system and all process components. Advantages of the MBR system include the superior effluent quality while disadvantages include higher capital and operating costs (compared to an extended aeration facility). Alternative F: Install Membrane Bioreactor (MBR) Package Treatment System w/Ultraviolet (UV) Disinfection National Park Service ♦ U.S. Department of the Interior RQ81 veM1O=111WW —gI— This alternative is identical to Alternative E except that the existing anticipated Orenco system effluent quality would be in the 20 mg/l chlorination/dechlorination equipment would be taken out -of -service BOD, 20 mg/L TSS, and 5-10 mgfL Ammonia concentration range. and a new in -line UV disinfection unit installed. Thus, it is anticipated that the existing effluent filters will have to remain in-service. Advantages of installing a UV disinfection system in conjunction with the MBR system include elimination of chlorine discharge to the Advantages of the Orenco system include prior experience with the environment and elimination of chlorination/dechlorination chemicals system at other NPS facilities while disadvantages include a onsite while disadvantages include the capital cost associated with proprietary membrane technology required for long-term system purchasing the UV equipment. operation. Alternative G: Install Sequencing Batch Reactor (SBR) Treatment System An SBR treatment system would be constructed to replace the existing aerated lagoon. NPS has used SBR technology successfully at other sites. Two concrete basins would require construction with minimum dimensions (LWD)16' by 14' by 19% The SBR system requires a minimum sidewater depth of 16'. There is a considerable amount of rock in this area and it is very likely that rock would be encountered while constructing these basins. The anticipated SBR effluent quality will likely be in the 20-15 mgtl BOD, 20-15 mg/L TSS, and 5 mg/L Ammonia concentration range. Thus, it is anticipated that. the existing effluent filters will have to remain in-service. Advantages of the SBR system include -prior experience with (fie system at other NPS facilities while disadvantages include excessive sidewater depth requirements and anticipated effluent quality similar to the existing aerated lagoon system. Alternative H: Install Orenco Advantex Filtration System Eight, 5,000 GPD Orenco Advantex Filtration system modules would replace the aerated lagoon. NPS has used this technology successfully at other sites and wanted to evaluate this technology for this location. The filter modules have dimensions (LWD)16' by 8' by 4% The National Park Service * U.S. Department of the Interior Final vemloc:A/taQb -82- 1))))))))))1))))➢)))j))))))l)))ll)ll)))) Phase II - Functional Analysis: 1.

Phase V — Development: NPS has $1.13 M available funds for this construction project. All of the considered alternatives were initially considered viable for the site except for Alternatives 0 —Do Nothing, C — Polishing Wetlands Addition, and H — Install Orenco Advantex Filtration System. Alternative C did not achieve project objectives for the capital money required. Alternative H is a proprietary product that caused concerns regarding future filter media replacement. The capital cost for three (Alternatives D, F, and G) of the seven alternatives exceeded the available construction funding for the project. Thus, Alternatives A, B, and E remained viable. Alternatives A and B have similar capital and life cycle cost. Alternative E has a higher capital and life cycle cost, but provides superior effluent quality compared to Alternatives A and B.

The project team decided that Alternative B: Construct Extended Aeration Package Treatment System would be more feasible than Alternative A: Upgrade Existing Aerated Lagoon Facility. Phase VI - Recommendations: The team selected Alternative B: Construct Extended Aeration .Package Treatment System as the preferredi alternative. Relative to Alternative A, Alternative B would essentially provide NPS with a brand-new treatment facility for approximately the same capital cost. Concerns were expressed regarding spending capital to improve existing facilities relative to the age of the existing aerated lagoon system. Additionally. the plant operator has prior operating experience with extended aeration package plants and prefers this type of facility over the lagoon system. Package plant effluent quality should be the same or slightly better than the existing facility. Extended aeration package plants also have a long -history of operating experience and are considered a time -proven technology. The tentative location for the package plant is in the current sludge drying bed and Imhoff tank area. Neither facility is in use and would be demolished. The lagoon area may also be filled in with compacted dirt and useable plant site area increased by almost 0.5 acres. Since extended aeration package plants are a proven wastewater treatment technology, the NCDENR permitting process should also be simplified. Phase VH - Implementation The value analysis study was conducted on October 13, 2005, in Asheville, NC. NPS team to present this preferred alternative to the DAB in March 2006 for approval. If approval is granted, design document development would begin in June 2006.

The information on which these lists is based comes from a variety of sources, including field surveys, museums, herbaria, scientific literature, and personal communications. These lists are dynamic, with new records continually being added and old records being revised as new information is received. As a result, a list cannot be considered a definitive record of the elements of natural diversity present in a given county or quad and should not be used as a substitute for field surveys. When this information is used in any document, we request that the date this list was compiled be given and that the NC Natural Heritage Program be credited.

C Candidate Species which are very rare in North Carolina, generally with 1-20 populations in the state, generally substantially reduced in numbers by habitat destruction (and sometimes also by direct exploitation or disease). These species are also either rare throughout their ranges (fewer than ioo populations total) or disjunct in North Carolina from a main range in a different part of the country or world. Also included are species which may have 20-50 populations in North Carolina, but fewer than 50 populations rangewide. These are species which have the preponderance of their distribution in North Carolina and whose fate depends largely on their conservation here. Also included are many species known to have once occurred in North Carolina but with no known extant occurrences in the state (historical or extirpated species); if these species are relocated in I the state, they are likely to be listed as Endangered or Threatened.

Endangered, Threatened, and Special Concern species of mammals, birds, reptiles, amphibians, freshwater fishes, and freshwater and terrestrial mollusks have legal protection status in North Carolina (Wildlife Resources Commission). The Significantly Rare designation indicates rarity and the need for population monitoring and conservation action. CODE 11STATUS DEFINITION E Endangered "Any native or once -native species of wild animal whose continued existence as a viable component of the State's fauna is determined by the Wildlife Resources Commission to be in jeopardy or any species of wild animal determined to be an 'endangered species' pursuant to the Endangered Species Act." (Article 25 of Chapter 113 of the General Statutes; T 1 Threatened "Any native or once-nativespecies of wild animal which is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range, or one that is designated as a threatened species pursuant to the Endangered Species Act." (Article 25 of 3 Chapter ni of the General Statutes; 1987). P SC 3 Special Concern "Any species of wild animal native or once -native to North Carolina which is determined by the Wildlife Resources Commission to require monitoring but which may be taken under regulations adopted under the provisions of this Article." (Article 2$ of Chapter 113 of the General_ Statutes;1987). _ SR Significantly Rare Any species which has not been listed by the N.C. Wildlife Resources Commission as an Endangered, Threatened, or Special Concern species, but which exists in the state in small numbers and has been determined by the N.C. Natural Heritage Program to need monitoring. (This is a N.C. Natural Heritage Program designation.) Significantly Rare species "peripheral" species, whereby North Carolina lies at the periphery of the species' range (such as Hermit ,include Thrush). The designation also includes marine and estuarine fishes identified as "Vulnerable" by the N.C. State Museum of Biological Sciences (Ross et al.,1988, Endangered, Threatened, and Rare Fauna of North Carolina. Part II. AThreatened, and Rare Fauna of North Carolina. Part II. A EX IlExtirpated A_species which is no longer believed to _occur in the state. P_ µ; Proposed _ Species has been proposed by a Scientific Council as a status (Endangered, Threatened, Special Concern, Watch List, or for De -listing) that is different from the current status, but the status has not yet been adopted by the Wildlife Resources Commission and by the General Assembly as law. In the lists of rare species in this book, these proposed statuses are listed in parentheses below the current status. Only those proposed statuses that are different from the current statuses are listed. — III — FEDERAL STATUS These statuses are designated by the US Fish and Wildlife Service. Federally listed Endangered and Threatened species are protected under the provisions of the Endangered Species Act of 1973, as amended through the tooth Congress. Unless otherwise noted, definitions are taken from the Federal Register, Vol. 56, No. 225, November 21, r991(5o CFR Part 17). CODEIISTATUS D� EFINITION E--7lEndangered A taxon "in danger of extinction throughout all or a significant portion of its range." _ T Threatened A taxon "likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range." EXN Endangered, nonessential The Endangered Species Act permits the reintroduction of endangered animals as "nonessential experimental population. experimental" populations. Such populations, considered nonessential to the survival of the species, are managed with fewer restrictions than populations listed as endangered. T(S/A) Threatened due to Similarity The Endangered Species Act authorizes the treatment of a species (subspecies or population segment) as of Appearance. threatened even though it is not otherwise listed as threatened if. (a) The species so closely resembles in appearance a threatened species that enforcement personnel would have substantial difficulty in differentiating between the listed and unlisted species; (b) the effect of this substantial difficulty is an ! additional threat to a threatened species; and (c) such treatment of an unlisted species will substantially i facilitate the enforcement and further the policy of the Act. The American Alligator has this designation due to similarity of appearance to other rare crocodilians. The Bog Turtle (southern population) has this designation ii due to similarity of appearance to Bog Turtles in the threatened northern population. C Candidate. A taxon under consideration for which there is sufficient information to support listing. This category was formerly designated as a Candidate i (Ci) species. FSC Federal "Species of Concern" (Also called "Species at Risk"). Formerly defined as a taxon under consideration for which there is insufficient information to support listing; formerly designated as a Candidate 2 (C2) PE 1 Proposed Endangered J Species has been proposed for listing as endangered.

The project's location is within lite aboriginal territory of the Cherokee people. This area may have cultural, archaeological, or religious significance to the Eastern Band of Cherokee Indians. Potential cultural resources are subject to damage or destruction from land disturbing activities requiring new ground disturbance, or vegetation manipulation. ,ram Additionally, adverse effects to ethnographic sites, such as traditional Native Amerir:an campsites or burials, can reduce the interpretative or spiritual significance of a site to �+ Tribal and United States culture and history.

Pisgah Wastewatcr Treatment Plant Project scoping.'Dan631, as well, for the fnilowup meeting at JiLRI Eleadtluutcrt to clarify same of the maps and points of this pmposnb. We have reviewed the various alternatives listed in the public notice about this project and have the following comments. It appears that Alternatives "tJ", `A",'F". "0" and "H" are not heing setiouslV considered by RLRI because they will result in little or no effluent quality improvement or cnuldnot he funded, if Ihat assumption is correct, Alternatives "B". "C"- and "F" appear lu be the most. favorable. We ale espeeitdly in ffeuted in the mcmhmm: binreactor package InmIntent ay3lcia. as iL provides superior effluent qualify. However, we have qucsdons regarding each of these pmposals, lamud on our recent research and on conversations with the NC Mplutmtlra of Envirmuncnt and Natural Resources. Alternative B Would this he an CMION l system, whereby, precipitation would not add to the 6ratuleut load? We would favor an enclosed package over an open process. This system would create sludge, which must be processed or removed from the site. How is this currently being done, and how would this sludge be handled under Alternative " I3"9 It appears that this system w•uuld plvvide burcly, if any, improvement over the current systcm. Despite the "low enst we question whether this is really the beet option for — 171 — replacing the existing plant regarding impmved water quality and the best "hang for the bucks". Alterns ive C We like the idea of this alternative from an ecologicid anglc, and would certainly b;, highly yul;pmlivc it the topography was more level and if nu forest canopy would b;, lost. W.C.-am am concerned that the high itltitudc aid steepness of slope may make this proposal impracticable. Further. we are concerned that: construction of such a wellund would very possibly cause significant harm if) the cxixting so►l, p1tint laid wildlife ccalogy in the local amit. There is also v ery• Good chance that sediment from and dwing such construction would snake its wav into Flat Laurcl Creek, especially during storm events. 'tiest. Manabemcnt Practices which --work well in the Piedmont and Cnastal Plirin often fail during such evcnls in the Mountain province. Alternative l+ This alternative looks the most favorable as it significantly improves effluent quidity and is not silmifcantly higher_ in cost. The Town of Highlands Flab apparently has had succas5 with tliis technology and is in the process of upgritoling its membrane bioreactor packaQc capacity. It is our undurstanding that this can be on enclosed or open s�%tem, so wc would again, urge that an enclosed package he utilizcd. Also, apparently tliest, systems have a built-in sludge treatment pnicvss (either as standard equipmeni or as an option'?). This grans to be.a Natter apprt�:irh than havii,g to deal with a separate Mudge removal prnecss. We would urge that ibis be included if that is the vase. In conclusion, we urge BLRY to aive strongconsideration to Alternativc F and implement this if it continues to appear favorable. Alfc believe that the new plant.chould be a significant, rather than a slight, improvement over the existing, ugikg treatment technology. We encourage BLRI to consult with the Town of Highlands And also with Western •n Carolina University/Cullowhee since membrane bioiTaCtor trc:hnnkogy is vo be implemented there, its -,Yell in the near futum.

Pisgah developed area. Parkway officials said that both projects are at the scoping stage and that input is now being sought to help identify issues, areas requiring additional study, and topics to be analyzed in the Environmental Assessment process. Exotic plants are ecologically harmful, frequently displacing or otherwise impairing the function of native plant communities. They can also alter historic landscapes and interfere with visitor use and enjoyment. The existing wastewater treatment plant at Mt. Pisgah is aging and needs to be replaced or upgraded. For more information and to comment on either or both undertakings, visit the National Park Service website: http://t)arkplanning.nps.gov. Select Blue Ridge Parkway from the park dropdown menu and then click on the project that you wish to comment on. Information is also available, and comments made be made by writing to: Superintendent, Blue Ridge Parkway, ATTN: Suzette Molling, 199 Hemphill Knob Road, Asheville, NC 28803. Comments must be postmarked by May 15. Comments are typically treated as a public record and made available for public review. Individuals may request that the National Park Service withhold their name and address from disclosure. Such requests will be honored to the extent allowable by law. —177—
