DIVISION OF ENVIRONMENTAL MANAGEMENT res on Howard, Jr. P.E. WQC# 2926 M C-1 ?J DEPARTMENT OF THE ARMY Wilmington District, Corps of Engineers Post Office Box 1890 Wilmington, North Carolina 28402-1890 Action ID No. 199400693 July 21, 1994 PUBLIC NOTICE THE DEPARTMENT OF THE NAVY, Atlantic Division, Naval Facilities Engineering Command, ATTN: Mr. Thomas C. Horsch, 1510 Gilbert Street, Norfolk Virginia, 23511-2699, has applied for a Department of the Army (DA) permit TO PLACE FILL MATERIAL IN 17.25 ACRES OF WETLANDS ADJACENT TO GREATER SANDY RUN, WEST OF US 17, NEAR VERONA, ONSLOW COUNTY, North Carolina. The following description of the work is taken from data provided by the applicant and from observations made during a site visit by a representative of the Corps of Engineers. Plans submitted with the application show that the proposed work is to occur within the area designated as Range P-949 and is to be a multi-purpose training range for use by the M1/A1 tank, and infantry and aerial assault troops. Construction necessary for the completion of this range will include: a firing area for tanks and infantry; access roads; parking areas; a dining area; a concurrent training station which would accomodate other troops training at the range; a control tower; utility corridors and associated facilities for the range's electrical, water and communications systems; a utility building which will serve as an aid station and command post as well as a facility for the storage and maintenance of equipment associated with the range; a storage area for ammunition; classrooms; instructional bleachers; and loading ramps. The proposed firing range involves the construction of a north and a south dual-track tank trail with a single return track. These trails traverse the range in a roughly east and west direction. There are "spurs" off the trails at varying points and in various alignments. The tanks will travel onto these spurs and will fire at multiple target types which are part of a fully equipped Remote Engagement Targeting System. Only ground to ground fire will occur at this range and only plastic non-explosive projectiles (each weighing about 25 pounds) will be fired. Each track (two per trail) is to be approximately 30 feet wide with drainage swales on either side. The targets will have a bunker constructed around them to protect them from accidental damage. The range will also have access and service roads, which will be approximately 12 feet wide with drainage swales located on either side. -2- Various constraints restrict the functional training portion of the range to a 1,150 acre area. Various designs of the range were reviewed, and wetland impacts were reduced to 17.25 acres. The construction of the tank trails and service roads will result in most of the wetland impacts. Construction of the targets and their bunkers will result in impacts to approximately 0.25 acre of wetlands. The construction of the remaining facilities and structures on the range may result in minor wetland impacts. Based on plans provided by the applicant, it is assumed that, upon completion of the construction associated with these facilities and structures, a majority of the work will be confined to high ground or will result in negligible wetland impacts. Impacts associated with the plastic projectiles landing in wetlands are anticipated to be minimal. Because of the size of the range site, the type of wetlands to be impacted by the project are varied. Impacted areas are primarily scrub/shrub pocosin, with smaller inclusions of forested and emergent wetlands. Some areas have been logged and/or burned at various times in the past. Significant areas have had their hydrological regimes altered by ditches during conversion to loblolly pine plantations. The applicant has redesigned the range in order to avoid wetlands to the maximum extent possible. Various design criteria, as well as the presence of historical resources, dictated the final layout. Where wetlands cannot be avoided, the range has been designed to minimize these impacts. These impacts, totalling 17.25 acres of wetlands, will be mitigated. The mitigation plan is conceptual and under review at this time. Most of the mitigation work will involve either restoration of loblolly pine plantations to fully functioning wetlands or enhancement of hydrologically impaired wetlands. The purpose of the work is to construct a multi-purpose training range for use by both infantry and armored troops. Plans showing the work are included with this public notice. The applicant has determined that the proposed work is consistent with the North Carolina Coastal Zone Management Plan and has submitted this determination to the North Carolina Division of Coastal Management (NCDCM) for their review and concurrence. This proposal shall be reviewed for the applicability of other actions by North Carolina agencies such as: a. The issuance of a Water Quality Certification under Section 401 of the Clean Water Act by the North Carolina Division of Environmental Management (NCDEM). b. The issuance of a permit to dredge and/or fill under North Carolina General Statute 113-229 by the North Carolina Division of Coastal Management (NCDCM). C. The issuance of a permit under the North Carolina Coastal Area Management Act (CAMA) by the North Carolina Division of Coastal Management (NCDCM) or their delegates. M d -3- d. The issuance of an easement to fill or otherwise occupy State-owned submerged land under North Carolina General Statute 143-341(4), 146-6, 146-11, and 146-12 by the North Carolina Department of Administration (NCDA) and the North Carolina Council of State. e. The approval of an Erosion and Sedimentation Control Plan by the Land Quality Section, North Carolina Division of Land Resources (NCDLR), pursuant to the State Sedimentation Pollution Control Act of 1973 (NC G.S. 113 A-50- 66). The requested Department of the Army (DA) permit will be denied if any required State or local authorization and/or certification is denied. No DA permit will be issued until a State coordinated viewpoint is received and reviewed by this agency. Recipients of this notice are encouraged to furnish comments on factors of concern represented by the above agencies directly to the respective agency, with a copy furnished to the Corps of Engineers. This application is being considered pursuant to Section 404 of the Clean Water Act (33 U.S.C. 1344). Any person may request, in writing within the comment period specified in the notice, that a public hearing be held to consider this application. Requests for public hearing shall state, with particularity, the reasons for holding a public hearing. The District Engineer has consulted the latest published version of the National Register of Historic Places for the presence or absence of registered properties, or properties listed as being eligible for inclusion therein, and this site is not registered property or property listed as being eligible for inclusion in the Register. Consultation of the National Register constitutes the extent of cultural resource investigations by the District Engineer, and he is otherwise unaware of the presence of such resources. Presently, unknown archeological, scientific, prehistorical, or historical data may be lost or destroyed by work under the requested permit. The District Engineer, based on available information, is not aware that the proposed activity will affect species, or their critical habitat, designated as endangered or threatened pursuant to the Endangered Species Act of 1973. The decision whether to issue a permit will be based on an evaluation of the probable impacts, including cumulative impacts, of the proposed activity and its intended use on the public interest. Evaluation of the probable impacts which the proposed activity may have on the public interest requires a careful weighing of all those factors which become relevant in each particular case. The benefits which reasonably may be expected to accrue from the proposal must be balanced against its reasonably foreseeable detriments. The decision whether to authorize a proposal, and if so the conditions under which it will be allowed to occur, are therefore determined by the outcome of the general balancing process. That decision should reflect the national concern -4- for both protection and utilization of important resources. All factors which may be relevant to the proposal must be considered including the cumulative effects thereof. Among those are conservation, economics, aesthetics, general environmental concerns, wetlands, cultural values, fish and wildlife values, flood hazards and flood plain values (in accordance with Executive Order 11988), land use, navigation, shore erosion and accretion, recreation, water supply and conservation, water quality, energy needs, safety, food and fiber production, mineral needs, considerations of property ownership, and, in general, the needs and welfare of the people. For activities involving the placement of dredged or fill materials in waters of the United States, a permit will be denied if the discharge that would be authorized by such permit would not comply with the Environmental Protection Agencies' 404(b)(1) guidelines. Subject to the preceding sentence and any other applicable guidelines or criteria, a permit will be granted unless the District Engineer determines that it would be contrary to the public interest. The Corps of Engineers is soliciting comments from the public; Federal, State and local agencies and officials; Indian Tribes and other interested parties in order to consider and evaluate the impacts of this proposed activity. Any comments received will be considered by the Corps of Engineers to determine whether to issue, modify, condition or deny a permit for this proposal. To make this decision, comments are used to assess impacts on endangered species, historic properties, water quality, general environmental effects and the other public interest factors listed above. Comments are used in the preparation of an Environmental Assessment (EA) and/or an Environmental Impact Statement (EIS) pursuant to the National Environmental Policy Act (NEPA). Comments are also used to determine the need for a public hearing and to determine the overall public interest of the proposed activity. Generally, the decision whether to issue this Department of the Army (DA) permit will not be made until the North Carolina Division of Environmental Management (NCDEM) issues, denies, or waives State certification required by Section 401 of the Clean Water Act. The NCDEM considers whether or not the proposed activity will comply with Sections 301, 302, 306, and 307 of the Clean Water Act. The application and this public notice for the Department of the Army (DA) permit serves as application to the NCDEM for certification. Additional information regarding the Clean Water Act certification may be reviewed at the offices of the Environmental Operations Section, North Carolina Division of Environmental Management (NCDEM), Salisbury Street, Archdale Building, Raleigh, North Carolina. Copies of such materials will be furnished to any person requesting copies upon payment of reproduction costs. The North Carolina Division of Environmental Management (NCDEM) plans to take final action in the issuance of the Clean Water Act certification on or after August 12, 1994. e -5- All persons desiring to make comments regarding the application for Clean Water Act certification should do so in writing delivered to the North Carolina Division of Environmental Management (NCDEM), Post Office Box 27687, Raleigh, North Carolina 27611-7687, on or before August 8, 1994, Attention: Mr. John Dorney.

This project will impact forested, scrub-shrub and emergent wetlands with the majority of the impacts being to wet flat type of wetlands. The COE has agreed to process this permit without a completed mitigation proposal which is being developed to compensate for this and other projects. Although I do not think it is a good practice to issue 401 WQC's without an approved mitigation proposal I will concur with Jim Gregson's recommendation (attached) with the following conditions: 1. Mitigation for the impacts to wetlands associated with this project will be included in the "Mitigation Banking Plan for the Greater Sandy Run Mitigation Bank." This banking plan must be approved by the Division of Environmental Management prior to implementation. 2. No additional requests associated with the Greater Sandy Run Area project to impact waters and/or wetlands will be considered by the Division of Environmental Management until the "Mitigation Banking Plan for the Greater Sandy Run Mitigation Bank" has been approved and implemented. ref-ft=401.mem r State of North Carolina Department of Environment, Health and Natural Resources Division of Coastal Management "areA James B.

Dear Colonel Sperberg: The State of North Carolina has completed its review for consistency with the North Carolina Coastal Management Program pursuant to 15 CFR 930 of the above referenced Federal Activity proposed by the Department of the Navy. Based upon our review, we disagree with the Navy's determination that the proposed activity is consistent with the North Carolina Coastal Management Program. The basis for our finding is that the applicant has failed to supply sufficient information (15 CFR 930.39(a) & 15 CFR 930.42(b)). Should the 401 Water (Quality Certification required from the NC Division of Environmental Management be denied, the proposed activity would also be inconsistent with our water quality policies found in 15A NCAC 7M .0800. Information needs include a discussion of impacts related to uses of the facility including onsite and offsite impacts on public trust waters, wildlife habitat and diversity, and neighboring communities. These related use questions were raised in letters from the North Carolina State Clearinghouse dated 6/20/91 and 7/25/91 providing comments on the Final EIS, Proposed Expansion and Realignment of the Marine Corps Base Camp Lejeune (SCH # 91-0819). A copy is attached. In addition, since mitigation is included in the proposal, a detailed mitigation plan is necessary. Finally, more specific plans for all of the proposed construction and land disturbing activities must be provided in order to evaluate the potential impacts to rare plant species (including the Federal and State listed endangered Lysimachia asperulifolia) and "significant" natural areas located during a survey for Camp Lejeune by the NC Natural Heritage Program. An Environmental Assessment entitled "MCON P-949 Multipurpose Training Range, Marine Corps Base Camp Lejeune, North Carolina" has recently been provided to the North Carolina State Clearinghouse for review. A copy was also provided to my office. We anticipate that many of the information needs listed above will be found in the EA once we have had the opportunity to review the document fully. Once we receive the above listed information needs and determine that they are adequate for us to evaluate the consistency of the proposed activity with the North Carolina Coastal Management Program, we will be happy to reconsider our disagreement with the applicant's consistency determination. To this end, we would be happy to meet with representatives of the applicant to discuss information needs in more detail. P.O.

Construction of the MPTR will assist in alleviating the heretofore unmet training area needs which currently constrain the accomplishment of Marine Corps Base Camp Lejeune's mission of providing the training facilities necessary for operational units to maintain combat readiness. Two previous baseline studies, the Special Training Analysis and the Land and Training Area Requirements Study, documented the deficiencies in training areas and facilities at Camp Lejeune. In both of these studies the number and quality of firing ranges and the amount of maneuver area existing on the installation were found to be inadequate or insufficient. See Attached EA.

Thirteen alternatives were proposed and analyzed as potential solutions to existing training area deficiencies. The alternatives involved various combinations of land acquisition, leasing, and realignment of existing facilities. A series of criteria were established to allow comparisons between the alternatives. The criteria included operational requirements (i.e., satisfying military requirements), environmental impacts, and socioeconomic impacts. A complex alternatives analysis process identified the acquisition of the Greater Sandy Run Area (GSRA) as the preferred alternative. The GSRA is a 41,000+ acre tract located in southern Onslow County, adjacent to and west of Marine Corps Base Camp Lejeune. The GSRA tract is bounded on the east and southeast by U.S. Highway 17, by State Road 50 on the southwest and west, and by State Roads 1104, 1105, 1107, and 1119 on the north, excluding some residential holdings (outparcels) along the northern and western perimeter. The GSRA includes a former World War II Army training facility at Camp Davis, located near the town of Holly Ridge. With the exception of two runways, all support facilities at Camp Davis were removed following abandonment. These runways are currently used for helicopter training, and will continue to be used for military training in the future. The GSRA was acquired by the Federal government during 1992-3. Approximately 36,500 acres of the 41,000+ acres were owned by a holding company for International Paper Company (IPC) wh'c;h managed it for silviculture purposes. The remaining acreage acquired consisted of privateiy owned parcels including residences, small businesses, and small farms.

The Greater Sandy Run Pocosin, located within the firing fan of MPTR P-949, is classified as a short (or low) pocosin (see attached Photo 193-51). Low pocosins are distinguished from other peatland community types by the persistent low stature of the shrubby vegetation (less than 1.5 meters tall) and the sparse distribution and low stature of the few trees present. The shrub layer is extremely dense and is composed of fetterbush, titi, greenbriar, and zenobia (Zenobia pulverulenta). Widely scattered, stunted pond pine, loblolly bay, red bay and sweet bay (Magnolia virginica) also occur. The herb layer is generally sparse and consists of Virginia chainfern, broomsedge (Andropogon glomeratus), and p ANALYSIS OF IMPACTS onvisits Personal communication with DCBR personnel, color-infrared h aerial the effects o g aphy, and site (field reconnaissance) were utilized to qualitatively assess artillery fire vegetative cover and surface soil horizon at the DCBR.

Box 5127 Charlottesville, VA 22905 Contract No. N62470-90-D-7696 Delivery Order 0005 I EXECUTIVE SUMMARY 1 1. Description of the Proposed Action This Environmental Assessment addresses the impacts associated with the proposed construction and operation of a Multipurpose Training Range (MPTR) in the northeast quadrant of the recently acquired Greater Sandy Run Area (GSRA) of Marine Corps Base (MCB) Camp Lejeune, North Carolina. The MPTR would be used to teach tank crews the skills needed for engaging stationary and moving targets arranged in tactical arrays, and it would also provide MCB Camp Lejeune a combined tank firing range and maneuver area in which tanks could train in conjunction with dismounted infantry against stationary and moving targetry. This type of range is a standardized design and it is used to certify that the individual tank crew is qualified to begin collective, live-fire training at the unit (section or platoon) level. It is the critical transition between individual and unit proficiency. 2. Alternatives Considered i f h d MPTR or t e propose were tes In the preparation of this EA, three potential GSRA s analyzed, in addition to the possibility of siting it within the existing MCB Camp Lejeune range structure. For operational and environmental reasons (including the inability of MCB Camp Lejeune locations to provide the required distance-to-target for main tank gun crew qualification, conflicts with the GSRA Master Development Plan, and wetlands impacts), the two potential southern GSRA sites and a MCB Camp Lejeune existing range location were dismissed. Constructing the MPTR in the northeastern GSRA became the Proposed Action; the remaining alternative considered was No Action. This document focuses on these two alternatives. An analysis of Marine Corps training shortfalls and requirements, and thirteen alternative solutions to the identified training needs at MCB Camp Lejeune is contained in a Final Environmental Impact Statement for the Proposed Expansion and Realignment of Marine Corps Base Camp Lejeune, North Carolina, which was completed in May 1991 (referred to herein as the Acquisition EIS). That EIS reviewed the expected overall environmental and socioeconomic impacts of the acquisition, development, and use of the GSRA; however, it was recognized that additional specific environmental analysis would be required for the various anticipated projects as the GSRA was developed for Marine Corps training purposes. The Proposed Action Alternative calls for the construction of a MPTR in the northeast quadrant of the GSRA. The siting of the MPTR in this location is based primarily upon the scarcity elsewhere in the GSRA of high ground and trafficable soils needed for the tank maneuver trails, coupled with the requirement for a large surface danger zone (SDZ). Additionally, long range development plans for the entire GSRA, including various other contemplated range requirements, SDZ needs, and safety factors, were analyzed. The proposed MPTR would consist of two maneuver firing tank trails situated within a 740 acre rectangle containing stationary targets, moving targets, and defilade positions. Crews scheduled for training would bring tanks (usually two per training evolution) to the MPTR by truck from Camp Lejeune. A standard training evolution would consist of two tanks and 22 personnel for a two day training period. The range would be used for tank training approximately every other week (26 weeks per year); additionally, infantry would use the range for small arms training one day per week all year. Support facilities for the MPTR would be situated in the vicinity of the base line of the maneuver area, and would include a control tower, operations/storage building, field service bathroom, covered bleacher enclosure for troop instruction, and a large crushed rock vehicle holding area. Initial access to the range would be over existing roadways, some of which would require resurfacing. No tank washing would be performed at the MPTR, and only operationally required maintenance, to include required emergency maintenance, would be performed at the MPTR. A SDZ for spent projectiles would radiate to the west of the range in the north-central GSRA. This SDZ would cover approximately 5,900 acres. Only non-explosive steel or copper jacketed ordnance would be used on the proposed MPTR so that the SDZ would not be "dudded," and no long term unexploded ordnance and/or contamination hazards would be created. Although not within the GSRA boundary, a proposed borrow pit for construction fill located within the Verona Loop area of MCB Camp Lejeune has been identified, and fill dirt (estimated 70,580 cubic yards) would be brought to the GSRA for construction of the proposed MPTR. The site for the proposed borrow pit was chosen from among eight sites identified within an area of MCB Camp Lejeune between the New River and U.S. Highway 17. Eight criteria were applied in the selection of the borrow pit: Quality and quantity of fill material; environmental impact on wetlands; environmental impact on endangered and threatened species; conflicts with remedial investigation sites; impact on archaeological/historic sites; conflict with land use plans; cost per cubic yard of fill; and site accessibility. The No Action Alternative would continue the status quo in the face of increasing training pressure from the new Marine Battle Skills Training regimen and the changing requirements of newer weaponry. MCB Camp Lejeune's documented shortfalls in current maneuver area, identified in the LATAR Study as insufficient in size and of poor quality, would be perpetuated. In order to qualify tank crews, the current practice of sending personnel to off-base training facilities such as Fort Knox, Kentucky would continue, as would the inefficiency and waste in training time, complications arising from inter-service scheduling of heavily utilized ranges, and added monetary expense. Based on a comparative analysis of these alternatives with respect to operational and environmental criteria, the Proposed Action Alternative is considered the preferred alternative. A detailed discussion of both the Proposed Action alternative and the No- Action alternative is provided in Section 2.0, Alternatives. 3. Summary of Environmental Impacts The construction, operation, and maintenance of the proposed MPTR would have only minor impacts on the environment. The majority of the GSRA tract was previously owned and managed by a paper company for timber production, and hence most of the natural communities have been altered to one degree or another. The construction of the proposed MPTR would not adversely affect surrounding land use, as the range would be wholly located within the GSRA and is consistent with plans for the property, as evaluated in the Acquisition EIS. 2 The soils within the proposed MPTR maneuver area which would be affected by training operations are poorly drained, sandy soils. Erosion potential would require mitigation programs to avoid siltation of waterways and wetlands, but erosion impacts would be localized due to the flat terrain and sluggish water flow. For this reason any mitigation measures should be relatively easy to institute. As an example, during construction phases, temporary ground cover and silt fence would be used to contain erosion. For long term control, vegetative buffer zones, and possibly berms to direct or channel runoff away from sensitive areas, would be included in the range design. Proper water quality standards will be maintained. Requisite State construction permits, wastewater permits, stormwater permits and water quality certification will be obtained for both construction and operation of the proposed range. Potential siltation of surface waters or wetlands during construction will be controlled by strict adherence to erosion and sedimentation control measures. A concern, as with any firing range, is the possibility of fire. Peat comprises a large portion of the soil composition of the pocosin areas of the GSRA over which the SDZ fan would lie, thereby adding increased dangers beyond those normally associated only with vegetative cover. The use of non-explosive ordnance is planned for proposed MPTR operations, thereby reducing the risk of fire. However, other incendiary devices (smoke grenades, booby-trap simulators, hand held illumination) would be used on the range. Fire management efforts would include increasing periodic controlled burns as part of MCB Camp Lejeune's Natural Resource Management program, increasing fire control personnel from nine to seventeen, and purchasing additional fire control equipment including four more low pressure tractor and plow units, four portable bridges and four bridge trucks . The long range plans for the GSRA development include three 125 foot observation towers in the northern GSRA and a perimeter road which, if constructed, would provide easier and quicker access to fire locations as well as providing a fire break around the entire GSRA. A revised Fire Control Plan for MCB Camp Lejeune (which includes the GSRA) has been prepared. Mutual assistance agreements with both the U.S. Forest Service and the State of North Carolina have been executed. Additionally, in an emergency situation, the manpower pool for firefighters at MCB Camp Lejeune is significant. In early 1994, remote sensing of aerial photography, soil survey, and topography, Geographic Information System (GIS), and Global Positioning System (GPS) technologies, in conjunction with field surveys, were used to delineate wetland boundaries within a rectangular area comprising 1150 acres in the northeast quadrant of the GSRA, and within which the proposed MPTR (encompassing a rectangle of 740 acres) would be sited. The delineation study revealed that within the 1150 acre survey area there were 443 acres of jurisdictional wetlands. An analysis of this 1150 acre rectangle was conducted to determine the best location and design for a 740 acre MPTR. From among several alternatives, a site and design were chosen which would minimize wetland impacts. The Corps of Engineers estimates that there will be approximately 25 acres of wetland impacts associated with the preferred MPTR range siting and design (including access road to the range and support facility construction). A permit from the Corps of Engineers would be required, and mitigation would be expected. To address the mitigation requirements associated with the MPTR, and in preparation for further GSRA development, a conceptual wetland mitigation plan has been developed 3 which is based on the creation of a Wetlands Mitigation Bank within the GSRA. Wetlands that have been altered and disturbed as a result of previous timber practices have been selected throughout the GSRA for wetland restoration. These drained wetlands are historic pond pine pocosin wetlands that have been converted to plantation pine through mechanized silviculture practices, including implementation of drainage ditches and bedding planes to plant stands of loblolly pine. A strategic hydrologic monitoring plan has been implemented throughout these drained wetland areas that have been converted to pine plantation. In those areas in which wetland hydrology is found not to be present, a site-specific wetland restoration plan will be developed. Restoration of wetland hydrology will be accomplished by a combination of plugging ditches, which will eliminate the wetland drain, and by cutting the planted pine, which will eliminate the hydrologic pump. It is anticipated that these actions will result in the restoration of wetland hydrology. The Corps of Engineers has provided recommendations concerning wetlands mitigation and the development of a wetlands mitigation banking program. For the initial banking effort, an extensively drained 800+ acre site underlain with hydric soil has been identified in the southeastern quadrant of the GSRA as a potential area for the wetlands mitigation bank. Studies are being conducted to determine the potential wetland restoration acreage within the bank. The Marine Corps plans to mitigate wetland impacts from the proposed MPTR at a minimum of two acres to one ratio through the use of the wetlands mitigation bank. Based on experience elsewhere, a concern associated with the operation of the proposed MPTR is that tank and infantry training have the potential for erosion and sedimentation impacts in adjacent wetlands. Mitigation measures, which could include vegetative buffer zones, silt fences, check dams and sedimentation basins, are noted in the present project design, and a comprehensive erosion control plan would be required as part of the State stormwater certification and construction permit process. The majority of impacts to vegetation would result from the clearing and use of tank trails and targetry in the maneuver area. For the installation of targets and line-of- sight range openings, vegetation would be maintained near ground level in an early-to- mid successional state, depending on weapon sighting requirements. Maintaining the vegetation in this state would be accomplished through controlled burns, bushhogging, and/or hand clearing (as required). Converting the proposed MPTR from pine plantation to early-to-mid successional vegetation for construction and operation of the MPTR would increase habitat diversity in the area. Tracked vehicles are not expected to leave the tank trails, thereby minimizing impacts upon vegetation within the proposed MPTR maneuver area. A 1993 North Carolina Natural Heritage Program (NHP) inventory of the entire GSRA identified 26 plant species recognized as rare at the Federal or State level (with varying degrees of rarity and protection). Fifteen of those plant species were located in the northern GSRA, within the potential sphere of impacts of the proposed MPTR. Of these rare plants, only one - the rough-leaved loosestrife - is Federally protected as Endangered. Three others are Candidates for Federal protection. The .$= protected species ?,? -Iude three listed as Endangered, and the remainder falling into various Candidai- -•,r protection categories. Rare plants which could arguably be affected by the proposec "TR are generally located in two areas: the extreme western area of the SDZ (the rougi,-:,? aved loosestrife is located in that area); and in the maneuver and support facility areas, generally along roads and the powerline right-of-way. Any potential 4 effects to rare plants in the western SDZ area are considered negligible due to the distance involved, and because of the use of non-explosive ordnance. The U.S. Fish and Wildlife Service (USFWS) has been consulted concerning the rough-leaved loosestrife (the only Federally listed endangered species) and concurs with that belief. Impacts to the $tate protected, and Federal Candidate plant species in the maneuver and support facility area could result from construction and use of the proposed MPTR. As required, consultation with the U.S. Fish and Wildlife Service would be undertaken to determine actual impacts and potential mitigation measures. The main impacts upon wildlife from MPTR operations would be the alteration of habitat and stress associated with increased human presence. Those impacts are not expected to affect any large communities. In fact, the early-to-mid successional habitat created by the construction and operation of the proposed range through brush clearing and maintenance of open areas in the target and maneuver area would increase overall biodiversity within the GSRA. The current animal populations in the vicinity of the proposed MPTR are considered only remnants of the native fauna as a result of the previous timber operations and maintenance of a pine monoculture. No Federally protected wildlife were located within the GSRA, but two $tate rare birds (both currently Candidates for Federal listing) and one State endangered mammal were located in the southern GSRA, remote from the proposed MPTR and considered outside the sphere of impacts associated with the proposed MPTR. There would be no permanent impact on the local human population associated with the proposed MPTR. Construction of the range and associated support facilities would provide some temporary construction employment. The budget for the proposed range construction is $5.3 million and $1.3 million for target installation. The annual operation and maintenance budget for the proposed range is expected to be $160,000, and would include four full-time civilian employees. The MPTR would receive electric power from the existing overhead 12.47 KV transmission line, and telephone service would be provided by extending the fiber-optic line that now runs from Marine Corps Air Station (MCAS) New River to the Verona Loop area of MCB Camp Lejeune. Water is planned to be provided by construction of a well, and a treatment system would also be constructed on the proposed MPTR site. Wastewater is planned to be handled by construction of a leach field, however, the soils in the area may preclude securing a construction permit. An alternative sewage system, such as chemical toilets or sewage hookup to MCB Camp Lejeune may be required. Traffic impacts associated with the proposed MPTR would be greatest during construction of the range. Large amounts of fill and other construction material would be required. This would include an estimated 70,580 cubic yards of fill which could entail 6,000-10,000 dump truck loads. Use of signage, flagmen, and scheduling would assist in mitigating the impacts of bringing construction material from outside the GSRA (including the main impact associated with trucks crossing U.S. Highway 17 from the Verona Loop borrow pit). After construction, operation of the MPTR would have minimal traffic impacts. In the long term, direct access via underpasses from MCB Camp Lejeune would significantly reduce traffic impacts. An area of Restricted Airspace over the GSRA would be required for range operation. An application for a 55.5 square mile, joint/intermittent use, stratified Restricted Airspace covering the GSRA up to an altitude of 17,999 feet above mean sea level (MSL) 5 has been submitted to the Federal Aviation Administration (FAA). The substantive restrictions and mitigation measures contained in the application were developed with the assistance of the FAA. The Restricted Airspace, as requested, would be composed of three vertical strata and the GSRA would be divided into two sectors (north and south) to provide greater flexibility and allow for less impact on the use of the V-139 Airway. The three proposed strata are: surface to 6,999 feet MSL; 7,000 to 9,999 feet MSL; and 10,000 to 17,999 feet MSL. For safe operation, the proposed MPTR would only require the lowest stratification of airspace (0 to 6,999 feet MSL). The airspace restriction would be in place from ground level to 6,999 feet MSL from 0600 to 1800, Monday through Friday. If MCB Camp Lejeune should require additional restricted airspace strata, or additional times beyond the 0600 to 1800, Monday through Friday, it would have to be scheduled at least 30 days in advance with the FAA to allow for the publication of a Notice to Airmen (NOTAM). Mitigation measures to accommodate any aircraft which would not be able to climb above the proposed MPTR restricted airspace level (normally 6,999 feet MSL) will include requiring interruption of the GSRA airspace restriction, or in the alternative, interrupting training activities at other ranges and allowing air traffic to pass through MCB Camp Lejeune restricted airspace to the east. A noise impact analysis of planned range operations associated with the proposed MPTR was conducted by the U.S. Army Environmental Hygiene Agency, Bio-Acoustics Division, Aberdeen Proving Ground, Md. The noise impact contours indicate that the proposed MPTR operations will not create unacceptable noise impacts outside the GSRA. In cooperation with the North Carolina State Historical Preservation Officer (SHPO), MCB Camp Lejeune classified soils within the GSRA according to their potential to contain significant cultural resources. Approximately 70 to 80 percent of the soils were found to have a low probability, with the remaining 20 to 30 percent having moderate to high probability. It was agreed that archaeological survey would only be required for the moderate to high probability areas. Within the general vicinity of the proposed MPTR maneuver and support facility area, all moderate to high probability soils were surveyed using 30 meter transects with test units placed at 30 meter intervals. As a result of this survey, six sites were discovered to the north of the proposed MPTR maneuver/support facility area. These six sites appear to be eligible for nomination to the National Register of Historic Places, but are far enough away that they will not be affected by the construction or operation of the proposed MPTR. It has been agreed between MCB Camp Lejeune and the SHPO that further testing and study of the six sites, which appear to contain intact prehistoric cultural remains which may yield information important to the prehistory of the Southern Coastal Plain region, should be delayed until additional surveys of other tracts within the GSRA are completed so that discoveries can be analyzed within a larger regional context. However, in order to avoid inadvertent or accidental damage during the construction phase of the proposed MPTR, the six sites would be marked in the field prior to the commencement of any construction activities. Because the Marine Corps real estate acquisition was not complete within the GSRA at the time of the cultural resource survey of the proposed MPTR mane ever/support facility area, the extreme western portion of the SDZ was not surveyed although the soils would indicate a reasonable potential for cultural resources. Now that acquisition is complete, archeological surveys in that area, which is far removed from the proposed 6 94 1 i J l . n u y 9 maneuver/support facility area of the MPTR, are scheduled to commence Any discoveries will be coordinated with the SHPO, although no impacts from the construction or operation of the proposed MPTR are foreseen. With regard to cultural resources within the GSRA in general, and the overall plans for military development within the GSRA, a programmatic agreement is being negotiated among the SHPO, the Advisory Council on Historic Preservation, and MCB Camp Lejeune. The programmatic agreement will provide that prior to any actual ground-breaking activities associated with GSRA development, proper cultural resource surveys will be completed in those areas of moderate to high potential for cultural resources which may be impacted by planned development. The results of these future surveys will be coordinated with the SHPO prior to the construction of any proposed ranges or facilities. A proposed borrow pit site associated with the construction of the proposed MPTR is located in the Verona Loop area of MCB Camp Lejeune. This 55 acre area was subjected to archaeological survey and no sites were found. t li 171 t 11 TABLE OF CONTENTS 1.0 Purpose and Need for Proposed Action 1.1 1.2 Description of the Proposed Action .................................................

The MPTR would be designed to teach tank crews the skills needed for engaging stationary and moving targets arranged in tactical arrays, and it would also provide MCB Camp Lejeune a combined tank firing range and maneuver area in which tanks could train in conjunction with dismounted infantry against stationary and moving targetry. This type of range is a standardized design and it is used to certify that an individual tank crew is qualified to begin collective, live-fire training at the unit (section or platoon) level. It is the critical transition between individual and unit proficiency. It should be noted that the Greater Sandy Run Area (GSRA) is now an integral part of MCB Camp Lejeune, and in the normal course of events the term "MCB Camp Lejeune" includes the recent property acquisition. However, for ease of reference and to sharpen focus in the following environmental analysis, this Environmental Assessment often segregates and discusses the GSRA as though it were a separate entity. 1.2 Project Background 1.2.1 Project History The fundamental task of MCB Camp Lejeune is to provide the necessary facilities for 2nd Marine Expeditionary Force organizations to maintain their combat readiness. In the period between its founding in 1941 and 1992, MCB Camp Lejeune's land holdings remained virtually unchanged. The Marine Corps' mission, organization and weapons systems, however, underwent substantial change during this period, reflecting requirements of the modern battlefield. Because of significant growth in technical training requirements (due to complexity/lethality of modern weapons systems, highly maneuverable forces, and high speed aircraft), MCB Camp Lejeune's available facilities were not able to satisfy many basic Fleet Marine Force training needs by as early as the mid-1970's. l d L C ejeune, coup e amp Recently evolved changes in training, Marine Corps-wide and at with existing constraints to land use, accentuated deficiencies in training area requirements. A new training regimen that focuses on the individual infantryman, known as Marine Battle Skills Training or MBST, was developed in response to the changing requirements of the modern battlefield. Camp Lejeune is one of two sites in the United States where the second phase of MBST, Marine Combat Training, is conducted. The implementation of the new MBST training regimen has resulted in an additional 22,000 Marines training on Camp Lejeune facilities annually. A Special Training Analysis (STA) was conducted in 1985, followed in 1988 by a Land and Training Area Requirements Study (LATAR), and in 1989 by a MCB Camp Lejeune Training Facility Requirement Study. All identified significant training facility These studies concluded that existing firing ranges Lejeune deficiencies at MCB Cam . p 1-1 were inadequate and that land remaining for maneuver areas was insufficient on MCB Camp Lejeune to support the combat readiness mission. The most critical training deficiency was the lack of adequate maneuver space and the limitations imposed on existing maneuver training by environmental restrictions. At present, in order to qualify for unit-sized tank operations, tank crews are sent to train on U.S. Army ranges at Fort Knox, Kentucky. Because of range scheduling problems and the extremely high costs involved in off-base training, each Battalion receives only one qualification per year instead of the two which are called for by training plans. As a result of the identified land and training area deficiencies, MCB Camp Lejeune officials began to examine alternative solutions to rectify the situation. Alternatives evaluated ranged from maintaining the status quo to the extreme option of relocating MCB Camp Lejeune altogether. Alternatives which considered establishment of additional ranges and maneuver areas on existing Marine Corps-owned property at MCB Camp Lejeune were unattainable due to environmental and man-made constraints (which rendered much undeveloped area of the base unusable). Eventually, base officials determined that acquisition of a contiguous area of land was the best alternative for MCB Camp Lejeune. Consequently, the Department of the Navy programmed the purchase of a 41,100 acre tract of land, known as the Greater Sandy Run Area (GSRA), for MCB Camp Lejeune in 1991. Congress approved funds for the purchase of the property in Fiscal Year 1992. 1.2.2 Description of the GSRA The GSRA is an approximately 41,100 MCB Camp Lejeune complex in central 1-2).

Historically called the Great Sandy Run Pocosin, it is from this biotic community that the parcel name Greater Sandy Run Area is derived. 1.2.3 The GSRA Environmental Review Process A thorough analysis of alternatives has been accomplished regarding the overall training needs and concerns facing the Marine Corps and MCB Camp Lejeune and is contained in a Final Environmental Impact Statement for the Proposed Expansion and Realignment of Marine Corps Base, Camp Lejeune. The EIS was completed in May, 1991 and this document is hereinafter referred to as the "Acquisition EIS". The Acquisition EIS addresses in depth the need for more training facilities, and in particular, the development and/or acquisition of additional maneuver areas. It includes an analysis of training requirements and the rationale and constraints surrounding the siting of 1-2 I-J 11 [7 L s t ¦ r r... ...r?,,.. d `•` V .Jj m m •m?/ d ; o r f r _ ro •C \ j / 3 ???•J cz d w lr ! a) :•3 . \.

Qaw L) Q M ul cU M ?C) W I- N J O I various training ranges in conjunction with training facility realignment options on MCB Camp Lejeune. Thirteen alternatives were proposed and analyzed as potential solutions to existing training needs at MCB Camp Lejeune. These alternatives ranged in magnitude and impact from maintaining the status quo (No Action), to increasing off- base training, to the extreme of relocating MCB Camp Lejeune. Several of the proposals analyzed included various combinations of realignment of existing ranges and/or the purchase of up to 79,000 acres of land. The alternatives analysis contained in the Acquisition EIS included evaluation of the operational, environmental, and socioeconomic impacts of proposed development alternatives for the GSRA. The Record of Decision (ROD), which was published in the Federal Register on October 3, 1991, announced the Department of the Navy's decision to acquire the parcels of land adjacent to MCB Camp Lejeune now known as the GSRA. The ROD discussed the planned management and use of the GSRA, and reviewed the expected environmental and socioeconomic impacts of the Marine Corps' acquisition, development, and use of the property. Although the Acquisition EIS discussed impacts of the GSRA's development and use, the need to perform further environmental review of "specific proposals to site and operate maneuver areas, firing ranges, weapons systems, and impact areas" as they are developed was recognized in the ROD (Department of the Navy 1991). This Environmental Assessment addressing the proposal to build and operate a MPTR in the GSRA tract is the next logical step in the environmental review process addressing the development and use of the GSRA. Although a discussion of a MPTR was not specifically included in the preliminary land use concept for the GSRA (as outlined in the Acquisition EIS), such a range is entirely consistent with the overall development plan for the property. E 11 G t 171 1-5 V 1 2.0 ALTERNATIVES 1 2.1 Description of Alternatives This section presents a discussion of the Proposed Action of constructing a Multipurpose Training Range (MPTR) in the northeast sector of the GSRA (and supporting factors which argue against other locations within the GSRA or elsewhere on MCB Camp Lejeune), and the No Action alternative of continuing off-base training for tank crew qualification. The alternatives analysis presented in this document is narrowed somewhat because the Acquisition EIS evaluated a broad range of locational and operational alternatives leading to the purchase of the GSRA. That document (Draft EIS (DEIS), 1989, Vol. I, Sec. II) contains a thorough analysis of the alternatives considered, including potential realignment of ranges within MCB Camp Lejeune, and various combinations of range realignment and base expansion options. Within the GSRA, the potential locational alternatives are restricted by physical constraints, additional planned range development projects, safety and environmental factors, and operational requirements. In terms of the No Action Alternative, which is essentially the continuation of the status quo, the Acquisition EIS discussed the operational, environmental, and socioeconomic impacts of continued use of existing ranges at MCB Camp Lejeune and other military bases in the region. The analysis of the impacts of the No Action Alternative will be briefly summarized in this document; however, the reader again is referred to the Acquisition EIS for an extensive evaluation of the impacts of No Action (DEIS, 1989, Vol. I, Sec. II). 2.1.1 Alternatives Evaluated and Discarded As noted above, the driving force behind the acquisition of the GSRA was to provide a partial solution to the long term and increasing training shortfalls faced by the Marine Corps, particularly with regard to maneuver areas. Attempts were made to find a suitable location for a MPTR on MCB Camp Lejeune, and realignment studies were conducted (LATAR, STA). However, natural and man-made constraints precluded the siting of the proposed MPTR within the established range structure on MCB Camp Lejeune. Prior to the purchase of GSRA, it was calculated that 45 percent of existing MCB Camp Lejeune land was inadequate for training purposes due to some type of constraint (STA). The LATAR Study not only identified training shortfalls, but also grappled with range realignment on MCB Camp Lejeune. A central theme throughout the LATAR study is that additional maneuver area is required and that the importance of base expansion could not be overemphasized. Natural features of the land on MCB Camp Lejeune which restrict its use include general topography, soil type, wetland systems, floodplains, and ecological communities unique in flora and/or fauna. The principal topographic limitations are open water bodies, including the New River, its tributaries, and the Atlantic Intracoastal Waterway (AIW), which comprise over 25 percent of the total area of the installation. Steeply sloped drainage basins also negatively impact on suitability for maneuver training. Of the 31 soil types documented on MCB Camp Lejeune, a majority are classified as moderate to severely limiting with respect to trafficability by heavy vehicles. Wetland biotic communities are protected from development (or require mitigation measures entailing further land set-asides), and these wetland communities are dispersed throughout MCB Camp Lejeune in association with the floodplains of the New River and its tributaries. 2-1 Finally, the presence of endangered species, such as the red-cockaded woodpecker, also represents a real constraint to land utilization. MCB Camp Lejeune (excluding the GSRA and MCAS New River) covers approximately 106,300 acres. The total acreage of open water areas on MCB Camp Lejeune, including associated floodplains and wetlands, is some 25,200 acres; the total acreage affected by endangered species constraints is approximately 3,200 acres (DEIS, 1989, Vol. I, Sec. 1). The principal man-made constraints affecting the inability to site the proposed MPTR on MCB Camp Lejeune center on the large land area required for a tank maneuver area and targetry, and the surface danger zone (SDZ) fan associated with live fire exercises. Additionally, the very nature of the modern M1A1 tank and its equipment, particularly its laser range finder, presented a serious impediment to locating the MPTR on MCB Camp Lejeune due to congestion and human encroachment. While a tank maneuver area is currently located on MCB Camp Lejeune, the impact area for live fire is in the Atlantic Ocean, requiring firing across the Atlantic Intracoastal Waterway (AIW). For firing exercises, use of the AIW must be interrupted or training schedules interrupted or curtailed. But, of primary importance, the longest main tank gun shot that can be accommodated on that range is 1200 meters; whereas, the minimum shot distance required for tank gun crew qualification is 2500 meters (Training and Operations Div., MCB Camp Lejeune). Additionally, training in the use of the laser range finders presented a problem because of the danger to unprotected eyes of individuals potentially viewing the direct laser beam or the reflection from a flat surface, such as water. (This hazard has been recently reduced by the Marine Corps' adoption of the ESSLR Eye Safe Laser filter.) The combination of civilian encroachment (including boaters in the AIW), and the amount of open water on MCB Camp Lejeune, in conjunction with the natural constraints which impose land area limitations noted above, presented insurmountable problems for the siting of a standard design MPTR on MCB Camp Lejeune. Three alternative sites within the GSRA were also evaluated. In addition to the proposed location for the MPTR in the northeastern quadrant of the GSRA, two sites in the southern sector also provide the requisite land area for the MPTR and allow for the needed SDZ fan. The alternative site options were selected based upon the presence of areas of higher ground to accommodate the tank maneuver trails, and also to avoid, as much as possible, wetland impacts. One is located generally in the south central GSRA on the western side of the tract, aligned from southwest to northeast. The SDZ radiates northeastward. The second is located generally in the south central GSRA on the eastern side of the tract, oriented from the southeast to the northwest. The SDZ radiates generally to the northwest (Figure 2-1). The proposed location in the northeast quadrant of GSRA was chosen over the other two for both environmental and operational reasons. The discarded location on the southwestern side of the tract (Option #1, Figure 2-1) involves larger wetlands impacts and operational problems not associated with the currently proposed location. Although the area considered generally provides some high ground for the tank maneuver trails, the impacts to wetlands associated with Shelter Swamp Creek are estimated to be significantly greater than the wetlands impacts (approximately 25 acres) in the northern site. Additionally, the draft GSRA Master Development Plan anticipates another multipurpose maneuver range called a Multipurpose Range Complex (MPRC), which, because of its size and operational design, can only be situated in the south central GSRA 2-2 suoqujodp pue 6uiuium1 'ounolol ckuep OON! :oajnog SNOIldO N0113313S 311S dldW HlIM V38V Nna AONVS UMME19 3Hl s,o,ow 000'4 0 L-z 3anow = a= 0 a m a it w a w a a a w a w a a 70 Q 'o Y cu _ -19 a) N .

The Acquisition EIS contains an in- depth discussion of the operational needs and maneuver area shortfalls that resulted in the purchase of the GSRA. That analysis will not be repeated in this document. The operational criteria utilized in this section to evaluate the Proposed Action alternative and the No Action alternative proceed from the prior determination of need for additional maneuver area training facilities such as the proposed MPTR. 2.2.1 Operational Criteria The following Operational Criteria examine the degree to which the alternatives meet training requirements and other military considerations: • Firing range requirements; • Maneuver area requirements; Surface Danger Zone (SDZ) requirements; Range support facility requirements; and • Range access requirements. Ability of Alternative 1 (Proposed Action) to Satisfy Operational Requirements - The Proposed Action, constructing a MPTR in the northeast quadrant f h o t e GSRA, would meet the listed operational criteria and would provide a significant contribution to alleviating training shortfalls associated with MCB Camp Lejeune. As previously noted, various training studies (STA, LATAR) concluded that the most critical training deficiency at MCB Camp Lejeune was the lack of adequate maneuver space and the limitations imposed on maneuver training by environmental restrictions. The standardized design of the MPTR would provide critical firing and maneuver training and tank crew qualification opportunities heretofore not available on MCB Camp Lejeune. Ability of Alternative 2 (No Action) To Satisfy Operational Requirements - The "No Action" alternative fails to satisfy any documented training shortfalls at MCB Camp Lejeune and is therefore considered an unacceptable alternative from an operational point of view. 2.2.2 Environmental Criteria Environmental criteria examine the natural resource issues, regulatory concerns, and socioeconomic factors associated with the alternatives. The environmental criteria which will be considered include: • Water Quality; • Fire Suppression and Fire Control; • Natural Resources (including Exemplary Natural Areas, Vegetation, Wildlife, Wetlands); • Cultural Resources; • Airspace Requirements; • Noise; • Traffic; and 2-11 • Public Access and Safety. 2.2.3 Environmental Impacts of Alternative 1 (Proposed Action) Water Quality Water quality issues of concern during construction and operation of the proposed MPTR include stormwater runoff and sewage treatment and/or disposal. Stormwater runoff would be affected by land clearing, and road and facility construction. The operation of tanks on roads and tank trails could also contribute to degradation of stormwater quality. However, these potentially negative impacts would be neutralized through standard mitigation measures. Because only non-explosive ordnance would be used on the range, any potential effects on surface water from spent ordnance, either in the target areas or in the SDZ, is expected to be negligible. A borrow pit for construction fill would be required for the construction of the proposed MPTR and there is a potential for localized impacts on water quality from stormwater runoff when the borrow pit is active. However, potential impacts related to the borrow pit operation are also susceptible to mitigation measures. Sewage disposal for head facilities in the MPTR support area has been planned using a septic tank and leach field. There exists the potential for problems in implementing this plan, due both to the existing high water table and the predominant soil types. Soils that exist in the general area where sanitation facilities are to be located have been typified as poorly drained and limiting development (Onslow County Planning Dept., 1992, Land Use Plan, Sec. IG). The potential exists that portable toilets or a direct connection to the Camp Lejeune sewer system would be necessary for the proposed MPTR if local conditions preclude obtaining construction permits. Fire Suppression and Fire Control Fire suppression and control are important issues in the GSRA. Although no explosive ordnance will be used at the proposed MPTR, normal training activities, including the use of incendiary devices (smoke grenades, booby-trap simulators, hand-held illumination), would result in an increased fire potential in the GSRA. A new Fire Control Plan for MCB Camp Lejeune (which now includes fire prevention and response measures for the recently acquired GSRA) has been prepared. Separate Memoranda of Understanding have been executed between MCB Camp Lejeune and the State of North Carolina and the US Forest Service. In the event of fire, the signatories pledge mutual assistance, if able to respond. Natural Resources (Exemplary Natural Areas, Vegetation, Wildlife, Wetlands) The State of North Carolina, Department of Environment, Health, and Natural Resources (DEHNR), Natural Heritage Program (NHP) has prepared a comprehensive inventory of rare species, natural communities, and critical habitats of the entire GSRA (NHP Inventory, Jul., 1993). Few high quality, little-disturbed natural communities remain in the GSRA as a result of the previous timber operations. However, three exemplary natural areas within the GSRA of sufficient size and quality to be recommended for special attention and protection were identified. These areas are the Pocosin Basins (north and south), an area in the vicinity of Padgett Swamp Road, and an area in the vicinity of the South Bay Road (Figure 2-2). Portions of the northern pocosin and the 2-12 t Padgett Swamp Road area fall within the SDZ fan associated with the proposed MPTR, however any measurable impact or damage in these areas from training operations at the proposed MPTR, including damage from spent projectiles, is considered extremely remote. The NHP Inventory identified a total of three animal species and 26 plant species in the GSRA considered rare by Federal or State authorities. Of the 29 rare plants and animals, six species have Federal designations, but only one (the rough-leaved loosestrife (Lysimachia asperulaefolia)) is protected as a Federal Endangered species. This plant has been identified in the northwest GSRA in the vicinity of Padgett Swamp road. The other species of Federal concern are Candidate species (Level 2 - species for which there is some evidence of vulnerability, but for which there are not enough data to support listing as Endangered or Threatened at this time). Of the 29 State rare species, fifteen (all plants) were identified in the northern GSRA. Nine are considered to be located within the sphere of impacts associated with the proposed MPTR. Three of the State listed species are categorized as State Endangered; the remainder are designated at varying levels of rarity as Candidates for protection. The U.S. Fish and Wildlife Service (USFWS letter of 15 November 1993) has concurred in the opinion that it is unlikely that the development or operation of the MPTR would have a negative impact on any Federally listed endangered species, as the rough-leaved loosestrife locations are in the Padgett Swamp Road area at the western extreme of the proposed SDZ fan. However, several of the Federal Candidate plant species are located in the vicinity of the proposed MPTR maneuver and support facility area, particularly along roads and in the eastern powerline corridor. The character of some of the vegetative communities within the proposed MPTR maneuver area and support facility area would be altered by construction and operation of the range. MCB Camp Lejeune would confer as required with the USFWS in assessing the impacts and determining appropriate mitigation measures for any Federal Candidate species (See section 4.6 for Permit Requirements and Agency Approvals). In the SDZ, outside the actual range, target and support facility areas, the impacts would be minimal as only non-explosive ordnance would be used on the range. Additionally, regarding several of the rare plant species identified within the GSRA, the NHP staff notes that the Marine Corps' development and management of the GSRA will entail clearing, mowing and controlled burns of roadways, powerline corridors and firing ranges. If properly done, these practices would be beneficial to several of the listed rare species. In fact, in contrast to the previous managed monoculture associated with timber operations, the early- to mid-successional habitat created by the construction and operation of the range would increase overall biodiversity within the GSRA. The wildlife impacts of the Proposed Action appear to be limited to displacement of some common species from the maneuver area as a result of clearing and the presence of personnel and machines. The site has been heavily affected by previous timber production activities, and current animal populations are considered only remnants of the native fauna. It can be expected that as the monoculture is gradually replaced, the successional habitat will attract an increased variety of fauna. Projectiles from the proposed MPTR (non-explosive) would have a negligible effect upon wildlife and habitat in the SDZ. 2-13 Respecting wetlands impacts, the proposed MPTR maneuver and support facility area are both located in an area of relatively high ground. A wetlands delineation was conducted of a rectangle containing 1150 acres in the northeast quadrant of the GSRA (Fall 1993- Spring 1994) to facilitate optimum design and siting of the 740 acre MPTR in an effort to maximize wetlands avoidance. Of the 1150 acres surveyed, approximately 39 percent (443 acres) were jurisdictional wetlands. Several range design layouts were analyzed in arriving at the chosen alternative. The Corps of Engineers (Huntsville) has estimated the impacts at approximately 25 acres, and the Marine Corps has agreed to mitigate the actual wetlands impacts of the MPTR (upon ground-truthing of the chosen design) by restoring previously drained wetlands at a minimum of a 2:1 mitigation ratio. The SDZ fan for the MPTR is largely hardwood swamp forests and pocosin communities which are considered to be valuable wetland resources. This is not considered to be a significant problem, however, due to the fact that only non-explosive ordnance will be used on the proposed MPTR, and the impact of these rounds in the SDZ would be widely dispersed and cause minimal physical damage. Cultural Resources No cultural resources have been discovered which would be affected by the construction and operation of the proposed MPTR. A limited Phase I Archeological and Cultural Resource Study of GSRA (historic document/map research) failed to identify any archaeological sites in the vicinity of the proposed MPTR. A Phase IB Archeological Field Survey of the proposed MPTR site was conducted (Louis Berger, Apr., 1993). No sites were discovered within the proposed maneuver or support facility area, but six archaeological sites (considered potentially eligible for listing in the National Register of Historic Places by the North Carolina Department of Cultural Resources, NCDCR Letter of 12 August 1993), and one isolated find were identified in an area to the north of the proposed MPTR site. The presence of these sites, in conjunction with wetlands considerations, were factors utilized in determining the most advantageous site for the proposed range. It should be noted, however, that soils in the extreme western area of the SDZ fan indicate a medium to high potential for cultural resources, and a survey in this area is scheduled for July 1994. Because of the extreme distance to the proposed MPTR maneuver area in the northeast quadrant of the GSRA, no impacts to cultural resources in the western SDZ are anticipated, although any discoveries would be coordinated with the SHPO for regional analysis. Associated with the construction of the proposed MPTR would be a borrow pit in the Verona Loop area of MCB Camp Lejeune. An archaeological field survey was also conducted at this proposed 55 acre site with no sites discovered (Ogden, Jul., 1993, Appendix D). Ground Traffic There will be impacts on local traffic caused by construction vehicles if the MPTR should be constructed, and during range operation by the transport of tanks and personnel on public roadways from MCB Camp Lejeune to the GSRA. During the construction phase, construction fill and gravel/crushed stone for road construction, and other construction material deliveries, would create the largest traffic impact associated with the proposed MPTR. If the MPTR becomes operational, the impact on public roads is not anticipated to be significant, as only two tanks at a time will be transported by truck to the range. In the longer term, the use of public roads will significantly decrease if the proposed 2-14 s military roads, tank trails and the U.S. Highway 17 underpasses are built as planned to provide direct access from MCB Camp Lejeune to the GSRA. Any negative impacts currently associated with transporting personnel and equipment to off-base training locations (e.g. Fort Knox, KY) would be eliminated by the construction of the MPTR. Airspace Requirements A draft agreement between the Federal Aviation Administration (FAA) and the Marine Corps addressing restricted airspace over the GSRA, including scheduling, use, and mitigation measures, has been negotiated and is undergoing the review and signature process. This agreement would establish permanent restricted airspace above the GSRA to 6,999 feet above mean sea level (MSL) 0600 - 1800 (Local), Monday through Friday (other times by Notice to Airmen-NOTAM). Above 6,999 feet MSL, the airspace could be scheduled for military use up to 17,999 MSL, but only with 30 days prior notice to the FAA so that a Notice to Airmen (NOTAM) could be issued. Mitigation measures to minimize the impacts on civil aviation are contained in the agreement, including various options to interrupt training and allow civil aviation to pass through either GSRA restricted airspace, or MCB Camp Lejeune restricted airspace to the east. The airspace over the GSRA would be divided into two sections (north and south) to provide greater flexibility and allow for less impact on the use of the V-139 Airway (see Section 4.2.5, Air Traffic, for a detailed discussion of mitigation measures). Two private airports (Sky Manor and Holly Ridge) which might otherwise have been affected by a three mile buffer zone requirement have been considered in the USMC/FAA draft agreement, and the boundaries of the restricted airspace adjusted so that public use airspace approaches and departures below 1,500 feet MSL would not be restricted at any time. Noise Operation of a MPTR in the GSRA as proposed would create additional noise impacts not now associated with MCB Camp Lejeune operations. Using the EPA approved Day-Night Level (DNL) model noise evaluator, a noise analysis was conducted by the US Army Environmental Hygiene Agency, Bio-Acoustics Division, Aberdeen Proving Ground, Md. based on the proposed weaponry (120 mm. main tank gun being the largest weapon analyzed), and the proposed usage of a MPTR located in the northeast quadrant of the GSRA. This analysis reflects that unacceptable noise impacts would not be experienced outside the GSRA. (Training and Operations Div., MCB Camp Lejeune). Public Access Control and Safety Inadvertent public access (or trespass) into the MPTR, including the maneuver area, the support facilities area, and the SDZ presents public safety concerns. Military regulations require warning signage to be posted at ingress points and around the perimeter of sensitive or dangerous areas, and barricades to be erected where lasers are used. Currently, "No Trespassing" signs are posted around the perimeter of the GSRA, and further protective measures may be undertaken if the MPTR is constructed. Based on experience at MCB Camp Lejeune, effects on public safety from operation of the proposed MPTR would be minimal. 2-15 2.2.4 Environmental Impacts of Alternative 2 (No Action) The "No Action" alternative amounts to a continuation of the status quo. It involves continued heavy use of ranges on MCB Camp Lejeune, and of off-base training facilities, with the attendant impacts associated with the additional training pressures at those locations. This alternative involves no construction or training-related environmental impacts within the GSRA. Impacts on water quality within the GSRA would be minimal and would be associated with maintenance and natural resource management responsibilities. The potential for wildfire in the GSRA would be significantly less than that of a training scenario. Under both alternatives, because the GSRA tract now belongs to the Marine Corps, it could be expected that new positive effects of the MCB Camp Lejeune natural resource management program, particularly regarding timber management, exemplary natural area maintenance and wildlife/vegetation (including endangered or threatened species) programs, would result. Presently, these concerns are adequately handled at the ranges in use, and no additional impact is foreseen from continuation of the status quo. No impact is expected upon cultural resources, either within the GSRA or at current training locations. Regarding airspace restrictions and noise impacts, the "No Action" alternative would not alter the present situation, either at MCB Camp Lejeune or at off-base training locations. Continued use of off-base ranges would result in marginal additional impacts associated with the higher levels of usage. Minor traffic impacts are associated with the transportation of vehicles and personnel to off-base facilities, and although safety concerns are associated with existing range use, no additional impact is foreseen from continuation of the status quo. 2.3 Comparison of Alternatives From the operational criteria standpoint, the Proposed Action alternative is the strongly preferred choice; from an environmental criteria standpoint, the No Action alternative is somewhat preferable. The Proposed Action may have minor impacts on water quality during construction and operation of the proposed MPTR, but these impacts are largely subject to mitigation. No Action would avoid any water quality impacts associated with development or use of the proposed MPTR. Activation of the proposed range would increase wildfire potential and therefore, from the perspective of fire concerns, the No Action alternative is environmentally preferable. No Action would result in a more benign resource management program for the GSRA as a whole, whereas the development associated with the Proposed Action would require a positive program to locate, manage and protect significant natural assets. For that reason, the Proposed Action is judged to be marginally preferred with respect to that issue. Regarding wetlands, wildlife and vegetation (including endangered/threatened species), or. -valance, the No Action alternative is considered the environmentally preferred alternative (although it is impossible at this time to assess the potential benefit for several of the rare plant species which may occur from positive resource management -ractices by the Marine Corps). Although subject to mitigation, minor erosion impacts to some wetlands would be difficult to avoid, particularly during the 2-16 t construction phase of the proposed MPTR. No Action would preclude any impacts to wetlands within the GSRA, and would also avoid any impacts to the present wildlife or vegetation. Since no cultural resources have been discovered which would be impacted by the proposed MPTR, either in the GSRA or in the construction fill borrow pit area, the l a ternatives are judged environmentally equal. With respect to airspace requirements and noise impacts, the No Action alternative, or the status quo, is environmentally preferable to establishing additional restrictions or noi se sources. Despite some initial negative effects, ground traffic impacts from the two alternatives are viewed as being approximately equal. In the short term (during construction) and in the mid-term (until direct access to MCB Camp Lejeune witho t f u use o public roads is constructed) the Proposed Action would have some minor negative impacts on traffic. The longer term elimination of the need to transport equipment and Marines to off-base training locations is a positive benefit of the Proposed Action. The No Action and the Proposed Action alternatives are judged to be equal regarding impacts on public access control and safety , as the military ownership of GSRA, as with the rest of MCB Camp Lejeune, precludes open access to the area regardless of use. 2 4 S l ti . e ec on of Preferred Alternative Although the No Action alternative is marginally preferable in terms of environmental impacts, it is clearly deficient from an operational perspective. The Proposed Action is a significant step forward in assuring that the Marine Corps' trainin re i g qu rements are satisfied in an efficient and cost effective manner. On balance, the Proposed Action's contribution to military readiness outweighs the manageable impacts associated with its construction and operation. Furthermore, the environmental impacts identified are minor and are largely subject to mitigation. s t s 2-17 AFFECTED ENVIRO 3.0 NMENT This section discusses the existing natural and man-made environment in and around the site of the Proposed Action. The following descriptions are based in part on information contained in the documents listed in Section 5, Data Sources, and on information gained from field surveys conducted in the GSRA together with interviews and correspondence with MCB Camp Lejeune personnel. 3.1 Natural Environment 3.1.1 Climate The North Carolina coastal plain characteristically maintains a relatively mild climate. The coldest month is January, with an average temperature of 47.8 degrees Fahrenheit. The hottest month is July, with a mean temperature of 82.4 degrees Fahrenheit. The relative humidity in this region averages 70 to 75 percent. While seasonal variations are generally marginal, higher humidity tends to occur in the winter, with lower humidity found during the spring. The average annual precipitation is approximately 51 inches. Rainfall is well distributed throughout the year with a distinct seasonal variation during the summer months and September. Total rainfall ranges from approximately five to seven inches during this period. The average monthly rainfall is 3.25 inches during the fall and winter. Snowfall is not common in the area, with less than an inch of snow occurring in the period from December through March . During fall and winter, prevailing winds are from the north and northeast. Winds predominate from the south or southwest in spring and summer. The annual average wind speed is nine miles per hour, with speeds highest at midday. Winds above twenty miles per hour are rare. The highest wind speed recorded in a typical year is approximately 40 miles per hour. Winds gusting at speeds greater than 40 miles per hour are very unusual and typically are associated with heavy thunderstorms or tropical disturbances. l Every few years, the North Carolina coastal region is subjected to the intense rainfal and tidal surges, high winds and seas accompanying hurricanes. The hurricane season begins in June and often extends into November. The east coast of North Carolina is vulnerable to hurricanes, and has been affected by at least 30 such storms in the last eighty years. These storms are accompanied by heavy rain and strong winds which may cause unusually high tides and seas. Approximately three to five "Northeasters", generally the most powerful of storms (other than hurricanes), occur each year. Each of these storms lasts from three to five days. 3.1.2 Topography The coastal topography of the region is composed of broad, relatively flat stream areas, with relief provided by low ridges and dunes. Rivers have cut deeply into sediments, and riverbanks are quite steep. Rivers draining the area south of the Neuse River include the White Oak, New River, the Northeast Cape Fear, and Cape Fear. Tidal flats, and freshwater swamps, such as bays and pocosins marshlands are extensive. Pocosins , , , 3-1 which are freshwater wetlands commonly described as evergreen shrub bogs, occur over flat, clay-based soils on divides between rivers and sounds of the southeastern coastal plain. The topography throughout the GSRA is flat or gently rolling, with elevations that vary only from 38 to 67 feet above sea level. The eastern portion of the GSRA contains the most varied topography, while the western and central portions are primarily broad, flat, poorly drained instream areas. Narrow ridges, hardwood drainage ways, pond pine pocosins, and mineral soil flats are the predominant land forms in the GSRA. Both pine plantations and mature natural pine stands characterize the upland sites, and it is such an area in which the proposed MPTR would be constructed. Elsewhere, creeks and tributaries drain inaccessible lowland hardwood areas and pocosin. The GSRA drainage basin consists of Sandy Run Swamp Creek and two runs of Shelter Swamp Creek and Juniper Swamp Creek. The creeks flow into Holly Shelter Creek, which subsequently flows into the Northeast Cape Fear River. 3.1.3 Geology The geology of coastal North Carolina consists of a Cambrian granite basement, Tertiary and Upper Cretaceous sediments, and a veneer of both Pleistocene and recent sand, gravel and clay. A series of terraces and scarps provide surface topography and evidence of changes in the sea level during Pleistocene and recent times. Three stratigraphic units are associated with the Onslow County substrata, which occur beneath a thin layer of surficial sands and clays: the Yorktown formation, and beneath it, the Castle Hayne and Pee Dee formations. These formations are the area's primary , aquifers: • The Yorktown formation is a fossilized marine sandstone and shell marl approximately 75 feet thick occurring at depths of 0 to 75 feet below mean sea level (MSL). This formation has great erosion potential where outcrops occur in drainage areas. • The Castle Hayne formation is composed of white or gray shell material and white sand. The formation thickness rarely exceeds 100 feet, commencing approximately 75 to 100 feet below MSL. • The Pee Dee formation is the oldest stratigraphic unit penetrated for well water in Onslow County. It is composed of layers of sandy clay alternating with layers of dark-green to glauconitic sand. The formation is approximately 80 feet thick, occurring 175 to 200 feet below MSL. 3.1.4 Soils GSRA soils are classified in soil series by the U.S. Department of Agriculture, Soil Conservation Service (SCS)(DEIS, 1989, Vol. I, Sec. III). This classification is based upon similarities in color, texture, structure, and drainage conditions. In the GSRA, there are nineteen soil types, ranging from muck to sandy loam and fine sand, and most are represented in the northern GSRA. A majority of the soil types are characterized as a fine sandy loam, with the primary soil types within the proposed MPTR maneuver and facility support areas being Leon fine sand, Manville fine sand, and to a lesser extent, 3-2 t Stallings loamy fine sand. Additionally, these soils are classified by the SCS as either hydric (wet) or nonhydric (dry). A brief description of the primary soil types follows. Hydric soils comprise nearly 77 percent of the GSRA, as a whole, and approximately 70 percent of the proposed MPTR maneuver area (740 acres)/support facility area (115 acres). These soil types include Croatan muck, Muckalee loam, Torhunta fine sandy loam, Woodington loamy fine sand, Murville fine sand, Leon fine sand, Rains fine sandy loam, and Pantego mucky loam. • The Croatan soil series consists of a very poorly drained, highly decomposed and extremely acid organic soil. The high water table of Croatan soil (0-1 foot below ground surface) imposes a very severe limitation to development and vehicular traffic. • Muckalee soil series consists of a poorly drained floodplain soil which is subject to frequent overflow. The high water table of Muckalee soil (0.5-1.5 feet below ground surface) imposes a severe limitation to development and vehicular traffic. • The Torhunta and Woodington soil series consist of nearly level, poorly drained soils on stream terraces and divides. The high water tables of Torhunta (0.5-1.5 feet below ground surface), and Woodington soils (0.5- 1.0 feet below ground surface) impose a severe limitation to development and vehicular traffic. • The Murville and Leon soil series consist of poorly drained sandy soils in flatwoods, pine-hardwood forest, cleared and reforested areas. The high water table for Murville and Leon (0-1 feet below ground surface) imposes a moderate to severe limitation to development and vehicular traffic. Non-hydric soils series comprise about 23 percent of the GSRA, as a whole, and approximately 30 percent of the proposed MPTR maneuver/support facility area. The major non-hydric soils are Foreston and Stallings loamy fine sand. • The Foreston and Stallings soils series consist of moderately to poorly drained sandy soils on flatwoods and broad smooth stream divides. The water tables for Foreston soil (2.5- 3.5 feet below ground surface) and Stallings soil (1.0-2.5 feet below ground surface) impose a slight to moderate limitation to development and vehicular traffic. 3.1.5 Hydrology The Great Sandy Run Pocosin, along with its associated creeks and artificial drainage ways, is the dominant hydrologic feature in the GSRA. Five major drainage outfalls are located uniformly throughout the GSRA including Sandy Run Swamp Creek, Juniper Swamp Creek, two runs of Shelter Swamp Creek, Haws Run, and Hick's Run. Sandy Run Swamp Creek, Juniper Swamp Creek, and Shelter Swamp Creek provide outlets to secondary and primary watercourses that feed the Northeast Cape Fear River 32 miles to the west. The creeks are small with their headwaters generally located in the pocosins. Haws Run and Hicks Run discharge in a northeasterly direction to the Southwest Creek, which discharges into the New River (DEIS, 1989, Vol. I, Sec. 111). Precipitation is the primary input source of water in the GSRA. The three water outputs are evapotranspiration, surface runoff, and groundwater discharge. Evapotranspiration 3-3 and surface runoff are the primary routes of water departure from the pocosin systems, and loss of water by discharge is the least significant. Surface water in the creeks and ponds of the region is derived from two sources: surface runoff and groundwater discharge. Surface runoff in the area is rather slow because of the flat terrain. Additionally, the pocosins act like giant sponges, soaking up and retaining water. Hydric soils, such as the Croatan soil, tend to hold water for long periods of time. Thus, streams draining pocosins usually do not flood, and will retain good flow even during periods of drought. Groundwater discharge to the various drainage outfalls is slow and virtually continuous. In the GSRA, 60 to 79 percent of water output is through evapotranspiration when precipitation is heaviest during the summer and fall. During the summer, the water table may be significantly lowered, giving the wetlands extensive storm water storage capacity, and increasing the possibility of peat fires. Although average precipitation declines during the winter and spring, the effects of a low rate of evapotranspiration may result in the water table being at or near the surface. Increased precipitation during this period may result in increased runoff. During the last several decades, timber land owners have attempted to establish pine plantations within GSRA. During the past ten to fifteen years, extensive primary and secondary drainage ditches were constructed by International Paper Company (IPC) throughout the GSRA to allow equipment access to previously inaccessible areas and to remove surface runoff. Drainage ditches were installed to lower the water table to a limited extent, but the main purpose of the ditching was to remove surface runoff to assure the establishment and growth of the loblolly pine plantations. Approximately four percent of the GSRA's pocosin community has been totally disturbed; that is, drained and ditched, natural vegetation removed, and soils prepared for intensive forest management. The majority of the GSRA, approximately 56 percent, is currently in transition, with the pocosin areas either partially altered (drained and ditched only), or disturbed to the point where native vegetation and ecosystem processes are changing. Within the GSRA interior, water drainage has been greatly accelerated by the extensive ditching network placed there by the timber industry. The direction of water flow represents the existing flow pattern of surface water drainage from small ditches into large channels, and eventually into the natural drainage arteries. Each of the three primary natural drainage ways have been channeled to some extent to enhance water flow. The largest network of ditches drains the north central pocosin from the north into westerly flowing man-made channels which empty into Sandy Run Swamp Creek in the northwest quadrant. A portion of the north central area also is drained to the south by a separate series of ditches and westerly flowing channels, eventually draining into the northern fork of Shelter Swamp Creek. The proposed MPTR maneuver area has not been ditched extensively, although there are ditches paralleling the dirt roads that traverse the site. 3-4 1 3.1.6 Water Quality Water within the Pee Dee formation, the deepest of the three area aquifers, is low in minerals, and such constituents as silica, iron and sulfate are rarely present in objectionable quantities. Water in the Castle Hayne and Yorktown formations is closely related to the solubility of the calcareous deposits. The water is medium hard, and in many places, iron is present in objectionable quantities. Hydrogen sulfide produces a slight odor in wells throughout most of the area. Water in the surficial sands is soft and is low in total mineral content. The chief objection to its use is corrosiveness due to the presence of oxygen and carbon dioxide. Septic tank wastewater treatment facilities are the only known source of surficial aquifer pollution in the immediate proximity of the GSRA. The present efficiency of treatment provided by septic tanks in the Greater Jacksonville Area and throughout the county is very low, but due to the low density rural development in the immediate vicinity, domestic groundwater pollution does not appear to be a problem. Another potential source of groundwater pollution at the proposed MPTR site, and the primary threat to the coastal region's future water supply, is salt water intrusion. As water load demands increase, the encroachment of salt water via seepage through the bedrock can occur. Limestone aquifers can become contaminated by vertical encroachment of water from the underlying salt water layer. The creeks within the GSRA are rated Class C, which means fit for aquatic life, but not bathing or as a water supply. The creeks of the GSRA are also designated as "swamp waters", which are defined as waters which have low velocities and other specific natural characteristics. alit 3 1 7 Air Q . . u y The proposed MPTR is located in an area where air quality is excellent. Ambient concentrations of pollutants are well below the standards set forth by the Clean Air Act for particulate matter, ozone, sulfur dioxide, nitrogen oxides, carbon monoxide, and lead. The coastal location and flat terrain, which are subject to constant sea breezes, ensure that inversions and other meteorological events do not contribute negative impacts to air quality. Additionally, due to the rural character of the Onslow County area, air quality degradation is not expected to be an issue in the foreseeable future. There are no significant air quality issues associated with the proposed MPTR, or the GSRA generally, with the exception of wild fires, which are discussed in another section. 3.1.8 Vegetation (Including Endangered and Threatened Species) The various biotic communities in the GSRA generally, and more specifically in the area proposed for the siting of the MPTR maneuver area and support facilities, include reforested pine plantation, hardwood swamp forests, hardwood bottomland/floodplain, and tall pocosin (DEIS, Vol. IV, Figure 32A). The vast majority of the proposed 740 acre maneuver area and 115 acre support facility area is situated in reforested upland pine plantation community. The previously altered pine plantation does, however, merge with sections of hardwood swamp forests, hardwood bottom land/floodplain, and tall pocosin around the perimeter of the proposed MPTR maneuver area. The deciduous 3-5 hardwood swamps are located primarily on the edges of the northern and western extremes of the MPTR. They occur in depressions within or adjacent to pocosins. A small section of hardwood/floodplain community, made up of fertile, moist bottomland with creeks, tributaries and floodplains is located to the north and east of the proposed maneuver area. These communities are typically rich and diverse in animal life . A section of tall pocosin, which is distinguished from the short pocosin by pond pine (Pinus serotina) and titi-fetterbush (Cyrilla racemif/ora)-(Lyonia lucida), is situated along the southern margin of the proposed MPTR maneuver area. Radiating westward from the start line of the proposed maneuver tank trails into the mid-section of the GSRA is the proposed SDZ fan, which covers approximately 5,900 acres. This portion of the GSRA is dominated by short and tall pocosin communities. The densely vegetated pocosins are not generally inhabited by a significant variety of animal species, however, they may serve as a refuge and a feeding area for animals from surrounding biotic communities. The original vegetation in the project site, primarily the shrub/scrub pocosin wetland, has been substantially altered by former timber management techniques. In the vicinity of the proposed MPTR, forestry management practices ranged from clearing native vegetation and planting large stands of loblolly pine, to channelizing stream beds and establishing drainage ditches. The site chosen for the proposed MPTR is a substantially cleared area of non-merchantable pine stands that were highly altered vegetative systems low in plant biomass and species diversity. Vegetation associated with the understory of these loblolly pine plantations include, broomsedge (Andropogon virginicus), gallberry (Ilex sp.), blueberry (Vaccinium sp.), sweet pepperbush (Clethra alnifolia), and wax myrtle (Myrica cerifera). Various herbaceous species, such as pitcher plants (Sarracenia sp.), ferns, and mosses are also common in pine plantation understory. Hardwood swamp forests are located in isolated stands, primarily around the northern and western boundaries of the proposed MPTR maneuver area and generally in the eastern segment of the SDZ fan. Dominant vegetation of the hardwood swamp forests is swamp black gum (Nyssa sylvatica), sweet bay (Magnolia virginiana), and red maple (Acer rubrum). Bald cypress (Taxodium distichum) occurs in isolated stands on the wettest sites with the longest hydroperiod, whereas the swamp black gum is more numerous in areas of shorter hydroperiods. The understory is composed of fetterbush (Lyonia lucida), gallberry species, titi (Cyrilla racemiflora), switchcane (Arundinaria gigantea), greenbrier (Smilax sp.), ferns and mosses. A small finger (approximately 5 acres) of a larger hardwood bottomland/floodplain abuts the northeastern sector of the proposed maneuver area. Plant species characteristic of these areas are dictated by specific hydric regimes as in the hardwood swamp communities. Swamp black gum and sweet gum (Liquidambar styraciflua) are dominant vegetation. Water oak (Quercus nigra), sweetbay, red maple, loblolly bay (Gordonia lasianthus), American holly (Ilex opaca), white cedar (Chamaecyparis thyoides), and laurel oak (Quercus /aurifolia) are also associated with this community. Vegetation in the shrub and ground layers include wax myrtle, large leaf bayberry (Myrica heterophyl/a), cinnamon fern (Osmunda cinnamomea), Virginia sweetspire (Itea virginica), switchcane, dahoon holly (Ilex cassine), myrtle dahoon (Ilex myrtifolia), and rhododendron (Rhododendron viscosum). 3-6 A tall pocosin community, with its characteristic pond pine/titi-fetterbush community, shallow peats and moderate hydroperiods, is located near the southwestern boundary of the proposed MPTR maneuver area, with a small section possibly intruding into the proposed maneuver area. The majority of the SDZ fan associated with the proposed MPTR is comprised of tall pocosin surrounding short pocosin communities. The tall pocosin usually occurs on the perimeter of short pocosin and contains similar vegetation, but the pond pines, which are intermixed with longleaf and loblolly pines, appear more mature and compose greater than 20% of the canopy. Titi and fetterbush dominate the shrub layer, averaging heights greater than two meters. Mosses, ferns and switchcane are included in the herbaceous vegetation of the pocosin. Associated with the ground layer are sweet bay, red bay (Persea borbonia) and loblolly bay (Gordonia lasianthus). Bald cypress and Atlantic white cedar scattered throughout the tall pocosin, are remnants of the cypress and cedar forests that were eliminated by past logging activity. Endangered/Threatened Flora Twenty-six plant species recognized as rare at the Federal or State level have been identified within the entire GSRA. Under the Federal program, rare species are given protection either as Endangered or Threatened (and a third designation - "Proposed" - provides a reduced level of protection). Candidate species are those under consideration for Federal listing. Under North Carolina's program, species provided legal protection are ranked as Endangered, Threatened or Special Concern. Categories of "Proposed", "Candidate", "Significantly Rare", or "Watch List" reflect a decreasing priority of unprotected status. Fifteen of the 26 plant species were located in the northern GSRA, with four species having Federal designations (NHP Inventory, Jul., 1993). The Federally designated species include: Federal Endangered - rough-leaved loosestrife (Lysimachia asperulaefolia); Federal Candidate ( All Level 2 - species for which there is some evidence of vulnerability, but for which there are not enough data to support listing as Endangered or Threatened at this time) - savanna cowbane (Oxypolis ternata), Carolina goldenrod (Solidago pulchra), Carolina asphodel (Tofieldia glabra). All four of these Federally designated rare plant species, plus an additional eleven State designated plant species of varying levels of rarity ranging from Endangered down to Significantly Rare are located in the northern GSRA , . The NHP Inventory has calculated that four of the rare plant species listed in Table 1 are present in the GSRA in significant percentages of known global populations. The GSRA contains 39 percent of the known global population of the Carolina goldenrod in 41 located sites. (Between MCB Camp Lejeune and the GSRA, the global population of the Carolina goldenrod percentage is estimated to be 60 percent.) The GSRA contains eight percent of the global populations of Thorne's beaksedge (one site) and venus flytrap (13 sites). Five percent of the global population of the rough-leaved loosestrife (four sites) is identified in the GSRA. Global rank is based on a species' abundance rangewide, and is the best available scientific assessment of a species' rarity throughout its range.

This herbaceous vegetation is a source of food and cover for the variety of birds and mammals that may currently inhabit the general vicinity of the proposed MPTR. Herbivorous and insectivorous species, such as white-tailed deer (Odocoileus virginianus), wild turkey (Meleagris gallopavo), gray squirrel (Sciurius carolinensis) and bobwhite quail (Colinus virginianus), are known to occur in this forest type. The hardwood swamp forest, and the hardwood bottom land/floodplain communities (northern and western periphery of the proposed MPTR) are typically rich in animal life, and usually have the greatest diversity of animal species. Fauna reported and/or frequently observed in these deciduous regions include various waterfowl, wild turkey, mink (Mustela vison), otter (Lutra canadensis), raccoon (Procyon lotor), gray squirrel, beaver (Castor canadensis), bobcat (Lynx rufus) and white-tailed deer. Small mammals found in the hardwood swamp forest and hardwood bottomland/floodplain areas include the hispid cotton rat (Sigmodon hispidus), cotton mouse (Peromyscus gossypinus), and eastern woodrat (Neotoma floridana). Of the four biotic communities that occur in the general vicinity of the proposed MPTR maneuver and support facility areas and associated SDZ, tall and short pocosin are most likely to serve as refuge and feeding habitats for wildlife that may inhabit the other communities. The densely vegetated pocosin communities are not generally inhabited by a large variety of animal species. No species are recognized as being truly endemic of this community, but the native spotted turtle (Clemmys guttata) is characteristically found in creeks associated with pocosins (Wilber, 1981). Tall pocosin, similar to that found throughout the proposed MPTR SDZ, provides feeding and nesting areas for many bird species. Bobwhite quail, mourning dove (Zenaida macroura) and many of the additional 38 species of birds observed in the GSRA can be expected to frequent the pocosin. Mammals captured within the tall and short pocosin include the southern short-tailed shrew (Blarina brevicauda telmalestses), cotton mouse, golden mouse (Ochrotomys nuttalli aureolus), and hispid cotton rat. Other species which are reported locally and are restricted to aquatic areas within pocosins include the river otter, mink, and muskrat (Ondatra zibethicus). White-tailed deer inhabit pocosin, but the population densities are lower than the other biotic communities of the region. The limited amount of browse within the pocosin is considered a contributing factor of this significantly smaller population of deer (DEIS, Vol. 1, Section III, 1989). It is speculated that the pocosin may offer refuge to wildlife that at one time ranged widely, but are now confined to isolated tracts of suitable habitat due to human encroachment and habitat destruction (Wilbur, 1981). Black bear (Ursus americanus), which are associated with pocosins of North Carolina, have been reported by area residents, and an ongoing bear study (tagging/radio collar) has revealed that there are several animals presently inhabiting the GSRA. 3-10 I Endangered/Threatened Fauna The NHP Inventory has reported no sightings or evidence of Federal or State endangered or threatened animal species in the proposed MPTR maneuver or support facilities area or its SDZ. During field work in the Padgett Swamp Road area under the western fringe of the proposed SDZ, NHP staff located two sites with potential for red-cockaded woodpecker (Picoides borealis) habitation, and two sites with potential for Bachman's sparrow (Aimophila aestivalis) habitation, although no birds were discovered. Elsewhere in the GSRA, the following three rare species were identified by the NHP Inventory: Bachman's sparrow, a Federal Candidate (Level 2)/State Special Concern species, Henslow's sparrow (Ammodramus henslowil), a Federal Candidate (Level 2)/State Significantly Rare species, and the eastern woodrat (Neotoma floridana floridana), a State Threatened species, but all were located in the southern sector of the GSRA below Moores Ridge Road, remote from the proposed MPTR. 3.1.10 Wetlands In the Spring of 1994, remote sensing of aerial photography, soil survey, and topography, Geographic Information System (GIS), and Global Positioning System (GPS) technologies, in conjunction with field surveys, were used to delineate wetland boundaries within a rectangular area comprising 1150 acres in the northeast quadrant of the GSRA, and within which the proposed MPTR (encompassing a rectangle of 740 acres) would be sited. Wetland boundaries and cover types were digitized into the GIS for analysis of wetland areas. The digital layers were georectified according to known (surveyed) control points provided by MCB Camp Lejeune to create an accurate map of wetlands within the proposed range area. The results revealed that within the 1150 acre survey area there were 443 acres of jurisdictional wetlands (39 percent). Forest scrub-shrub wetlands accounted for the greatest wetland acreage with 315 acres (27 percent of total-not of wetlands), followed by scrub shrub wetlands with 59 acres (5 percent), forested wetlands with 48 acres (4 percent), and emergent wetlands with 21 acres (2 percent). There were 15 wetland cover types delineated. The greatest area (297 acres) of wetland cover type was pine forest with gallberry or mixed bay shrubs growing on saturated sites. An analysis of this 1150 acre rectangle was conducted and a MPTR range site and design chosen which would minimize wetland impacts (Figure 3-2). The Corps of Engineers estimates that there would be approximately 25 acres of wetland impacts associated with the preferred MPTR range design (including access road to the range) which involves a rectangle covering some 740 acres total. With regard to the GSRA as a whole, the wetland areas have been generally categorized as Palustrine Forested Wetland (PFO) and Palustrine Scrub or Shrub Wetland (PSS). PSS wetlands represent the pocosin communities which comprise large portions of the wetland mosaic within the SDZ fan (approximately 4,000 acres total), and are the dominant type of wetland within the GSRA. 1 3.1.11 Exemplary Natural Areas As noted above (section 2.2.3), the NHP Inventory found three natural areas within the GSRA of sufficient size and quality to recommend special attention and/or protection be 3-11 w a z a C) z zz <o ?a ww Nz a w M a. w °G o °C a o ?

These three areas include the Greater Sandy Run Pocosin (two large pocosin basins separated by Moores Ridge Road (10,500 acres total), an area in the vicinity of Padgett Swamp Road in the northwestern sector of the GSRA (125 acres), and an area in the vicinity of South Bay road in the southeastern sector of the GSRA (48 acres)(Figure 2-2). The Padgett Swamp Road area (which contains exemplary pond pine woodland, pine savanna, and wet pine flatwoods) and the South Ba R d , y oa area (which contains exemplary pine savanna and small depression pocosin) support several rare species, including the Federal Endangered rough-leaved loosestrife. The Great Sandy Run Pocosin (two basins) contains extensive areas of pond pine woodland, much of which has been impacted by a network of drainage ditches. Nonetheless, the two large pocosin basins belong to a rare habitat type essentially restricted to eastern North Carolina . 3.2 Man-Made Environment 3.2.1 Land Use Onslow County updated its land use plan in 1991 (Onslow County, 1991) and in the process recognized the acquisition of the GSRA by the Marine Corps. The Plan classifies Greater Sandy Run Pocosin as an environmentally significant area within the "Conservation" classification and notes that "The purpose of this classification is to provide for effective long-term management and protection of significant, limited, or irreplaceable areas." The pocosin, hardwood swamp forests and bottomlands biotic communities fall within this category. Conservation lands can be developed and managed within specified guidelines, and are therefore not set aside for preservation. The Plan notes that appropriate land uses for the Great Sandy Run Pocosin include Expansion of Camp Lejeune Military Reservation. The GSRA falls into Onslow County's "Developed/Military Reservation" land use classification. This classification specifically recognizes that MCB Camp Lejeune functions as a self-sufficient government entity and notes that "those land uses customarily associated with the operation of a military base are considered appropriate." A caveat is contained in the Plan, however, that "new and/or expanded land uses and activities on the Reservation may be inappropriate, and/or inconsistent with County policies, programs and the best interest of the County." While Onslow County desires to review plans for new or expanded land uses, the Plan recognizes that ordinary operation of the Reservation will generate certain negative or objectionable factors outside the Base boundaries (i.e. traffic, both private vehicles and convoys, and noise from training). 3.2.2 Demography, Income, and Taxes In 1990 the total population of Onslow County was 149,838, up 32.9 percent from 112,784 in 1980. Approximately two-thirds of the county is "undevelopable" land, which consists of 24 percent commercial forests, 22 percent military bases, 8 percent water and marsh, and 11 percent state forest. With two thirds of the land unavailable for private development, population growth and industrial development is limited to specific areas of the county. The 41,100 acre GSRA is located within the Stump Sound township of Onslow County, and makes up approximately 40 percent of the land area of the Township. In 1990, the 3-13 Township had a population of 10,148 (including a portion of Camp Lejeune), representing an increase of 35 percent since 1980. One of the localities in the Township experiencing rapid growth is the Verona area, just to the north of the GSRA and the proposed MPTR site in the northeast quadrant of the tract. Onslow County has a relatively stable economy due to the steady source of military and civilian employment provided by MCB Camp Lejeune. MCB Camp Lejeune is the largest employer in Onslow County, followed by retail trade, other government (excluding Camp Lejeune), services, and manufacturing. The average per capita income in Onslow county more than doubled in the ten years between 1975-1985. This trend is expected to continue as the shift from a rural to a more urban lifestyle continues. 3.2.3 Utilities/Infrastructure Electricity There is presently no electrical service to the proposed MPTR site. There is, however, a regional overhead 12.47 KV transmission line which passes north - south through the eastern portion of the proposed site. A portion of this line is scheduled to be moved eastward toward U.S. Highway 17 in conjunction with the proposed construction of the MPTR, and a tie-in to provide power to the site would then be affected. Water There is presently no public water supply in the immediate vicinity of the proposed MPTR site, however, a county water line runs along U.S. Highway 17 immediately east of the GSRA boundary. Current plans call for the drilling of a well in the vicinity of the proposed MPTR to provide water to the range users, however the option exists that a tie- in to the local commercial water source could be made. Wastewater There is no wastewater collection or treatment facility presently serving the proposed MPTR site. If soils prove suitable, a septic field is planned to support the proposed MPTR. The draft Master Development Plan includes an option to tie into the MCB Camp Lejeune sewer system if soil conditions should preclude the construction of a septic system. Telephone Although there is presently no telephone service at the proposed MPTR site, telephone would be provided by extending the eight strand fiber-optic cable which runs from New River to the Verona Loop area of MCB Camp Lejeune. It would be extended across U.S. Highway 17 at Moores Ridge Road to the range headquarters building and a buried telephone cable would be installed to connect the proposed MPTR with the range headquarters control box. 3-14 3.2.4 Traffic and Transportation Ground Traffic There are approximately 5.3 miles of dirt roads within the GSRA in the immediate vicinity of the proposed MPTR site. Reys Road provides access to U.S. Highway 17 and to the Verona Loop Road on MCB Camp Lejeune. The dirt roads were formerly used to support International Paper Company's commercial forestry operations in that area. Access to the GSRA is now restricted to official vehicles, and traffic into and on the reservation is very light. Air Traffic The proposed MPTR site is within the MCAS New River control zone and under the southern entry flight path for aircraft heading to Marine Corps Air Station (MCAS) New River, approximately four miles to the northeast. There are approximately 120,000 flight operations at MCAS New River annually. The proposed MPTR site is also under V- 139, a four mile wide, low altitude (under 18,000 feet) Federal airway between New Hanover International Airport at Wilmington, NC and the Craven County Regional Airport at New Bern, NC. MCB Camp Lejeune has proposed a GSRA joinvintermittent use, stratified restricted airspace area affecting approximately 55 square miles above the entire GSRA (Figure 3-3). This proposal for restricted airspace to accommodate military training operations within the GSRA is currently being finalized. 3.2.5 Noise No ambient noise level data is available in and around the proposed MPTR, however, several noise sources predominate in the area. Low flying aircraft approaching and departing MCAS New River fly generally over the northern GSRA. Helicopter training flights which utilize the Camp Davis Field complex in the southern GSRA traverse along the eastern boundary of the GSRA, leaving and returning to MCAS New River. There are approximately 75 helicopter flights per day (Monday - Friday) between MCAS New River and Camp Davis Field at an altitude of between 500 and 1,300 feet. Additionally, when artillery training is conducted on MCB Camp Lejeune, muzzle blasts and explosions in the G-10 ordnance impact area on MCB Camp Lejeune are audible in the northeast quadrant of the GSRA. r 6 Cultural Resources 2 3 . . No archaeological or historic resources have been identified in the proposed MPTR maneuver area and support facilities site, or in the potential construction fill borrow pit site in the Verona Loop area of MCB Camp Lejeune. Field surveys have been conducted in these areas. The Acquisition EIS (DEIS Vol. I, III-34) predicted that the most probable locations for regionally significant archeological sites were along the northern and eastern margins of the pocosin, based on the high to medium archaeological potential of the soils and elevations in that area (Figure 3-4). Appropriately, the Phase IB Cultural Resource Investigation (Louis Berger, Apr., 1993) did identify six prehistoric sites to the north of the proposed MPTR maneuver area, generally along the Hicks Run drainage near the northeast boundary of the GSRA. These sites have been recommended for additional study. 3-15 cz- Craven Co. Regional Airport New Bern , N I cZ ". M?AS ' Cherry Point Ellis A-530 GSRA oR -5306C ?.; .

"No Trespassing" signs are posted at 200 foot intervals around the perimeter of the GSRA, and road gates (fourteen) for key entry points into the GSRA are in the process of being procured and installed. 3.2.8 Contamination During research for the purchase of the GSRA, a survey was conducted to evaluate the potential for environmental contamination on the tract (Weston 1992). The vast majority of the 41,100 acre tract was determined to have a low potential for environmental contamination, although a few sites around the periphery of the GSRA were identified as requiring remediation. None of those sites, however, were associated with or in the vicinity of the proposed MPTR or its SDZ. 3-18 4.0 ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES 4.1 Natural Environment: Direct Effects and Mitigation Measures Associated with Alternative 1 (Proposed Action) 4.1.1 Climate The Proposed Action would have no impacts on climate. 1 4.1.2 Topography The Proposed Action would have no impacts on topography. 4.1.3 Geology The Proposed Action would have no impacts on geology. 4.1.4 Soils The primary soil types located in the areas slated for MPTR development include Leon fine sand, Murville fine sand, and to a lesser extent, Stallings loamy fine sand. Both the Leon and Murville soil series are typified as poorly drained sandy soils, with the water table typically residing 0 - 1 feet below ground surface. The high water table, coupled with poor drainage, impose moderate to severe development and traffic limitations. The proposed activities which will pose the greatest negative environmental risk involving soils include the proposed construction and use of the two maneuver area tank trails, and the proposed installation of a leach field to handle wastes discharged from the field head facility. The MPTR tank trails would require the complete clearing of two lanes for an approximate surface area of 57.6 acres. Additional cutting of brush would be required to provide lines of sight to targets, however this would be accomplished without soil disturbance through mechanical (i.e. bush hog) or hand clearing methods and a vegetative cover would remain. The removal of vegetation for tank trail construction, and the extensive soil disturbance created by heavy tracked vehicles could, however, contribute to soil erosion in the area. The tank maneuver trails and the access road/tank trail maintenance would require regular additions of fill material to keep the roadway surface above the water table and to keep it from becoming severely rutted. Runoff from these areas could contain high levels of sediment which would add silt to the drainage system and drainage ditches in the area. However, throughout the proposed MPTR maneuver and support facility area, soil erosion impacts would be localized due to the flat terrain and sluggish water flow, and for this reason any mitigation measures should be relatively easy to institute. As an example, during construction phases, temporary ground cover and silt fence would be used to contain erosion. For long term control, vegetative buffer zones, and possibly berms to direct or channel runoff away from sensitive areas, would be included in the range design. Although the proposed maneuver and support areas are not extensively ditched, the introduction of soil sedimentation or siltation in nearby wetlands and those ditches that 4-1 are in the vicinity could present a concern, particularly during the construction phase. As the construction of the proposed range would disturb more than five acres, a Stormwater NPDES permit would be required. Additionally, because Onslow County is one of the coastal counties of North Carolina, additional State permit requirements would be applicable (See section 4.6, Permits). Current plans for sewage disposal anticipate the construction of a leach field. The location of the proposed MPTR buildings, including field service bathrooms, is in an area of hydric soils (Leon and Murville). With the average water table elevations of 0 - 1 feet below surface level, it is recognized that the possibility of subsurface migration of leachate pollutants to surface waters could create problems with water quality degradation and create human health impacts. Coordination with county officials is required once a location for a leach field is chosen, and a local construction permit would be required (See section 4.6, Permits). Should a leach field not be authorized, alternatives include portable toilets or a connection to the MCB Camp Lejeune sewage system, neither of which would create any adverse impacts. Approximately 70,580 cubic yards of fill are expected to be used for the construction of the proposed MPTR. As with the proposed construction of the MPTR, erosion and stormwater runoff issues are equally applicable to the site of the construction fill borrow pit in the Verona Loop area of MCB Camp Lejeune. Standard mitigation measures (silt fence, vegetative buffer zones, collection/settling ponds) would be employed to contain erosion while the borrow operation is active. 4.1.5 Water Quality Unless the option to tie into a commercial water source is chosen, development of the proposed MPTR would entail construction of a drinking water well along with water treatment facilities and distribution lines. While construction of the well itself will not have any significant environmental impacts, the potential for the well to be negatively impacted by other activities should be considered. Any sewage treatment/disposal facilities would be located a safe distance from the drinking water well. Because of the high water table and soil composition in the area of the proposed MPTR, the possibility of the planned sewage leach fields contaminating the drinking water well must be considered (See section 4.6, Permits). 4.1.6 Air Quality The construction and operation of the proposed MPTR is not expected to provide any significant impacts to air quality. Construction would entail a significant amount of earth movement, both within the range and from the off-site borrow pit. This activity would result in fugitive dust emissions as well as emissions from trucks and other earth moping equipment. These emissions would be short term and minor, and subject to mitigation (fugitive dust control). Emissions from activities associated with operation of the proposed MPTR would primarily be particulate matter, with other pollutants emitted to a much smaller extent. Due to the irregularity of emission production (tank movement, gunpowder detonation, vehicle emissions) total emissions for the site are expected to be low. Emissions from fire are the primary concern, and could have a negative impact on air quality if a forest or brush fire should burn for extended periods, and if adverse climatological conditions, 4-2 such as an inversion, are present. Wildfire control would be addressed through MCB Camp Lejeune fire control procedures, and site-specific plans would be developed (See Section 4.1.7 below). 4.1.7 Fire Suppression and Control Non-explosive ordnance is planned for the proposed MPTR operations. This will reduce the potential for forest/brush fires, although other incendiary devices which may be used on the range (including tracer rounds, smoke grenades, booby-trap simulators, and hand-held illumination) would still produce a risk of fire. By far the most serious fire risk in the proposed SDZ fan is the burning of the peat which comprises a large portion of the soil composition of the northern pocosin. The peat can burn for extended periods of time, both above and below ground, causing significant air emissions and possibly posing a human health hazard if smoke is heavy and extensive. Fire management efforts would include increasing periodic controlled burns as part of MCB Camp Lejeune's Natural Resource Management program, increasing fire control personnel from nine to seventeen, and purchasing additional fire control equipment including IM more low pressure tractor and plow units, four portable bridges and four bridge trucks (FEIS, 1991, Section III-30). The long range plans for the GSRA development include three 125 foot observation towers in the northern GSRA and a perimeter road which, if constructed, would provide easier and quicker access to fire locations as well as providing a fire break around the entire GSRA. A revised Fire Control Plan for MCB Camp Lejeune (which includes the GSRA) has been prepared. Mutual assistance agreements with both the U.S. Forest Service and the State of North Carolina have been executed. Additionally, in an emergency situation, the manpower pool for firefighters at MCB Camp Lejeune is significant. 4.1.8 Vegetation (Including Endangered and Threatened Species) Impacts to vegetation would result from construction and use of tank trails and the tank firing lanes within the proposed maneuver area, coupled with the clearing necessary for target construction and line-of-sight openings to sight and fire the weapons. All vegetation would be removed from about 60 acres for the tank trails, and fill and gravel build-up applied. In conjunction with the maneuver lanes, concrete turning pads would be constructed at the defilade positions and at the entrance to the proposed maneuver area. For the installation of targets and line-of-sight range openings, vegetation would be maintained near ground level in an early- to mid-successional state, depending on weapon sighting requirements. Maintaining the vegetation in this state would be accomplished through controlled burns, bushhogging, and/or hand clearing (as required). Converting the proposed MPTR from pine plantation to early- to mid- successional vegetation for construction and operation of the MPTR would increase habitat diversity in the area. Tracked vehicles are not expected to leave the tank trails, thereby minimizing impacts upon vegetation within the proposed MPTR maneuver area. ® For construction of the range support facilities, an area covering about 50 acres will be cleared of most existing pine plantation vegetation to accommodate the buildings and vehicle parking areas. The proposed site for these support facilities, as with the entire proposed MPTR project, lies within an area previously disturbed by commercial timber activities and human presence, and currently includes roads and an electrical 4-3 transmission line. No significant impacts are anticipated if proper erosion control measures are established for the construction and operation of the facility. Overall, damage caused to vegetation from ordnance impacts, such as torn foliage, embedding of projectiles in woody tissue, or localized soil upheaval, would be slight. In the immediate target areas, where the majority of the non-explosive rounds would impact, the vegetation would be affected and the earthen berms designed to receive the rounds would be noticeably impacted. However, the wide dispersal of the misses or ricochets within the large SDZ would result in negligible damage outside the target arrays. Observations of existing ranges at Camp Lejeune indicate that 80 percent of direct fire impacts are contained within the immediate target area. Threatened/Endangered Flora As shown in Section 3.1.8 above, (Table 1, Rare Species Table, and Figure 3-1), there are a number of rare plant species within the northern GSRA which could be affected by the construction and operation of the proposed MPTR. As can be seen on Figure 3-1, the rare plant species are found in two general locations: in the northwestern GSRA under the western end of the proposed SDZ, and in the northeastern GSRA in the vicinity of the proposed MPTR maneuver and support facility area, with special concentrations along the logging loop access road, along Reys Road, and in the powerline corridor. The Padgett Swamp Road area at the western extreme of the SDZ contains the only Federally listed endangered species in the GSRA, the rough-leaved loosestrife. Consultation with the U.S. Fish and Wildlife Service concerning the potential impacts from the operation of the proposed MPTR on the rare plant species located in the northwestern quadrant of the GSRA under the SDZ fan (in the pocosin, and in the vicinity of Padgett Swamp Road) resulted in concurrence with the opinion that the potential for damage in this area from spent projectiles from the proposed MPTR is considered negligible. In a 15 November 1993 letter the USFWS noted: "...construction and operations of the Multipurpose Training Range is not likely to adversely affect the Federally-listed endangered rough-leaved loosestrife." A positive effect would result from controlled access to the area and protection afforded by MCB Camp Lejeune's Natural Resource Management program. The USFWS also noted that while there is a potential of uncontrolled fires resulting from range operations which could negatively affect the loosestrife, MCB Camp Lejeune has "agreed to control wildfire as part of their range management and beneficial habitat management; this includes properly controlling burns, and this commitment will be part of their Natural Resources Management Plan for the GSRA." The rare plant species located in the northeastern GSRA in the vicinity of the proposed maneuver and support facility areas present a different level of concern. Table 2 lists the rare species and their Federal/State status identified in the NHP Inventory. The nine listed plant species (of varying degrees of rarity) are located in areas that would be affected by the construction and/or operation of the proposed MPTR (The number in Column 1 of Table 2 corresponds to the species locations depicted in Figure 3-1). 4-4 Table 2 NORTHEASTERN GSRA RARE PLANT SPECIES Location/Fig. 3-1 Species Name Federal / State Status" 2.

Xyris flabelliformis None/Candidate Savanna Yellow-eyed Grass ' North Carolina regulations establish Endangered, Threatened and Special Concern categories for legal protection; State Candidate status is for species which may require protection, but for which insufficient data are available to support Endangered, Threatened or Special Concern status; and Significantly Rare is a North Carolina Natural Heritage Program designation (= North Carolina Wildlife Resources Commission designation) for species considered to require monitoring, but which have not been designated for protection or candidate status. ' #5 (venus flytrap) has been recommended for Federal designation as Candidate (Level 2, a species for which there is some evidence of vulnerability, but for which there are not enough data to support listing as Threatened or Endangered at this time.) Among the above-listed plant species located in the northeastern GSRA, there are no Federally protected species, but there are two State Endangered species in the area. Two Federal Candidate (possibly three) and three State Candidate species are also in the area. These plants are generally located in relatively open areas such as flatwoods and savanna, powerlines and roadsides, and other clear-cut areas. With regard to the proposed MPTR site, concentrations of these rare plant species are found along the eastern powerline corridor, along Reys Road (a portion of which would be within the proposed maneuver area), and along the logging loop road which would provide access to the proposed MPTR. 4-5 Construction of the proposed MPTR, including the upgrading of the logging loop access road, would undoubtedly impact several identified rare plant communities. Of primary concern is the potential impact on the Federal Candidate species: Carolina goldenrod. This plant is apparently thriving along the Reys Road right of way and in the eastern powerline corridor (NHP Inventory, Jul., 1993, Figure 3-1). Although only a Federal Candidate species at this juncture, a conference with the USFWS would be required (see section 4.6, Permit Requirements and Agency Approvals) to discuss the potential impacts, and possible mitigation measures which could be undertaken to minimize any adverse effects associated with the construction and operation of the proposed MPTR. The NHP Inventory also contains recommendations for habitat management (such as controlled burns/mowing schedules) for each identified rare species. Future GSRA planned development calls for clearing and maintaining open areas for various facilities, roads and ranges (including the proposed MPTR). This, combined with controlled access to large portions of the GSRA and an active Natural Resources Management program, would result in added habitat diversity and a net benefit to several rare species which require an open type of environment. 4.1.9 Wildlife (Including Endangered and Threatened Species) The main impacts upon wildlife in the proposed MPTR would be alteration of habitat associated with range construction and clearing, and the stress associated with increased human presence in the maneuver and support facility areas. However, some species, such as the white-tailed deer, wild turkey, and bobwhite quail prefer more open areas in which to forage. Additionally, for the installation of targets and line-of-site range openings, the shift from a managed timber monoculture to the maintenance of vegetation in an early- to mid-successional state would add to habitat diversity within the GSRA and benefit wildlife in the area. Wildlife within the proposed SDZ is not expected to be impacted by range operations in any significant manner. With the possible exception of fire (which may be controlled burns or accidental wildfires), there is no anticipated alteration of habitat or disruption of the natural areas encompassed by the proposed SDZ. The presence of humans within pine plantations has occurred previously with timber- related practices, hence current animal populations are considered only remnants of the native fauna. Generally speaking, the lack of diversity noted in the current inventory of animal and plant populations, and the deficiency of high-quality natural communities suggests the adverse effects of previous human-induced changes within the GSRA. The increase in human presence, coupled with the periodic intense use of military hardware and weapons within the maneuver area, may drive some permanent inhabitants from the immediate area of the proposed MPTR (especially near target emplacements), while some will simply move to less utilized portions of the GSRA. Some, as has been noted at other ranges, may be expected to adapt and take up residence despite the range operations. Endangered/Threatened Wildlife The NHP Inventory identified no endangered or threatened animal species within the proposed MPTR or SDZ fan. In the vicinity of Padgett Swamp Road (Figure 2-2), the NHP staff did locate several sites that have the potential as red-cockaded woodpecker and Bachman's sparrow habitat, although no birds were found. This area should be monitored. As noted above, a portion of the Padgett Swamp Road area falls within the 4-6 I western extreme of the SDZ fan, but any negative effects in that area from operation of the proposed MPTR, including damage from spent projectiles, are considered negligible. 4.1.10 Wetlands In early 1994, remote sensing of aerial photography, soil survey, and topography, Geographic Information System (GIS), and Global Positioning System (GPS) technologies, in conjunction with field surveys, were used to delineate wetland boundaries within a rectangular area comprising 1150 acres in the northeast quadrant of the GSRA, and within which the proposed MPTR (encompassing a rectangle of 740 acres) would be sited. Wetland boundaries and cover types were digitized into the GIS for analysis of wetland areas. The digital layers were georectified according to known (surveyed) control points provided by MCB Camp Lejeune to create an accurate map of wetlands within the proposed range area. The delineation study revealed that within the 1150 acre survey area there were 443 acres of jurisdictional wetlands (39 percent). Forest scrub-shrub wetlands accounted for the greatest wetland acreage with 315 acres (27 percent of total-not of wetlands), followed by scrub shrub wetlands with 59 acres (5 percent), forested wetlands with 48 acres (4 percent), and emergent wetlands with 21 acres (2 percent). There were 15 wetland cover types delineated. The greatest area (297 acres) of wetland cover type was pine forest with gallberry or mixed bay shrubs growing on saturated sites. An analysis of this 1150 acre rectangle was conducted to determine the best location and design for the 740 acre MPTR. From among several alternatives, a site and design was chosen which would minimize wetland impacts. The Corps of Engineers estimates that there would be approximately 25 acres of wetland impacts associated with the preferred MPTR range design (including access road to the range). A permit from the Corps of Engineers would be required (see section 4.6, Permit Requirements and Agency Approvals), and mitigation would be expected. To address the mitigation requirements associated with the MPTR, and in preparation for further GSRA development, a conceptual wetland mitigation plan has been developed. Altered and disturbed wetlands have been selected throughout the GSRA for wetland restoration. These drained wetlands are historic pond pine pocosin wetlands that have been converted to plantation pine through mechanized silviculture practices, which included implementation of drainage ditches and bedding planes to plant stands of improved loblolly pine. One of the most highly productive soil units for the production of loblolly pine in the GSRA is Woodington loamy fine sand. This soil is a poorly drained soil, and it is found in broad, flat areas adjacent to the two major GSRA Pocosins and the associated streambed pocosins. The Woodington soil series is hydric, and under normal conditions this series supports a seasonally saturated wetland system, having wetland hydrology present throughout the months of December through May of each year. The same soil properties of the Woodington soil series which facilitated easy hydrologic manipulation for plantation pine management will also allow for relatively easy wetland hydrology restoration. A strategic hydrologic monitoring plan has been implemented throughout these drained wetland areas that have been converted to pine plantation. Hydrologic monitoring wells will be strategically placed along carefully planned transects to measure and record the existing water table to verify whether or not wetland hydrology is present on these sites. In those areas in which wetland hydrology is 4-7 found not to be present, a site-specific wetland restoration plan will be developed. Restoration of wetland hydrology would be accomplished by a combination of plugging ditches, which would eliminate the wetland drain, and by cutting the planted pine, which would eliminate the hydrologic pump. It is anticipated that these actions would result in the restoration of wetland hydrology. The monitoring wells shall remain in place to verify the wetland hydrologic restoration success. No further restorative measures should be required to restore wetland functions since hydric soil is present and hydrophytic vegetation already exists in the understory. It is anticipated that the Marine Corps would mitigate for wetland impacts resulting from the construction of the MPTR by restoring previously drained wetlands at a minimum of a 2:1 mitigation ratio. The Corps of Engineers has provided recommendations concerning wetlands mitigation and the development of a wetlands mitigation banking program within the GSRA. For the initial banking effort, an extensively drained 800+ acre site underlain with hydric soil has been identified in the southeastern quadrant of the GSRA as a potential area for the wetlands mitigation bank. Studies are being conducted to determine the potential wetland restoration acreage within the bank. The Corps of Engineers has noted a willingness to accept the conceptual mitigation banking plan with regard to the construction of the MPTR, and when established, the wetlands impacts will be debited from the mitigation bank. (Corps of Engineers, Wilmington District, letter of 11 February 1994). A potential area of concern associated with the operation of the proposed MPTR is that tank and infantry training activities occurring at military installations with similar physiography to that of the GSRA have resulted in erosion and sedimentation impacts in adjacent wetlands. Mitigation measures, which could include vegetative buffer zones, silt fences, check dams and sedimentation basins, are noted in the present project design (35 percent Design), and a comprehensive erosion control plan would be required as part of the State stormwater certification and construction permit process. 4.1.11 Exemplary Natural Areas The three exemplary natural areas identified within the GSRA (NHP Inventory, Jul., 1993) include the Pocosin Wetlands (two large basins), an area in the vicinity of Padgett Swamp Road, and an area along the South Bay Road (Figure 2-2). Only the Northern Pocosin and the Padgett Swamp Road areas would potentially be affected by the proposed MPTR operations, as portions of these areas lie within the proposed SDZ. Impacts would be the result of spent projectiles (non-explosive) landing in these areas. As observed at other ranges, any damage is expected to be minimal. Benefits resulting from limiting human access and active management and maintenance pursuant to the MCB Camp Lejeune Natural Resource Management plan would, on balance, significantly enhance the long term viability of these sensitive and valuable natural assets. 4.2 Man-Made Environment: Direct Effects and Mitigation Measures Associated with Alternative 1 (Proposed Action) 4.2.1 Land Use and Policies The construction and use of the MPTR is compatible with the Onslow County land use classification currently applicable to the GSRA: Developed/Military Reservation. There are no foreseeable negative impacts or conflicts with county plans or policies associated with the MPTR. 4-8 4.2.2 Demography, Income, and Taxes There will be no permanent impact on the local population associated with the construction or operation of the proposed MPTR. However, since the MPTR would provide local training that presently must be transferred to Fort Knox, Kentucky, the 280 military personnel who would otherwise be sent out of the area for two weeks per year would remain that additional time in Onslow County. Local merchants would benefit. The construction of the proposed MPTR would locally generate a temporary increase in construction jobs and the sale of construction materials. The budget for constructing the proposed MPTR and support facilities is $5.3 million. The type of construction jobs that would be generated are mostly earth moving and carpentry related, and the duration of the construction is anticipated to be approximately 12 months. Subsequently, the installation of the target arrays would occur under a separate budget of approximately $1.3 million. Additionally, the related Highway Department construction of the proposed underpasses for direct access from the main Base to the GSRA would create additional employment. A continuing benefit from the construction and use of the proposed MPTR would be the creation of four permanent civilian range operator and maintenance positions, entailing an annual operations and maintenance budget of approximately $160,000. Activation of the proposed MPTR would, in effect, result in the reduction of potential timber acreage within GSRA. The maneuver area and the ordnance SDZ fan-impact area, amounting to approximately 6,600 acres, would be removed from timber management. Thi ld s wou reduce the future timber harvest and could have a limited impact on local logging crews which would otherwise possibly receive employment. Conversely, owners of stumpage elsewhere in the locale would benefit by increased prices and competition for their products. There are no discernible impacts on the local tax base related to the construction or operation of the proposed MPTR, beyond the impacts associated with the prior purchase by the Federal Government and removal from the county tax base of the 41,100 acre tract (See DEIS, Vol. I, p. IV-26). 4 2 3 Utiliti /I f . . es n rastructure Electricity The proposed MPTR would require electrical power for range equipment, lights, communication, and heat pumps. The regional overhead 12.47 KV electrical distribution line passing through the proposed MPTR site from north to south is scheduled to be relocated to the east of the site, parallel to U.S. Highway 17. This electrical line would be used to supply primary power to the range site. A pad mounted transformer would be installed and both underground distribution lines and overhead lines would be used to connect the automated targets and other support facilities (Planning Branch, Public Works Office, MCB Camp Lejeune; 35 percent Design Plans). As with the movement of a se t f f h gmen o one o t e power lines located in the northwest quadrant of the GSRA (See, DEIS IV-28 for a discussion of the rerouting of the western power line), movement of a segment of the eastern power line closer to the perimeter of the GSRA and away from potential interference with planned training evolutions is being accomplished 4-9 independent of the proposed construction of the MPTR. Requisite environmental investigation and documentation is being accomplished separately for that project. Water The proposed MPTR would require water for drinking, head facilities, local fire fighting, and emergency medical aid. Plans anticipate the digging of a well and construction of a chlorine treatment, storage, and distribution system on site. No impacts on local water supplies or water quality are foreseen. State permits would be required for siting and digging the well. (See section 4.6, Permits) Wastewater During construction of the proposed MPTR, portable toilets would be used. Any chemical toilet waste generated would be disposed of by the contractor in an approved method. The plans for the proposed MPTR include permanent toilet facilities designed to service 270 people per day. Sewage is expected to be handled by a septic tank and leach field system on site. As noted above, poor soil percolation and the high water tables that are characteristic of 75 percent of GSRA may present problems in securing a construction permit for a septic system to support the proposed MPTR site. If soil tests preclude a permit, the Onslow County Land Use Plan recommends the use of package treatment plants or innovative treatment and disposal systems such as low pressure, modified sites, or artificial wetlands (Onslow County Planning Department, 1992 Land Use Plan). The option to construct a sewer line to MCB Camp Lejeune is another alternative which is contained in the draft GSRA Master Development Plan. Should a construction permit not be available for a septic system, the noted alternatives would ensure no adverse impacts from wastewater would occur. Telephone Telephone service is required for the proposed MPTR. Plans for telephone service to the proposed range include extending the fiber-optic line that now runs from New River to the Verona Loop area of MCB Camp Lejeune across U.S. Highway 17 at Moores Ridge Road to the range headquarters building. A buried telephone cable would be installed to connect the proposed MPTR with the range headquarters control box. No adverse impacts are foreseen from the telephone connections. 4.2.4 Ground Traffic The proposed MPTR would cause increased road traffic in the local area during the construction phase and later, to a lesser extent, during range operations. During the construction phase, construction fill dirt, gravel, and other construction materials would have to be trucked to the proposed site. The greatest impact would come from the fill dirt requirement which would be trucked from a borrow pit in the Verona Loop area of MCB Camp Lejeune. An estimated 70,580 cubic yards of fill, entailing 6,000- 10,000 dump truck loads (depending on truck size), would have to cross U.S. Highway 17 from MCB Camp Lejeune to the Reys Road entrance to the GSRA. Other construction material deliveries would use local highway routes. During construction, customary signage and flagmen, in conjunction with scheduling to avoid undue impacts during high local traffic times, should be initiated. 4-10 ?j `J Should the MPTR b ecome operational, traffic impacts would be significantly reduced. For tank crew qualification training, the anticipated range usage would be two days per week for 26 weeks per year (four days per month). That would entail the delivery of two tanks and approximately 22 personnel to the proposed MPTR for the training evolution. Two tractor trailers for the tanks and two trucks for the troops would be required. Initially, the tanks would be trucked to the range using public highways, but long range plans call for direct access from MCB Camp Lejeune via an underpass, further limiting impacts on local traffic. In addition to the four days per month that the range would be used for tank crew training, it would be used an additional day per week for 50 weeks per year for infantry small arms training. As with the tank training, the traffic impact to transport 35 - 40 infantry personnel and their equipment would be three or four trucks delivering to and returning from the range by public highways. Th is impact would cease upon completion of the underpasses from MCB Camp Lejeune to the GSRA. As alluded to above, there are two future projects that will improve access to the MPTR and reduce impact on public roads. In conjunction with a State project to widen U.S. Highway 17, the State will construct three underpasses connecting MCB Camp Lejeune with the GSRA. 4.2.5 Air Traffic The liv fi d l e re an aser training planned for the GSRA, including the proposed MPTR , require restricted airspace for safety. An application to the FAA has been filed (19 April 1994) by the Marine Corps requesting a 55.5 square mile, joint/intermittent use, stratified Restricted Airspace covering the GSRA up to an altitude of 17,999 feet MSL. The three proposed strata are: surface to 6,999 feet MSL; 7,000 to 9 999 feet , MSL; and 10,000 to 17,999 feet MSL. The substantive restrictions and mitigation measures contained in the application have been developed and coordinated with the assistance and recommendations of ARTCC Washington Center, Wilmington Approach Control and FAA ATREP, MCAS Cherry Point. As proposed, the airspace over the GSRA would be divided into two sector N th s ( or and South) to provide greater flexibility and allow for less impact on the use of the V-139 Airway. For safe operation, the proposed MPTR would only require the lowest stratification of airspace (0 to 6,999 feet MSL). The airspace restriction would be in place from ground level to 6,999 feet MSL from 0600 to 1800, Monday through Friday. If MCB Camp Lejeune should require additional restricted airspace strata, or additional times beyond the 0600 to 1800, Monday through Friday, it would have to be scheduled at least 30 da s in advanc ith h F y e w t e AA to allow for the publication of a Notice to Airmen (NOTAM). Since the lowest stratification is the one most often activated (0 to 6,999 feet MSL), all altitudes above this level would be available for over-flight of the Restricted Airspace. As noted above, in addition to the vertical stratifications, the Restricted Airspace is also sectored into North and South sections to maximize flexibility. The intent of the subdivisions is to be able to activate only those areas of the Restricted Airspace necessary for training operations. For several hours each week the North sector would not be activated, allowing a minimal diversion to the West of V-139. At other times, when both sectors do not require activation, vectoring around the MCB Camp Lejeune training areas may be accomplished with a minimum of impact on general aviation. On the occasion of aircraft transiting which are unable to overfly, a cease fire would be 4-11 called to allow for the temporary deactivation of the Restricted Airspace during aircraft transit. On rare occasions when other alternatives are unavailable, training operations would be temporarily curtailed and aircraft would be diverted to the East through the Restricted Airspace over the main MCB Camp Lejeune training areas (R5306 D/C). Special consideration has been given to the two small private airports which have some public use airspace which overlaps into the GSRA airspace. Impacts to Sky Manor Airpark to the northwest and Holly Ridge Airport to the southeast would be reduced by exempting peripheral segments of the GSRA airspace from the restricted zone to ensure that continuous access is available to these two airports within a three mile radius, and from ground level up to 1,500 feet MSL. 4.2.6 Noise A noise impact analysis has been conducted for the proposed operations at the MPTR. The operational noise information analyzed pertains to the noise impacts associated with the 120 mm main tank gun, which is the largest weapon proposed to be fired at the MPTR. The following is a synopsis of pertinent operational data regarding the noise impacts of the proposed MPTR: • The range would be active for 120 mm gun firing two days per week, two hours per day, every other week; • Two 120 mm rounds would be fired approximately every 15 minutes for a total of 16 rounds per day; • Seventy five percent of live fire training would be conducted during day time (0700 - 2200), twenty five percent of live fire training would be conducted at night (2200 - 0700); and, • Total 120 mm rounds per year would be 768 (730 day + 38 night). There would be 50 caliber machine gun and small arms fire associated with the tank live fire training, however the noise impacts from these smaller weapons fall within the contours associated with the 120 mm gun and would not create unacceptable impacts beyond the boundaries of the GSRA. Using the EPA approved Day-Night Level (DNL) model noise evaluator, a noise analysis was conducted based on the proposed weaponry (120 mm main tank gun), and the proposed usage of a MPTR located in the northeast quadrant of the GSRA (US Army, 1993 Environmental Hygiene Agency, Bio-Acoustic Div.). In the noise impact model there is a penalty, or bias, against night firing and the noise contours for the various noise- compatible zones are enlarged as the percent of night firing increases. The 75 percent day/25 percent night firing scenario analysis reflects that both sound contours for the noise sensitive land use categories of "normally incompatible" (with residential housing/hospitals - Zone II), and "incompatible" (with residential housing/hospitals - Zone III) would remain within the boundaries of the GSRA (Figure 4-1). 4.2.7 Cultural Resources The MPTR is proposed to be sited in the northeast quadrant of the GSRA and along the eastern margin of the northern pocosin. The Acquisition EIS (DEIS, 1989 Vol. I, Sec. III) predicted that the most probable locations for regionally significant archeological 4-12 • f t t t t F- a 0 w to O as Om d a a U, Z ?w O F- Ncc F- O UZ Q a 2 w in 0 z Q 0 z c o b 0 a) .= m N a a?

A limited Phase I Archeological and Cultural Resource Study of GSRA (historic document/map research) failed to identify any archaeological sites in the vicinity of the proposed MPTR. A Phase IB Archeological Field Survey of the proposed MPTR site was conducted (Louis Berger, Feb.-Mar 1993), but no sites were discovered within the proposed maneuver area or support facility area. Six sites were located, as predicted, to the north of the proposed MPTR maneuver area along the northern margin of the pocosin, generally along the Hicks Run drainage. The North Carolina Department of Cultural Resources, Division of Archives and History, was provided a copy of the Phase 1-13 Survey, and concurred in its conclusions and belief that the construction and operation of the proposed MPTR would have no impact upon these sites. In order to avoid inadvertent or accidental damage during the proposed construction of the MPTR, the six sites would be marked in the field prior to the commencement of any construction activities. A recommendation was made that further investigations at the six sites discovered to the north of the proposed MPTR be postponed awaiting "completion of all survey work in the GSRA to provide optimal contexts for developing evaluative testing plans and site data interpretation." (North Carolina Department of Cultural Resources, letter of 12 August 1993). It has been agreed that this evaluation can be delayed until after commencement of construction of the proposed MPTR, should it be approved. Because the Marine Corps real estate acquisition was not complete within the GSRA at the time of the cultural resource survey of the proposed MPTR maneuver/support facility area, the extreme western portion of the SDZ was not surveyed although the soils would indicate a reasonable potential for cultural resources. Now that acquisition is complete, archeological surveys in that area, which is far removed from the proposed maneuver/support facility area of the MPTR, are scheduled to commence in July 1994. Any discoveries will be coordinated with the SHPO, although no impacts from the construction or operation of the proposed MPTR are foreseen. Associated with the construction of the proposed MPTR would be a construction fill borrow pit in the Verona Loop area of MCB Camp Lejeune. An archaeological field survey was also conducted of this proposed 55 acre tract with no sites discovered (Ogden, Jul., 1993, Appendix D). With regard to cultural resources within the GSRA in general, and the overall plans for military development within the GSRA, a programmatic agreement is being negotiated among the SHPO, the Advisory Council on Historic Preservation, and MCB Camp Lejeune. The programmatic agreement will provide that prior to any actual ground-breaking activities associated with GSRA development, proper cultural resource surveys will be completed in those areas of moderate to high potential for cultural resources which may be impacted by planned development. The results of these future surveys will be coordinated with the SHPO prior to the construction of any proposed ranges or associated training facilities. 4.2.8 Safety Ordnance The proposed MPTR would provide a live fire training facility for the 120 mm main tank gun (using non-explosive Training Practice Rounds), the 50 caliber and 7.62 mm machine gun, the 5.56 mm rifle, and the 9 mm pistol. Other incendiary devices which 4-14 may be used on the range include tracer rounds, smoke grenades, booby-trap simulators, and hand-held illumination. Safety and standard operating procedures (SOPs) exist for these weapons and devices, and site-specific procedures would be developed for the individual range operation, as required by Marine Corps regulations (MCO P3570.1 A/AR 385-63). r Target design, the SDZ, and restricted airspace will be established to provide safe range operations. GSRA presently has "No Trespassing" boundary signs posted every 200 feet prohibiting entry by unauthorized personnel, and prior to range operation, the maneuver area and the SDZ would have additional warning signs, barriers and range guards, as required by Marine Corps regulations (MCO P3570.1 A/AR 385-63). Lasers The standard, unshielded laser range finders on the M1 Al tank can injure the unprotected eyes of individuals viewing the direct laser beam or a reflected beam. A flat, mirror-like surface, such as water or glass, is an efficient reflector, and the eye hazard is maintained for considerable distance. If an individual is using magnifying optics (binoculars), the hazardous distances are increased. The GSRA was recommended as a preferred site for the proposed MPTR because, among other things, there were no large bodies of water or other reflective surfaces similar to those found on MCB Camp Lejeune, and the remoteness of the area further reduced the potential danger to individuals who might inadvertently view a reflected laser beam. The Marine Corps has recently approved the use of a laser filter (ESSLR Eye-Safe Laser Filter, or ELF) to counter the eye hazards associated with the laser range finder. This device is a filter which reduces the strength of the laser so that there is no hazard to personnel in the vicinity. There is a proposal that all laser range finder use at the proposed MPTR will employ the ELF, however, the range of the laser is reduced when it is attached. There may be some training (such as when target acquisition must be greater than 1600 meters) when the ELF would not be used. A laser range certification of the proposed MPTR would be required before laser operations would be authorized. The certification process would review hazards and include mitigation measures that would be required. Laser warning signs and barriers would be placed around the boundary of the range in accordance with Marine Corps regulations (MCO P3570.1A/AR 385-63 and AR 385-30) (See section 4.6, Permits). Range Access Control The acquisition of the GSRA and integration of the tract into MCB Camp Lejeune resulted in the exclusion of the general public from what is now a military reservation. The proposed construction of the MPTR does not alter the prohibited access to the area. Requisite signage, barricades and patrols should be provided to ensure public awareness and safety. 4.2.9 Contamination No existing contamination has been discovered within the vicinity of the proposed MPTR and support facility area. Additionally, since there would be no vehicle maintenance, other than emergency repair, and no vehicle or tank washing conducted on the site, there exists little probability that any significant environmental contamination would be a 4-15 factor at the MPTR. However, a normal operation associated with vehicles which has the potential for contamination is the filling of fuel tanks. If fueling vehicles on site becomes a requirement, this procedure would require planning and the development of a spill response plan for the proposed MPTR. No surface water contamination is expected as a result of the non-explosive ordnance (steel or copper-jacketed) usage at the MPTR. 4.3 Direct Effects and Mitigation Measures Associated with Alternative 2 (No Action) The No Action alternative amounts to a continuation of the status quo, with a continued dependence on off-base ranges such as Fort Knox, Kentucky for tank crew qualification training. Any impacts upon the natural or man-made environments from a No Action determination would result, generally, from the additional training evolutions and transportation activities associated with transporting men and materiel to the off-base facilities. Because the No Action alternative entails no new construction, only minor physical impacts to the natural environment (See, sections 4.1.1 through 4.1.11 above for categories of concern) would be felt at off-base locations. Existing natural resource management programs at the off-base training facilities are assumed to be adequate to handle the added training pressures that MCB Camp Lejeune must now export. Regarding impacts to the man-made environment (See, sections 4.2.1 through 4.2.9 above for categories of concern), the existing training facilities at any off-base sites to which the tank crews are sent would be capable of assimilating the MCB Camp Lejeune training requirements with only minor operational impacts. Ground traffic associated with the off-base movement of tanks and personnel, and the added noise generated during the training, are the two areas in which the most impact would be realized, however, these impacts would be minor. In summary, all existing impacts associated with the status quo (the No Action alternative) are believed to be minor and within the design capacity of the receiving facilities. 4.4 Cumulative Impacts A regional analysis was conducted of the potential cumulative effects of Department of the Navy and Department of the Air Force proposals on the coastal region of North Carolina. This analysis is contained in the Acquisition EIS (See, DEIS, Vol. II, and FEIS, Appendices B and C), is broad in scope, and addresses the socioeconomic, safety and environmental effects associated with the existing and proposed military facilities, including air and surface water training areas, on, above, and adjacent to the coast of North Carolina. This analysis focuses, to a large extent, on the impacts of restricted airspace and aircraft noise on the North Carolina coastal region, but it also includes the (then proposed) expansion of MCB Camp Lejeune through the purchase of the GSRA. The cumulative effects analysis in the Acquisition EIS determined the regional socioeconomic, safety and natural environmental baselines, but recognized that specific future projects, before they could proceed, would require the collection of additional data, focused analysis, and then specific decisions respecting project design, modification and/or mitigation measures to minimize negative impacts. This EA, as a follow-on document to the parent document in a tiered process, analyzes the Proposed Action, and 4-16 l bl f l a so reasona y oreseeab e actions associated with the development of the GSRA, within the context of that regional perspective. B i h A i i i EIS l i y us ng t e cqu s t on cumu at ve effects methodology to measure the impacts associated with the expansion of MCB Camp Lejeune through the acquisition and development of the GSRA (both the Proposed Action and reasonably foreseeable actions), the important issues can be organized and analyzed. It must be noted, however, that many of the "reasonably foreseeable actions" of today are in the conceptual stage and may or may not come to fruition for any number of reasons, including the uncertainties of the government funding process or the results of the environmental analysis. Additional study will be required as the various proposals to develop the GSRA go forward. In assessing the regional cumulative effects, the Acquisition EIS discussed the following impacts/issues which pertain to the development and use of the GSRA, and this EA has added two additional impacts/issues - weapons-related noise and cultural resources - for consideration and analysis: Generation of Jobs. A recognized positive cumulative effect of the military presence in the region is the creation of jobs, and an indirect benefit to the regional retail economy. The Proposed Action (MPTR) would create a number of temporary construction jobs, if built, and would employ four full-time range attendants if completed. The draft Master Development Plan for the GSRA foresees the construction of up to nine additional ranges, and the creation of jobs (number unknown), both temporary and permanent, would have similar positive regional cumulative aspects. Perception of Loss of Airspace. The Acquisition EIS (DEIS, 1989, Vol. II, Sec. VIII) notes that a negative socioeconomic impact may be created by a misconception among some commercial or recreational aircraft pilots that all Military Special Use Areas (MSUAs which include Military Operating Areas (MOAs) and Restricted Areas) must be avoided at all times, and that any additional MSUA represents an incremental total loss of available airspace for civilian travel. A dominant impact associated with the proposed MPTR, and the other foreseeable development for the GSRA, is the requirement for restricted airspace to allow for live fire training and laser range finder use. The airspace requirement for the proposed MPTR, as previously discussed, and for future development of additional GSRA ranges, would normally be from ground level to 6,999 feet MSL. This 6,999 foot requirement is based on the fact that no indirect fire weapons (artillery, mortars) are currently planned for use in the GSRA. However, if indirect fire weapons should be introduced into the GSRA training scenario, additional strata of restricted airspace would be required, and eventually could require up to 17,999 feet MSL above the GSRA. While the negotiations with the FAA regarding the establishment of an additional restricted airspace for the GSRA operations have concentrated on mitigation measures to lessen the negative impacts on the coastal North Carolina area, there will be, nevertheless, an increase in the existing negative regional impact associated with restricted air space. Potential for Aircraft Collisions/Crashes. While the Proposed Action (MPTR) has no potential for aircraft collisions/crashes, the planned construction of another, larger multipurpose range complex in the future, which would include the addition of one low- level helicopter operating with tanks and infantry, would provide a potential for such an event. Public concern about collisions/crashes is considered to be a regionally 4-17 significant indirect negative cumulative impact, although the location of any potential crash would be in the interior of the GSRA, and the fact that civilian aircraft would be excluded from the area during training would reduce the actual danger to the civilian community. The added cumulative impact would be small. Control of Airspace and Public Safety. The increased safety resulting from the charting of any restricted airspace associated with the Proposed Action (MPTR), and subsequent GSRA development, is considered to be a direct positive regional cumulative impact. Aircraft Noise. The Proposed Action (MPTR) would present no aircraft noise impacts, however, there would be some low-level helicopter flights associated with the planned development elsewhere in the GSRA. As noted above, the additional aircraft noise would be associated with one low-level helicopter operating with tanks and infantry on the ground, and though minor, it would amount to an additive cumulative impact. Until a range design and associated data regarding the localized impacts of the potential aircraft noise are developed, aircraft noise cumulative impacts cannot be accurately stated. However, it is Marine Corps policy to avoid or mitigate to the maximum extent possible any adverse effects associated with training operations. Weapons-Related Noise. A cumulative noise impact study was conducted by the US Army Environmental Hygiene Agency, Bio-Acoustics Division, for the entire GSRA, including the anticipated training regimen of the proposed MPTR and for an array of nine future ranges which may be subsequently constructed within the GSRA (Figure 4-2). This analysis incorporated two major decisions affecting the noise picture for the planned GSRA development: the first is that no indirect-fire weapons (artillery/mortars) would be utilized within the planned GSRA range complex; the second is that no explosive ordnance would be fired. These decisions have effectively erased the noise concerns stated in the Acquisition EIS (See, FEIS, Appendix A) which centered on the impacts of artillery and mortar positions sited very close to the boundary of the GSRA. Additionally, without explosive ordnance being used, the effect of secondary explosions associated with ordnance impact areas is also eliminated. The cumulative noise analysis does not change the anticipated noise impacts of the proposed MPTR. For noise associated with the proposed MPTR, neither the noise contour for Zone II (Normally incompatible with residential/hospital land use) nor Zone III (Incompatible with residential/hospital land use) extends beyond the boundary of the GSRA. Additionally, the noise analysis for the entire GSRA, based on the present GSRA future development concept, shows that the noise contours for Zones II and III remain within Marine Corps property. In the northeast quadrant of the GSRA, the Zone II contour line does extend over U.S. Highway 17, however, the property on both sides of the roadway in that area is Marine Corps property and not available for residential use. In any event, however, there will be an increase in cumulative negative impact as a result of creating additional noise sources within the GSRA, and it must be considered a direct, negative regional cumulative effect. Protection of Endangered Species. Regarding the Proposed Action (MPTR), no Federally endangered or threatened species impacts are anticipated, although there is the potential that some Federal Candidate species may be affected. There is a requirement to confer with the USFWS regarding these impacts. With respect to future development elsewhere in the GSRA, and the additional ranges and facilities that may be built, there will be a requirement to accurately identify and assess the potential impacts of the planned ranges 4-18 m m= r r= m m r r m= r r m== w w and facilities. Appropriate consultations/conferences would be conducted with Federal authorities to develop appropriate mitigation measures. Despite the localized negative impacts that would result from the planned development of the GSRA (ranges, roads, etc.), the overall positive effect on numerous rare species through habitat creation, management, and maintenance would prove to be a net positive cumulative effect. In fact, the protection and management afforded endangered species on military installations is nationally significant and is considered a direct positive regional cumulative effect. Wetlands. Based on the recent wetlands delineation (Spring 1994) conducted in the northeast quadrant of the GSRA to enable an informed siting and range design for the MPTR, it is estimated by the Corps of Engineers that approximately 25 acres of wetlands will be impacted by the construction of the range. In choosing the site and actual range design (placement of roads and targets), maximum avoidance of wetlands was a driving factor in the process. In conjunction with the development of the GSRA for military use, a wetlands mitigation banking program is being established, and some of the previously altered or damaged wetlands which suffered as a result of the prior timber management in the GSRA will be restored. The wetlands impacts associated with the MPTR would be mitigated through the use of the wetlands mitigation bank at a minimum of a 2:1 mitigation ratio. Nevertheless, the Acquisition EIS recognized that even if the filling of wetlands is mitigated to the maximum extent practicable, the filling of wetlands is considered regionally significant because of the national importance currently afforded wetlands preservation. The fill of any wetlands is considered a direct negative regional cumulative effect. For the future development of the GSRA, it is recognized that there will be unavoidable wetlands impacts connected with the anticipated development and construction of other ranges elsewhere in the GSRA, but the true amount of wetlands which will have to be filled will not be known until actual range designs are completed and a site-specific analysis of delineated wetlands is conducted. Overall GSRA development will be planned and operated with the underlying policy of avoidance of any wetland impacts, if possible, and mitigation to the maximum extent when avoidance is not possible. Close coordination with the U.S. Army Corps of Engineers and the State of North Carolina will be accomplished. Exemplary Natural Areas: The State of North Carolina, Department of Environment, Health, and Natural Resources (DEHNR), Natural Heritage Program (NHP) prepared a comprehensive inventory of rare species, natural communities, and critical habitats of the entire GSRA (NHP Inventory, Jul., 1993). Few high quality, little-disturbed natural communities remain in the GSRA as a result of the previous timber operations. However, three exemplary natural areas within the GSRA of sufficient size and quality to be recommended for special attention and protection were identified. These areas are the Pocosin Basins (north and south), an area in the vicinity of Padgett Swamp Road, and an area in the vicinity of the South Bay Road. While portions of the northern pocosin and the Padgett Swamp Road area fall within the SDZ fan associated with the proposed MPTR, any measurable impact or damage in these areas from training operations at the proposed MPTR, including damage from spent projectiles, is considered extremely remote. In fact, the overall cumulative effects of MCB Camp Lejeune's natural resource management program respecting these three relatively undisturbed areas is believed to be positive. Limited human access and positive resource management should contribute 4-21 to the long term viability of these natural areas and is considered a direct positive regional cumulative effect. Cultural Resources. Cultural resource surveys have been completed for the Proposed Action (MPTR), including a construction fill borrow pit area, with negative results. Any other development within the GSRA would also be preceded by required cultural resource surveys. A Programmatic Agreement among MCB Camp Lejeune, The Advisory Council on Historic Preservation and North Carolina State Historic Preservation Officer (SHPO) is under preparation. This Programmatic Agreement will ensure that a cultural resource survey is conducted of potentially affected areas prior to the commencement of any land disturbing activities. The protection and management afforded cultural resources on military property is nationally significant and considered a direct positive regional cumulative effect. 4.5 Possible Conflicts with Federal, State, Local Land Use Plans, Policies and Controls A thorough analysis of possible conflicts with Federal, State and local laws, plans and policies concerning not only the acquisition of the GSRA, but also for the stated purpose of expanding the MCB Camp Lejeune training mission into the tract, is contained in the Acquisition EIS (DEIS, Vol. I, IV-36). The MPTR impacts are consistent with the development concept and planned uses included in that analysis, and it has been determined that no such conflicts exist. 4.6 Permit Requirements and Agency Approvals 4.6.1 Wastewater If the Marine Corps chooses to pursue installation of a wastewater system utilizing subsurface ground absorption (leach fields), then a permit would be obtained from the North Carolina Division of Environmental Health, On-site Wastewater Section. All non municipal facilities treating domestic wastewater with design flows of 100,000 gallons per day (GPD) or less are required to pay a $75.00 application processing fee. Additionally, the Marine Corps would submit a soil evaluation of the disposal site conducted by a soils scientist to adequately evaluate the soils to be utilized for treatment and disposal down to a depth of seven feet; submit plans of the complete system including plan and profile and cross section views for all relevant system components; provide a map of the site, with topographic contour intervals not exceeding two feet, and showing all structures and wells, springs, lakes, ponds, or other surface drainage features within 500 feet of the site; and, information on the location, construction, and primary usage of all wells within 500 feet of the site, and the degree of treatment. 4.6.2 Point Source and Stormwater Permits In the state of North Carolina, permits are required from the State for any stormwater discharges associated with industrial activity. Runoff not meeting the definition of "associated with industrial activity" may require permits if the Director of the North Carolina Division of Environmental Management determines that water quality standards may be violated. All state fresh surface waters are subject to standards that apply to Class C (protected for secondary recreation, fishing, and aquatic life including 4-22 propagation and survival) waters. This requirement includes the presence of high levels of dissolved solids. Due to the activities which could be expected to occur on the GSRA, both stormwater and flow discharge from the proposed MPTR areas may require National Pollutant Discharge Elimination System (NPDES) permits and monitoring to ensure that off-site surface water quality will not suffer degradation due to the introduction of contaminants and silt generated by training activities. Because the proposed MPTR, and also the construction fill borrow pit, would entail construction and disturbance of more than five acres (technically an "industrial activity"), a construction permit would be required from the State. Also, because Onslow County is one of the coastal counties of North Carolina, an added State Stormwater Certificate would be required if construction in the proposed MPTR area creates more than one acre of impervious surface . 4.6.3 Drinking Water/Wellhead Protection The construction of water wells is regulated by the state of North Carolina. Prior to installing a drinking water well anywhere within the GSRA, the Marine Corps would obtain a construction permit from the Wilmington Regional Water Quality Office of the Division of Environmental Management. The Regional Water Quality Office will need to know what the well's intended purpose is, expected volume required, and other physical data. This information would be provided in a construction permit application and submitted to the regional office. 4.6.4 Wetlands Based upon the wetlands delineation of the proposed MPTR site, the Corps of Engineers estimates that approximately 25 acres of wetlands would be affected. This will require the issuance of a Section 404 permit through the Corps of Engineers. The Section 404 permit is required whenever there is discharge of dredged or fill material into wetlands or navigable waters. Under the Clean Water Act, the discharge of dredged or fill material means the addition of fill material into U.S. waters, and includes placement of fill that is necessary for the construction of any structure or impoundment requiring rock, sand, dirt, or other materials for its construction; site development fills for various uses; causeways or road fills; and dams or dikes. Prior to applying to the Army Corps of Engineers for a Section 404 permit, the Marine Corps would first obtain a Section 401 Water Quality Certification from North Carolina. State certification ensures that the proposed activity or conduct will not result in discharges that may adversely affect U.S. navigable waters, and that all proposed activities will comply with applicable provisions of the Federal Clean Water Act and State standards. 4.6.5 Restricted Airspace FAA approval is being sought for restricted airspace above the GSRA. 4.6.6 Laser Range Certification Certification of the proposed MPTR as a laser approved range would be obtained through the Department of the Navy, Space and Naval Warfare Systems Command. 1 4-23 4.6.7 Federally Endangered/Threatened Species With respect to Federally listed Endangered or Threatened species (i.e., rough-leafed loosestrife), potential adverse impacts require consultation with the USFWS pursuant to Section 7, Endangered Species Act. This has been accomplished with regard to the rough- leaved loosestrife, and a letter from the U.S. Fish and Wildlife Service (USFWS letter of 15 November 1993) indicates concurrence with the opinion that the construction of the proposed MPTR would have no effect on known locations of the Federally listed plant, and that through active fire control, the Marine Corps' operation of the proposed range is not likely to adversely affect the plant. If a proposed action is likely to jeopardize the continued existence of a Federal Candidate protected species, or one proposed for candidacy, or result in the destruction or adverse modification of the species critical habitat, the USFWS must be conferred with. Unlike the formalized consultation process, Federal agencies are not prohibited from making irretrievable commitment of resources once beginning the conferring process. A conference generally consists of informal discussions resulting in the USFWS making recommendations on appropriate agency actions. 4-24 1 5.0 DATA SOURCES Army Environmental Hygiene Agency, 1990, Quantifying Environmental Noise Through Automated Monitoring: Case Studies from US Military Community, Mannheim, Germany (draft).

This land was acquired to provide an area for the expansion of existing training facilities at MCB Camp Lejeune. Various ranges and other training related facilities are proposed to be constructed throughout the GSRA property. Substantial amounts of fill material will be required for roads, parking lots, berms, and other uses as part of the planned GSRA development. It is estimated that approximately 1,000,000 cubic yards of fill material may ultimately be required to support full development of the GSRA. At this stage in the planning process, however, only about 500,000 cubic yards of material is required. This study is part of an effort to identify a source or sources of fill material which will meet the near-term needs of GSRA development. Preliminary borrow pit site selection was conducted by Avolis Engineering, P.A. in November, 1992, and documented in the Preliminary Report. Borrow Pit Site Investigation for Greater Sandy Run Area. Engineering Study 92-33 (henceforth, "Preliminary Report"). The siting selection criteria specified that the borrow pit(s) be located in the Verona Loop area of MCB Camp Lejeune, and that impacts to training areas, wetlands, archaeological and historic resources, and endangered and threatened species be minimized. The Verona Loop area was chosen as a general location for potential borrow material because it is located adjacent to the GSRA, is part of MCB Camp Lejeune, and is currently used as a Marine Corps training area, thus minimizing potential human conflicts. The Preliminary Report identified a 55 acre site, known as Site #5 in the Preliminary Report, adjacent to Haws Run Road in the Verona Loop training area of MCB Camp Lejeune (Fig. 1). Site #5 is estimated to contain approximately 532,000 cubic yards of suitable fill material, and was chosen by MCB Camp Lejeune engineering staff as a 1 primary site for further evaluation as a borrow material source for GSRA. 1.2 Project Objective This biological survey was conducted to provide additional data regarding the environmental suitability of Site #5 for use as a borrow pit for GSRA development. The specific objectives of the survey were as follows: • Generally characterize the vegetative cover of the proposed borrow pit site; • Determine the presence or absence of Federal/State threatened or endangered s ecies or the existen f it bl h bit t t t th i d p ce o su a e a a o suppor ese spec es; an , • Locate environmentally sensitive areas, such as wetlands, within the site. O i f part cular concern to the study are the federally protected red-cockaded woodpecker (Picoides borealis) and rough-leaved loosestrife (Lysimachia asperulaefolia) which are both known to be present on Camp Lejeune.

N E am 0 Z ui 6 m Q m ? o m N CD > C m CL 3 0 t m 0 rJ 2.0 METHODOLOGY 2.1 Description of the Project Area Site #5 is composed of relatively flat, well-drained forested terrain characterized by the presence of low hills, ridges and uplands 5 to 15 feet higher in elevation than surrounding areas. Elevations vary from 50 to 70 feet above mean sea level (MSL) over the site. The highest elevations are on the southwest side of the site. The majority of the site is composed of relatively dry pine forest and pine-hardwood forest stands. According to the U.S. Fish and Wildlife Service, National Wetlands Inventory (NWI), (Avolis 1992), jurisdictional wetlands are located at both the north- west and south-east boundaries of the site. These known wetland areas are identified by the NWI as Palustrine Forested Wetlands. Palustrine systems consist of all non-tidal wetlands dominated by trees, shrubs and mosses and/or lichens. The most recent preliminary soils mapping (Avolis 1992) indicates that Site #5 is situated within an area of predominantly Baymeade (BmB) soil type. The borehole log from the Preliminary Report indicates a 6-foot depth to ground water. BmB soil is identified by the USDA Soil Conservation Service (SCS) as "good" for road-fill, meaning that it contains a significant amount of sand (at least 5 feet of material), has a slope of 15% or less, and a depth to a water table of three feet or greater (US Dept. of Agriculture 1984). Erosion hazards are listed as slight, but shallow excavations or cut-banks are prone to caving. The SCS survey also indicates that BmB is "very poor" habitat for wetland plants and wildlife. No biological surveys specific to the site have been conducted prior to this survey. 2.2 Field Survey Methods Following a vehicle tour of the area surrounding Site #5, the survey was initiated by establishing a grid demarcated with surveyor tape and stakes to provide site orientation and boundary limits. The grid was designed to provide access to the interior of the site, and to support surveys of vegetation, wildlife, and potential wetland resources. The first line of the grid to be established was an east-west transect running the width of the site. This mid-line was consequently intersected by the placement of five north- south transects, identified as lines A, B, C, D, and E, that extend from the Haws Run access road to the northern bounds of the property (Fig. 2). Transecting points indicated on the mid-line were demarcated at intervals of 220 meters with the exception of line E which transected the mid-line 150 meters east of line D. The five north-south transects ranged from 150 to 450 meters in length. The survey team used a compass to obtain an east-west bearing for the mid-line and a north-south bearing for transects A, B, C, D, and E. Measured intervals were recorded along the A-E mid-line to determine location. The distances of intervals recorded depended on the density of the underbrush and the ability to maintain bearings. (A machete was used to clear some areas of particularly thick undergrowth, facilitating the surveying process.) Stakes were driven at the beginning of the line and at the 220, 3 Q 1Q0 2r 3i 400 500 l I Scale in Meters FIGURE 2 BIOLOGICAL SURVEY GRID 440, and 660 meter marks. Measured intervals were also recorded during the north- south transects to determine total distances, either south to the Haws Run Road or north to the northern boundary of the parcel. 2.2.1 Vegetation Survey Methods The next stage of the study involved both qualitative analysis and quantitative sampling of vegetation at the site. Results obtained from the sampling provided a general listing of plant species, an evaluation of habitat suitability for threatened and/or endangered species, and a preliminary identification of potential wetland communities. The biological survey team member began the vegetation survey by walking the entire length of the previously established grid, recording changes in vegetation and establishing communities of individual vegetative stands. This type of vegetative analysis is known as the releve' method (Mueller-Dombois 1974). Releve', or sample stand" analysis, provides a systematic record of data designed to assist in grouping vegetation into categories. The releve' record kept during the field survey provides three basic types of information: • COMMUNITIES IDENTIFIED (Representative communities encountered during the biological survey): Loblolly/Longleaf nine forest: Dominated by loblolly pine (Pious taeda) in the overstory and highbush blueberry (Vaccinium corymbosum), fetterbush (Lyonia lucida), and wax myrtle (Myrica cerifera) in the understory. Pine-Hardwood Forest: Occurs between the hardwoods associated with bottomlands and the pure upland stands of pine. Dominant vegetation includes loblolly pine and longleaf pine (Pious australis) with laurel oak (Quercus laurifolia) and red maple (Acer rubrum) in the canopy, and wax myrtle and blueberry in the shrub layer. Hardwood Bottomland Forest: Potential wetland area. Rich, moist community of red maple, willow oak (Quercus phellos) and live oak (Quercus virginiana) in the canopy, and titi (Cyrilla racemiflora), fetterbush, ferns (Woodwardia ssp.) and sphagnum moss (Sphagnum ssp.) are present throughout the understory. Cleared Areas: The result of previous logging activities, or discontinued roadways. Some scattered pine and/or hardwood, but generally dominated by grasses, sedges, and various ericaceous plants such as blueberry and gallberry (11ex glabra). • STRATUM CATEGORIES (Vertical classification): -Tree layer, any plant taller than 5 meters. .? -Shrub layer, plants between 30 centimeters and 5 meters tall. -Herb layer, from <30 centimeters to 1 meter tall. • COVER AREA ESTIMATIONS (Species cover or abundance): -Greater than 75% of sample area -50-75% coverage of sample area -25-50% coverage of sample area -5-25% coverage of sample area -Numerous, but less than 5%, or scattered with cover up to 5% -Few, with small cover -Solitary, with small cover Once the communities encountered on-site were identified, a second field procedure was conducted to enable the team to estimate the cover-area of each community within the borrow pit site. Vegetation noted within a 25 meter-wide "belt" along the survey grid was then categorized and placed within a specific community identified by the predominant canopy species, and meeting particular criteria based on understory vegetation (Fig. 3). These categories and criteria were established during the releve' analysis. For instance, if loblolly pine and longleaf pine dominate the tree stratum (or layer) and blueberry plants are scattered throughout the shrub stratum, the community would be characterized as loblolly/longleaf pine forest. General qualitative sampling within a belt along a transect is a modification of the Belted Transect Survey which is the most commonly used method of sampling forested sites. To obtain a representative sample of plant species within each vegetative community identified by the releve' analysis, additional sampling was conducted in sites randomly selected along the grid (Fig. 4). The communities in each of the six sites were identified, a general inventory of species recorded, and an approximation of each species' abundance noted. The species list also included the stratum at which each plant was most likely to occur (i.e., tree, shrub, or herb layer). Areas of potential wetlands were identified during the releve' analysis process and the belted transect survey based on vegetative properties, soil characteristics, and evidence of flooding frequencies. Indications of standing water, wetland vegetation, or saturated soil were recorded and mapped using the formerly established grid of transects for orientation. The data was then used along with available aerial photography to develop a cover map (Fig. 5). 2.2.2 Wildlife Survey Methods The final phase of the study involved the establishment of seven wildlife observation stations along the previously surveyed grid pattern of transects (Fig. 6). These stations were quietly attended in an effort to identify wildlife present, and to determine if threatened or endangered animal species might inhabit the site. Observation points were plotted based on data gathered during the vegetation survey. The vegetative survey identified communities that could potentially be utilized by the red-cockaded woodpecker or other species of special interest such as the black bear (Ursus americanus). 6 ¦ t w 11 r • Q 1f0 2r 3r 410 510 l Scale in Metiers I I FIGURE 3 MODIFIED BELTED TRANSECT SURVEY 0 100 2i 300 400 500 l Scale in Meters FIGURE 4 VEGETATION SAMPLING • F-1 s E t t 100 2i 3i 400 500 FIGURE5 Scale in Meters VEGETATIVE COMMUNITIES 6 6 17 d C @4 70 G,y 90 ?o LEGEND WILDLIFE OBSERVATION STATIONS ® BEAR SIGN TURKEY SIGN ® POTENTIAL RED-COCKADED WOODPECKER HABITAT ROAD O FOOD PLOT SITE #5 BOUNDARY 5 /60 D 65 t A?? qp) 65 1Q0 2r 3i 400 500 If Scale in Meters FIGURE 6 WILDLIFE OBSERVATION SURVEY t 11 Each wildlife observation station consisted of an individual tree marked with surveyor flagging which indicated the assigned station number. Station size was determined by the visibility and acoustics each site offered. The stations were set up at random intervals along both the east-west mid-line and north-south transects. Each observation point was attended for a period of no less than fifteen minutes. Data collected was based on visual observations, assisted through the use of binoculars, and auditory indicators (e.g., bird calls). 3.0 SURVEY RESULTS 3.1 Vegetation Results from the vegetative survey of Site #5 determined that the parcel is composed primarily of the following communities: loblolly-longleaf pine forest, pine-hardwood forest, hardwood bottomland forest and cleared areas. The majority of the site is composed of the loblolly/longleaf pine forest (approximately 45%) which is dominated by loblolly pine (Pious taeda) in the overstory and highbush blueberry (Vaccinium corymbosum), fetterbush (Lyonia lucida), and wax myrtle (Myrica cerifera) in the understory. The second largest community (approximately 40%) identified during the study is the pine-hardwood forest. This community occurs between the hardwoods associated with bottomlands and the pure upland stands of pine. Dominant vegetation includes loblolly pine and longleaf pine (Pious australis) with laurel oak (Quercus laurifolia) and red maple (Acer rubrum) in the canopy, and wax myrtle and blueberry in the shrub layer. Approximately 3 acres (roughly 1 hectare) or 5% of Site #5 is hardwood bottomland forest. This community represents the only potential wetland area encountered during the survey. The biological survey occurred during unseasonably dry weather and available evidence (depressions in the forest floor exposing thick organic soil) indicated that standing water may at times be present at certain locations in this community. red maple, willow oak (Quercus phellos) and live oak (Quercus virginiana) dominate the canopy of the hardwood bottomland forest, and titi (Cyrilla racemiflora), fetterbush, ferns (Woodwardia ssp.) and sphagnum moss (Sphagnum ssp.) are present throughout the understory. Cleared areas comprise a relatively small portion of the entire parcel (approximately 10%). The majority of the clearings are located adjacent to the access road and are generally an acre or less in size. Previous logging activities or discontinued roadways created these openings in the forest cover. One of these clearings, known as the "L- shaped Food Plot", is located in the southeast portion of the site, and occupies approximately three acres of the total parcel. This area was re-seeded with grasses and various forbs, and is currently being maintained as a wildlife forage area by MCB Camp Lejeune Environmental Management Division staff. Threatened/Endangered Flora Results obtained from the vegetative survey indicate that very little habitat exists to support Federal and/or State threatened/endangered plant species. The Federally 11 endangered rough-leaved loosestrife requires open savanna areas, particularly roadsides and powerline rights-of-way. Three roads ("North", "Mid" and "South"), that access the property from the Haws Run road and pass east-west through the site dividing it into thirds, could potentially provide suitable habitat to support the rough-leaved loosestrife, though no individuals of the species were located. Several venus flytrap (Dionaea muscipula) plants and an unidentified species of Yellow-eyed Grass (Xyris ssp.) are located approximately 110 meters west along the North Road from the Haws Run Road junction (Fig. 4). The State of North Carolina recognizes the carnivorous venus flytrap as a candidate for Special Concern listing due to global rarity, unauthorized seizures, and horticultural distributions. Though the yellow-eyed grass recorded was not further identified, two of the species of this grass are protected by the State with a Special Concern listing and a third is a candidate for listing. 3.2 Wildlife Due to the height of the shrub-layer, size of the parcel, and the density of the underbrush that effectively limited the usefulness of binoculars, the majority of the observations recorded were based on auditory evidence or visual indicators closer to the ground, such as deer browse and/or tracks. Several species of birds common to the area were heard calling during the survey. Various woodpeckers (Picidae family), such as red-headed and pileated woodpeckers, were recorded as foraging and calling, predominantly in the pine forest communities, however, signs such as pecking holes and wood-chip piles were present throughout the entire parcel. During the initial transect survey of the north-south line C, an immature turkey (Meleagris gallopavo), which is a bird not particularly common to the area, was observed roosting in an oak tree (Fig. 6). Also noted during the survey of line C, was a hanging nest similar to that of an orchard oriole's (Ictercus spurius). Deer sign was apparent at several of the observation stations, particularly at the station in the hardwood bottomland forest. Black bear (Ursus americanus) scat was also located along the A-E mid-line in the bottomland community, approximately 50 meters west of stake B (Fig. 6). Another observation recorded in the survey indicated that large mammals appear to utilize former fire lines as travel corridors to pass more easily through the dense understory of the site. These fire lines are associated with the previous forestry management practice of using trenches to slow the spread of fires that frequently occur in the pine forests. These fire lines (generally no greater than one meter wide) also provide habitat for various wetland plants such as sedges, mosses and carnivorous sundew (Drosera ssp.), which were recorded as growing in a fire line crossing the north-south transect "E". The absence of longleaf pine tree cavities (either active or inactive) and a lack of actual sightings indicate that the red-cockaded woodpecker does not inhabit the proposed borrow pit site. However, the relatively mature loblolly/longleaf pine stand located at the southeastern portion of the site is similar to the delineated foraging areas for known colonies, located approximately 1 mile southeast of the site (Fig. 7). 12 t t A 1 t t 1 1 t t t t LEGEND ROAD RED-COCKADED WOODPECKER HABITAT CIRCLE BORROW PIT VERONA LOOP ROAD FIGURE 7 o 4,000 wat.n KNOWN RED-COCKADED WOODPECKER TERRITORY Source: MCB Camp Lejeune, Environmental Mgt., 1993 3.3 Wetlands Site #5 is predominantly comprised of upland forested areas, however, typical wetland vegetation, evidence of previous standing water, and moist, deep organic soils were encountered along the A-E mid-line at the 125 meter mark (see Fig. 4). These wetland indicators are present throughout the hardwood bottomland community, which begins at this location along the mid-line. The presence of Carolina ash (Fraxinus caroliniana) and Black Gum (Nyssa sylvafica), as well as thick mats of sphagnum moss, are also significant vegetative indicators of a wetland community. Swollen basal areas of mature canopy trees suggested frequent flooding, although no standing water was observed. Handfuls of the organic soil surface revealed a rich mucky humus that smelled anoxic and appeared quiet deep (> 30 cm) before approaching a mineral horizon. This specific soil type appeared to be fairly limited in surface area (approximately 1 hectare or 3 acres), possibly due to changes in slope and terrain. Jurisdictional wetlands identified by the NWI as being located at the northwestern and southeastern boundaries of the site, were visible from Haws Run Road as low-land areas with thicker, greener lines of vegetation. These known wetlands are adjacent to the proposed borrow site, and appear to be outside of the proposed excavation area. 4.0 ENVIRONMENTAL IMPACTS Clearing the entire 55 acre site of trees and the associated vegetative cover would leave the site susceptible to localized erosion and fugitive dust impacts. Low hills, ridges and uplands would contribute to runoff, particularly at the southwest side of the site where the highest elevations are recorded. The potential of a positive identification and delineation of wetlands on-site (i.e. the hardwood bottomland forest) presents an unknown limitation regarding the potential yield of excavated materials expected to be recovered. In the event of this delineation, mitigation measures would be required. Jurisdictional wetlands adjacent to the borrow pit site would need to be protected from erosion and siltation. Sufficient vegetative barriers should be maintained between disturbed areas and wetland areas. No threatened or endangered plant species are known to inhabit the 55-acre site. However, road-side savanna species such as the venus flytrap , which is a candidate for state listing, and an unidentified yellow-eyed grass (potentially a State Special Concern species), were recorded along a portion of the North Road. Three roads pass east-west through the site creating openings in the forest canopy offering limited habitat to road- side savanna species such as these. The biological survey determined that the proposed borrow pit site is located outside of an area designated as red-cockaded woodpecker habitat and/or forage. No indication of inhabitation by the rare woodpecker was recorded during the survey. With the exception of a mature loblolly/longleaf pine stand located in the southeast portion of the parcel, Site #5 appears to lack sufficient suitable habitat to support the red-cockaded 14 woodpecker. Other communities consisting of potential foraging areas or cavity trees lacked the necessary land area or contiguous habitat that might attract the birds. Known red-cockaded woodpecker territory south of the site might be affected by the widening and/or upgrading of the Haws Run access road (Fig. 7). Before site preparations begin, consultations may be required with the U.S. Fish and Wildlife Service to evaluate possible impacts on these Federally endangered birds. 5.0 CONCLUSION The survey determined that the selected site is not inhabited by endangered or threatened species, or actively used by these species for forage. Use of Site #5 as a source for borrow material would have minimal impacts if proper mitigation measures are implemented to protect nearby sensitive resources such as jurisdictional wetlands and the endangered red-cockaded woodpecker. If the hardwood bottomland forest on the site should prove to be jurisdictional wetlands, additional mitigation measures may be required. t 'J s F-71 15 6.0 REFERENCES Avolis Engineering, P.A., 1992, Preliminary Report Borrow Pit Site Investigation for Greater Sandy Run Area, Engineering Study 92-93, Prepared for MCB Camp Lejeune.

(Ogden) has performed an archaeological investigation for a proposed borrow pit site located on the United States Marine Corps, Camp Lejeune training facility as a subcontract to The Environmental Company (TEC). The proposed action involves the utilization of a 55-acre site located off the Verona Loop Road (Figures 2-1 and 2-1). The site investigation was conducted by Ogden personnel from 07 June 1993 to 10 June 1993. The purpose of the investigation was to make a preliminary evaluation of potential archaeological resources located within the proposed borrow pit sites and the potential impacts which might result from utilization of these areas. Conclusions reached in this investigation are based on a visual inspection and limited subsurface testing. Appendix I contains captioned photographs of the sites. 1.2 SCOPE OF WORK The objective of this subcontract is to identify the presence and potential significance of any archaeological resources within boundaries of the proposed site. The methodology specified by TEC is outlined in the following tasks. TEC provided the contractor with the following background literature to be reviewed prior to the field visit. • Soil Survey for Camp Lejeune, Onslow County, North Carolina • Land Use Plan 1991 Update for Onslow County, North Carolina • Borrow Pit Site Investigations for Greater Sandy Run Area t • Camp Lejuene Complex Master Plan and Capital Improvements Plan Update, Engineering Study 92-33 • Phase IB Cultural Resource Investigations Greater Sandy Run Acquisition Area, Camp Lejeune Marine Corps Base To ensure that all available archaeological data concerning the proposed site was reviewed, Ogden coordinated the work with Mr. Mark Mathis of the North Carolina State Historic Preservation Office. The archaeological field surveys included surface examinations where ground visibility is adequate and subsurface testing as appropriate. It was anticipated that limited shovel testing would be required. TEC provided an environmental specialist to assist the contractor during the field survey; however, survey design was the responsibility of the contractor. 13 REPORT ORGANIZATION Section 2.0 contains the project background, site description, and cultural overview, project description and methodology. Section 3.0 contains the findings for the survey of the proposed borrow pit area. Ogden's conclusions and recommendations are summarized in Section 4.0. tiaeM > 2 1 2.0 PROPOSED BORROW PIT I 2.1 SITE LOCATION The proposed site is located on Hawsrun Road, approximately 800 meters north of the southern portion of the Verona Loop Road on the Camp Lejeune Marine Corps training base. 1 2.2 SITE DESCRIPTION The proposed site is approximately 55 acres in areal extent. Topographically, the site is composed of a relatively flat-lying, well drained terrain characterized by the presence of microlandforms. These microlandforms consist of low hills, ridges, and uplands 5 to 15 feet higher in elevation than surrounding areas. Elevations vary from 50 to 70 feet above mean sea level (MSL) over the site. The highest elevations are on the southwest side of the proposed borrow pit site. Vegetation on the site consists of a variety of forest cover ranging from pine upland to hardwood lowland. A small portion of the site was cleared as a result of logging activity. One wildlife food plot, known as the L-shaped food plot, was located in the southwest portion of the site and occupied approximately three acres. This area had been cleared I and planted in grasses. Some soil exposure is present in this area. 23 CULTURAL OVERVIEW The following overview is partially derived from information found in the Cultural Resources Research Proposal for the Greater Sandy Run Acquisition Area Camp Lejuene Marine Corps Base prepared by Louis Berger & Associates, Inc., July 1992.

LOCATION OF CAMP LEJUENE 4 The coastal plain of southern North Carolina shares a common prehistoric and early historic sequence with the greater southeastern United States. The prehistoric sequence is divided into three major periods: the Paleoindian period from 12,000 to 8,000 B.C.; the Archaic period from 8,000 to 1,000 B.C.; and the Woodland Period from 1000 B.C. to approximately 1650 A.D. The Paleoindian period has been characterized by the presence of small nomadic groups, relying on hunting of caribou and other animals as well as foraging and fishing. Cultural material from this period consists mainly of stone projectile points. In general, Paleoindian populations appear to have been small and campsites were temporary. Apparently, less than two dozen Paleoindian points have been reported from'the North Carolina Coastal Plain. The Archaic period is subdivided into early (8,000-5,000 B.C.), middle (5,000-3,000 B.C.), and late (3,000-1,000 B.C.) periods. Early Archaic subsistence patterns are characterized by hunting and gathering within well defined areas and on a seasonal basis. The Middle Archaic is differentiated by the incidence of dart points, atalatl weights, and an expanded assemblage of stone tools. The late Archaic has been characterized as a period of increased sedentism and the first use of steatite vessels. The late Archaic is regarded as transitional from a gathering economy to one of early agriculture. The Early Woodland period (1,000-300 B.C.) is marked by the first widespread use of pottery and the first evidence of true agriculturalism. The primary diagnostic ceramics are the sand-tempered New River pottery. The Middle Woodland period (300 B.C.- A.D. 800) is characterized by the expanded reliance on agriculture, indicated by presence of sites in more fertile soils and more advanced ceramic technology. The appearance of large triangular points indicate the introduction of the bow and arrow in the later phases of the Middle Woodland period. Sites with Middle Woodland components are more common than sites of any other M Bckx-) 5 period in Onslow County and Camp Lejeune. Ceramics indicative of Middle Woodland are clay-tempered Cartaret, Hanover, and coarse sand-tempered Cape Fear or Mount Pleasant pottery. The Late Woodland period (A.D. 800-1650) is characterized by larger consolidated communities with increased reliance on estaurine resources. " At Camp Lejeune most of the late woodland sites are shell middens or sites with significant amounts of shell debris" (Berger, 12). Diagnostic ceramics are gravel-tempered Onslow or Cashie pottery. The historical period begins in 1705 with the first settlements in the area at Towne Point on the New River. Following the Tuscarora War of 1715, the. area was open for settlement. The local economy appears to have been primarily agricultural in nature. "Substantial acres were planted in corn, with smaller investments in wheat flax, rice, indigo and hemp. In addition, cultivation of corn, sweet potatoes, and collards typically occurred at a subsistence level. However, the sandy soil and lack of efficient overland transportation inhibited the development of agricultural activities on the grand scale seen in other areas of the South" (Berger, 13). A rural agricultural economy appears to have predominated the area for many years. Almost nothing is known of the particular history of the proposed borrow area, however it seems likely that only small portions of the site have been agriculturally utilized due to poor soil. 85,000 acres, including the proposed site, were acquired by the U.S. Government in 1940-41 for construction of the permanent base at Camp Lejeune. Our investigation of the site revealed numerous surface disturbances by fire plows and marine training activities, including foxholes and disposal pits. 2.4 PROTECT DESCRIPTION AND METHODOLOGY A Cultural Resources Base Map prepared by Avolis Engineering, Inc. for the study area was furnished prior to commencement of the fieldwork. This map was based on ,,,.?? 6 correlations of known soil types with archaeological potential. The map indicated that small portions of the site are located in areas having a high potential (foreston type soils) for the presence of cultural/archaeological sites. Other portions of the site were said to have a low potential, while still other portions of the site were not evaluated. Onsite work began with an in-briefing on Monday, 07 June 1993, at the Camp Lejuene tati windshield t f th d b i f ll Thi ffi ff i y an or en on - our o e owe s was o ce. a rs o Environmental A site. Field work began on Monday afternoon with a pedestrian survey of the site d Th i i l d d e pe estr an survey nc u e including an east-west transect through the site. investigation and surface collection on roadways and areas of exposed surface. During the initial site walkover performed on 07 June 1992, exposed surface areas on the site and adjoining property to the southwest were examined for the presence of cultural material. This was followed by shovel testing areas of indicated high potential confirmed by the pedestrian survey and surface inspection. Vegetative cover and time constraints precluded the use of surveyed transects. However, a grid encompassing the site was laid out using a Brunton compass and tapes. This grid was along five parallel north-south transects approximately 220 meters apart extending' from the main road to the northern boundary of the site (Figure 2-2). Additionally, one east-west transect (A, etc.) was extended starting at an established orienteering station (ammunition box 62) located on the main road and known as point A. Archaeological transects were projected to the east from the roadway along transect A and at 50 or 100 meter intervals so as to cross the areas, of highest archaeological potential in an easterly direction. An archaeological transect was projected northward from point E. In addition, archaeological transects were projected from arbitrary points staked R and S located on microlandforms which appeared to have some archaeological potential. Shovel tests were performed at 20 meter intervals along these transects and continued past areas of potential. Shovel testing was conducted to an average depth of 60 centimeters. Soil screenirig utilizing 1/4-inch mesh hand screens was performed on all excavated material. ?,asck3.? 7 1 11 A total of 48 shovel tests were excavated over the site during the survey. No cultural material was obtained. Surface collections yielded some historic cultural material primarily along the road and on the portion of the site which had been logged. This material consisted of glass and china fragments. Additional fragments of china and glass were found on adjoining land to the southeast of the site. In addition to this material, a number of bi-valve shells were recovered from the same areas. Laboratory analysis of the material collected revealed possible dates for some of the china sherds. The pearlware fragments collected in the roadway could have been produced from the late 18th century to the mid 19th century, as other material recovered and submitted for analysis appears to date from the present century. A visual examination of the two species of bivalve mollusk shells was inconclusive (see Appendix II). ta.Ba) 8 ?I ¦ ?I ?I s e C FIGURE 2-2. SITE PLAN 9 3.0 SUMMARY OF FINDINGS The findings of this investigation are as follows: • No identifiable prehistoric cultural materials of archaeological interest were visually observed in surface examination or recovered in subsurface investigation activities on the subject site. • No identifiable historic cultural materials of archaeological interest were recovered in subsurface investigation activities on the subject site. • Small amounts of historic cultural materials were found during surface collection activities on the site and adjoining lands. • No physical evidence of historic occupation (i.e., foundations, chimneys, cellars) were visually evident on the site. • Laboratory analysis and examination of cultural material submitted from' the proposed site and surrounding areas may indicate the presence of historic era archaeological sites in the vicinity of the project area (Appendix II). MWOC-) 10 11 1 4.0 CONCLUSIONS AND RECOMMENDATIONS 4.1 CONCLUSIONS Small amounts of historic ceramic ware and glass found in surface collections on the road indicate the potential presence of a house site on or near the proposed borrow pit area at some time in the past. No cultural material was obtained from subsurface testing on the site. No physical evidence of occupation (i.e., foundations, chimneys, cellars) was visually evident on the site itself. Furthermore, areas of the site in proximity to the surface collections were extensively disturbed by fire control and Marine training activities. No diagnostic prehistoric material was recovered on the site in surface collections or subsurface testing. Some shell fragments were collected on the surface of the logged area near the Ir shaped food plot. Laboratory analysis of this material was not conclusive. Many shell fragments as well as historic glass and china fragments were collected in the area to the southeast of the proposed borrow pit site. As this area was outside the proposed borrow pit area, only cursory investigations were performed. There appears to be some archaeological potential on adjacent land to the southeast of the site. Based on surface examination, subsurface shovel testing, analytical data, and collected historical material, there appears to be a very low potential for the presence of significant archaeological resources on the proposed borrow pit site. 4.2 RECOMMENDATIONS Based on the conclusions of this investigation, there are no further recommendations for archaeological investigations on the proposed borrow pit site at this time. 11 t APPENDIX I PHOTOGRAPHS OF PROPERTY Taken On 07-10 June 1993 r 11 Photograph No. 1.

I have enclosed an inventory of those materials. We have not performed a formal malacological analysis of the shellfish remains, insofar as such would be of little relevance in..asse.ssing, the, importance of these loci within the context of the National Historic Preservation Act and the guideldnes-establis-hed--thereunder. The remainder of the artifacts reflect depositions during both the 19th and 20th centuries. The amber bottle glass recovered at FS# 3, and the clear glass vessel sherd from FS# 1, are probably from the present century. The pearlware vessel sherds could date to the late 18th century, but continued to be manufactured into the late 19th century. The Bristol glazed sherd likely post-dates circa 1880. All of the artifacts suggest a domestic use of the site area. We thank-you for the opportunity to be of service to you, and have returned the materials (labeled FS# 1 through FS# 7) herewith, together with our statement for services rendered.

Horsch, 1510 Gilbert Street, Norfolk Virginia, 23511-2699, has applied for a Department of the Army (DA) permit TO PLACE FILL MATERIAL IN 17.25 ACRES OF WETLANDS ADJACENT TO GREATER SANDY RUN, WEST OF US 17, NEAR VERONA, ONSLOW COUNTY, North Carolina. The following description of the work is taken from data provided by the applicant and from observations made during a site visit by a representative of the Corps of Engineers. Plans submitted with the application show that the proposed work is to occur within the area designated as Range P-949 and is to be a multi-purpose training range for use by the M1/A1 tank, and infantry and aerial assault troops. Construction necessary for the completion of this range will include: a firing area for tanks and infantry; access roads; parking areas; a dining area; a concurrent training station which would accomodate other troops training at the range; a control tower; utility corridors and associated facilities for the range's electrical, water and communications systems; a utility building which will serve as an aid station and command post as well as a facility for the storage and maintenance of equipment associated with the range; a storage area for ammunition; classrooms; instructional bleachers; and loading ramps. The proposed firing range involves the construction of a north and a south dual-track tank trail with a single return track. These trails traverse the range in a roughly east and west direction. There are "spurs" off the trails at varying points and in various alignments. The tanks will travel onto these spurs and will fire at multiple target types which are part of a fully equipped Remote Engagement Targeting System. Only ground to ground fire will occur at this range and only plastic non-explosive projectiles (each weighing about 25 pounds) will be fired. Each track (two per trail) is to be approximately 30 feet wide with drainage swales on either side. The targets will have a bunker constructed around them to protect them from accidental damage. The range will also have access and service roads, which will be approximately 12 feet wide with drainage swales located on either side. M -2- Various constraints restrict the functional training portion of the range to a 1,150 acre area. Various designs of the range were reviewed, and wetland impacts were reduced to 17.25 acres. The construction of the tank trails and service roads will result in most of the wetland impacts. Construction of the targets and their bunkers will result in impacts to approximately 0.25 acre of wetlands. The construction of the remaining facilities and structures on the range may result in minor wetland impacts. Based on plans provided by the applicant, it is assumed that, upon completion of the construction associated with these facilities and structures, a majority of the work will be confined to high ground or will result in negligible wetland impacts. Impacts associated with the plastic projectiles landing in wetlands are anticipated to be minimal. Because of the size of the range site, the type of wetlands to be impacted by the project are varied. Impacted areas are primarily scrub/shrub pocosin, with smaller inclusions of forested and emergent wetlands. .ome areas have been logged and/or burned at various times in the past. Significant areas have had their hydrological regimes altered by ditches during conversion to loblolly pine plantations. The applicant has redesigned the range in order to avoid wetlands to the maximum extent possible. Various design criteria, as well as the presence of historical resources, dictated the final layout. Where wetlands cannot be avoided, the range has been designed to minimize these impacts. These impacts, totalling 17.25 acres of wetlands, will be mitigated. The mitigation plan is conceptual and under review at this time. Most of the mitigation work will involve either restoration of loblolly pine plantations to fully functioning wetlands or enhancement of hydrologically impaired wetlands. The purpose of the work is to construct a multi-purpose training range for use by both infantry and armored troops. Plans showing the work are included with this public notice. The applicant has determined that the proposed work is consistent with the North Carolina Coastal Zone Management Plan and has submitted this determination to the North Carolina Division of Coastal Management (NCDCM) for their review and concurrence. This proposal shall be reviewed for the applicability of other actions by North Carolina agencies such as: a. The issuance of a Water Quality Certification under Section 401 of the Clean Water Act by the North Carolina Division of Environmental Management (NCDEM). b. The issuance of a permit to dredge and/or fill under North Carolina General Statute 113-229 by the North Carolina Division of Coastal Management (NCDCM). C. The issuance of a permit under the North Carolina Coastal Area Management Act (CAMA) by the North Carolina Division of Coastal Management (NCDCM) or their delegates. -3- d. The issuance of an easement to fill or otherwise occupy State-owned submerged land under North Carolina General Statute 143-341(4), 146-6, 146-11, and 146-12 by the North Carolina Department of Administration (NCDA) and the North Carolina Council of State. e. The approval of an Erosion and Sedimentation Control Plan by the Land Quality Section, North Carolina Division of Land Resources (NCDLR), pursuant to the State Sedimentation Pollution Control Act of 1973 (NC G.S. 113 A-50- 66). The requested Department of the Army (DA) permit will be denied if any required State or local authorization and/or certification is denied. No DA permit will be issued until a State coordinated viewpoint is received and reviewed by this agency. Recipients of this notice are encouraged to furnish comments on factors of concern represented by the above agencies directly to the respective agency, with a copy furnished to the Corps of Engineers. This application is being considered pursuant to Section 404 of the Clean Water Act (33 U.S.C. 1344). Any person may request, in writing within the comment period specified in the notice, that a public hearing be held to consider this application. Requests for public hearing shall state, with particularity, the reasons for holding a public hearing. The District Engineer has consulted the latest published version of the National Register of Historic Places for the presence or absence of registered properties, or properties listed as being eligible for inclusion therein, and this site is not registered property or property listed as being eligible for inclusion in the Register. Consultation of the National Register constitutes the extent of cultural resource investigations by the District Engineer, and he is otherwise unaware of the presence of such resources. Presently, unknown archeological, scientific, prehistorical, or historical data may be lost or destroyed by work under the requested permit. The District Engineer, based on available information, is not aware that the proposed activity will affect species, or their critical habitat, designated as endangered or threatened pursuant to the Endangered Species Act of 1973. The decision whether to issue a permit will be based on an evaluation of the probable impacts, including cumulative impacts, of the proposed activity and its intended use on the public interest. Evaluation of the probable impacts which the proposed activity may have on the public interest requires a careful weighing of all those factors which become relevant in each particular case. The benefits which reasonably may be expected to accrue from the proposal must be balanced against its reasonably foreseeable detriments. The decision whether to authorize a proposal, and if so the conditions under which it will be allowed to occur, are therefore determined by the outcome of the general balancing process. That decision should reflect the national concern -4- for both protection and utilization of important resources. All factors which may be relevant to the proposal must be considered including the cumulative effects thereof. Among those are conservation, economics, aesthetics, general environmental concerns, wetlands, cultural values, fish and wildlife values, flood hazards and flood plain values (in accordance with Executive Order 11988), land use, navigation, shore erosion and accretion, recreation, water supply and conservation, water quality, energy needs, safety, food and fiber production, mineral needs, considerations of property ownership, and, in general, the needs and welfare of the people. For activities involving the placement of dredged or fill materials in waters of the United States, a permit will be denied if the discharge that would be authorized by such permit would not comply with the Environmental Protection Agencies' 404(b)(1) guidelines. Subject to the preceding sentence and any other applicable guidelines or criteria, a permit will be granted unless the District Engineer determines that it would be contrary to the public interest. The Corps of Engineers is soliciting comments from the public; Federal, State and local agencies and officials; Indian Tribes and other interested parties in order to consider and evaluate the impacts of this proposed activity. Any comments received will be considered by the Corps of Engineers to determine whether to issue, modify, condition or deny a permit for this proposal. To make this decision, comments are used to assess impacts on endangered species, historic properties, water quality, general environmental effects and the other public interest factors listed above. Comments are used in the preparation of an Environmental Assessment (EA) and/or an Environmental Impact Statement (EIS) pursuant to the National Environmental Policy Act (NEPA). Comments are also used to determine the need for a public hearing and to determine the overall public interest of the proposed activity. Generally, the decision whether to issue this Department of the Army (DA) permit will not be made until the North Carolina Division of Environmental Management (NCDEM) issues, denies, or waives State certification required by Section 401 of the Clean Water Act. The NCDEM considers whether or not the proposed activity will comply with Sections 301, 302, 306, and 307 of the Clean Water Act. The application and this public notice for the Department of the Army (DA) permit serves as application to the NCDEM for certification. Additional information regarding the Clean Water Act certification may be reviewed at the offices of the Environmental Operations Section, North Carolina Division of Environmental Management (NCDEM), Salisbury Street, Archdale Building, Raleigh, North Carolina. Copies of such materials will be furnished to any person requesting copies upon payment of reproduction costs. The North Carolina Division of Environmental Management (NCDEM) plans to take final action in the issuance of the Clean Water Act certification on or after August 12, 1994. -5- All persons desiring to make comments regarding the application for Clean Water Act certification should do so in writing delivered to the North Carolina Division of Environmental Management (NCDEM), Post Office Box 27687, Raleigh, North Carolina 27611-7687, on or before August 8, 1994, Attention: Mr. John Dorney.

To this end, LANTDIV has provided contracted technical and professional support for wetland delineation on Greater Sandy Run Area (GSRA) adjacent to Marine Corps Base Camp Lejeune (MCBCL) located in Onslow County, North Carolina (Figure 1-1). The GSRA is approximately 41,000 acres and was acquired in 1992 to provide sufficient land training areas and available firing ranges at MCBCL. The P-949 Multi-Purpose Training Range (MPTR), designated SR-7, is the first proposed range at GSRA (Figure 1-2). The range is designed to accommodate the Ml/A1 tank, and to train infantry and aerial assault troops, both singly and in coordinated exercises. P-949 MPTR consists of a dual track tank trail, with a single return track and a Remote Engagement Target System with multiple target types. Other facilities at the MPTR will include classrooms, instructional bleachers, ammunitions storage, loading ramps, and sanitation facilities. The Marine Corps will fire only plastic non-explosive projectiles in the MPTR. P-949 MPTR is located in the northeastern corner of GSRA, with its safety fan extending 9,000 meters (m) toward the western boundary. This range is the second largest to be developed on GSRA. Ten ranges and associated support facilities are proposed for development (Figure 1-2). 1.2 Project Objectives The primary objective of this project is to provide a complete and accurate delineation of the jurisdictional wetlands on P-949 MPTR. An accurate map of wetlands within the P-949 MPTR will be used by LANTDIV and MCBCL to determine the placement of the proposed MPTR. 1-2 Source: EDAW, Inc., 1993.

' 1-3 1.3 Report Organization ' This report is subdivided into seven sections, including this introduction. A description of the GSRA, P-949 MPTR, and natural resources is given in Section 2.0. Federal and State wetland regulations are presented in Section 3.0. The jurisdictional wetland delineations, including procedures, maps, and results are presented in Section 4.0. Section 5.0 presents alternatives for the P-949 MPTR. The literature cited ' in this document are listed in Section 6.0. 1-4 2.0 DESCRIPTION OF MCB CAMP LEJEUNE/ GREATER SANDY RUN AREA 1 2.0 DESCRIPTION OF GREATER SANDY RUN AREA (GSRA) 1 2.1 Physiography 1 The GSRA lies on the Lower Coastal Plain. Most of the area is composed of wide undisseeted instream areas. There is very little topographic relief; the highest elevation for the area is only 67 feet mean sea ' level (MSL). The area is dominated and influenced by two expansive pocosin wetlands that have been altered by a series of canals and ditches. 2.2 Land Use Most of GSRA was acquired from a paper company which managed the area for timber production. Privately-owned parcels, including residences, small businesses, and small farms comprised the remaining acreage. Various wood and paper companies have controlled most of GSRA for the past 45 years. Most of the saleable timber was harvested prior to acquisition by MCBCL. Currently, the area is dominated by immature, undeveloped, monoculture pine plantations of various ages. Historically, agricultural uses within GSRA have been limited due to an overall lack of prime farm land in the area. Residential and commercial uses have existed on small peripheral portions of the area since the 1950's. The communities of Verona, Dixon, Holly Ridge, Folkstone, and Padgett border the GSRA. Military land use has been limited to helicopter training on the former World War II Army training facility at Camp Davis. 2.3 Climate The climate in the area consists of hot and humid summers with cool winters, and a relatively short cold period. The average summer temperature is 76° F, and the average winter temperature is 45° F. The average daily maximum temperature is 87° F with an average winter daily minimum temperature of 32° F. The highest temperature recorded was 103 ° F in June 1954. The lowest temperature recorded was 2' F in February 1965. Freezing temperatures occur between mid-November and the end of March, mostly in late December and January. The last freezing temperature (< 32°F) in spring for five years in 10 years is later than April 22; the first freezing temperature in fall for the same probability is October 24. The growing season, with daily minimum temperatures higher than 32°F, for five years in 10 years is 184 days (USDA 1992). 2-1 i The average yearly rainfall is 34 inches. Nearly 60 percent of the average precipitation falls in April through September. Thunderstorms occur approximately 45 days each year. Snowfall in the area ' averages three inches a year. The average relative humidity in mid-afternoon is 55 percent. Hurricanes have historically crossed the area every few years. Prevailing winds are generally from the south or ' southwest in spring and summer and from the north and northwest in the fall and winter. Wind speeds average nine miles per hour during the day. 2.4 Water Resources Alluvial alustrian forested p wetlands (pocosins) play an important role in the GSRA (Figure 2-1). These ' pocosins control flooding; improve water quality; and provide quality fish and wildlife habitat. The GSRA pocosin and its associated creeks and drainages are the dominant hydrological features affecting ' the P-949 MPTR. Five major drainage outfalls are located throughout the GSRA: Sandy Run Swamp Creek, Juniper Swamp Creek, Shelter Swamp Creek, Haws Run, and Hicks Run. Input of water into the system is primarily by precipitation. Discharge from the pocosin system comes primarily from surface run-off and evapotranspiration as opposed to groundwater seepage. Flooding is not a major ' problem within the GSRA. The pocosins act like giant sponges during storm events, as their thick peat layers soak up rainwater, and release it slowly over time. Surface run-off is slow because of the level ' topography in the area. ' Artificial drainage systems have been extensively created apparently by the various timber companies that have owned the area prior to military acquisition to assist in siviculture practices. Drainage ditches assist in lowering the water table and expedite surface run-off. These practices allow equipment access to areas ' that were otherwise inaccessible. Pine plantations that were established in the GSRA have benetitted from these practices. It is estimated in the Draft and Final EIS for the proposed expansion and realignment ' of the MCB-Camp Lejeune, that approximately four percent (1.6 km' or 398 acres) of the GSRA's pocosin community has been previously drained and ditched (USMC 1989, 1990). The natural drainage pattern for the GSRA is from east to west. There are three primary drainageways that originate on the GSRA. P-949 MPTR is not affected by these major drainageways. 2-2 u Source: EDAW, Inc., 1993. GSRA Master Development Plan Figure 2-1. Wetland drainage pattern on Greater Sandy Run Area, Marine Corps Base Camp Lejeune. 2-3 ' 2.5 Soils The majority of soil types identified at GSRA consist of tine sandy loamy, with the remainder classified as mucks, mucky loams, sandy loams, and fine sands. The majority of these soils are hydric in nature, and exhibit high water tables, high organic content, and small particle size. The soil types and their generalized characteristics are described below. In general, the soils at P-949 MPTR have low potential for water and wind erosion. The permeability of the soils ranges from 0.06 to 20 inches per hour. The water table is near the surface, especially during the growing season. The shrink-swell classification for all soil groups is low. The specific soil properties vary slightly depending on whether the soil is in depressional, flooded, or upland land forms and by the properties of the underlaying substratum. Selected properties related to soil erosion and runoff factors of the soils found at P-949 MPTR are listed in Table 2-1. 2.6 Natural Communities The study area for determining wetland boundaries and natural communities within siting constraints of P-949 MPTR was 1500 m x 3100 m (1150 acres). Natural communities were identified and classified into two broad categories; upland and wetland communities. Upland community profile descriptions were adopted and modified from the North Carolina Natural Heritage Program classification scheme (Schafale and Weakley 1990). Wetland communities were subdivided and classified according to the Cowardin et al. land classification system, which was developed by the U.S. Fish and Wildlife Service (Cowardin et al. 1979). The primary objective of the Cowardin et al. system is to impose boundaries on natural ecosystems for the purpose of inventory, evaluation, and management. Faunal descriptions were supplemented from NCASI (1992). Fifteen wetland community types were identified during the field surveys (Figure 2-2). 2.6.1 Upland Upland areas cover 708 acres (61 percent) including pine woodlands, mixed pine, and mixed pine hardwood forest. Distribution and composition of these communities throughout the study area reflect the effects of topographic positioning, hydrologic influences, and past land use practices. 2-4 U U ?

Y N ( 1 N Pine woodlands Areas of pine woodlands, characterized by a dominant loblolly pine (Pinus taeda) canopy, occur in a ' patchwork arrangement throughout the study area. Many of these areas were planted for pulpwood production; however, active management no longer exists. In young stands, canopy closure is complete ' and virtually impenetrable, intertwined with greenbriar (Smilax spp.), honeysuckle (Lonicera japonica), and yellow jessamine (Gelsemium sempervirens). However, on older tracts, a variety of hardwoods may ' appear in the understory including red maple (Acer rubrum) and sweet gum (Liquidambar styraciflua). ' Pine woodlands occupy nearly level, poorly drained to somewhat poorly drained areas scattered throughout the study area. A large majority of these areas have been ditched to facilitate drainage. ' These drained areas were then bedded to allow for the planting of pine seedlings. This community type is essentially a fire maintained community. Without the benefit of periodic fires to remove accumulated ' ground litter and newly established hardwoods, the woodlands association may eventually succeed to a mixed pine hardwood forest. Natural functions of this vegetation community include timber production, ' mineral recycling, and some water storage and purification. Pine woodlands also provide physical/chemical buffers to wetland areas on the property. r Mixed pine This community type is dominated by loblolly pine with scattered individuals of longleaf pine (Pinus palustris) and pond pine (Pinus serotina). These stands are on the upland-wetland interface and grow on the hydric Leon soil series, a highly permeable sand not generally utilized in crop production. They are somewhat elevated, and do not appear to have a sustainable wetland hydrology. Common associates in this type are sweetgum, red maple, and red bay (Persea borobonia). The shrub and herb layers are sparse to moderate in density. The mixed pine community type is also dependant upon fire for its maintenance. Without fire to remove encroaching hardwood species, this community will eventually succeed to a mixed pine hardwood forest along drier, well-drained locales or a pine-titi (Cyrilla) transitional forest along wetter, poorly-drained areas. Mixed pine communities provide the same functions as those previously mentioned for pine ' woodlands. 1 1 2-7 Mixed pine hardwood A variant of pine woodlands, this community is reflective of the age of the stand and degree of maintenance. The primary identification factor is the mix of pines and hardwoods in the canopy. Loblolly pines share canopy dominance with sweet gum, red maple, loblolly bay (Cordonia lasianthus), and laurel oak (Quercus laurifolia). Mixed pine hardwood communities occur on relatively flat, moderately to poorly drained terrain. This community is located in the transition zone between the upland pure pine communities and the wet hardwood bottomlands, where some seasonal flooding occurs. Unlike most communities, the mixed pine hardwoods do not have a dominant stress factor. There is some competition between plants for use of water, sunlight, and available nutrients. Once established, they can withstand disturbance due to the complex and diverse vegetation and the excellent plant growth conditions. The community is fire resistant but fire may occur during drought conditions. 2.6.2 Wetland Five major wetland systems are defined in the Cowardin classification system: marine, estuarine, riverine, lacustrine, and palustrine. Palustrine wetlands were the only type found in the study area and cover 443 acres (39 percent). Palustrine wetlands include all nontidal wetlands dominated by trees, shrubs, persistent emergents, emergent mosses, or lichens. This system groups the vegetated wetlands traditionally called marshes, swamps, bogs, fens, prairies, and ponds. Four classes of palustrine wetlands occur in the study area: forested, scrub-shrub, emergent, and a combination of forested and scrub-shrub. A detailed description of the forested scrub-shrub and emergent wetland classes follow. A separate discussion of the forested/scrub-shrub class is not provided since each are discussed separately. 2.6.2.1 Forested ' Palustrine forested wetlands occupy six different categories at P-949 MPTR. These include: 1) PF04B--Needle-leaved evergreen forests growing on saturated sites; ' 2) PFOIC--Broad-leaved deciduous forests growing on seasonally flooded sites; 3) PFO1 B--Broad-leaved deciduous forests growing on saturated sites; ' 4) PFO1 /2C--Broad-leaved deciduous/needle-leaved deciduous forests growing on seasonally flooded sites; 2-8 5) PFOI/3B--Broad-leaved deciduous/broad-leaved evergreen forests growing on saturated sites; and 6) PFO1/413--Broad-leaved deciduous/needle-leaved evergreen forests growing on saturated sites. The source of flooding on these sites is either from established drainages like canals, ditches, or streams, or subsurface sources. Such flooding, if of sufficient duration, satisfies the wetland hydrology criteria for jurisdictional wetland determinations. Dominant canopy species typically have a wetland indicator status of facultative (FAC) to facultative wetland (FACW), as does the shrub and herb stratum. The soils are hydric and in most cases, highly organic. Soils reflect the anaerobic conditions produced by prolonged saturation. The character of the forested wetland cover types found in the study area relates directly to site conditions, the degree of saturation, and the successional stage. The forest canopy and upper crown classes are characterized by dominants and codominants of loblolly pine, red maple, pond pine, black gum (Ayssa sylvatica var. biflora), sweet bay (Magnolia virginica), and sweet gum. The shrub stratum consists of suppressed individuals of the above species and naturally smaller species like bitter gallberry (Ilex glabra), fetterbush, (Lyonia lucida), loblolly bay, bayberry (Myrica heterophylla), horse sugar (Symplocos tinctoria), sweet pepperbush (Clethra alnifolia), American holly (Ilex opaca), red bay, titi (Cyrilla racemiflora), and highbush blueberry (Vaccinium corymbosum). The herb layer commonly consists of bamboo (Smilax laurifolia), broom sedge (Andropogon spp.), cinnamon fern (Osmunda cinnamomea), and yellow jessamine. Typical animals inhabiting this community include white tailed deer (Odocoileus virginianus), opossum (Didelphis virginicus), cotton mouse (Peromyscus gossypinus), raccoon (Procyon lotor), short-tail shrew (Blarina brevicauda), red-eyed vireo (Vireo olivaceus), parula warbler (Parula americana), barred owl (Stria varia), red-shouldered hawk (Buteo lineatus), hairy woodpecker (Picoides villosus), eastern cottonmouth (Agkistrodon piscivorus), mud snake (Farancia abacura), rough green snake (Opheodrys aestivus), cricket frog (Acris gryllus), green treefrog (Hyla cinerea), and dwarf salamander (Eurycea quadridigitata). The maintenance of natural hydrological regimes is critical to the health of forested wetlands. Species composition will be affected if the hydroperiod is significantly altered. Some species that survive well with extended flooding require drydowns for reproduction. Some species look healthy, but do not grow when constantly inundated. Others may die under these conditions. Several species suffer stress and disease when the water table is lowered or the hydroperiod is shortened. Additionally, shorter 2-9 1 hydroperiods and lower water tables allow the survival of upland mesophytic species. Forested wetlands function in filtering and assimilating excessive nutrients and pollutants from upland runoff as well as from ambient water sources. They also store water during periods of heavy rainfall and provide wildlife habitat. 2.6.2.2 Scrub shrub Scrub shrub wetlands occupy four different categories at P-949 MPTR. These include: 1) PSS313--Broad-leaved evergreen species growing on saturated sites; 2) PSS4B--Needle-leaved evergreen species growing on saturates sites; 3) PSS4/113--Needle-leaved evergreen/broad-leaved deciduous species growing on saturated sites; and 4) PSS3/4B--Broad-leaved evergreen/needle-leaved evergreen species growing on saturated sites. A scrub shrub wetland is a transitional community in most cases; a successional stage characterized by aggressive soil-building processes and smaller or younger vegetation. It is often found associated with an emergent wetland or as a component of a larger forested wetland system. Left undisturbed, its woody components will increase, leading to a forested climax type. Water regimes involve saturated soil conditions; therefore, species composition closely follows this pattern of saturation. The typical structure and species composition of this community consists of a low canopy of loblolly bay, pond pine, loblolly pine, and sweet bay with a persistent shrub stratum. Where shrub competition is slight, the herb stratum flourishes. Common species of the shrub stratum are bitter gallberry, red bay, titi, fetterbush, highbush blueberry, wax myrtle (Myrica cerifera), red maple, sweet pepperbush, and winterberry (Ilex verticillata). Common herbs are bamboo, cinnamon fern, broomsedge, meadow-beauty (Rhexia mariana), and redroot (Lachnanthes caroliniana). Common faunal inhabitants include white- tailed deer, raccoon, marsh rabbit (Sylvilagus palustris), golden mouse (Peromyscus nuttalli), harvest mouse (Reithrodontomys humulis), common yellowthroat (Geothlypis trichas), Acadian flycatcher (Empidonax virescens), great crested flycatcher (Myiarchus crinitus), yellow-breasted chat (Icteria virens), broad-headed skink (Eumeces laticeps), eastern cottonmouth, southern toad (Bufo terrestris), and pine woods treefrog (Hyla femoralis). 2-10 fl Scrub shrub wetlands, like forested wetlands are also dependant upon water levels and an adequate water regime to insure their continued existence. Because of their successional stage they often evolve into a more mature forested system. Scrub shrub wetlands function as physical buffers to flood waters, chemical buffers to water and air pollution, and as wildlife habitat. 2.6.2.3 Emergent Emergent wetlands within GSRA are herbaceous wetlands found in wetland forest tracts which have been cleared by logging. These systems are generally limited in size and distribution. The only category of emergent wetlands found at P-949 MPTR was persistent species growing in saturated soil conditions (i.e. PEM1B). This system, like the scrub shrub community, is also in the early stages of transition. This is evident by the number of scrub shrub species which occur throughout the area. Without further disturbance, the emergent wetlands at P-949 MPTR will succeed to a scrub shrub community. Vegetation and wildlife includes those species particularly suited to flooded conditions during the growing season. Primary productivity is high in these systems and many species of wildlife are supported. Shrub layer vegetation, when present, is dominated by red bay, fetterbush, sweet bay, and bitter gallberry. The characteristic herbaceous vegetation includes bamboo, broomsedge, goldenrod (Solidago spp.), spagnum (spagnum spp.) and bracken fern. Typical animals include raccoon, marsh rabbit, green heron (Butorides striatus), great egret (Casmerodius albus), red-winged blackbird (Agelaius phoeniceus), little blue heron (Florida caerulea), eastern cottonmouth, eastern ribbon snake (Thamnophis sauritus), banded water snake (Nerodia fasciata), southern leopard frog (Rana utricularia), green frog (Rana clamitans), and lesser siren (Siren intermedia). Fire, an integral component of emergent wetland systems, maintains the open herbaceous community by restricting shrub invasion. The normal interval between tires is one to 10 years, with strictly herbaceous marshes burning every one to three years, and those with substantial shrub growth having gone three to 10 years without tire. Emergent wetlands function in the filtration and assimilation of excessive nutrients and pollutants, in water storage, and in wildlife habitat. 2-11 3.0 REGULATORY COMPLIANCE 3.0 REGULATORY COMPLIANCE 3.1 Federal Regulations The Federal Water Pollution Control Act of 1948 (PL 80-845) was the first comprehensive statement of Federal interest in clean water programs (WPCF 1987). The 1972 amendments to the Act (PL 92-500), also known as the Clean Water Act (CWA), made the Environmental Protection Agency (EPA) primarily responsible for directing and defining water pollution control programs across the country. The objectives of the CWA are to maintain and restore the condition of waters of the United States for fish, shellfish, wildlife, and recreation. Furthermore, the CWA recognizes and preserves states' primary responsibility to achieve these objectives. 3.1.1 U.S. Army Corps of Engineers Section 404 of the CWA authorizes the Secretary of the Army, acting through the Chief of Engineers, to issue permits for the discharge of dredged or fill material into waters of the United States, including wetlands (33 USC 1344). The selection and use of disposal sites must be in accordance with guidelines developed by the Administrator of EPA and the Secretary of the Army. Thus, the Administrator may deny, prohibit, restrict, or withdraw the use of a disposal site if discharge of materials into the area would result in unacceptable adverse effects on municipal water supplies, fish and wildlife resources, or recreational areas (40 CFR Part 230). Department of Army permits are issued under two basic formats, individual and general permits. Permits may be issued following review of individual applications for a specific project and to authorize a category of activities that are substantially similar in nature and cause only minimal individual and cumulative environmental impacts in specific geographical regions or nationwide. Individual permits may be authorized by Department of Army following a case by case evaluation of specific projects involving proposed discharges. General permits may be authorized to avoid unnecessary duplication of Federal, state, or local agency regulatory control. Regional and nationwide permits are types of general permits. Regional permits may be issued to cover individual activities that are substantially similar in nature. The individual activities falling within categories authorized by such regional permits may not require further authorization by the procedures specified in processing Department of Army permits. A nationwide permit may be issued which may authorize activities throughout the nation. General permits may not be valid for more than five years. 3-1 r General policies for evaluating permit applications have been established. The benefits which may reasonably be expected from a proposed activity must be balanced against its foreseeable detriments to the public interest. The unnecessary alteration or destruction of wetlands, which constitute a productive and valuable public resource, should be discouraged as contrary to public interest. The Army will give full consideration to the views of State and Federal agencies responsible for management of fish and wildlife resources in deciding the disposition of permit applications. Permit applications may be evaluated for compliance with applicable water quality standards and the authority of states to allocate water quantities shall not be superseded, abrogated, or otherwise impaired by issuance of a permit. Full evaluation of the general public interest regarding historic, cultural, scenic, and recreational resources is made to avoid significant adverse effects on the values or purposes of these classifications. A Department of Army permit does not convey property rights nor authorize any injury to property or invasion of other rights. Significant adverse impacts associated with the occupancy and modification of floodplains should be avoided, as well as the direct and indirect support of floodplain development whenever there is a practicable alternative. Consideration of mitigation will occur throughout the permit application review process to ensure that the proposed project is not contrary to the public interest. All other policy considerations are made to benefit public interest. The two basic components of Section 404 are "dredged or fill material" and "waters of the United States". Dredged material means material that is excavated or dredged from waters of the United States. Fill material means any material (including extensive placement of pilings) used for the primary purpose of replacing an aquatic area with dry land/material or of changing the bottom elevation of a waterbody. Discharge of fill material means the addition of fill material into wetlands and/or waters of the United States. Waters of the United States are broadly defined as territorial seas; tidal and non-tidal waters, including adjacent wetlands; and all other waters of the United States, including isolated wetlands and lakes, intermittent streams, prairie potholes, and other waters including tributaries to interstate waters or navigable waters of the United States, the degradation of which could affect interstate commerce. Special aquatic sites have been identified in 40 CFR Part 230 and included as waters of the United States. Prior converted cropland is specifically excluded from waters of the United States. Discharge of dredged material means the addition or redeposition of dredged or excavated material to a specific site that would have the effect of destroying or degrading any area of waters of the United States, and runoff or overflow from a contained land or water disposal area. Mechanized land clearing, ditching, 3-2 i channelization, or other excavation activities are specifically identified as means of discharge of dredged material. However, discharge of dredged material does not include discharge of pollutants, which is subject to Section 402 of the CWA, and activities that involve only the cutting or removing of vegetation above the ground where the activity neither substantially disturbs root systems nor redeposits excavated soil material. An activity is considered to destroy waters of the United States if it alters the area such that it would no longer be classified a water of the United States. An activity is considered to degrade waters of the United States if it has more than an inconsequential effect on the area by causing an identifiable individual or cumulative adverse effect on any aquatic function. Discharge of dredged or till material from the following activities is not prohibited by or otherwise subject to regulation under Section 404, except as provided at the end of this paragraph: (1) normal farming, silviculture, and ranching activities; (2) maintenance of dikes, dams, levees, groins, riprap, breakwaters, causeways, bridge abutments or approaches, and transportation structures; (3) construction or maintenance of farm or stock ponds or irrigation ditches or the maintenance (but not construction) of drainage ditches; (4) construction of temporary sedimentation basins on a construction site which does not include placement of fill material into waters of the United States; (5) any activity authorized under Section 208 of the CWA; and (6) construction or maintenance of farm roads, forest roads, or temporary roads for moving mining equipment in accordance with best management practices. The two exceptions to these scenarios which would trigger Section 404 unauthorized use are discharge of any toxic pollutant listed under Section 307 of the CWA, and the discharge of dredged or till material where the flow or circulation of waters of the United States may be impaired or reduced. 3.2 State Regulations Section 401 of the Clean Water Act (CWA) requires that the state issue or deny water quality certification for any federally permitted or licensed activity that may result in a discharge to the waters of the United States. This requirement includes Section 404 permits issued by the U.S. Army Corps of Engineers (COE) for dredge and till activities. 3-3 3.2.1 North Carolina Department of Environment, Health and Natural Resources The North Carolina Department of Environment, Health and Natural Resources; Division of Environmental Management (DEM) is responsible for administering the state's 401 Water Quality Certification program. The Division's statutory authority to enact regulations for implementation of the CWA is contained in NCGS 143-215.3(a)(1) and (c). Effective October 1, 1989, the North Carolina Environmental Management Commission (EMC) adopted Rule 15A NCAC 2B .0109. This rule is consistent with EPA guidance and COE regulations and states: "Projects that alter the reach and extent of a freshwater wetland will not be considered as removing existing uses of the wetland in violation of the Antidegradation Policy [pursuant to 15A NCAC 2B .0201 (b)] if the alteration protects all existing and designated uses of all waters of the State. In making this determination, the Director will be guided by 40 CFR part 230, Subparts A through F. " Wetlands in North Carolina have not yet been formally delimited or "classified" as have other waters in the state. Classification is a process by which the EMC, with the assistance of DEM, determines the "designated uses" of specific areas of waters and through the public rulemaking process establishes the proper classification, standards or management practices of those waters based on their designated uses. All significant and nonincidental existing uses of waters, including those of wetlands, are protected under a water quality rule known as the "antidegradation policy" (15A NCAC 2B .0201), even if the waters have not been formally classified or their uses designated. "Existing use" is defined as any use that is actually attained in the waters on or after November 28, 1975 [(15A NCAC 2B .0202(17)]. The state's antidegradation policy, required by EPA, states that beneficial existing uses of waters may not be removed. One or more of the following beneficial uses, and/or others not listed here, may exist in a given wetland: conveyance and storage of floodwaters; abatement of water pollution; augmentation of surface water flow during drought; groundwater recharge; shoreline stabilization; timber production; and habitat for fish, wildlife and plants including rare, threatened and endangered species. These and other significant, non-incidental existing uses of wetlands are protected under the antidegradation policy. The state may not grant a 401 Water Quality Certification for a 404 permit 34 ' application in a wetland if significant existing uses will be removed by the project unless no practicable alternative exists. Activities that result in the discharge of till material into the waters of the State (which include wetlands) ' require a Section 404 permit from the COE (Section 404, Clean Water Act) and a 401 Water Quality Certification from the DEM (Section 401, Clean Water Act). Certifications for use in North Carolina ' fall under two categories, general and individual. General certifications are issued for activities which have been determined to have minimal impact on waters of the State. Projects that the Division has ' determined are likely to have a significant adverse effect upon water quality or projects that result in the loss of existing uses of the wetland or downstream waters must obtain an individual Water Quality ' Certification. 3-5 L 4.0 WETLAND DELINEATION 4.0 WETLAND DELINEATION 4.1 Background In the past 200 years, North Carolina has lost approximately 5.4 million acres of wetlands (an historical loss of almost 49 percent). Estimates developed by the USFWS reported that North Carolina still contained about 5.7 million acres of wetlands (about 17 percent of the State's land area) circa 1980's (Dahl 1990). North Carolina has the fifth largest amount of remaining wetlands within the United States. Approximately 95 percent of the State's wetlands occur within the Coastal Plain Region. Wetland drainage, filling, and water manipulation for agriculture and silviculture operations have resulted in the loss of large amounts of wetland habitat. According to the North Carolina Division of Parks and Recreation, a number of wetland types (i.e., Carolina bays, bogs, pocosins, and bottomland hardwoods) are still in need of protection due to imminent conversion pressures. Natural wetlands provide benefits to fish and wildlife, environmental quality, and socioeconomic values (Tiner 1984). The extent and variety of wetlands on P-949 MPTR contribute to the wetland functions and values of North Carolina's freshwater wetlands. The U.S. Army Corps of Engineers (Wilmington District) have jurisdictional authority over the wetlands on P-949. The COE-Wilmington was contacted to request a review of P-949 MPTR development concerning compliance with Federal wetland regulations. The COE stated that work on the area must be done in compliance with applicable Federal wetlands legislation, and that compensatory mitigation could be required for all wetland impacts. 4.2 Procedures Remote sensing of aerial photography, soil survey, and topography; Geographic Information System (GIS); and Global Positioning System (GPS) technologies were used to delineate preliminary wetland boundaries on 1150 acres. Federal wetland regulators were consulted to determine procedural and permitting requirements of jurisdictional wetlands. The layout of P-949 MPTR was digitized into the GIS using surveyed control points. Stereoscopic photo-interpretation of the P-949 MPTR area provided preliminary wetland boundaries and cover types for field survey data collection and ground-truthing. Wetland boundaries, cover types, and range design were digitized into the GIS for analysis of wetland 4-1 I ' areas and wetland impacts. The digital layers were georectified according to known (surveyed) control points provided by MCB-Camp Lejeune to create an accurate map of wetlands within the range area. Blueline copies of aerial photograph enlargements (1" = 100 m) were used for field delineation of ' jurisdictional wetland boundaries. Photo interpretation of cover types and preliminary wetland boundaries were transferred to the blueline copies to serve as a guide for field data collection and ground-truthing. ' Parallel transect lines spaced 100 m apart were transferred to blueline maps and provided to professional biologists who walked the length of each transect. A routine delineation based on the 1987 Corps of Engineers Wetland Delineation Manual was used to locate jurisdictional wetland boundaries. A delineation form was completed at each cover type/wetland/non-wetland boundary and sufficient data were recorded to support the jurisdictional determination (Figure 4-1). The wetland boundary between transects was located and confirmed by biologists on adjacent transects. The delineation forms corresponded to specifically numbered transects and sampling locations identified on the blueline maps. All adjustments to the cover type/wetland/non-wetland boundaries made during the field surveys were digitized into the GIS for calculation of the extent of jurisdictional wetlands and potential wetland impacts from proposed development of P-949 MPTR. Delineating an area as wetland required at least one positive indicator each of hydrophytic vegetation, wetland hydrology, and hydric soils. If an area failed to contain positive indicators of any of the three parameters, then the area was not delineated as wetland. Plant community designation and wetland or non-wetland designation were determined on-site based on sample data. As mentioned previously, plant communities (cover types) were designated according to the Cowardin classification system. At each cover type/wetland/non-wetland boundary, biologists recorded the dominant plant species in the tree, shrub, woody vine, and herbaceous strata. Dominance was based on aerial coverage on 0.1-acre plots for trees and shrubs and 0.01-acre plots for herbaceous vegetation and woody vines. More than 50 percent of the dominant species recorded required an indicator status of facultative, facultative (+), facultative wet, or obligate wetland plant for the area to be classified as having hydrophytic vegetation. The national list of Hydrophytic Vegetation-Southeast Region issued by U.S. Fish and Wildlife Service was used to identify indicator status of each dominant species (Reed 1988). 4-2 Project Size: Applicant/Owner: ' Investigator: Do Normal Circumstances exist on the site: Is lire site significantly disturbed (Atypical Situation)?

Yes No Hydric Soils Present? - Yes - No ' Remarks: 4-4 1 ¦ Soil test pits ( z 16 inches deep) were dug to determine the location of the hydric or non-hydric soil boundary at each sampling point. The condition of the mineral soils was assessed to determine whether there was an accumulation of organic material in the upper surface, organic streaking below the A horizon, or development of a spodic horizon. At least one positive indicator was required to classify the soil in the area as hydric. The National Technical Committee on Hydric Soils List was also used to determine whether the soil was hydric (U.S. Department of Agriculture 1987). ¦ Determination of wetland hydrology at each sampling point was based on the Soil Conservation Service ¦ description of frequency and duration of inundation for the particular soil type and positive indicators based on field observations. Regional hydrologic indicators were obtained from Wilmington District for application in determining wetland hydrology. A peat, muck, or mucky peat mineral surface layer was required to designate a sampling point as having wetland hydrology. To classify the area as having wetland hydrology, water is required to be present within the upper 12 inches of the soil for about five percent of the growing season. In addition to the regional criteria provided by Wilmington District, at . least one of the primary indicators or two of the secondary indicators of wetland hydrology, as specified in the 1987 manual, were required for positive identification. Primary indicators of wetland hydrology . included observation of inundation, saturated soils in upper 12 inches, sediment deposits, driftlines, water marks, and drainage patterns in wetlands. Secondary indicators included oxidized root channels in upper ¦ 12 inches of soil, water-stained leaves, local soil survey data, FAC-neutral test and other parameters. ¦ 4.3 Results Formal notification of the jurisdictional determination of wetland boundaries delineated was received from ¦ the Wilmington District, COE on 1 March 1994. It was recommended that, where possible, a minimum 50-foot undisturbed buffer be maintained between the proposed upland till and the undisturbed ¦ jurisdictional wetlands located throughout P-949 range. There were 443 acres (39 percent) of jurisdictional wetlands delineated within the 1150 acres of P-949 MPTR (Figure 2-2, Page 2-5). Forest scrub-shrub wetlands accounted for the greatest wetland acreage with 315 acres (27 percent of total-not of wetlands), followed by scrub shrub wetlands with 59 acres (5 percent), forested wetlands with 48 acres (4 percent), and emergent wetlands with 21 acres (2 percent). There were 15 wetland cover types delineated. The greatest area (297 acres) of wetland cover type was pine forest with gallberry or mixed ' bay shrubs growing on saturated sites. 4-5 7 J 5.0 RANGE DESIGN ALTERNATIVES Design considerations included the need to locate the range in an area where unavoidable wetland impacts would be incurred, avoidance and minimization of wetland impacts, and avoidance of cultural resources and threatened and endangered species. Figure 1-2 (page 1-3) and Figure 2-1 (page 2-3) indicate that no alternative for relocation of the entire P-949 MPTR exists because of the surface danger zone requirements, proximity of other proposed ranges, and extensive wetlands throughout the GSRA. The proposed site for P-949 MPTR is the only practicable alternative that could accommodate the range. Three alternatives were considered in design of P-949 MPTR to avoid or minimize wetland impacts. The first alternative was the design prepared by Huntsville Division COE based on preliminary evaluation of the area prior to the delineation of wetlands described herein. The second alternative was to relocate target positions to minimize wetland impacts without requiring major modifications to range design and re-evaluation of the range for qualifying tank gunnery units. The third alternative is the Preferred Alternative and involves relocation of selected targets and tank trail routes to avoid wetlands and minimize impacts. 5.1 Previous Range Design A total of 38.45 acres of wetlands would be impacted under this alternative which involves a total of 85.34 acres of target and road construction (Figure 5-1). The greatest area (28.3 acres) of potential impact would be to pine forest/scrub-shrub wetland cover type which accounted for nine percent of the available cover type area. Nine wetland cover types would potentially be impacted by this range design, although total impacts would be less than one acre on four of the cover types. 5.2 Relocate Targetry The second alternative was eliminated from further consideration because the slight modifications to target locations that were possible without causing major changes to range design and re-evaluation, resulted in an insignificant reduction (16 percent or six acres) in wetland impacts. Any significant reduction in wetland impacts would require relocation of both targets and tank trails, which consequently would result in major range design modifications and range testing. 5-1 `1 H LD c 7 (D Ul I e N? 0 ( (D o a c+ LO (D ° 4 Q1 j ---? c ` ° N \ ?1 ° l ?O g?m P?

The cumulative total area of wetland impacts is 17.25 acres. The Huntsville ' District, COE reduced wetland impacts by avoiding wetlands where possible and minimizing the area of impact through wetlands where impacts were unavoidable. Location of the tank trails further northward ' in the study area than presented was not possible because of cultural resources sites in the northeast portion of the area and potential noise impacts that would result. The limit of the compatible use noise ' contour is approximately represented by the northern boundary of the study area. The redesign would result in 94.59 acres of construction; the area of wetland impacts is 18 percent. Two-thirds of the wetland impacts would occur in PF04/SS3B cover type which occupies an equal percentage (67%) of ' wetlands in the study area. Seven wetland cover types would be impacted under the preferred alternative (Table 5-1). ' The proposed mitigation for these wetland impacts will be provided through development of a mitigation bank located primarily in the southern portion of GSRA. Enhancement of existing wetlands impacted by ' previous construction of drainage ditches and silvicultural practices, restoration of areas where wetland hydrology has been eliminated, and proposed preservation of unique wetlands will be accomplished. 5-3 Table 5-1 Results of Wetland Delineation and Impact Assessment for Preferred Design Alternative on P-949 Multi-Purpose Training Range, Greater Sandy Run Area, Marine Corps Base Camp Lejeune, North Carolina t t COVER TYPE TOTAL COVERAGE (acres) COINCIDENCE W/DESIGN Non-wetland 706.52 77.34 PFO 1 B 04.86 00.00 PFO l /4B 03.52 00.00 PF04B 21.69 00.06 PFO 1 /2C 01.32 00.00 PSS3B 47.53 02.50 PF04/SS3B 297.04 11.49 PEM 1 B 21.00 01.30 PFO/SS3B 04.84 00.54 PSS3/4B 08.23 00.00 PSS4/ 1 B 00.91 00.00 PFO 1 /SS3B 05.19 00.00 PSS3/FO4B 08.06 01.30 PFO 1 /3B 15.65 00.00 PFO l C 00.52 00.04 PSS4B 02.56 00.02 TOTALS 1150.46 94.59 5-4 1 6.0 LITERATURE CITED t 1 6.0 LITERATURE CITED Code of Federal Regulations, Title 40, Title 40, Part 230.
