Box 1509 • Danville, Virginia 245434509 www.dewberry.com Asheville Regulatory Field Office US Army Corps of Engineers 151 Patton Avenue Room 208 Asheville, NC 28801-5006 RE: The Virginia/ Carolina Regional Water Authority Water Distribution System NCSR 1403 and NCSR 1402 Waterline Installation Request for Nationwide Permit 12 Dear Ms. Jones: Enclosed is the Pre-Construction Notification Form (PCN) required for the request of a United States Army Corps of Engineers (USACE) Nationwide Permit 12 for the proposed Virginia / Carolina Regional Water Authority Water Distribution System. The proposed waterline will run ' parallel to the North Carolina State Roads (NCSR) 1403 and 1402 within the right-of-way for approximately 17,524 linear feet from the intersection of NCSR 1403 and Interstate 21 to the end of NCSR 1402. This proposed segment of the waterline is illustrated in Figure 1. ' The USGS topography map (Figure 1) illustrates that there are two (2) stream crossings associated with the waterline installation. The first stream crossing will result in a temporary ' impact along an unnamed tributary to the New River located at 36.569167 latitude and 81.378333 longitude. Photographs of the stream subject to temporary impact are provided in Figure 2. Stream crossing construction details are provided in Figure 3. The second stream crossing will occur within the Department of Transportation (DOT) right-of-way. The stream crossing is located at 36.566667 latitude and 81.116667 longitude. The waterline will be installed 18" above the existing culvert and will not impact the stream channel. Stream crossing construction details are provided in Figure 4. The National Wetland Inventory (NWI) map was generated from the U.S. Fish and Wildlife Service Wetland Mapper (Figure 5) and used to identify mapped wetlands. The digital NWI maps indicate that there are no wetlands present along the proposed waterline route. The Natural Resources Conservation Service, Web Soil Survey for Alleghany County was used to identify and classify soil types present at the site (Figure 6). None of the soils listed within the project area are listed on the National Hydric Soils List for Alleghany County, North Carolina. The PCN Form is provided in Appendix A. As required in PCN Section F.l.c., supplementary information is provided in Appendix B. Dewberry & Davis, Inc. Ms. Amanda Jones Page 2 ' July 6, 2009 On behalf of the Virginia / Carolina Regional Water Authority, Dewberry & Davis, Inc. ' (Dewberry) requests a Nationwide Permit 12 for the proposed waterline described above with construction details and site information provided in the enclosed PCN.

Page 10 of 10 PCN Form - Version 1.3 December 10, 2008 Version , 1 0 1 1 n 1 ' Appendix B PCN Supplementary Information SECTION 1 PURPOSE AND NEED OF PROJECT 1 1 The Virginia Carolina Water Authority was recently created to serve the needs of Grayson County, Virginia and Alleghany County, North Carolina, including the Towns of Independence and Sparta. The project area includes these two Towns and the interconnecting corridor along U.S. Route 21. The project area is shown in Figure 1 (Exhibit A). The water systems serving the two Towns rely exclusively on groundwater sources. The Town of Independence has four groundwater wells, four water storage tanks, and approximately 84,000 L.F. of water line serving approximately 540 customers: The Town of Sparta has 17 groundwater wells, six water storage tanks and approximately 160,000 L.F. of water lines serving approximately 1,270 customers. The Town of independence has experienced a significant reduction in water capacity and has exceeded on occasion 80 percent of the permitted capacity. The Town of Sparta has approximately 25 percent of their permitted water source capacity remaining but has experienced moderate growth in the last few years. t 1.1 Project Description The proposed project replaces the existing 23 groundwater wells of both Towns with a new water treatment plant utilizing the New River as the water source. The project includes a 1.0 MGD membrane filtration water treatment plant, two water storage tanks, 51,000 L.F. of 12-inch and 8-inch water lines, and four pumping stations. The interconnection between the Towns creates a ' new distribution system in Alleghany and Grayson Counties serving approximately 33 new connections in Alleghany and 21 new connections in Grayson. The proposed locations of these facilities are shown in Figure 2 ' (Exhibit A). ' The new water treatment plant and distribution line, including storage tanks and pumping stations, will be owned and operated directly by the Authority. Improvements within the Towns will be needed to adequately convey water from the new treatment facility throughout each Town. The opinion of probable cost for total project construction is $8,027,000. 1.2 Purpose and Need of Project The Towns have maintained the existing well sources in good working condition, however, there have been reductions in capacity, along with some contamination, that have reduced the water production capabilities for both Towns. The Independence water system has experienced a water capacity Virginia - Carolina Water System Environmental Report Page I reduction from drought conditions and well abandonment due to contamination. The Sparta water system has also experienced some loss in well capacity but has also experienced an increase in water consumption. The Virginia Department of Health Waterworks Regulations requires plans to be developed for new source development whenever the source water production exceeds 80 percent of the rated capacity for a three-month period. A recent report indicated the well source capacity of Independence has been reduced from the permitted capacity and the water system is operating at about 84 percent of rated capacity level. The Regulations also require that systems utilizing wells as the sole source of supply shall provide source capacity of a minimum of 0.5 gallons per minute per equivalent residential connection. This requirement is also not being met. Several test wells were drilled in the early 2000s in the Independence area with unsatisfactory results. The Town of Sparta has approximately 25 percent of their permitted water source capacity remaining but has experienced moderate growth in the last few years therefore reducing the available capacity. Also, in the recent past, the Town has removed four wells from service due to contamination and water production issues. Failure to pursue this project would continue to leave the Towns with inadequate water supplies. This project would also enable both Towns to meet and exceed the drinking water requirements of each state and to provide a safe and adequate water supply. Virginia - Carolina Water System Page 2 Environmental Report SECTION 2 ALTERNATIVES TO THE PROPOSED ACTION Alternatives were evaluated to determine the most feasible approach to provide drinking water to the planning area. These alternatives are discussed in detail in the Virginia Carolina Water System Preliminary Engineering eport, prepared by Lane Engineering, Inc. The following summarizes the alternatives: Alternative I - Groundwater Wells In the past, groundwater has been sufficient to meet the drinking water needs of the planning area. However, several instances of contamination have been realized recently. This alternative explores the continued use of groundwater by developing a new well field in areas where contamination can be controlled through wellhead protection programs. The plan essentially institutes land use controls within the protection zone where activities that could potentially contaminate the groundwater source are prohibited and the plan is based on community involvement. Based on the past and present performance of existing wells and the lack of success in developing new wells, this alternative is questionable in meeting the needs of the Authority. As this is not a viable option, no cost estimate has been prepared. Alternative 2 - Conventional Surface Water Treatment Plant A conventional 1.0 MGD surface water treatment site located near the U.S. Rt. 21 bridge over the New River is proposed for Alternative 2. The safe yield capacity of the New River is more than adequate based on preliminary information from VDEQ and the safe yield analysis performed as part of the PER. The existing water source capacity available from the New River is also more than adequate to meet the Authority's water needs for the next 30 years. The capital cost of the construction of a conventional water treatment plant is $4,242,500. The associated costs of the water storage tanks, pump stations and water lines of approximately $4,729,000 bring the total project cost to $8,971,500. Alternative 3 - Membrane Treatment Plant with Riverbank Filtration Intake This alternative is also based on using the New River as the water source. The groundwater adjacent to the river presents a reliable drinking water source. The natural sediments and soils of the riverbank are used to pre; filter alluvial aquifer groundwater adjacent to the river prior to membrane filtration treatment. This system is described as riverbank filtration where an extraction groundwater well is developed within the zone of influence from the New River. This alternative consists of a combination of innovative technologies to reduce operation costs and also reduce impacts to the environment. The capital cost of the construction of a membrane filtration treatment plant is $3,298,000. The associated costs of the water storage tanks, pump stations and water lines of approximately $4,729,000 bring the total project cost to $8,027,000. Virginia - Carolina Water System Page 3 Environmental Report Alternative 4 - "No Action" This alternative evaluates the consequences of "No Action." The Town of Independence is required by waterworks regulations to develop an additional water source since the water production has reached and exceeded 80 percent of the existing source capacity. Both Towns risk water shortages and service interruptions to their customers if additional water sources are not developed. During service outages, customers would use whatever alternative source was available, posing a real threat to public health. Well development is not considered as a practical or long term solution to meet the Towns' needs. A water treatment plant will allow both Towns to meet and exceed regulatory standards for safe drinking water and will provide for the immediate and future needs of the planning area. Compared to conventional treatment, the riverbank filtration intake and membrane filter aspects of Alternative 3 offer the Authority reduced impacts to the environment and substantial savings in capital and operation costs. Also, any future expansion of water withdrawals would be much less difficult with this alternative. Therefore, Alternative 3 was chosen as the recommended alternative and is therefore the proposed project as discussed throughout this report. Virginia - Carolina Water System Page 4 Environmental Report SECTION 3 AFFECTED ENVIRONMENT / ENVIRONMENTAL CONSEQUENCES Alleghany and Grayson Counties border each other in the Blue Ridge Mountains. They are both predominantly rural, agricultural areas with most commercial and industrial ' developments in close proximity to the Towns and major transportation corridors. The 233 square miles of Alleghany County is located in the northwest corner of North ' Carolina, with a population of 10,000 people. Most of the County is at an average elevation of 2500 to 3000 feet MSL, with its highest peak at 4000 feet MSL. ' Grayson County, located in southwest Virginia, has a population of approximately 17,000 within its 450 square miles. The County is the state's largest in size. Grayson County is also home to the two highest mountains in Virginia, Mount Rogers at 5729 feet MSL and Whitetop Mountain at 5520 feet MSL. Elevations within the County range from 2180 to 5729 feet MSL. The Area of Potential Effect would be immediately adjacent to the water treatment plant ' site, waterline route and the tank and pump station sites. Water line installation will primarily occur along the shoulders of existing Virginia Department of Transportation (VDOT) and North Carolina Department of Transportation (NCDOT) rights-of-way ' along U.S. 21/221. Letters requesting information regarding the presence of any environmental resources within the project area were sent to various regulatory agencies. A list of agencies contacted is contained in Section 5 of this Report and copies of all responses received to date are contained in Exhibit B. Information contained in this Report is based on ' responses from these agencies and the Virginia - Carolina Water System Preliminary Engineering Report. ' 3.1 Land Use / Important Farmland / Formally Classified Lands 3.1.1 Affected Environment Area land uses within the project area are primarily residential with forests and various types of farms. The Natural Resources Conservation Service (MRCS) for both states and the Virginia Department of Conservation and Recreation (DCR) were contacted by letter for their comment on land uses ¦ within the project area. Copies of these agencies' responses are contained in Exhibit B. The project would involve purchasing land, totally less than two acres, on which to construct the pumping station and water storage tank. Waterline construction would generally follow existing Virginia Department of Virginia - Carolina Water System Page 5 Environmental Report Transportation (VDOT), North Carolina Department of Transportation (NCDOT), or other public rights-of-way. 3.1.2 Environmental Consequences The sites for the treatment plant, pump station, water storage tank, and water line corridor were evaluated by NRCS. An on-site visit was also made to the Virginia site by NRCS staff. Subsequently, NRCS has determined that these sites in Grayson County do not contain prime, unique, statewide or local important farmland. NRCS has determined that approximately 14.8 acres of prime farmland in Alleghany County will be impacted by the proposed project. However, only 1.0 acre will be converted by the two pump stations and the water storage tank sites. The temporary construction easement for line work will convert 13.8 acres, which will be restored to its original contour. According to DCR, no State Natural Preserves are within the project vicinity. 3.1.3 Mitigation In order to minimize adverse impacts to the land uses of the project area, activities will follow all applicable local, state, and federal regulations. An erosion and sediment control plan, as described in the Virginia Erosion and Sediment Control Handbook, 1992, Virginia Department of Conservation and Recreation, will be developed, approved, and implemented prior to any construction activity. All disturbed areas will be stabilized and vegetated with native plant species, as soon as practicable to reduce the amount of time barren soils are exposed. 3.2 Floodplains 3.2.1 Affected Environment The project area was compared to Federal Emergency Management Agency Flood Insurance Rate Maps. Copies of these maps, (Grayson County, Virginia, Panel 510243 0145 B) and Alleghany County, North Carolina, Panel 370004 0002 A) are contained in Exhibit A. 3.2.2 Environmental Consequences The proposed water line alignments, water storage tank sites and pump station sites are in areas designated as Zone X - Areas determined to be outside the 500-year floodplain. Virginia - Carolina Water System Page 6 Environmental Report The water treatment plant will not be constructed within the floodplain. However, components of the river bank filtration system, including belowground screens and a well pumping system will possibly be located within the 100-year floodplain. Also, a wellhead pitless adapter that will be sealed at ground surface will possibly be located within the floodplain. All electrical controls associated with the pumping system will be located above the 100-year floodplain. The proposed locations of the water treatment plant, water storage tanks and pump stations are shown on the floodplain maps. 3.2.3 Mitigation The extent of floodplains to be crossed or impacted and the clearing of riparian vegetation will be minimized. When floodplains are encountered, the land will be restored to its original contour and vegetated with native plant species. No permanent structures will be constructed within a floodplain. 3.3 Wetlands 3.3.1 Affected Environment There are no known wetlands within the project area. No wetland areas have been identified by roadside surveys. The U.S. Army Corps of Engineers was contacted for review and comment on wetlands within the project area. A copy of this agency's responses is contained in Exhibit B. 3.3.2 Environmental Consequences Detailed project plans along with site specific information is needed to determine if the proposed activity is within the Corps' jurisdiction. The Corps recommends that efforts be made to avoid and minimize crossings of streams and wetlands to the maximum extent practicable. If it is necessary to cross waters/wetlands, design should comply with the Corps' Nationwide Permits Number 12 for utility line activities. 3.3.3 Mitigation Efforts will be made by the design engineer to relocate utility lines away from wetlands and watercourses. Detailed project plans will be submitted to the Corps to determine if a proposed activity is within their jurisdiction. In the event that a wetland is encountered, heavy equipment will be placed on mats to prevent soil compaction. Machinery must be kept out of Virginia - Carolina Water System Page 7 Environmental Report streams and wetlands when not being actively used. Directional drilling will be used, when possible, from upland locations for placing water lines where stream and/or wetland crossings are unavoidable. In areas where directional drilling is not feasible, the trench backfill must consist of the original material removed. No stockpiled material will be stored on a wetland site and the affected site will be restored to its original contour. All required permits must be obtained prior to construction activity. 3.4 Cultural Resources 3.4.1 Affected Environment The Virginia Department of Historic Resources (DHR) and the North Carolina Department of Cultural Resources State Historic Preservation Office (HPO) were contacted to initiate the consultation process under Section 106 of the National Historic Preservation Act (NHPA). According to an archives search, two archaeological sites and two architectural resources have been previously recorded adjacent to the Area of Potential Effect (APE). 3.4.2 Environmental Consequences Two known or map-projected archaeological resources are in the vicinity of the project. Due to the concern of the impact of this project on these and unrecorded resources, DHR recommended a Phase I identification survey be conducted. A Phase I identification survey for archaeological resources was conducted in May 2007 (report enclosed in Exhibit Q. The survey was conducted within the water treatment plant site, riverbank horizontal screen easement, water storage tank site, two pump station sites and approximately 760 L.F. of proposed water line easement (4.15± acres). "No prehistoric or significant historic period cultural materials were recovered". The two previously recorded archaeological sites lie outside of the project's APE. Neither of the previously recorded architectural resources is currently in existence. Both were replaced during improvements to Highway 21/22 1. According to this report, construction of the facilities and water line, as presently designed, will have no effect on historic properties and no further work is recommended. DHR concurred with this recommendation and issued a determination of "no historic properties affected". DHR also noted that the Eastern Band of Cherokee Indians wish to be consulted on proposed projects in Grayson County. Rural Development has initiated consultation and submitted detailed project information to this tribe. To date, no response has been received from the tribe. Virginia - Carolina Water System Page 8 Environmental Report According to the North Carolina HPO, after review of the proposed undertakings, they are not aware of any historic resources that would be affected. Therefore, this office has no comment on the undertaking as proposed. 3.4.3 Mitigation The development of a plan for the treatment of unanticipated archaeological discoveries in accordance with §800.13 will be incorporated into the construction documents for treating unexpected historical or archaeological discoveries during construction. The plan will include names, telephone and fax numbers of the appropriate County and agency contacts and will also include the following stipulations: a. In the event that a previously unidentified archaeological resource is discovered during ground disturbing activities, all construction work involving subsurface disturbance will be halted in the area of the resource and in the surrounding area where further subsurface remains can be reasonably expected to occur. The SHPO, or an archaeologist approved by their office, will immediately inspect the work site and determine the area and the nature of the affected archaeological property. Construction work may then continue in the project area outside of the site area. Within 10 working days of the original notification of discovery, SHPO will determine the National Register eligibility of the resource. b. If the resource is determined to meet the National Register Criteria (36 CFR Part 60.6), compliance with Section 800.11 of the Council's regulations will be ensured. Work in the affected area shall not proceed until either (a) the development and implementation of appropriate data recovery or other recommended mitigation procedures, or (b) the determination is made that the located remains are not eligible for inclusion on the National Register. 3.5 Biological Resources 3.5.1 Affected Environment The Virginia Department of Conservation and Recreation (DCR), the Virginia Department of Game and Inland Fisheries (VDGIF), the North Carolina Wildlife Resource Commission, the U.S. Army Corps of Engineers and the U.S. Fish and Wildlife Service (USFWS) (Virginia Field Office and Asheville Field Office) responded to request for comments. Copies of responses received to date are contained in Exhibit B. Virginia - Carolina Water System Page 9 Environmental Report 3.5.2 Environmental Consequences According to VDGIF and the Corps, there are currently no documented occurrences of threatened or endangered species in this project area. According to the USFWS County Species List for North Carolina, there are no federally protected species documented within Alleghany County. There are two state threatened species: Logperch (Percina caprodes) and Seep mudalia (Leptoxis dilatata). There are several other state species of concern. According to the USFWS, Virginia Field Office, appropriate habitat may exist for the Smooth coneflower (Echinacea laevigata), the Virginia spiraea (Spiraea virginiana), the Indiana bat (Myotis sodalis), the Virginia northern flying squirrel (Glaucomys sabrinus coloratus), and the Bog turtle (Clemmys muhlenbergii). USFWS recommends surveys within appropriate habitat for these species. A survey of suitable habitat for the Smooth coneflower and the Virginia spiraea was conducted (See report in Exhibit Q. It was determined that suitable habitats for these species are not present. After evaluating the species' habitat requirements, it has also been determined that suitable habitat for the Bog turtle, defined as wetlands and bogs, is not present. The suitable habitats for the Indiana bat and the Virginia northern flying squirrel, as defined by USFWS, are also not present at the project site. Furthermore, the proposed project does not involve tree clearing. Therefore, no impacts to any of the listed species are anticipated. According to DCR, the New River-Brush Creek Conservation Unit is within the project area. This Stream Conservation Unit has been given a biodiversity ranking of B5, which represents a site of moderate significance. The natural heritage resources associated with this site are Moustached clubtail (Gomphus adelphus), Green floater (Lasmigona subviridis) and Kanawha minnow (Phenacobius teretulus). The Green floater was recently listed as state threatened by the VDGIF. DCR recommended coordination with DGIF (letter dated 8/21/07). According to DGIF (letter dated 9/26/07), there are currently no documented occurrences of T/E species in this project area. 3.5.3 Mitigation In order to preserve existing habitat conditions, the N.C. Wildlife Resource Commission recommends the following: Clean Water Act Section 404 Permits and Section 401 Certifications must be followed for any impacts to jurisdictional waters, including wetlands; sediment and erosion control measures will adhere to the design standards for sensitive Virginia - Carolina Water System Page 10 Environmental Report ' watersheds; instream activities should not occur during the fish spawning season of May 1 through July 15 to prevent impacts to fish eggs and fry downstream of the site. Additionally, best management practices (BMPs) will be implemented to prevent sediment from entering the stream and any streams crossings of the unnamed tributary to the New River that parallels NCDOT Route 21/221 will be accomplished by directional bore. NCWRC also recommended against the removal of large trees at the edge of construction corridors and to seed disturbed areas with native plant species that are beneficial to wildlife. Efforts are being made to aesthetically incorporate the water treatment plant in with its surrounding environment. The presence of trees will be important in maintaining the natural surroundings. As noted previously, all disturbed areas will be revegetated as soon as practicable with native plant species. To protect the critical habitats of all threatened and endangered species and the surrounding environment, an erosion and sediment control plan, as described in the Virginia Erosion and Sediment Control Handbook, 1992, Virginia Department of Conservation and Recreation, will be developed, approved, and implemented prior to any construction activity. The above mitigation measures will be implemented to protect all biological resources. 3.6 Water Quality Issues 3.6.1 Affected Environment The proposed project will involve the crossing of the following waters: New River, Brush Creek and other unnamed tributaries. The Virginia Department of Environmental Quality and the North Carolina Wildlife Resources Commission commented on water quality issues. Copies of their responses are contained in Exhibit B. 3.6.2 Environmental Consequences The water treatment plant withdrawal and discharge permitting requirements have been discussed with DEQ. The proposed riverbank filtration system intake will not require a formal permit from DEQ, USACE or Virginia Marine Resource Commission as long as no work occurs within the streambed or banks. The proposed membrane treatment plant does produce filter backwash water that will require a discharge permit from these agencies. The initial conventional treatment process will consist of a screened raw water intake on the riverbank. The intake will include static screens to filter 1 mm particle size with maximum Virginia - Carolina Water System Page 11 Environmental Report velocity of 0.5 fps as required by proposed VDEQ regulations for water withdrawals. The small filter size will prevent damage to aquatic wildlife. DEQ does not anticipate long-term adverse impacts to the water quality of the project area. However, potential short-term adverse impacts resulting from surface runoff due to construction must be minimized. The North Carolina Wildlife Resources Commission recommends the following: adherence to Clean Water Act Section 404 Permits and Section 401 Certifications for any impacts to jurisdictional waters, including wetlands; in the event of withdrawal from the New River, contact with NC Division of Water Resources to discuss any registration or permitting requirements; measures must be taken to protect an unnamed tributary to the New River that parallels NCDOT Route 21/221; sediment and erosion control measures should adhere to the design standards for sensitive watersheds; water conveyance across the New River should be accomplished by pipe suspension under the existing bridge. The U.S. Fish and Wildlife Service, Asheville Field Office recommends the following: maintenance or establishment of minimum 100-foot native forested buffer along each side of perennial streams and 50-foot native buffers along each side of intermittent streams and wetlands; leaving 30 percent of the development area as green space and ensuring that green space is connected to natural resources; all stream crossings be accomplished by using directional boring or a clear-spanning structure; limiting impervious surfaces within residential development. 3.6.3 Mitigation In general, development must incorporate features which prevent significant adverse impacts to the environment. Strict erosion and sediment control measures, as outlined in the Virginia Erosion and Sediment Control Handbook, are critical to water protection. Strict adherence to best management and construction practices must be maintained in order to protect all streams in the project area from impairments due to sediment. A Virginia Marine Resources Commission will be obtained prior to construction. Also, work within jurisdictional waters will adhere to the Clean Water Act Section 404 Permits and Section 401 Certifications. Utilizing riverbank filtration, there will be no withdrawal from the New River. The water line crossing of the New River is proposed to be accomplished by attaching the utility line to the existing bridge. Directional boring of streambeds will be utilized where feasible. Recommendations by the USFWS, Asheville Field Office for establishment of native forest buffers along streams to protect water Virginia - Carolina Water System Page 12 Environmental Report ' quality were reviewed with the Virginia Carolina Water Authority Board. The Authority does not have the legal authority to establish these land use restrictions. However, local authorities have been encouraged to adopt stream buffers and storm management practices to mitigate future development impacts to the water quality. The Alleghany County Board of Commissioners has adopted subdivision ordinances with minimum lot sizes of 3/4 acre. In high water quality areas and watershed areas, the ' minimum lot size increases to 1 acre. These existing ordinances help to protect water quality from degradation associated with future high density land development. For unavoidable impacts, the following practices will be implemented to minimize impacts to wetlands and waterways: the operation of machinery and construction vehicles outside of streambeds and wetlands, the use of directional drilling from upland locations for the installation of utilities, and the use of synthetic mats when in-stream work is unavoidable; stockpiling of material excavated from the trench for replacement if directional drilling is not feasible; and preservation of the top 12 inches of trench material removed from wetlands for use as wetland seed and root stock in the excavated area. Additionally, all streams crossings of the unnamed tributary to the New ' River that parallels NCDOT Route 21/221 will be accomplished by directional bore. The use of herbicides and pesticides during construction or for landscape maintenance will be in accordance with the principles of integrated pest management. The least toxic pesticides that are effective in controlling ' the target species will be used. The use of these chemicals near waterways will be avoided and the use of petroleum products, other chemicals or other hazardous materials will be carefully monitored. 3.7 Coastal Resources There are no coastal resources located within Grayson County, Virginia or Alleghany County, North Carolina. 3.8 Socio-Economic / Environmental Justice Issues ' 3.8.1 Affected Environment The proposed project will serve a wide variety of people. The customers of the water systems will benefit greatly from the provision of an adequate supply of safe, potable water. Virginia - Carolina Water System Page 13 Environmental Report 3.8.2 Environmental Consequence The project will be highly beneficial to the residents of the project area. The provision of potable drinking water will eliminate any potential health risks associated with contaminated groundwater. The project is not anticipated to adversely affect the human health or environmental conditions of the area being served. It is also not anticipated to have a disproportionate effect on LMI communities. 3.8.3 Mitigation Efforts will be made to encourage public participation in the project. Public notices and public meetings will be advertised, in order to promote community involvement. 3.9 Miscellaneous Issues - Air Quality 3.9.1 Affected Environment Project construction will require the use of fossil-fuel burning equipment (i.e., backhoes). The Department of Environmental Quality was contacted for comment on the proposed project. A copy of DEQ's response is enclosed in Exhibit B. 3.9.2 Environmental Consequences According to DEQ, the project is not likely to affect air quality. The use of fossil-fuel burning equipment will produce normal engine exhaust, a by-product of gasoline and diesel fuel combustion. Such emissions are state- and federally-regulated. Normal engine emissions occur everyday and are dissipated into the atmosphere at acceptable quality levels. The emissions produced as part of construction activities are not unusual events, and will not have any adverse impact upon air quality. Completed project activities will not generate any air emissions. 3.9.3 Mitigation During construction, measures must be taken to ensure compliance with federal and state regulations regarding fugitive dust control and open burning. Fugitive dust must be kept at a minimum. Measures, such as application of water to suppress dust and the washing down of construction vehicles and paved roadways immediately adjacent to the construction site, should be implemented. All land clearing debris should be disposed of in an approved manner. Any open burning must comply with 15 A NCAC 2D.1900 and VA Admin. Code (VAC) 9 VAC 5-50-60 Virginia - Carolina Water System Page 14 Environmental Report et. seq., and 9 VAC 5-40-5600 et. seq. The following permits must be obtained and compliance is necessary: NC Permit to construct & operate Air Pollution Abatement facilities and/or Emission Sources and NC Sedimentation Pollution Control Act of 1973. Should any asbestos ' materials be encountered in NC, they will be handled in accordance with 15A NCAC 2D.1110 (a) (1) 7. ' 3.10 Miscellaneous Issues - Noise ' 3.10.1 Affected Environment During project construction, some nuisance levels may be produced by the engines of construction equipment representing short-term negative impacts. 3.10.2 Environmental Consequences The noise levels produced will not be at any health-endangering thresholds. Completed project operations will not produce any noise levels. 3.10.3 Mitigation Contractors will be encouraged to use noise control devices and all ' activities will be limited to normal daylight hours only. 3.11 Miscellaneous Issues - Transportation 3.11.1 Affected Environment ' Construction of the water treatment plant, water storage tanks and pump station will occur on private property. Water line construction will take ' place along existing VDOT, NCDOT U.S. 21/221. 3.11.2 Environmental Consequences According to NCDOT, the thoroughfare plan for this area proposed future widening of this facility to 12-foot lanes. NCDOT requests coordination with the Alleghany County District Engineer's office. Only moderate and temporary disruptions might occur during construction. Project construction activities will add limited tractor-trailer and delivery vehicle traffic to these roads. Completed project activities Virginia - Carolina Water System Page 15 Environmental Report should not produce any increase in the volume of traffic or have any other adverse impacts to transportation within the area. 3.11.3 Mitigation All work with the potential to effect roadways or other transportation facilities will be coordinated with the District office and the local residency office. Specifically, the project will be coordinated with the Alleghany County District Engineer to incorporate future plans. Construction along roadways will require some flagging of traffic, however, road closures will be limited and will be coordinated with VDOT and NCDOT. All permits will be obtained prior to construction. Table 1 summarizes the anticipated long-term impacts to environmental resources within the project area. Table 1.

Justice Issues No No No Air Quality No No No Noise No No No Transportation No No No Virginia - Carolina Water System Page 16 Environmental Report SECTION 4 SUMMARY OF MITIGATION Construction activities will follow all applicable local, state, and federal regulations to minimize / mitigate potential adverse impacts to the environment. This will include, but is not limited to the following: State Erosion and Sediment Control Guidelines - to minimize erosion and sediment/ siltation transport occurrences. Dust Control - roadways and open areas within the project area will be watered as needed to minimize the generation and migration of dust. Working within stream environments - for waterline stream crossings, accepted state guidelines as outlined in stream crossing permits, will be followed to minimize adverse impacts to the aquatic environment. General construction practices - construction activities will follow state and federal safety standards (i.e., OSHA), best management practices and accepted industry guidelines to protect not only the environment, but construction personnel as well. The following permits will be required for the completion of project construction. Also listed is the department from which these permits can be obtained. • Land Use Permit - Virginia Department of Transportation, North Carolina Department of Transportation • Erosion and Sediment Control Permit - Grayson County Building Inspector, Alleghany County Building Inspector • Permit for Road Crossings - Virginia Department of Transportation and North Carolina Department of Transportation • Water System Construction and Operations Permit - Virginia Department of Health • Virginia Marine Resources Commission Permit The Virginia Carolina Water System is not anticipated to significantly impact any environmental resources within the project area. However, in order to minimize potential impacts of the project, the following mitigation measures will be followed: 1. All permits must be obtained prior to any land disturbing activity and compliance with all permits is required. Specifically, compliance with the Virginia Marine Resources Commission permit the Clean Water Act 404 Permit and the 401 Certification is necessary. 2. In order to minimize adverse impacts to the land uses of the project area and to ensure the protection of water quality and all biological resources, activities will Virginia - Carolina Water System Page 17 Environmental Report follow all applicable local, state, and federal regulations. Construction activities will comply with Best Management Practices. A Stormwater Management and Sediment Control Plan, as described in the Virginia Erosion and Sediment Control Handbook, 1992, Virginia Department of Conservation and Recreation, will be developed, approved, and implemented prior to any construction activity. All disturbed areas will be restored to their pre-construction state. Disturbed areas will be stabilized and vegetated with native plant species, as soon as practicable to reduce the amount of time barren soils are exposed. 3. The extent of floodplains to be crossed or impacted and the clearing of riparian vegetation will be minimized. When floodplains are encountered, the land will be restored to its original contour and condition and vegetated with native plant species. No permanent structures will be constructed within a floodplain. 4. Detailed project plans and specifications will be submitted to the USACE for their concurrence prior to the start of construction activities. Should a wetland be encountered, to prevent soil compaction, heavy equipment must be placed on mats and no stockpiled material can be stored on the wetland site. Machinery must be kept out of streams and wetlands when not being actively used. Directional drilling from upland locations will be used for placing water lines where stream and/or wetland crossings are unavoidable. In areas where directional drilling is not feasible, the trench backfill must consist of the original material removed. The top twelve inches of trench material removed from wetlands must be stockpiled on mats or filter cloth for final placement as wetland seed and rootstock in the excavated area. The affected site must be restored to its original contour. All required permits must be obtained prior to construction activity. 6. A plan will be incorporated into the construction documents for the treatment of unanticipated archaeological discoveries. The plan will include the names, telephone and fax numbers of the appropriate County and agency contacts. The plan is discussed in detail in Section 3.4.3. In the event that previously unidentified archaeological resources are discovered, all construction work involving subsurface disturbance will be halted and the steps outlined in the plan will be immediately followed. Instream activities will be avoided during the fish spawning season of May 1 through July 15 to prevent impacts to fish eggs and fry downstream of the site. The removal of large trees will be limited to those necessary for construction. 9. The use of herbicides and pesticides during construction or for landscape maintenance will be in accordance with the principles of integrated pest management. The use of these chemicals near waterways will be avoided and the Virginia - Carolina Water System Page 18 Environmental Report use of petroleum products, other chemicals or other hazardous materials will be carefully monitored . 10. Efforts will be made to encourage public participation in the project. Public ' notices and public meetings will be advertised, in order to promote community involvement. 11. During construction, measures must be taken to ensure compliance with federal and state regulations regarding fugitive dust control and open burning. Fugitive dust must be kept at a minimum. Measures, such as the application of water to suppress dust and the washing down of construction vehicles and paved roadways, must be implemented to prevent adverse impacts to the air quality of the project area. Any open burning must comply with 15 A NCAC 2D.1900 and VA Admin Code (VAC) 9 VAC 5-50-60 et. seq., and 9 VAC 5-40-5600 et. seq. 12. Obtain and comply with the NC Permit to construct & operate Air Pollution Abatement facilities and/or Emission Sources 13. Obtain and comply with the NC Sedimentation Pollution Control Act of 1973 14. Should any asbestos materials be encountered in NC, they will be handled in accordance with 15A NCAC 2D.I I10 (a) (1) 7. 15. In order to minimize noise pollution, contractors will be encouraged to use noise control devices and will have limited noise duration times, occurring only during ' normal daylight hours. 16. The project will be coordinated with the Alleghany County District Engineer to incorporate future widening plans. Flagging of traffic will be required, however, to reduce traffic congestion, road closures will be limited and will be coordinated with VDOT and NCDOT. 17. All solid wastes generated at the site will be reduced at the source, re-used or recycled. All hazardous wastes will be minimized. Otherwise, all solid waste, hazardous waste, and hazardous material will be managed in accordance with all applicable federal, state, and local environmental regulations. 18. The applicant will recommend to local governments the implementation of land use controls for forested buffers, stream resources, infrastructure locations, floodplains, impervious surfaces, storm water treatment, and erosion and sediment control. The applicant will encourage the localities adopt stream buffer regulations as offered by NC USFWS but cannot enforce these measures. Virginia - Carolina Water System Page 19 Environmental Report SECTION 5 CORRESPONDENCE Letters concerning environmental resources were sent to various regulatory agencies requesting their comment on the proposed project.

Exhibit C contains the "Phase I Identification Survey for Cultural Resources" and "Vegetation Analysis" - Survey for Virginia spiraea and Smooth coneflower. Virginia - Carolina Water System Page 21 Environmental Report Virginia Carolina Water System Environmental Report - Addendum #1 The Virginia Carolina Water System Environmental Report (dated June 2007, revised February 2008) was accepted as an Environmental Assessment by USDA Rural Development on February 28, 2009. Since that time, design changes have been made. The proposed site for the water treatment plant has been moved. This change was necessary in order to utilize the proposed treatment method of riverbank filtration. Another factor for the move was the inability to reach an agreement with the property owner. The new site is approximately two miles downstream and is still located in Virginia. An agreement has been reached with the property owner and the site has been approved by the Virginia Department of Health. Letters and maps detailing the proposed change were sent to the following for review: Natural Resources Commission Service, U.S. Fish and Wildlife Service, Virginia Department of Conservation and Recreation, Virginia Department of Game and Inland Fisheries, and Virginia Department of Historic Resources. Copies of these agencies' responses follow. The Department of Historic Resources (DHR) requested a Phase I Identification Survey for Cultural Resources at the new site. This survey was performed and the report was submitted to DHR. A determination of "no historic properties affected' was made by DHR. A copy of the Phase I Survey report follows this addendum. No new comments were made by the other review agencies. Based upon the comments received, the new location of the water treatment plant will not significantly impact the environment of the project area. 1 1 03/11/2009 10:04 FAX 2766266920 APRIL LANE 121002 U.S. Department of AgrleultUre FARMLAND CONVERSION IMPACT RATING PART 1(To be compNho by Fed" Agency) .

Box 1340 Chilhowie, VA 24319 Re: Virginia Carolina Water System Dear Ms. Lane: The Department of Conservation and Recreation's Division of Natural Heritage (DCR) has searched its Biotics Data System for occurrences of natural heritage resources from the area outlined on the submitted map. Natural heritage resources are defined as the habitat of rare, threatened, or endangered plait and animal species, unique or exemplary natural communities, and sigrrificant geologic formations. According to the information currently in our files, the New River-Brush Creek Conservation Unit is within the project area. Stream Conservation Units (SCUs) identify stream reaches that contain aquatic natural heritage resources, including 2 miles upstream and 1 mile downstream of documented occurrences, and all tributaries within this reach. SCUs are also given a biodiversity significance ranking based on the rarity, quality, and number of element occurrences they contain. The New River-Brush Creek SCU has been given a biodiversity ranking of B5, which represents a site of general significance. The natural heritage resource associated with this site is: Gomphus adelphus Moustached Clubtail G4/SI/NL/NL Adult Odonata (dragonflies and damselflies}, commonly seen flitting and hovering along the shores of most freshwater habitats, are accomplished predators. Adults typically forage in clearings with scattered trees and shrubs near the parent river. They feed on mosquitoes and other smaller flying insects, and are thus considered highly beneficial. Odonates lay their eggs on emergent vegetation or debris at the water's edge. Unlike the adults, the larvae have an aquatic larval stage where they typically inhabit the sand and gravel of riffle areas. Wingless and possessing gills, they crawl about the submerged leaf litter and debris stalking their insect prey. The larvae seize unsuspecting prey with a long, hinged ••gtaspet' that folds neatly under their chin When larval development is complete, the aquatic larvae crawl from the water to the batik, climb up the stalk of the shoreline vegetation, and the winged adult emerges (Hoffman. 1991; Thorpe and Covich 1991). Because of their aquatic lifestyle and limited mobility, the larvae are particularly vulnerable to shoreline disturbances that cause the loss of shoreline vegetation and siltation They are also sensitive to alterations that result in poor water quality, aquatic substrate changes, and thermal fluctuations.

Dear Ms. Lane: This letter is in response to your request for updated information related to the presence of threatened or endangered species in the vicinity of the above referenced project. There are currently no documented occurrences of threatened or endangered species in this project area. Information about fish and wildlife species was generated from our agency's computerized Fish and Wildlife Information System, which describes animals that are known or may occur in a particular geographic area. Field surveys may be necessary to determine the presence or absence of some of these species on or near the proposed area. Also, additional sensitive animal species may be present, but their presence has not been documented in our information system. Endangered plants and insects are under the jurisdiction of the Virginia Department of Agriculture and Consumer Services, Bureau of Plant Protection. Questions concerning sensitive plant and insect species occurring at the project site should be directed to Keith Tignor at (804) 786-3515. The Virginia Department of Conservation and Recreation, Natural Heritage Program, maintains a database of natural heritage resources, including the habitat of rare, threatened, or endangered plant and animal species, unique exemplary natural communities, and significant geologic formations, that may contain information not documented in this letter. Their database may be accessed from http://www.dcr.statc.va.us/dnh/nhi.info.litm, or by contacting S. Rene Hypes at (804) 371-2708. This letter summarizes the likelihood of the occurrence of endangered or threatened animal species at the project site. If you have more questions in this regard, please contact me at (804) 367-1185.

Our comments are being. sought by Lane Engineering. Inc. as pan of the emironmental review required by USDA - Rural Development. Although the study area includes some landtorms considered moderate to high potential to contain cultural resources, the survey did not identify any intact archaeolouical sites or potential for deeph buried deposits within the Area of Potential Effects. The consultant recommends that no further cultural resources investigations be conducted. We concur with this recommendation. Accordingh. a detemsination of no historic properties a(Jczted is appropriate for this project. Thank you for informing our office of the change to this project and your continued consideration of historic properties during the planning of this project.

Notice of a Finding of No Significant Impact The USDA Rural Utilities Service has received an application for financial assistance from the Virginia/Carolina Water Authority. The proposed project consists of the construction of a 1.0 MGD membrane filtration water treatment pant, two water storage tanks, 51,000 L.F. of 12-inch and 8-inch water lines, and four pumping stations. The proposed construction will occur in Grayson County, Virginia and Alleghany County, North Carolina. As required by the National Environmental Policy Act, the Rural Utilities Service has assessed the potential environmental effects of the proposed project and has determined that the proposal will not have a significant effect on the human environment and for which an Environmental Impact Statement will not be prepared. The basis of this determination is: (1) impacts will be temporary in nature due to construction; and (2) the requirement of mitigation measures. In order to avoid or minimize any adverse environmental impacts, the Rural Utilities Service will require the applicant to incorporate the following mitigation measures into the proposed project's design: The extent of floodplains to be crossed or impacted and the clearing of riparian vegetation will be minimized. When floodplains are encountered, the land will be restored to its original contour and condition and vegetated with native plant species. No permanent structures will be constructed within a floodplain. A plan will be incorporated into the construction documents for the treatment of unanticipated archaeological discoveries. The plan will include names, telephone number and fax numbers of the appropriate County and agency contacts. In the event that previously unidentified archaeological resources are discovered, all construction work involving subsurface disturbance will be halted and the steps outlined in the plan will be immediately followed. Instream activities will be avoided during the fish spawning season of May 1 through July 15 to prevent impacts to fish eggs and fry downstream of the site. Copies of the Environmental Assessment can be reviewed or obtained at USDA Rural Development, 140 Highland Drive, Suite 5, Lebanon, VA 24266. For further information, please contact Robert B. Hilt at (276) 889-4650, Ext. 122. Any person interested in commenting on this proposed project should submit comments to the address above by May 1, 2008.
