This project includes additional treatment to improve finished water quality and better management of groundwater supplies through better spacing of wells and balancing water supplies from the Pee Dee aquifer and the Castle Hayne aquifer. The County is proposing to construct a new six million-gallon-per-day (mgd) groundwater treatment plant (WTP) and well field system in the northern part of the County. Fifteen well sites (two wells at each location for a total of 30 wells) will be used to tap into the Pee Dee and Castle Hayne aquifers. Two parallel raw water transmission, mains transmit raw water from the well sites to the WTP. One main will transmit water pumped from the Castle Hayne aquifer, while the other main will transmit water pumped from the Castle Hayne aquifer. The County is also applying for a National Pollutant Discharge Elimination System (NPDES) permit to discharge up to two mgd of membrane concentrate into the Atlantic Intracoastal Waterway (AIWW) at the Figure Eight Bridge. Please note that an Environmental Assessment for this project was prepared by Arcadis G&M of North Carolina, Inc. and submitted to NCDENR; Division of Environmental Health. A Finding of No Significant Impact (FONSI) was issued. Much of the information provided in this narrative was taken from the EA. 2.0 EXISTING CONDITIONS The project area is located in the northern part of New Hanover County, NC (Sheet 1). The 88 square-mile service area encompasses the northern half of New Hanover County with the exception of the US 421 corridor between the Cape Fear and Northeast Cape Fear Rivers (Sheet 2). The project area is bounded by Pender County to the north, the City of Wilmington to the south; the Northeast Cape Fear River to the east, and the Atlantic Ocean to the west. Below is a description of each project area (WTP, well field, corridor, and outfall location). Please see Section 4 of the Environmental Assessment for additional details. 16 a Water Treatment Plant The proposed Water Treatment Plant (WTP) is 44 acres in size and is located off of Old Oak Road in the Ogden area of New Hanover County (Sheet 3). According to the New Hanover County Generalized Soil Survey, the site consists of Johnston loam, Murville fine sand, and Seagate fine sand soil types (Sheet 4). Historically, this site most likely supported a wet pine flatwood community type. However, the area has been significantly altered through time. Several ditches were placed within and around the tract many years ago to drain the site. Only a few wetland pockets now exist within the tract and the ditches have been classified as Waters of the U.S. Ms. Jennifer Frye of the U.S. Army Corps of Engineers signed the wetland survey for this site on March 10, 2006 (Sheet 5). Vegetation within the site has been mowed and consists mostly of fetterbush (Lyonia lucida), sweet pepperbush (Clethra alnifolia), and cinnamon fern (Osmunda cinnamomea) in the herbaceous layer, with a few scattered loblolly pine (Pinus taeda) trees in the canopy. A dirt path approximately 20'-wide runs east-west across the site. Two wells have already been installed within the tract; one located in the southeast corner near Old Oak Road (Well A) and one located in the northwest corner (Well B) of the site. Surrounding land use is residential or undeveloped. The property is located within the New Hanover County jurisdiction. The property is currently zoned for single-family residential (R-15) and is classified as a Wetland Resource Protection Area by the New Hanover County Land Use Plan. All properties adjacent to the site are currently zoned for single-family residential (R-15). A threatened and endangered species evaluation was performed for this site in December of 2004. No federally- protected species were observed. Please see Appendix E of the EA for the complete report. Well Field Sites Fifteen well sites are proposed for the well field (Sheet 6). Two of these are existing well sites at the WTP tract. One well site is located across the road from the WTP. Ten well sites are proposed within Greenview Ranches and four well sites are proposed within the Ogden Park tract. Eight lots within the Greenview Ranches area have been purchased by the County. These undeveloped, forested lots are each approximately five acres in size. Dirt roads were installed many years ago to provide limited access to the area. Plantation Road runs east west between Murrayville Road and terminates just before reaching Market Street. This road is approximately 22' wide and has ditches running parallel to it for a majority of its length. Several smaller dirt roads run north-south through the area. These roads have not been maintained as well as Plantation Road and large potholes (some of which have naturalized back to wetlands) exist throughout them. Ditches (Waters of the U.S.) run parallel to 2 most of these roads. According to the New Hanover County Generalized Soil Survey, these lots consist of Leon fine sand (Sheet 4). Most all of these lots consist entirely of 404 wetlands, however upland areas were found on lots K and L. Furthermore, old ditches that were dug parallel to the existing dirt roads have a minor drainage effect on the lot located furthest north (J). Surrounding land use is residential, agricultural (horse farms), or undeveloped. Vegetation within these lots consists of pond pine (Pinus serotina), gallberry (Ilex glabra), loblolly bay (Gordonia lasianthus), titi (Cyrilla racemiora), and fetterbush (Lyonia lucida). These sites are classified as a Wetland Resource Protection Area by the New Hanover County Land Use Plan. Four additional well sites are proposed within the Ogden Park tract. This tract is 160 acres in size and is located off of Market Street (Sheet 7). The County received a Nationwide Permit 26 in 1993 to fill 5.71 acres of wetlands for park facilities. This acreage plus the natural uplands have been developed into a park that contains baseball fields, soccer fields, tennis courts, playgrounds, rest rooms, a picnic area, a trail, a pet exercise area, and parking (Sheet 8). The wetlands are forested and support Murville fine sand soils (Sheet 9). The uplands. support Leon fine sand soils. The wetland survey for these areas is included in this permit application for final Corps approval. This site is classified as a Wetland Resource Protection Area by the New Hanover County Land Use Plan. Route of Concentrate Main The proposed route of the concentrate main will lead from the WTP, along the right of way of Market Street and then turn right onto the right of way of Porters Neck Road (Sheet 1). The line will then turn right onto Edgewater Club Road and follow this road to the Atlantic Intracoastal Waterway at the Figure Eight Bridge. Outfall Location The project proposes to discharge up to two mgd of membrane concentrate into the Atlantic Intracoastal Waterway (AIWW), on the south side of the Figure Eight Bridge (Sheet 10). The AIWW in this area is classified as SA and Outstanding Resource Water. The SA classification indicates salt waters used for market shellfishing. The ORW classification is for unique and special surface waters that are of exceptional state or national recreational or ecological significance and have exceptional water quality. The average tide range in the AIWW near the Figure Eight Island Bridge is 3.58 feet. The mean water depth at the proposed discharge location is approximately 12 feet at low tide. 3 Freshwater and coastal wetlands have been delineated adjacent to the AIWW and an estuarine Area of Environmental Concern is located 575' landward of mean high water. The portion of the AIWW in which the discharge is proposed is an area that is presently open for shellfishing. The adjacent land use is residential and a boat ramp and pier exist in this vicinity for water access. According to the New Hanover County Soil Survey, upland soils consist of Wakulla and wetland soils are Tidal Marsh muck (Sheet 11). Please see the attached NPDES permit application for additional tide data from this area and a mixing zone analysis (Appendix B). 3.0 PROJECT NEED Please see Section 2 of the Environmental Assessment for a detailed description of the need for the project. 4.0 ALTERNATIVES ANALYSIS Section 3 of the Environmental Assessment describes a no-action alternative, the purchase of raw water from several other sources, and a County-owned surface water treatment plant. At the time that the EA was prepared, the exact location of the well fields had not yet been determined and an alternatives analysis for the specific placement of the wells could not be given. This section of the project narrative describes the factors that dictated the proposed placement of the well fields within New Hanover County. Selection of Well Field Sites The mid-section of New Hanover County was selected as a potential water supply because of aquifer recharge characteristics determined in groundwater evaluations performed by BPA Environmental and Engineering, Inc. in 1995 and by Edwin Andrews & Associates, P.C. in 1996. It is preferable that the wells be placed in an undeveloped area to prevent groundwater contamination. The Greenview Ranches area is located in the target area and is largely undeveloped. However, the majority of the Greenview Ranches area consists of wetlands except for existing dirt roads. To minimize potential impacts, the area was examined to identify lots that contained uplands. The County attempted to purchase lots with uplands, but acquisition was largely dictated by those owners who were willing to sell. Mr. Phil Triece, a local real estate consultant, contacted many landowners to determine who was willing to sell their property. 4 The proposed location of the wells has been centralized as much as possible to reduce necessary roadway improvements between well sites. Only those lots located directly off of three existing roads were purchased. However, the 2001 Concept Design Report indicated that the wells should be spaced between 800 and 1600 feet apart to ensure an even withdrawal of the aquifers. 5.0 PROPOSED PROJECT Please see Section 1 of the Environmental Assessment (Proposed Project Description) for a detailed description of the proposed project. Water Treatment Plant The proposed WTP will be located in the northwestern portion of the property off of Old Oak Road (Sheet 12). The northern portion of the WTP site is reserved for wetlands mitigation to offset impacts from the WTP site, well sites, and other offsite construction activities. The southern portion of the parcel as well as the remaining northern portion of the property is reserved for ULare County uses. The proposed access road will connect with Old Oak Road opposite of Rochelle Road. The main plant entrance and exit will be located along the southern property boundary. It will be equipped with an electric slide gate. All roadways will be asphalt pavement roads. Most roads will be 24-feet wide with the exception of the chemical unloading area, which will have a 12-ft wide road. The visitors parking area will be located adjacent to the Administration Building and will include handicapped spaces for staff and visitors. Parking for WTP staff will be located behind the WTP building. Parking is also proposed for plant operators and maintenance staff near the Chemical Storage Area. The primary treatment process for the WTP will be nanofiltration for softening total organic carbon (TOC) removal and color removal. Separate membrane filtration units will be provided for the two source waters to alleviate the potential for membrane fouling from biological growth or saturated salts. Treatment processes will include cartridge filtration and nanofiltration in series. Following nanofiltration, permeate from both the Pee Dee and Castle Hayne treatment trains will be blended and conveyed to packed tower aerators for removal of carbon dioxide, hydrogen sulfide, and oxidation of any remaining iron in the permeate. Sodium hypochlorite, sodium hydroxide, and corrosion inhibitor 5 will be added and then the finished water will be stored in two 1.0-million gallon clearwells prior to pumping to the distribution system. Two 1-million gallon (MG) circular, pre-stressed concrete tanks will be provided for finished water storage. The proposed tanks will be 100-feet diameter with 17-ft side water depth. Each tank will include curtain-type baffle constructed of Hypalon and stainless steel hardware. Influent connection will be 24-inch diameter and effluent connection will be 30-inch diameter. A tank overflow and drain will be piped to an onsite stormwater detention pond. Level will be recorded and reported to SCADA by an ultrasonic level indicator and transmitter. Well Field Sites Fifteen well sites are proposed within the northern part of New Hanover County (Sheet 6). Both the Castle Hayne and Pee Dee aquifers will be tapped at each well site. Therefore, the 6-mgd WTP will have a total of 30 wells. Two of the well sites (Wells A & B) will be located within the WTP tract. One well site (Well Q) will be located across the road from the WTP. Four well sites (Wells M, N, O, & P) will be located within the Ogden Park Tract. The remaining eight well sites (Wells C, F, G, H, I, J, K, & L) will be located along Plantation Road and two roads 'located perpendicular to Plantation Road. Wells must be placed at least 160 feet from any property line, but will be installed as close to the roads as possible to reduce wetland impacts from the proposed driveway. The width of roadway improvements will be minimal; only a 12' wide gravel road is proposed with 2' shoulders (Appendix C; C10). This will minimize wetland impacts from the road and reduce access by trespassers. Route of Water Main Two parallel raw water transmission mains will be constructed to convey raw water from the well sites to the WTP. One main will convey water pumped from the Castle Hayne aquifer, and the other main will transmit water pumped from the Pee Dee aquifer. Raw water from each aquifer is conveyed to the WTP separately to avoid potential biological fouling. Each raw water transmission main will consist of approximately 17,000 feet (3.2 miles) of line ranging in size from 6-inch to 30- inch, for a total of 34,000 feet (6.6 miles) of main. Both raw water transmission lines will be located mainly within the right-of-way of existing unimproved roads in the well field. 6 Outfall Location The project includes installation of approximately 27,000 feet (5.1 miles) of 16-inch membrane concentrate discharge line. This discharge line will be routed from the WTP site -south to US 17, run northeast along US 17; east on Porters Neck Road, and southeast along Edgewater Club Road toward the bridge to Figure Eight Island. The proposed discharge location is at the Figure Eight Island Bridge at Bridge Road (Sheets 13 & 14). The County is proposing to discharge up to 2 mgd of membrane concentrate to the AIWW. The proposed discharge would include a multi-port diffuser outfall located along the bottom of the AIWW. The diffuser would be within the bridge easement of the USACE's AIWW right-of-way. During the NCSEPA process, the planned design for the effluent outfall structure was to suspend the pipeline under the bridge structure and the have the pipeline rune vertically down the last set of pilings west of the bridge fender system. Consultation with the bridge designers resulted in several logistical problems with attaching the effluent pipeline to the bridge. The issues were as follows: 1. Penetration of the concrete bridge abutment with the pipeline. 2. Uncertainties with attaching suspension elements to an aging concrete girder structure. 3. Foreseeable future maintenance of the bridge that might cause disruption in the use of the outflow pipeline within the next decade. For these reasons it was determined that the best course of action was to make the pipeline a stand-alone structure. The pipeline will be placed underground, utilizing trench and fill construction methods, out to approximately the -10.0 ft mean low water contour, the extend 55' along the seabed to the diffuser structure. The pipeline will be secured by a series of pre-cast 4'x4'xl' concrete collars. The end of the structure will be approximately 60' west of the western bridge fender. During initial construction, it will be necessary to temporarily excavate 225-ft long, by 4-ft deep, by 4-ft wide trench with 3:1 side slopes. The trenching operations will result in the excavation of 550 cubic yards of sandy material and the temporary disturbance of a marine area 35-ft wide by 225 long. The area of temporary disturbance includes the area to be utilized for temporary stockpiling of material. The trench will be dug utilizing a small barge and excavator/dragline. Material will be excavated and temporarily placed on the seabed next to the trench. After the pipeline is installed, material excavated from the trench will be returned to the trench, burying the effluent line. Final grades will be within +/- 1 ft of pre-construction conditions. The mean water depth at the proposed discharge location is approximately 12 feet at low tide. 7 6.0 POTENTIAL ENVIRONMENTAL IMPACTS Direct Impacts The proposed project would permanently impact 1.937 acres of 404 wetlands and 1.108 acres of Waters of the U.S. (Appendix C). In addition, 0.55 acre of 404 wetlands, 0.064 acre of coastal wetlands, and 0.18 acre of open water will be temporarily impacted through the open cut installation of the pipe along two places at Porters Neck Road and at the outfall location adjacent to the Figure Eight Bridge. Excavated material along the concentrate line corridor will be placed in adjacent uplands and the area will be returned to grade and seeded once the pipe has been installed: Excavated material below MHW will be temporarily placed on the seabed next to the trench. After the pipeline is installed, material excavated from the trench will be returned to the trench, burying the effluent line. Final grades will be within +/- 1 ft of pre-construction conditions. This discharge location would be directly adjacent to an open shellfish area, but the effluent is not expected to affect the shellfish. Additionally, this discharge location is not expected to have any navigation issues since the mean water depth at the proposed discharge location is approximately 12 feet at low tide at the diffuser will be 'located adjacent to a bridge fender. Secondary/Cumulative Impacts to Region Secondary impacts to wetlands and water quality could occur during and after construction of the project through erosion and stormwater runoff. . These potential impacts will be minimized by the development and implementation of a Stormwater Plan and a Sedimentation and Erosion Control Plan. These plans will reduce the potential for erosion or runoff into wetlands and other water bodies located off site. The report that accompanies the NPDES permit application evaluates the potential effect that the proposed discharge from the WTP could have on the salinity of the AIWW and the surrounding salt marsh in the vicinity of the outfall location. This report found that because of the rapid dilution and persistent tidal flows in the outfall area, the diffuser will have minimal influence upon the surrounding salinity regime. Therefore, no negative impacts to water quality from the concentrate are anticipated. It is important to note that the project does not intend to stimulate growth in Greenview Ranches, which could create secondary wetland impacts in the region. In fact, it is to the benefit of this project if development in the Greenview Ranches area is managed in order to protect water quality. The County is currently preparing an ordinance that would manage growth in the well site area. 8 Furthermore, this project will not provide utilities to the Greenview Ranches area. The water being withdrawn from these proposed wells will be raw. The project will not supply potable water to the area. In addition, most of the lots in this area will not perk and sewer is not available to this part of the County. Therefore, additional growth within the area will not be stimulated by this project. 7.0 NUTIGATION The applicant has attempted to avoid and minimize environmental impacts as much as possible. Wells will be placed in uplands when possible and will be located as close to the roads as permissible (at least 100' from any property line) to reduce wetland impacts associated with the driveways. The width of access roads will be minimal (12') to further reduce impacts (Appendix C; Sheet C10). No permanent wetland impacts will occur from the installation of the water main. The County will cross wetlands by open cut or by directional drill along Porters Neck Road and Edgewater Club Road (Appendix C; Sheets C5, C6, & C10). After the pipeline is installed, material excavated from the trench will be returned to the trench, burying the effluent line. Final grades will be within +/- 1 ft of pre-construction conditions. To mitigate for the 3.045 acres of proposed permanent impacts to 404 wetlands and 'Vv raters of the U.S., restrictive covenants will be recorded on all remaining wetlands within the well field lots to prohibit any wetland fill beyond what is being requested here. This will protect approximately 25 acres of wetlands. Finally, the applicant plans to restore at least 3.045 acres of freshwater wetlands within the WTP tract off of Old Oak Road (Sheet 12). The applicant is in the process of developing a complete mitigation plan for the proposed restoration. 9 LIST OF SHEETS Sheet 1 Sheet 2 Sheet 3 Sheet 4 Sheet 5 Sheet 6 Sheet 7 Sheet 8 Sheet 9 Sheet 10 Sheet 11 Sheet 12 Sheet 13 Sheet 114 Vicinity map of project area Service area for project Topographic map of WTP and Well Fields SCS Soils Map for WTP and Well Fields Wetland Survey for WTP Aerial photograph of Well Fields Topographic map of Ogden Park Aerial Photograph of Ogden Park SCS Soils Map of Ogden Park Topographic Map of Outfall Location SCS Soils Map of Outfall Location WTP Site Design Diffuser Plan View with Elevations Cross Section of Dili iser Appendix A.

Ownership Status: Page 1 of 1 C-WTP 03/05 APPENDIX B. NPDES Permit Application ' NPDES PERMIT APPLICATION - SHORT FORM C - WTP For discharges associated with water treatment plants Federal ? State ? Private ? Public d 5. Type of treatment plant: ® ? Conventional (Includes coagulation, flocculation, and sedimentation, usually followed by filtration and disinfection) ? Ion Exchange (Sodium Cycle Cationic ion exchange) ® Green Sand Filter (No sodium recharge) ® Membrane Technology (RO, nanofiltration) ii Check here if the treatment process also uses a water softener ? I 6. Description of source water(s) (i.e. groundwater, surface water) Groundwater: 50% acquired from the Pee Dee aquifer and 50% from the Castle Hayne aquifer 7. Describe the treatment process(es) for the raw water: The proposed New Hanover County WTP is a 6-mgd groundwater treatment facility that will treat water from' the Pee Dee and Castle Hayne aquifers. The primary treatment process will be nanofiltration for softening total organic carbon (TOC) removal and color removal. Separate membrane filtration units will be provided for the two source waters to alleviate the potential for membrane fouling from biological growth or saturated salts. In addition, raw water from the Castle Hayne has high iron levels and requires pre-treatment prior to membrane filtration. The total capacity of the Pee Dee treatment train will be 3.0 mgd, which equates to a raw water feed rate of approximately 3.6 mgd. Treatment processes will include cartridge filtration and nanofiltration in series. Three vertical cartridge filter vessels with 5- micrometer filters will be provided for particulate removal. Two nanofiltration units will be provided with a permeate capacity of 2.4 mgd. Source water will be blended with permeate at a rate up to 20 percent (or 0.6 mgd). Design recovery for the nanofiltration units is 80 percent. Three 1,050-gpm feed pumps will be provided for boosting water to a feed pressure of about 110 pounds per square inch (psi). The total capacity of the Castle Hayne treatment train will be 3.0 mgd, which equates to a raw water feed rate of approximately 3.7 mgd. Treatment processes (in series) will include oxidation with potassium permanganate, tray aeration, raw water detention, greensand filtration, cartridge filtration, and nanofiltration. A 300,000-gallon raw water detention tank will provide 2 hours of contact time for potassium permanganate oxidation. Three greensand filters will be provided for iron and manganese removal. The filters are sized based on a filter loading rate of 3.0 gpm/square feet. Three vertical cartridge filter vessels with 5-micrometer filters will be provided for particulate removal. Two nanofiltration units will be provided with a permeate capacity of 2.7 mgd. Source water will be blended, with permeate at a rate up to 10 percent (or 0.3 mgd). Design recovery for the nanofiltration units is 80 percent. Three 1,050-gpm feed pumps will be provided for boosting water to a feed pressure of about 110 psi. Following nanofiltration, permeate from both the Pee Dee and Castle Hayne treatment trains will be blended and the following chemicals will be added: sodium hypochlorite, sodium hydroxide, and corrosion inhibitor. Finished water will then be conveyed to a 2.0- million gallon pre-stressed concrete tank for storage. Three vertical-turbine pumps will be provided to pump finished water into the distribution system. Page 2 of 2 C-WTP 03/05 NPDES PERMIT APPLICATION - SHORT FORM C - WTP For discharges associated with water treatment plants 8. Describe the wastewater and the treatment process(es) for wastewater generated by the facility: The proposed WTP includes a waste treatment system for treatment of backwash waste. Approximately 0.1 mgd of backwash waste will be generated from backwashing greensand filters. Backwash waste will be conveyed to a storage tank for clarification. Following a batch clarification process, clarified water will be decanted and conveyed to the membrane concentrate discharge line. Solids will be pumped to the sewer system or will be stored in a residuals storage tank for off-site disposal vial land application by private contractor. 9. Number of separate discharge points: 1 Outfall Identification number(s) n/a 10. Frequency.of discharge: Continuous ® Intermittent ? If intermittent: Days per week discharge occurs: Duration: 11. Plant design potable flowrate 8.0 MGD Backwash or reject flow 2.0 MGD 12. Name of receiving stream(s) (Provide a map shouring the exact location of each outfWl, including latitude and longitude): Atlantic Intracoastal Waterway (see attached map). 13. Please list all water treatment additives, including cleaning chemicals, that have the potential to be discharged. Sodium hypochlorite (for disinfection) Sodium hydroxide (for pH adjustment) Corrosion inhibitor (for stabilization) 14. Is this facility located on Indian country? (check one) Yes ? No 15. Additional Information: Provide a schematic of flow through the facility, include flow volumes at all points in the treatment process, and point of addition of chemicals.
