(CEI), in conjunction with Black & Veatch and Hazen & Sawyer, has prepared the attached Pre - Construction Notification for the Winston- Salem/Forsyth City- County Utilities Commission (CCUC). Enclosed is an application for a Section 404 Nationwide Permit 12 and a Section 401 Water Quality Certification No. 3884. The CCUC is planning sewer infrastructure improvements in the South Fork and Muddy Creek basins in southern Winston -Salem (Figure 1). The purpose of this project is to address critical needs of the Muddy Creek basin and South Fork basin collection system identified through the CCUC wastewater master planning process. The project is proposed to manage wet weather flow, address predicted 2041 growth in the service area, and improve water quality through the reduction of sanitary sewer overflows (SSO's). The South Fork basin service area is approximately 68 square miles and encompasses the southeastern portion of Forsyth County. The service area includes the City of Winston - Salem, Forsyth County and the Town of Kernersville. The Muddy Creek basin is approximately 130 square miles and includes the western and northern portions of the CCUC wastewater service area. The proposed project consists of the construction of the Muddy Creek Consolidated Influent Pump Station (MCCIPS), Muddy Creek WWTP Influent Transfer Force Main (MCTFM), improvements to the South Fork Interceptor (SFI), Elledge WWTP improvements, and expansion of the Kerners Mill Pump Station and force main. These project components are shown in Figure 1. Additional segments of the SFI (shown in gray on Figure 1) were initially studied and included in the wetland delineation for this project, but are currently not anticipated to be designed or constructed in the next 5 years. Impacts to Waters of the U.S. are not anticipated to occur during construction of the Elledge WWTP improvements or the expansion of the Kerners Mill Pump Station and force main. Therefore, these projects are shown on Figure 1 and included here for reference as they are a portion of the overall South Fork basin improvements but do not require 404/401 permits. As we discussed, the project components will be constructed under separate contracts, and the SFI improvements are able to function as an independent project without the construction of the MCCIPS and force main. The proposed construction schedule as of August 2014 is as follows.

Proposed Facilities and Actions The proposed project will include construction of the Muddy Creek Consolidated Influent Pump Station located at the Muddy Creek Wastewater Treatment Plant (WWTP), Muddy Creek Pump Station force main, improvements to the South Fork interceptor, and an expansion of the Kerners Mill Pump Station force main The Muddy Creek Pump Station will have a capacity of 126 rmllion_gallons per day (mgd) and will include new preliminary treatment and influent pumping capabilities It will be located on the existing Muddy Creek WWTP site and will transfer screened and degrrtted }wastewater flow, to the Archie Elledge WWTP via the proposed 30 -inch diameter and 4 6 mile long Muddy Creek Pump Station force main The-project will also include equalization day tanks, storm equalization basins, transfer pumps, odor control system, and miscellaneous appurtenances at the Muddy Creek WWTP site Proposed improvements to the South Fork interceptor will address critical sewer by�replacement of some segments and a parallel interceptor for other segments The proposed interceptor improvements will include approximately 24,290 linear feet (1 f ) of 60 -inch sewer, 6,6001 f of 42 -mch sewer, 14,1001 f of 36 -inch sewer, 9,1001 f of 30 -inch sewer, 8201 f of 24 -inch sewer, 1,7701 f of 21 -mch sewer, 15801 f of 18 -inch sewer, and 1,5001 f of 15 -mch sewer The project will also expand the Kerners Mill Pump Station to a firm capacity of 12 6 mgd and total capacity of 15 7 mgd with all pumps running, a 24 -inch force main parallel to the existing force main, and a 1,600.1 f expansion of the existing force main Funding Status The estimated total cost for the project is $112,021,454 The City /County Utilities Comnussion (CCUC) is applying for a Clean Water State Revolving Fund ( CWSRF) loan of $50;000,000. The CWSRF loan will be used for installation of mechanical bar screens and grit removal systems, influent pumps, equalization tanks, flow meters, transfer pumps, transfer force main, forcemam flow meter, odor control system, and all the related appurtenances The remaining,$62,021,454 of the project will be funded by local bonds B. ExistinzEnvironment Topography and Soils Forsyth County is located in the Piedmont Physiographical Province The Muddy Creek Pump Station site,slopes from approximately'692 feet to 688 feet above mean sea level Elevations in the Muddy Creek force main,comdor range from 680 feet to 720 feet above mean sea level Elevations, in the South Fork interceptor corridor range from 690 feet to 826 feet above mean sea level. The Kerners Mill Pump Station site el'eyations range from 855 feet to 822 feet above mean sea level The elevations in the Kemers Mill force main corridor range from 825 feet to 950 feet above mean sea level Portions of the project are located in floodplams Soils in the area include the following associations Chewacla- Wedhadkee- Congaree, which are somewhat poorly drained and poorly drained loamy surface layer with well - drained loamy subsoil, Pacolet- Cecil, which are,located in uplands and have a well - drained loamy surface layer and clay subsoil, Madison- Pacolet, which have well - drained loamy surface layer and clayey subsoil, Wedowee - Louisburg with have a loamy surface layer and clayey subsoil or sandy surface and subsoil, and Wilkes -Enon associations, which have a well - drained loamy surface layer and clayey subsoil Surface Water The project area is located primarily in the Lower Yadkin River Headwaters Sub -Basm (HUC 03040101) There are numerous streams in, the project area with classifications of B, C, WS -III, and WS -IV Primary water quality concerns are associated with densely populated areas with large amounts -of impervious areas Water Supply- Drinking water is provided by the CCUC, which operates three water treatment plants,that draw water from the Yadkin River and SalermyLake for distribution in the project area C. Existing Wastewater Facilities The CCUC wastewater service included three sewersheds the Muddy Creek basin, Archie Elledge'basm, and South Fork basin The system includes`ihe Muddy Creek WWTP, Archie Elledge WWTP, over 50 pump stations, and approximately 1,790 miles of sanitary sewer ranging from two inches to 66 inches in diameter The Muddy.Creek WWTP`was originally built in 1986 and was expanded in 1997 from,a capacity of 15 mgd to 21 mgd This, WWTP discharges primarily to the Yadkin River and has a second wet - weather discharge into Muddy Creek The facilityas'in adequate working condition except for the preliminary treatment facilities, which has exceeded its useful life The Archie Elledge WWTP was originally built in 1956 and has undergone numerous upgrades to the current permitted - capacity of 30 mgd. The facility is in good.condition The South Fork Pump Station was commissioned in 2006 and,has a fern capacity of 11 mgd and total capacity of 14 4 mgd. It pumps approximately six to seven mgd to the Archie Elledge WWTP and one to two mgd to the Muddy Creek WWTP The station has significant operational issues including pump failures and odor complaints The Kerners Mill Pump,Stationywas comnussioned,m 1981 and has a firm capacity of 5.7 mgd andiotal capacity of 7 3 mgd It,is in, good operating,condition D. Need for Proposed Facilit %s, and Actions The CCUC's wastewater master planning process,has identified critical needs in,the South Fork basin collection system to meet anticipated demand and avoid sanitary sewer overflows (SSOs) The,existing mfrastructureAS,not sized to handle,peak wet"weather flow, and the treatment capacity of the Muddy Creek WWTP is not available to both the South Fork and Muddy Creek basins The`proposed project'will address SSOs in`the South Fork and Muddy Creek basms and will allow for transfer of wet weather flows for distribution • between the two WWTPs as needed 2 E. Alternatives - Analysis Two alternatives analyses were conducted The.first addressed the South Fork and Muddy Creek wastewatei infrastructure expansion alternatives, and ithe second addressed the Kemers Mill Pump Station expansion. Each analysis,ns_discussed below South fork and�Muddy Creek,Alterriatives No- Action Alternative The No- Action Alternative would mean continuing to rely on existing sewer infrastructure The Muddy Creek WWTP does not have capacity to treat projected future flows in, the Muddy Creek.and South Fork sewersheds. The growing need for wastewater - treatment would require package,plants or septic tanks, and'SSOs would be a significant concern This alternative was rejected because it does not meet the project needs Ex and- South,Fork Lift Statnoneto TransferTlow to.ArchreElled e WWl?P The South Fork Lift Station was designed to be expandable from 14 4 mgd to 15 mgd The site is adjacent to two schools, thus limiting the potential for additional expansion To prevent flow violations, this alternative would- still,,require a transfer pump station at Muddy Creek to transfer,flow to the Archie Elledge WWTP This ,alternative was rejeeted,because it does not meet the project needs Construct a New Abbotts Creek Pump-Station and WWTP , This alternative would construct a new WWTP'to treat flows from the upper South Fork basin and would discharge'to Abbots Creek, which is a WS -111 stream,and m impaired for fish community bloclassificatron This alternative could-have significant water quality impacts Furthermore, it would -not alleviaterthe, projected excess flow to Muddy.Creek WWTP This alternative was rejected because-it does not meet the project needs Construct a NewhYadkin RiverWWTR in Davie or Davidson Counties This alternative would construct a ne, WWTP south ofthe Muddy Creek WWTP discharging to the Yadkin River This alternative would require inter= county agreements that the Davie and Davidson Counties, are reluctant to make at this time, and it would require having the,new WWTP operational by 2021 to -meet anticipated flows. The alternative would also have environmental impacts associated with converting agricultural land to a developed use Based -on the environmental impacts,and difficulties with getting a plant constructed and' operational within the necessary tnmeframe, this alternative was rejected Elledge WWTP: This alternative make improvements at the existing Muddy,Creek WWTP including aapump,station to,transfer flow to Archie Elledge WWTP, equalization tanks for wet weather flow, and a force main from Muddy Creek WWTP to Archie Elledge WWTP. Improvements to,crntical areas of the South Fork interceptor would be,mcluded with this alternative. The majority of the project would occur on land already used for wastewater operations, and',environmental impacts, will be minimal This alternative is preferred because it satisfies the need for the project with minimal environmental impacts Kerners Mill Pump Station Expansion Alternatives. No- Action Alternative. This alternative would make no improvements to the Kerners Mill Pump Station or the related force main infrastructure. The pump station does not have adequate capacity to meet anticipated needs and would lead to SSOs This alternative was rejected because it,does not meet the project -needs Add Two,Submersnble Pumps and Extend Existing Force Main. This alternative would increase capacity of the existing pump station by adding two new pumps to increase the capacity to 11.6 mgd and extending the force,mam approximately 1,6001 f This alternative woul&nieet capacity needs through 2016 but not through the full planning period, of 2021 The alternative was rejected because it does not meet the,project needs Mann --this alternative wouldadd tw,o submersible pumps and reconfigure ,the wet wells, add a 16 -inch parallel force main, and add a 1,6001 f extension to the force main This project would meet the project needs nd'has similar environmental impact as the, preferred alternative, but operating and maintenance costs would be significantly higher. Mann- This alternative would -add onexsnbmersible pump to reconfigured wet wells, add a 24- inch force main, and add a 1,6001 f , extension to the existing force main for a firm capacity of 12 6 mgd This is the preferred alternative because it meets the project needs with mammal environmental impacts and has lower costs than similar alternatives F. Environmental Consequences and Mitigative Measures Topogr by and Soils. Impacts to soil and topography will be,related primarily to construction and will not be. significant Impacts will be mmnmized'by restoring disturbed areas to original grade after construction and by implementing a North,Carol'ina Department of Environment, and Natural Resources (NCDENR)- approved and County - approved Erosion and Sedimentation control plan and other provisions of the- Sedimentationvand'Pollutnon Control Act of 1973 Land Use. Mminal changes or umpaets to land use are expected because the project will occur in areas that already developed for wastewater infrastructure or within or adjacent to existing utility corridors except for one portion of the South Fork force main corridor Wetlands Construction activities may have minor, temporary impacts to wetlands Impacts will be minimized by narrowing construction corridors in wetland areas and implementing BMPs Construction will be in accordance with a NCDENR- approved and County- approved Erosion and Sedimentation Control Plan and other provisions of'the Sedimentation Pollution Control Act of 1973 to minimize impacts from erosion and sedimentation The U S Army Corps of Engineers was consulted and did not object to the project (July 10, 2013, Action ID,No SAW 2013 - 01274) 4 Important Farmlands Direct unpacts to important farmlands, will be minimal The pump stations,are not located on agricultural lands Portions of the sewer corridors traverse prime farmland currently in agricultural use These areas may have minor, temporary impacts during construction, but there will be no loss of4armland acreage as a result of the project Public Lands and Scenic. Recreational and State Natural Areas. Impacts to public lands or ,scenic,, recreational, or state natural areas will be minimal and temporary, during construction activities Impacts to two bike paths that cross the pipelinecorridors will be minimized b_y utilizing trenchless, technologies in those areas Cultural Resources. In a memorandum dated July 29, 2013 (No ER 13- 1382), the North Carolina State Historic Preservation Office (SHPO) stated that no historic resources, would be impacted by the proposed project Air Ogg t Temporary impacts to, air quality, including particulates and> vehicle exhaust emissions, will,result from construction activities. Proper vehicle maintenance, wettmg of exposed soil, and prompt soil stabilization,will minimize these,impacts Agnew emergency generator will have minimal impact Noise Levels There will, be a temporary increase in noise related to construction equipment Construction activities will be limited to 6 00 am to 7.00 pm Monday through Friday to the extent practicable Norse impacts from emergency generators and the new pump station will be negligible Water Resources Negative operational impacts to water resources are,not anticipated There is the potential for temporary impacts due.to erosion and sedi mentation,dunng construction To minimize such impacts, all construction will be in accordance with a NCDENR- approved and County- approved Erosion,and Sedimentation Control Plan and other, provisions of the Sedimentation Pollution,Control Act of 1973 Best Management Practices- (BMPs) will be implemented to,mini nize impacts from stormwater Forest Resources: The project will require clearing of approximately-two acres. of forested land adjacent to existin&maintained corridors for pipe installation Approximately 13 acres will be allowed to transition naturally back to mature forest. Shellfish or Fish and Their Habitats Impacts to shellfish, fish, and their habitats are not expected to be significant. Construction impacts will be minimized, through adherence to a NCDENR- approved and County- approved Erosion and Sedimentation.ControbPlan and other provisions of the Sedimentation Pollution Control Act of 1973 Wildlife and Natural Vegetation Impacts to wildlife and natural vegetation will be,temporary due to construction activities As requested by North Carolina Wildlife Resources Commission (September 27, 2013), the contractor will conduct a survey for the bog turtle prior to commencing construction activities to prevent impacts to the protected species 5 Introduction of Toxic Substances. introduction of toxic substances from construction activities is possible from vehicle fluids Such impacts will be minimized by proper vehicle maintenance and proper collection of and disposal of fluids The U S Fish and Wildlife Service reviewed the proposed project and concluded that the requirements of Section 7(a)(2),of the Endangered Species Act have been fulfilled (July 23, 2013, Log No 4 -2 -13 -312). The North Carolina Wildlife Resources Commission, Natural Heritage Program, and DWR Winston -Salem Regional Office, and U.S Army Corps of Engineers concur with the proposed project The North Carolina Department of Cultural Resources is not aware of any properties of architectural, historical, or archaeological significance, that would be affected by the project G. Public Participation, Sources Consulted A public meeting was held on September 21,, 2013 including an informational presentatzon�about the meeting There were no objections to the project The current user charge for a typical customer is $38 71 per month for 5,000 gallons for sewer and, water The proposed project is expected to cause an increase of $8 04 per month for a total of $46 75 Sources consulted about this project for information or concurrence included 1) City of Winston -Salem 2) Forsyth County 3) North Carolina Department of Environment and Natural Resources - Wildlife Resources Commission -DWR Winston -Salem Regional Office - Division of Au Quality - Division of Environmental Health - Division of Water Resources Public Water Supply Section - Division of Forest Resources -Office of Legislative and Intergovernmental Affairs 4) North Carolina Department of Cultural Resources 5) North Carolina State Clearinghouse 6) U S Fish and Wildlife Service 7) U S.
