This SWMP identifies the specific elements and minimum measures that the Town of Woodfin will develop, implement, enforce, evaluate and report to the North Carolina Department of Environmental Quality (NCDEQ) Division of Energy, Minerals and Land Resources (DEMLR) in order to comply with the MS4 Permit number NCS000440, as issued by NCDEQ. This permit covers activities associated with the discharge of stormwater from the MS4 as owned and operated by the Town of Woodfin and located within the corporate limits of the Town of Woodfin. In preparing this SWMP, the Town of Woodfin has evaluated its MS4 and the permit requirements to develop a comprehensive 5-year SWMP that will meet the community’s needs, address local water quality issues and provide the minimum measures necessary to comply with the permit. The SWMP will be evaluated and updated annually to ensure that the elements and minimum measures it contains continue to adequately provide for permit compliance and the community’s needs. Once the SWMP is approved by NCDEQ, all provisions contained and referenced in this SWMP, along with any approved modifications of the SWMP, are incorporated by reference into the permit and become enforceable parts of the permit.

Signature: Print Name: Title: Signed this ____ day of 20____ . NCS000440 SWMP Town of Woodfin January 2021 Page 3 PART 3: MS4 INFORMATION 3.1 Permitted MS4 Area This SWMP applies throughout the corporate limits of the Town of Woodfin, including all regulated activities associated with the discharge of stormwater from the MS4. The map below shows the corporate limits of the Town of Woodfin as of the date of this document. 3.2 Existing MS4 Mapping The current MS4 mapping is unavailable. The Town of Woodfin is working with Land of Sky Regional Council on development of a map to include ditches, catch basins, manholes and other storm system infrastructure. The map will be available in Fall 2021. 3.3 Receiving Waters The Town of Woodfin MS4 is located within the French Broad River Basin and discharges directly into receiving waters as listed in Table 2 below. Applicable water quality standards listed below are compiled from the following NCDEQ sources: o Waterbody Classification Map o Impaired Waters and TMDL Map o Most recent NCDEQ Final 303(d) List Table 2: Summary of MS4 Receiving Waters Receiving Water Name Stream Index / AU Number Water Quality Classification 303(d) Listed Parameter(s) of Interest French Broad River 6-(54.75)c B N/A Beaverdam Creek 6-82 C N/A NCS000440 SWMP Town of Woodfin January 2021 Page 4 3.4 MS4 Interconnection The Town of Woodfin MS4 is not interconnected with another regulated MS4 and directly discharges to the receiving waters as listed in Table 2 above. 3.5 Industrial Facility Discharges The Town of Woodfin MS4 jurisdictional area includes the following industrial facilities which hold NPDES Industrial Stormwater Permits, as determined from the NCDEQ Active NPDES Stormwater Permit List and/or Active Stormwater Permits Map. Table 3: NPDES Stormwater Permitted Industrial Facilities Permit Number Facility Name NCG050238 Silver Line Plastics LLC NCG080661 Republic Services of North Carolina LLC NCG110158 Metropolitan Sewerage District of Buncombe County NCG030134 Thermo Fisher Scientific LLC 3.6 Non-Stormwater Discharges The water quality impacts of non-stormwater discharges have been evaluated by the Town of Woodfin as summarized in Table 6 below. The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality. The Town of Woodfin has evaluated residential and charity car washing and street washing for possible significant water quality impacts. Street washing discharges are addressed under the Pavement Management Program in Part 10 of this SWMP. The Division has not required that other non-stormwater flows be specifically controlled by the Town of Woodfin. Wash water associated with car washing that does not contain detergents or does not discharge directly into the MS4 is considered incidental. However, these types of non-stormwater discharges that do contain detergents have been evaluated by the Town of Woodfin to determine whether they may significantly impact water quality. Table 4: Non-Stormwater Discharges Non-Stormwater Discharge Water Quality Impacts Water line and fire hydrant flushing Incidental Landscape irrigation Incidental Diverted stream flows Incidental Rising groundwater Incidental Uncontaminated groundwater infiltration Incidental Uncontaminated pumped groundwater Incidental Uncontaminated potable water sources Incidental NCS000440 SWMP Town of Woodfin January 2021 Page 5 Foundation drains Incidental Air conditioning condensate Incidental Irrigation waters Incidental Springs Incidental Water from crawl space pumps Incidental Footing drains Incidental Lawn watering Incidental Residential and charity car washing Possible Flows from riparian habitats and wetlands Incidental Dechlorinated swimming pool discharges Incidental Street wash water Possible Flows from firefighting activities Incidental 3.7 Target Pollutants and Sources During the first year of the SWMP, the Town of Woodfin will develop and distribute educational materials to the community to educate schools, homeowners and businesses to be aware of stormwater pollutants from yards and streets as well as the importance of keeping drains and ditches free of debris. Additionally, through community outreach, the Town will identify and provide education on other target pollutants such as lawn care activities and illicit connections.

The Town is in a transition period with staff turnover and reorganization. During Year 2 of this plan, the Town will revisit additional opportunities for funding and staffing to meet the requirements of the MS4 Permit. 4.3 Shared Responsibility The Town of Woodfin will share the responsibility to implement the following minimum control measures, which are at least as stringent as the corresponding NPDES MS4 Permit requirement. The Town of Woodfin remains responsible for compliance if the other entity fails to perform the permit obligation, and may be subject to enforcement action if neither the Town of Woodfin nor the other entity fully performs the permit obligation. Table 9 below summarizes who will be implementing the component, what the component program is called, the specific SWMP BMP or permit requirement that is being met by the shared responsibility, and whether or not a legal agreement to share responsibility is in place.

The Buncombe County Sediment and Erosion Control Program effectively meets the maximum extent practicable (MEP) standard for Construction Site Runoff Controls by permitting and controlling development activities disturbing one or more acres of land surface and those activities less than one acre that are part of a larger common plan of development as authorized under the Sediment Pollution Control Act of 1973 and Chapter 4 of Title 15A of the North Carolina Administrative Code. PART 9: POST-CONSTRUCTION SITE RUNOFF CONTROL PROGRAM The Town of Woodfin relies on the Buncombe County Stormwater Management Program to comply with this minimum measure. The Buncombe County Stormwater Management Program addresses stormwater runoff from new development and redevelopment projects that disturb greater than or equal to one acre, including projects less than one acre that are part of a larger common plan of development or sale, that are located within the Town of Woodfin and discharge into the MS4. These elements are designed to minimize water quality impacts utilizing a combination of structural Stormwater Control Measures (SCMs) and/or non-structural BMPs appropriate for the community and ensure adequate long-term operation and maintenance of SCMs. NCS000440 SWMP Town of Woodfin January 2021 Page 16 PART 10: POLLUTION PREVENTION AND GOOD HOUSEKEEPING PROGRAMS This SWMP provides a comprehensive pollution prevention and good housekeeping strategy for the Town of Woodfin municipal facilities and operations. Pollution prevention and good housekeeping is accomplished through the implementation of seven required programs, which collectively address the ultimate goal of preventing or reducing pollutant runoff from municipal operations such as parks and open space maintenance, fleet and building maintenance, new construction and land disturbances, and municipal storm sewer system maintenance. Pollution prevention and good housekeeping for municipal operations includes the following programs: 1. Municipal Facilities Operation and Maintenance Program 2. Spill Response Program 3. MS4 Operation and Maintenance Program 4. Municipal SCM Operation and Maintenance Program 5. Pesticide, Herbicide and Fertilizer Management Program 6. Vehicle and Equipment Maintenance Program 7.
