This SWMP identifies the specific elements and minimum measures that the Town of Nashville will develop, implement, enforce, evaluate, and report to the North Carolina Department of Environmental Quality(NCDEQ)Division of Energy,Minerals and Land Resources(DEMLR)to comply with the MS4 Permit number NCS000485, as issued by NCDEQ. This permit covers activities associated with the discharge of stormwater from the MS4 as owned and operated by the T wn of Nashville and located within the corporate limits of the Town of Nashville. In preparing this SWMP,the Town of Nashville 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 ontains continue to adequately provide for permit com Nance and the community's needs. Once the SWMP is approved by NCDEQ, 11 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 pe DRAFT NCS000485 SWMP Town of Nashville November 15, 2023 Page 1 PART 2: CERTIFICATION By my signature below I hereby certify,under penalty of law,that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted.

The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality. Street washing discharges area dressed under the Pavement Management Program in Part 10 of this SWMP. Street cleaning is performed with a vacuum street sweeping process that removes excess debris/sediment/solids and reduces pollutants associated with street washing. The Division has not required that other non-stormwater flows be specifically controlled by the Town of Nashville. 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 Nashville to determine whether they may significantly impact water quality. DRAFT NCS000485 SWMP Town of Nashville November 15, 2023 Page 8 Dechlorinated swimming pool discharges are considered possible non-stormwater discharges. Therefore, the Town utilizes Public Education and Outreach BMPs 5-8 to educate businesses and residents about these potential water quality impacts. Debris collected in the town's street sweeper are disposed of as municipal solid waste at the City of Rocky Mount transfer station. Street washing discharges are addressed under BMP 38 as part of the Pavement Management Program in Part 10 of this SWMP.

Table 7 below summarizes the water quality pollutants identified throughout Part 3 of this SWMP,the likely activities/sources/targeted audiences attributed to each pollutant and identifies the associated SWMP program(s)that address each. In addition,the Town of Nashville has evaluated schools, homeowners and businesses as target audiences that are likely to have significant stormwater impacts. Target pollutants include excess nutrients and fecal coliform from pet waste,lawn and garden fertilizers, and septic system leakage.
