This SWMP identifies the specific elements and minimum measures that the City of Statesville 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 NCS000587, as issued by NCDEQ. This permit covers activities associated with the discharge of stormwater from the MS4 as owned and operated by the City of Statesville and located within the corporate limits of the City of Statesville. In preparing this SWMP,the City of Statesville 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. Any major changes to the approved SWMP will require resubmittal, review and approval by NCDEQ, and may require a new public comment period depending on the nature of the changes.

Steele&Sons,Inc. 3.8 Non-Stormwater Discharges The water quality impacts of non-stormwater discharges have been evaluated by the City of Statesville as summarized in Table 6 below. The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality. The City of Statesville has evaluated residential and charity car washing and street washing for possible significant water quality impacts. Street cleaning is performed with a dry sweeping process; street washing discharges are not relevant to the MS4. NCS000587 SWMP City of Statesville February 2023 Page 6 The Division has not required that other non-stormwater flows be specifically controlled by the City of Statesville. 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 City of Statesville to determine whether they may significantly impact water quality. They were determined to be a possible cause of water quality impacts and will be addressed through public education efforts. Table 6: 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 Foundation drains Incidental Air conditioning condensate Incidental Irrigation waters Incidental Springs Incidental Water from crawls ace 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 N/A Flows from firefighting activities Incidental 3.9 Target Pollutants and Sources In addition to those target pollutants identified above,the City of Statesville is not aware of other significant water quality issues within the permitted MS4 area. 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 City of Statesville has evaluated schools, homeowners and businesses as target audiences that are likely to have significant stormwater impacts. Selecting schools as a target audience provides the opportunity to reach many families and have a significant impact through education and outreach opportunities. Selecting homeowners and businesses as NCS000587 SWMP City of Statesville February 2023 Page 7 target audiences provides the opportunity to impact non-point pollution by citizens and businesses that are polluting unintentionally through uninformed management practices.

The budget includes the permit administering and compliance fee,which is billed by the Division annually. The City of Statesville Council adopted the Stormwater Utility Ordinance on_May 6,2019,creating a public enterprise,referred to as the Statesville Stormwater Utility,for the purpose of generating revenue to support the Statesville Stormwater Management Program. The fee is based on an Equivalent Residential Unit(ERU)that was estimated based on measured impervious area of a sample of residential properties across the City. Each single-family residential property with built upon area will be billed the established fee for 1 ERU,currently$4.70,per month. Each non-single-family residential property will be billed 1 ERU per 3,050 square feet of impervious area per month. The utility began billing in July 2019. Total ERUs for the City were estimated and the stormwater fee was set to generate an estimated revenue of$2 million per year. This budget includes approximately$300,000 for stormwater professional staff, $300,000 for additional maintenance staff, $600,000 in annual capital projects, $125,000 in NPDES program efforts,and$675,000 surplus to carry over. 4.3 Shared Responsibility The City of Statesville 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 City of Statesville remains responsible for compliance if the other entity fails to perform the permit obligation and may be subject to enforcement action if neither the City of Statesville nor the other entity fully performs the permit obligation.
