This SWMP identifies the specific elements and minimum measures that the Town of Swepsonville 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 NCS000405 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 Swepsonville and located within the corporate limits of the Town of Swepsonville. In preparing this current SWMP,the Town of Swepsonville has evaluated its MS4,the permit requirements of it's MS4, and previous Comprehensive Stormwater Management Plans 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.

Major outfalls are required to be mapped to meet permit requirements. A major outfall is a 36-inch diameter pipe or discharge from a drainage area> 50-acres; and for industrial zoned areas a 12-inch diameter pipe or a drainage area> 2-acres. **Swepsonville's entire stormwater system is mapped currently but due to growth this is an ongoing task 3.3 Receiving Waters The Town of Swepsonville MS4 is located within the Cape Fear 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 Water 303(d)Listed Parameter(s) /AU Number Quality of Interest Classification Haw River 16- 10.5 WS-V;NSW Turbidity, Fecal Coliform 16-(1)e WS-V;NSW Unnamed Tributary to Haw River.

NCS000405 SWMP October 9, 2023 Town of Swepsonville Page 4 3.4 MS4 Interconnection The Town of Swepsonville's MS4 is interconnected with the NCDOT MS4 within NCDOT owned right of ways. 3.5 Total Maximum Daily Loads (TMDLs) The TMDL(s)listed in Table 3 below have been approved within the MS4 area, as determined by the map and list provided on the NCDEQ Modeling&Assessment Unit web page. The table also indicates whether the approved TMDL has a specific stormwater Waste Load Allocation(WLA) for any watershed directly receiving discharges from the permitted MS4, and whether a Water Quality Recovery Program has been implemented to address the WLA. Table 3: Summary of Approved TMDLs Water Body Name TMDL Pollutant(s)of Concern Stormwater Water Waste Quality Load Recovery Allocation Program Y/N Y/N Haw River Turbidity,Fecal Coliform N N The Jordan Lake TMDL is the subject of extensive rulemaking,of which the Town of Swepsonville is not included. NCS000405 SWMP October 9, 2023 Town of Swepsonville Page 5 3.6 Endangered and Threatened Species and Critical Habitat Significant populations of threatened or endangered species and/or critical habitat are not identified within the regulated MS4 urbanized area. Based upon a review of the Endangered and Threatened Species and Species of Concern by County for North Carolina Map and Listed species believe to or known to occur in North Carolina map as provided by the U.S. Fish and Wildlife Service,the species listed in Table 4 have the potential to occur within the regulated MS4 urbanized area. Of those species listed, Table 4 summarizes the species that may be significantly impacted by the quality of surface waters within their habitat.

Table 5: NPDES Stormwater Permitted Industrial Facilities Permit Number Facility Name NONE 3.8 Non-Stormwater Discharges The water quality impacts of non-stormwater discharges have been evaluated by the Town of Swepsonville as summarized in Table 6 below. The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality. The Town of Swepsonville 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 Swepsonville. 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 Swepsonville to determine whether they may significantly impact water quality. Currently runoff from car washing in The Town of Swepsonville would be considered incidental.

The education program will target total suspended solids and nutrient loading because turbidity, sedimentation, and nutrients are the pollutants of concern in downstream waters. In addition, floatables, trash,and debris will also be targeted. The education program will also address the proper use and disposal of typical household chemicals, garden chemicals,and used motor oil. 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 Swepsonville has evaluated schools, homeowners and businesses as target audiences that are likely to have significant stormwater impacts.

NCS000405 SWMP October 9, 2023 Town of Swepsonville Page 21 PART 9: POST-CONSTRUCTION SITE RUNOFF CONTROL PROGRAM The Town of Swepsonville operates a Post Construction Site Runoff Control Program that regulates 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 Swepsonville 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. The Town's post construction ordinance is contained in Section 1 of its Code of Ordinances. The Town maintains a stormwater design manual that is deemed equal or more stringent than the NC DEQ BMP Manual. The annual reporting metrics for the post construction program are provided in Table 20: Post Construction Site Runoff Control BMPs below.
