This SWMP identifies the specific elements and minimum measures that the Town of Ayden 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 NCS000500, 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 Ayden and located within the corporate limits of the Town of Ayden. In preparing this SWMP, the Town of Ayden 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.

The map below shows the corporate limits of Town of Ayden as of the date of this document. 3.2 Existing MS4 Mapping The Town of Ayden maintains a Geographic Information System (GIS) database that includes detailed geospatial information related to the Town’s storm sewer conveyance system. The database also includes geospatial information related to drainage areas, receiving streams, land use, zoning, floodplain data, and other pertinent data. This information is updated periodically. Pursuant to the Town of Ayden’s current permit, components of their MS4 were mapped using Global Positioning System (GPS) technology and are included in the GIS. The Town will update the GIS Stormwater Layer to reflect changes to the MS4 as necessary. This may include updating stormwater system components for new development, repairs, and maintenance, in addition to updating stream data based on surface water identification requests. Mapping updates of the MS4 is solely the Town’s responsibility. NCS000500 SWMP Town of Ayden June 25, 2021 Page 5 Table 1: Summary of MS4 Mapping Percent of MS4 Area Mapped 60 % No. of Major Outfalls* Mapped 1 total *An outfall is a point where the MS4 discharges from a pipe or other conveyance (e.g. a ditch) directly into surface waters. 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. 3.3 Receiving Waters The Town of Ayden MS4 is located within the Neuse 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 1 - Swift Creek 27-97-(0.5) C; Sw; NSW Poor bioclassification, benthos (Nar, AL, FW) 2 - UT to Swift Creek C; Sw; NSW 3 - UT to Swift Creek C; Sw; NSW 4 - UT to Swift Creek C; Sw; NSW 5 - UT to Swift Creek C; Sw; NSW 6 - UT to Contentnea Creek C; Sw; NSW Maps: Primary Receiving Streams NCS000500 SWMP Town of Ayden June 25, 2021 Page 6 Receiving Stream 1 – Swift Creek Receiving Stream 2 – UT to Swift Creek Receiving Stream 3 – UT to Swift Creek Receiving Stream 4 – UT to Swift Creek Receiving Stream 5 – UT to Swift Creek Receiving Stream 6 – UT to Contentnea Creek NCS000500 SWMP Town of Ayden June 25, 2021 Page 7 3.4 MS4 Interconnection The Town of Ayden MS4 is not interconnected with another regulated MS4 and directly discharges to the receiving waters as listed in Table 2 above. 3.5 Total Maximum Daily Loads (TMDLs) Currently, no streams with the Town of Ayden’s jurisdiction have an associated Total Maximum Daily Load (TMDL). Table 3: Summary of Approved TMDLs Water Body Name TMDL Pollutant(s) of Concern Stormwater Waste Load Allocation (Y/N) Water Quality Recovery Program (Y/N) None NCS000500 SWMP Town of Ayden June 25, 2021 Page 8 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, as determined by 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. 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 NCG140296* Southern Equipment Company, Inc. • Permit issued for original facility located at 6856 NC Hwy 11. Original facility closed as part of NC Department of Transportation Southwest ByPass project. Southern Equipment Company, Inc. (Snow Tractor and Equipment) is now located at 8142 NC Hwy 11 (outside of Ayden’s jurisdiction). 3.8 Non-Stormwater Discharges The water quality impacts of non-stormwater discharges have been evaluated by the Town of Ayden as summarized in Table 6 below. Non-stormwater discharges were identified based on guidance from the Department of Environmental Quality. Town staff reviewed the potential sources for a description of potential impact to water quality (results summarized in Table 6). The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality. The Town of Ayden has evaluated residential and charity car washing and street washing for possible significant water quality impacts. NCS000500 SWMP Town of Ayden June 25, 2021 Page 9 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 Ayden. 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 Ayden to determine whether they may significantly impact water quality. 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 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 3.9 Target Pollutants and Sources In addition to those target pollutants identified above, the Town of Ayden 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 Town of Ayden has evaluated schools, homeowners and businesses as target audiences that are likely to have significant stormwater impacts.
