This SWMP identifies the specific elements and minimum measures that the Town of Clayton 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 NCS000559, 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 Clayton and located within the corporate limits and ETJ of the Town of Clayton. In preparing this SWMP, the Town of Clayton 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 six minimum measures the Town is required to address are the following: • Public Education and Outreach • Public Involvement and Participation • Illicit Discharge Detection and Elimination (IDDE) • Construction Site Runoff Controls • Post -Construction Runoff Controls • Pollution Prevention and Good Housekeeping for Municipal Operations DRAFT NCS000559 SWMP Town of Clayton August 2022 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.

DRAFT NCS000559 SWMP Town of Clayton August 2022 Page 2 PART 3: MS4 INFORMATION 3.1 Permitted MS4 Area This SWMP, and the MS4 permit, applies throughout the corporate limits and the ETJ (extra -territorial jurisdiction) of the Town of Clayton, including all regulated activities associated with the discharge of stormwater from the MS4. As of July 2022, the Town's current corporate area is 16.08 square miles; the Town's ETJ and zoning jurisdictional area is 46.33 square miles. The Town's corporate limits and ETJ are located within Johnston County, with a small portion located in Wake County. The following map (Figure 1) shows the corporate limits and the ETJ of the Town of Clayton as of July 2022. Additionally, this map is updated regularly and can viewed on the Town's GIS webpaEe. Figure 1: Town of Clayton Corporate Limits and ED as of July 2022 DRAFT NCS000559 SWMP Town of Clayton August 2022 Page 3 3.2 Existing MS4 Mapping The current MS4 mapping consists of both closed channel and open channel vegetive conveyance. Stormwater is conveyed through a combination of pipes, curbs, gutters, ditches, swales, drop inlets, catch basins, culverts, outfalls, bridges, and overland sheet flow. Additionally, the MS4 mapping includes an inventory of both public and privately maintained stormwater control measures (SCMs). For most of the MS4 mapped drainage features, identifying information such as type of material, pipe diameter, culvert dimensions, and inverts is included. The SCMs include the type and location, and when available, reference to the recorded Operation and Maintenance (O&M) Manual. To adequately prepare for Capital Improvement Program (CIP) needs as well as ensure the safety and well-being of the residents within the Town's corporate limits and ETJ and our down -stream community neighbors, the Town has identified finalizing GIS mapping of the Town's stormwater system and developing a Town wide Stormwater Master Plan as major priorities within the next five (5) years. The Town's MS4 GIS map can be found here. Table 1: Summary of MS4 Mapping (as of 2021 annual report) Percent of MS4 Area Mapped 65 No. of Major Outfalls* Mapped 193 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 receiving waters within the Town of Clayton corporate limits and ETJ are located solely within the Neuse River Basin. Table 2, listed below, identifies an inventory of receiving streams within the MS4 area. The stream index number, water quality classification, and 303(d) list of parameters of interest are noted in Table 2. 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 DRAFT NCS000559 SWMP Town of Clayton August 2022 Page 4 Table 2: Summary of MS4 Receiving Waters Receiving Water Name Stream Index / AU Number Water Quality Classification 303(d) Listed Parameter(s) of Interest Big Arm Creek 27-38-1 C; NSW n/a Little Creek 27-43-12 C; NSW Benthos (Nar, AL, FW) Marks Creek 27-38 C; NSW n/a Neuse River 27-(36) 1 WS-V; NSW I Copper (7ug/I, AL, FW); Zinc (50ug/I, AL, FW) Neuse River 27-(38.5) 1 WS-IV; NSW I n/a 3.4 MS4 Interconnection The Town of Clayton MS4 is not interconnected with another regulated MS4 and directly discharges to the receiving waters as listed in Table 2 above. The MS4 does interconnect with NCDOT's statewide TS4 and includes the following: 1. The interconnection is receiving stormwater from the NCDOT TS4. The number of interconnections was not able to be determined using the data that is currently available. 2. The interconnection is discharging stormwater into the NCDOT TS4. The number of interconnections was not able to be determined using the data that is currently available. 3.5 Total Maximum Daily Loads (TMDLs) The TMDLs) 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.

The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality. DRAFT NCS000559 SWMP Town of Clayton August 2022 Page 6 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 Clayton. Wash water associated with car washing that does not contain detergents or does not discharge directly into the MS4 is considered incidental. Residential and non-profit car washing is exempt from the Town's IDDE ordinance. However, these types of non-stormwater discharges that do contain detergents have been evaluated by the Town of Clayton to determine whether they may significantly impact water quality. It has been determined by the Town of Clayton that residential and non-profit car washing may impact water quality, but they occur infrequently enough it does not need to be limited at this time. This SWMP addresses measures taken by the Town of Clayton to reduce the target pollutants of wash water associated with residential and non-profit car washing. 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 Clayton 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 DRAFT NCS000559 SWMP Town of Clayton August 2022 Page 7 SWMP program(s) that address each.

The budget includes the permit administering and compliance fee, which is billed by the Division annually. The Stormwater Program currently receives funding of approximately $ 500,000 per year; funded through the Town's General Fund. The program has 12 staffed members; 2 full-time stormwater staff and 10 full-time auxiliary staff to provide program support. The Town's MS4 program has recently become administered by Town staff and is still being fully developed. The program is currently under -funded and under -staffed to conduct all the proactive elements of the permit. Further fiscal analysis and investigation will be conducted to further evaluate staff and funding needs. Additionally funding sources, such as a Stormwater Utility Fee, may also be evaluated to reduce the gap in available funding. 4.3 Shared Responsibility The Town of Clayton 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 Clayton 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 Clayton 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.
