This SWMP identifies the specific elements and minimum measures that the Town of Carolina Beach 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 NCS000394, 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 Carolina Beach and located within the corporate limits of the Town of Carolina Beach. In preparing this SWMP, the Town of Carolina Beach 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.

Applicable water quality standards listed below are compiled from the following NCDEQ sources: o Waterbodv Classification Map o Impaired Waters Map o Most recent NCDEQ Final 303(d) List Table 2: Summary of MS4 Receiving Waters Receiving Water Name Stream Index / Water Quality 303(d) Listed Parameter(s) AU Number Classification of Interest Carolina Beach Yacht Basin 18-87-31.2 SB Fish Tissue Mercury (NAR,FC, NC) Cape Fear River 18-(71)b SC pH (8.5, AL, SW) Atlantic Ocean (Emergency 99-(3)c SB Fish Tissue Mercury (NAR, Discharge Option) I FC, NC) SB - Primary recreation, saltwater SC - Aquatic life, saltwater Fish Tissue Mercury (NAR, FC, NC) - Narrative standard, fish consumption advisory, North Carolina standard pH (8.5, AL, SW) - Aquatic life impairment, saltwater The above Data is from 2022 NC Category 5 Assessments "2022 Final 303(d) List" and NC Surface Water Classifications Map. From the 2022 303(d) Listing and Delisting Methodology for fish Consumption: "Fish consumption was assessed based on site-specific fish consumption advisories developed using fish tissue data. Advisories and advice are developed by DHHS using fish tissue data collected by DWR and others. See http://epi.publichealth.nc.gov/fish/current.html for all advice and advisories." The Town of Carolina Beach utilizes Public Education and Outreach BMPs 5-8 to provide information on water quality impairments in the Cape Fear River Basin. AS4 Interconnection The Town of Carolina Beach MS4 is interconnected with another regulated MS4 and directly discharges stormwater into the Town of Kure Beach MS4 during emergency overflow situations. The number of interconnections leaving the Town of Carolina Beach MS4 to the Town of Kure Beach is one. The MS4 does not interconnect with the statewide NCDOT MS4. NCS000394 SWMP Town of Carolina Beach August 2, 2023 Page 5 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. Currently there are no approved TMDLs within the MS4 area. Table 3: Summary of Approved TMDLs TMDL Pollutant(s) of Stormwater Water Quality Water Body Name Concern Waste Load Recovery Allocation (Y/N) Program (Y/N) Statewide Mercury N N The Statewide TMDL for mercury does not require any actions by the NPDES Stormwater Permittee because most mercury in stormwater comes from atmospheric deposition, but the Town utilizes BMPs 5-8 to provide information on water quality impairments in the Cape Fear River Basin. 3.6 Endangered and Threatened Species and Critical Habitat Significant populations of threatened or endangered species and/or critical habitat may be 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 (no longer available online) and Listed species believe to or known to occur in North Carolina list 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 NCG190099 Carolina Beach Marina, LLC NCGNE0638 Joyner Marina, LLC NCGNE0668 Carolina Beach WWTP NCGNE0891 Town of Carolina Beach Town Marina 3.8 Non-Stormwater Discharges The water quality impacts of non-stormwater discharges have been evaluated by the Town of Carolina Beach as summarized in Table 6 below. The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality. The Town of Carolina Beach has evaluated residential and charity car washing and street washing for possible significant water quality impacts. 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 Carolina Beach to determine whether they may significantly impact water quality. The Town has determined that it is unlikely that car washing discharges will enter the MS4 as there is minimal curb and gutter throughout the Town unless it is on a DOT road. Therefore, all car washing is considered incidental. Dechlorinated swimming pool discharges have been evaluated by the Town and are considered possible non-stormwater discharges.Therefore,the Town utilizes Public Education and Outreach BMPs 5-8 to educate residents and businesses about these potential water quality impacts. NCS000394 SWMP Town of Carolina Beach August 2, 2023 Page 7 Materials collected in the Town's wet street sweeper are disposed of at the waste treatment plant. 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 Carolina Beach has evaluated 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 leakages.
