This SWMP identifies the specific elements and minimum measures that the City of Wilmington 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 NCS000406, 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 Wilmington and located within the corporate limits of the City of Wilmington. In preparing this SWMP, the City of Wilmington 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. *In the last year and a half, the City's Stormwater Services initiated a review of its MS4 program to achieve the following goals: 1. Prepare the City for the future DEQ audit and in understanding potential compliance issues (i.e., become "audit ready"), 2. Prepare for the re -permitting of the program and support development of what is needed for this SWMP submittal, pursuant to the reformatted version by DEQ and new permit requirements, and 3. Identify areas where improvements can be made to enhance program implementation. Using the information gathered during the review through site visits, interviews, and program documentation, the City's consultant developed a report that summarizes the program elements (6Minimum Measures) and documents how the City is meeting its permit requirements. A series of recommendations were developed for each permit area to address any potential issues or gaps with compliance as well as overall program enhancement and audit preparation. Each recommendation is accompanied by an assessment of priority status, a qualitative assessment of budget implications, and a recommended implementation schedule.

Table 1: Summary of Current MS4 Mapping Percent of MS4 Area Mapped 97.5* % No. of Major Outfalls** Mapped 135 total *The 2.5% unmapped consists of a large, newly annexed area that is currently being developed and under construction. Mapping will be updated as sections are completed and then finalized after being built out in the next several years. **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 City of Wilmington MS4 is located within the Cape Fear and White Oak River Basins and discharges directly into receiving waters as listed in Table 2 below.

The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality. The City of Wilmington 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 City of Wilmington to determine whether they may significantly impact water quality. These types of discharges have been determined to possibly impact DRAFT NCS000406 SWMP City of Wilmington, NC August 4, 2022 Page 7 water quality and are addressed by both our educational program and by our Stormwater Compliance Officers. (BMP No. 5.2 School Programs, 5.3 Community Events, 7.2 Regulatory Mechanism). Street washing procedures produce no runoff from its operation. City sweepers utilize dry and misting practices only. The misting of the roads just ahead of the sweeper brushes help to reduce dust and also reduces friction on the steel brushes. 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 City of Wilmington 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 Incidental Flows from firefighting activities Incidental 3.9 Target Pollutants and Sources In addition to those target pollutants identified above, the MS4name is aware of other significant water quality issues within the permitted MS4 area. UNC-Wilmington has contracted with the City of Wilmington to monitor surface water quality of creeks within the city limits since 1998. Based on this historical water quality monitoring data, fecal coliform has been identified as a pollutant of concern for several creeks within the city limits. Bacterial pollution has closed several creeks to commercial shellfish harvest. Fecal coliform bacterial pollution can come from uncollected pet waste, homeless encampments, wildlife/waterfowl, and episodic sewer spills. Our program focuses education primarily on pet owners and pet waste, as this is a source of pollution that can be more easily controlled Active septic systems are not an issue inside the city limits since DRAFT NCS000406 SWMP City of Wilmington, NC August 4, 2022 Page 8 homes/businesses are serviced by the sanitary sewer system operated by the Cape Fear Public Utility Authority. In addition, bacterial pollution attributed to wildlife and waterfowl is not a source that can be easily managed; however, the City and Cape Fear River Watch make efforts to educate the public about not feeding wildlife/waterfowl, particularly at Greenfield Lake. Feeding wildlife habituates them to stay in a localized area if there is a regular source of external food, adding both bacteria and nutrients to a waterbody. The City of Wilmington City Council approved the voluntary `Bradley and Hewletts Creeks Watershed Restoration Plan" in September 2012, which focuses on reducing the volume of stormwater that can transport fecal coliform to Bradley Creek & Hewletts Creek. This program is branded as the "Heal Our Waterways" (HOW) Program. The metric used to reduce this pollutant of concern is the volume of stormwater reduced, with the goal of reaching the 2006 hydrograph levels for each creek. The program is voluntary and targets property owners within the Bradley and Hewletts Creeks Watersheds to install SCMs that achieve volume reduction. There is dedicated annual funding in the Stormwater Services budget to help private property owners fund SCM installations on their properties. In addition, litter is noted as a pervasive source of stormwater pollution in local watersheds based on the amount of litter collected during volunteer cleanups, as well as during stormwater maintenance activities. Our program also educates the community about other pollutants including nutrients, yard waste, sediment, and chemical pollution/HHW, and illicit discharges. 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 Wilmington has determined the target audiences, sources, messages and outreach techniques for each noted pollutant that are likely to have significant stormwater impacts. A comprehensive description is included in our Outreach/Education & Participation/Involvement Plan. Education about these target pollutants is also included in school curriculum for New Hanover County Schools 8' grade science classes, in mass media campaigns, on our stormwater website, in print collateral, and more. The HOW Program also focuses on educating watershed residents and property owners within the Bradley and Hewletts Creeks Watersheds. SCM/BMP installations on these properties are vital to reducing the volume of stormwater transporting fecal coliform and other stormwater pollutants to these specific creeks. Finally, our Compliance Officers devote a significant amount of time on public education and outreach to address documented incidents and prevent future/potential incidents of stormwater pollution in the community.

The target audiences and identified pollutants listed in Part 3.9 of this SWMP, which will be addressed by the Public Education and Outreach Program, are summarized in Table 12 below. In addition, the City of Wilmington is required to inform businesses and the general public of the hazards associated with illicit discharges, illegal dumping and improper disposal of waste. The city's outreach/education and participation goals can be summarized by the following: • Raise awareness and educate the community about the impacts of polluted stormwater runoff on local waterways, including simple and attainable solutions to stormwater pollution • Promote ongoing citizen participation/involvement by including the public in community activities aimed at cleaning up, reducing, and preventing stormwater pollution. Two outside agency service contracts with Cape Fear River Watch and New Hanover Soil & Water Conservation District enable the city to meet and exceed permit requirements and bolster our reach and impact in the community. These contracts focus on outreach/education and involvement/participation activities and can be viewed in the Appendix. The legal service contracts generally align with the timeframe of our stormwater permit 5-year timeframe. (*Please Note: These contracts will be re- negotiated at the start of our new permit and fiscal year in July 2023. This will begin the new 5-year contract terms which may differ from what is included in this draft SWMP).
