This SWMP identifies the specific elements and minimum measures that the Town of Navassa 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 NCS000518, 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 Navassa and located within the corporate limits of the Town of Navassa. In preparing this SWMP, the Town of Navassa 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 unpennitted non-stonnwater flows listed as incidental do not significantly impact water quality. The Town of Navassa has evaluated residential and charity car washing and street washing for possible significant water quality impacts. The Division has not required that other non-stormwater flows be specifically controlled by the Town of Navassa. 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 Navassa to determine whether they will significantly impact water quality. They were determined to be a possible cause of water quality impacts in more densely populated neighborhoods and will be addressed through public education efforts.

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 programs that address each. In addition, the Town of Navassa has evaluated proposed schools, homeowners and businesses as target audiences that are likely to have significant stormwater impacts. The schools were selected as a target audience due to the opportunity to affect positive change through education and involvement opportunities in a younger demographic. With the intent to start positive habits that support sustainable behaviors such as anti -littering or interaction with local waterways. Homeowners and businesses were identified as target audiences because they are likely sources of non - point pollution through uninformed management practices.

The budget includes the permit administering and compliance fee, which is billed by the Division annually. The stormwater program currently receives funding of approximately $10,000 per year; this is funded primarily through the General Fund. However, the Planning Director and Public Works employee positions are funded through the General Fund and Powell Bill respectively. In total the program receives 2 full-time equivalent staff for pavement management (1 full time Stormwater Administrator and 1 full time Stormwater Inspector). The program is currently under -funded to conduct all the proactive elements of the permit. Further fiscal analysis and investigation of funding options (such as additional general fund allocation or a stormwater fee) will be conducted as indicated in BMP No. 3 in order to fully fund the program by Permit year two. 4.3 Shared Responsibility The Town of Navassa 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 Navassa remains responsible for compliance if the other entity fails to perform the permit obligation, and will be subject to enforcement action if neither the Town of Navassa 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.
