This SWMP identifies the specific elements and minimum measures that the Town of Black Mountain 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 NCS000422, 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 Black Mountain and located within the corporate limits of the Town of Black Mountain. In preparing this SWMP, the Town of Black Mountain 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. NCS000422 SWMP Town of Black Mountain November 2021 Page 3 PART 3: MS4 INFORMATION 3.1 Permitted MS4 Area This SWMP applies throughout the corporate limits of the Town of Black Mountain, including all regulated activities associated with the discharge of stormwater from the MS4.

The budget includes the permit administering and compliance fee, which is billed by the Division annually. The funding for the stormwater program comes exclusively from fund balance; however, the town is formally exploring establishing a stormwater utility. The town also seeks grants for projects to improve stormwater quality and reduce stormwater quantity as they become available. The town acknowledges the lack of appropriate funding and is committed to finding ways to increase program funding. These grants are used for typically used for SCM installation and stream restoration projects. Not all of these projects are directly related to NPDES compliance, however, do hold benefit to the watershed in general. The town has completed a stormwater utility study. The Town Council will consider the proposal for adoption and implementation in FY 21-22. Projected revenue will vary on adopted rate structure, but could be approximately $350,000 per year. Currently the town funds staff positions of which a percentage of their work is related to stormwater. A conservative estimates of these percentages are: Public works crews $56,000 Public Works Director $15,000 Town Manager $20,000 Planning Director $15,000 Building Inspector $8,000 Total $114,000 4.3 Shared Responsibility The Town of Black Mountain will share the responsibility to implement the following minimum control measures, which are at least as stringent as the corresponding NPDES MS4 Permit NCS000422 SWMP Town of Black Mountain November 2021 Page 15 requirement. The Town of Black Mountain 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 Black Mountain 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.
