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.

The map below shows the corporate limits of Town of Black Mountain as of the date of this document. 3.2 Existing MS4 Mapping The current MS4 mapping includes inlets, outfalls and stormwater pipes. Some details are available for each location within the mapping tool, such as basic assessment of condition, size and photo. http://bmt.maps.arcgis.com/apps/webappviewer/index.html?id=b71b29247aa14a47a8a8a64c49de0dc0 Table 1: Summary of MS4 Mapping Percent of MS4 Area Mapped unknown % No. of Major Outfalls* Mapped 138 total NCS000422 SWMP Town of Black Mountain August 2019 Page 4 *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 Town of Black Mountain MS4 is located within the French Broad River Basin and discharges directly into receiving waters as listed in Table 2 below. 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 Table 2: Summary of MS4 Receiving Waters Receiving Water Name Stream Index / AU Number Water Quality Classification 303(d) Listed Parameter(s) of Interest Unnamed tributaries to Swannanoa River Unnamed tributaries to North Fork and South Fork Swannanoa River 6-78 C Benthos (Nar, AL, FW) Tomahawk Branch 6-78-9 B Unnamed tributaries to Tomahawk Branch Bryar Branch 6-78-10-4 B Wolfpit Branch 6-78-10-(2) C Laurel Branch 6-78-8-(2) B, Tr Camp Branch 6-78-7 C Unnamed tributary to Camp Branch Lynch Creek 6-78-7-2 Britton Creek 6-78-7-1 C Flat Creek 6-78-6-(4) C Unnamed tributary to Flat Creek McCoy Cove C – Class C (fishable/swimmable waters)WS III/IV/V – Water Source Benthos (Nar, AL, FW) – Narrative standard, aquatic life, fresh waters.

NCG140166 Southern Concrete Mat-Buncombe NCG020150 Grove Stone & Sand Company NCS000422 Black Mountain town - Small MS4 3.8 Non-Stormwater Discharges The water quality impacts of non-stormwater discharges have been evaluated by the Town of Black Mountain as summarized in Table 6 below. The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality. The Town of Black Mountain has evaluated residential and charity car washing and street washing for possible significant water quality impacts. 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 Black Mountain. 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 Black Mountain to determine whether they may significantly impact water quality.

NCS000422 SWMP Town of Black Mountain August 2019 Page 13 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 the general fund, however, the town is formally exploring establishing a stromwater 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 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. Currently the town funds staff positions of which a percentage of their work is related to the stormwater program, however these percetnages have not been tracked and are currently undefined. These staff positions include public work crew, public works director, planning director, planner, building inspector and town manager. The program is currently under-funded and cannot 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 three. 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 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.
