This SWMP identifies the specific elements and minimum measures that the Town of Weaverville 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 NCS000448 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 Weaverville and located within the corporate limits of the Town of Weaverville. In preparing this SWMP,the Town of Weaverville 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.

NCS000448 SWMP Town of Weaverville August 1,2023 Page 2 PART 3: MS4 INFORMATION 3.1 Permitted MS4 Area This SWMP applies throughout the corporate limits of the Town of Weaverville,including all regulated activities associated with the discharge of stormwater from the MS4. The map below shows the corporate limits of Town of Weaverville as of January 1, 2023. The Town of Weaverville has no authority to exercise an extraterritorial jurisdiction. Town of Weaverville-Municipal Limits(as of 1/l/2023) { :C .. . NCS000448 SWMP Town of Weaverville August 1,2023 Page 3 3.2 MS4 Mapping The Town of Weaverville is in the process of mapping its MS4 system and anticipates that the mapping will be completed prior to within permit year 1 as set out in BMP No. 21. As it develops its MS4 map,the Town will include all pipes, flow direction,inverts, ditches,inlets,catch basins,manholes,major outfalls, sizes, condition, etc., in order to conform with permit item 3.4.1 for specific requirements. It is understood that 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. Table 1: Summary of Current MS4 Mapping Percent of MS4 Area Mapped 0 % No. of Major Outfalls* Mapped 0 total 3.3 Receiving Waters The Town of Weaverville 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 Water Quality 303(d)Listed Parameter(s) Index/AU Classification of Interest Number Reems Creek 6-87- 10 C N/A Gill Branch 6-87-12 C N/A Lake Louise 6-87-11 C N/A Reynolds Branch-Tributary to C N/A the headwaters of Reems Creek Pickens Branch-Tributary from C N/A K fields Lake to Lake Louise Lyda Branch-Tributary to the C N/A headwaters of Lake Louise C—Class C (fishable/swimmable waters) NCS000448 SWMP Town of Weaverville August 1,2023 Page 4 3.4 MS4 Interconnection The Town of Weaverville MS4 is not interconnected with another regulated MS4 and directly discharges to the receiving waters as listed in Table 2 above. The MS4 does interconnect with the statewide NCDOT MS4 and includes: a. The interconnection may be receiving stormwater from the NCDOT MS4. The number of interconnections is unknown. b. The interconnection may be discharging stormwater into the NCDOT MS4. The number of interconnections is unknown. c. The Town of Weaverville MS4 mapping does not yet identify interconnections with the NCDOT MS4. d. The Town of Weaverville MS4 mapping does not include NCDOT MS4 outfalls. As a part of the MS4 mapping,the nature of the interconnection will be evaluated and documented. 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 pie. 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. Table 3: Summary of Approved TMDLs Water Body Name TMDL Pollutant(s)of Concern Stormwater Water Waste Quality Load Recovery Allocation Program Y/N Y/N Statewide Mercury N N The Statewide TMDL for mercury does not require any actions by the NPDES stormwater permittees because most mercury in stormwater comes from atmospheric deposition. NCS000448 SWMP Town of Weaverville August 1,2023 Page 5 3.6 Endangered and Threatened Species and Critical Habitat Significant populations of threatened or endangered species and/or critical habitat are identified within the regulated MS4 urbanized area, as determined by a review of the Endangered and Threatened Species and Species of Concern by County for North Carolina Map and Listed species believe to or known to occur in North Carolina map as provided by the U.S. Fish and Wildlife Service. 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 NCG030070 ABB Motors and Mechanical NCGNE0333 Shorewood Packaging Corporation NCS000448 SWMP Town of Weaverville August 1,2023 Page 6 3.8 Non-Stormwater Discharges The water quality impacts of non-stormwater discharges have been evaluated by the Town of Weaverville as summarized in Table 6 below. The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality. The Town of Weaverville has evaluated residential and charity car washing and street washing for possible significant water quality impacts. The Town does not perform street washing so street washing discharges are not relevant to the MS4. The Division has not required that other non-stormwater flows be specifically controlled by the Town of Weaverville. 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 Weaverville to determine whether they may significantly impact water quality. They were determined to be a possible cause of water quality impacts and will be addressed through public education efforts. 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 N/A Flows from firefighting activities Incidental 3.9 Target Pollutants and Sources In addition to those target pollutants identified above,the Town of Weaverville is not aware of other significant water quality issues within the permitted MS4 area. 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 NCS000448 SWMP Town of Weaverville August 1,2023 Page 7 SWMP programs that address the target pollutants. In addition,the Town of Weaverville has evaluated 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. Homeowners and businesses were identified as target audiences because they were 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. NCS000448 SWMP Town of Weaverville August 1,2023 Page 10 The stormwater activities of the Town are currently included within the general budgets of both the Public Works Department and Administration and have not been tracked. The Town recognizes that its stormwater program is currently underfunded to conduct all of the proactive elements of the permit.As the Town of Weaverville fully develops and implements its stormwater program, 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. 1 in order to fully fund the program by permit year 5. 4.3 Shared Responsibility The Town of Weaverville 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 Weaverville 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 Weaverville 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.

Pollution prevention and good housekeeping is accomplished through the implementation of seven required programs,which collectively address the ultimate goal of preventing or reducing pollutant runoff from municipal operations such as parks and open space maintenance,fleet and building maintenance,new construction and land disturbances,and municipal storm sewer system maintenance. Pollution prevention and good housekeeping for municipal operations includes the following programs: 1. Municipal Facilities Operation and Maintenance Program 2. Spill Response Program 3. MS4 Operation and Maintenance Program 4. Municipal SCM Operation and Maintenance Program 5. Pesticide,Herbicide and Fertilizer Management Program 6. Vehicle and Equipment Maintenance Program 7. Pavement Management Program Spill response procedures are currently handled by the Public Works Department. All other components of the pollution prevention and good housekeeping measures are implemented by the Public Works Department. The Town already provides limited street cleaning and seasonal leaf collection services to residents but will begin to quantify and monitor for assessment. The Town of Weaverville will manage, implement and report the pollution prevention and good housekeeping BMPs as specified in Table 21 below for each required program.
