This SWMP identifies the specific elements and minimum measures that the Town of Lewisville 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 NCS000494, 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 Lewisville and located within the corporate limits of the Town of Lewisville. In preparing this SWMP, the Town of Lewisville 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 pen -nit 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 MS4 area was mapped in 2012 and is being updated in 2020 to include previously unmapped areas. Stoi-inwater inflows include information on material, diameter/box size, depth, and ground cover. Culvert drain pipes include information on diameter, box size, material, ground cover, and length. Stormwater discharges include information on material, diameter/box size, ground cover, and receiving stream. The stormwater discharges mapped include outfalls, but specific classification of major outfalls versus all other points of discharge has not occurred.

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 Lewisville MS4 is located within the Yadkin -Pee Dee 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 Yadkin River 12-(80.7) WS-Iv Fecal Coliform (recreation) Mill Creek 12-82 WS-IV None listed Shallow Ford Lakes 12-82-1 WS-IV None listed Panther Creek 12-87-(0.4) C None listed Double Creek 12-87-1-(0.4) C None Iisted BIacks Creek 12-87-1-1 WS-1V None listed Ellison Creek 12-88-(0.4) C None listed EIlison Creek 12-88-(0.7) WS-IV None listed Blanket Creek 12-90-(1) C None listed Reynolds Creek 12-94-9 C Ecological/biological integrity benthos 3.4 MS4 Interconnection The Town of Lewisville MS4 is not interconnected with another regulated MS4 and directly discharges to the receiving waters as listed in Table 2 above. DRAFT NCS000494 SWMP Town of Lewisville January 1, 2021 Page 5 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 page. 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.

The Town of Lewisville has applied for No Exposure Certification for their Public Works facility. DRAFT NCS000494 SWMP Town of Lewisville January 1, 2021 Page 6 Table 5: NPDES Stormwater Permitted Industrial Facilities Permit Number Facility Name NIA 3.8 Non-Stormwater Discharges The water quality impacts of non-stormwater discharges have been evaluated by the Town of Lewisville as summarized in Table 6 below. The unpermitted non-stonnwater flows listed as incidental do not significantly impact water quality. The Town of Lewisville 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 Lewisville. 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 Lewisville to deterraine whether they may significantly impact water quality.

However, the Town has identified other pollutants it will address including litter, yard waste, pet waste, and sediment. These determinations have been made due to citizen complaints, employee investigations, citizen complaints, County inspections, and State water quality testing. 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 Town of Lewisville has evaluated schools, homeowners and businesses as target audiences that are likely to have significant stormwater impacts.

The fiscal year budget below demonstrates the allocation to Stormwater activities for 2019-2020, although salaries for stormwater staff are funded through the Public Works department. The fiscal analysis completed for 2017 showed a need to increase the stormwater funding which was approved for each year since 2017.
