This SWMP identifies the specific elements and minimum measures that the City of Lexington 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 NCS000584, as issued by NCDEQ. This permit covers activities associated with the discharge of stormwater from the MS4 as owned and operated by the City of Lexington and located within the corporate limits of the City of Lexington. In preparing this SWMP, the City of Lexington 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.

When known, attributes such as material, size, elevation, ownership, etc., are included in the features' attribute tables. The entire MS4 area has not been mapped, however, a grid system is currently being used to identify and inventory the missing areas. An MS4 GIS map is available to the public on ArcGIS Online. The direct link to this map is https•//www arcgis com/apps/webappviewer/index html?id=elb3340c280a4efd9bb7cf7d8d53c76f. There is also a stormwater database for internal use in ArcGIS.

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. "For the outfalls that have been mapped, the classification as a Major Outfall has not been used. However, there are 137 known outfalls with a pipe diameter ofat least 36 inches. 3.3 Receiving Waters The City of Lexington MS4 is located within the Yadkin Pee -Dee River Basin and discharges directly into receiving waters as listed in Table 2 below.

The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality. The City of Lexington has evaluated residential and charity car washing for possible significant water quality impacts. Street cleaning is performed with a dry street sweeping process 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 City of Lexington. 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 City of Lexington 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 (See BMP Nos. 8 and 9).

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 City of Lexington has evaluated schools, homeowners and businesses as target audiences that are likely to have significant stormwater impacts. Residents, businesses, schools, and municipal staff have been evaluated as likely sources and target audiences for the pollutants mentioned below because of the possibility that proper best management practices are not being followed to prevent potential pollution. Schools are also an important target audience because of the opportunity to educate students about stormwater pollution prevention.

The budget includes the permit administering and compliance fee, which is billed by the Division annually. For Fiscal Year 2019/2020, the stonnwater budget was approximately $50,000, funded in combination by the Water Resources Department and the General Fund. Beginning in February 2021, a monthly stonnwater utility fee will be assessed to all properties within the city limits with an impervious surface area equal to or greater than 400 112. Single-family residential properties will be assessed a fee of $3.50 on the monthly utility bill. Non -single-family residential, commercial, and industrial properties will be assessed a monthly fee on the utility bill based on the amount of impervious surface area on the property. These properties will be assessed $3.50 per Equivalent Residential Unit (ERU), which is equal to 2,700 ft2 in Lexington. Approximately $745,000 has been budgeted for operational costs for Fiscal Year 2020/2021. 4.3 Shared Responsibility The City of Lexington 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 City of Lexington remains responsible for compliance if the other entity fails to perform the permit obligation, and may be subject to enforcement action if neither the City of Lexington 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.

DRAFT NCS000584 SWMP City of Lexington December 4, 2020 Page 34 PART 10: POLLUTION PREVENTION AND GOOD HOUSEKEEPING PROGRAMS This SWMP provides a comprehensive pollution prevention and good housekeeping strategy for the City of Lexington municipal facilities and operations. 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 The City of Lexington will manage, implement and report the pollution prevention and good housekeeping BMPs as specified in Table 21 below for each required program. Table 21: Pollution Prevention and Good Housekeeping BMPs Permit 3.7.1: Municipal Facilities Operation and Maintenance Program Ref.
