This SWMP identifies the specific elements and minimum measures that the Town of Harrisburg 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 NCS0000513, 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 Harrisburg and located within the corporate limits of the Town of Harrisburg. In preparing this SWMP, the Town of Harrisburg 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.

Major ou falls 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 Harrisburg MS4 is located within the Yadkin-PeeDee 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 NCS0000513 SWMP Town of Harrisburg,NC April 2024 Page 4 Table 2-Summary of MS4 Receiving Waters Receiving Water Name Stream Water 303(d)Listed Parameter(s) Index/AU Quality of Interest Number Classification Mallard Creek 13-17-5b C Per Final 2022 303(d)List, listed j for Benthos(Nar,AL,FW)and Fish Community(Nar,AL,FW).

Fuda Creek 13-17-7-1 C None 3.4 MS4 Interconnection The Town of Harrisburg MS4 is not interconnected with another regulated MS4 and directly discharges to the receiving waters as listed in Table 2 above. 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. 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 McKee Creek Fecal Coliform N N NCS0000513 SWMP Town of Harrisburg,NC April 2024 Page 5 The McKee Creek and Clear Creek TMDL was developed in 2002, and approved in August 2003,prior to the issuance of an MS4 permit to the Town of Harrisburg. As such,the Town is not specifically identified as part of the waste load allocation in the TMDL. Recognizing the timing of TMDL development in 2002 and the issuance of an MS4 permit to the Town in 2005, the Town performed a risk assessment in 2012 regarding its potential contribution to the current and future waste load in the TMDL watershed. HDR Engineering, Inc of the Carolinas identified the Town having a low potential for waste load contribution since the Town has only 80 acres of jurisdiction in the watershed. Current annexation laws may limit the Town's ability to regulate development in balance of the watershed. Despite this low potential the Town developed a waste load reduction plan for the McKee Creek and Clear Creek should future development occur in the watershed. This plan focuses on working within the MS4 permit control measures to reduce fecal coliform loading. Proposed Best Management Practices (BMPs) include encouraging the use of fecal coliform reducing structural stormwater control measures (SCMs)for new development,performing public education and outreach about the TMDL to residents and business in the watershed, consideration of a pet waste ordinance or collection requirements for development common areas, and evaluation of opportunities for SCM retrofits. 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 Listed species believed to or known to occur in North Carolina 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.

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 Harrisburg. 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 Harrisburg to determine whether they may significantly impact water quality. The water quality impacts of non-stormwater discharges have been evaluated by the Town of Harrisburg. Non-stormwater discharges associated with the following activities, as specified in 40 CFR 122.26, are allowed, provided that they do not significantly impact water quality: • Other non-stormwater discharges for which a valid NPDES discharge permit has been approved and issued by the state of North Carolina, and provided that such discharges to the municipal separate storm sewer system shall be authorized by the Town. Prohibited substances include, but are not limited to, oil, anti-freeze, chemicals, animal waste, paints, garbage and litter. Illicit discharges are addressed in further detail in Part 7: Illicit Discharge Detection and Elimination Program.

These include bacteria, turbidity/metals, Phosphorous, nitrogen, organics, surfactants, hydrocarbons, and pH altering/toxic compounds. Likely sources as well as known issues contributing to these sources can be found in Table 7. Table 7 summarizes the water quality pollutants identified throughout Part 3 of this SWMP, the likely activities/sources/targeted audiences attributed to each pollutant, identifies the associated SWMP program(s)that address each, and issues contributing to the pollutant source. The Town of Harrisburg has evaluated schools, homeowners and businesses as target audiences that are likely to have significant stormwater impacts.

The budget includes the permit administering and compliance fee, which is billed by the Division annually. There are currently five positions partially funded by the Stormwater Management Program. These positions include the Engineering and Public Works Director, Engineering Manager, Engineer in Training (2), and Grading Inspector. Funding for stormwater is provided through Stormwater Fees which are assessed to commercial and residential property owners via the monthly water and sewer bill.The charge per equivalent residential unit (ERU)for FY22 is $5.62 per month. The total FY 22 annual budget (excluding capital improvement projects) for the NPDES stormwater management program is $795,992. The Town's current stormwater utility is calculated using impervious area based on as-builts and a residential equivalent unit. 4.3 Shared Responsibility The Town of Harrisburg shares the responsibility to implement the Construction Site Runoff Control and Public Education and Outreach minimum control measures. The Town of Harrisburg 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 Harrisburg nor the other entity fully performs the permit obligation. Table 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 a legal agreement to share responsibility is in place. NCS0000513 SWMP Town of Harrisburg,NC April 2024 Page 14 The Town relies on the Mooresville Regional office of the NCDEQ to provide erosion control and sedimentation review and inspection services, consistent with the Sedimentation Pollution Control Act of 1973 and the Title 15A Chapter 4: Sediment Control of the North Carolina Administrative Code.The Town works with Mr. Kenny Llewellyn, Regional Engineer, NCDEQ Mooresville Office to accomplish this minimum measure. The Town receives a portion of its potable water supply from the City of Concord, which as part of its settlement of an Inter-basin Transfer (IBT) Agreement in 2010 instituted some additional regulatory and procedural requirements on riparian buffers and vegetated setbacks. The Town amended its riparian buffers and vegetative setback rules at the time to be consistent with the terms of the IBT agreement and continues to enforce those rules. In addition,the Town is part of the Regional Stormwater Partnership of the Carolinas(RSPC) administered by the Infrastructure, Design, Environment and Sustainability (IDEAS) Center at UNC Charlotte. The Partnership is underwritten with dues from over 20 communities in the Metrolina area and serves as a forum for providing public education and outreach opportunities for its membership. The Town relies on the RSPC to primarily conduct the public education and outreach minimum measure. The Town observes the agreement with the RSPC via a foundation document that outlines contractual obligations, defines goals and establishes memberships.
