This SWMP identifies the specific elements and minimum measures that the City of Mount Holly 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 NCS000407, 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 Mount Holly and located within the corporate limits of the City of Mount Holly. In preparing this SWMP, the City of Mount Holly 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.

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 City of Mount Holly MS4 is located within the Catawba 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 Dutchman's Creek 11-119- 0.5 Turbidity Catawba River 11- 117 PCB Fish Tissue Advisory Fites Creek 11-121- 1 None Known Taylors Creek 11-119-5 None Known Stanley Creek 11-119-3- 2 None Known South Stanley Creek 11-119-4 None Known 3.4 MS4 Interconnection The City of Mount Holly 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.

This plan points to collaborative efforts to deal with nonpoint sources of pollution into the Catawba River. General non -point source pollution such as fertilizer runoff is targeted as part of Public Education and Outreach efforts. 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, 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, the species listed in table 4 have the potential to occur within the regulated MS4 urbanized area. Of those species listed, Table 4 summarizes the species that may be significantly impacted by the quality of surface waters within their habitat.

City -owned facilities are also inspected as part of the Pollution Prevention and Good Housekeeping program BMP No. 33. DRAFT NCS000407 SWMP City of Mount Holly 10/5/2021 Page 6 3.8 Non-Stormwater Discharges The water quality impacts of non-stormwater discharges have been evaluated by the City of Mount Holly as summarized in Table 6 below. The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality. The City of Mount Holly has evaluated residential and charity car washing and street washing for possible significant water quality impacts. 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 Mount Holly to determine whether they may significantly impact water quality. The City of Mount Holly has evaluated the locations where public works vehicles are cleaned and have determined that the locations are sufficient for protecting water quality. The City utilizes Public Education and Outreach and Pollution Prevention and Good Housekeeping BMPs to educate residents and municipal staff on the possible effects of detergents entering the surface waters. 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 City of Trinity.

The state SPCA Program is either delegated to a city/town, delegated to a county, or implemented by NCDEQ in non -delegated areas.
