This SWMP identifies the specific elements and minimum measures that the Town of Apex 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 NCS000446, 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 Apex and located within the corporate limits of the Town of Apex. In preparing this SWMP,the Town of Apex 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.

Stormwater from streets, rooftops, parking lots, and other impervious surfaces is generally collected in curb inlets and conveyed by underground pipe systems. In some cases,stormwater runoff flows either by grass-lined swale,ditch or sheet flows to the nearest receiving stream. In accordance with riparian buffer regulations, stormwater discharges must attain diffuse flow prior to entry into the buffer. MS4 Map: https://gisdata-apexnc.opendata.arcgis.com/apps/apex-utility-distribution/explore Table 1: Summary of Current MS4 Mapping Percent of MS4 Area Mapped 99.9 % No. of Major Outfalls* Mapped 138 total *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.

The MS4 does interconnect with the statewide NCDOT TS4 and includes: a. The interconnection is receiving stormwater from the NCDOT TS4. b. The interconnection is discharging stormwater into the NCDOT TS4. The number of interconnections is unknown. Quantity:N/A. NCS000446 SWMP Town of Apex July 2024 Page 5 c. Where possible,the Town of Apex TS4 mapping does identify interconnections with the NCDOT MS4. d. Where possible,the Town of Apex MS4 mapping does include NCDOT TS4 outfalls. 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) Neuse River Estuary Total Nitrogen N N Swift/Williams Creek Biological Integrity Y Y Jordan Lake Total Phosphorous,Total N N Nitrogen The Swift Creek watershed in the northeast section of Apex has been identified with a WLA. Focused stormwater pollution prevention efforts have been implemented Town-wide to help address this. The Town of Apex website has a page devoted to homeowner education and specifically how to slow the flow of runoff and promote healthy streambanks. This includes instructions on rain garden installation, reduced fertilizer use, downspout disconnection, and an NC Cooperative Extension publication on Small-Scale Solutions for Repairing Eroded Streambanks. The Town has contracted with a company for street sweeping services. Downtown Apex is swept every two weeks, Town parking lots are swept monthly,main thoroughfares(including NCDOT streets)are also swept monthly, and all residential neighborhoods are swept on a quarterly basis. Any residential areas within the Swift Creek watershed are swept on a monthly basis instead of quarterly as part of the Water Quality Recovery Program. NCS000446 SWMP Town of Apex July 2024 Page 6 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.Based upon 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.

The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality. The Town of Apex 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 Apex. Wash water associated with car washing that does not contain detergents or does not discharge directly into the MS4 is considered incidental. Non-commercial car washing is exempt from the Town's IDDE ordinance and is considered to be any occasional automotive washing performed by individuals or groups without charging any fee or in exchange for a charitable donation. This shall include but is not limited to car washes performed by local church groups, school groups, athletic teams, youth organizations, and individuals at their place of residence. However,these types of non-stormwater discharges that do contain detergents have been evaluated by the Town of Apex to determine whether they may significantly impact water quality.
