This SWMP identifies the specific elements and minimum measures that the Town of Knightdale 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 NCS000460, 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 Knightdale and located within the corporate limits of the Town of Knightdale. In preparing this SWMP, the Town of Knightdale 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.

The map below shows the corporate limits of the Town of Knightdale as of the date of this document. DRAFT NCS000460 SWMP Town of Knightdale 08/19/2021 Page 4 3.2 Existing MS4 Mapping The current MS4 mapping includes stormwater inflows, culvert drain pipes, channels, stormwater discharges, and SCM devices. Roughly 85% of the towns MS4 system has been mapped to date. However, previously unmapped stormwater infrastructure is still occasionally discovered and included. Stormwater inflows include information on material, diameter/box size, and length. Culvert drain pipes include information on diameter, box size, material, and length. Stormwater discharges include information on material, diameter/box size, and ownership. The stormwater discharges mapped include all outfalls, including 79 major outfalls meeting the designated criteria listed below. SCM devices mapped include information on facility type and ownership values. Table 1: Summary of Current MS4 Mapping Percent of MS4 Area Mapped 95 % No. of Major Outfalls* Mapped 79 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. DRAFT NCS000460 SWMP Town of Knightdale 08/19/2021 Page 5 3.3 Receiving Waters The Town of Knightdale MS4 is located within the Neuse 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 Beaver Dam Creek 27-29 C;NSW Not Listed Milburnie Creek 27-31 C;NSW Not Listed Mingo Creek 27-32 C;NSW Not Listed Poplar Creek 27-35 C;NSW Not Listed Marks Creek (Lake Myra) 27-38 C;NSW Not Listed 3.4 MS4 Interconnection The Town of Knightdale MS4 is interconnected with another regulated MS4 and directly discharges to the receiving waters as listed in Table 2 above. The MS4 does interconnect with the statewide NCDOT MS4 and includes: a. The interconnection is receiving stormwater from the NCDOT MS4. The number of interconnections is unknown. Quantity: N/A b.

The Town of Knightdale MS4 mapping does not identify interconnections with the NCDOT MS4. d. The Town of Knightdale MS4 mapping does include NCDOT MS4 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 DRAFT NCS000460 SWMP Town of Knightdale 08/19/2021 Page 6 directly receiving discharges from the permitted MS4, and whether a Water Quality Recovery Program has been implemented to address the WLA.

The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality. The Town of Knightdale 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 Knightdale. 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 Knightdale to determine whether they may significantly impact water quality. They were determined to be a possible source of water quality impacts and will be addressed through public education and outreach efforts. (See BMPs No. 3 and 6.)

The SPCA requirements include reducing pollutants in stormwater runoff from construction activities that result in land disturbance of greater than or equal to one acre, and includes any construction activity that is part of a larger common plan of development that would disturb one acre or more. The state SPCA Program is either delegated to a city/town, delegated to a county, or implemented by NCDEQ in non- delegated areas.

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 Currently, large scale spill response procedures are handled by the Knightdale Fire Department while all other components of the pollution prevention and good housekeeping measures are implemented by the Public Works Department. The Town already provides street sweeping and yard waste collection services to residents but will begin to quantify and monitor for assessment. A facility inventory was completed in 2019 and will serve as the basis for developing the program and creating documentation for inspection requirements. The Town of Knightdale will manage, implement and report the pollution prevention and good housekeeping BMPs as specified in Table 21 below for each required program.
