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 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, 6 and 7.)

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 program(s)that address each. In addition,the Town of Knightdale has evaluated schools, homeowners and businesses as target audiences that are likely to have significant stormwater impacts.

In fiscal year 2024,the Town collected $1,261,369 in user fee revenue with total funding from all sources being$1,662,819. Total expenditures for the same time period were $1,247,337. Reserves for this fund at yearend were $3,099,070. The Town is working on a sustainability project whereby stormwater needs are addressed in both the short and long terms. This includes a 10-year capital improvement plan. 4.3 Shared Responsibility The Town of Knightdale will share the responsibility of implementing the following minimum control measures,which are at least as stringent as the corresponding NPDES MS4 Permit requirement. The Town of Knightdale remains responsible for compliance if the other entity fails to fulfil the permit obligation, and may be subject to enforcement action if neither the Town of Knightdale 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.

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.

These elements are designed to minimize water quality impacts utilizing a combination of structural Stormwater Control Measures (SCMs)and/or non-structural BMPs appropriate for the community, and ensure adequate long- term operation and maintenance of SCMs. In accordance with 15A NCAC 02H.0153 and .1017,the Town of Knightdale implements the following State post-construction program requirements,which satisfy the NPDES Phase II MS4 post-construction site runoff control requirements as Qualifying Alternative Programs(QAPs)in the MS4 area(s)where they are implemented.

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.
