This SWMP identifies the specific elements and minimum measures that the City of Greenville 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 NCS000437, 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 Greenville and located within the corporate limits of the City of Greenville. In preparing this SWMP, the City of Greenville 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.

The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality. The City of Greenville 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 City of Greenville. 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 Greenville to determine whether they may significantly impact water quality. They were determined to be a possible cause of water quality impacts and will be addressed through public education efforts (See BMP No. 5.1).

The budget includes the permit administering and compliance fee, which is billed by the Division annually. The stormwater program currently receives budgeted funding of approximately $6,059,820 per year; this is funded entirely through the Stormwater Utility Fund. In total the program receives 41.10 full-time equivalent staff for program administration, capital engineering, inspections and enforcement, plan reviews, and drainage maintenance. The Stormwater Utility Fund is an enterprise fund established to implement the City's Stormwater Management Program. Revenues are generated through a Stormwater fee to support the program efforts. FY 2021 will see the continued implementation of increased preventative maintenance of stormwater infrastructure, and further planning for increased capital project and infrastructure spending. A fund balance appropriation will be made in the amount of $1.5 million for new staffing and equipment, with rate increases planned for recurring capital and infrastructure spending. The preventive maintenance program represents the first step in the City's implementation of the Watershed Master Plan recommendations as formulated by the Stormwater Advisory Committee. The service levels will create a system of policies and procedures intended to create a higher level of oversight related to the maintenance and development of the City's stormwater infrastructure. The level of preventive maintenance included in the approved stormwater plan will require the addition of approximately 16 staff positions and investment in various pieces of capital equipment. The City began increasing staff during FY 2020 with the hiring of administrative support staff and an asset manager. The remaining positions will continued to be recruited with the plan to have the preventive maintenance program being fully operational for FY 2021. Annual funding for preventive maintenance is projected to total approximately $1.5 million, which will be funded through increases in stormwater fees that are scheduled to begin in FY 2022. The approved plan includes a $1.00 increase in the monthly stormwater rate each year for four years. For FY 2021, the monthly stormwater rate remains constant at $5.35/ERU. DRAFT NCS000437 SWMP City of Greenville February 15, 2021 Page 14 4.3 Shared Responsibility The City of Greenville will share the responsibility to implement the following minimum control measures, which are at least as stringent as the corresponding NPDES MS4 Permit requirement. The City of Greenville remains responsible for compliance if the other entity fails to perform the permit obligation, and may be subject to enforcement action if neither the City of Greenville 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.

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 List of Municipal Industrial Facilities Requiring Individual NPDES Permits: • City of Greenville Public Works Complex — NCG080686 Industrial Permit. The City maintains operation and maintenance procedures for all municipal facilities. Annual inspections are conducted by the Fire/Rescue Department and Engineering Department and monthly by Public Works Staff to identify unsafe conditions, including the potential for discharging of hazardous materials. The City routinely conducts self -inspections to insure OSHA compliance. The Public Works facility is covered by a NCG08 industrial stormwater permit. Inspection, sampling, and maintenance procedures are detailed in the facility's Stormwater Pollution Prevention Plan. A SWPPP for the Public Works Complex has been developed and is updated annually. The municipal operations that will be impacted by this operation and maintenance program would be the following: the Street Maintenance Division, Buildings and Grounds Division, Sanitation Division, Fleet Maintenance Division, Transit Division, and Recreation and Parks Department Operation and Maintenance, which would include Bradford Creek Municipal Golf Course. The City of Greenville will manage, implement and report the pollution prevention and good housekeeping BMPs as specified in Table 21 below for each required program.
