PART 1: INTRODUCTION
The purpose of this Stormwater Management Plan (SWMP) is to establish and define the means by which
the City of Greenville will comply with its National Pollutant Discharge Elimination System (NPDES)
Municipal Separate Storm Sewer System (MS4) Permit and the applicable provisions of the Clean Water
Act to meet the federal standard of reducing pollutants in stormwater runoff to the maximum extent
practicable.
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.

3.2 Existing MS4 Mapping
The current MS4 GIS mapping includes stormwater inflows, stormwater manholes, stormwater junction
boxes, culvert drain pipes, ditches, and stormwater discharges (pipe ends). The entire MS4 area has been
mapped and is regularly updated as infrastructure is repaired/replaced/added/removed or as errors or
missing information is discovered. Stormwater inflows include information on material, diameter/ box
size, depth, inverts, and ground cover. Culvert drain pipes include information on diameter, box size,
material, inverts, ground cover, and length. Stormwater discharges include information on material,
diameter/box size, inverts, ground cover, and receiving stream.
Table 1: Summary of MS4 Mapping
Percent of MS4 Area Mapped 99 %
No. of Major Outfalls* Mapped 287 total
*A Major 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.

3.8 Non-Stormwater Discharges
The water quality impacts of non-stormwater discharges have been evaluated by the City of Greenville as
summarized in Table 6 below. 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).

4.2 Program Funding and Budget
In accordance with the issued permit, the City of Greenville shall maintain adequate funding and staffing
to implement and manage the provisions of the SWMP and comply with the requirements of the NPDES
MS4 Permit. 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.

PART 10: POLLUTION PREVENTION AND GOOD HOUSEKEEPING PROGRAMS
This SWMP provides a comprehensive pollution prevention and good housekeeping strategy for the City
of Greenville municipal facilities and operations. 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.
