PART 1: INTRODUCTION
The purpose of this Stormwater Management Plan (SWMP) is to establish and define the means by which
the Village of Clemmons 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 Village of Clemmons 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 NCS000410, as issued by NCDEQ. This permit covers activities associated with
the discharge of stormwater from the MS4 as owned and operated by the Village of Clemmons and
located within the corporate limits of the Village of Clemmons.
In preparing this SWMP, the Village of Clemmons 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.

No. of Major Outfalls* Mapped 150 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.
**New construction areas, or new areas annexed within the Village of Clemmons will require
new/updated mapping, along with finding current MS4 infrastructure that currently cannot be found, or
additional areas within private property that we cannot access at this time.
3.3 Receiving Waters
The Village of Clemmons is located within the Yadkin Pee-Dee 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:

The Village of Clemmons will continue to partner with the City of Winston-Salem Erosion control
department to help report violations of construction site sediment and erosion control. Along with this, the
Village of Clemmons has implemented a quantity control ordinance that requires all new and
redevelopment to adhere to quantity control devices for any land disturbance of 20,000 square feet or
greater. All impervious additions to the site within that disturbance must be mitigated to the current
Village of Clemmons design storm standards, along with all quality control requirements set forth by the
NCDEQ Minimum Design Criteria (MDC). These ordinances should help reduce the rate of stream bank
erosion downstream of all new construction sites and to allow time for stabilization and ecosystem
restoration to occur.

3.8 Non-Stormwater Discharges
The water quality impacts of non-stormwater discharges have been evaluated by the Village of Clemmons
as summarized in Table 6 below. The unpermitted non-stormwater flows listed as incidental do not
significantly impact water quality. The Village of Clemmons has evaluated residential and charity car
washing and street washing for possible significant water quality impacts. With the majority of
community car washes within Clemmons, some of the discharged soapy water did make its way to a
storm drain, however the majority of the runoff either flowed to a vegetated area or there was some kind
of device around the storm drain blocking the suds from entering the drain, but allowing the water to flow
through. The car washing was determined to be a possible cause of water quality impact and will be
addressed through public education efforts as well as enforcement on reoccurring situations. Street
cleaning is performed with a controlled wet vacuum street sweeping process that removes excess solids
along the curb lines that will significantly reduce any impactful solids discharged with street washing.
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
Village of Clemmons.
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 Village of Clemmons to determine whether they may
significantly impact water quality. They were determined to be a possible cause of water quality impact
and will be addressed through public education efforts as well as enforcement on reoccurring situations.

3.9 Target Pollutants and Sources
In addition to those target pollutants identified above, the Village of Clemmons is aware of other
significant water quality issues within the permitted MS4 area. These include trash (gross solids),
nitrogen, phosphorus and bacteria such as fecal coliform. These acknowledgements come from daily
inspections of the municipality and public participations events such as annual cleanups. Pet waste and
Sanitary Sewer Overflows in the community will always be a contributor of nitrogen, phosphorus, and
bacteria in the Village of Clemmons. The Village of Clemmons has implemented public participation and
education through the scheduled community cleanups throughout the year, and created a pet waste
installation program to install pet waste stations throughout Clemmons and help educate residents the
importance of picking up their pets waste. The Village of Clemmons will continue to educate the public
and enforce, as needed, for these illicit violations.
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 Village of Clemmons has evaluated schools,
homeowners and businesses as target audiences that are likely to have significant stormwater impacts.

4.2 Program Funding and Budget
In accordance with the issued permit, the Village of Clemmons 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.
Funding for the Stormwater Management Program comes primarily from the Stormwater Utility Fee. The
Utility Fee is based on equitable cost-sharing measures which allocate responsibility to users of the
stormwater management system. The property's contribution to runoff is defined by impervious coverage
per developed tract of land. Both commercial and non-commercial developments are charged a fee and
includes for-profit and not-for-profit property owners. Billable Equivalent Residential Unit (ERU) fees
are currently $5 per ERU per month, equating to $60 per ERU annually. Each single-family dwelling unit
is billed one ERU annually. Non-residential development is billed a multiple of ERUs, with
approximately 3,952 square feet of impervious area equaling one ERU. These fees are billed on the
annual County Property Tax Assessment. You can view Frequently Asked Questions for more answers
about the Stormwater Fee FAQ located at
https://www.clemmons.org/DocumentCenter/View/313/Stormwater-Frequently-Asked-Questions-PDF.

4.3 Shared Responsibility
The Village of Clemmons 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
Village of Clemmons remains responsible for compliance if the other entity fails to perform the permit
obligation, and may be subject to enforcement action if neither the Village of Clemmons 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. This agreement renews every year until otherwise specified. See official agreement below dated

PART 10: POLLUTION PREVENTION AND GOOD HOUSEKEEPING PROGRAMS
This SWMP provides a comprehensive pollution prevention and good housekeeping strategy for the
Village of Clemmons 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
