PART 1: INTRODUCTION

The purpose of this Stormwater Management Plan (SWMP) is to establish and define the means by which
the Town of Ayden 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 Town of Ayden 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 NCS000500, 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 Ayden and located within
the corporate limits of the Town of Ayden.

In preparing this SWMP, the Town of Ayden 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.

3.1 Permitted MS4 Area
This SWMP applies throughout the corporate limits of the Town of Ayden, including all regulated
activities associated with the discharge of stormwater from the MS4. The map below shows the corporate
limits of Town of Ayden as of the date of this document.

3.2 Existing MS4 Mapping

NCS000500 SWMP
Town of Ayden
October 25, 2020
Page 4

The Town of Ayden maintains a Geographic Information System (GIS) database that includes detailed
geospatial information related to the Town’s storm sewer conveyance system. The database also includes
geospatial information related to drainage areas, receiving streams, land use, zoning, floodplain data, and
other pertinent data. This information is updated periodically.

Pursuant to the Town of Ayden’s current permit, components of their MS4 were mapped using Global
Positioning System (GPS) technology and are included in the GIS. The Town will update the GIS
Stormwater Layer to reflect changes to the MS4 as necessary. This may include updating stormwater system
components for new development, repairs, and maintenance, in addition to updating stream data based on
surface water identification requests. Mapping updates of the MS4 is solely the Town’s responsibility.

Table 1: Summary of MS4 Mapping
Percent of MS4 Area Mapped 60 %
No. of Major Outfalls* Mapped 1 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.

3.3 Receiving Waters
The Town of Ayden 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:

3.8 Non-Stormwater Discharges
The water quality impacts of non-stormwater discharges have been evaluated by the Town of Ayden as
summarized in Table 6 below. Non-stormwater discharges were identified based on guidance from the
Department of Environmental Quality. Town staff reviewed the potential sources for a description of
potential impact to water quality (results summarized in Table 6). The unpermitted non-stormwater flows
listed as incidental do not significantly impact water quality. The Town of Ayden has evaluated residential
and charity car washing and street washing for possible significant water quality impacts.

NCS000500 SWMP
Town of Ayden
October 25, 2020
Page 8

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 Ayden.

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 Ayden to determine whether they may significantly impact
water quality.
