PART 1: INTRODUCTION
The purpose of this Stormwater Management Plan(SWMP)is to establish and define the means by which the
Town of Benson 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 Benson 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
NCS000558, 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 Benson and located within the corporate limits of the Town
of Benson.
In preparing this SWMP,the Town of Benson 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.

3.8 Non-Stormwater Discharges
The water quality impacts of non-stormwater discharges have been evaluated by the Town of Benson as
summarized in Table 6 below. The unpermitted non-stormwater flows listed as incidental do not significantly
impact water quality. The Town of Benson 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 Benson.
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 Benson to determine whether they may significantly impact water quality.

3.9 Target Pollutants and Sources
Based upon observations by Town staff and complaints from citizens,litter and yard waste has been identified as
a stormwater pollutant.
NCS000558 SWMP
April 19, 2023
Page 6
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 Benson has evaluated schools,homeowners and businesses as target
audiences that are likely to have significant stormwater impacts.
The Town of Benson addresses litter and yard waste pollutants by reaching out to individual property owners that
are not in compliance with Town Ordinances. The Town conducts a community litter sweep in April each year.
Also,the Public Works Department operates a street sweeper and collects yard waste weekly.
The MOU with Johnston County targets sediment and nitrogen management through the new development
requirements, with contractors, developers and engineers as targeted audiences. Homeowners are also a targeted
audience for nutrients and general water quality through tracking built upon area during the building permit
process. This education occurs by both the County and the Town.

PART 9: POST-CONSTRUCTION SITE RUNOFF CONTROL PROGRAM
This SWMP identifies the minimum elements to develop, implement and enforce a program to address
stormwater runoff from new development and redevelopment projects that disturb greater than or equal to one
acre,including projects less than one acre that are part of a larger common plan of development or sale, that are
located within the Town of Benson and discharge into the MS4. 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 Benson 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.
