PART 1: INTRODUCTION
The purpose of this Stormwater Management Plan(SWMP) is to establish and define the means by which
the City of Graham 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 Graham 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 NCS000408 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 Graham and located
within the corporate limits of the City of Graham.
In preparing this current SWMP,the City of Graham has evaluated its MS4,the permit requirements of
it's MS4,and previous Comprehensive Stormwater Management Plans 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 City of Graham as
summarized in Table 6 below. The unpermitted non-stormwater flows listed as incidental do not
significantly impact water quality. The City of Graham 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 Graham.
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 Graham to determine whether they may
significantly impact water quality. Currently runoff from car washing in The City of Graham would be
considered incidental.

3.9 Target Pollutants and Sources
In addition to those target pollutants identified below,the City of Graham is not aware of other significant
water quality issues within the permitted MS4 area.
The education program will target total suspended solids and nutrient loading because turbidity,
sedimentation, and nutrients are the pollutants of concern in downstream waters. In addition, floatables,
trash,and debris will also be targeted. The education program will also address the proper use and disposal
of typical household chemicals, garden chemicals, and used motor oil.
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 City of Graham has evaluated schools,
homeowners and businesses as target audiences that are likely to have significant stormwater impacts.

PART 8: CONSTRUCTION SITE RUNOFF CONTROL PROGRAM
In accordance with 15A NCAC 02H .0153,the City of Graham relies upon the North Carolina
Sedimentation Pollution Control Act(SPCA)of 1973 as a qualifying alternative program to meet a
portion of the NPDES MS4 Permit requirements for construction site runoff control measures. The
SPCA requirements include reducing pollutants in stormwater runoff from construction activities that
result in land disturbance of greater than or equal to one acre and includes any construction activity that is
part of a larger common plan of development that would disturb one acre or more.
The contact information for the responsible party for Construction Site Runoff Controls within the
City of Graham is:

PART 9: POST-CONSTRUCTION SITE RUNOFF CONTROL PROGRAM
The City of Graham operates a Post Construction Site Runoff Control Program that regulates 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 City of Graham 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.
The City also operates a high-density water supply watershed program that is handled similarly to it's
Post Construction runoff program but which includes reduced triggers and more stringent regulations.
The City's post construction ordinance is contained in Section 157 of it's Code of Ordinances. The City
maintains a stormwater design manual that is deemed equal or more stringent than the NC DEQ BMP
Manual.
The annual reporting metrics for the post construction program are provided in Table 20: Post
Construction Site Runoff Control BMPs below.
