PART 1: INTRODUCTION
The purpose of this Stormwater Management Plan (SWMP) is to establish and define the means by which
the Town of Garner 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 Garner 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 NCS000420, 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 Garner and located
within the corporate limits of the Town of Garner.
In preparing this SWMP, the Town of Garner 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.

PART 3: MS4 INFORMATION
3.1 Permitted MS4 Area
This SWMP applies throughout the corporate limits of the Town of Garner, including all regulated
activities associated with the discharge of stormwater from the MS4. The map below shows the corporate
limits of Town of Garner as of the date of this document.
3.2 Existing MS4 Mapping
The current MS4 mapping system consists primarily of reinforced concrete pipe with some corrugated
metal pipe used in mainly residential and commercial areas. Most of the storm water enters the system
through catch basins and some yard inlets. All SCMs that are owned by private developments or HOAs
as well as publicly by the Town of Garner are also mapped within the Town of Garner GIS system, but
not represented on the above map. Maps of the stormwater collection system are updated on a routine
basis as the Town receives as-builts of completed development projects.

Table 1: Summary of Current MS4 Mapping
Percent of MS4 Area Mapped 95 %
No. of Major Outfalls* Mapped ~165 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.
The storm sewer system map was developed with initial criteria and every year starting in 2003,
approximately 95% of the system has been mapped with additional information. The map is in digital
form and paper maps can be created upon request. Discrepancies that were found by field verification
were noted and changed accordingly. The storm sewer system is updated as the town receives as-built
drawings, and any field discrepancies are changed accordingly as they are noted. The maps can be
accessed through the Engineering Department of the Town. The number of major outfalls maps changes
each year as we update our mapping to include new infrastructure. The number of major outfalls mapped
above represents the current number of outfalls that are checked through high priority dry weather
screenings. These numbers are updated within high priority areas when screened as new infrastructure has
been added.

3.7 Industrial Facility Discharges
The Town of Garner MS4 jurisdictional area includes the following industrial facilities which hold
NPDES Industrial Stormwater Permits, as determined from the NCDEQ Maps & Permit Data web page.
Currently there is only one municipal facility owned by the Town of Garner that holds an additional MS4
NPDES Industrial Permit to release stormwater, the Wade H Vester Public Works Center. Municipal
employees are trained annually on pollution prevention and good housekeeping, general stormwater
information, stormwater control measure maintenance and illicit discharges. The municipal facility has an
annual inspection for the vehicle maintenance shop, fueling station and grounds and the outfall on site
that drains the fueling area is inspected twice a year for any stormwater pollution discharges.

3.8 Non-Stormwater Discharges
The water quality impacts of non-stormwater discharges have been evaluated by the Town of Garner as
summarized in Table 6 below. The unpermitted non-stormwater flows listed as incidental do not
significantly impact water quality. The Town of Garner 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 Garner.
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
DRAFT NCS000420 SWMP

PART 8: CONSTRUCTION SITE RUNOFF CONTROL PROGRAM
In accordance with 15A NCAC 02H .0153, the Town of Garner 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 state SPCA
Program is either delegated to a city/town, delegated to a county, or implemented by NCDEQ in non-
delegated areas.

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 Garner 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 Garner 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.
