PART 1: INTRODUCTION
The purpose of this Stormwater Management Plan (SWMP) is to establish and define the means by which
The City of Gastonia 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 Gastonia 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 NCS000429, 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 Gastonia and located
within the corporate limits of The City of Gastonia.
In preparing this SWMP, The City of Gastonia 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.

While no WLA exists for the City of Gastonia, TMDL pollutants are the subject of education and
outreach to the public as a means of highlighting the deleterious impacts that they have on water quality.
In addition, the City of Gastonia participates in an off right-of-way program that financially assists
citizens who are contributing to sedimentation in waterways which is the primary transport method of the
TMDLs identified in Table 3. This helps enhance not only education, but also provides a practical
solution for mitigating TMDLs in our community.

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

3.9 Target Pollutants and Sources
In addition to those target pollutants identified above, The City of Gastonia is aware of other significant
water quality issues within the permitted MS4 area. These include sediment, illicit discharges
(eg..sanitary overflows), litter, and yard waste.
Littering is not isolated to one area or neighborhood, The City of Gastonia has become aware of the fact
that it is often more prevalent in locations where there is heavy foot traffic and public gathering spaces.
Areas such as municipal greenways and parks are particularly susceptible to this form of pollution.
Another, more deleterious form of pollution is sedimentation. The lion share of this method of pollution is
from rapid development of the land. The City of Gastonia's primary soil type is a Cecil Urban Complex
and Helena Urban Complex. Both soil types have been classified as Highly Erodible Land (HEL) as
determined by the USDA-NRCS. Consequently, the land is prone to contribute to sedimentation and is a
target pollution that has gained great attention in this area.
DRAFT NCS000429 SWMP
City of Gastonia
06/02/2020
Page 8

Yard Waste is also a pollution source which is heightened during both spring and fall as the change of
season brings yard debris/waste to street inlets. As a result, higher concentrations of ambient elements,
such as Nitrogen and Phosphorous can discharge into the MS4.
Sanitary sewer overflows can also be problematic during heavy rain events and improper disposal of
chemicals from citizens can occur on occasion.
Incidents of both pollution and sedimentation have been reported by the public and overtime The City of
Gastonia has taken several steps toward reducing the number of incidents within the MS4 area.
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 Gastonia 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 Gastonia 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 City of Gastonia 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 City of Gastonia 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.

PART 10: POLLUTION PREVENTION AND GOOD HOUSEKEEPING PROGRAMS
This SWMP provides a comprehensive pollution prevention and good housekeeping strategy for The City
of Gastonia 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
7. Pavement Management Program
The City of Gastonia will manage, implement and report the pollution prevention and good housekeeping
BMPs as specified in Table 21 below for each required program.
