PART 1: INTRODUCTION

The purpose of this Stormwater Management Plan (SWMP) is to establish and define the means by which
the Town of Dallas 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 Dallas 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 NCS000393, 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 Dallas and located
within the corporate limits of the Town of Dallas.

In preparing this SWMP, the Town of Dallas 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.

PART 3: MS4 INFORMATION

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

3.2 Existing MS4 Mapping
The current MS4 mapping includes the major outfalls and receiving streams. At this time, the map only
includes references to stormwater structures, pipes, and drainage patterns through topographic
information. During the period covered by this permit, the MS4 map will be enhanced to specifically
locate all stormwater control infrastructure such as catch basins, ditches, storm drainage pipes, etc.

[insert link to public MS4 GIS map, if available]

*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 Dallas MS4 is located within the Catawba 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:

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 Dallas 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 Dallas has adopted the following
Gaston County post-construction program requirements, as contained in the Gaston County Stormwater
Ordinance , 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. The Town of
Dallas authorized enforcement of this ordinance by the Gaston County Department of Natural Resources
through adoption of an Interlocal Agreement dated June 13, 2007.

PART 10: POLLUTION PREVENTION AND GOOD HOUSEKEEPING PROGRAMS
This SWMP provides a comprehensive pollution prevention and good housekeeping strategy for the
Town of Dallas 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
Currently, spill response procedures are handled by the Fire Department, while all other components of
the Pollution Prevention and Good Housekeeping Program are implemented by the Public Works
Department. Initially, an inventory of municipal facilities will be completed to serve as a basis for
developing the program and creating documentation for inspections. The Town already provides leaf
collection services to residents but will begin to quantify and monitor for assessment.
The Town of Dallas will manage, implement and report the pollution prevention and good housekeeping
BMPs as specified in Table 21 below for each required program.
