PART 1: INTRODUCTION
The purpose of this Stormwater Management Plan(SWMP)is to establish and define how the Town of
Nashville 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 Nashville will
develop, implement, enforce, evaluate,and report to the North Carolina.Department of Environmental
Quality(NCDEQ)Division of Energy,Minerals and Land Resources(DEMLR)to comply with the MS4
Permit number NCS000485,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 Nashville and located
within the corporate limits of the Town of Nashville.
In preparing this SWMP,the Town of Nashville 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.

3.8 Non-Stormwater Discharges
The water quality impacts of non-stormwater discharges have been evaluated by the Town of Nashville as
summarized in Table 6 below. The unpermitted non-stormwater flows listed as incidental do not
significantly impact water quality.The Town of Nashville 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. Street cleaning is performed with a vacuum street sweeping process that removes excess
debris/sediment/solids and reduces pollutants associated with street washing.The Division has not
required that other non-stormwater flows be specifically controlled by the Town of Nashville.
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 Nashville to determine whether they may
significantly impact water quality.
Dechlorinated swimming pool discharges are considered possible non-stormwater discharges.Therefore,
the Town utilizes Public Education and Outreach BMPs 6-10 to educate businesses and residents about
these potential water quality impacts.
Debris collected in the Town's street sweeper are disposed of as municipal solid waste at the City of
Rocky Mount transfer station. Street washing discharges are addressed under BMP 39 as part of the
Pavement Management Program in Part 10 of this SWMP.

3.9 Target Pollutants and Sources
In addition to those target pollutants identified above,the Town of Nashville is aware of other significant
water quality issues within the permitted MS4 area. These are included in Table 7 below.
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 Nashville has evaluated schools,
homeowners and businesses as target audiences that are likely to have significant stormwater impacts.
Target pollutants include excess nutrients and fecal coliform from pet waste,lawn and garden fertilizers,
and septic system leakage.

In accordance with 15A NCAC 0211.0153,the Town of Nashville relies upon the North Carolina
Sedimentation Pollution Control Act(SPCA)of 1973 and the NCGO10000 permit for construction
activities as qualifying alternative programs to meet the NPDES MS4 Permit requirements for all
construction site runoff control measures to reduce pollutants in stormwater runoff from construction
activities that result in land disturbance of greater than or equal to one acre and any construction activity
that is part of a larger common plan of development that would disturb one acre or more.

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 Nashville 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 Nashville 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
Town of Nashville municipal facilities and operations. Pollution prevention and good housekeeping is
accomplished through the implementation of seven required programs,which collectively address the
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 Town of Nashville will manage, implement,and report the pollution prevention and good
housekeeping BMPs as specified in Table 21 below for each required program.
Table 21: Pollution Prevention and Good Housekeeping BMPs
Permit 3.7.1: Municipal Facilities Operation and Maintenance Program
