PART 1: INTRODUCTION
The purpose of this Stormwater Management Plan (SWMP) is to establish and define the means by which
the City of Newton 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 Newton 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 NCS000397, 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 Newton and located
within the corporate limits of the City of Newton.
In preparing this SWMP, the City of Newton 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.

3.2 Existing MS4 Mapping
The current MS4 mapping includes stormwater inflows, stormwater manholes, stormwater junction
boxes, culvert drain pipes, stormwater discharges, and settling basins. The MS4 area has been mapped.
However, previously unmapped stormwater infrastructure is still occasionally discovered. Stormwater
inflows include information on material, diameter/box size, depth, and ground cover. Culvert drain pipes
include information on diameter, box size, material, ground cover, and length. Stormwater discharges
include information on material, diameter/box size, ground cover, and receiving stream. The stormwater
discharges include outfalls, but a layer identifying only the major outfalls does not exist. Settling basins
includes stormwater control measures and reports information including material, bank material, baffles,
and weir information.
Table 1: Summary of MS4 Mapping
Percent of MS4 Area Mapped 95 %
No. of Major Outfalls* Mapped 0 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.

3.8 Non-Stormwater Discharges
The water quality impacts of non-stormwater discharges have been evaluated by the City of Newton as
summarized in Table 6 below. The unpermitted non-stormwater flows listed as incidental do not
significantly impact water quality. The City of Newton has evaluated residential and charity car washing
for possible significant water quality impacts. Street cleaning is performed with a dry street sweeping
process so street washing discharges are not relevant to the MS4.
The Division has not required that other non-stormwater flows be specifically controlled by the City of
Newton.
DRAFT NCS000397 SWMP
City of Newton
August 19, 2019
Page 8
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 Newton to determine whether they may
significantly impact water quality. They were determined to be a possible cause of water quality impacts
and will be addressed through public education efforts (See BMP No. 5).

3.9 Target Pollutants and Sources
In addition to those target pollutants identified above, the City of Newton is not aware of other significant
water quality issues within the permitted 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. In addition, the City of Newton has evaluated schools, homeowners and
businesses as target audiences that are likely to have significant stormwater impacts. The schools were
selected as a target audience due to the opportunity to affect positive change through education and
involvement opportunities. Homeowners and businesses were identified as target audiences because they
are likely sources of non-point pollution through poor management practices.

4.2 Program Funding and Budget
In accordance with the issued permit, the City of Newton shall maintain adequate funding and staffing to
implement and manage the provisions of the SWMP and comply with the requirements of the NPDES
MS4 Permit. The budget includes the permit administering and compliance fee, which is billed by the
Division annually.
The stormwater program currently receives funding of approximately $750,000 per year; this is funded
primarily through general funds. However, the Assistant Public Works Director and Utilities Director
positions are funded through the Public Works Enterprise fund. In total the program receives 2 full-time
equivalent staff for pavement management (1 full time street sweeper position and a leaf collection crew
seasonally (13 weeks)) and less than 0.5 dedicated full-time equivalent staff for other program
components.
The program is currently under-funded to conduct all the proactive elements of the permit. Further fiscal
analysis and investigation of funding options (such as additional general fund allocation or a stormwater
fee) will be conducted as indicated in BMP No. 3 in order to fully fund the program by permit year three.
4.3 Shared Responsibility
The City of Newton will share the responsibility to implement the following minimum control measures,
which are at least as stringent as the corresponding NPDES MS4 Permit requirement. The City of
Newton remains responsible for compliance if the other entity fails to perform the permit obligation and
may be subject to enforcement action if neither the City of Newton nor the other entity fully performs the
permit obligation. Table 9 below summarizes who will be implementing the component, what the
component program is called, the specific SWMP BMP or permit requirement that is being met by the
shared responsibility and whether or not a legal agreement to share responsibility is in place.

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 Newton 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 Newton 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

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