PART 1: INTRODUCTION
The purpose of this Stormwater Management Plan (SWMP) is to establish and define the means by which
the Town of Carrboro 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 Carrboro 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 NCS000450, 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 Carrboro and located
within the corporate limits of the Town of Carrboro.
In preparing this SWMP, the Town of Carrboro 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.

3.2 Existing MS4 Mapping
The current MS4 mapping includes these layers: inlets, outlets (outfalls), junctions/manholes, clean outs,
pipes, culverts, open channels, and SCMs. Attributes are provided for owner (some non -Town
owned/maintained assets are mapped) sizes, materials, inverts, and more.

lec **v
*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. Carrboro footnote: all drainage features
with drainage areas > 50 acres are regulated streams and not considered to be part of the MS4 in
Carrboro. (Carrboro regulates ephemeral streams with > 5 acres of drainage areas in addition to
intermittent and perennial streams.) Major outfalls are therefore defined in the above table based on pipe
size alone. Note that for illicit discharge purposes, Carrboro has also included smaller pipe sizes as
priority outfalls for illicit discharge purpose. With the exception of the Town's Public Works (with a
Vehicle Maintenance Area general permit), the one industrial site in Carrboro's municipal limits that
meets the definition provided above is a cement plant on State (UNC) property that is regulated through
UNC's MS4 and a State industrial permit.
3.3 Receiving Waters
The Town of Carrboro MS4 is located within the Cape Fear 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:

benthos/aquatic life.
3.4 MS4 Interconnection
The Town of Carrboro MS4 is interconnected with another regulated MS4 and directly receives
stormwater from the Town of Chapel Hill MS4. The number of interconnections entering the Town of
Carrboro MS4 from the Town of Chapel Hill is 5, as determined by GIS analysis of MS4 data
The Town of Carrboro MS4 is interconnected with another regulated MS4 and directly discharges
stormwater into the Town of Chapel Hill MS4. The number of interconnections leaving the Town of
Carrboro MS4 to the Town of Chapel Hill is 6, as determined by GIS analysis of MS4 data.
The MS4 does interconnect with the statewide NCDOT MS4 and includes:
a. The interconnection is receiving stormwater from the NCDOT TS4. The number of
interconnections is unknown.

b. The interconnection is discharging stormwater into the NCDOT TS4. The number of
interconnections is unknown.
c. The Carrboro MS4 mapping does not identify interconnections with the NCDOT TS4.
d. The Carrboro MS4 mapping does not include NCDOT TS4 outfalls.
3.5 Total Maximum Daily Loads (TMDLs)
The TMDL(s) listed in Table 3 below have been approved within the MS4 area, as determined by the map
and list provided on the NCDEQ Modeling & Assessment Unit web page. The table also indicates
whether the approved TMDL has a specific stormwater Waste Load Allocation (WLA) for any watershed
directly receiving discharges from the permitted MS4, and whether a Water Quality Recovery Program
has been implemented to address the WLA.

While the TMDL for chlorophyll a in Jordan Lake has not yet resulted in load allocations, a nitrogen load
reduction goal of 35% and phosphorus load reduction goal of 5% for the Upper New Hope Arm has been
identified. The Town has included post construction requirements for nitrogen and phosphorus to prevent
increases since 2007 under a state Nutrient Sensitive Waters Strategy. The Jordan Lake TMDL was
amended in 2014, and includes a TMDL for turbidity in the Upper New Hope arm, but, associated load
reductions have not been assigned.
Carrboro has developed regulations and completed annual reporting to comply with the Jordan Lake
Rules and will continue to track ongoing implementation of the Jordan Lake Rules during this permit
cycle. Carrboro also is a participant in the Bolin Creek Watershed Restoration Team, supported the
development of a 9-step watershed restoration plan for Bolin Creek under the Use Restoration Waters
program, and will continue to pursue watershed restoration activities as presented in the plan.
3.6 Endangered and Threatened Species and Critical Habitat
Significant populations of threatened or endangered species and/or critical habitat are identified within the
regulated MS4 urbanized area. Based upon a review of the Endangered and Threatened Species and
Species of Concern by County for North Carolina Map and Listed species believe to or known to occur in
North Carolina map as provided by the U.S. Fish and Wildlife Service, the species listed in Table 4 have
the potential to occur within the regulated MS4 urbanized area. Of those species listed, Table 4

Note that NCG210452 (JV Brockwell Trucking) is in Carrboro's Planning Jurisdiction (Transition Area)
and NCG020749 (Tony Merritt Gravel Pit) is in the ETJ, but neither is in the municipal limits.
3.8 Non-Stormwater Discharges
The water quality impacts of non-stormwater discharges have been evaluated by the Town of Carrboro as
summarized in Table 6 below. The unpermitted non-stormwater flows listed as incidental do not
significantly impact water quality.
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 not
required that other non-stormwater flows be specifically controlled by the Town of Carrboro.
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 or do discharge to the MS4 have been evaluated by the Town of Carrboro to determine
whether they may significantly impact water quality. With some residential/charity/community car
washes in Carrboro, some of the discharged soapy water may make its way to a storm drain, however in
many cases of the runoff either flows to a vegetated area or there is some kind of containment or at least a
means of blocking the suds from entering the drain, but allowing the water to flow through. Also, the
Town of Carrboro is aware that mobile car washing is a significant source of metals. Car washing has
therefore been determined to be a possible cause of water quality impact and will be addressed through
public education efforts as well as enforcement on reoccurring situations. Water from water lines and fire
hydrants is also a possible source if not dechlorinated. HVAC cleaning operations, and particularly

commercial and higher density sites with directly connected drains, are typically performed with caustic
chemicals and pose a pollution risk.

3.9 Target Pollutants and Sources
In addition to those target discharges identified above, the Town of Carrboro is aware of other significant
water quality issues and pollutants within the permitted MS4 area. These include sediment, nitrogen,
phosphorus, bacteria such as fecal coliform and trash/litter. These acknowledgements come from daily
inspections of the municipality and public participation events such as annual cleanups. Sediment is
attributed to development and construction as well as landscaping practices and gullying and stream bank
erosion. Carrboro's soils are inherently subject to erosion.
While litter is a general issue, there are "hot spots" near a relatively small subset of neighborhoods and
commercial developments. Pet wastes, leaking sewers, sanitary sewer overflows, and improper leaf
collection practices by residents have been a contributor of nitrogen, phosphorus, and bacteria in the
Town of Carrboro. The Town of Carrboro has implemented public participation and education as
discussed in the following sections of this plan, and installed pet waste stations throughout Carrboro to
educate residents about the importance of picking up their pet's waste. The Town of Carrboro will
continue to educate the public and enforce, as needed, for these target pollutants and sources.
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 Carrboro has evaluated schools,
homeowners and businesses as target audiences that are likely to have significant stormwater impacts.
DRAFT NCS000450 SWMP
Town of Carrboro
3/10/2021
Page 9

There are three elementary schools, a middle school, and a high school in Carrboro. These schools are a
priority audience because of the degree of development with these large sites, the ability to reach a large
portion of the population through the schools, and the shared public purpose. One (Carrboro Elementary,
with the smallest footprint) was built before the Town had adopted a Land Use Ordinance; it has no
required stormwater management facilities. Erosion and nutrients are priority pollutants at these sites;
stormwater volume reduction is also a point of emphasis, although more difficult to regulate. Because of
the large amount of Carrboro dedicated to residential land use, homeowners are also a priority audience,
with all target pollutants being relevant. Businesses are an important audience especially in areas with
commercial development near downtown and in several largely retail and office/institutional land uses.
All target pollutants are relevant, with an emphasis on volume and associated erosion and nutrients.

Requirements
Positions shown in bold have primary responsibility. Other key staff are also shown.
4.2 Program Funding and Budget
In accordance with the issued permit, the Town of Carrboro 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 Town of Carrboro created a Stormwater Utility and Stormwater Enterprise Fund in 2017. The Utility
collects revenue through a rate structure approved by the Town Council. All revenue collected is
dedicated to the stormwater program. In FY 20/21, the rate structure has resulted in $1.0M in projected
revenue. This revenue supports both operating and capital program needs; about half of the annual
revenue is budgeted for operating expenses, including personnel, and about half is budgeted for capital
projects and reserves for future stormwater program needs. An analysis was performed in 2019 to
determine program needs, and a rate structure amendment was adopted in 2020 to raise additional
revenue. A Stormwater Utility Manager was hired in late 2017, a Stormwater Specialist in 2018, and a
Stormwater Administrator in 2020 to provide the necessary staffing to implement this SWMP. These staff
are supported by other staff and additional contractual support and other operating and capital funds as a
result of the revenue being received through the Stormwater Enterprise Fund.
The tiered rate structure is defined by impervious area, and applicable to all non-exempt properties with at
least 500 square feet of impervious area. These fees are billed on the annual County Property Tax
Assessment. More information on the rate structure is available at
http://www.townofcarrboro.org/1138/Stormwater-Utility-Rate-Structure .

PART 8: CONSTRUCTION SITE RUNOFF CONTROL PROGRAM
In accordance with 15A NCAC 02H .0153, the MS4name 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.

Training of Orange County Erosion Control staff will be per an agreement, "Memorandum of Agreement
between the NC Sedimentation Control Commission (Commission) and Orange County"
The Town delegated authority to Orange County via a Board of Aldermen resolution in 1976 and
amendment of the Land Use Ordinance in 1983.
During this permit cycle, the Town will increase efforts to coordinate Construction Site Runoff Control
activities with the County. The Town specifically intends to coordinate with Orange County starting in
the first year of the permit and continuing: to review their respective resolutions and ordinances and
amend as warranted; and establish new and enhanced procedures to share information in each
jurisdiction's respective permitting systems.
Orange County Erosion Control has measures in place to review plans, perform inspections, and enforce
as necessary for any and all sediment and erosion control practices for permitted development projects in
Carrboro. Orange County will continue in this permit cycle to provide an annual report to the Town to
support the Town's recordkeeping for this Plan.
The Town of Carrboro will also implement the following BMPs to meet NPDES MS4 Permit
requirements.

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 Carrboro 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 Carrboro 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.

Appendix A:
Memorandum of Understanding for
Clean Water Education Partnership (CWEP) Services
Provided by the Triangle J Council of Governments
(final execution anticipated upon FY 21122 Budget Adoption in June, 2021)
This Memorandum of Understanding by and between the undersigned local government
(Local Government) and the Triangle J Council of Governments (TJCOG) pertains to the
services provided by TJCOG under the Clean Water Education Partnership (CWEP) program.
WITNESSETH:
WHEREAS, CWEP and Local Government stormwater programs have the same basic mission
of providing stormwater outreach and education; and
WHEREAS, CWEP is a program administered by TJCOG that has excelled in providing direct
education and mass media services to its partner communities large and small in multiple
watersheds;
NOW, THEREFORE, the following direct education and mass media services will be provided:
1. CWEP will assist the Local Government with the following education/outreach tasks during
the service term:
a. Provide physical and digital outreach materials for local governments and target
audiences that describe target pollutants and their likely sources and impacts on
water quality
b. Maintain an internet website conveying the CWEP program's messages about
stormwater pollution
c. Make available for download via website outreach materials for target audiences,
and distribute materials at in -person or digital community events
d. Post on social media channels to promote CWEP's key messages
e. Provide unlimited local use and access to original and compiled educational
materials on CWEP program website, to include educational videos, printable and
digital lessons, lesson plans, and other resources useful for educating a variety of
ages and audiences in various settings
f. Coordinate annually with stormwater staff and/or relevant educational contacts (as
requested by the Local Government) to schedule and conduct stormwater education
activities that correlate with NC Essential Science Standards or provide opportunities
for citizen participation which may include stream cleanups, citizen science activities,
DRAFT NCS000450 SWMP
Town of Carrboro

or similar efforts. CWEP will coordinate with the CWEP local government
representative prior to contacting any formal educators in the member jurisdiction.
1.1.1
g. Provide mechanisms on CWEP program website for public input on
stormwater issues
2. CWEP will assist the Local Government with the following mass media services:
1) Coordinate an annual outreach campaign in the form of Public Service Announcements
(PSAs) administered by local service providers, which includes the following:
a. Six animated videos about common target pollutants, their likely sources,
their negative impact on water quality, and best practices for target audiences
likely to have significant stormwater impacts
b. Static and animated banner ads stating the program's message of "Clean Water
Begins with You and Me" with a link to the program website
c. Approximately 12 weeks (as market costs allow) of digital pre -roll videos and
display in -banner advertising
d. Approximately 12 weeks (as market costs allow) of television, cable, and radio
PSAs, spread across popular stations with the aim of reaching a variety of target
audiences, including Spanish -language listeners, network news, and cable
entertainment. CWEP will make an effort to ensure that media reach adequately
covers member's jurisdictions. Additional stations and programs may be
proposed by local media placement companies and approved collectively by
members.
e. Print and digital advertising in Spanish -language newspaper
2) Provide outreach materials for target audiences that describe target pollutants and their
likely sources and impacts on water quality
3) Provide unlimited local use and access of digital media materials for Partner
jurisdictions' use in public buildings, parks, DMV locations, outdoor movies, etc.
4) Promote regional outreach and education events (such as Creek Week) through CWEP
website and social media platforms
Local Governments may use the tasks above to help comply with NPDES MS4 stormwater
education requirements, Jordan Lake Rules and/or Neuse and Tar -Pamlico nutrient strategy
education requirements. The Local Government's signature on this MOU (and MS4 permit
number if applicable) signifies an understanding that any one of the service assignments listed
above may only partially fulfill its education requirements during an audit from NC DEQ.
Accordingly, the Local Government acknowledges that it is ultimately responsible for meeting all
federal and state laws, rules and regulations related thereto. The Local Government permittee
and CWEP share responsibility for determining how specific service objectives can be
cooperatively achieved, with the understanding that CWEP supplements local efforts to comply
DRAFT NCS000450 SWMP
Town of Carrboro
3/10/2021
Page 46

with regulatory requirements. The Local Government is highly encouraged to send one or more
representatives to CWEP's quarterly steering committee meetings to collaborate on strategies.
CWEP will make every reasonable attempt, as permitted by available staffing and supplies, to
independently and proactively address the objectives in the Local Government's community,
and will update the CWEP Local Government representative each quarter to offer opportunities
for discussion and collaboration.
The Local Government agrees to pay TJCOG for the services provided herein based on a fee
schedule adopted by TJCOG, voted on by CWEP Local Governments, and incorporated herein
by reference. The period of performance under, and the term of, this Agreement will begin on July
1, 2021 and will conclude on June 30, 2022. The Local Government reserves the unilateral right
to terminate this Agreement for cause or convenience (in the case of cause, immediately, and in
the case of convenience, upon thirty (30) calendar days' written notice), whereupon CWEP and
TJCOG will only be entitled to prorated compensation for services properly rendered up to the
date of termination.
CWEP will provide an annual report by August 31 after fiscal year end, with local and regional
outreach and education numbers for both mass media and direct education. Interim metrics can
be provided as needed.
IN WITNESS WHEREOF, both the Local Government and TJCOG have caused this Agreement
to be executed by their chief executive officers, all as of the day and year first above written.
