NCDOT NPDES TS4 PERMIT NCS000250
July 2021
1. Introduction
The purpose of this Stormwater Management Plan (TS4SMP) is to establish and define the means by
which the North Carolina Department of Transportation (NCDOT) will comply with its National Pollutant
Discharge Elimination System (NPDES) Transportation Separate Storm Sewer System (TS4) 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 TS4SMP identifies the specific elements and minimum measures that NCDOT 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 TS4
Permit number NCS000250, as issued by NCDEQ. This permit covers activities associated with the
discharge of stormwater from the TS4 as owned and operated by and located within the rights of way
(ROWs) of the NCDOT transportation systems.
In preparing this TS4SMP, NCDOT has evaluated its TS4 and the permit requirements to develop a
comprehensive 5-year TS4SMP that will meet NCDOT’s needs, address water quality issues and provide
the minimum measures necessary to comply with the permit. The TS4SMP will be evaluated and
updated annually to ensure that the elements and minimum measures it contains continue to
adequately provide for permit compliance and NCDOT’s needs.
Once the TS4SMP is approved by NCDEQ, all provisions contained and referenced in this TS4SMP, along
with any approved modifications of the TS4SMP, are incorporated by reference into the permit and
become enforceable parts of the permit. Any major changes to the approved TS4SMP will require
resubmittal, review and approval by NCDEQ, and may require a new public comment period depending
on the nature of the changes.

3 1. TS4 Information
3.1 Permitted TS4 Area
This TS4SMP applies to the discharge of borrow pit wastewater and stormwater from construction
activities and the NCDOT TS4 located statewide, including all regulated activities associated with the
discharge of stormwater from the MS4.
3.2 Existing TS4 Outfall Mapping Program
The current TS4 Outfall Mapping Program includes explicit and implicit stormwater outfalls and Waters
of the United States. Selected watersheds where an explicit inventory has been performed may have
additional data collected.
NCDOT maintains a map of implicit and explicit outfall inventories. Status of the mapping program is
provided in the table below.
Table 3-1: Outfalls Inventoried Through PY2020 (as of July 2020)
Outfall Type Total Outfalls in Inventory
Implicit Roadway Outfalls 116,087
Explicit Roadway Outfalls 1,873
Explicit Non-Roadway Facility with TS4
Operations Outfalls and Non-Roadway
Industrial Facility Outfalls
665

3.3 Receiving Waters
The NCDOT TS4 encompasses the entire state of North Carolina and is located within all River Basin. The
NCDOT TS4 encompasses the entire state of North Carolina and is located within all River Basins.
Applicable water quality standards can be found at the following NCDEQ sources:
o Waterbody Classification Map
o Impaired Waters and TMDL Map
o Most recent NCDEQ Final 303(d) List
The NCDOT TS4 is interconnected with other regulated MS4s and directly receives and discharges
stormwater to these systems.
3.4 Total Maximum Daily Loads
The Total Maximum Daily Loads (TMDLs) listed in Table 3-2 below have identified NCDOT as a significant
contributor and assigned NCDOT a unique Waste Load Allocation (WLA) . The table also indicates
whether a Report of Findings has been approved by DEMLR.

3.5 Endangered and Threatened Species and Critical Habitat
Significant populations of threatened or endangered species and/or critical habitat have been identified
within the regulated TS4 area. NCDOT performs site-specific assessments for threatened or endangered
species for each construction project. Table 3-3 summarizes examples of species that may be
significantly impacted by the quality of surface waters within their habitat, but is not intended to be an
exhaustive list of endangered or threatened species.

bats Bat Threatened
3.6 Non-Stormwater Discharges
The water quality impacts of non-stormwater discharges have been evaluated by NCDOT at NCDOT non-
roadway facilities as summarized in Table 3-4 below. The unpermitted non-stormwater flows listed as
incidental do not significantly impact water quality. NCDOT believes residential and charity car washing
and street washing may have a possible significant water quality impact.
Street washing discharges are addressed under the Litter Management Program in Part 10 of this
TS4SMP. The Division has not required that other non-stormwater flows be specifically controlled by
the NCDOT.
Wash water associated with car washing that does not contain detergents or does not discharge directly
into the TS4 is considered incidental. Vehicle and equipment washing with detergents is directed to a
wastewater treatment system, local Publicly Owned Treatment Works (POTW), collected for treatment
or recycling, or permitted by another NPDES permit, or other equivalent measure; or if sanitary sewer is
not available then performed on a grassed or graveled area to prevent point source discharges of
washwater into storm drains or surface waters. Detergents used are biodegradable with pH adjusted to
be in the range of 6 to 9 standard units.

4 Stormwater Management Program Administration
4.1 Organizational Structure
NCDOT’s Highway Stormwater Program (HSP) is collaboratively managed by NCDOT’s Hydraulics Unit
(HU) and Roadside Environmental Unit (REU) with support from others including NCDOT’s consultant
partners, Division personnel, and Research & Development staff and researchers (see Figure 4-1).
NCDOT’s primary HSP consultant, AECOM Technical Services (AECOM), assists with HSP program
planning and implementation. Other HSP consultants provide support for various HSP permit programs.
Additional NCDOT business units and sub-consultants are incorporated as needed to address unique
project tasks or workloads. The HSP consultants facilitate a significant portion of the development of
guidance documents and training material under the oversight of the HSP staff.
Figure 4-1. HSP Collaborative Management Organization

The HSP also receives in-field implementation support from other NCDOT staff, making it a Department-
wide initiative (See Table 4-1). With a few exceptions, the different program areas of the HSP shown in
Table 4-1 effectively mirror the NPDES Permit sections. Each program area is led by technical staff in the
business unit having the most responsibility and authority to implement the requirements, with support
and implementation from other business units. Table 4-1 indicates the primary, supporting, and
implementing business units by the respective P, S, and I letters in the matrix. A separate list of
responsible positions is maintained by NCDOT.

8 Construction Site Runoff Control Program
In accordance with 15A NCAC 02H .0153, NCDOT 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 (See Table 8-1). 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 delegated to NCDOT. Projects performed by others under a project-specific agreement with NCDOT
to provide erosion and sediment control activities are also covered under this permit.

Construction Program Conformance with NCG010000
NCDOT has a robust Construction Program that governs development activities disturbing one or more
acres of land surface by Department personnel or contractors. As required in Section C.1.b NCDOT’s
NPDES permit, the Department has adopted appropriate elements from the statewide General Permit
No. NCG010000 for “Construction Activities that are also Subject to the North Carolina Sediment and
Pollution Control Act of 1973.” NCDOT’s program conforms to applicable portions of issued NCG010000
dated April 1, 2019. A few key variations from NCG010000 are described below. The variations
generally relate to NCDOT’s role as a delegated authority, in terms of reporting to DEMLR.
NCDOT develops a project-specific erosion and sediment control (ESC) plan adhering to the applicable
requirements of the NCG010000 permit, the NC Sediment Pollution Control Act and 15A NCAC 04B
.0101-.0132. These plans are not submitted to DEMLR; rather, NCDOT serves as the reviewing and plan
approval agency. NCDOT tracks proposed regulated activities using its ERCON database and lists all
ongoing construction projects on its public website NCDOT.gov via a Construction Progress Report
database instead of the NCG010000 certificate of coverage and electronic Notice of Intent (NOI)
process. NCDOT maintains this roster of all construction projects and their status, including projects
disturbing over one acre.
ESC plans developed include location information, general site features such as property lines, project
limits, site drainage features, existing and proposed facilities and other features similar to the NCG01000
guidelines. The plans, detail drawings, and project special provisions also feature locations of the
temporary and permanent ESC measures and specifications for ground and vegetative stabilization.
Calculations for peak discharges of runoff from each outlet and other design calculations are contained
in the master project ESC files. The plans do not contain contact information for the person responsible
for maintenance, as this is generally achieved using Department resources consistent with the NCDOT
Standard Specifications and NCDOT Erosion and Sediment Control Design and Construction Manual.
They also do not include design calculations for culverts and storm sewers and discharge and velocity
calculations for ditch flows as these are housed in NCDOT Hydraulics Unit master project files.
Documentation under Part II, Section A( 8) of the NCG010000 permit, other than required 404/401
permits, is not relevant to the NCDOT program and is not included.
The design standards presented in the NCG01000 permit are incorporated into the NCDOT Erosion and
Sediment Control Design and Construction Manual. NCDOT also complies with the rules on buffer,
ground stabilization, and materials handling in the NCG010000 permit. Consistent with other elements
of its reporting protocol, NCDOT reports bypasses of ESC measures or oil spills to NCDEQ when
impacting jurisdictional waters or private property. NCDOT conforms with the self-inspection
requirements, including maintaining a rain gauge or alternative device, inspecting ESC measures after a
qualifying rain event and inspecting stormwater outfalls and the site perimeter. NCDOT has obtained
permission from DEMLR to use the Multi-sensor Precipitation Estimates (MPE) hosted by the State
Climate Office in lieu of rain gauges for remote site locations. The MPE combines radar-based
precipitation estimates with hourly surface gages to develop a higher-accuracy precipitation dataset and
has been validated and applied successfully by NCDOT for many years. Additionally, NCDOT has some
exceptions to NCG010000’s standard monitoring requirements, which are listed on NCDOT’s Self-
Inspection form.

10 Pollution Prevention and Good Housekeeping Programs
This TS4SMP provides a comprehensive pollution prevention and good housekeeping strategy for
NCDOT’s 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 TS4 operations such as rest area maintenance, fleet and
building maintenance, new construction and land disturbances, and transportation storm sewer system
maintenance. Pollution prevention and good housekeeping for municipal operations includes the
following programs:
• TS4 Facilities Operation and Maintenance Program
• TS4 Spill Response Program
• TS4 Operation and Maintenance Program
• TS4 SCM Operation and Maintenance Program
• TS4 Pesticide, Herbicide and Fertilizer Management Program
• TS4 Vehicle and Equipment Maintenance Program
• TS4 Litter Management Program
NCDOT will manage, implement and report the pollution prevention and good housekeeping BMPs as
specified in Table 10-1 through Table 10-8 below for each required program.

Inventory that have the potential to discharge the TMDL pollutant of concern into the impaired
segments, to their tributaries, and to segments and tributaries within the watershed
contributing to the impaired segments.
2. An Assessment & Monitoring Plan (“Plan”). The Plan shall include an evaluation of the need for
additional data collection related to NCDOT’s discharge of the TMDL pollutant of concern.
Additional data collection to be evaluated may include (but does not require) a supplemental
inventory of NCDOT outfalls, monitoring, an assessment of the effectiveness of existing BMPs,
and an assessment of non-NCDOT discharges entering NCDOT’s conveyance system and
negatively impacting the quality of NCDOT stormwater discharge. If the Plan proposes analytical
monitoring, then it shall include a description of the sample types, frequency, and seasonal
considerations, if applicable. Where appropriate, NCDOT may identify outfalls substantially
similar to other outfalls to reduce the number of outfalls sampled. The Plan may be adjusted as
additional outfalls are identified. The Plan shall include a schedule for implementing the
proposed assessment and monitoring activities.

discuss BMPs to reduce the load to the maximum extent practicable. The ROF shall include a
schedule for implementing the BMPs and define the compliance end point.
6. Upon approval by DEMLR, NCDOT shall implement any approved BMPs in accordance with the
schedule. If written approval of the ROF is not received within 6 months of submittal, NCDOT
will assume it is approved and once implemented, NCDOT will be considered compliant with the
