ii I NCDOT NPDES Stormwater Permit No. NCS000250 Annual Report

Executive Summary 2024
This report was prepared and submitted to be compliant with North Carolina Department of
Transportation's (NCDOT's) National Pollutant Discharge Elimination System (NPDES) stormwater
discharge permit (NCS000250) requirement under Part 4.2 of the permit issued May 1, 2022 (Term V
permit).This Annual Report includes an assessment of the activities performed under the permit for the
fiscal year(July 1, 2023—June 30, 2024).This period is also referred to herein as Term V Permit Year 2
(or PY2).
This Annual Report format mimics the general guidance provided by North Carolina Department of the
Environment Quality(NCDEQ) and includes appropriate information to accurately describe the progress,
status, and results of the Department's permitted programs. This Annual Report includes specific annual
reporting metrics identified in NCDOT's updated Transportation Separate Storm Sewer System -
Stormwater Management Plan (TS4SMP), which was submitted to NCDEQ on November 3, 2023, and
approved by NCDEQ on December 18, 2023. Additionally, the report assesses the Department's
compliance with the permit, provides information on the establishment of appropriate legal authorities,
inspections, and enforcement actions where applicable, and includes specific annual reporting metrices
identified in NCDOT's TS4SMP for each permitted program area.The TS4SMP effectively serves as
NCDOT's five-year business plan outlining the major activities to be performed to comply with the
permit along with annual reporting metrics. It is the intent of NCDEQ that the reporting metrics
contained in this Annual Report serve as the basis of future annual reports. Hence, this Annual Report
contains a brief introduction which is then followed by the detailed TS4SMP tabular summary of the
Department's Highway Stormwater Program best management practices (BMPs), measurable goals,
schedule for implementation, and reporting metrics for this permit year, as well as anticipated/planned
program activities for the next three years. NCDOT's self-assessment for PY2 indicates that the
Department was in compliance with the requirements of the TS4SMP.
Highway Stormwater Program staff continued to integrate the Term V permit requirements into the
Department's various permit compliance programs during PY2. As anticipated, most programs only
required minor modifications to existing established programs. However, several permit programs
require significant changes over the course of this five-year permit term. These are detailed in Section 2
of this report.
The NPDES permit authorizes NCDOT to discharge stormwater runoff from general roadways including
weigh stations and tolling facilities, construction activities disturbing greater than one acre, borrow
pits/waste piles, industrial facilities, maintenance and storage facilities, office buildings, rest areas,ferry
terminals and NCDOT-owned railways.Activities conducted by the North Carolina Turnpike Authority,
North Carolina Global TransPark, and 1-77 Mobility Partners are also covered under this permit.The 1-77
Mobility Partners Stormwater Management Program Report is included in Appendix A of this report.
Select Accomplishments for Term V Permit Year 2(July 1,2023—June 30, 2024)
Below are a list of programs required by the permit and a few examples of accomplishments achieved
during this permit year(presented as requirements are arranged in the permit):
III NCDOT NPDES Stormwater Permit No. NCS000250 Annual Report

Executive Summary 2024
• Public Education and Outreach Program—The permit requires NCDOT to provide
educational materials to the traveling public concerning the impacts of stormwater
discharges on surface waters and how the public can reduce pollutants in stormwater
runoff. In this permit year, NCDOT continued to provide educational materials at Rest
Areas/Welcome Centers, Ferry Terminals, and other locations for the traveling public.
Additionally, NCDOT made anti-litter messaging materials for the public, including school-
aged children, available on NCDOT's website, social media platforms, and various in-person
outreach efforts.
• Public Involvement and Participation Program—NCDOT continued to maintain reporting
mechanisms for the public to provide input on stormwater issues during project-specific
public meetings, or through NCDOT's website for reporting littering, illicit discharges, or
illegal dumping observations. NCDOT conducted approximately 42 public meetings across
the state this permit year providing the public an opportunity to discuss stormwater
management issues of interest. NCDOT also continued to provide volunteer opportunities to
support its anti-litter campaign with its Adopt-A-Highway program, Swat-A-Litterbug, and
the biannual Litter Sweep program.
• Illicit Discharge Detection and Elimination Program (IDDEP)—NCDOT has established
procedures for reporting illicit discharges and illegal dumping activities along NCDOT right-
of-way(ROW). In this permit year, NCDOT continued to provide training on identifying and
reporting illicit discharges and illegal dumping and reporting them to NCDEQ or other
appropriate local government agencies for enforcement.
• TS4 Mapping Program—New for the Term V permit, is a requirement to map the
components of the Department's drainage system in select areas of the state.The required
components to be mapped include pipes, catch basins, open channels, outfalls, and flow
direction. Mapping is required in the Phase I municipalities which include: Charlotte,
Winston-Salem, Greensboro, Durham, Raleigh, and Fayetteville. During this permit year
NCDOT initiated the first stage of the TS4 Mapping Project. The project is being
implemented in stages and in partnership with the aforementioned municipalities to
minimize duplicative data collection. In PY2, the TS4 Mapping Project team coordinated and
collected existing geospatial mapping data of stormwater conveyance assets, including
those that may be owned by NCDOT, from the six Phase I municipalities; began evaluating
the data; prepared a Data Summary Report; developed a TS4 Mapping Project Plan to
provide the framework for the management and execution of the TS4 Mapping Project
goals; and prepared a Data Gap Report to identify missing data and determine where
additional data collection and/or field work may be needed. Additionally, using internal
forces, NCDOT made significant progress identifying bridges which directly discharge to
waterbodies within the six Phase I municipalities. The bridge outfall identification initiative is
approximately 45%complete. The TS4 Mapping Project has completed the required BMPs
for PY2 and has begun work on PY3 BMPs.
IV NCDOT NPDES Stormwater Permit No. NCS000250 Annual Report

Executive Summary 2024
• Construction Site Runoff Control Program—NCDOT continues to operate under its
delegated authority granted by the NC Sedimentation Control Committee. NCDOT's
Construction Program continues to review and approve erosion &sediment control (ESC)
plans, implement and maintain standard specifications and project special provisions,
provide guidance on ESC/stormwater issues, perform inspections and monitoring of
construction projects, maintain NCDOT's reclamation process, and provide ESC/stormwater
training materials to contractors/consultants.The following inspections were performed by
Roadside Environmental Unit (REU) Field Operations staff in calendar year 2023 for each
category of land disturbing activity: 3,469 contract construction projects, 94 maintenance
projects, 6 vertical construction projects, 328 bridge maintenance projects, and 66
resurfacing/shoulder reconstruction projects. During this permit year, NCDEQ initiated its
reoccurring annual review of the program with approval of continued program delegation
anticipated in PY3.
• Post-Construction Controls
o BMP Retrofit Program—NCDOT maintains its Retrofit Opportunity Site Selection (ROSS)
database of potential stormwater retrofit locations which is integrated within the
Department's ArcGIS Online portal. In this permit year, NCDOT performed the following
reviews:seven HUC-12s completely reviewed, 530 Retrofit Investigation Areas (RIAs)
desktop reviewed, and 160 ROSS sites identified for field review.The total number of
Retrofit Opportunity Areas statewide maintained in ROSS is 78,665. In addition, 23 BMP
retrofit credits were completed in PY2, with highlights(and partnerships) being the
infiltration chambers in Division 3 (Town of Surf City), permeable pavement installations
in Division 2 (Town of Beaufort), and land conservation in the City of Durham to protect
Falls Lake from additional nutrient loading.
o BMP Toolbox—In this permit year, NCDOT continued work on a major update to the
Department's Stormwater Best Management Practices Toolbox design manual and
associated training materials. Following NCDEQ approval of the updated BMP Toolbox,
the manual will be released for use by the Department and its consulting partners for
project development and permit compliance.
o Post-Construction Stormwater Program—The Department continues to implement the
stormwater treatment requirements outlined in the Post-Construction Stormwater
Program (PCSP) which was updated and approved by NCDEQ in 2022.The PCSP
integrates state and federal stormwater requirements into a single document thereby
serving as a convenient resource for design teams. Also, as required by the permit,
NCDOT developed a standard policy for preparing structural stormwater control
measure (SCM) construction drawings and as-built plans, and maintaining them on file
on its Construction SharePoint site.This new policy will be implemented in the next
permit year.
V NCDOT NPDES Stormwater Permit No. NCS000250 Annual Report

Executive Summary 2024
• Pollution Prevention and Good Housekeeping Programs
o Facilities Operation and Maintenance Program—NCDOT continues to implement and
maintain site-specific Stormwater Pollution Prevention Plans (SPPPs)for non-roadway
facilities. NCDOT staff conducted 30 internal site reviews, provided online and in-person
training to Division staff and contractors, and continued to assist Divisions with SPPP
implementation. Note: New for the Term V permit starting next year(PY3), it is a
requirement to begin analytical monitoring of stormwater discharges at outfalls from
two industrial facilities (North Carolina Global TransPark and the asphalt plant located at
the Washington County Creswell Maintenance Yard).
o Spill Response Program—The permit requires NCDOT to maintain and implement spill
response procedures for its non-roadway facilities. In this permit term, NCDOT
continued to implement its spill prevention and response program and to provide
annual spill response training at its non-roadway facilities. NCDOT continued to
maintain its site-specific Spill Prevention Control and Countermeasure (SPCC) Plans
which are integrated into its SPPPs for its maintenance facilities with bulk oil storage.
o TS4 Operation and Maintenance Program—The permit requires NCDOT to develop and
implement a TS4 operations & maintenance (O&M) program designed to reduce the
discharge of pollutants including particulates, sediment, litter, and debris from the
stormwater conveyance system. In addition to performing inspections and maintenance
of the TS4 during normal operations, NCDOT also performed significant litter and debris
removal activities (see Litter Management) and road sweeping activities. NCDOT
performed roadway sweeping in each Division in PY2, utilizing both NCDOT Forces and
contractors, which resulted in a total of 17,675 lane miles swept. During this permit
year, NCDOT began coordination with Division staff to develop written protocols and to
identify high priority areas within the TS4 O&M program for implementation of BMPs to
reduce pollutants.The protocols will be initiated in phases over the remainder of this
permit term in accordance with the scheduled outlined in NCDOT's TS4SMP.
Documentation by Divisions of TS4 O&M will continue to be important in maintaining
permit compliance.
o SCM Inspection and Maintenance Program—In this permit year, NCDOT continued to
implement its SCM Inspection and Maintenance (I&M) program.This includes REU staff
coordinating with consultants and Division staff in performing SCM inspections,
preparing SCM repair and rehab scopes of work and cost estimate bid packets,
conducting post-repair assessments of SCMs, and providing training to Division staff.
REU and Division Roadside Environmental staff coordinated with contractors and other
Division staff to complete non-routine SCM repairs.
VI NCDOT NPDES Stormwater Permit No. NCS000250 Annual Report

Executive Summary 2024
o Vegetation Management Program—REU continued to coordinate and hold vegetation
management training sessions for Division staff.Throughout the permit year, Division
staff attended various other trainings that offered pesticide recertification credits. REU
also provided NCDA&CS-approved pesticide recertification training, which included
instruction on pesticide recertification requirements, applications, methods, aquatic
subcategory, pesticide handling, and compliance with NPDES pesticide storage facilities.
o Vehicle and Equipment Maintenance Program—NCDOT maintains a well-established
vehicle and equipment preventative maintenance (PM) program for its fleet, which
includes routine PM inspections and service of the Department's facilities,vehicles, and
equipment. Repairs are performed as needed. NCDOT performs the PM inspections and
maintenance based on specific frequencies and schedules for each vehicle/equipment
to maintain them in good operating condition and to prevent and minimize vehicle/
equipment leaks and drips to the ground surface.
o Litter Management Program—NCDOT continues its litter pickup activities including
Adopt-A-Highway, Sponsor-A-Highway, Contract Litter Removal, Litter Sweep, and Swat-
A-Litterbug programs.The Department documents the efforts of its partners,
volunteers, and internal staff on litter collection.The Term V permit requires new
actions such as litter inspections, identification of litter hotspots, and implementation of
BMPs to prevent the discharge of litter at hotspots. These will be focus areas in the
remaining years of this permit term. In CY 2023, and for the consecutive year, NCDOT
and our partner organizations picked up over 11.5 million pounds of litter.
o Fecal Coliform Reduction Program—The permit requires NCDOT to take specific actions
at its non-roadway facilities including connecting on-site wastewater systems to publicly
owned treatment works where feasible, stormwater pollution prevention training of
wastewater facility operators, and maintaining pet waste stations. NCDOT continued to
maintain Pet Waste Stations at its Rest Area/Welcome Center facilities and its Ferry
Terminals. NCDOT also continued to operate and maintain its on-site domestic
wastewater treatment systems at two Rest Areas (1-77 Surry County and 1-40 Haywood
County) in accordance with the manufacturer's and state guidance. Septic systems
located at other NCDOT non-roadway facilities continue to be maintained and evaluated
for connections to public systems.
• TMDL Program—In PY2,there were no new EPA approved TMDLs anywhere in the state,
therefore NCDOT focused its attention on watersheds with existing established TMDLs.The
TMDL Program is supported by a variety of NCDOT programs, each contributing in specific
ways to address the pollutants of concern in TMDL watersheds. For example,the BMP
Retrofit Program plays a crucial role by identifying and implementing retrofit opportunities
in TMDL watersheds.The Facilities Operation and Maintenance Program ensures that
appropriate BMPs and relevant training are in place at NCDOT facilities, specifically targeting
the pollutants identified in TMDLs.The Fecal Coliform Reduction Program focuses on
VII NCDOT NPDES Stormwater Permit No. NCS000250 Annual Report

Executive Summary 2024
managing septic systems and pet waste, particularly at ferry terminals and rest areas,to
reduce fecal coliform levels in the watershed.The IDDEP supports the TMDL Program by
identifying and reporting illicit discharges at non-roadway facilities, thereby reducing
potential sources of pollution. Similarly, the Litter Management Program coordinates
ongoing litter collection efforts within the watershed, which is critical for minimizing trash-
related pollutants.The PCSP implements stormwater management practices in TMDL
watersheds, following a detailed decision support matrix that ensures actions are tailored to
specific needs.The Public Education and Outreach Program and the Public Involvement and
Participation Program enhance the TMDL Program by expanding educational efforts and
increasing public engagement within TMDL watersheds, which helps address potential
pollutant sources.The SCM l&M Program is vital for ensuring that SCMs are maintained to
operate at optimal performance levels. Finally,the TS4 Mapping and Operation and
Maintenance Program supports TMDL compliance by compiling mapping data and
evaluating operational strategies within the watershed.This information is used by the
TMDL program manager to make informed decisions regarding whether additional, targeted
actions are warranted or practicable within TMDL watersheds.
• Research Program—NCDOT completed three stormwater research projects during this
permit term: RP 2019-02 Protocol for Outlet Analysis at Highway Sites, RP 2020-01 Reducing
the Environmental Impact of Road Construction, and RP 2021-04 Evaluating Biochar as a
Multi-Beneficial and Cost-Effective Soil Amendment Option for Maximal Storm water
Infiltration. NCDOT Hydraulics Unit and REU staff continue to assist with the coordination of
multiple ongoing research projects that support NCDOT's Highway Stormwater Program and
its permit requirements.The following are active research projects: RP 2019-07 Evaluating
and Optimization of Engineered Media Amendments for Contaminant Removal in
Storm water Runoff Filtration Systems, RP 2021-02 Evaluating Maintenance Requirements
and Water Quality Benefits of Alternative Vegetated and Non-Vegetated Linings in Roadside

Purpose
This Annual Report was prepared and submitted in compliance with the North Carolina Department of
Transportation's (NCDOT's) statewide National Pollutant Discharge Elimination System (NPDES)
stormwater discharge permit (NCS000250) requirement under Part 4.2 of the permit issued May 1, 2022
(Term V permit). This Annual Report includes an assessment of the various achievements and
compliance activities performed under the permit for the fiscal year(July 1, 2023—June 30, 2024), also
referred to herein as Term V Permit Year 2 (or PY2).
The Report format mimics the general guidance provided by North Carolina Department of the
Environment Quality(NCDEQ) and includes appropriate information to accurately describe the progress,
status, and results of the Department's permitted programs. This Annual Report includes specific annual
reporting metrics identified in NCDOT's updated Transportation Separate Storm Sewer System -
Stormwater Management Plan (TS4SMP), which was submitted to NCDEQ on November 3, 2023, and
approved by NCDEQ on December 18, 2023. This Annual Report assesses the Department's compliance
with our permit, provides information on the establishment of appropriate legal authorities, inspections,
and enforcement actions where applicable, and includes specific annual reporting metrics identified in
NCDOT's TS4SMP for each permitted program area.The TS4SMP effectively serves as NCDOT's five-year
business plan outlining the major activities to be performed to comply with the permit along with
annual reporting metrics. It is the intent of NCDEQ that the reporting metrics contained in this Annual
Report serve as the basis of future annual reports. Hence, this Annual Report contains a brief
introduction (Section 1)which is then followed by the detailed TS4SMP tabular summary(Section 2) of
the Department's Highway Stormwater Program best management practices (BMPs), measurable goals,
schedule for implementation, and reporting metrics for this permit year, as well as anticipated/planned
program activities for remaining years of this permit term. NCDOT's self-assessment for PY2 indicated
that the Department was in compliance with the requirements of the TS4SMP.
Permit Coverage
The Highway Stormwater Program (HSP) was established in 1998 to manage NCDOT's compliance with
its NPDES stormwater permit. Under this NPDES permit NCDOT is authorized to discharge stormwater
from NCDOT's transportation separate storm sewer system (TS4)to surface waters statewide.The Term
V NPDES permit, effective through April 30, 2027, specifically authorizes NCDOT to discharge

Rule Requirements
The following nutrient requirements apply within the Jordan and Falls Lake Watersheds:
1. Outfall Identification. Identify NCDOT stormwater outfalls from Interstate, US, and NC primary
routes.
2. Illegal Discharges. Identify and eliminate illegal discharges into the NCDOT's stormwater conveyance
system.
3. Nutrient Education Program. Implement a Nutrient Management Education Program for NCDOT
staff and contractors engaged in the application of fertilizers on highway ROW.
4. Riparian Buffer Protection. Meet riparian buffer and diffuse flow requirements on new and
widening road projects.
5. Nutrient Targets on Non-Road Development.Achieve sub-watershed specific nutrient reduction
targets on new non-road development projects using the NCDOT Jordan Lake Stormwater Nutrient
Loading Accounting Tool (NCDOT-JLSLAT) or through another calculation method that is acceptable
to NCDWR.
6. Plan to Offset Nutrients from Baseline to Program Implementation. Provide an estimate of, and
plans for offsetting, nutrient load increases from lands developed subsequent to the baseline period
but prior to implementation of the new development program (stayed in the Jordan Lake
Watershed).
7. Nutrient Removal Retrofits. Implement six stormwater retrofit BMPs per year in the Falls Lake
watershed to reduce nutrient loads until NCDOT's existing development load reduction
requirements are achieved, or the lake's designated uses are restored (Falls Lake Watershed only).
Program Overview
The NC Environmental Management Commission (EMC) adopted permanent nutrient management rules
for Jordan Lake and Falls Lake which became effective in 2009 and 2011, respectively. In response,
NCDOT initiated the Guided Reduction of Excess Environmental Nutrients (GREEN) Program to integrate
66 NCDOT NPDES Stormwater Permit No. NCS000250 Annual Report

Program Summaries 12024
and enhance NCDOT's stormwater and nutrient management practices and to support NCDOT's
compliance with the Jordan and Falls Lake Rules.
The Jordan Lake GREEN Program outlines the Department's approach to managing nutrients from new
development, including new and widened roads and new non-road developments. The EMC approved
the Jordan Lake GREEN Program on November 8, 2012. The Rules also include retrofit requirements to
reduce nutrient loads from existing NCDOT development; however, various Session Laws have delayed
this requirement.
The Falls Lake GREEN Program addresses the Department's approach to managing nutrients from new
and existing developments consisting of new and widened roads, new non-road development, and
existing road and non-road development.The EMC approved the Falls Lake GREEN Program on January
9, 2014. Among other things,these regulations require NCDOT to implement new training for staff and
contractors, calculate nutrient loads resulting from projects and devise controls to reduce the increased
loads.A notable requirement of the Falls Lake rules is the mandate for the Department to construct six
retrofits per year in the watershed or implement equivalent nutrient load reduction measures.
Accomplishments
1. Outfall Identification
In previous years NCDOT completed field outfall identification within the Falls and Jordan watershed
from open channel and pipe stormwater conveyances. During PY2, NCDOT added to the outfall
inventory bridges which directly discharge to surface waters within the City limits of Durham and
Greensboro.
2. Illegal Discharges
During PY2, NCDOT maintained and implemented a written IDDE Plan to detect and address illicit
discharges, illegal dumping and any non-stormwater discharges identified as significant contributors of
pollutants to the TS4.Additionally, NCDOT staff conducted 92 dry weather outfall screenings for illicit
discharges.
NCDOT staff and contractors working within the NCDOT ROW report incidences of observed illegal
discharges and NCDOT staff follow up for verification, reporting and resolution. NCDOT utilizes an IDDEP
Field Report for use by Division staff to make sure that the data needed to follow up on the illicit
discharge is obtained.
NCDOT held its state-wide Litter Sweep Program during the last two weeks of September and April.
Residents throughout the state participate in local efforts to help clean up North Carolina's roadways.To
support this effort, NCDOT maintenance crews devote one week of their time to pick up litter and
collect orange bags placed on the roadsides by volunteers.The 2023 Annual Litter Report showcases the
amount of litter collected in each county.
67 NCDOT NPDES Stormwater Permit No. NCS000250 Annual Report

Program Summaries 12024
In addition to the Litter Sweeps, NCDOT continues to provide material support to the Clean Jordan Lake
organization for their litter collection events for Jordan Lake.
3. Nutrient Education Program
NCDOT provides annual training for Vegetation Management personnel, and trains or requires
equivalent training for Vegetation Management contractors.Training includes the following topics:
• Appropriate application of fertilizer and pest control products;
• Proper mowing techniques;
• Storage and handling of landscape material, including fertilizer and pest control products; and
• Avoiding water quality impacts associated with vegetation management.
4. Riparian Buffer Protection
NCDOT complies with all aspects of the Riparian Buffer Protection Rules on its transportation projects,
and has created the following posters to support designers in compliance with both the buffer rules and
NCDOT's PSCP:
1. Maximizing Shoulder Section
2. Adequate Energy Dissipation
3. Utilizing Natural Features and Drainage Pathways
4. Maximizing Vegetative Conveyances
5. Nutrient Targets on Non-Road Development
In PY2, NCDOT did not complete any new non-road projects in the Jordan Lake or Falls Lake watersheds
that would be subject to NSW rules. However, NCDOT has emphasized proper inspection and
maintenance of the existing SCMs on projects in the Jordan Lake and Falls Lake Watersheds (as well as
state-wide). NCDOT uses its SCMS database to track inspection and maintenance of SCMs statewide,
including those located within the Jordan Lake and Falls Lake watersheds. NCDOT Division Roadside
Environmental Engineers maintain SCMs in the Jordan and Falls Lake watersheds.
NCDOT's SCMS database is used to track inspection and maintenance of SCMs statewide, including
those located within the Jordan Lake and Falls Lake watersheds. NCDOT Division Roadside
Environmental Engineers maintain SCMs in the Jordan and Falls Lake watersheds. In this permit year,
there are 13 SCMs (six within Falls Lake watershed and seven within Jordan Lake watershed)that have
significant rehabilitation needs.Ten of these SCMs are scheduled to be repaired and three SCMs are
being evaluated by HSP staff for potential retrofit to improve performance.
For both road and non-road projects, NCDOT's SCM l&M Manual provides guidance to NCDOT staff that
are involved in caring for SCMs. In addition, NCDOT utilizes a PCSP Poster to inform Division offices of
the need to work with the Hydraulics Unit to create a Stormwater Management Plan.

6. Plan to Offset Nutrients from Baseline to Program Implementation
Nutrient Scientific Advisory Board—NCDOT is a member of the Nutrient Science Advisory Board (NSAB).
The NSAB functions primarily as an advisory group to assist and guide NCDEQ with effective
implementation of nutrient management strategies for developed areas as they relate to the Existing
Development rule.The NSAB helps the agency identify management strategies that reduce nutrient
loading from existing development, evaluate management strategies, develop an accounting system,
and identify improvements or refinements needed to modeling and other analytical tools.
Jordan Lake One Water—Jordan Lake One Water(JLOW) is a partnership to facilitate cooperation and
integrated water resource management in the Jordan Lake watershed.The group is comprised of local
governments, state government, conservation groups, universities, water utilities, agriculture, and
private industry stakeholders interested in sharing the cost of water quality and quantity improvements
in order to realize watershed-wide social, economic, and environmental benefits.JLOW activities are
presently being coordinated with the assistance of the Central Pines Regional Council (formally the
Triangle J Council of Governments). NCDOT is a formal member of JLOW and serves on the Board of
Directors. Also,JLOW successfully filed for incorporation as a NC non-profit organization, adopted a set
of bylaws and an ethics policy. In PY2 NCDOT chaired a JLOW Rules Working Group with the goal to
develop Jordan Lake nutrient management strategy rule concepts, in partnership with NCDEQ, to allow
for JLOW activities to support compliance with future Jordan Lake rule requirements.
GREEN Training—NCDOT continues to offer an online training video entitled 'NCDOT JLSLAT Intro to
GREEN Program,'first introduced in 2016, to support staff and contractors when using the NCDOT-
JLSLAT, on new non-road development projects.
7. Nutrient Removal Retrofits(Falls Lake only)
Accomplishments during PY2 include:
• Implemented a 23.6-acre remnant parcel preservation project immediately south of the Beaver
Marsh Nature Preserve, preventing the parcel from being acquired by an adjacent owner and
converted to an industrial use. Using NCDWR's Stormwater Nitrogen and Phosphorus Tool
(SNAP)Tool, NCDOT has calculated that this project removes the equivalent of 15 times as much
Total Nitrogen and Total Phosphorus as a "typical NCDOT retrofit." A typical NCDOT retrofit is
estimated as a bioretention cell with an internal water storage zone designed to treat the runoff
from a one-acre parking lot.Therefore, NCDOT claims 15 Falls Lake Retrofit Credits for this
practice.
• Presented the NCDOT gravel wetland constructed in 2022 at the 2023 National Low Impact
Development (LID) Conference in August 2023 and at the WaterJAM Conference in September
2023.
• Refined the shoulder stabilization practice in which eroded roadside shoulder pull-off areas are
stabilized with geogrids, media and grass that allows for infiltration. In support of this practice,
NCDOT has evaluated available products, materials, and design standards.
69 NCDOT NPDES Stormwater Permit No. NCS000250 Annual Report

Program Summaries 12024
• Identified ten sites for initial shoulder stabilization field evaluations. Based on the field
evaluations, NCDOT will select sites for design and construction.
• Developed standards and estimated performance for implementing reforestation projects to
improve nutrient uptake and reduce flooding.
Considerations for PY3
NCDOT will continue to implement the Department's GREEN Program and achieve requirements set
forth for new and existing (Falls GREEN, only) road and non-road development in the Jordan Lake and
Falls Lake watersheds. NCDOT plans to complete development of gravel wetland design specifications to
be included in NCDOT's BMP Toolbox. NCDOT will continue to play a leadership role in JLOW as the
organization develops the capabilities to serve as a nutrient rule compliance coalition. Additionally,
NCDOT will continue to work cooperatively with NCDEQ as the Jordan and Falls nutrient management
strategies proceed through the rule making process.
