II NCDOT NPDES Stormwater Permit No. NCS000250 Annual Report Executive Summary 2023 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, 2022—June 30, 2023).This period is also referred to herein as Term V Permit Year 1 (or PY1). This Annual Report follows a new format that 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 Transportation Separate Storm Sewer System -Stormwater Management Plan (TS4SMP)which was submitted to NCDEQ on July 29, 2022. 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 four years. NCDOT's self-assessment for PY1 indicates that the Department was in compliance with the requirements of the TS4SMP. Highway Stormwater Program staff have integrated the new permit changes into the Department's various permit compliance programs during this permit term. As anticipated, most programs have remained substantially similar to existing programs. However, several permit programs will 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, office buildings, rest areas, and NCDOT-owned railways. Activities conducted by the North Carolina Turnpike Authority 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 1 (July 1, 2022—June 30, 2023) Below are a list of programs required by the permit and a few examples of accomplishments achieved during this permit year: III NCDOT NPDES Stormwater Permit No. NCS000250 Annual Report Executive Summary 2023 • 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 as well as by making anti-litter messaging materials for the public including school-aged children available on NCDOT's website,via social media platforms, and various in-person outreach efforts. Examples of such outreach efforts included classroom instruction to elementary school students at Hilburn Academy and participation in the Our Creeks, Our Communities festival celebrating the Walnut Creek Watershed Urban Waters Federal Partnership. • 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 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—NCDOT has established procedures for reporting illicit discharges and illegal dumping activities along NCDOT rights-of-way. In this permit year, NCDOT continues 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/Cumberland Co area. During this permit year, NCDOT began coordination with consultant partners to initiate the development of a five-year compliance plan.The plan will be initiated in phases and in partnership with the aforementioned municipalities to minimize duplicative data collection. • 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 REU Field Operations staff in calendar year 2022 for each category of land disturbing activity: 3,396 contract construction projects, 132 maintenance projects, 9 vertical construction projects, 331 bridge maintenance projects, and 90 resurfacing/shoulder IV NCDOT NPDES Stormwater Permit No. NCS000250 Annual Report Executive Summary 2023 reconstruction projects. During this permit year, NCDEQ initiated its reoccurring annual review of the program with approval of continued program delegation anticipated in permit year 2. • 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 field screenings of 38 sites and found that 23 of these sites were potentially feasible for retrofit. Additionally, program representatives have partnered with several local governments in Wake County to identify potential retrofit locations in compliance with the Complete 540 settlement agreement item#6. 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. 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 last year and approved by NCDEQ.The PCSP integrates state and federal stormwater requirements into a single document thereby serving as a convenient resource for design teams. • 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) at 204 non- roadway facilities. NCDOT staff conducted 17 internal site reviews, provided online and in-person training to Division staff and contractors, and continued to assist Divisions with SPPP implementation. 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 V NCDOT NPDES Stormwater Permit No. NCS000250 Annual Report Executive Summary 2023 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. In this permit year, NCDOT Divisions 1-7 and 9-14 performed road sweeping operations where 12,753 lane miles were swept in selected areas.The Department is required to identify high-priority areas for implementation of BMPs to reduce pollutants, so documentation by Divisions of TS4 O&M will continue to be important in maintaining permit compliance. o Stormwater Control Measure(SCM) Inspection and Maintenance Program—In this permit year, NCDOT continued to implement its SCM inspection and maintenance program.This includes Roadside Environmental Unit staff coordinating with consultants and Division staff in performing SCM inspections, preparing repair and rehab scopes of work and cost estimate bid packets for SCMs that were not functioning as intended, and providing training to Division staff. Division Roadside Environmental staff coordinated with contractors and other Division staff to complete the non-routine SCM repairs. Additionally,the SCM I&M Manual was updated during this permit year. o Vegetation Management Program—Central Roadside 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. Central Roadside also provided NCDA&CS-approved pesticide recertification training, including discussions of 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. NCDOT HSP staff performed an internal review of NCDOT's PM program during this permit year to document any recent changes or updates to NCDOT's PM program. 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 new Term V permit requires some new actions such as litter inspections, identification of litter hotspots, and implementation of BMPs to prevent the discharge of litter at hotspots. In CY 2022, NCDOT and our partner organizations picked up over 11.5 million pounds of litter. VI NCDOT NPDES Stormwater Permit No. NCS000250 Annual Report Executive Summary 2023 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 255 Pet Waste Stations at its Rest Areas/Welcome Centers and Ferry Terminals. Central Roadside continued to operate and maintain its on-site domestic wastewater treatment systems at two Rest Areas 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—The Term V permit provides greater flexibility for how NCDOT complies with EPA-approved total maximum daily loads (TMDLs) but greatly expands the number of TMDL waters NCDOT must respond to by encompassing all TMDLs developed in North Carolina, regardless of whether the TMDL identifies NCDOT as a significant contributor of the pollutant of concern and assigns a unique wasteload allocation to the Department. • Research Program—NCDOT continued managing multiple ongoing stormwater-related research projects. NCDOT neared completion of two reports this permit term: RP 2019-07 Evaluation and Optimization of Engineered Media Amendments for Containment Removal in Storm water runoff infiltration and RP 2019-02 Protocol for Outlet Analysis at Highway Sites.

The Report follows a new format that 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 Transportation Separate Storm Sewer System -Stormwater Management Plan (TS4SMP) which was submitted to NCDEQ on July 29, 2022. 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 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 (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 the next four years. NCDOT's self-assessment for PY1 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 stormwater runoff from the following activities: • General roadway including weigh stations and tolling facilities • General railway • Construction activities disturbing one acre or more • Borrow pits/waste piles including mines • Non-roadway facilities with the following TS4 operations: o Road and bridge maintenance o Vehicle and equipment maintenance 1 NCDOT NPDES Stormwater Permit No. NCS000250 Annual Report Introduction 12023 o Pesticide and fertilizer storage o Salt and deicing chemical storage o Traffic services o Material storage areas o Ferry terminals and maintenance areas o Rail maintenance o Rest areas o Administrative buildings • Non-roadway industrial activities, including: o NC Global TransPark(airport activities) o Asphalt plants owned and operated by NCDOT o NCDOT Mann's Harbor State Shipyard (boat repair activities) o NCDOT Railcar& locomotive Maintenance Facilities (railcar repair activities) This permit also covers the following sub-organizations: • All similar activities of the North Carolina Turnpike Authority (NCTA),for all NCTA projects across the state. • All similar activities of the 1-77 Mobility Partners, for the 1-77 corridor. This permit does not cover the activities of the NC Ports Authority which holds separate NPDES stormwater permits. NCDOT's TS4 is distributed across the entire state of North Carolina (NC) including within all 17 major NC River Basins.The NCDOT TS4 is interconnected with other regulated municipal separate storm sewer systems(MS4s) and directly receives and discharges stormwater from and to these systems. Additional Non-NPDES Stormwater Regulations The HSP also manages NCDOT's implementation of the stormwater requirements in the Jordan and Falls Reservoir watersheds in compliance with state nutrient load reduction rules for state and federal entities. Annual reporting requirements for these two watersheds can be found in Section 3 of this report and is allowed by 15A North Carolina Administration Code (NCAC) 02B .0271 (8)(c) and 15A NCAC 02B .0281 (11)(d). Highway Stormwater Program Organization To implement its NPDES permit, NCDOT has organized the HSP into specific program areas to follow United States Environmental Protection Agency(USEPA) and North Carolina Department of Environmental Quality(NCDEQ)guidance and to effectively address the permit. NCDOT's 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 HSP Organization below). 2 NCDOT NPDES Stormwater Permit No. NCS000250 Annual Report Introduction 12023 Highway Stormwater Program NCDEQ Hydraulics Roadside Unit Environmental Unit NCDOT Research& NCDOTgroups including: Consultants Development • Highway Divisions • Ferry Division • Rail Division • Global Trans Park • Turnpike Authority 1-77 Mobility Researchers • Other Units Partners Shared Compliance Responsibility NCDOT will share the responsibility to implement its permit requirements with 1-77 Mobility Partners for the specified areas of NCDOT's TS4,which are at least as stringent as the corresponding NPDES TS4 Permit requirement. NCDOT remains responsible for compliance if the other entity fails to perform the permit obligation and may be subject to enforcement action if neither NCDOT nor the other entity fully performs the permit obligation. 1-77 MP is responsible for implementing specific BMPs or permit requirements. A legal agreement to share responsibility is in place. There are no other entities applying for co-permittee status under the NPDES TS4 permit number NCS000250 for NCDOT. 3 NCDOT NPDES Stormwater Permit No. NCS000250 Annual Report Program Summaries 2023 2.0 Program Summaries This section summarizes NCDOT's TS4SMP Program Area BMPs, measurable goals, scheduled for implementation, annual reporting metrics, and related reporting comments.

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. 61 NCDOT NPDES Stormwater Permit No. NCS000250 Annual Report Program Summaries 12023 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 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 Falls Lake- In this permit year NCDOT visually monitored the stormwater gravel wetland constructed in 2022 for vegetation establishment and clogging issues. Vegetation was well established by June 2023, and no clogging issues were observed as is a potential concern with these types of devices in early establishment. NCDOT is developing gravel wetland design specifications to be included in NCDOT's BMP Toolbox. NCDOT is also pursuing research funding to perform analytical monitoring on the gravel wetland as this is NCDOT's first constructed gravel wetland and one of only a handful known to existing in the state. NCDOT conducted a design workshop and field visit for NCDOT Hydraulics Unit design staff in March 2023. Abstracts to present on the gravel wetland were submitted and accepted for presentation at the 2023 National LID Conference and WaterJAM 2023. In 2022 NCDOT completed a Nature-base Stormwater Solutions (NBSS)Action Plan for the Falls Lake watershed.The NBSS Action Plan includes a detailed desktop and field search for NBSS retrofit opportunities.The NBSS Action Plan focuses on the use of remnant NCDOT parcels to treat runoff and reduce nutrient loads to the watershed. Soil improvement BMPs were identified as potential practices for implementation. In this permit year NCDOT completed the carbon footprint analysis,which found, in general, NBSS's which minimize the need for significant grading, concrete components, and hauling construction materials, had a lower carbon footprint compared to traditional stormwater BMP construction. In this permit year NCDOT began work to identify sites to install stabilized roadside infiltration zones. Stabilized roadside infiltration zones involve conversion of eroded roadside shoulder pull-off areas in 62 I NCDOT NPDES Stormwater Permit No. NCS000250 Annual Report Program Summaries 12023 stabilized vegetated infiltration zones.These eroded roadside shoulder pull-off areas are typically highly compacted with minimal infiltration. In support of this practice, NCDOT has completed the evaluation of available products, materials, and design standards. NCDOT has also identified numerous potential sites for implementation. From these, ten sites have been selected for initial field evaluations.—NCDOT will be selecting sites for stabilization practice from field evaluations and scheduling for design and construction. 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 Triangle J Council of Governments. In this permit year NCDOT became a formal member ofJLOW and serves on the initial 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 will be leading a JLOW working group 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 online training videos,first introduced in 2016,to support staff and contractors when using the NCDOT nutrient accounting tool, NCDOT Jordan Lake Stormwater Nutrient Loading Accounting Tool (NCDOT-JLSLAT), on new non-road development projects.These videos are available on the NCDOT YouTube channel. In PY2 Jordan and Falls Lake rule requirement refresher training is planned for staff in NCDOT's Facilities Management Unit who coordinate delivery of most non-road development projects. New Non-Road Development Projects—In this permit year NCDOT did not complete any new projects in the Jordan Lake or Falls Lake watersheds that would be subject to the non-road development rules. Litter Removal Support- In addition to its state-wide litter abatement programs, as noted in the BMPs for Public Involvement and Participation, and Litter Management section of this report, NCDOT continues to provide material support to the Clean Jordan Lake organization for their litter collection events for Jordan Lake. Rehabilitation of Existing Stormwater Controls- 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, one SCM (dry detention basin) located within the Falls Lake watershed that had been damaged from a vehicular collision was repaired in August 2022 and now functions as designed. Additionally, nine SCMs (five within Falls Lake watershed and four within Jordan Lake watershed) have significant rehabilitation needs.
