The current iteration of the City permit became effective October 10, 2018 and extends through October 9, 2023. This permit authorizes the City to discharge stormwater from the MS4, located within the City corporate limits, into the receiving waters of the State within the Neuse River Basin. This document is the Stormwater Management Plan (SWMP), as required by Part I.A of the City’s NPDES MS4 permit, which establishes the methods by which the City implements the permit requirements to achieve compliance and protect receiving stream water quality, to the extent allowable under State and local law. In preparing this SWMP, the City of Raleigh has evaluated its MS4 and the permit requirements to develop a comprehensive five-year SWMP that will meet the community’s needs, address local water quality issues, and provide the measures necessary to comply with the permit. This includes the effective prohibition of non-stormwater discharges to the MS4 and the reduction of pollutant discharges to the maximum extent practicable (MEP) through the implementation of the six minimum measures stipulated in the Federal NPDES regulations. This SWMP identifies the program elements to be implemented under the permit program, and includes: a brief program narrative, the best management practices (BMPs) intended to fulfill the permit requirements; measurable program goals; annual reporting metrics; implementation schedules; and responsible parties. The SWMP includes the following core NPDES MS4 permit programs, implemented within the City’s corporate limits unless otherwise noted: • Project Education and Outreach - BMPs to distribute educational materials to the community, conduct public outreach activities, raise public awareness on the causes and impacts of stormwater pollution, and inform the public on steps they can take to reduce or prevent stormwater pollution. • Public Involvement and Participation - BMPs for the public to participate in program development and implementation and to comply with applicable State and local public notice requirements. • Illicit Discharge Detection and Elimination - BMPs to detect and eliminate illicit discharges to the City’s MS4, address significant contributors of pollutants to the MS4, implement appropriate enforcement procedures and actions, maintain a map showing the City’s major MS4 outfalls to State waters receiving discharges, and inform employees, businesses, and the general public of hazards associated with illegal discharges and improper disposal of waste. • Construction Site Runoff Controls - BMPs to reduce pollutants in stormwater runoff from construction activities disturbing one acre or greater of land surface and to provide procedures for public input, sanctions to ensure compliance, requirements for construction site operators to implement appropriate erosion and sediment control City of Raleigh NC - Permit No. NCS000245 Updated February 2021 8 practices, review of site plans, and procedures for site inspection and enforcement of control measures. The City’s unified development ordinance (UDO) exceeds this MS4 permit requirement, requiring BMPs to reduce pollutants in stormwater runoff from construction activities disturbing 12,000 sq ft or more of land surface. The City’s UDO also includes procedures for public input, sanctions to ensure compliance, requirements for construction site operators to implement appropriate erosion and sediment control practices, review of site plans, and procedures for site inspection and enforcement of control measures. This City program is authorized within the corporate limits and the Extra Territorial Jurisdiction (ETJ) area. • Post-Construction Site Runoff Controls - BMPs to manage stormwater runoff from development that drains to the City’s MS4, to provide a mechanism requiring long -term operation and maintenance of BMPs, and to ensure controls are in place to minimize water quality impacts. This City program is authorized within the corporate limits and the ETJ. • Pollution Prevention and Good Housekeeping for Municipal Operations - BMPs to prevent or reduce stormwater pollution from municipal operations through pollution prevention and good housekeeping techniques. • Program to Monitor and Evaluate Stormwater Discharges to Municipal Systems – BMPs to monitor and control pollutants in stormwater discharges to the City’s MS4 from hazardous waste treatment, storage, disposal, and recovery facilities, and from industrial facilities subject to Section 313 of Title III of the Superfund Amendments and Reauthorization Act of 1986 (SARA), and from industrial facilities the City determines are contributing or have a potential to contribute substantial pollutant loading to the municipal stormwater system. • Water Quality Assessment and Monitoring - BMPs to evaluate the impacts on water quality through the implementation of a water quality assessment and monitoring plan. • Total Maximum Daily Loads (TMDLs) - BMPs to evaluate strategies and tailor practices to address pollutants of concern in TMDL-listed streams. The SWMP will be evaluated annually and updated, if necessary, throughout the permit reporting period to ensure that the elements and minimum measures it contains continue to adequately provide for permit compliance and the community’s needs. Upon approval of updates to the SWMP 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. City of Raleigh NC - Permit No. NCS000245 Updated February 2021 9 Section 2: MS4 Information The following sections include general information about the City’s administrative organization, the storm sewer system, and the MS4 receiving waters. These sections inform the development of the stormwater program and successful permit program implementation. 2.1 Permitted MS4 Area This SWMP applies throughout the corporate limits of the City, including all regulated activities associated with the discharge of stormwater from the MS4. Additionally, the City is authorized to operate, administer, and enforce the construction site runoff control and post construction site runoff control programs within the ETJ. The map below (Figure 1) shows the corporate limits and the ETJ area of the City as of the date of this document. Figure 1. City of Raleigh Corporate Limits and ETJ City of Raleigh NC - Permit No. NCS000245 Updated February 2021 10 2.2 Existing MS4 Mapping In fiscal year 2014, the City conducted an MS4 mapping program which compiled and documented all known MS4 infrastructure and outfalls within the City corporate limit and ETJ in a geographic information system (GIS). Since this initial effort, the City has continually updated the MS4 mapping, which includes pipes, ditches, inlets, catch basins, culverts, headwalls, channels, manholes, and outfalls, including sizes and inverts. The MS4 mapping updates are incorporated into the illicit discharge detection and elimination program, which is described in Section 6. The condition of the MS4 stormwater inlets and conveyance system are evaluated by the City storm sewer system inspection and maintenance program, which is described in Section 9. 2.3 Receiving Waters The City MS4 is located within the Neuse River Basin and discharges directly into receiving waters as listed in Table 1 below. Applicable water quality standards listed below were compiled from the following North Carolina Department of Environmental Quality (DEQ) sources; Waterbody Classification Map (https://ncdenr.maps.arcgis.com/apps/webappviewer/index.html?id=6e125ad7628f494694e25 9c80dd64265) and the most recent EPA-approved DEQ Final 303(d) List (2018) (https://files.nc.gov/ncdeq/Water%20Quality/Planning/TMDL/303d/2018/2018 -NC-303-d--List- Final.pdf). TMDLs are addressed in Section 2.5 and Section 12. The water quality classifications referenced in Table 1 include: • B: Primary Recreation, Fresh Water • C: Aquatic Life, Secondary Recreation, Fresh Water • CA: Critical Area • NSW: Nutrient Sensitive Waters • WS-III: Water Supply III – Moderately Developed • WS-IV: Water Supply IV – Highly Developed Table 1.

The City will provide annual program target pollutants and results in the City’s annual reporting, as documented in Section 13. City of Raleigh NC - Permit No. NCS000245 Updated February 2021 17 Section 3: Program Implementation The section corresponds to Part II Section A of the MS4 permit. The City’s program organization and funding are necessary elements for implementing the remaining elements of MS4 program. Annual reporting metrics are included in Table 4. 3.1 City Ordinances The current City regulations, ordinances, policies, and procedures can be accessed on the City website at: https://raleighnc.gov/services/government/city-code and https://raleighnc.gov/business/content/PlanDev/Articles/Zoning/ZoningRemapping.html. 3.2 Program Funding and Budget In accordance with the MS4 permit, the City maintains adequate funding to implement and manage the provisions of the SWMP and comply with the permit requirements. Multiple sources of funding are utilized by the responsible parties to achieve permit compliance. Program elements are primarily funded by the City stormwater utility fee. Additional sources of funding include plan review and permit application fees, and the City general fund may be utilized for pollution prevention and good housekeeping activities by owning departments. Further fiscal analysis and investigation of funding options (such as a general fund allocation or a change to the stormwater fee) will be conducted annually to maintain adequate funds to meet program needs. 3.3 Organizational Structure The City MS4 program is implemented by multiple departments with oversight and coordination led by the Stormwater Management Division, which is within the Engineering Services Department. The responsible parties are identified in organizational charts, Figures 2 and 3. These charts depict responsible parties for MS4 permit implementation and do not reflect the entire City organizational structure. The responsible parties also are identified by program element and BMP in Sections 4 through 12. Some responsible departments have been identified for having a direct role in implementing the SWMP, such as the SCM Program, and others have an ancillary role (i.e., implement pollution prevention and good housekeeping practices or provide program support activities, such as Information Technology).

The City is not expected to attain the water quality standards for the subject receiving waters. The TMDLs identified within the City are documented in Section 2.5 and Table 2. The Falls Lake TMDL is being addressed through the City’s participation in the Upper Neuse River Basin Association. As documented in Section 8, the Neuse River Estuary is a Nutrient Sensitive Water, so the City addresses this TMDL through the implementation of the Nutrient Sensitive Waters Management Strategy. The Pigeon House Branch and Perry Creek TMDL are local TMDLs without individual numeric WLAs assigned to the City. Implementation of TMDLs, such as Pigeon House Branch and Perry Creek, are achieved through the application of a variety of BMPs detailed in Table 13 for TMDLs with an individual numeric WLA or the program elements in Table 14 for other TMDLs within the corporate limits.
