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.

FINAL NCS000450 SWMP Town of Carrboro 10/4/2021 Page 3 PART 3: MS4 INFORMATION 3.1 Permitted MS4 Area This SWMP applies throughout the corporate limits of the Town of Carrboro, including all regulated activities associated with the discharge of stormwater from the MS4. The map below shows the corporate limits of Town of Carrboro as of the date of this document. FINAL NCS000450 SWMP Town of Carrboro 10/4/2021 Page 4 3.2 Existing MS4 Mapping FINAL NCS000450 SWMP Town of Carrboro 10/4/2021 Page 5 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. 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. Table 1: Summary of Current MS4 Mapping Percent of MS4 Area Mapped 100 % No. of Major Outfalls* Mapped 18 total *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. 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: o Waterbody Classification Map o Impaired Waters and TMDL Map o Most recent NCDEQ Final 303(d) List FINAL NCS000450 SWMP Town of Carrboro 10/4/2021 Page 6 Table 2: Summary of MS4 Receiving Waters Receiving Water Name Stream Index / AU Number Water Quality Classification 303(d) Listed Parameter(s) of Interest; Integrated Report Classification; Listing Date Within MS4 Bolin Creek 16-41-1-15-1- (0.5)a WS-V-NSW Mercury/fish tissue; 4t; 2012 (Jordan Lake) Bolin Creek 16-41-1-15-1- (0.5)b WS-V-NSW Mercury/fish tissue; 4t; 2012; Benthos/aquatic life; 5; 2009; (Jordan Lake) Morgan Creek 16-41-2-(5) WS-V; NSW (Jordan Lake) Morgan Creek 16-41-2-(1) WS-II; HQW;NSW Mercury/fish tissue; 4t; 2012 (Jordan Lake) Morgan Creek (University Lake) 16-41-2-(1.5) WS-II; HQW;NSW Chlorophyll a, nitrogen, phosphorus; Mercury/fish tissue; 4t; 2012 (Jordan Lake) Jones Creek 16-41-1-15-1-1 WS-V; NSW (Jordan Lake) Buckhorn Branch 16-41-1-15-1-1-1 WS-V; NSW (Jordan Lake) Jolly Branch 16-41-1-15-1-2 WS-V; NSW (Jordan Lake) Tanbark Branch 16-41-1-15-1-3 WS-V; NSW (Jordan Lake) Immediately Downstream of MS4 Bolin Creek 16-41-1-15-1-(4) WS-IV-NSW Mercury/fish tissue; 4t; 2012; Benthos/aquatic life; 5 ; (Jordan Lake) Morgan Creek 16-41-2-(5.5)a* WS-IV-NSW Mercury/fish tissue; 4t; 2012 (Jordan Lake) Note for all Jordan Lake listings: the parameters of interest include Chlorophyll a, nitrogen, phosphorus, total suspended solids, turbidity, and mercury (fish tissue). Note that the source of mercury is atmospheric emissions; the MS4 program therefore does not identify it as a priority pollutant. *The next most downstream segment below the shown AU of Morgan Creek is also listed for 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. FINAL NCS000450 SWMP Town of Carrboro 10/4/2021 Page 7 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. Table 3: Summary of Approved TMDLs Water Body Name TMDL Pollutant(s) of Concern Stormwater Waste Load Allocation (Y/N) Water Quality Recovery Program (Y/N) Jordan Lake Chlorophyll a, nitrogen, phosphorus, total suspended solids, turbidity N N 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. FINAL NCS000450 SWMP Town of Carrboro 10/4/2021 Page 8 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 summarizes the species that may be significantly impacted by the quality of surface waters within their habitat. Table 4: Potential Federally Listed Species/Habitat Impacted by Surface Water Quality Scientific Name Common name Species Group Federal Listing Status Fusconaia masoni Atlantic pigtoe Clam Proposed threatened At Risk Species (ARS) Lasmigona subviridis Green floater Clam Under review 3.7 Industrial Facility Discharges The Town of Carrboro MS4 jurisdictional area includes the following industrial facilities which hold NPDES Industrial Stormwater Permits, as determined from the NCDEQ Maps & Permits Data web page. Table 5: NPDES Stormwater Permitted Industrial Facilities Permit Number Facility Name NCG080676 Town of Carrboro-Public Works NCG140126 Southern Equipment Company-Chapel Hill Plant #16 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 required that other non-stormwater flows be specifically controlled by the Town of Carrboro. FINAL NCS000450 SWMP Town of Carrboro 10/4/2021 Page 9 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.

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. FINAL NCS000450 SWMP Town of Carrboro 10/4/2021 Page 11 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. 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.

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 FINAL NCS000450 SWMP Town of Carrboro 10/4/2021 Page 17 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 . 4.3 Shared Responsibility The Town of Carrboro will share the responsibility to implement the following minimum control measures, which are at least as stringent as the corresponding NPDES MS4 Permit requirement. The Town of Carrboro remains responsible for compliance if the other entity fails to perform the permit obligation, and may be subject to enforcement action if neither the Town of Carrboro nor the other entity fully performs the permit obligation. Table 9 below summarizes who will be implementing the component, what the component program is called, the specific SWMP BMP or permit requirement that is being met by the shared responsibility, and whether or not a legal agreement to share responsibility is in place.
