This SWMP identifies the specific elements and minimum measures that the Town of Benson 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 NCS000558, 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 Benson and located within the corporate limits of the Town of Benson. In preparing this SWMP, the Town of Benson 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.

The map was generated in 2015. Table 1: Summary of MS4 Mapping NCS000558 SWMP Town of Benson July 1, 2021 Page 6 Percent of MS4 Area Mapped 100 % No. of Major Outfalls* Mapped 29 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 Benson MS4 is located within the Neuse and Cape Fear River Basins 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 Table 2: Summary of MS4 Receiving Waters Receiving Water Name Stream Index / AU Number Water Quality Classification 303(d)'Listed Parameter(s) of Interest Drivin Branch (Neuse RB) 27-52-6-1 C; NSW No Data Mingo Swamp (Cape Fear RB) 18-68-12-2 C; Sw No Data Hannah Creek (Neuse RB) 27-52-6 C; NSW Benthos, Dissolved OYygen(4mg/L, AL, FW) East Mingo Swamp (Cape Fear RB) 18-68-12-2-1 C; Sw No Data 3.4 MS4 Interconnection NCS000558 SWMP Town of Benson July 1, 2021 Page 7 NCDOT owns several roadways within the Town's corporate limits. The map below identifies the roadways owned and maintained by NCDOT. The storm drain system associated with these roadways is interconnected with the Town's stormwater system. 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 5: NPDES Stormwater Permitted Industrial Facilities Permit Number Facility Name NCG210474 McIntosh Box and Pallet Co. -Benson NCG170407 Chicopee, Inc. NCG11062 Benson WWTP 3.8 Non-Stormwater Discharges The water quality impacts of non-stormwater discharges have been evaluated by the Town of Benson as summarized in Table 6 below. The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality. NCS000558 SWMP Town of Benson July 1, 2021 Page 9 Street washing discharges are addressed under the Pavement Management Program in Part 10 of this SWMP. The Division has not required that other non-stormwater flows be specifically controlled by the Town of Benson. 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 have not been evaluated by the Town of Benson to determine whether they may significantly impact water quality. If it is determined that car washing with detergents is not incidental, then the Town of Benson will prohibit this activity if it results in washwater reaching a storm drain. Table 6: Non-Stormwater Discharges Non-Stormwater Discharge Water Quality Impacts Water line and fire hydrant flushing Incidental Landscape irrigation Incidental Diverted stream flows Incidental Rising groundwater Incidental Uncontaminated groundwater infiltration Incidental Uncontaminated pumped groundwater Incidental Uncontaminated potable water sources Incidental Foundation drains Incidental Air conditioning condensate Incidental Irrigation waters Incidental Springs Incidental Water from crawl space pumps Incidental Footing drains Incidental Lawn watering Incidental Residential and charity car washing Incidental Flows from riparian habitats and wetlands Incidental Dechlorinated swimming pool discharges Incidental Street wash water Incidental Flows from firefighting activities Incidental 3.9 Target Pollutants and Sources Based upon observations by Town staff and complaints from citizens, litter and yard waste has been identified as a potential stormwater pollutant. Also, given that the Town limit is within the Neuse Riverbasin, nitrogen is also a potential pollutant. 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 Benson has evaluated schools, homeowners and businesses as target audiences that are likely to have significant stormwater impacts. NCS000558 SWMP Town of Benson July 1, 2021 Page 10 The Town of Benson addresses litter and yard waste pollutants by reaching out to individual property owners that are not in compliance with Town Ordinances. The Town conducts a community litter sweep in April each year. Also, the Public Works Department operates a street sweeper and collects yard waste weekly.

Under the oversite of the Director of Public Works and Utilities, staff members from different departments participate in assigned roles to meet the goals of the program. The Town of Benson also relies on Johnston County Public Utilities for some responsibilities associated with the program.

The budget includes the permit administering and compliance fee, which is billed by the Division annually. The Town of Benson implemented a Stormwater Fee in Fiscal Year 2020-2021. A charge of $2.50 per month is assessed on each utility bill. This fee generates $52,050 per year. 4.3 Shared Responsibility The Town of Benson 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 Benson 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 Benson 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.
