This SWMP identifies the specific elements and minimum measures that the Town of Spring Lake 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 NCS000438, 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 Spring Lake and located within the corporate limits of the Town of Spring Lake. In preparing this SWMP,the Town of Spring Lake 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.

Major ou falls 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 Spring Lake 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 Waterbodv 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 Water 303(d)Listed Parameter(s) Index/AU Quality of Interest Number Classification Tank cDuffie Creek 18-23-27 C None Jumping Run Creek 18-23-29 C None Muddy Creek 18-23-26 C None Lower Little River 12-23-24 C None *Water Quality Classification C: Aquatic Life, Secondary Recreation,Fresh Water 3.4 MS4 Interconnection The Town of Spring Lake MS4 is interconnected with another regulated MS4 and directly receives stormwater from Fort Bragg Young Lake which then discharges to the receiving waters as listed in Table 2 above. The MS4 does interconnect with the statewide NCDOT MS4 and includes: a. The interconnection is receiving stormwater from the NCDOT MS4. The number of interconnections is known/estimated/unknown. Quantity: N/A b. The interconnection is discharging stormwater into the NCDOT MS4. The number of interconnections is known/estimated/unknown. Quantity: N/A c. The Town of Spring Lake MS4 mapping does identify pre-construction interconnections with the NCDOT MS4 along NC-87 d. The Town of Spring Lake MS4 mapping does include NCDOT MS4 outfalls. NCS000438 SWMP Town of Spring Lake 21 February, 2023 Page 4 3.5 Total Maximum Daily Loads(TMDLs) The Town of Spring Lake does not have any impaired water bodies as indicated in the NCDEO Modeling &Assessment Unit web page. Therefor the MS4 has no TMDL reporting requirements. However, a periodic review of the web page will ensure that we stay in compliance should any of our waterbodies get put on this 1 Table 3: Summary of Approved TMDLs Water Body Name TMDL Pollutant(s) of Concern Stormwater Water Waste Quality Load Recovery Allocation Program NA 3.6 Endangered and Threatened Species and Critical Habitat Significant populations of threatened or endangered species and/or critical habitat are not 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 NA 3.7 Industrial Facility Discharges The Town of Spring Lake MS4 jurisdictional area includes the following industrial facilities which hold NPDES Industrial Stormwater Permits, as determined from the NCDEO Maps&Permit Data web page.

The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality. The Town of Spring Lake has evaluated residential and charity car washing and street washing for possible significant water quality impacts. 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 Spring Lake. Wash water associated with car washing that does not contain detergents or does not discharge directly into the MS4 is considered incidental. Charity carwashes and personal washing at residences are not frequent enough at this point to warrant specific addressing in ordinances. At this time we remind residents to wash on their lawns or use non-detergent based washes to prevent discharge through PSAs on the webpages and social media, as well as in person visits as needed Table 6: Non-Stormwater Discharges Non-Stormwater Dischar a 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 crawls ace pumps Incidental Footing drains Incidental Lawn watering Incidental Residential and charity car washing Possible Flows from riparian habitats and wetlands Incidental Dechlorinated swimming pool discharges Incidental Street wash water Incidental Flows from firefighting activities Incidental NCS000438 SWMP Town of Spring Lake 21 February, 2023 Page 6 3.9 Target Pollutants and Sources In addition to those target pollutants identified above,the Town of Spring Lake is aware of other significant water quality issues within the permitted MS4 area. Based on user reports,public areas such as Mendoza Park and the Main Street area often contain litter and animal waste.In addition,yard waste and litter in most neighborhoods tends to gather in the drainage basins,especially around bus stops 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 Spring Lake has evaluated schools, homeowners and businesses as target audiences that are likely to have significant stonnwater impacts.

The SPCA requirements include reducing pollutants in stormwater runoff from construction activities that result in land disturbance of greater than or equal to one acre, and includes any construction activity that is part of a larger common plan of development that would disturb one acre or more. The state SPCA Program is either delegated to a city/town, delegated to a county,or implemented by NCDEQ in non- delegated areas.

Pollution prevention and good housekeeping is accomplished through the implementation of seven required programs, which collectively address the ultimate goal of preventing or reducing pollutant runoff from municipal operations such as parks and open space maintenance, fleet and building maintenance,new construction and land disturbances, and municipal storm sewer system maintenance. Pollution prevention and good housekeeping for municipal operations includes the following programs: 1. Municipal Facilities Operation and Maintenance Program 2. Spill Response Program 3. MS4 Operation and Maintenance Program 4. Municipal SCM Operation and Maintenance Program 5. Pesticide, Herbicide and Fertilizer Management Program 6. Vehicle and Equipment Maintenance Program 7. Pavement Management Program The Town of Spring Lake will manage, implement, and report the pollution prevention and good housekeeping BMPs as specified in Table 21 below for each required program.
