This SWMP identifies the specific elements and minimum measures that the City of Belmont 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 NCS000409, as issued by NCDEQ. This permit covers activities associated with the discharge of stormwater from the MS4 as owned and operated by the City of Belmont and located within the corporate limits of the City of Belmont. In preparing this SWMP,the City of Belmont 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.

The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality.The City of Belmont 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 required that other non-stormwater flows be specifically controlled by the City of Belmont.The list of activities below are allowed provided they do not significantly impact water quality per our ordinance can be observed in table 6. 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 Possible Flows from riparian habitats and wetlands Incidental Dechlorinated swimming pool discharges Incidental Street wash water Possible Flows from firefighting activities Incidental 3.9 Target Pollutants and Sources In addition to those target pollutants identified above, the City of Belmont is not aware of other significant water quality issues within the permitted MS4 area. NCS000409 SW-MP City of Belmont 4/21/2023 Page 8 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 City of Belmont has evaluated schools, homeowners and businesses as target audiences that are likely to have significant stormwater impacts. Homeowners were selected as a primary target for the educational program due to the significant positive and negative impacts they could have on water quality.This is also the group that will most likely engage in activities such as disposal of auto oil and household wastes, disposal of yard wastes, application of fertilizers, pesticides and herbicides, pet waste, etc.Commercial facilities such as gas stations, car washes, restaurants, shopping centers and industrial warehouses/plants were targeted for the educational program due to the significant impacts they could have on water quality by potentially improperly handling and disposing of wastes, making illicit connections to the storm drain system, and practicing poor housekeeping at their facilities.Through education,the City is hopeful that it can inform and advise the public of the small behavioral changes that can be made to improve water quality.
