This SWMP identifies the specific elements and minimum measures that The City of Gastonia 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 NCS000429,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 Gastonia and located within the corporate limits of The City of Gastonia. In preparing this SWMP,The City of Gastonia 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.

DRAFT NCS000429 SWMP City of Gastonia 03/28/2024 Page 4 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 unknown. b. The interconnection is discharging stormwater into the NCDOT MS4. The number of interconnections unknown. c. To date,The City of Gastonia MS4 mapping does not specifically identify interconnections with the NCDOT MS4. d. To date,The City of Gastonia MS4 mapping does not specifically include NCDOT MS4 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 Water Waste Quality Load Recovery Allocation Program Catawba Creek Nutrients N N Crowders Creek Nutrients N N Crowders Creek Fecal Coliform N N While no WLA exists for the City of Gastonia,TMDL pollutants are the subject of education and outreach to the public as a means of highlighting the deleterious impacts that they have on water quality. In addition,the City of Gastonia participates in an off right-of-way program that financially assists citizens who are contributing to sedimentation in waterways which is the primary transport method of the TMDLs identified in Table 3. This helps enhance not only education,but also provides a practical solution for mitigating TMDLs in our community. DRAFT NCS000429 SWMP City of Gastonia 03/28/2024 Page 5 3.6 Endangered and Threatened Species and Critical Habitat There are no significant populations of threatened or endangered species and/or critical habitat identified within the regulated MS4 urbanized area. This conclusion is 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. However, the species listed is not likely to be significantly impacted due to the quality of surface waters within their habitat.

The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality. The City of Gastonia 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 City of Gastonia. 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 DRAFT NCS000429 SWMP City of Gastonia 03/28/2024 Page 8 contain detergents have been evaluated by The City of Gastonia to determine whether they may significantly impact water quality 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 Possible *Appropriate Methods of discharging provided by staff Street wash water Incidental Flows from firefighting activities Incidental 3.9 Target Pollutants and Sources hi addition to those target pollutants identified above,The City of Gastonia is aware of other significant water quality issues within the permitted MS4 area. These include sediment, illicit discharges (eg..sanitary overflows),litter, and yard waste. Littering is not isolated to one area or neighborhood,The City of Gastonia has become aware of the fact that it is often more prevalent in locations where there is heavy foot traffic and public gathering spaces. Areas such as municipal greenways and parks are particularly susceptible to this form of pollution. Another,more deleterious form of pollution is sedimentation. The lion share of this method of pollution is from rapid development of the land. The City of Gastonia's primary soil type is a Cecil Urban Complex and Helena Urban Complex. Both soil types have been classified as Highly Erodible Land(HEL) as determined by the USDA-NRCS. Consequently,the land is prone to contribute to sedimentation and is a target pollutant that has gained great attention in this area. DRAFT NCS000429 SWMP City of Gastonia 03/28/2024 Page 9 Yard Waste is also a pollution source which is heightened during both spring and fall as the change of season brings yard debris/waste to street inlets.As a result,higher concentrations of ambient elements, such as Nitrogen and Phosphorous can discharge into the MS4. Sanitary sewer overflows can also be problematic during heavy rain events and improper disposal of chemicals from citizens can occur on occasion. Incidents of both pollution and sedimentation have been reported by the public and overtime The City of Gastonia has taken several steps toward reducing the number of incidents within the MS4 area. 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 Gastonia has evaluated schools, homeowners and businesses as target audiences that are likely to have significant stormwater impacts.

PART 8: CONSTRUCTION SITE RUNOFF CONTROL PROGRAM In accordance with 15A NCAC 02H .0153,The City of Gastonia relies upon the North Carolina Sedimentation Pollution Control Act(SPCA)of 1973 as a qualifying alternative program to meet a portion of the NPDES MS4 Permit requirements for construction site runoff control measures. 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.
