This SWMP identifies the specific elements and minimum measures that the City of Newton 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 NCS000397, 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 Newton and located within the corporate limits of the City of Newton. In preparing this SWMP, the City of Newton 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. NCS000397 SWMP City of Newton January 27, 2020 Page 3 PART 3: MS4 INFORMATION 3.1 Permitted MS4 Area This SWMP applies throughout the corporate limits of the City of Newton, including all regulated activities associated with the discharge of stormwater from the MS4. The map below shows the corporate limits of City of Newton as of the date of this document. NCS000397 SWMP City of Newton January 27, 2020 Page 4 3.2 Existing MS4 Mapping The current MS4 mapping includes stormwater inflows, stormwater manholes, stormwater junction boxes, culvert drain pipes, stormwater discharges, and settling basins. The MS4 area has been mapped. However, previously unmapped stormwater infrastructure is still occasionally discovered. Stormwater inflows include information on material, diameter/box size, depth, and ground cover. Culvert drain pipes include information on diameter, box size, material, ground cover, and length. Stormwater discharges include information on material, diameter/box size, ground cover, and receiving stream. The stormwater discharges mapped include outfalls, but specific classification of major outfalls versus all other points of discharge has not occurred. Settling basins includes stormwater control measures (SCMs) and reports information including material, bank material, baffles, and weir information. Table 1: Summary of MS4 Mapping Percent of MS4 Area Mapped 95 % No. of Major Outfalls* Mapped unknown** 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. **Outfalls have been mapped but the classification of specific outfalls as major outfalls has not occurred, therefore the number of major outfalls is unknown at this time (See BMP No. 16). NCS000397 SWMP City of Newton January 27, 2020 Page 5 3.3 Receiving Waters The City of Newton MS4 is located within the Catawba 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 Table 2: Summary of MS4 Receiving Waters Receiving Water Name Stream Index / AU Number Water Quality Classification 303(d) Listed Parameter(s) of Interest Betts Branch 11-129-5-6 C Bills Branch (Bili Branch) 11-129-5-5 C Clark Creek (Shooks Lake) 11-129-5-(0.3)b C Benthos (Nar, AL, FW) Cline Creek 11-129-5-2 C Henry Fork 11-129-1-(12.5) C Hildebran Creek (Anthony Creek) 11-129-5-3 C Jacob Fork 11-129-2-(9.5) WS-III McLin Creek 11-76-5-(0.3) 11-76-5-(0.7) C WS-IV Benthos (Nar, AL, FW) Smyre Creek 11-129-5-4-1 C South Fork Catawba River 11-129-(0.5) WS-V Town Creek 11-129-5-4 C C – Class C (fishable/swimmable waters) WS III/IV/V – Water Source Benthos (Nar, AL, FW) – Narrative standard, aquatic life, fresh waters Data from 2018 NC Category 5 Assessments “303(d) List” Final and NC Surface Water Classifications Map. From the 2018 303(d) Listing and Delisting Methodology for Benthos: “Narrative criterion: Waters shall be suitable for aquatic life propagation and maintenance of biological integrity. NC uses benthic and fish community data to assess biological integrity. Biological integrity means the ability of an aquatic ecosystem to support and maintain a balanced and indigenous community of organisms having species composition, diversity, population densities and functional organization similar to that of reference conditions” 3.4 MS4 Interconnection The City of Newton MS4 is not interconnected with another regulated MS4 and directly discharges to the receiving waters as listed in Table 2 above. NCS000397 SWMP City of Newton January 27, 2020 Page 6 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) Stormwater Waste Load Allocation (Y/N) Water Quality Recovery Program (Y/N) Statewide Mercury N N The Statewide TMDL for Mercury does not require any actions by the NPDES stormwater permittees because most mercury in stormwater comes from atmospheric deposition. 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, as determined by 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. 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: Summary of Federally Listed Species/Habitat Impacted by Surface Water Quality Scientific Name Common name Species Group Federal Listing Status Haliaeetus leucocephalus Bald eagle Vertebrate BGPA Hexastylis naniflora Dwarf-flowered heartleaf Invertebrate vascular plant T BGPA – Bald and Golden Eagle Protection Act T- Threatened NCS000397 SWMP City of Newton January 27, 2020 Page 7 3.7 Industrial Facility Discharges The City of Newton MS4 jurisdictional area includes the following industrial facilities which hold NPDES Industrial Stormwater Permits, as determined from the NCDEQ Active NPDES Stormwater Permit List and/or Active Stormwater Permits Map.

The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality. The City of Newton has evaluated residential and charity car washing for possible significant water quality impacts. Street cleaning is performed with a dry street sweeping process so street washing discharges are not relevant to the MS4. The Division has not required that other non-stormwater flows be specifically controlled by the City of Newton. NCS000397 SWMP City of Newton January 27, 2020 Page 8 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 been evaluated by the City of Newton to determine whether they may significantly impact water quality. They were determined to be a possible cause of water quality impacts and will be addressed through public education efforts (See BMPs No. 5 and 7). 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 N/A Flows from firefighting activities Incidental 3.9 Target Pollutants and Sources In addition to those target pollutants identified above, the City of Newton is not aware of other significant water quality issues within the permitted 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 programs that address the target pollutants. In addition, the City of Newton has evaluated schools, homeowners and businesses as target audiences that are likely to have significant stormwater impacts. The schools were selected as a target audience due to the opportunity to affect positive change through education and involvement opportunities. Homeowners and businesses were identified as target audiences because they are likely sources of non-point pollution through uninformed management practices.

The budget includes the permit administering and compliance fee, which is billed by the Division annually. The stormwater program currently receives funding of approximately $750,000 per year; this is funded primarily through general funds. However, the Assistant Public Works Director and Utilities Director positions are funded through the Public Works Enterprise fund. In total the program receives 2 full-time equivalent staff for pavement management (1 full time street sweeper position and a leaf collection crew seasonally (13 weeks)) and less than 0.5 dedicated full-time equivalent staff for other program components. The program is currently under-funded to conduct all the proactive elements of the permit. Further fiscal analysis and investigation of funding options (such as additional general fund allocation or a stormwater fee) will be conducted as indicated in BMP No. 3 in order to fully fund the program by Permit year three. 4.3 Shared Responsibility The City of Newton 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 City of Newton remains responsible for compliance if the other entity fails to perform the permit obligation and may be subject to enforcement action if neither the City of Newton 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.
