(SWMP) is to establish and define the means by which the City of Morganton will comply with its National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) Permit and the applicable provisions of the Clean Water Act, to meet the federal standard of reducing pollutants in stormwater runoff to the maximum extent practicable. This SWMP identifies the specific elements and minimum measures that the City of Morganton will develop, implement, enforce, evaluate, and report to the North Carolina Department of Environmental Quality(NCDEQ) Division of Energy, Minerals and Land Resources(DEMLR,or Division) in orderto comply with the MS4 Permit number NCS000498, 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 Morganton and located within the corporate limits of the City of Morganton. In preparing this SWMP, the City of Morganton 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 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 interconnection is receiving and discharging stormwater from the NCDOT MS4. The number of interconnections is unknown. b. The City of Morganton MS4 mapping does include NCDOT MS4 outfalls as the mapping program identified stormwater structures regardless of the owner. 3.5 Total Maximum Daily Loads (TMDLs) With the exception of the Statewide TMDL for mercury listed in Table 3 below, no TMDLs 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 W LA. While the Statewide TMDL for mercury does not require any actions by the NPDES Stormwater Permittee because most mercury in stormwater comes from atmospheric deposition, the City provides Public Education for fish consumption through BMP 5.

NCGNE1411 Jackson Corrugated NCS000009 SGL Carbon, LLC NCS000332 Hexion Morganton Facility 3.8 Non-Stormwater Discharges The water quality impacts of non-stormwater discharges have been evaluated by the City of Morganton as summarized in Table 6 below. Only emergency firefighting activities are considered an allowable non- stormwater discharge. The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality. Discharges from firefighting training activities and vehicle washing are not allowable non-stormwater discharges. Allowable and non-allowable stormwater discharges are addressed through Public Education and Outreach and Pollution Prevention and Good Housekeeping BMPs to educate residents and municipal staff. The City of Morganton has evaluated car and street washing for possible significant water quality impacts.Wash water associated with car washing that does not contain detergents or does not discharge directly into the MS4 is considered incidental. Other vehicle washing discharges that do contain detergents have been evaluated by the City of Morganton. The Division required remedy for an illicit connection from a wash station at the rehouse Garage facility identified during the audit. This municipal wash station is currently in compliance with the required regulations. The City is also aware of several car-washing businesses. These identified businesses and, their associated car-washing practices are addressed through BMPs to educate residents, business-owners, and municipal staff on the possible effects of detergents entering the surface waters as well as illicit discharge inspections. NCS000498 SWMP City of Morganton April 15, 2024 Page 12 The City uses a "wet' street sweeper and therefore street wash water has been evaluated. The street sweeper generates a mist that dampens solids to keep dust down and allow for collection but does not discharge enough water to create runoff. Wet solids from the street sweeper are stored at a City-owned facility with procedures for covered storage and handling;therefore, street wash water is considered an incidental water quality impact. 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 Incidental Flows from firefighting activities Incidental 3.9 Target Pollutants and Sources In addition to possible non-stormwater discharges identified above, the City of Morganton is aware of other significant water quality issues within the permitted MS4 area. These include impairments listed in Section 3.3, as well as those described in the following: • Hunting Creek Watershed Plan (2011) and NCDEQ Watershed Plan Fact Sheet • Western Piedmont Source Water Protection Plan (2014) and NCDWR Source Water Assessment Program Report for Morganton (2020) NCS000498 SWMP City of Morganton April 15, 2024 Page 13 Table 7 below summarizes the water quality pollutants identified throughout Part 3 of this SWMP and the likely activities/sources/targeted audiences attributed to each pollutant, as well as identifying the associated SWMP program(s) that address each. In addition, the City of Morganton has evaluated schools, homeowners, and businesses as target audiences that are likely to have significant stormwater impacts.
