This SWMP identifies the specific elements and minimum measures that UNC-CH 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 NCS000441, as issued by NCDEQ. This permit covers activities associated with the discharge of stormwater from the MS4 as owned and operated by UNC-CH and located within the property owned by UNC-CH. In preparing this SWMP,UNC-CH 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.

These two points are where a UNC-CH storm system conveyance(pipe or ditch)of a major DRAFT NCS000441 SWMP UNC-CH March 25,2021 Page 4 outfall size(pipe greater than or equal to 36 inch or discharge area(DA)great than or equal to 50 acres) directly connects to the stormwater system of ToCH. This does not include places where streams cross from UNC-CH property to another jurisdiction. It does not include sheet flow where the acreage is less than 50 acres. It does not include conveyances(pipes or ditches)that are less than 36 inches in diameter or that convey DA of less than 50 acres. The same criteria were used to examine discharge from other jurisdictions to UNC-CH jurisdiction. There are none of those transitions. The UNC-CH stormwater GIS database was used to make these determinations \\facdraw\gis\Stormwater\GIS\Projects\NPDESdocumentation. This link can only be accessed by UNC- CH personnel. The MS4 does not interconnect with the statewide NCDOT MS4 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.

The budget includes the permit administering and compliance fee,which is billed by the Division annually. UNC-CH's stormwater program is funded by four different funding sources, as listed below. 1. Stormwater Utility Fees based on impervious area of UNC-CH property. 2. Water/Sewer Mark-Up on water, irrigation and sewer bills 3. Grant Overhead 4. Occasional On-Time Project Funding This funding is adequate for implementation of this SWMP and for compliance with the MS4 permit. The above funding sources are adequate for funding personnel,equipment, supplies,training and some stormwater related repairs and retrofits. The average budget for the past three years(2018—2020)has been approximately$678,000 per year. DRAFT NCS000441 SWMP UNC-CH March 25,2021 Page 9 There is a significant funding need for major repairs to stormwater infrastructure such as pipes and stormwater control measures. Capacity issues also need to be addressed. The deferred maintenance costs for stormwater at UNC-CH include both known issues($28,000,000)and likely issues($40,000,000). Addressing these repairs would require funding through the state appropriations process. 4.3 Shared Responsibility UNC-CH is not sharing responsibility(either contractually or through inter-local agreement)for any minimum control measures.
