On September 3, 2018 we had a BOD result of 18.1 mg/1. The sample was split and analyzed by both Meritech, Inc. and Durham County's certified laboratory and both reported BOD results higher that we have ever seen at this facility. The second sample that week for BOD was 5.3 mg/1 calculating out to a weekly average of 11.7 mg/1. Our weekly permit limit is 7.5 mg/1; therefore, we exceeded our permit limit. All data was reviewed which included certified parameters, process control data, and data logged on the SCADA system. All other data was normal for our facility during this time. I spoke with the Compliance Manager concerning how the sample was handled and activities in the lab that may have been out of the norm to determine if possible sample contamination may have occurred. No cause could be detennined. 1 spoke with the Utilities Supervisor/ORC and reviewed the operations logbook to verify there were no changes in operation and no notes documenting any concerns during this time. On October 10, 2018,1 contacted Cheng Zhang and followed up with an email that we had violated our permitted monthly average for BOD. Our monthly average permit limit is 5.0 mg/1 and our monthly average for September was 5.1 mg/1. To date no cause for this result has been determined and we have not experienced any additional BOD exceedances. Salify Based on the following facts: this was an uncommon result, that we are an exceptionally performing facility, this is the only BOD violation in almost ten years, and that all reporting was conducted in a timely manner as required, I request that the Division of Water Resources not pursue further enforcement action. DURHAM COUNTY ’sl°"‘'oaK RE: Notice of Violation, NOV-2019-LV-0016 This is in response to the Notice of Violation dated January 11, 2019 and received by Durham County on January 15, 2019. The Triangle Wastewater Treatment Plant is an exceptionally performing facility and was granted reduced monitoring in February 2013. Durham County began operations of this facility in February 2009 and this is the second violation in almost ten years, this being the first violation for BOD. <^1881 •I Cc:Wendell Davis, County Manager (via email) Lowell Siler, County Attorney (via email) Jay Gibson, General Manager (via email) Shawn Davis, Utilities Supervisor/ORC (via email) Sincerely, Stephanie Brixey Deputy Director of E&ES/POTW Director For future correspondence from the Division of Water Resources to Durham County concerning permits NC0026051, WQCS00038, WQ0032821, and NCG110054 please copy me so I can respond to any request in a timely manner.

July 30, 2019 Subject: Dear Mr. Joyner: The Environmental Management Commission has previously approved the City of Durham's request for full delegation authority to issue sanitary sewer extension permits. In conjunction with that delegation, this office feels it appropriate to grant the City the approval to issue such permits based upon a block flow approval process. Previously, the Raleigh Regional Office has granted block flow approvals for the North Durham WRF totaling 8,500,000 GPD, and block flow approvals totaling 8,300,000 GPD for the Durham South WRF. The Raleigh Regional Office (RRO) requires that the Town submit a report summarizing the permitting activity by providing the following information for the permits that have been issued: Each of these facilities has a permitted capacity of 20.0 MGD. Based upon your most recent block flow quarterly reports for the period that ended in June 30, 2019, the North Durham WRF had a 12-Month average of 11.2 MGD, or approximately 56% of permitted capacity, while the South Durham WRF had a 12-month average flow of 10.86 MGD, or 54% of permitted capacity. North Carolina Department of Environmental Quality Division of Water Resources Raleigh Regional Office 1628 Mail Service Center, Raleigh, NC 27699-1628 Physical Address: 3800 Barrett Drive, Raleigh. NC 27609 919-791 4200 As requested in your letter dated July 19, 2019, the Raleigh Regional Office hereby grants an additional block flow allocation of 500,000 GPD for the North Durham Water Reclamation Facility, and an additional block flow allocation of 500,000 GPD for the South Durham Water Reclamation Facility. This additional allocation yields a total of 9,000,000 GPD granted for the North Durham WRF and 8,800,000 GPD for the South Durham WRF. As permits are issued by the City, the wastewater flow associated with those projects will be subtracted from the block flow allocation. When the issued permits have almost depleted the flow allocation, the City will request that it be granted an additional allocation. ROY COOPER Governor MICHAEL S.
