discuss overall compliance please respond in writing within ten (10) business days after receipt of this Notice. A
review of your response will be considered along with any information provided on the submitted Monitoring

On September 12, 2018, I contacted Jason Robinson, left him a voice message, and followed up
with an email that the Triangle Wastewater Treatment Plant, NC0026051, had a BOD permit limit
violation for the first week of September. 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.

RE: Notice of Violation, NOV-2019-LV-0016

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.

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.
