Dear Mr. Lynch:
0n September 29, 2021, Cheng Zhang of the Raleigh Regional Office (RRO) conducted an
audit of City of Durham's pretreatment program. The assistance given by Mr. Chris
McCorquodale, the Director of Public Works & Utilities, and Brittany York, the Wastewater
Superintendent, was greatly appreciated. The audit report is attached. Findings during the
inspection were as follows:
1. The city has two Significant Industrial Users (SIUs), neither is Categorical Industrial
Users (ClUs). The Division does not deem Mountaire Farms a CIU, even though
it is classified as 40 CFR 432 (documented on its Industrial User Pretreatment
Permits (IUP)), because of the lack of categorical discharge standards. It was
noted that neither SIU was in SNC for the most recent two semi-annual periods.
2. A review of the files containing the pretreatment program elements was conducted.
All elements are up to date. Update of Headworks Analysis is in review by the
Division.
