Subject: Pretreatment Review of Industrial User Pretreatment Permit
City of Durham
NPDES #:N00047597 (South Durham WWTP)
Dear Mr. Battle:
The Pretreatment, Emergency Response and Collection Systems (PERCS) Unit of the Division of Water
Resources has reviewed the Industrial User Pretreatment Permits (IUP) renewal submitted by the City of
Durham. The draft IUP was received by the Division on March 26, 2019, with signed copy received May 6,
2019.
IUP # SIU
2015 1 Angelica
The review indicates that with the following comments, the IUP is adequate and meet the minimum
requirements of 15A NCAC 2H .0905 and .0916 and 40 CFR 403.8(f)(1)(iii). The allocation table, maintained
in the Division's database, has been updated accordingly.
1. The pollutants checklist in the application were checked as absent at the facility, but did not
provide any indication as to whether pollutants are present or absent in the discharge. The PERCS
Unit is aware that in fact the POCs are absent in the discharge. Please insure all future permit
applications have two checks for each parameter.
2. The inspection form received was for Southeastern Freight Lines, please submit a copy of the most
recent on -site inspection form to the PERCS Unit before June 14, 2019.
3. Please submit a copy of the transmittal letter to the PERCS Unit before June 14, 2019.
Federal and State pretreatment regulations require the local delegated pretreatment program to
effectively control and document the discharge of wastewater from Significant/Categorical Industrial
Users to the POTW. It is the POTW's responsibility to ensure that these objectives are consistently met.
