Dear Mr. Battle:
Pretreatment Review of Industrial User Pretreatment Permit Renewal
Program: City of Durham
WWTP: North Durham Water Reclamation Facility - NPDES #: NC0023841
Durham County
The Municipal Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment Permit
(IUP) renewal submitted by the City of Durham for the following Significant Industrial User (SIU). The IUP was
received by the Division on February 17, 2021.
SIU #
SIU NAME
1036
Cormetech
The review indicates that the IUP is adequate and meets 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.
Regardless of this approval action today, within 180 days of the effective date of any reissued NPDES permit (or
any subsequent NPDES permit modification) the Permittee would be required to submit to the Division a written
technical evaluation of the need to revise local limits (i.e., an updated IWS, or documentation of why one is not
needed). This action may include revising, updating or adding to the list of Significant Industrial Users (SIU's).
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.
If you have any questions or comments, please contact Michael Montebello at (919) 707 -3624 [email:
[e-mail]]. Thank you for your continued support of the Pretreatment Program.
