Pretreatment Review of Industrial User Pretreatment Permit Renewal
Program: Durham County
WWTP: Durham County Triangle WWTP - NPDES #: NC0026051
Durham County
Dear Ms. Moore:
The Municipal Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment Permit (IUP)
renewal submitted by the Durham County Triangle WWTP (NPDES #: NC0026051) for the following Significant
Industrial User (SIU). The IUP was received by the Division on 12/29/2021.
SIU #
SIU NAME
DC-078
AstraZeneca Pharmaceuticals LP
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 Keyes McGee at [phone] [email:
[e-mail]]. Thank you for your continued support of the Pretreatment Program.
