Subject: Pretreatment Review of Industrial User Pretreatment Permit Modification
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 following Industrial User Pretreatment
Permit (IUP) with the modification submitted by Durham County for their Significant Industrial User (SIU). The IUP
submission was received by the Division in 5/31/2022.
SIU #
SIU NAME
DC-095
PowerSecure, Inc.
The review indicates that the IUP is adequate and meeting 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.
