Subject: Pretreatment Review of Industrial User Pretreatment Permit Renewal
Program: Durham County
WWTP: Durham County Triangle WWTP - NPDES #: NCO026051
Durham County
Dear Ms. Brixey:
The Municipal Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment Permit
(IUP) renewal submitted by Durham County for the following Significant Industrial User (SILT). The ]UP was
received by the Division on May 26, 2020.
SIU # SIU NAME
DC-053 United Therapeutics Corporation
The review indicates that the ]UP 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.
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.
Sincerely,
"DocuSigned bey:, I L
