Dear Ms. Moore:
The Pretreatment, Emergency Response, and Collection Systems Unit (PERCS) of the Division of Water
Resources has reviewed the Industrial User Pretreatment Permit (IUP) renewals submitted by Durham
County for the following Significant Industrial Users (SIUs). The IUPs were received by the Division on
July 18, 2019, with inspection reports received on July 26, 2019.
IUP #
SIU Name
DC-040
Cree RTP
DC-076
Cree, Inc.
The review indicates that the IUPs are adequate and meet the minimum requirements of 15A NCAC 2H
.0905 and .0916 and 40 CFR 403.8(f)(1)(iii). 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.
Thank you for your continued support of the Pretreatment Program. If you have any questions or
comments, please contact me at [phone] [email: [e-mail]] or Deborah Gore,
Unit Supervisor at [phone] [email: Debora [e-mail]].
Sincerely,
