Subject: Review of Industrial User Pretreatment Permit
Program: Yadkin Valley Sewer Authority (NPDES Permit No: NC0020567)
Surry County
Dear Ms. Johnston:
PERCS Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment Permit (IUP)
submitted by the Yadkin Valley Sewer Authority for the following Significant Industrial User (SIU). The IUP
was received by the Division on February 21, 2019.
IUP # SIU Name
IWP002 Weyerhaeuser NR Company
The review indicates, with the observation below, that the IUP is adequate and meets the minimum
requirements of 15A NCAC 02H .0905 and .0916 and 40 CFR 403.8(f)(1)(iii).
1. According to the information provided in the application, it appears that Weyerhaeuser facility's
operation started September 1986, which lists the industry as a New Source (New Source date
10/31/79). Weyerhaeuser would not be considered Categorical Industrial User, as there are no
Pretreatment Standards for New Source (PSNS), per 40 CFR 429.
2. It appears that submitted allocation table (AT) was not updated correctly, per current IUP limits.
Please save the updated AT (attached) for future references.
3. It is noticed that provided SIU inspection form was not signed and dated. In future, please make
sure all inspections forms are completed, signed and dated.
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 Monti Hassan at [phone] [email: Monti. [e-mail]].
