Pretreatment Review of Industrial User Permit Drop Request
Program: Yadkin Valley Sewer Authority
WWTP: Yadkin Valley Sewer Authority WWTP, NPDES #: NC0020567
Surry County
Dear Ms. Johnston:
The Municipal Unit of the Division of Water Resources has reviewed the request to drop the following industry
from the list of significant industrial users (SIUs) for Yadkin Valley Sewer Authority, Yadkin Valley Sewer
Authority WWTP (NPDES #: NC0020567). The drop request was received by the Division on July 28, 2021.
SIU #
SIU NAME
IWP002
Weyerhaeuser NR Company
The review indicates that the SIU no longer discharges process wastewater and thus no longer meets the definition
of a SIU. Therefore, the SIU drop request is approved based on compliance with 15 NCAC 2H .0907(b). The
SIU list which is part of your approved pretreatment program is hereby modified.
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 Michael Montebello at (919) 707 -3624 [email:
[e-mail]]. Thank you for your continued support of the Pretreatment Program.
