Pretreatment Review of Industrial User Pretreatment Permit Drop Request
Program: City of Mount Airy
WWTP: City of Mount Airy WWTP, NPDES # NC0021121, Surry County
Dear Mr. Marion:
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 the City of Mount Airy WWTP (NPDES #: NC0021121). The SIU
drop request was received by the Division on 05/09/2022:
SIU #
SIU NAME
0001
Professional Rental Service
The review indicates that the facility 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 15A 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 Keyes McGee at [phone] [email:
[e-mail]]. Thank you for your continued support of the Pretreatment Program.
