Subject: Pretreatment Review of Industrial User Permit Modification
Program: Winston-Salem

Forsyth County
Dear Joel Freeman:
The Municipal Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment Permit
(IUP) modification, received by the Division on June 17, 2021, submitted by the City of Winston-Salem for the
following Significant Industrial User (SIU).
IUP #
SIU NAME
3054
Environmental Relief Technology
The review indicates that the IUP is adequate and meets the minimum requirements of 15A NCAC 2H .0905 -
.0916 and 40 CFR 403.8(f)(1)(iii). The IUP was modified to decrease effluent limitation for fats, oils, grease (FOG)
to 150 mg/1, and increase monitoring frequency for FOG and pH.
Regardless of this approval action today, within 180 days of the effective date of any reissued/modified NPDES
permit, 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 SIUs regardless of timeframe.
Federal and State pretreatment regulations require the local delegated pretreatment program to effectively control
and document the wastewater discharge from SIUs 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 Diana [diana.yitbarek@ncdenr.gov], the Pretreatment Coordinator Keyes [keyes.mcgee@ncdenr.gov], or
the Unit Supervisor, Michael at[michael.montebello@ncdenr.gov].
