Pretreatment Review of Industrial User Permit Modification

Dear Joel Freeman:
The Municipal Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment Permit
(IUP) modification submitted by the Winston-Salem Winston-Salem for the following Significant Industrial User
(SIU). The IUP modification was received by the Division on January 12, 2021.
IUP #
SIU NAME
3010
Ardagh Metal Beverage USA, Inc
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 increase the daily maximum to 275,000 gpd and the
average flow limit to 237,500 gpd. For each WWTP, this industry's flow increment is as follows from 160,000 to
220,000 gpd for Archie Elledge and from 40,000 to 55,000 gpd for Muddy Creek. The WWTP controls the flow
distribution.
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 Significant Industrial Users (SIU's) 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 Yitbarek at 919 707-9130 [[e-mail]] or the Unit Supervisor, Michael
Montebello, at 919 707-3624[[e-mail]].
