Dear Ms. Metcalf:
The Municipal Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment Permit
(IUP) modifications submitted by WSACC for the following Significant Industrial Users (SIUs). The IUPs were
received by the Division on 04/07/2021.
SIU #
SIU NAME
1028
Americhem Inc.
1029
Galvan Industries
1034
HeiQ Chem -Tex, Inc.
1030
Heritage -Crystal Clean, LLC
1041
Owens Corning
1026
Perdue Farms, Inc.

Star America

Stericycle, Inc.
The review indicates that the IUPs are adequate and meets the minimum requirements of 15A NCAC 2H .0905
and .0916 and 40 CFR 403.8(f)(1)(iii).
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.
