Subject:
Pretreatment Review of Industrial User Pretreatment Permit Renewal
Program: City of Mount Holly
Wastewater Treatment Plant: City of Mount Holly WWTP
NPDES #: NC0021156
Gaston County
Dear Ms. Blackwell:
The Municipal Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment
Permits (IUP) renewals submitted by the City of Mount Holly (NC0021156) for the following Significant
Industrial Users (SIU). The submission was received by the Division on December 7th, 2022.
SIU #
SIU NAME

American & Efird LLC

Clariant Corporation

Daimler Trucks North America LLC
The review indicates that the IUPs are adequate and meet the minimum requirements of 15A NCAC 2H
.0916 and 40 CFR 403.8(f)(1)(iii). The allocation table, maintained in the Division's database, has been
updated accordingly.
Regardless of approval action today, within 180 days of the effective date of any reissued or 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 (S1Us). Pursuant
to 15A NCAC 2H .0907(b) either the Division or the permittee may initiate pretreatment program revisions.
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.
