Subject: Pretreatment Review of Industrial User Pretreatment Permit Modifications
Program: City of Mount Holly; City of Mount Holly WWTP
NPDES #: NC0021156, Gaston County
Dear Mr. Wilson:
The Municipal Unit of the Division of Water Resources has reviewed the 2 Industrial User Pretreatment Permit (LUP)
modifications submitted by the City of Mount Holly for the following Significant Industrial Users (SIUs). The IUP
modifications were received by the Division on 11/02/2023.
SIU # SIU NAME
1157 American & Efird LLC
1163 Daimler Trucks North America LLC
The review indicates that the IUPS are adequate to meet the minimum requirements of 15A NCAC 2H .0916 and 40
CFR 403.8(f)(1)(iii). The updated allocation table is saved in the City of Mount Holly file.
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 (SIU's). 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.
If you have any questions or comments, please contact Keyes McGee at [phone] [email:
keyes.mcgee(cr�,deq.nc.gov] or Octavio Henriquez at [phone] [email: octavio.henriquez(c-r�,deq.nc.gov]. Thank
you for your continued support of the Pretreatment Program.
