Subject: Pretreatment Review of Industrial User Pretreatment Permit Modifications
Program: City of Thomasville
WWTP: Hamby Creek WWTP
NPDES#: NCO024112
Davidson County
Dear Ms. Conder:
The Municipal Unit of the Division of Water Resources has reviewed the draft Industrial User Pretreatment
Permit (IUP) modifications submitted by the City of Thomasville for the following Significant Industrial
Users (SIUs). The submission was received by the Division on January 11", 2022, and updated on March
21 st,2023.
IUP# SIU NAME
0008 Brass Craft-Thomasville
0028 Advance Material Coatings
0032 Hazmat Emergency Response&Remediation,Inc.
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) once signed by the City's Controlling Authority. The allocation table,
maintained in the Division's database,has been updated accordingly.
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 SIUs. 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.
