Subject: Pretreatment Review of Industrial User Pretreatment Permit Modification
Program: City of Lexington
WWTP: City of Lexington WWTP, NPDES #: NCO055786
Davidson County
Dear Ms. Minerali:
The Municipal Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment Permit
(IUP) modification submitted by the City of Lexington for the following Significant Industrial User (SILT). The
IUP was received by the Division on October 13, 2020.
SIU # SIU NAME
0038 Asco Power Technologies EE
The review indicates that with the following observation, the IUP is adequate and meets the minimum
requirements of 15A NCAC 2H .0905 and .0916 and 40 CFR 403.8(f)(1)(iii). The allocation table, maintained in
the Division's database, has been updated accordingly.
Please correct the following items and submit the new pages:
• Throughout the permit, update the effective date to October 13, 2020 to reflect the modifications.
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.
