Subject: Pretreatment Review of Long Term Monitoring Plan
Program: City of Lincolnton
WWTP: City of Lincolnton WWTP, NPDES #: NC0025496
Lincoln County
Dear Mr. Perry:
The Municipal Unit of the Division of Water Resources has reviewed the updated Long Term Monitoring
Plan (LTMP) for the City of Lincolnton. The submission was received by the Division on 8/24/2021.
The review indicates that with the following correction, the LTMP is adequate and meets the
requirements needed to establish a site -specific Headworks Analysis (HWA). Proper implementation of a
LTMP is also required by your NPDES permit. Please refer to the Comprehensive Guidance for North
Carolina Pretreatment Programs (Comprehensive Guide) for additional information and examples.
Modifications to this LTMP must be approved by the Division.
• In the revised LTMP submission, received by the Division on 9/16/2021, the Ag practical
quantitation limit (PQL) was changed from 5 ug/1 to 1 ug/1.
Please always use the lowest available PQL for each analyte.
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.
