Subject: Pretreatment Review of Long Term Monitoring Plan(NPDES Permit Technical Evaluation)
Program: Charlotte Water
Wastewater Treatment Plant: Sugar Creek WRRF
NPDES#: NC0024937,Mecklenburg County
Dear Mr. Gintert:
The Municipal Unit of the Division of Water Resources has reviewed the updated Long Term Monitoring Plan
(LTMP)for the Charlotte Water's Sugar Creek WRRF(NC0024937).This submission was received 08/28/2024 in
response to the recently modified NPDES permit.
The review indicates that the LTMP is adequate to meet minimum requirements of 15A NCAC 2H .0906 (b)(3)
and for the continued local limits development as required by 40 CFR 403.8 (f)(4).
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 (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.
Thank you for your continued cooperation with the Pretreatment Program. If you have any questions or comments,
please contact Keyes McGee at(919) 707-3626 [email: keyes.mcgee&deq.nc.gov].
Sincerely,
