Pretreatment Review of Industrial User Permit Drop Request
Program: Charlotte Water
WWTP: Sugar Creek WWTP, NPDES #: NC0024937
Mecklenburg County
Dear Mr. Gintert:
The Municipal Unit of the Division of Water Resources has reviewed the request to drop the following industry
from the list of significant industrial users (SIUs) for Charlotte Water, Sugar Creek WWTP (NPDES #:
NC0024937). The drop request was received by the Division on March 12, 2021.
SIU #
SIU NAME
5015
Wind River Environmental Services dba L & L Environmental Services
The review indicates that the SIU no longer discharges process wastewater and thus no longer meets the definition
of a SIU. Therefore, the SIU drop request is approved based on compliance with 15 NCAC 2H .0907(b) and
.0903(b)(33). The SIU list which is part of your approved pretreatment program is hereby modified.
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.
If you have any questions or comments, please contact Michael Montebello at (919) 707 -3624 [email:
[e-mail]] Thank you for your continued support of the Pretreatment Program.
