Stormwater Permit Certificate of Coverage No. NCG060220
Representative Outfall Status
Darling Ingredients Inc. - Union County
Dear Mr. Thelen:
The Mooresville Regional Office staff have reviewed your request dated August 3, 2021 for a determination
that stormwater discharge outfall (SDO) 003 be granted representative outfall status for stormwater outfalls
003, 004, 005, and 006. This approval is effective with the next sampling event. We also want to remind you
that the permit still requires Qualitative Monitoring be performed at all SDOs, regardless of representative
status.
Please remember that any actions you initiate in response to future benchmark exceedances as directed in the
tiered response provisions of your permit must address all drainage areas represented by SDO 004, SDO 005,
and SDO 006 where appropriate.
Please append this letter to your Stormwater Pollution Prevention Plan (SPPP) or permit to document that
representative outfall status. If changes in drainage areas, structures, processes, storage practices, or other
activities occur that significantly alter the basis of this approval, representative outfall status may no longer be
valid. You should either resume sampling at all SDOs, or reapply to this office for representative outfall
status based on updated information. If you have any questions or comments concerning this letter, please
contact James Moore at (704) 663-1699.
Sincerely,
ZD�occ�u3igned by,
