Mr. Wise,
Thank you for the outfall information. I've made the updates and additions to this permit in our database. You can run

DEMLR Stormwater Program
1612 MSC
Raleigh, NC 27699-1612
Ms. Georgoulias,
Charlotte Water (CLTWater) maintains coverage under the State's General Permit for industrial stormwater
discharges from Treatment Works at the Irwin Creek Wastewater Treatment Plant (4000 Westmont Drive,
Charlotte, NC 28217). The facility's certificate of coverage is NCG110008.
CLTWater recently updated all aspects of our Integrated Contingency Plan (ICP) for this facility, which includes
permit and SWPPP requirements of the General Permit. The Irwin Creek Wastewater Treatment Plant has
undergone significant construction within the past few years, in some situations impacting how stormwater flows
across the landscape. Part of the thorough ICP update included working with a consultant to properly designate
outfalls at their terminus with either the property boundary or a jurisdictional surface water. This assessment led
to the relocation of some outfalls.
Below is a table that provides the coordinates for all six stormwater discharge outfalls (SDOs) at this facility, as well
as a brief explanation of any proposed/recommended actions. We have also included several images from our site
maps that show the affected SDOs (005, 008, 009, & 012). Not all SDOs changed with the latest update, but we
wanted to provide DEMLR with the most complete and up to date information. You will notice that the numbering
of these outfalls is not sequential as some outfalls were previously determined by NCDEMLR (many years ago) not
to be regulated per the permit because they lacked discharges from industrial activities. For consistency with our
program, we have decided to maintain the numbering/naming convention from the past. CLTWater is happy to
host DEMLR staff to review these proposed changes and properly formalize them as part of our facility's permit. In
the event that DEMLR does not provide a timely written response (whether in conjunction with a site visit or not),
CLTWater will proceed with these SDO designations in the near future.
