Subject: RE: 100% domestic permits with permitted flows of 1.0 MGD
You are just a wealth of information today!
FYI —Thanks for the permit list on Ron and Trupti — I'll get back to you on that, I have assigned a few of those.
And, I'm glad you are paying attention to some of these possibilities.

Subject: 100% domestic permits with permitted flows of 1.0 MGD
This information is FYI and for the permit files.
There are 4 permits for 100% domestic discharges that have expansion flows of 1 MGD. They are:
NCO033111
Carolina Water Service, Inc. of North Carolina
Fairfield Harbour WWTP
NCO061719
Aqua North Carolina, Inc.
Woodlake Country Club WWTP
NCO038831
Carolina Water Service, Inc. of North Carolina
Carolina Trace WWTP
NCO022900
Carolina Water Service, Inc. of North Carolina
Sugar Mountain WWTP
None of the facilities has expanded to 1 MGD. None are likely to in the near future. The highest flows from the past 12
months are:
NC0033111— 0.386 MGD
NC0061719 — 0.106 MGD
NCO038831— 0.292 MGD
NCO022900 — 0.15 MGD
Should either permittee ever announce expansion to 1.0 MGD, we will need to evaluate the relevant WWTP[s] with the
EPA Rating Sheet to determine if this would make the relevant permit a Major permit. No privately -owned 100%
domestic discharge has ever expanded to 1 MGD or beyond. I don't know if a new model would be required, or what
basin -specific criteria might come to bear.
