The revision is to change the flow route of two existing discharges from a
permitted outfall to another permitted outfall. No modification of monitoring
requirements nor permit limits are being requested. Please let me know as soon
as possible when we may move forward with these changes.
You may proceed with the requested change in plant operations. The described
activities do not violate the requirements of NCG500000.

Richmond County Combustion Turbine Plant -- Certificate of Coverage NCG500594
NPDES General Permit NCG500000 Notice of Renewal Intent Application Amendment
Dear Mr. Weaver:
Progress Energy Carolinas, Inc. is hereby amending the current Richmond County Combustion Turbine
Plant Notice of Renewal Intent to redirect any discharge from existing cooling water basin drift/splash
from Outfall 001 to Outfall 003 and to redirect the discharge of the inline demineralization and gas
transfer membrane system from Outfall 002 to Outfall 001. These changes do not change the coverage
under the general permit for this site.
Grading for the new combined cycle unit, previously permitted, will alter the flow pattern near the
cooling water basin. The new gradient will direct any splash/drift that could come from the basin into
drainages that will ultimately flow to existing Outfall 003. There will be no change to the chemical make-
up or estimated flow of this discharge from this outfall.
The discharge from the inline demineralization and gas transfer membrane system is composed of
gaseous, demineralized water which is currently directed to the heat recovery steam generator (BRSG)
blowdown sump. The Richmond County Combustion Turbine Plant would like to redirect this discharge
to existing Outfall 001. There will be no new chemical additions to this waste stream as part of this
change but the estimated flow for this outfall would increase from 25,000 GPD to 35,000 GPD.
We thank you in advance for your attention to our permitting needs. If there are any questions about this
information please contact Ms. Robin Bryson by telephone at [phone].
