Subject: NPI?ES General Permit NC500000 Coverage Renewal Amendment
Richmond County Combustion Turbine Plant — COC NCG500594
Dear Sir:
Progress Energy Carolinas, Inc., proposes to amend the National Pollution Discharge Elimination System
(NPDES) General Permit NCG500000 Notice of Renewal Intent application submitted in May 2007 for
the above referenced facility.
On the currentlplant site, the Richmond County Combustion Turbine Plant intends to add an additional
combined cyclunit, anticipated operational date of June 2011, with an accompanying new cooling
tower. The wastewater from the new unit will be directed to the existing permitted outfalls. Upon
completion, the estimated discharge to Outfall 001, which primarily receives wastewater from non -
contact cooling water (evaporative coolers), will increase to 25,000 GPD and the estimated discharge to
Outfall 002 (Marks Creek), which primarily receives wastewater from the cooling tower blowdown, will
increase to 540 000 GPD. Discharges to Outfall 003 will continue to be infrequent.
The currently -approved water treatment products will be used for the new unit but because there will be a
change in estimated discharge volumes, revised Biocide/Chemical Treatment Worksheet-Form 101
information was submitted to the Aquatic Toxicology Unit for approval (see Enclosure for summary).
Progress Energy Carolinas, Inc., appreciates the continued cooperation demonstrated by the Division of
Water Quality staff in responding to its permitting needs. Please contact Robin Bryson at [phone]
with any questions.
