HO-950531 William R. Robinson Vice President Harris Nuclear Plant Mr. Kenneth Schuster Raleigh Regional Supervisor North Carolina Division ofEnvironmental Management 3800 Barrett Drive, Suite 101 Raleigh, NC 27602 Shearon Harris Nuclear Power Plant National Pollutant Discharge Elimination System (NPDES) Permit No. NC0039586
Dear Mr. Schuster:
In accordance with Part II, E (9) (a) ofthe above-referenced NPDES Permit, on September 11, 1995 Ms. J. E. Garrett ofthe Raleigh Regional Office ofthe North Carolina Division ofEnvironmental Management was notified via telephone by Mr. R. C. Yates of CP&L's Environmental Services Section that a zinc excursion had occurred at Outfall 001 (cooling tower blowdown) ofthe Shearon Harris Nuclear Power Plant (Grade IIIfacility).
On September 8, 1995, plant personnel discovered zinc concentrations ofapproximately 3 parts per million(ppm) in the cooling tower blowdown discharge.
The zinc limitprescribed in the Harris Plant NPDES Permit is 1 ppm. The elevated zinc level in the discharge was the result of a decrease in the pH ofthe cooling tower water. Plant personnel subsequently adjusted the pH ofthe cooling tower water and returned the zinc concentration to within the permitted concentration on September 10, 1995. The cause ofthe pH change is being investigated.
No harm to the environment or human health occurred during or after the discharge.
This is based on detected zinc levels of.026 ppm at the outfall to Harris Lake.
Ifyou have any questions or comments regarding this information, please contact Mr. R. T. Wilson at (919) 362-2444. or Mr. R. C. Yates (919) 546-7777.
Sincerely, c:
