F E N O C Perry Nuclear Power Plant Fisho A~rOe;;==" W"_l 10 Center Road Perry, Ohio 44081 James R. Hayes 440.280-7519 Manager-Radwaste, Environmental, Chemistry Fax: 440-280-5681 March 24, 2003 PY-CEI/OEPA-0396L Ohio Environmental Protection Agency Division of Surface Water P. 0. Box 1049 Columbus, OH 43216-1049 Ladies and Gentlemen, As, discussed with Mr. Erm Gomes of the Ohio Environmental Protection Agency, the Perry Nuclear Power Plant (PNPP) will be performing an acid flush of the dechlorination piping to correct clogging problems in inaccessible piping. The product to be used is inhibited hydrochloric acid at concentrations of less than 10%. PNPP will use no more than 100 gallons of this solution ( 10% hydrochloric acid and city water) at flow rates no greater than Igallon per minute. A pH meter will be use to continuously monitor the effluent and will be recorded every half-hour during the flush. If the effluent limit is approached, the flush will be secured to prevent an effluent limit violation. The flush is tentatively scheduled to be performed between March 27 and March 31, 2003 If you have any questions or require additional information, please contact Mr. Leo Harte at (440) 280-5514.
Very Truly Yours, (E

Perry Nuclear Power Plant FENOC Memorandum RECS-03-00040T Date: 3/21/03; 08:15 AM Mr. Erm Gomes of the Ohio EPA returned Mr. Leo Harte's telephone call of 3/20/03. This call was made to discuss using an acid to flush the dechlorination lines, which have continued to clog since converting from sodium sulfite to sodium bisulfite. Mr. Harte's original call requested what information the OEPA would require and requested if a rapid response was possible due to the current inability to chlorinate without dechlorination. In Mr. Hartes absence, Mr. Jamie Balstad accepted Mr.
Erm Gomes return call at 08:15 Am on 3/21/03. Mr. Balstad reviewed with Mr. Gomes the information proVide-db Mr. Haff &.77r; Gomes was info6rmed that the flush was tentatively scheduled for March 27th and March 3 It, 2003. The chemical being used was inhibited hydrochloric acid at a concentration of less than or equal to 10%, and that PNPP would not use more than 100 gallons of the concentration at flow rates not greater than 1 gallon per minute. The duration of the flush would be 100 to 200 minutes based on the achievable flow rate. A pH meter would be used at the effluent sample point to monitor effluent and recorded every half hour during the flush. In addition, Mr. Gomes was informed that there was no expected change to the outfall pH based on the normal system flow of 40,000 gallons per minute. Mr. Gomes requested that this information be faxed for his review and that PNPP could expect his answer on 3/24/03.

Notes for Station Number 31B00016004:
I
- The Free Available Chlorine (FAC) and Total Residual Oxidants (TRO) limits are the maximum allowed at the outfall at any time.
Analyses are to be performed by amperometric titration, Orion Residual Chlorine Electrode, or other approved methods during chlorination and /or bromination. The daily grab samples for FAC and TRO shall represent the maximum concentration discharged during chlorination and/or bromination.
- Grab sample for TRO and FAC will be taken during treatment event.
- Free Available Chlorine or Total Residual Oxidants may not be discharged from any single generating unit for more than 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> per day.
(1) Total Residual Oxidants reflects the use of bromine compounds. Bromine can be used separately or in combination with chlorine. These limits are effective when bromine is used. Discharge limitations for TRO may be met using a dehalogenation agent, if necessary.
Dehalogenation shall be achieved by using stoichiometric calculations to determine the amount of dehalogenating agent necessary to completely eliminate the residual.
