TENNESSEE VALLEY AUTHORITY KNOXVILLE.TENNESSEE 37902 SEP 15 198S Mr. Charles Horn, Chief Water Division Alabama Department of Environmental Management 1751 Federal Drive Montgomery, Alabama 36130 Attention: Ms. Treena G. Piznar

Dear Mr. Horn:

BROWNS FERRY NUCLEAR PLANT (BFN) NPDES PERMIT NO. AL0022080 UNIDENTIFIED SODIUM NITRITE USE In accordance with Part II.B.2(b) of the NPDES permit, this is to notify you that we have identified the use of sodium nitrite as a corrosion inhibitor at, BFN. The use of sodium nitrite is not identified in BFH's HPDES permit application. A reagent grade form of the chemical is used in various plant air conditioning systems and the reactor building closed cooling water system'. Also, a Halco product containing sodium nitrite is used in the diesel generators.

During ongoing maintenance activities, there is the possibility that leaks in these systems will allow the discharge of sodium nitrite at low levels. The plant air conditioning systems (dischargerserial number (DSH) 107 and 110),

reactor building closed cooling water system (DSH 104), and diesel generator cooling systems (DSN 108 and 109) would be points of concern. If applicable system trending data indicates a possible leak, the appropriate discharge point(s) will be checked. If a leak is found, BFH will monitor the discharge point until the leak is eliminated. The concentration of nitrite in the diffuser is not expected to exceed 1 part. per million. The use of sodium nitrite will be addressed in the new NPDES permit application which BFN will submit for your review in January 1989.
