TENNESSEE VALLEY AUTHORITY KNOXVILLE. TENNESSEE 37902 126 Locust Street Building January 22, 1982 o Mr. James R. Patrick, Jr. , Chief Water Permit Branch, Water Management Division U.S. Environmenal Protection Agency, Region IV 345 Courtland S._eet, NE.

Dear Mr. Patrick:

NOTIFICATION OF NONCOMPLIANCE WITil EFFLUENT LIMITATIONS - NPDES PERMIT NO. AL0022080 - BROWNS FERRY NUCLEAR PLANT Description of the discharge--Discharge 007 - Radwaste system discharge.

A sample collected on January 18, 1982 contained 126 mg/L of suspended solids, exceeding the daily maximum limit of 100 mg/L.

Cause and period of the noncompliance--The prerelease analysis indicated that the discharge from the laundry drain tank would be less than the permitted daily maximum limit. The filtration system, however, failed to perform to the degree estimated in the prerelease analysis. The laundry drain tank was discharged from 8:40 a.m. to 9:40 a.m. and from 9:45 -a.m. to 11:20 a.m. on Janua ry 18, 1982. The period of noncompliance was 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> and 35 minutes. The laundry drain tank was discharged at a rate of 66 gpa into the condenser cooling water discharge, which had a flow rate of 800,000 gpm during the release. The possibility, therefore, for adverse environmental impact on.the Wheeler Reservoir during the release was significantly reduced.

Steps _taken to reduce, eliminate, and prevent recurrence of the noncomplying discharge--The discharge was terminated at 11:20 a.m. when the analysis of the sample collected at 9:40 a.m. was completed. The contents of the tank 'have been reprocessed to lower the suspended solids concentration before initiating further releases. The filter cartridges in use at the time of the noncompliance have been replaced as a precaution with new-i cartridges. The treatment -system is being evaluated to prevent any future noncompliances of this type.

Sincerely,

~ -
