Dear Mr. Patrick:

NOTIFICATION OF NONCOMPLIANCE WITH EFFLUENT LIMITATIONS NPDES PERMIT y NO. AL0022080 BROWNS FERRY NUCLEAR PLANT Descri tion of the dischar I e Discharge Nos. 008, 009, and 010 Station sump unit Nos. 1, 2,! and'3. Samples collected on January 4, 1982 contained 230 mg/L, 320 mg/L, and 460 mg/L of.,suspended solids for unit Nos. 1, 2, and 3 station sumps, respectively. These samples exceeded the daily maximum limit'f 100 mg/L. These values were overlooked and not r'eported within the 5-day period.

I Cause and eriod of the noncom liance Water from Wheeler Reservoir is used in the raw cooling ~ater system at Browns Ferry Nuclear Plant. On January 3 and 4, 1982, a total of 3.4 inches of rainfall occurred causing a high increase in'urbidity and suspended solids. The raw cooling water system is equipped with strainers ahead of the pumps to prevent systerh'amage. Th'ese strainers are backwashed to the sump as necessary to maintain proper, operation of the system. In addition to high suspended solids from the reer, the backwashing of the strainers temporarily increases the suspended solids concentration in the sumps. These samples were apparently taken during or immediately following the backwash operations.

( I Ste s taken to reduce eliminate and revent recurrence of the noncom in

~dischhr e No,,vcorrective:,'action',has'been taken since the excursion 1

occurred'ecause, of,'the ".combination of, high suspended solids due to heavy rainfall and" strainer backwashing. Thus, these two occurrences are not typical of, normal sump operation.

Sincerely, g~Mohamed Assistant
