Dear Hr. Patrick:
NOTIFICATION OF NONCOHPLIANCE WITII EFFLUENT LIHITATIONS - NPDES PERHIT NO. AL0022080 -
BROWNS FERRY NUCLEAR PLANT Descri tion of the dischar, e--Discharge No.
007 - Radwaste systems discharge.
A sample co ected on Hay 2, 1982 contained 124 mg/L of su'spended
- solids, exceeding the daily maximum permit limit of 100 mg/L.
Cause and eriod of the noncom liance--The prerelease analysis indicated that t te xsc targe rom t te aun ry rain tank would be less than the permitted daily maximum limit.
- However, the filtration system failed to perform to the degree estimated in the prerelease analysis.
The laundry drain tank was discharged
~ from 1:25 p.m. to 2:25 p.m.
and from 2:40 p.m. to 5:05 p.m.
on Hay 2, 1982.
The period of noncompliance was 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> and 25 minutes.
The laundry drain tank was discharged at a rate of 41 gpm into the condenser cooling water dis-
- charge, which had a flow rate of 600,000 gpm during the release.
Therefore, the possibility for adverse environmental impact on the Wheeler Reservoir during the release was significantly reduced.
Ste s taken to reduce eliminate and revent recurrence of the noncom l in disctar e--
te isctarge was terminate at:
p.m.
w en t>e ana ysis o t e samp e collected at 2:25 p.m.
was completed and indicated the noncompliance.
The contents of the tank were reprocessed to lower the suspended solids con-centration before initiating further releases.
The filter-cartridges in use at the time of the noncompliance were replaced with new cartridges as a pre-caution.
An investigation is being conducted to determine if there is a pos-sible inconsistency in the quality of filters used in this treatment
