Dear Mr. Warr:

Re: Farley Nuclear Plant NPDES Permit No. AL0024619 9

In accordance with Part II.A.2 of the referenced permit, we are submitting a noncompliance that occurred as indicated by an analysis performed on June 2,1980, for the waste settling pond effluent (Discharge Point 005) . Analysis of the effluent gave a pH of 10.88. *

. c ..

i( .

During April,1980, lime was placed in the waste settling pond to neutralize sulfuric acid which had been transferred to the pond from a damaged storage tank. The acid was neutralized and no problem was encountered through the end of May. However, starting on May 6,1980, clarified water was discharged to the pond as part of the clarifier preoperational testing. Apparently the turbulence caused by the addition of clarified water assisted in gradually dissols f.ng the layer of calcium sulfate which had formed over the lime when the acid was neutralized by the lime. Once the layer was dissolved, the unreacted lime was expoced causing the pH to exceed the upper limit.

To prevent the recurrence of this violation, the discharge of the clarified water to the#ssil pond has been terminated. Acid will be added )

to the pond to reduce the pH and to neutralize the lime, l

If you have any questions, please contact me. 1 Yours truly, 1 M4C. hB17dinger, _Y Jr. M--e nag Y Ma.s '
