Subject:

Envi ronmental Deviation The following deviation was reported to Mr. Walt Baunack, Office of Inspection and Enforcement, Region 1, United States Nuclear Regulatory Corrrnission on January 6,1976.

Reference:

LicenseNumberDPR-44/56 Envi ronmental Technical Speci fications: 2.2.2 Report No.: 50-277/278-76-2 Report Date: Janua ry 15, 1976 Deviation Date: January 5,1976 Faci li ty: Peach Bottom Atomic Power Station Units 2 & 3 R.D. #1, Delta, Pennsylvania 17314 Identification of Deviation 1 Sewage plant effluent suspended solids in excess of the Envi ronmental Technical Speci fication limit. ,

Description of Devia tion:

Routine gravimetric analysis showed that the suspended solids concentration of the sewage plant effluent was 62 ppm greater than that of the riverwater.

Designation of Apparent Cause of Deviation:

An investigation sl owed that solids had been carried 'over from the settling zone into the chlorine contact tank due to inadequate sludge return flow.

and from the chlorine contact tank to the effluent due to high 76o 7 642 /

_ Analysis of Deviation: ,

, Because of the short period of time that the sewage plant effluent was out of specification, no detrimental effects to the envi ronment are anticipated.

Corrective Action:

The chlorine contact tank was pumped out and the sludge return line cleaned. A follow-up sample taken on January 6,1976 revealed that the effluent suspended solids concentration was within Environmental

, Technical Specification limits. The Philadelphia Electric Company Engineering Department is investigating the Environmental Deviation.
