SUBJECT:

NPDES Discharge Monitoring Report San Onofre Nuclear Generating Station, Unit 1

Dear Mr. Robertus:

The NPDES Discharge Monitoring Report (DMR) for San Onofre Unit I covering the month of January is submitted in accordance with the requirements of Order No. 95-02 (NPDES Permit No. CA0001228). A summary of the generating unit's status and significant analytical results is provided below.

The unit was permanently removed from service in November 1992. All sampled water sources were found to be within permit limits with one exception.

On 1/13/97 at 0900 a sample obtained on the Unit 1 Sewage Treatment Elliuent indicated a settleable solids value of 3.5 ml/1. This was above the instantaneous limit of 3.0 ml/1. The settleable solids condition at the plant returned to limits later that day. The cause of the event was determined to be operator error that resulted in an overaeration event that led to the settleable solids exceedance. It was also determined that there was not enough flocculant addition to the clarifier which resulted in solids floating to the surface of the plant. Corrective actions included the termination of the plant operator and a return to the sewage treatment plant to it's normal mode of operation.

Pursuant to Order No. 95-02, Reporting Requirement 14, the following representative has prepared and is authorized to sign the reports required by this order: Robert K. Heckler, Environmental Engineer.

I certify under penalty oflaw that this document and all attachments were prepared under my 4

direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate._

P.O. N\\128 San Clemente. CA 42tC4-012o I

Mr. Robertus Page 2 Febmary 24,1997 and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations.
