Docket No. 50-206 Report of NPDES Permit Violations San Onofre Nuclear Generating Station, Unit 1
References:
Letter from H. W. Newton (SCE) to A. L. Coe (California Regional Water Quality Control Board, l
San Diego Region), NPDES Monitoring Report Unit 1, i
August 2, 1993 This letter transmits a copy of the NPDES monitoring report for San Onofre Nuclear Generating Station (SONGS) Unit 1 for the month of June 1993. This i
letter is being provided in accordance with Section 6.16.2.c of the Technical Specifications to Possession Only License No. DPR-13 for SONGS Unit 1, which i
requires Southern California Edison to report violations of the National j
Pollutant Discharge Elimination System (NPDES) permit to the NRC.
The violation involves the release of a small quantity of Aqueous Film Forming foam (AFFF), which is used as a fire suppressant. AFFF is not listed in the NPDES permit as a constituent of the Unit 1 discharge; therefore, this is being reported as a permit violation.
If you have any questions, please contact me.
Sincerely, h?!

SUBJECT:
NPDES Discharge Monitoring Report h
San Onofre Nuclear Generating Station, Unit 1 Dear Mr. Coe The NPDES Discharge Monitoring Report (DMR) for San Onofre Unit 1 covering the month of June is submitted in accordance with the requirements of Order No.88-001 (NPDES Permit No. CA0001228).
A surmary of the generating unit's status and significant i
analytical results is provided below.
'i The unit was permanently removed from service in November 1992.
All sampled water sources were found to be within permit limits.
l On June 8, 1993, some Aqueous Film Forming Foam (AFFF) was inadvertently released to the Unit 1 Yard Drain Sump from a test e
conducted that day.
Although biodegradable and non-hazardous, j
AFFF is not currently identified as a constituent of the discharge in the Unit 1 NPDES Permit.
However, AFFF has been discussed with your staff in the past and was detailed in our amendment letter submitted to your office on June 2 of this year.
The Yard Drain Sump was isolated and treated with approximately 10 gallons of defoaming agent.
Small quantities of foam reached the Unit 1 Intake Structure and was subsequently discharged.
{
Actions have been taken to prevent such releases like this in the future.
All other tests to date were successful in preventing any discharge of AFFF to the storm drain system.
Pursuant to Order No.88-001, Reporting Requirement 12, the following representative has prepared and is authorized to sign the reports required by this order:
Robert K.
- Heckler, Environmental Engineer.
