Subject:

Docket No. 50-362 Report of NPDES Permit Limit Violation San Onofre Nuclear Generating Station (SONGS), Unit 3

Reference:

Letter, Mary Jane'Johnson (SCE) to David Gibson (California Regional Water Quality Control Board [CRWQCB]), "NPDES April 2010 Discharge Monitoring Report" May 25, 2010

Dear Sir or Madam:

SONGS Unit 3 Facility Operating Licenses (No. NPF-1 5), Appendix B, Section 3.2, requires violations of the National Pollution Discharge Elimination System (NPDES) Permit to be reported to the NRC by submitting copies of the reports required by the NPDES Permit.

By the Reference above, Southern California Edison (SCE) reported to the California Regional Water Quality Control Board (CRWQCB) that the Mesa Sewage Treatment Plant effluent settleable solids monthly average for April 2010 exceeded the limit (1.2ml/I actual vs. 1.0 mi/l limit) allowed by the Unit 3 NPDES permit (number CA0108181). The Mesa Sewage Treatment Plant effluent exceedance is detailed in the attached letter and discharge monitoring report mailed to the San Diego Regional Water Quality Control Board dated May 25, 2010.

If you have any questions, please contact Mr. Clay E. Williams at (949) 368-6707.

Sincerely,

Attachment:

As stated.

SUBJECT:

NPDES April 2010 Discharge Monitoring Report San Onofre Nuclear Generating Station, Unit 3

Dear Mr. Gibson:

SCE submits the subject report in accordance with the requirements of Order No. R9-2005-0006 (NPDES Permit No. CA01081 81). All sampled water sources were found to be within permit limits, except the Mesa sewage treatment average settleable solids. The monthly sample was collected close to the completion of plant cleaning maintenance. This maintenance had stirred up the clarifier enough that solids escaped over the weir. The sample was also collected too late in the month to allow additional samples to factor into the average, thus this single samp'lee represents the average. The Mesa Sewage Treatment Plant average settleable solids returned to compliance on May 11, 2010. We are currently evaluating the apparent cause so that a solution for long term compliance can be developed. The results of this evaluation will be discussed in the May report. The attached discharge monitoring reports are in the format requested in your January 7, 2008 letter.

Pursuant to Order No. R9-2005-0006, State and Federal Standard Provisions, Section E, the following representative has prepared and is authorized to sign the reports required by this order:

Arthur Kneisel, Environmental Technical Specialist.

I certify under penalty of law that this document and all attachments were prepared under my 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 and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations.
