Subject:
Docket Nos. 50-361and 50-362 Report of NPDES Permit Limit Violation San Onofre Nuclear Generating Station (SONGS), Units 2 and 3
Dear Sir or Madam:
On January 11, 2005, a release of resin from the High Flow Make-up Demineralizer (HFMUD) resulted in a total suspended solids concentration of 394 mg/l, which exceeded the instantaneous maximum 100 mg/A limit. Samples obtained the following day, on a subsequent release, indicated a return to limits. Southern California Edison (SCE) reported this occurrence to the California Regional Water Quality Control Board (RWQCB), San Diego Region by letters dated February 22, 2005 (see attached letters).
SONGS Units 2 and 3 Facility Operating Licenses (Nos. NPF-10 and NPF-15), Appendix B, Section 3.2, require violations of the National Pollution Discharge Elimination System (NPDES)
Permit or State certification (pursuant to Section 401 of the Clean Water Act), to be reported to the NRC by submitting copies of the reports required by the NPDES Permit or certification.
Accordingly, copies of the report submitted to the RWQCB are provided as attachments to this letter.
If you have any questions, please contact Mr. Clay E. Williams at (949) 368-6707.

SUBJECT:
NPDES January 2005 Discharge Monitoring Report Clarification San Onofre Nuclear Generating Station, Units 2 & 3
Dear Mr. Robertus:
This letter is to clarify the January 2005 cover letters for the monthly discharge monitoring reports for Units 2 and 3 (NPDES PermitNumbers CA0108073 and CAOIOS181). The cover letters stated that the high total suspended solids (TSS) release at the High Flow Make-up Demineralizer (IFMUD) occurred on 1110105 and returned to limits on 1/11105. The data in the discharge monitoring reports has the correct dates of 1/11/05 and 1/12/05 respectively. If you have any questions, please contact Robert Heckler at (949) 368-6816.

SUBJECT:
NPDES January 2005 Discharge Monitoring Report San Onofre Nuclear Generating Station, Unit 2
Dear Mr. Robertus:
SCE submits the subject report in accordance with the requirements of Order No. 99-47 (NPDES Permit No. CA0 108073). All sampled water sources were found to be within permit limits with one exception. On 1/10/05, a release of resin from the High Flow Make-Up Dermineralizer (HFMUD) resulted in a total suspended solids concentration of 394 mg/L. This exceeded the instantaneous maximum limit of 100 mg/l. Samples obtained on 1/11/05 on a subsequent release indicated a return to limits. The release was caused by a mispositioned valve which resulted in a carryover of resin to the outfall. Since this event, training has been conducted and design changes are being considered to prevent reoccurance in the future.
Pursuant to Order No. 99-47, Reporting Requirement 10, 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 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.

SUBJECT:
NPDES January 2005 Discharge Monitoring Report Clarification San Onofre Nuclear Generating Station, Units 2 & 3
DearMr. Robertus:
This letter is to clarify the January 2005 cover letters for the monthly discharge monitoring reports for Units 2 and 3 (NPDES PermitNumbers CA0108073 and CA0108181). The cover letters stated that the high total suspended solids (TSS) release at the High Flow Make-up Demineralizer (HFMUD) occurred on 1/10/05 and returned to limits on 1/11/05. The data in the discharge monitoring reports has the correct dates of 1/11/05 and 1/12/05 respectively. If you have any questions, please contact Robert Heckler at (949) 368-6816.
Sincerely, H.Newto~

SUBJECT:
NPDES January 2005 Discharge Monitoring Report San Onofre Nuclear Generating Station, Unit 3
Dear Mr. Robertus:
SCE submits the subject report in accordance with the requirements of Order No. 99-48 (NPDES PermitNo. CA0108181). All sampled water sources were found to be within permit limits with one exception. On 1/10/05, a release of resin from the High Flow Make-Up Demineralizer (HFMUD) resulted in a total suspended solids concentration of 394 mg/L. This exceeded the instantaneous maximum limit of 100 mg/I. Samples obtained on 1/11/05 on a subsequent release indicated a return to limits. The release was caused by a mispositioned valve which resulted in a carryover of resin to the outfall. Since this event, training has been conducted and design changes are being considered to prevent reoccurance in the future.
Pursuant to Order No. 9948, Reporting Requirement 10, 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 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.

Chlorine Sample Calculations San Onofre Units 2 and 3 chlorinate four times per day for each unit at a duration of 25 minutes.
The instantaneous limit for total residual chlorine is therefore calculated using the equation in the NPDES permits for each unit under discharge specification B..1 as follows:
log y = -0.43(0og x) + 1.8 Where y = the water quality objective (in ug/1) to apply when chlorine/bromine is being discharged x = the duration of uninterrupted chlorine/bromine discharge in minutes The result of the above formula must be multiplied by a dilution factor to arrive at the time.
weighted effluent discharge limit. In the case of San Onofre Units 2 and 3, this dilution factor equals 11.
The USEPA BAT effluent limitation contained in 40 CFR 423 is 0.20 mg/L.
To obtain the instantaneous limit under discharge specification B.1 for San Onofre Units 2 and 3,you can calculate as follows:
log y = -0.43(log 25) + 1.8 Logy = 1.9889 y= 15.808(11) = 173.89 ug/h converting to mg/l 173.89/1000 = 0.174 mg/i for a 25 minute chlorination duration The MER limit (lb/dayj = 8.34 x C x Q x Z/24 where C = effluent concentration limit as calculated above (mg/I)
Q = discharge flowrate (MGD)
Z = total time (hours of chlorine/bromine is discharged per day)
For Unit 2 in the month of January 2005, the limit would be calculated as follows:
MER limit (lbs/day) = 8.34(0.08)(1218.706)(2/24) = 67.76 lb/day (for sample on 1/10/05)
For Unit 3 in the month of January 2005, the limit would be calculated as follows: .
MER limit (lbs/day) = 8.34(0.02)(1218.656)(2/24) 16.94 lb/day (for sample on 1/10/05)
