OVERVIEW

. During the second quarter of 2005, discharges occurred from Discharge Paths 001(once through cooling water), 001B, 001D, 001E, 001F, 001G, 001H, 001L, 001M,001N, 001P, and 002 through 016. No discharges occurred from Discharge Paths 0011,001J, 001K, and 017. A list of all of the permit discharge pathways, including name andnumber, is provided in Appendix 1.

2. The-substances listed in Table B of the 1990 California Ocean Plan were each analyzedfor and reported in the permit renewal application for Diablo Canyon submitted in 1994.There have been no changes in the activities conducted at the plant that would havesignificantly affected the results previously reported in the 1994 renewal application.California Ocean Plan Table B substances that were not analyzed for this quarter werenot added to the discharge stream.

3. During the second quarter of 2005, maintenance activities that required draining ofclosed cooling water systems were performed and are summarized below. PG&Ereceived concurrence from the CCRWQCB in response to letters dated July 19, 1995(PG&E Letter DCL-95-156), May 23, 1996 (PG&E Letter DCL-96-522), and May 19,1997 (PG&E Letter DCL-97-533) regarding the use of glutaraldehyde and isothiazolin tocontrol microbiological growth and corrosion in PG&E's closed cooling water systems.Discharges are drained at a flow rate such that the chronic toxicity level would be belowthe "No Observable Effect Concentration" (NOEC) at NPDES Discharge 001.

4. Injections of sulfur hexafluoride (SF6) into DCPP's condensers were performed to detectsaltwater leaks during this quarter. CCRWQCB's Sorrel Marks concurred duringconversations held in May 1996 that periodic use of SF6 would not increase DCPP's .probability of exceeding NPDES permit limitations.

5. On May 10, 2005, oil and grease analysis of a sample from chemical drain tank 0-1(CDT 0-1) by hexane extraction gave a result of 67 mg/L. This value apparentlyexceeded the monthly and daily limits (15 mg/L and 20 mgIL, respectively) for dischargepathway 001D. The CDT 0-1 had been discharged on April 10, 2005 based on theresult of freon extraction analysis performed at that time which gave a non-detect result.Investigation showed that the greater result had been caused by the presence of liquidscintillation (LS) cocktail in the sample. The LS cocktail had been approved for disposalin the CDT based on its MSDS. However, the material's chemical composition makes itpartially extractable by the hexane analysis for oil and grease. This was verified byaddition of a known amount of LS cocktail to a sample, followed by hexane extraction.Back calculation of the amount of cocktail in the CDT based on the recovery of theknown addition agreed with the actual composition of the tank. For this reason, the 67mgIL value has been determined to be a false positive result for oil and grease.Regional Water Quality Control Board staff was notified of the issue on May 11, 2005.To prevent recurrence of this event, all waste LS cocktail is being segregated fordisposal by incineration at an approved off-site facility.

6. On May 19, 2005, the result for the weekly Unit 2 discharge chlorine monitor qualitycontrol sample was less than the lower control limit. An engineering evaluation wasperformed, and the results for the previous week corrected based on the findings. All ofthe corrected results were well below the applicable discharge limit (89 pg/L).Investigation showed that the reagent pump in the chlorine monitor was not deliveringconsistently at the required rate, and that this had caused the observed low bias. Thepump was replaced, and the monitor has been operating correctly.

SUMMARY OF MONITORING PROGRAM

A. Monitoring of Plant Influent and Effluent

1. The results of the April, May, and June 2005 plant influent and effluent monitoringare reported on Discharge Self Monitoring Report (DSMR) forms in Appendices 2,3, and 4, respectively.

2. The laboratory report for one acute bioassay on water sampled from Discharge 001,performed May 4 - 8, 2005, is included in Appendix 5. The bioassay results showthat acute toxicity was 0.00 TUa (no mortality).

3. The laboratory report for one chronic bioassay on water sampled from Discharge001, performed May 5 - 7, 2005, is included in Appendix 6. The bioassay resultsshow that chronic toxicity was 1.0 TUc (no chronic toxicity).

B. Monitorinq of Receiving Waters

1. Ecological Studies at Diablo Canyon

Ecological studies in the vicinity of Diablo Cove conducted during the secondquarter continued under the Diablo Canyon Receiving Water Monitoring Program(RWMP) as requested in a letter from the Central Coast Regional Water QualityControl Board (CCRWQCB) dated December 9, 1998 and as detailed in a letter(DCL-99-503) from PG&E dated January 8, 1999. This program includes tasksfrom the Ecological Monitoring Program (EMP) with additional stations andincreased sampling frequencies. This program replaces the EMP and the ThermalEffects Monitoring Program (TEMP).

2. In Situ Bioassay

Results of the Mussel Watch Program will be reported to the CCRWQCB directlyfrom the California Department of Fish and Game in their periodic report for thisprogram.

C. Sodium Bromide Treatment Program

After a test comparing proprietary Acti-Brom and generic sodium bromide, DiabloCanyon Power Plant has discontinued the use of the proprietary Acti-Brom to control thegrowth of macrofouling organisms in its main circulating water conduits. Genericsodium bromide has been used for macrofouling control for both Units since the middleof July 2004. Both circulating water conduits of each Unit can be chemically treatedsimultaneously. Each treated conduit typically receives a twenty-minute injection everyfour hours (six injections a day) of sodium bromide in combination with sodiumhypochlorite (NaOCI). Each injection attempts to achieve a target concentration of 200

parts per billion Total Residual Oxidant (TRO) when measured at the inlet waterbox ofthe condenser. Discharge TRO, measured at the plant outfall, remains below NPDESlimitations.

Both conduits of Unit 1 were treated through the second quarter with simultaneousinjections of sodium bromide and sodium hypochlorite six times a day. There were briefinterruptions in early April and June for routine maintenance activities.

Both conduits of Unit 2 were treated through the second quarter with simultaneousinjections of sodium bromide and sodium hypochiorite six times a day with one briefinterruption in treatment in early April due to routine maintenance activities.
