OVERVIEW

1. During the first quarter of 2006, discharges occurred from Discharge Paths 001 (oncethrough cooling water), 001 B, 001 D, 001 E, 001 F, 001 G, 001 H, 001 L, 001 M, 001 N,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. 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'sprobability of exceeding NPDES permit limitations.

4. During the first quarter of 2006, maintenance activities that required draining of closedcooling water systems were performed and are summarized below. PG&E receivedconcurrence from the CCRWQCB in response to letters dated July 19,1995 (PG&ELetter 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 DCPP's closed cooling water systems.Discharges are drained at a flow rate such that the chronic toxicity level would be be'owthe 'No Observable Effect Concentration" (NOEC) at NPDES Discharge 001.

5. Continuous chlorine monitoring at Discharge 001 was interrupted during the first quarterof 2006 four times. For each interruption, an engineering evaluation was completed inaccordance with PG&E's January 5, 1994, letter as authorized by the CCRWQCB.Intervals, the affected monitor(s), number of affected results, the cause, and correctiveaction(s) are tabulated below. In each case, an engineering evaluation was performedusing the recorded injection rates and waterbox chlorine results to calculate estimates ofchlorine concentration for the affected unit at Discharge 001. These estimates are usedto replace results affected by the respective monitor problem as agreed with CCRWQCBstaff. Because injection rates are always set to provide a minimal amount of detectablechlorine, the results from the engineering evaluation were all 20 pg/L or more below theapplicable 89-pg/L discharge limit.

6. On January 12, 2006, chemical drain tank 0-2 (CDT 0-2) was discharged. A sample fromthe tank was analyzed using hexane extraction to measure oil and grease content. T-heresult was 26 mg/L of hexane-extractable material. This value apparently exceeded themonthly and daily limits (15 mg/L and 20 mg/L, respectively) for oil and grease fordischarge pathway 001 D and is being reported in the attached discharge monitoringforms. However, the result is believed to be a false positive due to the presence of liquidscintillation (LS) solution in the CDT and the sample. Prior to extraction, it was identifiedthat the sample had a whitish tint. This tint is believed to have been caused by a smallamount of waste LS solution that had entered the tank during rinsing of residue from bulksolution containers before disposal. The practice of segregating the waste LS solutionfor separate disposal has been used since May 2005 when LS solution was found to givefalse positive results from samples extracted with hexane to measure oil and grease.Five CDT samples had been extracted using the hexane method subsequent to May2005, with no results greater than 9 mg/L, and the improved laboratory processes formanaging LS solution were believed to have eliminated the potential for biased positiveresults. However, rinsing of empty bulk containers was not specifically addressed, andthe 26 mg/L value is believed to be a result of this practice. Permanent postings havebeen installed in the Chemistry laboratory to prohibit rinsing of any container thatcontained LS solution into the CDTs. During the remainder of the quarter, eight follcw-upsamples have been taken and analyzed using the hexane extraction method. Thehighest result of these follow-up samples was 5.1 mg/I. Regional Water Control Boardstaff were notified on January 19, 2006 regarding the CDT 0-2 issue, andcorrespondence regarding the LS solution was forwarded on February 21, 2006.

6. During routine preventative maintenance on March 29, 2006, the discharge temperaturerecorder for Unit 2 was found to be high out of tolerance. The recorder was adjustedand retested. Subsequent data was within specifications. A review of historicaltemperature data indicated that the recorder may have been out of tolerance since theend of the Unit 1 refueling outage (early December 2005). Since that time Unit 2discharge temperatures have averaged about 2 degrees F above Unit 1 values.Therefore, actual discharge temperatures and differential temperatures were slightlylower than the values that had been reported for December 2005 and for the valuesbeing reported in this report (for January, February and March of 2006). The reportedvalues are slightly inaccurate in a conservative direction, therefore there were noexceedences of NPDES temperature limits.

SUMMARY OF MONITORING PROGRAM

A. Monitoring of Plant Influent and Effluent

1. The results of the January, February, and March 2006 plant influent and effluentmonitoring are reported on Discharge Self Monitoring Report (DSMR) forms inAppendices 2, 3, and 4, respectively.

2. The laboratory report for one acute bioassay on water sampled from Discharge Cl01,performed February 16-20, 2006, is included in Appendix 5. The bioassay resultsshow that acute toxicity was 0.00 TUa (no mortality).

3. The laboratory report for one chronic bioassay on water sampled from Discharge001, performed February 15-17, 2006, is included in Appendix 6. The bioassayresults show that chronic toxicity was 1.0 TUc (no chronic toxicity).

B. Monitoring of Receiving Waters

1. Ecological Studies at Diablo Canyon

Ecological studies in the vicinity of Diablo Cove conducted during the first quartercontinued under the Diablo Canyon Receiving Water Monitoring Program (RWM1P)as requested in a letter from the Central Coast Regional Water Quality ControlBoard (CCRWQCB) dated December 9, 1998, and as detailed in a letter (DCL-99-503) from PG&E dated January 8, 1999. This program includes tasks from theEcological Monitoring Program (EMP) with additional stations and increasedsampling frequencies. The RWMP replaces the EMP and the Thermal EffectsMonitoring 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 the Department's periodicreport for this program.

C. Sodium Bromide Treatment Program

Diablo Canyon Power Plant is continuing the use of generic sodium bromide to controlmacrofouling growth for both Units. Both circulating water conduits of each Unit can bechemically treated simultaneously. Each treated conduit typically receives a twenty-minute injection every four hours (six injections a day) of sodium bromide in combinationwith sodium hypochlorite (NaOCI). Each injection attempts to achieve a targetconcentration of 200 parts per billion (ppb) Total Residual Oxidant (TRO) whenmeasured at the inlet waterbox of the condenser. Discharge TRO, measured at theplant outfall, remains below NPDES limitations.

Both conduits of Unit 1 were treated with simultaneous injections of sodium bromide andsodium hypochlorite six times a day throughout the first quarter of 2006. There were nointerruptions in the treatment schedule.

Both conduits of Unit 2 were treated throughout the first quarter with simultaneousinjections of sodium bromide and sodium hypochlorite six times a day until late Marchwhen sodium bromide injections were turned off in anticipation of the 2R1 3 refuelingoutage. Microfouling injections of sodium hypochlorite continued six times a daythroughout the remainder of the first quarter.
