OVERVIEW

1. During the first quarter of 2006, discharges occurred from Discharge Paths 001 (once through 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 and number, is provided in Appendix 1.

2. The substances listed in Table B of the 1990 California Ocean Plan were each analyZed for 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 have significantly affected the results previously reported in the 1994 renewal application.

California Ocean Plan Table B substances that were not analyzed for this quarter were not added to the discharge stream.

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

4. During the first quarter of 2006, maintenance activities that required draining of closed cooling water systems were performed and are summarized below. PG&E received 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 to control 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'ow the 'No Observable Effect Concentration" (NOEC) at NPDES Discharge 001.

5. Continuous chlorine monitoring at Discharge 001 was interrupted during the first quarter of 2006 four times. For each interruption, an engineering evaluation was completed in accordance 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 corrective action(s) are tabulated below. In each case, an engineering evaluation was performed using the recorded injection rates and waterbox chlorine results to calculate estimates of chlorine concentration for the affected unit at Discharge 001. These estimates are used to replace results affected by the respective monitor problem as agreed with CCRWQCB staff. Because injection rates are always set to provide a minimal amount of detectable chlorine, the results from the engineering evaluation were all 20 pg/L or more below the applicable 89-pg/L discharge limit.

6. On January 12, 2006, chemical drain tank 0-2 (CDT 0-2) was discharged. A sample from the tank was analyzed using hexane extraction to measure oil and grease content.

T-he result was 26 mg/L of hexane-extractable material. This value apparently exceeded the monthly and daily limits (15 mg/L and 20 mg/L, respectively) for oil and grease for discharge pathway 001 D and is being reported in the attached discharge monitoring forms. However, the result is believed to be a false positive due to the presence of liquid scintillation (LS) solution in the CDT and the sample. Prior to extraction, it was identified that the sample had a whitish tint. This tint is believed to have been caused by a small amount of waste LS solution that had entered the tank during rinsing of residue from bulk solution containers before disposal. The practice of segregating the waste LS solution for separate disposal has been used since May 2005 when LS solution was found to give false positive results from samples extracted with hexane to measure oil and grease.

Five CDT samples had been extracted using the hexane method subsequent to May 2005, with no results greater than 9 mg/L, and the improved laboratory processes for managing LS solution were believed to have eliminated the potential for biased positive results. However, rinsing of empty bulk containers was not specifically addressed, and the 26 mg/L value is believed to be a result of this practice. Permanent postings have been installed in the Chemistry laboratory to prohibit rinsing of any container that contained LS solution into the CDTs. During the remainder of the quarter, eight follcw-up samples have been taken and analyzed using the hexane extraction method. The highest result of these follow-up samples was 5.1 mg/I. Regional Water Control Board staff were notified on January 19, 2006 regarding the CDT 0-2 issue, and correspondence regarding the LS solution was forwarded on February 21, 2006.

6. During routine preventative maintenance on March 29, 2006, the discharge temperature recorder for Unit 2 was found to be high out of tolerance. The recorder was adjusted and retested. Subsequent data was within specifications. A review of historical temperature data indicated that the recorder may have been out of tolerance since the end of the Unit 1 refueling outage (early December 2005). Since that time Unit 2 discharge temperatures have averaged about 2 degrees F above Unit 1 values.

Therefore, actual discharge temperatures and differential temperatures were slightly lower than the values that had been reported for December 2005 and for the values being reported in this report (for January, February and March of 2006). The reported values are slightly inaccurate in a conservative direction, therefore there were no exceedences 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 effluent monitoring are 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 Cl01, performed February 16-20, 2006, is included in Appendix 5. The bioassay results show that acute toxicity was 0.00 TUa (no mortality).

3. The laboratory report for one chronic bioassay on water sampled from Discharge 001, performed February 15-17, 2006, is included in Appendix 6. The bioassay results 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 quarter continued under the Diablo Canyon Receiving Water Monitoring Program (RWM1P) as requested in a letter from the Central Coast Regional Water Quality Control Board (CCRWQCB) dated December 9, 1998, and as detailed in a letter (DCL 503) from PG&E dated January 8, 1999. This program includes tasks from the Ecological Monitoring Program (EMP) with additional stations and increased sampling frequencies. The RWMP replaces the EMP and the Thermal Effects Monitoring Program (TEMP).

2.

In Situ Bioassay Results of the Mussel Watch Program will be reported to the CCRWQCB directly from the California Department of Fish and Game in the Department's periodic report for this program.

C.

Sodium Bromide Treatment Program Diablo Canyon Power Plant is continuing the use of generic sodium bromide to control macrofouling growth for both Units. Both circulating water conduits of each Unit can be chemically treated simultaneously. Each treated conduit typically receives a twenty-minute injection every four hours (six injections a day) of sodium bromide in combination with sodium hypochlorite (NaOCI). Each injection attempts to achieve a target concentration of 200 parts per billion (ppb) Total Residual Oxidant (TRO) when measured at the inlet waterbox of the condenser. Discharge TRO, measured at the plant outfall, remains below NPDES limitations.

Both conduits of Unit 1 were treated with simultaneous injections of sodium bromide and sodium hypochlorite six times a day throughout the first quarter of 2006. There were no interruptions in the treatment schedule.

Both conduits of Unit 2 were treated throughout the first quarter with simultaneous injections of sodium bromide and sodium hypochlorite six times a day until late March when sodium bromide injections were turned off in anticipation of the 2R1 3 refueling outage. Microfouling injections of sodium hypochlorite continued six times a day throughout the remainder of the first quarter.
