procedure and appropriate steps to ensure adequate support is available to minimize the potential of future recurrence.

SUMMARY

OF MONITORING PROGRAM A.

Monitoring of Plant Influent and Effluent

1.

The results of the October, November, and December 2003 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 001, performed October 9-13, 2003, is included in Appendix 5. The bioassay results show that acute toxicity was 0.00 (no mortality).

3.

The laboratory report for one chronic bioassay on water sampled from Discharge 001, performed October 9 - 11, 2003, is included in Appendix 6. The bioassay results show that chronic toxicity was 1.0 (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 fourth quarter continued under the Diablo Canyon Receiving Water Monitoring Program (RWMP) 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-99-503) from PG&E dated January 8, 1999. This program includes tasks from the Ecological Monitoring Program (EMP) with additional stations and increased sampling frequencies.

This program 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 their periodic report for this program.

C.

Acti-Brom Treatment Program Diablo Canyon Power Plant is continuing its use of the proprietary chemical Acti-Brom to control the growth of macrofouling organisms in its main circulating water conduits.

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 Acti-Brom in combination with sodium hypochlorite (NaOCI). Each injection attempts to achieve a target concentration of 200 parts per billion Total Residual Oxidant (TRO) when measured at the inlet waterbox of the condenser.

Discharge TRO, measured at the plant outfall, remained below NPDES limitations.

Unit 1 continued simultaneous sodium hypochlorite and Acti-Brom treatment six times daily throughout the fourth quarter with a brief interruption in December for a saltwater leak search.

Six times daily throughout the fourth quarter conduit 2-1 received simultaneous sodium hypochlorite and Acti-Brom treatments, while conduit received treatments of sodium hypochlorite and sodium bromide. There were brief interruptions in October for injection system pipe repairs and in December due to storm waves.

OVERVIEW

1. During the fourth quarter of 2003, discharges occurred from Discharge Paths 001 (once through cooling water), 001B, 001D, 001E, 001F, 001G, 001H, 001L, 001M, 001N, 001P, 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. California Ocean Plan Table B substances that were not analyzed for were not added to the discharge stream. 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 and amended application in 2001. There have been no changes in the activities conducted at the plant that would have significantly affected the results previously reported in the renewal and amended applications.

3. During the fourth quarter of 2003, maintenance activities that required draining of closed cooling water systems were performed and are summarized below. PG&E received concurrence from the CCRWQCB in a letter dated July 19, 1995, (PG&E Letter DCL-95-156) regarding the use of glutaraldehyde and isothiazolin to control microbiological growth and corrosion in PG&E's closed cooling water systems.

Discharges are drained at a flowrate such that the chronic toxicity level is below the "No Observable Effect Concentration" (NOEC) at NPDES Discharge 001.

(mg/l) 12/08/03 Unit 1 CCW 1000 143 0

4. Because there was no 001 M discharge in October, 001 M Oil and Grease sample was collected in November rather than in October.

5. October composite samples for 001 D were collected as required and picked up for analysis by an ELAP Certified contract laboratory. The composite consisted of nine aliquots. In November, it was discovered that the contract lab had only analyzed five of the nine aliquots. By the time the contract lab located the other four samples, which they misplaced, the samples had exceeded required holding times rendering them invalid for analysis. An additional three aliquots for 001 D were collected and the contract lab analyzed these aliquots in December. The contract lab has written a quality assurance report and reviewed sample-handling procedures with staff to minimize the potential of future occurrence.

6. During the week of 12/29/03, weekly NPDES samples for 001N were not collected.

These samples included the following parameters: total suspended solids, settleable solids, and oil and grease. The previous week, samples collected on 12/23/03 for these parameters were well below NPDES limitations with results of 9 mg/I, ND<0.1 ml/l, and ND<5mg/l, respectively.

Samples collected on 1/5/04 were also well below NPDES limitations with results of 15mg/l, ND<0.1mlA1, ND<5mg/l, respectively. On 1/5/04, there were no observed changes in the treatment plant operation from that of 12/23/03.

Treatment plant flows were lower than normal for this period. Based on this information, the treatment plant is believed to have operated in compliance during the week samples were not collected. The contractor that performs sampling has implemented a new
