OVERVIEW During the fourth quarter of 2004, discharges occurred from Discharge Paths 001 (once through cooling water), 001B, 001D, 001E, 001F, 001G, 001H, 001J, 001L, 001M, 001N, 001P, and 002 through 016. No discharges occurred from Discharge Paths 0011, 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 Califomia 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. During the fourth quarter of 2004, 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 and another letter dated May 19, 1997 (PG&E Letter DCL-95-156 and PG&E Letter DCL-97-533, respectively) 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 flow rate such that the chronic toxicity level would be below the 'No Observable Effect Concentration' (NOEC) at NPDES Discharge 001.

4. On November 30, 2004, a significant change in the readings from the Unit I discharge chlorine monitor were observed after only a small change in injection rates on November 24, 2004. This inconsistency brought the discharge chlorine results before the shift into question. Tests were run and it was found that the sample supply line to the monitor was partially blocked at an unidentified location and that prior chlorine values had been underestimated. Discharge chlorine concentrations from November 1, 2004 through December 1, 2004 were found to have been affected. The sample supply tubing for the Unit 1 discharge chlorine monitor was completely replaced on December 1, 2004.

Regional Board staff were notified on December 2, 2004 and it was requested that this information be included in the next quarterly report. An engineering evaluation was performed and corrected discharge values placed in the records. The highest value during the period in question was conservatively estimated at 85 ppb (below NPDES and California Ocean Plan limits).

5. During a two week period in December, 2004, Unit 1 dechlorination was not functioning properly. Unit 1 injections were reprogrammed to 10-minute injections twelve times a day to ensure that injections without dechlorination would not exceed California Ocean Plan limits. Based on the 10 minute duration for injections, the calculated effluent limit from the formulas in the California Ocean Plan is 120 ppb. Our highest value at the point of discharge was 101 ppb during this period (below the calculated discharge limit).

Once the problem with dechlorination was repaired, injections were reprogrammed for 20 minute durations six times per day with dechlorination.

6. On December 2, 2004, a small amount of Unit 2 condensate was inadvertently allowed to flow to the clean side of the Unit 2 turbine building sump (Discharge 001 F). This flow was outside the monitored pathway, and continued at about 1 gallon per minute for up to 2 days. The release was stopped upon discovery. A sample of the water was analyzed and all parameters were found to be below NPDES limits (sample results below). The water and its constituents were consistent with DCPP's NPDES permit for discharge 001 F. Regional Board staff were notified on December 3, 2004 and it was requested that this information be included in the next quarterly report.

7. On December 30, 2004, the Unit 1 discharge chlorine monitor did not pass its weekly quality control check. The instrument was satisfactorily recalibrated. An engineering evaluation was performed on the results that had been recorded from the failed check back to the previous successful control check on December 23, 2004, and conservatively estimated results are being reported. The highest corrected value during the period in question was 25 ppb, which is well below the calculated effluent limit in the California Ocean of 89 ppb.

SUMMARY

OF MONITORING PROGRAM A.

Monitoring of Plant lnflu6nt and Effluent

1. The results of the October, November, and December 2004 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 13 - 17, 2004, 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 October 6 - 8, 2004, 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 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 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 After a test comparing Acti-Brom and sodium bromide, Diablo Canyon Power Plant has discontinued the use of the proprietary chemical Acti-Brom to control the growth of macrofouling organisms in its main circulating water conduits. Sodium bromide has been used for macrofouling control for both Units since the middle of July 2004. 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 Total Residual Oxidant (TRO) when measured at the inlet waterbox of the condenser.

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

Unit 1 ran through the fourth quarter with simultaneous injections of sodium bromide and sodium hypochlorite six times a day (with the exception of the two week period during December when twelve ten-minute injections per day were utilized - reference Overview Section 5.) with brief interruptions due to programming and dechlorination issues, and piping maintenance activities.

Conduit 2-1 started the fourth quarter with injections of sodium hypochlorite six times daily for condenser microfouling control, while conduit 2-2 received simultaneous injections of sodium bromide and sodium hypochlorite six times a day. Unit 2 injections were shut down in late Octoberforthe 2R12 refueling outage. Injections were restarted in early December when the circulating water pumps were restarted. Both Unit 2 conduits received simultaneous injections of sodium bromide and sodium hypochlorite six times a day through the remainder of the quarter. There were brief interruptions in treatment for both conduits during the quarter due to maintenance activities.
