PACIFIC GAS AND ELECTRIC COMPANY NUCLEAR POWER GENERATION Third Quarter 2005 REPORT ON DISCHARGE MONITORING AT DIABLO CANYON POWER PLANT (NPDES No. CA0003751)

OVERVIEW

i.

During the third 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 004. No discharges occurred from Discharge Paths 0011, 001J, 001 K, and 005 through 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. During the third quarter of 2005, 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 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. 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.

5. Two samples from flow path 001 D were taken on July 6, 2005 for oil and grease analysis in the Diablo Canyon Power Plant laboratory. These samples were analyzed on August 12, 2005; nine days in excess of the 28-day maximum holding time. When analyzed, the results were a non-detect (<5 mg/L) and 7.4 mg/L. These results are well below both the 15 mg/L monthly average limit, and the 20 mg/L daily maximum limit.

Because the samples had been acidified and refrigerated since collection, it is unlikely that exceedance of the 28-day sample holding time significantly impacted the accuracy of results obtained, or effected the conclusion that oil and grease limits were not exceeded.

6. One sample from flow path 001 N was taken on July 8, 2005 for settleable solids analysis. The sample was received at the contract laboratory where it was to be analyzed later on that same day. However, the analysis was not performed until July 12, 2005; two days in excess of the 48-hour maximum holding time. The result of the

analysis was a non detect (< 0.1 mi/L). It is believed that exceeding the hold time at the laboratory had no significant effect on the result, because detectable settleable solids have not historically been observed in flow path 001 N at Diablo Canyon Power Plant.

Accordingly, it is unlikely that the monthly average limit of 1.0 ml/L or the daily maximum limit of 3.0 ml/L was approached in the sample, and results obtained are accurate.

7. On August 17, 2005, an unusually high Total Suspended Solids (TSS) value of 110 mg/i for 001 N was detected. Other TSS values for 001 N during August were <5 mg/I, 9 mg/I, and 6 mg/I. Therefore, the monthly average for August was well below the limit of 60 mg/A. Since, there is no maximum limit for TSS, and the monthly average remained well below the 60 mg/I limit, DCPP did not exceed the TSS limit during the month of August for 001 N.

SUMMARY

OF MONITORING PROGRAM A.

Monitoring of Plant Influent and Effluent

1. The results of the July, August, and September 2005 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 August 17 - 21, 2005, 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 August 18 - 20, 2005, is included in Appendix 6. The bioassay results show 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 third 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. 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 their periodic report for this program.

C.

Sodium Bromide Treatment Program Diablo Canyon Power Plant is continuing its 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 third quarter. There were two brief interruptions in August due to lack of chemical and operator error.

Both conduits of Unit 2 were treated through most of the third quarter with simultaneous injections of sodium bromide and sodium hypochlorite six times a day. There were two brief interruptions in August due to lack of chemical and operator error, and another longer interruption in mid-September while both Unit 2 conduits were manually cleaned.

D.

Errata Information In Diablo Canyon Power Plant's second quarter report, page M3 of the June DSMR contained an error. The flow-weighted monthly average for total suspended solids at discharge 001D had been incorrectly calculated. The value should have been 5 mg/I, not 11 mg/I as originally reported. A corrected DSMR form is included in Appendix 7.
