OVERVIEW

1. During the fourth quarter of 2005, 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, 001 K, 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. The primary discharge points (001, 002, 003, 004) were sampled and analyzed for several parameters by a certified laboratory contractor in November. This was done mainly to provide updated comprehensive data for the ongoing Diablo Canyon NPDES permit renewal process. Where applicable, results are included in the November DSMR.

4. During the fourth 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.

Date System Volume Glutaraldehyde Isothiazolin (gallons)

(mg/i)

(Mg/l)

10/26/05 Unit 1 SCW 465 269 1.8 to 11/26/05 10/27/05 Unit 1 SCW 25 198 1.8 11/08/05 Unit 1 SCW 15 269 1.8 12/14/05 Unit 2 SCW 33,000 162 8.6

The release from 10/26/05 to 11126/05 was due to a leaking valve that resulted in a release of 15 gallons per day for 31 days for a total of 465 gallons.

4. An error at a contract laboratory resulted in the analysis of the suspended solids sample from discharge 001 N being performed one day after the allowed 7-day holding time.

The sample was taken on October 6, 2005 and was received at the contract laboratory for analysis on the same day. This was the second event of this type since July 1, 2005.

The laboratory was requested to identify their corrective actions to prevent reoccurrence. Their response was received on 12/2/05, and more documented attention to detail has been observed in that laboratory's reports.

5. In early October, condensate from Unit I was drained prior to maintenance on the system through discharge point 001 F instead of 001J. This is the isolated section of the condensate system that cannot be drained via the normal pathway of 001J. The volume of this drainage was estimated at less than 2000 gallons, of which the majority was

received by the turbine building sump that was ultimately released via discharge point 001 F. A fraction of the volume was also received by the hold-up sump that seasonally discharges via point 009. Analysis results for total suspended solids and oil and grease from a representative sample before the system was drained were less than the respective method detection limits of 1.4 and 0.5 mg/L, respectively.

6. On January 6, 2006, the result for the weekly QC check at the continuous chlorine monitor on Unit 1 at the 001 discharge was observed to be less than the lower acceptance limit for this test. This required an engineering evaluation to verify the accuracy of Unit 1 chlorine values in late December. This engineering evaluation was performed for total residual chlorine back to the successful QC check on December 28, 2005. Conservative estimates from this evaluation were used to replace any questionable readings from the monitor. All of the actual or estimated results were well below the applicable discharge limit of 89 pg/L.

SUMMARY

OF MONITORING PROGRAM A.

Monitoring of Plant Influent and Effluent

1. The results of the October, November, and December 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 October 26-30, 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 October 27 - 29, 2005, 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. 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 Proaram 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 for the first 10 days of October 2005 when sodium bromide injections were shut down. M/icrofouling injections of sodium hypochlorite continued six times a day until October 21, 2005 when injections were shut down in preparation for the I RI 3 refueling outage. Simultaneous injections of sodium hypochlorite and sodium bromide were restarted near the end of November 2005 and continued through the rest of the quarter with one brief interruption due to dechlorination injection pump problems.

Both conduits of Unit 2 were treated throughout the fourth quarter with simultaneous injections of sodium bromide and sodium hypochlorite six times a day. There was one brief interruption in October due to operator error.
