OVERVIEW

1. During the third quarter of 2006, discharges occurred from Discharge Paths 001 (once through cooling water), 001B, 001D, 001E, 001 F, 001G, 001H, 001J, 001L, 001M, 001 N, 001 P, 002, 003, 004, 006, and 013. No discharges occurred from Discharge Paths 0011, 001 K, 005, 007 through 012, and 014 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 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 well below the "No Observable Effect Concentration" (NOEC) at NPDES Discharge 001.

Date System Volume Glutaraldehyde Isothiazolin (gallons) (mgll) (mgll) 7/20/06 Unit 1 SCW 33,000 100 3.2 8/17/06 Unit 1 ICW 3,300 201 2.8 9/8/06 Unit 2 SCW 33,000 157 6.0 9/15/06 Unit 1 SCW 60 55 1.0 9/19-20/06 Unit 1 CCW 180,300 215 0.0

4. On July 27, 2006 a pipe leading from the seawater reverse osmosis unit burst along the roadway leading up to the raw water storage reservoirs, sending freshwater into Discharge Path 006. Upon discovery, active measures were taken to prevent erosion and sediment from entering the storm water drainage ditch and ocean outfall. Flow was stopped and the pipe was repaired by the end of the day on July 28. It is estimated that a maximum of 2,000 gallons of freshwater was released. The description in the NPDES permit includes only rainwater for Discharge 006. Even though the released water was pure freshwater, technically it is not rainwater and Regional Water Quality Control Board staff were notified on July 28, 2006.

5. Continuous chlorine monitoring at Discharge 001 was interrupted three times during the third quarter of 2006. For these interruptions, engineering evaluations were 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. An engineering evaluation was performed using the recorded chemical injection rates and condenser waterbox inlet Total Residual Oxidant (TRO) 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 per the letter agreement with CCRWQCB staff. Injection rates are set to provide a minimal amount of detectable chlorine at the Discharge. Results from the engineering evaluations were all at least 20 pg/L below the applicable 89-p1g/L discharge limit.

Interval Affected Number of Cause Corrective Monitor(s) Affected Actions Readings 07/20/06 Plankton fouling of the Replaced monitor flow to Unit 1 35 block, and increased 7/27/06 piping flush frequency.

08/10/06 Unit 1 2 Low reagent. Replaced reagent.

08/10/06 Unit 2 1 Calibration problem. Re-calibrated monitor.

SUMMARY

OF MONITORING PROGRAM A. Monitoring of Plant Influent and Effluent

1. The results of the July, August, and September 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 001, performed August 2-6, 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 August 3-5, 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 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 (PG&E Letter DCL-99-503) 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 Proqram 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 (NaBr) 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 of 2006. There were brief interruptions in the treatment schedule in late July, August and September due to a flow alarm system trip, depletion of sodium bromide chemical stock due to supply delays, and piping maintenance activities.

Both conduits of Unit 2 were treated with simultaneous injections of sodium bromide and sodium hypochlorite six times a day throughout the third quarter of 2006. There were brief interruptions in the treatment schedule in late July, August and September due to a flow alarm system trip, depletion of sodium bromide chemical stock due to supply delays, and piping maintenance activities.
