OVERVIEW

1. During the first quarter of 2005, discharges occurred from Discharge Paths 001 (once through cooling water), 001B, 001D, 001E, 001F, 001G, 001H, 001J, 001 L, 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 California Ocean Plan were each analyzed for and reported in 1994 and 2002 in support of permit renewal applications for Diablo Canyon. There have been no changes in the activities conducted at the plant that would have significantly affected the results previously reported in the 1994 and 2002 submittals. California Ocean Plan Table B substances that were not analyzed for this quarter were not added to the discharge stream.

3. During the first 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 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 January 16, 2005 a pipe burst at the onsite reverse osmosis plant releasing purified freshwater at approximately 225 gallons per minute into the ditch leading to storm drain discharge point 005. The pipe burst some time during the night. In the worst case, the release would have lasted 13 hours1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br /> before the rupture was discovered and the water supply was shut down. This would have released a maximum of 175,500 gallons of purified freshwater. The Regional Board staff were notified on January 20, 2005 after PG&E Environmental personnel were informed of the incident.

5. On January 20, 2005, high levels of sand, silt, and organic debris fouling were observed during the weekly flush of the Unit I discharge chlorine monitor. The Unit 1 discharge monitor values increased significantly after the flush. Therefore, an engineering evaluation was performed to ensure that discharge limits were not exceeded during the time that the monitor supply line may have had reduced flow. The evaluation indicated that 16 values may have been affected by reduced flow. However, only one of the conservatively estimated results from the engineering evaluation was a daily maximum and is, therefore, included in this report. This corrected value was 47 ppb, which is well below the calculated effluent limit in the California Ocean of 89 ppb.

6. 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.

SUMMARY

OF MONITORING PROGRAM A.

Monitoring of Plant Influent and Effluent

1. The results of the January, February, and March 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 February 10 - 14, 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 February 24 - 26, 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 first 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 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 (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 through the first quarter with simultaneous injections of sodium bromide and sodium hypochlorite six times a day. There were brief interruptions in early January for a condenser cleaning, in early February for a tunnel cleaning, and in late March for injection system wiring repair.

Both conduits of Unit 2 were treated through the first quarter with simultaneous injections of sodium bromide and sodium hypochlorite six times a day with brief interruptions in treatment in early and late March due to maintenance activities.
