OVERVIEW

1. During the first quarter of 2008, discharges occurred from Discharge Paths 001 (once through cooling water), 001B, 001D, 001E, 001F, 001G, 001H, 001J, 001L, 001N, 001P, and 002 through 15. No discharges occurred from Discharge Paths 0011, 001K, 001M, 0161 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. During the first quarter of 2008, 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 below.

4. On January 29, 2008, a level switch malfunction caused the turbine building sump to overflow to discharge, bypassing the oily-water-separator. The turbine building watch discovered the sump overflowing to the clean side, and observed the pump level switches in the normal automatic position. Both sump pumps were immediately manually started, terminating the flow overboard. However, turbine building sump water that had been directly released bypassed the oily water separator described for this discharge pathway (001 F). DCPP conservatively estimates that a maximum of 25 gpm was released for approximately 18.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months resulting in a bypass of up to 27,750 gallons.

Samples of the water remaining in the turbine building sump indicated that values for oil and grease (19.4 mg/I) and total suspended solids (17 mg/I) were below the daily maximum limit for discharge point 001 F. Therefore, this event was determined to be a bypass and not an exceedance. Regional Water Quality Control Board staff were notified within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months of the bypass. Corrective maintenance was performed on the pump switches and satisfactory operation was verified.

5. On February 23, 2008, chlorine levels at the Unit-1 discharge monitor reached 207 ppb during the 1600 injection, exceeding the 200 ppb limit in DCPP's NPDES discharge permit. The exceedance was discovered the morning of February 24, 2008. Regional Water Quality Control Board staff were notified the same day, within the 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months notification period. Investigation indicated that maintenance on the main seawater supply piping for the chemical injection system had taken place earlier on February 2 3 rd.

Pipe cleaning during the maintenance activity resulted in increased seawater flow within the overall system during the 1600 injection. The increased flow and associated water pressure forced out biofouling material that had accumulated and partially blocked system piping downstream of the conduit 1-1 chemical injection point. The restriction of water flow at this point had generated a build-up of treatment chemical that was suddenly released into the conduit when the blockage broke free. Fouled system seawater supply piping had been the cause of another exceedance in August 2007 (reported in the third quarter 2007 report). The system maintenance activity on February 23rd was part of the corrective action implemented in response to the August 2007 exceedance. 'Unfortunately, chemical treatment operations personnel were not notified that the piping was being cleaned, and the system was being put back in service with potentially enhanced seawater flow. Therefore, measures were not initiated (review chemical injection rate settings, conduct system test injections, increase dechlorination rates, etc.) to adequately evaluate potential change in system conditions, and subsequently mitigate related operational problems. To prevent recurrence, plant procedures have been modified to include notification steps during maintenance activities that could result in enhanced seawater flow. Additionally, preventative

)

maintenance periodic work orders have been established to remove biofouling throughout the entire system well before it can cause appreciable pipe occlusion, or contribute to flow restrictions that can result in pockets of chemical accumulation.

SUMMARY

OF MONITORING PROGRAM A.

Monitoring of Plant Influent and Effluent

1. The results of the January, February, and March 2008 plant influent and effluent monitoring are reported on Discharge Self Monitoring Report-(DSMR) forms in Appendices 2, 3, and 4, respectively.

2. Laboratory reports for three acute bioassay on water sampled from Discharge 001, performed January 25-29, 2008, February 6-10, 2008, and March 14-18, 2008, are included in Appendix 5. Acute toxicity testing frequency was increased due to positive results in two tests during the last quarter of 2007 (results were suspect due to unusual circumstances in the tests). Results from all three 2008 acute tests indicate no toxicity (TUa=0.0). With these three first quarter tests, the six month median is 0.0, which is well below the NPDES six month median limit of 0.26.

3. The laboratory report for one chronic bioassay on water sampled from Discharge 001, performed January 25-27, 2008, 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 (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 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, remained below NPDES limitations throughout the 1st quarter except for the single exceedance described previously (Overview Section 5).

Both conduits of Unit-1 were treated with simultaneous injections of sodium bromide and sodium hypochlorite six times a day throughout the first quarter of 2008 with brief interruptions for maintenance activities in mid January and mid to late February.

Both conduits of Unit-2 were treated with simultaneous injections of sodium bromide and sodium hypochlorite six times a day-throughout January 2008 with a brief interruption for maintenance activities in mid January. Unit-2 injections were shut down at the beginning of February for the 2R1 4 refueling outage. Unit-2 injections remained off for the remainder of the first quarter.
