OVERVIEW

1. During the fourth quarter of 2009, discharges occurred from Discharge Paths 001 (once through cooling water), 001B, 001D, 001E, 001F, 001G, 001H, 001J, 001L, 001M, 001 N, 001 P, 002 through 015. No discharges occurred from Discharge Paths 0011, 001 K, 016 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 fourth quarter of 2009, 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 remains below the "No Observable Effect Concentration" (NOEC) at NPDES Discharge 001.

4. A single event during the fourth quarter affected the results of continuous chlorine monitoring for Unit 2 at Discharge 001 on November 6, 2009. A grab sample was taken during the event and analyzed using the Unit 1 monitor. The Unit 2 monitor problem was corrected and it was returned to service before the next injection. The result from the grab sample analysis was used to replace the missing data point.

SUMMARY

OF MONITORING PROGRAM A.

Monitoring of Plant Influent and Effluent

1. The results of the October, November, and December 2009 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 21-25, 2009, is included in Appendix 5. The acute bioassay results show that toxicity was 0.0 TUa (no acute toxicity). Due to the third quarter's test result, the 6-month median is 0.23, which is below the permit limit of 0.26.

3. The laboratory report for one chronic bioassay on water sampled from Discharge 001, performed October 27-29, 2009, 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 ýCentral 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 Program 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, remained below NPDES limitations throughout the quarter.

Both conduits of Unit 1 were treated with simultaneous injections of sodium bromide and sodium hypochlorite six times a day throughout the fourth quarter of 2009 with two brief interruptions in mid-October for maintenance activities.

Unit 2 chemical injections were shut down in early October for the 2R1 5 refueling outage. When Unit 2 circulating water pumps were restarted in early November, simultaneous conduit injections of sodium bromide and sodium hypochlorite six times a day were restarted. These treatments ran uninterrupted throughout the remainder of the fourth quarter.
