OVERVIEW

1. During the first quarter of 2010, discharges occurred from Discharge Paths 001 (once through cooling water), 001 B, 001 D, 001 E, 001 F, 001 G, 001 H, 001 L, 001 M, 001 N, 001P, 002 through 015. No discharges occurred from Discharge Paths 0011, 001J, 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 first quarter of 2010, 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 first quarter affected the results of continuous chlorine monitoring: A plugged air line caused the Unit 2 discharge monitor to miss one injection on March 15, 2010. The plugged air line was cleared and cleaned. Monitoring during subsequent injections was normal. An engineering evaluation of the affected result was completed as authorized by the Regional Board in accordance with PG&E's January 5, 1994 letter. The Engineering evaluation was based on recorded chemical injection rates and condenser waterbox inlet chlorine monitoring results. These factors were used to calculate an estimate of actual chlorine concentration at Discharge 001 during the missed monitoring event. The estimate (62-pg/L) was then used as the value for the missing data point. The result from the engineering evaluation was below the applicable 89-pg/L discharge limit.

SUMMARY

OF MONITORING PROGRAM A.

Monitoring of Plant Influent and Effluent

1. The results of the January, February, and March 2010 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 January 13-17, 2010, is included in Appendix 5. The acute bioassay results show that toxicity was 0.0 TUa (no acute toxicity).

3. The laboratory report for one chronic bioassay on water sampled from Discharge 001, performed January 13-15, 2010, 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 Program Diablo Canyon Power Plant is continuing the use of generic sodium bromide and sodium hypochlorite 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.

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 through the middle of February 2010 with two brief interruptions in January for maintenance activities. On February 1 1th, sodium bromide injections were shut down in preparation for mid-cycle tunnel cleaning. Sodium hypochlorite injections continued for microfouling control. On February 18th sodium

hypochlorite injections were shut down for the tunnel cleaning. Simultaneous injections six times a day were restarted in late February and ran through the remainder of the quarter with three brief interruptions in March for maintenance activities.

Both Unit 2 conduits were treated with simultaneous injections of sodium bromide and sodium hypochlorite six times a day throughout the first quarter with three brief interruptions in January and two brief interruptions in March for maintenance activities.
