OVERVIEW

1. During the 1st Quarter of 2025, discharges occurred from Discharge Paths 001 (once-through cooling water), 001 B, 001 D, 001 E, 001 F, 001 G, 001 H, 001 L, 001M, 001N, 001P, 002, 003, 004, and 005 through 015. No discharges occurred from Discharge Paths 0011, 001J, 001 K, 016 and 017. A list of all permit discharge pathways, including name and number, is provided in Appendix 1.

2. The substances listed in Table B of the California Ocean Plan were each analyzed for and reported in the permit renewal application and application updates for Diablo Canyon Power Plant (DCPP) submitted in 1994, 2001, and 2011. There have been no changes in activities conducted at the plant that would have significantly affected the results previously reported in the above referenced documents. Ocean Plan Table B substances not analyzed for this quarter were not added to any plant discharge streams.

3. Redundant total residual chlorine monitors were installed at Discharge 001 and began operation in December 2024, resulting in elimination of affected discharge data requiring engineering evaluation in the 1st Quarter 2025. No events affected the results of continuous chlorine monitoring at Discharge 001 during the 1st Quarter 2025.

4. Errata: During review of 2024 data, errors in daily chlorine usage data were discovered for the months of January and February. These errors had a minimal impact on monthly chlorine usage reported in the 102024 and 2024 annual reports. Following corrections to the data reported in the 102024 Attachment 1, revised monthly chlorine usage for January increased from 10,683 lbs to 10,817 lbs, and February decreased from 12,148 lbs to 12, 143 lbs. January monthly average chlorine use also increased from 345 lbs/day to 349 lbs/day. Minimum chlorine use reported for February in the 2024 annual report increased from 283 lbs/day to 403 lbs/day.

SUMMARY

OF MONITORING PROGRAM A.

Monitoring of Plant Influent and Effluent

1. The results of the January, February, and March 2025 plant influent and effluent monitoring have been reported via the CIWQS web application to which this letter is attached.

2. The laboratory report for one acute bioassay on water sampled from Discharge 001,

performed January 17th through January 21 st, 2025, is attached to the CIWQS application submittal. The acute bioassay results show that toxicity was 0.0 TUa (no acute toxicity).

Note: The 0. 0 TU a value is not included in the CIWQS application spreadsheet as the formatting of the data spreadsheet does not accommodate zero value entries.

3. The laboratory report for one chronic bioassay on water sampled from Discharge 001, performed March 19th, 2025, is attached to the CIWQS application submittal.

The chronic bioassay results show that toxicity was 1.00 TUc (no chronic toxicity).

As in previous quarters, DCPP was unable to complete the chronic toxicity test using red abalone for the 1st Quarter 2025 report. The contract laboratory was unable to complete the test due to elevated ocean temperatures, which prevented abalone spawning needed for the test. As allowed under Order 90-09, NPDES No. CA0003751 and previous written agreement with the CCRWQCB, purple urchin was used for the 1st quarter chronic toxicity test in lieu of red abalone.

Monitoring of Receiving Waters

1.

Ecological Studies at Diablo Canyon Ecological studies in the vicinity of Diablo Cove conducted during the 1st 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 Moss Landing Marine Laboratories MLML (administered by San Jose State University) in their periodic report for this program.

Sodium Bromide Treatment Program Diablo Canyon Power Plant is continuing the use of 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 chemical injection treatment attempts to achieve a target concentration in the range of 250-300 parts per billion (ppb) Total Residual Oxidant (TRO) when measured at the inlet waterbox of the condenser. Discharge TRO concentrations measured at the plant outfall remained below NPDES permit limitations and the calculated Ocean Plan limit throughout the quarter.

Both conduits of Unit-1 were treated with simultaneous injections of sodium bromide and sodium hypochlorite six times per day throughout the 1st Quarter. There were brief interruptions in Unit-1 treatments in late-January and late-March due to scheduled injection equipment maintenance and equipment clearances. Bromine injections were secured for several days in late January due to intake bulk chemical storage low product volume.

Both conduits of Unit-2 were treated with simultaneous injections of sodium bromide and sodium hypochlorite six times per day throughout most of the 1st Quarter. There were brief interruptions in Unit-2 treatments in early-January due to a dechlorination system line blockage and in late-January due to scheduled injection equipment maintenance and equipment clearances. Bromine injections were secured for several days in late January due to intake bulk chemical storage low product volume. Unit 2 chemical treatment injections were also secured during the second work-week of mid-March to support a scheduled mid-cycle seawater conduit cleaning curtailment.
