Monitoring of Plant Influent and Effluent.......................... 2 Monitoring of Receiving Waters....................................... 2 Sodium Bromide Treatment Program.............................. 2 APPENDIX 1: NP DES Discharge Points

OVERVIEW

1. During the 2nd Quarter of 2025, discharges occurred from Discharge Paths 001 (once-through cooling water), 0018, 0010, 001E, 001F, 001G, 001H, 001J, 001L, 001M, 001 N, 001 P, 002, 003, 004, and 005 through 015. No discharges occurred from Discharge Paths 0011, 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 Oiablo 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. During the 2nd Quarter of 2025, 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. On May 20, 2025, due to a biofouling clog in the seawater portion of the chemical injection system, a brief Total Residual Chlorine (TRC) spike occurred on the Unit-2 outfall monitors at the start of the routine 13:00 and 21 :00 chemical treatment cycles.

Discharge TRC concentrations were calculated at 101 ug/L (ppb) for the 5/20/25 13:00 injection cycle and 125 ppb for the 5/20/2521 :00 injection cycle. Upon further review of the redundant Unit 2 chlorine monitor strip charts, it was determined that an exceedance of the Ocean Plan calculated TRC discharge limit (89 ppb for 20-minute injections) did not occur due to a truncated chemical injection period. Close inspection of the redundant Unit 2 discharge monitor strip charts indicated the injection did not occur over a 20-minute period as programed. Chemical injections during this time, were estimated to be no greater than eight (8) minutes in duration. An 8 minute injection has a calculated Ocean Plan limit of 132 ppb. This is above the highest reading seen at the discharge. Therefore, no calculated Ocean Plan or instantaneous NPDES permit (200ppb) TRC limit exceedances occurred.

Monitoring of Plant Influent and Effluent

1. The results of the April, May, and June 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 May 23rd through May 27th, 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 TUa 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 May 23rd through May 25th, 2025, is attached to the CIWQS application submittal. The chronic bioassay results show that toxicity was 1.00 TUc (no chronic toxicity).

Monitoring Receiving Waters

1.

Ecological Studies at Diablo Canyon Ecological studies in the vicinity of Diablo Cove conducted during the 2nd 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.

C.

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 Unit-1 conduits were treated with simultaneous injections of sodium bromide and sodium hypochlorite six times per day throughout the second half of the 2nd Quarter.

Unit 1 conduit treatment was secured mid-April through late-May due to the 1 R25 refueling outage. Unit-1 conduit treatments were decreased to 10-minute injections in

late-May due to erratic fluctuations in TRO concentrations at the waterbox. Injections were secured in early June when the fluctuations were determined to be caused by biofouling in the Intake seawater supply lines and subsequent repairs were made. Brief chemical treatment interruptions also occurred twice in June for routine maintenance clearances and repairs.

Both Unit-2 conduits were treated with simultaneous injections of sodium bromide and sodium hypochlorite six times per day throughout most of the 2nd Quarter. Unit-2 conduit treatment was briefly secured at the beginning of the 2nd Quarter in early and late-April for repairs. Unit-2 conduit treatments were decreased to 10-minute injections in late-May due to erratic fluctuations in TRO concentrations at the waterbox. Injections were secured in early June when the fluctuations were determined to be caused by biofouling in the Intake seawater supply lines and subsequent repairs were made. Unit 2 conduits were secured briefly in mid-June for system repairs. Both Unit-2 conduits were subsequently treated with simultaneous injections for the remainder of the 2nd Quarter.
