1148189 07/27/2025 Deficient Monitoring On August 2, 2025, the analytical batch containing EFF-001, INF-001, INF-002, INF-003, INF-004, and INF-005, all collected on July 27, 2025, failed QC requirements for biochemical oxygen demand (BOD). The failure was due to a dissolved oxygen depletion below 1 mg/L after five days. Violation N eSMR Hyperion WWTP 447793 R4-2023-0033 N
1148226 07/24/2025 Deficient Monitoring Maintenance was being conducted on the associated devices that record the flow data for the DCTWRP influent on July 24, 2025. Due to that, the influent flow data that was recorded was not accurate. The influent flow is a continuous monitoring requirement reported on a daily basis for the daily average flow and daily maximum flow. The total daily flow for the influent on July 24, 2025 will be reported as an instrument failure (IF). This resulted in one deficient monitoring violation for July 2025. Violation N eSMR Donald C. Tillman WWRP 447892 R4-2022-0341 N
1148311 07/29/2025 Deficient Monitoring Per Sections 3.1 and 4.1 of the MRP, influent and effluent samples shall be analyzed weekly for biochemical oxygen demand (BOD, 5-day at 20° Celsius). The influent and effluent samples collected on July 29 were invalidated due to a laboratory analyst error affecting the analytical QA/QC samples. Therefore, there are no BOD results for influent and effluent the week of July 29. Make-up samples were collected on August 6 and will be reported in the August monthly NPDES monitoring report. To prevent this issue from reoccurring, laboratory staff were reminded to review and follow all method standard operating procedures (SOPs).

1149348 08/05/2025 Deficient Monitoring Per Section 8.1 of the MRP, receiving water samples from receiving water monitoring stations RSW-001U (R-C), RSW-002D (R-D), and RSW-003D (R-E) shall be analyzed monthly for settleable solids. On August 5, receiving water samples were collected from each monitoring station and successfully analyzed for settleable solids; however, the settleable solids results were not saved during data entry into the laboratory information management system (LIMS). Because settleable solid results are entered directly into LIMS, there is no physical record of the August 5 results. Make-up samples were collected on September 18, and the results will be included in the September NPDES compliance monitoring report. To prevent reoccurrence of this issue, laboratory analysts have been reminded to ensure all data entries are properly saved in LIMS. Violation N eSMR Valencia WRP 435564 R4-2022-0174 N

1150397 10/03/2025 Deficient Monitoring There was one monitoring deficiency for the HWRP daily permit requirements. EFF-001, INF-001, INF-002, INF-003, INF-004, and INF-005 collected on October 3, 2025 failed QC requirements for biochemical oxygen demand (BOD). The failure was due to dissolved oxygen depletion to below 1 mg/L, resulting in a result of AE for all six samples. The failure was attributed to contamination in the reagent water, likely due to new tubing that was not decontaminated prior to use. Violation N eSMR Hyperion WWTP 447793 R4-2023-0033 N

1150884 11/04/2025 Deficient Monitoring Semi-annual Bacteria Grab (Total Coliform, Fecal Coliform and Enterococcus) The Scattergood Generation Station (SGS) NPDES Permit No. CA0000370 requires the Outfall Effluent (EFF-001) to be sampled for Total Coliform, Fecal Coliform and Enterococcus Bacteria on a semi-annual basis for 5 consecutive weeks. The sampling for Weeks 1 through Week 4 took place during October 2025. During the month of November 2025, there was insufficient flow for the 5th week of bacteria grab sampling. The sampling for Week 5 took place on 12/2/2025. All lab results from the Semi-annual Bacteria Grab samples remained below the 30-day geometric mean limits, and below the single sample maximum limits.

1154399 02/28/2026 Surface Water Per Section 5.1.20 of the NPDES permit, waste discharge shall not cause the ammonia water quality objectives in the Los Angeles Region Basin Plan (Basin Plan) to be exceeded in receiving waters. On February 23, the measured ammonia concentration at receiving water station RSW-002, which is located downstream of the Long Beach WRP discharge point, was 8.31 mg/L (as nitrogen), which exceeded the calculated chronic (30-day average) Basin Plan objective of 5.3 mg/L based on concurrent pH and temperature measurements. The ammonia concentration met the calculated acute (1-hour average) objective of 23 mg/L. Final effluent ammonia monitoring at the Long Beach WRP was conducted on February 3 and 10, with results of 4.66 and 3.16 mg/L (as nitrogen), respectively. Final effluent ammonia was not measured on February 23, 2026. The Long Beach WRP was operating under normal conditions at the time of the exceedance, and no significant operational issues or process upsets were identified that would indicate reduced ammonia removal or treatment performance at the plant. Accordingly, no direct cause could be determined for the elevated ammonia concentration at the downstream receiving water station. Violation N eSMR Long Beach WRP 447474 R4-2022-0032 N

1155408 03/31/2026 Surface Water Per Section 5.1.21 of the WDR, there shall be no chronic toxicity in ambient waters as a result of wastes discharged. Per Section 8.1 of the MRP, compliance with this objective is determined using the monthly median chronic toxicity summary result. In March 2026, the monthly median chronic toxicity summary result at receiving water monitoring station RSW-007 (R-13) exceeded the narrative receiving water objective. The monthly median result was based on two valid Ceriodaphnia dubia chronic toxicity tests conducted by the Sanitation Districts' San Jose Creek Water Quality Laboratory. A toxicity test initiated on March 17 using receiving water grab samples collected on March 16, 18, and 20, failed the Test of Significant Toxicity (TST) with a 46.9% reproduction effect and a 15.0% survival effect in the undiluted receiving water sample. A test initiated on March 26 using grab samples collected on March 25, 27, and 30, also failed the TST with a 34.4% reproduction effect and a 0% survival effect in the undiluted receiving water sample. Because two valid tests conducted during March 2026 failed the TST, the monthly median toxicity summary result at RSW-007 (R-13) also failed the TST and therefore exceeded the narrative receiving water chronic toxicity objective. In accordance with Sections 6.1.2.y and 5.5.1 of the NPDES permit, the Regional Board was notified by telephone on April 2 at 8:26 a.m., and written notification was provided on April 6. No obvious causes for the observed toxicity were identified. Final effluent from the SJCE and SJCW WRPs met the chronic toxicity maximum daily and monthly median effluent limits in March 2026. The Sanitation Districts will continue to monitor receiving water toxicity and will conduct further investigation if persistent toxicity is observed.

1154398 02/28/2026 Surface Water Per Section 5.1.21 of the NPDES Permit, waste discharge shall not cause the ammonia water quality objective in the Los Angeles Region Basin Plan (Basin Plan) to be exceeded in the receiving waters. Per Section 8.2 of the MRP, compliance with the ammonia water quality objective for the Los Coyotes WRP is assessed at receiving water station RSW-002 (R-4), which is located downstream of the Los Coyotes WRP discharge point. The measured ammonia concentration in the receiving water at RSW-002 (R-4) on February 23 was 5.96 mg/L (as nitrogen), which exceeded the calculated chronic (30-day average) Basin Plan objective of 4.3 mg/L using the concurrent pH and temperature monitoring results at RSW-002 on the same date. The ammonia concentration at RSW-002 met the calculated acute (1-hour average) objective of 14 mg/L. Final effluent ammonia monitoring at the Los Coyotes WRP was conducted earlier in the month on February 4 (with a result of 1.7 mg/L ammonia as nitrogen). Therefore, a final effluent ammonia concentration is not available on February 23. The Los Coyotes WRP was operating under normal conditions at the time of the exceedance, and no operational issues or process upsets were identified that would indicate reduced ammonia removal or treatment performance at the plant. Accordingly, no direct cause could be determined for the elevated ammonia concentration at the downstream receiving water station. Violation N eSMR Los Coyotes WRP 445113 R4-2021-0142 N
