Violation N eSMR Los Angeles-Glendale WWRP 452152 R4-2022-0343 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.

Hollywood Way and Thornton Ave. to Drainage Conveyance System Violation null SSO Burbank City, Public Works CS 300767 2022-0103-DWQ N 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 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.

No reportable 24-hour composite turbidity result is available for the week of October 19 because the composite effluent sample collected for turbidity analysis on October 21 was not analyzed within the method holding time. A makeup composite sample was collected on November 5 and will be reported in the November 2025 NPDES monthly monitoring report. The turbidity result from the effluent grab sample collected the week of October 19 was within normal ranges. To prevent reoccurrence of this issue, the laboratory has implemented an automated alert in the Laboratory Information Management System (LIMS) to notify staff when turbidity samples have been collected and are ready for analysis.
