1143987 03/31/2025 Deficient Monitoring For the receiving water requirements there was one deficient monitoring violation for station RSW-LAGT654(a) for the January through March period. The quarterly oil and grease monitoring for this station was not conducted due to an analyst error, this resulted in one monitoring deficiency. Violation N eSMR Los Angeles-Glendale WWRP 452152 R4-2022-0343 N
1144711 04/22/2025 Deficient Monitoring The influent flow meter was calibrated on April 21, 2025. There was, however, an issue with the influent flow meter, which was addressed on May 7, 2025. Because of the issues with the flow meter, the influent and calculated effluent monthly average and daily maximum flows from 4/22/25 - 5/8/25 are inaccurate and, therefore, not reportable, resulting in a deficiency in monitoring for April 2025. Violation N eSMR Terminal Island Water Reclamation Plant 443776 R4-2021-0095 N
1146051 05/01/2025 Deficient Monitoring The influent flow meter was calibrated on April 21, 2025. There was, however, an issue with the influent flow meter, which was addressed on May 7, 2025. Because of the issues with the flow meter, the influent and calculated effluent monthly average and daily maximum flows from 4/22/25 - 5/8/25 are inaccurate and, therefore, not reportable. Also, because the daily flow is used to calculate maximum daily load, constituents sampled within the dates of inaccurate flow cannot be calculated for maximum daily load (other loading results calculated by monthly average flow were unaffected). This resulted in one deficiency in monitoring for May 2025. Violation N eSMR Terminal Island Water Reclamation Plant 443776 R4-2021-0095 N
1146436 11/30/2024 CAT1 Settleable Solids Monthly Average limit is 0.1 ml/L and reported value was 0.6 ml/L at M-008. Violation N Report Big Rock Mesa Drainage Facility 193437 R4-2018-0125 N
1149316 08/23/2025 Deficient Monitoring There was one monitoring deficiency for the HWRP weekly permit requirements.

To avoid this issue in the future, the staff was retrained on proper preservation procedures for the analytical method. 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.
