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

At the Pomona WRP, the second quarter grab samples for gross alpha, gross beta, uranium, radium-226, radium-228, tritium, and strontium-90 were not collected due to a Laboratory oversight. Following the Laboratory Information Management System (LIMS) update in November 2024, the Sanitation Districts identified a system issue in which the automated regeneration of sampling events for certain compounds began defaulting to an incorrect interval rather than the intended frequency. The Sanitation Districts¿ LIMS administrator is aware of the issue and is actively working with the system¿s provider to resolve it. As a corrective measure, a separate schedule has been established to ensure these compounds continue to be sampled on a quarterly basis. Make-up samples were collected on April 8, and the results will be reported in the April 2025 monthly compliance report. The Pomona WRP was operating under normal conditions during the month. Thus, the concentrations of the radioactivity compounds in the final effluent are expected to have been within normal ranges. Violation N eSMR Pomona Water Reclamation Plant 134831 81-034 N

1143334 02/19/2025 Deficient Monitoring Per Section 4.1 of the MRP, continuous monitoring of total residual chlorine shall serve as a trigger for increased grab sampling for total residual chlorine excursions of up to 0.3 mg/L lasting more than 15 minutes or excursions between 0.1 to 0.3 mg/L lasting longer than 15 minutes. At 11:50 a.m. on February 19, the Valencia WRP temporarily lost power while testing the emergency generators. The emergency generators turned on; however, there was a slight delay, resulting in temporary power loss at the Valencia WRP. As a result, the UV disinfection system was shut down, and all effluent flow was routed to the chlorine contact tanks for disinfection. During this transition, the metered final effluent total residual chlorine exceeded 0.3 mg/L for approximately 8 minutes and remained between 0.1 and 0.3 mg/L for approximately 16 minutes, triggering collection of an additional grab sample. At 12:25 p.m., a grab sample was collected, and chlorine was not detected; however, collection and analysis did not follow analytical method protocols. As a result, the non-detect result was not reportable. Despite this, sodium bisulfite, the dechlorination chemical, was dosed more than the stoichiometric amount needed to fully dechlorinate the effluent; therefore, the effluent was fully dechlorinated. To prevent reoccurrence, the Sanitation District will implement procedures to ensure all additional grab samples collected for total residual chlorine analysis follow analytical method protocols.

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
