Per Section 4.1 of the MRP, effluent samples shall be analyzed monthly for dissolved oxygen. An effluent sample for dissolved oxygen was inadvertently not collected in March due to a laboratory oversight. The Los Coyotes WRP was operating normally in March and effluent dissolved oxygen levels are expected to have been within normal ranges. To prevent this issue from re-occurring, staff have been instructed to more proactively monitor sample collection schedules to ensure that all required samples are collected. |

Per Section 5.1.16 of the WDR, the discharge shall not result in visible floating particulates, foams, or oil and grease in the receiving waters. On February 20 at 9:45 a.m., Sanitation Districts sampling personnel observed foam in the San Gabriel River downstream of Discharge Point 001B and traveling to receiving water station RSW-007 (R-13). Operations staff confirmed that the SJCE and SJCW WRPs were operating normally during this time and no changes to the treatment process or foaming had occurred at the plants. However, as a precautionary measure, the defoamant dose was increased at both WRPs the same day. The sampling crew returned to receiving water station RSW-007 (R-13) the following day on February 21 at 10:52 a.m. and observed less foam; by 2:14 p.m., the foam was no longer present. The Sanitation Districts will continue to monitor water quality in the effluent and receiving waters, and the San Jose Creek WRP Operations staff will continue their normal procedures to increase the defoamant dose if foam is observed. |

Radioactivity. Per the MRP, final effluent shall be analyzed quarterly for radioactivity. 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. |

Per Section 4.1 of the MRP, ammonia shall be analyzed weekly in the influent and effluent. No influent and effluent ammonia results are available for the week of December 8, 2024. Influent and effluent samples for ammonia analysis were collected on December 10, however, the samples were inadvertently lost after collection and could not be analyzed. Laboratory staff have reviewed sample handling and custody procedures to prevent reoccurrence of this issue. Make-up samples were collected on January 16, 2025, and the results will be included in the January 2025 monthly NPDES report. |

Per Section 4.1 of the MRP, effluent samples shall be analyzed monthly for aldrin and dieldrin. The effluent sample collected on November 28 was invalidated because it was not delivered to the laboratory within 72 hours for pH adjustment, as required by the analytical method for these compounds. Therefore, there are no reportable aldrin and dieldrin effluent results for the month of November. A make-up sample was collected on December 16 and will be included in the December monthly report. To prevent this issue from reoccurring, a 3-day sample hold time will be implemented to ensure that laboratory pH measurements and adjustments are completed within the 72-hour method requirement. |

Per Section 4.1 of the MRP, Oil and Grease shall be analyzed weekly in the effluent. An effluent sample was not analyzed the week of August 18, 2024. On August 19, a sample for oil and grease analysis was collected; however, an analyst did not follow proper extraction procedure and the sample was lost (the solvent gas valves in the extraction instrument were inadvertently not opened). To prevent the issue from reoccurring, analysts have been reminded to check the valves and verify solvent and gas levels prior to sample extraction. A make-up sample was collected on September 6, 2024, and will be included in the September NPDES report. |

Order Conditions |
An unauthorized discharge of recycled water occurred on September 29 at 9:40 a.m. in the City of Long Beach near the intersection of East Colorado St. and Orlena Ave. The leak occurred during construction of the City of Long Beach Public Works Colorado Lagoon Open Channel Project and was discovered by the project contractor, Reyes Construction. The source of the leak was a four (4) inch irrigation line serving Marina Vista Park. The isolation valve feeding the 4-inch line was closed at 11:30 a.m., successfully stopping the leak. On September 30 at 4:56 p.m., Long Beach Utilities confirmed that the irrigation line was recycled water. The volume of recycled water discharged was estimated to be 28,000 gallons. The discharge was contained within the construction site and discharged to Colorado Lagoon, which ultimately leads to the Pacific Ocean, through the on-site filtration system per the dewatering permit for the project. Per CWC Section 13529.2, recycled water spills reaching waters of the state of 50,000 gallons or more for water treated beyond Disinfected Secondary 2.2 standards are required to be reported to the Regional Board. Because the discharge did not exceed this threshold, immediate notification to the Regional Board was not required. On Monday September 30, the 4-inch recycled water line was further excavated, and it was discovered that the pipe had dislodged from the isolation valve at the gasket joint. The age of pipe materials and fittings are thought to be a factor in the cause of the leak. To prevent future leaks, the gasket joint and pipe were replaced on October 2 using glue-on PVC pipe and fittings. The discharge from this event consisted of fully tertiary treated recycled water, and any residual chlorine was expected to have dissipated during distribution, along the discharge route, or during dewatering. No impacts to public health or the environment are believed to have resulted from this incident. |

Per Section I of the MRP, recycled water shall be analyzed daily for settleable solids. The settleable solids result for the recycled water sample collected on September 26 was invalidated because the analyst did not read the result within the method's required analysis time. To prevent reoccurrence, Laboratory staff was reminded of the analysis requirement. Throughout the month, the Pomona WRP was operating under normal conditions and settleable solids results were all not detected (ND). Therefore, this result is expected to have been within normal range and to have been in compliance with the permit limits. |

Per Section I of the MRP, recycled water shall be analyzed daily for total coliform. The total coliform result for the recycled water sample collected on August 1 was invalid because the micro incubator fell out of temperature range during a planned electrical shutdown on August 2, preventing the analysis from being finalized. While the confirmation test for the sample analysis in process during that time is invalid, the presumptive result remains valid, although no confirmed results can be reported. The total coliform results were non-detectable (ND) in August, except on August 6 (2 CFU/100 mL) and 30 (1 CFU/100 mL). Therefore, this result is expected to have been within normal range and to have been in compliance with the permit limits. |

Per Section I of the MRP, recycled water shall be analyzed daily for total coliform. The total coliform result for the recycled water sample collected on July 30 was invalid because the micro incubator fell out of temperature range during a planned electrical shutdown on August 2, preventing the analysis from being finalized. While the confirmation test for the sample analysis in process during that time is invalid, the presumptive result remains valid, although no confirmed results can be reported. Throughout July, the coliform results ranged were all non-detectable (ND). Therefore, this result is expected to have been within normal range and to have been in compliance with the permit limits. |
