Deficient Monitoring |
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. |

Deficient Monitoring |
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. |

Per Section 4.1 of the MRP, effluent samples shall be analyzed weekly for total suspended solids (TSS). An effluent TSS sample was inadvertently not collected or analyzed during the week of April 28. A make-up sample was collected in August and the result will be included in that monthly report. Per Section 8.1 of the MRP, receiving water samples shall be analyzed monthly for Methylene Blue Active Substances (MBAS). A sample collected on May 1 from receiving water station RSW-001 (R-11) was invalid because the method's hold time was exceeded by the contract lab. A make-up sample was collected in July and the result will be included in that monthly report. |

Per Section 5.1.3 of the WDR, the dissolved oxygen (DO) in the receiving water shall not be depressed below 5 mg/L as a result of the wastes discharged. On May 2 at 9:04 a.m., DO was 0.2 mg/L in a grab sample collected at receiving water station RSW-002. A 24-hour notification of the exceedance was provided via telephone to Dr. Jeong-Hee Lim on May 3 at 3:10 p.m. and a 5-day letter was submitted on May 8. This incident was investigated further, and additional details were provided in a 30-day letter submitted on June 7.  The Sanitation Districts implemented the following corrective actions: 1.Manual Mode: The SBS system will not be placed into manual mode unless staff is present onsite to monitor and respond to changing effluent flow conditions. Beginning May 8, the WRP was temporarily staffed continuously until the Secondary System SBS Dosing Pumps were fully operational on June 3 2.Installation of SBS Dosing Pumps at Secondary SBS Station: At the time of the incident, WRP staff was in the process of installing two peristaltic pumps to the Secondary (Emergency) SBS station (located adjacent to the forebay) and new SBS pipelines to transfer SBS from the existing 10,000-gallon storage tank to the Secondary SBS station and eliminate the need for carrier water. The transfer pump is used to fill the secondary tank as needed from the Primary Sodium Bisulfite Station. This dosing method has recently been employed at other WRPs and successfully eliminated the kind of plugging experienced at the WRP. As a result of the incident, staff accelerated construction and completed installation and programming required for the new peristaltic pumps and transfer line on June 3, and is using the new dosing system. 3.Eliminate Flow between Forebay Weir and Wall: The flow between the forebay weir and concrete walls was eliminated by plugging/caulking along the edges. The edges of the metal weir in the forebay were sealed on May 16. |

Per Section 4.1 of the MRP, total coliform and enterococcus shall be analyzed daily in the effluent at the manifold stations (EFF-002A and EFF-002B). There are no reportable results for enterococcus and total coliform at the manifold stations on May 9. Samples were inadvertently incubated at incorrect temperatures due to misinterpretation of container labels. To prevent a reoccurrence of this issue, analysts have been reminded to carefully verify labels prior to incubation. In addition, an end-of-day verification protocol has been implemented to promptly identify and correct any issues. |

Per the MRP, effluent shall be monitored daily for total coliform. On May 9, the total coliform result was invalidated due to a laboratory error in which the analyst misread the setup time and read the results 30 minutes before 22-24 hour read time. To prevent reoccurrence, Laboratory staff will ask questions if unsure about handwriting and take more time to read the setup time. Pomona WRP was operating under normal conditions during the month. Thus, the total coliform concentration in the effluent on this day is expected to have been within normal range and in compliance with effluent limitations. |

Per Section 4 of the MRP, effluent samples shall be analyzed quarterly for oil and grease. The quarterly effluent grab sample for oil and grease was inadvertently not analyzed due to laboratory oversight. The next quarterly oil and grease monitoring is scheduled for June and the result will be reported in the appropriate monthly monitoring report. To prevent a recurrence of this issue, laboratory staff have reviewed and revised procedures for tracking samples. During this period, the Pomona WRP was operating under normal conditions; thus, this parameter is expected to be within normal range on this day. |
