1091924 05/29/2021 Deficient Monitoring Results from a recycled water sample collected on May 29 were invalid because the 24-hour composite was comprised of less than 12 aliquots. This issue was caused by a laboratory staff error in running the autosampler equipment; staff were alerted to the error and have been reminded of proper procedures. Violation N eSMR Pomona Water Reclamation Plant 134831 81-034 N
1114555 01/03/2023 CAT1 Chloride Daily Maximum limit is 150 mg/L and reported value was 151 mg/L at EFF001 WRR. Violation N eSMR Pomona Water Reclamation Plant 134831 81-034 N
1148339 09/30/2024 CAT2 Aldrin Monthly Average limit is 0.012 lb/day and reported value was 0.02 lb/day at EFF-001. Violation N Report A.K. Warren Water Resource Facility 452398 R4-2023-0181 N
1097984 09/23/2021 CTOX Chronic Toxicity-C.dubia-Survival Monthly Median limit is 0 Pass/Fail (Pass = 0, Fail = 1) and reported value was 1 Pass/Fail (Pass = 0, Fail = 1) at EFF-001A. Violation N eSMR Los Coyotes WRP 385612 R4-2015-0124 N
1120972 07/24/2023 Deficient Monitoring Per Section 4 of the MRP, effluent samples shall be analyzed daily for Total Residual Chlorine. The Total Residual Chlorine result from the effluent sample collected on July 24 was invalid because the sample was not analyzed within the appropriate laboratory holding time. A make-up sample could not be collected due to lack of effluent flow after initial collection. Laboratory staff have reviewed procedures for tracking samples during handling and to complete analyses within the required holding time in the future. During this period, the Pomona WRP was operating under normal conditions; thus, this parameter is expected to be within normal range on this day. Violation N eSMR Pomona Water Reclamation Plant 432902 R4-2021-0097 N
1130537 05/01/2024 Deficient Monitoring 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. Violation N eSMR Whittier Narrows Water Reclamation Plant 443746 R4-2021-0096 N
1135640 09/26/2024 Deficient Monitoring 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. Violation N eSMR Pomona Water Reclamation Plant 134831 81-034 N
1106156 04/04/2022 Deficient Monitoring Per Section 8.1 of the MRP, receiving water samples shall be analyzed monthly for MBAS. Analytical results of samples collected from receiving water stations RSW-003 and RSW-006 on April 4 are invalid due to data integrity issues. Make-up samples will be collected as soon as possible. Corrective actions to prevent this from recurring include: 1) purchase and implementation of a spectrophotometer that has a reading log and can directly and electronically transfer results to the data management system to assure analytical results are accurately recorded, 2) routine review of analyst¿s adherence to laboratory Standard Operating Procedures (SOPs), and 3) additional staff assigned to oversee laboratory activities. Violation N eSMR Whittier Narrows Water Reclamation Plant 443746 R4-2021-0096 N
1103052 01/31/2022 CAT1 Ammonia, Total (as N) Monthly Average (Mean) limit is 4.1 mg/L and reported value was 4.79 mg/L at EFF-001A. Violation N eSMR Long Beach WRP 385694 R4-2015-0123 N
1085850 11/21/2020 Deficient Monitoring Per the MRP, recycled water samples shall be analyzed daily for total coliform. Results from the effluent sample collected on November 21 were invalid due to a leak of incubation bath water into the bag containing the sample. On November 21, the recycled water produced at the Long Beach WRP underwent adequate disinfection with normal chlorine dosing and flow; turbidity and other water quality parameters monitored in the plants final effluent were within permit limitations; and the plant was operating under normal conditions for the day. Thus, the coliform levels in the final effluent were likely below permit limitations on November 21. Violation N eSMR Long Beach WRP 133825 87-047 N

1096512 08/11/2021 Surface Water The receiving water sample collected at RSW-002 (R4) on August 11 exceeded the calculated 30-day average Basin Plan objective for ammonia. Because the compliance sample for effluent ammonia was collected earlier in the month, a concurrent effluent sample result for ammonia is not available. This incident was verified on Nov 5, and notification was provided to the Regional Board via telephone the same day at 1:58 p.m. Written confirmation was submitted on Nov 10. Although the receiving water sample exceeded the calculated 30-day average Basin Plan objective, the concentration observed was in compliance with the 4-day average Basin Plan objective for ammonia. Ammonia water quality objectives in the receiving water are calculated automatically in the Districts¿ Laboratory Management System so that an alert can be issued if objectives are exceeded. Due to a system error, Districts staff were not notified of this exceedance until the data was reviewed on Nov 5 during routine preparation of the monthly report. Upon confirmation of the exceedance, the Districts reviewed operational records and conditions at the Los Coyotes WRP at the time of the incident and have determined that all treatment processes were normal. On the day of the exceedance, the sampling crew observed that conditions were normal at RSW-002. Ammonia concentrations in the plants secondary treatment effluent on that day were within the typical range for plant operations, which indicates that the receiving water ammonia monitoring results for Aug 11 may have been anomalous and that the receiving water station may have been in compliance with the objective if more samples had been collected and analyzed. Lab staff have updated the computer application that calculates objectives and sends out ammonia exceedance alerts, and they have checked the system to make sure it is working properly. Lab staff also added a spreadsheet check to their data review to confirm and compare results manually. Violation N eSMR Los Coyotes WRP 385612 R4-2015-0124 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
1125030 01/04/2024 Deficient Monitoring Per Section I of the MRP, recycled water samples shall be analyzed daily for total coliform.

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.

1102078 12/30/2021 Deficient Reporting Per Section X.D.7 of the MRP, the discharger shall electronically submit a summary report of discharge to 003 and 004 outfalls within 5 days of completion of the discharge. Outfall 003 was opened on December 30 at 07:45 and closed on December 31 at 01:45 (18 hours) to provide hydraulic relief from high flows caused by a large storm event. During this storm, peak flows at JWPCP approached the hydraulic capacity of 675 million gallons per day (MGD), with a maximum flow of 539 MGD. Based on conditions at the time, including the tide height and the level of the water in the surge tower, Operations staff¿s best professional judgment was that temporary discharge of final effluent to Outfall 003 was necessary to avoid a potential plant overflow. The estimated flow rates to Outfall 003 while the gate valve was open on December 30 and 31 were approximately 51.7 MGD and 4.79 MGD, respectively, with a total volume of 35.4 million gallons. All required monitoring was conducted during the discharge event, and all results were within compliance limits. The discharge did not endanger human health or the environment. The opening of Outfall 003 was inadvertently overlooked in the daily summary email from Operations which resulted in the delayed response. To prevent this issue from re-occurring, Reuse and Compliance staff were reminded to review the daily email summaries each day to ensure that future outfall notifications will be made in a timely manner.

1086036 12/06/2020 Order Conditions An unauthorized discharge of Pomona WRP disinfected tertiary-treated recycled water occurred on December 6, 2020 from approximately 2:13 a.m. to 2:50 a.m. in Rowland Heights, CA near the intersection of Brea Canyon Cut Off Road and Balan Road. The Walnut Valley Water District (end user) reported the discharge to the Los Angeles County Sanitation Districts (Sanitation Districts) on December 16 at 10:54 a.m. The Sanitation Districts confirmed the discharge on December 17 at 11:10 am and provided verbal notification of the event to the Regional Board on the same day at 12:32 p.m. The unauthorized discharge occurred as a result of a car accident near the road intersection on December 6, 2020 at approximately 2:13 a.m. The accident sheared the roadside air vacuum valve and damaged the blow-off line. The estimated total discharge volume is approximately 180,000 gallons based on the size of the recycled water distribution line and duration of the discharge. To reach the nearest receiving water, the recycled water would have had to travel approximately 2.4 miles in the storm drain and discharge into the concrete-lined portion of the San Jose Creek. Residual chlorine in the recycled water would have decayed before reaching the receiving water due to the 2.4-mile travel distance and contact with substances exerting chlorine demand along the storm drain. As a verification measure, staff from the Sanitation Districts' Biological Sciences Group inspected San Jose Creek near the discharge point in Rowland Heights at 1:55 p.m. on December 17. There were no negative biological impacts observed. Because the unauthorized discharge was caused by an unforeseen car accident, additional preventative measures cannot be implemented to prevent a reoccurrence. Walnut Valley staff and Sanitation Districts' staff will review the notification and reporting procedures for unauthorized discharges. Violation N eSMR Pomona Water Reclamation Plant 134831 81-034 N

1143312 02/20/2025 Surface Water 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.

1127581 02/04/2024 Order Conditions Turbidity and settleable solids levels were elevated as a result of the partial tertiary filter bypass events that occurred at the San Jose Creek WRPs on February 4-5, 2024, due to an exceptionally heavy rainfall. The turbidity value was 9 NTU at EFF-001 and 8.3 NTU at EFF-002 in the 24-hour composite samples on February 5. Turbidity values at EFF-002 exceeded 5 NTU for a total of 920 minutes and exceeded 10 NTU for a total of 885 minutes. Settleable solids exceeded the maximum daily effluent limitation at EFF-002 with a value of 0.4 mL/L. Laboratory staff found no adverse biological effects during field observations. Under 40 CFR § 122.41(m)(1), (3), and (4), the bypass events were not prohibited because they were unavoidable to prevent severe property damage, there were no feasible alternatives, and notice was submitted to the Regional Board in accordance with permit requirements. This event was a single operational upset that was caused by the exceptional rainfall, not by wastewater treatment operator error or negligence; exceedances would not have occurred if not for the upset of the secondary biological treatment process; the Sanitation Districts carried out all reasonable and immediately feasible actions to reduce noncompliance with the applicable effluent limitations; and the Sanitation Districts maintain an approved pretreatment program.

The Ceriodaphnia dubia chronic toxicity test initiated for receiving water station RSW-002 on October 11 failed the Test of Significant Toxicity (TST) with a 30.3% reproduction effect and 60.0% survival effect in undiluted receiving water. Dr. Jeong-Hee Lim, Chief of the Watershed Regulatory Section, was immediately notified via voicemail at 4:44 p.m. on October 18, followed by written notification on October 23. High total chlorine residual from Long Beach WRP was initially reported as a potential source of the receiving water toxicity. Upon further review of the Long Beach WRP final effluent chlorine residual monitoring data from October 13, the source of the receiving water toxicity is unknown . Biological observations were conducted immediately, noting the presence of fish and birds, with no negative impacts observed.

On January 3 at approximately 5:47 a.m., the residual chlorine meter in the final effluent exceeded 0.5 mg/L for over five minutes. Operations staff identified the cause as a blockage in the feed line for the sodium bisulfite dechlorinating agent and restored the bisulfite flow at approximately 6:30 a.m. Plant operators collected a grab sample from the final effluent at 7:38 a.m. following the incident and sent it to the laboratory for analysis. Laboratory staff analyzed the chlorine residual concentration in the sample and noted the concentration was non-detect. However, because the laboratory staff erroneously believed the sample was only being used for operational control, they did not record the sample result using their standard protocols. Thus, there is no official documentation of the sample collected January 3 at 7:38 a.m. following the chlorine residual exceedance.

1117819 04/05/2023 Deficient Monitoring Per Section I of the MRP, recycled water samples shall be analyzed daily for total coliform. The total coliform result in the recycled water sample collected on April 5 was invalidated because the test initiation time was not properly recorded. All other coliform results for the month were either non-detect or 1 CFU/100 mL, therefore, this result was expected to be within normal ranges. Laboratory staff were reminded of proper recording and review procedures. Violation N eSMR Pomona Water Reclamation Plant 134831 81-034 N

1125029 01/08/2024 Order Conditions An unauthorized recycled water discharge of a maximum of 9,000 gallons occurred on January 8 from roughly 7:10 a.m. to 7:30 a.m. at the Sanitation Districts' Spadra Landfill located at 4125 West Valley Boulevard in the city of Walnut. The Sanitation Districts notified the Regional Board at 3:45 p.m. on January 8, with a follow up letter on January 12. The unauthorized discharge originated from a below-grade recycled water distribution line near Bench 5 of the landfill on the southwestern side of the facility. The discharge occurred due to a crack in a Victaulic pipe connection fitting which allowed the line to separate, discharging recycled water into the soil. The pipe separation led to surface runoff downslope and into the storm drain prior to the pipeline being isolated. The leak was observed at approximately 7:10 a.m. on January 8, and continued until approximately 7:30 a.m. the same day, when site staff isolated the line. Recycled water was discharged into the soil until it became saturated, emanated from the surface and began to flow approximately 400 feet down the bench road before entering a catch basin. The discharge then flowed another approximately 600 feet before entering a Los Angeles County Department of Public Works storm drain. This storm drain ultimately discharges into the San Jose Creek. The recycled water produced at the Pomona WRP is suitable for discharge to the San Jose Creek per its National Pollutant Discharge Elimination System permit (Order No. R4-2021-0097), therefore no impacts to public health or the environment are expected. Staff reported that there was little flow in the San Jose Creek channel and there were no indications that fish or wildlife had been adversely impacted; therefore, there were no observed biological impacts from the discharge. To minimize reoccurrence of similar events, the Sanitation Districts will investigate the installation of above-grade recycled water lines and initiate a Victaulic fitting inspection program.

1109187 08/13/2022 Deficient Monitoring Per Section I of the MRP, recycled water shall be analyzed daily for total coliform. Total coliform results from recycled water samples collected on August 13 and 14 were invalid because expired media was inadvertently used during laboratory analysis. To prevent this issue from re-occurring, laboratory staff will ensure that the correct media is used for total coliform analyses. The Pomona WRP was operating under normal conditions during the month. Thus, total coliform concentrations in the final effluent are expected to have been within normal ranges.

1122428 10/11/2023 Deficient Monitoring Per Section I of the MRP, recycled water samples shall be analyzed daily for total coliform. The total coliform result in the recycled water sample collected on October 11 was invalidated because of improper sample incubation procedure. The analyst failed to write down the read time on the lab bench sheet and was unable to verify the correct duration of the incubation period. Throughout the month, the coliform results were typically non-detectable, except for five separate instances in which it was recorded at 1 CFU/100mL. Therefore, this result was expected to be within normal range and in compliance with the WRRs. To prevent a recurrence of this issue, Laboratory staff will double check that the sample data is properly filled out on the bench sheet.

1135651 09/29/2024 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. Violation N eSMR Long Beach WRP 133825 87-047 N
