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.

1097977 09/30/2021 Deficient Monitoring For the sediment requirements there were deficient monitoring violations for stations RSW-4(4), RSW-W2(W-2), and RSW-LATT622(D). There are no results to report for the diazinon quarterly requirements for the July through September 2021 period and the pesticides semiannual requirements for the July through December 2021 period. The analysis for these constituents are contracted out. During this period, the contract lab that normally conducts this analysis was relocating so they decided to subcontract the analysis. Due to this, the samples were analyzed after their holding time so results are not reportable. The permit specifies that quarterly and semiannual requirements must be conducted in the third quarter, so by the time this issue was noticed it was already past the third quarter and resampling was not possible. This resulted in 3 monitoring deficiencies for the quarterly requirements. Violation N eSMR Donald C. Tillman WWRP 412169 R4-2017-0062 N

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).

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.

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. Violation N eSMR Pomona Water Reclamation Plant 134831 81-034 N

1103993 02/08/2022 Deficient Monitoring A review of effluent TSS data on February 14, 2022, discovered a high result of 71 mg/L on the February 8 sample, outside the normal range of recent results. Typically, the ratio of biological oxygen demand (BOD) and TSS are near 1:1, but the ratio for that day was 2.7:1. Other effluent parameters, such as BOD (26 mg/L), turbidity (13 NTU), and settleable solids (<0.1 mL) were within the expected range. A reanalysis of the sample that was conducted one day past the acceptable holding time yielded a result of 22 mg/L, within the expected range. The original TSS result has been determined to be invalid. The reanalysis, while it produced the expected result, is also invalid as it was past the holding time of the sample. TSS monitoring in Hyperion effluent is required daily and there is no valid result to report for February 8. Violation N eSMR Hyperion WWTP 384601 R4-2017-0045 N

1109951 08/13/2022 Deficient Monitoring For the weekly lake requirements there were deficient monitoring violations for stations RSW-4(4) and RSW-W2(W-2). The sample for both RSW-4(4) and RSW-W2(W-2) on August 12 were not analyzed for total phosphorous, organic phosphorous, and condensed phosphorous within their holding time. On Thursday August 4 the boat used to collect samples broke its motor and propeller while attempting to collect sediment samples. The following week, the boat was still not repaired and the Department of Parks and Recreation staff collected the water quality sample on August 9 from the shoreline which was believed to be an alternate site. Correspondence was sent to the LA-RWQCB on August 9 notifying them that this location was used. The Regional Board replied on August 11 that the alternative site used in the past needs prior approval, so that sample was deemed not representative. Finally, the boat was repaired on Thursday August 11 and a sample was collected mid-lake at the permitted location on August 12. The laboratory had to scramble to conduct analysis for the compounds that have short holding times, such as the nutrients (nitrogen series and phosphorus series). Due to staff shortages, an analyst was pulled from another laboratory to conduct phosphate analysis. This analyst was under the impression that he was only coming in on Saturday to perform ortho-phosphorus on overtime. The analysis for total phosphorous, organic phosphorous, and condensed phosphorous were not analyzed that day and only discovered when the sample was past holding time. The root cause of this missed analysis is a lack of communication combined with staff shortages. This event also happened when the supervisor of the analysis lab was on vacation. This resulted in a deficient monitoring violation for stations RSW-4(4) and RSW-W2(W-2). Violation N eSMR Donald C. Tillman WWRP 412169 R4-2017-0062 N

1113286 11/01/2022 Deficient Monitoring Per Section 4.1 of the MRP, continuous monitoring of total chlorine residual shall serve as a trigger for increased grab sampling for total chlorine residual excursions of up to 0.3 mg/L lasting more than 15 minutes. On November 1, the UV system was shutdown and all effluent flow was routed to the chlorine contact tanks (CCTs) for disinfection. During the transition, the metered final effluent total chlorine residual was between 0.1 and 0.3 mg/L for approximately 21 minutes which triggered grab sampling. A sample was collected; however, analysis of the grab sample did not follow analytical method protocol and, 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.

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

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.&#8195; 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.

1097976 09/30/2021 Deficient Monitoring For the sediment requirements there were deficient monitoring violations for stations RSW-4(4), RSW-W2(W-2), and RSW-LATT622(D). There are no results to report for the diazinon quarterly requirements for the July through September 2021 period and the pesticides semiannual requirements for the July through December 2021 period. The analysis for these constituents are contracted out. During this period, the contract lab that normally conducts this analysis was relocating so they decided to subcontract the analysis. Due to this, the samples were analyzed after their holding time so results are not reportable. The permit specifies that quarterly and semiannual requirements must be conducted in the third quarter, so by the time this issue was noticed it was already past the third quarter and resampling was not possible. This resulted in 3 monitoring deficiencies for the quarterly requirements. Violation N eSMR Donald C. Tillman WWRP 412169 R4-2017-0062 N

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.

1109205 07/07/2022 Deficient Monitoring Per Section 8.1 of the MRP, receiving water samples shall be analyzed monthly for nitrate, nitrite, nitrate plus nitrite, and total nitrogen. Nitrate, nitrite, nitrate plus nitrite, and total nitrogen results from a receiving water sample collected at RSW-001D (R-A) on July 7 were invalid because the sample was not analyzed within the appropriate laboratory holding time. The sample collected from RSW-001D was inadvertently switched with another sample prior to analysis, and by the time laboratory staff noticed the error, the RSW-001D sample was outside of the holding time and therefore not analyzed. A make-up sample was collected on September 7 and the results will be included in the corresponding report. Laboratory staff have reviewed procedures for tracking samples during handling and to complete analyses within the required holding time in the future.

1097975 09/30/2021 Deficient Monitoring For the sediment requirements there were deficient monitoring violations for stations RSW-4(4), RSW-W2(W-2), and RSW-LATT622(D). There are no results to report for the diazinon quarterly requirements for the July through September 2021 period and the pesticides semiannual requirements for the July through December 2021 period. The analysis for these constituents are contracted out. During this period, the contract lab that normally conducts this analysis was relocating so they decided to subcontract the analysis. Due to this, the samples were analyzed after their holding time so results are not reportable. The permit specifies that quarterly and semiannual requirements must be conducted in the third quarter, so by the time this issue was noticed it was already past the third quarter and resampling was not possible. This resulted in 3 monitoring deficiencies for the quarterly requirements. Violation N eSMR Donald C. Tillman WWRP 412169 R4-2017-0062 N

1125033 12/22/2023 Order Conditions Per Section 3.1 of the WDR, discharge of treated wastewater at a location different from that described in the Order is prohibited. On Dec 22, 2023, at approx. 11:48 AM, a chlorinated secondary effluent spill occurred at the Warren Facility due to a broken wash water line. Chlorinated secondary effluent flowed from the Warren Facility into an LA County flood control storm drain catch basin. The spill then flowed into the Wilmington Drain which discharges into Machado Lake. Sandbag containment was deployed at approx. 1:06 PM to completely stop the spill from entering the storm drain. The total amount of chlorinated secondary effluent that entered the storm drain is approx. 18600 gal. Per Section 7.1.2.y of the WDR, if a discharger does not comply or will be unable to comply for any reason, with any prohibition of this Order that may endanger health or the environment, the Discharger shall notify the Manager of the Watershed Regulatory Section at the Los Angeles Regional Board (RB) by telephone, within 24 hours of having knowledge of such noncompliance and shall confirm this notification in writing within 5 days, unless the RB waives confirmation. RB staff was notified of the exceedance on Dec 22, 2023, at 2:30 PM, within 24-hours of receiving the preliminary notification. An email confirmation was sent to the RB on Dec 27, 2023, within 5 days of receiving the spill notification. No impacts to human health, the environment, or beneficial uses of surface water are anticipated from the incident. The discharge consisted of disinfected secondary effluent, and residual chlorine was expected to have been reduced or otherwise dissipated in the storm drain before reaching Wilmington Drain over 3,600 feet away, or Machado Lake at almost 5,000 feet. No negative impacts were observed during biological observations taken on Dec 22, 2023. Warren Facility maintenance staff replaced the corroded pipe and a project has been initiated to replace and relocate the wash water line. Violation N eSMR A.K.

1124195 11/22/2023 Order Conditions Per Section 3.1 of the permit, discharge of treated wastewater at a location different from that described in the Order is prohibited. On November 22, 2023, at approximately 2:03 PM, a chlorinated secondary effluent spill occurred at the Warren facility due to a broken wash water line. Chlorinated secondary effluent flowed from the Warren Facility into an LA County flood control storm drain catch basin. The spill then flowed from the storm drain into the Wilmington Drain which discharges to Machado Lake. Sandbag containment was deployed at approximately 4:00 PM to completely stop the spill from entering the storm drain. The total amount of chlorinated secondary effluent that entered the storm drain is approximately 4500 gallons. Per Section 7.1.2.y of the permit, the Discharger shall notify the Manager of the Watershed Regulatory Section at the Los Angeles Water Board by telephone, within 24 hours of having knowledge of noncompliance and shall confirm this notification in writing within 5 days, unless the Los Angeles Water Board waives confirmation. LA Regional Water Quality Control Board staff was notified of the prohibited discharge on November 22, 2023, at 6:00 PM, within 24-hours of receiving the preliminary notification. An email confirmation of the notification was sent to the Regional Board on November 27, 2023, within 5 days of receiving the spill notification. No impacts to human health, the environment, or beneficial uses of surface water are anticipated from the incident. The discharge consisted of only disinfected secondary effluent, and residual chlorine was expected to have been reduced or otherwise dissipated in the storm drain before reaching Wilmington Drain over 3,600 feet away, or Machado Lake at almost 5,000 feet. No negative impacts were observed during biological observations taken on Thursday, November 23, 2023. Warren Facility maintenance staff replaced the corroded pipe to prevent reoccurrence.

1087636 12/31/2020 Surface Water The narrative receiving water objective was exceeded at receiving water station RSW-002D (R-B) for the month of December 2020. Regional Board staff was immediately notified by telephone at 1:15 PM on January 8, 2021, followed by written notification on January 8, 2021. Compliance was based on three valid Ceriodaphnia dubia chronic toxicity bioassays conducted in December using grab samples from receiving water station RSW-002D (R-B). The first toxicity test was initiated on December 9 using samples collected on December 8, 9, and 11. This test failed the Test of Significant Toxicity (TST) with 23.2% reproduction effect in the undiluted sample. The second test was initiated on December 22 using samples collected on December 21, 22, and 24. This test passed the TST for the reproduction endpoint with 20.2% effect observed in the undiluted sample. A third test was initiated on January 1, 2021 using samples collected on December 31 and January 1 and 5. This test failed the TST for the reproduction endpoint with 44.6% effect in undiluted effluent. As a result, the monthly median narrative objective was exceeded. RSW-002D (R-B) is currently the subject of a Toxicity Reduction Evaluation (TRE), which was triggered on February 27, 2020 in response to a single accelerated chronic toxicity test failing the TST. Steps 1 and 2 of the Detailed TRE Workplan were completed in April 2020, and Step 3 (Phase I Toxicity Identification Evaluation, TIE, testing) has continued through December; however, no causative agents have been identified yet. Because a separate TRE was being conducted for the Saugus WRP final effluent and it is the only known point source, the Sanitation District combined the two TRE Workplans to determine the cause of toxicity at both locations. The Sanitation Districts will continue to follow the submitted TRE Workplans and provide timely updates to the Regional Board. Violation N eSMR Saugus Water Reclamation Plant 396158 R4-2015-0072 N

1105406 03/31/2022 Deficient Monitoring For the sediment requirements there were deficient monitoring violations for stations RSW-4(4), RSW-W2(W-2), and RSW-LATT622(D). There are no results to report for the diazinon quarterly requirements for the January through March 2022 period and the pesticides semiannual requirements for the January through June 2022 period. The analysis for these constituents are contracted out. During this period, the Sample Receiving unit did not send the sample to the contract lab by mistake. By the time the Sample Receiving unit noticed, these samples were past their holding times. The permit specifies that quarterly and semiannual requirements must be conducted in the first quarter, so by the time this issue was noticed it was already past the first quarter and resampling was not possible. Although this will not meet the permit requirements, these stations will be analyzed in the second quarter for the semiannual requirements, and results will be provided as a sign of good faith. This resulted in 6 monitoring deficiencies, 3 will be reported in the January through March 2022 period and 3 will be reported in the January through June 2022. Violation N eSMR Donald C.

The sample was then shipped overnight to the BSK Fresno main laboratory. However, a Facility Code in the transit chain-of-custody was inadvertently left out for the Cyanide testing, thus failing to designate the Cyanide test to be performed by BSK-FAL, instead of BSK-RAL. Consequently, even though the sample arrived at BSK-FAL on 10/12/2022, and the Laboratory Information System (LIMS) had a Cyanide test logged in for the sample, the test did not show up amongst the worklists to be performed by the Wet Chemistry department at BSK-FAL. By the time this login error was discovered, the sample container was already disposed and the sample had already passed the 14 days holding time for Cyanide testing. When BSK notified us, it was too late to resample. There were no reported results for Cyanide in the month of October. Violation N eSMR Simi Valley WQCP 427894 R4-2019-0135 N

Consequently, no results were reported for total Kjeldahl nitrogen, organic nitrogen, and total nitrogen for the week of February 28 to March 6 resulting in 2 weekly monitoring deficiencies. The Wet Chemistry laboratory has been experiencing staff shortages due to the COVID-19 pandemic, which resulted in a growing backlog of samples to be analyzed. The Wet Chemistry supervisor prioritized analyses with short hold times. Despite best efforts to analyze all samples in a timely manner, both the supervisor of Wet Chemistry and the staff overlooked these particular samples. In addition, the samples were mistakenly put away in the back up refrigerator prior to analysis being completed on the samples. Violation N eSMR Donald C. Tillman WWRP 412169 R4-2017-0062 N

1100618 11/14/2021 Order Conditions An unauthorized recycled water discharge of approximately 40,500 gallons occurred on November 14 from roughly 11:00 p.m. to 6:30 a.m. on November 15 at the Sanitation Districts' Puente Hills Landfill located at 13130 Crossroads Parkway South in the City of Industry. The Sanitation Districts notified the Regional Board at 9:58 a.m. on November 16, and the LACDPH, via voicemail, immediately thereafter. Sanitation Districts staff discovered the discharge before normal business hours, at 5:30 a.m. on November 15. A damaged solenoid valve remained open, allowing 15 impact sprinklers to operate past their designated irrigation time for approximately 7.5 hours. An estimated 28,500 gallons infiltrated the ground prior to reaching a debris retention basin where an additional 2,000 gallons were collected and diverted to a sewer. The remaining 10,000 gallons travelled 1.13 miles to the San Jose Creek waterway. On November 15, at 1:50 p.m. the Sanitation Districts' Biological Sciences Group found normal dry-weather flow in the concrete channel, and no indications that wildlife had been adversely impacted. No major biological impacts are expected from this incident; chlorine demand exerted by substances along the discharge route is expected to have reduced any chlorine residual from the recycled water. To minimize reoccurrence of similar events, the Sanitation Districts will install automated meter reading systems with notification capabilities and will modify preventative maintenance schedules.

1108042 06/30/2022 Deficient Monitoring For the sediment requirements there were deficient monitoring violations for stations RSW-4(4), RSW-W2(W-2), and RSW-LATT622(D). There are no results to report for the pesticides semiannual requirements for the January through June 2022 period. The analysis for these constituents are contracted out. During this period, the Sample Receiving unit mistakenly did not send the sample to the contract lab. By the time the Sample Receiving unit noticed, these samples were past their holding times. The permit specifies that quarterly and semiannual requirements must be conducted in the first quarter, so by the time this issue was noticed it was already past the first quarter and resampling was not possible. This resulted in 3 monitoring deficiencies. Although this will not meet the permit requirements, these stations were analyzed in the second quarter for the semiannual requirements, and results were provided as a sign of good faith in the May 2022 report.

1109952 08/13/2022 Deficient Monitoring For the weekly lake requirements there were deficient monitoring violations for stations RSW-4(4) and RSW-W2(W-2). The sample for both RSW-4(4) and RSW-W2(W-2) on August 12 were not analyzed for total phosphorous, organic phosphorous, and condensed phosphorous within their holding time. On Thursday August 4 the boat used to collect samples broke its motor and propeller while attempting to collect sediment samples. The following week, the boat was still not repaired and the Department of Parks and Recreation staff collected the water quality sample on August 9 from the shoreline which was believed to be an alternate site. Correspondence was sent to the LA-RWQCB on August 9 notifying them that this location was used. The Regional Board replied on August 11 that the alternative site used in the past needs prior approval, so that sample was deemed not representative. Finally, the boat was repaired on Thursday August 11 and a sample was collected mid-lake at the permitted location on August 12. The laboratory had to scramble to conduct analysis for the compounds that have short holding times, such as the nutrients (nitrogen series and phosphorus series). Due to staff shortages, an analyst was pulled from another laboratory to conduct phosphate analysis. This analyst was under the impression that he was only coming in on Saturday to perform ortho-phosphorus on overtime. The analysis for total phosphorous, organic phosphorous, and condensed phosphorous were not analyzed that day and only discovered when the sample was past holding time. The root cause of this missed analysis is a lack of communication combined with staff shortages. This event also happened when the supervisor of the analysis lab was on vacation. This resulted in a deficient monitoring violation for stations RSW-4(4) and RSW-W2(W-2). Violation N eSMR Donald C. Tillman WWRP 412169 R4-2017-0062 N

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.

NPDES discharge from Discharge Point 001A occurred from August 4 to 15 during the semiannual period from July to December. A sample collected on August 8 from receiving water station RSW-006 (R-12) for acrolein was invalid because the sample was not analyzed within the appropriate laboratory holding time. To prevent reoccurrence, Laboratory staff have reviewed the analysis procedure and were reminded of the appropriate holding time. Make-up sample collection was attempted on December 19, but the location was dry at the time of sampling. Therefore, there is no result for acrolein for the July to December semiannual period.

1108043 06/30/2022 Deficient Monitoring For the sediment requirements there were deficient monitoring violations for stations RSW-4(4), RSW-W2(W-2), and RSW-LATT622(D). There are no results to report for the pesticides semiannual requirements for the January through June 2022 period. The analysis for these constituents are contracted out. During this period, the Sample Receiving unit mistakenly did not send the sample to the contract lab. By the time the Sample Receiving unit noticed, these samples were past their holding times. The permit specifies that quarterly and semiannual requirements must be conducted in the first quarter, so by the time this issue was noticed it was already past the first quarter and resampling was not possible. This resulted in 3 monitoring deficiencies. Although this will not meet the permit requirements, these stations were analyzed in the second quarter for the semiannual requirements, and results were provided as a sign of good faith in the May 2022 report.

1105407 03/31/2022 Deficient Monitoring For the sediment requirements there were deficient monitoring violations for stations RSW-4(4), RSW-W2(W-2), and RSW-LATT622(D). There are no results to report for the diazinon quarterly requirements for the January through March 2022 period and the pesticides semiannual requirements for the January through June 2022 period. The analysis for these constituents are contracted out. During this period, the Sample Receiving unit did not send the sample to the contract lab by mistake. By the time the Sample Receiving unit noticed, these samples were past their holding times. The permit specifies that quarterly and semiannual requirements must be conducted in the first quarter, so by the time this issue was noticed it was already past the first quarter and resampling was not possible. Although this will not meet the permit requirements, these stations will be analyzed in the second quarter for the semiannual requirements, and results will be provided as a sign of good faith. This resulted in 6 monitoring deficiencies, 3 will be reported in the January through March 2022 period and 3 will be reported in the January through June 2022. Violation N eSMR Donald C.

1123165 10/18/2023 Surface Water Per Section 5.1.21 of the WDR, there shall be no chronic toxicity in ambient waters as a result of wastes discharged. 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. Two subsequent chronic toxicity compliance samples were taken in October and passed the TST (see details in the Receiving Water section below). Effluent toxicity samples for the month of October passed the TST with a -1.3% reproduction effect and -5.3% survival effect. Violation N eSMR Long Beach WRP 447474 R4-2022-0032 N

In February, effluent samples were inadvertently not collected or analyzed for dissolved oxygen. A make-up sample will be collected in May and the result will be included in the May monthly compliance report. As a corrective action, a senior analyst will double check with the technicians for all pending analysis before the end of each month and the lab will utilize the search function in the Laboratory Information Management System (LIMS) to weed out any pending samples/analysis after their routine monthly collection. The lab will also verify the correct sample bottle is being used both before and after the extraction process, and following the completion of the analysis, a peer review will be promptly conducted.

1089986 02/07/2021 Order Conditions An unauthorized recycled water discharge of approximately 237,105 gallons occurred from roughly 7:21 p.m. to 9:01 p.m. on February 7, 2021 at the Sanitation Districts' Puente Hills Landfill, located at 13130 Crossroads Parkway South in the City of Industry. The Sanitation Districts notified the Regional Board at 7:58 a.m. on February 9, 2021 and the LACDPH, via email, at 8:06 a.m. on the same day. Sanitation Districts staff discovered the discharge during normal business hours at 8:12 a.m. on Monday, February 8, 2021. The failure of a high-level sensor and relay switch during a temporary network communications outage allowed a recycled water storage tank to overfill for approximately 100 minutes; 179,520 gallons of this discharge were recovered and pumped to a sewer from a concrete-lined debris basin. On February 8, 2021 at 9:29 a.m., the Sanitation District Biology Group found no flow in the channel, no evidence of discharge flow at the San Gabriel River discharge point, and no indications that fish or wildlife had been adversely impacted. No major impacts are anticipated from this incident; chlorine demand exerted by substances along the discharge route is expected to have reduced any chlorine residual from the recycled water. To minimize reoccurrence of similar events, the Sanitation Districts will modify and increase the frequency of related preventative maintenance work orders.

This scheduling error was associated with the new monitoring and reporting requirements of Order R4-2022-0032, which became effective in April 2022. The monthly effluent chloride sample in June was 156 mg/L, which is below the monthly average effluent limit and Basin Plan recommended objective of 230 mg/L. Laboratory staff have reviewed their sample collection schedules and have updated those schedules accordingly so that this sampling event will not be missed in the future.

1102045 12/31/2021 Deficient Monitoring For the NPDES semiannual effluent requirements there was one deficient monitoring violation for perchlorate for the July through December 2021 period. A 24-hour composite sample was analyzed in the third quarter for perchlorate instead of a grab sample as specified in the NPDES permit. A composite sample is legally valid per the analytical EPA method 314.0 used by the laboratory. During this time there was a significant increase in the frequency of monitoring in the Santa Monica Bay per order R4-2021-0107-A02 because of the sewage discharge from the Hyperion Water Reclamation Plant on July 12 of 2021, which resulted in a growing backlog of samples to be analyzed by the Wet Chemistry lab. The composite sample from DCTWRP was analyzed instead of the grab sample and the lab could not spare the resources to resample and reanalyze. The composite sample had an estimated concentration of 0.68 ug/L. While valid, the NPDES permit requires for perchlorate to be analyzed on an effluent grab sample. Perchlorate is monitored more frequently than required in the NPDES permit. An effluent grab sample was also sampled and analyzed in the fourth quarter. The result for the effluent grab sample was reported in the semiannual discharge monitoring report. Although a correct sample type was analyzed for perchlorate in the period of July through December 2021, this still resulted in a semiannual deficient monitoring violation since the analysis was not conducted on a third quarter sample as required by the NPDES permit.

Therefore, this result was expected to be within normal range. To prevent a recurrence of this issue, Laboratory senior staff revisited the procedure with the analyst.

1088879 01/03/2021 Deficient Monitoring Per Section IV.A.2 of the MRP, additional effluent samples shall be collected and analyzed for residual chlorine if the residual chlorine meter reads greater than 0.3 mg/L for more than five minutes. 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. To prevent this issue from re-occurring, notification and sample collection procedures have been reviewed with operational and laboratory supervisory staff.

1105405 03/31/2022 Deficient Monitoring For the sediment requirements there were deficient monitoring violations for stations RSW-4(4), RSW-W2(W-2), and RSW-LATT622(D). There are no results to report for the diazinon quarterly requirements for the January through March 2022 period and the pesticides semiannual requirements for the January through June 2022 period. The analysis for these constituents are contracted out. During this period, the Sample Receiving unit did not send the sample to the contract lab by mistake. By the time the Sample Receiving unit noticed, these samples were past their holding times. The permit specifies that quarterly and semiannual requirements must be conducted in the first quarter, so by the time this issue was noticed it was already past the first quarter and resampling was not possible. Although this will not meet the permit requirements, these stations will be analyzed in the second quarter for the semiannual requirements, and results will be provided as a sign of good faith. This resulted in 6 monitoring deficiencies, 3 will be reported in the January through March 2022 period and 3 will be reported in the January through June 2022. Violation N eSMR Donald C.

1127987 07/22/2023 Order Conditions An unauthorized recycled water discharge of approximately 63,000 gallons occurred on July 22 near the intersection of The Old Road and Valencia Boulevard. The discharge was due to a car accident which sheared a SCVWA recycled water air vacuum valve. Soon after the accident, SCVWA staff arrived onsite and began assessing how to isolate the valve. Due to the location of the leak, it could not be immediately isolated. The discharge likely traveled approximately 1.12 miles in the storm drain and discharged into the Santa Clara River. No adverse effects were observed, nor would they be expected because the discharge was disinfected tertiary treated recycled water and any residual chloride would have dissipated due to contact with substances exerting chlorine demand along the discharge route. SCVWA reported the discharge to the Sanitation District at 1:43 p.m. on July 24, and the Sanitation District notified the Regional Board via email at 3:55 p.m. on July 24 with a follow-up phone call at 3:39 p.m. on July 25.

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.

1088876 01/31/2021 Surface Water The narrative receiving water objective was exceeded at receiving water station RSW-002D (R-B) for the month of January 2021. Regional Board staff was immediately notified by telephone at 7:08 a.m. on January 27, 2021, followed by written notification on January 28, 2021. Compliance was based on two valid Ceriodaphnia dubia chronic toxicity bioassays conducted in January using grab samples from receiving water station RSW-002D (R-B). The first toxicity test was initiated on January 5 using samples collected on January 4, 6, and 8. This test failed the Test of Significant Toxicity (TST) with 57.4% reproduction effect in the undiluted sample. The second test was initiated on January 19 using samples collected on January 18, 19, and 21. This test failed the TST for the reproduction endpoint with 72.5% effect observed in the undiluted sample. As a result, the monthly median narrative objective was exceeded. RSW-002D (R-B) is currently the subject of a Toxicity Reduction Evaluation (TRE), which was triggered on February 27, 2020 in response to a single accelerated chronic toxicity test failing the TST. Steps 1 and 2 of the Detailed TRE Workplan were completed in April 2020, and Step 3 (Phase I Toxicity Identification Evaluation, TIE, testing) has continued through December; however, no causative agents have been identified yet. Because a separate TRE was being conducted for the Saugus WRP final effluent and it is the only known point source, the Sanitation District combined the two TRE Workplans to determine the cause of toxicity at both locations. The Sanitation Districts will continue to follow the submitted TRE Workplans and provide timely updates to the Regional Board. Violation N eSMR Saugus Water Reclamation Plant 396158 R4-2015-0072 N

1119966 06/30/2023 Deficient Monitoring For the monthly effluent requirements there was a deficient monitoring violation for pentachlorophenol. Per the DCTWRP permit Order No. R4-2022-0341 effective February 1, 2023, pentachlorophenol is a monthly required constituent with an effluent limit of 1.0 ug/L. Due to the in-house method not being sensitive enough to determine compliance with the new effluent limit, monthly analysis has been contracted out. The contract lab extracted the sample outside the allowed holding time. The contract lab sent out an update once the month of June had passed, so resampling was not possible. This resulted in a deficient monitoring violation for pentachlorophenol. Violation N eSMR Donald C. Tillman WWRP 447892 R4-2022-0341 N

1102047 12/31/2021 Deficient Monitoring For the NPDES semiannual effluent requirements there was one deficient monitoring violation for perchlorate for the July through December 2021 period. A 24-hour composite sample was analyzed in the third quarter for perchlorate instead of a grab sample as specified in the NPDES permit. A composite sample is legally valid per the analytical EPA method 314.0 used by the laboratory. During this time there was a significant increase in the frequency of monitoring in the Santa Monica Bay per order R4-2021-0107-A02 because of the sewage discharge from the Hyperion Water Reclamation Plant on July 12 of 2021, which resulted in a growing backlog of samples to be analyzed by the Wet Chemistry lab. The composite sample from LAGWRP was analyzed instead of the grab sample and the lab could not spare the resources to resample and reanalyze. The composite sample had a non-detect result. While valid, the NPDES permit requires for perchlorate to be analyzed on an effluent grab sample. Perchlorate is monitored more frequently than required in the NPDES permit. An effluent grab sample was also sampled and analyzed in the fourth quarter. The result for the effluent grab sample was reported in the semiannual discharge monitoring report. Although a correct sample type was analyzed for perchlorate in the period of July through December 2021, this still resulted in a semiannual deficient monitoring violation since the analysis was not conducted on a third quarter sample as required by the NPDES permit.

The samples taken on March 2, 2021, were not analyzed for total Kjeldahl nitrogen within their 28 day holding time. Consequently, no results were reported for total Kjeldahl nitrogen, organic nitrogen, and total nitrogen for the week of February 28 to March 6 resulting in 2 weekly monitoring deficiencies. The Wet Chemistry laboratory has been experiencing staff shortages due to the COVID-19 pandemic, which resulted in a growing backlog of samples to be analyzed. The Wet Chemistry supervisor prioritized analyses with short hold times. Despite best efforts to analyze all samples in a timely manner, both the supervisor of Wet Chemistry and the staff overlooked these particular samples. In addition, the samples were mistakenly put away in the back up refrigerator prior to analysis being completed on the samples. Violation N eSMR Donald C. Tillman WWRP 412169 R4-2017-0062 N

1108041 06/30/2022 Deficient Monitoring For the sediment requirements there were deficient monitoring violations for stations RSW-4(4), RSW-W2(W-2), and RSW-LATT622(D). There are no results to report for the pesticides semiannual requirements for the January through June 2022 period. The analysis for these constituents are contracted out. During this period, the Sample Receiving unit mistakenly did not send the sample to the contract lab. By the time the Sample Receiving unit noticed, these samples were past their holding times. The permit specifies that quarterly and semiannual requirements must be conducted in the first quarter, so by the time this issue was noticed it was already past the first quarter and resampling was not possible. This resulted in 3 monitoring deficiencies. Although this will not meet the permit requirements, these stations were analyzed in the second quarter for the semiannual requirements, and results were provided as a sign of good faith in the May 2022 report.

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
