The barscreens were overwhelmed, causing flooding of the Treatment Plant and discharge of approximately 17 million gallons of untreated wastewater via the storm drain system to the 1-Mile Outfall. Flooding of the pipe galleries and equipment caused significant damage and degraded Hyperion¿s treatment processes, resulting in effluent violations throughout the month of July. No sample could be collected at the legally mandated sampling point for INF-001 on 7/12/2021. This is a deficient monitoring violation for analyses required daily: TSS and BOD.

Violation N eSMR Terminal Island Water Reclamation Plant 399400 R4-2015-0119 N 1111239 09/30/2022 Deficient Monitoring For the receiving water requirements there were two deficient monitoring violations for stations RSW-LAGT650 and RSW-LAGT654(a) for the July through September 2022 period. The quarterly diazinon monitoring for these stations was not conducted concurrently with the receiving water chronic toxicity sampling. Although both of these constituents were monitored during the July through September period, meeting the minimum sampling frequency required by the permit, the permit specifies diazinon sampling shall be conducted concurrently with the receiving water chronic toxicity sampling. This resulted in two monitoring deficiencies. These deficiencies will be reported in the September 2022 report which is with the July through September 2022 quarterly period. Violation N eSMR Los Angeles-Glendale WWRP 407633 R4-2017-0063 N 1070666 11/03/2019 Deficient Monitoring At the end of November, Wet Chemistry section received a large influx of storm-water samples from HTP, LAG, DCT, and WPD. Because these are ¿rush¿ samples, the analyst analyzed these first. In doing so, the sample dates of the samples collected early November were overlooked and their holding times were exceeded. November 3 effluent oil and grease sample was analyzed out of holding time due to human error. This sample was accidentally put away in Wet Chemistry''s back up refrigerator and was noticed by someone else close to the expiration date of the sample. We analyzed the sample immediately once the error was realized. Unfortunately, the error was caught late and the result is being reported as ¿Analyst Error (AE)¿. All of the rest of 3 weekly results are ¿Not Detected (ND)¿ or ¿Detected but Not Quantified (DNQ)¿; therefore, the monthly median of this month is ND and in compliance of permit limit 10 mg/L.

The sample taken on July 7, 2020, was not analyzed for organic Nitrogen within the 28 day holding time. As a result no results were reported for the organic nitrogen for the week of July 5-11 resulting in 1 weekly monitoring deficiency. Also for the week of July 5-11, since there were no results for organic nitrogen, total nitrogen was not able to be calculated which resulted in 1 more weekly monitoring deficiency. The samples taken on July 14, 2020, were not analyzed for Nitrate-N and Nitrite-N within their 48 hours holding time. There was a resample on July 17, 2020 for only Nitrate-N and Nitrite-N. Since all the nitrogen constituents in the week of July 12-18 were not analyzed on the same day, total nitrogen was not able to be calculated which resulted in 1 more weekly monitoring deficiency.

Violation N eSMR Hyperion WWTP 447793 R4-2023-0033 N 1082477 09/13/2020 Deficient Monitoring For the weeks of September 13-19 and 20-26 both stations RSW-4(4) and RSW-W2(W-2) were not sampled for any of their weekly requirements. For those two weeks there are no results for pH, temperature, dissolved oxygen, total nitrogen, TKN, ammonia nitrogen, organic nitrogen, nitrate nitrogen, nitrite nitrogen, total phosphorus, organic phosphorus, condensed phosphorus, and orthophosphorus. Boat malfunctions led to missed weekly sampling of stations RSW-4(4) and RSW-W2(W-2) for a duration of two weeks before the Department of Recreation and Parks could acquire and affix a loaned engine to one of the boats. Sampling resumed and the original engines were fixed in October. As weekly sampling of both monitoring locations are required in the DCTWRP NPDES discharge permit, alternate sites accessible by sampling pole from the shoreline were sampled until one of the boats was repaired. An alternate sampling location for RSW-W2(W-2) has already been approved previously (August 2, 2019). An approved alternate location for RSW-4(4) does not currently exist, but a suitable location has been determined to proceed with mandated weekly sampling. Due to both the approved alternate location for RSW-W2(W-2) and the unapproved alternate location of RSW-4(4) not being in the California Integrated Water Quality System, these weekly results were submitted as an attachment with this monthly report. Since these results are a weekly NPDES requirement for RSW-4(4) and were taken from an unapproved alternate site, this resulted in a deficient monitoring violation for station RSW-4(4) for the month of September.

Effluent flow is a continuous monitoring requirement reported on a daily basis for the daily average flow and daily maximum flow. The daily average effluent flows being reported for effluent discharge starting on July 25, 2023 are approximate values. The flow to Balboa Lake is being estimated based on pump capacity. Until the meter is replaced, the reported daily average flow for the effluent will continue to be an approximate value. Due to the Balboa Lake meter not working, the daily maximum for the effluent flow cannot be determined, these have been reported as an instrument failure (IF) since July 25, 2023. This IF resulted in one deficient monitoring violation for February 2024. Violation N eSMR Donald C. Tillman WWRP 447892 R4-2022-0341 N 1072650 12/23/2019 Deficient Monitoring On December 23th, five influent and one effluent total suspended solids composite samples were reported as ¿Analyst Error (AE)¿. The analyst lost the dry weights of those samples and data could not be recovered from LIMS. Therefore, suspended solids could not be calculated from dry weight. Loading on that day could not be calculated. The plant was in normal operation at the time and effluent suspended solids from the previous and subsequent day were 21 mg/L and 20 mg/L, respectively. The monthly average was 18 mg/L and in compliance.

Equipment necessary for profiling and sampling was unavailable due to Coronavirus closures. See attached letter to Regional Board dated June 30 titled ¿Unable to perform quarterly offshore and harbor water quality monitoring (April ¿ June)¿. Conductivity-temperature-depth (CTD) profiler was out of service and under repair at Sea-Bird Facility in Washington State, which was shut down during the pandemic. The CTD profiler is used for both discrete and surface sampling. Without the use of a CTD for tracking and delineating the plume, surface sample collection involving ammonia and microbiological samples would not be meaningful.

The secondary boat is also out-of-service with a necessary part on back-order. Both sampling locations are located offshore in deeper water and accessible only by boat. As weekly sampling of both monitoring locations are required in the DCTWRP NPDES discharge permit, alternate sites accessible by sampling pole from the shoreline will be sampled until at least one of the boats is repaired. An approved alternate location for RSW-4 does not currently exist, but a suitable location has been determined to proceed with mandated weekly sampling. Due to the unapproved alternate location of RSW-4 not being in the California Integrated Water Quality System, these weekly nitrogen nutrients results were submitted as an attachment with this monthly report. Since these results are a weekly NPDES requirement for RSW-4 and were taken from an unapproved alternate site, this resulted in six deficient monitoring violations for the week of April 26 to May 2 of 2020 for nitrogen nutrients. The six deficient monitoring violations were for total nitrogen, total kjeldahl nitrogen, ammonia nitrogen, organic nitrogen, nitrate nitrogen, and nitrite nitrogen. Violation N eSMR Donald C.

The barscreens were overwhelmed, causing flooding of the Treatment Plant and discharge of approximately 17 million gallons of untreated wastewater via the storm drain system to the 1-Mile Outfall. Flooding of the pipe galleries and equipment caused significant damage and degraded Hyperion's treatment processes, resulting in effluent violations throughout the month of July. There was no wastewater flow through the 1-Mile sampling point and no sample could be collected at the legally mandated sampling point during the discharge. This is a deficient monitoring violation.

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.

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.

The quarterly diazinon monitoring for these stations was not conducted concurrently with the receiving water chronic toxicity sampling. Although both of these constituents were monitored during the July through September period, meeting the minimum sampling frequency required by the permit, the permit specifies diazinon sampling shall be conducted concurrently with the receiving water chronic toxicity sampling.

Due to the unapproved alternate location of RSW-4 not being in the California Integrated Water Quality System, these weekly nitrogen nutrients results were submitted as an attachment with this monthly report. Since these results are a weekly NPDES requirement for RSW-4 and were taken from an unapproved alternate site, this resulted in six deficient monitoring violations for the week of April 26 to May 2 of 2020 for nitrogen nutrients.

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.

Conductivity-temperature-depth (CTD) profiler was out of service and under repair at Sea-Bird Facility in Washington State, which was shut down during the pandemic. The CTD profiler is used for both discrete and surface sampling. Without the use of a CTD for tracking and delineating the plume, surface sample collection involving ammonia and microbiological samples would not be meaningful.

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.

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.

Violation N eSMR Hyperion WWTP 447793 R4-2023-0033 N 1072654 11/19/2019 Deficient Monitoring On November 20th, during the initial set-up of the November 19th INF-004(NOS) influent composite sample for BOD, the analyst didn't add the actual NOS sample to the BOD bottle, which caused the 5-day BOD result to be as low as the method blank. The BOD result was reported as Analyst Error (AE). The 5-mile effluent (EFF-002) BOD result was 17 mg/L and in normal range. Violation N eSMR Hyperion WWTP 384601 R4-2017-0045 N 1076849 04/28/2020 Deficient Monitoring On April 28, 2020 Los Angeles City Department of Recreation and Parks staff attempting to sample stations RSW-4 and RSW-W2 discovered the boat engine was inoperable. The secondary boat is also out-of-service with a necessary part on back-order. Both sampling locations are located offshore in deeper water and accessible only by boat. As weekly sampling of both monitoring locations are required in the DCTWRP NPDES discharge permit, alternate sites accessible by sampling pole from the shoreline will be sampled until at least one of the boats is repaired. An approved alternate location for RSW-4 does not currently exist, but a suitable location has been determined to proceed with mandated weekly sampling. Due to the unapproved alternate location of RSW-4 not being in the California Integrated Water Quality System, these weekly nitrogen nutrients results were submitted as an attachment with this monthly report. Since these results are a weekly NPDES requirement for RSW-4 and were taken from an unapproved alternate site, this resulted in six deficient monitoring violations for the week of April 26 to May 2 of 2020 for nitrogen nutrients. The six deficient monitoring violations were for total nitrogen, total kjeldahl nitrogen, ammonia nitrogen, organic nitrogen, nitrate nitrogen, and nitrite nitrogen. Violation N eSMR Donald C.

Violation N eSMR Hyperion WWTP 384601 R4-2017-0045 N 1089847 02/28/2021 Deficient Monitoring In February, there was a deficient monitoring violation for total nitrogen, which is required monthly for the NPDES permit. The schedule sampling date for Ammonia and Organic Nitrogen had to be postponed due to the plant not discharging effluent because of a turbidity issue. Since all the nitrogen constituents were not analyzed on the same day, total nitrogen was not able to be calculated. Violation N eSMR Donald C. Tillman WWRP 412169 R4-2017-0062 N 1071570 12/23/2019 Deficient Monitoring On December 23th, five influent and one effluent total suspended solids composite samples were reported as ¿Analyst Error (AE)¿. The analyst lost the dry weights of those samples and data could not be recovered from LIMS. Therefore, suspended solids could not be calculated from dry weight. Loading on that day could not be calculated. The plant was in normal operation at the time and effluent suspended solids from the previous and subsequent day were 21 mg/L and 20 mg/L, respectively. The monthly average was 18 mg/L and in compliance. Violation N eSMR Hyperion WWTP 384601 R4-2017-0045 N 1112236 10/16/2022 Deficient Monitoring There was an autosampler malfunction and no sample could be collected October 16, 2022 for INF-001. Monitoring of suspended solids and biochemical oxygen demand are required daily for each individual influent sewer. Violation N eSMR Hyperion WWTP 384601 R4-2017-0045 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 1102968 01/28/2022 Deficient Monitoring On January 28, all influent and effluent biological oxygen demand results were invalid due to quality control (QC) failures. Violation N eSMR Hyperion WWTP 384601 R4-2017-0045 N 1076851 04/28/2020 Deficient Monitoring On April 28, 2020 Los Angeles City Department of Recreation and Parks staff attempting to sample stations RSW-4 and RSW-W2 discovered the boat engine was inoperable. The secondary boat is also out-of-service with a necessary part on back-order. Both sampling locations are located offshore in deeper water and accessible only by boat. As weekly sampling of both monitoring locations are required in the DCTWRP NPDES discharge permit, alternate sites accessible by sampling pole from the shoreline will be sampled until at least one of the boats is repaired. An approved alternate location for RSW-4 does not currently exist, but a suitable location has been determined to proceed with mandated weekly sampling. Due to the unapproved alternate location of RSW-4 not being in the California Integrated Water Quality System, these weekly nitrogen nutrients results were submitted as an attachment with this monthly report. Since these results are a weekly NPDES requirement for RSW-4 and were taken from an unapproved alternate site, this resulted in six deficient monitoring violations for the week of April 26 to May 2 of 2020 for nitrogen nutrients. The six deficient monitoring violations were for total nitrogen, total kjeldahl nitrogen, ammonia nitrogen, organic nitrogen, nitrate nitrogen, and nitrite nitrogen. Violation N eSMR Donald C.

The sample taken on July 7, 2020, was not analyzed for organic Nitrogen within the 28 day holding time. As a result no results were reported for the organic nitrogen for the week of July 5-11 resulting in 1 weekly monitoring deficiency. Also for the week of July 5-11, since there were no results for organic nitrogen, total nitrogen was not able to be calculated which resulted in 1 more weekly monitoring deficiency. The samples taken on July 14, 2020, were not analyzed for Nitrate-N and Nitrite-N within their 48 hours holding time. There was a resample on July 17, 2020 for only Nitrate-N and Nitrite-N. Since all the nitrogen constituents in the week of July 12-18 were not analyzed on the same day, total nitrogen was not able to be calculated which resulted in 1 more weekly monitoring deficiency. Violation N eSMR Donald C. Tillman WWRP 412169 R4-2017-0062 N 1076852 04/06/2020 Deficient Monitoring The April 6, 2020 LAG effluent sample for Oil and Grease, was reported as an analyst error (AE). The recovery data for the LFB quality control sample fell outside the acceptable range rendering the data for the entire batch unreliable and non-reportable. Due to staffing issues surrounding the COVID-19 pandemic, we are training new staff from other sections on various analyses. This inexperienced analyst used all back-up samples as fortified matrix duplicates within this batch. As a weekly NPDES requirement, we were unable to resample for the week of April 5-11 of 2020. This AE resulted in a deficient monitoring violation for the week of April 5-11.

The analyst continued trying to achieve a stabilized reading for three hours. The lab reported the result as an analyst error (AE). DO is a weekly requirement for the effluent, this AE resulted in a deficient monitoring violation for the week of May12-18.

Violation N eSMR Hyperion WWTP 447793 R4-2023-0033 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. Violation N eSMR Los Angeles-Glendale WWRP 407633 R4-2017-0063 N 1090989 03/06/2021 Deficient Monitoring For the NPDES weekly lake requirement for RSW-4(4) and RSW-W2 (W-2) there were deficient monitoring violations. 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. Violation N eSMR Donald C. Tillman WWRP 412169 R4-2017-0062 N 1079178 06/14/2020 Deficient Monitoring The CIWS BOD sample prepared on June 15, with a calculated result on June 20, showed no oxygen depletion. This result indicated that perhaps the CIWS sample was not added to the two sample bottles in the June 15 preparation; therefore, this result was reported as ¿Analyst Error AE¿. The 5-mile BOD result on that day was 19 mg/L and in normal range. Violation N eSMR Hyperion WWTP 384601 R4-2017-0045 N 1119141 05/31/2023 Deficient Monitoring Two new requirements in the effective NPDES permit were missed in May, but corrected in June: the monitoring of copper in influent and organic-nitrogen in effluent. Both of these analyses are required monthly. Organic-nitrogen is required to calculate total nitrogen, another monthly requirement. Violation N eSMR Hyperion WWTP 447793 R4-2023-0033 N 1093974 06/30/2021 Deficient Monitoring For the NPDES quarterly receiving water requirements there was a deficient monitoring violation for dieldrin for both stations RSW-LAGT650 (R-4) and RSW-LAGT654(a) (R-7) due to a laboratory error. During the analysis, the sample was spiked in error with the target analyte instead of the required surrogates and the results are not reportable. A resample was not requested by the laboratory, so there are no results to report for the second quarter of April to June.
