Deficient Monitoring |
On 6/28/25, the autosampler at INF-004 failed and no sample was collected. Because there was no composite sample, daily BOD and TSS could not be analyzed therefore resulting in a monitoring deficiency. |

Deficient Monitoring |
The influent flow meter was calibrated on April 21, 2025. There was, however, an issue with the influent flow meter, which was addressed on May 7, 2025. 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). This resulted in one deficiency in monitoring for May 2025. |

Deficient Monitoring |
For the NPDES weekly lake requirement for RSW-4(4) there was a deficient monitoring violation for dissolved oxygen. The sample taken on October 1, 2024, was analyzed for dissolved oxygen, but the analyst recorded the incorrect meter display. The result for that day was reported as analyst error for dissolved oxygen. That resulted in one monitoring deficiency for the week of September 29 to October 5. |

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 September 3, 2024, were not analyzed for total kjeldahl nitrogen and organic nitrogen within their holding time. The samples were put away prematurely before conducting all the required analysis, resulting in the samples being past holding time. Consequently, no results were reported for total kjeldahl nitrogen, organic nitrogen, and total nitrogen for the week of September 1 to September 7 resulting in 1 weekly monitoring deficiencies. |

The flow meter discharging into Balboa Lake stopped working on July 26, 2023. 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. |

The flow meter discharging into Balboa Lake stopped working on July 26, 2023. 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. |

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. |

Per the DCTWRP permit Order No. R4-2022-0341 effective February 1, 2023, carbon tetrachloride is a monthly required constituent with an effluent limit of 0.5 ug/L. In February and March, it was analyzed at the correct frequency, but not analyzed in April. Typically, two samples, one acidified and one not, are required for full EPA 624.1 analysis. The analyst was unaware of the effluent limitation on a single compound and assumed there would be a second sample for routine analysis, and did not analyze the sample. This resulted in one deficient monitoring violation. |

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. |

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). |

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. |

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. |

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. |

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. |

On July 11, 2021, an excessive amount of debris suddenly collected on the barscreens of Hyperion's Headworks Screening Facility. 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. Additionally, average and maximum flows for 7/11 and 7/12 are Not Representative. |

The average and maximum daily flows through the 5-Mile Outfall cannot be calculated on 7/11/2021 and 7/12/2021. Therefore, mass loadings for BOD and TSS cannot be reported. Settleable Solids and Turbidity were not sampled on 7/12/2021. Effluent temperature cannot be reported after 7/12/2021 for the month of July due to equipment damage.

Deficient Monitoring |
On July 11, 2021, an excessive amount of debris suddenly collected on the barscreens of Hyperion¿s Headworks Screening Facility. 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-005 on 7/12/2021. This is a deficient monitoring violation for analyses required daily: TSS and BOD. Additionally, average and maximum flows for 7/11 and 7/12 are Not Representative. |

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. |

Deficient Monitoring |
On April 2 of 2021, the LAGWRP effluent grab sample was not analyzed for total residual chlorine which is a daily requirement Monday through Friday only, except for holidays. Due to the COVID-19 pandemic, the City of Los Angeles has been experiencing financial hardship, and, as a cost-saving measure, has adopted unpaid holidays for the majority of the city employees. April 2 was one of those unpaid holidays and the laboratory was staffed for the weekend schedule. This resulted in a deficient monitoring violation for total residual chlorine. |

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. |

Deficient Monitoring |
The Los Angeles Harbor testing of HW-20 and HW-62 for chronic toxicity, and the concurrent effluent chronic toxicity testing, occurred late in February, with samples collected on the 22nd for the Harbor sites and the 21st for effluent. The reference toxicant test for this batch of samples failed, rendering the toxicity results invalid, and a re-sampling could not occur before the end of the month. This is a deficient monitoring violation as effluent chronic toxicity testing is required monthly. |
