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. |
In order to prevent recurrence in the future, EMD has amended our send out procedure for receiving water samples. We also added a send out chain of custody to our July folder as well as included it in our send out checklist file for July, so that we are on alert if the receiving water chronic toxicity sampling is conducted. |

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. |

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. |

For the NPDES monthly effluent requirements there was one deficient monitoring violation for dieldrin 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. There are no results to report in May. |

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. |
The laboratory supervisor was informed that although on unpaid holidays they are staffed for the weekend schedule, all Monday through Friday requirements in the permit must be met. The laboratory staff was also reminded of the daily requirements in order to prevent recurrence. |

In February, there was a deficient monitoring violation for total nitrogen, which is required monthly for the NPDES permit. There was a resample for Nitrate-N and Nitrite-N. The resample was taken for only Nitrate-N and Nitrite-N. Since all the nitrogen constituents were not analyzed on the same day, total nitrogen was not able to be calculated. |
Similar total nitrogen deficient monitoring violations occurred at Donald C. Tillman Water Reclamation Plant in January and February of 2021. After all of these occurrences, a note was made on the chain of custody template and the analyzing lab¿s supervisor made a change in his review procedure in order to prevent a reoccurrence. |

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. |
To avoid this in the future, sample batching will be approved by the supervisor prior to processing for inexperienced staff. |

On November 4, 2019 the effluent Oil and Grease sample was analyzed past its holding time. The result was reported as an analyst error (AE). Oil and Grease, which is a weekly requirement for the effluent, was not analyzed for the week of November 3-9 of 2019. This AE resulted in a deficient monitoring violation for the week of November 3-9. At the end of November, the Wet Chemistry lab received a large influx of stormwater samples that were prioritized. These "Rush" samples were analyzed first. In doing so, analysts overlooked the sample dates of the samples collected early November. |
Corrective actions have been put in place to avoid these occurrences in the future. Staff have been informed to pay close attention to sample collection dates on sample bottles and to always analyze the oldest samples first. Staff have also been given instructions to notify the supervisor of any samples that may be close to holding time expiration. In doing so, the supervisor will shift staff schedules to avoid having any samples analyzed past holding time. |
