Deficient Monitoring |
On August 4, 2025, Plant MNWD-3A (M-001C) operations staff mistakenly did not submit a secondary effluent composite sample. This was due to using the wrong bottle for sample collection. Operations staff discarded the composite sample for the day and forgot to conduct a makeup sample later in the week. This resulted in a missed monitoring event for the R9-2025-0001 permit. Operations staff collected the secondary effluent daily composite sample in the incorrect sample bottles. The contracted laboratory provides premade sample kits for each compliance sample day. The collected sample was deemed unusable as it was put into the incorrect bottle which contained preservative for a different analysis at another sample location; therefore, the sample was discarded because it was now contaminated. Operations staff forgot to schedule a makeup sample collection for this later in the week. |

Unauthorized Discharge |
On Friday, July 11, 2025 at approximately 9:50am, a contractor onsite at MNWD's Plant 3A (26801 Camino Capistrano, Mission Viejo CA) opened an incorrect pipe connected to a digester. Liquid from the digester flowed until the pipe was able to be re-capped around 10:30 am. Total spill volume was calculated at 18,548 gallons of liquid that left the digester. Dirt berms were used to contain flow as best as possible, but approximately 300 gallons did enter a storm drain and subsequently Oso Creek. It was calculated that 18,280 gallons were recovered. MNWD staff set up a portable dam in the Oso Creek channel downstream, equipped with a portable pump, and began pumping this flow into a nearby sewer manhole to return to a treatment plant. Staff observations did not note any downstream impacts during bypass pumping, which continued for approximately 30 hours, removing approximately 630,000 gallons of water over that time period. Surface water sampling was conducted same-day and additionally 2 days of follow up sampling. |

The City of San Clemente, M-INFD, did set up an Influent cBOD that week of 7/19 but the tech was out the following week due to an accident and was unable to complete the analysis. The tech normally setup Influent cBOD twice a week to ensure that they have at least one data point but he happened to be out that Thursday which is the day the tech normally setup the additional Influent cBOD. |

I am writing to inform you that the 3A (M-001C) monthly samples from November 4th and November 5th are missing total suspended solids (TSS) analysis. The laboratory reports from the subcontracted lab note that: Please note, while TSS was requested on the sample, the laboratory stated there was not enough sample volume remaining in order to perform the TSS analysis. Sierra was not made aware of this issue until December 11, 2024 which did not allow them enough time to resample. |

Monthly Effluent Oil and Grease was not monitored in December 2022 for location M-001E(San Juan Capistrano Groundwater Treatment Plant) due to the unanticipated catastrophic failure leading to an emergency shutdown on 12/5/22. It was discovered that the clearwell had experienced significant corrosion which led to structural failures of numerous roof beams, roof panels, and floor sections. The clearwell is a critical component to the entire treatment process and does not have redundancy. Treatment plant is offline and not discharging until appropriate repairs are completed. |

CSC 001D We missed an Effluent Composite sample for the week of 11/29-12/05. Analytes missed were TSS and cBOD. These analytes are to be sampled 5-days per week. The Effluent composite sampler was left in Grab sample mode over the weekend. Therefore, there was not composite sample on Monday, November 30th. The sample was rescheduled for Saturday, December 5th. Although I had scheduled the sample in Lab Cal, I simply forgot to collect it since it was outside of our normal sample routine. |
