1. Due to a programmed power outage at the PLWTP, the composite effluent and influent samples from the 08/26/25 collection may differ from the composite sample definition stated in the ORDER NO. R9-2017-0007; NPDES NO. CA0107409 Part 2. ¿ Glossary of Common Terms ¿Daily Discharge¿. The 08/26/2025 effluent and influent composite samples were obtained from a combination of at least eight sample aliquots of at least 100 mL at periodic intervals during the time frame from 0001 to 0110 and 1300 to 2359; therefore, the samples not necessarily reflect the plant¿s operating hours over a 24-hour period for the following analyses: Floatable solids, BOD, TDS, TSS_VSS. 2. The BOD internal control standard recovery was outside of the method acceptance limits values stablished in the Current MDLs & Acceptance Criteria (Document #13584). Herby, the result values for the 8/22, 8/23 Effluent and Influent composite samples were flagged as non-reportable. Due to the nature of the BOD testing, the samples could not be reanalyzed after the 5-day incubation period when results become known. 3. Due to contamination during the batch 25219BN35 continuous liquid-liquid extraction; the Hexachlorocyclopentadiene internal control standard recovery and RPD percentages were outside of the method acceptance limits values stablished in the SOP (6144) 625.1 Revision: 11, Section 16. Herby, the result values for the 08/06 Effluent and Influent composite samples processed in were flagged as non-reportable. Additionally, the Bis(2-ethylhexyl) phthalate compound was detected in the Method Blank above the Method Detection Level; the result values for the 08/06 Influent composite sample processed in batch 25219BN35 were flagged as non-reportable. |

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. |

Deficient Reporting |
The California Regional Water Quality Board, San Diego Region (San Diego Water Board) completed a limited review of the County of San Diego?s (Enrollee?s) submitted Sewer System Management Plan (SSMP) against the requirements of sections 8.1 and 8.2 of Attachment D to State Water Resources Control Board Order WQ 2022-0103-DWQ, Statewide Waste Discharge Requirements, General Order for Sanitary Sewer Systems (General Order) and determined that the SSMP is incomplete. While the SSMP was timely uploaded to the California Integrated Water Quality System (CIWQS) database by May 2, 2025, it failed to address the following permit requirements: 8.1 System Evaluation and Condition Assessment The Plan must include procedures to: ? Evaluate the sanitary sewer system assets utilizing the best practices and technologies available; ? Identify and justify the amount (percentage) of its system for its condition to be assessed each year; ? Prioritize the condition assessment of system areas that: ? Hold a high level of environmental consequences if vulnerable to collapse, failure, blockage, capacity issues, or other system deficiencies; ? Are located in or within the vicinity of surface waters, steep terrain, high groundwater elevations, and environmentally sensitive areas; ? Are within the vicinity of a receiving water with a bacterial-related impairment on the most current Clean Water Act section 303(d) List; o Assess the system conditions using visual observations, video surveillance and/or other comparable system inspection methods; o Utilize observations/evidence of system conditions that may contribute to exiting of sewage from the system which can reasonably be expected to discharge into a water of the State; o Maintain documents and recordkeeping of system evaluation and condition assessment inspections and activities; and o Identify system assets vulnerable to direct and indirect impacts of climate change, including but not limited to: sea level rise; flooding and/or erosion due to increased storm volumes, frequency, and/or intensity; wildfires; and increased power disruptions. 8.2 Capacity Assessment and Design Criteria The Plan must include procedures to identify system components that are experiencing or contributing to spills caused by hydraulic deficiency and/or limited capacity, including procedures to identify the appropriate hydraulic capacity of key system elements for: ? Dry-weather peak flow conditions that cause or contributes to spill events; ? The appropriate design storm(s) or wet weather events that causes or contributes to spill events; ? The capacity of key system components; and ? Identify the major sources that contribute to the peak flows associated with sewer spills. The capacity assessment must consider: ? Data from existing system condition assessments, system inspections, system audits, spill history, and other available information; ? Capacity of flood-prone systems subject to increased infiltration and inflow, under normal local and regional storm conditions; ? Capacity of systems subject to increased infiltration and inflow due to larger and/or higher-intensity storm events as a result of climate change; ? Increases of erosive forces in canyons and streams near underground and above-ground system components due to larger and/or higher-intensity storm events; ? Capacity of major system elements to accommodate dry weather peak flow conditions, and updated design storm and wet weather events; and ? Necessary redundancy in pumping and storage capacities. |

The analytical batch was deemed non-reportable. Due to the nature of BOD testing, the sample could not be reanalyzed after the 5-day incubation period when results become known. Therefore, the permit BOD frequency requirements of 1/Day were not met. 2. Base Neutral analysis under EPA 625.1 results showed %RPD outside of criteria for Hexachlorocyclopentadiene. The results for effluent, effluent duplicate where all not-detected (ND). The Internal Check 1, Matrix Spike 1 and Matrix Spike duplicate were within acceptance recovery limits. Batch met accuracy but not precision criteria therefore, per QA criteria the results in SOP ID 6144 revision 10 section 16.8 and 16.9, the results for Hexachlorocyclopentadiene are not reportable. |

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. |

A monthly oil and grease sample was missed at M-001E for the reporting period. This was due to an error in sample preparation and an accidental oversight in the master schedule which cause the sample to be missed. All other samples for the month were collected as planned.

The effluent pipeline had a leak, which caused the vault to gradually fill with water. The operator on duty discovered the issue and installed a sump pump in the vault. For a couple of hours, the sump pump successfully managed to keep up with the leak. However, the leak eventually overwhelmed both the vault and the sump pump, resulting in approximately 800 to 900 gallons of water spilling into the surrounding rocks. |
