Unauthorized Discharge |
the Pioneer Reservoir on 04 February 2025. The lapse sodium bisulfite dosing likely resulted in a discharge of treated wastewater with residual chlorine above the effluent limitations identified in the WDRs. The Discharger estimated that elevated levels of residual chlorine were discharged for approximately four minutes at the beginning of the discharge event. |

Surface Water |
During Event #3, the turbidity increased from the upstream receiving water location (RSW-001; Delta King 29.1 NTU) to the downstream receiving water location (RSW-002; Miller Park 51.3 NTU) by greater than 20%, The turbidity decreased from the upstream receiving water location (RSW-003; Westin Boat Dock 40.5 NTU) to the downstream receiving water location (RSW-004; Zacharias Park 24.9 NTU), meeting receiving water limitations. It¿s important to note that RSW-004 (24.9 NTU), the furthest downstream, received water was lower than RSW-001 (29.1 NTU), further indicating that the CSS is not contributing to increased turbidity in the Sacramento River during CSO events. During CSO events in the past, receiving water limitations for turbidity have occasionally been exceeded. Previous evaluations have determined that turbidity can vary in the Sacramento River over the course of storm events, but the variability was not necessarily related to CSO events. Additionally, during prior turbidity self-reported violations, the Central Valley Regional Water Quality Control Board (CVRQCB) noted that the CSS was not the only contributor to turbidity during the event, and the Notice of Violation was reversed. |

Deficient Reporting |
The Discharger stated a valid monthly biochemical oxygen demand (BOD) result was not reported in August 2024 due a laboratory error during sample analysis. There was no time to collect a repeat sample because the original monthly sample was collected on 30 August 2024. The Discharger stated that weekly dissolved oxygen (DO), pH, and temperature monitoring were not conducted during the weeks ending 21 September 2024 and 28 September 2024 due to the transfer of ownership of the Facility and the lack of qualified staff available to perform weekly monitoring. |

The in-house ammonia analysis is just for process control and was not conducted by an approved test procedure under the WDRs, so this value has not been reported to CIWQS or used to determine compliance with the monthly effluent limitations. |

The Discharger stated the missed total coliform monitoring on 09 August 2024 was due to a power outage that began before the Facility?s laboratory staff arrived in the morning and ended after laboratory staff left for the day. No disinfected effluent/recycled water was available at monitoring location UVS-002 while staff qualified to collect a sample was onsite. Total coliform monitoring results on the day prior to, and after the power loss were within the effluent limitations contained in WDRs. |

The Discharger violated the UV system operating specification for UV dose contained in the WDRs/NOA. The Discharger stated that they lowered the target dose to 80 mJ/cm2 according to new MBR process guidelines rather than maintaining permit requirement of 100 mJ/cm2. The Discharger increased the target dose back to 105 mJ/cm2 when they realized the permit limit had not been amended. After returning to the higher target dose, the Discharger noted average dose was still dipping below the setpoint and identified several UVI sensors that were causing the dose to be calculated artificially low. The Discharger replaced the faulty sensors in July 2024 and UVI dose calculations are now above the 100 mJ/cm2 permit requirement. |

Order Conditions |
The Discharger violated the Filtration System Operating Specifications for turbidity contained in the WDRs, as shown in Table C. The Discharger reported exceedances of the maximum daily average value of 2 Nephelometric Turbidity Units (NTU) on seven days in late-April 2024. The Discharger suspects the increased turbidity was caused by the seasonal change in temperature and consequent effect on the Facility¿s biological treatment process. Turbidity was restored to levels compliant with the WDRs on 26 April 2024. |

The plant was experiencing high turbidity and the plant was put on diversion for most of the day. The pH and temperature were not measured during the approximate 40-minute window when the laboratory analyst was present due to a misunderstanding. The laboratory analyst thought that the plant was going to be discharging the rest of the day but the turbidity was high that the plant operator on site had to put the plant on diversion into the following morning. |

Unauthorized Discharge |
On March 24th, 2022 the UC Davis WWTP discharged non-disinfected treated effluent for approximately 1 hour and 19 minutes, from 00:29 to 01 :48. The discharge violation occurred due to a programming error in the new UV system. Channel #2, which was not in service, had an alarm interconnect to Channel #1, which was in service, that turned off the operational banks on Channel #1, causing non-disinfected water to be discharged. |

The discharge violated the receiving water limitation for temperature contained in the WDRs. The temperature at RSW-001U was measured at 11.1*C (52.0*F) and RSW-002D was measured at 14.8*C (58.6*F). The maximum receiving water temperature difference allowed by the WDRs is 5*F. The Discharger indicated the receiving water temperature exceedance at RSW-002D occurred because of low flow conditions and recent snow melt causing the RSW-001U temperature to be much lower than the effluent-dominated temperature at RSW-002D. |

Acute Toxicity - The Discharger indicated that quarterly acute toxicity testing is typically coordinated concurrently with routine quarterly toxicity testing. However, there was an oversight in scheduling acute toxicity testing during Fourth Quarter 2021 due to the Toxicity Reduction Evaluation (TRE) monitoring schedule. The Discharger is implementing additional scheduling protocols to prevent similar occurrences in the future |

The discharge violated the receiving water limitation for temperature contained in the WDRs. The temperature at RSW-001U was measured at 4.5*C (40*F) and RSW-002D was measured at 8.1*C (47*F). The maximum receiving water temperature difference allowed by the WDRs is 5*F. The Discharger indicated the receiving water temperature exceedance at RSW-002D occurred because of low flow conditions and recent snow melt causing the RSW-001U temperature to be much lower than the effluent-dominated temperature at RSW-002D. |

Pretreatment |
The City of Davis has determined one violation regarding required independent sampling on Significant Industrial User, Yolo County Central Landfill. The City of Davis did not independently sample YCCL during the 2020 calendar year. The industrial user began discharging on January 17, 2020. On March 19, 2020 Mayor Gavin Newsom issued a statewide stay at home order. This order changed the ability to go onsite to conduct sampling. The SIU continued to discharge until May 12, 2020. It was our hope that the pandemic would subside and the SIU would begin discharging again in 2020, but the SIU did not discharge again during the 2020 calendar year, causing the City of Davis to miss the required Independent sampling. |
