1141696 02/04/2025 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.

1131104 06/30/2024 Order Conditions 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. Violation N Report Mountain House WWTP 453528 R5-2023-0033 Y

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.

1086307 12/31/2020 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.
