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.

1126367 03/30/2024 Deficient Reporting The Annual Progress Report was due on 2/28/2024 as part of the Compliance Schedule for Final Effluent Limitations for Chronic Toxicity. Due to staff changes and oversight of this reporting requirement, the University requested an extension on 2/16/2024 so that a thorough and useful update could be provided. At the time of the request, University staff were working with sewer system dischargers to understand the cause of past intermittant toxicity. Violation N eSMR UC Davis Main WWTP 442761 R5-2021-0007 N
1132968 08/14/2024 Deficient Monitoring Effluent ammonia sampling was not completed at the weekly frequency specified by the MRP condition IV.A.1. No sample was collected for the week of August 11th. Staff missed this bottle when collecting samples for the subcontract lab. UC Davis staff did conduct in-house sampling via the HACH TNT method on 8/14/2023 and the result was 0.433 mg/L. 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. Violation N eSMR UC Davis Main WWTP 442761 R5-2021-0007 N
1136555 10/19/2024 CAT1 Biochemical Oxygen Demand (BOD) (5-day @ 20 Deg. C) Weekly Average limit is 15 mg/L and reported value was 16 mg/L at EFF-001. Violation N eSMR UC Davis Main WWTP 442761 R5-2021-0007 N
1135048 09/11/2024 Deficient Monitoring a. The MRP condition IV.A.2.i. requires that ¿effluent samples for temperature, pH, hardness, dissolved oxygen, and dissolved organic carbon shall be taken approximately the same time and on the same date with the receiving water samples for these parameters.¿ The sample for effluent dissolved oxygen was missed when all other listed parameters were collected on 9/11/2024 at both the effluent and receiving water monitoring locations. The issue was not immediately identified, and the effluent DO sampling did not occur until 9/18/2024. Violation N eSMR UC Davis Main WWTP 442761 R5-2021-0007 N
1132969 08/07/2024 Deficient Monitoring Effluent Dissolved Oxygen monitoring was conducted on a different day than the monthly effluent and receiving water monitoring. MRP condition IV.A.2.i. states that ¿the effluent samples for temperature, pH, hardness, dissolved oxygen, and dissolved organic carbon shall be taken approximately the same time and on the same date with the receiving water samples for these parameters.¿ Effluent DO was missed during sample collection on 8/7/2024, and was instead collected on 8/8/2024. Violation N eSMR UC Davis Main WWTP 442761 R5-2021-0007 N
1138442 11/22/2024 Surface Water Receiving Water Violation: During Event #1, the turbidity increased from the upstream receiving water location (16.3 NTU, RSW-001; Delta King) to the downstream receiving water location (31.4 NTU, RSW-002; Miller Park) by greater than 20%, exceeding the receiving water limitations. 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.

1139425 12/16/2024 Order Conditions Turbidity exceeded 0.2 NTU for 98 minutes on 12/16 where the limit is no greater than 0.2 NTU for 5% of the day. We also exceeded 0.2 NTU for 5% of the day on 12/21, 12/22 and 12/23. Most of our turbidity spike correlate with MBR startup which we believe is fine air bubbles trapped in the system.

1132884 08/09/2024 Deficient Monitoring 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.
