1153843 03/31/2026 Deficient Monitoring The permit requires weekly monitoring of Biochemical Oxygen Demand (BOD) and Total Suspended Solids (TSS) at monitoring location REC-001 during periods of recycled water production. During the week of March 21, 2026, recycled water was produced; however, the required samples were not collected.The missed samples were the result of an oversight in routine sampling activities. Violation N eSMR Ukiah City WWTP 458153 R1-2024-0016 N
1153842 01/31/2026 Deficient Monitoring The permit requires monthly monitoring of Specific Conductance at monitoring location EFF-002. A sample was not collected during the January 2026 monitoring period. The missed sample was the result of an oversight in routine sampling activities. Violation N eSMR Ukiah City WWTP 458153 R1-2024-0016 N
1150767 12/29/2025 OEV Total Coliform Weekly Average limit is 23 MPN/100 mL and reported value was 79 MPN/100 mL at EFF-002. *** MMP Exempt Reason:No discharge to surface waters. Violation N eSMR Ukiah City WWTP 458153 R1-2024-0016 N
1148905 07/14/2025 Deficient Monitoring No coliform sample was collected on July 14th 2025 while production of Recycled Water was taking place. The cause of the sampling deficiency is not readily apparent and was most likely due to a failure to collect the sample. Violation N eSMR Ukiah City WWTP 458153 R1-2024-0016 N
1145332 07/23/2025 Deficient Monitoring The April monthly sample for EFF-002 Specific Conductance was collected by an operator who was in the process of training and the measured value for Specific Conductance that was analyzed on 4/23/25 had a result of 0.5 µS/cm. This value is not possible for wastewater and is more likely a reading of the air. The probe used for Specific Conductance is a multi-parameter probe that has pH and temperature at the tip, with a side port higher up on the probe body for Specific Conductance. It is believed that the operator did not realize that the specific conductance sensor was higher up on the probe and only inserted the pH and temperature sensors into the sample. The problem was not discovered until after the end of April. Violation N eSMR Ukiah City WWTP 458153 R1-2024-0016 N
1145331 07/01/2025 OEV Total Coliform Daily Maximum limit is 240 MPN/100 mL and reported value was 290.9 MPN/100 mL at REC-001. *** MMP Exempt Reason:Recycled Water Violation Violation N eSMR Ukiah City WWTP 458153 R1-2024-0016 N
