1148331 07/29/2025 Groundwater Pace Analytical reported a total coliform concentration of 49 MPN/100 mL at RGW-006, which exceeds the groundwater limitation of 2.2 MPN/100 mL. As RGW-006 is located upstream of the WWTP, the cause of the elevated total coliform result is unknown. Violation N eSMR Dunsmuir WWTP 452141 R5-2024-0009 N

1139156 12/31/2024 Deficient Monitoring 1-hour average and 4-day average Chlorine Residual: The City''s Endress Hauser unit that stores the continuous monitoring of chlorine and sulfur dioxide residuals failed to save this data beginning October 22, 2024. The City became aware of the issue on December 26, 2024. After investigating, it was determined that the SD cards that store the data were full. The City ordered replacement SD cards, and the SD cards were replaced January 17, 2025. The City feels confident there was no effluent discharged to the River that had a chlorine residual greater than 0.01 mg/L during this time. The City collected daily grab samples of the effluent, at all of their chlorine analyzers, to verify the chlorine analyzers are working accurately. If the chlorine analyzer for final effluent detects a residual greater than 0.01 mg/L, it would have closed the valve to the River immediately and sent an alarm to the on-call Operator. This valve did not close during the month of November. Before returning the effluent discharge to the River on November 3, 2024, the City did verify that the valve closes when a chlorine residual is detected at the final effluent chlorine analyzer. Some of the Electrical Conductivity measurements for RSW-001, RSW-002, and EFF-01 were taken with the City''s handheld meter, but has just been informed this is not allowed in the City''s current permit due to the City not being an ELAP certified facility for EC. Violation N eSMR Dunsmuir WWTP 452141 R5-2024-0009 Y
1139155 06/30/2024 Order Conditions On 6/4/24, the City''s monthly total nitrogen limit of 10 mg/L was exceeded with a reported value of 35.8 mg/L to the ponds. In May the plant experienced a plant upset, which we believe damaged the nitrifying biology in the plant likely resulting in this total nitrogen violation. Violation N eSMR Dunsmuir WWTP 452141 R5-2024-0009 Y
1139154 06/30/2024 Order Conditions Total Coliform Monthly Maximum limit of 240 MPN/100 mL was exceeded on 6/11/24 and 6/25/24 with a reported value of 1600 MPN/100 mL at LND-00A on both days. It is unclear why this exceedance occurred as we had a free chlorine residual of 1.2 mg/L and 1.94 mg/L in the effluent, respectively. Violation N eSMR Dunsmuir WWTP 452141 R5-2024-0009 Y
1139153 06/30/2024 Order Conditions Total Coliform 7-Day Median limit of 23 MPN/100 mL was exceeded on 6/11/24 and 6/25/24 with a reported value of 1600 MPN/100 mL at LND-00A on both days. It is unclear why this exceedance occurred as we had a free chlorine residual of 1.2 mg/L and 1.94 mg/L in the effluent, respectively. Violation N eSMR Dunsmuir WWTP 452141 R5-2024-0009 Y
