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. City did not collect hardness samples for RSW-001 and RSW-002.

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 1145909 06/30/2025 Order Conditions The City exceeded the land total nitrogen average monthly discharge specification of 10 mg/L with a result of 23.6 mg/L. Violation N eSMR Dunsmuir WWTP 452141 R5-2024-0009 N 1141818 02/28/2025 Deficient Monitoring During the month of February, the City analyzed the EC data in-house. Due to the misinterpretation of the permit, the City did not report any EC data for the following: Violation N eSMR Dunsmuir WWTP 452141 R5-2024-0009 N 1142841 02/26/2025 Groundwater Both RGW-006 and RGW-010 exceeded the total coliform groundwater limit of 2.2 MPN/100mL with results of 17 MPN/100mL and 12 MPN/100mL, respectively. Violation N eSMR Dunsmuir WWTP 452141 R5-2024-0009 N 1145441 06/30/2025 Deficient Monitoring The City analyzed EC data in-house instead of sending to a certified lab. Total Trihalomethanes was intended to be sampled with the quarterly sampling, but there was a communication error between the lab and City not being notified there was a sampling error. The EFF-001 DOC sample was missed prior to pulling out of the River. Violation N eSMR Dunsmuir WWTP 452141 R5-2024-0009 N 1147604 08/05/2025 Order Conditions The City exceeded the land total nitrogen average monthly discharge specification of 10 mg/L with a result of 13.6 mg/L.  Violation N eSMR Dunsmuir WWTP 452141 R5-2024-0009 N 1141273 01/21/2025 OEV Total Coliform 7-Day Median limit is 23 MPN/100 mL and reported value was 33 MPN/100 mL at EFF-001. Violation N eSMR Dunsmuir WWTP 452141 R5-2024-0009 N 1145910 06/30/2025 Deficient Monitoring City only collected one of the two required effluent electrical conductivity samples. Violation N eSMR Dunsmuir WWTP 452141 R5-2024-0009 N 1141272 01/31/2025 Deficient Monitoring Electrical conductivity data was not reported for the month of January for EFF-001, RSW-001, or RSW-002 as the City only collected in-house samples of EC data. This was due to a misinterpretation of the permit and what analysis can be completed in-house verse certified laboratory. Violation N eSMR Dunsmuir WWTP 452141 R5-2024-0009 N 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.
