Violation null Complaint SCWA Russian River CSD 427524 R1-2021-0002 N 1126050 03/01/2024 Order Conditions During the late evening of Friday, March 1, 2024 and into the early morning of Saturday, March 2, 2024, the District's treatment plant experienced an unauthorized discharge with an estimated volume of up to 276,078 gallons of secondary treated wastewater.

Violation N eSMR SCWA Russian River CSD 427524 R1-2021-0002 N 1121938 11/17/2023 Order Conditions On October 17 at 16:00 hours and continuing through October 18 at 06:00 hours there was a communications failure for our secondary effluent turbidity readings. All other compliance data was captured and there were no fluctuations in flow patterns outside of the normal diurnal flows. The final effluent turbidity during this same timeframe was well within the required turbidity range with an average turbidity of 0.45 NTU's and a daily maximum of 0.85 NTU's. Given these factors we believe that the secondary effluent turbidity remained in compliance.
