Order Conditions |
March 11, 2024 - Between 438,000 and 525,000 gallons of Secondary Treated Wastewater was discharged to the Russian River through Discharge Point 001 (EFF-001B) due to an operator error involving the set point conditions of several valves. |
The City is planning to revise its River Discharge SOPs to require supervision from a Senior Operator or higher when isolation valves are opened/closed and to include a 3-D diagram of the valve system to increase staff understanding of all connections and potential impacts. Refresher training on river discharge procedures will be held for all operations staff each year, approximately one month prior to the start of the river discharge season. In addition, two auto actuation valves will be installed as part of the Phase 4 Recycled Water Project. This installation will provide automatic closure of the River Discharge Isolation Valve when it is not being used and when off spec water is produced. The project has been designed, funded, and is currently underway. However, the lead time for receiving the valves is 48 weeks so installation will not occur until the summer of 2025 |

Total Coliform Weekly Average limit is 23 MPN/100 mL and reported value was 170 MPN/100 mL at EFF-002. |
The high coliform sampled at EFF-002 on 9/29/21, is most likely the result of an unforeseen sludge buildup at the effluent structure, due to closing the percolation pond valve for increased recycled water production. Water was only flowing to the percolation ponds from this location during the maintenance, and the effluent valve was closed again immediately following the maintenance.

Total Coliform 7-Day Median limit is 23 MPN/100 mL and reported value was 920 MPN/100 mL at EFF-002. *** MMP Exempt Reason:Discharge at EFF-002 is to a percolation pond. This is not an NPDES discharge, thus not subject to MMPs. |
The City believes there was contamination in the pump used to collect the sample at this location. In mid November we stopped using the contaminated pump, and results have been compliant since. |
