Federal environmental officials say the city of Bonners Ferry has agreed to pay a $12,300 penalty for alleged violations of clean water rules caused by discharges from its water treatment plant.
The Environmental Protection Agency identified more than 1,600 permit violations at the plant between June 2005 and May 2010. The infractions included exceeding discharge limits for E. coli, biochemical oxygen demand, the amount of total suspended solids and residual chlorine.
The treatment plant serves nearly 2,600 people and is part of a system that receives domestic wastewater from residential and commercial sources. Treated water from the plant is discharged into the Kootenai River.
To remedy the problems, plant officials have reduced inflow and infiltration into the collection system and removed sludge buildup collected in sewage lagoons.
