Foam over incident in Three Rivers

The Three Rivers Wastewater Treatment Plant reports there was a foam-over incident at 5:35 p.m. Thursday as a result of electrical maintenance.
Plant supervisor Doug Humbert said a passerby noticed foam in an area along the 400 block of Wolf Road.
The event was believed to be caused by routine electrical maintenance that required all blowers to operate during part of the day.
Humbert said the foam-control system didn’t respond quickly enough to stop the foam from exiting out the digester’s top. Approximately 300-400 gallons of partially treated bio-solids escaped the digester. He said all bio-solids were restricted to the ATAD foam containment area and that no bio-solids escaped to the storm water drains of the plant.
Humbert said staff made the required notifications to Michigan Department of Environmental Quality and the Branch-Hillsdale-St. Joseph County Health Department.
