The MN Department of Natural Resources 2008 report states that 'operations at this plant were curtailed in 2008' The air emission units that will exist at this expanded facility will consist of four rotary wood wafer dryers, one conveyor-type wood wafer dryer, two steam generating boilers, one thermal oil heater, one board press, and seven wood waste handling operations. The rotary wood wafer dryers are controlled by simple cyclones, wet electrostatic precipitators, and a thermal oxidizer. The conveyor-type wood wafer dryer will be controlled by combusting the exhaust from Zone 1 in the thermal oil heater and by exhausting Zones 2 and 3 through a simple cyclone. The boilers are controlled by multiclones and a dry electrostatic precipitator. The thermal oil heater will be controlled by a multiclone and a dry electrostatic precipitator. The board press will be controlled by a thermal oxidizer. Wood waste handling operations will be controlled by fabric filters.
