Notes
This plant is an Oriented Strandboard (OSB) manufacturing facility. According to the air permt there is a small cogen boiler at the facility but it is not currently in use. The plant's primary product is OSB (treated wood), not electricity or heat.

This facility is a major source of Hazardous Air Pollutant (HAP) emissions. (Source: Air Permit)

The dryers and press are heated by a wood-fired thermal oil heater (Wellons Heat Source EU 108). The hot exhaust from the heater is passed by oil-filled tubes and the heated oil is used to heat the press and then the hot exhaust is routed to the dryers for drying wood wafers.

Line 2 dryers (including the wood-fired heater emissions) are controlled by wet electrostatic precipitators and a thermal oxidizer. Line 2 press emissions (primarily VOCs, phenol, and formaldehyde) are currently uncontrolled but will be controlled by September 2008 by thermal oxidizer. Various handling, finishing, and forming processes are also part of Line 2. The Facility also has a wood-fired cogeneration boiler but it is not operated at this time.
