The Coal-Fired Heat Plant CFHP at Malmstrom Air Force Base MAFB, MT is designed to fire both natural gas and sub-bituminous coal. Under normal operating conditions, the coal-fired generators meet the Montana Department of Environmental Quality MDEQ emission standards. However, wider certain nonstandard i.e., startup, shutdown, and malfunction conditions, the plant may exceed emission limits. MAFB tasked the U.S. Army Engineer Research and Development Center, Construction Engineering Research Laboratory ERDCCERL to conduct a study to determine emission limits during startup, shutdown, malfunction, and scrubber bypass, to make appropriate recommendations to help MAFB maintain the heat plant in compliance with permit requirements at all times when fired on coal, or to recommend alternative fuels and equipment to maintain compliance. The study concluded that the MAFB CFHP can able to meet its current permit limits through equipment modifications and operational changes. A possible alternative to the operational changes would be to pursue a change to the Montana System Implementation Plan SIP andor their CFHP operating permit.
