Data Search by General Subjects
Robert (Bob) Fraser, Senior Technical Director at AECOM Environment, discussed AECOM’s experience to date with the boiler MACT. He indicated that no one plant is now demonstrating the ability to meet all the pollutant requirements. There is very little data on CO and dioxins. It may be necessary to install back end CO and dioxin controls. These could be quite expensive. Minimizing the time at which the gas is in the 800-460 degrees F range by quenching should be effective in avoiding dioxin formation, but this is not an option where downstream fabric filters are being operated. One big question is whether a source which switches fuels to meet the MACT would then be a “new MACT source.” If a new permit is required because of fuel switching, then it is very possible that the source would be considered “new.”
