Question # 577

577. Many pulp and paper mills burn wood for on-site electricity and may trigger manufacturing thresholds when one naturally occurring compound changes to another (e.g., copper or manganese compounds change to copper or manganese oxides). Does EPA publish emissions factors for metals manufactured from the burning of trees?
Emissions Factors provided in Section 1.6 - Wood Waste Combustion in Boilers of EPA’s document AP-42, Compilation of Air Pollutant Emissions Factors can be used to calculate emissions for metal manufactured from the burning of trees. However, if a facility has better readily available information that would enable the facility to more accurately calculate the emissions generated, the facility should use that information.
