emission factors reported by NCASI depend on the sources they considered for their analysis, as reported in the next subsections. Because EPA is a member of NCASI, their reports have been made available to the public in EPA libraries. After screening the full catalog of NCASI reports available in EPA libraries, we identi- fied and reviewed three NCASI technical reports rele- vant to biomass combustion and analyzed the data on emission factors for boilers that burn unconventional
including wood products manufacturing and forest management (NCASI 2023). The technical reports and white papers published by NCASI provide a wealth of information on emission factors related to wood and forest residue combustion. NCASI reports the average emission factors based on statistical analy- sis NCASI performed using data from several boiler emission sources including EPA’s emission limits as well as stack tests conducted by boiler facilities.
