Emissions Factors Program Improvements

The purpose of this Advanced Notice of Proposed Rulemaking (ANPRM) is to convey issues raised by stakeholders about EPA's emissions factors program, inform the public of our initial ideas on how to address these issues, and solicit comments on our current thinking to resolve these issues. Our goal is to develop a self- sustaining emissions factors program that produces high quality, timely emissions factors, better indicates the precision and accuracy of emissions factors, encourages the appropriate use of emissions factors, and ultimately improves emissions quantification. Although initially developed for emissions inventory purposes only, use of emissions factors has been expanded to a variety of air pollution control activities including permitting, enforcement, modeling, control strategy development, and risk analysis. This ANPRM discusses the appropriateness of using emissions factors for these activities.
