MOVES2014b Release

EPA has released MOVES2014b to improve estimates of emissions from nonroad mobile sources. MOVES2014b does not significantly change the on-road criteria pollutant emissions results of MOVES2014 and is not considered a new model for State Implementation Plan (SIP) and transportation conformity purposes. 

The MOVES web page, www.epa.gov/moves/latest-version-motor-vehicle-emission-simulator-moves , has been updated with a detailed “Question and Answer” document, updated technical guidance, installation instructions, and an update to the MOVES2014 User Interface Reference Manual.  These materials are designed to answer user questions about the changes in nonroad emission estimates, and when and how to use the updated model.  EPA plans to announce a public webinar about MOVES2014b soon.  Individual user questions should be addressed to [email protected]
