## Abstract

The Environmental Protection Agency (EPA) is approving and announcing the availability of the Motor Vehicle Emissions Simulator model (MOVES2014) for official use outside of California. MOVES2014 is the latest state-of-the art upgrade to EPA's modeling tools for estimating emissions from cars, trucks, buses, and motorcycles, based on the latest data and regulations. MOVES2014 is approved for use in state implementation plans (SIPs) and transportation conformity analyses outside of California. This notice starts a two-year grace period before the MOVES2014 emission model is required to be used in new regional emissions analyses and new hot-spot analyses for transportation conformity determinations outside of California.
