    Type:Notice
    Citation:89 FR 99862
    Reading Time:about 22 minutes

    The Environmental Protection Agency (EPA) has released the MOVES5 model, which is used to estimate emissions from vehicles like cars, trucks, and buses. This model is crucial for creating state implementation plans (SIPs) and transportation conformity analyses, and it incorporates the latest data and regulations on emissions. While it must be used immediately in SIP development, there's a two-year grace period until December 2026 for it to become mandatory in transportation conformity analyses outside of California. The EPA provides guidance and support materials to help users transition to MOVES5, ensuring they can accurately assess vehicle emissions.

    Simple Explanation

    The EPA has created a new tool called MOVES5 to help figure out how much pollution comes from vehicles like cars and buses. People who work with this tool have two years to start using it outside of California.

    The Environmental Protection Agency (EPA) has released the MOtor Vehicle Emission Simulator model (MOVES3) for use outside of California. This is an update to the EPA's tools for estimating emissions from vehicles. MOVES3 should be used for state plans and transportation conformity, starting a two-year grace period that allows its adoption before it becomes mandatory by 2023.
