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.

The Environmental Protection Agency (EPA) is reopening the public comment period on a proposed rule concerning air quality standards in Fairbanks North Star Borough, Alaska.

Due to requests for more time to evaluate the proposal, the EPA has extended the comment period by 30 days, until April 23, 2025. However, the EPA is not reopening the comment period for the transportation conformity adequacy process related to motor vehicle emissions budgets.

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. It includes updates like new emission rates and data from various sources, improving the accuracy of emissions estimates.
