This bill would require the state board to establish the Advanced Clean Fleets Regulation Appeals Advisory Committee to review appeals of denied exemption requests, with committee members from specified governmental and nongovernmental entities. The committee must meet monthly, publicly share meeting recordings, and make recommendations on appeals within 60 days. The state board must consider these recommendations at a public meeting within 60 days. The bill also expands the emergency vehicle exemption under the regulation and modifies the daily usage exemption for state and local government fleets, prohibiting the board from requiring documentation of a zero-emissions vehicle purchase agreement for certain compliance extensions.
