01 · The brief

This joint resolution uses the Congressional Review Act to disapprove an EPA rule that granted California a waiver and addressed heavy-duty vehicle emission warranty and maintenance provisions, Advanced Clean Trucks, zero-emission airport shuttles, and related certifications.

If enacted, the resolution would nullify the specified EPA rule (88 Fed.

Reg. 20688 (April 6, 2023)).
