What This Bill Would Do
This initiates a congressional disapproval process to overturn an Environmental Protection Agency (EPA) decision that granted California a waiver to enforce its own strict emission standards for heavy-duty vehicles. If passed, the resolution would nullify the EPA's waiver, effectively preventing California from implementing its Advanced Clean Trucks and zero-emission vehicle requirements.
The resolution challenges the legal authority of California to set independent, more stringent pollution standards for heavy-duty engines, which impacts manufacturers, logistics companies, and state-level environmental policy across the U.S.
Who It Would Affect
Groups the bill's text would affect if enacted, as described in the record. Being affected is not a position for or against it.
California Air Resources Board
The board's ability to enforce its Advanced Clean Trucks and zero-emission standards depends on the EPA waiver that this resolution seeks to overturn.
Heavy-duty vehicle manufacturers
These companies must comply with California's specific emission and warranty standards if the waiver remains in effect.
