• Revokes California Air Resources Board authority to enforce the ACC II regulations, which mandate stricter vehicle emission and zero-emission vehicle standards than federal requirements.
• Restores federal preemption of state-level vehicle emission standards, preventing California from setting its own stricter pollution control rules.
