Overview

• The House voted 231-191 and 225-196 to rescind EPA waivers allowing California to enforce stricter heavy-duty truck emission standards.
• The resolutions target California mandates for zero-emission trucks and nitrogen oxide limits, both aimed at reducing pollution and emissions.
• The Government Accountability Office determined these waivers are not subject to the Congressional Review Act, a finding ignored by House Republicans.
• Senate Republicans face a procedural dispute as the Senate parliamentarian also ruled the waivers exempt from CRA challenges.
• The Clean Air Act allows California to set stricter pollution standards with EPA approval, a policy followed by 11 other states affecting over 10% of the U.S. population.
