A joint resolution providing for congressional disapproval under chapter 8 of title 5, United States Code, of the rule submitted by the Environmental Protection Agency relating to "California State Motor Vehicle and Engine Pollution Control Standards; Heavy-Duty Vehicle and Engine Emission Warranty and Maintenance Provisions; Advanced Clean Trucks; Zero Emission Airport Shuttle; Zero-Emission Power Train Certification; Waiver of Preemption; Notice of Decision".
Latest action. Read twice and referred to the Committee on Environment and Public Works.
This joint resolution nullifies the Environmental Protection Agency notice titled California State Motor Vehicle and Engine Pollution Control Standards; Heavy-Duty Vehicle and Engine Emission Warranty and Maintenance Provisions; Advanced Clean Trucks; Zero Emission Airport Shuttle; Zero-Emission Power Train Certification; Waiver of Preemption; Notice of Decision (88 Fed. Reg. 20688) and published on April 6, 2023. Among other elements, the notice grants the California Air Resources Board request for a waiver several of its regulations, including the Heavy-Duty Vehicle and Engine Emission Warranty Regulations and Maintenance Provisions. (Under the Clean Air Act, California may seek waivers of the preemption prohibiting states from enacting certain emission standards.)

Where is it in the process, and what happens next?
4 steps remain before this joint resolution could become law.
The record's latest action, on April 4, 2025: Read twice and referred to the Committee on Environment and Public Works.
- Clearing the committees it was referred to, and being scheduled for a floor vote
- Passage by the Senate
- Passage by the House
- The President's signature. If the President vetoes it, two-thirds of both chambers must vote to override.
What is a joint resolution, exactly?
A joint resolution travels the same road as a bill: both chambers pass it and the President signs it, and it then has the same force as any other law. The label is largely a matter of custom, often used for narrow or time-limited measures.
One exception matters. A joint resolution proposing an amendment to the Constitution is not sent to the President at all. It goes to the states, and three quarters of them have to ratify it.
How likely is it to become law?
Civibrief does not forecast outcomes and this page has no opinion about this one. What the record supports is a base rate, which is a fact about the whole pile, not a prediction about this measure.
In the 118th Congress (2023-24), 274 of the 16,565 bills and joint resolutions introduced became law, about 1.7 percent. That count covers every measure at every stage, including the many that never left committee.
This one is not there yet: 4 steps are still outstanding, listed above.
Has anyone actually voted on it?
No. No roll call in this Congress cites this measure. That is the ordinary outcome: most measures never reach a recorded floor vote, and a committee ends most of them simply by not acting.
A vote is not the only thing that happens to a measure. Hearings, markups, and referrals are all recorded actions, and none of them is a vote of the full chamber.
Who is behind it?
Deb Fischer (R-NE) introduced it on April 4, 2025, and 21 members have since signed on as cosponsors.
They are 21 Republicans.
Cosponsoring is a formal signature on the text. It is not a commitment to vote for the measure, it does not bind anyone's party, and a long list of cosponsors is a measure of attention rather than of prospects.
How long has it been in play?
It was introduced on April 4, 2025, 524 days ago. The most recent recorded action was 524 days ago, on April 4, 2025.
Measures do not carry over. Anything the 119th Congress has not finished by January 3, 2027 dies when the term ends, and has to be introduced again from the start in the next Congress.
Every answer above is assembled from this measure's own record on Congress.gov and from published counts of what Congress has passed before. Civibrief does not predict outcomes and takes no position on any measure.
