Summary: S.J. Res. 55 — Congressional disapproval of NHTSA rule on hydrogen vehicle fuel/storage system integrity

Status
- Introduced in Senate: May 19, 2025 (Sponsor: Sen. Shelley Moore Capito).

- Passed Senate: May 21, 2025, 51–46.

- Received in House / Held at desk: May 26, 2025.

- Official rule targeted: 90 Fed. Reg. 6218 (Jan. 17, 2025) — NHTSA “Federal Motor Vehicle Safety Standards; Fuel System Integrity of Hydrogen Vehicles; Compressed Hydrogen Storage System Integrity; Incorporation by Reference.”

Purpose and intent
- The joint resolution would use the Congressional Review Act (CRA) to disapprove and nullify a final NHTSA rule on fuel system integrity of hydrogen vehicles and compressed hydrogen storage system integrity (including any standards incorporated by reference).
- Intent: to prevent that NHTSA rule from taking effect and to block the agency from reissuing the same rule in substantially the same form absent a new law from Congress.

Key provision
- One operative sentence: “Congress disapproves the rule … (90 Fed. Reg. 6218 (January 17, 2025)), and such rule shall have no force or effect.” If enacted, the rule would be invalidated nationwide.

Who would be affected
- Federal agency: NHTSA — the agency’s published rule would be nullified and its ability to reissue a substantially similar rule would be constrained under the CRA.
- Industry stakeholders: automakers and suppliers of hydrogen fuel cell vehicles and compressed hydrogen storage systems, testing labs, and standards bodies whose incorporated standards may have been referenced by NHTSA.
- Consumers and safety advocates: potential impacts to near‑term vehicle safety requirements for hydrogen vehicles (e.g., crash, leak, and storage-system integrity testing and design requirements).
- State regulators and infrastructure planners: potential regulatory uncertainty for hydrogen‑fuel infrastructure and vehicle deployment if federal safety standards are removed or delayed.

Procedural notes and implications
- The resolution proceeded under CRA procedures; the Senate discharged the Commerce Committee pursuant to 5 U.S.C. 802(c).
- Several points-of-order and procedural votes in the Senate addressed whether CRA expedited procedures and points of order were in order; rulings and roll‑call votes (Record Votes 264–275) reflect contested procedural questions used to bring the resolution to a floor vote.
- If the House passes the resolution and the President signs it (or Congress overrides a veto), the NHTSA rule would be void and the CRA generally bars the agency from issuing a “substantially the same” rule unless Congress authorizes it by subsequent legislation.

Potential impact (high level)
- Short term: would eliminate the specific NHTSA safety rule and create regulatory uncertainty for manufacturers and safety testing related to hydrogen vehicles.
- Medium/long term: could delay adoption of uniform federal standards for hydrogen vehicle fuel and storage system integrity, affecting industry planning, consumer confidence, and state/federal safety alignment.
