01 · The brief

This joint resolution under the Congressional Review Act would disapprove and nullify an EPA rule (90 Fed.

Reg. 643, Jan 6, 2025) that granted California a waiver of preemption for its Omnibus Low NOx motor vehicle, engine, and nonroad engine pollution-control standards.

If enacted, the specified EPA decision would be declared to have no force or effect, preventing California from implementing the waived standards under that rule.

Passage35/100

Procedural advantages under the CRA increase feasibility, but high ideological salience, federalism conflict, and executive approval risk lower overall odds.

CredibilityAligned

Relative to its intended legislative type, this bill is a straightforward Congressional Review Act disapproval resolution: it clearly identifies the targeted rule and contains the standard operative language to nullify the rule. It relies on the CRA's established mechanism and does not attempt broader statutory changes.

Contention75/100
