What it does
This is a Congressional Review Act resolution that would block an EPA rule setting renewable fuel blending requirements for 2026–2027 and partially waiving cellulosic biofuel mandates for 2025. If passed, the rule would be nullified and have no legal effect, leaving prior fuel standards in place.
Why we flagged it
This is a procedural CRA resolution under 5 U.S.C. § 801 et seq., which allows Congress to nullify agency rules within 60 legislative days. It does exactly one thing: disapprove a specific EPA rule. The mechanism is transparent and statutory.
What the text implies
- Disapproving the rule does not restore a prior rule—it voids the 2026–2027 standards and the partial waiver, leaving the question of what fuel standards actually apply in 2026–2027 potentially unresolved unless prior rules remain in effect by operation of law.
- The partial waiver of cellulosic biofuel requirements was a concession to fuel blenders and refiners; disapproving it tightens cellulosic mandates, raising compliance costs for fuel producers and potentially increasing fuel prices at the pump.

Who stands to gain
renewable fuel producers (ethanol, biodiesel, cellulosic biofuel manufacturers); agricultural commodity producers (corn, soybeans, cellulose feedstock suppliers)
