House GOP Eyes Post-Passage Strategy to Pair E15 Fix with Farm Bill 2.0
Budget scoring and procedural maneuvering complicate ethanol push despite broad farm-state support
House Republicans appear to be coalescing around a strategy to advance year-round E15 gasoline sales alongside — but not directly inside — the Farm Bill 2.0 package, reflecting both political priorities and procedural constraints tied to budget scoring. The approach under consideration would allow the House to first pass the farm bill and then merge it with separate E15 legislation before sending a combined package to the Senate, a sequencing tactic often used to preserve fragile coalitions while still delivering on key policy commitments.
The E15 provision itself is largely embodied in the Nationwide Consumer and Fuel Retailer Choice Act of 2025 (HR 1346), which would amend the Clean Air Act to remove Reid Vapor Pressure restrictions that currently limit summer sales of gasoline blended with 10 to 15% ethanol. That policy has long been a priority for Midwestern lawmakers and the ethanol industry, and House GOP leadership had been promising action on the issue for months as part of the broader farm bill effort.

Meanwhile, the legislative path has become more complicated due to budgetary constraints. An amendment from Rep. Michelle Fischbach (R-Minn.) to include similar E15 language directly in the farm bill ran into resistance after the Congressional Budget Office determined it would increase the federal deficit by billions of dollars over the 10-year budget window. That finding forced leadership to reconsider how to advance the policy without jeopardizing the broader bill’s fiscal compliance.
The House Rules Committee’s decision to add a separate E15 measure to its agenda signals an effort to sidestep those constraints while keeping the policy in play. By handling the ethanol provision outside the core farm bill text, leadership can avoid immediate scoring conflicts during floor consideration and revisit integration later in the legislative process, either through a manager’s amendment, a combined package before transmission to the Senate, or during bicameral negotiations.
The CBO’s multibillion-dollar score, while initially surprising for what appears to be a regulatory change, reflects indirect fiscal effects rather than direct spending. Expanding nationwide access to E15 is expected to alter fuel consumption patterns because ethanol contains less energy per gallon than conventional gasoline, a dynamic that can reduce federal fuel tax revenues flowing into the Highway Trust Fund over time. Additional modeling likely captures shifts in Renewable Fuel Standard compliance markets and secondary impacts on agricultural programs tied to corn demand, all of which contribute to the overall budget estimate.
Taken together, the emerging strategy underscores how a relatively narrow fuel policy has become entangled in broader fiscal and legislative dynamics. While House Republicans appear intent on ultimately pairing E15 expansion with Farm Bill 2.0, the success of that effort will hinge not only on internal alignment but also on how the Senate weighs the budgetary implications and policy trade-offs associated with the ethanol provision.
