Do you support expanding the use of ethanol-gasoline blends to help lower your costs at the pump?
Representative Eric Sorensen is pushing for permanent, nationwide authorization of E15 gasoline in the upcoming farm bill. This legislative effort aims to standardize fuel access for operators across the U.S. by removing existing EPA summer restrictions on the 15% ethanol blend.
Why it matters
Proponents argue that year-round E15 availability could lower gasoline costs by 30 cents per gallon while simultaneously boosting demand for corn. For agricultural operators, the proposed shift could drive up grain prices by 10-30 cents per bushel, potentially adding $30,000 in annual revenue for a 1,000-acre farm.
Expanded E15 usage is projected to increase annual corn demand by 2 billion bushels and raise corn prices by 10-30 cents per bushel. These shifts follow a summer in which diesel costs peaked at $7 per gallon, leaving operators to pay approximately $2,100 for a single fill-up of a 300-gallon John Deere Harvester S7 tank.
The players
Eric Sorensen
A U.S. Representative who advocates for agricultural policies and ethanol-blend fuel authorizations in the farm bill.
Environmental Protection Agency
The federal regulatory body responsible for enforcing Clean Air Act standards that limit E15 fuel availability during summer months.
The details
The current regulatory environment requires the EPA to restrict E15 sales during summer months under the Clean Air Act, except in regions like Illinois where waivers are already in place. Including E15 authorization in the farm bill would eliminate the need for annual emergency waivers, providing consistent fuel options at the pump. This move aims to standardize ethanol blends nationally to reduce pump prices by 15-20% compared to standard unleaded fuel.
Timeline
The EPA issued a nationwide E15 fuel waiver during the summer of 2026.
Representative Eric Sorensen campaigned for year-round E15 authorization on October 27, 2026.
Market Landscape
This legislative push seeks to permanently bypass Clean Air Act restrictions that have historically limited E15 fuel sales to specific regions or seasonal waivers. It marks a shift toward establishing a national standard for renewable fuel blends as a primary mechanism for managing energy costs in agriculture.
Operators should monitor the Senate’s progress on the farm bill, as its passage would secure year-round E15 availability and shift regional grain pricing. Those managing heavy machinery should also account for the potential for higher corn input costs in their financial planning if the legislation increases per-bushel prices.
The takeaway
The move to legalize E15 year-round represents a major pivot in how agricultural supply chains could influence national fuel markets. Monitor the upcoming Senate farm bill floor proceedings to gauge whether this provision remains intact before finalizing your cost-per-bushel estimates for the next harvest season.
