A coalition of US farm and biofuel groups, including the Renewable Fuels Association, Growth Energy and the National Farmers Union, has urged President Trump to reject a proposed expansion of small refinery exemptions (SREs) from the country's biofuel blending requirements. The administration is considering roughly doubling the volume of exemptions, from about 950 million credits to as many as 1.8 billion, with a decision expected before the end of August.
What Small Refinery Exemptions Actually Do
Under the Renewable Fuel Standard, refiners and fuel importers must blend specified volumes of renewable fuel such as ethanol and biodiesel into the US fuel supply, or purchase Renewable Identification Numbers (RINs) to demonstrate compliance. SREs let certain smaller refineries avoid some or all of that obligation if they can show disproportionate economic hardship. When granted, the exempted gallons are effectively removed from the market unless the obligation is later reallocated elsewhere, meaning a large increase in exemptions directly reduces the volume of biofuel refiners are required to blend nationally.
The Administration's Stated Rationale
According to people familiar with the matter, officials want to ease gasoline prices that have risen during the conflict with Iran, in a political environment where Republicans are seeking to retain control of Congress in November's midterm elections. The White House deferred questions to the EPA, which did not immediately respond to requests for comment reported at the time of the story.
The Coalition's Central Argument
In a letter to Trump, the farm and biofuel groups argued the administration should keep 2025 compliance year exemptions in line with the volumes the EPA itself assumed when setting the 2026 and 2027 renewable volume obligations in its March rule. They warned that granting exemptions well above those assumed levels would "decimate the demand signal" the EPA's own rule created, and that the consequences would be severe and immediate, potentially causing biofuel markets to collapse and further weakening rural economies dependent on corn and soybean oil demand.
A Republican Senator's Break From the Administration
Iowa Senator Joni Ernst, a Republican, publicly criticized the proposal, calling it "a handout to Big Oil falsely marketed as relief at the pump," and arguing that removing American-made biofuel from the market would not lower gas prices while directly harming demand for corn and soybeans that farmers in her state depend on. Her position illustrates that this dispute does not divide cleanly along party lines; it instead separates farm-state and biofuel-producing interests from oil-refining interests, regardless of political affiliation.
Why Markets Are Already Reacting
RIN prices have already fallen sharply as traders anticipate weaker biofuel demand under a larger exemption program, meaning the policy's market effects are being priced in ahead of any final decision. Oil refiners and farm groups have long disagreed over whether consumers ultimately pay more when RIN prices rise, a separate, longstanding economic dispute underlying this specific policy fight.
What Remains Undecided
No final decision on the scope of 2025 compliance year exemptions had been announced at time of writing, with a decision expected before the end of August 2026.
