U.S. Refinery-State Senators Move to Block Trump’s Renewable Fuel Shift

A group of refinery-state lawmakers, led by Senator Mike Lee (R-Utah), is pushing legislation to stop President Donald Trump from shifting renewable fuel blending obligations from small refineries to larger ones. The draft bill, Protect Consumers from Reallocation Costs Act of 2025, would amend the Clean Air Act to bar the Environmental Protection Agency (EPA) from reallocating blending requirements, a proposal currently under White House review.

The fight underscores the deep divide between the U.S. oil industry and farm interests that depend on ethanol and other biofuels. At issue is whether larger refineries should cover obligations waived for small refineries through long-standing federal exemptions. “Punishing American energy producers who comply with the EPA’s made-up rules isn’t just unfair, it’s bad for everyday consumers,” Lee said, warning it would raise fuel prices and hurt Utah’s refineries.

The EPA recently cleared a backlog of more than 170 small refinery exemption requests dating back to 2016, forcing a review of how billions of gallons of exempted biofuel requirements will be addressed. A White House decision is expected in the coming weeks, as GOP divisions over the policy complicate Trump’s efforts to unite Republicans and avert a government shutdown.

The Renewable Fuel Standard exemption question sits at the intersection of biofuel-industry, refinery-industry and agricultural interests. Small-refinery exemptions have historically waived RFS blending requirements for facilities meeting specific criteria; the question of whether larger refineries should cover the exempted volumes creates a zero-sum political dynamic between refining and ethanol/biofuel constituencies.

The 170-request backlog resolution shifts the practical scale of the question materially. Whether the eventual EPA position reallocates the exempted volumes or lets them lapse will directly affect biofuel producer revenues and refinery compliance costs - both meaningful business-planning variables.
