Fuel STAR Act of 2026
Sponsored By: Representative Arrington, Jodey C. [R-TX-19]
Introduced
Summary
This bill would impose a hard cap on the volume of non-advanced renewable fuel under the Renewable Fuel Standard and reshape credit rules, small refinery relief, and E15 vapor pressure limits. It ties that cap to the Energy Information Administration’s projected domestic consumption of ethanol-blended fuel and changes how compliance credits and exemptions work.

Bill Overview
Analyzed Economic Effects
4 provisions identified: 1 benefits, 0 costs, 3 mixed.
Changes to renewable fuel credit rules
If enacted, the bill would let RIN credits made in 2020, 2021, or 2022 be used to show compliance for any of the five calendar years after enactment. In each year, no more than 20 percent of the credits you use to show compliance could be from 2020–2022. The bill would also stop EPA from imposing a required electric‑vehicle credit called an "e‑RIN" when writing certain RFS rules.
Limit on non-advanced ethanol mandates
If enacted, the bill would cap the yearly required amount of renewable fuel that is not an advanced biofuel. The cap would equal the Energy Information Administration's projected annual U.S. consumption of ethanol‑blended fuel for the applicable year in the latest Annual Energy Outlook. The cap would start in the first calendar year after enactment and apply each year after.
Allow year-round 10–15% ethanol fuel
If enacted, the bill would tell EPA to apply the same Reid vapor pressure limit to gasoline blends that contain 10 to 15 percent ethanol as now applies to 10 percent blends. It would change statutory text so references to "10 percent" read "10 to 15 percent." This would let 10–15% ethanol blends be treated the same and help enable year‑round sales of E15 at the pump.
Expanded small refinery exemption rules
If enacted, the bill would expand who can seek a small refinery RFS exemption to refineries that began production on or after January 1, 2007 and average no more than 10,000 barrels per day. One year after enactment of the Farm, Food, and National Security Act of 2026, EPA would use five listed economic factors to evaluate petitions. DOE would provide two indexes and EPA must grant a petition if either index is at least 1. If EPA does not give a legal basis for denying a petition within 90 days, the petition would be treated as granted. The bill also limits total exemptions under one holding company to 75,000 barrels per day or 50% of that holding company's small refinery output, whichever is greater, and bars reallocating an exempted refinery's obligation to other refineries.
