President Joe Biden's administration denied almost all outstanding petitions from oil refiners asking to be exempted from mandates that require them to mix biofuels into their fuel.
The U.S. EPA on July 14 denied 26 petitions filed by small refineries seeking small refinery exemptions (SREs) from their RFS blending obligations for one or more of the compliance years between 2016 and 2023. Only two SRE petitions remain pending.
