The EPA has released decisions on 34 small refinery exemption petitions from 2025, granting full or partial exemptions that total 1.76 million RINs - significantly more than initially estimated. This discrepancy has prompted the agency to announce a new rulemaking that will reallocate 100 percent of exempted volumes to 2026 and 2027 renewable volume obligations, potentially increasing compliance burdens for nonexempt obligated parties.
