Rule Summary

On September 16, 2025, EPA announced a supplemental proposed rule that takes into consideration the expected impacts of small refinery exemption decisions issued as part of the August 2025 SRE Decisions Action. Based on this information, EPA is co-proposing additional volumes representing complete (100 percent) reallocation and 50 percent reallocation for SREs granted in full or in part for 2023 and 2024, as well as those projected to be granted for 2025, as part of the ongoing RFS rulemaking. EPA is also providing more information on its projection of SREs to inform the calculation of the 2026 and 2027 percentage standards.

Public Hearing

EPA held a virtual public hearing on October 1, 2025, for the supplemental proposed rule.
