Now more than ever, our biofuels policy must deliver certainty for American farmers, feedstock processors, biofuels producers, and consumers. We stand ready to work with you in implementing a supplemental rule which is consistent with Set 2 projections, and encourage you to ensure that DOE conducts meaningful, transparent engagement with biofuel stakeholders on any methodology change for adjudicating future SREs.

I’ll keep working with Administrator Zeldin to get this rule finalized

Fetched verbatim passage. AI summary (separate from source): In the lookback window, EPA announced a proposed revision to Set 2 volumes for additional 2025 SRE volumes and quoted Nunn saying he would keep working with the administrator to finalize it. Because the action was still a proposal with comments open, this shows effort and unresolved implementation rather than final delivery.

which include 70 percent reallocation of small refinery exemptions granted for 2023–2025.

Fetched verbatim passage. AI summary (separate from source): EPA’s final Set 2 rule established 2026 and 2027 RFS standards and included partial SRE reallocation for 2023–2025, supporting partial delivery of the core RFS rule component while leaving later 2025 SRE reallocation/methodology issues unresolved.

Assessments

Public state: pending As of 2026-10-14 · verified · . Original AI recommendation (not independently established): unresolved. same_term A for effort

The verified commitment was to work with the administration on implementing a supplemental RFS rule and encourage transparent DOE engagement. The verified evidence shows Nunn saying, "I'll keep working with Administrator Zeldin to get this rule finalized," which supports effort during the same term, but it does not prove final enactment of the supplemental rule or DOE stakeholder-engagement changes attributable to him. The final-rule passage notes 70 percent SRE reallocation, but it does not establish that the promised supplemental rule was implemented as promised or that Nunn materially caused or advanced the final outcome. With no documented expired deadline, the appropriate status is unresolved rather than never or delivered.
