- EPA granted full exemptions to 18 small refineries and partial exemptions to 11, covering 1.76 billion RINs’ worth of 2025 obligations.
- The 2025 RFS compliance reporting deadline moves from September 1 to October 1, 2026, for all obligated parties.
- A planned proposal to address the unprojected exempted volume in the 2026–2027 standards is not final and does not change fuel specifications or rack procedures today.

The Environmental Protection Agency has moved the 2025 RFS deadline to October 1 after granting full or partial small-refinery exemptions covering 1.76 billion Renewable Identification Numbers’ worth of obligations, giving refiners and fuel importers another month to reconcile their compliance positions.
The August 31 actions affect the credit-and-reporting side of the Renewable Fuel Standard. For blenders, petroleum terminals, and fuel haulers, the immediate consequence is commercial rather than physical: RIN availability and blending economics can change, but the EPA did not revise gasoline or diesel specifications, loading-rack procedures, shipping documents, or delivery rules.
EPA acted on 34 petitions from 34 refineries for the 2025 compliance year after consulting with the Department of Energy. The agency’s August 31 announcement says the exemptions cover 29 refineries and 1.76 billion RINs.
EPA Grants 29 Full or Partial Small-Refinery Exemptions
The decisions include 18 full exemptions, 11 partial exemptions, 3 denials, and 2 findings that the refinery was ineligible. EPA describes the decisions as final agency actions. It also reissued one partial exemption for the 2024 compliance year, a separate action that is not part of the 34-petition 2025 count.
| EPA determination | Refineries | 2025 RFS treatment |
|---|---|---|
| Full exemption | 18 | 100% of the refinery’s eligible 2025 obligation exempted |
| Partial exemption | 11 | 50% of the refinery’s eligible 2025 obligation exempted |
| Denied | 3 | No exemption granted |
| Ineligible | 2 | Refinery was found ineligible for a small-refinery exemption |
| Total 2025 petitions | 34 | 1.76 billion RINs’ worth of obligations exempted across the full and partial grants |
The 1.76 billion figure should not be read as 1.76 billion newly minted credits. EPA’s decision document says an exemption is self-implementing when a refinery has not yet demonstrated compliance. If a refinery has already retired RINs, the EPA will reverse the applicable retirement and return the RINs in proportion to the exemption.
For other market participants, the practical signal is that more RINs may remain available for compliance or trading than anticipated. EPA says its final 2026–2027 standards assumed 990 million RINs of 2025 small-refinery exemptions. The new decisions exceed that projection, and the agency plans to propose, before the end of October, reallocating 100% of the difference to the 2026 and 2027 Renewable Volume Obligations.

That future reallocation is not final. It would also be distinct from the 70% exemption reallocation already examined in Tank Transport’s 2026–2027 renewable fuel standards analysis.
October 1 Changes Compliance Timing, Not Fuel Specifications
EPA’s signed final-rule package changes the annual reporting date from September 1 to October 1 for all obligated parties, not only for refineries receiving exemptions. The agency said the extra month allows the RIN market and compliance teams to account for the late exemption decisions before reports are filed and credits are retired.
Affected small refineries must use the RFS0304 annual compliance report to identify exempted gasoline and diesel volumes separately from obligated volumes. Full-exemption recipients report no obligated 2025 gallons; partial-exemption recipients remain responsible for half of their otherwise applicable obligation.
As of September 1, EPA had posted the signed prepublication rule. Its text makes the extension operational for Clean Air Act purposes as of September 1, while the formal effective date will be the date of publication in the Federal Register. The 2025 attest engagement deadline remains June 1, 2027, and the 2026 compliance reporting deadline remains March 31, 2027.
This is not another fuel-specification waiver. Unlike the recent winter gasoline transition action, the RFS rule does not change which product a terminal may load or what a carrier may deliver. It changes when obligated parties must submit their 2025 compliance reports and complete the associated RIN accounting.
RIN Supply Could Shift Blending Economics

RIN values matter because refiners and gasoline or diesel importers can comply by blending qualifying renewable fuel or acquiring credits. The Energy Information Administration reported in June that elevated 2026 RIN prices were supporting ethanol, biodiesel, and renewable diesel blending margins.
Additional available RINs can alter those margins and the procurement decisions of refiners, marketers, and blenders. That makes credit pricing, supplier offers, and future renewable-fuel nominations relevant to petroleum terminals and the carriers serving them. Tank Transport’s renewable diesel mandate analysis explains why RIN values are only one part of the terminal and blending equation.
The exemption total cannot be translated directly into gallons or tanker loads. One gallon of ethanol generally generates one RIN, while biodiesel and renewable diesel can generate more than one. Physical demand also depends on fuel prices, contracts, state programs, available capacity, and EPA’s still-pending reallocation proposal.
Nor does the action establish lower pump prices. A Government Accountability Office review found unresolved questions about RIN cost recovery and market pass-through. The near-term evidence is a compliance-market change—not evidence of lower rack prices, reduced renewable-fuel movement, or changed tank-truck demand.
2025 RFS Deadline and Exemption Key Developments
- Exempted volume: EPA exempted 1.76 billion RINs’ worth of 2025 obligations across 18 full and 11 partial exemptions.
- New deadline: All obligated parties now have until October 1, 2026, to submit 2025 RFS compliance reports.
- Unchanged dates: The June 1, 2027, attest deadline and March 31, 2027, deadline for 2026 compliance remain in place.
- Future rulemaking: EPA plans to propose 100% reallocation of the difference between projected and actual 2025 exempted volumes into the 2026–2027 obligations.
- Operating limit: No current fuel specification, terminal loading procedure, or tank-truck requirement changed with these RFS actions.
