Gaps in refinery exemptions
HollyFrontier Cheyenne Refining v. Renewable Fuels Assn.
In brief
A prior gap did not automatically disqualify a small refinery from getting an exemption extension, and the Supreme Court overturned the Tenth Circuit's ruling.
- Where it stands
- Decided
Decided 6-3 · June 25, 2021 · Opinion by Justice Gorsuch
- What it’s about
- This case was about the Renewable Fuel Standard and whether small oil refineries can receive a hardship exemption from blending renewable fuels even if their exemption had lapsed in earlier years.
- Who it affects
- A small refinery that previously received a hardship exemption can still obtain an extension despite a prior gap; uninterrupted exemptions since 2011 are not required solely because of that gap.
Summary: written with AI from the case record.

What it's about
The Court held that a refinery may still obtain an "extension" of its exemption despite a prior gap in coverage.
The case interprets the Renewable Fuel Standard, which requires renewable-fuel blending while allowing some small refineries to seek relief from that requirement.
Question presented
In order to qualify for a hardship exemption under § 7545(o)(9)(B)(i) of the Renewable Fuel Standards, does a small refinery need to receive uninterrupted, continuous hardship exemptions for every year since 2011?
What the Court decided
Holding
A small refinery that previously received a hardship exemption may obtain an “extension” under §7545( o )(9)(B)(i) even if it saw a lapse in exemption coverage in a previous year. 948 F. 3d 1206, reversed.
- Result
- Reversed
The vote
From the opinions
“The statute’s text and structure direct a clear answer: EPA cannot “extend” an exemption that a refinery no longer has.”
What's next
Affected small refineries may seek extensions from the EPA despite earlier gaps, and the agency can apply the Court's interpretation when considering those requests. The ruling does not automatically grant an exemption to every small refinery.
Why it matters
The ruling does not automatically give every refinery an exemption.
