970 F.3d 392
D.C. Cir.2020Background
- The Renewable Fuel Standard (RFS) requires EPA to allocate Renewable Identification Numbers (RINs) and set standards for cellulosic biofuel; cellulosic RINs are more valuable and must reflect the portion of fuel derived from cellulose.
- The 2014 Pathways II Rule allowed producers to calculate a "cellulosic converted fraction" using data from either an analytical method certified by a voluntary consensus standards body (VCSB) or a method supported by peer-reviewed references that would "produce reasonably accurate results."
- Biochemical processing of whole corn kernels yields ethanol from both starch and a small cellulose fraction (kernel fiber); direct measurement of the cellulose-derived portion is difficult, and some producers used "mass closure" (measure non-cellulosic components and infer the remainder is cellulose).
- EPA observed high variability in reported converted fractions, ran a Monte Carlo analysis, and issued the nationally applicable "Cellulosic Guidance" (and a contemporaneous Hudson Letter to POET-Hudson) explaining that peer-reviewed methods must demonstrate accuracy against a "known, representative reference material" and that starch-only/mass-closure approaches are unreliable.
- POET petitioned for review, arguing the Guidance is a legislative rule (invalid without notice-and-comment), conflicts with Pathways II, and imposes impossible requirements; POET-Hudson separately sought relief in the Eighth Circuit.
- The D.C. Circuit held POET’s challenge to the Guidance’s VCSB discussion unripe, concluded the Guidance is final, characterized it as an interpretive rule, and upheld EPA’s interpretation as reasonable; the petition was dismissed in part and denied in part.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Ripeness of challenge to Guidance's discussion of VCSB-certified methods | POET: Guidance unlawfully restricts VCSB pathway now; review appropriate | EPA: No VCSB-certified method exists and POET does not rely on one, so no imminent injury | Court: Unripe — dismiss challenge to VCSB portion (no actual/imminent injury) |
| Finality of the Guidance | POET: Guidance is nonfinal, advisory | EPA: Guidance interpretive and nonfinal; could be revised | Court: Guidance is final agency action (consummation + legal consequences) |
| Whether Guidance is a legislative rule (notice-and-comment) | POET: Reference-material requirement and other constraints effectuate a substantive rule change, so notice-and-comment required | EPA: Guidance merely interprets the Pathways II Rule and refines "reasonable accuracy" standards | Court: Guidance is an interpretive rule (not legislative) as to peer-review interpretation; notice-and-comment not required here |
| Substantive validity — whether EPA acted arbitrarily by requiring (1) demonstration in theory and fact, (2) use of representative reference material, and (3) disallowing mass-closure/starch-only reliance | POET: Requirements are arbitrary, impossible (no reference material exists), and conflict with Pathways II’s delegation to peer review/third parties | EPA: Requirements are reasonable, supported by observed data variability and a Monte Carlo analysis; EPA retains authority to accept/reject peer-review demonstrations | Court: Upheld EPA as reasonable on all three points — Demonstration Requirement, Reference Material Requirement, and Mass-Closure Prohibition (petition denied on merits) |
