955 F.3d 68
D.C. Cir.2020Background
- Congress added Title VI to the Clean Air Act (1990) implementing the Montreal Protocol and required EPA to list "safe" and "prohibited" substitutes for ozone-depleting substances (Section 612).
- EPA historically listed many hydrofluorocarbons (HFCs) as acceptable substitutes but promulgated a 2015 Rule reclassifying certain HFCs as unacceptable because of their greenhouse-gas impacts.
- In Mexichem Fluor, Inc. v. EPA, 866 F.3d 451 (D.C. Cir. 2017), this court held EPA could bar future replacements with HFCs but lacked statutory authority under Section 612(c) to force entities that had already replaced ozone-depleting substances with HFCs to replace again; the court therefore vacated the 2015 Rule only "to the extent" it required such second replacements.
- EPA issued a 2018 Federal Register notice (the challenged action) treating Mexichem’s partial vacatur as requiring suspension of the 2015 Rule’s HFC listings in their entirety, thereby allowing even current users of ozone-depleting substances to switch to HFCs; EPA issued that guidance without notice-and-comment.
- NRDC and several states sued; the D.C. Circuit (majority) held petitioners had standing, the 2018 action was final agency action, and the 2018 action was a legislative change implemented without required notice-and-comment, so the court vacated the 2018 Rule and remanded.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Standing | NRDC and states: 2018 Rule increases HFC use → increased climate harms to members/states (coastal damage); vacatur would redress injury | Intervenors: Mexichem already produced the legal effect; 2018 Rule did not cause injury | NRDC and New York have standing; court assumes 2018 Rule independently caused increased HFC use for standing purposes |
| Final agency action (Bennett) | 2018 Rule consummated EPA decisionmaking and changed rights/obligations by suspending HFC listings | EPA/intervenors: Mexichem, not 2018 Rule, produced suspension; 2018 Rule merely implemented court decision | 2018 Rule is final: it consummated agency decisionmaking and independently altered legal rights/obligations |
| Legislative vs interpretive (notice-and-comment) | 2018 Rule was legislative: it amended/suspended a prior legislative rule and had legal effect; thus APA/Title VI procedures required notice-and-comment | EPA: 2018 action was interpretive—merely implementing Mexichem’s vacatur—so notice-and-comment unnecessary | 2018 Rule was legislative (it expanded Mexichem’s partial vacatur into full vacatur); EPA violated notice-and-comment requirements |
| Remedy / Arbitrary & Capricious | Petitioners: procedural defect requires vacatur; also challenged substantive reasonableness | Intervenors/EPA: any procedural error harmless; 2018 Rule merely clarified Mexichem | Court vacated the 2018 Rule as procedurally invalid and remanded; did not reach substantive arbitrary-and-capricious claims |
