71 F.4th 59
D.C. Cir.2023Background
- Congress enacted the American Innovation and Manufacturing (AIM) Act to phase down hydrofluorocarbons (HFCs) through an allowance-allocation and trading program administered by EPA.
- EPA promulgated a Phasedown Rule implementing caps, an allowance system, reporting/auditing, and compliance measures, including a ban on single-use (disposable) cylinders and a QR-code container-tracking requirement.
- Petitioners: Choice Refrigerants sued claiming (1) EPA lacks authority to require allowances for HFCs contained in blends and (2) the AIM Act unconstitutionally delegates allocation authority (nondelegation). Three trade associations and Worthington Industries challenged the refillable-cylinder ban and QR-code tracking as beyond EPA’s statutory authority.
- The D.C. Circuit reviewed petitions for review under the Clean Air Act’s review provision.
- Holding (overview): Court upheld EPA’s power to regulate HFCs within blends; declined to reach Choice’s nondelegation claim because Choice failed to exhaust administrative remedies; vacated and remanded the refillable-cylinder and QR-code portions of the Phasedown Rule for lacking a statutory basis.
- The court remanded to EPA to justify, revise, or repromulgate the vacated compliance measures consistent with statute.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Authority to require allowances for HFCs contained in blends | Choice: Blended HFC products differ physically/chemically and should not be treated as listed "regulated substances." | EPA: HFC molecules in blends are chemically identical to listed HFCs and thus remain regulated substances subject to allowances. | EPA may regulate HFCs within blends; upheld. |
| Nondelegation challenge to EPA's discretion in allocating allowances | Choice: AIM Act gives EPA unguided, unconstitutional legislative power to allocate allowances. | EPA/Respondents: Allocation authority is statutory; procedural exhaustion required before judicial review. | Court did not reach merits; nondelegation claim barred for failure to exhaust administrative remedies under the Clean Air Act. |
| Authority to impose refillable-cylinder ban and QR-code tracking | Trade associations/Worthington: AIM Act does not authorize rules mandating refillable cylinders or QR-code tracking. | EPA: (k)(1)(A) plus (e)(2)(B) (duty to "ensure" caps are not exceeded) authorize necessary compliance measures, including those rules. | Court vacated the refillable-cylinder and QR-code rules: EPA failed to identify statutory authorization; (e)(2)(B) construed as a cap-calculation/compliance mandate, not a broad grant to adopt these specific measures. Remanded. |
