Zero Zone, Inc. v. United States Department of Energy
832 F.3d 654
7th Cir.2016Background
- DOE promulgated two 2014 rules for commercial refrigeration equipment (CRE): the New Standards Rule (energy conservation standards for 49 equipment classes) and the 2014 Test Procedure Rule (clarifying measurement of a key dimension, “L”).
- Petitioners (Zero Zone, AHRI, NAFEM) challenged both rules on procedural and substantive APA/EPCA grounds; petitions were consolidated and heard in the Seventh Circuit.
- DOE’s standards relied on a design‑option engineering model using a representative (larger‑end) unit per class, component cost/efficiency tradeoffs, offsets for small units, and validation against market/test data.
- DOE conducted an economic analysis with five trial standard levels, selected the third‑highest level as technologically feasible and economically justified, and monetized environmental benefits using the Social Cost of Carbon (SCC).
- DOJ (Antitrust Division) provided a written determination (later than statutory 60 days), finding no significant anticompetitive effects; DOE relied on that letter in its analysis. DOE also issued a separate clarification defining “L” (allowing up to 10% non‑transparent length) consistent with industry practice.
- The Seventh Circuit denied all petitions, holding DOE’s engineering and economic analyses, consideration of small business impacts, treatment of cumulative regulation, and the 2014 Test Procedure Rule were within statutory authority and not arbitrary or capricious.
Issues
| Issue | Petitioners' Argument | DOE's / Government's Argument | Held |
|---|---|---|---|
| Adequacy of notice and access to DOE’s engineering spreadsheet | DOE provided spreadsheet too late and it lacked manipulability to test manufacturers’ products | Underlying raw data were available earlier; spreadsheet organization did not frustrate meaningful comment; manufacturers could compare models or proposed standards | Court: DOE provided adequate notice and opportunity to comment; no APA defect |
| Validity of engineering model (compressors, insulation, validation) | DOE’s assumptions (10% compressor gain reduced to 2%; half‑inch insulation feasibility) were arbitrary; model needed broader real‑world testing | DOE revised compressor estimates after industry comments (Danfoss); manufacturers confirmed insulation feasibility; DOE validated model against tested units and databases | Court: Model and revisions supported by substantial evidence; agency acted reasonably and validated model sufficiently |
| Economic assumptions: price elasticity and substitution effects | CRE purchasers may substitute used/refurbished equipment or switch designs; demand not price inelastic | DOE lacked data to estimate elasticity; CRE are necessities subject to health codes, so demand relatively inelastic; refurbishing unlikely to change standards ranking | Court: DOE’s elasticity assumption reasonable and entitled to deference |
| Use and scope of Social Cost of Carbon (SCC) in benefits | SCC is beyond EPCA scope or calculated arbitrarily (lack of peer review/transparency) | EPCA permits consideration of national energy conservation and related environmental benefits; DOE relied on interagency SCC work and acknowledged limitations | Court: DOE permissibly considered SCC; SCC application and responses adequate |
| Consideration of anticompetitive effects and DOJ letter timing | DOJ letter lacked detailed analysis and arrived after comment period; late filing and late Federal Register publication procedural errors | EPCA requires Attorney General’s written determination; DOE provided DOJ materials and considered DOJ’s determination; late DOJ letter was harmless because DOE had time to consider and no statutory publication deadline exists | Court: DOE properly relied on DOJ determination; timing error harmless; publication timing not a violation |
| 2014 Test Procedure Rule: definition of "L" and procedural timing | DOE’s clarified definition departs from AHRI Standard 1200 and alters measured energy use; test procedure should have accompanied standards | AHRI Standard lacks a precise “L” definition; DOE’s clarification adopted industry practice (allowing up to 10% non‑transparent area), did not change measured consumption, and was a permissible interpretation/clarification | Court: DOE’s definition conforms to industry standard as implemented; clarifying rule valid and need not have been issued before standards |
