I. Authority and Background
A. Authority
The Energy Policy and Conservation Act, Public Law 94-163, as amended (“EPCA”), authorizes DOE to regulate the energy efficiency of a number of consumer products and certain industrial equipment. (42 U.S.C. 6291-6317, as codified) Title III, Part B of EPCA established the Energy Conservation Program for Consumer Products Other Than Automobiles, which sets forth a variety of provisions designed to improve energy efficiency, while Title III, Part C of EPCA, added by Public Law 95-619, Title IV, section 441(a), established the Energy Conservation Program for Certain Industrial Equipment, which sets forth a variety of provisions designed to improve energy efficiency. These products and equipment include central air conditioners and heat pumps (“CAC/HPs”), dishwashers (“DWs”), residential clothes washers (“RCWs”), pool heaters, dehumidifiers, external power supplies (“EPSs”), battery chargers, computer room air conditioners (“CRACs”), direct-expansion dedicated outdoor air systems (“DX-DOASes”), air-cooled, three-phase, small commercial package air conditioners and heat pumps with a cooling capacity of less than 65,000 Btu/h (“three-phase, less than 65,000 Btu/h ACUACs and ACUHPs”) and air-cooled, three-phase variable refrigerant flow air conditioners and heat pumps with a cooling capacity of less than 65,000 Btu/h (“three-phase, less than 65,000 Btu/h VRF”), commercial water heating equipment (“CWHs”), automatic commercial ice makers (“ACIMs”), walk-in coolers and walk-in freezers (“walk-ins”), commercial and industrial pumps, portable air conditioners (“portable ACs”), compressors, dedicated-purpose pool pump motors (“DPPPMs”), air cleaners, single package vertical units (“SPVUs”), ceiling fan light kits (“CFLKs”), and general service lamps (“GSLs”), all of which are subjects of this document. (42 U.S.C. 6292(a)(3), (6-7), (11), and (20); 42 U.S.C. 6295(i)(6), (u), (cc), and (ff); 42 U.S.C. 6311(1)(A-D), (F-G), (K), and (2)(B)(i)).
All references to EPCA in this document refer to the statute as amended through the Energy Act of 2020, Public Law 116-260 (Dec. 27, 2020), which reflect the last statutory amendments that impact Parts A and A-1 of EPCA.
For editorial reasons, upon codification in the U.S. Code, Part B was redesignated Part A.
For editorial reasons, upon codification in the U.S. Code, Part C was redesignated Part A-1.
The energy conservation program under EPCA consists essentially of four parts: (1) testing, (2) labeling, (3) Federal energy conservation standards, and (4) certification and enforcement procedures. Relevant provisions of EPCA specifically include definitions (42 U.S.C. 6291; 42 U.S.C. 6311), test procedures (42 U.S.C. 6293; 42 U.S.C. 6314), labeling provisions (42 U.S.C. 6294; 42 U.S.C. 6315), energy conservation standards (42 U.S.C. 6295; 42 U.S.C. 6313), and the authority to require information and reports from manufacturers (42 U.S.C. 6316; 42 U.S.C. 6296).
The Federal testing requirements consist of test procedures that manufacturers of covered products and equipment must use as the basis for: (1) certifying to DOE that their products or equipment comply with the applicable energy conservation standards adopted under EPCA (42 U.S.C. 6295(s); 42 U.S.C. 6316(a); 42 U.S.C. 6316(b); 42 U.S.C. 6296), and (2) making other representations about the efficiency of those products or equipment (42 U.S.C. 6293(c); 42 U.S.C. 6314(d)). Similarly, DOE must use these test procedures to determine whether the products or equipment comply with any relevant standards promulgated under EPCA. (42 U.S.C. 6295(s); 42 U.S.C. 6316(a); 42 U.S.C. 6316(b); 42 U.S.C. 6296).
EPCA authorizes DOE to enforce compliance with the energy and water conservation standards established for covered products and equipment. (42 U.S.C. 6299-6305; 42 U.S.C. 6316(a)-(b)) DOE has promulgated certification and/or enforcement regulations that include reporting requirements for covered products and equipment including CAC/HPs, DWs, RCWs, pool heaters, dehumidifiers, EPSs, battery chargers, CRACs, three-phase, less than 65,000 Btu/h ACUACs and ACUHPs, three-phase, less than 65,000 Btu/h VRF, CWHs, ACIMs, walk-ins, commercial and industrial pumps, portable ACs, compressors, SPVUs, CFLKs, and GSLs. DOE is establishing certification and reporting requirements for DX-DOASes, DPPPMs, and air cleaners. See10 CFR part 429. Additionally, DOE is amending labeling requirements for walk-ins. See10 CFR 431.305. The reporting requirements ensure that DOE has the information it needs to assess whether regulated products and equipment sold in the United States comply with the statutory and regulatory requirements applicable to each covered product and equipment type.
B. Background
DOE's certification regulations are a mechanism that DOE uses to help ensure compliance with its regulations by collecting information about the energy and water use characteristics of covered products and covered equipment distributed in commerce in the United States. Manufacturers of most covered products and covered equipment must submit a certification report for the duration of distribution, specifically (1) before a basic model is distributed in commerce, (2) annually thereafter, and (3) if the basic model is redesigned in a manner that increases the consumption or decreases the efficiency of the basic model such that the certified rating is no longer supported by test data. 10 CFR 429.12. Additionally, manufacturers must report when production of a basic model has ceased and is no longer offered for sale as part of the next annual certification report following such cessation. 10 CFR 429.12(f). DOE requires the manufacturer of any covered product or covered equipment to establish, maintain, and retain the records of certification reports, of the underlying test data for all certification testing, and of any other testing conducted to satisfy the requirements of 10 CFR parts 429, 430, and/or 10 CFR part 431 until 2 years after notifying DOE that a model has been discontinued. 10 CFR 429.71. Certification reports provide DOE and consumers with comprehensive, up-to-date efficiency information and support effective enforcement.
To ensure that all covered products and covered equipment distributed in the United States comply with DOE's energy and water conservation standards and reporting requirements, DOE has promulgated certification, compliance, and enforcement regulations in 10 CFR parts 429 and 431. On March 7, 2011, DOE published in the Federal Register a final rule regarding certification, compliance, and enforcement for consumer products and commercial and industrial equipment, which revised, consolidated, and streamlined DOE's existing certification, compliance, and enforcement regulations for certain consumer products and commercial and industrial equipment covered under EPCA. See76 FR 12422. Since that time, DOE has completed multiple rulemakings regarding certification, compliance, and enforcement for specific covered products or equipment. See79 FR 25486 (the May 5, 2014 Final Rule specific to certification of commercial and industrial heating, ventilation, and air conditioning (“HVAC”), refrigeration, and water heating equipment) and 87 FR 43952 (the July 22, 2022 Final Rule amending certification provisions for CFLKs, general service incandescent lamps, incandescent reflector lamps, ceiling fans, consumer furnaces and boilers, consumer water heaters, DWs, commercial clothes washers, battery charges, and DPPPMs).
Additionally, if the Secretary has prescribed test procedures under section 6314 for any class of covered equipment, the Secretary shall prescribe a labeling rule applicable to such class of covered equipment. See42 U.S.C. 6315(a). EPCA, however, also sets out certain criteria that must be met prior to prescribing a given labeling rule. Specifically, to establish these requirements, DOE must determine that: (1) labeling in accordance with section 6315 is technologically and economically feasible with respect to any particular equipment class; (2) significant energy savings will likely result from such labeling; and (3) labeling in accordance with section 6315 is likely to assist consumers in making purchasing decisions. (42 U.S.C. 6315(h))
If these criteria are met, EPCA specifies certain aspects of equipment labeling that DOE must consider in any rulemaking establishing labeling requirements for covered equipment. At a minimum, such labels must include the energy efficiency of the affected equipment, as tested under the prescribed DOE test procedure, and may also require disclosure of the estimated operating costs and energy use. (42 U.S.C. 6315(b)) The labeling provisions shall include requirements the Secretary determines are likely to assist purchasers in making purchasing decisions, such as: requirements and directions for the display of the label; requirements for including on any label, or separately attaching to, or shipping with, the covered equipment, such as additional information related to energy efficiency, energy use, and other measures of energy consumption, including instructions for maintenance and repair of the covered equipment, as the Secretary determines is necessary to provide adequate information to purchasers; and requirements that printed matter displayed or distributed with the equipment at the point of sale also include the information required to be placed on the label. (42 U.S.C. 6315(c)).
DOE published a notice of proposed rulemaking (“NOPR”) in the Federal Register on September 29, 2023, that proposed to amend the certification, reporting, and labeling requirements for the products and equipment that are the subjects of this final rule. 88 FR 67458 (“September 2023 CCE NOPR”). DOE held a public meeting related to this NOPR on October 26, 2023 (hereafter, the “NOPR public meeting”).
DOE received comments in response to the September 2023 CCE NOPR from the interested parties listed in Table I.1.
Table I.1—List of Commenters With Written Submissions in Response to the September 2023 CCE NOPR
AHAM comment nos. 9 and 19 are identical. Therefore, DOE only cites no. 19 in the discussion section of this final rule.
