I. Synopsis of the Proposed Determination Title III, Part C 1 of EPCA,2 established the Energy Conservation Program for Certain Industrial Equipment. 42 U.S.C.
63116317 This equipment includes UFHWSTs, the subject of this NOPD.
42 U.S.C. 63111K
Pursuant to EPCA, DOE is triggered to consider amending the energy efficiency standards for certain types of commercial and industrial equipment, including the equipment at issue in this document, whenever the American Society of Heating, Refrigerating, and Air-Conditioning Engineers ASHRAE
amends the standard levels or design requirements prescribed in ASHRAE
Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings, ASHRAE Standard 90.1.
Under a separate provision of EPCA, DOE is required to review the existing energy conservation standards for those types of covered equipment subject to ASHRAE Standard 90.1 every six 6
years to determine whether those standards need to be amended. 42
U.S.C. 6313a6AC DOE is conducting this review of the energy conservation standards for UFHWSTs under EPCAs six-year-lookback authority. 42 U.S.C. 6313a6C
For this proposed determination, DOE
analyzed UFHWSTs subject to standards as specified in the Code of Federal 1 For editorial reasons, upon codification in the U.S. Code, Part C was redesignated Part A1.
2 All references to EPCA in this document refer to the statute as amended through the Energy Act of 2020, Public Law 116260 Dec. 27, 2020.

DOE first analyzed the technological feasibility of more efficient UFHWSTs.
For those UFHWSTs for which DOE
determined higher standards to be technologically feasible, DOE estimated energy savings that would result from potential amended energy conservation standards. DOE also considered whether potential energy conservation standards would be economically justified. As discussed in the following sections, DOE has initially determined that it lacks clear and convincing evidence that amended energy conservation standards for UFHWSTs would result in significant additional conservation of energy or be economically justified.
Based on the results of these analyses, summarized in section V of this document, DOE has tentatively determined that current energy conservation standards for UFHWSTs do not need to be amended.
II. Introduction The following section briefly discusses the statutory authority underlying this proposed determination, as well as some of the historical background relevant to the establishment of energy conservation standards for UFHWSTs.
A. Authority EPCA, Public Law 94163 42 U.S.C.
62916317, as codified, among other things, authorizes DOE to regulate the energy efficiency of a number of consumer products and certain industrial equipment. Title III, Part C of EPCA, added by Public Law 95619, Title IV, 441a 42 U.S.C. 63116317, as codified, established the Energy Conservation Program for Certain Industrial Equipment, which sets forth a variety of provisions designed to improve energy efficiency. This equipment includes UFHWSTs, the subject of this document. 42 U.S.C.
63111K
Under EPCA, the energy conservation program consists essentially of four parts: 1 Testing; 2 labeling; 3 the establishment of Federal energy conservation standards, and 4
certification and enforcement procedures. Relevant provisions of EPCA specifically include definitions 42 U.S.C. 6311, energy conservation standards 42 U.S.C. 6313, test procedures 42 U.S.C. 6314, labeling provisions 42 U.S.C. 6315, and the authority to require information and reports from manufacturers 42 U.S.C.
6316.
