I. Synopsis of the Proposed Rule 
The Energy Policy and Conservation 
Act, Public Law 94–163, as amended (‘‘EPCA’’),
1authorizes DOE to regulate 
the energy efficiency of a number of consumer products and certain industrial equipment. (42 U.S.C. 6291– 6317) Title III, Part B of EPCA
2 
established the Energy Conservation Program for Consumer Products Other Than Automobiles. (42 U.S.C. 6291– 6309) These products include refrigerators, refrigerator-freezers, and freezers, the subject of this proposed rulemaking. 
Pursuant to EPCA, any new or 
amended energy conservation standard must, among other things, be designed to achieve the maximum improvement in energy efficiency that DOE determines is technologically feasible and economically justified. (42 U.S.C. 6295(o)(2)(A)) Furthermore, the new or 
amended standard must result in significant conservation of energy. (42 U.S.C. 6295(o)(3)(B)) In light of the above and under the 
authority provided by 42 U.S.C. 
6295(p)(4), DOE is proposing this rule establishing and amending the energy conservation standards for refrigerators, refrigerator-freezers, and freezers and is concurrently issuing a direct final rule elsewhere in this issue of the Federal Register. DOE will proceed with this notice of proposed rulemaking only if it determines it must withdraw the direct 
final rule pursuant to the criteria provided in 42 U.S.C. 6295(p)(4). The amended standard levels in the proposed rule and the direct final rule were proposed in a letter submitted to DOE jointly by groups representing manufacturers, energy and environmental advocates, consumer groups, and a utility. This letter, titled ‘‘Energy Efficiency Agreement of 2023’’ (hereafter, the ‘‘Joint Agreement’’
3), 
recommends specific energy conservation standards for residential refrigerators, refrigerator-freezers, and freezers that, in the commenters’ view, would satisfy the EPCA requirements in 42 U.S.C. 6295(o). DOE subsequently received letters of support from States including New York, California, and Massachusetts
4and utilities including 
San Diego Gas and Electric and Southern California Edison
5advocating 
for the adoption of the recommended standards. As discussed in more detail in the accompanying direct final rule and in accordance with the provisions at 42 U.S.C. 6295(p)(4), DOE has 
determined that the recommendations contained in the Joint Agreement comply with the requirements of 42 U.S.C. 6295(o). 
In accordance with these and other 
statutory provisions discussed in this document, DOE proposes new and amended energy conservation standards for refrigerators, refrigerator-freezers, and freezers. The standards for refrigerators, refrigerator-freezers, and freezers are expressed in terms of integrated annual energy use (‘‘AEU’’), measured in kilowatt-hours per year (‘‘kWh/year’’), as measured according to DOE’s current test procedure codified at title 10 of the Code of Federal Regulations (‘‘CFR’’) part 430, subpart B, appendices A (‘‘appendix A’’) and B (‘‘appendix B’’). 
Table I.1 and Table I.2 present the 
proposed standards for refrigerators, refrigerator-freezers, and freezers. The proposed standards the same as those recommended by the Joint Agreement. These standards apply to all products listed in Table I.1 and manufactured in, or imported into the United States starting on January 31, 2029, and all products listed in Table I.2 and manufactured in, or imported into, the United States starting on January 31, 2030, as recommended in the Joint Agreement.

II. Introduction 
The following section briefly 
discusses the statutory authority 
underlying this proposed rule, as well 
as some of the relevant historical background related to the establishment of standards for refrigerators, refrigerator-freezers, and freezers. 
A. Authority 
EPCA authorizes DOE to regulate the 
energy efficiency of a number of 
consumer products and certain industrial equipment. Title III, Part B of EPCA established the Energy Conservation Program for Consumer Products Other Than Automobiles. These products include refrigerators, refrigerator-freezers, and freezers, the subject of this document. (42 U.S.C. 6292(a)(1)) EPCA prescribed energy conservation standards for these products (42 U.S.C. 6295(b)(1)), and directs DOE to conduct future rulemakings to determine whether to amend these standards. (42 U.S.C. 6295(b)(3)) EPCA further provides that, not later than 6 years after the issuance of any final rule establishing or amending a standard, DOE must publish either a notice of determination that standards for the product do not need to be amended, or a NOPR including new proposed energy conservation standards (proceeding to a final rule, as appropriate). (42 U.S.C. 6295(m)(1)) 
The energy conservation program 
under EPCA 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. 6291), test procedures (42 U.S.C. 6293), labeling provisions (42 U.S.C. 6294), energy conservation standards (42 U.S.C. 6295), and the authority to require information and reports from manufacturers (42 U.S.C. 
6296). 
Federal energy efficiency 
requirements for covered products established under EPCA generally supersede State laws and regulations concerning energy conservation testing, labeling, and standards. (42 U.S.C. 6297(a)–(c)) DOE may, however, grant waivers of Federal preemption for particular State laws or regulations, in accordance with the procedures and other provisions set forth under EPCA. (see 42 U.S.C. 6297(d)) 
Subject to certain criteria and 
conditions, DOE is required to develop test procedures to measure the energy efficiency, energy use, or estimated annual operating cost of each covered product. (42 U.S.C. 6295(o)(3)(A) and (r)) Manufacturers of covered products must use the prescribed DOE test procedure as the basis for certifying to DOE that their products comply with the applicable energy conservation standards adopted under EPCA and when making representations to the public regarding the energy use or efficiency of those products. (42 U.S.C. 6293(c) and 6295(s)) Similarly, DOE must use these test procedures to determine whether the products comply with standards adopted pursuant to EPCA. (42 U.S.C. 6295(s)) The DOE test procedures for refrigerators, refrigerator- freezers, and freezers appear at title 10 of the Code of Federal Regulations (‘‘CFR’’) part 430, subpart B, appendices A (‘‘appendix A’’) and B (‘‘appendix B’’). 
DOE must follow specific statutory 
criteria for prescribing new or amended standards for covered products, including refrigerators, refrigerator- 
freezers, and freezer. Any new or amended standard for a covered product must be designed to achieve the maximum improvement in energy efficiency that the Secretary of Energy determines is technologically feasible and economically justified. (42 U.S.C. 6295(o)(2)(A) Furthermore, DOE may not adopt any standard that would not result in the significant conservation of energy. (42 U.S.C. 6295(o)(3)) 
Moreover, DOE may not prescribe a 
standard: (1) for certain products, including refrigerators, refrigerators- freezers, and freezers, if no test procedure has been established for the product, or (2) if DOE determines by rule that the standard is not technologically feasible or economically justified. (42 U.S.C. 6295(o)(3)(A)–(B)) In deciding whether a proposed standard is economically justified, DOE must determine whether the benefits of the standard exceed its burdens. (42 U.S.C. 6295(o)(2)(B)(i)) DOE must make this determination after receiving comments on the proposed standard, and by considering, to the greatest extent practicable, the following seven statutory factors: 
(1) The economic impact of the 
standard on manufacturers and consumers of the products subject to the standard; 
(2) The savings in operating costs 
throughout the estimated average life of the covered products in the type (or class) compared to any increase in the price, initial charges, or maintenance expenses for the covered products that are likely to result from the standard; 
(3) The total projected amount of 
energy (or as applicable, water) savings likely to result directly from the standard; 
(4) Any lessening of the utility or the 
performance of the covered products likely to result from the standard; 
(5) The impact of any lessening of 
competition, as determined in writing by the Attorney General, that is likely to result from the standard; 
(6) The need for national energy and 
water conservation; and 
(7) Other factors the Secretary of 
Energy (‘‘Secretary’’) considers relevant. (42 U.S.C. 6295(o)(2)(B)(i)(I)–(VII)) 
VerDate Sep<11>2014 17:25 Jan 16, 2024 Jkt 262001 PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 E:\FR\FM\17JAP1.SGM 17JAP1lotter on DSK11XQN23PROD with PROPOSALS12890 Federal Register / Vol. 89, No. 11 / Wednesday, January 17, 2024 / Proposed Rules 
Further, EPCA establishes a rebuttable 
presumption that a standard is 
economically justified if the Secretary finds that the additional cost to the consumer of purchasing a product complying with an energy conservation standard level will be less than three times the value of the energy savings during the first year that the consumer will receive as a result of the standard, as calculated under the applicable test procedure. (42 U.S.C. 6295(o)(2)(B)(iii)) 
EPCA, as codified also contains what 
is known as an ‘‘anti-backsliding’’ provision, which prevents the Secretary from prescribing any amended standard that either increases the maximum allowable energy use or decreases the minimum required energy efficiency of a covered product. (42 U.S.C. 6295(o)(1)) Also, the Secretary may not prescribe an amended or new standard if interested persons have established by a preponderance of the evidence that the standard is likely to result in the unavailability in the United States in any covered product type (or class) of performance characteristics (including reliability), features, sizes, capacities, and volumes that are substantially the same as those generally available in the United States. (42 U.S.C. 6295(o)(4)) 
EPCA specifies requirements when 
promulgating an energy conservation 
standard for a covered product that has two or more subcategories. DOE must specify a different standard level for a type or class of product that has the same function or intended use, if DOE determines that products within such group: (A) consume a different kind of energy from that consumed by other covered products within such type (or class); or (B) have a capacity or other performance-related feature which other products within such type (or class) do not have and such feature justifies a higher or lower standard. (42 U.S.C. 6295(q)(1)) In determining whether a performance-related feature justifies a different standard for a group of products, DOE must consider such factors as the utility to the consumer of the feature and other factors DOE deems appropriate. Id. Any rule prescribing 
such a standard must include an explanation of the basis on which such higher or lower level was established. (42 U.S.C. 6295(q)(2)) 
Additionally, pursuant to the 
amendments contained in the Energy Independence and Security Act of 2007 
(‘‘EISA 2007’’), Public Law 110–140, any final rule for new or amended energy conservation standards promulgated after July 1, 2010, is required to address standby mode and off mode energy use. (42 U.S.C. 6295(gg)(3)) Specifically, when DOE adopts a standard for a covered product after that date, it must, if justified by the criteria for adoption of standards under EPCA (42 U.S.C. 6295(o)), incorporate standby mode and off mode energy use into a single standard, or, if that is not feasible, adopt a separate standard for such energy use for that product. (42 U.S.C. 6295(gg)(3)(A)–(B)) DOE’s current test procedures for refrigerators, refrigerator-freezers, and freezers address standby mode and off mode energy use. 
Finally, EISA 2007 amended EPCA, in 
relevant part, to grant DOE authority to directly issue a final rule (i.e., a ‘‘direct 
final rule’’) establishing an energy conservation standard on receipt of a statement submitted jointly by interested persons that are fairly representative of relevant points of view (including representatives of manufacturers of covered products, States, and efficiency advocates), as determined by the Secretary, that contains recommendations with respect to an energy or water conservation standard (42 U.S.C. 6295(p)(4)) Pursuant to 42 U.S.C. 6295(p)(4), the Secretary must also determine whether a jointly- submitted recommendation for an energy or water conservation standard 
satisfies 42 U.S.C. 6295(o). 
A NOPR that proposes an identical 
energy efficiency standard must be published simultaneously with the direct final rule, and DOE must provide a public comment period of at least 110 days on this proposal. (42 U.S.C. 6295(p)(4)(A)–(B)) Based on the comments received during this period, the direct final rule will either become effective, or DOE will withdraw it not later than 120 days after its issuance if (1) one or more adverse comments is received, and (2) DOE determines that those comments, when viewed in light of the rulemaking record related to the direct final rule, may provide a reasonable basis for withdrawal of the direct final rule under 42 U.S.C. 6295(o). (42 U.S.C. 6295(p)(4)(C)) Receipt of an alternative joint recommendation may also trigger a DOE 
withdrawal of the direct final rule in the same manner. Id. After withdrawing a 
direct final rule, DOE must proceed with the notice of proposed rulemaking published simultaneously with the direct final rule and publish in the Federal Register the reasons why the direct final rule was withdrawn. Id. 
DOE has previously explained its 
interpretation of its direct final rule authority. In a final rule amending the Department’s ‘‘Procedures, Interpretations and Policies for Consideration of New or Revised Energy Conservation Standards for Consumer Products’’ at 10 CFR part 430, subpart C, appendix A, DOE noted that it may issue standards recommended by interested persons that are fairly representative of relative points of view as a direct final rule when the recommended standards are in accordance with 42 U.S.C. 6295(o) or 6313(a)(6)(B), as applicable. 86 FR 70892, 70912 (Dec. 13, 2021). But the direct final rule provision in EPCA, under which this proposed rule is 
issued, does not impose additional requirements applicable to other standards rulemakings, which is consistent with the unique circumstances of rules issued as consensus agreements under DOE’s direct final rule authority. Id. DOE’s 
discretion remains bounded by its statutory mandate to adopt a standard that results in the maximum improvement in energy efficiency that is technologically feasible and economically justified—a requirement found in 42 U.S.C. 6295(o). Id. As such, 
DOE’s review and analysis of the Joint Agreement is limited to whether the recommended standards satisfy the criteria in 42 U.S.C. 6295(o). 
B. Background 1. Current Standards 
In a final rule published on 
September 15, 2011, DOE prescribed the 
current energy conservation standards for refrigerators, refrigerator-freezers, and freezers. 76 FR 57516 (‘‘September 2011 Final Rule’’). These standards are set forth in DOE’s regulations at 10 CFR 430.32(a) and are shown in Table I.2. These standards are expressed in terms of kilo-watt hours per year (‘‘kWh/yr’’).

2. Current Test Procedure 
On October 12, 2021, DOE published 
a test procedure final rule (‘‘October 
2021 TP Final Rule’’) establishing test procedures for refrigerators, refrigerator- freezers, and freezers, at 10 CFR part 430, subpart B, appendices A (‘‘appendix A’’) and B (‘‘appendix B’’). 86 FR 56790. The test procedure adopted the latest version of the relevant industry standard published by the Association of Home Appliance Manufacturers (‘‘AHAM’’), updated in 2019, AHAM Standard HRF–1, ‘‘Energy 
and Internal Volume of Refrigerating Appliances’’ (‘‘HRF–1–2019’’). 10 CFR 430.3(i)(4). The standard levels proposed in this NOPR are based on the AEU metrics as measured according to appendix A and appendix B. 
3. History of Standards Rulemaking for 
Refrigerators, Refrigerator-Freezers, and Freezers, and Freezers 
The National Appliance Energy 
Conservation Act of 1987 (‘‘NAECA’’), Public Law 100–12, amended EPCA to establish prescriptive standards for refrigeration products, with requirements that DOE conduct two cycles of rulemakings to determine whether to amend these standards (42 U.S.C. 6295 (b)(1), (2), (3)(A)(i), and (3)(B)–(C)). DOE completed the first of these rulemaking cycles in 1989 and 1990 by adopting amended performance standards for all refrigeration products manufactured on or after January 1, 1993. 54 FR 47916 (November 17, 1989); 55 FR 42845 (October 24, 1990). DOE Completed a second rulemaking cycle to amend the standards for refrigeration products by issuing a final rule in 1997, which adopted the current standards for these products. 62 FR 23102 (April 28, 1997). 
In 2005, DOE granted a petition, 
submitted by a coalition of state governments, utility companies, consumer and low-income advocacy groups, and environmental and energy efficiency organizations, requesting a rulemaking to amend the standards for residential refrigerator-freezers. DOE then conducted limited analyses to examine the technological and economic feasibility of amended standards at the ENERGY STAR levels that were in effect for 2005 for the two most popular product classes of refrigerator-freezers. These analyses not only identified potential energy savings, benefits, and burdens from such standards, but also assessed other issues related to them. 
DOE initiated a rulemaking and also 
published a notice announcing the availability of the framework document and a public meeting to discuss the document in September 2008. It also requested public comment on the published document. 73 FR 54089 (September 18, 2008). The framework document described the procedural and analytical approaches that DOE anticipated using to evaluate energy conservation standards for refrigeration products and identified various issues to resolve during the rulemaking. DOE published a final rule on September 15, 2011, to satisfy the statutory requirement that DOE publish a final rule to determine whether to amend the standards for refrigeration products manufactured in 2014. (42 U.S.C. 6295(b)(4)) The limited 2005 analyses served as background for the more extensive analysis conducted for final rule published on September 15, 2011. 76 FR 57516. 
4. The Joint Agreement 
On September 25, 2023, DOE received 
the Joint Agreement for various 
consumer products, including refrigerators, refrigerator-freezers, and freezers, submitted jointly by groups representing manufacturers, energy and environmental advocates, consumer groups, and a utility.
6The Joint 
Agreement recommends amended standard levels for refrigerators, refrigerator-freezers, and freezers as presented in Table II.3. (Joint Agreement, No. 103 at p. 4) Details of the Joint Agreement recommendations for other products are provided in the Joint Agreement posted in the docket.

DOE has evaluated the Joint 
Agreement and believes that it meets the 
EPCA requirements for issuance of a direct final rule. As a result, DOE published a direct final rule establishing energy conservation standards for refrigerators, refrigerator-freezers, and freezers elsewhere in this issue of the Federal Register. If DOE receives adverse comments that may provide a reasonable basis for withdrawal and withdraws the direct final rule, DOE will consider those comments and any other comments received in determining how to proceed with this proposed rule. 
For further background information 
on these proposed standards and the supporting analyses, please see the direct final rule published elsewhere in this issue of the Federal Register. That document and the accompanying technical support document (‘‘TSD’’) contain an in-depth discussion of the analyses conducted in evaluating the Joint Agreement, the methodologies DOE used in conducting those analyses, and the analytical results. 
DOE also notes that it was conducting 
a rulemaking to consider amending the standards for refrigerators, refrigerator- freezers, and freezers when the Joint 
Agreement was submitted. As part of that process, DOE published a NOPR and announced a public webinar to respond to initial comments on February 27, 2023 (‘‘February 2023 NOPR’’). 88 FR 12452. DOE also held a public webinar on April 11, 2023, to discuss and receive comments on the February 2023 NOPR and NOPR TSD. The NOPR TSD is available at: www.regulations.gov/document/EERE- 2017-BT-STD-0003-0045. 
III. Proposed Standards 
When considering new or amended 
energy conservation standards, the 
standards that DOE adopts for any type (or class) of covered product must be designed to achieve the maximum improvement in energy efficiency that the Secretary determines is technologically feasible and economically justified. (42 U.S.C. 6295(o)(2)(A)) In determining whether a standard is economically justified, the 
Secretary must determine whether the benefits of the standard exceed its burdens by, to the greatest extent practicable, considering the seven statutory factors discussed previously. (42 U.S.C. 6295(o)(2)(B)(i)) The new or amended standard must also result in significant conservation of energy. (42 U.S.C. 6295(o)(3)(B)) 
DOE considered the impacts of 
amended standards for refrigerators, refrigerator-freezers, and freezers at each trial standard level (‘‘TSL’’), beginning with the maximum technologically feasible (‘‘max-tech’’) level, to determine whether that level was economically justified. Where the max-tech level was not justified, DOE then considered the next most efficient level and undertook the same evaluation until it reached the highest efficiency level that is both technologically feasible and economically justified and saves a significant amount of energy. DOE refers to this process as the ‘‘walk-down’’ analysis. 
To aid the reader as DOE discusses 
the benefits and/or burdens of each TSL, tables in this section present a summary of the results of DOE’s quantitative analysis for each TSL. In addition to the quantitative results presented in the tables, DOE also considers other burdens and benefits that affect economic justification. These include the impacts on identifiable subgroups of consumers who may be disproportionately affected by a national standard and impacts on employment. 
DOE also notes that the economics 
literature provides a wide-ranging discussion of how consumers trade off upfront costs and energy savings in the 
absence of government intervention. Much of this literature attempts to explain why consumers appear to undervalue energy efficiency improvements. There is evidence that consumers undervalue future energy savings as a result of (1) a lack of information; (2) a lack of sufficient salience of the long-term or aggregate benefits; (3) a lack of sufficient savings to warrant delaying or altering purchases; (4) excessive focus on the short term, in the form of inconsistent weighting of future energy cost savings relative to available returns on other investments; (5) computational or other difficulties associated with the evaluation of relevant tradeoffs; and (6) a divergence in incentives (for example, between renters and owners, or builders and purchasers). Having less than perfect foresight and a high degree of uncertainty about the future, consumers may trade off these types of investments at a higher than expected rate between current consumption and uncertain future energy cost savings. 
In DOE’s current regulatory analysis, 
potential changes in the benefits and costs of a regulation due to changes in consumer purchase decisions are included in two ways. First, if consumers forego the purchase of a product in the standards case, this decreases sales for product manufacturers, and the impact on manufacturers attributed to lost revenue is included in the manufacturer impact analysis (‘‘MIA’’). Second, DOE accounts for energy savings attributable only to products actually used by consumers in the standards case; if a standard decreases the number of products purchased by consumers, this decreases the potential energy savings from an energy conservation standard. DOE provides estimates of shipments and changes in the volume of product purchases in chapter 9 of the direct final rule TSD
8available in the docket for 
this rulemaking. However, DOE’s current analysis does not explicitly control for heterogeneity in consumer preferences, preferences across subcategories of products or specific features, or consumer price sensitivity variation according to household income. 
While DOE is not prepared at present 
to provide a fuller quantifiable framework for estimating the benefits

and costs of changes in consumer 
purchase decisions due to an energy conservation standard, DOE is committed to developing a framework that can support empirical quantitative tools for improved assessment of the consumer welfare impacts of appliance standards. DOE has posted a paper that discusses the issue of consumer welfare impacts of appliance energy conservation standards, and potential enhancements to the methodology by which these impacts are defined and estimated in the regulatory process. DOE welcomes comments on how to more fully assess the potential impact of 
energy conservation standards on consumer choice and how to quantify this impact in its regulatory analysis in future rulemakings. 
A. Benefits and Burdens of TSLs 
Considered for Refrigerator, Refrigerator-freezer, and Freezer Standards 
Table III.1 and Table III.2 summarize 
the quantitative impacts estimated for each TSL for refrigerators, refrigerator- freezers, and freezers. The national impacts are measured over the lifetime of refrigerators, refrigerator-freezers, and freezers purchased in the 30-year period 
that begins in the anticipated year of compliance with amended standards (2027–2056 for all TSLs except TSL 4; for TSL 4, 2029–2058 for the product classes listed in Table III.3 and 2030– 2059 for the product classes listed in Table IIII.4). The energy savings, emissions reductions, and value of emissions reductions refer to full-fuel- cycle (‘‘FFC’’) results. The efficiency levels contained in each TSL are described in section V.A of the direct final rule published elsewhere in this issue of the Federal Register.

listed in Table IIII.4. These results include consumer, climate, and health benefits that accrue after 2056 from the products shipped during the period 2027–2056 for all TSLs except TSL 4; for TSL 4, 2029–2058 for the product classes listed in Table III.3 and 2030–2059 for the product classes listed in Table IIII.4. 
* Climate benefits are calculated using four different estimates of the four different estimates of the social cost of carbon (S C–CO
2), methane 
(SC–CH 4), and nitrous oxide (SC–N 2O) (model average at 2.5 percent, 3 percent, and 5 percent discount rates; 95th percentile at 3 percent dis-
count rate). Together, these represent the global SC–GHG. For presentational purposes of this table, the climate benefits associated with the av-erage SC–GHG at a 3 percent discount rate are shown; however, DOE emphasizes the importance and value of considering the benefits cal-culated using all four sets of SC–GHG estimates. To monetize the benefits of reducing GHG emissions, this analysis uses the interim estimates presented in the Technical Support Document: Social Cost of Carbon, Methane, and Nitrous Oxide Interim Estimates Under Executive Order 13990 published in February 2021 by the Interagency Working Group (‘‘IWG’’) on the Social Cost of Greenhouse Gases. See 
www.whitehouse.gov/wp-content/uploads/2021/02/TechnicalSupportDocument_ SocialCostofCarbonMethaneNitrousOxide.pdf. 
** Health benefits are calculated using benefit-per-ton values for NO
Xand SO 2. DOE is currently only monetizing (for NO Xand SO 2) PM 2.5pre-
cursor health benefits and (for NO X) ozone precursor health benefits, but will continue to assess the ability to monetize other effects such as 
health benefits from reductions in direct PM 2.5emissions. The health benefits are presented at real discount rates of 3 and 7 percent. For more 
details, see section IV.L of the direct final rule published elsewhere in this issue of the Federal Register.

and 2030 for PCs 3, 5, 7, and 9. 
DOE first considered TSL 6, which 
represents the max-tech efficiency 
levels. At this level, DOE expects that all product classes would require vacuum-insulated panels (‘‘VIPs’’) and most would require variable-speed compressor (‘‘VSCs’’). For most product classes, this represents the use of VIPs for roughly half the cabinet surface (typically side walls and doors for an upright cabinet), the best-available- efficiency variable-speed compressor, 
forced-convection heat exchangers with multi-speed brush-less direct current (‘‘BLDC’’) fans, variable defrost, and increase in cabinet wall thickness for some classes (e.g., compact refrigerators and both standard-size and compact 
chest freezers). DOE estimates that less than 1 percent of annual shipments across all refrigerator, refrigerator- 
freezer, and freezer product classes currently meet the max-tech efficiencies required. TSL 6 would save an estimated 9.57 quads of energy, an amount DOE considers significant. Under TSL 6, the net present value (‘‘NPV’’) of consumer benefit would be $5.23 billion using a discount rate of 7 percent, and $25.42 billion using a discount rate of 3 percent. 
The cumulative emissions reductions 
at TSL 6 are 176 Mt of CO
2, 55.5 
thousand tons of SO 2, 323 thousand tons of NO X, 0.38 tons of Hg, 1,455 
thousand tons of CH 4, and 1.75 
thousand tons of N 2O. The estimated 
monetary value of the climate benefits from reduced GHG emissions (associated with the average SC–GHG at a 3-percent discount rate) at TSL 6 is $9.29 billion. The estimated monetary value of the health benefits from reduced SO
2and NO Xemissions at TSL 
6 is $7.12 billion using a 7-percent discount rate and $18.24 billion using a 3-percent discount rate.

9Current shipments calculations relied on 
shipments in the year 2023. rate case for climate benefits from 
reduced GHG emissions, the estimated total NPV at TSL 6 is $21.64 billion. Using a 3-percent discount rate for all benefits and costs, the estimated total NPV at TSL 6 is $52.96 billion. The estimated total NPV is provided for additional information, however DOE primarily relies upon the NPV of consumer benefits when determining whether a standard level is economically justified. 
At TSL 6, for the largest product 
classes, which are 3, 5, 5A, and 7 and together account for approximately 76 percent of annual shipments, there is a life-cycle cost (‘‘LLC’’) savings of $0.03, $20.22, $122.18, and $69.71 and a payback period of 9.3 years, 8.6 years, 6.0 years and 6.8 years, respectively. However, for these product classes, the fraction of customers experiencing a net LCC cost is 67.1 percent, 60.3 percent, 39.4 percent and 48.3 percent with increases in first cost of $169.37, $151.75, $161.65, and $153.01, respectively. Overall, a majority of refrigerators, refrigerator-freezers, and freezers consumers (60 percent) would experience a net cost and the average LCC savings would be negative for PC 5BI, PC 10, PC 11A, and PC 18. Additionally, 35 percent of low-income households with a side-by-side refrigerator-freezer (represented by PC 7 and used by 19 percent of low-income households) would experience a net cost. 
At TSL 6, the projected change in 
industry net present value (‘‘INPV’’) ranges from a decrease of $1.83 billion to a decrease of $1.30 billion, which corresponds to decreases of 37.2 percent and 26.5 percent, respectively. Industry conversion costs could reach $2.39 billion as manufacturers work to redesign their portfolio of model offerings and re-tool entire factories to comply with amended standards at TSL 6. 
DOE estimates that less than 1 percent 
of refrigerator, refrigerator-freezer, and freezer current annual shipments meet the max-tech levels. At TSL 6, only a few manufacturers offer any standard- size products that meet the efficiencies required. For PC 3, which accounts for approximately 25 percent of annual shipments, no original equipment manufacturers (‘‘OEMs’’) currently offer 
products that meet the efficiency level required. For PC 5, which accounts for approximately 21 percent of annual shipments, DOE estimates that seven out of 22 OEMs currently offer products that meet the efficiency level required. For PC 7, which accounts for approximately 11 percent of annual shipments, only one out of 11 OEMs currently offers products that meet the 
efficiency level required. 
At max-tech, manufacturers would 
likely need to implement all the most efficient design options in the engineering analysis. In interviews, manufacturer indicated they would redesign all product platforms and dramatically update manufacturing facilities to meet max-tech for all approximately 17.0 million annual shipments of refrigerators, refrigerator- freezers, and freezers.
9 
In particular, increased incorporation 
of VIPs could increase the expense of adapting manufacturing plants. As discussed in section IV.J.2.c of the direct final rule published elsewhere in this issue of the Federal Register, DOE expects manufacturers would likely adopt VIP technology to improve thermal insulation while minimizing loss to the interior volume for their products. Extensive incorporation of VIPs requires significant capital expenditures due to the need for more careful product handling and conveyor, increased warehousing requirements, investments in tooling necessary for the VIP installation process, and adding production line capacity to compensate for more time-intensive manufacturing associated with VIPs. Manufacturers with facilities that have limited space 
and few options to expand may consider greenfield projects. In interviews, several manufacturers expressed concerns about their ability to produce sufficient quantities of refrigerators, refrigerator-freezers, and freezers at max-tech given the required scale of investment, redesign effort, and 3-year compliance timeline. 
The Secretary tentatively concludes 
that at TSL 6 for refrigerators, refrigerator-freezers, and freezers, the benefits of energy savings, positive NPV of consumer benefits, emission reductions, and the estimated monetary value of the emissions reductions would be outweighed by the economic burden on many consumers, and the impacts on manufacturers, including the large potential reduction in INPV and the lack of manufacturers currently offering products meeting the efficiency levels required at this TSL. At TSL 6, a majority of refrigerator, refrigerator- freezer, and freezers consumers (60 percent) would experience a net cost and the average LCC savings would be negative for PC 5BI, PC 10, PC 11A, and PC 18. Additionally, manufacturers would need to make significant upfront investments to update product lines and manufacturing facilities. Manufacturers expressed concern that they would not 
be able to complete product and production line updates within the 3- year conversion period. Consequently, the Secretary has tentatively concluded that TSL 6 is not economically justified. 
DOE then considered TSL 5 for 
refrigerators, refrigerator-freezers, and freezers. For classes other than refrigerator-freezers with bottom- mounted freezers and through-the-door ice service (PC 5A), this TSL represents efficiency levels less than max-tech. TSL 5 represents similar design options as max-tech, but generally incorporates the use of high-efficiency compressors (single speed compressors or VSCs) rather than maximum efficiency VSCs, incorporates VIPs in fewer product classes, and incorporates less VIP surface area for the product classes requiring the use of VIPs as compared to TSL 6. TSL 5 would save an estimated 6.01 quads of energy, an amount DOE considers significant. Under TSL 5, the NPV of consumer benefit would be $8.64 billion using a discount rate of 7 percent, and $25.80 billion using a discount rate of 3 percent. 
The cumulative emissions reductions 
at TSL 5 are 111 Mt of CO

thousand tons of SO 2, 203 thousand 
tons of NO X, 0.24 tons of Hg, 914 
thousand tons of CH 4, and 1.10 
thousand tons of N 2O. The estimated 
monetary value of the climate benefits from reduced GHG emissions (associated with the average SC–GHG at a 3-percent discount rate) at TSL 5 is $5.87 billion. The estimated monetary value of the health benefits from reduced SO
2and NO Xemissions at TSL 
5 is $4.50 billion using a 7-percent discount rate and $11.50 billion using a 3-percent discount rate. 
Using a 7-percent discount rate for 
consumer benefits and costs, health benefits from reduced SO
2and NO X 
emissions, and the 3-percent discount rate case for climate benefits from reduced GHG emissions, the estimated 
total NPV at TSL 5 is $19.01 billion. Using a 3-percent discount rate for all benefits and costs, the estimated total NPV at TSL 5 is $43.17 billion. The estimated total NPV is provided for additional information, however DOE primarily relies upon the NPV of consumer benefits when determining whether a standard level is economically justified. 
At TSL 5, for the largest product 
classes, which are 3, 5, 5A, and 7, there is a life-cycle cost savings of $43.46, $45.47, $122.18, and $73.96 and a payback period of 5.3 years, 6.1 years, 6.0 years and 6.2 years, respectively. For these product classes, the fraction of

10For all TSLs except the Recommended TSL, the 
efficiency levels required for non-representative 
product classes are the same as the efficiency levels required for the associated directly analyzed product classes. However, as noted in section V.A of this document, the Recommended TSL from the Joint Agreement includes standard levels for some non-representative product classes that differ from their associated representative product class. Thus, in addition to the representative PC 5A, PC 7, and PC 9, the efficiency levels required for non- representative PC 9A–BI and PC 12 at the Recommended TSL also differ from the efficiency levels required at TSL 5. customers experiencing a net LCC cost 
is 34.2 percent, 39.4 percent, 39.4 percent and 42.6 percent with increases in first cost of $52.69, $69.25, $161.65, and $121.58, respectively. Overall, 33 percent of refrigerators, refrigerator- freezers, and freezers consumers would experience a net cost and the average LCC savings are positive for all product classes. 
At TSL 5, an estimated 16 percent of 
all low-income households experience a net cost, including 11 percent of low- income households with a top-mount or single-door refrigerator-freezer (represented by PC 3 and used by 72 percent of low-income households) and 32 percent of low-income households with a side-by-side refrigerator-freezer (represented by PC 7 and used by 19 percent of low-income households). More than half of low-income PC 7 consumers with a net cost experience a net cost of at least $40 and while low- income PC 7 consumers experience an average LCC savings of $132.77 at TSL 5, there are larger average LCC savings at TSL 4 ($161.87) and substantially fewer low-income PC 7 consumers would experience a net cost (0.6 percent) at that TSL. Further, the incremental increase in purchase price at TSL 5 for PC 7 is $121.58, which may be difficult for low-income homeowners to afford. 
At TSL 5, the projected change in 
INPV ranges from a decrease of $1.07 billion to a decrease of $844.2 million, which corresponds to decreases of 21.7 percent and 17.2 percent, respectively. DOE estimates that industry must invest $1.40 billion to comply with standards set at TSL 5. 
DOE estimates that approximately 14 
percent of refrigerator, refrigerator- freezer, and freezer annual shipments meet the TSL 5 efficiencies. For standard-size refrigerator-freezers, which account for approximately 70 percent of total annual shipments, approximately 1 percent of shipments meet the efficiencies required at TSL 5. 
Compared to max-tech, more manufacturers offer standard-size refrigerator-freezer products that meet the required efficiencies, however, many manufacturers do not offer products that meet this level. Of the 22 OEMs offering PC 3 products, three OEMs offer models that meet the efficiency level required. Of the 22 OEMs offering PC 5 products, 14 OEMs offer models that meet the efficiency level required. Of the 11 OEMs offering PC 7 products, only one OEM offers models that meet the efficiency level required. 
The manufacturers that do not 
currently offer models that meet TSL 5 efficiencies would need to develop new 
product platforms. Updates could include incorporating variable defrost, BLDC evaporator fan motors, and high- efficiency VSCs. Additionally, some product classes could require the use of VIPs. DOE expects manufacturers would likely need to incorporate some VIPs into PC 5 and PC 7 designs, but not to the extent required at max-tech. However, DOE expects manufacturers would need to incorporate the max-tech design options for PC 5A, which includes the use of VIPs for roughly half the cabinet surface (side walls and doors) to meet TSL 5 efficiencies. As discussed in section IV.J.2.c of the direct final rule published elsewhere in this issue of the Federal Register, the inclusion of VIPs in product design necessitates large investments in tooling and significant changes to production plants. Furthermore, given that only 1 percent of current standard-size refrigerator-freezer shipments meet TSL 5 efficiency levels, the manufacturers that are currently able to meet TSL 5 would need to scale up manufacturing capacity of compliant models. DOE anticipates conversion costs as high as $1.40 billion because the majority of product platforms in the industry would require redesign and investment. 
The Secretary tentatively concludes 
that at TSL 5 for refrigerators, refrigerator-freezers, and freezers, the benefits of energy savings, positive NPV of consumer benefits, emission 
reductions, and the estimated monetary value of the emissions reductions would be outweighed by the economic burden on consumers, particularly low-income consumers of side-by-side refrigerator- freezers, and the impacts on manufacturers, including the large potential reduction in INPV and the lack of manufacturers currently offering standard-size refrigerator-freezer products meeting the efficiency levels required at this TSL. Specifically, only one OEM currently offers any PC 7 models that meet the TSL 5 efficiencies. At TSL 5, 32 percent of low-income PC 7 consumers would experience a net cost and the incremental increase in purchase price of $121.58 may be difficult for low-income homeowners to afford. Consequently, the Secretary has tentatively concluded that TSL 5 is not economically justified. 
DOE then considered the TSL 4 which 
corresponds to the TSL recommended in the Joint Agreement (the ‘‘Recommended TSL’’). For representative product classes other than PC 5A, PC 7, and PC 9, this TSL represents the same efficiency levels as TSL 5.
10Thus, the Recommended TSL 
represents similar design options as TSL 5, except for PC 5A, PC 7, and PC 9. For PC 7, DOE expects manufacturers would not require the use of VIPs to meet the required efficiency level. For PC 5A, DOE expects manufacturers would require less VIP surface area to meet the required efficiency level. For PC 9, DOE expects manufacturers to implement variable speed compressor systems to meet required standards. DOE estimates that approximately 14 percent of annual shipments across all refrigerator, refrigerator-freezer, and freezer product classes currently meet the efficiencies required. For the Recommended TSL, DOE’s analysis utilized the January 31, 2029 (or January 31, 2030, for some product classes) compliance dates specified in the Joint Agreement. The Recommended TSL would save an estimated 5.61 quads of energy, an amount DOE considers significant. Under the Recommended TSL, the NPV of consumer benefit would be $9.04 billion using a discount rate of 7 percent, and $26.98 billion using a discount rate of 3 percent. 
The cumulative emissions reductions 
at the Recommended TSL are 101 Mt of CO
2, 31.6 thousand tons of SO 2, 186 
thousand tons of NO X, 0.22 tons of Hg, 
846.5 thousand tons of CH 4, and 0.99 
thousand tons of N 2O. The estimated 
monetary value of the climate benefits from reduced GHG emissions (associated with the average SC–GHG at a 3-percent discount rate) at the Recommended TSL is $5.02 billion. The estimated monetary value of the health benefits from reduced SO
2and NO X 
emissions at the Recommended TSL is $3.45 billion using a 7-percent discount rate and $9.80 billion using a 3-percent discount rate. 
Using a 7-percent discount rate for 
consumer benefits and costs, health benefits from reduced SO
2and NO X 
emissions, and the 3-percent discount rate case for climate benefits from reduced GHG emissions, the estimated total NPV at the Recommended TSL is $17.51 billion. Using a 3-percent discount rate for all benefits and costs, the estimated total NPV at the

Recommended TSL is $41.80 billion. 
The estimated total NPV is provided for additional information, however DOE primarily relies upon the NPV of consumer benefits when determining whether a standard level is economically justified. 
At the Recommended TSL, for the 
largest product classes, which are 3, 5, 5A, and 7, there is a life-cycle cost savings of $50.91, $55.23, $133.27, and $142.56 and a payback period of 4.8 years, 5.6 years, 4.1 years and 1.6 years, respectively. For these product classes, the fraction of customers experiencing a net LCC cost is 28.3 percent, 33.6 percent, 19.8 percent and 0.5 percent with increases in first cost of $47.67, $62.72, $81.32, and $24.39, respectively. Overall, 24.4 percent of refrigerators, refrigerator-freezers, and freezers consumers would experience a net cost and the average LCC savings are positive for all product classes. 
At the Recommended TSL, 9 percent 
of low-income households with a top- mount or single-door refrigerator-freezer (represented by PC 3 and used by 72 percent of low-income households) and 0.6 percent of low-income households with a side-by-side refrigerator-freezer (represented by PC 7 and used by 19 percent of low-income households) experience a net cost. Additionally, the incremental increase in purchase price is $24.39 for low-income PC 7 homeowners at the Recommended TSL, substantially lower than the incremental increase in purchase price of $121.58 at TSL 5. 
At the Recommended TSL, the 
projected change in INPV ranges from a decrease of $504.4 million to a decrease of $383.5 million, which correspond to decreases of 10.3 percent and 7.8 percent, respectively. DOE estimates that industry must invest $830.3 million comply with standards set at the Recommended TSL. DOE estimates that approximately 14 percent of refrigerator, refrigerator-freezer, and freezer annual shipments meet the Recommended TSL 
efficiencies. 
Compared to TSL 5, more 
manufacturers offer standard-size refrigerator freezer products that meet the required efficiencies since PC 7 has a lower required efficiency level at the Recommended TSL. For PC 7, which accounts for 11 percent of shipments, three OEMs offer products that meet the efficiency level required. Furthermore, DOE does not expect manufacturers would need to incorporate VIPs into PC 7 designs to meet the efficiencies required at the Recommended TSL. For PC 5 and PC 5A, DOE understands the two product classes often share the same production lines, with shared cabinet architecture and tooling. DOE 
expects manufacturers would likely need to incorporate some VIPs into PC 5A designs, but not to the extent required at TSL 5 and TSL 6. Thus, for the 10 OEMs that manufacture both PC 5 and PC 5A, DOE expects manufacturers could implement similar cabinet upgrades (i.e., partial VIP) for PC 
5 and PC 5A designs to achieve the efficiencies required at this level. 
For all TSLs considered in this 
proposed rule—except for the Recommended TSL—DOE is bound by the 3-year lead time requirements in EPCA when determining compliance dates (i.e., compliance with amended 
standards required in 2027). For the Recommended TSL, DOE’s analysis utilized the January 31, 2029 (or January 31, 2030, for some product classes) compliance dates specified in the Joint Agreement as they were an integral part of the multi-product joint recommendation. These compliance dates provide manufacturers the flexibility to spread capital requirements, engineering resources, and other conversion activities over a longer period of time depending on the individual needs of each manufacturer. Furthermore, these delayed compliance dates provide additional lead time and certainty for suppliers of components that improve efficiency. DOE believes the Recommended TSL mitigates risks raised by AHAM and multiple manufacturers in response to the February 2023 NOPR regarding the ability for VSC and VIP component suppliers to increase supply of these key components in the 3-year lead time required by EPCA. 
After considering the analysis and 
weighing the benefits and burdens, the Secretary has tentatively concluded that a standard set at the Recommended TSL for refrigerators, refrigerator-freezers, and freezers is economically justified. At this TSL, the average LCC savings are positive for all product classes for which an amended standard is considered. An estimated 24.4 percent of all refrigerator, refrigerator-freezer, and freezer consumers experience a net cost. An estimated 9 percent of low- income households with a top-mount or single-door refrigerator-freezer (represented by PC 3 and used by 72 percent of low-income households) and 0.6 percent of low-income households with a side-by-side refrigerator-freezer (represented by PC 7 and used by 19 percent of low-income households), experience a net cost, which is a significantly lower percentage than under TSL 5. DOE notes that for low- 
income PC 7 consumers, as well as across all PC 7 consumers, the Recommended TSL represents the 
largest average LCC savings of any TSL. The FFC national energy savings are significant and the NPV of consumer benefits is positive at the Recommended TSL using both a 3-percent and 7- percent discount rate. Notably, the benefits to consumers vastly outweigh the cost to manufacturers. At the Recommended TSL, the NPV of consumer benefits, even measured at the more conservative discount rate of 7 percent is over 17 times higher than the maximum estimated manufacturers’ loss in INPV. The standard levels at the Recommended TSL are economically justified even without weighing the estimated monetary value of emissions reductions. When those emissions reductions are included—representing $5.02 billion in climate benefits (associated with the average SC–GHG at a 3-percent discount rate), and $9.80 billion (using a 3-percent discount rate) or $3.45 billion (using a 7-percent discount rate) in health benefits—the rationale becomes stronger still. 
As stated, DOE conducts the walk- 
down analysis to determine the TSL that represents the maximum improvement in energy efficiency that is technologically feasible and economically justified as required under EPCA. DOE notes 72 percent of low- income households have a top-mount refrigerator-freezer (represented by PC 3) and that an estimated 9 percent of low- income PC 3 households experience a net cost at the Recommended TSL, whereas an estimated 6 percent of low- income households with a top-mount refrigerator-freezer experience a net cost at TSL 3. However, the average LCC savings for low-income PC 3 consumers are $22.05 higher at the Recommended TSL than at TSL 3. Further, compared to TSL 3, it is estimated that the Recommended TSL would result in additional FFC national energy savings of 0.9 quads. These additional savings and benefits at the Recommended TSL are significant. DOE considers the impacts to be, as a whole, economically justified at the Recommended TSL. 
Although DOE considered amended 
standard levels for refrigerators, refrigerator-freezers, and freezers by grouping the efficiency levels for each product class into TSLs, DOE evaluates all analyzed efficiency levels in its analysis. In general, the standard level represents the maximum energy savings that does not result in a large percentage of consumers experiencing a net LCC cost. For example, for PC 5, more than half of consumers experience a net cost at EL 3. In the case of PC 7, for which 
DOE found that a relatively higher percentage of low-income consumers

11The refrigerators, refrigerator-freezers, and 
freezers (88 FR 12452); consumer conventional 
cooking products (88 FR 6818); residential clothes washers (88 FR 13520); consumer clothes dryers (87 FR 51734); and dishwashers (88 FR 32514) utilized a 2027 compliance year for analysis at the proposed rule stage. Miscellaneous refrigeration products (88 FR 12452) utilized a 2029 compliance year for the NOPR analysis. 12AHAM has submitted written comments 
regarding cumulative regulatory burden for the other five rulemakings included in the multi- product Joint Agreement. AHAM’s written comments on cumulative regulatory burden are available at: www.regulations.gov/comment/EERE- 2020-BT-STD-0039-0031 (pp. 12–15) for

13) for consumer clothes dryers; and www.regulations.gov/comment/EERE-2019-BT-STD- 0039-0051 (pp. 21–24) for dishwashers. may experience net costs at higher 
efficiency levels, at the standard level chosen, 0.6 percent of low-income households with side-by-side refrigerator-freezers will experience a potential burden. The ELs at the standard level result in positive LCC savings for all product classes, significantly reduce the number of consumers experiencing a net cost, and reduce the decrease in INPV and conversion costs to the point where DOE has tentatively concluded they are economically justified, as discussed for the Recommended TSL in the preceding 
paragraphs. 
Therefore, based on the previous 
considerations, DOE proposes to adopt the energy conservation standards for refrigerators, refrigerator-freezers, and freezers at the Recommended TSL. 
The Recommended TSL for 
refrigerators, refrigerator-freezers, and freezers proposed in this NOPR is part of a multi-product Joint Agreement covering six rulemakings (refrigerators, refrigerator-freezers, and freezers; miscellaneous refrigeration products; conventional cooking products; residential clothes washers; consumer clothes dryers; and dishwashers). The signatories indicate that the Joint Agreement for the six rulemakings 
should be considered as a joint statement of recommended standards, to be adopted in its entirety. As discussed in section V.B.2.e of the direct final rule published elsewhere in this issue of the Federal Register, many refrigerator, refrigerator-freezer, and freezer OEMs also manufacture miscellaneous refrigeration products, conventional cooking products, residential clothes washers, consumer clothes dryers, and dishwashers. Rather than requiring compliance with five amended standards in a single year (2027),
11the 
negotiated multi-product Joint Agreement staggers the compliance dates for the five amended standards over a 4-year period (2027–2030). In response to the February 2023 NOPR, AHAM and individual manufacturers expressed concerns about the timing of ongoing home appliance rulemakings. Specifically, AHAM commented that the combination of the stringency of DOE’s proposals, the short lead-in time required under EPCA to comply with standards, and the overlapping timeframe of multiple standards affecting the same manufacturers represents significant cumulative 
regulatory burden for the home appliance industry. (AHAM, No. 69 at 
pp. 20–21) AHAM has submitted similar comments to other ongoing consumer product rulemakings.
12As AHAM is a 
key signatory of the Joint Agreement, DOE understands that the compliance dates recommended in the Joint Agreement would help reduce cumulative regulatory burden. These compliance dates help relieve concern 
on the part of some manufacturers about their ability to allocate sufficient resources to comply with multiple concurrent amended standards, about the need to align compliance dates for products that are typically designed or sold as matched pairs, and about the ability of their suppliers to ramp up production of key components. The Joint Agreement also provides additional years of regulatory certainty for manufacturers and their suppliers while still achieving the maximum improvement in energy efficiency that is technologically feasible and economically justified. 
The proposed energy conservation 
standards for refrigerators, refrigerator- freezers, and freezers, which are expressed in kWh/yr, are shown in Table III.3 and Table IIII.4.

B. Annualized Benefits and Costs of the 
Proposed Standards 
The benefits and costs of the proposed 
standards can also be expressed in terms 
of annualized values. The annualized net benefit is (1) the annualized national economic value (expressed in 2022$) of the benefits from operating products that meet the proposed standards (consisting primarily of operating cost savings from using less energy), minus increases in product purchase costs, and (2) the annualized monetary value of the climate and health benefits from emission reductions. Table III.5 shows the annualized 
values for refrigerators, refrigerator- 
freezers, and freezers under the Recommended TSL, expressed in 2022$. The results under the primary estimate are as follows. 
Using a 7-percent discount rate for 
consumer benefits and costs and health benefits from reduced NO
Xand SO 2 
emissions, and the 3-percent discount rate case for climate benefits from reduced GHG emissions, the estimated cost of the proposed standards is $590.5 million per year in increased equipment costs, while the estimated annual monetized benefits are $1.7 billion in reduced equipment operating costs, $303.8 million in climate benefits, and $410.6 million in health benefits. In this case, the net benefit would amount to $1.8 billion per year. 
Using a 3-percent discount rate for all 
benefits and costs, the estimated cost of the proposed standards is $567.5 million per year in increased equipment costs, while the estimated annual monetized benefits are $2.2 billion in reduced operating costs, $303.8 million in climate benefits, and $592.9 million in health benefits. In this case, the net benefit would amount to $2.5 billion per year.

Note: This table presents the costs and benefits associated with refrigerators, refrigerator-freezers, and freezers shipped during the period 
2029–2058 for the product classes listed in Table III.3 and shipped in 2030–2059 for the product classes listed in Table IIII.4. These results in-
clude benefits which accrue after 2058/9 from the products shipped in 2029–2058 for the product classes listed in Table III.3 and shipped in 2030–2059 for the product classes listed in Table IIII.4. The Primary, Low Net Benefits, and High Net Benefits Estimates utilize projections of en-ergy prices from the AEO2023 Reference case, Low Economic Growth case, and High Economic Growth case, respectively. In addition, incre-
mental equipment costs reflect a medium decline rate in the Primary Estimate, a low decline rate in the Low Net Benefits Estimate, and a high decline rate in the High Net Benefits Estimate. The methods used to derive projected price trends are explained in sections V.H.3 of the direct final rule published elsewhere in this issue of the Federal Register. Note that the Benefits and Costs may not sum to the Net Benefits due to rounding.

* Climate benefits are calculated using four different estimates of the SC–CO 2, SC–CH 4and SC–N 2O. For presentational purposes of this 
table, the climate benefits associated with the average SC–GHG at a 3 percent discount rate are shown, but DOE does not have a single central 
SC–GHG point estimate, and it emphasizes the importance and value of considering the benefits calculated using all four sets of SC–GHG esti-mates. To monetize the benefits of reducing GHG emissions, this analysis uses the interim estimates presented in the Technical Support Docu-
ment: Social Cost of Carbon, Methane, and Nitrous Oxide Interim Estimates Under Executive Order 13990 published in February 2021 by the 
IWG. 
** Health benefits are calculated using benefit-per-ton values for NO
Xand SO 2. DOE is currently only monetizing (for SO 2and NO X) PM 2.5 
precursor health benefits and (for NO X) ozone precursor health benefits, but will continue to assess the ability to monetize other effects such as 
health benefits from reductions in direct PM 2.5emissions. See section IV.L of the direct final rule published elsewhere in this issue of the Federal 
Register for more details. 
† Total benefits for both the 3-percent and 7-percent cases are presented using the average SC–GHG with 3-percent discount rate, but DOE 
does not have a single central SC–GHG point estimate. 
‡‡Operating Cost Savings are calculated based on the life cycle costs analysis and national impact analysis as discussed in detail below. See 
sections IV.F and IV.H of the direct final rule published elsewhere in this issue of the Federal Register. DOE’s national impacts analysis in-
cludes all impacts (both costs and benefits) along the distribution chain beginning with the increased costs to the manufacturer to manufacture the product and ending with the increase in price experienced by the consumer. DOE also separately conducts a detailed analysis on the im-pacts on manufacturers (i.e., manufacturer impact analysis, or ‘‘MIA’’). See section IV.J of the direct final rule published elsewhere in this issue of 
the Federal Register. In the detailed MIA, DOE models manufacturers’ pricing decisions based on assumptions regarding investments, conver-
sion costs, cashflow, and margins. The MIA produces a range of impacts, which is the rule’s expected impact on the INPV. The change in INPV is the present value of all changes in industry cash flow, including changes in production costs, capital expenditures, and manufacturer profit margins. The annualized change in INPV is calculated using the industry weighted average cost of capital value of 9.1 percent that is estimated in the manufacturer impact analysis (see chapter 12 of the direct final rule TSD for a complete description of the industry weighted average cost 
of capital). For refrigerators, refrigerator-freezers, and freezers, the annualized change in INPV ranges from ¥$48.7 million to ¥$37.0 million. 
DOE accounts for that range of likely impacts in analyzing whether a trial standard level is economically justified. See section V.C of the direct 
final rule published elsewhere in this issue of the Federal Register. DOE is presenting the range of impacts to the INPV under two manufacturer markup scenarios: the Preservation of Gross Margin scenario, which is the manufacturer markup scenario used in the calculation of Consumer Operating Cost Savings in this table; and the Preservation of Operating Profit scenario, where DOE assumed manufacturers would not be able to increase per-unit operating profit in proportion to increases in manufacturer production costs. DOE includes the range of estimated annual change in INPV in the above table, drawing on the MIA explained further in section IV.J of the direct final rule published elsewhere in this issue of the Federal Register to provide additional context for assessing the estimated impacts of this proposal to society, including potential changes in production and consumption, which is consistent with OMB’s Circular A–4 and E.O. 12866. If DOE were to include the INPV into the annualized net benefit calculation for this proposed rule, the annualized net benefits would range from $2,480.9 million to $2,492.6 million at 3- percent discount rate and would range from $1,742.2 million to $1,753.9 million at 7-percent discount rate.

V. Procedural Issues and Regulatory Review 
The regulatory reviews conducted for 
this proposed rule are identical to those conducted for the direct final rule published elsewhere in this issue of the Federal Register. Please see the direct final rule for further details. 
A. Review Under the Regulatory 
Flexibility Act 
The Regulatory Flexibility Act (5 
U.S.C. 601 et seq.) requires preparation of an initial regulatory flexibility analysis (‘‘IRFA’’) and a final regulatory flexibility analysis (‘‘FRFA’’) for any rule that by law must be proposed for public comment, unless the agency certifies that the rule, if promulgated, will not have a significant economic impact on a substantial number of small entities. As required by E.O. 13272, ‘‘Proper Consideration of Small Entities in Agency Rulemaking,’’ 67 FR 53461 (Aug. 16, 2002), DOE published procedures and policies on February 19, 2003, to ensure that the potential impacts of its rules on small entities are properly considered during the rulemaking process. 68 FR 7990. DOE has made its procedures and policies available on the Office of the General Counsel’s website (www.energy.gov/gc/ 
office-general-counsel). DOE has prepared the following IRFA for the products that are the subject of this proposed rulemaking. 
For manufacturers of refrigerators, 
refrigerator-freezers, and freezers, the Small Business Administration (‘‘SBA’’) has set a size threshold, which defines those entities classified as ‘‘small businesses’’ for the purposes of the statute. DOE used the SBA’s small business size standards to determine whether any small entities would be subject to the requirements of the rule. (See 13 CFR part 121.) The size 
standards are listed by North American Industry Classification System (‘‘NAICS’’) code and industry description and are available at www.sba.gov/document/support--table- size-standards. Manufacturing of 
refrigerators, refrigerator-freezers, and freezers is classified under NAICS 335220, ‘‘Major Household Appliance Manufacturing.’’ The SBA sets a threshold of 1,500 employees or fewer for an entity to be considered as a small business for this category. 
1. Description of Reasons Why Action Is 
Being Considered 
DOE is proposing amended energy 
conservation standards for refrigerators, refrigerator-freezers, and freezers. EPCA prescribed energy conservation standards for these products (42 U.S.C. 6295(b)(1)–(2)), and directed DOE to conduct three cycles of future rulemakings to whether to amend these standards. (42 U.S.C. 6295(b)(3)(A)(i), 
(b)(3)(B), and (b)(4)). DOE has completed these rulemakings. EPCA further provides that, not later than 6 years after the issuance of any final rule establishing or amending a standard, DOE must publish either a notice of determination that standards for the product do not need to be amended, or a NOPR including new proposed energy conservation standards (proceeding to a final rule, as appropriate). (42 U.S.C. 6295(m)(1)) 
Pursuant to EPCA, any new or 
amended energy conservation standard must be designed to achieve the maximum improvement in energy efficiency that DOE determines is technologically feasible and economically justified. (42 U.S.C. 6295(o)(2)(A)) Furthermore, the new or amended standard must result in significant conservation of energy. (42 U.S.C. 6295(o)(3)(B)) 
In light of the above and the 
requirements under 42 U.S.C. 6295(p)(4)(A)–(B), DOE is issuing this NOPR proposing energy conservation standards for refrigerators, refrigerator- freezers, and freezers. These standard 
levels were submitted jointly to DOE on September 25, 2023, by groups representing manufacturers, energy and environmental advocates, consumer groups, and a utility.
13This letter, titled 
‘‘Energy Efficiency Agreement of 2023’’ 
(hereafter, the ‘‘Joint Agreement’’14), 
recommends specific energy 
conservation standards for refrigerators, refrigerator-freezers, and freezers that, in the commenters’ view, would satisfy the EPCA requirements in 42 U.S.C. 6295(o). 
2. Objectives of, and Legal Basis for, 
Rule 
EPCA authorizes DOE to regulate the 
energy efficiency of a number of consumer products and certain industrial equipment. Title III, Part B of EPCA established the Energy Conservation Program for Consumer Products Other Than Automobiles. These products include refrigerators, refrigerator-freezers, and freezers, the subject of this document. (42 U.S.C. 6292(a)(1)) EPCA prescribed energy conservation standards for these products (42 U.S.C. 6295(b)(1)–(2)), and directed. DOE to conduct three cycles of 
future rulemakings to whether to amend these standards. (42 U.S.C. 6295(b)(3)(A)(i), (b)(3)(B), and (b)(4)). DOE has completed these rulemakings. EPCA further provides that, not later than 6 years after the issuance of any final rule establishing or amending a standard, DOE must publish either a notice of determination that standards for the product do not need to be amended, or a NOPR including new proposed energy conservation standards (proceeding to a final rule, as appropriate).

Small Entities Regulated
DOE reviewed this proposed rule 
under the provisions of the Regulatory Flexibility Act and the procedures and policies published on February 19, 2003. 68 FR 7990. DOE conducted a market survey to identify potential small manufacturers of refrigerators, refrigerator-freezers, and freezers. DOE conducted a market survey to identify potential small manufacturers of refrigerators, refrigerator-freezers, and freezers. DOE began its assessment by reviewing DOE’s Compliance Certification Database,
15California 
Energy Commission’s Modernized Appliance Efficiency Database System,
16individual company websites, 
and prior refrigerator, refrigerator- freezer, and freezer rulemakings to identify manufacturers of the covered product. DOE then consulted publicly available data, such as manufacturer websites, manufacturer specifications and product literature, import/export logs (e.g., bills of lading from Panjiva
17), 
and basic model numbers, to identify OEMs of covered refrigerators, refrigerator-freezers, and freezers. DOE further relied on public data and subscription-based market research tools (e.g., Dun & Bradstreet reports
18) 
to determine company, location, headcount, and annual revenue. DOE also asked industry representatives if they were aware of any small manufacturers during manufacturer interviews in support of the February 2023 NOPR. 88 FR 12452. DOE screened out companies that do not offer products covered by this rulemaking, do not meet the SBA’s definition of a 
‘‘small business,’’ or are foreign-owned and operated. 
DOE identified 63 OEMs that sell 
refrigerators, refrigerator-freezers, or freezers in the United States. Of the 63 OEMs identified, DOE tentatively determined that one company qualifies as a small business and is not foreign- owned and operated. 
In support of the February 2023 
NOPR, DOE reached out to the small business and invited them to participate in a voluntary interview. The small 
business did not consent to participate in a formal MIA interview. DOE also requested information about small businesses and potential impacts on small businesses while interviewing larger manufacturers. 
4. Description and Estimate of
Compliance Requirements IncludingDifferences in Cost, if Any, for DifferentGroups of Small Entities
The one small business identified has 
45 refrigerator, refrigerator-freezer, and 
freezer models certified in DOE’s Compliance Certification Database (‘‘CCD’’). Of those 45 models, 43 models are compact-size refrigerators, refrigerator-freezers, or freezers (34 PC 13A models, three PC 15 models, and six PC 17 models). The remaining two models are standard-size built-in refrigerator-freezer models (PC 3A–BI). Of the 34 PC 13A models, 22 models meet the efficiency required (EL 1) at TSL. For PC 15, PC 17, and PC 3A–BI, this small manufacturer only offers models at the current DOE baseline efficiency and, therefore, does not offer any products that meet the proposed TSL efficiencies (i.e., 10-percent 
reduction in energy use from the current DOE baseline). To meet the required efficiencies, DOE expects this small manufacturer would likely need to implement variable defrost and higher efficiency compressors across their product platforms. For some PC 3A–BI, PC 13A, PC 15, and PC 17 models, variable-speed compressors may be necessary to meet the required efficiencies. Some capital conversion costs may be necessary for additional tooling and new stations to test more variable-speed compressors. Product conversion costs may be necessary for developing, qualifying, sourcing, and testing new components. DOE estimated conversion costs for this small manufacturer by using model counts to scale down the industry conversion costs. DOE estimates that the small manufacturer may incur $367,000 in capital conversion costs and $530,000 in product conversion costs related to redesigning their products to meet amended standards. Based on subscription-based market research reports, the small business has an annual revenue of approximately $85.3 million. The total conversion costs of $897,000 are approximately 0.2 percent of company revenue over the 5-year conversion period. 5. Duplication, Overlap, and Conflict
With Other Rules and Regulations
DOE is not aware of any rules or 
regulations that duplicate, overlap, or conflict with the proposed rule. 
6. Significant Alternatives to the Rule
The discussion in the previous
section analyzes impacts on small 
businesses that would result from DOE’s proposed rule, represented by TSL 4 (i.e., the Recommended TSL). In 
reviewing alternatives to the proposed rule, DOE examined energy conservation standards set at lower efficiency levels. While TSLs 3, 2, and 1 would reduce the impacts on small business manufacturers, it would come at the expense of a reduction in energy savings. TSL 1 achieves 51 percent lower energy savings compared to the energy savings at TSL 4. TSL 2 achieves 40 percent lower energy savings compared to the energy savings at TSL 4. TSL 3 achieves 16 percent lowerenergy savings compared to the energysavings at TSL 4.
Based on the presented discussion, 
establishing standards at TSL 4 balances the benefits of the energy savings at TSL 4 with the potential burdens placed on refrigerators, refrigerator-freezers, and freezers manufacturers, including small business manufacturers. Accordingly, DOE does not propose one of the other TSLs considered in the analysis, or the other policy alternatives examined as part of the regulatory impact analysis and included in chapter 17 of the direct final rule TSD. 
Additional compliance flexibilities 
may be available through other means. EPCA provides that a manufacturer whose annual gross revenue from all of its operations does not exceed $8 million may apply for an exemption from all or part of an energy conservation standard for a period not longer than 24 months after the effective date of a final rule establishing the standard. (42 U.S.C. 6295(t)) Additionally, manufacturers subject to DOE’s energy efficiency standards may apply to DOE’s Office of Hearings and Appeals for exception relief under certain circumstances. Manufacturers should refer to 10 CFR part 430, subpart E, and 10 CFR part 1003 for additional details.

continues to read as follows: 
Authority: 42 U.S.C. 6291–6309; 28 U.S.C. 
2461 note. 
■2. Amend appendix A to subpart B of 
part 430 by: 
■a. In section 1: 
■i. In paragraph (b)(i), removing the 
text ‘‘5.3(e)’’ and adding in its place the text ‘‘5.5’’; and 
■ii. Removing the undesignated 
paragraph immediately following paragraph (b)(ii); 
■b. In section 3, adding, in alphabetical 
order, definitions for ‘‘Door-in-door’’ and ‘‘Transparent door’’; ■c. In section 5.3: 
■i. Removing paragraphs (a) and (f); 
and 
■ii. Redesignating paragraphs (b) 
through (e) as paragraphs (a) through (d); and

The additions read as follows: 
Appendix A to Subpart B of Part 430— Uniform Test Method for Measuring the Energy Consumption of Refrigerators, Refrigerator-Freezers, and Miscellaneous Refrigeration Products 
* * * * * 
3. * * * 
Door-in-door means a set of doors or an 
outer door and inner drawer for which— 
(a) Both doors (or both the door and the 
drawer) must be opened to provide access to the interior through a single opening; 
(b) Gaskets for both doors (or both the door 
and the drawer) are exposed to external ambient conditions on the outside around the full perimeter of the respective openings; and 
(c) The space between the two doors (or 
between the door and the drawer) achieves temperature levels consistent with the temperature requirements of the interior compartment to which the door-in-door provides access. 
* * * * * 
Transparent door means an external fresh 
food compartment door which meets the following criteria: 
(a) The area of the transparent portion of 
the door is at least 40 percent of the area of the door. 
(b) The area of the door is at least 50 
percent of the sum of the areas of all the external doors providing access to the fresh food compartments and cooler compartments. 
(c) For the purposes of this evaluation, the 
area of a door is determined as the product of the maximum height and maximum width dimensions of the door, not considering potential extension of flaps used to provide a seal to adjacent doors.
