Energy Conservation Program: Energy 
Conservation Standards for Refrigerators, Refrigerator-Freezers, and Freezers 
AGENCY : Office of Energy Efficiency and 
Renewable Energy, Department of Energy. 
ACTION : Direct final rule. 
SUMMARY : The Energy Policy and 
Conservation Act, as amended (‘‘EPCA’’), prescribes energy conservation standards for various consumer products and certain commercial and industrial equipment, including refrigerators, refrigerator- freezers, and freezers. In this direct final rule, the U.S. Department of Energy (‘‘DOE’’) is adopting amended energy conservation standards for refrigerators, refrigerator-freezers, and freezers. DOE has determined that the amended energy conservation standards for these products would result in significant conservation of energy, and are technologically feasible and economically justified. 
DATES : The effective date of this rule is 
May 16, 2024. The incorporation by reference of certain material listed in the rule was approved by the Director as of May 21, 2014, and November 12, 2021. If adverse comments are received by May 6, 2024, and DOE determines that such comments may provide a reasonable basis for withdrawal of the direct final rule under 42 U.S.C. 6295(o), a timely withdrawal of this rule will be published in the Federal Register. If no such adverse comments are received, compliance with the amended standards established for refrigerators, refrigerator-freezers, and freezers in this direct final rule is required on and after January 31, 2029, for the product classes listed in Table I.1 and January 31, 2030, for the product classes listed in Table I.2. 
ADDRESSES : The docket for this 
rulemaking, which includes Federal Register notices, public meeting 
attendee lists and transcripts, comments, and other supporting documents/materials, is available for review at www.regulations.gov. All

I. Synopsis of the Direct Final 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 direct final rule. (42 U.S.C. 6292(a)(7)) 
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 issuing this direct final rule amending energy conservation standards for refrigerators, refrigerator- freezers, and freezers. 
The adopted standard levels in this 
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’’),
3recommends 
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). DOE subsequently received letters of support from states including California, Massachusetts, and New York
4and 
utilities including San Diego Gas and Electric (‘‘SDG&E’’) and Southern California Edison (‘‘SCE’’)
5advocating 
for the adoption of the recommended standards and a follow-up letter from the parties to the Joint Agreement that more specifically described the recommended standards for refrigerators, refrigerator-freezers, and freezers, and their rationale for entering 
into a negotiation to develop them.
6 
In accordance with the direct final 
rule provisions at 42 U.S.C. 6295(p)(4), DOE has determined that the recommendations contained in the Joint Agreement are compliant with 42 U.S.C. 6295(o). As required by 42 U.S.C. 6295(p)(4)(A)(i), DOE is also simultaneously publishing a notice of proposed rulemaking (‘‘NOPR’’) that contains identical standards to those adopted in this direct final rule. Consistent with the statute, DOE is providing a 110-day public comment period on the direct final rule. (42 U.S.C. 6295(p)(4)(B)) If DOE determines that any comments received provide a reasonable basis for withdrawal of the direct final rule under 42 U.S.C. 6295(o) or any other applicable law, DOE will publish the reasons for withdrawal and continue the rulemaking under the NOPR. (42 U.S.C. 6295(p)(4)(C)) See section II.A of this document for more details on DOE’s statutory authority. 
The amended standards that DOE is 
adopting in this direct final rule are the efficiency levels recommended in the Joint Agreement (shown in Tables I.1 and I.2) expressed in terms of kilowatt hours per year (‘‘kWh/yr’’) as measured according to DOE’s current refrigerator, refrigerator-freezer, and freezer test procedures codified at title 10 of the Code of Federal Regulations (‘‘CFR’’), part 430, subpart B, appendices A (‘‘appendix A’’) and B (‘‘appendix B’’). 
The amended standards 
recommended in the Joint Agreement are represented as trial standard level (‘‘TSL’’) 4 in this document (hereinafter the ‘‘Recommended TSL’’) and are described in section V.A of this document. 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.

are affected by a standard and are measured relative 
to the efficiency distribution in the no-new- standards case, which depicts the market in the compliance year in the absence of new or amended 
standards (see section IV.F.9 of this document). The 
simple PBP, which is designed to compare specific 
efficiency levels, is measured relative to the baseline product (see section IV.C of this

A. Benefits and Costs to Consumers 
Table I.3 summarizes DOE’s 
evaluation of the economic impacts of 
the adopted standards on consumers of 
refrigerators, refrigerator-freezers, and freezers, as measured by the average 
life-cycle cost (‘‘LCC’’) savings and the simple payback period (‘‘PBP’’).
7The 
average LCC savings are positive for all product classes for which a standard is proposed, and the PBP is less than the average lifetime of refrigerators, refrigerator-freezers, and freezers, which varies by product class (see section 
IV.F.7 of this document).

8All monetary values in this document are 
expressed in 2022 dollars. 
9DOE’s analysis period extends 30-years from the 
compliance year. The analysis period ranges from 
2023–2056 for the no-new-standards case and all TSLs, except for TSL 4 (the Recommended TSL). The analysis period for TSL 4 ranges from 2023– 2058 for the product classes listed in Table I.1 and 2023–2059 for the product classes listed in Table I.2. 
10The no-new-standards case INPV of $4.91 
billion reflects the sum of discounted free cash flows from 2023–2056 (from direct final rule publication to 30 years from the 2027 compliance date) plus a discounted terminal value. 11The quantity refers to full-fuel-cycle (‘‘FFC’’) 
energy savings. FFC energy savings includes the energy consumed in extracting, processing, and transporting primary fuels (i.e., coal, natural gas, 
petroleum fuels), and, thus, presents a more complete picture of the impacts of energy efficiency standards. For more information on the FFC metric, see section of this document. 
12A metric ton is equivalent to 1.1 short tons. 
Results for emissions other than CO 2are presented 
in short tons. 13DOE calculated emissions reductions relative 
to the no-new-standards-case, which reflects key assumptions in the Annual Energy Outlook 2023 (‘‘AEO2023’’). AEO2023 represents current Federal 
and State legislation and final implementation of regulations as of the time of its preparation. See section IV.K of this document for further discussion of AEO2023 assumptions that affect air pollutant

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 IWG (‘‘February 2021 SC–GHG TSD’’). www.whitehouse.gov/wp- content/uploads/2021/02/TechnicalSupportDocument_SocialCostofCarbonMethaneNitrousOxide.pdf.

DOE’s analysis of the impacts of the 
adopted standards on consumers is 
described in section IV.F of this document. 
B. Impact on Manufacturers
8 
The industry net present value 
(‘‘INPV’’) is the sum of the discounted 
cash flows to the industry from the base year (2023) through the end of the analysis period, which is 30 years from the analyzed compliance date.
9Using a 
real discount rate of 9.1 percent, DOE estimates that the INPV for manufacturers of refrigerators, refrigerator-freezers, and freezers in the case without amended standards is $4.91 billion.
10Under the adopted 
standards, which align with the Recommended TSL for refrigerators, refrigerator-freezers, and freezers, DOE estimates the change in INPV to range from ¥10.3 percent to ¥7.8 percent, 
which is approximately ¥$504.4 million to ¥$383.5 million. In order to bring products into compliance with amended standards, it is estimated that industry will incur total conversion costs of $830.3 million. 
DOE’s analysis of the impacts of the 
adopted standards on manufacturers is described in sections IV.J and V.B.2 of this document. 
C. National Benefits and Costs 
DOE’s analyses indicate that the 
adopted energy conservation standards 
for refrigerators, refrigerator-freezers, and freezers would save a significant amount of energy. Relative to the case without amended standards, the lifetime energy savings for refrigerators, refrigerator-freezers, and freezers purchased in the 30-year period that begins in the anticipated year of compliance with amended standards (2029–2058 for the product classes listed in Table I.1 and 2030–2059 for the product classes listed in Table I.2), amount to 5.6 quadrillion British thermal units (‘‘Btu’’), or quads.
11This 
represents a savings of 11 percent relative to the energy use of these products in the case without amended standards (referred to as the ‘‘no-new- standards case’’). 
The cumulative net present value 
(‘‘NPV’’) of total consumer benefits of the standards for refrigerators, refrigerator-freezers, and freezers ranges from $9.0 billion (at a 7-percent discount rate) to $27.0 billion (at a 3- percent discount rate). This NPV expresses the estimated total value of future operating cost savings minus the estimated increased product costs for refrigerators, refrigerator-freezers, and freezers purchased in 2029–2058 for the product classes listed in Table I.1 and 2030–2059 for the product classes listed in Table I.2. 
In addition, the adopted standards for 
refrigerators, refrigerator-freezers, and freezers are projected to yield significant environmental benefits. DOE estimates that the standards will result in cumulative emission reductions (over the same period as for energy savings) of 100.8 million metric tons (‘‘Mt’’)
12of 
carbon dioxide (‘‘CO 2’’), 31.6 thousand 
tons of sulfur dioxide (‘‘SO 2’’), 186.1 
thousand tons of nitrogen oxides (‘‘NO
X’’), 846.5 thousand tons of methane (‘‘CH 4’’), 1.0 thousand tons of 
nitrous oxide (‘‘N 2O’’), and 0.2 tons of 
mercury (‘‘Hg’’).13 
DOE estimates the value of climate 
benefits from a reduction in greenhouse 
gases (‘‘GHG’’) using four different estimates of the social cost of CO
2(‘‘SC– 
CO 2’’), the social cost of methane (‘‘SC– 
CH 4’’), and the social cost of nitrous 
oxide (‘‘SC–N 2O’’). Together these 
represent the social cost of GHG (‘‘SC– 
GHG’’). DOE used interim SC–GHG values developed by an Interagency Working Group on the Social Cost of Greenhouse Gases (‘‘IWG’’).
14The 
derivation of these values is discussed in section IV.L of this document. For presentational purposes, the climate benefits associated with the average SC– GHG at a 3-percent discount rate are estimated to be $5.0 billion. 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 estimates. 
DOE estimated the monetary health 
benefits of SO
2and NO Xemissions 
reductions, using benefit-per-ton estimates from the scientific literature, as discussed in section IV.L of this document. DOE estimated the present value of the health benefits would be $3.4 billion using a 7-percent discount rate, and $9.8 billion using a 3-percent

from the amended standards for refrigerators, refrigerator-freezers, and freezers. There are other important unquantified effects, including certain unquantified climate benefits, unquantified public health benefits from the reduction of toxic air pollutants and other emissions, unquantified energy security benefits, and distributional effects, among others.

Note: This table presents present value (in 2022$) of the costs and benefits associated with refrigerators, refrigerator-freezers, and freezers 
shipped in 2029–2058 for the product classes listed in Table I.1 and shipped in 2030–2059 for the product classes listed in Table I.2. These re-
sults include benefits which accrue after 2058/9 from the products shipped in 2029/30–2058/9. 
* Climate benefits are calculated using four different estimates of the social cost of carbon (SC–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 discount rate) ( see section IV.L of 
this document). Together these represent the global SC–GHG. For presentational purposes of this table, the climate benefits associated with the average 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 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 2.5pre-
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. See section IV.L of this document for more details. 
† Total and net benefits include those consumer, climate, and health benefits that can be quantified and monetized. For presentation purposes, 
total and net 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. DOE emphasizes the importance and value of considering the benefits c alculated 
using all four sets of SC–GHG estimates. 
‡‡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 this document. DOE’s national impact analysis (‘‘NIA’’) includes all impacts (both costs and benefits) along the distribu-tion 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 impacts on manufacturers (the MIA). See section IV.J of this docu-
ment. In the detailed MIA, DOE models manufacturers’ pricing decisions based on assumptions regarding investments, conversion c osts, 
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. Change in INPV is calculated using the industry weighted average cost of capital value of 9.1 percent that is estimated in the manufacturer im-pact analysis (see chapter 12 of the direct final rule technical support document (‘‘TSD’’) for a complete description of the industry weighted av er-
age cost of capital). For refrigerators, refrigerator-freezers, and freezers, those values are ¥$504 million to ¥$383 million. DOE accounts for 
that range of likely impacts in analyzing whether a TSL is economically justified. See section V.C of this document. DOE is presenting the range 
of impacts to the INPV under two 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 as-sumed manufacturers would not be able to increase per-unit operating profit in proportion to increases in manufacturer production costs. DOE in-cludes the range of estimated INPV in the above table, drawing on the MIA explained further in section IV.J of this document, to provide addi-tional context for assessing the estimated impacts of this direct final rule 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 net benefit calculation for this direct final rule, the net benefits would range from $41.3 billion to $41.4 billion at 3-percent discount rate and would range from $17.0 billion to $17.1 billion at 7-percent discount rate. Parentheses ( ) indicate negative values.

16To convert the time-series of costs and benefits 
into annualized values, DOE calculated a present 
value in 2022, the year used for discounting the NPV of total consumer costs and savings. For the benefits, DOE calculated a present value associated with each year’s shipments in the year in which the shipments occur (e.g., 2020 or 2030), and then 
discounted the present value from each year to 2022. Using the present value, DOE then calculated the fixed annual payment over a 30-year period, starting in the compliance year, that yields the same present value. The benefits and costs of the proposed 
standards can also be expressed in terms 
of annualized values. The monetary values for the total annualized net benefits are (1) the reduced consumer operating costs, minus (2) the increase in product purchase prices and installation costs, plus (3) the value of climate and health benefits of emission reductions, all annualized.
16 
The national operating cost savings 
are domestic private U.S. consumer monetary savings that occur as a result of purchasing the covered products and are measured for the lifetime of refrigerators, refrigerator-freezers, and 
freezers shipped in 2029–2058 for the product classes listed in Table I.1 and shipped in 2030–2059 for the product classes listed in Table I.2. The benefits associated with reduced emissions achieved as a result of the adopted standards are also calculated based on 
the lifetime of refrigerators, refrigerator- freezers, and freezers shipped in 2029– 2058 for the product classes listed in Table I.1 and shipped in 2030–2059 for the product classes listed in Table I.2. Total benefits for both the 3-percent and 7-percent cases are presented using the average GHG social costs with 3-percent discount rate. Estimates of SC–GHG values are presented for all four discount rates in section IV.L of this document. 
Table I.5 presents the total estimated 
monetized benefits and costs associated with the proposed standard, expressed in terms of annualized values. 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 standards adopted in this rule 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 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.

Parentheses ( ) indicate negative values. 
DOE’s analysis of the national impacts 
of the adopted standards is described in 
sections IV.H, IV.K, and IV.L of this document. 
D. Conclusion 
DOE has determined that the Joint 
Agreement was submitted jointly by 
interested persons that are fairly representative of relevant points of view, in accordance with 42 U.S.C. 6295(p)(4)(A). After considering the recommended standards and weighing the benefits and burdens, DOE has determined that the recommended standards are in accordance with 42 U.S.C. 6295(o), which contains the criteria for prescribing new or amended standards. Specifically, the Secretary has determined that the adoption of the recommended standards would result in the significant conservation of energy and is the maximum improvement in energy efficiency that is technologically feasible and economically justified. In determining whether the recommended standards are economically justified, the Secretary has determined that the benefits of the recommended standards exceed the burdens. The Secretary has further concluded that the recommended standards, when considering the benefits of energy savings, positive NPV of consumer benefits, emission reductions, the estimated monetary value of the emissions reductions, and positive average LCC savings, would yield benefits that outweigh the negative impacts on some consumers and on manufacturers, including the conversion costs that could result in a reduction in INPV for manufacturers. 
Using a 7-percent discount rate for 
consumer benefits and costs and NO
X 
and SO 2reduction benefits, and a 3- 
percent discount rate case for GHG social costs, the estimated cost of the 
standards for refrigerators, refrigerator- freezers, and freezers is $590.5 million per year in increased product costs, while the estimated annual monetized benefits are $1.7 billion in reduced product operating costs, $303.8 million in climate benefits, and $410.6 million in health benefits. The net monetized benefit amounts to $1.8 billion per year. 
The significance of energy savings 
offered by a new or amended energy conservation standard cannot be determined without knowledge of the specific circumstances surrounding a given rulemaking.
17For example, some 
covered products and equipment have most of their energy consumption occur during periods of peak energy demand. The impacts of these products on the energy infrastructure can be more pronounced than products with relatively constant demand. Accordingly, DOE evaluates the significance of energy savings on a case- by-case basis. 
As previously mentioned, the 
standards are projected to result in estimated national energy savings of 5.6 
quads (full-fuel cycle (‘‘FFC’’)), the equivalent of the primary annual energy use of 37 million homes. In addition, they are projected to reduce CO
2 
emissions by 100.8 Mt. Based on these findings, DOE has determined the energy savings from the standard levels adopted in this direct final rule are ‘‘significant’’ within the meaning of 42 U.S.C. 6295(o)(3)(B). A more detailed discussion of the basis for these conclusions is contained in the remainder of this document and the accompanying TSD.
18 
Under the authority provided by 42 
U.S.C. 6295(p)(4), DOE is issuing this direct final rule amending the energy conservation standards for refrigerators, refrigerator-freezers, and freezers. Consistent with this authority, DOE is also simultaneously publishing elsewhere in this Federal Register a NOPR proposing standards that are identical to those contained in this direct final rule. See 42 U.S.C. 6295(p)(4)(A)(i). 
II. Introduction 
The following section briefly 
discusses the statutory authority 
underlying this direct final 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 directed 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 
VerDate Sep<11>2014 19:16 Jan 16, 2024 Jkt 262001 PO 00000 Frm 00009 Fmt 4701 Sfmt 4700 E:\FR\FM\17JAR2.SGM 17JAR2lotter on DSK11XQN23PROD with RULES23034 Federal Register / Vol. 89, No. 11 / Wednesday, January 17, 2024 / Rules and Regulations 
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 in limited instances 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 42 U.S.C. 6295(Ir)) 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 10 CFR part 430, subpart B, appendix A, Uniform Test Method for Measuring the Energy Consumption of Refrigerators, Refrigerator-Freezers, and Miscellaneous Refrigeration Products (‘‘appendix A’’), and appendix B, Uniform Test Method for Measuring the Energy Consumption of Freezers (‘‘appendix B’’). 
DOE must follow specific statutory 
criteria for prescribing new or amended standards for covered products, including refrigerators, refrigerator- freezers, and freezers. 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) and 42 U.S.C. 6295(o)(3)(B)) Furthermore, DOE may not adopt any standard that would not result in the significant conservation of energy. (42 U.S.C. 6295(o)(3)(B)) 
Moreover, DOE may not prescribe a 
standard (1) for certain products, including refrigerators, refrigerator- 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)) 
Further, EPCA, as codified, 
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. A rule prescribing an energy conservation standard for a type (or class) of product must specify a different standard level for a type or class of products 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 consider such factors as the utility to the consumer of such a 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, final rules for new or amended energy conservation standards promulgated after July 1, 2010, are 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 and standards for refrigerators, refrigerator-freezers, and freezers address standby mode and off mode energy use, as do the amended standards adopted in this direct final rule. 
Finally, EISA 2007 amended EPCA, in 
relevant part, to grant DOE authority to issue a final rule (i.e., a ‘‘direct final 
rule’’) establishing an energy conservation standard upon 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) or 42 U.S.C. 6313(a)(6)(B), as applicable. 
The direct final rule must be 
published simultaneously with a NOPR that proposes an energy or water conservation standard that is identical to the standard established in 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)) While DOE typically provides a comment period of 60 days on proposed standards, for a NOPR accompanying a direct final rule, DOE provides a comment period of the same length as the comment period on the direct final rule—i.e., 110 days. 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. 6313(a)(6)(B), or any other applicable law. (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.) 
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 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 (‘‘September 2011 
Final Rule’’), DOE prescribed the current energy conservation standards for refrigerators, refrigerator-freezers, and freezers manufactured on and after September 15, 2014. 76 FR 57516. These standards are set forth in DOE’s regulations at 10 CFR 430.32(a). 
2. Current Test Procedure 
On December 23, 2019, DOE 
published a test procedure NOPR 
(‘‘December 2019 TP NOPR’’) proposing to amend residential refrigerator, refrigerator-freezer, and freezer test procedure. 84 FR 70842. 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 the NOPR are based on the annual energy use (‘‘AEU’’) metrics as measured according to appendices A and B. History of Standards Rulemaking for Consumer Refrigerators, Refrigerator- 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

www.regulations.gov/document/EERE-2017-BT- STD-0003-0103. rule published on September 15, 2011. 
76 FR 57516. 
4. The Joint Agreement 
On September 25, 2023, DOE received 
a joint statement (i.e., the Joint 
Agreement) recommending standards 
for refrigerators, refrigerator-freezers, and freezers that was submitted by groups representing manufacturers, energy and environmental advocates, consumer groups, and a utility.
19In 
addition to the recommended standards for refrigerators, refrigerator-freezers, and freezers, the Joint Agreement also included separate recommendations for several other covered products.
20And, 
while acknowledging that DOE may implement these recommendations in separate rulemakings, the Joint Agreement also stated that the recommendations were recommended as a complete package and each recommendation is contingent upon the other parts being implemented. DOE understands this to mean that the Joint Agreement is contingent upon DOE initiating rulemaking processes to adopt all of the recommended standards in the agreement. That is distinguished from an agreement where issuance of an amended energy conservation standard for a covered product is contingent on issuance of amended energy conservation standards for the other covered products. If the Joint Agreement were so construed, it would conflict with the anti-backsliding provision in 42 U.S.C. 6295(o)(1), because it would imply the possibility that, if DOE were unable to issue an amended standard for a certain product, it would have to withdraw a previously issued standard for one of the other products. The anti- backsliding provision, however, prevents DOE from withdrawing or amending an energy conservation standard to be less stringent. As a result, DOE will be proceeding with individual rulemakings that will evaluate each of the recommended standards separately under the applicable statutory criteria. The 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 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, on February 27, 2023, DOE published a NOPR and announced a public webinar (‘‘February 2023 NOPR’’) seeking comment on its proposed amended standard to inform its decision consistent with its obligations under EPCA and the Administrative Procedure Act (‘‘APA’’). 88 FR 12452. DOE held a public webinar on April 11, 2023, to discuss and receive comments on the NOPR and NOPR TSD. The NOPR TSD is available at: www.regulations.gov/document/ 
EERE-2017-BT-STD-0003-0045. 
Although DOE is adopting the Joint 
Agreement as a direct final rule and no longer proceeding with its own rulemaking, DOE did consider relevant comments, data, and information obtained during that rulemaking process 
in determining whether the recommended standards from the Joint Agreement are in accordance with 42 
U.S.C. 6295(o). Any discussion of comments, data, or information in this direct final rule that were obtained during DOE’s own prior rulemaking will include a parenthetical reference that provides the location of the item in the public record.
22 
III. General Discussion 
DOE is issuing this direct final rule 
after determining that the recommended standards submitted in the Joint Agreement meet the requirements in 42 U.S.C. 6295(p)(4). More specifically, DOE has determined that the recommended standards were submitted by interested persons that are fairly representative of relevant points of view and the recommended standards satisfy the criteria in 42 U.S.C. 6295(o). 
A. Scope of Coverage 
This direct final rule covers those 
consumer products that meet the 
definition of ‘‘refrigerator, refrigerator- freezer, and freezer’’ as codified at 10 CFR 430.2. 
When evaluating and establishing 
energy conservation standards, DOE divides covered products into product classes by the type of energy used, or by capacity, or based upon performance- related features that justify a higher or lower standard. (42 U.S.C. 6295(q)) In making a determination whether a performance-related feature justifies a

23DOE also presents a sensitivity analysis that 
considers impacts for products shipped in a 9-year 
period. 
24The FFC metric is discussed in DOE’s 
statement of policy and notice of policy amendment. 76 FR 51282 (Aug. 18, 2011), as amended at 77 FR 49701 (Aug. 17, 2012). different standard, DOE must consider 
such factors as the utility of the feature to the consumer and other factors DOE determines are appropriate. Id. 
The Joint Agreement proposed special 
door and multi-door energy allowances for product classes if manufacturers offer models with those features. Energy allowances applied to energy use equations correspond to performance- related features that would then justify new product classes for those configurations with special door and multi-door designs. The proposed approach also embeds within the energy use equations the difference between classes that are otherwise identical except for presence of an icemaker, using a logical variable I (equal to 1 for a product with an icemaker and equal to 0 for a product without an icemaker) multiplied by the constant icemaker energy use adder. 
The structure simplification and 
amendments in the Joint Agreement are consistent with those proposed by DOE in the February 2023 NOPR. Based on the comments received in response to the February 2023 NOPR and DOE’s evaluation of the Joint Agreement, the direct final rule adopts these changes. See section IV.A.1 of this document for 
further detail and discussion regarding the product classes analyzed in this direct final rule. 
B. Fairly Representative of Relevant 
Points of View 
Under the direct final rule provision 
in EPCA, recommended energy conservation standards must be submitted 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 DOE. (42 U.S.C. 6295(p)(4)(A)) With respect to this requirement, DOE notes that the Joint Agreement included a trade association, AHAM, which represents 20 manufacturers of refrigerators, refrigerator-freezers, and freezers. The Joint Agreement also included environmental and energy-efficiency advocacy organizations, consumer advocacy organizations, and a gas and electric utility company. Additionally, DOE received a letter in support of the Joint Agreement from the States of New York, California, and Massachusetts (see comment No. 104). DOE also received a letter in support of the Joint Agreement from the gas and electric utility, SDG&E, and the electric utility, SCE (see comment No. 107). As a result, DOE has determined that the Joint Agreement was submitted by interested persons who are fairly representative of relevant points of view. 
C. Technological Feasibility 1. General 
In each energy conservation standards 
rulemaking, DOE conducts a screening 
analysis based on information gathered on all current technology options and prototype designs that could improve the efficiency of the products or equipment that are the subject of the rulemaking. As the first step in such an analysis, DOE develops a list of technology options for consideration in consultation with manufacturers, design engineers, and other interested parties. DOE then determines which of those means for improving efficiency are technologically feasible. DOE considers technologies incorporated in commercially available products or in working prototypes to be technologically feasible. Sections 6(b)(3)(i) and 7(b)(1) of appendix A to 10 CFR part 430, subpart C (‘‘Process Rule’’). 
After DOE has determined that 
particular technology options are technologically feasible, it further evaluates each technology option in light of the following additional screening criteria: (1) practicability to manufacture, install, and service; (2) adverse impacts on product utility or availability; (3) adverse impacts on health or safety and (4) unique-pathway proprietary technologies. Section 7(b)(2)–(5) of the Process Rule. Section IV.B of this document discusses the results of the screening analysis for refrigerators, refrigerator-freezers, and freezers, particularly the designs DOE considered, those it screened out, and those that are the basis for the standards considered in this rulemaking. For further details on the screening analysis for this rulemaking, see chapter 4 of the 
direct final rule TSD. 
2. Maximum Technologically Feasible 
Levels 
When DOE proposes to adopt an 
amended standard for a type or class of covered product, it must determine the maximum improvement in energy efficiency or maximum reduction in energy use that is technologically feasible for such product. (42 U.S.C. 6295(o)(2)(A)) Accordingly, in the engineering analysis, DOE determined the maximum technologically feasible (‘‘max-tech’’) improvements in energy efficiency for refrigerators, refrigerator- freezers, and freezers, using the design parameters for the most efficient products available on the market or in working prototypes. The max-tech levels that DOE determined for this rulemaking are described in section IV.C of this document and in chapter 5 of the direct final rule TSD. 
D. Energy Savings 1. Determination of Savings 
For each trial standard level (‘‘TSL’’), 
DOE projected energy savings from 
application of the TSL to refrigerators, refrigerator-freezers, and freezers purchased in the 30-year period that begins in the year of compliance with the amended standards (2027–2056 for all TSLs other than TSL 4; for TSL 4, 2029–2058 for the product classes listed in Table I.1 and 2030–2059 for the product classes listed in Table I.2).
23 
The savings are measured over the entire lifetime of products purchased in the 30-year analysis period. DOE quantified the energy savings attributable to each TSL as the difference in energy consumption between each standards case and the no- new-standards case. The no-new- standards case represents a projection of energy consumption that reflects how the market for a product would likely evolve in the absence of amended energy conservation standards. 
DOE used its national impact analysis 
(‘‘NIA’’) spreadsheet models to estimate national energy savings (‘‘NES’’) from potential amended standards for refrigerators, refrigerator-freezers, and freezers. The NIA spreadsheet model (described in section IV.H of this document) calculates energy savings in terms of site energy, which is the energy directly consumed by products at the locations where they are used. For electricity, DOE reports national energy savings in terms of primary energy savings, which is the savings in the energy that is used to generate and transmit the site electricity. For natural gas, the primary energy savings are considered to be equal to the site energy savings. DOE also calculates NES in terms of full-fuel cycle (‘‘FFC’’) energy savings. The FFC metric includes the energy consumed in extracting, processing, and transporting primary fuels (i.e., coal, natural gas, petroleum 
fuels), and thus presents a more complete picture of the impacts of energy conservation standards.
24DOE’s 
approach is based on the calculation of an FFC multiplier for each of the energy types used by covered products or

Consideration in New or Revised Energy 
Conservation Standards and Test Procedures for Consumer Products and Commercial/Industrial Equipment, 86 FR 70892, 70901 (Dec. 13, 2021). equipment. For more information on 
FFC energy savings, see section IV.H.2 
of this document. 
2. Significance of Savings 
To adopt any new or amended 
standards for a covered product, DOE 
must determine that such action would result in significant energy savings. (42 U.S.C. 6295(o)(3)(B)) 
The significance of energy savings 
offered by a new or amended energy conservation standard cannot be determined without knowledge of the specific circumstances surrounding a given rulemaking.
25For example, some 
covered products and equipment have most of their energy consumption occur during periods of peak energy demand. The impacts of these products on the energy infrastructure can be more pronounced than products with relatively constant demand. However, residential refrigerators, freezers, and refrigerator-freezers have loads that are more consistent throughout the year. Accordingly, DOE evaluates the significance of energy savings on a case- by-case basis, taking into account the significance of cumulative FFC national energy savings, the cumulative FFC emissions reductions, and the need to confront the global climate crisis, among other factors. 
As stated, the standard levels adopted 
in this direct final rule are projected to result in national energy savings of 5.6 quads (FFC), the equivalent of the primary annual energy use of 37 million homes. Based on the amount of FFC savings, the corresponding reduction in emissions, and need to confront the global climate crisis, DOE has determined the energy savings from the standard levels adopted in this direct final rule are ‘‘significant’’ within the meaning of 42 U.S.C. 6295(o)(3)(B). 
E. Economic Justification 1. Specific Criteria 
As noted previously, EPCA provides 
seven factors to be evaluated in 
determining whether a potential energy conservation standard is economically justified. (42 U.S.C. 6295(o)(2)(B)(i)(I)– (VII)) The following sections discuss how DOE has addressed each of those seven factors in this rulemaking. 
a. Economic Impact on Manufacturers 
and Consumers 
In determining the impacts of 
potential amended standards on manufacturers, DOE conducts an MIA, 
as discussed in section IV.J of this document. DOE first uses an annual cash flow approach to determine the quantitative impacts. This step includes both a short-term assessment—based on the cost and capital requirements during the period between when a regulation is issued and when entities must comply with the regulation—and a long-term assessment over a 30-year period. The industry-wide impacts analyzed include (1) INPV, which values the industry on the basis of expected future cash flows; (2) cash flows by year; (3) changes in revenue and income; and (4) other measures of impact, as appropriate. Second, DOE analyzes and reports the impacts on different types of manufacturers, including impacts on small manufacturers. Third, DOE considers the impact of standards on domestic manufacturer employment and manufacturing capacity, as well as the potential for standards to result in plant closures and loss of capital investment. Finally, DOE takes into account cumulative impacts of various DOE regulations and other regulatory requirements on manufacturers. 
For individual consumers, measures 
of economic impact include the changes in LCC and payback period (‘‘PBP’’) associated with new or amended standards. These measures are discussed further in the following section. For consumers in the aggregate, DOE also calculates the national net present value of the consumer costs and benefits expected to result from particular standards. DOE also evaluates the impacts of potential standards on identifiable subgroups of consumers that may be affected disproportionately by a standard. 
b. Savings in Operating Costs Compared 
To Increase in Price (LCC and PBP) 
EPCA requires DOE to consider the 
savings in operating costs throughout 
the estimated average life of the covered product in the type (or class) compared to any increase in the price of, or in the initial charges for, or maintenance expenses of, the covered product that are likely to result from a standard. (42 U.S.C. 6295(o)(2)(B)(i)(II)) DOE conducts this comparison in its LCC and PBP analysis. 
The LCC is the sum of the purchase 
price of a product (including its installation) and the operating cost (including energy, maintenance, and repair expenditures) discounted over the lifetime of the product. The LCC analysis requires a variety of inputs, such as product prices, product energy consumption, energy prices, maintenance and repair costs, product lifetime, and discount rates appropriate 
for consumers. To account for uncertainty and variability in specific inputs, such as product lifetime and discount rate, DOE uses a distribution of 
values, with probabilities attached to each value. 
The PBP is the estimated amount of 
time (in years) it takes consumers to recover the increased purchase cost (including installation) of a more efficient product through lower operating costs. DOE calculates the PBP by dividing the change in purchase cost due to a more stringent standard by the change in annual operating cost for the year that standards are assumed to take effect. 
For its LCC and PBP analysis, DOE 
assumes that consumers will purchase the covered products in the first year of compliance with new or amended standards. The LCC savings for the considered efficiency levels are calculated relative to the case that reflects projected market trends in the absence of new or amended standards. DOE’s LCC and PBP analysis is discussed in further detail in section IV.F of this document. 
c. Energy Savings 
Although significant conservation of 
energy is a separate statutory 
requirement for adopting an energy conservation standard, EPCA requires DOE, in determining the economic justification of a standard, to consider the total projected energy savings that are expected to result directly from the standard. (42 U.S.C. 6295(o)(2)(B)(i)(III)) As discussed in section IV.H of this document, DOE uses the NIA spreadsheet models to project national energy savings. 
d. Lessening of Utility or Performance of 
Products 
In evaluating design options and the 
impact of potential standard levels, DOE evaluates potential standards that would not lessen the utility or performance of the considered products. (42 U.S.C. 6295(o)(2)(B)(i)(IV)) Based on data available to DOE, the standards adopted in this document would not reduce the utility or performance of the products under consideration in this rulemaking. 
e. Impact of Any Lessening of 
Competition 
EPCA directs DOE to consider the 
impact of any lessening of competition, as determined in writing by the Attorney General, that is likely to result from a standard. (42 U.S.C. 6295(o)(2)(B)(i)(V)) It also directs the Attorney General to determine the impact, if any, of any lessening of 
VerDate Sep<11>2014 19:16 Jan 16, 2024 Jkt 262001 PO 00000 Frm 00015 Fmt 4701 Sfmt 4700 E:\FR\FM\17JAR2.SGM 17JAR2lotter on DSK11XQN23PROD with RULES23040 Federal Register / Vol. 89, No. 11 / Wednesday, January 17, 2024 / Rules and Regulations 
competition likely to result from a 
standard and to transmit such determination to the Secretary within 60 days of the publication of a proposed rule, together with an analysis of the nature and extent of the impact. (42 U.S.C. 6295(o)(2)(B)(ii)) DOE will 
transmit a copy of this direct final rule to the Attorney General with a request that the Department of Justice (‘‘DOJ’’) provide its determination on this issue. DOE will consider DOJ’s comments on the rule in determining whether to withdraw the direct final rule. DOE will also publish and respond to the DOJ’s comments in the Federal Register in a separate document. 
f. Need for National Energy 
Conservation 
DOE also considers the need for 
national energy and water conservation in determining whether a new or amended standard is economically justified. (42 U.S.C. 6295(o)(2)(B)(i)(VI)) The energy savings from the adopted standards are likely to provide improvements to the security and reliability of the Nation’s energy system. Reductions in the demand for electricity also may result in reduced costs for maintaining the reliability of the Nation’s electricity system. DOE conducts a utility impact analysis to estimate how standards may affect the Nation’s needed power generation capacity, as discussed in section IV.M of this document. 
DOE maintains that environmental 
and public health benefits associated with the more efficient use of energy are important to take into account when considering the need for national energy conservation. The adopted standards are likely to result in environmental benefits in the form of reduced emissions of air pollutants and greenhouse gases (‘‘GHGs’’) associated with energy production and use. DOE conducts an emissions analysis to estimate how potential standards may affect these emissions, as discussed in section IV.K of this document; the estimated emissions impacts are reported in section V.B.6 of this document. DOE also estimates the economic value of emissions reductions resulting from the considered TSLs, as discussed in section IV.L of this document. 
g. Other Factors 
In determining whether an energy 
conservation standard is economically 
justified, DOE may consider any other factors that the Secretary deems to be relevant. (42 U.S.C. 6295(o)(2)(B)(i)(VII)) To the extent DOE identifies any 
relevant information regarding economic justification that does not fit into the other categories described previously, DOE could consider such information under ‘‘other factors.’’ 
2. Rebuttable Presumption 
As set forth in 42 U.S.C. 
6295(o)(2)(B)(iii), EPCA creates a 
rebuttable presumption that an energy conservation standard is economically justified if the additional cost to the consumer of a product that meets the standard is less than three times the value of the first year’s energy savings resulting from the standard, as calculated under the applicable DOE test procedure. DOE’s LCC and PBP analyses generate values used to calculate the effect potential amended energy conservation standards would have on the payback period for consumers. These analyses include, but are not limited to, the 3-year payback period contemplated under the rebuttable-presumption test. In addition, DOE routinely conducts an economic analysis that considers the full range of impacts to consumers, manufacturers, the Nation, and the environment, as required under 42 U.S.C. 6295(o)(2)(B)(i). The results of this analysis serve as the basis for DOE’s evaluation of the economic justification for a potential standard level (thereby supporting or rebutting the results of any preliminary determination of economic justification). The rebuttable- presumption payback calculation is discussed in section IV.F of this document. 
IV. Methodology and Discussion of 
Related Comments 
This section addresses the analyses 
DOE has performed for this rulemaking with regard to refrigerators, refrigerator- freezers, and freezers. Separate subsections address each component of DOE’s analyses, including relevant comments DOE received during its separate rulemaking to amend the energy conservation standards for refrigerators, refrigerator-freezers, and freezers prior to receiving the Joint Agreement. 
DOE used several analytical tools to 
estimate the impact of the standards considered in this document. The first tool is a spreadsheet that calculates the LCC savings and PBP of potential amended or new energy conservation standards. The national impacts analysis uses a second spreadsheet set that provides shipments projections and calculates national energy savings and net present value of total consumer costs and savings expected to result from potential energy conservation standards. DOE uses the third spreadsheet tool, the Government Regulatory Impact Model (‘‘GRIM’’), to assess manufacturer impacts of potential standards. These three spreadsheet tools are available on the DOE website for this rulemaking: www.regulations.gov/ 
docket/EERE-2017-BT-STD-0003. Additionally, DOE used output from the latest version of the Energy Information Administration’s (‘‘EIA’s’’) Annual Energy Outlook (‘‘AEO’’) for the emissions and utility impact analyses. 
A. Market and Technology Assessment 
DOE develops information in the 
market and technology assessment that 
provides an overall picture of the market for the products concerned, including the purpose of the products, the industry structure, manufacturers, market characteristics, and technologies used in the products. This activity includes both quantitative and qualitative assessments, based primarily on publicly available information. The subjects addressed in the market and technology assessment for this rulemaking include (1) a determination of the scope of the rulemaking and product classes, (2) manufacturers and industry structure, (3) existing efficiency programs, (4) shipments information, (5) market and industry trends, and (6) technologies or design options that could improve the energy efficiency of refrigerators, refrigerator- freezers, and freezers. The key findings of DOE’s market assessment are summarized in the following sections. See chapter 3 of the direct final rule 
TSD for further discussion of the market and technology assessment. 
1. Product Classes 
The Joint Agreement specifies 32 
product classes for refrigerators, 
refrigerator-freezers, and freezers. (Joint Agreement, No. 103 at p. 15–16) In particular, the Joint Agreement recommends a consolidated product class representation which incorporates icemaker energy adders and door allowances into the energy use equations for product classes in which they are applicable. In addition, the Join Agreement proposes a new product class—upright built-in freezers with automatic defrost and through-the-door ice service (‘‘9A–BI’’). (Id.) In this direct final rule, DOE is adopting the product classes from the Joint Agreement, as listed in Table IV.1.

26EPCA specifies that DOE may not prescribe an 
amended or new standard if the Secretary finds 
(and publishes such finding) that 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 at the time of the Secretary’s finding.

DOE further notes that product classes 
established through EPCA’s direct final 
rule authority are not subject to the criteria specified at 42 U.S.C. 6295(q)(1) for establishing product classes. Nevertheless, in accordance with 42 U.S.C. 6295(o)(4)—which is applicable to direct final rules—DOE has concluded that the standards adopted in this direct final rule will not result in the unavailability in any covered product type (or class) of performance characteristics, features, sizes, 
capacities, and volumes that are substantially the same as those generally available in the United States currently.
26DOE’s findings in this 
regard are discussed in detail in section V.B.4 of this document. a. Product Classes With Automatic 
Icemakers 
The Joint Agreement includes a 
proposed simplification of maximum allowable energy and would express the maximum allowable energy use for both icemaking and non-icemaking classes in the same equation, thus consolidating the presentation of classes and their energy conservation standards. The energy use equations will, for those classes that may or may not have an icemaker, include a term equal to the icemaking energy use adder multiplied by a factor that is defined to equal 1 for products with icemakers and to equal zero for products without icemakers. This approach does not combine classes that are the same other than the presence of an icemaker, but does simplify the list of classes and representation of their maximum allowable energy use, providing for each set of classes with and without ice makers a single equation for maximum energy use. (88 FR 12452) 
DOE is adopting the Joint Agreement 
proposal to express the maximum allowable energy use for any set of classes differing only in whether the class includes an icemaker or not within 
a single equation. The single equation does this by including the icemaker energy use adder multiplied by logical variable I that is set equal to 1 for a product with an icemaker present and 0 for a product without an icemaker. 
b. Special Door and Multi-Door Designs 
The Joint Agreement made 
recommendations to establish new 
product classes for models that 
implement special and multi-door designs. The standards for these product classes include energy allowances (i.e., specific increases in maximum allowable energy use) corresponding to the specific performance-related features (i.e., door-in-door designs, 
transparent doors, and multi-door designs). The allowances include a 2- percent energy use allowance for each externally opening door in excess of the typical minimum for the class, a 6- percent total energy use allowance for a product with a door-in-door feature implemented in one or more of its doors, and a 10-percent total energy use allowance for a product with a transparent door or doors.

27CERA is an updated version of the 
Environmental Protection Agency’s Refrigerator 
Analysis (‘‘ERA’’) program. Earlier versions have been used in previous refrigerator, refrigerator- freezer, and freezer energy conservation standards rulemaking. CERA allows for the simulation of thermal load on refrigerators, refrigerator-freezers, and freezers based of the inputs given for various parameters including cabinet design, compartment dimensions, door design, operating temperatures, controls, anti-sweat heat, and more. More information regarding the software is found in the direct final rule TSD. In this direct final rule, DOE is 
implementing the recommended special 
door and multi-door energy allowances. DOE’s direct rulemaking authority under 42 U.S.C. 6295(p)(4) is constrained only by the requirements of 42 U.S.C. 6295(o), which does not include the product class requirements in 42 U.S.C. 6295(q). DOE is relying on the product classes provided in the Joint Agreement for consideration in this rule, but DOE notes that special doors (i.e., transparent doors and door-in-door 
features) and multi-door setups constitute performance-related features that provide consumer utility when implemented. Transparent doors allow for partial view into the interior of fresh food compartments without the need for 
a door opening. Door-in-door features generally allow for access to a partially separated fresh food compartment without the need to fully expose the main interior fresh food compartment. Multi-door setups provide at least one additional externally opening door accessing either an existing compartment or a separate compartment, thus providing additional options for storage and access to food for the consumer. 
Furthermore, DOE’s analysis of these 
features suggests that special door and multi-door designs impact energy usage with some combinations accounting for additional energy consumption of up to 25 percent (based on CERA simulations).
27DOE notes that the 
additional energy usage results from additional thermal load associated with additional gasket length necessary for multi-door and door-in-door features, and associated with the higher thermal conductivity of transparent doors compared to solid doors of the same size. DOE also proposed similar special door and multi-door energy allowances in the February 2023 NOPR and finds that the recommended allowances in the Joint Agreement are justifiable on a similar basis in light of the analysis DOE performed to develop the allowances proposed in the NOPR. See chapter 5 of 
the direct final rule TSD for more information on DOE’s analysis of special door and multi-door features. For the reasons previously discussed, 
DOE is adopting the Joint Agreement 
recommendations to establish new product classes for models that implement special and multi-door designs. 
Energy Use Allowance—Application 
AHAM, Sub Zero Group, Inc. (‘‘Sub 
Zero’’), and Samsung also recommended 
that DOE apply the door coefficient to PC 4, PC 4–BI, PC 9, and PC 9–BI, as these classes have products offering multi-door setups or special doors that provide similar customer utility. (AHAM, No. 69 at p. 8; Sub Zero, No. 77 at p. 4; Samsung, No. 78 at p. 3) True Manufacturing (‘‘TRUE’’) similarly stated that PC 4I and PC 4, and any other product classes with transparent doors, should have the same transparent door allowance as PC 5A and PC 5. (TRUE, No. 57 at pp. 1–2) 
DOE’s assessment regarding the 
energy impact of designs featuring multi-door and special door setups warranted the proposal of energy allowances for classes where such features are offered. DOE reviewed the market and requested input from commenters related to existing models on the market in an effort to assess the prevalence of multi-door designs or special doors in products on the market today and concluded that there likely exist such models in PC 4I, PC 4I–BI, PC 9, and PC 9–BI that implement multi- 
door setups, special doors, or both. Therefore, DOE is adopting the multi- door and transparent door energy allowances for PC 4, PC 4I, PC 4–BI, PC 4I–BI, PC 9, and PC 9–BI consistent with feature availability. PC 4, PC 4I, PC 4– BI, and PC 4I–BI will be eligible for transparent door and multi-door allowances, while PC 9, and PC 9–BI will be eligible for the multi-door allowance. The magnitude and application of the allowances adopted for the aforementioned product classes are consistent with those recommended in the Joint Agreement. DOE notes that PC 4 and PC 4–BI will be eligible for a 2 percent allowance for each additional door for products without a transparent door or door-in-door with added external doors, a 6 percent allowance for products without a transparent door with a door-in-door, or a 10 percent transparent door allowance for the use of a qualifying transparent door. PC 9 and PC 9–BI will be eligible for a 2 percent allowance for each additional door up to two additional doors. 
Energy Use Allowance—Definitions 
The Joint Agreement includes the 
following recommended definition for a 
transparent door: •Transparent door means a door for 
which 40 percent or more of the surface 
area—as determined based on the area of the transparent portion of the door divided by the product of the maximum width and height dimension of the door—is transparent to allow viewing into the refrigerated compartment. 
•Conceptually, the parties 
recommend that DOE clarify that products with only very small door or drawers that are transparent should not be included in this definition—i.e., the 
door must be large enough to justify the allowance. 
Upon further consideration of the 
February 2023 NOPR proposed transparent door definition, the feedback received from stakeholders, and the Joint Agreement submitted by interested parties, including AHAM, DOE conducted further market research into available models with transparent panels, generating a list of models from various manufacturers and product classes representative of the units currently on the market that implement transparent doors. From this list, DOE determined transparent panel and door area based on product literature, in- person measurements, or use of scaled photographs. DOE then determined the percentage of the door covered by the transparent area for each model considered. DOE found that the 
transparent door on a French door configuration typically had roughly 40 percent or more of the total outer door area transparent, consistent with the percentage recommended in the Joint Agreement. Other configurations, such as two door bottom-mount refrigerator- freezers and compact refrigerators had 54 percent or more of their outer door area transparent. Based on this assessment and consideration of the Joint Agreement recommendations, DOE is adopting a modified definition from the February 2023 NOPR for transparent doors to better align with the products on the market, as follows: 
Transparent door means an external 
fresh food compartment door which meets the following criteria: 
•The area of the transparent portion 
of the door is at least 40 percent of the area of the door. 
•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.

DOE notes that this amended 
transparent door definition not only 
aligns with the typical implementation on the market, as previously described, but also is a more straightforward approach compared to those recommended and referenced by commenters. Specifically, DOE expects that the suggested approach based on the internal cabinet dimensions has some potential for questions about interpretation, given the fact that the interior dimensions could vary from the front of the cabinet to the rear. This could lead to varying internal cabinet area determinations. Therefore, in order to eliminate this potential variation, DOE is adopting the above definition and approach that simplifies the determination of the transparent door area by measuring and determining the area of the transparent portion divided by the product of the maximum height and width dimensions of the door. 
Energy Use Allowance—Summary 
In summary, in this direct final rule 
DOE is adopting the multi-door and 
special door energy use allowances as proposed in the Joint Agreement, with the specified amendments as previously discussed. 
c. Addition of Product Class 9A–BI 
The Joint Agreement recommends the 
addition of a new product class 9A–BI 
(i.e., built-in upright freezers with 
automatic defrost and with through-the- door ice service) and specific energy efficiency standards for the new product class. The current energy conservation standards for freezers do not include a separate product class for products of this configuration, and DOE has not previously considered establishing a separate product class for them because it has not been aware of the existence of 
such products on the market, nor has it previously been notified by any manufacturer of the potential introduction of such a product. Under the current product class structure, any such product would most appropriately fit into current class 9I–BI (i.e., built-in 
upright freezers with automatic defrost with an automatic icemaker), since there is no class that fits this description and also has through-the-door ice service. Hence, in the absence of a product class for this configuration, such products would be subject to the current PC 9I– BI standards, which would, under the approach for designating classes and standards provided in this direct final rule, correspond to class grouping 9–BI with the icemaker variable I in the standards equation equal to 1, indicating addition of the 28 kWh/year icemaker energy use. 
Considering that the recommendation 
carries support from a broad cross- section of interests, including trade 
associations representing these manufacturers, environmental and energy-efficiency advocacy organizations, consumer advocates, and electric utility providers as well as the support of several States, DOE believes it appropriate to adopt this new product class, 9A–BI. DOE notes that the addition of a PC 9A–BI, as suggested by the Joint Agreement, is warranted as the application of a through-the-door icemaker constitutes a performance related feature with consumer utility and is likely to be introduced on the market in the near future. 
DOE notes the standard as 
recommended by the Joint Agreement for PC 9A–BI is 5 percent higher than that of PC 9I–BI (built-in upright freezers with automatic defrost with an automatic icemaker). When considering class 9A–BI and 9I–BI, the key difference is the addition of through- the-door ice service, and the potential additional thermal load associated with its addition. Therefore, the 5 percent adjustment between 9I–BI and 9A–BI can be attributed mainly to the addition of through-the-door ice service. When comparing recommended standards to other product classes in which the key difference is the addition of through- the-door ice (i.e., 5I vs. 5A and 4I vs. 7), 
the 5 percent adjustment remains consistent with DOE’s adopted standards. As a result of this consistency, DOE believes the recommended standard is appropriate in its application. 
Given the indication from the 
aforementioned stakeholders that such a product class standard would be beneficial in its implementation, the classification of through-the-door ice as a performance related feature, and the recommendation’s consistency with the other adopted standards, DOE is adopting a PC 9A–BI standard in this direct final rule. 
See section V of this document for 
more information regarding the TSL configuration and discussion of the adopted level for this product class. See chapter 5 of the direct final rule TSD for more discussion regarding the addition of this product class.

B. Screening Analysis 
DOE uses the following four screening 
criteria to determine which technology 
options are suitable for further consideration in an energy conservation standards rulemaking: 
(1) Technological feasibility. Technologies 
that are not incorporated in commercial 
products or in commercially viable, existing prototypes will not be considered further. 
(2) Practicability to manufacture, install, 
and service. If it is determined that mass production of a technology in commercial products and reliable installation and servicing of the technology could not be achieved on the scale necessary to serve the relevant market at the time of the projected compliance date of the standard, then that technology will not be considered further. 
(3) Impacts on product utility. If a 
technology is determined to have a significant adverse impact on the utility of the product to subgroups of consumers, or result in the unavailability of any covered product type with performance characteristics (including reliability), features, sizes, capacities, and volumes that 
are substantially the same as products generally available in the United States at the time, it will not be considered further. 
(4) Safety of technologies. If it is 
determined that a technology would have significant adverse impacts on health or safety, it will not be considered further. 
(5) Unique-pathway proprietary 
technologies. If a technology has proprietary 
protection and represents a unique pathway to achieving a given efficiency level, it will not be considered further, due to the potential for monopolistic concerns. 
10 CFR part 430, subpart C, appendix 
A, sections 6(b)(3) and 7(b). 
In summary, if DOE determines that a 
technology, or a combination of technologies, fails to meet one or more of the listed five criteria, it will be excluded from further consideration in the engineering analysis. The reasons for eliminating any technology are 
discussed in the following sections. 
The subsequent sections include 
comments from interested parties pertinent to the screening criteria, 
DOE’s evaluation of each technology option against the screening analysis criteria, and whether DOE determined that a technology option should be excluded (‘‘screened out’’) based on the screening criteria. 
1. Screened-Out Technologies 
In conducting the screening analysis 
for this direct final rule, DOE 
considered comments it had received in response to the screening analysis conducted for the February 2023 NOPR. 
In the February 2023 NOPR, DOE 
screened out the technologies presented in Table II.2 on the basis of technological feasibility, practicability to manufacture, install, and service, adverse impacts on utility or availability, adverse impacts on health and safety, and/or unique-pathway proprietary technologies.

Inert Blowing Fluid CO 2. 
GEA recommended that DOE screen 
out ‘‘improved resistivity of foam,’’ 
which is primarily hydrofluoro-olefin (‘‘HFO’’) foams, as a technology option. GEA stated that HFO foams represent a unique and proprietary technology pathway and that the two listed by DOE in the February 2023 NOPR TSD— Solstice LBA and Ecomate—should be excluded through the technology screening analysis. GEA stated that Solstice LBA, an HFO foam blowing agent is only produced by a single manufacturer, Honeywell, and should therefore be screened out from consideration in DOE’s technology assessment in this rulemaking. GEA noted that Ecomate has no proven commercialization in modern consumer 
refrigerators or freezers. (GEA, No. 75 at pp. 4–5) 
As discussed in the February 2023 
NOPR, HFO foams are retained as a design option and passed the screening analysis because the technology option meets the five criteria previously mentioned. While GEA notes Ecomate has no proven commercialization in modern consumer refrigerators or freezer, as discussed in more detail in section 3.4.2.1 of the February 2023 NOPR TSD, improved resistivity foams such as Solstice have been implemented in refrigerator-freezer models in the United States, as of at least 2014
28and 
DOE has not received information regarding negative impacts to product utility or impracticability to manufacture or service products using improved resistivity foam. Some of the 
improved blowing agents reviewed by DOE (e.g., CO
2) have been found to be 
non-flammable and lower in GWP than traditional insulation. DOE acknowledges that Solstice LBA is patented by Honeywell but included other potential technologies such as added carbon black and CO
2blowing 
agents in its assessment. Therefore, as a technology option, DOE maintains that HFO foams meet the prerequisites to be included past the screening analysis. However, because DOE could not determine the type of foam used in the directly analyzed models from teardowns or based on the feedback from manufacturers, DOE found that there was an insufficient basis to implement this design option as a means to increase energy efficiency in either the February 2023 NOPR or this direct final rule analysis. 
An individual commented that 
microchannel condensers should not be retained as a design option, citing issues with implementation in the HVAC industry. The individual also stated that increased insulation thickness should not be retained as a design option, citing lessening of consumer utility. (Individual Commenter, No. 59 at p. 1) 
DOE has observed implementation of 
microchannel heat exchangers in PC 5I, PC 5A, and several built-in product classes. DOE has also received no information regarding negative impacts 
in consumer utility or safety, and therefore, DOE retained microchannel condensers as a design option in this analysis As with the HFO foam design option, while microchannel condensers passed the screening analysis, this design option was not included as a design pathway to achieve higher efficiency levels in the direct final rule analysis due to potential system operation drawbacks including irregular refrigerant distribution, greater refrigerant-side pressure drop, and greater air-side pressure drop.
29 
DOE expects that increased insulation 
thickness would impact either the interior or exterior dimensions of a refrigerator, refrigerator-freezer, or freezer, and as a result did not consider increased insulation thickness as a design option to achieve the higher efficiency levels for standard-size refrigerator-freezers. However, DOE expects that there is potential to increase insulation thickness for some types of freezers and compact refrigerators, given their typical use in in spaces that allow increased exterior dimensions, and therefore continues to consider increased thickness as a design option to achieve higher efficiency levels for PC 10, PC 11A, and PC 18. 
2. Remaining Technologies
Through a review of each technology,
DOE concludes that all of the other 
identified technologies listed in section IV.B.1 met all five screening criteria tobe examined further as design optionsin DOE’s direct final rule analysis. Insummary, DOE did not screen out thefollowing technology options:

DOE determined that these 
technology options are technologically 
feasible because they are being used or have previously been used in commercially available products or working prototypes. DOE also finds that all of the remaining technology options meet the other screening criteria (i.e., practicable to manufacture, install, and service and do not result in adverse impacts on consumer utility, product availability, health, or safety). For additional details, see chapter 4 of the 
direct final rule TSD. 
C. Engineering Analysis 
The purpose of the engineering 
analysis is to establish the relationship 
between the efficiency and cost of refrigerators, refrigerator-freezers, and freezers. There are two elements to consider in the engineering analysis: the selection of efficiency levels to analyze (i.e., the ‘‘efficiency analysis’’) and the 
determination of product cost at each 
efficiency level (i.e., the ‘‘cost 
analysis’’). In determining the performance of higher-efficiency products, DOE considers technologies and design option combinations not eliminated by the screening analysis. For each product class, DOE estimates the baseline cost, as well as the incremental cost for the product/ equipment at efficiency levels above baseline. The output of the engineering analysis is a set of cost-efficiency ‘‘curves’’ that are used in downstream analyses (i.e., the LCC and PBP analyses 
and the NIA). 
1. Efficiency Analysis 
DOE typically uses one of two 
approaches to develop energy efficiency 
levels for the engineering analysis: (1) relying on observed efficiency levels in the market (i.e., the efficiency-level 
approach), or (2) determining the incremental efficiency improvements associated with incorporating specific design options to a baseline model (i.e., the design option approach). Using the efficiency-level approach, the efficiency levels established for the analysis are 
determined based on the market distribution of existing products (in other words, based on the range of efficiencies and efficiency level ‘‘clusters’’ that already exist on the market). Using the design option approach, the efficiency levels established for the analysis are determined through detailed engineering calculations and/or computer simulations of the efficiency improvements from implementing specific design options that have been identified in the technology assessment. DOE may also rely on a combination of these two approaches. For example, the efficiency-level approach (based on actual products on the market) may be extended using the design option approach either to establish ‘‘gap fill’’ levels (to bridge large gaps between other identified efficiency levels) and/or to extrapolate to the ‘‘max-tech’’ level (particularly in cases where the ‘‘max- tech’’ level exceeds the maximum efficiency level currently available on the market). 
In defining the efficiency levels for 
this direct final rule, DOE considered comments it had received in response to the efficiency levels proposed in the February 2023 NOPR. 
For its analysis in this rulemaking, 
DOE used a combined efficiency level and design option approach. First, an efficiency-level approach was used to establish an analysis tied to existing products on the market. A design option approach was used to extend the analysis through ‘‘built-down’’ efficiency levels and ‘‘built-up’’ efficiency levels where there were gaps in the range of efficiencies of products that were reverse engineered. Products from PC 3, PC 5, PC 5A, PC 5-BI, PC 7, PC 9, PC 10, PC 11A, and PC 18 were 
tested and torn down to provide information to lay the groundwork for the analysis. Other product classes such as 9-BI (and the new PC 9A-BI recommended by the Joint Agreement) were not directly analyzed as a part of DOE’s analysis, as they were not deemed sufficiently representative of the market. A number of other product classes were indirectly analyzed, based on relevant directly analyzed product classes. DOE’s analysis for PC-9BI, for example, is based on the directly analyzed PC 9. 
DOE used design option analysis 
techniques to extend the analysis to higher efficiency levels and to fill any efficiency level gaps. DOE generally focuses its analysis on product classes with higher market share as their energy impact and associated energy savings are the most significant. Therefore, for this direct final rule analysis DOE chose to test and teardown units from the product classes listed above that represent a significant market share, and extrapolated the analysis to all other product classes that were not directly analyzed, as appropriate. 
a. Built-In Products 
For the analysis supporting this direct 
final rule, DOE used an assessment of 
PC 5-BI (built-in refrigerator-freezer with bottom-mounted freezer) to address built-in products. DOE conducted analysis for a representative 5-BI product and compared it to analysis conducted for freestanding models of class 5. DOE concluded that a built-in model that is comparable to a freestanding model except the built-in configuration would have 5 percent higher energy use. Therefore, for example, the potential reduction in energy use for built-in PC 5 units would be 5 percent lower than their freestanding counterparts, based on the implementation of the same design options to satisfy a higher efficiency level. DOE has applied this 5-percent differential in selecting standard levels for other built-in classes for which DOE did not conduct direct analysis (e.g., PC 
3A, PC 7, and PC 9). More information on the analysis of built-in product classes is available in the direct final rule TSD.

Product Criteria,’’ www.energystar.gov/products/ 
appliances/refrigerators/key_ product_ criteria 
(accessed July 14, 2023). b. Baseline Efficiency/Energy Use 
For each product/equipment class, 
DOE generally selects a baseline model 
as a reference point for each class, and measures changes resulting from potential energy conservation standards against the baseline. The baseline model in each product/equipment class represents the characteristics of a product/equipment typical of that class (e.g., capacity, physical size). Generally, 
a baseline model is one that just meets current energy conservation standards, or, if no standards are in place, the baseline is typically the most common or least efficient unit on the market. When selecting units for the analysis DOE selects units at baseline from various manufacturers for each directly analyzed product class. 
In determining the baseline efficiency 
level for this direct final rule analysis, DOE maintained the same approach as the February 2023 NOPR, and considered the current Federal energy conservation standards as the baseline level, expressed as maximum annual energy consumption as a function of the product’s adjusted volume, adjusting for the change in the automatic icemaker energy contribution for product classes that include this feature. The current standards incorporate an allowance of a constant 84 kWh/yr icemaker adder for product classes with automatic icemakers, consistent with the current test procedure, which requires adding this amount of annual energy use to the product’s tested performance if the product has an automatic icemaker. DOE adjusted the baseline energy usage levels for each class to account for the planned revision in the test procedure to reduce the icemaker energy use adder to 28 kWh/yr.
30 
DOE directly analyzed a sample of 
market representative models from within nine product classes from multiple manufactures. For most product classes a single representative adjusted volume was analyzed, though 
for PC 3, PC 5, and PC 11, DOE directly analyzed two representative adjusted volumes within the product class. DOE tested and tore down 13 baseline units to provide a basis for development of the cost-efficiency curves. DOE’s analysis assumed that all baseline models implement R-600a refrigerant, based on feedback during manufacturer interviews suggesting the industry has or is in the process of shifting to low- GWP refrigerants, in particular away from R-134a, in accordance with regulatory efforts to phasedown of hydrofluorocarbons.
31Further 
information on the design characteristics of specific analyzed baseline models is summarized in the direct final rule TSD. 
BSH disagreed with DOE’s use of HFO 
foam as representative of a baseline refrigerator, refrigerator-freezer, and/or freezer’s insulation in the February 2023 NOPR, citing high environmental impact of the insulation, and encouraged DOE to remove HFO foam from baseline analysis. (BSH, No. 64 at pp. 1-2) AHAM also suggested that considering HFO foam at baseline efficiency levels is inappropriate and result in an artificially high baseline efficiency, excessively stringent standards for high-volume product classes, and negative environmental impacts. (AHAM, No. 69 at pp. 4-5) 
DOE was unable to determine the type 
of insulation used in teardown models and subsequently considered PU insulation at the baseline level for all product classes in the February 2023 NOPR and in this direct final rule. Furthermore, as described in section IV.B.2 of this document, DOE retained 
the improved insulation resistivity design option (i.e., HFOs) through the 
screening analysis, though DOE did not utilize it as a design to achieve higher efficiency levels in the engineering analysis. DOE further notes, that BSH and AHAM are parties to the Joint Agreement and are supportive of the recommended standard adopted in this direct final rule. 
c. Higher Efficiency Levels 
For this direct final rule, DOE 
maintained the same approach as the 
February 2023 NOPR, and analyzed up to five incremental efficiency levels beyond the baseline for each of the analyzed product classes. For PC 3 and PC 7, DOE considered an efficiency level at roughly 5 percent more efficient than the current energy conservation standard. For all product classes, DOE considered a level near 10 percent more efficient than the current energy conservation standard, equivalent to the current ENERGY STAR
®level for 
refrigerators, refrigerator-freezers, and freezers.
32DOE then extended the 
efficiency levels (‘‘ELs’’) in steps of close to 5 percent of the current energy conservation standard up to EL 4, using applicable technologies as discussed in sections IV.A.2 and IV.B of this document. Finally, for all product classes, EL 5 represents ‘‘max-tech,’’ using design option analysis to extend the analysis beyond EL 4 using all applicable design options, including the most efficient variable-speed 
compressors available on the market, and considerable use of vacuum- insulated panels (‘‘VIPs’’) in key areas of the cabinet walls and doors. The efficiency levels analyzed beyond the baseline are shown in Table IV.4.

33DOE notes the recommended TSL for this 
direct final rule is TSL 4, discussed further in 
section V.A of this document. 34‘‘Development of Nanoporous Materials for the 
Production of Vacuum-Insulated Panels (VIPs),’’ European Commission, January 2017. Available at cordis.europa.eu/article/id/190833-insulation- nanomaterials-for-energyefficient-refrigerators (last 
accessed October 15, 2020). d. VIP Analysis and Max-Tech Levels 
As discussed in the previous section, 
DOE’s NOPR analysis considered the 
use of VIPs placed throughout the side walls and doors at max-tech levels for many product classes. 
AHAM disagreed with the extent of 
VIP use at higher efficiency levels in the engineering analysis, asserting that DOE overestimates the use and impact of VIPs in its analysis, despite acknowledging the technology’s limitations. AHAM cited panel cost, in the form of labor and production costs, which are significant due to complex installation requirements, processing controls, and quality checks. AHAM also cited lower effectiveness in smaller units due to ‘‘edge effects’’ (i.e., heat 
around the edges caused by the membrane film that forms the walls of the VIP). AHAM suggested that DOE not overestimate the impact of VIPs in its analysis, considering that VIPs are not used in a majority of products and manufacturers have reported varied levels of success using the technology. (AHAM, No. 69 at pp. 5–6) 
DOE’s implementation of VIPs in the 
analyses at each stage of this rulemaking is based on a combination of the best information gathered from multiple sources related to cost, use, and energy efficiency impacts. DOE did not specifically account for edge effect impacts on thermal load for compact refrigerator, refrigerator-freezer, or freezer models in its analysis. Regarding VIP pricing, DOE estimated VIP panel, installation, processing, and quality check costs based on a number of discussions with refrigerator manufacturers, VIP producers, and market research. DOE conducted additional interviews and research in support of this direct final rule, which further supported and solidified the VIP cost estimates. 
In manufacturer interviews, DOE also 
gathered information regarding the implementation of VIPs (e.g., locations, 
number of panels, panel area), and based on that information, DOE performed simulations to estimate the energy impacts using CERA. CERA allowed DOE to analyze the thermal load impact on a fresh food and/or freezer cabinet due to different placements of VIP paneling throughout a cabinet (e.g., side panels, doors, or 
both). DOE then compared the results from these simulations to existing research into load reductions (which estimates energy savings at around 30 percent)
34and based on both sources, 
estimated that the full implementation of VIPs in existing cabinets can reduce heat load by up to 23 percent. DOE did not specifically account for edge effect impacts on thermal load for compact refrigerator, refrigerator-freezer, or freezer models in its analysis. However, DOE notes that the engineering analysis halves the thermal load impact as observed in simulations in order to be conservative with energy savings and to account for factors that are not captured in testing and/or simulation (e.g., differences in VIP core material, VIP installation method and location). DOE also notes VIPs are not implemented in most classes until efficiency levels above that proposed in the February 2023 NOPR and adopted in this direct final rule. 
Sub Zero commented that as a small, 
low-volume manufacturer of niche built-in style refrigeration products, it is concerned that the standards proposed in the February 2023 NOPR will create a significant supply chain burden for them, as components like vacuum insulation panels are supplied by a limited number of manufacturers, which will impede their ability to deliver products to their consumers in a timely manner. Sub Zero requested that DOE reduce the stringency level of adopted standards for built-in products, to reduce these concerns. (Sub Zero, No. 77 at p. 2) 
To better characterize and understand 
the VIP market, DOE conducted research and interviewed relevant VIP manufacturers to gather more data regarding the current global VIP market, and to identify any potential supply chain constraints related to the adoption of more stringent energy conservation standards. DOE estimates that the current demand for VIPs in the U.S. refrigerator market is roughly 1 to 3 million VIP panels, whereas the global supply for VIPs is estimated to exceed 10 million panels. Despite relatively low demand for VIPs in the U.S. market, there is notable VIP use in the European and Asian markets, with supply available from at least three major VIP manufacturers. Based on the information gathered, DOE expects that VIP production lines can be quickly scaled up to meet demand of future amended standards (within 1 to 2 years depending on the specific VIP design), well within 3-year lead time between publication of amended standards and 
the compliance date for those standards. 
In response to stakeholder feedback 
on the February 2023 NOPR, DOE carefully considered the use of VIPs in its analysis, generally implementing VIPs at the highest efficiency levels as one of the last design options considered. Therefore, based on the engineering analysis and its consideration of VIPs, DOE expects that to meet the adopted standards, manufacturers are likely to implement VIPs only in PC 5 (for three-door, 30 AV configuration) and PC 5A, with partial VIP usage for both classes. 
e. Variable-Speed Compressor Supply 
Chain 
Numerous commenters on the 
February 2023 NOPR suggested that supply chains for VIPs and variable- speed compressor (‘‘VSC’’) may not support the quantities of those components that may be required at the efficiency levels proposed in the NOPR. AHAM recommended that DOE conduct a review of component availability and supply chain capacity for VSCs given the general global market trends for increasingly stringent standards for cooling appliances, including both air conditioning and refrigeration. (AHAM, No. 69 at p. 5) Whirlpool further noted that the proposed standards may result in increased component costs to manufacturers due to those same supply chain constraints, especially given that VSCs would be necessary for nearly all evaluated product classes. (Whirlpool, No. 70 at p. 5) Sub Zero also expressed 
concern that the proposed standards will create a significant supply chain burden for small, low-volume manufacturer of niche market built-in style refrigeration products because VSCs are provided by a limited number of suppliers. Sub Zero commented that the proposed standards will impede the ability of these small manufacturers to deliver to their niche consumers in a timely manner. (Sub Zero, No. 77 at p. 2) 
Samsung supported DOE’s proposed 
energy conservation standards for refrigerators, refrigerator-freezers, and freezers and the use of VSC technology as a significant energy-saving option. Samsung stated that there is already significant market availability of VSCs, and a regulatory certainty and 3-year compliance period would provide ample time for manufacturers and suppliers to establish sufficient supply availability of VSCs. (Samsung, No. 78 at p. 2) 
In response to these comments, DOE 
interviewed relevant compressor manufacturers to gather information 
VerDate Sep<11>2014 19:16 Jan 16, 2024 Jkt 262001 PO 00000 Frm 00025 Fmt 4701 Sfmt 4700 E:\FR\FM\17JAR2.SGM 17JAR2lotter on DSK11XQN23PROD with RULES23050 Federal Register / Vol. 89, No. 11 / Wednesday, January 17, 2024 / Rules and Regulations 
regarding the level of VSC 
implementation that would be required at the efficiency levels in this rule, the current and predicted supply of VSCs into the U.S. market, the predicted time to ramp up production of VSCs, and pricing of VSC compressors and components. DOE notes that the VSC compressors focused on in this supply chain analysis differ from those utilized in air conditioners and other non- related cooling appliances. VSC compressors utilized in refrigerators, refrigerator-freezers, and freezers are generally different designs, are manufactured in different factories, and are generally produced by different manufacturers. Thus, based on the information provided by these manufacturers, DOE has determined that the industry is able to meet the increased demand of VSCs amid likely growing demand in the U.S. market. 
Based on manufacturer interviews, 
DOE estimates the current total global demand for refrigerator, refrigerator- freezer, and freezer compressors (all compressors, not just VSCs) is 230 million. Total compressor production capacity is much higher than demand, with global capacity for compressors estimated at over 400 million. Globally, there has been a shift towards VSC utilization in response to increasing energy efficiency regulations in the European Union (‘‘EU’’) and Japan. Estimates project upwards of a quarter of the global market and a third of the U.S. market currently utilize VSCs in refrigerators, refrigerator-freezers, and freezers. Considering the U.S. market accounts for an estimated 12 million consumer refrigeration products, a conservative estimate puts U.S. current demand for VSC compressors at roughly 4 million. 
Given DOE’s understanding of the 
compressor marketplace, the expected time to build capacity to meet the new demand is expected to be significantly shorter than the 5 and 6-year lead time between direct final rule publication and the compliance date, with estimates ranging from 8 months to 1 year. Compressor manufacturers indicated that VSC production capacity has been increasing by 7 million per year between 2018 and 2022. Additionally, high-efficiency VSC compressor designs 
are already developed and do not require additional qualification testing before production. Research and development (‘‘R&D’’) time to develop compressor designs is not required and thus would not be a factor affecting availability. 
DOE is aware that there have been 
supply constraints for VSCs recently due to issues with electronic component supply caused by the COVID–19 pandemic. Specifically, Chinese manufacturing and shipping of compressors decreased significantly during COVID-related lockdowns throughout the country between 2020 and 2022. Due to China’s outsized impact on global supply, the effects of lockdowns were felt globally. Now that lockdowns have ended, however, the affected factories are open again and in production. Compressor manufacturers also indicated that they have been modifying sourcing strategies, in many cases establishing their own electronic component assembly lines in order to protect against potential future issues that could affect supply and production of VSCs. 
In considering all of the information 
provided by relevant manufacturers of VSCs, DOE believes that significant increases in VSCs in the U.S. market aligned with the standard levels adopted in this direct final rule are well within the production capacity of the compressor industry. DOE further notes, that AHAM, Whirlpool, Sub Zero, and Samsung are parties to the Joint Agreement and are supportive of the recommended standard adopted in this direct final rule. 
f. Product Classes 11 and 12 Alignment 
The Joint Agreement recommended 
that DOE adopt a level of 10 percent 
energy savings relative to the current PC 12 standard. In light of the recommendation outlined in the Joint Agreement, and in consideration of comments received in response to the February 2023 NOPR, DOE is adopting a percentage increase in efficiency for PC 12 at 10 percent lower relative to the current standard. Additionally, as recommended in the Joint Agreement and proposed in the February 2023 NOPR, DOE is including a multi-door energy use allowance for PC 12 for products with two doors. 
2. Cost Analysis 
The cost analysis portion of the 
engineering analysis is conducted using 
one or a combination of cost approaches. The selection of cost approach depends on a suite of factors, including the availability and reliability of public information, characteristics of the regulated product, the availability and timeliness of purchasing the product on the market. The cost approaches are summarized as follows: 
•Physical teardowns: Under this 
approach, DOE physically dismantles a commercially available product, component-by-component, to develop a detailed bill of materials for the product. •Catalog teardowns: In lieu of 
physically deconstructing a product, 
DOE identifies each component using parts diagrams (available from manufacturer websites or appliance repair websites, for example) to develop the bill of materials for the product. 
•Price surveys: If neither a physical 
nor catalog teardown is feasible (for example, for tightly integrated products such as fluorescent lamps, which are infeasible to disassemble and for which parts diagrams are unavailable) or cost- prohibitive and otherwise impractical (e.g., large commercial boilers), DOE 
conducts price surveys using publicly available pricing data published on major online retailer websites and/or by soliciting prices from distributors and other commercial channels. 
In the direct final rule analysis, DOE 
conducted the analysis using a combination of physical teardowns, catalog teardowns, and price surveys. Where possible, physical teardowns were used to provide a baseline of technology options and pricing for a specific product class at a specific EL. Then with technology option information, DOE estimated the cost of various design options including 
compressors, VIPs, and insulation, by extrapolating the costs from price surveys. With specific costs for technology options, DOE was then able to ‘‘build-up’’ or ‘‘build-down’’ from the various teardown models to finish the cost-efficiency curves. DOE used this approach to calibrate the analysis to certified or measured energy use of specific available models where possible, while allowing a broader range of potential efficiency levels to be considered. 
The resulting bill of materials 
provides the basis for the manufacturer production cost (‘‘MPC’’) estimates. 
To account for manufacturers’ non- 
production costs and profit margin, DOE applies a multiplier (the manufacturer markup) to the MPC. The resulting manufacturer selling price (‘‘MSP’’) is the price at which the manufacturer distributes a unit into commerce. DOE developed an average manufacturer markup by examining the annual Securities and Exchange Commission (‘‘SEC’’) 10–K reports filed by publicly traded manufacturers primarily engaged in appliance manufacturing and whose combined product range includes refrigerators, refrigerator-freezers, and freezers. 
3. Cost-Efficiency Results

are presented as cost-efficiency data for 
each of the efficiency levels for each of the analyzed product classes that were

analyzed. DOE developed estimates of 
MPCs for each unit in the teardown sample, and also performed additional modeling based on representative teardown samples, to extend the analysis to cover the range of efficiency levels appropriate for a representative product. To estimate the MPCs 
necessary to achieve higher efficiency levels, in particular those beyond the highest-efficiency products in the test sample, DOE considered design options that were most likely to be considered and implemented by manufacturers to achieve the higher efficiency levels. Based on input from manufacturers and an understanding of the markets, DOE then estimated the costs associated with those design option to determine the MPCs at each of the analyzed efficiency levels. 
The efficiency levels and design 
option progression for the analyzed standard-size refrigerator-freezers are presented in Table IV.5. The cells in the table list the design options that DOE considered at each higher efficiency 
level as compared with the next-lower efficiency level. Similarly, the efficiency levels and design options for standard- size freezers and Compact refrigerators, refrigerator-freezers are presented in Table IV.6. The MPCs for the analyzed product classes across the considered efficiency levels are presented in Tables IV.7 and IV.8. See chapter 5 of the direct 
final rule TSD for additional detail on the engineering analysis.

4. Manufacturer Selling Price 
To account for manufacturers’ non- 
production costs and revenue 
attributable to the product, DOE applies a multiplier (the manufacturer markup) to the MPC. The resulting manufacturer selling price (‘‘MSP’’) is the price at which the manufacturer distributes a unit into commerce. DOE developed an average manufacturer markup by examining the annual Securities and Exchange Commission (‘‘SEC’’) 10–K reports
35filed by publicly traded 
manufacturers primarily engaged in appliance manufacturing and whose combined product range includes 
refrigerators, refrigerator-freezers, and freezers. See chapter 12 of the direct 
final rule TSD for additional detail on the manufacturer markup. 
D. Markups Analysis 
The markups analysis develops 
appropriate markups (e.g., retailer 
markups, wholesaler markups, 
contractor markups) in the distribution chain and sales taxes to convert the MSP estimates derived in the engineering analysis to consumer prices, which are then used in the LCC and PBP analysis. At each step in the distribution channel, companies mark up the price of the product to cover business costs and operating profit. For refrigerators, refrigerator-freezers, 
and freezers, the main parties in the 
distribution chain are retailers, wholesalers, and general contractors. 
DOE developed baseline and 
incremental markups for each actor in 
the distribution chain. Baseline markups are applied to the price of products with baseline efficiency, while incremental markups are applied to the difference in price between baseline and higher-efficiency models (the incremental cost increase). The incremental markup is typically less than the baseline markup and is designed to maintain similar per-unit operating profit before and after new or amended standards.

DOE relied on economic data from the 
U.S. Census Bureau to estimate average baseline and incremental markups. Specifically, DOE used the 2017 Annual Retail Trade Survey for the ‘‘electronics and appliance stores’’ sector to develop retailer markups,
37the 2017 Annual 
Wholesale Trade Survey for the ‘‘household appliances, and electrical and electronic goods merchant wholesalers’’ sector to estimate wholesaler markups,
38and the industry 
series for the ‘‘residential building 
construction’’ sector published by the 2017 Economic Census to derive general contractor markups.

In response to the February 2023

(NAICS 443141). NOPR for Energy Conservation 
Standards for Residential Dishwashers. (AHAM, No. 69 at p. 15–16) 
DOE disagrees that the theory behind 
the concept of incremental markups is discredited. DOE’s incremental markup approach assumes that an increase in profitability, which is implied by keeping a fixed markup when the product price goes up, is unlikely to be viable over time in a reasonably competitive market like household appliance retailers. The Herfindahl- Hirschman Index (HHI) reported by the 2017 Economic Census indicates that household appliance stores sector (North American Industry Classification System (NAICS) code 443141) is a competitive marketplace.
43DOE 
recognizes that actors in the distribution chains are likely to seek to maintain the same markup on appliances in response to changes in manufacturer selling prices after an amendment to energy conservation standards. However, DOE believes that retail pricing is likely to adjust over time as those actors are forces to readjust their markups to reach a medium-term equilibrium in which per-unit profit is relatively unchanged before and after standards are implemented. 
DOE acknowledges that markup 
practices in response to amended standards are complex and varying with business conditions. However, DOE’s analysis necessarily considers a very simplified and hypothetical version of the world of appliance retailing: namely, a situation in which nothing changes except for those changes in appliance offerings that occur in response to amended standards. Obtaining data on markup practices in the situation described above is very challenging. Hence, DOE continues to believe that its assumption that standards do not facilitate a sustainable increase in profitability is reasonable.

provides details on DOE’s development of markups for refrigerators, refrigerator- freezers, and freezers. 
E. Energy Use Analysis 
The purpose of the energy use 
analysis is to determine the annual 
energy consumption of refrigerators, refrigerator-freezers, and freezers at different efficiencies in representative U.S. single-family homes, multi-family residences, and commercial buildings, and to assess the energy savings potential of increased product efficiency. The energy use analysis estimates the range of energy use of 
refrigerators, refrigerator-freezers, and freezers in the field (i.e., as they are 
actually used by consumers). The energy use analysis provides the basis for other analyses DOE performed, particularly assessments of the energy savings and the savings in consumer operating costs that could result from adoption of amended or new standards. 
The DOE test procedure produces 
standardized results that can be used to assess or compare the performance of products operating under specified conditions. Actual energy usage in the field often differs from that estimated by the test procedure because of variation in operating conditions, the behavior of users, and other factors. In the case of refrigerators, refrigerator-freezers, and freezers, DOE used usage adjustment factors (UAFs) in the February 2023 NOPR to address the difference in field- metered energy consumption and the DOE test results due to household- specific characteristics. 88 FR 12478– 12479. 
Specifically, DOE combined field- 
metered energy use data for full-size refrigeration products from the September 2011 Final Rule, the Northwest Energy Efficiency Alliance (‘‘NEEA’’), and the Florida Solar Energy Center (‘‘FSEC’’) with estimates of the test energy use of each field-metered unit. Then, DOE calculated a unit’s UAF by dividing the annual field-metered energy use by the annual energy consumption from the DOE test procedure. DOE then used maximum likelihood estimation to fit log-normal distributions to the empirical distributions of UAFs for primary refrigerators and refrigerator-freezers, secondary refrigerators and refrigerator- freezers, and freezers. DOE sampled UAFs from these fitted log-normal distributions to estimate the actual energy use of refrigeration products for the consumer sample. DOE did not have adequate field-metering data to derive UAFs for compact refrigeration products; therefore, DOE assumed the UAF of compact refrigeration products was 1.0. 
In response to the February 2023 
NOPR, AHAM commented that DOE relies heavily on the EIA’s Residential Energy Consumption Survey (‘‘RECS’’) data for estimating energy use and how 
consumption varies at the household level. Specifically, AHAM expressed concern that the use of RECS data to estimate energy consumption at the household level may introduce ‘‘outlier values,’’ resulting in uncertainty and inaccuracies (AHAM, No. 69 at pp. 17– 18) In this direct final rule, as well as in the February 2023 NOPR, DOE did not tie the energy consumption of 
refrigerators, refrigerator-freezers, and freezers to RECS survey data. 88 FR 12452. No household or demographic information from RECS affects the energy consumption of a particular household. Instead, as mentioned above, DOE sampled from distributions of UAFs that were derived from field- metering studies and assigned a randomly selected UAF to each household. Randomly sampling from distributions of UAFs acknowledges the inherent uncertainty in estimating the energy use for any particular household, while capturing the aggregate impact of UAFs measured in the field, and thus better approximates the most likely distribution of field energy use values across the installed base of products than relying strictly on survey data. DOE further notes, that AHAM is a party to the Joint Agreement and is supportive of the recommended standard adopted in this direct final rule. 
Chapter 7 of the direct final rule TSD 
provides details on DOE’s energy use analysis for refrigerators, refrigerator- freezers, and freezers. 
F. Life-Cycle Cost and Payback Period 
Analysis 
DOE conducted LCC and PBP 
analyses to evaluate the economic 
impacts on individual consumers of potential energy conservation standards for refrigerators, refrigerator-freezers, and freezers. The effect of new or amended energy conservation standards on individual consumers usually involves a reduction in operating cost and an increase in purchase cost. DOE used the following two metrics to measure consumer impacts: 
•The LCC is the total consumer 
expense of an appliance or product over the life of that product, consisting of total installed cost (manufacturer selling price, distribution chain markups, sales tax, and installation costs) plus operating costs (expenses for energy use, maintenance, and repair). To compute the operating costs, DOE discounts future operating costs to the time of purchase and sums them over the lifetime of the product. 
•The PBP is the estimated amount of 
time (in years) it takes consumers to recover the increased purchase cost (including installation) of a more efficient product through lower operating costs. DOE calculates the PBP by dividing the change in purchase cost at higher efficiency levels by the change in annual operating cost for the year that amended or new standards are assumed to take effect. 
For any given efficiency level, DOE 
measures the change in LCC relative to 
VerDate Sep<11>2014 19:16 Jan 16, 2024 Jkt 262001 PO 00000 Frm 00030 Fmt 4701 Sfmt 4700 E:\FR\FM\17JAR2.SGM 17JAR2lotter on DSK11XQN23PROD with RULES23055 Federal Register / Vol. 89, No. 11 / Wednesday, January 17, 2024 / Rules and Regulations 
the LCC in the no-new-standards case, 
which reflects the estimated efficiency distribution of refrigerators, refrigerator- freezers, and freezers in the absence of new or amended energy conservation standards. In contrast, the PBP for a given efficiency level is measured relative to the baseline product. 
For each considered efficiency level 
in each product class, DOE calculated the LCC and PBP for a nationally representative set of housing units (all product classes) and commercial buildings (PC 11A only). DOE included commercial applications in the analysis of compact refrigerators and refrigerator- freezers (PC 11A) because they are used in both the residential and commercial sectors (e.g., hotel rooms and higher- 
education dormitories). DOE developed household samples from the 2020 RECS and commercial building samples from the 2018 Commercial Buildings Energy Consumption Survey (‘‘CBECS’’). For each sample household or building, DOE determined the energy consumption for the refrigerator, refrigerator-freezer, or freezer and the appropriate electricity price and discount rate. By developing a 
representative sample of households and buildings, the analysis captured the variability in energy consumption, energy prices, and discount rates associated with the use of refrigerators, refrigerator-freezers, and freezers. 
Inputs to the calculation of total 
installed cost include the cost of the product—which includes MPCs, manufacturer markups, distribution chain markups, and sales taxes—and 
installation costs. Inputs to the calculation of operating expenses include annual energy consumption, energy prices and price projections, repair and maintenance costs, product lifetimes, and discount rates. DOE created distributions of values for product lifetime, discount rates, and sales taxes, with probabilities attached to each value, to account for their uncertainty and variability. 
The computer model DOE uses to 
calculate the LCC relies on a Monte Carlo simulation to incorporate uncertainty and variability into the analysis. The Monte Carlo simulations randomly sample input values from the probability distributions and refrigerator, refrigerator-freezer, and freezer user samples. For this rulemaking, the Monte Carlo approach is implemented in Python. The model calculated the LCC for products at each efficiency level for 10,000 housing units or commercial buildings per simulation run. The analytical results include a distribution of 10,000 data points showing the range of LCC savings for a given efficiency level relative to the no- new-standards case efficiency distribution. In performing an iteration of the Monte Carlo simulation for a given consumer, product efficiency is chosen based on its probability. If the chosen product efficiency is greater than or equal to the efficiency of the standard level under consideration, the LCC 
calculation reveals that a consumer is not impacted by the standard level. By accounting for consumers who already 
purchase more efficient products, DOE avoids overstating the potential benefits from increasing product efficiency. DOE calculated the LCC and PBP for consumers of refrigerators, refrigerator- freezers, and freezers as if each were to purchase a new product in the first year of required compliance with new or amended standards. For all TSLs other than TSL 4 (the Recommended TSL detailed in the Joint Agreement), any amended standards were assumed to apply to refrigerators, refrigerator- freezers, and freezers manufactured 3 years after the date on which any new or amended standard is published. (42 
U.S.C. 6295(m)(4)(A)(i)) Therefore, DOE used 2027 as the first year of compliance with any amended standards for refrigerators, refrigerator- freezers, and freezers for all TSLs other than TSL 4. For TSL 4, DOE used 2029 as the first year of compliance for representative PCs 5BI, 5A, 10, 11A, 17, and 18 and 2030 as the first year of compliance for the representative PCs 3, 5, 7, and 9, consistent with the Joint Agreement.

In response to the February 2023 
NOPR, an individual objected to the 
LCC analysis for two reasons: (1) future dollars savings are not the same as present-day dollars for purchase, which is especially problematic for low- income individuals; and (2) some in the elderly population would not live long enough to recover the incremental installed cost due to an amended standard, resulting in ‘‘age discrimination.’’ (Individual

manufacturing PPI series ID: PCU3352203352202. Available at www.bls.gov/ppi/. Commenter, No. 59 at p. 2) In regard to 
future dollar savings vs. present-day dollar savings for low-income households, DOE’s low-income consumer subgroup LCC analysis uses discount rates that are specific to low- income households, resulting in higher discount rates for these households, on average, compared to the full consumer sample used in the standard LCC analysis. See section IV.I of this document as well as chapter 11 of the direct final rule TSD for more details. In regard to the incremental installed cost for low-income consumers, DOE notes that many low-income consumers are renters who are typically not responsible for purchasing refrigeration equipment (see the discussion in section 
IV.I of this document as well as chapter11 of the direct final rule TSD).Moreover, the low-income subgroupresults indicate that low-incomehouseholds, on average, are expected toexperience higher LCC savings andlower payback periods than the generalpopulation (see the results in section
V.B.1.b of this document). In regard tosome individuals not living long enoughto recoup the incremental installed costdue to an amended standard, DOE notesthat even in such cases—which couldhappen to non-elderly consumers aswell—the equipment would continue toreap energy savings, but for a newowner. Therefore, DOE does not believethe LCC analysis discriminates againstelderly consumers relative to youngerconsumers in the general population.
AHAM commented that due to the 
skewed nature of the LCC savings results, DOE should report median values rather than mean values. (AHAM, No. 69 at p. 18) DOE notes that there are a variety of ways to characterize distributions of impacts, and DOE considers the impacts of a potential amended standard on refrigerators, refrigerator-freezers, and freezers holistically. DOE also notes that the median LCC savings for affected consumers are shown in the box-and- whisker plots in chapter 8 of the direct final rule TSD. 
AHAM also commented that DOE 
should be conducting a purchase decision analysis in its LCC model to reflect the actual conditions and expectations of the purchaser. (AHAM, No. 69 at p. 15) In the current setup of LCC analysis, DOE is not explicitly modeling the purchase decision made by purchasers when the standard becomes effective. DOE’s analysis is intended to model the range of individual outcomes likely to result from a hypothetical amended energy 
conservation standard at various levels of efficiency. DOE does not discount the consumer decision theory established in 
the broad behavioral economics field, but rather, notes that its methodological decision was made after considering the existence of various systematic market failures and their implication in rational versus actual purchase behavior. Furthermore, the outcome of the LCC is not considered in isolation, but in the context of the broader set of analyses, including the NIA. Moreover, the type of data required to facilitate a robust consumer choice modeling of a specific household appliance at the individual household level is currently lacking and AHAM did not provide much data. DOE further notes, that AHAM is a party to the Joint Agreement and is supportive of the recommended standard adopted in this direct final rule. 
1. Adjusted Volume Distribution
DOE developed adjusted volume
distributions within each PC containing 
more than one representative unit to determine the likelihood that a given purchaser would select each of the representative units for a given PC from the engineering analysis. DOE estimated the distribution of adjusted volumes for PC 3 and PC 5 based on the capacity distribution reported in the TraQline
® 
refrigerator data spanning from Q1 2018 to Q1 2019.
44DOE estimated the 
distribution of adjusted volumes for PC 11A based on the distribution of models from DOE’s Compliance Certification Management System (‘‘CCMS’’) Database. Table IV.10 presents the adjusted volume distribution of each of the PCs having more than one representative unit. DOE assumed that the adjusted volume distribution remains constant over the years considered in the analysis.

2. Product Cost
To calculate consumer product costs,
DOE multiplied the MPCs developed in the engineering analysis by the markups described previously (along with sales taxes). DOE used different markups for baseline products and higher-efficiency products, because DOE applies an incremental markup to the increase in MSP associated with higher-efficiency products. 
Economic literature and historical 
data suggest that the real costs of many products may trend downward over 
time according to ‘‘learning’’ or ‘‘experience’’ curves. Experience curve analysis implicitly includes factors such as efficiencies in labor, capital investment, automation, materials prices, distribution, and economies of scale at an industry-wide level.
45In the 
experience curve method, the real cost of production is related to the cumulative production or ‘‘experience’’ with a manufactured product. DOE used historical Producer Price Index (‘‘PPI’’) data for ‘‘household refrigerator and home freezer manufacturing’’ from the Bureau of Labor Statistics’ (‘‘BLS’’) spanning the time period between 1981 and 2022 as a proxy of the production cost for refrigerators, refrigerator- freezers and freezers.
46This is the most 
representative and current price index for refrigerators, refrigerator-freezers, and freezers. An inflation-adjusted price index was calculated by dividing the PPI series by the gross domestic product index from the Bureau of Economic Analysis for the same years. The cumulative production of refrigerators, refrigerator-freezers, and freezers were assembled from the annual shipments from the Association of Household Appliance Manufacturers (AHAM) between 1951 and 2022, and shipment estimates prior to 1951 using a trend analysis. The estimated learning rate (defined as the fractional reduction in price expected from each doubling of cumulative production) is 39.4 ±1.9 percent 
DOE included variable-speed 
compressors as a technology option for higher efficiency levels. To develop future prices specific for that technology, DOE applied a separate price trend to the controls portion of the variable-speed compressor, which represents part of the price increment when moving from an efficiency level achieved with the highest efficiency single-speed compressor to an efficiency

for further details on this topic. 
In response to the February 2023 
NOPR, AHAM commented that there is no theoretical underpinning for the implementation of an experience or learning curve and the functional form it should take. In addition, AHAM stated that the data that DOE used merely represents an empirical relationship, and a clear connection between the actual products in question and the data used needs to be made. AHAM noted that there is little reason to support the concept that price learning through manufacturing efficiencies should extend beyond the labor and materials in the product itself, and that such a relationship should not hold for other cost components. (AHAM, No. 69 at pp. 16–17) 
DOE notes that there is considerable 
empirical evidence of consistent price declines for appliances in the past few decades. Several studies examined refrigerator retail prices during different periods of time and showed that prices had been steadily falling while efficiency had been increasing, for example Dale, et al. (2009)
48and 
Taylor, et al. (2015).49As mentioned in 
Taylor and Fujita (2013),50Federal 
agencies have adopted different approaches to account for ‘‘the changing future compliance costs that might result from technological innovation or anticipated behavioral changes.’’ Given the limited data availability on historical manufacturing costs broken by different components, DOE utilized the Producer Price Index (‘‘PPI’’) published by the BLS as a proxy for manufacturing costs to represent the analyzed product as a whole. While products may experience varying degrees of price learning during different product stages, DOE modeled the average learning rate based on the full historical PPI series for ‘‘household refrigerator and home freezer manufacturing’’ to capture the overall price evolution in relation to the cumulative shipments. DOE also conducted sensitivity analyses that are 
based on a particular segment of the PPI data for household refrigerator manufacturing to investigate the impact of alternative product price projections (low price learning and high price learning) in the NIA of this direct final rule. DOE further notes, that AHAM is a party to the Joint Agreement and is supportive of the recommended standard adopted in this direct final rule. 
3. Installation Cost
Installation cost includes labor,
overhead, and any miscellaneous 
materials and parts needed to install the product. DOE found no evidence that installation costs for refrigerators, refrigerator-freezers, and freezers would be impacted with increased efficiency levels. As a result, DOE did not include installation costs in the LCC and PBP analysis. 
4. Annual Energy Consumption
For each sampled household or
commercial building, DOE determined 
the energy consumption for a refrigerator, refrigerator-freezer, or freezer at different efficiency levels using the approach described previously in section IV.E of this document. 
5. Energy Prices
Because marginal electricity price
more accurately captures the 
incremental savings associated with a change in energy use from higher efficiency, it provides a better representation of incremental change in consumer costs than average electricity prices. Therefore, DOE applied average electricity prices for the energy use of the product purchased in the no-new- standards case, and marginal electricity prices for the incremental change in energy use associated with the other efficiency levels considered. 
DOE derived electricity prices in 2022 
using data from EEI Typical Bills and Average Rates reports. Based upon comprehensive, industry-wide surveys, this semi-annual report presents typical monthly electric bills and average kilowatt-hour costs to the customer as charged by investor-owned utilities. For the residential sector, DOE calculated electricity prices using the methodology described in Coughlin and Beraki (2018).
51For the commercial sector, 
DOE calculated electricity prices using the methodology described in Coughlin and Beraki (2019).
52 
To estimate energy prices in future 
years, DOE multiplied the 2022 energy prices by the projection of annual average price changes for each of the nine census divisions from the Reference case in AEO2023, which has an end year of 2050.
53To estimate price 
trends after 2050, DOE used the 2050 electricity prices, held constant. 
6. Maintenance and Repair Costs
Repair costs are associated with
repairing or replacing product 
components that have failed in an appliance; maintenance costs are associated with maintaining the operation of the product. Typically, small incremental increases in product efficiency entail no, or only minor, changes in repair and maintenance costs compared to baseline efficiency products. DOE is not aware of any data that suggest the cost of maintenance changes as a function of efficiency for refrigerators, refrigerator-freezers, and freezers. DOE therefore assumed that maintenance costs are the same regardless of EL and do not impact the LCC or PBP. 
For the February 2023 NOPR as well 
as this direct final rule, DOE developed a repair cost estimation method based on the average total installed cost and average annual repair costs by PC and EL from the September 2011 Final Rule. For each of three categories—standard- size refrigerator-freezers, standard-size freezers, and compact refrigeration products—DOE averaged the annual repair cost as a fraction of the total installed cost at each EL. Based on this method, DOE estimated consumers with standard-size refrigerator-freezers have annual repair costs equal to 1.8 percent of their total installed cost, consumers

consumer purchase decision between two otherwise identical goods with different first cost and operating cost. It is the interest rate that equates the increment of first cost to the difference in net present value of lifetime operating cost, incorporating the influence of several factors: transaction costs; risk premiums and response to uncertainty; time preferences; interest rates at which a consumer is able to borrow or lend. The implicit discount rate is not appropriate for the LCC analysis because it reflects a range of factors that influence consumer purchase decisions, rather than the opportunity cost of the funds that are used in purchases.

System. Survey of Consumer Finances. 1995, 1998, 2001, 2004, 2007, 2010, 2013, 2016, and 2019. Available at www.federalreserve.gov/econresdata/ scf/scfindex.htm (last accessed July 10, 2023). with standard-size freezers have an 
annual repair cost of 0.8 percent of their total installed cost, and consumers with compact refrigeration products have an annual repair cost of 0.9 percent of their total installed cost. Because high- efficiency products have a higher installed cost, their estimated average annual repair costs are also higher. 
In response to the February 2023 
NOPR, an individual commented that product reliability is inversely related to the number of product parts, and Strauch suggested that DOE use the MIL–HDBK–217 or the Bellcore/ Telcordia reliability guides to inform its maintenance and repair cost analysis. (Individual Commenter, No. 59 at pp. 1– 2) DOE appreciates the recommendation, but notes that the data required to properly use the MIL– HDBK–217 or Bellcore/Telcordia standards
54(e.g., parts count, parts 
stress conditions, and laboratory and field failure rates of specific parts) is unavailable in the LCC analysis. This is due to the fact that the LCC analyzes refrigerator, refrigerator-freezer, and freezer representative units as opposed to specific product models. Moreover, according to Hottinger Bru ¨el & Kj#r 
(‘‘HBK’’) there are a number of limitations to such empirical methods, including: (1) the data used to inform these traditional empirical models is typically outdated, (2) whereas the models assume components fail independently of each other, in some 
cases the overall system design is the causal factor, and (3) obtaining high- quality field and manufacturing data to inform the adjustment factors used in the models is difficult.
55For these 
reasons, for this direct final rule analysis DOE continued to use the method used in the February 2023 NOPR. 
AHAM also commented that failed 
VIPs are unrepairable in the field meaning manufacturers work to ensure VIPs will not fail prior to the end of the product’s useful life. (AHAM, No. 69 at p. 6) DOE appreciates this information but notes that, due to a lack of available data, the repair cost estimates used in the LCC analysis are not component- specific. 7. Product Lifetime 
DOE performed separate modeling of 
lifetime for standard-size refrigerators and refrigerator-freezers, standard-size freezers, and compact refrigeration products. For standard-size refrigerators, refrigerator-freezers, and freezers, DOE estimated product lifetimes by fitting a survival probability function to data on historical shipments and the age distributions of installed stock from RECS 2005, RECS 2009, RECS 2015, and RECS 2020. The survival function, which DOE assumed has the form of a cumulative Weibull distribution, provides an average and median lifetime. Moreover, the conversion from primary-to-secondary refrigerator or refrigerator-freezer was also modeled as part of the lifetime determination for standard-size refrigerators and refrigerator-freezers. 
For compact refrigerators, DOE 
estimated an average lifetime of 8.8 years using data on shipments and the number of units in use (stock). For compact freezers, DOE did not have reliable stock data available to compare against historical shipments. Therefore, DOE estimated an average lifetime of 11.3 years by multiplying the average lifetime of compact refrigerators by the ratio of the average lifetime of standard- size freezers (18.4 years) to the average lifetime of standard-size refrigerators and refrigerator-freezers (14.3 years). 
In response to the February 2023 
NOPR, an individual commented that more stringent efficiency standards reduce the service lifetime of refrigerators, refrigerator-freezers, and freezers. (Individual Commenter, No. 59 at p. 1) DOE used the latest available data to inform the lifetime distributions used in this direct final rule analysis, and DOE does not have data to corroborate a causal connection between the stringency of efficiency standards and the expected service lifetime of refrigerators, refrigerator-freezers, and freezers. Therefore, DOE continues to assume that amending the efficiency standards for refrigerators, refrigerator- freezers, and freezers will not directly impact the estimated service lifetime of these products. 
8. Discount Rates 
In the calculation of LCC, DOE 
applies discount rates appropriate to 
residential and commercial consumers to estimate the present value of future operating cost savings. DOE estimated distributions of residential and commercial discount rates for refrigerators, refrigerator-freezers, and freezers based on consumer financing costs and the opportunity cost of consumer funds (for the residential sector) and cost of capital of publicly traded firms (for the commercial sector). 
DOE applies weighted average 
discount rates calculated from consumer debt and asset data, rather than marginal or implicit discount rates.
56The LCC 
analysis estimates net present value over the lifetime of the product, so the appropriate discount rate will reflect the general opportunity cost of household funds, taking this time scale into account. Given the long time horizon modeled in the LCC, the application of a marginal interest rate associated with an initial source of funds is inaccurate. Regardless of the method of purchase, consumers are expected to continue to rebalance their debt and asset holdings over the LCC analysis period, based on the restrictions consumers face in their debt payment requirements and the relative size of the interest rates available on debts and assets. DOE estimates the aggregate impact of this rebalancing using the historical distribution of debts and assets. 
To establish residential discount rates 
for the LCC analysis, DOE identified all relevant household debt or asset classes in order to approximate a consumer’s opportunity cost of funds related to appliance energy cost savings. It estimated the average percentage shares of the various types of debt and equity by household income group using data from the Federal Reserve Board’s triennial Survey of Consumer Finances
57(‘‘SCF’’) starting in 1995 and 
ending in 2019. Using the SCF and other sources, DOE developed a distribution of rates for each type of debt and asset by income group to represent the rates that may apply in the year in which amended standards would take effect. DOE assigned each sample household a specific discount rate drawn from one of the distributions. The average rate across all types of household debt and equity and income groups, weighted by the shares of each type, is

approximately 4 percent (the average 
varies by PC). 
For commercial consumers, DOE used 
the cost of capital to estimate the present value of cash flows to be derived from a typical company project or investment. Most companies use both debt and equity capital to fund investments, so the cost of capital is the weighted-average cost to the firm of equity and debt financing. This corporate finance approach is referred to as the weighted-average cost of capital. DOE used currently available economic data in developing discount rates. The average discount rate for the PC 11A commercial consumer sample is 6.8 percent. 
In response to the February 2023 
NOPR, AHAM commented that operating costs and the depreciation of capital investments are deductible costs for commercial end-users from Federal and State corporate income taxes. AHAM suggested that DOE should incorporate the effects of tax deductibility in the LCC analysis. (AHAM, No. 69 at p. 19) DOE responds that as noted in the comment, the estimation of commercial discount rates accounts for the tax deductibility of the energy costs and capital investment depreciation and therefore the net present value of the future operating cost savings in the LCC analysis should already reflect that effect. 
In response to the February 2023 
NOPR, AHAM further commented that DOE used an inappropriate discount rate in its analysis of the effects of standards on low-income households, claiming that it does not take into account issues of capital availability or the non-financial costs from a purchase. AHAM also presented data from their survey work with Bellomy Research showing that the lowest 30 percent income groups have no discretionary income to save, making it impossible for them to rebalance their balance sheets after making a purchase. (AHAM, No. 69 at p. 11) 
With respect to the issue of DOE’s 
methodology for estimating consumer discount rates, DOE maintains that the LCC is not predicting a purchase decision, which DOE assumes to be AHAM’s interpretation given their focus on the availability of cash for appliance purchases. Rather, the LCC estimates the net present value of the financial impact of a given standard level over the lifetime of the product (i.e., 30 years) 
assuming the standard-compliant product has already been installed and allows for comparison of this value across different hypothetical minimum efficiency levels. It is applied to future- year energy costs and non-energy operations and maintenance costs in order to calculate the net present value of the appliance to a household at the time of installation. The consumer discount rate reflects the opportunity cost of receiving energy cost savings in the future, rather than at the time of purchase and installation. The opportunity cost of receiving operating cost savings in future years, rather than in the first year of the modeled period, is dependent on the rate of return that could be earned if invested into an interest-bearing asset or the interest cost accrual avoided by paying down debt. Consumers in all income bins generally hold a variety of assets (e.g., certificates 
of deposit, stocks, bonds) and debts (e.g., mortgage, credit cards, vehicle 
loan), which vary in amount over time as consumers allocate their earnings, make new investments, etc. Thus, the consumer discount rate is estimated as a weighted average of the rates and proportions of the various types of assets and debts held by households in a given income bin, as reported by the Survey of Consumer Finances. In the low-income subgroup analysis, DOE specifically evaluated the impacts of increased efficiency on low-income households using discount rates estimated specifically for the low- income bin. DOE further notes, that AHAM is a party to the Joint Agreement and is supportive of the recommended standard adopted in this direct final rule. 
See chapter 8 of the direct final rule 
TSD for further details on the development of consumer discount rates. 
9. Energy Efficiency Distribution in the 
No-New-Standards Case 
To accurately estimate the share of 
consumers that would be affected by a potential energy conservation standard at a particular efficiency level, DOE’s LCC analysis considered the projected distribution (market shares) of product efficiencies under the no-new-standards case (i.e., the case without amended or 
new energy conservation standards). 
To estimate the energy efficiency 
distribution of refrigerators, refrigerator- freezers, and freezers, DOE used current shipments data provided by AHAM in response to the NOPR for PCs 3, 5, 5A, 7, 9, 11A, and 18, and model counts from DOE’s CCMS database for PCs 5BI, 10, and 17. (AHAM, No. 69 at pp. 2–3) Models in the database were categorized by capacity and assigned an efficiency level based on reported energy use. In the absence of data on trends in efficiency, DOE assumed the current efficiency distribution would be representative of the efficiency distribution in the compliance year in the no-new-standards case. The estimated market shares for the no-new- standards case for refrigerators, refrigerator-freezers, and freezers are shown in Table IV.11. See chapter 8 of 
the direct final rule TSD for further information on the derivation of the efficiency distributions.

www.journals.uchicago.edu/doi/full/10.1086/ 686252) (last accessed August 1, 2023). The LCC Monte Carlo simulations 
draw from the efficiency distributions 
and randomly assign an efficiency to the refrigerator, refrigerator-freezer, or freezer purchased by each sample household in the no-new-standards case. The resulting percent shares within the sample match the market shares in the efficiency distributions. 
In the February 2023 NOPR, DOE 
performed a random assignment of efficiency levels to consumers in its Monte Carlo sample. 88 FR 12452, 12484–12485. While DOE acknowledges that economic factors may play a role when consumers decide on what type of refrigerator, refrigerator-freezer, or freezer to install, assignment of refrigeration product efficiency for a given installation, based solely on economic measures such as life-cycle cost or simple payback period, most likely would not fully and accurately reflect actual real-world installations. There are a number of market failures discussed in the economics literature that illustrate how purchasing decisions with respect to energy efficiency are unlikely to be perfectly correlated with energy use, as described below. DOE maintains that the method of assignment, which is in part random, is a reasonable approach, because it simulates behavior in the refrigeration product market, where market failures result in purchasing decisions not being perfectly aligned with economic interests, and is more realistic than relying only on apparent cost- effectiveness criteria derived from the limited information in RECS. DOE further emphasizes that its approach does not assume that all purchasers of refrigeration products make economically irrational decisions (i.e., the lack of a correlation is not the same as a negative correlation). By using this approach, DOE acknowledges the uncertainty inherent in the data and minimizes any bias in the analysis by using random assignment, as opposed to assuming certain market conditions that are unsupported given the available evidence. 
The following discussion provides 
more detail about the various market failures that affect refrigeration product purchases. First, consumers are motivated by more than simple financial trade-offs. There are consumers who are willing to pay a premium for more energy-efficient products because they are environmentally conscious.
58There are also several behavioral factors that 
can influence the purchasing decisions of complicated multi-attribute products, such as refrigeration products. For example, consumers (or decision makers in an organization) are highly influenced by choice architecture, defined as the framing of the decision, the surrounding circumstances of the purchase, the alternatives available, and how they are presented for any given choice scenario.
59The same consumer 
or decision maker may make different choices depending on the characteristics of the decision context (e.g., the timing 
of the purchase, competing demands for funds), which have nothing to do with the characteristics of the alternatives themselves or their prices. Consumers or decision makers also face a variety of other behavioral phenomena including loss aversion, sensitivity to information salience, and other forms of bounded rationality.
60Thaler, who won the 
Nobel Prize in Economics in 2017 for his contributions to behavioral economics, and Sunstein point out that these behavioral factors are strongest when the decisions are complex and infrequent, when feedback on the decision is muted and slow, and when there is a high degree of information asymmetry.
61These characteristics 
describe almost all purchasing situations of appliances and equipment, including refrigerators, refrigerator- freezers, and freezers. The installation of a new or replacement refrigeration products is done very infrequently, as evidenced by the mean lifetime of 14.3 years for standard-size refrigerators and refrigerator-freezers and 18.4 years for standard-size freezers. Further, if the purchaser of the refrigerator, refrigerator-freezer, or freezer is not the entity paying the energy costs (e.g., a 
building owner and tenant), there may be little to no feedback on the purchase. Additionally, there are systematic market failures that are likely to contribute further complexity to how products are chosen by consumers, as explained in the following paragraphs. The first of these market failures—the 
split-incentive or principal-agent problem—is likely to significantly affect refrigerators, refrigerator-freezers, and freezers. The principal-agent problem is a market failure that results when the consumer that purchases the equipment does not internalize all of the costs associated with operating the equipment. Instead, the user of the product, who has no control over the purchase decision, pays the operating costs. There is a high likelihood of split- incentive problems in the case of rental properties where the landlord makes the choice of what refrigeration product to install, whereas the renter is responsible for paying energy bills. 
In addition to the split-incentive 
problem, there are other market failures that are likely to affect the choice of refrigerator, refrigerator-freezer, or freezer product efficiency made by consumers. For example, unplanned replacements due to unexpected failure of equipment such as refrigeration products are strongly biased toward like-for-like replacement (i.e., replacing 
the non-functioning equipment with a similar or identical product). Time is a constraining factor during unplanned replacements, and consumers may not consider the full range of available options on the market, despite their availability. The consideration of alternative product options is far more likely for planned replacements and installations in new construction. 
Additionally, Davis and Metcalf
62 
conducted an experiment demonstrating that, even when consumers are presented with energy consumption information, the nature of the information available to consumers (e.g., from EnergyGuide labels) results in an inefficient allocation of energy efficiency across households with different usage levels. Their findings indicate that households are likely to make decisions regarding the efficiency of the air conditioning equipment of their homes that do not result in the highest net present value for their specific usage pattern (i.e., their 
decision is based on imperfect information and, therefore, is not necessarily optimal). Also, most consumers did not properly understand the labels (specifically whether energy consumption and cost estimates were national averages or specific to their

a proxy for national sales, as aggregate data on sales are lacking. In general, one would expect a close correspondence between shipments and sales. State). As such, consumers did not make 
the most informed decisions. 
In part because of the way 
information is presented, and in part because of the way consumers process information, there is also a market failure consisting of a systematic bias in the perception of equipment energy usage, which can affect consumer choices. Attari et al.
63show that 
consumers tend to underestimate the energy use of large energy-intensive appliances (such as air conditioners, dishwashers, and clothes dryers), but overestimate the energy use of small appliances (such as light bulbs). Therefore, it is possible that consumers systematically underestimate the energy use associated with refrigerators, refrigerator-freezers, and freezers, resulting in less cost-effective purchases. 
These market failures affect a sizeable 
share of the consumer population. A study by Houde
64indicates that there is 
a significant subset of consumers that appear to purchase appliances without taking into account their energy efficiency and operating costs at all. 
The existence of market failures in the 
residential sector is well supported by the economics literature and by a number of case studies. If DOE developed an efficiency distribution that assigned refrigeration product efficiency in the no-new-standards case solely according to energy use or economic considerations such as life- cycle cost or payback period, the resulting distribution of efficiencies within the consumer sample would not reflect any of the market failures or behavioral factors above. Thus, DOE concludes such a distribution would not be representative of the refrigeration 
product market. Further, even if a specific household is not subject to the market failures above, the purchasing decision of refrigerator, refrigerator- freezer, or freezer product efficiency can be highly complex and influenced by a number of factors (e.g., aesthetics) not 
captured by the building characteristics available in the RECS sample. These factors can lead to households or building owners choosing a refrigeration product efficiency that deviates from the efficiency predicted using only energy use or economic considerations such as 
life-cycle cost or payback period. 
There is a complex set of behavioral 
factors, with sometimes opposing effects, affecting the refrigeration product market. It is impractical to model every consumer decision incorporating all of these effects at this extreme level of granularity given the limited available data. Given these myriad factors, DOE estimates the resulting distribution of such a model, if it were possible, would be very scattered with high variability. It is for this reason DOE utilizes a random distribution (after accounting for efficiency market share constraints) to approximate these effects. The methodology is not an assertion of economic irrationality, but instead, it is a methodological approximation of complex consumer behavior. The analysis is neither biased toward high or low energy savings. The methodology does not preferentially assign lower- efficiency refrigeration products to households in the no-new-standards case where savings from the rule would be greatest, nor does it preferentially assign lower-efficiency refrigeration products to households in the no-new- standards case where savings from the rule would be smallest. Some consumers were assigned the refrigeration products that they would have chosen if they had engaged in perfect economic considerations when purchasing the products. Others were assigned less-efficient refrigeration products even where a more-efficient product would eventually result in life- cycle savings, simulating scenarios where, for example, various market failures prevent consumers from realizing those savings. Still others were assigned refrigeration products that 
were more efficient than one would 
expect simply from life-cycle costs analysis, reflecting, say, ‘‘green’’ behavior, whereby consumers ascribe independent value to minimizing harm to the environment. 
10. Payback Period Analysis 
The payback period is the amount of 
time (expressed in years) it takes the 
consumer to recover the additional installed cost of more efficient products, compared to baseline products, through energy cost savings. Payback periods that exceed the life of the product mean that the increased total installed cost is not recovered in reduced operating expenses. 
The inputs to the PBP calculation for 
each efficiency level are the change in total installed cost of the product and the change in the first-year annual operating expenditures relative to the baseline. DOE refers to this as a ‘‘simple PBP’’ because it does not consider changes over time in operating cost savings. The PBP calculation uses the same inputs as the LCC analysis when deriving first-year operating costs. 
As noted previously, 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 first year’s energy savings resulting from the standard, as calculated under the applicable test procedure. (42 U.S.C. 6295(o)(2)(B)(iii)) For each considered efficiency level, DOE determined the value of the first year’s energy savings by calculating the energy savings in accordance with the applicable DOE test procedure, and multiplying those savings by the average energy price projection for the year in which compliance with the amended standards would be required. 
G. Shipments Analysis 
DOE uses projections of annual 
product shipments to calculate the 
national impacts of potential amended or new energy conservation standards on energy use, NPV, and future manufacturer cash flows.
65The 
shipments model takes an accounting approach, tracking market shares of each product class and the vintage of units in the stock. Stock accounting uses product shipments as inputs to estimate the age distribution of in-service product stocks for all years. The age distribution of in-service product stocks is a key input to calculations of both the NES and NPV, because operating costs for any year depend on the age distribution of the stock. For this direct final rule, DOE excluded PC 9A—BI from the shipments analysis due to its very small shipments volume. 
Total shipments for each product 
category (i.e., standard-size refrigerators 
and refrigerator-freezers, standard-size freezers, compact refrigerators and refrigerator-freezers, and compact freezers) are developed by considering the demand from various market segments. For standard-size refrigerators and refrigerator-freezers, DOE considered demand from replacements for units in stock that fail, shipments to new construction, and the demand created by increased saturation into existing households corresponding to

secondary unit. For all other product categories, DOE considered demand from replacements for units in stock that fail, shipments to new construction, and shipments to first-time owners in existing households. DOE calculated shipments due to replacements using the retirement functions developed for the LCC analysis (see chapter 8 of the 
direct final rule TSD for details). DOE projected shipments to new construction using estimates for new housing starts and the average saturation of each product category in new households. Shipments to first-time owners were estimated by analyzing the increasing penetration of products into existing households in each product category. For standard-size refrigerators and refrigerator-freezers, DOE estimated shipments from increased saturation corresponding to the conversion of a primary unit to a secondary unit utilizing the primary-to-secondary conversion function developed for the LCC analysis. More detail on this methodology can be found in chapter 8 of the direct final rule TSD. 
For the direct final rule analysis, DOE 
incorporated data from stakeholders into the shipments. Confidential aggregate historical shipments data from 2015–2022 provided by AHAM were used to calibrate the total shipments for standard-size refrigerator-freezers, compact refrigerators, upright freezers, chest freezers, and built-in refrigerator- freezers. For the direct final rule, DOE used the AHAM-provided estimates for the efficiency distributions based on shipments for standard-size refrigerator- freezers and compact freezers. (AHAM, No. 69 at pp. 2–3) Whirlpool requested that DOE 
provide data to indicate that there would be no impact to appliance replacement at the proposed standard level at TSL 5. (Whirlpool, No. 85 at pp. 8–9) DOE uses a price elasticity of demand to address the impact of increased prices on shipments based on an analysis using market-level appliance data including refrigerators.
66DOE 
provides the description of the price elasticity methodology in chapter 9 in the direct final rule TSD.

H. National Impact Analysis 
The NIA assesses the national energy 
savings (‘‘NES’’) and the NPV from a 
national perspective of total consumer costs and savings that would be expected to result from new or amended standards at specific efficiency levels.
67 
(‘‘Consumer’’ in this context refers to consumers of the product being regulated.) DOE calculates the NES and NPV for the potential standard levels considered based on projections of annual product shipments, along with the annual energy consumption and total installed cost data from the energy use and LCC analyses. For the present analysis, DOE projected the energy savings, operating cost savings, product costs, and NPV of consumer benefits over the lifetime of refrigerators, refrigerator-freezers, and freezers sold from 2027 through 2056 for all TSLs other than TSL 4, the Recommended TSL detailed in the Joint Agreement. For TSL 4, DOE projected the energy savings, operating cost savings, product costs, and NPV of consumer benefits over the lifetime of refrigerators, refrigerator-freezers, and freezers sold from 2029 through 2058 for the product classes listed in Table I.1 and 2030 through 2059 for the product classes listed in Table I.2. 
DOE evaluates the impacts of new or 
amended standards by comparing a case without such standards with standards- case projections. The no-new-standards case characterizes energy use and consumer costs for each product class in the absence of new or amended energy conservation standards. For this projection, DOE considers historical trends in efficiency and various forces that are likely to affect the mix of efficiencies over time. DOE compares the no-new-standards case with projections characterizing the market for each product class if DOE adopted new or amended standards at specific energy efficiency levels (i.e., the TSLs or 
standards cases) for that class. For the standards cases, DOE considers how a given standard would likely affect the market shares of products with efficiencies greater than the standard. 
DOE uses a spreadsheet model, which 
is available in the docket, to calculate the energy savings and the national consumer costs and savings from each TSL. Interested parties can review DOE’s analyses by changing various input quantities within the spreadsheet. The NIA spreadsheet model uses typical values (as opposed to probability distributions) as inputs. 
Table IV.12 summarizes the inputs 
and methods DOE used for the NIA analysis for the direct final rule. Discussion of these inputs and methods follows the table. See chapter 10 of the

Available at www.eia.gov/forecasts/aeo/index.cfm (last accessed July 13, 2023). 1. Product Efficiency Trends 
A key component of the NIA is the 
trend in energy efficiency projected for 
the no-new-standards case and each of the standards cases. Section IV.F.9 of this document describes how DOE developed an energy efficiency distribution for the no-new-standards case (which yields a shipment-weighted average efficiency) for each of the considered product classes for the year of anticipated compliance with an amended or new standard. 
For the standards cases, DOE used a 
‘‘roll up’’ scenario to establish the shipment-weighted efficiency for the year that standards are assumed to become effective. In this scenario, the market shares of products in the no- new-standards case that do not meet the standard under consideration would ‘‘roll up’’ to meet the new standard level, and the market share of products above the standard would remain unchanged. In the absence of data on trends in efficiency, DOE assumed no efficiency trend over the analysis period for both the no-new-standards and standards cases. For a given case, market shares by efficiency level were held fixed to their distribution in the compliance year. The approach is further described in chapter 10 of the direct final rule TSD. 
2. National Energy Savings 
The national energy savings analysis 
involves a comparison of national 
energy consumption of the considered products between each potential standards case (‘‘TSL’’) and the case with no new or amended energy conservation standards. DOE calculated the national energy consumption by multiplying the number of units (stock) of each product (by vintage or age) by the unit energy consumption (also by vintage). DOE calculated annual NES based on the difference in national energy consumption for the no-new- standards case and for each higher efficiency standard case. DOE estimated energy consumption and savings based on site energy and converted the electricity consumption and savings to primary energy (i.e., the energy 
consumed by power plants to generate site electricity) using annual conversion factors derived from AEO2023. Cumulative energy savings are the sum of the NES for each year over the timeframe of the analysis. 
In this direct final rule analysis, DOE 
analyzed the energy and economic impacts of a potential standard on all product classes in the scope of refrigerators, refrigerator-freezers, and freezers. Results for non-representative product classes (i.e., those not analyzed 
in the engineering, energy use, and LCC 
analyses) are scaled using results for the analyzed product class that best represents each non-representative product class. For non-representative freestanding product classes, energy use values are scaled by applying the ratio of the current Federal standard baseline between the two product classes at a fixed volume. For non-representative built-in product classes, DOE developed energy scalars using the most similar freestanding representative product class and assumed a 5-percent reduction in the increase in efficiency at each EL relative to the corresponding EL for the freestanding product class. For example, a 10-percent reduction in energy use for PC 3 would correspond to a 5-percent reduction for PC 3–BI. DOE assumes the incremental cost between efficiency levels is the same for representative and non-representative product classes. See chapter 10 of the direct final rule TSD for more details. 
In this direct final rule, for the 
Recommended TSL (TSL 4), the scaling of certain non-representative product classes (specifically PC 12, PC 4–BI, PC 7–BI, and PC 9–BI) has been modified from the February 2023 NOPR, consistent with the Joint Agreement. In the February 2023 NOPR, PC 12 was scaled to PC 11A with the same standard level for PC 12 as PC 11A under a given TSL. However, under the Joint Agreement, at the Recommended TSL, PC 12 is scaled differently. At TSL 4, for PC 11A, the standard is met at EL 2 and for PC 12, the standard level corresponds to EL 1 for PC 11A. Thus, for TSL 4, DOE updated its scaling for PC 12 to reflect EL 1 rather than EL 2 from PC 11A. In the February 2023 NOPR, PC 4–BI and PC 7–BI were scaled to PC 7, and the standard level under TSL 4 corresponded to EL 3 for PC 4– BI, PC 7–BI, and PC 7. Under the Joint Agreement, at TSL 4, PC 7 continues to correspond to EL 3, but PC 4–BI and PC 7–BI correspond to EL 4. Finally, in the February 2023 NOPR, PC 9—BI was scaled to PC 9, and both met the standard under TSL 4 at EL1. At TSL4, the standard for PC 9 is met at EL 2 while PC–9 BI continues to be scaled to EL 1. 
Use of higher-efficiency products is 
sometimes associated with a direct rebound effect, which refers to an increase in utilization of the product due to the increase in efficiency. DOE did not find any data on the rebound effect specific to refrigerators that would indicate that consumers would alter their utilization of their product as a 
result of an increase in efficiency. DOE assumed a rebound rate of 0. DOE did not receive any comments regarding this 
assumption in response to the February 2023 NOPR. 
In 2011, in response to the 
recommendations of a committee on ‘‘Point-of-Use and Full-Fuel-Cycle Measurement Approaches to Energy Efficiency Standards’’ appointed by the National Academy of Sciences, DOE announced its intention to use FFC measures of energy use and greenhouse gas and other emissions in the national impact analyses and emissions analyses included in future energy conservation standards rulemakings. 76 FR 51281 (Aug. 18, 2011). After evaluating the approaches discussed in the August 18, 2011 statement of policy, DOE published a statement of amended policy in which DOE explained its determination that EIA’s National Energy Modeling System (‘‘NEMS’’) is the most appropriate tool for its FFC analysis and its intention to use NEMS for that purpose. 77 FR 49701 (Aug. 17, 2012). NEMS is a public domain, multi- sector, partial equilibrium model of the U.S. energy sector
68that EIA uses to 
prepare its Annual Energy Outlook. The FFC factors incorporate losses in production and delivery in the case of natural gas (including fugitive emissions) and additional energy used to produce and deliver the various fuels used by power plants. The approach used for deriving FFC measures of energy use and emissions is described in appendix 10B of the direct final rule TSD. 
3. Net Present Value Analysis 
The inputs for determining the NPV 
of the total costs and benefits 
experienced by consumers are (1) total annual installed cost, (2) total annual operating costs (energy costs and repair and maintenance costs), and (3) a discount factor to calculate the present value of costs and savings. DOE calculates net savings each year as the difference between the no-new- standards case and each standards case in terms of total savings in operating costs versus total increases in installed costs. DOE calculates operating cost savings over the lifetime of each product shipped during the projection period. 
As discussed in section IV.F.2 of this 
document, DOE developed refrigerators, refrigerator-freezers, and freezers price trends based on an experience curve calculated using historical PPI data. For efficiency levels with a single-speed compressor, DOE applied a price trend

Budget. Circular A–4: Regulatory Analysis.

georgewbush-whitehouse.archives.gov/omb/memoranda/m03-21.html (last accessed July 10, 2023). developed using the ‘‘household 
refrigerator and home freezer manufacturing’’ PPI to the entire cost of the unit. For efficiency levels with a variable-speed compressor, DOE applied a price trend developed from the ‘‘semiconductors and related device manufacturing’’ PPI to the cost associated with the electronics used to control the variable-speed compressor and the same price trend used for single-speed compressor units to the non-controls portion of the cost of the unit. By 2059, which is the end date of the projection period for the Recommended TSL detailed in the Joint Agreement, the average single-speed compressor refrigerators, refrigerator- freezers, and freezers price is projected to drop 33-percent relative to 2030. DOE’s projection of product prices is described in chapter 8 of the direct final rule TSD. 
To evaluate the effect of uncertainty 
regarding the price trend estimates, DOE investigated the impact of different product price projections on the consumer NPV for the considered TSLs for refrigerators, refrigerator-freezers, and freezers. In addition to the default price trend, DOE considered two product price sensitivity cases: For the single-speed compressor refrigerators, refrigerator-freezers, and freezers and the non-variable-speed controls portion of refrigerators, refrigerator-freezers, and freezers, DOE estimated the high-price- decline and the low-price-decline scenarios based on household refrigerator and home freezer PPI data limited to the period between the period 1981–2008 and 2009–2021, respectively. For the variable-speed controls portion of refrigerators, refrigerator-freezers, and freezers, DOE estimated the high-price- decline and the low-price-decline scenarios based on an exponential trend line fit of the semiconductor PPI between the period 1994–2021 and 1967–1993, respectively. The derivation of these price trends and the results of these sensitivity cases are described in appendix 10C of the direct final rule TSD. 
The energy cost savings are calculated 
using the estimated energy savings in each year and the projected price of the appropriate form of energy. To estimate energy prices in future years, DOE multiplied the average regional energy prices by the projection of annual national-average residential energy price changes in the Reference case from AEO2023, which has an end year of 
2050. To estimate price trends after 2050, the 2046–2050 average was used for all years. As part of the NIA, DOE 
also analyzed scenarios that used inputs from variants of the AEO2023 Reference case that have lower and higher 
economic growth. Those cases have lower and higher energy price trends compared to the Reference case. NIA results based on these cases are presented in appendix 10C of the direct final rule TSD. 
In calculating the NPV, DOE 
multiplies the net savings in future years by a discount factor to determine their present value. For this direct final rule, DOE estimated the NPV of consumer benefits using both a 3- percent and a 7-percent real discount rate. DOE uses these discount rates in accordance with guidance provided by the Office of Management and Budget (‘‘OMB’’) to Federal agencies on the development of regulatory analysis.
69 
The discount rates for the determination of NPV are in contrast to the discount rates used in the LCC analysis, which are designed to reflect a consumer’s perspective. The 7-percent real value is an estimate of the average before-tax rate of return to private capital in the U.S. economy. The 3-percent real value represents the ‘‘social rate of time preference,’’ which is the rate at which society discounts future consumption flows to their present value. 
I. Consumer Subgroup Analysis 
In analyzing the potential impact of 
new or amended energy conservation 
standards on consumers, DOE evaluates the impact on identifiable subgroups of consumers that may be disproportionately affected by a new or amended national standard. The purpose of a subgroup analysis is to determine the extent of any such disproportional impacts. DOE evaluates impacts on particular subgroups of consumers by analyzing the LCC impacts and PBP for those particular consumers from alternative standard levels. 
For this direct final rule, DOE 
analyzed the impacts of the considered standard levels on low-income households and, for PC 11A, on small businesses. For low-income households, the analysis used a subset of the RECS 2020 sample composed of low-income households. DOE separately analyzed different groups in the low-income household sample using data from RECS on home ownership status and on who pays the electricity bill. Low-income homeowners are analyzed equivalently to how they are analyzed in the standard LCC analysis. Low-income renters who do not pay their electricity bill are assumed to not be impacted by any new or amended standards. In this case, the landlord purchases the appliance and pays its operating costs, so is effectively the consumer and the renter is not impacted. Low-income renters who do pay their electricity bill are assumed to incur no first cost. DOE made this assumption to acknowledge that the vast majority of low-income renters may not pay to have their refrigerator, refrigerator-freezer, or freezer replaced (that would be up to the landlord). 
DOE notes that RECS 2020 indicates 
that a small fraction of low-income households only have a single compact refrigerator and/or freezer. Because this is the only refrigeration product in the household, DOE assumed that the landlord typically supplies the product. Additionally, RECS 2020 indicates that a small fraction of low-income households have a refrigeration product that would be categorized into PC 5, PC 5BI, or PC 5A. As a result, DOE did not do a low-income subgroup analysis on PCs 5, 5BI, 5A, 11A, 17, and 18. 
For small businesses, DOE used the 
same sample from CBECS 2018 that was used in the standard LCC analysis but used discount rates specific to small businesses. DOE used the LCC and PBP model to estimate the impacts of the considered efficiency levels on these subgroups. 
Chapter 11 in the direct final rule TSD 
describes the consumer subgroup analysis. 
In response to the February 2023 
NOPR, AHAM commented that amended standards requiring more variable-speed compressors could lead to higher upfront costs, disproportionately impacting low- income consumers. (AHAM, No. 69 at p. 5) Whirlpool added that the proposed standards would raise the cost of entry- level models, which are the preferred models for low-income consumers. (Whirlpool, No. 70 at pp. 5–6) As noted previously, many low-income consumers are renters who are not 
expected to pay the incremental cost due to an amended standard. For low- income homeowners who are expected to bear that incremental cost, the analysis incorporates the higher incremental costs at each considered TSL. DOE notes that at the Recommended TSL (TSL 4), the estimated increase in installed cost relative to the baseline (EL 0) product across PCs 3, 7, and 9 is less than $20. Moreover, in the aggregate, DOE finds that low-income consumers have higher average LCC savings and lower payback periods relative to the general population (see the results in section

finds that, in the aggregate, only 8.6percent of impacted low-incomeconsumers would experience a net costat TSL 4, meaning 91.4 percent wouldsee no change or a net benefit.
AHAM also commented that DOE has 
not supported its split-incentive assumption for low-income renters (i.e., renters will reap benefits of more efficient products through lower utility bills while landlords have little to no incentive to purchase more efficient products) nor has DOE considered the impact of amended standards on low- income homeowners. (AHAM, No. 69 at p. 10) AHAM provided consumerresearch results indicating that cost isthe primary consideration forhouseholds when purchasing a newrefrigerator, low-income householdsthat make less than $25,000 per yearwould not be able to purchase a newrefrigerator, and 78 percent of suchhouseholds would not pay $100 extrafor a more efficient refrigerator thatsaved $50-$150 in utility bills over 10years. (AHAM, No. 69 at pp. 10–11)AHAM added that the proposedstandards in the February 2023 NOPRwill result in insignificant savings forconsumers, which do not amount to amaterial benefit, especially for low- income consumers. (AHAM, No. 69 at p.15) Whirlpool commented that DOE’sassumption that landlords will absorbincreased appliance costs and not passthem on to tenants is incorrect.(Whirlpool, No. 70 at p. 6)
The existence of a split-incentive 
across a substantial number of U.S. households, in which a tenant pays for the cost of electricity while the building owner furnishes appliances, has been identified through a number of studies of residential appliance and equipment use broadly. Building from early work including Jaffe and Stavins,
70 
Murtishaw and Sathaye71discussed the 
presence of landlord–tenant split incentives (i.e., the ‘‘principal-agent 
problem’’). While the study did not solely focus on the low-income households, they estimated that 33% of all residential refrigerator use is subject to the principal-agent problem, largely within rental housing. Spurlock and Fujita
72showed that 87% of low- income individuals who rented their 
homes were found to pay the electricity bill resulting from their energy use, such that they were likely subject to a scenario in which their landlord purchased the appliance, but they paid the operating costs. DOE notes that there continues to be a lack of data to corroborate the notion that landlords pass on some, or all, of increased appliance costs to tenants. Without representative data to suggest otherwise, DOE has continued to analyze low- income renters under the assumption that they pay no upfront costs under an amended standard in this direct final rule. DOE further notes, that AHAM is a party to the Joint Agreement and is supportive of the recommended standard adopted in this direct final rule. 
J. Manufacturer Impact Analysis1. Overview
DOE performed an MIA to estimate
the financial impacts of amended energy 
conservation standards on manufacturers of refrigerators, refrigerator-freezers, and freezers and to estimate the potential impacts of such standards on employment and manufacturing capacity. The MIA has both quantitative and qualitative aspects and includes analyses of projected industry cash flows, the INPV, investments in research and development (‘‘R&D’’) and manufacturing capital, and domestic manufacturing employment. Additionally, the MIA seeks to determine how amended energy conservation standards might affect manufacturing employment, capacity, and competition, as well as how standards contribute to overall regulatory burden. Finally, the MIA serves to identify any disproportionate impacts on manufacturer subgroups, including small business manufacturers. 
The quantitative part of the MIA 
primarily relies on the GRIM, an industry cash flow model with inputs specific to this rulemaking. The key GRIM inputs include data on the industry cost structure, unit production costs, product shipments, manufacturer markups, and investments in R&D and manufacturing capital required to produce compliant products. The key GRIM outputs are the INPV, which is the sum of industry annual cash flows over the analysis period, discounted using the industry weighted average cost of capital, and the impact to domestic manufacturing employment. The model uses standard accounting principles to estimate the impacts of more stringent energy conservation standards on a given industry by 
comparing changes in INPV and domestic manufacturing employment between a no-new-standards case and the various standards cases. To capture the uncertainty relating to manufacturer pricing strategies following amended standards, the GRIM estimates a range of possible impacts under different scenarios. 
The qualitative part of the MIA 
addresses manufacturer characteristics and market trends. Specifically, the MIA considers such factors as a potential standard’s impact on manufacturing capacity, competition within the industry, the cumulative impact of other DOE and non-DOE regulations, and impacts on manufacturer subgroups. The complete MIA is outlined in chapter 12 of the direct final rule TSD. 
DOE conducted the MIA for this 
rulemaking in three phases. In Phase 1 of the MIA, DOE prepared a profile of the refrigerators, refrigerator-freezers, and freezers manufacturing industry based on the market and technology assessment and publicly available information. This included a top-down analysis of refrigerators, refrigerator- freezers, and freezers manufacturers that DOE used to derive preliminary financial inputs for the GRIM (e.g., revenues; materials, labor, overhead, and depreciation expenses; selling, general, and administrative expenses (‘‘SG&A’’); and R&D expenses). DOE also used public sources of information to further calibrate its initial characterization of the refrigerators, refrigerator-freezers, and freezers manufacturing industry, including company filings of form 10–K from the SEC,
73corporate annual reports, the 
U.S. Census Bureau’s Annual Survey of Manufactures (‘‘ASM’’),
74and reports 
from Dun & Bradstreet.75 
In Phase 2 of the MIA, DOE prepared 
a framework industry cash flow analysis to quantify the potential impacts of amended energy conservation standards. The GRIM uses several factors to determine a series of annual cash flows starting with the announcement of the standard and extending over a 30-year period following the compliance date of the standard. These factors include annual expected revenues, costs of sales, SG&A 
VerDate Sep<11>2014 19:16 Jan 16, 2024 Jkt 262001 PO 00000 Frm 00041 Fmt 4701 Sfmt 4700 E:\FR\FM\17JAR2.SGM 17JAR2lotter on DSK11XQN23PROD with RULES23066 Federal Register / Vol. 89, No. 11 / Wednesday, January 17, 2024 / Rules and Regulations 
76For the no-new-standards case and all TSLs 
except for the Recommended TSL, the analysis 
period ranges from 2023–2056. For the Recommended TSL, the analysis period ranges from 2023–2058 for the product classes listed in Table I.1 and 2023–2059 for the product classes listed in Table I.2. 
77Id. and R&D expenses, taxes, and capital 
expenditures. In general, energy conservation standards can affect manufacturer cash flow in three distinct ways: (1) creating a need for increased investment, (2) raising production costs per unit, and (3) altering revenue due to higher per-unit prices and changes in sales volumes. 
In addition, during Phase 2, DOE 
developed interview guides to distribute to manufacturers of refrigerators, refrigerator-freezers, and freezers in order to develop other key GRIM inputs, including product and capital conversion costs, and to gather additional information on the anticipated effects of energy conservation standards on revenues, direct employment, capital assets, industry competitiveness, and subgroup impacts. 
In Phase 3 of the MIA, DOE 
conducted structured, detailed interviews with representative manufacturers. During these interviews, DOE discussed engineering, manufacturing, procurement, and financial topics to validate assumptions used in the GRIM and to identify key issues or concerns. As part of Phase 3, DOE also evaluated subgroups of manufacturers that may be disproportionately impacted by amended standards or that may not be accurately represented by the average cost assumptions used to develop the industry cash flow analysis. Such manufacturer subgroups may include small business manufacturers, low- volume manufacturers (‘‘LVMs’’), niche players, and/or manufacturers exhibiting a cost structure that largely differs from the industry average. DOE identified two subgroups for a separate impact analysis: small business manufacturers and domestic LVMs. The 
small business subgroup is discussed in chapter 12 of the direct final rule TSD. The domestic LVM subgroup is discussed in section V.B.2.d of this document and in chapter 12 of the direct final rule TSD. 
2. Government Regulatory Impact Model 
and Key Inputs 
DOE uses the GRIM to quantify the 
changes in cash flow due to amended standards that result in a higher or lower industry value. The GRIM uses a standard, annual discounted cash flow analysis that incorporates manufacturer costs, manufacturer markups, shipments, and industry financial information as inputs. The GRIM models change in costs, distribution of shipments, investments, and manufacturer margins that could result from an amended energy conservation standard. The GRIM spreadsheet uses 
the inputs to arrive at a series of annual cash flows, beginning in 2023 (the base year of the analysis) and continuing 30 years from the analyzed compliance year.
76DOE calculated INPVs by 
summing the stream of annual discounted cash flows during this 
period. For manufacturers of refrigerators, refrigerator-freezers, and freezers, DOE used a real discount rate of 9.1 percent, which was derived from industry financials and then modified according to feedback received during manufacturer interviews. 
The GRIM calculates cash flows using 
standard accounting principles and compares changes in INPV between the no-new-standards case and each standards case. The difference in INPV between the no-new-standards case and a standards case represents the financial impact of the amended energy conservation standard on manufacturers. As discussed previously, DOE developed critical GRIM inputs using a number of sources, including publicly available data, results of the engineering analysis, results of the shipments analysis, and information gathered from industry stakeholders during the course of manufacturer interviews. The GRIM results are presented in section V.B.2 of this document. Additional details about the GRIM, the discount rate, and other financial parameters can be found in chapter 12 of the direct final rule TSD. 
a. Manufacturer Production Costs 
Manufacturing more efficient 
products is typically more expensive 
than manufacturing baseline products due to the use of more complex components, which are typically more costly than baseline components. The changes in the MPCs of covered products can affect the revenues, gross margins, and cash flow of the industry. For a complete description of the MPCs, see chapter 5 of the direct final rule 
TSD. 
b. Shipments Projections 
The GRIM estimates manufacturer 
revenues based on total unit shipment 
projections and the distribution of those shipments by efficiency level. Changes in sales volumes and efficiency mix over time can significantly affect manufacturer finances. For this analysis, the GRIM uses the NIA’s annual shipment projections derived from the 
shipments analysis from the base year (2023) to 30 years from the analyzed compliance date.
77See chapter 9 of the 
direct final rule TSD for additional details. 
c. Product and Capital Conversion Costs 
Amended energy conservation 
standards could cause manufacturers to 
incur conversion costs to bring their production facilities and product designs into compliance. DOE evaluated the level of conversion-related expenditures that would be needed to comply with each considered efficiency level in each product class. For the MIA, DOE classified these conversion costs into two major groups: (1) product conversion costs; and (2) capital conversion costs. Product conversion costs are investments in research, development, testing, marketing, and other non-capitalized costs necessary to make product designs comply with amended energy conservation standards. Capital conversion costs are investments in property, plant, and equipment necessary to adapt or change existing production facilities such that new compliant product designs can be 
fabricated and assembled. 
Product Conversion Costs 
DOE based its estimates of the 
product conversion costs necessary to 
meet the varying efficiency levels on information from manufacturer interviews, the design paths analyzed in the engineering analysis, and market share and model count information. Generally, manufacturers preferred to meet amended standards with design options that were direct and relatively straight-forward component swaps, such as incrementally more efficiency compressors. However, at higher efficiency levels, manufacturers anticipated the need for platform redesigns. Efficiency levels that potentially necessitate significantly altered cabinet construction would require very large investments to update designs. Manufacturers noted that increasing foam thickness would require complete redesign of the cabinet, and potentially, the liner and shelving, should there be changes in interior volume. Additionally, extensive use of VIPs would require redesign of the cabinet to maximize the benefits of VIPs. 
Based on manufacturer feedback, DOE 
also estimated ‘‘re-flooring’’ costs associated with replacing obsolete display models in big-box stores (e.g., Lowe’s, Home Depot, Best Buy) due to

more stringent standards. Some 
manufacturers stated that with a new product release, big-box retailers discount outdated display models, and manufacturers share any losses associated with discounting the retail price. The estimated re-flooring costs for each efficiency level were incorporated into the product conversion cost estimates, as DOE modeled the re- flooring costs as a marketing expense. Manufacturer data was aggregated to protect confidential information. 
DOE interviewed manufacturers 
accounting for approximately 81 percent of domestic refrigerator, refrigerator- freezer, and freezer shipments. DOE scaled product conversion costs by model counts to account for the portion of companies that were not interviewed. In manufacturer interviews, DOE received feedback on the analyzed product classes. For non-represented product classes, for which there was less available data, DOE used model counts to scale the product conversion cost estimates for analyzed product classes. See chapter 10 of the direct final 
rule TSD for details on the mapping of analyzed product classes to non- represented product classes. See chapter 
12 of the direct final rule TSD for details on product conversion costs. 
Capital Conversion Costs 
DOE relied on information derived 
from manufacturer interviews and the 
engineering analysis to evaluate the level of capital conversion costs manufacturers would likely incur at the considered standard levels. During the interviews, manufacturers provided estimates and descriptions of the required tooling and plant changes that would be necessary to upgrade product lines to meet potential efficiency levels. Based on these inputs, DOE modeled incremental capital conversion costs for efficiency levels that could be reached 
with individual components swaps. However, based on feedback, DOE modeled major capital conversion costs when manufacturers would have to redesign their existing product platforms. DOE used information from manufacturer interviews to determine the cost of the manufacturing equipment and tooling necessary to implement complete redesigns. 
Increases in foam thickness require 
either reductions to interior volume or increases to exterior volume. Since most refrigerators, refrigerator-freezers, and freezers must fit within standard widths, increases in foam thickness could result in the loss of interior volume. The reduction of interior volume has significant consequences for manufacturing. In addition to redesigning the cabinet to increase the 
effectiveness of insulation, manufacturers must update all designs and tooling associated with the interior of the product. This could include the liner, shelving, drawers, and doors. Manufacturers would need to invest in significant new tooling to accommodate the changes in dimensions. 
To minimize reductions to interior 
volume, manufacturers may choose to adopt VIP technology. Extensive incorporation of VIPs into designs require significant upfront capital due to differences in the handling, storing, and manufacturing of VIPs as compared to typical polyurethane foams. These investments are incorporated into the conversion costs estimated in the MIA for efficiency levels that would likely necessitate VIP technology. VIPs are relatively fragile and must be protected from punctures and rough handling. If VIPs have leaks of any size, the panel will eventually lose much of its thermal 
insulative properties and structural strength. If already installed within a cabinet wall, a punctured VIP may significantly reduce the structural strength of the refrigerator, refrigerator- freezer, or freezer cabinet. As a result, VIPs require cautious handling during the manufacturing process. DOE did not receive detailed information about the percent of VIPs that are punctured during the manufacturing process. Manufacturers noted the need to allocate special warehouse space to ensure the VIPs are not jostled or roughly handled in the manufacturing environment. Furthermore, manufacturers anticipated the need for expansion of warehouse space to accommodate the storage of VIPs. VIPs require significantly more warehouse space than the polyurethane foams currently used in most refrigerators, refrigerator-freezers, and freezers. The application of VIPs can be challenging and requires significant investment in hard-tooling or robotic systems to ensure the panels are positioned properly within the cabinet or door. Manufacturers noted that producing cabinets with VIPs is much more labor- and time-intensive than producing cabinets with typical polyurethane foams. Particularly in high-volume factories, which can produce over a million refrigerator-freezers per year, the increase in production time associated in increased VIP usage would necessitate additional investment in manufacturing capacity to meet demand. The cost of extending production lines varies greatly by manufacturer, as it depends heavily on floor space availability in and around 
existing manufacturing plants. 
Higher volume manufacturers would 
generally have higher investments as they have more production lines and greater production capacity. For manufacturers of both PC 5 (‘‘refrigerator-freezer—automatic defrost with bottom-mounted freezer without an automatic ice maker’’) and PC 5A (‘‘refrigerator-freezer—automatic defrost with bottom-mounted freezer with through-the-door ice service’’), cabinet changes in one product class would likely necessitate improvements in the other product class as they often share the same architecture, tooling, and production lines. 
DOE estimated industry capital 
conversion costs by extrapolating the interviewed manufacturers’ capital conversion costs for each product class to account for the market share of 
companies that were not interviewed. DOE used the shipments analysis to scale the capital conversion cost estimates of the analyzed product class to account for the non-represented product class. See chapter 12 of the 
direct final rule TSD for additional details on capital conversion costs. 
Manufacturers may follow different 
design paths to reach the various efficiency levels analyzed. An individual manufacturer’s investments depend on a range of factors, including the company’s current product offerings and product platforms, existing production facilities and infrastructure, and make vs. buy decisions for components. DOE’s conversion cost methodology incorporated feedback from all manufacturers that took part in interviews and extrapolated industry values. While industry average values may not represent any single manufacturer, DOE’s model provides reasonable estimates of industry-level investments. 
DOE adjusted the conversion cost 
estimates developed in support of the February 2023 NOPR to 2022$ for this analysis. 
In general, DOE assumes all 
conversion-related investments occur between the year of publication of the direct final rule and the year by which manufacturers must comply with the new or amended standard. The conversion cost figures used in the GRIM can be found in section V.B.2 of this document. For additional information on the estimated capital and product conversion costs, see chapter 12 of the direct final rule TSD. 
d. Manufacturer Markup Scenarios 
MSPs include direct manufacturing 
production costs (i.e., labor, materials,

78The gross margin percentages of 21 percent and 
29 percent are based on manufacturer markups of 
1.26 and 1.40 percent, respectively. and overhead estimated in DOE’s MPCs) 
and all non-production costs (i.e., SG&A, R&D, and interest), along with profit. To calculate the MSPs in the GRIM, DOE applied manufacturer markups to the MPCs estimated in the engineering analysis for each product class and efficiency level. Modifying these manufacturer markups in the standards case yields different sets of impacts on manufacturers. For the MIA, DOE modeled two standards-case scenarios to represent uncertainty regarding the potential impacts on prices and profitability for manufacturers following the implementation of amended energy conservation standards: (1) a preservation-of-gross-margin-percentage scenario; and (2) a preservation-of- 
operating-profit scenario. These scenarios lead to different manufacturer markup values that, when applied to the MPCs, result in varying revenue and cash flow impacts. 
Under the preservation-of-gross- 
margin-percentage scenario, DOE applied a single uniform ‘‘gross margin percentage’’ across all efficiency levels, which assumes that manufacturers would be able to maintain the same amount of profit as a percentage of revenues at all efficiency levels within a product class. As manufacturer production costs increase with efficiency, this scenario implies that the per-unit dollar profit will increase. DOE assumed a gross margin percentage of 21 percent for all freestanding product classes and 29 percent for all built-in product classes.
78Manufacturers tend to 
believe it is optimistic to assume that they would be able to maintain the same gross margin percentage as their production costs increase, particularly for minimally efficient products. Therefore, this scenario represents a high bound of industry profitability under an amended energy conservation standard. 
In the preservation-of-operating-profit 
scenario, as the cost of production goes up under a standards case, manufacturers are generally required to reduce their manufacturer markups to a level that maintains base-case operating profit. DOE implemented this scenario in the GRIM by lowering the manufacturer markups at each TSL to yield approximately the same earnings before interest and taxes in the standards case as in the no-new- standards case in the year after the expected compliance date of the amended standards. The implicit assumption behind this scenario is that 
the industry can only maintain its operating profit in absolute dollars after the standard takes effect. 
A comparison of industry financial 
impacts under the two scenarios is presented in section V.B.2.a of this document. 
3. Discussion of MIA Comments 
For this direct final rule, DOE 
considered comments it had received 
regarding its MIA presented in the February 2023 NOPR. The approach used for this direct final rule is largely the same approach DOE had used for the February 2023 NOPR analysis. 
In response to the February 2023 
NOPR, AHAM stated that manufacturers may need to significantly redesign products in several classes to comply with the proposed DOE standards. In some high-volume product classes, AHAM asserted that there are no or very few shipments of products that meet the proposed standards. AHAM stated that this indicates that even when compliant models exist, they may not represent real-world shipments. AHAM commented that for other product classes, there is considerable variation in the availability of compliant models and shipments. AHAM added that in many instances, there are few compliant models and no reported shipments of compliant products, suggesting that substantial redesign efforts may be required across the market. (AHAM, No. 69 at pp. 2–3) 
DOE relied on multiple sources, 
including feedback from confidential manufacturer interviews and the design paths analyzed in the engineering 
analysis, to estimate the likely levels of redesign and investment required to meet each analyzed efficiency level. As discussed in section IV.J.2.c of this document, meeting higher efficiency levels may require product redesigns, particularly for efficiency levels that necessitate changes to the cabinet structure (i.e., changes to insulation 
such as increasing wall thickness or incorporating VIPs). Those costs are incorporated into the MIA. Regarding AHAM’s concerns about low shipments at higher efficiency levels, DOE incorporated data from stakeholders into the shipments analysis for this direct final rule analysis. DOE used confidential aggregate historical shipments data from 2015–2022 provided by AHAM to calibrate the total shipments for standard-size refrigerator- freezers, compact refrigerators, upright freezers, chest freezers, and built-in refrigerator-freezers. For this direct final rule, DOE also used the AHAM- provided estimates for the efficiency distributions based on shipments for standard-size refrigerator-freezers and compact freezers. See section IV.G of 
this document for additional information on the shipments analysis. 
In response to the February 2023 
NOPR, Whirlpool commented that a large decrease in INPV would stifle innovation as manufacturers would be forced to invest product development resources to meet the amended standards and potentially lay off U.S. production employees. (Whirlpool, No. 70 at p. 5) 
As discussed in section IV.J.2.c of this 
document, DOE’s analysis shows that as efficiency levels increase, more manufacturers would need to dedicate more financial, engineering, laboratory, and marketing resources to updating products to meet more stringent standards. DOE accounts for those investments in the MIA (see section 
V.B.2.a of this document). However, DOE disagrees with the assertion that redesigning products to improve energy efficiency is in opposition to product innovation. As indicated by manufacturers’ participation in the Environmental Protection Agency’s (EPA) voluntary ENERGY STAR program and the estimated shipments that meet ENERGY STAR levels, manufacturers and consumers consider energy efficiency a product attribute. Of the 63 refrigerator, refrigerator-freezer, and freezer original equipment manufacturers (OEMs) identified, approximately 46 OEMs manufacture models that meet ENERGY STAR levels and certify those models with the ENERGY STAR program. Approximately 22 percent of refrigerator, refrigerator-freezer, and freezer shipments already meet ENERGY STAR levels. Regarding the potential for a reduction in direct employment as a result of amended standards, DOE provides a range of potential quantitative impacts to direct employment and a discussion of the potential qualitative impacts to direct employment in section V.B.2.b of this document. Most major manufacturers with U.S. production facilities currently produce a portion of their products outside of the United States (e.g., Mexico). Adopting an amended standard that necessitates large increases in labor content or large expenditures to re-tool facilities could cause manufacturers to reevaluate domestic production siting options. See section V.B.2.b of this document for additional details on potential impacts to direct employment. DOE further notes, that Whirlpool is a party to the Joint Agreement and is supportive of the 
VerDate Sep<11>2014 19:16 Jan 16, 2024 Jkt 262001 PO 00000 Frm 00044 Fmt 4701 Sfmt 4700 E:\FR\FM\17JAR2.SGM 17JAR2lotter on DSK11XQN23PROD with RULES23069 Federal Register / Vol. 89, No. 11 / Wednesday, January 17, 2024 / Rules and Regulations 
recommended standard adopted in this 
direct final rule. 
Whirlpool commented that adoption 
of the proposed standard levels could make it difficult for multi-brand companies like Whirlpool to differentiate their products and product lines from other manufacturers as models become more technologically complex and costly. Whirlpool added that this could lead to the elimination of certain product segments and result in lost energy savings as consumers switch to more energy-intensive product types. (Whirlpool, No. 70 at pp. 7–8) 
DOE uses the GRIM, as described in 
section IV.J.2 of this document, to determine the quantitative impacts on the refrigerators, refrigerator-freezer, and freezer industry as a whole. DOE recognizes that the industry impacts do not apply evenly across manufacturers. Many manufacturers would need to update certain product designs to meet amended standard levels. However, DOE expects that manufacturers would still be able to differentiate their products and product lines by various factors (e.g., price, technologies, 
consumer features, energy efficiency). At the adopted level, all analyzed product classes will be required to meet efficiency levels below max-tech levels. Thus, DOE does not expect manufacturers would need to implement all analyzed design options across their product portfolio to meet the adopted levels. Furthermore, in this direct final rule, DOE is adopting the Recommended TSL, which would require lower efficiency levels for high- volume product classes such as PC 5A and PC 7, as compared to the levels proposed in the February 2023 NOPR. Additionally, AHAM, a trade organization representing the interests of their members, including Whirlpool and other refrigerator, refrigerator- freezer, and freezer OEMs, is a signatory of the Joint Agreement. As discussed in section IV.A.1 of this document, DOE is adopting energy allowances for special door and multi-door designs for some product classes. Therefore, DOE expects that these types of features and others will remain prevalent in the market and could offer means for product differentiation. See section IV.A.1 of 
this document for additional 
information on the energy use allowances. 
The California Investor-Owned 
Utilities (‘‘CA IOUs’’) noted the differences between PC 7 and PC 5A in DOE’s proposed energy efficiency standards for refrigerators, refrigerator- freezers, and freezers. The CA IOUs commented that the main difference between the two classes is the cost of moving to the VIP side walls and doors at max-tech EL, with PC 7 having a substantially higher order of magnitude for capital conversion costs compared to PC 5A. The CA IOUs recommended revising the proposal to consider EL 5 for PC 7 instead of EL 4. The CA IOUs requested that DOE elaborate on the reason for the differences in cost. (CA IOUs, No. 72 at p. 5) 
DOE relied on manufacturer feedback, 
among other sources, to derive the estimated product and capital conversion costs at each efficiency level for each directly analyzed product class. There are many reasons why the incremental industry conversion costs at each efficiency level could vary between product classes. These reasons include but are not limited to differences in analyzed design options, production volume, the number of models that would require redesign, the number of OEMs engaged in manufacturing each product class, the age of the product families and/or production equipment, and location of the production facilities. For PC 7, manufacturers could include less VIPs to meet the required efficiency level at EL 4 compared to EL 5. At EL 4, 75 percent of the maximum area could incorporate VIPs whereas EL 5 could incorporate VIPs for the maximum area on sidewalls and doors. As discussed in section IV.J.2.c of this document, incorporation of VIPs into designs requires significant upfront capital due to differences in the handling, storing, and manufacturing of VIPs as compared to typical polyurethane foams. DOE estimates the difference in capital conversion costs to be $117.9 million between EL 4 and EL 5. For product conversion costs, extensive use of VIPs would require redesign of the cabinet to maximize the benefits of VIPs. DOE estimated the difference to be $18.8 million between EL 4 and EL 5, which is attributed to design efforts required to meet 75 percent of maximum area of VIPs at EL 4 and the maximum area of VIPs at EL 5. Although manufacturers may incorporate some VIPs (on side walls and doors) for EL 2 for PC 5A, EL 2 may be achieved by component swaps rather than product redesign based on information gathered during manufacturer interviews. AHAM commented the cumulative regulatory burden is significant for home appliance manufacturers when redesigning products and product lines for consumer clothes dryers, residential clothes washers, conventional cooking products, refrigeration products, miscellaneous refrigeration products, and room air conditioners. (AHAM, No. 69 at p. 20) AHAM asserted that engineers will therefore need to spend all their time redesigning products to meet more stringent energy efficiency standards, pulling resources from other development efforts and business priorities. AHAM suggested that DOE could reduce cumulative regulatory burden by spacing out the timing of final rules, allowing more lead time by delaying the publication of final rules in the Federal Register after they have 
been issued, and reducing the stringency of standards such that fewer products would require redesign. (Id. At 
p. 21) AHAM urged DOE to fully review the cumulative impacts its rules will have on manufacturers (as well as consumers). AHAM suggested that this review should include examining the potential impact on the economy and inflation as a result of reducing INPV so significantly. (Id. At p. 22) 
DOE analyzes cumulative regulatory 
burden in accordance with section 13(g) of the Process Rule. DOE details the rulemakings and expected conversion expenses of Federal energy conservation standards that could impact refrigerator, refrigerator-freezer, and freezer OEMs that take effect approximately 3 years before the 2029 compliance date and 3 years after the 2030 compliance date in section V.B.2.e of this document. As shown in Table V.29 in section V.B.2.e of this document, DOE considers the potential cumulative regulatory burden from other DOE energy conservation standards rulemakings for consumer clothes dryers, residential clothes washers, conventional cooking products, refrigeration products, miscellaneous refrigeration products, and room air conditioners in this direct final rule analysis. Regarding AHAM’s suggestion about spacing out the timing of final rules for home appliance rulemakings, DOE has statutory requirements under EPCA on the timing of rulemakings. For refrigerators, refrigerator-freezers, and freezers, consumer conventional cooking products, residential clothes washers, consumer clothes dryers, room air conditioners, and dishwashers, amended standards apply to covered products manufactured 3 years after the date on which any new or amended standard is published. (42 U.S.C. 6295(m)(4)(A)(i)) For miscellaneous refrigeration products, amended standards apply 5 years after the date on which any new or amended standard is published. (42 U.S.C. 6295(l)(2)) However, the multi-product Joint Agreement recommends alternative compliance dates. As discussed in section of this document, the Joint

80For further information, see the Assumptions to 
AEO2023 report that sets forth the major 
assumptions used to generate the projections in the Agreement recommendations are in 
accordance with the statutory requirements of 42 U.S.C. 6295(p)(4) for the issuance of a direct final rule. Therefore, as compared to the EPCA- required lead time, manufacturers will have additional time to meet amended standards for refrigerators, refrigerator- freezers, and freezers in this direct final rule. 
Regarding examining the cumulative 
impacts of energy conservation standards rulemakings on manufacturers and consumers, DOE must follow specific statutory criteria for prescribing new or amended standards for covered products, including refrigerators, refrigerator- freezers, and freezers. An amended standard must be designed to achieve the maximum improvement in energy efficiency that is determined to be technologically feasible and economically justified. (42 U.S.C. 6295(o)(2)(A) and 42 U.S.C. 6295(o)(3)(B)) In its assessment of whether standards are economically justified, DOE considers the impact of the standard on manufacturers and consumers. DOE analyzes the impacts to manufacturers in accordance with section 13 of the Process Rule and the impacts to consumers in accordance with section 14 of the Process Rule. Although DOE does not analyze the cumulative burden on consumers, section V.B.1.a of this document discusses the economic impact of amended standards on individual consumers, which is the main impact consumers will face with a final amended energy conservation standard. 
AHAM stated that it cannot comment 
on the accuracy of DOE’s approach for including how manufacturers might or might not recover potential investments (i.e., the accuracy of DOE’s 
manufacturer markup scenarios) but that AHAM supports DOE’s intent in the microwave ovens supplemental notice of proposed rulemaking (‘‘SNOPR’’) (‘‘August 2022 SNOPR’’) energy conservation standards rulemaking to include those costs and investments in the actual costs of products and retail prices. 87 FR 52282. AHAM urged DOE to apply the same conceptual approach used in the August 2022 SNOPR in this refrigerator/freezer and all future 
rulemakings (i.e., to analyze a 
conversion-cost-recovery manufacturer markup scenario). (AHAM, No. 69 at p. 18) 
As discussed in section IV.J.2.d of this 
document, DOE modeled two standards- case manufacturer markup scenarios to represent the uncertainty regarding the potential impacts on prices and profitability for manufacturers following the implementation of amended energy 
conservation standards. For the February 2023 NOPR, DOE applied the preservation-of-gross-margin-percentage scenario to reflect an upper bound of industry profitability and a preservation-of-operating-profit scenario to reflect a lower bound of industry profitability under amended standards. DOE used these scenarios to reflect the range of realistic profitability impacts under more stringent standards. Manufacturing more efficient refrigerators, refrigerator-freezers, and freezers is generally more expensive than manufacturing baseline refrigerators, refrigerator-freezers, and freezers, as reflected by the MPCs estimated in the engineering analysis. Under the preservation-of-gross-margin scenario for refrigerators, refrigerator- freezers, and freezers, incremental increases in MPCs at higher efficiency levels result in an increase in per-unit dollar profit per unit sold. In interviews, multiple manufacturers asserted that they would likely need to reduce manufacturer markups under more stringent standards to remain competitive in the marketplace. Therefore, the preservation of gross- margin-scenario represents the upper bound of industry profitability under amended standards. Applying the approach used in the microwave ovens rulemaking (i.e., a conversion-cost- 
recovery scenario) would result in manufacturers increasing manufacturer markups under amended standards. Based on information gathered during confidential interviews in support of the February 2023 NOPR and a review of financial statements of companies engaged in manufacturing refrigerators, refrigerator-freezers, and freezers, DOE does not expect that the refrigerators, refrigerator-freezers, and freezers industry would increase manufacturer markups under an amended standard. Furthermore, in response to the February 2023 NOPR, DOE did not receive any public or confidential data indicating that industry would increase manufacturer markups in response to more stringent standards. Therefore, DOE maintained the two manufacturer markup scenarios from the February 2023 NOPR for this direct final rule analysis. 
K. Emissions Analysis 
The emissions analysis consists of 
two components. The first component 
estimates the effect of potential energy 
conservation standards on power sector and site (where applicable) combustion emissions of CO
2, NO X, SO 2, and Hg. 
The second component estimates the impacts of potential standards on emissions of two additional greenhouse 
gases, CH
4and N 2O, as well as the 
reductions in emissions of other gases due to ‘‘upstream’’ activities in the fuel production chain. These upstream activities comprise extraction, processing, and transporting fuels to the site of combustion. 
The analysis of electric power sector 
emissions of CO
2, NO X, SO 2, and Hg 
uses emissions intended to represent the marginal impacts of the change in electricity consumption associated with amended or new standards. The methodology is based on results published for the AEO, including a set 
of side cases that implement a variety of efficiency-related policies. The methodology is described in appendix 13A in the direct final rule TSD. The analysis presented in this notice uses projections from AEO2023. Power sector 
emissions of CH
4and N 2O from fuel 
combustion are estimated using Emission Factors for Greenhouse Gas Inventories published by the Environmental Protection Agency (EPA).
79 
FFC upstream emissions, which 
include emissions from fuel combustion during extraction, processing, and transportation of fuels, and ‘‘fugitive’’ emissions (direct leakage to the atmosphere) of CH
4and CO 2, are 
estimated based on the methodology described in chapter 15 of the direct final rule TSD. 
The emissions intensity factors are 
expressed in terms of physical units per megawatt-hour (‘‘MWh’’) or million 
British thermal units (‘‘MMBtu’’) of site energy savings. For power sector emissions, specific emissions intensity factors are calculated by sector and end use. Total emissions reductions are estimated using the energy savings calculated in the national impact analysis. 
1. Air Quality Regulations Incorporated 
in DOE’s Analysis 
DOE’s no-new-standards case for the 
electric power sector reflects the AEO, which incorporates the projected impacts of existing air quality regulations on emissions. AEO2023 generally represents current legislation and environmental regulations, including recent government actions, that were in place at the time of preparation of AEO2023, including the 
emissions control programs discussed in the following paragraphs.

Annual Energy Outlook. Available at www.eia.gov/ 
outlooks/aeo/assumptions/ (last accessed July 13, 
2023). 
81CSAPR requires states to address annual 
emissions of SO 2and NO X, precursors to the 
formation of fine particulate matter (‘‘PM 2.5’’) 
pollution, in order to address the interstate transport of pollution with respect to the 1997 and 2006 PM
2.5National Ambient Air Quality Standards 
(‘‘NAAQS’’). CSAPR also requires certain states to 
address the ozone season (May-September) emissions of NO
X, a precursor to the formation of 
ozone pollution, in order to address the interstate transport of ozone pollution with respect to the 1997 ozone NAAQS. 76 FR 48208 (Aug. 8, 2011). EPA subsequently issued a supplemental rule that included an additional five states in the CSAPR ozone season program; 76 FR 80760 (Dec. 27, 2011) (Supplemental Rule), and EPA issued the CSAPR Update for the 2008 ozone NAAQS. 81 FR 74504 (Oct. 26, 2016). SO 2emissions from affected electric 
generating units (‘‘EGUs’’) are subject to 
nationwide and regional emissions cap- and-trade programs. Title IV of the Clean Air Act sets an annual emissions cap on SO
2for affected EGUs in the 48 
contiguous States and the District of Columbia (‘‘DC’’). (42 U.S.C. 7651 et seq.) SO
2emissions from numerous 
States in the eastern half of the United States are also limited under the Cross- State Air Pollution Rule (‘‘CSAPR’’). 76 FR 48208 (Aug. 8, 2011). CSAPR requires these States to reduce certain emissions, including annual SO
2 
emissions, and went into effect as of January 1, 2015.
81AEO2023 
incorporates implementation of CSAPR, including the update to the CSAPR ozone season program emission budgets and target dates issued in 2016. 81 FR 74504 (Oct. 26, 2016). Compliance with CSAPR is flexible among EGUs and is enforced through the use of tradable emissions allowances. Under existing EPA regulations, for states subject to SO
2emissions limits under CSAPR, any 
excess SO 2emissions allowances 
resulting from the lower electricity demand caused by the adoption of an efficiency standard could be used to permit offsetting increases in SO
2 
emissions by another regulated EGU. 
However, beginning in 2016, SO 2 
emissions began to fall as a result of the Mercury and Air Toxics Standards (‘‘MATS’’) for power plants. 77 FR 9304 (Feb. 16, 2012). The direct final rule establishes power plant emission standards for mercury, acid gases, and non-mercury metallic toxic pollutants. In order to continue operating, coal plants must have either flue gas desulfurization or dry sorbent injection systems installed. Both technologies, which are used to reduce acid gas emissions, also reduce SO
2emissions. 
Because of the emissions reductions under the MATS, it is unlikely that excess SO
2emissions allowances 
resulting from the lower electricity demand would be needed or used to 
permit offsetting increases in SO 2 
emissions by another regulated EGU. Therefore, energy conservation standards that decrease electricity generation will generally reduce SO
2 
emissions. DOE estimated SO 2 
emissions reduction using emissions factors based on AEO2023. 
CSAPR also established limits on NO
X 
emissions for numerous States in the eastern half of the United States. Energy conservation standards would have little effect on NO
Xemissions in those 
States covered by CSAPR emissions limits if excess NO
Xemissions 
allowances resulting from the lower electricity demand could be used to permit offsetting increases in NO
X 
emissions from other EGUs. In such case, NO
Xemissions would remain near 
the limit even if electricity generation goes down. Depending on the configuration of the power sector in the different regions and the need for allowances, however, NO
Xemissions 
might not remain at the limit in the case of lower electricity demand. That would mean that standards might reduce NO
X 
emissions in covered States. Despite this possibility, DOE has chosen to be conservative in its analysis and has maintained the assumption that standards will not reduce NO
X 
emissions in States covered by CSAPR. Standards would be expected to reduce NO
Xemissions in the States not covered 
by CSAPR. DOE used AEO2023 data to 
derive NO Xemissions factors for the 
group of States not covered by CSAPR. 
The MATS limit mercury emissions 
from power plants, but they do not include emissions caps and, as such, DOE’s energy conservation standards would be expected to slightly reduce Hg emissions. DOE estimated mercury emissions reduction using emissions factors based on AEO2023, which 
incorporates the MATS. 
L. Monetizing Emissions Impacts 
As part of the development of this 
direct final rule, for the purpose of 
complying with the requirements of Executive Order 12866, DOE considered the estimated monetary benefits from the reduced emissions of CO
2, CH 4, 
N2O, NO X, and SO 2that are expected to 
result from each of the TSLs considered. In order to make this calculation analogous to the calculation of the NPV of consumer benefit, DOE considered the reduced emissions expected to result over the lifetime of products shipped in the projection period for each TSL. This section summarizes the basis for the values used for monetizing the emissions benefits and presents the values considered in this direct final 
rule. 
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 IWG. 
1. Monetization of Greenhouse Gas 
Emissions 
DOE estimates the monetized benefits 
of the reductions in emissions of CO
2, 
CH 4, and N 2O by using a measure of the 
SC of each pollutant (e.g., SC–CO 2). 
These estimates represent the monetary value of the net harm to society associated with a marginal increase in emissions of these pollutants in a given year, or the benefit of avoiding that increase. These estimates are intended to include (but are not limited to) climate-change-related changes in net agricultural productivity, human health, property damages from increased flood risk, disruption of energy systems, risk of conflict, environmental migration, and the value of ecosystem services. 
For this direct final rule, DOE 
considered comments it had received regarding its approach for monetizing greenhouse gas emissions in the 
February 2023 NOPR. The approach used for this direct final rule is largely the same approach DOE had used for the February 2023 NOPR analysis. 
The attorneys general (AGs) of TN, 
AL, et al. commented that DOE’s 
misguided use of the SC–GHG estimates is a significant problem with the proposed standards. The AGs of TN, AL, et al. attached as evidence their comment letter in response to DOE’s proposed standards for consumer conventional cooking products, in which they expressed detailed concerns about the IWG estimates. The AGs of TN, AL, et al. noted that the reversal of the preliminary injunction that a coalition of States received in Louisiana v. Biden, 585 F. Supp. 3d 840 (W.D. La. 
2022) does not change the criticisms in the aforementioned comment letter. (The AGs of TN, AL, et al., No. 68 at pp. 1–2) 
The IWG’s SC–GHG estimates were 
developed over many years, using transparent process, peer-reviewed methodologies, the best science available at the time of that process, and with input from the public. A number of criticisms raised in the comment letter attached by the AGs of TN, AL, et al. were addressed by the IWG in its 
February 2021 SC–GHG TSD, and previous parts of this section summarized the IWG’s conclusions on

discount rates cited by the Competitive Enterprise Institute (‘‘CEI’’). The IWG’s 2016 TSD
82and the 2017 National 
Academies report provide detailed discussions of the ways in which the modeling underlying the development of the SC–GHG estimates addressed quantified sources of uncertainty. In the February 2021 SC–GHG TSD, the IWG stated that the models used to produce the interim estimates do not include all of the important physical, ecological, and economic impacts of climate change recognized in the climate change literature. For these same impacts, the science underlying their ‘‘damage functions’’ lags behind the most recent research. In the judgment of the IWG, these and other limitations suggest that the range of four interim SC–GHG estimates presented in the TSD likely underestimate societal damages from GHG emissions. The IWG is in the process of assessing how best to incorporate the latest peer-reviewed science and the recommendations of the National Academies to develop an updated set of SC–GHG estimates. 
AHAM objected to DOE using the 
social cost of carbon and other monetization of emissions reductions benefits in its analysis of the factors EPCA requires DOE to balance in determining the appropriate standard. AHAM stated that while it may be acceptable for DOE to continue its current practice of examining the SCC and monetization of other emissions reductions benefits as informational so long as the underlying interagency 
analysis is transparent and vigorous, the monetization analysis should not impact the TSLs DOE selects as a new or amended standard. (AHAM, No. 69 at pp. 22–23) The AGs of TN, AL, et al. stated that even if it is important to take into account emissions reductions when considering the need for national energy conservation (as DOE has claimed), the IWG estimates are unlawful and poor methods for doing so. The AGs of TN, AL, et al. concluded that the IWG’s SC– 
GHG estimates are fundamentally flawed and are an unreliable metric on which to base administrative action. (The AGs of TN, AL, et al., No. 68 at pp. 1–2) 
As stated in section III.F.1.f of this 
document, DOE accounts for the environmental and public health benefits associated with the more efficient use of energy, including those 
connected to global climate change, as they are important to take into account when considering the need for national energy conservation. (See 42 U.S.C. 
6295(o)(2)(B)(i)(IV)) In addition, Executive Order 13563, which was re- affirmed on January 21, 2021, stated that each agency must, among other things: ‘‘select, in choosing among alternative regulatory approaches, those approaches that maximize net benefits (including potential economic, environmental, public health and safety, and other advantages; distributive impacts; and equity).’’ For these reasons, DOE includes the monetized value of emissions reductions in its evaluation of potential standard levels. While the benefits associated with reduction of GHG emissions inform DOE’s evaluation of potential standards, the action of proposing or adopting specific standards is not ‘‘based on’’ the SC– GHG values, as DOE would reach the same conclusion regarding the economic justification of standards presented in this direct final rule without considering the social cost of greenhouse gases. 
DOE exercises its own judgment in 
presenting monetized climate benefits as recommended by applicable Executive orders, and DOE would reach the same conclusion presented in this proposed rulemaking in the absence of the social cost of greenhouse gases. That is, the social costs of greenhouse gases, whether measured using the February 2021 interim estimates presented by the Interagency Working Group on the Social Cost of Greenhouse Gases or by another means, did not affect the rule ultimately proposed by DOE. 
DOE estimated the global social 
benefits of CO
2, CH 4, and N 2O 
reductions using SC–GHG values that were based on the interim values 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 IWG. The SC–GHG is the monetary value of the net harm to society associated with a marginal increase in emissions in a given year, or the benefit of avoiding that increase. In principle, the SC–GHG includes the value of all climate change impacts, including (but not limited to) changes in net agricultural productivity, human health effects, property damage from increased flood risk and natural disasters, disruption of energy systems, risk of conflict, environmental migration, and the value of ecosystem services. The SC–GHG therefore, reflects 
the societal value of reducing emissions of the gas in question by one metric ton. The SC–GHG is the theoretically appropriate value to use in conducting benefit-cost analyses of policies that affect CO
2, N2O, and CH 4emissions. As 
a member of the IWG involved in the development of the February 2021 SC– GHG TSD, DOE agrees that the interim SC–GHG estimates represent the most appropriate estimate of the SC–GHG until revised estimates have been developed reflecting the latest, peer- reviewed science. 
The SC–GHG estimates presented 
here were developed over many years, using transparent process, peer- reviewed methodologies, the best science available at the time of that process, and with input from the public. Specifically, in 2009, the IWG, that included the DOE and other executive branch agencies and offices was established to ensure that agencies were using the best available science and to promote consistency in the social cost of carbon (SC–CO
2) values used across 
agencies. The IWG published SC–CO 2 
estimates in 2010 that were developed from an ensemble of three widely cited integrated assessment models (IAMs) that estimate global climate damages using highly aggregated representations of climate processes and the global economy combined into a single modeling framework. The three IAMs were run using a common set of input assumptions in each model for future population, economic, and CO
2 
emissions growth, as well as equilibrium climate sensitivity—a measure of the globally averaged temperature response to increased atmospheric CO
2concentrations. These 
estimates were updated in 2013 based on new versions of each IAM. In August 2016 the IWG published estimates of the social cost of methane (SC–CH
4) and 
nitrous oxide (SC–N 2O) using 
methodologies that are consistent with the methodology underlying the SC– CO
2estimates. The modeling approach 
that extends the IWG SC–CO 2 
methodology to non-CO 2GHGs has 
undergone multiple stages of peer review. The SC–CH
4and SC–N 2O 
estimates were developed by Marten et al.
83and underwent a standard double- 
blind peer review process prior to journal publication. In 2015, as part of the response to public comments received to a 2013 solicitation for comments on the SC–CO
2estimates, the 
IWG announced a National Academies of Sciences, Engineering, and Medicine

advice on how to approach future 
updates to ensure that the estimates continue to reflect the best available science and methodologies. In January 2017, the National Academies released their final report, ‘‘Valuing Climate Damages: Updating Estimation of the Social Cost of Carbon Dioxide,’’ and recommended specific criteria for future updates to the SC–CO
2estimates, a 
modeling framework to satisfy the specified criteria, and both near-term updates and longer-term research needs pertaining to various components of the estimation process (National Academies, 2017).
84Shortly thereafter, 
in March 2017, President Trump issued Executive Order 13783, which disbanded the IWG, withdrew the previous TSDs, and directed agencies to ensure SC–CO
2estimates used in 
regulatory analyses are consistent with the guidance contained in OMB’s Circular A–4, ‘‘including with respect to the consideration of domestic versus international impacts and the consideration of appropriate discount rates’’ (E.O. 13783, section 5I). Benefit- cost analyses following E.O. 13783 used SC–GHG estimates that attempted to focus on the U.S.-specific share of climate change damages as estimated by the models and were calculated using two discount rates recommended by Circular A–4, 3 percent and 7 percent. All other methodological decisions and model versions used in SC–GHG calculations remained the same as those used by the IWG in 2010 and 2013, respectively. 
On January 20, 2021, President Biden 
issued Executive Order 13990, which re- established the IWG and directed it to ensure that the U.S. Government’s estimates of the social cost of carbon and other greenhouse gases reflect the best available science and the recommendations of the National Academies (2017). The IWG was tasked with first reviewing the SC–GHG estimates currently used in Federal analyses and publishing interim estimates within 30 days of the E.O. that reflect the full impact of GHG emissions, including by taking global damages into account. The interim SC– GHG estimates published in February 2021 are used here to estimate the climate benefits for this proposed rulemaking. The E.O. instructs the IWG to undertake a fuller update of the SC– GHG estimates by January 2022 that takes into consideration the advice of the National Academies (2017) and other recent scientific literature. The February 2021 SC–GHG TSD provides a complete discussion of the IWG’s initial review conducted under E.O.13990. In particular, the IWG found that the SC– GHG estimates used under E.O. 13783 fail to reflect the full impact of GHG emissions in multiple ways. 
First, the IWG found that the SC–GHG 
estimates used under E.O. 13783 fail to fully capture many climate impacts that affect the welfare of U.S. citizens and residents, and those impacts are better reflected by global measures of the SC– GHG. Examples of omitted effects from the E.O. 13783 estimates include direct effects on U.S. citizens, assets, and investments located abroad, supply chains, U.S. military assets and interests abroad, and tourism, and spillover pathways such as economic and political destabilization and global migration that can lead to adverse impacts on U.S. national security, public health, and humanitarian concerns. In addition, assessing the benefits of U.S. GHG mitigation activities requires consideration of how those actions may affect mitigation activities by other countries, as those international mitigation actions will provide a benefit to U.S. citizens and residents by mitigating climate impacts that affect U.S. citizens and residents. A wide range of scientific and economic experts have emphasized the issue of reciprocity as support for considering global damages of GHG emissions. If the United States does not consider impacts on other countries, it is difficult to convince other countries to consider the impacts of their emissions on the United States. The only way to achieve an efficient allocation of resources for emissions reduction on a global basis— and so benefit the U.S. and its citizens— is for all countries to base their policies on global estimates of damages. As a member of the IWG involved in the development of the February 2021 SC– GHG TSD, DOE agrees with this assessment and, therefore, in this proposed rule DOE centers attention on a global measure of SC–GHG. This approach is the same as that taken in DOE regulatory analyses from 2012 through 2016. A robust estimate of climate damages that accrue only to U.S. citizens and residents does not currently exist in the literature. As explained in the February 2021 SC–GHG TSD, existing estimates are both incomplete and an underestimate of total damages that accrue to the citizens and residents of the U.S. because they do not fully capture the regional interactions and spillovers discussed above, nor do they 
include all of the important physical, ecological, and economic impacts of climate change recognized in the climate change literature. As noted in the February 2021 SC–GHG TSD, the IWG will continue to review developments in the literature, including more robust methodologies for estimating a U.S.-specific SC–GHG value, and explore ways to better inform the public of the full range of carbon impacts. As a member of the IWG, DOE will continue to follow developments in the literature pertaining to this issue. 
Second, the IWG found that the use of 
the social rate of return on capital (7 percent under current OMB Circular A– 4 guidance) to discount the future benefits of reducing GHG emissions inappropriately underestimates the 
impacts of climate change for the purposes of estimating the SC–GHG. Consistent with the findings of the National Academies (2017) and the economic literature, the IWG continued to conclude that the consumption rate of interest is the theoretically appropriate discount rate in an intergenerational context,
85and recommended that 
discount rate uncertainty and relevant aspects of intergenerational ethical considerations be accounted for in selecting future discount rates. 
Furthermore, the damage estimates 
developed for use in the SC–GHG are estimated in consumption-equivalent terms, and so an application of OMB Circular A–4’s guidance for regulatory analysis would then use the consumption discount rate to calculate

Document: Social Cost of Carbon, Methane, and Nitrous Oxide Interim Estimates under Executive Order 13990. February. United States Government. Available at www.whitehouse.gov/briefing-room/ blog/2021/02/26/a-return-to-science-evidence-

pollution/ (last accessed July 12, 2023). the SC–GHG. DOE agrees with this 
assessment and will continue to follow developments in the literature pertaining to this issue. DOE also notes that while OMB Circular A–4, as published in 2003, recommends using 3-percent and 7-percent discount ratesas ‘‘default’’ values, Circular A–4 alsoreminds agencies that ‘‘differentregulations may call for differentemphases in the analysis, depending onthe nature and complexity of theregulatory issues and the sensitivity ofthe benefit and cost estimates to the keyassumptions.’’ On discounting, CircularA–4 recognizes that ‘‘special ethicalconsiderations arise when comparingbenefits and costs across generations,’’and Circular A–4 acknowledges thatanalyses may appropriately ‘‘discountfuture costs and consumption benefits. . . at a lower rate than forintragenerational analysis.’’ In the 2015‘‘Response to Comments on the SocialCost of Carbon for Regulatory ImpactAnalysis,’’ OMB, DOE, and the otherIWG members recognized that ‘‘CircularA–4 is a living document’’ and ‘‘the useof 7 percent is not consideredappropriate for intergenerationaldiscounting. There is wide support forthis view in the academic literature, andit is recognized in Circular A–4 itself.’’Thus, DOE concludes that a 7-percentdiscount rate is not appropriate to applyto value the social cost of greenhousegases in the analysis presented in thisanalysis.
To calculate the present and 
annualized values of climate benefits, DOE uses the same discount rate as the rate used to discount the value of damages from future GHG emissions, for internal consistency. That approach to discounting follows the same approach that the February 2021 SC–GHG TSD recommends ‘‘to ensure internal consistency—i.e., future damages from 
climate change using the SC–GHG at 2.5 percent should be discounted to the base year of the analysis using the same 2.5-percent rate.’’ DOE has also consulted the National Academies’ 2017 recommendations on how SC–GHG estimates can ‘‘be combined in RIAs [regulatory impact analyses] with other cost and benefits estimates that may use different discount rates.’’ The National Academies reviewed several options, including ‘‘presenting all discount rate combinations of other costs and benefits with [SC–GHG] estimates.’’ 
As a member of the IWG involved in 
the development of the February 2021 SC–GHG TSD, DOE agrees with the above assessment and will continue to 
follow developments in the literature pertaining to this issue. While the IWG works to assess how best to incorporate the latest, peer-reviewed science to develop an updated set of SC–GHG estimates, it set the interim estimates to be the most recent estimates developed by the IWG prior to the group being disbanded in 2017. The estimates rely on the same models and harmonized inputs and are calculated using a range of discount rates. As explained in the February 2021 SC–GHG TSD, the IWG has recommended that agencies revert to the same set of four values drawn from the SC–GHG distributions based on three discount rates as were used in regulatory analyses between 2010 and 2016 and were subject to public comment. For each discount rate, the IWG combined the distributions across models and socioeconomic emissions scenarios (applying equal weight to each) and then selected a set of four values recommended for use in benefit- cost analyses: an average value resulting from the model runs for each of three discount rates (2.5 percent, 3 percent, and 5 percent), plus a fourth value, selected as the 95th percentile of estimates based on a 3-percent discount rate. The fourth value was included to provide information on potentially higher-than-expected economic impacts from climate change. As explained in the February 2021 SC–GHG TSD, and DOE agrees, this update reflects the immediate need to have an operational SC–GHG for use in regulatory benefit- cost analyses and other applications that was developed using a transparent process, peer-reviewed methodologies, and the science available at the time of that process. Those estimates were subject to public comment in the context of dozens of proposed rulemakings as well as in a dedicated public comment period in 2013. 
There are a number of limitations and 
uncertainties associated with the SC– GHG estimates. First, the current scientific and economic understanding of discounting approaches suggests discount rates appropriate for intergenerational analysis in the context of climate change are likely to be less than 3 percent, near 2 percent or lower.
86Second, the IAMs used to produce these interim estimates do not 
include all of the important physical, ecological, and economic impacts of climate change recognized in the climate change literature and the science underlying their ‘‘damage functions’’—i.e., the core parts of the 
IAMs that map global mean temperature changes and other physical impacts of climate change into economic (both market and nonmarket) damages—lags behind the most recent research. For example, limitations include the incomplete treatment of catastrophic and non-catastrophic impacts in the integrated assessment models, their incomplete treatment of adaptation and technological change, the incomplete way in which inter-regional and intersectoral linkages are modeled, uncertainty in the extrapolation of damages to high temperatures, and inadequate representation of the relationship between the discount rate and uncertainty in economic growth over long time horizons. Likewise, the socioeconomic and emissions scenarios used as inputs to the models do not reflect new information from the last decade of scenario generation or the full range of projections. The modeling limitations do not all work in the same direction in terms of their influence on the SC–CO
2estimates. However, as 
discussed in the February 2021 SC–GHG TSD, the IWG has recommended that, taken together, the limitations suggest that the interim SC–GHG estimates used in this direct final rule likely underestimate the damages from GHG emissions. DOE concurs with this assessment. 
DOE’s derivations of the SC–CO
2, SC– 
N2O, and SC–CH 4values used for this 
NOPR are discussed in the following sections, and the results of DOE’s analyses estimating the benefits of the reductions in emissions of these GHGs are presented in section V.B.6 of this document.

For 2051 to 2070, DOE used SC–CO 2 
estimates published by EPA, adjusted to 
2020$.88These estimates are based on 
methods, assumptions, and parameters identical to the 2020–2050 estimates published by the IWG (which were based on EPA modeling). DOE expects 
additional climate benefits to accrue for any longer-life refrigerators, refrigerator- freezers, and freezers after 2070, but a lack of available SC–CO
2estimates for 
emissions years beyond 2070 prevents DOE from monetizing these potential benefits in this analysis. 
DOE multiplied the CO
2emissions 
reduction estimated for each year by the SC–CO 2value for that year in each of 
the four cases. DOE adjusted the values to 2022$ using the implicit price deflator for gross domestic product (‘‘GDP’’) from the Bureau of Economic Analysis. To calculate a present value of the stream of monetary values, DOE discounted the values in each of the four cases using the specific discount rate that had been used to obtain the SC–CO
2values in each case.

The SC–CH

2.

DOE multiplied the CH 4and N 2O 
emissions reduction estimated for each 
year by the SC–CH 4and SC–N 2O 
estimates for that year in each of the cases. DOE adjusted the values to 2022$ using the implicit price deflator for gross domestic product (‘‘GDP’’) from the Bureau of Economic Analysis. To calculate a present value of the stream 
of monetary values, DOE discounted the values in each of the cases using the 
specific discount rate that had been used to obtain the SC–CH
4and SC–N 2O 
estimates in each case. 
2. Monetization of Other Emissions 
Impacts 
For the direct final rule, DOE 
estimated the monetized value of NO X 
and SO 2emissions reductions from electricity generation using benefit-per- 
ton estimates for that sector from the EPA’s Benefits Mapping and Analysis Program.
89DOE used EPA’s values for 
PM 2.5-related benefits associated with 
NO Xand SO 2and for ozone-related 
benefits associated with NO Xfor 2025, 
2030, and 2040, calculated with discount rates of 3 percent and 7 
percent. DOE used linear interpolation

in the 2025 to 2040 period; for years beyond 2040, the values are held constant. DOE combined the EPA benefit-per-ton estimates with regional information on electricity consumption and emissions to define weighted- average national values for NO
Xand 
SO 2as a function of sector (see 
appendix 14B of the NOPR TSD). 
DOE multiplied the site emissions 
reduction (in tons) in each year by the associated $/ton values, and then discounted each series using discount rates of 3 percent and 7 percent as appropriate. 
M. Utility Impact Analysis 
The utility impact analysis estimates 
the changes in installed electrical 
capacity and generation projected to result for each considered TSL. The analysis is based on published output from the NEMS associated with AEO2023. NEMS produces the AEO 
Reference case, as well as a number of side cases that estimate the economy- wide impacts of changes to energy supply and demand. For the current 
analysis, impacts are quantified by comparing the levels of electricity sector generation, installed capacity, fuel consumption and emissions in the AEO2023 Reference case and various 
side cases. Details of the methodology are provided in the appendices to chapters 13 and 15 of the direct final rule TSD. 
The output of this analysis is a set of 
time-dependent coefficients that capture the change in electricity generation, primary fuel consumption, installed capacity and power sector emissions due to a unit reduction in demand for a given end use. These coefficients are multiplied by the stream of electricity savings calculated in the NIA to provide estimates of selected utility impacts of potential new or amended energy conservation standards. 
N. Employment Impact Analysis 
DOE considers employment impacts 
in the domestic economy as one factor 
in selecting a standard. Employment impacts from new or amended energy conservation standards include both direct and indirect impacts. Direct employment impacts are any changes in the number of employees of manufacturers of the products subject to standards. The MIA addresses those impacts. Indirect employment impacts are changes in national employment that occur due to the shift in expenditures and capital investment caused by the purchase and operation of more efficient appliances. Indirect employment impacts from standards consist of the net jobs created or 
eliminated in the national economy, other than in the manufacturing sector being regulated, caused by (1) reduced spending by consumers on energy, (2) reduced spending on new energy supply by the utility industry, (3) increased consumer spending on the products to which the new standards apply and other goods and services, and (4) the effects of those three factors throughout the economy. 
One method for assessing the possible 
effects on the demand for labor of such shifts in economic activity is to compare sector employment statistics developed by the Labor Department’s Bureau of Labor Statistics (‘‘BLS’’). BLS regularly publishes its estimates of the number of jobs per million dollars of economic activity in different sectors of the economy, as well as the jobs created elsewhere in the economy by this same economic activity. Data from BLS indicate that expenditures in the utility sector generally create fewer jobs (both directly and indirectly) than expenditures in other sectors of the economy.
90There are many reasons for 
these differences, including wage differences and the fact that the utility sector is more capital-intensive and less labor-intensive than other sectors. Energy conservation standards have the effect of reducing consumer utility bills. Because reduced consumer expenditures for energy likely lead to increased expenditures in other sectors of the economy, the general effect of efficiency standards is to shift economic activity from a less labor-intensive sector (i.e., the utility sector) to more 
labor-intensive sectors (e.g., the retail 
and service sectors). Thus, the BLS data suggest that net national employment may increase due to shifts in economic activity resulting from energy conservation standards. 
DOE estimated indirect national 
employment impacts for the standard levels considered in this direct final rule using an input/output model of the U.S. 
economy called Impact of Sector Energy Technologies version 4 (‘‘ImSET’’).
91 
ImSET is a special-purpose version of the ‘‘U.S. Benchmark National Input- Output’’ (‘‘I–O’’) model, which was designed to estimate the national employment and income effects of 
energy-saving technologies. The ImSET software includes a computer-based I–O model having structural coefficients that characterize economic flows among 187 sectors most relevant to industrial, commercial, and residential building energy use. 
DOE notes that ImSET is not a general 
equilibrium forecasting model, and that the uncertainties involved in projecting employment impacts, especially changes in the later years of the analysis. Because ImSET does not incorporate price changes, the employment effects predicted by ImSET may over-estimate actual job impacts over the long run for this rule. Therefore, DOE used ImSET only to generate results for near-term timeframes (2029/30–2033/4), where these uncertainties are reduced. For more details on the employment impact analysis, see chapter 16 of the direct 
final rule TSD. 
O. Other Comments 
As discussed previously, DOE 
considered relevant comments, data, 
and information obtained during its own rulemaking process in determining whether the recommended standards from the Joint Agreement are in accordance with 42 U.S.C. 6295(o). And while some of those comments were directed at specific aspects of DOE’s analysis of the Joint Agreement under 
42 U.S.C. 6295(o), others were more generally applicable to DOE’s energy conservation standards rulemaking program as a whole. The ensuing discussion focuses on these general comments concerning energy conservation standards issued under EPCA. 
1. Commerce Clause 
The AGs of TN, AL, et al. commented 
that DOE’s approach to Congress’s 
Commerce Clause is improper because precedent dictates that Congress can only regulate intrastate activity under the Commerce Clause when that activity ‘‘substantially affects interstate commerce.’’ (AGs of TN, AL, et al., No. 0068 at pp. 3–5) The AGs of TN, AL, et al. commented that for the proposed 
standards to reach the intrastate market for refrigerators, refrigerator-freezers, and freezers, DOE must show that the intrastate activity covered by 42 U.S.C. 6291(17) and 6302(5) substantially affects the interstate market for those products and the proposed standards show no constitutional basis for applying the standards to intrastate commerce in refrigerators, refrigerator- freezers, and freezers. (Id.) The AGs of TN, AL, et al. added that if such an

and Medicine. 2021. Review of Methods Used by the 
U.S. Department of Energy in Setting Appliance and Equipment Standards. Washington, DC: The National Academies Press. Available at doi.org/ 10.17226/25992 (last accessed August 2, 2023). analysis showed the intrastate market 
did not substantially affect the interstate market (and so was not properly the subject of Federal regulation), then DOE would be obligated to redo its cost- benefit analysis since the proposed standards would apply to a more limited set of products—those traveling interstate. (Id.) Finally, the AGs of TN, AL, et al. requested that even if DOE 
found that the intrastate market substantially affected interstate commerce, DOE should nevertheless exclude intrastate activities from the proposed standards to ‘‘maintain a healthy balance of power between the States and the Federal Government.’’ (Id. at 4–5) 
DOE responds that it believes the 
scope of both the standard proposed in the NOPR and the amended standard adopted in this direct final rule properly includes all refrigerators, refrigerator- freezers, and freezers distributed in commerce for personal use or consumption because intrastate state activity regulated by 42 U.S.C. 6291(17) and 6302 is inseparable from and substantially affects interstate commerce. DOE has clear authority under EPCA to regulate the energy use of a variety of consumer products and certain commercial and industrial equipment, including the subject refrigerators, refrigerator-freezers, and freezers. See 42 U.S.C. 6295. Based on 
this statutory authority, DOE has a long- standing practice of issuing standards with the same scope as the standard in this direct final rule. For example, DOE has maintained a similar scope of products in the final rule that established the current standards for refrigerators, refrigerator-freezers, and freezers, which was published on September 15, 2011 (76 FR 57516), and in the final rule establishing the preceding set of standards for these products, published on April 28, 1997 (62 FR 23102). DOE disagrees with the AGs of TN, AL, et al.’s contention that the Commerce Clause, the Tenth Amendment, the Major Questions Doctrine, or any canons of statutory 
construction limit DOE’s clear and long- standing authority under EPCA to adopt the standard, including its scope, in this direct final rule. A further discussion regarding the AGs of TN, AL, et al.’s federalism concerns can be found at section VI.E of this document. 
2. National Academy of Sciences Report 
The National Academies of Sciences, 
Engineering, and Medicine (‘‘NAS’’) 
periodically appoint a committee to peer review the assumptions, models, and methodologies that DOE uses in setting energy conservation standards for covered products and equipment. 
The most recent such peer review was conducted in a series of meetings in 2020, and NAS issued the report
92in 
2021 detailing its findings and recommendations on how DOE can improve its analyses and align them with best practices for cost-benefit analysis. 
AHAM stated that despite previous 
requests from AHAM and others, DOE has failed to review and incorporate the recommendations of the NAS report, instead indicating that it will conduct a separate rulemaking process without such a process having been initiated. (AHAM, No. 69 at pp. 9–10) AHAM further stated that DOE seems to be ignoring the recommendations in the NAS Report and even conducting analysis that is opposite to the recommendations. AHAM commented that DOE cannot continue to perpetuate the errors in its analytical approach that have been pointed out by stakeholders and the NAS report as to do so will lead to arbitrary and capricious rules. (Id.) 
As discussed, the rulemaking process 
for establishing new or amended standards for covered products and equipment are specified at appendix A to subpart C of 10 CFR part 430. DOE periodically examines and revises these provisions in separate rulemaking 
proceedings. The recommendations provided in the 2011 NAS report, which pertain to the processes by which DOE analyzes energy conservation standards, will be considered by DOE in a separate rulemaking process. 
3. Family Well-Being 
The AGs of TN, AL, et al. submitted 
a joint comment that DOE’s proposed 
standards regulate an appliance that is commonly used in family kitchens, and the costs they impose affect every family’s budget, forcing lower-income families to make difficult financial decisions. Therefore, the AGs of TN, AL, et al. requested that DOE provide the assessment required by section 654 of the Treasury and General Government Appropriations Act, 1999, which considers the impact of the Proposed Standards on family well-being. (The AGs of TN, AL, et al., No. 68 at pp. 5– 6) 
Section 654 of the Treasury and 
General Government Appropriations Act, 1999 (Pub. L. 105–277) requires Federal agencies to issue a Family Policymaking Assessment for any proposed rule or policy that may affect 
family well-being. Although this direct final rule would not have any impact on the autonomy or integrity of the family as an institution as defined, this rule could impact a family’s well-being. When developing a Family Policymaking Assessment, agencies must assess whether: (1) the action strengthens or erodes the stability or safety of the family and, particularly, the marital commitment; (2) the action strengthens or erodes the authority and rights of parents in the education, nurture, and supervision of their children; (3) the action helps the family perform its functions, or substitutes governmental activity for the function; (4) the action increases or decreases disposable income or poverty of families and children; (5) the proposed benefits of the action justify the financial impact on the family; (6) the action may be carried out by State or local government or by the family; and whether (7) the action establishes an implicit or explicit policy concerning the relationship between the behavior and personal responsibility of youth, and the norms of society. 
DOE has considered how the 
proposed benefits of this rule compare to the possible financial impact on a family (the only factor listed that is relevant to this rule). As part of its rulemaking process, DOE must determine whether the energy conservation standards contained in this direct final rule are economically justified. As discussed in section V.C.1 of this document, DOE has determined that the standards are economically justified because the benefits to consumers far outweigh the costs to manufacturers. Families will also see LCC savings as a result of this rule. Moreover, as discussed further in section V.B.1 of this document, DOE has determined that for the for low-income households, average LCC savings and PBP at the considered efficiency levels are improved (i.e., higher LCC savings 
and lower payback period) as compared to the average for all households. Further, the standards will also result in climate and health benefits for families. Numerous individuals commented against proposed standards. Comments cited cost increases on consumers, narrowing of consumer choice, and government overregulation. (Individual Commenters, No. 47–53, 56, 58, 59 at p. 1) 
As discussed in section II.A of this 
document, DOE conducted numerous analyses in support of this direct final rule consistent with EPCA, which 
requires that DOE consider many factors, including those concerns raised 
VerDate Sep<11>2014 19:16 Jan 16, 2024 Jkt 262001 PO 00000 Frm 00053 Fmt 4701 Sfmt 4700 E:\FR\FM\17JAR2.SGM 17JAR2lotter on DSK11XQN23PROD with RULES23078 Federal Register / Vol. 89, No. 11 / Wednesday, January 17, 2024 / Rules and Regulations 
by commenters. Analyses include the 
potential negative impacts on consumers and manufacturers and an assessment of the impact relative to the cost and energy savings resulting from amended standards, which are discussed in further detail in sections IV.F, IV.H, and IV.J of this document. DOE conducted its engineering analysis to determine standards that are applicable to reducing energy 
consumption while remaining technologically feasible. The engineering analysis is discussed in greater detail throughout section IV.C of this document. DOE notes that the comments on government overregulation lack the necessary specificity to properly address them in this context. However, as mentioned above, DOE conducted the analysis in this rulemaking consistent with the requirements in EPCA and those used in past rulemakings for this product. 
V. Analytical Results and Conclusions 
The following section addresses the 
results from DOE’s analyses with 
respect to the considered energy conservation standards for refrigerators, refrigerator-freezers, and freezers. It addresses the TSLs examined by DOE, the projected impacts of each of these levels if adopted as energy conservation standards for refrigerators, refrigerator- freezers, and freezers, and the standards levels that DOE is adopting in this direct 
final rule. Additional details regarding DOE’s analyses are contained in the direct final rule TSD supporting this document. 
A. Trial Standard Levels 
In general, DOE typically evaluates 
potential amended standards for 
products and equipment by grouping individual efficiency levels for each class into TSLs. Use of TSLs allows DOE to identify and consider manufacturer cost interactions between the product classes, to the extent that there are such interactions, and market cross elasticity from consumer purchasing decisions that may change when different standard levels are set. 
In the analysis conducted for this 
direct final rule, DOE analyzed the benefits and burdens of six TSLs for refrigerators, refrigerator-freezers, and freezers. DOE developed TSLs that combine efficiency levels for each analyzed product class. TSL 1 represents a modest increase in efficiency, corresponding to the lowest analyzed efficiency level above the baseline for each analyzed product class. TSL 2 represents an increase in efficiency of 10 percent across the product classes analyzed, consistent with ENERGY STAR requirements, except for PC 10, for which a majority of consumers would experience a net cost at all considered ELs. Efficiency improvements for product class 10 were 
considered only for TSL 1 and max-tech TSL 6. TSL 3 increases the stringency for PCs 5, 5A, 7, 11A, and 18 and increases NES while keeping economic impacts on consumers relatively modest. TSL 4 is the Recommended TSL detailed in the Joint Agreement. TSL 4 increases the proposed standard level 
for PCs 3 and 9, as well as the expected NES, while average LCC savings are positive for every product class. TSL 4 also corresponds to different compliance years than the other TSLs. Rather than a compliance year of 2027, for TSL 4, 2029 is the compliance year for the product classes listed in Table I.1 and 2030 is the compliance year for the product classes listed in Table I.2. TSL 5 increases the proposed standard level for PC 5A and PC 7, decreases the proposed standard level for PC 9, and increases the expected overall NES, while average LCC savings remain positive for every product class. TSL 6 represents max-tech. DOE presents the results for the TSLs in this document, while the results for all efficiency levels that DOE analyzed are in the direct final rule TSD. 
Table V.1 presents the TSLs and the 
corresponding efficiency levels that DOE has identified for potential amended energy conservation standards for refrigerators, refrigerator-freezers, and freezers.

and 12. The compliance year varies by product class. See the Joint Agreement for details. 
Section IV.C.3 shows the design 
options determined to be required for 
representative products of each analyzed class as a function of the TSLs. 
B. Economic Justification and Energy 
Savings 
1. Economic Impacts on Individual 
Consumers 
DOE analyzed the economic impacts 
on refrigerator, refrigerator-freezer, and freezer consumers by looking at the effects that potential amended standards at each TSL would have on the LCC and PBP. DOE also examined the impacts of potential standards on selected consumer subgroups. These analyses are discussed in the following sections. a. Life-Cycle Cost and Payback Period 
In general, higher-efficiency products 
affect consumers in two ways: (1) purchase price increases and (2) annual operating costs decrease. Inputs used for calculating the LCC and PBP include total installed costs (i.e., product price 
plus installation costs), and operating costs (i.e., annual energy use, energy 
prices, energy price trends, repair costs, and maintenance costs). The LCC calculation also uses product lifetime and a discount rate. Chapter 8 of the direct final rule TSD provides detailed information on the LCC and PBP analyses. 
Tables V.2 through V.21 show the 
LCC and PBP results for the TSLs considered for each product class. In the 
first of each pair of tables, the simple payback is measured relative to the baseline product. In the second table, the impacts are measured relative to the efficiency distribution in the in the no- new-standards case in the compliance year (see section IV.F.9 of this 
document). Because some consumers purchase products with higher efficiency in the no-new-standards case, the average savings are less than the difference between the average LCC of the baseline product and the average 
LCC at each TSL. The savings refer only to consumers who are affected by a standard at a given TSL. Those who already purchase a product with

efficiency at or above a given TSL are 
not affected. Consumers for whom the LCC increases at a given TSL experience a net cost.

b. Consumer Subgroup Analysis 
In the consumer subgroup analysis, 
DOE estimated the impact of the 
considered TSLs on low-income 
households and small businesses. Table V.22 compares the average LCC savings and PBP at each efficiency level for the low-income consumer subgroup with similar metrics for the entire consumer sample for PCs 3, 7, 9, and 10 (see 
section IV.I for an explanation of why other product classes are excluded). Table V.23 provides a similar comparison for PC 11A for the small business subgroup. In all cases, the average LCC savings and PBP for low- 
income households at the considered efficiency levels are improved (i.e., higher LCC savings and lower payback 
period) from the average for all households. The LCC savings and payback period results for the small business subgroup for PC 11A are similar to those for all businesses. Chapter 11 of the direct final rule TSD 
presents the complete LCC and PBP results for the subgroups.

c. Rebuttable Presumption Payback 
As discussed in section IV.F.10 of this 
document, EPCA establishes a 
rebuttable presumption that an energy conservation standard is economically justified if the increased purchase cost for a product that meets the standard is less than three times the value of the 
first-year energy savings resulting from the standard. In calculating a rebuttable- presumption payback period for each of the considered TSLs, DOE used discrete values, and, as required by EPCA, based the energy use calculation on the DOE 
test procedures for refrigerators, refrigerator-freezers, and freezers. In contrast, the PBPs presented in section V.B.1.a of this document were calculated using distributions that reflect the range of energy use in the field. 
Table V.24 presents the rebuttable- 
presumption payback periods for the considered TSLs for refrigerators, refrigerator-freezers, and freezers. While DOE examined the rebuttable- presumption criterion, it considered whether the standard levels considered for this rule are economically justified through a more detailed analysis of the economic impacts of those levels, pursuant to 42 U.S.C. 6295(o)(2)(B)(i), that considers the full range of impacts to the consumer, manufacturer, Nation, and environment. The results of that analysis serve as the basis for DOE to definitively evaluate the economic justification for a potential standard level, thereby supporting or rebutting the results of any preliminary determination of economic justification.

2. Economic Impacts on Manufacturers 
DOE performed an MIA to estimate 
the impact of amended energy conservation standards on manufacturers of refrigerators, refrigerator-freezers, and freezers. The next section describes the expected impacts on manufacturers at each considered TSL. Chapter 12 of the direct final rule TSD explains the analysis in further detail. 
a. Industry Cash Flow Analysis Results 
In this section, DOE provides GRIM 
results from the analysis, which 
examines changes in the industry that would result from a standard. The following tables summarize the estimated financial impacts (represented by changes in INPV) of potential amended energy conservation standards on manufacturers of refrigerators, refrigerator-freezers, and freezers, as well as the conversion costs that DOE estimates manufacturers of refrigerators, 
refrigerator-freezers, and freezers would incur at each TSL. 
The impact of potential amended 
energy conservation standards was analyzed under two scenarios: (1) the preservation-of-gross-margin percentage; 
and (2) the preservation-of-operating- profit, as discussed in section IV.J.2.d of this document. The preservation-of- gross-margin percentages applies a ‘‘gross margin percentage’’ of 21 percent for all freestanding product classes and 29 percent for all built-in product classes, across all efficiency levels.
93 
This scenario assumes that a manufacturer’s per-unit dollar profit would increase as MPCs increase in the standards cases and represents the upper-bound to industry profitability under potential new or amended energy 
conservation standards. 
The preservation-of-operating-profit 
scenario reflects manufacturers’ concerns about their inability to maintain margins as MPCs increase to reach more stringent efficiency levels. In this scenario, while manufacturers make the necessary investments required to convert their facilities to produce compliant products, operating profit does not change in absolute dollars and decreases as a percentage of revenue. The preservation-of-operating-profit scenario results in the lower (or more severe) bound to impacts of potential amended standards on industry. 
Each of the modeled scenarios results 
in a unique set of cash flows and corresponding INPV for each TSL. INPV is the sum of the discounted cash flows to the industry from the base year through the end of the analysis period (30 years from the analyzed compliance

94The analysis period ranges from 2023–2056 for 
the no-new-standards case and all TSLs, except for 
TSL 4 (the Recommended TSL). The analysis period for the Recommended TSL ranges from 2023–2058 for the product classes listed in Table I.1 and 2023– 
2059 for the product classes listed in Table I.2. 
95The engineering analysis modeled PC 5 (23.0 
AV) as requiring a higher-efficiency single-speed compressor to meet TSL 1 efficiencies and modeled 
PC 5 (30.0 AV) as requiring a variable-speed compressor system to meet TSL 1 efficiencies. year).94The ‘‘change in INPV’’ results 
refer to the difference in industry value 
between the no-new-standards case and standards case at each TSL. To provide perspective on the short-run cash flow impact, DOE includes a comparison of free cash flow between the no-new- standards case and the standards case at 
each TSL in the year before amended standards would take effect. This figure provides an understanding of the magnitude of the required conversion costs relative to the cash flow generated by the industry in the no-new-standards case. 
Conversion costs are one-time 
investments for manufacturers to bring their manufacturing facilities and product designs into compliance with potential amended standards. As described in section IV.J.2.c of this document, conversion cost investments occur between the year of publication of the direct final rule and the year by which manufacturers must comply with 
the new standard. The conversion costs can have a significant impact on the short-term cash flow of the industry and generally result in lower free cash flow in the period between the publication of the direct final rule and the compliance date of potential amended standards. Conversion costs are independent of the manufacturer markup scenarios and are not presented as a range in this analysis.

** TSL 4 (i.e., the Recommended TSL) represents the change in free cash flow in 2029. 
*** In 2029, the no-new-standards case free cash flow is $413.1 million. 
The following cash flow discussion 
refers to product classes as defined in 
Table I.1 in section I of this document and the efficiency levels and design options as detailed in Tables IV.5 through IV.7 in section IV.C.3 of this document. 
At TSL 1, the standard represents a 
modest increase in efficiency, corresponding to the lowest analyzed efficiency level above the baseline for each analyzed product class. The change in INPV is expected to range from ¥1.3 to ¥0.3 percent. At this 
level, free cash flow is estimated to decrease by 7.0 percent compared to the no-new-standards case value of $414.5 million in the year 2026, the year before the 2027 standards year. Currently, approximately 24 percent of domestic refrigerator, refrigerator-freezer, and freezer shipments meet the efficiencies required at TSL 1. See Table V.27 for the 
percentage of 2023 shipments that meet each TSL by product class. 
The design options DOE analyzed 
primarily included implementing more efficient single-speed compressors. For PC 5,
95PC 5A, PC 5–BI, PC 10, and PC 
17, the design options analyzed included implementing higher- efficiency variable-speed compressors. DOE also analyzed implementing BLDC fan motors and variable defrost for some 
product classes. DOE expects manufacturers would likely need to increase wall thickness for some of PC 11A models to meet TSL 1 efficiencies. At this level, capital conversion costs are minimal since most manufacturers can achieve TSL 1 efficiencies with 
relatively minor component changes. Product conversion costs may be necessary for developing, qualifying, sourcing, and testing new components. DOE expects industry to incur some re- flooring costs as manufacturers redesign baseline products to meet the efficiency levels required by TSL 1. DOE estimates capital conversion costs of $10.8 million and product conversion costs of $71.7 million. Conversion costs total $82.5 million. 
At TSL 1, the shipment-weighted 
average MPC for all refrigerators, refrigerator-freezers, and freezers is expected to increase by 1.6 percent relative to the no-new-standards case shipment-weighted average MPC for all refrigerators, refrigerator-freezers, and freezers in 2027. In the preservation-of- gross-margin percentage scenario, the minor increase in cashflow from the higher MSP is slightly outweighed by the $82.5 million in conversion costs, causing a negligible change in INPV at TSL 1 under this scenario. Under the 
preservation-of-operating-profit scenario, manufacturers earn the same per-unit operating profit as would be earned in the no-new-standards case, but manufacturers do not earn additional profit from their investments. In this scenario, the manufacturer 
markup decreases in 2028, the year after the analyzed 2027 compliance year. This reduction in the manufacturer markup and the $82.5 million in conversion costs incurred by manufacturers cause a slightly negative change in INPV at TSL 1 under the preservation-of-operating-profit scenario. See section IV.J.2.d of this 
document for details on the manufacturer markup scenarios. 
At TSL 2, the standard represents an 
increase in efficiency of approximately 10 percent across all analyzed product classes, consistent with ENERGY STAR requirements, except for PC 10. The change in INPV is expected to range from ¥2.2 to ¥0.7 percent. At this 
level, free cash flow is estimated to decrease by 12.4 percent compared to the no-new-standards case value of $414.5 million in the year 2026, the year before the 2027 standards year. Currently, approximately 26 percent of domestic refrigerator, refrigerator-

96For the Recommended TSL, the compliance 
year varies by product class. For the product classes 
listed in Table I.1, the analyzed compliance year is 2029. For the product classes listed in Table I.2, the analyzed compliance year is 2030. The product classes associated with the 2030 compliance year account for approximately 68 percent of total shipments. freezer, and freezer shipments meet the 
efficiencies required at TSL 2. 
The design options DOE analyzed 
include implementing similar design options as TSL 1, such as more efficient compressors, BLDC fans, and variable defrost. For PC 3, the design options included implementing incrementally more efficient single-speed compressors and variable defrost. For PC 7, the design options analyzed included implementing variable-speed compressors. For PC 3 and PC 7, TSL 2 corresponds to EL 2. For PC 10, TSL 2 corresponds to baseline efficiency. For the remaining product classes, the efficiencies required at TSL 2 are the same as TSL 1. The increase in conversion costs from the prior TSL is entirely due to the increased efficiencies required for PC 3 and PC 7. Capital conversion costs may be necessary for updated tooling and additional stations to test more variable-speed compressors. Product conversion costs may be necessary for developing, qualifying, sourcing, and testing variable-speed compressors and associated electronics. DOE expects industry to incur slightly more re-flooring costs compared to TSL 1. DOE estimates capital conversion costs of $22.3 million and product conversion costs of $121.7 million. Conversion costs total $144.0 million. 
At TSL 2, the shipment-weighted 
average MPC for all refrigerators, refrigerator-freezers, and freezers is expected to increase by 2.3 percent relative to the no-new-standards case shipment-weighted average MPC for all refrigerators, refrigerator-freezers, and freezers in 2027. In the preservation-of- gross-margin-percentage scenario, the slight increase in cashflow from the higher MSP is outweighed by the $144.0 million in conversion costs, causing a slightly negative change in INPV at TSL 2 under this scenario. Under the preservation-of-operating-profit scenario, the manufacturer markup decreases in 2028. This reduction in the manufacturer markup and the $144.0 million in conversion costs incurred by manufacturers cause a slightly negative change in INPV at TSL 2 under the preservation-of-operating-profit scenario. 
At TSL 3, the standard represents an 
increased stringency for PC 5, PC 5A, PC 7, PC 11A, and PC 18 and increased 
NES while keeping economic impacts on consumers modest. The change in INPV is expected to range from ¥10.6 to ¥8.0 percent. At this level, free cash 
flow is estimated to decrease by 66.7 percent compared to the no-new- standards case value of $414.5 million in the year 2026, the year before the 2027 standards year. Currently, approximately 18 percent of domestic 
refrigerator, refrigerator-freezer, and freezer shipments meet the efficiencies required at TSL 3. 
In addition to the design options DOE 
analyzed at TSL 2, the design options analyzed for PC 5 include implementing higher-efficiency variable-speed compressors and incorporating partial VIP for larger capacity (i.e., adjusted 
volume) products. DOE expects that PC 5A products would likely also need to incorporate some partial VIP. For PC 7, the deign options analyzed included implementing more efficient variable- speed compressors. Additionally, for the compact-size PC 18, DOE expects manufacturers may need to increase cabinet wall thickness. For PC 5, PC 5A, PC 11A, and PC 18, TSL 3 corresponds to EL 2. For PC 7, TSL 3 corresponds to EL 3. For the remaining product classes, the efficiencies required at TSL 3 are the same as TSL 2. The increase in conversion costs from the prior TSL are driven by the efficiencies required for PC 5 and PC 5A due to their large market share (together, these product classes account for approximately 30 percent of total shipments) and the design options required to meet this level. Capital conversion costs may be necessary for new tooling for VIP placement as well as new testing stations for high-efficiency components. Product conversion costs may be necessary for developing, qualifying, sourcing, and testing new components. For products implementing VIPs, product conversion costs may be necessary for prototyping and testing for VIP placement, design, and sizing. 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. DOE expects industry to incur re-flooring costs as manufacturers redesign their products to meet the efficiency levels required by TSL 3. DOE estimates capital conversion costs of $378.1 million and product conversion costs of $314.7 million. Conversion costs total $629.8 million. 
At TSL 3, the shipment-weighted 
average MPC for all refrigerators, refrigerator-freezers, and freezers is 
expected to increase by 4.0 percent relative to the no-new-standards case shipment-weighted average MPC for all 
refrigerators, refrigerator-freezers, and freezers in 2027. In the preservation-of- gross-margin-percentage scenario, the increase in cashflow from the higher MSP is outweighed by the $692.8 million in conversion costs, causing a negative change in INPV at TSL 3 under this scenario. Under the preservation-of- operating-profit scenario, the manufacturer markup decreases in 2028. This reduction in the manufacturer markup and the $692.8 million in conversion costs incurred by manufacturers cause a negative change in INPV at TSL 3 under the preservation-of-operating-profit scenario. 
At TSL 4 (i.e., the Recommended 
TSL), the standard represents an increased stringency for PC 3 and PC 9, 
as well as the expected NES, while maintaining positive average LCC savings for every analyzed product class. The change in INPV is expected to range from ¥10.3 to ¥7.8 percent. At this level, free cash flow is estimated to decrease by 51.7 percent compared to the no-new-standards case value of $413.1 million in the year 2029, the year before the 2030 standards year.
96 
Currently, approximately 14 percent of domestic refrigerator, refrigerator- freezer, and freezer shipments meet the efficiencies required at TSL 4. 
In addition to the design options DOE 
analyzed at TSL 3, the design options analyzed for PC 3 products include implementing the highest-EER single- speed compressors or variable-speed compressors. For PC 9, the design options analyzed included the highest- EER variable-speed compressors. For PC 3, TSL 4 corresponds to EL 3. For PC 9, TSL 4 corresponds to EL 2. For the remaining directly analyzed product classes, the efficiencies required at TSL 4 are the same as TSL 3. At this level, the increase in conversion costs is entirely driven by the higher efficiency levels required for PC 3 and PC 9, which together account for approximately 33 percent of current industry shipments. Many manufacturers of these product classes would need to update their platforms to integrate variable-speed compressors. 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 industry to incur

97The compliance year for the Recommended 
TSL varies by product class. For PC 1, PC 1A, PC 
2, PC 3, PC 3A, PC 4, PC 5, PC 6, PC 7, and PC 9, the compliance year is 2030. For the remaining product classes, the compliance year is 2029. more re-flooring costs compared to TSL 
3. DOE estimates capital conversion costs of $471.8 million and product conversion costs of $358.5 million. Conversion costs total $830.3 million. 
At TSL 4, the shipment-weighted 
average MPC for all refrigerator, refrigerator-freezers, and freezers is expected to increase by 4.8 percent relative to the no-new-standards case shipment-weighted average MPC for all refrigerators, refrigerator-freezers, and freezers in 2030. In the preservation-of- gross-margin-percentage scenario, the increase in cashflow from the higher MSP is outweighed by the $830.3 million in conversion costs, causing a negative change in INPV at TSL 4 under this scenario. Under the preservation-of- operating-profit scenario, the manufacturer markup decreases in 2031, the year after the analyzed 2030 compliance year.
97This reduction in the 
manufacturer markup and the $830.3 million in conversion costs incurred by manufacturers cause a negative change in INPV at TSL 4 under the preservation-of-operating-profit scenario. 
At TSL 5, the standard represents the 
maximum NPV. The change in INPV is expected to range from ¥21.7 to ¥17.2 percent. At this level, free cash flow is estimated to decrease by 140.1 percent compared to the no-new-standards case value of $414.5 million in the year 2026, the year before the 2027 standards year. Currently, approximately 14 percent of domestic refrigerator, refrigerator- freezer, and freezer shipments meet the efficiencies required at TSL 5. 
In addition to the design options DOE 
analyzed at TSL 4, the design options analyzed for PC 5A includes implementing VIPs on all of the cabinet surface (side walls and doors) and for PC 7 includes implementing VIPs on roughly 75 percent of the cabinet surface. For PC 5A, TSL 5 corresponds to EL 3. For PC 7, TSL 5 corresponds to EL 4. For PC 9, TSL 5 corresponds to EL 1, the same efficiency level required for TSL 3. For the remaining product classes, the efficiencies required at TSL 5 are the same as TSL 4. The increase in conversion costs compared to the prior TSL is entirely driven by the higher efficiency level required for PC 5A and PC 7, which likely necessitates incorporating some VIPs. In interviews, some manufacturers stated that their existing PC 5A and PC 7 platforms cannot reach this efficiency level and would require a platform redesign, which would likely mean new cases, liners, and fixtures. DOE expects slightly more re-flooring costs compared to the prior TSL as manufacturers redesign products to meet the required efficiencies. DOE estimates capital conversion costs of $945.3 million and product conversion costs of $458.7 million. Conversion costs total $1.40 billion. 
At TSL 5, the large conversion costs 
result in a free cash flow dropping below zero in the years before the standards year. The negative free cash flow calculation indicates manufacturers may need to access cash reserves or outside capital to finance conversion efforts. 
At TSL 5, the shipment-weighted 
average MPC for all refrigerators, refrigerator-freezers, and freezers is expected to increase by 7.0 percent relative to the no-new-standards case shipment-weighted average MPC for all refrigerators, refrigerator-freezers, and freezers in 2027. In the preservation-of- gross-margin-percentage scenario, the increase in cashflow from the higher MSP is outweighed by the $1.40 billion in conversion costs, causing a moderately negative change in INPV at TSL 5 under this scenario. Under the preservation-of-operating-profit scenario, the manufacturer markup decreases in 2028. This reduction in the manufacturer markup and the $1.40 billion in conversion costs incurred by manufacturers cause a large decrease in INPV at TSL 5 under the preservation- of-operating-profit scenario. 
At TSL 6, the standard reflects max- 
tech for all product classes. The change in INPV is expected to range from ¥37.2 to ¥26.5 percent. At this level, free cash flow is estimated to decrease by 240.2 percent compared to the no- new-standards case value of $414.5 million in the year 2026, the year before the 2027 standards year. Currently, approximately 0.9 percent of domestic refrigerator, refrigerator-freezer, and freezer shipments meet the efficiencies 
required at TSL 6. 
At max-tech levels, manufacturers 
would likely need to implement the best-available-efficiency VSC, forced- convection heat exchangers with multi- speed 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). Manufacturers would also likely incorporate VIP doors for PC 10 and PC 18 and VIPs for roughly half the cabinet surface (typically side walls and doors for an upright cabinet) for all other classes. At TSL 6, only a few manufacturers offer any products that meet the efficiencies required. For PC 3, which accounts for approximately 25 
percent of annual shipments, no 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 the 11 OEMs currently offers products that meet the efficiency level required. 
The efficiencies required by TSL 6 
could require a major renovation of existing facilities and completely new refrigerator, refrigerator-freezer, and freezer platforms for many OEMs. In interviews, some manufacturers stated that they are physically constrained at their current production location and would therefore need to expand their existing production facility or move to an entirely new facility. These manufacturers stated that their current manufacturing locations are at capacity and cannot accommodate the additional labor required to implement VIPs. DOE expects industry to incur more re- flooring costs compared to TSL 5 as all display models below max-tech efficiency would need to be replaced due to the more stringent standard. DOE estimates capital conversion costs of $1.68 billion and product conversion costs of $711.4 million. Conversion costs total $2.39 billion. 
At TSL 6, the large conversion costs 
result in a free cash flow dropping below zero in the years before the 2027 standards year. The negative free cash flow calculation indicates manufacturers may need to access cash reserves or outside capital to finance conversion efforts. 
At TSL 6, the shipment-weighted 
average MPC for all refrigerators, refrigerator-freezers, and freezers is expected to increase by 16.8 percent relative to the no-new-standards case shipment-weighted average MPC for all refrigerators, refrigerator-freezers, and freezers in 2027. In the preservation-of- gross-margin-percentage scenario, the increase in cashflow from the higher MSP is outweighed by the $2.39 billion in conversion costs, causing a large negative change in INPV at TSL 6 under this scenario. Under the preservation-of- 
operating-profit scenario, the manufacturer markup decreases in 2028. This reduction in the manufacturer markup and the $2.39 billion in conversion costs incurred by manufacturers causes a significant decrease in INPV at TSL 6 under the preservation-of-operating-profit scenario.

b. Direct Impacts on Employment 
To quantitatively assess the potential 
impacts of amended energy 
conservation standards on direct employment in the refrigerators, refrigerator-freezers, and freezers industry, DOE used the GRIM to estimate the domestic labor expenditures and number of direct employees in the no-new-standards case and in each of the standards cases during the analysis period. For the direct final rule, DOE used the most up- to-date information available. DOE calculated these values using statistical data from the 2021 ASM,
98BLS 
employee compensation data,99results 
of the engineering analysis, and manufacturer interviews conducted in support of the February 2023 NOPR. 
Labor expenditures related to product 
manufacturing depend on the labor intensity of the product, the sales volume, and an assumption that wages remain fixed in real terms over time. The total labor expenditures in each year are calculated by multiplying the total MPCs by the labor percentage of MPCs. The total labor expenditures in the GRIM were then converted to total production employment levels by dividing production labor expenditures by the average fully burdened wage multiplied by the average number of hours worked per year per production worker. To do this, DOE relied on the ASM inputs: Production Workers 
Annual Wages, Production Workers 
Annual Hours, Production Workers for Pay Period, and Number of Employees. DOE also relied on the BLS employee compensation data to determine the fully burdened wage ratio. The fully burdened wage ratio factors in paid leave, supplemental pay, insurance, retirement and savings, and legally required benefits. 
The number of production employees 
is then multiplied by the U.S. labor Percentage to convert total production employment to total domestic production employment. The U.S. labor percentage represents the industry fraction of domestic manufacturing production capacity for the covered product. This value is derived from manufacturer interviews, product database analysis, and publicly available information. Consistent with the February 2023 NOPR, DOE estimates that 28 percent of refrigerators, refrigerator-freezers, and freezers are produced domestically. 
The domestic production employees 
estimate covers production line workers, including line supervisors, who are directly involved in fabricating 
and assembling products within the OEM facility. Workers performing services that are closely associated with production operations, such as materials-handling tasks using forklifts, are also included as production labor. DOE’s estimates only account for production workers who manufacture the specific products covered by this rulemaking. 
Non-production workers account for 
the remainder of the direct employment figure. The non-production employees estimate covers domestic workers who are not directly involved in the production process, such as sales, engineering, human resources, and management.
100Using the amount of 
domestic production workers calculated above, non-production domestic employees are extrapolated by multiplying the ratio of non-production workers in the industry compared to production employees. DOE assumes that this employee distribution ratio remains constant between the no-new- standards case and standards cases. 
Using the GRIM, DOE estimates in the 
absence of new energy conservation standards there would be 6,366 domestic production and non- production workers for refrigerators, refrigerator-freezers, and freezers in 2027. Table V.27 shows the range of the impacts of energy conservation standards on U.S. manufacturing employment in the refrigerator, refrigerator-freezer, and freezer industry. The following discussion provides a qualitative evaluation of the range of potential impacts presented in Table V.27.

101The design path analyzed in DOE’s 
engineering analysis for PC 5 with a 3-door 
configuration (adjusted volume of 30 ft3) would 
likely require some VIPs at TSL 4 (EL 2). See section IV.C.2 of this document for the analyzed design options at each efficiency level for the directly analyzed product classes. TABLE V.27—D OMESTIC DIRECT EMPLOYMENT IMPACTS FOR REFRIGERATOR , REFRIGERATOR -FREEZER , ANDFREEZER

* For TSL 4 (the Recommended TSL), the direct employment values reflect 2030 estimates. 
** DOE presents a range of potential employment impacts. Numbers in parentheses denote negative values. 
The direct employment impacts 
shown in Table V.27 represent the 
potential domestic employment changes that could result following the compliance date for the refrigerator, refrigerator-freezer, and freezer product classes in this direct final rule. The upper bound estimate corresponds to an increase in the number of domestic workers that would result from amended energy conservation standards if manufacturers continue to produce the same scope of covered products within the United States after compliance takes effect. The lower bound estimate represents the maximum decrease in production workers if manufacturing moved to lower labor-cost countries. Most manufacturers currently produce at least a portion of their refrigerators, refrigerator-freezers, and freezers in countries with lower labor costs. Adopting an amended standard that necessitates large increases in labor content or large expenditures to re-tool facilities could cause manufacturers to reevaluate domestic production siting options. At the Recommended TSL (TSL 4), DOE expects some manufacturers would need to implement insulation changes (e.g., VIPs and/or increasing 
wall thickness) into certain product classes, which could require additional labor content and capital investment. For the high-volume product classes, DOE expects that PC 5A and some PC 5 models
101would likely require 
implementing partial VIPs to meet TSL 4 efficiencies. DOE estimates the products that would likely require some VIPs to meet TSL 4 efficiencies collectively account for approximately 24 percent of industry shipments. Based on information gathered during confidential manufacturer interviews and public sources, DOE understands that a portion of PC 5 and PC 5A products are currently manufactured in the United States. Although it is possible that amended standards in this rulemaking and other DOE rulemakings could factor into production siting locations due to the level of investment and additional labor content required. However, based on information gathered during confidential manufacturer interviews, DOE does not expect most manufacturers would shift domestic production outside of the United States solely as a result of this direct final rule. 
Additional detail on the analysis of 
direct employment can be found in chapter 12 of the direct final rule TSD. Additionally, the employment impacts discussed in this section are independent of the employment impacts from the broader U.S. economy, which are documented in chapter 16 of the direct final rule TSD. 
c. Impacts on Manufacturing Capacity 
In interviews, some manufacturers 
noted potential capacity concerns 
related to implementing VIPs, particularly for high-volume product lines (i.e., PC 3, PC 5, PC 5A, and PC 
7). These manufacturers noted that incorporating VIPs (or additional VIPs) is labor intensive. Implementing VIPs requires additional labor associated with initial quality control inspections, placement, and post-foam inspections. These manufacturers noted they are physically constrained at some factories and do not have the ability to extend production lines to accommodate additional labor content. As discussed in section V.B.2.a of this document, some manufacturers noted that the only way to maintain current production levels would be to expand the existing footprint, build a mezzanine, or move to a new production facility. In interviews, some manufacturers expressed concerns at the max-tech efficiencies for top- mount (TSL 6), bottom-mount with through-the-door ice service (TSL 5), bottom-mount without through-the-door 
ice service (TSL 6), and side-by-side (TSL 6) standard-size refrigerator- freezers, and stated that the 3-year period between the announcement of the direct final rule and the compliance date of the amended energy conservation standard might be insufficient to update existing plants or build new facilities to accommodate the additional labor required to manufacture the necessary number of products to meet demand. In this direct final rule, DOE adopts TSL 4 (the Recommended TSL). At the adopted level, the max-tech efficiencies are not required for any of the analyzed product classes, including the high-volume product classes manufacturers expressed concerns about during confidential interviews. Furthermore, compliance with amended standards would not be required until 2030 for freestanding top-mount product classes (i.e., PC 1, PC 1A, PC 2, PC 3, PC 3A, 
PC 6), freestanding side-by-side product classes (i.e., PC 4, PC 7), and 
freestanding bottom-mount without through-the-door ice service product class (i.e., PC 5), and 2029 for the 
remaining product classes. Compared to TSLs with a 2027 compliance date, manufacturers would have additional time to update production facilities and redesign products to meet amended standards. The Recommended TSL’s compliance dates would provide manufacturers the opportunity to spread capital requirements, engineering resources, and conversion activities over a longer period of time. 
In response to the February 2023 
NOPR, AHAM, Whirlpool, GEA, and Sub Zero expressed concerns that the supply of high-efficiency components such as VIPs and VSCs would not be able to ramp up in the 3-year compliance period to meet the expected consumer demand for refrigerators, refrigerator-freezers, and freezers. (AHAM, No. 69 at p. 5; Whirlpool, No. 70 at p. 5; GEA, No. 75 at p. 2; and Sub Zero, No. 77 at p. 2) Conversely, Samsung commented that the industry has a significant amount of VSCs available for purchase, and that the 3- year compliance period is acceptable for manufacturers and suppliers to establish sufficient availability of VSCs. (Samsung, No. 78 at p. 3) 
In support of this analysis, DOE 
conducted research and interviewed 
VerDate Sep<11>2014 19:16 Jan 16, 2024 Jkt 262001 PO 00000 Frm 00066 Fmt 4701 Sfmt 4700 E:\FR\FM\17JAR2.SGM 17JAR2lotter on DSK11XQN23PROD with RULES23091 Federal Register / Vol. 89, No. 11 / Wednesday, January 17, 2024 / Rules and Regulations 
VSC and VIP component suppliers to 
gather additional information on the global market capacity for these high- efficiency components. Based on the information gathered, DOE expects that VIP production lines can be quickly scaled up to meet demand of future amended standards (within 1 to 2 years depending on the specific VIP design). For VSCs, based on supplier information on the global refrigerator VSC production capacity, supply constraints, and ramp-up time, DOE determined that the industry can meet the increased demand of VSCs that may result due to the adoption of more stringent standards within the necessary compliance period, with an estimated 8 to 12 month VSC production ramp-up, as needed. 
d. Impacts on Subgroups of 
Manufacturers 
Using average cost assumptions to 
develop industry cash flow estimates may not capture the differential impacts among subgroups of manufacturers. Small manufacturers, niche players, or manufacturers exhibiting a cost structure that differs substantially from the industry average could be affected disproportionately. DOE investigated small businesses as a manufacturer subgroup that could be disproportionally impacted by energy conservation standards and could merit additional analysis. DOE also identified the domestic LVM subgroup as a potential manufacturer subgroup that could be adversely impacted by energy 
conservation standards based on the results of the industry characterization. 
Small Businesses 
DOE analyzes the impacts on small 
businesses in a separate analysis for the 
standards proposed in the NOPR published elsewhere in this issue of the Federal Register and in chapter 12 of the direct final rule TSD. In summary, the Small Business Administration (‘‘SBA’’) defines a ‘‘small business’’ as having 1,500 employees or less for NAICS 335220, ‘‘Major Household Appliance Manufacturing.’’ Based on this classification, DOE identified one domestic OEM that qualifies as a small business. For a discussion of the impacts on the small business manufacturer subgroup, see chapter 12 
of the direct final rule TSD. 
Domestic, Low-Volume Manufacturers 
In addition to the small business 
subgroup, DOE identified domestic 
LVMs as a manufacturer subgroup that may experience differential impacts due to amended standards. DOE identified three domestic LVMs of refrigerators, refrigerator-freezers, and freezers that would potentially face more challenges with meeting amended standards than 
other larger OEMs of the covered products. 
Although these LVMs do not qualify 
as small businesses according to the SBA criteria previously discussed (i.e., employee count exceeds 1,500), these manufacturers are significantly smaller in terms of annual revenues than the larger, diversified manufacturers selling refrigerators, refrigerator-freezers, and freezers in the United States. The domestic LVM subgroup consists of refrigerator, refrigerator-freezer, and freezer manufacturers that primarily sell high-end, built-in or fully integrated consumer refrigeration products (‘‘undercounter’’ and standard-size) as well as miscellaneous refrigeration products, commercial refrigeration equipment, and cooking products. Specifically, manufacturers indicated during confidential interviews that the fully integrated compact (‘‘undercounter’’) products produced by the domestic LVMs are niche products and are more expensive to produce (and, therefore, have higher selling prices) than the majority of the compact products sold in the United States. 
Table V.28 lists the range of product 
offerings and estimated total company annual revenue for the three domestic LVMs identified. These three manufacturers account for approximately 1 percent of the overall domestic refrigerator, refrigerator- freezer, and freezer shipments. This table also contains the range of total company annual revenue for the five largest appliance manufacturers selling refrigerators, refrigerator-freezers, and freezers in the U.S. market. These five appliance manufacturers account for approximately 95 percent of the overall domestic refrigerator, refrigerator- freezer, and freezer shipments.

Large Appliance Manufacturers ...... $15,730 to $164,030 ..................... Wide range of freestanding, standard-size refrigerator-freezers and 
freezers. (e.g., PC 3, PC 5, PC 5A, PC 7, PC 10) Most also offer 
premium brands for standard-size built-in products. 
* Revenue estimates refer to the total annual company revenue of the parent company and any associated subsidiaries. 
LVMs may be disproportionately 
affected by conversion costs. Product redesign, testing, and certification costs tend to be fixed per basic model and do not scale with sales volume. Both large manufacturers and LVMs must make investments in R&D to redesign their products, but LVMs lack the sales volumes to sufficiently recoup these upfront investments without substantially marking up their products’ selling prices. LVMs may also face challenges related to purchasing power and a less robust supply chain for key technologies or components, as compared to larger manufacturers. DOE notes that domestic LVMs have access to the same technology options as larger appliance manufacturers, the challenge with redesigning products to meet amended standards relates to scale and their ability to recover investments necessitated by more stringent standards. 
Although domestic, low-volume 
manufacturers would likely face additional challenges meeting amended standards for the built-in and compact (‘‘undercounter’’) refrigerator, refrigerator-freezer, and freezer product classes compared to other refrigerator, refrigerator-freezer, and freezer manufacturers, some of the adopted amendments may be beneficial for domestic LVMs. As discussed in section IV.A.1 of this document, DOE is proposing to incorporate certain energy use allowances for products with special doors and multi-door designs. A review of the three domestic LVM’s product offerings and information gathered in confidential interviews

indicates transparent door designs are 
particularly prevalent in their products. See section IV.A.1 of this document for 
additional details on energy use allowances for products with special 
doors and multi-door designs. 
e. Cumulative Regulatory Burden 
One aspect of assessing manufacturer 
burden involves looking at the 
cumulative impact of multiple DOE standards and the regulatory actions of other Federal agencies and States that affect the manufacturers of a covered product or equipment. While any one 
regulation may not impose a significant burden on manufacturers, the combined effects of several existing or impending regulations may have serious consequences for some manufacturers, groups of manufacturers, or an entire industry. Multiple regulations affecting the same manufacturer can strain profits and lead companies to abandon product lines or markets with lower expected future returns than competing products. For these reasons, DOE conducts an analysis of cumulative regulatory burden as part of its rulemakings pertaining to appliance efficiency. 
For the cumulative regulatory burden 
analysis, DOE examines Federal, product-specific regulations that could affect refrigerator, refrigerator-freezer, and freezer manufacturers that take effect approximately 3 years before the 2029 compliance date and 3 years after the after the 2030 compliance date (2026 to 2033). This information is presented in Table V.29.

of the national energy savings and the NPV of consumer benefits that would result from each of the TSLs considered as potential amended standards. 
a. Significance of Energy Savings 
To estimate the energy savings 
attributable to potential amended standards for refrigerators, refrigerator- 
freezers, and freezers, DOE compared their energy consumption under the no- new-standards case to their anticipated energy consumption under each TSL. The savings are measured over the entire lifetime of products purchased in the 30-year period that begins in the 
year of anticipated compliance with amended standards (2027–2056 for all TSLs other than TSL 4; for TSL 4, 2029– 
2058 for the product classes listed in Table I.1 and 2030–2059 for the product classes listed in Table I.2). Tables V.30 and V.31 present DOE’s projections of the national energy savings for each TSL considered for refrigerators, refrigerator- freezers, and freezers. The savings were 
calculated using the approach described in section IV.H.2 of this document.

Circular A–4: Regulatory Analysis. Available at 
https://www.whitehouse.gov/omb/information-for- agencies/circulars/ (last accessed July 13, 2023). 
DOE used the prior version of Circular A–4 (2003) as a result of the effective date of the new version. 
103EPCA requires DOE to review its standards at 
least once every 6 years, and requires, for certain products, a 3-year period after any new standard is 
promulgated before compliance is required, except that in no case may any new standards be required within 6 years of the compliance date of the previous standards. While adding a 6-year review 
to the 3-year compliance period adds up to 9 years, DOE notes that it may undertake reviews at any time within the 6-year period and that the 3-year compliance date may yield to the 6-year backstop. 
A 9-year analysis period may not be appropriate given the variability that occurs in the timing of standards reviews and the fact that for some products, the compliance period is 5 years rather than 3 years.

OMB Circular A–4102requires 
agencies to present analytical results, 
including separate schedules of the monetized benefits and costs that show the type and timing of benefits and costs. Circular A–4 also directs agencies to consider the variability of key elements underlying the estimates of benefits and costs. For this rulemaking, DOE undertook a sensitivity analysis using 9 years, rather than 30 years, of 
product shipments. The choice of a 9- year period is a proxy for the timeline in EPCA for the review of certain energy 
conservation standards and potential revision of and compliance with such revised standards.
103The review 
timeframe established in EPCA is generally not synchronized with the product lifetime, product manufacturing cycles, or other factors specific to refrigerators, refrigerator-freezers, and freezers. Thus, such results are presented for informational purposes 
only and are not indicative of any change in DOE’s analytical methodology. The NES sensitivity 
analysis results based on a 9-year analytical period are presented in Tables V.32 and V.33. The impacts are counted over the lifetime of refrigerators, refrigerator-freezers, and freezers purchased 2027–2035 for all TSLs except TSL 4; for TSL 4, 2029– 2037 for the product classes listed in Table I.1 and 2030–2038 for the product classes listed in Table I.2.

DOE estimated the cumulative NPV of 
the total costs and savings for 
consumers that would result from the TSLs considered for refrigerators, refrigerator-freezers, and freezers. In 
accordance with OMB’s guidelines on regulatory analysis,
104DOE calculated 
NPV using both a 7-percent and a 3- percent real discount rate. Tables V.34 and V.35 show the consumer NPV results with impacts counted over the lifetime of products purchased in 2027– 2056 for all TSLs except TSL 4; for TSL 4, 2029–2058 for the product classes listed in Table I.1 and 2030–2059 for the product classes listed in Table I.2.

The previous results reflect the use of 
a default trend to estimate the change in 
price for refrigerators, refrigerator- freezers, and freezers over the analysis period (see section IV.H.3 of this 
document). DOE also conducted a sensitivity analysis that considered one scenario with a lower rate of price decline than the reference case and one scenario with a higher rate of price decline than the reference case. The results of these alternative cases are presented in appendix 10C of the direct final rule TSD. In the high-price-decline case, the NPV of consumer benefits is higher than in the default case. In the low-price-decline case, the NPV of consumer benefits is lower than in the default case. 
c. Indirect Impacts on Employment 
DOE estimates that amended energy 
conservation standards for refrigerators, 
refrigerator-freezers, and freezers will reduce energy expenditures for consumers of those products, with the resulting net savings being redirected to other forms of economic activity. These 
expected shifts in spending and economic activity could affect the demand for labor. As described in section IV.N of this document, DOE used an input/output model of the U.S. economy to estimate indirect employment impacts of the TSLs that DOE considered. There are uncertainties involved in projecting employment impacts, especially changes in the later years of the analysis. Therefore, DOE generated results for near-term timeframes (2029/30–2033/34), where 
these uncertainties are reduced. 
The results suggest that the adopted 
standards are likely to have a negligible impact on the net demand for labor in the economy. The net change in jobs is so small that it would be imperceptible in national labor statistics and might be offset by other, unanticipated effects on employment. Chapter 16 of the direct final rule TSD presents detailed results regarding anticipated indirect employment impacts. 
4. Impact on Utility or Performance of 
Products 
As discussed in section III.F.1.d of 
this document, DOE has concluded that the standards adopted in this direct final rule will not lessen the utility or performance of the refrigerators, refrigerator-freezers, and freezers under consideration in this rulemaking. Manufacturers of these products currently offer units that meet or exceed the adopted standards. 
5. Impact of Any Lessening of 
Competition 
DOE considered any lessening of 
competition that would be likely to result from new or amended standards. As discussed in section III.F.1.e, EPCA directs the Attorney General of the United States (‘‘Attorney General’’) to determine the impact, if any, of any lessening of competition likely to result from a proposed standard and to transmit such determination in writing to the Secretary within 60 days of the publication of a proposed rule, together with an analysis of the nature and extent of the impact. To assist the Attorney General in making this determination, DOE is providing DOJ with copies of this direct final rule and the TSD for review. 
6. Need of the Nation To Conserve 
Energy 
Enhanced energy efficiency, where 
economically justified, improves the Nation’s energy security, strengthens the economy, and reduces the environmental impacts (costs) of energy production. Reduced electricity demand due to energy conservation standards is also likely to reduce the cost of maintaining the reliability of the electricity system, particularly during peak-load periods. Chapter 15 in the direct final rule TSD presents the estimated impacts on electricity generating capacity, relative to the no- new-standards case, for the TSLs that DOE considered in this rulemaking. 
Energy conservation resulting from 
potential energy conservation standards for refrigerators, refrigerator-freezers, and freezers is expected to yield environmental benefits in the form of reduced emissions of certain air pollutants and greenhouse gases. Table V.38 provides DOE’s estimate of cumulative emissions reductions expected to result from the TSLs considered in this rulemaking. The emissions were calculated using the multipliers discussed in section IV.K. DOE reports annual emissions reductions for each TSL in chapter 13 of the direct final rule TSD.

As part of the analysis for this rule, 
DOE estimated monetary benefits likely

2that DOE estimated for each of the 
considered TSLs for refrigerators, refrigerator-freezers, and freezers. Section IV.L of this document discusses the estimated SC–CO

DOE is well aware that scientific and 
economic knowledge about the 
contribution of CO 2and other GHG 
emissions to changes in the future global climate and the potential resulting damages to the global and U.S. economy continues to evolve rapidly. DOE, together with other Federal agencies, will continue to review methodologies for estimating the monetary value of reductions in CO
2 
and other GHG emissions. This ongoing 
review will consider the comments on this subject that are part of the public record for this and other rulemakings, as 
well as other methodological assumptions and issues. DOE notes, 
however, that the adopted standards would be economically justified even without inclusion of monetized benefits of reduced GHG emissions. 
DOE also estimated the monetary 
value of the economic benefits associated with NO
Xand SO 2emissions 
reductions anticipated to result from the considered TSLs for refrigerators, refrigerator-freezers, and freezers. The dollar-per-ton values that DOE used are discussed in section IV.L of this 
document. Table V.42 presents the present value for NO
Xemissions 
reduction for each TSL calculated using 7-percent and 3-percent discount rates, and Table V.43 presents similar results for SO
2emissions reductions. The 
results in these tables reflect application of EPA’s low dollar-per-ton values, which DOE used to be conservative. The time-series of annual values is presented for the selected TSL in chapter 14 of the direct final rule TSD.

Not all the public health and 
environmental benefits from the 
reduction of greenhouse gases, NO X, 
and SO 2are captured in the values 
above, and additional unquantified benefits from the reductions of those pollutants as well as from the reduction of direct PM and other co-pollutants may be significant. DOE has not included monetary benefits of the reduction of Hg emissions because the amount of reduction is very small. 
7. Other Factors 
The Secretary of Energy, in 
determining whether a standard is 
economically justified, may consider any other factors that the Secretary deems to be relevant. (42 U.S.C. 6295(o)(2)(B)(i)(VII)) No other factors were considered in this analysis. 
8. Summary of Economic Impacts 
Table V.44 presents the NPV values 
that result from adding the estimates of 
the economic benefits resulting from reduced GHG and NO
Xand SO 2 
emissions to the NPV of consumer benefits calculated for each TSL considered in this rulemaking. The consumer benefits are domestic U.S. monetary savings that occur as a result of purchasing the covered refrigerators, refrigerator-freezers, and freezers, and are measured for the lifetime of products shipped in 2027–2056 for all TSLs except TSL 4; for TSL 4, 2029– 2058 for the product classes listed in Table I.1 and 2030–2059 for the product classes listed in Table I.2. 
The climate benefits associated with 
reduced GHG emissions resulting from the adopted standards are global benefits, and are also calculated based on the lifetime of refrigerators, refrigerator-freezers, and freezers shipped during the period 2027–2056 for all TSLs except TSL 4; for TSL 4, 2029–2058 for the product classes listed in Table I.1 and 2030–2059 for the product classes listed in Table I.2.

C. Conclusion 
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)) 
For this direct final rule, DOE 
considered the impacts of amended standards for refrigerators, refrigerator- freezers, and freezers at each TSL, beginning with the maximum technologically feasible 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. 
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

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 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. 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.
105 
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.
106 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. 
1. Benefits and Burdens of TSLs 
Considered for Refrigerator, Refrigerator-Freezer, and Freezer Standards 
Tables V.46 and V.47 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 I.1 and 2030– 2059 for the product classes listed in Table I.2). The energy savings, emissions reductions, and value of emissions reductions refer to full-fuel- cycle results. DOE is presenting monetized benefits of GHG emissions reductions in accordance with the applicable Executive orders and DOE would reach the same conclusion presented in this direct final rule in the absence of the social cost of greenhouse gases, including the Interim Estimates presented by the Interagency Working Group. The efficiency levels contained in each TSL are described in section V.A of this document.

Note: This table presents the costs and benefits associated with consumer refrigerators, refrigerator-freezers, and freezers shipped in 2027– 
2056 for all TSLs except TSL 4; for TSL 4, 2029–2058 for the product classes listed in Table I.1 and 2030–2059 for the product classes listed in 
Table I.2. These results include benefits to consumers which accrue after 2056 from the products shipped in 2027–2056 for all TSLs except TSL 4; for TSL 4, 2029–2058 for the product classes listed in Table I.1 and 2030–2059 for the product classes listed in Table I.2. 
* Climate benefits are calculated using four different estimates of the SC–CO
2, SC–CH 4, and SC–N 2O. Together, these represent the global 
SC–GHG. For presentational purposes of this table, the climate benefits associated with the average SC–GHG at a 3-percent discount rate are shown; however, DOE emphasizes the importance and value of considering the benefits calculated 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 IWG. 
** 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. See sec-
tion IV.L of this document for more details. 
† Total and net benefits include consumer, climate, and health benefits. For presentation purposes, total and net benefits for both the 3-percent 
and 7-percent cases are presented using the average SC–GHG with 3-percent discount rate.

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 VIPs and most would require 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 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 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. 
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 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 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 
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 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.
107 
In particular, increased incorporation 
of VIPs could increase the expense of adapting manufacturing plants. As discussed in section IV.J.2.c of this document, 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 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 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
2, 34.9 
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 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 this document, 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 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

108For 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. 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 concluded that TSL 5 is not economically justified. 
DOE then considered the 
Recommended TSL (i.e., TSL 4). For 
representative product classes other than PC 5A, PC 7, and PC 9, this TSL represents the same efficiency levels as TSL 5.
108Thus, 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 direct 
final 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. 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 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

Miscellaneous refrigeration products (88 FR 12452) utilized a 2029 compliance year for the 
NOPR analysis. 
110AHAM 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 
miscellaneous refrigeration products; www.regulations.gov/comment/EERE-2014-BT-STD- 0005-2285 (pp. 44–27) for consumer conventional 
cooking products; www.regulations.gov/comment/ EERE-2017-BT-STD-0014-0464 (pp. 40–44) for

13) for consumer clothes dryers; and www.regulations.gov/comment/EERE-2019-BT-STD- 0039-0051 (pp. 21–24) for dishwashers. 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 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 concluded they are economically justified, as discussed for the Recommended TSL in the preceding paragraphs. 
Therefore, based on the previous 
considerations, DOE adopts the energy conservation standards for refrigerators, refrigerator-freezers, and freezers at the Recommended TSL. 
While DOE considered each potential 
TSL under the criteria laid out in 42 U.S.C. 6295(o) as discussed above, DOE notes that the Recommended TSL for refrigerators, refrigerator-freezers, and freezers adopted in this direct final rule 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 this document, 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),
109the 
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.
110As 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.

standards for refrigerators, refrigerator- freezers, and freezers, which are

2. Annualized Benefits and Costs of the 
Adopted Standards 
The benefits and costs of the adopted 
standards can also be expressed in terms 
of annualized values. The annualized net benefit is (1) the annualized national economic value (expressed in 2022$) of the benefits from operating products that meet the adopted standards (consisting primarily of operating cost savings from using less energy), minus increases in product purchase costs, and (2) the annualized monetary value of the climate and health benefits. Table V.49 shows the annualized 
values for consumer refrigerator, 
refrigerator-freezers, and freezers under the Recommended TSL expressed in 2022$. 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 standards adopted in this rule 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 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 present value (in 2022$) of the costs and benefits associated with refrigerators, refrigerator-freezers, and freezers 
shipped in 2029–2058 for the product classes listed in Table I.1 and shipped in 2030–2059 for the product classes listed in Table I.2. These re-
sults include benefits which accrue after 2056 from the products shipped in 2029–2058 for the product classes listed in Table I.1 and shipped in 2030–2059 for the product classes listed in Table I.2. 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 section IV.H.3 of this docu-ment. 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 global SC–GHG ( see section IV.L of this document). For presentational 
purposes of this table, the climate benefits associated with the average SC–GHG at a 3-percent discount rate are shown; however, DOE empha-sizes the importance and value of considering the benefits calculated using all four sets of SC–GHG estimates. To monetize the benefits of re-ducing GHG emissions, this analysis uses the interim estimates presented in the Technical Support Document: Social Cost of Carbon, Methane. 
** 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 2.5pre-
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. See section IV.L of this document 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 this document. DOE’s NIA includes 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 impacts on manufacturers (the MIA). See section IV.J of this document. In the detailed MIA, DOE 
models manufacturers’ pricing decisions based on assumptions regarding investments, conversion costs, cashflow, and margins. The MIA pro-duces 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 cal-culated using the industry weighted average cost of capital value of 9.1 percent that is estimated in the manufacturer impact analysis (see chap-
ter 12 of the direct final rule TSD for a complete description of the industry weighted average cost of capital). For refrigerators, refrigerator-freez-ers, and freezers, those values are ¥$48.7 million to ¥$37.0 million. DOE accounts for that range of likely impacts in analyzing whether a TSL is economically justified. See section V.C of this document. 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 Markup 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 annualized change in INPV in the above table, drawing on the MIA explained further in section IV.J of this document, to provide additional context for as-sessing the estimated impacts of this direct final rule 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 direct final 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. Parentheses ( ) indicate negative values. 
VI. Procedural Issues and Regulatory 
Review 
A. Review Under Executive Orders 
12866, 13563, and 14094 
Executive Order (‘‘E.O.’’) 12866, 
‘‘Regulatory Planning and Review,’’ as supplemented and reaffirmed by E.O. 13563, ‘‘Improving Regulation and Regulatory Review,’’ 76 FR 3821 (Jan. 21, 2011), and amended by E.O. 14094, ‘‘Modernizing Regulatory Review,’’ 88 FR 21879 (April 11, 2023), requires agencies, to the extent permitted by law, to (1) propose or adopt a regulation only upon a reasoned determination that its benefits justify its costs (recognizing that some benefits and costs are difficult to quantify); (2) tailor regulations to impose the least burden on society, consistent with obtaining regulatory objectives, taking into account, among other things, and to the extent practicable, the costs of cumulative 
regulations; (3) select, in choosing among alternative regulatory approaches, those approaches that maximize net benefits (including potential economic, environmental, public health and safety, and other advantages; distributive impacts; and equity); (4) to the extent feasible, specify performance objectives, rather than specifying the behavior or manner of compliance that regulated entities must adopt; and (5) identify and assess available alternatives to direct regulation, including providing economic incentives to encourage the desired behavior, such as user fees or marketable permits, or providing information upon which choices can be made by the public. DOE emphasizes as well that E.O. 13563 requires agencies to use the best available techniques to quantify anticipated present and future benefits and costs as accurately as possible. In its guidance, the Office of Information and Regulatory Affairs (‘‘OIRA’’) in the Office of Management and Budget (‘‘OMB’’) has emphasized 
that such techniques may include identifying changing future compliance costs that might result from technological innovation or anticipated behavioral changes. For the reasons stated in the preamble, this final regulatory action is consistent with these principles. 
Section 6(a) of E.O. 12866 also 
requires agencies to submit ‘‘significant regulatory actions’’ to OIRA for review. OIRA has determined that this final regulatory action constitutes a 
‘‘significant regulatory action’’ within the scope of section 3(f)(1) of E.O. 12866. Accordingly, pursuant to section 6(a)(3)(C) of E.O. 12866, DOE has provided to OIRA an assessment, including the underlying analysis, of benefits and costs anticipated from the final regulatory action, together with, to the extent feasible, a quantification of those costs; and an assessment, including the underlying analysis, of costs and benefits of potentially effective and reasonably feasible alternatives to the planned regulation, and an explanation why the planned regulatory action is preferable to the identified potential alternatives. These assessments are summarized in this preamble and further detail can be found in the technical support document for this rulemaking. 
B. 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 is not obligated to prepare a 
regulatory flexibility analysis for this rulemaking because there is not a 
requirement to publish a general notice of proposed rulemaking under the Administrative Procedure Act. See 5 U.S.C. 601(2), 603(a). As discussed previously, DOE has determined that the Joint Agreement meets the necessary requirements under EPCA to issue this direct final rule for energy conservation standards for refrigerators, refrigerator- freezers, and freezers under the procedures in 42 U.S.C. 6295(p)(4). DOE notes that the NOPR for energy conservation standards for refrigerators, refrigerator-freezers, and freezers published elsewhere in the Federal Register contains an IRFA. 
C. Review Under the Paperwork Reduction Act 
Manufacturers of consumer 
refrigerators, refrigerator-freezers, and freezers must certify to DOE that their products comply with any applicable energy conservation standards. In certifying compliance, manufacturers must test their products according to the DOE test procedures for consumer refrigerators, refrigerator-freezers, and freezers, including any amendments adopted for those test procedures. DOE has established regulations for the certification and recordkeeping requirements for all covered consumer products and commercial equipment, including consumer refrigerators, refrigerator-freezers, and freezers. (See 
VerDate Sep<11>2014 19:16 Jan 16, 2024 Jkt 262001 PO 00000 Frm 00085 Fmt 4701 Sfmt 4700 E:\FR\FM\17JAR2.SGM 17JAR2lotter on DSK11XQN23PROD with RULES23110 Federal Register / Vol. 89, No. 11 / Wednesday, January 17, 2024 / Rules and Regulations 
generally 10 CFR part 429) The 
collection-of-information requirement 
for the certification and recordkeeping is subject to review and approval by OMB under the Paperwork Reduction Act (‘‘PRA’’). This requirement has been approved by OMB under OMB control number 1910–1400. Public reporting burden for the certification is estimated to average 35 hours per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. 
Notwithstanding any other provision 
of the law, no person is required to respond to, nor shall any person be subject to a penalty for failure to comply with, a collection of information subject to the requirements of the PRA, unless that collection of information displays a currently valid OMB Control Number. 
D. Review Under the National 
Environmental Policy Act of 1969 
Pursuant to the National 
Environmental Policy Act of 1969 (‘‘NEPA’’), DOE has analyzed this rule in accordance with NEPA and DOE’s NEPA implementing regulations (10 CFR part 1021). DOE has determined that this rule qualifies for categorical exclusion under 10 CFR part 1021, subpart D, appendix B, B5.1, because it is a rulemaking that establishes energy conservation standards for consumer 
products or industrial equipment, none of the exceptions identified in B5.1(b) apply, no extraordinary circumstances exist that require further environmental analysis, and it meets the requirements for application of a categorical exclusion. See 10 CFR 1021.410. 
Therefore, DOE has determined that promulgation of this rule is not a major Federal action significantly affecting the quality of the human environment within the meaning of NEPA, and does not require an environmental assessment or an environmental impact statement. 
E. Review Under Executive Order 13132 
E.O. 13132, ‘‘Federalism,’’ 64 FR 
43255 (Aug. 10, 1999), imposes certain 
requirements on Federal agencies formulating and implementing policies or regulations that preempt State law or that have federalism implications. The Executive order requires agencies to examine the constitutional and statutory authority supporting any action that would limit the policymaking discretion of the States and to carefully assess the necessity for such actions. The Executive order also requires agencies to have an accountable process to ensure meaningful and timely input by State and local officials in the development of 
regulatory policies that have federalism implications. On March 14, 2000, DOE published a statement of policy describing the intergovernmental consultation process it will follow in the development of such regulations. 65 FR 13735. 
In the February 2023 NOPR, DOE 
tentatively determined that the proposed rule would not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. 88 FR 13616. Furthermore, DOE stated that EPCA governs and prescribes Federal preemption of State regulations as to energy conservation for the products that are the subject of this proposed rule and that States can petition DOE for exemption from such preemption to the extent, and based on criteria, set forth in EPCA. Id. (citing 42 U.S.C. 6297). 
Accordingly, DOE concluded that no further action was required by E.O. 13132. 
The AGs of TN, AL, et al. submitted 
a joint comment that DOE’s analysis is woefully deficient. The AGs of TN, AL, et al. commented that this determination is incorrect because, in their view, the Proposed Standards have significant federalism implications within the meaning of Executive Order 13132. The AGs of TN, AL, et al. go on to state that if the Proposed Standards are promulgated, ‘‘[a]ny State regulation which sets forth procurement standards’’ relating to refrigerators, refrigerator-freezers, or freezers, is ‘‘superseded’’ unless those ‘‘standards are more stringent than the corresponding Federal energy conservation standards. The AGs of TN, AL, et al. argue that preempting—even in part—State procurement rules is plainly a direct effect on the States and alters the federal-state relationship by directly regulating the States. See Exec. Order No. 13132 § 6(c).’’ (The AGs of TN, AL, et al., No. 68 at p. 3) Further, the AGs of TN, et al., argue that section 6(b) of E.O. 13132 applies because states are purchasers of refrigerators, refrigerator-freezers, and freezers; therefore, reliance interests are 
implicated and subject the states to substantial direct compliance costs. (Id. at 2–3) 
DOE reiterates that this direct final 
rule does not have significant federalism implications. DOE has examined this rule and has determined that it would not have a substantial direct effect on the States, on the relationship between the National Government and the States, or on the distribution of power and 
responsibilities among the various levels of government. EPCA governs and expressly prescribes Federal preemption of State regulations as to energy conservation for the products that are the subject of this direct final rule. States can petition DOE for exemption from such preemption to the extent, and based on criteria, set forth in EPCA. (42 U.S.C. 6297) Therefore, no further action is required by Executive Order 13132. 
Even if DOE were to find otherwise, 
with regards to the AGs of TN, AL et al.’s arguments regarding section 6(c) of E.O. 13132, DOE notes that the AGs of TN, AL et al. do not provide any examples of a state procurement rule that conflicts with the standards adopted in this rulemaking and DOE is not aware of any such conflicts. While it is possible that a State may have to revise its procurement standards to reflect the new standards, States can petition DOE for exemption from such preemption to the extent, and based on criteria, set forth in EPCA. Absent such information, DOE concludes that no further action would be required by E.O. 13132 even if the Executive order were applicable here. Moreover, assuming the hypothetical preemption alleged by the AGs of TN, AL et al. were to present itself, DOE notes that, like all interested parties, states were presented with an opportunity to engage in the rulemaking process early in the development of the proposed rule. Prior to publishing the proposed rulemaking, on November 15, 2019, DOE published and sought public comment on a request for information (‘‘RFI’’) to collect data and information to help DOE determine whether any new or amended standards for consumer refrigerators, refrigerator- freezers, and freezers would result in a significant amount of additional energy savings and whether those standards would be technologically feasible and economically justified. 84 FR 62470 (‘‘November 2019 RFI’’). DOE then published a notice of public meeting and availability of the preliminary TSD on October 15, 2021, and sought public comment again. (‘‘October 2021 Preliminary Analysis’’). 86 FR 57378. DOE then held a public meeting on December 1, 2021, to discuss and receive comments on the preliminary TSD, which was open to the public, including state agencies. As such, states were provided the opportunity for meaningful and substantial input as envisioned by the Executive order. 
With regards to the AGs of TN, AL et 
al.’s arguments regarding section 6(b) of 
E.O. 13132, the potential effect alleged by the AGs of TN, AL, et al. is the same 
VerDate Sep<11>2014 19:16 Jan 16, 2024 Jkt 262001 PO 00000 Frm 00086 Fmt 4701 Sfmt 4700 E:\FR\FM\17JAR2.SGM 17JAR2lotter on DSK11XQN23PROD with RULES23111 Federal Register / Vol. 89, No. 11 / Wednesday, January 17, 2024 / Rules and Regulations 
effect experienced by all refrigerator 
consumers—models manufactured after a specific date must meet revised efficiency standards. This impact does not constitute a ‘‘substantial’’ impact as required by the Executive order. Further, contrary to the assertions of the AGs of TN et al., the direct final rule is required by law. As noted previously, where DOE determines that a proposed amended standard is designed to achieve the maximum improvement in energy efficiency and is both technologically feasible and economically justified, it must adopt it. Therefore, section 6(b) is inapplicable. E.O. 13132, section6(b) (applicable to regulation ‘‘that is not required by statute’’). 
F. Review Under Executive Order 12988 
With respect to the review of existing 
regulations and the promulgation of 
new regulations, section 3(a) of E.O. 12988, ‘‘Civil Justice Reform,’’ imposes on Federal agencies the general duty to adhere to the following requirements: (1) eliminate drafting errors and ambiguity, (2) write regulations to minimize litigation, (3) provide a clear legal standard for affected conduct rather than a general standard, and (4) promote simplification and burden reduction. 61 FR 4729 (Feb. 7, 1996). Regarding the review required by section 3(a), section 3(b) of E.O. 12988 specifically requires that Executive agencies make every reasonable effort to ensure that the regulation (1) clearly specifies the preemptive effect, if any, (2) clearly specifies any effect on existing Federal law or regulation, (3) provides a clear legal standard for affected conduct while promoting 
simplification and burden reduction, (4) specifies the retroactive effect, if any, (5) adequately defines key terms, and (6) addresses other important issues affecting clarity and general draftsmanship under any guidelines issued by the Attorney General. Section 3(c) of E.O. 12988 requires Executive agencies to review regulations in light of applicable standards in section 3(a) and section 3(b) to determine whether they are met or it is unreasonable to meet one or more of them. DOE has completed the required review and determined that, to the extent permitted by law, this direct final rule meets the relevant standards of E.O. 12988. 
G. Review Under the Unfunded 
Mandates Reform Act of 1995 
Title II of the Unfunded Mandates 
Reform Act of 1995 (‘‘UMRA’’) requires each Federal agency to assess the effects of Federal regulatory actions on State, local, and Tribal governments and the private sector. Public Law 104–4, sec. 
201 (codified at 2 U.S.C. 1531). For a regulatory action likely to result in a rule that may cause the expenditure by State, local, and Tribal governments, in the aggregate, or by the private sector of $100 million or more in any one year (adjusted annually for inflation), section 202 of UMRA requires a Federal agency to publish a written statement that estimates the resulting costs, benefits, and other effects on the national economy. (2 U.S.C. 1532(a), (b)) The UMRA also requires a Federal agency to develop an effective process to permit timely input by elected officers of State, local, and Tribal governments on a ‘‘significant intergovernmental mandate,’’ and requires an agency plan for giving notice and opportunity for timely input to potentially affected small governments before establishing any requirements that might significantly or uniquely affect them. On March 18, 1997, DOE published a statement of policy on its process for intergovernmental consultation under UMRA. 62 FR 12820. DOE’s policy statement is also available at www.energy.gov/sites/prod/files/gcprod/ documents/umra_ 97.pdf. 
DOE has concluded that this direct 
final rule may require expenditures of $100 million or more in any one year by the private sector. Such expenditures may include (1) investment in research and development and in capital expenditures by consumer refrigerators, refrigerator-freezers, and freezers manufacturers in the years between the direct final rule and the compliance date for the new standards and (2) incremental additional expenditures by consumers to purchase higher-efficiency consumer refrigerators, refrigerator- freezers, and freezers, starting at the compliance date for the applicable standard. 
Section 202 of UMRA authorizes a 
Federal agency to respond to the content requirements of UMRA in any other statement or analysis that accompanies the direct final rule. (2 U.S.C. 1532(c)) The content requirements of section 202(b) of UMRA relevant to a private sector mandate substantially overlap the economic analysis requirements that apply under section 325(o) of EPCA and Executive Order 12866. The 
SUPPLEMENTARY INFORMATION section of 
this document and the TSD for this 
direct final rule respond to those requirements. 
Under section 205 of UMRA, DOE is 
obligated to identify and consider a reasonable number of regulatory alternatives before promulgating a rule for which a written statement under section 202 is required. (2 U.S.C. 1535(a)) DOE is required to select from 
those alternatives the most cost-effective and least burdensome alternative that achieves the objectives of the rule unless DOE publishes an explanation for doing otherwise, or the selection of such an alternative is inconsistent with law. As required by 42 U.S.C. 6295(m), this direct final rule establishes amended energy conservation standards for consumer refrigerators, refrigerator- freezers, and freezers that are designed to achieve the maximum improvement in energy efficiency that DOE has determined to be both technologically feasible and economically justified, as required by sections 6295(o)(2)(A) and 6295(o)(3)(B). A full discussion of the alternatives considered by DOE is presented in chapter 17 of the TSD for this direct final rule. 
H. Review Under Executive Order 12630 
Pursuant to E.O. 12630, 
‘‘Governmental Actions and Interference 
with Constitutionally Protected Property Rights,’’ 53 FR 8859 (March 18, 1988), DOE has determined that this rule would not result in any takings that might require compensation under the Fifth Amendment to the U.S. Constitution. 
I. Review Under the Treasury and 
General Government Appropriations Act, 2001 
Section 515 of the Treasury and 
General Government Appropriations Act, 2001 (44 U.S.C. 3516, note) provides for Federal agencies to review most disseminations of information to the public under information quality guidelines established by each agency pursuant to general guidelines issued by OMB. OMB’s guidelines were published at 67 FR 8452 (Feb. 22, 2002), and DOE’s guidelines were published at 67 FR 62446 (Oct. 7, 2002). Pursuant to OMB Memorandum M–19–15, Improving Implementation of the Information Quality Act (April 24, 2019), DOE published updated guidelines which are available at www.energy.gov/sites/prod/files/2019/ 12/f70/DOE%20Final%20Updated%20IQA%20Guidelines%20Dec%202019.pdf. DOE has 
reviewed this direct final rule under the OMB and DOE guidelines and has concluded that it is consistent with applicable policies in those guidelines. 
J. Review Under Executive Order 13211 
E.O. 13211, ‘‘Actions Concerning 
Regulations That Significantly Affect 
Energy Supply, Distribution, or Use,’’ 66 FR 28355 (May 22, 2001), requires Federal agencies to prepare and submit to OIRA at OMB, a Statement of Energy 
VerDate Sep<11>2014 19:16 Jan 16, 2024 Jkt 262001 PO 00000 Frm 00087 Fmt 4701 Sfmt 4700 E:\FR\FM\17JAR2.SGM 17JAR2lotter on DSK11XQN23PROD with RULES23112 Federal Register / Vol. 89, No. 11 / Wednesday, January 17, 2024 / Rules and Regulations 
111The 2007 ‘‘Energy Conservation Standards 
Rulemaking Peer Review Report’’ is available at the following website: energy.gov/eere/buildings/ 
downloads/energy-conservation-standards- rulemaking-peer-review-report-0 (last accessed 
August 2, 2023). 
112The report is available at 
www.nationalacademies.org/our-work/review-of- methods-for-setting-building-and-equipment- performance-standards. Effects for any significant energy action. 
A ‘‘significant energy action’’ is defined as any action by an agency that promulgates or is expected to lead to promulgation of a final rule, and that (1) is a significant regulatory action under Executive Order 12866, or any successor order; and (2) is likely to have a significant adverse effect on the supply, distribution, or use of energy, or (3) is designated by the Administrator of OIRA as a significant energy action. For any significant energy action, the agency must give a detailed statement of any adverse effects on energy supply, 
distribution, or use should the proposal be implemented, and of reasonable alternatives to the action and their expected benefits on energy supply, distribution, and use. 
DOE has concluded that this 
regulatory action, which sets forth amended energy conservation standards for consumer refrigerators, refrigerator- freezers, and freezers, is not a significant energy action because the standards are not likely to have a significant adverse effect on the supply, distribution, or use of energy, nor has it been designated as such by the Administrator at OIRA. Accordingly, DOE has not prepared a Statement of Energy Effects on this direct final rule. 
K. Information Quality
On December 16, 2004, OMB, in
consultation with the Office of Science 
and Technology Policy (‘‘OSTP’’), issued its Final Information Quality Bulletin for Peer Review (‘‘the Bulletin’’). 70 FR 2664 (Jan. 14, 2005). The Bulletin establishes that certain scientific information shall be peer- reviewed by qualified specialists before it is disseminated by the Federal Government, including influential scientific information related to agency regulatory actions. The purpose of the Bulletin is to enhance the quality and credibility of the Government’s scientific information. Under the Bulletin, the energy conservation standards rulemaking analyses are ‘‘influential scientific information,’’ which the Bulletin defines as ‘‘scientific information the agency reasonably can determine will have, or does have, a clear and substantial impact on important public policies or private sector decisions.’’ 70 FR 2664, 2667. 
In response to OMB’s Bulletin, DOE 
conducted formal peer reviews of the energy conservation standards development process and the analyses that are typically used and prepared a report describing that peer review.
111 Generation of this report involved a 
rigorous, formal, and documented evaluation using objective criteria and qualified and independent reviewers to make a judgment as to the technical/ scientific/business merit, the actual or anticipated results, and the productivity and management effectiveness of programs and/or projects. Because available data, models, and technological understanding have changed since 2007, DOE has engaged with the National Academy of Sciences to review DOE’s analytical methodologies to ascertain whether modifications are needed to improve DOE’s analyses. DOE is in the process of evaluating the resulting report.
112 
L. Congressional Notification
As required by 5 U.S.C. 801, DOE will
report to Congress on the promulgation of this rule prior to its effective date. The report will state that the Office of Information and Regulatory Affairs has determined that this action meets the criteria set forth in 5 U.S.C. 804(2).
