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)(i), DOE is proposing this rule establishing and amending the energy conservation standards for consumer clothes dryers and is concurrently issuing a direct final rule published elsewhere in this issue of the Federal Register. DOE will proceed with this notice of proposed rulemaking (‘‘NOPR’’) only if it determines it must withdraw the direct final rule pursuant to the criteria provided in 42 U.S.C. 6295(p)(4). The amended standard levels in this proposed rule and the direct final rule were proposed in a letter submitted to DOE jointly by groups representing manufacturers, energy and environmental advocates, consumer groups, and a utility. This letter, titled ‘‘Energy Efficiency Agreement of 2023’’ (hereafter, the ‘‘Joint Agreement’’,
3) recommends 
specific energy conservation standards for consumer clothes dryers. DOE subsequently received letters of support for the Joint Agreement from States including New York, California, and Massachusetts
4and utilities including 
San Diego Gas and Electric and Southern California Edison
5advocating 
for the adoption of the recommended standards. As discussed in more detail in the accompanying direct final rule and in accordance with the provisions at 42 U.S.C. 6295(p)(4), DOE has determined that the recommendations contained in the Joint Agreement comply with the requirements of 42 U.S.C. 6295(o). 
In accordance with these and other 
statutory provisions discussed in this document, DOE proposes amended energy conservation standards for consumer clothes dryers. The standards are expressed in terms of the combined energy factor (‘‘CEF
D2’’), measured in 
pounds per kilowatt-hour (‘‘lb/kWh’’), as determined in accordance with DOE’s consumer clothes dryer test procedure at title 10 of the Code of Federal Regulations (‘‘CFR’’) part 430, subpart B, appendix D2 (‘‘appendix D2’’). The CEF metric includes active mode, standby mode, and off mode energy use. 
Table I.1 presents the proposed 
standards for consumer clothes dryers. The proposed standards are the same as those recommended by the Joint Agreement. These standards would apply to all products listed in Table I.1 and manufactured in, or imported into, the United States starting on March 1, 2028, as recommended in the Joint Agreement.

II. Introduction 
The following section briefly 
discusses the statutory authority underlying this proposed rule, as well as some of the relevant historical background related to the establishment of standards for consumer clothes dryers. 
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 consumer clothes dryers, the subject of this document. (42 U.S.C. 6292(a)(8)) EPCA prescribed energy conservation standards for these products (42 U.S.C. 6295(g)(3)), and directed DOE to conduct future rulemakings to determine whether to amend these standards. (42 U.S.C. 6295(g)(4)) EPCA further provides that, not later than 6 
years after the issuance of any final rule establishing or amending a standard, DOE must publish either a notice of determination that standards for the product do not need to be amended, or a NOPR including new proposed energy conservation standards (proceeding to a final rule, as appropriate). (42 U.S.C. 6295(m)(1)) 
The energy conservation program 
under EPCA consists essentially of four parts: (1) testing, (2) labeling, (3) the establishment of Federal energy conservation standards, and (4) certification and enforcement procedures. Relevant provisions of EPCA specifically include definitions (42 U.S.C. 6291), test procedures (42 U.S.C. 6293), labeling provisions (42 U.S.C. 6294), energy conservation standards (42 U.S.C. 6295), and the authority to require information and reports from manufacturers (42 U.S.C. 6296). Federal energy efficiency 
requirements for covered products 
established under EPCA generally supersede State laws and regulations concerning energy conservation testing, labeling, and standards. (42 U.S.C. 6297(a)–(c)) DOE may, however, grant waivers of Federal preemption for particular State laws or regulations, in accordance with the procedures and other provisions set forth under EPCA. (See 42 U.S.C. 6297(d)) 
Subject to certain criteria and 
conditions, DOE is required to develop test procedures to measure the energy 
efficiency, energy use, or estimated annual operating cost of each covered product. (42 U.S.C. 6295(o)(3)(A) and 42 U.S.C. 6295(r)) Manufacturers of covered products must use the prescribed DOE test procedure as the basis for certifying to DOE that their products comply with the applicable energy conservation standards adopted under EPCA and when making representations to the public regarding

the energy use or efficiency of those 
products. (42 U.S.C. 6293(c) and 42 U.S.C. 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 consumer clothes dryers appear at title 10 of the Code of Federal Regulations (‘‘CFR’’) part 430, subpart B, appendix D1 and appendix D2 (‘‘appendix D1’’ and ‘‘appendix D2,’’ respectively). 
DOE must follow specific statutory 
criteria for prescribing new or amended standards for covered products, including consumer clothes dryers. 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 (‘‘Secretary’’) determines is technologically feasible and economically justified. (42 U.S.C. 6295(o)(2)(A) Furthermore, DOE may not adopt any standard that would not result in the significant conservation of energy. (42 U.S.C. 6295(o)(3)(B)) 
Moreover, DOE may not prescribe a 
standard if DOE determines by rule that the standard is not technologically feasible or economically justified. (42 U.S.C. 6295(o)(3) (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 
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 product that has the same function or intended use if DOE determines that products within such group: (A) consume a different kind of energy from that consumed by other covered products within such type (or class); or (B) have a capacity or other performance-related feature which other products within such type (or class) do 
not have and such feature justifies a higher or lower standard. (42 U.S.C. 6295(q)(1)) In determining whether a performance-related feature justifies a different standard for a group of products, DOE considers 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 for consumer clothes dryers address standby mode and off mode energy use, as do the standards proposed in this NOPR. 
Finally, EISA 2007 amended EPCA, in 
relevant part, to grant DOE authority to directly issue a final rule (i.e., a ‘‘direct 
final rule’’) establishing an energy or water 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. 
A NOPR that proposes an identical 
energy efficiency standard must be published simultaneously with the direct final rule, and DOE must provide a public comment period of at least 110 days on this proposal. (42 U.S.C. 6295(p)(4)(A)–(B)) Based on the comments received during this period, the direct final rule will either become effective, or DOE will withdraw it not later than 120 days after its issuance if (1) one or more adverse comments is received, and (2) DOE determines that those comments, when viewed in light of the rulemaking record related to the direct final rule, may provide a reasonable basis for withdrawal of the direct final rule under 42 U.S.C. 6295(o). (42 U.S.C. 6295(p)(4)(C)) Receipt of an alternative joint recommendation may also trigger a DOE withdrawal of the direct final rule in the same manner. (Id.) After withdrawing a direct final rule, DOE must proceed with the NOPR published simultaneously with the direct final rule and publish in the Federal Register the 
reasons why the direct final rule was withdrawn. (Id.)

6DOE published a confirmation of effective date 
and compliance date for the direct final rule on 
August 24, 2011. 76 FR 52854. 
7While the current standards are based on CEF 
as determined in accordance with appendix D1, manufacturers are permitted to use the appendix D2 
test procedure to comply with the current standards, as long as they use a single appendix for 
all representations. Beginning on the compliance date of the amended standards established by this final rule, manufacturers will be required to use 
appendix D2 to comply with the amended standards. 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 42 U.S.C. 6313(a)(6)(B), as applicable. 86 FR 70892, 70912 (Dec. 13, 2021). But the 
direct final rule provision in EPCA, under which this proposed rule is issued, does not impose additional requirements applicable to other standards rulemakings, which is consistent with the unique circumstances of rules issued through 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 direct final rule published on 
April 21, 2011, (‘‘April 2011 Direct 
Final Rule’’) DOE prescribed the current energy conservation standards for consumer clothes dryers manufactured on and after January 1, 2015. 76 FR 22454.
6The current energy conservation 
standards, as amended in the 2011 Direct Final Rule, are in accordance with the appendix D1 test procedure as discussed in section II.B.2 of this document. They are based on combined energy factor (‘‘CEF’’)—a metric that incorporates energy use in active mode, standby mode, and off mode. 
The current standards are defined in 
terms of a minimum allowable CEF, as measured according to appendix D1. Even though DOE maintained the same energy efficiency descriptor for both appendix D1 and appendix D2, DOE notes that the CEF values are not equivalent because of the extensive differences in test methods.
7To avoid 
potential confusion that would result from using the same efficiency descriptor for both test procedures as it relates to the standards discussed in this document, DOE is including a ‘‘D1’’ or ‘‘D2’’ subscript when referring to the appendix D1 CEF and appendix D2 CEF, respectively (‘‘CEF
D1’’ and ‘‘CEF D2’’).

2. Current Test Procedure 
On October 8, 2021, DOE published a 
final rule for the test procedure 
rulemaking (86 FR 56608) (the ‘‘October 2021 TP Final Rule’’), in which it amended appendix D1 and appendix 
D2, both entitled ‘‘Uniform Test Method for Measuring the Energy Consumption of Clothes Dryers,’’ to provide additional detail in response to questions from manufacturers and test laboratories, including additional detail regarding the testing of ‘‘connected’’ models, dryness level selection, and the procedures for maintaining the required heat input rate for gas consumer clothes dryers; additional detail for the test procedures for performing inactive and off mode power measurements; specifications for the final moisture content (‘‘FMC’’) required for testing automatic termination control dryers; specification of a narrower scale resolution for the weighing scale used to determine moisture content of test 
loads; and specification that the test load must be weighed within 5 minutes after a test cycle has terminated. In addition, as part of the October 2021 TP Final Rule, DOE amended the test procedures to update the estimated number of annual use cycles for consumer clothes dryers; provide further direction for additional provisions within the test procedures; specify rounding requirements for all reported values; apply consistent use of nomenclature and correct typographical errors; remove obsolete sections of the test procedures, including appendix D; and update the reference to the 
applicable industry test procedure to the version certified by the American National Standards Institute (‘‘ANSI’’). 86 FR 56608, 56610. 
DOE’s current energy conservation 
standards for consumer clothes dryers are expressed in terms of CEF
D1. (See 10 
CFR 430.32(h)(3).) Appendix D1 tests timed drying cycles, and accounts for 
clothes dryers with automatic termination controls by applying a higher field use factor to units that have this feature. Appendix D2 tests ‘‘normal’’ automatic termination cycles and more accurately measure the effects of automatic cycle termination. 
EPCA authorizes DOE to design test 
procedures that measure energy efficiency, energy use, water use, or estimated annual operating cost of a covered product during a representative average use cycle or period of use. (42 U.S.C. 6293(b)(3)) The appendix D2 test procedure, which is required for use to demonstrate compliance with the amended energy conservation standards 
established in this direct final rule, measures the energy consumption of a representative use cycle that dries a load of laundry from an initial moisture content of 57.5 percent to an FMC of less than 2 percent. 86 FR 56624–56625. For timer clothes dryers, the test load is

2.5 percent of the bone-dry weight of the test load. The measured energy consumption is then normalized to determine the energy consumption required to dry the test load to 2-percent FMC, with a field use factor applied to account for the over-drying energy consumption. For automatic termination control clothes dryers, appendix D2 specifies that a ‘‘normal’’ program be selected for the test cycle, and for clothes dryers that do not have a ‘‘normal’’ program, the cycle recommended by the manufacturer for drying cotton or linen shall be selected. If the drying temperature and drying level settings can be chosen independently of the program, they shall be set at the maximum drying 
temperature setting, and at a ‘‘normal’’ or ‘‘medium’’ dryness level setting. The test is considered valid if the FMC of the test load is 2 percent or less after the completion of the test cycle. If the FMC is greater than 2 percent, the test is considered invalid and a new run shall be conducted using the highest dryness level setting. 
The current 2-percent FMC 
requirement using the DOE test cloth was adopted as representative of approximately 5-percent FMC for ‘‘real- world’’ clothing, based on data submitted in a joint petition for rulemaking.
8DOE determined in the 
final rule published on August 14, 2013, that established the appendix D2 test procedure that the specified 2-percent FMC using the DOE test load was representative of consumer expectations for dryness of clothing in field use. 78 FR 49608, 49620–49622, 49610–49611. DOE did not amend the FMC requirements in the October 2021 TP Final Rule. 86 FR 56626. 
DOE has conducted the rulemaking 
analysis for this proposed rule based on CEF
D2because compliance with the 
amended energy conservation standards established in the direct final rule published elsewhere in this issue of the Federal Register must be determined based on the use of appendix D2. DOE 
discusses additional details in section IV.C.1 of the accompanying direct final rule about how it developed the engineering baseline, in terms of CEF
D2, 
from the current consumer clothes dryer standards that are in terms of CEF
D1. 
3. The Joint Agreement 
On September 25, 2023, DOE received 
a joint statement (i.e., the Joint 
Agreement) recommending standards for consumer clothes dryers, that was submitted by groups representing manufacturers, energy and environmental advocates, consumer groups, and a utility.
9In addition to the 
recommended standards for consumer clothes dryers, the Joint Agreement also included separate recommendations for several other covered products.
10And, 
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. 
A court decision issued after DOE 
received the Joint Agreement is also relevant to today’s rule. On March 17, 2022, various States filed a petition seeking review of a final rule revoking two final rules that established product classes for residential dishwashers with a cycle time for the normal cycle of 60 
minutes or less, top-loading residential clothes washers (‘‘RCWs’’) and certain classes of consumer clothes dryers with a cycle time of less than 30 minutes, and front-loading RCWs with a cycle time of less than 45 minutes (collectively, ‘‘short cycle product classes’’). The petitioners argued that the final rule revoking the short cycle product classes violated EPCA and was arbitrary and capricious. On January 8, 2024, the United States Court of Appeals for the Fifth Circuit granted the petition for review and remanded the matter to DOE for further proceedings consistent with the Fifth Circuit’s opinion. See Louisiana v. United States Department 
of Energy, 90 F.4th 461 (5th Cir. 2024). 
On February 14, 2024, following the 
Fifth Circuit’s decision in Louisiana v. 
United States Department of Energy, DOE received a second joint statement from this same group of stakeholders in which the signatories reaffirmed the Joint Agreement, stating that the recommended standards represent the maximum levels of efficiency that are technologically feasible and economically justified.
11In the letter, 
the signatories clarified that ‘‘short- cycle’’ product classes for RCWs, consumer clothes dryers, and dishwashers did not exist at the time that the signatories submitted their recommendations and it is their understanding that these classes also do not exist at the current time. Accordingly, the parties clarified that the Joint Agreement did not address short-cycle product classes. The signatories also stated that they did not anticipate that the recommended energy conservation standards in the Joint Agreement will negatively affect

time, for consumer clothes dryers. 
In a recently issued request for 
information (‘‘RFI’’),12DOE is 
commencing a rulemaking process on remand from the Fifth Circuit (the ‘‘Remand Proceeding’’) by soliciting further information, relevant to the issues identified by the Fifth Circuit, regarding any short cycle product classes. In that Remand Proceeding, DOE will conduct the analysis required by 42 U.S.C. 6295(q)(1)(B) to determine whether any short-cycle products have a ‘‘capacity or other performance-related feature [that] . . . justifies a higher or lower standard from that which applies (or will apply) to other products. . . .’’ The Joint Agreement recommends 
amended standard levels for consumer 
clothes dryers as presented in Table II.2. (Joint Agreement, No. 55 at p. 9) Details of the Joint Agreement recommendations for other products are provided in the Joint Agreement posted in the docket.

DOE has evaluated the Joint 
Agreement and believes that it meets the 
EPCA requirements for issuance of a direct final rule. As a result, DOE published a direct final rule establishing energy conservation standards for consumer clothes dryers elsewhere in this issue of the Federal Register. If DOE receives adverse comments that may provide a reasonable basis for withdrawal and withdraws the direct final rule, DOE will consider those comments and any other comments received in determining how to proceed with this proposed rule. For further background information on these proposed standards and the supporting analyses, please see the direct final rule published elsewhere in this issue of the Federal Register. That document and the accompanying technical support document (‘‘TSD’’) contain an in-depth discussion of the analyses conducted in evaluating the Joint Agreement, the methodologies DOE used in conducting those analyses, and the analytical results. 
When the Joint Agreement was 
submitted, DOE was conducting a rulemaking to consider amending the standards for consumer clothes dryers. As part of that process, DOE published a NOPR and announced a public webinar to respond to initial comments on August 23, 2022 (‘‘August 2022 NOPR’’) seeking comment on its proposed amended standards to inform its decision consistent with its obligations under EPCA and the Administrative Procedures Act (‘‘APA’’). 87 FR 51734. DOE subsequently held a public webinar on September 13, 2022, to discuss and receive comments on the August 2022 NOPR TSD. The August 2022 NOPR TSD is available at: www.regulations.gov/document/EERE- 2014-BT-STD-0058-0034. 
III. Proposed Standards 
When considering new or amended 
energy conservation standards, the 
standards that DOE adopts for any type (or class) of covered product must be designed to achieve the maximum improvement in energy efficiency that the Secretary determines is technologically feasible and economically justified. (42 U.S.C. 6295(o)(2)(A)) In determining whether a standard is economically justified, the Secretary must determine whether the benefits of the standard exceed its burdens by, to the greatest extent practicable, considering the seven statutory factors discussed previously. (42 U.S.C. 6295(o)(2)(B)(i)) The new or amended standard must also result in significant conservation of energy. (42 U.S.C. 6295(o)(3)(B)) 
DOE considered the impacts of 
amended standards for consumer clothes dryers at each trial standard level (‘‘TSL’’), beginning with the maximum technologically feasible (‘‘max-tech’’) level, to determine whether that level was economically justified. Where the max-tech level was not justified, DOE then considered the next most efficient level and undertook the same evaluation until it reached the highest efficiency level that is both technologically feasible and economically justified and saves a significant amount of energy. DOE refers to this process as the ‘‘walk-down’’ analysis. 
To aid the reader as DOE discusses 
the benefits and/or burdens of each TSL, tables in this section present a summary of the results of DOE’s quantitative analysis for each TSL. In addition to the quantitative results presented in the tables, DOE also considers other burdens and benefits that affect economic justification. These include the impacts on identifiable subgroups of consumers who may be disproportionately affected by a national standard and impacts on employment. 
DOE also notes that the economics 
literature provides a wide-ranging discussion of how consumers trade off upfront costs and energy savings in the absence of government intervention. Much of this literature attempts to explain why consumers appear to undervalue energy efficiency improvements. There is evidence that consumers undervalue future energy savings as a result of (1) a lack of information; (2) a lack of sufficient salience of the long-term or aggregate benefits; (3) a lack of sufficient savings to warrant delaying or altering purchases; (4) excessive focus on the short term, in the form of inconsistent weighting of future energy cost savings relative to available returns on other investments; (5) computational or other difficulties associated with the evaluation of relevant tradeoffs; and (6) a divergence in incentives (for example,

Studies. 2005. 72(3): pp. 853–883. doi: 10.1111/

and purchasers). Having less than perfect foresight and a high degree of uncertainty about the future, consumers may trade off these types of investments at a higher than expected rate between current consumption and uncertain future energy cost savings. 
In DOE’s current regulatory analysis, 
potential changes in the benefits and costs of a regulation due to changes in 
consumer purchase decisions are included in two ways. First, if consumers forego the purchase of a product in the standards case, this decreases sales for product manufacturers, and the impact on manufacturers attributed to lost revenue is included in the manufacturer impact analysis (‘‘MIA’’). Second, DOE accounts for energy savings attributable only to products actually used by consumers in the standards case; if a standard decreases the number of products purchased by consumers, this 
decreases the potential energy savings from an energy conservation standard. DOE provides estimates of shipments and changes in the volume of product purchases in chapter 9 of the direct final rule TSD
14available in the docket for 
this rulemaking. However, DOE’s current analysis does not explicitly control for heterogeneity in consumer preferences, preferences across subcategories of products or specific features, or consumer price sensitivity variation according to household income.

A. Benefits and Burdens of TSLs Considered for Consumer Clothes Dryers Standards 
Table III.1 and Table III.2 summarize 
the quantitative impacts estimated for 
each TSL for consumer clothes dryers. The national impacts are measured over the lifetime of consumer clothes dryers purchased in the 30-year period that begins in the anticipated year of 
compliance with amended standards (2027–2056).
16The energy savings, 
emissions reductions, and value of emissions reductions refer to full-fuel- cycle (‘‘FFC’’) results. The efficiency levels contained in each TSL are described in section V.A of the direct final rule published elsewhere in this issue of the Federal Register. DOE is presenting monetized benefits of greenhouse gas (‘‘GHG’’) emissions reductions in accordance with the applicable Executive Orders and DOE would reach the same conclusion presented in this notice 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 the direct final rule published elsewhere in this issue of the Federal Register.

Note: This table presents the costs and benefits associated with consumer clothes dryers shipped during the period 2027–2056 for all TSLs 
except TSL 3 (the Recommended TSL) and 2028–2057 for TSL 3. These results include consumer, climate, and health benefits that accrue after 
2056 from the products shipped during the period 2027–2056 for all TSLs except TSL 3 and 2057 from the products shipped during the period 2028–2057 for TSL 3. 
* Climate benefits are calculated using four different estimates of the four different estimates of the social cost of carbon (S C–CO
2), methane 
(SC–CH 4), and nitrous oxide (SC–N 2O) (model average at 2.5-percent, 3-percent, and 5-percent discount rates; 95th percentile at 3-percent dis-
count rate). Together, these represent the global SC–GHG. For presentational purposes of this table, the climate benefits associated with the av-erage SC–GHG at a 3-percent discount rate are shown; however, DOE emphasizes the importance and value of considering the benefits cal-culated using all four sets of SC–GHG estimates. To monetize the benefits of reducing GHG emissions, this analysis uses the interim estimates presented in the Technical Support Document: Social Cost of Carbon, Methane, and Nitrous Oxide Interim Estimates Under Executive Order 13990 published in February 2021 by the Interagency Working Group (‘‘IWG’’) on the Social Cost of Greenhouse Gases. See 
www.whitehouse.gov/wp-content/uploads/2021/02/TechnicalSupportDocumentSocialCostofCarbonMethaneNitrousOxide.pdf. 
** Health benefits are calculated using benefit-per-ton values for NO
Xand SO 2. DOE is currently only monetizing (for NO Xand SO 2) PM 2.5pre-
cursor health benefits and (for NO X) ozone precursor health benefits, but will continue to assess the ability to monetize other effects such as 
health benefits from reductions in direct PM 2.5emissions. The health benefits are presented at real discount rates of 3 and 7 percent. For more 
details, see section IV.L of the direct final rule published elsewhere in this issue of the F EDERAL REGISTER . 
† 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.

DOE first considered TSL 6, which 
represents the max-tech efficiency level 
and includes the design parameters of the most efficient products available on the market or in working prototypes for all product classes. The max-tech design options include heat pump technology for electric consumer clothes dryers and inlet air preheat technology for gas consumer clothes dryers. DOE’s shipments analysis estimates approximately 1 percent of annual consumer clothes dryer shipments currently meet this level. TSL 6 would save an estimated 9.76 quadrillion 
British thermal units (‘‘quads’’) of energy, an amount DOE considers significant. Under TSL 6, the net present value (‘‘NPV’’) of consumer benefit would be $8.6 billion using a discount

rate of 7 percent, and $30.5 billion using 
a discount rate of 3 percent. 
The cumulative emissions reductions 
at TSL 6 would be 189.6 million tons (‘‘Mt’’) of CO
2, 53.6 thousand tons of 
SO 2, 366.0 thousand tons of NO X, 0.4 
ton of Hg, 1,654 thousand tons of CH 4, 
and 1.7 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 would be $10.9 billion. The estimated monetary value of the health benefits from reduced SO
2and NO Xemissions at 
TSL 6 would be $8.7 billion using a 7- percent discount rate and $20.9 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 would be $28.2 billion. Using a 3-percent discount rate for all benefits and costs, the estimated total NPV at TSL 6 would be $62.2 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, the average life-cycle cost 
(‘‘LCC’’) impact on affected consumers would be a savings of $41 for electric standard, ¥$209 for electric compact 
(120V), ¥$230 for vented electric 
compact (240V), $13 for vented gas standard, ¥$102 for ventless electric 
compact (240V), and ¥$531 for ventless electric combination washer-dryer. The simple payback period (‘‘PBP’’) would be 6 years for electric standard, 18 years for electric compact (120V), 20 years for vented electric compact (240V), 5 years for vented gas standard, 11 years for ventless electric compact (240V), and 46 years for ventless electric combination washer-dryer. The fraction of consumers experiencing a net LCC cost would be 
63 percent for electric standard, 91 percent for electric compact (120V), 93 percent for vented electric compact (240V), 69 percent for vented gas standard, 59 percent for ventless electric compact (240V), and 95 percent for ventless electric combination washer- dryer. Overall, across the product classes, the majority of consumers would experience a net LCC cost, especially for senior households. DOE estimated that more 72 percent of senior-only households would experience a net LCC cost at TSL 6. 
At TSL 6, the projected change in 
industry net present value (‘‘INPV’’) ranges from a decrease of $1,511.1 million to a decrease of $361.9 million, 
corresponding to decreases of 71.4 percent and 17.1 percent, respectively. The loss in INPV is largely driven by industry conversion costs as manufacturers work to redesign their portfolios of model offerings and retool entire factories to comply with amended standards at this level. Industry conversion costs could reach $1,516.9 million at this TSL. 
Conversion costs at TSL 6 are 
significant as nearly all existing consumer clothes dryer models would need to be redesigned to meet the max- tech efficiencies. Approximately 1 percent of industry shipments currently meet TSL 6. For the electric clothes dryer product classes, manufacturers would need to implement heat pump technology to meet max-tech levels. Out of the 19 original equipment manufacturers (‘‘OEMs’’) that manufacture electric consumer clothes dryers, nine OEMs offer heat pump models for the U.S. market. The remaining 10 OEMs do not offer any models for the domestic market that utilize heat pump technology. A standard that could only be met using heat pump technology would require a total renovation of existing production facilities and would require most manufacturers to design completely new clothes dryer platforms, as they would not be able to maintain the resistive heating designs that currently dominate the U.S. electric clothes dryer market. In interviews, several manufacturers expressed concern about a potential shortage of products given the required scale of investment, redesign efforts, and 3-year compliance timeline. 
For gas consumer clothes dryers, 
manufacturers would need to implement inlet air preheat technology along with other design options to meet the efficiency levels required by TSL 6. Thus far, consumer clothes dryers with this technology and performance have not been observed in consumer clothes dryers available on the consumer market. Consumer clothes dryers with inlet air preheat designs have been observed only in laboratory settings. In interviews, some manufacturers raised concerns about implementing a relatively untested technology for the consumer market. There is very little 
industry experience with inlet air preheat designs. Several manufacturers speculated that implementing inlet air preheat technology would require a major overhaul of existing production facilities and a significant amount of engineering time. 
At this level, DOE estimates an 11- 
percent drop in shipments in the year the standard would take effect compared to the no-new-standards case, 
as price-sensitive consumers may forgo purchasing a new clothes dryer or rely on alternatives such as repair or purchasing a used dryer due to the increased upfront cost of baseline models. 
The Secretary tentatively concludes 
that at TSL 6 for consumer clothes dryers, 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, especially senior-only households, as well as the impacts on manufacturers, including the potential for large conversion costs and reduction in INPV. 
TSL 6, representing the most efficient 
heat pump technology on the market, would provide significant energy savings potential, as discussed. Despite the current and potential future benefits of heat pump technology, the analysis at TSL 6 indicates that a significant fraction of consumers of electric and vented gas standard clothes dryers, including low-income and senior-only households, would experience a net cost given the current relatively high incremental cost of electric and vented gas standard clothes dryers at the max- tech efficiency level. This is particularly pronounced for electric standard clothes dryers, where the incremental production cost at the max-tech efficiency level is comparable to the manufacturer production cost for the baseline efficiency level. Consumers with existing electric standard clothes dryers below EL 4 (about 55 percent) and consumers with existing vented gas standard clothes dryers below EL 3 (about 50 percent) would be more likely to experience a net cost at TSL 6, given the relatively modest decrease in operating costs compared to the high incremental installed costs. Few products currently meet the efficiency levels required by TSL 6. DOE estimates that approximately 1 percent of current shipments meet the max-tech efficiencies. At max-tech, limited industry experience by certain manufacturers with the high-efficiency design options, the large conversion costs to update facilities and product designs, and expected drop in industry 
shipments would result in a reduction of INPV and a potential shortage of products given the required scale of investment, redesign efforts, and time constraints. Consequently, the Secretary has tentatively concluded that TSL 6 is not economically justified. 
DOE then considered TSL 5, which 
represents the maximum energy savings with positive NPV. TSL 5 corresponds

to the max-tech level (EL 7), which 
represents heat pump technology, for the electric standard product class, and the efficiency levels corresponding to modulating (2-stage) heating technology in the electric compact (120V) and inlet air preheat technology in the vented electric compact (240V) product classes considered in this analysis. For the vented gas standard product class, TSL 5 corresponds to the max-tech level (EL 4), which represents inlet air preheat technology. TSL 5 would save an estimated 9.70 quads of energy, an amount DOE considers significant. Under TSL 5, the NPV of consumer benefit would be $9.0 billion using a discount rate of 7 percent, and $31.2 billion using a discount rate of 3 percent. 
The cumulative emissions reductions 
at TSL 5 would be 188.6 Mt of CO
2, 53.3 
thousand tons of SO 2, 364.1 thousand 
tons of NO X, 0.4 ton of Hg, 1,646 
thousand tons of CH 4, and 1.7 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 would be $10.8 billion. The estimated monetary value of the health benefits from reduced SO
2 
and NO Xemissions at TSL 5 would be 
$ 8.7 billion using a 7-percent discount rate and $20.8 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 would be $28.5 billion. Using a 3-percent discount rate for all benefits and costs, the estimated total NPV at TSL 5 would be $62.8 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, the average LCC impact on 
affected consumers would be a savings of $41 for electric standard, $66 for electric compact (120V), $22 for vented electric compact (240V), $13 for vented gas standard, $99 for ventless electric compact (240V), and $10 for ventless electric combination washer-dryer. The 
simple PBP would be 6 years for electric standard, 2 years for electric compact (120V), 7 years for vented electric compact (240V), 5 years for vented gas standard, 0.4 years for ventless electric compact (240V), and zero years for ventless electric combination washer- dryer. The fraction of consumers experiencing a net LCC cost would be 63 percent for electric standard, 22 
percent for electric compact (120V), 61 percent for vented electric compact (240V), 69 percent for vented gas standard, and zero percent for ventless electric compact (240V) and ventless electric combination washer-dryer. Overall, across the product classes, approximately 63 percent of consumers would experience a net LCC cost, especially for senior-only households. DOE estimated that more than 71 percent of senior-only households would experience a net LCC cost at TSL 5. 
At TSL 5, the projected change in 
INPV ranges from a decrease of $1,435.5 million to a decrease of $314.6 million, corresponding to decreases of 67.9 percent and 14.9 percent, respectively. Industry conversion costs could reach $1,436.9 million at this TSL. 
DOE’s shipments analysis estimates 
approximately 2 percent of annual shipments currently meet this level. At TSL 5, the efficiency levels and analyzed design options for electric standard and vented gas standard dryers (which together account for approximately 98 percent of industry shipments) are the same as at max-tech. Thus, requiring heat pump technology for electric standard dryers and inlet air preheat for vented gas standard dryers would result in similar conversion costs, reduction in INPV, and drop in shipments as TSL 6. 
At this level, DOE estimates an 11- 
percent drop in shipments in the year the standard would take effect compared to the no-new-standards case, as price-sensitive consumers may forgo purchasing a new clothes dryer or rely on alternatives such as repair or purchasing a used dryer due to the increased upfront cost of baseline models. 
The Secretary tentatively concludes 
that at TSL 5 for consumer clothes dryers, 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, especially senior-only households, as well as the impacts on manufacturers, including the significant conversion costs and large potential reduction in INPV. A significant fraction of electric standard clothes dryer consumers, including low-income and senior-only households, would experience a net cost. This is due to the high incremental cost of electric standard clothes dryers at the max-tech efficiency level. Consumers with existing electric standard clothes dryers below EL 4 would be more likely to experience a net cost at TSL 5, given the relatively 
modest decrease in operating costs compared to the high incremental installed costs. DOE estimates that approximately 2 percent of shipments currently meet the efficiencies required by this TSL. At TSL 5, the limited industry experience by certain manufacturers with the high-efficiency design options, the large conversion costs to update facilities and product designs, and expected drop in industry shipments would result in a reduction of INPV and a potential shortage of products given the required scale of investment, redesign efforts, and time constraints. Consequently, the Secretary has tentatively concluded that TSL 5 is not economically justified. 
DOE then considered TSL 4, which 
represents the maximum national energy savings with simple PBP less than 4 years for each product class. TSL 4 corresponds to the EL that represents inlet air preheat technology for the electric standard product class considered in this analysis. For the electric compact (120V) and vented electric compact (240V) product classes, TSL 4 corresponds to EL 4, which represents modulating (2-stage) heating technology. For the vented gas standard product class, TSL 4 corresponds to EL 3, which also represents modulating (2- stage) heating technology. TSL 4 would save an estimated 3.52 quads of energy, an amount DOE considers significant. Under TSL 4, the NPV of consumer benefit would be $8.4 billion using a discount rate of 7 percent, and $19.9 billion using a discount rate of 3 percent. 
The cumulative emissions reductions 
at TSL 4 would be 73.5 Mt of CO
2, 19.0 
thousand tons of SO 2, 146.7 thousand 
tons of NO X, 0.1 ton of Hg, 661.6 
thousand tons of CH 4, and 0.6 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 4 would be $4.3 billion. The estimated monetary value of the health benefits from reduced SO
2 
and NO Xemissions at TSL 4 would be 
$3.6 billion using a 7-percent discount rate and $8.2 million 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 4 would be $16.3 billion. Using a 3-percent discount rate for all benefits and costs, the estimated total NPV at TSL 4 would be $32.4 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 4, the average LCC impact on 
affected consumers would be a savings of $101 for electric standard, $66 for electric compact (120V), $90 for vented electric compact (240V), $102 for vented gas standard, $99 for ventless electric compact, and $10 for ventless electric combination washer-dryer. The simple PBP would be 2 years for electric standard, 2 years for electric compact (120V), 2 years for vented electric compact (240V), 2 years for vented gas standard, 0.4 years for ventless electric compact (240V), and zero years for ventless electric combination washer- dryer. The fraction of consumers experiencing a net LCC cost would be 48 percent for electric standard, 22 percent for electric compact (120V), 13 percent for vented electric compact (240V), 7 percent for vented gas standard, and zero percent for ventless electric compact (240V) and ventless electric combination washer-dryer. Overall, across the product classes, approximately 40 percent of consumers would experience a net LCC cost, especially for senior households. DOE estimated that about 45 percent of senior-only households would experience a net LCC cost at TSL 4. 
At TSL 4, the projected change in 
INPV ranges from a decrease of $613.5 million to a decrease of $390.6 million, corresponding to decreases of 29.0 percent and 18.5 percent, respectively. Industry conversion costs could reach $667.5 million at this TSL. 
At TSL 4, the majority of consumer 
clothes dryer models would need to be redesigned to meet the efficiency levels required. DOE’s shipments analysis estimates approximately 15 percent of current shipments meet this level. For electric standard dryers, the design options include implementing inlet air preheat and other features. As previously noted, electric standard dryers account for approximately 81 percent of total shipments. At the current time, there is very little industry experience with inlet air preheat designs. Currently, DOE is not aware of any consumer clothes dryers on the market utilizing this design option. 
DOE’s shipments analysis estimates that approximately 7 percent of electric standard shipments currently meet the efficiency required by TSL 4. Implementing inlet air preheat for electric standard dryers would represent a major overhaul of existing product lines and manufacturing facilities. This change would necessitate significant investments in new equipment and 
tooling. Product conversion costs would be necessary for designing, prototyping, and testing new or updated platforms. 
For vented gas standard clothes 
dryers, the analyzed design option at TSL 4 includes modulating (2-stage) heat technology, among other design options. Out of the nine OEMs that manufacture vented gas standard clothes dryers, eight offer products that meet the efficiencies required at TSL 4. DOE does not believe that there are any substantive barriers to modulating (2- stage) heating technology. Capital conversion costs would be necessary as manufacturers increase tooling for 2- stage heating systems. Product conversion costs would be necessary for cost-optimizing and testing new designs for a market with potential amended standards. 
At this level, DOE does not expect a 
notable drop in shipments in the year the standard takes effect. 
The Secretary tentatively concludes 
that at TSL 4 for consumer clothes dryers, 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, especially senior-only households, as well as the impacts on manufacturers, including the conversion costs and profit margin impacts that could result in a large reduction in INPV. A significant fraction of electric standard clothes dryer consumers, including senior-only households, would experience a net cost. This is due to the high incremental cost of electric standard clothes dryers at the inlet air preheat technology efficiency level. Consumers with existing electric standard clothes dryers below EL 4 would be more likely to experience a net cost at TSL 4, given the relatively modest decrease in operating costs compared to the high incremental installed costs. For electric standard 
dryers, DOE estimates that approximately 7 percent of shipments currently meet the efficiency level required by this TSL. At TSL 4, the limited industry experience of electric standard dryer manufacturers with inlet air preheat technology and the large conversion costs to update facilities and product designs, would result in a large reduction of INPV. Consequently, the Secretary has tentatively concluded that TSL 4 is not economically justified. 
DOE then considered TSL 3, which 
corresponds to the TSL recommended in the Joint Agreement (the ‘‘Recommended TSL’’) and, which also represents a set of intermediate efficiency levels between those 
designated in TSL 2 and TSL 4 and corresponds to the current ENERGY STAR efficiency levels for the electric standard and vented gas standard product classes, which represent approximately 98 percent of the market. The Recommended TSL corresponds to the EL that represents modulating (2- stage) heating technology for the electric standard and electric compact (120V) product classes. For the vented gas standard product class, the Recommended TSL corresponds to EL 3, which also represents modulating (2- stage) heating technology. For the vented gas compact product class, the Recommended TSL corresponds to baseline CEF
D2. For the electric compact 
(240V) product classes, the Recommended TSL corresponds to EL 2 for vented consumer clothes dryers, which represents a model with an optimized heating system and EL 1 for ventless consumer clothes dryers, which represents a baseline model with a more advanced automatic termination control system. For the ventless electric combination washer-dryer product class, the Recommended TSL corresponds to EL 1, which represents a baseline model with high-speed spin technology. The Recommended TSL would save an estimated 2.66 quads of energy, an amount DOE considers significant. Under the Recommended TSL, the NPV of consumer benefit would be $9.23 billion using a discount rate of 7 percent, and $20.08 billion using a discount rate of 3 percent. 
The cumulative emissions reductions 
at the Recommended TSL would be 57.1 Mt of CO
2, 13.9 thousand tons of SO 2, 
116.5 thousand tons of NO X, 0.1 ton of 
Hg, 527.6 thousand tons of CH 4, and 0.5 
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 3 would be $3.3 billion. The estimated monetary value of the health benefits from reduced SO
2and NO Xemissions at 
TSL 3 would be $2.6 billion using a 7- percent discount rate and $6.3 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 would be $15.2 billion. Using a 3- percent discount rate for all benefits and costs, the estimated total NPV at the Recommended TSL would be $29.7 
billion. The estimated total NPV is provided for additional information;

0058-0058. however, DOE primarily relies upon the 
NPV of consumer benefits when determining whether a standard level is economically justified. 
At the Recommended TSL, the 
average LCC impact on affected consumers would be a savings of $252 for electric standard, $66 for electric compact (120V), $90 for vented electric compact (240V), $102 for vented gas standard, $99 for ventless electric compact, and $11 for ventless electric combination washer-dryer. The simple PBP would be 1 year for the largest product class (electric standard), 2 years for electric compact (120V), 2 years for vented electric compact (240V), 2 years for vented gas standard, 0.4 years for ventless electric compact (240V), and zero years for ventless electric combination washer-dryer. The fraction of consumers experiencing a net LCC cost would be 1 percent for electric standard, 21 percent for electric compact (120V), 12 percent for vented electric compact (240V), 7 percent for vented gas standard, and zero percent for ventless electric compact (240V) and ventless electric combination washer- dryer. Overall, across the product classes, approximately 2 percent of consumers, including low-income and senior-only households, would experience a net LCC cost. 
At the Recommended TSL, the 
projected change in INPV ranges from a decrease of $144.2 million to a decrease of $119.7 million, corresponding to decreases of 6.8 percent and 5.7 percent, respectively. Industry conversion costs could reach $180.7 million at this TSL. 
DOE expects that some existing 
consumer clothes dryer models would need to be redesigned to meet the Recommended TSL efficiencies, but there are a wide range of available models for vented electric standard dryers due to participation in the ENERGY STAR program. DOE’s shipments analysis estimates approximately 48 percent of annual shipments currently meet this level. For electric standard, electric compact (120V), vented electric compact (240V), and vented gas standard clothes dryers, which account for approximately 99 percent of total annual shipments, the design options include implementing electronic controls, optimized heating systems, more advanced automatic 
termination controls, and modulating (2-stage) heat. Of the 19 electric dryer OEMs, 14 offer products at or above the efficiencies required for the electric dryer product classes at the Recommended TSL. Out of the nine OEMs that manufacture vented gas standard clothes dryers, eight offer products that meet the efficiencies required at the Recommended TSL. 
Capital conversion costs may be necessary as manufacturers increase tooling for 2-stage heating systems. Manufacturers may choose to further cost-optimize and test new designs as a result of the standards, but DOE believes some of this has already occurred in response to ENERGY STAR. DOE does not expect any drop in shipments in the year the standard takes effect. 
For all TSLs considered in this 
NOPR—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 March 1, 2028, compliance date specified in the Joint Agreement as it was an integral part of the multi- product joint recommendation. A 2028 compliance year would provide manufacturers additional flexibility to spread capital requirements, engineering resources, and conversion activities over a longer period of time depending on the individual needs of each manufacturer. 
At the Recommended TSL, DOE’s 
data demonstrate no negative impact on consumer utility for consumer clothes dryers. In addition, the second joint statement from the same group of stakeholders that submitted the Joint Agreement states that DOE’s test data show, and industry experience agrees, that the recommended standard level for consumer clothes dryers will not result in significant differences in cycle time and will adequately dry clothes.
17Based 
on the information available, DOE concludes that no lessening of product utility or performance would occur at the Recommended TSL. 
After considering the analysis and 
weighing the benefits and burdens, the Secretary has tentatively concluded that a standard set at the Recommended TSL for consumer clothes dryers would result in the maximum improvement in energy efficiency that is technologically feasible and economically justified and also result in the significant conservation of energy. At this TSL, the average LCC savings for all consumer clothes dryer product classes would be positive. An estimated weighted average of 2 percent of consumer clothes dryer consumers would experience a net cost. The FFC national energy savings would be significant and the NPV of consumer benefits would be positive using both a 3-percent and 7-percent discount rate. Notably, the benefits to consumers 
would 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, would be over 64 times higher than the maximum estimated manufacturers’ loss in INPV. The positive LCC savings—a different way of quantifying consumer benefits— reinforces this conclusion. 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 $3.3 billion in climate benefits (associated with the average SC–GHG at a 3-percent discount rate), and $6.3 billion (using a 3-percent discount rate) or $2.6 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. The walk-down is not a comparative analysis, as a comparative analysis would result in the maximization of net benefits instead of energy savings that are technologically feasible and economically justified, which would be contrary to the statute. 86 FR 70892, 70908. Although DOE has not conducted a comparative analysis to select the proposed amended energy conservation standards, DOE notes that as compared to TSL 6, TSL 5, and TSL 4, the Recommended TSL would have higher average LCC savings, smaller percentages of consumers experiencing a net cost, a lower maximum decrease in INPV, and lower manufacturer conversion costs. 
Although DOE considered amended 
standard levels for consumer clothes dryers by grouping the efficiency levels for each product class into TSLs, DOE evaluates all analyzed efficiency levels in its analysis. Accordingly, the Secretary has tentatively concluded that the Recommended TSL would offer the maximum improvement in efficiency that is technologically feasible and economically justified and would result in the significant conservation of energy. For electric standard and vented gas standard consumer clothes dryers, which account for approximately 98 percent of U.S. shipments, requiring efficiency levels above the levels required by the Recommended TSL would result in a large percentage of 
consumers experiencing a net LCC cost, in addition to significant manufacturer

Miscellaneous refrigeration products (88 FR 12452) utilized a 2029 compliance year for the NOPR analysis. impacts and reductions in INPV. 
Additionally, for consumer clothes dryers, most manufacturers offer products that can meet the Recommended TSL across both electric and gas consumer clothes dryers. In addition, the Recommended TSL corresponds to the current ENERGY STAR levels for electric standard and vented gas standard clothes dryers, which have significant market share and manufacturer support due to their promotion over the past couple of years as a voluntary energy efficiency program. The adoption of standards, if finalized, at this TSL may encourage ENERGY STAR to further consider more efficient levels for dryers in the year leadings up to the compliance of date of the standard, which would in turn likely spur additional market introductions of consumer clothes dryers with heat pump technology, foster maturation of the technology and downward price trends, and further support differentiation within the dryer market for energy efficient products. For electric and vented gas standard consumer clothes dryers, the Recommended TSL is comprised of EL 4 and EL 3, respectively, resulting in 
higher LCC savings, a significant reduction in the number of consumers experiencing a net cost, a lower maximum decrease in INPV, and lower 
conversion costs to the point where DOE has tentatively concluded they are economically justified, as discussed for the Recommended TSL in the preceding paragraphs. 
Therefore, based on the previous 
considerations, DOE proposes the energy conservation standards for consumer clothes dryers at the Recommended TSL. 
While DOE considered each potential 
TSL under the criteria laid out in 42 U.S.C. 6295(o) as discussed in the preceding paragraphs, the Recommended TSL for consumer clothes dryers proposed in this NOPR is 
part of a multi-product Joint Agreement covering six rulemakings (residential clothes washers; consumer clothes dryers; consumer conventional cooking products; dishwashers; refrigerators, refrigerator-freezers, and freezers; and miscellaneous refrigeration products). The signatories indicate that the Joint Agreement for the six rulemakings should be considered as a joint statement of recommended standards, to be adopted in its entirety. As discussed in section V.B.2.e of the direct final rule published elsewhere in this issue of the Federal Register, many consumer clothes dryer OEMs also manufacture residential clothes washers; consumer conventional cooking products; 
dishwashers; refrigerators, refrigerator- freezers, and freezers; and miscellaneous refrigeration products. Therefore, there are potential integrated benefits to the Joint Agreement. Rather than requiring compliance with five amended standards in a single year 
(2027),
18the negotiated multi-product 
Joint Agreement staggers the compliance dates for the five amended standards over a 4-year period (2027–2030). DOE understands that the compliance dates recommended in the Joint Agreement would help reduce cumulative regulatory burden by allowing greater flexibility in the allocation of resources to comply with multiple concurrent amended standards and by aligning compliance dates for products that are typically designed or sold as matched pairs (i.e., clothes washers and clothes 
dryers). The Joint Agreement also provides additional years of regulatory certainty for manufacturers and their suppliers while still achieving the maximum improvement in energy efficiency that is technologically feasible and economically justified. 
The proposed amended energy 
conservation standards for consumer clothes dryers, which are expressed as CEF
D2, are shown in Table III.3.

B. Annualized Benefits and Costs of the 
Proposed Standards 
The benefits and costs of the proposed 
standards can also be expressed in terms of annualized values. The annualized net benefit is (1) the annualized national economic value (expressed in 2022$) of the benefits from operating products that meet the proposed standards (consisting primarily of operating cost savings from using less energy, minus increases in product purchase costs, and (2) the annualized monetary value of the climate and health benefits from emission reductions. Table II.4 shows the annualized 
values for consumer clothes dryers 
under the Recommended TSL, expressed in 2022$. The results under the primary estimate are as follows. 
Using a 7-percent discount rate for 
consumer benefits and costs and NO
X 
and SO 2reductions, and the 3-percent 
discount rate case for GHG social costs, the estimated cost of the proposed standards for consumer clothes dryers 
would be $60.0 million per year in increased equipment installed costs, while the estimated annual benefits would be $971.4 million from reduced equipment operating costs, $185.5 million in GHG reductions, and $259.9 million from reduced NO
Xand SO 2 
emissions. In this case, the net benefit 
would amount to $1,357 million per year. 
Using a 3-percent discount rate for all 
benefits and costs, the estimated cost of the proposed standards for consumer clothes dryers would be $57.2 million per year in increased equipment costs, while the estimated annual benefits would be $1,177 million in reduced 
operating costs, $185.5 million from GHG reductions, and $349.4 million from reduced NO
Xand SO 2emissions. 
In this case, the net benefit would amount to $1,654 million per year.

Note: This table presents the costs and benefits associated with consumer clothes dryers shipped during the period 2028–2057. These r esults 
include benefits to consumers which accrue after 2057 from the products shipped during the period 2028–2057. The Primary, Low-N et-Benefits, 
and High-Net-Benefits estimates utilize projections of energy prices from the AEO2023 Reference case, Low Economic Growth case, and High 
Economic Growth case, respectively. In addition, incremental equipment costs reflect a medium decline rate in the Primary Estimate, a constant 
rate in the Low-Net-Benefits Estimate, and a high decline rate in the High-Net-Benefits Estimate. The methods used to derive projected price trends are explained in sections IV.F.1 and IV.H.3 of the direct final rule published elsewhere in this issue of the Federal Register. Note that the 
Benefits and Costs may not sum to the Net Benefits due to rounding. 
* Climate benefits are calculated using four different estimates of the global SC–GHG (see section IV.L of the direct final rule published else-
where in this issue of the Federal Register). For presentational purposes of this table, the climate benefits associated with the average SC– GHG at a 3 percent discount rate are shown, but DOE does not have a single central SC–GHG point estimate, and it emphasizes the impor-tance and value of considering the benefits calculated using all four sets of SC–GHG estimates. To monetize the benefits of reducing GHG emis-sions, 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 the direct final rule published elsewhere in this issue of the Federal 
Register for more details. 
† Total benefits for both the 3-percent and 7-percent cases are presented using the average SC–GHG with 3-percent discount rate, but DOE 
does not have a single central SC–GHG point estimate. 
‡Costs include incremental equipment costs as well as installation costs. 
‡‡Operating Cost Savings are calculated based on the life cycle costs analysis and national impact analysis. See sections IV.F and IV.H of 
the direct final rule published elsewhere in this issue of the Federal Register. 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 experi-enced by the consumer. DOE also separately conducts a detailed analysis on the impacts on manufacturers (the MIA). See section IV.J of the 
direct final rule published elsewhere in this issue of the Federal Register and chapter 12 of the direct final rule TSD. 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 7.5 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 consumer clothes dryers, those values are ¥$12 million to ¥$10 million. DOE accounts for that range of likely impacts in analyzing whether a TSL is economically justified. See 
section V.C of the direct final rule published elsewhere in this issue of the Federal Register. DOE is presenting the range of impacts to the INPV under two manufacturer markup scenarios: the Preservation of Gross Margin scenario, which is the manufacturer markup scenario used in the calculation of Consumer Operating Cost Savings in this table, and the Preservation of Operating Profit scenario, where DOE assumed manufac-turers 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 chapter 12 of the direct final rule TSD, to provide additional context for assessing the estimated impacts of this proposed rule to society, including potential changes in production and con-sumption, 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 calcula-tion for this proposed rule, the annualized net benefits would range from $1,642 million to $1,644 million at 3-percent discount rate and would range from $1,345 million to $1,347 million at 7-percent discount rate. Parentheses ( ) indicate negative values.

B. Public Meeting 
As stated previously, if DOE 
withdraws the direct final rule 
published elsewhere in this issue of the Federal Register pursuant to 42 U.S.C. 6295(p)(4)(C), DOE will hold a public meeting to allow for additional comment on this proposed rule. DOE will publish notice of any meeting in the Federal Register. 
V. Procedural Issues and Regulatory Review 
The regulatory reviews conducted for 
this proposed rule are identical to those conducted for the direct final rule published elsewhere in this issue of the Federal Register. Please see the direct final rule for further details. A. Review Under the Regulatory Flexibility Act 
The Regulatory Flexibility Act (5 
U.S.C. 601 et seq.) requires preparation of an initial regulatory flexibility analysis (‘‘IRFA’’) and a final regulatory flexibility analysis (‘‘FRFA’’) for any rule that by law must be proposed for public comment, unless the agency certifies that the rule, if promulgated, will not have a significant economic impact on a substantial number of small entities. As required by E.O. 13272, ‘‘Proper Consideration of Small Entities in Agency Rulemaking,’’ 67 FR 53461 (Aug. 16, 2002), DOE published procedures and policies on February 19, 2003, to ensure that the potential impacts of its rules on small entities are properly considered during the rulemaking process. 68 FR 7990. DOE has made its procedures and policies available on the Office of the General Counsel’s website (www.energy.gov/gc/ office-general-counsel). DOE has not prepared an IRFA for the products that are the subject of this proposed rulemaking. 
DOE reviewed this proposed rule 
under the provisions of the Regulatory Flexibility Act and the procedures and policies published on February 19, 2003. DOE certifies that the proposed rule, if adopted, would not have significant economic impact on a substantial number of small entities. The factual basis of this certification is set forth in the following paragraphs. 
For manufacturers of consumer 
clothes dryers, the Small Business Administration (‘‘SBA’’) has set a size threshold, which defines those entities classified as ‘‘small businesses’’ for the purposes of the statute. DOE used the SBA’s small business size standards to determine whether any small entities would be subject to the requirements of the rule. (See 13 CFR part 121.) The size standards are listed by North American Industry Classification System (‘‘NAICS’’) code and industry description and are available at www.sba.gov/document/support--table- size-standards. Manufacturing of 
consumer clothes dryers is classified under NAICS 335220, ‘‘Major Household Appliance Manufacturing.’’ The SBA sets a threshold of 1,500 employees or fewer for an entity to be considered as a small business for this category. 
To estimate the number of companies 
that could be small business manufacturers of consumer clothes dryers, DOE conducted a market survey using public information and subscription-based company reports to identify potential small business

California Energy Commission’s Modernized Appliance Efficiency Database System,
20the ENERGY STAR 
Product Finder dataset,21individual 
company websites, import/export logs, and product specifications to create a list of companies that manufacture, produce, import, or private label the products covered by this rulemaking. DOE relied on public information and market research tools (e.g., reports from 
Dun and Bradstreet
22) to determine 
company structure, location, headcount, and annual revenue. DOE screened out companies that do not manufacture the products covered by this proposed rulemaking, do not meet the SBA’s definition of a ‘‘small business,’’ or are foreign-owned and operated. DOE also asked stakeholders and industry representatives if they were aware of any small manufacturers during manufacturer interviews and through requests for comment. 
DOE identified 19 OEMs of consumer 
clothes dryers. Of these 19 OEMs, DOE determined none of them qualify as a domestic ‘‘small business manufacturer’’ of consumer clothes dryers. Given the lack of small domestic OEMs with a direct compliance burden, DOE concludes that this proposed rule would not have ‘‘a significant impact on a substantial number of small entities.’’ DOE will transmit the certification 
and supporting statement of factual 
basis to the Chief Counsel for Advocacy of the Small Business Administration for review under 5 U.S.C. 605(b).
