I. Synopsis of the Direct Final Rule

    The Energy Policy and Conservation Act, Public Law 94-163, as 
amended (``EPCA''),\1\ authorizes 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 consumer clothes dryers, the 
subject of this direct final rule. (42 U.S.C. 6292(a)(7))
---------------------------------------------------------------------------

    \1\ All references to EPCA in this document refer to the statute 
as amended through the Energy Act of 2020, Public Law 116-260 (Dec. 
27, 2020), which reflect the last statutory amendments that impact 
Parts A and A-1 of EPCA.
    \2\ For editorial reasons, upon codification in the U.S. Code, 
Part B was redesignated Part A.
---------------------------------------------------------------------------

    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 consumer clothes dryers.
    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'',) \3\ recommends specific energy 
conservation standards for consumer clothes dryers that, in the 
commenters' view, would satisfy the EPCA requirements in 42 U.S.C. 
6295(o). DOE subsequently received letters of support from States--
including New York, California, and Massachusetts \4\--and utilities--
including San Diego Gas and Electric (``SDG&E'') and Southern 
California Edison (``SCE'') \5\--advocating for the adoption of the 
recommended standards.

---------------------------------------------------------------------------

    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 
elsewhere in this Federal Register a notice of proposed rulemaking 
(``NOPR'') that contains standards identical 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 Table I.1). The standards are expressed in terms of the 
combined energy factor (``CEF<INF>D2</INF>''), 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. The amended standards recommended in the Joint 
Agreement are represented as trial standard level (``TSL'') 3 
(hereinafter the ``Recommended TSL'') and are described in section V.A 
of this document. The Joint Agreement's standards for consumer clothes 
dryers apply to all products listed in Table I.1 and manufactured in, 
or imported into, the United States starting on March 1, 2028.

A. Benefits and Costs to Consumers

    Table I.2 summarizes DOE's evaluation of the economic impacts of 
the adopted standards on consumers of consumer clothes dryers, as 
measured by the average life-cycle cost (``LCC'') savings and the 
simple payback period (``PBP'').\6\ The average LCC savings are 
positive for all product classes, and the PBP is less than the average 
lifetime of consumer clothes dryers, which is estimated to be 14 years 
(see section IV.F of this document).
---------------------------------------------------------------------------

    \6\ The average LCC savings refer to consumers that 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 document).

------------------------------------------------------------------------

    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

    The industry net present value (``INPV'') is the sum of the 
discounted cash flows to the industry from the base year (2024) through 
the end of the analysis period, which is 30 years from the analyzed 
compliance date.\7\ Using a real discount rate of 7.5 percent, DOE 
estimates that the INPV for manufacturers of consumer clothes dryers in 
the case without amended standards is $2.12 billion in 2022$.\8\ Under 
the adopted standards, which align with the Recommended TSL for 
consumer clothes dryers, DOE estimates the change in INPV to range from 
-6.8 percent to -5.7 percent, which is a decrease of approximately 
$144.2 million to a decrease of approximately $119.7 million. In order 
to bring products into compliance with amended standards, it is 
estimated that industry will incur total conversion costs of $180.7 
million.
---------------------------------------------------------------------------

    \7\ DOE's analysis period extends 30 years from the compliance 
year. The analysis period for the MIA ranges from 2024-2056 for the 
no-new-standards case and all TSLs, except for TSL 3 (the 
Recommended TSL). The analysis period for the Recommended TSL ranges 
from 2024-2057 due to the 2028 compliance year.
    \8\ The no-new-standards case INPV of $2.12 billion reflects the 
sum of discounted free cash flows from 2024-2056 (from the reference 
year to 30 years after the 2027 compliance date) plus a discounted 
terminal value.
---------------------------------------------------------------------------

    DOE's analysis of the impacts of the adopted standards on 
manufacturers is described in section IV.J and section V.B.2 of this 
document.

C. National Benefits and Costs <SUP>9</SUP>
---------------------------------------------------------------------------

    \9\ All monetary values in this document are expressed in 2022 
dollars and, where appropriate, are discounted to 2024 unless 
explicitly stated otherwise.
---------------------------------------------------------------------------

    DOE's analyses indicate that the adopted energy conservation 
standards for consumer clothes dryers would save a significant amount 
of energy. Relative to the case without amended standards, the lifetime 
energy savings for consumer clothes dryers purchased in the 30-year 
period that begins in the anticipated year of compliance with the 
amended standards (2028-2057), amount to 2.7 quadrillion British 
thermal units (``Btu''), or quads.\10\ This 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'').
---------------------------------------------------------------------------

    \10\ The 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 IV.H.2 of this document.
---------------------------------------------------------------------------

    The cumulative net present value (``NPV'') of total consumer 
benefits of the standards for consumer clothes dryers ranges from $ 
9.23 billion (at a 7-percent discount rate) to $20.08 billion (at a 3-
percent discount rate). This NPV expresses the estimated total value of 
future operating-cost savings minus the estimated increased product and 
installation costs for consumer clothes dryers purchased during the 
period 2028-2057.
    In addition, the adopted standards for consumer clothes dryers are 
projected to yield significant environmental benefits. DOE estimates 
that the standards will result in cumulative emission reductions (over 
the same period as for

[[Page 18167]]

energy savings) of 57.1 million metric tons (``Mt'') \11\ of carbon 
dioxide (``CO<INF>2</INF>''), 13.9 thousand tons of sulfur dioxide 
(``SO<INF>2</INF>''), 116.5 thousand tons of nitrogen oxides 
(``NO<INF>X</INF>''), 527.6 thousand tons of methane 
(``CH<INF>4</INF>''), 0.5 thousand tons of nitrous oxide 
(``N<INF>2</INF>O''), and 0.1 tons of mercury (``Hg'').\12\ The 
estimated cumulative reduction in CO<INF>2</INF> emissions through 2030 
amounts to 1.3 Mt, which is equivalent to the emissions resulting from 
the annual electricity use of more than 260 thousand homes.
---------------------------------------------------------------------------

    \11\ A metric ton is equivalent to 1.1 short tons. Results for 
emissions other than CO<INF>2</INF> are presented in short tons.
    \12\ DOE 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.
---------------------------------------------------------------------------

    DOE estimates the value of climate benefits from a reduction in 
greenhouse gases (``GHG'') using four different estimates of the social 
cost of CO<INF>2</INF> (``SC-CO<INF>2</INF>''), the social cost of 
methane (``SC-CH<INF>4</INF>''), and the social cost of nitrous oxide 
(``SC-N<INF>2</INF>O''). Together these represent the social cost of 
GHG (``SC-GHG''). DOE used interim SC-GHG values (in terms of benefit 
per ton of GHG avoided) developed by an Interagency Working Group on 
the Social Cost of Greenhouse Gases (``IWG'').\13\ The 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 $3.3 
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.
---------------------------------------------------------------------------

    \13\ 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. (``February 2021 SC-GHG TSD''). <a href="http://www.whitehouse.gov/wp-content/uploads/2021/02/TechnicalSupportDocument_SocialCostofCarbonMethaneNitrousOxide.pdf">www.whitehouse.gov/wp-content/uploads/2021/02/TechnicalSupportDocument_SocialCostofCarbonMethaneNitrousOxide.pdf</a>.
---------------------------------------------------------------------------

    DOE estimated the monetary health benefits of SO<INF>2</INF> and 
NO<INF>X</INF> emissions reductions, using benefit-per-ton estimates 
from the Environmental Protection Agency,\14\ as discussed in section 
IV.L of this document. DOE estimated the present value of the health 
benefits would be $2.6 billion using a 7-percent discount rate, and 
$6.3 billion using a 3-percent discount rate.\15\ DOE is currently only 
monetizing health benefits from changes in ambient fine particulate 
matter (PM<INF>2.5</INF>) concentrations from two precursors 
(SO<INF>2</INF> and NO<INF>X</INF>), and from changes in ambient ozone 
from one precursor (for NO<INF>X</INF>), but will continue to assess 
the ability to monetize other effects such as health benefits from 
reductions in direct PM<INF>2.5</INF> emissions.

Note: This table presents the costs and benefits associated with
  consumer clothes dryers shipped in 2028-2057. These results include
  consumer, climate, and health benefits that accrue after 2057 from the
  products shipped in 2028-2057.
* 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
  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 NOX
  and SO2. DOE is currently only monetizing (for SO2 and NOX) PM2.5
  precursor health benefits and (for NOX) ozone precursor health
  benefits, but will continue to assess the ability to monetize other
  effects such as health benefits from reductions in direct PM2.5
  emissions. See section IV.L of this document for more details.
[dagger] 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 a 3-percent discount
  rate.
[Dagger] Costs include incremental equipment costs as well as
  installation costs.

[[Page 18168]]

 
[Dagger][Dagger] 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 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 and chapter 12 of the direct
  final rule technical support document (``TSD''). In the detailed MIA,
  DOE models manufacturers' pricing decisions based on assumptions
  regarding investments, conversion costs, cashflow, and margins. The
  MIA produces a range of impacts, which is the rule's expected impact
  on the INPV. The change in INPV is the present value of all changes in
  industry cash flow, including changes in production costs, capital
  expenditures, and manufacturer profit margins. Change in INPV is
  calculated using the industry weighted average cost of capital value
  of 7.5 percent that is estimated in the MIA (see chapter 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 -$144 million to -$120 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
  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
  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 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 $19.96 billion to
  $19.98 billion at 3-percent discount rate and would range from $9.06
  billion to $9.08 billion at 7-percent discount rate. Parentheses ( )
  indicate negative values.

    The benefits and costs of the adopted 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\
---------------------------------------------------------------------------

    \16\ To convert the time-series of costs and benefits into 
annualized values, DOE calculated a present value in 2024, 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 2024. 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 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 consumer clothes 
dryers shipped in 2028-2057. The benefits associated with reduced 
emissions achieved as a result of the adopted standards are also 
calculated based on the lifetime of consumer clothes dryers shipped in 
2028-2057. Total benefits for both the 3-percent and 7-percent cases 
are presented using the average GHG social costs with a 3-percent 
discount rate. Estimates of SC-GHG values are presented for all four 
SC-GHG discount rates in section IV.L of this document.
    Table I.4 presents the total estimated monetized benefits and costs 
associated with the adopted standards, 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<INF>X</INF> and SO<INF>2</INF> 
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 $60.0 million per year in increased equipment costs, 
while the estimated annual benefits are $971.4 million in reduced 
equipment operating costs, $185.5 million in climate benefits, and 
$259.9 million in health benefits. 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 standards is $57.2 million per year in increased 
equipment costs, while the estimated annual benefits are $1,177 million 
in reduced operating costs, $185.5 million in climate benefits, and 
$349.4 million in health benefits. 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 in 2028-2057.
  These results include benefits to consumers which accrue after 2057 from the products shipped in 2028-2057.
  The Primary, Low-Net-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 this document. Note that the Benefits
  and Costs may not sum up 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, but DOE does not have a single central SC-GHG point estimate, and it
  emphasizes the importance and value of considering the benefits calculated using all four sets of SC-GHG
  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 NOX and SO2. DOE is currently only monetizing
  (for SO2 and NOX) PM2.5 precursor health benefits and (for NOX) ozone precursor health benefits, but will
  continue to assess the ability to monetize other effects such as health benefits from reductions in direct
  PM2.5 emissions. See section IV.L of this document for more details.
[dagger] Total benefits for both the 3-percent and 7-percent cases are presented using the average SC-GHG with a
  3-percent discount rate, but DOE does not have a single central SC-GHG point estimate.
[Dagger] Costs include incremental equipment costs as well as installation costs.
[Dagger][Dagger] 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 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 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 produces a range of impacts, which is the rule's expected impact on the INPV.
  The change in INPV is the present value of all changes in industry cash flow, including changes in production
  costs, capital expenditures, and manufacturer profit margins. The annualized change in INPV is calculated
  using the industry weighted average cost of capital value of 7.5 percent that is estimated in the manufacturer
  impact analysis (see chapter 12 of the direct final rule TSD for a complete description of the industry
  weighted average cost of capital). For 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 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 chapter 12 of this direct final
  rule TSD, to provide additional 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 annualized net benefit calculation for this direct
  final rule, the annualized net benefits, using the primary estimate, would range from $1,642 million to $1,644
  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.

    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 of Energy 
(``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<INF>X</INF> and SO<INF>2</INF> reduction benefits, and a 3-percent 
discount rate case for GHG social costs, the estimated cost of the 
standards for consumer clothes dryers is $60.0 million per year in 
increased product costs, while the estimated annual benefits are $971.4 
million in reduced product operating costs, $185.5 million in climate 
benefits, and $259.9 million in health benefits. The net benefit 
amounts to $1,357 million per year. DOE notes that the net benefits are 
substantial even in the absence of the climate benefits,\17\ and DOE 
would adopt the same standards in the absence of such benefits.
---------------------------------------------------------------------------

    \17\ The information on climate benefits is provided in 
compliance with Executive Order 12866.
---------------------------------------------------------------------------

    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.\18\ For 
example, some covered products and equipment have most of their energy 
consumption occur during periods of peak energy demand.

[[Page 18170]]

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 2.7 quads FFC, the equivalent of 
the primary annual energy use of 18 million homes. In addition, they 
are projected to reduce cumulative CO<INF>2</INF> emissions by 57.1 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.
    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 consumer clothes dryers. 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 
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 in limited instances for particular State laws or 
regulations, in accordance with the procedures and other provisions set 
forth under EPCA. (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 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 
(``appendix D1'') and appendix D2 (``appendix D2'').
    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 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)(3)(B)) 
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 evidence that the standard is likely to result in the 
unavailability in the United States in

[[Page 18171]]

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 for consumer clothes 
dryers 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 directly 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. 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 (``Process Rule'' or ``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 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.\19\ These standards are set forth in DOE's 
regulations at 10 CFR 430.32(h)(3) and are shown in Table II.1. These 
standards are consistent with a prior joint proposal submitted to DOE 
by interested parties representing manufacturers, energy and 
environmental advocates, and consumer groups.\20\
---------------------------------------------------------------------------

    \19\ DOE published a confirmation of effective date and 
compliance date for the direct final rule on August 24, 2011. 76 FR 
52854.
    \20\ Available at: <a href="http://www.regulations.gov/comment/EERE-2007-BT-STD-0010-0049">www.regulations.gov/comment/EERE-2007-BT-STD-0010-0049</a>.
---------------------------------------------------------------------------

    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.\21\ To 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<INF>D1</INF>'' and ``CEF<INF>D2</INF>'').
---------------------------------------------------------------------------

    \21\ While 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 direct final rule, manufacturers will be 
required to use appendix D2 to comply with the amended standards.

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<INF>D1</INF>. (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 measures 
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 dried until the FMC is between 1 and 
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.\22\ DOE 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 direct final 
rule based on CEF<INF>D2</INF> because compliance with the amended 
energy conservation standards established in this direct final rule 
must be determined based on the use of appendix D2. DOE discusses 
additional details in section IV.C.1 of this document about how it 
developed the engineering baseline, in terms of CEF<INF>D2</INF>, from 
the current consumer clothes dryer standards that are in terms of 
CEF<INF>D1</INF>.
3. The Joint Agreement
    On September 25, 2023, DOE received a joint statement of 
recommended standards (i.e., the Joint Agreement) for various home 
appliance products, including consumer clothes dryers, submitted 
jointly by groups representing manufacturers, energy and environmental 
advocates, consumer groups, and a utility.\23\ In addition to the

[[Page 18173]]

recommended standards for consumer clothes dryers, the Joint Agreement 
also included separate recommendations for several other covered 
products.\24\ And, 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.
---------------------------------------------------------------------------

    \23\ The signatories to the Joint Agreement include AHAM, 
American Council for an Energy-Efficient Economy, Alliance for Water 
Efficiency, Appliance Standards Awareness Project, Consumer 
Federation of America, Consumer Reports, Earthjustice, National 
Consumer Law Center, Natural Resources Defense Council, Northwest 
Energy Efficiency Alliance, and Pacific Gas and Electric Company. 
Members of AHAM's Major Appliance Division that make the affected 
products include: Alliance Laundry Systems, LLC; Asko Appliances AB; 
Beko US Inc.; Brown Stove Works, Inc.; BSH Home Appliances 
Corporation; Danby Products, Ltd.; Electrolux Home Products, Inc.,; 
Elicamex S.A. de C.V.; Faber; Fotile America; GE Appliances, a Haier 
Company; L'Atelier Paris Haute Design LLG; LG Electronics; Liebherr

Corporation; Smeg S.p.A; Sub-Zero Group, Inc.; The Middleby 
Corporation; U-Line Corporation; Viking Range, LLC; and Whirlpool 
Corporation.
    \24\ The Joint Agreement contained recommendations for 6 covered 
products: refrigerators, refrigerator-freezers, and freezers; 
clothes washers; clothes dryers; dishwashers; cooking products; and 
miscellaneous refrigeration products.
---------------------------------------------------------------------------

    A court decision issued after DOE received the Joint Agreement is 
also relevant to this 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.\25\ In the letter, the signatories clarified that ``short-
cycle'' product classes for RCWs, 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 features or performance, including cycle time, for 
consumer clothes dryers.

    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 meeting on August 23, 2022 (``August 2022 NOPR'') seeking 
comment on its proposed amended standard to inform its decision 
consistent with its obligations under EPCA and the Administrative 
Procedure Act (``APA''). 87 FR 51734. DOE subsequently held a public 
webinar on September 13, 2022, to discuss and receive comments on the 
NOPR TSD.
    Although DOE is adopting the Joint Agreement as a direct final rule 
and no

[[Page 18174]]

longer proceeding with its prior 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 prior rulemaking will include a parenthetical

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).
    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 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)
    Following the Fifth Circuit's decision, the signatories to the 
Joint Agreement submitted a second letter to DOE, which stated that 
Joint Recommendation did not ``address'' ``short-cycle product 
classes.'' \29\ That is because, as the letter explained, such product 
classes ``did not exist'' at the time of the Joint Agreement.
---------------------------------------------------------------------------

    \29\ This document is available in the docket at: 
<a href="http://www.regulations.gov/comment/EERE-2014-BT-STD-0058-0058">www.regulations.gov/comment/EERE-2014-BT-STD-0058-0058</a>.
---------------------------------------------------------------------------

    In a recently issued Request for Information,\30\ DOE 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. . . .''
---------------------------------------------------------------------------

    \30\ See <a href="https://www1.eere.energy.gov/buildings/appliance_standards/standards.aspx?productid=50">https://www1.eere.energy.gov/buildings/appliance_standards/standards.aspx?productid=50</a>.
---------------------------------------------------------------------------

    The current standards applicable to any products within the scope 
of that proceeding remain unchanged by this rule. See 10 CFR 430.32(g). 
Consistent with the Joint Parties' letter, short-cycle products are not 
subject to the amended standards adopted by this direct final rule. If 
the short-cycle products that DOE will consider in the Remand 
Proceeding were subject to these standards, that would have the 
practical effect of limiting the options available in the Remand 
Proceeding. That is because EPCA's anti-backsliding provision precludes 
DOE from prescribing any amended standard ``which increases the maximum 
allowable energy use'' of a covered product. 42 U.S.C. 6295(o)(1). 
Accordingly, were the products at issue in the Remand Proceeding also 
subject to the amended standards adopted here, the Department could 
only reaffirm the standards adopted in this direct final rule or adopt 
more stringent standards.
    The Joint Agreement specifies the product classes for consumer 
clothes dryers: electric, standard; electric, compact; vented electric, 
compact; vented gas, standard; vented gas, compact; ventless electric, 
compact; and ventless electric, combination washer-dryer. Although 
these product classes were not further divided by cycle time, DOE 
understands them to exclude vented electric standard-size clothes 
dryers and vented gas standard-size clothes dryers with a cycle time of 
less than 30 minutes, when tested according to appendix D2. As 
previously noted, any such ``short-cycle'' consumer clothes dryers will 
be considered in the Remand Proceeding; the current standards 
applicable to such ``short-cycle'' consumer clothes dryers are 
unchanged by this rule.
    Under the direct final rule authority at 42 U.S.C. 6295(p)(4), DOE 
evaluates whether recommended standards are in accordance with criteria 
contained in 42 U.S.C. 6295(o). DOE does not have the authority to 
revise recommended standards submitted under the direct final rule 
provision in EPCA. Therefore, DOE did not analyze any additional 
product classes beyond those product classes included in the Joint 
Agreement. That is, DOE has not separately considered or established 
amended standards applicable to any short-cycle product classes. In the 
event that DOE establishes short-cycle product classes, pursuant to the 
rulemaking on remand from the Fifth Circuit, DOE will necessarily 
consider what amended standards ought to apply to any such product 
classes and will do so in conformance with EPCA.
    DOE notes that the data and analysis used to support this direct 
final rule includes information for vented electric standard-size 
clothes dryers and vented gas standard-size clothes dryers that is not 
distinguished by cycle time and is representative of all consumer 
clothes dryers currently on the market today. To the extent that any 
short cycle product classes were included in this data and analysis, 
DOE believes the amount of such data is negligible.

A. Scope of Coverage

    Before discussing how the Joint Agreement meets the requirements 
for issuing a direct final rule, it is important to clarify the scope 
of coverage for the recommended standards. EPCA does not define the 
term ``clothes dryer.'' (See 42 U.S.C. 6291) DOE has defined an 
``electric clothes dryer'' as a cabinet-like appliance designed to dry 
fabrics in a tumble-type drum with forced air circulation. The heat 
source is electricity and the drum and blower(s) are driven by an 
electric motor(s). 10 CFR 430.2. DOE has defined a ``gas clothes 
dryer'' as a cabinet-like appliance designed to dry fabrics in a 
tumble-type drum with forced air circulation. The heat source is gas 
and the drum and blower(s) are driven by an electric motor(s). Id. This 
direct final rule covers consumer clothes dryers, i.e., those consumer 
products that meet the definitions of ``electric clothes dryer'' and 
``gas clothes dryer,'' as codified at 10 CFR 430.2.
    See section IV.A.1 of this document for discussion of 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

[[Page 18175]]

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 11 manufacturers of consumer clothes dryers.\31\ 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. 56). DOE also received a letter in 
support of the Joint Agreement from a gas and electric utility, SDG&E, 
and an electric utility, SCE (See comment No. 57). As a result, DOE has 
determined that the Joint Agreement was submitted by interested persons 
who are fairly representative of relevant points of view.
---------------------------------------------------------------------------

    \31\ These companies include: Alliance Laundry Systems, LLC; 
Beko US Inc.; BSH Home Appliances Corporation; Danby Products, Ltd.; 
Electrolux Home Products, Inc.; GE Appliances, a Haier Company; LG 
Electronics; Midea America Corp.; Miele, Inc.; Samsung Electronics 
America Inc.; and Whirlpool Corporation.
---------------------------------------------------------------------------

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. In evaluating the recommended standards proposed in the 
Joint Agreement, DOE conducted the same analysis. 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.
    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. 
Sections 7(b)(2)-(5) of appendix A. Section IV.B of this document 
discusses the results of the screening analysis for consumer clothes 
dryers, 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 consumer 
clothes dryers 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 TSL considered, DOE projected energy savings from 
application of the TSL to consumer clothes dryers purchased in the 30-
year period that begins in the year of compliance with the amended 
standards (2027-2056 for all TSLs except the Recommended TSL (i.e., TSL 
3) and 2028-2057 for TSL 3).\32\ The savings are measured over the 
entire lifetime of consumer clothes dryers 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.
---------------------------------------------------------------------------

    \32\ DOE also presents a sensitivity analysis that considers 
impacts for products shipped in a 9-year period.
---------------------------------------------------------------------------

    DOE used its national impact analysis (``NIA'') spreadsheet models 
to estimate national energy savings (``NES'') from potential amended 
standards for consumer clothes dryers. 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 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.\33\ DOE's approach is based on the calculation of an FFC 
multiplier for each of the energy types used by covered products or 
equipment. For more information on FFC energy savings, see section 
IV.H.2 of this document.
---------------------------------------------------------------------------

    \33\ The 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).
---------------------------------------------------------------------------

2. Significance of Savings
    To adopt any new or amended standards for a covered product 
including through a direct final rule, 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.\34\ For 
example, some covered products and equipment have most of their energy 
consumption occur during periods of peak energy demand. The impact 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, 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.
---------------------------------------------------------------------------

    \34\ Procedures, Interpretations, and Policies for 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).
---------------------------------------------------------------------------

    As stated, the standard levels adopted in this direct final rule 
are projected to result in national energy savings of 2.7 quads, the 
equivalent of the electricity

[[Page 18176]]

use of 18 million homes in one year. Based on the amount of FFC 
savings, the corresponding reduction in emissions, and the 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 direct final rulemaking.
a. Economic Impact on Manufacturers and Consumers
    In determining the impacts of 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 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 the recommended 
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 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

[[Page 18177]]

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 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 regarding consumer clothes dryers. 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 consumer clothes dryers 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: <a href="http://www.regulations.gov/docket/EERE-2014-BT-STD-0058">www.regulations.gov/docket/EERE-2014-BT-STD-0058</a>. Additionally, DOE used output from the 
latest version of the Energy Information Administration's (``EIA's'') 
Annual Energy Outlook 2023 (``AEO2023'') 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 consumer clothes dryers. 
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 seven product classes for consumer 
clothes dryers. (Joint Agreement, No. 55 at p. 9). In this direct final 
rule, DOE is adopting the product classes from the Joint Agreement, as 
listed in Table IV.1.

   Table IV.1--Joint Agreement Consumer Clothes Dryer Product Classes
------------------------------------------------------------------------
                             Product classes
-------------------------------------------------------------------------
1. Electric, Standard (4.4 ft3 or greater capacity)
2. Electric, Compact (120V) (less than 4.4 ft3 capacity)
3. Vented Electric, Compact (240V) (less than 4.4 ft3 capacity)
4. Vented Gas, Standard (4.4 ft3 or greater capacity)
5. Vented Gas, Compact (less than 4.4 ft3 capacity)
6. Ventless Electric, Compact (240V) (less than 4.4 ft3 capacity)
7. Ventless Electric, Combination Washer-Dryer
------------------------------------------------------------------------

    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. However, 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.\35\ Additionally, 
DOE notes that DOE's findings in this regard are discussed in detail in 
section V.B.4 of this document.
---------------------------------------------------------------------------

    \35\ EPCA 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. (42 U.S.C. 6295(o)(4))
---------------------------------------------------------------------------

2. Technology Options
    In this direct final rule, DOE considered the technology options 
listed in Table IV.2, consistent with the table of technology options 
presented in the August 2022 NOPR. 87 FR 51734. Chapter 3 of the TSD 
for this direct final

[[Page 18178]]

rule includes a detailed list and descriptions of all technology 
options identified for consumer clothes dryers. As discussed in chapter 
3 of the TSD for this direct final rule, DOE has performed market 
research and evaluated available consumer clothes dryers to assess 
existing technology options to improve efficiency. The results of this 
research are discussed in chapter 3 of the TSD for this direct final 
rule. DOE notes that it did not receive any comments regarding the 
technology options analyzed in the August 2022 NOPR.

 Table IV.2--Direct Final Rule Analysis: Technology Options for Consumer

------------------------------------------------------------------------

B. Screening Analysis

    DOE uses the following 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 sum, 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 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 August 2022 NOPR.
a. Thermoelectric Heating, Electric Only
    DOE notes that thermoelectric heating clothes dryers are still 
undergoing preliminary research, including at Oak Ridge National 
Laboratory (``ORNL''). While ORNL's test results of a preliminary 
prototype have shown the potential for improved efficiency, ORNL 
indicated that the initial prototype design produced longer-than-
desired drying times due to direct-contact heat transfer limitations 
via the drum surface. ORNL subsequently developed another prototype 
that added pumped secondary water loops that transferred heat from the 
thermoelectric modules to the process air via air-to-water heat 
exchangers to further improve efficiency and minimize cycle length. 
ORNL's testing indicated efficiency and cycle times for this prototype 
that are approximately equivalent to those of vapor compression heat 
pump clothes dryers.\36\ Because the research for such a thermoelectric 
heating clothes dryer that produces energy savings and meets consumer 
expectations for drying cycle time is still in the prototype stage, DOE 
determined that this technology option would not be practicable to 
manufacture, install, and service on a scale necessary to serve the 
relevant market at the time of the projected compliance date of any new 
or amended consumer clothes dryer standards, and did not consider it 
for further analysis.

b. Microwave, Electric Only
    Due to the large energy savings associated with microwave drying, 
this technology was the subject of a multiyear development effort at 
the Electric Power Research Institute (``EPRI'') in the mid-1990s.\37\ 
At least one major manufacturer--Whirlpool--developed a countertop-
scale version of such a product as recently as 2002,\38\ but to date 
this technology has not been successfully commercialized.

    Microwave drying introduces significant technical and safety issues 
with potential arcing from metallic objects in the fabric load, 
including zippers, buttons, or ``stray'' items such as coins. While 
efforts have been made to mitigate the conditions that are favorable to 
arcing or to detect incipient arcing and terminate the cycle, the 
possibility of fabric damage cannot be completely eliminated.\39\ In 
addition to those consumer utility impacts, these conditions can also 
pose a safety hazard. For these reasons, microwave drying was not 
considered further for analysis.

c. Indirect Heating
    Indirect heating would be viable only in residences that use a 
hydronic heating system. Also, in order to derive clothes dryer heat 
energy from a home's heating system, significant plumbing work would be 
required to circulate heated water through a heat exchanger in the 
clothes dryer. Therefore, this technology option does not meet the 
criterion of practicability to install on a scale necessary to serve 
the relevant market at the time of the effective date of any new 
standard and was not considered for further analysis.
d. RF Drying, Electric Only
    CoolDry, LLC (``CoolDry'') developed an RF clothes dryer prototype, 
claiming an efficiency of 90 percent, compared to 50 percent for 
conventional clothes dryers.\40\ CoolDry stated that its RF drying 
technology operates at lower temperatures than do conventional clothes 
dryers and, because the transfer of energy to clothes is not dependent 
on convective heat transfer, the RF clothes dryer requires less 
tumbling and subsequently consumes less energy for drum rotation than a 
conventional clothes dryer. Because this technology was in the 
prototype stage at the time it was initially considered and the company 
is no longer in business, research and development is unlikely to be 
ongoing. Therefore, DOE determined that this technology option would 
not be practicable to manufacture, install, and service on a scale 
necessary to serve the relevant market at the time of the projected 
compliance date of any new or amended consumer clothes dryer standards 
and did not consider it for further analysis.
---------------------------------------------------------------------------

    \40\ Cool Dry did not specify the metric or test method used to 
determine the efficiency of its prototype.
---------------------------------------------------------------------------

e. Ultrasonic Drying, Electric Only
    Researchers at ORNL have developed an ultrasonic drying prototype 
that uses piezoelectric transducers to separate water from clothes 
through water cavitation produced by ultrasonic vibrations. According 
to their research, the energy imparted to the water must overcome 
surface tension in order to break the water into droplets, but this 
energy is substantially less than the latent heat of vaporization of 
water, which is the primary thermodynamic barrier for conventional 
evaporation drying. The ORNL researchers anticipate that ultrasonic 
drying technology will result in an energy factor \41\ of greater than 
10 and a drying time of less than 20 minutes.\42\ Because this 
technology is still in the prototype stage, however, DOE determined 
that this technology option would not be practicable to manufacture, 
install, and service on a scale necessary to serve the relevant market 
at the time of the projected compliance date of any new or amended 
consumer clothes dryer standards and did not consider it for further 
analysis.
---------------------------------------------------------------------------

    \41\ This energy factor incorporates only active mode energy use 
and not standby mode and off mode energy use.

---------------------------------------------------------------------------

    DOE did not receive any comments in response to the August 2022 
NOPR regarding these screened out technology options, and for the 
reasons discussed, screened out the same technologies for this direct 
final rule analysis.
2. Remaining Technologies
    Through a review of each technology, DOE tentatively concludes that 
all of the other identified technologies listed in section IV.A.2 of 
this document met all screening criteria to be examined further as 
design options in DOE's direct final rule analysis. In summary, DOE did 
not screen out the following technology options:

     Table IV.3--Retained Design Options for Consumer Clothes Dryers
------------------------------------------------------------------------
 
-------------------------------------------------------------------------
Dryer Control or Drum Upgrades:
    Improved termination
    Modified operating conditions
    Improved air circulation
    Increased insulation
    Improved drum design
Methods of Exhaust Heat Recovery (vented models only):
    Recycle exhaust heat
    Inlet air preheat
    Inlet air preheat, condensing mode
Moisture Removal Options:
    Heat pump, electric only
    Modulating heat
Component Improvements:
    Improved motor efficiency
    Improved fan efficiency
Standby Power Improvements:
    Transformerless Power Supply with Auto-Powerdown
------------------------------------------------------------------------


[[Page 18180]]

    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.
    As previously discussed, on February 14, 2024, DOE received a 
second joint statement from the same group of stakeholders that 
submitted the Joint Agreement in which the signatories reaffirmed the 
standards recommended in the Joint Agreement.\43\ In particular, the 
letter states that the joint stakeholders do not anticipate the 
recommended standards will negatively affect features or performance.

C. Engineering Analysis

    The purpose of the engineering analysis is to establish the 
relationship between the efficiency and cost of consumer clothes 
dryers. 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 
the 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 to interpolate to define ``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).
    For this direct final rule, DOE used an efficiency-level approach, 
supplemented with reverse engineering. This approach involved first 
testing and then physically disassembling a representative sample of 
commercially available products, reviewing publicly available cost 
information, and modeling equipment cost. From this information and 
through the reverse engineering process, DOE estimated the manufacturer 
production costs (``MPCs'') for a range of products currently available 
on the market, considering the design options and the steps 
manufacturers would likely take to reach a certain efficiency level. As 
part of this analysis, DOE included test units that represent baseline 
models, newly introduced units on the market, units with unique 
configurations, and units with technologies as observed in the 
technology assessment. The efficiency levels analyzed as part of this 
engineering analysis are attainable using commercially available 
clothes dryer technologies, or technologies that have been demonstrated 
in working prototypes.
a. Baseline Efficiency Levels
    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.
    The baseline clothes dryer efficiency levels for this direct final 
rule differ from the existing energy conservation standards that were 
established in the 2011 rulemaking analysis primarily due to the 
difference between the then-current appendix D1, which DOE used to 
evaluate products in the previous rulemaking, and the present version 
of appendix D2, established in the October 2021 TP Final Rule and which 
DOE used as the basis for this analysis. Appendix D2 includes test 
methods that more accurately measure the effects of automatic cycle 
termination and that may result in differences in the total measured 
energy consumption of the test cycle as compared to the test methods in 
appendix D1. Specifically, for automatic termination control dryers, 
appendix D2 requires a lower FMC of the test load and does not rely on 
a field use factor to account for the over-drying energy consumption, 
instead requiring that the automatic termination drying program run to 
the end of the cycle. Additionally, appendix D2 contains instructions 
for the testing of timer dryers, which include a lower FMC of the test 
load as compared to the version of appendix D1 used for the 2011 
rulemaking analysis.
    For the engineering analysis, DOE began by identifying the 
efficiency level corresponding to the Federal minimum energy 
conservation standards for each product class. Due to the test 
procedure changes adopted in the October 2021 Final Rule, DOE 
determined the baseline efficiency level representative of minimally 
compliant products when tested under appendix D2. To identify the 
appendix D2 baseline levels, DOE tested 22 models that were certified 
as minimally compliant with the current energy conservation standards, 
from across all product classes. Because certified performance data are 
not available for models on the market tested in accordance with both 
appendix D1 and appendix D2, DOE tested each basic model in its test 
sample in accordance with appendix D1 and appendix D2 and used the test 
values for appendix D2 to determine the baseline models in support of 
this engineering analysis. Due to the differences in the two test 
procedures previously described, the baseline CEF<INF>D2</INF> measured 
using appendix D2 is numerically lower for each product class than the 
corresponding CEF<INF>D1</INF> value in the current energy conservation 
standards, though that does not indicate a lower efficiency. The test 
procedure differences drive the lower baseline

[[Page 18181]]

CEF<INF>D2</INF> values and do not represent a lower efficiency or 
backsliding.
    With regard to the vented gas compact product class, DOE is unaware 
of any currently available commercial products that fall within the 
vented gas compact product class. To determine the baseline level for 
this product class, DOE analyzed a vented gas compact-size model that 
was previously available on the market prior to the effective date of 
the current energy conservation. DOE's previous testing of that model--
which utilized electromechanical controls--suggests that the model 
would not be compliant with the existing standards. DOE expects that 
manufacturers would implement electronic controls as a design option to 
produce vented gas compact clothes dryers that minimally comply with 
the existing standard. DOE determined the efficiency performance that 
would be achieved through the addition of electronic controls by 
applying the same relative efficiency improvement observed with the 
implementation of electronic controls for standard-size vented gas 
clothes dryers, as shown in Table IV.8 in section IV.C.1.b of this 
document. The resulting estimated level of baseline performance for the 
vented gas compact product class is consistent with the efficiency 
level recommended by the Joint Agreement for this product class.
    The baseline efficiency levels considered for this analysis are 
presented along with the current standards in Table IV.4 and are 
discussed in more detail in chapter 5 of the direct final rule TSD. The 
baseline values are the same as those proposed in the August 2022 NOPR, 
except for the vented gas compact product class as discussed.

* As discussed, the baseline CEFD2 values represent differences in test
  procedure between appendix D1 and appendix D2 and do not constitute
  backsliding. CEFD2 baseline efficiency levels as measured under
  appendix D2 account for differences in the effectiveness of automatic
  cycle termination. Manufacturers implement automatic termination in a
  variety of ways, which will impact the representations as measured
  under appendix D2 and result in a range of possible CEFD2 values, as
  compared to the CEFD1 values in the existing Federal standards.

b. Incremental Efficiency Levels
    DOE developed incremental efficiency levels by reviewing products 
currently available on the market and by testing and reverse 
engineering products in the DOE test sample in support of the direct 
final rule. For each product class, DOE analyzed several efficiency 
levels and determined the incremental MPC at each of these levels. DOE 
initially reviewed data in DOE's Compliance Certification Database 
(``CCD'') to evaluate the range of efficiencies for consumer clothes 
dryers currently available on the market. As discussed in chapter 5 of 
the direct final rule TSD, non-ENERGY STAR-qualified products (i.e., 
generally units with lower-rated efficiencies) are typically tested 
using appendix D1, while ENERGY STAR-qualified products are required to 
be tested using appendix D2. As a result, DOE conducted testing on a 
representative sample of non-ENERGY STAR-qualified products using 
appendix D2 to determine appropriate initial incremental efficiency 
levels for each product class. DOE observed that while electronic 
controls are typically implemented with other design options in this 
analysis, the improved automatic termination precision offered by 
switching to electronic controls contributed significantly to an 
increase in efficiency. This efficiency gain informed the first 
incremental efficiency levels for most product classes and was noted 
simply as electronic controls in the design options listed in the 
tables later in this section. The design options associated with higher 
efficiency levels were subsequently distinguished according to specific 
design options DOE found manufacturers used to meet these higher 
efficiencies. As part of DOE's analysis, the maximum available 
efficiency level is the highest efficiency unit currently available on 
the market. DOE also defines a ``max-tech'' efficiency level to 
represent the maximum possible efficiency for a given product.
    For the vented gas compact product class, no units were available 
on the market at the time of the analysis whose rated value exceeded 
the baseline level. Given recent market trends, DOE does not have 
reason to expect manufacturers to re-introduce compact-size vented gas 
clothes dryers to the market, regardless of amendments to energy 
conservation standards. Accordingly, DOE did not consider any higher 
efficiency levels for this product class.
    In defining the incremental efficiency levels for the other product 
classes for this direct final rule, DOE considered comments it had 
received in response to the incremental efficiency levels proposed in 
the August 2022 NOPR, including several from commenters who support the 
Joint Agreement.
    The CA IOUs supported DOE's decision to adopt the updated max-tech 
levels as indicative of the growth and maturity of heat pump 
technologies for vented and ventless products. The CA IOUs further 
commented that adopting the max-tech levels sets a key precedent for 
subsequent DOE energy efficiency and non-DOE rulemakings to represent 
the true potential of a product class. (California IOUs, No. 50 at pp. 
4-5)
    AHAM and Whirlpool disagreed with DOE's tentative determination 
that the proposed standards in the August 2022 NOPR would allow for 
electromechanical controls. AHAM and Whirlpool commented that 
electronic controls are required to enable the technology options for 
the proposed TSL. Whirlpool further commented that electromechanical 
control dryers are not sophisticated enough to enable the other 
technology options that DOE described in the August 2022 NOPR analysis 
and therefore could not be used effectively with the appendix D2 test 
procedure. Whirlpool stated that DOE's NOPR analysis missed several key 
aspects where utility and performance could be lessened in order to 
meet the proposed standard levels. Whirlpool noted that the average CEF 
score of the five tested units in the vented electric standard product 
class with electromechanical

[[Page 18182]]

controls in the August 2022 NOPR analysis is 2.64 lb/kWh, over 30-
percent lower than the proposed standard. AHAM stated that 
electromechanical controls have consumer utility in that they are easy 
to use and reduce the overall costs associated with the product, and 
that requiring electronic controls would result in investment costs for 
manufacturers and increased purchase prices for consumers. AHAM 
requested that DOE retain electromechanical controls among a consumer's 
purchase options as, according to AHAM, they are a desirable feature 
for reliability, they provide reduced appliance cost among consumers, 
and their elimination from the market would likely cause consumers to 
postpone the purchase of new dryers, in turn increasing the total 
national energy consumption. Whirlpool stated concern regarding a 
forced regulatory phaseout of electromechanical controls because they 
are incorporated in a popular and affordable segment of consumer 
clothes dryers, and noted that although some electronic controls could 
be ``hidden'' from the consumer, there could be some lost utility from 
the easy and low-cost repairability of electromechanical control 
dryers. (AHAM, No. 46 at pp. 5, 10; Whirlpool, No. 53 at pp. 3-4)
    DOE is not aware of reliability issues associated with the 
implementation of electronic controls relative to electromechanical 
controls. However, DOE acknowledges that a transition from 
electromechanical controls to electronic controls may require 
manufacturer investment costs to redesign products and would likely 
increase purchase price for consumers, as captured in the incremental 
costs estimated and presented in this direct final rule analysis. Based 
on its analysis for this direct final rule, DOE believes that component 
costs associated with the implementation of electronic controls are 
lower than those estimated in the August 2022 NOPR analysis, which is 
reflected in the updated MPCs for the efficiency levels that entail a 
shift to electronic controls. These costs are reflected in the MPCs, 
which are the basis for the LCC and PBP analyses, in which consumer 
impacts related to increased purchase price and repair and maintenance 
costs are considered. Additionally, DOE reevaluated repair costs and 
accordingly implemented higher repair costs associated with electronic 
controls in this direct final rule analysis, consistent with 
Whirlpool's comments. See section IV.F of this document and chapter 8 
of the direct final rule TSD for additional details.
    Regarding the concern that clothes dryers equipped with 
electromechanical controls could not be tested under appendix D2, DOE 
notes that its test sample shows that requiring the use of the appendix 
D2 test procedure will not preclude the use of electromechanical 
controls. As discussed in chapter 5 of the direct final rule TSD, DOE 
tested baseline models with electromechanical controls under appendix 
D2, where available. For the ventless electric compact (240V) product 
class and the ventless electric combination washer-dryer product class, 
there were no baseline models identified with electromechanical 
controls; however, the same efficiency-level approach was taken to 
establish the efficiency-level structures for these product classes. 
The baseline efficiency levels in this direct final rule represent a 
minimally compliant, basic-construction consumer clothes dryer on the 
market, such as a dryer with electromechanical controls, and were set 
according to the lowest tested values under appendix D2 in each product 
class. As Whirlpool noted, the average CEF score of the five tested 
units in the vented electric standard product class with 
electromechanical controls was significantly lower than the proposed 
standard, further indicating the efficiency savings associated with a 
transition to a combination of electronic controls and higher design 
options. Regarding the concern that the proposed amended standards 
would require the implementation of electronic controls, DOE reiterates 
that although it expects that electronic controls are most likely to be 
used to achieve higher efficiency levels, and a review of ENERGY STAR-
qualified products suggests increased prevalent use of electronic 
controls, manufacturers are not required to implement these specific 
design options to meet amended standards. DOE therefore does not expect 
the amended standards to preclude electromechanical controls should 
manufacturers choose to implement them.
    Regarding AHAM and Whirlpool's comments that the required 
implementation of electronic controls to reach efficiency levels above 
the existing standard may result in a loss of consumer utility 
associated with the traditional user interface utilizing 
electromechanical controls, DOE's testing and analysis of models 
currently on the market confirms Whirlpool's statement that electronic 
controls may be ``hidden'' from consumers who prefer a more traditional 
user interface. This may be accomplished by implementing physical dials 
for consumer use that in turn manipulate the electronic controls in 
order to achieve the efficiency savings associated with electronic 
controls while providing the user experience of electromechanical 
controls. Therefore, even if electronic controls are utilized, DOE does 
not expect a loss in consumer utility associated with the use of 
electromechanical controls. DOE notes that AHAM recommended the 
proposed efficiency levels in the Joint Agreement on behalf of its 
members, including Whirlpool, in the Joint Agreement, which includes 
efficiency levels that can be achieved with the implementation of 
electronic controls.
    Whirlpool stated that there may be greater visibility and scrutiny 
of drying times associated with electronic control clothes dryers among 
consumers, as electromechanical control dryers do not display drying 
times. According to Whirlpool, consumers may believe they are losing 
control of their dryers in a way that results in additional energy 
consumption, and DOE should account for this possible behavioral shift 
and lost energy savings. (Whirlpool, No. 53 at p. 7)
    DOE is not aware of any data suggesting that the behavior of 
consumers of with clothes dryers utilizing electronic controls results 
in greater energy use than for consumers with clothes dryers utilizing 
electromechanical controls and notes that electronic controls are 
typically more efficient than electromechanical controls. As previously 
noted, manufacturers currently provide electronic controls that provide 
the experience of electromechanical controls through the use of dials 
which would avoid any loss in consumer utility.
    GEA stated that while the appendix D2 test procedure requires use 
of the ``normal'' or ''medium'' dryness setting for the clothes dryer 
test cycle, most labs, according to GEA, understand the ``optimum'' 
dryness setting to be the ``normal'' setting for appendix D2. GEA 
stated that it provides further clarity to consumers and test labs in 
the use and care manual for products with an ``optimum'' dryness 
setting by specifying that optimum is the dryness setting to use for 
most clothes when running the ``cottons'' cycle (the drying cycle 
recommended for certain consumer clothes dryers manufactured by GEA for 
drying cotton). Therefore, based on the cycle settings provided by the 
additional test information DOE published on October 13, 2022, and 
information provided by Guidehouse to GEA under a non-disclosure 
agreement,

[[Page 18183]]

GEA stated that DOE incorrectly tested two models in its test sample 
and urged DOE to either rerun its testing, exclude the models in 
question from its analysis, or accept the data provided by GEA and 
adjust its savings model. (GEA, No. 49 at pp. 2-3)
    DOE notes that the baseline units GEA referenced are certified 
under appendix D1, and although these units were not originally 
intended to be tested under the appendix D2 test procedure, DOE tested 
them using the appropriate cycle settings under the appendix D2 test 
procedure to support the engineering analysis. These settings were 
different than the ``optimum'' dryness setting specified in the use and 
care manual for these particular units. Although GEA referred to 
specific cycle settings for consumer use, DOE notes that this 
instruction for cycle settings does not supersede the requirements of 
the appendix D2 test procedure. Additionally, DOE notes that the test 
cycle settings used were within the range anticipated and not expressly 
warned against by the owner's manual or use and care manual. Therefore, 
DOE maintains that the correct cycle settings were used to test the 
units in question.
    Whirlpool stated that DOE should have presented the cycle times 
before and after wrinkle prevention mode was enabled for models in the 
test sample that had wrinkle prevention mode on by default. Whirlpool 
further stated that models reported in the data had extremely long 
cycle times, between 88 and 319 minutes, but that such times were 
distorted due to testing with wrinkle protection mode enabled. 
Additionally, Whirlpool stated that testing of consumer clothes dryers 
with wrinkle prevention mode enabled by default may have distorted some 
of the tested settings and the resulting CEF scores because wrinkle 
prevention results in additional cycle time of continuous tumbling 
after the heating element has been turned off. Whirlpool stated that, 
this results in an energy penalty as the additional cycle time 
potentially allows for moisture absorption in the test load to the 
point of failing to meet the required FMC of 2 percent, and therefore a 
retest is required using the highest dryness level setting associated 
with more energy consumption and thus a lower average measured CEF. 
Whirlpool further stated that wrinkle prevention mode does not produce 
an accurate comparison of average cycle times and CEF scores of these 
dryers compared to other dryers that do not have wrinkle prevention 
modes enabled by default, and DOE should have also recorded the CEF 
scores, FMC, and drying times of these models before they were allowed 
to enter wrinkle prevention mode. Whirlpool stated that this data 
should have been used to inform comparisons between dryers and the 
development of baseline efficiency levels. Whirlpool stated that if 
these dryers were designed to the appendix D2 test procedure, wrinkle 
prevention mode would likely not have been enabled by default. 
(Whirlpool, No. 53 at pp. 9-10)
    In the August 2013 TP Final Rule, DOE clarified that if a clothes 
dryer is equipped with a wrinkle prevention mode that is activated by 
default in the as-shipped position, the cycle shall be considered 
complete after the end of the wrinkle prevention mode. 76 FR 49607, 
49623-49624. Although wrinkle prevention mode may have been disabled 
had the test units been designed for appendix D2 testing, DOE stated 
previously that accurate testing of existing baseline units according 
to the appendix D2 test procedure was essential for the analysis, 
including the use of optional cycle settings that are enabled by 
default and that do not affect the program, temperature, or dryness 
settings. The test procedure in appendix D2 therefore requires that 
testing include wrinkle prevention mode if it is enabled by default. 
DOE maintains, as it was unable to predict or assume the cycle settings 
Whirlpool would have selected had the test units been designed for 
appendix D2 testing, that the test units in question were properly 
tested in accordance with appendix D2 using the correct cycle settings 
consistent with the DOE test procedure.
    Chapter 5 of the direct final rule TSD discusses the incremental 
efficiency levels for each of the product classes in this analysis. The 
revised CEF<INF>D2</INF> efficiency levels for each product class are 
shown below in Table IV.5 through Table IV.10, along with the current 
energy conservation standards in CEF<INF>D1</INF> for comparison. As 
discussed in section IV.C.1.a of this document, the baseline 
CEF<INF>D2</INF> values estimated for the preliminary analysis are 
lower than the current CEF<INF>D1</INF> values in the energy 
conservation standards due to the differences in testing between 
appendix D1 and appendix D2.

    \44\ DOE is aware of consumer clothes dryers in the electric 
standard product class that perform at higher efficiencies than the 
proposed max-tech level, but those models are not representative of 
the typical capacity in the electric standard product class. 
Therefore, based on the certified performance of those models and 
additional investigative testing, DOE determined a representative 
max-tech efficiency for the electric standard product class that 
reflects an appropriate, representative unit capacity. See chapter 5 
of the final rule TSD for more information.

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, and the availability and timeliness of purchasing the product 
on the market. The cost approaches are summarized as follows:
    <bullet> 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.
    <bullet> 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.
    <bullet> 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 present case, DOE conducted the analysis using physical 
product teardowns to determine the baseline MPC for each product class 
as outlined in chapter 5 of the direct final rule TSD. DOE developed 
the cost-efficiency relationships for each product class as discussed 
in section IV.C.3 of this document. DOE developed incremental MPCs 
based on product teardowns and manufacturing cost modeling of the 
expected design changes at each efficiency level. DOE observed that the 
basic product designs of vented electric and vented gas clothes dryers 
are similar except for the heating system. DOE also observed that the 
technology designs of standard-size and compact-size consumer clothes 
dryers are similar as well, simply scaled in size. As a result, in the 
absence of models available on the market at certain efficiency levels 
for certain product classes, DOE estimated the incremental MPC for 
these based on the same design changes observed for the electric 
standard product class. DOE updated the cost-efficiency analysis from 
the preliminary analysis by updating the costs of raw materials and 
purchased components, as well as updating costs for manufacturing 
equipment, labor, and depreciation. DOE also used information from the 
teardown of units in the updated test sample to inform updates to the 
cost-efficiency analysis. Not all units in the updated test sample were 
torn down; DOE focused on units recently introduced in the market, 
units with unique configuration, and units with technologies that were 
not available at the time of the preliminary analysis to better inform 
the costs associated with particular product classes and design 
options.
    The resulting bill of materials provides the basis for the MPC 
estimates in this direct final rule. The baseline MPCs for each 
consumer clothes dryer product class are listed in Table IV.11, with 
all costs presented in 2022 dollars.

(vii) Ventless Electric, Combination Washer-Dryer.......          611.19
------------------------------------------------------------------------

    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 consumer clothes dryers.\46\ See 
section IV.J.2.d of this document and chapter 12 of the direct final 
rule TSD for additional information on the manufacturer markup.

3. Cost-Efficiency Results
    The results of the engineering analysis are presented as cost-
efficiency data for each of the efficiency levels for each of the 
product classes that were analyzed, as well as those extrapolated from 
a product class with similar features. DOE developed estimates of MPCs 
for each unit in the teardown sample to develop a comprehensive set of 
incremental MPCs (i.e., the additional costs manufacturers would likely 
incur by producing consumer clothes dryers at each efficiency level 
compared to the baseline).
    The resulting incremental MPCs from this analysis are provided in 
Table IV.12 through Table IV.17. See chapter 5 of the direct final rule 
TSD for additional detail on the engineering analysis.

D. Markups Analysis

    The markups analysis develops appropriate markups (e.g., 
manufacturer markups, retailer markups, distributor 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 profit margin.
    DOE considered two distribution channels through which consumer 
clothes dryers move from manufacturers to consumers. The majority of 
consumer clothes dryer sales go through the direct retailer channel, in 
which manufacturers sell the products directly to retailers, who then 
sell to consumers. This direct retailer channel accounts for 90 percent 
of the consumer clothes dryer market. The rest of the market goes 
through a separate new construction distribution channel, in which 
manufacturers sell the products to wholesalers, who in turn sell the 
products to general contractors, then to consumers. The main parties in 
the post-manufacturer distribution channels are retailers, wholesalers, 
and contractors.
    DOE developed baseline and incremental markups for each actor in 
the distribution channels. 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.\47\
---------------------------------------------------------------------------

    \47\ Because the projected price of standards-compliant products 
is typically higher than the price of baseline products, using the 
same markup for the incremental cost and the baseline cost would 
result in higher per-unit operating profit. While such an outcome is 
possible, DOE maintains that in markets that are reasonably 
competitive it is unlikely that standards would lead to a 
sustainable increase in profitability in the long run.
---------------------------------------------------------------------------

    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; \48\ the 2017 Annual 
Wholesale Trade Survey for ``household appliances, and electrical and 
electronic goods merchant wholesalers'' to estimate wholesaler markups; 
\49\ and the 2017 Economic Census for the residential construction 
sector to derive general contractor markups.\50\

E. Energy Use Analysis

    The purpose of the energy use analysis is to determine the annual 
energy consumption of consumer clothes dryers at different efficiencies 
in representative U.S. single-family homes, multifamily residences, and 
mobile homes and to assess the energy savings potential of increased 
consumer clothes dryer efficiency. The energy use analysis estimates 
the range of energy use of consumer clothes dryers 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.
    In conducting the energy use analysis for this direct final rule, 
DOE considered comments it had received in response to the proposed 
analysis in the August 2022 NOPR. DOE received a comment from AHAM 
regarding the number of annual use cycles in the August 2022 NOPR 
energy use analysis. AHAM requested that DOE review the 2020 
Residential Energy Consumption Survey (``2020 RECS'') data \51\ and 
adjust the annual number of cycles accordingly. AHAM stated that it 
previously commented that RECS 2015 suggested an annual number of 
cycles of 236 as opposed to the 283 cycles in the current test 
procedure, which is consistent with the observation that clothes washer 
cycles have decreased in number to 234 cycles per year using the 2015 
RECS. According to AHAM, it does not make sense for clothes washer 
cycles to decrease and clothes dryer cycles to increase or even stay 
the same. AHAM suggested that based on the 2020 RECS, the annual number 
of cycles should be 209. (AHAM, No. 46 at p. 12)

available at <a href="http://www.eia.gov/consumption/residential/data/2020/">www.eia.gov/consumption/residential/data/2020/</a>.
---------------------------------------------------------------------------

    In the August 2022 NOPR analysis, DOE used data from the EIA's 2015 
Residential Energy Consumption Survey (``2015 RECS'') to establish a 
reasonable range of energy consumption in the field for consumer 
clothes dryers. DOE noted that the microdata for the 2020 RECS was not 
available at the time the NOPR analysis was conducted but stated that 
it would update the underlying data to 2020 RECS if it was available 
prior to the final rule. 87 FR 51762. DOE is aware that the 2020 RECS 
has been published.\52\ This survey collected data from 18,496 housing 
units and was designed by EIA to represent the household population in 
the United States. Therefore, DOE has integrated this data into its 
analysis for the direct final rule concerning households using clothes 
dryers.

---------------------------------------------------------------------------

    DOE divided the sample of households into four subsamples for the 
product classes being analyzed:

[[Page 18188]]

standard or compact consumer clothes dryers using electricity or 
natural gas as the dryer fuel. For compact consumer clothes dryers, DOE 
developed a subsample consisting of households with an electric or gas 
clothes dryer in multifamily buildings, manufactured homes, and single-
family homes with less than 1,000 square feet and no garage or 
basement, since these products are most likely to be found in these 
housing types.
    The energy use analysis requires DOE to establish a range of total 
annual usage (number of cycles) in order to estimate annual energy 
consumption by a clothes dryer. DOE estimated the number of clothes 
dryer cycles per year for each sample household using data from the 
2020 RECS on the number of laundry loads washed (clothes washer cycles) 
per week and the frequency of clothes dryer use. The average annual 
energy consumption was then calculated, reflecting an average annual 
sample-weighted usage of 213 cycles per year.
    For each considered efficiency level, DOE derived the field energy 
use by separately estimating the active mode and standby mode energy 
use and then adding them together. The per-cycle active mode energy 
consumption was estimated using the DOE clothes dryer test procedure at 
appendix D2. It was then back calculated from the test procedure 
results by dividing the weight (lb) of clothes dried per-cycle (i.e., 
8.45 lb for standard and 3 lb for compact consumer clothes dryers) by 
the CEF<INF>D2</INF> (lb/kWh) and subtracting standby power. DOE 
adjusted the test procedure energy use to reflect field conditions by 
making an adjustment for clothes dryer load weight and moisture removal 
factor. Chapter 7 of the direct final rule TSD provides more detail 
about these calculations.
    DOE also considered the impact of clothes dryer operation on home 
heating and cooling loads, given that a clothes dryer releases heat to 
the surrounding environment. If the clothes dryer is located indoors, 
its use will tend to slightly reduce the heating load during the 
heating season and slightly increase the cooling load during the 
cooling season. To calculate this impact, DOE first estimated whether 
the clothes dryer in a RECS sample home is located in conditioned space 
(referred to as ``indoors'') or in unconditioned space (e.g., garages, 
unconditioned basements, outdoor utility closets, or attics). Based on 
the 2020 RECS and the 2019 American Housing Survey (``AHS''),\53\ DOE 
assumed that 50 percent of vented standard electric and gas consumer 
clothes dryers are located indoors, while 100 percent of compact and 
ventless consumer clothes dryers are located indoors. For these 
installations, DOE used the results from a European Union study about 
the impacts of consumer clothes dryers on home heating and cooling 
loads to determine the appropriate factor to apply to the total clothes 
dryer energy use.\54\ This study reported that for vented consumer 
clothes dryers, there is a factor of negative 3 to 9 percent (average 3 
percent), and for ventless consumer clothes dryers there is a factor of 
positive 7 to 15 percent (average 11 percent).\55\ This effect is 
likely to be approximately the same for all of the considered 
efficiency levels because the amount of air passing through the clothes 
dryer does not vary.

energy use analysis for consumer clothes dryers.

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 
consumer clothes dryers. 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:
    <bullet> 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.
    <bullet> 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 the LCC in the no-new-standards case, which reflects the 
estimated efficiency distribution of consumer clothes dryers 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. As stated previously, DOE developed household samples 
from the 2020 RECS. For each sample household, DOE determined the 
energy consumption for the consumer clothes dryers and the appropriate 
energy price. By developing a representative sample of households, the 
analysis captured the variability in energy consumption and energy 
prices associated with the use of consumer clothes dryers.
    Inputs to the calculation of total installed cost include the cost 
of the product--which includes MPCs, manufacturer markups, retailer and 
distributor 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 consumer clothes dryer user samples. 
For this rulemaking, the Monte Carlo approach is implemented in MS 
Excel together with the Crystal Ball\TM\ add-on.\56\ The model 
calculated the LCC for products

[[Page 18189]]

at each efficiency level for 10,000 housing units 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 consumer clothes dryers as if each 
were to purchase a new product in the first year of required compliance 
with new or amended standards. New and amended standards apply to 
consumer clothes dryers 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 consumer clothes dryers for all the TSLs other 
than TSL 3. For TSL 3, DOE used 2028 as the first year of compliance 
for all product classes as specified for the Recommended TSL in the 
Joint Agreement.

* Not used for PBP calculation. References for the data sources
  mentioned in this table are provided in the following sections or in
  chapter 8 of the direct final rule TSD.

    For this direct final rule, DOE considered comments it had received 
regarding the methodology for evaluating consumer economic impact that 
were submitted in response to the August 2022 NOPR. The approach used 
for this direct final rule is largely the same approach DOE had used 
for the August 2022 NOPR analysis.
    In response to the August 2022 NOPR AHAM recommended that DOE 
modify the way consumer economic impact is analyzed and look at the 
probability that individual consumers will benefit from standards 
rather than whether the aggregate benefit is positive. (AHAM, No. 46 at 
p. 13)
    In the LCC analysis, DOE notes that it does estimate the impact of 
potential standards on individual consumers in the household sample and 
considers the share of consumers that would benefit from a standard as 
part of its evaluation regarding whether particular standards are 
economically justified.
1. 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. To derive the learning rate parameter for consumer clothes 
dryers, DOE obtained historical Producer Price Index (``PPI'') data 
from the Bureau of Labor Statistics (``BLS'') for ``household laundry 
equipment'' between 1947 and 2016 and ``major household appliance: 
primary products'' between 2016 and 2022 to form a time series price 
index representing household laundry equipment from 1947 to 2022.\57\ 
Inflation-adjusted price indices were calculated by dividing the PPI 
series by the gross domestic product index from the Bureau of Economic 
Analysis for the same years. Using this data from 1947 to 2022, the 
estimated learning rate (defined as the fractional reduction in price 
from each doubling of cumulative production) is 17.2 percent.

    For this direct final rule, DOE considered comments it had received 
regarding the methodology for calculating consumer product costs that 
were submitted in response to the August 2022 NOPR. The approach used

for this direct final rule is largely the same approach DOE had used 
for the August 2022 NOPR analysis.
    In response to the August 2022 NOPR, AHAM stated that DOE's pricing 
estimates are incorrect because currently, publicly available retail 
market prices for the lowest-priced units (many of which are equipped 
with electromechanical controls) are approximately $400, and DOE's 
estimate for a baseline standard electric unit is $607. (AHAM, No. 46 
at pp. 5-6, 8)
    Whirlpool stated that DOE does not consider retail prices for 
models actually being sold in the market today that meet varying 
efficiency levels and actually utilize technology options needed to 
meet TSL 3. Whirlpool commented that retail price differences between 
$200 and $300 may be a better reflection of the expected price premiums 
for consumers from amended standards than DOE's analysis and 
methodology. (Whirlpool, No. 53 at p. 7)
    In response, DOE notes that the actual retail price differences 
between a baseline and higher efficiency level currently on the market 
may include the price for other premium features in addition to 
engineering designs relating to efficiency. Additionally, retail prices 
reflect economies of scale in production as well as marketing 
strategies and profit margins of manufacturers and retailers. DOE 
maintains that its traditional approach, which has been subject to peer 
review, is better able to identify the incremental costs that are only 
connected to higher efficiency. Furthermore, in this direct final rule 
analysis, DOE leveraged web scraping to gather data on clothes dryer 
models available on the market from January to March 2023. The data was 
collected from major retail outlets, including Best Buy, Lowe's, and AJ 
Madison. DOE found that the lowest-priced baseline model cost $630. DOE 
therefore concluded that its baseline estimate for a standard electric 
unit is reasonable for this dir
