I. Introduction
A. Authority
The Energy Policy and Conservation Act, 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 C \2\ of EPCA established the Energy Conservation
Program for Certain Industrial Equipment. This equipment includes walk-
in coolers and walk-in freezers, the subject of this document. (42
U.S.C. 6311(1)(G))
---------------------------------------------------------------------------
\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 C was redesignated Part A-1.
---------------------------------------------------------------------------
EPCA prescribes a set of basic requirements for walk-ins. First,
all walk-in doors narrower than 3 feet 9 inches and shorter than 7 feet
must have automatic door closers that firmly close all walk-in doors
that have been closed to within 1 inch of full closure. All walk-ins
must also have strip doors, spring hinged doors, or other methods of
minimizing infiltration when doors are open. Additionally, walk-ins
must contain wall, ceiling, and door insulation of at least R-25 for
coolers and R-32 for freezers, excluding glazed portions of doors and
structural members, and floor insulation of at least R-28 for freezers.
Walk-in evaporator fan motors of under 1 horsepower (``hp'') and less
than 460 volts must be electronically commutated motors (brushless
direct current motors) or three-phase motors, and walk-in condenser fan
motors of under 1 horsepower must use permanent split capacitor motors,
electronically commutated motors, or three-phase motors. Interior light
sources must have an efficacy of 40 lumens per watt or more, including
any ballast losses; less-efficacious lights may only be used in
conjunction with a timer or device that turns off the lights within 15
minutes of when the walk-in is unoccupied. (See 42 U.S.C. 6313(f)(1))
Additionally, EPCA requires that walk-in freezers with transparent
reach-in doors and windows must have triple-pane glass with either
heat-reflective treated glass or gas fill. Transparent walk-in cooler
doors and windows must have either double-pane glass with heat-
reflective treated glass and gas fill or triple-pane glass with heat-
reflective treated glass or gas fill. (42 U.S.C. 6313(f)(3)(A)-(B))
EPCA also prescribes specific anti-sweat heater-related requirements:
Walk-ins without anti-sweat heater controls must have a heater power
draw of no more than 7.1 or 3.0 watts per square foot of door opening
for freezers and coolers, respectively. If walk-ins have a heater power
draw of more than 7.1 or 3.0 watts per square foot of door opening for
freezers and coolers, respectively, then the walk-in must have anti-
sweat heater controls that reduce the energy use of the heater in a
quantity corresponding to the relative humidity of the air outside the
door or to the condensation on the inner glass pane. See 42 U.S.C.
6313(f)(3)(C)-(D).
Additionally, EPCA prescribed two cycles of WICF-specific
rulemakings; the first to establish performance-based standards that
achieve the maximum improvement in energy that the Secretary determines
is technologically feasible and economically justified, and the second
to determine whether to amend those standards. (42 U.S.C. 6313(f)(4)
and (5)) DOE has satisfied the first of these requirements. See 79 FR
32050 (June 3, 2014) (establishing WICF performance standards) and 82
FR 31808 (July 10, 2017) (addressing prior rulemaking errors by
amending certain refrigeration system class standards). This document
addresses the second cycle of rulemaking.
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 notification of determination that standards for
the equipment do not need to be amended, or a notice of proposed
rulemaking (``NOPR'') including new proposed energy conservation
standards (proceeding to a final rule, as appropriate). (42 U.S.C.
6316(a); 42 U.S.C. 6295(m)(1)) Not later than three years after
issuance of a final determination not to amend standards, DOE must
publish either a notice of determination that standards for the
equipment 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. 6316(a); 42 U.S.C. 6295(m)(3)(B))
Under EPCA, any new or amended energy conservation standard must be
designed to achieve the maximum improvement in energy efficiency that
DOE determines is technologically feasible and economically justified.
(42 U.S.C. 6316(a); 42 U.S.C. 6295(o)(2)(A)) Furthermore, the new or
amended standard must result in a significant conservation of energy.
(42 U.S.C. 6316(a); 42 U.S.C. 6295(o)(3)(B))
DOE is publishing this Preliminary Analysis to collect data and
information to inform its decision consistent with its obligations
under EPCA.
B. Rulemaking Process
DOE must follow specific statutory criteria for prescribing new or
amended standards for covered equipment, including walk-ins. As noted,
EPCA requires that any new or amended energy conservation standard
prescribed by the Secretary of Energy (``Secretary'') be designed to
achieve the maximum improvement in energy efficiency (or water
efficiency for certain products specified by EPCA) that is
technologically feasible and
[[Page 39010]]
economically justified. (42 U.S.C. 6316(a); 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. 6316(a); 42 U.S.C.
6295(o)(3))
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.\3\ For
example, the United States has now rejoined the Paris Agreement on
February 19, 2021. As part of that agreement, the United States has
committed to reducing greenhouse gas (``GHG'') emissions in order to
limit the rise in mean global temperature.\4\ As such, energy savings
that reduce GHG emission have taken on greater importance.
Additionally, some covered products and equipment have most of their
energy consumption occur during periods of peak energy demand. The
impacts of these products on the energy infrastructure can be more
pronounced than products with relatively constant demand. In evaluating
the significance of energy savings, DOE considers differences in
primary energy and FFC effects for different covered products and
equipment when determining whether energy savings are significant.
Primary energy and FFC effects include the energy consumed in
electricity production (depending on load shape), in distribution and
transmission, and in extracting, processing, and transporting primary
fuels (i.e., coal, natural gas, petroleum fuels), and thus present a
more complete picture of the impacts of energy conservation standards.
Accordingly, DOE evaluates the significance of energy savings on a
case-by-case basis.

in New or Revised Energy Conservation Standards and Test Procedures
for Consumer Products and Commercial/Industrial Equipment, 86 FR
70892, 70901 (Dec. 13, 2021).
\4\ See Executive Order 14008, 86 FR 7619 (Feb. 1, 2021)
(``Tackling the Climate Crisis at Home and Abroad'').
---------------------------------------------------------------------------
DOE has initially determined the energy savings for the candidate
standard levels evaluated in this preliminary analysis rulemaking are
``significant'' within the meaning of 42 U.S.C. 6295(o)(3)(B).
To determine whether a standard is economically justified, EPCA
requires that DOE determine whether the benefits of the standard exceed
its burdens by considering, to the greatest extent practicable, the
following seven factors:
(1) The economic impact of the standard on the 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
products likely to result from the standard;
(5) The impact of any lessening of competition, as determined in
writing by the Attorney General, that is likely to result from the
standard;
(6) The need for national energy and water conservation; and
(7) Other factors the Secretary of Energy (Secretary) considers
relevant.
(42 U.S.C. 6316(a); 42 U.S.C. 6295(o)(2)(B)(i)(I)-(VII))
DOE fulfills these and other applicable requirements by conducting
a series of analyses throughout the rulemaking process. Table I.1 shows
the individual analyses that are performed to satisfy each of the
requirements within EPCA.
---------------------------------------------------------------------------
\5\ On March 16, 2022, the Fifth Circuit Court of Appeals (No.
22-30087) granted the Federal government's emergency motion for stay
pending appeal of the February 11, 2022, preliminary injunction
issued in Louisiana v. Biden, No. 21-cv-1074-JDC-KK (W.D. La.). As a
result of the Fifth Circuit's order, the preliminary injunction is
no longer in effect, pending resolution of the Federal government's
appeal of that injunction or a further court order. Among other
things, the preliminary injunction enjoined the defendants in that
case from ``adopting, employing, treating as binding, or relying
upon'' the interim estimates of the social cost of greenhouse
gases--which were issued by the Interagency Working Group on the
Social Cost of Greenhouse Gases on February 26, 2021--to monetize
the benefits of reducing greenhouse gas emissions. In the absence of
further intervening court orders, DOE will revert to its approach
prior to the injunction and present monetized benefits where
appropriate and permissible under law.

[[Page 39011]]
Further, EPCA establishes a rebuttable presumption that a standard
is economically justified if the Secretary finds that the additional
cost to the consumer of purchasing equipment 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. 6316(a); 42 U.S.C. 6295(o)(2)(B)(iii))
EPCA 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
equipment. (42 U.S.C. 6316(a); 42 U.S.C. 6295(o)(1)) Also, the
Secretary may not prescribe an amended or new standard if interested
persons have established by a preponderance of the evidence that the
standard is likely to result in the unavailability in the United States
in any covered equipment 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. 6316(a); 42 U.S.C. 6295(o)(4))
Additionally, EPCA specifies requirements when promulgating an
energy conservation standard for covered equipment that has two or more
subcategories. DOE must specify a different standard level for a type
or class of equipment 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 equipment within
such type (or class); or (B) have a capacity or other performance-
related feature which other equipment within such type (or class) do
not have and such feature justifies a higher or lower standard. (42
U.S.C. 6316(a); 42 U.S.C. 6295(q)(1)) In determining whether a
performance-related feature justifies a different standard for a group
of products, DOE must consider such factors as the utility to the
consumer of the feature and other factors DOE deems appropriate. Id.
Any rule prescribing such a standard must include an explanation of the
basis on which such higher or lower level was established. (42 U.S.C.
6316(a); 42 U.S.C. 6295(q)(2))
Before proposing a standard, DOE typically seeks public input on
the analytical framework, models, and tools that DOE intends to use to
evaluate standards for the equipment at issue and the results of
preliminary analyses DOE performed for the product.
DOE is examining whether to amend the current standards pursuant to
its obligations under EPCA. This notification announces the
availability of the preliminary TSD, which details the preliminary
analyses and summarizes the preliminary results of DOE's analyses. In
addition, DOE is announcing a public meeting to solicit feedback from
interested parties on its analytical framework, models, and preliminary
results.
C. Deviation From Appendix A
In accordance with section 3(a) of 10 CFR part 430, subpart C,
appendix A (``appendix A''), applicable to walk-ins under 10 CFR 431.4,
DOE notes that it is deviating from the provision in appendix A
regarding the pre-NOPR stages for an energy conservation standards
rulemaking. Section 6(a)(2) of appendix A states that if the Department
determines it is appropriate to proceed with a rulemaking (after
initiating the rulemaking process through an early assessment), the
preliminary stages of a rulemaking to issue or amend an energy
conservation standard that DOE will undertake will be a framework
document and preliminary analysis, or an advance notice of proposed
rulemaking (``ANOPR''). DOE is opting to deviate from this provision by
publishing a preliminary analysis without a framework document. A
framework document is intended to introduce and summarize the various
analyses DOE conducts during the rulemaking process and requests
initial feedback from interested parties. As discussed further in the
following section, prior to this notification of the preliminary
analysis, DOE issued an early assessment request for information on
July 16, 2021 (``July 2021 RFI'') in which DOE identified and sought
data, information, and comment to evaluate whether the existing energy
conservation standards for walk-ins should be amended. 86 FR 37687,
37689. DOE provided a 30-day comment period for the RFI. DOE intends to
rely on substantively the same analytical methods as those used in the
most recent rulemakings for walk-ins, making publication of a framework
document largely redundant with the July 2021 RFI. As such, DOE is not
publishing a framework document.
DOE notes that it is also deviating from the provision in appendix
A regarding the length of comment periods for the pre-NOPR stages for
an energy conservation standards rulemaking. Section 6(d)(2) of
appendix A specifies that the length of the public comment period for
pre-NOPR rulemaking documents will not be less than 75 calendar days.
For the preliminary analysis, DOE has opted instead to provide a 60-day
comment period. As stated, DOE requested comment in the July 2021 RFI
on the analysis conducted in support of the last energy conservation
standard rulemaking for WICFs. Given that the analysis will largely
remain the same, and in light of the 30-day comment period DOE has
already provided with its July 2021 RFI, DOE has determined that a 60-
day comment period is sufficient to enable interested parties to review
the tentative methodologies and accompanying analysis to develop
meaningful comments in response to the preliminary TSD.
II. Background
A. Current Standards
In a final rule published on June 3, 2014 (``June 2014 Final
Rule''), DOE adopted the current energy conservation standards for
walk-in doors, panels, and medium-temperature dedicated condensing
systems manufactured on and after June 5, 2017. 79 FR 32050. In the
June 2014 Final Rule, DOE also adopted standards for other classes of
refrigeration systems; however, after publication of the June 2014
Final Rule, the Air-Conditioning, Heating and Refrigeration Institute
(``AHRI'') and Lennox International, Inc. (``Lennox''), a manufacturer
of walk-in refrigeration systems, filed petitions for review of DOE's
final rule and DOE's subsequent denial of a petition for
reconsideration of the rule (79 FR 59090 (October 1, 2014)) with the
United States Court of Appeals for the Fifth Circuit. Lennox Int'l v.
Dep't of Energy, Case No. 14-60535 (5th Cir.). As a result of this
litigation, a settlement agreement was reached to address, and a
controlling order from the Fifth Circuit vacated, standards for six of
the refrigeration system equipment classes--the two energy conservation
standards applicable to multiplex condensing refrigeration systems
(subsequently re-named as ``unit coolers'') operating at medium and low
temperatures and the four energy conservation standards applicable to
dedicated condensing refrigeration systems operating at low
temperatures.\6\ After the Fifth Circuit issued its order, DOE
established a Working Group to negotiate energy
[[Page 39012]]
conservation standards to replace the six vacated standards. 80 FR
46521 (August 5, 2015). The Working Group assembled its recommendations
into a Term Sheet (See Docket EERE-2015-BT-STD-0016-0056) that was
presented to, and approved by, the Appliance Standards and Rulemaking
Federal Advisory Committee (``ASRAC'') on December 18, 2015. (EERE-
2015-BT-STD-0016-0055 at p. 11)
---------------------------------------------------------------------------
\6\ The thirteen other standards established in the June 2014
Final Rule (i.e., the four standards applicable to dedicated
condensing refrigeration systems operating at medium-temperatures;
the three standards applicable to panels; and the six standards
applicable to doors) were not vacated.
---------------------------------------------------------------------------
In a final rule published on July 10, 2017 (``July 2017 Final
Rule''), DOE published a final rule adopting current energy
conservation standards for the six classes of walk-in refrigeration
systems for which the prior standards were vacated--specifically, unit

B. Current Process
As noted earlier, DOE published an RFI to initiate an early
assessment review to determine whether any new or amended standards
would satisfy the relevant requirements of EPCA for a new or amended
energy conservation standard for walk-ins and to solicit relevant
information from the public. 86 FR 37687. Through the RFI, DOE sought
data and information to, among other things, help the agency determine
whether DOE should propose a ``no new standard'' determination because
a more stringent standard: (1) would not result in a significant
savings of energy; (2) is not technologically feasible; (3) is not
economically justified; or (4) any combination of foregoing. Id.
Comments received to date as part of the current process have
helped DOE identify and resolve issues related to the preliminary
analyses. Chapter 2 of the preliminary TSD summarizes and addresses the
comments received.
III. Summary of the Analyses Performed by DOE
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 general characteristics 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 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
[[Page 39013]]
could improve the energy efficiency of the product.
See chapter 3 of the preliminary TSD for further discussion of the
market and technology assessment.
B. Screening Analysis
DOE uses the following five 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 working prototypes will not
be considered further.
(2) Practicability to manufacture, install, and service. If it is
determined that mass production and reliable installation and servicing
of a technology in commercial products 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 or product availability. If it is
determined that a technology would have a significant adverse impact on
the utility of the product for significant subgroups of consumers or
would 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) Adverse impacts on health or safety. 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 design option
utilizes proprietary technology that represents a unique pathway to
achieving a given efficiency level, that technology 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).
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.
See chapter 4 of the preliminary TSD for further discussion of the
screening analysis.
C. Engineering Analysis
The purpose of the engineering analysis is to establish the
relationship between the efficiency and cost of walk-ins. 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 equipment cost at each efficiency level (i.e., the
``cost analysis''). In determining the performance of higher-efficiency
equipment, DOE considers technologies and design option combinations
not eliminated by the screening analysis. For each equipment class, DOE
estimates the manufacturer production cost (``MPC'') for the baseline
as well as higher efficiency levels. 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).
DOE converts the MPC to the manufacturer selling price (``MSP'') by
applying a manufacturer markup. The MSP is the price the manufacturer
charges its first customer, when selling into the equipment
distribution channels. The manufacturer markup accounts for
manufacturer non-production costs and profit margin. DOE developed the
manufacturer markup by examining publicly available financial
information for manufacturers of the covered product.
See Chapter 5 of the preliminary TSD for additional detail on the
engineering analysis.
D. Markups Analysis
The markups analysis develops appropriate markups (e.g., retailer
markups, distributor markups, contractor markups) in the distribution
chain and sales taxes to convert 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 equipment to cover business costs and profit
margin.
DOE developed baseline and incremental markups for each agent in
the distribution chain. Baseline markups are applied to the price of
products with baseline efficiency, while incremental markups are
applied to the difference in price between baseline and higher-
efficiency models (the incremental cost increase). The incremental
markup is typically less than the baseline markup and is designed to
maintain similar per-unit operating profit before and after new or
amended standards.\7\
---------------------------------------------------------------------------
\7\ 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.
---------------------------------------------------------------------------
Chapter 6 of the preliminary TSD provides details on DOE's
development of markups for walk-ins.
E. Energy Use Analysis
The purpose of the energy use analysis is to determine the annual
energy consumption of walk-ins at different efficiencies in
representative U.S. commercial buildings and to assess the energy
savings potential of increased walk-in efficiency. The energy use
analysis estimates the range of energy use of walk-ins 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.
Chapter 7 of the preliminary TSD addresses the energy use analysis.
F. Life-Cycle Cost and Payback Period Analyses
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
equipment over the life of that product, consisting of total installed
cost (MSP, 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 equipment 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.
Chapter 8 of the preliminary TSD addresses the LCC and PBP
analyses.
G. National Impact Analysis
The NIA estimates the national energy savings (``NES'') and the net
present value (``NPV'') of total consumer costs and savings expected to
result from amended standards at specific efficiency
[[Page 39014]]
levels (referred to as candidate standard levels).\8\ DOE calculates
the NES and NPV for the potential standard levels considered based on
projections of annual equipment shipments, along with the annual energy
consumption and total installed cost data from the energy use and LCC
analyses. For the present analysis, DOE projected the energy savings,
operating cost savings, equipment costs, and NPV of consumer benefits
over the lifetime of walk-ins sold from 2027 through 2056.
---------------------------------------------------------------------------
\8\ The NIA accounts for impacts in the 50 states and U.S.
territories.
---------------------------------------------------------------------------
DOE evaluates the impacts of new or amended standards by comparing
a case without such standards with standards-case projections (``no-
new-standards case''). The no-new-standards case characterizes energy
use and consumer costs for each equipment class in the absence of new
or amended energy conservation standards. For this projection, DOE
considers historical trends in efficiency and various forces that are
likely to affect the mix of efficiencies over time. DOE compares the
no-new-standards case with projections characterizing the market for
each equipment class if DOE adopted new or amended standards at
specific energy efficiency levels for that class. For each efficiency
level, DOE considers how a given standard would likely affect the
market shares of equipment with efficiencies greater than the standard.
DOE uses a spreadsheet model to calculate the energy savings and
the national consumer costs and savings from each efficiency level.
Interested parties can review DOE's analyses by changing various input
quantities within the spreadsheet. The NIA spreadsheet model uses
typical values (as opposed to probability distributions) as inputs.
Critical inputs to this analysis include shipments projections,
estimated equipment lifetimes, equipment installed costs and operating
costs, equipment annual energy consumption, the base case efficiency
projection, and discount rates.
DOE estimates a combined total of 3.647 quads of FFC energy savings
at the max-tech efficiency levels for walk-in doors, panels, and
refrigeration systems may result if amended standards are implemented.
Chapter 10 of the preliminary TSD addresses the NIA.
IV. Public Participation
DOE invites public engagement in this process through participation
in the webinar and submission of written comments and data. After the
webinar and the closing of the comment period, DOE will consider all
timely-submitted comments and additional information obtained from
interested parties, as well as information obtained through further
analyses. Following such consideration, the Department will publish
either a determination that the standards for walk-ins need not be
amended or a NOPR proposing to amend those standards. The NOPR, should
one be issued, would include proposed energy conservation standards for
the products covered by this rulemaking, and members of the public
would be given an opportunity to submit written and oral comments on
the proposed standards.
