I. Background
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 C of EPCA \2\ established the Energy
Conservation Program for Certain Industrial Equipment. (42 U.S.C. 6311-
6317) This includes automatic commercial ice maker (``ACIM'')
equipment, the subject of this rulemaking.
---------------------------------------------------------------------------
\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 reflects 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.
---------------------------------------------------------------------------
On May 11, 2023, DOE published a NOPR (``May 2023 ACIM NOPR'')
proposing to establish new and amended standards for automatic
commercial ice makers. 88 FR 30508. DOE proposed that compliance with
the new and amended standards would be required 3 years after the
publication date of the final rule, should DOE finalize the proposed
standards. 88 FR 30508, 30510. The technical support document (``TSD'')
that presented the methodology and results of the May 2023 ACIM NOPR
analysis is available at www.regulations.gov/document/EERE-2017-BT-STD-0022-0032.
On June 14, 2023, DOE held a public webinar (``June 2023 Public
Webinar'') in which it presented a general overview of the topics
addressed in this rulemaking, allowed time for prepared
[[Page 65629]]
general statements by participants, and encouraged all interested
parties to share their views on issues affecting this rulemaking.
Upon consideration of the views shared in the June 2023 Public
Webinar and public comments DOE received in response to the May 2023
ACIM NOPR, DOE is considering changes to some of the equipment classes
discussed in the May 2023 ACIM NOPR. This NODA presents alternative
equipment classes under consideration as well as updated efficiency
levels, life-cycle costs (``LCC''), payback periods (``PBP''), and
manufacturer impact analysis (``MIA'') results for these equipment
classes. DOE is requesting comments, data, and information regarding
the updated analysis.
DOE notes that it is continuing to consider all of the stakeholder
comments received in response to the May 2023 ACIM NOPR and the June
2023 Public Webinar in further development of the rulemaking.
Furthermore, as noted in the May 2023 ACIM NOPR, based on consideration
of the public comments DOE receives in response to this document and
related information collected and analyzed during the course of this
rulemaking effort, DOE may adopt energy efficiency levels that are
either higher or lower than the proposed standards, or some combination
of level(s) that incorporate the proposed standards in part.
II. Discussion
In the following sections, DOE details its updated analysis for
automatic commercial ice makers.
A. Engineering Analysis
1. Efficiency Analysis
DOE reviewed public comments from the June 2023 Public Webinar and
in response to the May 2023 ACIM NOPR related to harvest rate cutoffs.
In this NODA, DOE updates the analysis for two directly analyzed
equipment classes and two secondary equipment classes and creates four
new secondary equipment classes as a result of the updated analysis in
response to DOE's review of comments related to harvest cutoff rates.
These updated equipment classes are listed in Table II.1 and Table
II.2. DOE also updates the map of secondary classes to the associated
directly analyzed equipment class as presented in Table II.3 based on
the new and updated equipment classes. DOE bases these updates on
public comments DOE received in response to the May 2023 ACIM NOPR and
the June 2023 Public Webinar. Specifically, comments from the Air
Conditioning, Heating, and Refrigeration Institute (``AHRI'') \3\ and
Hoshizaki America, Inc., (``Hoshizaki'') \4\ indicated that a harvest
rate of up to 1,500 pounds per day (``lb/day'') for automatic
commercial ice makers using R-290 is not feasible in all cases for the
500-gram R-290 charge limit and that the baseline levels for automatic
commercial ice makers, which DOE based on design changes made by
manufacturers in response to the December 2022 EPA NOPR, are not
consistent with testing on the equipment. In response to the May 2023
ACIM NOPR, AHRI and Hoshizaki stated that some manufacturer design
plans are speculating at 1,000 lb/day for batch type ice makers and
1,200 lb/day for continuous type ice makers. (AHRI, No. 50 at p. 5;
Hoshizaki, No. 47 at p. 3) \5\ Hoshizaki commented in the June 2023
Public Webinar that Hoshizaki's research and work towards switching
condensers points to 1,000 lb/day for batch type ice makers and 1,200
lb/day for continuous type ice makers rather than the harvest rate of
up to 1,500 pounds per day lb/day in the May 2023 ACIM NOPR.
(Hoshizaki, No. 55 at pp. 20-21) Hoshizaki suggested that the May 2023
ACIM NOPR should be reviewed for this discrepancy and reflect curves
that will meet these criteria and allow for achievable standards.
(Hoshizaki, No. 47 at p. 3)

---------------------------------------------------------------------------
After consideration of these public comments, DOE has updated the
May 2023 ACIM NOPR analysis to reflect the harvest rate cutoff for R-
290 at 1,000 lb/day for batch type ice makers and 1,200 lb/day for
continuous type ice makers.

------------------------------------------------------------------------
DOE requests comment on the equipment class and secondary mapping
updates in this NODA.
a. Baseline Energy Use
For this NODA, DOE updates the baseline for the two directly
analyzed equipment classes shown in Table II.4. For these classes, DOE
considers the current standards as the baseline energy use instead of
an energy use reduction below the DOE energy conservation standard
because DOE has tentatively determined that a harvest rate of up to
1,500 lb/day for automatic commercial ice makers using R-290 is not
feasible in all cases. Consistent with the May 2023 ACIM NOPR, DOE
expects that the baseline level for these equipment classes is equal to
the current DOE ACIM energy conservation standard level, and that
equipment costs and manufacturer investments required to comply with
the refrigerant restrictions proposed in the U.S. Environmental
Protection Agency's NOPR published on December 15, 2022 (see 87 FR
76738) will be in effect prior to the time of compliance for the
proposed amended DOE ACIM standards.

----------------------------------------------------------------------------------------------------------------
DOE requests comment on the baseline energy use updates in this
NODA.
b. Higher Efficiency Levels
For the two directly analyzed classes presented in Table II.1, DOE
maintains the same design options, design option energy use reduction
methodology, and design option cost methodology as the May 2023 ACIM
NOPR. See 87 FR 30508, 30534-30535.

DOE requests comment on the efficiency levels presented in this
NODA.
C. Shipments Analysis
This NODA uses the same volume of shipments as the May 2023 ACIM
NOPR. See 88 FR 30508, 30544-30545. However, with the equipment class
restructuring, shipment volumes for affected equipment classes were
redistributed as applicable to the equipment class changes.
D. 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
automatic commercial ice makers presented in this NODA. For this NODA
analysis, DOE uses the same inputs and assumptions as in the May 2023
ACIM NOPR LCC analysis (see 88 FR 30508, 30539-30540), including using
the Annual Energy Outlook 2022 (``AEO2022'') \6\ for energy price
projections. Details of the analysis inputs and methodology are
available in chapter 8 of the TSD for the May 2023 ACIM NOPR
analysis.\7\ Subsequent rulemaking analyses will be updated with the
most recent data releases (e.g., AEO2023).
---------------------------------------------------------------------------
\6\ Available at www.eia.gov/outlooks/aeo/index.php.
\7\ Available at www.regulations.gov/document/EERE-2017-BT-STD-0022-0036.
---------------------------------------------------------------------------
As stated in the May 2023 ACIM NOPR, DOE's LCC analysis considers
the projected distribution (market shares) of equipment efficiencies
under the no-new-standards case (i.e., the case without amended or new
conservations standards). 88 FR 30508, 30539. As part of the equipment
class restructuring of this NODA, the efficiency distributions also
changed. The estimated market shares of this NODA for the no-new-
standards case for automatic commercial ice makers are shown in Table
II.7.\8\ The efficiency level distribution values were developed by a
review of the DOE Compliance Certification Database (``CCD'').\9\ This
NODA uses the same CCD data set that was used in the May 2023 ACIM
NOPR. Manufacturers are required to submit their data annually on
August 1 to CCD to certify compliance. Although this NODA publishes
after the most recent annual reporting date, using a revised
distribution dataset based on the latest certifications could change
other values not part of this NODA. DOE sorted the portion of equipment
in CCD that corresponds with energy use values from the engineering
analysis.

In the May 2023 ACIM NOPR, DOE published a series of tables (V.3
through V.32) depicting the LCC and PBP for the trial standard levels
(``TSLs'') considered for each equipment class. 88 FR 30508, 30560-
30567. In the second table, impacts are measured relative to the
efficiency distribution in the no-new-standards case in the compliance
year (2027). Because some consumers purchase equipment with higher
efficiency in the no-new-standards case, the average savings are less
than the difference between the average LCC of the baseline equipment
and the average LCC at each TSL. Id.
The results of this NODA analysis are presented in Table II.8
through Table II.11. In the first of each pair of tables, the simple
payback is measured relative to the baseline equipment. In the second
table, impacts are measured relative to the efficiency distribution in
the no-new-standards case in the compliance year (see section II.C of
this document). Because some consumers purchase equipment with higher
efficiency in the no-new-standards case, the average savings are less
than the difference between the average LCC of the baseline equipment
and the average LCC at each efficiency level. The savings refer only to
consumers who are affected by a standard at a given efficiency level.
[[Page 65632]]
Those who already purchase equipment with an efficiency at or above a
given efficiency level are not affected. Consumers for whom the LCC
increases at a given efficiency level experience a net cost.

This NODA only presents changes compared to the May 2023 ACIM NOPR.
No changes occurred in Tables V.19 through V.32 of the May 2023 ACIM
NOPR and, thus, those equipment classes are not presented in this NODA.
---------------------------------------------------------------------------
\14\ Table II.11 corresponds with Table V.9 from the May 2023
ACIM NOPR. This NODA presents new harvest range and the related
values from the harvest range change.
---------------------------------------------------------------------------
E. Manufacturer Impact Analysis
DOE presents the Government Regulatory Impact Model (``GRIM'')
results analyzing the impacts of the updated analysis discussed in this
NODA. The GRIM results summarize the estimated financial impacts of
potential new and amended energy conservation standards on
manufacturers of ACIM equipment, as well as the conversion costs that
DOE estimates manufacturers of ACIM equipment would incur at each TSL.
The methodology and assumptions used in the MIA did not change from the
May 2023 ACIM NOPR except for the analytical changes previously
described in prior sections (i.e., updates stemming from revisions to
the R-290 harvest rate cutoffs,\15\ changes to equipment class harvest
rates to accommodate the new harvest rate cutoffs, and the equipment
class mapping of primary and secondary equipment classes). Table II.12
presents the MIA results. Details of the MIA inputs and methodology are
available in chapter 12 of the TSD for the May 2023 ACIM NOPR.\16\
---------------------------------------------------------------------------
\15\ The R-290 harvest rate cutoff for batch automatic
commercial ice makers was revised to 1,000 lb/day from 1,500 lb/day.
The R-290 harvest rate cutoff for continuous automatic commercial
ice makers was revised to 1,200 lb/day from 1,500 lb/day.

F. National Impact Analysis
This NODA uses the same volume of shipments as the May 2023 ACIM
NOPR. See 88 FR 30508, 30578. However, with the equipment class
restructuring, shipment volumes for affected equipment classes were
redistributed as applicable to the equipment class changes.
---------------------------------------------------------------------------
\17\ To compare these NODA MIA results to the May 2023 ACIM NOPR
MIA results, refer to Table V.40 in the May 2023 ACIM NOPR.

G. Energy Use Equations
Based on the updated analysis presented in this NODA, DOE has
updated the proposed energy use equations in Table II.13 and Table
II.14.
