I. Background 
The Energy Policy and Conservation 
Act, Public Law 94–163, as amended (‘‘EPCA’’),

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. 
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.

5The parenthetical reference provides a reference 
for information located in the docket of DOE’s 
rulemaking to develop energy conservation standards for automatic commercial ice makers. (Docket No. EERE–2017–BT–STD–0022, which is 
maintained at www.regulations.gov). The references are arranged as follows: (commenter name, comment docket ID number, page of that document). 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’’)
3and Hoshizaki America, Inc., 
(‘‘Hoshizaki’’)4indicated 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)
5Hoshizaki 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. B. Efficiency Levels

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’’)
6for 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.
7Subsequent 
rulemaking analyses will be updated with the most recent data releases (e.g., AEO2023). 
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.
8The efficiency level 
distribution values were developed by a review of the DOE Compliance Certification Database (‘‘CCD’’).
9This 
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.

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. 
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,
15changes 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.

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. 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.

Background 
Transport Canada, which is the 
aviation authority for Canada, has 
issued Transport Canada AD CF–2022– 63, dated November 17, 2022 (Transport Canada AD CF–2022–63) (also referred 
to as the MCAI), to correct an unsafe condition on certain De Havilland Aircraft of Canada Limited Model DHC– 8–401 and –402 airplanes. The MCAI states several reports of moisture have been found in the wing-to-fuselage joint, between the mating front spar and rear spar frame segments. This condition, if not corrected, could lead to corrosion and structural degradation of the wing- to-fuselage joint and possible wing separation from the airplane. 
The FAA is proposing this AD to 
address the unsafe condition on these products. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2023–1885. 
Related Service Information Under 1 
CFR Part 51 
The FAA reviewed De Havilland 
Aircraft of Canada Limited Service Bulletin 84–53–81, Revision A, dated August 23, 2022. This service information specifies procedures for a general visual inspection of the fuselage front and rear spar frames (including around the frame bolts) for signs of moisture (i.e., stains and streaks). If 
signs of moisture ingress are noted in the affected structure because of this inspection, then an ultrasonic test and other specified actions will be required, which includes installing a sealant plug, refinishing the frame edge sealing, and removing the existing frame recess sealant between the frame and struts in the cabin. 
This service information is reasonably 
available because the interested parties have access to it through their normal
