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. 

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

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’’) 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

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). 

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-newstandards 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 nonew-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 nonew-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,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

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.

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain De Havilland Aircraft of Canada 

Limited Model DHC–8–401 and –402 

airplanes. This proposed AD was 

prompted by reports of moisture in the 

wing-to-fuselage joint, between the 

mating front spar and rear spar frame 

segments. This proposed AD would 

require a visual inspection of the 

fuselage front and rear spar frames, an 

ultrasonic test if applicable, other 

specified actions, and repair if 

necessary. The FAA is proposing this 

AD to address the unsafe condition on 

these products. 

DATES: The FAA must receive comments 

on this proposed AD by November 9, 

2023.

actually treated as private by its owner. 

Under the Freedom of Information Act 

(FOIA) (5 U.S.C. 552), CBI is exempt 

from public disclosure. If your 

comments responsive to this NPRM 

contain commercial or financial 

information that is customarily treated 

as private, that you actually treat as 

private, and that is relevant or 

responsive to this NPRM, it is important 

that you clearly designate the submitted 

comments as CBI. Please mark each 

page of your submission containing CBI 

as ‘‘PROPIN.’’ The FAA will treat such 

marked submissions as confidential 

under the FOIA, and they will not be 

placed in the public docket of this 

NPRM. Submissions containing CBI 

should be sent to Deep Gaurav, Aviation 

Safety Engineer, FAA, 1600 Stewart 

Avenue, Suite 410, Westbury, NY 

11590; telephone 516–228–7300; email:

rulemaking. 

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 wingto-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
