I. Introduction 

DOE has established a review process 

to conduct a more focused analysis to 

evaluate, based on statutory criteria, 

whether a new or amended energy 

conservation standard is warranted. 

Based on the information received in 

response to the RFI and DOE’s own 

analysis, DOE will determine whether to 

proceed with a rulemaking for a new or 

amended energy conservation standard. 

If DOE makes an initial determination 

that a new or amended energy 

conservation standard would satisfy the 

applicable statutory criteria or DOE’s 

analysis is inconclusive, DOE would 

undertake the preliminary stages of a 

rulemaking to issue a new or amended 

energy conservation standard. If DOE 

makes an initial determination based 

upon available evidence that a new or 

amended energy conservation standard 

would not meet the applicable statutory 

criteria, DOE would engage in a notice 

and comment rulemaking before issuing 

a final determination that new or 

amended energy conservation standards 

are not warranted. 

A. Authority 

The Energy Policy and Conservation 

Act, as amended (‘‘EPCA’’),1 among 

other things, authorizes DOE to regulate 

the energy efficiency of a number of 

consumer products and certain 

industrial equipment. (42 U.S.C. 6291– 


khammond on DSKJM1Z7X2PROD with PROPOSALS
23472 Federal Register / Vol. 87, No. 76 / Wednesday, April 20, 2022 / Proposed Rules 

2For editorial reasons, upon codification in the 

U.S. Code, Part C was redesignated Part A–1. 

6317) Title III, Part C2 of EPCA, added 

by Public Law 95–619, Title IV, section 

441(a) (42 U.S.C. 6311–6317, as 

codified), established the Energy 

Conservation Program for Certain 

Industrial Equipment, which sets forth a 

variety of provisions designed to 

improve energy efficiency. This 

equipment includes small electric 

motors (‘‘SEMs’’), the subject of this 

document. (42 U.S.C. 6311(13)(G); 42 

U.S.C. 6317(b)) 

Under EPCA, DOE’s energy 

conservation program consists 

essentially of four parts: (1) Testing, (2) 

labeling, (3) Federal energy conservation 

standards, and (4) certification and 

enforcement procedures. Relevant 

provisions of EPCA include definitions 

(42 U.S.C. 6311), test procedures (42 

U.S.C. 6314), labeling provisions (42 

U.S.C. 6315), energy conservation 

standards (42 U.S.C. 6313), and the 

authority to require information and 

reports from manufacturers (42 U.S.C. 

6316; 42 U.S.C. 6296). 

EPCA directed DOE to establish a test 

procedure for those SEMs for which 

DOE determined that energy 

conservation standards would (1) be 

technologically feasible and 

economically justified and (2) result in 

significant energy savings. (42 U.S.C. 

6317(b)(1)) Manufacturers of covered 

equipment must use the Federal test 

procedures as the basis for: (1) 

Certifying to DOE that their equipment 

complies with the applicable energy 

conservation standards adopted 

pursuant to EPCA (42 U.S.C. 6316(a); 42 

U.S.C. 6295(s)), and (2) making 

representations about the efficiency of 

that equipment (42 U.S.C. 6314(d)). The 

DOE test procedures for SEMs appear at 

10 CFR part 431, subpart X. 

EPCA further directed DOE to 

prescribe energy conservation standards 

for those SEMs for which test 

procedures were established. (42 U.S.C. 

6317(b)(2)) Additionally, EPCA 

prescribed that any such standards shall 

not apply to any SEM which is a 

component of a covered product under 

42 U.S.C. 6292(a) or covered equipment 

under 42 U.S.C. 6311 of EPCA. (42 

U.S.C. 6317(b)(3)) Federal energy 

efficiency requirements for covered 

equipment established under EPCA 

generally supersede State laws and 

regulations concerning energy 

conservation testing, labeling, and 

standards. (See 42 U.S.C. 6316(a) and 

(b); 42 U.S.C. 6297(a)–(c)). 

EPCA requires that, not later than 6 

years after the issuance of any final rule 

establishing or amending a standard, 

DOE evaluate the energy conservation 

standards for each type of covered 

equipment, including those at issue 

here, and publish either a notice of 

determination that the standards do not 

need to be amended, or a NOPR that 

includes 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)). EPCA 

further provides that, not later than 3 

years after the issuance of a final 

determination not to amend standards, 

DOE must make a new determination 

not to amend the standards or issue a 

NOPR including new proposed energy 

conservation standards. (42 U.S.C. 

6316(a); 42 U.S.C. 6295(m)(3)(B)) DOE 

must make the analysis on which a 

determination is based publicly 

available and provide an opportunity for 

written comment. (42 U.S.C. 6316(a); 42 

U.S.C. 6295(m)(2)) 

In making a determination that the 

standards do not need to be amended, 

DOE must evaluate under the criteria of 

42 U.S.C. 6295(n)(2) whether amended 

standards (1) will result in significant 

conservation of energy, (2) are 

technologically feasible, and (3) are cost 

effective as described under 42 U.S.C. 

6295(o)(2)(B)(i)(II). (42 U.S.C. 6316(a); 

42 U.S.C. 6295(m)(1)(A) and 42 U.S.C. 

6295(n)(2)) Under 42 U.S.C. 

6295(o)(2)(B)(i)(II), an evaluation of cost 

effectiveness requires DOE to consider 

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 products 

which are likely to result from the 

imposition of the standard. 

DOE is publishing this document in 

accordance with its authority under 

EPCA, and in satisfaction of its statutory 

requirement under EPCA. 

B. Rulemaking History 

On January 19, 2021, DOE published 

a notice of final determination (‘‘January 

2021 Final Determination’’) with the 

determination that energy conservation 

standards for SEMs should not be 

amended. 86 FR 4885. In the January 

2021 Final Determination, while DOE 

determined that more stringent 

standards would be technologically 

feasible, DOE also determined that more 

stringent energy conservation standards 

would not be cost effective. 86 FR 4885, 

4906. Therefore, DOE determined that 

the current standards for SEMs did not 

need to be amended. Id. 

C. Deviation From Appendix A 

In accordance with section 3(a) of 10 

CFR part 430, subpart C, appendix A 

(‘‘appendix A’’), applicable to covered 

equipment under 10 CFR 431.4, DOE 

notes that it is deviating from that 

appendix’s provision requiring an early 

assessment review and a 75-day 

comment period for all pre-NOPR 

standards documents. 10 CFR part 430, 

subpart C, appendix A, sections 6(a)(1) 

and 6(d)(2). Given that the market and 

technologies have not changed 

substantively since the prior rulemaking 

during which stakeholders were 

provided an opportunity to comment, 

this RFI with the 30-day comment 

period is expected to provide sufficient 

opportunity for stakeholders to provide 

comment. 

II. Request for Information 

DOE is publishing this RFI to collect 

data and information to inform its 

decision, consistent with its obligations 

under EPCA, as to whether the 

Department should proceed with an 

energy conservation standards 

rulemaking. In the following sections, 

DOE has identified certain topics for 

which information and data are 

requested to assist in the evaluation of 

the potential for amended energy 

conservation standards. DOE also 

welcomes comments on other issues 

relevant to the RFI that may not 

specifically be identified in this 

document. 

A. Significant Savings of Energy 

In the January 2021 Final 

Determination, DOE determined that 

amended standards would not satisfy 

the cost-effectiveness criterion as 

required by EPCA when determining 

whether to amend standards for a given 

covered product or equipment. (42 

U.S.C. 6316(a); 42 U.S.C. 6295(m)(1)(A) 

and 42 U.S.C. 6295(n)(2)(C)) 

Consequently, DOE did not separately 

determine whether the potential energy 

savings would be significant for the 

purposes of 42 U.S.C. 6295(n)(2). 86 FR 

4885, 4899. 

On March 9, 2010, DOE established 

the current energy conservation 

standards for small electric motors. 75 

FR 10874 (‘‘March 2010 Final Rule’’). In 

the March 2010 Final Rule, DOE 

projected that the adopted energy 

conservation standards would result in 

2.2 quadrillion British thermal units 

(‘‘quads’’) of primary energy savings 

over a 30-year period (i.e., 0.29 quad at 

TSL 4b for polyphase SEMs and 1.91 

quad at TSL 7 for single phase SEMs). 

75 FR 10874, 10876. Additionally, DOE 

estimated that an energy conservation 

standard established at an energy 

efficiency level equivalent to that 

achieved using the maximum available 

technology (‘‘max-tech’’) would have

Federal Register / Vol. 87, No. 76 / Wednesday, April 20, 2022 / Proposed Rules 23473 

3 In the January 2021 Final Determination, DOE 

identified three distribution channels for small 

electric motors and estimated their respective 

shares of sales volume: (1) From manufacturers to 

original equipment manufacturers (‘‘OEMs’’), who 

incorporate motors in larger pieces of equipment, to 

OEM equipment distributors, to contractors, and 

then to end-users (65 percent of shipments); (2) 

from manufacturers to wholesale distributors, to 

OEMs, to OEM equipment distributors, to 

contractors, and then to end-users (30 percent of 

shipments); and (3) from manufacturers to 

distributors or retailers, to contractors and then to 

end-users (5 percent of shipments). 86 FR 4885, 

4899. 

4 In the January 2021 Final Determination, DOE 

used two Weibull distributions. One characterizes 

the motor lifetime in total operating hours (i.e., 

mechanical lifetime), while the other characterizes 

the lifetime in years of use in the application (e.g., 

a pump). DOE estimated motor mechanical 

lifetimes of 40,000 hours for polyphase motors and 

30,000 hours for single phase motors. DOE 

estimated average application lifetimes to 7.8–9.7 

years. 86 FR 4885, 4902. 

resulted in 2.7 quads of primary energy 

savings (i.e., an additional 0.5 quads of 

primary energy savings above the 

selected standard) (i.e., 0.37 quad at TSL 

7 for polyphase SEMs and 2.33 quad at 

TSL 8 for single phase SEMs). 75 FR 

10874, 10916. 

While DOE’s request for information 

is not limited to the following issues, 

DOE is particularly interested in 

comment, information, and data on the 

following topics. 

1. DOE seeks comments on whether 

the results of the energy use are still 

relevant. Specifically, DOE seeks inputs 

on whether the inputs to the energy use 

calculation used in the January 2021 

Final Determination are still relevant. If 

revisions are needed, DOE seeks input 

on data sources that DOE can use to 

characterize the variability in annual 

energy consumption for SEMs. 

Specifically, DOE is requesting data and 

information related to: (1) The 

distribution of shipments across 

applications and sectors by equipment 

class or by motor topology and 

horsepower; (2) typical operating hours 

by application and sector; (3) typical 

motor load by application and sector; 

and (4) typical load profiles (i.e., 

percentage of annual operating hours 

spent at specified load points) by 

application and sector. 

2. DOE seeks comments on whether 

the no-new standards case efficiency 

distributions used in the January 2021 

Final Determination still reflect the 

current mix of equipment efficiency in 

the market. DOE seeks data and input 

on the appropriate efficiency 

distribution in the no-new standards 

case for SEMs by equipment class group 

and horsepower range. DOE seeks data 

that would support changes in 

efficiency distributions over time in the 

no-new standards case. 

3. DOE seeks comments on whether or 

not the inputs to the shipments analysis 

used in the March 2010 Final Rule are 

still relevant. DOE further requests 

2011–2021 (or the most recently 

available) annual sales data (i.e., 

number of shipments) for SEMs by 

equipment class. If disaggregated data of 

annual sales are not available at the 

equipment class level, DOE requests 

more aggregated data of annual sales at 

the motor topology level. DOE also 

requests data and information to help 

characterize future shipments of SEMs 

by equipment classes. Specifically, DOE 

requests information on the rate at 

which annual sales (i.e., number of 

shipments) of SEMs is expected to 

change in the next 5–10 years. If 

possible, DOE requests this information 

by motor topology. 

B. Technological Feasibility 

During the January 2021 Final 

Determination, DOE considered a 

number of technology options that 

manufacturers could use to reduce 

energy consumption in SEMs. 

4. DOE seeks comment on any 

changes to these technology options 

since the January 2021 Final 

Determination that could affect whether 

DOE could propose a ‘‘no-newstandards’’ determination, such as an 

insignificant increase in the range of 

efficiencies and performance 

characteristics of these technology 

options. DOE also seeks comment on 

whether there are any updated or new 

technology options that DOE should 

consider in its analysis. 

5. DOE seeks comment on whether 

the methodologies employed in the 

January 2021 Final Determination 

engineering analysis, specifically 

regarding the adoption of the motor 

designs and associated efficiency levels 

considered in the March 2010 Final 

Rule analysis as the basis for the final 

determination, still apply. If not, DOE 

seeks comment on how the 

methodologies should be updated. 

C. Economic Justification 

In determining whether a proposed 

energy conservation standard is 

economically justified, DOE analyzes, 

among other things, the potential 

economic impact on consumers, 

manufacturers, and the Nation. DOE 

seeks comment on whether there are 

economic barriers to the adoption of 

more stringent energy conservation 

standards. DOE also seeks comment and 

data on indicating whether a more 

stringent energy conservation standard 

would be cost effective and 

economically justified. 

While DOE’s request for information 

is not limited to the following issues, 

DOE is particularly interested in 

comment, information, and data on the 

following. 

6. DOE seeks input on whether and 

how the costs estimated for motor 

designs considered in the January 2021 

Final Determination have changed since 

the time of that analysis. DOE also 

requests information on the investments 

(including related costs) necessary to 

incorporate specific design options, 

including, but not limited to, costs 

related to new or modified tooling (if 

any), materials, engineering and 

development efforts to implement each 

design option, and manufacturing/ 

production impacts. 

7. DOE requests information on the 

existence of any distribution channels 

other than the channels that were 

identified in the January 2021 Final 

Determination. DOE also requests data 

on the fraction of sales that go through 

these channels and any other identified 

channels.3

8. DOE seeks comments on whether 

the lifetime inputs used in the January 

2021 Final Determination are still valid. 

DOE seeks data and input on the 

appropriate equipment lifetimes for 

small electric motors both in years and 

in lifetime mechanical hours that DOE 

should apply in its analysis.4

III. Submission of Comments 

DOE invites all interested parties to 

submit in writing by the date under the 

DATES heading, comments and 

information on matters addressed in this 

notification and on other matters 

relevant to DOE’s review of whether 

more-stringent energy conservation 

standards are warranted for SEMs.

RIN 2120–AA64 

Airworthiness Directives; BAE 

Systems (Operations) Limited 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2008–16–06, which applies to all BAE 

Systems (Operations) Limited Model 

4101 airplanes. AD 2008–16–06 requires 

the installation of additional bonding 

leads, inspection of existing bonding 

leads for defects, inspection of fuel 

system pipe runs in the wings to ensure 

appropriate clearances are maintained, 

and corrective actions. Since the FAA 

issued AD 2008–16–06, a safety analysis 

by BAE Systems (Operations) Limited 

identified insufficient bonding for the 

crossfeed valve in the fuel tank area. 

This proposed AD would continue to 

require the actions in AD 2008–16–06, 

and add a requirement to install 

additional bonding leads around the 

crossfeed valve and accomplish a 

resistance check. 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 June 6, 2022. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following
