Notification of a webinar and availability of preliminary technical support document; https://www.regulations.gov/comment/EERE-2020-BT-STD- 0007-0035. the energy efficiency of a number of 
consumer products and certain industrial equipment. (42 U.S.C. 6291– 6317) Title III, Part C
2of EPCA 
established the Energy Conservation Program for Certain Industrial Equipment. (42 U.S.C. 6311–6317). Such equipment includes electric motors, the subject of this rulemaking. 
Pursuant to 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)) EPCA also provides that not later than 6 years after issuance of any final rule establishing or amending a standard, 
DOE must publish either a notice of determination that standards for the 
product do not need to be amended, or a notice of proposed rulemaking 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)) 
Elsewhere in this Federal Register, 
DOE is issuing a direct final rule amending the energy conservation standards for electric motors, along with this proposed rule as required by EPCA. (42 U.S.C. 6295(p)(4)(A)(i)) The amended standard levels in that document were submitted in a joint recommendation (the ‘‘November 2022 Joint Recommendation’’)
3by the 
American Council for an Energy- Efficient Economy (‘‘ACEEE’’), Appliance Standards Awareness Project (‘‘ASAP’’), National Electrical Manufacturers Association (‘‘NEMA’’), Natural Resources Defense Council (‘‘NRDC’’), Northwest Energy Efficiency 
Alliance (‘‘NEEA’’), Pacific Gas & Electric Company (‘‘PG&E’’), San Diego 
Gas & Electric (‘‘SDG&E’’), and Southern California Edison (‘‘SCE’’), hereinafter referred to as ‘‘the Electric Motors Working Group.’’ In a letter comment submitted December 12, 2022, the New York State Energy Research and Development Authority (‘‘NYSERDA’’) expressed its support of the November 2022 Joint Recommendation and urged DOE to implement it in a timely manner. DOE has determined that the November 2022 Joint Recommendation complies with the requirements of EPCA for issuance of a direct final rule. (42 U.S.C. 6295(p)(4)(A)(i)) 
In accordance with these and other 
statutory provisions discussed in this 
document, DOE proposes new and amended energy conservation standards for electric motors. The proposed standards, which are expressed in full- load efficiency, are shown in Table I.1, Table I.2 and Table I.3.

II. Introduction 
The following section briefly 
discusses the statutory authority 
underlying this proposed rule, as well as some of the relevant historical background related to the establishment of standards for electric motors. 
A. Authority 
EPCA authorizes DOE to regulate the 
energy efficiency of a number of 
consumer products and certain industrial equipment. Title III, Part C
4 
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 the energy efficiency of certain types of industrial equipment, including electric motors, the subject of this proposed rule. (42 U.S.C. 6311(1)(A)). The Energy Policy Act of 1992 (‘‘EPACT 1992’’) (Pub. L. 102–486 (Oct. 24, 1992)) further amended EPCA by establishing energy conservation standards and test procedures for certain commercial and industrial electric motors that are manufactured alone or as a component of another piece of equipment. In 
December 2007, Congress enacted the Energy Independence and Security Act of 2007 (‘‘EISA 2007’’) (Pub. L. 110–140 (Dec. 19, 2007)). Section 313(b)(1) of EISA 2007 updated the energy conservation standards for those electric 
motors already covered by EPCA and established energy conservation standards for a larger scope of motors not previously covered by standards. (42 U.S.C. 6313(b)(2)) EISA 2007 also revised certain statutory definitions 
related to electric motors. See EISA 
2007, sec. 313 (amending statutory definitions related to electric motors at 42 U.S.C. 6311(13)). 
The energy conservation program 
under EPCA consists essentially of four parts: (1) testing, (2) labeling, (3) the establishment of 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), 
VerDate Sep<11>2014 16:56 May 31, 2023 Jkt 259001 PO 00000 Frm 00003 Fmt 4702 Sfmt 4702 E:\FR\FM\01JNP1.SGM 01JNP1ddrumheller on DSK120RN23PROD with PROPOSALS135768 Federal Register / Vol. 88, No. 105 / Thursday, June 1, 2023 / Proposed Rules 
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). 
Federal energy efficiency 
requirements for covered equipment established under EPCA generally supersede State laws and regulations concerning energy conservation testing, labeling, and standards. (42 U.S.C. 6316(a) and (b); 42 U.S.C. 6297) DOE may, however, grant waivers of Federal preemption in limited instances for particular State laws or regulations, in accordance with the procedures and other provisions set forth under EPCA. (See 42 U.S.C. 6316(a) (applying the 
preemption waiver provisions of 42 U.S.C. 6297)) 
Subject to certain criteria and 
conditions, DOE is required to develop test procedures to measure the energy efficiency, energy use, or estimated annual operating cost of each covered product. (42 U.S.C. 6314(a), 42 U.S.C. 6295(o)(3)(A) and 42 U.S.C. 6295(r)) 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)). Similarly, DOE must use these test procedures to determine whether the equipment complies with relevant standards promulgated under EPCA. (42 U.S.C. 6316(a); 42 U.S.C. 6295(s)) The DOE test procedures for electric motors appear at title 10 of the Code of Federal Regulations (‘‘CFR’’) part 431, subpart B, appendix B. 
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 notice of determination that standards for the product do not need to be 
amended, or a notice of proposed rulemaking 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)) 
DOE must follow specific statutory 
criteria for prescribing new or amended standards for covered equipment, including electric motors. Any new or amended standard for a covered product must be designed to achieve the maximum improvement in energy efficiency that the Secretary of Energy determines is technologically feasible and economically justified. (42 U.S.C. 6316(a); 42 U.S.C. 6295(o)(2)(A) and 42 U.S.C. 6295(o)(3)(B)) 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)) 
Moreover, DOE may not prescribe a 
standard: (1) for certain products, including electric motors, if no test procedure has been established for the product, or (2) if DOE determines by rule that the standard is not technologically feasible or economically justified. (42 U.S.C. 6316(a); 42 U.S.C. 6295(o)(3)(A)–(B)) In deciding whether a proposed standard is economically justified, DOE must determine whether the benefits of the standard exceed its burdens. (42 U.S.C. 6316(a); 42 U.S.C. 6295(o)(2)(B)(i)) DOE must make this determination after receiving comments on the proposed standard, and by considering, to the greatest extent practicable, the following seven statutory factors: 
(1) The economic impact of the standard 
on 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 covered 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)) 
Further, EPCA, as codified, 
establishes a rebuttable presumption 
that a standard is economically justified if the Secretary finds that the additional cost to the consumer of purchasing a product 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, as codified, 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 product. (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 product 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 a covered product that has two or more subcategories. DOE must specify a different standard level for a type or class of products 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 products within such type (or class); or (B) have a capacity or other performance-related feature which other products 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 such a 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)) 
Finally, EISA 2007 amended EPCA, in 
relevant part, to grant DOE authority to issue a final rule (i.e., a ‘‘direct final 
rule’’) establishing an energy conservation standard on receipt of a statement submitted jointly by interested persons that are fairly representative of relevant points of view (including representatives of manufacturers of covered products, States, and efficiency advocates), as determined by the Secretary, that contains recommendations with respect to an energy or water conservation standard that are in accordance with the provisions of 42 U.S.C. 6295(o). (42 U.S.C. 6295(p)(4)) Pursuant to 42 U.S.C. 
6295(p)(4), the Secretary must also determine whether a jointly-submitted recommendation for an energy or water conservation standard satisfies 42 U.S.C. 6295(o) or 42 U.S.C. 6313(a)(6)(B), as applicable. 
The direct final rule must be 
published simultaneously with a NOPR that proposes an energy or water conservation standard that is identical

5The members of the Electric Motors Working 
Group included ACEEE, ASAP, NEMA, NRDC, 
NEEA, PG&E, SDG&E, and SCE. to the standard established in the direct 
final rule, and DOE must provide a public comment period of at least 110 days on this proposal. (42 U.S.C. 6295(p)(4)(A)–(B)) Based on the comments received during this period, the direct final rule will either become effective, or DOE will withdraw it not later than 120 days after its issuance if (1) one or more adverse comments is received, and (2) DOE determines that those comments, when viewed in light of the rulemaking record related to the direct final rule, provide a reasonable basis for withdrawal of the direct final rule under 42 U.S.C. 6295(o), 42 U.S.C. 6313(a)(6)(B), or any other applicable law. (42 U.S.C. 6295(p)(4)(C)) Receipt of an alternative joint recommendation may also trigger a DOE withdrawal of the direct final rule in the same manner. Id. After withdrawing a direct final rule, 
DOE must proceed with the notice of proposed rulemaking published simultaneously with the direct final rule and publish in the Federal Register the reasons why the direct final rule was withdrawn. Id. 
Typical of other rulemakings, it is the 
substance, rather than the quantity, of comments that will ultimately determine whether a direct final rule will be withdrawn. To this end, the substance of any adverse comment(s) received will be weighed against the anticipated benefits of the jointly- submitted recommendations and the likelihood that further consideration of the comment(s) would change the results of the rulemaking. DOE notes that, to the extent an adverse comment had been previously raised and addressed in the rulemaking proceeding, such a submission will not typically provide a basis for withdrawal of a direct final rule. 
B. Background 
In the May 2020 Early Assessment 
Review RFI, DOE stated that it was 
initiating 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 electric motors and sought information related to that effort. Specifically, DOE sought data and information that could enable the agency to 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 the foregoing. 85 FR 30878, 30879. On March 2, 2022, DOE published the 
preliminary analysis for electric motors. 87 FR 11650 (‘‘March 2022 Preliminary Analysis’’). In conjunction with the March 2022 Preliminary Analysis, DOE published a technical support document (‘‘March 2022 Prelim TSD’’) which presented the results of the in-depth technical analyses in the following areas: (1) Engineering; (2) markups to determine equipment price; (3) energy use; (4) life cycle cost (‘‘LCC’’) and payback period (‘‘PBP’’); and (5) national impacts. The results presented included the current scope of electric motors regulated at 10 CFR 431.25, in addition to an expanded scope of motors, including electric motors above 500 horsepower, air-over electric motors, and small, non-small-electric- motor, electric motors (‘‘SNEM’’). See Chapter 2 of the March 2022 Prelim TSD. 
By letter dated on November 15, 2022, 
DOE received a joint recommendation for energy conservation standards for electric motors (‘‘November 2022 Joint Recommendation’’). The November 2022 Joint Recommendation represented the motors industry, energy efficiency organizations and utilities (collectively, ‘‘the Electric Motors Working Group’’).
5 
The November 2022 Joint Recommendation addressed energy conservation standards for medium electric motors that are 1–750 hp and polyphase, and air-over medium electric motors. On December 9, 2022, DOE received a supplemental letter to the November 2022 Joint Recommendation from the Electric Motors Working Group. The supplemental letter provided additional guidance on the recommended levels for open medium electric motors rated 100 hp to 250 hp, and a recommended compliance date for standards presented in the November 2022 Joint Recommendation. A summary of the specific recommendations contained in the November 2022 Joint Recommendation may be found in the direct final rule published elsewhere in this Federal Register. 
After carefully considering the 
November 2022 Joint Recommendation and supplement for amending the energy conservation standards for electric motors submitted by the Electric Motors Working Group, DOE has determined that these recommendations are in accordance with the statutory requirements of 42 U.S.C. 6295(p)(4) for the issuance of a direct final rule. More specifically, these 
recommendations comprise a statement 
submitted by interested persons who are fairly representative of relevant points of view on this matter. In appendix A to subpart C of 10 CFR part 430 (‘‘appendix A’’), DOE explained that to be ‘‘fairly representative of relevant points of view,’’ the group submitting a joint statement must, where appropriate, include larger concerns and small business in the regulated industry/ manufacturer community, energy advocates, energy utilities, consumers, and States. However, it will be necessary to evaluate the meaning of ‘‘fairly representative’’ on a case-by-case basis, subject to the circumstances of a particular rulemaking, to determine whether fewer or additional parties must be part of a joint statement in order to be ‘‘fairly representative of relevant points of view.’’ Section 10 of appendix A. In reaching this determination, DOE took into consideration the fact that the Joint Recommendation was signed and submitted by a broad cross-section of interests, including a manufacturers’ trade association, environmental and energy-efficiency advocacy organizations, and electric utility companies. NYSERDA, a state organization, also submitted a letter supporting the Joint Recommendation. DOE notes that these organizations include the relevant points of view specifically identified by Congress: manufacturers of covered products, States, and efficiency advocates. (42 U.S.C. 6295(p)(4)(A)) 
DOE has evaluated the November 
2022 Joint Recommendation and believes that it meets the EPCA requirements for issuance of a direct final rule. As a result, DOE published a direct final rule establishing energy conservation standards for electric motors elsewhere in this Federal Register. If DOE receives adverse comments that may provide a reasonable basis for withdrawal and withdraws the direct final rule, DOE will consider those comments and any other comments received in determining how to proceed with this proposed rule. 
For further background information 
on these proposed standards and the supporting analyses, please see the direct final rule published elsewhere in this Federal Register. That document, 
and the accompanying technical support document (‘‘TSD’’), include additional discussion of the EPCA requirements for promulgation of energy conservation standards; the history of the standards rulemaking for electric 
motors; and information on the test procedures used to measure the energy

efficiency of electric motors. Those 
documents also contain an in-depth discussion of the analyses conducted in support of this proposed rulemaking, the methodologies DOE used in conducting those analyses, and the analytical results. III. Proposed Standards 
A. Benefits and Burdens of TSLs 
Considered for Electric Motor Standards 
Table III.1 and Table III.2 summarize 
the quantitative impacts estimated for each TSL for electric motors. The national impacts are measured over the lifetime of electric motors purchased in 
the 30-year period that begins in the anticipated year of compliance with amended standards (2027–2056). The energy savings, emissions reductions, and value of emissions reductions refer to full-fuel-cycle results.

Note: This table presents the costs and benefits associated with electric motors shipped in 2027–2056. These results include benefits to con-
sumers which accrue after 2056 from the products shipped in 2027–2056. 
* Climate benefits are calculated using four different estimates of the SC–CO 2, SC–CH 4and SC–N 2O. Together, these represent the global 
SC–GHG. For presentational purposes of this table, the climate benefits associated with the average SC–GHG at a 3 percent discount rate are 
shown, but the Department does not have a single central SC–GHG point estimate. 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 ef-
fect, pending resolution of the Federal government’s appeal of that injunction or a further court order. Among other things, the preliminary injunc-tion 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, 2 021—to 
monetize the benefits of reducing greenhouse gas emissions. In the absence of further intervening court orders, DOE has reverted to its ap-proach prior to the injunction and presents monetized benefits where appropriate and permissible under law. 
** Health benefits are calculated using benefit-per-ton values for NO
Xand SO 2. DOE is currently only monetizing (for NO Xand SO 2) PM 2.5pre-
cursor health benefits and (for NO X) ozone precursor health benefits, but will continue to assess the ability to monetize other effects such as 
health benefits from reductions in direct PM 2.5emissions. The health benefits are presented at real discount rates of 3 and 7 percent. See sec-
tion IV.L of this document for more details. 
† Total and net benefits include consumer, climate, and health benefits. For presentation purposes, total and net benefits for both the 3-percent 
and 7-percent cases are presented using the average SC–GHG with 3-percent discount rate, but the Department does not have a single central SC–GHG point estimate. DOE emphasizes the importance and value of considering the benefits calculated using all four SC–GHG est imates. 
‡Costs include incremental equipment costs as well as installation costs.

The entry ‘‘N/A’’ means not applicable because there is no change in the standard at certain TSLs. 
* No impact because there are no shipments below the efficiency level corresponding to TSL1 and TSL2 for RU9. ** Weighted by shares of each equipment class in total projected shipments in 2027 for impacted consumers. 
DOE first considered TSL 4, which 
represents the max-tech efficiency 
levels. At this level, DOE expects that all equipment classes would require 35H210 silicon steel and die-cast copper rotors. DOE estimates that approximately 0.34 percent of annual shipments across all electric motor equipment classes currently meet the max-tech efficiencies required. TSL 4 would save an estimated 23.6 quads of energy, an amount DOE considers significant. Under TSL 4, the NPV of consumer benefit would be ¥$17.67 billion using a discount rate of 7 percent, and ¥$11.30 billion using a discount rate of 3 percent. 
The cumulative emissions reductions 
at TSL 4 are 725.80 Mt of CO
2, 278.95 thousand tons of SO 2, 1,173.58 
thousand tons of NO X, 1.82 tons of Hg, 
5,415.99 thousand tons of CH 4, and 6.59 
thousand tons of N 2O. The estimated 
monetary value of the climate benefits from reduced GHG emissions (associated with the average SC–GHG at a 3-percent discount rate) at TSL 4 is $30.07 billion. The estimated monetary value of the health benefits from reduced SO
2and NO Xemissions at TSL 
4 is $18.13 billion using a 7-percent discount rate and $51.90 billion using a 3-percent discount rate. 
Using a 7-percent discount rate for 
consumer benefits and costs, health benefits from reduced SO
2and NO X 
emissions, and the 3-percent discount rate case for climate benefits from reduced GHG emissions, the estimated total NPV at TSL 4 is $30.54 billion. Using a 3-percent discount rate for all benefits and costs, the estimated total NPV at TSL 4 is $70.67 billion. 
At TSL 4, for the largest equipment 
class group and horsepower ranges, which are represented by RU1 and RU2, which together represent approximately 90 percent of annual shipments, there is a life cycle cost savings of ¥$276.4 and ¥$309.4 and a payback period of 20.3 years and 11.9 years, respectively. For these equipment classes, the fraction of customers experiencing a net LCC cost is 95.9 percent and 75.0 percent due to increases in total installed cost of $434.7 and $1,003.0, respectively. Overall, for the remaining equipment class groups 
VerDate Sep<11>2014 16:56 May 31, 2023 Jkt 259001 PO 00000 Frm 00007 Fmt 4702 Sfmt 4702 E:\FR\FM\01JNP1.SGM 01JNP1ddrumheller on DSK120RN23PROD with PROPOSALS135772 Federal Register / Vol. 88, No. 105 / Thursday, June 1, 2023 / Proposed Rules 
6For RU1 and RU2, EL1 = EL2. See section 
IV.C.1.c. of the associated direct final rule 
published elsewhere in this Federal Register. 7In terms of standardized horsepowers, this 
would correspond to 100–250 hp when applying the from 10 CFR 431.25(k) (and new 10 CFR 431.25(q)). and horsepower ranges, a majority of 
electric motor consumers (84.5 percent) would experience a net cost and the average LCC savings would be negative for all remaining equipment class groups and horsepower ranges. 
At TSL 4, the projected change in 
INPV ranges from a decrease of $11,090 million to a decrease of $8,863 million, which corresponds to decreases of 220.8 percent and 176.4 percent, respectively. DOE estimates that industry must invest $13,516 million to comply with standards set at TSL 4. The significant increase in product and capital conversion costs is because DOE assumes that electric motor manufacturers will need to use die-cast copper rotors for most, if not all, electric motors manufactured to meet this TSL. This technology requires a significant level of investment because almost all existing electric motor production machinery would need to be replaced or significantly modified. Based on the shipments analysis used in the NIA, DOE estimates that approximately 0.3 percent of all electric motor shipments will meet the efficiency levels required at TSL 4, in the no-new-standards case in 2027, the compliance year of new and amended standards. 
The Secretary concludes that at TSL 
4 for electric motors, the benefits of energy savings, emission reductions, and the estimated monetary value of the emissions reductions are outweighed by the negative NPV of consumer benefits, economic burden on many consumers, and the impacts on manufacturers, including the extremely large conversion costs, profit margin impacts that will result in a negative INPV, and the lack of manufacturers currently offering products meeting the efficiency levels required at this TSL. A majority of electric motor consumers (86.3 percent) would experience a net cost and the average LCC savings for each representative unit DOE examined is negative. In both manufacturer markup scenarios, INPV is negative at TSL 4, which implies that manufacturers would never recover the conversion costs they must make to produce electric motors at TSL 4. Consequently, the Secretary concludes that TSL 4 is not economically justified. 
DOE then considered TSL 3, which 
represents a level corresponding to the 
IE4 level, except for AO-polyphase specialized frame size electric motors, where it corresponds to a lower level of efficiency (i.e., NEMA Premium level). 
TSL 3 would save an estimated 10.4 quads of energy, an amount DOE considers significant. Under TSL 3, the NPV of consumer benefit would be ¥$7.60 billion using a discount rate of 7 percent, and ¥$4.85 billion using a discount rate of 3 percent. 
The cumulative emissions reductions 
at TSL 3 are 319.24 Mt of CO
2, 122.75 
thousand tons of SO 2, 516.00 thousand 
tons of NO X, 0.80 tons of Hg, 2,379.75 
thousand tons of CH 4, and 2.90 
thousand tons of N 2O. The estimated 
monetary value of the climate benefits from reduced GHG emissions (associated with the average SC–GHG at a 3-percent discount rate) at TSL 3 is $13.49 billion. The estimated monetary value of the health benefits from reduced SO
2and NO Xemissions at TSL 
3 is 8.19 billion using a 7-percent discount rate and $23.16 billion using a 3-percent discount rate. 
Using a 7-percent discount rate for 
consumer benefits and costs, health benefits from reduced SO
2and NO X 
emissions, and the 3-percent discount rate case for climate benefits from reduced GHG emissions, the estimated total NPV at TSL 3 is $14.08 billion. Using a 3-percent discount rate for all benefits and costs, the estimated total NPV at TSL 3 is $31.80 billion. 
At TSL 3, for the largest equipment 
class group and horsepower ranges, which are represented by RU1 and RU2, there is a life cycle cost savings of ¥$101.8 and ¥$336.9 and a payback period of 16.7 and 15.4, respectively.

For these equipment classes, the fraction of customers experiencing a net LCC cost is 64.1 percent and 82.2 percent due to increases in total installed cost of $171.3 and $690.5, respectively. Overall, for the remaining equipment class groups and horsepower ranges, a majority of electric motor consumers (55.5 percent) would experience a net cost and the shipments-weighted average LCC savings would be negative for all remaining equipment class groups and horsepower ranges. 
At TSL 3, the projected change in 
INPV ranges from a decrease of $1,364 million to a decrease of $342 million, which correspond to decreases of 27.2 percent and 6.8 percent, respectively. DOE estimates that industry must invest $1,618 million to comply with standards set at TSL 3. Based on the shipments analysis used in the NIA, DOE estimates that approximately 13.3 percent of all electric motor shipments will meet or exceed the efficiency levels required at TSL 3, in the no-new- standards case in 2027, the compliance year of new and amended standards. 
The Secretary concludes that at TSL 
3 for electric motors, the benefits of energy savings, emission reductions, and the estimated monetary value of the emissions reductions are outweighed by the negative NPV of consumer benefits, economic burden on many consumers, and the impacts on manufacturers, including the large conversion costs, profit margin impacts that could result in a large reduction in INPV, and the lack of manufacturers currently offering products meeting the efficiency levels required at this TSL. A majority of electric motor consumers (70.6 percent) would experience a net cost and the average LCC savings would be negative. The potential reduction in INPV could be as high as 27.2 percent. Consequently, the Secretary concludes that TSL 3 is not economically justified. 
DOE then considered TSL 2, the 
standard levels recommended in the November 2022 Joint Recommendation by the Electric Motors Working Group. TSL 2 would also align with the EU Ecodesign Directive 2019/1781, which requires IE4 levels for 75–200 kW motors.
7TSL 2 would save an estimated 
3.0 quads of energy, an amount DOE considers significant. Under TSL 2, the NPV of consumer benefit would be $2.23 billion using a discount rate of 7 percent, and $7.47 billion using a discount rate of 3 percent. 
The cumulative emissions reductions 
at TSL 2 are 91.69 Mt of CO
2, 35.12 
thousand tons of SO 2, 148.74 thousand 
tons of NO X, 0.23 tons of Hg, 690.10 
thousand tons of CH 4, and 0.82 
thousand tons of N 2O. The estimated 
monetary value of the climate benefits from reduced GHG emissions (associated with the average SC–GHG at a 3-percent discount rate) at TSL 2 is $3.14 billion. The estimated monetary value of the health benefits from reduced SO
2and NO Xemissions at TSL 
2 is $1.76 billion using a 7-percent discount rate and $5.72 billion using a 3-percent discount rate. 
Using a 7-percent discount rate for 
consumer benefits and costs, health benefits from reduced SO
2and NO X 
emissions, and the 3-percent discount rate case for climate benefits from reduced GHG emissions, the estimated total NPV at TSL 2 is $7.13 billion. Using a 3-percent discount rate for all benefits and costs, the estimated total NPV at TSL 2 is $16.33 billion. 
At TSL 2, for the largest equipment 
class group and horsepower ranges, which are represented by RU1 and RU2, there would be no changes in the standards. Overall, for the remaining

equipment class groups and horsepower 
ranges, 14.9 percent of electric motor consumers would experience a net cost and the shipments-weighted average LCC savings would be positive for all remaining equipment class groups and horsepower ranges. 
At TSL 2, the projected change in 
INPV ranges from a decrease of $333 million to a decrease of $303 million, which correspond to decreases of 6.6 percent and 6.0 percent, respectively. DOE estimates that industry must invest $468 million to comply with standards set at TSL 2. Based on the shipments analysis used in the NIA, DOE estimates that approximately 96.2 percent of all electric motor shipments will meet or exceed the efficiency levels required at TSL 2, in the no-new-standards case in 2027, the compliance year of new and amended standards. 
After considering the analysis and 
weighing the benefits and burdens, the Secretary concludes that a standard set at TSL 2 for electric motors would be economically justified. At this TSL, the average LCC savings is positive. Only an estimated 14.9 percent of electric motor consumers experience a net cost. The FFC national energy savings are significant and the NPV of consumer benefits is positive using both a 3- percent and 7-percent discount rate. Notably, the benefits to consumers vastly outweigh the cost to manufacturers. Notably, at TSL 2, the NPV of consumer benefits, even measured at the more conservative discount rate of 7 percent is over 6 times higher than the maximum estimated manufacturers’ loss in INPV. The standard levels at TSL 2 are economically justified even without weighing the estimated monetary value of emissions reductions. When those emissions reductions are included— representing $3.14 billion in climate benefits (associated with the average SC–GHG at a 3-percent discount rate), and $5.72 billion (using a 3-percent discount rate) or $1.76 billion (using a 
7-percent discount rate) in health benefits—the rationale becomes stronger still. 
As stated, DOE conducts the walk- 
down analysis to determine the TSL that represents the maximum improvement in energy efficiency that is technologically feasible and economically justified as required under EPCA. The walk-down is not a comparative analysis, as a comparative analysis would result in the maximization of net benefits instead of energy savings that are technologically feasible and economically justified, which would be contrary to the statute. 86 FR 70892, 70908. Although DOE has not conducted a comparative analysis to select the energy conservation standards, DOE notes that as compared to TSL 3 and TSL 4, TSL 2 has higher average LCC savings for consumers, significantly smaller percentages of electric motor consumers experiencing a net cost, a lower maximum decrease in INPV, and lower manufacturer conversion costs. 
Although DOE considered amended 
standard levels for electric motors by grouping the efficiency levels for each equipment class groups and horsepower ranges into TSLs, DOE evaluates all analyzed efficiency levels in its analysis. For all equipment class groups and horsepower ranges, TSL 2 represents the maximum energy savings that does not result in the majority of consumers experiencing a net LCC cost. The ELs at the proposed TSL result in average positive LCC savings for all equipment class groups and horsepower ranges, significantly reduce the number of consumers experiencing a net cost, and reduce the decrease in INPV and conversion costs to the point where DOE has concluded they are economically justified, as discussed for TSL 2 in the preceding paragraphs. 
Therefore, based on the previous 
considerations, DOE proposes to adopt 
the energy conservation standards for electric motors at TSL 2. The proposed amended energy conservation standards for electric motors, which are expressed as full-load efficiency, are shown in Table I.1, Table I.2, and Table I.3. 
B. Annualized Benefits and Costs of the 
Proposed Standards 
The benefits and costs of the proposed 
standards can also be expressed in terms of annualized values. The annualized net benefit is (1) the annualized national economic value (expressed in 2021$) of the benefits from operating products that meet the proposed standards (consisting primarily of operating cost savings from using less energy, minus increases in product purchase costs, and (2) the annualized monetary value of the climate and health benefits from emission reductions. 
Table III.3 shows the annualized 
values for electric motors under TSL 2, expressed in 2021$. The results under the primary estimate are as follows. 
Using a 7-percent discount rate for 
consumer benefits and costs and NO
X 
and SO 2reduction benefits, and a 3- 
percent discount rate case for GHG social costs, the estimated cost of the standards for electric motors is $62.1 million per year in increased equipment costs, while the estimated annual benefits are $254.8 million from reduced equipment operating costs, $164.8 million from GHG reductions, and $151.4 million from reduced NO
X 
and SO 2emissions. In this case, the net 
benefit amounts to $508.9 million per year. 
Using a 3-percent discount rate for all 
benefits and costs, the estimated cost of the standards for electric motors is $71.0 million per year in increased equipment costs, while the estimated annual benefits are $463.6 million in reduced operating costs, $164.8 million from GHG reductions, and $300.7 million from reduced NO
Xand SO 2emissions. 
In this case, the net benefit amounts to $858.2 million per year.

Note: This table presents the costs and benefits associated with electric motors shipped in 2027–2056. These results include benefits to con-
sumers which accrue after 2056 from the products shipped in 2027–2056. The Primary, Low Net Benefits, and High Net Benefits Estimates uti-
lize projections of energy prices from the AEO2022 Reference case, Low Economic Growth case, and High Economic Growth case, respectively. 
In addition, incremental equipment costs reflect a constant rate in the Primary Estimate, an increasing rate in the Low Net Benefits Estimate, and a declining rate in the High Net Benefits Estimate. The methods used to derive projected price trends are explained in section IV.H.3 of this doc-ument. Note that the Benefits and Costs may not sum to the Net Benefits due to rounding. 
* Climate benefits are calculated using four different estimates of the global SC–GHG (see section IV.L of this document). For p resentational 
purposes of this table, the climate benefits associated with the average SC–GHG at a 3 percent discount rate are shown, but the Department does not have a single central SC–GHG point estimate, and it emphasizes the importance and value of considering the benefits calculated using all four SC–GHG estimates. 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 ap-peal 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 Inter-agency 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 has reverted to its approach prior to the injunction and presents monetized benefits where appropriate and permissible under law. 
** Health benefits are calculated using benefit-per-ton values for NO
Xand SO 2. DOE is currently only monetizing (for SO 2and NO X) PM 2.5pre-
cursor health benefits and (for NO X) ozone precursor health benefits, but will continue to assess the ability to monetize other effects such as 
health benefits from reductions in direct PM 2.5emissions. The health benefits are presented at real discount rates of 3 and 7 percent. See sec-
tion IV.L of this document for more details. 
† Total benefits for both the 3-percent and 7-percent cases are presented using the average SC–GHG with 3-percent discount rate, but the 
Department does not have a single central SC–GHG point estimate. 
‡Costs include incremental equipment costs as well as installation costs. 
IV. Procedural Issues and Regulatory 
Review 
The regulatory reviews conducted for 
this proposed rule, except for the Regulatory Flexibility Act discussed in section IV.A, are identical to those conducted for the direct final rule published elsewhere in this Federal Register. Please see the direct final rule for further details. 
A. Review Under the Regulatory 
Flexibility Act 
The Regulatory Flexibility Act (5 
U.S.C. 601 et seq.) requires preparation 
of an initial regulatory flexibility analysis (‘‘IRFA’’) and a final regulatory flexibility analysis (‘‘FRFA’’) for any rule that by law must be proposed for public comment, unless the agency certifies that the rule, if promulgated, will not have a significant economic impact on a substantial number of small entities. As required by E.O. 13272, ‘‘Proper Consideration of Small Entities in Agency Rulemaking,’’ 67 FR 53461 (Aug. 16, 2002), DOE published procedures and policies on February 19, 2003, to ensure that the potential impacts of its rules on small entities are properly considered during the rulemaking process. 68 FR 7990. DOE has made its procedures and policies available on the Office of the General Counsel’s website (www.energy.gov/gc/ office-general-counsel). DOE has prepared the following IRFA for the products that are the subject of this proposed rulemaking. 
For manufacturers of electric motors, 
the SBA has set a size threshold, which defines those entities classified as ‘‘small businesses’’ for the purposes of the statute. DOE used the SBA’s small business size standards to determine whether any small entities would be subject to the requirements of the rule. (See 13 CFR part 121.) The size 
standards are listed by North American Industry Classification System (‘‘NAICS’’) code and industry description and are available at www.sba.gov/document/support-table- size-standards. Manufacturing of 
electric motors is classified under NAICS 335312, ‘‘Motor and Generator Manufacturing.’’ The SBA sets a threshold of 1,250 employees or fewer for an entity to be considered as a small 
business for this category. 
1. Description of Reasons Why Action Is 
Being Considered 
EPCA requires that, not later than 6 
years after the issuance of any final rule establishing or amending a standard, DOE must publish either a notice of determination that standards for the product 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(e)(1); 42 U.S.C. 6295(m)(1)) Additionally, under the authority provided by 42 U.S.C. 6295(p)(4), DOE is issuing a direct final rule establishing energy conservation standards for 
electric motors These standard levels were submitted jointly to DOE on November 15, 2022, by groups representing manufacturers, energy and environmental advocates, and consumer groups (the Electric Motors Working Group).

In a letter comment submitted December 12, 2022, the New York State Energy Research and Development Authority (‘‘NYSERDA’’) expressed its support of the November 2022 Joint Recommendation and urged DOE to implement it in a timely manner. 
9For editorial reasons, upon codification in the 
U.S. Code, Part C was redesignaated Part A–1. comments, the November 2022 Joint 
Recommendation, recommends specific energy conservation standards for electric motors that DOE has determined satisfy the EPCA requirements in 42 U.S.C. 6295(o). 
2. Objectives of, and Legal Basis for, 
Rule 
EPCA authorizes DOE to regulate the 
energy efficiency of a number of consumer products and certain industrial equipment. Title III, Part C
9 
of EPCA added by Pub. L. 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 the energy efficiency of certain types of industrial equipment, including electric motors, the subject of this proposed rule. (42 U.S.C. 6311(1)(A)). DOE has previously established energy conservation standards for electric motors at 10 CFR 431.25. 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 notice of determination that standards for the product do not need to be amended, or a notice of proposed rulemaking 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)) DOE must follow specific statutory criteria for prescribing new or amended standards for covered equipment, including electric motors. Any new or amended standard for a covered equipment must be designed to achieve the maximum improvement in energy efficiency that the Secretary of Energy determines is technologically feasible and economically justified. (42 U.S.C. 6316(a); 42 U.S.C. 6295(o)(2)(A) and 42 U.S.C. 6295(o)(3)(B)). As noted previously, DOE has the authority to issue a final rule (i.e., a ‘‘direct final 
rule’’) establishing an energy conservation standard on receipt of a statement submitted jointly by interested persons that are fairly representative of relevant points of view (including representatives of manufacturers of covered products, 
States, and efficiency advocates), as determined by the Secretary, that contains recommendations with respect to an energy or water conservation standard that are in accordance with the provisions of 42 U.S.C. 6295(o). (42 U.S.C. 6295(p)(4)) 
3. Description on Estimated Number of 
Small Entities Regulated 
To estimate the number of companies 
that could be small business manufacturers of electric motors covered by this proposed rulemaking, DOE conducted a market survey using publicly available information. DOE’s research involved DOE’s publicly available Compliance Certification Database (‘‘CCD’’), industry trade association membership directories (including NEMA), and information from previous rulemakings. DOE also asked stakeholders and industry representatives if they were aware of any other small manufacturers during manufacturer interviews and DOE working groups. DOE used information from these sources to create a list of companies that potentially manufacture electric motors covered by this proposed rulemaking. As necessary, DOE contacted companies to determine whether they met the SBA’s definition of a small business manufacturer. DOE screened out companies that do not 
offer equipment covered by this rulemaking, do not meet the definition of a ‘‘small business,’’ or are foreign owned and operated. 
DOE initially identified 
approximately 74 unique potential manufacturers of electric motors sold in the U.S that are covered by this proposed rulemaking. DOE screened out companies that had more than 1,250 employees or companies that were completely foreign owned and operated. Of the 74 manufacturers that potentially manufacture electric motors covered by this proposed rulemaking, DOE identified 11 companies that meet SBA’s definition of a small business. 
4. Description and Estimate of 
Compliance Requirements Including Differences in Cost, if Any, for Different Groups of Small Entities 
Six major manufacturers supply 
approximately 90 percent of the market for electric motors covered by this proposed rulemaking. None of the major electric motor manufacturers covered by this proposed rulemaking are a small business. DOE is adopting new energy conservation standards for some AO electric motors and NEMA Design A and B electric motors between 500 hp and 75 hp. Additionally, DOE is amending energy conservation standards for 
NEMA Design A and B electric motors between 100 hp and 250 hp. Based on a review on the 11 small businesses’ equipment offerings online, DOE was not able to identify any small business electric motor manufacturer that manufactures AO electric motors covered by this proposed rulemaking. Therefore, the remainder of the discussion in this section focuses on NEMA Design A and B electric motors between 100 hp and 250 hp and NEMA Design A and B electric motors between 500 hp and 750 hp that are covered by this proposed rulemaking. 
Most of the identified small 
businesses primarily focus on selling application specific motors to OEMs (which are then embedded in the OEM’s machinery). DOE estimates that approximately 97 percent of NEMA Design A and B electric motor sales covered by this proposed rulemaking are between 1–100 hp or 250–500 hp. DOE is not proposing to amend energy conservation standards for NEMA Design A and B electric motors between these horsepower ranges. Therefore, the majority of the NEMA Design A and B electric motors that are manufactured by the identified small businesses will not need to be remodeled in order to meet the proposed energy conservation standards. 
The primary value added by these 
small businesses is creating electric motors that fit the application specific purpose that the OEMs require. This includes combining an electric motor with specific mechanic couplings, weatherproofing, or controls to suit the OEM’s needs. Most small businesses manufacturer the motor housing and couplings, but do not manufacture the rotors and stators used in the electric motors they sell. While these small businesses may have to create new electric motor housings and/or couplings if the frame size or stack length of an electric motor changes in response to energy conservation standards, DOE was not able to identify any small businesses that own their own lamination dies sets and winding machines that are used to manufacture electric motor rotors and stators. 
The primary investment that electric 
motor manufacturers will have to make is to upgrade or replace lamination die 
sets and winding machines and to have engineers develop equipment designs to create more efficient electric motors. These investments (both capital and product conversion costs) would only be for electric motor manufacturers that manufacture electric motor rotors and stators. Electric motor manufacturers that do not manufacture the rotors and

10DOE estimated that it would take 
approximately three months of engineering time to 
redesign each electric motor housing. Based on data from BLS, the mean hourly wage of an electrical engineer is $51.87 (www.bls.gov/oes/current/ oes172071.htm) and wages comprise 70.5 percent of an employee’s total compensation (www.bls.gov/ 
news.release/archives/ecec_ 12152022.pdf). 
$51.87 (hourly wage) ÷ 0.705 (wage as a 
percentage of total compensation) = $73.57 (fully burdened hourly labor rate). $73.57 × 8 (hours in a workday) × 20 (working 
days in a month) × 3 (months) = $35,314. 
11app.avention.com. stators of an electric motor and instead 
purchase these components from other electric motor manufacturers would not need to purchase the machinery necessary to manufacture these components (i.e., would not need to 
purchase costly lamination dies sets and winding machines) nor would they need to spend R&D efforts to develop electric motor designs to meet energy conservation standards. Instead, these small manufacturers might have to create new moldings for larger electric motor housings (if the size of the motor core increases in response to energy 
conservation standards). DOE estimates the average small 
business would have to redesign four 
electric motor housings. DOE estimates this will cost approximately $50,000 in molding equipment per electric motor housing; $35,314 in engineering design effort per electric motor housing;
10and 
$10,000 in testing costs per electric motor housing. Based on these estimates, each electric motor housing that will need to be redesigned would cost small businesses approximately $95,314, or $381,254 to redesign four electric motor housings per small business. DOE displays in Table VI–1 the 
estimated average conversion costs per small business compared to the annual revenue for each small business. DOE used D&B Hoovers
11to estimate the 
annual revenue for each small business. Manufacturers will have 4 years between publication of the direct final rule and compliance with the energy conservation standards. Therefore, DOE presents the estimated conversion costs and testing costs as a percent of the estimated 4 years of annual revenue for each small business.

5. Duplication, Overlap, and Conflict 
With Other Rules and Regulations 
DOE is not aware of any rules or 
regulations that duplicate, overlap, or conflict with the rule being considered. 
6. Significant Alternatives to the Rule 
The discussion in the previous 
section analyzes impacts on small 
businesses that would result from DOE’s proposal, represented by TSL 2, as recommended in the November 2022 Joint Recommendation. In reviewing alternatives to the rule, DOE examined energy conservation standards set at lower efficiency levels. While TSL 1 would reduce the impacts on small business manufacturers, it would come at the expense of a reduction in energy savings. TSL 1 achieves 97 percent lower energy savings and 96 percent lower consumer NPV compared to the energy savings and consumer NPV at TSL 2. 
Based on the presented discussion, 
establishing standards at TSL 2 balances the benefits of the energy savings at TSL 2 with the potential burdens placed on electric motors manufacturers, including small business manufacturers. Accordingly, DOE does not adopt one of the other TSLs considered in the analysis. 
Additional compliance flexibilities 
may be available through other means. Manufacturers subject to DOE’s energy efficiency standards may apply to DOE’s Office of Hearings and Appeals for exception relief under certain circumstances. Manufacturers should refer to 10 CFR part 430, subpart E, and 10 CFR part 1003 for additional details. 
V. Public Participation A. Submission of Comments 
DOE will accept comments, data, and

(q) For purposes of determining the 
required minimum nominal full-load 
efficiency of an electric motor that has a horsepower or kilowatt rating between two horsepower or two kilowatt ratings listed in any table of energy conservation standards in paragraphs (n) through (p) through of this section, each such motor shall be deemed to have a listed horsepower or kilowatt rating, determined as follows: 
(1) A horsepower at or above the 
midpoint between the two consecutive horsepowers shall be rounded up to the higher of the two horsepowers; 
(2) A horsepower below the midpoint 
between the two consecutive horsepowers shall be rounded down to the lower of the two horsepowers; or 
(3) A kilowatt rating shall be directly 
converted from kilowatts to horsepower using the formula 1 kilowatt = (
1⁄0.746) 
horsepower. The conversion should be calculated to three significant decimal places, and the resulting horsepower shall be rounded in accordance with paragraphs (q)(1) or (2) of this section, whichever applies. 
(r) The standards in tables 8 through 
10 of this section do not apply to the following electric motors exempted by the Secretary, or any additional electric motors that the Secretary may exempt: 
(1) Component sets of an electric 
motor; 
(2) Liquid-cooled electric motors; 
(3) Submersible electric motors; and (4) Inverter-only electric motors.

the Federal Register a proposed rule to amend its regulation governing 
prudential management and operations standards, located at 12 CFR part 1236. See 88 FR 28433. The preamble 
discussion contains inadvertent typographical errors in reference to the regulation in sections II. and III.E. Sections II, and III.E. of the preamble discussions, therefore, should have referenced ‘‘the regulation’’ instead of ‘‘the proposed rule’’. There are no corrections to the proposed amendments to the regulation text in 12 CFR 1236 or to its appendix. For additional details on the proposed rulemaking, please see the May 4, 2023, Federal Register publication at 88 FR 28433.
