I. Authority and Background

A. Authority

    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 B of EPCA \2\ established the Energy 
Conservation Program for Consumer Products Other Than Automobiles, 
which sets forth a variety of provisions designed to improve energy 
efficiency, while Title III, Part C of EPCA,\3\ added by Public Law 95-
619, Title IV, section 441(a), established the Energy Conservation 
Program for Certain Industrial Equipment, which sets forth a variety of 
provisions designed to improve energy efficiency. These products and 
equipment include central air conditioners and heat pumps (``CAC/
HPs''), dishwashers (``DWs''), residential clothes washers (``RCWs''), 
pool heaters, dehumidifiers, external power supplies (``EPSs''), 
battery chargers, computer room air conditioners (``CRACs''), direct-
expansion dedicated outdoor air systems (``DX-DOASes''), air cooled, 
three-phase, small commercial air conditioners and heat pumps with a 
cooling capacity of less than 65,000 Btu/h and air-cooled, three-phase 
(``three-phase, less than 65,000 Btu/h ACUACs and ACUHPs''), variable 
refrigerant flow air conditioners and heat pumps with a cooling 
capacity of less than 65,000 Btu/h (``three-phase, less than 65,000 
Btu/h VRF''), commercial water heating equipment (``CWHs''), automatic 
commercial ice makers (``ACIMs''), walk-in coolers and walk-in freezers 
(``walk-ins''), commercial and industrial pumps, portable air 
conditioners (``portable ACs''), compressors, dedicated-purpose pool 
pump motors (``DPPPMs''), air cleaners, single package vertical units 
(``SPVUs''), and ceiling fan light kits (``CFLKs''), all of which are 
subjects of this document. (42 U.S.C. 6292(a)(3), (6-7), (11), and 
(20); 42 U.S.C. 6295(u), (cc), and (ff); 42 U.S.C. 6311(1)(A-D), (F-G), 
(K), and (2)(B)(i)).
---------------------------------------------------------------------------

    \1\ All references to EPCA in this document refer to the statute 
as amended through the Energy Act of 2020, Public Law 116-260 (Dec. 
27, 2020), which reflect the last statutory amendments that impact 
Parts A and A-1 of EPCA.
    \2\ For editorial reasons, upon codification in the U.S. Code, 
Part B was redesignated Part A.
    \3\ For editorial reasons, upon codification in the U.S. Code, 
Part C was redesignated Part A-1.
---------------------------------------------------------------------------

    The energy conservation program under EPCA consists essentially of 
four parts: (1) testing, (2) labeling, (3) Federal energy conservation 
standards, and (4) certification and enforcement procedures. Relevant 
provisions of EPCA specifically include definitions (42 U.S.C. 6291; 42 
U.S.C. 6311), test procedures (42 U.S.C. 6293; 42 U.S.C. 6314), 
labeling provisions (42 U.S.C. 6294; 42 U.S.C. 6315), energy 
conservation standards (42 U.S.C. 6295; 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).
    The Federal testing requirements consist of test procedures that 
manufacturers of covered products and equipment must use as the basis 
for: (1) certifying to DOE that their products or equipment comply with 
the applicable energy conservation standards adopted pursuant to EPCA 
(42 U.S.C. 6295(s); 42 U.S.C. 6316(a); 42 U.S.C. 6316(b); 42 U.S.C. 
6296), and (2) making other representations about the efficiency of 
those consumer products or industrial equipment (42 U.S.C. 6293(c); 42 
U.S.C. 6314(d)). Similarly, DOE must use these test procedures to 
determine whether the products or equipment comply with relevant 
standards promulgated under EPCA. (42 U.S.C. 6295(s); 42 U.S.C. 
6316(a); 42 U.S.C. 6316(b); 42 U.S.C. 6296).
    EPCA authorizes DOE to enforce compliance with the energy and water 
conservation standards established for covered products and equipment. 
(42 U.S.C. 6299-6305; 42 U.S.C. 6316(a)-(b)) DOE has promulgated 
certification and/or enforcement regulations that include reporting 
requirements for covered products and equipment including CAC/HPs, DWs, 
RCWs, pool heaters, dehumidifiers, EPSs, battery chargers, CRACs, 
three-phase, less than 65,000 Btu/h ACUACs and ACUHPs, three-phase, 
less than 65,000 Btu/h VRF, CWHs, ACIMs, walk-ins, commercial and 
industrial pumps, portable ACs, compressors, SPVUs, and CFLKs. DOE is 
proposing certification and reporting requirements for DX-DOASes, 
DPPPMs, and air cleaners. See 10 CFR part 429. Additionally, DOE is 
amending labeling requirements for walk-ins. See 10 CFR 431.305. The 
reporting requirements ensure that DOE has the information it needs to 
assess whether regulated products and equipment sold in the United 
States comply with the statutory and regulatory requirements applicable 
to each covered product and equipment type.

B. Background

    DOE's certification regulations are a mechanism that DOE uses to 
help ensure compliance with its regulations by collecting information 
about the energy and water use characteristics of covered products and 
covered equipment distributed in commerce in the United States. 
Manufacturers of most covered products and covered equipment must 
submit a certification report for the duration of distribution, 
specifically (1) before a basic model is distributed in commerce, (2) 
annually thereafter, and (3) if the basic model is redesigned in a 
manner that increases the consumption or decreases the efficiency of 
the basic model such that the certified rating is no longer supported 
by test data. 10 CFR 429.12. Additionally, manufacturers must report 
when production of a basic model has ceased and is no longer offered 
for sale as part of the next annual certification report following such 
cessation. 10 CFR 429.12(f). DOE requires the manufacturer of any 
covered product or covered equipment to establish, maintain, and retain 
the records of certification reports, of the underlying test data for 
all certification testing, and

[[Page 67460]]

of any other testing conducted to satisfy the requirements of 10 CFR 
part 429, 10 CFR part 430, and/or 10 CFR part 431 until 2 years after 
notifying DOE that a model has been discontinued. 10 CFR 429.71. 
Certification reports provide DOE and consumers with comprehensive, up-
to-date efficiency information and support effective enforcement.
    To ensure that all covered products and covered equipment 
distributed in the United States comply with DOE's energy and water 
conservation standards and reporting requirements, DOE has promulgated 
certification, compliance, and enforcement regulations in 10 CFR parts 
429 and 431. On March 7, 2011, DOE published in the Federal Register a 
final rule regarding certification, compliance, and enforcement for 
consumer products and commercial and industrial equipment, which 
revised, consolidated, and streamlined DOE's existing certification, 
compliance, and enforcement regulations for certain consumer products 
and commercial and industrial equipment covered under EPCA. See 76 FR 
12422. Since that time, DOE has completed multiple rulemakings 
regarding certification, compliance, and enforcement for specific 
covered products or equipment. See 79 FR 25486 (the May 5, 2014 Final 
Rule specific to certification of commercial and industrial heating, 
ventilation, and air conditioning (``HVAC''), refrigeration, and water 
heating equipment) and 87 FR 43952 (the July 22, 2022 Final Rule 
amending certification provisions for CFLKs, general service 
incandescent lamps, incandescent reflector lamps, ceiling fans, 
consumer furnaces and boilers, consumer water heaters, DWs, commercial 
clothes washers, battery charges, and DPPPMs).
    Additionally, if the Secretary has prescribed test procedures under 
section 6314 for any class of covered equipment, the Secretary shall 
prescribe a labeling rule applicable to such class of covered 
equipment. See 42 U.S.C. 6315(a). EPCA, however, also sets out certain 
criteria that must be met prior to prescribing a given labeling rule. 
Specifically, to establish these requirements, DOE must determine that: 
(1) labeling in accordance with section 6315 is technologically and 
economically feasible with respect to any particular equipment class; 
(2) significant energy savings will likely result from such labeling; 
and (3) labeling in accordance with section 6315 is likely to assist 
consumers in making purchasing decisions. (42 U.S.C. 6315(h))
    If these criteria are met, EPCA specifies certain aspects of 
equipment labeling that DOE must consider in any rulemaking 
establishing labeling requirements for covered equipment. At a minimum, 
such labels must include the energy efficiency of the affected 
equipment, as tested under the prescribed DOE test procedure, and may 
also require disclosure of the estimated operating costs and energy 
use. (42 U.S.C. 6315(b)) The labeling provisions shall include 
requirements the Secretary determines are likely to assist purchasers 
in making purchasing decisions, such as: requirements and directions 
for the display of the label; requirements for including on any label, 
or separately attaching to, or shipping with, the covered equipment, 
such additional information related to energy efficiency, energy use, 
and other measures of energy consumption, including instructions for 
maintenance and repair of the covered equipment, as the Secretary 
determines is necessary to provide adequate information to purchasers; 
and requirements that printed matter displayed or distributed with the 
equipment at the point of sale also include the information required to 
be placed on the label. (42 U.S.C. 6315(c))

II. Synopsis of the Notice of Proposed Rulemaking

    Since the previous final rule amending certification requirements 
for covered products (July 22, 2022; 87 FR 43952), DOE has proposed or 
finalized test procedures and/or energy conservation standards for 
multiple products and equipment. In this rulemaking, DOE is proposing 
to revise its certification, labeling, and enforcement regulations for 
certain covered products and equipment to align with these proposed and 
finalized amendments.
    In this notice of proposed rulemaking (``NOPR''), DOE proposes to 
update the certification reporting requirements as follows:
    (1) CAC/HP. Update the CAC/HP certification reporting requirements 
at 10 CFR 429.16 to reflect the current version of the test procedure 
at appendix M1 to subpart B of 10 CFR part 430 (``appendix M1'') 
including test condition information. Correct discrepancies in CAC/HP 
sampling plan to require using Student's t-Distribution Values from 
appendix A to subpart B of part 429.
    (2) DW. Align the DW certification reporting requirements with 
appendix C1 to subpart B of 10 CFR part 430 (``appendix C1''), and with 
appendix C2 to subpart B of 10 CFR part 430 (``appendix C2''). 
Manufacturers must use appendix C1 beginning July 17, 2023. If DOE 
adopts any amended energy conservation standards based on appendix C2, 
manufacturers must use appendix C2 beginning on the standards' 
compliance date. Add reporting requirements specific to the energy and 
water use for DWs with water re-use systems and built-in reservoirs.
    (3) RCWs. Remove outdated certification reporting requirements for 
RCWs pertaining to appendix J1 to subpart B of 10 CFR part 430 
(``appendix J1''), which has been removed. Update the existing 
certification reporting requirements pertaining to appendix J2 to 
subpart B of 10 CFR part 430 (``appendix J2'') for consistency with 
test procedure terminology. Add a reporting requirement for test cloth 
lot used by a manufacturer for testing/certifying to align with RCW 
enforcement provisions outlined in 10 CFR 429.134(c). Add new 
certification reporting requirements specific to appendix J to subpart 
B of 10 CFR part 430 (``appendix J''), use of which would be required 
at such time as compliance is required with any amended energy 
conservation standards based on appendix J.
    (4) Pool heaters. Align pool heater certification reporting 
requirements with the amended energy conservation standards established 
in a final rule published on May 30, 2023 (88 FR 34624) to require 
reporting of thermal efficiency for electric pool heaters and establish 
new reporting requirements specific to electric pool heaters.
    (5) Dehumidifiers. Remove outdated certification reporting 
requirements for dehumidifiers pertaining to appendix X to subpart B of 
10 CFR part 430 (``appendix X''), use of which is no longer required.
    (6) EPSs. Align EPS certification reporting requirements with the 
amended test procedure at appendix Z to subpart B of 10 CFR part 430 
(``appendix Z''), use of which is required beginning February 15, 2023. 
Add reporting requirements to specify the output cord shipped with the 
EPS (or the manufacturer's recommended output cord specifications). 
Update the existing EPS certification reporting requirements to align 
with the energy conservation standards established in the February 10, 
2014 final rule (79 FR 7845), and require output voltage, which is 
needed to verify the applicable product class. Revise sales reporting 
requirements for EPSs exempt from energy conservation standards to 
include the years for which the sales number represents.

[[Page 67461]]

    (7) Battery chargers. Align battery charger certification reporting 
requirements with appendix Y1 to subpart B of 10 CFR part 430 
(``appendix Y1''), use of which would be required for any future 
amended energy conservation standards for battery chargers.
    (8) CRACs. Align CRACs certification reporting requirements with 
amended energy conservation standards established in a final rule 
published in the Federal Register on June 2, 2023 (88 FR 36392) and

format. Establish alternative efficiency determination method 
(``AEDM'') tolerances for CRAC verification tests for NSenCOP.
    (9) DX-DOAS. Establish DX-DOAS certification reporting requirements 
for certifying compliance with the energy conservation standards 
established in the November 1, 2022 final rule (87 FR 65651), 
compliance with which is required beginning May 1, 2024. Require 
submission of a supplemental testing instructions file in PDF format.
    (10) Commercial AC/HPs. Establish certification reporting 
requirements for three-phase, less than 65,000 Btu/h ACUACs and ACUHPs 
and three-phase, less than 65,000 Btu/h VRF aligned with the energy 
conservation standards established in the final rule published on June 
2, 2023 (88 FR 36392), compliance with which would be required 
beginning January 1, 2025. Correct discrepancies in sampling plan for 
three-phase, less than 65,000 Btu/h ACUACs and ACUHPs and three-phase, 
less than 65,000 Btu/h VRF to specify that the Student's t-Distribution 
Values from appendix A to subpart B of part 429 should be used.
    (11) CWHs. Align CWH certification reporting requirements with 
amended energy conservation standards proposed in the May 19, 2022 NOPR 
(87 FR 30610). Add reporting requirements specific to commercial

Correct ACIM sampling requirements to remove discrepancy and require 
using the Student's t-Distribution Values for a 95 percent one-tailed 
confidence interval.
    (13) WICFs. For walk-in refrigeration systems, add requirement to 
report whether each refrigeration system meets the definition of a 
carbon dioxide (``CO2'') unit cooler, detachable single-packaged 
dedicated system, or an attached split system, consistent with 
amendments to 10 CFR 431.302. Add requirements for submission of 
supplementary testing information if necessary to run a valid test and 
provide an option to report any compressor break-in duration used to 
obtain certified rating. Additionally, expand the certification 
reporting requirements for walk-in cooler and freezers with anti-sweat 
heater (``ASH'') doors. Revise labeling requirements for walk-in panels 
and walk-in refrigeration systems at 10 CFR 431.305.

------------------------------------------------------------------------

    The proposed regulatory amendments summarized in this section, and 
that are described in greater detail in section III, pertain to 
certification reporting requirements only. DOE is not proposing 
amendments to the test procedures or energy conservation standards for 
CAC/HPs, DWs, RCWs, pool heaters, dehumidifiers, EPSs, battery 
chargers, CRACs, DX-DOASes, three-phase, less than 65,000 Btu/h ACUACs 
and ACUHPs, three-phase, less than 65,000 Btu/h VRF, CWHs, ACIMs, 
WICFs, commercial and industrial pumps, portable ACs, compressors, 
DPPPMs, air cleaners, SPVUs, and CFLKs.

III. Discussion

    Certification of compliance to DOE is a mechanism that helps 
manufacturers understand their regulatory obligations for distributing 
basic models of covered products and equipment that are subject to 
energy conservation standards. Certification also helps consumers 
obtain information about products' energy performance. Certification 
reports include characteristics of covered products or equipment used 
to determine which standard applies to a given basic model, and they 
also help DOE identify models and/or regulated entities that may not 
comply with the applicable regulations.
    For the covered products and equipment addressed in this NOPR, DOE 
has identified areas in which the certification reporting requirements 
in 10 CFR part 429 are not consistent with the information required to 
verify whether the information provided is consistent with the 
certifier's statement of compliance with current energy conservation 
standards. DOE is proposing amendments to the certification and 
reporting provisions for these products and equipment to ensure 
reporting that is consistent with currently applicable energy 
conservation standards and to ensure that DOE has the information 
necessary to determine the appropriate classification of products for 
the application of standards. In addition to the specific proposals 
discussed in the following sections, DOE is also proposing minor 
amendments to ensure consistency among terms used throughout DOE's 
certification and reporting provisions. Additionally, DOE is proposing 
labeling requirements for certain covered equipment.

A. Central Air Conditioners and Heat Pumps

    DOE is proposing to amend the certification reporting requirements 
for CAC/HPs. A central air conditioner or central air conditioning heat 
pump means a product, other than a packaged terminal air conditioner or 
packaged terminal heat pump, which is powered by single phase electric 
current, air cooled, rated below 65,000 Btu/h, not contained within the 
same cabinet as a furnace, the rated capacity of which is above 225,000 
Btu/h, and is a heat pump or a cooling unit only. A central air 
conditioner or central air conditioning heat pump may consist of: a 
single-package unit; an outdoor unit and one or more indoor units; an 
indoor unit only; or an outdoor unit with no match. In the case of an 
indoor unit only or an outdoor unit with no match, the unit must be 
tested and rated as a system (combination of both an indoor and an 
outdoor unit). 10 CFR 430.2.
    On October 25, 2022, DOE published a final rule (``October 2022 
CAC/HP Final Rule'') in which DOE amended the test procedure provisions 
for CAC/HPs. 87 FR 64550. Consistent with that final rule, DOE is 
proposing amendments to the reporting requirements.

1. Reporting
    Under the existing requirements in 10 CFR 429.16, manufacturers of 
CAC/HPs must report a variety of values and information, including 
seasonal energy efficiency ratio 2 (``SEER2'') in Btu/W-h, average off 
mode power consumption, cooling capacity in Btu/h, and heating seasonal 
performance factor 2 (``HSPF2'') in Btu/W-h. 10 CFR 429.16(e)(2) For a 
complete list of existing certification reporting requirements, see 10 
CFR 429.16(e). These requirements provide for certifying compliance 
with the current standards applicable to CAC/HP equipment manufactured 
on or after January 1, 2023. 10 CFR 430.32(c). DOE is proposing to 
update these requirements and align the reporting requirements with the 
appendix M1 test procedure and proposing general certification 
requirements for CAC/HPs. DOE discusses these proposed updates in the 
following sections.
a. Variable Speed Coil-Only Rating Based on Non-Communicating or 
Communicating Control
    In the October 2022 CAC/HP Final Rule, DOE defined a 
``communicating variable-speed coil-only central air conditioner or 
heat pump'' as a variable-speed compressor system having a coil-only 
indoor unit that is installed with a control system that (a) 
communicates the difference in space temperature and space setpoint 
temperature (not a setpoint value inferred from on/off thermostat 
signals) to the control that sets compressor speed; (b) provides a 
signal to the indoor fan to set fan speed appropriate for compressor 
staging and air volume rate; and (c) has installation instructions 
indicating that the required control system meeting both (a) and (b) 
must be installed. 87 FR 64550, 64560.
    DOE defined a ``variable-speed non-communicating coil-only central 
air conditioner or heat pump'' as a variable-speed compressor system 
having a coil-only indoor unit that does not meet the definition of 
variable-speed communicating coil-only central air conditioner or heat 
pump. Id.
    In the October 2022 CAC/HP Final Rule, DOE elaborated that 
variable-speed coil-only systems that meet the ``communicating'' 
definition should be tested like any other variable-speed system, 
except that the heating full-load air volume rate should be equal to 
the cooling full-load air volume rate and the intermediate and minimum 
cooling and heating air volume rates should all be higher than (1) the 
rate specified by the installation instructions included with the unit 
by the manufacturer, and (2) 75 percent of the full-load cooling air 
volume rate. Id.
    Because this aspect of the basic model's operating characteristics 
determines the way it must be tested, manufacturers need to certify 
whether a variable speed coil-only rating is based on non-communicating 
or communicating control. Therefore, DOE is proposing to include this 
requirement in the certification template.
    DOE seeks comment on its proposal to require reporting of whether a 
variable speed coil-only rating is based on non-communicating or 
communicating control.
b. Air Volume Rate Changing With Outdoor Conditions
    In the October 2022 CAC/HP Final Rule, DOE explained that 
requirements for setting air volume rate in section 3.1.4 of appendix 
M1 may conflict with instructions to use air volume rates that 
represent a ``normal installation'' in section 3.2, particularly for 
modern blower-coil systems with multiple-speed or variable-speed indoor 
fans and control systems, which may change air volume rate in response 
to operating conditions such as outdoor air temperature. 87 FR 64550, 
64569. To address this issue, in the October 2022 CAC/HP Final Rule, 
DOE explicitly stated in step 7 of sections 3.1.4.1.1.a, 3.1.4.2.a, and 
3.1.4.3.a of appendix M1 that, for blower-coil systems in which the 
indoor blower capacity modulation correlates with outdoor dry bulb 
temperature or sensible-to-total cooling capacity ratio, use an air 
volume rate that represents a normal operation. Id. Also, DOE indicated 
that to ensure consistency of testing, it may be necessary for 
manufacturers to certify whether the system varies blower speeds with 
outdoor air conditions. Id.
    For these reasons, DOE is proposing that manufacturers include in 
their certification whether the system varies blower speeds with 
outdoor air conditions.
    DOE seeks comment on its proposal to require reporting of whether a 
CAC/HP system varies blower speeds with outdoor air conditions.
c. Sampling Corrections
    Currently, DOE's sampling provisions for CAC/HPs state that any 
represented value of power consumption or other measure of consumption 
of a basic model for which consumers would favor lower values shall be 
greater than or equal to the higher of the mean of the sample, or the 
upper 90 percent confidence limit of the true mean (``UCL'') divided by 
1.05. 10 CFR 429.16(b)(3)(i). Additionally, the sampling provisions 
state that any represented value of the energy efficiency, cooling 
capacity, heating capacity or other measure of energy consumption for 
which consumers would favor higher values shall be less than or equal 
to the lower of the mean of the sample, or the lower 90 percent 
confidence limit of the true mean (``LCL'') divided by 0.95. 10 CFR 
429.16(b)(3)(ii)-(iii). The sampling provisions also state that the UCL 
and LCL should be calculated using the Student's t-Distribution Values 
for a 90 percent one-tailed confidence interval with n-1 degrees of 
freedom from appendix D to subpart B of part 429 (``appendix D''), 
where ``n'' is the number of samples. 10 CFR 429.16(b)(3)(i)-(iii). 
However, the Appendix containing Student's t-Distribution Values has 
moved to appendix A to subpart B of part 429 (``Appendix A'') and is no 
longer located at appendix D.\4\.''). To correct this discrepancy, DOE 
is proposing to revise 10 CFR 429.16(b)(3)(i)-(iii) to specify that the 
UCL and LCL should be calculated using the Student's t-Distribution 
Values for a 90 percent one-tailed confidence interval outlined in 
appendix A.
---------------------------------------------------------------------------

    \4\ Appendix D now contains the sampling plan for enforcement 
testing of Uninterruptible Power Supplies
---------------------------------------------------------------------------

    DOE seeks comment on its proposal to correct the sampling 
provisions for CAC/HPs to reference appendix A instead of appendix D.
2. Reporting Costs and Impacts
    As described in the previous section, DOE proposes in this NOPR to 
align CAC/HP certification reporting requirements with the current test 
procedure for CAC/HP in appendix M1, which was most recently amended by 
the October 2022 CAC/HP Final Rule. The proposed certification 
requirements in this proposed rule specifically address new provisions 
in this amended version of the appendix M1 test procedure, use of which 
was required beginning on April 24, 2023.
    DOE has tentatively determined that these proposed amendments to 
the certification requirements would not impose additional costs for 
manufacturers because manufacturers of CAC/HPs are already submitting 
certification reports to DOE and should have readily available the 
information that DOE is proposing to collect as part of this 
rulemaking. DOE does not believe the revised reporting requirements 
will cause any appreciable change in reporting burden or hours as 
compared to what CAC/HP

[[Page 67466]]

manufacturers are currently doing today.
    DOE requests comment on the certification reporting costs of the 
amendments proposed for CAC/HPs.

B. Dishwashers

    DOE is proposing to amend the certification reporting requirements 
for DWs, which are cabinet-like appliances which, with the aid of water 
and detergent, wash, rinse, and dry (when a drying process is included) 
dishware, glassware, eating utensils, and most cooking utensils by 
chemical, mechanical and/or electrical means and discharge to the 
plumbing drainage system. 10 CFR 430.2. In the DWs test procedure final 
rule published on January 18, 2023 (``January 2023 DW Final Rule''), 
DOE amended the existing DWs test procedure at appendix C1 and 
established a new test procedure at appendix C2, which would be 
required at the time compliance is required with any amended energy and 
water conservation standards. 88 FR 3234. Consistent with that final 
rule, DOE is proposing amendments to the reporting requirements.
1. Reporting
    Under the existing requirements in 10 CFR 429.19, manufacturers 
must report the following public product-specific information: the 
estimated annual energy use in kilowatt hours (``kWh'') per year 
(``kWh/yr''), the water consumption in gallons per cycle, and the 
capacity in number of place settings as specified in ANSI/AHAM DW-1-
2010.\5\ 10 CFR 429.19(b)(2). Manufacturers must additionally report 
the following product-specific information: the presence of a soil 
sensor (and if present, the number of cycles required to reach 
calibration); water inlet temperature used for testing in degrees 
Fahrenheit (``[deg]F''); cycle selected for the energy test and whether 
that cycle is soil-sensing; the options selected for the energy test; 
the presence of a built-in water softening system (and if present, the 
energy use in kWh and the water use in gallons required for each 
regeneration of the water softening system, the number of regeneration 
cycles per year, and data and calculations used to derive these 
values); and an indication of whether Cascade Complete powder was used 
as the detergent formulation in lieu of Cascade with the Grease 
Fighting Power of Dawn powder. 10 CFR 429.19(b)(3). These requirements 
are applicable for any DW distributed in the United States on or after 
May 30, 2013. Additionally, in a test procedure final rule published on 
July 27, 2023 (``July 2023 DW Final Rule''), DOE updated the detergent 
formulation reporting requirement at 10 CFR 429.19(b)(3)(vi) as 
follows: indication of whether Cascade Complete Powder or Cascade with 
the Grease Fighting Power of Dawn was used as the detergent 
formulation. 88 FR 48351. For dishwashers other than water re-use 
dishwashers, the July 2023 DW Final Rule additionally specified that 
before July 17, 2023, Cascade Complete Powder detergent may be used as 
the basis for certification in conjunction with the detergent dosing 
methods specified in either section 2.5.2.1.1 or section 2.5.2.1.2 of 
appendix C1 as amended in the July 2023 DW Final Rule and Cascade with 
the Grease Fighting Power of Dawn detergent may be used as the basis 
for certification only in conjunction with the detergent dosing 
specified in section 2.5.2.1.1 of appendix C1 as amended in the July 
2023 DW Final Rule. Further, for dishwashers other than water re-use 
dishwashers, the July 2023 DW Final Rule specified that beginning July 
17, 2023, Cascade Complete Powder detergent may be used as the basis 
for certification of newly certified basic models only in conjunction 
with the detergent dosing method specified in section 2.5.2.1.2 of 
appendix C1 as amended in the July 2023 DW Final Rule and Cascade with 
the Grease Fighting Power of Dawn detergent may be used as the basis 
for certification only in conjunction with the detergent dosing 
specified in section 2.5.2.1.1 of appendix C1 as amended in the July 
2023 DW Final Rule. The July 2023 DW Final Rule additionally specified 
that manufacturers may maintain existing basic model certifications 
made prior to July 17, 2023, consistent with the provisions of Sec.  
429.19(b)(3)(vi)(A) and (B). Id.

    \5\ American National Standards Institute/Association of Home 
Appliance Manufacturers DW-1-2010: Household Electric Dishwasher.
---------------------------------------------------------------------------

    DOE is proposing to update the dishwasher certification reporting 
requirements and align the reporting requirements with the amended test 
procedure at appendix C1 and the new test procedure at appendix C2. Use 
of appendix C2 would be required when determining compliance with any 
future amended energy and water conservation standards. Appendix C2 to 
subpart B of part 430. Accordingly, the certification reporting 
requirements that are specific to appendix C2 would be required only at 
such time as use of appendix C2 is required to demonstrate compliance 
with any future amended energy and water conservation standards. DOE 
discusses the proposed updates in the following sections.
a. Update to the AHAM Industry Standard
    The current reporting requirements at 10 CFR 429.19(b)(2) reference 
the industry standard, ANSI/AHAM DW-1-2010 to the capacity of a 
dishwasher in number of place settings. DOE is proposing to exclude 
this reference in the dishwasher reporting requirements at 10 CFR 
429.19 because this industry standard is now obsolete. Additionally, 
the reference to the definition of place settings only includes the 
items in the test load that comprise a single place setting; it does 
not define the capacity of a dishwasher itself, which is the metric 
that needs to be reported for dishwashers at 10 CFR 429.19(b)(2). 
Relatedly, DOE also proposes to remove ANSI/AHAM DW-1-2010 from its 
list of materials incorporated by reference at 10 CFR 429.4 because 
this standard would no longer be referenced anywhere in 10 CFR part 429 
after the proposed removal of this reference from 10 CFR 429.19.
    DOE requests comment on its proposal to remove ANSI/AHAM DW-1-2010 
from the referenced industry standard in 10 CFR 429.19(b)(2).
b. Cycle Selected for Energy Test
    In the January 2023 DW Final Rule, DOE established a new appendix 
C2 that specifies, in part, a minimum cleaning index threshold as a 
condition for a valid test cycle. 88 FR 3234. If the normal cycle at 
any soil level (i.e., heavy, medium, or light) does not meet the 
specified cleaning index threshold, the unit is tested at the most 
energy-intensive cycle that can achieve a cleaning index threshold of 
70. 88 FR 3234, 3266. To ensure that the certification template is 
consistent with the tested cycle requirements specified in appendix C2, 
DOE proposes to include the following additional confidential reporting 
requirement at 10 CFR 429.19(b)(3)(iii): the cycle selected for the 
energy test at the heavy, medium, and light soil loads and whether 
these cycles are soil-sensing. Further, DOE proposes to include the 
following additional confidential reporting requirement at 10 CFR 
429.19(b)(3)(iv): the options selected for the energy test at the 
heavy, medium, and light soil loads. These reporting requirements would 
be required only at such time as use of appendix C2 is required to 
demonstrate compliance with any future amended energy and water 
conservation standards.
    DOE requests comment on the proposed requirement to confidentially

[[Page 67467]]

report the cycle selected for the energy test at the heavy, medium, and 
light soil loads and whether these cycles are soil-sensing as well as 
the options selected for the energy test at the heavy, medium, and 
light soil loads when testing according to appendix C2.
c. Cleaning Index
    As noted previously, the January 2023 DW Final Rule established a 
new appendix C2 that specifies a minimum cleaning index threshold as a 
condition for a valid test cycle. 88 FR 3234. Specifically, the January 
2023 DW Final Rule states that each tested cycle on each individual 
unit is required to achieve the applicable cleaning index threshold to 
constitute a valid test cycle. 88 FR 3234, 3265-3266. To ensure that 
the reported test cycle is a valid test cycle that meets the specified 
applicable cleaning index threshold, DOE is proposing a confidential 
reporting requirement for the cleaning index of the sensor heavy 
response, sensor medium response, and sensor light response test 
cycles. DOE additionally proposes that the reported cleaning index for 
each basic model must be the average cleaning index of the individual 
test units at each soil level. This reporting requirement would be 
required only at such time as use of appendix C2 is required to 
demonstrate compliance with any future amended energy and water 
conservation standards.
    DOE requests comment on the proposed requirement to confidentially 
report the average cleaning index of the sensor heavy response, sensor 
medium response, and sensor light response test cycles.
d. Water Re-Use System Dishwashers
    On November 1, 2013, DOE published a Decision and Order granting 
Whirlpool a test procedure waiver (``Whirlpool waiver'') for testing 
specified basic models equipped with a ``water use system,'' in which 
water from the final rinse cycle is stored for use in the subsequent 
cycle, with periodic draining (``drain out'') and cleaning (``clean 
out'') events. 78 FR 65629, 65629-65630. (Case No. DW-11).\6\
---------------------------------------------------------------------------

    \6\ All materials regarding the Whirlpool waiver are available 
in docket EERE-2013-BT-WAV-0042 at www.regulations.gov.
---------------------------------------------------------------------------

    In the January 2023 DW Final Rule, DOE amended appendix C1 to 
include the requirements from the Whirlpool waiver for testing water 
re-use system DWs via reference to the industry standard, AHAM DW-1-
2020, with some modifications to the equations in sections 5.6.1.3, 
5.6.1.4, 5.6.2.3, and 5.6.2.4 of AHAM DW-1-2020. DOE also adopted these 
requirements in the new appendix C2. 88 FR 3234, 3249.
    Accordingly, DOE proposes to amend the reporting requirements at 10 
CFR 429.19(b)(3) to include reporting of energy and water use 
associated with drain out and clean out events, consistent with the 
information required to be reported by Whirlpool as part of the waiver. 
These reported values would be used in equations to account for the 
extra water and energy associated with water re-use systems. 
Specifically, DOE is proposing that the additional machine electrical 
energy consumption required for a drain out event and clean out event--
expressed in kWh--and the additional water consumption required for 
drain out and clean out events during a drain out cycle--expressed in 
gallons per cycle (``gal/cycle'')--be reported confidentially.
    DOE seeks comment on its proposal to require that additional 
machine electrical energy consumption required for a drain out event 
and clean out event--expressed in kWh--and the additional water 
consumption required for drain out and clean out events during a drain 
out cycle--expressed in gal/cycle--be reported confidentially.
e. Dishwashers With Built-In Reservoirs
    DOE published a Decision and Order on December 9, 2020 granting CNA 
International Inc. (``CNA'') a test procedure waiver (``CNA waiver'') 
for a basic model of a compact DW that does not connect to a water 
supply line and instead has a built-in reservoir that must be manually 
filled with water. 85 FR 79171, 79171 and 79173 (Case No. 2020-008).\7\
---------------------------------------------------------------------------

    \7\ All materials regarding the CNA waiver are available in 
docket EERE-2020-BT-WAV-0024 at www.regulations.gov.
---------------------------------------------------------------------------

    In the January 2023 DW Final Rule, DOE amended appendix C1 to 
include the requirements from the CNA waiver, which was specific to a 
compact DW basic model, to be applicable to a DW of any capacity with a 
manually filled built-in water reservoir. DOE also adopted these 
requirements in the new appendix C2. 88 FR 3234, 3241.
    Accordingly, DOE proposes to amend the reporting requirements at 10 
CFR 429.19(b)(3) to include reporting of the reservoir capacity in 
gallons, prewash and main wash fill water volume in gallons (if testing 
is performed using appendix C1), and the total water consumption in 
gallons per cycle for DWs with built-in reservoirs. DOE's proposal to 
report the prewash and main wash fill water volumes is only applicable 
to appendix C1 because these water volumes are used to determine 
detergent dosage in appendix C1, while the detergent dosage in appendix 
C2 is dependent on the number of place settings.
    DOE seeks comment on its proposal to require reporting of reservoir 
capacity in gallons, prewash and main wash fill water volume in gallons 
(if testing is performed using appendix C1), and the total water 
consumption in gallons per cycle for DWs with built-in reservoirs.
f. Rounding Requirements
    DOE proposes to specify at new section 10 CFR 429.19(c) that the 
represented value of estimated annual energy use must be rounded to the 
nearest kWh/yr and the represented value of water consumption must be 
rounded to one decimal place, i.e., the nearest 0.1 gallon per cycle. 
These rounding requirements are consistent with the existing rounding 
requirements for DWs specified at 10 CFR 430.23(c)(2) and 10 CFR 
430.23(c)(3), respectively.
    DOE requests comment on the proposed rounding requirements for DWs.
2. Reporting Costs and Impacts
    In this NOPR, DOE proposes to align the DW certification reporting 
requirements with the amended test procedure at appendix C1, use of 
which is required beginning July 17, 2023, and with the newly adopted 
test procedure at appendix C2, use of which would be required at such 
time as compliance is required with any amended energy conservation 
standards based on appendix C2.
    For dishwashers, manufacturers currently report the following: (1) 
the estimated annual energy use in kWh/yr; (2) the water consumption in 
gallons per cycle; (3) the capacity in number of place settings as 
specified in ANSI/AHAM DW-1-2010; (4) the presence of a soil sensor, 
and if present, the number of cycles required to reach calibration; (5) 
the water inlet temperature used for testing in [deg]F; (6) the cycle 
selected for the energy test and whether that cycle is soil-sensing; 
(7) the options selected for the energy test; and (8) the presence of a 
built-in water softening system, and if present, the energy use in kWh 
and the water use in gallons required for each regeneration of the 
water softening system, the number of regeneration cycles per year, and 
data and calculations used to derive these values. 10 CFR 429.19 
(b)(2)-(3). Manufacturers also report whether Cascade Complete powder 
was used as the detergent formulation in lieu of Cascade with the

[[Page 67468]]

Grease Fighting Power of Dawn powder. 10 CFR 429.19(b)(3)(vi). 
Beginning August 28, 2023, the effective date of the July 2023 DW Final 
Rule, the reporting requirement pertaining to the detergent formulation 
would be updated such that manufacturers would be required to report 
whether Cascade Complete Powder or Cascade with the Grease Fighting 
Power of Dawn was used as the detergent formulation. 88 FR 48351, 
48357. Additionally, when certifying dishwashers, other than water re-
use dishwashers, according to appendix C1, the following requirements 
would be applicable: (A) Before July 17, 2023, Cascade Complete Powder 
detergent may be used as the basis for certification in conjunction 
with the detergent dosing methods specified in either section 2.5.2.1.1 
or section 2.5.2.1.2 of appendix C1. Cascade with the Grease Fighting 
Power of Dawn detergent may be used as the basis for certification only 
in conjunction with the detergent dosing specified in section 2.5.2.1.1 
of appendix C1. (B) Beginning July 17, 2023, Cascade Complete Powder 
detergent may be used as the basis for certification of newly certified 
basic models only in conjunction with the detergent dosing method 
specified in section 2.5.2.1.2 of appendix C1. Cascade with the Grease 
Fighting Power of Dawn detergent may be used as the basis for 
certification only in conjunction with the detergent dosing specified 
in section 2.5.2.1.1 of appendix C1. Manufacturers may maintain 
existing basic model certifications made prior to July 17, 2023, 
consistent with the provisions of paragraph 10 CFR 429.19(b)(3)(vi)(A). 
Id.
    Under the proposed amendments, if adopted, manufacturers would 
additionally report the following: (1) the cycles selected for the 
sensor heavy response, sensor medium response, and sensor light 
response and whether these cycles are soil-sensing if testing is 
performed using appendix C2; (2) the options selected for the sensor 
heavy response, sensor medium response, and sensor light response if 
testing is performed using appendix C2; (3) the average cleaning index 
for the sensor heavy response, sensor medium response, and sensor light 
response cycles if testing is performed using appendix C2; (4) whether 
the product is a water re-use system dishwasher and if so, the energy 
use in kWh and water use in gallons required for a drain out event, the 
energy use in kWh and water use in gallons required for a clean out 
event, the number of drain out events per year, the number of clean out 
events per year, the water fill volume to calculate detergent dosage in 
gallons, and data and calculations used to derive these values, as 
applicable; and (5) the presence of a built-in reservoir and if 
present, the manufacturer-stated reservoir capacity in gallons, the 
prewash fill water volume in gallons and the main wash fill water 
volume in gallons if testing is performed using appendix C1, and the 
reservoir water consumption in gallons per cycle. DOE is additionally 
proposing to add rounding requirements for estimated annual energy use 
and water consumption and remove the ANSI/AHAM DW-1-2010 industry 
standard that is included as a reference from 10 CFR 429.4.
    DOE has tentatively determined that these proposed amendments would 
not impose additional costs for manufacturers because manufacturers of 
DWs are already submitting certification reports to DOE and should have 
readily available the information that DOE is proposing to collect as 
part of this rulemaking. Additionally, any requirements stemming from 
the updates to the test procedure were accounted for in the January 
2023 Final Rule. DOE does not believe the revised reporting 
requirements will cause any appreciable change in reporting burden or 
hours as compared to what DW manufacturers are currently doing today.
    DOE requests comment on the certification reporting costs of the 
amendments proposed for DWs.

C. Residential Clothes Washers

    DOE is proposing to amend the reporting requirements for RCWs, 
which are a consumer product designed to clean clothes, utilizing a 
water solution of soap and/or detergent and mechanical agitation or 
other movement, that must be one of the following classes: automatic 
clothes washers, semi-automatic clothes washers, and other clothes 
washers. 10 CFR 430.2. In the RCWs test procedure final rule published 
on June 1, 2022 (``June 2022 RCW Final Rule''), DOE amended the 
existing RCWs test procedure at appendix J2, established a new test 
procedure at appendix J, which would be required at the time compliance 
is required with any amended energy and water conservation standards, 
and removed appendix J1. 87 FR 33316. Consistent with the June 2022 RCW 
Final Rule, DOE is proposing amendments to the reporting requirements.
1. Reporting
    Under the existing requirements in 10 CFR 429.20(b)(2)(i), 
manufacturers of RCWs tested in accordance with the test procedure at 
appendix J1 must report: the modified energy factor (``MEF''), the 
capacity, the corrected moisture content (``RMC''), and the integrated 
water factor (``IWF''). Under the existing requirements in 10 CFR 
429.20(b)(2)(ii), manufacturers of RCWs tested in accordance with the 
test procedure at appendix J2 must report: the integrated modified 
energy factor (``IMEF''), the IWF, the capacity, the RMC, and the type 
of loading (top-loading or front-loading). Under the existing 
requirements in 10 CFR 429.20(b)(3), all manufacturers of RCWs must 
also report a list of cycle selections comprising the complete energy 
test cycle.
    DOE is proposing to update these requirements and to specify new 
reporting requirements that would apply to the new appendix J test 
procedure and that would be required for certifying compliance only at 
such time as use of appendix J is required. DOE discusses these 
proposed updates in the following sections.
a. Removing Appendix J1
    Appendix J1 was removed from the CFR as part of the June 2022 RCW 
Final Rule. 87 FR 33316, 33365. Therefore, the provisions in 10 CFR 
429.20(b)(2)(i), which specify reporting requirements for RCWs tested 
in accordance with appendix J1, are obsolete. For these reasons, DOE 
proposes to remove these reporting requirements.
    DOE requests comment on its proposal to remove reporting 
requirements applicable to appendix J1 from 10 CFR 429.20(b)(2)(i).
b. Clothes Container Capacity
    DOE has established separate product classes for RCWs based on 
clothes container capacity, among other characteristics. 10 CFR 
430.32(g)(4) The current test procedure uses the term ``clothes 
container capacity'' to refer to the measured capacity (see section 3.1 
of appendix J2), whereas the current reporting requirements at 10 CFR 
429.20(b)(2) use the term ``capacity.'' To provide greater consistency 
in terminology between the test procedure and the reporting 
requirements, DOE proposes to update the reporting requirement 
terminology from ``capacity'' to ``clothes container capacity.''
    DOE requests comment on its proposal to update reporting 
requirement terminology to specify ``clothes container capacity for 
RCWs.

[[Page 67469]]

c. Test Cloth Lot Number
    In the June 2022 RCW Final Rule, DOE implemented new language in 10 
CFR 429.134(c) that provides additional product-specific enforcement 
provisions for clothes washers to accommodate differences in RMC values 
that may result from DOE using a different test cloth lot than was used 
by the manufacturer for testing and certifying the basic model. 87 FR 
33316, 33369-33371. To implement this new enforcement provision, DOE 
proposes to require reporting the test cloth lot number used during 
certification testing. DOE also proposes that the reported test cloth 
lot number would not be public.
    DOE requests comment on its proposal to require the reporting of 
the test cloth lot number for RCWs for the purpose of implementing the 
enforcement provisions in 10 CFR 429.134(c), as well as its proposal 
that the reported test cloth lot number would not be public.
d. Specifying Requirements for Appendix J
    The new appendix J test procedure establishes new energy and water 
efficiency metrics for RCWs. Use of appendix J would be required at 
such time as compliance is required with any amended energy 
conservation standards based on these new metrics as measured using 
appendix J. 87 FR 33316. On March 3, 2023, DOE proposed amended 
standards for clothes washers based on the new metrics as measured 
using appendix J. 88 FR 13520. Consistent with these new metrics, DOE 
proposes to specify certification requirements at 10 CFR 
429.20(b)(2)(i) corresponding to the use of appendix J, as detailed in 
the following sections. These reporting requirements would be required 
only at such time as use of appendix J is required to demonstrate 
compliance with standards based on the new appendix J metrics.
Energy Efficiency Ratio and Water Efficiency Ratio
    Appendix J defines new metrics for representing clothes washer 
efficiency: energy efficiency ratio (``EER'') \8\ and water efficiency 
ratio (``WER'').\9\
---------------------------------------------------------------------------

    \8\ EER is defined as the weighted-average load size in pounds 
(``lbs'') divided by the sum of (1) the per-cycle machine energy, 
(2) the per-cycle water heating energy, (3) the per-cycle drying 
energy, and (4) the per-cycle standby and off mode energy 
consumption, in kilowatt-hours (``kWh'').
    \9\ WER is defined as the weighted-average load size in lbs 
divided by the total weighted per-cycle water consumption for all 
wash cycles in gallons (``gal'').
---------------------------------------------------------------------------

    DOE proposes to require including EER and WER as public information 
in a certification report for RCWs tested in accordance with appendix 
J.
    In the June 2022 RCW Final Rule, DOE established rounding 
requirements for EER and WER in 10 CFR 430.23(j)(2)(ii) and (j)(4)(ii), 
respectively. 87 FR 33316, 33381. These requirements specify rounding 
EER to the nearest 0.01 lb/kWh/cycle and rounding WER to the nearest 
0.01 gal/kWh/cycle. DOE proposes to specify these same rounding 
requirements for EER and WER at 10 CFR 430.29(c).
    DOE requests comment on the proposed RCW reporting requirements for 
EER and WER, including the proposed rounding requirements.
Type of Control System
    The existing RCW product classes are applicable to automatic 
clothes washers.\10\ Whereas performance-based standards are currently 
applicable for all classes of automatic RCWs, DOE has not established 
performance-based standards for semi-automatic RCWs. On March 3, 2023, 
DOE published an energy conservation standards NOPR that includes a 
proposal to re-establish a separate product class and separate 
performance-based energy conservation standards for semi-automatic 
RCWs.\11\ 88 FR 13520. To distinguish basic models as either automatic 
or semi-automatic for the purpose of determining whether the current 
performance-based standards apply, as well as which energy conservation 
standards would apply if DOE were to finalize its proposal to establish 
performance-based energy conservation standards for semi-automatic 
RCWs, DOE proposes to require reporting the type of control system 
(automatic or semi-automatic) as public information to be included in a 
certification report for RCWs tested in accordance with appendix J.
---------------------------------------------------------------------------

    \10\ DOE defines ``automatic clothes washer'' as a class of 
clothes washer that has a control system that is capable of 
scheduling a preselected combination of operations, such as 
regulation of water temperature, regulation of the water fill level, 
and performance of wash, rinse, drain, and spin functions without 
the need for user intervention subsequent to the initiation of 
machine operation. Some models may require user intervention to 
initiate these different segments of the cycle after the machine has 
begun operation, but they do not require the user to intervene to 
regulate the water temperature by adjusting the external water 
faucet valves. 10 CFR 430.2.
    \11\ DOE defines ``semi-automatic clothes washer'' as a class of 
clothes washer that is the same as an automatic clothes washer 
except that user intervention is required to regulate the water 
temperature by adjusting the external water faucet valves. 10 CFR 
430.2.
---------------------------------------------------------------------------

    DOE requests comment on its proposal to require reporting the type 
of control system (automatic or semi-automatic) for RCWs.
Other Requirements
    For RCWs tested in accordance with appendix J, DOE also proposes to 
establish public reporting requirements for RMC, clothes container 
capacity, and type of loading (top-loading or front-loading), 
consistent with the current reporting requirements specified at 10 CFR 
429.20(b)(2)(ii) for RCWs tested in accordance with appendix J2. DOE 
notes that the current requirement at 10 CFR 429.20(b)(3) to report a 
list of all cycle selections comprising the complete energy test cycle 
for each basic model applies to all RCWs and would therefore also apply 
to any RCW tested in accordance with appendix J. Similarly, the 
proposed requirement to report test cloth lot number would also apply 
to RCWs tested in accordance with appendix J. These reporting 
requirements would be required only at such time as use of appendix J 
is required to demonstrate compliance with standards based on the new 
appendix J metrics.
    DOE requests comment on its proposal to require reporting of RMC, 
clothes container capacity, and type of loading (top-loading or front-
loading) for RCWs tested in accordance with appendix J.
2. Reporting Costs and Impacts
    In this NOPR, DOE proposes to align RCW certification reporting 
requirements with the energy conservation requirements that would be 
applicable to RCWs tested in accordance with appendix J.
    Currently, manufacturers report IMEF, IWF, capacity, RMC, loading 
type, and cycle selections. Manufacturers would additionally report 
test cloth lot number if the proposed amendments were adopted. For RCWs 
manufactured after the compliance date of any future energy 
conservation standards based on use of appendix J, manufacturers would 
be required to report EER, WER, capacity, RMC, control system type, 
loading type, cycle selections, and test cloth lot number, if the 
proposed amendments are adopted.
    DOE has tentatively determined that these proposed amendments would 
not impose additional costs for manufacturers because manufacturers of 
RCWs are already submitting certification reports to DOE and should 
have readily available the information that DOE is proposing to collect 
as part of this rulemaking. DOE does not believe the revised reporting 
requirements will cause any appreciable change in reporting burden or 
hours as

[[Page 67470]]

compared to what RCW manufacturers are currently doing today as the 
proposed amendments are replacement metrics or information that should 
be readily available.
    DOE requests comment on the certification reporting costs of the 
amendments proposed for RCWs.

D. Pool Heaters

    DOE is proposing to amend the reporting requirements for consumer 
pool heaters. DOE defines pool heaters as an appliance designed for 
heating non-potable water contained at atmospheric pressure, including 
heating water in swimming pools, spas, hot tubs, and similar 
applications. 10 CFR 430.2. In the final rule published on May 30, 2023 
(``May 2023 Pool Heaters Final Rule''), DOE amended the energy 
conservation standards for consumer pool heaters. 88 FR 34624. While 
the current standards only apply to gas-fired pool heaters, the new and 
amended standards apply to both gas-fired pool heaters and electric 
pool heaters (excluding electric spa heaters) \12\ and use an updated 
efficiency metric. Id. at 88 FR 34704. Consistent with the May 2023 
Pool Heaters Final Rule, DOE is proposing amendments to the reporting 
requirements for consumer pool heaters.
---------------------------------------------------------------------------

    \12\ ``Electric pool heater'' means a pool heater other than an 
electric spa heater that uses electricity as its primary energy 
source. An ``electric spa heater'' means a pool heater that (1) uses 
electricity as its primary energy source; (2) has an output capacity 
of 11 kW or less; and (3) is designed to be installed within a 
portable electric spa. 88 FR 34624, 34703. DOE did not establish 
standards for electric spa heaters in the May 2023 Pool Heaters 
Final Rule, so the certification requirements proposed in this NOPR 
pertain only to electric pool heaters.
---------------------------------------------------------------------------

1. Reporting
    Under the existing requirements in 10 CFR 429.24, manufacturers of 
gas-fired pool heaters must report: thermal efficiency in percent and 
input capacity in Btu/h. 10 CFR 429.24(b)(1)-(2). These requirements 
provide for certifying compliance with the April 16, 2013 thermal 
efficiency standards. The amended standards are based on a different 
metric: integrated thermal efficiency. (See 88 FR 34624, 34625). DOE is 
proposing to update these certification requirements and align them 
with the energy conservation standards outlined in the May 2023 Pool 
Heaters Final Rule. DOE is additionally proposing general certification 
requirements for consumer pool heaters. DOE discusses these proposed 
updates in the following paragraphs.
    The current standards for consumer pool heaters at 10 CFR 430.32(k) 
provide only minimum thermal efficiency (``TE'') requirements for gas-
fired pool heaters, which does not include standby mode and off mode 
energy consumption. While the TE metric has historically been used to 
rate pool heaters, the current test procedure at appendix P to subpart 
B of 10 CFR part 430 (``appendix P'') includes provisions to determine 
the new integrated thermal efficiency (``TEI'') metric, 
which includes standby mode and off mode energy consumption as required 
by EPCA. Hence, the May 2023 Pool Heaters Final Rule established new 
and amended standards for gas-fired pool heaters and electric pool 
heaters in terms of TEI. (88 FR 34624, 34625) In the May 
2023 Pool Heaters Final Rule, DOE stated that it would consider 
requirements for reporting and certifying TEI in lieu of TE 
in a separate rulemaking. 88 FR 34624, 34636. DOE stated that it would 
also consider requirements for reporting and certifying active 
electrical power \13\ along with the representative value for 
TEI in a separate rulemaking. Id.
---------------------------------------------------------------------------

    \13\ ``Active electrical power'' means the maximum electrical 
power consumption in active mode for an electric pool heater.
---------------------------------------------------------------------------

    In the pool heaters energy conservation standards NOPR rulemaking 
(``April 2022 Pool Heaters NOPR''), DOE addressed comments from Air-
Conditioning, Heating, and Refrigeration Institute (``AHRI'') regarding 
the level of precision required for representations of TEI. 
87 FR 22640, 22652 (Apr. 15, 2022). AHRI suggested that, for products 
where the efficiency ratings are less than 100 percent, a change of one 
or two points may make a difference; however, for products such as heat 
pump pool heaters with efficiency ratings that can exceed 300 percent, 
a difference of one or two points is inconsequential. Id. DOE stated 
that it would consider rounding requirements for consumer pool heaters 
in a separate rulemaking addressing certification reports. Id.
    The April 2022 Pool Heaters NOPR sought comment on changes to 
certification and enforcement requirements. Id. DOE received comments 
from Rheem Manufacturing Company (``Rheem'') regarding certification 
provisions for consumer pool heaters. Rheem recommended that DOE update 
the certification provisions at 10 CFR 429.24 to require certification 
of TEI and either input capacity or active electrical power 
as necessary. (Rheem, Docket No. EERE-2021-BT-STD-0020, No. 19 at p. 2) 
Rheem also recommended that DOE evaluate adding certification 
provisions--similar to the requirements for consumer water heaters--
which allow for the propane gas version of a basic model to be rated 
using the natural gas version if the propane gas input rate is within 
10 percent of the natural gas input rate. (Rheem, Docket No. EERE-2021-
BT-STD-0020, No. 19 at p. 10)
    In response to Rheem's request to use representations of natural 
gas basic models for propane basic models, DOE notes that the water 
heater certification provisions referenced by the commenter are 
specifically for alternative efficiency determination methods (see 10 
CFR 429.70(g)(1)). At this time, manufacturers of consumer pool heaters 
are not authorized to use alternative efficiency determination methods 
for representations pertaining to consumer pool heaters (see 10 CFR 
429.70(a)), and the May 2023 Pool Heaters Final Rule did not establish 
this allowance. (88 FR 34624) Hence, DOE is not proposing special 
certification requirements for propane gas-fired pool heaters.
    For consumer pool heaters, DOE proposes to clarify provisions for 
certifying input capacity, establish provisions for certifying active 
electrical power, and establish certification requirements for 
TEI (including rounding requirements). DOE has tentatively 
determined that certification of input capacity and active electrical 
power is necessary because these values are used to determine the 
TEI standard that applies to a pool heater.
    DOE proposes to clarify that representations of input capacity for 
gas-fired pool heaters must be made based on the average of the input 
capacities measured for each tested unit of the basic model, and 
rounded to the nearest 1,000 Btu/h.
    There are currently no certification requirements for electric pool 
heaters. DOE is proposing to establish requirements for active 
electrical power similar to those for input capacity, because these two 
values are analogous to each other for electric pool heaters and gas-
fired pool heaters, respectively.
    The May 2023 Pool Heaters Final Rule will require compliance with 
standards using the TEI metric; hence, DOE is also proposing 
to require certification of this value. The represented value for 
TEI would be rounded to the nearest tenth of one percent for 
gas-fired pool heaters. However, in consideration of the comments from 
AHRI indicating that the level of precision does not need to be so 
stringent for electric pool heaters, DOE is proposing that the value 
for TEI would be rounded to the nearest 1 percent for 
electric pool heaters. Until compliance with new TEI 
standards is mandatory, manufacturers of gas-fired pool heaters must 
still ensure that these

[[Page 67471]]

products comply with the current TE standards at 10 CFR 430.32(k). 
Therefore, DOE is maintaining the requirement for certifying TE of gas-
fired pool heaters for products that must comply with TE standards. 
Reporting of TEI would become mandatory upon the compliance 
date of the energy conservation standards adopted in the May 2023 Pool 
Heaters Final Rule, May 30, 2028, at which time manufacturers would no 
longer be required to report TE.
    DOE seeks comment on its proposal to require the reporting of input 
capacity, active electrical power, and integrated thermal efficiency. 
DOE also seeks comment on the proposed rounding requirements.
2. Reporting Costs and Impacts
    In this NOPR, DOE proposes to align pool heater certification 
reporting requirements with the energy conservation requirements that 
would be applicable to pool heaters, as finalized in the May 2023 Pool 
Heaters Final Rule.
    For gas-fired pool heaters, manufacturers currently report TE as a 
percentage and input capacity in Btu/h. As a result of the amended 
standards, manufacturers of gas-fired pool heaters would be required to 
report TEI as a percentage in lieu of TE when certifying 
compliance with the revised standards. For electric pool heaters, 
manufacturers are not currently required to submit certification 
reports as there are no applicable standards at this time. As a result 
of the amended standards, manufacturers of electric pool heaters would 
be required to report TEI as a percentage and active 
electrical power in Btu/h. 88 FR 34624, 34704.
    DOE has tentatively determined that these proposed amendments would 
not impose additional costs for manufacturers of gas-fired pool heaters 
because manufacturers of gas-fired pool heaters are already submitting 
certification reports to DOE and should have the information that DOE 
is proposing to collect as part of this rulemaking readily available. 
DOE does not believe the revised reporting requirements will cause any 
appreciable increase in any manufacturer's reporting burden or hours 
compared to certifying under current gas-fired pool heater 
requirements. For electric pool heaters, manufacturers are not 
currently required to submit certification reports to DOE because 
electric pool heaters are not currently subject to any applicable 
energy conservation standards. Any manufacturer of electric pool 
heaters would be required to submit certification reports for electric 
pool heaters upon the compliance date of the amended energy 
conservation standards, May 30, 2028. 88 FR 34624, 34704. Costs 
associated with the proposed updates to reporting requirements are 
discussed in section IV.C of this document.
    DOE requests comment on the certification reporting costs of the 
amendments proposed for pool heaters.

E. Dehumidifiers

    DOE is proposing to amend the reporting requirements for 
dehumidifiers, which DOE defines as products--other than portable air 
conditioners, room air conditioners, or packaged terminal air 
conditioners--that are self-contained, electrically operated, and 
mechanically encased assemblies consisting of (1) a refrigerated 
surface (evaporator) that condenses moisture from the atmosphere; (2) a 
refrigerating system, including an electric motor; (3) an air-
circulating fan; and (4) a means for collecting or disposing of the 
condensate. 10 CFR 430.2. Use of appendix X1 to subpart B of 10 CFR 
part 430 is currently required for any representations of energy use or 
efficiency of portable and whole-home dehumidifiers, including 
demonstrating compliance with the currently applicable energy 
conservation standards. Consequently, appendix X to subpart B of 10 CFR 
part 430 is obsolete for dehumidifiers manufactured on or after June 
13, 2019. Therefore, DOE is proposing amendments to the remove the 
outdated appendix X reporting requirements, consistent with the 
proposed removal of appendix X in the test procedure NOPR published on 
June 9, 2022 (``June 2022 Dehumidifiers NOPR''). 87 FR 35286, 35305.
1. Reporting
    Under the existing requirements in 10 CFR 429.36, manufacturers 
must report: energy factor in liters per kilowatt hour (``liters/kWh'') 
and capacity in pints per day when certifying compliance with 
dehumidifiers tested in accordance with appendix X. 10 CFR 
429.36(b)(2)(i). However, use of appendix X is no longer permitted for 
compliance because use of appendix X1 to subpart B of part 430 
(``appendix X1'') is required to demonstrate compliance with standards 
for products manufactured on or after June 13, 2019, and the June 2022 
Dehumidifiers NOPR proposed the removal of appendix X. 87 FR 35286, 
35305. DOE is proposing to remove the outdated appendix X certification 
requirements consistent with the proposed removal of appendix X in the 
June 2022 Dehumidifiers NOPR.
    DOE seeks comment on its proposal to remove the outdated appendix X 
certification requirements.
2. Reporting Costs and Impacts
    In this NOPR, DOE proposes to align dehumidifier certification 
reporting requirements with the appendix X1 test procedure 
requirements, use of which was required beginning on June 13, 2019, by 
removing the appendix X requirements applicable to dehumidifiers 
manufactured prior to June 13, 2019.
    DOE has tentatively determined that these proposed amendments would 
not impose additional costs for manufacturers because the only proposed 
amendments are the removal of outdated requirements. DOE is not 
proposing any amendments to the reporting requirements associated with 
appendix X1 and is proposing to remove certification requirements 
associated with a prior appendix. Therefore, DOE does not believe the 
revised reporting requirements will cause any appreciable change in 
reporting burden or hours compared to certifying under current 
dehumidifier requirements.
    DOE requests comment on the certification reporting costs of the 
amendments proposed for dehumidifiers.

F. External Power Supplies

    DOE is proposing to amend the reporting requirements for EPSs. DOE 
defines an EPS as an external power supply circuit that is used to 
convert household electric current into direct current or lower-voltage 
AC current to operate a consumer product. 10 CFR 430.2. In the test 
procedure final rule published on August 19, 2022, DOE amended the 
appendix Z test procedure for EPSs. 87 FR 51200. Consistent with that 
final rule, DOE is proposing amendments to the reporting requirements.
1. Reporting
    Under the existing requirements in 10 CFR 429.37(b)(2), 
manufacturers must report the following based on the external power 
supply type:
    For external power supplies, manufacturers currently report the 
average active mode efficiency as a percentage, no-load mode power 
consumption in watts, nameplate output power in watts, and, if missing 
from the nameplate, the output current in amperes of the basic model or 
the output current in amperes of the highest- and lowest-voltage models 
within the external power supply design family.

[[Page 67472]]

    For switch-selectable single-voltage external power supplies, 
manufacturers currently report the average active mode efficiency as a 
percentage, no-load mode power consumption in watts using the lowest 
and highest selectable output voltages, nameplate output power in 
watts, and, if missing from the nameplate, the output current in 
amperes.
    For adaptive single-voltage external power supplies, manufacturers 
currently report the average active-mode efficiency as a percentage at 
the highest and lowest nameplate output voltages, no-load mode power 
consumption in watts, nameplate output power in watts at the lowest and 
highest nameplate output voltages, and, if missing from the nameplate, 
the output current in amperes at the lowest and highest nameplate 
output voltages.
    For external power supplies that are exempt from no-load mode 
requirements, manufacturers currently report a statement that the 
product is designed to be connected to a security or life safety alarm 
or surveillance system component, the average active-mode efficiency as 
a percentage, the nameplate output power in watts, and if missing from 
the nameplate, the certification report must also include the output 
current in amperes of the basic model or the output current in amperes 
of the lowest- and highest-voltage models within the external power 
supply design family. Manufacturers of these exempt external power 
supplies are additionally required to report, if the aggregate total 
number of exempt EPSs sold as spare and service parts exceeds 1,000 
units across all models: the importer or domestic manufacturer's name 
and address, the brand name, and the number of units sold during the 
most recent 12-calendar-month period ending on July 31. 10 CFR 
429.37(b)(3) and 10 CFR 429.37(c).
    These requirements provide for certifying compliance with the 
energy conservation standards applicable to EPSs manufactured on or 
after February 10, 2014. DOE is proposing to align the reporting 
requirements with the amended appendix Z test procedure, use of which 
was required beginning September 19, 2022, and proposing general 
certification requirements for EPSs. DOE discusses these proposed 
updates in the sections as follows.
a. Output Cord Specifications
    DOE's amended EPS test procedure requires that EPSs be tested with 
the output cord they are shipped with. For EPSs not shipped with an 
output cord, the EPS must be tested with a manufacturer's recommended 
output cord. For EPSs not shipped with an output cord and for which the 
manufacturer does not recommend an output cord, the amendments specify 
that the EPS must be tested with a 3-foot-long output cord with a 
conductor thickness that is minimally sufficient to carry the maximum 
required current. See section 4(g) of appendix Z to subpart B of 10 CFR 
part 430.
    To better align the reporting requirements with the test procedure, 
DOE is proposing to add a reporting requirement of the included output 
cord specifications (gauge and length); for EPSs not shipped with an 
output cord, the specifications (gauge and length) for the 
manufacturer's recommended output cord would be provided. For EPSs not 
shipped with an output cord and for which the manufacturer does not 
recommend an output cord, the gauge of the 3-foot-long output cord will 
be provided.
    DOE seeks comment on its proposal to require the reporting of 
output cord specifications for EPSs.
b. Output Voltage
    In DOE's current EPS test procedure and energy conservation 
standards, determining factors for EPS type and product class are the 
nature of the output voltage and its measured value. Output voltage 
type--(i.e. AC, DC, multiple voltage and/or adaptive) determines the 
applicable portion of the test procedure and the template that must be 
used for certification purposes. The measured value of the voltage 
determines whether the EPS falls within the basic or low voltage 
product class. To better align the reporting requirements with the test 
procedure and energy conservation standards for EPSs, DOE is proposing 
to add a reporting requirement for the measured output voltage for each 
port.
    DOE seeks comment on its proposal to require the reporting of 
measured output voltage for EPSs for each port.
c. Additional Date Reporting Requirements for Exempt EPSs
    To further clarify the time period during which the exempt EPSs 
were sold, DOE is proposing to further require the manufacturer to 
report the applicable timeframe of which the number of exempt EPSs were 
sold.
    DOE seeks comment on its proposal to require manufacturers of 
exempt EPSs to report the year for which the sales number being 
reported represents.
2. Reporting Costs and Impacts
    In this NOPR, DOE proposes to align EPS certification reporting 
requirements with the revised appendix Z test procedure requirements, 
use of which was required beginning September 19, 2022.
    For switch-selectable single-voltage external power supplies, 
manufacturers currently report the average active mode efficiency as a 
percentage, no-load mode power consumption in watts using the lowest 
and highest selectable output voltages, nameplate output power in 
watts, and, if missing from the nameplate, the output current in 
amperes, and would additionally report included or recommended output 
cord specifications and the measured output voltage at the lowest and 
highest selectable output voltages if the proposed amendments are 
adopted.
    For adaptive single-voltage external power supplies, manufacturers 
currently report the average active-mode efficiency as a percentage at 
the highest and lowest nameplate output voltages, no-load mode power 
consumption in watts, nameplate output power in watts at the lowest and 
highest nameplate output voltages, and, if missing from the nameplate, 
the output current in amperes at the lowest and highest nameplate 
output voltages, and would additionally report included or recommended 
output cord specifications and the measured output voltage at the 
lowest and highest nameplate output voltages if the proposed amendments 
are adopted.
    For external power supplies that are exempt from no-load mode 
requirements, manufacturers currently report a statement that the 
product is designed to be connected to a security or life safety alarm 
or surveillance system component, the average active-mode efficiency as 
a percentage, the nameplate output power in watts, and if missing from 
the nameplate, the certification report must also include the output 
current in amperes of the basic model or the output current in amperes 
of the lowest- and highest-voltage models within the external power 
supply design family, and would additionally report included or 
recommended output cord specifications and the measured output voltage 
or the measured output voltage of the lowest and highest voltage models 
within the external power supply design family, and the timeframe of 
which these exempt EPSs were sold, if the proposed amendments are 
adopted.
    For all other external power supplies, manufacturers currently 
report the average active mode efficiency as a percentage, no-load mode 
power consumption in watts, nameplate output power in watts, and, if 
missing from the nameplate, the output current in

[[Page 67473]]

amperes of the basic model or the output current in amperes of the 
highest- and lowest-voltage models within the external power supply 
design family, and would additionally report included or recommended 
output cord specifications and the measured output voltage or the 
measured output voltage of the lower and highest voltage models within 
the external power supply design family if the proposed amendments are 
adopted.
    DOE has tentatively determined that these proposed amendments would 
not impose additional costs for manufacturers because manufacturers of 
EPSs are already submitting certification reports to DOE and should 
have readily available the information that DOE is proposing to collect 
as part of this rulemaking. DOE does not believe the revised reporting 
requirements will cause any appreciable change in reporting burden or 
hours as compared to what EPS manufacturers are currently doing today.
    DOE requests comment on the certification reporting costs of the 
amendments proposed for EPSs.

G. Battery Chargers

    DOE is proposing to amend the reporting requirements for battery 
chargers, which DOE defines as devices that charge batteries for 
consumer products, including battery chargers embedded in other 
consumer products. 10 CFR 430.2. In the test procedure final rule 
published on September 8, 2022 (``September 2022 Battery Charger Final 
Rule''), DOE amended the scope of coverage and test procedure 
provisions for battery chargers. 87 FR 55090. On March 15, 2023, DOE 
published an energy conservation standards NOPR for battery chargers 
that was developed based on the amended test procedure. 88 FR 16112. 
Consistent with the test procedure final rule and the energy 
conservation standards NOPR, DOE is proposing to reorganize current 
reporting requirements and add new reporting requirements that would 
become mandatory upon the compliance date of any future amended energy 
conservation standards for battery chargers.
1. Reporting
    Under the existing requirements in 10 CFR 429.39, manufacturers 
must report: (1) the nameplate battery voltage of the test battery in 
volts, the nameplate battery charge capacity of the test battery in 
ampere-hours, and the nameplate battery energy capacity of the test 
battery in watt-hours; and (2) the represented values for the 
maintenance mode power (Pm), standby mode power 
(Psb), off mode power (Poff), battery discharge 
energy (Ebatt), 24-hour energy consumption (E24), 
duration of the charge and maintenance mode test (tcd), and 
unit energy consumption (UEC); and (3) the manufacturer and model of 
the test battery, and the manufacturer and model, when applicable, of 
the external power supply. 10 CFR 429.39. These requirements provide 
for certifying compliance with the energy conservation standards 
applicable to battery chargers manufactured on or after June 13, 2018. 
DOE is proposing to reorganize these requirements and align the 
reporting requirements with the amended test procedure at appendix Y to 
subpart B of part 430 (``appendix Y''), use of which was required 
beginning on March 7, 2023. DOE is also proposing new reporting 
requirements to the certification requirements for battery chargers 
tested under appendix Y1 to subpart B of part 430 (``appendix Y1''), 
use of which would be required upon the compliance date of any future 
amended energy conservation standards for battery chargers. DOE 
discusses these proposed appendix Y1 updates in the sections as 
follows.
a. Reporting Requirements for Battery Chargers Tested Under Appendix Y1
    In the September 2022 Battery Charger Final Rule, DOE established a 
new appendix Y1 for the multi-metric testing approach for battery 
chargers. Under the new multi-metric testing approach, instead of 
computing and reporting the UEC value, which captures the performance 
of a battery charger in all modes of operation into a single metric, 
manufacturers are required to calculate and report the battery charger 
energy and power values for each mode of operation separately. These 
modes consist of active charge mode, standby mode, and off mode. 87 FR 
55090, 55100-55105.
    DOE is proposing to update the battery charger reporting 
requirements in 10 CFR 429.39 to align with the new multi-metric test 
procedure by (1) removing the UEC reporting requirement for both wired 
and fixed-location wireless battery chargers tested under appendix Y1, 
and (2) adding reporting requirements for active charge energy 
Ea and no-battery mode power Pnb. Additionally, 
DOE is proposing to include active charge energy Ea (as 
measured in accordance with appendix Y1) as an optional reporting 
requirement when certifying compliance with the existing appendix Y 
requirements to assist DOE in gathering data for any future amended 
energy conservation standards. Whether manufacturers choose to report 
this proposed optional information would have no impact on the validity 
of representations made when certifying compliance with appendix Y or 
the current energy conservation standards.
    DOE seeks comment on the proposed updates to reporting requirements 
for wired and fixed-location wireless battery chargers tested under 
appendix Y1.
b. Reporting Requirements for Open-Placement Wireless Battery Chargers 
Tested Under Appendix Y1
    In the September 2022 Battery Charger Final Rule, DOE also expanded 
the battery charger testing scope to include testing of fixed-location 
wireless chargers in all modes of operation and testing of open-
placement wireless chargers in no-battery mode only. 87 FR 55090, 
55095-55098.
    Under the current appendix Y test procedure, all modes of operation 
would need to be tested for battery chargers covered under the test 
procedure scope. As such, there was no need to differentiate the 
reporting requirements for wired vs. wireless chargers. However, under 
appendix Y1, open-placement wireless chargers will only need to be 
tested in the no-battery mode of operation. Accordingly, DOE is 
proposing to further specify that for open-placement wireless chargers, 
only the no-battery mode power, Pnb, would need to be 
reported.
    DOE seeks comment on the proposal to further specify the reporting 
requirements for open-placement wireless battery chargers tested under 
appendix Y1.
2. Reporting Costs and Impacts
    In this NOPR, DOE proposes to align battery charger certification 
reporting requirements with the amended appendix Y test procedural 
requirements, use of which was required beginning on October 11, 2022, 
and the newly established appendix Y1 test procedure, use of which 
would be required at such time as compliance is required with any 
amended energy conservation standards based on these new metrics as 
measured using appendix Y1.
    For wired chargers tested under current appendix Y, manufacturers 
currently report (1) the nameplate battery voltage of the test battery 
in volts, the nameplate battery charge capacity of the test battery in 
ampere-hours, and the nameplate battery energy capacity of the test 
battery in watt-hours; and (2) the represented values for the 
Pm, Psb, Poff, Ebatt, 
E24, tcd, and UEC; and (3) the manufacturer and 
model of the test battery, and the manufacturer

[[Page 67474]]

and model, when applicable, of the external power supply. If the 
proposed amendments are adopted, when tested under appendix Y1, instead 
of reporting UEC and E24 values, manufacturers would report 
the active charge energy (Ea). Manufacturers would 
additionally report no-battery mode power, Pnb.
    For fixed-location wireless chargers tested under appendix Y1, 
manufacturers would need to report (1) the nameplate battery voltage of 
the test battery in volts, the nameplate battery charge capacity of the 
test battery in ampere-hours, and the nameplate battery energy capacity 
of the test battery in watt-hours; and (2) the represented values for 
the Pm, Pnb, Psb, Poff, 
Ebatt, Ea, and duration of the charge and 
tcd; and (3) the manufacturer and model of the test battery, 
and the manufacturer and model--when applicable--of the external power 
supply, if the proposed amendments are adopted.
    For open-placement wireless chargers tested under appendix Y1, 
manufacturers would need to report the represented values for 
Pnb, and the manufacturer and model, when applicable, of the 
external power supply, if the proposed amendments are adopted.
    DOE has tentatively determined that these proposed amendments would 
not impose additional costs for manufacturers because manufacturers of 
battery chargers are already submitting certification reports to DOE 
and the additional information that DOE is proposing to collect as part 
of this rulemaking should be readily available to manufacturers and 
would not require additional testing. DOE does not believe the revised 
reporting requirements will cause any appreciable change in reporting 
burden or hours as compared to what battery charger manufacturers are 
currently doing today.
    DOE requests comment on the certification reporting costs of the 
amendments proposed for battery chargers.

H. Computer Room Air Conditioners

    DOE is proposing to amend the reporting requirements for CRACs. DOE 
defines ``computer room air conditioner'' as a basic model of 
commercial package air-conditioning and heating equipment (packaged or 
split) that is: used in computer rooms, data processing rooms, or other 
information technology cooling applications; rated for sensible 
coefficient of performance (SCOP) and tested in accordance with 10 CFR 
431.96; and is not a covered consumer product under 42 U.S.C. 6291(1)-
(2) and 42 U.S.C. 6292. A CRAC may be provided with, or have as 
available options, an integrated humidifier, temperature and/or 
humidity control of the supplied air, and reheating function. 10 CFR 
431.92. In the energy conservation standards final rule published in 
the Federal Register on June 2, 2023 (June 2023 CRACs final rule), DOE 
amended the energy conservation standards for CRACs and adopted the net 
sensible coefficient of performance (NSenCOP) metric. 88 FR 36392. 
Consistent with the June 2023 CRACs final rule, DOE is proposing 
amendments to the reporting requirements for CRACs.
1. Reporting
    Under the existing reporting requirements for CRACs in 10 CFR 
429.43(b)(2)(ix), manufacturers must report: net sensible cooling 
capacity in Btu/h, net cooling capacity in Btu/h, configuration 
(upflow/downflow), economizer presence (or lack thereof), condenser 
medium (air, water, or glycol-cooled), SCOP, and rated airflow in 
standard cubic feet per minute (SCFM). These requirements provide for 
certifying compliance with the standards applicable to CRACs 
manufactured on or after October 29, 2012, for units of capacity less 
than 65,000 Btu/hr. and October 29, 2013, for the remainder of covered 
CRACs. DOE is proposing to update these requirements and align the 
reporting requirements with the energy conservation standards in the 
June 2023 CRACs final rule. DOE is also proposing other general 
certification requirements for CRACs to better ascertain applicable 
standards and represented values, including whether the basic model is 
split system or single-package, unit configuration, and refrigerant 
utilized. DOE discusses these proposed updates in the sections as 
follows.
a. Revising Certification Reporting Requirements at 10 CFR 
429.43(b)(2)(ix) When Certifying With NSenCOP Standards
    Manufacturers are currently required to certify compliance with 
SCOP standards, in addition to the other equipment-specific reporting 
requirements. In this NOPR, DOE is proposing to amend the certification 
requirements to allow certifying compliance with NSenCOP standards and 
related equipment-specific reporting requirements. Specifically, DOE 
proposes to place the existing reporting requirements for SCOP 
standards in new 10 CFR 429.43(b)(2)(ix)(A), and to place the new 
reporting requirements for NSenCOP standards in new 10 CFR 
429.43(b)(2)(ix)(B). The NSenCOP standard reporting requirements 
include the net sensible cooling capacity in Btu/h, the net total 
cooling capacity in Btu/h, whether the basic model is split system or 
single-package, the configuration (e.g., downflow, upflow ducted, 
upflow non-ducted, horizontal flow, ceiling-mounted ducted, ceiling-
mounted non-ducted), fluid economizer presence (or lack thereof), 
condenser heat rejection medium (air, water, or glycol-cooled), 
NSenCOP, rated airflow in SCFM, and the refrigerant used to determine 
the represented values at 10 CFR 429.43(b)(2)(ix).
    DOE seeks comment on its proposal to require the reporting of net 
sensible cooling capacity in Btu/h, the net total cooling capacity in 
Btu/h, whether the basic model is split system or single-package, the 
configuration (e.g., downflow, upflow ducted, upflow non-ducted, 
horizontal flow, ceiling-mounted ducted, ceiling-mounted non-ducted), 
fluid economizer presence (or lack thereof), condenser heat rejection 
medium (air, water, or glycol-cooled), NSenCOP, rated airflow in SCFM, 
and the refrigerant used to determine the represented values.
b. Adding Supplemental Testing Instructions for CRACs at 10 CFR 
429.43(b)(4)(viii)
    Currently, manufacturers must submit supplemental information 
regarding additional testing instructions, if applicable, and specify 
which special features, if any, were included in rating the basic 
model. 10 CRF 429.43(b)(4)(viii). The supplemental information 
submitted in PDF format allows for third-party testing of equipment. 
For CRACs, there are currently no specific requirements for the 
supplemental PDF. For SCOP certification, DOE proposes to maintain the 
current requirements of 10 CFR 429.43(b)(4)(viii), but move them to 10 
CFR 429.43(b)(4)(viii)(A). For NSenCOP certification, DOE proposes to 
specify the information required in supplemental testing instructions 
that would enable independent testing of the relevant equipment and to 
align with the corresponding requirements for CUACs, where appropriate. 
This includes, but is not limited to supplementary information about 
compressor break-in period duration, control set points, optional 
motor/drive kits and associated settings, and any other additional 
testing instructions. DOE proposes to add these new provisions when 
certifying to NSenCOP in 10 CFR 429.43(b)(4)(viii)(B).

[[Page 67475]]

    The proposed certification requirements provide further direction 
to the existing requirements and would not result in significant 
additional burden for manufacturers. Where DOE identifies specific 
test-related information, the relevant information is already collected 
by or available to the manufacturer, and as such, reporting that 
information to DOE would result in minimal additional burden.
    DOE seeks comment on its proposed supplemental testing instructions 
requirements for CRACs when certifying compliance with NSenCOP 
standards.
c. Certification of Model Numbers for Split Systems
    DOE's current certification reporting requirements for CRACs at 10 
CFR 429.43(b)(2)(ix) do not specify the model numbers that the 
manufacturer must certify. Specifically, for split systems, the current 
regulations do not explicitly require certification of both the outdoor 
and indoor unit model numbers. Therefore, DOE is proposing at 10 CFR 
429.43(b)(6) to clarify that the manufacturer must certify individual 
model numbers for both the indoor unit and the outdoor unit.
    DOE seeks comment on its proposal to require the reporting of both 
indoor unit and outdoor unit individual model numbers for split-system 
CRACs.
d. AEDM Tolerance for NSenCOP
    DOE's existing testing regulations allow the use of an alternative 
efficiency determination method (AEDM), in lieu of testing, to simulate 
the efficiency of CRACs. 10 CFR 429.43(a). For models certified with an 
AEDM, results from DOE verification tests are subject to certain 
tolerances when compared to certified ratings. Currently, DOE specifies 
a 5-percent tolerance for CRAC verification tests for SCOP, identical 
to the current tolerance specified for single-point metrics (i.e., EER 
and COP) for other categories of commercial air conditioners and heat 
pumps. See table 2 to paragraph (c)(5)(vi)(B) at 10 CFR 429.70. In 
alignment with the tolerance specified for SCOP, DOE is proposing to 
specify a tolerance of 5 percent for CRAC verification tests for 
NSenCOP.
    DOE seeks comment on its proposal to specify a tolerance of 5 
percent for CRAC verification tests for NSenCOP.
2. Reporting Costs and Impacts
    In this NOPR, DOE proposes to align CRAC certification reporting 
requirements with the amended energy conservation standards in the June 
2023 CRACs Final Rule.
    DOE has tentatively determined that these proposed amendments would 
not impose additional costs for manufacturers because manufacturers of 
CRACs are already submitting certification reports to DOE and should 
have readily available the information that DOE is proposing to collect 
as part of this rulemaking. DOE does not believe the revised reporting 
requirements will cause any appreciable change in reporting burden or 
hours as compared to what CRACs manufacturers are currently doing.
    DOE requests comment on the certification reporting costs of the 
amendments proposed for CRACs.

I. Direct Expansion-Dedicated Outdoor Air Systems

    DOE is proposing to establish reporting requirements for DX-DOASes. 
DOE defines ``direct expansion-dedicated outdoor air system'' as a 
basic model of commercial package air-conditioning and heating 
equipment (packaged or split) that is a unitary dedicated outdoor air 
system \14\ that is capable of dehumidifying air to a 55 [deg]F dew 
point--when operating under Standard Rating Condition A as specified in 
Table 4 or Table 5 of AHRI (I-P)-2020, ``Performance Rating of DX-
Dedicated Outdoor Air System Units'' (``AHRI 920-2020'') with a 
barometric pressure of 29.92 in Hg--for any part of the range of 
airflow rates advertised in manufacturer materials, and has a moisture 
removal capacity of less than 324 pounds per hour (``lb/h''). 10 CFR 
431.92. In the DX-DOAS energy conservation standards final rule 
published on November 1, 2022 (``November 2022 DX-DOAS Final Rule''), 
DOE adopted energy conservation standards for DX-DOASes. 87 FR 65651. 
Consistent with that final rule, DOE is proposing to establish 
reporting requirements for DX-DOASes.
---------------------------------------------------------------------------

    \14\ DOE defines ``unitary dedicated outdoor air system'' as a 
category of small, large, or very large commercial package air-
conditioning and heating equipment that is capable of providing 
ventilation and conditioning of 100-percent outdoor air and is 
marketed in materials (including but not limited to, specification 
sheets, insert sheets, and online materials) as having such 
capability.
---------------------------------------------------------------------------

1. Reporting
    Prior to the adoption of energy conservation standards in the 
November 2022 DX-DOAS Final Rule, there were no energy conservation 
standards for DX-DOASes in 10 CFR 431.97, nor were there reporting 
requirements for this equipment in 10 CFR 429.43.\15\ Because DOE has 
now adopted energy conservation standards for DX-DOASes, DOE is 
proposing to establish reporting requirements in alignment with the 
standards adopted in the November 2022 DX-DOAS Final Rule. DOE 
discusses these proposals in the following sections.
---------------------------------------------------------------------------

    \15\ In the November 2022 DX-DOAS Final Rule, DOE adopted a 
requirement in 10 CFR 429.43(a)(3)(i) that the represented value of 
moisture removal capacity (``MRC'') be either between 95 and 100 
percent of the mean of the measured capacities of the units in the 
selected sample rounded to the nearest lb/hr multiple according to 
Table 3 of AHRI 920-2020 or the MRC output simulated by an AEDM 
rounded to the nearest lb/hr multiple according to Table 3 of AHRI 
920-2020. DOE is adopting these provisions. 87 FR 65658, 65667.
---------------------------------------------------------------------------

a. Addition of Certification Requirements To Include the New Metrics, 
ISMRE2 and ISCOP2
    In this NOPR, DOE is proposing certification requirements for 
certifying compliance with the new energy conservation standards for 
DX-DOAS, expressed in integrated seasonal moisture removal efficiency 2 
(``ISMRE2'') and integrated seasonal coefficient of performance 2 
(``ISCOP2''), as adopted in the November 2022 DX-DOAS Final Rule. 
Specifically, DOE proposes to add new 10 CFR 429.43(b)(2)(xi)(A) and 
require the following when certifying compliance with an ISMRE2 
standard: the ISMRE2 in lb/kWh, the rated moisture removal capacity at 
Standard Rating Condition A according to AHRI 920-2020 (incorporated by 
reference; see 10 CFR 429.4) (MRC in lb/h), and the rated supply 
airflow rate for 100 percent outdoor air applications (QSA 
in standard cubic feet per minute). The moisture removal capacity is 
used for certifying compliance and the rated supply airflow rate must 
be specified to determine how to test a basic model according to the 
DOE test procedure at appendix B to subpart F of 10 CFR part 431.
    Additionally, DOE proposes to require the following at 10 CFR 
429.43(b)(2)(xi)(B) when certifying compliance with an ISCOP2 standard 
in addition to an ISMRE2 standard \16\: the ISCOP2 in watts of heating 
per watts of power input (``W/W'').
---------------------------------------------------------------------------

    \16\ Certification and compliance with both the applicable 
ISCOP2 and ISMRE2 standards is required for the air-source heat pump 
and water-source heat pump DX-DOAS equipment classes.
---------------------------------------------------------------------------

    DOE proposes to include these certification provisions for DX-
DOASes in 10 CFR 429.43(b), consistent with other commercial HVAC 
equipment. As a result, the general requirements applicable to 
certification reports outlined in 10 CFR 429.12 would apply to DX-
DOASes, as currently outlined in the existing reporting requirements 
for commercial HVAC equipment. 10 CFR 429.43(b)(1).

[[Page 67476]]

    DOE seeks comment on requiring the reporting of ISMRE2 and ISCOP2 
to certify compliance with the standards applicable to DX-DOASes 
manufactured on or after May 1, 2024. DOE also seeks comment on 
reporting rated moisture removal capacity and rated supply airflow 
rate.
b. Reporting Requirements for DX-DOASes With Ventilation Energy 
Recovery Systems
    In the November 2022 DX-DOAS Final Rule, DOE adopted product-
specific enforcement provisions for DX-DOASes in 10 CFR 429.134(s) in 
addition to the revised energy conservation standards. These 
enforcement provisions specify how DOE would determine the ISMRE2 and 
ISCOP2 values when conducting enforcement testing for DX-DOASes with 
Ventilation Energy Recovery Systems (``VERS''). As outlined in Sec.  
429.134(s)(2)-(3), these provisions rely on values of VERS performance 
certified to DOE as the basis for determining the ISMRE2 and/or ISCOP2 
of the basic model being tested in some scenarios.
    To inform DOE's enforcement testing, DOE is proposing additional 
non-public certification reporting requirements for DX-DOASes with VERS 
in new subparagraph 10 CFR 429.43(b)(3)(iii). These reporting 
requirements include the method of determination of the exhaust air 
transfer ratio (``EATR''), sensible effectiveness, latent effectiveness 
of the ventilation energy recovery system (name and version of 
certified performance modeling software or if the device was directly 
tested), the test method (i.e., Option 1 or Option 2) for units rated 
based on testing, and motor control settings (including rotational 
speed) for energy recovery wheels--all of which would be used by DOE to 
determine ISMRE2 and/or ISCOP2 for enforcement testing and would be 
considered non-public information if adopted.
    DOE seeks comment on its proposal to include reporting requirements 
for DX-DOASes with ventilation energy recovery systems.
c. Supplemental Testing Instructions
    Currently, manufacturers of other covered commercial HVAC equipment 
types must submit in PDF format supplemental information regarding 
additional testing instructions, if applicable, and they must also 
specify which, if any, special features were included in rating the 
basic model. 10 CFR 429.43(b)(4). The supplemental information 
submitted in PDF format allows for third-party testing of equipment. 
Consistent with other commercial HVAC equipment types, DOE proposes to 
specify information required in supplemental testing instructions 
submitted in PDF format for DX-DOASes to enable independent testing of 
the relevant equipment and to align with the corresponding requirements 
for CUACs, where appropriate.
    Specifically, for all DX-DOASes, DOE is proposing the following 
content requirements for the supplemental instructions PDF attachment: 
water flow rate in gallons per minute (``gpm'') for water-cooled and 
water-source units, rated external static pressure (``ESP'') in inches 
of water column for the supply air stream, frequency or control set 
points for variable speed components (e.g., compressors, Variable 
Frequency Drives (``VFDs'')), required dip switch/control settings for 
step or variable components (e.g., reheat or head pressure control 
valves), a statement as to whether the model will operate at test 
conditions without manufacturer programming, and any additional testing 
instructions specified in AHRI 920-2020, if applicable (e.g., supply 
air dry bulb temperatures for ISMRE2 tests, equipment settings for 
airflow, installation priority for split-system units, defrost control 
settings for air-source heat pump units, compressor break-in period, or 
condenser head pressure controls). Additionally, if a variety of 
motors/drive kits are offered for sale as options in the basic model to 
account for varying installation requirements, DOE is proposing that 
the supplemental file also include the model number, the specifications 
of the motor (including efficiency, horsepower, open/closed, and number 
of poles) and the drive kit (including settings) associated with that 
specific motor that were used to determine the certified rating.
    For DX-DOASes with VERS, DOE is proposing the following additional 
content requirements for the supplemental instruction PDF attachment: 
rated ESP in inches of water column for the return air stream, exhaust 
air transfer ratio at the rated supply airflow rate and a neutral 
pressure difference between return and supply airflow (EATR as a 
percent value), sensible and latent effectiveness of the ventilation 
energy recovery system at 75 percent of the nominal supply airflow and 
zero pressure differential, sensible and latent effectiveness of the 
ventilation energy recovery system at 100 percent of the nominal supply 
airflow and zero pressure differential, and any additional testing 
instructions, if applicable (e.g., deactivation of VERS or VERS bypass 
in accordance with section 5.4.3 of AHRI 920-2020).
    DOE seeks comment on its proposal to require supplemental testing 
instruction file contents for DX-DOASes.
2. Reporting Costs and Impacts
    The addition of reporting requirements for DX-DOASes would newly 
require manufacturers to report this information. DOE discusses 
reporting cost impacts corresponding to this proposal in section IV.C 
of this document.
    DOE requests comment on its proposal to add new reporting 
requirements for DX-DOASes.

J. Air Cooled, Three-Phase, Small Commercial Air Conditioners and Heat 
Pumps With a Cooling Capacity of Less Than 65,000 Btu/h and Air-Cooled, 
Three-Phase, Variable Refrigerant Flow Air Conditioners and Heat Pumps 
With a Cooling Capacity of Less Than 65,000 Btu/h

    DOE is proposing to amend the reporting requirements for three-
phase, less than 65,000 Btu/h ACUACs and ACUHPs and three-phase, less 
than 65,000 Btu/h VRF. Three-phase, less than 65,000 Btu/h ACUACs and 
ACUHPs and three-phase, less than 65,000 Btu/h VRF are both categories 
of small commercial package air conditioning and heating equipment. 
Commercial package air-conditioning and heating equipment may be air 
cooled, water cooled, evaporatively cooled, or water source based (not 
including ground water source). This equipment is electrically operated 
and designed as unitary central air conditioners or central air 
conditioning heat pumps for use in commercial applications. 10 CFR 
431.92.
    In the energy conservation standards (``ECS'') final rule published 
in the Federal Register on June 2, 2023 (``June 2023 3-Phase Final 
Rule''), DOE amended energy conservation standards for three-phase, 
less than 65,000 Btu/h ACUACs and ACUHPs and three-phase, less than 
65,000 Btu/h VRF to be in terms of the new cooling and heating metrics, 
SEER2 and HSPF2, respectively, as determined by using the new test 
procedure at appendix F1 to subpart F of 10 CFR part 431. 88 FR 36368. 
Consistent with that final rule, DOE is proposing amendments to the 
reporting requirements for three-phase, less than 65,000 Btu/h ACUACs 
and ACUHPs and three-phase, less than 65,000 Btu/h VRF.
1. Reporting
    Under the existing requirements in 10 CFR 429.67(f)(2)(i) and (ii) 
for three-

[[Page 67477]]

phase, less than 65,000 Btu/h ACUACs and ACUHPs, manufacturers must 
report the seasonal energy efficiency ratio (``SEER'') in British 
thermal units per Watt-hour (``Btu/Wh''), the rated cooling capacity in 
Btu/h, and (for heat pumps) the heating seasonal performance factor 
(``HSPF'') in Btu/Wh.
    Under the existing requirements in 10 CFR 429.67(f)(2)(iii) and 
(iv) for three-phase, less than 65,000 Btu/h VRF, manufacturers must 
report the SEER in Btu/Wh, rated cooling capacity in Btu/h, and (for 
heat pumps) the HSPF in Btu/Wh.
    These requirements provide for certifying compliance with the 
standards applicable to three-phase, less than 65,000 Btu/h ACUACs and 
ACUHPs manufactured on or after January 1, 2017, and the standards 
applicable to three-phase, less than 65,000 Btu/h VRF manufactured on 
or after June 16, 2008. 88 FR 36368, 36389. DOE is proposing to update 
these reporting requirements to align with the amended standards 
adopted by the June 2023 3-Phase Final Rule that apply to three-phase, 
less than 65,000 Btu/h ACUACs and ACUHPs and three-phase, less than 
65,000 Btu/h VRF manufactured on or after January 1, 2025. 88 FR 36368, 
36389. Additionally, DOE is proposing general certification 
requirements for three-phase, less than 65,000 Btu/h ACUACs and ACUHPs 
and three-phase, less than 65,000 Btu/h VRF. DOE discusses these 
proposed updates in the sections as follows.
a. Updating the Certification Requirements To Include the New Metrics, 
SEER2 and HSPF2
    In the June 2023 3-Phase Final Rule, DOE amended energy 
conservation standards for three-phase, less than 65,000 Btu/h ACUACs 
and ACUHPs and three-phase, less than 65,000 Btu/h VRF to be in terms 
of the new cooling and heating metrics, SEER2 and HSPF2. Id. 
Accordingly, in this document, DOE is proposing to update the 
certification requirements at 10 CFR 429.67(f)(2) to include ratings in 
terms of SEER2 and HSPF2, which will become the required reporting 
metrics upon the compliance date of the amended standards. 
Manufacturers may use appendix F1 to certify compliance with the 
amended standards based on SEER2 and HSPF2 prior to the applicable 
compliance date for the amended energy conservation standards.
    DOE seeks comment on its proposal to require the reporting of new 
metrics, such as SEER2 and HSPF2.
b. Aligning Basic Model Number and Individual Model Number(s) Reporting 
Requirements With Single-Phase Products
    DOE proposes to include additional instructions regarding the basic 
model number and individual model number(s) required to be reported 
under 10 CFR 429.12(b)(6); this proposal is consistent with the 
requirement for single-phase products and represents readily available 
information to the manufacturer regarding the requirements for three-
phase equipment.
    Specifically, DOE would require in new subparagraph 10 CFR 
429.67(f)(4) that the basic model number and individual model number(s) 
reported under 10 CFR 429.12(b)(6) consist of the following:

----------------------------------------------------------------------------------------------------------------
                                                                      Individual model number(s)

                                   the basic model.
----------------------------------------------------------------------------------------------------------------

c. Outdoor Units With No Match
    For three-phase, less than 65,000 Btu/h ACUACs and ACUHPs with 
outdoor units having no matching indoor component, DOE proposes 
requiring that in addition to any supplemental testing instructions 
used to satisfy the existing requirement in 10 CFR 429.67(f)(3), 
supplemental testing instructions also include any additional testing 
and testing set up instructions necessary to operate the basic model 
under the required conditions specified by the test procedure. 
Specifically, manufacturers must provide information regarding the 
following characteristics of the indoor coil: the face area, the coil 
depth in the direction of airflow, the fin density (fins per inch), the 
fin material, the fin style, the tube diameter, the tube material, and 
the numbers of tubes high and deep. This proposed requirement would be 
consistent with the 10 CFR 429.16 requirement for single-phase 
products, as well as with the test requirements in the 2019 edition of 
American Society of Heating, Refrigerating and Air-Conditioning 
Engineers (``ASHRAE'') Standard 90.1 ``Energy Standard for Buildings 
Except Low-Rise Residential Buildings'' (``ASHRAE 90.1-2019''), which, 
in turn, references ANSI/AHRI 210/240, ``2023 Standard for Performance 
Rating of Unitary Air-conditioning & Air-source Heat Pump Equipment'' 
(``AHRI 210/240-2023''). Therefore, this information should be readily 
available to manufacturers and will not add manufacturer burden.
d. Sampling Corrections
    Currently, DOE's sampling provisions for three-phase, less than 
65,000 Btu/h ACUACs and ACUHPs and three-phase, less than 65,000 Btu/h 
VRF state that any represented value of cooling capacity and heating 
capacity must each be a self-declared value that is less than or equal 
to the lower of the mean of the sample, or the lower 90 percent 
confidence limit of the true mean (``LCL'') divided by 0.95. 10 CFR 
429.67(c)(2)(ii)(A)(2). The sampling provisions also state that the LCL 
should be calculated using the Student's t-Distribution Values for a 90 
percent one-tailed confidence interval with n-1 degrees of freedom from 
appendix D to subpart B of part 429, where ``n'' is the number of 
samples. Id. However, the appendix containing Student's t-Distribution 
Values has moved to appendix A to subpart B of part 429 (``appendix 
A''). To correct this discrepancy, DOE is proposing to revise 10 CFR 
429.67(c)(2)(ii)(A)(2) to specify that the LCL should be calculated 
using

[[Page 67478]]

the Student's t-Distribution Values for a 90 percent one-tailed 
confidence interval outlined in appendix A.
    DOE seeks comment on its proposal to correct the sampling 
provisions for three-phase, less than 65,000 Btu/h ACUACs and ACUHPs 
and three-phase, less than 65,000 Btu/h VRF to reference appendix A.
2. Reporting Costs and Impacts
    In this NOPR, DOE proposes to align the three-phase, less than 
65,000 Btu/h ACUACs and ACUHPs and three-phase, less than 65,000 Btu/h 
VRF certification reporting requirements with the amended standards 
adopted by the June 2023 3-Phase Final Rule that apply to products 
manufactured on or after January 1, 2025. 88 FR 36368.
    For three-phase, less than 65,000 Btu/h ACUACs and three-phase, 
less than 65,000 Btu/h VRF air conditioners, manufacturers currently 
report SEER in Btu/Wh and rated cooling capacity in Btu/h, but would 
report SEER2 in Btu/Wh in lieu of SEER to conform with the amended 
standards. For three-phase, less than 65,000 Btu/h ACUHPs and three-
phase, less than 65,000 Btu/h VRF heat pumps, manufacturers currently 
report SEER in Btu/Wh, HSPF in Btu/Wh, and rated cooling capacity in 
Btu/h, but would be required to report SEER2 in Btu/Wh and HSPF2 in 
Btu/Wh in lieu of SEER and HSPF to conform with the amended standards.
    DOE has tentatively determined that these proposed amendments would 
not impose additional costs for manufacturers because manufacturers of 
three-phase, less than 65,000 Btu/h ACUACs and ACUHPs and three-phase, 
less than 65,000 Btu/h VRF are already submitting certification reports 
to DOE and should have readily available the information that DOE is 
proposing to collect as part of this rulemaking. DOE does not believe 
the revised reporting requirements will cause any appreciable change in 
reporting burden or hours as compared to what three-phase, less than 
65,000 Btu/h ACUACs and ACUHPs and three-phase, less than 65,000 Btu/h 
VRF manufacturers are doing currently.
    DOE requests comment on the certification reporting costs of the 
amendments proposed for three-phase, less than 65,000 Btu/h ACUACs and 
ACUHPs and three-phase, less than 65,000 Btu/h VRF.

K. Commercial Water Heating Equipment

    DOE is proposing to amend the reporting requirements for commercial 
water heating equipment. EPCA prescribes energy conservation standards 
for several classes of CWH equipment manufactured on or after January 
1, 1994. (42 U.S.C. 6313(a)(5)) DOE codified these standards in its 
regulations for CWH equipment at 10 CFR 431.110. However, when 
codifying these standards from EPCA, DOE inadvertently omitted the 
standards put in place by EPCA for electric instantaneous water 
heaters, which are instantaneous water heaters with a rated input both 
greater than 12 kW and not less than 4,000 Btu/h per gallon of stored 
water (see 10 CFR 431.102). Therefore, in a NOPR published on May 19, 
2022 (``May 2022 CWH NOPR''), DOE proposed to codify these standards in 
its regulations at 10 CFR 431.110. 87 FR 30610, 30622.
    DOE is proposing to establish reporting requirements for commercial 
electric instantaneous water heaters (except for residential-duty 
commercial electric instantaneous water heaters for which certification 
is already addressed in 10 CFR 429.44), consistent with the May 2022 
CWH NOPR.
    Additionally, DOE is proposing to add reporting requirements for 
commercial electric storage water heaters to ensure that the input 
rating of all certified models exceeds the 12 kW threshold that is part 
of the definition of electric storage water heaters at 10 CFR 431.102.
1. Reporting
    Under the existing requirements in 10 CFR 429.44, manufacturer 
certification reports for commercial water heating equipment are not 
required to include information about electric instantaneous water 
heaters. 10 CFR 429.44(c)(2).
    Therefore, for commercial electric instantaneous water heaters of 
all storage volumes (except for residential-duty commercial electric 
instantaneous water heaters), DOE is proposing to add certification 
requirements for thermal efficiency, storage volume, rated input, and 
whether the storage volume is determined using a weight-based test (in 
accordance with 10 CFR 431.106) or the calculation-based method (in 
accordance with 10 CFR 429.72(e), as discussed in the following 
paragraph). For electric instantaneous water heaters with storage 
volume greater than or equal to 10 gallons (and thus subject to a 
standby loss standard), DOE is also proposing to require that the 
following information be certified to ensure compliance with standby 
loss standards and to enable DOE to understand how the standby test was 
conducted for each basic model: (1) standby loss, (2) whether the water 
heater initiates heating element operation based on a temperature-
controlled call for heating that is internal to the water heater, (3) 
whether the water heater includes an integral pump purge functionality, 
and (4) the default duration of the pump off delay (for models equipped 
with integral pump purge).
    Similarly, DOE is proposing to allow use of a calculation-based 
method for determining the storage volume of electric instantaneous 
water heaters that is the same as the method for gas-fired and oil-
fired instantaneous water heaters and hot water supply boilers found at 
10 CFR 429.72(e). Furthermore, DOE is proposing to clarify that the 
method for calculating volume for instantaneous water heaters found at 
10 CFR 429.72(e) does not apply to storage-type instantaneous water 
heaters.
    Finally, for commercial electric storage water heaters, DOE is 
proposing to add a certification requirement for rated input to ensure 
that the input rating of all certified models exceeds the 12 kW 
threshold that is part of the definition of electric storage water 
heaters at 10 CFR 431.102. DOE proposes that manufacturers would be 
required to comply with the certification requirement beginning on the 
date of the next annual filing of certification reports required for 
CWH equipment following the publication of a final rule.\17\
---------------------------------------------------------------------------

    \17\ The annual certification report filings for commercial 
water heating equipment are due on May 1. See 10 CFR 429.12.
---------------------------------------------------------------------------

    DOE seeks comment on its proposal to require the reporting of 
thermal efficiency, storage volume, rated input, and whether the 
storage volume is determined using a weight-based test or the 
calculation-based method for commercial electric instantaneous water 
heaters of all storage volumes (except for residential-duty commercial 
electric instantaneous water heaters). DOE also seeks comment on its 
proposal to require the reporting of standby loss, whether the water 
heater initiates heating element operation based on a temperature-
controlled call for heating that is internal to the water heater, 
whether the water heater includes an integral pump purge functionality, 
and the default duration of the pump off delay (for models equipped 
with integral pump purge) for electric instantaneous water heaters with 
storage volume greater than or equal to 10 gallons. Additionally, DOE 
seeks comment on its proposed calculation-based method for determining 
storage volume of electric instantaneous water heaters.
    DOE seeks comment on its proposal to add a requirement for the 
reporting of rated input for commercial electric storage water heaters.

[[Page 67479]]

2. Reporting Costs and Impacts
    In this NOPR, DOE proposes to align the certification reporting 
requirements for commercial electric instantaneous water heaters 
(except for residential-duty commercial electric instantaneous water 
heaters) with the energy conservation standards for such equipment as 
required by EPCA, and as proposed to be codified at 10 CFR 431.110 by 
the May 2022 CWH NOPR.
    Manufacturers of commercial electric instantaneous water heaters 
(except for residential-duty commercial electric instantaneous water 
heaters) do not currently report any information about the performance 
or characteristics of such equipment, but would be required to report 
thermal efficiency, storage volume, rated input, and whether the 
storage volume is determined using a weight-based test (in accordance 
with 10 CFR 431.106) or the calculation-based method (in accordance 
with 10 CFR 429.72(e)).
    Additionally, for electric instantaneous water heaters with storage 
volume greater than or equal to 10 gallons (and thus subject to a 
standby loss standard), manufacturers would also be required to report 
standby loss, whether the water heater initiates heating element 
operation based on a temperature-controlled call for heating that is 
internal to the water heater, whether the water heater includes an 
integral pump purge functionality, and the default duration of the pump 
off delay (for models equipped with integral pump purge).
    Any manufacturer of commercial electric instantaneous water heaters 
would be required to begin submitting certification reports. Costs 
associated with the proposed updates to reporting requirements are 
discussed in section IV.C of this document.
    In this NOPR, DOE also proposes to amend the certification 
reporting requirements for commercial electric storage water heaters to 
require manufacturers to report rated input.
    DOE has tentatively determined that these proposed amendments would 
not impose additional costs for manufacturers of commercial electric 
storage water heaters because they are already submitting certification 
reports to DOE and should have readily available the information that 
DOE is proposing to collect as part of this rulemaking. DOE does not 
believe the revised reporting requirements will cause any appreciable 
change in reporting burden or hours as compared to what commercial 
electric storage water heaters manufacturers are currently doing today.
    DOE requests comment on the certification reporting costs of the 
amendments proposed for commercial electric instantaneous water heaters 
and commercial electric storage water heaters.

L. Automatic Commercial Ice Makers

    DOE is proposing to amend the reporting requirements for ACIMs, 
which are factory-made assemblies (not necessarily shipped in 1 
package) that (1) consist of a condensing unit and ice-making section 
operating as an integrated unit, with means for making and harvesting 
ice; and (2) may include means for storing ice, dispensing ice, or 
storing and dispensing ice. 10 CFR 431.132. In the November 1, 2022 
Automatic Commercial Ice Maker Test Procedure Final Rule (``November 
2022 ACIM Final Rule''), DOE replaced the terms ``maximum energy use'' 
and ``maximum condenser water use'' with ``energy use'' and ``condenser 
water use,'' respectively, for ACIMs. 87 FR 65856, 56892. Consistent 
with that rulemaking, DOE is proposing amendments to the reporting 
requirements for ACIMs.
1. Reporting
    Under the existing requirements in 10 CFR 429.45, manufacturers 
must report maximum energy use in kilowatt hours (``kWh'') per 100 
pounds of ice, maximum condenser water use in gallons per 100 pounds of 
ice, harvest rate in pounds of ice per 24 hours, type of cooling, and 
equipment type. 10 CFR 429.45(b)(2). These requirements provide for 
certifying compliance with the standards applicable to ACIMs 
manufactured on or after January 28, 2018. 10 CFR 431.136(c) and (d). 
DOE is proposing to update these requirements and align the reporting 
requirements with the November 2022 ACIM Final Rule and proposing 
general certification requirements for ACIMs. DOE discusses these 
proposed updates in the sections as follows.
a. Energy and Water Condenser Use
    For ACIMs, the current reporting requirements include maximum 
energy use in kWh per 100 pounds of ice and maximum condenser water use 
in gallons per 100 pounds of ice. 10 CFR 429.45(b)(2). In the November 
2022 ACIM Final Rule, DOE determined that the reference to ``maximum 
energy use'' and ``maximum condenser water use'' in 10 CFR 429.45 could 
be misinterpreted to refer to the energy and water conservation 
standard levels for that basic model (i.e., the maximum allowable 
energy and maximum allowable condenser water use), as opposed to the 
tested performance. 87 FR 65856, 65891. Therefore, in that same rule, 
for consistency and clarity, DOE replaced the term ``maximum energy 
use'' with the term ``energy use'' and the term ``maximum condenser 
water use'' with the term ``condenser water use.'' Id. at 87 FR 65892. 
In addition, values of both energy and condenser water consumption are 
relevant for ACIMs. Id. at 87 FR 65891. As such, DOE modified the 
language at 10 CFR 429.45 to specify expressly that the sampling plan 
at 10 CFR 429.45(a)(2)(i) applies both to measures of energy and 
condenser water use for which consumers would favor lower values. Id. 
at 87 FR 65892.
    Similarly, 10 CFR 431.132 included a definition for the term 
``maximum condenser water use.'' This language may also be 
misinterpreted to refer to the condenser water conservation standard 
level for a basic model as opposed to the tested condenser water use. 
Therefore, in the November 2022 ACIM Final Rule, DOE modified the term 
and definition of ``maximum condenser water use'' to instead refer to 
the term ``condenser water use.'' Id.
    In the November 2022 ACIM Final Rule, DOE did not revise the 
reporting requirements in 10 CFR 429.45 to remove the term ``maximum'' 
and align the requirements with the newly adopted definitions for 
``energy use'' and ``condenser water use.'' Id. at 87 FR 65897. As a 
result, DOE is proposing to update the reporting requirements to 
specify ``energy use'' and ``condenser water use'' in this document.
    DOE seeks comment on its proposal to align ACIM reporting 
requirement terminology with the amended terms.
b. Rounding Requirements
    DOE currently requires test results for ACIMs to be rounded, as 
outlined in the ACIMs test procedure. 10 CFR 431.134(g). However, the 
certification requirements in 10 CFR 429.45 do not specify how values 
calculated in accordance with 10 CFR 429.45(a) would be rounded for 
reporting per 10 CFR 429.45(b). To ensure consistency among ACIM 
certification reports, DOE proposes that any reported values be rounded 
consistent with the rounding requirements for individual test results. 
Specifically, DOE proposes to require that reported values be rounded 
as follows: energy use to the nearest 0.01 kWh/100 lb, condenser water 
use to the nearest gal/100 lb, and harvest rate to the nearest 1 lb/24 
h (for ACIMs with harvest rates greater than 50 lb/24 h) or to the 
nearest 0.1 lb/24 h (for ACIMs with harvest rates less than or equal to 
50 lb/24 h).

[[Page 67480]]

    DOE seeks comment on its proposal to establish rounding 
requirements for ACIMs.
c. Sampling Corrections
    Currently, DOE's sampling provisions for ACIMs state that any 
represented value of energy use, condenser water use, or other measure 
of consumption of a basic model for which consumers would favor lower 
values shall be greater than or equal to the higher of the mean of the 
sample, or the upper 95 percent confidence limit of the true mean 
(``UCL'') divided by 1.10. 10 CFR 429.45(a)(2). The sampling provisions 
also state that the UCL should be calculated using the Student's t-
Distribution Values for Certification Testing for a 95 percent two-
tailed confidence interval with n-1 degrees of freedom from appendix A, 
where ``n'' is the number of samples. Id. However, appendix A outlines 
Student's t-Distribution Values that are based on a one-tailed 
confidence interval, rather than the two-tailed confidence interval 
specified in 10 CFR 429.45(a)(2)(ii). To correct this discrepancy, DOE 
is proposing to revise 10 CFR 429.45(a)(2)(ii) to specify that the UCL 
should be calculated using the Student's t-Distribution Values for 
Certification Testing for a 95 percent one-tailed confidence interval 
outlined in appendix A.
    DOE seeks comment on its proposal to correct the sampling 
provisions for ACIMs.
2. Reporting Costs and Impacts
    In this NOPR, DOE proposes to align ACIM certification reporting 
requirements with the amended terms adopted in the November 2022 ACIM 
Final Rule. For ACIMs, manufacturers currently report maximum energy 
use and maximum condenser water and under the proposed amended 
requirements would report energy use and condenser water use, which are 
substantially similar to the previous requirement.
    DOE has tentatively determined that these proposed amendments would 
not impose additional costs for manufacturers because manufacturers of 
ACIMs are already submitting certification reports to DOE containing 
these values and should have readily available the information that DOE 
is proposing to collect as part of this proposed rulemaking. DOE does 
not believe the revised reporting requirements will cause any 
appreciable change in reporting burden or hours as compared to what 
ACIM manufacturers are doing currently.
    DOE requests comment on the certification reporting costs of the 
amendments proposed for ACIMs.

M. Walk-In Coolers and Freezers

    DOE is proposing to amend the reporting requirements for walk-in 
coolers and walk-in freezers (``walk-ins''), which are enclosed storage 
spaces refrigerated to temperatures, respectively, above and at or 
below 32 [deg]F that can be walked into and have a total chilled 
storage area of less than 3,000 square feet. The terms ``walk-in 
cooler'' and ``walk-in freezer'' do not include products designed and 
marketed exclusively for medical, scientific, or research purposes. 10 
CFR 431.302 In the test procedure final rule published on May 4, 2023 
(``May 2023 Walk-ins TP Final Rule''), DOE amended the test procedure 
provisions for walk-ins. 88 FR 28780. Consistent with the May 2023 
Walk-ins TP Final Rule, DOE is proposing amendments to the reporting 
requirements in this NOPR.
1. Reporting
    Under the existing requirements in 10 CFR 429.53, manufacturers 
must report the following public information:
    (1) For all walk-in doors: the door type, R-value of the door 
insulation, a declaration that the manufacturer has incorporated the 
applicable design requirements, door energy consumption, and rated 
surface area in square feet. 10 CFR 429.53(b)(2)(i) and (b)(3)(i).
    (2) For walk-in doors with transparent reach-in doors and windows, 
the glass type of the doors and windows (e.g., double-pane with heat 
reflective treatment, triple-pane glass with gas fill), and the power 
draw of the antisweat heater in watts per square foot of door opening. 
10 CFR 429.53 (b)(i).
    (3) For walk-in panels: the insulation R-value. 10 CFR 
429.53(b)(ii).
    (4) For walk-in refrigeration systems: the installed motor's 
function purpose (i.e., evaporator fan motor or condenser fan motor), 
its rated horsepower, a declaration that the manufacturer has 
incorporated the applicable walk-in-specific design requirements into 
the motor, annual walk-in energy factor (``AWEF''), net capacity, the 
configuration tested for certification (e.g., condensing unit only, 
unit cooler only, single-packaged dedicated system, or matched pair), 
and if an indoor dedicated condensing unit is also certified as an 
outdoor dedicated condensing unit (and, if so, the basic model number 
for the outdoor dedicated condensing unit). 10 CFR 429.53(b)(2)(iii), 
(b)(3)(ii), (b)(5).
    Under the existing requirements in 10 CFR 429.53, manufacturers 
must report the following non-public information for all walk-in doors: 
(1) rated power of each light, heater wire, and/or other electricity 
consuming device; and (2) whether such device(s) has/have a timer, 
control system, or other demand-based control that reduces the device's 
power consumption. 10 CFR 429.53(b)(4)(i).
    These requirements provide for certifying compliance with the 
standards applicable to walk-in doors, panels, and medium temperature 
dedicated condensing units (including medium temperature single-
packaged dedicated systems and matched pairs) manufactured on or after 
June 5, 2017 and with the standards applicable to walk-in low 
temperature dedicated condensing units (including low temperature 
single-packaged dedicated systems and matched pairs), low temperature 
unit coolers, and medium temperature unit coolers manufactured on or 
after July 10, 2020. DOE is proposing to update these requirements and 
align the reporting requirements with the May 2023 Walk-ins TP Final 
Rule. DOE discusses these proposed updates in the sections as follows.
a. Combining the Publicly Required Reporting Requirements in 10 CFR 
429.53(b)(2), 429.53 (b)(3), and 429.53(b)(5)
    The current reporting requirements at 10 CFR 429.53(b) specify 
public reporting requirements in three paragraphs--(b)(2), (b)(3), and 
(b)(5)--based on whether the reporting requirement was submitted before 
or after June 5, 2017. Given this date has passed, DOE is proposing to 
combine the public product-specific reporting requirements at 10 CFR 
429.53(b)(2) and move the non-public product-specific reporting 
requirements from 10 CFR 429.53(b)(4) to 10 CFR 429.53(b)(3).
b. CO2 Systems
    DOE has granted waivers to Heat Transfer Products Group, Hussmann, 
KeepRite, and RefPlus for an alternate test procedure for specific unit 
cooler basic models that utilize CO2 as a refrigerant.\18\ 
The alternate test procedure provided in these waivers modifies the 
test condition values to reflect typical operating conditions for a 
transcritical \19\ CO2 booster system.

[[Page 67481]]

Specifically, the waiver test procedures require that CO2 
unit cooler testing is conducted at a liquid inlet saturation 
temperature of 38 [deg]F and a liquid inlet subcooling temperature of 5 
[deg]F.
---------------------------------------------------------------------------

    \18\ HTPG Decision and Order, 86 FR 14887 (Mar. 19, 2021); 
Hussmann Decision and Order, 86 FR 24606 (May 7, 2021); KeepRite 
Decision and Order, 86 FR 24603 (May 7, 2021); RefPlus Interim 
Waiver, 86 FR 43633 (Aug. 10, 2021).
    \19\ CO2 refrigeration systems are transcritical 
because the high-temperature refrigerant that is cooled by ambient 
air is in a supercritical state, above the 87.8 [deg]F critical 
point temperature, above which the refrigerant cannot exist as 
separate vapor and liquid phases.
---------------------------------------------------------------------------

    In the May 2023 Walk-ins TP Final Rule, DOE amended appendix C to 
include the alternate test conditions specified in the waivers. DOE 
also adopted these requirements into the new appendix C1. 88 FR 28780, 
28809. Additionally, in the May 2023 Walk-ins TP Final Rule, DOE 
defined a ``CO2 unit cooler'' as ``a unit cooler that 
includes a nameplate listing only CO2 as an approved 
refrigerant''. 88 FR 28780, 28790.
    Accordingly, DOE proposes to amend the public reporting 
requirements at 10 CFR 429.53(b)(2)(iii) to require that manufacturers 
report whether a given basic model meets the definition of a 
CO2 unit cooler as defined in the May 2023 Walk-ins TP Final 
Rule. DOE proposes that manufacturers would be required to comply with 
the proposed reporting requirement beginning on the next certification 
report annual filing date required for walk-in components following the 
publication of this rule, if finalized.\20\
---------------------------------------------------------------------------

    \20\ The annual certification report filings for walk-ins are 
due no later than August 1. See 10 CFR 429.12, Table 1 to paragraph 
(d).
---------------------------------------------------------------------------

    DOE seeks comment on its proposal to require the reporting of 
whether a basic model meets the definition of a CO2 unit 
cooler.
c. Detachable Single-Packaged Dedicated Systems and Attached Split 
System
    In the May 2023 Walk-ins TP Final Rule, DOE defined a ``detachable 
single-packaged dedicated system'' as a system consisting of a 
dedicated condensing unit and an insulated evaporator section in which 
the evaporator section is designed to be installed external to the 
walk-in enclosure and circulating air through the enclosure wall, and 
the condensing unit is designed to be installed either attached to the 
evaporator section or mounted remotely with a set of refrigerant lines 
connecting the two components. 88 FR 28780, 28790. Since detachable 
single-packaged dedicated systems have thermal losses similar to those 
for single-packaged dedicated systems, DOE adopted the air enthalpy 
test procedure for single-packaged dedicated systems in the May 2023 
Walk-ins TP Final Rule. 88 FR 28780, 28815-28816.
    Additionally, DOE defined an ``attached split system'' in the May 
2023 Walk-ins TP Final Rule as a matched pair refrigeration system that 
is designed to be installed with the evaporator entirely inside the 
walk-in enclosure and the condenser entirely outside the walk-in 
enclosure, where the evaporator and condenser are permanently connected 
with structural members extending through the walk-in wall. 88 FR 
28780, 28790. DOE has confirmed through testing that these systems 
still experience some heat leakage when compared to traditionally 
installed systems that have the dedicated condensing unit and the unit 
cooler in separate housings. This heat leakage has not been fully 
studied, however, so in the May 2023 Walk-ins TP Final Rule, DOE 
specified that these systems should be tested as a matched pair using 
refrigerant enthalpy methods. 88 FR 28780, 28816.
    Although both detachable single-packaged dedicated systems and 
attached split systems would be considered a ``single-packaged 
dedicated system,'' the two would be tested differently. Some of the 
previously discussed test procedure waivers specify basic models that 
meet the definition of a detachable single-packaged dedicated system or 
an attached split system. To ensure appropriate testing and consistent 
reporting, it is important that these units be identified during 
certification.
    Accordingly, DOE proposes to amend the public reporting 
requirements at 10 CFR 429.53(b)(2)(iii) to require that manufacturers 
report whether a given basic model meets the definition of a 
``detachable single-packaged dedicated system'' or an ``attached split 
system'' as defined in the May 2023 Walk-ins TP Final Rule. DOE 
proposes that manufacturers would be required to comply with the 
proposed reporting requirement beginning on the next certification 
report annual filing date required for walk-in components following the 
publication of this rule, if finalized.
    DOE seeks comment on its proposal to require the reporting of 
whether a basic model meets the definition of a detachable single-
packaged dedicated system or an attached split system.
d. Head Pressure Control
    In the May 2023 Walk-ins TP Final Rule, DOE adopted refrigerant 
charging provisions for walk-in dedicated condensing systems that use 
valves to ``flood'' the condenser with liquid refrigerant to maintain 
sufficiently high condensing temperature under cold air temperatures. 
88 FR 28780, 28804-28806. Specifically, DOE noted that charging in the 
``C'' test condition rather than the ``A'' test condition is 
appropriate for dedicated condensing systems (dedicated condensing 
units, matched systems, and single-packaged dedicated systems) that use 
a flooded condenser design. Id. However, for dedicated condensing 
systems that use fan controls to maintain condensing temperature for 
low ambient operating conditions, the test procedure specifies charging 
at the ``A'' test condition. 88 FR 28780, 28804-28806.
    Accordingly, DOE proposes to amend the non-public reporting 
requirements at 10 CFR 429.53(b)(3)(ii) \21\ to require that 
manufacturers report whether a given dedicated condensing system basic 
model is sold with flooded head pressure controls for maintaining 
condensing temperature at low ambient temperatures. DOE proposes that 
manufacturers would be required to comply with the proposed reporting 
requirement beginning on the next certification report annual filing 
date required for walk-in components following the publication of this 
rule, if finalized.
---------------------------------------------------------------------------

    \21\ Note that currently 10 CFR 429.53(b)(3) specifies public 
reporting requirements. In this NOPR, DOE is proposing to revise 10 
CFR 429.53(b) such that paragraph (b)(2) specifies the public 
reporting requirements and paragraph (b)(3) specifies non-public 
reporting requirements.
---------------------------------------------------------------------------

    DOE seeks comment on its proposal to require the reporting of 
whether a dedicated condensing system basic model includes flooded head 
pressure controls.
e. Compressor Break-In
    Although the DOE test procedure for walk-in refrigeration systems 
does not require a compressor ``break-in'' period, DOE recognizes that 
walk-in refrigeration manufacturers may routinely break-in the 
refrigeration system compressor for some time prior to conducting 
testing. This break-in period can reduce variation in compressor 
performance.
    In the June 8, 2016, central air conditioners and heat pumps test 
procedure final rule, DOE noted that the most significant improvements 
in both compressor performance and reduction in variation among 
compressor models occur during roughly the first 20 hours of run time. 
81 FR 36992, 37034. Ultimately, DOE adopted the provision to limit the 
optional break-in period to 20 hours to achieve the most uniform 
compressor performance while limiting test burden. Id. DOE additionally 
included provisions for manufacturers to have the option to report the 
use of a break-in period and its duration as

[[Page 67482]]

part of the test data underlying their product certifications, the use 
of the same break-in period specified in product certifications for 
testing conducted by DOE, and the use of the 20 hours break-in period 
for products certified using an alternative efficiency determination 
method (``AEDM''). 81 FR 36992, 37033.
    Other DOE-regulated equipment, such as dedicated outdoor air 
systems (see appendix B to subpart F of 10 CFR part 431 and discussion 
at 87 FR 45164, 45177-45178), single package vertical air conditioners 
and heat pumps (``SPVUs'') (see section I of subpart F to 10 CFR part 
431) and air-cooled unitary air conditions and heat pumps (``CUACs'') 
(see 10 CFR 431.96) include required or optional provisions for 
compressor break-in either as part of the test procedure or as a 
certification option, so that any potential enforcement testing uses 
conditions similar to those used for rating a given unit. Whether 
required or optional, break-in duration is limited to a maximum of 20 
hours for dedicated outdoor air supply units, SPVUs, and CUACs.
    Accordingly, DOE proposes to amend the non-public reporting 
requirements at 10 CFR 429.53(b)(3)(ii) \22\ to provide an option for 
manufacturers to report the compressor break-in period, in hours, used 
to obtain a basic model's certified rating; however, the break-in 
duration may not exceed 20 hours in length. DOE proposes that 
manufacturers would be required to comply with the proposed reporting 
requirement beginning on the next certification report annual filing 
date required for walk-in components following the publication of this 
rule, if finalized.
---------------------------------------------------------------------------

    \22\ Note that currently 10 CFR 429.53(b)(3) specifies public 
reporting requirements. In this NOPR, DOE is proposing to revise 10 
CFR 429.53(b) such that paragraph (b)(2) specifies public reporting 
requirements and paragraph (b)(3) specifies non-public reporting 
requirements.
---------------------------------------------------------------------------

    DOE seeks comment on its proposal to amend the reporting 
requirements and provide an option for manufactures to report 
compressor break-in.
f. Supplemental Testing Instructions
    As discussed previously, DOE requires manufacturers of covered 
commercial HVAC equipment types to submit supplemental information 
regarding additional testing instructions, if applicable, and they must 
also specify which, if any, special features were included to rate a 
basic model. DOE also requires supplemental testing instructions from 
manufacturers of commercial warm air furnaces (see 10 CFR 
429.41(b)(4)), commercial refrigeration equipment (see 10 CFR 
429.42(b)(4)), and commercial water heating equipment (see 10 CFR 
429.44(c)(4)). The supplemental information submitted in PDF format 
provides information to allow for third-party laboratories to complete 
a valid test according to the DOE test procedure.
    Consistent with its requirements for other commercial equipment, 
DOE proposes to require that, if such information would be needed for a 
third party to independently run a valid test, manufacturers must 
submit supplemental testing instructions at the time each basic model 
is certified. Supplemental testing instructions for walk-ins might 
include (but are not limited to) specific charging instructions, 
control of fan cycling at specific test conditions, and type of 
expansion valve. Consistent with the supplemental testing instructions 
DOE has established for other commercial equipment, DOE notes that any 
supplemental information for testing walk-ins would need to be 
consistent with manufacturer installation instructions associated with 
the equipment under test. See section 3.2.6 of appendix C to subpart R 
of 10 CFR part 431 and section 3.5.2.4 of appendix C1 to subpart R of 
10 CFR part 431. Prior to testing any walk-in refrigeration system 
basic model under its enforcement provisions, DOE would determine if 
supplemental testing instructions were included with certification of 
the basic model. If supplemental testing instructions were included 
with certification, DOE would review these instructions and compare 
them to the manufacturer's installation instructions. Once DOE has 
determined that the supplemental instructions are consistent with the 
manufacturer's installation instructions, DOE would instruct the third-
party test lab to incorporate the supplemental testing instructions 
into its test plan.
    DOE notes that manufacturers would need to provide the complete 
name of the PDF containing the supplemental testing instructions as 
part of the certification report. If the manufacturer changes the 
supplemental testing instructions and as a result changes the file 
name, then the manufacturer must update the certification report.
    DOE proposes to require that, if necessary to run a valid test, 
manufacturers must submit supplemental testing instructions at the time 
each basic model is certified. DOE proposes that manufacturers would be 
required to comply with the proposed reporting requirement beginning on 
the next certification report annual filing date required for walk-in 
components following the publication of this rule, if finalized.
    DOE seeks comment on its proposal to require, if necessary to run a 
valid test, supplemental testing information as a PDF file at the time 
of certification.
g. Anti-Sweat Heater Wire With Controls
    For walk-ins with transparent reach-in doors, EPCA prescribes 
specific ASH-related requirements: (1) walk-ins without anti-sweat 
heater controls must have a heater power draw of no more than 7.1 or 
3.0 watts per square foot of door opening for freezers and coolers, 
respectively; (2) walk-ins with anti-sweat heater controls must either 
have a heater power draw of no more than 7.1 or 3.0 watts per square 
foot of door opening for freezers and coolers, respectively; or (3) the 
anti-sweat heater controls must reduce the energy use of the heater in 
a quantity corresponding to the relative humidity of the air outside 
the door or to the condensation on the inner glass pane. See 42 U.S.C. 
6313(f)(3)(C)-(D). These requirements are also codified at 10 CFR 
431.306(b)(3)-(4).
    The current test procedure assigns percent time off (``PTO'') 
values to various walk-in door components, including anti-sweat 
heaters, to reflect the hours in a day that an electricity-consuming 
device operates at its full rated or certified power. For walk-in 
cooler doors with ASH controls, the PTO value is 75 percent and for 
walk-in freezer doors with ASH controls, the PTO value is 50 percent. 
For doors without ASH controls, the PTO is 0 percent. The test 
procedure does not distinguish between types of ASH controls, just the 
presence of them.
    DOE recognizes that walk-in coolers and freezers may be installed 
in a variety of environments, including different geographical climate 
zones, different indoor building installations, and even outdoor 
installations. Thus, walk-ins may experience a wide variety of ambient 
conditions. Consumers looking to purchase walk-in doors with ASH 
controls may benefit from publicly available information on the 
conditions at which the ASH is activated based on any controls provided 
as part of the door.
    Additionally, during enforcement testing, DOE calculates the door's 
energy consumption using the input power listed on the nameplate of 
each electricity-consuming device shipped with the door. In the absence 
of a value listed on the nameplate, DOE uses the device's rated input 
power included in

[[Page 67483]]

the door's certification report. In the absence of either a nameplate 
or certified value, DOE may measure the input power for the purposes of 
calculating a door's energy consumption. 10 CFR 429.134(q)(4). 
Manufacturers are required to certify to DOE whether each electricity-
consuming device, including ASH, has controls. 10 CFR 429.53(b)(4)(i). 
If there is no certification for the basic model, it can be difficult 
to discern whether the unit has controls without destroying the door.
    For these reasons, DOE is proposing that manufacturers of doors 
with ASH controls certify the conditions (i.e., temperature, humidity, 
etc.) at which the controls activate the ASH wire. DOE proposes that 
manufacturers would be required to comply with the proposed reporting 
requirement beginning on the next certification report annual filing 
date required for walk-in components following the publication of this 
rule, if finalized.
    DOE seeks comment on its proposal to require the reporting of the 
conditions at which the controls activate the ASH wire for walk-in 
doors with ASH controls.
h. Door Conduction Load
    DOE's test procedure for measuring walk-in door energy consumption 
accounts for thermal conduction through the door and the direct and 
indirect electricity use of any electrical components associated with 
the door. 10 CFR 431.304(b)(1)-(2) and 10 CFR part 431, subpart R, 
appendix A.
    The direct and indirect electricity use of the electrical 
components associated with the door is based on the certified or 
nameplate input power values of each component, which are certified to 
DOE as non-public information. DOE does not, at present, require 
certification of the thermal conduction through the door.
    In this NOPR, DOE is proposing to require certification of thermal 
conduction load through the door in Btu/h. This would be added to the 
non-public reporting requirements in 10 CFR 429.53(b)(3)(i). 
Manufacturers are already calculating conduction load as part of the 
current test procedure at sections 6.2.1 and 6.3.1 of appendix A to 
subpart R of 10 CFR part 431 for display doors and non-display doors, 
respectively. DOE notes that the conduction load is required for 
calculating the daily energy consumption. DOE has evaluated the 
theoretical thermal conduction for all walk-in doors certified to DOE 
and found in some cases that the calculated values may not be 
consistent with the values that would be expected based on the 
currently reported data (i.e., wattage, presence of controls) for the 
door's electricity-consuming devices. To remedy this situation, DOE is 
proposing that walk-in door manufacturers certify thermal conduction 
load as non-public data, in addition to the requirements already listed 
in 10 CFR 429.53(b)(3)(i). DOE proposes that manufacturers would be 
required to comply with the proposed reporting requirement beginning on 
the next certification report annual filing date required for walk-in 
components following the publication of this rule, if finalized.
    DOE requests comment on its proposed additional certification 
reporting requirements for walk-in doors and refrigeration systems.
2. Reporting Costs and Impacts
    In this NOPR, DOE proposes to align walk-in certification reporting 
requirements with the test procedure requirements applicable to walk-
ins manufactured on and after October 31, 2023. For all walk-in doors, 
manufacturers currently report the door type, R-value of the door 
insulation, a declaration that the manufacturer has incorporated the 
applicable design requirements, door energy consumption, rated surface 
area, rated power of each light, heater wire, and/or other electricity-
consuming device and whether such device(s) has a timer, control 
system, or other demand-based control that reduces the device's power 
consumption. For transparent reach-in display doors and windows, 
manufacturers must currently also report the glass type of the doors 
and windows), and the power draw of the ASH. Manufacturers would 
additionally report the conduction load through the door, whether the 
basic model uses self-regulating heater wire, and, if so, specify the 
temperature at which the wire engages if the proposed amendments are 
adopted.
    For walk-in refrigeration systems, manufacturers currently report 
the installed motor's function purpose (i.e., evaporator fan motor or 
condenser fan motor), its rated horsepower, a declaration that the 
manufacturer has incorporated the applicable walk-in-specific design 
requirements into the motor, AWEF, net capacity, the configuration 
tested for certification (e.g., condensing unit only, unit cooler only, 
single-packaged dedicated system, or matched pair), and if an indoor 
dedicated condensing unit is also certified as an outdoor dedicated 
condensing unit (and, if so, the basic model number for the outdoor 
dedicated condensing unit). If the proposed amendments are adopted 
manufacturers would additionally report whether the basic model is 
designed for use with CO2 as a refrigerant, whether a 
dedicated condensing system has flooded head pressure control, and 
whether a compressor break-in period was used, and if so, the duration 
of the break-in period. Additionally, manufacturers would be required 
to submit supplemental testing instructions in PDF format if these 
instructions are necessary to run a valid test. DOE has tentatively 
determined that these proposed amendments would not impose additional 
costs for manufacturers because manufacturers of walk-ins are already 
submitting certification reports to DOE and should have readily 
available the information that DOE is proposing to collect as part of 
this rulemaking. DOE does not believe the revised reporting 
requirements will cause any appreciable change in reporting burden or 
hours as compared to what walk-in manufacturers are currently doing 
today.
    DOE requests comment on the certification reporting costs of the 
amendments proposed for walk-ins.
3. Labeling
    If the Secretary has prescribed test procedures for any class of 
covered equipment, a labeling rule applicable to such class of covered 
equipment must be prescribed. See 42 U.S.C. 6315(a). EPCA, however, 
also sets out certain criteria that must be met prior to prescribing a 
given labeling rule. Specifically, to establish these requirements, DOE 
must determine that: (1) labeling in accordance with section 6315 is 
technologically and economically feasible with respect to any equipment 
class; (2) significant energy savings will likely result from such 
labeling; and (3) labeling in accordance with section 6315 is likely to 
assist consumers in making purchasing decisions. (See 42 U.S.C. 
6315(h))
    If these criteria are met, EPCA specifies certain aspects of 
equipment labeling that DOE must consider in any rulemaking 
establishing labeling requirements for covered equipment. At a minimum, 
such labels must include the energy efficiency of the affected 
equipment as tested under the prescribed DOE test procedure. The 
labeling provisions may also consider the addition of other 
requirements, including: (1) directions for the display of the label; 
(2) a requirement to display on the label additional information 
related to energy efficiency or energy consumption, which may include

[[Page 67484]]

instructions for maintenance and repair of the covered equipment, as 
necessary, to provide adequate information to purchasers; and (3) 
requirements that printed matter displayed or distributed with the 
equipment at the point of sale also include the information required to 
be placed on the label. (42 U.S.C. 6315(b) and 42 U.S.C. 6315(c))
    DOE previously established labeling requirements for walk-in 
components, codified at 10 CFR 431.305, in a final rule published on 
December 28, 2016 (``December 2016 Walk-in Final Rule''). 81 FR 95758, 
95802. For walk-in panels, DOE had initially proposed in the NOPR 
leading to the aforementioned final rule to include the date of 
manufacture on the nameplate of a panel. 81 FR 54925, 54942 (Aug. 17, 
2016). At the time, DOE estimated the total cost of applying labels 
specifically to non-display doors and panels, which may include date of 
manufacture, to be less than 0.1 percent of an average manufacturer's 
annual revenue. Id. In consideration of stakeholder comments indicating 
that affixing a panel label with date of manufacture was not 
technologically feasible, in the December 2016 walk-in Final Rule, DOE 
did not finalize its proposal to require the date of manufacture on the 
nameplate. 81 FR 95758, 95802.
    In this NOPR, DOE is again proposing to require that date of 
manufacture be affixed to each walk-in panel via the nameplate or via 
another method (i.e., stamping) at 10 CFR 431.305(a)(1)(ii). DOE has 
found that date of manufacture is often included on the nameplate or 
stamped elsewhere on walk-in panels, indicating that it is not overly 
burdensome to include and is technologically feasible.
    Additionally, In the May 2023 Walk-Ins TP Final Rule, DOE added 
test provisions for CO2 unit coolers. 88 FR 28780,28809. To 
easily determine which walk-in units these test provisions apply to, 
DOE defined CO2 unit coolers as ``unit coolers that includes 
a nameplate listing only CO2 as an approved refrigerant''. 
88 FR 28780, 28790. Based on walk-in units previously tested by DOE, 
DOE expects that most manufacturers are already including a refrigerant 
indication on the labels of walk-in unit coolers. Additionally, as 
discussed in the May 2023 Walk-ins TP Final Rule, manufacturers 
supported the finalized definition for CO2 unit coolers, 
including the language regarding the nameplates. Id. As such, DOE has 
therefore tentatively concluded that it would not be burdensome for 
manufacturers to label unit coolers designed for use with 
CO2 as a refrigerant. Additionally, DOE has consulted with 
the FTC, and they had no comments on the proposal. Therefore, in this 
NOPR, DOE is proposing that unit coolers designed to be used with 
CO2 as a refrigerant include the statement ``Only 
CO2 is approved as a refrigerant for this system'' on the 
unit nameplate.
    DOE requests comment on its proposal to require that date of 
manufacture be included on a panel nameplate, including its tentative 
conclusion that this would be technologically feasible and would not be 
burdensome to include. DOE also requests comment on its proposal to 
require CO2 unit coolers be labeled with the statement 
``Only CO2 is approved as a refrigerant for this system'', 
including its tentative conclusion that this would not be burdensome to 
include.
4. Labeling Costs and Impact
    Labelling requirements for panels are codified at 10 CFR 
431.305(a). Since manufacturers are already required to apply a 
permanent nameplate to walk-in panels, DOE is assuming that there would 
be no additional cost to the nameplate material or nameplate 
application if DOE were to finalize its proposal to include date of 
manufacturer on the panel nameplate. However, DOE recognizes that 
manufacturers may need to make changes to panel nameplates to include 
date of manufacture.
    DOE is assuming that the date of manufacturer would be 
automatically etched or printed on each nameplate and that there would 
be a one-time cost for programming date of manufacturer into the 
nameplate printing software. DOE estimates that it would take an 
electrical engineer a maximum of 8 hours to configure the nameplate 
printing software. The current fully burdened wage for an electrical 
engineer is $69.97,\23\ resulting in an estimated one-time cost per 
manufacturer of $560 to include date of manufacture on panel 
nameplates.
---------------------------------------------------------------------------

    \23\ DOE estimated the hourly wage using data from BLS's 
``Occupational Employment and Wages, May 2022'' publication. DOE 
used the ``Electrical Engineers'' mean hourly wage of $48.28 to 
estimate the hourly wage rate (www.bls.gov/oes/current/oes172071.htm). DOE then used BLS's ``Employer Costs for Employee 
Compensation--June 2022'' to estimate that wages and salary account 
for approximately 69 percent for private industry workers. 
(www.bls.gov/news.release/pdf/ecec.pdf last accessed on December 1, 
2022). Therefore, DOE estimated a fully burdened labor rate of 
$69.97 ($48.28 / 0.69 = $69.97).
---------------------------------------------------------------------------

    DOE is assuming that the statement ``Only CO2 is 
approved as a refrigerant for this system'' would be automatically 
etched or printed on each nameplate and that there would be a one-time 
cost for programming date of manufacturer into the nameplate printing 
software. DOE estimates that it would take an electrical engineer a 
maximum of 8 hours to configure the nameplate printing software. The 
current fully burdened wage for an electrical engineer is $69.97,\24\ 
resulting in an estimated one-time cost per manufacturer of $560 to 
this statement on CO2 unit cooler nameplates for those 
manufacturers that would need to make this update to their nameplates. 
As previously noted, DOE expects that many manufacturers have already 
done so.
---------------------------------------------------------------------------

    \24\ DOE estimated the hourly wage using data from BLS's

---------------------------------------------------------------------------

N. Commercial and Industrial Pumps

    DOE is proposing to amend the reporting requirements for commercial 
and industrial pumps, which DOE defines as equipment designed to move 
liquids (which may include dissolved gases, free solids, and totally 
dissolved solids) by physical or mechanical action. A pump includes a 
bare pump and, if included by the manufacturer at the time of sale, 
mechanical equipment, driver, and controls. 10 CFR 431.462. DOE is 
proposing amendments to the reporting requirements for commercial and 
industrial pumps in this NOPR.
1. Reporting
    Under the existing requirements in 10 CFR 429.59(b)(2) and (b)(4), 
manufacturers must report the following as determined according to the 
DOE test procedure at appendix A to subpart Y of 10 CFR part 431:
    [cir] For section III: the constant load pump energy index 
(``PEICL''), the nominal speed of rotation in revolutions per minute 
(``rpm''), pump total head in feet at BEP and nominal speed, volume per 
unit time (``flow rate'') in gallons per minute (``gpm'') at BEP and 
nominal speed, calculated driver power input at each load point 
corrected to nominal speed, in horsepower (``hp''), full impeller 
diameter in inches (``in''), and for radially split, multi-stage, 
vertical, in-line diffuser casing (``RSV'') pumps and submersible 
turbine (``ST'') pumps, the number of stages tested. 10 CFR 
429.59(b)(2)(i).
    [cir] For section IV: all the above in addition to whether the 
PEICL is

[[Page 67485]]

calculated or tested. 10 CFR 429.59(b)(2)(ii).
    [cir] For section V: variable load pump energy index (``PEIVL'') 
instead of PEICL, driver power input measured as the input power to the 
driver and controls at each load point corrected to nominal speed, in 
hp, and whether PEIVL is calculated or tested. 10 CFR 
429.59(b)(2)(iii).
    These requirements provide for certifying compliance with the 
standards for commercial and industrial pumps manufactured on or after 
January 27, 2020. Under the existing requirements in 10 CFR 
429.59(b)(3), manufacturers have the option to report pump efficiency 
at BEP in percent and PERCL (for constant load pumps) or 
pump efficiency at BEP in percent and PERVL (for variable 
load pumps), as determined according to appendix A to subpart Y of 10 
CFR part 431.
    In this NOPR, DOE is proposing to require certification of pump 
efficiency at BEP in percent, PERCL, and PERVL--
these metrics would be added to the existing reporting requirements in 
10 CFR 429.59(b)(2). DOE is also proposing that manufacturers would be 
required to comply with the proposed reporting requirement beginning on 
the next certification report annual filing date required for 
commercial and industrial pumps following the publication of this rule, 
if finalized.
    Pump efficiency at BEP, PERCL, and PERVL are 
required for calculating PEICL or PEIVL. Some 
manufacturers are already reporting pump efficiency at BEP, 
PERCL, and/or PERVL, and these metrics are 
already calculated in appendix A to subpart Y of 10 CFR part 431. This 
reporting requirement would standardize the information reported to DOE 
by different pump manufacturers. In addition, having these metrics 
available in DOE's compliance certification database would provide pump 
end users with greater insight into pump operation at part load 
conditions.
    DOE seeks comment on its proposal to require certification of pump 
efficiency at BEP in percent, constant load pump energy rating 
(``PERCL''), and variable load pump energy rating 
(``PERVL'').
2. Reporting Costs and Impacts
    In this NOPR, DOE proposes to amend the reporting requirements for 
commercial and industrial pumps.
    For commercial and industrial pumps subject to the test methods 
prescribed in section III of appendix A to subpart Y of 10 CFR part 
431, manufacturers must currently report the following: (1) 
PEICL; (2) the nominal speed of rotation in rpm; (3) pump 
total head in feet at BEP and nominal speed; (4) volume per unit time 
(flow rate) in gpm at BEP and nominal speed; (5) calculated driver 
power input at each load point i, corrected to nominal speed in hp; (6) 
full impeller diameter in inches; and (6) for RSV and ST pumps, the 
number of stages tested. Manufacturers would additionally report the 
pump efficiency at BEP in percent and PERCL for all pumps if 
the proposed amendments are adopted.
    For pumps subject to the test methods prescribed in section IV or V 
of appendix A to subpart Y of 10 CFR part 431, manufacturers currently 
report the following: (1) PEICL; (2) the nominal speed of 
rotation in rpm; (3) pump total head in feet at BEP and nominal speed; 
(4) volume per unit time (flow rate) in gallons per minute at BEP and 
nominal speed; (5) driver power input at each load point i, corrected 
to nominal speed in hp; (6) full impeller diameter in inches; (7) 
whether the PEICL is calculated or tested; and (8) for RSV 
and ST pumps, the number of stages tested. Manufacturers would 
additionally report pump efficiency at BEP in percent and 
PERCL for all pumps if the proposed amendments are adopted.
    For pumps subject to the test methods prescribed in section VI or 
VII of appendix A to subpart Y of 10 CFR part 431, manufacturers 
currently report the following: (1) PEIVL; (2) the nominal 
speed of rotation in rpm; (3) pump total head in feet at BEP and 
nominal speed; (4) volume per unit time (flow rate) in gpm at BEP and 
nominal speed; (5) driver power input (measured as the input power to 
the driver and controls) at each load point i, corrected to nominal 
speed in hp; (6) full impeller diameter in inches; (7) whether the 
PEIVL is calculated or tested; and (8) for RSH and ST pumps, 
the number of stages tested. Manufacturers would additionally report 
pump efficiency at BEP in percent and PERVL for all pumps if 
the proposed amendments are adopted.
    DOE has tentatively determined that these proposed amendments would 
not impose additional costs for manufacturers because manufacturers of 
commercial and industrial pumps are already submitting certification 
reports to DOE and should have readily available the information that 
DOE is proposing to collect as part of this rulemaking. DOE does not 
believe the revised reporting requirements will cause any appreciable 
change in reporting burden or hours as compared to what commercial and 
industrial pumps manufacturers are currently doing today.
    DOE requests comment on the certification reporting costs of the 
amendments proposed for commercial and industrial pumps.

O. Portable Air Conditioners

    DOE is proposing to amend the reporting requirements for portable 
ACs, which DOE defines as a consumer product that consists of a 
portable encased assembly, other than a ``packaged terminal air 
conditioner,'' ``room air conditioner,'' or ``dehumidifier,'' that 
delivers cooled, conditioned air to an enclosed space, and is powered 
by single-phase electric current. 10 CFR 430.2. In the portable AC test 
procedure final rule published on May 15, 2023 (``May 2023 Portable AC 
Final Rule''), DOE amended the test procedures for portable ACs at 
appendix CC to subpart B of 10 CFR part 430 (``appendix CC'') to 
incorporate a measure of variable-speed portable AC performance and 
make minor clarifying edits. 88 FR 31102. Consistent with that final 
rule, DOE is proposing amendments to the reporting requirements.
1. Reporting
    The current reporting requirements for portable ACs at 10 CFR 
429.62 include the following: (1) the combined energy efficiency ratio 
(``CEER'') in Btu/Wh); (2) the seasonally adjusted cooling capacity 
(``SACC'') in Btu/h; (3) the duct configuration (i.e., single-duct, 
dual-duct, or ability to operate in both configurations); (4) presence 
of heating function; and (5) primary condensate removal feature (i.e., 
auto-evaporation, gravity drain, removable internal collection bucket, 
or condensate pump). 10 CFR 429.62. These requirements provide for 
certifying compliance with the standards that will go into effect for 
single-duct and dual-duct portable ACs that are manufactured on or 
after January 10, 2025. DOE is proposing to update these requirements 
and align the reporting requirements with the recent test procedure 
amendments and is also proposing general certification requirements for 
portable ACs. DOE discusses these proposed updates in the sections as 
follows.
a. Duct-Configuration
    DOE defines two portable AC configurations: single-duct and dual-
duct. Single-duct portable ACs draw all the condenser inlet air from 
the conditioned space without the means of a duct and discharge the 
condenser outlet air outside the conditioned space through a single 
duct attached to an adjustable window bracket. Dual-duct portable ACs 
draw some or all the

[[Page 67486]]

condenser inlet air from outside the conditioned space through a duct 
attached to an adjustable window bracket, may draw additional condenser 
inlet air from the conditioned space, and discharge the condenser 
outlet air outside the conditioned space by means of a separate duct 
attached to an adjustable window bracket. Id.
    The current test procedure for portable ACs, found in appendix CC, 
notes that if a portable AC is able to operate as both a single-duct 
and dual-duct portable AC as distributed in commerce by the 
manufacturer, it must be tested and rated for both duct configurations. 
Section 3.1.1 in appendix CC.
    Similarly, in 10 CFR 429.62(a)(5), DOE states that single-duct and 
dual-duct portable ACs distributed in commerce by the manufacturer with 
multiple duct configuration options that meet DOE's definitions for 
single-duct portable AC and dual-duct portable AC, must be rated and 
certified under both applicable duct configurations.
    Under the existing certification reporting requirements in 10 CFR 
429.62(b)(2), manufacturers of portable ACs must report the following: 
(1) the CEER in Btu/Wh; (2) the SACC in Btu/h; (3) the duct 
configuration (i.e., single-duct, dual-duct, or ability to operate in 
both configurations); (4) presence of heating function; and (5) primary 
condensate removal feature (i.e., auto-evaporation, gravity drain, 
removable internal collection bucket, or condensate pump).
    DOE is proposing to include clarifying amendments to these 
reporting requirements to specify that each certification report must 
include an indication of the duct configuration used for testing (i.e., 
single-duct or dual-duct) and whether the certified model is 
distributed in commerce by the manufacturer with multiple duct 
configuration options that meet DOE's definitions for single-duct 
portable AC and dual-duct portable AC (i.e., yes or no).
    DOE requests comment on the clarifying amendments to 10 CFR 
429.62(b)(2) to better represent the intent of the instruction in 
appendix CC and 10 CFR 429.62(a)(5).
b. Full-Load Seasonally Adjusted Cooling Capacity
    In the May 2023 Portable AC Final Rule, DOE amended the appendix CC 
test procedures to include a new capacity metric for variable-speed 
portable ACs, full-load seasonally adjusted cooling capacity 
(``SACCFull''), for purposes of representation and 
certification. 88 FR 31102, 31112-31114. Consistent with that final 
rule, DOE is proposing to amend the certification report requirements 
by proposing a new section, 10 CFR 429.62(b)(3), to require reporting 
whether a basic model is variable-speed, as defined in appendix CC, and 
if so, to report the SACCFull, in Btu/h.
    DOE seeks comment on requiring whether a basic model is variable-
speed, and if so, to report the SACCFull, in Btu/h.
2. Reporting Costs and Impacts
    In this NOPR, DOE proposes to align portable AC certification 
reporting requirements with the May 2023 Portable AC TP Final Rule 
requirements applicable to portable ACs manufactured on and after the 
June 14, 2023.
    For variable-speed portable ACs tested in accordance with appendix 
CC as amended in the May 2023 Portable AC TP Final Rule, manufacturers 
currently report combined energy efficiency ratio, seasonally adjusted 
cooling capacity, the duct configuration, presence of heating function, 
and primary condensate removal feature, and would additionally report 
full-load seasonally adjusted cooling capacity if the proposed 
amendments are adopted.
    DOE has tentatively determined that these proposed amendments would 
not impose additional costs for manufacturers beyond those that were 
estimated in the January 2020 Portable ACs ECS Final Rule, which first 
established the reporting requirements. 85 FR 1378. This is because 
manufacturers of portable ACs should already be collecting the 
information required for the current certification requirements and 
should have readily available the information that DOE is proposing to 
collect as part of this rulemaking. DOE does not believe the revised 
reporting requirements will cause any appreciable change in reporting 
burden or hours as compared to what was estimated in the January 2020 
Portable ACs ECS Final Rule.
    DOE requests comment on the certification reporting costs of the 
amendments proposed for portable ACs.

P. Compressors

    DOE is proposing to amend the reporting requirements for 
compressors, which DOE defines as machines or apparatuses that convert 
different types of energy into the potential energy of gas pressure for 
displacement and compression of gaseous media to any higher pressure 
values above atmospheric pressure and have a pressure ratio at full-
load operating pressure greater than 1.3. 10 CFR 431.342.
1. Reporting
    Under the existing requirements in 10 CFR 429.63(b), a 
certification report must include the following public product-specific 
information for all compressors: (1) full-load package isentropic 
efficiency or part-load package isentropic efficiency, as applicable 
(dimensionless); (2) full-load actual volume flow rate (in cubic feet 
per minute); (3) compressor motor nominal horsepower (in horsepower); 
(4) full-load operating pressure (in pounds per square inch, gauge); 
(5) maximum full-flow operating pressure (in pounds per square inch, 
gauge); and (6) pressure ratio at full-load operating pressure 
(dimensionless). 10 CFR 429.63(b)(i)-(vi).
    In addition, for any ancillary equipment that is installed for 
test, but is not part of the compressor package as distributed in 
commerce (per the requirements of 10 CFR part 431, subpart T, appendix 
A, section I(B)(4)), a certification report must include the following 
public product-specific information: (1) a general description of the 
ancillary equipment, based on the list provided in the first column of 
Table 1 of 10 CFR part 431, subpart T, appendix A, section I(B)(4); (2) 
the manufacturer of the ancillary equipment; (3) the brand of the 
ancillary equipment (if different from the manufacturer); (4) the model 
number of the ancillary equipment; (5) the serial number of the 
ancillary equipment (if applicable); (6) input voltage (if applicable); 
(7) number of phases (if applicable); (8) input frequency (if 
applicable); (9) size of any connections (if applicable); and (10) type 
of any connections (if applicable). 10 CFR 429.63(b)(vii)(A)-(G). A 
certification report must also include installation instructions for 
the ancillary equipment, accompanied by photos that clearly illustrate 
the ancillary equipment, as installed on compressor package, in a PDF. 
10 CFR 429.63(b)(vii)(H).
    DOE notes that 10 CFR 429.12(a) states that basic models of covered 
products require annual filings on or before the dates provided in 10 
CFR 429.12(d), but paragraph (d) does not specifically list an annual 
filing date for compressors. In light of this omission, DOE proposes to 
explicitly specify in 10 CFR 429.12(d) that compressors should be 
recertified annually on or before September 1. Because the energy 
conservation standards for compressors do not take effect until January 
10, 2025, this annual reporting requirement would not be in effect 
until the

[[Page 67487]]

applicable energy conservation standards are in effect.
    DOE seeks comment on the proposed annual filing date of September 1 
for compressors.
2. Reporting Costs and Impacts
    In this NOPR, DOE proposes no changes to the reported information 
required for compressors when certifying compliance with the standards 
applicable to compressors manufactured on or after January 10, 2025. 
DOE only proposes to specify the annual date by which manufacturers 
must submit annual certification filings to DOE after the applicable 
standards take effect. DOE has tentatively determined that the proposed 
amendment would not impose additional costs for manufacturers because 
no amendments to the certification report contents are being proposed 
in this NOPR. DOE does not believe the revised reporting requirements 
would cause any appreciable change in reporting burden or hours as 
compared to what compressor manufacturers will begin doing prior to the 
January 10, 2025 compliance date.
    DOE requests comment on the proposed annual filing date for 
compressors and any corresponding certification and reporting costs.

Q. Dedicated-Purpose Pool Pump Motors

    DOE is proposing to establish reporting requirements for DPPPMs, 
which are electric motors that are single-phase or polyphase and are 
designed and/or marketed for use in dedicated-purpose pool pump 
(``DPPP'') applications, as defined in sections 1.2, 1.3, and 1.4 of UL 
1004-10:2020. 10 CFR 431.483. In the NOPR published on June 21, 2022 
(``June 2022 DPPPM NOPR''), DOE proposed to establish energy 
conservation standards for DPPPMs. 87 FR 37122. Consistent with that 
notice of proposed rulemaking, DOE is proposing amendments to the 
reporting requirements.
1. Reporting
    There are currently no reporting requirements for DPPPMs. The June 
2022 DPPPM NOPR proposed to establish new energy conservation standards 
for DPPPM. Therefore, DOE is proposing to align the reporting 
requirements with the standards and proposing general certification 
requirements for DPPPM. DOE discusses these proposed updates in the 
sections as follows.
a. Motor Total Horsepower, Full-Load Efficiency, and Design 
Requirements
    In the June 2022 DPPPM NOPR, DOE proposed performance standards 
(i.e., full load efficiency) and design requirements (i.e., speed 
capability) based on DPPPM total horsepower (``THP''). 87 FR 37122, 
37123-37124. DOE proposed that the standards, if adopted, would apply 
to all DPPPMs manufactured in, or imported into, the United States 
starting on the date 2 years (or 24 months) after the publication of 
the final rule for the proposed rulemaking.
    Further, for DPPPMs greater than or equal to 0.5 THP, DOE proposed 
that DPPPMs with freeze protection controls be shipped with the freeze 
protection feature disabled, or with the following default, user-
adjustable settings: (a) the default dry-bulb air temperature setting 
shall be no greater than 40 [deg]F; (b) the default run time setting 
shall be no greater than 1 hour (before the temperature is rechecked); 
and (c) the default motor speed in freeze protection mode shall not be 
more than half of the maximum operating speed. 87 FR 37122, 37124. 
Table III.1 provides the proposed energy conservation standards.

 Table III.1--June 2022 DPPPM NOPR Proposed Energy Conservation Standards for Dedicated Purpose Pool Pump Motors

                                                                                        controls.
1.15 <= THP <= 5.......................  .................  Variable speed control...  Only for DPPP motors with
                                                                                        freeze protection
                                                                                        controls.
----------------------------------------------------------------------------------------------------------------

    As such, in this NOPR, DOE proposes to update the reporting 
requirements to include product-specific information that would be 
required to certify compliance with any newly established energy 
conservation standards. Accordingly, DOE proposes reporting the DPPPM 
THP, as the THP is required to determine whether the DPPPM would need 
to meet either a performance standard or design requirements. DOE 
proposes that the represented value of THP should be determined as 
required at 10 CFR 429.65(c)(1)(v).
    For DPPPMs less than 0.5 THP, DOE proposes reporting the 
performance standard in terms of full load efficiency. DOE proposes 
using the test procedure in 10 CFR 431.484 to determine full-load 
efficiency, and to report the represented value of THP as required at 
10 CFR 429.65(c)(1)(v).
    For DPPPMs greater than or equal to 0.5 THP, DOE proposes reporting 
the design requirements as follows:
    (1) A statement confirming that the DPPPM is variable speed (as 
defined at 10 CFR 431.483); and
    (2) A statement regarding whether freeze protection is shipped 
enabled or disabled; for DPPPMs distributed in commerce with freeze 
protection controls enabled, DOE proposes reporting the default dry-
bulb air temperature setting (in [deg]F), default run time setting (in 
minutes), maximum operating speed (in revolutions per minute, or rpm), 
and default motor speed in freeze protection mode (in revolutions per 
minute, or rpm).
    Regarding general certification requirements, DOE proposes that 
annual filing for DPPPM shall be submitted on or before September 1. 
Further, DOE also proposes that the requirements in 10 CFR 429.12 
regarding certification apply to DPPPMs.
    DOE seeks comment on the proposed reporting requirements for 
DPPPMs.
b. Rounding Requirements
    DOE proposes to specify rounding requirements for values required 
to determine compliance with the proposed energy conservation 
standards. Specifically, DOE proposes that manufacturers round DPPPM 
THP to the nearest hundredth of THP, consistent with industry practice. 
Further, DOE proposes that

[[Page 67488]]

manufacturers round full load efficiency, expressed in percentage, to 
the nearest tenth of a percent. This is consistent with how the full 
load efficiency of an electric motor is expressed at 10 CFR 431.25 and 
10 CFR 431.446, and these electric motors share test methods with 
DPPPMs. Finally, for DPPPM basic models with THPs greater than or equal 
to 0.5 THP and distributed in commerce with freeze protection controls 
enabled, DOE proposes to round the dry-bulb temperature setting 
(expressed in [deg]F) run time setting (expressed in minutes), maximum 
operating speed (expressed in rpm), and default motor speed in freeze 
protection mode (expressed in rpm) to the nearest whole number. This is 
consistent with how dry-bulb temperature is expressed in 10 CFR 
431.465(h)(1).
    DOE seeks comment on the proposed rounding requirements for DPPPMs.
2. Reporting Costs and Impacts
    In this NOPR, DOE proposes to align DPPPM certification reporting 
requirements with the proposed energy conservation standard 
requirements applicable to DPPPMs manufactured starting on the date 2 
years (24 months) after the date of final rule publication of the 
energy conservation standard in the Federal Register.
    The addition of the proposed reporting requirements for DPPPMs 
would newly require manufacturers to report performance characteristics 
of these motors. For DPPPMs less than 0.5 THP, full-load efficiency 
would need to be reported in addition to THP, and for DPPPMs greater 
than or equal to 0.5 THP, freeze protection status and speed control 
capability would need to be reported in addition to THP. DOE has 
tentatively concluded that these proposed changes would impose 
additional cost to manufacturers and importers. The costs associated 
with these changes are described in further detail in section IV.C of 
this document.
    DOE requests comment on the certification reporting costs of the 
proposed new reporting requirements for DPPPMs.

R. Air Cleaners

    DOE is proposing to establish reporting requirements for air 
cleaners, which DOE defines as a product for improving indoor air 
quality, other than a central air conditioner, room air conditioner, 
portable air conditioner, dehumidifier, or furnace, that is an 
electrically-powered, self-contained, mechanically encased assembly 
that contains means to remove, destroy, or deactivate particulates, 
VOCs, and/or microorganisms from the air. It excludes products that 
operate solely by means of ultraviolet light without a fan for air 
circulation. 10 CFR 430.2. In a direct final rule published on April 
11, 2023 (``April 2023 Air Cleaners DFR''), DOE established new energy 
conservation standards for air cleaners. 88 FR 21752. Consistent with 
that direct final rule, DOE is proposing to establish new reporting 
requirements for air cleaners.
1. Reporting
    There are currently no reporting requirements for air cleaners. The 
April 2023 Air Cleaners DFR established new energy conservation 
standards for air cleaners. 88 FR 21752. In the April 2023 Air Cleaners 
DFR, DOE established energy conservation standards based on integrated 
energy factor (``IEF''), which is determined as the clean air delivery 
rate (``CADR'') \25\ of an air cleaner expressed in terms of 
PM2.5 \26\ CADR divided by the annual energy consumption 
divided by the annual active mode hours. 88 FR 21752, 27153-21754. 
PM2.5 CADR is calculated as the geometric mean of smoke CADR 
and dust CADR. 88 FR 21752, 21762.
---------------------------------------------------------------------------

    \25\ Section 3.14 of the industry standard AHAM AC-1-2020 
defines CADR as the measure of the delivery of contaminant free air, 
within a defined particle size range, by an air cleaner, expressed 
in cubic feet per minute (``cfm''). CADR is the rate of contaminant 
reduction in the test chamber when the air cleaner is turned on, 
minus the rate of natural decay when the air cleaner is not running, 
multiplied by the volume of the test chamber as measured in cubic 
feet. Note: CADR values are always the measurement of an air cleaner 
performance as a complete system and have no linear relationship to 
the air movement per se or to the characteristics of any particle 
removal methodology.
    \26\ 10 CFR part 430, appendix FF defines PM2.5 via 
reference to the industry standard AHAM AC-7-2022, which defines it 
as particulate matter that are nominally 2.5 micrometers (``[mu]m'') 
in width or smaller.
---------------------------------------------------------------------------

    Therefore, DOE is proposing to align the reporting requirements 
with the standards and proposing general certification requirements for 
air cleaners. DOE discusses these proposed updates in the following 
paragraphs.
    DOE proposes to establish reporting requirements for air cleaners 
at 10 CFR 429.68(b) to include product-specific information that would 
be required to certify compliance with the newly established energy 
conservation standards. DOE proposes that parties must report the smoke 
CADR, dust CADR, and PM2.5 CADR in cfm; annual energy 
consumption in kWh/yr; and, IEF in PM2.5 CADR per watt. DOE 
is proposing reporting requirements for smoke CADR and dust CADR 
because these values are used to determine PM2.5 CADR.
    Additionally, in a test procedure final rule published on March 6, 
2023 (March 2023 Air Cleaners TP Final Rule), DOE established 
requirements for determining pollen CADR and effective room size. 88 FR 
14014, 14016. In the March 2023 Air Cleaners TP Final Rule, DOE noted 
that many air cleaners are marketed as providing pollen removal and the 
ENERGY STAR specification for air cleaners also requires reporting of 
pollen CADR. DOE stated that it is important that any representation 
related to an air cleaner's pollen CADR performance be made based on 
testing conducted in a repeatable and representative manner. 88 FR 
14014, 14034. Accordingly, in the March 2023 Air Cleaners TP Final 
Rule, DOE referenced the AHAM AC-1-2020 standard to conduct a test to 
measure pollen CADR. 88 FR 14014, 14035. While DOE has not established 
any energy conservation standards for pollen, DOE is proposing to 
include a reporting requirement for pollen CADR in this NOPR to ensure 
that consumers have reliable information when making purchasing 
decisions.
    Additionally, in the March 2023 Air Cleaners TP Final Rule, DOE 
established a metric for effective room size because room size would 
strongly impact the capacity of the air cleaner that would be required 
to clean the air in the desired room. 88 FR 14014, 14036 and 14038. 
While DOE has not established any standards pertaining to room size, 
DOE is proposing to include a reporting requirement for effective room 
size, in square feet, to ensure consumers have reliable information 
when making purchasing decisions.
    Regarding general certification requirements, DOE proposes that the 
annual filing for air cleaners shall be submitted on or before December 
1. Further, DOE also proposes that the requirements in 10 CFR 429.12 
regarding certification apply to air cleaners. Finally, DOE proposes to 
add a new paragraph (i)(6) in 10 CFR 429.12 to note the compliance date 
for air cleaners is December 31, 2023.
    DOE requests comment on the proposed reporting requirements for air 
cleaners.
2. Reporting Costs and Impacts
    In this NOPR, DOE proposes to align air cleaner certification 
reporting requirements with the energy conservation standard 
requirements established in the April 2023 Air Cleaners DFR, such that 
the reporting requirements are applicable to air cleaners manufactured 
on and after December 31, 2023.
    The addition of the proposed reporting requirements for air 
cleaners would newly require manufacturers to

[[Page 67489]]

report this information. DOE has tentatively concluded that these 
proposed reporting requirements would impose additional cost to 
manufacturers and importers. The costs associated with these changes 
are described in further detail in section IV.C of this document.
    DOE requests comment on the certification reporting costs of the 
proposed new reporting requirements for air cleaners.

S. Single Package Vertical Units

    DOE is proposing to amend the reporting requirements for single 
package vertical air conditioners (``SPVACs'') and single package 
vertical heat pumps (``SPVHPs''), collectively referred to as ``single 
package vertical units'' (``SPVUs'').
    DOE defines an SPVAC as air-cooled commercial package air 
conditioning and heating equipment that: (1) is factory-assembled as a 
single package that: (i) has major components that are arranged 
vertically; (ii) is an encased combination of cooling and optional 
heating components; and (iii) is intended for exterior mounting on, 
adjacent interior to, or through an outside wall; (2) is powered by a 
single-phase or three-phase current; (3) may contain one or more 
separate indoor grilles, outdoor louvers, various ventilation options, 
indoor free air discharges, ductwork, well plenum, or sleeves; and (4) 
has heating components that may include electrical resistance, steam, 
hot water, or gas, but may not include reverse cycle refrigeration as a 
heating means. 10 CFR 431.92. Additionally, DOE defines an SPVHP as a 
single package vertical air conditioner that: (1) uses reverse cycle 
refrigeration as its primary heat source; and (2) may include secondary 
supplemental heating by means of electrical resistance, steam, hot 
water, or gas. Id.
    In a test procedure final rule published in the Federal Register on 
December 7, 2022 (``December 2022 SPVU TP final rule''), DOE added 
definitions for ``single-phase single package vertical air conditioner 
with cooling capacity less than 65,000 Btu/h'' and ``single-phase 
single package vertical heat pump with cooling capacity less than 
65,000 Btu/h.'' 87 FR 75144, 75167-75168; 10 CFR 431.92. DOE defines 
this equipment as SPVAC and SPVHP that are either: (1) weatherized, or 
(2) non-weatherized and have optional ventilation air provisions 
available with the ability to draw in and condition a minimum of 400 
CFM of outdoor air, as determined in accordance with 10 CFR 
429.134(x)(3), while the equipment is operating with the same drive kit 
and motor settings used to determine the certified efficiency rating of 
the equipment. Id.
    The Federal test procedures are applicable to SPVUs with a cooling 
capacity less than 760,000 Btu/h. (42 U.S.C. 6311(8)(D)(ii)) In the 
December 2022 SPVU TP final rule, DOE incorporated by reference AHRI 
390-2021 which maintains the existing efficiency metrics--energy 
efficiency ratio (``EER'') for cooling mode and coefficient of 
performance (``COP'') for heating mode--but it also added a seasonal 
efficiency metric that includes part-load cooling performance--
integrated energy efficiency ratio (``IEER''). 87 FR 75144, 75167-75170 
(Dec. 7, 2022). In an energy conservation standards NOPR published in 
the Federal Register on December 8, 2022 (``December 2022 SPVU ECS 
NOPR''), DOE proposed to amend the energy conservation standards for 
SPVUs to be based on the IEER metric for cooling efficiency (while 
retaining the COP metric for determining the heating efficiency of 
SPVHPs). 87 FR 75388, 75421. Consistent with the December 2022 SPVU TP 
final rule and the December 2022 SPVU ECS NOPR, DOE is proposing 
amendments to the reporting requirements for SPVUs that would be 
utilized with energy conservation standards denominated in terms of 
IEER, should DOE adopt such standards.
1. Reporting
    Under the existing requirements for SPVACs and SPVHPs in 10 CFR 
429.43(b)(2)(v) and 10 CFR 429.43(b)(2)(vi), respectively, 
manufacturers must report the following information for SPVACs and 
SPVHPs: the energy efficiency ratio (EER in British thermal units per 
Watt-hour (Btu/Wh)) and the rated cooling capacity in British thermal 
units per hour (Btu/h). For SPVHPs, manufacturers must additionally 
report the coefficient of performance (COP).
    These requirements provide for certifying compliance with the 
applicable standards for SPVUs manufactured on and after September 23, 
2019 for units with cooling capacity <65,000 Btu/h, on and after 
October 9, 2015 for units >=65,000 Btu/h and <135,000 Btu/h, and on and 
after October 9, 2016 for units >=135,000 Btu/h and <240,000 Btu/h. 
These energy conservation standards for SPVUs are codified in DOE's 
regulations at 10 CFR 431.97(d)(3). DOE is proposing to update these 
requirements and align the reporting requirements with the amended 
energy conservation standards proposed in the December 2022 SPVU ECS 
NOPR. DOE discusses these proposed updates in the sections as follows.
a. Revising Certification Reporting Requirements at 10 CFR 
429.43(b)(2)(v) and 10 CFR 429.43(b)(2)(vi) When Certifying SPVUs of 
All Rated Capacities With IEER Standards
    SPVU manufacturers are currently required to certify compliance 
with EER and, for SPVHPs, also COP standards, in addition to the other 
reported items mentioned previously. In this NOPR, DOE is proposing 
certification requirements when certifying compliance of SPVUs of all 
rated capacities with IEER standards, should such standards be adopted. 
Specifically, DOE proposes to include the following at 10 CFR 
429.43(b)(2)(v)(B) and (b)(2)(vi)(B) when certifying compliance an IEER 
standard: the integrated energy efficiency ratio (IEER in British 
thermal units per Watt-hour (Btu/Wh)), the rated cooling capacity in 
British thermal units per hour (Btu/h), and the rated airflow in 
standard cubic feet per minute (SCFM). Additionally, DOE proposes to 
include a requirement to certify the coefficient of performance (COP) 
for SPVHPs at 10 CFR 429.43(b)(2)(vi)(B). DOE also proposes to move the 
existing text in 10 CFR 429.43(b)(2)(v) and 10 CFR 429.43(b)(2)(vi) to 
10 CFR 429.43(b)(2)(v)(A) and 10 CFR 429.43(b)(2)(vi)(A), respectively.
    DOE seeks comment on its proposed certification requirements for 
SPVUs of all rated capacities when certifying compliance with IEER 
standards.
b. Additional Certification Reporting Requirements for SPVUs With a 
Cooling Capacity <65,000 Btu/h
    As discussed previously, DOE added definitions at 10 CFR 431.92 for 
single-phase SPVACs and SPVHPs with a cooling capacity less than 65,000 
Btu/h. For non-weatherized equipment, the definition requires these 
SPVUs to have the capability to draw in and condition up to 400 CFM of 
outdoor air. The method for determining this outdoor ventilation 
airflow rate is provided at 10 CFR 429.134(x)(3). DOE is proposing to 
require single-phase SPVAC and SPVHP with cooling capacity less than 
65,000 Btu/h to report whether the unit is weatherized or non-
weatherized, and if non-weatherized, the amount of outdoor air which it 
is capable of drawing in and conditioning while the equipment is 
operating with the same drive kit and motor settings used to determine 
its certified efficiency rating. These requirements will apply when 
certifying compliance with energy conservation

[[Page 67490]]

standards denominated in terms of IEER, should DOE adopt such 
standards.
    DOE seeks comment on its proposed additional certification 
requirements for SPVUs with a cooling capacity less than 65,000 Btu/h.
c. Updating Supplemental Testing Instructions for SPVACs and SPVHPs
    Manufacturers are currently required to submit Supplemental Testing 
Instructions (``STIs'') regarding: additional test instructions if 
applicable; if a variety of motors/drive kits are offered for sale as 
options in the basic model to account for varying installation 
requirements, the model number and specifications of the motor (to 
include efficiency, horsepower, open/closed, and number of poles) and 
the drive kit, including settings, associated with that specific motor 
that were used to determine the certified rating; and which, if any, 
special features were included in rating the basic model. 10 CFR 
429.43(b)(4)(vi) and (b)(4)(vii). DOE proposes to further specify the 
information manufacturers must report in their STIs that would enable 
the independent conduct a test of the relevant equipment to the updated 
test procedure in terms of IEER, including requirements to report 
compressor break-in period and outdoor air-side attachments, and to 
align with corresponding requirements for CUACs, where appropriate.
    In all, DOE proposes to maintain the current requirements of 10 CFR 
429.43(b)(4)(vi) and (b)(4)(vii), but move them to 10 CFR 
429.43(b)(4)(vi)(A) and (b)(4)(vii)(A) respectively for EER 
certification. DOE proposes to add new provisions for SPVACs and SPVHPs 
in 10 CFR 429.43(b)(4)(vi)(B) and (b)(4)(vii)(B) for IEER certification 
to require: Compressor break-in period duration; rated indoor airflow 
in standard cubic feet per minute (SCFM); frequency or control set 
points, including the required dip switch/control settings for step or 
variable speed components (e.g., compressors, VFDs); rated indoor 
airflow in SCFM for each part-load point used in the IEER calculation 
and any special instructions required to obtain operation at each part-
load point, such as frequency or control set points including dip 
switch/control settings for step or variable speed components (e.g., 
compressors, VFDs); a statement whether the model will operate at test 
conditions without manufacturer programming; any additional testing 
instructions, if applicable; and if a variety of motors/drive kits are 
offered for sale as options in the basic model to account for varying 
installation requirements, the model number and specifications of the 
motor (to include efficiency, horsepower, open/closed, and number of 
poles) and the drive kit, including settings, associated with that 
specific motor that were used to determine the certified rating; 
outdoor air-side attachments used for testing, or any additional 
applicable testing instructions, are also required. Additionally, for 
SPVHPs, DOE proposes to add a requirement in 10 CFR 
429.43(b)(4)(vii)(B) for the rated airflow in SCFM in heating mode if 
the unit is designed to operate with different airflow rates for 
cooling and heating mode.
    The proposed certification requirements provide further direction 
to the existing requirements and would not result in significant 
additional burden for manufacturers. Where DOE identifies specific 
test-related information, the relevant information is already collected 
by or available to the manufacturer, and that as such, reporting that 
information to DOE would result in minimal additional burden.
    DOE seeks comment on its proposed supplemental testing instructions 
requirements for SPVUs when certifying compliance with IEER standards, 
should such standards be adopted.
d. AEDM Tolerance for IEER
    DOE's existing testing regulations allow the use of an AEDM, in 
lieu of testing, to simulate the efficiency of SPVUs. 10 CFR 429.43(a). 
For models certified with an AEDM, results from DOE verification tests 
are subject to certain tolerances when compared to certified ratings. 
Currently, DOE specifies a 5-percent tolerance for SPVUs verification 
tests for both EER and COP, identical to the current tolerance 
specified for these single-point metrics for other categories of 
commercial air conditioners and heat pumps. See table 2 to paragraph 
(c)(5)(vi)(B) at 10 CFR 429.70. For integrated seasonal metrics (i.e., 
IEER) for other categories of commercial air conditioners and heat 
pumps, DOE specifies a 10-percent tolerance. See Id. In alignment with 
such tolerances, DOE is proposing to specify a 10-percent tolerance for 
IEER for SPVUs.
    DOE seeks comment on its proposal to specify a tolerance of 10 
percent for SPVU verification tests for IEER.
2. Reporting Costs and Impacts
    In this NOPR, DOE proposes to align SPVU certification reporting 
requirements with the amended energy conservation standards proposed in 
the December 2022 SPVU ECS NOPR.
    DOE has tentatively determined that these proposed amendments would 
not impose additional costs for manufacturers, because manufacturers of 
SPVUs are already submitting certification reports to DOE and should 
have readily available the information that DOE is proposing to collect 
as part of this rulemaking. DOE does not believe the revised reporting 
requirements will cause any appreciable change in reporting burden or 
hours as compared to what SPVU manufacturers are currently doing.
    DOE requests comment on the certification reporting costs of the 
amendments proposed for SPVUs.

T. Ceiling Fan Light Kits

    DOE is proposing to amend the reporting requirements for CFLKs, 
which DOE defines as equipment designed to provide light from a ceiling 
fan that can be (1) integral, such that the equipment is attached to 
the ceiling fan prior to the time of retail sale; or (2) attachable, 
such that at the time of retail sale the equipment is not physically 
attached to the ceiling fan, but may be included inside the ceiling fan 
at the time of sale or sold separately for subsequent attachment to the 
fan. 10 CFR 430.2.
1. Reporting
    In 10 CFR 429.33(b)(2)(ii)(A) and (b)(3)(ii)(B), DOE specifies 
information that must be included in the certification report for each 
basic model of CFLK manufactured on or after January 21, 2020. These 
paragraphs specify these requirements for ``for each basic model of 
lamp and/or each basic model of non-consumer-replaceable SSL packaged 
with the ceiling fan light kit.'' On April 10, 2023, DOE published a 
final rule amending CFLK test procedures. 88 FR 21061 (``April 2023 
CFLK TP Final Rule''). In this rule, to clarify terminology used in the 
test procedure, DOE replaced the terms ``other SSL products'' and 
``integrated SSL circuitry'' with, respectively, ``consumer-replaceable 
SSL'' and ``non-consumer-replaceable SSL'' in the CFLK test procedure 
appendix, 10 CFR 429.33, 10 CFR 430.23(x), and 10 CFR 430.32(s)(6). 88 
FR 21061, 21067-21068. Because 10 CFR 429.33(b)(2)(ii)(A) and 
(b)(3)(ii)(B) only specified ``integrated SSL circuitry'' and omitted 
``other SSL products,'' the April 2023 CFLK TP Final Rule only replaced 
``integrated SSL circuitry'' with ``non-consumer-replaceable SSL'' and 
did not include ``consumer replaceable SSL'', the replacement term for 
``other SSL products.'' 88 FR 21061, 21072. Hence, CFLKs packaged with 
consumer-

[[Page 67491]]

replaceable SSL are inadvertently omitted from this language. DOE is 
proposing modify this language to include them and read as follows, 
``for each basic model of lamp, each basic model of consumer-
replaceable SSL, and/or each basic model of non-consumer-replaceable 
SSL packaged with the ceiling fan light kit''. This proposed 
modification to 10 CFR 429.33(b)(2)(ii)(A) and (b)(3)(ii)(B) will 
ensure that all types of CFLKs are explicitly included in certification 
requirements.
    DOE requests comment on the proposed correction to existing CFLK 
certification requirements.
2. Reporting Costs and Impacts
    In this NOPR, DOE proposes to correct the existing certification 
reporting requirements for CFLKs manufactured on or after January 21, 
2020.
    DOE has tentatively determined that these proposed amendments would 
not impose additional costs for manufacturers because manufacturers of 
CFLKs are already submitting certification reports to DOE and should 
have readily available the information that DOE is proposing to collect 
as part of this rulemaking. DOE does not believe the revised reporting 
requirements will cause any appreciable change in reporting burden or 
hours as compared to what CFLK manufacturers are currently doing today.
    DOE requests comment on the certification reporting costs of the 
amendments proposed for CFLKs.

U. Additional Corrections

    10 CFR 429.12(i) includes the compliance dates for certain 
products. Specifically, the instructions state that for any product 
subject to an applicable energy conservation standard for which the 
compliance date has not yet occurred, the manufacturer must submit a 
certification report no later than the compliance date for the 
applicable energy conservation standard. However, for the covered 
products currently listed in 10 CFR 429.12(i), the compliance dates for 
initial certification have already occurred. Accordingly, DOE proposes 
to remove the covered products and associated compliance dates in 10 
CFR 429.12(i)(1)-(5). DOE also proposes to add three new paragraphs at 
10 CFR 429.12(i)(1)-(3) for air cleaners, DPPPMs, and DX-DOASes. 
Initial certification would be required by December 31st, 2023 for air 
cleaners and May 1st, 2024 for DX-DOASes. For DPPPMs, initial 
certification would be required 24 months after date of publication of 
a final rule amending DPPPM standards.
    DOE provides definitions related to the energy efficiency program 
for certain commercial and industrial equipment in 10 CFR 431.2. In 
this section, DOE has identified updates needed in two definitions. The 
definition for ``covered equipment'' lists covered equipment and notes 
where the covered equipment term is defined within 10 CFR. ``Commercial 
heating, ventilating, and air conditioning, and water heating product 
(HVAC & WH product)'' are included in this list and refers to this term 
as defined in Sec.  431.172. However, this term is defined in 10 CFR 
431.2, rather than Sec.  431.172. As such, DOE is proposing to update 
the definition for ``covered equipment'' to update the reference to the 
definition for ``commercial heating, ventilating, and air conditioning, 
and water heating product'' in 10 CFR 431.2.
    Additionally, as mentioned above, the definition of ``covered 
equipment'' in 10 CFR 431.2 is intended to reference each equipment 
type covered within 10 CFR part 431. The current definition does not 
include all covered equipment types. Therefore, DOE is proposing to add 
these equipment types and their corresponding definition section 
references within the definition of covered equipment in 10 CFR 431.2. 
Specifically, DOE proposes to add references to: fan or blower, as 
defined in Sec.  431.172; compressor, as defined in Sec.  431.342; 
small electric motor, as defined in Sec.  431.442; pump, as defined in 
Sec.  431.462; and dedicated purpose pool pump motor, as defined in 
Sec.  431.483.
    DOE requests comment on the proposed updates to compliance dates 
listed in 10 CFR 429.12 and to the ``covered equipment'' definition in 
10 CFR 431.2.

V. Draft Certification Templates for Review

    To help interested parties better understand and review the 
proposed amendments discussed in the earlier sections of this NOPR, DOE 
has developed a draft document that includes example tables showing the 
certification report template inputs as would be required in accordance 
with the proposals in this NOPR, if finalized.\27\ The draft tables 
also include the data entry requirements for each field in the 
certification report input table.
---------------------------------------------------------------------------

    \27\ The draft reporting template requirements will be made 
available in docket number EERE-2023-BT-CE-0001, available at 
www.regulations.gov, upon publication of this NOPR.
_____________________________________-

    The draft certification table headers are not reflective of the 
final certification regulations that may be adopted by a subsequent 
final rule, nor do they represent the entirety of the information 
required in a certification report. Upon completion of this rulemaking, 
DOE will revise the reporting templates to reflect the final 
certification regulations once DOE has received approval from OMB to 
collect the revised information. The specific templates that should be 
used for certifying compliance of covered products and equipment to DOE 
are available for download at www.regulations.doe.gov/ccms/templates.

IV. Procedural Issues and Regulatory Review

A. Review Under Executive Orders 12866, 13563, and 14094

    Executive Order (``E.O.'') 12866, ``Regulatory Planning and 
Review,'' as supplemented and reaffirmed by E.O. 13563, ``Improving 
Regulation and Regulatory Review,'' 76 FR 3821 (Jan. 21, 2011), and 
amended by E.O. 14094, ``Modernizing Regulatory Review,'' 88 FR 21879 
(April 11, 2023), requires agencies, to the extent permitted by law, to 
(1) propose or adopt a regulation only upon a reasoned determination 
that its benefits justify its costs (recognizing that some benefits and 
costs are difficult to quantify); (2) tailor regulations to impose the 
least burden on society, consistent with obtaining regulatory 
objectives, taking into account, among other things, and to the extent 
practicable, the costs of cumulative regulations; (3) select, in 
choosing among alternative regulatory approaches, those approaches that 
maximize net benefits (including potential economic, environmental, 
public health and safety, and other advantages; distributive impacts; 
and equity); (4) to the extent feasible, specify performance 
objectives, rather than specifying the behavior or manner of compliance 
that regulated entities must adopt; and (5) identify and assess 
available alternatives to direct regulation, including providing 
economic incentives to encourage the desired behavior, such as user 
fees or marketable permits, or providing information upon which choices 
can be made by the public. DOE emphasizes as well that E.O. 13563 
requires agencies to use the best available techniques to quantify 
anticipated present and future benefits and costs as accurately as 
possible. In its guidance, the Office of Information and Regulatory 
Affairs (``OIRA'') in the Office of Management

[[Page 67492]]

and Budget (``OMB'') has emphasized that such techniques may include 
identifying changing future compliance costs that might result from 
technological innovation or anticipated behavioral changes. For the 
reasons stated in the preamble, this proposed regulatory action is 
consistent with these principles.
    Section 6(a) of E.O. 12866 also requires agencies to submit 
``significant regulatory actions'' to OIRA for review. This action does 
not constitute a significant action under section 3(f) of E.O. 12866. 
Accordingly, this action was not submitted to OIRA for review under 
E.O. 12866.

B. 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'') 
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 Executive Order 13272, ``Proper Consideration of Small 
Entities in Agency Rulemaking,'' 67 FR 53461 (August 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 DOE 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 
reviewed this proposed rule under the provisions of the Regulatory 
Flexibility Act and the procedures and policies published on February 
19, 2003.
    DOE has tentatively concluded that the removal of outdated 
reporting requirements and the addition of new reporting requirements 
adopted in this final rule will not impose additional costs for 
manufacturers of CAC/HPs, DWs, RCWs, dehumidifiers, EPSs, battery 
chargers, CRACs, three-phase, less than 65,000 Btu/h ACUACs and ACUHPs, 
three-phase, less than 65,000 Btu/h VRF, ACIMs, walk-ins, commercial 
and industrial pumps, portable ACs, compressors, SPVUs, and CFLKs for 
the reasons discussed in section III of this document. For these 
products and equipment, DOE has determined that the amendments will not 
impose additional costs for manufacturers because manufacturers are 
already submitting certification reports to DOE and should have readily 
available the information that DOE is requiring as part of this 
proposed rulemaking. Consequently, for these types of covered products 
and equipment, the changes in this proposed rule are not expected to 
have a significant economic impact on related entities regardless of 
size.
    For electric pool heaters, no certification is currently required. 
This proposal would add reporting requirements to align with the 
amended energy conservation standards finalized in the May 2023 Pool 
Heaters Final Rule, which established new and amended energy 
conservation standards for electric pool heaters. 88 FR 34624. 
Therefore, electric pool heater manufacturers would incur additional 
paperwork costs.
    Consumer pool heaters are classified under NAICS code 333414, 
``heating equipment (except warm air furnaces) manufacturing.'' The SBA 
sets a threshold of 500 employees or fewer for an entity to be 
considered as a small business for this category. DOE used publicly 
available information to identify potential small manufacturers. DOE's 
research involved industry trade association membership directories 
(e.g., AHRI), information from previous rulemakings, individual company 
websites, and market research tools (e.g., D&B Hoovers reports) to 
create a list of companies that manufacture consumer pool heaters. DOE 
also asked stakeholders and industry representatives if they were aware 
of any additional small manufacturers during manufacturer interviews. 
DOE reviewed publicly available data and contacted various companies on 
its complete list of manufacturers to determine whether they met the 
SBA's definition of a small business manufacturer. DOE screened out 
companies that do not offer products impacted by this rulemaking, do 
not meet the definition of a ``small business,'' or are foreign-owned 
and operated. DOE identified 21 companies manufacturing consumer pool 
heaters covered by this proposed rulemaking. Of these manufacturers, 
DOE identified six as domestic small businesses. None of these six 
businesses manufacture gas fired pool heaters. Five manufacture 
electric heat pump pool heaters and one manufactures electric 
resistance pool heaters. DOE estimates that the increased certification 
burden would result in 35 hours per manufacturer to develop the 
required certification reports. Therefore, based on a fully burdened 
labor rate of $67 per hour, the estimated total annual cost to 
manufacturers would be $2,345 per manufacturer.\28\ Using available 
public information, DOE estimated the average annual revenue of the six 
small businesses. Among the small businesses, the lowest estimated 
annual revenue was approximately $259,000--therefore, this additional 
certification cost of $2,345 per manufacturer represents less than 1 
percent of the identified manufacturer's annual revenue.

---------------------------------------------------------------------------

    Additionally, for DX-DOASes, no certification is currently 
required. This proposal would add reporting requirements to align with 
the new energy conservation standards. 10 CFR 431.97(g). Therefore, DX-
DOASes manufacturers would incur additional paperwork costs as well. 
DX-DOASes are classified under NAICS code 333415,\29\ ``Air-
Conditioning and Warm Air Heating Equipment and Commercial and 
Industrial Refrigeration Equipment 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. In reviewing the DX-DOAS market, 
DOE used company websites, marketing research tools, product 
catalogues, and other public information to identify companies that 
manufacture DX-DOASes. DOE screened out companies that do not meet the 
definition of ``small business'' or are foreign-owned and operated. DOE 
used subscription-based business information tools to determine 
headcount, revenue, and geographic presence of the small businesses. 
DOE identified twelve companies manufacturing DX-DOASes covered by this 
rulemaking. Of these manufacturers, DOE identified one as a domestic 
small business. DOE estimates that the increased certification burden 
would result in 35 hours per manufacturer to develop the required 
certification reports. Therefore, based on a fully burdened labor rate 
of $67 per hour, the estimated total annual cost to manufacturers would 
be $2,345 per manufacturer.\30\ DOE understands the annual revenue of 
the small business

[[Page 67493]]

that manufactures DX-DOASes to be approximately $66 million. 87 FR 
5560, 5584. Therefore, this additional certification cost of $2,345 per 
manufacturer represents significantly less than 1 percent of the 
identified manufacturer's annual revenue.

---------------------------------------------------------------------------

    This document also proposes certification reporting requirements 
for commercial electric instantaneous water heaters, which would align 
with the previously inadvertently omitted energy conservation standards 
put in place by EPCA and were proposed in the May 2022 CWH NOPR. 87 FR 
30610. As a result, commercial electric instantaneous water heater 
manufacturers would incur additional paperwork costs. CWH equipment is 
classified under NAICS code 333310,\31\ ``Commercial and Service 
Industry Machinery Manufacturing.'' In 13 CFR 121.201, the SBA sets a 
threshold of 1,000 employees or fewer for an entity to be considered as 
a small business for this category. DOE's analysis relied on publicly 
available databases to identify potential small businesses that 
manufacture equipment covered in this rulemaking. DOE utilized the 
California Energy Commission's MAEDbS,'' \32\ DOE's ENERGY STAR 
Database,\33\ and DOE's CCD \34\ in identifying manufacturers. DOE's 
research identified nine original equipment manufacturers (``OEMs'') of 
commercial electric instantaneous water heaters being sold in the U.S. 
market. Of these nine companies, DOE has identified three as domestic 
small businesses. The small businesses do not currently certify any 
other CWH equipment to DOE's Compliance Certification Management System 
(``CCMS''). DOE estimates that the increased certification burden would 
result in 35 hours per manufacturer to develop the required 
certification reports. Therefore, based on a fully burdened labor rate 
of $67 per hour, the estimated total annual cost to manufacturers would 
be $2,345 per manufacturer.\35\ Using available public information, DOE 
estimated the annual revenue for all three small businesses that 
manufacture commercial electric instantaneous water heaters. The small 
business with the least annual revenue has an annual revenue of 
approximately $10,400,000. Therefore, this additional certification 
cost of $2,345 per manufacturer represents significantly less than 1 
percent of each identified manufacturer's annual revenue.

---------------------------------------------------------------------------

    For DPPPMs, no certification is currently required. This proposal 
would add reporting requirements to align with the energy conservation 
standards proposed in the June 2022 DPPPM NOPR, which proposed new 
energy conservation standards for DPPPMs. 87 FR 37122. Therefore, DPPPM 
manufacturers would incur additional paperwork costs. DPPPMs are 
classified under NAICS code 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 in this category. 
DOE screened out companies that do not offer products impacted by this 
rulemaking, do not meet the definition of a ``small business,'' or are 
foreign-owned and operated. DOE identified five companies manufacturing 
DPPPMs for the domestic market. Of those, DOE determined that one 
company met the SBA definition of a small business. DOE estimates that 
the increased certification burden would result in 35 hours per 
manufacturer to develop the required certification reports annually. 
Therefore, based on a fully burdened labor rate of $67 per hour, the 
estimated total annual cost to manufacturers would be $2,345 per 
manufacturer.\36\ DOE was able to identify an annual revenue estimate 
of approximately $28.2 million for the small business.\37\ Therefore, 
this additional certification cost of $2,345 per manufacturer 
represents significantly less than 1 percent of the identified 
manufacturer's annual revenue.

---------------------------------------------------------------------------

    This proposal would also add reporting requirements to align with 
the energy conservation standards established in the April 2023 Air 
Cleaners DFR, which developed new energy conservation standards for air 
cleaners. Therefore, air cleaner manufacturers would incur additional 
paperwork costs. Air cleaners are classified under NAICS code 335210, 
``Small Electrical Appliance Manufacturing.'' The SBA sets a threshold 
of 1,500 employees or fewer for an entity to be considered as a small 
business for this category. DOE conducted a market survey to identify 
potential small manufacturers of air cleaners. DOE began its assessment 
by reviewing Association of Home Appliance Manufacturers' (AHAM's) 
database \38\ of air cleaners, models in ENERGY STAR V.2.0,\39\ 
California Air Resources Board,\40\ and individual company websites. 
DOE then consulted publicly available data, such as manufacturer 
websites, manufacturer specifications and product literature, and 
import/export logs (e.g., bills of lading from Panjiva \41\), to 
identify OEMs of air cleaners. DOE further relied on public data and 
subscription-based market research tools (e.g., Dun & Bradstreet 
reports \42\) to determine company, location, headcount, and annual 
revenue. DOE screened out companies that do not offer products covered 
by this proposed rulemaking, do not meet the SBA's definition of a 
``small business,'' or are foreign-owned and operated. DOE initially 
identified 43 OEMs that sell air cleaners in the United States. Of the 
43 OEMs identified, DOE tentatively determined four companies qualify 
as small businesses and are not foreign-owned and operated. DOE 
estimates that the increased certification burden would result in 35 
hours per manufacturer to develop the required certification reports. 
Therefore, based on a fully burdened labor rate of $67 per hour, the 
estimated total annual cost to manufacturers would be $2,345 per 
manufacturer.\43\ Using available public

[[Page 67494]]

information, DOE estimated the annual revenue for all four small 
businesses that manufacture air cleaners. The small business with the 
least annual revenue has an annual revenue of approximately $1.3 
million. Therefore, this additional certification cost of $2,345 per 
manufacturer represents significantly less than 1 percent of each 
identified manufacturer's annual revenue.

    DOE reviewed this proposed rule under the provisions of the 
Regulatory Flexibility Act and the policies and procedures published on 
February 19, 2003. On the basis of the forgoing, DOE initially 
concludes that the impacts of the amendments to DOE's certification 
regulations proposed in this NOPR would not have a ``significant 
economic impact on a substantial number of small entities.'' 
Accordingly, DOE has not prepared an IRFA for this NOPR. DOE will 
transmit this certification of no significant impact on a substantial 
number of small entities and supporting statement of factual basis to 
the Chief Counsel for Advocacy of the SBA for review under 5 U.S.C. 
605(b).

C. Review Under the Paperwork Reduction Act of 1995

    Manufacturers of CAC/HPs, DWs, RCWs, pool heaters, dehumidifiers, 
EPSs, battery chargers, CRACs, DX-DOASes, three-phase, less than 65,000 
Btu/h ACUACs and ACUHPs, three-phase, less than 65,000 Btu/h VRF, CWHs, 
ACIMs, walk-ins, commercial and industrial pumps, portable ACs,\44\ 
compressors, DPPPMs, air cleaners, and SPVUs must certify to DOE that 
their products comply with any applicable energy conservation 
standards. To certify compliance, manufacturers must first obtain test 
data for their products according to the DOE test procedures. DOE has 
established regulations for the certification and recordkeeping 
requirements for all covered consumer products and commercial 
equipment, including CAC/HPs, DWs, RCWs, pool heaters, dehumidifiers, 
EPSs, battery chargers, CRACs, DX-DOASes, three-phase, less than 65,000 
Btu/h ACUACs and ACUHPs, three-phase, less than 65,000 Btu/h VRF, CWHs, 
ACIMs, walk-ins, commercial and industrial pumps, portable ACs, 
compressors, DPPPMs, air cleaners, SPVUs, and CFLKs. (See generally 10 
CFR part 429.) The collection-of-information requirement for the 
certification and recordkeeping is subject to review and approval by 
OMB under the Paperwork Reduction Act (``PRA''). DOE's current 
reporting requirements are approved by OMB under OMB control number 
1910-1400. Public reporting burden for the certification is estimated 
to average 35 hours per response, including the time for reviewing 
instructions, searching existing data sources, gathering and 
maintaining the data needed, and completing and reviewing the 
collection of information.
---------------------------------------------------------------------------

    \44\ The certification reporting requirements for portable ACs 
were established in the January 2020 Portable ACs ECS Final Rule. 
However, the energy conversation standard for portable ACs does not 
go into effect until January 2025, until which time manufacturers 
may optionally submit certification reports to DOE.
---------------------------------------------------------------------------

1. Description of the Requirements
    DOE is proposing to establish or amend the reporting requirements 
for CAC/HPs, DWs, RCWs, pool heaters, dehumidifiers, EPSs, battery 
chargers, CRACs, DX-DOASes, three-phase, less than 65,000 Btu/h ACUACs 
and ACUHPs, three-phase, less than 65,000 Btu/h VRF, CWHs, ACIMs, walk-
ins, commercial and industrial pumps, portable ACs, compressors, 
DPPPMs, air cleaners, SPVUs, and CFLKs. DOE will send a revised 
information collection approval to OMB under the existing Control 
Number 1910-1400. The revisions will just reflect the changes proposed 
in this rulemaking as an amendment to the existing information 
collection.
2. Method of Collection
    DOE is proposing that respondents must submit electronic forms 
using DOE's online CCMS. DOE's CCMS is publicly accessible at 
www.regulations.doe.gov/ccms/, and includes instructions for users, 
registration forms, and the product-specific reporting templates 
required for use when submitting information to CCMS.
3. Data
    The following are DOE estimates of the total annual reporting and 
recordkeeping burden imposed on manufacturers of CAC/HPs, DWs, RCWs, 
pool heaters, dehumidifiers, EPSs, battery chargers, CRACs, DX-DOASes, 
three-phase, less than 65,000 Btu/h ACUACs and ACUHPs, three-phase, 
less than 65,000 Btu/h VRF, CWHs, ACIMs, walk-ins, commercial and 
industrial pumps, portable ACs, compressors, DPPPMs, air cleaners, 
SPVUs, and CFLKs subject to the new or amended certification reporting 
requirements proposed in this proposed rule. These estimates take into 
account the time necessary to develop any additional testing 
documentation, maintain any additional documentation supporting the 
development of the certified rating for each basic model, complete any 
additional certification, and submit any additional required documents 
to DOE electronically.
    DOE has tentatively determined that these proposed amendments would 
not impose additional costs for manufacturers of CAC/HPs, DWs, RCWs, 
dehumidifiers, EPSs, battery chargers, CRACs, three-phase, less than 
65,000 Btu/h ACUACs and ACUHPs, three-phase, less than 65,000 Btu/h 
VRF, electric storage CWHs, ACIMs, walk-ins, commercial and industrial 
pumps, compressors, SPVUs, and CFLKs because manufacturers of these 
products or equipment are already submitting certification reports to 
DOE and should have readily available the information that DOE is 
proposing to collect as part of this proposed rulemaking. Additionally, 
for portable ACs, manufacturers may optionally submit certification 
reports to DOE and the costs associated with certification requirements 
for portable ACs were already accounted for in the January 2020 
Portable ACs ECS Final Rule.
    DOE's proposed amendments for the reporting requirements for pool 
heaters would require new certification reporting for electric pool 
heater manufacturers and importers. DOE estimates there are 18 
manufacturers of electric pool heaters that would have to submit annual 
certification reports to DOE for those products based on the proposed 
reporting requirements. Of these 18 manufacturers, 4 make both gas-
fired and electric pool heaters. Therefore, 14 do not currently certify 
gas-fired pool heaters and would be required to begin submitting 
certification reports for electric pool heaters. The following section 
estimates the burden for these 14 electric pool heater manufacturers.
    OMB Control Number: 1910-1400.
    Form Number: DOE F 220.13.
    Type of Review: Regular submission.
    Affected Public: Domestic manufacturers and importers of electric 
pool heaters covered by this proposed rulemaking.
    Estimated Number of Respondents: 14.
    Estimated Time per Response: Certification reports, 35 hours.
    Estimated Total Annual Burden Hours: 490.
    Estimated Total Annual Cost to the Manufacturers: $32,830 in 
recordkeeping/reporting costs.
    DOE's proposed addition of reporting requirements for direct 
expansion-dedicated outdoor air systems would require new certification 
reporting for

[[Page 67495]]

direct expansion-dedicated outdoor air systems. DOE estimates there are 
12 manufacturers of direct expansion-dedicated outdoor air systems that 
would have to submit annual certification reports to DOE for those 
products based on the proposed reporting requirements. The following 
section estimates the burden for these 12 direct expansion-dedicated 
outdoor air system manufacturers.
    OMB Control Number: 1910-1400.
    Form Number: DOE F 220.96.
    Type of Review: Regular submission.
    Affected Public: Domestic manufacturers and importers of direct 
expansion-dedicated outdoor air systems covered by this proposed 
rulemaking.
    Estimated Number of Respondents: 12.
    Estimated Time per Response: Certification reports, 35 hours.
    Estimated Total Annual Burden Hours: 420.
    Estimated Total Annual Cost to the Manufacturers: $28,140 in 
recordkeeping/reporting costs.
    DOE's proposed addition of reporting requirements for commercial 
electric instantaneous water heaters would require new certification 
reporting for commercial electric instantaneous water heaters. DOE 
estimates there are 9 manufacturers of commercial electric 
instantaneous water heaters that would have to submit annual 
certification reports to DOE for those products based on the proposed 
reporting requirements. The following section estimates the burden for 
these 9 commercial electric instantaneous water heater manufacturers.
    OMB Control Number: 1910-1400.
    Form Number: DOE F 220.43.
    Type of Review: Regular submission.
    Affected Public: Domestic manufacturers and importers of commercial 
electric instantaneous water heater manufacturers covered by this 
proposed rulemaking.
    Estimated Number of Respondents: 9.
    Estimated Time per Response: Certification reports, 35 hours.
    Estimated Total Annual Burden Hours: 315.
    Estimated Total Annual Cost to the Manufacturers: $21,105 in 
recordkeeping/reporting costs.
    DOE's proposed amendments for the reporting requirements for 
dedicated-purpose pool pump motors would require new certification 
reporting for dedicated-purpose pool pump manufacturers and importers. 
DOE estimates there are five manufacturers of dedicated-purpose pool 
pump motors that would have to submit annual certification reports to 
DOE for those products based on the proposed reporting requirements. 
The following section estimates the burden for these five dedicated-
purpose pool pump motor manufacturers.
    OMB Control Number: 1910-1400.
    Form Number: DOE F 220.97.
    Type of Review: Regular submission.
    Affected Public: Domestic manufacturers and importers of dedicated-
purpose pool pump motors covered by this proposed rulemaking.
    Estimated Number of Respondents: 5.
    Estimated Time per Response: Certification reports, 35 hours.
    Estimated Total Annual Burden Hours: 175.
    Estimated Total Annual Cost to the Manufacturers: $11,725 in 
recordkeeping/reporting costs.
    DOE's proposed amendments for the reporting requirements for air 
cleaners would require new certification reporting for air cleaner 
manufacturers and importers. DOE estimates that there are 43 
manufacturers of air cleaners that would have to submit annual 
certification reports to DOE for those products based on the proposed 
reporting requirements. The following section estimates the burden for 
these 43 air cleaner manufacturers.
    OMB Control Number: 1910-1400.
    Form Number: DOE F 220.100.
    Type of Review: Regular submission.
    Affected Public: Domestic manufacturers and importers of air 
cleaners covered by this proposed rulemaking.
    Estimated Number of Respondents: 43.
    Estimated Time per Response: Certification reports, 35 hours.
    Estimated Total Annual Burden Hours: 1,505.
    Estimated Total Annual Cost to the Manufacturers: $100,835 in 
recordkeeping/reporting costs.
4. Conclusion
    DOE has tentatively concluded that the removal of outdated 
reporting requirements and the addition of reporting requirements as 
proposed in this NOPR would not impose additional costs for CAC/HPs, 
DWs, RCWs, dehumidifiers, EPSs, battery chargers, CRACs, three-phase, 
less than 65,000 Btu/h ACUACs and ACUHPs, three-phase, less than 65,000 
Btu/h VRF, electric storage CWHs, ACIMs, walk-ins coolers and freezers, 
commercial and industrial pumps, portable ACs, compressors, SPVUs, and 
CFLKs (see sections III.A.2, III.B.2, III.C.2, III.E.2, III.F.2, 
III.G.2, III.H.2, III.J.2, III.K.2, III.L.2, III.M.2, III.N.2, III.O.2, 
III.P.2, III.S.2, III.T.2, and III.U.2 of this document for a more 
complete discussion). Furthermore, DOE has tentatively concluded that 
there are 14 pool heater manufacturers, 12 DX-DOAS manufacturers, nine 
CWH manufacturers, five DPPPM manufacturers, and 43 air cleaner 
manufacturers that would newly be required to submit annual 
certification reports to DOE for those products. For all other 
manufacturers of covered products or equipment described in this NOPR, 
the public reporting burden for certification remains unchanged.
    Public comment is sought regarding: (1) Whether this proposed 
collection of information is necessary for the proper performance of 
the functions of the agency, including whether the information shall 
have practical utility; (2) the accuracy of the burden estimate; (3) 
ways to enhance the quality, utility, and clarity of the information to 
be collected; and (4) ways to minimize the burden of the collection of 
information, including through the use of automated collection 
techniques or other forms of information technology. Send comments on 
these or any other aspects of the collection of information to the 
email address listed in the ADDRESSES section and to the OMB Desk 
Officer by email to [email protected].
    Notwithstanding any other provision of the law, no person is 
required to respond to, nor shall any person be subject to a penalty 
for failure to comply with, a collection of information subject to the 
requirements of the PRA, unless that collection of information displays 
a currently valid OMB Control Number.

D. Review Under the National Environmental Policy Act of 1969

    In this NOPR, DOE proposes amended certification, reporting, and 
labeling requirements for CAC/HPs, DWs, RCWs, pool heaters, 
dehumidifiers, EPSs, battery chargers, CRACs, DX-DOASes, three-phase, 
less than 65,000 Btu/h ACUACs and ACUHPs, three-phase, less than 65,000 
Btu/h VRF, CWHs, ACIMs, walk-ins, commercial and industrial pumps, 
portable ACs, compressors, DPPPMs, air cleaners, SPVUs, and CFLKs. DOE 
has determined that this rule falls into a class of actions that are 
categorically excluded from review under the National Environmental 
Policy Act of 1969 (42 U.S.C. 4321 et seq.) and DOE's implementing 
regulations at 10 CFR part 1021. Specifically, DOE has determined that 
adopting test procedures for measuring energy efficiency of consumer 
products and industrial equipment is consistent with activities 
identified in 10 CFR part 1021, appendix A to subpart D, A5 and A6. 
Accordingly, neither an environmental assessment nor an

[[Page 67496]]

environmental impact statement is required.

E. Review Under Executive Order 13132

    Executive Order 13132, ``Federalism,'' 64 FR 43255 (Aug. 4, 1999) 
imposes certain requirements on agencies formulating and implementing 
policies or regulations that preempt State law or that have federalism 
implications. The Executive order requires agencies to examine the 
constitutional and statutory authority supporting any action that would 
limit the policymaking discretion of the States and to carefully assess 
the necessity for such actions. The Executive order also requires 
agencies to have an accountable process to ensure meaningful and timely 
input by State and local officials in the development of regulatory 
policies that have federalism implications. On March 14, 2000, DOE 
published a statement of policy describing the intergovernmental 
consultation process it will follow in the development of such 
regulations. 65 FR 13735. DOE has examined this proposed rule and has 
determined that it would not have a substantial direct effect on the 
States, on the relationship between the national government and the 
States, or on the distribution of power and responsibilities among the 
various levels of government. EPCA governs and prescribes Federal 
preemption of State regulations as to energy conservation for the 
products that are the subject of this proposed rule. States can 
petition DOE for exemption from such preemption to the extent, and 
based on criteria, set forth in EPCA. (42 U.S.C. 6297(d)) No further 
action is required by Executive Order 13132.

F. Review Under Executive Order 12988

    Regarding the review of existing regulations and the promulgation 
of new regulations, section 3(a) of Executive Order 12988, ``Civil 
Justice Reform,'' 61 FR 4729 (Feb. 7, 1996), imposes on Federal 
agencies the general duty to adhere to the following requirements: (1) 
eliminate drafting errors and ambiguity, (2) write regulations to 
minimize litigation, (3) provide a clear legal standard for affected 
conduct rather than a general standard, and (4) promote simplification 
and burden reduction. Section 3(b) of Executive Order 12988 
specifically requires that Executive agencies make every reasonable 
effort to ensure that the regulation (1) clearly specifies the 
preemptive effect, if any, (2) clearly specifies any effect on existing 
Federal law or regulation, (3) provides a clear legal standard for 
affected conduct while promoting simplification and burden reduction, 
(4) specifies the retroactive effect, if any, (5) adequately defines 
key terms, and (6) addresses other important issues affecting clarity 
and general draftsmanship under any guidelines issued by the Attorney 
General. Section 3(c) of Executive Order 12988 requires Executive 
agencies to review regulations in light of applicable standards in 
sections 3(a) and 3(b) to determine whether they are met or it is 
unreasonable to meet one or more of them. DOE has completed the 
required review and determined that, to the extent permitted by law, 
the proposed rule meets the relevant standards of Executive Order 
12988.

G. Review Under the Unfunded Mandates Reform Act of 1995

    Title II of the Unfunded Mandates Reform Act of 1995 (``UMRA'') 
requires each Federal agency to assess the effects of Federal 
regulatory actions on State, local, and Tribal governments and the 
private sector. Public Law 104-4, sec. 201 (codified at 2 U.S.C. 1531). 
For a proposed regulatory action likely to result in a rule that may 
cause the expenditure by State, local, and Tribal governments, in the 
aggregate, or by the private sector of $100 million or more in any one 
year (adjusted annually for inflation), section 202 of UMRA requires a 
Federal agency to publish a written statement that estimates the 
resulting costs, benefits, and other effects on the national economy. 
(2 U.S.C. 1532(a), (b)) The UMRA also requires a Federal agency to 
develop an effective process to permit timely input by elected officers 
of State, local, and Tribal governments on a proposed ``significant 
intergovernmental mandate,'' and requires an agency plan for giving 
notice and opportunity for timely input to potentially affected small 
governments before establishing any requirements that might 
significantly or uniquely affect small governments. On March 18, 1997, 
DOE published a statement of policy on its process for 
intergovernmental consultation under UMRA. 62 FR 12820; also available 
at www.energy.gov/gc/office-general-counsel. DOE examined this proposed 
rule according to UMRA and its statement of policy and determined that 
the rule contains neither an intergovernmental mandate, nor a mandate 
that may result in the expenditure of $100 million or more in any year, 
so these requirements do not apply.

H. Review Under the Treasury and General Government Appropriations Act, 
1999

    Section 654 of the Treasury and General Government Appropriations 
Act, 1999 (Pub. L. 105-277) requires Federal agencies to issue a Family 
Policymaking Assessment for any rule that may affect family well-being. 
This proposed rule would not have any impact on the autonomy or 
integrity of the family as an institution. Accordingly, DOE has 
concluded that it is not necessary to prepare a Family Policymaking 
Assessment.

I. Review Under Executive Order 12630

    DOE has determined, under Executive Order 12630, ``Governmental 
Actions and Interference with Constitutionally Protected Property 
Rights,'' 53 FR 8859 (March 18, 1988), that this proposed regulation 
would not result in any takings that might require compensation under 
the Fifth Amendment to the U.S. Constitution.

J. Review Under Treasury and General Government Appropriations Act, 
2001

    Section 515 of the Treasury and General Government Appropriations 
Act, 2001 (44 U.S.C. 3516 note) provides for agencies to review most 
disseminations of information to the public under guidelines 
established by each agency pursuant to general guidelines issued by 
OMB. OMB's guidelines were published at 67 FR 8452 (Feb. 22, 2002), and 
DOE's guidelines were published at 67 FR 62446 (Oct. 7, 2002). Pursuant 
to OMB Memorandum M-19-15, Improving Implementation of the Information 
Quality Act (April 24, 2019), DOE published updated guidelines which 
are available at www.energy.gov/sites/prod/files/2019/12/f70/DOE%20Final%20Updated%20IQA%20Guidelines%20Dec%202019.pdf. DOE has 
reviewed this proposed rule under the OMB and DOE guidelines and has 
concluded that it is consistent with applicable policies in those 
guidelines.

K. Review Under Executive Order 13211

    Executive Order 13211, ``Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use,'' 66 FR 28355 
(May 22, 2001), requires Federal agencies to prepare and submit to OMB, 
a Statement of Energy Effects for any proposed significant energy 
action. A ``significant energy action'' is defined as any action by an 
agency that promulgated or is expected to lead to promulgation of a 
final rule, and that (1) is a significant regulatory action under 
Executive Order 12866, or any successor order; and (2) is likely to 
have a significant adverse effect on the supply, distribution, or use 
of energy; or (3) is designated by the Administrator of OIRA as a 
significant energy action. For

[[Page 67497]]

any proposed significant energy action, the agency must give a detailed 
statement of any adverse effects on energy supply, distribution, or use 
should the proposal be implemented, and of reasonable alternatives to 
the action and their expected benefits on energy supply, distribution, 
and use.
    The proposed regulatory action is not a significant regulatory 
action under Executive Order 12866. Moreover, it would not have a 
significant adverse effect on the supply, distribution, or use of 
energy, nor has it been designated as a significant energy action by 
the Administrator of OIRA. Therefore, it is not a significant energy 
action, and, accordingly, DOE has not prepared a Statement of Energy 
Effects.

L. Review Under Section 32 of the Federal Energy Administration Act of 
1974

    Under section 301 of the Department of Energy Organization Act 
(Pub. L. 95-91; 42 U.S.C. 7101), DOE must comply with section 32 of the 
Federal Energy Administration Act of 1974, as amended by the Federal 
Energy Administration Authorization Act of 1977. (15 U.S.C. 788; 
``FEAA'') Section 32 essentially provides in relevant part that, where 
a proposed rule authorizes or requires use of commercial standards, the 
notice of proposed rulemaking must inform the public of the use and 
background of such standards. In addition, section 32(c) requires DOE 
to consult with the Attorney General and the Chairman of the Federal 
Trade Commission (``FTC'') concerning the impact of the commercial or 
industry standards on competition.
    The proposed modifications to the certification reporting and 
labeling requirements for CAC/HPs, DWs, RCWs, pool heaters, 
dehumidifiers, EPSs, battery chargers, CRACs, DX-DOASes, three-phase, 
less than 65,000 Btu/h ACUACs and ACUHPs, three-phase, less than 65,000 
Btu/h VRF, CWHs, ACIMs, walk-ins, commercial and industrial pumps, 
portable ACs, compressors, DPPPMs, air cleaners, SPVUs, and CFLKs do 
not incorporate testing methods contained in any commercial standards.

M. Description of Materials Incorporated by Reference

    DOE is proposing to remove the existing incorporation by reference 
of industry standard ANSI/AHAM DW-1-2010 from 10 CFR 429.4 and 429.19. 
No other changes are being proposed to materials incorporated by 
reference.

V. Public Participation

A. Participation in the Webinar

    The time and date of the webinar meeting are listed in the DATES 
section at the beginning of this document. Webinar registration 
information, participant instructions, and information about the 
capabilities available to webinar participants will be published on 
DOE's website: www.energy.gov/eere/buildings/implementation-certification-and-enforcement. Participants are responsible for 
ensuring their systems are compatible with the webinar software.

B. Procedure for Submitting Prepared General Statements for 
Distribution

    Any person who has an interest in the topics addressed in this 
proposed rule, or who is representative of a group or class of persons 
that has an interest in these issues, may request an opportunity to 
make an oral presentation at the webinar. Such persons may submit to 
[email protected]. Persons who wish to speak 
should include with their request a computer file in WordPerfect, 
Microsoft Word, PDF, or text (ASCII) file format that briefly describes 
the nature of their interest in this rulemaking and the topics they 
wish to discuss. Such persons should also provide a daytime telephone 
number where they can be reached.
    DOE requests persons selected to make an oral presentation to 
submit an advance copy of their statements at least two weeks before 
the webinar. At its discretion, DOE may permit persons who cannot 
supply an advance copy of their statement to participate, if those 
persons have made advance alternative arrangements with the Building 
Technologies Office. As necessary, requests to give an oral 
presentation should ask for such alternative arrangements.

C. Conduct of the Webinar

    DOE will designate a DOE official to preside at the webinar/public 
meeting and may also use a professional facilitator to aid discussion. 
The meeting will not be a judicial or evidentiary-type public hearing, 
but DOE will conduct it in accordance with section 336 of EPCA (42 
U.S.C. 6306). A court reporter will be present to record the 
proceedings and prepare a transcript. DOE reserves the right to 
schedule the order of presentations and to establish the procedures 
governing the conduct of the webinar. There shall not be discussion of 
proprietary information, costs or prices, market share, or other 
commercial matters regulated by U.S. anti-trust laws. After the webinar 
and until the end of the comment period, interested parties may submit 
further comments on the proceedings and any aspect of the rulemaking.
    The webinar will be conducted in an informal, conference style. DOE 
will a general overview of the topics addressed in this rulemaking, 
allow time for prepared general statements by participants, and 
encourage all interested parties to share their views on issues 
affecting this rulemaking. Each participant will be allowed to make a 
general statement (within time limits determined by DOE), before the 
discussion of specific topics. DOE will permit, as time permits, other 
participants to comment briefly on any general statements.
    At the end of all prepared statements on a topic, DOE will permit 
participants to clarify their statements briefly. Participants should 
be prepared to answer questions by DOE and by other participants 
concerning these issues. DOE representatives may also ask questions of 
participants concerning other matters relevant to this rulemaking. The 
official conducting the webinar/public meeting will accept additional 
comments or questions from those attending, as time permits. The 
presiding official will announce any further procedural rules or 
modification of the above procedures that may be needed for the proper 
conduct of the webinar.
    A transcript of the webinar will be included in the docket, which 
can be viewed as described in the Docket section at the beginning of 
this document. In addition, any person may buy a copy of the transcript 
from the transcribing reporter.

D. Submission of Comments

    DOE will accept comments, data, and information regarding this 
proposed rule before or after the public meeting, but no later than the 
date provided in the DATES section at the beginning of this proposed 
rule.\45\ Interested parties

[[Page 67498]]

may submit comments, data, and other information using any of the 
methods described in the ADDRESSES section at the beginning of this 
document.
---------------------------------------------------------------------------

    \45\ DOE has historically provided a 75-day comment period for 
test procedure NOPRs pursuant to the North American Free Trade 
Agreement, U.S.-Canada-Mexico (``NAFTA''), Dec. 17, 1992, 32 I.L.M. 
289 (1993); the North American Free Trade Agreement Implementation 
Act, Public Law 103-182, 107 Stat. 2057 (1993) (codified as amended 
at 10 U.S.C.A. 2576) (1993) (``NAFTA Implementation Act''); and 
Executive Order 12889, ``Implementation of the North American Free 
Trade Agreement,'' 58 FR 69681 (Dec. 30, 1993). However, on July 1, 
2020, the Agreement between the United States of America, the United 
Mexican States, and the United Canadian States (``USMCA''), Nov. 30, 
2018, 134 Stat. 11 (i.e., the successor to NAFTA), went into effect, 
and Congress's action in replacing NAFTA through the USMCA 
Implementation Act, 19 U.S.C. 4501 et seq. (2020), implies the 
repeal of E.O. 12889 and its 75-day comment period requirement for 
technical regulations. Thus, the controlling laws are EPCA and the 
USMCA Implementation Act. Consistent with EPCA's public comment 
period requirements for consumer products, the USMCA only requires a 
minimum comment period of 60 days. Consequently, DOE now provides a 
60-day public comment period for test procedure NOPRs.
