I. Background
A. Automatic Commercial Ice Makers
On November 1, 2022, DOE published a final rule in the Federal
Register amending the test procedure for automatic commercial ice
makers (``ACIMs'') (87 FR 65856; ``November 2022 ACIM Final Rule''). As
part of the November 2022 ACIM Final Rule, DOE codified certification
requirements for ACIMs at title 10 of the Code of Federal Regulations
(``CFR'') 429.45. However, in the publication of the November 2022 ACIM
Final Rule, DOE inadvertently updated 10 CFR 429.45(a)(2)(ii) with a
typographical error in the formula for the upper 95-percent confidence
limit (``UCL'') which used a ``minus'' sign instead of a ``plus'' sign
between the terms of the UCL formula (see 87 FR 65856, 65899 (Nov. 1,
2022)). This document identifies and corrects this error.
B. Integrated Light-Emitting Diode Lamps
On July 1, 2016, DOE published a final rule in the Federal Register
amending the test procedure for integrated light-emitting diode
(``LED'') lamps (81 FR 43404; ``July 2016 Integrated LED Lamps Final
Rule''). In the July 2016 Integrated LED Lamps Final Rule, DOE adopted
the requirement that testing of lumen output, input power, lamp
efficacy, power factor, correlated color temperature (``CCT''), color
rendering index (``CRI''), lifetime, and standby mode power (if
applicable) for integrated LED lamps be conducted by test laboratories
accredited by National Voluntary Laboratory Accreditation Program
(``NVLAP'') or an accrediting organization recognized by the
International Laboratory Accreditation Cooperation (``ILAC''), as
codified at 10 CFR 429.56(b)(2). Further, in the July 2016 Integrated
LED Lamps Final Rule, DOE provided that it would state directly that
accreditation by an Accreditation Body that is a signatory member to
the ILAC Mutual Recognition Arrangement (``MRA'') is an acceptable
means of laboratory accreditation. 81 FR 43404, 43419 (July 1, 2016).
However, DOE inadvertently did not update the certification
requirements for integrated LED lamps in 10 CFR 429.56(b)(2) to reflect
this statement. This document identifies and corrects this error by
specifying in 10 CFR 429.56(b)(2) that the certification report must
include the testing laboratory's ILAC accreditation body's
identification number or other approved identification assigned by the
ILAC accreditation body.
Additionally, in the July 2016 Integrated LED Lamps Final Rule, DOE
inadvertently updated 10 CFR 429.56(b)(2) to specify that lifetime be
reported in years. As indicated in the determinations of their
represented values in 10 CFR 429.56(a)(1)(ii)(D) and 10 CFR
429.56(a)(2), respectively, lifetime must be reported in hours and life
must be reported in years. This document identifies and corrects this
error.
C. General Service Lamps
On August 31, 2022, DOE published a final rule in the Federal
Register amending the test procedure for general service fluorescent
lamps (``GSFLs''), incandescent reflector lamps (``IRLs''), and general
service incandescent lamps (``GSILs'') (87 FR 53618; ``August 2022
Lamps Final Rule''). In the August 2022 Lamps Final Rule, DOE
reorganized 10 CFR 429.27 to apply only to GSFLs (as opposed to GSFLs,
GSILs, and IRLs), establishing new sections 10 CFR 429.55 for IRLs and
10 CFR 429.66 for GSILs, so that each lamp type (i.e., GSFL, IRL, GSIL)
has its own section within 10 CFR part 429. 87 FR 53618, 53629 (August
31, 2022). However, as part of the August 2022 Lamps Final Rule, DOE
inadvertently did not update the certification requirements for general
service lamps (``GSLs'') in 10 CFR 429.57 to change references to 10
CFR 429.27 to reflect this reorganization. Specifically, 10 CFR
429.57(a)(2), (a)(5) and (b)(3) refer to certification requirements for
GSILs at 10 CFR 429.27 when they should reference 10 CFR 429.66. This
document identifies and corrects this error.
Additionally, in the August 2022 Lamps Final Rule DOE clarified the
definition of ``rated wattage'' in 10 CFR 430.2, which included
replacing the references to appendix R with references to the relevant
sections in 10 CFR part 429. 87 FR 53618, 53629 (August 31, 2022).
However, in making
[[Page 6785]]
this update, with respect to GSILs, DOE inadvertently referenced 10 CFR
429.27 instead of 10 CFR 429.66 (see paragraph (2) of the ``rated
wattage'' definition in 10 CFR 430.2). This document identifies and
corrects this error.
D. Uninterruptible Power Supplies
On September 8, 2022, DOE published a final rule in the Federal
Register amending the battery charger portion of the battery charger
and uninterruptible power supply (``UPS'') test procedure at 10 CFR
part 430, subpart B, appendix Y (``appendix Y'') (87 FR 55090,
``September 2022 Battery Charger Final Rule''). The final rule also
created a new test procedure for both products at 10 CFR part 430,
subpart B, appendix Y1 (``appendix Y1'') that expanded the scope of the
battery charger test method and established separate metrics for active
mode, standby mode, and off mode for all battery chargers other than
uninterruptible power supplies. Manufacturers must continue to use the
amended test procedure in appendix Y until the compliance date of any
new final rule establishing amended energy conservation standards based
on the newly established test procedure in appendix Y1 (although early
compliance is permitted). 87 FR 55090, 55122 (Sept. 8. 2022). After the
compliance date of new standards for battery chargers other than UPSs
using these new metrics, manufacturers may no longer use appendix Y and
instead will be required to determine compliance using the updated test
procedure at appendix Y1. Id. at 87 FR 55125.
On April 19, 2024, DOE published a final rule in the Federal
Register (``April 2024 UPS Final Rule'') amending the UPS test
procedure in appendix Y and appendix Y1, which incorporated by
reference relevant portions of the latest version of the relevant
industry testing standard, harmonized the current DOE definitions with
the definitions in the latest version of the industry standard, and
added a no-load testing condition as an optional test. 89 FR 28581.
DOE has identified a reference error in both DOE's UPS enforcement
provisions at 10 CFR 429.134(o), as well as appendix Y of the UPS test
procedure. In 10 CFR 429.134(o), and in sections 0.1(d), 0.1(p),
0.1(q), 0.1(r), and 4.3.4 of appendix Y, DOE incorrectly referenced
sections 2.28.1 through 2.28.3 of appendix Y for UPS architecture
tests. The correct reference should be sections 2.27.1 through 2.27.3
of appendix Y. DOE additionally notes that the UPS enforcement
provisions should also have been updated to address how to determine
the UPS architecture of a unit tested using appendix Y1. This document
identifies and corrects these reference errors.
In the April 2024 UPS Final Rule, DOE also updated the introductory
note to appendix Y. 89 FR 28581, 28592 (April 19, 2024). DOE intended
to replace the introductory note, to add an introductory table, and to
remove the introductory text to appendix Y. However, as written, the
final rule did not remove the now-obsolete introductory text. This
document identifies and removes this text.
E. Water Heaters
The test procedure established for consumer water heaters and
residential-duty commercial water heaters is located in DOE's
regulations at 10 CFR part 430, subpart B, appendix E, ``Uniform Test
Method for Measuring the Energy Consumption of Water Heaters''
(``appendix E''), and it specifies that tests must be conducted under
specific conditions, depending on the type of water heater being
tested. On June 21, 2023, the DOE published a final rule in the Federal
Register adopting an amended test procedure for consumer water heaters
and residential-duty commercial water heaters (88 FR 40406; ``June 2023
Water Heater Final Rule'').
In the preamble to the June 2023 Water Heater final rule, DOE
discussed that it was amending the ambient air temperature tolerances
required for tests conducted on all water heaters other than heat pump
water heaters (i.e., for ``non-heat pump water heaters''), which was to
be specified at section 2.2.1 of appendix E. 88 FR 40406, 40435-40436
(June 21, 2023). Specifically, in section III.C.4 of the June 2023
Water Heater Final Rule, DOE explained that it had initially proposed
in a notice of proposed rulemaking (``NOPR'') published in the Federal
Register on January 11, 2022 (87 FR 1554; ``January 2022 Water Heater
NOPR'') to update the ambient temperature requirement for non-heat pump
water heaters to require that the ambient temperature during testing
must be an average of 67.5 [deg]F 2.5 [deg]F, with a
maximum deviation of 67.5 [deg]F 5 [deg]F, as opposed to
only a maximum deviation of 67.5 [deg]F 2.5 [deg]F as
specified in the test procedure at that time. In the June 2023 Water
Heater Final Rule, DOE concluded that, after considering comments on
the January 2022 Water Heater NOPR, it was adopting the changes to
ambient air temperature and relative humidity tolerances as proposed.
88 FR 40406, 40435-40436 (June 21, 2023).
However, the relevant regulatory text of section 2.2.1 in appendix
E, as amended by the June 2023 Water Heater Final Rule, does not
reflect these amended tolerances and improperly maintained the values
specified under the previous version of DOE's test procedure for the
subject water heaters. This document identifies and corrects this
error.
DOE also discovered a typographical error in section 6.3.2 of
appendix E. Section 6.3.2 of appendix E addresses the calculations for
mass of water removed during each draw of the 24-hour simulated-use
test. In that section, it is written that the volume of water must be
multiplied by the density of the water during each draw of the 24-hour
simulated-use test to arrive at the mass of water removed during each
draw of the 24-hour simulated-use test. Throughout appendix E, the
symbol [rho] (the lowercase symbol for the Greek letter ``rho'') is
used to represent density, including the definition for these values in
section 6.3.2 of appendix E. However, the first equation in section
6.3.2 of appendix E incorrectly uses the term Pdel,i, using
the letter P rather than the symbol [rho]. This document identifies and
corrects this error.
Additionally, a typographical error occurred which inadvertently
changed an equation in section 6.3.6 of appendix E. Section 6.3.6 of
appendix E addresses the calculation of adjusted daily water heating
energy consumption for water heaters with rated storage volumes greater
than or equal to 2 gallons, as well as circulating water heaters. In
that section, it is written that the difference between the energy used
to heat water in the test and the energy required to heat the same
quantity of water over a 67 [deg]F temperature rise (altogether
represented by the term QHWD) must be added to the adjusted
daily water heating energy consumption value to arrive at the daily
energy consumption value. However, the equation printed directly below
shows the terms being subtracted instead of being added together as the
text had indicated. The equation in section 6.3.6 of appendix E
specifically reads ``Qdm = Qda -
QHWD'' instead of properly reading ``Qdm =
Qda + QHWD.'' This document identifies and
corrects this error as well.
Another printing error caused the inadvertent deletion of the
mathematical equation from section 6.4.7 of appendix E that identifies
how to calculate the annual fossil fuel energy consumption of a water
heater with rated storage volume less than 2 gallons. The annual fossil
fuel energy consumption for such a product is equal to the total annual
energy consumption
[[Page 6786]]
minus the electrical energy consumption (adjusted from kilowatts to Btu
per hour). Thus, the equation should read, ``Eannual,f =
Eannual - (Eannual,e x 3,412)'' as it did in
section 6.4.6 of appendix E prior to the June 2023 Water Heater Final
Rule which renumbered the section. This document identifies and
corrects this error.
This document also identifies and corrects typographical errors
pertaining to the amended standards for water heaters found at 10 CFR
430.32(d). On May 6, 2024, DOE published a final rule in the Federal
Register adopting amended energy conservation standards for consumer
water heaters (89 FR 37778; ``May 2024 Water Heater Final Rule'').
Throughout the May 2024 Water Heater Final Rule, DOE discussed
transitioning standards for consumer water heaters to be based on an
effective storage volume metric, as opposed to the previously used
rated storage volume metric. Table I.1 in the May 2024 Water Heater
Final Rule demonstrated how the amended standards (with compliance
required beginning on May 6, 2029) would be based on effective storage
volume. Id. at 89 FR 37780-37781. However, when adopting these
standards into the regulatory text codified at 10 CFR 430.32(d)(2), the
table inadvertently maintained a reference to the rated storage volume
metric. Id. at 89 FR 37944. This document corrects the amended
standards table to read ``Effective storage volume and input rating (if
applicable)'' instead of ``Rated storage volume and input rating (if
applicable)'' at 10 CFR 430.32(d)(2).
In addition, the current standards, which use the rated storage
volume metric, remain applicable until May 6, 2029. The May 2024 Water
Heater Final Rule maintained these standards at 10 CFR 430.32(d)(1).
However, the adopted regulatory text at 10 CFR 430.32(d)(1) included a
typographical error with respect to the compliance dates for the
standards therein. Section (d)(1) of 10 CFR 430.32 reads ``The uniform
energy factor of water heaters manufactured May 6, 2029 shall not be
less than the following'' instead of ``The uniform energy factor of
water heaters manufactured before May 6, 2029 shall not be less than
the following'' (emphasis added on the word ``before''). This document
corrects this error as well.
F. Portable Air Conditioners
On May 15, 2023, DOE published a final rule in the Federal Register
establishing a new test procedure for portable air conditioners
(``ACs'') at 10 CFR part 430, subpart B, appendix CC1, ``Uniform Test
Method for Measuring the Energy Consumption of Portable Air
Conditioners'' (``appendix CC1'') (88 FR 31102; ``May 2023 Portable AC
Final Rule''). This test procedure must be used to determine compliance
with any amended portable AC energy conservation standards that use the
Annualized Energy Efficiency Ratio (``AEER'') metric. 88 FR 31102,
31106 (May 15, 2023). In the May 2023 Portable AC Final Rule, as part
of appendix CC1, DOE adopted an updated seasonally adjusted cooling
capacity (``SACC'') calculation that consists of a weighted average of
the cooling capacities measured at the 95 [deg]F and 83 [deg]F test
conditions, each adjusted for duct heat transfer capacity losses and
infiltration air capacity losses. For single-speed portable ACs, the
adjusted cooling capacity for the 83 [deg]F test condition is also
multiplied by a load factor of 0.6 for single-duct units and 0.5363 for
dual-duct units. 88 FR 31102, 31114 (May 15, 2023).
DOE has identified an error in section 5.1 of appendix CC1, which
contains the calculations of adjusted cooling capacity for portable ACs
at the 95 [deg]F and 83 [deg]F operating conditions. The identified
error is in the formula for adjusted cooling capacity of single-duct
single-speed units at 83 [deg]F (``ACC83''), which as
published includes the term ``Qinfiltration_95,'' This term
was included erroneously, and the formula should have used the term
``Qinfiltration_83'' to reflect the infiltration heat
transfer at 83 [deg]F rather than at 95 [deg]F as is currently shown.
This erroneous term is also included in the amplifying instruction for
single-speed single-duct units in that section, which should reference
the Qinfiltration_83 value in addition to
Qinfiltration_95. This document identifies and corrects
these errors.
G. Refrigerators, Refrigerator-Freezers, and Freezers
On January 17, 2024, DOE published a direct final rule in the
Federal Register adopting amended energy conservation standards for
refrigerators, refrigerator-freezers, and freezers (89 FR 3026;
``January 2024 Refrigerator Direct Final Rule''). In the publication of
the January 2024 Refrigerator Direct Final Rule, DOE inadvertently
updated 10 CFR 430.32(a)(1) with a typographical error which states the
current energy conservation standards for refrigerators, refrigerator-
freezers, and freezers ``apply to products manufactured on or before
September 15, 2014.'' This document identifies and corrects this error,
with text that reads ``standards apply to products manufactured on or
after September 15, 2014.''
In the January 2024 Refrigerator Direct Final Rule, DOE also
inadvertently updated 10 CFR 430.32(a)(1) with another typographical
error which lists the equation for the maximum energy use for product
class 4I-BI as ``10.22AV + 441.4.2.'' This document identifies and
corrects this error, to reflect the correct equation of ``10.22AV +
441.4.''
H. Commercial Package Air Conditioners and Heat Pumps
On May 20, 2024, DOE published a final rule in the Federal Register
amending the current test procedures for air-cooled commercial unitary
air conditioners with a rated cooling capacity greater than or equal to
65,000 Btu/h, evaporatively-cooled commercial unitary air conditioners,
and water-cooled commercial unitary air conditioners (referred to
collectively as ``CUACs and CUHPs'') (89 FR 43986; ``May 2024 CUAC and
CUHP TP Final Rule'').
As part of the publication of the May 2024 CUAC and CUHP TP Final
Rule, DOE updated Table 1 to paragraph (b) of 10 CFR 431.96, which
lists the test procedure for all commercial air conditioners and heat
pumps, and included a typographical error in one of the column headers.
Specifically, the column heading in Table 1 to paragraph (b)
erroneously stated, ``Use tests, conditions, an procedures in'' instead
of ``Use tests, conditions and procedures in'' (see 89 FR 43986, 44037
(May 20, 2024). This document identifies and corrects this error.
I. Distribution Transformers
The applicable energy conservation standard requirements for
distribution transformers are contained in DOE's regulations at 10 CFR
part 431, subpart K and are applicable to products that meet the
definition of ``distribution transformer'' as codified at 10 CFR
431.192. 10 CFR 431.192 also includes definitions for several kinds of
equipment explicitly excluded from the definition of ``distribution
transformer.''
On April 22, 2024, DOE published a final rule in the Federal
Register adopting amended energy conservation standards for
distribution transformers and adopting minor edits to the definitions
relevant for distribution transformers, including clarifying edits to
the definition of ``special-impedance transformer'' (89 FR 29834;
``April 2024 Transformer Final Rule''). In the publication of the April
2024 Transformer Final Rule, DOE updated 10 CFR 431.192 with a
typographical error in the titles of Tables 1 and 2 relevant for the
definition of ``special-impedance transformer.'' Specifically,
[[Page 6787]]
the headings for Table 1 and Table 2 each state, ``to the Definition o
`Special-Impedance Transformer.' '' This document identifies and
corrects this error with text that reads, ``to the Definition of
`Special-Impedance Transformer.' ''
J. Walk-In Coolers and Walk-In Freezers
On May 4, 2023, DOE published a final rule in the Federal Register
amending the test procedures for walk-in coolers and walk-in freezers
(referred to as ``walk-ins'' or ``WICFs'') (88 FR 28780; ``May 2023
WICF TP Final Rule''). As part of the May 2023 WICF TP Final Rule, DOE
adopted a new test procedure at 10 CFR part 431, subpart R, appendix C1
(``appendix C1'') and a new efficiency metric (i.e., annual walk-in
energy factor 2 (``AWEF2'')), for walk-in refrigeration systems.
Appendix C1 references the Air-Conditioning, Heating, and Refrigeration
Institute (``AHRI'') industry test standard AHRI 1250-2020, ``2020
Standard for Performance Rating of Walk-in Coolers and Freezers.''
AWEF2 is the ratio of annual total heat removed from a walk-in box
(i.e., the annual walk-in box load) to the annual total energy input.
For all outdoor dedicated condensing refrigeration systems (i.e.,
outdoor matched pairs, single-package dedicated systems, and dedicated
condensing units), annual walk-in box load and annual energy use are
determined by summing the walk-in box load and energy use for 20
different bins and corresponding bin temperatures multiplied by the
number of hours in each bin (see, e.g., section 7.4.1 of AHRI 1250-
2020). Power values for each bin are interpolated or extrapolated based
on the power measurements taken at three different outdoor ambient
temperatures (95 [deg]F, 59 [deg]F, and 35 [deg]F). For outdoor
dedicated condensing refrigeration systems, there are three off-cycle
tests conducted at these same three outdoor ambient conditions (95
[deg]F, 59 [deg]F, and 35 [deg]F), and, therefore, there are three
separate measurements of off-cycle condensing unit power (see, e.g.,
Table 5 of AHRI 1250-2020).
In the May 2023 WICF TP Final Rule, for outdoor dedicated
condensing refrigeration systems, DOE deviated from the AHRI 1250-2020
calculations for off-cycle energy use in AWEF2 because the equations
for refrigeration system total power input by each bin temperature tj
(e.g., equation 13 of AHRI 1250-2020) do not use off-cycle power values
that vary by bin temperature. Because the condensing unit off-cycle
power may vary as a function of outdoor temperature, DOE adopted
instructions for calculating condensing unit off-cycle power as a
function of outdoor temperature based on the measurements made at the
three outdoor test condition temperatures. 88 FR 28780, 28812-28813
(May 4, 2023). DOE adopted these provisions for all outdoor dedicated
condensing systems, regardless of whether they are high-, medium-, or
low-temperature dedicated condensing systems.
Section 3.4.12.2 of appendix C1 specifies how to calculate AWEF2
for high-temperature, outdoor matched pairs or single-packaged
refrigeration systems. Section 3.4.12.2 erroneously specifies that the
condensing unit off-cycle power, Ecu,off, is measured as described in
section C3.5 of AHRI 1250-2020 and does not specify that condensing
unit off-cycle power should be determined based on bin temperature tj
per section 3.4.3.3 of appendix C1. This document identifies and
corrects this error with text that specify that condensing unit off-
cycle power for high-temperature, outdoor matched pairs or single-
packaged refrigeration systems should be determined based on bin
temperature tj per section 3.4.3.3 of appendix C1.
K. Circulator Pumps
On May 20, 2024, DOE published a final rule in the Federal Register
establishing energy conservation standards for circulator pumps (89 FR
44464; ``May 2024 Circulator Pump Final Rule''). In the publication of
the May 2024 Circulator Pump Final Rule, DOE updated the section
heading of 10 CFR 431.465 which previously read ``Pumps energy
conservation standards and their compliance dates'' to read
``Circulator pumps energy conservation standards and their compliance
dates.'' This amendment was in error, as this section of the CFR
includes energy conservation standards for dedicated purpose pool pumps
and commercial and industrial pumps in addition to circulator pumps.
This document identifies and corrects this error by reverting to the
previous section heading.
L. Commercial and Industrial Pumps
The test procedure established for commercial and industrial pumps
is located in DOE's regulations at 10 CFR part 431, subpart Y, appendix
A, ``Uniform Test Method for the Measurement of Energy Consumption of
Pumps'' (``appendix A''). Sections IV.D.2 and VI.D.2 of appendix A
outline how to determine the best efficiency point (``BEP'') using the
testing-based approach for pumps sold with motors. On March 24, 2023,
DOE published a final rule in the Federal Register adopting an amended
test procedure for commercial and industrial pumps (88 FR 17934;
``March 2023 Pumps Final Rule'').
DOE has identified errors in sections IV.D.2 and VI.D.2 of appendix
A, as finalized in the March 2023 Pumps Final Rule, which erroneously
reference ``pump efficiency,'' calculated using ``pump power input,''
in describing how to determine the BEP using the testing-based approach
for pumps sold with motors; whereas, those sections should instead
reference ``overall efficiency,'' calculated using ``driver power
input,'' consistent with the wording as it appeared prior to the
amendments of the March 2023 Pumps Final Rule. This document identifies
and corrects these errors by reverting to the prior language.
II. Need for Correction
A. Automatic Commercial Ice Makers
As published, the regulatory text in 10 CFR 429.45(a)(2)(ii) will
likely cause confusion and may mislead interested parties regarding how
to properly determine the UCL for ACIM certification purposes. The
relevant changes to 10 CFR 429.45(a)(2)(ii) correct the inadvertent
formula error. Accordingly, the changes addressed in this document are
technical in nature.
B. Integrated Light-Emitting Diode Lamps
As published, the regulatory text in 10 CFR 429.56(b)(2) will
likely cause confusion and may mislead interested parties regarding the
entities permitted to test integrated LED lamps and the units to be
used in making certain representations. The relevant changes to 10 CFR
429.56(b)(2) correct the units used and the testing laboratory
requirements. Accordingly, the changes addressed in this document are
technical in nature.
C. General Service Lamps
As published, the erroneous section references in the regulatory
text in sections (a) and (b) of 10 CFR 429.57 and the definition of
``rated wattage'' in 10 CFR 430.2 will likely cause confusion and may
mislead interested parties regarding how to properly test and certify
GSFLs, IRLs, and GSILs. The relevant changes to sections (a) and (b) of
10 CFR 429.57 and the definition of ``rated wattage'' in 10 CFR 430.2
correct the reference errors. Accordingly, the changes addressed in
this document are technical in nature.
D. Uninterruptible Power Supplies
As published, the now-obsolete introductory text in appendix Y, the
[[Page 6788]]
erroneous section references in the regulatory text in 10 CFR
429.134(o), and sections 0 and 4.3.4 of appendix Y will likely cause
confusion and may mislead interested parties regarding test procedure
applicability date, and regarding how to properly determine UPS
architecture. The relevant changes to 10 CFR 429.134(o) and sections 0
and 4.3.4 of appendix Y correct the reference errors related to UPS
architecture testing. Accordingly, the changes addressed in this
document are technical in nature.
E. Water Heaters
As published, the regulatory text in sections 2.2.1, 6.3.6, and
6.4.7 of appendix E, will likely cause confusion and may mislead
interested parties regarding how to properly conduct testing under
DOE's consumer water heaters and residential-duty commercial water
heaters test procedure. The relevant changes to section 2.2.1 of
appendix E, involving a tolerance to ambient temperature requirement
for non-heat pump water heaters, was discussed in the June 2023 Water
Heater Final Rule's preamble, but it was inadvertently omitted from the
amended regulatory text. The relevant changes to section 6.3.2 and
section 6.3.6 of appendix E, involving the proper nomenclature for mass
of water removed and the proper calculation of daily energy
consumption, respectively, fix inadvertent typographical errors. The
changes to section 6.4.7 of appendix E correct the inadvertent deletion
of an equation used to compute annual fossil fuel energy consumption.
Additionally, the relevant changes to the amended standards at 10 CFR
430.32(d)(1)-(2), involving the description of the compliance date and
the storage volume metric, also resolve inadvertent typographical
errors. Accordingly, the changes addressed in this document are
technical in nature.
F. Portable Air Conditioners
As published, the regulatory text in section 5.1 of appendix CC1 to
subpart B of 10 CFR part 430 will likely result in confusion as to the
meaning of these terms and the references to provisions elsewhere in
the test procedure. The relevant changes to section 5.1 of appendix CC1
correct the typographical errors introduced in the May 2023 Portable AC
Final Rule. Accordingly, the changes addressed in this document are
technical in nature.
G. Refrigerators, Refrigerator-Freezers, and Freezers
As published, the regulatory text in 10 CFR 430.32(a)(1) will
likely cause confusion and may mislead interested parties regarding
applicability of the current energy conservation standards of
refrigerators, refrigerator-freezers, and freezers. The relevant
changes to 10 CFR 430.32(a)(1), correct the inadvertent typographical
errors introduced in the January 2024 Refrigerator Direct Final Rule.
Accordingly, the changes addressed in this document are editorial in
nature.
H. Commercial Package Air Conditioners and Heat Pumps
As published, the regulatory text in section 10 CFR 431.96 may
cause confusion to interested parties regarding how to properly conduct
testing under DOE's commercial air conditioner and heat pump test
procedures. The relevant changes to 10 CFR 431.96 correct the
typographical error introduced in the May 2024 CUAC and CUHP TP Final
Rule. Accordingly, the changes addressed in this document are editorial
in nature.
I. Distribution Transformers
As published, the regulatory text in section 10 CFR 431.192 will
likely cause confusion to interested parties regarding definitions
relevant to the current energy conservation standards of distribution
transformers. The relevant changes to 10 CFR 431.192 correct the
typographical error introduced in the April 2024 Transformer Final
Rule. Accordingly, the changes addressed in this document are editorial
in nature.
J. Walk-In Coolers and Walk-In Freezers
As published, the regulatory text in section 3.4.12.2 of 10 CFR
part 431, subpart R, appendix C1 will likely cause confusion and may
mislead interested parties regarding how to properly conduct testing of
high-temperature, outdoor matched pairs or single-packaged dedicated
condensing systems under DOE's walk-in refrigeration systems test
procedure. The relevant changes to section 3.4.12.2 of appendix C1
correct the inadvertent error introduced in the May 2023 WICF TP Final
Rule. Accordingly, the changes addressed in this document are technical
in nature.
K. Circulator Pumps
As published, the title of 10 CFR 431.465 will likely cause
confusion and may mislead interested parties regarding the current
energy conservation standards of dedicated purpose pool pumps and
commercial and industrial pumps. The relevant changes to 10 CFR 431.465
correct the misleading section heading introduced in the May 2024
Circulator Pump Final Rule. Accordingly, the changes addressed in this
document are editorial in nature.
L. Commercial and Industrial Pumps
As published, the regulatory text in sections IV.D.2 and VI.D.2 of
appendix A to subpart Y of 10 CFR part 431 will likely cause confusion
and may mislead interested parties regarding how to properly conduct
testing under DOE's commercial and industrial pump test procedure. The
relevant changes to 10 CFR part 431, subpart Y, appendix A correct the
inadvertent error introduced in the March 2023 Pumps Final Rule.
Accordingly, the changes addressed in this document are technical in
nature.

Pursuant to the Administrative Procedure Act, 5 U.S.C. 553(b)(B),
DOE finds that there is good cause to not issue a separate notification
to solicit public comment on the changes contained in this document.
Issuing a separate notification to solicit public comment would be
impracticable, unnecessary, and contrary to the public interest.
Neither the errors nor the corrections in this document affect the
substance of the aforementioned final rules for the subject consumer
products and commercial and industrial equipment or any of the
conclusions reached in support of those documents. Additionally, given
the energy conservation standards and test procedures that are being
corrected are
[[Page 6789]]
a result of an extensive administrative record with numerous
opportunities for public comment, DOE finds additional comment on the
technical corrections is unnecessary. Therefore, providing prior
notification and an opportunity for public comment on correcting
objective, typographical errors that do not change the substance of the
relevant energy conservation standards and test procedures serves no
useful purpose.
Further, this rule correcting typographical errors makes non-
substantive changes to the subject test procedure and energy
conservation standards. As such, this rule is not subject to the 30-day
delay in effective date requirement of 5 U.S.C. 553(d) otherwise
applicable to rules that make substantive changes.
The following standards appear in the amendatory text of this
document and were previously approved for the locations in which they
appear: ANSI C78.81, ANSI C78.901, AHAM PAC-1-2022, AHRI 1250-2020, and
HI 40.6-2021.

8. Amend appendix E to subpart B of part 430 by revising sections
2.2.1, 6.3.2, 6.3.6, and 6.4.7 to read as follows:
Appendix E to Subpart B of Part 430--Uniform Test Method for Measuring
the Energy Consumption of Water Heaters
* * * * *
2.
* * *
2.2 * * *
2.2.1 Non-Heat Pump Water Heaters. The ambient air temperature
shall be maintained at an average of 67.5 [deg]F 2.5
[deg]F (19.7 [deg]C 1.4 [deg]C) on a continuous basis
throughout the test, with a maximum deviation of 67.5 [deg]F 5 [deg]F (19.7 [deg]C 2.8 [deg]C).
* * * * *
6. * * *
6.3 * * *
6.3.2 Mass of Water Removed. Determine the mass of water removed
during each draw of the 24-hour simulated-use test
(Mdel,i) as:
If the mass of water removed is measured, use the measured
value, or, if the volume of water removed is being measured,
Mdel,i = Vdel,i x rdel,i
* * * * *
6.3.6 Adjusted Daily Water Heating Energy Consumption. The
adjusted daily water heating energy consumption, Qda,
takes into account that the ambient temperature may differ from the
nominal value of 67.5 [deg]F (19.7 [deg]C) due to the allowable
variation in surrounding ambient temperature of 65 [deg]F (18.3
[deg]C) to 70 [deg]C (21.1 [deg]C). The adjusted daily water heating
energy consumption is computed as:
Qda = Qd-(67.5 [deg]F-Ta,stby,2) UA tstby,2
or,
Qda = Qd-(19.7 [deg]C-Ta,stby,2) UA tstby,2
Where:
Qda = the adjusted daily water heating energy
consumption, Btu (kJ).
Qd = as defined in section 6.3.4 of this appendix.
Ta,stby,2 = the average ambient temperature during the
total standby portion, tstby,2, of the 24-hour simulated-
use test, [deg]F ([deg]C).
UA = as defined in section 6.3.4 of this appendix.
Tstby,2 = the number of hours during the 24-hour
simulated-use test when water is not being withdrawn from the water
heater.
A modification is also needed to take into account that the
temperature difference between the outlet water temperature and
supply water temperature may not be equivalent to the nominal value
of 67 [deg]F (125 [deg]F-58 [deg]F) or 37.3 [deg]C (51.7 [deg]C-14.4
[deg]C). The following equations adjust the experimental data to a
nominal 67 [deg]F (37.3 [deg]C) temperature rise.
The energy used to heat water, Btu/day (kJ/day), may be computed
as:
[GRAPHIC] [TIFF OMITTED] TR21JA25.085
Where:
N = total number of draws in the 24-hour simulated-use test.
Mdel,i = the mass of water removed during the ith draw (i
= 1 to N) as calculated in section 6.3.2 of this appendix, lb (kg).
Cpi = the specific heat of the water withdrawn during the
ith draw of the 24-hour simulated-use test, evaluated at
(Tdel,i + Tin,i)/2, Btu/(lb[middot][deg]F)
(kJ/(kg[middot][deg]C)).
Tdel,i = the average water outlet temperature measured
during the ith draw (i = 1 to N), [deg]F ([deg]C).
Tin,i = the average water inlet temperature measured
during the ith draw (i = 1 to N), [deg]F ([deg]C).
hr = as defined in section 6.3.3 of this appendix.
The energy required to heat the same quantity of water over a 67
[deg]F (37.3 [deg]C) temperature rise, Btu/day (kJ/day), is:
[GRAPHIC] [TIFF OMITTED] TR21JA25.086
or,
[GRAPHIC] [TIFF OMITTED] TR21JA25.087
[[Page 6791]]
The difference between these two values is:
QHWD = QHW,67[deg]F-QHW
or,
QHWD = QHW,37.3[deg]C-QHW
This difference (QHWD) must be added to the adjusted
daily water heating energy consumption value. Thus, the daily energy
consumption value, which takes into account that the ambient
temperature may not be 67.5 [deg]F (19.7 [deg]C) and that the
temperature rise across the storage tank may not be 67 [deg]F (37.3
[deg]C) is:
Qdm = Qda + QHWD
* * * * *
6.4 * * *
6.4.7 Annual Fossil Fuel Energy Consumption. The annual fossil
fuel energy consumption for water heaters with rated storage volumes
less than 2 gallons, Eannual,f, is computed as:
Eannual,f = Eannual-(Eannual,e x 3412)
Where:
Eannual = the annual energy consumption as defined in section 6.4.5
of this appendix, Btu (kJ).
Eannual,e = the annual electrical energy consumption as defined in
section 6.4.6 of this appendix, kWh.
3412 = conversion factor from kWh to Btu.

9. Amend appendix Y to subpart B of part 430 by revising Note 1 and
table and sections 0.1(d), 0.1(p), 0.1(q), 0.1(r), and 4.3.4 to read as
follows:

5.1 Adjusted Cooling Capacity. Calculate the adjusted cooling
capacities at the 95 [deg]F and 83 [deg]F operating conditions
specified below of the sample unit, in Btu/h, according to the
following equations.
For a single-duct single-speed unit:
ACC95 = CapacitySD - Qduct\SD - Qinfiltration\95
ACC83 = 0.6000 x (CapacitySD - Qduct\SD - Qinfiltration\83)
For a single-duct variable-speed unit:
ACC95 = CapacitySD\Full - Qduct\SD\Full - Qinfiltration\95
ACC83 = CapacitySD\Low - Qduct\SD\Low - Qinfiltration\83\Low
For a dual-duct single-speed unit:
ACC95 = CapacityDD\95\Full - Qduct\DD\95\Full - Qinfiltration\95
ACC83 = 0.5363 x (CapacityDD\83 - Qduct\DD\83 - Qinfiltration\83)
For a dual-duct variable-speed unit:
ACC95 = CapacityDD\95\Full - Qduct\DD\95\Full - Qinfiltration\95
ACC83 = CapacityDD\Low - Qduct\DD\83\Low - Qinfiltration\83\Low
Where:
ACC95 and ACC 83 = adjusted cooling capacity
