SUMMARY:
rmajette on DSK2TPTVN1PROD with RULES
I. Background
On June 8, 2016, DOE’s Office of
Energy Efficiency and Renewable
Energy published a test procedure final
rule in the Federal Register titled, ‘‘Test
Procedures for Central Air Conditioners
and Heat Pumps’’ (‘‘June 2016 final
rule’’). 81 FR 36992. Since the
publication of that final rule, it has
VerDate Sep<11>2014
15:00 Aug 17, 2016
Jkt 238001
come to DOE’s attention that, due to a
technical oversight, certain portions of
the regulatory text adopted in the June
2016 final rule for 10 CFR part 429 and
appendix M to subpart B of 10 CFR part
430 (‘‘appendix M’’) contained editorial
errors.
As part of that final rule, DOE
amended 10 CFR 429.16, which
addresses certification of central air
conditioners and heat pumps, and 10
CFR 429.70, which addresses alternate
efficiency determination methods. This
correction addresses editorial errors in
§ 429.16(a)(1), (d)(1), (d)(2), and (e)(4).
Specifically, at § 429.16(a)(1), DOE
included a cross reference to paragraph
(c)(2) that should have referred to
paragraph (b)(2)(i). In § 429.16(d)(1) and
(2), DOE mistakenly transposed the
words ‘‘less’’ and ‘‘greater.’’ At
§ 429.16(e)(4), DOE erroneously referred
to cubic feet per minute (cfm) instead of
cubic feet per minute of standard air
(scfm). At § 429.16(e)(4)(viii), DOE
failed to remove regulatory text
associated with changes to the test
procedure for variable speed heat
pumps not adopted in the June 2016
final rule that had been proposed on
November 9, 2015 in a supplementary
notice of proposed rulemaking
(‘‘November 2015 SNOPR’’). 80 FR
69278. In order to remedy these errors,
DOE is issuing this final rule correction
to revise the text in these sections.
In addition, the June 2016 final rule
revised appendix M to subpart B of 10
CFR part 430 (‘‘appendix M’’), which
specifies the ‘‘Uniform Test Method for
the Measurement the Energy
Consumption of Central Air
Conditioners and Heat Pumps.’’ This
correction also addresses several
editorial errors in appendix M.
In section 3.11.1 of appendix M, ‘‘If
using the outdoor air enthalpy method
as the secondary test method,’’ DOE
erroneously numbered two subsections
with the number ‘‘3.11.1.1.’’ The second
of these two is renumbered to
‘‘3.11.1.2.’’
In section 4.1 of appendix M,
‘‘Seasonal Energy Efficiency Ratio
(SEER) Calculations,’’ DOE erroneously
numbered subsection 4.1.3 as ‘‘4.1.2.3,’’
which propagated errors in numbering
from that point through the end of
section 4.1 and created erroneous crossreferences to these sections. Section
4.1.2.3 is renumbered as section ‘‘4.1.3,’’
and the following section numbers
PO 00000
Frm 00001
Fmt 4700
Sfmt 4700
through the end of section 4.1 are
renumbered accordingly. Additionally,
cross-references to the renumbered
sections are revised.
Sections 2.11 and 3.19 of appendix M
contain errors in the tolerance allowed
between temperature measurements.
The preamble to the June 2016 final rule
states that the maximum allowable
temperature difference is 2.0 °F and that
it applies to the average measurements
for the test period. 81 FR 36991, 37028
(June 8, 2016). In section 2.11, DOE
erroneously referred to ‘‘maximum
difference between readings’’ rather
than adding the clarification discussed
in the preamble that ‘‘readings’’ referred
to the average temperatures measured
during the test period. In section 3.1.9,
DOE similarly failed to include the
clarifying information on the tolerance
and erroneously provided a tolerance of
1.5 °F rather than 2.0 °F. DOE is
correcting section 2.11 accordingly and
correcting 3.1.9 to refer directly to
section 2.11 rather than correcting the
provided tolerance.
Tables 8, 9, 15, 16, and 17 of
appendix M contained various errors in
testing tolerances for external resistance
to airflow, airflow nozzle pressure
difference, and electric voltage. In the
preamble of the June 2016 Final Rule,
DOE explained its intention to maintain
the external resistance to airflow
tolerance at 0.05 inches of water, to
maintain the airflow nozzle pressure
difference tolerance at 2.0%, and to
maintain the electric voltage tolerance at
2.0%. 81 FR 36991, 37036 (June 8,
2016). However, this was not reflected
in tables 8, 9, 15, 16 and 17 of appendix
M, and the tables are revised to reflect
these corrections.
In section 3.13.1.d of appendix M, P2x
was erroneously printed instead of Px in
two instances. This section provides
instructions for measurement of the
indoor unit low voltage power Px, which
is later subtracted from the
measurement of heating season total off
mode power (P2x) for coil-only split
systems and for blower coil split
systems for which a furnace or a
modular blower is the designated air
mover. Instances of P2x in section
3.13.1.d of appendix M are revised to Px.
Finally, many of the instructions in
the final rule that indicate that a default
cyclic degradation coefficient is to be
used if the tests to determine this value
are not conducted, but erroneously did
E:\FR\FM\18AUR1.SGM
18AUR1
55112
Federal Register / Vol. 81, No. 160 / Thursday, August 18, 2016 / Rules and Regulations
not specify that the default value is to
be used if the value determined using
the test exceeded the default value. 81
FR 36991, 37033 (June 8, 2016). DOE
intended that the default value is to be
used if the value determined using the
test exceeds the default value for the
cyclic degradation coefficient, and is
correcting this omission in this final
rule correction.
II. Need for Correction
As published, the adopted test
procedure text may potentially result in
confusion regarding how to correctly
conduct DOE’s central air conditioners
and heat pumps test procedure.
Because this final rule would simply
correct errors in the regulatory text
without making substantive changes to
the test procedures, the changes
addressed in this document are
technical in nature. Accordingly, DOE
finds that there is good cause under 5
U.S.C. 553(b)(B) to not issue a separate
notice to solicit public comment on the
changes contained in this document.
Issuing a separate notice to solicit
public comment would be
impracticable, unnecessary, and
contrary to the public interest.
III. Procedural Requirements
DOE has concluded that the
determinations made pursuant to the
various procedural requirements
applicable to the June 8, 2016 test
procedure final rule remain unchanged
for this final rule technical correction.
These determinations are set forth in the
June 8, 2016 final rule. 81 FR 36992.

This set of tests is for single-speedcompressor units that do not have a cooling
minimum air volume rate or a cooling
intermediate air volume rate that is different
than the cooling full load air volume rate.
Conduct two steady-state wet coil tests, the
A and B Tests. Use the two optional dry-coil
tests, the steady-state C Test and the cyclic
D Test, to determine the cooling mode cyclic
degradation coefficient, CDc. If the two

SUPPLEMENTARY INFORMATION:
I. Background
On June 8, 2016, DOE's Office of Energy Efficiency and Renewable
Energy published a test procedure final rule in the Federal Register
titled, ``Test Procedures for Central Air Conditioners and Heat Pumps''
(``June 2016 final rule''). 81 FR 36992. Since the publication of that
final rule, it has come to DOE's attention that, due to a technical
oversight, certain portions of the regulatory text adopted in the June
2016 final rule for 10 CFR part 429 and appendix M to subpart B of 10
CFR part 430 (``appendix M'') contained editorial errors.
As part of that final rule, DOE amended 10 CFR 429.16, which
addresses certification of central air conditioners and heat pumps, and
10 CFR 429.70, which addresses alternate efficiency determination
methods. This correction addresses editorial errors in Sec.
429.16(a)(1), (d)(1), (d)(2), and (e)(4). Specifically, at Sec.
429.16(a)(1), DOE included a cross reference to paragraph (c)(2) that
should have referred to paragraph (b)(2)(i). In Sec. 429.16(d)(1) and
(2), DOE mistakenly transposed the words ``less'' and ``greater.'' At
Sec. 429.16(e)(4), DOE erroneously referred to cubic feet per minute
(cfm) instead of cubic feet per minute of standard air (scfm). At Sec.
429.16(e)(4)(viii), DOE failed to remove regulatory text associated
with changes to the test procedure for variable speed heat pumps not
adopted in the June 2016 final rule that had been proposed on November
9, 2015 in a supplementary notice of proposed rulemaking (``November
2015 SNOPR''). 80 FR 69278. In order to remedy these errors, DOE is
issuing this final rule correction to revise the text in these
sections.
In addition, the June 2016 final rule revised appendix M to subpart
B of 10 CFR part 430 (``appendix M''), which specifies the ``Uniform
Test Method for the Measurement the Energy Consumption of Central Air
Conditioners and Heat Pumps.'' This correction also addresses several
editorial errors in appendix M.
In section 3.11.1 of appendix M, ``If using the outdoor air
enthalpy method as the secondary test method,'' DOE erroneously
numbered two subsections with the number ``3.11.1.1.'' The second of
these two is renumbered to ``3.11.1.2.''
In section 4.1 of appendix M, ``Seasonal Energy Efficiency Ratio
(SEER) Calculations,'' DOE erroneously numbered subsection 4.1.3 as
``4.1.2.3,'' which propagated errors in numbering from that point
through the end of section 4.1 and created erroneous cross-references
to these sections. Section 4.1.2.3 is renumbered as section ``4.1.3,''
and the following section numbers through the end of section 4.1 are
renumbered accordingly. Additionally, cross-references to the
renumbered sections are revised.
Sections 2.11 and 3.19 of appendix M contain errors in the
tolerance allowed between temperature measurements. The preamble to the
June 2016 final rule states that the maximum allowable temperature
difference is 2.0[emsp14][deg]F and that it applies to the average
measurements for the test period. 81 FR 36991, 37028 (June 8, 2016). In
section 2.11, DOE erroneously referred to ``maximum difference between
readings'' rather than adding the clarification discussed in the
preamble that ``readings'' referred to the average temperatures
measured during the test period. In section 3.1.9, DOE similarly failed
to include the clarifying information on the tolerance and erroneously
provided a tolerance of 1.5[emsp14][deg]F rather than
2.0[emsp14][deg]F. DOE is correcting section 2.11 accordingly and
correcting 3.1.9 to refer directly to section 2.11 rather than
correcting the provided tolerance.
Tables 8, 9, 15, 16, and 17 of appendix M contained various errors
in testing tolerances for external resistance to airflow, airflow
nozzle pressure difference, and electric voltage. In the preamble of
the June 2016 Final Rule, DOE explained its intention to maintain the
external resistance to airflow tolerance at 0.05 inches of water, to
maintain the airflow nozzle pressure difference tolerance at 2.0%, and
to maintain the electric voltage tolerance at 2.0%. 81 FR 36991, 37036
(June 8, 2016). However, this was not reflected in tables 8, 9, 15, 16
and 17 of appendix M, and the tables are revised to reflect these
corrections.
In section 3.13.1.d of appendix M, P2x was erroneously
printed instead of Px in two instances. This section
provides instructions for measurement of the indoor unit low voltage
power Px, which is later subtracted from the measurement of
heating season total off mode power (P2x) for coil-only
split systems and for blower coil split systems for which a furnace or
a modular blower is the designated air mover. Instances of
P2x in section 3.13.1.d of appendix M are revised to
Px.
Finally, many of the instructions in the final rule that indicate
that a default cyclic degradation coefficient is to be used if the
tests to determine this value are not conducted, but erroneously did
[[Page 55112]]
not specify that the default value is to be used if the value
determined using the test exceeded the default value. 81 FR 36991,
37033 (June 8, 2016). DOE intended that the default value is to be used
if the value determined using the test exceeds the default value for
the cyclic degradation coefficient, and is correcting this omission in
this final rule correction.
II. Need for Correction
As published, the adopted test procedure text may potentially
result in confusion regarding how to correctly conduct DOE's central
air conditioners and heat pumps test procedure.
Because this final rule would simply correct errors in the
regulatory text without making substantive changes to the test
procedures, the changes addressed in this document are technical in
nature. Accordingly, DOE finds that there is good cause under 5 U.S.C.
553(b)(B) to not issue a separate notice to solicit public comment on
the changes contained in this document. Issuing a separate notice to
solicit public comment would be impracticable, unnecessary, and
contrary to the public interest.
III. Procedural Requirements
DOE has concluded that the determinations made pursuant to the
various procedural requirements applicable to the June 8, 2016 test
procedure final rule remain unchanged for this final rule technical
correction. These determinations are set forth in the June 8, 2016
final rule. 81 FR 36992.

3.2.1 Tests for a System Having a Single-Speed Compressor and Fixed
Cooling Air Volume Rate
This set of tests is for single-speed-compressor units that do
not have a cooling minimum air volume rate or a cooling intermediate
air volume rate that is different than the cooling full load air
volume rate. Conduct two steady-state wet coil tests, the A and B
Tests. Use the two optional dry-coil tests, the steady-state C Test
and the cyclic D Test, to determine the cooling mode cyclic
degradation coefficient, CD\c\. If the two optional tests
are conducted but yield a tested CD\c\ that exceeds the
default CD\c\ or if the two optional tests are not
conducted, assign CD\c\ the default value of 0.25 (for
outdoor units with no match) or 0.20 (for all other systems). Table
