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.

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 
4 specifies test conditions for these four tests.

a two-capacity heat pump locks out low capacity operation at lower 
outdoor temperatures, conduct the high temperature cyclic test 
(H1C2) to determine the high-capacity heating mode 
cyclic-degradation coefficient, CD\h\ (k=2). If this 
optional test at high capacity is conducted but yields a tested 
CD\h\ (k = 2) that exceeds the default CD\h\ 
(k = 2) or if the optional test is not conducted, assign 
CD\h\ the default value. The default CD\h\ 
(k=2) is the same value as determined or assigned for the low-
capacity cyclic-degradation coefficient, CD\h\ [or 
equivalently, CD\h\ (k=1)]. Table 12 specifies test
