Federal Register / Vol. 86, No. 229 / Thursday, December 2, 2021 / Rules and Regulations
in codifying this definition in section 1.2 of appendix M1, DOE inadvertently omitted the word minimum when referring to compressor speed at 47 F.
This document adds the word minimum to the definition of minimum-speed-limiting variable-speed heat pump to reflect the intent established by the January 2017 Final Rule.

M. Cross-Reference in Section 3.1.4.7 of Appendix M1
The January 2017 Final Rule established provisions in section 3.1.4.7
of appendix M1 for determining the heating nominal air volume rate to be used in HSPF2 testing. This section omitted a period and erroneously crossreferences section 3.14.6 for adjusting airflowsection 3.1.4.6 is the proper cross-reference. This document corrects these errors.
N. Missing Footnote in Table 14 of Appendix M1
Compressor speeds for variable-speed compressor systems are specified in Table 14 in section 3.6.4 of appendices M and M1. These sections are supposed to include footnotes that specify the Heating Full compressor speed at different outdoor temperature test conditions for systems containing a variable-speed compressor. However, at the optional H42 heating test condition 5 F outdoor temperature in appendix M1, the footnote is missing. There is no H42 test condition for variable-speed heat pumps in appendix M so no footnote is required. For all other test conditions that utilize a full compressor speed, Table 14 to appendix M1 includes footnotes describing the meaning of full compressor speed in the context of each test condition. To specify the H42 compressor speed for variable-speed heat pumps, a footnote is being added to Table 14 in appendix M1
to specify that the Heating Full speed refers to the maximum speed that the systems controls would operate the compressor in normal operation at 5 F
ambient temperature.
This correction is consistent with the discussion provided in the August 24, 2016 supplemental notice of proposed rulemaking SNOPR, in which DOE
stated that the full-speed compressor operation for variable-speed heat pumps could be very different at 5 F than it is at 17 F, thus an extrapolation of performance below 5 F using the 17 F
compressor speed trend between 17 F
and 5 F is not appropriate. 81 FR

compressor speed for the heating test conditions except for the optional H42
heating test condition. 82 FR 58164, 58238. Comment was not received on the appropriate compressor speed at the 5 F condition, and the erroneous omission of the footnote was carried over into the final rule, which adopted the proposal in the August 2016
SNOPR. 82 FR 1426, 1459, 1560. This correction also aligns with current industry test procedures for CAC/HPs AHRI 210/240 2023 which includes a footnote in the test conditions table for variable-speed heat pumps specifying that the full compressor speed to be used at the 5 F heating test condition is the maximum speed the system controls would operate the compressor at 5 F ambient temperature.

DOE has also concluded that the determinations made pursuant to the various regulatory review requirements applicable to the January 2017 final rule remain unchanged for this final rule technical correction. These determinations are set forth in the January 2017 final rule. 84 FR 1426, 14631468.

O. Reference to EER in Section 4.1.4.2
of Appendix M1

Administrative practice and procedure, Confidential business information, Energy conservation, Household appliances, Imports, Incorporation by reference, Intergovernmental relations, Small businesses.

Section 4.1.4.2 of appendix M1
specifies several equations in which variations of the EER metric are used.
One of these equations contains the term EERk=2. In the where statement following the equation, which defines each symbol used in the equation, EERk=2 is erroneously referred to as EER2k=2. This document corrects this error by referring instead to EERk=2.
P. Extraneous Symbols in Section 4.1.3.2 of Appendix M1
The title of section 4.1.3.2 of appendix M1 contains extraneous
symbols preceding the terms BLTj and Qck=2Tj. This document removes these extraneous symbols, consistent with the analogous terms in section 4.1.3.2 of appendix M.
III. Procedural Issues and Regulatory Review Pursuant to the Administrative Procedure Act, 5 U.S.C. 553b, DOE has determined there is good cause to find that prior notice and opportunity for public comment on the changes contained in this document are impracticable, unnecessary, or contrary to the public interest. Neither the errors nor the corrections in this document affect the substance of the January 2017
Final Rule or any of the conclusions reached in support of the final rule.
Providing prior notice and an opportunity for public comment on correcting objective, typographical errors and omissions that do not change the substance of the test procedure serves no useful purpose. As such, this rule is similarly not subject to the 30day delay in effective date requirement of 5 U.S.C. 553d otherwise applicable to rules that make substantive changes.
