(21) Change of employers during
COVID–19 National Emergency. (i) If an
H–2A nonimmigrant who is physically
present in the United States seeks to
change employers during the COVID–19
National Emergency (which began on
March 1, 2020), the prospective new H–
2A employer may file an H–2A petition
on Form I–129, accompanied by a valid
temporary agricultural labor
certification, requesting an extension of
the alien’s stay in the United States. To
be approved under this paragraph
(h)(21), an H–2A petition must be
received no later than August 18, 2020.
If the new petition is approved, the
extension of stay may be granted for the
validity of the approved petition for a
period not to exceed the validity period
of the temporary agricultural labor
certification. Notwithstanding
paragraph (h)(2)(i)(D) of this section and
8 CFR 274a.12(b)(21), an alien in valid
H–2A nonimmigrant status on March 1,
2020, or lawfully obtaining such status
thereafter pursuant to this paragraph
(h)(21), is authorized to begin
employment with the new petitioner
after the petition described in this
paragraph (h)(21) is received by USCIS,
but no earlier than the start date of
employment, indicated in the H–2A
petition. The H–2A worker is authorized
to commence employment with the
petitioner before the petition is
approved and subject to the
requirements of 8 CFR 274a.12(b)(26) for
a period of up to 45 days beginning on
the Received Date on Form I–797
(Notice of Action) or, if the start date of
employment occurs after the I–797
Received Date, 45 days beginning on the
start date of employment indicated in
the H–2A petition. If USCIS adjudicates
the petition prior to the expiration of
this 45-day period and denies the
petition for extension of stay, or if the
petition is withdrawn by the petitioner
before the expiration of the 45-day
period, the employment authorization
associated with the filing of that petition
under 8 CFR 274a.12(b)(26) will
automatically terminate 15 days after
the date of the denial decision or the
date on which the petition is
withdrawn.
(ii) Notwithstanding paragraphs
(h)(5)(viii)(C), (h)(13)(i)(B), and
(h)(15)(ii)(C) of this section, an H–2A
petition seeking an extension of stay,
submitted with a valid temporary
agricultural labor certification, may be
approved on the basis of paragraph
(h)(21)(i) of this section, even if any of

the aliens requested in the H–2A
petition have exhausted the otherwise
applicable 3-year maximum period of
stay in the United States and have not
thereafter been absent from the United
States for an uninterrupted period of 3
months, or if any such aliens would
exceed the 3-year limit as a consequence
of the approval of the extension.
(iii) This paragraph (h)(21) will expire
on August 18, 2020.

Energy.
ACTION: Final rule; correcting
amendments.
AGENCY:
On June 1, 2016, the U.S.
Department of Energy (‘‘DOE’’)
published a final rule adopting test
procedures for portable air conditioners
(‘‘June 2016 final rule’’). A correction
rule was subsequently published on
October 14, 2016 (‘‘October 2016
correction rule’’), to correct
typographical errors in the June 2016
final rule that were included in the
regulatory text. This document corrects
typographical errors introduced in the
October 2016 correction rule, including
missing parentheses and incorrect
variable names. Neither the errors nor
the corrections in this document affect
the substance of the rulemaking or any
of the conclusions reached in support of
the final rule.
DATES: Effective April 20, 2020.

SUPPLEMENTARY INFORMATION:
SUMMARY:
E:\FR\FM\20APR1.SGM
20APR1
21746
Federal Register / Vol. 85, No. 76 / Monday, April 20, 2020 / Rules and Regulations
I. Background
DOE published a final rule in the
Federal Register on June 1, 2016,
establishing test procedures for portable
air conditioners in appendix CC to
subpart B of Title 10 of the Code of
Federal Regulations (CFR) part 430
(‘‘appendix CC’’). 81 FR 35242. On
October 14, 2016, DOE published a
correction rule that revised appendix CC
to correct typographical errors identified
following the publication of the June
2016 final rule. 81 FR 70923. An
additional correction rule was
published on February 21, 2019, to
republish amendments that could not be
incorporated the Code of Federal
Regulations due to inaccurate
amendatory instructions provided in the
June 2016 final rule. 84 FR 5346. DOE
subsequently identified typographical
errors in appendix CC that were
introduced in the October 2016
correction rule. This correction rule
revises appendix CC to correct these
typographical errors.
Specifically, in section 4.1.2 of
appendix CC, DOE is correcting the
following errors: Missing parentheses in
the Qs_95 and Qs_83 equations; extended
underscore and capitalization in the
subscript for the variable cp_wv and
missing underscore for the variable wia_
95 in the Qs_95 equation; and missing
subscripts for the Ql_83 variable in the
Qinfiltration_83 equation. DOE is also
clarifying in the variable list for the Ql_
95 and Ql_83 equations that the ‘‘60’’
value represents the conversion factor
from minutes to hours.
II. Need for Correction
As published, the regulatory text in
the June 2016 final rule as corrected by
the October 2016 and February 2019
correction rules may result in confusion
due to typographical errors in section
4.1.2 of appendix CC. Because this final
rule would simply correct errors in the
text without making substantive
changes in the June 2016 final rule, the
changes addressed in this document are
technical in nature.
III. Procedural Issues and Regulatory
Review
DOE has concluded that the
determinations made pursuant to the
various procedural requirements
applicable to the June 2016 final rule
remain unchanged for this final rule
technical correction. These
determinations are set forth in the June
2016 final rule. 81 FR 35242, 35260.
Pursuant to the Administrative
Procedure Act, 5 U.S.C. 553(b), DOE has
determined there is good cause to find
that notice and prior opportunity for
comment on this rule are unnecessary
and contrary to the public interest.
Neither the errors nor the corrections in
this document affect the substance of
the June 2016 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 that do not change the substance
of the test procedure serves no useful
purpose. Further, this rule correcting
typographical errors makes nonsubstantive changes to the test
procedure. 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.

SUPPLEMENTARY INFORMATION:
[[Page 21746]]
I. Background
DOE published a final rule in the Federal Register on June 1, 2016,
establishing test procedures for portable air conditioners in appendix
CC to subpart B of Title 10 of the Code of Federal Regulations (CFR)
part 430 (``appendix CC''). 81 FR 35242. On October 14, 2016, DOE
published a correction rule that revised appendix CC to correct
typographical errors identified following the publication of the June
2016 final rule. 81 FR 70923. An additional correction rule was
published on February 21, 2019, to republish amendments that could not
be incorporated the Code of Federal Regulations due to inaccurate
amendatory instructions provided in the June 2016 final rule. 84 FR
5346. DOE subsequently identified typographical errors in appendix CC
that were introduced in the October 2016 correction rule. This
correction rule revises appendix CC to correct these typographical
errors.
Specifically, in section 4.1.2 of appendix CC, DOE is correcting
the following errors: Missing parentheses in the Qs_95 and
Qs_83 equations; extended underscore and capitalization in
the subscript for the variable cp_wv and missing underscore
for the variable [omega]ia_95 in the Qs_95
equation; and missing subscripts for the Ql_83 variable in
the Qinfiltration_83 equation. DOE is also clarifying in the
variable list for the Ql_95 and Ql_83 equations
that the ``60'' value represents the conversion factor from minutes to
hours.
II. Need for Correction
As published, the regulatory text in the June 2016 final rule as
corrected by the October 2016 and February 2019 correction rules may
result in confusion due to typographical errors in section 4.1.2 of
appendix CC. Because this final rule would simply correct errors in the
text without making substantive changes in the June 2016 final rule,
the changes addressed in this document are technical in nature.
III. Procedural Issues and Regulatory Review
DOE has concluded that the determinations made pursuant to the
various procedural requirements applicable to the June 2016 final rule
remain unchanged for this final rule technical correction. These
determinations are set forth in the June 2016 final rule. 81 FR 35242,
35260.
Pursuant to the Administrative Procedure Act, 5 U.S.C. 553(b), DOE
has determined there is good cause to find that notice and prior
opportunity for comment on this rule are unnecessary and contrary to
the public interest. Neither the errors nor the corrections in this
document affect the substance of the June 2016 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 that do not change the substance of the test
procedure serves no useful purpose. Further, this rule correcting
typographical errors makes non-substantive changes to the test
procedure. 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.

4.1.2. Infiltration Air Heat Transfer. Measure the heat
contribution from infiltration air for single-duct portable air
conditioners and dual-duct portable air conditioners that draw at
least part of the condenser air from the conditioned space.
Calculate the heat contribution from infiltration air for single-
duct and dual-duct portable air conditioners for both cooling mode
outdoor test conditions, as described in this section. Calculate the
dry air mass flow rate of infiltration air according to the

For single-duct and dual-duct portable air conditioners,
calculate the sensible component of infiltration air heat
