Greenhouse Gas Emissions Standards for Heavy-Duty Vehicles--Phase
3; Correction
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule; correction.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is issuing a
correction to a final rule published in the Federal Register of Monday,
April 22, 2024, which will be effective June 21, 2024. The final rule
established new emission standards for heavy-duty highway vehicles,
along with several amendments for a wide range of highway and nonroad
engines and vehicles. This document corrects inadvertent errors
introduced in preparing the amendatory regulatory text for publication.
These corrections do not include any substantives change to the final
rule.
DATES: This correction is effective June 21, 2024.
DATES: EPA has established a docket for this action under Docket ID No.
EPA-HQ-OAR-2022-0985. Publicly available docket materials are available
either electronically at www.regulations.gov or in hard copy at Air and
Radiation Docket and Information Center, EPA Docket Center, EPA/DC, EPA

SUPPLEMENTARY INFORMATION: EPA is making several corrections for
inadvertent errors in the regulatory text for the final rule:
Two variables in the variable definitions and example of
Eq. 1036.535-1 are formatted improperly in the Federal Register; we are
correcting those variable formats in 40 CFR 1036.535(b)(8).
The equation text of Eq. 1036.545-3 was included in the
signed final rule but is missing in the Federal Register; we are
restoring Eq. 1036.545-3 in 40 CFR 1036.545(f)(3).
[[Page 51235]]
Two variables in the variable definitions of Eq. 1036.545-
11 are formatted improperly in the Federal Register; we are correcting
those variable formats in 40 CFR 1036.545(o)(4)(iii).
Table 1 of paragraph (b)(1) of Sec. 1037.105 incorrectly
presents the tractor vehicle standards in place of the vocational
vehicle standards; we are replacing the published table with the
correct table for the vocational vehicle standards in 40 CFR
1037.105(b)(1).
Table 1 of paragraph (b)(1) of Sec. 1037.106 as published
does not clearly present the heavy-haul standards that apply each model
year; we are replacing the table with an image that more clearly
differentiates heavy-haul standards in 40 CFR 1037.106(b)(1).
Paragraphs (f)(5)(ii) and (iii) of 40 CFR 1065.510 are
published as a single paragraph in the Federal Register; we are adding
a line break to separate the paragraphs.
The equation number for Eq. 1065.602-19 in 40 CFR
1065.602(m)(1)(ii) is placed below the example calculations in the
Federal Register; we are moving the equation number to be directly
below the equation text.
Subscripts within the heading of table 3 to paragraph
(e)(4) of Sec. 1065.656 are improperly formatted in the Federal
Register; we are replacing the table with an image to ensure that the
characters render properly.
The table note reference in the table caption of table 1
to paragraph (a)(1)(ii) of Sec. 1065.750 is improperly formatted in
the publication version; we are replacing the capital ``A'' with a
lowercase ``a'' to match the table note format.
Section 553(b)(B) of the Administrative Procedure Act (APA), 5
U.S.C. 553(b)(B), provides that, when an agency for good cause finds
that public notice and comment procedures are impracticable,
unnecessary, or contrary to the public interest, the agency may issue a
rule without providing notice and an opportunity for public comment.
EPA has determined that there is good cause for making this technical
correction final without prior proposal. Such notice and opportunity
for comment is unnecessary as the technical corrections are for minor
typographical and other non-substantive errors made to the signature
version in preparation for publication.
This final rule is effective June 21, 2024. APA section 553(d)(3),
5 U.S.C. 553(d), provides that final rules shall not become effective
until 30 days after publication in the Federal Register ``except . . .
as otherwise provided by the agency for good cause.'' The purpose of
this provision is to ``give affected parties a reasonable time to
adjust their behavior before the final rule takes effect.'' Omnipoint
Corp. v. Fed. Commc'n Comm'n, 78 F.3d 620, 630 (D.C. Cir. 1996); see
also United States v. Gavrilovic, 551 F.2d 1099, 1104 (8th Cir. 1977)
(quoting legislative history). Thus, in determining whether good cause
exists to waive the 30-day delay, an agency should ``balance the
necessity for immediate implementation against principles of
fundamental fairness which require that all affected persons be
afforded a reasonable amount of time to prepare for the effective date
of its ruling.'' Gavrilovic, 551 F.2d at 1105. EPA has determined that
there is good cause for making this final rule effective less than 30
days after publication in the Federal Register because the technical
corrections are for minor typographical and other non-substantive
errors made to the signature version in preparation for publication,
these corrections will address potential confusion for regulated
entities that could result if these errors introduced during
preparation for publication are not corrected prior to the effective
date of the final rule published in the Federal Register of Monday,
April 22, 2024, and further time is not needed for regulated entities
to prepare for such corrections prior to the effective date given the
nature of the corrections.
For these reasons, the agency finds that good cause exists under
APA section 553(d)(3) to make this rule effective June 21, 2024.
Corrections
In FR Doc. 2024-06809, beginning on page 29440 in the Federal
Register of Monday, April 22, 2024, the following corrections are made:
0
1. On page 29750, beginning in the third column, paragraph (b)(8) of
Sec. 1036.535 is corrected to read as follows:
Sec. 1036.535 [Corrected]
* * * * *
(b) * * *
(8) If you determine fuel-consumption rates using emission
measurements from the raw or diluted exhaust, calculate the mean fuel
mass flow rate, mifuel, for each point in the fuel map using
the following equation:
[GRAPHIC] [TIFF OMITTED] TR17JN24.003
Where:
mifuel = mean fuel mass flow rate for a given fuel map
setpoint, expressed to at least the nearest 0.001 g/s.
MC = molar mass of carbon.
WCmeas = carbon mass fraction of fuel (or mixture of test
fuels) as determined in 40 CFR 1065.655(d), except that you may not
use the default properties in 40 CFR 1065.655(e)(5) to determine
[alpha], [beta], and wC. You may not account for the
contribution to [alpha], [beta], [gamma],and [delta] of diesel
exhaust fluid or other non-fuel fluids injected into the exhaust.
ni = the mean exhaust molar flow rate from which you measured
emissions according to 40 CFR 1065.655.
xCcombdry = the mean concentration of carbon from fuel
and any injected fluids in the exhaust per mole of dry exhaust as
determined in 40 CFR 1065.655(c).
xH2Oexhdry = the mean concentration of H2O in
exhaust per mole of dry exhaust as determined in 40 CFR 1065.655(c).
miCO2DEF = the mean CO2 mass emission rate
resulting from diesel exhaust fluid decomposition as determined in
paragraph (b)(9) of this section. If your engine does not use diesel
exhaust fluid, or if you choose not to perform this correction, set
miCO2DEF equal to 0.
MCO2 = molar mass of carbon dioxide.

(5) Optional declared torques. You may use declared torque instead
of measured torque as follows:
(i) For variable-speed engines you may declare a maximum torque
over the engine operating range. You may use the declared value for
measuring warm high-idle speed as specified in this section.
(ii) For constant-speed engines you may declare a maximum test
torque. You may use the declared value for cycle generation if it is
within (95 to 100)% of the measured value.
(iii) For variable-speed engines, you may declare a nonzero torque
for idle operation that represents in-use operation. For example, if
your engine is connected to a hydrostatic transmission with a minimum
torque even when all the driven hydraulic actuators and motors are
stationary and the engine is at idle, you may use this minimum torque
as the declared value. As another example, if your engine is connected
to a vehicle or machine with accessories, you may use a declared torque
corresponding to operation with those accessories. You may specify a
combination of torque and power as described in paragraph (f)(6) of
this section. Use this option when the idle loads (e.g., vehicle
accessory loads) are best represented as a constant torque on the
primary output shaft. You may use multiple warm idle loads and
associated idle speeds in cycle generation for representative testing.
As an example, see the required deviations for cycle generation in
Sec. 1065.610(d)(3) for improved simulation of idle points for engines
intended primarily for propulsion of a vehicle with an automatic or
manual transmission where that engine is subject to a transient duty
cycle with idle operation.
(iv) For constant-speed engines, you may declare a warm minimum
torque that represents in-use operation. For example, if your engine is
typically connected to a machine that does not operate below a certain
minimum torque, you may use this minimum torque as the declared value
and use it for cycle generation.
