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. </SUM> <EFFDATE> <HD SOURCE="HED">DATES:</HD> This correction is effective June 21, 2024. </EFFDATE> <EFFDATE> <HD SOURCE="HED">DATES:</HD> 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 <E T="03">www.regulations.gov</E> or in hard copy at Air and Radiation Docket and Information Center, EPA Docket Center, EPA/DC, EPA WJC West Building, 1301 Constitution Ave. NW, Room 3334, Washington, DC. </EFFDATE> <FURINF> <HD SOURCE="HED">FOR FURTHER INFORMATION CONTACT:</HD> Jessica Brakora, Assessment and Standards Division, Office of Transportation and Air Quality, Environmental Protection Agency, 2000 Traverwood Drive, Ann Arbor, MI 48105; telephone number: (734) 214-4936; email address: <E T="03">Brakora.Jessica@epa.gov.</E> </FURINF> <SUPLINF> <HD SOURCE="HED">SUPPLEMENTARY INFORMATION:</HD> 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 <E T="04">Federal Register</E> ; 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 <E T="04">Federal Register</E> ; we are restoring Eq. 1036.545-3 in 40 CFR 1036.545(f)(3). • Two variables in the variable definitions of Eq. 1036.545-11 are formatted improperly in the <E T="04">Federal Register</E> ; we are correcting those variable formats in 40 CFR 1036.545(o)(4)(iii). • Table 1 of paragraph (b)(1) of § 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 § 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 <E T="04">Federal Register</E> ; 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 <E T="04">Federal Register</E> ; 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 § 1065.656 are improperly formatted in the <E T="04">Federal Register</E> ; 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 § 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 <E T="04">Federal Register</E> “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.” <E T="03">Omnipoint Corp.</E> v. <E T="03">Fed. Commc'n Comm'n,</E> 78 F.3d 620, 630 (D.C. Cir. 1996); see also <E T="03">United States</E> v. <E T="03">Gavrilovic,</E> 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.” <E T="03">Gavrilovic,</E> 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 <E T="04">Federal Register</E> 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 <E T="04">Federal Register</E> 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. <HD SOURCE="HD1">Corrections</HD> In FR Doc. 2024-06809, beginning on page 29440 in the <E T="04">Federal Register</E> of Monday, April 22, 2024, the following corrections are made: <REGTEXT TITLE="40" PART="1036"> 1.
