SUPPLEMENTARY INFORMATION: 

I. Background

    On July 24, 2020, PHMSA, in consultation with the Federal Railroad 
Administration (FRA) issued a final rule to amend the Hazardous 
Materials Regulations (HMR) to authorize the transportation of LNG in a 
new DOT-113C120W9 tank car and adopted additional operational controls 
for the safe movement of LNG by rail, effective as of August 24, 2020 
(LNG by Rail Rule).\1\ On August 18, 2020, several stakeholder groups 
filed petitions for judicial review of the LNG by Rail Rule. The 
petitioners challenged the legality of PHMSA's action on various 
grounds, including for failing to comply with the National 
Environmental Policy Act (NEPA), 42 U.S.C. 4321 et seq. The United 
States Court of Appeals for the District of Columbia Circuit (D.C. 
Circuit) later consolidated each of the petitions into a single case 
captioned as Sierra Club, et al. v. DOT, et al. (Case No. 20-1317).\2\
---------------------------------------------------------------------------

    \1\ PHMSA, Hazardous Materials: Final Rule--Liquefied Natural 
Gas by Rail, 85 FR 44994 (July 24, 2020) (the ``July 2020 final 
rule''). The design of the DOT-113C120W9 tank car included enhanced 
safety features, such as a thicker, stronger outer tank.
    \2\ Sierra Club, et al. v. U.S. Department of Transportation, 
Case No. 20-1317 (D.C. Cir. filed Aug. 18, 2020) (consolidated with 
Nos. 20-1318, 20-1431, & 21-1009).
---------------------------------------------------------------------------

    On January 17, 2025, the D.C. Circuit issued a decision on the 
merits of the consolidated petitions.\3\ The D.C. Circuit held that 
PHMSA violated NEPA by failing to prepare an environmental impact 
statement during the rulemaking process. Accordingly, the D.C. Circuit 
vacated the LNG by Rail Rule in its entirety and remanded the matter to 
PHMSA for further proceedings.
---------------------------------------------------------------------------

    \3\ Sierra Club, et al. v. DOT, et al., Case No. 20-1317, 125 
F.4th 1170 (D.C. Cir. 2025).
---------------------------------------------------------------------------

II. Amendments

    PHMSA is adopting conforming amendments to the HMR to address the 
D.C. Circuit's decision in Sierra Club, et al. v. DOT, et al. (Case No. 
20-1317) (Jan. 17, 2025). These conforming amendments are intended to 
restore the text of the HMR to the version that existed prior to the 
effective date of the LNG by Rail Rule. No other regulatory changes are 
being adopted. Accordingly, the text of the following sections will 
revert to the version in effect prior to August 24, 2020: 49 CFR 
172.101, 172.102, 172.820, 173.319, 179.400-5, and 179.400-8. The text 
of sections that did not exist prior to the LNG by Rail Rule, including 
Sec. Sec.  174.200(d), 179.400-26, and 180.515(d), will be deleted in 
its entirety.
    These conforming amendments do not affect the provisions in the HMR 
that authorize the transportation of LNG by highway, vessel, or by rail 
in UN T75 portable tanks. Nor do the conforming amendments prohibit 
interested stakeholders from seeking a special permit to authorize the 
transportation of LNG in rail tank cars in appropriate cases, or from 
using DOT-113C120W9 specification rail tank cars to transport hazardous 
materials in circumstances where that is already permitted under the 
HMR. PHMSA remains committed to facilitating the safe, reliable, and 
efficient transportation of LNG by rail and to expanding the use of 
DOT-113C120W9 specification rail tank cars in transporting other 
hazardous materials.
    PHMSA further notes that it recently issued an Advance Notice of 
Proposed Rulemaking (ANPRM), titled ``Hazardous Materials: Mandatory 
Regulatory Reviews to Unleash American Energy and Improve Government 
Efficiency,'' in a separate rulemaking docket.\4\ That ANPRM solicits 
stakeholder feedback on opportunities to repeal or amend any provisions 
in the HMR that place an undue burden on the identification, 
development, and use of domestic energy resources consistent with 
President Trump's recent directive in E.O. 14154 (``Unleashing American 
Energy'' \5\). The ANPRM also specifically requests information 
regarding potential industry demand to transport LNG and other 
cryogenic liquids by rail tank car. PHMSA encourages any stakeholders 
who are interested in advancing the transportation of LNG and other 
hazardous materials by rail to participate in that proceeding. PHMSA is 
aware of at least one tank car manufacturer that has produced tank cars 
built to the DOT-113C120W9 specification for use with non-LNG cryogenic 
materials. This notice of conforming amendments removes the DOT-
113C120W9 specification from the HMR. PHMSA notes that stenciling of 
those and other tank cars must, pursuant to Sec.  179.22(a), reflect 
current HMR tank car specifications.

III. Regulatory Analyses and Notices

A. Statutory/Legal Authority and Good Cause for Immediate Adoption 
Without Prior Notice and Comment

    Statutory authority for this final rule is provided by the 
Hazardous Materials Transportation Act (HMTA, 49 U.S.C. 5101 et seq.). 
Section 5103(b) of the HMTA authorizes the Secretary of Transportation 
to ``prescribe regulations for the safe transportation, including 
security, of hazardous materials in intrastate, interstate, and foreign 
commerce.'' Id. The Secretary has delegated his rulemaking authority 
under the HMTA to the PHMSA Administrator at 49 CFR 1.97(b).
    PHMSA has good cause to issue this final rule without providing 
notice and comment pursuant to Sec.  553(b)(B) of the Administrative 
Procedure Act (APA, 5 U.S.C. 551 et seq.). The final rule contains 
conforming amendments required by the D.C. Circuit's vacatur of

[[Page 26456]]

the LNG by Rail Rule.\6\ Because this action is compelled by the D.C. 
Circuit decision, PHMSA finds that notice and opportunity for public 
comment are unnecessary under Sec.  553(b)(B) of the APA.
---------------------------------------------------------------------------

    \6\ EME Homer City Generation, LP v. EPA, 795 F.3d 118, 134-35 
(D.C. Cir. 2015) (internal quotations omitted).
---------------------------------------------------------------------------

    PHMSA also finds good cause for making these conforming amendments 
immediately effective. Section 553(d)(3) of the APA provides that a 
rule should take effect not less than 30 days after publication in the 
Federal Register, except when a rule relieves a restriction or when 
good cause is found by the agency and published within the rule 
allowing for earlier effect.\7\ Good cause exists for the immediate 
effect of these conforming amendments because the provisions of the HMR 
being removed no longer have the force and effect of law, and operators 
and the public will benefit from accurate regulatory text reflecting 
the current regulatory environment.\8\ No additional time is necessary 
to conform operator behavior. PHMSA previously suspended the LNG by 
Rail Rule,\9\ and no operators have been transporting LNG by rail tank 
car pursuant to that final rule.

June 30, 2025).
---------------------------------------------------------------------------

B. Executive Order 12866 and Regulatory Planning and Review

    This notice has been evaluated in accordance with E.O. 12866 
(``Regulatory Planning and Review'') \10\ and DOT Order 2100.6B 
(``Rulemaking and Guidance Procedures'') and is considered not 
significant. Therefore, this notice has not been reviewed by the Office 
of Management and Budget (OMB). In addition, this rule is not an E.O. 
14192 regulatory action because this rule is not significant under E.O. 
12866.\11\ As the conforming amendments in the notice merely reflect 
the current state of the regulations following judicial review, PHMSA 
finds that the conforming amendments impose no incremental compliance 
costs, nor do they adversely impair safety.

    \11\ 90 FR 9065 (Feb. 6, 2025).
---------------------------------------------------------------------------

C. Executive Order 13132

    PHMSA has analyzed this notice in accordance with the principles 
and criteria contained in E.O. 13132 (``Federalism'') and finds there 
are no federalism implications from this final rule.\12\
---------------------------------------------------------------------------

    \12\ 64 FR 43255 (Aug. 10, 1999).
---------------------------------------------------------------------------

D. Executive Order 13175

    This document was analyzed in accordance with the principles and 
criteria contained in E.O. 13175 (``Consultation and Coordination with 
Indian Tribal Governments'') \13\ and DOT Order 5301.1A (``Department 
of Transportation Tribal Consultation Policies and Procedures''). 
Because none of the amendments in this notice have tribal implications 
or impose substantial direct compliance costs on Indian tribal 
governments, the funding and consultation requirements of E.O. 13175 do 
not apply.
---------------------------------------------------------------------------

    \13\ 65 FR 67249 (Nov. 6, 2000).
---------------------------------------------------------------------------

E. Regulatory Flexibility Act and Executive Order 13272

    The analytical requirements of the Regulatory Flexibility Act, as 
amended by the Small Business Regulatory Flexibility Fairness Act of 
1996 (RFA, 5 U.S.C. 601 et seq.), do not apply when the agency finds 
good cause under the APA to adopt a rule without prior notice and 
comment.\14\ Because PHMSA has ``good cause'' under the APA to forego 
comment on the amendments herein, no RFA analysis is required.
---------------------------------------------------------------------------

    \14\ See 15 U.S.C. 603-604. See also Small Business 
Administration, ``A Guide for Government Agencies: How to Comply 
with the Regulatory Flexibility Act'' 55 (2017).
---------------------------------------------------------------------------

F. Paperwork Reduction Act

    Under the Paperwork Reduction Act of 1995 (Pub. L. 96-511, codified 
at 44 U.S.C. 3501 et seq.), no individual is required to respond to an 
information collection unless it has been approved by OMB and displays 
a valid OMB control number. Pursuant to 44 U.S.C. 3506(c)(2)(B) and 5 
CFR 1320.8(d), PHMSA must provide interested members of the public and 
affected agencies an opportunity to comment on information collection 
and recordkeeping requests.
    PHMSA has analyzed this rulemaking in accordance with the Paperwork 
Reduction Act. As detailed in the LNG by Rail Rule, Section V.C., 
``Section 172.820,'' PHMSA previously required any rail carrier 
transporting a tank car quantity of UN1972 (Methane, refrigerated 
liquid (cryogenic liquid) or Natural Gas, refrigerated liquid 
(cryogenic liquid, with high methane content)) to comply with 
additional safety and security planning requirements for transportation 
by rail. Following the publication of the LNG by Rail Rule, PHMSA 
published both a 60-day and 30-day notice and comment period to provide 
an opportunity for public comment on the estimated increased reporting 
burden. PHMSA did not receive comments on either notice, and the 
reporting requirement was subsequently approved by OMB.
    However, following the judicial vacatur of the LNG by Rail Rule, 
the reporting requirements are no longer necessary. As a result, PHMSA 
will submit a withdrawal of the information collection requirements to 
OMB under OMB Control Number 2137-0612, ``Hazardous Materials Security 
Plans,'' to reflect the removal of this burden.

G. Unfunded Mandates Reform Act of 1995

    PHMSA analyzed the amendments in this notice pursuant to the 
Unfunded Mandates Reform Act of 1995 (UMRA, 2 U.S.C. 1501, et seq.) and 
determined that the amendments do not impose enforceable duties of $100 
million or more (or $169 million adjusted for inflation) in any given 
year, on state, local, or tribal governments, or on the private sector. 
Because the amendments impose no new incremental compliance costs 
beyond those already assessed in the LNG by Rail Rule, PHMSA's earlier 
UMRA analysis need not be changed.

H. National Environmental Policy Act

    The National Environmental Policy Act of 1969 (NEPA, 42 U.S.C. 
4321, et seq.) requires Federal agencies to prepare a detailed 
statement on major Federal actions significantly affecting the quality 
of the human environment. PHMSA has determined that the amendments in 
this document simply reflect the LNG by Rail Rule as vacated by 
judicial review and do not require further NEPA analysis.

I. Privacy Act Statement

    In accordance with 5 U.S.C. 553(c), the DOT solicits comments from 
the public to inform its rulemaking process. The DOT posts these 
comments, without edit, including any personal information the 
commenter provided, to www.regulations.gov, as described in the systems 
of records notice (DOT/ALL-14 FDMS), which can be reviewed at 
www.dot.gov/privacy.

J. Executive Order 13609 and International Trade Analysis

    Under Executive Order 13609 (``Promoting International Regulatory 
Cooperation''),\15\ agencies must consider whether the impacts 
associated with significant variations between domestic and 
international regulatory approaches are unnecessary or may impair the

[[Page 26457]]

ability of American business to export and compete internationally. In 
meeting shared challenges involving health, safety, labor, security, 
environmental, and other issues, international regulatory cooperation 
can identify approaches that are at least as protective as those that 
are or would be adopted in the absence of such cooperation. 
International regulatory cooperation can also reduce, eliminate, or 
prevent unnecessary differences in regulatory requirements. The 
conforming amendments to the LNG by Rail Rule in this notice are 
required by the D.C. Circuit's vacatur of the LNG by Rail Rule and do 
not impact international trade.

    \15\ 77 FR 26413 (May 4, 2012).
---------------------------------------------------------------------------

K. Energy-Related Executive Orders 13211, 14154, and 14156

    E.O. 13211 (``Actions Concerning Regulations That Significantly 
Affect Energy Supply, Distribution, or Use'') \16\ requires Federal 
agencies to prepare a Statement of Energy Effects for any ``significant 
energy action.'' Under the executive order, a ``significant energy 
action'' is defined as any action by an agency (normally published in 
the Federal Register) that promulgates, or is expected to lead to the 
promulgation of, a final rule that (1)(i) is a significant regulatory 
action under Executive Order 12866 or any successor order and (ii) is 
likely to have a significant adverse effect on the supply, 
distribution, or use of energy (including a shortfall in supply, price 
increases, and increased use of foreign supplies); or (2) is designated 
by the Administrator of the Office of Information and Regulatory 
Affairs (OIRA) as a significant energy action. These conforming 
amendments to the LNG by Rail Rule set forth in this Notice are not a 
``significant energy action'' under E.O. 13211, as they are not a 
significant regulatory action, and they are not likely to have a 
significant adverse effect on supply, distribution, or use of energy.
---------------------------------------------------------------------------

    \16\ 66 FR 28355 (May 18, 2001).
---------------------------------------------------------------------------

    These conforming amendments are also not a significant regulatory 
action under E.O. 12866 and are therefore not likely to have a 
significant adverse effect on the supply, distribution, or use of 
energy for purposes of the requirements of E.O. 14154 (``Unleashing 
American Energy'') \17\ and E.O. 14156 (``Declaring a National Energy 
Emergency'').\18\ That said, PHMSA has issued, in a separate rulemaking 
docket, an Advance Notice of Proposed Rulemaking (ANPRM) titled 
``Hazardous Materials: Mandatory Regulatory Reviews to Unleash American 
Energy and Improve Government Efficiency.'' \19\ That ANPRM solicits 
stakeholder feedback on opportunities to repeal or amend HMR provisions 
placing an undue burden on the identification, development, and use of 
domestic energy resources as contemplated by E.O. 14154. The ANPRM also 
specifically requests information regarding potential industry demand 
to transport LNG and other cryogenic liquids by rail tank car.
