SUPPLEMENTARY INFORMATION:

I. General Discussion

    PHMSA is proposing several changes to Part 171, General 
Information, Regulations, and Definitions, and Part 174, Carriage by 
Rail of Chapter I of Title 49 of the Code of Federal Regulations (CFR). 
These proposed changes would remove or replace various rail 
requirements that are either obsolete, overly burdensome, or conflict 
with other requirements in the HMR. PHMSA does not expect that these 
proposed revisions would have any adverse impact on safety.
    Section 171.7 contains a list of the various documents PHMSA has 
incorporated by reference into the HMR. Section 171.7 also includes a 
table displaying materials that are not incorporated by reference. 
PHMSA is proposing to remove several publications from the table issued 
by the Association of American Railroad's (AAR) Bureau of Explosives 
(BOE), including the Intermodal Loading Guide for Products in Closed 
Trailers and Containers, Pamphlet 6, Pamphlet 6A, Pamphlet 6C, and the 
Emergency Handling of Hazardous Materials in Surface Transportation. 
Many of these publications have not been updated in decades and are no 
longer relevant to the nation's modern supply chain. PHMSA is proposing 
to remove these obsolete publications from the table and to make other 
conforming changes to Sec. Sec.  174.55, 174.101, 174.112, 174.115, and 
174.290 to remove subsequent references to the same publications.
    Section 174.20(a) authorizes a rail carrier to impose local or 
carrier restrictions for hazardous materials when acceptance, 
transportation, or delivery is unusually hazardous. Section 174.20(b) 
also requires a carrier to report these restrictions to the AAR BOE. 
The removal of these reporting requirements was initiated by an AAR 
proposal at the June 2016, Railroad Safety Advisory Committee (RSAC) 
meeting as their recommendation was that the reporting requirement to 
the AAR's BOE was no longer necessary. The final decision to remove and 
reserve this section was approved by consensus vote at the May 25, 
2017, RSAC meeting and offered to PHMSA and Federal Railroad 
Administration (FRA) for consideration. Therefore, PHMSA understands 
these reports to be outdated requirements, but nonetheless welcomes 
input from stakeholders on their current use, if any. PHMSA expects 
removing this section would not adversely impact safety because rail 
carriers would still be able to make a determination that local 
conditions make the acceptance, transportation, or delivery of 
hazardous materials unusually hazardous. This would maintain the 
current level of safety by retaining the railroad's discretion to 
restrict the movement of hazardous materials when a rail line is unsafe 
due to weather, track damage, or other

[[Page 28557]]

reasons that would make the transportation of hazardous materials 
unusually hazardous while reducing reporting burdens.
    Section 174.67 prescribes the requirements for tank car 
transloading. PHMSA is proposing to remove certain outdated and 
unnecessary requirements from Sec.  174.67, including removing the 
references to dirt and cinders in paragraph (b), amending paragraph (d) 
to provide flexibility in protecting open tank cars during 
transloading, and removing paragraph (n) because it is redundant to 
Sec.  174.57. PHMSA expects that these changes would not have any 
adverse impact on safety as transloading has become significantly less 
common since the adoption of Sec.  174.67 and the risks that these 
requirements were meant to mitigate have significantly diminished due 
to technological advances in the rail industry over the last 50 years.

II. Regulatory Analysis and Notices

A. Legal Authority

    This proposed rule is published under the authority of the 
Secretary of Transportation set forth in the Federal Hazardous 
Materials Transportation Laws (49 U.S.C. 5101 et seq.) and delegated to 
the PHMSA Administrator pursuant to 49 CFR 1.97.

B. Executive Orders 12866; Regulatory Planning and Review

    Executive Order (E.O.) 12866 (``Regulatory Planning and 
Review''),\1\ as implemented by DOT Order 2100.6B (``Policies and 
Procedures for Rulemaking''), requires agencies to regulate in the 
``most cost-effective manner,'' to make a ``reasoned determination that 
the benefits of the intended regulation justify its costs,'' and to 
develop regulations that ``impose the least burden on society.'' DOT 
Order 2100.6B specifies that regulations should generally ``not be 
issued unless their benefits are expected to exceed their costs.'' In 
arriving at those conclusions, E.O. 12866 requires that agencies should 
consider ``both quantifiable measures . . . and qualitative measures of 
costs and benefits that are difficult to quantify'' and ``maximize net 
benefits . . . unless a statute requires another regulatory approach.'' 
E.O. 12866 also requires that ``agencies should assess all costs and 
benefits of available regulatory alternatives, including the 
alternative of not regulating.'' DOT Order 2100.6B directs that PHMSA 
and other Operating Administrations must generally choose the ``least 
costly regulatory alternative that achieves the relevant objectives'' 
unless required by law or compelling safety need.
---------------------------------------------------------------------------

    \1\ 58 FR 51735 (Oct. 4, 1993).
---------------------------------------------------------------------------

    E.O. 12866 and DOT Order 2100.6B also require that PHMSA submit 
``significant regulatory actions'' to the Office of Information and 
Regulatory Affairs (OIRA) within the Executive Office of the 
President's Office of Management and Budget (OMB) for review. This NPRM 
is a not significant regulatory action pursuant to E.O. 12866; it also 
has not designated this rule as a ``major rule'' as defined by the 
Congressional Review Act (5 U.S.C. 801 et seq.).
    PHMSA has complied with the requirements in E.O. 12866 as 
implemented by DOT Order 2100.6B and made a preliminary determination 
that this NPRM would result in cost savings by reducing regulatory 
burdens and regulatory uncertainty for the railroad industry by 
removing unnecessary reporting requirements. PHMSA expects those cost 
savings would also result in reduced costs for the public to whom those 
entities generally transfer a portion of their compliance costs.

C. Executive Orders 14192 and 14219

    This proposed rule, if finalized as proposed, is expected to be an 
E.O. 14192 deregulatory action.\2\ PHMSA seeks data that would be 
helpful to generate an estimate of the cost savings from this rule. 
PHMSA's initial estimates are that the total costs of the rule on the 
regulated community would be less than zero. Nor does this proposed 
rule does implicate any of the factors identified in section 2(a) of 
E.O. 14219 indicative of a regulation that is ``unlawful . . . [or] 
that undermine[s] the national interest.'' \3\
---------------------------------------------------------------------------

    \3\ 90 FR 10583 (Feb. 19, 2025).
---------------------------------------------------------------------------

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

    The President has declared in E.O. 14156 (``Declaring a National 
Energy Emergency'') \4\ a national emergency to address the United 
States's inadequate energy development, production, transportation, 
refining, and generation capacity. Similarly, E.O. 14154 (``Unleashing 
American Energy'') \5\ asserts a Federal policy to unleash American 
energy by ensuing access to abundant supplies of reliable, affordable 
energy from (inter alia) the removal of ``undue burden[s]'' on the 
identification, development, or use of domestic energy resources. PHMSA 
preliminary finds this proposed rule is consistent with each of E.O. 
14156 and E.O. 14154. The proposed rule would give railroads relief by 
reducing reporting costs and modernizing safety requirements to remove 
outdated, inefficient methods. PHMSA therefore expects the regulatory 
amendments in this proposed rule would in turn improve railroads' 
ability to provide abundant, reliable, affordable energy products in 
response to residential, commercial, and industrial demand.
---------------------------------------------------------------------------

    \5\ 90 FR 8353 (Jan. 29, 2025).
---------------------------------------------------------------------------

    However, this proposed rule is not a ``significant energy action'' 
under E.O. 13211 (``Actions Concerning Regulations That Significantly 
Affect Energy Supply, Distribution, or Use''),\6\ which requires 
Federal agencies to prepare a Statement of Energy Effects for any 
``significant energy action.'' This proposed rule is not a significant 
action under E.O. 12866, and moreover, it would not have a significant 
adverse effect on supply, distribution, or energy use. OIRA has 
therefore not designated this proposed rule as a significant energy 
action.
---------------------------------------------------------------------------

    \6\ 66 FR 28355 (May 22, 2001).
---------------------------------------------------------------------------

E. Executive Order 13132: Federalism

    PHMSA analyzed this proposed rule in accordance with the principles 
and criteria contained in E.O. 13132 (``Federalism'') \7\ and the 
Presidential Memorandum (``Preemption'') published in the Federal 
Register on May 22, 2009.\8\ E.O. 13132 requires agencies to assure 
meaningful and timely input by State and local officials in the 
development of regulatory policies that may have ``substantial direct 
effects on the States, on the relationship between the National 
Government and the States, or on the distribution of power and 
responsibilities among the various levels of government.'' The Federal 
Hazardous Materials Transportation laws contain an express preemption 
provision at 49 U.S.C. 5125(b) that preempts state, local, and tribal 
requirements on certain covered subjects, unless the non-federal 
requirements are ``substantively the same'' as the federal 
requirements, including the following:
---------------------------------------------------------------------------

    \7\ 64 FR 43255 (Aug. 10, 1999).
    \8\ 74 FR 24693 (May 22, 2009).
---------------------------------------------------------------------------

    (1) The designation, description, and classification of hazardous 
material;
    (2) The packing, repacking, handling, labeling, marking, and 
placarding of hazardous material;
    (3) The preparation, execution, and use of shipping documents 
related to hazardous material and requirements

[[Page 28558]]

related to the number, contents, and placement of those documents;
    (4) The written notification, recording, and reporting of the 
unintentional release in transportation of hazardous material; and
    (5) The design, manufacture, fabrication, inspection, marking, 
maintenance, recondition, repair, or testing of a packaging or 
container represented, marked, certified, or sold as qualified for use 
in transporting hazardous material in commerce.
    This proposed rule addresses covered subject items in section I 
above and would preempt state, local, and Tribal requirements not 
meeting the ``substantively the same'' standard. While the proposed 
rule may operate to preempt some State requirements, it would not 
impose any regulation that has substantial direct effects on the 
States, the relationship between the National Government and the 
States, or the distribution of power and responsibilities among the 
various levels of government. The preemptive effect of the regulatory 
amendments in this proposed rule is limited to the minimum level 
necessary to achieve the objectives of the Federal Hazardous Materials 
Transportation laws. Therefore, the consultation and funding 
requirements of E.O. 13132 do not apply.

F. Regulatory Flexibility Act

    The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires 
Federal agencies to conduct an Initial Regulatory Flexibility Analysis 
(IRFA) for a proposed rule subject to notice-and-comment rulemaking 
under the APA unless the agency head certifies that the proposed rule 
in the rulemaking would not have a significant economic impact on a 
substantial number of small entities. E.O. 13272 (``Proper 
Consideration of Small Entities in Agency Rulemaking'') \9\ obliges 
agencies to establish procedures promoting compliance with the 
Regulatory Flexibility Act. DOT posts its implementing guidance on a 
dedicated web page.\10\ This proposed rule was developed in accordance 
with E.O. 13272 and DOT implementing guidance to ensure compliance with 
the Regulatory Flexibility Act. The proposed rule is expected to reduce 
burdens. Therefore, PHMSA certifies the proposed rule does not have a 
significant impact on a substantial number of small entities.
---------------------------------------------------------------------------

    \9\ 67 FR 53461 (Aug. 16, 2002).
    \10\ DOT, ``Rulemaking Requirements Related to Small Entities,'' 
https://www.transportation.gov/regulations/rulemaking-requirements-concerning-small-entities (last accessed Sept 3, 2024).
---------------------------------------------------------------------------

G. Unfunded Mandates Reform Act of 1995

    The Unfunded Mandates Reform Act (UMRA, 2 U.S.C. 1501 et seq.) 
requires agencies to assess the effects of Federal regulatory actions 
on State, local, and Tribal governments, and the private sector. For 
any proposed or direct final rule that includes a Federal mandate that 
may result in the expenditure by state, local, and Tribal governments, 
in the aggregate of $100 million or more (in 1996 dollars) in any given 
year, the agency must prepare, amongst other things, a written 
statement that qualitatively and quantitatively assesses the costs and 
benefits of the Federal mandate.
    This proposed rule does not impose unfunded mandates under UMRA 
because it does not result in costs of $100 million or more (in 1996 
dollars) per year for either State, local, or Tribal governments, or to 
the private sector.

H. National Environmental Policy Act

    The National Environmental Policy Act (NEPA, 42 U.S.C. 4321 et 
seq.) requires that Federal agencies assess and consider the impact of 
major Federal actions on the human and natural environment.
    PHMSA analyzed this proposed rule in accordance with NEPA and has 
preliminarily determined that the rulemaking would not adversely affect 
safety and therefore would not significantly affect the quality of the 
human and natural environment. The public is invited to comment on the 
impact of the proposed action.

I. Executive Order 13175

    PHMSA analyzed this proposed rule according to the principles and 
criteria in E.O. 13175 (``Consultation and Coordination with Indian 
Tribal Governments'') \11\ and DOT Order 5301.1A (``Department of 
Transportation Tribal Consultation Policies and Procedures''). E.O. 
13175 requires agencies to assure meaningful and timely input from 
Tribal government representatives in the development of rules that 
significantly or uniquely affect Tribal communities by imposing 
``substantial direct compliance costs'' or ``substantial direct 
effects'' on such communities or the relationship or distribution of 
power between the Federal government and Tribes.
---------------------------------------------------------------------------

    \11\ 65 FR 67249 (Nov. 9, 2000).
---------------------------------------------------------------------------

    PHMSA assessed the impact of the proposed rule and determined that 
it would not significantly or uniquely affect Tribal communities or 
Indian Tribal governments. The rulemaking's regulatory amendments have 
a broad, national scope; therefore, this proposed rule would not 
significantly or uniquely affect Tribal communities, much less impose 
substantial compliance costs on Native American Tribal governments or 
mandate Tribal action. For these reasons, PHMSA has concluded that the 
funding and consultation requirements of E.O. 13175 and DOT Order 
5301.1A do not apply.

J. Paperwork Reduction Act

    The Paperwork Reduction Act (44 U.S.C. 3501 et seq.) and its 
implementing regulations at 5 CFR 1320.8(d) requires that PHMSA provide 
interested members of the public and affected agencies with an 
opportunity to comment on information collection and recordkeeping 
requests.
    PHMSA has analyzed this NPRM in accordance with the Paperwork 
Reduction Act. PHMSA proposes to revise the approved information 
collections under the following OMB Control Numbers: OMB Control No. 
2137-0559, ``Rail Carrier and Tank Car Tanks Requirements, Rail Tank 
Car Tanks--Transportation of Hazardous Materials by Rail.''
    This NPRM proposes to remove Sec.  174.20(b), which requires 
reporting to the AAR BOE regarding any restrictions over any portion of 
its lines. PHMSA currently accounts for 34 offerors submitting 1.5 
reports a year. Each report takes 20 minutes resulting in a reduction 
of 17 hours of annual burden.
    PHMSA specifically requests comments on the information collection 
and recordkeeping burdens associated with developing, implementing, and 
maintaining these requirements for approval under this NPRM. Address 
written comments to the Dockets Unit as identified in the ADDRESSES 
section of this NPRM. PHMSA must receive comments regarding information 
collection burdens prior to the close of the comment period identified 
in the DATES section of this NPRM. Notwithstanding any other provision 
of law, no person is required to respond to a collection of information 
unless such collection displays a valid OMB control number.
    Please direct your requests for a copy of this information 
collection to Steven Andrews, Office of Hazardous Materials Standards 
(PHH-12), Pipeline and Hazardous Materials Safety Administration, 1200 
New Jersey Avenue SE, 2nd Floor, Washington, DC 20590-0001.

[[Page 28559]]

K. Executive Order 13609 and International Trade Analysis

    E.O. 13609 (``Promoting International Regulatory Cooperation'') 
\12\ requires agencies consider whether the impacts associated with 
significant variations between domestic and international regulatory 
approaches are unnecessary or may impair the 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.
---------------------------------------------------------------------------

    \12\ 77 FR 26413 (May 4, 2012).
---------------------------------------------------------------------------

    Similarly, the Trade Agreements Act of 1979 (Pub. L. 96-39), as 
amended by the Uruguay Round Agreements Act (Pub. L. 103-465), 
prohibits Federal agencies from establishing any standards or engaging 
in related activities that create unnecessary obstacles to the foreign 
commerce of the United States. For purposes of these requirements, 
Federal agencies may participate in the establishment of international 
standards, so long as the standards have a legitimate domestic 
objective, such as providing for safety, and do not operate to exclude 
imports that meet this objective. The statute also requires 
consideration of international standards and, where appropriate, that 
they be the basis for U.S. standards.
    PHMSA engages with international standards setting bodies to 
protect the safety of the American public. PHMSA has assessed the 
effects of the proposed rule and has determined that its regulatory 
amendments would not cause unnecessary obstacles to foreign trade.

L. Cybersecurity and Executive Order 14028

    E.O. 14028 (``Improving the Nation's Cybersecurity'') \13\ directed 
the Federal government to improve its efforts to identify, deter, and 
respond to ``persistent and increasingly sophisticated malicious cyber 
campaigns.'' PHMSA has considered the effects of the proposed rule and 
has determined that its regulatory amendments would not materially 
affect the cybersecurity risk profile for affected entities.
