I. General Discussion
PHMSA is proposing to revise 49 CFR 172.315(a)(2) to allow for a
reduced sized limited quantity marking (i.e., a shipping label) for
certain shipments of hazardous materials. PHMSA is also proposing to
revise Sec. 173.25(a)(6) to specifically state that this marking is
not authorized on overpacks. PHMSA has made a preliminary determination
that the current requirements in these regulations impose an undue
burden on limited quantity shipments of hazardous materials. This NPRM,
if finalized, would give affected entities regulatory flexibility by
allowing a limited quantity marking to be used on certain packages.
PHMSA expects that the proposed amendments would provide shippers and
carriers of hazardous materials the ability to transport abundant,
reliable, and affordable consumer products in response to residential,
commercial, and industrial demand.
A ``limited quantity'' of a hazardous material is defined in Sec.
171.8 as the maximum amount of a hazardous material for which there is
a specific labeling or packaging exception. Currently, Sec. 172.315
specifies the marking requirements for limited quantities of hazardous
materials, with paragraph (a)(2) of this section detailing the minimum
size requirements. On January 17, 2024, PHMSA received a petition for
rulemaking (P-1778 \1\) from the Council of Safe Transportation of
Hazardous Articles (COSTHA) requesting the incorporation of Department
of Transportation (DOT) special permit (SP) 21015 into the Hazardous
Materials Regulations (HMR). COSTHA requested the modification of Sec.
172.315(a)(2) to allow for the transportation in commerce of packages
containing limited quantities of hazardous materials with a reduced
size limited quantity marking placed on the package shipping label.
COSTHA noted in its petition that it was unaware of any incidents that
occurred involving DOT-SP 21015, and that its incorporation into the
HMR would
[[Page 28572]]
reduce industry burdens and facilitate compliant processes and
preparation of lower risk hazardous materials. PHMSA responded to this
petition on July 18, 2024, and determined that the proposed amendment
of Sec. 172.315(a)(2) warranted further consideration.
---------------------------------------------------------------------------
\1\ P-1778, Council on the Safe Transportation of Hazardous
Articles (COSTHA)--<a href="https://www.regulations.gov/docket/PHMSA-2024-0002/document">https://www.regulations.gov/docket/PHMSA-2024-0002/document</a>.
---------------------------------------------------------------------------
PHMSA is not aware of any safety concerns related to the
incorporation of DOT-SP 21015 into the HMR and agrees with the
petitioner that doing so would reduce unnecessary compliance burdens;
specifically, by eliminating the need to apply for a special permit in
accordance with Sec. 107.105, to seek party status in accordance with
Sec. 107.107, and to request a renewal in accordance with Sec.
107.109. Incorporating DOT-SP 21015 into the HMR would also allow
offerors of limited quantities shipments to use a consolidated marking
on the shipping label, eliminating the need for a separate limited
quantity label.
For these reasons, PHMSA is proposing to revise Sec. 172.315 to
allow for a reduced size limited quantity marking that is also capable
of electronically communicating to carriers that the package contains
hazardous materials shipped under a limited quantity exception and the
authorized modes of transportation. PHMSA is also proposing to revise
Sec. 173.25(a)(6) to specifically state that the reduced sized limited
quantity mark is not authorized on overpacks. PHMSA does not expect
these revisions to have any adverse impact on safety.
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''),\2\ 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.
---------------------------------------------------------------------------
\2\ 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
proposed rule 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 proposed rule will result in cost savings by reducing
regulatory burdens and regulatory uncertainty for hazardous materials
shippers and carriers. The proposed rule would eliminate the need for a
separate limited quantity label, as the hazard communication
information would be embedded in the shipping label, producing cost
savings for the transportation industry and 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.\3\ 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 will 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.'' \4\
---------------------------------------------------------------------------
\3\ 90 FR 9065 (Jan. 31, 2025).
\4\ 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'') \5\ 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'') \6\ 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 such
as PHMSA-jurisdictional shippers and carriers of hazardous materials.
PHMSA preliminarily finds this proposed rule is consistent with each of
E.O. 14156 and E.O. 14154 because it will not impose any burden on the
transportation of energy or energy-related products.
---------------------------------------------------------------------------
\5\ 90 FR 8353 (Jan. 29, 2025).
\6\ 90 FR 8353 (Jan. 29, 2025).
---------------------------------------------------------------------------
This proposed rule is not a ``significant energy action'' under
E.O. 13211 (``Actions Concerning Regulations That Significantly Affect
Energy Supply, Distribution, or Use''),\7\ which requires Federal
agencies to prepare a Statement of Energy Effects for any ``significant
energy action.'' Because this proposed rule is not a significant action
under E.O. 12866, it will not have a significant adverse effect on
supply, distribution, or energy use; and OIRA has therefore not
designated this proposed rule as a significant energy action.
Therefore, the consultation and funding requirements of E.O. 13132 do
not apply.
---------------------------------------------------------------------------
\7\ 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'') \8\ and the
Presidential Memorandum (``Preemption'') published in the Federal
Register on May 22, 2009.\9\ 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
[[Page 28573]]
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:
---------------------------------------------------------------------------
\8\ 64 FR 43255 (Aug. 10, 1999).
\9\ 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 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 paragraph 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 will not have a significant economic impact on a
substantial number of small entities. E.O. 13272 (``Proper
Consideration of Small Entities in Agency Rulemaking'') \10\ obliges
agencies to establish procedures promoting compliance with the
Regulatory Flexibility Act. DOT posts its implementing guidance on a
dedicated web page.\11\ 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.
---------------------------------------------------------------------------
\10\ 67 FR 53461 (Aug. 16, 2002).
\11\ DOT, ``Rulemaking Requirements Related to Small Entities,''
<a href="https://www.transportation.gov/regulations/rulemaking-requirements-concerning-small-entities">https://www.transportation.gov/regulations/rulemaking-requirements-concerning-small-entities</a> (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 will not adversely affect
safety and therefore will not significantly affect the quality of the
human and natural environment.
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'') \12\ 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.
---------------------------------------------------------------------------
\12\ 65 FR 67249 (Nov. 9, 2000).
---------------------------------------------------------------------------
PHMSA assessed the impact of the proposed rule and determined that
it will 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 will 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. This rulemaking will not create, amend, or rescind any
existing information collections. However, this rulemaking eliminates
the need for persons to renew a special permit, resulting in a decrease
in paperwork burden for special permit holders. PHMSA estimates the
reduction in information collection burden as follows:
OMB Control No. 2137-0051: Rulemaking, Special Permits, and
Preemption Requirements.
Decrease in Annual Number of Respondents: 8.
Decrease in Annual Responses: 8.
Decrease in Annual Burden Hours: 12.
Decrease in Annual Burden Cost: $0.
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 Office of
[[Page 28574]]
Management and Budget (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.
K. Executive Order 13609 and International Trade Analysis
E.O. 13609 (``Promoting International Regulatory Cooperation'')
\13\ 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.
---------------------------------------------------------------------------
\13\ 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 will not cause unnecessary obstacles to foreign trade.
L. Cybersecurity and Executive Order 14028
E.O. 14028 (``Improving the Nation's Cybersecurity'') \14\ 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.
