Jersey Avenue SE, East Building, 2nd Floor, Washington, DC 20590-0001.
SUPPLEMENTARY INFORMATION:
I. Background and Need for Correction
The Pipeline and Hazardous Materials Safety Administration (PHMSA)
published final rule HM-260B \1\ to correct editorial errors and
improve the clarity of certain provisions in PHMSA's program and
procedural regulations and in the Hazardous Materials Regulations (HMR;
49 Code of Federal Regulations parts 171-180). The intended effect of
the rulemaking was to enhance accuracy and reduce misunderstandings of
the HMR. The changes in the final rule included numerous amendments to
the Sec. 172.101 Hazardous Materials Table (HMT). Unfortunately, the
amendments to the table entries for various hazardous materials
introduced new unintended errors that PHMSA is correcting in this
notice. The unintended errors are summarized below.
---------------------------------------------------------------------------
\1\ 87 FR 79752 (Dec. 27, 2022).
---------------------------------------------------------------------------
UN2258, 1,2-Propylenediamine: In HM-260B, PHMSA removed special
provision A6 from column (7) of the Sec. 172.101 HMT for several
hazardous materials including ``UN2258, 1,2-Propylenediamine.'' Special
provision A6 was removed because it had been inadvertently added back
to the Sec. 172.101 HMT when making unrelated changes to entries in
final rule HM-219C.\2\ UN2258, 1,2-Propylenediamine is a Class 8
corrosive liquid material that also has a secondary Class 3 flammable
hazard. Thus, in column (6) of the table, the codes ``8'' and ``3'' are
specified for the hazard labels required for a package containing this
material. However, in HM-260B, we inadvertently omitted reference to
the ``3'' from column (6). The absence of the ``3'' will create
uncertainty for shippers and carriers of ``UN2258, 1,2-
Propylenediamine'' as to whether a Class 3 label is required on a
package containing this material. To meet the original intent of HM-
260B to enhance accuracy and reduce misunderstandings of the HMR, PHMSA
is correcting this error in this notice. See Section III. Corrections.
---------------------------------------------------------------------------
\2\ 85 FR 75680 (Nov. 25, 2020).
---------------------------------------------------------------------------
Vessel stowage codes: In HM-260B, PHMSA also made several revisions
to correct inadvertent omissions of vessel stowage codes from column
(10B) to the Sec. 172.101 HMT for the entries ``UN1783,
Hexamethylenediamine solution, 8, III,'' ``UN1788, Hydrobromic acid,
with not more than 49 percent hydrobromic acid,'' and ``UN1740,
Hydrogendifluoride, solid, n.o.s., 8, III.'' Column (10B) assigns
specific codes for the stowage and handling requirements for specific
hazardous materials transported by vessel. In HM-219C, PHMSA had
inadvertently omitted stowage code ``52'' for the Packing Group (PG)
III entry for ``Hexamethylenediamine solution'' and stowage codes
``53'' and ``58'' for the PG III entry for ``Hydrogendifluoride, solid,
n.o.s,'' when making unrelated changes to these entries to specify
reference citations for authorized packaging exceptions.
Stowage code ``52'' means stow ``separated from'' acids. Stowage
codes ``53'' and ``58'' mean stow ``separated from'' alkaline compounds
and stow ``separated from'' cyanides, respectively. These stowage codes
are important to ensure proper segregation between acids and both
amines and cyanides. Amines react dangerously with acids and evolving
heat, and the heat of reaction has the potential to generate corrosive
vapors. Cyanides react with acids to generate toxic vapors. PHMSA
attempted to add the respective stowage codes back to column (10B)
under HM-260B but instead added the stowage codes to column (7), which
assigns special provisions applicable to certain Sec. 172.101 HMT
entries. More specifically, stowage code ``52'' was added to both
column (7) and column (10B) for ``Hexamethylenediamine solution, II''
and stowage codes ``53'' and ``58'' were added to column (7) and not
column (10B) for ``Hydrogendifluoride, solid, n.o.s., III.''
Readers may misinterpret unrelated special provisions as being
applicable and that the stowage codes that were inadvertently omitted
would not apply. For example, special provision ``53'' requires
packages to display a subsidiary risk label ``EXPLOSIVE'' along with
the subsidiary hazard indicated in the shipping description. If ``53''
were to remain in column (7) for the PG III entry of
``Hexamethylenediamine solution''--which is a corrosive material that
does not have an explosive hazard--persons would be mischaracterizing
the hazard for the material.
Additionally, in final rule HM-215O,\3\ PHMSA inadvertently omitted
stowage codes ``53'' and ``58'' for the entry ``UN1788, Hydrobromic
acid, with not more than 49 percent hydrobromic acid.'' PHMSA had made
numerous changes to the stowage codes assigned to hazardous materials
in the Sec. 172.101 HMT for consistency with the International
Maritime Dangerous Goods (IMDG) Code for regulation of hazardous
material transported by vessel including for the companion entry
``UN1788, Hydrobromic acid, with more than 49 percent hydrobromic
acid.'' The IMDG Code Dangerous Goods List has just one table entry for
``UN1788, Hydrobromic acid,'' but
[[Page 4757]]
PHMSA splits it into two hazardous materials descriptions because of
varying safety measures dependent on the mode of transport. For
instance, ``UN1788, Hydrobromic acid, with more than 49 percent
hydrobromic acid,'' is forbidden for transport by air. PHMSA attempted
to add the respective stowage codes to column (10B) of the Sec.
172.101 HMT to the ``not more than'' entry of UN1788 but inadvertently
omitted the ``not'' from the hazardous materials description
effectively making the changes apply to the ``more than'' entry of
UN1788. PHMSA also inadvertently omitted stowage code ``8'' in the
process. If these errors remain uncorrected, readers may misinterpret
the provisions that apply to the ``more than'' entry as now applying to
the ``not more than'' entry and that the missing stowage codes would
not apply when transporting this material. To meet the intent of HM-
260B to enhance accuracy and reduce misunderstandings of the HMR, PHMSA
is correcting these errors in this notice. See Section III.
Corrections.

II. Regulatory Analyses and Notices
A. Statutory/Legal Authority
Statutory authority for this correction notice is provided by the
Federal Hazardous Materials Transportation Law (49 U.S.C. 5101 et
seq.). The Secretary delegated the authority granted in this law to the
PHMSA Administrator at 49 CFR 1.97(b).
PHMSA finds it has good cause to make the corrections without
notice and comment pursuant to Section 553(b) of the Administrative
Procedure Act (APA, 5 U.S.C. 551, et seq.). Section 553(b)(B) of the
APA provides that, when an agency for good cause finds that notice and
public procedure are impracticable, unnecessary, or contrary to the
public interest, the agency may issue a rule without providing notice
and an opportunity for public comment. As explained above, the changes
to the text of the final rule document provided in this notice consist
of corrections to preamble discussion of Sec. 172.101 HMT and
corrections to the regulatory text in the amendatory instruction for
changes to Sec. 172.101 HMT. The publication of this correction notice
is needed to ensure the accuracy and reduce misunderstanding of
unintended changes or omissions to Sec. 172.101 HMT.
The January 26, 2023, effective date of the revisions contained in
this notice is authorized under both Section 553(d)(1) and (3) of the
APA. Section 553(d)(1) provides that a rule should take effect ``not
less than 30 days'' after publication in the Federal Register except
for ``a substantive rule which grants or recognizes an exemption or
relieves a restriction,'' while Section 553(d)(3) allows for earlier
effectiveness for good cause found by the agency and published within
the rule. 5 U.S.C. 553(d)(1), (3). ``The purpose of the thirty-day
waiting period is to give affected parties a reasonable time to adjust
their behavior before the final rule takes effect.'' Omnipoint Corp. v.
F.C.C., 78 F.3d 620, 630 (D.C. Cir. 1996). Since this final rule has
not yet taken effect, the impact on affected parties is minimal and
such parties will not be adversely impacted by the shortened period
before the correction becomes effective. The corrections in this notice
accurately represent the intended changes to the Sec. 172.101 HMT in
the final rule and, in accordance with 5 U.S.C. 553(d)(1), are
effective January 26, 2023. Moreover, PHMSA finds that good cause under
Section 553(d)(3) supports making the revisions effective January 26,
2023, because the corrections contained in this notice are entirely
consistent with the final rule--which itself was published on December
27, 2022--and helps promote accuracy and understanding of the Sec.
172.101 HMT requirements prior to the January 26, 2023, effective date.
B. Executive Order 12866 and DOT Regulatory Policies and Procedures
This notice has been evaluated in accordance with existing policies
and procedures and is considered not significant under Executive Order
12866 (``Regulatory Planning and Review'') and DOT Order 2100.6A
(``Rulemaking and Guidance Procedures''); therefore, this notice has
not been reviewed by the Office of Management and Budget (OMB) under
Executive Order 12866. PHMSA finds that the corrections in the notice
(in all respects consistent with the final rule) neither impose
incremental compliance costs nor adversely affect safety.
C. Regulatory Flexibility Act and Executive Order 13272
The Regulatory Flexibility Act (5 U.S.C. 601, et seq.) requires
agencies to review regulations to assess their impact on small entities
unless the agency head certifies that a rulemaking will not have a
significant economic impact on a substantial number of small entities
including small businesses, not-for-profit organizations that are
independently owned and operated and are not dominant in their fields,
and governmental jurisdictions with populations under 50,000. The
Regulatory Flexibility Act directs agencies to establish exceptions and
differing compliance standards for small businesses when possible to do
so and still meet the objectives of applicable regulatory statutes.
Executive Order 13272 (``Proper Consideration of Small Entities in
Agency Rulemaking'') \4\ requires agencies to establish procedures and
policies to promote compliance with the Regulatory Flexibility Act and
to ``thoroughly review draft rules to assess and take appropriate
account of the potential impact'' of the rules on small businesses,
governmental jurisdictions, and small organizations. DOT posts its
implementing guidance on a dedicated web page.\5\
---------------------------------------------------------------------------
\4\ 67 FR 53461 (Aug. 16, 2002).
\5\ 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 June 17, 2021).
---------------------------------------------------------------------------
The final rule was developed in accordance with Executive Order
13272 and with DOT's procedures and policies to promote compliance with
the Regulatory Flexibility Act and ensure that potential impacts of
draft rules on small entities are properly considered. There are no
costs to small entities associated with the final rule. The final rule
made non-substantive changes that do not impose new requirements, so
there are no direct or indirect adverse economic impacts for small
units of government, businesses, or other organizations. This notice
similarly does not impose new requirements but makes corrections to
errors in the final rule document in the amendments to the Sec.
172.101 HMT that if left uncorrected would be inaccurate and cause
misunderstanding by stakeholders as to what requirements apply.
Consequently, PHMSA certifies that neither the final rule nor this
notice has a significant economic impact on a substantial number of
small entities.
D. Paperwork Reduction Act
Under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501, et
seq.), no person is required to respond to any information collection
unless it has been approved by OMB and displays a valid OMB control
number. Section 1320.8(d) of 5 CFR requires that PHMSA provide
interested members of the public and affected agencies an opportunity
to comment on information and recordkeeping requests. The corrections
in this notice impose no new or revised information collection.
E. Unfunded Mandates Reform Act of 1995
The Unfunded Mandates Reform Act of 1995 (UMRA; 2 U.S.C. 1501, et
seq.) requires agencies to assess the effects of
[[Page 4758]]
federal regulatory actions on state, local, and tribal governments, and
the private sector. For any final rule that includes a federal mandate
that may result in the expenditure by state, local, and tribal
governments, or by the private sector 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. The final rule
did not impose unfunded mandates under the UMRA and this notice to
correct errors in the final rule document also does not impose unfunded
mandates. It does not result in costs of $100 million or more in 1996
dollars to either state, local, or tribal governments, or to the
private sector in any one year and is the least burdensome alternative
that achieves the objective of the rule.
F. National Environmental Policy Act
The National Environmental Policy Act of 1969 (NEPA), as amended
(42 U.S.C. 4321 et seq.), and implementing regulations by the Council
on Environmental Quality (40 CFR part 1500) requires federal agencies
to consider the consequences of federal actions and prepare a detailed
statement on actions that significantly affect the quality of the human
environment. DOT Order 5610.1C, ``Procedures for Considering
Environmental Impacts,'' establishes departmental procedures for
evaluating environmental impacts under NEPA and its implementing
regulations. The purpose of the final rule was to introduce non-
substantive changes that do not impose new requirements in order to
improve accuracy and understanding of the HMR. The corrections to the
final rule in this notice similarly do not impose new requirements.
Therefore, PHMSA has determined that implementing this final rule will
not significantly impact the quality of the human environment.
G. Executive Order 13132
The final rule was analyzed in accordance with the principles and
criteria contained in Executive Order 13132 (``Federalism'') \6\ and
its implementing Presidential Memorandum (``Preemption'').\7\ Executive
Order 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 corrections in this notice are consistent with, and
facilitate compliance with, the final rule, and do not have any
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 beyond what was
accounted for in the final rule. It does not contain any provision that
imposes any substantial direct compliance costs on state and local
governments, nor any new provision that preempts state law. Therefore,
the consultation and funding requirements of Executive Order 13132 do
not apply.

H. Environmental Justice
Executive Orders 12898 (``Federal Actions to Address Environmental
Justice in Minority Populations and Low-Income Populations''),\8\ 13985
(``Advancing Racial Equity and Support for Underserved Communities
Through the Federal Government''),\9\ 13990 (``Protecting Public Health
and the Environment and Restoring Science To Tackle the Climate
Crisis''),\10\ 14008 (``Tackling the Climate Crisis at Home and
Abroad'') \11\ and DOT Order 5610.2C (``Department of Transportation
Actions to Address Environmental Justice in Minority Populations and
Low-Income Populations'') require DOT agencies to achieve environmental
justice as part of their mission by identifying and addressing, as
appropriate, disproportionately high and adverse human health or
environmental effects, including interrelated social and economic
effects of their programs, policies, and activities on minority
populations, low-income populations, and other underserved and
disadvantaged communities.
---------------------------------------------------------------------------

\9\ 86 FR 7009 (Jan. 20, 2021).
\10\ 86 FR 7037 (Jan. 20, 2021).
\11\ 86 FR 7619 (Feb. 1, 2021).
---------------------------------------------------------------------------
PHMSA evaluated the final rule under the above Executive Orders and
DOT Order 5610.2C and did not expect the final rule to cause
disproportionately high and adverse human health and environmental
effects on minority, low-income, underserved, and other disadvantaged
populations and communities. The final rule was facially neutral and
national in scope; it was neither directed toward a particular
population, region, or community, nor was it expected to adversely
impact any particular population, region, or community. Since PHMSA did
not expect the final rule to adversely affect the safe transportation
of hazardous materials generally, PHMSA does not expect the corrections
to the final rule in this notice to involve disproportionately high
adverse risks for minority populations, low-income populations, or
other underserved and other disadvantaged communities.
I. Executive Order 13175
The final rule was analyzed in accordance with the principles and
criteria contained in Executive Order 13175 (``Consultation and
Coordination with Indian Tribal Governments'') \12\ and DOT Order
5301.1 (``Department of Transportation Policies, Programs, and
Procedures Affecting American Indians, Alaska Natives, and Tribes'').
Because none of the corrections have Tribal implications or impose
substantial direct compliance costs on Indian Tribal governments, the
funding and consultation requirements of Executive Order 13175 do not
apply.
---------------------------------------------------------------------------
\12\ 65 FR 67249 (Nov. 6, 2000).
---------------------------------------------------------------------------
Executive Order 13175 and DOT Order 5301.1 require DOT Operating
Administrations to assure meaningful and timely input from Indian
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 and distribution of
power between the Federal Government and Native American Tribes. PHMSA
assessed the impact of this final rule and determined that it did not
significantly or uniquely affect tribal communities or Native American
Tribal governments. The changes to the HMR as written in the final rule
are facially neutral and have broad, national scope. PHMSA therefore,
expected the final rule not to affect tribal communities significantly
or uniquely, much less impose substantial compliance costs on Native
American Tribal governments or mandate tribal action. Because PHMSA
expects the final rule will not adversely affect the safe
transportation of hazardous materials generally, PHMSA does not expect
it will entail disproportionately high adverse risks for tribal
communities. For these reasons, PHMSA concluded the funding and
consultation requirements of Executive Order 13175 and DOT Order 5301.1
do not apply. Similarly, PHMSA does not expect the corrections to the
final rule in this notice to affect tribal communities significantly or
uniquely, much less impose substantial
[[Page 4759]]
compliance costs on Native American Tribal governments or mandate
tribal action.
J. Executive Order 13609 and International Trade Analysis
Under Executive Order 13609 (``Promoting International Regulatory
Cooperation''),\13\ agencies must 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. The
corrections to the final rule in this notice do not impact
international trade.
---------------------------------------------------------------------------
\13\ 77 FR 26413 (May 4, 2012).
---------------------------------------------------------------------------
K. National Technology Transfer and Advancement Act
The National Technology Transfer and Advancement Act of 1995 (15
U.S.C. 272 note) directs federal agencies to use voluntary consensus
standards in their regulatory activities unless doing so would be
inconsistent with applicable law or otherwise impractical. Voluntary
consensus standards are technical standards (e.g., specification of
materials, test methods, or performance requirements) that are
developed or adopted by voluntary consensus standard bodies. The
corrections to the final rule do not invoke any voluntary consensus
standards, so the National Technology Transfer and Advancement Act of
1995 is not applicable in this case.
Corrections
PHMSA makes corrections to both the preamble and regulatory text of
the final rule document. PHMSA is correcting the preamble discussion of
changes to column (7) of the Sec. 172.101 HMT by removing discussion
of changes to the entries ``UN1783, Hexamethylenediamine solution, 8,
III,'' and ``UN1740, Hydrogendifluoride, solid, n.o.s., 8, III,'' which
misconstrue the intended vessel storage codes changes as special
provision changes and correctly adds to the discussion of column (10B)
changes as discussion of vessel stowage code changes for these
materials. Additionally, PHMSA is correctly revising the Sec. 172.101
HMT entries for the hazardous materials discussed above in Section I.
In FR Doc. 2022-26960, appearing on page 79752 in the Federal
Register of Tuesday, December 27, 2022, the following corrections are
made:
Corrections to Preamble
1. On page 79755, in the 3rd column, beginning at the bullet
paragraphs starting with ``For ``UN1740'''' and ``For ``UN1783'''', the
following are correctly removed:
<bullet> For ``UN1740, Hydrogendifluoride, solid, n.o.s., 8, PG
III,'' PHMSA is correcting an error where special provisions 53 and 58
are missing from column 7.
<bullet> For ``UN1783, Hexamethylenediamine solution, 8, PG III,
PHMSA is correcting an error where special provision 52 is missing from
column 7.
2. On page 79756, in the 2nd column at the end of the first
paragraph and before the heading ``Section 172.102,'' the following is
correctly added:
<bullet> In column (10B) for ``UN1740, Hydrogendifluoride, solid,
n.o.s., 8, PG III,'' stowage codes ``53'' and ``58'' are missing. PHMSA
inadvertently omitted these stowage codes when making changes to this
entry in HM-219C to allow packaging exceptions. Stowage code ``53''
provision means stow ``separated from'' alkaline compounds and stowage
code ``58'' provision means stow ``separated from'' cyanides. PHMSA is
amending the HMT to add the stowage codes back to column (10B). This
amendment will ensure that this material is properly stowed for safe
vessel transport.
<bullet> In column (10B) for ``UN1783, Hexamethylenediamine
solution, 8, PG III,'' stowage code ``52'' is missing. PHMSA
inadvertently omitted this stowage code when making changes to this
entry in HM-219C to allow packaging exceptions. Stowage code ``52''
provision means stow ``separated from'' acids. PHMSA is amending the
HMT to add the stowage code back to column (10B). This amendment will
ensure that this material is properly stowed for safe transport.
