I. Background

    The Pipeline and Hazardous Materials Safety Administration (PHMSA),
in this final rule, is amending the Hazardous Materials Regulations
(HMR; 49 Code of Federal Regulations (CFR) parts 171-180) to correct
typographical errors; fix incorrect regulatory references and
citations; remove obsolete references to regulatory provisions, dates,
as well as outdated concepts such as other regulated materials-domestic
(ORM-D); address misstatements of certain regulatory requirements; and
supply information or language that had been inadvertently omitted.
Further, within the scope of this rulemaking, PHMSA is revising certain
procedural regulations at 49 CFR parts 107 and 110 to make them easier
to understand. PHMSA expects the regulatory amendments adopted in this
final rule will ensure stakeholders focus their resources on compliance
with pertinent safety requirements of the HMR rather than trying to
resolve erroneous, ambiguous, or obsolete language within PHMSA's
regulations.
    The amendments contained in this final rule are non-substantive
changes that do not impose new requirements that necessitate public
comment. The final rule's amendments are consistent with PHMSA's
historical practice of regularly reviewing the HMR and PHMSA's program
and procedural regulations for opportunities to eliminate regulatory
confusion, fix typographical errors and omissions, and remove obsolete
material and references.

II. Removing Outdated References to Other Regulated Materials-Domestic
(ORM-D)

    In 2011, PHMSA published final rule HM-215K \1\ in which PHMSA
amended the HMR to maintain alignment with updates to certain
international standards and regulations. Among these amendments, PHMSA
adopted changes to align existing limited quantity provisions with the
global system of transport of limited quantity material under
international standards and regulations including the International
Maritime Dangerous Goods (IMDG) Code, the International Civil Aviation
Organization's (ICAO) Technical Instructions for the Safe Transport of
Dangerous Goods by Air, and the United Nations (UN) Recommendations on
the Transport of Dangerous Goods--Model Regulations. These changes
included the phase-out of existing provisions in the HMR for limited
quantities reclassed as ORM-D (e.g., limited quantity material defined
as consumer commodities). This shift allowed for the use of a single
global system for the transportation of limited quantities of hazardous
materials and would transition shipments within the United States away
from the domestic provisions for ORM-D reclassification and marking for
certain limited quantity hazardous materials. Specifically, PHMSA
adopted sunset dates for use of the domestic ORM-D classification and
associated package marking ``Consumer commodity, ORM-D.'' Hazardous
materials transported by air had an implementation date of January 1,
2013, and hazardous materials transported by all other modes had an
implementation date of January 1, 2014.
---------------------------------------------------------------------------

    \1\ 76 FR 3308 (Jan. 19, 2011).
---------------------------------------------------------------------------

    In response to appeals to final rule HM-215K,\2\ PHMSA extended the
authorized use of the ORM-D classification and packages marked
``Consumer commodity, ORM-D'' for domestic highway, rail, and vessel
transportation until December 31, 2020, to allow sufficient time for
domestic shippers and carriers to adjust to this revised global system
of transporting limited quantity materials. Since this phase-out period
has passed--and use of the ORM-D classification is no longer
authorized--PHMSA is removing any reference to ORM-D from the HMR in
the following locations:

III. Updating Titles to Subpart B of Part 177

    In part 177, subpart B--Loading and Unloading, some of the
regulatory provision titles in the subpart reference the hazard class
with a descriptive term while other titles reference only the hazard
class number (e.g., Class 8 (corrosive) materials vs Class 1
materials). For consistency and uniformity within subpart B, PHMSA
amends the titles to include a descriptive term associated with the
hazard class in the following sections:

 Sec.  177.835--Class 1 (explosive) materials
 Sec.  177.837--Class 3 (flammable liquid and combustible
liquid) materials
 Sec.  177.841--Division 6.1 (poisonous) materials and Division
2.3 (poisonous gas) materials

IV. Section-by-Section Review of Changes

    In addition to the specific changes noted in ``Section II. Removing
Outdated References to Other Regulated Materials-Domestic (ORM-D),''
the following is a section-by-section summary of the editorial
corrections and clarifications made in this final rule. PHMSA is also
making minor technical corrections throughout the HMR to align cross-
references with current regulatory requirements and provisions.

A. Part 107

Section 107.109
    This paragraph provides the requirements to apply for the renewal
of a special permit. In paragraph (a)(4) of Sec.  107.109, a person
must include a certification that the original application, as updated
by any application for renewal, remains accurate. PHMSA provides
examples, in parentheses, of information that must be certified by a
person for the renewal of a special permit application (e.g., all
section references, shipping description, etc.). To clarify additional
information a person must certify, PHMSA revises paragraph (a)(4) by
including ``email address'' among the information that must be accurate
before submitting a renewal application for a special permit.
Certifying an accurate email address will allow for a timely response
from PHMSA and avoid unnecessary delays in the special permit renewal
process.
Section 107.502
    This section provides the general registration requirements for
cargo tanks and cargo tank motor vehicles. In Sec.  107.502(d), PHMSA
is revising the Federal Motor Carrier Safety Administration (FMCSA)
Hazardous Materials Division designation ``MC-ECH'' to read ``MC-SEH.''
PHMSA is also revising the FMCSA mailing address for registration
statements to remove redundant reference to the division designation
within the address.

B. Part 110

Section 110.7
    This section provides the Office of Management and Budget (OMB)
control number assigned to each collection of information. In final
rule HM-209A,\3\ PHMSA revised the HMR to align with OMB's Uniform
Administrative Requirements, Cost Principles, and Audit Requirements
for Federal Awards (2 CFR part 200), as well as new requirements
outlined in the Fixing America's Surface Transportation Act of 2015
(Pub. L. 114-94). In HM-209A, PHMSA removed and reserved Sec. Sec.
110.70, 110.80, and 110.90 to eliminate duplicative language found in 2
CFR part 200. However, PHMSA did not make an accompanying revision to
Sec.  110.7, which still contains the now reserved sections. Therefore,
PHMSA is removing the reference to the reserved sections currently
found in Sec.  110.7.
---------------------------------------------------------------------------

    \3\ 84 FR 3993 (Feb. 14, 2019).
---------------------------------------------------------------------------

C. Part 171

Section 171.6
    This section provides the OMB control numbers assigned to
collections of information within the HMR. In final rule HM-251,\4\
PHMSA requested a new information collection under OMB Control No.
2137-0628 titled ``Flammable Hazardous Materials by Rail
Transportation.'' PHMSA inadvertently left out OMB control number 2137-
0628 from the Sec.  171.6(b)(2) table, and therefore, PHMSA is adding
the missing control number, title, and reference sections, as
appropriate, for full transparency of authorized HMR information
collections.
---------------------------------------------------------------------------

    \4\ 80 FR 26643 (May 8, 2015).
---------------------------------------------------------------------------

Section 171.7
    This section lists material incorporated by reference into the HMR.
In final rule HM-215N,\5\ PHMSA amended the HMR to maintain consistency
with international regulations and standards by harmonizing with
changes made to the IMDG Code, the ICAO Technical Instructions, and the
UN Model Regulations. However, PHMSA made a typographical error that
incorrectly changed the publication date for the referenced edition of
the International Organization for Standardization standard ``ISO
4706:2008(E).'' The publication date was inadvertently changed from
``2008-04-15'' as presented in the notice of proposed rulemaking (NPRM)
for HM-215N \6\ to ``2008-07-014,'' which is incorrect. PHMSA is
correcting this error to accurately reflect the ISO publication date of
the version incorporated by reference to read: ``ISO 4706:2008(E), Gas
cylinders--Refillable welded steel cylinders--Test pressure 60 bar and
below, First Edition, 2008-04-15, Corrected Version, 2008-07-01'' into
Sec.  178.71.
---------------------------------------------------------------------------

    \5\ 82 FR 15796 (Mar. 30, 2017).
    \6\ 81 FR 61741 (Sep. 7, 2016).
---------------------------------------------------------------------------

    In final rule HM-224B \7\ and in consultation with the Federal
Aviation Administration (FAA), PHMSA amended the HMR to authorize the
use of Air Transport Association Specification 300 for Type I (ATA 300)
shipping containers. Because of extensive testing and research, PHMSA
eliminated special provision ``A52'' and relocated ``Oxygen,
compressed'' packaging requirements from one or more of Sec. Sec.
173.168(d), 173.302(f)(3), and 173.304(f)(3). However, PHMSA did not
list these sections in Sec.  171.7(b) in association with the ATA 300
standard incorporated by reference. Therefore, PHMSA is revising Sec.
171.7(b)(1) ``ATA Specification No. 300 Packaging of Airline Supplies,
Revision 19, July 31, 1996'' to include a reference to Sec. Sec.
173.168(d), 173.302(f)(3), and 173.304(f)(3). In addition, PHMSA
includes a cross-reference to Sec.  171.7 within each of those same
sections.
---------------------------------------------------------------------------

    \7\ 72 FR 4442 (Jan. 31, 2007).
---------------------------------------------------------------------------

    Finally, PHMSA was notified by the Compressed Gas Association (CGA)
that their address in Sec.  171.7(n) was outdated. As such, PHMSA is
amending the address from ``1235 Jefferson Davis Highway, Arlington, VA
22202'' to ``8484 Westpark Drive, Suite 220, McLean, VA 22102'' per
CGA's request.

Section 171.8
    This section provides definitions and abbreviations used within the
HMR. In final rule HM-215K,\8\ PHMSA revised the definition of
``Oxidizing gas,'' but the outdated definition inadvertently remains in
this section as a duplicate definition that is a source of confusion.
Therefore, PHMSA is removing the outdated first definition of
``Oxidizing gas'' listed in the section to avoid any confusion on the
applicable definition and thereby, enhancing safety for the regulated
community. The version being removed reads: ``Oxidizing gas means a gas
which may, generally by providing oxygen, cause or contribute to the
combustion of other material more than air does.''
---------------------------------------------------------------------------

    \8\ 76 FR 3308 (Jan. 19, 2011).
---------------------------------------------------------------------------

Section 171.12
    This section provides requirements specific to North American
shipments of hazardous materials. Paragraph (b) of the section
addresses shipments to or from Mexico. Moreover, paragraph (b) sets out
specific requirements for shipments of material poisonous by inhalation
(PIH). In Sec.  171.12(b)(4), there is a reference to nonexistent
paragraph (e)(5). Current paragraph (b)(4) reads that packages of PIH
material are to be labeled and placarded as POISON GAS or POISON
INHALATION HAZARD in accordance with the HMR, except as provided in
(e)(5); and current paragraph (b)(5) indicates a label or placard
conforming to the UN Model Regulations may be substituted for a POISON
GAS or POISON INHALATION HAZARD label or placard. In final rule HM-
215F,\9\ PHMSA revised and consolidated provisions applying to North
American shipments, which, in part, redesignated previous paragraphs
(e)(1) through (e)(5) as paragraphs (b)(1) through (b)(5). However, in
HM-215F, PHMSA did not make a conforming amendment to revise the
reference to previous paragraph (e)(5) to redesignated (b)(5). Thus,
PHMSA will change the paragraph reference from ``(e)(5)'' to ``(b)(5)''
to appropriately reference the alternative way to label or placard a
PIH package.
---------------------------------------------------------------------------

    \9\ 72 FR 25161 (May 3, 2007).
---------------------------------------------------------------------------

Section 171.15
    This section provides the requirements for the immediate notice of
certain hazardous materials incidents. In Sec.  171.15(a), PHMSA is
revising this paragraph by removing the URL link to http://www.nrc.uscg.mil as it is no longer a valid resource for reporting
hazardous material incidents. As revised, Sec.  171.15 would require
persons to instead contact the National Response Center hotline at 1-
800-424-8802.

D. Part 172

Section 172.101
    This section contains the Hazardous Materials Table (HMT) and
explanatory text for each of the columns in the table. In this final
rule, PHMSA is amending the HMT explanatory text as described below:
     Section 172.101(f) addresses column (5) of the HMT for
assignment of the packing group and explains that certain Classes and
Divisions of hazardous materials are not assigned packing groups. This
includes Division 6.2 materials other than Division 6.2 regulated
medical wastes. However, in final rule HM-215P,\10\ PHMSA removed the
assignment of PG II in column (5) for the hazardous materials
description ``UN3291, Regulated medical waste, n.o.s. or Clinical
medical waste, unspecified, n.o.s. or (BIO) Medical waste, n.o.s. or
Biomedical waste, n.o.s., or Medical Waste n.o.s.'' creating an
inconsistency with the text in Sec.  172.101(f). Accordingly, PHMSA is
revising the second sentence of Sec.  172.101(f) by deleting the
parenthetical text ``(other than regulated medical wastes)'' to remove
any possible misunderstanding that Division 6.2 regulated medical
wastes are not assigned a packing group and thus removing a source of
confusion whether to indicate the packaging group on a shipping paper
for regulated medical waste.
---------------------------------------------------------------------------

    \10\ 87 FR 44944 (Jul. 26, 2022).
---------------------------------------------------------------------------

     In final rule HM-218C,\11\ PHMSA amended the HMR by
adopting miscellaneous changes based on petitions for rulemaking and
PHMSA initiatives. In HM-218C, PHMSA amended Sec.  172.101(i)(3) by
adding a statement to clarify that some bulk packaging authorizations
are found in column (8B) and the special provisions in column (7) of
the HMT. However, PHMSA inadvertently removed subparagraphs (i-iii)
from Sec.  172.101(i)(3); therefore, PHMSA will add the subparagraphs
back to this section.
---------------------------------------------------------------------------

    \11\ 70 FR 34066 (Jun. 13, 2005).
---------------------------------------------------------------------------

    Additionally, PHMSA is making corrections to information in the HMT
as follows:
Column 1--Symbol Changes
     PHMSA is correcting an inadvertent deletion of the ``G''
symbol for the following entries: ``UN2920, Corrosive liquid, self-
heating, n.o.s., 8, PG I,'' ``UN2921, Corrosive solids, flammable,
n.o.s., 8, PG I,'' and ``UN2925, Flammable solids, corrosive, organic,
n.o.s., 4.1, PG II'' by adding the ``G'' symbol for these entries. The
assignment of a ``G'' identifies a proper shipping name (PSN) for which
one or more technical names of the hazardous material must be entered
in parentheses, in association with the basic description (i.e., with
the UN identification number, the PSN, the hazard class, and the
packing group). These HMT entries are n.o.s. PSNs and as defined in
Sec.  171.8, ``N.O.S.'' means not otherwise specified. Because they do
not specify a technical name for the hazardous material, n.o.s. PSNs
are typically assigned ``G'' in column (1).
Column 2--PSN Changes
     PHMSA is correcting an inadvertent typo where the language
in italics for ``UN1263, Paint including paint, lacquer, enamel, stain,
shellac solutions, varnish, polish, liquid filler and liquid lacquer
base'' is missing a set of parentheses to indicate the language in
italics is not a part of the PSN. PHMSA is correcting this error by
including a parenthesis before the word ``including'' and after the
word ``base.''
     In final rule HM-219C,\12\ PHMSA amended the HMR in
response to petitions for rulemaking. HM-219C revised the
transportation requirements for limited quantity shipments of hydrogen
peroxide including revising the HMT entries to harmonize the limited
quantity exceptions with the ICAO Technical Instructions and the UN
Model Regulations. For ``UN2014, Hydrogen, peroxide, aqueous solutions
with more than 40 percent, but not more than 60 percent hydrogen
peroxide (stabilized as necessary), 5.1, PG II'' and ``UN2014, Hydrogen
peroxide, aqueous solutions with not less than 20 percent, but not more
than 40 percent hydrogen peroxide (stabilized as necessary), 5.1, PG
II,'' the HMT entries do not display the correct PSN. The language
``with more than 40 percent, but not more than 60 percent hydrogen
peroxide (stabilized as necessary)'' and ``with not less than 20
percent, but not more than 40 percent hydrogen peroxide (stabilized as
necessary),'' respectively, is displayed in Roman type font making it
appear that the text is part of the PSN. This is incorrect. The PSN is
``Hydrogen peroxide, aqueous solutions'' and the remainder of the
language should be italicized. As instructed in Sec.  172.101(c)(1),
words in italics are not part of the PSN, but may be used in addition
to the PSN. Therefore, PHMSA

is correcting this error to italicize the additional text.
---------------------------------------------------------------------------

    \12\ 85 FR 75680 (Nov. 25, 2020).
---------------------------------------------------------------------------

     For ``UN3021, Pesticides, liquid, flammable, toxic, flash
point less than 23 degrees C,'' the PSN as well as the explanatory text
regarding the flash point of the material is displayed in Roman type
font. In final rule HM-215M,\13\ PHMSA inadvertently revised the italic
font of the explanatory text for ``UN3021'' when the stowage code
assigned in the HMT for this entry was updated. By not having the
explanatory text in italics, the whole description reads as the PSN.
Therefore, PHMSA is amending the ``UN3021 entry to the following:
``UN3021, Pesticides, liquid, flammable, toxic, flash point less than
23 degrees C.''
---------------------------------------------------------------------------

    \13\ 80 FR 1076 (Jan. 8, 2015).
---------------------------------------------------------------------------

     For ``UN3321, Radioactive material, low specific activity
(LSA-III) non fissile or fissile-excepted,'' the explanatory text
regarding non fissile or fissile-excepted is displayed in Roman type
font, making the text part of the PSN, which is not the intent. In HM-
215O,\14\ PHMSA inadvertently revised the italic font for ``non fissile
or fissile-excepted'' when the table entry for ``UN3321'' was updated
to reflect the addition of special provision 325. Therefore, PHMSA is
amending the ``UN3321'' entry to the following: ``UN3321, Radioactive
material, low specific activity (LSA-III) non fissile or fissile-
excepted.''
---------------------------------------------------------------------------

    \14\ 85 FR 27810 (May 11, 2020).
---------------------------------------------------------------------------

     PHMSA is correcting a typographical error where the
language in the HMT shows the term ``wheel chair'' as two separate
words, which is incorrect. To clarify and to eliminate confusion, the
term should be one word and spelled as ``wheelchair'' instead.
Column 6--Label Code Changes
     In final rule HM-215P, the proper shipping name for
``UN3363, Dangerous Goods in Machinery or Dangerous Goods in Apparatus,
9,'' was revised to the following: ``UN3363, Dangerous goods in
articles or Dangerous goods in machinery or Dangerous goods in
apparatus, 9.'' This PSN revision is reflected in the current UN Model
Regulations. In making this revision to the PSN, PHMSA mistakenly
deleted the label code in column (6) for this table entry. Therefore,
PHMSA is correcting this error by adding label code ``9'' back to
column (6) to indicate a Class 9 label is required for this material.
Column 7--Special Provision Changes
     In final rule HM-233F,\15\ PHMSA added special provision
383 in association with adopting DOT special permit (DOT-SP) 11356 into
the HMR, which authorized a material meeting the conditions for high
viscosity flammable liquids specified in Sec.  173.121(b)(1)(i),
(b)(1)(ii), and (b)(1)(iv), to be re-classed to PG III for
transportation by motor vehicle. However, PHMSA inadvertently did not
add the new special provision to the following HMT entries: ``UN1139,
Coating solution (includes surface treatments or coatings used for
industrial or other purposes such as vehicle undercoating, drum or
barrel lining), 3, PG II'' and ``UN1263, 3, PG II'' even though these
materials were covered in DOT-SP 11356. PHMSA is correcting this
omission by adding special provision 383 to HMT entries ``UN1139'' and
``UN1263'', respectively.
---------------------------------------------------------------------------

    \15\ 81 FR 3636 (Jan. 21, 2016).
---------------------------------------------------------------------------

     In final rule HM-215P, PHMSA amended the regulations to
allow ``UN2216, Fish meal, stabilized or Fish scrap, stabilized, 9,
PGIII,'' to be transported by passenger and cargo aircraft subject to
specific quantity limitations for the material. When PHMSA proposed the
changes to this table entry, we did not propose removal of special
provision ``B136'' from column (7) nor did we propose to remove the
word ``None'' from column (6), yet we mistakenly deleted special
provision ``B136'' and the word ``None.'' Therefore, PHMSA is
correcting this error by adding special provision ``B136'' back to
column (7) and the word ``None'' back to column (6).
     For ``UN3084, Corrosive solids, oxidizing, n.o.s., PG
II,'' there is a typographical error where special provision 154 is
listed in column 7, but there is no such special provision in Sec.
172.102. Therefore, PHMSA is removing ``154'' from column 7.
     In final rule HM-259,\16\ PHMSA removed special provision
A6, which provided methods of packaging liquid hazardous material for
air transport, from certain HMT entries. Specifically, PHMSA removed
the assignment of A6 from liquid hazardous material. However, in HM-
219C, special provision A6 was inadvertently reassigned to some of the
entries from which they were originally removed. Therefore, PHMSA is
correcting this by again removing assignment of special provision A6
from the following:

are missing from column 7.
     For ``UN1783, Hexamethylenediamine solution, 8, PG III,
PHMSA is correcting an error where special provision 52 is missing from
column 7.
Column 8--Packaging Authorization Changes
     In column (8B) for ``UN2734, Amine, liquid, corrosive,
flammable, n.o.s. or Polyamines, liquid, corrosive, flammable, n.o.s.,
8, PG II,'' the packaging instruction was inadvertently changed from
``202'' to ``201.'' To correct this error, PHMSA will revert

the packaging instruction in column 8(B) back to ``202.'' The
packagings authorized under Sec.  173.201 are for liquid hazardous
materials in PG I. Section 173.202 provides authorized packagings for
liquid hazardous materials in PG II which is the correct packaging
section reference for this PG II material.
Column 10--Vessel Stowage Changes
     In column (10B) for ``UN1510, Tetranitromethane, 6.1, PG
I,'' there is a typographical error for one of the vessel stowage codes
assigned to this material. The stowage codes as currently listed for
``UN1510'' are ``40 and 6.'' The stowage code 6 is incorrect as it is
missing a ``6.'' PHMSA is amending column (10B) to reflect the correct
stowage code of ``66.'' Stowage code 6 instructs that a material is an
emergency temperature material, which is not relevant in the case of
stowage of tetranitromethane. Stowage code 66 instructs a person to
stow this material separated from flammable solids, which is consistent
with IMDG Code segregation code ``SG16'' assigned to ``UN1510'' to
``stow separated from Division 4.1'' (flammable solids). This amendment
will ensure that this material is properly stowed for safe transport.
     In column (10B) for ``UN2627, Nitrites, inorganic, n.o.s.,
5.1, PG II,'' there is a typographical error for one of the vessel
stowage codes assigned to this material. The stowage codes as listed
for ``UN2627'' are ``46, 56, 58, and 13.'' Stowage code 13 is incorrect
as it is missing a ``3.'' PHMSA is amending column (10B) to reflect the
correct stowage code of ``133.'' Stowage code 13 instructs to keep as
reasonably dry as possible, which is not relevant in the case of
stowage of inorganic nitrite. Stowage code 133 instructs to stow
``separate from sulfur,'' and is thus the appropriate stowage
instruction, and is consistent with Sec.  176.400(d) as well as IMDG
Code segregation code ``SG62'' assigned to ``UN2627'' to stow
``separated from'' sulfur. This amendment will ensure that this
material is properly stowed for safe transport.
     In column (10B), for ``UN1788, Hydrobromic acid, with not
more than 49 percent hydrobromic acid, 8, PG II'' and for ``UN1788,
Hydrobromic acid, with not more than 49 percent hydrobromic acid, 8, PG
III,'' stowage codes ``53'' and ``58'' are missing. Stowage code ``53''
provision means stow ``separated from'' alkaline compounds and stowage
code ``58'' provision means stow ``separated from'' cyanides. In final
rule HM-215O, PHMSA amended the HMR to maintain alignment with
international regulations and standards by incorporating various
amendments, including changes to vessel stowage requirements.
Consistent with changes made to Amendment 39-18 of the IMDG Code, PHMSA
made numerous changes to special stowage and segregation provisions,
specifically ``Other'' provisions as indicated in column (10B). Because
of these changes, ``UN1788'' for both PG II and PG III should have
stowage codes ``53'' and ``58'' listed in column (10B) therefore, PHMSA
is amending the HMT to reflect this inadvertent omission.
Section 172.102
    This section provides a list of special provisions as referred to
in Column (7) of the HMT. Regarding ``UN1408, Ferrosilicon with 30
percent or more, but less than 90 percent silicon, 4.3, PG III,'' it is
assigned IP code \17\ ``IP7'' in the HMT, yet the material (i.e., the
UN identification number) is not listed among the materials subject to
IP7. IP codes are special provisions on the use of intermediate bulk
containers (IBCs) for transport of certain hazardous materials. In
final rule HM-215G,\18\ the Research and Special Programs
Administration (RSPA)--now PHMSA--amended the HMR to align with
international standards, which included changes to special provisions.
The omission from special provision IP7 was inadvertent as ``UN1408''
is listed among materials subject to the same IBC special provision as
part of the IMDG Code. For clarity of understanding that IP7 applies to
ferrosilicon material, PHMSA is adding ``UN1408'' to the list of UN
identification numbers in IP7.

Section 172.202
    This section provides the requirements to describe hazardous
materials on shipping papers. In Sec.  172.202(a)(4), there is a
requirement to include the packing group (PG) \19\ with the required
shipping description of a hazardous material on a shipping paper.
However, certain types of hazardous materials are not assigned a ``PG''
because they do not exhibit a degree of danger that needs to be
communicated. For instance, batteries of all types, including lithium,
lithium ion, and sodium batteries, are not assigned a ``PG'' in the
HMT. In final rule HM-215M, PHMSA amended the HMR to maintain alignment
with international standards, which included removing the generalized
``PG II'' assignment for lithium ion batteries, lithium metal
batteries, and sodium batteries. However, the language in Sec.
172.202(a)(4) states that ``batteries other than those containing
lithium, lithium ions, or sodium'' are excepted from including a ``PG''
is a source of confusion because lithium, lithium ion, or sodium
batteries are no longer assigned a ``PG'' in the HMT. Therefore, PHMSA
is amending Sec.  172.202(a)(4) by removing reference to lithium,
lithium ion, and sodium batteries from this paragraph.
---------------------------------------------------------------------------

    \19\ Packing group means a grouping according to the degree of
danger presented by hazardous materials. Packing Group I indicates
great danger; Packing Group II, medium danger; Packing Group III,
minor danger.

Section 172.203
    This section provides additional description requirements for
shipping papers. Section 172.203(e)(1) and (e)(2) provide instruction
for the description of residue hazardous material on a shipping paper.
The language to include ``residue: last contained'' reads different in
the paragraphs, specifically, ``RESIDUE: Last Contained***'' in (e)(1)
and ``RESIDUE: LAST CONTAINED***'' in (e)(2). For consistency, PHMSA is
revising the language in (e)(2) to the following: ``RESIDUE: Last
Contained.'' Additionally, consistent with Sec.  172.101(l)(1)(ii),
stocks of preprinted shipping papers may be continued in use, with the
text previously required in (e)(2), until depleted or for a one-year
period, after the effective date of this rule, whichever is less.
Section 172.204
    This section provides the requirements for shipper's certification.
In final rule HM-216B,\20\ PHMSA amended the HMR to adopt provisions
contained in certain widely used or longstanding rail special permits,
which included revisions to the shipper certification for
transportation by rail. PHMSA had received a comment from Union Pacific
Railroad to revise the language in Sec.  172.204(a)(3)(ii) to the
following: ``Electronic certification. When transmitted electronically,
by entering the name of the principal person, partner, officer, or
employee of the offeror or his agent in a specific EDI.'' \21\ PHMSA
agreed with revising the language; and offered a revised version ``to
emphasize that by completing a signature field on an EDI document, the
shipper is certifying that the document complies with . . .

Sec.  172.204(a).'' However, stakeholders have reported that the
current language adopted in the HM-216B \22\ notice of proposed
rulemaking (``must be substituted for the asterisks'') is considered a
source of confusion because there are neither asterisks in the
certification statement in Sec.  172.204(a) nor in typical EDI
documents. To clarify this section for simplicity of understanding and
consistent with final rule HM-216B, PHMSA will amend Sec.
172.204(a)(3)(ii) to read as follows: ``Electronic Certification. When
transmitted electronically, by completing the field designated for the
shipper's signature with the name of the principal person, partner,
officer, or employee of the offeror or their agent, the shipper is also
certifying its compliance with the certification specified in Sec.
172.204(a).'' This revision is consistent with Sec.  172.204(d)(3)
certification signature requirements for transportation by rail that
requires ``the name of the principal person, partner, officer, or
employee of the offeror or his agent in a computer field defined for
that purpose.''

Section 172.315
    This section provides the requirements for limited quantities of
hazardous material. The dates for transitional exceptions in Sec.
172.315(d) allowing limited quantity marking requirements for
alternatively marked packages and ORM-D marked packages have passed.
Therefore, PHMSA is deleting and reserving paragraph (d) as the
transition periods no longer apply.
Section 172.332
    This section provides the requirements for identification number
markings. In Sec.  172.332(d), the placard dimensions illustrated in
this paragraph are incorrect. In final rule HM-218F,\23\ PHMSA amended
the HMR to make miscellaneous amendments to update and clarify certain
regulatory requirements. To align with international standards, PHMSA
authorized the use of placards measuring 250 mm (9.84 inches) on each
side. However, for the example used in Sec.  172.332(d) to illustrate
the display of an identification number on a placard, the placard
dimensions are not consistent with the current minimum size
requirements for a placard found in Sec.  172.519(c). Therefore, to
avoid confusion PHMSA is amending Sec.  172.332(d) by replacing the
illustration with one that does not have measurements.

Section 172.400
    This section provides general requirements for labeling of
packages. In the table to paragraph (b), there is a typo where the word
``Oxidizer'' is misspelled as ``Oxider.'' PHMSA is correcting this
misspelling by replacing it with the correct term ``Oxidizer.''
Section 172.519
    This section provides the requirements for general specifications
for placards. Section 172.519(c)(1)(i) currently states, ``A placard in
conformance with the requirements of this paragraph in effect on
December 31, 2014, may continue to be used until December 31, 2016.''
The transitional period for this exception to use a placard that
conforms to Sec.  172.519(c)(1) requirements effective at the end of
2014 has passed. Therefore, PHMSA is amending Sec.  172.519(c)(1) by
deleting the transitional exception reference and merging what is
currently in paragraphs (c)(1) introductory text and (c)(1)(ii)
together.

E. Part 173

Section 173.4a
    This section provides the requirements for excepted quantities of
hazardous material. The Sec.  173.4a(g)(2)(i) transitional exception
from the excepted quantities marking specifications states: ``A marking
in conformance with the requirements of this paragraph in effect on
December 31, 2014, may continue to be used until December 31, 2016.''
This transitional period for exception from certain marking
requirements has passed. Therefore, PHMSA is amending Sec.
173.4a(g)(2) by deleting the paragraph (g)(2)(i) transitional exception
and merging what is currently in paragraphs (g)(2) introductory text
and (g)(2)(ii) together.
Section 173.11
    This section provides exceptions for the shipment of light bulbs
containing hazardous materials. In Sec.  173.11(b), there is a
punctuation error at the end of the paragraph where a semicolon is used
instead of a period to separate the standalone provisions of paragraphs
(b) and (c) in this section. PHMSA is revising paragraph (b) by
replacing the semicolon with a period at the end of the paragraph to
clearly communicate that paragraph (b) and (c) are standalone
provisions.
Section 173.25
    This section provides the requirements for authorized packagings
and overpacks. Section 173.25(a)(4)(i) states: ``A marking in
conformance with the requirements of this paragraph in effect on
December 31, 2014, may continue to be used until December 31, 2016.''
The transitional exception period to mark an overpack has passed.
Therefore, PHMSA is amending Sec.  173.25(a)(4) by deleting this
transitional exception reference and merging what is currently in
paragraphs (a)(4) introductory text and (a)(4)(ii) together.
Section 173.27
    This section provides the general requirements for transportation
by aircraft. In HM-215P, PHMSA made numerous amendments in Table 1 and
Table 2 to paragraph (f) by clarifying the inner packaging quantity
limits for combination packages and added inner package limits for
certain Class 9 HMT entries consistent with the ICAO Technical
Instructions. When these amendments were added, PHMSA inadvertently
made a change that had not been proposed for comment to the Table 2
maximum authorized net capacity of each inner packaging for
transportation by cargo aircraft. Specifically, for packages containing
a net quantity of solids not greater than 15 kg, PHMSA made a change to
the maximum authorized net capacity for metal or plastic inner
packagings. Prior to publication of HM-215P, the HMR authorized 2.5 kg
consistent with the ICAO Technical Instructions. As it currently reads
in the HMR, the maximum authorized net capacity of each inner packaging
for metal or plastic inner packagings is 1 kg--which is incorrect--
which is now a source of confusion and disharmony with international
air transport regulations. Therefore, PHMSA is correcting this error by
revising 1 kg back to 2.5 kg. In addition, PHMSA is removing the
``periods'' in the third column of Table 2 for consistency with the
first and second columns, which do not have periods associated with the
information presented in those columns.
Section 173.62
    This section provides specific packaging requirements for
explosives. In HM-215B,\24\ RSPA amended the HMR to maintain alignment
with corresponding provisions of international standards. Prior to
final rule HM-215B, ``UN0485, Substances, explosive, n.o.s., 1.4G'' was
included in the table and assigned packing instruction E-103 in the
HMR, which required packagings to be determined by

a competent authority approval. However, RSPA inadvertently omitted
this material from the revised Explosives Table. Therefore, PHMSA is
amending Table 1 to Paragraph (b): Explosive Table to include an entry
for ``UN0485'' and assign it packing instruction 101, requiring
competent authority approval, consistent with the packing instruction
assigned prior to the inadvertent omission and with international
standards.

Section 173.185
    This section provides the requirements for packing and hazard
communication of lithium cells and batteries. The HMR includes use of
the phrase ``assemblies of such batteries'' in Sec.  173.185(b)(5) and
(e)(5). However, we neither define this phrase nor does it have
substantive meaning associated with the requirements for lithium
batteries weighing 12 kg or more. Furthermore, use of this terminology
was recently removed from the UN Model Regulations. To avoid confusion
as to its intended meaning and to maintain consistency with
international standards, PHMSA is amending Sec.  173.185(b)(5) and
(e)(5) by removing this language.
    For Sec.  173.185(c)(3), the title of (c)(3) ``Hazard
communication,'' is no longer considered appropriate for the content of
this paragraph. Paragraph (c)(3) covers the requirements for applying
the lithium battery mark. Moreover, there are other hazard
communication requirements that may apply besides those listed in Sec.
173.185(c)(3), such as the requirements listed in Sec.
173.185(c)(1)(iii) and (c)(1)(iv), which provide additional marking
requirements for a lithium battery. Therefore, PHMSA is amending the
title of Sec.  173.185(c)(3) to read ``Lithium battery mark'' for a
simpler understanding of the subject of this paragraph.
    Section 173.185(d) provides limited exceptions from transportation
requirements for lithium cells or batteries that are being shipped for
disposal or recycling. However, the paragraph is not formatted to list
each condition for exception as other similar paragraphs in the section
and HMR. Therefore, to clarify the conditions for exception, PHMSA is
amending Sec.  173.185(d) by revising the paragraph to list each
condition for transportation of a lithium cell or battery being shipped
for disposal or recycling.
Section 173.225
    This section provides packaging requirements and other provisions
for organic peroxides. In final rule HM-215N,\25\ PHMSA amended the HMR
to maintain consistency with international regulations and standards.
Specifically, to maintain consistency with UN Model Regulations, PHMSA
amended several entries and corrected formatting errors in the Organic
Peroxide Table in paragraph (c). As part of these revisions, the entire
table was reproduced in final rule HM-215N. However, in reproducing the
entire table, for many entries, the ``+'' symbol was inadvertently
removed from Column 7 in the table. Column 7 specifies the control and
emergency temperatures to be maintained for the listed material while
it is in transportation. Without the ``+'' by the number provided in
the column, a reader would be unable to determine for certain the
required control and emergency temperatures. For example, for ``UN3115,
tert-Amyl peroxy-2-ethylhexanoate,'' without a ``+'' in front of the
``20'' for the control temperature, one is not certain whether that is
meant to be -20[deg]C or +20[deg]C. Therefore, PHMSA is adding the
``+'' symbol to specific entries in the table that were inadvertently
removed under HM-215N to ensure clear understanding of the required
control and emergency temperatures. This amendment will enhance safety
by ensuring the proper control temperature is listed in the HMT.

Sections 173.244 and 173.314
    This section provides the requirements for bulk packagings for
certain pyrophoric liquids (Division 4.2), dangerous when wet materials
(Division 4.3), and poisonous liquids with inhalation hazards (Division
6.1). Section 173.314 provides requirements for compressed gases in
tank cars. In Sec.  173.31(e)(4), which provides special requirements
for use of rail tank cars for PIH material, the HMR provides a phase-
out for the use of legacy tank cars where a tank car not meeting the
requirements of Sec. Sec.  173.244(a)(2) or (a)(3) and 173.314(c) or
(d) may not be used for the transportation of PIH material. In final
rule HM-219C,\26\ PHMSA amended the HMR in response to petitions for
rulemaking submitted by the regulated community, including a petition
to adopt the phase-out date now found in Sec.  173.31(e)(4). PHMSA
revised the phase-out deadline for all non-HM-246 \27\ rail tank cars
used for the transportation of PIH materials to December 31, 2027.
However, although PHMSA adopted the phase-out date in Sec.
173.31(e)(4), we did not include a reference to the phase-out deadline
in Sec. Sec.  173.244(a)(2) and 173.314(c)--Note 11 to Table 1, which
has become a source of confusion. Therefore, to make clear the
applicability of the phase-out date, PHMSA will make a reference to the
phase-out date of December 31, 2027, in Sec. Sec.  173.244(a)(2) and
173.314(c)--Note 11 to Table 1. In addition, PHMSA will make a
reference in Note 11 to Table 1 regarding use of those tanks built
after March 16, 2009. Finally, PHMSA is correcting grammatical and
formatting issues in the Sec.  173.314--Notes to Table 1 to paragraph

Section 173.301
    This section provides the general requirements for the shipment of
compressed gases and other hazardous materials in cylinders, UN
pressure receptacles, and spherical pressure vessels. Section
173.301(f)(5) provides instruction on when a pressure relief device is
not required and specifies four options. The word ``or'' following
paragraph (f)(5)(ii) and prior to (f)(5)(iii) is misplaced and should
follow (f)(5)(iii) instead. Otherwise, it can be misunderstood that
paragraph (f)(5)(iv) applies in addition to one of the first three
options, which is not the case. Therefore, PHMSA is amending Sec.
173.301(f)(5) by moving the word ``or'' between Sec. Sec.
173.301(f)(5)(iii) and (iv) to ensure that it is understood that each
option in the list is a standalone alternative compliance approach. In
addition, PHMSA is correcting a typographical error in Sec.
173.301(f)(5)(iv) where we are replacing the second ``or'' before the
word ``this'' with the word ``of.''
Section 173.303
    This section provides the requirements for charging cylinders with
acetylene gas in solution. There is a typographical error in Sec.
173.303(f)(1)(i) where the Euro sign ``[euro]'' is listed after the
first reference to ISO 3807:2013 instead of an uppercase ``(E).''
Therefore, PHMSA is revising this document reference to read as the
following: ``ISO 3807:2013(E).''
Section 173.304a
    This section provides additional requirements for the shipment of
liquefied compressed gases in DOT specification cylinders. Table 1 to
Paragraph (a)(2), ``Methyl acetylene-propadiene, mixtures,
stabilized,'' has a maximum permitted filling density (percent) listed
as ``not liquid at 130 [deg]F,'' which is in error because the filling
density requirement describes how full the cylinder may be and not
whether the

contents are in a liquid or gaseous state. In addition, ``Methyl
acetylene-propadiene, mixtures, stabilized,'' is listed differently in
the HMT as opposed to how it is listed in Table 1. In the notice of
proposed rulemaking for HM-220D,\28\ RSPA proposed to amend the HMR by
revising the requirements for hazardous materials that are authorized
to be offered for transportation in cylinders. When RSPA proposed
changes to the table to Sec.  173.304a(a)(2), ``Methyl acetylene-
propadiene, mixtures, stabilized,'' was listed with the appropriate
filling density instruction of ``not liquid full at 130 [deg]F.''
However, in final rule HM-220D,\29\ RSPA inadvertently changed the
filling density requirement to read ``not liquid at 130 [deg]F.''
Moreover, in the final rule, in response to appeals, HM-220D,\30\ RSPA
revised the filling density temperature requirements from ``54 [deg]C
(130 [deg]F)'' to ``55 [deg]C (131 [deg]F)'' for uniformity purposes
with other sections, but still kept the language ``Not liquid at.''
Therefore, PHMSA is amending the maximum permitted filling density
instruction for ``Methyl acetylene-propadiene, mixtures, stabilized''
to read ``Not liquid full at 131 [deg]F.'' Furthermore, for consistency
with the how the entry for the material reads in the HMT, PHMSA is
revising ``Methyl acetylene-propadiene, mixtures, stabilized'' to read
``Methyl acetylene and propadiene mixtures, stabilized.''

missing from the current entry ``OT-4B240.'' PHMSA is correcting this
error by adding the missing letter so that the cylinder specification
reads correctly as ``DOT-4B240.'' Finally, PHMSA is correcting
grammatical errors in the notes to Table 1 to Paragraph (a)(2). For
example, in Note 2, we are adding a period to the abbreviation for
pound (lb.).
Section 173.313
    This section provides the UN portable tank table for liquefied
compressed gases and chemicals under pressure. In final rule HM-
215G,\31\ RSPA amended the HMR to maintain alignment with international
standards. Specifically, the rule relocated the design and use
requirements for portable tanks in liquefied compressed gases and
chemical under pressure service--previously found in Sec.
172.102(c)(7) Special Provisions--to Sec.  173.313 ``UN Portable Tank
Table for Liquefied Compressed Gases and Chemical Under Pressure.'' In
its explanation of those changes, PHMSA stated, ``The table provides
the maximum allowable working pressures, bottom opening requirements,
and degree of filling requirements for liquefied compressed gases
permitted for transport in portable tanks.'' This language is confusing
because the table includes a ``minimum design pressure (in bar)''
requirement -- a minimum design value distinguishable from the maximum
allowable working pressure (MAWP) value. The minimum design pressure
relates to the pressure the portable tank should be exposed to under
normal conditions based on factors like material of construction and
thickness of the material. The MAWP is the maximum pressure at which
the portable tank would be allowed to function at a specific
temperature and considers the design pressure. Therefore, PHMSA is
amending Sec.  173.313 introductory language by adding the term
``minimum design pressure'' in the header of the third column of the
table.

Section 173.315
    This section provides the requirements for compressed gases in
cargo tanks and portable tanks. In final rule HM-245,\32\ PHMSA adopted
the provisions of DOT-SP 13341 into the HMR, which allowed storage
containers (of 500 gallons or less water capacity) intended to be
permanently installed on a consumer's premises to be transported
charged with liquefied petroleum gas (LPG) in quantities greater than
five percent of the container's water capacity. Furthermore, the
special permit authorized one-way transportation only from the
consumer's location to the container owner's nearest LPG facility. In
HM-245, PHMSA revised paragraph (j) to allow these designated storage
containers under specific conditions. However, PHMSA mistakenly created
Sec.  173.315(j)(3) which states: ``Storage containers of less than
1,042 pounds water capacity (125 gallons) may be shipped when charged
with liquefied petroleum gas in compliance with DOT filling density.''
This specific language should have been one of the conditions under
Sec.  173.315(j)(1), and not a standalone provision as (j)(3).
Therefore, PHMSA is amending Sec.  173.315(j) by redesignating
paragraph (j)(3) as paragraph (j)(1)(iv) and removing and reserving
Sec.  173.315(j)(3).

F. Part 174

Section 174.5
    This section provides the requirements for a rail carrier's
materials and supplies. In the second sentence, it states: ``The
requirements of this subchapter do not apply to railway torpedoes or
fusees when carried in engines or rail cars.'' The use of the term
``fusees'' is an industry term used to describe railroad safety flares.
For simplicity and understanding of what a fusee is, PHMSA is revising
the second sentence, to read as follows, ``The requirements of this
subchapter do not apply to railway torpedoes or railroad safety flares
(i.e., fusees) when carried in engines or rail cars.''
Section 174.55
    This section provides general handling and loading requirements by
rail. In Sec.  174.55(a)--specifically, regarding the last sentence
providing examples of blocking and bracing in freight containers and
transport vehicles--PHMSA had intended to amend this section in final
rule HM-218F \33\ by removing reference to the Bureau of Explosives
(BOE) Pamphlet Nos. 6 and 6C and to replace them with ``the Intermodal
Loading Guide for Products in Closed Trailers and Containers'' as is
listed in Table 1 to Sec.  171.7--Materials Not Incorporated by
Reference. However, only the reference to BOE Pamphlet No. 6C was
removed and the reference to BOE Pamphlet No. 6 remains. Furthermore,
Sec.  171.19 states ``Effective December 31, 1998, approvals or
authorizations issued by the Bureau of Explosives (BOE), other than
those issued under part 179 of this subchapter, are no longer valid.''
Any reference to BOE Pamphlet Nos. 6 and 6C should have been removed
from Sec.  174.55(a). For consistency and to avoid confusion, PHMSA is
removing the reference to BOE Pamphlet No. 6 in paragraph (a) as well
as the ``IBR'' reference because the intermodal loading guide is not a
material incorporated by reference. The last sentence of the paragraph
is revised to read the following: ``For examples of blocking and
bracing in freight containers and transport vehicles, see the
Intermodal Loading Guide for Products in Closed Trailers and Containers
(see Table 1 to Sec.  171.7 of this subchapter).''
---------------------------------------------------------------------------

    \33\ 76 FR 43510 (Jul. 20, 2011)

---------------------------------------------------------------------------

Section 174.67
    This section provides the requirements for transloading operations
by rail. The second sentence of Sec.  174.67(a)(3) states in reference
to securing access to railroad track: ``This requirement may be
satisfied by lining each switch providing access to the unloading area
against shifting and securing each switch with an effective locking
device, or by using derails, portable bumper blocks, or other equipment
that provides an equivalent level of safety.'' Use of the term
``shifting'' (as it applies to packages shifting in a freight
container) in the context of securing access to the track has been a
source of confusion among stakeholders. In final rule HM-260A,\34\
PHMSA amended the HMR by clarifying the use of the term ``movement''
which, by definition in Sec.  171.8, means the physical transfer of a
hazardous material from one geographical location to another by rail,
car, aircraft, motor vehicle, or vessel. Moreover, PHMSA explained that
the term ``movement'' was not used appropriately regarding train
securement and the safe handling or stowage of packages. PHMSA revised
each instance of ``movement'' to either ``shifting'' or ``motion'' (as
it applies to motion of rail cars on a track) where appropriate.
However, when making changes to Sec.  174.67(a)(3) in HM-260A, PHMSA
inadvertently replaced the term ``movement'' with ``shifting'' instead
of replacing the term ``movement'' with ``motion'' as explained in the
discussion section ``Clarifying the Use of the Term ``Movement'' Within
the HMR.'' Therefore, PHMSA is correcting this error by replacing the
term ``shifting'' with the term ``motion'' to accurately represent the
securement of the train on a rail track.

    \34\ 85 FR 83366 (Dec. 21, 2020).
---------------------------------------------------------------------------

Section 174.101
    This section provides the requirements for loading Class 1
(explosive) materials by rail. Section 174.101(h) provides instruction
that for recommended methods of blocking and bracing, to see Bureau of
Explosives Pamphlets No. 6 and 6A. PHMSA no longer recognizes these BOE
pamphlets as sources for blocking and bracing methods for rail
transportation, but instead references ``The Intermodal Loading Guide
for Products in Closed Trailers and Containers'' listed in Table 1 to
Sec.  171.7--Materials Not Incorporated by Reference. Therefore, to
ensure appropriate reference to blocking and bracing methods for safe
rail transport, PHMSA is amending this section by removing the
reference to BOE Pamphlet Nos. 6 and 6A in paragraph (h) and revising
the third sentence to read as follows: ``For recommended methods of
blocking and bracing, see the Intermodal Loading Guide for Products in
Closed Trailers and Containers (see Table 1 to Sec.  171.7 of this
subchapter).''
Section 174.112
    This section provides the requirements for loading Division 1.3 and
Division 1.2 explosive materials by rail. In Sec.  174.112(b), the last
sentence of the paragraph states: ``For recommended methods of blocking
and bracing see Bureau of Explosives Pamphlet No. 6.'' This reference
is incorrect as PHMSA no longer recognizes this pamphlet. Rather, the
recommended methods for blocking and bracing when transported by rail
are in ``The Intermodal Loading Guide for Products in Closed Trailers
and Containers,'' which is listed in Table 1 to Sec.  171.7--Materials
Not Incorporated by Reference. Therefore, PHMSA is amending paragraph
(b) by removing the reference to BOE Pamphlet No. 6 and revising the
last sentence to the following: ``For recommended methods of blocking
and bracing see the Intermodal Loading Guide for Products in Closed
Trailers and Containers (see Table 1 to Sec.  171.7 of this
subchapter).'' This amendment will ensure safe rail transport through
recognized and recommended blocking and bracing methods.
Section 174.115
    This section provides the requirements for loading Division 1.4
(explosive) material by rail. In Sec.  174.115(a), the last sentence of
the paragraph states: ``For methods of recommended loading and bracing
see Bureau of Explosives Pamphlet No. 6.'' This reference is incorrect
as PHMSA no longer recognizes this pamphlet. The methods for loading
and bracing when transported by rail are located in ``The Intermodal
Loading Guide for Products in Closed Trailers and Containers,'' which
is listed in Table 1 to Sec.  171.7--Materials Not Incorporated by
Reference. Therefore, PHMSA is removing the reference to BOE Pamphlet
No. 6 in paragraph (a) and revising the last sentence of the paragraph
to the following: ``For methods of recommended loading and bracing see
the Intermodal Loading Guide for Products in Closed Trailers and
Containers (see Table 1 to Sec.  171.7 of this subchapter).'' This
amendment will ensure safe rail transport through use of recognized and
recommended methods of blocking and bracing.
Section 174.290
    This section provides the requirements for the rail transportation
of materials extremely poisonous by inhalation shipped by, for, or to
the Department of Defense. Section 174.290(h), references Sketch 1 in
BOE Pamphlet No. 6. However, BOE Pamphlet No. 6 is no longer recognized
by PHMSA as a valid source ``not incorporated by reference'' in Sec.
171.7. Therefore, PHMSA is deleting reference to Sketch 1 to avoid
confusion that BOE Pamphlet 6 is a source for proper methods of loading
and bracing in paragraph (h).
    Also, Sec.  174.290(i), references Sketch 1 in BOE Pamphlet No. 6A.
However, BOE Pamphlet No. 6A is also no longer recognized by PHMSA.
Therefore, PHMSA is deleting the reference to Sketch 1 to avoid
confusion that BOE Pamphlet 6A is a resource for proper methods of
protecting doorways in paragraph (i).

G. Part 175

Section 175.1
    This section provides the purpose, scope, and applicability of the
HMR for the transportation of hazardous materials in commerce aboard an
aircraft. There is a grammatical error in the section title in that a
comma is missing after the word ``scope.'' Additionally, in the first
sentence of paragraph (a), the word ``the'' is missing before the word
``requirements'' and the word ``an'' is missing before the word
``aircraft.'' Therefore, for improved readability and grammar, PHMSA is
revising the title to Sec.  175.1 and revising paragraph (a) to correct
these errors. Additionally, there is an error in the second sentence of
paragraph (b) where the first use of the term ``subchapter'' is
incorrect in referencing applicability to persons performing functions
subject to the subchapter. The term ``part'' should be used instead as
in ``this part (i.e., part 175--Carriage by Aircraft) applies to any
person who performs, attempts to perform, or is required to perform any
function subject to this subchapter.'' Therefore, in the second
sentence of paragraph (b), PHMSA is replacing the first use of
``subchapter'' with ``part.''
Section 175.9
    This section provides the requirements for special aircraft
operations. There is a typographical error in the first sentence of
paragraph (a). It states: ``This subchapter applies to rotorcraft
external load operations transporting hazardous material on board,
attached to, or suspended from an aircraft.'' The use of the term

``subchapter'' is incorrect and instead, it should state ``section.''
PHMSA is replacing the term ``subchapter'' with the term ``section'' as
appropriate.
    Furthermore, paragraph (b) provides exceptions from HMR oversight.
In final rule HM-218H,\35\ PHMSA amended the HMR to make miscellaneous
amendments to update and clarify certain regulatory requirements. One
of the amendments made in Sec.  175.9 was the removal of paragraph
(b)(4), which excepted hazardous materials carried and used during
dedicated air ambulance, firefighting, or search and rescue operations
from being subject to the HMR when in compliance with applicable
Federal Aviation Regulations (14 CFR) and any additional FAA
requirements. At that time, PHMSA inserted paragraph (d) into Sec.
175.1 with language to clarify that these types of air operations would
otherwise be subject to the requirements in the HMR. However, the above
revision left in place made an additional reference to an exception for
firefighting and prevention, among other activities, in Sec.
175.9(b)(6). The inclusion of firefighting and prevention in this
exception is redundant because this aircraft operation activity is
already covered under Sec.  175.1(d) as not being subject to the HMR.
Therefore, PHMSA is revising paragraph (b)(6) by removing reference to
firefighting and prevention.

    \35\ 81 FR 35484 Jun. 2, 2016).
---------------------------------------------------------------------------

H. Part 177

Section 177.817
    This section provides the requirements for shipping papers for
hazardous materials transported by highway. Section 177.817(d) states:
``This subpart does not apply to a material that is excepted from
shipping paper requirements as specified in Sec.  172.200 of this
subchapter.'' The use of the term ``subpart'' is not the most
appropriate reference, as this would imply a hazardous material, which
is excepted from shipping papers, would not be subject to all of
subpart A of part 177. The appropriate term is ``section'' because the
section prescribes the requirements for shipping papers for highway
transportation; therefore, PHMSA is revising Sec.  177.817(d) to read
as follows: ``This section does not apply to a material that is
excepted from shipping paper requirements as specified in Sec.  172.200
of this subchapter.'' This amendment will ensure proper shipping papers
and hazard information available for only the limited exception
outlined in the section, which will support safe transportation of such
hazardous materials.
Section 177.842
    This section provides the requirements for Class 7 (radioactive)
material transported by highway. Section 177.842(b)(2) provides
instruction for the placement of certain radioactive material packages
in a transport vehicle, storage location or in any other place
according to the table found in paragraph (b)(2). Paragraph (b)(2)
provides further instruction on how to handle and stow groups of
packages when more than one is present in a storage location.''
However, the term ``stowed'' as used in paragraph (b)(2) is typically
associated with vessel transport and not highway transport. The term
``stowage'' is defined in Sec.  171.8 and means placing hazardous
materials aboard a vessel and therefore, may be a source of confusion
in this paragraph. PHMSA believes ``stored'' is the more appropriate
term to use in the context of groups of packages present in one storage
location. Therefore, PHMSA is revising the second sentence of Sec.
177.842(b)(2) to the following: ``Each group of packages must be
handled and stored together no closer than 6 m (20 feet) (measured edge
to edge) to any other group. The following table is to be used in
accordance with the provisions of paragraph (b) of this section:'' This
amendment will alleviate any confusion on the method of transportation
referenced and ensure safe transport of such radioactive material.
Section 177.848
    This section provides the requirements for segregation of hazardous
materials transported by highway. Specifically, Sec.  177.848(e)(6)
provides instruction for segregation of packages that display a
subsidiary hazard label and uses the term ``stowed'' in the context of
hazardous materials of the same class. However, the term ``stowed'' is
typically associate with vessel transportation. Section 171.8 defines
the term ``stowage'' as placing hazardous materials aboard a vessel.
Furthermore, throughout every paragraph within Sec.  177.848, the
language ``loaded, transported, or stored together'' is used.
Therefore, consistent with this language, PHMSA believes use of the
term ``stored'' in Sec.  177.848(e)(6) is more appropriate than
``stowed'' and is revising the second sentence of Sec.  177.848(e)(6)
accordingly. This amendment will alleviate any confusion regarding the
method of transport applicable to this section.

I. Part 178

Section 178.50
    This section provides the requirements for specification 4B welded
or brazed steel cylinders. In final rule HM-220B,\36\ RSPA amended the
HMR by restructuring the cylinder specification requirements. The goal
of the restructuring was to eliminate unnecessary pages within the HMR
without substantially changing the regulatory requirements or affecting
safety. Furthermore, the restructuring focused on these specific goals:
(1) consolidating similar sections, (2) reformatting subpart C of part
178, and (3) revising section references throughout the HMR to
correspond to revised sections. However, when RSPA restructured part
178, the language in Sec.  178.50(a) was inadvertently changed and in
doing so, gave the appearance that all specification 4B cylinders must
have a longitudinal seam whereas the language in Sec.  178.50(a) prior
to HM-220B provided for specifications when cylinders have longitudinal
seams. In addition, PHMSA issued a letter of interpretation \37\
explaining this error and that PHMSA would correct the error in a
future rulemaking. Therefore, PHMSA is revising the language from Sec.
178.50(a) to be consistent with manufacturing of these cylinders where
not all are made with longitudinal seams.

    \37\ Letter of Interpretation (Ref No. 15-0062).
---------------------------------------------------------------------------

Section 178.337-1
    This section provides the general requirements for specification MC
331 cargo tank motor vehicles. There is a typographical error in Sec.
178.337-1(f) in the last sentence of the paragraph. It states: ``The
post weld heat treatment must be as prescribed in Section VIII of the
ASME Code, but in no event at less than 1,050 Sec.  F cargo tank metal
temperature.'' The section symbol ``Sec.  '' should instead read as the
degree sign ``[deg].'' Therefore, PHMSA is revising this last sentence
of paragraph (f) to include the temperature with the degree sign--1,050
[deg]F.
Section 178.338-10
    This section provides the accident damage protection requirements
for specification MC-338 cargo tank motor vehicles. There is a
typographical error in Sec.  178.338-10(c)(2) where it states:
``Conform to the requirements of Sec.  178.345-8(b).'' This is
incorrect as Sec.  178.345-8(b) is related to outlets for specification
DOT 406, DOT 407, and DOT 412 cargo tank motor vehicles and

not accident damage protection for specification MC-338 cargo tank
motor vehicles. To clarify the correct citation, PHMSA is removing the
reference to paragraph (b) and changing it to paragraph (d).
Section 178.601
    This section provides the general requirements for specification
packagings. The last sentence of Sec.  178.601(g)(2)(vi) states, ``For
packagings containing liquids, the absorbent material required in
paragraph (g)(2)(v) of this section must be placed inside the means of
containing liquid contents.'' The word ``as'' is missing before the
second use of the word ``the'' that would give clearer context of the
requirement that absorbent material required for packagings containing
liquids must be placed inside as the means of containing the liquid
contents rather than placing it inside the means of containing the
liquid. Therefore, PHMSA is adding ``as'' to the sentence to read,
``For packagings containing liquids, the absorbent material required in
paragraph (g)(2)(v) of this section must be placed inside as the means
of containing liquid contents.''

J. Part 180

Section 180.507
    This section provides the requirements for the qualification of
tank cars. With regard to Sec.  180.507(b), the title of paragraph (b),
``Tank car specifications no longer authorized for construction'' is
misleading and a source of confusion as the title would imply that all
specifications that follow in the paragraph are no longer authorized
for construction, which is not the case. Rather, what follows is a
table of tank car specifications that are no longer authorized for
construction but allowed to remain in hazardous materials service if
the tank cars adhere to the requirements of the HMR. Therefore, PHMSA
is amending Sec.  180.507(b)(1) to clarify that the tank specifications
are no longer authorized, but tank cars built to the specifications may
remain in hazardous materials service as long the requirements of the
HMR are met. Additionally, PHMSA is amending the table in Sec.
180.507(b)(1) to remove the very old ICC-105, 105A300, 105A400,
105A500, 105A600, ICC-27, BE-27, 106A500, and 106A800 specifications.
These outmoded tanks were last authorized for construction over 50
years ago and are no longer in use in North America. Therefore, for
clarity, we are removing these specifications from the table, as they
would no longer be authorized for service. Similarly, we are removing
Note 2, as no DOT-107A seamless steel tanks constructed between January
1, 1941, and December 31, 1955, are in service today.
Section 180.605
    This section provides the requirements for periodic testing,
inspection, and repair of portable tanks. Section 180.605(b)(5)
provides one of five specified conditions that would require testing
and inspection of a portable tank and states, ``The portable tank is in
an unsafe operating condition based on the existence of probable
cause.'' The terminology ``probable cause'' is typically reserved for
criminal law and is inappropriate within the scope of conditions
necessitating testing and inspection of a portable tank. Rather, the
focus should be on the determination of unsafe operating conditions.
Therefore, PHMSA is amending Sec.  180.605(b)(5) by revising this
paragraph to read, ``The portable tank is in an unsafe operating
condition.''

V. Regulatory Analyses and Notices

A. Statutory/Legal Authority for This Rulemaking

    This final rule is published under the authority of the Federal
Hazardous Materials Transportation Act (HMTA; 49 U.S.C. 5101-5127).
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.'' The Secretary has delegated the authority granted in the
HMTA to the PHMSA Administrator at 49 CFR 1.97(b).
    PHMSA finds it has good cause to make these changes 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
editorial and ministerial amendments to these regulations make no
substantive changes to the regulations, but merely facilitate further
compliance with the existing regulations by correcting information
(e.g., mailing addresses) and otherwise providing increased clarity for
certain provisions.

B. Executive Order 12866 and DOT Regulatory Policies and Procedures

    Executive Order 12866 (``Regulatory Planning and Review'') \38\
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.'' Similarly, DOT regulations
require that regulations issued by PHMSA and other DOT Operating
Administrations ``should be designed to minimize burdens and reduce
barriers to market entry whenever possible, consistent with the
effective promotion of safety'' and should generally ``not be issued
unless their benefits are expected to exceed their costs.'' This final
rule does not impose new burdens as the amendments contained in this
final rule are non-substantive changes that do not impose new
requirements for hazardous materials shippers or carriers. Therefore,
it is not necessary to prepare a regulatory impact analysis.
---------------------------------------------------------------------------

    \38\ 58 FR 51735, (Oct. 4, 1993).
---------------------------------------------------------------------------

    This final rule is not a significant regulatory action under
section 3(f) of Executive Order 12866 and, therefore, was not reviewed
by the Office of Management and Budget. Nor is this final rule
considered a significant rulemaking under the DOT rulemaking procedures
at 49 CFR part 5.

C. Executive Order 13132

    This final rule has been analyzed in accordance with the principles
and criteria in Executive Order 13132 (``Federalism'') \39\ and its
implementing Presidential Memorandum (``Preemption'').\40\ 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.''
---------------------------------------------------------------------------

    \39\ 64 FR 43255 (Aug. 10, 1999).
    \40\ 74 FR 24693 (May 22. 2009).
---------------------------------------------------------------------------

    The HMR amendments in this final rule are non-substantive changes
that do not impose any new requirements and will not have 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. Nor do the HMR
amendments in this final rule impose direct compliance costs on state
and local governments. Therefore, the

consultation and funding requirements of Executive Order 13132 do not
apply.

D. Executive Order 13175

    PHMSA analyzed this final rule in accordance with the principles
and criteria contained in Executive Order 13175 (``Consultation and
Coordination with Indian Tribal Governments'') \41\ and DOT Order
5301.1, ``Department of Transportation Policies, Programs, and
Procedures Affecting American Indians, Alaska Natives, and Tribes.''
---------------------------------------------------------------------------

    \41\ 65 FR 67249 (Nov. 9, 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
does not significantly or uniquely affect tribal communities or Native
American Tribal governments. The changes to the HMR as written in this
final rule are facially neutral and have broad, national scope; PHMSA
therefore expects this 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 this 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 finds the funding and
consultation requirements of Executive Order 13175 and DOT Order 5301.1
do not apply.

E. 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, where possible to
do so and still meet the objectives of applicable regulatory statutes.
Executive Order 13272 (``Proper Consideration of Small Entities in
Agency Rulemaking'') \42\ 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. The DOT posts its
implementing guidance on a dedicated web page.\43\
---------------------------------------------------------------------------

    \43\ DOT, ``Rulemaking Requirements Related to Small Entities,''
https://www.transportation.gov/regulations/rulemaking-requirements-concerning-small-entities (last accessed June 17, 2021).
---------------------------------------------------------------------------

    This final rule has been developed in accordance with Executive
Order 13272 and with DOT's procedures and policies to promote
compliance with the Regulatory Flexibility Act to ensure that potential
impacts of draft rules on small entities are properly considered. There
are no costs to small entities associated with this final rule. This
final rule makes non-substantive changes that do not impose new
requirements; thus, there are no direct or indirect adverse economic
impacts for small units of government, businesses, or other
organizations. Consequently, PHMSA certifies that this final rule does
not have a significant economic impact on a substantial number of small
entities.

F. 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 Federal regulatory
actions on state, local, and tribal governments, and the private
sector. For any NPRM or 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.
    This final rule does not impose unfunded mandates under the UMRA.
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.

G. 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. There are no new or modified
information collection requirements in this final rule.

H. Environmental Assessment

    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 this final rule is to introduce non-
substantive changes that do not impose new requirements. The intended
effect of this rule is to enhance the accuracy and reduce
misunderstandings of the regulations. Therefore, PHMSA has determined
that implementing this final rule will not significantly impact the
quality of the human environment.

I. Environmental Justice

    Executive Orders 12898 (``Federal Actions to Address Environmental
Justice in Minority Populations and Low-Income Populations''),\44\
13985 (``Advancing Racial Equity and Support for Underserved
Communities Through the Federal Government''),\45\ 13990 (``Protecting
Public Health and the Environment and Restoring Science To Tackle the
Climate Crisis''),\46\ 14008 (``Tackling the Climate Crisis at Home and
Abroad''),\47\ 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.
---------------------------------------------------------------------------

    \44\ 59 FR 7629 (Feb. 16, 1994).
    \45\ 86 FR 7009 (Jan. 20, 2021).
    \46\ 86 FR 7037 (Jan. 20, 2021).
    \47\ 86 FR 7619 (Feb. 1, 2021).
---------------------------------------------------------------------------

    PHMSA has evaluated this final rule under the above Executive
Orders and DOT Order 5610.2C and does 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 rulemaking is facially
neutral and national in scope; it is neither directed toward a
particular population, region, or community, nor is it expected to
impact any particular population, region, or community adversely.
Because PHMSA does not expect this final rulemaking to adversely affect
the safe transportation of hazardous materials generally, and because
the amendments in this final rule are non-substantive changes, PHMSA
does not expect the proposed revisions would entail disproportionately
high adverse risks for minority populations, low-income populations, or
other underserved and other disadvantaged communities.

J. Executive Order 13609 and International Trade Analysis

    Under Executive Order 13609 (``Promoting International Regulatory
Cooperation''),\48\ 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.
---------------------------------------------------------------------------

    \48\ 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) (as
amended, the Trade Agreements Act), prohibits federal agencies from
establishing any standards or engaging in related activities that
create unnecessary obstacles to the foreign commerce of the United
States. Pursuant to the Trade Agreements Act, the establishment of
standards is not considered an unnecessary obstacle to the foreign
commerce of the United States, 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 participates in establishing international standards to
protect the safety of the American public. PHMSA has assessed the
effects of the final rule to ensure that it does not cause unnecessary
obstacles to foreign trade. The amendments contained in this rule are
non-substantive changes and do not impose new requirements. Further,
insofar as many of the amendments introduced by the final rule improve
the clarity of the HMR for regulated entities or better align the HMR
with international (e.g., IAEA) standards, the final rule could reduce
barriers to international trade. Therefore, this final rule does not
present an obstacle to international trade, and accordingly, this final
rule is consistent with Executive Order 13609 and PHMSA's obligations
under the Trade Agreements Act.

    The revisions and additions read as follows:

Sec.  172.101  Purpose and use of hazardous materials table.

* * * * *
    (f) Column 5: Packing group. Column 5 specifies one or more packing
groups assigned to a material corresponding to the proper shipping name
and hazard class for that material. Class 2, Class 7, and Division 6.2
do not have packing groups. Articles in classes other than Class 1 are
not assigned to packing groups. For packing purposes, any requirement
for a specific packaging performance level is set out in the applicable
packing authorizations of part 173. Packing Groups I, II, and III
indicate the degree of danger presented by the material is great,
medium, or minor, respectively. If more than one packing group is
indicated for an entry, the packing group for the hazardous material is
determined using the criteria for assignment of packing groups
specified in subpart D of part 173. When a reevaluation of test data or
new data indicates a need to modify the specified packing group(s), the
data should be submitted to the Associate Administrator. Each reference
in this column to a material that is a hazardous waste or a hazardous
substance, and whose proper shipping name preceded in Column 1 of the
Table by the letter ``A'' or ``W,'' is modified to read ``III'' on
those occasions when the material is offered for transportation or
transported by a mode in which its transportation is not otherwise
subject to requirements of this subchapter.
* * * * *
    (i) * * *
    (3) Bulk packaging. Column (8C) specifies the section in part 173
of this subchapter that prescribes packaging requirements for bulk
packagings, subject to the limitations, requirements, and additional
authorizations of Columns (7) and (8B). A ``None'' in Column (8C) means
bulk packagings are not authorized, except as may be provided by
special provisions in Column (7) and in packaging authorizations Column
(8B). Additional authorizations and limitations for use of UN portable
tanks are set forth in Column 7. For each reference in this column to a
material that is a hazardous waste or a hazardous substance, and whose
proper shipping name is preceded in Column 1 of the Table by the letter
``A'' or ``W'' and that is offered for transportation or transported by
a mode in which its transportation is not otherwise subject to the
requirements of this subchapter:
    (i) The column reference is Sec.  173.240 or Sec.  173.241, as
appropriate.
    (ii) For a solid material, the exception provided in special
provision B54 is applicable.
    (iii) For a Class 9 material, which meets the definition of an
elevated temperature material, the column reference is Sec.  173.247.
