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as well as outdated concepts such as other regulated materials-domestic 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 Removing Outdated References to Other Regulated Materials-Domestic 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.

[[Page 79754]]

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

[[Page 79755]]

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:

     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.
     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

[[Page 79756]]

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 . . .

[[Page 79757]]

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

[[Page 79758]]

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.

    \24\ 87 FR 24690 (May 6, 1997).
---------------------------------------------------------------------------

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

[[Page 79759]]

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.''

    Also, in Table 1 to Paragraph (a)(2), Column 3 provides the 
authorized packagings for listed hazardous material. For ``Methyl 
mercaptan,'' there is a typographical error where the letter ``D'' is 
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).''

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

[[Page 79761]]

``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.

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

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

[[Page 79762]]

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.''

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

    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

[[Page 79763]]

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\
---------------------------------------------------------------------------

    \42\ 68 FR 7990 (Feb. 19, 2003).
    \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

[[Page 79764]]

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.

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.

    Note 1 to paragraph (a)(2): ``Filling density'' means the 
percent ratio of the weight of gas in a packaging to the weight of 
water that the container will hold at 16 [deg]C (60 [deg]F). (1 lb. 
of water = 27.737 in\3\ at 60 [deg]F).


    Note 2 to paragraph (a)(2): Cylinders purchased after Oct. 1, 
1944, for the transportation of chlorine must contain no aperture 
other than that provided in the neck of the cylinder for attachment 
of a valve equipped with an approved pressure relief device. 
Cylinders purchased after November 1, 1935, and filled with chlorine 
may not contain over 68.04 kg (150 lb.) of gas.


    Note 4 to paragraph (a)(2): Special carbon dioxide mining 
devices containing a heating element and filled with not over 2.72 
kg (6 lb.) of carbon dioxide may be filled to a density of not over 
85 percent, provided the cylinder is made of steel with a calculated 
bursting pressure in excess of 39,000 psig, fitted with a frangible 
disc that will operate at not over 57 percent of that pressure, and 
is able to withstand a drop of 10 feet when striking crosswise on a 
steel rail while under a pressure of at least 3,000 psig. Such 
devices must be shipped in strong boxes or must be wrapped in heavy 
burlap and bound by 12-gauge wire with the wire completely covered 
by friction tape. Wrapping must be applied so as not to interfere 
with the functioning of the frangible disc pressure relief device. 
Shipments must be described as ``liquefied carbon dioxide gas 
(mining device)'' and marked, labeled, and certified as prescribed 
for liquefied carbon dioxide.


    Note 5 to paragraph (a)(2): All parts of the valve and pressure 
relief devices in contact with contents of cylinders must be of a 
metal or other material, suitably treated, if necessary, that will 
not cause the formation of any acetylides.


    Note 7 to paragraph (a)(2): Specification 3HT cylinders for 
aircraft use only, having a maximum service life of 24 years. 
Authorized only for nonflammable gases. Cylinders must be equipped 
with pressure relief devices of the frangible disc type that meet 
the requirements of Sec.  173.301(f). Each frangible disc must have 
a rated bursting pressure that does not exceed 90 percent of the 
minimum required test pressure of the cylinder. Discs with fusible 
metal backing are not permitted. Cylinders may be offered for 
transportation only when packaged in accordance with Sec.  
173.301(a)(9).


    Note 8 to paragraph (a)(2): See Sec.  173.301(a)(9).


    Note 9 to paragraph (a)(2): When used for shipment of flammable 
gases, the internal volume of a specification 39 cylinder must not 
exceed 75 cubic inches.


    Note 10 to paragraph (a)(2): Each valve outlet must be sealed by 
a threaded cap or a threaded solid plug.


    Note 11 to paragraph (a)(2):  Must meet the valve and cleaning 
requirements in Sec.  173.302(b).


    Note 12 to paragraph (a)(2):  For an insecticide gas that is

    (c) * * *

Table 1 to Paragraph (c)

* * * * *

    Notes to table 1 to paragraph (c):  1. The filling density 
percentage for liquefied gases is hereby defined as the percent 
ratio of the mass of gas in the tank to the mass of water that the 
tank will hold. For determining the water capacity of the tank in 
kilograms, the mass of 1 L of water at 15.5 [deg]C in air is 1 kg 
(the mass of one gallon of water at 60 [deg]F in air is 8.32828 
pounds).
    2. The liquefied gas must be loaded so that the outage is at 
least two percent of the total capacity of the tank at the reference 
temperature of 46 [deg]C (115 [deg]F) for a non-insulated tank; 43 
[deg]C (110 [deg]F) for a tank having a thermal protection system 
incorporating a metal jacket that provides an overall thermal 
conductance at 15.5 [deg]C (60 [deg]F) of no more than 10.22 
kilojoules per hour--per square meter--per degree Celsius (0.5 Btu 
per hour/per square foot/per degree F) temperature differential; and 
41 [deg]C (105 [deg]F) for an insulated tank having an insulation 
system incorporating a metal jacket that provides an overall thermal 
conductance at 15.5 [deg]C (60 [deg]F) of no more than 1.5333 
kilojoules per hour--per square meter--per degree Celsius (0.075 Btu 
per hour/per square foot/per degree F) temperature differential.
    3. The requirements of Sec.  173.24b(a) apply.
    4. The gas pressure at 54.44 [deg]C (130 [deg]F) in any non-
insulated tank car may not exceed 7/10 of the marked test pressure, 
except that a tank may be charged with helium to a pressure of 10 
percent in excess of the marked maximum gas pressure at 54.44 [deg]C 
(130 [deg]F) of each tank.
    5. The liquid portion of the gas at -17.77 [deg]C (0 [deg]F) 
must not completely fill the tank.
    6. The maximum permitted filling density is 125 percent. The 
quantity of chlorine loaded into a single unit-tank car may not be 
loaded in excess of the normal lading weights nor in excess of 81.65 
Mg (90 tons).
    7. 89 percent maximum to 80.1 percent minimum at a test pressure 
of 6.2 bar (90 psig).
    8. 59.6 percent maximum to 53.6 percent minimum at a test 
pressure of 7.2 bar (105 psig).
    9. For a liquefied petroleum gas, the liquefied gas must be 
loaded so that the outage is at least one percent of the total 
capacity of the tank at the reference temperature of 46 [deg]C (115 
[deg]F) for a non-insulated tank; 43 [deg]C (110 [deg]F) for a tank 
having a thermal protection system incorporating a metal jacket that 
provides an overall thermal conductance at 15.5 [deg]C (60 [deg]F) 
of no more than 10.22 kilojoules per hour--per square meter--per 
degree Celsius (0.5 Btu per hour/per square foot/per degree F) 
temperature differential; and 41 [deg]C (105 [deg]F) for an 
insulated tank having an insulation system incorporating a metal 
jacket that provides an overall thermal conductance at 15.5 [deg]C 
(60 [deg]F) of no more than 1.5333 kilojoules per hour--per square 
meter--per degree Celsius (0.075 Btu per hour/per square foot/per 
degree F) temperature differential.
    10. For liquefied petroleum gas and anhydrous ammonia, during 
the months of November through March (winter), the following 
reference temperatures may be used: 38 [deg]C (100 [deg]F) for a 
non-insulated tank; 32 [deg]C (90 [deg]F) for a tank having a 
thermal protection system incorporating a metal jacket that provides 
an overall thermal conductance at 15.5 [deg]C (60 [deg]F) of no more 
than 10.22 kilojoules per hour--per square meter--per degree Celsius 
(0.5 Btu per hour/per square foot/per degree F) temperature 
differential; and 29 [deg]C (85 [deg]F) for an insulated tank having 
an insulation system incorporating a metal jacket and insulation 
that provides an overall thermal conductance at 15.5 [deg]C (60 
[deg]F) of no more than 1.5333 kilojoules per hour--per square 
meter--per degree Celsius (0.075 Btu per hour/per square foot/per 
degree F) temperature differential. The winter reference 
temperatures may only be used for a tank car shipped directly to a 
consumer for unloading and not stored in transit. The offeror of the 
tank must inform each customer that the tank car was filled based on 
winter reference temperatures. The tank must be unloaded as soon as 
possible after March in order to retain the specified outage and to 
prevent a release of hazardous material, which might occur due to 
the tank car becoming liquid full at higher temperatures.
    11. For materials poisonous by inhalation, until December 31, 
2027, the single unit tank car tanks authorized are only those cars 
approved by the Tank Car Committee for

[[Page 79783]]

transportation of the specified material and built prior to March 
16, 2009. After December 31, 2027, all single unit tank cars used in 
PIH/TIH service must meet the requirements of Note 12.
