I. Executive Summary

    The Pipeline and Hazardous Materials Safety Administration (PHMSA) 
proposes to amend the Hazardous Materials Regulations (HMR; 49 CFR 
parts 171 to 180) to maintain alignment with international regulations 
and standards by incorporating various amendments, including changes to 
proper shipping names, hazard classes, packing groups, special 
provisions, packaging authorizations, air transport quantity 
limitations, and vessel stowage requirements. This rulemaking project 
is part of our ongoing biennial process to harmonize the HMR with 
international regulations and standards.
    In this NPRM, PHMSA proposes to amend the HMR to maintain alignment 
with various international standards. The following are some of the 
more noteworthy proposals set forth in this NPRM:
     Incorporation by Reference: PHMSA proposes to incorporate 
by reference the newest versions of various international hazardous 
materials (hazmat) standards, including: The 2019-2020 Edition of the 
International Civil Aviation Organization Technical Instructions for 
the Safe Transport of Dangerous Goods by Air (ICAO Technical 
Instructions); Amendment 39-18 to the International Maritime Dangerous 
Goods Code (IMDG Code); the 20th Revised Edition of the United Nations 
Recommendations on the Transport of Dangerous Goods (UN Model 
Regulations); Amendment 1 to the 6th Revised Edition of the UN Manual 
of Tests and Criteria; and the 7th Revised Edition of the Globally 
Harmonized System of Classification and Labelling of Chemicals (GHS). 
Additionally, we propose to update our incorporation by reference of 
the Transport Canada TDG Regulations to include: SOR/2016-95 published 
June 1, 2016; SOR/2017-137 published July 12, 2017; and SOR/2017-253 
published December 13, 2017. Finally, in this NPRM, PHMSA proposes the 
adoption of updated International Organization for Standardization 
(ISO) standards.
     Hazardous Materials Table: PHMSA proposes amendments to 
the Hazardous Materials Table (HMT; Sec.  172.101) consistent with 
recent changes in the Dangerous Goods List of the 20th Revised Edition 
of the UN Model Regulations, the IMDG Code, and the ICAO Technical 
Instructions. Specifically, we propose amendments to the HMT to add, 
revise, or remove certain proper shipping names, hazard

[[Page 60971]]

classes, packing groups, special provisions, packaging authorizations, 
bulk packaging requirements, and passenger and cargo aircraft maximum 
quantity limits.
     Articles containing dangerous goods: PHMSA proposes to add 
a classification system for articles containing hazardous materials 
that do not already have a proper shipping name. This proposal would 
address situations in which hazardous materials or hazardous materials 
residues are present in articles, and authorize a safe method to 
transport articles that may be too large to fit into typical packages. 
Absent these provisions to package and transport these materials 
safely, these articles may be offered for transport under provisions 
that do not adequately account for the physical and chemical properties 
of the substances and may require the issuance of an approval by 
PHMSA's Associate Administrator for Hazardous Materials Safety.
     Lithium Battery Test Summary: PHMSA proposes the inclusion 
of a lithium battery test summary requirement. The HMR require lithium 
battery manufacturers to subject their batteries to appropriate UN 
design tests to ensure they are classified correctly for transport, and 
develop records of successful test completion. The proposed test 
summary would include a standardized set of elements that provide 
traceability and accountability, thereby ensuring that lithium cell and 
battery designs offered for transport meet the appropriate UN tests.
     Baggage Equipped with Lithium Batteries: PHMSA proposes to 
amend the aircraft passenger provisions for carriage of baggage 
equipped with lithium batteries intended to power features such as 
location tracking, battery charging, digital weighing, or motors 
(sometimes referred to as ``smart luggage''). Specifically, baggage 
equipped with a lithium battery or batteries would be required to be 
carried in the cabin of the aircraft unless the battery or batteries 
are removed.
     Segregation of Lithium Batteries from Specific Hazardous 
Materials: PHMSA proposes requirements to segregate lithium cells and 
batteries from certain other hazardous materials, notably flammable 
liquids, when offered for transport or transported on aircraft. PHMSA 
is taking this action to promote consistency with the ICAO Technical 
Instructions and a recommendation (A-16-001) from the National 
Transportation Safety Board (NTSB) stemming from the investigation of 
the July 28, 2011, in-flight fire and crash of Asiana Airlines Flight 
991 incident that resulted in the loss of the aircraft and crew. The 
investigation report cited as a contributing factor the flammable 
materials and lithium ion batteries that were loaded together either in 
the same or adjacent pallets.
     Alternative criteria for classification of corrosive 
materials: PHMSA proposes to include non-testing alternatives for 
classifying corrosive mixtures that uses existing data on their 
chemical properties. Currently the HMR require offerors to classify 
Class 8 corrosive material and assign a packing group based on test 
data. The HMR authorize a skin corrosion test and various in vitro test 
methods that do not involve animal testing. However, data obtained from 
testing is currently the only data acceptable for classification and 
assigning a packing group. These alternatives would afford offerors the 
ability to make a classification and packing group assignment without 
the need to conduct physical tests.
     Provisions for Polymerizing Substances: PHMSA is proposing 
to extend the sunset dates for provisions concerning the transportation 
of polymerizing substances from January 2, 2019 to January 2, 2021. 
This additional time will allow PHMSA to finalize research and analyze 
comments and data concerning the issue submitted to the docket for this 
NPRM. This information will allow us to have a more comprehensive 
understanding of polymerizing substances and further consider the most 
appropriate transport provisions for these materials.
    If adopted in a final rule, the amendments proposed in this NPRM 
will result in minimal burdens on the regulated community. The benefits 
achieved from their adoption include enhanced transportation safety 
resulting from the consistency of domestic and international hazard 
communication and continued access to foreign markets by U.S. 
manufacturers of hazardous materials. PHMSA anticipates that most of 
the amendments in this NPRM will result in cost savings and will ease 
the regulatory compliance burden for shippers engaged in domestic and 
international commerce, including trans-border shipments within North 
America.
    PHMSA solicits comment from the regulated community on these 
amendments and others proposed in this NPRM pertaining to: Need, 
benefits, and costs of international harmonization; impact on safety; 
and any other relevant concerns. In addition, PHMSA solicits comment 
regarding approaches to reducing the costs of this rule while 
maintaining or increasing the benefits. In its preliminary analysis, 
PHMSA concluded that the aggregate benefits of the amendments proposed 
in this NPRM justify their aggregate costs. Nonetheless, PHMSA solicits 
comment on specific changes (i.e., greater flexibility with regard to a 
particular amendment) that might improve the rule.

II. Background

    Federal law and policy strongly favor the harmonization of domestic 
and international standards for hazardous materials transportation. The 
Federal hazardous materials law (49 U.S.C. 5101 et seq.) directs PHMSA 
to participate in relevant international standard-setting bodies and 
requires alignment of the HMR with international transport standards to 
the extent practicable. Although Federal hazmat law permits PHMSA to 
depart from international standards to promote safety or other 
overriding public interest, it otherwise encourages domestic and 
international harmonization (see 49 U.S.C. 5120).
    In a final rule published December 21, 1990 (Docket HM-181; 55 FR 
52402), PHMSA's predecessor--the Research and Special Programs 
Administration (RSPA)--comprehensively revised the HMR for 
international harmonization with the UN Model Regulations. The UN Model 
Regulations constitute a set of recommendations issued by the United 
Nations Sub-Committee of Experts (UNSCOE) on the Transport of Dangerous 
Goods and the United Nations Sub-Committee of Experts on the Globally 
Harmonized System of Classification and Labelling of Chemicals (GHS). 
The UN Model Regulations are amended and updated biennially by the 
UNSCOE and serve as the basis for national, regional, and international 
modal regulations, including the IMDG Code and the ICAO Technical 
Instructions.
    Since publication of the 1990 rule, PHMSA has issued 12 subsequent 
international harmonization rulemakings.\1\ These rulemakings were 
based on biennial updates of the UN Model Regulations, the IMDG Code, 
and the ICAO Technical Instructions.
---------------------------------------------------------------------------

    \1\ HM-215A [59 FR 67390]; HM-215B [62 FR 24690]; HM-215C [64 FR 
10742]; HM-215D [66 FR 33316]; HM-215E [68 FR 44992]; HM-215G [69 FR 
76044]; HM-215I [71 FR 78595]; HM-215J [74 FR 2200]; HM-215K [76 FR 
3308]; HM-215L [78 FR 987]; HM-215M [80 FR 1075]; and HM-215N [82 FR 
15796].
---------------------------------------------------------------------------

    Harmonization becomes increasingly important as the volume of 
hazardous materials transported in international commerce grows. 
Harmonization not only facilitates international trade by minimizing 
the costs and other burdens of complying with multiple or inconsistent 
safety requirements for

[[Page 60972]]

transportation of hazardous materials, but it also enhances safety when 
the international standards provide an appropriate level of protection. 
PHMSA actively participates in the development of international 
standards for the transportation of hazardous materials and promotes 
the adoption of standards consistent with the HMR. When considering 
alignment of the HMR with international standards, PHMSA reviews and 
evaluates each amendment on its own merit, its overall impact on 
transportation safety, and the economic implications associated with 
its adoption. Our goal is to harmonize with international standards 
without diminishing the level of safety currently provided by the HMR 
or imposing undue burdens on the regulated community.
    Based on recent review and evaluation, PHMSA proposes to revise the 
HMR to incorporate changes from the 20th Revised Edition of the UN 
Model Regulations, Amendment 39-18 to the IMDG Code,\2\ and the 2019-
2020 Edition of the ICAO Technical Instructions, all of which become 
effective January 1, 2019.
---------------------------------------------------------------------------

    \2\ Amendment 39-18 to the IMDG Code may be voluntarily applied 
on January 1, 2019; however, the previous amendment remains 
effective through December 31, 2019.
---------------------------------------------------------------------------

    In addition, PHMSA proposes to incorporate by reference the newest 
editions of various international standards. The standards incorporated 
by reference are authorized for use, under specific circumstances, in 
part 171 subpart C of the HMR. This proposed rule is necessary to 
incorporate revisions to the international standards and, if adopted in 
the HMR, will be effective January 1, 2019.
    PHMSA published a final rule under Docket HM-215N [82 FR 15796 
(March 30, 2017)] that, among other things, added four new Division 4.1 
entries for polymerizing substances to the HMT, and added into the HMR 
defining criteria, authorized packagings, and safety requirements 
including, but not limited to, stabilization methods and operational 
controls. In this prior rulemaking, PHMSA indicated that these changes 
would be in effect until January 2, 2019. During the interim time 
period between publication of the final rule and January 2, 2019, PHMSA 
indicated it would review and research the implications of the 
polymerizing substance amendments, and readdress the issue in the next 
international harmonization rulemaking.
    On January 19, 2017, a Broad Agency Announcement (BAA) \3\ was 
issued soliciting white papers from those interested in undertaking 
research into the appropriate temperature controls for polymerizing 
substances across all package sizes and the impact of gas generation 
from a polymerizing reaction. Submissions were received and reviewed by 
a team of experts to verify, in accordance with the terms of the BAA, 
the technical appropriateness of the proposed work, and the past 
performance of the submitter. Recommendations were submitted to the 
PHMSA Research and Development staff on February 14th, 2018. The 
Research and Development staff is undertaking the necessary next steps 
to initiate the research. By way of this rulemaking, PHMSA also 
solicits comments and data from shippers and classifiers of 
polymerizing substances concerning their experiences operating under 
the transport provisions applied to polymerizing substances in the HM-
215N final rule. Specifically, PHMSA seeks information regarding:
---------------------------------------------------------------------------

    \3\ Broad Agency Announcement (BAA) for innovative research and 
development projects, January 19, 2017. https://www.fbo.gov/spg/DOT/PHMSA/PHMSAHQ/DTPH5617PHMSABAA/listing.html.
---------------------------------------------------------------------------

     Whether affected entities have experienced difficulties 
resulting from differing domestic and international requirements for 
polymerizing substances (e.g., differing temperature thresholds before 
temperature control is required in portable tanks and requirements for 
successfully passing Test Series E prior to offering for transport in a 
portable tank or IBC);
     The experiences of the regulated community in utilizing 
Test Series E with polymerizing substances; and
     Whether there are alternative tests that can indicate 
appropriate responses when potentially polymerizing substances are 
heated under confinement.
    As this research project is presently in the pre-award phase 
prescribed in the BAA and will not be completed prior to the expected 
publication date of a final rule for this NPRM, PHMSA is proposing to 
extend the sunset dates for provisions concerning the transportation of 
polymerizing substances from January 2, 2019 to January 2, 2021. This 
additional time should allow PHMSA to complete its ongoing research 
project and analyze all comments and data concerning the issue 
submitted to the docket for this NPRM. This information will increase 
our comprehension of polymerizing substances and further consider the 
most appropriate transport provisions for these materials. This new 
sunset date is proposed in amendments to Sec. Sec.  172.101, 172.102, 
173.21, and 173.124.

III. Incorporation by Reference Discussion Under 1 CFR Part 51

    The UN Model Regulations, Manual of Tests and Criteria, and 
Globally Harmonized System of Classification and Labelling of 
Chemicals, as well as all of the Transport Canada Clear Language 
Amendments, are free and easily accessible to the public on the 
internet, with access provided through the parent organization 
websites. The ICAO Technical Instructions, IMDG Code, and all ISO 
references are available for interested parties to purchase in either 
print or electronic versions through the parent organization websites. 
The price charged for those not freely available helps to cover the 
cost of developing, maintaining, hosting, and accessing these 
standards. The specific standards are discussed in greater detail in 
the following analysis.

IV. Harmonization Proposals in This NPRM

    In addition to various other revisions to the HMR, PHMSA proposes 
the following amendments to harmonize the HMR with the most recent 
revisions to the UN Model Regulations, ICAO Technical Instructions, and 
IMDG Code, as well as several amendments to further align with the 
Transport Canada TDG Regulations:
     Incorporation by Reference: PHMSA proposes to incorporate 
by reference the newest versions of various international hazardous 
materials standards, including the 2019-2020 Edition of the ICAO 
Technical Instructions; Amendment 39-18 to the IMDG Code; the 20th 
Revised Edition of the UN Model Regulations; amendment 1 to the 6th 
Revised Edition of the UN Manual of Tests and Criteria; and the 7th 
Revised Edition of the GHS. Additionally, we propose to update our 
incorporation by reference of the Transport Canada TDG Regulations to 
include SOR/2016-95 published June 1, 2016; SOR/2017-137 published July 
12, 2017; and SOR/2017-253 published December 13, 2017. Finally, in 
this NPRM, PHMSA proposes the adoption of updated ISO standards.
     Hazardous Materials Table: PHMSA proposes amendments to 
the HMT to add, revise, or remove certain proper shipping names, hazard 
classes, packing groups, special provisions, packaging authorizations, 
bulk packaging requirements, vessel stowage and segregation 
requirements, and

[[Page 60973]]

passenger and cargo aircraft maximum quantity limits.
     Articles containing dangerous goods: PHMSA proposes to add 
a classification scheme for articles containing hazardous materials 
that do not already have a proper shipping name. This proposal would 
address situations in which hazardous materials or hazardous materials 
residues are present in articles. This proposal would authorize a safe 
method to transport articles that may be too large to fit into typical 
packages. Absent these provisions to package and transport these 
materials safely, these articles may be offered for transport under 
provisions that do not adequately account for the physical and chemical 
properties of the substances and may require the issuance of an 
approval by PHMSA's Associate Administrator for Hazardous Materials 
Safety.
     Lithium Battery Test Summary: PHMSA proposes the inclusion 
of a lithium battery test summary requirement. The HMR require lithium 
battery manufacturers to subject their batteries to appropriate UN 
design tests to ensure they are classified correctly for transport, and 
develop records of successful test completion. The proposed test 
summary would include a standardized set of elements that provide 
traceability and accountability, thereby ensuring that lithium cell and 
battery designs offered for transport meet the appropriate UN tests.
     Baggage Equipped with Lithium Batteries: PHMSA proposes to 
amend the aircraft passenger provisions for carriage of baggage 
equipped with lithium batteries intended to power features such as 
location tracking, battery charging, digital weighing, or motors 
(sometimes referred to as ``smart luggage''). Specifically, baggage 
equipped with a lithium battery or batteries would be required to be 
carried in the cabin of the aircraft unless the battery or batteries 
are removed.
     Segregation of Lithium Batteries from Specific Hazardous 
Materials: PHMSA proposes requirements to segregate lithium cells and 
batteries from certain other hazardous materials, notably flammable 
liquids, when offered for transport or transported on aircraft. PHMSA 
is taking this action to promote consistency with the ICAO Technical 
Instructions and a recommendation (A-16-001) from the National 
Transportation Safety Board (NTSB) stemming from the investigation of 
the July 28, 2011, in-flight fire and crash of Asiana Airlines Flight 
991 that resulted in the loss of the aircraft and crew. The 
investigation report cited as a contributing factor the flammable 
materials and lithium ion batteries that were loaded together either in 
the same or adjacent pallets.
     Alternative criteria for classification of corrosive 
materials: PHMSA proposes to include non-testing alternatives for 
classifying corrosive mixtures that instead uses existing data on the 
chemical properties. Currently the HMR require offerors to classify 
Class 8 corrosive material and assign a packing group based on test 
data. The HMR authorize a skin corrosion test and various in vitro test 
methods that do not involve animal testing. However, data obtained from 
testing is currently the only data acceptable for classification and 
assigning a packing group. These alternatives would afford offerors the 
ability to make a classification and packing group assignment without 
the need to conduct physical tests.

V. Amendments Not Being Considered for Adoption in This NPRM

    PHMSA's goal in this rulemaking is to harmonize the HMR with 
international requirements. We are not striving to make the HMR 
identical to the international regulations, but rather to remove or 
avoid potential barriers to international transportation.
    PHMSA proposes changes to the HMR based on amendments adopted in 
the 20th Revised Edition of the UN Model Regulations, the 2019-2020 
Edition of the ICAO Technical Instructions, and Amendment 39-18 to the 
IMDG Code. It is not, however, proposing to adopt all of the amendments 
made to the various international standards into the HMR.
    In many cases, amendments to the international recommendations and 
regulations are not adopted into the HMR because the framework or 
structure of the HMR makes adoption unnecessary. In other cases, we 
have addressed, or will address, the amendments in separate rulemaking 
proceedings.
    The following is a list of significant amendments to the 
international standards that PHMSA is not currently proposing:
     Fuel gas containment systems: The 20th Revised Edition to 
the UN Model Regulations added a special provision to allow for the 
transportation of fuel gas containment systems containing certain gases 
transported for disposal, recycling, repair, inspection, maintenance, 
or from where they are manufactured to a vehicle assembly plant. PHMSA 
does not believe the vehicle specification pressure vessels that are 
incorporated and authorized by the UN Model Regulations apply to 
domestic transportation as most fuel gas containment standards 
addressed are more appropriate for European road and rail regulations. 
PHMSA invites comment on this amendment in the UN Model Regulations and 
whether it would benefit industry to include a similar amendment in the 
HMR.
     Severely damaged and defective lithium batteries: The 20th 
Revised Edition of the UN Model Regulations adopted transportation 
provisions for damaged and defective cells and batteries of UN Nos. 
3090, 3091, 3480 and 3481 liable to rapidly disassemble, dangerously 
react, or produce a flame, a dangerous evolution of heat, or a 
dangerous emission of toxic, corrosive, or flammable gases or vapors 
under normal conditions of transport. In this NPRM, PHMSA is not 
proposing to adopt changes to the domestic requirements for the 
treatment of these lithium batteries, as it believes existing packaging 
and hazard communication requirements in Sec.  173.185(f) sufficiently 
address consignments of this nature.
     Road gas elements vehicles: Amendment 39-18 of the IMDG 
Code adopted provisions for road gas elements vehicles. These vehicles 
contain elements (e.g. cylinders, tubes, bundles of cylinders, pressure 
drums, or tanks) intended for the carriage of gases with a capacity of 
more than 450 L permanently fitted to a vehicle and fitted with 
necessary service equipment. PHMSA believes the HMR provisions 
authorizing the transportation of Multi-Element Gas Containers (MEGCs) 
and tube trailers adequately address the transportation of gases in a 
similar manner.
     Competency-based training: PHMSA is seeking public 
comments on a Competency Based Training approach in this NPRM. The 
2017-2018 ICAO Technical Instructions included proposed revisions to 
their training provisions in Attachment 4,\4\ noting that these 
provisions would replace the current Part 1; Chapter 4 in the 2019-2020 
edition. The provisions presented at the ICAO DGP, and included in the 
2017-2018 ICAO Technical Instructions, on utilizing a competency based 
training approach for dangerous goods have yet to be finalized and 
adopted. We welcome discussions on improving the quality of employee 
training and assessment within the scope of the existing training 
regime. The training provisions as they are currently stated in the HMR 
are not prescriptive and permit a wide latitude in implementation. 
Thus, employers can tailor employee training program in a manner that 
best addresses the job functions performed. Through this flexibility 
employers can utilize various training methods, including the

[[Page 60974]]

Competency Based Training approach. To aid the public in developing 
comments, three documents from ICAO DGP and UNSCOE containing 
information pertaining to Competency Based Training have been provided 
in the public docket for this rulemaking.
    Any comments received may be utilized to better inform PHMSA's work 
in various international forums. Below are some thought starters for 
consideration for your comments:
     If you currently follow a Competency Based Training 
approach to meet the requirements in Part 172, Subpart H:
    [cir] Do you have suggestions or lessons learned that you would 
like to share?
    [cir] What information or tools did/do you consider most helpful in 
implementing a Competency Based Training approach?
    [cir] Have you reviewed the ICAO guidance provided in the Docket? 
If so, did you find the guidance helpful?
     If you do not follow a Competency Based Training approach 
to meet the requirements in Part 172, Subpart H:
    [cir] Have you reviewed the ICAO guidance provided in the Docket? 
If so, did you find the guidance helpful?
    [cir] Are you aware of any barriers to implementing a Competency 
Based Training approach?

VI. Section-by-Section Review

    The following is a section-by-section review of the amendments 
proposed in this NPRM:

Part 171

Section 171.7
    Section 171.7 provides a listing of all voluntary consensus 
standards incorporated by reference into the HMR, as directed by the 
``National Technology Transfer and Advancement Act of 1996.'' According 
to the Office of Management and Budget (OMB), Circular A-119, ``Federal 
Participation in the Development and Use of Voluntary Consensus 
Standards and in Conformity Assessment Activities,'' government 
agencies must use voluntary consensus standards wherever practical in 
the development of regulations. Agency adoption of industry standards 
promotes productivity and efficiency in government and industry, 
expands opportunities for international trade, conserves resources, 
improves health and safety, and protects the environment.
    PHMSA actively participates in the development and updating of 
consensus standards through representation on more than 20 consensus 
standard bodies and regularly reviews updated consensus standards to 
consider their merit for inclusion in the HMR. For this rulemaking, 
PHMSA evaluated updated international consensus standards pertaining to 
proper shipping names, hazard classes, packing groups, special 
provisions, packaging authorizations, air transport quantity 
limitations, and vessel stowage requirements. It determined that the 
revised standards provide an enhanced level of safety without imposing 
significant compliance burdens. These standards have well-established 
and documented safety histories, and their adoption will maintain the 
high safety standard currently achieved under the HMR. Therefore, in 
this NPRM, PHMSA proposes to add and revise the following incorporation 
by reference materials:
     Paragraph (s)(2) would be added, to incorporate the 
International Atomic Energy Agency Code of Conduct on the Safety and 
Security of Radioactive Sources. Section 172.800 references the 
incorporation by reference of this document; however, this entry does 
not currently appear in Sec.  171.7. The proposed addition of this 
paragraph would correct this oversight. The incorporation of this 
document in Sec.  172.800 provides a list of Category 1 and 2 
radioactive sources for which offerors or carriers require a security 
plan.
     Paragraph (t)(1), which incorporates the International 
Civil Aviation Organization Technical Instructions for the Safe 
Transport of Dangerous Goods by Air (ICAO Technical Instructions), 
2015-2016 Edition, would be revised to incorporate the 2019-2020 
Edition. These instructions contain the detailed instructions for the 
international transport of hazardous materials by air.
     Paragraph (v)(2), which incorporates the International 
Maritime Organization International Maritime Dangerous Goods Code (IMDG 
Code), Incorporating Amendment 38-16 (English Edition), would be 
revised to incorporate the 39-18 (English Edition), 2018 Edition. This 
code contains the detailed instructions for the international transport 
of hazardous materials by vessel.
     Paragraph (w), which incorporates various International 
Organization for Standardization entries, would be revised to 
incorporate by reference standards for the specification, design, 
construction, testing, and use of gas cylinders:

--ISO 11118(E), Gas cylinders--Non-refillable metallic gas cylinders--
Specification and test methods would be replaced by ISO 11118:2015(E), 
Gas cylinders--Non-refillable metallic gas cylinders--Specification and 
test methods in paragraph (w)(53). The purpose of this standard is to 
provide a specification for the design, manufacture, inspection, and 
testing of non-refillable metallic gas cylinders for worldwide safe 
use, handling, and transport.
--ISO 11120(E), Gas cylinders--Refillable seamless steel tubes of water 
capacity between 150 L and 3000 L--Design, construction and testing, 
First edition, March 1999 would be replaced by ISO 11120:2015(E), Gas 
cylinders--Refillable seamless steel tubes of water capacity between 
150 L and 3,000 L--Design, construction and testing in paragraph 
(w)(62). This standard provides a specification for the design, 
manufacture, inspection and testing of tubes at the time of manufacture 
for worldwide usage.
--ISO/TR 11364:2012(E), Gas cylinders--Compilation of national and 
international valve system/gas cylinder neck threads and their 
identification and marking system would be added in paragraph (w)(77). 
The purpose of this standard is to list all known cylinder/valve 
threads currently used and also threads used in the past and to specify 
a harmonized identification code and marking system for both cylinders 
and valves.
--ISO 11623(E), Transportable gas cylinders--Periodic inspection and 
testing of composite gas cylinders, First edition, March 2002 would be 
replaced by ISO 11623:2015(E), Transportable gas cylinders--Periodic 
inspection and testing of composite gas cylinders in paragraph (w)(66). 
This standard specifies the requirements for periodic inspection and 
testing and to verify the integrity for further service of hoop-wrapped 
and fully-wrapped composite transportable gas cylinders, with aluminum-
alloy, steel or non-metallic liners or of linerless construction (Types 
2, 3, 4, and 5), intended for compressed, liquefied or dissolved gases 
under pressure, of water capacity from .5 L up to 450 L.
--ISO 14246:2014(E), Gas cylinders--Cylinder valves--Manufacturing 
tests and examination would be added in paragraph (w)(69). This 
standard covers the function of a cylinder valve as a closure (defined 
by the UN Model Regulations).
--ISO 16148:2016(E), Gas cylinders--Refillable seamless steel gas 
cylinders and tubes--Acoustic emission examination (AT) and follow-up 
ultrasonic examination (UT) for

[[Page 60975]]

periodic inspection and testing in paragraph (w)(71). This 
International Standard describes two methods of AT, defined as Method A 
and Method B, and a method of follow-up UT. These non-destructive 
examination techniques are an alternative to conventional testing 
procedures for cylinders and tubes.
--ISO 17871:2015(E) Gas cylinders--Quick-release cylinder valves--
Specification and type testing in paragraph would be added to (w)(72). 
This standard covers the function of a quick-release cylinder valve as 
a closure (defined by the UN Model Regulations).
--ISO 21172-1:2015(E), Gas cylinders--Welded steel pressure drums up to 
3,000 litres capacity for the transport of gases--Design and 
construction--Part 1: Capacities up to 1,000 litres would be added in 
paragraph (w)(75). is to provide a specification for the design, 
manufacture, inspection, and approval of welded steel gas pressure 
drums.
--ISO 22434:2006(E), Transportable gas cylinders--Inspection and 
maintenance of cylinder valves would be added in paragraph (w)(76). 
This International Standard specifies the requirements for the 
inspection and maintenance of cylinder valves, including valves with 
integrated pressure regulators.
     Paragraphs (aa)(1)-(4), which updates 4 existing 
Organization for Economic Cooperation and Development (OECD) guidelines 
concerning corrosivity testing (Nos. 404, 430, 431, & 435). The 
references to these standards would be updated to the 2015 versions of 
the standards.
     Paragraph (bb)(1), which incorporates the Transport Canada 
Transportation of Dangerous Goods Regulations, would add subparagraphs 
(xx), (xxi), and (xxii), to include SOR/2016-95 published June 1, 2016; 
SOR/2017-137 published July 12, 2017; and SOR/2017-253 published 
December 13, 2017, respectively. These proposed additions are to 
incorporate changes to the Transport Canada Transportation of Dangerous 
Goods Regulations.
     Paragraph (bb)(2) would be added to incorporate by 
reference Containers for Transport of Dangerous Goods by Rail, a 
Transport Canada standard that was published in 2013. The standard 
applies to the design, manufacture, maintenance and qualification of 
tank cars and ton containers and the selection and use of large 
containers or transport units used in the handling, offering for 
transport, or transporting of dangerous goods by rail.
     Paragraph (dd)(1), which incorporates the United Nations 
Recommendations on the Transport of Dangerous Goods--Model Regulations, 
19th Revised Edition (2015), Volumes I and II, would be revised to 
incorporate the 20th Revised Edition (2017), Volumes I and II. This 
standard presents a basic scheme of provisions that allow uniform 
development of national and international regulations governing the 
various modes of transport.
     Paragraph (dd)(2)(ii) would be added to incorporate the 
United Nations Recommendations on the Transport of Dangerous Goods, 
Manual of Tests and Criteria, 6th Revised Edition, Amendment 1. This 
standard contains criteria, test methods, and procedures to be used for 
the classification of hazardous materials according to the UN Model 
Regulations.
     Paragraph (dd)(3), which incorporates the United Nations 
Recommendations on the Transport of Dangerous Goods, Globally 
Harmonized System of Classification and Labelling of Chemicals Sixth 
revised edition (2015), would be revised to incorporate the United 
Nations Recommendations on the Transport of Dangerous Goods, Globally 
Harmonized System of Classification and Labelling of Chemicals (GHS), 
7th Revised Edition (2017). This standard helps identify the intrinsic 
hazards found in substances and mixtures and to convey hazard 
information about these hazards.
Section 171.8
    Section 171.8 defines terms generally used throughout the HMR that 
have broad or multi-modal applicability. In this NPRM, PHMSA is 
proposing to amend the definition of ``UN pressure receptacle'' to 
include pressure drums. Additionally, PHMSA proposes to add a 
definition for ``UN Pressure drum'' to mean a welded transportable 
pressure receptacle of a water capacity exceeding 150 L and not more 
than 1,000 L (e.g., cylindrical receptacles equipped with rolling 
hoops, spheres on skids). These amendments provide defining terms 
related to pressure drums for which ISO 21172-1:2015(E) Gas cylinders-- 
Welded steel pressure drums up to 3,000 litres capacity for the 
transport of gases--Design and construction--Part 1: Capacities up to 
1,000 litres is proposed for incorporation in Sec.  178.71.
Section 171.12
    Section 171.12 prescribes requirements for the use of the Transport 
Canada TDG Regulations. In a March 30, 2017, final rule [HM-215N; 82 FR 
15795], PHMSA amended the HMR to expand recognition of cylinders and 
pressure receptacles, cargo tank repair facilities, and certificates of 
equivalency in accordance with the TDG Regulations. The goal of these 
amendments is to promote flexibility and permit the use of advanced 
technology for the requalification and use of pressure receptacles; 
doing so will provide for a broader selection of authorized pressure 
receptacles, reduce the need for special permits, and to facilitate 
cross-border transportation of these cylinders. In this NPRM, PHMSA 
proposes to clarify the recognition of certificates of equivalency 
issued by Transport Canada. Transport Canada issues equivalency 
certificates as both a competent authority approval and for an 
alternative means of compliance with TDG Regulations. PHMSA provides 
reciprocity for equivalency certificates that are issued by Transport 
Canada as an alternative to the TDG Regulations; PHMSA does not provide 
recognition to Canada's competent authority approvals. In this NPRM, 
PHMSA is proposing to amend paragraph (a)(1) to clarify the extent of 
reciprocity regarding certificates of equivalency.
    Additionally, PHMSA is proposing to amend paragraph (a)(3)(v) to 
update the standard incorporated by reference to which Canadian rail 
cars must conform. The existing reference to the Canadian General 
Standards Board standard 43.147 is replaced with Containers for 
Transport of Dangerous Goods by Rail (2013).

Part 172

Section 172.101
    Section 172.101 contains the HMT and provides instructions for its 
use. In this NPRM, PHMSA is proposing to revise the instructional text 
that precedes the HMT for paragraph (e) of this section.
    Paragraph (e) of Sec.  172.101 provides instructions for the use of 
column (4) of the HMT. Column (4) lists the identification number 
assigned to each proper shipping name. Most identification numbers are 
preceded by the letters ``UN'' and are associated with proper shipping 
names, which may be used for both domestic and international 
transportation. Some proper shipping names are assigned ``NA'' or 
``North American'' numbers. As it currently stands, the HMR states that 
NA numbers are afforded recognition in both the United States and 
Canada. Furthermore, under Sec.  171.12, the HMR treats transporting 
hazardous materials to Canada in the same way as domestic 
transportation. This is problematic, however, because specific 
dangerous goods are classified

[[Page 60976]]

differently in the two countries. The Transport Canada Transportation 
of Dangerous Goods Regulations limit the use of NA numbers on transport 
documents to materials classified as ``Consumer commodity,'' and do not 
allow for documentation of other NA numbers. Therefore, in this NPRM, 
PHMSA is proposing to revise paragraph (e) to indicate that NA numbers 
are only recognized for use in the United States.
Hazardous Materials Table (HMT)
    In this NPRM, PHMSA is proposing to amend the HMT. Readers should 
review all changes for a complete understanding of the amendments. For 
purposes of the Government Printing Office's typesetting procedures, 
proposed changes to the HMT appear under three sections of the Table, 
``remove,'' ``add,'' and ``revise.'' Certain entries in the HMT, such 
as those with revisions to the proper shipping names, appear as a 
``remove'' and ``add.'' Proposed amendments to the HMT include the 
following:
New HMT Entries
 UN3537 Articles containing flammable gas, n.o.s.
 UN3538 Articles containing non-flammable, non-toxic gas, 
n.o.s.
 UN3539 Articles containing toxic gas, n.o.s.
 UN3540 Articles containing flammable liquid, n.o.s.
 UN3541 Articles containing flammable solid, n.o.s.
 UN3542 Articles containing a substance liable to spontaneous 
combustion, n.o.s.
 UN3543 Articles containing a substance which emits flammable 
gas in contact with water, n.o.s.
 UN3544 Articles containing oxidizing substance, n.o.s.
 UN3545 Articles containing organic peroxide, n.o.s.
 UN3546 Articles containing toxic substance, n.o.s.
 UN3547 Articles containing corrosive substance, n.o.s.
 UN3548 Articles containing miscellaneous dangerous goods, 
n.o.s.

    PHMSA proposes to add a classification scheme for articles 
containing hazardous materials not otherwise specified by name in the 
HMR that contain hazardous materials of various hazard classes and 
divisions. This proposal addresses transportation scenarios where 
various hazardous materials or hazardous materials residues are present 
in articles above the quantities currently authorized for dangerous 
goods in machinery or apparatus. This proposal authorizes safe and 
secure methods to transport articles that may be too large to fit into 
typical packagings. Absent provisions to package and transport these 
materials safely, such articles may be offered for transport under 
provisions that do not adequately account for the physical and chemical 
properties of the substances or mode of transport and may require the 
issuance of an approval by the Associate Administrator for Hazardous 
Materials Safety.

 UN3535 Toxic solid, flammable, inorganic, n.o.s.

    Consistent with the 20th Revised Edition of the UN Model 
Regulations, this new generic entry addresses toxic solids with a 
flammable subsidiary risk in Packing Groups I and II.

 UN3536 Lithium batteries installed in cargo transport unit 
lithium ion batteries or lithium metal batteries

    This new HMT entry addresses lithium metal and lithium ion 
batteries installed in a cargo transport unit and designed only to 
provide power external to the cargo transport unit. The lithium 
batteries must meet the requirements of Sec.  173.185 and contain the 
necessary systems to prevent overcharge and over discharge between the 
batteries. Such units are forbidden for transport on aircraft.
Amendments to Column (2) Hazardous Materials Descriptions and Proper 
Shipping Names
    Section 172.101(c) describes column (2) of the HMT and the 
requirements for hazardous materials descriptions and proper shipping 
names. For the entry ``2-Dimethylaminoethyl acrylate,'' the word 
``stabilized'' is added to the end, as the substance has been 
determined to polymerize in certain conditions.
Amendments to Column (5) Packing Group
    The HMT entries for articles ``UN3316, Chemical kit'' and ``UN3316, 
First aid kit'' are revised to remove packing group II and III 
assignments. This revision would revert the entries to a single row 
with the packing group column left blank as they existed prior to 
adding the packing group II and III assignments in a final rule 
published on January 8, 2015 [Docket No. PHMSA-2013-0260 (HM-215M); 80 
FR 1075]. This revision would address situations where materials in the 
kits are not assigned to a packing group or have packing group I 
assigned, as permitted by Sec.  173.161.
Amendments to Column (7) Special Provisions
    Section 172.101(h) describes column (7) of the HMT, which contains 
special provisions for each entry in the table. Section 172.102(c) 
prescribes the special provisions assigned to specific entries in the 
HMT. The particular modifications to the entries in the HMT are 
discussed below. See ``Section 172.102 special provisions'' below for a 
detailed discussion of the proposed additions, revisions, and deletions 
to the special provisions addressed in this NPRM.
     Special provision 325. PHMSA proposes to add special 
provision 325 to the following HMT entries:

UN2912 Radioactive material, low specific activity (LSA-I) non fissile 
or fissile-excepted

solutions, varnish, polish, liquid filler and liquid lacquer base
UN1210 Printing ink, flammable or Printing ink related material 
(including printing ink thinning or reducing compound), flammable
UN1866 Resin Solution, flammable

     Special provision 387. PHMSA proposes revising special 
provision 387 to extend the sunset dates for provisions concerning the 
transportation of polymerizing substances from January 2, 2019, to 
January 2, 2021.
     Special provision 388. PHMSA proposes to add new special 
provision 388 to the following HMT entries:

UN3546 Articles containing toxic substance, n.o.s.
UN3547 Articles containing corrosive substance, n.o.s.
UN3548 Articles containing miscellaneous dangerous goods, n.o.s.

     Special provision 421. PHMSA proposes revising special 
provision 421 to extend the sunset dates for provisions concerning the 
transportation of polymerizing substances from January 2, 2019 to 
January 2, 2021.
     Special provision A56. Special provision A56 is revised 
for clarity.
     Special provision A105. PHMSA proposes to revise special 
provision A105 assigned to the following HMT entry:

UN3363 Dangerous goods in machinery or Dangerous goods in apparatus

     Special provision B136. PHMSA proposes to add new special 
provision B136 to the following HMT entries:

Amendments to Column (10) Vessel Stowage Requirements
    Section 172.101(k) explains the purpose of column (10) of the HMT 
and prescribes the vessel stowage and segregation requirements for 
specific entries. Column (10) is divided into two columns: Column (10A) 
[Vessel stowage] specifies the authorized stowage locations on board 
cargo and passenger vessels, and column (10B) [Other provisions] 
specifies special stowage and segregation provisions. The meaning of 
each code in column (10B) is set forth in Sec.  176.84.
    Recent revisions to the stowage categories for Class 1 goods 
greatly simplified the stowage categories, but increased the difficulty 
in shipping explosives as break bulk cargo. Some shippers have found it 
difficult to meet the new stowage categories, particularly stowage 
category 04, which requires shipment on deck in a closed cargo 
transport unit or under deck in a closed cargo transport unit. Many of 
the items contained in these shipments are large and robust articles 
and are difficult to pack in a closed cargo transport unit. This has 
resulted in unnecessary delays and added expense.
    The following table addresses this issue through modification of 
the stowage categories for individual UN numbers for which under deck 
stowage

[[Page 60978]]

was previously permitted prior to Amendment 36-12 of the IMDG Code. 
Table 2 contains the proposed changes listed in numerical order by UN 
identification number and additionally lists the proper shipping name, 
the current column (10A) entry, and the proposed column (10A) entry.

    Consistent with changes to Amendment 39-18 of the IMDG Code, PHMSA 
proposes numerous changes to the special stowage and segregation 
provisions [Other provisions] indicated in column (10B) of the HMT.
    Amendment 39-18 of the IMDG Code amended multiple entries to ensure 
proper segregation between acids and both amines and cyanides. Amines 
react dangerously with acids, evolving heat, and the heat of reaction 
has the potential to generate corrosive vapors. Cyanides react with 
acids to generate toxic vapors. However, current vessel segregation 
requirements are inconsistent. Therefore, PHMSA proposes to apply 
stowage codes 52, 53, and 58--which require stowage ``separated from 
acids,'' ``separated from alkaline compounds'', and ``separated from 
cyanides,'' respectively--to column 10B of the HMT, as shown in Table 
3, below.
    Consistent with changes adopted in Amendment 39-18 of the IMDG 
Code, PHMSA proposes to add existing stowage codes 12 and 25 to entries 
in the HMT. Vessel stowage code 12 requires keeping the cargo as cool 
as reasonably practicable. Vessel stowage code 25 requires protecting 
shipments from sources of heat. PHMSA proposes to add codes 12 and 25 
to Nitrocellulose with alcohol with not less than 25 percent alcohol by 
mass, and with not more than 12.6 percent nitrogen, by dry mass, UN 
2556. The addition of these two vessel stowage codes will help ensure 
that nitrocellulose is stowed so as to keep it as cool as practicable 
during transportation and to avoid possible loss of stabilization 
material in packages. Additionally, PHMSA proposes to add stowage code 
25 to Dipropylamine, UN 2383 consistent with changes adopted in 
Amendment 39-18 of the IMDG Code.
    PHMSA proposes to add vessel stowage codes to multiple HMT entries 
for uranium hexafluoride. In a previous final rule [Docket No. PHMSA-
2015-0273 (HM-215N); 82 FR 15796] a subsidiary hazard of 6.1 was added 
to the UN 2977 and UN 2978 Uranium hexafluoride entries, and the 
primary hazard for UN 3507, Uranium hexafluoride, radioactive material, 
excepted package was changed from 8 to 6.1. Consequential amendments to 
the stowage and segregation requirements codes for these materials were 
not addressed at the time of these changes in the IMDG Code or the HMR. 
In this NPRM, PHMSA is proposing to add existing vessel stowage code 74 
and new vessel stowage code 151 to UN 2977 and UN 2978. Additionally, 
PHMSA proposes to add new vessel stowage code 152 to UN 3507. Stowage 
code 74 requires stowage separated from oxidizers. See section by 
section discussion on proposed changes to Sec.  176.84 for a 
description of stowage code 151 and 152. These proposed amendments are 
necessary to ensure appropriate stowage and segregation provisions that 
account for the subsidiary and tertiary hazards of these commodities.
    Finally, we propose to add new stowage provision 154 and assign it 
to the NA 0123, NA 0494, UN 0494, and UN 0124 jet perforating gun HMT 
entries. This proposed new stowage provision indicates that 
notwithstanding the stowage category assigned to the entries in the 
HMT, jet perforating guns may be stowed in accordance with the 
provisions of packing instruction US 1 in Sec.  173.62. See the 
discussion on stowage provision 154 in the Sec.  176.84 section by 
section portion of this rulemaking.

Appendix B to Sec.  172.101
    Appendix B to Sec.  172.101 lists marine pollutants regulated under 
the HMR. Based on test data submitted to PHMSA, the USCG, and the IMO, 
Amendment 39-18 of the IMDG Code was updated to indicate that 1-
dodecene is not a marine pollutant. In this NPRM, PHMSA is proposing to 
amend the entry for ``Dodecene'' in the list of marine pollutants in 
appendix B to Sec.  172.101 to indicate that 1-dodecene is not a marine 
pollutant, and as a result, shipments of 1-dodecene are not subject to 
the provisions of the HMR applicable to marine pollutants.
Section 172.102 Special Provisions
    Section 172.102 lists special provisions applicable to the 
transportation of specific hazardous materials. Special provisions 
contain

[[Page 60984]]

packaging requirements, prohibitions, and exceptions applicable to 
particular quantities or forms of hazardous materials. In this NPRM, 
PHMSA proposes the following revisions to Sec.  172.102 special 
provisions:
     Special provision 132. This special provision prescribes 
conditions for use of description ``UN 2071, Ammonium nitrate based 
fertilizer, Class 9.'' As the composition limits and requirement on 
self-sustaining decomposition were replaced by a flow chart in sub-
section 39.5 of the new Manual of Tests and Criteria, part III, section 
39, the corresponding UN Model Regulations special provision 193 was 
revised by removing the specific conditions and making a reference to 
the applicable section of the UN Manual of Tests and Criteria. 
Consistent with these changes to the UN Model Regulations, in this 
NPRM, PHMSA is proposing to revise special provision 132 by removing 
the specific conditions applicable to use of this description and 
clarifying that UN 2071 may only be used for ammonium nitrate-based 
compound fertilizers and that they must be classified in accordance 
with the procedure as set out in the Manual of Tests and Criteria, part 
III, section 39.
     Special provision 150. This special provision prescribes 
conditions for use of description ``UN 2067, Ammonium nitrate based 
fertilizer, Division 5.1.'' As the composition limits were replaced by 
a flow chart in sub-section 39.5 of the new Manual of Tests and 
Criteria, part III, section 39, the corresponding UN Model Regulations 
special provision 307 was revised by removing the specific conditions 
and making a reference to the applicable section of the UN Manual of 
Tests and Criteria. Consistent with these changes to the UN Model 
Regulations, in this NPRM, PHMSA is proposing to revise special 
provision 150 by removing the specific conditions applicable to use of 
this description by clarifying that UN 2067 may only be used for 
ammonium nitrate-based fertilizers and that they must be classified in 
accordance with the procedure as set out in the Manual of Tests and 
Criteria, part III, section 39.
     Special provision 238. Special provision 238 prescribes 
requirements for neutron radiation detectors containing boron 
trifluoride. In a final rule published under Docket Number PHMSA 2015-
0273 (HM-215N) [82 FR 15795], special provision 238 was revised to 
align with special provision 373 of the UN Model Regulations. In 
reformatting the special provision for alignment, several of the 
preexisting references to paragraphs within the special provision were 
not revised accordingly. Specifically, in this NPRM, PHMSA is proposing 
to remove the first instance of the text ``a.'' in the introductory 
text as it is not necessary and inadvertently results in two paragraphs 
with the same letter header. In paragraph e, the references to 
preceding paragraphs within the special provision are revised from 
a(1), a(2), and a(3) to a, b, and c, respectively.
     Special provision 325. Consistent with a pre-existing 
Special provision 325 in the UN Model Regulations, PHMSA proposes to 
add new special provision 325 to assist shippers of this material by 
clarifying that in the case of non-fissile or fissile-excepted uranium 
hexafluoride, the material must be classified as ``UN2978 Radioactive 
material, uranium hexafluoride non fissile or fissile-excepted.''. In 
this NPRM, PHMSA proposes to assign Special provision 325 to the 
following entries to aid shippers:

UN2912 Radioactive material, low specific activity (LSA-I) non fissile 
or fissile-excepted
UN2913 Radioactive material, surface contaminated objects (SCO-I or 
SCO-II), non-fissile or fissile excepted
UN2915 Radioactive material, Type A package non-special form, non 
fissile or fissile-excepted
UN2916 Radioactive material, Type B(U) package non fissile or fissile-
excepted
UN2917 Radioactive material, Type B(M) package non fissile or fissile-
excepted
UN2919 Radioactive material, transported under special arrangement, non 
fissile or fissile excepted
UN3321 Radioactive material, low specific activity (LSA-II) non fissile 
or fissile-excepted
UN3322 Radioactive material, low specific activity (LSA-III) non 
fissile or fissile excepted

     Special provision 347. Special provision 347 restricts the 
use of certain HMT entries classed as Division 1.4S explosive materials 
to those articles successfully passing Test series 6(d) of Part I of 
the UN Manual of Tests and Criteria. A Division 1.4 explosive is 
defined as an explosive that presents a minor explosion hazard such 
that hazardous effects are confined to a package and no projection of 
fragments of appreciable size or range are expected; and that an 
external fire must not cause virtually instantaneous explosion of 
almost the entire contents of a package containing a Division 1.4 
explosive. Explosive articles or substances are assigned to Division 
1.4, Compatibility Group S (1.4S) if hazardous effects are confined 
within a package or the blast and projection effects do not 
significantly hinder emergency response efforts.
    Special provision 347 is presently assigned to eight (8) Division 
1.4S entries in the HMT including shaped charges, detonators, power 
device cartridges, detonator assemblies, and plastic bonded bursting 
charges. Following a review of other Division 1.4S entries, the UN 
Working Group on Explosives supported applying Special provision 347 to 
entries for articles and substances whose classification as 1.4S that 
are generic ``not otherwise specified'' (n.o.s.) and to UN 0367 (Fuzes, 
detonating) that are normally package dependent, noting that generic 
entries normally warrant more systematic testing. Therefore, in this 
NPRM, consistent with the UN Model Regulations, PHMSA proposes to add 
special provision 347 to the following entries:
UN0349 Articles, explosives, n.o.s.
UN0367 Fuzes, detonating
UN0384 Components, explosive train, n.o.s.
UN0481 Substances, explosive, n.o.s.

    PHMSA requests comments on whether this proposed provision--to add 
special provision 347 to the four entries--is likely to have net 
benefits.
     Special provision 368. Special provision 368 prescribes 
requirements for non-fissile or fissile-excepted uranium hexafluoride 
that must be described as UN3507 or UN2978, as appropriate. Based on an 
informal working paper submitted at the 50th session of the UN SCOE on 
the Transport of Dangerous Goods that highlighted potential errors in 
the 19th revised edition of the Model Regulations, it was agreed that 
Special provision 368 should have been assigned to ``UN 2908, 
Radioactive material, excepted package--empty packaging'' because empty 
uncleaned packagings containing residues of non-fissile or fissile-
excepted uranium hexafluoride should be classified under UN3507 or 
UN2978 as appropriate. Therefore, in this NPRM, PHMSA proposes to 
assign special provision 368 to the following entry to aid shippers: 
UN2908 Radioactive material, excepted package--empty packaging.
     Special provision 369. Special provision 369 prescribes 
requirements for UN3507, Uranium hexafluoride, radioactive material, 
excepted package, less than 0.1 kg per package, non-fissile or fissile-
excepted. In this NPRM, PHMSA proposes to revise the first sentence of 
the special provision for

[[Page 60985]]

editorial clarity by replacing the words ``a radioactive material and 
corrosive subsidiary risk'' with ``radioactivity and corrosive 
subsidiary risks.''
     Special provision 383. PHMSA proposes to remove special 
provision 383 which allows certain high viscosity flammable liquids, 
when offered for transportation by motor vehicle, to be reassigned to 
Packing Group III when packaged in UN metal drums with a capacity not 
exceeding 220 L (58 gallons). Proposed amendments to Sec.  173.121 in 
this NPRM, if adopted, would provide a larger capacity package, 
additional packaging options, and more modes of transport (all modes 
except air). PHMSA believes these amendments to Sec.  173.121 provide 
more regulatory relief than the existing provisions of special 
provision 383, and thus are proposing the deletion of special provision 
383 and the removal of the special provision from the HMT for those 
entries to which it is assigned.
     Special provision 388. Consistent with the UN Model 
Regulations, PHMSA proposes to add new special provision 388, which 
prescribes requirements for lithium batteries containing both primary 
lithium metal cells and rechargeable lithium ion cells that are not 
designed to be externally charged and for which the existing provisions 
for lithium batteries do not adequately address. Such batteries must 
meet the following conditions: (1) The rechargeable lithium ion cells 
can only be charged from the primary lithium metal cells; (2) 
Overcharge of the rechargeable lithium ion cells is precluded by 
design; (3) The battery has been tested as a primary lithium battery; 
and (4) Component cells of the battery must be of a type proved to meet 
the respective testing requirements of the UN Manual of Tests and 
Criteria, part III, subsection 38.3. Lithium batteries conforming to 
special provision 388 must be assigned to UN Nos. 3090 or 3091, as 
appropriate. When such batteries are transported in accordance with 
Sec.  173.185(c), the total lithium content of all lithium metal cells 
contained in the battery must not exceed 1.5 g and the total capacity 
of all lithium ion cells contained in the battery must not exceed 10 
Wh.
     Special provision 389. In conjunction with the new HMT 
entry ``UN3536, Lithium batteries installed in cargo transport unit 
lithium ion batteries or lithium metal batteries,'' PHMSA proposes to 
add new special provision 389, which prescribes requirements for 
lithium ion batteries or lithium metal batteries installed in a cargo 
transport unit and designed only to provide power external to the cargo 
transport unit. As explained in working paper submitted at the 48\h\ 
session of the UN SCOE on the Transport of Dangerous Goods: ``These 
units generally consist of banks of lithium ion or lithium metal 
batteries, electrically connected and with the necessary battery 
management systems, which are secured to racks, cabinets, or similar 
structures which, in turn, are securely attached to the interior 
structure of closed cargo transport units (typically either freight 
containers or freight vehicles). Thus, in effect, the closed cargo 
transport unit is the casing for a very large lithium battery. These 
battery systems are used in a variety of electric grid and similar 
applications, such as storage of energy generated by farms of large 
wind turbines, and also as a source for emergency power''.
    This proposed special provision which captures many of the safety 
elements included in previous approvals issued by PHMSA would specify 
that the lithium batteries must meet the requirements of Sec.  
173.185(a) and contain the necessary systems to prevent overcharge and 
over discharge between the batteries. The batteries inside the cargo 
transport unit are not subject to marking or labelling requirements of 
part 172 subparts D and E of this subchapter. The cargo transport unit 
shall display the UN number in a manner in accordance with Sec.  
172.332 of this subchapter and be placarded on two opposing sides.
    The batteries must be securely attached to the interior structure 
of the cargo transport unit (e.g., by means of placement in racks, 
cabinets, etc.) in such a manner as to prevent short circuits, 
accidental operation, and significant movement relative to the cargo 
transport unit under the shocks, loadings, and vibrations normally 
incidental to transport. Further, hazardous materials necessary for the 
safe and proper operation of the cargo transport unit (e.g., fire 
extinguishing systems and air conditioning systems), must be properly 
secured to or installed in the cargo transport unit and are not 
otherwise subject to this subchapter. Lastly, hazardous materials not 
necessary for the safe and proper operation of the cargo transport unit 
must not be transported within the cargo transport unit.
     Special provision 391. As part of the classification and 
packaging framework for ``Articles containing dangerous goods'' 
proposed in this rulemaking, PHMSA proposes to add new special 
provision 391, which prohibits articles containing certain high-hazard 
materials of Division 2.3, Division 4.2, Division 4.3, Division 5.1, 
Division 5.2, or Division 6.1 (substances with a inhalation toxicity of 
Packing Group I) and articles containing more than one of the following 
hazards from being offered for transport or transported, except under 
conditions approved by the Associate Administrator for Hazardous 
Materials Safety: (1) Gases of Class 2; (2) Liquid desensitized 
explosives of Class 3; or (3) Self-reactive substances and solid 
desensitized explosives of Division 4.1.
     Special provision 422. PHMSA proposes revising special 
provision 422 to remove the transition period authorizing lithium 
battery Class 9 labels conforming to requirements in place on December 
31, 2016 to continue to be used until December 31, 2018.
     Special provision A56. Special provision A56 prescribes 
requirements for radioactive materials with subsidiary hazards when 
transported by aircraft. In this NPRM, PHMSA proposes to revise special 
provision A56 consistent with the revisions made to special provision 
A78 in the 2019-2020 ICAO Technical Instructions. Specifically, the 
revisions provide guidance for when the subsidiary risk of a 
radioactive material is explicitly forbidden for transport on either a 
passenger or cargo-only aircraft.
     Special provision A105. PHMSA proposes to revise special 
provision A105, which prescribes requirements for the air transport of 
machinery or apparatus containing hazardous materials as an integral 
element of the machinery or apparatus. Where the quantity of hazardous 
materials contained as an integral element in machinery or apparatus 
exceeds the limits permitted for air transport in Sec.  173.222, and 
the hazardous materials meet the provisions of Sec.  173.222 for other 
than air transport, the machinery or apparatus may be transported by 
aircraft only with the prior approval of the Associate Administrator 
for Hazardous Materials Safety.
     Special provision B136. Consistent with the 20th Revised 
Edition of the UN Model Regulations, PHMSA proposes to add new special 
provision B136 that authorizes non-specification closed bulk bins for 
the following solid substances:

UN1363 Copra
UN1386 Seed cake, containing vegetable oil solvent extractions and 
expelled seeds, with not more than 10 percent of oil and when the 
amount of moisture is higher than 11 percent, with not more than 20 
percent of oil and moisture combined
UN1398 Aluminum silicon powder, uncoated
UN1435 Zinc ashes

[[Page 60986]]

UN2071 Ammonium nitrate based fertilizer
UN2216 Fish meal, stabilized or Fish scrap, stabilized
UN2217 Seed cake with not more than 1.5 percent oil and not more than 
11 percent moisture
UN2793 Ferrous metal borings or Ferrous metal shavings or Ferrous metal 
turnings or Ferrous metal cuttings in a form liable to self-heating

     Portable tank special provisions
    PHMSA proposes to revise Portable Tank Special Provision TP10 to 
authorize a three-month extension for the transportation of bromine 
portable tanks for the purposes of performing the next required test--
after emptying, but before cleaning.
     Special provisions W31 and W32. Special provision W32 
currently requires non-bulk packagings to be hermetically sealed, 
except for solid fused material. Amendment 39-18 of the IMDG Code 
removed the qualifying text from the equivalent special packaging 
provision. Discussions at the International Maritime Organization noted 
that when a substance evolves in contact with water flammable gases at 
the rate and quantity meeting the classification requirements for a 
Division 4.3 material, that there is no safety justification to permit 
their transportation in packagings which are not hermetically sealed. 
In Amendment 39-18, the text ``except for solid fused material'' was 
removed from special packing provision PP31 in packing instruction 
P403. PHMSA agrees, and in this NPRM we are proposing deleting special 
provision W32 and assigning W31, which requires non-bulk packagings to 
be hermetically sealed regardless of the form of the material.
     Special provision W40. Special provision W40 prohibits the 
use of non-bulk bags. This requirement typically applies to solid 
substances in Packing Group II. Consistent with changes made in 
Amendment 39-18 of the IMDG Code, PHMSA is proposing that Special 
provision W40 be removed from the following HMT entries:

UN1396/(PG III) Aluminum powder, uncoated
UN1398 Aluminum silicon powder, uncoated
UN1403 Calcium cyanamide with more than 0.1 percent of calcium carbide
UN1405/(PG III) Calcium silicide
U3208/(PG III) Metallic substance, water-reactive, n.o.s.

    Additionally, PPHMSA is proposing to add special provision W40 to 
the following HMT entries:

UN1405/(PG II) Calcium silicide
UN3208/(PG II) Metallic substance, water-reactive, n.o.s.
Section 172.203
    Section 172.203 prescribes additional description requirements for 
shipping papers. In this NPRM, PHMSA proposes to require, in revised 
Sec.  172.203(o), that the words ``TEMPERATURE CONTROLLED'' be added to 
the proper shipping name if not already indicated in the HMT, when 
appropriate. This proposed amendment would provide notice to those in 
the transport chain that a material is being offered under temperature 
control. Additionally, PHMSA proposes to add polymerizing substances to 
the list of types of materials paragraph (o) additional documentation 
requirements apply to.
Section 172.407
    Section 172.407 prescribes specifications for hazard communication 
labels. Consistent with changes made in Amendment 39-18 of the IMDG 
Code and the 2019-2020 ICAO Technical Instructions, PHMSA is proposing 
to amend paragraph (c)(1) to remove the requirement that the width of 
the solid line forming the inner border of labels must be at least 2 
mm. Additionally, we are proposing to amend the requirement that the 
solid line inner border, currently required to be 5 mm inside and 
parallel to the edge, to include the word ``approximately'' before 5 
mm. These changes provide flexibility for minor labeling variations 
that do not have an appreciable impact on transportation safety. 
Finally, paragraph (c)(1)(iii) which contains a transitional exception 
allowing for labels in conformance with the requirements of 49 CFR 
172.407(c)(1) (revised as of October 1, 2014) to continue to be used 
until December 31, 2018, is removed and reserved.
Section 172.514
    Section 172.514 prescribes placarding requirements and exceptions 
for a bulk packaging containing a hazardous material. The general 
placarding requirements prescribe that bulk packagings are to be 
placarded on each side and each end. Due to the form and shape (e.g., 
round) of flexible bulk containers it is impractical to require 
placards on each side and each end. Consistent with the IMDG Code, in 
this NPRM, PHMSA is proposing to allow flexible bulk containers to be 
placarded in two opposing positions.
Section 172.604
    Section 172.604 prescribes requirements for emergency response 
telephone numbers. Paragraph (d) identifies materials for which an 
emergency response telephone number is not required when offered for 
transportation. In a March 30, 2017 final rule [HM-215N; 82 FR 15795], 
PHMSA harmonized the HMR with international regulations by adopting 
separate HMT entries for internal combustion engines based on the fuel, 
i.e., engine, internal combustion, flammable liquid powered and engine, 
internal combustion, flammable gas powered. Previously, a single HMT 
entry covered all engines. At that time, we did not amend Sec.  
172.604(d)(2) to ensure that ``engines, internal combustion'' offered 
under any of the new proper shipping names would continue to be 
excepted from the emergency response telephone requirements of Sec.  
172.604. In this NPRM, PHMSA proposes amending paragraph (d)(2) to list 
all possible proper shipping names for engines per the original intent.
Section 172.800
    Section 172.800 prescribes the requirements for developing and 
implementing plans to address security risks related to the 
transportation of hazardous materials in commerce. During review of 
existing references that are incorporated by reference in the HMR it 
was noted that the IAEA Code of Conduct Category 1 and 2, while 
referenced in paragraph (b)(15) was not appropriately incorporated by 
reference (see Sec.  171.7). In this NPRM, PHMSA is proposing to 
incorporate by reference the IAEA Code of Conduct on the Safety and 
Security of Radioactive Sources into paragraph (b)(15). Furthermore, we 
are proposing to revise a reference to known radionuclides in forms 
listed as RAM-QC by the Nuclear Regulatory Commission, to Nuclear 
Regulatory Commission, Category 1 and Category 2 radioactive materials 
as listed in Table 1, Appendix A to 10 CFR part 37. Lastly, we are 
listing the reference to Highway Route Controlled Quantities separately 
in this paragraph. This proposed amendment does not require the 
creation and retention of security plans by any new individuals, but 
simply incorporates by reference the appropriate IAEA reference and 
clarifies the existing requirement.

Part 173

Section 173.2a
    Section 173.2a outlines classification requirements for materials 
having more than one hazard. PHMSA is proposing to amend paragraph (a) 
to indicate the appropriate classification precedence for the new 
``Articles'' HMT entries

[[Page 60987]]

proposed in this NPRM. This change will give guidance to offerors and 
shippers using the new HMT entries numbers that do not conform to a 
single hazard class.
Section 173.6
    Section 173.6 provides authorization for certain hazardous 
materials meeting the definition of a material of trade (MOT) to be 
transported by motor vehicle in conformance with this section and be 
excepted from all other requirements of this subchapter if certain 
quantity limitations, packaging provisions, and hazard communication 
requirements are met. In two recent rulemakings [HM-218H; 81 FR 35483] 
and [HM-215N; 82 FR 15795] PHMSA removed packing group assignments from 
Column (5) of the HMT for all organic peroxides (Division 5.2), self-
reactive substances (Division 4.1), explosives (Class 1), and articles 
containing hazardous materials. This removal of an indication of 
packing group for these materials and articles has led to questions on 
the ability of these materials and articles to utilize the MOTs 
exceptions provided in Sec.  173.6. Further, in this NPRM the addition 
of twelve new proper shipping names for articles is proposed. These 
proposed new proper shipping names are also not assigned a packing 
group. See ``Section 172.101 Hazardous Materials Table (HMT)'' for a 
detailed discussion of this proposal.
    It was not the intention of these previous rulemakings or this NPRM 
to exclude these materials and articles from the ability to utilize the 
MOTs exceptions, provided the hazardous materials within the articles 
comply with the existing quantity limitations and other transport 
provisions of Sec.  173.6. In this NPRM, PHMSA proposes to add a new 
paragraph (a)(7) to clarify that materials and articles for which 
Column (5) of the Hazardous Materials Table in Sec.  172.101 does not 
indicate a packing group are authorized to utilize the MOTs exceptions 
as applicable, and indicate the appropriate quantity limits applicable 
to those materials in articles. In addition, PHMSA proposes to revise 
paragraph (b)(3) to clarify the securement requirement for the 
transportation of articles under the MOTS exceptions.
    The packaging section 173.232 proposed in this NPRM for the new 
proper shipping names for articles requires packaging at the Packing 
Group II performance level. Non-specification packaging and 
transportation unpackaged is also authorized.
    In addition, the two previous rulemakings removed packing groups 
from all organic peroxides (Division 5.2), self-reactive substances 
(Division 4.1), explosives (Class 1), and the specific articles 
indicated in Table 4 below. All articles and materials for which a 
packing group was recently removed from the HMT, the corresponding 
section referenced in Column (8) of the Sec.  172.101 Table requires 
either packaging meeting Packing Group II or III performance level 
requirements or non-specification packaging is authorized. Thus, PHMSA 
believes clarifying that materials and articles that are not assigned a 
Packing Group in the HMT are eligible to utilize the MOTs exception, 
and indicating that the appropriate quantity limit for these materials 
and articles based on the PG II or PG III levels shown in Sec.  
173.6(a)(1)(ii) or as shown in Sec.  173.6(a)(3) for articles 
containing Division 4.3 materials is appropriate to remove any doubt 
concerning MOTs applicability to these materials and articles.

Section 173.62
    Section 173.62 outlines specific packaging requirements for 
explosives. In paragraph (c), in the Table of Packing Methods, Packing 
Instruction US 1 containing packing instructions for jet perforating 
guns, PHMSA is proposing to increase the maximum authorized amount of 
explosive contents per tool pallet and cargo vessel compartment from 
90.8 kg to 95 kg. These limits are consistent with a provision added to 
Amendment 39-18 of the IMDG Code authorizing jet perforating guns to be 
transported to or from offshore oil platforms, mobile offshore drilling 
units, and other offshore installations in offshore well tool pallets, 
cradles, or baskets. PHMSA notes that the amendments adopted in section 
7.1.4.4.5 of Amendment 39-18 of the IMDG Code require both ends of jet 
perforating guns to be protected by means of steel end caps. PHMSA is 
not proposing to adopt this additional requirement for steel end caps 
noting the safe transportation record of these explosive articles under 
the existing requirements of the HMR.
Section 173.121
    Section 173.121 provides criteria for the assignment of packing 
groups to Class 3 materials. Paragraph (b) provides criteria for 
viscous flammable liquids of Class 3 (e.g., paints, enamels, lacquers, 
and varnishes) to be placed in packing group III on the basis of their 
viscosity, coupled with other criteria. Consistent with recent changes 
to the IMDG Code, PHMSA is proposing to amend paragraph (b)(1)(iii) to 
authorize a packaging capacity up to 450 L (119 gallons), an increase 
from the presently authorized 30 L. A working paper submitted to the 
IMO Sub-Committee on Carriage of Cargoes and Containers (CCC), noted 
that both the UN Model Regulations and The European Agreements 
Concerning the

[[Page 60988]]

International Carriage of Dangerous Goods by Road (ADR) and Rail (RID) 
allow receptacles up to 450 L, and that due to the nature of viscous 
materials (e.g. lower flow rate in the event of damage to a receptacle, 
and lower levels of solvent vapors) which present a lower fire risk 
than non-viscous flammable liquids there has been a history of safe 
transport of these materials by road and rail since the introduction of 
the provision. The working paper also explained that:

    Recognizing that global transport of dangerous goods is 
inherently multi-modal, the harmonization of the IMDG Code with 
other modes will aid trade and reduce incidents of non-compliance 
due to misunderstandings. At the point of packing, the manufacturer 
will not know which route (by road/rail/inland waterway or sea) the 
package will take. This leads to the possibility of accidental 
consignment by sea of packages between 30 and 450 litres.

    This proposed change would increase the allowed volume of viscous 
liquids in a single package and would be applicable to all modes except 
for air. Specifically, in this NPRM, PHMSA is proposing to increase the 
packaging limits for viscous flammable liquids of packing group II 
material that may be placed in packing group III. For transport by 
vessel, PHMSA proposes an increase from 30 L to 450 L. For transport by 
rail and highway, PHMSA proposes an increase from 100 L to 450 L. 
Consistent with the ICAO Technical Instructions, the packaging quantity 
limits to air will remain 30 L for passenger aircraft and 100 L for 
cargo aircraft.
Section 173.124
    Section 173.124 contains definitions for Class 4, Divisions 4.1, 
4.2, and 4.3. In this NPRM, PHMSA is proposing to amend paragraph 
(a)(4)(iv) to extend the sunset dates for provisions concerning the 
transportation of polymerizing substances from January 2, 2019, to 
January 2, 2021. See the background section of this rulemaking for a 
more detailed discussion on polymerizing substances.
Section 173.127
    Section 173.127 provides a definition and criteria for the 
assignment of packing groups for Division 5.1 Oxidizers. A new Section 
39 in the UN Manual of Tests and Criteria was introduced containing all 
provisions for the classification of ammonium nitrate based 
fertilizers. As a consequence of the new section, existing text in both 
the Manual and the Model Regulations was amended or removed to avoid 
duplicative provisions in both publications. In this NPRM, PHMSA is 
proposing to revise the classification criteria for solid ammonium 
nitrate based fertilizers by requiring that they are classified in 
accordance with the procedures prescribed in the UN Manual of Tests and 
Criteria, Part III, Section 39. These proposed changes are not intended 
to result in changes to the current classification provisions for 
ammonium nitrate fertilizers, but rather consolidate the provisions for 
ease of use and prevent inadvertent misclassification.
Section 173.134
    Section 173.134 provides definitions and exceptions for infectious 
substances. Consistent with the UN Model Regulations, PHMSA is 
proposing to revise the definition for ``patient specimen'' in 
paragraph (a)(4) by removing redundant references to humans and 
animals.
Section 173.136
    Section 173.136 provides the definition for corrosive materials. In 
the UN Model Regulations, the definition for corrosive materials was 
revised to align with the current text in Chapter 3.2 of the UN GHS and 
the Organization for Economic Cooperation and Development (OECD) Test 
Guidelines for Testing of Chemicals. PHMSA is proposing to amend the 
definition in paragraph (a) for a corrosive material by replacing the 
text ``full thickness destruction'' with ``irreversible damage.''
Section 173.137 and Appendix I to Part 173
    Section 173.137 prescribes the requirements for assigning a packing 
group to Class 8 materials. Currently the HMR require offerors to 
classify Class 8 corrosive material and assign a packing group based on 
test data. The HMR authorize a skin corrosion test and various in vitro 
test methods that do not involve animal testing. However, data obtained 
from either currently authorized test is generally the only data 
acceptable for classification and assignment of a packing group. In 
this NPRM, consistent with changes to the UN Model Regulations, PHMSA 
proposes to include alternative packing group assignment methods for 
making a corrosivity classification determination for mixtures that do 
not involve testing. These proposed amendments include bridging 
principles and a calculation method for the classification of mixtures.
    In a new paragraph (d), PHMSA proposes creating an alternative, 
tiered approach to classification and packing group assignment 
depending on how much information is available about the mixture 
itself, similar mixtures, and/or the mixture's ingredients. When 
sufficient data is available on similar mixtures to estimate skin 
corrosion hazards for bridging, the bridging principle method may be 
used to classify and assign a packing group. When no bridging data is 
available, the more conservative calculation method may be used. This 
tiered approach ensures an appropriate level of safety in situations 
where reliable data may not be available. These alternatives for 
classifying corrosive mixtures allow offerors the ability to make a 
classification and packing group assignment without having to conduct 
physical tests.
    Additionally, the new corrosivity classification methods are much 
more closely aligned with those found in the UN GHS. However, not all 
GHS corrosivity classification methods were incorporated in the new UN 
Model Regulations corrosivity requirements. For example, the use of 
extreme pH values to assign corrosivity were not addressed in the UN 
Model Regulations, and as such are not proposed in this NPRM. 
Consistent with the proposed change to the definition of a corrosive 
material in Sec.  173.136, PHMSA is proposing to replace all instances 
of the text ``full thickness destruction'' with ``irreversible 
damage.'' PHMSA is also proposing to add a new appendix I to part 173, 
containing a flow chart for use with the calculation method.
    Finally, PHMSA is proposing to update the four existing OECD 
Guidelines currently incorporated by reference in this section to their 
2015 versions (Test Nos. 404, 430, 431, and 435). OECD Guideline 404 
and OECD Guideline 435 contain minor variations in the types of 
information to be recorded as a part of the test report in relation to 
the previously incorporated versions. OECD Guideline 430 and OECD 
Guideline 431 were updated to include a reference to a developed 
document on integrated approaches to testing and assessment. OECD 
Guideline 431.
Section 173.159
    Section 173.159 prescribes requirements applicable to the 
transportation of electric storage batteries containing electrolyte 
acid or alkaline corrosive battery fluid (i.e., wet batteries). 
Consistent with the UN Model Regulations, PHMSA is proposing several 
editorial amendments in paragraphs (a) and (d) to specify that 
electrically non-conductive packaging materials must be used and that 
contact

[[Page 60989]]

with other electrically conductive materials must be prevented.
Section 173.185
    Section 173.185 prescribes requirements for lithium cells and 
batteries. The introductory paragraph defines terms as used in this 
section. In this NPRM, PHMSA is proposing to clarify in the 
introduction that a single cell battery is considered a ``cell'' and 
must be transported in accordance with the requirements for cells. In 
Sec.  173.185(a), the HMR describe UN cell and battery design testing, 
general cell and battery design safety requirements, and packaging 
requirements. In this NPRM, PHMSA proposes to amend Sec.  173.185(a) to 
include a lithium cell and battery test summary with a standardized set 
of elements. Manufacturers and subsequent distributers of lithium cells 
and batteries manufactured after June 30, 2003, must make this 
information available to others in the supply chain. This action is 
intended to provide subsequent distributors and consumers the 
information necessary to ensure that lithium cells and batteries 
offered and reoffered for transport meet the appropriate UN design 
tests. This test summary is intended to provide a signal to users that 
the battery is from a legitimate and compliant source, and allowing 
those in the transport chain to more easily identify non-counterfeit 
products. PHMSA, believes that potential ancillary benefits from this 
proposed lithium battery test summary include; a reduction in shipments 
of counterfeit cells and batteries, incremental safety gains in 
transport and use due to an increase in the use of batteries that are 
of a tested and approved type, and additional benefits received by 
consumers from a higher quality battery (e.g., a higher capacity 
factor, slower decay rate, longer life expectancy, better warranties, 
more reliable customer service).
    PHMSA developed a guidance document to assist manufacturers and 
distributors with understanding and implementing this requirement. The 
guidance includes an explanation of the requirement, a sample test 
summary, and questions and answers. A copy of this guidance is 
available in the docket for this rulemaking. PHMSA requests comments on 
the usefulness of the guidance material and comments to improve its 
clarity and additional questions to add to the guidance.
    The HMR in Sec.  173.185(b) require lithium cells and batteries to 
be packed in inner packagings in such a manner as to prevent short 
circuits, including movement which could lead to short circuits. These 
inner packagings must be placed in an outer package conforming to the 
requirements of part 178, subparts L and M, at the Packing Group II 
performance level. PHMSA proposes several amendments to Sec.  
173.185(b) to update and clarify various provisions. PHMSA proposes to 
amend Sec.  173.185(b)(2)(ii) to specify that lithium cells and 
batteries including lithium cells or batteries packed with, or 
contained in, equipment, must be packaged in a manner that prevents 
damage caused by movement or placement within the package. The current 
text requires lithium batteries to be packaged in a manner to prevent 
movement. This could be interpreted as to require no movement within 
the package. This proposed amendment would minimize ambiguity in the 
current requirements and only prohibit movement that leads to damage 
within the package.
    Further, PHMSA proposes to amend Sec.  173.185(b)(3)(i) to specify 
that inner packagings must be separated from electrically conductive 
materials. This proposed change is based on revisions to the UN Model 
Regulations that revised the existing requirement that inner packagings 
separate lithium cells and batteries from conductive materials to 
require separation from ``electrically conductive'' materials. PHMSA 
proposes to amend Sec.  173.185(b)(6) to clarify the provisions for the 
use of large packagings. Currently, large packagings are authorized for 
the transport of a single battery including a battery contained in 
equipment. This amendment would clarify that large packagings are 
limited to a single battery or to a single item of equipment. This 
acknowledges that a single item of equipment may contain one or more 
batteries. Finally consistent with revisions to the ICAO Technical 
Instructions, PHMSA proposes to add a new paragraph (b)(7) to prohibit 
the placement of lithium batteries in the same outer packaging as 
substances and articles of the following classes and divisions: Class 1 
(explosives) other than Division 1.4S; Division 2.1 (flammable gases); 
Class 3 (flammable liquids); Division 4.1 (flammable solids); or 
Division 5.1 (oxidizers) when offered for transport or transported by 
aircraft. PHMSA is proposing this action to promote consistency with 
the ICAO Technical Instructions and in response to a recommendation (A-
16-001) from the National Transportation Safety Board (NTSB) stemming 
from the investigation of the July 28, 2011, in-flight fire and crash 
of Asiana Airlines Flight 991 that resulted in the loss of the aircraft 
and crew. The investigation report cited as a contributing factor the 
flammable materials and lithium ion batteries that were loaded together 
either in the same or adjacent pallets. Logically, if the materials are 
not allowed to be stowed in the same or adjacent pallets, segregation 
within the same package also would result in decreased risk in the 
event of a fire.
    From our experience with public comments on this issue related to 
ICAO and the UN, PHMSA understands it is not common industry practice 
nor a desired option for U.S. shippers to pack lithium batteries with 
other hazardous materials in the same outer package. There appears to 
be limited U.S. market interest in this type of packing configuration. 
Therefore. PHMSA expects codifying this provision to have negligible 
negative implications to U.S. shippers while leveling the playing field 
by applying the provision to non-US originating shipments imported into 
the U.S.
    Section 173.185(c) of the HMR describes provisions for the carriage 
of up to eight small lithium cells or two small lithium batteries per 
package with alternative hazard communication that replaces the Class 9 
label with a lithium battery mark. Additional conditions for the 
transport of small lithium cells and batteries by air are contained in 
Sec.  173.185(c)(4). In this NPRM, PHMSA proposes several amendments to 
Sec.  173.185(c)(2), (c)(3), and (c)(4) to align the HMR with the UN 
Model Regulations and the ICAO Technical Instructions, address the 
hazards associated with placing lithium batteries next to other 
hazardous materials, and clarify specific provisions. PHMSA proposes to 
amend Sec.  173.185(c)(2) to except equipment that is robust enough to 
protect lithium batteries from damage or short circuit from the 
requirement to be packaged. The current regulations provide an 
exception from the requirement for the package to be rigid, but 
otherwise requires the equipment to be placed into a package. This 
proposed amendment would remove an unnecessary requirement to package 
otherwise robust equipment that protect lithium batteries from damage 
or short circuits. This proposal further aligns the HMR with the UN 
Model Regulations provisions found in special provision 188 for 
packaging of lithium cells batteries and equipment. PHMSA proposes to 
add a new Sec.  173.185(c)(3)(iii) to require that when packages of 
lithium cells or batteries required to bear the lithium battery mark 
are placed in an overpack, the lithium battery mark must either (1) be 
clearly visible through the overpack; or

[[Page 60990]]

(2) the lithium battery mark must also be affixed on the outside of the 
overpack, and the overpack must be marked with the word ``OVERPACK'' in 
lettering at least 12 mm (0.47 inches) high. PHMSA proposes to amend 
Sec.  173.185(c)(4)(ii) to adopt an ``OVERPACK'' marking minimum size 
requirement consistent with the proposed requirement for surface 
transport in Sec.  173.185(c)(3)(iii). PHMSA proposes to clarify the 
limits for spare batteries in Sec.  173.185(c)(4)(iv) to state that up 
to ``two spare sets'' of cells or batteries can be placed in a package 
with equipment. For the purposes of this paragraph, a spare set is 
equal to the number of individual spare cells or batteries required to 
power each piece of equipment. For example, if a single item of 
equipment requires two lithium batteries to operate, a maximum of four 
additional batteries (two spare sets) may be placed in the package 
provided the package continues to meet the other conditions of Sec.  
173.185(c). PHMSA proposes to add a new Sec.  173.185(c)(4)(v) to 
specify that for air transport, lithium cells and batteries may not be 
placed in the same package as other hazardous materials. Further, 
packages containing small lithium cells and batteries must not be 
placed into an overpack with packages containing Class 1 (explosives) 
other than Division 1.4S, Division 2.1 (flammable gases), Class 3 
(flammable liquids), Division 4.1 (flammable solids) or Division 5.1 
(oxidizers). Each of the remaining sub-paragraphs in Sec.  
173.185(c)(4) would be renumbered and remain unchanged. PHMSA is 
proposing this action to promote consistency with the ICAO Technical 
Instructions and in response to a recommendation (A-16-001) from the 
National Transportation Safety Board (NTSB) stemming from the 
investigation of the July 28, 2011, in-flight fire and crash of Asiana 
Airlines Flight 991 that resulted in the loss of the aircraft and crew. 
The investigation report cited as a contributing factor the flammable 
materials and lithium ion batteries that were loaded together either in 
the same or adjacent pallets. Logically, if the materials are not 
allowed to be stowed in the same or adjacent pallets, segregation 
within the same package also would result in decreased risk in the 
event of a fire.
    Section 173.185(d) of the HMR describes provisions for the 
transport of lithium cells and batteries for disposal or recycling. In 
this NPRM, PHMSA proposes to authorize the use of certain rigid large 
packagings to transport a single large battery or a single large item 
of equipment. This will provide additional packaging options to 
transport large batteries and equipment that by nature of their size or 
shape cannot fit into a non-bulk package. The UN Model Regulations do 
not include large packagings as an option for lithium batteries shipped 
for disposal or recycling. Nevertheless, PHMSA expects that large 
batteries and equipment would potentially require large packagings. 
Like the authorizations for the use of large packagings elsewhere in 
Sec.  173.185, PHMSA would authorize the use of a large packaging for a 
single large battery or a single item of equipment containing 
batteries. PHMSA proposes to separate the existing Sec.  173.185(d) 
into separate subparagraphs (d)(1) and (2) to accommodate these 
amendments.
    Section 173.185(e) of the HMR describes provisions for the 
transport of low production and prototype lithium cells and batteries 
including equipment. In this NPRM, PHMSA proposes an editorial 
amendment to the Sec.  173.185(e) introductory paragraph to clarify 
that the ``transported for purposes of testing'' condition applies to 
prototype cells and batteries and that both low production and 
prototype lithium cells and batteries may be contained in equipment. 
PHMSA also proposes an editorial amendment to paragraphs (e)(1) and (2) 
to specify that cushioning material must be electrically non-conductive 
instead of the existing ``non-conductive'' requirement. In addition, 
PHMSA proposes a new paragraph (e)(4) to authorize the use of certain 
rigid large packagings to transport a single large battery or a single 
large item of equipment. This will provide additional packaging options 
to transport large batteries and equipment that by nature of their size 
or shape cannot fit into a non-bulk package. Each of the remaining sub-
paragraphs in Sec.  173.185(e) would be renumbered and remain 
unchanged.
    Section 173.185(f) of the HMR describes provisions for the 
transport of lithium batteries that have been damaged or identified by 
the manufacturer as being defective for safety reasons, and that have 
the potential of producing a dangerous evolution of heat, fire, or 
short circuit (e.g., those being returned to the manufacturer for 
safety reasons). PHMSA proposes an editorial amendment to Sec.  
173.185(f)(2) to specify that cushioning material must be electrically 
non-conductive, which would harmonize the HMR with the international 
standards. PHMSA also proposes to amend Sec.  173.185(f)(3) to clarify 
the provisions for the use of large packagings. Currently, large 
packagings are authorized for the transport of a single battery 
including a battery contained in equipment. This amendment would 
clarify that large packagings are limited to a single battery and to a 
single item of equipment. This acknowledges that a single item of 
equipment may contain one or more batteries.
Section 173.218
    Section 173.218 contains packaging requirements for shipments of 
stabilized fish meal and fish scrap. Stabilization of fish meal and 
fish scrap by applying antioxidants is required in order to offer the 
material under a Class 9 stabilized proper shipping name. Historically, 
the IMDG Code and the HMR only reference one antioxidant--ethoxyquin--
by name although other antioxidants exist. In response to testing 
performed by the International Fishmeal and Fish Oil Organization 
(IFFO) \5\ that indicated that of concentrations of 50 ppm (mg/kg) of 
ethoxyquin, 100 ppm (mg/kg) of butylated hydroxytoluene (BHT), and 250 
ppm (mg/kg) of tocopherol-based antioxidant are effective in 
stabilizing fish meal, the UN and the IMO adopted allowances for the 
use of two additional antioxidants (butylated hydroxytoluene and 
tocopherols) and a reduction in the required ethoxyquin concentration 
at time of shipment from 100 ppm to 50 ppm.
---------------------------------------------------------------------------

    \5\ https://www.unece.org/fileadmin/DAM/trans/doc/2016/dgac10c3/ST-SGAC.10-C.3-2016-82e.pdf.
---------------------------------------------------------------------------

    In this NPRM, PHMSA is proposing to amend paragraph (c) of this 
section to lower the required ethoxyquin level at the time of shipment 
in bulk in freight containers for transportation by vessel from 100 ppm 
to 50 ppm and to specify acceptable levels of for butylated 
hydroxytoluene (100 ppm) and for tocopherols (250 ppm) in shipments of 
fish meal or fish scrap transported by vessel in bulk in freight 
containers. Reducing the required minimum concentration of ethoxyquin 
and permitting the use of additional antioxidants would potentially 
reduce cost, add flexibility while maintaining an equivalent level of 
safety.
Section 173.220
    Section 173.220 prescribes transportation requirements and 
exceptions for internal combustion engines, vehicles, machinery 
containing internal combustion engines, battery-powered equipment or 
machinery, and fuel cell-powered equipment or machinery.
    Special provision 135 is assigned to the HMT entries for certain 
vehicles. It specifies that if a vehicle is powered by

[[Page 60991]]

both a flammable liquid and a flammable gas internal combustion engine, 
it must be consigned under the entry ``Vehicle, flammable gas 
powered.'' Special provision 135 does not, however, clearly indicate 
that a flammable gas powered vehicle must also comply with the 
requirements applicable to the quantity of flammable liquid in the fuel 
tank in addition to all of the applicable provisions for flammable gas-
powered vehicle. Consistent with the ICAO Technical Instructions, PHMSA 
proposes to clarify in a new paragraph (b)(2)(ii)(C) that if a vehicle 
is powered by a flammable liquid and a flammable gas internal 
combustion engine, the flammable liquid fuel tank requirements of 
paragraphs (b)(1) of this section must also be met.
    In this NPRM, PHMSA is proposing to make an editorial amendment to 
the requirements for vehicles powered by lithium batteries in paragraph 
(d). Specifically, we are clarifying that when a lithium battery is 
removed from the vehicle and is packed separately from the vehicle in 
the same outer packaging, the package must be classified as ``UN 3481, 
Lithium ion batteries packed with equipment'' or ``UN 3091, Lithium 
batteries packed with equipment,'' and is not eligible for 
classification as ``UN3171, Battery-powered vehicle or Battery-powered 
equipment.'' This clarification is a result of a working paper 
submitted at the 26th Meeting of the ICAO Dangerous Goods Panel (ICAO 
DGP/26) concerning the carriage of battery powered vehicles such as 
``e-bikes'' and it addresses instances where a shipper removes the 
lithium battery from the battery powered vehicle and subsequently packs 
the battery in a separate packaging which is then placed with the 
vehicle in the same outer packaging. Although this was the result of an 
amendment to the ICAO Technical Instructions, we believe that it 
provides clarification of a preexisting requirement for all modes of 
transport.
Section 173.222
    Section 173.222 specifies the requirements for dangerous goods in 
machinery or apparatus. During the course of reviewing provisions 
associated with the new HMT entries for ``Articles containing hazardous 
materials, n.o.s.,'' PHMSA found that the quantity limits prescribed in 
Sec.  173.222 are inconsistent with certain international standards. 
The current authorized quantity of hazardous materials in one item of 
machinery or apparatus are as follows: 1 kg for solids; 0.5 L for 
liquids, and 0.5 kg for Division 2.2 gases. These quantity limits are 
consistent with the ICAO Technical Instructions; however, they are not 
aligned with the UN Model Regulations or the IMDG Code. Special 
provision 301 of the UN Model Regulations and the IMDG Code authorize 
up to the limited quantity amount for each item of dangerous goods 
contained in the machinery or apparatus.
    In a previous final rule published on March 5, 1999 [Docket No. 
RSPA-98-4185 (HM-215C); 64 FR 10741] PHMSA's predecessor agency, the 
Research and Special Projects Administration (RSPA), aligned the HMR 
with the ICAO Technical Instructions by adding ``Dangerous goods in 
machinery or Dangerous goods in apparatus'' to the HMT. The proper 
shipping name was assigned identification number ``NA8001,'' special 
provision 136 was added for directions on class assignment, and Sec.  
173.222 was added containing requirements applicable to the new entry. 
In the HM-215C rulemaking, RSPA stated that upon the assignment of a UN 
identification number, it would revise the entry accordingly [81 FR 
53935]. This was accomplished in the 11th revised edition of the UN 
Model Regulations, in which identification number UN3363 and Class 9 
were assigned to this entry. The ICAO Technical Instructions were 
amended to be consistent with the UN Model Regulations. Subsequently, 
the HMR was updated accordingly in a final rule published on June 21, 
2001 [Docket No. RSPA-2000-7702 (HM-215D); 66 FR 33315]. While the HMR 
were amended to incorporate the identification number and Class 9 
designation, the quantity limit was not amended to allow up to the 
limited quantity amount authorized by the UN Model Regulations; 
therefore, the ICAO quantity limits were retained for all modes of 
transport.
    In the 20th Revised Edition of UN Model Regulations and Amendment 
39-18 of IMDG Code, the new ``Articles containing hazardous materials, 
n.o.s.'' entries apply to articles which contain only hazardous 
materials that exceed the permitted limited quantity amount for UN3363. 
The ICAO addressed the difference between the quantity authorized in 
the Technical Instructions and both the UN Model Regulations and the 
IMDG Code by amending ICAO special provision A107. The revised special 
provision A107 indicates that where the quantity of dangerous goods 
contained as an integral element in machinery or apparatus exceeds the 
limits permitted by ICAO Technical Instructions Packing Instruction 962 
(same as the existing HMR authorization), and the dangerous goods meet 
the provisions of Special Provision 301 of the UN Model Regulations, 
the machinery or apparatus may be transported as UN3363 only with the 
prior approval of the appropriate authority of the State of Origin and 
the State of the Operator under the written conditions established by 
those authorities.
    In order to more closely align with the UN Model Regulations and 
IMDG Code, for other than air transportation, PHMSA is proposing to 
increase the quantity limits for liquids and solids in paragraph (c) up 
to the limited quantity amount prescribed in the corresponding section 
of Part 173 referenced in Column (8A) of the Sec.  172.101 Table. 
Without this amendment, the HMR would differ from the UN Model 
Regulations and IMDG Code for application of the new ``Articles, 
n.o.s.'' entries, and an approach used by the ICAO Technical 
Instructions would be necessary for all modes. The authorized quantity 
for gases would remain unchanged for all modes of transport.
Section 173.224
    Section 173.224 establishes packaging and control and emergency 
temperatures for self-reactive materials. The Self-Reactive Materials 
Table in paragraph (b)(7) of this section specifies self-reactive 
materials authorized for transportation without first being approved 
for transportation by the Associate Administrator for Hazardous 
Materials Safety, as well as requirements for transporting these 
materials. In paragraph (b)(7), PHMSA proposes to add a new entry 
``Phosphorothioic acid, O-[(cyanophenyl methylene) azanyl] O,O-diethyl 
ester'' to the Self-Reactive Materials Table. In addition, a new ``Note 
5'' assigned to this entry would be added to the list following the 
table.
    Paragraph (c) of this section prescribes requirements for new self-
reactive materials, formulations, and samples. In paragraph (c)(4), 
PHMSA proposes to authorize small samples of certain potentially 
explosive or self-reactive substances when transported for testing 
purposes. These substances usually consist of organic molecules which 
are active ingredients, building blocks, or intermediates for 
pharmaceutical or agricultural chemicals. The molecules of the 
substances often carry functional groups listed in tables A6.1 and/or 
A6.2 in Annex 6 (Screening Procedures) of the UN Manual of Tests and 
Criteria, that would indicate explosive or self-reactive properties; 
however, these substances are not designed to be explosives of Class 1. 
This amendment is necessary

[[Page 60992]]

because during the early development phase of a new product, complete 
test data is often unavailable but the substances must be transported 
for further testing. The provisions proposed in paragraph (c)(4) 
prescribe applicability criteria and packaging conditions for these 
substances to be transported as samples for the purpose of testing. 
These criteria and packaging conditions are based on submissions to the 
UNSCOE on the Transport of Dangerous Goods showing the effectiveness of 
the packaging method proposed in this NPRM.
    Consistent with the UN Model Regulations, PHMSA is proposing to 
revise paragraph (b)(4) to authorize the transportation of self-
reactive substances packed in accordance with packing method OP8 (non-
bulk packaging authorization) where transport in IBCs or portable tanks 
is permitted in accordance with Sec.  173.225, provided that the 
control and emergency temperatures specified in the instructions are 
complied with. This proposed change allows materials that are 
authorized in bulk packagings to also be transported in appropriate 
non-bulk packagings.
Section 173.225
    Section 173.225 prescribes packaging requirements and other 
provisions for organic peroxides. The UN Model Regulations continually 
update their Organic Peroxide Table based on data submitted by 
governments and industry groups with consultative status to account for 
new peroxides and formulations that have become commercially available. 
Consistent with revisions to the UN Model Regulations, PHMSA proposes 
to revise the Organic Peroxide Table in paragraph (c) by adding the 
entries: ``Di-(4-tert-butylcyclohexyl)peroxydicarbonate [as a paste],'' 
``Diisobutyryl peroxide [as a stable dispersion in water],'' and ``1-
Phenylethyl hydroperoxide.'' We propose to revise the Organic Peroxide 
IBC Table in paragraph (e) to maintain alignment with the UN Model 
Regulations by adding new entries for ``Cumyl peroxyneodecanoate, not 
more than 52%, stable dispersion, in water,'' ``2,5-Dimethyl-2,5-
di(tert-butylperoxy)hexane, not more than 52% in diluent type A,'' 
``3,6,9-Triethyl-3,6,9-trimethyl-,4,7-triperoxonane not more than 27% 
diluent type A,'' and ``tert-Amyl peroxy-2-ethylhexanoate, not more 
than 62% in a diluent type A'' and by adding a type 31HA1 IBC 
authorization to the existing entry for ``tert-Butyl hydroperoxide, not 
more than 72% with water.''
    In addition, consistent with the UN Model Regulations, PHMSA is 
proposing that organic peroxides may also be transported packed in 
accordance with packing method OP8 where transport in IBCs or portable 
tanks is permitted, provided that the control and emergency 
temperatures specified in the instructions are complied with.
Section 173.232
    New section 173.232 prescribes requirements for articles not 
otherwise specified by name in the HMR that contain hazardous materials 
of various hazard classes and divisions. This proposal addresses 
situations in which hazardous materials or hazardous materials residues 
are present in articles in quantities greater than the amounts 
authorized for dangerous goods in machinery or apparatus. This proposal 
authorizes a safe method to transport articles that may be too large to 
fit into typical packages. Absent these provisions to package and 
transport these materials safely, these articles may be offered for 
transport under provisions that do not adequately account for the 
physical and chemical properties of the substances and may require the 
issuance of an approval by PHMSA's Associate Administrator for 
Hazardous Materials Safety. PHMSA believes this will be especially 
beneficial to new articles coming to market as they would no longer 
require an approval or an amendment to the Hazardous Materials Table to 
authorize transport.
Section 173.301b
    Section 173.301b describes additional requirements when shipping 
gases in UN pressure receptacles. In paragraph (c)(1), PHMSA is 
proposing to incorporate ISO 17871:2015 containing specification and 
type testing requirements for quick release cylinder valves. In 
paragraph (d)(1), PHMSA is phasing out ISO 13340:2001, Transportable 
gas cylinders--Cylinder valves for non-refillables cylinders--
Specification and prototype testing, which can be utilized until 
December 31, 2020. ISO 13340:2001 is being phased out because the 
applicable valve standard in ISO 13340:2001 has been incorporated into 
ISO 11118:2015.
Section 173.304b
    Section 173.304b contains additional requirements for shipment of 
liquefied compressed gases in UN pressure receptacles. In this NPRM, 
consistent with a change made by in the 20th Revised Edition of the UN 
Model Regulations, PHMSA is proposing to amend paragraph (b)(5) by 
replacing ``liquid phase'' with ``liquefied gas'' and ``compressed'' 
with ``compressed gas'' to better describe the phases of the material 
being stored and to align with the UN language.
Section 173.422
    Section 173.422 contains additional requirements for excepted 
packages containing Class 7 (radioactive) materials. Shipments of 
excepted packages containing Class 7 materials are not required to meet 
the general shipping paper requirements found in the HMR. Amendments 
39-18 of the IMDG Code adopted a requirement that vessels carrying 
these excepted packages include information concerning these packages 
(e.g., UN ID Number and location on board the vessel) on the Dangerous 
Cargo Manifest (DCM). Historically, the HMR has not required any 
documentation to accompany shipments of excepted packages containing 
radioactive material when offered for transportation by vessel. In this 
NPRM, PHMSA proposes to amend the DCM requirements in Sec.  173.60 to 
require information about these shipments to be included in the DCM 
carried aboard the vessel. Without a corresponding amendment to Sec.  
173.422 to require the information to be provided to the vessel 
operator, the vessel operator would not have the information available 
that would be required to be included on the DCM.
    In this NPRM, PHMSA proposes to add a new paragraph (f) that would 
require excepted packages of radioactive materials offered for 
transportation by vessel to have a special transport document such as a 
bill of lading, air waybill, or other similar document that includes 
the UN identification number for the material being offered, the name 
and address of the consignor and consignee, and a container packing 
certificate, in accordance with the requirements in Sec.  176.27. This 
proposed amendment provides for the conveyance of necessary information 
to the vessel operator for creation of the DCM.

Part 174

Section 174.50
    Section 174.50 prescribes regulations for the movement of 
nonconforming or leaking packages by rail. Under the HMR, no person may 
offer for transportation or transport a bulk hazmat packaging 
(typically a tank car) by rail unless that packaging is marked, 
represented, maintained, reconditioned, repaired, and retested in 
accordance with the HMR (Sec.  171.2(g)). However, Sec.  174.50 
authorizes the movement of a

[[Page 60993]]

non-conforming bulk hazmat package moved by rail when: (1) The movement 
is necessary to reduce or eliminate an immediate threat or harm to 
human health or the environment; or (2) the movement is approved by the 
Federal Railroad Administration's (FRA's) Associate Administrator for 
Railroad Safety.
    Approvals issued by FRA's Associate Administrator for Railroad 
Safety are commonly referred to as One-Time Movement Approvals 
(OTMAs).\6\ Transport Canada issues similar approvals for the movement 
of non-conforming bulk hazmat packages and tank cars, which are 
referred to as Temporary Certificates. Historically, for movements of 
non-conforming tank cars from Canada to or through the United States, 
the offeror would have to obtain both an OTMA from FRA and a Temporary 
Certificate from Transport Canada. These applications initiate 
administrative processes and safety reviews by both governments that 
nearly always result in the same conclusion. Since the safety analysis 
used to evaluate Temporary Certificates in Canada is similar to the 
safety analysis used to evaluate OTMAs by FRA, the requirement to 
obtain two government approvals for a cross border movement provides no 
additional safety benefit and is redundant and burdensome. Thus, to 
facilitate cross border trade, for movements to or through the United 
States from Canada, PHMSA proposes to amend the regulation to recognize 
Temporary Certificates issued by Transport Canada. This amendment would 
reduce the duplicative requirement to apply for both an OTMA from the 
United States and a Temporary Certificate from Canada, should the non-
conforming package need to be transported over the United States-
Canadian border.
---------------------------------------------------------------------------

    \6\ On October 7, 2014 FRA issued guidance on One-Time Movement 
Approvals titled One-Time Movement Approval Procedures, HMG-127.
---------------------------------------------------------------------------

    On July 12, 2007, Transport Canada published, ``Regulations 
Amending the Transportation of Dangerous Goods Regulations 
(International Harmonization Update, 2016).'' In this publication, 
Transport Canada indicated that recognition of OTMA may be included in 
a future amendment. This amendment aims to facilitate international 
transportation and at the same time ensures the safety of people, 
property, and the environment. Finally, for low-risk movements of non-
conforming tank cars, Transport Canada authorizes the one-time movement 
without the need to obtain a temporary certificate (see TP-14877). For 
clarification, such movements under the TDG Regulations are already 
authorized by Sec.  171.12, provided the movements are compliant with 
all applicable requirements in the TDG Regulations and Sec.  171.12.

Part 175

Section 175.10
    Section 175.10 specifies the conditions for which passengers, crew 
members, or an operator may carry hazardous materials aboard an 
aircraft. Consistent with revisions to the ICAO Technical Instructions, 
in this NPRM, PHMSA is proposing several revisions to this section.
    PHMSA proposes to revise paragraph (a)(2) to account for lighters 
powered by lithium batteries (e.g., laser plasma lighters, tesla coil 
lighters, flux lighters, arc lighters, and double arc lighters). The 
assigned provisions would be consistent with a combination of the 
existing requirements applicable to portable electronic devices powered 
by lithium batteries and battery powered portable electronic smoking 
devices. Specifically, each lithium battery must be of a type which 
meets the requirements of each test in the UN Manual of Tests and 
Criteria, Part III, Subsection 38.3 and must not exceed the size limits 
authorized for portable electronic devices. Recharging of the devices 
and/or the batteries on board the aircraft is not permitted consistent 
with the requirements for portable electronic smoking devices. In 
addition, lithium battery powered lighters without a safety cap or 
means of protection against unintentional activation are prohibited in 
carry-on baggage, checked baggage, and as when carried on one's person.
    PHMSA proposes to revise paragraph (a)(3), to authorize medical 
devices containing radioactive material fitted externally as the result 
of medical treatment, consistent with the ICAO Technical Instructions. 
In addition, the reference to implanted medical devices containing 
lithium batteries would be removed. For medical devices containing 
lithium batteries (including those implanted, externally fitted, or 
carried by passengers or crew members) the quantity limits provided in 
(a)(18)(i) or (ii) apply, as applicable.
    PHMSA proposes to revise paragraph (a)(14) for consistency with the 
ICAO Technical Instructions and other paragraphs in this section. The 
first sentence is revised to clarify that the paragraph is applicable 
to battery powered heat-producing devices rather than ``electrically 
powered'' articles. For lithium battery powered devices, quantity 
limits would be added in new paragraphs (i) and (ii) consistent with 
the existing requirements applicable to portable electronic devices 
powered by lithium batteries and battery powered portable electronic 
smoking devices. The requirements for spare batteries would be revised 
to reference the provisions for spare batteries in paragraph (a)(18).
    PHMSA proposes to revise paragraph (a)(15) by adding a new 
paragraph (vi) to separate and clarify the handling requirements 
applicable to each ``non-spillable'' and ``dry sealed'' batteries both 
presently prescribed in paragraph (v). PHMSA also proposes to add a new 
paragraph (vii) to authorize passengers with restricted mobility to 
carry a spare non-spillable or dry sealed battery for their mobility 
aid. Presently, spare lithium batteries are permitted for passengers 
with lithium battery-powered mobility aids; this was deemed acceptable 
for mobility aids equipped with non-spillable or dry sealed batteries.
    PHMSA proposes to amend provisions for carriage of wheelchairs or 
other mobility aids equipped with a lithium ion battery by removing the 
requirement that ``collapsible'' mobility aids necessitate removal of 
the battery. The intent of the existing requirement was to allow the 
removal of the batteries from lightweight collapsible mobility aids 
when these do not afford any protection to the batteries. However, the 
existing text in both the HMR and ICAO Technical Instructions can be 
construed to mean that if the battery was designed to be removable from 
the mobility aid, that it must be removed in all circumstances, even 
when adequate protection to the batteries is provided. In cases when 
the batteries are adequately protected, it is preferable that they 
remain installed in the mobility aid; however, there may be situations 
when that is not possible or safe to do so and in these cases the 
batteries must be removed. Therefore, in this NPRM, PHMSA is proposing 
to amend (a)(17)(v) by removing the word ``collapsible'' and clarifying 
that when the wheelchair or mobility aid does not provide adequate 
protection to the battery, that the battery must be removed and handled 
in accordance with the existing conditions prescribed in (a)(17)(v)(A) 
through (E).
    PHMSA proposes to amend the provisions for carriage of personal 
electronic devices (PEDs) containing lithium batteries to address 
safety concerns related to recent security restrictions requiring 
passengers to carry personal electronic devices in checked baggage. 
Consistent with the ICAO

[[Page 60994]]

Technical Instructions, Sec.  175.10(a)(18) would be revised to require 
that when portable electronic devices powered by lithium batteries are 
in checked baggage, they must be completely powered off and protected 
to prevent unintentional activation or damage.
    PHMSA proposes to revise the carriage requirements for battery-
powered portable electronic smoking devices in paragraph (a)(19). The 
2015-2016 Edition of the ICAO Technical Instructions incorporated 
provisions prohibiting passengers and crew from carrying such devices 
in checked baggage or recharging them in the cabin, and requiring that 
any spare batteries be protected from short circuit. In a working paper 
submitted by the United States at ICAO DGP/26 meeting, it was reported 
that even after the prohibition, ten incidents involving these devices 
were documented between May 2015 and May 2017. As described in the 
working paper, seven of the incidents occurred inside a passenger 
aircraft and three occurred inside an airport. These incidents 
typically involved the electronic smoking device while it was being 
transported in carry-on baggage, with the suspected cause of the 
majority of these incidents being the accidental activation of the 
device. Specifically, in this NPRM, PHMSA is proposing to align the HMR 
with the ICAO Technical Instructions by requiring passengers or crew to 
take effective measures for preventing accidental activation of the 
heating element of the device when transporting such devices in carry-
on baggage on board passenger aircraft. Examples of effective measures 
include, but are not limited to: Removing the battery from the 
electronic smoking device; separating the battery from the heating 
coil; placing the electronic smoking device into a protective case; 
using a protective cover, safety latch, or locking device on the 
electronic smoking device's heating coil activation button; and 
electronics or technology in the device designed to prevent accidental 
activation, such as those requiring the electronic smoking device to be 
powered on before the heating coil button can be activated. In most 
electronic smoking devices, the battery can either be easily removed or 
easily separated from the heating element.
    PHMSA proposes to add a new paragraph (a)(26) that would amend the 
passenger provisions for carriage of baggage equipped with lithium 
batteries (e.g., smart baggage) intended to power features designed to 
make travel easier, such as location tracking, PED battery charging, 
short range wireless connections, digital weighing, or motors. To 
address concerns that passengers would check baggage containing lithium 
batteries (e.g., power banks) despite existing requirements that 
articles whose primary purpose is to provide power to another device be 
carried as spare batteries in the cabin as carry-on baggage, the ICAO 
Technical Instructions were amended to require that passengers remove 
lithium batteries from baggage they intend to check, in accordance with 
the provisions for spare batteries. Specifically, baggage equipped with 
a lithium battery or batteries would be required to be carried as 
carry-on baggage, unless the battery or batteries are removed from the 
baggage. Once the battery or batteries are removed from baggage 
intended to be checked, the battery or batteries must be carried in the 
cabin in accordance with the provisions for spare batteries prescribed 
in paragraph (a)(18). This restriction in checked baggage would not 
apply to baggage containing lithium metal batteries with a lithium 
content not exceeding 0.3 grams, or lithium ion batteries with a Watt-
hour rating not exceeding 2.7 Wh.
Section 175.33
    Section 175.33 establishes requirements for shipping papers and for 
the notification of the pilot-in-command when hazardous materials are 
transported by aircraft. In paragraph (a)(11), applicable to ``UN 1845, 
Carbon dioxide, solid (dry ice),'' PHMSA proposes that the text 
``hold'' be replaced with the word ``cargo compartment.'' This would be 
consistent with use of the term ``compartment'' in other areas of the 
HMR and ICAO Technical Instructions. Consistent with revisions to the 
ICAO Technical Instructions, in paragraph (a)(13)(i), PHMSA proposes to 
include the airport at which the lithium batteries will be unloaded on 
the information to the pilot-in-command when a summary is used for 
lithium batteries. Including the airport at which the batteries will be 
unloaded is consistent with the authorization to use a summary instead 
of the default information to the pilot in command for ``UN 1845, 
Carbon dioxide, solid (dry ice).''
Section 175.78
    Section 175.78 prescribes the stowage compatibility of hazardous 
materials offered for transportation by aircraft. Consistent with 
international standards, in a March 30, 2017, final rule [HM-215N; 82 
FR 15795], PHMSA added new Class 3 HMT entry ``UN 3528,'' applicable to 
the fuel contained in engines and machinery powered by Class 3 
flammable liquids. In accordance with the segregation requirements 
prescribed in this section, engines and machinery classified under the 
new UN 3528 entry in Class 3 are required to be segregated from 
dangerous goods with a primary or subsidiary hazard of Division 5.1. 
Prior to the addition of the UN 3528 HMT entry, such engines and 
machinery were classed in Class 9 and therefore not required to be 
segregated from Division 5.1 materials. The packing requirements by air 
for UN 3528 require engines to be drained and the tank caps fitted 
securely. These precautions ensure that there is only a negligible 
amount of residual fuel remaining. There is no indication that, as 
prepared for transport, UN 3528 poses any more hazard now that would 
require these items to be segregated than when these items were 
previously identified as a Class 9. Therefore, in this NPRM, PHMSA is 
proposing to add an exception from the segregation requirement by 
adding a ``Note 3'' to the paragraph (b) Segregation Table and adding a 
new paragraph (c)(8) stating that materials consigned under UN 3528 
need not be segregated from packages containing hazardous materials in 
Division 5.1.
    Consistent with the ICAO Technical Instructions, PHMSA is proposing 
to require that packages and overpacks containing lithium cells and 
batteries that bear the Class 9 label must not be stowed on an aircraft 
next to, in contact with, or in a position that would allow interaction 
with, packages or overpacks containing other hazardous materials in 
Class 1 (other than Division 1.4S), Division 2.1, Class 3, Division 4.1 
and Division 5.1. Specifically, the current paragraph (b) would be 
reformatted into two paragraphs. A new paragraph (b)(2) would be added 
to prescribe the segregation requirements applicable to lithium cells 
and batteries. The existing Segregation Table would be revised by 
adding the necessary columns and rows representing hazard classes not 
presently in the Table. These changes to the Table would indicate that 
hazardous materials in the classes described above must be segregated 
from packages and overpacks containing lithium cells or batteries 
prepared in accordance with Sec.  173.185(b)(3) and (c)(4)(vi). PHMSA 
is proposing this action to promote consistency with the ICAO Technical 
Instructions and in response to a recommendation (A-16-001) from the 
National Transportation Safety Board (NTSB) stemming from the 
investigation of the July 28, 2011, in-flight fire and crash of Asiana 
Airlines Flight 991 that resulted in the loss of the aircraft and

[[Page 60995]]

crew. The investigation report cited as a contributing factor the 
flammable materials and lithium ion batteries that were loaded together 
either in the same or adjacent pallets.

Part 176

Section 176.30
    Section 176.30 prescribes requirements for DCM's, lists, or stowage 
plans required to be carried aboard vessels transporting hazardous 
materials. In this NPRM, PHMSA is proposing to add a new paragraph 
(a)(9) to require that DCMs include information on shipments of 
excepted packages containing Class 7 materials. For shipments of 
excepted packages containing Class 7 material only the UN 
identification number, the name and address of the consignor and the 
consignee, and the stowage location of the hazardous material on board 
the vessel would be required to be entered on the DCM, list, or stowage 
plan carried aboard the vessel.
Section 176.84
    Section 176.84 prescribes the meanings and requirements for 
numbered or alphanumeric stowage provisions for vessel shipments listed 
in column (10B) of the Sec.  172.101 HMT. The provisions in Sec.  
176.84 are broken down into general stowage provisions, which are 
defined in the ``table of provisions'' in paragraph (b), and the 
stowage provisions applicable to vessel shipments of Class 1 
explosives, which are defined in the table in paragraph (c)(2). In a 
previous final rule [Docket No. PHMSA-2015-0273 (HM-215N); 82 FR 
15796], a subsidiary hazard of 6.1 was added to the UN 2977 and UN 2978 
uranium hexafluoride entries, and the primary hazard for UN 3507, 
Uranium hexafluoride, radioactive material, excepted package was 
changed from 8 to 6.1. Consequential amendment to the stowage and 
segregation requirements codes for these materials were not addressed 
at the time of these changes in the IMDG Code or the HMR. In this NPRM, 
we propose to create new stowage provisions that clarify what 
segregation requirements apply to shipments of uranium hexafluoride.
    PHMSA proposes to create a new stowage provision 151 and assign it 
to the UN 2977 and UN 2978 uranium hexafluoride entries. This new 
stowage provision will require segregation for Class 7 materials to 
apply to uranium hexafluoride shipped under these two UN numbers.
    Additionally, consistent with Amendment 39-18 of the IMDG Code, 
PHMSA proposes to create a new stowage provision 152 and assign it to 
UN 3507, Uranium hexafluoride, radioactive material, excepted package. 
This proposed new stowage provision requires segregation as for Class 
8, but excepts segregation in relation to Class 7 materials. This 
exception to the general segregation requirements between Class 8 and 
Class 7 materials allows shipments of excepted packages of uranium 
hexafluoride to be stowed in close proximity to shipments of fully 
regulated uranium hexafluoride.
    Based on changes to the IMDG Code to address the appropriate 
segregation requirements for shipments of uranium hexafluoride, PHMSA 
proposes to create a new stowage provision 153 and assign it to the UN 
2977 and UN 2978 uranium hexafluoride HMT entries. This proposed new 
stowage provision requires these materials to be stowed ``separated 
longitudinally by an intervening complete compartment or hold from'' 
Divisions 1.1, 1.2, and 1.5.
    Based on changes to the IMDG Code to provide additional flexibility 
in the stowage requirements for jet perforating guns, PHMSA proposes to 
create a new stowage provision 154 and assign it to the NA 0123, NA 
0494, UN 0494, and UN 0124 jet perforating gun HMT entries. This 
proposed new stowage provision indicates that, notwithstanding the 
stowage category assigned to the entries in the HMT, jet perforating 
guns may be stowed in accordance with the provisions of packing 
instruction US 1 in Sec.  173.62. These jet perforating guns are 
currently assigned to stowage categories ``02'' and ``04.'' Both 
stowage categories require stowage in closed cargo transport units. The 
inclusion of new stowage provision 154 clarifies that regardless of the 
stowage category assigned, jet perforating guns offered in accordance 
with US 1 in Sec.  173.62 are not required to be offered for transport 
or transported in closed cargo transport units.

Part 178

Section 178.71
    Section 178.71 prescribes specifications for UN pressure 
receptacles. Consistent with the UN Model Regulations, PHMSA proposes 
to amend paragraphs (d)(2), (i), (j), and (q)(12), to reflect the 
adoption of the latest ISO standards for the design, construction, and 
testing of gas cylinders and their associated service equipment. In 
paragraph (d)(2), PHMSA is proposing to phase out ISO 13340:2001, which 
is authorized for valves manufactured until December 31, 2020, and to 
incorporate by reference ISO 14246:2014 (E) ``Gas cylinders--Cylinder 
valves--Manufacturing tests and examination'', which addresses initial 
inspection and testing requirements for valves. ISO 13340:2001 is being 
phased out because the applicable valve has been incorporated into ISO 
11118:2015. In paragraph (f), PHMSA is proposing to amend the title of 
the paragraph to include pressure drums and to add ISO 21172-1:2015(E), 
``Gas cylinders--Welded steel pressure drums up to 3 000 litres 
capacity for the transport of gases--Design and construction--Part 1: 
Capacities up to 1 000 litres'' in new paragraph (f)(4). A note was 
added to the UN Mode Regulations that authorizes welded steel gas 
pressure drums with dished ends convex to pressure to be used for the 
transport of corrosive substances provided all applicable additional 
requirements are met, irrespective of section 6.3.3.4 of this standard 
which prohibits such use. Therefore, PHMSA is proposing the same 
deviation from the ISO standard in (p).
    In addition, in paragraph (i), PHMSA is proposing to phase out ISO 
11118:1999 ``Gas Cylinders for Non-refillable Metallic Gas Cylinders,'' 
which is authorized until December 31, 2022, and to replace it with new 
standard, ISO 11118:2015. In paragraph (j), PHMSA is proposing to phase 
out ISO 111120:1999, ``Gas Cylinders for Refillable Seamless Steel 
Tubes,'' which is authorized until December 31, 2022, and to replace it 
with ISO 111120:2015. In paragraph (q)(12), PHMSA is incorporating ISO/
TR 11364, ``Gas cylinders--Compilation of national and international 
valve stem/gas cylinder neck threads and their identification and 
marking system'' to specify a harmonized identification code and 
marking system for both cylinders and valves.
Section 178.75
    Section 178.75 prescribes specifications for MEGCs. In paragraph 
(d)(3)(v), PHMSA is proposing to phase out ISO 11120:1999, which is 
authorized for construction and testing of receptacles of MEGCs until 
December 31, 2020, and to authorize the new, updated standard ISO 
11120:2015. Changes to the new edition of this standard include the 
addition of an annex outlining typical chemistry groupings for seamless 
steel tubes, the addition of nickel chromium molybdenum steel, the 
modification of ultrasonic examination provisions, and revisions to the 
provisions for the design of tubes for embrittling gases.

[[Page 60996]]

Section 178.601
    Section 178.601 prescribes the general requirements for test 
procedures for non-bulk packagings and packages. A test report must be 
prepared and made available to a user of a packaging or a DOT 
representative upon request. In this NPRM, PHMSA is proposing to 
require in paragraph (l)(2)(viii) that the test report for plastic 
packagings that are subject to the hydraulic pressure test must include 
the temperature of the water used for the test. Tests with different 
water temperatures applied to one design type can produce different 
test results (pass or fail). This action is consistent with amendments 
to the UN Model Regulations.
Section 178.801
    Section 178.801 prescribes the general requirements for test 
procedures of an IBC containing a hazardous material. A test report for 
an IBC must be prepared and made available to a user of a packaging or 
a DOT representative upon request. In this NPRM, PHMSA is proposing to 
require in paragraph (l)(2)(viii) that the test report for rigid 
plastics and composite IBCs that are subject to the hydraulic pressure 
test must include the temperature of the water used for the test. Tests 
with different water temperatures applied to one design type can 
produce different test results (pass or fail). The inclusion of the 
temperature of the water used for the test will allow for tests that 
more accurately simulate the original design type testing when such 
additional testing is performed.
Section 178.810
    Section 178.810 prescribes the requirements for an IBC drop test. 
In paragraph (c)(1), PHMSA proposes to clarify that the same IBC or a 
different IBC of the same design type may be utilized for the required 
drop tests.

Part 180

Section 180.207
    Section 180.207 prescribes requirements for requalification of UN 
pressure receptacles. In March 2017, PHMSA published a final rule under 
Docket HM-215N [82 FR 15796 (March 30, 2017)]. In this rule, PHMSA 
amended the HMR to expand recognition of cylinders and pressure 
receptacles, cargo tank repair facilities, and certificates of 
equivalency in accordance with the Transport Canada TDG Regulations. 
The goal of these amendments is to promote flexibility and permit the 
use of advanced technology for the requalification and use of pressure 
receptacles, to provide for a broader selection of authorized pressure 
receptacles, reduce the need for special permits, and to facilitate 
cross-border transportation of these cylinders. In the HMR in Sec.  
171.12 (a)(4) permit the transportation of a cylinder authorized by 
Transport Canada TDG Regulations to, from, or within the United States. 
In HM-215N, PHMSA amended (a)(4)(ii) to authorize the use of Canadian 
manufactured cylinders. Specifically, PHMSA authorized the 
transportation of CTC, CRC, BTC, and TC cylinders that have a 
corresponding DOT specification cylinder prescribed in the HMR. HM-215N 
did not remove or amend existing requirements for DOT specification 
cylinders; rather, PHMSA is providing that a shipper may use either a 
DOT specification cylinder or a TC cylinder, as appropriate.
    In this NPRM, PHMSA proposes to clarify the amendments in HM-215N 
and allow for the requalification of ``CAN'' marked UN cylinders in the 
United States. Cylinders marked with the letters ``CAN'' for Canada as 
a country of manufacture or a country of approval may be requalified in 
the United States, provided the requirements in Sec. Sec.  178.69, 
178.70, and 178.71, as applicable, are met. This amendment aims to 
facilitate international transportation, while ensuring the safety of 
people, property, and the environment
    Consistent with changes to the UN Model Regulations, PHMSA proposes 
to revise paragraph (d)(1) to incorporate ISO 16148:2016, which 
addresses the requalification of seamless steel cylinders and tubes. 
This proposed addition will allow the internal inspection and hydraulic 
pressure test for seamless steel ISO cylinders and tubes to be replaced 
by non-destructive testing methods identified in ISO 16148:2018. 
Additionally, in paragraph (d)(4), PHMSA is proposing to phase out ISO 
11623:2002, which is authorized for inspection and testing of composite 
UN cylinders until December 31, 2020, and authorizing the new standard, 
ISO 11623:2015. Finally, PHMSA proposes adding new paragraph (d)(6) to 
incorporate inspection and maintenance requirements for cylinder valves 
preformed during requalification, as found in ISO 22434:2006 
``Transportable gas cylinders--Inspection and maintenance of cylinder 
valves.'' Changes to the revised standard include; up-to-date 
terminology particularly for the various types of composite cylinders, 
up-to-date normative references for steel and aluminum-alloy liner 
materials, and an update of some photographs to provide sharper 
examples of damage.

VII. Regulatory Analyses and Notices

A. Statutory/Legal Authority for This Rulemaking

    This proposed rule is published under the statutory authority of 
Federal hazardous materials transportation law (49 U.S.C. 5101 et 
seq.). Section 5103(b) of Federal hazmat law authorizes the Secretary 
of Transportation to prescribe regulations for the safe transportation, 
including security, of hazardous materials in intrastate, interstate, 
and foreign commerce. This proposed rule would amend regulations to 
maintain alignment with international standards by incorporating 
various amendments, including changes to proper shipping names, hazard 
classes, packing groups, special provisions, packaging authorizations, 
air transport quantity limitations, and vessel stowage requirements. To 
this end, the proposed rule amends the HMR to more fully align with the 
biennial updates of the UN Model Regulations, the IMDG Code, and the 
ICAO Technical Instructions.
    The following external agencies were consulted in the development 
of this rule:
     Federal Aviation Administration;
     Federal Motor Carrier Safety Administration;
     Federal Railroad Administration; and
     U.S. Coast Guard.
    Section 49 U.S.C. 5120(b) of Federal hazmat law authorizes the 
Secretary to ensure that, to the extent practicable, regulations 
governing the transportation of hazardous materials in commerce are 
consistent with standards adopted by international authorities. This 
rule proposes to amend the HMR to maintain alignment with international 
standards by incorporating various amendments to facilitate the 
transport of hazardous material in international commerce. To this end, 
as discussed in detail above, PHMSA proposes to incorporate changes 
into the HMR based on the 20th Revised Edition of the UN Model 
Regulations, Amendment 39-18 to the IMDG Code \7\, and the 2019-2020 
Edition of the ICAO Technical Instructions, which become effective 
January 1, 2019. The large volume of hazardous materials transported in 
international commerce warrants the harmonization of domestic and 
international requirements to the greatest extent possible.
---------------------------------------------------------------------------

    \7\ Amendment 39-18 to the IMDG Code may be voluntarily applied 
on January 1, 2019; however, the previous amendment remains 
effective through December 31, 2019.

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

B. Executive Order 12866, Executive Order 13563, and DOT Regulatory 
Policies and Procedures

    This notice is not considered a significant regulatory action under 
section 3(f) of Executive Order 12866 (``Regulatory Planning and 
Review'') and, therefore, was not reviewed by the Office of Management 
and Budget. This notice is not considered a significant rule under the 
Regulatory Policies and Procedures of the Department of Transportation 
(44 FR 11034).
Cost-Reducing Aspects of Harmonization
    General Harmonization Benefit: Given current available information, 
PHMSA has developed an estimate of the avoided compliance costs of 
harmonization, and discusses and requests comment on additional 
benefits.
    To estimate the benefits to affected industries from avoided 
compliance costs, PHMSA relies on a benefit-transfer value of the 
hazard communication cost savings utilized in previous PHMSA 
international harmonization rulemakings \8\, based on an Occupational 
Safety and Health Administration (OSHA) study. The original rulemaking 
harmonized U.S. regulations with international standards so that 
industry did not have to adhere to two separate hazard communication 
systems.\9\ This value--$0.001 per dollar of hazardous materials 
output--is based on OSHA's estimate of the costs for industry to comply 
with the revised Hazard Communication Standard \10\ and an estimate of 
the value of hazardous material in trade. The savings then accrue to 
all exporters, who would otherwise incur theses costs of hazard 
communication.
---------------------------------------------------------------------------

    \8\ PHMSA's harmonization rulemakings, HM-215M: Hazardous 
Materials: Harmonization with International Standards (RRR), Final 
Rule, 80 FR 1075, January 8, 2015 and HM-215N: Hazardous Materials: 
Harmonization with International Standards (RRR), 82 FR 15796, March 
30, 2017
    \9\ Department of Transportation, Pipeline and Hazardous 
Materials Safety Administration. Hazardous Materials: Harmonization 
with International Standards (RRR), Final Rule, 78FR 987, January 7, 
2013; p. 1023.
    \10\ OSHA's estimate relied on comparing the costs of complying 
with the revised Hazard Communication Standard to the overall output 
of hazardous materials. The study measured four cost elements: 
revisions to labels and safety data sheets, additional training, 
additional management activities, and printing of color packaging. 
PHSMA determined that only the first three cost elements were 
relevant for harmonization purposes, and estimated the value of 
these costs as a fraction of the total value of hazardous materials 
produced in the United States to determine the $0.001 per dollar of 
hazardous materials output.
---------------------------------------------------------------------------

    Using this estimate of the avoided hazard communication costs, 
PHMSA estimated the potential benefits to exporters of harmonizing the 
HMR with international standards. PHMSA relied on the 2012 Bureau of 
Economic Analysis' (BEA) International Accounts Products for Detailed 
Goods Trade Data to value industry imports and exports.\11\
---------------------------------------------------------------------------

    \11\ Bureau of Economic Analysis, U.S. Department of Commerce, 
U.S. Trade in Goods (IDS-0008), available at: http://www.bea.gov/international/detailed_trade_data.htm.
---------------------------------------------------------------------------

    PHSMA updated our estimate of value of hazardous materials involved 
in international trade by using U.S. trade in goods seasonally 
adjusted, Census-based total gross imports, and gross exports in the 
fuels and lubricants, chemicals, and medicinal/dental/pharmaceutical 
products industries for the 2016, the most recent year available.
     Gross imports: $343.431 billion.
    [cir] Fuels and lubricants: $162.077 billion.
    [cir] Chemicals: $69.655 billion.
    [cir] Medicinal/dental/pharmaceutical products: $111.700 billion.
     Gross exports: $269.518 billion.
    [cir] Fuels and lubricants: $112.462 billion.
    [cir] Chemicals: $103.779 billion.
    [cir] Medicinal/dental/pharmaceutical products: $53.277 billion.
     Gross imports plus gross exports: $612.949 billion.
    For estimating benefits of this topic, according to the 2012 CFS, 
commodities worth $13,852,143 million were transported in the U.S. in 
2012, of which $2,334,425 million worth were hazardous (or 16.9 
percent).\12\ However, the 16.9 percent proportion (of total shipment 
values classed as hazardous materials) estimated may have had a high-
side bias due to the variety of different classes of products 
classified as hazardous. The percentage of shipments properly 
classified as hazardous is likely lower, particularly for medicinal/
dental/pharmaceuticals (for this analysis PHSMA assume 10 percent).
---------------------------------------------------------------------------

    \12\ U.S. Department of Transportation & U.S. Department of 
Commerce (2015). Hazardous Materials 2012 Economic Census, 
Transportation, 2012 Commodity Flow Survey, available at: https://www.census.gov/econ/cfs/2012/ec12tcf-us-hm.pdf [see Table 1a].
---------------------------------------------------------------------------

    Multiplying this $613 billion (rounded) figure by 10 percent (the 
estimated proportion of annual trade in these three industries that are 
hazardous products) by the average hazard communication cost per dollar 
of hazardous materials produced in the United States ($0.001) results 
in an estimate of benefits of $61.2 million (rounded) annually. Over 
the ten-year analysis period from 2019 to 2028, this equates to a net 
present value of $431 million to $522 million, using a 7 percent and 3 
percent discount rate, respectively.
    Because it is difficult to directly compare the scope and nature of 
changes made in the OSHA rule with those made by PHMSA in each HM-215 
rulemaking series, the estimates developed should be considered 
illustrative of very rough and highly uncertain impacts of general 
harmonization, Given the high degree of uncertainty in these estimates, 
due to the inability of PHMSA to align provisions in this rule, and 
their potential impacts, with the OSHA rule we use to draw our estimate 
from, we do not consider these quantified cost savings, averted costs, 
or benefits. PHMSA requests comments on the general harmonization 
benefit methodology utilized as well as any qualitative or quantitative 
information that our stakeholders can provide on the impact of general 
harmonization to their operations.
    Corrosivity Classification: Current regulations require shippers to 
classify Class 8 materials to a packing group based on animal test data 
or to utilize authorized in vitro test methods. However, these 
regulations require that data obtained from the testing qualify as the 
only acceptable data for the classification and assignment to a packing 
group. The proposed addition of Sec.  173.137(d) provides alternative 
packing group assignment methods to classify corrosive mixtures that 
does not involve physical testing. The proposed tiered approach to 
classification and packing group assignment depends on how much 
information is available for the mixture itself, similar mixtures, and/
or its ingredients. Specifically, the proposed amendments include the 
following methods of classification for mixtures: Dilution, batching, 
criteria for substantially similar mixtures, and a calculation method 
using existing data for the component substances of the mixture.
    PHMSA expects there to be cost savings to shippers of mixtures that 
chose to classify their materials using the new classification options 
instead of traditional testing methods (e.g. in-vitro or in-vivo). 
Traditional skin corrosion testing involving animals costs 
approximately $1,800. Whereas, the alternative in-vitro tests range 
from $500 to $850, 13 14 with a median cost of $675.

[[Page 60998]]

The new classification methods for mixtures are faster and demonstrate 
an equivalent level of safety at a much lower cost. PHSMA expects that 
many shippers of Class 8 materials will use the new regulatory 
flexibility to utilize the lower cost, non-testing alternatives.
---------------------------------------------------------------------------

    \13\ Humane Society International. Costs of Animal and Non-
Animal Testing. http://www.hsi.org/issues/chemical_product_testing/facts/time_and_cost.html.
    \14\ These skin corrosion tests are named the Draize rabbit skin 
test for $1,800, EpiDerm human skin model in vitro test for $850, 
and the CORROSITEX membrane barrier for $500.
---------------------------------------------------------------------------

    These non-test methods have varying degrees of time required for 
determination of a classification. Methods such as dilution and 
batching are relatively straight forward and require minimal time to 
arrive at a classification determination. Methods such as bridging and 
calculation require more time to arrive at a classification 
determination. PHMSA does not have a reliable estimate of the time to 
perform these non-test classification methods. For the purposes of this 
analysis, we have utilized the most time-consuming calculation method. 
To arrive at a classification determination using the calculation 
method the person preforming the calculation must utilize data on the 
known components of the mixture, and using a formula arrive at a number 
that correlates to an assignment of a packing group. PHMSA assumes that 
data on components of a mixture will generally be available, and that 
preforming this calculation takes approximately 3 hours to complete. 
Utilizing a weighted hourly wage of $79.06, \15\ PHMSA estimates a cost 
of $237.18 for preforming the calculation method to arrive at a 
corrosivity classification determination. The median cost of currently 
authorized in-vitro and in-vivo testing is $1,237.5. This represents a 
cost savings of $1,000.32 per test.
---------------------------------------------------------------------------

    \15\ Occupation labor rates based on 2017 Occupational and 
Employment Statistics Survey (OES) for ``Chemical Engineers (17-
2041)'' in the Chemical Manufacturing industry. The hourly mean wage 
for this occupation ($54) is adjusted to reflect the total costs of 
employee compensation based on the BLS Employer Costs for Employee 
Compensation Summary, which indicates that wages for civilian 
workers are 68.3 percent of total compensation (total wage = wage 
rate/wage % of total compensation).
---------------------------------------------------------------------------

    PHSMA is challenged in monetizing total cost savings due to a lack 
of data describing baseline conditions, including a breakdown of the 
types of hazardous materials that make up the 2012 CFS total flow 
estimates and the total number of traditional tests industry currently 
conducts annually to comply with Sec.  173.137. In addition, PHSMA does 
not have enough information to predict how this proposed rulemaking 
will change industry behavior. Absent more definitive data, PHMSA 
assumes 500 to 3,000 new mixtures tested per year. If all of these 
mixtures use the new non-testing methods, and cost savings equal 
$1,000.32 per test, total industry cost savings could equate to $0.4 to 
$3.9 million dollars per year. PHSMA seeks comment if these numbers 
represent an accurate estimate of new mixtures tested annually.
Costs of Harmonization
    Please see the RIA for this rulemaking--a copy of which has been 
placed in the docket--for detailed analysis of the costs of various 
amendments proposed in this NPRM. Additionally, where noted below, 
please see the Paperwork Reduction Act section of this rulemaking for a 
detailed discussion of applicable proposals.
    Requiring 6(d) testing for certain explosives: PHMSA believes that 
requiring additional tests will result in greater costs for 
manufacturers of explosives presently approved for transport under 
UN0349, UN0367, UN0384, or UN0481. Please see the Paperwork Reduction 
Act section of this rulemaking for a detailed discussion of these 
estimated costs.
    Lithium Battery Test Summary: PHMSA believes that the proposed 
creation of a lithium cell or battery test summary and the proposed 
requirement for subsequent distributors to make the test summary 
available will result in costs to cell and battery manufacturers, as 
well as subsequent distributors. Please see the Paperwork Reduction Act 
section of this rulemaking for a detailed discussion of these estimated 
costs.
Net Benefit
    Based on the discussions of benefits and costs provided above, 
PHMSA estimates discounted net cost savings at 3 percent discount rate 
of approximately $97,000-$2.2 million per year and at 7 percent 
discount rate of approximately $60,000-$2.1 million per year. Please 
see the complete RIA for a more detailed analysis of the costs and 
benefits of this proposed rule.

C. Executive Order 13771

    This proposed rule has been analyzed in accordance with Executive 
Order 13771 (``Reducing Regulation and Controlling Regulatory Costs'') 
and is likely to result in an E.O. 13771 deregulatory action, as it 
will result in cost savings (see above for discussion of the Benefits 
and Costs of Harmonization).

D. Executive Order 13132

    This proposed rule has been analyzed in accordance with the 
principles and criteria contained in Executive Order 13132 
(``Federalism''). It preempts State, local, and Indian tribe 
requirements, but does not propose any regulation that has substantial 
direct effects on the States, the relationship between the national 
government and the States, or the distribution of power and 
responsibilities among the various levels of government. Therefore, the 
consultation and funding requirements of Executive Order 13132 do not 
apply.
    The Federal hazmat law (49 U.S.C. 5101 et seq.) contains an express 
preemption provision (49 U.S.C. 5125(b)) that preempts State, local, 
and Indian tribe requirements on certain covered subjects, as follows:
    (1) The designation, description, and classification of hazardous 
material;
    (2) The packing, repacking, handling, labeling, marking, and 
placarding of hazardous material;
    (3) The preparation, execution, and use of shipping documents 
related to hazardous material and requirements related to the number, 
contents, and placement of those documents;
    (4) The written notification, recording, and reporting of the 
unintentional release in transportation of hazardous material; and
    (5) The design, manufacture, fabrication, inspection, marking, 
maintenance, recondition, repair, or testing of a packaging or 
container represented, marked, certified, or sold as qualified for use 
in transporting hazardous material in commerce.
    This proposed rule addresses covered subject items (1), (2), (3), 
(4), and (5) above and preempts State, local, and Indian tribe 
requirements not meeting the ``substantively the same'' standard. This 
proposed rule is necessary to incorporate changes adopted in 
international standards, effective January 1, 2019. If the proposed 
changes are not adopted in the HMR, U.S. companies--including numerous 
small entities competing in foreign markets--would be at an economic 
disadvantage because of their need to comply with a dual system of 
regulations. The changes in this proposed rulemaking are intended to 
avoid this result. Federal hazmat law provides at 49 U.S.C. 5125(b)(2) 
that, if DOT issues a regulation concerning any of the covered 
subjects, DOT must determine and publish in the Federal Register the 
effective date of Federal preemption. The effective date may not be 
earlier than the 90th day following the date of issuance of the final 
rule and not later than two years after the date of issuance. PHMSA 
proposes that the effective date of Federal preemption be 90 days from 
publication of a final rule in this matter.

[[Page 60999]]

E. Executive Order 13175

    This proposed rule was analyzed in accordance with the principles 
and criteria contained in Executive Order 13175 (``Consultation and 
Coordination with Indian Tribal Governments''). Because this proposed 
rule does not have tribal implications, and does not impose substantial 
direct compliance costs the funding and consultation requirements of 
Executive Order 13175 do not apply.

F. Regulatory Flexibility Act, Executive Order 13272, and DOT 
Procedures and Policies

    The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires an 
agency to review regulations to assess their impact on small entities, 
unless the agency determines that a rule is not expected to have a 
significant economic impact on a substantial number of small entities. 
This proposed rule facilitates the transportation of hazardous 
materials in international commerce by providing consistency with 
international standards. It applies to offerors and carriers of 
hazardous materials, some of whom are small entities, such as chemical 
manufacturers, users and suppliers, packaging manufacturers, 
distributors, and training companies. As previously discussed under 
``Executive Order 12866,'' the amendments in this proposed rule should 
result in net cost savings and ease the regulatory compliance burden 
for shippers engaged in domestic and international commerce, including 
trans-border shipments within North America.
    Many companies will realize economic benefits as a result of these 
amendments. Additionally, the changes effected by this NPRM will 
relieve U.S. companies, including small entities competing in foreign 
markets, from the burden of complying with a dual system of 
regulations. Therefore, PHMSA expects that these amendments will not, 
if promulgated, have a significant economic impact on a substantial 
number of small entities. However, PHMSA solicits comments on the 
anticipated economic impacts to small entities.
    This proposed rule has been developed in accordance with Executive 
Order 13272 (``Proper Consideration of Small Entities in Agency 
Rulemaking'') and 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.

G. Paperwork Reduction Act

    PHMSA is proposing to revise the approved information collections 
under the following Office of Management and Budget (OMB) Control 
Numbers: OMB Control No. 2137-0018, ``Inspection and Testing of 
Portable Tanks and Intermediate Bulk Containers;'' OMB Control No. 
2137-0034, ``Hazardous Materials Shipping Papers & Emergency Response 
Information;'' OMB Control No. 2137-0557, ``Approvals for Hazardous 
Materials;'' OMB Control No. 2137-0572, ``Testing Requirements for Non-
Bulk Packaging (Formerly: Testing Requirements for Packaging);'' OMB 
Control No. 2137-0559, ``Rail Carriers and Tank Car Tank Requirements, 
Rail Tank Car Tanks--Transportation of Hazardous Materials by Rail.''
OMB Control Number 2137-0018, ``Inspection and Testing of Portable 
Tanks and Intermediate Bulk Containers''
    PHMSA estimates this rulemaking will result in an increase in 
burden due to the proposed requirement to indicate the water 
temperature during a hydraulic pressure test for rigid plastics and 
composite IBCs. PHMSA does not estimate an increase in the number of 
respondents or responses, because the proposed amendment only adds 
burden for respondents already pressure testing rigid plastics and 
composite IBCs. PHMSA estimates that it will take an average of 1 
additional minute to add the additional information to the test report. 
This information collection, currently accounts for 20 respondents 
completing 100 test reports per year at 6 minutes per response. 
Increasing the burden time to 7 minutes per response increases the 
burden by 33 hours. At a mean hourly wage of $38.77, \16\ it is 
estimated to increase annual salary costs by $1,279.41. PHMSA does not 
anticipate this requirement to affect out-of-pocket expenses.

OMB Control Number 2137-0034, ``Hazardous Materials Shipping Papers & 
Emergency Response Information''
    PHMSA estimates that this NPRM will result in an overall increase 
in burden attributed to the proposed requirement to create a test 
summary for lithium cells and batteries manufactured after June 30, 
2003. As currently proposed, lithium cell or battery manufacturers will 
need to create a test summary for all of the previously manufactured 
lithium cells and batteries. Following the publication of the final 
rule, PHMSA will revise the annual burden, as a test summary will only 
need to be created following manufacture of a new lithium cell and 
battery. Because this NPRM accounts for previously manufactured lithium 
cells and batteries, PHMSA believes that the burden will substantially 
decrease for subsequent years after a final rule goes into effect.
    PHMSA identified 73 domestic lithium cell or battery manufacturers 
per U.S. Census' Annual Survey of Manufactures (ASM) (NAICS code 
335912).\17\ PHMSA looked at publicly available company websites for 35 
domestic companies known to manufacture lithium cells or batteries. Of 
the 35 domestic lithium cell or battery manufacturers websites that 
were reviewed, 14 provided product information (e.g. specification 
sheets or safety data sheets) for specific lithium cells or batteries 
the company currently manufactures or sells. Based on the information 
provided on these 14 company websites, the mean number of lithium cells 
and batteries currently manufactured by these domestic manufacturers is 
32. Based on the uncertainties noted below, PHMSA estimates that the 
number of batteries and cells currently manufactured--that were tested 
between June 30, 2003 and the estimated date of a final rule 
publication--by each domestic lithium cell or battery manufacture to be 
80 per manufacturer (32 lithium cells or batteries manufactured x 2.5). 
Therefore, 5,840 new test summaries must be created for lithium cells 
or batteries (73 manufacturers x 80 lithium cells or batteries).

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

    The time to create a test summary is estimated conservatively at 30 
minutes per document. PHMSA personnel obtained various existing test 
reports for lithium cells and batteries and

[[Page 61000]]

completed sample test summary documents utilizing these test reports 
with an average time to complete of 13 minutes. In these exercises, the 
test reports contained almost all the information required for 
completion of the test summary. PHMSA expects this to be the case for 
most test summaries and assumes that test reports will be readily 
available for most design types, but to account for the procuring of 
any missing information where required, we have estimated the test 
summary completion time to be 30 minutes. Therefore, PHMSA estimates 
that this proposal will increase burden by 2,920 hours (5,840 test 
reports x 30 minutes).
    To determine the projected salary cost for preparing new test 
summaries, PHMSA estimates a mean hourly wage rate of approximately 
$67.03 \18\ for a total of $195,721.76 in salary cost (2,920 burden 
hours x $67.03). PHMSA does not estimate any out-of-pocket expenses for 
the creation of the test summary.

compensation (i.e., benefits) based on the BLS Employer Costs for 
Employee Compensation Summary, which indicates that wages for 
civilian workers are 68.3 percent of total compensation (total wage 
= wage rate/wage % of total compensation).

Uncertainties
--Information on company websites generally only accounts for battery 
and cells that are currently actively offered for sale by the company. 
The proposed TS requirement would be applicable to all batteries and 
cells manufactured after June 30, 2003. Thus, the canvassing of 
domestic manufacturer websites does not account for these previously 
made cells and batteries.
--While several websites did show component cells for sale, others did 
not. It is difficult to know if some battery manufacturers that only 
list completed batteries on their websites also make their own cells.
--Canvassing searched 14 domestic lithium battery cell and battery 
manufacturers (out of an estimated 73). Companies that did not provide 
individual product listings were not included in our calculations. 
However, the companies that were researched do constitute a 
representative sample of lithium cell and battery manufacturers making 
cells and batteries for automobiles, military, medical, and portable 
electronic devices.

    Annual Increase in Number of Respondents: 73.
    Annual Increase in Number of Responses: 5,840.

    Annual Increase in Salary Costs: $195,721.76.
    Annual Increase in Burden Costs: $0.
    This test summary requirement is also anticipated to increase the 
burden for recordkeeping requirements. As detailed in the proposed 
requirements, the test summary must be made available, including to 
subsequent distributors, upon request. For the purposes of this 
analysis PHMSA assumes that in order to make a test summary available 
manufacturers and downstream distributors of lithium cells and 
batteries will likely choose the alternative that results in the least 
amount of recordkeeping burden possible. PHMSA believes this least 
burdensome method would be to provide links to battery manufacturer 
websites where the information will be made available. This assumption 
presumes that infrastructure such as website storage capacity and 
upkeep are available and existing costs for cell and battery 
manufacturers and distributors. Each of these actions requires one 
recordkeeping action per test summary for cell and battery 
manufacturers and one record for each link generated by downstream 
distributors.
    To attempt to quantify the burden hours and salary costs for this 
proposed recordkeeping requirement, PHMSA examined entities in NAICS 
codes for battery retailers, wholesalers, and merchants (NAICS 453998 & 
423610) and identified the percentage of entities in each NAICS 
industry that is involved in distributing batteries based on the sub-
NAICS product series information provided in the 2012 Economic Census 
by Industry. PHSMA multiplied this percent by the more recent, 2016 
County Business Patterns estimate of the total number of entities to 
estimate the number of potentially impacted respondents. Based on these 
calculations, PHMSA estimates that 5,644 downstream distributors of 
lithium cells and batteries comprised of product manufacturers and 
distributors/retailers, in addition to the 73 domestic manufacturers 
identified above could be subject to additional recordkeeping 
requirements as a result of this proposal. We further estimate that 
product manufacturers utilize cells and batteries from an average of 5 
different cell or battery manufacturers. Lastly, we estimate that 
distributors and retail outlets utilize cells and batteries from an 
average of 20 cell or battery manufacturers. See table 5 for a 
breakdown of the lithium cell and battery supply chain, the number of 
estimated entities, and the number of estimated test summaries that are 
required to be made available.

    PHMSA is also proposing additional requirements that would affect 
the burden for OMB Control No. 2137-0034, but PHMSA believes that the 
overall effect on the number of respondents and burden hours are 
negligible in relationship to the number of respondents and burden 
hours currently associated with this information collection. The 
requirements include proposing: To require ``TEMPERATURE CONTROLLED'' 
on a shipping paper if not already indicated in the proper shipping, 
when appropriate; to remove 1-dodecene to the list of marine pollutants 
in Appendix B to Sec.  172.101; to reduce the information required on a

materials transported by vessel.
OMB Control Number 2137-0557, ``Approvals for Hazardous Materials''
    We anticipate this NPRM will increase the overall burden for this

provision 347 to four entries on the HMT, which would require the 
articles to pass the 6(d) test from Part I of the UN Manual of Tests 
and Criteria to maintain Compatibility Group ``S'' classification. It 
is estimated that this will increase the number of annual respondents 
by 54. PHMSA estimates that each respondent will submit 10 applications 
each year, for a total increase of 540 annual responses (54 respondents 
x 10 responses). PHMSA estimates that each application will take 4.75 
hours to complete, for a total increase of 2,565 annual burden hours 
(2,500 response x 4.75 hours). At a mean hourly wage of $79.06,\20\ 
PHMSA estimates an increase of $202,797 in salary costs. PHMSA does not

    PHMSA is also proposing additional requirements that would affect 
the burden for OMB Control No. 2137-0557, but PHMSA believes that the 
overall effect on the number of respondents and burden hours are 
negligible in relationship to the number of respondents and burden 
hours associated with this OMB Control Number. PHMSA expects a minimal 
increase due to the proposed revision of special provision A105, which 
would allow a person to obtain approval from the Associate 
Administrator for Hazardous Materials Safety if the quantity of 
hazardous materials exceeds the quantity limits and applicability 
provisions of Sec.  173.222(c). PHMSA also expects a minimal decrease 
in the number of approval applicants based on the adoption of a new 
entry in the Sec.  173.224 Self-Reactive Materials Table and the 
adoption of three new entries in the Sec.  173.225 Organic Peroxide 
Table. Respondents wishing to offer these materials in transportation, 
are no longer required to obtain approval by the Associate 
Administrator for Hazardous Materials Safety.
OMB Control No. 2137-0572, ``Testing Requirements for Non-Bulk 
Packaging (Formerly: Testing Requirements for Packaging)''
    PHMSA estimates this rulemaking will result in an increase in 
burden due to the proposed requirement to include the water temperature 
during the hydraulic pressure test for plastic non-bulk packagings. 
PHMSA does not estimate an increase in the number of respondents or 
responses, because the proposed amendment only adds burden to persons 
currently pressure testing plastic non-bulk packagings. PHMSA currently 
estimates that 5,000 respondents create 3 test reports per year, and 
that each test report takes 2 hours to complete. Based on the estimated 
percentage of respondents who currently requalify plastic non-bulk 
packagings, PHMSA estimates that it will take an average of 1 minute to 
add the water temperature on the requalification report, for an 
estimated increase of 250 burden hours. At a mean hourly wage of 
$68.58,\21\ it is estimated to increase annual salary costs of $17,145. 
PHMSA does not anticipate this requirement to affect out-of-pocket 
expenses.

OMB Control No. 2137-0559 ``Rail Carrier and Tank Car Tank 
Requirements, Rail Tank Car Tanks--Transportation of Hazardous 
Materials by Rail''
    PHMSA anticipates this NPRM will result in a decrease in burden 
because of the proposed requirement to recognize Transport Canada 
issued Temporary Certificates for one time movements of non-compliant 
tank cars, in lieu of a DOT-issued OTMA when the tank car shipment's 
origin or destination is in Canada. Data from the FRA indicates that in 
calendar year 2017 there were 214 one time movement requests for tank 
car shipments with an origin or destination in Canada. PHMSA estimates 
that half of these movements will operate under a Temporary Certificate 
issued by Transport Canada, and thus not require PHMSA approval. 
Therefore, PHMSA estimates there will be a decrease in 54 annual 
respondents. Each of these respondents is estimated to annually request 
two OTMAs, for a decrease of 108 responses. PHMSA estimates that each 
application requires 4.75 hours to complete, resulting in a reduction 
of 513 burden hours. At an estimated mean hourly wage of $68.58,\22\ 
this reduction is expected to save $35,181.54 in salary cost. PHMSA

H. Regulation Identifier Number (RIN)

    A regulation identifier number (RIN) is assigned to each regulatory 
action listed in the Unified Agenda of Federal Regulations. The 
Regulatory Information Service Center publishes the Unified Agenda in 
April and October of each year. The RIN contained in the heading of 
this document can be used to cross-reference this action with the 
Unified Agenda.

I. Unfunded Mandates Reform Act of 1995

    This proposed rule does not impose unfunded mandates under the 
Unfunded Mandates Reform Act of 1995. It does not result in costs of 
$160.8 million or more, adjusted for inflation, to either State, local, 
or tribal governments, in the aggregate, or to the private sector in 
any one year, and is the least burdensome alternative that achieves the 
objective of the rule.

J. Environmental Assessment

    The National Environmental Policy Act of 1969, 42 U.S.C. 4321-4375, 
requires that Federal agencies analyze proposed actions to determine 
whether the action will have a significant impact on the human 
environment. The Council on Environmental Quality (CEQ) regulations 
that implement NEPA (40 CFR parts 1500-1508) require Federal agencies 
to conduct an environmental review considering (1) the need for the 
proposed action, (2) alternatives to the proposed action, (3) probable 
environmental impacts of the proposed action and alternatives, and (4) 
the agencies and persons consulted during the consideration process.
1. Purpose and Need
    This NPRM would amend the HMR (49 CFR parts 171-180) to maintain 
alignment with international standards by incorporating the 20th 
Revised Edition of the UN Model Regulations, Amendment 39-18 to the 
IMDG Code, the 2019-2020 ICAO Technical Instructions, and Transport 
Canada's newest amendments to TDG Regulations.
    This action is necessary to incorporate changes adopted in the IMDG 
Code, the ICAO Technical Instructions, and the UN Model Regulations, 
effective January 1, 2019. If the changes in this proposed rule are not 
adopted in the HMR by this effective date, U.S. companies--including 
numerous small entities competing in foreign markets--would be at an 
economic disadvantage because of their need to comply with a dual 
system of regulations. The changes in this proposed rulemaking are 
intended to avoid this result.
    The intended effect of this action is to align the HMR with 
international transport standards and requirements to the extent 
practicable in accordance with Federal hazmat law (see 49 U.S.C. 5120). 
When considering the adoption of international standards under the HMR, 
PHMSA reviews and evaluates each amendment on its own merit, on its 
overall impact on transportation safety, and on the economic 
implications associated with its adoption. Our goal is to harmonize 
internationally without diminishing the level of safety currently 
provided by the HMR or imposing undue burdens on the regulated public. 
PHMSA has provided a brief summary of each revision and the 
justification for the revision.
2. Alternatives
    In proposing this rulemaking, PHMSA is considering the following 
alternatives:
No Action Alternative
    If PHMSA were to select the No Action Alternative, current 
regulations would remain in place and no new provisions would be added.
Preferred Alternative
    This alternative is the current proposal as it appears in this 
NPRM, applying to transport of hazardous materials by various transport 
modes (highway, rail, vessel, and aircraft). The proposed amendments 
included in this alternative are more fully addressed in the preamble 
and regulatory text sections of this NPRM. However, they generally 
include:
    (1) Updated references to various international hazardous materials 
transport standards;
    (2) Amendments to the Hazardous Materials Table to include twelve 
new N.O.S. entries for articles containing dangerous goods, as well as 
additional defining criteria, authorized packagings, and safety 
requirements for transportation of these articles;
    (3) Amendments to add, revise, or remove certain proper shipping 
names, packing groups, special provisions, packaging authorizations, 
bulk packaging requirements, and vessel stowage requirements. 
Additionally, changes throughout the packaging requirements in part 173 
to authorize more flexibility when choosing packages for hazardous 
materials;
    (4) Changes to the corrosivity classification procedures to include 
methods that do not involve testing for making a corrosivity 
classification determination for mixtures;
    (5) The creation of a lithium cell or battery test summary; and
    (6) Amendments to the HMR regarding the segregation of lithium 
cells and batteries offered for transport or transported on aircraft in 
relation to other hazardous materials.
3. Probable Environmental Impact of the Alternatives
No Action Alternative
    If PHMSA were to select the No Action Alternative, current 
regulations would remain in place and no new provisions would be added. 
However, efficiencies gained through harmonization with updates to 
international transport standards--

[[Page 61003]]

including regulated substances, definitions, packagings, stowage 
requirements/codes, flexibilities allowed, enhanced markings, 
segregation requirements, etc.--would not be realized.
    Additionally, the No Action Alternative would not adopt enhanced 
and clarified regulatory requirements, which are intended to decrease 
the risk of environmental and safety incidents. For example, updates to 
corrosivity classification requirements are intended to better ensure 
that hazardous materials in this hazard class are properly identified. 
The lithium battery test summary and the lithium battery segregation 
requirements are intended to provide added protections against the 
risks that lithium batteries pose to air transportation. Also, the 
vessel stowage requirements seek to better separate materials that may 
be reactive to reduce the risks of serious incidents. While these are 
only a few examples, the provisions proposed in this Notice have been 
developed and vetted by the U.S. and international experts responsible 
for the following hazardous materials standards: UN Model Regulations, 
ICAO Technical Instructions, IMDG Code, and the Transport Canada TDG 
Regulations. Not adopting the proposed environmental and safety 
requirements in the NPRM under the No Action Alternative would result 
in a lost opportunity for reducing environmental and safety-related 
incidents.
    Greenhouse gas emissions would remain relatively the same under the 
No Action Alternative. However, it is expected that fewer incidents 
result in fewer emissions of greenhouse gases and other pollutants.
Preferred Alternative
    If PHMSA selects the provisions as proposed in this NPRM, we 
believe that safety and environmental risks would be reduced and that 
protections to human health and environmental resources would be 
increased. Potential environmental impacts of each proposed amendment 
in the preferred alternative are discussed as follows:
    1. Incorporation by Reference: PHMSA proposes to update references 
to various international hazardous materials transport standards 
including the 2019-2020 ICAO Technical Instructions; Amendment 39-18 to 
the IMDG Code; the 20th Revised Edition of the UN Model Regulations; 
amendment 1 to the 6th Revised Edition of the UN Manual of Tests and 
Criteria; and the latest amendments to the Transport Canada TDG 
Regulations. Additionally, we propose to add three new references to 
standards and update six other references to standards applicable to 
the manufacture use and requalification of pressure vessels published 
by the International Organization for Standardization.
    PHMSA believes that this proposed amendment, which will increase 
standardization and consistency of regulations, will result in greater 
protection of human health and the environment. Consistency between 
U.S. and international regulations enhances the safety and 
environmental protection of international hazardous materials 
transportation through better understanding of the regulations, an 
increased level of industry compliance, the smooth flow of hazardous 
materials from their points of origin to their points of destination, 
and consistent emergency response procedures in the event of a 
hazardous materials incident. The HMR authorize shipments prepared in 
accordance with the ICAO Technical Instructions from transport by 
aircraft and for transport by motor vehicle either before or after 
being transported by aircraft. Similarly, the HMR authorize shipments 
prepared in accordance with the IMDG Code if all or part of the 
transportation is by vessel. The authorizations to use the ICAO 
Technical Instructions and the IMDG Code are subject to certain 
conditions and limitations outlined in part 171 subpart C.
    Harmonization will result in more targeted and effective training, 
thereby facilitating enhanced environmental protection. This proposed 
amendment will eliminate inconsistent hazardous materials regulations, 
which hamper compliance training efforts. For ease of compliance with 
appropriate regulations, air and vessel carriers engaged in the 
transportation of hazardous materials generally elect to comply with 
the ICAO Technical Instructions and IMDG Code, as appropriate.
    Greenhouse gas emissions would remain the same under this proposed 
amendment.
    2. Consistent with amendments adopted into the UN Model 
Regulations, PHMSA proposes to revise the Hazardous Materials Table in 
Sec.  172.101 to include 12 new N.O.S. entries for articles containing 
dangerous goods and to add into the HMR defining criteria, authorized 
packagings, and safety requirements for transportation of these 
articles. Inclusion of entries in the HMT reflects a degree of danger 
associated with a particular material and identifies appropriate 
packaging intended to reduce the likelihood of release of hazardous 
materials that threaten human health and safety and the environment. 
This proposed change provides a level of protection and consistency for 
all articles specifically listed in the HMT, without diminishing 
environmental protection and safety.
    Greenhouse gas emissions would remain the same under this proposed 
amendment.
    3. PHMSA proposes amendments to the HMT to add, revise, or remove 
certain proper shipping names, packing groups, special provisions, 
packaging authorizations, bulk packaging requirements, and vessel 
stowage requirements. Amendments to HMT proper shipping names include: 
requiring additional 6(d) testing for certain explosive articles; 
adding an entry for ``Lithium batteries installed in cargo transport 
unit''; and adding two new entries for ``Toxic solid, flammable, 
inorganic, n.o.s.'' Additionally, we also propose to add and revise 
special provisions, large packaging authorizations, and intermediate 
bulk container (IBC) authorizations consistent with the UN Model 
Regulations to provide a wider range of packaging options to shippers 
of hazardous materials.
    Inclusion of entries in the HMT reflects a degree of danger 
associated with a particular material and identifies appropriate 
packaging. These proposed inclusions in the HMT provide a greater level 
of protection against release and consistency across borders.
    4. Changes to the corrosivity classification procedures to include 
methods that do not involve testing for making a corrosivity 
classification determination for mixtures.
    PHMSA believes that this proposed amendment permits additional 
flexibility for classifying corrosive mixtures and allows offerors the 
ability to make a classification and packing group assignment without 
having to conduct physical tests. This allowance does not compromise 
environmental protection or safety. Increased use of not-test methods 
for classification of mixtures results in less product being utilized 
to conduct physical testing, less clean-up and disposal that occurs 
after testing, which provide environmental benefits along with expanded 
alternatives to traditional testing methods.
    5. Consistent with amendments adopted into the UN Model 
Regulations, PHMSA proposes to require the creation of a lithium cell 
or battery test summary.
    PHMSA believes that these proposed amendments provide important 
additional information to downstream shippers and consumers of lithium 
batteries, including a standardized set of

[[Page 61004]]

elements that provide traceability and accountability that lithium 
cells and batteries offered for transport meet the appropriate UN 
design tests. Testing standards for lithium batteries help ensure 
design types are subject to as many as eight separate tests designed to 
assess their ability to withstand the anticipated rigors incurred 
during transport. Increased availability of documentation indicating 
that cells and batteries are of a tested type could lead to a decrease 
in the number of illegitimate lithium batteries that can present a 
hazard to users and the environment.
    6. Amendments to the HMR regarding the segregation of lithium cells 
and batteries offered for transport or transported on aircraft in 
relation to other hazardous materials.
    PHMSA believes that the proposed amendments requiring lithium 
batteries to be segregated from other listed dangerous goods would 
enhance safety and environmental protection by decreasing the risk 
posed by a fire involving lithium batteries or another dangerous good. 
The segregation requirements are intended to avoid the cumulative 
effects of a fire involving both goods simultaneously. PHMSA believes 
that this proposed amendment would provide for a net increase in 
environmental protection and safety by potentially lessening the 
severity of a fire aboard an aircraft, thus preventing release and 
damage to human health and the natural environment.
Summary
    In summary, consistency between these international regulations and 
the HMR allows shippers and carriers to train their hazmat employees in 
a single set of requirements for classification, packaging, hazard 
communication, handling, stowage, etc., thereby minimizing the 
possibility of improperly preparing and transporting a shipment of 
hazardous materials because of differences between domestic and 
international regulations. These proposed changes mirror changes in the 
Dangerous Goods List of the 20th Revised Edition of the UN Model 
Regulations, the 2019-2020 ICAO Technical Instructions, and Amendment 
39-18 to the IMDG Code. It is extremely important for the domestic HMR 
to mirror these international standards regarding the entries in the 
HMT to ensure consistent naming conventions across modes and 
international borders.
    In some instances, the proposed changes in this Notice may result 
in a streamlining or reduction in burden to industry. However, in each 
case, PHMSA believes that those changes are consistent with safety and 
will not significantly increase the risk of release. Most of the 
proposed regulations in this Notice increase protections aimed at 
avoiding safety and environmental risks.
    Greenhouse gas emissions would not significantly increase under 
this proposed amendment, but fewer incidents are expected to result in 
fewer emissions of greenhouse gases and other pollutants.
4. Agencies Consulted
    This NPRM represents PHMSA's first action in the U.S. for this 
program area. PHMSA has coordinated with the U.S. Federal Aviation 
Administration, the Federal Motor Carrier Safety Administration, the 
Federal Railroad Administration, and the U.S. Coast Guard, in the 
development of this proposed rule. PHMSA will consider the views 
expressed in comments to the NPRM submitted by members of the public, 
state and local governments, and industry.
5. Conclusion
    The provisions of this proposed rule build on current regulatory 
requirements in order to enhance the transportation safety and security 
of shipments of hazardous materials transported by highway, rail, 
aircraft, and vessel, thereby reducing the risks of an accidental or 
intentional release of hazardous materials and consequent environmental 
damage. PHMSA proposes to find that the net environmental impact of 
this proposal will be positive and that there are no significant 
environmental impacts associated with this proposed rule. PHMSA 
welcomes any views, data, or information related to environmental 
impacts that may result if the proposed requirements are adopted, as 
well as the ``no action alternative'' and other viable alternatives and 
their environmental impacts.

L. Executive Order 13609 and International Trade Analysis

    Under Executive Order 13609 (``Promoting International Regulatory 
Cooperation''), 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.
    Similarly, the Trade Agreements Act of 1979 (Pub. L. 96-39), as 
amended by the Uruguay Round Agreements Act (Pub. L. 103-465), 
prohibits Federal agencies from establishing any standards or engaging 
in related activities that create unnecessary obstacles to the foreign 
commerce of the United States. For purposes of these requirements, 
Federal agencies may participate in the establishment of international 
standards, so long as the standards have a legitimate domestic 
objective, such as providing for safety, and do not operate to exclude 
imports that meet this objective. The statute also requires 
consideration of international standards and, where appropriate, that 
they be the basis for U.S. standards.
    PHMSA participates in the establishment of international standards 
to protect the safety of the American public, and it has assessed the 
effects of the proposed rule to ensure that it does not cause 
unnecessary obstacles to foreign trade. In fact, the rule is designed 
to facilitate international trade. Accordingly, this rulemaking is 
consistent with Executive Order 13609 and PHMSA's obligations under the 
Trade Agreement Act, as amended.

M. National Technology Transfer and Advancement Act

    The National Technology Transfer and Advancement Act of 1995 (15 
U.S.C. 272 note) directs Federal agencies to use voluntary consensus 
standards in their regulatory activities unless doing so would be 
inconsistent with applicable law or otherwise impractical. Voluntary 
consensus standards are technical standards (e.g., specification of 
materials, test methods, or performance requirements) that are 
developed or adopted by voluntary

[[Page 61005]]

consensus standard bodies. This NPRM involves multiple voluntary 
consensus standards which are discussed at length in the discussion on 
Sec.  171.7.

    387 When materials are stabilized by temperature control, the 
provisions of Sec.  173.21(f) of this subchapter apply. When chemical 
stabilization is employed, the person offering the material for 
transport shall ensure that the level of stabilization is sufficient to 
prevent the material as packaged from dangerous polymerization at 50 
[deg]C (122 [deg]F). If chemical stabilization becomes ineffective at 
lower temperatures within the anticipated duration of transport, 
temperature control is required and is forbidden by aircraft. In making 
this determination factors to be taken into consideration include, but 
are not limited to, the capacity and geometry of the packaging and the 
effect of any insulation present, the temperature of the material when 
offered for transport, the duration of the journey, and the ambient 
temperature conditions typically encountered in the journey 
(considering also the season of year), the effectiveness and other 
properties of the stabilizer employed, applicable operational controls 
imposed by regulation (e.g. requirements to protect from sources of 
heat, including other cargo carried at a temperature above ambient) and 
any other relevant factors. The provisions of this special provision 
will be effective until January 2, 2021, unless we terminate them 
earlier or extend them beyond that date by notice of a final rule in 
the Federal Register.

22. Section 173.137 is revised to read as follows:


Sec.  173.137   Class 8--Assignment of packing group.

    The packing group of a Class 8 material is indicated in Column 5 of 
the Sec.  172.101 Table. When the Sec.  172.101 Table provides more 
than one packing group for a Class 8 material, the packing group must 
be determined using data obtained from tests conducted in accordance 
with the OECD Guidelines for the Testing of Chemicals, Number 435, ``In 
Vitro Membrane Barrier Test Method for Skin Corrosion'' (IBR, see Sec.  
171.7 of this subchapter) or Number 404, ``Acute Dermal Irritation/
Corrosion'' (IBR, see Sec.  171.7 of this subchapter). A material that 
is determined not to be corrosive in accordance with OECD Guideline for 
the Testing of Chemicals, Number 430, ``In Vitro Skin Corrosion: 
Transcutaneous Electrical Resistance Test (TER)'' (IBR, see Sec.  171.7 
of this subchapter) or Number 431, ``In Vitro Skin Corrosion: 
Reconstructed Human Epidermis (RHE) Test Method'' (IBR, see Sec.  171.7 
of this subchapter) may be considered not to be corrosive to human skin 
for the purposes of this subchapter without further testing. However, a 
material determined to be corrosive in accordance with Number 430 or 
Number 431 must be further tested using Number 435 or Number 404. The 
packing group assignment using data obtained from tests conducted in 
accordance with OECD Guideline Number 404 or Number 435 must be as 
follows:
    (a) Packing Group I. Materials that cause irreversible damage to 
intact skin tissue within an observation period of up to 60 minutes, 
starting after the exposure time of three minutes or less.
    (b) Packing Group II. Materials, other than those meeting Packing 
Group I, criteria that cause irreversible damage to intact skin tissue 
within an observation period of up to 14 days, starting after the 
exposure time of more than three minutes but not more than 60 minutes.

[[Page 61050]]

    (c) Packing Group III. Materials, other than those meeting Packing 
Group I or II criteria--
    (1) That cause irreversible damage to intact skin tissue within an 
observation period of up to 14 days, starting after the exposure time 
of more than 60 minutes but not more than 4 hours; or
    (2) That do not cause irreversible damage to intact skin tissue but 
exhibit a corrosion on either steel or aluminum surfaces exceeding 6.25 
mm (0.25 inch) a year at a test temperature of 55 [deg]C (130 [deg]F) 
when tested on both materials. The corrosion may be determined in 
accordance with the UN Manual of Tests and Criteria (IBR, see Sec.  
171.7 of this subchapter) or other equivalent test methods.
    (d) Alternative packing group assignment methods for mixtures. For 
mixtures it is necessary to obtain or derive information that allows 
the criteria to be applied to the mixture for the purpose of 
classification and assignment of packing groups. The approach to 
classification and assignment of packing groups is tiered, and is 
dependent upon the amount of information available for the mixture 
itself, for similar mixtures and/or for its ingredients. The flow chart 
in Figure 1 to paragraph (d) outlines the process to be followed:
[GRAPHIC] [TIFF OMITTED] TP27NO18.000

    (1) Bridging principles. Where a mixture has not been tested to 
determine its skin corrosion potential, but there is sufficient data on 
both the individual ingredients and similar tested mixtures to 
adequately classify and assign a packing group for the mixture, this 
data will be used in accordance with the following bridging principles. 
This ensures that the classification process uses the available data to 
the greatest extent possible in characterizing the hazards of the 
mixture.
    (i) Dilution. If a tested mixture is diluted with a diluent which 
does not meet the criteria for Class 8 and does not affect the packing 
group of other ingredients, then the new diluted mixture may be 
assigned to the same packing group as the original tested mixture. In 
certain cases, diluting a mixture or substance may lead to an increase 
in the corrosive properties. If this is the case, this bridging 
principle cannot be used.
    (ii) Batching. The skin corrosion potential of a tested production 
batch of a mixture can be assumed to be substantially equivalent to 
that of another untested production batch of the same commercial 
product when produced by or under the control of the same manufacturer, 
unless there is reason to believe there is significant variation such 
that the skin corrosion potential of the untested batch has changed. If 
the latter occurs, a new classification is necessary.
    (iii) Concentration of mixtures of packing group I. If a tested 
mixture meeting the criteria for inclusion in packing group I is 
concentrated, the more concentrated untested mixture may be assigned to 
packing group I without additional testing.
    (iv) Interpolation within one packing group. For three mixtures (A, 
B and C) with identical ingredients, where mixtures A and B have been 
tested and are in the same skin corrosion packing group, and where 
untested mixture C has the same Class 8 ingredients as mixtures A and B 
but has concentrations of Class 8 ingredients intermediate to the 
concentrations in mixtures A and B, then mixture C is assumed to be in 
the same skin corrosion packing group as A and B.
    (v) Substantially similar mixtures. Given the following:
    (A) Two mixtures: (A+B) and (C+B);
    (B) The concentration of ingredient B is the same in both mixtures;
    (C) The concentration of ingredient A in mixture (A+B) equals the 
concentration of ingredient C in mixture (C+B);
    (D) Data on skin corrosion for ingredients A and C are available 
and substantially equivalent, i.e. they are the same skin corrosion 
packing group and do not affect the skin corrosion potential of B.
    (E) If the above mixture (A+B) or (C+B) is already classified based 
on test data, then the other mixture may be assigned to the same 
packing group.
    (2) Calculation method based on the classification of the 
substances. (i) Where a mixture has not been tested to determine its 
skin corrosion potential, nor is sufficient data available on similar 
mixtures, the corrosive properties of the substances in the mixture 
shall be considered to classify and assign a packing group. Applying 
the calculation method is only allowed if there are no synergistic 
effects that make the mixture more corrosive than the sum of its 
substances. This restriction applies only if packing group

[[Page 61051]]

II or III would be assigned to the mixture.
    (A) All Class 8 ingredients present at a concentration of >=1% 
shall be taken into account, or <1% if these ingredients are still 
relevant for classifying the mixture to be corrosive to skin.
    (B) When a specific concentration limit (SCL) is assigned to a 
substance following its entry in the Hazardous Materials Table or in a 
special provision, this limit shall be used instead of the generic 
concentration limits (GCL). This appears where 1% is used in the first 
step for the assessment of the packing group I substances, and where 5% 
is used for the other steps respectively in Appendix I of this part.
    (C) The following formula must be used for each step of the 
calculation process. The criterion for a packing group is fulfilled 
when the result of the calculation is >=1. The generic concentration 
limits to be used for the evaluation in each step of the calculation 
method are those found in Appendix I of this part. Where applicable, 
the generic concentration limit shall be substituted by the specific 
concentration limit assigned to the substance(s) (SCLi), and the 
adapted formula is a weighted average of the different concentration 
limits assigned to the different substances in the mixture:
[GRAPHIC] [TIFF OMITTED] TP27NO18.001

PG xi = concentration of substance 1, 2 . . . i in the mixture, 
assigned to packing group x (I, II or III)
GCL = generic concentration limit
SCLi = specific concentration limit assigned to substance i

    Note to Sec.  173.137: When an initial test on either a steel or 
aluminum surface indicates the material being tested is corrosive, 
the follow up test on the other surface is not required.

test data are not available, and which are to be transported for 
further testing or product evaluation, may be assigned an appropriate 
shipping description for Self-reactive materials Type C, packaged and 
offered for transportation under the following conditions:

[[Page 61058]]

    (i) Data available to the person offering the material for 
transportation must indicate that the sample would pose a level of 
hazard no greater than that of a self-reactive material Type B and that 
the control temperature, if any, is sufficiently low to prevent any 
dangerous decomposition and sufficiently high to prevent any dangerous 
phase separation;
    (ii) The sample must be packaged in accordance with packing method 
OP2;
    (iii) Packages of the self-reactive material may be offered for 
transportation and transported in a quantity not to exceed 10 kg (22 
pounds) per transport vehicle; and
    (iv) One of the following shipping descriptions must be assigned:

organic substances carrying functional groups listed in tables A6.1 
and/or A6.2 in Annex 6 (Screening Procedures) of the UN Manual of Tests 
and Criteria (IBR, see Sec.  171.7 of this subchapter) may be 
transported under UN 3224 or UN 3223, as applicable, of Division 4.1 
provided that:
    (i) The samples do not contain any:
    (A) Known explosives;
    (B) Substances showing explosive effects in testing;
    (C) Compounds designed with the view of producing a practical 
explosive or pyrotechnic effect;
    (D) Components consisting of synthetic precursors of intentional 
explosives;
    (ii) For mixtures, complexes or salts of inorganic oxidizing 
substances of Division 5.1 with organic material(s), the concentration 
of the inorganic oxidizing substance is:
    (A) Less than 15%, by mass, if assigned to packing group I or II; 
or
    (B) Less than 30%, by mass, if assigned to packing group III;
    (iii) Available data does not allow a more precise classification;
    (iv) The sample is not packed together with other goods;
    (v) Must be packaged as follows:
    (A) The quantity per individual inner cavity does not exceed 0.01 g 
for solids or 0.01 mL for liquids and the maximum net quantity per 
outer packaging does not exceed 20 g for solids or 20 mL for liquids, 
or in the case of mixed packing the sum of grams and mL does not exceed 
20:
    (1) The samples are carried in microtiter plates or multi-titer 
plates made of plastics, glass, porcelain or stoneware as an inner 
packaging;
    (2) only combination packaging with outer packaging comprising 
boxes (4A, 4B, 4N, 4C1, 4C2, 4D, 4F, 4G, 4H1 and 4H2) are permitted; or
    (B) The maximum content of each inner packaging does not exceed 1 g 
for solids or 1 mL for liquids and the maximum net quantity per outer 
packaging does not exceed 56 g for solids or 56 mL for liquids, or in 
the case of mixed packing the sum of grams and mL does not exceed 56:
    (1) The individual substance is contained in an inner packaging of 
glass or plastics of maximum capacity of 30 mL placed in an expandable 
polyethylene foam matrix of at least 130 mm thickness having a density 
of 18 1 g/L;
    (2) Within the foam carrier, inner packagings are segregated from 
each other by a minimum distance of 40 mm and from the wall of the 
outer packaging by a minimum distance of 70 mm. The package may contain 
up to two layers of such foam matrices, each carrying up to twenty-
eight inner packagings;
    (3) The outer packaging consists only of corrugated fibreboard 
boxes (4G) having minimum dimensions of 60 cm (length) by 40.5 cm 
(width) by 30 cm (height) and minimum wall thickness of 1.3 cm.
    (vi) When dry ice or liquid nitrogen is optionally used as a 
coolant for quality control measures, all applicable requirements of 
this subchapter must be met. Interior supports must be provided to 
secure the inner packagings in the original position after the ice or 
dry ice has dissipated. If ice is used, the outside packaging or 
overpack must be leakproof. If dry ice is used, the requirements in 
Sec.  173.217 must be met. The inner and outer packagings must maintain 
their integrity at the temperature of the refrigerant used as well as 
the temperatures and the pressures which could result if refrigeration 
were lost.

28. Section 173.232 is added to subpart E to read as follows:


Sec.  173.232   Articles containing hazardous materials, n.o.s.

    (a) Articles containing hazardous materials may be classified as 
otherwise provided by this subchapter under the proper shipping name 
for the hazardous materials they contain or in accordance with this 
section. For the purposes of this section, ``article'' means machinery, 
apparatus, or other devices containing one or more hazardous materials 
(or residues thereof) that are an integral element of the article, 
necessary for its functioning, and that cannot be removed for the 
purpose of transport. An inner packaging is not an article. For 
articles that do not have an existing proper shipping name and that 
contain only hazardous materials within the permitted limited quantity 
amounts specified in column (8A) of the Sec.  172.101 Table, see 
UN3363, Dangerous goods in machinery or apparatus, as prescribed in 
Sec.  172.102(c)(1), Special provision 136, and Sec.  173.222.
    (b) Such articles may contain batteries. Lithium batteries that are 
integral to the article must be of a type proven to meet the testing 
requirements of the UN Manual of Tests and Criteria, Part III, 
subsection 38.3 (IBR, see Sec.  171.7 of this subchapter), except when 
otherwise specified by this subchapter.
    (c) This section does not apply to articles for which a more 
specific proper shipping name already exists in the Sec.  172.101 
Table. This section does not apply to hazardous materials of Class 1, 
Division 6.2, Class 7, or radioactive material contained in articles.
    (d) Articles containing hazardous materials must be assigned to the 
appropriate class or division determined by the hazards present using, 
where applicable, the precedence criteria prescribed in Sec.  173.2a 
for each of the hazardous materials contained in the article. If 
hazardous materials classified as Class 9 are contained within the 
article, all other hazardous materials present in the article must be 
considered to present a higher hazard.
    (e) Subsidiary hazards must be representative of the primary hazard 
posed by the other hazardous materials contained within the article. 
When only one item of hazardous materials is present in the article, 
the subsidiary hazard(s), if any, is the subsidiary hazard(s) 
identified in column 6 of the Sec.  172.101 Table. If the article 
contains more than one item of hazardous materials and these could 
react dangerously with one another during transport, each of the 
hazardous materials must be enclosed separately.
    (f)(1) Packagings must conform to the Packing Group II performance

    (2) No pressure receptacle due for requalification may be filled 
with a hazardous material and offered for transportation in commerce 
unless that pressure receptacle has been successfully requalified and 
marked in accordance with this subpart. A pressure receptacle may be 
requalified at any time during or before the month and year that the 
requalification is due. However, a pressure receptacle filled before 
the requalification becomes due may remain in service until it is 
emptied. In accordance with the Transport Canada TDG Regulations (IBR, 
see Sec.  171.7) a CAN marked UN cylinder may be requalified in the 
United States by a domestic requalifier, provided the requirements in 
Sec. Sec.  178.69, 178.70, and 178.71, as applicable, are met.

accordance with ISO 6406:2005(E) (IBR, see Sec.  171.7 of this 
subchapter). However, UN cylinders with a tensile strength greater than 
or equal to 950 MPa must be requalified by ultrasonic examination in 
accordance with ISO 6406:2005(E). For seamless steel cylinders and 
tubes, the internal inspection and hydraulic pressure test may be 
replaced by a procedure conforming to ISO 16148:2016(E) (IBR, see Sec.  
171.1).
