I. Executive Summary

    The Pipeline and Hazardous Materials Safety Administration (PHMSA) 
is amending 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 PHMSA's ongoing biennial process to harmonize the HMR with 
international regulations and standards.
    As part of this biennial process, PHMSA is amending the HMR to 
incorporate changes from the 20th Revised Edition of the UN Model 
Regulations, Amendment 39-18 of the International Maritime Dangerous 
Goods (IMDG) Code, and the 2019-2020 International Civil Aviation 
Organization (ICAO) Technical Instructions, which became effective 
January 1, 2019.\1\ Notable amendments to the HMR in this final rule 
include the following:
---------------------------------------------------------------------------

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

     Incorporation by Reference: PHMSA incorporates 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 are updating our incorporation by reference of the 
Transport Canada, Transportation of Dangerous Goods (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, PHMSA is adopting various updated International Organization 
for Standardization (ISO) standards.
     Hazardous Materials Table: PHMSA amends the Hazardous 
Materials Table (HMT; Sec.  172.101) consistent with recent changes in 
the Dangerous Goods List of the UN Model Regulations, the IMDG Code, 
and the ICAO Technical Instructions. Specifically, PHMSA is making 
amendments to the HMT to add, revise, or remove certain proper shipping 
names, hazard classes, packing groups, special provisions, packaging 
authorizations, bulk packaging requirements, and passenger and cargo 
aircraft maximum quantity limits.
     Articles Containing Dangerous Goods: PHMSA adds a 
classification system for articles containing hazardous materials that 
do not already have a proper shipping name. This addresses situations 
in which hazardous materials or hazardous materials residues are 
present in articles, and authorizes a safe method to transport articles 
that may be too large to fit into typical packages.
     Lithium Battery Test Summary: PHMSA adds requirements 
regarding lithium battery test summaries. The HMR requires lithium 
battery manufacturers to subject lithium batteries and cells to 
appropriate UN design tests to ensure they are classified correctly for 
transport, and to develop records of successful test completion, called 
a test report. The test summary includes a standardized set of elements 
that provide traceability and accountability, thereby ensuring that 
lithium cell and battery designs offered for transport contain specific 
information on the required UN tests. The test summary must be made 
available to subsequent distributors.
     Baggage Equipped with Lithium Batteries: PHMSA is amending 
the aircraft passenger provisions for carriage

[[Page 27811]]

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 will be required 
to be carried in the cabin of the aircraft unless the battery or 
batteries are removed. This restriction in checked baggage does 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 (Wh) rating not exceeding 2.7 Wh.
     Segregation of Lithium Batteries from Specific Hazardous 
Materials: PHMSA is adding 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 to implement a National Transportation Safety Board 
(NTSB) Safety Recommendation (A-16-001) 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 the flammable materials and lithium ion 
batteries that were loaded together in either the same or adjacent 
pallets as a contributing factor to the accident.
     Alternative Criteria for Classification of Corrosive 
Materials: PHMSA is including non-testing alternatives for classifying 
corrosive mixtures using existing data on its chemical properties. 
Currently, the HMR require offerors to classify Class 8 corrosive 
material and assign a packing group based on test data. The HMR 
authorizes 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. The alternatives added in this final rule 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 extending 
the sunset dates for provisions concerning the transportation of 
polymerizing substances from January 2, 2019 to January 2, 2023. This 
additional time will allow PHMSA to conduct research and analyze 
comments and data concerning the issue submitted to the docket for this 
rulemaking, to have a more comprehensive understanding of polymerizing 
substances and further consider the most appropriate transport 
provisions for these materials.

II. Background

    Federal hazardous materials transportation law (Federal hazmat law; 
49 U.S.C. 5101 et seq.) directs PHMSA to participate in relevant 
international standard-setting bodies and promotes consistency of the 
HMR with international transport standards to the extent practicable. 
Federal hazmat law permits PHMSA to depart from international standards 
where a more stringent standard or requirement is necessary in the 
public interest or if a different standard or requirement is 
unnecessary or unsafe. However, Federal hazmat law otherwise encourages 
domestic and international harmonization (see 49 U.S.C. 5120).
    Harmonization facilitates international trade by minimizing the 
costs and other burdens of complying with multiple or inconsistent 
safety requirements for transportation of hazardous materials. Safety 
is enhanced by creating a uniform framework for compliance. As the 
volume of hazardous materials transported in international commerce 
continues to grow, harmonization is increasingly important.
    PHMSA published a notice of proposed rulemaking (NPRM) under Docket 
HM-215O [83 FR 60970 (November 27, 2018)] to incorporate various 
amendments to harmonize the HMR with recent changes to the IMDG Code, 
ICAO Technical Instructions, and the United Nations Recommendations on 
the Transport of Dangerous Goods--Model Regulations (UN Model 
Regulations). When considering alignment of the HMR with international 
standards, PHMSA reviews and evaluates each amendment on its own merit, 
on the basis of its overall impact on transportation safety, and on the 
basis of the economic implications associated with its adoption into 
the HMR. PHMSA's goal is to harmonize without diminishing the level of 
safety currently provided by the HMR or imposing undue burdens on the 
regulated community.

III. Incorporation by Reference Discussion Under 1 CFR Part 51

    The UN Model Regulations, Manual of Tests and Criteria, and GHS, 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 either print or electronic versions 
through the parent organization websites. The specific standards are 
discussed in greater detail in the section-by-section review (see Sec.  
171.7).

IV. NPRM Comment Discussion

    In response to the November 27, 2018 NPRM [83 FR 60970], PHMSA 
received comments from the following organizations and individuals:

 Air Line Pilots Association, International (ALPA)
 Alaska Airlines
 Amazon
 American Coatings Association (ACA)

 National Retail Federation (NRF)
 The Rechargeable Battery Association (PRBA)
 Reusable Industrial Packaging Association (RIPA)
 Transport Canada (TC)
 U.S. Chamber of Commerce (Chamber)
 Utility Solid Waste Activities Group (USWAG)

    PHMSA received comments from the ACA, CGA, ALPA, IATA, DGAC, and 
the Chamber all providing general support for harmonization with 
international standards and additional support from CGA for the 
incorporation by reference of the proposed ISO standards. In addition, 
PHSMA received a comment from IME in support of updating the edition of 
the GHS that is incorporated by reference.

[[Page 27812]]

    Comments concerning the issuance of a direct final rule, the sunset 
provisions for polymerizing substances, compliance and applicability 
dates for the test summary, fuel gas containment systems, damaged and 
defective lithium batteries, competency based training, and safety 
devices in dedicated handling devices are discussed below. PHMSA 
concluded that comments made by Anonymous 2, portions of comments made 
by MDBTC concerning ``receipted for in one lot,'' in Sec.  173.185,\2\ 
portions of comments made by Alaska Airlines concerning air transport 
provisions for fish meal, and portions of comments made by IME 
concerning amendments to packaging instruction US 1 in Sec.  173.62,\3\ 
are outside the scope of this rulemaking. Therefore, PHMSA did not 
address these comments in this rulemaking. All other comments specific 
to the respective HMR sections are addressed in the ``Section-by-
Section Review'' of this document.\4\
---------------------------------------------------------------------------

    \2\ Section 173.185 defines consignment to mean ``one or more 
packages of hazardous materials accepted by an operator from one 
shipper at one time and at one address, receipted for in one lot and 
moving to one consignee at one destination address.''
    \3\ Section 173.62 establishes specific packing requirements for 
explosives. US 1 is a packing instruction that is ``particular to 
the United States and not found in applicable international 
regulations.''
    \4\ Comments which were outside the scope of this rulemaking are 
not addressed in this final rule.
---------------------------------------------------------------------------

Delays in Issuing the Final Rule

    PHMSA received a comment from AAR and ASLRRA that indicated the 
delay associated with publication of a final rule ``presents immediate 
challenges for shippers and carriers involved in the transportation of 
hazardous materials across U.S. borders'' and suggested alternative 
ways for proceeding with the rulemaking. PHMSA recognizes that a delay 
in publication of this final rule may have presented challenges for 
shippers and carriers. To mitigate these challenges, on December 18, 
2018, PHMSA issued a Notice of Enforcement Policy Regarding 
International Standards authorizing the use of the applicable 
international standards.\5\ The notice explained that PHMSA would not 
take enforcement action against any offeror or carrier using the 
updated standards when all or part of the transportation is by air with 
respect to the ICAO TI, or all or part of the transportation is by 
vessel with respect to the IMDG code.

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

Sunset Provisions for Polymerizing Substances

    In the March 30, 2017, final rule [HM-215N; 82 FR 15796], PHMSA 
added four new Division 4.1 entries for polymerizing substances to the 
HMT, and added defining criteria, authorized packagings, and safety 
requirements including, but not limited to, stabilization methods and 
operational controls into the HMR. 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 that 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. In the 
HM-215O NPRM, PHMSA proposed to extend the sunset dates for provisions 
concerning the transportation of polymerizing substances from January 
2, 2019 to January 2, 2021 as the research is still in progress. PHMSA 
received comments from BAMM, DGAC, and Dow expressing support for the 
extension of the sunset provisions proposed in the HM-215O NPRM. These 
commenters also requested that PHMSA harmonize the requirements for 
temperature control of polymerizing substances in portable tanks and 
testing requirements for these substances intended to be carried in 
portable tanks or intermediate bulk containers (IBCs) with those found 
in the transport international standards while awaiting the results of 
a currently underway research project.
    DGAC and Dow requested that the previously adopted changes to Sec.  
173.21 in the March 30, 2017, final rule [HM-215N; 82 FR 15796], 
requiring temperature control at 50 [deg]C for portable tanks carrying 
polymerizing substances be harmonized with the internationally adopted 
45 [deg]C, while PHMSA awaits the outcome of ongoing research into 
polymerizing substances. BAMM, DGAC, and Dow requested that PHMSA not 
require polymerizing substances intended to be transported in portable 
tanks or IBCs to undergo the Test Series E heating under confinement 
testing. The commenters requested that the provisions for polymerizing 
substances be harmonized with those found in the applicable 
international standards while PHMSA awaits the outcome of ongoing 
research into polymerizing substances. DGAC and Dow commented that 
differing domestic and international temperature control thresholds 
before temperature control is required would result in materials with a 
self-accelerating polymerization temperature (SAPT) greater than 45 
[deg]C and less than or equal to 50 [deg]C being subject to temperature 
control when transported in portable tanks in the United States, but 
not elsewhere in the world. BAMM, DGAC, and Dow expressed their view 
that because the recommended test methods for Test Series E were not 
specifically designed for polymerizing substances that the test results 
would be meaningless. The commenters did not raise any new reasons for 
not adopting the provisions beyond those previously addressed in the 
March 30, 2017 final rule [HM-215N; 82 FR 15796]. PHMSA understands the 
concerns raised by the commenters, but to ensure the safe and efficient 
transportation of these commodities, PHMSA is adopting the provisions 
as proposed in the NPRM and codified in the March 30, 2017, final rule 
for the reasons that were previously outlined [HM-215N; 82 FR 15796, 
15798-99]. In brief, the rationale for adopting the 50 [deg]C SAPT 
threshold before temperature control is required for transport in 
portable tanks is primarily that 50 [deg]C is the maximum temperature 
reasonable expected to be experienced by any selfreactive, organic 
peroxide, and/or polymerizing substance. The rationale for requiring 
Test Series E testing for polymerizing substances intended to be 
transported in portable tanks or IBC is that Test Series E (or an 
equivalent performance measure) provides information on how the 
material behaves when heated under confinement. For additional 
discussion of these issues refer to the March 30, 2017 final rule [HM-
215N; 82 FR 15796, 15798-99].
    To accommodate additional potential delays in completion and 
reviewing the results of the research project on polymerizing 
substances, PHMSA is extending the date for the sunset provisions for 
an additional two years beyond the date proposed in the NPRM. The new 
sunset date for transport provisions concerning polymerizing substances 
is January 2, 2023.

Lithium Battery Test Summary

    In the NPRM, PHMSA proposed the inclusion of lithium battery test 
summary requirements. The test summary includes a standardized set of 
elements that provide traceability and accountability to ensure that 
lithium cell and battery designs offered for transport contain specific 
information on the required UN tests. PHMSA proposed that manufacturers 
and subsequent distributers of lithium cells and batteries manufactured 
after June 30, 2003 must make test summaries available to others in the 
supply chain.

[[Page 27813]]

In the international standards, and as proposed in the NPRM, the 
lithium battery test summary requirements would have an effective date 
of January 1, 2020.
    In response to the comments received, in this final rule, PHMSA is 
providing additonal background on the test summary. The development of 
the test summary by the United Nations Sub-Committee of Experts on the 
Transport of Dangerous Goods spanned several years. The work was the 
outgrowth of an industry-identified problem concerning lack of 
availability of information needed to verify compliance and facilitate 
transportation. Specifically, the inability of shippers to access 
documentation verifying that lithium cells and batteries have 
successfully passed the tests prescribed in part III, sub-section 38.3 
of the UN Manual of Tests and Criteria. In 2014, a trade association 
representing major rechargeable battery manufacturers relayed to the UN 
Sub-Committee that shippers were experiencing difficulties in verifying 
compliance with the UN 38.3 tests (See UN/SCETDG/46/INF.11, paragraph 
15).\6\ It was the industry group's suggestion to work within the UN 
Sub-Committee towards a summary format that would facilitate making 
available essential compliance information to all concerned. This 
suggestion led the UN Sub-Committee over the next two years in 
cooperation with government and industry stakeholders to develop a 
standardized list of information to be included in a test summary (see 
ST/SG/AC.10/C.3/100, paragraph 56).\7\ PHMSA received several comments, 
which are discussed throughout this rulemaking and the associated RIA, 
concerning the potential costs of the test summary provisions. While 
providing no specific cost estimates, these commenters indicated that 
they believed implementing the test summary provisions as proposed 
would be more burdensome than PHMSA estimated. In this final rule, 
PHMSA is adopting changes to the compliance date, the implementation 
date, and several other variatons from the NPRM proposals that will 
reduce the burden on lithium cell and battery manufacturers and 
distributors.

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

Compliance Date

    PHMSA received comments from Alaska Airlines, Amazon, Chamber, 
COSTHA, DGAC, MDBTC, NRF, PRBA, and an anonymous commenter concerning 
the proposed effective date of January 1, 2020 for the proposed test 
summary requirements. These commenters requested that PHMSA provide 
additional time to comply. Alaska Airlines commented that they hope the 
test summary requirements can be implemented by January 1, 2021. PRBA, 
Amazon, MDBTC, the Chamber, and NRF indicated that PHMSA should allow 
manufacturers and subsequent distributors until January 1, 2022 to 
comply with the test summary requirements. The DGAC recommended a one-
year transition period following publication of the final rule. The 
commenters opined that the proposed compliance deadline of January 1, 
2020 would not allow sufficient time for U.S. manufacturers and 
subsequent distributors of these products to establish procedures for 
preparing and securing test summaries. In their comments, NRF commented 
that it will take significant time for manufacturers and shippers, 
especially small companies, to develop and prepare the test summaries 
for their products. NRF opined that a longer implementation time will 
give companies enough time to identify, develop, and prepare the 
materials that are needed for compliance.
    PHMSA agrees that additional time may be required to fully 
integrate systems, processes, and policies for preparing test 
summaries. The additional time can be used to help ensure the 
availability of test summaries and to prepare procedures for making 
test summaries available to subsequent distributors. In this final 
rule, the required compliance date for both the creation of and 
subsequent distribution upon request for test summaries is January 1, 
2022.
    COSTHA noted that using the same implementation date for both 
battery manufacturers and distributors presents the possibility that 
manufacturers could wait until December 31, 2021 to prepare the 
documents and distributors would not have any additional time to 
receive and make available the test summaries throughout the supply 
chain. COSTHA requested a staggered implementation date that would 
allow distributors an additional year to comply. PHMSA believes that 
the extended transition period for domestic implementation of the test 
summary requirements (two years after the requirements enter the IMDG 
Code and ICAO Technical Instructions) will mitigate this concern over 
shared implementation dates for shippers and distributors by providing 
additional time for battery distributers to work with manufacturers to 
acquire the necessary information and establish mechanisms for further 
distribution.

Applicability Date

    PHMSA received comments from PRBA, NRF, DGAC, MDBTC, Amazon, and 
the Chamber requesting that PHMSA reconsider which lithium batteries 
require a test summary be created and made available. PHMSA proposed a 
requirement that a test summary be made available for all lithium cells 
and batteries manufactured after June 30, 2003, and that 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.
    PRBA commented that ``[i]t is not practicable to require the post-
hoc generation of a Test Summary for batteries that were manufactured 
as far back as 2003,'' and asked that PHMSA adopt a date that requires 
the creation of test summaries and subsequent distribution for only 
batteries and cells manufactured after the effective date of the 
provisions. In conjunction with its request to extend the compliance 
date for the test summary generally to January 1, 2022, PRBA requests 
that only batteries and cells manufactured after this date require test 
summaries and subsequent distribution. The Chamber also requested that 
the applicability be limited to lithium cells and batteries 
manufactured after January 1, 2022 noting that ``there may be times 
when distributors are shipping older battery designs that were 
manufactured by a company that is no longer in business. In instances 
like this, it may be impossible for shippers to acquire the necessary 
information for the TS.'' The NRF and Amazon commented with similar 
requests to limit the scope of batteries subject to the test summary by 
using the effective date of the requirement which would then apply the 
requirements to cells and batteries currently in production and those 
made going forward. The NRF noted that it would be incredibly difficult 
and burdensome to locate a test certification and create a test summary 
for batteries dating back up to 17 years. MDBTC supported requiring 
test summary documents for only lithium cells and batteries 
manufactured after January 1, 2014.
    PHMSA recognizes the comments noting the potential difficulty in 
obtaining test summaries for older batteries, particularly in cases 
where a manufacturer may no longer be in business or has merged with 
another company. Therefore, PHMSA is applying the test summary 
requirements

[[Page 27814]]

only to cells and batteries manufactured after January 1, 2008. This 
date is the effective date of the final rule that required all lithium 
batteries (including small batteries) be of the type proven to meet the 
criteria in part III, sub-section 38.3 of the UN Manual of Tests and 
Criteria (``Hazardous Materials; Transportation of Lithium Batteries,'' 
August 9, 2007, 72 FR 44929). As of January 1, 2008, all batteries 
transported in accordance with the HMR should have valid test reports 
that will help facilitate the creation of and availability of test 
summaries. PHMSA believes that amending the scope of cells and 
batteries that require a test summary to those manufactured after 
January 1, 2008 will lead to fewer instances where insufficient 
information will be available to create the required test summary while 
still capturing the majority of batteries and cells being offered for 
transportation.
    PHMSA reiterates the importance of the test summary in providing 
confirmation 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. Additionally, PHMSA maintains 
that the creation and subsequent distribution of test summaries for 
lithium batteries provides an enhanced mechanism for shippers to meet 
their existing requirement to only offer lithium cells and batteries of 
a type proven to meet the criteria in part III, sub-section 38.3 of the 
UN Manual of Tests and Criteria. The availability of specific 
information in the test summary document will enhance the users' 
ability to obtain the information needed to ensure they are receiving, 
and potentially reoffering for transportation, a battery that is of a 
tested and approved type.

Fuel Gas Containment Systems

    In the NPRM, PHMSA discussed amendments to international standards 
that are not being considered for adoption. As stated in the NPRM, the 
20th Revised Edition to the UN Model Regulations added a special 
provision to allow for the transportation of vehicle fuel gas 
containment systems containing certain gases, such as compressed 
natural gas and liquified petroleum gas, transported for disposal, 
recycling, repair, inspection, maintenance, or from where they are 
manufactured to a vehicle assembly plant. The provisions allow for 
gaseous fuels to be transported in fuel tanks designed for vehicles 
meeting certain European automotive standards rather than specification 
pressure receptacles. In the NPRM, PHMSA explained that the vehicle 
specification pressure vessels that are incorporated and authorized by 
the UN Model Regulations do not apply to U.S. domestic transportation 
as most of the fuel gas containment standards that are addressed in the 
UN Model Regulations are more appropriate for European road and rail 
regulations. PHMSA solicited comments on the fuel gas containment 
systems amendment in the UN Model Regulations and asked whether it 
would benefit industry to include a similar amendment in the HMR.
    PHMSA received a comment from COSTHA on the decision not to include 
provisions for fuel gas containment decisions. The commenter disagreed 
with the view that the amendments are more appropriate for European 
regulations. COSTHA commented on the benefits of adopting the 
provisions into the HMR. COSTHA opined that when fuel tanks are removed 
from the vehicle and offered for transportation they are constructed to 
meet motor vehicle standards, but the tanks will not be permitted for 
transport of gaseous fuels under the HMR without the gas being 
completely removed from the tank. COSTHA further commented that the gas 
removal process has the potential to lead to dangerous situations at 
repair shops, dealers, and disposal locations not equipped to properly 
empty these fuel tanks. COSTHA notes that U.S. automobile manufacturers 
often use UN or Global Technical Regulations to demonstrate compliance 
with equivalent Federal Motor Vehicle Safety Standards (FMVSS).\8\ In 
addition, COSTHA supports referencing applicable FMVSS in the HMR to 
facilitate U.S. domestic gas containment system transport.
---------------------------------------------------------------------------

    \8\ National Highway Transportation Safety Administration issues 
FMVSS. The regulations establishing the FMVSS are primarily found at 
49 CFR part 571. https://www.nhtsa.gov/laws-regulations/fmvss.
---------------------------------------------------------------------------

    PHMSA thanks COSTHA for its comments on this topic, and PHMSA 
understands the concerns related to difficulties in ensuring gas is 
removed from these cylinders prior to transport, but it would be 
premature to adopt the FMVSS requirements into the HMR. The FMVSS 
requirements are not presently incorporated in the UN Model 
Regulations, and adoption of the FMVSS requirements would require 
additional coordination with Federal agencies outside of PHMSA. PHMSA 
may consider this action in a future rulemaking and invites COSTHA to 
file a petition for rulemaking in accordance with 49 CFR 106.95, 
106.100 and 106.105, to formally request this change be made in the 
HMR. Additonally, PHMSA believes that a more comprehensive review of 
the current domestic standards used by vehicle fuel gas containment 
systems is necessary prior to incorporation in the HMR to help ensure 
safety standards that most closely align with existing practices are 
incorporated. The request could be further evaluated for merit to 
address in an upcoming rulemaking.

Damaged and Defective Lithium Batteries

    In the NPRM, PHMSA discussed amendments to international standards 
not being considered for adoption. As stated in the NPRM, the 20th 
Revised Edition of the UN Model Regulations adopted transportation 
provisions for damaged and defective cells and batteries 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 (UN Nos. 
3090, 3091, 3480 and 3481). In the NPRM, PHMSA explained that the 
existing packaging and hazard communication requirements in Sec.  
173.185(f) sufficiently address consignments of this nature. PHMSA 
received one comment from MDBTC in support of not adopting the 
provisions for damaged and defective lithium batteries.

Competency-Based Training

    PHMSA received comments from AAR and ASLRRA, ACA, AHS, Alaska 
Airlines, CGA, COSTHA, DGAC, Dow, IATA, IME, Interested Parties, 
IVODGA, MDBTC, and RIPA in response to our request for comments on the 
principles of Competency-Based Training, recently published in the 
attachments of the ICAO Technical Instructions. As noted in the NPRM, 
the provisions concerning Competency-Based Training were not finalized 
or adopted in the 2017-2018 ICAO Technical Instructions and there were 
no proposals concerning this topic in the NPRM. PHMSA thanks all 
commenters for their views on the issue and, as noted in the NPRM, 
comments will be considered for the betterment of PHMSA's work in 
various international forums.

Safety Devices in Dedicated Handling Devices

    PHMSA received a comment from COSTHA concerning safety devices in 
dedicated handling devices. COSTHA commented that PHMSA should align 
the provisions of Sec.  173.166(e)(4)(i) with the UN Model Regulations 
and the IMDG Code to authorize unpackaged articles in dedicated 
handling devices, vehicles, or containers to, from, or

[[Page 27815]]

between where they are manufactured and an assembly plant including 
intermediate handling locations. PHMSA notes that the provisions 
adopted by the UN and the IMDG Code are currently authorized in 
Sec. Sec.  173.166(e)(4)(i) and (ii), therefore no additional action is 
required.

V. Section-By-Section Review

    The following is a section-by-section review of the amendments 
adopted in this final rule:

Part 171--General Information, Regulations, and Definitions

Section 171.7 Reference Material
    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 1995.'' 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,'' and in accordance 
with Sec 12(d)(1) of the ``National Technology Transfer and Advancement 
Act of 1995,'' government agencies must use voluntary consensus 
standards wherever practical in the development of regulations. When 
properly conducted, 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 it 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 final rule, PHMSA is adding and revising the following 
incorporation by reference materials:
     Paragraph (s)(2) is 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 addition of this paragraph 
corrects 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), 
2017-2018 Edition, is revised to incorporate the 2019-2020 Edition. 
These instructions contain the detailed instructions for the 
international transport of hazardous materials by air. In a previous 
rulemaking, [Docket No. PHMSA-2015-0102 (HM-219A); 83 FR 55792], PHMSA 
added Sec.  172.407 to the list of sections in paragraph (t)(1) and 
(v)(2). The NPRM did not account for this addition, and in this final 
rule Sec.  172.407 has been added to the list in paragraphs (t)(1) and 
(v)(2) consistent with the earlier published final rule.
     Paragraph (v)(2), which incorporates the International 
Maritime Organization International Maritime Dangerous Goods Code (IMDG 
Code), incorporating Amendment 38-16 (English Edition), is revised to 
incorporate the 39-18 (English Edition), 2018 Edition. This code 
contains detailed instructions for the international transport of 
hazardous materials by vessel.
     Paragraph (w), which incorporates various International 
Organization for Standardization entries, is 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 is 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. The updated version of ISO 11118 
includes, among other edits, clarified requirements for the processing 
of carbon steel to avoid strain aging and the inclusion of alternative 
temperatures for artificial aging of carbon steel cylinders prior to 
burst testing.
--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 is 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. The updated version of ISO 11120 includes, among 
other edits, the modification of ultrasonic provisions for ultrasonic 
examination in 8.3 to include ultrasonic examination for wall thickness 
and for imperfections also on the supplied tubing and revision of the 
provisions for design of tubes for embrittling gases.
--ISO 11623(E), Transportable gas cylinders--Periodic inspection and 
testing of composite gas cylinders, First edition, March 2002 is 
replaced by ISO 11623:2015(E), Gas cylinders--Composite construction--
Periodic inspection and testing 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. The updated version 
of ISO 11623 includes, among other edits, updated terminology, 
particularly for the various types of composite cylinders, and moves 
information regarding intervals between periodic inspection and testing 
based on cylinder type into the new Annex C (formerly listed in Tables 
1 through 4).
--ISO 14246:2014(E), Gas cylinders--Cylinder valves--Manufacturing 
tests and examination is added in paragraph (w)(69). This standard 
covers the function of a cylinder valve as a closure.
--ISO 16148:2016(E), Gas cylinders--Refillable seamless steel gas 
cylinders and tubes--Acoustic emission examination (AT) and follow-up 
ultrasonic examination (UT) for periodic inspection and testing is 
added in paragraph (w)(71). This International Standard describes two 
methods of AT, defined as Method A and Method B, and a method of

[[Page 27816]]

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 is added in paragraph (w)(72). This 
standard covers the function of a quick-release cylinder valve as a 
closure.
--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 added in 
paragraph (w)(75). This standard provides 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 is added in paragraph (w)(76). This 
standard specifies the requirements for the inspection and maintenance 
of cylinder valves, including valves with integrated pressure 
regulators.
--ISO/TR 11364:2012(E), Gas cylinders--Compilation of national and 
international valve stem/gas cylinder neck threads and their 
identification and marking system is 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.

     Paragraphs (aa)(1)-(4), which updates four (4) existing 
Organization for Economic Cooperation and Development (OECD) guidelines 
concerning corrosivity testing (Nos. 404, 430, 431, & 435). The 
references to these standards are updated to the 2015 versions of the 
standards. Updated 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. Updated OECD Guideline 430 and OECD Guideline 431 
include references to a developed document on integrated approaches to 
testing and assessment.
     Paragraph (bb)(1), which incorporates the Transport Canada 
Transportation of Dangerous Goods Regulations, adds 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 additions are to incorporate changes to 
the Transport Canada Transportation of Dangerous Goods Regulations. 
SOR/2016-95 contains amendments concerning reporting requirements and 
international restrictions on lithium batteries. SOR/2017-137 contains 
amendments related to international harmonization. SOR/2017-253 
containes amendments related to marine transportation.
     Paragraph (bb)(2) is 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, is 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. In a previous rulemaking, [Docket No. 
PHMSA-2015-0102 (HM-219A); 83 FR 55792], PHMSA added Sec.  172.519 to 
the list of sections in paragraph (dd)(1). The NPRM did not account for 
this addition and in this final rule, Sec.  172.519 has been added to 
the list in paragraph (dd)(1) consistent with the earlier published 
final rule.
     Paragraph (dd)(2)(ii) is 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), is revised to incorporate the United Nations 
Recommendations on the Transport of Dangerous Goods, Globally 
Harmonized System of Classification and Labelling of Chemicals (GHS), 
Seventh revised edition (2017). This standard helps identify the 
intrinsic hazards found in substances and mixtures and to convey 
information about these hazards.
Section 171.8 Definitions and Abbreviations
    Section 171.8 defines terms generally used throughout the HMR that 
have broad or multi-modal applicability. In this final rule, PHMSA is 
amending the definition of ``UN pressure receptacle'' to include 
pressure drums. Additionally, PHMSA is adding 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 incorporated in 
Sec.  178.71.
Section 171.12 North American Shipments
    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 
15796], PHMSA amended the HMR to expand recognition of cylinders and 
pressure receptacles, cargo tank repair facilities, and certificates of 
equivalency (an authorization to conduct an activity in compliance with 
the conditions of that authorization instead of the standard 
requirements) 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 final rule, 
PHMSA is clarifying 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 final 
rule, PHMSA is amending paragraph (a)(1) to clarify the extent of 
reciprocity regarding certificates of equivalency.
    Additionally, PHMSA is amending paragraph (a)(3)(v) to update the 
standard incorporated by reference to

[[Page 27817]]

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).
    PHMSA received comments of general support from the Dow and DGAC. 
Dow specifically mentioned support for the incorporation by reference 
of the Containers for Transport of Dangerous Goods by Rail and 
clarification of the certificates of equivalency.
    PHMSA received a comment from Transport Canada suggesting that the 
terms ``pressure drum'' and ``pressure receptacle'' addressed in Sec.  
171.8 of this final rule, also be included in Sec.  171.12 in a manner 
that promotes reciprocity between the United States and Canada. We 
agree with the commenter and in this final rule are adding the terms 
``pressure drum'' and ``UN pressure receptacle'' to Sec.  171.12 and 
authorizing use of these packages when marked with the letters ``CAN.''

Part 172--Hazardous Materials Table, Special Provisions, Hazardous 
Materials Communications, Emergency Response Information, Training 
Requirements, and Security Plans

Section 172.101 Purpose and Use of Hazardous Materials Table
    Section 172.101 contains the HMT and provides instructions for its 
use. In this final rule, PHMSA is revising 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. In the NPRM, PHMSA proposed a revision to 
paragraph (e) to indicate that NA numbers are only recognized for use 
in the United States. In the NPRM, PHMSA stated that NA numbers are not 
authorized in Canada because the TDG limit the use of NA numbers to 
materials classified as ``Consumer commodity,'' and do not allow for 
the use of other NA numbers. Transport Canada made this amendment in 
August 15, 2001 with SOR 2001-186.\9\ The TDG, Part 9.1 Transporting 
Dangerous Goods from the United States into or through Canada state 
that the HMR may be followed as an alternative to the TDG if certain 
conditions are met, including that ``the classification in Schedule 1 
or in the UN Recommendations, for dangerous goods that have the letter 
``D'' assigned to them in column 1 of the table to section 172.101 of 
49 CFR, except for dangerous goods with the shipping name `Consumer 
commodity'.'' The letter ``D'' is assigned to NA numbers. Therefore, NA 
numbers are not recognized for shipments from a place in the United 
States to a place in Canada or from a place in the United States 
through Canada to a place outside Canada. As such, PHMSA is revising 
the HMR to be consistent with Canada's national regulations. PHMSA 
received comments from DGAC on the use of NA numbers in Sec.  
172.101(e), North American Shipments. Specifically, DGAC stated this 
change will eliminate mutual recognition of NA numbers between the 
United States and Canada. Although the text in Sec.  172.101(e), 
stating that NA numbers are not recognized for international 
transportation, except to and from Canada, was not previously amended 
to align with the TDG, the mutual recognition of NA numbers has not 
been permitted under the TDG since the August 15, 2001 publication. NA 
numbers will continue to be recognized for shipments within the United 
States.

1. Hazardous Materials Table (HMT)
    In this final rule, PHMSA is amending the HMT. Readers should 
review all changes for a complete understanding of the amendments. For 
purposes of the U.S. 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.'' The amendments to the HMT include the 
following:
2. 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 in contact with 
water emits flammable gases, 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 is adding 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 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 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 (PG) 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 that are 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. PHMSA 
received one comment on the proposed changes to Sec.  172.101 from PRBA 
supporting the new entry of UN3536 in the table.
3. 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,

[[Page 27818]]

as the substance has been determined to polymerize in certain 
conditions.
4. 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 reverts 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 addresses 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.
5. 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 modifications to the entries in the HMT are discussed below.
    In an October 18, 2018, final rule, entitled ``Notification of the 
Pilot-in-Command and Response to Air Related Petitions for Rulemaking'' 
[(HM-259); 83 FR 52878], PHMSA removed special provision A6 from UN 
numbers 2789, 2790, 1715, 1717, 1723, 1732, 1739, 1758, 2240, 3264, 
3265, 1764, 1765, 1768, 1775, 1776, 1778, 1777, 1782, 1786, 1790, 2031, 
2308, 1808, 2258, 2879, 1818, 2564, 2699, 2502, 2443, and 2444. 
However, the HM-215O NPRM incorrectly showed special provision A6 as 
still being applicable to these entries. Therefore, in this final rule, 
A6 is not assigned to these HMT entries consistent with the previously 
published HM-259 final rule.
    Similarly, in the HM-259 final rule, PHMSA removed special 
provision A3 from UN numbers 1739, 2604, 1758, 2240, 1183, 1777, 1242, 
1798, 1873, 2879, 1828, 1831, 2699, and 2444. However, the HM-215O NPRM 
incorrectly showed special provision A3 as still being applicable to 
these entries. Therefore, in this final rule, A3 is not assigned to 
these HMT entries consistent with the previously published HM-259 final 
rule.
    Finally, in a March 6, 2019, interim final rule (IFR) [(HM-224I); 
84 FR 8006], PHMSA removed special provision A51 from UN3480 and added 
special provision A100 to UN 3480. However, the HM-215O NPRM did not 
account for this action and in this final rule, A51 is removed from 
UN3480 and A100 is added to UN 3480 consistent with the previously 
published HM-224I IFR.
    See ``Section 172.102 special provisions'' below for a detailed 
discussion of the additions, revisions, and deletions to the special 
provisions addressed in this final rule.
     Special provision 325. Special provision 325 is added to 
the following HMT entries:

     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. The 6(d) test is a test on a 
single package to determine if there are hazardous effects outside the 
package arising from accidental ignition or initiation of the contents. 
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 Division 1.4S articles and substances that are generic or 
``not otherwise specified'' (n.o.s.), and to UN 0367 (Fuzes, 
detonating) that are normally package dependent. The UN Working Group 
noted that generic entries normally warrant more systematic testing. In 
the NPRM, PHMSA requested comment on whether this provision is likely 
to have net benefits. PHMSA received one comment from IME stating that 
the ``addition of the special provision will benefit transportation 
safety and that the additional costs are, accordingly justified.'' 
Therefore, in this final rule, consistent with the UN Model 
Regulations, PHMSA is adding 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.

     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 Sub-
Committee of Experts (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 
final rule, PHMSA is assigning special provision 368 to the following 
entry to aid shippers:

UN2908 Radioactive material, excepted package--empty packaging.

     Special provision 369. Special provision 369 is revised 
for clarity and is applicable to the following HMT entry:

UN3507 Uranium hexafluoride, radioactive material, excepted package, 
less than 0.1 kg per package, non-fissile or fissile-excepted

     Special provision 383. Consistent with the deletion of 
this special provision in section 172.102, special provision 383 is 
removed from the following PG II HMT entries:

     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, special provision W40 is removed from 
the following HMT entries:

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

    Additionally, PHMSA is adding special provision W40 to the 
following HMT entry:

UN3208 Metallic substance, water-reactive, n.o.s. (PG II)
6. 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.
    In the NPRM, PHMSA proposed to amend various vessel stowage codes 
assigned to explosives articles to allow under deck stowage of these 
articles when not in closed cargo transport units (CCTUs). PHMSA 
received a comment from IME noting support for the changes, but 
indicating that the commercial ports used by their industry in the 
United States require commercial explosives to be containerized 
regardless of whether they are shipped on deck or under deck. PHMSA 
reiterates that these changes also allow the shipment of large and 
robust articles that while generally contained in some manner (e.g. a 
custom built crate, cradle, or box) may not fit in a traditional CCTU. 
The changes made in this final rule authorize such transport when not 
in a traditional CCTU. While these changes do not authorize the break 
bulk stowage of explosive substances, they

[[Page 27820]]

do facilitate the movement of larger explosive articles.
    The following table addresses this issue through modification of 
the stowage categories for individual UN numbers for which under deck 
stowage was previously permitted prior to Amendment 36-12 of the IMDG 
Code. Table 2 contains the changes listed in numerical order by UN 
identification number and additionally lists the proper shipping name, 
the previous column (10A) entry, and the adopted column (10A) entry.

    Consistent with changes to Amendment 39-18 of the IMDG Code, PHMSA 
is making 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 is applying 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 is adding 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 is adding 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 is adding stowage code 25 to 
Dipropylamine, UN 2383 consistent with changes adopted in Amendment 39-
18 of the IMDG Code.
    PHMSA is adding 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 final rule, PHMSA is adding existing vessel stowage code 74 and 
new vessel stowage codes 151 and 153 to UN 2977 and UN 2978. 
Additionally, PHMSA is adding new vessel stowage code 152 to UN 3507. 
Stowage code 74 requires stowage separated from oxidizers. See a 
section-by-section discussion on the proposed changes to Sec.  176.84 
for a description of stowage codes 151, 152 and 153. These amendments 
are necessary to ensure appropriate stowage and segregation provisions 
that account for the subsidiary and tertiary hazards of these 
commodities.
    Finally, we are adding new stowage provision 154 and assigning it 
to the NA 0124, NA 0494, UN 0494, and UN 0124 jet perforating gun HMT 
entries. This 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.

7. Appendix B to Sec.  172.101--List of Marine Pollutants
    Appendix B to Sec.  172.101 lists marine pollutants regulated under 
the HMR. Based on the 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 final rule, PHMSA is 
amending 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 packaging requirements, prohibitions, and exceptions applicable 
to particular quantities or forms of hazardous

[[Page 27826]]

materials. In this final rule, PHMSA is revising the following 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 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 
final rule, PHMSA is revising 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 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 final rule, PHMSA is revising 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 
the requirements for neutron radiation detectors containing boron 
trifluoride. In a final rule published under [(HM-215N); 82 FR 15796], 
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. Therefore, PHMSA is 
removing 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 is adding 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 final rule, PHMSA is assigning 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 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 final rule, PHMSA is revising the first sentence of 
the special provision for editorial clarity by replacing the words ``a 
radioactive material and corrosive subsidiary risk'' with 
``radioactivity and corrosive subsidiary risks.''
     Special provision 383. PHMSA is removing 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). Amendments to Sec.  173.121 in this final 
rule 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 
special provision 383 currently offers, and is deleting special 
provision 383 and removing the special provision from the HMT for those 
entries to which it is assigned.
     Special provision 387. Special provision 387 is revised to 
extend the sunset dates for provisions concerning the transportation of 
polymerizing substances from January 2, 2019, to January 2, 2023.
     Special provision 388. Consistent with the UN Model 
Regulations, PHMSA is adding 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 is adding 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.
    This special provision, which captures many of the safety elements 
included in previous approvals issued by PHMSA, specifies 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

[[Page 27827]]

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, other hazardous materials 
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'' adopted 
in this rulemaking, PHMSA is adding 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 421. Special provision 421 is revised to 
extend the sunset dates for provisions concerning the transportation of 
polymerizing substances from January 2, 2019 to January 2, 2023.
     Special provision 422. PHMSA is 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 
the requirements for radioactive materials with subsidiary hazards when 
transported by aircraft. In this final rule, PHMSA is revising special 
provision A56 consistent with the revisions made to special provision 
A78 in the 2019-2020 ICAO Technical Instructions. Specifically, where 
the subsidiary hazard material is listed as ``Forbidden'' in column 
(9A) or (9B) of the Sec.  172.101 Table, the radioactive material may 
only be offered for transportation and transported by aircraft under 
conditions approved by the Associate Administrator.
     Special provision A105. PHMSA is revising 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 is adding 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
UN1386 Seed cake with more than 1.5 percent oil and not more than 11 
percent moisture
UN1398 Aluminum silicon powder, uncoated
UN1435 Zinc ashes
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 is revising 
Portable Tank Special Provision TP10, assigned to UN 1744, to authorize 
a three-month extension for the transportation of bromine portable 
tanks for the purposes of performing the next required liner 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 flammable gases when in contact with 
water at the rate and quantity meeting the classification requirements 
for a Division 4.3 material, 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. Consistent with the IMDG Code PHMSA is deleting special provision 
W32 and assigning W31, which requires non-bulk packagings to be 
hermetically sealed regardless of the form of the material.
Section 172.203 Additional Description Requirements
    Section 172.203 prescribes additional description requirements for 
shipping papers. In the NPRM, PHMSA proposed revising Sec.  
172.203(o)(2), to require that the words ``TEMPERATURE CONTROLLED,'' 
when appropriate, be added to the proper shipping name for Division 4.1 
(polymerizing substance and self-reactive) and Division 5.2 (organic 
peroxide), if not already indicated in the HMT. PHMSA received a 
comment from DGAC noting that the HMT lists only four (4) n.o.s. 
entries for ``polymerizing materials,'' two of which identify that the 
material is stabilized and the other two of which already include the 
words ``temperature controlled.'' Therefore, the commenter states that 
the addition of ``polymerizing substances'' to this listing is 
unnecessary. PHMSA points out that polymerizing substances are not 
limited to the four (4) n.o.s. entries, but also include HMT entries 
assigned special provision 387. While it may be the case that all 
organic peroxides and self-reactive materials that require temperature 
control are assigned to HMT entries that include the words 
``temperature control'' the same does not apply to polymerizing 
substances. Therefore, in this final rule PHMSA is revising paragraph 
(o)(2) as proposed in the NPRM. This amendment provides notice to those 
in the transport chain that a material is being offered under 
temperature control.
    In the NPRM, PHMSA proposed revising paragraph Sec.  172.203(o)(3) 
by requiring that for samples of polymerizing substances, the word 
``SAMPLE'' must be included in association with the basic description.

[[Page 27828]]

PHMSA received comments from DGAC and Dow. Both commented that the 
corresponding regulatory reference in paragraph (o)(3) to Sec.  
173.224(c)(3) applies to self-reactive substances but not to 
polymerizing substances, and noted that there are no equivalent 
requirements in the HMR for samples of polymerizing substances. DGAC 
also noted that requiring the word ``SAMPLE'' for all polymerizing 
substances would create disharmony with the provisions in the IMDG 
code, which only require ``SAMPLE'' to be included on the transport 
document for self-reactive materials and organic peroxides. PHMSA 
agrees with the commenters and is not revising paragraph (o)(3) in this 
final rule.
    Additionally, PHMSA is adding polymerizing substances to the list 
of types of materials that the additional documentation requirements in 
paragraph (o) apply to.
Section 172.407 Label Specifications
    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 amending 
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 amending 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 
October 1, 2014) to continue to be used until December 31, 2018, is 
removed and reserved. PHMSA received comments from IME, DGAC and MDBTC 
expressing support for the revision of label border specifications. 
Yvonne Keller commented that changes to Sec.  172.407 (c)(1) that were 
made in a previous final rule on Nov. 7, 2018 [(HM-219A); 83 FR 55792], 
would be overwritten by the proposed changes in the NPRM. The changes 
to (c)(1) in this rulemaking were intentional and consistent with 
changes made to international standards and adequately account for the 
changes to this paragraph in HM-219A.
Section 172.514 Bulk Packagings
    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 final rule, PHMSA is allowing flexible bulk containers to be 
placarded on two opposing sides. PHMSA received a comment from DGAC 
supporting the changes to placarding requirements for flexible bulk 
containers.
Section 172.604 Emergency Response Telephone Number
    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 
15796], PHMSA harmonized the HMR with international regulations by 
adopting separate HMT entries for internal combustion engines based on 
the fuel, (e.g., 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 final rule, PHMSA is amending paragraph (d)(2) to list 
all possible proper shipping names for engines per the original intent. 
PHMSA received a comment from DGAC supporting the change to the 
requirements for shipping descriptions of internal combustion engines. 
In a previous rulemaking [(HM-219A); 83 FR 55792], PHMSA made 
amendments to Sec.  172.604 to clarify that excepted quantities do not 
require an emergency response telephone number. This final rule amends 
the same section, but accounts for the changes made in HM-219A.
Section 172.800 Purpose and Applicability
    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 material that is incorporated by reference into the HMR it was 
noted that the International Atomic Energy Agency (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 
final rule, PHMSA is incorporating by reference the IAEA Code of 
Conduct on the Safety and Security of Radioactive Sources into 
paragraph (b)(15). Furthermore, we are revising 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 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--Shippers--General Requirements for Shipments and Packagings

Section 173.2a Classification of a Material Having More Than One Hazard
    Section 173.2a outlines classification requirements for materials 
having more than one hazard. PHMSA is amending paragraph (a) to 
indicate the appropriate classification precedence for the new 
``Articles'' HMT entries added in this final rule. This change gives 
guidance to offerors and shippers using the new HMT entries numbers 
that do not conform to a single hazard class.
Section 173.6 Materials of Trade Exceptions
    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 15796], 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 specific articles containing hazardous materials 
indicated in Table 4 below. This removal of an indication of packing 
group for these materials and articles has led to questions about the 
ability of these materials and articles to utilize the MOTs exceptions 
provided in Sec.  173.6. Further, this final rule adds 12 new proper 
shipping names for articles that

[[Page 27829]]

are also not assigned a packing group. See ``Section 172.101 Hazardous 
Materials Table (HMT)'' for a detailed discussion of this addition.
    It was not the intention of these previous rulemakings 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 final rule, PHMSA is adding a new paragraph 
(a)(7) to clarify that materials and articles for which Column (5) of 
the HMT 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. For all materials and articles 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 packaging meeting either 
Packing Group II or III performance level or non-specification 
packaging. Therefore, the quantity limits in the new paragraph (a)(7) 
will reference the PG II or PG III limits in Sec.  173.6(a)(1)(ii) or 
Sec.  173.6(a)(3) for articles containing Division 4.3 materials, as 
appropriate. PHMSA received a supporting comment from USWAG stating: 
``We are pleased to note that PHMSA has proposed this change in the 
current rulemaking. We appreciate PHMSA's efforts to correct this 
important oversight.'' In addition, PHMSA is revising paragraph (b)(3) 
to clarify the securement requirement for the transportation of 
articles under the MOTs exceptions.

Section 173.21 Forbidden Materials and Packages
    Section 173.21 describes the situations in which the offering for 
transport or transportation of materials or packages is forbidden. In 
this final rule, PHMSA is reinstating the provisions adopted in the HM-
215N final rule. A delayed effective date of January 2, 2019 was placed 
on amendment 22 of the HM-215N final rule, which reinstated the 
provisions of Sec.  173.21 in place prior to publication of that rule. 
Section 173.21 was not mentioned in the NPRM for this final rule 
because there was no amendment to make at the time, as the effective 
text of the section on the date of publication of the NPRM was the text 
we are reinstating in this final rule. The provisions that previously 
sunset on January 2, 2019 are reinstated in this final rule. PHMSA is 
extending the date for the sunset provisions for an additional two 
years versus the date proposed in the NPRM. The new sunset date for 
transport provisions concerning polymerizing substances is January 2, 
2023. This addition is consistent with the discussion above on 
polymerizing substances and associated research in the background and 
comment discussion sections of this rulemaking.
Section 173.62 Specific Packaging Requirements for Explosives
    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 increasing 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 adopting this additional requirement for steel end caps noting the 
safe transportation record of these explosive articles under the 
existing requirements of the HMR. PHMSA received one comment from IME 
supporting the increase in the maximum authorized amount of explosive 
contents per tool pallet and cargo vessel compartment and PHMSA's 
decision to not require steel end caps, leaving the existing HMR 
requirement intact.
Section 173.121 Class 3--Assignment of Packing Group
    Section 173.121 provides the 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 amending 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 noted that both the UN 
Model Regulations and The European Agreements Concerning the 
International Carriage of Dangerous Goods by Road and Rail 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

[[Page 27830]]

rail since the introduction of the provision.
    This change will increase the allowed volume of viscous liquids in 
a single package and will be applicable to all modes except for air. 
Specifically, in this final rule, PHMSA is increasing the packaging 
limits for viscous flammable liquids of Packing Group II material that 
may be assigned Packing Group III. For transport by vessel, PHMSA is 
increasing the limit from 30 L to 450 L. For transport by rail and 
highway, PHMSA is increasing the limit from 100 L to 450 L. Consistent 
with the ICAO Technical Instructions, the packaging quantity limits for 
air will remain 30 L for passenger aircraft and 100 L for cargo 
aircraft.
Section 173.124 Class 4, Divisions 4.1, 4.2 and 4.3--Definitions
    Section 173.124 contains definitions for Class 4, Divisions 4.1, 
4.2, and 4.3. In this final rule, PHMSA is amending paragraph 
(a)(4)(iv) to extend the sunset dates for provisions concerning the 
transportation of polymerizing substances from January 2, 2019, to 
January 2, 2023. See the background and comment discussion sections of 
this rulemaking for a more detailed discussion on polymerizing 
substances.
Section 173.127 Class 5, Division 5.1--Definition and Assignment of 
Packing Groups
    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 UN Manual of Tests and Criteria and the UN Model Regulations was 
amended or removed to avoid duplicative provisions in both 
publications. In this final rule, PHMSA is revising the classification 
criteria for 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 changes will 
not result in changes to the current classification provisions for 
ammonium nitrate fertilizers, but rather consolidate the provisions for 
ease of use and to prevent inadvertent misclassification.
Section 173.134 Class 6, Division 6.2--Definitions and Exceptions
    Section 173.134 provides definitions and exceptions for infectious 
substances. Consistent with the UN Model Regulations, PHMSA is revising 
the definition for ``patient specimen'' in paragraph (a)(4) by removing 
redundant references to humans and animals.
Section 173.136 Class 8--Definitions
    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 text in Chapter 3.2 of the UN GHS and the 
OECD Test Guidelines for Testing of Chemicals. PHMSA is amending the 
definition in paragraph (a) for a corrosive material by replacing the 
text ``full thickness destruction'' with ``irreversible damage.'' 
Harmonized terminology increases understanding and reduces the 
potential for confusion between those in the transport and storage and 
use sectors.
Section 173.137 Class 8--Assignment of Packing Group and Appendix I to 
Part 173
    Section 173.137 prescribes the requirements for assigning a packing 
group to Class 8 (corrosive) materials. Currently, the HMR require 
offerors to classify Class 8 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. Data obtained 
from the currently authorized test methods is the only data acceptable 
for classification and assignment of a packing group. In this final 
rule, consistent with changes to the UN Model Regulations, PHMSA is 
adding alternative packing group assignment methods for making a 
corrosivity classification determination for mixtures that do not 
involve testing. These amendments include bridging principles and a 
calculation method for the classification of mixtures. Bridging 
principles include; dilution, batching, concentration of mixtures of PG 
I, interpolation within one packing group, and provisions for 
substantially similar mixtures.
    In a new paragraph (d), PHMSA is 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. When there is not 
sufficient information to determine a packing group using the non-
testing methods described in paragraph (d), the testing and criteria in 
Sec.  173.137 introductory paragraph and (a)-(c) must be applied. To 
emphasize this point, PHMSA is adding an additional line to Figure 1 in 
paragraph (d) to state that in such cases the testing and criteria in 
Sec.  173.137 introductory paragraph and (a)-(c) must be applied to the 
mixture. This tiered approach ensures an appropriate level of safety in 
situations where reliable test data on that specific mixture may not be 
available. These alternatives for classifying corrosive mixtures 
provide opportunities for offerors 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 UN 
Model Regulations corrosivity requirements. For example, the use of 
extreme pH values to assign corrosivity was not addressed in the UN 
Model Regulations, and as such is not adopted in this final rule.
    PHMSA is replacing all instances of the text ``full thickness 
destruction'' with ``irreversible damage'' consistent with the change 
to the definition of a corrosive material in Sec.  173.136. PHMSA is 
also adding a new Appendix I to part 173, containing a flow chart for 
use with the calculation method.
    The corrigendum to the 20th Revised edition of the UN Model 
Regulations made several corrections to the calculation method 
classification criteria that were not included in the NPRM. Consistent 
with the UN Model Regulations, the last sentence of paragraph 
(d)(2)(i)(B) in the NPRM was added to a new paragraph (d)(2)(i)(B) and 
the following subparagraphs were renumbered accordingly. The new 
paragraph (d)(2)(i)(B) provides additional guidance on the use of the 
flow chart added in Appendix I to part 173.
    Finally, PHMSA is updating 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 
addresses in vivo testing and OECD Guidelines 430, 431, and 435 address 
in vitro testing. 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.

[[Page 27831]]

Section 173.159 Batteries, Wet
    Section 173.159 prescribes the 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 making several 
editorial amendments in paragraphs (a) and (d) to specify that 
electrically non-conductive packaging materials must be used and that 
contact with other electrically conductive materials must be prevented.
Section 173.185 Lithium Cells and Batteries
    Section 173.185 prescribes requirements for lithium cells and 
batteries. The introductory paragraph defines terms as used in this 
section. 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 final rule, PHMSA clarifies in 
paragraph (a)(1) that a single cell battery is considered a ``cell'' 
and must be transported in accordance with the requirements for cells. 
PHMSA is also amending Sec.  173.185(a) to include a lithium cell and 
battery test summary (TS) with a standardized set of elements. 
Manufacturers and subsequent distributers of lithium cells and 
batteries manufactured on or after January 1, 2008 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 that 
are offered and reoffered for transport contain specific information on 
the required UN tests.
    PHMSA received comments on the test summary from Alaska Airlines, 
Amazon, the Chamber, COSTHA, DGAC, IATA, MDBTC, NRF, and PRBA. MDBTC 
noted ``our Council understands the rationale behind the TS Document 
and, if implemented effectively, agrees with PHMSA and international 
regulators that making vital battery information more accessible will 
enhance the safety of all lithium battery shipments.'' IATA commented 
that it believes ``the availability of the test summary will improve 
safety by providing clear visibility that the lithium cell and battery 
types have been tested as required.'' Amazon commented that there are 
other effective methods for improving the safe transportation of 
lithium batteries, including common safety messaging across the supply 
chain, expanding supplier outreach, and improved packaging methods. 
Amazon noted that the test summary requirements, if implemented 
strategically and with appropriate clarity, could complement these 
other measures. However, Amazon suggested that additional outreach may 
be needed to ensure manufacturers and suppliers are informed of the new 
test summary requirements. Amazon further states that there is no 
publicly available data that supports the claim that the test summary 
requirement would improve the safe transport of lithium batteries. 
PHMSA recognizes that internal process improvements implemented by 
shippers (e.g., supplier outreach and common safety messaging) may also 
positively impact lithium battery transportation safety. Additionally, 
PHMSA is aware of, and is participating in, ongoing research into 
packaging solutions and classification criteria for lithium batteries. 
As previously stated, PHMSA believes that the test summary will ensure 
shippers are verifying that a cell or battery is from a legitimate and 
compliant source, and allow those in the transport chain to more easily 
identify non-counterfeit products.
    Comments on the compliance date and applicability date for the 
lithium battery test summary are addressed in the ``Comments Received'' 
section of this rulemaking. The requests that PHMSA reexamine the test 
summary document's impact for businesses, specifically small 
businesses, are addressed in the ``Information Collection'' section of 
this rulemaking and the Regulatory Impact Analysis (RIA). The remaining 
comments received regarding the proposed test summary requirements 
requested clarifications on terminology and when the document must be 
made available, exceptions for button cell batteries, and additional 
clarification of the docketed guidance document.
Requests for Clarification on Terminology and When the TS Must Be Made 
Available
    PHMSA received a comment from COSTHA that asked for clarification 
that in addition to being required for cells and batteries, a test 
summary is only required for equipment where the safety components of 
the equipment are necessary for the cells or batteries contained to 
pass the relevant UN sub-section 38.3 tests (e.g., when the overcharge 
protection for a battery is part of the equipment circuit board and not 
installed in the battery), and would not be required for all devices 
containing lithium batteries. In response to this comment, PHMSA would 
like to clarify that a test summary document is required for all cells 
and batteries manufactured on or after January 1, 2008, without regard 
to whether they are transported as standalone shipments, contained in 
equipment, packed with equipment, or used in vehicles. As noted in the 
``New UN Requirements for Lithium Battery Test Summaries'' \10\ 
guidance document found in the docket for this rulemaking, product 
manufacturers of devices containing lithium batteries are not required 
to create new test summary documents for their products if compliant 
test summaries have been created and are made available for the 
batteries contained in those products. Product manufactuerers may use 
existing test summaries for the batteries in their devices to meet 
their obligation to make them available to subsequent distributors. 
PHMSA also understands that there may be instances where device 
manufacturers desire to create a test summary for a product containing 
a lithium cell or battery. While not required, creating a test summary 
for a specific device rather than using an existing test summary 
applicable to a battery installed in the device is authorized if the 
required elements of the test summary are provided.
---------------------------------------------------------------------------

    \10\ https://www.regulations.gov/document?D=PHMSA-2017-0108-0008.
---------------------------------------------------------------------------

    Amazon requested that PHMSA require that manufacturers create a 
complete test summary for each lithium battery and lithium battery 
product and require that manufacturers post the summary online for 
widespread access for anyone in the supply chain. As proposed in the 
NPRM and adopted in this final rule, manufacturers and each subsequent 
distributor of lithium cells or batteries must make available test 
summaries as specified in Sec.  173.185. PHMSA expects that the first 
entity offering the cell or battery into transport would likely create 
the document for use by subsequent offerors or end users. However, the 
HMR intentionally do not specify who must create the test summary to 
provide implementation flexibility. The ``make available'' phrase is 
also intentional to allow for compliance through any means 
manufacturers and subsequent distributors find best fits their business 
needs and capabilities. Any method that ensures the information is made 
available to downstream distributors would be acceptable. This includes 
the envisioned least burdensome method of posting the information or 
links to the information on websites. Other possible methods include, 
but are not limited to, emailing copies of the required

[[Page 27832]]

information or providing physical hard copies with shipments.
    PHMSA received comments from Amazon, COSTHA, MDBTC, and NRF 
regarding the entity in the transportation chain that must make the 
test summary available and the phrase ``each manufacturer and 
subsequent distributor.'' Amazon and NRF commented that because the 
supply chain for lithium batteries involves many different entities 
acting in different roles, the phrase ``subsequent distributor'' should 
be defined. Amazon and NRF suggested that PHMSA clarify ``subsequent 
distributor'' by defining it as limited to entities and persons who 
possess and transfer title to lithium batteries and lithium battery 
products. MDBTC commented that one of the most challenging aspects of 
implementing the test summary requirement will be to clearly delineate 
the role of a ``subsequent distributor.'' COSTHA requested that PHMSA 
confirm that the use of the term ``distributor'' is only to emphasize 
that proof of successful design type testing is needed by shippers of 
lithium batteries, and that distributors are the logical persons to 
have such information needed for the TS, and that ultimately it is the 
shipper's responsibility to obtain the information for proof of 
classification. COSTHA also commented that the terms ``offerors'' and 
``subsequent offerors,'' which are more commonly used in transportation 
regulations, would provide more clarity. We confirm COSTHA's 
understanding that in addition to manufacturers, distributors of 
lithium batteries are a logical entity to have information needed for a 
TS and that a shipper or offeror of lithium batteries is the person 
ultimately responsible for ensuring that lithium cells and batteries 
offered for transport contain specific information on the required UN 
tests. In response to the requests to define ``subsequent 
distributor,'' PHMSA does not believe that a definition of ``subsequent 
distributor'' is necessary, as the intent is simply to indicate in 
broad terms the persons responsible for providing test summary 
information. PHMSA does not believe that the language proposed by 
Amazon and NRF defining ``subsequent distributor'' as those who possess 
and transfer title to lithium batteries and lithium battery products 
provides additional clarity as the phrase ``transfer title to'' is not 
understood in the context of the HMR. We note that the phrase 
``subsequent distributor'' is also used in section Sec.  178.2(c) of 
the HMR, applicable to package closure notifications, requiring 
manufacturers and subsequent distributors to notify each person to whom 
the package is transferred with appropriate closure information.
    In its comments, MDBTC stated that the proposed requirement for 
subsequent distributors to verify that a test summary document is 
available for all of the products it ships could be ``extremely 
burdensome'' and could potentially require the hiring of additional 
staff to verify the presence of a test summary. MDBTC suggests that a 
more reasonable approach would be for shippers of lithium cells and 
batteries to notify upstream distributors of test summary requirements 
but not to require the explicit verification for each shipment. MDBTCs 
comment contains no specific cost estimates, other than referencing the 
potential need to hire additional staff to manage the test summary 
requirements. PHMSA is cognizant of the costs associated with 
compliance such as creation of the test summary and activities related 
to subsequent distribution (see the ``Information Collection'' section 
of this rulemaking and the Regulatory Impact Analysis (RIA)), but notes 
that lithium batteries are already subject to the design testing 
requirements. Other than contacting the manufacturer, shippers 
currently have no way to confirm compliance with the UN design testing 
requirements. The proposed requirement provides a means for shippers to 
comply with the HMR when previously no such mechanism existed. 
Retrieving a test summary and ensuring it is made available to 
subsequent distributors will result in most instances in a one-time 
action and cost for each cell or battery design type offered for 
transportation (e.g., verifying the existence of the information and 
procuring a copy or creating a link for their own further use). It is 
expected to streamline what is currently a difficult process. While it 
is a requirement to make a test summary available for shipments of 
lithium cells or batteries, PHMSA does not intend to require a positive 
verification that the information has been received by each downstream 
customer. For instance, a distributor who has posted copies of test 
summaries or links to the appropriate test summaries on a website 
accessible to the next downstream distributor has made the test 
summaries available. There would be no additional burden on the initial 
distributor unless contact was initiated by the subsequent distributor 
who is unable to locate a test summary.
    MDBTC also submitted comments concerning who can make a request for 
a test summary, suggesting that requests should be limited to an actual 
distributor and not just anyone from the public or a person that is 
attempting to collect information not related to transport. MDBTC 
indicates that this limitation would be especially critical with 
respect to new product development and protecting proprietary 
information. While it is not envisioned that consumers of lithium 
batteries or products containing lithium batteries would generally 
request a test summary, if they are going to be offering the batteries 
back into transportation it would be necessary for them to have access 
to this information. The information required in the test summary was 
specifically crafted so as not to require proprietary information or 
information that would hinder product development.
    Amazon commented that PHMSA should clarify that if a subsequent 
distributor cannot obtain a test summary, but has a process in place to 
accurately classify lithium batteries, that distributor will not be 
subject to enforcement action for failure to provide a test summary for 
a specific product. PHMSA disagrees with the commenter. In accordance 
with Sec.  173.185(a)(1), each lithium cell or battery must be of the 
type proven to meet the criteria in part III, sub-section 38.3 of the 
UN Manual of Tests and Criteria. Therefore, a lithium cell or battery 
could not be classified unless the information provided on the test 
summary was available. If a distributor or other person in the 
transportation chain is classifying lithium cells or batteries, the 
information needed to develop a test summary must be available to that 
person.
    COSTHA compared the test summary requirements to those for safety 
data sheets (SDS) required by the Occupational Safety and Health 
Administration (OSHA) under their Hazard Communication Standard in 29 
CFR, Sec.  1910.1200. Manufacturers of hazardous chemicals are required 
to develop and make available safety data sheets that indicate the 
hazards associated with the hazardous chemicals that may be encountered 
in the workplace. COSTHA notes that SDSs are required to be provided by 
distributors to commercial customers, but not to non-commercial 
customers. COSTHA notes that test summary distributors would be 
required to provide the testing summary to a greater relative 
population than OSHA requires SDSs to be made available. PHMSA 
reiterates that the HMR require that shippers of lithium cells and 
batteries know that their batteries are of a tested type. If a non-
commercial customer does not intend to offer the battery or cell for

[[Page 27833]]

transportation there would be no requirement for them to further make 
the test summary available.
Requests for Exceptions for Button Cell Batteries
    DGAC and MDBTC requested PHMSA provide an exception from the 
requirement to provide a test summary for button cells installed in 
equipment or articles. The commenters noted that button cells installed 
in equipment are excepted from packaging and marking requirements under 
existing regulations. While lithium button cell batteries are excepted 
from certain requirements in the HMR and international standards, they 
are not excepted from the requirement to be of a tested type. The 
purpose of the test summary is provide information to downstream 
shippers that the lithium battery passed required tests and can be 
accepted or offered for transport. The primary benefit of the test 
summary is the increased visibility of the presence of lithium 
batteries particularly in products, and the ability of individuals in 
the transport chain to determine that that the lithium cells and 
batteries they offer for transport are of a tested type. If PHMSA was 
to accept the suggestions of MDBTC and DGAC to except equipment 
containing lithium button cell batteries from the test summary 
requirements, the benefits attributed to these provisions would not be 
gained. Excepting certain button cells and batteries from the test 
summary requirement does not enhance compliance and could lead to 
confusion on whether these cells and batteries are even subject to the 
design tests.
Requests for Clarification on the Docketed Guidance Document
    PHMSA drafted 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. In the NPRM, PHMSA 
requested comment on the usefulness of the guidance. PHMSA also 
requested comment to help improve its clarity and provide additional 
questions to add to the guidance. PHMSA received comments from COSTHA, 
MDBTC, PRBA, and the Chamber concerning the guidance document, which 
are categorized as follows:

 Must the test summary accompany the shipment
 Additional input on the development of the guidance document
 Devices containing different battery types
 Test summary availability
Must the Test Summary Accompany the Shipment
    In their comments, COSTHA and MDBTC provided general support for 
PHMSA's effort to issue a guidance document. COSTHA suggested that the 
HMR and guidance document should be amended to clarify that the test 
summary document is not required to be provided as documentation with 
each shipment, noting that PHMSA cannot prohibit industry from 
implementing its own procedures, such as requiring additional 
documentation be provided with a shipment. The guidance document 
available in the docket addressed this question. Specifically, on page 
5 of the guidance document, question and answer number 7. The question: 
``Must a manufacturer or distributor include the TS with product 
shipments?'' The answer: ``No, the product manufacturer or distributor 
would have to make the information available. This may be achieved by 
placing this information on a website or through alternative means.''
    PHMSA is not amending the HMR, as it believes the text in paragraph 
(a)(3) sufficiently addresses the commenters concern by indicating that 
the test summary must be made ``available upon request.'' The summary 
document does not need to physically accompany a shipment containing 
lithium batteries. PHMSA supports making the test summary available by 
electronic means and may revise the guidance document for 
clarification.
Additional Input on the Development of the Guidance Document
    COSTHA requested that PHMSA revise the guidance document once the 
final rule is issued and subsequently update it on a periodic basis 
with input from stakeholders. COSTHA also requested that PHMSA solicit 
additional input on the guidance document before the end of 2019 as 
experience gained both domestically and internationally could be 
captured in the guidance document for future reference. MDBTC requested 
that PHMSA revise the guidance document prior to issuing a final rule 
and consider soliciting additional input on the document. PHMSA does 
not believe an additional round of comments is necessary prior to 
publishing the final rule since comments were already received. PHMSA 
does intend to update the guidance to account for comments received in 
response to the NPRM. PHMSA also intends to update the guidance 
document as regulations change and when experience and feedback from 
stakeholders dictate a need.
Devices Containing Different Battery Types
    In its comments, MDBTC suggested that the guidance document should 
address situations where any number of different commercially available 
cells or batteries may be installed in a medical device. Specifically, 
the commenter indicated that while each battery supplier may have made 
the test summary available, it is a challenge to identify which battery 
is in the product, especially when it may be one of several similar 
batteries produced by different suppliers. PHMSA answered this question 
on page 5 of guidance document. The test summary requirement may be 
satisfied by using multiple, different test summaries for the batteries 
themselves, or by issuing a comprehensive test summary for the device 
that includes information for all of the batteries contained within the 
device.
Test Summary Availability
    PHMSA received comments from Amazon, DGAC, MDBTC, NRF, PRBA, and 
the Chamber concerning the timeframe in which the test summary must be 
provided following a request. The commenters asked for clarification as 
to what constitutes a ``reasonable time and location.'' NRF, PRBA, and 
the Chamber suggested PHMSA clarify that a ``reasonable'' time does not 
mean that the test summary must be made available immediately upon 
request. Amazon suggested that PHMSA should clarify that ``subsequent 
distributors'' will not be required to have test summaries on hand and 
will be afforded a reasonable amount of time to obtain one from the 
manufacturer. Amazon further suggested that PHMSA should clarify that 
it is the responsibility of the manufacturer to respond in a timely 
manner. PRBA and the Chamber suggested that PHMSA's final rule and 
guidance document should be consistent with the IATA's lithium battery 
guidance \11\ and industry test summary Q&A \12\ that states: ``Due to 
the large volume of lithium batteries and lithium battery powered 
products that are shipped daily, manufacturers and distributors should 
not be expected to immediately provide a test summary for every product 
they ship. Manufacturers and distributors should be provided a 
reasonable amount of time to provide

[[Page 27834]]

the required test summary.'' MDBTC recommended that PHMSA revise the 
text in paragraph Sec.  173.185(a)(3) from, ``must make available upon 
request at reasonable times and locations,'' to mirror the language in 
the UN Model Regulations, which reads ``shall make available.'' PHMSA 
agrees with the commenters that the test summary does not need to be 
made available immediately upon request, as that was not the intent of 
this requirement in the UN Model Regulations. As a result, PHMSA is 
amending the guidance document to clarify that manufacturers and 
distributors should make available the test summary in a reasonable 
amount of time but should not be expected to immediately provide a test 
summary for every product they ship. In addition, in this final rule, 
PHMSA is revising paragraph (a)(3) consistent with text in the 
international standards (a)(3) with the phrase ``must make available'' 
instead of ``must make available upon request at reasonable times and 
locations.'' The language proposed in the NPRM was an attempt to add 
clarity to the UN text by using similar language found in other 
sections of the HMR. Based on the comments received and upon further 
consideration, PHMSA believes aligning with the UN text will better 
reflect the intent of the regulation and avoid the possibility of 
imposing an undue burden.

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

    Section 173.185(b) requires lithium cells and batteries to be 
packed in inner packagings in such a manner as to prevent short 
circuits, including movement that could lead to short circuits. These 
inner packagings must be placed in an outer package that conforms to 
the requirements of part 178, subparts L and M, at the Packing Group II 
performance level. PHMSA is making several amendments to Sec.  
173.185(b) to update and clarify various provisions. PHMSA is amending 
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 
amendment minimizes the ambiguity in the current requirements and only 
prohibits movement that leads to damage within the package. PHMSA 
received a comment from MBDTC in support of this amendment.
    Further, PHMSA is amending Sec.  173.185(b)(3)(i) to specify that 
inner packagings must be separated from electrically conductive 
materials. This 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. In the 
NPRM, PHMSA had proposed adding ``except for transportation by 
passenger-carrying aircraft,'' to the beginning of Sec.  173.185(b)(5). 
This paragraph provides an exception from specification packaging for 
lithium batteries that weigh 12 kg (26.5 pounds) or more and have a 
strong, impact-resistant outer casing. This proposed addition is not 
being adopted, as the last sentence of this paragraph indicates that 
shipments in accordance with this paragraph are not permitted for 
transportation by passenger-carrying aircraft, and may be transported 
by cargo aircraft only if approved by the Associate Administrator.
    PHMSA is amending 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 clarifies 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 cells or 
batteries. Additionally, consistent with revisions to the ICAO 
Technical Instructions, PHMSA is adding 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. This action promotes consistency with the ICAO Technical 
Instructions and responds to a recommendation (A-16-001) from the 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(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 final rule, PHMSA is making 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 is 
amending Sec.  173.185(c)(2) to except equipment that is robust enough 
to protect lithium batteries from damage or short circuits from the 
requirement to be packaged. The current regulations provide an 
exception from the requirement for the package to be rigid, but 
otherwise require the equipment to be placed into a package. This 
amendment removes an unnecessary requirement to package otherwise 
robust equipment that protects lithium batteries from damage or short 
circuits. This amendment further aligns the HMR with the UN Model 
Regulations provisions found in special provision 188 for packaging of 
lithium cells, batteries, and equipment. PHMSA is removing the expired 
transitional provision in paragraph Sec.  173.185(c)(3)(ii), applicable 
to marking requirements. PHMSA is adding 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 (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 is 
amending 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 received a comment 
from MBDTC in support of the amendments that align the ``OVERPACK'' 
marking requirements. PHMSA is clarifying the limits for spare 
batteries in Sec.  173.185(c)(4)(vi) 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

[[Page 27835]]

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 received a comment from MBDTC in support of 
this amendment. PHMSA is adding a new Sec.  173.185(c)(4)(viii) 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).
    Section 173.185(d) of the HMR describes provisions for the 
transport of lithium cells and batteries for disposal or recycling. In 
the NPRM, PHMSA proposed to authorize the use of certain rigid large 
packagings to transport a single large battery or a single large item 
of equipment when transported for disposal or recycling. PRBA noted 
that the existing regulations for disposal or recycling of lithium 
batteries authorize strong outer packaging conforming to the 
requirements of Sec. Sec.  173.24 and 173.24a for batteries and 
equipment of all sizes and do not require the use of UN packaging. 
PHMSA agrees with the commenter. Lithium batteries and equipment 
transported for disposal or recycling are not required to be placed in 
UN packagings. PHMSA did not intend to implement more burdensome 
packaging requirements for large lithium batteries transported for 
disposal or recycling where packages prepared in accordance with the 
current requirements have a demonstrated record of safe transport. 
Accordingly, PHMSA is not adopting this proposal and amends Sec.  
173.185(d) to clarify this point. The use of UN specification 
packagings, including large packagings, will remain an option.
    Section 173.185(e) of the HMR sets forth provisions for the 
transport of low production and prototype lithium cells and batteries, 
including equipment. In this final rule, PHMSA is making 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 received a comment from MBDTC in support of this amendment. PHMSA 
is also making 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 is adding 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 provides 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) is renumbered and remain unchanged.
    Section 173.185(f) of the HMR describes the 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 is making an editorial amendment to Sec.  
173.185(f)(2) to specify that cushioning material must be electrically 
non-conductive, which harmonizes the HMR with the international 
standards. PHMSA is also amending 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 clarifies 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.
    ALPA commented that they did not see any proposed amendments for 
harmonization with three emergency amendments to the 2015-2016 ICAO 
Technical Instructions concerning the transport of lithium batteries by 
air. PHMSA published an interim final rule entitled ``Enhanced Safety 
Provisions for Lithium Batteries Transported by Aircraft'' on March 6, 
2019 [(HM-224I); 84 FR 8006], that amended and added multiple 
paragraphs in Sec.  173.185 incorporating these ICAO Technical 
Instructions amendments. The NPRM did not account for these amendments 
and additions. Therefore, in this final rule, we are revising this 
section consistent with the March 6, 2019 interim final rule. 
Specifically, we are including text added or revised in the March 6, 
2019 interim final rule in the following paragraphs: Sec.  
173.185(c)(1)(iii); (c)(4)(ii) through (vii); (c)(5); redesignated 
paragraph (g) as paragraph (h); and a new paragraph (g).
Section 173.218 Fish Meal or Fish Scrap
    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 \13\ 
that indicated that 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.
---------------------------------------------------------------------------

    \13\ https://www.unece.org/fileadmin/DAM/trans/doc/2016/dgac10c3/ST-SG-AC.10-C.3-2016-82e.pdf.
---------------------------------------------------------------------------

    In this final rule, PHMSA is amending 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 will reduce cost and add 
flexibility while maintaining an equivalent level of safety.
Section 173.220 Internal Combustion Engines, Vehicles, Machinery 
Containing Internal Combustion Engines, Battery-Powered Equipment or 
Machinery, Fuel Cell-Powered Equipment or Machinery
    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 both a flammable 
liquid and a

[[Page 27836]]

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 a flammable gas-powered vehicle. Consistent 
with the ICAO Technical Instructions, PHMSA is clarifying 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 final rule, PHMSA is making 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 
metal 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 Dangerous Goods in Equipment, Machinery or Apparatus
    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. An example of the current 
authorizations is for an article containing ``Heptanes UN 1206, Class 
3'' the HMR and ICAO Techinical Instructions authorize the use of UN 
3363 for machinery or apparatus up to a total net quantity of .5 L. For 
the same material the UN Model Regulations and the IMDG Code authorize 
1 L total net quantity of heptanes. The authorized limited quantity 
amounts in the IMDG Code and the UN Model Regulations generally align 
the ``methodology for determining limited quantities'' indicated in the 
Guiding Principles for the Development of the UN Model Regulations.\14\

    In a previous final rule published on March 5, 1999 [Docket No. 
RSPA-98-4185 (HM-215C); 64 FR 10742], 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 were 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 the IMDG Code, the new ``Articles containing hazardous 
materials, n.o.s.'' entries apply to articles that 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 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. The use of the new ``Articles containing hazardous 
materials, n.o.s.'' requires in all cases require competent authority 
approval prior to being offered for transport in accordance with the 
ICAO Technical Instructions.
    To more closely align with the UN Model Regulations and IMDG Code, 
for other than air transportation, PHMSA is increasing 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 remains unchanged for all 
modes of transport.
Section 173.224 Packaging and Control and Emergency Temperatures for 
Self-Reactive Materials
    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. Consistent with the UN

[[Page 27837]]

Model Regulations, in paragraph (b)(7), PHMSA is adding a new entry 
``Phosphorothioic acid, O-[(cyanophenyl methylene) azanyl] O,O-diethyl 
ester'' to the Self-Reactive Materials Table. In addition, consistent 
with the UN Model Regulations, a new ``Note 5'' assigned to this entry 
is added to the list following the table stating that this entry 
applies to the technical mixture in n-butanol within the specified 
concentration limits of the (Z) isomer.
    Paragraph (c) of this section prescribes requirements for new self-
reactive materials, formulations, and samples. In paragraph (c)(4), 
PHMSA is authorizing 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 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 adopted 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 United Nations SCOE on the Transport of Dangerous 
Goods showing the effectiveness of the packaging methods.
    Consistent with the UN Model Regulations, PHMSA is revising 
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 change allows materials that are authorized in bulk 
packagings to also be transported in appropriate non-bulk packagings.
Section 173.225 Packaging Requirements and Other Provisions for Organic 
Peroxides
    Section 173.225 prescribes packaging requirements and other 
provisions for organic peroxides. The Organic Peroxide Table in the UN 
Model Regulations is continually updated based on data submitted by 
governments and industry groups to account for new peroxides and 
formulations that have become commercially available. Consistent with 
revisions to the UN Model Regulations, PHMSA is revising 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.'' The table in paragraph (d)(4) currently titled 
``Maximum Quantity per Packaging/Package'' is amended to read ``Table 
to paragraph (d): Maximum Quantity per Packaging/Package.'' This change 
is being made in response to a request made during the publishing of 
the NPRM by the Federal Register to align with their requirements for 
table headings in regulations. The Organic Peroxide IBC Table in 
paragraph (e) is revised 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-1,4,7-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 
amending paragraphs (e) and (g) to authorize organic peroxides to 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 Articles Containing Hazardous Materials, n.o.s.
    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 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 new section authorizes 
a safe method to transport articles that may be too large to fit into 
typical packages. The packaging section 173.232 added in this final 
rule for the new proper shipping names for articles requires packaging 
at the Packing Group II performance level. Non-specification packaging, 
and transportation in an unpackaged manner or on pallets when the 
hazardous materials are afforded equivalent protection by the article 
in which they are contained, are also authorized. 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.
Section 173.301b Additional General Requirements for Shipment of UN 
Pressure Receptacles
    Section 173.301b describes additional requirements when shipping 
gases in UN pressure receptacles. In paragraph (c)(1), PHMSA is 
incorporating 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 Additional Requirements for Shipment of Liquefied 
Compressed Gases in UN Pressure Receptacles
    Section 173.304b contains additional requirements for the shipment 
of liquefied compressed gases in UN pressure receptacles. In this final 
rule, consistent with a change made in the 20th Revised Edition of the 
UN Model Regulations, PHMSA is amending 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 Additional Requirements for Excepted Packages 
Containing Class 7 (Radioactive) Materials
    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

[[Page 27838]]

shipping paper requirements found in the HMR. Amendment 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 
final rule, PHMSA is amending the DCM requirements in Sec.  176.30 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 final rule, 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 
an ocean bill of lading 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 
amendment provides for the conveyance of necessary information to the 
vessel operator for creation of the DCM.
Appendix I to Part 173
    PHMSA is also adding a new Appendix I to part 173, containing a 
flow chart for use with the calculation method for corrosive 
classification. Please see the section-by-section discussion for Sec.  
173.137 for further information on Appendix I to Part 173.

Part 174--Carriage by Rail

Section 174.50 Nonconforming or Leaking Packages
    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 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) 
Associate Administrator for Railroad Safety.
    Approvals issued by FRA's Associate Administrator for Railroad 
Safety are commonly referred to as One-Time Movement Approvals 
(OTMA).\15\ 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 is amending 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 U.S.-Canadian 
border.
---------------------------------------------------------------------------

    \15\ 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. 
PHMSA received comments from DGAC and Dow in support of the changes to 
Sec.  174.50 noting these amendments work to facilitate cross border 
trade.

Part 175--Carriage by Aircraft

Section 175.10 Exceptions for Passengers, Crewmembers, and Air 
Operators
    Section 175.10 specifies the conditions under which passengers, 
crew members, or an operator may carry hazardous materials aboard an 
aircraft. Consistent with revisions to the ICAO Technical Instructions, 
in this final rule, PHMSA is making several revisions to this section.
    PHMSA is revising 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 when carried on one's person.
    PHMSA is revising 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 is 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 is revising 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

[[Page 27839]]

than ``electrically powered'' articles. For lithium battery powered 
devices, quantity limits are 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 are revised to reference the provisions for spare batteries 
in paragraph (a)(18).
    PHMSA is revising paragraph (a)(15) by adding a new paragraph (vi) 
to separate and clarify the handling requirements applicable to each 
``non-spillable'' and ``dry sealed'' battery presently prescribed in 
paragraph (v). PHMSA is also adding a new paragraph (vii) to authorize 
passengers with restricted mobility to carry a spare non-spillable or 
dry sealed battery for their mobility aid. Prior to this rulemaking, 
spare lithium batteries were permitted for passengers with lithium 
battery-powered mobility aids; this was deemed acceptable for mobility 
aids equipped with non-spillable or dry sealed batteries. This action 
is consistent with the ICAO Technical Instructions.
    PHMSA is amending 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, and in these cases the 
batteries must be removed. Therefore, in this final rule, PHMSA is 
amending (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 is amending the provisions for carriage of portable 
electronic devices (PEDs) containing lithium batteries to address 
safety concerns requiring passengers to carry PEDs in checked baggage. 
Consistent with the ICAO Technical Instructions, Sec.  175.10(a)(18) is 
revised to require that when PEDs powered by lithium batteries are in 
checked baggage, they must be completely powered off and protected to 
prevent unintentional activation or damage. PHMSA received a comment 
from Yvonne Keller noting that in an October 18, 2018, final rule 
[Docket No. PHMSA-2015-0100 (HM-259) [83 FR 52878], PHMSA amended 
paragraph (a)(18)(i) to authorize passengers and crewmembers to carry 
on board an aircraft lithium metal battery-powered portable medical 
electronic devices and two spare batteries for those devices exceeding 
2 grams of lithium content per battery, but not exceeding 8 grams of 
lithium content per battery, with the approval of the operator. We 
agree that the NPRM did not account for this amendment. Therefore, in 
this final rule, we are revising this paragraph consistent with the 
earlier published final rule.
    PHMSA is revising 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 (DGP/26-
WP/42) submitted by the United States at the ICAO DGP/26 meeting, it 
was reported that even after the prohibition, 10 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.
    In this final rule, PHMSA is aligning 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.
    PHMSA is adding a new paragraph (a)(26) that amends 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 is 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 does 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.
    PHMSA received a comment from Alaska Airlines requesting that 
additional text be added to clarify that batteries must be removable 
without the use of any tool for baggage to be carried on, in the event 
the bag must subsequently be placed in the cargo compartment. However, 
in the NPRM, we proposed to align with the text of the ICAO Technical 
Instructions, which does not include this requirement. The requested 
language would, therefore, result in unalignment with the ICAO 
Technical Instructions and additional changes in existing practices in 
manufacturing and design of these types of bags.
Section 175.33 Shipping Paper and Information to the Pilot-in-Command
    Section 175.33 establishes requirements for shipping papers and for 
the notification of the pilot-in-command when hazardous materials are 
transported by aircraft. Consistent with

[[Page 27840]]

revisions to the ICAO Technical Instructions, in paragraph (a)(13)(i), 
PHMSA is including a requirement to indicate the airport at which the 
lithium batteries will be unloaded in 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 
existing authorization in paragraph (a)(12) to use a summary instead of 
the default information to the pilot in command for ``UN 1845, Carbon 
dioxide, solid (dry ice).'' Yevon Keller commented noting that the HM-
215O NPRM did not take into account recent changes to this section made 
in an October 18, 2018, final rule [Docket No. PHMSA-2015-0100 (HM-
259); 83 FR 52878]. The NPRM did not fully account for this amendment 
and, in this final rule, we are revising paragraphs (a)(12) and (13) to 
make them editorially consistent with the earlier published final rule.
    Additionally, in a recent interim final rule (IFR) published March 
6, 2019, [HM-224I; 84 FR 8006], PHMSA made revisions to some lithium 
battery requirements in the HMR.\16\ As part of the IFR, we made 
changes to Sec.  173.185(c) including redesignating paragraph 
(c)(4)(vi) as paragraph (c)(5). However, in the HM-224I IFR, we did not 
make a conforming amendment to Sec.  175.33, specifically Sec.  
175.33(a)(13)(iii), which continued to incorrectly reference Sec.  
173.185(c)(4)(vi). As such, the reference in Sec.  175.33(a)(13)(iii) 
should be to Sec.  173.185(c)(5), as this will correctly indicate that 
UN3480, UN3481, UN3090, and UN3091 materials prepared in accordance 
with Sec.  173.185(c)(5) are still required to appear on the 
information to the pilot-in-command. This HM-215O final rule makes that 
necessary editorial correction.

Section 175.78 Stowage Compatibility of Cargo
    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 15796], 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 final rule, 
PHMSA is adding an exception to the segregation requirement by 
including 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 requiring 
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) is reformatted 
into two paragraphs. A new paragraph (b)(2) is added to prescribe the 
segregation requirements applicable to lithium cells and batteries. The 
existing Segregation Table is revised by adding the necessary columns 
and rows representing hazard classes not presently in the Table. These 
changes to the Table 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 taking this action to promote 
consistency with the ICAO Technical Instructions and in response to a 
NTSB recommendation (A-16-001). The recommendation stemmed from NTSB's 
investigation of the July 28, 2011, in-flight fire and crash of Asiana 
Airlines Flight 991, which 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.
    PHMSA received two comments from COSTHA and Alaska Airlines in 
support of the segregation requirements. Alaska Airlines supports the 
changes to the segregation requirements and COSTHA supports the new 
Note 3 in Sec.  175.78 exempting ``UN3528'' from Division 5.1 
segregation requirements. Alaska Airlines asked if it was an oversight 
that PHMSA did not propose to amend Sec.  175.310(c)(1)(ii) to include 
similar prohibitions on shipping lithium metal and lithium ion 
batteries with flammable liquids, which authorizes transportation of 
flammable liquid fuel by passenger and cargo aircraft when other means 
of transportation are impracticable. Shipments made in accordance with 
Sec.  175.310 may vary from the packaging references and quantity 
limits listed in Columns 7, 8, and 9 of the HMT. PHMSA did not propose 
or intend to propose amendments to Sec.  175.310 in the NPRM. As no 
amendments were proposed to this section or these provisions, we are 
not amending the requirements in this section in this final rule. The 
FAA and PHMSA have agreed to look at the issue further and any 
potential future rulemaking action would afford stakeholders the 
opportunity to review and provide comments.

Part 176--Carriage by Vessel

Section 176.30 Dangerous Cargo Manifest
    Section 176.30 prescribes requirements for DCMs, lists, or stowage 
plans required to be carried aboard vessels transporting hazardous 
materials. For consistency with the IMDG Code in this final rule, PHMSA 
is adding 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 is required to be entered on the DCM, 
list, or stowage plan carried aboard the vessel.
Section 176.84 Other Requirements for Stowage, Cargo Handling, and 
Segregation for Cargo Vessels and Passenger Vessels
    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 separated 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

[[Page 27841]]

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 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 final rule, we are adding 
new stowage provisions that clarify what segregation requirements apply 
to shipments of uranium hexafluoride.
    PHMSA is adding a new stowage provision 151 and assigning it to the 
UN 2977 and UN 2978 uranium hexafluoride entries. This new stowage 
provision requires 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 is adding a new stowage provision 152 and assigning it to UN 
3507, Uranium hexafluoride, radioactive material, excepted package. 
This new stowage provision requires segregation 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 
is adding a new stowage provision 153 and assigning it to the UN 2977 
and UN 2978 uranium hexafluoride HMT entries. This 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 is adding a 
new stowage provision 154 and assigning it to the NA 0124, NA 0494, UN 
0494, and UN 0124 jet perforating gun HMT entries. This 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--Specifications for Packagings

Section 178.71 Specifications for UN Pressure Receptacles
    Section 178.71 prescribes specifications for UN pressure 
receptacles. Consistent with the UN Model Regulations, PHMSA is 
amending paragraphs (d)(2), (f), (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 adding a phase out date for ISO 13340:2001, 
which is authorized for valves manufactured until December 31, 2020, 
and incorporating 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 requirements have been 
incorporated into ISO 11118:2015. In paragraph (f), PHMSA is amending 
the title of the paragraph to include pressure drums and adding 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 Model 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.\17\ Therefore, PHMSA 
is authorizing the same deviation from the ISO standard in paragraph 
(f).
---------------------------------------------------------------------------

    \17\ https://www.unece.org/fileadmin/DAM/trans/doc/2015/dgac10c3/UN-SCETDG-48-INF49_e_.pdf.
---------------------------------------------------------------------------

    In addition, in paragraph (i), PHMSA is adding a phase out date for 
ISO 11118:1999 ``Gas Cylinders for Non-refillable Metallic Gas 
Cylinders,'' which is authorized until December 31, 2020, and replacing 
it with the new standard, ISO 11118:2015. In paragraph (j), PHMSA is 
adding a phase out date for ISO 111120:1999, ``Gas Cylinders for 
Refillable Seamless Steel Tubes,'' which is authorized until December 
31, 2022, and replacing 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 multi-element gas 
containers (MEGCs). In paragraph (d)(3)(v), PHMSA is adding a phase out 
date for ISO 11120:1999, which is authorized for construction and 
testing of receptacles of MEGCs until December 31, 2022, and 
authorizing 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.
Section 178.601 General Requirements
    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 final rule, PHMSA is requiring in 
paragraph (l)(2)(viii) that the test report for plastic packagings that 
are subject to the hydraulic pressure test 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. PHMSA received a comment from RIPA supporting the 
requirement.
Section 178.801 General Requirements
    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 final rule, PHMSA is 
requiring 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

[[Page 27842]]

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. PHMSA 
received a comment from RIPA supporting the requirement.
Section 178.810 Drop Test
    Section 178.810 prescribes the requirements for an IBC drop test. 
In the NPRM, we proposed to amend paragraph (c)(1), to clarify that the 
same IBC or a different IBC of the same design type may be utilized for 
the required drop tests. PHMSA received a comment from Frits Wybenga 
noting that IBCs exceeding 450 L (0.45 cubic meters) capacity only 
require one drop test and that our proposed language could confuse 
users. PHMSA agrees and has determined that (c)(2), addressing IBC 
design types with a capacity of 0.45 cubic meters or less is the most 
appropriate paragraph for this provision. As such, we are amending 
paragraph (c)(2).

Part 180--Continuing Qualification and Maintenance of Packagings

Section 180.207 Requirements for Requalification of UN Pressure 
Receptacles
    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, to reduce the need for special permits, and to facilitate 
cross-border transportation of these cylinders. Section Sec.  
171.12(a)(4) permits 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 provided that a shipper may use either a DOT 
specification cylinder or a TC cylinder, as appropriate. In this final 
rule, PHMSA is clarifying the amendments in HM-215N and allowing for 
the requalification of ``CAN'' marked UN cylinders in the United 
States.
    In the NPRM, PHMSA proposed that 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. PHMSA 
received a comment from Transport Canada stating that it disagrees that 
UN cylinders marked with the letters ``CAN'' must comply with the U.S. 
manufacturing and approval requirements in Sec. Sec.  178.69, 178.70, 
and 178.71, as the cylinders are manufactured to comply with the TDG 
Regulations. Transport Canada recommended that consistent with the 
reciprocity provisions for TC cylinders added in the HM-215N final 
rule, UN cylinders marked with the letters ``CAN'' be requalified and 
marked by a facility registered by Transport Canada in accordance with 
the Transport Canada TDG Regulations. PHMSA agrees with the commenter 
that allowing this method of requalification is consistent with 
previous amendments concerning requalification of Canadian pressure 
vessels using TDG Regulations, promotes U.S. and Canadian regulatory 
reciprocity and facilitates international trade. In this final rule, 
PHMSA is revising paragraph (a)(2) per the recommendation from 
Transport Canada.
    Consistent with changes to the UN Model Regulations, PHMSA is 
revising paragraph (d)(1) to incorporate ISO 16148:2016, which 
addresses the requalification of seamless steel cylinders and tubes. 
This addition allows 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 16148:2016. Non-
destructive test methods in this ISO standard have been updated to 
provide a method for evaluating the significance of acoustic emission 
examination identifed emission sources. This standard specifies the 
ultrasonic examination method as a follow-up procedure to evaluate the 
significance of sources identified through acoustic emissions 
examinations. Additionally, in paragraph (d)(4), PHMSA is adding a 
phase out date for 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 is adding 
new paragraph (d)(6) to incorporate inspection and maintenance 
requirements for cylinder valves 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 references to additional documents for steel and aluminum-
alloy liner materials; and an update of some photographs to provide 
sharper examples of damage.
Section 180.217 Requalification Requirements for MEGCs
    Section 180.217 contains requalification requirements for MEGCs. 
PHMSA received a comment from Transport Canada that the HM-215N final 
rule did not extend reciprocity to the requalification of MEGCs 
performed by facilities registered with Transport Canada. The commenter 
noted that having mutual recognition for cylinder requalification was 
one of the main goals of the U.S.-Canada Regulatory Cooperation 
Council. PHMSA agrees that the ability to requalify MEGC's is 
consistent with previous amendments concerning pressure vessels and 
promotes U.S. and Canadian regulatory reciprocity and facilitates 
international trade. In this final rule PHMSA is revising paragraph (a) 
by authorizing MEGCs to be requalified by a facility registered by 
Transport Canada in accordance with the Transport Canada TDG 
Regulations.

VI. Regulatory Analyses and Notices

A. Statutory/Legal Authority for This Final Rule

    This final rule amends the HMR 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. This final rule is 
published under the statutory authority of Federal hazardous materials 
transportation law (Federal hazmat 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. Additionally, 49 U.S.C. 5120(b) authorizes the 
Secretary to ensure that, to the extent practicable, regulations 
governing the transportation of hazardous materials in commerce are

[[Page 27843]]

consistent with standards adopted by international authorities. The 
Secretary's authority is delegated to PHMSA at 49 CFR 1.97.

B. Executive Order 12866 and DOT Regulatory Policies and Procedures

    This final rule is not considered a significant regulatory action 
under section 3(f) of Executive Order (E.O.) 12866, Regulatory Planning 
and Review, 58 FR 51735 and, therefore, was not formally reviewed by 
the Office of Management and Budget. This final rule is not considered 
a significant rule under the Department of Transportation's Policies 
and Procedures for Rulemakings (DOT Order 2100.6; Dec. 20, 2018).
    E.O. 12866 requires agencies to design regulations ``in the most 
cost-effective manner,'' to make a ``reasoned determination that the 
benefits of the intended regulation justify its costs,'' and to develop 
regulations that ``impose the least burden on society.'' In this final 
rule, PHMSA accomplishes the directives of E.O. 12866 by harmonizing 
the HMR with widely used consensus international standards to address 
specific safety concerns, reduce regulatory burdens, and facilitate 
international trade. Such alignment promotes international trade 
through standardization, facilitates domestic transportation and 
reduces regulatory burden by using a single set of guiding principles 
worldwide.
    Overall, the issues discussed in this final rule promote the 
continued safe transportation of hazardous materials while producing 
net cost savings. Cost savings are derived from generalized 
harmonization effects (such as avoided costs of compliance) and the 
specific provisions related to corrosivity classification that adds 
alternative packing group assignment methods to classify corrosive 
mixtures without conducting physical testing. Details on the estimated 
cost savings and benefits of this final rule can be found in the rule's 
Regulatory Impact Analysis (RIA), which is available in the public 
docket.
    Based on the discussions of benefits and costs provided above, 
PHMSA estimates discounted net cost savings at a 3 percent discount 
rate of approximately $93,000-$2.2 million per year and at a 7 percent 
discount rate of approximately $55,000-$2.1 million per year. Please 
see the complete RIA for a more detailed analysis of the costs and 
benefits of this final rule.

C. Executive Order 13771

    This final rule is considered an E.O. 13771 deregulatory action. 
Details on the estimated cost savings of this final rule are discussed 
in the rule's RIA, which has been uploaded to the docket.

D. Executive Order 13132

    This final rule was analyzed in accordance with the principles and 
criteria contained in E.O. 13132, Federalism, 64 FR 43255. E.O. 13132 
requires agencies to assure meaningful and timely input by State and 
local officials in the development of regulatory policies that may have 
``substantial direct effects on the States, on the relationship between 
the national government and the States, or on the distribution of power 
and responsibilities among the various levels of government.'' The 
regulatory changes in this final rule may preempt State, local, and 
Indian tribe requirements but do not have substantial direct effects on 
the States, the relationship between the national government and the 
States, or the distribution of power and responsibilities among the 
various levels of government. Therefore, the consultation and funding 
requirements of Executive Order 13132 do not apply.
    The Federal hazardous materials transportation law contains an 
express preemption provision, 49 U.S.C. 5125(b), that preempts State, 
local, and Indian tribe requirements on certain covered subjects, 
unless the non-Federal requirements are ``substantively the same'' as 
the Federal requirements:
    (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 final rule addresses covered subject items (1), (2), (3), and 
(5) above. Therefore, this final rule preempts State, local, or tribal 
requirements concerning these subjects unless the non-Federal 
requirements are ``substantively the same'' as the Federal 
requirements. PHMSA received no comments on the NPRM regarding the 
effect of the adoption of the specific proposals on State, local or 
tribal governments.

E. Executive Order 13175

    This final rule was analyzed in accordance with the principles and 
criteria contained in E.O. 13175, Consultation and Coordination with 
Indian Tribal Governments, 65 FR 67249. E.O. 13175 requires agencies to 
assure meaningful and timely input from Indian tribal government 
representatives in the development of rules that significantly or 
uniquely affect Tribal communities by imposing ``substantial direct 
compliance costs'' or ``substantial direct effects'' on such 
communities or the relationship and distribution of power between the 
Federal government and Indian tribes. This final rule is likely to 
affect 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. It does 
not impose substantial direct compliance costs and does not have 
substantial direct effects on Native American tribal governments. 
Therefore, the funding and consultation requirements of E.O. 13175 do 
not apply. Further, PHMSA did not receive comments on the tribal 
implications of the rulemaking.

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

    The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires an 
agency to review regulations to assess its 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. 
E.O. 13272, ``Proper Consideration of Small Entities in Agency 
Rulemaking, 68 FR 7990,'' requires agencies to establish procedures and 
policies to promote compliance with the Regulatory Flexibility Act and 
to ``thoroughly review draft rules to assess and take appropriate 
account of the potential impact'' of the rules on small businesses, 
governmental jurisdictions and small organizations. This rule was 
developed in accordance with this E.O. and DOT's procedures and 
policies (DOT Order 2100.6) to promote compliance with the Regulatory 
Flexibility Act and to ensure that the potential impacts of a 
regulatory action on small entities were properly considered.
    Section 603(b) of the Regulatory Flexibility Act requires an 
analysis of the possible impact of the rule on small entities, 
including the need for the rule, the description of the action, the 
identification of potentially affected

[[Page 27844]]

small entities, the reporting and recordkeeping requirements, the 
related Federal rules and regulations, and the alternative proposals 
considered.
    PHMSA expects the amendments in this rule to result in overall net 
cost savings and ease the regulatory compliance burden for shippers 
engaged in domestic and international commerce, including trans-border 
shipments within North America. Additionally, the changes effected by 
this rule 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 have a significant economic impact on a substantial number of 
small entities. However, PHMSA solicited comments in the NPRM on the 
anticipated economic impacts to small entities. Comments from Amazon 
and NRF to the NPRM indicated that the requirement to prepare a test 
summary and the subsequent distribution to others in the supply chain 
for all lithium cells and batteries manufactured would have a 
disproportionate impact on small businesses. While the commenters 
provided no quantitative context, PHMSA estimated the burden on 
manufacturers and subsequent distributors for the lithium cell and 
battery test summary requirement in the SBA below to address this 
issue. Such analysis for this final rule is as follows, supplemented by 
the analysis contained in the RIA, which can be found in the docket for 
this rulemaking:
1. Need for the Final Rule
    This final rule adopts the conditional use of international 
standards, and where appropriate, harmonizes domestic transportation 
requirements for hazardous materials with those found in the applicable 
international standards. This harmonization promotes compliance cost 
savings, process efficiencies/time savings, reduced potential property, 
health and environmental damages, and increased trade flows/reduction 
in barriers to trade.
    The benefits from the adoption of the amendments include enhanced 
transportation safety resulting from the consistency of domestic and 
international hazard communication and continued access to foreign 
markets by U.S. manufacturers and other businesses that are 
transporters of hazardous materials.
2. Description of the Action
    This final rule facilitates the transportation of hazardous 
materials in international commerce by providing consistency with 
international standards. The rule will align the HMR 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.
3. Identification of Potentially Affected Small Entities
    The term ``small entities,'' as described in 5 U.S.C. 601, 
comprises small businesses and not-for-profit organizations that are 
independently owned and operated and are not dominant in their fields 
and governmental jurisdictions with populations of less than 50,000. 
The amendments considered here are likely to affect 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 noted above, PHMSA expects that these amendments will not have a 
significant economic impact on a substantial number of small entities. 
However, to address comments to the NPRM indicating that the 
requirement to create a test summary for lithium cells and batteries 
and for subsequent distributors to make this information available to 
others in the supply chain would have a disproportionate impact on 
small businesses, PHMSA estimated the burden on manufacturers and 
subsequent distributors for the lithium cells and batteries test 
summary requirements. PHMSA identified approximately 3,700 small 
entities that may be impacted by the lithium cell and battery test 
summary requirements. PHMSA examined the entities in NAICS codes for 
battery retailers, wholesalers, and merchants and identified the 
percentage of entities in each NAICS industry that are involved in 
distributing batteries based on the sub-NAICS product series 
information provided in the 2012 Economic Census by Industry. PHMSA 
assumed that product manufacturers would include 27.9 percent of 
Electrical Apparatus and Equipment, Wiring Supplies, and Related 
Equipment Merchant Wholesalers (NAICS 423610), 50 percent of Power-
Driven Handtool Manufacturing (NAICS 333991) and 100 percent of 
Electronic Computer Manufacturing (NAICS 334111) and Radio and 
Television Broadcasting and Wireless Communications Equipment 
Manufacturing (NAICS 334220). Finally, PHMSA determined that retailers 
would need to make the test summary document available to customers. 
PHMSA assessed that retailers would predominantly fall within the All 
Other Miscellaneous Store Retailers (NAICS 453998) and that 2.2 percent 
of all firms in this sector may be affected. Then PHMSA multiplied this 
percent by the more recent U.S. Census Bureau Statistics of U.S. 
Businesses (SUSB) 2016 \18\ to estimate the total number of potentially 
impacted respondents. Please see the RIA submitted to the docket for 
this rulemaking for a more detailed analysis of these small entities. 
As a result of our analysis on the impacts test summary document 
requirements will have on small buisnesses, PHMSA believes that 
although some small businesses will be directly impacted, particular 
firms and their associated industries are unlikely to experience 
significant (i.e., greater than 1 percent) impacts.

---------------------------------------------------------------------------
 Reporting and recordkeeping requirements

    Reporting and recordkeeping requirements are discussed in detail in 
the RIA submitted to the docket for this rulemaking and the ``Paperwork 
Reduction Act'' section of this rulemaking. These requirements will 
apply to all regulated entities, including small entities.
4. Related Federal Rules and Regulations
    PHMSA is unaware of any Federal rules and regulations that are 
substantially similar to the requirements in this final rule.
5. Alternative Proposals for Small Business
    The Regulatory Flexibility Act directs agencies to establish 
exceptions and differing compliance standards for small businesses, 
where it is possible to do so and still meet the objectives of 
applicable regulatory statutes. PHMSA does not believe there are 
alternative compliance standards for small businesses that still meet 
the objectives of these regulatory statutes.
    Excepting small entities from the test summary requirements would

manufacturers and distributors of lithium cells and batteries and 
equipment powered by cells and batteries to make available a ``test 
summary'' as specified in the UN Manual of Tests and Criteria, Sixth 
Revised Edition, Amendment 1, Part III, sub-section 38.3, paragraph 
38.3.5. Fully harmonizing the test summary requirements allows 
traceability and accountability of those involved in the lithium cells 
and batteries transport chain, including small entities, thereby 
ensuring that lithium cell and battery designs offered for transport 
contain specific information on the required UN tests. In addition, it 
allows those in the distribution chain, including small entities, to 
more easily identify non-counterfeit products by providing confirmation 
to users that the battery is from a legitimate and compliant source and 
that they are receiving, and potentially reoffering for transportation, 
a battery that is of a tested and approved type. PHMSA believes this 
may generate safety benefits if counterfeit batteries are more likely 
to rupture, catch fire or otherwise increase the risk of a dangerous 
incident.
6. Conclusion
    PHMSA conducted a Small Business Analysis (SBA) for this final rule 
(see RIA in the docket for this rulemaking). Based on this analysis, 
PHMSA believes that some small businesses will be directly impacted by 
the lithium cells and batteries test summary requirement; however, 
PHMSA found particular firms and their associated industries are 
unlikely to experience significant impacts. In particular, PHMSA 
demonstrated that the average annual cost of the test summary document 
is less than one percent of the average annual revenue for each NAICS 
revenue category for which data was available. Please see the RIA for a 
more detailed analysis.
    Comments from Amazon and NRF to the NPRM indicated that the 
requirement that subsequent distributors produce a test summary would 
have disproportionate impact on small businesses. While the commenters 
provided no quantitative data, PHMSA did review the initial estimation 
of burden on subsequent distributors in the SBA for the lithium cells 
and batteries test summary requirement to address this issue. Please 
see the RIA for this rulemaking in the docket.
    Many companies, including small entities, will realize overall 
economic benefits as a result of the amendments in the final rule. As 
previously discussed, PHMSA expects the amendments in this rule to 
result in a net cost savings and ease the regulatory compliance burden 
for shippers engaged in domestic and international commerce, including 
trans-border shipments within North America. Additionally, the changes 
effected by this final rule will relieve U.S. companies, including 
small entities, competing in foreign markets, from the burden of 
complying with a dual system of regulations. Consequently, PHMSA 
certifies that this final rule does not have a significant economic 
impact on a substantial number of small entities.

G. Paperwork Reduction Act

    PHMSA has analyzed this rule in accordance with the Paperwork 
Reduction Act of 1995 (PRA) (Pub. L. 96-511). PHMSA is revising the 
approved information collections under the following 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 anticipates that this final rule 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 already 
required 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 33.33 hours. At a mean hourly wage of 
$38.77,\19\ it is estimated to increase annual salary costs by 
$1,292.34. PHMSA does not anticipate this requirement will affect out-
of-pocket expenses.

    PHMSA estimates that this rulemaking 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 January 
1, 2008. Lithium cell or battery manufacturers will need to create a 
test summary for all 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 final rule 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.
    In the NPRM, PHMSA estimated the requirement to create a test 
summary for lithium cells and batteries manufactured after June 30, 
2003 would result in an overall increase in burden. In response to 
comments received in the NPRM, discussed in more detail above, PHMSA is 
adopting a requirement to require a test summary for lithium cells and 
batteries manufactured after January 1, 2008. This will result in less 
lithium cells and batteries requiring test summaries than estimated in 
the NPRM. Cells and batteries that ceased being manufactured between 
June 30, 2003 and December 31, 2007 would not require a test summary or 
subsequent distribution to downstream distributors. In addition, PHMSA 
is changing the implementation date for this provision from year 2020 
to year 2022. During the voluntary compliance period of the final rule, 
lithium cell or battery

[[Page 27846]]

manufacturers will need to create a test summary for all of the 
previously manufactured lithium cells and batteries; after the final 
rule goes into effect, lithium cell or battery manufacturers will need 
to create a test summary for newly manufactured lithium cells and 
batteries. Therefore, PHMSA is adding two information collections 
associated with this OMB Control Number--one for lithium cells and 
batteries manufactured from January 1, 2008 to a final rule 
implementation date and one accounting for the annual manufacture of 
new lithium cells and batteries after a final rule compliance date.
    In the preliminary RIA, PHMSA identified 73 domestic lithium cell 
or battery manufacturers per U.S. Census' Annual Survey of Manufactures 
(NAICS code 335912).\20\ PHMSA looked at publicly available company 
websites for 35 domestic companies known to manufacture lithium cells 
or batteries.\21\ 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 cell and battery design types 
currently manufactured by these domestic manufacturers is 32. PHMSA 
estimated in the preliminary RIA 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).\22\ Therefore, 5,840 new test 
summaries must be created for lithium cells or batteries (73 
manufacturers x 80 lithium cells or batteries).

    \21\ Only 35 of the identified domestic lithium cell and battery 
manufacturers had websites with usable information containing 
battery or cell design types.
    \22\ 2.5 is a multiplier to account for the uncertainties noted 
in the RIA submitted to the docket for this rulemaking.
---------------------------------------------------------------------------

    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 completed sample test 
summary documents using 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 expected 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 estimated in the preliminary RIA 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 estimated in the preliminary RIA a mean hourly wage 
rate of approximately $67.03 \23\ for a total of $195,727.76 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.

    \23\ Occupation labor rates based on 2017 Occupational and 
Employment Statistics Survey (OES) for ``Electrical Engineers (17-
2070)'' in the Other Electrical Equipment and Component 
Manufacturing industry. The hourly mean wage for this occupation 
($45.78) is adjusted to reflect the total costs of employee 
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).
---------------------------------------------------------------------------

    As noted above, comments received to the NPRM indicated that 
applying the test summary requirements to batteries manufactured after 
June 30, 2003 is too long of a time frame to include. For the reasons 
explained above, PHMSA is changing this provision to require a test 
summary for lithium cells and batteries manufactured after January 1, 
2008. Therefore, cells and batteries that ceased being manufactured 
between June 30, 2003 and December 31, 2007 will not require a test 
summary or subsequent distribution to downstream distributors. No 
comments were received regarding our estimation of the number of 
domestic cell and battery manufacturers, the number of design types 
they make, or the time it takes to develop a test summary. Therefore, 
PHMSA is utilizing the preliminary RIA figures for these items and 
adjusting to account for the final rule applicability date change.
    This final rule extends the applicability date for this provision 
from year 2020 to year 2022. This increases the compliance time from 
one year to two years, which results in a reduction of the costs 
estimated with this provision at the NPRM stage. In the preliminary 
RIA, PHMSA estimated 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 and that 5,840 new test 
summaries would need to be created for lithium cells or batteries. To 
account for the change in not requiring the creation and distribution 
of test summaries from batteries and cells manufactured between June 
30, 2003 to January 1, 2008, PHMSA is reducing the uncertainty 
multiplier utilized to determine the number of test summaries required 
from 2.5 to 2.0. Based on the uncertainties noted below, PHMSA 
estimates the number of batteries and cells currently manufactured--
that were tested between January 1, 2008 and the estimated compliance 
date of a final rule--by each domestic lithium cell or battery 
manufacture to be 64 per manufacturer (32 lithium cells or batteries 
manufactured x 2). This change results in a reduction in the number of 
test summaries required from 5,840 to 4,672 (32 lithium cells or 
batteries per manufacturer x 2 x 73 manufacturers). Therefore, PHMSA 
estimates that this requirement will increase the total burden by 2,336 
hours (4,672 test reports x 30 minutes).
    Uncertainties:

--Information on company websites generally only accounts for battery 
and cells that are currently actively offered for sale by the company. 
The test summary requirement would be applicable to all batteries and 
cells manufactured after January 1, 2008. Thus, the information 
available on 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.
--PHMSA identified 14 domestic lithium battery cell and battery 
manufacturers with usable information on design types on their websites 
as a representative sample. Companies that did not provide individual 
product listings on their websites were not included in the above 
calculations. The companies that were researched constitute a 
representative sample of lithium cell and battery manufacturers because 
they make cells and batteries for automobiles, military, medical, and 
portable electronic devices.

    To calculate the total salary cost for preparing new test 
summaries, PHMSA estimates in this final analysis a mean

[[Page 27847]]

hourly wage rate of approximately $67.0278,\24\ for a total of $156,577 
in salary cost, reduced from the total salary cost estimated at the 
NPRM stage of $195,721.23. Because there is a two year compliance date, 
PHMSA estimates that half of the test summary will be created in the 
first year. Therefore, to estimate first year burden, PHMSA divided the 
estimated number of responses by 2, resulting in half of the estimated 
annual burden hours and costs.

    \24\ Occupation labor rates based on 2017 Occupational and 
Employment Statistics Survey (OES) for ``Electrical Engineers (17-
2070)'' in the Other Electrical Equipment and Component 
Manufacturing industry. The hourly mean wage for this occupation 
($45.78) is adjusted to reflect the total costs of employee 
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 
$67.0278 = wage rate $45.78/wage % of total compensation 68.3%).

    Annual Increase in Number of Respondents: 73.
    Annual Increase in Number of Responses: 2,336.
    Annual Increase in Burden Hours: 1,168.
    Annual Increase in Salary Costs: $78,288.
    Annual Increase in Burden Costs: $0.
    This test summary requirement is also anticipated to increase the 
burden for recordkeeping requirements. As detailed in the new 
requirements, the test summary must be made available for every cell or 
battery design type, 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 choose the alternative 
that requires the least amount of recordkeeping burden possible. PHMSA 
believes the least burdensome method is to make the test summaries 
available on company websites by utilizing links to battery 
manufacturer websites where the information is made available. This 
method presumes that cell and battery manufacturers and distributors 
maintain infrastructure such as websites that have storage capacity to 
link to these reports.
    To estimate the burden hours and salary costs for this 
recordkeeping requirement, in the preliminary RIA, 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. PHMSA 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 estimated 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. PHMSA further 
estimated that product manufacturers utilize cells and batteries from 
an average of five different cell or battery manufacturers. Lastly, 
PHMSA estimated 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.
    As noted above, to account for the change in requiring creation and 
distribution of test summaries from batteries and cells manufactured 
June 30, 2003 to January 1, 2008, PHMSA is reducing the uncertainty 
multiplier utilized in the preliminary RIA to determine the number of 
test summaries required from 2.5 to 2.0. This change results in a 
reduction in the number of test summaries required from 5,840 to 4,672. 
See below the breakdown of the lithium cell and battery supply chain, 
the number of estimated entities, and the number of estimated test 
summaries required to be made available.

    PHMSA estimated in the preliminary RIA that ensuring test summaries 
are available will take 5 minutes per report utilizing the electronic 
methods noted above.\25\ This results in a total recordkeeping 
requirement of 3,363.33 annual burden hours (40,360 responses x 5 
minutes). At an estimated mean hourly annual salary wage of 
approximately $67.03 \26\ PHMSA estimates the salary cost for 
recordkeeping will increase by $225,444.01. PHMSA does not estimate 
that this will result in a increase in any out-of-pocket expenses.

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

    Comments to the NPRM from Amazon indicated that the requirement 
that subsequent distributors produce a test summary would have 
disproportionate impact on small businesses. While the commenter 
provided no quantitative information, PHMSA has reviewed our initial 
estimation of burden on subsequent distributors (both large and small) 
and revised our estimated impact. The initial review of impacts 
adequately accounts for the time required to ensure a test summary 
exists in the least burdensome method of compliance noted above. 
However, we are amending our estimated impact to account for additional 
time that may be needed to verify that appropriate information exists, 
either after initial procurement of the document or link and 
verification on request of subsequent downstream distributors. This 
additional time will add another 2 minutes to each test summary 
increasing the annual burden hours from 5 minutes a response to 7 
minutes

4,572.4 hours (39,192 responses x 7 minutes). At an estimated mean 
hourly wage of $67.03,\28\ PHMSA estimates the total cost for 
recordkeeping increases to $306,478 from the preliminary estimate with 
recordkeeping requirement of $225,437. To estimate the annual increases 
in the number of respondents, responses and in the burden hours and 
costs, PHMSA divides the total estimated burden by 2, the number of 
years of voluntary compliance with this provision due to the change in 
the implementation date as noted above.

    PHMSA is adding 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 relation to the number of respondents and burden hours 
currently associated with this information collection. The revisions 
include: A new requirement to indicate ``TEMPERATURE CONTROLLED'' on a 
shipping paper if not already indicated in the proper shipping name, 
when appropriate; removing 1-dodecene to the list of marine pollutants 
in Appendix B to Sec.  172.101; a new requirement to include the UN 
identification number for the material being offered, the name and 
address of the consignor and consignee, and a container packing 
certificate on a Dangerous Cargo Manifest for excepted packages 
containing Class 7 materials transported by vessel.
OMB Control Number 2137-0557, ``Approvals for Hazardous Materials''
    We anticipate this final rule will increase the overall burden for 
this information collection request. PHMSA is adding special provision 
347 to four explosive Division 1.4S 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). Please see the 
RIA submitted to the docket for this rulemaking for more information. 
At a mean hourly wage of $79.06,\29\ PHMSA estimates an increase of

    PHMSA is also adding 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 relation 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 from 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.
    OMB Control Number 2137-0572, as currently approved by OMB, is 
divided into five Information Collections (IC), one of which is 
identified as Testing Requirements for Non-Bulk Packaging. This IC is 
specific to the requirements in Sec.  178.601 for creating the test 
report. As mentioned in the approved supporting statement (see 
reginfo.gov), PHMSA has estimated that 5,000 persons will complete this 
requirement based on historic stakeholder feedback. It's important to 
note, that this IC is not specific to each packaging type, instead it 
is for all persons testing non-bulk packaging.
    In the approved IC, PHMSA estimated a total of 2 hours for the 
creation of each test report. Because the change in requirement is only 
for a small subset of the 5,000 respondents, PHMSA estimated an 
increase of 1 minute to determine the appropriate water temperature and 
note in the existing test report. This accounts for a reasonable 
average increase for all persons completing the test report. At a mean 
hourly wage of $68.58,\30\ it is estimated to increase annual salary 
costs of $17,145 (5,000 x 3 = 15,000 responses x 1 min/= 15,000 
minutes) (15,000 minutes/60 = 250 hours x $68.58 = $17,145). PHMSA does 
not anticipate this requirement to affect out-of-pocket expenses.

Warehousing industry. The hourly mean wage for this occupation 
($48.43) 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

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 final rule 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,\31\ this reduction is expected to save 
$35,181.54 in salary cost. PHMSA estimates there is no reduction in 
out-of-pocket expenses.

H. Regulation Identifier Number (RIN)

    A 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

    The Unfunded Mandates Reform Act (UMRA) of 1995, Public Law 104-4, 
establishes significance thresholds for the direct costs of regulations 
on state, local, or tribal governments or the private sector that 
trigger certain agency reporting requirements. The statutory thresholds 
established in UMRA were $50 million for intergovernmental mandates and 
$100 million for private-sector mandates in 1996. According to the 
Congressional Budget Office, the thresholds for 2019, which are 
adjusted annually for inflation, are $82 million and $164 million, 
respectively, for intergovernmental and private-sector mandates.\32\ 
This final rule results in cost savings of approximately $55,000 to 
$2,100,000 per year at a 7 percent discount rate and is the least 
burdensome alternative that achieves the objective of the rule. It is 
not significant under UMRA. Therefore, PHMSA is not required to prepare 
a written statement.

J. Environmental Assessment

    The National Environmental Policy Act of 1969 (NEPA), as amended 
(42 U.S.C. 4321-4375), and implementing regulations by the Council on 
Environmental Quality (CEQ) (40 CFR part 1500), require that Federal 
agencies consider the consequences of major Federal actions and prepare 
a detailed statement on actions that significantly affect quality of 
the human environment. The CEQ regulations require Federal agencies to 
conduct an environmental review considering (1) the need for the 
action, (2) alternatives to the action, (3) probable environmental 
impacts of the action and alternatives, and (4) the agencies and 
persons consulted during the consideration process.
1. Need for the Action
    This final rule amends the HMR (49 CFR parts 171-180) to maintain 
alignment with international standards, in part, 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 final rule are not 
adopted in the HMR, U.S. companies--including numerous small entities 
competing in foreign markets--would be at an economic disadvantage 
because they would be required to comply with a dual system of 
regulations. The changes to the HMR contained in this 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. The rule harmonizes the HMR 
with international standards 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 in this rule.
2. Alternatives
    In developing this rulemaking, PHMSA is considering the following 
alternatives:
Alternative (1): No Action Alternative
    If PHMSA were to take no action, current regulations would remain 
in place and no new provisions would be added.
Alternative (2): Preferred Alternative
    This alternative is the adoption of this final rule. The amendments 
included in this alternative are more fully addressed in the preamble 
and regulatory text sections of this final rule.
3. Environmental Impacts
    Hazardous materials are substances that may pose a threat to public 
safety or the environment during transportation because of their 
physical, chemical, or nuclear properties. Under the HMR, hazardous 
materials are transported by aircraft, vessel, rail, and highway. The 
hazardous materials regulatory system is a risk management system that 
is prevention-oriented and focused on identifying a safety hazard and 
reducing the probability and quantity of a hazardous material release.

[[Page 27850]]

The potential for environmental damage or contamination exists when 
packages of hazardous materials are involved in accidents or en route 
incidents resulting from cargo shifts, valve failures, package 
failures, loading, unloading, collisions, handling problems, or 
deliberate sabotage. The release of hazardous materials can cause the 
loss of ecological resources (e.g., wildlife habitats) and the 
contamination of air, aquatic environments, and soil. Contamination of 
soil can lead to the contamination of ground water. Compliance with the 
HMR substantially reduces the possibility of accidental release of 
hazardous materials.
Alternative (1): No Action Alternative
    If PHMSA takes no action, the current regulations would remain in 
place and no new provisions would be added. With this alternative, 
efficiencies gained through harmonization with updates to international 
transport standards--including regulated substances, definitions, 
packagings, stowage requirements/codes, flexibilities allowed, enhanced 
markings, segregation requirements, etc.--would not be realized. Taking 
no action would mean enhanced and clarified regulatory requirements 
intended to decrease the risk of environmental and safety incidents 
would not be adopted. PHMSA believes these amendments will increase 
standardization and consistency of regulations, which will result in 
greater protection of human health and the environment. Consistency 
between United States and international regulations enhances the safety 
and environmental protection of international hazardous materials 
transportation through a 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 rule will 
reduce 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.
    Not adopting the proposed environmental and safety requirements in 
the final rule under the No Action Alternative would result in a lost 
opportunity for reducing environmental and safety-related incidents.
Alternative (2): Preferred Alternative
    PHMSA selected the preferred alternative. Potential environmental 
impacts of each proposed amendment in the preferred alternative are 
discussed as follows:
    1. Incorporation by Reference: PHMSA is updating references to 
various international hazardous materials transport standards 
including, in part, 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, PHMSA is adding three 
new references to standards and updating six other references to 
standards applicable to the manufacture use and requalification of 
pressure vessels published by the ISO.
    PHMSA believes these amendments will increase standardization and 
consistency of regulations, which will result in greater protection of 
human health and the environment. Consistency between United States and 
international regulations enhances the safety and environmental 
protection of international hazardous materials transportation through 
a 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 rule will 
reduce 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.
    2. Consistent with amendments adopted into the UN Model 
Regulations, PHMSA is revising the Hazardous Materials Table in Sec.  
172.101 to include 12 new n.o.s. entries for articles containing 
dangerous goods and adding defining criteria, authorized packagings, 
and safety requirements for transportation of these articles. Inclusion 
of the new entries in the HMT allows for identification of appropriate 
packaging for 12 n.o.s. entries, which is intended to reduce the 
likelihood of release of hazardous materials that threaten human health 
and safety and the environment.
    3. PHMSA is making 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 inclusions in the HMT provide a greater level of 
protection against release and consistency across borders. These 
provisions are not expected to have a material impact on the 
environment.
    4. Changes to the corrosivity classification procedures to include 
methods that do not involve testing for making a corrosivity 
classification determination for mixtures.
    This amendment permits additional flexibility for classifying 
corrosive

[[Page 27851]]

mixtures and provides 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. The 
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 is requiring the creation of a lithium cell or 
battery test summary.
    PHMSA believes that these amendments provide important additional 
information to downstream shippers and consumers of lithium batteries, 
including a standardized set of elements that provide traceability and 
accountability that lithium cells and batteries offered for transport 
contain specific information on the required UN 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 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 hazardous material. The 
segregation requirements are intended to avoid the cumulative effects 
of a fire involving both goods simultaneously. PHMSA believes that this 
amendment will provide for a net increase in environmental protection 
and safety by potentially lessening the severity of a fire aboard an 
aircraft, thus preventing 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 changes closely 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 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 changes in this final rule 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 final rule increase protections aimed at avoiding 
safety and environmental risks.
4. Agencies Consulted
    PHMSA has coordinated with the FAA, the FMCSA, the FRA, and the 
U.S. Coast Guard in the development of this final rule. PHMSA 
considered the views expressed in comments to the NPRM submitted by 
members of the public, state and local governments, and industry.
5. Conclusion
    PHMSA has determined that no significant environmental impacts will 
result from this the adoption of this final rule. The provisions of the 
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 received no 
comments specially addressing the environmental impacts of the changes 
made in this final rule.

K. Privacy Act

    In accordance with 5 U.S.C. 553(c), DOT solicits comments from the 
public to better inform its rulemaking process. DOT posts these 
comments, without edit, including any personal information the 
commenter provides, to www.regulations.gov, as described in the system 
of records notice (DOT/ALL-14 FDMS), DOT's complete Privacy Act 
Statement in the Federal Register published on April 11, 2000 (65 FR 
19477), and at http://www.dot.gov/privacy.

L. International Trade Analysis and Executive Order 13609

    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. Pursuant to these Acts, the establishment of 
standards is not considered an unnecessary obstacle to the foreign 
commerce of the United States, so long as the standards have a 
legitimate domestic objective, such as the protection of safety, and do 
not operate in a manner that excludes 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 
notes the purpose is to ensure the safety of the American public and 
has assessed the effects of this final rule to ensure that it does not 
exclude imports that meet this objective. The final rule will have 
positive impacts on international trade because it increases the level 
of harmonization between U.S. regulations and international standards, 
which is also consistent with the policy in Executive Order 13609, 
``Promoting International Regulatory Cooperation,'' 77 FR 26413. As a 
result, this final rule is not considered as creating an unnecessary 
obstacle to foreign commerce.

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 consensus standard bodies. This final 
rule involves multiple voluntary consensus standards that are 
identified and discussed in the section-by-section analysis for Sec.  
171.7.

    238 Neutron radiation detectors: Neutron radiation detectors 
containing non-pressurized boron trifluoride gas in excess of 1 gram 
(0.035 ounces) and radiation detection systems containing such neutron 
radiation detectors as components may be transported by highway, rail, 
vessel, or cargo aircraft in accordance with the following:
    a. Each radiation detector must meet the following conditions:
    (1) The pressure in each neutron radiation detector must not exceed 
105 kPa absolute at 20 [deg]C (68 [deg]F);
    (2) The amount of gas must not exceed 13 grams (0.45 ounces) per 
detector; and
    (3) Each neutron radiation detector must be of welded metal 
construction with brazed metal to ceramic feed through assemblies. 
These detectors must have a minimum burst pressure of 1800 kPa as 
demonstrated by design type qualification testing; and
    (4) Each detector must be tested to a 1 x 10-10 cm\3\/s 
leaktightness standard before filling.
    b. Radiation detectors transported as individual components must be 
transported as follows:
    (1) They must be packed in a sealed intermediate plastic liner with 
sufficient absorbent or adsorbent material to absorb or adsorb the 
entire gas contents.
    (2) They must be packed in strong outer packagings and the 
completed package must be capable of withstanding a 1.8 meter (5.9 
feet) drop without leakage of gas contents from detectors.
    (3) The total amount of gas from all detectors per outer packaging 
must not exceed 52 grams (1.83 ounces).
    c. Completed neutron radiation detection systems containing 
detectors meeting the conditions of paragraph a of this special 
provision must be transported as follows:
    (1) The detectors must be contained in a strong sealed outer 
casing;
    (2) The casing must contain include sufficient absorbent or 
adsorbent material to absorb or adsorb the entire gas contents;
    (3) The completed system must be packed in strong outer packagings 
capable of withstanding a 1.8 meter (5.9 feet) drop test without 
leakage unless a system's outer casing affords equivalent protection.
    d. Except for transportation by aircraft, neutron radiation 
detectors and radiation detection systems containing such detectors 
transported in accordance with paragraph a of this special provision 
are not subject to the labeling and placarding requirements of part 172

    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, 2023, unless we terminate them 
earlier or extend them beyond that date by notice of a final rule in 
the Federal Register.

classifying the mixture to be corrosive to skin.
    (ii) To determine whether a mixture containing corrosive substances 
must be considered a corrosive mixture and to assign a packing group, 
the calculation method in the flow chart in Appendix I must be applied. 
For this calculation method, generic concentration limits apply 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.
    (iii) 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).
    (iv) 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:

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:
    (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

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 percent, by mass, if assigned to Packing Group I 
or II; or
    (B) Less than 30 percent, 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 fiberboard 
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.

32. 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 
level. The following packagings are authorized:
    (i) Drums (1A2, 1B2, 1N2, 1H2, 1D, 1G);
    (ii) Boxes (4A, 4B, 4N, 4C1, 4C2, 4D, 4F, 4G, 4H1, 4H2); and
    (iii) Jerricans (3A2, 3B2, 3H2).
    (2) In addition, for robust articles, the following non-
specification packagings are authorized:
    (i) Strong outer packagings constructed of suitable material and of 
adequate strength and design in relation to the packaging capacity and 
its intended use. Each package must conform to the packaging 
requirements of subpart B of this part, except for the requirements in 
Sec. Sec.  173.24(a)(1) and 173.27(e).
    (ii) Articles may be transported unpackaged or on pallets when the 
hazardous materials are afforded equivalent protection by the article 
in which they are contained.
    (g) The nature of the containment must be as follows--
    (1) In the event of damage to the receptacles containing the 
hazardous materials, no leakage of the hazardous materials from the 
machinery or apparatus is possible. A leakproof liner may be used to 
satisfy this requirement.
    (2) Receptacles containing hazardous materials must be secured and 
cushioned so as to prevent their breakage or leakage and to control 
their movement within the machinery or apparatus during normal 
conditions of transportation. Cushioning material must not react 
dangerously with the content of the receptacles. Any leakage of the 
contents must not substantially impair the protective properties of the 
cushioning material.
    (3) Receptacles for gases, their contents, and filling densities 
must conform to the applicable requirements of this subchapter, unless 
otherwise approved by the Associate Administrator.

34. In Sec.  173.304b, paragraph (b)(5) is revised to read as follows:


Sec.  173.304b  Additional requirements for shipment of liquefied 
compressed gases in UN pressure receptacles.

* * * * *
    (b) * * *
    (5) For liquefied gases charged with compressed gases, both 
components--the liquefied gas and the compressed gas--must be taken 
into consideration in the calculation of the internal pressure in the 
pressure receptacle. The maximum mass of contents per liter of water 
capacity shall not exceed 95 percent of the density of the liquid phase 
at 50 [deg]C (122 [deg]F); in addition, the liquid phase shall not 
completely fill the pressure receptacle at any temperature up to 60 
[deg]C (140 [deg]F). When filled, the internal pressure at 65 [deg]C 
(149 [deg]F) shall not exceed the test pressure of the pressure 
receptacles. The vapor pressures and volumetric expansions of all 
substances in the pressure receptacles shall be considered. The maximum 
filling limits may be determined using the procedure in (3)(e) of P200 
of the UN Recommendations.

    (a) * * *
    (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 or requalified and marked by a 
facility registered by Transport Canada in accordance with the 
Transport Canada TDG Regulations (IBR, see Sec.  171.7 of this 
subchapter). 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 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.

including MEGC's pressure receptacles, must be requalified in 
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).
