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

provisions, packaging authorizations, bulk packaging requirements, and passenger and cargo aircraft maximum quantity limits. 
•Articles containing dangerous 
goods: PHMSA proposes to add a 
classification system for articles containing hazardous materials that do not already have a proper shipping name. This proposal would address situations in which hazardous materials or hazardous materials residues are present in articles, and authorize a safe method to transport articles that may be too large to fit into typical packages. Absent these provisions to package and transport these materials safely, these articles may be offered for transport under provisions that do not adequately account for the physical and chemical properties of the substances and may require the issuance of an approval by PHMSA’s Associate Administrator for Hazardous Materials Safety. 
•Lithium Battery Test Summary: 
PHMSA proposes the inclusion of a lithium battery test summary requirement. The HMR require lithium battery manufacturers to subject their batteries to appropriate UN design tests to ensure they are classified correctly for transport, and develop records of successful test completion. The proposed test summary would include a standardized set of elements that provide traceability and accountability, thereby ensuring that lithium cell and battery designs offered for transport meet the appropriate UN tests. 
•Baggage Equipped with Lithium 
Batteries: PHMSA proposes to amend 
the aircraft passenger provisions for carriage of baggage equipped with lithium batteries intended to power features such as location tracking, battery charging, digital weighing, or motors (sometimes referred to as ‘‘smart luggage’’). Specifically, baggage equipped with a lithium battery or batteries would be required to be carried in the cabin of the aircraft unless the 
battery or batteries are removed. 
•Segregation of Lithium Batteries 
from Specific Hazardous Materials: PHMSA proposes requirements to segregate lithium cells and batteries from certain other hazardous materials, notably flammable liquids, when offered for transport or transported on aircraft. PHMSA is taking this action to promote consistency with the ICAO Technical Instructions and a recommendation (A– 16–001) from the National Transportation Safety Board (NTSB) stemming from the investigation of the July 28, 2011, in-flight fire and crash of Asiana Airlines Flight 991 incident that resulted in the loss of the aircraft and crew. The investigation report cited as 
a contributing factor the flammable materials and lithium ion batteries that were loaded together either in the same or adjacent pallets. 
•Alternative criteria for classification 
of corrosive materials: PHMSA proposes to include non-testing alternatives for classifying corrosive mixtures that uses existing data on their chemical properties. Currently the HMR require offerors to classify Class 8 corrosive material and assign a packing group based on test data. The HMR authorize a skin corrosion test and various in vitro test methods that do not involve animal testing. However, data obtained from testing is currently the only data acceptable for classification and assigning a packing group. These alternatives would afford offerors the ability to make a classification and packing group assignment without the need to conduct physical tests. 
•Provisions for Polymerizing 
Substances: PHMSA is proposing to 
extend the sunset dates for provisions concerning the transportation of polymerizing substances from January 2, 2019 to January 2, 2021. This additional time will allow PHMSA to finalize research and analyze comments and data concerning the issue submitted to the docket for this NPRM. This information will allow us to have a more comprehensive understanding of polymerizing substances and further consider the most appropriate transport provisions for these materials. 
If adopted in a final rule, the 
amendments proposed in this NPRM will result in minimal burdens on the regulated community. The benefits achieved from their adoption include enhanced transportation safety resulting from the consistency of domestic and international hazard communication and continued access to foreign markets by U.S. manufacturers of hazardous materials. PHMSA anticipates that most of the amendments in this NPRM will result in cost savings and will ease the 
regulatory compliance burden for shippers engaged in domestic and international commerce, including trans-border shipments within North America. 
PHMSA solicits comment from the 
regulated community on these amendments and others proposed in this NPRM pertaining to: Need, benefits, and costs of international harmonization; impact on safety; and any other relevant concerns. In addition, PHMSA solicits comment regarding approaches to reducing the costs of this rule while maintaining or increasing the benefits. In its preliminary analysis, PHMSA concluded that the aggregate benefits of the amendments proposed in 
this NPRM justify their aggregate costs. Nonetheless, PHMSA solicits comment on specific changes (i.e., greater 
flexibility with regard to a particular amendment) that might improve the rule. 
II. Background 
Federal law and policy strongly favor 
the harmonization of domestic and 
international standards for hazardous materials transportation. The Federal hazardous materials law (49 U.S.C. 5101 et seq.) directs PHMSA to participate in 
relevant international standard-setting bodies and requires alignment of the HMR with international transport standards to the extent practicable. Although Federal hazmat law permits PHMSA to depart from international standards to promote safety or other overriding public interest, it otherwise encourages domestic and international harmonization (see 49 U.S.C. 5120). 
In a final rule published December 21, 
1990 (Docket HM–181; 55 FR 52402), PHMSA’s predecessor—the Research and Special Programs Administration (RSPA)—comprehensively revised the HMR for international harmonization with the UN Model Regulations. The UN Model Regulations constitute a set of recommendations issued by the United Nations Sub-Committee of Experts (UNSCOE) on the Transport of Dangerous Goods and the United Nations Sub-Committee of Experts on the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). The UN Model Regulations are amended and updated biennially by the UNSCOE and serve as the basis for national, regional, and international modal regulations, including the IMDG Code and the ICAO Technical Instructions. 
Since publication of the 1990 rule, 
PHMSA has issued 12 subsequent international harmonization rulemakings.
1These rulemakings were 
based on biennial updates of the UN Model Regulations, the IMDG Code, and the ICAO Technical Instructions. 
Harmonization becomes increasingly 
important as the volume of hazardous materials transported in international commerce grows. Harmonization not only facilitates international trade by minimizing the costs and other burdens of complying with multiple or inconsistent safety requirements for

2Amendment 39–18 to the IMDG Code may be 
voluntarily applied on January 1, 2019; however, 
the previous amendment remains effective through December 31, 2019. 3Broad Agency Announcement (BAA) for 
innovative research and development projects, 
January 19, 2017. https://www.fbo.gov/spg/DOT/ PHMSA/PHMSAHQ/DTPH5617PHMSABAA/ listing.html. transportation of hazardous materials, 
but it also enhances safety when the international standards provide an appropriate level of protection. PHMSA actively participates in the development of international standards for the transportation of hazardous materials and promotes the adoption of standards consistent with the HMR. When considering alignment of the HMR with international standards, PHMSA reviews and evaluates each amendment on its own merit, its overall impact on transportation safety, and the economic implications associated with its adoption. Our goal is to harmonize with international standards without 
diminishing the level of safety currently provided by the HMR or imposing undue burdens on the regulated community. 
Based on recent review and 
evaluation, PHMSA proposes to revise the HMR to incorporate changes from the 20th Revised Edition of the UN Model Regulations, Amendment 39–18 to the IMDG Code,
2and the 2019–2020 
Edition of the ICAO Technical Instructions, all of which become effective January 1, 2019. 
In addition, PHMSA proposes to 
incorporate by reference the newest editions of various international standards. The standards incorporated by reference are authorized for use, under specific circumstances, in part 171 subpart C of the HMR. This proposed rule is necessary to incorporate revisions to the international standards and, if adopted in the HMR, will be effective January 1, 2019. 
PHMSA published a final rule under 
Docket HM–215N [82 FR 15796 (March 30, 2017)] that, among other things, added four new Division 4.1 entries for polymerizing substances to the HMT, and added into the HMR defining criteria, authorized packagings, and safety requirements including, but not limited to, stabilization methods and operational controls. In this prior rulemaking, PHMSA indicated that these changes would be in effect until January 2, 2019. During the interim time period between publication of the final rule and January 2, 2019, PHMSA indicated it would review and research the implications of the polymerizing substance amendments, and readdress the issue in the next international harmonization rulemaking. On January 19, 2017, a Broad Agency 
Announcement (BAA)
3was issued 
soliciting white papers from those 
interested in undertaking research into the appropriate temperature controls for polymerizing substances across all package sizes and the impact of gas generation from a polymerizing reaction. Submissions were received and reviewed by a team of experts to verify, in accordance with the terms of the BAA, the technical appropriateness of the proposed work, and the past performance of the submitter. Recommendations were submitted to the PHMSA Research and Development staff on February 14th, 2018. The Research and Development staff is undertaking the necessary next steps to initiate the research. By way of this rulemaking, PHMSA also solicits comments and data from shippers and classifiers of polymerizing substances concerning their experiences operating under the transport provisions applied to polymerizing substances in the HM– 215N final rule. Specifically, PHMSA seeks information regarding: 
•Whether affected entities have 
experienced difficulties resulting from differing domestic and international requirements for polymerizing substances (e.g., differing temperature 
thresholds before temperature control is required in portable tanks and requirements for successfully passing Test Series E prior to offering for transport in a portable tank or IBC); 
•The experiences of the regulated 
community in utilizing Test Series E with polymerizing substances; and 
•Whether there are alternative tests 
that can indicate appropriate responses when potentially polymerizing substances are heated under confinement. 
As this research project is presently in 
the pre-award phase prescribed in the BAA and will not be completed prior to the expected publication date of a final rule for this NPRM, PHMSA is proposing to extend the sunset dates for provisions concerning the transportation of polymerizing substances from January 2, 2019 to January 2, 2021. This additional time should allow PHMSA to complete its ongoing research project and analyze all comments and data concerning the issue submitted to the docket for this NPRM. This information will increase our comprehension of polymerizing substances and further consider the most appropriate transport provisions for these materials. This new sunset 
date is proposed in amendments to §§ 172.101, 172.102, 173.21, and 173.124. 
III. Incorporation by Reference 
Discussion Under 1 CFR Part 51 
The UN Model Regulations, Manual 
of Tests and Criteria, and Globally Harmonized System of Classification and Labelling of Chemicals, as well as all of the Transport Canada Clear Language Amendments, are free and easily accessible to the public on the internet, with access provided through the parent organization websites. The ICAO Technical Instructions, IMDG Code, and all ISO references are available for interested parties to purchase in either print or electronic versions through the parent organization websites. The price charged for those not freely available helps to cover the cost of developing, maintaining, hosting, and accessing these standards. The specific standards are discussed in greater detail in the following analysis. 
IV. Harmonization Proposals in This 
NPRM 
In addition to various other revisions 
to the HMR, PHMSA proposes the following amendments to harmonize the HMR with the most recent revisions to the UN Model Regulations, ICAO Technical Instructions, and IMDG Code, as well as several amendments to further align with the Transport Canada TDG Regulations: 
•Incorporation by Reference: 
PHMSA proposes to incorporate by reference the newest versions of various international hazardous materials standards, including the 2019–2020 Edition of the ICAO Technical Instructions; Amendment 39–18 to the IMDG Code; the 20th Revised Edition of the UN Model Regulations; amendment 1 to the 6th Revised Edition of the UN Manual of Tests and Criteria; and the 7th Revised Edition of the GHS. Additionally, we propose to update our incorporation by reference of the Transport Canada TDG Regulations to include SOR/2016–95 published June 1, 2016; SOR/2017–137 published July 12, 2017; and SOR/2017–253 published December 13, 2017. Finally, in this NPRM, PHMSA proposes the adoption of updated ISO standards. 
•Hazardous Materials Table: 
PHMSA proposes amendments to the HMT to add, revise, or remove certain proper shipping names, hazard classes, packing groups, special provisions, packaging authorizations, bulk packaging requirements, vessel stowage and segregation requirements, and

passenger and cargo aircraft maximum 
quantity limits. 
•Articles containing dangerous 
goods: PHMSA proposes to add a 
classification scheme for articles containing hazardous materials that do not already have a proper shipping name. This proposal would address situations in which hazardous materials or hazardous materials residues are present in articles. This proposal would authorize a safe method to transport articles that may be too large to fit into typical packages. Absent these provisions to package and transport these materials safely, these articles may be offered for transport under provisions that do not adequately account for the physical and chemical properties of the substances and may require the issuance of an approval by PHMSA’s Associate Administrator for Hazardous Materials Safety. 
•Lithium Battery Test Summary: 
PHMSA proposes the inclusion of a lithium battery test summary requirement. The HMR require lithium battery manufacturers to subject their batteries to appropriate UN design tests to ensure they are classified correctly for transport, and develop records of successful test completion. The proposed test summary would include a standardized set of elements that provide traceability and accountability, thereby ensuring that lithium cell and battery designs offered for transport meet the appropriate UN tests. 
•Baggage Equipped with Lithium 
Batteries: PHMSA proposes to amend 
the aircraft passenger provisions for carriage of baggage equipped with lithium batteries intended to power features such as location tracking, battery charging, digital weighing, or motors (sometimes referred to as ‘‘smart luggage’’). Specifically, baggage equipped with a lithium battery or batteries would be required to be carried in the cabin of the aircraft unless the battery or batteries are removed.

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

Competency Based Training approach. 
To aid the public in developing comments, three documents from ICAO DGP and UNSCOE containing information pertaining to Competency Based Training have been provided in the public docket for this rulemaking. 
Any comments received may be 
utilized to better inform PHMSA’s work in various international forums. Below are some thought starters for consideration for your comments: 
•If you currently follow a 
Competency Based Training approach to meet the requirements in Part 172, Subpart H: 
ÆDo you have suggestions or lessons 
learned that you would like to share? 
ÆWhat information or tools did/do 
you consider most helpful in implementing a Competency Based Training approach? 
ÆHave you reviewed the ICAO 
guidance provided in the Docket? If so, did you find the guidance helpful? 
•If you do not follow a Competency 
Based Training approach to meet the requirements in Part 172, Subpart H: 
ÆHave you reviewed the ICAO 
guidance provided in the Docket? If so, did you find the guidance helpful? 
ÆAre you aware of any barriers to 
implementing a Competency Based Training approach? 
VI. Section-by-Section Review 
The following is a section-by-section 
review of the amendments proposed in 
this NPRM: 
Part 171 Section 171.7 
Section 171.7 provides a listing of all 
voluntary consensus standards 
incorporated by reference into the HMR, as directed by the ‘‘National Technology Transfer and Advancement Act of 1996.’’ According to the Office of Management and Budget (OMB), Circular A–119, ‘‘Federal Participation in the Development and Use of Voluntary Consensus Standards and in Conformity Assessment Activities,’’ government agencies must use voluntary consensus standards wherever practical in the development of regulations. Agency adoption of industry standards promotes productivity and efficiency in government and industry, expands opportunities for international trade, conserves resources, improves health and safety, and protects the environment. 
PHMSA actively participates in the 
development and updating of consensus standards through representation on more than 20 consensus standard bodies and regularly reviews updated consensus standards to consider their merit for inclusion in the HMR. For this rulemaking, PHMSA evaluated updated international consensus standards pertaining to proper shipping names, hazard classes, packing groups, special provisions, packaging authorizations, air transport quantity limitations, and vessel stowage requirements. It determined that the revised standards provide an enhanced level of safety without imposing significant compliance burdens. These standards have well-established and documented safety histories, and their adoption will maintain the high safety standard currently achieved under the HMR. Therefore, in this NPRM, PHMSA proposes to add and revise the following incorporation by reference materials: 
•Paragraph (s)(2) would be added, to 
incorporate the International Atomic Energy Agency Code of Conduct on the Safety and Security of Radioactive Sources. Section 172.800 references the incorporation by reference of this document; however, this entry does not currently appear in § 171.7. The proposed addition of this paragraph would correct this oversight. The incorporation of this document in § 172.800 provides a list of Category 1 and 2 radioactive sources for which offerors or carriers require a security plan. 
•Paragraph (t)(1), which incorporates 
the International Civil Aviation 
Organization Technical Instructions for 
the Safe Transport of Dangerous Goods by Air (ICAO Technical Instructions), 2015–2016 Edition, would be revised to incorporate the 2019–2020 Edition. These instructions contain the detailed instructions for the international transport of hazardous materials by air. 
•Paragraph (v)(2), which 
incorporates the International Maritime Organization International Maritime 
Dangerous Goods Code (IMDG Code), Incorporating Amendment 38–16 (English Edition), would be revised to incorporate the 39–18 (English Edition), 2018 Edition. This code contains the detailed instructions for the international transport of hazardous materials by vessel. 
•Paragraph (w), which incorporates 
various International Organization for 
Standardization entries, would be 
revised to incorporate by reference standards for the specification, design, construction, testing, and use of gas cylinders: 
—ISO 11118(E), Gas cylinders—Non-

•Paragraphs (aa)(1)–(4), which 
updates 4 existing Organization for 
Economic Cooperation and Development (OECD) guidelines 
concerning corrosivity testing (Nos. 404, 430, 431, & 435). The references to these standards would be updated to the 2015 versions of the standards. 
•Paragraph (bb)(1), which 
incorporates the Transport Canada Transportation of Dangerous Goods Regulations, would add subparagraphs (xx), (xxi), and (xxii), to include SOR/ 2016–95 published June 1, 2016; SOR/ 2017–137 published July 12, 2017; and SOR/2017–253 published December 13, 2017, respectively. These proposed additions are to incorporate changes to the Transport Canada Transportation of 
Dangerous Goods Regulations. 
•Paragraph (bb)(2) would be added 
to incorporate by reference Containers for Transport of Dangerous Goods by Rail, a Transport Canada standard that was published in 2013. The standard applies to the design, manufacture, maintenance and qualification of tank cars and ton containers and the selection and use of large containers or transport units used in the handling, offering for transport, or transporting of dangerous goods by rail. •Paragraph (dd)(1), which 
incorporates the United Nations 
Recommendations on the Transport of Dangerous Goods—Model Regulations, 19th Revised Edition (2015), Volumes I and II, would be revised to incorporate the 20th Revised Edition (2017), Volumes I and II. This standard presents a basic scheme of provisions that allow uniform development of national and international regulations governing the various modes of transport. 
•Paragraph (dd)(2)(ii) would be 
added to incorporate the United Nations Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, 6th Revised Edition, Amendment 1. This standard contains criteria, test methods, and procedures to be used for the classification of hazardous materials according to the UN Model Regulations. 
•Paragraph (dd)(3), which 
incorporates the United Nations Recommendations on the Transport of Dangerous Goods, Globally Harmonized System of Classification and Labelling

on the Transport of Dangerous Goods, Globally Harmonized System of Classification and Labelling of Chemicals (GHS), 7th Revised Edition (2017). This standard helps identify the intrinsic hazards found in substances and mixtures and to convey hazard information about these hazards. 
Section 171.8 
Section 171.8 defines terms generally 
used throughout the HMR that have 
broad or multi-modal applicability. In this NPRM, PHMSA is proposing to amend the definition of ‘‘UN pressure receptacle’’ to include pressure drums. Additionally, PHMSA proposes to add a definition for ‘‘UN Pressure drum’’ to mean a welded transportable pressure receptacle of a water capacity exceeding 150 L and not more than 1,000 L (e.g., cylindrical receptacles equipped with rolling hoops, spheres on skids). These amendments provide defining terms related to pressure drums for which ISO 21172–1:2015(E) Gas cylinders— Welded steel pressure drums up to 3,000 litres capacity for the transport of gases—Design and construction—Part 1: Capacities up to 1,000 litres is proposed for incorporation in § 178.71. 
Section 171.12 
Section 171.12 prescribes 
requirements for the use of the 
Transport Canada TDG Regulations. In a March 30, 2017, final rule [HM–215N; 82 FR 15795], PHMSA amended the HMR to expand recognition of cylinders and pressure receptacles, cargo tank repair facilities, and certificates of equivalency in accordance with the TDG Regulations. The goal of these amendments is to promote flexibility and permit the use of advanced technology for the requalification and use of pressure receptacles; doing so will provide for a broader selection of authorized pressure receptacles, reduce the need for special permits, and to facilitate cross-border transportation of these cylinders. In this NPRM, PHMSA proposes to clarify the recognition of certificates of equivalency issued by Transport Canada. Transport Canada issues equivalency certificates as both a competent authority approval and for an alternative means of compliance with TDG Regulations. PHMSA provides reciprocity for equivalency certificates that are issued by Transport Canada as an alternative to the TDG Regulations; PHMSA does not provide recognition to Canada’s competent authority approvals. In this NPRM, PHMSA is proposing to amend paragraph (a)(1) to clarify the extent of reciprocity regarding certificates of equivalency. 
Additionally, PHMSA is proposing to 
amend paragraph (a)(3)(v) to update the standard incorporated by reference to which Canadian rail cars must conform. The existing reference to the Canadian General Standards Board standard 43.147 is replaced with Containers for Transport of Dangerous Goods by Rail (2013). 
Part 172 Section 172.101 
Section 172.101 contains the HMT 
and provides instructions for its use. In 
this NPRM, PHMSA is proposing to revise the instructional text that precedes the HMT for paragraph (e) of this section. 
Paragraph (e) of § 172.101 provides 
instructions for the use of column (4) of the HMT. Column (4) lists the identification number assigned to each proper shipping name. Most identification numbers are preceded by the letters ‘‘UN’’ and are associated with proper shipping names, which may be used for both domestic and international transportation. Some proper shipping names are assigned ‘‘NA’’ or ‘‘North American’’ numbers. As it currently stands, the HMR states that NA numbers are afforded recognition in both the United States and Canada. Furthermore, under § 171.12, the HMR treats transporting hazardous materials to Canada in the same way as domestic transportation. This is problematic, however, because specific dangerous goods are classified

differently in the two countries. The 
Transport Canada Transportation of Dangerous Goods Regulations limit the use of NA numbers on transport documents to materials classified as ‘‘Consumer commodity,’’ and do not allow for documentation of other NA numbers. Therefore, in this NPRM, PHMSA is proposing to revise paragraph (e) to indicate that NA numbers are only recognized for use in the United States. 
Hazardous Materials Table (HMT) 
In this NPRM, PHMSA is proposing to 
amend the HMT. Readers should review 
all changes for a complete understanding of the amendments. For purposes of the Government Printing Office’s typesetting procedures, proposed changes to the HMT appear under three sections of the Table, ‘‘remove,’’ ‘‘add,’’ and ‘‘revise.’’ Certain entries in the HMT, such as those with revisions to the proper shipping names, appear as a ‘‘remove’’ and ‘‘add.’’ Proposed amendments to the HMT include the following: 
New HMT Entries 
•UN3537 Articles containing 
flammable gas, n.o.s. 
•UN3538 Articles containing non- 
flammable, non-toxic gas, n.o.s. 
•UN3539 Articles containing toxic gas, 
n.o.s. 
•UN3540 Articles containing 
flammable liquid, n.o.s. 
•UN3541 Articles containing 
flammable solid, n.o.s. 
•UN3542 Articles containing a 
substance liable to spontaneous 
combustion, n.o.s. 
•UN3543 Articles containing a 
substance which emits flammable gas in contact with water, n.o.s. 
•UN3544 Articles containing 
oxidizing substance, n.o.s. 
•UN3545 Articles containing organic 
peroxide, n.o.s. 
•UN3546 Articles containing toxic 
substance, n.o.s. 
•UN3547 Articles containing corrosive 
substance, n.o.s. 
•UN3548 Articles containing 
miscellaneous dangerous goods, n.o.s. 
PHMSA proposes to add a 
classification scheme for articles 
containing hazardous materials not otherwise specified by name in the HMR that contain hazardous materials of various hazard classes and divisions. This proposal addresses transportation scenarios where various hazardous materials or hazardous materials residues are present in articles above the quantities currently authorized for dangerous goods in machinery or apparatus. This proposal authorizes safe and secure methods to transport articles 
that may be too large to fit into typical packagings. Absent provisions to package and transport these materials safely, such articles may be offered for transport under provisions that do not adequately account for the physical and chemical properties of the substances or mode of transport and may require the issuance of an approval by the Associate Administrator for Hazardous Materials Safety. 
•UN3535 Toxic solid, flammable, 
inorganic, n.o.s. Consistent with the 20th Revised 
Edition of the UN Model Regulations, 
this new generic entry addresses toxic solids with a flammable subsidiary risk in Packing Groups I and II. 
•UN3536 Lithium batteries installed 
in cargo transport unit lithium ion 
batteries or lithium metal batteries 
This new HMT entry addresses 
lithium metal and lithium ion batteries 
installed in a cargo transport unit and designed only to provide power external to the cargo transport unit. The lithium batteries must meet the requirements of § 173.185 and contain the necessary systems to prevent overcharge and over discharge between the batteries. Such units are forbidden for transport on aircraft. 
Amendments to Column (2) Hazardous 
Materials Descriptions and Proper Shipping Names 
Section 172.101(c) describes column 
(2) of the HMT and the requirements for hazardous materials descriptions and proper shipping names. For the entry ‘‘2-Dimethylaminoethyl acrylate,’’ the word ‘‘stabilized’’ is added to the end, as the substance has been determined to polymerize in certain conditions. 
Amendments to Column (5) Packing 
Group 
The HMT entries for articles 
‘‘UN3316, Chemical kit’’ and ‘‘UN3316, First aid kit’’ are revised to remove packing group II and III assignments. This revision would revert the entries to a single row with the packing group column left blank as they existed prior to adding the packing group II and III assignments in a final rule published on 
January 8, 2015 [Docket No. PHMSA– 2013–0260 (HM–215M); 80 FR 1075]. This revision would address situations where materials in the kits are not assigned to a packing group or have packing group I assigned, as permitted by § 173.161. Amendments to Column (7) Special 
Provisions 
Section 172.101(h) describes column 
(7) of the HMT, which contains special provisions for each entry in the table. Section 172.102(c) prescribes the special provisions assigned to specific entries in the HMT. The particular modifications to the entries in the HMT are discussed below. See ‘‘Section 172.102 special provisions’’ below for a detailed discussion of the proposed additions, revisions, and deletions to the special provisions addressed in this NPRM.

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 § 176.84. 
Recent revisions to the stowage 
categories for Class 1 goods greatly simplified the stowage categories, but increased the difficulty in shipping explosives as break bulk cargo. Some shippers have found it difficult to meet the new stowage categories, particularly stowage category 04, which requires shipment on deck in a closed cargo transport unit or under deck in a closed cargo transport unit. Many of the items contained in these shipments are large and robust articles and are difficult to pack in a closed cargo transport unit. This has resulted in unnecessary delays and added expense. 
The following table addresses this 
issue through modification of the stowage categories for individual UN numbers for which under deck stowage

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

Appendix B to § 172.101 
Appendix B to § 172.101 lists marine 
pollutants regulated under the HMR. 
Based on test data submitted to PHMSA, the USCG, and the IMO, Amendment 39–18 of the IMDG Code was updated to indicate that 1-dodecene is not a marine pollutant. In this NPRM, PHMSA is proposing to amend the entry for ‘‘Dodecene’’ in the list of marine pollutants in appendix B to § 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 
VerDate Sep<11>2014 18:40 Nov 26, 2018 Jkt 247001 PO 00000 Frm 00015 Fmt 4701 Sfmt 4702 E:\FR\FM\27NOP2.SGM 27NOP2amozie on DSK3GDR082PROD with PROPOSALS260984 Federal Register / Vol. 83, No. 228 / Tuesday, November 27, 2018 / Proposed Rules 
packaging requirements, prohibitions, 
and exceptions applicable to particular quantities or forms of hazardous materials. In this NPRM, PHMSA proposes the following revisions to § 172.102 special provisions: 
•Special provision 132. This special 
provision prescribes conditions for use of description ‘‘UN 2071, Ammonium nitrate based fertilizer, Class 9.’’ As the composition limits and requirement on self-sustaining decomposition were replaced by a flow chart in sub-section 39.5 of the new Manual of Tests and Criteria, part III, section 39, the corresponding UN Model Regulations special provision 193 was revised by removing the specific conditions and making a reference to the applicable section of the UN Manual of Tests and Criteria. Consistent with these changes to the UN Model Regulations, in this NPRM, PHMSA is proposing to revise special provision 132 by removing the specific conditions applicable to use of this description and clarifying that UN 2071 may only be used for ammonium nitrate-based compound fertilizers and that they must be classified in accordance with the procedure as set out in the Manual of Tests and Criteria, part III, section 39. 
•Special provision 150. This special 
provision prescribes conditions for use of description ‘‘UN 2067, Ammonium nitrate based fertilizer, Division 5.1.’’ As the composition limits were replaced by a flow chart in sub-section 39.5 of the new Manual of Tests and Criteria, part III, section 39, the corresponding UN Model Regulations special provision 307 was revised by removing the specific conditions and making a reference to the applicable section of the UN Manual of Tests and Criteria. Consistent with these changes to the UN Model Regulations, in this NPRM, PHMSA is proposing to revise special provision 150 by removing the specific conditions applicable to use of this description by clarifying that UN 2067 may only be used for ammonium nitrate-based fertilizers and that they must be classified in accordance with the procedure as set out in the Manual of Tests and Criteria, part III, section 39. 
•Special provision 238. Special 
provision 238 prescribes requirements for neutron radiation detectors containing boron trifluoride. In a final 
rule published under Docket Number PHMSA 2015–0273 (HM–215N) [82 FR 15795], special provision 238 was revised to align with special provision 373 of the UN Model Regulations. In reformatting the special provision for alignment, several of the preexisting references to paragraphs within the special provision were not revised accordingly. Specifically, in this NPRM, PHMSA is proposing to remove the first instance of the text ‘‘a.’’ in the introductory text as it is not necessary and inadvertently results in two paragraphs with the same letter header. In paragraph e, the references to preceding paragraphs within the special provision are revised from a(1), a(2), and a(3) to a, b, and c, respectively. 
•Special provision 325. Consistent 
with a pre-existing Special provision 325 in the UN Model Regulations, PHMSA proposes to add new special provision 325 to assist shippers of this material by clarifying that in the case of non-fissile or fissile-excepted uranium hexafluoride, the material must be classified as ‘‘UN2978 Radioactive material, uranium hexafluoride non fissile or fissile-excepted.’’. In this 
NPRM, PHMSA proposes to assign Special provision 325 to the following entries to aid shippers: 
UN2912 Radioactive material, low 
specific activity (LSA–I) non fissile 
or fissile-excepted 
UN2913 Radioactive material, surface 
contaminated objects (SCO–I or SCO–II), non-fissile or fissile 
excepted 
UN2915 Radioactive material, Type A 
package non-special form, non 
fissile or fissile-excepted 
UN2916 Radioactive material, Type 
B(U) package non fissile or fissile- excepted 
UN2917 Radioactive material, Type 
B(M) package non fissile or fissile- excepted 
UN2919 Radioactive material, 
transported under special arrangement, non fissile or fissile 
excepted 
UN3321 Radioactive material, low 
specific activity (LSA–II) non fissile or fissile-excepted 
UN3322 Radioactive material, low 
specific activity (LSA–III) non fissile or fissile excepted 
•Special provision 347. Special 
provision 347 restricts the use of certain HMT entries classed as Division 1.4S explosive materials to those articles successfully passing Test series 6(d) of Part I of the UN Manual of Tests and Criteria. A Division 1.4 explosive is defined as an explosive that presents a minor explosion hazard such that hazardous effects are confined to a package and no projection of fragments of appreciable size or range are expected; and that an external fire must not cause virtually instantaneous explosion of almost the entire contents of a package containing a Division 1.4 explosive. Explosive articles or substances are assigned to Division 1.4, Compatibility Group S (1.4S) if hazardous effects are confined within a package or the blast and projection effects do not significantly hinder emergency response efforts. 
Special provision 347 is presently 
assigned to eight (8) Division 1.4S entries in the HMT including shaped charges, detonators, power device cartridges, detonator assemblies, and plastic bonded bursting charges. Following a review of other Division 1.4S entries, the UN Working Group on Explosives supported applying Special provision 347 to entries for articles and substances whose classification as 1.4S that are generic ‘‘not otherwise specified’’ (n.o.s.) and to UN 0367 (Fuzes, detonating) that are normally package dependent, noting that generic entries normally warrant more systematic testing. Therefore, in this NPRM, consistent with the UN Model Regulations, PHMSA proposes to add special provision 347 to the following entries: UN0349 Articles, explosives, n.o.s. UN0367 Fuzes, detonating UN0384 Components, explosive train, 
n.o.s. 
UN0481 Substances, explosive, n.o.s. 
PHMSA requests comments on 
whether this proposed provision—to add special provision 347 to the four entries—is likely to have net benefits. 
•Special provision 368. Special 
provision 368 prescribes requirements for non-fissile or fissile-excepted uranium hexafluoride that must be described as UN3507 or UN2978, as appropriate. Based on an informal working paper submitted at the 50th session of the UN SCOE on the Transport of Dangerous Goods that highlighted potential errors in the 19th revised edition of the Model Regulations, it was agreed that Special provision 368 should have been assigned to ‘‘UN 2908, Radioactive material, excepted package—empty packaging’’ because empty uncleaned packagings containing residues of non- fissile or fissile-excepted uranium hexafluoride should be classified under UN3507 or UN2978 as appropriate. Therefore, in this NPRM, PHMSA proposes to assign special provision 368 to the following entry to aid shippers: UN2908 Radioactive material, excepted package—empty packaging. 
•Special provision 369. Special 
provision 369 prescribes requirements for UN3507, Uranium hexafluoride, radioactive material, excepted package, less than 0.1 kg per package, non-fissile or fissile-excepted. In this NPRM, PHMSA proposes to revise the first sentence of the special provision for

editorial clarity by replacing the words 
‘‘a radioactive material and corrosive subsidiary risk’’ with ‘‘radioactivity and corrosive subsidiary risks.’’ 
•Special provision 383. PHMSA 
proposes to remove special provision 383 which allows certain high viscosity flammable liquids, when offered for transportation by motor vehicle, to be reassigned to Packing Group III when packaged in UN metal drums with a capacity not exceeding 220 L (58 gallons). Proposed amendments to § 173.121 in this NPRM, if adopted, would provide a larger capacity package, additional packaging options, and more modes of transport (all modes except air). PHMSA believes these amendments to § 173.121 provide more regulatory relief than the existing provisions of special provision 383, and thus are proposing the deletion of special provision 383 and the removal of the special provision from the HMT for those entries to which it is assigned. 
•Special provision 388. Consistent 
with the UN Model Regulations, PHMSA proposes to add new special provision 388, which prescribes requirements for lithium batteries containing both primary lithium metal cells and rechargeable lithium ion cells that are not designed to be externally charged and for which the existing provisions for lithium batteries do not adequately address. Such batteries must meet the following conditions: (1) The rechargeable lithium ion cells can only be charged from the primary lithium metal cells; (2) Overcharge of the rechargeable lithium ion cells is precluded by design; (3) The battery has been tested as a primary lithium battery; and (4) Component cells of the battery must be of a type proved to meet the respective testing requirements of the UN Manual of Tests and Criteria, part III, subsection 38.3. Lithium batteries conforming to special provision 388 must be assigned to UN Nos. 3090 or 3091, as appropriate. When such batteries are transported in accordance with § 173.185(c), the total lithium content of all lithium metal cells contained in the battery must not exceed 1.5 g and the total capacity of all lithium ion cells contained in the battery must not exceed 10 Wh. 
•Special provision 389. In 
conjunction with the new HMT entry 
‘‘UN3536, Lithium batteries installed in cargo transport unit lithium ion batteries or lithium metal batteries,’’ PHMSA proposes to add new special provision 389, which prescribes requirements for lithium ion batteries or lithium metal batteries installed in a cargo transport unit and designed only to provide power external to the cargo transport unit. As explained in working paper 
submitted at the 48
hsession of the UN 
SCOE on the Transport of Dangerous Goods: ‘‘These units generally consist of banks of lithium ion or lithium metal batteries, electrically connected and with the necessary battery management systems, which are secured to racks, cabinets, or similar structures which, in turn, are securely attached to the interior structure of closed cargo transport units (typically either freight containers or freight vehicles). Thus, in effect, the closed cargo transport unit is the casing for a very large lithium battery. These battery systems are used in a variety of electric grid and similar applications, such as storage of energy generated by farms of large wind turbines, and also as a source for emergency power’’. 
This proposed special provision 
which captures many of the safety elements included in previous approvals issued by PHMSA would specify that the lithium batteries must meet the requirements of § 173.185(a) and contain the necessary systems to prevent overcharge and over discharge between the batteries. The batteries inside the cargo transport unit are not subject to marking or labelling requirements of part 172 subparts D and E of this subchapter. The cargo transport unit shall display the UN number in a manner in accordance with § 172.332 of this subchapter and be placarded on two opposing sides. 
The batteries must be securely 
attached to the interior structure of the cargo transport unit (e.g., by means of 
placement in racks, cabinets, etc.) in such a manner as to prevent short circuits, accidental operation, and significant movement relative to the cargo transport unit under the shocks, loadings, and vibrations normally incidental to transport. Further, hazardous materials necessary for the safe and proper operation of the cargo transport unit (e.g., fire extinguishing 
systems and air conditioning systems), must be properly secured to or installed in the cargo transport unit and are not otherwise subject to this subchapter. Lastly, hazardous materials not necessary for the safe and proper operation of the cargo transport unit must not be transported within the 
cargo transport unit. 
•Special provision 391. As part of 
the classification and packaging framework for ‘‘Articles containing dangerous goods’’ proposed in this rulemaking, PHMSA proposes to add new special provision 391, which prohibits articles containing certain high-hazard materials of Division 2.3, Division 4.2, Division 4.3, Division 5.1, Division 5.2, or Division 6.1 (substances with a inhalation toxicity of Packing Group I) and articles containing more than one of the following hazards from being offered for transport or transported, except under conditions approved by the Associate Administrator for Hazardous Materials Safety: (1) Gases of Class 2; (2) Liquid desensitized explosives of Class 3; or (3) Self-reactive substances and solid desensitized explosives of Division 4.1. 
•Special provision 422. PHMSA 
proposes revising special provision 422 to remove the transition period authorizing lithium battery Class 9 labels conforming to requirements in place on December 31, 2016 to continue to be used until December 31, 2018. 
•Special provision A56. Special 
provision A56 prescribes requirements for radioactive materials with subsidiary hazards when transported by aircraft. In this NPRM, PHMSA proposes to revise special provision A56 consistent with the revisions made to special provision A78 in the 2019–2020 ICAO Technical Instructions. Specifically, the revisions provide guidance for when the subsidiary risk of a radioactive material is explicitly forbidden for transport on either a passenger or cargo-only aircraft. 
•Special provision A105. PHMSA 
proposes to revise special provision A105, which prescribes requirements for the air transport of machinery or apparatus containing hazardous materials as an integral element of the machinery or apparatus. Where the quantity of hazardous materials contained as an integral element in machinery or apparatus exceeds the limits permitted for air transport in § 173.222, and the hazardous materials meet the provisions of § 173.222 for other than air transport, the machinery or apparatus may be transported by aircraft only with the prior approval of the Associate Administrator for Hazardous Materials Safety. 
•Special provision B136. Consistent 
with the 20th Revised Edition of the UN Model Regulations, PHMSA proposes to add new special provision B136 that authorizes non-specification closed bulk bins for the following solid substances: 
UN1363 Copra 
UN1386 Seed cake, containing 
vegetable oil solvent extractions and expelled seeds, with not more than 10 percent of oil and when the amount of moisture is higher than 11 percent, with not more than 20 percent of oil and moisture combined 
UN1398 Aluminum silicon powder, 
uncoated

•Portable tank special provisions 
PHMSA proposes to revise Portable 
Tank Special Provision TP10 to authorize a three-month extension for the transportation of bromine portable tanks for the purposes of performing the next required test—after emptying, but before cleaning. 
•Special provisions W31 and W32. 
Special provision W32 currently requires non-bulk packagings to be hermetically sealed, except for solid fused material. Amendment 39–18 of the IMDG Code removed the qualifying text from the equivalent special packaging provision. Discussions at the International Maritime Organization noted that when a substance evolves in contact with water flammable gases at the rate and quantity meeting the classification requirements for a Division 4.3 material, that there is no safety justification to permit their transportation in packagings which are not hermetically sealed. In Amendment 39–18, the text ‘‘except for solid fused material’’ was removed from special packing provision PP31 in packing instruction P403. PHMSA agrees, and in this NPRM we are proposing deleting special provision W32 and assigning W31, which requires non-bulk packagings to be hermetically sealed regardless of the form of the material. 
•Special provision W40. Special 
provision W40 prohibits the use of non- bulk bags. This requirement typically applies to solid substances in Packing Group II. Consistent with changes made in Amendment 39–18 of the IMDG Code, PHMSA is proposing that Special provision W40 be removed from the following HMT entries: 
UN1396/(PG III) Aluminum powder, 
uncoated 
UN1398 Aluminum silicon powder, 
uncoated 
UN1403 Calcium cyanamide with 
more than 0.1 percent of calcium 
carbide 
UN1405/(PG III) Calcium silicide 
U3208/(PG III) Metallic substance, 
water-reactive, n.o.s. 
Additionally, PPHMSA is proposing 
to add special provision W40 to the 
following HMT entries: UN1405/(PG II) Calcium silicide 
UN3208/(PG II) Metallic substance, 
water-reactive, n.o.s. 
Section 172.203 
Section 172.203 prescribes additional 
description requirements for shipping 
papers. In this NPRM, PHMSA proposes to require, in revised § 172.203(o), that the words ‘‘TEMPERATURE CONTROLLED’’ be added to the proper shipping name if not already indicated in the HMT, when appropriate. This proposed amendment would provide notice to those in the transport chain that a material is being offered under temperature control. Additionally, PHMSA proposes to add polymerizing substances to the list of types of materials paragraph (o) additional documentation requirements apply to. 
Section 172.407 
Section 172.407 prescribes 
specifications for hazard 
communication labels. Consistent with changes made in Amendment 39–18 of the IMDG Code and the 2019–2020 ICAO Technical Instructions, PHMSA is proposing to amend paragraph (c)(1) to remove the requirement that the width of the solid line forming the inner border of labels must be at least 2 mm. Additionally, we are proposing to amend the requirement that the solid line inner border, currently required to be 5 mm inside and parallel to the edge, to include the word ‘‘approximately’’ before 5 mm. These changes provide flexibility for minor labeling variations that do not have an appreciable impact on transportation safety. Finally, paragraph (c)(1)(iii) which contains a transitional exception allowing for labels in conformance with the requirements of 49 CFR 172.407(c)(1) (revised as of October 1, 2014) to continue to be used until December 31, 2018, is removed and reserved. 
Section 172.514 
Section 172.514 prescribes placarding 
requirements and exceptions for a bulk 
packaging containing a hazardous material. The general placarding requirements prescribe that bulk packagings are to be placarded on each side and each end. Due to the form and shape (e.g., round) of flexible bulk 
containers it is impractical to require placards on each side and each end. Consistent with the IMDG Code, in this NPRM, PHMSA is proposing to allow flexible bulk containers to be placarded in two opposing positions. 
Section 172.604 
Section 172.604 prescribes 
requirements for emergency response telephone numbers. Paragraph (d) 
identifies materials for which an emergency response telephone number is not required when offered for transportation. In a March 30, 2017 final rule [HM–215N; 82 FR 15795], PHMSA harmonized the HMR with international regulations by adopting separate HMT entries for internal combustion engines based on the fuel, i.e., engine, internal 
combustion, flammable liquid powered and engine, internal combustion, flammable gas powered. Previously, a single HMT entry covered all engines. At that time, we did not amend § 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 § 172.604. In this NPRM, PHMSA proposes amending paragraph (d)(2) to list all possible proper shipping names for engines per the original intent. 
Section 172.800 
Section 172.800 prescribes the 
requirements for developing and 
implementing plans to address security risks related to the transportation of hazardous materials in commerce. During review of existing references that are incorporated by reference in the HMR it was noted that the IAEA Code of Conduct Category 1 and 2, while referenced in paragraph (b)(15) was not appropriately incorporated by reference (see § 171.7). In this NPRM, PHMSA is proposing to incorporate by reference the IAEA Code of Conduct on the Safety and Security of Radioactive Sources into paragraph (b)(15). Furthermore, we are proposing to revise a reference to known radionuclides in forms listed as RAM– QC by the Nuclear Regulatory Commission, to Nuclear Regulatory Commission, Category 1 and Category 2 radioactive materials as listed in Table 1, Appendix A to 10 CFR part 37. Lastly, we are listing the reference to Highway Route Controlled Quantities separately in this paragraph. This proposed amendment does not require the creation and retention of security plans by any new individuals, but simply incorporates by reference the appropriate IAEA reference and clarifies the existing requirement. 
Part 173 Section 173.2a 
Section 173.2a outlines classification 
requirements for materials having more 
than one hazard. PHMSA is proposing to amend paragraph (a) to indicate the appropriate classification precedence for the new ‘‘Articles’’ HMT entries

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

Section 173.62 
Section 173.62 outlines specific 
packaging requirements for explosives. 
In paragraph (c), in the Table of Packing Methods, Packing Instruction US 1 containing packing instructions for jet perforating guns, PHMSA is proposing to increase the maximum authorized amount of explosive contents per tool pallet and cargo vessel compartment from 90.8 kg to 95 kg. These limits are consistent with a provision added to Amendment 39–18 of the IMDG Code authorizing jet perforating guns to be 
transported to or from offshore oil platforms, mobile offshore drilling units, and other offshore installations in 
offshore well tool pallets, cradles, or baskets. PHMSA notes that the amendments adopted in section 7.1.4.4.5 of Amendment 39–18 of the IMDG Code require both ends of jet perforating guns to be protected by means of steel end caps. PHMSA is not proposing to adopt this additional requirement for steel end caps noting the safe transportation record of these explosive articles under the existing requirements of the HMR. 
Section 173.121 
Section 173.121 provides criteria for 
the assignment of packing groups to Class 3 materials. Paragraph (b) provides 
criteria for viscous flammable liquids of Class 3 (e.g., paints, enamels, lacquers, 
and varnishes) to be placed in packing group III on the basis of their viscosity, coupled with other criteria. Consistent with recent changes to the IMDG Code, PHMSA is proposing to amend paragraph (b)(1)(iii) to authorize a packaging capacity up to 450 L (119 gallons), an increase from the presently authorized 30 L. A working paper submitted to the IMO Sub-Committee on 
Carriage of Cargoes and Containers (CCC), noted that both the UN Model Regulations and The European Agreements Concerning the 
VerDate Sep<11>2014 18:40 Nov 26, 2018 Jkt 247001 PO 00000 Frm 00019 Fmt 4701 Sfmt 4702 E:\FR\FM\27NOP2.SGM 27NOP2amozie on DSK3GDR082PROD with PROPOSALS260988 Federal Register / Vol. 83, No. 228 / Tuesday, November 27, 2018 / Proposed Rules 
International Carriage of Dangerous 
Goods by Road (ADR) and Rail (RID) allow receptacles up to 450 L, and that due to the nature of viscous materials (e.g. lower flow rate in the event of 
damage to a receptacle, and lower levels of solvent vapors) which present a lower fire risk than non-viscous flammable liquids there has been a history of safe transport of these materials by road and rail since the introduction of the provision. The working paper also explained that: 
Recognizing that global transport of 
dangerous goods is inherently multi-modal, 
the harmonization of the IMDG Code with other modes will aid trade and reduce incidents of non-compliance due to misunderstandings. At the point of packing, 
the manufacturer will not know which route (by road/rail/inland waterway or sea) the package will take. This leads to the possibility of accidental consignment by sea of packages between 30 and 450 litres. 
This proposed change would increase 
the allowed volume of viscous liquids 
in a single package and would be applicable to all modes except for air. Specifically, in this NPRM, PHMSA is proposing to increase the packaging limits for viscous flammable liquids of packing group II material that may be placed in packing group III. For transport by vessel, PHMSA proposes an increase from 30 L to 450 L. For transport by rail and highway, PHMSA proposes an increase from 100 L to 450 L. Consistent with the ICAO Technical Instructions, the packaging quantity limits to air will remain 30 L for passenger aircraft and 100 L for cargo aircraft. 
Section 173.124 
Section 173.124 contains definitions 
for Class 4, Divisions 4.1, 4.2, and 4.3. 
In this NPRM, PHMSA is proposing to amend paragraph (a)(4)(iv) to extend the sunset dates for provisions concerning the transportation of polymerizing substances from January 2, 2019, to January 2, 2021. See the background section of this rulemaking for a more detailed discussion on polymerizing substances. 
Section 173.127 
Section 173.127 provides a definition 
and criteria for the assignment of 
packing groups for Division 5.1 Oxidizers. A new Section 39 in the UN Manual of Tests and Criteria was introduced containing all provisions for the classification of ammonium nitrate based fertilizers. As a consequence of the new section, existing text in both the Manual and the Model Regulations was amended or removed to avoid duplicative provisions in both publications. In this NPRM, PHMSA is 
proposing to revise the classification criteria for solid ammonium nitrate based fertilizers by requiring that they are classified in accordance with the procedures prescribed in the UN Manual of Tests and Criteria, Part III, Section 39. These proposed changes are not intended to result in changes to the current classification provisions for ammonium nitrate fertilizers, but rather consolidate the provisions for ease of use and prevent inadvertent 
misclassification. 
Section 173.134 
Section 173.134 provides definitions 
and exceptions for infectious 
substances. Consistent with the UN Model Regulations, PHMSA is proposing to revise the definition for ‘‘patient specimen’’ in paragraph (a)(4) by removing redundant references to humans and animals. 
Section 173.136 
Section 173.136 provides the 
definition for corrosive materials. In the 
UN Model Regulations, the definition for corrosive materials was revised to align with the current text in Chapter 3.2 of the UN GHS and the Organization for Economic Cooperation and Development (OECD) Test Guidelines for Testing of Chemicals. PHMSA is proposing to amend the definition in paragraph (a) for a corrosive material by replacing the text ‘‘full thickness destruction’’ with ‘‘irreversible damage.’’ 
Section 173.137 and Appendix I to Part 
173 
Section 173.137 prescribes the 
requirements for assigning a packing group to Class 8 materials. Currently the HMR require offerors to classify Class 8 corrosive material and assign a packing group based on test data. The HMR authorize a skin corrosion test and various in vitro test methods that do not 
involve animal testing. However, data obtained from either currently authorized test is generally the only data acceptable for classification and assignment of a packing group. In this NPRM, consistent with changes to the UN Model Regulations, PHMSA proposes to include alternative packing group assignment methods for making a corrosivity classification determination for mixtures that do not involve testing. These proposed amendments include bridging principles and a calculation method for the classification of mixtures. 
In a new paragraph (d), PHMSA 
proposes creating an alternative, tiered approach to classification and packing group assignment depending on how 
much information is available about the mixture itself, similar mixtures, and/or the mixture’s ingredients. When sufficient data is available on similar mixtures to estimate skin corrosion hazards for bridging, the bridging principle method may be used to classify and assign a packing group. When no bridging data is available, the more conservative calculation method may be used. This tiered approach ensures an appropriate level of safety in situations where reliable data may not be available. These alternatives for classifying corrosive mixtures allow offerors the ability to make a classification and packing group assignment without having to conduct physical tests. 
Additionally, the new corrosivity 
classification methods are much more closely aligned with those found in the UN GHS. However, not all GHS corrosivity classification methods were incorporated in the new UN Model Regulations corrosivity requirements. For example, the use of extreme pH values to assign corrosivity were not addressed in the UN Model Regulations, and as such are not proposed in this NPRM. Consistent with the proposed change to the definition of a corrosive material in § 173.136, PHMSA is proposing to replace all instances of the text ‘‘full thickness destruction’’ with ‘‘irreversible damage.’’ PHMSA is also proposing to add a new appendix I to part 173, containing a flow chart for use with the calculation method. 
Finally, PHMSA is proposing to 
update the four existing OECD Guidelines currently incorporated by reference in this section to their 2015 versions (Test Nos. 404, 430, 431, and 435). OECD Guideline 404 and OECD Guideline 435 contain minor variations 
in the types of information to be recorded as a part of the test report in relation to the previously incorporated versions. OECD Guideline 430 and OECD Guideline 431 were updated to include a reference to a developed document on integrated approaches to testing and assessment. OECD Guideline 431. 
Section 173.159 
Section 173.159 prescribes 
requirements applicable to the 
transportation of electric storage batteries containing electrolyte acid or alkaline corrosive battery fluid (i.e., wet 
batteries). Consistent with the UN Model Regulations, PHMSA is proposing several editorial amendments in paragraphs (a) and (d) to specify that electrically non-conductive packaging materials must be used and that contact

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

doc/2016/dgac10c3/ST-SGAC.10-C.3-2016-82e.pdf. (2) the lithium battery mark must also 
be affixed on the outside of the overpack, and the overpack must be marked with the word ‘‘OVERPACK’’ in lettering at least 12 mm (0.47 inches) high. PHMSA proposes to amend § 173.185(c)(4)(ii) to adopt an ‘‘OVERPACK’’ marking minimum size requirement consistent with the proposed requirement for surface transport in § 173.185(c)(3)(iii). PHMSA proposes to clarify the limits for spare batteries in § 173.185(c)(4)(iv) to state that up to ‘‘two spare sets’’ of cells or batteries can be placed in a package with equipment. For the purposes of this paragraph, a spare set is equal to the number of individual spare cells or batteries required to power each piece of equipment. For example, if a single item of equipment requires two lithium batteries to operate, a maximum of four additional batteries (two spare sets) may be placed in the package provided the package continues to meet the other conditions of § 173.185(c). PHMSA proposes to add a new § 173.185(c)(4)(v) to specify that for air transport, lithium cells and batteries may not be placed in the same package as other hazardous materials. Further, packages containing small lithium cells and batteries must not be placed into an overpack with packages containing Class 1 (explosives) other than Division 1.4S, Division 2.1 (flammable gases), Class 3 (flammable liquids), Division 4.1 (flammable solids) or Division 5.1 (oxidizers). Each of the remaining sub-paragraphs in § 173.185(c)(4) would be renumbered and remain unchanged. PHMSA is proposing this action to promote consistency with the ICAO Technical Instructions and in response to a recommendation (A–16–001) from the National Transportation Safety Board (NTSB) stemming from the investigation of the July 28, 2011, in-flight fire and crash of Asiana Airlines Flight 991 that resulted in the loss of the aircraft and crew. The investigation report cited as a contributing factor the flammable materials and lithium ion batteries that were loaded together either in the same or adjacent pallets. Logically, if the materials are not allowed to be stowed in the same or adjacent pallets, segregation within the same package also would result in decreased risk in the event of a fire. 
Section 173.185(d) of the HMR 
describes provisions for the transport of lithium cells and batteries for disposal or recycling. In this NPRM, PHMSA proposes to authorize the use of certain rigid large packagings to transport a single large battery or a single large item of equipment. This will provide additional packaging options to 
transport large batteries and equipment that by nature of their size or shape cannot fit into a non-bulk package. The UN Model Regulations do not include large packagings as an option for lithium batteries shipped for disposal or recycling. Nevertheless, PHMSA expects that large batteries and equipment would potentially require large packagings. Like the authorizations for the use of large packagings elsewhere in § 173.185, PHMSA would authorize the use of a large packaging for a single large battery or a single item of equipment containing batteries. PHMSA proposes to separate the existing § 173.185(d) into separate subparagraphs (d)(1) and (2) to accommodate these amendments. 
Section 173.185(e) of the HMR 
describes provisions for the transport of low production and prototype lithium cells and batteries including equipment. In this NPRM, PHMSA proposes an editorial amendment to the § 173.185(e) introductory paragraph to clarify that the ‘‘transported for purposes of testing’’ condition applies to prototype cells and batteries and that both low production and prototype lithium cells and batteries may be contained in equipment. PHMSA also proposes an editorial amendment to paragraphs (e)(1) and (2) to specify that cushioning material must be electrically non- conductive instead of the existing ‘‘non- conductive’’ requirement. In addition, PHMSA proposes a new paragraph (e)(4) to authorize the use of certain rigid large packagings to transport a single large battery or a single large item of equipment. This will provide additional packaging options to transport large batteries and equipment that by nature of their size or shape cannot fit into a non-bulk package. Each of the remaining sub-paragraphs in § 173.185(e) would be renumbered and remain unchanged. 
Section 173.185(f) of the HMR 
describes provisions for the transport of lithium batteries that have been damaged or identified by the manufacturer as being defective for safety reasons, and that have the potential of producing a dangerous evolution of heat, fire, or short circuit (e.g., those being returned to the 
manufacturer for safety reasons). PHMSA proposes an editorial amendment to § 173.185(f)(2) to specify that cushioning material must be electrically non-conductive, which would harmonize the HMR with the international standards. PHMSA also proposes to amend § 173.185(f)(3) to 
clarify the provisions for the use of large packagings. Currently, large packagings are authorized for the transport of a single battery including a battery contained in equipment. This amendment would clarify that large packagings are limited to a single battery and to a single item of equipment. This acknowledges that a single item of equipment may contain one or more batteries. 
Section 173.218 
Section 173.218 contains packaging 
requirements for shipments of stabilized 
fish meal and fish scrap. Stabilization of fish meal and fish scrap by applying antioxidants is required in order to offer the material under a Class 9 stabilized proper shipping name. Historically, the IMDG Code and the HMR only reference one antioxidant—ethoxyquin—by name although other antioxidants exist. In response to testing performed by the International Fishmeal and Fish Oil Organization (IFFO)
5that indicated that 
of concentrations of 50 ppm (mg/kg) of ethoxyquin, 100 ppm (mg/kg) of butylated hydroxytoluene (BHT), and 250 ppm (mg/kg) of tocopherol-based antioxidant are effective in stabilizing fish meal, the UN and the IMO adopted allowances for the use of two additional antioxidants (butylated hydroxytoluene and tocopherols) and a reduction in the required ethoxyquin concentration at time of shipment from 100 ppm to 50 ppm. 
In this NPRM, PHMSA is proposing to 
amend paragraph (c) of this section to lower the required ethoxyquin level at the time of shipment in bulk in freight containers for transportation by vessel from 100 ppm to 50 ppm and to specify acceptable levels of for butylated hydroxytoluene (100 ppm) and for tocopherols (250 ppm) in shipments of fish meal or fish scrap transported by vessel in bulk in freight containers. Reducing the required minimum concentration of ethoxyquin and permitting the use of additional antioxidants would potentially reduce cost, add flexibility while maintaining an equivalent level of safety. 
Section 173.220 
Section 173.220 prescribes 
transportation requirements and 
exceptions for internal combustion engines, vehicles, machinery containing internal combustion engines, battery- powered equipment or machinery, and fuel cell-powered equipment or machinery. 
Special provision 135 is assigned to 
the HMT entries for certain vehicles. It specifies that if a vehicle is powered by

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

because during the early development 
phase of a new product, complete test data is often unavailable but the substances must be transported for further testing. The provisions proposed in paragraph (c)(4) prescribe applicability criteria and packaging conditions for these substances to be transported as samples for the purpose of testing. These criteria and packaging conditions are based on submissions to the UNSCOE on the Transport of Dangerous Goods showing the effectiveness of the packaging method proposed in this NPRM. 
Consistent with the UN Model 
Regulations, PHMSA is proposing to revise paragraph (b)(4) to authorize the transportation of self-reactive substances packed in accordance with packing method OP8 (non-bulk packaging authorization) where transport in IBCs or portable tanks is permitted in accordance with § 173.225, provided that the control and emergency temperatures specified in the instructions are complied with. This proposed change allows materials that are authorized in bulk packagings to also be transported in appropriate non- bulk packagings. 
Section 173.225 
Section 173.225 prescribes packaging 
requirements and other provisions for 
organic peroxides. The UN Model Regulations continually update their Organic Peroxide Table based on data submitted by governments and industry groups with consultative status to account for new peroxides and formulations that have become commercially available. Consistent with revisions to the UN Model Regulations, PHMSA proposes to revise the Organic Peroxide Table in paragraph (c) by adding the entries: ‘‘Di-(4-tert- butylcyclohexyl)peroxydicarbonate [as a paste],’’ ‘‘Diisobutyryl peroxide [as a stable dispersion in water],’’ and ‘‘1- Phenylethyl hydroperoxide.’’ We propose to revise the Organic Peroxide IBC Table in paragraph (e) to maintain alignment with the UN Model Regulations by adding new entries for ‘‘Cumyl peroxyneodecanoate, not more than 52%, stable dispersion, in water,’’ ‘‘2,5-Dimethyl-2,5-di(tert- butylperoxy)hexane, not more than 52% in diluent type A,’’ ‘‘3,6,9-Triethyl- 3,6,9-trimethyl-,4,7-triperoxonane not more than 27% diluent type A,’’ and ‘‘tert-Amyl peroxy-2-ethylhexanoate, not more than 62% in a diluent type A’’ and by adding a type 31HA1 IBC authorization to the existing entry for ‘‘tert-Butyl hydroperoxide, not more than 72% with water.’’ In addition, consistent with the UN 
Model Regulations, PHMSA is 
proposing that organic peroxides may also be transported packed in accordance with packing method OP8 where transport in IBCs or portable tanks is permitted, provided that the control and emergency temperatures specified in the instructions are complied with. 
Section 173.232 
New section 173.232 prescribes 
requirements for articles not otherwise 
specified by name in the HMR that contain hazardous materials of various hazard classes and divisions. This proposal addresses situations in which hazardous materials or hazardous materials residues are present in articles in quantities greater than the amounts authorized for dangerous goods in machinery or apparatus. This proposal authorizes a safe method to transport 
articles that may be too large to fit into typical packages. Absent these provisions to package and transport these materials safely, these articles may be offered for transport under provisions that do not adequately account for the physical and chemical properties of the substances and may require the issuance of an approval by PHMSA’s Associate Administrator for Hazardous Materials Safety. PHMSA believes this will be especially beneficial to new articles coming to market as they would no longer require an approval or an amendment to the Hazardous Materials Table to authorize transport. 
Section 173.301b 
Section 173.301b describes additional 
requirements when shipping gases in 
UN pressure receptacles. In paragraph (c)(1), PHMSA is proposing to incorporate ISO 17871:2015 containing specification and type testing requirements for quick release cylinder valves. In paragraph (d)(1), PHMSA is phasing out ISO 13340:2001, Transportable gas cylinders—Cylinder valves for non-refillables cylinders— Specification and prototype testing, which can be utilized until December 31, 2020. ISO 13340:2001 is being phased out because the applicable valve standard in ISO 13340:2001 has been incorporated into ISO 11118:2015. 
Section 173.304b 
Section 173.304b contains additional 
requirements for shipment of liquefied 
compressed gases in UN pressure receptacles. In this NPRM, consistent with a change made by in the 20th Revised Edition of the UN Model Regulations, PHMSA is proposing to amend paragraph (b)(5) by replacing ‘‘liquid phase’’ with ‘‘liquefied gas’’ and ‘‘compressed’’ with ‘‘compressed gas’’ to better describe the phases of the material being stored and to align with the UN language. 
Section 173.422 
Section 173.422 contains additional 
requirements for excepted packages 
containing Class 7 (radioactive) materials. Shipments of excepted packages containing Class 7 materials are not required to meet the general shipping paper requirements found in the HMR. Amendments 39–18 of the IMDG Code adopted a requirement that vessels carrying these excepted packages include information concerning these packages (e.g., UN ID 
Number and location on board the vessel) on the Dangerous Cargo Manifest (DCM). Historically, the HMR has not required any documentation to accompany shipments of excepted packages containing radioactive material when offered for transportation by vessel. In this NPRM, PHMSA proposes to amend the DCM requirements in § 173.60 to require information about these shipments to be included in the DCM carried aboard the vessel. Without a corresponding amendment to § 173.422 to require the information to be provided to the vessel operator, the vessel operator would not have the information available that would be required to be included on the DCM. 
In this NPRM, PHMSA proposes to 
add a new paragraph (f) that would require excepted packages of radioactive materials offered for transportation by vessel to have a special transport document such as a bill of lading, air waybill, or other similar document that includes the UN identification number for the material being offered, the name and address of the consignor and consignee, and a container packing certificate, in accordance with the requirements in § 176.27. This proposed amendment provides for the conveyance of necessary information to the vessel operator for creation of the DCM. 
Part 174 Section 174.50 
Section 174.50 prescribes regulations 
for the movement of nonconforming or 
leaking packages by rail. Under the HMR, no person may offer for transportation or transport a bulk hazmat packaging (typically a tank car) by rail unless that packaging is marked, represented, maintained, reconditioned, repaired, and retested in accordance with the HMR (§ 171.2(g)). However, § 174.50 authorizes the movement of a

Approvals issued by FRA’s Associate 
Administrator for Railroad Safety are commonly referred to as One-Time Movement Approvals (OTMAs).

Transport Canada issues similar approvals for the movement of non- conforming bulk hazmat packages and tank cars, which are referred to as Temporary Certificates. Historically, for movements of non-conforming tank cars from Canada to or through the United States, the offeror would have to obtain 
both an OTMA from FRA and a Temporary Certificate from Transport Canada. These applications initiate administrative processes and safety reviews by both governments that nearly always result in the same conclusion. Since the safety analysis used to evaluate Temporary Certificates in Canada is similar to the safety analysis used to evaluate OTMAs by FRA, the requirement to obtain two government approvals for a cross border movement provides no additional safety benefit and is redundant and burdensome. Thus, to facilitate cross border trade, for movements to or through the United States from Canada, PHMSA proposes to amend the regulation to recognize Temporary Certificates issued by Transport Canada. This amendment would reduce the duplicative requirement to apply for both an OTMA from the United States and a Temporary Certificate from Canada, should the non- conforming package need to be transported over the United States- Canadian border. 
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 § 171.12, provided the movements are compliant with all applicable requirements in the TDG Regulations and § 171.12. 
Part 175 Section 175.10 
Section 175.10 specifies the 
conditions for which passengers, crew 
members, or an operator may carry hazardous materials aboard an aircraft. Consistent with revisions to the ICAO Technical Instructions, in this NPRM, PHMSA is proposing several revisions to this section. 
PHMSA proposes to revise paragraph 
(a)(2) to account for lighters powered by lithium batteries (e.g., laser plasma 
lighters, tesla coil lighters, flux lighters, arc lighters, and double arc lighters). The assigned provisions would be consistent with a combination of the existing requirements applicable to portable electronic devices powered by lithium batteries and battery powered portable electronic smoking devices. Specifically, each lithium battery must be of a type which meets the requirements of each test in the UN Manual of Tests and Criteria, Part III, Subsection 38.3 and must not exceed the size limits authorized for portable electronic devices. Recharging of the devices and/or the batteries on board the aircraft is not permitted consistent with the requirements for portable electronic smoking devices. In addition, lithium battery powered lighters without a safety cap or means of protection against unintentional activation are prohibited in carry-on baggage, checked baggage, and as when carried on one’s person. 
PHMSA proposes to revise paragraph 
(a)(3), to authorize medical devices containing radioactive material fitted externally as the result of medical treatment, consistent with the ICAO Technical Instructions. In addition, the reference to implanted medical devices containing lithium batteries would be removed. For medical devices containing lithium batteries (including those implanted, externally fitted, or carried by passengers or crew members) the quantity limits provided in (a)(18)(i) or (ii) apply, as applicable. 
PHMSA proposes to revise paragraph 
(a)(14) for consistency with the ICAO Technical Instructions and other paragraphs in this section. The first sentence is revised to clarify that the paragraph is applicable to battery powered heat-producing devices rather than ‘‘electrically powered’’ articles. For lithium battery powered devices, quantity limits would be added in new 
paragraphs (i) and (ii) consistent with the existing requirements applicable to portable electronic devices powered by lithium batteries and battery powered portable electronic smoking devices. The requirements for spare batteries would be revised to reference the provisions for spare batteries in paragraph (a)(18). 
PHMSA proposes to revise paragraph 
(a)(15) by adding a new paragraph (vi) to separate and clarify the handling requirements applicable to each ‘‘non- spillable’’ and ‘‘dry sealed’’ batteries both presently prescribed in paragraph (v). PHMSA also proposes to add a new paragraph (vii) to authorize passengers with restricted mobility to carry a spare non-spillable or dry sealed battery for their mobility aid. Presently, spare lithium batteries are permitted for passengers with lithium battery- powered mobility aids; this was deemed acceptable for mobility aids equipped with non-spillable or dry sealed batteries. 
PHMSA proposes to amend 
provisions for carriage of wheelchairs or other mobility aids equipped with a lithium ion battery by removing the requirement that ‘‘collapsible’’ mobility aids necessitate removal of the battery. The intent of the existing requirement was to allow the removal of the batteries from lightweight collapsible mobility aids when these do not afford any protection to the batteries. However, the existing text in both the HMR and ICAO Technical Instructions can be construed to mean that if the battery was designed to be removable from the mobility aid, that it must be removed in all circumstances, even when adequate protection to the batteries is provided. In cases when the batteries are adequately protected, it is preferable that they remain installed in the mobility aid; however, there may be situations when that is not possible or safe to do so and in these cases the batteries must be removed. Therefore, in this NPRM, PHMSA is proposing to amend (a)(17)(v) by removing the word ‘‘collapsible’’ and clarifying that when the wheelchair or mobility aid does not provide adequate protection to the battery, that the battery must be removed and handled in accordance 
with the existing conditions prescribed in (a)(17)(v)(A) through (E). 
PHMSA proposes to amend the 
provisions for carriage of personal electronic devices (PEDs) containing lithium batteries to address safety concerns related to recent security restrictions requiring passengers to carry personal electronic devices in checked baggage. Consistent with the ICAO

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

crew. The investigation report cited as 
a contributing factor the flammable materials and lithium ion batteries that were loaded together either in the same or adjacent pallets. 
Part 176 Section 176.30 
Section 176.30 prescribes 
requirements for DCM’s, lists, or 
stowage plans required to be carried aboard vessels transporting hazardous materials. In this NPRM, PHMSA is proposing to add a new paragraph (a)(9) to require that DCMs include information on shipments of excepted packages containing Class 7 materials. For shipments of excepted packages containing Class 7 material only the UN identification number, the name and address of the consignor and the consignee, and the stowage location of the hazardous material on board the vessel would be required to be entered on the DCM, list, or stowage plan carried aboard the vessel. 
Section 176.84 
Section 176.84 prescribes the 
meanings and requirements for 
numbered or alphanumeric stowage provisions for vessel shipments listed in column (10B) of the § 172.101 HMT. The provisions in § 176.84 are broken down into general stowage provisions, which are defined in the ‘‘table of provisions’’ in paragraph (b), and the stowage provisions applicable to vessel shipments of Class 1 explosives, which are defined in the table in paragraph (c)(2). In a previous final rule [Docket No. PHMSA–2015–0273 (HM–215N); 82 FR 15796], a subsidiary hazard of 6.1 was added to the UN 2977 and UN 2978 uranium hexafluoride entries, and the primary hazard for UN 3507, Uranium hexafluoride, radioactive material, excepted package was changed from 8 to 6.1. Consequential amendment to the stowage and segregation requirements codes for these materials were not addressed at the time of these changes in the IMDG Code or the HMR. In this NPRM, we propose to create new stowage provisions that clarify what segregation requirements apply to shipments of uranium hexafluoride. 
PHMSA proposes to create a new 
stowage provision 151 and assign it to the UN 2977 and UN 2978 uranium hexafluoride entries. This new stowage provision will require segregation for Class 7 materials to apply to uranium hexafluoride shipped under these two UN numbers. 
Additionally, consistent with 
Amendment 39–18 of the IMDG Code, PHMSA proposes to create a new stowage provision 152 and assign it to UN 3507, Uranium hexafluoride, radioactive material, excepted package. This proposed new stowage provision requires segregation as for Class 8, but excepts segregation in relation to Class 7 materials. This exception to the general segregation requirements between Class 8 and Class 7 materials allows shipments of excepted packages of uranium hexafluoride to be stowed in close proximity to shipments of fully regulated uranium hexafluoride. 
Based on changes to the IMDG Code 
to address the appropriate segregation requirements for shipments of uranium hexafluoride, PHMSA proposes to create a new stowage provision 153 and assign it to the UN 2977 and UN 2978 uranium hexafluoride HMT entries. This proposed new stowage provision requires these materials to be stowed ‘‘separated longitudinally by an intervening complete compartment or hold from’’ Divisions 1.1, 1.2, and 1.5. 
Based on changes to the IMDG Code 
to provide additional flexibility in the stowage requirements for jet perforating guns, PHMSA proposes to create a new stowage provision 154 and assign it to the NA 0123, NA 0494, UN 0494, and UN 0124 jet perforating gun HMT entries. This proposed new stowage provision indicates that, notwithstanding the stowage category assigned to the entries in the HMT, jet perforating guns may be stowed in accordance with the provisions of packing instruction US 1 in § 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 § 173.62 are not required to be offered for transport or transported in closed cargo transport units. 
Part 178 Section 178.71 
Section 178.71 prescribes 
specifications for UN pressure 
receptacles. Consistent with the UN Model Regulations, PHMSA proposes to amend paragraphs (d)(2), (i), (j), and (q)(12), to reflect the adoption of the latest ISO standards for the design, construction, and testing of gas cylinders and their associated service equipment. In paragraph (d)(2), PHMSA is proposing to phase out ISO 13340:2001, which is authorized for valves manufactured until December 31, 2020, and to incorporate by reference ISO 14246:2014 (E) ‘‘Gas cylinders— Cylinder valves—Manufacturing tests 
and examination’’, which addresses initial inspection and testing requirements for valves. ISO 13340:2001 is being phased out because the applicable valve has been incorporated into ISO 11118:2015. In paragraph (f), PHMSA is proposing to amend the title of the paragraph to include pressure drums and to add ISO 21172–1:2015(E), ‘‘Gas cylinders—Welded steel pressure drums up to 3 000 litres capacity for the transport of gases—Design and construction—Part 1: Capacities up to 1 000 litres’’ in new paragraph (f)(4). A note was added to the UN Mode Regulations that authorizes welded steel gas pressure drums with dished ends convex to pressure to be used for the transport of corrosive substances provided all applicable additional requirements are met, irrespective of section 6.3.3.4 of this standard which prohibits such use. Therefore, PHMSA is proposing the same deviation from the ISO standard in (p). 
In addition, in paragraph (i), PHMSA 
is proposing to phase out ISO 11118:1999 ‘‘Gas Cylinders for Non- refillable Metallic Gas Cylinders,’’ which is authorized until December 31, 2022, and to replace it with new standard, ISO 11118:2015. In paragraph (j), PHMSA is proposing to phase out ISO 111120:1999, ‘‘Gas Cylinders for Refillable Seamless Steel Tubes,’’ which is authorized until December 31, 2022, and to replace it with ISO 111120:2015. 
In paragraph (q)(12), PHMSA is incorporating ISO/TR 11364, ‘‘Gas cylinders—Compilation of national and international valve stem/gas cylinder neck threads and their identification and marking system’’ to specify a harmonized identification code and marking system for both cylinders and valves. 
Section 178.75 
Section 178.75 prescribes 
specifications for MEGCs. In paragraph 
(d)(3)(v), PHMSA is proposing to phase out ISO 11120:1999, which is authorized for construction and testing of receptacles of MEGCs until December 31, 2020, and to authorize the new, updated standard ISO 11120:2015. Changes to the new edition of this standard include the addition of an annex outlining typical chemistry groupings for seamless steel tubes, the addition of nickel chromium molybdenum steel, the modification of ultrasonic examination provisions, and revisions to the provisions for the design of tubes for embrittling gases.

7Amendment 39–18 to the IMDG Code may be 
voluntarily applied on January 1, 2019; however, 
the previous amendment remains effective through December 31, 2019. Section 178.601 
Section 178.601 prescribes the general 
requirements for test procedures for 
non-bulk packagings and packages. A test report must be prepared and made available to a user of a packaging or a DOT representative upon request. In this NPRM, PHMSA is proposing to require in paragraph (l)(2)(viii) that the test report for plastic packagings that are subject to the hydraulic pressure test must include the temperature of the water used for the test. Tests with different water temperatures applied to one design type can produce different test results (pass or fail). This action is consistent with amendments to the UN Model Regulations. 
Section 178.801 
Section 178.801 prescribes the general 
requirements for test procedures of an 
IBC containing a hazardous material. A test report for an IBC must be prepared and made available to a user of a packaging or a DOT representative upon request. In this NPRM, PHMSA is proposing to require in paragraph (l)(2)(viii) that the test report for rigid plastics and composite IBCs that are subject to the hydraulic pressure test must include the temperature of the water used for the test. Tests with different water temperatures applied to one design type can produce different test results (pass or fail). The inclusion of the temperature of the water used for the test will allow for tests that more accurately simulate the original design type testing when such additional testing is performed. 
Section 178.810 
Section 178.810 prescribes the 
requirements for an IBC drop test. In 
paragraph (c)(1), PHMSA proposes to clarify that the same IBC or a different IBC of the same design type may be utilized for the required drop tests. 
Part 180 Section 180.207 
Section 180.207 prescribes 
requirements for requalification of UN 
pressure receptacles. In March 2017, PHMSA published a final rule under Docket HM–215N [82 FR 15796 (March 30, 2017)]. In this rule, PHMSA amended the HMR to expand recognition of cylinders and pressure receptacles, cargo tank repair facilities, and certificates of equivalency in accordance with the Transport Canada TDG Regulations. The goal of these amendments is to promote flexibility and permit the use of advanced technology for the requalification and use of pressure receptacles, to provide for a broader selection of authorized 
pressure receptacles, reduce the need for special permits, and to facilitate cross-border transportation of these cylinders. In the HMR in § 171.12 (a)(4) permit the transportation of a cylinder authorized by Transport Canada TDG Regulations to, from, or within the United States. In HM–215N, PHMSA amended (a)(4)(ii) to authorize the use of Canadian manufactured cylinders. Specifically, PHMSA authorized the transportation of CTC, CRC, BTC, and TC cylinders that have a corresponding DOT specification cylinder prescribed in the HMR. HM–215N did not remove or amend existing requirements for DOT specification cylinders; rather, PHMSA is providing that a shipper may use either a DOT specification cylinder or a TC cylinder, as appropriate. 
In this NPRM, PHMSA proposes to 
clarify the amendments in HM–215N and allow for the requalification of ‘‘CAN’’ marked UN cylinders in the United States. Cylinders marked with the letters ‘‘CAN’’ for Canada as a country of manufacture or a country of approval may be requalified in the United States, provided the requirements in §§ 178.69, 178.70, and 178.71, as applicable, are met. This amendment aims to facilitate international transportation, while ensuring the safety of people, property, and the environment 
Consistent with changes to the UN 
Model Regulations, PHMSA proposes to revise paragraph (d)(1) to incorporate ISO 16148:2016, which addresses the requalification of seamless steel cylinders and tubes. This proposed addition will allow the internal inspection and hydraulic pressure test for seamless steel ISO cylinders and tubes to be replaced by non-destructive testing methods identified in ISO 16148:2018. Additionally, in paragraph (d)(4), PHMSA is proposing to phase out ISO 11623:2002, which is authorized for inspection and testing of composite UN cylinders until December 31, 2020, and authorizing the new standard, ISO 11623:2015. Finally, PHMSA proposes adding new paragraph (d)(6) to incorporate inspection and maintenance requirements for cylinder valves preformed during requalification, as found in ISO 22434:2006 ‘‘Transportable gas cylinders— Inspection and maintenance of cylinder valves.’’ Changes to the revised standard include; up-to-date terminology particularly for the various types of composite cylinders, up-to-date normative references for steel and aluminum-alloy liner materials, and an 
update of some photographs to provide sharper examples of damage. VII. Regulatory Analyses and Notices 
A. Statutory/Legal Authority for This 
Rulemaking 
This proposed rule is published under 
the statutory authority of Federal hazardous materials transportation law (49 U.S.C. 5101 et seq.). Section 5103(b) of Federal hazmat law authorizes the Secretary of Transportation to prescribe regulations for the safe transportation, including security, of hazardous materials in intrastate, interstate, and foreign commerce. This proposed rule would amend regulations to maintain alignment with international standards by incorporating various amendments, including changes to proper shipping names, hazard classes, packing groups, special provisions, packaging authorizations, air transport quantity limitations, and vessel stowage requirements. To this end, the proposed rule amends the HMR to more fully align with the biennial updates of the UN Model Regulations, the IMDG Code, and the ICAO Technical Instructions. 
The following external agencies were 
consulted in the development of this rule: 
•Federal Aviation Administration; 
•Federal Motor Carrier Safety 
Administration; 
•Federal Railroad Administration; 
and 
•U.S. Coast Guard. 
Section 49 U.S.C. 5120(b) of Federal 
hazmat law authorizes the Secretary to ensure that, to the extent practicable, regulations governing the transportation of hazardous materials in commerce are consistent with standards adopted by international authorities. This rule proposes to amend the HMR to maintain alignment with international standards by incorporating various amendments to facilitate the transport of hazardous material in international commerce. To this end, as discussed in detail above, PHMSA proposes to incorporate changes into the HMR based on the 20th Revised Edition of the UN Model Regulations, Amendment 39–18 to the IMDG Code
7, and the 2019–2020 
Edition of the ICAO Technical Instructions, which become effective January 1, 2019. The large volume of hazardous materials transported in international commerce warrants the harmonization of domestic and international requirements to the greatest extent possible.

10OSHA’s estimate relied on comparing the costs 
of complying with the revised Hazard Communication Standard to the overall output of hazardous materials. The study measured four cost elements: revisions to labels and safety data sheets, additional training, additional management activities, and printing of color packaging. PHSMA determined that only the first three cost elements were relevant for harmonization purposes, and estimated the value of these costs as a fraction of the total value of hazardous materials produced in the United States to determine the $0.001 per dollar of hazardous materials output. 11Bureau of Economic Analysis, U.S. Department

Order 13563, and DOT Regulatory Policies and Procedures 
This notice is not considered a 
significant regulatory action under section 3(f) of Executive Order 12866 (‘‘Regulatory Planning and Review’’) and, therefore, was not reviewed by the Office of Management and Budget. This notice is not considered a significant rule under the Regulatory Policies and Procedures of the Department of Transportation (44 FR 11034). 
Cost-Reducing Aspects of 
Harmonization 
General Harmonization Benefit: Given 
current available information, PHMSA has developed an estimate of the avoided compliance costs of harmonization, and discusses and requests comment on additional benefits. 
To estimate the benefits to affected 
industries from avoided compliance costs, PHMSA relies on a benefit- transfer value of the hazard communication cost savings utilized in previous PHMSA international harmonization rulemakings
8, based on 
an Occupational Safety and Health Administration (OSHA) study. The original rulemaking harmonized U.S. regulations with international standards so that industry did not have to adhere to two separate hazard communication systems.
9This value—$0.001 per dollar 
of hazardous materials output—is based 
on OSHA’s estimate of the costs for industry to comply with the revised Hazard Communication Standard
10and 
an estimate of the value of hazardous material in trade. The savings then accrue to all exporters, who would otherwise incur theses costs of hazard communication. 
Using this estimate of the avoided 
hazard communication costs, PHMSA estimated the potential benefits to exporters of harmonizing the HMR with international standards. PHMSA relied on the 2012 Bureau of Economic Analysis’ (BEA) International Accounts Products for Detailed Goods Trade Data to value industry imports and exports.
11 
PHSMA updated our estimate of value 
of hazardous materials involved in international trade by using U.S. trade in goods seasonally adjusted, Census- based total gross imports, and gross exports in the fuels and lubricants, chemicals, and medicinal/dental/ pharmaceutical products industries for the 2016, the most recent year available. 
•Gross imports: $343.431 billion. 
ÆFuels and lubricants: $162.077 
billion. 
ÆChemicals: $69.655 billion. 
ÆMedicinal/dental/pharmaceutical 
products: $111.700 billion. 
•Gross exports: $269.518 billion. 
ÆFuels and lubricants: $112.462 
billion. 
ÆChemicals: $103.779 billion. 
ÆMedicinal/dental/pharmaceutical 
products: $53.277 billion. 
•Gross imports plus gross exports: 
$612.949 billion. 
For estimating benefits of this topic, 
according to the 2012 CFS, commodities worth $13,852,143 million were transported in the U.S. in 2012, of which $2,334,425 million worth were hazardous (or 16.9 percent).
12However, 
the 16.9 percent proportion (of total shipment values classed as hazardous materials) estimated may have had a high-side bias due to the variety of different classes of products classified as hazardous. The percentage of shipments properly classified as hazardous is likely lower, particularly for medicinal/dental/pharmaceuticals (for this analysis PHSMA assume 10 percent). 
Multiplying this $613 billion 
(rounded) figure by 10 percent (the estimated proportion of annual trade in these three industries that are hazardous products) by the average hazard communication cost per dollar of hazardous materials produced in the United States ($0.001) results in an estimate of benefits of $61.2 million (rounded) annually. Over the ten-year analysis period from 2019 to 2028, this equates to a net present value of $431 million to $522 million, using a 7 
percent and 3 percent discount rate, respectively. 
Because it is difficult to directly 
compare the scope and nature of changes made in the OSHA rule with those made by PHMSA in each HM–215 rulemaking series, the estimates developed should be considered illustrative of very rough and highly uncertain impacts of general harmonization, Given the high degree of uncertainty in these estimates, due to the inability of PHMSA to align provisions in this rule, and their potential impacts, with the OSHA rule we use to draw our estimate from, we do not consider these quantified cost savings, averted costs, or benefits. PHMSA requests comments on the general harmonization benefit methodology utilized as well as any qualitative or quantitative information that our stakeholders can provide on the impact of general harmonization to their operations. 
Corrosivity Classification: Current 
regulations require shippers to classify Class 8 materials to a packing group based on animal test data or to utilize authorized in vitro test methods. However, these regulations require that data obtained from the testing qualify as the only acceptable data for the classification and assignment to a packing group. The proposed addition of § 173.137(d) provides alternative packing group assignment methods to classify corrosive mixtures that does not 
involve physical testing. The proposed tiered approach to classification and packing group assignment depends on how much information is available for the mixture itself, similar mixtures, and/ or its ingredients. Specifically, the proposed amendments include the following methods of classification for mixtures: Dilution, batching, criteria for substantially similar mixtures, and a calculation method using existing data for the component substances of the mixture. 
PHMSA expects there to be cost 
savings to shippers of mixtures that chose to classify their materials using the new classification options instead of traditional testing methods (e.g. in-vitro 
or in-vivo). Traditional skin corrosion testing involving animals costs approximately $1,800. Whereas, the alternative in-vitro tests range from $500 to $850,
13 14with a median cost of $675.

membrane barrier for $500. 
15Occupation labor rates based on 2017 
Occupational and Employment Statistics Survey (OES) for ‘‘Chemical Engineers (17–2041)’’ in the Chemical Manufacturing industry. The hourly mean wage for this occupation ($54) is adjusted to reflect the total costs of employee compensation based on the BLS Employer Costs for Employee Compensation Summary, which indicates that wages for civilian workers are 68.3 percent of total compensation (total wage = wage rate/wage % of total compensation). The new classification methods for 
mixtures are faster and demonstrate an equivalent level of safety at a much lower cost. PHSMA expects that many shippers of Class 8 materials will use the new regulatory flexibility to utilize the lower cost, non-testing alternatives. 
These non-test methods have varying 
degrees of time required for determination of a classification. Methods such as dilution and batching are relatively straight forward and require minimal time to arrive at a classification determination. Methods such as bridging and calculation require more time to arrive at a classification determination. PHMSA does not have a reliable estimate of the time to perform these non-test classification methods. For the purposes of this analysis, we have utilized the most time-consuming calculation method. To arrive at a classification determination using the calculation method the person preforming the calculation must utilize data on the known components of the mixture, and using a formula arrive at a number that correlates to an assignment of a packing group. PHMSA assumes that data on components of a mixture will generally be available, and 
that preforming this calculation takes approximately 3 hours to complete. Utilizing a weighted hourly wage of $79.06,
15PHMSA estimates a cost of 
$237.18 for preforming the calculation method to arrive at a corrosivity classification determination. The median cost of currently authorized in- vitro and in-vivo testing is $1,237.5. This represents a cost savings of $1,000.32 per test. 
PHSMA is challenged in monetizing 
total cost savings due to a lack of data describing baseline conditions, including a breakdown of the types of hazardous materials that make up the 2012 CFS total flow estimates and the total number of traditional tests industry currently conducts annually to comply with § 173.137. In addition, PHSMA does not have enough information to predict how this proposed rulemaking will change industry behavior. Absent more definitive data, PHMSA assumes 500 to 3,000 new mixtures tested per year. If all of these mixtures use the new non-testing methods, and cost savings equal $1,000.32 per test, total industry cost savings could equate to $0.4 to $3.9 million dollars per year. PHSMA seeks comment if these numbers represent an accurate estimate of new mixtures tested annually. 
Costs of Harmonization 
Please see the RIA for this 
rulemaking—a copy of which has been 
placed in the docket—for detailed analysis of the costs of various amendments proposed in this NPRM. Additionally, where noted below, please see the Paperwork Reduction Act section of this rulemaking for a detailed discussion of applicable proposals. 
Requiring 6(d) testing for certain 
explosives: PHMSA believes that 
requiring additional tests will result in greater costs for manufacturers of explosives presently approved for transport under UN0349, UN0367, UN0384, or UN0481. Please see the Paperwork Reduction Act section of this rulemaking for a detailed discussion of these estimated costs. 
Lithium Battery Test Summary: 
PHMSA believes that the proposed creation of a lithium cell or battery test summary and the proposed requirement for subsequent distributors to make the test summary available will result in costs to cell and battery manufacturers, as well as subsequent distributors. Please see the Paperwork Reduction Act section of this rulemaking for a detailed discussion of these estimated costs. 
Net Benefit 
Based on the discussions of benefits 
and costs provided above, PHMSA 
estimates discounted net cost savings at 3 percent discount rate of approximately $97,000–$2.2 million per year and at 7 percent discount rate of approximately $60,000–$2.1 million per year. Please see the complete RIA for a more detailed analysis of the costs and benefits of this proposed rule. 
C. Executive Order 13771 
This proposed rule has been analyzed 
in accordance with Executive Order 
13771 (‘‘Reducing Regulation and Controlling Regulatory Costs’’) and is likely to result in an E.O. 13771 deregulatory action, as it will result in cost savings (see above for discussion of the Benefits and Costs of Harmonization). 
D. Executive Order 13132 
This proposed rule has been analyzed 
in accordance with the principles and 
criteria contained in Executive Order 13132 (‘‘Federalism’’). It preempts State, local, and Indian tribe requirements, but does not propose any regulation that has substantial direct effects on the States, the relationship between the national government and the States, or the distribution of power and responsibilities among the various levels of government. Therefore, the consultation and funding requirements of Executive Order 13132 do not apply. 
The Federal hazmat law (49 U.S.C. 
5101 et seq.) contains an express 
preemption provision (49 U.S.C. 5125(b)) that preempts State, local, and Indian tribe requirements on certain covered subjects, as follows: 
(1) The designation, description, and 
classification of hazardous material; 
(2) The packing, repacking, handling, 
labeling, marking, and placarding of hazardous material; 
(3) The preparation, execution, and 
use of shipping documents related to hazardous material and requirements related to the number, contents, and placement of those documents; 
(4) The written notification, 
recording, and reporting of the unintentional release in transportation of hazardous material; and 
(5) The design, manufacture, 
fabrication, inspection, marking, maintenance, recondition, repair, or testing of a packaging or container represented, marked, certified, or sold as qualified for use in transporting hazardous material in commerce. 
This proposed rule addresses covered 
subject items (1), (2), (3), (4), and (5) above and preempts State, local, and Indian tribe requirements not meeting the ‘‘substantively the same’’ standard. This proposed rule is necessary to incorporate changes adopted in international standards, effective January 1, 2019. If the proposed changes are not adopted in the HMR, U.S. companies—including numerous small entities competing in foreign markets— would be at an economic disadvantage because of their need to comply with a dual system of regulations. The changes in this proposed rulemaking are intended to avoid this result. Federal hazmat law provides at 49 U.S.C. 5125(b)(2) that, if DOT issues a regulation concerning any of the covered subjects, DOT must determine and publish in the Federal Register the effective date of Federal preemption. The effective date may not be earlier than the 90th day following the date of issuance of the final rule and not later than two years after the date of issuance. PHMSA proposes that the effective date of Federal preemption be 90 days from publication of a final rule in this matter.

This proposed rule was analyzed in 
accordance with the principles and 
criteria contained in Executive Order 13175 (‘‘Consultation and Coordination with Indian Tribal Governments’’). Because this proposed rule does not have tribal implications, and does not impose substantial direct compliance costs the funding and consultation requirements of Executive Order 13175 do not apply. 
F. Regulatory Flexibility Act, Executive 
Order 13272, and DOT Procedures and Policies 
The Regulatory Flexibility Act (5 
U.S.C. 601 et seq.) requires an agency to 
review regulations to assess their impact on small entities, unless the agency determines that a rule is not expected to have a significant economic impact on a substantial number of small entities. This proposed rule facilitates the transportation of hazardous materials in international commerce by providing consistency with international standards. It applies to offerors and carriers of hazardous materials, some of whom are small entities, such as chemical manufacturers, users and suppliers, packaging manufacturers, distributors, and training companies. As previously discussed under ‘‘Executive Order 12866,’’ the amendments in this proposed rule should result in net cost savings and ease the regulatory compliance burden for shippers engaged in domestic and international commerce, including trans-border shipments within North America. 
Many companies will realize 
economic benefits as a result of these amendments. Additionally, the changes effected by this NPRM will relieve U.S. companies, including small entities competing in foreign markets, from the burden of complying with a dual system of regulations. Therefore, PHMSA expects that these amendments will not, if promulgated, have a significant economic impact on a substantial number of small entities. However, PHMSA solicits comments on the anticipated economic impacts to small entities. 
This proposed rule has been 
developed in accordance with Executive Order 13272 (‘‘Proper Consideration of Small Entities in Agency Rulemaking’’) and DOT’s procedures and policies to promote compliance with the Regulatory Flexibility Act to ensure that 
potential impacts of draft rules on small entities are properly considered. 
G. Paperwork Reduction Act 
PHMSA is proposing to revise the 
approved information collections under the following Office of Management and 
Budget (OMB) Control Numbers: OMB Control No. 2137–0018, ‘‘Inspection and Testing of Portable Tanks and Intermediate Bulk Containers;’’ OMB Control No. 2137–0034, ‘‘Hazardous Materials Shipping Papers & Emergency Response Information;’’ OMB Control No. 2137–0557, ‘‘Approvals for Hazardous Materials;’’ OMB Control No. 2137–0572, ‘‘Testing Requirements for Non-Bulk Packaging (Formerly: Testing Requirements for Packaging);’’ OMB Control No. 2137–0559, ‘‘Rail Carriers and Tank Car Tank Requirements, Rail Tank Car Tanks—Transportation of Hazardous Materials by Rail.’’ 
OMB Control Number 2137–0018, 
‘‘Inspection and Testing of Portable Tanks and Intermediate Bulk Containers’’ 
PHMSA estimates this rulemaking 
will result in an increase in burden due to the proposed requirement to indicate the water temperature during a hydraulic pressure test for rigid plastics and composite IBCs. PHMSA does not estimate an increase in the number of respondents or responses, because the proposed amendment only adds burden for respondents already pressure testing rigid plastics and composite IBCs. PHMSA estimates that it will take an average of 1 additional minute to add the additional information to the test report. This information collection, currently accounts for 20 respondents completing 100 test reports per year at 6 minutes per response. Increasing the burden time to 7 minutes per response increases the burden by 33 hours. At a mean hourly wage of $38.77,
16it is 
estimated to increase annual salary costs by $1,279.41. PHMSA does not anticipate this requirement to affect out- of-pocket expenses.

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

this occupation ($45.78) is adjusted to reflect the total costs of employee compensation (i.e., benefits)

documents utilizing these test reports with an average time to complete of 13 minutes. In these exercises, the test reports contained almost all the information required for completion of the test summary. PHMSA expects this to be the case for most test summaries and assumes that test reports will be readily available for most design types, but to account for the procuring of any missing information where required, we have estimated the test summary completion time to be 30 minutes. Therefore, PHMSA estimates that this proposal will increase burden by 2,920 hours (5,840 test reports × 30 minutes). 
To determine the projected salary cost 
for preparing new test summaries, PHMSA estimates a mean hourly wage rate of approximately $67.03
18for a 
total of $195,721.76 in salary cost (2,920 burden hours × $67.03). PHMSA does 
not estimate any out-of-pocket expenses for the creation of the test summary. 
Uncertainties 
—Information on company websites 
generally only accounts for battery 
and cells that are currently actively offered for sale by the company. The proposed TS requirement would be applicable to all batteries and cells manufactured after June 30, 2003. Thus, the canvassing of domestic manufacturer websites does not account for these previously made cells and batteries. 
—While several websites did show 
component cells for sale, others did not. It is difficult to know if some battery manufacturers that only list completed batteries on their websites also make their own cells. —Canvassing searched 14 domestic 
lithium battery cell and battery manufacturers (out of an estimated 73). Companies that did not provide individual product listings were not included in our calculations. However, the companies that were researched do constitute a representative sample of lithium cell and battery manufacturers making cells and batteries for automobiles, military, medical, and portable electronic devices.

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

PHMSA is also proposing additional 
requirements that would affect the 
burden for OMB Control No. 2137–0034, but PHMSA believes that the overall effect on the number of respondents and burden hours are negligible in relationship to the number of respondents and burden hours currently associated with this information collection. The requirements include proposing: To require ‘‘TEMPERATURE CONTROLLED’’ on a shipping paper if not already indicated in the proper shipping, when appropriate; to remove 1-dodecene to the list of marine pollutants in Appendix B to § 172.101; to reduce the information required 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 NPRM will 
increase the overall burden for this information collection request. PHMSA is proposing to add special provision 347 to four entries on the HMT, which would require the articles to pass the 6(d) test from Part I of the UN Manual of Tests and Criteria to maintain Compatibility Group ‘‘S’’ classification. It is estimated that this will increase the number of annual respondents by 54. PHMSA estimates that each respondent will submit 10 applications each year, for a total increase of 540 annual responses (54 respondents × 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 × 4.75 hours). At a mean hourly wage of $79.06,

of $202,797 in salary costs. PHMSA does not estimate any additional out-of- pocket expenses.

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

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

Under the Paperwork Reduction Act 
of 1995, no person is required to 
respond to an information collection unless it has been approved by OMB and displays a valid OMB control number. Section 1320.8(d) of title 5 of the CFR requires that PHMSA provide interested members of the public and affected agencies and opportunity to comment on information and recordkeeping requests. PHMSA specifically requests comments on the information collection and recordkeeping burdens associated with developing, implementing, and maintaining these proposed requirements. Address written comments to the Dockets Unit as identified in the 
ADDRESSES section of 
this rulemaking. We must receive comments regarding information collection burdens prior to the close of the comment period identified in the 
DATES section of this rulemaking. In 
addition, you may submit comments specifically related to the information collection burden to the PHMSA Desk Officer, Office of Management and Budget, at fax number 202–395–674. Requests for a copy of this information collection should be directed to Steven Andrews or Shelby Geller, Standards and Rulemaking Division (PHH–10), Pipeline and Hazardous Materials Safety Administration, 1200 New Jersey Avenue SE, Washington, DC 20590– 0001. If these proposed requirements are adopted in a final rule, PHMSA will submit the revised information collection and recordkeeping requirements to OMB for approval. 
H. Regulation Identifier Number (RIN) 
A regulation identifier number (RIN) 
is assigned to each regulatory action 
listed in the Unified Agenda of Federal Regulations. The Regulatory Information Service Center publishes the Unified Agenda in April and October of each year. The RIN contained in the heading of this document can be used to cross- reference this action with the Unified Agenda. 
I. Unfunded Mandates Reform Act of 
1995 
This proposed rule does not impose 
unfunded mandates under the Unfunded Mandates Reform Act of 
1995. It does not result in costs of $160.8 million or more, adjusted for inflation, to either State, local, or tribal governments, in the aggregate, or to the private sector in any one year, and is the least burdensome alternative that achieves the objective of the rule. 
J. Environmental Assessment 
The National Environmental Policy 
Act of 1969, 42 U.S.C. 4321–4375, 
requires that Federal agencies analyze proposed actions to determine whether the action will have a significant impact on the human environment. The Council on Environmental Quality (CEQ) regulations that implement NEPA (40 CFR parts 1500–1508) require Federal agencies to conduct an environmental review considering (1) the need for the proposed action, (2) alternatives to the proposed action, (3) probable environmental impacts of the proposed action and alternatives, and (4) the agencies and persons consulted during the consideration process. 
1. Purpose and Need 
This NPRM would amend the HMR 
(49 CFR parts 171–180) to maintain 
alignment with international standards by incorporating the 20th Revised Edition of the UN Model Regulations, Amendment 39–18 to the IMDG Code, the 2019–2020 ICAO Technical Instructions, and Transport Canada’s newest amendments to TDG Regulations. 
This action is necessary to incorporate 
changes adopted in the IMDG Code, the ICAO Technical Instructions, and the UN Model Regulations, effective January 1, 2019. If the changes in this proposed rule are not adopted in the HMR by this effective date, U.S. companies— including numerous small entities competing in foreign markets—would be at an economic disadvantage because of their need to comply with a dual system of regulations. The changes in this proposed rulemaking are intended to avoid this result. 
The intended effect of this action is to 
align the HMR with international transport standards and requirements to the extent practicable in accordance with Federal hazmat law (see 49 U.S.C. 5120). When considering the adoption of international standards under the HMR, PHMSA reviews and evaluates each amendment on its own merit, on its overall impact on transportation safety, and on the economic implications associated with its adoption. Our goal is to harmonize internationally without diminishing the level of safety currently provided by the HMR or imposing undue burdens on the regulated public. PHMSA has provided a brief summary of each revision and the justification for the revision. 
2. Alternatives 
In proposing this rulemaking, PHMSA 
is considering the following 
alternatives: 
No Action Alternative 
If PHMSA were to select the No 
Action Alternative, current regulations 
would remain in place and no new provisions would be added. 
Preferred Alternative 
This alternative is the current 
proposal as it appears in this NPRM, 
applying to transport of hazardous materials by various transport modes (highway, rail, vessel, and aircraft). The proposed amendments included in this alternative are more fully addressed in the preamble and regulatory text sections of this NPRM. However, they generally include: 
(1) Updated references to various 
international hazardous materials transport standards; 
(2) Amendments to the Hazardous 
Materials Table to include twelve new N.O.S. entries for articles containing dangerous goods, as well as additional defining criteria, authorized packagings, and safety requirements for transportation of these articles; 
(3) Amendments to add, revise, or 
remove certain proper shipping names, packing groups, special provisions, packaging authorizations, bulk packaging requirements, and vessel stowage requirements. Additionally, changes throughout the packaging requirements in part 173 to authorize more flexibility when choosing packages for hazardous materials; 
(4) Changes to the corrosivity 
classification procedures to include methods that do not involve testing for making a corrosivity classification determination for mixtures; 
(5) The creation of a lithium cell or 
battery test summary; and 
(6) Amendments to the HMR 
regarding the segregation of lithium cells and batteries offered for transport or transported on aircraft in relation to other hazardous materials. 
3. Probable Environmental Impact of the 
Alternatives 
No Action Alternative 
If PHMSA were to select the No 
Action Alternative, current regulations 
would remain in place and no new provisions would be added. However, efficiencies gained through harmonization with updates to international transport standards— 
VerDate Sep<11>2014 18:40 Nov 26, 2018 Jkt 247001 PO 00000 Frm 00034 Fmt 4701 Sfmt 4702 E:\FR\FM\27NOP2.SGM 27NOP2amozie on DSK3GDR082PROD with PROPOSALS261003 Federal Register / Vol. 83, No. 228 / Tuesday, November 27, 2018 / Proposed Rules 
including regulated substances, 
definitions, packagings, stowage requirements/codes, flexibilities allowed, enhanced markings, segregation requirements, etc.—would not be realized. 
Additionally, the No Action 
Alternative would not adopt enhanced and clarified regulatory requirements, which are intended to decrease the risk of environmental and safety incidents. For example, updates to corrosivity classification requirements are intended to better ensure that hazardous materials in this hazard class are properly identified. The lithium battery test summary and the lithium battery segregation requirements are intended to provide added protections against the risks that lithium batteries pose to air transportation. Also, the vessel stowage requirements seek to better separate materials that may be reactive to reduce the risks of serious incidents. While these are only a few examples, the provisions proposed in this Notice have been developed and vetted by the U.S. and international experts responsible for the following hazardous materials standards: UN Model Regulations, ICAO Technical Instructions, IMDG Code, and the Transport Canada TDG Regulations. Not adopting the proposed environmental and safety requirements in the NPRM under the No Action Alternative would result in a lost opportunity for reducing environmental and safety-related incidents. 
Greenhouse gas emissions would 
remain relatively the same under the No 
Action Alternative. However, it is expected that fewer incidents result in fewer emissions of greenhouse gases and other pollutants. 
Preferred Alternative 
If PHMSA selects the provisions as 
proposed in this NPRM, we believe that 
safety and environmental risks would be reduced and that protections to human health and environmental resources would be increased. Potential environmental impacts of each proposed amendment in the preferred alternative are discussed as follows: 
1. Incorporation by Reference: 
PHMSA proposes to update references to various international hazardous materials transport standards including the 2019–2020 ICAO Technical Instructions; Amendment 39–18 to the IMDG Code; the 20th Revised Edition of the UN Model Regulations; amendment 1 to the 6th Revised Edition of the UN Manual of Tests and Criteria; and the latest amendments to the Transport Canada TDG Regulations. Additionally, we propose to add three new references to standards and update six other references to standards applicable to the 
manufacture use and requalification of pressure vessels published by the International Organization for Standardization. 
PHMSA believes that this proposed 
amendment, which will increase standardization and consistency of regulations, will result in greater protection of human health and the environment. Consistency between U.S. and international regulations enhances the safety and environmental protection of international hazardous materials transportation through better understanding of the regulations, an increased level of industry compliance, the smooth flow of hazardous materials from their points of origin to their points of destination, and consistent emergency response procedures in the event of a hazardous materials incident. The HMR authorize shipments prepared in accordance with the ICAO Technical Instructions from transport by aircraft and for transport by motor vehicle either before or after being transported by aircraft. Similarly, the HMR authorize shipments prepared in accordance with the IMDG Code if all or part of the transportation is by vessel. The authorizations to use the ICAO Technical Instructions and the IMDG Code are subject to certain conditions and limitations outlined in part 171 subpart C. 
Harmonization will result in more 
targeted and effective training, thereby facilitating enhanced environmental protection. This proposed amendment will eliminate inconsistent hazardous materials regulations, which hamper compliance training efforts. For ease of compliance with appropriate regulations, air and vessel carriers engaged in the transportation of hazardous materials generally elect to comply with the ICAO Technical Instructions and IMDG Code, as appropriate. 
Greenhouse gas emissions would 
remain the same under this proposed 
amendment. 
2. Consistent with amendments 
adopted into the UN Model Regulations, PHMSA proposes to revise the Hazardous Materials Table in § 172.101 to include 12 new N.O.S. entries for articles containing dangerous goods and to add into the HMR defining criteria, authorized packagings, and safety requirements for transportation of these articles. Inclusion of entries in the HMT 
reflects a degree of danger associated with a particular material and identifies appropriate packaging intended to reduce the likelihood of release of hazardous materials that threaten human health and safety and the environment. This proposed change 
provides a level of protection and consistency for all articles specifically listed in the HMT, without diminishing environmental protection and safety. 
Greenhouse gas emissions would 
remain the same under this proposed amendment. 
3. PHMSA proposes amendments to 
the HMT to add, revise, or remove certain proper shipping names, packing groups, special provisions, packaging authorizations, bulk packaging requirements, and vessel stowage requirements. Amendments to HMT proper shipping names include: requiring additional 6(d) testing for certain explosive articles; adding an entry for ‘‘Lithium batteries installed in cargo transport unit’’; and adding two new entries for ‘‘Toxic solid, flammable, inorganic, n.o.s.’’ Additionally, we also 
propose to add and revise special provisions, large packaging authorizations, and intermediate bulk container (IBC) authorizations consistent with the UN Model 
Regulations to provide a wider range of packaging options to shippers of hazardous materials. 
Inclusion of entries in the HMT 
reflects a degree of danger associated with a particular material and identifies appropriate packaging. These proposed inclusions in the HMT provide a greater level of protection against release and consistency across borders. 
4. Changes to the corrosivity 
classification procedures to include methods that do not involve testing for making a corrosivity classification determination for mixtures. 
PHMSA believes that this proposed 
amendment permits additional flexibility for classifying corrosive mixtures and allows offerors the ability to make a classification and packing group assignment without having to conduct physical tests. This allowance does not compromise environmental protection or safety. Increased use of not-test methods for classification of mixtures results in less product being utilized to conduct physical testing, less clean-up and disposal that occurs after testing, which provide environmental benefits along with expanded alternatives to traditional testing methods. 
5. Consistent with amendments 
adopted into the UN Model Regulations, PHMSA proposes to require the creation of a lithium cell or battery test summary. 
PHMSA believes that these proposed 
amendments provide important additional information to downstream shippers and consumers of lithium batteries, including a standardized set of

elements that provide traceability and 
accountability that lithium cells and batteries offered for transport meet the appropriate UN design tests. Testing standards for lithium batteries help ensure design types are subject to as many as eight separate tests designed to assess their ability to withstand the anticipated rigors incurred during transport. Increased availability of documentation indicating that cells and batteries are of a tested type could lead to a decrease in the number of illegitimate lithium batteries that can present a hazard to users and the environment. 
6. Amendments to the HMR regarding 
the segregation of lithium cells and batteries offered for transport or transported on aircraft in relation to other hazardous materials. 
PHMSA believes that the proposed 
amendments requiring lithium batteries to be segregated from other listed dangerous goods would enhance safety and environmental protection by decreasing the risk posed by a fire involving lithium batteries or another dangerous good. The segregation requirements are intended to avoid the cumulative effects of a fire involving both goods simultaneously. PHMSA believes that this proposed amendment would provide for a net increase in environmental protection and safety by potentially lessening the severity of a fire aboard an aircraft, thus preventing release and damage to human health and the natural environment. 
Summary 
In summary, consistency between 
these international regulations and the 
HMR allows shippers and carriers to train their hazmat employees in a single set of requirements for classification, packaging, hazard communication, handling, stowage, etc., thereby minimizing the possibility of improperly preparing and transporting a shipment of hazardous materials because of differences between domestic and international regulations. These proposed changes mirror changes in the Dangerous Goods List of the 20th Revised Edition of the UN Model Regulations, the 2019–2020 ICAO Technical Instructions, and Amendment 39–18 to the IMDG Code. It is extremely important for the domestic HMR to mirror these international standards regarding the entries in the HMT to ensure consistent naming conventions across modes and international borders. 
In some instances, the proposed 
changes in this Notice may result in a streamlining or reduction in burden to industry. However, in each case, PHMSA believes that those changes are consistent with safety and will not 
significantly increase the risk of release. Most of the proposed regulations in this Notice increase protections aimed at avoiding safety and environmental risks. 
Greenhouse gas emissions would not 
significantly increase under this proposed amendment, but fewer incidents are expected to result in fewer emissions of greenhouse gases and other pollutants. 
4. Agencies Consulted 
This NPRM represents PHMSA’s first 
action in the U.S. for this program area. 
PHMSA has coordinated with the U.S. Federal Aviation Administration, the Federal Motor Carrier Safety Administration, the Federal Railroad Administration, and the U.S. Coast Guard, in the development of this proposed rule. PHMSA will consider the views expressed in comments to the NPRM submitted by members of the public, state and local governments, and industry. 
5. Conclusion 
The provisions of this proposed rule 
build on current regulatory 
requirements in order to enhance the transportation safety and security of shipments of hazardous materials transported by highway, rail, aircraft, and vessel, thereby reducing the risks of an accidental or intentional release of hazardous materials and consequent environmental damage. PHMSA proposes to find that the net environmental impact of this proposal will be positive and that there are no significant environmental impacts associated with this proposed rule. PHMSA welcomes any views, data, or 
information related to environmental impacts that may result if the proposed requirements are adopted, as well as the ‘‘no action alternative’’ and other viable alternatives and their environmental impacts. 
K. Privacy Act 
Anyone is able to search the 
electronic form of any written 
communications and comments received into any of our dockets by the name of the individual submitting the document (or signing the document, if submitted on behalf of an association, business, labor union, etc.). You may review DOT’s complete Privacy Act Statement in the Federal Register published on April 11, 2000 (65 FR 19477), or you may visit http://www.dot.gov/privacy.html. L. Executive Order 13609 and 
International Trade Analysis 
Under Executive Order 13609 
(‘‘Promoting International Regulatory Cooperation’’), agencies must consider whether the impacts associated with significant variations between domestic and international regulatory approaches are unnecessary or may impair the ability of American business to export and compete internationally. In meeting shared challenges involving health, safety, labor, security, environmental, and other issues, international regulatory cooperation can identify approaches that are at least as protective as those that are or would be adopted in the absence of such cooperation. International regulatory cooperation can also reduce, eliminate, or prevent unnecessary differences in regulatory requirements. 
Similarly, the Trade Agreements Act 
of 1979 (Pub. L. 96–39), as amended by the Uruguay Round Agreements Act (Pub. L. 103–465), prohibits Federal agencies from establishing any standards or engaging in related activities that create unnecessary obstacles to the foreign commerce of the United States. For purposes of these requirements, Federal agencies may participate in the establishment of international standards, so long as the standards have a legitimate domestic objective, such as providing for safety, and do not operate to exclude imports that meet this objective. The statute also requires consideration of international standards and, where appropriate, that they be the basis for U.S. standards. 
PHMSA participates in the 
establishment of international standards to protect the safety of the American public, and it has assessed the effects of the proposed rule to ensure that it does not cause unnecessary obstacles to foreign trade. In fact, the rule is designed to facilitate international trade. Accordingly, this rulemaking is consistent with Executive Order 13609 and PHMSA’s obligations under the Trade Agreement Act, as amended. 
M. National Technology Transfer and 
Advancement Act 
The National Technology Transfer 
and Advancement Act of 1995 (15 U.S.C. 272 note) directs Federal agencies to use voluntary consensus standards in their regulatory activities unless doing so would be inconsistent with applicable law or otherwise impractical. Voluntary consensus standards are technical standards (e.g., specification of materials, test methods, or performance requirements) that are developed or adopted by voluntary

involves multiple voluntary consensus standards which are discussed at length in the discussion on § 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 °C (68 °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 × 10
¥10cm3/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 of this subchapter. 
e. When transported by highway, rail, 
vessel, or as cargo on an aircraft, neutron radiation detectors containing not more than 1 gram of boron trifluoride, including those with solder glass joints are not subject to any other requirements of this subchapter provided they meet the requirements in paragraph a of this special provision and are packed in accordance with paragraph b of this special provision. Radiation detection systems containing such detectors are not subject to any other requirements of this subchapter provided they are packed in accordance with paragraph c of this special provision. 
* * * * * 
369 In accordance with § 173.2a of 
this subchapter, this radioactive 
material in an excepted package possessing toxic and corrosive properties is classified in Division 6.1 with radioactivity and corrosive subsidiary risks. * * * 
* * * * * 
387 When materials are stabilized by 
temperature control, the provisions of 
§ 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 °C (122 °F). If chemical stabilization becomes ineffective at lower temperatures within the anticipated duration of transport, temperature control is required and is forbidden by aircraft. In making this determination factors to be taken into consideration include, but are not limited to, the capacity and geometry of the packaging and the effect of any insulation present, the temperature of the material when offered for transport, the duration of the journey, and the ambient temperature conditions typically encountered in the journey (considering also the season of year), the effectiveness and other properties of the stabilizer employed, applicable operational controls imposed by regulation (e.g. requirements to protect 
from sources of heat, including other cargo carried at a temperature above ambient) and any other relevant factors. The provisions of this special provision will be effective until January 2, 2021, unless we terminate them earlier or extend them beyond that date by notice of a final rule in the Federal Register. 
388 a. Lithium batteries containing 
both primary lithium metal cells and rechargeable lithium ion cells that are not designed to be externally charged, must meet the following conditions: 
i. The rechargeable lithium ion cells 
can only be charged from the primary lithium metal cells; 
ii. Overcharge of the rechargeable 
lithium ion cells is precluded by design; 
iii. The battery has been tested as a 
primary lithium battery; and

Manual of Tests and Criteria, part III, subsection 38.3 (IBR, see § 171.7 of this subchapter). 
b. Lithium batteries conforming to 
paragraph a. of this special provision must be assigned to UN Nos. 3090 or 3091, as appropriate. When such batteries are transported in accordance with § 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. 
389 This entry only applies to 
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. The lithium batteries must meet the requirements of § 173.185(a) and contain the necessary systems to prevent overcharge and over discharge between the batteries. 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 incident to transport. 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. Hazardous materials not necessary for the safe and proper operation of the cargo transport unit must not be transported within the cargo transport unit. The batteries inside the cargo transport unit are not subject to marking or labelling requirements of part 172 subparts D and E of this subchapter. The cargo transport unit shall display the UN number in a manner in accordance with § 172.332 of this subchapter and be placarded on two opposing sides. For transportation by aircraft, cargo transport units may only be offered for transportation and transported under conditions approved by the Associate Administrator. 
391 Except for articles being 
transported by motor vehicle as a 
material of trade in accordance with § 173.6 of this subchapter, articles containing hazardous materials of Division 2.3, or Division 4.2, or Division 4.3, or Division 5.1, or 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: (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, may only be offered for transportation and transported under conditions approved by the Associate Administrator.

A liquid, or a solid which may become liquid during transportation, that has a severe corrosion rate on steel or aluminum based on the criteria in § 173.137(c)(2) is also a corrosive material. Whenever practical, in vitro test methods authorized in § 173.137 of this part or historical data authorized in paragraph (c) of this section should be used to determine whether a material is corrosive. 
* * * * * 
■22. Section 173.137 is revised to read 
as follows: § 173.137 Class 8—Assignment of packing 
group. 
The packing group of a Class 8 
material is indicated in Column 5 of the 
§ 172.101 Table. When the § 172.101 Table provides more than one packing group for a Class 8 material, the packing group must be determined using data obtained from tests conducted in 
accordance with the OECD Guidelines for the Testing of Chemicals, Number 435, ‘‘In Vitro Membrane Barrier Test 
Method for Skin Corrosion’’ (IBR, see § 171.7 of this subchapter) or Number 404, ‘‘Acute Dermal Irritation/ Corrosion’’ (IBR, see § 171.7 of this 
subchapter). A material that is determined not to be corrosive in accordance with OECD Guideline for the Testing of Chemicals, Number 430, ‘‘In Vitro Skin Corrosion: 
Transcutaneous Electrical Resistance Test (TER)’’ (IBR, see § 171.7 of this 
subchapter) or Number 431, ‘‘In Vitro Skin Corrosion: Reconstructed Human Epidermis (RHE) Test Method’’ (IBR, see § 171.7 of this subchapter) may be considered not to be corrosive to human skin for the purposes of this subchapter without further testing. However, a material determined to be corrosive in accordance with Number 430 or Number 431 must be further tested using Number 435 or Number 404. The packing group assignment using data obtained from tests conducted in accordance with OECD Guideline Number 404 or Number 435 must be as follows: 
(a) Packing Group I. Materials that 
cause irreversible damage to intact skin tissue within an observation period of up to 60 minutes, starting after the exposure time of three minutes or less. 
(b) Packing Group II. Materials, other 
than those meeting Packing Group I, criteria that cause irreversible damage to intact skin tissue within an observation period of up to 14 days, starting after the exposure time of more than three minutes but not more than 60 minutes.

(c) Packing Group III. Materials, other 
than those meeting Packing Group I or 
II criteria— 
(1) That cause irreversible damage to 
intact skin tissue within an observation period of up to 14 days, starting after the 
exposure time of more than 60 minutes but not more than 4 hours; or 
(2) That do not cause irreversible 
damage to intact skin tissue but exhibit a corrosion on either steel or aluminum surfaces exceeding 6.25 mm (0.25 inch) a year at a test temperature of 55 °C 
(130 °F) when tested on both materials. 
The corrosion may be determined in accordance with the UN Manual of Tests and Criteria (IBR, see § 171.7 of this subchapter) or other equivalent test methods. 
(d) Alternative packing group 
assignment methods for mixtures. For mixtures it is necessary to obtain or derive information that allows the criteria to be applied to the mixture for the purpose of classification and assignment of packing groups. The approach to classification and assignment of packing groups is tiered, and is dependent upon the amount of information available for the mixture itself, for similar mixtures and/or for its ingredients. The flow chart in Figure 1 to paragraph (d) outlines the process to be followed: 
(1) Bridging principles. Where a 
mixture has not been tested to 
determine its skin corrosion potential, but there is sufficient data on both the individual ingredients and similar tested mixtures to adequately classify and assign a packing group for the mixture, this data will be used in accordance with the following bridging principles. This ensures that the classification process uses the available data to the greatest extent possible in characterizing the hazards of the mixture. 
(i) Dilution. If a tested mixture is 
diluted with a diluent which does not meet the criteria for Class 8 and does not affect the packing group of other ingredients, then the new diluted mixture may be assigned to the same packing group as the original tested mixture. In certain cases, diluting a mixture or substance may lead to an increase in the corrosive properties. If this is the case, this bridging principle cannot be used. 
(ii) Batching. The skin corrosion 
potential of a tested production batch of a mixture can be assumed to be substantially equivalent to that of another untested production batch of the same commercial product when produced by or under the control of the same manufacturer, unless there is reason to believe there is significant variation such that the skin corrosion potential of the untested batch has changed. If the latter occurs, a new classification is necessary. 
(iii) Concentration of mixtures of 
packing group I. If a tested mixture meeting the criteria for inclusion in packing group I is concentrated, the more concentrated untested mixture may be assigned to packing group I without additional testing. 
(iv) Interpolation within one packing 
group. For three mixtures (A, B and C) 
with identical ingredients, where mixtures A and B have been tested and are in the same skin corrosion packing group, and where untested mixture C has the same Class 8 ingredients as mixtures A and B but has concentrations of Class 8 ingredients intermediate to the concentrations in mixtures A and B, then mixture C is assumed to be in the same skin corrosion packing group as A and B. 
(v) Substantially similar mixtures. 
Given the following: 
(A) Two mixtures: (A+B) and (C+B); (B) The concentration of ingredient B 
is the same in both mixtures; 
(C) The concentration of ingredient A 
in mixture (A+B) equals the concentration of ingredient C in mixture (C+B); 
(D) Data on skin corrosion for 
ingredients A and C are available and substantially equivalent, i.e. they are the 
same skin corrosion packing group and do not affect the skin corrosion potential of B. 
(E) If the above mixture (A+B) or 
(C+B) is already classified based on test data, then the other mixture may be assigned to the same packing group. 
(2) Calculation method based on the 
classification of the substances. (i) Where a mixture has not been tested to determine its skin corrosion potential, nor is sufficient data available on similar mixtures, the corrosive properties of the substances in the mixture shall be considered to classify and assign a packing group. Applying the calculation method is only allowed if there are no synergistic effects that make the mixture more corrosive than the sum of its substances. This restriction applies only if packing group

II or III would be assigned to the 
mixture. 
(A) All Class 8 ingredients present at 
a concentration of ≥1% shall be taken into account, or <1% if these ingredients are still relevant for classifying the mixture to be corrosive to skin. 
(B) When a specific concentration 
limit (SCL) is assigned to a substance following its entry in the Hazardous Materials Table or in a special provision, this limit shall be used instead of the generic concentration limits (GCL). This appears where 1% is used in the first step for the assessment of the packing group I substances, and where 5% is used for the other steps respectively in Appendix I of this part. 
(C) The following formula must be 
used for each step of the calculation process. The criterion for a packing group is fulfilled when the result of the calculation is ≥1. The generic concentration limits to be used for the evaluation in each step of the calculation method are those found in Appendix I of this part. Where applicable, the generic concentration limit shall be substituted by the specific concentration limit assigned to the substance(s) (SCLi), and the adapted formula is a weighted average of the different concentration limits assigned to the different substances in the mixture: 
PG xi = concentration of substance 1, 2 . . . 
i in the mixture, assigned to packing 
group x (I, II or III) 
GCL = generic concentration limit SCLi = specific concentration limit assigned 
to substance i 
Note to § 173.137: When an initial test on 
either a steel or aluminum surface indicates the material being tested is corrosive, the follow up test on the other surface is not required.

(i) Data available to the person 
offering the material for transportation 
must indicate that the sample would pose a level of hazard no greater than that of a self-reactive material Type B and that the control temperature, if any, is sufficiently low to prevent any dangerous decomposition and sufficiently high to prevent any dangerous phase separation; 
(ii) The sample must be packaged in 
accordance with packing method OP2; 
(iii) Packages of the self-reactive 
material may be offered for transportation and transported in a quantity not to exceed 10 kg (22 pounds) per transport vehicle; and 
(iv) One of the following shipping 
descriptions must be assigned: 
(A) Self-reactive, liquid, type C, 4.1, 
UN 3223. 
(B) Self-reactive, solid, type C, 4.1,

(4) Samples of energetic materials for 
testing purposes. Samples of organic substances carrying functional groups listed in tables A6.1 and/or A6.2 in Annex 6 (Screening Procedures) of the UN Manual of Tests and Criteria (IBR, see § 171.7 of this subchapter) may be transported under UN 3224 or UN 3223, as applicable, of Division 4.1 provided that: 
(i) The samples do not contain any: 
(A) Known explosives; (B) Substances showing explosive 
effects in testing; 
(C) Compounds designed with the 
view of producing a practical explosive 
or pyrotechnic effect; 
(D) Components consisting of 
synthetic precursors of intentional explosives; (ii) For mixtures, complexes or salts of 
inorganic oxidizing substances of Division 5.1 with organic material(s), the concentration of the inorganic oxidizing substance is: 
(A) Less than 15%, by mass, if 
assigned to packing group I or II; or 
(B) Less than 30%, by mass, if 
assigned to packing group III; 
(iii) Available data does not allow a 
more precise classification; 
(iv) The sample is not packed together 
with other goods; 
(v) Must be packaged as follows: 
(A) The quantity per individual inner 
cavity does not exceed 0.01 g for solids 
or 0.01 mL for liquids and the maximum net quantity per outer packaging does not exceed 20 g for solids or 20 mL for liquids, or in the case of mixed packing the sum of grams and mL does not exceed 20: 
(1) The samples are carried in 
microtiter plates or multi-titer plates made of plastics, glass, porcelain or stoneware as an inner packaging; 
(2) only combination packaging with 
outer packaging comprising boxes (4A, 4B, 4N, 4C1, 4C2, 4D, 4F, 4G, 4H1 and 4H2) are permitted; or 
(B) The maximum content of each 
inner packaging does not exceed 1 g for solids or 1 mL for liquids and the maximum net quantity per outer packaging does not exceed 56 g for solids or 56 mL for liquids, or in the case of mixed packing the sum of grams and mL does not exceed 56: 
(1) The individual substance is 
contained in an inner packaging of glass or plastics of maximum capacity of 30 mL placed in an expandable polyethylene foam matrix of at least 130 mm thickness having a density of 18 ±1 g/L; (2) Within the foam carrier, inner 
packagings are segregated from each other by a minimum distance of 40 mm and from the wall of the outer packaging by a minimum distance of 70 mm. The package may contain up to two layers of such foam matrices, each carrying up to twenty-eight inner packagings; 
(3) The outer packaging consists only 
of corrugated fibreboard boxes (4G) having minimum dimensions of 60 cm (length) by 40.5 cm (width) by 30 cm (height) and minimum wall thickness of 1.3 cm. 
(vi) When dry ice or liquid nitrogen 
is optionally used as a coolant for quality control measures, all applicable requirements of this subchapter must be met. Interior supports must be provided to secure the inner packagings in the original position after the ice or dry ice has dissipated. If ice is used, the outside packaging or overpack must be leakproof. If dry ice is used, the requirements in § 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. 
■27. In § 173.225, the table following 
paragraph (c)(8), the heading of the table following paragraph (d)(4), paragraph (e), paragraph (g) introductory text, and the heading to the table in paragraph (g) are revised to read as follows:

■28. Section 173.232 is added to 
subpart E to read as follows: 
§ 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 § 172.101 Table, see UN3363, Dangerous goods in machinery or apparatus, as prescribed in § 172.102(c)(1), Special provision 136, and § 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 § 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 § 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 § 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 § 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 §§ 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. 
■29. In § 173.301b paragraphs (c)(1) 
and (d)(1) are revised to read as follow:
