I. Executive Summary

    PHMSA has initiated a rulemaking project 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 Hazardous Materials Regulations (HMR; 49 CFR parts 171 to 180) with 
international regulations and standards.
    Federal law and policy strongly favor the harmonization of domestic 
and international standards for hazardous materials transportation. The 
Federal hazardous materials transportation law (Federal hazmat law; 49 
U.S.C. 5101 et seq.) permits PHMSA to depart from international 
standards to promote safety or other overriding public interest, but 
otherwise requires PHMSA to align the HMR with international transport 
standards and requirements to the extent practicable (see 49 U.S.C. 
5120).
    Harmonization facilitates international trade by minimizing the 
costs and other burdens of complying with multiple or inconsistent 
safety requirements for transportation of hazardous materials to and 
from the United States and becomes increasingly important as the volume 
of hazardous materials transported in international commerce grows. By 
facilitating compliance, harmonization also tends to enhance safety for 
international movements, but only if the international standards 
themselves provide an appropriate level of safety. To that end, PHMSA 
actively participates in the development of international standards for 
the transportation of hazardous materials, frequently advocating the 
adoption in international standards of particular HMR requirements.
    When considering the adoption of international standards under the 
HMR, we review and consider each amendment on its own merit, on the 
basis of its overall impact on transportation safety, and the economic 
implications associated with its adoption into the HMR. Our goal is to 
harmonize without diminishing the level of safety currently provided by 
the HMR and without imposing undue burdens on the regulated community.
    This NPRM proposes to amend the HMR to maintain alignment with 
various international standards. The following are some of the more 
noteworthy proposals in this NPRM:
     Incorporate Revised Standards: PHMSA proposes to 
incorporate by reference the newest versions of various international 
hazardous materials standards including the 2013-2014 International 
Civil Aviation Organization Technical Instructions for the Safe 
Transport of Dangerous Goods by Air (ICAO Technical Instructions), 
Amendment 36-12 to the International Maritime Dangerous Goods Code 
(IMDG Code), and the 17th Revised Edition of

[[Page 49169]]

the United Nations Recommendations on the Transport of Dangerous Goods 
(UN Model Regulations). Additionally, we are proposing to update our 
incorporation by reference of the Canadian Transportation of Dangerous 
Goods Regulations to include Amendment 8 (SOR/2011-239) issued November 
9, 2011, Amendment 9 (SOR/2011-60) issued March 16, 2011, and Amendment 
10 (SOR/2011-210) issued October 12, 2011. Finally, in this NPRM PHMSA 
is proposing the adoption of updated International Standards 
Organization (ISO) standards.
    If the amendments in this proposed rule are not adopted in the HMR 
by January 1, 2013, the date most of the international standards above 
take effect, U.S. companies, including numerous small entities 
competing in foreign markets, would be at an economic disadvantage. 
These companies would be forced to comply with a dual system of 
regulations. The amendments proposed in this rulemaking are intended to 
avoid this result.
     Expand Packaging Authorizations: Consistent with 
amendments adopted by the UN Model Regulations, PHMSA proposes to adopt 
changes throughout the Part 173 packaging requirements to authorize 
more flexibility when choosing packages for hazardous materials. These 
changes include, but are not limited to, the authorization to allow 
wood as a material of package construction for certain explosives the 
authorization to use metals other than steel or aluminum for drums and 
boxes; and the authorization, where appropriate, to permit the use of 
non-removable head drums in those instances where removable head drums 
are otherwise authorized.
    These amendments will allow additional flexibility to the regulated 
community with respect to the material of construction authorized for 
such packages and types of packages authorized, without compromising 
safety.
     Revise Vessel Stowage Codes: PHMSA proposes to revise, 
consolidate, and delete various vessel stowage codes. Specifically, 
PHMSA is proposing to revise the vessel stowage location requirements 
for explosives by reducing the number of explosive stowage categories 
from 15 to 5 in column 10A of the Hazardous Materials Table (HMT) found 
in Sec.  172.101. In addition to the changes in column 10A, in this 
NPRM PHMSA is proposing modifications to the vessel stowage codes 
listed in column 10B of the HMT. These changes are designed to 
harmonize with the IMDG Code, reduce the number of redundant vessel 
stowage codes and add various vessel segregation definitions in Sec.  
176.2.
    These revisions to the vessel stowage requirements in column 10 of 
the HMT are proposed to eliminate redundant codes, align with 
modifications to the IMDG Code and to simplify the vessel stowage 
requirements by limiting the number of stowage options without 
compromising safety. PHMSA believes these changes will greatly simplify 
vessel stowage requirements and facilitate international transportation 
of hazardous materials in commerce by aligning the HMR with the IMDG 
Code, while continuing to achieve an appropriate level of safety.
     Adopt Flexible Bulk Container Requirements: PHMSA proposes 
to incorporate a new packaging definition, operational controls, 
performance-oriented standards, and testing requirements for Flexible 
Bulk Containers (FBCs). FBCs are bulk packages with a capacity over the 
currently authorized maximum volumetric capacity for IBCs. The maximum 
proposed volumetric capacity of FBCs is 15 cubic meters. PHMSA proposes 
to harmonize with the internationally recognized definition of FBCs, 
adopt performance-oriented packaging design and testing standards for 
FBCs, and impose operational controls on the use of FBCs in transport. 
These FBC requirements will be modeled after the FBC requirements 
adopted into the 17th Revised Edition of the UN Model Regulations.
    FBCs provide shippers the opportunity to utilize a reusable 
packaging for bulk shipments of certain authorized low-hazard 
commodities. The associated design-type testing requirements ensure a 
high level of packaging integrity, and experience with such packagings 
in international transportation has verified the safety of these 
packagings.
     Adopt Chemical Under Pressure Provisions: We are proposing 
to revise the HMT to include entries for chemical under pressure as 
well as incorporate other safety requirements including but not limited 
to packaging requirements, segregation requirements, quantity 
limitations, and filling limits into the HMR.
    There is often confusion with regard to the proper classification 
of chemical under pressure. Currently, these types of products are 
often incorrectly classified and transported as liquefied gases or 
shipped under special permits. The addition of packaging requirements 
specific to chemical under pressure will ensure that an appropriate 
level of safety is achieved for these unique materials.
     Specify Minimum Size Requirements for Identification 
Number Markings on Non-Bulk Packages: PHMSA proposes to add specific 
size requirements for identification number (i.e., ``UN,'' ``NA,'' 
``ID'') markings as prescribed in Sec.  172.301 for non-bulk packages. 
PHMSA proposes this minimum size marking for the ``UN,'' ``NA,'' and 
``ID'' markings to align with newly adopted requirements in the 17th 
Revised Edition of the UN Model Regulations.
    PHMSA recognizes the importance of establishing a minimum size 
requirement for the internationally recognized ``UN'' identification 
number marking system. Without a minimum size requirement for hazard 
communication, shippers may mark packages in a format that makes it 
difficult for first responders to identify the commodity associated 
with a particular package.
     Revise HMT Entries: In this NPRM, PHMSA proposes 
amendments to the Sec.  172.101 Hazardous Materials Table (HMT) to add, 
revise, or remove certain proper shipping names, hazard classes, 
packing groups, special provisions, packaging authorizations, bulk 
packaging requirements, passenger and cargo aircraft maximum quantity 
limits. The proposed changes to the HMT mirror recent changes in the 
Dangerous Goods list of The 17th Revised Edition of the UN Model 
Regulations, the IMDG Code, and the ICAO Technical Instructions.
    If adopted in a final rule, the amendments proposed in this NPRM 
will result in minimal burdens on the regulated community. The benefits 
resulting from the adoption of the amendments include enhanced 
transportation safety resulting from the consistency of domestic and 
international hazard communication and continued access to foreign 
markets by U.S. manufacturers of hazardous materials. The majority of 
amendments in this NPRM should result in cost savings and ease the 
regulatory compliance burden for shippers engaged in domestic and 
international commerce, including trans-border shipments within North 
America.
    PHMSA solicits comments on the need for these amendments and others 
proposed in this NPRM. Specifically, PHMSA requests comments on the 
benefits and costs of international harmonization, including the impact 
on safety and any other relevant concerns regarding the amendments 
proposed in this NPRM. In addition, PHMSA solicits comment from the 
regulated community

[[Page 49170]]

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 justify the aggregate costs 
as a result of the amendments proposed in this NPRM. Nonetheless, PHMSA 
solicits public comment on specific changes (for example, greater 
flexibility with regard to a particular amendment) that might improve 
the rule.

II. Background

    In a final rule published December 21, 1990 (Docket HM-181; 55 FR 
52402), the Research and Special Programs Administration (RSPA), the 
predecessor agency to PHMSA, comprehensively revised the HMR to 
harmonize U.S. hazardous materials transportation requirements with the 
UN Model Regulations. The UN Model Regulations constitute a set of 
recommendations issued by the UNSCOE and 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 nine 
additional international harmonization rulemakings under Dockets: HM-
215A [59 FR 67390]; HM-215B [62 FR 24690]; HM-215C [64 FR 10742]; HM-
215D [66 FR 33316]; HM-215E [68 FR 44992]; HM-215G [69 FR 76044]; HM-
215I [71 FR 78595]; HM-215J [74 FR 2200]; and HM-215K [76 FR 3308]. 
These rulemakings were based on biennial updates of the UN Model 
Regulations, the IMDG Code, and the ICAO Technical Instructions.
    Federal law and policy strongly favor the harmonization of domestic 
and international standards for hazardous materials transportation. The 
Federal hazardous materials transportation law (Federal hazmat law; 49 
U.S.C. 5101 et seq.) directs PHMSA to participate in relevant 
international standard-setting bodies and encourages alignment of the 
HMR with international transport standards to the extent practicable 
while recognizing that deviations may at times be necessary to be 
consistent with the public interest (see 49 U.S.C. 5120). Harmonization 
facilitates international trade by minimizing the costs and other 
burdens of complying with multiple or inconsistent safety requirements 
for transportation of hazardous materials. Harmonization has also 
become increasingly important as the volume of hazardous materials 
transported in international commerce grows. By facilitating 
compliance, harmonization enhances safety. PHMSA actively participates 
in relevant international standard-setting bodies and promotes the 
adoption of standards consistent with the high safety standards set by 
the HMR.
    When considering alignment of the HMR with international standards, 
we review and evaluate each amendment on its own merit, on the basis of 
its overall impact on transportation safety, and the on the basis of 
the economic implications associated with its adoption into the HMR. 
Our goal is to harmonize without diminishing the level of safety 
currently provided by the HMR or imposing undue burdens on the 
regulated community.
    Based on this review and evaluation, in this NPRM PHMSA is 
proposing to revise the HMR to incorporate changes from the 17th 
Revised Edition of the UN Model Regulations, Amendment 36-12 to the 
IMDG Code, and the 2013-2014 ICAO Technical Instructions, which become 
effective January 1, 2013 (The IMDG Code is effective January 1, 2013; 
however, the previous amendment may continue to be used until January 
1, 2014).
    In addition, PHMSA proposes to incorporate by reference (see 171.8) 
the newest editions of various international standards. These standards 
incorporated by reference are authorized for use, under specific 
circumstances, in Subpart C of Part 171 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, 2013.

Possible Interim Final Rule

    If the changes in this proposed rule are not adopted by January 1, 
2013, U.S. companies, including numerous small entities competing in 
foreign markets, would be at an economic disadvantage because these 
companies would be forced to comply with a dual system of regulations 
(specifically, the U.S. HMR, UN Model Regulations, and ICAO Technical 
Instructions). As previously noted, the changes to the international 
standards will take effect on January 1, 2013. Therefore, it is 
essential that a final rule incorporating these standards by reference 
be published no later than December 31, 2012 with an effective date of 
January 1, 2013. To this end, if it appears a final rule under this 
docket will not be published prior to January 1, 2013, PHMSA will 
publish a bridging document in the form of an interim final rule to 
amend the HMR by incorporating the 17th Revised Edition of the UN 
Recommendations and the 2013-2014 ICAO Technical Instructions.
    With regard to Amendment 36-12 of the IMDG Code, the International 
Maritime Organization approved an implementation date of January 1, 
2014. The current edition of the IMDG Code (Amendment 35-10) remains in 
effect through 2013 and, therefore, the newest version of the IMDG Code 
will not be included in any bridging document. The proposed 
incorporation by reference of the newest edition of the IMDG Code and 
all other changes proposed in this NPRM would be addressed in a 
subsequent final rule also under this Docket, PHMSA-2012-0027 (HM-
215L). Accordingly, any interim final rule will only incorporate by 
reference editions of the international standards that become effective 
on January 1, 2013.

III. Harmonization Proposals in this NPRM

    In addition to various revisions of the HMT and special provisions, 
in this NPRM, PHMSA is proposing the following amendments to harmonize 
the HMR with the most recent revisions to the UN Model Regulations, 
ICAO Technical Instructions, and the IMDG Code:

Chemical under pressure

    Manufacturers in the United Kingdom, the United States, Australia, 
Canada, and other countries are supplying pressurized products 
contained and transported in gas cylinders. These products are liquids 
or solids such as adhesives, coatings, and cleaners combined with a gas 
or gas mixture in pressure receptacles under sufficient pressure to 
expel the contents. These mixtures are typically expelled from the 
pressurized cylinders as foams, streams, or thick sprays.
    Currently the HMR does not address liquids or solids transported 
under pressure. A typical product that would meet this description is a 
combination of a propellant (gas phase) and a liquid or solid 
component. Accordingly, the term liquefied gas does not correctly 
identify the contents of the container, nor can the material accurately 
be described by the name of the gas or liquid/solid component alone.
    The new entries (UN numbers) and corresponding provisions for 
``chemical under pressure'' address their unique characteristics and 
ensure the safe transport of such materials. These entries and 
corresponding requirements were adopted into the 17th Revised Edition 
of the UN Model Regulations. Subsequently, ICAO and IMO adopted

[[Page 49171]]

the entries for chemicals under pressure as well as modal-specific 
requirements.
    In this NPRM, PHMSA is proposing to revise the HMT to include 
individual entries for chemical under pressure and incorporate other 
safety requirements including, but not limited to, quantity and filling 
limits and packaging and segregation requirements.

Hazardous Materials Table (HMT)

    In this NPRM, 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, and passenger and cargo aircraft maximum quantity limits. 
In addition, PHMSA is proposing to comprehensively revise vessel 
stowage requirements to align with recent changes adopted into the IMDG 
Code.

Incorporation by Reference

    In this NPRM, PHMSA proposes to incorporate by reference the latest 
editions of various international transport standards including the 
2013-2014 ICAO Technical Instructions, Amendment 36-12 of the IMDG 
Code, and the 17th Revised Edition of the UN Model Regulations. 
Additionally, we are proposing to update our incorporation by reference 
of the Canadian Transportation of Dangerous Goods Regulations to 
include Amendment 8 (SOR/2011-239) dated November 9, 2011; Amendment 9 
(SOR/2011-60) dated March 16, 2011; and Amendment 10 (SOR/2011-210) 
dated October 12, 2011. This incorporation by reference augments the 
broad reciprocity provided in Sec.  171.12 where the HMR allow the use 
of the Canadian TDG Regulations under certain conditions when 
transporting hazardous materials to or from Canada by highway or rail. 
Finally, PHMSA is proposing the incorporation by reference of new and 
updated International Standards Organization (ISO) standards.

Flexible Bulk Containers (FBCs)

    In this NPRM, PHMSA proposes to incorporate a new packaging 
definition, operational controls, performance-oriented standards, and 
testing requirements for Flexible Bulk Containers (FBCs). FBCs are 
flexible bulk packages with a capacity over the currently authorized 
maximum volumetric capacity for flexible IBCs, but not exceeding 15 
cubic meters. FBCs provide shippers the opportunity to utilize a 
reusable flexible packaging for bulk shipments of certain low-hazard 
commodities, all of which are currently authorized in non-specification 
bulk bins.
    The 17th Revised Edition of the UN Model Regulations adopted a 
performance-oriented standard for flexible bulk container design and 
testing. PHMSA proposes to harmonize with the internationally 
recognized definition of FBCs, adopt the same performance-oriented 
packaging design and testing standards for FBCs, and impose similar 
operational controls on the use of FBCs in transport. The applicable 
proposed definitions, operational controls, performance-oriented 
standards, and testing requirements will be discussed in further detail 
in the section by section review portion of this NPRM.

Explosive Definitions

    In this NPRM, PHMSA proposes modifying the definitions for 
``Articles, explosive, extremely insensitive (Articles, EEI)'' and 
``Cartridges, blank.'' We also propose to replace the definition for 
``Explosive, extremely insensitive detonating substances (EIDS)'' with 
a new definition for ``Explosive, extremely insensitive substances 
(EIS).'' Finally, we propose to add a definition for ``Auxiliary 
explosive component, isolated.'' The addition and modification of these 
definitions will provide consistency with international regulations and 
clarity when utilizing the UN test series 7 for explosive 
classification.

Packaging Authorizations

    Part 173 of the HMR describes the general requirements for 
shipments and packagings of hazardous materials. Consistent with 
amendments adopted by the UN Model Regulations, PHMSA proposes to amend 
various Part 173 packaging requirements to authorize more flexibility 
when selecting packagings for hazardous materials. These proposed 
amendments include, but are not limited to, the authorization to use 
wood as a material of package construction for certain explosives, the 
authorization to use metals other than steel or aluminum for boxes and 
drums for certain hazardous materials, and the incorporation of 
authorizations and specifications for FBCs.

Vessel Stowage Requirements

    The requirements for vessel stowage are described and specified in 
Sec.  172.101(k) and HMT entries are assigned appropriate vessel 
stowage codes and stowage special provisions in column (10) of the HMT. 
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.
    In this NPRM, we are proposing to clarify these instructions by 
revising the vessel stowage location requirements for explosives and 
reducing the number of explosive stowage categories from 15 to 5 in 
column (10A) of the HMT. Specifically, explosive stowage categories 6 
through 15 will be eliminated, and stowage categories 1 through 5 will 
be retained and modified. This consolidation of codes is proposed to 
eliminate redundant codes, align with modifications to the IMDG Code, 
and simplify the vessel stowage requirements by limiting the number of 
stowage options without compromising safety.
    In addition to the HMT changes related to explosives stowage, in 
this NPRM PHMSA is proposing modifications to the vessel stowage 
provisions listed in column (10B) of the HMT. For harmonization with 
the IMDG Code, PHMSA proposes to incorporate the addition of a new 
definition for protected from sources of heat and potential or possible 
sources of ignition (see Section 176.2 of this NPRM for definitions), 
and subsequently revise and delete various vessel stowage provisions. 
These changes were developed to eliminate redundant codes, align with 
revisions to the IMDG Code, and simplify the vessel stowage 
requirements. By limiting the number of stowage options, we believe it 
will substantially reduce the complexity of the regulations without 
compromising safety.
    The revisions and consolidations of vessel storage codes in column 
(10A) and the stowage provisions in (10B) of the HMT are discussed in 
further detail below. PHMSA believes these changes will greatly 
simplify vessel stowage requirements and facilitate the seamless 
international transport of hazardous materials by aligning with the 
IMDG Code.

Mercury

    Consistent with the various international standards, PHMSA is 
proposing to add an internationally recognized proper shipping name and 
identification number for UN3506, Mercury contained in manufactured 
articles, and the addition of a Division 6.1 (toxic) subsidiary hazard 
risk to UN2809, Mercury. Data presented to the UN Committee of Experts 
on the Transport of Dangerous Goods (UNSCOE) in the last biennium 
indicated the need for assigning a subsidiary risk of Division 6.1 to

[[Page 49172]]

UN2809, Mercury, and the need to adopt a separate description for 
UN3506, Mercury contained in manufactured articles.

IV. Amendments Not Being Considered for Adoption in This NPRM

    This NPRM proposes changes to the HMR based on amendments adopted 
in the 17th Revised Edition of the UN Model Regulations, the 2013-2014 
edition of the ICAO Technical Instructions, and Amendment 36-12 to the 
IMDG Code. We are not, however, proposing to adopt all the amendments 
made to the various international standards into the HMR.
    In many cases, amendments to the international recommendations and 
regulations have not been adopted 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. If 
we have inadvertently omitted an amendment in this NPRM, we will 
attempt to include the omission in the final rule. However, our ability 
to make changes in a final rule is limited by requirements of the 
Administrative Procedure Act (5 U.S.C. 553). In some instances, we can 
adopt a provision inadvertently omitted in the NPRM if it is clearly 
within the scope of changes proposed in the notice. Otherwise, in order 
to provide opportunity for notice and comment, the change must first be 
proposed in an NPRM.
    One of the goals of this rulemaking is to continue to maintain 
consistency between the HMR and the 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.
    The following is a list of significant amendments to the 
international regulations that we are not proposing to adopt in this 
NPRM, with a brief explanation of why the amendment was not included:

Security Provisions for High Consequence Dangerous Goods

    The 17th Revised Edition of the UN Model Regulations adopted 
modifications to the security provisions specified in Chapter 1.4 with 
regard to ``high consequence dangerous goods.'' Specifically, these 
changes address the handling of certain Class 7 radioactive materials. 
In the 17th Revised Edition the UN adopted a list of transport security 
thresholds for specific radionuclides in Table 1.4.2 of Chapter 1.4. 
Materials identified in this table exceeding the transport security 
thresholds indicated in terabecquerels (TBq) would be subject to 
additional security requirements such as security training and security 
plans.
    In this NPRM, PHMSA is not proposing the adoption of the changes to 
the security requirements found in the HMR with regard to high 
consequence dangerous goods. These amendments to the international 
recommendations and regulations are not being adopted because the 
existing safety and security requirements found in Subpart I of Part 
172 are consistent with and provide for a level of safety and security 
equivalent to the revised UN Model Regulations.

Requirements for Lithium Batteries

    On January 11, 2010, PHMSA published an NPRM in the Federal 
Register under Docket HM-224F (75 FR 1302). The NPRM included 
provisions to ensure lithium batteries are properly packaged to reduce 
the possibility of damage that could lead to a catastrophic incident, 
and minimize the consequences of an incident should one occur. In 
addition, PHMSA proposed to require lithium battery shipments to be 
accompanied by hazard communication that ensures appropriate and 
careful handling by air carrier personnel, including the flight crew, 
and informs both transport workers and emergency response personnel of 
actions to be taken in an emergency.
    Subsequently, on April 11, 2012, PHMSA published a notice in the 
Federal Register requesting additional comment on the impacts of 
changes to the requirements for the air transport of lithium cells and 
batteries that were adopted into the 2013-2014 ICAO Technical 
Instructions. PHMSA is considering whether to harmonize the HMR with 
these requirements, and published a notice to allow interested persons 
an opportunity to supplement comments to the HM-224F NPRM.
    The HM-224F NPRM and the April 11, 2012 notice, which PHMSA 
developed in close coordination with the Federal Aviation 
Administration (FAA), are the latest in a series of actions PHMSA has 
taken to address the potential risks posed by lithium batteries in 
transportation. These publications solicit comments on revisions to the 
HMR and are based on lithium battery provisions in the 16th Revised 
Edition of the UN Model Regulations and the 2013-2014 ICAO Technical 
Instructions. Because lithium batteries are addressed in separate 
battery-specific rulemakings and notices, PHMSA is not proposing 
amendments pertaining to the transportation of lithium cells and 
batteries in this NPRM. The docket for the lithium battery rulemaking 
can be found at http://www.regulations.gov under PHMSA-2009-0095.

Notification to the Pilot-In-Command

    Section 175.33 of the HMR addresses the requirements for 
notification of pilot-in-command regarding hazardous materials stowed 
aboard the aircraft. Recent amendments adopted in the upcoming 2013-
2014 edition of the ICAO Technical Instructions modify the information 
required to be given to the pilot-in-command as prescribed in Part 7; 
4.1. These modifications include a requirement that the operator of an 
aircraft transporting hazardous materials provide personnel with 
responsibilities for operational control of the aircraft with the same 
information that is required to be provided to the pilot-in-command. In 
addition, the modifications also include a table of hazardous materials 
not required to appear on the notification provided to the pilot-in-
command. Because better analysis is necessary to assess the regulatory 
impact of alignment with the ICAO Technical Instructions on this 
matter, PHMSA is not proposing to adopt the new provisions in this 
NPRM. However, PHMSA does intend to address these changes in a future 
rulemaking.

Requirements for Salvage Pressure Receptacles

    The 17th Revised Edition of the UN Model Regulations adopted 
guidelines for Competent Authorities to use when issuing approvals for 
salvage pressure receptacles. These revisions are found in Chapter 1.2, 
4.1, 5.4, and 6.2 of the UN Model Regulations. Specifically, these 
requirements address the packaging, hazard communication, and safe 
transport of salvage pressure receptacles, also known as salvage 
cylinders in the United States.
    The HMR currently address the packaging, hazard communication, and 
safe transport of salvage cylinders in Sec.  173.3(d) and do not 
require approval of the Associate Administrator to do so. PHMSA 
believes the current salvage cylinder requirements in the HMR provide a 
sufficient level of safety and adequately address the shipment of 
damaged and defective cylinders. Therefore, PHMSA is not proposing 
changes to the current HMR provisions for salvage cylinders in this 
NPRM.

Fireworks Classification Reference

    The 17th Revised Edition of the UN Model Regulations adopted 
requirements for fireworks classification references. Specifically, a 
provision was

[[Page 49173]]

adopted requiring fireworks under identification numbers UN0333, 
UN0334, UN0335, UN0336, and UN0337, having been approved by a competent 
authority, to bear a classification reference on the shipping paper. 
The classification reference would indicate the country of the 
competent authority approval and would also include a unique serial 
reference for the specific firework device.
    PHMSA intends to address fireworks-related issues in a separate 
rulemaking and, therefore, will not address fireworks-related issues in 
this NPRM. The docket for the fireworks rulemaking can be found at 
http://www.regulations.gov under PHMSA-2010-0320 (HM-257).

Criteria for Exclusion From Class 1

    The ICAO and IMO recently adopted guidance issued to competent 
authorities regarding when an article or substance can be excluded from 
meeting the classification of a Class 1 (explosive) material. PHMSA is 
not adopting the issued guidance in this NPRM because it is 
classification parameters to be considered by a competent authority and 
not actual regulatory provisions.

Air Bag Inflator, Air Bag Module, or Seat-Belt Pretensioner Revisions

    The 17th Revised Edition of the UN Model Regulations revised the 
authorized packagings used for the transportation of air bag inflators, 
air bag modules, or seat-belt pretensioners. Specifically, in addition 
to currently authorized packagings, the UN Model Regulations adopted 
authorizations for 1N2 and 1D drums, 3B2 jerricans, and 4A, 4B, 4N, and 
4H1 boxes.
    PHMSA is not addressing the additional packaging authorizations in 
this rulemaking as these and other related issues were addressed in a 
separate NPRM. The docket for the air bag inflator, air bag module, and 
seat-belt pretensioner rulemaking can be found at http://www.regulations.gov under PHMSA-2010-0201.

Pressure Relief Valves for Closed Cryogenic Receptacles

    A new provision was added to Packing Instruction P203 of the 17th 
Revised Edition of the UN Model Regulations. The amendment prescribes 
that the frequency of periodic inspection and test of the pressure 
relief valves for closed cryogenic receptacles shall not exceed five 
years.
    In this NPRM, PHMSA is not proposing to adopt this amendment. 
Section 173.316, ``Cryogenic Liquids in Cylinders,'' and Sec.  173.301, 
``General Requirements for Shipment of Compressed Gases and Other 
Hazardous Materials in Cylinders, UN Pressure Receptacles and Spherical 
Pressure Vessels'' do not specify the frequency of tests of pressure 
relief device systems. The HMR requires testing of these systems in 
accordance with the Compressed Gas Association's S-1.1, ``Pressure 
Relief Device Standards--Part 1--Cylinders for Compressed Gases'' and 
S-7, ``Method for Selecting Pressure Relief Devices for Compressed Gas 
Mixtures in Cylinders.'' PHMSA believes these requirements already 
provide for an adequate level of safety of pressure relief device 
systems.

Absorbent Materials for Air Packaging

    Numerous packing instructions of the ICAO Technical Instructions 
were revised to consistently provide that for certain liquid hazardous 
materials, inner packagings must be packed with sufficient absorbent 
material to absorb the entire contents of the inner packagings.
    PHMSA does not intend to adopt these amendments in this NPRM. 
Rather, we adopted them in a separate rulemaking under docket PHMSA-
2007-29364 (HM-231A). For example, in the final rule published in the 
Federal Register on April 16, 2012 (77 FR 22504), we revised Sec.  
173.27(e) to require that inner packagings be packaged in a rigid 
leakproof liner or rigid intermediate packaging containing sufficient 
absorbent material to absorb the entire contents of the inner packaging 
before being placed in its outer package when absorbent material was 
required. Generally, this requirement is applicable to Packing Group I 
liquids.

UN Test Series 6(d) for Certain Division 1.4S Articles

    Special provision 364 was added to the 17th Revised Edition of the 
UN Model Regulations that requires limited quantity packages of certain 
Division 1.4S explosives under the following descriptions ``UN 0012 
Cartridges for weapons, inert projectile or Cartridges, small arms,'' 
``UN0014 Cartridges for weapons, blank or Cartridges, small arms, blank 
or Cartridges for tools, blank,'' and ``UN0055 Cases, cartridge, empty 
with primer'' be capable of passing Test Series 6(d) in accordance with 
the UN Manual of Tests and Criteria as determined by the competent 
authority.
    PHMSA believes that the current requirements for shipments of these 
articles adequately address the hazards associated with the transport 
of these limited quantity hazardous materials and, thus, will not be 
adopting the requirement for these materials as packaged to be capable 
of passing Test Series 6(d) of Part I of the UN Manual of Tests and 
Criteria.

Coolants, Conditioners, and Asphyxiates

    In many instances cargo transport units are treated with substances 
to cool and condition the transport environment inside the transport 
unit. Occasionally gases presenting a risk of asphyxiation are used as 
part of this cooling and conditioning process. In this case an 
accumulation of these gases may present a risk to those handling these 
cargo transport units in transport.
    The 17th Revised Edition of the UN Model Regulations adopted 
various requirements applicable to packages and cargo transport units 
containing substances presenting a risk of asphyxiation when used for 
cooling or conditioning purposes. Requirements adopted internationally 
include a new marking requirement for both packages and freight 
containers containing dangerous goods used for cooling and conditioning 
as well as the requirement to note that a dangerous good is being used 
as a coolant or conditioner on transport documents. PHMSA believes that 
the current requirements for shipments of dry ice and other potential 
coolants adequately address the hazards associated with the use of 
these hazardous materials as coolants or conditioners and notes that 
the current provisions of the HMR would not preclude the use of the new 
marking for domestic or international transport.

V. Section-By-Section Review

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

Part 171

Section 171.7

    The ``National Technology Transfer and Advancement Act of 1996'' 
directs agencies to use voluntary consensus standards. 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

[[Page 49174]]

and safety, and protects the environment.
    To these ends, PHMSA actively participates in the development and 
updating of consensus standards through representation on more than 20 
consensus standard bodies. PHMSA regularly reviews updated consensus 
standards and considers their merit for inclusion in the HMR.
    Section 171.7 provides a listing of all standards incorporated by 
reference into the HMR. For this rulemaking, we 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 and determined that the revised standards provide an 
enhanced level of safety without imposing significant compliance 
burdens. These standards have a well-established and documented safety 
history; their adoption will maintain the high safety standard 
currently achieved under the HMR. Therefore, we propose to update by 
adding and revising the incorporation by reference materials under the 
following organizations:
    The International Civil Aviation Organization (ICAO) Technical 
Instructions for the Safe Transport of Dangerous Goods by Air, 2011-
2012 Edition is revised to incorporate the 2013-2014 Edition.
    The International Convention for the Safety of Life at Sea (SOLAS) 
Amendments 2002, Chapter II-2/Regulation 19, Consolidated Edition 2004 
is revised to incorporate the 2009 Consolidated Edition.
    The International Maritime Organization (IMO) International 
Maritime Dangerous Goods Code, 2010 Edition, Incorporating Amendment 
35-10, English Edition, Volumes 1 and 2 is revised to incorporate the 
2012 Edition, Amendment 36-12.
    The International Organization for Standardization (ISO) entries 
for ``ISO 10156:1996, Gases and Gas Mixtures--Determination of fire 
potential and oxidizing ability for the selection of cylinder valve 
outlets, Second edition, February 1996 (E)'' and ``ISO 10156-2:2005, 
Gas cylinders--Gases and gas mixtures--Part 2: Determination of 
oxidizing ability of toxic and corrosive gases and gas mixtures, First 
edition, August 2005, (E)'' are removed and replaced with entry for 
``ISO 10156:2010: Gases and gas mixtures--Determination of fire 
potential and oxidizing ability for the selection of cylinder valve 
outlets, Third edition, March 2010.''
    The entry ``ISO 4126-1: Safety valves--Part 1: General 
requirements, December 15, 1991, First edition'' is revised as the 
entry ``ISO 4126-1: Safety valves--Part 1: General requirements/Cor 1, 
August 2, 2007, Second edition.'' The entry ``ISO 11117, Gas 
cylinders--Valve protection caps and valve guards for industrial and 
medical gas cylinders--Design, construction and tests, First edition, 
August 1998, (E)'' is revised as the entry ``ISO 11117:2008/Cor 1:2009 
Gas cylinders--Valve protection caps and valve guards--Design, 
construction and tests, May 5, 2009, Second edition''.
    The entries ``ISO 4126-7: Safety valves--Part 7: Common data/Cor 1, 
October 23, 2006, First edition,'' and ``ISO 13340 Transportable gas 
cylinders--Cylinders valves for non-refillable cylinders--Specification 
and prototype testing, April 5, 2001, First edition'' are added.
    The Transport Canada entry, Transportation of Dangerous Goods 
Regulations, including Clear Language Amendments 1 through 7 is revised 
to include Amendments 8, 9 and 10.
    The United Nations Recommendations on the Transport of Dangerous 
Goods--Model Regulations, 16th Revised Edition (2009), Volumes I and 
II, is revised to incorporate the 17th Revised Edition (2011), Volumes 
I and II.
    The United Nations Recommendations on the Transport of Dangerous 
Goods--Manual of Tests and Criteria, Fifth Revised Edition (2009), is 
revised to incorporate Amendment 1 (2011).

Section 171.8

    This section defines terms generally used throughout the HMR that 
have broad or multi-modal applicability. PHMSA is proposing to add the 
following defined term based on its adoption in the 17th Revised 
Edition of the UN Model Regulations: Flexible Bulk Container (FBC): 
This term means a flexible container with a capacity not exceeding 15 
cubic meters and includes liners and attached handling devices and 
service equipment.
    Currently the HMR do not prescribe requirements for the transport 
of FBCs. In this NPRM, PHMSA is proposing to adopt various 
transportation and manufacturing requirements for FBCs. Prior to 
adoption of such standards, the term ``Flexible Bulk Container'' must 
be defined. Therefore in this NPRM we are proposing to adopt the above 
definition of an FBC based on the definition for FBC adopted in the 
IMDG Code and 17th Revised Edition of the UN Model Regulations.

Part 172

Section 172.101

    Section 172.101 provides instructions for using the Hazardous 
Materials Table (HMT) and the HMT itself. In this NPRM, PHMSA is 
proposing to revise the instructional text that precedes the HMT.
    Paragraph (c) of Sec.  172.101 describes the information indicated 
in column 2 of the HMT. Column 2 lists the hazardous materials 
descriptions and proper shipping names of materials designated as 
hazardous materials. Paragraph (c)(10) of Sec.  172.101 prescribes how 
mixtures or solutions not identified specifically by name are 
described.
    In this NPRM, PHMSA proposes to revise Sec.  172.101(c)(10) to 
incorporate language adopted in the 17th Revised Edition of the UN 
Model Regulations that states mixtures and solutions must meet the 
definition of one or more hazard class to be classified as a hazardous 
material. This change will clarify that for a mixture or solution 
composed of one or more components that are classified as a hazardous 
material, the resulting mixture or solution must meet the definition of 
one or more hazard classes to be classified as a hazardous material.
    Paragraph (k) of Sec.  172.101 explains the purpose of column (10) 
of the HMT and prescribes the vessel stowage and segregation 
requirements for specific entries in the HMT. 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.
    In this NPRM, we are proposing to modify these instructions by 
revising the vessel stowage location requirements for explosives and 
reducing the number of explosive stowage categories from 15 to 5. 
Specifically, the explosive stowage categories 6 through 15 will be 
eliminated and stowage categories 1 through 5 will be modified. Changes 
to the explosive stowage categories are necessary because, as part of 
this NPRM, PHMSA proposes to remove magazine stowage Types ``A,'' 
``C,'' and special stowage from Part 176 with the consolidation of 
authorized explosive stowage categories. The authorized explosive 
stowage categories will be replaced with a new term of art ``Closed 
cargo transport units for Class 1 (explosives).'' Included in this 
definition are freight containers or transport vehicles that are 
structurally serviceable in accordance with

[[Page 49175]]

Sec.  176.172, portable magazines conforming to Sec.  176.137, and 
small vessel compartments (i.e., mast lockers and deck house). These 
changes will require Class 1 materials to be shipped in closed cargo 
transport units as defined above when stowed on deck.
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
UN3497 Krill meal
UN3498 Iodine monochloride, liquid

    This new HMT entry is a result of the division of the proper 
shipping name Iodine monochloride into two authorized proper shipping 
names; one for the liquid state of the commodity and another for the 
solid state. Solid shipments of Iodine monochloride remain assigned to 
UN1792.

UN3499 Capacitor, electric double layer (with an energy storage 
capacity greater than 0.3 Wh)

    This new HMT entry is intended to cover capacitors with an energy 
storage capacity greater than 0.3 Wh. Capacitors are assigned as a 
Class 9 miscellaneous hazardous material and measures required to 
prevent short circuit are provided in special provision 361.

UN3500 Chemical under pressure, n.o.s.
UN3501 Chemical under pressure, flammable, n.o.s.
UN3502 Chemical under pressure, toxic, n.o.s.
UN3503 Chemical under pressure, corrosive, n.o.s.
UN3504 Chemical under pressure, flammable, toxic, n.o.s.
UN3505 Chemical under pressure, flammable, corrosive, n.o.s.

    The ``Chemical under pressure. n.o.s.'' HMT entries are added to 
address shipments of liquids or solids (e.g., adhesives, coatings, and 
cleaners) combined with a gas or gas mixtures utilized to expel the 
contents from pressure vessels. The primary hazard class for these 
shipments is determined by the hazard presented by the propellant and 
any subsidiary risk is determined by the properties of the liquid or 
solid under pressure. Toxic gases are not permitted as propellants.

UN3506 Mercury contained in manufactured articles

    This new entry was created to separately address manufactured 
articles containing mercury. The international community provided an 
exception from regulation for instruments and articles containing not 
more than 1 kg of mercury, when transported by means other than 
aircraft. PHMSA is unable to adopt a comparable exception as the 
reportable quantity for mercury is 0.454 kg (1.00 lbs.), but does 
propose to revise the current exception authorized in Sec.  173.164(e) 
for shipments containing less than 0.454 kg (1.00 pound) to include 
transportation by vessel.
Removed HMT Entries
UN3492 Toxic by inhalation liquid, corrosive, flammable, n.o.s. with an 
inhalation toxicity lower than or equal to 200 ml/m\3\ and saturated 
vapor concentration greater than or equal to 500 LC50
UN3493 Toxic by inhalation liquid, corrosive, flammable, n.o.s. with an 
inhalation toxicity lower than or equal to 1000 ml/m\3\ and saturated 
vapor concentration greater than or equal to 10 LC50

    These entries are proposed for removal from the HMT due to their 
similarity to UN3488 and UN3489 respectfully. The sole difference 
between these entries is the order of subsidiary risks, which does not 
affect the classification and transport conditions applied to shipments 
of these substances. As a result, PHMSA proposes to remove 
identification numbers UN3492 and UN3493 to avoid confusing shippers in 
determining which identification numbers to use.
Amendments to the Column (1) Symbols
    Section 172.101(b) describes column (1) of the HMT and the 
associated symbols that may be indicated in the column. In accordance 
with Sec.  172.101(b), the symbol ``G'' identifies proper shipping 
names for which one or more technical names of the hazardous material 
must be entered in parentheses in association with the basic 
description on a shipping paper. In this NPRM, PHMSA proposes to add a 
``G'' to column (1) for ``UN1707, Thallium compounds, n.o.s.'' The 
addition of a ``G'' to this entry will provide notification of the 
technical name of this toxic material and thus aid emergency responders 
with providing an appropriate response.
Amendments to the 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. Among other requirements, in accordance with Sec.  
172.101(c)(1), proper shipping names indicated in column (2) of the HMT 
may be used in the singular or the plural form interchangeably. 
Regardless, in this NPRM, PHMSA is revising several entries in the HMT 
to remove the plural ending letter ``s'' to provide continuity with the 
internationally accepted proper shipping names. Specifically, PHMSA 
proposes to remove the letter ``s'' from: UN1107, Amyl chlorides; 
UN1111, Amyl mercaptans; UN1113, Amyl nitrites; and, UN2347, Butyl 
Mercaptans.
    Generally the physical state (solid or liquid) appears before the 
hazard characteristics (toxic, flammable, etc.) in the sequence of 
wording used in proper shipping names specified in column (2) of the 
HMT. In some instances, the hazard characteristics are indicated before 
the physical state. In this NPRM, PHMSA is proposing changes to several 
proper shipping names to indicate the physical state before the hazard 
characteristics for consistency in formatting.
    Current proper shipping names:

                                             solid, toxic, n.o.s.
------------------------------------------------------------------------

    Currently, the HMT includes the entry ``Toxic, liquids, organic, 
n.o.s., UN2810'' with the proper shipping name indicated in column (2) 
that includes a comma between the words ``toxic'' and ``liquid.'' This 
is not

[[Page 49176]]

consistent with the UN Model Regulations, the ICAO Technical 
Instructions, or the IMDG Code as there is no comma between the words 
``Toxic'' and ``liquid.'' PHMSA proposes to revise this entry by 
removing the comma for consistency with international standards and 
regulations and to provide shippers with the most appropriate shipping 
description.
    A new proper shipping name ``Cartridges for tools, blank'' is 
proposed to be assigned to identification number UN0014. This proper 
shipping name more appropriately describes industrial blank cartridges 
currently described as ``UN0323, Cartridges, power device'' or ``ORM-D 
or ORM-D-AIR, Cartridges, power device (used to project fastening 
devices).'' In this NPRM, PHMSA is proposing to remove the ``ORM-D'' 
entry for ``Cartridges, power device (used to project fastening 
devices)'' as the proper shipping name for such articles is now 
``Cartridges for tools, blank'' under identification number UN0014. 
Subsequent changes will be made to Sec.  173.63 and the Sec.  
172.102(c)(1) special provision 347 to replace any references to ``ORM-
D or ORM-D-AIR, Cartridges, power device (used to project fastening 
devices)'' with the new description ``UN0014, Cartridges for tools, 
blank (used to project fastening devices).'' Additionally, such 
articles are not subject to the UN Test Series 6(d) previously required 
under special provision 347. The description ``UN0323, Cartridges, 
power device'' will remain subject to special provision 347.
    The proper shipping name for ``UN1305, Vinyltrichlorosilane, 
stabilized'' is amended by removing the term ``stabilized'' for 
consistency with the Dangerous Goods Lists of the various international 
standards and the HMT of the HMR. The proposed proper shipping name for 
UN1305 is ``Vinyltrichlorosilane.''
    The 17th Revised Edition of the UN Model Regulations modified the 
qualifying text (text in italics) for UN Nos. 3381-3390 and UN Nos. 
3488-3491. The proposed changes to these entries' qualifying or 
modifying text in italics would change the wording from ``with an 
inhalation toxicity lower than or equal to'' to ``with an LC50 lower 
than or equal to''. The intent of this terminology change is to better 
identify the criteria used to determine the proper classification of 
these substances.
    The entry ``Formaldehyde solutions (with not less than 10% and less 
than 25% formaldehyde), see Aviation regulated liquid, n.o.s. or Other 
regulated substances, liquid, n.o.s.'' appears in column (1) of the 
HMT. PHMSA proposes to revise this entry by placing it into the correct 
column (2) of the HMT. This is an editorial revision and simply 
corrects an unintended error in the HMT.
Amendments to the Column (4) identification numbers
    Section 172.101(e) describes Column (4) of the HMT and the 
designation of the identification number to each proper shipping name. 
With the proposed addition of a separate identification number (UN3506) 
for the description ``Mercury contained in manufactured articles,'' 
PHMSA proposes to remove the description that is currently assigned to 
``UN2809, Mercury.''
Amendments to the Column (6) label(s)
    Section 172.101(g) describes Column (6) of the HMT and the labels 
required (primary and subsidiary) for specific entries in the HMT. Data 
presented to the UN Committee of Experts on the Transport of Dangerous 
Goods in this last biennium indicated a need for the addition of 
subsidiary risk of Division 6.1 (toxic) to be assigned to ``UN2809, 
Mercury'' and to the new entry ``UN3506, Mercury contained in 
manufactured articles.'' We note that for air transport, Special 
provision A192 provides relief from the labeling and documentation 
requirements of this new subsidiary risk.\1\
---------------------------------------------------------------------------

    \1\ The scientific data and background regarding the adoption of 
these modifications are presented in working papers ST/SG/AC.10/C.3/
2010/6 and ST/SG/AC.10/C.3/2010/67 entitled ``Mercury (UN2809): 
Subsidiary risk 6.1'' and ``Dimethyl disulphide (UN2381): subsidiary 
risk 6.1.'' These papers can be viewed at the following URLs: http://www.unece.org/fileadmin/DAM/trans/doc/2010/ac10c3/ST-SG-AC10-C3-2010-06e.pdf. and http://www.unece.org/fileadmin/DAM/trans/doc/2010/ac10c3/ST-SG-AC10-C3-2010-67e.pdf.
---------------------------------------------------------------------------

    In addition to the changes above, data was also presented to the UN 
Committee of Experts on the Transport of Dangerous Goods that indicated 
the need for a subsidiary risk of Division 6.1 (toxic) to be assigned 
to UN2381 Dimethyl disulfide.
    PHMSA proposes to make appropriate amendments to the HMT to account 
for these revisions to the UN Model Regulations.
Amendments to the Column (7) Special Provisions
    Section 172.101(h) describes Column (7) of the HMT and the Sec.  
172.102(c) 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 for a detailed discussion 
of the proposed additions, revisions, and deletions to the special 
provisions addressed in this NPRM.
    Several HMT entries are revised to include bulk special provision 
B120. Special provision B120 indicates that the material, when offered 
in conformance with the applicable requirements of Part 178 and general 
packaging requirements in Part 173, may be offered for transportation 
in a Flexible Bulk Container. See Section 172.102 special provisions 
for a detailed discussion of our proposed addition of special provision 
B120.
    In this NPRM, special provision B120 is proposed to be assigned to 
the following entries:

------------------------------------------------------------------------
                 Proper shipping name                        UN No.

    In this NPRM, new special provision 363 is proposed to be assigned 
to the following entries:

------------------------------------------------------------------------
                 Proper shipping name                        UN No.

    See Section 172.102 special provisions for a detailed discussion of 
our proposed addition of special provision 363.
    The entry for UN1008 Boron trifluoride is assigned new special 
provision 238. See Section 172.102 Special provisions for a detailed 
discussion of our proposed addition of special provision 238.
    With the addition of a Division 6.1 (toxic) subsidiary risk to 
``UN2381, Dimethyl disulfide,'' the portable tank codes and portable 
tank provisions are proposed to be revised as follows:

T4 is replaced by T7
TP1 is replaced by TP2, TP13, and TP39

    See Section 172.102 Special provisions for a detailed discussion of 
our proposed addition of special provision TP39.
    Review of the ``Guiding Principles for the Development of the UN 
Model Regulations (Guiding Principles)'' indicates that in some cases, 
the portable tank instructions for the transport of Division 4.3 liquid 
materials are not consistent with the Guiding Principles, and, in other 
instances, relevant portable tank special provisions were missing or 
incorrectly assigned. The following changes are proposed with deletions 
indicated by a strikethrough and additions or replacements shown in 
bold font.
[GRAPHIC] [TIFF OMITTED] TP15AU12.031

    See Section 172.102 Special provisions for a detailed discussion of 
our proposed addition of special provision TP41.
    Special provisions A100 and A103 are revised to clarify that the 
weight (mass) limitations specified are net and not gross amounts for 
secondary lithium batteries. See Section 172.102 Special provisions for 
a detailed discussion of our proposed revision of special provisions 
A100 and A103.
    Special provision A192 is added to note that regardless of the 
Division 6.1 (toxic) subsidiary risk indicated in the HMT, the toxic 
subsidiary risk label and an indication of the subsidiary risk on the 
shipping paper are not required for manufactured articles containing 
less than 0.454 kg (1.00 pound) of mercury. This special provision is 
assigned to the entry ``UN3506, Mercury contained in manufactured 
articles.''
    Special provision A200 is added to require that certain articles 
may not be transported in passenger baggage and are to be shipped as 
cargo when transported via aircraft. Under certain circumstances, the 
articles affected by this special provision may be excepted from the 
requirements of the HMR. When these articles are not subject to the 
regulations, there is the potential for them to be inappropriately 
carried aboard an aircraft. In response to this safety concern, the 
ICAO Technical Instructions were revised to clarify that when 
transported by aircraft, these articles, regardless of whether they are 
otherwise excepted from the regulations, must be transported as cargo 
and may not be carried onboard an aircraft by passengers or

[[Page 49178]]

crewmembers in carry-on baggage, checked baggage, or on their person 
unless specifically excepted by Sec.  175.10, ``Exceptions for 
Passengers, Crewmembers, and Air Operators.'' Consistent with the 
revised ICAO Technical Instructions requirement, PHMSA proposes to 
adopt the special provision restricting these items from being carried 
aboard an aircraft by passengers and crewmembers.
    This special provision is assigned to the following entries: 
``UN3166, Engines, internal combustion or Engines, fuel cell, flammable 
gas powered''; ``UN3166, Engines, internal combustion or Engines, fuel 
cell, flammable liquid powered''; ``UN3166, Vehicle, flammable gas 
powered or Vehicle, fuel cell, flammable gas powered''; ``UN3166, 
Vehicle, flammable liquid powered or Vehicle, fuel cell, flammable 
liquid powered''; ``UN0503, Air bag inflators or Air bag modules or 
Seat-belt pretensioners''; and ``UN3268, Air bag inflators or Air bag 
modules or Seat-belt pretensioners.''
    Special provision W10 is assigned to ``UN3486, Calcium hypochlorite 
mixture, dry, corrosive with more than 10% but not more than 39% 
available chlorine'' and to ``UN2208, Calcium hypochlorite mixtures, 
dry, with more than 10 percent but not more than 39 percent available 
chlorine.'' Special provision W10 indicates that, when offered for 
transportation by vessel, these entries may not be offered in Large 
Packagings. See Section 172.102 Special provisions for a detailed 
discussion of our proposed addition of special provision W10.
Amendments to the Column (9) quantity limitations
    Section 172.101(j) describes Column (9) of the HMT and the quantity 
limitations for specific entries in the HMT. Furthermore, Columns (9A) 
and (9B) specify the maximum quantities that may be offered for 
transportation in one package by passenger-carrying aircraft or 
passenger-carrying rail car (Column (9A)) or by cargo-only aircraft 
(Column (9B)). Unless otherwise indicated the quantity limitations 
shown in column (9) of the HMT are net. PHMSA proposes to remove the 
gross weight indicator in columns (9A) (if authorized previously) and 
(9B) for the following battery entries. The quantity limit for these 
entries should be based on the weight of the battery or batteries and 
not the weight of the battery or batteries plus the packaging (i.e., 
the package).

UN3028 Batteries, dry, containing potassium hydroxide solid, electric, 
storage
UN2794 Batteries, wet, filled with acid, electric storage
UN2795 Batteries, wet, filled with alkali, electric storage
UN3468 Hydrogen in a metal hydride storage system or Hydrogen in a 
metal hydride storage system contained in equipment or Hydrogen in a 
metal hydride storage system packed with equipment
UN3090 Lithium battery
UN3091 Lithium batteries packed with equipment

    PHMSA is proposing to revise column (9A) to forbid several entries 
previously authorized for shipment on passenger-carrying aircraft or 
passenger-carrying rail to harmonize with changes to the ICAO Technical 
Instructions. The following entries would now be forbidden on 
passenger-carrying aircraft or passenger-carrying rail.

UN1162 Dimethyldichlorosilane
UN1196 Ethyltrichlorosilane
UN1250 Methyltrichlorosilane
UN1298 Trimethylchlorosilane
UN1305 Vinyltrichlorosilane
UN2985 Chlorosilanes, flammable, corrosive, n.o.s.
UN3361 Chlorosilanes, toxic, corrosive, n.o.s.
UN3362 Chlorosilanes, toxic, corrosive, flammable, n.o.s.

    Quantity limits of 450 L for ``UN3334, Aviation regulated liquid, 
n.o.s.'' and 400 kg for ``UN3335, Aviation regulated solid, n.o.s.'' 
are proposed for both columns (9A) and (9B). Previously, there was no 
limit to the amount authorized to be shipped in one package. These new 
quantity limits are consistent with authorized quantity limits found in 
the ICAO Technical Instructions.
Amendments to the Column (10) Vessel Stowage Requirements
Vessel Stowage Location (10A)
    Section 172.101(k) explains the purpose of column (10) of the HMT 
and prescribes the vessel stowage and segregation requirements for 
specific entries in the HMT. 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.
    PHMSA is proposing to simplify the number of vessel stowage 
locations for shipments of Class 1 explosive materials to harmonize 
with recently adopted vessel explosive stowage categories in the IMDG 
Code. Currently, there are 15 possible stowage location codes available 
for assignment to column (10A) for explosive shipments. Recent changes 
in the IMDG Code have reduced the number of available explosive stowage 
location codes to five. This consolidation of codes was accomplished to 
reduce the complexity of the regulations without compromising safety.
    The International Maritime Organization (IMO) determined that the 
term ``magazine'' was no longer necessary and the magazine concept 
could be incorporated into a broader definition for closed cargo 
transport units for Class 1 (explosives) material. In general, a 
magazine used to store and transport explosives is equivalent to a 
closed cargo transport unit with a wooden floor. A magazine type A has 
additional wooden walls, or walls covered with wooden pallets, and is 
currently only assigned to 7 entries in the HMT. A magazine type C is 
currently defined by a minimum distance to the ship's side of 2.4 m (8 
feet). Proposed requirements to load Class 1 closed cargo transport 
units a minimum distance of 2.4 m (8 feet) from the ship's side wall 
remove the need for specific stowage category references to magazine 
stowage type C. The IMO, taking into account the properties of various 
classes and divisions of explosives, has determined that only 1.4S, 
1.4G, 1.4D, and 1.4C explosives are acceptable on passenger ships. 
PHMSA agrees. Therefore, PHMSA has removed the majority of Class 1 
stowage location codes and revised the remaining codes. The codes 
proposed for each Class 1 entry are grouped by proposed stowage code 
(01, 02, 03, 04, or 05) as follows:
Proposed Explosive Stowage Category
01--means the material may be stowed ``on deck'' in closed cargo 
transport units or ``under deck'' on a cargo vessel (up to 12 
passengers) and on a passenger vessel
02--means the material may be stowed ``on deck'' in closed cargo 
transport units or ``under deck'' on a cargo vessel (up to 12 
passengers) and ``on deck'' in closed cargo transport units or ``under 
deck'' in closed cargo transport units on a passenger vessel
03--means the material may be stowed ``on deck'' in closed cargo 
transport units or ``under deck'' on a cargo vessel (up to 12 
passengers) but the material is prohibited on a passenger vessel
04--means the material may be stowed ``on deck'' in closed cargo 
transport units or ``under deck'' in closed cargo transports on a cargo 
vessel (up to 12 passengers) but the material is prohibited on a 
passenger vessel

[[Page 49179]]

05--means the material may be stowed ``on deck'' in closed cargo 
transport units on a cargo vessel (up to 12 passengers) but the 
material is prohibited on a passenger vessel

    Taking into account the properties of various classes and divisions 
of explosives, the IMO determined new stowage category assignments as 
follows:

------------------------------------------------------------------------
                                 Stowage                       Stowage

1.2B.........................           05  1.2G...........           03
1.4B.........................           05  1.3G...........           03

1.4C.........................           02  1.1J...........           05
1.1D.........................           04  1.2J...........           05
1.2D.........................           04  1.3J...........           05
1.4D.........................           02  1.2K...........           05
1.5D.........................           03  1.3K...........           05
1.1E.........................           04  1.1L...........           05
1.2E.........................           04  1.2L...........           05
1.4E.........................           03  1.3L...........           05
1.1F.........................           05  1.6N...........           03
1.2F.........................           05  1.4S...........           01
1.3F.........................           05
------------------------------------------------------------------------

    PHMSA agrees with the assignments and, in particular, agrees that 
only 1.4S, 1.4G, 1.4D, and 1.4C explosives are acceptable on passenger 
ships.
    Column (10A) in the HMT is revised to read Stowage Category 01 for

    Vessel stowage codes (10B).
    Section 172.101(k) describes Column (10) of the HMT and the vessel 
stowage requirements for specific entries in the HMT. Furthermore, 
column (10B) [Other provisions] specifies codes for stowage 
requirements for specific hazardous materials. The meaning of each code 
in Column (10B) is set forth in Sec.  176.84 of this subchapter.
    Vessel shipments of Class 1 explosives are currently required to be 
stored away from all sources of heat including steam pipes, heating 
coils, sparks, and flame in accordance with Sec.  176.116(a). In 
addition to this general provision in Sec.  176.116, several vessel 
stowage codes in column (10B) make reference to shading or stowing away 
from heat. To harmonize with the IMDG Code, reduce the number of 
redundant vessel stowage codes, and incorporate the addition of a new 
definition for protected from sources of heat (see Section 176.2 of 
this NPRM for definition) PHMSA proposes to delete vessel stowage codes 
50 and 48 and replace all references to these codes with stowage code 
25. See Section 176.84 for a detailed discussion of our proposed 
revision to stowage code 25.
    The following proper shipping names and corresponding 
identification numbers will have stowage code 48 replaced with stowage 
code 25 in Column (10B) in the HMT.

    We also propose to assign stowage code 25 to every Class 1 
explosive table entry to indicate these materials must be protected 
from sources of heat in accordance with the new proposed definition of 
``protected from sources of heat'' in Sec.  176.2. See Section 176.84 
for a detailed discussion of our proposed revision to stowage code 25 
and Sec.  176.2 for the proposed definition of ``protected from sources 
of heat.''
    Stowage code 50 is currently not assigned to any HMT entries and is 
being proposed for deletion in this NPRM.
    PHMSA proposes to revise stowage code 128 to account for a citation 
change in the IMDG Code. The proposed new text of stowage code 128 is 
``stow in accordance with the IMDG Code, Sub-section 7.6.2.7.2 
(incorporated by reference; see Sec.  171.7 of this subchapter).''
    PHMSA proposes to delete stowage codes 7E, 8E, and 20E. The 
proposed reduction in the number of vessel stowage categories in column 
(10A) makes these codes unnecessary and any applicable stowage 
requirements are covered by the requirements of the applied code in 
column (10A). Consequently, we propose to remove stowage codes 7E, 8E, 
or 20E from the following entries, as applicable:
    The following proper shipping names and corresponding 
identification numbers will have stowage code 7E removed from column 
(10B) of the HMT.

    During review of the explosive stowage codes it was noted that 
stowage code 1E was assigned to UN0504 1H-Tetrazole and UN0502 Rockets, 
with inert head. Stowage code 1E was removed in a final rule published 
on June 21, 2001, under Docket Number RSPA-2000-7702 (HM-215D) [66 FR 
33316] entitled, ``Harmonization with the United Nations 
Recommendations, International Maritime Dangerous Goods Code, and 
International Civil Aviation Organization's Technical Instructions'' 
and, in this NPRM, PHMSA proposes to amend the listings for these two 
entries by removing these two codes whose requirements have been 
captured by other vessel stowage provisions.

Section 172.102 Special Provisions

    Section 172.102 lists special provisions applicable to the 
transportation of specific hazardous materials. Special provisions 
contain packaging requirements, prohibitions, and exceptions applicable 
to particular quantities or forms of hazardous materials. PHMSA is 
proposing the following revisions to the Sec.  172.102, Special 
provisions:
Special Provision 47
    Special provision 47 provides classification exceptions for 
mixtures of solids and flammable liquids. In this NPRM, PHMSA proposes 
to revise special provision 47 to clarify that the requirement that 
each packaging must correspond with a design type that has passed a 
leakproofness test at the Packing Group II level applies only to single 
packagings.
Special Provision 48
    Special provision 48 provides classification exceptions for 
mixtures of solids and toxic liquids. In this NPRM, PHMSA proposes to 
revise special provision 47 to clarify that the requirement that each 
packaging must correspond with a design type that has passed a 
leakproofness test at the Packing Group II level applies only to single 
packagings.
Special Provision 49
    Special provision 49 provides classification exceptions for 
mixtures of solids and corrosive liquids. In this NPRM, PHMSA proposes 
to revise special provision 49 to clarify that the requirement that 
each packaging must correspond with a design type that has passed a 
leakproofness test at the Packing Group II level applies only to single 
packagings.
Special Provision 101
    In a NPRM published in the Federal Register on August 31, 2006 (71 
FR 51895), we proposed to remove Sec.  172.102(c)(1), Special provision 
101. In the NPRM, we stated that with the introduction of the letter 
``G'' in Column (1), which requires the n.o.s. and generic proper 
shipping names to be supplemented with the technical name of the 
hazardous material, Special Provision 101 became obsolete. 
Consequently, because we did not receive public comment, the amendment 
was adopted as proposed in a final rule published in the Federal 
Register on December 29, 2006 (71 FR 78596).
    Consequences of the removal of Sec.  172.102(c)(1) Special 
provision 101 in 2006 may have resulted in

[[Page 49186]]

noncompliance for certain Department of Defense (DOD) explosive 
shipments. DOD recently asserted the current provisions in Sec. Sec.  
171.8 and 172.203(k) of the HMR do not permit technical names to be 
indicated in such a manner as former Special provision 101 required. 
For example, a DOD explosive shipment approved under the generic 
description ``Articles, explosive, n.o.s.'' was previously assigned 
Special provision 101 in column 7 of the Sec.  172.101 Hazardous 
Materials Table that required the name of the particular substance or 
article to be specified as the technical name for the substance or 
article (e.g., ``Fuze, Grenade, M219A2'') in association with the basic 
description. Therefore, in this notice, PHMSA is proposing to reinstate 
special provision 101 for the following HMT entries:
UN0349 Articles, explosive, n.o.s.
UN0350 Articles, explosive, n.o.s.
UN0351 Articles, explosive, n.o.s.
UN0352 Articles, explosive, n.o.s.
UN0353 Articles, explosive, n.o.s.
UN0354 Articles, explosive, n.o.s.
UN0355 Articles, explosive, n.o.s.
UN0356 Articles, explosive, n.o.s.
UN0462 Articles, explosive, n.o.s.
UN0463 Articles, explosive, n.o.s.
UN0464 Articles, explosive, n.o.s.
UN0465 Articles, explosive, n.o.s.
UN0466 Articles, explosive, n.o.s.
UN0467 Articles, explosive, n.o.s.
UN0468 Articles, explosive, n.o.s.
UN0469 Articles, explosive, n.o.s.
UN0470 Articles, explosive, n.o.s.
UN0471 Articles, explosive, n.o.s.
UN0472 Articles, explosive, n.o.s.
UN0382 Components, explosive train, n.o.s.
UN0383 Components, explosive train, n.o.s.
UN0384 Components, explosive train, n.o.s.
UN0461 Components, explosive train, n.o.s.
UN0357 Substances, explosive, n.o.s.
UN0358 Substances, explosive, n.o.s.
UN0359 Substances, explosive, n.o.s.
UN0473 Substances, explosive, n.o.s.
UN0474 Substances, explosive, n.o.s.
UN0475 Substances, explosive, n.o.s.
UN0476 Substances, explosive, n.o.s.
UN0477 Substances, explosive, n.o.s.
UN0478 Substances, explosive, n.o.s.
UN0479 Substances, explosive, n.o.s.
UN0480 Substances, explosive, n.o.s.
UN0481 Substances, explosive, n.o.s.
UN0485 Substances, explosive, n.o.s.
UN0482 Substances, explosive, very insensitive, n.o.s. or 
Substances, EVI, n.o.s.
Special Provision 118
    Special provision 118 states that materials listing this special 
provision may not be transported under the provisions of Division 4.1 
unless specifically authorized by the Associate Administrator. In the 
UN Model Regulations the corresponding special provision, SP 272, 
contained a note that the special provision referred to UN0143. This 
special provision in the UN Model Regulations has been revised to 
indicate that the special provision applies to both UN0143 and UN0150, 
as appropriate. To maintain consistency with the UN Model Regulations, 
in this NPRM PHMSA proposes to adopt this editorial note and revise 
special provision 118 by adding the language ``(see UN0143 or UN0150 as 
appropriate)'' following the existing text.
Special Provision 134
    Special provision 134 would be revised to note that this provision 
also applies to equipment powered by wet batteries or sodium batteries 
that are transported with these batteries installed. This is a minor 
clarification of the original intent of this special provision.
Special Provision 155
    Special provision 155 states that Fish meal or fish scrap may not 
be transported if the temperature at the time of loading either exceeds 
35 [deg]C (95[emsp14][deg]F), or exceeds 5 [deg]C (9[emsp14][deg]F) 
above the ambient temperature, whichever is higher.
    In this NPRM PHMSA proposes to revise special provision 155 by 
adding a reference to the new proper shipping name ``krill meal.'' 
Krill meal processes similar self-heating hazard characteristics to 
fish meal and scrap; therefore, application of this special provision 
is appropriate. This addition will clarify that special provision 155 
applies to fish meal and fish scrap as well as krill meal. This 
revision is a clarification of the existing requirement.
Special Provision 237
    Special provision 237 specifies that ``Batteries, dry, containing 
potassium hydroxide solid, electric storage '' must be prepared and 
packaged in accordance with the requirements of Sec.  173.159(a), (b), 
and (c) and that for transportation by aircraft, the provisions of 
Sec.  173.159(b)(2) are applicable.
    In this NPRM PHMSA is proposing to add an additional sentence to 
special provision 237 clarifying the applicability of the provision. 
Specifically language is added to state that the entry for ``Batteries, 
dry, containing potassium hydroxide solid, electric storage'' may only 
be used for the transport of non-activated batteries that contain dry 
potassium hydroxide and that are intended to be activated prior to use 
by the addition of an appropriate amount of water to the individual 
cells.
Special Provision 238
    Special provision 238 is added to address neutron radiation 
detectors. Neutron detection is a key component used in nuclear arms 
interdiction in addition to other applications such as nuclear reactor 
monitoring, neutron-based cancer treatments, neutron spallation, 
nondestructive testing and health physics applications. Most neutron 
radiation detectors contain boron trifluoride gas, UN1008, which is 
currently forbidden by passenger and cargo aircraft as noted in Columns 
(9A) and (9B) of the HMT. Currently, neutron radiation detectors that 
contain this gas can only be transported by air under the terms of a 
special permit.
    ICAO recently adopted a special provision specifically addressing 
neutron radiation detectors. The recently adopted special provision 
A191 permits, under certain conditions the transportation by cargo 
aircraft of neutron radiation detectors that contain boron trifluoride. 
These conditions include quantity of gas limitations, construction and 
packaging specifications. The special provision also provides that 
under certain conditions these neutron radiation detectors containing 
not more than 1 gram of boron trifluoride gas are not otherwise subject 
to the ICAO Technical Instructions.
    PHMSA granted a special permit, for the transportation by all 
modes, of certain neutron radiation detectors containing boron 
trifluoride gas. The limitations set forth in Special Provision A191 of 
the ICAO Technical Instructions do not exceed any limitations of the 
special permit and, therefore, PHMSA proposes to adopt and apply them 
to all modes of transportation except passenger-carrying aircraft by 
incorporating them into Sec.  172.102(c)(1), Special provision 238. 
Specifically, the special provision will provide packaging requirements 
(including pressure limitations), quantities permitted, and package 
construction requirements for radiation detectors containing non-
pressurized boron trifluoride gas in excess of 1 gram. The special 
provision also provides additional exceptions from the HMR based on the 
transport mode and other conditions. The special provision is 
applicable to the entry ``UN1008, Boron trifluoride'' in the HMT. PHMSA 
believes the adoption of this special provision provides an adequate 
level of safety for the transportation of these items, while providing 
flexibility and without the need to obtain a special permit.
Special Provision 328
    A new special provision 328 is added to clarify that when lithium 
cells or batteries are contained in the fuel cell system, the item must 
be described

[[Page 49187]]

under this entry and the entry ``Lithium batteries, contained in 
equipment.'' This special provision will be applied to UN3473 ``Fuel 
cell cartridges or Fuel cell cartridges contained in equipment or Fuel 
cell cartridges packed with equipment, containing flammable liquids''; 
UN3476 ``Fuel cell cartridges or Fuel cell cartridges contained in 
equipment or Fuel cell cartridges packed with equipment, containing 
water-reactive substances''; UN3477 ``Fuel cell cartridges or Fuel cell 
cartridges contained in equipment or Fuel cell cartridges packed with 
equipment, containing corrosive substances''; UN3478 ``Fuel cell 
cartridges or Fuel cell cartridges contained in equipment or Fuel cell 
cartridges packed with equipment, containing liquefied flammable gas''; 
and UN3479 ``Fuel cell cartridges or Fuel cell cartridges contained in 
equipment or Fuel cell cartridges packed with equipment, containing 
hydrogen in metal hydride.''
Special Provision 360
    A new Special Provision 360 would be added and assigned to UN3091, 
``Lithium batteries, contained in equipment'' to clarify that vehicles 
powered only by lithium batteries must be assigned to identification 
number UN3071, ``Battery powered vehicle''.
Special Provision 361
    A new special provision 361 is added to clarify that certain 
capacitors with limited energy storage capability are excepted from the 
HMR. Specifically, the special provision will state that capacitors 
with an energy storage capacity of 0.3 Wh or less are not subject to 
the HMR. Furthermore this special provision will define energy storage 
capacity as the energy held by a capacitor, as calculated using the 
nominal voltage and capacitance.
    Proposed Sec.  173.176 provides that capacitors not installed in 
equipment must be transported in an uncharged state and capacitors 
installed in equipment must be transported in either an uncharged state 
or protected against short circuit. Certain types of capacitors such as 
asymmetrical capacitors are designed to maintain a terminal voltage. 
This special provision will also clarify the entry UN3499 does not 
apply to these capacitors. This special provision will be applied to 
the proposed HMT entry UN3499, ``Capacitor, electric double layer (with 
an energy storage capacity greater than 0.3 Wh).''
Special Provision 362
    A new special provision 362 is added to specify when a material can 
be considered a chemical under pressure. Specifically, the special 
provision will state that classification of these materials is to be 
based on hazard characteristics of the components in the propellant, 
the liquid, or the solid forms. Further, this special provision will 
detail the appropriate primary and subsidiary hazard classes to be 
assigned to chemicals under pressure. Special provision 362 would be 
added and assigned to the following HMT entries: UN3500, Chemical under 
pressure, n.o.s.; UN3501, Chemical under pressure, flammable, n.o.s.; 
UN3503, Chemical under pressure, corrosive, n.o.s.; UN3502, Chemical 
under pressure, toxic n.o.s.; UN3504, Chemical under pressure, 
flammable, toxic, n.o.s.; and UN3505, Chemical under pressure, 
flammable, corrosive, n.o.s.
Special Provision 363
    Prior to the publication of the 17th Revised Edition of the UN 
Model Regulations, the transport of large amounts of fuel in machinery 
was not specifically addressed in international transport regulations. 
In the most recent biennium of the UNSCOE, some experts expressed 
concerns about the transport of large amounts of fuel in machinery. 
This concern lead the international community to adopt in The 17th 
Revised Edition of the UN Model Regulations a special provision 
associated with fuel-related Class 3 entries.
    Special Provision 363, as adopted in the UN Model Regulations, 
requires an article that contains fuel in excess of the limited 
quantity authorized amount and is ineligible to be described as 
Dangerous Goods in Machinery or Apparatus, UN3363, to conform to 
several general provisions to avoid being subject to the remainder of 
the HMR. Shipments utilizing this special provision require that the 
means of containment be in compliance with the construction 
requirements of the competent authority, all valves or openings in the 
means of containment containing dangerous goods shall be closed during 
transport, the machinery or equipment shall be loaded in an orientation 
to prevent leakage, and: (1) If the means of containment has a capacity 
of not more than 450 liters, one label would be required; (2) if the 
means of containment has a capacity greater than 450 liters but not 
more than 1,500 liters, it must be labeled on all four sides; or (3) if 
the means of containment has a capacity greater than 1,500 liters, it 
must be placarded on each side and each end. Additionally, shipping 
papers are required for such articles.
    In this NPRM, PHMSA proposes to adopt Special Provision 363 modeled 
on the corresponding special provision adopted in the UN Model 
Regulations. This special provision would be assigned to the following 
HMT entries for transportation by vessel: UN1202, Gas oil or Diesel 
fuel or Heating oil, light; UN1203, Gasoline including when mixed with 
ethyl alcohol, with not more than 10% alcohol; UN1223, Kerosene; 
UN1268, Petroleum distillates, n.o.s. or Petroleum products, n.o.s.; 
UN1863, Fuel, aviation, turbine engine; and UN3475, Ethanol and 
gasoline mixture or Ethanol and motor spirit mixture or Ethanol and 
petrol mixture, with more than 10% ethanol.
    While PHMSA generally agrees with the concept of addressing 
machinery or apparatus containing flammable liquid fuels in amounts 
that exceed the authorized limited quantity amounts and are ineligible 
to be described as UN3363, Dangerous goods in machinery or apparatus, 
we do have concerns related to the potential impact that adopting this 
special provision would have on shippers of generators and other 
similar articles that may currently be described as UN3166, Engines 
internal combustion, and are not subject to fuel limitations when 
transported by highway or rail. Conversely, PHMSA is soliciting public 
comment regarding any potential negative impact on the efficient and 
seamless flow of international commerce if we choose not to adopt 
Special Provision 363 in a final rule.
Special Provision 365
    With the official adoption of a new proper shipping name UN3506 
Mercury contained in manufactured articles in the 17th Revised Edition 
of the UN Model Regulations to address manufactured articles containing 
mercury, PHMSA proposes to add a new special provision 365 stating that 
manufactured instruments and articles containing mercury should 
reference UN3506. This special provision will be applied to UN2809 
Mercury.
Special Provision A60
    Special Provision A60 permits UN2014, Hydrogen peroxide, aqueous 
solution, to be transported in excepted quantities provided a 
comparative fire test between packages containing the solution and 
identical packages containing water demonstrated no difference in the 
burning rate. The likelihood of finding discernible differences with 
more accurate test equipment used today is much greater than it would 
have been with equipment used when the test

[[Page 49188]]

requirements were first developed. This more sensitive equipment often 
detects negligible differences between the two test subjects and, 
therefore, precludes transport of these small devices under the special 
provision. To address the issue, the ICAO Dangerous Goods Panel (DGP) 
adopted a proposal to allow small differences in burning rates.
    In this NPRM we are proposing to harmonize with the ICAO Technical 
Instructions with regard to the comparative fire test for Hydrogen 
peroxide, aqueous solution. Special provision A60 is revised 
accordingly.
Special Provision A100
    Special Provision A100 states that primary (non-rechargeable) 
lithium batteries and cells are forbidden for transport aboard 
passenger-carrying aircraft and secondary (rechargeable) lithium 
batteries and cells are authorized aboard passenger-carrying aircraft 
in packages that do not exceed a gross weight of 5 kg.
    In this NPRM special provision A100 is revised to clarify the 
weight limitations for secondary lithium batteries are net and not 
gross quantities. There are some combinations of authorized battery 
packagings that contribute significantly towards the gross weight of 
the finished package. The intent of this proposed change is to indicate 
that the quantity limits for secondary lithium battery shipments aboard 
passenger-carrying aircraft are to be based on the actual weight of the 
batteries in each individual package and not the weight of the 
completed package.
Special Provision A103
    Special Provision A103 specifies that lithium batteries contained 
in equipment is authorized aboard passenger carrying aircraft if the 
gross weight of the inner package of secondary lithium batteries or 
cells packed with the equipment does not exceed 5 kg (11 pounds).
    In this NPRM special provision A103 is revised to clarify the 
weight limitations are net and not gross quantities. There are some 
combinations of authorized battery packagings that contribute 
significantly towards the gross weight of the finished package. The 
intent of this proposed change is to indicate that the quantity limits 
for secondary lithium battery shipments aboard passenger carry aircraft 
are to be based on the actual weight of the batteries in each 
individual package and not the weight of the completed package.
Special Provision A189
    In this NPRM, we are proposing to add a new special provision, 
A189, which will be assigned to the HMT entry ``UN2209, Formaldehyde 
solutions, with not less than 25 percent formaldehyde'' indicating how 
Formaldehyde solutions with more than 25% are to be classified. It was 
suggested at the ICAO DGP that the entry for ``UN2209, Formaldehyde 
solution with not less than 25% formaldehyde'' implied that 
concentrations of less than 25% formaldehyde were not regulated. To 
clarify these requirements, the ICAO DGP adopted a new special 
provision detailing how differing percentage of formaldehyde solutions 
are regulated.
    In this NPRM, we are proposing to add language detailing how 
differing percentage of Formaldehyde solutions are to be regulated in 
the new special provision A189. This special provision will be applied 
to UN3334, Aviation regulated liquid, n.o.s. and NA3082, Other 
regulated substances, liquid, n.o.s.
Special Provision A192
    A new special provision, A192, is added noting that regardless of 
the Division 6.1 subsidiary hazard indicated in the HMT, the poison 
subsidiary risk label and an indication of this subsidiary risk on the 
shipping paper are not required for manufactured articles containing 
less than 0.45 kg (1 pound) of mercury. This provision aligns with the 
decision of the UN Sub-Committee to ensure that transport of such 
articles, particularly by air, is not impeded due to mercury's revised 
classification.
Special Provision A200
    As previously discussed, a new special provision, A200, is added 
stating the entries assigned this special provision must be transported 
as cargo when transported by aircraft and cannot be carried onboard an 
aircraft by passengers or crewmembers either in or as carry-on baggage, 
checked baggage, or on their person unless specifically excepted by 
Sec.  175.10, ``Exceptions for Passengers, Crewmembers, and Air 
Operators.'' This special provision would be assigned to articles and 
will be applied to: UN3166, Engines, internal combustion or Engines, 
fuel cell, flammable gas powered; UN3166, Engines, internal combustion, 
or Engines, fuel cell, flammable liquid powered; UN3166, Vehicle, 
flammable gas powered or Vehicle, fuel cell, flammable gas powered; 
UN3166, Vehicle, flammable liquid powered or Vehicle, fuel cell, 
flammable liquid powered; UN0503, Air bag inflators, or Air bag 
modules, or Seat-belt pretensioners; and, UN3268, Air bag inflators, or 
Air bag modules, or Seat-belt pretensioners.
Special Provision B120
    A new special provision B120 is added to specify the use of FBCs 
conforming to the requirements in Subpart R and Subpart S of part 178 
of this subchapter are permitted. The special provision is applicable 
to the following entries:

------------------------------------------------------------------------
                     Proper shipping name                        UN No.
------------------------------------------------------------------------
Ammonium nitrate based fertilizer............................     UN2067
Ammonium nitrate, with not more than 0.2% total combustible       UN1942
 material, including any organic substance, calculated as
 carbon to the exclusion of any other added substance........
Calcium nitrate..............................................     UN1454
Environmentally hazardous substance, solid, n.o.s............     UN3077
Magnesium nitrate............................................     UN1474
Naphthalene, crude or Naphthalene, refined...................     UN1334
Paraformaldehyde.............................................     UN2213
Potassium nitrate............................................     UN1486
Sodium carbonate peroxyhydrate...............................     UN3378
Sodium nitrate...............................................     UN1498
Sodium nitrate and potassium nitrate mixtures................     UN1499
Sodium perborate monohydrate.................................     UN3377
Sulfur (domestic and international entries)..................     UN1350
------------------------------------------------------------------------

    FBCs must conform to the performance-oriented construction 
standards and testing criteria in new subparts R and S of part 178. In 
addition, shipments of FBCs must be prepared and otherwise conform to 
the general requirements for bulk packages in subpart B of part 173 and 
the proposed new Sec.  173.37.
IBC Codes
    In a final rule published in the Federal Register on January 19, 
2011 (76 FR 3308; HM-215K), the Table 1 (IBC Codes) in paragraph (c)(4) 
were editorially revised to remove UN Specifications 31A, 31B and 31N 
from IBC Codes IB4 through IB8. The revision was consistent with 
amendments to international standards that removed the specifications 
from the indicated codes in the table because IBC Codes IB4 through IB8 
are assigned to solids, whereas, UN Specifications 31A, 31B, and 31N 
are authorized for transportation of liquids in IBC Codes IB1 through 
IB3 and are assigned to liquid materials only. In the January 19, 2011 
final rule, PHMSA inadvertently failed to also remove the remaining

[[Page 49189]]

liquid IBC specifications (31H1, 31H2, 31HZ1, and 31HZ2) from IB Codes 
IB4 through IB8. Therefore, in this NPRM, PHMSA is editorially 
correcting the IBC Code Table in Sec.  172.102(c)(4).
Special Provision TP39
    A new special provision, TP39, is added and assigned to HMT 
entry``UN2381, Dimethyl disulfide.'' This special provision indicates 
that portable tank instruction T4 may continue to be applied until 
December 31, 2018. This will provide more time for portable tank 
transporters to transition their current fleets.
Special Provision TP40
    A new special provision TP40 is added and assigned to HMT entries 
``UN3500, Chemical under pressure, n.o.s.; UN3501, Chemical under 
pressure, flammable, n.o.s.; UN3503, Chemical under pressure, 
corrosive, n.o.s., UN3503; UN3502, Chemical under pressure, toxic 
n.o.s.; UN3504, Chemical under pressure, flammable, toxic, n.o.s.; and 
UN3505, Chemical under pressure, flammable, corrosive, n.o.s.'' The 
special provision indicates that the portable tanks must not be 
transported when connected with spray application equipment. This will 
provide an additional measure preventing inadvertent release of 
hazardous materials in transport.
Special Provision TP41
    A new Special provision TP41 is added and assigned to HMT entries 
``UN3148, Water-reactive liquid, n.o.s.,'' indicating that the portable 
tank instruction T9 may continue to be applied until December 31, 2018.
Special Provision TP50
    Special provision T50 is revised to note that this provision is 
applicable to chemicals under pressure as well as liquefied compressed 
gases. Special provision T50 would be assigned to HMT entries ``UN3500, 
Chemical under pressure, n.o.s.; UN3501, Chemical under pressure, 
flammable, n.o.s.; UN3503, Chemical under pressure, corrosive, n.o.s., 
UN3503; UN3502, Chemical under pressure, toxic n.o.s.; UN3504, Chemical 
under pressure, flammable, toxic, n.o.s.; and UN3505, Chemical under 
pressure, flammable, corrosive, n.o.s.''
Special Provision W10
    A new special provision W10 is added and assigned to HMT entries 
``UN3486 Calcium hypochlorite mixture, dry, corrosive with more than 
10% but not more than 39% available chlorine'' and to ``UN2208 Calcium 
hypochlorite mixtures, dry, with more than 10 percent but not more than 
39 percent available chlorine'' indicating that when offered for 
transportation by vessel, the use of Large Packagings is prohibited. 
This provision is being adopted to align with a recent IMO change 
forbidding these commodities from being transported by vessel in large 
packages.

Section 172.202

    Section 172.202 establishes requirements for shipping descriptions 
on shipping papers. As part of these shipping paper requirements, in 
many situations a net or gross quantity of the hazardous materials 
transported must be included. At the 23rd meeting of the ICAO DGP, the 
issue of notation of quantities on shipping documents was raised. 
Specifically, it was noted that some confusion as to whether or not the 
net quantity or a gross mass is required on the shipping documents on 
particular shipments, such as limited quantities. At this meeting an 
amendment to the ICAO Technical Instructions was proposed and adopted 
designed to clarify what quantities (i.e. net or gross quantity) were 
required on the transport document for packages containing limited 
quantities where different hazardous materials are packed together in 
the same outer packaging.
    In this NPRM, PHMSA proposes to adopt a similar provision to the 
one addressed by the ICAO DGP discussed above. Specifically, PHMSA 
proposes to add a new paragraph (a)(6)(vii) stating that for shipments 
containing hazardous materials in limited quantities with a ``30 Kg 
gross'' limit in Column (9A) or (9B) of the Sec.  172.101 Hazardous 
Materials Table and different hazardous materials packed together in 
the same outer packaging, the net quantity of each hazardous material 
followed by the gross mass of the completed package should be shown on 
the shipping paper.
    This clarification will address a transport scenario currently not 
addressed in the HMR thus alleviating confusion regarding the shipping 
paper requirements of such shipments. Furthermore, this will harmonize 
the HMR with the ICAO Technical Instructions and avoid shipping paper 
discrepancies for international shipments.

Section 172.301

    This section details the general marking requirements for non-bulk 
packagings. Specifically, this section states what information (proper 
shipping name and identification number, technical names, consignee's 
or consignor's name, etc.) must be displayed on the outside of non-bulk 
packages. While the HMR requires that an identification number, 
preceded by ``UN'' or ``NA'' as appropriate, be marked on the outside 
of a non-bulk packaging a specific size of this marking is not 
specified.
    In this NPRM PHMSA proposes to add specific size requirements for 
the ``UN'' or ``NA'' markings. As proposed these markings must be 
marked in characters at least 12 mm (0.47 inches) high, however, 
packages with a maximum capacity of 30 liters (7.92 gallons) or 30 kg 
(66 pounds) or less must be marked with characters at least 6 mm (0.2 
inches) high and packages having a maximum capacity 5 liters (1.32 
gallons) or 5 kg (11 pounds) or less must be marked in a size 
appropriate for the size of the package.
    PHMSA proposes this minimum size marking for the ``UN'' or ``NA'' 
markings to align with newly adopted requirements in the 17th Revised 
Edition of the UN Model Regulations. PHMSA recognizes the importance of 
establishing a minimum size requirement for the internationally 
recognized ``UN'' identification number marking system. The HMR 
currently specifies size requirements for the package markings 
specified in Sec.  178.3(a)(4). Specifically, for package markings, 
letters and numerals must be at least 12.0 mm (0.47 inches) in height 
except that for packagings of less than or equal to 30 L (7.9 gallons) 
capacity for liquids or 30 kg (66 pounds) capacity for solids the 
height must be at least 6.0 mm (0.2 inches). Without a minimum size 
requirement for hazard communication, shippers may mark packages in a 
format that makes it very hard for first responders to identify the 
commodity associated with a particular package. Therefore in this NPRM, 
PHMSA proposes to specify a marking size consistent with package 
marking sizes specified in Sec.  178.3(a)(4) and those adopted in the 
17th Revised Edition of the UN Model Regulations.

Section 172.312

    Section 172.312 details the specific marking requirements for 
liquid hazardous materials in non-bulk packagings. Paragraph (a) of 
this section describes scenarios when package orientation arrows must 
be displayed on the outside of a package. Provided certain criteria are 
met, paragraph (c) excepts certain shipments from the requirements of 
paragraph (a) and thus, the requirement to display the package 
orientation arrows on the package. Currently Sec.  173.312(c)(3) states 
that when offered or intended for transportation by aircraft, packages

[[Page 49190]]

containing flammable liquids in inner packagings of 120 mL (4 fluid 
oz.) or less prepared in accordance with Sec.  173.150(b) or (c) of 
this subchapter when packed with sufficient absorption material between 
the inner and outer packagings to completely absorb the liquid contents 
are not required to display the package orientation arrows on the 
outside of the package. The ICAO TI have been amended to extend this 
exception to the package orientation markings to all liquid hazardous 
materials in inner packagings of 120 mL (4 fluid oz.) when packed with 
sufficient absorption material between the inner and outer packagings 
to completely absorb the liquid contents. In this NPRM, PHMSA is 
proposing to adopt this change, consistent with the amendment made to 
the ICAO TI to extend the exception for the display of the package 
orientation arrows to all liquid hazardous materials in inner 
packagings of 120 mL (4 fluid oz.) when packed with sufficient 
absorption material between the inner and outer packagings to 
completely absorb the liquid contents.

Section 172.604

    Section 172.604 prescribes emergency response telephone number 
requirements. Paragraph (d) of this section provides a listing of 
materials that are excepted from the requirement to provide an 
emergency response telephone number on a shipping document.
    In this NPRM, PHMSA proposes to add ``Krill Meal, PGIII'' to the 
list of materials excepted from the emergency response telephone number 
requirements. Krill meal poses similar hazards to fish scrap and meal; 
therefore, in this NPRM we are providing Krill meal with the same 
exception from the emergency response telephone number requirements as 
fish scrap and meal.

Part 173

    Part 173 of the HMR describes the general requirements for 
shipments and packagings of hazardous materials. Consistent with 
amendments adopted by the UN Model Regulations, PHMSA proposes to adopt 
changes throughout the Part 173 packaging requirements to authorize 
more flexibility when choosing packages for hazardous materials. 
Specifically PHMSA proposes to authorize the use of the following 
packaging types and materials:
    The specific packaging requirements for Class 1 explosive materials 
are specified in Sec.  173.62. In this NPRM PHMSA is proposing to 
revise Sec.  173.62 to authorize wood as an appropriate material used 
to construct receptacles, inner and outer intermediate packagings, and 
intermediate packagings/dividing partitions for certain explosives. 
Furthermore, in this NPRM PHMSA is proposing to authorize the use of 
metals other than steel or aluminum in specification packagings, 
specifically drums (1N1 or 1N2) and boxes (4N), as appropriate. This 
authorization would not include chlorosilanes under Sec.  173.206 
because of corrosion concerns. Otherwise, it authorizes the use of 
closed head drums where open head drums are generally permitted. PHMSA 
believes these amendments would provide greater flexibility in 
packaging while maintaining an equivalent level of safety.
    Consistent with amendments adopted by the ICAO Technical 
Instructions, PHMSA proposes to adopt changes in various sections on 
Part 173 where certain articles, items, and materials are excepted from 
the requirements of the subchapter. There is a potential for these 
excepted articles, items, and materials to be inappropriately carried 
aboard an aircraft by passengers or crewmembers. The proposed changes 
will address this concern by clarifying that certain excepted articles, 
items and materials, identified by ICAO as posing a safety risk, must 
be transported as cargo and cannot be carried onboard an aircraft by 
passengers or crewmembers as carry-on baggage, checked baggage, or on 
their person unless specifically excepted by Sec.  175.10, ``Exceptions 
for Passengers, Crewmembers, and Air Operators.'' The amended sections 
include Sec. Sec.  173.21, 173.159a, 173.162, 173.164, 173.175, 
173.219, and 173.306. For UN3166 and UN3268, Special Provision A200 
will be created to communicate this requirement and a reference to 
special provision A200 would be placed in column 7 of the HMT for these 
entries.

Section 173.12

    This section specifies the exceptions for shipment of waste 
materials including the requirements for waste packages known as ``lab 
packs.'' A lab pack, although not specifically defined in Sec.  171.8, 
is considered a large outer packaging containing small inner packagings 
that are filled with various compatible laboratory hazardous wastes. 
Paragraph (b) of this section specifies the authorized inner and outer 
packagings for lab packs.
    In this NPRM, PHMSA proposes to revise paragraph (b)(2)(ii)(a) of 
this section by adding 1N2 metal drums to the permitted outer 
packagings currently authorized for a lab pack.

Section 173.21

    Section 173.21 prescribes materials and packages forbidden for 
transport. In this NPRM, PHMSA is proposing to correct the IMDG Code 
section reference to control temperature requirements in Sec.  
173.21(f)(3)(ii) from 7.7 to 7.3.7.

Section 173.37

    Currently, the HMR does not include a section that prescribes 
general requirements for packaging hazardous materials in Flexible Bulk 
Containers (FBCs). In this NPRM, PHMSA is proposing such requirements 
in new Sec.  173.37 in a similar format to the general requirements for 
other bulk and large packagings (e.g., portable tanks, IBCs, etc.) in 
subpart B of part 173. This section will include, but not be limited 
to, requirements addressing the initial use and reuse of FBCs, capacity 
requirements and general transport conditions. Consistent with the use 
and reuse requirements of other large and bulk packagings, the general 
requirements in part 173 complement the construction and manufacture 
specifications for such bulk packagings in part 178 of the HMR.
    In this NPRM, PHMSA is proposing that FBCs may be reused, and must 
be given a visual examination prior to reuse. Furthermore, the general 
requirements for FBCs would specify that FBCs must be transported in a 
conveyance with rigid sides and ends that extend at least two-thirds 
the height of the FBC, must not be offered for transportation in 
freight containers, and may not exceed 15 cubic meters in capacity.

Section 173.50

    Section 173.50 provides definitions for the various divisions of 
Class 1 (explosives) referenced in Subpart C of Part 173. Paragraph (b) 
of this section notes that Class 1 (explosives) are divided into six 
divisions. Division 1.6 is described as an explosive consisting ``of 
extremely insensitive articles that do not have a mass explosive 
hazard. This division is comprised of articles that contain only 
extremely insensitive detonating substances and that demonstrate a 
negligible probability of accidental initiation or propagation.''
    In this NPRM PHMSA is proposing to remove the word ``detonating'' 
from this definition to align with the revised definition provided in 
the 17th Revised Edition of the UN Model Regulations.

Section 173.59

    Section 173.59 provides definitions of explosive terms related to 
the transport and classification of explosives used throughout subpart 
C of part 173. These

[[Page 49191]]

definitions are intended for information only and are not to be used 
for purposes of classification or to replace proper shipping names 
prescribed in Sec.  172.101. In the UN Model Regulations, Appendix B to 
Chapter 3 contains a similar list of explosive definitions which are 
also intended for information only and are not to be used for purposes 
of hazard classification.
    In April 2010, the United States and the United Kingdom submitted a 
formal document regarding proposed modifications to the UN test series 
7 for consideration by the UN Subcommittee of Experts on the Transport 
of Dangerous Goods. Test series 7 is used to classify explosives into 
the appropriate class.\2\ This paper sought to modify the test series 7 
to more accurately address the classification of Division 1.6. 
Specifically, Division 1.6 is for extremely insensitive detonating 
articles and the proposed changes in the US/UK paper are designed to 
ensure that the probability of accidental initiation or propagation of 
an article attaining this division remains negligible.
---------------------------------------------------------------------------

    \2\ The scientific data regarding the adoption of these 
modifications are presented in working paper ST/SG/AC.10/C.3/2010/40 
entitled ``Proposed modifications to Test Series 7.'' This paper can 
be viewed at the following URL: http://www.unece.org/fileadmin/DAM/trans/doc/2010/ac10c3/ST-SG-AC10-C3-2010-40e.pdf.
---------------------------------------------------------------------------

    In the 17th Revised Edition of the UN Model Regulations, the 
proposals presented in the US/UK paper regarding the UN test series 7 
were adopted. Among the adopted proposals was the addition of various 
explosive specific definitions referencing the modifications to the UN 
test series 7. In this NPRM, we are proposing to revise the various 
definitions prescribed in Sec.  173.59. Specifically, we propose 
revising the definition for ``Articles, explosive, extremely 
insensitive (Articles, EEI)'' by removing the word ``detonating'' and 
adding the words ``tools'' after ``starter pistols'' in the definition 
for ``Cartridges, blank.'' We also propose to replace the definition 
for ``Explosive, extremely insensitive detonating substances (EIDS)'' 
with a new definition for ``Explosive, extremely insensitive substances 
(EIS).'' Lastly, we propose to add a definition for ``Auxiliary 
explosive component, isolated.'' The addition of and revisions to these 
definitions will provide consistency with international regulations and 
clarity when utilizing the UN test series 7 for explosive 
classification.

Section 173.62

    Section 173.62 prescribes the specific packaging requirements for 
explosives. These packaging requirements stipulate the permitted inner, 
intermediate, and outer packagings as well as any specific additional 
packaging information. These packaging requirements are generally 
aligned with the requirements stipulated in the UN Model Regulations.
    In this NPRM, PHMSA is proposing to revise various packaging 
provisions in the ``Table of Packing Methods'' in this section to align 
with changes adopted in the 17th Revised Edition of the UN Model 
Regulations. The revisions to the authorized packaging methods provide 
greater flexibility when packaging explosives while retaining an 
appropriate level of safety. These changes include, but are not limited 
to, permitting various explosives to be transported in closed head 
drums in addition to the already permitted removable head drums and 
adding the option to utilize wooden inner and intermediate packagings 
in various packaging provisions.

Section 173.63

    Section 173.63 provides packaging exceptions for specific types of 
low hazard explosive materials including certain detonators, small arms 
ammunition and detonating cord. Paragraph (b) of this section 
prescribes the limited quantity requirements for small arms ammunition 
and blank cartridges for tools. Specifically, Sec.  173.63(b)(1)(i) 
authorizes Cartridges, small arms (UN0012), and Cartridges for tools, 
blank used to project fastening devices (UN0014), classed as Division 
1.4S explosive articles, to be offered for transportation and 
transported as limited quantity material when packaged in accordance 
with Sec.  173.63(b)(2) and marked as prescribed in Sec.  172.315(a) or 
(b) for transportation by all modes.

Section 173.115

    Section 173.115 prescribes the definitions for Class 2 materials. 
Paragraph (k) of this section specifies how the oxidizing ability of 
certain Division 2.2 gases is determined. Currently, the HMR references 
ISO standards that include test and calculations used to determine the 
oxidizing ability of certain Division 2.2 gases. The UN Model 
Regulations and the ICAO Technical Instructions replace references to 
ISO standards 10156:1996 and 10156-2:2005 with the updated version ISO 
10156:2010.
    Based on its technical review, PHMSA believes the updated standard 
provides an adequate level of safety and proposes to reference the 
standard in this section and add it to the list of IBR materials in 
Sec.  171.7.

Section 173.121

    Section 173.121 prescribes the requirements for selection of 
packing groups for Class 3 flammable liquids. Paragraph (b) of this 
section describes the criteria for inclusion of viscous Class 3 
materials in Packing Group III.
    ICAO adopted requirements in the Technical Instructions that 
increased the quantity of viscous Class 3 flammable liquids permitted 
reclassification from Packing Group II to Packing Group III from 30 L 
(7.9 gal) per package to 100 L (26.42 gal) per package when offered for 
transport by cargo aircraft.
    In this NPRM, PHMSA proposes to expand the per package amounts of 
viscous Class 3 material meeting the requirements in Sec.  173.121(b). 
The increase will facilitate multi-modal transportation by permitting 
shipments offered by highway, rail, and cargo-carrying aircraft to 
utilize the same 100 L criteria.

Section 173.134

    Provisions contained in the UN Model Regulations, Chapter 2.6, 
Class 6--Toxic and Infectious Substances, relating to the 
transportation of medical devices and equipment, have been amended to 
except medical equipment which has been drained of free liquid from the 
requirements of the UN Model Regulations. In addition, except for 
medical devices or equipment being transported for disposal, or medical 
devices or equipment contaminated with or suspected of contamination 
with a Category A infectious substance, the UN Model Regulations have 
been amended to exempt medical devices or equipment potentially 
contaminated with or containing infectious substances which are being 
transported for disinfection, cleaning, sterilization, repair or 
equipment evaluation from all other requirements of the UN Model 
Regulations, provided they meet certain packaging requirements.
    In this NPRM, PHMSA proposes to amend Sec.  173.134, ``Class 6, 
Division 6.2--Definitions and Exceptions'' by adopting the additional 
exemptions for medical devices and equipment.

Section 173.158

    Section 173.158 prescribes packaging requirements for nitric acid 
mixtures of varying concentrations. In this NPRM, PHMSA is proposing to 
revise the list of outer packagings permitted for nitric acid mixtures 
of varying concentrations.

[[Page 49192]]

    Specifically, PHMSA proposes to revise paragraph (d)(2) by adding 
1N2, 4A, 4B and 4N packagings to the list of authorized outer 
packagings of combination packages for nitric acid of 90 percent or 
greater concentration, when offered for transportation or transported 
by rail, highway, or water, in addition to the packaging options 
currently authorized.
    PHMSA also proposes to revise paragraph (e) of this section 
pertaining to nitric acid of less than 90 percent concentration, when 
offered for transportation or transported by rail, highway, or water. 
Specifically, this paragraph is revised to permit packagings of 
specification 4A, 4B, or 4N metal boxes for certain nitric acid 
concentrations.
    Further, PHMSA proposes to revise paragraphs (f)(3), (g) and (h) by 
adding specification 1N2, 4A, 4B and 4N packagings to the list of 
authorized outer packagings of combination packagings for nitric acid 
of the following concentrations: (1) Nitric acid of 70 percent or less 
concentration, when offered for transportation or transported by rail, 
highway, or water; (2) Nitric acid of more than 70 percent 
concentration, when offered for transportation or transported by cargo 
aircraft only; and (3) Nitric acid of less than 70 percent 
concentration, when offered for transportation in cargo aircraft only.
    The addition of these packaging options will increase flexibility 
for shippers when determining the appropriate packaging for nitric acid 
mixtures, in addition to the packaging options currently authorized.

Section 173.159a

    Section 173.159a provides exceptions for non-spillable batteries. 
Paragraph (d) of this section excepts non-spillable batteries from the 
requirements of the HMR provided certain criteria, including specific 
packaging requirements and the absence of free-flowing liquid in the 
battery, are met.
    In this NPRM, PHMSA is proposing to clarify paragraph (d) of this 
section by adding a new subparagraph (b)(3) stating that ``for 
transport by aircraft, must be transported as cargo.'' This 
clarification will align the HMR with the previously discussed changes 
made to the ICAO TI with regard to the air transport of non-spillable 
batteries that are excepted from the HMR.

Section 173.160

    Section 173.160 prescribes packaging requirements for ``Bombs, 
smoke, non-explosive'' when shipped without ignition devices. In this 
NPRM, PHMSA is proposing to revise the list of packagings permitted for 
``Bombs, smoke, non-explosive'' shipped without ignition devices. 
Specifically, PHMSA proposes to add the authorization to use metal (4A, 
4B, and 4N), fiberboard (4G) or solid plastic (4H2) boxes, or metal 
(1A2, 1B2, and 1N2), plastic (1H2), plywood (1D), or fiber (1G) drums.

Section 173.162

    Section 173.162 prescribes the packaging requirements for ``UN2803, 
Gallium.'' In this NPRM, PHMSA proposes to revise paragraph (a)(1), 
which authorized combination packagings intended to contain liquids 
consisting of glass, earthenware, or rigid plastic inner packagings 
with a maximum net mass of 15 kg (33 pounds) each. Specifically, PHMSA 
proposes to revise these requirements to permit both open and closed 
steel, metal, other that steel and aluminium drums (1A1, 1N1, 1N2, 1H1, 
3A2 or 3H2) in addition to the packaging options currently authorized.
    Further, PHMSA proposes to revise paragraph (a)(2), which 
authorizes packagings intended to contain liquids consisting of semi-
rigid plastic inner packagings of not more than 2.5 kg (5.5 pounds) net 
capacity each, individually enclosed in a sealed, leak-tight bag of 
strong puncture-resistant material. Specifically, PHMSA proposes to 
revise these requirements to permit metal, other than steel or 
aluminium (4N) boxes; metal, other than steel or aluminium drums (1N1, 
1N2); and plastic drums (1H1 or 1H2) in addition to the packaging 
options currently authorized.
    In addition, PHMSA is proposing to clarify paragraph (d) by adding 
a new subparagraph (b)(3) stating that ``for transport by aircraft, 
must be transported as cargo.'' This clarification will align the HMR 
with the previously discussed changes adopted in the ICAO Technical 
Instructions regarding the air transport of gallium otherwise excepted 
from the HMR.

Section 173.164

    Section 173.164 prescribes the packaging requirements for mercury 
(metallic and articles containing mercury). In this NPRM, PHMSA 
proposes to revise paragraph (a)(1), which authorized inner packagings 
of earthenware, glass or plastic containing not more than 3.5 kg (7.7 
pounds) of mercury, or inner packagings that are glass ampoules 
containing not more than 0.5 kg (1.1 pounds) of mercury, or iron or 
steel quicksilver flasks containing not more than 35 kg (77 pounds) of 
mercury. Specifically, PHMSA proposes to revise these requirements to 
permit steel drums; metal, other that steel and aluminum drums (1A1, 
1N1, 1N2) and metal, other than steel or aluminum boxes (4N), in 
addition to the packaging options currently authorized in paragraphs 
(a), (b) and (c).
    Paragraph (f) is added to provide an exception to the requirements 
of the HMR for vessel transport of manufactured articles or instruments 
containing less than 0.45 kg (1.0 pound) of mercury. This exception is 
inserted to mirror an existing IMDG Code provision and harmonize the 
requirements for vessel shipments of mercury contained in manufactured 
articles as much as possible.
    In addition, PHMSA is proposing to clarify paragraphs (a)(5), (b), 
and (c)(2) of this section by adding the phrase ``when transported as 
cargo.'' This clarification will align the HMR with the previously 
discussed changes adopted in the ICAO Technical Instructions regarding 
the air transport of manufactured articles containing mercury otherwise 
excepted from the HMR.

Section 173.165

    Section 173.165 prescribes the transport and packaging requirements 
for polyester resin kits. In this NPRM, PHMSA is proposing to revise 
Sec.  173.165 to better align the packaging and other requirements for 
UN3269, Polyester resin kits with the various international modal 
standards. These proposed amendments are also intended to correct 
inconsistencies adopted in a final rule published in the Federal 
Register on January 19, 2011 (76 FR 3308; HM-215K).

Section 173.175

    Section 173.175 prescribes the transport and packaging requirements 
for permeation devices. Currently, permeation devices containing 
hazardous materials that are used for calibrating air quality 
monitoring devices are not subject to the HMR provided they meet 
specific requirements that include packaging, quantity limitations, 
testing, and transport controls.
    In this NPRM, PHMSA is proposing to add a new paragraph (g) stating 
that ``for transport by aircraft, must be transported as cargo.'' This 
clarification will align the HMR with changes adopted in the ICAO 
Technical Instructions regarding the air transport of permeation 
devices that are otherwise excepted from the HMR.

[[Page 49193]]

Section 173.176

    Electric double layer capacitors are devices that store but do not 
produce electrical energy. They contribute to increased fuel efficiency 
in many alternative energy solutions such as hybrid vehicles. Some 
double layer capacitors contain flammable liquid absorbed in a solid 
with small amounts present as free liquid while others use a liquid 
electrolyte. Currently, the HMR do not contain specific requirements to 
address the transport of electric double layer capacitors.
    New Section 173.176 addresses electric double layer capacitors and 
is proposed in this NPRM. If adopted, the section would prescribe the 
testing, marking, safety, and packaging requirements for electric 
double layer capacitors with an energy storage capacity greater than 
0.3 Wh. PHMSA proposes to incorporate these requirements consistent 
with the 17th Revised Edition of the UN Model Regulations. The proposed 
amendments in this NPRM address potential electrical and other hazards 
arising from the release of hazardous materials during the 
transportation of these articles.

Section 173.181

    Section 173.181 prescribes the non-bulk packaging requirements 
applicable to pyrophoric liquids. Paragraph (b) of this section 
specifies the specification boxes authorized to package these 
substances. In this NPRM, PHMSA proposes to revise paragraph (b) by 
adding packaging authorizations for steel boxes (4A), aluminum boxes 
(4B), metal boxes, other than steel or aluminum (4N), or fiberboard 
boxes (4G); steel drums (1A1 or 1A2), aluminum drums (1B1 or 1B2), 
metal drums, other than steel or aluminum (1N1 or 1N2), plywood drums 
(1D), or fiber drums (1G); or steel jerricans (3A1 or 3A2) or aluminum 
jerricans (3B1 or 3B2).

Section 173.183

    Section 173.183 prescribes the packaging requirements for 
nitrocellulose base film. To provide greater flexibility in packaging 
selection, PHMSA proposes to add packaging options to the list 
currently permitted for nitrocellulose base film. Specifically, in this 
NPRM, PHMSA proposes to add other metal drums (4A2), aluminum jerricans 
(3B2), and steel, aluminum or other metal (4A, 4B, 4N) boxes, to the 
list of authorized packagings.

pyrophoric solids, metals or alloys, n.o.s. To provide greater 
flexibility in packaging selection, PHMSA proposes to add packaging 
options to the list permitted for pyrophoric solids, metals or alloys, 
n.o.s. specified in paragraph (a) and (d) of this section. 
Specifically, in this NPRM, PHMSA proposes to add steel, aluminum or 
other metal boxes (4A, 4B or 4N), to the list of authorized packagings 
in paragraph (a). In addition, PHMSA proposes to add steel, aluminum or 
other metal drums (1A1, 1A2, 1B1, 1B2, 1N1 or 1N2) to the list of 
authorized packagings in paragraph (d).

Section 173.188

    Section 173.187 prescribes the packaging requirements for white and 
yellow phosphorus. To provide greater flexibility in packaging 
selection, PHMSA proposes to add packaging options to the list 
permitted for white and yellow phosphorus specified in paragraphs 
(a)(1) and (a)(2) of this section. Specifically, in this NPRM, PHMSA 
proposes to add steel, aluminum or other metal boxes (4A, 4B or 4N), to 
the list of authorized packagings in paragraph (a)(1). In addition, 
PHMSA proposes to add steel, aluminum or other metal drums (1A1, 1B1 or 
1N1) not over 250 L (66 gallons) capacity each and steel, aluminum or 
other metal drums (1A2, 1B2, or 1N2) not over 115 L (30 gallons) 
capacity each, to the list of authorized packagings in paragraph 
(a)(2).

Section 173.189

    Section 173.189 prescribes the packaging and transport requirements 
for batteries containing sodium or cells containing sodium. To provide 
greater flexibility in packaging selection, PHMSA proposes to add 
packaging options to the list permitted for batteries containing sodium 
or cells containing sodium specified in paragraph (b) of this section. 
Specifically, in this NPRM, PHMSA proposes to add 1N2, 4A, 4B, 4N, 4H1, 
3A2, 3B3 and 3H2 outer packagings to the list of authorized outer 
packagings in paragraph (b).

Section 173.193

    Section 173.193 prescribes the packaging requirements for 
bromoacetone, methyl bromide, chloropicrin and methyl bromide or methyl 
chloride mixtures. To provide greater flexibility in packaging 
selection, PHMSA proposes to add packaging options to this list 
permitted for bromoacetone, methyl bromide, chloropicrin and methyl 
bromide or methyl chloride mixtures specified in paragraph (a) of this 
section. Specifically, in this NPRM, PHMSA proposes to add metal boxes 
(4A, 4B or 4N) to the list of authorized outer packagings in paragraph 
(a).

Section 173.194

    Section 173.194 prescribes the packaging requirements for gas 
identification sets. To provide greater flexibility in packaging 
selection, PHMSA proposes to add packaging options to the list 
permitted for gas identification sets specified in paragraphs (b)(1) 
and (b)(2) of this section. Specifically, in this NPRM, PHMSA proposes 
to add metal boxes (4A, 4B or 4N) to the list of authorized outer 
packagings in paragraphs (b)(1) and (b)(2).

Section 173.196

    Section 173.196 prescribes the packaging requirements for Category 
A infectious substances. To provide greater flexibility in packaging 
selection, PHMSA proposes to add packaging options to the list 
permitted for category A infectious substances specified in paragraph 
(a)(3) of this section. Specifically, in this NPRM, PHMSA proposes to 
add drums (1A1, 1A2, 1B1, 1B2, 1N1, 1N2, 1H1, 1H2, 1D, 1G); boxes (4A, 
4B, 4N, 4C1, 4C2, 4D, 4F, 4G, 4H1, 4H2); or jerricans (3A1, 3A2, 3B1,

[[Page 49194]]

3B2, 3H1, 3H2) as examples of the types of authorized ``rigid outer 
packaging'' referenced in paragraph (a)(3).

Section 173.199

    Section 173.199 prescribes the packaging requirements for category 
B infectious substances. Paragraph (d) of this section provides the 
requirements for refrigerated or frozen specimens in ice, dry ice or 
liquid nitrogen. These provisions include the requirement to secure 
secondary packages.
    Consistent with an editorial amendment to Packing Instruction P650 
in the 17th Revised Edition of the UN Model Regulations, in this NPRM, 
PHMSA proposes to remove the language ``position after the ice or dry 
ice has dissipated'' from the requirements to secure secondary 
packages.

Section 173.201

    Section 173.201 prescribes the authorized non-bulk packagings for 
liquid hazardous materials in packing group I. To provide greater 
flexibility in packaging selection, PHMSA proposes to add packaging 
options to the list permitted for non-bulk packagings used to package 
liquid hazardous materials in packing group I indicated in paragraph 
(b). Specifically, in this NPRM, PHMSA proposes to add ``Metal box 
other than steel or aluminum: 4N'' to authorized outer packagings of 
combination packagings listed in paragraph (b) of this section.

Section 173.202

    Section 173.202 prescribes the authorized non-bulk packagings for 
liquid hazardous materials in packing group II. To provide greater 
flexibility in packaging selection, PHMSA proposes to add packaging 
options to the list permitted for non-bulk packagings used to package 
liquid hazardous materials in packing group II specified in paragraph 
(b). Specifically, in this NPRM, PHMSA proposes to add ``Metal box 
other than steel or aluminum: 4N'' to the authorized outer packagings 
of combination packagings indicated in paragraph (b).

Section 173.203

    Section 173.203 prescribes the authorized non-bulk packagings for 
liquid hazardous materials in packing group III. To provide greater 
flexibility in packaging selection, PHMSA proposes to add packaging 
options to the list permitted for non-bulk packagings used to package 
liquid hazardous materials in packing group III specified in paragraph 
(b). Specifically, in this NPRM, PHMSA proposes to add ``Metal box 
other than steel or aluminum: 4N'' to the authorized outer packagings 
of combination packagings indicated in paragraph (b).

Section 173.211

    Section 173.211 prescribes the authorized non-bulk packagings for 
hazardous materials in packing group I. To provide greater flexibility 
in packaging selection, PHMSA proposes to add packaging options to the 
list permitted for non-bulk packagings used to package hazardous 
materials in packing group I specified in paragraphs (b) and (c). 
Specifically, in this NPRM, PHMSA proposes to add ``Metal box other 
than steel or aluminum: 4N'' to the authorized outer packagings of 
combination packagings indicated in paragraph (b) and the single 
packagings authorized in paragraph (c).

Section 173.212

    Section 173.212 prescribes the authorized non-bulk packagings for 
hazardous materials in packing group II. To provide greater flexibility 
in packaging selection, PHMSA proposes to add packaging options to the 
list permitted for non-bulk packagings used to package hazardous 
materials in packing group II specified in paragraphs (b) and (c). 
Specifically, in this NPRM, PHMSA proposes to add ``Metal box other 
than steel or aluminum: 4N'' to authorized outer packagings of 
combination packagings indicated in paragraph (b). Further, PHMSA 
proposes to add ``Metal box other than steel or aluminum: 4N'' and 
``Metal box other than steel or aluminum with liner: 4N'' to authorized 
single packagings permitted in paragraph (c) of this section.

Section 173.213

    Section 173.213 prescribes the authorized non-bulk packagings for 
hazardous materials in packing group III. To provide greater 
flexibility in packaging selection, PHMSA proposes to add packaging 
options to the list permitted for non-bulk packagings used to package 
hazardous materials in packing group III specified in paragraphs (b) 
and (c). Specifically, in this NPRM, PHMSA proposes to add ``Metal box 
other than steel or aluminum: 4N'' to the authorized outer packagings 
of combination packagings indicated in paragraph (b). Further, PHMSA 
proposes to add ``Metal box other than steel or aluminum: 4N'' and 
``Metal box other than steel or aluminum with liner: 4N'' to the single 
packagings authorized in paragraph (c).

Section 173.219

    Section 173.219 prescribes the transport conditions and packaging 
requirements for life saving appliances. Paragraph (b) of this section 
provides a list of hazardous materials that a life-saving appliance is 
permitted to contain as well as other transport requirements. 
Currently, the transport conditions specified in paragraph (b)(1) of 
this section specify that Division 2.2 compressed gases, including 
oxygen are permitted; however, oxygen generators are not. In this NPRM, 
PHMSA proposes to broaden the materials permitted in life-saving 
appliances by modifying paragraph (b)(1) to include liquefied gases as 
well.
    Paragraph (c) of this section prescribes the packaging requirements 
and exceptions provided for life saving appliances. Subsequent changes 
are proposed to paragraph (c)(1) of this section to reflect this 
inclusion of liquefied gases discussed previously. Furthermore, 
paragraph (c)(5) currently states that, for other than transportation 
by aircraft, life-saving appliances containing no hazardous materials 
other than carbon dioxide with a capacity not exceeding 100 cm\3\ are 
not subject to the provisions of this subchapter provided they are 
overpacked in rigid outer packagings with a maximum gross mass of 40 
kg. In this NPRM, PHMSA is proposing to revise the exception in (c)(5) 
by replacing the language ``carbon dioxide'' with ``cylinders of 
Division 2.2 compressed or liquefied gases with no subsidiary risk,'' 
and the quantity limit ``100 cm\3\ with ``120 ml, installed solely for 
the purpose of activating the appliance.''
    In addition, PHMSA proposes to further clarify paragraph (c)(5) of 
this section by adding the statement, ``For transportation by aircraft, 
such appliances must be transported as cargo.'' This clarification 
aligns the HMR with the recently adopted changes in the ICAO Technical 
Instructions regarding the air transport of life saving appliances that 
would otherwise be excepted from the HMR.

Section 173.221

    Section 173.221 prescribes the non-bulk packaging requirements for 
Polymeric beads (or granules), expandable, evolving flammable vapor and 
Plastic molding compound in dough, sheet or extruded rope form, 
evolving flammable vapor. In this NPRM, PHMSA is proposing to add the 
following packaging authorizations; metal (4A, 4B, or 4N), and plastic 
(4H1 or 4H2) drums, and 1N1, 1N2 drums in vapor tight metal or plastic 
jerricans

[[Page 49195]]

(3A1, 3A2, 3B1, 3B2, 3H1, or 3H2). PHMSA is also proposing to add a 
paragraph to the section that will reference the reader to a newly 
created Sec.  176.907 for cargo transport and hazard communication 
marking requirements for shipments of Polymeric beads expandable, 
evolving flammable vapor and Plastic molding compound in dough, sheet 
or extruded rope form, evolving flammable vapor when transported by 
vessel. These changes are proposed to address the safety hazard 
presented by shipments of polymeric beads or plastic molding compounds 
off-gassing flammable vapors during vessel transport. See Section 
176.907 for a detailed discussion of our proposed addition of these 
vessel cargo transport requirements.

Section 173.225

    Section 173.225 prescribes the packaging requirements and other 
provisions for organic peroxides. Packaging requirements for organic 
peroxides are very specific and include requirements for the 
concentration by mass permitted, diluents percentage, water mass, 
temperature controls and organic peroxide specific packing methods.
    Paragraph (c) of this section contains and describes the organic 
peroxide table and how specific organic peroxides are to be 
transported. In addition, paragraph (e) contains a separate table that 
prescribes the packaging requirements for organic peroxides packaged in 
IBCs. As self-insulating hazardous materials, organic peroxides can 
pose different risks when transported in larger quantities. Thus, a 
separate table unique to the transport of these substances in IBCs is 
contained in the HMR. The ``Organic Peroxide IBC Table'' includes 
maximum quantities permitted to be packaged and any temperature and 
emergency controls.
    The organic peroxides tables in paragraphs (c) and (e) specify by 
technical name those organic peroxides that are authorized for 
transportation and not subject to the approval provisions of Sec.  
173.128. An organic peroxide identified by technical name is authorized 
for transportation only if it conforms to all applicable provisions of 
these tables. In this NPRM, we are proposing to amend the Organic 
Peroxides Tables in Sec.  173.225 by adding new entries and revising 
current entries to account for new organic peroxides and formulations 
that are commercially available.
    The following entries are added in the Sec.  173.225(c) organic 
peroxides table:

UN3106, ``([3R-(3R,5aS,6S,8aS,9R,10R,12S,12aR**)]-Decahydro-10methoxy-
3,6,9-trimethyl-3,12-epoxy-12H-pyrano[4,3-j]-1,2-benzodioxepin)''
UN3110, ``3,6,9-Triethyl-3,6,9-trimethyl-1,4,7-triperoxonane''
UN3119, ``Di-(3,5,5-trimethylhexanoyl) peroxide''

    The following current entries in the Sec.  173.225(c) organic 
peroxides table are amended:

UN3115, ``Diisopropyl peroxydicarbonate''
UN3115, ``Di-(3,5,5-trimethylhexanoyl) peroxide''

    The following entries are added to the Sec.  173.225(e) Organic 
Peroxide IBC Table:

UN3119 ``Diisobutyryl peroxide, not more than 28% as a stable 
dispersion in water''
UN3119, ``Diisobutyryl peroxide, not more than 42% as a stable 
dispersion in water''

    The following entries are amended in the Sec.  173.225(e) Organic 
Peroxide IBC Table:

UN3119 ``Di-(3,5,5-trimethylhexanoyl) peroxide, not more than 38% in 
diluent type A''
UN3119 ``1,1,3,3-Tetramethylbutyl peroxyneodecanoate, not more than 
52%, stable dispersion, in water''

Section 173.226

    Section 173.226 prescribes the packaging requirements for Materials 
poisonous by inhalation, Division 6.1, Packing Group I, Hazard Zone A. 
Specifically, this section authorizes the transport of Materials 
poisonous by inhalation, Division 6.1, Packing Group I, Hazard Zone A 
in specification cylinders, specification drums packaged further in 
specification drums and combination packages. In this NPRM, PHMSA 
proposes to revise the requirements of paragraph (c) by adding an 
authorization to package such materials in ``Metal box other than steel 
or aluminum: 4N'' drums. In addition, PHMSA is correcting an editorial 
error by replacing the incorrect wording ``Expanded plastic box: 4H2'' 
with the correct wording ``Expanded plastic box: 4H1.''

Section 173.230

    Section 173.230 prescribes the transport requirements for fuel cell 
cartridges containing hazardous material. Paragraph (e) of this section 
prescribes the packaging requirements for fuel cell cartridges 
containing hazardous material. Furthermore, paragraph (e)(2)(ii) notes 
that ``Fuel cell cartridges contained in equipment must be protected 
against short circuits and the entire fuel cell system must be 
protected from unintentional activation. The equipment must be securely 
cushioned in the outer packaging.'' As currently stated in the HMR, 
this requirement may imply that only fuel cell cartridges contained in 
equipment, not the fuel cell system, would have to be protected against 
short circuits. This is not the intent of this requirement. Therefore, 
in this NPRM, PHMSA is proposing to clarify that the entire fuel cell 
system must be protected against short circuits and unintentional 
activation.

Section 173.240

    Section 173.240 prescribes the bulk packagings authorized for 
certain low hazard solid materials. As discussed previously in this 
NPRM, PHMSA is proposing the adoption of flexible bulk container 
provisions throughout the HMR.
    In this section, PHMSA proposes to add paragraph (f) that 
authorizes the use of FBCs for certain low hazard solid materials. 
Specifically, paragraph (f) will permit the use of FBCs if B120 is 
indicated in Column (7) of the specific entry in Sec.  172.101 HMT and 
the FBC conforms to the requirements in subparts R and S of part 178 of 
the HMR. Furthermore, paragraph (f) notes that FBCs may not be used for 
Packing Group I or II hazardous materials. Only select low hazard solid 
materials are authorized for transport in FBCs. The use of FBCs for the 
transportation of an HMT entry not assigned special provision B120 is 
prohibited.

Section 173.306

    Section 173.306 prescribes the exceptions for limited quantities of 
compressed gases including aerosols. Paragraph (a) of this section 
prescribes the general requirements for limited quantities of 
compressed gases while paragraph (j) specifically addresses aerosols 
and receptacles small, containing gas, with a capacity of less than 50 
mL.
    In this NPRM, PHMSA proposes to revise paragraph (j) to note that 
aerosols conforming to this paragraph, when offered for transportation 
by air, must be transported as cargo unless specifically authorized for 
transport in checked or carry-on baggage. This clarification will align 
the HMR with the previously discussed changes adopted in the ICAO 
Technical Instructions regarding the air transport of aerosols that are 
otherwise excepted from the HMR.

Section 173.313

    Section 173.313 contains instructions for UN portable tanks and the 
table for

[[Page 49196]]

liquefied compressed gases. The UN Portable Tank Table for Liquefied 
Compressed Gases is referenced in Sec.  172.102(c)(7)(iii) of the HMR 
for portable tanks used to transport liquefied compressed gases.
    Chemical manufacturers throughout the world are currently supplying 
pressurized products contained and transported in gas cylinders. The 
products are liquids or solids such as adhesives, coatings and cleaners 
combined with a gas or gas mixtures in pressure receptacles under 
sufficient pressure to expel the contents. These mixtures are typically 
expelled from the pressurized receptacles as foams, streams or thick 
sprays. Under the current HMR these types of products are classified as 
liquefied gases and transported in accordance with the applicable 
sections for the liquefied gases in which they are classified. A 
typical product however is a combination of a propellant (gas phase) 
and a liquid or solid component, and therefore the term liquefied gas 
does not correctly reflect the contents. As they are not filled in 
aerosol dispensers and as the receptacles used exceed the volume 
limitations for aerosols, they may not be transported as aerosols. The 
United Nations Sub-Committee of experts on the Transportation of 
Dangerous goods agreed to create new entries (UN numbers) for these 
products to address their unique characteristics and corresponding 
regulations to address the safe transport of such materials.
    In this NPRM we are proposing the adoption of entries in the HMT 
for various chemicals under pressure and the corresponding packaging 
provisions. In this NPRM, we propose to modify Sec.  173.313 to include 
the packaging requirements for chemicals under pressure transported in 
portable tanks. Specifically, we propose to revise the section title, 
introductory test, and table name to reflect that chemicals under 
pressure are addressed in this section. We also propose to add table 
entries for identification numbers UN3500, UN3501, UN3502, UN3503, 
UN3504 and UN3505. Lastly, we propose to correct the maximum filling 
density for UN3220.
    The addition of packaging requirements specific to chemicals under 
pressure will ensure that an appropriate level of safety is achieved 
for these unique materials. PHMSA participated in, and concurs with, 
the discussions and decisions regarding the packagings selected for 
these materials. The packagings adopted by the UN, ICAO and IMO provide 
an appropriate level of safety for these materials and, thus, PHMSA 
proposes adopting similar packagings in the HMR. Furthermore, aligning 
with international packaging standards will facilitate the movement of 
these materials both domestically and internationally.

Section 173.316

    Section 173.316 provides the requirements for cryogenic liquids 
contained in cylinders. Specifically, the HMR requires each cylinder 
containing cryogenic liquids be equipped with one or more pressure 
relief devices.
    PHMSA proposes to revise Sec.  173.316, ``Cryogenic Liquids in 
Cylinders'' to include a requirement consistent with the UN Model 
Regulations that all pressure relief device inlets must under maximum 
filling conditions be situated in the vapor space of the closed 
cryogenic receptacle and the devices must be so arranged as to ensure 
that the escaping vapor is discharged unobstructed.
    This requirement would enhance safety by assisting in the proper 
function of the pressure release devices. Further, it would prevent 
unsafe conditions in transport if the liquid form of the gas were 
released through the pressure release device. For instance, if the gas 
released is a Division 2.1 (flammable) gas or a Division 2.3 
(poisonous) gas, it would reduce the opportunity for the released 
liquid form of the gas to create an asphyxiant environment through the 
rapid displacement of the normal concentration of oxygen in the 
breathable atmosphere. Finally, it would reduce the potential of 
released cryogenic oxygen in liquid form to create an oxygen enriched 
atmosphere that may explosively combust.

Section 173.318

    Section 173.318 provides the requirements for cryogenic liquids 
contained in cargo tanks. Specifically, the HMR requires each cargo 
tanks containing cryogenic liquids be equipped with one or more 
pressure relief devices.
    PHMSA proposes to revise Sec.  173.318, ``Cryogenic Liquids in 
Cargo Tanks'' to include a requirement consistent with the UN Model 
Regulations that all pressure relief device inlets shall under maximum 
filling conditions be situated in the vapor space of the closed 
cryogenic receptacle and the devices shall be so arranged as to ensure 
that the escaping vapor is discharged unobstructed.
    This requirement would enhance safety by assisting in the proper 
function of the pressure release devices. Further, it would prevent 
unsafe conditions in transport if the liquid form of the gas were 
released through the pressure release device. For instance, if the gas 
released is a Division 2.1 (flammable) gas or a Division 2.3 
(poisonous) gas, it would reduce the opportunity for the released 
liquid form of the gas to create an asphyxiant environment through the 
rapid displacement of the normal concentration of oxygen in the 
breathable atmosphere. Finally it would reduce the chance of released 
cryogenic oxygen in liquid form creating an oxygen enriched atmosphere 
that may explosively combust.

Section 173.335

    Section 173.335 is created to provide packaging requirements for 
new HMT entries ``Chemical under pressure n.o.s.'' Specifically, PHMSA 
is proposing the transport requirements, filling limits, minimum 
service pressure, and periodic inspection requirements for cylinders 
utilized for shipments of chemical under pressure n.o.s.
    Cylinders used to ship chemical under pressure n.o.s. must be 
authorized UN or DOT cylinders for the propellant and otherwise conform 
to the applicable requirements of subpart G of part 173.

Section 173.340

    Section 173.340 prescribes the packaging requirements for NA1693, 
tear gas devices. Paragraphs (c) and (d) prescribe the authorized 
packagings for tear gas devices. In this NPRM, PHMSA is proposing to 
revise the packaging requirements in paragraphs (c) and (d) by 
authorizing the use of 4A, 4B, or 4N metal boxes, and 1B2, 1N2, or 1H2 
drums.

Part 175

Section 175.8

    Section 175.8 provides exceptions from certain regulations for air 
carrier operator equipment and items of replacement, as well as for 
items used to provide customer service aboard an aircraft.
    ICAO reviewed and revised the Technical Instructions applicable to 
exceptions from certain regulations for air carrier operator equipment 
and items of replacement, and to better reflect items that may be sold 
as part of duty free services. Consistent with the ICAO Technical 
Instructions, in this NPRM, PHMSA is proposing to revise paragraph 
(a)(3)(ii) to clarify that wet cell aircraft batteries up to 100 kg net 
mass per package may be transported. Additionally, lithium ion aircraft

[[Page 49197]]

batteries in packages containing a single aircraft battery with a net 
mass not exceeding 35 kg may be transported. Lastly, PHMSA proposes to 
revise paragraph (b)(2) of this section to add portable electronic 
devices containing lithium batteries to the list of items permitted 
aboard an aircraft for use or sale on that specific aircraft.

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 to revise paragraph (a)(14), the 
conditions under which electrically powered heat-producing articles may 
be carried aboard an aircraft. The requirement that the heat-producing 
component, or the energy source, must be removed to prevent 
unintentional functioning during transport is being revised to permit 
the removal of another component, such as a fuse, to prevent 
unintentional functioning during transport. In addition the paragraph 
is being revised to specify procedures for protecting any removed 
battery from short circuit during transport. PHMSA is also proposing to 
add paragraphs (a)(20), (a)(21), (a)(22), (a)(23), and (a)(24) to 
specify conditions under which permeation devices for calibrating air 
quality monitoring equipment, internal combustion or fuel cell engines, 
non-infectious specimens, insulated packagings containing refrigerated 
liquid nitrogen, and small compressed gas cartridges fitted into 
devices, respectively, may be carried aboard an aircraft.

Part 176

Section 176.2

    Section 176.2 provides definitions of terms specifically as they 
pertain to Part 176. In this NPRM, PHMSA is proposing various revisions 
to the vessel stowage and segregation requirements specified in Part 
176. As part of these changes certain terminology must be defined.
    The term ``Closed cargo transport unit for Class 1'' is defined by 
the IMDG Code as a freight container or transport vehicle that fully 
encloses the contents by permanent structures and can be secured to the 
ship's structure and are, except for the carriage of division 1.4 
explosives, structurally serviceable (see Sec.  176.172). Portable 
magazines conforming to Sec.  176.137 are also considered closed cargo 
transport units for Class 1. Small compartments such as deck houses and 
mast lockers are included. Cargo transport units with fabric sides or 
tops are not closed cargo transport units. The floor of any closed 
cargo transport unit must either be constructed of wood, close-boarded 
or so arranged that goods are stowed on sparred gratings, wooden 
pallets or dunnage. The IMO adopted this new definition for ``closed 
cargo transport unit for Class 1'' to define the characteristics 
required for cargo transport units carrying explosives by vessel.
    A new definition for ``potential or possible sources of ignition'' 
was adopted by the IMO for incorporation in the next published IMDG 
Code. The term ``Potential or possible sources of ignition'' as defined 
in the IMDG Code ``means but is not limited to, open fires, machinery 
exhausts, galley uptakes, electrical outlets and electrical equipment 
including those on refrigerated or heated cargo transport units unless 
they are of a type designed to operate in a hazardous environment. The 
text ``means but is not limited to'' indicates that the list of 
potential or possible sources of ignition is not all inclusive; as it 
is impossible to identify in a definition all potential or possible 
sources of ignition that may exist on a variety of vessels with various 
engineering designs and stowage configurations. Adoption of this 
definition will provide guidance to vessel stowage planners in 
determining safe stowage locations for cargo on board vessels.
    The term ``Protected from sources of heat'' as defined by the IMDG 
Code means ``that packages and cargo transport units must be stowed at 
least 2.4 m from heated ship structures, where the surface temperature 
is liable to exceed 131[emsp14][deg]F (55 [deg]C). Examples of heated 
structures are steam pipes, heating coils, top or side walls of heated 
fuel and cargo tanks, and bulkheads of machinery spaces. In addition, 
packages not loaded inside a cargo transport unit and stowed on deck 
must be shaded from direct sunlight. The surface of a cargo transport 
unit can heat rapidly when in direct sunlight in nearly windless 
conditions and the cargo may also become heated. Depending on the 
nature of the goods in the cargo transport unit and the planned voyage 
precautions must be taken to ensure that exposure to direct sunlight is 
reduced''. This definition was adopted by the IMO for inclusion in the 
next IMDG Code to provide a list of possible sources of heat a cargo 
transport unit might encounter during vessel transport. This definition 
also includes requirements for break bulk packages stowed on deck that 
are required to be protected from sources of heat by means of a stowage 
provision or a general stowage requirement found in Part 176.
    Therefore, in the NPRM PHMSA proposes to add definitions in this 
section for the terms, ``Closed cargo transport unit for Class 1,'' 
``Potential or possible sources of ignition'' and ``Protected from 
sources of heat'' with additional text clarifying that a portable 
magazine conforming to Sec.  176.137 is also considered ``closed cargo 
transport unit for Class 1.''

Section 176.63

    Section 176.63 prescribes supplementary requirements with respect 
to the stowage of specific hazardous materials in addition to those 
authorized in the HMT in Sec.  172.101. This section sets forth the 
basic physical requirements for the authorized vessel stowage 
locations.
    In this NPRM PHMSA proposes to revise paragraph (b) of this section 
by replacing the phrase ``shade from radiant heat'' with the phrase 
``protected from sources of heat.'' This revision of terminology is 
necessary to incorporate other proposed changes to the vessel stowage 
codes in Column 10 B of the HMT proposed in this NPRM.
    In this NPRM PHMSA also proposes changes to paragraph (e) of this 
section, as the definition of ``closed cargo transport unit for Class 
1'' was added to Sec.  176.2 references to magazine stowage type A and 
C are no longer needed in this section.
    Paragraph (e) also contains an exception for empty packages 
containing residue (excluding Class 2.3 empty packages containing 
residue and waste aerosols), including IBCs and large packages to be 
stowed on deck, or under deck if in a mechanically ventilated cargo 
space. This exception would apply regardless of the stowage provisions 
indicated in Sec.  172.101(k). PHMSA believes the reduced hazard 
present in empty packages containing residue combined with the 
mechanically ventilated cargo space warrants a relaxation of stowage 
requirements for shipments of empty packages (excluding Class 2.3 and 
waste aerosols) that otherwise would require on deck stowage.

Section 176.76

    Section 176.76 specifies the requirements for transport vehicles, 
freight containers, and portable tanks containing hazardous materials 
transported via vessel. Currently paragraph (a)(9) of this section 
states that when security devices, beacons or other tracking or 
monitoring equipment are used, they must be securely installed

[[Page 49198]]

and must be of a certified safe type for the hazardous materials that 
will be carried within the freight container or transport vehicle in 
which such as device or equipment is installed.
    In this NPRM PHMSA proposes to replace the existing text in 
paragraph (a)(9) with new text requiring that banding or securing 
straps used to secure packages must not be over tightened to cause 
damage or deformation of the packages or the securing points within the 
freight container or transport vehicle. PHMSA proposes this change to 
harmonize cargo securement requirements in the HMR with recently 
adopted changes in the IMDG Code. This requirement is intended to 
prevent undue stress and potential damage to packages and tie down 
points during transport.

Section 176.83

    Section 176.83 prescribes the general vessel segregation 
requirements. Paragraph (m) of this section specifies additional 
segregation requirements for certain groups of hazardous materials. 
Paragraph (m)(2) of this section prescribes segregation requirements 
for materials shipped under n.o.s. entries. Furthermore, paragraph 
(m)(3) discusses materials that fall outside the defining criteria for 
hazardous materials, but display chemical properties similar to 
hazardous materials listed in segregation groups.
    In this NPRM PHMSA is proposing to revise paragraph (m)(2) to 
clarify that the offeror of hazardous materials is responsible for 
deciding if allocation of a segregation group is appropriate. PHMSA is 
also proposing to revise paragraph (m)(3) to clarify that the offer of 
hazardous materials for transportation or the person packing the cargo 
transport unit is responsible for identifying a relevant segregation 
group and applying the segregation requirements for that segregation 
group. These revisions will replace the current term ``shipper,'' which 
is not defined in Sec.  171.8, with the terms ``offeror'' and ``person 
who offers'' which are defined terms in Sec.  171.8.

Section 176.84

    Section 176.84 prescribes the meanings and requirements for 
numbered or alpha-numeric stowage provisions for vessel shipments 
listed in column 10B of the Sec.  172.101 Hazardous Materials Table. 
The provisions in Sec.  176.84 are broken down into general stowage 
provisions whose meanings are defined in the ``table of provisions'' in 
paragraph (b), and the stowage provisions applicable to vessel 
shipments of Class 1 explosives defined in the table to paragraph 
(c)(2).
    In this NPRM, PHMSA is proposing to revise stowage provisions 25 
and 128 and delete stowage provisions 19, 48, and 50 from the table in 
paragraph (b). Stowage provision 25 is revised from ``Shade from 
radiant heat'' to read ``Protected from sources of heat.'' Stowage 
provision 128 is revised from ``Stow in accordance with the IMDG Code, 
Sub-section 7.1.10.3 (incorporated by reference; see Sec.  171.7 of 
this subchapter)'' to read ``Stow in accordance with the IMDG Code, 
Sub-section 7.6.2.7.2 (incorporated by reference; see Sec.  171.7 of 
this subchapter).'' Deleted stowage provision 19 previously read 
``Protect from sparks and open flames.'' Deleted stowage provision 48 
previously read ``Stow ``away from'' sources of heat''. Deleted stowage 
provision 50 previously read ``Stow ``away from'' sources of heat where 
temperatures in excess of 55 [deg]C (131[emsp14][deg]F) for a period of 
24 hours or more will be encountered.''
    The current stowage provision table in paragraph (b) contains three 
listings requiring shipments to be either shaded or stowed away from 
sources of heat. The addition of a standard definition for ``protected 
from sources of heat'' to the list of definitions in Sec.  176.2 has 
rendered stowage provisions 19, 48, and 50 redundant and all HMT 
listings previously assigned stowage provisions 19 or 48 have been 
assigned the revised stowage provision 25. Furthermore, no listings in 
the current HMR are assigned stowage provision 50 therefore we are 
deleting it and all references to it. The change to stowage provision 
128 is proposed to account for a citation change in the newest edition 
of the IMDG Code.
    In this NPRM PHMSA is also proposing to revise explosive stowage 
provision 26E and delete explosive stowage provisions 7E, 8E, and 20E 
from the table in paragraph (c)(2). Deleted explosive stowage provision 
7E previously read ``Stowage category ``04'' for projectiles or 
cartridges for guns, cannons or mortars; Stowage category ``08'' for 
other types.'' Deleted explosive stowage provision 8E previously read 
``When under deck, special stowage is required.'' Deleted explosive 
stowage provision 20E previously read ``Stowage category ``03'' for 
projectiles or cartridges for guns, cannons or mortars; Stowage 
category ``07'' for other types; magazines must be of steel 
construction that prevents leakage.'' Changes to explosive stowage 
provisions 7E, 8E, and 20E are necessary to account for revisions to 
the stowage category definitions proposed in Sec.  172.101(k). 
Additionally, as a result of the removal of stowage provisions 10 and 
13 from Sec.  172.101(k), PHMSA proposes to revise explosive stowage 
provision 26E in Sec.  176.84. Please see section 172.101 for explosive 
stowage codes associated with HMT entries previously assigned these 
explosive stowage provisions and a list of entries these provisions 
have been removed from.

Section 176.116

    Section 176.116 prescribes the general stowage conditions for Class 
1 explosive materials. Paragraph (a) of this section prescribes 
explosive stowage requirements, which take into account heat and 
sources of ignition. Paragraph (f) of this section prescribes 
explosives stowage requirements for under deck storage. In this NPRM 
PHMSA is proposing to revise paragraph (a) to clarify the general 
stowage conditions for Class 1 materials on board vessels and delete 
and reserve paragraph (f).
    PHMSA proposes to revise paragraph (a)(1) to require explosive 
materials to be stowed in a cool part of the ship, to be kept as cool 
as practicable while on board, and to be stowed as far away as 
practicable from any potential source of heat or ignition. This change 
is proposed due to the inclusion of a definition for ``potential source 
of heat or ignition'' in Sec.  176.2. A new paragraph (a)(2) is 
proposed requiring Class 1 materials to be stowed away from the side of 
a ship's side at a distance at least equal to one eighth of the beam of 
the vessel or 2.4 m (8 feet), whichever is less.
    This minimum distance for explosive shipment stowage from the 
ship's side is proposed to harmonize with a recent change in the IMDG 
Code and provides an increased level of safety by ensuring explosive 
shipments are not stowed adjacent to the ships internal structure.
    Paragraph (f) previously indicated general stowage provisions for 
HMT explosive entries stowed under deck and assigned stowage category 
09 or 10. The proposed removal of stowage category 09 and 10 make these 
provisions no longer applicable.

Section 176.128

    Section 176.128 defines the varying levels of containment for 
explosives identified as magazine stowage types ``A'', ``C,'' and 
``Special Stowage.'' The IMO has determined that a distinction between 
closed cargo transport units and magazines is no longer necessary. 
PHMSA concurs with the IMO on this issue and, thus, in this NPRM, 
proposes to delete Sec.  176.128 and reserve it for future use. With 
the addition of a definition for ``closed cargo transport

[[Page 49199]]

unit for Class 1,'' and the requirement for all explosive shipments to 
be stored at a distance at least equal to one eighth of the beam of the 
vessel or 2.4 m (8 feet), whichever is less, specific requirements for 
type A, C, and special magazine stowage are now unnecessary. Note that 
portable magazines remain authorized by Sec.  176.137 and the 
definition of ``closed cargo transport unit for Class 1.''

Section 176.130

    Section 176.130 prescribes requirements for magazine stowage type 
A. The IMO determined that a distinction between closed cargo transport 
units and magazines is no longer necessary. PHMSA concurs with the IMO 
on this issue and thus in this NPRM proposes to delete Sec.  176.130 
and reserve it for future use. In general, a magazine is equivalent to 
a closed cargo transport unit with a wooden floor. Properly packaged 
and transported packages in a closed cargo transport unit will 
adequately address safety concerns presented by commodities previously 
required to be transported in magazine stowage type A.

Section 176.133

    Section 176.133 prescribes requirements for magazine stowage type 
C. The IMO has determined that all explosive shipments must be stored 
at a distance at least equal to one eighth of the beam of the vessel or 
2.4 m (8 feet), whichever is less, thus making the provisions for 
magazine stowage type C unnecessary. PHMSA concurs with the IMO on this 
issue and thus in this NPRM proposes to delete Sec.  176.133 and 
reserve it for future use.

Section 176.134

    Section 176.134 prescribes requirements for vehicles carrying Class 
1 materials requiring magazine stowage. The removal of magazine stowage 
definitions and provisions make this section unnecessary. Therefore, in 
this NPRM PHMSA proposes to delete this section and reserve it for 
future use.

Section 176.136

    Section 176.136 prescribes requirements for special stowage of 
Class 1 materials. Changes to vessel stowage location codes in Sec.  
172.101(k) and the assignment of vessel stowage codes requiring on deck 
stowage for entries previously authorized special stowage make this 
section unnecessary. Therefore, in this NPRM PHMSA proposes to delete 
this section and reserve it for future use.

Section 176.138

    Section 176.138 prescribes general requirements for on deck 
stowage. Paragraph (b) provides general requirements for on deck 
stowage of explosives. In this NPRM PHMSA proposes to revise this 
section to require explosives to not be stowed within 6 m (20 feet) of 
the newly defined term ``any potential sources of heat or ignition.'' 
This change is proposed to incorporate a newly defined term in Sec.  
176.2.

Section 176.144

    Section 176.144 prescribes segregation requirements for Class 1 
materials transported by vessel. Paragraph (d) allows materials 
requiring ordinary stowage (non-magazine stowage) to be stowed in the 
same magazine as materials requiring magazine stowage. In this NPRM 
PHMSA proposes to revise paragraph (d) to state that if part of a 
shipment requires non-metallic lining of closed cargo transport units, 
Class 1 materials requiring ordinary stowage (stowage not requiring 
non-metallic lining of closed cargo transport units) may be stowed in 
the same closed cargo transport unit provided there are no exposed 
parts of any ferrous metal or aluminum alloy, unless separated by a 
partition. The removal of sections and requirements for magazine 
stowage necessitates a change in this section.

Section 176.146

    Section 176.146 prescribes segregation requirements for Class 1 
materials and non-hazardous goods transported by vessel. Paragraph (a) 
currently states that Class 1 material need not be segregated from non-
hazardous materials except as provided in paragraphs (b) and (c). 
Paragraph (b) then goes on to state that certain cargo (mail, baggage, 
and personal effects) may not be stowed in the same compartment as, or 
in compartments immediately above or below, Class 1 (explosive) 
materials other than those in compatibility group S. Paragraph (c) 
states that where Class 1 (explosive) materials are stowed against an 
intervening bulkhead, any mail on the other side of the bulkhead must 
be stowed away from it.
    In this NPRM, PHMSA proposes to revise paragraphs (a) and (b) and 
delete and reserve paragraph (c). Specifically, PHMSA proposes to 
revise paragraph (a) to remove a reference to the removed paragraph 
(c). PHMSA proposes to revise paragraph (b) to read ``readily 
combustible materials may not be stowed in the same compartment or hold 
as Class 1 (explosive) materials other than those in compatibility 
group S.'' This change incorporates the adoption by IMO of the defined 
term ``readily combustible material'' in 176.2. In this NPRM, PHMSA 
proposes removing and reserving paragraph (c) as the vast majority of 
mail is now sent by air and not vessel. A specific requirement for 
stowage of mail away from the intervening bulkhead between it and Class 
1 materials is deemed unnecessary.

Section 176.170

    Section 176.170 prescribes requirements for shipments of Class 1 
materials in freight containers by vessel. Paragraph (a) states that 
when Class 1 materials are stowed in a freight container, the freight 
container, for the purposes of this subpart, may be regarded as a 
magazine but not as a separate compartment. Paragraph (c) states that 
freight containers used to transport Class 1 (explosive) materials for 
which magazine stowage type A is required must have a floor consisting 
of tightly fitted wooden boards, plywood or equivalent non-metallic 
material, and a non-metallic lining.
    In this NPRM, PHMSA proposes to amend paragraph (a) and delete and 
reserve paragraph (c). Paragraph (a) would be revised to state that 
when Class 1 materials are stowed in a freight container, the freight 
container, for the purposes of this Subpart, may be regarded as a 
closed transport unit for Class 1 or a magazine but not a separate 
compartment. This change is being made to incorporate the proposed 
definition of ``closed cargo transport unit for Class 1'' and the 
removal of magazine stowage A, C, and Special Stowage. Paragraph (c) 
references freight containers used to transport Class 1 (explosive) 
materials for which magazine stowage type A is required. The removal of 
a definition for and requirements for magazine stowage type A make this 
paragraph unnecessary.

Section 176.200

    Section 176.200 prescribes general stowage requirements for Class 2 
materials transported by vessel. Paragraph (c) of this section 
prescribes the orientation and outer packaging requirements for 
cylinders transported by vessel.
    In this NPRM, PHMSA proposes revisions to paragraph (c) to clarify 
that cylinders offered for transport by vessel in a vertical position 
must be stowed in either a block and cribbed or boxed-in with suitable 
sound lumber. PHMSA also proposes to replace the word movement with 
shifting in the requirement for the crib or box bracing

[[Page 49200]]

to prevent any movement. These revisions are to harmonize with vessel 
transportation requirements incorporated in the IMDG Code and clarify 
that cylinders stored in a vertical position must be adequately blocked 
and braced using sound lumber.

Section 176.210

    Section 176.210 prescribes on deck stowage requirements for 
cylinders transported by vessel. This section currently requires 
cylinders of Class 2 materials being transported by vessel to be 
protected from radiant heat, including the direct rays of the sun, by 
structural erections or awnings.
    In this NPRM PHMSA proposes to revise this section by replacing 
``protected from radiant heat, including the direct rays of the sun, by 
structural erections or awnings'' with the newly defined term 
``protected from sources of heat.''

Section 176.230

    Section 176.230 prescribes stowage requirements for Division 2.1 
materials transported by vessel. Currently the HMR requires Division 
2.1 materials transported in Specification 106A or 110A multi-unit car 
tanks must be stowed on deck only, and must be shaded from radiant 
heat.
    In this NPRM, PHMSA proposes to replace the phrase ``shaded from 
radiant heat'' with the newly defined ``protected from sources of 
heat.''

Section 176.305

    Section 176.305 prescribes stowage requirements for Class 3 
materials transported by vessel. Paragraph (a) states that Class 3 
flammable or combustible liquids must be kept as cool as reasonably 
practicable and be stowed away from all sources of heat and ignition.
    In this NPRM, PHMSA proposes to revise paragraph (a) to read ``a 
Class 3 (flammable) or combustible liquid must be kept as cool as 
reasonably practicable, protected from sources of heat, and away from 
potential sources of ignition.'' These changes incorporate the proposed 
definitions of ``protected from sources of heat'' and ``potential or 
possible sources of ignition.''

Section 176.400

    Section 176.400 prescribes stowage requirements for Division 1.5, 
Class 4 (flammable solids) and Class 5 materials transported by vessel. 
Paragraph (a) requires Class 4 (flammable solid) material and Division 
5.2 (organic peroxide) materials to be kept as cool as reasonably 
practicable and be stowed away from all sources of heat and ignition.
    In this NPRM, PHMSA proposes to revise paragraph (a) to read 
``Class 4 (flammable solid) material and Division 5.2 (organic 
peroxide) material must be kept as cool as reasonably practicable, 
protected from sources of heat, and away from potential sources of 
ignition.'' These changes incorporate the proposed definitions of 
``protected from sources of heat'' and ``potential or possible sources 
of ignition.''
    Paragraph (b) of this section requires Division 5.2 (organic 
peroxide) material to be stowed away from living quarters or access to 
them. Division 5.2 (organic peroxide) substances not requiring 
temperature control should be protected from radiant heat, which 
includes direct rays of the sun, and stowed in a cool, well-ventilated 
area.
    In this NPRM, PHMSA proposes to amend paragraph (b) to replace 
``should be protected from radiant heat, which includes direct rays of 
the sun, and stowed in a cool, well-ventilated area'' with ``must be 
protected from sources of heat, including radiant heat and strong 
sunlight, and must be stowed in a cool, well-ventilated area.'' These 
changes are being made to incorporate the proposed definitions of 
``protected from sources of heat'' harmonize with the IMDG Code, and to 
emphasize that protecting shipments of organic peroxides not requiring 
temperature control from sources of heat is a requirement and not 
optional.

Section 176.600

    Section 176.600 prescribes detailed requirements for Division 2.3 
(Poisonous Gas) and Division 6.1 (Poisonous) materials transported by 
vessel. Paragraph (d) of this section requires each package of Division 
2.3 (poisonous gas) material or Division 6.1 (poison) material that 
also bears a FLAMMABLE LIQUID or FLAMMABLE GAS label must be stowed in 
a mechanically ventilated space, kept as cool as reasonably 
practicable, and be stowed away from all sources of heat and ignition.
    In this NPRM, PHMSA proposes to revise paragraph (d) to replace 
``stowed away from all sources of heat and ignition'' with ``protected 
from sources of heat and stowed away from potential sources of 
ignition.'' These changes incorporate the proposed definitions of 
``protected from sources of heat'' and ``potential or possible sources 
of ignition.''

Section 176.907

    Section 176.907 is created to incorporate cargo transport 
requirements for shipments of UN2211, Polymeric Beads, Expandable 
evolving flammable vapor and UN3314, Plastics Molding Compound in 
dough, sheet or extruded rope form, evolving flammable vapor. Several 
cases of damage to cargo transport units were presented to the IMO with 
the root cause being identified as the release of flammable pentane gas 
during transportation of shipments UN2211 and UN3314. To address the 
concerns presented by off gassing of flammable vapors which lead to a 
rise in pressure that may damage cargo transport units, the IMO 
instituted measures to ensure an adequate exchange of air within the 
cargo transport unit is provided. PHMSA proposes to harmonize with 
recent changes to the IMDG as well as to address safety concerns 
presented by the off gassing of flammable vapors from shipments of 
UN2211 and UN3314 by requiring that when UN2211 or UN3314 are 
transported by vessel, the cargo transport unit must provide an 
adequate exchange of air. This adequate exchange of air may be 
accomplished by using a ventilated container, an open-top container, or 
a container in one door off operation. As an alternative to these 
methods of air exchange, shippers may transport these cargos under 
temperature control in refrigerated cargo transport units. Exceptions 
to the cargo transport unit providing an adequate exchange of air 
requirement are provided for shipments packed in hermetically sealed 
packagings, IBCs which conform to the packing group II performance 
level for liquid dangerous goods, and packagings or IBCs in which the 
total pressure in the package (i.e., the vapor pressure of the liquid 
plus the partial pressure of air or other inert gasses less 100 kPa (15 
psia)) with a filling temperature of 15 [deg]C (131 [deg]F) does not 
exceed two-thirds of the marked test pressure. Cargo transport units 
containing shipments of UN2211 or UN3314 must be marked with a warning 
mark including the words ``CAUTION- MAY CONTAIN FLAMMABLE VAPOR'' or 
``CAUTION- MAY CONTAIN FLAMMABLE VAPOUR'' with lettering not less than 
25 mm high. This mark must be affixed at each access point in a 
location where it will be easily seen by persons prior to opening or 
entering the cargo transport unit and must remain on the cargo 
transport unit until the cargo transport unit has been completely 
ventilated to remove any hazardous concentration of vapor or gas, the 
immediate vicinity of the cargo transport unit is clear of any source 
of ignition, and the goods have been unloaded.

[[Page 49201]]

Part 178

Section 178.512

    Section 178.512 prescribes the standards, packaging identification 
codes, and construction requirements for steel and aluminum boxes (4A 
and 4B boxes). To incorporate the authorization for use of 4N boxes 
(metal other than steel or aluminum), the title of the section would be 
revised to ``Standards for steel, aluminum or other metal boxes.'' 
Section 178.512 is also revised to include the authorized packaging 
identification code, 4N, for other metal boxes, and expand the 
construction requirements of the section to include these packagings. 
Subsequent changes will be made throughout the section to address the 
inclusion of 4N other metal boxes.

Section 178.603

    Section 178.603 prescribes the drop test requirements for non-bulk 
packagings in the HMR. Section 178.603 provides that a drop test must 
be conducted for the qualification of all packaging design types, and 
further provides that exceptions for the number of steel and aluminum 
packaging samples used for conducting the drop test are subject to the 
approval of the Associate Administrator. Currently, paragraph (a) of 
this section contains a table that outlines specific types of 
packagings and the corresponding number of samples that should be 
tested and the drop orientation of those samples. In this NPRM, PHMSA 
is proposing to revise this table by including ``other metal boxes'' to 
the listed packagings. To incorporate the authorization for use of 4N 
boxes (metal other than steel or aluminum), Sec.  178.603 is revised to 
require the drop test for other metal (4N) boxes, and authorize 
exceptions, subject to the approval of the Associate Administrator, for 
the number of samples used for conducting the drop test of these 
packagings.

Section 178.705

    Section 178.705 prescribes standards for metal IBCs. Paragraph 
(a)(3) indicates that IBC specifications 31A, 31B, and 31N are 
authorized for both liquids and solids. PHMSA is proposing to revise 
this sentence editorially by removing the authorization to package 
solids in specification 31 IBCs as the specification is only assigned 
to liquid substances. This editorial change is consistent with the 
Sec.  172.102 IBC Code Table revisions in paragraph (c)(4) and other 
IBC standards (e.g., Sec.  178.707(a)(5)) prescribed in subpart N of 
part 178.

Section 178.910

    Section 178.910 prescribes the marking requirements for 
specification Large Packaging design types. Paragraph (a)(1) of this 
describes the size specifications and format of the marking 
requirements. In this NPRM PHMSA is proposing to clarify these 
requirements by indicating that for large packages manufactured after 
January 1, 2014 the minimum marking size must be 12 mm in height.
    Furthermore, paragraph (b) of this section is now reserved. 
However, we are proposing to add a paragraph (b) indicating that for 
all Large Packages manufactured, repaired or remanufactured after 
January 1, 2015 the large package must be marked with the symbol 
applicable to a Large Package designed for stacking or not designed for 
stacking, as appropriate. This language will be accompanied by an 
example of such a mark.

Section 178.980

    Section 178.980 prescribes the procedures for conducting the 
stacking test for qualification of all Large Packaging design types. 
Paragraph (e)(1) describes the criterion a metal or rigid plastic Large 
Packaging must meet to be considered as successfully passing the 
stacking test. While paragraph (e) addresses metal or rigid plastic 
Large Packagings, the criterion that a fiberboard or wooden Large 
Packaging must meet to be considered as successfully passing the 
stacking test is omitted.
    Therefore, in this NPRM, we propose to correct this omission, by 
adding a new paragraph (e)(2) that addresses the criterion for 
fiberboard or wooden Large Packagings to pass the test and 
redesignating the following paragraphs accordingly.

Subpart R

    Currently, the HMR do not contain specifications for FBCs. In this 
NPRM, PHMSA is proposing to adopt the specification, construction, and 
testing requirements for FBCs. On February 2, 2010, PHMSA published a 
final rule in the Federal Register under Docket Number PHMSA-2006- 
25736 (HM-231) [75 FR 4699] entitled ``Hazardous Materials; 
Miscellaneous Packaging Amendments.'' In HM-231, specification and 
testing requirements were adopted for Large Packagings. The 
specification and testing requirements for FBCs proposed in this NPRM 
are modeled on the regulatory structure adopted for Large Packagings in 
HM-231. Thus, new subpart R of part 178 entitled ``Subpart R--Flexible 
Bulk Container Standards'' is proposed.

Section 178.1000

    PHMSA proposes to adopt new Sec.  178.1000 entitled ``Purpose and 
scope.'' This section prescribes the packaging designs to which Subpart 
R applies and the location in the HMR where terms used in the subpart 
are defined.

Section 178.1005

    In this NPRM, PHMSA proposes to add new Sec.  178.1005 entitled 
``Flexible Bulk Container Identification Code.'' This section provides 
the identification code (i.e. BK3) assigned to FBCs.

Section 178.1010

    In this NPRM, PHMSA proposes to add new Sec.  178.1010 entitled 
``Marking of Flexible Bulk Containers.'' This section prescribes the 
markings the manufacturer of an FBC must mark on a package to indicate 
the FBC meets the specification. The proposed marking requirements for 
FBCs are based on the current marking requirements for IBCs prescribed 
in Sec.  178.703.

Section 178.1015

    In this NPRM, PHMSA proposes to add new Sec.  178.1015 entitled 
``General Flexible Bulk Container Standards.'' This section prescribes 
the general packaging integrity requirements an FBC design must meet.

Section 178.1020

    In this NPRM, PHMSA proposes to add new Sec.  178.1020 entitled 
``Period of use for transportation of hazardous materials in Flexible 
Bulk Containers.'' This section prescribes the length of time an FBC 
may be used to package hazardous materials. Specifically, this section 
states that an FBC used to package hazardous materials may remain in 
service not to exceed two years from the date of manufacture.

Subpart S

    Currently, the HMR do not prescribe testing criteria for FBCs. In 
this NPRM, PHMSA is proposing to adopt testing protocol for FBCs. On 
February 2, 2010, PHMSA published a final rule in the Federal Register 
under Docket Number PHMSA-2006-25736 (HM-231) [75 FR 4699] entitled 
``Hazardous Materials; Miscellaneous Packaging Amendments.'' In HM-231, 
specification and testing requirements were adopted for Large 
Packagings. The test protocol proposed in this NPRM for FBCs is modeled 
on the regulatory structure adopted for Large Packagings in HM-231. 
Thus, new subpart S of part 178 entitled ``Subpart S--Testing of 
Flexible Bulk Container Standards'' is proposed.

[[Page 49202]]

Section 178.1030

    In this NPRM, PHMSA proposes to adopt Sec.  178.1030 entitled 
``Purpose and scope.'' This section prescribes the applicability to 
which the Subpart S tests apply.

Section 178.1035

    In this NPRM, PHMSA proposes to adopt Sec.  178.1035 entitled 
``General requirements.'' This section prescribes the general packaging 
requirements for FBCs and addresses the following topics: FBC-related 
definitions; defining responsibility for compliance with specification 
requirements; design qualification testing; periodic design testing; 
proof of compliance; and record retention.

Section 178.1040

    In this NPRM, PHMSA is proposing to adopt test preparation 
requirements for FBCs in new Sec.  178.1040 entitled ``Preparation of 
Flexible Bulk Containers for Testing.'' This section specifies the 
general test preparation requirements applicable to all tests an FBC is 
required to successfully pass.

Section 178.1045

    In this NPRM, PHMSA is proposing to adopt requirements for drop 
tests conducted on FBCs. A drop test is used to measure a packaging's 
ability to withstand falls from specific heights and is used to 
determine if a package is suitable to transport hazardous materials. 
Thus, PHMSA proposes to add a new Sec.  178.1045 entitled ``Drop 
test.'' This section prescribes the preparation of test samples, test 
methods authorized, drop heights, and criteria for passing the drop 
test.

Section 178.1050

    In this NPRM, PHMSA is proposing to adopt requirements for top lift 
tests conducted on FBCs. A top lift test measures a package's ability 
to be moved mechanically by lifting the package by its top end and is 
used to determine if a package is suitable to transport hazardous 
materials. Thus, PHMSA proposes to add new Sec.  178.1050 entitled 
``Top lift test.'' This section prescribes requirements for the 
preparation of test samples, test methods authorized, and criteria for 
passing the top lift test.

Section 178.1055

    In this NPRM, PHMSA is proposing to adopt requirements for stacking 
tests conducted on FBCs. A stacking test is used to measure a 
packaging's ability to withstand other packages placed on top of it and 
is used to determine if a package is suitable to transport hazardous 
materials. Thus, PHMSA proposes to add new Sec.  178.1055 entitled 
``Stacking test.'' This section prescribes requirements for the 
preparation of test samples, test methods authorized, and criteria for 
passing the stacking test.

Section 178.1060

    In this NPRM, PHMSA is proposing to adopt requirements for topple 
tests conducted on FBCs. A topple test is used to measure a packaging's 
ability to withstand tipping of the package and is used to determine if 
a package is suitable to transport hazardous materials. Thus, PHMSA 
proposes to add new Sec.  178.1060 entitled ``Topple test.'' This 
section prescribes the preparation of test samples, test methods 
authorized, topple height, and criteria for passing the topple test.

Section 178.1065

    In this NPRM, PHMSA is proposing to adopt requirements for righting 
tests conducted on FBCs. A righting test is used to measure a 
packaging's ability to withstand lifting from a lying position at a 
given rate of speed and is used to determine if a package is suitable 
to transport hazardous materials. Thus, PHMSA proposes to add new Sec.  
178.1065 entitled ``Righting test.'' This section prescribes the 
preparation of test samples, test methods authorized, and criteria for 
passing the righting test.

Section 178.1070

    In this NPRM, PHMSA is proposing to adopt requirements for tear 
tests conducted on FBCs. A tear test is used to measure a packaging's 
ability to withstand shearing and tearing that may be encountered 
during transportation, such as loading and unloading, and is used to 
determine if a package is suitable to transport hazardous materials. 
Thus, PHMSA proposes to add new Sec.  178.1070 entitled ``Tear test.'' 
This section prescribes the preparation of test samples, test methods 
authorized, and criteria for passing the tear test.

VI. Regulatory Analyses and Notices

A. Statutory/Legal Authority for This Rulemaking

    This proposed rule is published under the following statutory 
authorities:
    1. 49 U.S.C. 5103(b) 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 amends 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 them with the biennial updates 
of the UN Model Regulations, the IMDG Code and the ICAO Technical 
Instructions.
    Harmonization serves to facilitate international commerce; at the 
same time, harmonization promotes the safety of people, property, and 
the environment by reducing the potential for confusion and 
misunderstanding that could result if shippers and transporters were 
required to comply with two or more conflicting sets of regulatory 
requirements. While the intent of this rulemaking is to align the HMR 
with international standards, we review and consider each amendment on 
its own merit based on its overall impact on transportation safety and 
the economic implications associated with its adoption into the HMR. 
Our goal is to harmonize without sacrificing the current HMR level of 
safety and without imposing undue burdens on the regulated community. 
Thus, as explained in the corresponding sections above, we are not 
proposing harmonization with certain specific provisions of the UN 
Model Regulations, the IMDG Code, and the ICAO Technical Instructions. 
Moreover, we are maintaining a number of current exceptions for 
domestic transportation that should minimize the compliance burden on 
the regulated community. Additionally, the following external agencies 
were consulted in the development of this rule: U.S. Coast Guard, U.S. 
Department of Agriculture (USDA), U.S. Department of Energy, U.S. 
Department of Interior, U.S. Department of Justice.
    2. 49 U.S.C. 5120(b) authorizes the Secretary of Transportation 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 17th Revised Edition of the UN Model Regulations, 
Amendment 36-12 to the IMDG Code, and the 2013-2014 ICAO Technical 
Instructions, which become effective January 1, 2013. The large volume 
of hazardous materials transported in international commerce

[[Page 49203]]

warrants the harmonization of domestic and international requirements 
to the greatest extent possible.

B. Executive Orders 12866 and 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). Additionally, E.O. 13563 (``Improving Regulation and 
Regulatory Review'') supplements and reaffirms E.O. 12866, stressing 
that, to the extent permitted by law, an agency rulemaking action must 
be based on benefits that justify its costs, impose the least burden, 
consider cumulative burdens, maximize benefits, use performance 
objectives, and assess available alternatives.
    Benefits to Harmonization. In this NPRM, PHMSA is proposing to 
incorporate by reference the most recent versions of various 
international hazardous materials standards, including the 2013-2014 
ICAO Technical Instructions, Amendment 36-12 to the IMDG Code, and the 
17th Revised Edition of the UN Model Regulations. Additionally, PHMSA 
is proposing to update its incorporation by reference of the Canadian 
Transportation of Dangerous Goods Regulations to include Amendment 8 
(SOR/2011-239) November 9, 2011; Amendment 9 (SOR/2011-60) March 16, 
2011; and Amendment 10 (SOR/2011-210) October 12, 2011. Lastly, PHMSA 
is proposing to adopt updated International Standards Organization 
(ISO) standards.
    The primary benefit of harmonizing the U.S. Hazardous Materials 
Regulations (HMR) with the international hazardous materials standards 
noted previously is that it will reduce the regulatory compliance costs 
faced by U.S. companies. Without harmonization, these companies will be 
forced to comply with dual systems of regulations, and as a result will 
incur higher compliance costs than would be encountered under a single 
regulatory scheme. The benefit of harmonization attributable to this 
proposed rulemaking is the difference in regulatory compliance costs 
faced by companies operating under a single regulatory framework 
instead of multiple regulatory frameworks.
    If the U.S. regulations are not harmonized with the international 
standards mentioned above, we estimate that it will cost U.S. companies 
an additional $62 million per year to comply with both the HMR and the 
international standards. Harmonizing the HMR with the international 
standards, however, will avert these $62 million in additional costs, 
and these averted costs are therefore considered the primary benefit 
attributable to this rulemaking.
    The $62 million estimate is based on the assumption that in the 
absence of harmonization both exporters and importers would have to 
adhere to two separate hazard communication systems, one used for the 
transportation of materials within the United States and one used for 
the transportation of materials outside the United States. Exporters 
would directly incur four different cost elements and would have to pay 
for (1) Dual labels and safety data sheets, (2) additional training, 
(3) additional management activities, and (4) additional packaging 
costs. Foreign producers who ship products to the United States would 
also incur these four cost elements, and we assume that the foreign 
producers would pass half of those incurred costs on to U.S. consumers 
in the form of higher prices.
    To develop the $62 million estimate, we estimated the average 
hazard communication cost per dollar of hazardous materials produced in 
the United States and then multiplied that cost figure by an estimate 
of the value of U.S. imports and exports of hazardous materials. In 
other words, in the absence of harmonization, we assume that companies 
involved with U.S. foreign trade would have to pay for additional 
hazard communication requirements for international movements; these 
companies would have to comply with the HMR communication requirements 
during domestic legs of the movement and with international standards 
during legs of the movement outside of the United States.
    A proxy for hazard communication costs was obtained from a recent 
OSHA study looking at the costs for industry to comply with the revised 
Hazard Communication Standard.\3\ The study estimated the total 
compliance cost to be $201 million per year based on four cost 
elements: revisions to labels and safety data sheets, additional 
training, additional management activities, and printing of color 
packaging. The first three cost elements are relevant for our purposes 
and totaled $177 million.
---------------------------------------------------------------------------

    \3\ http://www.osha.gov/dsg/hazcom/hazcom-faq.html.
---------------------------------------------------------------------------

    To put the $177 million hazard communication cost estimate on a per 
unit basis, we divided the $177 million by an estimate of the total 
value of hazardous materials produced in the United States in 2010. The 
total value of hazardous materials produced in the United States was 
estimated to be $151 billion. To derive this $151 billion estimate, we 
summed relevant product values reported in the Census Bureau's Annual 
Survey of Manufactures: Value of Product Shipments, and then multiplied 
the result by 12.4 percent--the percentage of shipment values reported 
to be hazardous products (this parameter was obtained from Table 10 in 
the Census Bureau's 2007 Commodity Flow Survey for Hazardous 
Materials). The resulting hazard communication cost per dollar of 
hazardous materials output was estimated to be $0.001 (or $177 million 
/ $151 billion).
    We were not able to identify any comprehensive source on hazardous 
materials imports and exports and therefore developed estimates for 
these figures using quarterly trade data from the Bureau of Economic 
Analysis\4\ and data on the transportation of hazardous materials from 
the Census Bureau's 2007 Commodity Flow Survey. The quarterly trade 
data on the value of imports and exports--for fuels and lubricants, 
chemicals, and medicinal/dental/pharmaceutical products--were summed to 
produce a single annual trade value for 2010 for industries that 
produce hazardous materials. Before aggregating the import and export 
values, we reduced the import values by half to take into account the 
assumption mentioned previously that foreign producers would be able to 
pass on only half of the additional hazard communication costs to U.S. 
consumers. Total annual trade for industries that produce hazardous 
materials was computed to be just over $498 billion in 2010.
---------------------------------------------------------------------------

    \4\ http://www.bea.gov/international/detailed_trade_data.htm.
---------------------------------------------------------------------------

    We then multiplied this $498 billion trade figure by 12.4 percent, 
the percentage of output in these industries reported to be hazardous 
products; this parameter was obtained from Table 10 in the 2007 
Commodity Flow Survey for Hazardous Materials. The resulting estimate 
indicates that approximately $62 billion worth of hazardous materials 
were involved in international trade with the United States in 2010.
    Multiplying the hazard communication cost per dollar of hazardous 
material output ($0.001) by the value of hazardous materials involved 
in international trade ($62

[[Page 49204]]

billion) results in a hazard communication cost estimate of 
approximately $62 million per year that companies would have to pay to 
comply with different regulatory requirements applicable to 
international movements. Harmonizing the HMR with international 
standards would make these $62 million in hazard communications costs 
unnecessary, and therefore is the main benefit attributable to this 
rulemaking.
    Cost of Harmonization. The potential costs of this rulemaking 
include private sector compliance costs and any costs that can be 
attributed to a possible reduction in public safety as a result of 
harmonizing the HMR with international standards. We expect that both 
of these costs will be negligible. Preliminary estimates suggest that 
private sector compliance costs associated with complying with the 
different amendments in the NPRM will be minimal. In terms of costs due 
to any reduction in public safety as a result of harmonizing the HMR 
with international standards, PHMSA believes that none of the proposed 
revisions to the HMR have material safety impacts. We therefore assume 
that the gross social costs of this NPRM are effectively zero.
    Net Benefit. Based on the discussions of benefits and costs 
provided above the estimated net benefit associated with the 
international harmonization NPRM (2137-AE87) is nearly $62 million.

C. Executive Order 13132

    This proposed rule has been analyzed in accordance with the 
principles and criteria contained in Executive Order 13132 
(``Federalism''). This proposed rule 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 hazardous material transportation law, 49 U.S.C. 5101-
5128, 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, 2013. If the changes in 
this proposed rule are not adopted in the HMR, U.S. companies, 
including numerous small entities competing in foreign markets, would 
be at an economic disadvantage. These companies would be forced to 
comply with a dual system of regulations. The changes in this proposed 
rulemaking are intended to avoid this result. Federal hazardous 
materials transportation 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 the effective 
date of Federal preemption be 90 days from publication of a final rule 
in this matter.

D. Executive Order 13175

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

E. 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 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. This proposed rule 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 discussed above, under 
Executive Order 12866, the majority of amendments in this proposed rule 
should result in 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, we certify that these amendments will not, if 
promulgated, have a significant economic impact on a substantial number 
of 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.

F. Paperwork Reduction Act

    PHMSA currently has approved information collections under Office 
of Management and Budget (OMB) Control Number 2137-0018, ``Inspection 
and Testing of Portable Tanks and Intermediate Bulk Containers,'' and 
OMB Control Number 2137-0572, ``Testing Requirements for Non-Bulk 
Packages.'' This NPRM may result in an increase in the annual burden 
and costs of both OMB Control Numbers due to the proposed amendments to 
allow the use of metals other than steel or aluminum for drums and 
boxes as well as the proposed new Flexible Bulk Container package 
authorization, which will require package manufacturers to document and 
maintain package test results, should they elect to manufacture 
Flexible Bulk Containers.
    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), title 5, 
Code

[[Page 49205]]

of Federal Regulations requires that PHMSA provide interested members 
of the public and affected agencies an opportunity to comment on 
information and recordkeeping requests.
    This notice identifies revised information collection requests that 
PHMSA will submit to OMB for approval based on the requirements in this 
proposed rule. PHMSA has developed burden estimates to reflect changes 
in this proposed rule, and estimates the information collection and 
recordkeeping burden as proposed in this rule to be as follows:

------------------------------------------------------------------------
 
------------------------------------------------------------------------
OMB Control No.............................................    2137-0018
  Annual Increase in Number of Respondents.................           25
  Annual Increase in Annual Number of Responses............           50
  Annual Increase in Annual Burden Hours...................          200
  Annual Increase in Annual Burden Costs...................       $5,000
 
OMB Control No.............................................    2137-0572
  Annual Increase in Number of Respondents.................          100
  Annual Increase in Annual Number of Responses............          300
  Annual Increase in Annual Burden Hours...................          600
  Annual Increase in Annual Burden Costs...................      $15,000
------------------------------------------------------------------------

    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-
6974. Requests for a copy of this information collection should be 
directed to Steven Andrews or T. Glenn Foster, Standards and Rulemaking 
Division (PHH-10), Pipeline and Hazardous Materials Safety 
Administration, 1200 New Jersey Avenue SE., Washington, DC 20590-0001, 
Telephone (202) 366-8553. If these proposed requirements are adopted in 
a final rule, PHMSA will submit the revised information collection and 
recordkeeping requirements to OMB for approval.

G. 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.

H. Unfunded Mandates Reform Act

    This proposed rule does not impose unfunded mandates under the 
Unfunded Mandates Reform Act of 1995. It does not result in costs of 
$141.3 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.

I. Environmental Assessment

    The National Environmental Policy Act, 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 
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. 40 CFR 1508.9(b).
Description of Action
    Docket No. PHMSA-2012-0027 (HM-215L), NPRM. The transportation of 
hazardous materials in commerce is subject to the HMR, issued under 
authority of Federal hazardous materials transportation law, codified 
at 49 U.S.C. 5001 et seq. To facilitate the safe and efficient 
transportation of hazardous materials in international commerce, the 
HMR provides that both domestic and international shipments of 
hazardous materials may be offered for transportation and transported 
under provisions of the international regulations.
Purpose and Need
    In this NPRM, PHMSA is proposing to amend the Hazardous Materials 
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. These revisions are necessary to harmonize and align the 
HMR with recent amendments adopted in the UN Model Regulations, IMDG 
Code, and the ICAO Technical Instructions. The amendments proposed in 
this notice are intended to facilitate the safe and efficient 
transportation of hazardous materials in international commerce, 
provide clarity designed to encourage and increase regulatory 
compliance, and improve the efficacy of emergency response in the event 
a hazardous materials incident occurs.
Alternatives
    In developing this proposed rule, we considered three alternatives:
    (1) Do nothing.
    (2) Adopt the international standards in their entirety.
    (3) Adopt most of the international standards, with certain 
modifications based on safety or economic considerations.
    Alternative 1:
    Because our goal is to facilitate uniformity, compliance, commerce 
and safety in the transportation of hazardous materials, we rejected 
this alternative.
    Alternative 2:
    By adopting the international standards in their entirety, PHMSA 
could potentially adopt provisions that, in our view, do not provide an 
adequate level of transportation safety and environmental safety and 
protection. Further, because we provide for domestic exceptions and 
extended compliance periods to minimize the potential economic impact 
of any revisions on the regulated community, this alternative was also 
rejected.
    Alternative 3:
    Consistency between U.S. and international regulations helps to 
assure the safety of international hazardous materials transportation 
and the environment through better understanding of the regulations, an 
increased level of compliance, the smooth flow of hazardous materials 
from their points of origin to their points of destination, and 
effective emergency response in the event of a hazardous materials 
incident. Under Alternative 3, we would harmonize the HMR with 
international standards to the extent consistent with U.S. safety, 
economic, and environmental protection goals.
    Alternative 3 is the only alternative that addresses, in all 
respects, the purpose of this regulatory action, which is to facilitate 
the safe and efficient transportation of hazardous materials in 
international commerce and the protection of the environment. These 
actions will provide the greatest possible harmonization with

[[Page 49206]]

international requirements without posing an undue increased cost 
burden on the regulated community. For these reasons, alternative 3 is 
our recommended alternative.
Analysis of Environmental Impacts
    Hazardous materials are transported by aircraft, vessel, rail, and 
highway. The potential for environmental damage or contamination exists 
when packages of hazardous materials are involved in accidents or en 
route incidents resulting from cargo shifts, valve failures, package 
failures, or loading, unloading, or handling problems. The ecosystems 
that could be affected by a release include air, water, soil, and 
ecological resources (for example, wildlife habitats). The adverse 
environmental impacts associated with releases of most hazardous 
materials are short-term impacts that can be greatly reduced or 
eliminated through prompt clean-up of the accident scene. Most 
hazardous materials are not transported in quantities sufficient to 
cause significant, long-term environmental damage if they are released.
    The hazardous material regulatory system is a risk-management 
system that is prevention-oriented and focused on identifying hazards 
and reducing the probability and quantity of a hazardous material 
release. Amending the HMR to maintain alignment with international 
standards enhances the safe transportation of hazardous materials in 
domestic and international commerce. When considering the adoption of 
international standards under the HMR, we review and consider each 
amendment on its own merit and assess the likely impact on 
transportation safety and the environment. It is our preliminary 
conclusion that the proposals in this notice will not have either a 
substantial positive or adverse effect on the environment. 
Consequently, PHMSA welcomes public comment on the matter.
    In this NPRM, PHMSA is proposing the following noteworthy 
amendments to the HMR:
    Chemicals under pressure. Manufacturers in the United Kingdom, the 
United States, Australia, Canada, and other countries are supplying 
pressurized products contained and transported in gas cylinders. The 
products are liquids or solids such as adhesives, coatings and cleaners 
combined with a gas or gas mixtures in pressure receptacles under 
sufficient pressure to expel the contents. These mixtures are typically 
expelled from the pressurized cylinders as foams, streams or thick 
sprays. Currently the HMR does not comprehensively address chemicals 
under pressure. Because of the substantial packaging integrity inherent 
in pressure vessel designs, PHMSA believes the proposed chemical under 
pressure amendments in this rule will result in a positive 
environmental impact.
    Flexible Bulk Containers (FBCs). Incorporate a new packaging 
definition, operational controls, performance-oriented standards, and 
testing requirements for Flexible Bulk Containers (FBCs). FBCs are 
flexible bulk packages with a capacity over the currently authorized 
maximum volumetric capacity for flexible IBCs, but not exceeding 15 
cubic meters. FBCs provide shippers the opportunity to utilize a 
reusable flexible packaging for bulk shipments of certain authorized 
low-hazard commodities, all of which are currently authorized in non-
specification bulk bins. Because of the inherent integrity of a 
specification packaging design when compared to a non-specification 
packaging design, PHMSA believes the amendments in this proposal 
authorizing the construction and use of FBCs will result in a net 
positive environmental impact.
    Packaging Authorizations. Part 173 of the HMR prescribes the 
general requirements for shipment preparation and packaging selection 
for hazardous materials. Consistent with amendments adopted in the 
various international standards, we are proposing to amend multiple 
part 173 packaging sections by authorizing additional packaging 
specifications used to package hazardous materials. These proposed 
amendments include, but are not limited to, the authorization to use 
wood as a material of package construction for certain explosives, the 
authorization to use metals other than steel or aluminum for boxes and 
drums for certain hazardous materials, and the incorporation of 
authorizations and specifications of FBCs. Because of the substantial 
integrity in the newly authorized packaging specifications, PHMSA 
believes the amendments in this proposal will result in a positive 
environmental impact. Higher integrity packaging designs can and do 
prevent the unintentional release of hazardous materials when 
transported in commerce.
    Vessel Stowage Requirements. The requirements for vessel stowage 
are described and specified in Sec.  172.101(k) and HMT entries are 
assigned appropriate vessel stowage codes and stowage special 
provisions in column 10 of the HMT. We propose to clarify these 
instructions by revising the vessel stowage location requirements for 
explosives and reducing the number of explosive stowage categories from 
15 to 5 in column 10A of the HMT. Specifically, explosive stowage 
categories 6 through 15 will be eliminated, and stowage categories 1 
through 5 will be retained and modified. We are also proposing 
modifications to the vessel stowage provisions indicated in column 10B 
of the HMT. In order to harmonize with the IMDG Code, PHMSA proposes to 
incorporate the addition of a new definition for protected from sources 
of heat and potential or possible sources of ignition (see Section 
176.2 of this NPRM for definitions), and subsequently revise and delete 
various vessel stowage provisions.
    Because the amendments proposed in this notice reducing and 
consolidating the number of vessel stowage codes for explosives result 
in greater clarity of the HMR and reduce the potential of incidents 
occurring, PHMSA believes they will have a positive impact on the 
environment.
Conclusion
    In this NPRM, PHMSA proposes to amend the HMR in response to 
revisions adopted in the various international standards. Through this 
integrated and cooperative approach, we believe we can be most 
successful in reducing incidents, enhancing public safety, and 
protecting the environment. The proposed amendments are intended to 
update, clarify, or provide relief from certain existing regulatory 
requirements and to provide greater flexibility in packaging selection 
suitable for the transportation of hazardous materials. PHMSA believes 
the net environmental impact of this rule will be positive. 
Additionally, we believe there will be little or no adverse 
environmental impacts associated with the amendments proposed in this 
rule. PHMSA solicits public comment on the conclusions made in this 
preliminary analysis.

K. Executive Order 13609 and International Trade Analysis

    Under E.O. 13609, 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 we have 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 E.O. 13609 and PHMSA's obligations under the Trade 
Agreement Act, as amended.

    (i) The material may be stowed ``on deck'' or ``under deck'' on a 
cargo vessel and on a passenger vessel carrying a number of passengers 
limited to not more than the larger of 25 passengers, or one passenger 
per each 3 m of overall vessel length; and
    (ii) ``On deck only'' on passenger vessels in which the number of 
passengers specified in paragraph (k)(2)(i) of this section is 
exceeded.
    (3) Stowage category ``C'' means the material must be stowed ``on 
deck only'' on a cargo vessel and on a passenger vessel.
    (4) Stowage category ``D'' means the material must be stowed ``on 
deck only'' on a cargo vessel and on a passenger vessel carrying a 
number of passengers limited to not more than the larger of 25 
passengers or one passenger per each 3 m of overall vessel length, but 
the material is prohibited on a passenger vessel in which the limiting 
number of passengers is exceeded.
    (5) Stowage category ``E'' means the material may be stowed ``on 
deck'' or ``under deck'' on a cargo vessel and on a passenger vessel 
carrying a number of passengers limited to not more than the larger of 
25 passengers, or one passenger per each 3 m of overall vessel length, 
but is prohibited from carriage on a passenger vessel in which the 
limiting number of passengers is exceeded.
    (6) Stowage category ``01'' means the material may be stowed ``on 
deck'' in closed cargo transport units or ``under deck'' on a cargo 
vessel (up to 12 passengers) and on a passenger vessel.
    (7) Stowage category ``02'' means the material may be stowed ``on 
deck'' in closed cargo transport units or ``under deck'' on a cargo 
vessel (up to 12 passengers) and ``on deck'' in closed cargo transport 
units or ``under deck'' in closed cargo transport units on a passenger 
vessel.
    (8) Stowage category ``03'' means the material may be stowed ``on 
deck'' in closed cargo transport units or ``under deck'' on a cargo 
vessel (up to 12 passengers) but the material is prohibited on a 
passenger vessel.
    (9) Stowage category ``04'' means the material may be stowed ``on 
deck'' in closed cargo transport units or ``under deck'' in closed 
cargo transports on a cargo vessel (up to 12 passengers) but the 
material is prohibited on a passenger vessel.
    (10) Stowage category ``05'' means the material may be stowed ``on 
deck'' in closed cargo transport units on a cargo vessel (up to 12 
passengers) but the material is prohibited on a passenger vessel.
* * * * *
    6. In Sec.  172.101, the Hazardous Materials Table is amended by 
removing the entries under ``[REMOVE]'', by adding the entries under 
``[ADD]'' and revising entries under ``[REVISE]'' in the appropriate 
alphabetical sequence to read as follows:

transportation of hazardous materials must conform to the requirements 
of its specification and regulations for the transportation of the 
particular commodity.
    (b) Initial use and reuse of Flexible Bulk Containers. A Flexible 
Bulk Container may be reused. Before a Flexible Bulk Container is 
filled and offered for transportation, the Flexible Bulk Container must 
be given an external visual inspection by the person filling the 
Flexible Bulk Container to ensure:
    (1) The Flexible Bulk Container is free from corrosion, 
contamination, cracks, cuts, or other damage that would render it 
unable to pass the prescribed design type test to which it is certified 
and marked; and
    (2) The Flexible Bulk Container is marked in accordance with 
requirements in Sec.  178.1010 of this subchapter. Required markings 
that are missing, damaged or difficult to read must be restored or 
returned to original condition.

hazardous materials is permitted for a period of time not to exceed two 
years from the date of manufacture of the Flexible Bulk Container.
    (c) During transportation--
    (1) No hazardous material may remain on the outside of the Flexible 
Bulk Container; and
    (2) Each Flexible Bulk Container must be securely fastened to or 
contained within the transport unit.
    (3) If restraints such as banding or straps are used, these straps 
must not be over-tightened to an extent that causes damage or 
deformation to the Flexible Bulk Container.
    (4) Flexible Bulk Containers must be transported in a conveyance 
with rigid sides and ends that extend at least two-thirds of the height 
of the Flexible Bulk Container.
    (5) Flexible Bulk Containers must not be stacked for highway or 
rail transportation.
    (6) Flexible Bulk Containers must not be transported in cargo 
transport units when offered for transportation by vessel.
    (7) Flexible Bulk Containers when transported by barge must be 
stowed in such a way that there are no void spaces between the Flexible 
Bulk Containers in the barge. If the Flexible Bulk Containers do not 
completely fill the barge, adequate measures must be taken to avoid 
shifting of cargo. The maximum permissible height of the stack of 
Flexible Bulk Containers must not exceed 3 high.
    (d) A Flexible Bulk Container used to transport hazardous materials 
may not exceed 15 cubic meters capacity.

PART 176--CARRIAGE BY VESSEL

    64. The authority citation for part 176 continues to read as 
follows:

    Authority: 49 U.S.C. 5101-5128; 49 CFR Sec.  1.53.

    65. In Sec.  176.2, the following definition for ``Closed cargo 
transport unit for Class 1 (explosive) materials'', ``Potential or 
possible sources of ignition'', and ``Protected from sources of heat'' 
are added in alphabetical order as follows:

Sec.  176.2  Definitions.

* * * * *
    Closed cargo transport unit for Class 1 (explosive) materials means 
a freight container or transport vehicle that fully encloses the 
contents by permanent structures and can be secured to the ship's 
structure and are, except for the carriage of division 1.4 explosives, 
structurally serviceable (see Sec.  176.172). Portable magazines 
conforming to Sec.  176.137 are also considered closed cargo transport 
units for Class 1. Small compartments such as deck houses and mast 
lockers are included. Cargo transport units with fabric sides or tops 
are not closed cargo transport units. The floor of any closed cargo 
transport unit must either be constructed of wood, close-boarded or so 
arranged that goods are stowed on sparred gratings, wooden pallets or 
dunnage.
* * * * *
    Potential or possible sources of ignition means, but is not limited 
to, open fires, machinery exhausts, galley uptakes, electrical outlets 
and electrical equipment including those on

[[Page 49270]]

refrigerated or heated cargo transport units unless they are of a type 
designed to operate in a hazardous environment.
* * * * *
    Protected from sources of heat means that packages and cargo 
transport units must be stowed at least 2.4 m from heated ship 
structures, where the surface temperature is liable to exceed 
131[emsp14][deg]F (55 [deg]C). Examples of heated structures are steam 
pipes, heating coils, top or side walls of heated fuel and cargo tanks, 
and bulkheads of machinery spaces. In addition, packages not loaded 
inside a cargo transport unit and stowed on deck must be shaded from 
direct sunlight. The surface of a cargo transport unit can heat rapidly 
when in direct sunlight in nearly windless conditions and the cargo may 
also become heated. Depending on the nature of the goods in the cargo 
transport unit, and the planned voyage, precautions must be taken to 
ensure that exposure to direct sunlight is reduced.
* * * * *
    66. In Sec.  176.63, paragraphs (b) and (e) are revised to read as 
follows:

Sec.  176.63  Stowage locations.

* * * * *
    (b) To qualify as ``on deck'' stowage, the location must be on the 
weather deck. If the location is in a house on the weather deck, the 
location must have a permanent structural opening to the atmosphere, 
such as a door, hatch, companionway or manhole, and must be vented to 
the atmosphere. The location may not have any structural opening to any 
living quarters, cargo, or other compartment unless the opening has 
means for being closed off and secured. Any deck house containing 
living quarters, a steering engine, a refrigerating unit, a 
refrigerated stowage box, or a heating unit may not be used unless that 
area is isolated from the cargo stowage area by a permanent, and tight, 
metallic bulkhead. Stowage in a shelter or 'tween deck is not 
considered to be ``on deck''. A barge that is vented to the atmosphere 
and is stowed on deck on a barge-carrying ship is considered to be ``on 
deck''. When an entry in Sec.  172.101 of this subchapter requires 
``on-deck'' stowage and is qualified by the requirement ``protected 
from sources of heat'', the stowage must be protected from the direct 
rays of the sun by means of structural erections or awnings except that 
such protection is not required for shipment in portable tanks.
* * * * *
    (e) Notwithstanding the stowage provisions given in the table in 
Sec.  172.101 of this subchapter, empty packages containing residue, 
including IBCs and large packages, may be stowed ``on deck'' or ``under 
deck'' in a mechanically ventilated cargo space. However, empty 
pressure receptacles containing residue that carry a label of class 2.3 
must be stowed ``on deck'' and waste aerosols must be stowed in 
accordance with the table in Sec.  172.101 of this subchapter.
* * * * *
    67. In Sec.  176.76, paragraph (a)(9) is revised to read as 
follows:

Sec.  176.76  Transport vehicles, freight containers, and portable 
tanks containing hazardous materials.

    (a) * * *
    (9) When packages are secured with banding or straps, these 
restraints must not be over-tightened to cause damage or deformation of 
the packages or the securing points (such as D-rings) within the 
freight container or transport vehicle;
* * * * *
    68. In Sec.  176.83 paragraphs (m)(2) and (m)(3) are revised to 
read as follows:

Sec.  176.83  Segregation.

* * * * *
    (m) * * *
    (2) Not all hazardous materials falling within a segregation group 
are listed by name in the regulations. These materials are shipped 
under ``n.o.s.'' entries. Although these ``n.o.s.'' entries are not 
listed themselves in the above groups, the person who offers a 
hazardous material for transportation must decide whether allocation 
under a segregation group is appropriate.
    (3) The segregation groups described above do not address materials 
that fall outside the classification criteria of the hazardous 
materials regulations, although it is recognized that some non-
hazardous materials have certain chemical properties similar to 
hazardous materials listed in the segregation groups. A person who 
offers a hazardous material for transportation or the person 
responsible for packing the materials into a cargo transport unit who 
does have knowledge of the chemical properties of such non-hazardous 
materials may identify a relevant segregation group and apply the 
segregation requirements for that segregation group.
    69. In Sec.  176.84, in the table of provisions in paragraph (b), 
Stowage provisions 19, 48, and 50 are deleted and Stowage provisions 25 
and 128 are revised and, in paragraph (c)(2), stowage provisions 7E, 8E 
and 20E are deleted, and Stowage provision 26E is revised to read as

Subpart S--Testing of Flexible Bulk Containers

Sec.  178.1030  Purpose and scope.

    This subpart prescribes certain testing requirements for Flexible 
Bulk Containers identified in subpart R of this part.

Sec.  178.1035  General requirements.

    (a) General. The test procedures prescribed in this subpart are 
intended to ensure that Flexible Bulk Containers containing hazardous 
materials can withstand normal conditions of transportation. These test 
procedures are considered minimum requirements. Each packaging must be 
manufactured and assembled so as to be capable of successfully passing 
the prescribed tests and to conform to the requirements of Sec.  173.24 
of this subchapter while in transportation.
    (b) Responsibility. The Flexible Bulk Container manufacturer is 
responsible for ensuring each Flexible Bulk Container is capable of 
passing the prescribed tests. To the extent a Flexible Bulk Container's 
assembly function, including final closure, is performed by the person 
who offers a hazardous material for transportation, that person is 
responsible for performing the function in accordance with Sec. Sec.  
173.22 and 178.2 of this subchapter.
    (c) Definitions. For the purpose of this subpart:
    (1) Flexible Bulk Container design type refers to a Flexible Bulk 
Container that does not differ in structural design, size, material of 
construction and packing.
    (2) Design qualification testing is the performance of the drop, 
topple, righting, tear, stacking, and top-lift tests prescribed in this 
subpart, for each different Flexible Bulk Container design type, at the 
start of production of that packaging.
    (3) Periodic design requalification test is the performance of the 
applicable tests specified in paragraph (c)(2) of this section on a 
Flexible Bulk Container design type, to requalify the design for 
continued production at the frequency specified in paragraph (e) of 
this section.
    (4) Production inspection is the inspection that must initially be 
conducted on each newly manufactured Flexible Bulk Container.
    (5) Different Flexible Bulk Container design type is one that 
differs from a previously qualified Flexible Bulk Container design type 
in structural design, size, material of construction, wall thickness, 
or manner of construction, but does not include:
    (i) A packaging that differs in surface treatment;
    (ii) A packaging that differs only in its lesser external 
dimensions (i.e., height, width, length) provided materials of 
construction and material thickness or fabric weight remain the same;
    (d) Design qualification testing. The packaging manufacturer must 
achieve successful test results for the design qualification testing at 
the start of production of each new or different Flexible Bulk 
Container design type. Application of the certification mark by the 
manufacturer constitutes certification that the Flexible Bulk Container 
design type passed the prescribed tests in this subpart.
    (e) Periodic design requalification testing. (1) Periodic design 
requalification must be conducted on each qualified Flexible Bulk 
Container design type if the manufacturer is to maintain authorization 
for continued production. The Flexible Bulk Container manufacturer must 
achieve successful test results for the periodic design requalification 
at sufficient frequency to ensure each packaging produced by the 
manufacturer is capable of passing the design qualification tests. 
Design requalification tests must be conducted at least once every 24 
months.
    (2) Changes in the frequency of design requalification testing 
specified in paragraph (e)(1) of this section are authorized if 
approved by the Associate Administrator.
    (f) Test samples. The manufacturer must conduct the design 
qualification and periodic tests prescribed in this subpart using 
random samples of packagings, in the numbers specified in the 
appropriate test section.
    (g) Proof of compliance. In addition to the periodic design 
requalification testing intervals specified in paragraph (e) of this 
section, the Associate Administrator, or a designated representative, 
may at any time require demonstration of compliance by a manufacturer, 
through testing in accordance with this subpart, to ensure packagings 
meet the requirements of this subpart. As required by the Associate 
Administrator, or a designated representative, the manufacturer must 
either:
    (1) Conduct performance tests or have tests conducted by an 
independent testing facility, in accordance with this subpart; or
    (2) Make a sample Flexible Bulk Container available to the 
Associate Administrator, or a designated representative, for testing in 
accordance with this subpart.
    (h) Record retention. Following each design qualification test and 
each periodic retest on a Flexible Bulk Container, a test report must 
be prepared. The test report must be maintained at each location where 
the Flexible Bulk Container is manufactured and each location where the 
design qualification tests are conducted, for as long as the Flexible 
Bulk Container is produced and for at least two years thereafter, and 
at each location where the periodic retests are conducted until such 
tests are successfully performed again and a new test report produced. 
In addition, a copy of the test report must be maintained by a person 
certifying compliance with this part. The test report must be made 
available to a user of a Flexible Bulk Container or a

[[Page 49275]]

representative of the Department upon request. The test report, at a 
minimum, must contain the following information:
    (1) Name and address of test facility;
    (2) Name and address of applicant (where appropriate);
    (3) A unique test report identification;
    (4) Date of the test report;
    (5) Manufacturer of the packaging;
    (6) Description of the flexible bulk container design type (e.g., 
dimensions materials, closures, thickness, etc.), including methods of 
manufacture (e.g., blow molding) and which may include drawing(s) and/
or photograph(s);
    (7) Maximum capacity;
    (8) Characteristics of test contents (e.g., particle size for 
solids);
    (9) Mathematical calculations performed to conduct and document 
testing (e.g., drop height, test capacity, outage requirements, etc.);
    (10) Test descriptions and results; and
    (11) Signature with the name and title of signatory.

Sec.  178.1040  Preparation of Flexible Bulk Containers for testing.

    (a) Except as otherwise provided in this subchapter, each Flexible 
Bulk Container must be closed in preparation for testing and tests must 
be carried out in the same manner as if prepared for transportation. 
All closures must be installed using proper techniques and torques.
    (b) If the material to be transported is replaced for test purposes 
by a non-hazardous material, the physical properties (grain, size, 
viscosity) of the replacement material used that might influence the 
results of the required tests must correspond as closely as possible to 
those of the hazardous material to be transported. It is permissible to 
use additives, such as bags of lead shot, to achieve the requisite 
total package mass, so long as they do not affect the test results.

Sec.  178.1045  Drop test.

    (a) General. The drop test must be conducted for the qualification 
of all Flexible Bulk Container design types and performed periodically 
as specified in Sec.  178.1035(e) of this subpart.
    (b) Special preparation for the drop test. Flexible Bulk Containers 
must be filled to their maximum permissible gross mass.
    (c) Test method. (1) A sample of all Flexible Bulk Container design 
types must be dropped onto a rigid, non-resilient, smooth, flat and 
horizontal surface. This test surface must be large enough to be 
immovable during testing and sufficiently large enough to ensure that 
the test Flexible Bulk Container falls entirely upon the surface. The 
test surface must be kept free from local defects capable of 
influencing the test results.
    (2) Following the drop, the Flexible Bulk Container must be 
restored to the upright position for observation.
    (d) Drop height. (1) For all Flexible Bulk Containers, drop heights 
are specified as follows: Packing group III: 0.8 m (2.6 feet)
    (2) Drop tests are to be performed with the solid to be transported 
or with a non-hazardous material having essentially the same physical 
characteristics.
    (e) Criteria for passing the test. For all Flexible Bulk Container 
design types there may be no loss of the filling substance. However a 
slight discharge (e.g., from closures or stitch holes) upon impact is 
not considered a failure of the Flexible Bulk Container provided that 
no further leakage occurs after the container has been restored to the 
upright position.

Sec.  178.1050  Top lift test.

    (a) General. The top lift test must be conducted for the 
qualification of all of Flexible Bulk Container design types to be 
lifted from the top.
    (b) Special preparation for the top lift test. Flexible Bulk 
Container design types must be filled to six times the maximum 
permissible gross mass, the load being evenly distributed.
    (c) Test method. (1) A Flexible Bulk Container must be lifted in 
the manner for which it is designed until clear of the floor and 
maintained in that position for a period of five minutes.
    (2) If not tested as indicated in paragraph (c)(1) of this section, 
a Flexible Bulk Container design type must be tested as follows:
    (i) Fill the Flexible Bulk Container to 95% full with a material 
representative of the product to be shipped.
    (ii) Suspend the Flexible Bulk Container by its lifting devices.
    (iii) Apply a constant downward force through a specially designed 
platen. The platen will be a minimum of 60 percent and a maximum of 80 
percent of the cross sectional surface area of the Flexible Bulk 
Container.
    (iv) The combination of the mass of the filled Flexible Bulk 
Container and the force applied through the platen must be a minimum of 
six times the maximum net mass of the Flexible Bulk Container. The test 
must be conducted for a period of five minutes.
    (v) Other equally effective methods of top lift testing and 
preparation may be used with approval of the Associate Administrator.
    (d) Criterion for passing the test. For all Flexible Bulk Container 
design types designed to be lifted from the top, there may be no damage 
to the Flexible Bulk Container or its lifting devices that renders the 
Flexible Bulk Container unsafe for transport, and no loss of contents.

Sec.  178.1055  Stacking test.

    (a) General. The stacking test must be conducted for the 
qualification of all Flexible Bulk Containers design types.
    (b) Special preparation for the stacking test. All Flexible Bulk 
Containers design types must be loaded to their maximum permissible 
gross mass.
    (c) Test method. (1) All Flexible Bulk Containers must be placed on 
their base on level, hard ground and subjected to a uniformly 
distributed superimposed test load that is four times the design type 
maximum gross weight for a period of at least twenty-four hours.
    (2) For all Flexible Bulk Containers, the load must be applied by 
one of the following methods:
    (i) Four Flexible Bulk Containers of the same type loaded to their 
maximum permissible gross mass and stacked on the test Flexible Bulk 
Container;
    (ii) The calculated superimposed test load weight loaded on either 
a flat plate or a reproduction of the base of the Flexible Bulk 
Container, which is stacked on the test Flexible Bulk Container.
    (d) Criterion for passing the test. There may be no deterioration 
that renders the Flexible Bulk Container unsafe for transportation and 
no loss of contents during the test or after removal of the test load.

Sec.  178.1060  Topple test.

    (a) General. The topple test must be conducted for the 
qualification of all Flexible Bulk Containers design types.
    (b) Special preparation for the topple test. Flexible Bulk 
Container design types must be filled to their maximum permissible 
gross mass, the load being evenly distributed.
    (c) Test method. Samples of all Flexible Bulk Container design 
types must be toppled onto any part of its top by lifting the side 
furthest from the drop edge upon a rigid, non-resilient, smooth, flat 
and horizontal surface. This test surface must be large enough to be 
immovable during testing and sufficiently large enough to ensure that 
the test Flexible Bulk Container falls entirely upon the surface. The 
test surface must be kept free from local defects capable of 
influencing the test results.
    (d) Topple height. (1) For all Flexible Bulk Containers, topple 
heights are specified as follows: Packing group III: 0.8 m (2.6 feet)

[[Page 49276]]

    (e) Criterion for passing the test. For all Flexible Bulk Container 
design types there may be no loss of the filling substance. However a 
slight discharge (e.g., from closures or stitch holes) upon impact 
shall not be considered to be a failure of the Flexible Bulk Container.

Sec.  178.1065  Righting test.

    (a) General. The righting test must be conducted for the 
qualification of all Flexible Bulk Containers design types designed to 
be lifted from the top or side.
    (b) Special preparation for the righting test. Flexible Bulk 
Container design types must be filled to not less than 95% of their 
capacity and to their maximum permissible gross mass, the load being 
evenly distributed.
    (c) Test method. A sample Flexible Bulk Container design type must 
be tested; the Flexible Bulk Container should start lying on its side 
and then must be lifted at a speed of at least 0.1m/s (0.328 ft/s) to 
an upright position clear of the floor, by no more than half of the 
lifting devices.
    (d) Criterion for passing the test. For all Flexible Bulk Container 
design types there shall be no damage that renders the Flexible Bulk 
Container unsafe for transport or handling.

Sec.  178.1070  Tear test.

    (a) General. The tear test must be conducted for the qualification 
of all of Flexible Bulk Containers design types.
    (b) Special preparation for the tear test. Flexible Bulk Container 
design types must be filled its maximum permissible gross mass, the 
load being evenly distributed.
    (c) Test method. (1) A Flexible Bulk Container design type must be 
placed on the ground and a 300 mm (11.9 in) cut shall be made. This 300 
mm (11.9 in) cut must:
    (i) Completely penetrate all layers of the Flexible Bulk Container 
on a wall with a wide face.
    (ii) Be made at a 45[deg] angle to the principal axis of the 
Flexible Bulk Container, halfway between the bottom surface and the top 
level of the contents.
    (2) The Flexible Bulk Container after being cut according to the 
provisions of Sec.  178.1070(c)(1), must be subjected to a uniformly 
distributed superimposed load equivalent to twice the maximum gross 
mass of the package. This load must be applied for at least fifteen 
minutes. Flexible Bulk Containers that are designed to be lifted from 
the top or the side must, after removal of the superimposed load, be 
lifted clear of the floor and maintained in that position for a period 
of fifteen minutes
    (d) Criterion for passing the test. For all Flexible Bulk Container 
design types, the cut must not spread more than an additional 25% of 
its original length.
