I. Executive Summary

    PHMSA proposes to amend the HMR 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 
provide an appropriate level of safety. 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 2015-2016 International 
Civil Aviation Organization Technical Instructions for the Safe 
Transport of Dangerous Goods by Air (ICAO TI), Amendment 37-14 to the 
International Maritime Dangerous Goods Code (IMDG Code), the

[[Page 50743]]

International Atomic Energy Agency (IAEA) Safety Standards for 
Protecting People and the Environment; Regulations for the Safe 
Transport of Radioactive Material, No. SSR-6, (IAEA Regulations), 2012 
Edition, and the 18th Revised Edition of 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) published 
November 9, 2011; Amendment 9 (SOR/2011-60) published March 16, 2011; 
Amendment 10 (SOR/2011-210) published October 12, 2011; and Amendment 
11 (SOR/2012-245) published November 9, 2012. Finally, in this NPRM, 
PHMSA is proposing the adoption of updated International Standards 
Organization (ISO) standards.
     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 18th Revised Edition of the UN Model 
Regulations, the IMDG Code, and the ICAO TI.
     Provide Exceptions for Marine Pollutants: PHMSA is 
proposing an exception from the HMR for marine pollutants up to 5 l 
(1.3 gal) for liquids or 5 kg (11 lbs.) for solids when these materials 
are packaged in accordance with the general packaging requirements of 
Sec. Sec.  173.24 and 173.24a. The proposed amendment would exempt 
small packages of hazardous material from the HMR that are regulated 
only because of the presence of one or more marine pollutants. 
Materials in these quantities pose a low risk in transport and this 
proposal simplifies the current exceptions for marine pollutants and 
reduces impediments to multi-modal transport of these goods. The 
proposed changes to the HMT mirror recent changes in the Dangerous 
Goods list of the 18th Revised Edition of the UN Model Regulations, the 
IMDG Code, and the ICAO TI.
     Modification of the Marine Pollutant List: PHMSA is 
proposing to modify the list of marine pollutants in Appendix B to 
172.101. The HMR maintain a list as the basis for regulating substances 
toxic to the aquatic environment and allow use of the criteria in the 
IMDG Code if a listed material does not meet the criteria for a marine 
pollutant. PHMSA periodically updates its list based on changes to the 
IMDG Code and evaluation of listed materials.
     Clarify Hazard Communication Size Requirements: PHMSA is 
proposing to add minimum sizes for the OVERPACK and SALVAGE markings. 
These markings would be characters at least 12 mm (.47 inches) high. 
There is no minimum size for these marks currently in the HMR, and the 
information is not always readily visible. Further, the HMR already 
prescribe specific size requirements for the ``UN'' or ``NA'' markings 
and package specification markings. This proposal is a logical 
extension of existing requirements. To offset any increased cost 
associated with the proposed size requirements, PHMSA will propose to 
permit a permanently marked salvage package or overpack to remain in 
service with its existing marks regardless of whether the 
identification number markings meet the minimum size requirements.
     Revise Vessel Stowage Requirements: PHMSA is proposing to 
revise and add vessel stowage codes listed in column 10B of the HMT and 
segregation requirements in Sec.  176.83 consistent with the IMDG Code. 
These changes would harmonize the HMR with the IMDG Code and would 
provide additional guidance on the loading and stowage of various 
materials. Additionally, we propose to increase the required 
segregation distances between Division 4.3 dangerous when wet material 
(i.e. materials liable to give off a flammable or toxic gas in contact 
with water) and Class 3 flammable liquids and Division 2.1 flammable 
gases.
     Addition of Entries for Adsorbed Gases in the Hazardous 
Materials Table: Consistent with amendments adopted into the UN Model 
Regulations, PHMSA is proposing to revise the Hazardous Materials Table 
(HMT) in Sec.  172.101 to include seventeen new entries for adsorbed 
gases. Additionally we propose to add into the HMR a definition for 
adsorbed gas, authorized packagings, and safety requirements including 
but not limited to quantity limitations and filling limits.
     Harmonized Requirements for Lithium Batteries: PHMSA 
proposes harmonization with the latest version of the ICAO Technical 
Instructions to ensure that the information currently authorized by the 
HMR to be provided by means of an alternative document be included on a 
shipping paper for batteries transported under the provisions of 49 CFR 
173.185(c)(4)(v)--equivalent to Section IB of ICAO Packing Instructions 
965 and 968. PHMSA also proposes to harmonize with the latest version 
of the ICAO Technical Instructions by requiring a ``CARGO AIRCRAFT 
ONLY'' label on packages containing small lithium metal batteries not 
packed in or with equipment.
     Definition of Non-Bulk Packaging: PHMSA proposes to revise 
the HMR definition of non-bulk packaging by adding a new paragraph (4) 
to include bags and boxes conforming to the applicable requirements for 
specification packagings in subpart L of part 178 of this subchapter, 
if they have a maximum net mass of 400 kg (882 pounds) or less. The UN 
Model regulations were revised to remove the volumetric limit for 
certain packaging types considered in Part 6 of the UN Model 
Regulations that would be considered non-bulk packagings under the HMR. 
This change was based on recognition by the UN Transport of Dangerous 
Goods Sub-Committee that there are packagings suitable for the 
transportation of high volume, low mass materials (e.g., airbags).
    If the amendments in this proposed rule are not adopted in the HMR 
by January 1, 2015, the date most of the international standards above 
take effect, U.S. companies, including numerous small entities 
competing in foreign markets, will be at an economic disadvantage. 
These companies will be forced to comply with a dual system of 
regulations. The amendments proposed in this rulemaking are intended to 
avoid this result.
    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 regarding approaches to reducing the

[[Page 50744]]

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 United Nations Subcommittee of Experts 
(UNSCOE) on the Transport of Dangerous Goods 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 TI.
    Since publication of the 1990 rule, PHMSA has issued ten 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]; HM-215K [76 FR 3308]; and HM-215L [78 FR 
987]. These rulemakings were based on biennial updates of the UN Model 
Regulations, the IMDG Code, and the ICAO TI.
    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 ensure 
safety or 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 18th 
Revised Edition of the UN Model Regulations, Amendment 37-14 to the 
IMDG Code, and the 2015-2016 Edition of the ICAO Technical 
Instructions, which become effective January 1, 2015 (The IMDG Code is 
effective January 1, 2015; however, the previous amendment may continue 
to be used until January 1, 2016).
    In addition, PHMSA proposes to incorporate by reference 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, 2015.

Possible Interim Final Rule

    If the changes in this proposed rule are not adopted by January 1, 
2015, 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, 2015. Therefore, it is 
essential that a final rule incorporating these standards by reference 
be published no later than December 31, 2014 with an effective date of 
January 1, 2015. To this end, if it appears a final rule under this 
docket will not be published prior to January 1, 2015, PHMSA will 
publish a bridging document in the form of an interim final rule to 
amend the HMR by incorporating the 18th Revised Edition of the UN 
Recommendations and the 2015-2016 Edition of the ICAO Technical 
Instructions.
    With regard to Amendment 37-14 of the IMDG Code, the International 
Maritime Organization approved an implementation date of January 1, 
2016. The current edition of the IMDG Code (Amendment 36-12) remains in 
effect through 2015 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-2013-0260 (HM-
215M). Accordingly, any interim final rule will only incorporate by 
reference editions of the international standards that become effective 
on January 1, 2015.

III. Harmonization Proposals in This NPRM

    In addition to various other revisions to the HMR, in this NPRM, 
PHMSA is proposing the following amendments to harmonize the HMR with 
the most recent revisions to the UN Model Regulations, ICAO TI, and the 
IMDG Code:

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, vessel stowage and segregation requirements, and 
passenger and cargo aircraft maximum quantity limits.

Incorporation by Reference

    In this NPRM, PHMSA proposes to incorporate by reference the latest 
editions of various international transport standards including the 
2015-2016 Edition of the ICAO Technical Instructions, Amendment 37-14 
of the IMDG Code, and the 18th 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) published November 9, 
2011; Amendment 9 (SOR/2011-60) published March 16, 2011; Amendment 10 
(SOR/2011-210) published October 12, 2011; and Amendment 11 (SOR/2012-
245) published November 9, 2012.

[[Page 50745]]

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.
    Petitions for Rulemaking: In this NPRM, PHMSA is addressing three 
petitions for rulemaking:

Alignment of the HMR With the ICAO TI To Remove the Segregation 
Requirements in Sec.  175.630 (P-1631)

    In a petition for rulemaking (P-1631), UPS, Inc. requests that 
PHMSA align with the ICAO TI by removing the Sec.  175.630 provisions 
requiring Division 6.1 and 6.2 packages to be segregated from materials 
marked as or known to be a foodstuff, feed, or any other edible 
material intended for consumption by humans or animals.
    Section 175.630 imposes special segregation requirements for 
Division 6.1 (toxic) material and Division 6.2 (infectious substance) 
materials when transported by aircraft. Paragraph (a) requires that a 
package required to bear a POISON, POISON INHALATION HAZARD, or 
INFECTIOUS SUBSTANCE label may not be carried in the same compartment 
of an aircraft with material which is marked as or known to be a 
foodstuff, feed, or any other edible material intended for consumption 
by humans or animals unless:
    (1) The Division 6.1 or Division 6.2 material and the foodstuff, 
feed, or other edible material are loaded in separate unit load devices 
which, when stowed on the aircraft, are not adjacent to each other; or
    (2) The Division 6.1 or Division 6.2 material are loaded in one 
closed unit load device and the foodstuff, feed or other material is 
loaded in another closed unit load device.
    The petitioner notes that during 2012-2013 biennium, the ICAO 
Dangerous Goods Panel (DGP) determined that the high quality of 
packaging for Division 6.1 and 6.2 material required by the ICAO TI 
justified removal of the segregation requirements applied to Division 
6.1 or Division 6.2 material and foodstuffs. The petitioner states that 
the alignment of the HMR with the ICAO TI on the matter of operator 
requirements is of great value for aircraft operators. In addition, the 
petitioner states that this amendment has the potential to introduce 
efficiencies for air carriers, including UPS. In this context, with the 
deletion of ICAO TI Part 7, Section 2.9, the petitioner recommends and 
requests that PHMSA remove the corresponding requirements of Sec.  
175.630.
    PHMSA is in agreement with the petitioner and in this NPRM, is 
proposing to delete the special segregation requirements for Division 
6.1 and Division 6.2 material. This action would harmonize the HMR with 
recent amendments that will appear in the 2015-2016 Edition of the ICAO 
TI. These segregation requirements are no longer necessary, and we 
propose to harmonize with ICAO because of: (1) The relative rarity of 
releases of toxic and infectious substances; (2) the small quantities 
released when a spill actually occurs; (3) the robust nature of 
combination packagings used for toxic and infectious substances; (4) 
the acceptance checks required by operators prior to loading hazardous 
materials aboard aircraft; (5) the lack of evidence of contamination of 
other packages by a release of toxic or infectious substances; and (6) 
the coverage by the hazard communication system already in place in the 
event of a release.

Passenger Notification Programs for Tickets Issued by Phone (P-1623)

    In a petition for rulemaking (P-1623), the Council on Safe 
Transportation of Hazardous Articles (COSTHA) requests that PHMSA 
remove the applicability of passenger notifications in Sec.  175.25(b) 
to telephone transactions.
    In a final rule published January 19, 2011 under Docket No. PHMSA-
2009-0126 (HM-215K); 76 FR 3308, PHMSA aligned with the ICAO TI by 
adding new requirements for certain information to be presented to 
passengers regarding what hazardous materials they may check-in or 
carry-on a flight. This information is to be provided at points of 
ticket sale and at automated or remote passenger check-in. On March 7, 
2013, PHMSA received a request for a letter of interpretation 
(Reference 13-00058) from COSTHA pointing out that the January 19, 2011 
final rule in Sec.  175.25 (b) includes the word ``phone'' which is not 
in Part 7; 5.1.1 of the ICAO TI, nor is it part of the current scope of 
passenger notification programs. COSTHA requested clarification as to 
whether or not PHMSA intended the Sec.  175.25(b) requirement to be 
applicable to passenger notification by telephone. In the July 11, 2013 
response, PHMSA stated that Sec.  175.25(b) explicitly references 
purchase by telephone as a means of purchasing a ticket remotely. 
Therefore, as written, the Sec.  175.25(b) passenger notification and 
acknowledgement requirements apply when purchasing a ticket by 
telephone and this is generally consistent with Part 7; 5.1.1 of the 
ICAO TI. This petition was submitted in response to the letter of 
interpretation issued by PHMSA on July 11, 2013 (Reference 13-0058).
    In its petition, COSTHA states that they strongly disagree with 
PHMSA's position that inclusion of the term ``phone'' in Sec.  
175.25(b) is ``generally consistent'' with the language adopted in Part 
7; 5.1.1 of the ICAO TI, and that PHMSA has not fully recognized or 
accounted for the significant costs such an interpretation would impose 
on industry and the competitive disadvantage that would result for U.S. 
passenger air carriers. The petitioner notes that the issue of ticket 
purchase and check-in on line was discussed within a working group of 
the ICAO DGP (May 2009) and that the discussion only pertained to 
electronic transactions, not telephone transactions. The report from 
the meeting specifically states ``when purchasing tickets or checking 
in electronically.'' The report includes comments from DGP members 
questioning who would enforce the requirement against internet-based 
travel agencies. There is no reference to ticket purchases made via 
telephone. At the 22nd meeting of the ICAO DGP (October 2009), ICAO 
adopted modifications to Part 7; 5.1 to bolster communication to 
passengers who purchase tickets or check-in electronically. Paragraph 
2.8.2.1 from the DGP 22 report states:

    A proposal to strengthen the requirements for the provision of 
information to passengers in respect of dangerous goods in baggage 
was discussed. It was suggested the use of the Internet to purchase 
tickets, to check in, and the use of automated check-in machines at 
the airport or by telephone made traditional methods of providing 
information to passengers obsolete. New text in Part 7;5.1 was 
developed to address this.

    The petitioner notes that DGP 23 report contains the first 
reference to the use of telephones, and in this case it is in reference 
to passenger check-ins, not ticket purchase. Further revisions to the 
ICAO TI text resulted in mandatory requirements. However, the context 
of these discussions was again regarding electronic transactions, not 
via the telephone. The petitioner states based on the information 
contained in the ICAO reports that it was not the intention of ICAO to 
require extensive hazard communication during telephonic ticket 
purchases.
    The petitioner states that by extending the application of 
notification to passengers to telephonic ticket purchases, PHMSA is 
imposing

[[Page 50746]]

significant training and implementation costs on industry and that 
these costs may not have been fully considered. In the petition, COSTHA 
includes estimated costs from three member air carriers for providing 
passenger notification via telephonic communication. One carrier 
estimated an annual cost increase of $17 million, another $750,000, and 
the third $450,000 a year for every second added to talk time. These 
figures do not include employee training costs. In addition, these 
three airlines provided data that between 3% and 5.1% of tickets are 
purchased over the phone. The petitioner points out that the vast 
majority of tickets are purchased on-line, and when purchased in this 
manner, passengers are notified about hazardous materials at the time 
of purchase, during check-in, and again via an announcement at the 
gate. The petitioner states that extending these requirements to 
telephone transactions will significantly increase costs to industry 
while reaching only 5% of passengers purchasing tickets.
    In this NPRM, PHMSA is proposing to grant this petition by adopting 
into the HMR the revisions made to the passenger notification 
provisions of Part 7;5.1 of the ICAO TI adopted at the 24th meeting of 
ICAO DGP (October 2013). Paragraph 2.7.3.1 from the DGP 24 report 
states:

    It was suggested that text which had existed in Part 7;5.1 prior 
to the 2011-2012 Edition of the Technical Instructions had been 
inadvertently removed and should be reinstated. Part 7;5.1 was 
amended in the 2011-2012 Edition to address the increasing use of 
the internet for flight bookings and check-in, the use of telephones 
and kiosks at airports for check-in. It was suggested, however, that 
the new text did not address cases when a passenger might make a 
booking over the telephone with the operator providing the dangerous 
goods information with a booking confirmation by post or email.

    Specifically, PHMSA is proposing to revise Sec.  175.25(b) for 
consistency with the ICAO TI to clarify that for ticket purchases the 
hazardous materials notification must be presented at the point of 
ticket purchase or, if this not practical, made available in another 
manner to passengers prior to the check-in process. This will allow an 
operator to provide the hazardous materials notification verbally, with 
the ticket or ticket receipt, or using another equally suitable method. 
In addition, PHMSA is proposing to remove the words ``regardless if the 
process is completed remotely (e.g., via the Internet and Phone) or 
when completed at the airport, with or without assistance from another 
person (e.g., automated check in facility)'' as examples of ticket 
purchases to fully harmonize Sec.  175.25(b) with the ICAO TI, and to 
clarify that the hazardous materials notification must be given with 
every ticket purchase. Finally, it is proposed to insert the words 
``provided via the internet'' into the second sentence of Sec.  
175.25(b) to clarify that passenger acknowledgement is only required 
when the ticket is purchased through the internet without assistance 
from another person. All of these proposed changes taken together will 
address the COSTHA petition and bring the HMR into full alignment with 
the ICAO TI.

Compliance Date Extension for Passenger Notification Programs (P-1633)

    In a petition for rulemaking (P-1633), COSTHA requests that PHMSA 
extend the transitional compliance date for ``hazardous materials 
notifications to passengers at time of ticket purchase,'' which was 
adopted in a January 19, 2011 final rule (Docket No. PHMSA-2009-0126 
(HM-215K); 76 FR 3308) and extended to January 1, 2015 in a final rule 
published January 7, 2013 (Docket No. PHMSA-2009-0126 (HM-215K); 78 FR 
1108). Specifically, COSTHA requests the current compliance date for 
passenger notifications requirements in Sec.  175.25 be extended from 
January 1, 2015 until 12 months from the effective date of the HM-215M 
final rule publication, or January 1, 2016, whichever is later.
    The petitioner states on April 30, 2013, the Federal Aviation 
Administration (FAA) chartered an Aviation Rulemaking Committee (ARC) 
on Passenger Notification of Hazardous Materials Regulations with a 
mission to develop consistent and effective messages for disseminating 
hazardous materials information to passengers and provide air carriers 
additional clarity to ensure regulatory compliance. The FAA timeline 
for the ARC and publication of the draft advisory circular was 
developed to provide air carriers eight months to implement the 
recommendations, employee training, program changes and to make 
necessary technology updates. Due to additional amendments to the 
passenger notification requirements of the ICAO TI the implementation 
and subsequent consideration for harmonization under this proposed rule 
the timeline established by the FAA was delayed. Given this delay, air 
carriers will not be provided sufficient time to implement changes 
necessary to comply with the modified Sec.  175.25.
    In this NPRM, PHMSA is proposing to revise Sec.  175.25(b) for 
consistency with recent amendments to the ICAO TI to clarify that for 
ticket purchases made via the telephone, the hazardous materials 
notification must be provided to the passenger but can be done so using 
any suitable method prior to the check-in. Due to this revision, the 
extension requested in this petition is unnecessary. The requirement 
for air carrier reservation agents to verbally provide passenger 
notification at the time of purchase by telephone was the basis for the 
effective date extension granted in the January 7, 2013 final rule (HM-
215K). By removing the telephonic acknowledgement requirement, the 
previous effective date of January 1, 2015 will be waived as of 
publication. Other than the telephonic acknowledgement requirement, 
PHMSA is unaware of any additional new requirement imposed under HM-
215K that has posed difficulty in implementation that would merit 
providing additional compliance date relief. Further, proposed 
amendments to Sec.  175.25 in this rulemaking are eligible for the one 
year delayed compliance.

IV. Amendments Not Being Considered for Adoption in this NPRM

    This NPRM proposes changes to the HMR based on amendments adopted 
in the 18th Revised Edition of the UN Model Regulations, the 2015-2016 
Edition of the ICAO Technical Instructions, and Amendment 37-14 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

[[Page 50747]]

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:

Damaged, Defective, and Waste Lithium Batteries

    The 18th Revised Edition of the UN Model Regulations adopted 
transportation provisions for damaged, defective, and waste lithium 
batteries. In this NPRM, PHMSA is not proposing to adopt changes to the 
domestic requirements for the treatment of these lithium batteries, as 
we believe existing HMR requirements sufficiently address shipments of 
this nature.

Dimensions on Hazard Communication Examples

    The 18th Revised Edition of the UN Model Regulations adopted 
modifications to example figures of markings, labels, and placards to 
note minimum dimensions for the appropriate hazard communication 
example pictograms. In this NPRM, PHMSA is not proposing to adopt the 
changes to example markings, labels, and placards found in the HMR. We 
believe the addition of dimensions to the example pictograms does not 
add significant value because these dimensions are described in the 
text of the HMR. These amendments to the international recommendations 
and regulations are not being adopted because the regulatory text 
associated with the various figures in the HMR depicting package 
markings, labels and placards adequately describes the item without 
adding minimum dimensions to the example figures.

Flash Composition

    The 18th Revised Edition of the UN Model Regulations amended a note 
before the default fireworks classification table in 2.1.3.5.5. This 
amendment changed the criteria used in the meaning of ``flash 
composition'' from 8 ms for .5 g of pyrotechnic substance in the HSL 
Flash Composition Test in Appendix 7 of the Manual of Tests and 
Criteria, to 6 ms for .5 g of pyrotechnic substance. In this NPRM, 
PHMSA is not adopting this change as work on this test is ongoing.

Radioactive Materials Transportation Requirements

    The 18th Revised Edition of the UN Model Regulations, the 2015-2016 
Edition of the ICAO Technical Instructions, and Amendment 37-14 to the 
IMDG Code amended various radioactive transportation requirements to 
harmonize their regulations with the International Atomic Energy Agency 
(IAEA) Safety Standards for Protecting People and the Environment; 
Regulations for the Safe Transport of Radioactive Material, No. SSR-6. 
While PHMSA is proposing to incorporate by reference this document (see 
Sec.  171.7) and adopt the new proper shipping name and associated 
shipping requirements for UN 3507, Uranium hexafluoride, radioactive 
material, excepted package, we are not proposing to harmonize the HMR 
with the remainder of the changes made by the various international 
regulations in this NPRM. Any further domestic radioactive 
harmonization issues will be addressed in a future rulemaking in 
conjunction with the Nuclear Regulatory Commission.

Discarded Packages

    The 18th Revised Edition of the UN Model Regulations adopted a new 
proper shipping name and UN number for Packaging discarded, empty, 
uncleaned, UN 3509. This new proper shipping name was brought in to 
allow, with competent authority approval, packagings, large packagings 
or intermediate bulk containers, or parts thereof, which have contained 
hazardous materials, other than radioactive material to be transported 
for disposal, recycling or recovery of their material, other than 
reconditioning, repair, routine maintenance, remanufacturing or reuse, 
and which have been emptied to the extent that only residues of 
dangerous goods adhering to the packaging parts are present when they 
are presented for transport. This change was made primarily to address 
European land transport of packages that are no longer within 
appropriate package specifications. The ICAO DGP did not incorporate 
this entry into the ICAO TI dangerous goods list, and the IMDG Code has 
adopted very limited allowance for the use of this entry on short sea 
voyages.
    PHMSA is not proposing to include a hazardous materials table entry 
for UN 3509 Packaging discarded, empty, uncleaned. We believe that the 
shipment of empty uncleaned packaging is adequately addressed by HMR 
under existing empty packaging provisions in Sec.  173.29 and 
additional sections. Use of this description in the UN Model 
Regulations requires authorization by the competent authority, which 
can still be obtained from PHMSA via a special permit.

Used Medical Devices

    In the 2015-2016 Edition of the ICAO TI a note was added to an 
exception for used medical devices which excepts medical devices or 
equipment that have been drained of free liquid to the extent 
practicable; and clarifying that any capability requirement in the ICAO 
TI can be determined through testing a sample package as prepared for 
transport, or through alternative means such as non-destructive 
testing, engineering analysis, testing with an article of similar mass 
and size, or other equivalent means. PHMSA is not making any 
corresponding amendments to Sec.  173.134, as we believe the existing 
HMR satisfactorily addresses the hazards presented by used medical 
devices in transportation.

Coolants, Conditioners, and Asphyxiates

    The 18th Revised Edition of the UN Model Regulations contains 
various editorial amendments applicable to packages and cargo transport 
units containing substances presenting a risk of asphyxiation when used 
for cooling or conditioning purposes. PHMSA did not adopt requirements 
for these shipments instituted in the 17th Revised Edition of the UN 
Model Regulations, and will not be adopting any of the editorial 
amendments incorporated into the 18th UN Model Regulations either. 
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.

Gas Cartridge and Fuel Cell Testing

    The 18th Revised Edition of the UN Model Regulations was amended to 
authorize alternatives to the water bath test for gas cartridges and 
fuel cells. PHMSA believes that the current requirements provided by 
the HMR for testing these items adequately address the hazards 
associated with their use.

V. Section-by-Section Review

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

Part 171

    Section 171.4 prohibits the transportation of materials meeting the 
definition of a marine pollutant except in accordance with HMR 
requirements. Paragraph (c) provides that marine pollutants transported 
in non-bulk packagings are excepted from the HMR unless the 
transportation is by vessel. In this NPRM, PHMSA proposes a new 
exception from the HMR for marine

[[Page 50748]]

pollutants up to 5 l (1.3 gallons) for liquids or 5 kg (11 lbs) for 
solids when these materials are packaged in accordance with the general 
packaging requirements of Sec. Sec.  173.24 and 173.24a. This proposed 
amendment, applicable to all modes, would exempt small packages of 
hazardous material from the HMR that are regulated only because of the 
presence of one or more marine pollutants. Materials in these 
quantities pose a low risk in transport and this proposal simplifies 
the current exceptions for marine pollutants and reduces impediments to 
multi-modal transport of these goods.
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 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 and 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 for the 
following organizations:
    Paragraph (s)(1) which incorporates the International Atomic Energy 
Agency (IAEA) Regulations for the Safe Transport of Radioactive 
Material 1996 edition would be revised to incorporate the SSR-6 2012 
Edition. To address concerns over domestic and international 
differences in the transport conditions applicable to shipments of 
excepted fissile materials, PHMSA is proposing to add additional 
requirements to Sec.  171.23 to ensure domestic concerns are addressed. 
Please see the discussion in the Section-by-Section Review under Sec.  
171.23 for a summary of proposed changes.
    Paragraph (t)(1) which incorporates the International Civil 
Aviation Organization Technical Instructions for the Safe Transport of 
Dangerous Goods by Air, 2013-2014 Edition would be revised to 
incorporate the 2014-2015 Edition.
    Paragraph (v)(2), which incorporates the International Maritime 
Organization International Maritime Dangerous Goods Code, 2012 Edition, 
Incorporating Amendment 36-12, English Edition, Volumes 1 and 2, would 
be revised to incorporate the 2014 Edition, Amendment 37-14.
    In paragraph (w) various International Organization for 
Standardization (ISO) entries which contain standards for the 
specifications, design, construction, testing and use of gas cylinders 
are proposed for incorporation by reference.
    In paragraph (bb)(1), the Transport Canada, Transportation of 
Dangerous Goods Regulations, including Clear Language Amendments 1 
through 7 sub-paragraphs (ix), (x), (xi), and (xii), would be added to 
include Amendment 8 (SOR/2011-239) which was published on November 9, 
2011; Amendment 9 (SOR/2011-60) published March 16, 2011; Amendment 10 
(SOR/2011-210) published October 12, 2011; and Amendment 11 (SOR/2012-
245) published November 9, 2012 respectively. In the preamble of our 
January 7, 2013 final rule (HM215-L [78 FR 987]) we indicated we were 
adopting Amendments 8, 9 and 10 of the Transportation of Dangerous 
Goods Regulations, however this adoption inadvertently did not appear 
in the published regulatory text. To correct this oversight, we are 
again proposing the adoption of Amendments 8, 9 and 10, along with the 
proposed adoption of the most recent, Amendment 11.
    Paragraph (dd)(1), the United Nations Recommendations on the 
Transport of Dangerous Goods--Model Regulations, 17th Revised Edition 
(2011), Volumes I and II, would be revised to incorporate the 18th 
Revised Edition (2013), Volumes I and II.
    Paragraph (dd)(2), the United Nations Recommendations on the 
Transport of Dangerous Goods--Manual of Tests and Criteria, Fifth 
Revised Edition (2009), including Amendment 1 (2011), would be revised 
to reference Sec.  171.24, and sub-paragraph (iii) would be added to 
incorporate Amendment 2 (2013).
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 terms:
    Adsorbed gas: The proposed adoption of this term directs the reader 
to Sec.  173.115 for the definition. See the Sec.  173.115 entry of the 
Section-by-Section Review for a complete discussion of the proposed 
adoption of the definition of adsorbed gas.
    Bundle of cylinders: Consistent with the ICAO TI, in this NPRM, 
PHMSA proposes to amend this definition to clarify that a ``bundle of 
cylinders'' is not permitted for air transport.
    Large salvage packaging: Consistent with the UN Model Regulations, 
in this NPRM, PHMSA proposes to define a large salvage packaging. A 
large salvage packaging is a special packaging into which damaged, 
defective or leaking hazardous materials packages, or hazardous 
materials that have spilled or leaked are placed for the purpose of 
transport for recovery or disposal. The general requirements for a 
large salvage packaging are consistent with the existing requirements 
for a ``large packaging.'' Large salvage packagings are not authorized 
for air transport.
    Neutron radiation detector: Consistent with the UN Model 
Regulations, in this NPRM, PHMSA proposes to define a neutron radiation 
detector. A neutron radiation detector is a device that detects neutron 
radiation. In such a device, a gas may be contained in a hermetically 
sealed electron tube transducer that converts neutron radiation into a 
measurable electric signal.
    Non-bulk packaging: The UN Model regulations were revised to remove 
the volumetric limit for certain packaging types considered in Part 6 
of the UN Model Regulations that would be considered non-bulk 
packagings under the HMR. This was based on recognition by the UN 
Transport of Dangerous Goods Sub-Committee that there are packagings 
suitable for the transportation of high volume, low mass materials 
(e.g., airbags) where the capacity of a box may exceed 450 liters (119 
gallons) while the net mass of the box is less than 400 kg (882 
pounds). Absent a corresponding amendment to the HMR, U.S. 
manufacturers and shippers would be placed at a

[[Page 50749]]

competitive disadvantage by not being authorized to use the same 
packaging configurations other than as authorized for use by Part 171 
Subpart C (use of international transport standards and regulations). 
Therefore, to maintain consistency with the UN Model Regulations, and 
to authorize the use of these packaging configurations for domestic 
transport, PHMSA proposes to revise the HMR definition of non-bulk 
packaging by adding a new paragraph (4) to include bags and boxes 
conforming to the applicable requirements for specification packagings 
in subpart L of part 178 of this subchapter, if they have a maximum net 
mass of 400 kg (882 pounds) or less. Based on our review of the UN 
Model Regulations, these are the only packagings affected by the UN 
amendment as only bags and boxes are authorized by specification to 
exceed 450 liters capacity.
    Radiation Detection System: Consistent with the UN Model 
Regulations, in this NPRM, PHMSA proposes to define a radiation 
detection system. A radiation detection system is an apparatus that 
contains radiation detectors as components.
Section 171.23
    Section 171.23 prescribes requirements for specific materials and 
packagings transported under various international standards. Section 
171.22(b)(2) requires shipments made in accordance with an authorized 
international standard or regulation to conform to all applicable 
requirements of Subpart C of Part 171.
    Paragraph (b)(2) of this section provides the requirement that the 
shipping paper description of items such as air bag inflators, air bag 
modules, and seat-belt pretensioners conform to the requirements in 
Sec.  173.166(c). Consistent with the UN Model Regulations, in this 
NPRM, PHMSA proposes to revise the proper shipping name of these items 
to read ``Safety device,'' with the addition of the term 
``pyromechanical device'' being included as a ``Safety device.'' 
Paragraph (b)(2) is being revised to reference the new proper shipping 
name, ``Safety device'' and the new term ``pyromechanical device.'' As 
a consequence of the addition of the proper shipping name ``Safety 
devices, pyrotechnic,'' and special provision 161 being removed, 
paragraph (b)(2)(ii) is removed and reserved.
    Paragraph (11) of this section prescribes additional requirements 
for shipments of radioactive materials made under authorized 
international standards or regulations. In this NPRM, PHMSA is 
proposing to incorporate by reference the 2012 IAEA SSR-6 regulations 
to allow shipments to be offered for transportation or transported 
under the most recent IAEA regulations. Several changes to the 
definition of excepted fissile materials and the requirements for its 
transport were adopted by the IAEA. Under their respective statutory 
authorities, DOT and the Nuclear Regulatory Commission (NRC) jointly 
regulate the transportation of radioactive materials to, from, and 
within the United States. The NRC has not initiated any rulemaking 
activities to address changes made by the IAEA regarding the 
transportation of excepted fissile materials. In order to maintain 
uniform treatment for shippers of excepted fissile materials, PHMSA is 
amending Sec.  171.23 to require that shipments of excepted fissile 
materials offered in accordance with the IAEA SSR-6 regulations must 
also conform to the requirements of Sec.  173.453.
Section 171.24
    Section 171.24 details additional requirements for the use of the 
ICAO TI. In this NPRM, PHMSA is proposing to amend the marking 
requirement for packages containing primary lithium batteries and cells 
that meet the exceptions in paragraph (d)(1)(ii). Packages meeting 
these exceptions currently are required to be marked with an indication 
that they contain lithium batteries, and that these lithium batteries 
are forbidden for transport aboard passenger aircraft. PHMSA is 
proposing to allow the message that these batteries are forbidden for 
transport aboard passenger aircraft to be expressed through the current 
marking or by using a CARGO AIRCRAFT ONLY label as shown in Sec.  
172.448.
Section 171.25
    Section 171.24 details additional requirements for the use of the 
IMDG Code. In this NPRM, PHMSA is proposing to amend the marking 
requirement for packages containing primary lithium batteries and cells 
that meet the exceptions in Sec.  173.185(c) in paragraph (b)(3). 
Packages meeting these exceptions currently are required to be marked 
with an indication that they contain lithium batteries, and that these 
lithium batteries are forbidden for transport aboard passenger 
aircraft. PHMSA is proposing to allow the message that these batteries 
are forbidden for transport aboard passenger aircraft to be expressed 
through the current marking or by using a CARGO AIRCRAFT ONLY label as 
shown in Sec.  172.448.

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 for 
paragraph (k) of this section.
    Paragraph (k) of Sec.  172.101 explains the purpose of column (10) 
of the HMT and prescribes the vessel stowage and segregation 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 amend this instructional text to note that the codes in 
column 10B address not only codes for stowage requirements, but also, 
in certain instances, handling requirements that need to be observed 
during loading of the hazardous materials. The IMO, in amendment 37-14 
of the IMDG Code, has split their stowage and segregation column (16) 
in the dangerous goods list into two columns and assigned codes to the 
existing stowage, handling, and segregation text. The new first column 
(16a) in the IMDG Code is entitled stowage and handling, and the second 
column (16b) is titled segregation. PHMSA is proposing to maintain the 
HMR's current column 10A and 10B system, with text in this section and 
Sec.  176.84 indicating that handling/loading of hazardous materials is 
also covered by certain codes in column 10B. See Section 176.84 other 
requirements for stowage, cargo handling, and segregation for cargo 
vessels and passenger vessels for a detailed discussion of proposed 
changes.
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
UN3507 Uranium hexafluoride, radioactive material, excepted

[[Page 50750]]

package, less than 0.1 kg per package, non-fissile or fissile-excepted

    This new HMT entry addresses small quantities of uranium 
hexafluoride having corrosive properties by assigning the material to 
Class 8 with a subsidiary risk of Class 7 since this would be more 
consistent with the general rule of classification of radioactive 
material in limited quantities possessing other hazards per Sec.  
173.423. Shipments must comply with new special provision 369 and 
requirements found in Sec.  173.420(d).

UN3508 Capacitor, asymmetric with an energy storage capacity greater 
than 0.3Wh

    This new HMT entry is intended to cover asymmetric capacitors with 
an energy storage capacity greater than 0.3 Wh. Asymmetric capacitors 
are assigned as a Class 9 miscellaneous hazardous.

UN3510 Adsorbed gas, flammable, n.o.s.
UN3511 Adsorbed gas, n.o.s.
UN3512 Adsorbed gas, toxic, n.o.s.
UN3513 Adsorbed gas, oxidizing, n.o.s.
UN3514 Adsorbed gas, toxic, flammable, n.o.s.
UN3515 Adsorbed gas, toxic, oxidizing, n.o.s.
UN3516 Adsorbed gas, toxic, corrosive, n.o.s.
UN3517 Adsorbed gas, toxic, flammable, corrosive, n.o.s.
UN3518 Adsorbed gas, toxic, oxidizing, corrosive, n.o.s.
UN3519 Boron trifluoride, adsorbed
UN3520 Chlorine, adsorbed
UN3521 Silicon tetrafluoride, adsorbed
UN3522 Arsine, adsorbed
UN3523 Germane, adsorbed
UN3524 Phosphorus pentafluoride, adsorbed
UN3525 Phosphine, adsorbed
UN3526 Hydrogen selenide, adsorbed

    The ``Adsorbed gas'' HMT entries are added to address shipments of 
gas, which when packaged for transport, are adsorbed onto a solid 
porous material in a pressure receptacle. Entries classified as 
Division 2.3 gases are forbidden for transport by aircraft.
    Duplicate entries for UN0214 Trinitrobenzene, dry or wetted with 
less than 30 percent water, by mass currently exist in the HMT; while 
the UN1354 entry has been inadvertently overwritten by one of these 
UN0214 entries in an unidentified previous rulemaking. PHMSA is 
proposing to remove one of the duplicate UN0214 entries, and to 
reinsert the correct UN1354 entry.
    During the course of reviewing Column 10B (Vessel stowage Other 
codes) for harmonization with changes made in the 37-14 IMDG Code, 
PHMSA noticed that the entry for UN3231 Self-reactive liquid type B, 
temperature controlled is not currently listed in the HMR. This is 
believed to be the result of an inadvertent deletion in an unidentified 
rulemaking. PHMSA is proposing to reinstate the HMT entry for UN3231.
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. The symbol ``I'' indicates these 
proper shipping names are appropriate for describing materials in 
international transportation, but that an alternate proper shipping 
name may be selected when only domestic transportation is involved.
    In this NPRM PHMSA is proposing to add international proper 
shipping names for ``Asbestos, amphibole (amosite, tremolite, 
actinolite, anthophyllite, crocidolite)'' and ``Asbestos, chrysotile'', 
and remove shipping descriptions for Blue, Brown, and White Asbestos. 
These new international proper shipping names for ``Asbestos, 
amphibole'' and ``Asbestos, chrysotile'' are proposed to have an ``I'' 
assigned in column one. PHMSA is also proposing to assign a ``G'' to 
the ``Asbestos, amphibole'' entry. The ``G'' indicates that the 
technical name(s) of the hazardous material must be entered in 
parentheses, in association with the basic description. In the case of 
this proposed proper shipping name, the technical name shown should be 
selected from the list of five different minerals (amosite, tremolite, 
actinolite, anthophyllite, crocidolite) indicated in italics after the 
proper shipping name. See the amendments to column (2) of the HMT for 
additional discussion regarding the revision of the proper shipping 
names for these entries.
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.
    The proper shipping name for ``UN0222, Ammonium nitrate, with more 
than 0.2 percent combustible substances, including any organic 
substance calculated as carbon, to the exclusion of any other added 
substance'' is amended by removing the italicized text and placing the 
text into the new special provision 370.
    The proper shipping name for ``UN1942, Ammonium nitrate, with not 
more than 0.2% combustible materials, including any organic substance, 
calculated as carbon to the exclusion of any other added substance'' is 
amended by replacing the word ``materials'' in italicized text with 
``substances'' and the comma following ``substance'' is placed after 
the word ``carbon.'' Due to the present placement of the comma in the 
description for the two ammonium nitrate entries, the 0.2% combustible 
materials/substances are measured differently. This amendment ensures 
that the 0.2% combustible level is calculated as carbon in the case of 
organic substances.
    Two new proper shipping names ``Asbestos, amphibole (amosite, 
tremolite, actinolite, anthophyllite, crocidolite)'' and ``Asbestos, 
chrysotile'' are proposed to be assigned to identification numbers 
UN2212 and UN2590, respectively. These new proper shipping names more 
appropriately describe the material than the present ``UN2212, Blue 
asbestos (Crocidolite) or Brown asbestos (amosite, mysorite)'' and 
``UN2590, White asbestos (chrysotile, actinolite, anthophyllite, 
tremolite).'' In the scientific community, Asbestos is divided into two 
chemical group names, ``Amphiboles'' and ``Chrysotile''. The amphibole 
group includes five different minerals (amosite, tremolite, actinolite, 
anthophyllite, crocidolite). The chrysotile group includes only the 
mineral chrysotile.
    The proper shipping name for ``UN3499, Capacitor, electric double 
layer (with an energy storage capacity greater than 0.3 Wh)'' is 
amended by placing the phrase ``electric double layer'' in Roman type. 
This amendment is necessary to differentiate this HMT entry from the 
new HMT entry, Capacitor, asymmetric.
    A new proper shipping name ``Safety devices, electrically 
initiated'' is proposed to be assigned to identification number UN3268. 
Current proper shipping names assigned to UN3268 are ``Air bag 
inflators, or Air bag modules, or Seat-belt pretensioners.'' The 
proposed proper shipping name more appropriately describes materials 
authorized under this HMT entry in conjunction with the proposed 
revision to special provision 160 to include a number of automotive 
industry life-saving appliances that are actuated by the electric 
signal of the crash sensor.

[[Page 50751]]

    A new proper shipping name ``Safety devices, pyrotechnic'' is 
proposed to be assigned to identification number UN0503. The current 
proper shipping names assigned to UN0503 are ``Air bag inflators, or 
Air bag modules, or Seat-belt pretensioners.'' The proposed proper 
shipping name more appropriately describes Class 1 materials authorized 
under this HMT entry.
    The proper shipping name for ``UN1082, Trifluorochloroethylene, 
stabilized'' is amended by adding ``Refrigerant gas R 1113'' as an 
alternative proper shipping name for consistency with the Dangerous 
Goods Lists of the various international standards and the HMT of the 
HMR. The proposed proper shipping name for UN1082 is

``Trifluorochloroethylene, stabilized or Refrigerant gas R 1113''
Amendments to Column (5) Packing Group
    Section 172.101(f) describes Column (5) of the HMT and the 
designation of the packing group(s) assigned to each proper shipping 
name.
    For the entries ``UN3316, Chemical kits'' and ``UN3316, First aid 
kits'' the Packing Groups II and III designations are proposed. The 
assignment of packing groups to these entries are not a new 
requirement; however, including packing group assignments in the HMT 
will ensure that shippers are aware that the most stringent packing 
group must be assigned to any individual substance in the kit in 
accordance 173.161(a)(2).
    The HMT entries for several articles are revised to remove packing 
group assignments. For articles, the packing group does not relate to 
the degree of hazard posed by the material but rather is assigned 
generically to the article. There is limited value in requiring an 
indication of the packing group in association with the shipment. 
Currently and without specific rationale, some articles are assigned 
packing groups while others are not. This proposed change provides a 
level of consistency for all articles specifically listed in the HMT. 
In this NPRM, PHMSA is proposing to remove packing group assignments 
from the following HMT entries:

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

Amendments to the Column (7) Special Provisions
    Section 172.101(h) describes Column (7) of the HMT and Sec.  
172.102(c) the special provisions assigned to specific entries in the 
HMT. The particular modifications to the entries in the HMT are 
discussed below. See Section 172.102 special provisions for a detailed 
discussion of the proposed additions, revisions, and deletions to the 
special provisions addressed in this NPRM.
    In this NPRM, special provision 134 is added to the HMT entry 
``UN3072, Life-saving appliances, not self-inflating containing 
dangerous goods as equipment.'' The addition of this special provision 
will clarify that equipment containing only lithium batteries must be 
consigned under the entries ``Lithium batteries contained in 
equipment'' or ``Lithium batteries packed with equipment,'' as 
appropriate.
    Several HMT entries are revised to include new special provision 
367. Special provision 367 authorizes the use of the ``Paint related 
material'' entries for consignments of packages containing ``Paint'' 
and ``Paint related material'' in the same package. This special 
provision also authorizes the proper shipping name ``Printing ink 
related material'' for consignments of packages containing ``Printing 
Ink'' and ``Printing ink related material'' in the same package.
    In this NPRM, new special provision 367 is proposed to be assigned 
to the following entries:

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

Printing ink, flammable or Printing ink related material          UN1210
 (including printing ink thinning or reducing compound),
 flammable..............................................
------------------------------------------------------------------------

    In this NPRM, we propose to add new special provision 368 to the 
HMT entry ``UN2910, Radioactive material, excepted package-limited 
quantity of material.''

[[Page 50752]]

    In this NPRM, new special provision 369 is proposed to be assigned 
to the new HMT entry ``UN3507, Uranium hexafluoride, radioactive 
material, excepted package, less than 0.1 kg per package, non-fissile 
or fissile-excepted.''
    In this NPRM, new special provision 370 is proposed to be assigned 
to the HMT entry ``UN0222, Ammonium nitrate.'' This special provision 
contains qualifying language that previous to this NPRM, was part of 
the proper shipping name for UN0222.
    In this NPRM, new special provision 371 is proposed to be assigned 
to the HMT entry ``UN3164, Articles, pressurized pneumatic or hydraulic 
containing non-flammable gas.''
    In this NPRM, new special provision 375 is proposed to be assigned 
to the HMT entries ``UN3077, Environmentally hazardous substance, 
solid, n.o.s.'' and ``UN3077, Environmentally hazardous substance, 
liquid, n.o.s.''
    In this NPRM, for the HMT Packing Group III entry ``UN3089, Metal 
powders, flammable, n.o.s.'' special provision IB6 is replaced with IB8 
and special provisions IP2, and IP4 are added. IB8 is presently 
assigned to the Packing Group II entry, therefore, fiberboard, wooden 
and flexible IBCs are allowed for the Packing Group II materials, but 
are forbidden for the less dangerous Packing Group III substance. These 
proposed revisions will correct the inconsistency.
    In this NPRM, new special provision A61 is proposed to be assigned 
to the HMT entries ``UN 3107, Organic peroxide type E, liquid'' and 
``UN 3109, Organic peroxide type F, liquid''.
    Several HMT entries are revised to include new portable tank 
special provision TP47. Special provision TP47 indicates that the 2.5 
year internal portable tank examination may be waived or substituted by 
other test methods or inspection procedures specified by the competent 
authority or its authorized body, provided that the portable tank is 
dedicated to the transport of the organometallic substances to which 
this tank special provision is assigned. However, this examination is 
required when the conditions of Sec.  180.605(f) are met.
    In this NPRM, new special provision TP47 is proposed to be assigned 
to the following entries:

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

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

    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)). The indication of ``forbidden'' means the material may 
not be offered for transportation or transported in the applicable mode 
of transport.
    For the entry ``UN3497, Krill meal'' quantity limits of 15 kg and 
50 kg for PG II, and 25 kg and 100 kg for PG III, are proposed for 
columns (9A) and (9B) respectively. 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 
TI.
    At the 24th meeting the ICAO DGP, it was agreed to incorporate 
certain UN numbers contained in the UN Model Regulations, but not 
currently listed in the ICAO TI. For the entry ``UN2216, Fish meal, 
stabilized or Fish scrap, stabilized,'' the panel determined that it 
should be forbidden for transport on both cargo and passenger aircraft. 
Under the HMR, this entry is assigned a ``W'' in Column (1) meaning 
that the material is only subject to the requirements when offered or 
intended for transport by vessel. Because of this discrepancy, in this 
NPRM, PHMSA is soliciting public comment on any potential action to 
align with the ICAO TI (including potentially adding ``A'' to column 
one and forbidding this entry aboard both cargo and passenger aircraft) 
and what potential benefit or burden a change to these quantity limits 
for UN2216 could potentially impose upon shippers and air operators.
    Amendments to the Column (10) vessel stowage requirements.
    Vessel stowage location (10B).
    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.
    The IMO, in amendment 37-14 of the IMDG Code, split their stowage 
and segregation column (16) in the dangerous goods list into two 
columns and assigned codes to the existing stowage, handling, and 
segregation text. The new first column (16a) in the IMDG Code is titled 
stowage and handling, and the second column (16b) is titled 
segregation. PHMSA is proposing to maintain the HMT's current column 
10A and 10B, while also harmonizing our vessel stowage codes in columns 
10A and 10B as closely as possible with those in amendment 37-14 of the 
IMDG Code. There are several instances where PHMSA is proposing to 
maintain additional codes (see UN numbers 0019, 0020, 0021, 0301, 0303, 
1017, 1131, 1389, 1392, 1420, 1422, 1780, 1942, 1950, 2679, 2912, 3015, 
3071, 3101-3106, 3108-3110, 3242, 3323, and 3497) that vary from IMDG 
Code stowage and segregation requirements. These additional stowage and 
segregation provisions vary by UN number, but are considered additional 
precautions deemed necessary to ensure the safe transport of these 
commodities during transportation by vessel. PHMSA welcomes comments on 
the continued need and or the impact of maintaining this limited number 
of domestic variations from the international stowage, handling, and 
segregation requirements.
    During the preparation of this NPRM, PHMSA and the United States 
Coast Guard conducted an extensive review of all HMT entries to verify 
that domestic entries correspond as closely as possible with the 
provisions found in the IMDG Code. PHMSA is proposing numerous changes 
to the codes found in the HMT's column 10B [Other provisions] as a 
result of this review. The majority

[[Page 50753]]

of the changes are a result of work done at the IMO to eliminate 
duplicate and unnecessary provisions. Some of the proposed changes to 
column 10B are proposed to harmonize existing differences in stowage, 
handling, and segregation provisions between the HMR and the IMDG Code. 
Recognizing that there are both shippers and carriers that only offer 
hazardous materials by vessel domestically, PHMSA seeks comments on the 
costs and benefits to these domestic shippers and carriers of 
harmonizing the stowage provisions of the HMR with the provisions of 
the IMDG Code as proposed in this NPRM. PHMSA also solicits comments on 
the costs and benefits were we to maintain domestic stowage differences 
within the HMR. A table of proposed changes, listed in alphabetical 
order, showing the proper shipping name, UN identification number, any 
stowage codes proposed for removal, and any stowage codes proposed for 
addition is provided below. If a column is blank, no changes are 
proposed. The meaning of the codes in column 10B can be found either in 
Sec.  176.84 or are listed in the Sec.  176.84 Section-by-Section 
change portion of this NPRM.

Appendix B to Sec.  172.101
    Appendix B to Sec.  172.101 lists Marine Pollutants regulated under 
the HMR. In this NPRM, PHMSA is proposing to revise the List of Marine 
Pollutants by adding sixty-two new entries consistent with the IMDG 
Code. These changes are proposed to include those substances that, by 
virtue of meeting the Group of Experts on the Scientific Aspects of 
Marine Environmental Protection (GESAMP) defining criteria for marine 
pollutants, were either assigned a ``P'' in the dangerous goods list or 
identified in the alphabetical index to amendment 37-14 of the IMDG 
Code. The entry ``Chlorotoluenes (meta-;para-)'' would be removed based 
on its removal from the IMDG Code.
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 Sec.  172.102, special provisions:
Special Provision 28
    Special provision 28 states that the dihydrated sodium salt of 
dichloroisocyanuric acid is not subject to the HMR. In this NPRM, PHMSA 
proposes to revise special provision 28 to convey that the dihydrated 
sodium salt of dichloroisocyanuric acid does not meet the definition of 
a Division 5.1 (oxidizer) and is not subject to the requirements of the 
subchapter unless it meets the criteria for inclusion in another Class 
or Division, such as Class 9, environmentally hazardous substance. Some 
formulations of the dihydrated sodium salt of dichloroisocyanuric acid 
meet the criteria for classification as an environmentally hazardous 
substance.
Special Provision 52
    Special provision 52 authorizes use of the HMT entry ``UN2067, 
Ammonium nitrate based fertilizer'' for substances that do not exhibit 
explosive properties of Class 1 when tested in accordance with Test 
Series 1 and 2 of the UN Manual of Tests and Criteria, Part I. In this 
NPRM, PHMSA proposes to revise special provision 52 by removing the 
requirement to test in accordance with Test Series 1 because Test 
Series 2 determines whether such properties are indeed those of Class 
1, not Test Series 1.
Special Provision 147
    This special provision describes the composition of the material 
for which the use of the HMT entry ``UN3375, Ammonium nitrate emulsion 
or Ammonium nitrate suspension or Ammonium nitrate gel, intermediate 
for blasting explosives'' is authorized and prohibits the material from 
being classified and transported unless approved by the Associate 
Administrator. Special provision 147 requires that these substances 
must satisfactorily pass Test Series 8 of the UN Manual of Tests and 
Criteria, Part I, Section 18. Test Series 8 contains four test types. 
Tests 8(a), (b) and (c) are used for classification purposes while Test 
8(d) is used to assess suitability for transport in portable tanks. The 
use of this entry (UN 3375) therefore requires only that Tests 8(a), 
(b) and (c) are satisfactorily passed. In this NPRM, PHMSA is proposing 
to revise special provision 147 by clarifying that Tests 8(a), (b) and 
(c), not the entire Test Series 8, are required for use in 
classification and subsequent approval by the Associate Administrator.
Special Provision 160
    Special provision 160 is presently assigned to ``UN3268, Air bag 
inflators, or Air bag modules, or Seat-belt pretensioners'' in Class 9. 
Special provision 160 includes the requirement that air bag inflators 
and modules must be tested in accordance with Test series 6 (c) of Part 
I of the UN Manual of Tests and Criteria. In this NPRM, PHMSA is 
proposing to revise special provision 160 in conjunction with revising 
the proper shipping name for UN3268 to ``Safety devices, electrically 
initiated.'' The entry is revised to clarify that it applies to safety 
devices used in vehicles including vessels and aircraft, and 
pyromechanical devices that are added to the list of authorized 
devices. The development of safety products has seen significant 
progress since the introduction of UN3268 and the range of current 
products extends beyond what can presently be assigned to UN3268. Some 
of the newer safety products include elements that are actuated by the 
electrical signal of the crash sensor (e.g. pyromechanical devices). 
Examples include: Devices that interrupt the electrical connection in 
case of emergency by disconnecting the main power cable in the vehicle 
from the battery to prevent short circuit and consequentially minimize 
the risk of fire in the vehicle; and actuators which are used for 
active headrests or for pedestrian protection to release special hinges 
of the engine hood. In addition, PHMSA is proposing to clarify that 
this entry does not apply to life saving appliances described in Sec.  
173.219 (UN Nos. 2990 and 3072).
Special Provision 161
    Special provision 161 required that for domestic transportation the 
alternate shipping description ``Articles, pyrotechnic for technical 
purposes'' be used to describe air bag inflators, air bag modules and 
seat-belt pretensioners (UN0503) meeting the criteria for a Division 
1.4G explosive. This was done to ensure a different shipping name was 
used to describe these articles to differentiate them from air bag 
inflators, air bag modules and seat-belt pretensioners (UN3268) in 
Class 9. In this NPRM, PHMSA proposes, consistent with the UN Model 
Regulations, to adopt new proper shipping names for these items, 
``Safety devices'' (UN3268) for these articles

[[Page 50758]]

assigned to Class 9, and ``Safety Devices, pyrotechnic'' (UN0503) for 
these articles assigned to Division 1.4G. Since the proper shipping 
names for these items would no longer the same, there would be no need 
to use a different proper shipping name for these articles assigned to 
Division 1.4G. Therefore the need for this special provision would be 
obsolete and we propose to delete it from the regulations and to delete 
its reference from the UN0503 entry in the HMT. Under this proposed 
revision, for domestic transportation, air bag inflators, air bag 
modules and seat-belt pretensioners (UN0503) meeting the criteria for a 
Division 1.4G explosive, that are currently described as ``Articles, 
pyrotechnic for technical purposes'' would be described as ``Safety 
devices, pyrotechnic'' (UN0503).
Special Provision 238
    Special provision 238 addresses the shipment of neutron radiation 
detectors. In this NPRM, PHMSA proposes to revise special provision 238 
to align with the UN Model Regulations special provision 373 by 
expanding the transport conditions for neutron radiation detectors and 
radiation detection systems containing such detectors. Paragraph a. is 
restructured into: (a)(1), General transport requirements; (a)(2), 
requirements for radiation detectors transported as individual 
components; and (a)(3), requirements for completed neutron radiation 
detection systems containing detectors. Consistent with the UN Model 
Regulations, PHMSA is proposing the following revisions to the 
transport conditions: [1] In (a)(1), increase the total amount of gas 
authorized per detector from 12.8 grams to 13 grams; clarify that the 
minimum burst pressure is demonstrated by design type qualification 
testing; and add a new leaktightness standard; [2] in (a)(2), clarify 
that in addition to being packed in a strong outer package, that the 
completed package must be capable of withstanding a drop of 1.8 meters 
(6-foot) without leakage of gas contents; and increase the total amount 
of gas from all detectors per outer packaging from 51.2 grams to 52 
grams; and [3], in (a)(3), add a new requirement that for completed 
neutron radiation detection systems, the detectors must be contained in 
a strong sealed outer casing; and add a new requirement that the 
completed system must be capable of withstanding a 1.8 meter (6-foot) 
drop test without leakage unless a system's outer casing affords 
equivalent protection.
Special Provision 342
    This special provision, assigned to ``UN1040, Ethylene oxide or 
Ethylene oxide with nitrogen'' allows sterilization devices containing 
ethylene oxide, conforming to the conditions in the special provision, 
and packaged in accordance with Sec.  173.4a of the HMR to be offered 
for transportation and transported by all modes even though Column (9A) 
of the Sec.  172.101 HMT lists the material as forbidden by passenger 
aircraft.
    Consistent with the ICAO TI, in this NPRM, PHMSA is proposing to 
further clarify that irrespective of both Columns (9A) and (9B) of the 
Sec.  172.101 HMT listing the material as forbidden, ethylene oxide 
conforming to the conditions in the special provision is eligible for 
air transport. Specifically, we are proposing to supplement the 
language in this special provision ``irrespective of the restriction of 
Sec.  173.4a(b)'' with ``and the indication of ``forbidden'' in columns 
(9A) and (9B) of the Sec.  172.101 table.''
Special Provision 362
    Special provision 362 specifies when a material can be considered a 
chemical under pressure. Specifically, the special provision states 
that classification of these materials is to be based on hazard 
characteristics of the components in the propellant, the liquid, or the 
solid forms. In this NPRM, PHMSA proposes to revise special provision 
362 by adding a new paragraph (f) to clarify that chemicals under 
pressure containing components forbidden for transport on both 
passenger and cargo aircraft must not be transported by air.
Special Provision 367
    A new special provision 367 is proposed to clarify that the proper 
shipping name ``Paint related material'' or ``Printing ink related 
material'' may be used for consignments of packages containing both 
``Paint'' and ``Paint related material'' or ``Printing Ink'' and 
``Printing ink related material'' in the same package and sharing the 
same identification number (UN 1210, UN 1263, UN 3066, UN 3469, or UN 
3470). For example, ``UN1263, Paint including paint, lacquer, enamel, 
stain, shellac solutions, varnish, polish, liquid filler, and liquid 
lacquer base'' and ``UN1263, Paint related material'' contained in the 
same package, may be consigned under the entry ``UN1263, Paint related 
material including paint thinning, drying, removing, or reducing 
compound.'' Paint mainly consists of resin, pigment and solvent. 
Thinning compound consists of solvent as well. Thus under the same UN 
entry, there is no difference between ``Paint'' and ``Paint related 
material'' with regard to transport requirements.
Special Provision 368
    In this NPRM, PHMSA proposes adding new special provision 368 and 
assigning it to ``UN2910, Radioactive material, excepted package-
limited quantity of material'' to clarify that in the case of non-
fissile or fissile-excepted uranium hexafluoride, the material must be 
classified under UN3507 or UN2978.''
Special Provision 369
    The 18th Revised Edition of the UN Model Regulations has adopted a 
new proper shipping name of ``UN3507, Uranium hexafluoride, radioactive 
material, excepted package, less than 0.1 kg per package, non-fissile 
or fissile-excepted'', to address small quantities of uranium 
hexafluoride containing corrosive properties, thus a new special 
provision is necessary in the HMR. In this NPRM, PHMSA proposes the 
assignment of special provision 369 to UN3507 to specify a primary 
hazard of Class 8 with subsidiary risk of Class 7, subject to certain 
conditions. The provisions in special provision 369 relating to 
conditions required when it is evident that packages have leaked are 
consistent with language proposed for inclusion in Sec.  173.443(e) in 
HM-250 [Docket No. PHMSA-2009-0063]. PHMSA notes that if the proposed 
addition of these provisions in Sec.  173.443(e) occurs, the portion of 
the text proposed in this NPRM referring to leaking packages may be 
replaced with a reference to Sec.  173.443(e).
Special Provision 370
    In this NPRM, PHMSA proposes adding new special provision 370 and 
assigning it to the revised HMT entry ``UN0222, Ammonium Nitrate.'' As 
a result of the comma placement in the descriptions for the two 
ammonium nitrate entries, UN1942 and UN0222, the manner in which the 
0.2% combustible materials/substances level is calculated would lead to 
different analyses and different, non-comparable results. In 
conjunction with revising the proper shipping name for UN0222 by 
removing the qualifying text, in this NPRM, PHMSA is proposing a new 
special provision assigned to UN0222 to include the qualifying text 
previously attached to the proper shipping name and further clarify the 
criteria for use of this entry by stipulating the following conditions: 
(1) Ammonium nitrate with more than 0.2% combustible substances, 
including any organic

[[Page 50759]]

substance calculated as carbon, to the exclusion of any added 
substance; or (2) ammonium nitrate with not more than 0.2% combustible 
substances, including any organic substance calculated as carbon, to 
the exclusion of any added substance, that gives a positive result when 
tested in accordance with Test Series 2 of the UN Manual of Tests and 
Criteria, Part I.
Special Provision 371
    In this NPRM PHMSA proposes adding a new special provision 371 and 
assigning it to ``UN3164, Articles, pressurized pneumatic or hydraulic 
containing non-flammable gas.'' This special provision sets forth the 
requirements for confetti-shooters pressurized with gas instead of 
pyrotechnics. The shooter consists in principle, of a jacket of 
cardboard, the pressurized receptacle filled with compressed air or 
nitrogen, a lock mechanism made of plastics, a plug of rubber and a 
metal cap for closing the receptacle and different types of confetti. 
By turning a ring, or the bottom part of the shooter, a mechanism is 
unlocked and the pressurized gas is discharged so that the confetti is 
shot away for a few meters. This type of shooter does not contain any 
amount of explosives and therefore cannot be assigned to Class 1, and 
does not meet the requirements for gas cartridges or small pressure 
receptacles. The requirements set forth in the special provision ensure 
the same level of safety as for confetti-shooters with pyrotechnics.
Special Provision 372
    In this NPRM, PHMSA proposes adding new special provision 372 and 
assigning it to the new HMT entry ``UN3508, Capacitor, asymmetric.'' 
This special provision states that this entry applies to asymmetric 
capacitors with an energy storage capacity greater than 0.3 watt hours 
(Wh) and that asymmetric capacitors with an energy storage capacity of 
0.3 Wh or less are not subject to the requirements of this subchapter. 
This special provision also provides that nickel-carbon asymmetric 
capacitors containing Class 8 alkaline electrolytes must be transported 
as UN 2795, Batteries, wet, filled with alkali, electric storage.
Special Provision A60
    Special provision A60 permits ``UN2014, Hydrogen peroxide, aqueous 
solution,'' to be transported in excepted quantities. The special 
provision authorizes packagings to include a vent to permit the slow 
escape of gas (i.e. not more than 0.1 mL/hour per 30 mL inner packaging 
at 20 [deg]C (68[emsp14][deg]F) produced from gradual decomposition. As 
venting is permitted, the requirements of Sec. Sec.  173.24(g)(1) and 
173.27(c) are impracticable and should not apply. To address the issue, 
the ICAO DGP adopted a proposal to clarify these general requirements 
prohibiting venting should not be applicable. In this NPRM, we are 
proposing to harmonize with the ICAO TI with regard to waiving the 
general requirements of Sec. Sec.  173.24(g)(1) and 173.27(c). Special 
provision A60 is revised accordingly.
Special Provision A61
    In this NPRM, PHMSA proposes adding new special provision A61 and 
assigning it to the to the HMT entries ``UN 3107, Organic peroxide type 
E, liquid'' and ``UN 3109, Organic peroxide type F, liquid.'' PHMSA 
proposes to align with Packing Instruction 570 of the ICAO TI to allow 
for limited venting of oxygen in the case of specialized peroxyacetic 
acid packagings when transported by cargo aircraft provided the 
packaging requirements of this special provision are met. It was 
reported to the ICAO DGP that peroxyacetic acid was commonly used as a 
sterilizer for health care purposes and that there is a need to 
transport the material by air for use in sterilizing medical equipment 
using custom packagings. The basis for the requirements that these 
specialized packagings must meet originated from exemptions to permit 
the transport of this substance in small containers approved by 
appropriate national authorities in four States. The inclusion of this 
new special provision will eliminate the need for these exemptions and 
facilitate international transport.
IBC Codes and IP Codes
    The introductory paragraph (c)(4) states that packagings are 
authorized for the Packing Group III entries of specific proper 
shipping names when either Special Provision IB3 or IB8 is assigned to 
that entry in the Sec.  172.101 Table. When no IB code is assigned in 
the Sec.  172.101 Table for a specific proper shipping name, or in 
Sec.  173.225(e) Organic Peroxide Table for Type F organic peroxides, 
use of an IBC or Large Packaging for the material may be authorized 
when approved by the Associate Administrator.
    In this NPRM, PHMSA proposes to revise the introductory paragraph 
(c)(4) by adding a reference to Sec.  173.185, preceding the reference 
to Sec.  173.225(e), thereby authorizing the use of Large Packagings 
for lithium batteries without assigning IB3 or IB8 to the corresponding 
entries in the Sec.  172.101 Table. See Section 173.185 Lithium 
batteries for a detailed discussion of the proposed a use of rigid 
large packagings for lithium batteries.
    In two final rules published in the Federal Register on January 19, 
2011 (76 FR 3308; HM-215K) and January 7, 2013 (78 FR 988; HM-215L) the 
Table 1 (IBC Codes) in paragraph (c)(4) were editorially revised to 
remove UN Specifications 31A, 31B, 31N, 31H1, 31H2, 31HZ1, and 31HZ2 
from IBC Codes IB4 through IB8. The revisions were 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, 31N, 31H1, 
31H2, 31HZ1, and 31HZ2 are authorized for transportation of liquids in 
IBC Codes IB1 through IB3 and are assigned to liquid materials only. 
Information presented to the UN Committee of Experts on the Transport 
of Dangerous Goods (UNCOE) in this last biennium indicated that the 
removal of the above UN Specifications from IBC Codes IB4 through IB8 
has created a problem. Prior to implementation of these revisions, 
certain liquid IBC types were used to transport powdery solids and 
solids that become liquid under conditions of transport. These solids 
may be loaded and unloaded from the IBC in liquid form raising the 
question of whether the remaining IBC's, which are intended for gravity 
or pressure discharge, are appropriate. The UN sub-committee adopted a 
proposal to reinstate the IBC's that were previously authorized. In 
this NPRM, we are proposing to harmonize with the UN Model Regulations 
by revising the IBC Codes IB4 through IB8 in paragraph (c)(4), the 
Table 1 (IBC Codes) to reinstate IBC's previously authorized.
    A new IP Code 16 is added and assigned to UN3375. Consistent with 
international regulations, this special provision would authorize 
require IBCs of type 31A and 31N if approved by the Associate 
Administrator.
Special Provision TP47
    In this NPRM, PHMSA proposes adding new special provision TP47 and 
assigning it to the organometallic substance HMT entries UN3393 through 
UN3399. The special provision waives the 2.5 year internal inspection 
for portable tanks used for the transport of liquid and solid 
organometallic substances provided that the portable tank remains in 
the dedicated service of transporting organometallic substances. 
However, all other required 2.5 year inspections and tests would still 
be

[[Page 50760]]

performed, as well as the full 5 year periodic test and inspection, 
which would include an internal inspection.
    This special provision is added for the following reasons. Before 
an internal inspection can be performed, the tank must be cleaned and 
purged. In this process, it is difficult to ensure that all water or 
other impurities or contaminants introduced during the cleaning are 
fully removed before organometallic substances are again introduced 
into the tank potentially resulting in a dangerous reaction or have an 
effect on the purity of the product. Since these organometallic 
substances are fully compatible with, and, in particular, are not 
corrosive to the materials of construction used in such tanks, the 
likelihood that an internal inspection will reveal any corrosion, 
pitting or other deterioration of the tank is unlikely. In order to 
increase safety and avoid the risk of a dangerous reaction or product 
contamination the 2.5 year internal inspection is waived, provided the 
portable tank remains in the dedicated service of transporting 
organometallic substances and the tank does exhibit damaged or corroded 
areas, or leakage, or other conditions that indicate a deficiency in 
accordance with Sec.  180.605(f).
Section 172.315
    To promote the uniformity of markings, the UN Model Regulations 
have adopted revisions to clarify and standardize the specifications 
for limited quantity marking, including the air limited quantity 
marking. In this NPRM, PHMSA is proposing to revise the specifications 
for the limited quantity markings prescribed in Sec.  172.315(a)(2) and 
(b)(2) to be consistent with the revised specifications for these 
markings in the UN Model Regulations. Also consistent with the UN Model 
Regulations, we propose to allow manufacturers and printers necessary 
time to retool to produce markings that conform to the revised 
specifications, and to allow for the depletion of supplies of existing 
markings. PHMSA proposes a transitional period to authorize a limited 
quantity marking that is in conformance with the requirements of the 
regulations in effect on October 1, 2012, to be used until December 31, 
2016.
Section 172.317
    To promote the uniformity of the ``Keep Away From Heat'' handling 
mark throughout the international transportation community, revisions 
have been adopted in the ICAO Technical Instructions to clarify and 
standardize the specifications for this hazard communications element. 
In this NPRM, PHMSA is proposing to revise the specifications for the 
``Keep Away From Heat'' handling mark prescribed in Sec.  172.317(b) to 
be consistent with the revised specifications for this marking in the 
ICAO TI. Also, we propose to allow manufacturers and printers necessary 
time to retool to produce markings that conform to the revised 
specifications, and to allow for the depletion of supplies of existing 
markings. Thus we propose a transitional period to authorize a ``Keep 
Away From Heat'' handling mark that is in conformance with the 
requirements of the regulations in effect on October 1, 2012, to be 
used until December 31, 2016.
Section 172.322
    In this NPRM, PHMSA is proposing to clarify in Sec.  172.322(a)(2) 
and (b), that the marking requirements for marine pollutants are 
required unless otherwise provided for in the regulations.
    In Sec.  172.322 paragraph (e) PHMSA is proposing to delete the 
obsolete date of January 14, 2010 for the requirements for the marine 
pollutant mark.
    To promote the uniformity of the marine pollutant mark throughout 
the international transportation community, the UN Model Regulations 
have adopted revisions to clarify and standardize the specifications 
for this hazard communications element. In this NPRM, PHMSA is 
proposing to revise the specifications for the marine pollutant mark 
prescribed in Sec.  172.322(e) to be consistent with the revised 
specifications for this marking in the UN Model Regulations. Also, to 
allow manufacturers and printers necessary time to retool to produce 
markings that conform to the revised specifications, and to allow for 
the depletion of supplies of existing markings, we propose a 
transitional period to authorize a marine pollutant mark that is in 
conformance with the requirements of the regulations in effect on 
October 1, 2012, to be used until December 31, 2016.
Section 172.327
    To promote the uniformity of markings, in this NPRM, PHMSA is 
proposing to revise and clarify the specifications for the ``petroleum 
sour crude oil'' mark prescribed in Sec.  172.327(a) to be consistent 
with the revised specifications for markings in the UN Model 
Regulations. Also, to allow manufacturers and printers necessary time 
to retool to produce markings that conform to the revised 
specifications, and to allow for the depletion of supplies of existing 
markings, we propose a transitional period to authorize a ``petroleum 
sour crude oil'' mark that is in conformance with the requirements of 
the regulations in effect on October 1, 2012, to be used until December 
31, 2016.
Section 172.407
    To promote the uniformity of hazard communications labels 
throughout the international transportation community, revisions have 
been adopted in the UN Model Regulations to clarify and standardize the 
specifications for labels. In this NPRM, PHMSA is proposing to revise 
the specifications for labels prescribed in Sec.  172.407(a) to be 
consistent with the revised specifications for labels in the UN Model 
Regulations. In addition, PHMSA is proposing to revise the (d)(2)(iii) 
that provides a color alternative for the symbol on the ORGANIC 
PEROXIDE LABEL to be consistent with the UN Model Regulations. Also to 
be consistent with the UN Model Regulations, and to allow manufacturers 
and printers necessary time to retool to produce labels that conform to 
the revised specifications, and to allow for the depletion of supplies 
of existing labels, we propose a transitional period to authorize a 
label that is in conformance with the requirements of the regulations 
in effect on October 1, 2012, to be used until December 31, 2016.
    Finally, PHMSA is proposing to add paragraph (d)(2)(iv) to permit, 
consistent with the UN Model Regulations, a FLAMMABLE GAS label to be 
displayed on cylinders and gas cartridges for liquefied petroleum 
gases, where the symbol may be shown in the background color of the 
receptacle if adequate contrast is provided.
Section 172.512
    The placarding requirements for freight containers and aircraft 
unit load devices are described in Sec.  172.512. The reference in 
Sec.  172.512(a)(3) to part 7; chapter 2, section 2.7 of the ICAO TI in 
this paragraph is inaccurate. This reference became inaccurate in the 
2013-2014 Edition of the ICAO TI where the ICAO DGP re-designated part 
7; chapter 2; section 2.6 as a new requirement for visibility of 
labels, moving all subsequent sections up. Part 7; chapter 2, section 
2.7 of the ICAO TI now refers to replacement of labels, whereas section 
2.8 refers to identification of unit load devices containing dangerous 
goods. PHMSA is revising this paragraph for the correct

[[Page 50761]]

reference to cite part 7; chapter 2, section 2.8.
Section 172.519
    To promote the uniformity of hazard communications placards 
throughout the international transportation community, revisions have 
been adopted in the UN Model Regulations have adopted revisions to 
clarify and standardize the specifications for placards. In this NPRM, 
PHMSA is proposing to revise the specifications for placards prescribed 
in Sec.  172.519(c) to be consistent with the revised specifications 
for labels in the UN Model Regulations. Additionally, to allow 
manufacturers and printers necessary time to retool to produce placards 
that conform to the revised specifications, and to allow for the 
depletion of supplies of existing placards, a transitional period is 
proposed. This transitional period would authorize a placard that is in 
conformance with the requirements of the regulations in effect on 
October 1, 2012, to be used until December 31, 2016. Finally, PHMSA 
realizes that in domestic transportation, numerous placards of a semi-
permanent nature are in service. PHMSA is proposing that for domestic 
transportation, a placard manufactured prior to January 1, 2017, in 
conformance with the requirements of the regulations in effect on 
October 1, 2012, may continue in service until the end of its useful 
life provided the color tolerances are maintained and are in accordance 
with the display requirements of the subchapter.

Part 173

Section 173.2a
    Section 173.2a outlines classification requirements for materials 
having more than one hazard. In this NPRM, PHMSA is proposing to amend 
paragraph (a)(1) to note that shipments of uranium hexafluoride, 
radioactive material, excepted package, less than 0.1 kg per package 
are not required to apply the radioactive hazard as the primary hazard. 
This change is being proposed to incorporate the transportation 
provisions for excepted packages of uranium hexafluoride adopted in the 
18th Revised Edition of the UN Model Regulations, the IMDG Code and the 
ICAO TI.
Section 173.3
    To promote the uniformity of hazard communications markings 
throughout the international transportation community, the UN Model 
Regulations have adopted revisions to clarify and standardize the 
specifications for placards. In this NPRM, PHMSA is proposing to revise 
the specifications for markings for salvage packagings prescribed in 
Sec.  173.3(c)(3); salvage cylinders prescribed in Sec.  173.3(d)(3); 
and to prescribe requirements for the marking of the proposed large 
salvage packaging in Sec.  173.3(f) to be consistent with the revised 
specifications for salvage packaging markings in the UN Model 
Regulations. Also, to be consistent with the UN Model Regulations, and 
to allow shippers necessary time to implement the new marking 
requirements, we propose a transitional period to authorize a marking 
that is in conformance with the requirements of the regulations in 
effect on October 1, 2012, to be used until December 31, 2016. Finally, 
PHMSA realizes that in domestic transportation numerous salvage and 
salvage cylinder markings are in service that are of a more permanent 
nature. In recognition of this PHMSA is proposing that for domestic 
transportation, a salvage packaging or a salvage cylinder that is 
permanently marked prior to January 1, 2017 in conformance with the 
requirements of the regulations in effect on October 1, 2012, may 
continue in service until the end of its useful life.
    Also PHMSA is proposing to add a new paragraph (f) to Sec.  173.3 
authorizing and prescribing the use of large salvage packaging for all 
modes of transportation other than air.
Section 173.4a
    To promote the uniformity of markings, throughout the international 
transportation community, the UN Model Regulations have been revised to 
clarify and standardize the specifications for the excepted quantities 
marking. In this NPRM, PHMSA is proposing to revise the specifications 
for the excepted quantities marking prescribed in Sec.  173.4a(g)(2) to 
be consistent with the revised specifications for these markings in the 
UN Model Regulations. Also consistent with the UN Model Regulations, we 
propose to allow manufacturers and printers necessary time to retool to 
produce markings that conform to the revised specifications, and to 
allow for the depletion of supplies of existing markings, a 
transitional period is being proposed to authorize an excepted 
quantities marking that is in conformance with the requirements of the 
regulations in effect on October 1, 2012, to be used until December 31, 
2016.
Section 173.9
    To promote the uniformity of markings, UN Model Regulations have 
been revised to clarify and standardize the specifications for the 
fumigant marking. In this NPRM, PHMSA is proposing to revise the 
specifications for the fumigant marking prescribed in Sec.  173.9(e) to 
be consistent with the revised specifications for these markings in the 
UN Model Regulations. Also consistent with the UN Model Regulations, to 
allow manufacturers and printers necessary time to retool to produce 
markings that conform to the revised specifications, and to allow for 
the depletion of supplies of existing markings, we propose a 
transitional period to authorize a fumigant marking that is in 
conformance with the requirements of the regulations in effect on 
October 1, 2012, to be used until December 31, 2016.
Section 173.11
    In this NPRM, PHMSA proposes to add a new Sec.  173.11 providing 
exceptions to the regulations for certain lamps containing hazardous 
materials based on their transport conditions, the quantity of 
hazardous materials contained in each lamp or package, and the type of 
packaging. This proposed new section is consistent with newly adopted 
provisions in the UN Model Regulations.
Section 173.24
    In this NPRM, PHMSA proposes to revise Sec.  173.24 to authorize 
the use of supplementary packagings within an outer packaging (e.g., an 
intermediate packaging or a receptacle inside a required inner 
packaging) in addition to what is required by the regulations provided 
all applicable requirements are met and, if appropriate suitable 
cushioning is used to prevent movement within the packaging. This 
proposed revision is consistent with newly adopted provisions in the UN 
Model Regulations.
Section 173.25
    To promote the uniformity of markings, the UN Model Regulations 
have been revised to clarify and standardize the specifications for the 
overpack marking. In this NPRM, PHMSA is proposing to revise the 
specifications for the overpack marking prescribed in Sec.  
173.25(a)(4) to be consistent with the revised specifications for these 
markings in the UN Model Regulations. Also consistent with the UN Model 
Regulations, to allow manufacturers and printers necessary time to 
retool to produce markings that conform to the revised specifications, 
and to allow for the depletion of supplies of existing markings, we 
propose a transitional

[[Page 50762]]

period to authorize an overpack marking that is in conformance with the 
requirements of the regulations in effect on October 1, 2012, to be 
used until December 31, 2016.
Section 173.62
    Consistent with the UN Model Regulations, in this NPRM, PHMSA is 
proposing to revise Sec.  173.62 relating to specific packaging 
requirements for explosives as follows:
    In paragraph (b), in the Explosives Table, the entry for UN0222 is 
revised to expand the packaging authorizations to include Packing 
Instruction 117 in addition to the existing Packaging Instructions 
112(b) and 112(c).
    In paragraph (c), in the Table of Packing Methods, Packing 
Instruction 116 would be revised to delete provision 5, which states 
that woven plastic bags (5H2 or 5H3) must be used only for UN 0082, 
0241, 0331 and 0332. Packing Instruction 117 would be revised to add 
provision 5 which states, ``For UN0222, when other than metal or rigid 
plastics IBCs are used, they must be offered for transportation in a 
closed freight container or a closed transport vehicle.''; and 
provision 6 which states, ``For UN0222, flexible IBCs must be sift-
proof and water-resistant or must be fitted with a sift-proof and 
water-resistant liner.'' Packing Instructions 131 and 137 would be 
revised to expand the authorization for outer packagings to include 
solid plastic boxes (4H2).
Section 173.115
    Section 173.115 prescribes the definitions for Class 2 materials. 
In this NPRM a new paragraph (m) is proposed to define the term 
``Adsorbed gas''. The term means a gas which when packaged for 
transport is adsorbed onto a solid porous material resulting in an 
internal receptacle pressure of less than 101.3 kPa at 20 [deg]C and 
less than 300 kPa at 50 [deg]C.
    Currently the HMR do not prescribe requirements for the transport 
of adsorbed gases. In this NPRM, PHMSA is proposing to adopt various 
transportation requirements for adsorbed gases. Prior to adoption of 
such standards, the term ``Adsorbed gas'' must be defined. Therefore in 
this NPRM we are proposing to adopt the above definition of an adsorbed 
gas based on the definition found in the 18th Revised Edition of the UN 
Model Regulations, the IMDG Code and the ICAO TI.
Section 173.121
    Section 173.121 prescribes the requirements for the 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. Paragraph (b)(1)(ii) currently states 
that the mixture cannot contain any substances with a primary or 
subsidiary risk of Division 6.1 or Class 8. In this NPRM, PHMSA 
proposes to revise paragraph (b)(1)(ii) to clarify that a mixture or 
any separated solvent cannot contain any substances with a primary or 
subsidiary risk of Division 6.1 or Class 8. This proposed change is 
consistent with the current language in the 18th Revised Edition of the 
UN Model Regulations, the IMDG Code and the ICAO TI.
Section 173.127
    In this NPRM, PHMSA is proposing to revise Sec.  173.127(a) to 
authorize an alternative test for assigning packing groups to Division 
5.1 oxidizing solids. The proposed test is in addition to the currently 
authorized test using potassium bromate. The alternative test uses 
calcium peroxide as a reference substance which is neither carcinogenic 
nor as acutely toxic as potassium bromate. In addition, the proposed 
alternative test replaces the highly subjective visual determination of 
the burning time with a gravimetric determination of the burning rate. 
This change is consistent with the test adopted into the UN Model 
Regulations.
Section 173.151
    Section 173.151 provides exceptions for Class. In this NPRM PHMSA 
is proposing to revise paragraph (b) to replace a pre-existing 
paragraph (b)(2) relating to exceptions for charcoal briquettes 
(NA1361) that was inadvertently deleted in the final rule dated January 
7, 2013 (HM-215K; 78 FR 1101).
Section 173.161
    Section 173.161 prescribes packaging requirements for chemical kits 
and first aid kits that contain small amounts of hazardous materials. 
Paragraph (b)(2) contains the requirement that ``The packing group 
assigned to the chemical kit and first aid kit as a whole must be the 
most stringent packing group assigned to any individual substance in 
the kit.'' This requirement creates problems for shippers and air 
transport acceptance personnel because it does not specify what must be 
shown for the packing group on the shipping paper or what packaging 
standard must be applied to kits containing hazardous materials to 
which no packing group is assigned. In this NPRM, PHMSA is proposing to 
revise paragraph (b)(2) to require that for kits containing only 
hazardous materials to which no packing group is assigned, a packing 
group need not be indicated on the shipping paper although such 
packagings shall meet the Packing Group II performance level.
Section 173.164
    Section 173.164 prescribes requirements for the transportation of 
Mercury (metallic and articles containing mercury). In this NPRM, PHMSA 
is eliminating the existing exception for lamps containing mercury in 
paragraph (b)(5). This paragraph will be redundant and unnecessary 
since this exception will be covered in the proposed new Sec.  173.11 
relating to exceptions for shipment of lamps containing hazardous 
materials.
Section 173.166
    Section 173.166 prescribes requirements for the transportation of 
air bag inflators, air bag modules and seat-belt pretensioners, UN3268 
and UN0503. Due to technological developments, new safety devices for 
vehicles are becoming available. The devices include pyromechanical 
devices that meet the definition of a hazardous material but are not 
accurately described by the proper shipping names Air bag inflators, 
Air bag modules, or Seat-belt pretensioners. The proper shipping name 
for these devices has been revised in the UN Model Regulations to 
``Safety devices, electrically initiated'' for UN 3268 and ``Safety 
devices, pyrotechnic'' for UN0503. Consistent with the UN Model 
Regulations, in this NPRM, PHMSA is proposing to adopt these revised 
proper shipping names and revise Sec.  173.166 to adopt the term 
``Safety Devices'' for these items. An entry for the existing proper 
shipping name ``Air bag inflators, or Air bag modules, or Seat-belt 
pretensioners'' has been left in the Sec.  172.101 Hazardous Materials 
Table to direct the reader to the new proper shipping names ``Safety 
devices, electrically initiated'' and ``Safety devices, pyrotechnic.''
    Also, the current Sec.  173.166(b)(1)(iv) provides that under 
certain conditions a Class 9 (UN3268) air bag inflator, air bag module, 
or seat-belt pretensioner design is not required to be submitted to the 
Associate Administrator for approval or assigned an EX number. Air bag 
inflators, air bag modules, and seat-belt pretensioners have a long 
history of safety in their design and manufacture. However, new types 
of safety devices such as pyromechanical devices do not yet have an 
established history. Therefore in the interest of safety PHMSA is 
proposing not to extend this

[[Page 50763]]

exception to all Class 9 safety devices but only maintain this 
exception for air bag inflators, air bag modules, and seat-belt 
pretensioners and still require that other types of safety devices, 
such as pyromechanical devices, that are candidates for Class 9 be 
submitted to the Associate Administrator for approval or assigned an EX 
number. Finally, in this NPRM, PHMSA proposes to add a new paragraph 
(d)(5) to Sec.  173.166 to permit the continued transportation of an 
air bag inflator, air bag module, or seat-belt pretensioner that was 
classed and approved for transportation prior to January 1, 2015 under 
the terms of the existing approval, using the proper shipping name 
``Safety Devices'' or ``Safety Devices, Pyrotechnic'' as appropriate.
Section 173.167
    Section 173.167 prescribes the requirements for consumer 
commodities intended for air transportation. In this NPRM, PHMSA is 
proposing to revise the drop test requirements in (a)(4) by including 
the criteria for passing the test. A completed consumer commodity 
package will be considered to have passed the drop test if the outer 
packaging does not exhibit any damage liable to affect safety during 
transport and there is no leakage from the inner packaging(s).
Section 173.176
    Section 173.176 addresses capacitors by prescribing the testing, 
marking, safety, and packaging requirements for electric double layer 
capacitors with energy storage capacity greater than 0.3 watt hours 
(Wh). In this NPRM, PHMSA is proposing to revise section 173.176 to 
include provisions for asymmetric capacitors in accordance with the new 
HMT entry ``UN3508, Capacitor, asymmetric (with an energy storage 
capacity greater than 0.3Wh).'' In addition, paragraph (a)(5) presently 
requires that capacitors must be marked with the energy storage 
capacity in Wh. As many pre-existing capacitors do not have Wh marking 
they are not permitted to be transported even when all other 
requirements of this section are met. In this NPRM, PHMSA is proposing 
to amend paragraph (a)(5) to require that the Wh marking is required 
for non-asymmetric capacitors manufactured after December 31, 2013 and 
for asymmetric capacitors manufactured after December 31, 2015.
Section 173.181
    Section 173.181 prescribes the non-bulk packaging requirements 
applicable to pyrophoric liquids. On January 7, 2013, PHMSA published 
final rule PHMSA-2012-0027 (HM-215L) [78 FR 987] 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. In that final 
rule PHMSA revised paragraphs (b) and (c) to add authorizations for 
additional authorized packagings for these materials. Paragraphs (c) 1-
3 were inadvertently deleted due to an incorrect amendatory instruction 
and in this NPRM PHMSA is proposing to place paragraphs (c) 1-3 back 
into Sec.  173.181 as they were prior to the publication of HM-215L. It 
was never PHMSA's intention to remove these important safety provisions 
for the transport of pyrophoric liquids, and we ask individuals who 
package and offer these materials to continue to abide by these 
requirements pending their reinsertion in the HMR.
Section 173.185
    In this NPRM, PHMSA is proposing to add paragraph (b)(6) and revise 
paragraph(f)(3) to authorize and prescribe the use of a large packaging 
for a single large lithium battery or a battery contained in equipment. 
This authorization does not include transportation by aircraft. The 
proposed addition of this packaging type into this section is 
consistent with provisions for lithium batteries in the UN Model 
Regulations.
    The ICAO DGP took a decision during the most recent biennium to 
remove the alternative written documentation option in Section IB of 
ICAO Packing Instructions 965 and 968 and instead require a standard 
transport document (shipping paper). Section IB is applicable to 
packages that exceed the number or quantity (mass) limits for smaller 
lithium batteries in Section II of Packing Instructions 965 and 968 
excepting such packages from specification packaging requirements when 
containing no more than 2.5 kg of lithium metal cells or batteries or 
10 kg of lithium ion cells or batteries per package. As this revision 
will appear in the 2015-2016 Edition of the ICAO TI, in this NPRM PHMSA 
is proposing to amend paragraph (c)(4)(v) to require a shipping paper 
for these packages containing no more than 2.5 kg of lithium metal 
cells or batteries or 10 kg of lithium ion cells or batteries per 
package. PHMSA is seeking input as to the costs and benefits of 
harmonizing the provisions of the HMR with the provisions of the ICAO 
Technical Instructions by requiring shipping papers as opposed to 
alternative documentation. PHMSA also solicits comments on the costs 
and benefits of maintaining a domestic difference within the HMR to 
continue to allow the use of the alternative documentation in lieu of a 
shipping paper as required by the ICAO Technical Instructions.
    The ICAO Working Group on Lithium Batteries, at their April 2014 
meeting, forbid the shipment of lithium metal cells and batteries as 
cargo on passenger aircraft with the exception of lithium metal cells 
and batteries packed with or contained in equipment not exceeding 5 kg 
net weight. This prohibition of lithium metal batteries as cargo on 
passenger aircraft is consistent with current HMR requirements. As a 
consequence to this prohibition, Section II of Packing Instruction 968 
in the ICAO TI was amended to require shipments of small lithium metal 
cells and batteries to display the ``CARGO AIRCRAFT ONLY'' label where 
previously only a lithium battery handling marking was required. 
Presently under the HMR, a package containing such lithium metal cells 
or batteries as provided in Sec.  173.185(c)(1)(iii), is required to be 
marked ``PRIMARY LITHIUM BATTERIES--FORBIDDEN FOR TRANSPORT ABOARD 
PASSENGER AIRCRAFT'' or ``LITHIUM METAL BATTERIES--FORBIDDEN FOR 
TRANSPORT ABOARD PASSENGER AIRCRAFT.'' Following the change to the ICAO 
TI, the present text marking will now be redundant for international 
shipments. In this NPRM, PHMSA is proposing to provide an alternative 
to the existing marking requirement in Sec.  173.185(c)(1)(iii) with 
the option to display a ``CARGO AIRCRAFT ONLY'' label. This allowance 
to either utilize the current marking or the ``CARGO AIRCRAFT ONLY'' 
label will provide shippers with the flexibility to utilize supplies of 
preprinted markings or packagings, while also allowing shippers to 
transition to the use of the ``CARGO AIRCRAFT ONLY'' if desired.
Section 173.199
    To promote the uniformity of markings, the UN Model Regulations 
have been revised to clarify and standardize the specifications for the 
square-on-point marking for Category B infectious substances. In this 
NPRM, PHMSA is proposing to revise the specifications for the Category 
B infectious substance marking prescribed in Sec.  173.199(a)(5) to be 
consistent with the revised specifications for these markings in the UN 
Model Regulations. Also consistent with the UN Model Regulations, to 
allow manufacturers and

[[Page 50764]]

printers necessary time to retool to produce markings that conform to 
the revised specifications, and to allow for the depletion of supplies 
of existing markings, we propose a transitional period to authorize a 
Category B infectious substance marking that is in conformance with the 
requirements of the regulations in effect on October 1, 2012, to be 
used until December 31, 2016.
Section 173.225
    Section 173.225 prescribes packaging requirements and other 
provisions for organic peroxides. In this NPRM, PHMSA is proposing to 
revise the Organic Peroxide Portable Tank Table in paragraph (g). PHMSA 
proposes to revise the entry in the second column of the table 
pertaining to the hazardous material ``Peroxyacetic acid, distilled, 
stabilized, not more than 41%'' to include a Note 1, that a 
````Corrosive'' subsidiary risk placard is required.'' The proposed 
adoption of this requirement is consistent with the requirements in the 
UN Model Regulations.
Section 173.231
    Currently, the Sec.  172.101 HMT Column (8B) and (8C) packaging 
authorization for Ammonium nitrate emulsion, suspension, or gel, 
UN3375, directs the reader to Sec.  173.214 which requires that 
packagings and method of shipment must be approved by the Associate 
Administrator prior to the first shipment. In this NPRM, PHMSA is 
proposing to add a new Sec.  173.231 titled ``Ammonium nitrate 
emulsion, suspension or gel'' and assigned this section to UN3375 to 
authorize and prescribe the use of packagings for this material. The 
requirements of the proposed new section are consistent with the 
requirements in the UN Model Regulations.
 Section 173.301b
    In this NPRM, PHMSA is proposing to revise paragraph (c) relating 
to pressure receptacle valve requirements to include that a valve 
manufactured on or before December 31, 2008, conforming to the 
requirements in ISO 10297:1999 is authorized. This proposed revision is 
consistent with the requirements in the UN Model Regulations.
Section 173.302
    In this NPRM, PHMSA is proposing to adopt the new UN Model 
Regulation requirements for the transportation of adsorbed gases in 
cylinders. This section specifies requirements for the filling of 
cylinders with non-liquefied (permanent) compressed gases. PHMSA is 
proposing to amend the title of this section and to amend paragraph (a) 
to include and specify requirements for the transportation of adsorbed 
gases.
Section 172.302c
    In this NPRM, PHMSA is proposing to add a new Sec.  173.302c to 
adopt the new authorization in the UN Model Regulations for the 
transportation of adsorbed gases in UN pressure receptacles. The 
proposed adoption of these requirements into this new section is 
consistent with the requirements in the UN Model Regulations.
Section 173.307
    Section 173.307 provides exceptions from the regulations for 
compressed gases. In this NPRM, PHMSA is proposing to revise paragraph 
(a)(5) relating to manufactured articles or apparatuses to clarify that 
the exception for manufactured articles does not include lamps. The 
exceptions for lamps are contained in the proposed new Sec.  173.11 
relating to exceptions for shipment of lamps containing hazardous 
materials. Also, we are proposing to revise paragraph (a)(6) relating 
to light bulbs to clarify that the exceptions does not apply to lamps 
as described in the proposed new Sec.  173.11 relating to exceptions 
for shipment of lamps containing hazardous materials.
Section 173.309
    Section 173.309 prescribes requirements for fire extinguishers. In 
this NPRM, we are proposing to add a new introductory paragraph 
describing fire extinguisher types authorized for transport in 
accordance with this section and covered by the HMT entry ``UN1044, 
Fire extinguishers.''
Section 173.403
    Consistent with the UN Model regulations, in this NPRM, PHMSA is 
proposing to revise two definitions in Sec.  173.403 relating to the 
transportation of Class 7 (Radioactive Materials). ``Exclusive Use'' is 
being revised to clarify that it also applies to the shipment of the 
load and that exclusive use only applies when compliance is required by 
the regulations. ``Freight Container'' is being revised to eliminate 
the requirement that a ``small freight container'' has one outer 
dimension less than 1.4 m (4.9 feet).
Section 173.420
    Section 173.420 prescribes the transport conditions for Uranium 
hexafluoride. In this NPRM PHMSA is proposing to amend paragraph (d) 
which provides the requirements for shipments of uranium hexafluoride 
in quantities less than 0.1 kg to incorporate changes made by the IAEA 
in SSR-6 that were subsequently incorporated in the UN Model 
Regulations. In this NPRM PHMSA is proposing to amend this paragraph to 
note that fissile-excepted shipments less than 0.1 kg may be offered 
under UN3507. PHMSA is proposing to amend the requirements for these 
shipments to align with IAEA SSR-6 requirements, while maintaining 
general packaging requirements from Sec. Sec.  173.24 and 173.24a.

Part 175

Section 175.9
    Section 175.9 prescribes the applicability of the HMR to special 
aircraft and rotocraft operations. This section also prescribes the 
conditions under which certain operations may be performed in 
accordance with 14 CFR and 49 CFR (e.g., avalanche and weather 
control). Consistent with the ICAO TI, in this NPRM, PHMSA is proposing 
to revise paragraphs (b)(6) and (b)(6)(v) by including ``ice jam 
control'' and ``landslide clearance'' for operations where explosives 
are used in a similar manner to avalanche control.
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 TI, in this NPRM, PHMSA 
is proposing several revisions to this section.
    PHMSA is proposing to revise paragraph (a)(11), applicable to 
passenger provisions for self-inflating life jackets, to include 
different types of self-inflating personal safety devices in order to 
account for those carried by, but not limited to, motorcycle and 
horseback riders. In addition, PHMSA is clarifying that a passenger is 
limited to one self-inflating safety device, in addition to two spare 
cartridges, and is requiring that both the safety device and spares be 
packed in such a manner that they cannot be accidently activated.
    PHMSA is proposing to add a new subparagraph (a)(18)(iv) to clarify 
that articles containing lithium metal or lithium ion cells or 
batteries, with a primary function to provide power to another device, 
must carried as spare batteries in accordance with the provisions of 
this paragraph.
    PHMSA is proposing to revise paragraph (a)(24), applicable to small 
cartridges for other devices, by amending the phrase ``small 
cylinders'' to the more appropriate phrase ``small cartridges,'' and 
restricting the carriage of small gas cartridges to only those without 
a subsidiary risk. The existing

[[Page 50765]]

operator approval requirement was moved to make it more clearly align 
with the ICAO TI.
Section 175.25
    Section 175.25 prescribes the notification that operators must 
provide to passengers regarding restrictions on the types of hazardous 
material they may or may not carry aboard an aircraft on their person 
or in checked or carry-on baggage. Consistent with revisions to the 
ICAO TI, in this NPRM, PHMSA is proposing to revise paragraph (b) as 
follows: (1) For all ticket purchases, clarify that the hazardous 
materials notification must be presented at the point of ticket 
purchase, or if this is not practical, made available to passengers in 
another manner prior to the check-in process and; (2) for such internet 
purchases, require that the final ticket purchase cannot be completed 
until the passenger or a person acting on the passenger's behalf has 
been presented with this information, in addition to the existing 
requirement to indicate that they understand the restrictions on 
hazardous materials in baggage. In this NPRM, PHMSA is proposing to 
revise paragraph (c) as follows: (1) Replace the text ``provided'' with 
``presented'' to make it clear that passengers must see information on 
the types of hazardous material forbidden to be transported before 
proceeding with check-in. It was reported that some operators published 
the required information in areas on a Web site that were not always 
visible to the passenger, believing that this met the requirement of 
being ``provided'' and; (2) require that the check-in process cannot be 
completed until the passenger or a person acting on the passenger's 
behalf has been presented with the hazardous materials information, in 
addition to the existing requirement to indicate that they understand 
the restrictions on hazardous materials in baggage.
    In paragraphs (b) and (c) PHMSA is proposing to remove the present 
effective dates of January 1, 2015 and the word ``phone'' used as an 
example of a ticket purchase or check-in completed remotely. 
Furthermore, PHMSA is proposing to remove the words ``regardless if the 
process is completed remotely (e.g., via the Internet and Phone) or 
when completed at the airport, with or without assistance from another 
person (e.g., automated check in facility)'' in order to bring 
paragraph (b) into full alignment with 7;5.1.1 of the ICAO TI. By 
removing the examples in conjunction with other revisions to paragraph 
(b) it is now clear that passenger notification is required for all 
ticket purchases; however, for assisted ticket purchase transactions 
via the telephone the hazardous material information may be provided to 
the passenger using any suitable method prior to the check-in process 
and passenger acknowledgement is not required. These revisions 
represent full harmonization with the ICAO TI and additional 
flexibility in meeting the passenger notification requirements and, 
therefore, the previous effective date of January 1, 2015 will be 
waived as of publication of the rule.
    In addition, the revision proposed in this NPRM providing 
clarification for ticket purchases made via the telephone, permitting 
the hazardous materials notification to be made available in another 
manner to passengers prior to the check-in process, is consistent with 
a petition for rulemaking (P-1623) filed by COSTHA.
Section 175.30
    Section 175.30 prescribes inspection procedures for operators. 
Paragraph (e)(1) prohibits an overpack from containing a package 
bearing the ``CARGO AIRCRAFT ONLY'' label unless certain conditions are 
met and that the overpack affords clear visibility of and easy access 
to the package contained within. In this NPRM, PHMSA is proposing to 
remove paragraph (e)(1) consistent with revisions made to the ICAO TI 
in which current provisions require accessibility to the overpack when 
loaded aboard an aircraft, not the individual packages contained 
within, making reference to packages redundant. As the loading 
requirements in Sec.  175.75(d)(1) require a package bearing the 
``CARGO AIRCRAFT ONLY'' label to be accessible once loaded on the 
aircraft, but do not require they are visible, the requirements in 
(e)(1) place an unnecessary burden on offerers without any additional 
safety function in the loading process.
    Paragraph (a)(5) states that no person may accept for 
transportation aboard an aircraft shipments of lithium batteries 
described with an alternative written document authorized in Sec.  
173.185(c)(4)(v). The proposed removal of the alternative written 
document from Sec.  173.185(c)(4)(v) necessitates the removal of this 
paragraph.
Section 175.33
    Section 175.33 establishes requirements for shipping papers and for 
the notification of the pilot-in-command when hazardous materials are 
transported by aircraft.
    With the exception of package type, paragraph (a)(1)(i) currently 
requires any additional shipping paper description requirements 
provided in Sec. Sec.  172.202, and 172.203 to be included on the 
notification of the pilot-in-command. Section 172.203(k) requires the 
use of technical names for ``n.o.s.'' and generic descriptions for 
proper shipping names identified by the letter ``G'' in column (1) of 
the Sec.  172.101 Table. In this NPRM, PHMSA is proposing to revise 
paragraph (a)(1)(i) to state that technical names are not required to 
be provided on the notification of pilot-in-command. This clarification 
will align the HMR with changes adopted in the ICAO TI and supports the 
overall goal of harmonization. Harmonization of the notification of 
pilot-in-command requirements ensures consistency across all air 
operators thus reducing impediments in commerce and reducing costs 
associated with training to two different sets of standards. In 
addition, the technical name is not referenced in the Emergency 
Response Guidance for Aircraft Incidents Involving Dangerous Goods (Doc 
9481) or the North American Emergency Response Guidebook (ERG). The 
ICAO panel determined that the technical names provided little benefit 
to safety, particularly during the initial stage of emergency response 
while the number of materials requiring a technical name is on the 
rise, thereby increasing the burden on operators to provide this 
information. In addition, the technical name is not referenced in the 
Emergency Response Guidance for Aircraft Incidents Involving Dangerous 
Goods (Doc 9481) or the North American Emergency Response Guidebook 
(ERG).
    Paragraphs (a)(12) and (c)(5) both mention the alternative written 
document authorized in Sec.  173.185(c)(4)(v). The proposed removal of 
the alternative written document from Sec.  173.185(c)(4)(v) 
necessitates the removal of these paragraphs. Any information required 
to be a part of the notification of the pilot-in-command previously 
under paragraph (a)(12) will be detailed on a shipping paper and be 
included on the notification of the pilot-in-command.
Section 175.630
    Section 175.630 prescribes special requirements for Division 6.1 
(Toxic) and 6.2 (Infectious) materials in the HMT. Consistent with 
revisions to the ICAO TI, in this NPRM, PHMSA is proposing to remove 
paragraph (a) which prescribes segregation requirements for loading 
certain Division 6.1 or Division 6.2 materials in the same compartment 
of an aircraft

[[Page 50766]]

with material marked as or known to be a foodstuff, feed, or any other 
edible material intended for consumption by humans or animals. At the 
time these segregation requirements were initially included in the ICAO 
TI and the HMR, the packing instructions were much less detailed than 
they are at present. The UN Model Regulations do not impose segregation 
requirements for Division 6.2 infectious substances. The segregation 
requirements for infectious substances under the ICAO TI and HMR only 
apply to UN2814 and UN2900 which already require robust triple 
packagings. For Division 6.1, the UN Recommendations allow the 
segregation requirements to be relaxed for substances in Packing Groups 
II and III, provided the competent authority is satisfied that the 
packing and segregation are adequate to prevent contamination. In 
addition, the inspection procedures prescribed in Sec.  175.30 require 
a physical check to ensure that the packagings are free from damage. 
The revisions proposed in this NPRM are consistent with a petition for 
rulemaking (P-1631) filed by UPS, Inc., who voiced strong support for 
such action.
Section 175.705
    Section 175.705 prescribes requirements for aircraft that have been 
contaminated with radioactive material and the procedures that must be 
followed prior to returning the aircraft to service. Consistent with 
revisions to the ICAO TI, in this NPRM, PHMSA is proposing to revise 
paragraph (c) by stating that the dose rate at every accessible surface 
``must not exceed'' 0.005 mSv per hour, where it presently states ``is 
less than''.

Part 176

Section 176.80
    Section 176.80 details segregation requirements in addition to any 
segregation requirements set forth elsewhere in subchapter C. In this 
NPRM PHMSA is proposing a prohibition on stowing goods of Division 1.4, 
compatibility group S in the same compartment or hold, or cargo 
transport unit with hazardous materials of Class 1 of compatibility 
groups A and L. Limited quantity shipments are currently excepted from 
segregation requirements for vessel transport by both the IMDG Code and 
the HMR. The IMO noted that when creating this exception a long 
standing prohibition on stowing limited quantity goods of division 1.4, 
compatibility group S in the same compartment or hold, or cargo 
transport unit with hazardous materials of Class 1 of compatibility 
groups A and L was not carried over into amendment 36-12 of the IMDG 
Code. Amendment 37-14 of the IMDG Code reinstates these segregation 
provisions, and PHMSA is proposing an equivalent change.
Section 176.83
    Section 176.83 details segregation requirements for hazardous 
materials vessel transport. Paragraph (b) includes a table for users to 
determine segregation requirements between various Classes (Divisions) 
of hazardous materials. In this NPRM, PHMSA proposes to amend the 
segregation requirements for vessel transportation between hazardous 
materials of Class 4.3 (dangerous when wet) and Class 2.1 (flammable 
gas), and Class 3 (flammable liquid). Proposed changes in the 
segregation table in paragraph (b) are to change the segregation 
requirements between goods of Class 4.3 and Class 2.1 from an ``x'' 
(segregation, if any, is shown in the Sec.  172.101 table) to a ``2'' 
(separated from), and between goods of Class 4.3 and Class 3 from a 
``1'' (away from) to a ``2'' (separated from). The meaning of these 
terms differs depending on the method of transport onboard a vessel 
(shipping break-bulk cargo versus segregation of cargo transport units 
on board container vessels). PHMSA assumes the majority of commodities 
transported by vessel that will be affected by the proposed changes, 
are offered in closed cargo transport units (CTU). A description of the 
proposed changes, and how they will be impact these CTUs, is outlined 
in the following table.

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

    The proposed changes are based on amendments adopted by the IMO and 
are aimed at enhancing efforts to prevent the spread of fire in an 
emergency situation. Fire extinguishing methods available to vessel 
crews are often quite limited. Due to these limited fire extinguishing 
options, the only recommended option to control the consequences of a 
fire originating from these goods is to let the fire burn and to 
prevent the spread of fire to other cargo or equipment which is crucial 
for the safe operation of the ship. The proposed changes are intended 
to address situations where a fire originates in a shipment of 
flammable liquids or gases and is likely to spread to goods which 
cannot be extinguished, or when a fire originates in goods which cannot 
be extinguished and threatens to spread to highly flammable goods. The 
new proposed segregation distances will enhance efforts to control the 
emergency situation.
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

[[Page 50767]]

defined in the ``table of provisions'' in paragraph (b), and the 
stowage provisions applicable to vessel shipments of Class 1 
explosives, which are defined in the table to paragraph (c)(2).
    In this NPRM, PHMSA is proposing to amend the title of the section 
to note that the codes in column 10B address not only codes for stowage 
requirements, but also handling requirements that need to be observed 
during loading of the hazardous materials. PHMSA is also proposing to 
create footnote 3 and assign it to stowage provision 12 and 13. 
Footnote 3 is added to note that these provisions apply not only to 
stowage of the cargo transport unit, but also to the loading of 
hazardous materials into the cargo transport unit.
    PHMSA is additionally proposing to create new stowage provisions 
147 and 148 consistent with changes adopted in Amendment 37-14 of the 
IMDG Code. Stowage provision 147 is proposed to read ``Stow ``separated 
from'' flammable gases and flammable liquids.'' Stowage provision 148 
is proposed to read ``In addition: From flammable gases and flammable 
liquids when stowed on deck of a containership a minimum distance of 
two container spaces athwartship shall be maintained, when stowed on 
ro-ro ships a distance of 6 m athwartship shall be maintained.''
Section 176.905
    Section 176.905 prescribes specific requirements for motor vehicles 
or mechanical equipment powered by internal combustion engines that are 
offered for transportation and transported by vessel. In this NPRM 
PHMSA is proposing to align our exceptions for vessel transportation 
for motor vehicles and mechanical equipment powered by internal 
combustion engines with those recently adopted by the IMO. PHMSA 
believes aligning these exceptions will enhance the safe vessel 
transport of motor vehicles and mechanical equipment powered by 
internal combustion engines.
    PHMSA is proposing to amend paragraphs (i)(1), (i)(2), (i)(4), and 
(i)(5) to require as a condition of exception from the subchapter that 
batteries installed in motor vehicles or mechanical equipment powered 
by internal combustion engines be protected from short circuit. PHMSA 
is also proposing to revise paragraph (i)(2), which provides conditions 
that need to be met for vehicles or mechanical equipment with an 
internal combustion engine that uses liquid fuel with a flashpoint of 
38 [deg]C (100[emsp14][deg]F) or higher. Currently up to 418 L (110 
gallons) may remain in the equipment or vehicle, and if other noted 
conditions are met the vehicle is excepted from all other requirements 
of subchapter C. PHMSA is proposing to amend this fuel threshold to 450 
L (119 gallons).
    PHMSA is proposing to add paragraph (i)(6) to add exceptions for 
fuel cell powered vehicles or mechanical equipment with an internal 
combustion engine powered by fuel cells. When the engine is protected 
from inadvertent operation by closing fuel supply lines or by other 
means, and the fuel supply reservoir has been drained and sealed, the 
vehicle or mechanical equipment is excepted from the requirements of 
subchapter C.

Part 178

Section 178.71
    Consistent with the UN Model Regulations, in this NPRM, PHMSA is 
proposing to revise paragraph (a) to clarify that UN pressure 
receptacles and service equipment constructed according to the 
standards applicable at the date of manufacture may continue in use 
subject to the continuing qualification and maintenance provisions of 
part 180 of the subchapter.
    Consistent with the UN Model Regulations PHMSA is proposing to 
revise paragraphs (d)(2), (g), and (k) to reflect the adoption of the 
latest ISO standards for the design, construction, and testing of gas 
cylinders and their associated service equipment. These paragraphs also 
contain proposed end dates when the manufacture of cylinders and 
service equipment are no longer authorized to be manufactured in 
accordance with the outdated ISO standard.
    Consistent with the UN Model Regulations PHMSA is proposing a new 
paragraph (n) and the redesignation of the existing paragraphs (n) 
through (s). The proposed new paragraph (n) adopts design and 
construction requirements of UN cylinders for the transportation of 
adsorbed gases, consistent with those adopted into the UN Model 
Regulations.
    Consistent with the UN Model Regulations, PHMSA is proposing to 
revise the proposed redesignated paragraph (o) to adopt the current ISO 
standards relating to material compatibility.
    Finally, PHMSA is proposing to add new paragraphs (u) and (v) to 
adopt the marking requirements for bundles of cylinders that have been 
adopted in the UN Model regulations.
Section 178.75
    Consistent with the UN Model Regulations PHMSA is proposing to 
revise paragraph (d)(3) to reflect the adoption of the latest ISO 
standards for the design, construction, and testing of gas cylinders 
that are part of MEGCs. This paragraph also contains proposed end dates 
when the manufacture of cylinders that are part of MEGCs are no longer 
authorized to be manufactured in accordance with the outdated ISO 
standard.
Section 178.703
    To promote the uniformity of markings, throughout the international 
transportation community, revisions have been adopted in the UN Model 
Regulations to clarify and standardize the specifications for markings, 
including the marking of IBCs. In this NPRM, PHMSA is proposing to 
revise the specifications for the markings prescribed in Sec.  
178.703(b)(7)(iii) to be consistent with the revised specifications for 
these markings in the UN Model Regulations. Also consistent with the UN 
Model Regulations, a transitional period is being proposed to authorize 
markings in conformance with the requirements of this paragraph in 
effect on October 1, 2012, to continue to be applied to all IBCs 
manufactured, repaired or remanufactured between January 1, 2011 and 
December 31, 2016.
Section 178.910
    In this NPRM, PHMSA is proposing to revise paragraph (a) relating 
to the marking of large packagings to include markings for the proposed 
large salvage packagings. Consistent with the UN Model Regulations, 
following the large packaging design type identification code on a 
large packaging. a large salvage packaging conforming to the 
requirements of subpart P of part 178 is proposed to be marked with the 
letter ``T''.
    In addition, to promote the uniformity of markings, throughout the 
international transportation community, revisions have been adopted in 
the UN Model Regulations to clarify and standardize the specifications 
for markings, including the marking of large packagings and large 
salvage packaging. In this NPRM, PHMSA is proposing to revise the 
specifications for the markings prescribed in Sec.  178.910(b) to be 
consistent with the revised specifications for these markings in the UN 
Model Regulations. Also consistent with the UN Model Regulations, a 
transitional period is being proposed to authorize markings in 
conformance with the requirements of this paragraph in effect on 
October 1, 2012, to continue to be applied to all large packagings 
manufactured, repaired or

[[Page 50768]]

remanufactured between January 1, 2015 and December 31, 2016.

Part 180

Section 180.207
    Requirements for requalification of UN pressure receptacles are 
prescribed in Sec.  180.207. Table 1 in paragraph (c) of Sec.  180.207 
provides requalification intervals for UN pressure vessels. In this 
NPRM, PHMSA is proposing to add an additional entry to the end of Table 
1 to prescribe a requalification interval of 5 years for pressure 
receptacles used for adsorbed gases. This requalification period is 
consistent with the requalification period adopted in the UN Model 
Regulations for the use of these cylinders. Section 173.302c relating 
to authorization for the use of cylinders for adsorbed gases directs 
the reader to this section for the requalification period for these 
cylinders.
    The proposed paragraph (d)(5) provides that each UN cylinder used 
for adsorbed gases must be inspected and tested in accordance with 
Sec.  173.302c and ISO 11513:2011. Both Sec.  173.302c and ISO 
11513:2011 are being proposed for adoption in this NPRM.

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 with the biennial updates of 
the UN Model Regulations, the IMDG Code and the ICAO TI.
    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 TI. 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 Energy
U.S. Department of Interior

    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 18th Revised Edition of the UN Model Regulations, 
Amendment 37-14 to the IMDG Code, and the 2015-2016 Edition of the ICAO 
TI, which become effective January 1, 2015. The large volume of 
hazardous materials transported in international commerce 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 an earlier regulatory evaluation,\1\ we estimated a proxy for 
benefits of harmonization of the HMR with international standards of 
$62 million. More specifically, this $62 million was estimated by 
multiplying a hazard communication cost per dollar of hazardous 
materials output--$0.001--by the value of hazardous materials involved 
in international trade, as estimated by the proportion of trade (the 
total of gross imports and gross exports) in the fuels and lubricants, 
chemicals, and medicinal/dental/pharmaceutical products industries 
($498 billion in 2010) \2\ that are hazardous products (i.e., 12.4 
percent).\3\ \4\
---------------------------------------------------------------------------

    \1\ HM-215L: Hazardous Materials: Harmonization with 
International Standards (RRR), Final Rule, Section V.B., 78 FR 1023 
et seq., January 7, 2013.
    \2\ As reported in the quarterly trade data of the U.S. Bureau 
of Economic Analysis, available at: http://www.bea.gov/international/detailed_trade_data.htm.
    \3\ U.S. Census Bureau's 2007 Commodity Flow Survey, Table 10.
    \4\ See Section V.B. for more detailed calculations of these 
figures.
---------------------------------------------------------------------------

    For estimating benefits of this Amendment 1, we follow a nearly 
identical approach (acknowledging there is an inherent imprecision of 
benefits here), updating data and assumptions where possible. 2012 
Commodity Flow Survey data on hazardous materials are not yet available 
as of the date of this regulatory evaluation.
    However, the 12.4 percent proportion (of total shipment values 
classed as hazardous materials) estimated in the earlier regulatory 
evaluation may have had a high-side bias due to the variety of 
different classes of products classified as hazardous. In actuality, 
the percentage of shipments properly classified as hazardous is likely 
lower, particularly for medicinal/dental/pharmaceuticals. Here, we 
assume a slightly lower proportion to arrive at an estimate of benefits 
of 10 percent.
    We update our estimate of value of hazardous materials involved in 
international trade by using U.S. Trade in Goods seasonally adjusted, 
Census-based total gross imports and gross exports in the fuels and 
lubricants, chemicals, and medicinal/dental/pharmaceutical products 
industries for the fourth quarter of 2013, the most recent quarter 
available--

[[Page 50769]]

     Gross imports: $134 billion (rounded)
    [cir] Fuels and lubricants: $94.744 billion
    [cir] Chemicals: $18.637 billion
    [cir] Medicinal/dental/pharmaceutical products: $20.613 billion
     Gross exports: $85.8 billion (rounded)
    [cir] Fuels and lubricants: $44.301 billion
    [cir] Chemicals: $30.089 billion
    [cir] Medicinal/dental/pharmaceutical products: $11.416 billion
     Gross imports plus gross exports: $219.8 billion \5\

    \5\ Bureau of Economic Analysis, U.S. Department of Commerce, 
U.S. Trade in Goods (IDS-0008), available at: http://www.bea.gov/international/detailed_trade_data.htm.
---------------------------------------------------------------------------

    Multiplying the quarterly estimate of $219.8 billion by 4 gives an 
annual estimate of gross imports plus gross exports in the three 
industries of $879.2 billion. Multiplying this figure by 10 percent 
(the estimated proportion of annual trade in these three industries 
that are hazardous products) by the average hazard communication cost 
per dollar of hazardous materials produced in the United States 
($0.001) results in an estimate of benefits from Amendment 1 of $87.9 
million (rounded) annually.
    If U.S. regulations are not harmonized with international 
standards, we estimate that it will cost U.S. companies an additional 
$87.9 million per year to comply with both the HMR and the 
international standards. Harmonizing the HMR with the international 
standards, however, will avert these $87.9 million in additional costs, 
and these averted costs are therefore considered the primary benefit 
attributable to this rulemaking.
    Costs of Harmonization. The primary cost of updating references in 
the U.S. HMR (to incorporate the most recent international hazardous 
material standards) is the purchase of updated copies of the 
international standards being incorporated by reference in the HMR. 
These costs will be borne by offerors and transporters of hazmat if 
this rulemaking were finalized.
    It is unknown how many individuals and firms involved in shipping 
hazmat will purchase copies of these international standards as a 
result of finalizing this rulemaking. We take a conservative approach 
to estimating such a figure by using as a proxy the number of shippers, 
carriers, or other offerors or transporters of hazmat in commerce with 
a PHMSA registration expiring in 2014. Currently, PHMSA's registration 
database indicates 36,731 registrants as of May 20, 2014.\6\ Of these, 
29,877 (approximately 81 percent) are small businesses as defined by 
the U.S. Small Business Administration. Further, 31,598 registrants 
(approximately 86 percent) indicated that they offer or transport 
hazmat solely by highway method.
---------------------------------------------------------------------------

    \6\ See PHMSA Hazardous Materials Registration Program 
Registration Data Files, link available at http://www.phmsa.dot.gov/hazmat/registration, accessed on May 20, 2014.
---------------------------------------------------------------------------

    If we assume (for conservative estimation purposes) that all 
registrants will purchase copies of all publications, this indicates an 
estimated cost of this amendment of $56.68 million (rounded, $1,543 
cost of all publications * 36,731 registrants). (In reality, all of the 
ISO standards incorporated will not be purchased by the majority of 
shippers and carriers, and will likely only impact a small subset of 
the regulated community. Further, it is likely that many companies will 
purchase multiple copies of the IMDG Code and ICAO TI, rather than only 
one copy. We do not believe we have sufficient data to estimate the 
precise number of registrants. However, we use one copy per registrant 
as a reasonably conservative estimate on costs of the proposed 
rulemaking.)
    However, further assuming that those who indicated that they offer 
or transport in commerce hazmat only via highway, two publications 
included in the $1,543 cost will not apply to such registrants (ICAO TI 
[for air] and IMDG Code [by vessel]). Therefore, costs for the 31,598 
highway-only registrants would total $32.99 million ($1,543--$155 [ICAO 
TI]--$344 [IMDG Code] * 31,598 highway-only registrants). 
Conservatively (i.e., overestimating costs and underestimating 
benefits) assuming all other registrants (while acknowledging that, in 
fact, some will purchase all standards copies and some will purchase 
none) will purchase updated copies of all standards publications listed 
here indicates a total cost of this Amendment 1 of $40.91 million, 
incurred once ($32.99 million + $1,543 * [36,731 total registrants--
31,598 highway-only registrants], rounded).
    Net Benefit. Based on the discussions of benefits and costs 
provided above, the estimated net benefit associated with the 
international harmonization final rule (2137-AF05) is $47 million in 
the first year after publication and $87.9 million in the second year 
after publication. Please see the complete regulatory analysis, a copy 
of which has been placed in the docket for this rulemaking, for a more 
detailed analysis of the costs and benefits of this proposed rule.

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:
     The designation, description, and classification of 
hazardous material;
     The packing, repacking, handling, labeling, marking, and 
placarding of hazardous material;
     The preparation, execution, and use of shipping documents 
related to hazardous material and requirements related to the number, 
contents, and placement of those documents;
     The written notification, recording, and reporting of the 
unintentional release in transportation of hazardous material; and
     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 the covered subject items 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, 2015. 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

[[Page 50770]]

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 collection under Office of 
Management and Budget (OMB) Control Number 2137-0034, ``Hazardous 
Materials Shipping Papers and Emergency Response Information.'' We 
anticipate that this proposed rule will result in an increase in the 
annual information collection burden of this information collection due 
to an increase in the number of shipping papers prepared for packages 
containing batteries that exceeds the number or quantity (mass) limits 
in the table shown in Sec.  173.185(c)(4), but containing no more than 
2.5 kg of lithium metal cells or batteries or 10 kg of lithium ion 
cells or batteries per package. Shipments utilizing this allowance 
currently provide alternative documentation containing the name and 
address of the offeror and consignee, the UN number, an indication of 
compliance with this paragraph (c)(4) (or the applicable ICAO Packing 
Instruction), and the number of packages and the gross mass of each 
package.
    This rulemaking identifies a revised information collection that 
PHMSA will submit to OMB for approval based on the requirements in this 
NPRM. PHMSA has developed burden estimates to reflect changes in this 
NPRM, and estimates the information collection and recordkeeping burden 
in this rule are as follows:
    OMB Control Number: 2137-0034.
    Annual Increase in Number of Respondents: 150.
    Annual Increase in Annual Number of Responses: 13,167.
    Annual Increase in Annual Burden Hours: 219.
    Annual Increase in Annual Burden Costs: $4,380.
    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 of Federal Regulations requires that PHMSA provide interested 
members of the public and affected agencies an opportunity to comment 
on information and recordkeeping requests. PHMSA specifically requests 
comments on the information collection and recordkeeping burdens 
associated with developing, implementing, and maintaining these 
proposed requirements. Address written comments to the Dockets Unit as 
identified in the ADDRESSES section of this rulemaking. We must receive 
comments regarding information collection burdens prior to the close of 
the comment period identified in the DATES section of this rulemaking. 
In addition, you may submit comments specifically related to the 
information collection burden to the PHMSA Desk Officer, Office of 
Management and Budget, at fax number 202-395-6974. 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. 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).

[[Page 50771]]

Description of Action
    Docket No. PHMSA-2013-0260 (HM-215M), 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
    This action is necessary to integrate into the HMR recent changes 
to the International Maritime Dangerous Goods Code (IMDG Code), the 
International Civil Aviation Organization's Technical Instructions for 
the Safe Transport of Dangerous Goods by Air (ICAO TI), and the United 
Nations Recommendations on the Transport of Dangerous Goods--Model 
Regulations (UN Model Regulations) effective January 1, 2015. If the 
changes in this proposed rule are not adopted in the HMR by this 
effective date, US 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 
transport regulations that could result in shippers and carriers 
segmenting domestic and international operations to accommodate 
differing requirements. The changes to the HMR contained in this 
proposed rulemaking are intended to avoid this result.
    The intended effect of this action is to align the HMR with 
international hazardous material transport standards and requirements 
to the extent practicable in accordance with Federal Hazardous 
Materials transportation law (49 U.S.C. 5210). When considering the 
adoption of international hazardous material standards under the HMR, 
PHMSA reviews and evaluates 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 public.
    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 TI. The amendments proposed in this notice are 
intended to facilitate the safe and efficient transportation of 
hazardous materials in international commerce, provide clarity to 
encourage and increase regulatory compliance, and improve the efficacy 
of emergency response in the event of a hazardous materials incident.
Alternatives
    In proposing this rulemaking, PHMSA is considering the following 
alternatives:
    No Action Alternative:
    If PHMSA chose this alternative, it would not proceed with any 
rulemaking on this subject and the current regulatory standards would 
remain in effect.
    Preferred Alternative:
    This alternative is the current proposal as it appears in this 
Notice of Proposed Rulemaking (NPRM), applying to the transportation of 
hazardous materials by various transport modes (highway, rail, vessel 
and aircraft). The proposed amendments included in this alternative are 
more fully addressed in the preamble and regulatory text sections of 
this NPRM. However, they generally include: (1) Updates to references 
to various international hazardous materials transport standards; (2) 
Amendments to the hazardous materials table to add, revise, or remove 
certain proper shipping names, packing groups, special provisions, 
packaging authorizations, bulk packaging requirements and vessel 
stowage requirements; (3) Amendments to add and delete various 
substances to the list of marine pollutants in Appendix B to Sec.  
172.101; (4) Changes throughout the Part 173 packaging requirements to 
authorize more flexibility when choosing packages for hazardous 
materials; (5) An exception from the HMR for marine pollutants up to 5 
liters (1.3 gallons) for liquids or 5 kg (11 pounds) for solids when 
these materials are packaged in accordance with the general packaging 
requirements of Sec. Sec.  173.24 and 173.24a; (6) Minimum sizes for 
the OVERPACK and SALVAGE markings; and; (7) Revisions and additions to 
vessel stowage codes listed in column 10B of the HMT and segregation 
requirements in Sec.  176.83 consistent with the IMDG Code.
No Action Alternative
    If PHMSA were to select the No Action Alternative, current 
regulations would remain in place, and no new provisions would be 
added. However, efficiencies gained through harmonization in updates to 
transport standards, lists of regulated substances, definitions, 
packagings, stowage requirements/codes, flexibilities allowed, enhanced 
markings, segregation requirements, etc., would not be realized. 
Foregone efficiencies in the No Action Alternative include freeing up 
limited resources to concentrate on vessel transport hazard 
communication (hazcom) issues of potentially much greater environmental 
impact.
    Additionally, the Preferred Alternative encompasses enhanced and 
clarified regulatory requirements, which would result in increased 
compliance and fewer environmental and safety incidents. Not adopting 
the proposed environmental and safety requirements in the NPRM under 
the No Action Alternative would result in a lost opportunity for 
reducing environmental and safety-related incidents.
    Greenhouse gas emissions would remain the same under the No Action 
Alternative.
Preferred Alternative
    If PHMSA selects the provisions as proposed in this NPRM, we 
believe that safety and environmental risks would be reduced and that 
protections to human health and environmental resources would be 
increased. Potential environmental impacts of each proposed amendment 
in the preferred alternative are discussed below:
    1. Propose updates to references to various international hazardous 
materials transport standards, including the 2015-2016 Edition of the 
ICAO TI; Amendment 37-14 to the IMDG Code; the 18th Revised Edition of 
the UN Model Regulations; Amendment 2 to the 5th revised edition of the 
UN Manual of Tests and Criteria; incorporation by reference of the 
Canadian Transportation of Dangerous Goods Regulations to include 
Amendment 11 (SOR/2011-239) October 27, 2011 and; adding two new 
references standards and update four other references to standards 
applicable to the manufacture, use, and requalification of pressure 
vessels published by the International Organization for 
Standardization:
    The HMR authorize shipments prepared in accordance with the ICAO TI 
and transported by motor vehicle either before or after being 
transported

[[Page 50772]]

by aircraft. Similarly, the HMR authorize shipments prepared in 
accordance with the IMDG Code if all or part of the transportation is 
by vessel. The authorizations to use the ICAO TI and the IMDG code are 
subject to certain conditions and limitations outlined in part 171 
subpart C. PHMSA believes that this proposed amendment, which will 
increase standardization and consistency of regulations, will result in 
greater protection of human health and the environment. Consistency 
between U.S. and international regulations enhances the safety and 
environmental protection of international hazardous materials 
transportation through better understanding of the regulations, an 
increased level of industry compliance, the smooth flow of hazardous 
materials from their points of origin to their points of destination, 
and consistent emergency response in the event of a hazardous materials 
incident.
    Enhanced environmental protection will also be achieved through 
more targeted and effective training. This proposed amendment will 
eliminate inconsistent hazardous materials regulations, which hamper 
compliance training efforts. For ease of compliance with appropriate 
regulations, air and vessel carriers engaged in the transportation of 
hazardous materials generally elect to comply with the ICAO TI and IMDG 
Code as appropriate. By maintaining consistency between these 
international regulations and the HMR, shippers and carriers are able 
to train their hazmat employees in a single set of requirements for 
classification, packaging, hazard communication, handling, stowage, 
etc., thereby minimizing the possibility of improperly preparing and 
transporting a shipment of hazardous materials because of differences 
between domestic and international regulations.
    Greenhouse gas emissions would remain the same under this proposed 
amendment.
    2. Propose amendments to the HMT to add, revise, or remove certain 
proper shipping names, packing groups, special provisions, packaging 
authorizations, bulk packaging requirements and vessel stowage 
requirements:
    PHMSA believes that this proposed amendment, which will increase 
standardization and consistency of regulations, will result in greater 
protection of human health and the environment. Consistency between US 
and international regulations enhances the safety and environmental 
protection of international hazardous materials transportation through 
better understanding of the regulations, an increased level of industry 
compliance, the smooth flow of hazardous materials from their points of 
origin to their points of destination, and consistent emergency 
response in the event of a hazardous materials incident. New and 
revised entries to the HMT reflect emerging technologies, and a need to 
better describe or differentiate between existing entries. These 
proposed changes mirror changes in the Dangerous Goods list of The 18th 
Revised Edition of the UN Model Regulations, the 2015-2016 Edition of 
the ICAO TI and the 37-14 amendments to the IMDG Code. It is extremely 
important for the domestic HMR to mirror the UN Model Regulations, the 
ICAO TI, and the IMDG Code with respect to the entries in the HMT to 
ensure consistent naming conventions across modes and international 
borders.
    Enhanced environmental protection will also be achieved through 
more targeted and effective training. This proposed amendment will 
eliminate inconsistent hazardous materials regulations, which hamper 
compliance training efforts. For ease of compliance with appropriate 
regulations, international carriers engaged in the transportation of 
hazardous materials by vessel generally elect to comply with the IMDG 
Code. By maintaining consistency between these international 
regulations and the HMR, shippers and carriers are able to train their 
hazmat employees in a single set of requirements for classification, 
packaging, hazard communication, handling, stowage, etc., thereby 
minimizing the possibility of improperly preparing and transporting a 
shipment of hazardous materials because of differences between domestic 
and international regulations.
    The packing group assignment reflects a degree of danger associated 
with a particular material and identifies appropriate packaging. 
However, assignment of a packing group is not appropriate in all cases 
(e.g. explosives, gases, radioactive material). In such cases the 
packing group does not indicate a degree of danger and the packaging 
requirements for those materials are specified in the appropriate 
section in part 173. Similarly for articles, the packing group only 
reflects the degree of the danger posed by the hazardous component, but 
may not reflect danger of the article itself, which may be 
substantially reduced or changed when compared to shipping the 
hazardous component alone. Currently and without specific rationale, 
some articles are assigned packing groups while others are not. The 
inconsistent application of packing groups to articles can create 
problems for trainers when trying to explain regulatory structure to 
students. This proposed change provides a level of consistency for all 
articles specifically listed in the HMT, without diminishing 
environmental protection and safety.
    For adsorbed gases, PHMSA proposes adding into the HMR a 
definition, HMT entries, authorized packagings and safety requirements 
including but not limited to quantity limitations and filling limits. 
PHMSA believes that this proposed amendment will result in greater 
protection of human health and the environment by facilitating the safe 
and efficient transport of gases adsorbed onto a porous media within 
cylinders. This technology allows the cylinder to be filled and 
transported with gas at sub-atmospheric pressure. Sub-atmospheric 
transport of gas minimizes potential leaks of gas during 
transportation, thus providing significant safety and environmental 
improvements over traditional high-pressure cylinders. This method of 
transporting gas is a proven safe method authorized through a PHMSA 
special permit for over ten years and recently adopted into the UN 
Model Regulations, the ICAO TI and the IMDG Code.
    Greenhouse gas emissions would remain the same under this proposed 
amendment.
    3. Propose additions and deletions of various substances to/from 
the list of Marine Pollutants in HMR, Appendix B to 172.101:
    As for the above amendments, PHMSA believes that this proposed 
amendment, which will increase standardization and consistency of 
regulations, will result in greater protection of human health and the 
environment. Consistency between US and international regulations 
enhances the safety and environmental protection of international 
hazardous materials transportation through better understanding of the 
regulations, an increased level of industry compliance, the smooth flow 
of hazardous materials from their points of origin to their points of 
destination, and consistent emergency response in the event of a 
hazardous materials incident. The proposed additions and deletions are 
based on the criteria contained in the IMDG code for substances 
classified as toxic to the aquatic environment. The HMR maintain a list 
as the basis for regulating substances toxic to the aquatic environment 
and allow use of the criteria in the IMDG Code if a listed material 
does not meet the criteria for a marine pollutant. PHMSA periodically 
updates its list based on changes to the IMDG code and evaluation of 
listed materials against the IMDG code

[[Page 50773]]

criteria. Amending the marine pollutant list will facilitate consistent 
communication of the presence of marine pollutants and facilitate safe 
and efficient transportation without imposing significant burden 
associated with characterizing mixtures as marine pollutants.
    Also similar to the above amendments, enhanced environmental 
protection will also be achieved through more targeted and effective 
training. This proposed amendment will eliminate inconsistent hazardous 
materials regulations, which hamper compliance training efforts. For 
ease of compliance with appropriate regulations, international carriers 
engaged in the transportation of hazardous materials by vessel 
generally elect to comply with the IMDG Code. By maintaining 
consistency between these international regulations and the HMR, 
shippers and carriers are able to train their hazmat employees in a 
single set of requirements for classification, packaging, hazard 
communication, handling, stowage, etc., thereby minimizing the 
possibility of improperly preparing and transporting a shipment of 
hazardous materials because of differences between domestic and 
international regulations.
    Greenhouse gas emissions would remain the same under this proposed 
amendment.
    4. Propose adopting changes throughout the HMR Part 173 packaging 
requirements to authorize more flexibility when choosing packages for 
hazardous materials:
    The proposed changes would adopt manufacturing and performance 
standards for small gas pressure receptacles without a relief device, 
clarify the use of the HMT entry ``fire extinguisher'', authorize the 
use of large salvage packagings and provide a list of authorized 
packagings for ammonium nitrate emulsions. As for the above amendments, 
PHMSA believes that these proposed amendments, which will increase 
standardization and consistency of regulations, will result in greater 
protection of human health and the environment. Consistency between US 
and international regulations enhances the safety and environmental 
protection of international hazardous materials transportation through 
better understanding of the regulations, an increased level of industry 
compliance, the smooth flow of hazardous materials from their points of 
origin to their points of destination, and consistent emergency 
response in the event of a hazardous materials incident. PHMSA proposes 
to adopt changes throughout the Part 173 packaging requirements to 
authorize more flexibility when choosing packages for hazardous 
materials. This action is consistent with amendments adopted into the 
UN Model Regulations.
    These amendments permit additional flexibility for authorized 
packages without compromising environmental protection or safety. 
Manufacturing and performance standards for small gas pressure 
receptacles ensure a safe packaging that is capable of retaining its 
contents without being overly prescriptive. The proposed clarification 
for fire extinguishers increases the transparency of the regulations, 
which will in turn result in increased compliance, reduced incidents of 
undeclared or mis-declared hazardous material and enhanced 
environmental protection and safety. Increased flexibility will also 
add to environmental protection by increasing the ease of regulatory 
compliance.
    Also similar to the above amendments, enhanced environmental 
protection will be achieved through more targeted and effective 
training. This proposed amendment will eliminate inconsistent hazardous 
materials regulations, which hamper compliance training efforts. By 
maintaining consistency between the UN Model Regulations and the HMR, 
shippers and carriers are able to train their hazmat employees in a 
single set of requirements for classification, packaging, hazard 
communication, handling, stowage, etc., thereby minimizing the 
possibility of improperly preparing and transporting a shipment of 
hazardous materials because of differences between domestic and 
international regulations.
    Greenhouse gas emissions would remain the same under this proposed 
amendment.
    5. Proposed exception from the HMR for marine pollutants up to 5 
liters (1.3 gallons) for liquids or 5 kg (11 lbs.) for solids when 
these materials are packaged in accordance with the general packaging 
requirements of Sec. Sec.  173.24 and 173.24a:
    PHMSA believes that this proposed amendment would provide for a 
slight net increase in environmental protection and safety by reducing 
confusion and simplifying multi-modal transit hazardous material 
transportation requirements. Currently, packages containing less than 5 
liters (1.3 gallons) for liquids or 5 kg (11 lbs.) of material 
containing marine pollutants are subject to additional requirements 
such as shipping papers, Class 9 labelling and UN packaging when 
offered for transport by air or vessel in accordance with the ICAO TI 
or the IMDG Code. However, these same materials would not be subject to 
the HMR when transported by motor vehicle, rail car or aircraft in the 
U.S. The presence of these labels in one mode of transport can cause 
confusion in the U.S. supply chain.
    The proposed amendment would exempt from the HMR small packages of 
hazardous material that are regulated only because of the presence of 
one or more marine pollutants. Materials in these quantities pose a low 
risk in transportation. In addition, these low quantities of materials 
present even lower risks in transportation because they often contain 
low concentrations of marine pollutant constituents. Lastly, risks of 
incidents are very low. In the past 10 years, in tens of thousands of 
vessel shipments, PHMSA's data contains only one record of marine 
pollutant released on a vessel that caused environmental damage. In 
this incident, the material was packaged in a 55-gallon drum and would 
not be impacted by the proposed amendment, since the package would 
still be required to display the marine pollutant mark and the shipping 
documents would still have to communicate the presence of a marine 
pollutant. By reducing the hazard communication (hazcom) burdens for 
lower risk commodities, industry, shippers, and transporters can focus 
hazard communication resources on areas with potentially greater 
environmental and safety consequences.
    The proposed action is consistent with recent revisions to the IMDG 
Code. PHMSA believes that this proposed amendment will increase 
standardization and consistency of regulations, may also result in 
greater protection of human health and the environment. Consistency 
between U.S. and international regulations enhances the safety and 
environmental protection of international hazardous materials 
transportation through better understanding of the regulations, an 
increased level of industry compliance, the smooth flow of hazardous 
materials from their points of origin to their points of destination, 
and consistent emergency response in the event of a hazardous materials 
incident. Excepting these quantities of marine pollutants from the HMR 
will facilitate consistent communication of the presence of marine 
pollutants and facilitate safe and efficient transportation without 
imposing significant burden associated with characterizing mixtures as 
marine pollutants.
    Also similar to the above amendments, enhanced environmental 
protection will also be achieved through

[[Page 50774]]

more targeted and effective training. This proposed amendment will 
eliminate inconsistent hazardous materials regulations, which hamper 
compliance training efforts. For ease of compliance with appropriate 
regulations, international carriers engaged in the transportation of 
hazardous materials by vessel generally elect to comply with the IMDG 
Code. By maintaining consistency between these international 
regulations and the HMR, shippers and carriers are able to train their 
hazmat employees in a single set of requirements for classification, 
packaging, hazard communication, handling, stowage, etc., thereby 
minimizing the possibility of improperly preparing and transporting a 
shipment of hazardous materials because of differences between domestic 
and international regulations.
    Greenhouse gas emissions would remain the same under this proposed 
amendment.
    6. Proposed amendments to add minimum sizes for the OVERPACK and 
SALVAGE markings. These markings would be characters at least 12 mm 
(.47 inches) high:
    PHMSA believes that this proposed amendment, which will provide for 
enhanced hazard communication, will result in greater protection of 
human health and the environment. An overpack is an enclosure to 
provide protection or convenience of handling for one or more packages 
such as pallets and crates. A salvage package is used to contain a 
damaged, leaking or non-conforming package. The HMR require these 
packages to be marked OVERPACK or SALVAGE, as appropriate. This 
communicates the nature of these specialized packaging configurations 
to package handlers and emergency responders. However, because there is 
currently no minimum size requirement for these marks, this information 
is not always readily visible. This proposed amendment would ensure 
that these hazard markings are visible, thus resulting in decreased 
incidents with impacts to the environment and safety.
    Greenhouse gas emissions would remain the same under this proposed 
amendment.
    7. Proposed amendments to revise and add vessel stowage codes 
listed in column 10B of the HMT and segregation requirements in HMR 
Sec.  176.83 consistent with the IMDG Code. These changes are designed 
to harmonize with the IMDG Code and would provide additional guidance 
on the loading and stowage of various materials. Additionally, proposed 
amendments to increase the required segregation distances between 
Division 4.3 dangerous when wet material (i.e. materials liable to give 
off a flammable or toxic gas in contact with water) and Class 3 
flammable liquids and Division 2.1 flammable gases:
    As discussed for previous amendments herein, PHMSA believes that 
this proposed amendment, which will increase standardization and 
consistency of regulations, will result in greater protection of human 
health and the environment. Consistency between U.S. and international 
regulations enhances the safety and environmental protection of 
international hazardous materials transportation through better 
understanding of the regulations, an increased level of industry 
compliance, the smooth flow of hazardous materials from their points of 
origin to their points of destination, and consistent emergency 
response in the event of a hazardous materials incident. New and 
revised entries to the HMT reflect emerging technologies, and a need to 
better describe or differentiate between existing entries. These 
proposed changes mirror the IMDG Code. It is extremely important for 
the domestic HMR and HMT to mirror the IMDG Code to ensure consistent 
naming conventions across modes and international borders.
    Enhanced environmental protection will also be achieved through 
more targeted and effective training. This proposed amendment will 
eliminate inconsistent hazardous materials regulations, which hamper 
compliance training efforts. For ease of compliance with appropriate 
regulations, international carriers engaged in the transportation of 
hazardous materials by vessel generally elect to comply with the IMDG 
Code. By maintaining consistency between these international 
regulations and the HMR, shippers and carriers are able to train their 
hazmat employees in a single set of requirements for classification, 
packaging, hazard communication, handling, stowage, etc., thereby 
minimizing the possibility of improperly preparing and transporting a 
shipment of hazardous materials because of differences between domestic 
and international regulations.
    PHMSA also believes that this group of amendments will increase 
environmental protection and safety through its increased segregation 
distance requirements and enhanced guidance, which will better prevent 
materials from contacting each other and/or water in transportation. 
Increased segregation distances prevent the mixing of incompatible 
material and the subsequent evolution of flammable or toxic gases, 
along with attendant fires and explosions. Together, stowage and 
segregation help manage the risks associated with the transport of 
hazardous materials by water. While the risk associated with the 
transport of these materials is relatively low, these measures would 
further reduce that risk and prevent the spread of a fire between 
flammable materials and materials that react dangerously with water.
    Greenhouse gas emissions would remain the same under this proposed 
amendment.
    Agencies Consulted:
    This NPRM represents PHMSA's first action in the U.S. for this 
program area. PHMSA has coordinated with the U.S. Federal Aviation 
Administration and the U.S. Coast Guard, in the development of this 
proposed rule. PHMSA will consider the views expressed in comments to 
the NPRM submitted by members of the public, state and local 
governments, and industry.
    Conclusion:
    The provisions of this proposed rule build on current regulatory 
requirements to enhance the transportation safety and security of 
shipments of hazardous materials transported by highway, rail, aircraft 
and vessel, thereby reducing the risks of an accidental or intentional 
release of hazardous materials and consequent environmental damage. 
PHMSA believes the net environmental impact will be positive. PHMSA 
believes that there are no significant environmental impacts associated 
with this proposed rule.
    PHMSA welcomes any views, data, or information related to 
environmental impacts that may result if the proposed requirements are 
adopted, as well as possible alternatives and their environmental 
impacts.

K. Executive Order 13609 and International Trade Analysis

    Under E.O. 13609, agencies must consider whether the impacts 
associated with significant variations between

[[Page 50775]]

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.

    The additions and revisions read as follows:

Sec.  172.101  Purpose and use of the hazardous materials table.

* * * * *
    (f) Column 5: Packing group. Column 5 of the HMT specifies one or 
more packing groups assigned to a material corresponding to the proper 
shipping name and hazard class for that material. Class 2, Class 7, 
Division 6.2 (other than regulated medical wastes), and ORM-D 
materials, do not have packing groups. Articles in other than Class 1 
are not assigned to packing groups. For packing purposes, any 
requirement for a specific packaging performance level is set out in 
the applicable packing authorizations of part 173. Packing Groups I, II 
and III indicate the degree of danger presented by the material is 
either great, medium or minor, respectively. If more than one packing 
group is indicated for an entry, the packing group for the hazardous 
material is determined using the criteria for assignment of packing 
groups specified in subpart D of part 173. When a reevaluation of test 
data or new data indicates a need to modify the specified packing 
group(s), the data should be submitted to the Associate Administrator. 
Each reference in this column to a material which is a hazardous waste 
or a hazardous substance, and whose proper shipping name is preceded in 
Column 1 of the Table by the letter ``A'' or ``W'', is modified to read 
``III'' on those occasions when the material is offered for 
transportation or transported by a mode in which its transportation is 
not otherwise subject to requirements of this subchapter.
* * * * *
    (k) Column 10: Vessel stowage requirements. Column 10A [Vessel 
stowage] specifies the authorized stowage locations on board cargo and 
passenger vessels. Column 10B [Other provisions] specifies codes for 
stowage and handling requirements for specific hazardous materials. 
Hazardous materials offered for transportation as limited quantities 
are allocated stowage category A and are not subject to the stowage 
codes assigned by column 10B. The meaning of each code in Column 10B is 
set forth in Sec.  176.84 of this subchapter. Section 176.63 of this 
subchapter sets forth the physical requirements for each of the 
authorized locations listed in Column 10A. (For bulk transportation by 
vessel, see 46 CFR parts 30 to 40, 70, 98, 148, 151, 153 and 154.) The 
authorized stowage locations specified in Column 10A are defined as

    28 The dihydrated sodium salt of dichloroisocyanuric acid does not 
meet the criteria for inclusion in Division 5.1 (Oxidizer) and is not 
subject to the requirements of this subchapter unless meeting the 
criteria for inclusion in another class or division.
* * * * *
    52 This entry may only be used for substances that are too 
insensitive for acceptance into Class 1 (explosive) when tested in 
accordance with Test Series 2 in the UN Manual of Tests and Criteria, 
Part I (incorporated by reference; see Sec.  171.7 of this subchapter).
* * * * *
    147 This entry applies to non-sensitized emulsions, suspensions, 
and gels consisting primarily of a mixture of ammonium nitrate and 
fuel, intended to produce a Type E blasting explosive only after 
further processing prior to use. The mixture for emulsions typically 
has the following composition: 60-85% ammonium nitrate; 5-30% water; 2-
8% fuel; 0.5-4% emulsifier or thickening agent; 0-10% soluble flame 
suppressants; and trace additives. Other inorganic nitrate salts may 
replace part of the ammonium nitrate. The mixture for suspensions and 
gels typically has the following composition: 60-85% ammonium nitrate; 
0-5% sodium or potassium perchlorate; 0-17% hexamine nitrate or 
monomethylamine nitrate; 5-30% water; 2-15% fuel; 0.5-4% thickening 
agent; 0-10% soluble flame suppressants; and trace additives. Other 
inorganic nitrate salts may replace part of the ammonium nitrate. These 
substances must satisfactorily pass Tests 8(a), (b) and (c) of Test 
Series 8 of the UN Manual of Tests and Criteria, Part I, Section 18 
(IBR, see Sec.  171.7 of this subchapter), and may not be classified 
and transported unless approved by the Associate Administrator.

    160 This entry applies to safety devices for vehicles, vessels or 
aircraft, e.g. air bag inflators, air bag modules, seat-belt 
pretensioners, and pyromechanical devices containing Class 1 
(explosive) materials or materials of other hazard classes. These 
articles must be tested in accordance with Test series 6(c) of Part I 
of the UN Manual of Tests and Criteria (incorporated by reference; see 
Sec.  171.7 of this subchapter), with no explosion of the device, no 
fragmentation of device casing or pressure vessel, and no projection 
hazard nor thermal effect that would significantly hinder fire-fighting 
or other emergency response efforts in the immediate vicinity. If the 
air bag inflator unit satisfactorily passes the series 6(c) test, it is 
not necessary to repeat the test on the air bag module. This entry does 
not apply to life saving appliances described in Sec.  173.219 (UN2990 
and UN3072).

    238 Neutron radiation detectors:
    a. Neutron radiation detectors containing non-pressurized boron 
trifluoride gas in excess of 1 gram and radiation detection systems 
containing such neutron radiation detectors as components may be 
transported by highway, rail, vessel, or cargo aircraft in accordance 
with the following:
    (1) Each radiation detector must meet the following conditions:
    (i) The pressure in each neutron radiation detector must not exceed 
105 kPa absolute at 20 [deg]C;
    (ii) The amount of gas must not exceed 13 grams per detector;
    (iii) Each neutron radiation detector must be of welded metal 
construction with brazed metal to ceramic feed through assemblies. 
These detectors must have a minimum burst pressure of 1800 kPa as 
demonstrated by design type qualification testing; and
    (iv) Each detector must be tested to a 1 x 10-\10\ 
cm\3\/s leaktightness standard before filling.
    (2) Radiation detectors transported as individual components must 
be transported as follows:
    (i) They must be packed in a sealed intermediate plastic liner with 
sufficient absorbent material to absorb the entire gas contents.
    (ii) They must be packed in strong outer packagings and the 
completed package must be capable of withstanding a 1.8 meter (6-foot) 
drop without leakage of gas contents from detectors.
    (iii) The total amount of gas from all detectors per outer 
packaging must not exceed 52 grams.
    (3) Completed neutron radiation detection systems containing 
detectors meeting the conditions of paragraph (a)(1) of this special 
provision must be transported as follows:
    (i) The detectors must be contained in a strong sealed outer 
casing;
    (ii) The casing must contain include sufficient absorbent material 
to absorb the entire gas contents;
    (iii) The completed system must be packed in strong outer 
packagings capable of withstanding a 1.8 meter (6-foot) drop test 
without leakage unless a system's outer casing affords equivalent 
protection.
    b. Except for transportation by aircraft, neutron radiation 
detectors and radiation detection systems containing such detectors 
transported in accordance with paragraph (a) of this special provision 
are not subject to the

    342 Glass inner packagings (such as ampoules or capsules) intended 
only for use in sterilization devices, when containing less than 30 mL 
of ethylene oxide per inner packaging with not more than 300 mL per 
outer packaging, may be transported in accordance with Sec.  173.4a of 
this subchapter, irrespective of the restriction of Sec.  173.4a(b) and 
the indication of ``forbidden'' in columns (9A) and (9B) of the Sec.  
172.101 table provided that:
    a. After filling, each glass inner packaging must be determined to 
be leak-tight by placing the glass inner packaging in a hot water bath 
at a temperature and for a period of time sufficient to ensure that an 
internal pressure equal to the vapor pressure of ethylene oxide at 55 
[deg]C is achieved. Any glass inner packaging showing evidence of 
leakage, distortion or other defect under this test must not be

with a propellant that meets the definition of a gas in Sec.  173.115. 
A chemical under pressure packaged in an aerosol dispenser must be 
transported under UN1950. The chemical under pressure must be classed 
based on the hazard characteristics of the components in the 
propellant; the liquid; or the solid. The following provisions also 
apply:
    a. If one of the components, which can be a pure substance or a 
mixture, is classed as flammable, the chemical under pressure must be 
classed as flammable in Division 2.1. Flammable components are 
flammable liquids and liquid mixtures, flammable solids and solid 
mixtures or flammable gases and gas mixtures meeting the following 
criteria:
    (1) A flammable liquid is a liquid having a flashpoint of not more 
than 93 [deg]C (200 [deg]F);
    (2) A flammable solid is a solid that meets the criteria in Sec.  
173.124 of this subchapter; or
    (3) A flammable gas is a gas that meets the criteria in Sec.  
173.115 of this subchapter.
    b. Gases of Division 2.3 and gases with a subsidiary risk of 5.1 
must not be used as a propellant in a chemical under pressure.
    c. Where the liquid or solid components are classed as Division 
6.1, Packing Group II or III, or Class 8, Packing Group II or III, the 
chemical under pressure must be assigned a subsidiary risk of Division 
6.1 or Class 8 and the appropriate identification number must be 
assigned. Components classed as Division 6.1, Packing Group I, or Class 
8, Packing Group I, must not be offered for transportation and 
transported under this description.

hexafluoride may be classified under this entry only if the conditions 
of Sec. Sec.  173.420(a)(4) and (a)(6), 173.420 (d), 173.421(a)(2) and 
(a)(4), and, for fissile-excepted material, the conditions of 173.453 
are met. In addition to the provisions applicable to the transport of 
Class 8 substances, the provisions of Sec. Sec.  173.421(a)(3), and 
173.443(a) apply. In addition, packages shall be legibly and durably 
marked with an identification of the consignor, the consignee, or both. 
No Class 7 label is required to be displayed. The consignor shall be in 
possession of a copy of each applicable certificate when packages 
include fissile material excepted by competent authority approval. When 
a consignment is undeliverable, the consignment shall be placed in a 
safe location and the appropriate competent authority shall be informed 
as soon as possible and a request made for instructions on further 
action. If it is evident that a package of radioactive material, or 
conveyance carrying unpackaged radioactive material, is leaking, or if 
it is suspected that the package, or conveyance carrying unpackaged 
material, may have leaked, access to the package or conveyance must be 
restricted and, as soon as possible, the extent of contamination

and the resultant radiation level of the package or conveyance must be 
assessed. The scope of the assessment must include, as applicable, the 
package, the conveyance, the adjacent loading and unloading areas, and, 
if necessary, all other material which has been carried in the 
conveyance. When necessary, additional steps for the protection of 
persons, property, and the environment must be taken to overcome and 
minimize the consequences of such leakage. Packages, and conveyances 
carrying unpackaged material, which are leaking radioactive contents in 
excess of limits for normal conditions of transport may be removed to 
an interim location under supervision, but must not be forwarded until 
repaired or reconditioned and decontaminated, or as approved by the 
Associate Administrator.

33. Section 173.166 is revised to read as follows:

Sec.  173.166  Safety devices.

    For the purpose of this section, safety devices are articles which 
contain pyrotechnic substances or hazardous materials of other classes 
and are used in vehicles, vessels or aircraft to enhance safety to 
persons. Examples are: air bag inflators, air bag modules, seat-belt 
pretensioners and pyromechanical devices. Pyromechanical devices are 
assembled components for tasks such as but not limited to separation, 
locking, or release-and-drive or occupant restraint. The term includes 
``Safety devices, pyrotechnic''.
    (a) Definitions. An air bag inflator (consisting of a casing 
containing an igniter, a booster material, a gas generant and, in some 
cases, a pressure receptacle (cylinder)) is a gas generator used to 
inflate an air bag in a supplemental restraint system in a motor 
vehicle. An air bag module is the air bag inflator plus an inflatable 
bag assembly. A seat-belt pretensioner contains similar hazardous 
materials and is used in the operation of a seat-belt restraining 
system in a motor vehicle.
    (b) Classification. (1) Safety devices, excluding those which 
contain flammable or toxic gases or mixtures thereof, may be classed as 
Class 9 (UN3268) if the safety device, or if more than a single safety 
device is involved then the representative of the maximum parameters of 
each design type, is examined and successfully tested by a person or 
agency who is authorized by the Associate Administrator to perform 
examination and testing of explosives under Sec.  173.56(b)(1), and 
who:
    (i) Does not manufacture or market explosives or safety devices, is 
not owned in whole or in part, or is not financially dependent upon any 
entity that manufactures or markets explosives or safety devices;
    (ii) Performs all examination and testing in accordance with the 
applicable requirements as specified in special provision 160 (see 
Sec.  172.102 of this subchapter); and
    (iii) Maintains records in accordance with paragraph (g) of this 
section.

[[Page 50825]]

    (iv) By adhering to all the provisions specified in paragraph 
(b)(1) of this section, a Class 9 (UN3268) air bag inflator, air bag 
module or seat-belt pretensioner design is not required to be submitted 
to the Associate Administrator for approval or assigned an EX number. 
All other Class 9 (UN3268) safety device designs are required to be 
submitted to the Associate Administrator for approval and assigned an 
EX number;
    (2) A safety device may be classed as Division 1.4G if the maximum 
parameters of each design type has been examined and successfully 
tested by a person or agency who is authorized by the Associate 
Administrator to perform such examination and testing of explosives 
under Sec.  173.56(b)(1). As a Class 1 explosive, the manufacturer must 
submit to the Associate Administrator a report of the examination and 
assignment of a recommended shipping description, division, and 
compatibility group, and if the Associate Administrator finds the 
approval request meets the regulatory criteria, the explosive may be 
approved in writing and assigned an EX number; or
    (3) The manufacturer has submitted an application, including a 
classification issued by the competent authority of a foreign 
government to the Associate Administrator, and received written 
notification from the Associate Administrator that the device has been 
approved for transportation and assigned an EX number.
    (c) EX numbers. (1) When a safety device is offered for 
transportation, the shipping paper must contain the EX number or 
product code for each approved device in association with the basic 
description required by Sec.  172.202(a) of this subchapter. Product 
codes must be traceable to the specific EX number assigned to the 
device by the Associate Administrator. Further, if the EX number or 
product code is contained on the shipping paper then it is not required 
to be marked on the outside package.
    (2) An air bag inflator, air bag module or seat-belt pretensioner, 
when classed as a Class 9 (UN3268) under the terms of paragraph (b)(1) 
of this section, is excepted from the EX number requirements of this 
paragraph (c).
    (d) Exceptions. (1) A safety device that is classed as a Class 9 
(UN3268) under the terms of paragraph (b)(1) of this section and is 
installed in a motor vehicle, aircraft, boat or other transport 
conveyance or its completed components, such as steering columns or 
door panels, is not subject to the requirements of this subchapter. A 
safety device that has been classed as a Division 1.4G and approved by 
the Associate Administrator and is installed in a motor vehicle, 
aircraft, boat or other transport conveyance or its completed 
components, such as steering columns or door panels, is not subject to 
the requirements of this subchapter.
    (2) An air bag module containing an inflator that has been 
previously approved by the Associate Administrator for transportation 
is not required to be submitted for further examination or approval. 
For classifications granted after July 30, 2013, if the Class 9 
designation for the inflator is contingent upon packaging or other 
special means specified by the authorized testing agency, the modules 
must be tested and certified separately to determine if they can be 
shipped as ``UN3268, Safety Devices, 9, PG III''.
    (3) An air bag module containing an inflator that has previously 
been approved by the Associate Administrator as a Division 2.2 material 
is not required to be submitted for further examination to be reclassed 
as a Class 9 material.
    (4) Shipments to recycling or waste disposal facilities. When 
offered for domestic transportation by highway, rail freight, cargo 
vessel or cargo aircraft, a serviceable safety device classed as either 
Class 9 (UN3268) or Division 1.4G removed from a motor vehicle that was 
manufactured as required for use in the United States may be offered 
for transportation and transported without compliance with the shipping 
paper requirement prescribed in paragraph (c) of this section. However, 
when these articles are shipped to a recycling facility, the word 
``Recycled'' must be entered on the shipping paper immediately after 
the basic description prescribed in Sec.  172.202 of this subchapter. 
No more than one device is authorized in the packaging prescribed in 
paragraph (e)(1), (2), or (3) of this section. The device must be 
cushioned and secured within the package to prevent movement during 
transportation.
    (5) An air bag inflator, air bag module, or seat-belt pretensioner 
that was classed and approved for transportation prior to January 1, 
2015 may continue to be transported under the terms of the existing 
approval, using the appropriate proper shipping name ``Safety Devices'' 
or ``Safety Devices, Pyrotechnic'' based on the classification of the 
device as assigned by PHMSA or the authorized person or agency that 
examined and tested the design type.
    (e) Packagings. Rigid, outer packagings, meeting the general 
packaging requirements of part 173 are authorized as follows. 
Additionally, the UN specification packagings listed in paragraphs 
(e)(1) through (3) of this section must meet the packaging 
specification and performance requirements of part 178 of this 
subchapter at the Packing Group III performance level. The packagings 
must be designed and constructed to prevent movement of the articles 
and inadvertent activation. Further, if the Class 9 designation is 
contingent upon packaging specified by the authorized testing agency,

and indicated that they have understood the restrictions on hazardous 
materials in baggage.
    (c) Check-in. When the flight check-in process is conducted 
remotely (e.g., via the Internet) or when completed at the airport, 
without assistance from another person (e.g., automated check-in 
kiosk), the aircraft operator must ensure that information on the types 
of hazardous materials a passenger is forbidden to transport aboard an 
aircraft is presented to passengers. Information may be in text or in 
pictorial form but must be such that the check-in process cannot be 
completed until the passenger, or a person acting on their behalf, has 
been presented with this information and indicated that they have
