Hazardous Materials: Revision to Requirements for the 
Transportation of Batteries and Battery-Powered Devices; and 
Harmonization With the United Nations Recommendations, International 
Maritime Dangerous Goods Code, and International Civil Aviation 
Organization's Technical Instructions

AGENCY: Pipeline and Hazardous Materials Safety Administration (PHMSA), 
DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: PHMSA proposes 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 the Hazardous Materials 
Regulations with recent changes to the International Maritime Dangerous 
Goods Code, the International Civil Aviation Organization's Technical 
Instructions for the Safe Transport of Dangerous Goods by Air, and the 
United Nations Recommendations on the Transport of Dangerous Goods.
    The proposals include amendments and clarifications addressing the 
safe transportation of batteries and battery-powered devices. 
Consistent with recent changes to the International Civil Aviation 
Organization's Technical Instructions, PHMSA is proposing to clarify 
the prohibition against transporting electrical devices, including 
batteries and battery-powered devices that are likely to create sparks 
or generate a dangerous amount of heat. PHMSA also is proposing to 
modify and enhance requirements for the packaging and handling of 
batteries and battery-powered devices, particularly in air commerce, to 
emphasize the safety precautions that are necessary to prevent 
incidents during transportation. PHMSA developed these proposals in 
conjunction with the Federal Aviation Administration in order to 
enhance the safe transportation of batteries and battery-powered 
devices.

I. Background

    By final order published December 21, 1990 (Docket HM-181; 55 FR 
52402), we comprehensively revised the Hazardous Materials Regulations 
(HMR; 49 CFR parts 171 to 180) to harmonize U.S. requirements with the 
United Nations Recommendations on the Transport of Dangerous Goods (UN 
Recommendations). The UN Recommendations are not regulations, but 
rather are recommendations issued by the UN Committee of Experts on the 
Transport of Dangerous Goods (TDG) and the Globally Harmonized System 
of Classification and Labelling of Chemicals (GHS). These 
recommendations are amended and updated biennially by the TDG and serve 
as the basis for national, regional, and international modal 
regulations, including the International Maritime Organization's 
International Maritime Dangerous Goods Code (IMDG Code) and 
International Civil Aviation Organization Technical Instructions (ICAO 
TI) for the Transport of Dangerous Goods by Air.
    Since publication of the 1990 rule, we have issued seven additional 
international harmonization rules (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; and HM-215I, 71 FR 78595) based on 
the corresponding biennial updates of the UN Recommendations, the IMDG 
Code, and the ICAO TI.
    To maintain alignment of the HMR with international requirements, 
in this NPRM, we are proposing to incorporate

[[Page 44805]]

changes based on the Fifteenth revised edition of the UN 
Recommendations, Amendment 34 to the IMDG Code, and the 2009-2010 ICAO 
TI which become effective January 1, 2009.
    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 in order to promote safety or other overriding public 
interest, but otherwise requires PHMSA to align the HMR with 
international transport standards and requirements to the extent 
practicable (see 49 U.S.C. 5120). Harmonization facilitates 
international trade by minimizing the costs and other burdens of 
complying with multiple or inconsistent safety requirements for 
transportation of hazardous materials to and from the United States and 
becomes increasingly important as the volume of hazardous materials 
transported in international commerce grows. By facilitating 
compliance, harmonization also tends to enhance safety for 
international movements, but only if the international standards 
themselves provide an appropriate level of safety. To that end, PHMSA 
actively participates in the development of international standards for 
the transportation of hazardous materials, frequently advocating the 
adoption in international standards of particular HMR requirements. 
When considering the adoption of international standards under the HMR, 
we review and consider each amendment on its own merit. Each amendment 
is considered 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.

II. Transportation of Batteries and Battery-Powered Equipment, Articles 
and Devices

A. Current Regulatory Requirements

    The most significant proposals in this NPRM address the 
transportation of batteries and battery-powered devices. Currently 
batteries and battery-powered devices are subject to a number of 
requirements in the HMR. Most importantly, the HMR restrict the 
transportation of electrical devices, including batteries and battery-
powered devices, that are likely to create sparks or generate a 
dangerous amount of heat that could cause fire, smoke, or otherwise 
adversely affect the packaging material or means of conveyance. These 
batteries and battery-powered devices are forbidden from transportation 
unless packaged in a manner that prevents such an occurrence (Sec.  
173.21(c)). Additionally, the following types of batteries are subject 
to packaging and hazard communication requirements:
     Wet (electric storage) batteries (Sec.  173.159);
     Batteries containing sodium (Sec.  173.189);
     Lithium cells and batteries (Sec.  173.185);
     Solid potassium hydroxide batteries (Sec.  173.213); and
     Battery-powered vehicles and equipment (Sec.  173.220).
    These requirements primarily address the hazards posed by the 
chemicals contained in the batteries as opposed to the stored 
electrical energy. For instance, wet cell batteries are required to be 
packaged in a manner to prevent leakage of the corrosive battery fluid 
in the event of an accident. The electrical hazard of the battery is 
addressed through general requirements to prevent short-circuiting, and 
the general prohibition on transporting such devices without proper 
protection and packaging (Sec.  173.21(c)). But the HMR currently 
prescribes no separate or unique classification for identifying 
materials that present a hazard in transport based on their stored 
electrical energy. This proposed rule will address the electrical 
hazards posed by batteries and battery-powered devices by enhancing 
packaging and hazard communication requirements.

B. Accident/Incident History

    A growing number of incidents involving batteries and battery-
powered devices transported by aircraft (see Section II.B) has 
highlighted the transportation safety risks. Additionally, several 
factors are contributing to a heightened concern for the future 
transport of these devices, with particular attention to the risk 
onboard aircraft, including: (1) The increasing number of batteries and 
battery-powered portable and handheld devices (e.g., laptops, cellular 
phones, etc.) carried by airline passengers and otherwise transported 
in commerce; (2) the development and use of batteries with extended 
operating life and greater stored energy; and (3) the increasing number 
of counterfeit batteries in distribution and use. If not adequately 
protected from damage, short circuiting or, for devices containing 
batteries, inadvertent activation, batteries and battery-powered 
devices of all types can create or cause sparks or a dangerous amount 
of heat for extended periods, and in some cases, cause a fire. Cargo 
fires are a significant hazard in all modes of transportation and can 
have particularly catastrophic results in air transportation. If 
located aboard an aircraft during flight, inadequately protected 
batteries and battery-powered devices can pose a significant threat to 
the safety of people, property, and the environment.
    PHMSA and the Federal Aviation Administration (FAA) are aware of 
more than 90 incidents involving batteries or battery-powered devices 
in air transportation since 1996 that produced smoke, fire or a 
dangerous amount of heat. These incidents have occurred either on board 
an aircraft in cargo, checked, or carry-on baggage, or in ground 
transport facilities associated with air transportation. Many of these 
incidents involved shipments of batteries as cargo. The remainder 
involved shipments of electrically powered vehicles, equipment, or 
apparatus containing batteries. Since most batteries are excepted from 
the incident reporting requirements in the HMR, it is likely there have 
been additional incidents in all modes of transportation that were not 
reported.
    One major injury and several minor injuries were reported from 
these incidents. In some cases, the property damage and business 
interruption costs resulting from the incidents were significant. Most 
incidents occurred or were discovered on the ground in air transport 
facilities or vehicles. Three incidents occurred in flight on passenger 
and cargo planes, resulting in emergency landings or flight plan 
diversions.

C. Recent Actions To Enhance Battery Safety

    In response to these incidents, PHMSA's predecessor agency (the 
Research and Special Programs Administration) issued a public advisory 
on July 7, 1999 (64 FR 36743), reminding the transportation industry 
and public that batteries and electric devices that contain batteries 
are forbidden for transport unless properly packaged to prevent the 
creation of sparks or generation of a dangerous amount of heat (Sec.  
173.21). The FAA issued safety advisories to the airline industry on 
July 2, 1999, and again on May 23, 2002.
    In response to a series of incidents involving batteries carried by 
airline passengers, PHMSA initiated a campaign to educate the public 
about ways to reduce the risks posed in the transportation of batteries 
and battery-

[[Page 44806]]

powered devices. The campaign included establishing a dedicated Web 
page for air travelers and developing a battery safety guide that 
includes safety measures and tips for the general public, for 
distribution at airports, in retail outlets, and through electronic 
media. As part of our battery safety campaign, we recommended various 
practical measures for complying with the regulations and reducing 
transportation risks. Recommended practices include keeping batteries 
installed in electronic devices; packing spare batteries individually 
in carry-on baggage; keeping spare batteries in their original retail 
packaging; separating batteries from other metallic objects, such as 
keys, coins and jewelry; securely packing battery-powered devices in a 
manner to prevent accidental activation; and ensuring batteries are 
undamaged and purchased from reputable sources. On March 26, 2007, 
PHMSA issued a safety advisory notice (72 FR 14167) to further inform 
the traveling public and airline employees about the importance of 
properly packing and handling batteries and battery-powered devices 
when they are carried on board an aircraft.
    We have also initiated a comprehensive strategy aimed at reducing 
the risks posed by batteries and battery-powered devices in 
transportation. On February 22, 2007; April 26, 2007; May 24-25, 2007; 
and April 11, 2008, PHMSA hosted meetings with public and private 
sector stakeholders who share our concern for the safe transportation 
of batteries and battery-powered devices. The meetings provided an 
opportunity for representatives of the National Transportation Safety 
Board (NTSB), the Consumer Product Safety Commission, manufacturers of 
batteries and battery-powered devices, airlines, airline employee 
organizations, testing laboratories, and the emergency response and law 
enforcement communities to share and disseminate information about 
battery-related risks and developments. Understanding these risks is 
essential to promote improvements in industry standards and best 
practices. Together we identified a series of immediate and longer-term 
actions that participants are taking or will take to enhance safety, 
including:
     Comprehensive reporting and investigation of battery-
related incidents;
     Improved battery, consumer product, and software design;
     Development and implementation of a technical standards 
agenda;
     Consideration and implementation of improved regulatory 
standards;
     Focused enforcement; and
     Development and implementation of a public outreach and 
education campaign.
    The new requirements proposed in this NPRM are an important element 
of the safety strategy, designed to address specific battery-related 
hazards not adequately addressed by existing HMR requirements.

D. Proposals To Enhance the Safe Transportation of Batteries

    In this NPRM, we propose the following provisions to enhance the 
safe transportation of batteries and battery-powered devices:
     Require reporting of incidents involving batteries and 
battery-powered devices (devices include equipment) or vehicles.
     Clarify the requirement that batteries, and battery-
powered devices and vehicles, be offered for transportation and 
transported in a manner that prevents short-circuiting, dangerous 
evolution of heat, damage to terminals, and, in the case of 
transportation by aircraft, unintentional activation.
     Require a certification on the shipping documentation that 
batteries and battery-powered devices have met the conditions and all 
requirements for transport as specified in the applicable exception or 
special provision.
     Eliminate the requirement to disconnect the terminals when 
a battery-powered wheelchair or mobility aid is transported as checked 
baggage, provided the wheelchair or mobility aid design provides an 
effective means of preventing unintentional activation.
    The measures proposed in this rule will harmonize the HMR with 
international standards applicable to the transportation of batteries 
and battery-powered devices. More importantly, these measures will 
provide data and information to develop an understanding of the root 
causes of battery incidents in transportation and reduce the associated 
risks.
1. Prevention of Short Circuits, Dangerous Evolution of Heat, Sparks, 
Unintentional Activation, or Damage to Terminals
    In this NPRM, we are proposing a number of revisions to clarify 
that batteries of all types and battery-powered devices, equipment, and 
vehicles must be packaged for transportation in a manner that prevents 
short-circuiting, damage to terminals, dangerous evolution of heat, 
and, for transportation by aircraft, unintentional activation. We are 
also proposing several examples of packaging methods that may meet this 
performance standard, including packaging each battery or each battery-
powered device in fully enclosed inner packagings made of non-
conductive material, and separating batteries and battery-powered 
devices in a manner to prevent contact with other batteries, devices or 
conductive materials (e.g., metal) in the packagings. Batteries 
designed with exposed terminals or connectors should have the exposed 
terminals or connectors individually protected with non-conductive 
caps. We propose to include language in Sec. Sec.  171.15, 171.16, 
173.21, 173.159, 173.220, and 175.10 to further clarify these 
requirements.
2. Incident Reporting
    Since most batteries are currently excepted from the incident 
reporting requirements in the HMR, it is likely that numerous incidents 
involving batteries and battery-powered devices in all modes of 
transportation that have gone un-reported. This under-reporting has 
made it difficult to assess the full extent of incidents in 
transportation and their causes. Therefore, in this NPRM, we propose to 
require the reporting in accordance with Sec. Sec.  171.15 and 171.16 
of the HMR of all incidents involving shipments of batteries or 
battery-powered devices involving fire, violent rupture, explosion, or 
a dangerous evolution of heat. The proposed reporting requirement 
applies to all battery shipments, including batteries that are prepared 
and offered as excepted from HMR requirements. The proposed incident 
reporting requirement is consistent with incident reporting provisions 
recently adopted by ICAO. (See Sec. Sec.  171.15 and 171.16.)
3. Batteries Installed in Equipment
    The HMR include a number of provisions applicable to batteries 
installed in vehicles, machinery, or other types of equipment. Section 
173.220 sets forth transportation requirements for internal combustion 
engines, self-propelled vehicles, mechanical equipment containing 
internal combustion engines, and battery powered vehicles or equipment. 
Generally, this section excepts battery-powered vehicles, machinery, 
and equipment from the HMR, provided they meet certain minimal 
requirements. We are aware of several incidents resulting in a 
dangerous evolution of heat initiated by batteries of this design which 
have been inadequately protected. In this NPRM, we propose to require 
battery-powered vehicles, machinery, and equipment,

[[Page 44807]]

including battery-powered wheelchairs and mobility aids, to conform to 
the new requirements being proposed in Sec.  173.159, including 
requirements for protecting terminals and preventing short-circuiting 
and unintentional activation. In addition, we propose to clarify that 
battery-powered vehicles, machinery, and equipment are forbidden to be 
transported unless packaged in a manner preventing the creation of 
sparks, a dangerous amount of heat and, in air transportation, 
unintentional activation.
    Section 175.10 sets forth exceptions for passengers, crewmembers, 
and air operators. Currently, the HMR permit a wheelchair or other 
battery-powered mobility device to be carried on board a passenger 
aircraft as checked baggage provided that (1) visual inspection, 
including removal of the battery if necessary, reveals no obvious 
defects; (2) the battery is disconnected and terminals are insulated to 
prevent short-circuiting; and (3) the battery is securely attached to 
the wheelchair or mobility device or removed and separately packaged. 
We are concerned, however, that repeated handling of the battery in a 
wheelchair or other mobility device could result in damage or other 
problems that could compromise safety. Moreover, the design for 
batteries and their housing has significantly improved in recent years. 
Therefore, in this NPRM, we propose to revise paragraph Sec.  
175.10(a)(15) to eliminate the current requirement to disconnect the 
terminals when a battery-powered wheelchair or other mobility device is 
transported as checked baggage provided the device provides an 
effective means of preventing unintentional activation. Battery 
terminals must continue to be protected from short-circuiting, but such 
protection is inherent in the design of most wheelchairs and mobility 
devices. This proposal will enhance safety while providing improved 
accommodation for passengers traveling with wheelchairs or mobility 
devices and is consistent with corresponding provisions in the ICAO TI.
4. Non-Spillable Batteries
    Section 173.159 sets forth requirements for the transportation of 
wet batteries, including non-spillable batteries. As currently provided 
in Sec.  173.159(d), non-spillable batteries are excepted from the HMR 
provided certain conditions are met. Unless all of the conditions 
specified in Sec.  173.159(d) are met, the non-spillable battery is 
fully subject to the HMR as a wet electric storage battery. 
International regulations outline the conditions in which a battery can 
be considered non-spillable and provide packaging requirements specific 
to non-spillable batteries. Non-spillable batteries meeting additional 
requirements are excepted from all other requirements of the HMR. In 
this NPRM, we are proposing to describe in Sec.  173.159(f) the 
conditions in which a battery can be considered non-spillable and 
relocate the exceptions pertaining to non-spillable batteries to a new 
Sec.  173.159a. Consistent with international requirements, we are 
proposing to specify that batteries can be considered ``non-
spillable,'' provided they are capable of passing a vibration test and 
a pressure differential test without leakage. We are also proposing to 
require non-spillable batteries to be packaged in strong outer 
packaging and securely fastened in the battery holder or the equipment 
when the battery is an integral part of the operation of mechanical or 
electronic equipment. In addition, we propose to specify that except 
for the incident reporting requirements of Sec. Sec.  171.15 and 
171.16, non-spillable batteries are not subject to the requirements of 
the HMR if they meet the following additional conditions:
     At a temperature of 55 [deg]C (131 [deg]F), the battery 
does not contain any unabsorbed free-flowing liquid, and must be 
designed so that electrolyte will not flow from a ruptured or cracked 
case;
     The battery must be protected against short-circuiting and 
securely packaged in strong outer packaging;
     The battery must be marked ``NONSPILLABLE'' or 
``NONSPILLABLE BATTERY''; and
     For transportation by aircraft;
     They must meet the provisions of Sec.  173.159(b); and
     Indicate that all conditions for transport as specified in 
the applicable exception or special provision have been met with the 
words, ``not restricted'' on the airway bill. This indication will 
allow freight forwarders and operators to verify that the consignor is 
aware of, and has complied with, the applicable regulatory 
requirements.
5. Conforming Amendments
    We propose a number of conforming amendments in this NPRM to ensure 
that batteries are transported in accordance with the proposed 
requirements in Sec.  173.159. For example, Sec.  173.21(c) currently 
prohibits the transportation of electrical devices unless packaged to 
prevent the creation of sparks or generation of a dangerous amount of 
heat. In this NPRM, we propose to revise this paragraph to clarify that 
the term ``electrical devices'' includes ``batteries'' and ``battery-
powered devices.'' We also propose to revise Special provision 130 to 
specify that ``Batteries, dry, sealed, n.o.s.'' are not subject to the 
requirements of the HMR except those pertaining to incident reporting, 
short circuit protection, damage to terminals, prevention of a 
dangerous amount of heat, damage to terminals, and when transported by 
aircraft, unintentional activation and an indication on the air waybill 
that all conditions for transport have been met (Special provision 
130).
    In addition, we are proposing to amend certain entries in the 
Hazardous Materials Table (HMT) in Sec.  172.101. Currently, under the 
HMR, dry batteries are not subject to incident reporting or measures to 
prevent unintentional activation until a dangerous amount of heat has 
developed. As indicated above, in this NPRM, we propose to extend the 
requirements for incident reporting and enhanced packaging to cover all 
batteries and battery-powered devices. Thus, we propose to remove the 
entry ``Batteries, dry, not subject to the requirements of this 
subchapter'' in favor of a new entry, `''Batteries, dry, sealed, 
n.o.s.''
    Note that shippers must distinguish between the proper shipping 
name ``Batteries, dry, sealed, n.o.s.,'' and the existing proper 
shipping name ``Batteries, wet, non-spillable, electric storage.'' 
Batteries described as ``Batteries, wet, non-spillable, electric 
storage'' have metallic lead and lead oxide electrodes and sulfuric 
acid electrolytes just like regular ``wet'' batteries, but the acid is 
either gelled up with silica or absorbed in a mat of micro-glass 
fibers. These batteries are not truly ``sealed'' (non-spillable) but 
are ``valve regulated'' (they are technically termed ``valve-regulated 
lead-acid'' or ``VRLA''). The resealable valves prevent the entrance of 
oxygen from the outside air, but release excess hydrogen and oxygen 
formed during overcharging. These types of batteries are generally used 
for 12-volt vehicular starting applications and uninterruptible power 
supply applications.
    Batteries described under the proposed new proper shipping name 
``Batteries, dry, sealed, n.o.s'' are hermetically ``sealed'' and 
generally utilize other metals and/or carbon as electrodes. These 
batteries are typically used for portable power applications. The 
rechargeable (and some nonrechargeable) types have gelled alkaline 
electrolytes (rather than acidic) making it difficult for them to 
generate hydrogen or oxygen when overcharged.

[[Page 44808]]

    The entry ``Batteries, dry, containing potassium hydroxide solid, 
electric storage'' would be revised by adding to column (7) a reference 
to proposed new Special provision ``237.'' The new special provision 
would specify that, for transportation by aircraft, ``Batteries, dry, 
containing potassium hydroxide solid, electric storage'' must be 
prepared and packaged in accordance with the requirements of Sec.  
173.159(a), and for transportation by aircraft, Sec.  173.159(b)(2). 
The entry ``Batteries, wet, non-spillable, electric storage'' would be 
revised by adding to column (8A), a reference to proposed new Sec.  
173.159a.
    Section 173.189 sets forth transportation requirements for 
batteries containing sodium or cells containing sodium. In this NPRM, 
we propose to revise paragraph (e) to specify that vehicles, machinery 
and equipment powered by sodium batteries must be consigned under the 
entry ``Battery-powered vehicle or Battery-powered equipment.''
    Section 176.84 contains additional stowage and segregation 
requirements for hazardous materials on cargo and passenger vessels. In 
this NPRM, in order to fully align the HMR with the IMDG Code, a new 
vessel stowage code ``146'' is added to the Sec.  176.84(b) table to 
specify that, ``Category B stowage applies for unit loads in open cargo 
transport units.'' The new vessel stowage code ``146'' is assigned to 
``Batteries, wet, filled with acid, electric storage,'' UN2794 and 
``Batteries, wet, filled with alkali, electric storage,'' UN2795 in 
column (10B) of the HMT.
6. Lithium Batteries
    Except for incident reporting requirements, this NPRM does not 
propose any amendments pertaining to the transportation of lithium 
batteries. PHMSA is working to evaluate and reduce lithium battery 
risks through targeted enforcement; inspections and testing, including 
root cause investigation of all incidents; public outreach; and other 
non-regulatory initiatives.
    As we identify other opportunities for safety improvement, further 
rulemaking may be necessary. Before developing additional rulemaking 
proposals, PHMSA plans to complete an assessment of the costs and 
benefits of further restrictions and available alternatives. In the 
meantime, we will continue to monitor and evaluate the safety 
performance of lithium batteries in transportation, identify and target 
counterfeit and other non-conforming batteries, and encourage the 
development and introduction of safer battery designs.

III. Additional Harmonization Proposals in This NPRM

    In addition to the battery proposals detailed above, in this NPRM, 
we are proposing the following amendments to harmonize the HMR with the 
most recent revisions to the UN Recommendations, ICAO TI, and IMDG 
Code:
     Hazardous Materials Table (HMT): Amendments to the 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 
limitations and vessels stowage provisions.
     Fuel Cells: Amendments to the HMT to add four new proper 
shipping names to describe the range of fuel used in fuel cell 
cartridges: (1) Corrosive substances (UN3477); (2) liquefied flammable 
gas (UN3478); (3) hydrogen in metal hydride (UN3479); and (4) water-
reactive substances (UN3476). In addition, we are proposing amendments 
to expand the types of fuel cell cartridges permitted in carry-on 
baggage to include water-reactive substances and hydrogen in a metal 
hydride. Amendments to Sec.  173.230 provide packaging requirements for 
fuel cells and, except for transportation by aircraft, limited quantity 
exceptions for the various types of fuel cell cartridges specified 
above.
     Small Quantity Exceptions: Amendments maintaining current 
allowances for small quantities of Division 2.2, Class 3, Division 4.1, 
Division 4.2 (PG II and III), Division 4.3 (PG II and III), Division 
5.1, Division 5.2, Division 6.1, Class 7, Class 8, and Class 9 
materials transported by highway and rail and adopting the UN and ICAO 
excepted quantity provisions for transportation by aircraft or vessel.
     Incident Reporting: Amendments to provisions that except 
certain hazardous materials or commodities from the requirements of the 
HMR, including incident reporting requirements. The HMR contain 
overriding provisions in Sec. Sec.  171.15 and 171.16 requiring notice 
of specific types of incidents to the National Response Center (NRC) 
and submission of a Hazardous Materials Incident Report, DOT Form F 
5800.1, when in possession of a hazardous material at the time of an 
incident. We would amend several provisions to emphasize the need to 
provide notice to the NRC and to address the need to obtain more 
accurate and complete data on incidents. The NRC relies on notices to 
gather and distribute spill data to emergency responders, and the DOT 
hazardous materials transportation safety program relies on DOT Form F 
5800.1 to gather basic information on incidents that occur during 
transportation.
     Organic Peroxide Tables: Amendments to the Organic 
Peroxide Tables to add, revise, or remove certain hazardous materials 
and provisions.
     Incorporation by Reference: Amendments to incorporate by 
reference the updated ICAO TI, IMDG Code, and UN Recommendations.
     Hazard Communication on Air waybills: Amendments to 
require the consignor to indicate on the ``air waybill'' that certain 
hazardous materials or articles have met the conditions for transport 
as specified in the applicable exception or special provision.
     Petitions for Rulemaking: We are addressing several 
petitions for rulemaking: P-1490, requesting PHMSA to remove the 
requirement that the type of package must be included on the 
notification of pilot-in-command; P-1494, requesting PHMSA to specify 
that pictograms described in the UN GHS are not prohibited under the 
HMR; P-1505, requesting PHMSA to include a new proper shipping name 
``Powder, smokeless,'' UN0509, to the Sec.  172.101 HMT and to include 
the new entry among the explosives assigned Packaging Instruction 
114(b) in Sec.  173.62; and P-1516, requesting PHMSA to allow the 
marine pollutant list to remain the basis in domestic transportation 
for regulating substances hazardous to the environment while permitting 
substances meeting the new IMDG Code criteria to be transported as 
substances hazardous to the environment. We are also addressing 
petitions P-1517 and P-1518, requesting PHMSA to align provisions for 
the transport of fuel cell systems and cartridges in the HMR with 
international standards.
     Requirements for Marine Pollutants: Recently, the 
classification criteria for marine pollutants in the IMDG Code were 
amended for consistency with the aquatic toxicity criteria adopted 
within the GHS. The HMR currently allow materials meeting the criteria 
of a marine pollutant under the prior IMDG Code criteria to be 
classified as such for domestic or international transportation (see 
paragraph 4 of the introduction to Appendix B of 172.101). The new 
classification system adopted into the IMDG Code is complicated, and 
the associated criteria for classifying mixtures containing marine 
pollutants would involve an additional layer of complexity without a 
corresponding

[[Page 44809]]

public benefit; therefore, we are not proposing to adopt the new IMDG 
Code environmental classification system. In this rulemaking, we are 
proposing to maintain the current regulatory approach to facilitate 
transportation without mandating use of the new GHS-based criteria. We 
also propose to adopt a new marking for marine pollutants consistent 
with the marking adopted within the IMDG Code. These actions will 
provide the greatest possible harmonization with international 
requirements without imposing an undue burden on industry. This 
proposal is also consistent with a Petition for Rulemaking (P-1516) 
filed by the Dangerous Goods Advisory Council (DGAC). DGAC requested 
that for domestic transportation the marine pollutant list be 
maintained as the basis for regulating substances hazardous to the 
environment while permitting a substance meeting the new IMDG Code 
criteria to be transported as a substance hazardous to the aquatic 
environment. DGAC also recommended that the current 10% rule for 
classifying mixtures containing marine pollutants be used while 
allowing compliance with the mixture calculation in the IMDG Code. 
Though we have not proposed to implement a 10% rule for marine 
pollutants irrespective of whether they are identified as a severe 
marine pollutant, we request comments on that recommendation. In 
particular, we are interested in the environmental impacts of such a 
change and its effect on human health and the environment. We invite 
comments on the practical consequences of the differing approaches, for 
instance, in the event of release of such substances into aquatic 
resources and drinking water.

IV. Amendments Not Being Considered for Adoption in This NPRM

    This NPRM proposes changes to the HMR based on amendments to the 
Fifteenth revised edition of the UN Recommendations, Amendment 34 to 
the IMDG Code, and the 2009-2010 ICAO TI, which become effective 
January 1, 2009. However, we are not proposing to adopt all of the 
amendments to those documents 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 handled, or will be handling, 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, does not require substantive changes 
from the international standard on which it is based, and imposes 
minimal or no cost impacts on persons subject to the requirement. 
Otherwise, in order to provide opportunity for notice and comment, the 
change must be proposed in an NPRM.
    One of the goals of this rulemaking is to continue to maintain 
consistency between the HMR and the international requirements. We are 
not striving to make the HMR identical to the international regulations 
but rather to remove or avoid potential barriers to international 
transportation.
    Below is a listing of those 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:
     Requirements for Hazardous Materials Security. The UN and 
ICAO have adopted minimal requirements pertaining to hazardous 
materials security. On March 25, 2003, we published a final rule to 
enhance the security of hazardous materials transported in commerce (68 
FR 14510). In the final rule, shippers and carriers of certain highly 
hazardous materials are required to develop and implement security 
plans. In addition, all shippers and carriers of hazardous materials 
are required to include a security component. The security plan 
requirements apply to shipments of hazardous materials that must be 
placarded and to select agents. In a separate rulemaking, we are 
considering revising the list of materials for which security plans are 
required to ensure that the requirements apply only to those materials 
that pose a true security risk in transportation. See the advance 
notice of proposed rulemaking (ANPRM) published on September 21, 2006 
(71 FR 55156).
     Requirements for Radioactive Materials. We are not 
proposing to adopt provisions pertaining to the transportation of Class 
7 (radioactive) materials. Amendments to requirements pertaining to the 
transportation of Class 7 (radioactive) materials are based on changes 
contained in the International Atomic Energy Agency (IAEA) publication, 
``IAEA Safety Standards: Regulations for the Safe Transport of 
Radioactive Materials.'' Due to their complexity, these changes are 
being addressed in a separate rulemaking under Docket HM-250.
     Requirements for Infectious Substances. The UN and ICAO 
have adopted minimal standards applicable to the transportation of 
human remains and animal carcasses as to which there is minimal 
likelihood that pathogens are present. For purposes of the HMR, such 
specimens are not considered hazardous, and their transportation is not 
subject to the HMR. These specimens are currently regulated by the Food 
and Drug Administration of the U.S. Department of Health and Human 
Services, the U.S. Department of Agriculture and subject to State and 
local authorities. Therefore, we are not proposing to incorporate the 
new international provisions into the HMR.
     Requirement for Definition of ``Target'' for Use During 
Packaging Testing. Amendments to the HMR pertaining to the definition 
of a ``target'' for a drop test performed on non-bulk packagings are 
not being proposed in this rulemaking. The UN Recommendations amended 
the description to specify that the surface of a target must be 
immovable, free of defects, rigid, and large enough to ensure that the 
test package falls entirely upon the surface. We believe the current 
provisions in the HMR pertaining to the drop test method for non-bulk 
packagings adequately address this issue.
     Requirement for Vibration Test for All Intermediate Bulk 
Containers (IBCs). Amendments to the HMR pertaining to the test method 
and duration of a vibration test for IBCs are not being proposed in 
this rulemaking. PHMSA successfully helped to introduce to the UN 
Recommendations a vibration test requirement for IBCs that would both 
enhance safety and help to establish a more equivalent testing protocol 
for manufacturers of IBCs worldwide. However, the vibration test 
adopted by the UN may be conducted as a ``stand-alone'' design-type 
test on an otherwise untested IBC. In contrast, the vibration test 
originally introduced by PHMSA would require the vibration test to be 
conducted in sequence with other required tests. We believe this method 
provides a higher degree of safety, and therefore, are not proposing to 
amend the vibration test requirements currently in the HMR.
     Requirement for Bromine (UN1744). In the Fifteenth edition 
of the UN Recommendations, a packing instruction and a special packing 
provision for ``Bromine,'' UN1744 were consolidated into a new packing 
instruction specifically for Bromine. After reviewing this new packing

[[Page 44810]]

instruction, we believe the current provisions in the HMR pertaining to 
the packaging of Bromine are adequate.
     Exceptions to Packaging for Paint and Paint-Related 
Material. Amendments authorizing certain exceptions from performance 
testing of packagings containing paint and certain paint-related 
materials are not being proposed in this rulemaking. Currently, both 
the UN Recommendations and the HMR contain certain packaging exceptions 
for specific adhesives, printing inks, printing ink related materials, 
paint, paint-related materials and resin solutions (see UN Packing 
Instruction P001, Special Packing Provision PP1 and 49 CFR 
173.173(b)(2)). The Fifteenth revised edition of the UN Recommendations 
expands the exceptions to also include such materials when classified 
as environmentally hazardous substances. We are currently reviewing the 
incident data related to these exceptions, and may consider this issue 
for a future rulemaking.
     Requirements for Lithium Batteries. Amendments to the HMR 
pertaining to lithium batteries based on the Fifteenth revised edition 
of the UN Recommendations are not being proposed in this rulemaking. We 
are reviewing these requirements and may consider them for a future 
rulemaking.
     Requirements for Additional Signage. Amendments to the HMR 
pertaining to additional signage in airports are not being proposed in 
this rulemaking. We are reviewing these amendments, including the 
related cost impacts, and may consider them for a future rulemaking. We 
request comments to provide information and suggestions that we can use 
during a future review.

V. Section-by-Section Review

    Following is a section-by-section review of the amendments proposed 
in this NPRM. Note that this section-by-section review excludes the 
proposals applicable to the transportation of batteries and battery-
powered devices, which are detailed in Section II of this Notice. We 
request comments providing information and suggestions that we can use 
during the review of these proposals.

Part 171

Section 171.7
    The ``National Technology Transfer and Advancement Act of 1996'' 
directs agencies to use voluntary consensus standards. According to the 
Office of Management and Budget (OMB), Circular A-119, ``Federal 
Participation in the Development and Use of Voluntary Consensus 
Standards and in Conformity Assessment Activities,'' government 
agencies must use voluntary consensus standards wherever practical in 
the development of regulations. Agency adoption of industry standards 
promotes productivity and efficiency in government and industry, 
expands opportunities for international trade, conserves resources, 
improves health 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 standards bodies. PHMSA regularly reviews updated consensus 
standards and considers their merit for inclusion in the HMR.
    Section 171.7 lists all standards incorporated by reference into 
the HMR. For this rulemaking, we evaluated updated international 
consensus standards pertaining to proper shipping names, hazard 
classes, packing groups, special provisions, packaging authorizations, 
air transport quantity limitations, and vessel stowage requirements and 
determined that the revised standards provide an enhanced level of 
safety without imposing significant compliance burdens. These standards 
have a well-established and documented safety history; their adoption 
will maintain the high safety standard currently achieved under the 
HMR. Therefore, we propose to update the incorporation by reference 
materials for the ICAO TI, the IMDG Code, and the UN Recommendations. 
The updated editions of these standards become effective January 1, 
2009.
    We propose to revise the following standards:
     The Technical Instructions for the Safe Transport of 
Dangerous Goods by Air, 2007-2008 Edition.
     International Convention for the Safety of Life at Sea 
(SOLAS) Amendments 2000, Chapter II-2, Regulation 19, 2001.
     The International Maritime Organization's International 
Maritime Dangerous Goods Code, 2006 Edition, Incorporating Amendment 
33-06, English Edition, Volumes 1 and 2.
     The UN Recommendations on the Transport of Dangerous 
Goods, Fourteenth revised edition (2005), Volumes I and II.
Section 171.14
    This section lists specific transition periods for certain 
provisions adopted into the HMR. Paragraph (d) of this section 
specifies transition provisions for previously adopted amendments 
intended to harmonize the HMR with international standards. We are 
proposing revisions to this paragraph to provide specific transitional 
provisions for certain amendments proposed in this NPRM. We are 
proposing an effective date of January 1, 2009, and a mandatory 
compliance date of January 1, 2010. We propose to permit voluntary 
compliance as of January 1, 2009, to correspond with the effective 
implementation dates of the 2009-2010 ICAO TI and Amendment 34 of the 
IMDG Code. This authorization would allow shippers to prepare their 
international shipments in accordance with international standards that 
will become effective on January 1, 2009.
Section 171.25
    Section 171.25 specifies additional requirements for the use of the 
IMDG Code when a hazardous material is offered for transportation to, 
from, or within the United States by vessel, and by motor carrier and 
rail, provided all or part of the movement is by vessel. Recently, an 
incident occurred in which a portable tank containing ``Argon, 
refrigerated liquid (cryogenic liquid),'' UN1951, stowed below the deck 
of a vessel released its contents, resulting in the asphyxiation deaths 
of three individuals who entered the confined cargo space where the 
portable tank was stowed. The HMR currently prohibit the stowage of 
such materials below deck (Sec.  176.76(g)) because of the potential 
hazard of asphyxiation when large volumes of refrigerated liquefied 
gases are released below the deck of a vessel in confined spaces. 
However, the IMDG Code does not prohibit the stowage of tanks below 
deck in all cases. Some refrigerated liquefied gases, including argon, 
are assigned to stowage ``Category B'' in column (16) of the dangerous 
goods list of the IMDG Code. Therefore, in this NPRM, we propose to 
revise Sec.  171.25 to specify that portable tanks, cargo tanks, and 
tank cars containing cryogenic liquids must be ``on deck'' regardless 
of the stowage authorized in the IMDG Code.

Part 172

Section 172.101 Hazardous Materials Table (HMT)
    Section 172.101 contains the HMT and explanations for each of its 
columns. We propose to make various amendments to the HMT. Readers 
should review all changes for a complete understanding of the proposed 
amendments. For purposes of the Government Printing Office's 
typesetting procedures, proposed

[[Page 44811]]

changes to the HMT will appear under three sections of the Table, 
``remove,'' ``add,'' and ``revise.'' Certain entries in the HMT, such 
as those with proposed revisions to the proper shipping names, will 
appear as a ``remove'' and ``add.'' Proposed amendments to the HMT for 
the purpose of harmonizing with international standards include, but 
are not limited to, the following:
    In the final rule for Docket HM-215G (69 FR 76044; December 20, 
2004), we added new generic entries for Organometallic substances 
consistent with descriptions added to the UN Recommendations. In the 
final rule, we allowed the continued use of certain specific 
Organometallic entries; however, we anticipated removing the specific 
Organometallic entries from the HMT by January 1, 2007. The entries 
were to be removed because they were superseded by more appropriate 
generic entries. However, the entries intended to be removed currently 
remain in the HMT. Therefore, we are proposing to remove the following 
Organometallic entries for consistency with the intent of HM-215G:

UN3052 Aluminum alkyl halides, liquid
UN3461 Aluminum alkyl halides, solid
UN3076 Aluminum alkyl hydrides
UN3051 Aluminum alkyls
UN1366 Diethylzinc
UN1370 Dimethylzinc
UN2445 Lithium alkyls, liquid
UN3433 Lithium alkyls, solid
UN3053 Magnesium alkyls
UN2005 Magnesium diphenyl

    Special provision ``TP12'' states: ``This material is considered 
highly corrosive to steel.'' The phrase ``highly corrosive to steel'' 
is not defined by any specific criteria. Further, ``TP12,'' unlike 
other TP codes, is simply a statement and does not apply any regulatory 
requirement. It is unclear if all highly corrosive materials are 
assigned Special provision ``TP12,'' or if this statement provides any 
useful guidance for selecting an appropriate portable tank. Therefore, 
we are proposing to revise the following entries by removing Special 
provision ``TP12'':

UN1716 Acetyl bromide
UN1717 Acetyl chloride
UN2584 Alkyl sulfonic acids, liquid or Aryl sulfonic acids, liquid 
with more than 5 percent free sulfuric acid
UN2571 Alkyl sulfuric acids

NA9269 Trimethoxysilane

    We propose to add a new non-bulk packaging section (Sec.  173.206) 
for the transportation of certain flammable, corrosive and toxic 
materials, specifically, chlorosilanes that have water-reactive 
properties. For a detailed summary of the rationale, see the preamble 
discussion for Sec.  173.206. The following entries would be revised in 
Column (8B) by replacing the current non-bulk packaging provision with 
``206'':

UN1724 Allyltrichlorosilane, stabilized
UN1728 Amyltrichlorosilane
UN1747 Butyltrichlorosilane
UN1753 Chlorophenyltrichlorosilane
UN2986 Chlorosilanes, corrosive, flammable, n.o.s.
UN2987 Chlorosilanes, corrosive, n.o.s.
UN2985 Chlorosilanes, flammable, corrosive, n.o.s.
UN3362 Chlorosilanes, toxic, corrosive, flammable, n.o.s.
UN3361 Chlorosilanes, toxic, corrosive, n.o.s.
UN1762 Cyclohexenyltrichlorosilane
UN1763 Cyclohexyltrichlorosilane
UN2434 Dibenzyldichlorosilane
UN1766 Dichlorophenyltrichlorosilane
UN1767 Diethyldichlorosilane
UN1162 Dimethyldichlorosilane
UN1769 Diphenyldichlorosilane
UN1771 Dodecyltrichlorosilane
UN2435 Ethylphenyldichlorosilane
UN1196 Ethyltrichlorosilane
UN1781 Hexadecyltrichlorosilane
UN1784 Hexyltrichlorosilane
UN2437 Methylphenyldichlorosilane
UN1250 Methyltrichlorosilane
UN1799 Nonyltrichlorosilane
UN1800 Octadecyltrichlorosilane
UN1801 Octyltrichlorosilane
UN1804 Phenyltrichlorosilane
UN1816 Propyltrichlorosilane
UN1298 Trimethylchlorosilane
UN1305 Vinyltrichlorosilane, stabilized

    For consistency in the assignment of Special provision ``TP13'' 
(which requires provision of self-contained breathing apparatus when 
transported by vessel) to all chlorosilanes, the following entries 
would be revised in Column (7) by adding Special provision ``TP13'':

UN2987 Chlorosilanes, corrosive, n.o.s
UN1781 Hexadecyltrichlorosilane
UN1804 Phenyltrichlorosilane
UN1818 Silicon tetrachloride

    We consider Special provision ``TP7'' essential for the safe 
transport of chlorosilanes. This special provision requires the vapor 
space to be purged of air by nitrogen or other means. However, there is 
no consistent assignment of ``TP7'' to chlorosilanes.

[[Page 44812]]

For enhanced safety and consistency with international regulations, the 
following entries would be revised in Column (7) by adding Special 
provision ``TP7'':

UN3362 Chlorosilanes, toxic, corrosive, flammable, n.o.s.
UN3361 Chlorosilanes, toxic, corrosive, n.o.s.
UN1250 Methyltrichlorosilane
UN1305 Vinyltrichlorosilane, stabilized

    Chlorosilanes of Class 3 and Class 8 are currently authorized for 
transport in metal IBCs under Special provisions ``IB1'' and ``IB2.'' 
Because metal IBCs have lift-up lids with clamp screws, we are 
concerned that the overturn of a metal IBC during an accident may lead 
to an opening of a lift-up lid and result in a release of chlorosilanes 
from these packagings. To address these concerns, we are proposing to 
prohibit the use of metal IBCs by removing the respective ``IB1'' or 
``IB2'' provisions from the following entries. We are also proposing to 
add Special provision ``TP7'' to require the vapor space to be purged 
of air, as discussed above:

UN2986 Chlorosilanes, corrosive, flammable, n.o.s.
UN2987 Chlorosilanes, corrosive, n.o.s.
UN2985 Chlorosilanes, flammable, corrosive, n.o.s.

    Bottom discharge openings are currently allowed on portable tanks 
used for the transport of most chlorosilanes. For example, some 
chlorosilane entries are assigned Special provision ``T7,'' which 
provides for bottom opening requirements. As part of a voluntary 
initiative to enhance safety, portions of the regulated community have 
begun to use only portable tanks without bottom discharge connections. 
To further enhance safety and to prohibit the use of portable tanks 
with bottom discharge openings, we are proposing to revise the 
following entries by replacing Special provision ``T7'' with ``T10.'' 
Special provision ``T10'' prohibits the use of bottom discharge 
openings. We are also proposing to delete the respective IBC special 
provisions (as indicated below) to prohibit the use of metal IBCs and 
add Special provision ``TP7'' to require the vapor space to be purged 
of air, as discussed above:

UN1724 Allyltrichlorosilane, stabilized
UN1728 Amyltrichlorosilane
UN1747 Butyltrichlorosilane
UN1753 Chlorophenyltrichlorosilane
UN1762 Cyclohexenyltrichlorosilane
UN1763 Cyclohexyltrichlorosilane
UN2434 Dibenzyldichlorosilane
UN1766 Dichlorophenyltrichlorosilane
UN1767 Diethyldichlorosilane
UN1162 Dimethyldichlorosilane
UN1769 Diphenyldichlorosilane
UN1771 Dodecyltrichlorosilane
UN2435 Ethylphenyldichlorosilane
UN1196 Ethyltrichlorosilane
UN1781 Hexadecyltrichlorosilane
UN1784 Hexyltrichlorosilane
UN2437 Methylphenyldichlorosilane
UN1799 Nonyltrichlorosilane
UN1800 Octadecyltrichlorosilane
UN1801 Octyltrichlorosilane
UN1804 Phenyltrichlorosilane
UN1816 Propyltrichlorosilane
UN1298 Trimethylchlorosilane

    As a safety measure for the transport of most chlorosilanes, we are 
proposing to apply Special provision ``T10,'' to prohibit bottom 
discharge openings on portable tanks used to transport chlorosilanes. 
However, for chlorosilanes meeting the criteria of Division 4.3 and for 
``n.o.s.'' entries meeting the criteria for Classes 3, 8 and Division 
6.1 that have been assigned ``T10,'' we are considering the general 
assignment of Special provision ``T14'' rather than ``T10.'' In 
addition to prohibiting bottom outlet openings, Special provision 
``T14'' requires a higher minimum test pressure for the periodic 
hydrostatic pressure test. We believe a higher minimum test pressure 
would provide an increased level of safety when transporting these 
types of chlorosilanes in portable tanks. Some chlorosilanes meeting 
the above classification criteria (e.g., UN2987 and UN1295) have 
already been assigned Special provision ``T14.'' Therefore, to enhance 
safety and for consistency in assigning special provisions, we are 
proposing to revise the following entries by replacing Special 
provision ``T10'' with Special provision ``T14'' in Column (7):

UN2988 Chlorosilanes, water-reactive, flammable, corrosive, n.o.s.
UN1183 Ethyldichlorosilane
UN1242 Methyldichlorosilane

    The following entries would be revised by assigning PG II in column 
(5) rather than PG I. The flammability properties (i.e., the 
flashpoint) place them in PG II, and no additional evidence indicates 
the entries are more corrosive than all the other chlorosilanes classed 
as a Class 3, subsidiary Class 8, PG II (e.g., UN1126). Therefore, in 
accordance with the Precedence of hazard table (Sec.  173.2a), the 
entries would be classed as Class 3, subsidiary Class 8, PG II 
materials. In addition, as discussed above, we would replace Special 
provision ``T7'' with ``T10'' for most chlorosilanes, however, for 
these entries Special provision ``T10'' would replace the previously 
assigned Special provision ``T11.'' Readers should note, this revision 
is contingent upon the adoption of the proposed change from PG I to PG 
II. The entries would be revised in Column (5) by assigning PG II and 
in Column (7) by replacing Special provision ``T11'' with Special 
provision ``T10'':

UN1250 Methyltrichlorosilane
UN1305 Vinyltrichlorosilane, stabilized

    As discussed above, for most chlorosilanes, we are proposing to 
replace Special provision ``T7'' with ``T10,'' which prohibits bottom 
discharge openings. In addition, we propose to revise the following 
entries by replacing Special provision ``T11'' with Special provision 
``T14'' which prohibits bottom discharge openings in portable tanks:

UN2986 Chlorosilanes, corrosive, flammable, n.o.s.
UN2985 Chlorosilanes, flammable, corrosive, n.o.s.
UN3362 Chlorosilanes, toxic, corrosive, flammable, n.o.s
UN3361 Chlorosilanes, toxic, corrosive, n.o.s.

    Chlorosilanes of Division 6.1 are authorized for transport in metal 
IBCs under Special provision ``IB1.'' As discussed above, we are 
proposing to prohibit the use of metal IBCs for the transport of 
chlorosilanes. Additionally, Special provision ``TP27'' is recommended 
for chlorosilanes assigned Special provision ``T14.'' If found 
acceptable according to the test pressure definition in Sec.  178.274, 
Special provision ``TP27'' allows a test pressure of 4 bar instead of 6 
bar. We would assign tank provision ``TP27'' to all ``n.o.s.'' entries 
of Classes 3, 8 and Division 6.1. Entries for Division 4.3 would not be 
assigned ``TP27'' because of higher risk of a possible release of a 
flammable gas. The following entries would be revised in Column (7) by 
deleting Special provision ``IB1'' and adding Special provision 
``TP27'':

UN3362 Chlorosilanes, toxic, corrosive, flammable, n.o.s
UN3361 Chlorosilanes, toxic, corrosive, n.o.s.

    The following entries would be revised by adding Special provision 
``IP2'' to correct an inconsistency. ``Chloroacetic acid, solid,'' 
UN1751 is the only Division 6.1, PG II material assigned Special 
provision ``IB8'' that is not also assigned Special provision ``IP2.'' 
Similarly, the remaining entries listed below are Division 5.1, PG II 
materials assigned ``IB8'' but not ``IP2''. The following entries would 
be revised in Column (7) by adding Special provision ``IP2'':

UN1751 Chloroacetic acid, solid
UN1463 Chromium trioxide, anhydrous.
UN2465 Dichloroisocyanuric acid, dry or Dichloroisocyanuric acid 
salts
UN1473 Magnesium bromate

[[Page 44813]]

UN2627 Nitrites, inorganic, n.o.s.
UN1484 Potassium bromate
UN1485 Potassium chlorate
UN1487 Potassium nitrate and sodium nitrite mixtures
UN1488 Potassium nitrite
UN1490 Potassium permanganate
UN1493 Silver nitrate
UN1494 Sodium bromate
UN1495 Sodium chlorate
UN3247 Sodium peroxoborate, anhydrous
UN2468 Trichloroisocyanuric acid, dry
UN1512 Zinc ammonium nitrite
UN1514 Zinc nitrate

    Special provision ``36'' places net quantity limits per package for 
medicines classed as hazardous materials. However, the quantity limits 
are inconsistent with the net quantity packaging limits authorized 
under the limited quantities exceptions authorized for these materials. 
Therefore, these entries would be revised in Column (7) by removing 
Special provision ``36'':

UN3248 Medicine, liquid, flammable, toxic, n.o.s.
UN1851 Medicine, liquid, toxic, n.o.s.
UN3249 Medicine, solid, toxic, n.o.s.

    Chemical oxygen generators are subject to stringent packaging and 
shipping requirements. We are proposing to add a new Special provision 
``62'' to the following entries to emphasize that chemical oxygen 
generators are not authorized to be transported under the generic 
``oxidizer, n.o.s.'' entries.

UN3098 Oxidizing liquid, corrosive, n.o.s.
UN3139 Oxidizing liquid, n.o.s.
UN3099 Oxidizing liquid, toxic, n.o.s.
UN3085 Oxidizing solid, corrosive, n.o.s.
UN3137 Oxidizing solid, flammable, n.o.s.
UN1479 Oxidizing solid, n.o.s.
UN3100 Oxidizing solid, self-heating, n.o.s.
UN3087 Oxidizing solid, toxic, n.o.s.
UN3121 Oxidizing solid, water-reactive, n.o.s.

    The following entries would be revised by adding a reference to 
packaging section ``307'' to Column (8A) for consistency with 
international regulations regarding exception from the HMR for 
manufactured articles and apparatuses containing minimal amounts of 
inert gas. See the discussion of changes to Sec.  173.307 for 
additional information regarding this proposed change.

UN1006 Argon, compressed
UN1046 Helium, compressed
UN1970 Krypton, compressed
UN1065 Neon, compressed
UN2036 Xenon, compressed

    The entry ``Batteries, dry, containing potassium hydroxide solid, 
electric storage'' would be revised by adding to column (7) a reference 
to proposed new Special provision ``237.''
    The entries ``Boron trifluoride,'' UN1008, and ``Hydrogen iodide, 
anhydrous'' UN2197, would be revised by adding the Class 8 subsidiary 
hazard label to Column (6) for consistency with international 
regulations and for consistency with all other Division 2.3 toxic gas 
entries in the HMT that also have the Class 8 subsidiary hazard.
    The entry ``Calcium manganese silicon,'' UN2844 would be revised in 
Column (7) by removing Special provision ``IP2.'' When this material is 
transported in other than metal or rigid plastic IBCs, Special 
provision ``IP2'' specifies they must be transported in a closed 
freight container or a closed transport vehicle. However, this is 
inconsistent with other Division 4.3, PG III materials that are not 
subject to this Special IBC packaging provision.
    For consistency with UN Recommendations, the entry ``Chlorine,'' 
UN1017, would be revised in Column (6) by adding the Division 5.1 
subsidiary hazard label. This label will help communicate that this 
material may cause or enhance the combustion of other materials.
    The hazardous materials descriptions for the entries 
``Chloronitrobenzene, liquid ortho,'' UN3409, and 
``Chloronitrobenzenes, solid meta or para,'' UN1578, would be revised 
in Column (2) by removing the italicized word(s). The italicized 
word(s) associated with the proper shipping names are a potential 
source of confusion and would be removed for clarification and 
consistency with the same entries in the UN Recommendations. This 
revision appears as a ``Remove/Add'' in this rulemaking.
    The entries ``Environmentally hazardous substances, liquid, 
n.o.s.,'' UN3082 and ``Environmentally hazardous substances, solid, 
n.o.s.,'' UN3077, would be revised by adding a new Special provision 
``335'' in Column (7). Special provision ``335'' clarifies that 
mixtures of non-hazardous solids and environmentally hazardous liquids 
or solids may be classified as UN3077 provided there is no free liquid 
visible at the time the substance is loaded or at the time the 
packaging or transport unit is closed.
    In addition to flammable liquid fuel cell cartridges already 
provided for by the HMR, a number of other rapidly advancing fuel cell 
technologies employing a range of fuels continue to emerge. In this 
NPRM, we are proposing to revise the entry for fuel cells containing a 
flammable liquid (UN3473) to include fuel cell cartridges containing a 
flammable liquid packed with or contained in equipment, and to add four 
new proper shipping names to the HMT to describe the range of fuel used 
in fuel cell cartridges. These entries are (1) water-reactive 
substances (UN3476); (2) corrosive substances (UN3477); (3) liquefied 
flammable gas (UN3478); and (4) hydrogen in metal hydride (UN3479). 
Readers should note that liquefied flammable gases and hydrogen in a 
metal hydride are both Division 2.1 materials used in fuel cell 
cartridges. However, the provisions necessary for the safe 
transportation of these articles are quite different and therefore, it 
is necessary to distinguish them with separate shipping descriptions.
    A new entry ``Fuel cell cartridges or Fuel cell cartridges 
contained in equipment or Fuel cell cartridges packed with equipment, 
containing corrosive substances,'' UN3477, would be added.
    The proper shipping name for the entry ``Fuel cell cartridges, 
containing flammable liquids,'' UN3473, would be revised in Column (2) 
to read ``Fuel cell cartridges or Fuel cell cartridges contained in 
equipment or Fuel cell cartridges packed with equipment, containing 
flammable liquids.'' This revision appears as a ``Remove/Add'' in this 
rulemaking.
    A new entry ``Fuel cell cartridges or Fuel cell cartridges 
contained in equipment or Fuel cell cartridges packed with equipment, 
containing hydrogen in metal hydride,'' UN3479, would be added.
    A new entry ``Fuel cell cartridges or Fuel cell cartridges 
contained in equipment or Fuel cell cartridges packed with equipment, 
containing liquefied flammable gas,'' UN3478, would be added.
    A new entry ``Fuel cell cartridges or Fuel cell cartridges 
contained in equipment or Fuel cell cartridges packed with equipment, 
containing water-reactive substances,'' UN3476, would be added.
    The entry ``Gasohol,'' NA1203, would be revised in Column (7) by 
adding Special provision ``177'' to indicate that mixtures of gasoline 
and ethanol with less than 10 percent ethanol for use in internal 
combustion engines (e.g., automobiles) must be assigned the PG II entry 
regardless of variations in volatility.
    The entry ``Gasoline,'' UN1203, would be revised in Column (7) by 
adding Special provision ``177'' to indicate that gasoline for use in 
an internal combustion engine (e.g., automobiles) must be assigned the 
PG II entry regardless of variations in volatility.
    The proper shipping name for the entry ``Hydrogen in a metal 
hydride storage system,'' UN3468, would be revised in Column (2) to 
read ``Hydrogen in a metal hydride storage

[[Page 44814]]

system or Hydrogen in a metal hydride storage system contained in 
equipment or Hydrogen in a metal hydride storage system packed with 
equipment.'' This revision appears as a ``Remove/Add'' in this 
rulemaking.
    A new entry ``1-Hydroxybenzotriazole, anhydrous, dry or wetted with 
less than 20 percent water, by mass,'' UN0508, would be added.
    A new entry ``1-Hydroxybenzotriazole, anhydrous, wetted with not 
less than 20 percent water, by mass,'' UN3474, would be added.
    The entry ``Hypochlorite solutions,'' UN1791, would be revised by 
adding the PG III description and associated packaging provisions to 
Columns (5) and (8), respectively. The PG III information was 
inadvertently omitted in a final rule under Docket HM-215I (71 FR 
78596; December 29, 2006). This revision appears as a ``Remove/Add'' in 
this rulemaking.
    The entry ``Magnesium nitrate,'' UN1474, would be revised in Column 
(7) by adding a new Special provision ``332.'' Special provision 
``332'' specifies magnesium nitrate hexahydrate is not subject to the 
HMR. Testing conducted by independent laboratories on magnesium nitrate 
hexahydrate in accordance with Test O.1: Test for Oxidizing Solids of 
the UN Manual of Tests and Criteria indicated magnesium nitrate 
hexahydrate does not have a burning rate to meet the criteria as a 
Division 5.1 oxidizer.
    The hazardous materials description for the entry ``Nitric acid, 
other than red fuming, with not more than 70 percent nitric acid,'' 
UN2031, PG II would be revised in Column (2) to read ``Nitric acid, 
other than red fuming, with at least 65 percent, but not more than 70 
percent nitric acid'' to conform with proper shipping names that have 
similar descriptions (e.g., UN3366). This entry would also be revised 
in Column (7) by adding Special provision ``IP15,'' and in Column (10B) 
by removing vessel stowage codes ``44,'' ``110,'' and ``111,'' and 
adding ``74'' in their place. Special provision ``IP15'' specifies that 
for UN2031 with more than 55% nitric acid, the use of rigid plastic 
IBCs and composite IBCs with a rigid plastic inner receptacle would be 
authorized for two years from the date of manufacture of the IBC. 
Finally, the entry would be revised by adding a Division 5.1 subsidiary 
hazard label to column (6). This revision appears as a ``Remove/Add'' 
in this rulemaking.
    A new entry ``Nitric acid, other than red fuming, with less than 65 
percent nitric acid,'' UN2031, PG II would be added.
    The entry ``Nitrocellulose, solution, flammable with not more than 
12.6 percent nitrogen, by mass, and not more than 55 percent 
nitrocellulose,'' UN 2059, PG II and PG III, would be revised in Column 
(7) by adding a new Special provision ``198.'' Special provision 
``198'' authorizes nitrocellulose solutions containing less than 20% 
nitrocellulose to be transported as paint or printing ink.
    The entry ``Organometallic substance, liquid, water-reactive, 
flammable,'' UN3399, would be revised in Column (10A) by removing 
vessel stowage location code ``E'' and adding ``D'' to harmonize with 
the IMDG Code and SOLAS. Amendments were also made to SOLAS Chapter II-
2/Regulation 19 strictly prohibiting the stowage of 4.3 liquids having 
a flashpoint less than 23 [deg]C under deck or in enclosed roll-on/
roll-off (ro-ro) vessel spaces. SOLAS Chapter II-2/Regulation 19 sets 
out fire-fighting construction and equipment requirements for vessels 
carrying dangerous goods. We believe this proposed amendment is 
necessary to avoid the risk of a carrier stowing a package in an 
enclosed space that is not properly equipped for a Class 4.3 material 
with a subsidiary Class 3 and a flashpoint less than 23 [deg]C. When a 
flammable liquid with a flashpoint less than 23 [deg]C is stowed under 
deck, the space must be ventilated but cannot have electrical equipment 
in the space. In most cases, natural or mechanical ventilation is used. 
However, powered ventilation is required for Class 4.3 under deck due 
to the risk of moisture in the air and the entry of sea water into the 
hold through the ventilation openings. This proposed change would 
prohibit only UN3399 from under deck stowage. All other Class 4.3 
liquids, with a subsidiary Class 3 and flashpoint less than 23 [deg]C, 
are not permitted under deck or in enclosed ro-ro spaces under the IMDG 
Code.
    The proper shipping name for the entry ``Pentaerythrite 
tetranitrate mixture, desensitized, solid, n.o.s.,'' UN3344, would be 
revised in Column (2) to read ``Pentaerythrite tetranitrate mixture, 
desensitized, solid, n.o.s. or Pentaerythritol tetranitrate mixture, 
desensitized, solid, n.o.s. or PETN mixture, desensitized, solid, 
n.o.s.,'' to conform to proper shipping names that have similar 
descriptions (e.g., UN0411). This revision appears as a ``Remove/Add'' 
in this rulemaking.
    The entry ``Polychlorinated biphenyls, solid,'' UN3432 would be 
revised in Column (7) by adding Special provisions ``IP2'' and ``IP4'' 
for consistency with similar requirements for ``Polyhalogenated 
biphenyls, solid or Polyhalogenated terphenyls, solid,'' UN3152. 
Special provisions ``IP2'' and ``IP4'' require IBCs other than metal or 
rigid plastic to be offered for transportation in a closed freight 
container or closed transport vehicle and require flexible, fiberboard, 
or wooden IBCs to be sift-proof and water-resistant or be fitted with a 
sift-proof or water-resistant liner, respectively.
    The entries ``Potassium persulfate,'' UN1492 and ``Sodium 
persulfate,'' UN1505, would be revised in Column (10B) by removing 
vessel stowage code ``56'' and adding ``145.''
    The proper shipping name for the entry ``Trinitrophenol, wetted,'' 
UN1344, would be revised in Column (2) to read ``Trinitrophenol, or 
Picric acid, wetted,'' to conform to proper shipping names that have 
similar descriptions (e.g., UN3364). This revision appears as a 
``Remove/Add'' in this rulemaking.
    The proper shipping name for the entry ``Trinitrotoluene, wetted,'' 
UN1356, would be revised to read ``Trinitrotoluene, wetted or TNT, 
wetted,'' to conform to proper shipping names that have similar 
descriptions (e.g., UN3366). This revision appears as a ``Remove/Add'' 
in this rulemaking.
    A new entry ``Signals, distress, ship,'' UN0505, would be added.
    A new entry ``Signals, distress, ship,'' UN0506, would be added.
    A new entry ``Signals, smoke,'' UN0507, would be added.
    A new entry ``Powder, smokeless,'' UN0509, would be added. A 
discussion of changes to Sec.  173.62 provides an explanation of the 
addition of this new entry.
    Currently, no portable tank instructions are assigned to ``Water-
reactive liquid, corrosive, n.o.s.,'' UN3129; ``Water-reactive liquid, 
n.o.s.,'' UN3148; or to the PG I entries for ``Water reactive solid, 
corrosive, n.o.s.,'' UN3131; and ``Water-reactive solid, n.o.s.,'' 
UN2813. We would add portable tank assignments (portable tank special 
provisions) consistent with the ``Guidelines for Assigning Portable 
Tank Requirements to Substances in Classes 3 to 9.'' These assignments 
are consistent with similarly classed entries in the HMT. The entries 
would be revised in Column (7) as follows:
    The entry ``Water-reactive liquid, corrosive, n.o.s.,'' UN3129, PG 
I, would be revised by adding Special provisions ``T14,'' ``TP2,'' and 
``TP7.''
    The entry ``Water-reactive liquid, corrosive, n.o.s.,'' UN3129, PG 
II, would be revised by adding Special provisions ``T11'' and ``TP2.''

[[Page 44815]]

    The entry ``Water-reactive liquid, corrosive, n.o.s.,'' UN3129, PG 
III, would be revised by adding Special provisions ``T7'' and ``TP1.''
    The entry ``Water-reactive liquid, n.o.s.,'' UN3148, PG I, would be 
revised by adding Special provisions ``T9,'' ``TP2,'' and ``TP7.''
    The entry ``Water-reactive liquid, n.o.s.,'' UN3148, PG II, would 
be revised by adding Special provisions ``T7'' and ``TP2.''
    The entry ``Water-reactive liquid, n.o.s.,'' UN3148, PG III, would 
be revised by adding Special provisions ``T7'' and ``TP1.''
    The entry ``Water-reactive solid, corrosive, n.o.s,'' UN3131, PG I, 
would be revised by adding Special provisions ``T9'', ``TP7,'' and 
``TP33.''
    The entry ``Water-reactive solid, n.o.s.,'' UN2813, PG I, would be 
revised by adding Special provisions ``T9'', ``TP7,'' and ``TP33.''
    The proper shipping name for the entry ``Xenon,'' UN2036, would be 
revised to read ``Xenon, compressed,'' UN2036, for consistency with 
proper shipping names for other compressed gases (i.e., inert gases). 
This revision appears as a ``Remove/Add'' in this rulemaking.
Appendix B to Sec.  172.101
    Appendix B to Sec.  172.101 lists Marine Pollutants regulated under 
the HMR and prescribes requirements for classifying and describing a 
marine pollutant. In this NPRM, we are proposing to amend the 
introductory text and the List of Marine Pollutants to add an allowance 
for the use of the revised classification criteria for materials toxic 
to the aquatic environment (marine pollutants) contained in the IMDG 
Code. Additionally, under Docket HM-215D (66 FR 33316; June 21, 2001 
and 67 FR 15743; April 3, 2002), a number of entries were removed 
because they no longer met the criteria for a ``Marine Pollutant.'' 
However, some entries were inadvertently retained. Therefore, we are 
proposing to remove the following entries from the List of Marine 
Pollutants: ``5-Ethyl-2-picoline,'' ``Ethyl propenoate, inhibited'' 
``Isopropenylbenzene,'' and ``2-Phenylpropene.''
Section 172.102
    Section 172.102 lists a number of 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. For 
consistency with international regulations, we propose to amend Sec.  
172.102, Special provisions, as follows:
    Special provision ``36'' specifies maximum net quantity limits per 
package for the transport of medicines classified as flammable or toxic 
(i.e., UN1851, UN3248, and UN3249). These limits are inconsistent with 
the packaging limits authorized in limited quantity exceptions for 
these materials. The entries were initially introduced to the UN 
Recommendations with a special provision limiting the materials to PG 
II and III and requiring the materials to have a maximum net quantity 
per package of 5 L or 5 kg. However, since then, these materials have 
been authorized in the HMR as limited quantities and consumer 
commodities. This has created an inconsistency between the quantity 
limits per package in Special provision ``36'' and the limits outlined 
in the limited quantity exceptions. Therefore, to resolve this 
inconsistency, we would remove Special provision ``36.''
    Special provision ``137'' specifies conditions for exception from 
the HMR for certain types of vegetable fibers. We propose to revise the 
Special provision to include ``tampico fiber, dry'' having a minimum 
baling density of 360 kg/m\3\ as being eligible for this exception.
    Special provision ``138'' specifies insolubility criteria for lead 
compounds. We are proposing to revise the Special provision to add 
clarifying language that specifies lead compounds meeting the 
insolubility criteria outlined in the Special provision are not subject 
to the HMR unless they meet the criteria for one of the other hazard 
classes.
    Special provision ``150'' specifies composition limits for uniform 
mixtures of fertilizers containing ammonium nitrate as the main 
ingredient. We are proposing to revise the composition limits outlined 
in paragraph (b) of the provision by adding the words ``and/or mineral 
calcium sulphate'' after ``dolomite.''
    In the final rule under Docket HM-215G (69 FR 76044; December 20, 
2004), we added new generic entries to describe Organometallic 
materials consistent with descriptions added to the UN Recommendations, 
but allowed the continued use of several specific Organometallic 
entries (e.g., Dimethylzinc, UN1370). We anticipated removing these 
remaining entries from the HMT by January 1, 2007. The entries were to 
be removed because they were superseded by the addition of the more 
appropriate generic entries. However, they currently remain in the HMT. 
Therefore, we are proposing to remove the remaining specific 
Organometallic entries for consistency with the original intent of HM-
215G to remove the entries by January 1, 2007. In addition, we are 
proposing to remove Special provision ``173.'' Special provision 
``173'' provides the option to use an appropriate generic entry listed 
in the HMT to describe the material and was only assigned to 
Organometallic materials. Since new generic entries have been added to 
the HMT, and because the Special provision only applies to entries that 
are to be removed, this Special provision would be rendered obsolete.
    Special provision ``177'' requires materials for use in internal 
combustion engines (e.g., in automobiles) to be assigned the PG II 
entry regardless of variations in volatility of the material. The 
Special provision is currently assigned to the entry ``Ethanol and 
gasoline mixture or Ethanol and motor spirit mixture or Ethanol and 
petrol mixture,'' UN3475. However, the provision also applies to the 
entries ``Gasohol,'' NA1203 and ``Gasoline,'' UN1203. For consistency 
with UN Recommendations that assign similar provisions to gasoline and 
mixtures of ethanol and gasoline, and for uniform application of the 
provision, we are proposing to revise Special provision ``177'' to 
specify its application to both gasoline and ethanol/gasoline mixtures.
    Special provision ``188'' specifies conditions for exception from 
the HMR for small lithium cells and batteries. We propose to revise the 
Special provision to require the reporting of incidents, including 
those which result in the production of smoke, sparks, or a dangerous 
evolution of heat.
    Special provision ``189'' specifies conditions for exception from 
the HMR for medium lithium cells and batteries. We propose to revise 
the Special provision to require the reporting of incidents including 
those which result in the production of smoke, sparks, or a dangerous 
evolution of heat.
    A new Special provision ``198'' would be added to permit 
nitrocellulose solutions containing less than 20% nitrocellulose to be 
transported as paint or printing ink, as applicable.
    A new Special provision ``237'' would be added to specify that 
``Batteries, dry, containing potassium hydroxide solid, electric 
storage'' must be prepared and packaged in accordance with the 
requirements of Sec.  173.159(a), (b) and (c), and for transportation 
by aircraft, Sec.  173.159(d)(2).
    A new Special provision ``332'' would be added to specify magnesium 
nitrate hexahydrate is not subject to the HMR.
    A new Special provision ``335'' would be added to clarify proper 
classification of mixtures of solids which are not

[[Page 44816]]

subject to the HMR and environmentally hazardous liquids or solids. 
Special provision ``335'' specifies these mixtures would be classified 
as UN3077 and may be transported under that entry provided there is no 
free liquid visible at the time the material is loaded or the packaging 
or transport unit is closed.
    A new Special provision ``IP15'' would be added to indicate that 
for ``Nitric acid,'' UN2031, with more than 55% nitric acid, the use of 
rigid plastic IBCs and composite IBCs with a rigid plastic inner 
receptacle is permitted for two years from the date of manufacture of 
the IBC.
    A new Special provision ``N90'' would be added to prohibit the use 
of metal packagings for transport of ``1-Hydroxybenzotriazole, 
anhydrous, wetted not less than 20 percent water, by mass,'' UN3474.
    Special provision ``TP12'' would be removed. This provision states 
``this material is considered highly corrosive to steel.'' The phrase 
``highly corrosive to steel'' is not defined by any specific criteria. 
Further, ``TP12,'' unlike other TP codes, is simply a statement and 
does not apply any regulatory requirement. It is unclear if all highly 
corrosive materials are assigned Special provision ``TP12'' or if this 
statement provides any useful guidance for selecting an appropriate 
portable tank. Therefore, we propose to delete Special provision 
``TP12'' from Sec.  172.102(c)(8) ``TP'' Codes.
Section 172.202
    Section 172.202 establishes the requirements for the description of 
hazardous materials on shipping papers. The UN Recommendations do not 
require the subsidiary hazard to be indicated on the shipping paper 
when a subsidiary hazard label is not required. We agree that the 
requirement to indicate the subsidiary hazard on the shipping paper 
should be consistent with the requirement to apply a subsidiary risk 
label. Therefore, we propose to harmonize with the UN Recommendations 
by making an appropriate revision to Sec.  172.202(a)(2) to specify 
that the subsidiary hazard class or division number is not required to 
be entered when a corresponding subsidiary hazard label is not 
required. We also propose to revise paragraph (a)(4) to clarify that 
the packing group is not required to be indicated on a shipping paper 
for explosives, self-reactive substances, batteries other than those 
containing sodium, and organic peroxides in addition to entries that 
are not assigned a packing group. In addition, we also propose to 
revise paragraph (a)(6) to clarify that for all articles where ``No 
Limit'' is shown in Column (9A) or (9B) of the HMT, the quantity must 
be the gross mass, following the letter ``G.''
Section 172.322
    Section 172.322 specifies marking requirements for vessel 
transportation of each non-bulk packaging and bulk packaging that 
contains a marine pollutant. In this NPRM we are proposing to adopt the 
new marking for marine pollutants that has been incorporated into the 
IMDG Code. We are proposing mandatory use of this marking one year 
after publication of the final rule. Commenters are requested to submit 
remarks regarding the impact of adopting a one-year compliance date. As 
part of their petition to PHMSA (P-1516), DGAC recommended inclusion of 
the new marine pollutant mark in the HMR.
Section 172.400a
    Section 172.400a establishes exceptions for labeling requirements. 
Currently, the UN Recommendations do not require a package labeled with 
a Division 4.2 label to bear a Division 4.1 subsidiary hazard label. 
This is primarily because the Division 4.2 label communicates a more 
severe spontaneously combustible flammability hazard and as such the 
Division 4.1 label is not considered to provide additional hazard 
communication value. In this NPRM, we propose to revise paragraph (c) 
to include a similar exception.
Section 172.401
    Section 172.401 establishes specific requirements for prohibited 
labeling. We received a petition (P-1494) from the DGAC requesting that 
PHMSA specify that pictograms described in the United Nations Globally 
Harmonized System of Classification and Labelling are not prohibited 
under the HMR. In its petition, DGAC states that the UN Economic and 
Social Council's Committee of Experts on the Transport of Dangerous 
Goods and on the GHS established the goal of implementing the GHS in 
2008. DGAC contends that to facilitate international trade, it is 
important that packages bearing GHS pictograms are acceptable for 
transportation in the United States. DGAC also states that GHS 
pictograms may already appear on packages used in transportation and 
cites Annex 7 of the GHS showing examples of GHS pictograms appearing 
on drums. Pictograms prescribed by GHS are not identical to labels 
required under the UN Recommendations or the HMR; such pictograms 
typically consist of a red bordered diamond with a hazard symbol such 
as a ``flame'' or a ``skull and cross-bones.'' DGAC expects these GHS 
pictograms to be smaller in size than the transport labels required 
under the HMR and international regulations.
    We agree with DGAC that the GHS pictograms should be permitted on 
packages intended for transportation in the United States to facilitate 
international trade. We also believe that such a revision will not 
diminish the current level of safety affecting these materials. 
Therefore, in this NPRM, we are proposing to amend Sec.  172.401 which 
prohibits the transportation of packages bearing any mark or label that 
could be confused or conflict with a label required under the HMR, to 
specify that restrictions under this section do not apply to packages 
labeled in conformance with the GHS.
Section 172.446
    Section 172.446 specifies the requirements for Class 9 labels. 
Unlike the HMR, the international regulations do not have a solid 
horizontal line dividing the lower and upper half of the Class 9 label. 
The Class 9 label in Sec.  172.446 depicts a solid horizontal line. For 
consistency with international regulations and to provide relief to the 
regulated community, in this NPRM, we propose to revise paragraph (b) 
to allow a solid horizontal line as an option.
Section 172.448
    Section 172.448 establishes the specifications for the ``CARGO 
AIRCRAFT ONLY'' label. For consistency with international regulations, 
in this NPRM, we are proposing to replace the current label. The symbol 
of this label is not altered; however the text is revised to read, 
``Forbidden in Passenger Aircraft.'' In addition, we propose to 
authorize continued use of the current label until January 1, 2013.

Part 173

Section 173.4
    Section 173.4 establishes the requirements for exceptions to the 
HMR for small quantities of Class 3, Division 4.1, Division 4.2 (PG II 
and III), Division 4.3 (PG II and III), Division 5.1, Division 5.2, 
Division 6.1, Class 7, Class 8, and Class 9 materials. Recently, 
provisions for the transport of hazardous materials in excepted 
quantities were incorporated into the UN Regulations and the IMDG Code. 
These provisions are based largely on existing excepted quantity 
provisions provided by the ICAO TI. The provisions permit certain small 
quantities of hazardous materials

[[Page 44817]]

to be transported with minimal regulation, but ensure a high level of 
safety through stringent packaging and testing requirements.
    The excepted quantity provisions adopted within the UN Regulations 
and the small quantity provisions of the HMR are similar, but not 
identical. For example, differences include variations in the 
authorized hazard classes and packing groups; differences in the 
quantities authorized per package; and differences in marking, 
documentation and incident reporting requirements. We believe that 
aligning the existing small quantity provisions in the HMR with the 
excepted quantity provisions for air and vessel transportation will 
enhance harmonization and increase safety. Therefore, for consistency 
with the UN Recommendations and to increase safety and facilitate 
international transportation, in this NPRM, we are proposing to adopt a 
new excepted quantity provision for transportation by aircraft and 
vessel into a new Sec.  173.4a. We stress that we are not proposing to 
remove the existing small quantity provisions in 173.4, but rather 
proposing to limit the use of these provisions to domestic highway and 
rail transportation. We also propose to move the exception for small 
quantities--less than 1 gram for solids and less than 1 milliliter for 
liquids per inner packaging currently found in Sec.  173.4(e)--to a new 
Sec.  173.4b. This would align the requirements of the HMR with those 
of the ICAO TI and the IMDG Code for transport by air and vessel, while 
maintaining the existing small quantity exceptions for domestic highway 
and rail transport. We welcome comments regarding the potential for 
confusion and any cost impacts resulting from this change. Small 
quantity exceptions would be separated into the following three 
sections:
    (1) Section 173.4 for small quantities transported by domestic 
highway and rail only;
    (2) Section 173.4a for excepted quantities transported by aircraft 
and vessel; and
    (3) Section 173.4b for de minimis quantities of material (less than 
1 gram for solids and less than 1 milliliter for liquids per inner 
packaging) transported by all modes.
    In addition, we considered extending the allowance for small 
quantity exceptions to fuel cells. Fuel cells by design offer a high 
degree of integrity and often contain a relatively small amount of 
hazardous material. However, we wish to maintain the level of safety 
ensured by the rigorous testing and packaging required for fuel cell 
cartridges of various types required by the provisions proposed in 
Sec.  173.230. Therefore, in this NPRM, we propose to revise Sec.  
173.4(d) to specify that fuel cell cartridges are not eligible for the 
small quantity exceptions.
Sections 173.12 and 173.134
    Section 173.12 establishes exceptions for shipments of waste 
materials. Section 173.134 establishes definitions, classification 
criteria, and exceptions for Division 6.2 (infectious substances). On 
January 28, 2008, we published a final rule under Docket HM-218D (73 FR 
4699) that added a new paragraph (f) in Sec.  173.12 to specify that 
household waste, as defined in Sec.  171.8, is not subject to the HMR. 
In addition, we revised a household waste exception in Sec.  
173.134(b)(13)(i) to reference the household waste definition in Sec.  
171.8. Upon publication of the final rule, we received a comment 
expressing concern with the implementation of these amendments. The 
commenter, Regulatory Resources Inc., expressed concern that this 
amendment was too broad and would allow entities such as large hotels 
undergoing renovation to offer their waste, including hazardous 
materials, for transportation as non-regulated materials. This was not 
our intention. In an effort to reduce confusion, we are proposing to 
revise these two sections to specify that household waste is not 
subject to the HMR when transported in accordance with applicable 
state, local, or tribal requirements.
Section 173.24b
    Section 173.24b establishes additional general requirements for 
bulk packagings. In this NPRM, we are proposing to add a new paragraph 
to clarify that IBCs and Large Packagings that are not designated and 
tested for stacking may not be stacked during transportation. In 
addition, we are also proposing to clarify that IBCs and Large 
Packagings that are intended for stacking may not have more weight 
superimposed upon them than is marked on the packaging.
Section 173.62
    Section 173.62 establishes specific packaging requirements for 
explosives. We received a petition (P-1505) from the Sporting Arms & 
Ammunition Manufacturers' Institute (SAAMI) requesting that PHMSA 
include a new proper shipping name ``Powder, smokeless,'' UN0509, to 
the Sec.  172.101 HMT and to include the new entry among the explosives 
assigned Packaging Instruction 114(b) in Sec.  173.62. In its petition, 
SAAMI states that the UN Sub-Committee of Experts on the Transport of 
Dangerous Goods adopted a proposal by SAAMI to add the new entry to its 
Dangerous Goods List and a related change to the packing provisions in 
the UN Recommendations.
    Typically, we harmonize with the UN following the formal adoption 
of a proposal into the published version of the UN Recommendations. 
However, because of the limited scope of this amendment and because the 
new entry allows for a more accurate classification of smokeless 
powder, we are proposing to amend Sec.  173.62 to include a new entry 
UN0509 to the Explosives Table, which specifies the Packing Instruction 
assigned to each explosive, and to add a reference to the new entry in 
Packing Instruction 114(b). We also propose to include a ``D'' in 
column 1 of the table entry to indicate that the entry is appropriate 
for domestic use but may not be appropriate for international 
transportation. Following the adoption of the entry within the IMDG 
Code and the ICAO TI, this indication would no longer be necessary, and 
it is our intention to remove the ``D'' in a future rulemaking 
consistent with the adoption of the entry within the aforementioned 
international regulations.
    Additionally, consistent with our proposal to add new entry ``1-
Hydroxybenzotriazole, anhydrous, dry or wetted with less than 20% 
water, by mass,'' Division 1.3C, UN0508, to the HMT, we are adding this 
material under Packing Instruction ``114(b).'' We propose to revise 
this instruction to specify that, for UN0508, inner packagings are not 
required if drums are used as the outer packaging. We also propose to 
add a new sentence under Packing Instruction 114(b) to prohibit metal 
packagings for UN0508. In addition, we propose to clarify that inner 
packagings are not necessary if drums are used as the outer packaging 
for UN0160 and UN0161.
Section 173.115
    The HMR define a Division 2.2 material (non-flammable, nonpoisonous 
compressed gas--including compressed gas, liquefied gas, pressurized 
cryogenic gas, compressed gas in solution, asphyxiant gas and oxidizing 
gas) as any material or mixture that ``exerts in the packaging an 
absolute pressure of 280 kPa (40.6 psia) or greater at 20 [deg]C (68 
[deg]F), or is a cryogenic liquid, and does not meet the definition of 
Division 2.1 or 2.3.'' Recently, the definition of Division 2.2 gases 
in the UN Recommendations was amended to include all liquefied gases, 
irrespective of their pressure. This amendment was made on the basis 
that certain liquefied gases that pose no pressure hazard at

[[Page 44818]]

ambient pressures and temperatures may exhibit a pressure hazard under 
conditions normally encountered in transport, such as increased 
temperature. In addition, the pressure of a Division 2.2 gas was 
amended to be 302 kPa absolute (43.8 psi); a slight increase from the 
current threshold of 280 kPa absolute (40.6 psi). In order to enhance 
safety and to maintain global uniformity with respect to the 
classification of Division 2.2 gases, we are proposing to adopt these 
amendments. Additionally, in this NPRM, we are proposing to re-
designate current paragraph (k) as a new paragraph (l). The new 
paragraph (k) would read ``For Division 2.2 gases, the oxidizing 
ability shall be determined by tests or by calculation in accordance 
with ISO 10156:1996 and ISO 10156-2:2005 (IBR, see Sec.  171.7 of this 
subchapter.)'' This revision would require the use of specific test and 
calculation methods for a more accurate determination of the oxidizing 
ability of Division 2.2 gases. Additionally, we propose to revise Sec.  
171.7 to incorporate these ISO standards.
Section 173.137
    Section 173.137 establishes packing group criteria for corrosive 
(Class 8) materials. In this NPRM, we are proposing to add a note to 
clarify that an additional test on the second material is not required 
when the initial test on either steel or aluminum indicates the 
material is corrosive.
Sections 173.162, 173.164, 173.166, 173.186, 173.306, 173.307, 175.10
    The ICAO TI recently adopted new amendments to require additional 
information to be included on the ``air waybill'' for certain hazardous 
materials. Currently, a number of hazardous materials are excepted from 
the full regime of the hazard communication requirements that generally 
apply to the transport of hazardous materials in the ICAO TI when 
certain conditions are met to ensure an appropriate level of safety. An 
example is non-spillable batteries, which are excepted if certain 
conditions specified in Special provision A67 of the ICAO TI are met. 
Frequently, the ICAO TI contains more restrictive or additional 
requirements and conditions that apply for air transportation. The 
special provisions that address these requirements contain packaging 
provisions, prohibitions, and exceptions from requirements for 
particular quantities or forms of materials. Many shippers may not be 
familiar with the regulations and special requirements for the 
transportation of dangerous goods by air as some shippers may only 
occasionally ship dangerous goods by air. Frequently, these shippers 
will offer hazardous materials in the same manner received when the 
initial mode of transport may have been surface transport.
    Shipments of undeclared or improperly prepared hazardous materials, 
particularly in the air mode, pose a significant safety threat. 
Improper packing and handling of these shipments could result in a 
release or a failure to communicate the inherent hazard or risk of the 
materials to emergency responders and transportation workers. 
Improperly packaged batteries, electrical devices, and articles such as 
lighters which contain ignition devices can serve as a source of fire 
if damaged during handling and transport. The issue of undeclared 
dangerous goods has received significant attention in recent years. The 
actual number of undeclared hazardous materials shipments is not known 
but when reported is generally related to an incident or accident in 
air transport.
    In addition, operator and freight forwarder personnel, particularly 
those accepting general cargo (non-hazardous materials) are trained to 
be alert for undeclared or ``hidden'' hazardous materials. Consignments 
of packages marked with key words such as ``lithium batteries,'' 
``chemicals,'' and the like, or with certain markings and labels may be 
challenged by carriers or freight forwarders and acceptance delayed, 
while the shipper verifies that the goods are not regulated. Infrequent 
consignors and those that have not received appropriate training must 
still be aware of the applicable requirements. The air acceptance 
process is based on a system of checks and balances that ensures that 
hazardous materials are properly prepared in accordance with the ICAO 
TI and in full compliance with all applicable safety requirements. When 
hazardous materials are offered for transportation in compliance with 
all applicable requirements, the risk in transport is significantly 
reduced. To enable air carriers to ascertain that a shipment conforms 
to applicable requirements, in this NPRM, for transportation by 
aircraft, we are proposing a number of amendments consistent with 
recently adopted amendments in the ICAO TI. Specifically we are 
proposing to require the consignor to include on the ``air waybill'' an 
indication that a hazardous material or article has met the applicable 
conditions for transport. This indication will allow freight forwarders 
and operators to verify that the consignor is aware of, and has 
complied with, the applicable regulatory requirements. Additionally, it 
will reduce the likelihood of unnecessary carrier delays by improving 
communication.
Section 173.196
    Section 173.196 establishes packaging requirements for Category A 
infectious substances. In this NPRM, we are proposing to revise 
paragraphs (a)(1) and (a)(2) by replacing the word ``watertight'' with 
``leakproof.'' These proposed revisions are consistent with 
international regulations. No substantive changes to the packaging 
requirements are intended by this wording change.
Section 173.206
    In this rulemaking, we are proposing to add a new packaging section 
(Sec.  173.206) to the HMR to harmonize with new packaging requirements 
for water-reactive chlorosilanes adopted in the Fifteenth revised 
edition of the UN Recommendations. The enhanced packaging requirements 
more adequately address the water-reactive properties of these 
materials. We are also evaluating whether packaging for other water-
reactive materials should also be enhanced. Depending on the outcome of 
our evaluation, we may propose further amendments to the UN 
Recommendations and the HMR. In the meantime, the entries affected by 
the proposed addition of new packaging Sec.  173.206 are as follows:

UN1724 Allyltrichlorosilane, stabilized
UN1728 Amyltrichlorosilane
UN1747 Butyltrichlorosilane
UN1753 Chlorophenyltrichlorosilane
UN2986 Chlorosilanes, corrosive, flammable, n.o.s.
UN2987 Chlorosilanes, corrosive, n.o.s.
UN2985 Chlorosilanes, flammable, corrosive, n.o.s.
UN3362 Chlorosilanes, toxic, corrosive, flammable, n.o.s.
UN3361 Chlorosilanes, toxic, corrosive, n.o.s.
UN1762 Cyclohexenyltrichlorosilane
UN1763 Cyclohexyltrichlorosilane
UN2434 Dibenzyldichlorosilane
UN1766 Dichlorophenyltrichlorosilane

UN1196 Ethyltrichlorosilane
UN1781 Hexadecyltrichlorosilane
UN1784 Hexyltrichlorosilane
UN2437 Methylphenyldichlorosilane
UN1250 Methyltrichlorosilane
UN1799 Nonyltrichlorosilane
UN1800 Octadecyltrichlorosilane
UN1801 Octyltrichlorosilane
UN1804 Phenyltrichlorosilane
UN1816 Propyltrichlorosilane

[[Page 44819]]

UN1298 Trimethylchlorosilane
UN1305 Vinyltrichlorosilane, stabilized
Section 173.222
    Section 173.222 specifies the requirements for dangerous goods in 
machinery or apparatus. Paragraph (c) of this section specifies the 
total net quantity limits contained in one item of machinery or 
apparatus. Consistent with the ICAO TI, we are proposing to prohibit 
Division 2.2 gases with subsidiary risks and refrigerated liquefied 
gases for transportation by aircraft as dangerous goods in machinery or 
apparatus.
Section 173.225
    Section 173.225 specifies packaging requirements and other 
provisions for organic peroxides. When the Sec.  172.101 table 
specifies this section, the organic peroxide must be packaged and 
offered for transportation in accordance with the provisions of this 
section. Each packaging must also conform to the general requirements 
of Subpart B of Part 173 and to the applicable requirements of Part 178 
of the HMR. Specifically, organic peroxides that require temperature 
control are subject to Sec.  173.21(f). When an IBC or bulk packaging 
is authorized and meets the requirements of paragraph (f) or (h) of 
Sec.  173.225, respectively, lower control temperatures than those 
specified for non-bulk packaging may be required. An organic peroxide 
not identified in paragraph (c), (e), or (g) of Sec.  173.225 by 
technical name, or not assigned to a generic type in accordance with 
paragraph (b)(3) of this section, must conform to the requirements in 
paragraph (c) of Sec.  173.128.
    The Organic Peroxides Table specifies by technical name those 
organic peroxides that are authorized for transportation and not 
subject to the approval provisions of Sec.  173.128. An organic 
peroxide identified by technical name is authorized for transportation 
only if it conforms to all applicable provisions of the table. In this 
NPRM, we are proposing to amend the Organic Peroxides Tables by adding 
new entries, revising current entries, and adding new Notes ``29,'' 
``30,'' and ``31'' following the Organic Peroxides Table. New Note 
``29'' would indicate that specific entries are not subject to the 
requirements of this subchapter for Division 5.2. New Notes ``30'' and 
``31'' would indicate that for specific entries, organic peroxides with 
a boiling point greater than 130 [deg]C (266 [deg]F) or available 
oxygen less than or equal to 6.7% are acceptable. We are also proposing 
to add new entries to the Organic Peroxide IBC Table in paragraph (e) 
of this section.
    The following current entries in the Organic Peroxides Table would 
be amended:

UN3101 tert-Amyl peroxy-3,5,5-trimethylhexanoate
UN3117 Di-(2-ethylhexyl) peroxydicarbonate [as a stable dispersion 
in water]

    The following entries would be added to the Organic Peroxides 
Table:

UN3119 tert-Amyl peroxyneodecanoate
UN3119 tert-Amyl peroxypivalate
UN3106 tert-Butyl peroxy 3,5,5-trimethlyhexanoate
UN3115 Cumyl peroxyneodecanoate
Exempt Cyclohexanone peroxide(s)
UN3105 2,2-DI-(tert-amylperoxy)-butane
Exempt Dibenzoyl peroxide
UN3109 tert-Butyl peroxybenzoate
UN3103 1,1-DI-(tert-butylperoxy)-cyclohexane
UN3109 1,1-Di-(tert-Butylperoxy) cyclohexane
UN3105 1,1-DI-(tert-butylperoxy)-cyclohexane + tert-butylperoxy-2-
ethylhexanoate
Exempt Di-(2-tert-butylperoxyisopropyl) benzene(s)
UN3103 1,1-DI-(tert-butylperoxy)-3,3,5-trimethylcyclohexane
UN3118 DI-2,4-dichlorobenzoyl peroxide
Exempt Di-4-chlorobenzoyl peroxide
Exempt Dicumyl peroxide
UN3119 Di-(2-ethylhexyl) peroxydicarbonate [as a stable dispersion 
in water]
UN3119 Di-(2-neodecanoyl-peroxyisopropyl) benzene, as stable 
dispersion in water
UN3115 3-Hydroxy-1,1-dimethylbutyl peroxyneodecanoate
UN3117 3-Hydroxy-1,1-dimethylbutyl peroxyneodecanoate
UN3119 3-Hydroxy-1,1-dimethylbutyl peroxyneodecanoate [as a stable 
dispersion in water]
UN3109 Methyl isopropyl ketone peroxide(s)
UN3107 3,3,5,7,7-Pentamethyl-1,2,4-trioxepane

    A new Note ``30'' would be added following the Organic Peroxides 
Table to read:
    ``Diluent type B with boiling point > 130 [deg]C (266 [deg]F).''
    A new ``Note ``31'' would be added following the Organic Peroxides 
Table to read:
    ``Active oxygen <= 6.7%.''
    The following entries would be revised or added to the Organic 
Peroxide IBC Table as follows:

UN3109 tert-Butyl peroxybenzoate, not more than 32% in diluent type 
A
UN3109 1,1-Di-(tert-Butylperoxy) cyclohexane, not more than 37% in 
diluent type A
UN3119 tert-Anyl peroxypivalate, not more than 32% in diluent type A
UN3119 tert-Butyl peroxyneodecanoate, not more than 52%, stable 
dispersion, in water
UN3119 Di-(2-neodecanoylperoxyisopropyl) benzene, not more than 42%, 
stable dispersion, in water
UN3119 3-Hydroxy-1,1-dimethylbutyl peroxy-neodecanoate, not more 
than 52%, stable dispersion, in water

    In addition, in the Organic Peroxide Portable Tank Table, UN3119 
``Di-(3,5,5-trimethyl-hexanoyl) peroxide, not more than 38% in diluent 
type A'' would be revised, and UN3119 ``tert-Amyl peroxyneodecanoate, 
not more than 47% in diluent type A'' would be added as a new entry.
Section 173.226
    Section 173.226 establishes non-bulk packaging requirements for 
Division 6.1 PG I, Hazard Zone A materials. In this NPRM, we are 
proposing to editorially revise paragraph (c) to enhance accuracy, 
reduce misunderstanding, and provide a more user-friendly format.
Section 173.230
    Section 173.230 establishes provisions for the transportation of 
fuel cell cartridges containing flammable liquids. As portable 
electronic devices continue to evolve, developers of fuel cell 
technologies are considering various types of fuel sources to meet 
increasing power demands. In addition to the flammable liquid fuel cell 
cartridges currently addressed in the HMR, fuel cell technologies may 
employ a range of fuels, including hydrogen in a metal hydride, butane, 
borohydrides and formic acid. The fuels may be a gas such as hydrogen 
in a metal hydride or butane that meets the defining criteria for a 
Division 2.1 material; a solid borohydride (including formulations) 
that meets the defining criteria for a Division 4.3 material; or liquid 
or solid formulations that meet the defining criteria as a Class 8 
material (e.g., sodium borohydride, or formic acid).
    Provisions addressing these fuel cell technologies have already 
been adopted in the Fifteenth revised edition of the UN 
Recommendations, the ICAO TI and the IMDG Code. Additionally, we have 
received petitions from HMT Associates, L.L.C. (P-1517) and the U.S. 
Fuel Cell Council (P-1518) requesting that we align the HMR provisions 
for fuel cell systems and cartridges with international standards. 
Consistent with DOT's strategic goals of ensuring safety while 
utilizing 21st century technology, we are proposing to add four new 
proper shipping names to the HMT to describe the range of fuel used in 
fuel cell cartridges: ``Water-reactive substances,'' UN3476; 
``Corrosive substances,'' UN3477; ``Liquefied flammable gas,'' UN3478; 
and ``Hydrogen in metal hydride,'' UN3479.

[[Page 44820]]

This proposal will provide guidance for the safe transportation of fuel 
cells and will introduce a greater variety of technology into the 
global market place. The type of hazard would not be included in the 
proper shipping name but, instead, would be identified by the hazard 
class or division (e.g., 2.1; 3; etc.). Readers should note that 
liquefied flammable gases and hydrogen in a metal hydride are both 
Division 2.1 materials used in fuel cell cartridges. However, the 
provisions necessary for the safe transportation of these articles are 
quite different and therefore, it is necessary to distinguish them with 
separate shipping descriptions. In addition, because fuel cell 
cartridges may contain any number of hazardous materials, we also 
propose to revise Sec.  173.230 to provide a comprehensive system to 
address the requirements for fuel cell cartridges containing various 
hazardous materials. Paragraph (a) of this section would outline 
requirements applicable to fuel cell cartridges containing any 
authorized fuel, while paragraphs (b), (c), and (d) would outline 
additional requirements unique to each fuel cell type. Further, 
paragraph (e) would provide a list of authorized packages and 
configurations, with paragraph (f) describing the additional 
requirements for the transportation of fuel cell cartridges by 
aircraft, including transport by passengers and crewmembers. Finally, 
paragraphs (g) and (h) would outline the limited quantity and consumer 
commodity provisions, respectively.
    In addition, for consistency with the ICAO TI in regard to the 
transportation of fuel cell cartridges, in Sec.  175.10, we propose to 
expand the types of fuel cell cartridges permitted in carry-on baggage 
by airline passengers and crew to include water-reactive substances and 
hydrogen in a metal hydride. Fuel cells permitted for transport by 
passengers and crew must continue to conform to certain rigorous 
performance criteria outlined in Sec.  175.10.
Section 173.304(b)
    Section 173.304(b) specifies additional requirements for liquefied 
compressed gases in UN pressure receptacles. In a final rule published 
on June 12, 2006, under Docket PHMSA-2005-17463 (HM-220E) entitled ``UN 
Cylinders,'' (71 FR 33858), we adopted the filling limits for liquefied 
compressed gases and mixtures in UN pressure receptacles specified in 
the UN Recommendations. Based on a review of the P200 filling limits, 
we lowered the filling limits for ten gases and added a table under 
paragraph (c) in Sec.  173.304b to specify the revised filling limits. 
The UN Recommendations subsequently adopted these revised filling 
limits. Since there is no longer a need for the revised filling limits 
for liquefied compressed gases in the HMR, in this NPRM, we propose to 
remove paragraph (c) of Sec.  173.304b in its entirety. Current 
paragraphs (d) and (e) would be re-designated accordingly.
Section 173.306
    Section 173.306 establishes transportation requirements for limited 
quantities of compressed gases. The ICAO TI have incorporated 
provisions for the transportation of limited quantities of compressed 
gases in plastic aerosols to keep abreast with new technology and on 
the basis that plastic aerosols provide a level of safety equivalent to 
other authorized packagings. Although the HMR do not currently allow 
the transportation of these plastic aerosols by air, PHMSA has issued 
several Special Permits authorizing such transportation with certain 
restrictions, such as shipping paper, labeling, marking, and packaging 
requirements. We have reviewed these materials from a risk/safety 
perspective, and based on an equivalent level of safety determination 
established by the Special Permits, and a record of the safe 
transportation of plastic aerosols, we are proposing to adopt 
requirements for the construction and use of plastic aerosols within 
the HMR. We believe this proposed amendment will also enhance 
international harmonization and provide relief to the regulated 
community by reducing the need for Special Permits to transport these 
materials. A new aerosol specification ``2S'' is proposed for inclusion 
in Sec.  173.306, with corresponding requirements as detailed in a new 
Sec.  178.33b.
    We are also proposing to revise paragraph (j) to require the 
consignor to include on an air waybill or other shipping documentation 
an indication that a hazardous material or article has met the 
applicable conditions for air transport. This indication will allow 
freight forwarders and operators to verify that the consignor is aware 
of, and has complied with, the applicable regulatory requirements.
Section 173.307
    Section 173.307 specifies exceptions for compressed gases. The ICAO 
TI have Special provision (A69) excepting from regulation articles 
containing minimal amounts of gallium, mercury, or inert gas. Based on 
a review that indicated the special provision was not assigned 
appropriately among all inert gases, ICAO proposed to assign the 
special provision to all the inert gases concerned. The HMR do not 
currently have a similar provision for inert gases, although the HMR 
have the same exception for articles containing gallium or mercury in 
Sec. Sec.  173.162 and 173.164, respectively. Rather than adding a new 
special provision, we are proposing to add to this section a general 
exception for articles containing inert gas. This exception would 
specify that manufactured articles or apparatuses, each containing not 
more than 100 mg of inert gas and packaged so that the quantity of 
inert gas per package does not exceed 1 g, are not subject to the HMR.
Section 173.322
    Section 173.322 establishes specific packaging requirements for 
ethyl chloride (UN1037). Recently, PHMSA became aware of an incident 
involving an aluminum compressed gas cylinder containing ethyl 
chloride. The investigation of this incident suggests the possibility 
that a reaction occurred within the aluminum cylinder as a result of 
the incompatibility between the ethyl chloride gas and the aluminum 
cylinder. The HMR currently prohibit the transportation of ethyl 
chloride in UN pressure receptacles constructed of aluminum alloy but 
have no such prohibition for specification cylinders. To address this 
occurrence, in this NPRM, we are proposing to prohibit the filling of 
specification cylinders made of aluminum alloy (e.g., DOT 3AL) with 
ethyl chloride.

Part 175

Section 175.10
    Section 175.10 establishes exceptions for the transportation of 
certain hazardous materials by aircraft, including hazardous materials 
that may be carried by passengers, crewmembers, and air operators in 
checked or carry-on baggage. In this NPRM, we are proposing to revise 
the exception for dry ice in paragraph (a)(10) to clarify that dry ice 
carried in both carry-on and checked baggage is subject to the approval 
of the aircraft operator.
    As noted under the discussion in Sec.  173.230, we are also 
proposing to revise paragraph (a)(18) to expand the types of fuel cell 
cartridges permitted in carry-on baggage by airline passengers and 
crew. Fuel cells permitted for transport by passengers and crewmembers 
must continue to conform to the rigorous performance criteria outlined 
in Sec.  175.10.
    In addition, we are proposing to revise paragraph (a) and add a new 
paragraph (c) to specify that the

[[Page 44821]]

requirements to submit incident reports under Sec. Sec.  171.15 and 
171.16 of this subchapter apply to the air carrier.
Section 175.33
    Section 175.33 establishes requirements for shipping papers and 
notification of pilot-in-command for hazardous materials transported by 
aircraft. We are proposing several amendments to strengthen and clarify 
these requirements, harmonize with international standards, and address 
a recommendation of the National Transportation Safety Board (NTSB) 
arising out of a 2006 incident.
    On February 7, 2006, United Parcel Service Company (UPS) flight 
1307, landed at its destination, Philadelphia International Airport, 
after a cargo smoke indication in the cockpit. The flight crewmembers 
evacuated the airplane upon landing and sustained minor injuries. The 
aircraft and most of the cargo, however, were destroyed. In its 
investigation of the incident, the NTSB determined that UPS personnel 
were able to retrieve the notice to captain (NOTOC), which contained 
information on the hazardous materials on board the airplane. However, 
NTSB also determined that personnel did not provide emergency 
responders with detailed information about the hazardous materials on 
board the airplane in a timely manner, and such a delay could have 
potentially created a safety hazard. As a result of its findings, NTSB 
recommended that PHMSA ``require aircraft operators that transport 
hazardous materials to immediately provide consolidated and specific 
information about hazardous materials on board an aircraft, including 
proper shipping name, hazard class, quantity, number of packages, and 
location to on-scene emergency responders upon notification of an 
accident or incident.'' (NTSB Recommendation A-07-106)
    The HMR currently require aircraft operators to make available, 
upon request, to an authorized official of a Federal, State, or local 
government agency, including an emergency responder, at reasonable 
times and locations, the documents or information required by Sec.  
175.33, which include shipping papers and notification of pilot-in-
command. However, aircraft operators are not required to provide 
hazardous materials information to emergency responders immediately 
upon notification of an accident or incident. We agree with NTSB that 
delays in the transmittal of information to emergency responders could 
delay timely and effective response to incidents. Under the Docket HM-
206C NPRM published on March 25, 2003 (68 FR 14341), we stated that the 
``information'' must be provided to an emergency responder with no 
undue delay.'' Therefore, in this NPRM, we are proposing to revise 
paragraph (c)(4) of this section to require aircraft operators that 
transport hazardous materials to provide immediate and specific 
information about hazardous materials on board an aircraft, including 
proper shipping name, hazard class, quantity, number of packages, and 
location, to on-scene emergency responders in the event of an accident 
or incident.
    In addition, for consistency with international regulations, in 
this NPRM, we are proposing to add a new paragraph (a)(11) to specify 
that for ``Carbon dioxide, solid (dry ice),'' UN1845, only the UN 
number, proper shipping name, class, total quantity, exact location 
aboard the aircraft, and the airport at which the package(s) is to be 
unloaded need be provided.
    In response to a FedEx Express petition, [P-1490], we are also 
proposing to revise Sec.  175.33(a)(1)(i) to remove the requirement 
that the type of package must be included on the notification of pilot-
in-command.
Section 175.75
    Section 175.75 specifies the requirements for quantity limitations 
and cargo locations for hazardous materials transported by aircraft. 
Paragraph (d) requires that each package containing a hazardous 
material acceptable only for cargo aircraft must be loaded in such a 
manner that a crew member or other authorized person can access, handle 
and when size and weight permit, separate such packages from other 
cargo during flight. To increase flexibility in these stowage 
requirements, we believe we can expand this requirement to allow for 
the stowage of these materials in inaccessible cargo compartments 
without decreasing the current level of safety, provided the 
compartment has an FAA-approved fire or smoke detection system and a 
fire-suppression system. Therefore, in this NPRM, we are proposing to 
revise paragraph (d) to provide an alternative that a package 
containing a hazardous material acceptable only for cargo aircraft may 
be loaded in an inaccessible cargo compartment provided the compartment 
has an FAA-approved fire or smoke detection system and a fire-
suppression system. Accordingly, we would also revise paragraph (d) to 
provide for a more user-friendly format.
Section 175.88
    Section 175.88 specifies the requirements for the inspection, 
orientation and securing of packages of hazardous materials transported 
by aircraft. We are proposing to revise paragraph (c) to specify that 
packages of hazardous materials must be secured at all times in an 
aircraft in a manner that will prevent shifting or prevent a change in 
the position of the packages in the cargo compartment.

Part 176

Section 176.2
    Section 176.2 establishes definitions specific to the 
transportation of hazardous materials by vessel. In this NPRM, we are 
proposing to editorially revise the definition for ``Commandant'' to 
update a routing designation.
Section 176.3
    Section 176.3 establishes requirements for shipments of hazardous 
materials that are unacceptable for transportation by vessel, and 
requires compliance with parts 172 and 173 of the HMR. In this NPRM, we 
are proposing to specify that compliance with part 171 is also 
required.
Section 176.84
    Section 176.84 establishes requirements for stowage and segregation 
for cargo vessels and passenger vessels. Consistent with proposed 
revisions for certain materials in the HMT, we are proposing to remove 
stowage codes ``134,'' ``139,'' and ``140,'' and add a new stowage code 
``145.'' Stowage code 140 is assigned to ``Aluminum alkyl halides, 
liquid,'' UN3052, and ``Aluminum alkyl halides, solid,'' UN3461. Both 
of these shipping descriptions are proposed to be removed consistent 
with the adoption of appropriate generic organometallic entries. 
Stowage code ``139'' provides instruction to ``stow `separated from' 
mercury salts.'' The provision is a duplicate of stowage code ``70,'' 
and both codes are assigned to the entry ``1,4-Butynediol,'' UN2716. 
Additionally, stowage code ``139'' is only assigned to this specific 
entry. Therefore, we are proposing to remove stowage code ``139.'' 
Stowage code ``140'' provides instruction to ``stow `separated from' 
UN3052 and UN3461,'' which are identification numbers for aluminum 
alkyl halides in liquid and solid form, respectively. These entries are 
proposed to be removed in this rule. Consistent with the removal of 
these UN numbers from the hazardous materials table we are proposing to 
remove stowage code ``140.'' Stowage code ``145'' provides instruction 
to ``stow `separated from' ammonium compounds

[[Page 44822]]

except for UN1444.'' The stowage code is assigned to ``Potassium 
persulfate,'' UN1492, and ``Sodium persulfate,'' UN1505. These 
materials may form explosive mixtures with ammonium compounds; however, 
they do not react dangerously or form explosive mixtures when in 
contact with ``Ammonium persulphate,'' UN1444. Finally, in order to 
fully align the HMR with the IMDG Code, a new vessel stowage code 
``146'' is added to specify that, ``Category B stowage applies for unit 
loads in open cargo transport units.'' The new vessel stowage code 
``146'' is assigned to ``Batteries, wet, filled with acid, electric 
storage,'' UN2794 and ``Batteries, wet, filled with alkali, electric 
storage,'' UN2795 in column (10B) of the HMT.
Section 176.172
    Section 176.172 establishes the structural serviceability 
requirements for freight containers and vehicles carrying Class 1 
(explosive) materials on vessels. The IMDG Code, as recently amended, 
establishes similar requirements; however, unlike the HMR, the IMDG 
requirements expressly except containers carrying Division 1.4 
explosives. Under the HMR, as provided in Sec.  176.172(c), Division 
1.4 explosive materials need not be accompanied by a statement 
certifying that the freight container is structurally serviceable. 
However, this certification exception does not explicitly except 
freight containers carrying Division 1.4 explosives from the underlying 
serviceability requirements. Because Division 1.4 explosives pose a 
minimal explosive risk, the structural serviceability requirements, 
like an accompanying certification, become correspondingly less 
valuable as a safety control. Therefore, in this rulemaking, we propose 
to amend paragraph (a) of this section to be consistent with the 
requirements of the IMDG Code, by excluding freight containers 
containing Division 1.4 explosive materials from the serviceability 
requirements.

Part 178

Section 178.33b
    As noted in the discussion under Sec.  173.306, we are proposing to 
add a new section that defines the design, construction, and testing 
requirements for plastic aerosols. Specifically, we are proposing to 
add a new Sec.  178.33b to specify packaging; compliance; type and 
size; inspection; duties of an inspector; material; manufacture; design 
qualification, production, and leak testing; and marking requirements 
for plastic aerosols.
Section 178.502
    Section 178.502 establishes the identification codes for marking 
packagings to certify conformance with UN performance standards. We 
propose to include a note at the end of this section to indicate that 
plastic materials include other polymeric materials such as rubber and, 
thus, the code used to designate plastic packagings may also be used 
for packagings constructed of other polymeric materials.
Section 178.703
    Section 178.703 establishes marking requirements for IBCs. We 
propose to include an additional marking requirement to specify the 
maximum permitted stacking load applicable when an IBC is in use, with 
a transition date until January 1, 2011. The symbol must be not less 
than 100 mm (3.9 inches) x 100 mm (3.9 inches), and must be durable and 
clearly visible. The letters and numbers must be at least 12 mm high 
(.48 inches). The mass marked above the symbol must not exceed the load 
imposed during the design test divided by 1.8.
Section 178.801
    Section 178.801 establishes general requirements for the testing of 
IBCs. For clarification, in this NPRM, we propose to add a sentence to 
paragraph (f) to specify that the IBC must be fitted with the primary 
bottom closure during production testing and inspection.
Section 178.810
    Section 178.810 establishes the requirements for a drop test 
conducted for the qualification of all IBC design types. In this NPRM, 
we propose to revise the criteria in paragraph (e) for passing the drop 
test to specify that no damage is permitted which renders the IBC 
unsafe to be transported for salvage or for disposal, or results in a 
loss of contents. In addition, we are revising this paragraph to 
specify that the IBC must be capable of being lifted by an appropriate 
means until clear of the floor for five minutes.

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, as discussed 
in detail above, the proposed rule amends the HMR to more fully align 
them with the biennial updates of the UN Recommendations, the IMDG Code 
and the ICAO TI; this will facilitate the transport of hazardous 
materials in international commerce.
    Harmonization serves to facilitate international transportation; 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 public. 
Thus, as explained in the corresponding sections above, we are not 
proposing harmonization with certain specific provisions of the UN 
Recommendations, 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.
    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, the rule proposes to incorporate changes into the HMR 
based on the Fifteenth revised edition of the UN Recommendations, 
Amendment 34 to the IMDG Code, and the 2009-2010 ICAO TI, which become 
effective January 1, 2009. The continually increasing amount of 
hazardous materials transported in international commerce warrants the 
harmonization of domestic and international

[[Page 44823]]

requirements to the greatest extent possible.

B. Executive Order 12866 and DOT Regulatory Policies and Procedures

    This proposed rule is not considered a significant regulatory 
action under section 3(f) of Executive Order 12866 and, therefore, was 
not reviewed by the Office of Management and Budget. The proposed rule 
is not considered a significant rule under the Regulatory Policies and 
Procedures of the Department of Transportation [44 FR 11034]. This 
proposed rule applies to offerors and carriers of hazardous materials, 
such as chemical manufacturers, chemical users and suppliers, packaging 
manufacturers, distributors, battery manufacturers, radiopharmaceutical 
companies, and training companies. Benefits resulting from the adoption 
of the amendments in this proposed rule include enhanced transportation 
safety resulting from the consistency of domestic and international 
hazard communications and continued access to foreign markets by U.S. 
manufacturers of hazardous materials.
    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.
    We propose a one-year transition period to allow for training of 
employees and to ease any burden on entities affected by the 
amendments. The total net increase in costs to businesses in 
implementing the proposed rule is considered to be minimal. Initial 
start-up and inventory costs would result from these changes; however, 
the costs would be offset by greater long-term savings of conformance 
with one set of regulations and a one-year transition period. A 
regulatory evaluation is available for review in the public docket for 
this rulemaking.

C. Executive Order 13132

    This proposed rule has been analyzed in accordance with the 
principles and criteria contained in Executive Order 13132 
(``Federalism''). This proposed rule preempts State, local and Indian 
tribe requirements but does not propose any regulation that has 
substantial direct effects on the States, the relationship between the 
national government and the States, or the distribution of power and 
responsibilities among the various levels of government. Therefore, the 
consultation and funding requirements of Executive Order 13132 do not 
apply.
    The Federal hazardous material transportation law, 49 U.S.C. 5101-
5128, contains an express preemption provision (49 U.S.C. 5125(b)) that 
preempts State, local, and Indian tribe requirements on certain covered 
subjects, as follows:
    (1) The designation, description, and classification of hazardous 
material;
    (2) The packing, repacking, handling, labeling, marking, and 
placarding of hazardous material;
    (3) The preparation, execution, and use of shipping documents 
related to hazardous material and requirements related to the number, 
contents, and placement of those documents;
    (4) The written notification, recording, and reporting of the 
unintentional release in transportation of hazardous material; and
    (5) The design, manufacture, fabrication, inspection, marking, 
maintenance, recondition, repair, or testing of a packaging or 
container represented, marked, certified, or sold as qualified for use 
in transporting hazardous material in commerce.
    This proposed rule addresses covered subject items (1), (2), (3), 
(4) and (5) above and preempts State, local, and Indian tribe 
requirements not meeting the ``substantively the same'' standard. This 
proposed rule is necessary to incorporate changes adopted in 
international standards, effective January 1, 2009. 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 section 5125(b)(2) that, if 
DOT issues a regulation concerning any of the covered subjects, DOT 
must determine and publish in the Federal Register the effective date 
of Federal preemption. The effective date may not be earlier than the 
90th day following the date of issuance of the final rule and not later 
than two years after the date of issuance. PHMSA proposes the effective 
date of Federal preemption be 90 days from publication of a final rule 
in this matter.

D. Executive Order 13175

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

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

    The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires an 
agency to review regulations to assess their impact on small entities, 
unless the agency determines that a rule is not expected to have a 
significant impact on a substantial number of small entities. This 
proposed rule facilitates the transportation of hazardous materials in 
international commerce by providing consistency with international 
standards. This proposed rule applies to offerors and carriers of 
hazardous materials, some of whom are small entities, such as chemical 
users and suppliers, packaging manufacturers, distributors, battery 
manufacturers, 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 final rule will 
relieve U.S. companies, including small entities competing in foreign 
markets, from the burden of complying with a dual system of 
regulations. Therefore, I 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

    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 collection and 
recordkeeping requests. There are no new information collection 
requirements in this notice of proposed rulemaking.

[[Page 44824]]

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 
$132 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 Counsel on Environmental Quality (CEQ) regulations 
order 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).
1. Purpose and Need
    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 the Hazardous Materials 
Regulations with recent changes to the International Maritime Dangerous 
Goods Code, the International Civil Aviation Organization's Technical 
Instructions for the Transport of Dangerous Goods by Air, and the 
United Nations Recommendations on the Transport of Dangerous Goods. The 
amendments are intended to enhance the safety 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 effective emergency response in the event of a 
hazardous materials incident.
    The HMR regulate materials that meet the definition of a marine 
pollutant in all modes of transportation. The intended effect is to 
increase the level of safety associated with the transportation of 
substances hazardous to the marine environment by way of improved 
communication of their presence in transportation and establishing 
appropriate requirements for their packaging. The HMR uses a list based 
system designed to help shippers determine if a material meets the 
definition of a marine pollutant. Recently, the IMO adopted a criteria 
based system for identification of materials hazardous to the marine 
environment based on the Globally Harmonized System of Classification 
and Labelling of Chemicals (GHS).
2. Alternatives
    In developing this proposed rule, we considered three alternatives:
    (1) Do nothing.
    (2) Adopt the international standards in their entirety.
    (3) Adopt most of the international standards, with certain 
modifications based on safety or economic considerations.
    Alternative 1:
    Because our goal is to facilitate uniformity, compliance, commerce 
and safety in the transportation of hazardous materials, we rejected 
this alternative.
    Alternative 2:
    Under this alternative, we would adopt the classification criteria 
for marine pollutants in the IMDG Code consistent with the aquatic 
toxicity criteria adopted within the GHS. However, the new 
classification system adopted into the IMDG Code is complicated and the 
associated criteria for classifying mixtures containing marine 
pollutants would involve an additional layer of complexity without a 
corresponding public benefit. Therefore, we are not proposing to 
require the use of the new IMDG Code environmental classification 
system.
    Alternative 3:
    Consistency between U.S. and international regulations helps to 
assure the safety 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 effective 
emergency response in the event of a hazardous materials incident. 
Under Alternative 3, we would harmonize the HMR with international 
standards to the extent consistent with U.S. safety and economic goals. 
As indicated above, we would not adopt provisions that, in our view, do 
not provide an adequate safety level. Further, we would provide for 
exceptions and extended compliance periods to minimize the potential 
economic impact of any revisions on the regulated community.
    Under this alternative, we would maintain the current marine 
pollutant criteria and list while permitting the use of the GHS 
Criteria. If a material not listed as a marine pollutant in the HMR 
meets the definition of a marine pollutant in accordance with the GHS, 
that material may be transported as a marine pollutant in accordance 
with the applicable regulations. Alternative 3 is the only alternative 
that addresses, in all respects, the purpose of this regulatory action, 
which is to facilitate the safe and efficient transportation of 
hazardous materials in international commerce. These actions will 
provide the greatest possible harmonization with international 
requirements without posing an undue increased cost burden on industry. 
For these reasons, alternative 3 is our recommended alternative.
3. Analysis of Environmental Impacts
    Hazardous materials are transported by aircraft, vessel, rail, and 
highway. The potential for environmental damage or contamination exists 
when packages of hazardous materials are involved in accidents or en 
route incidents resulting from cargo shifts, valve failures, package 
failures, or loading, unloading, or handling problems. The ecosystems 
that could be affected by a release include air, water, soil, and 
ecological resources (for example, wildlife habitats). The adverse 
environmental impacts associated with releases of most hazardous 
materials are short-term impacts that can be greatly reduced or 
eliminated through prompt clean-up of the accident scene. Most 
hazardous materials are not transported in quantities sufficient to 
cause significant, long-term environmental damage if they are released.
    The hazardous material regulatory system is a risk-management 
system that is prevention-oriented and focused on identifying hazards 
and reducing the probability and quantity of a hazardous material 
release. Amending the Hazardous Materials Regulations to maintain 
alignment with international standards enhances the safe transportation 
of hazardous materials in domestic and international commerce. When 
considering the adoption of

[[Page 44825]]

international standards under the HMR, we review and consider each 
amendment on its own merit and assess their impact on transportation 
safety and the environment.
    Alternative 1 would maintain the current marine pollutant 
classification system without change. We do not believe this would 
result in any significant impacts on the environment. Alternative 2 may 
result in a significant environmental impact if a material listed in 
the current marine pollutant list does not meet the GHS criteria. The 
recommended alternative 3 maintains the marine pollutant criteria and 
allows the voluntary use of the GHS criteria adopted by the IMDG Code. 
When a material meets the criteria under the GHS criteria but not the 
HMR, the material may still be transported under the applicable 
requirements for a marine pollutant. This would communicate the 
presence of an environmentally hazardous material consistent with the 
IMDG Code. Conversely, if a listed marine pollutant does not meet the 
GHS criteria, the material must be transported as a marine pollutant 
under the HMR unless approved by the Associate Administrator. The 
recommended alternative 3 would not result in any significant impact on 
the environment.
4. Consultations and Public Comment
    On June 22, 2005, November 16, 2005, June 21, 2006, and November 
29, 2006, PHMSA hosted public meetings with public and private 
stakeholders to discuss draft U.S. positions on the United Nations' 
Sub-Committee of Experts on the Transport of Dangerous Goods (UNSCOE) 
proposals for the Fifteenth revised edition of the UN Recommendations 
on the Transport of Dangerous Goods Model Regulations. In addition, 
PHMSA and the U.S. Coast Guard hosted a public meeting on August 29, 
2006, and hosted a second meeting on September 6, 2007, to discuss 
amendments to the IMDG Code. A public meeting was held in October 2007 
to discuss amendments to the ICAO TI. During these public meetings, 
U.S. positions on proposed amendments to the UN Recommendations were 
considered and discussed. Positions were established based on input 
received during these meetings in conjunction with internal review, 
including thorough technical review.
    We have identified a number of immediate and long-term actions that 
participants in the international community are taking or will take to 
enhance the safe transportation of hazardous materials. Through this 
integrated and cooperative approach, we believe we can be most 
successful in reducing incidents, enhancing safety, and protecting the 
public. We expect to receive comments from other agencies and affected 
members of the regulated and international communities during the 
comment period.

J. Privacy Act

    Anyone is able to search the electronic form of any written 
communications and comments received into any of our dockets by the 
name of the individual submitting the document (or signing the 
document, if submitted on behalf of an association, business, labor 
union, etc.). You may review DOT's complete Privacy Act Statement in 
the Federal Register published on April 11, 2000 (65 FR 19477) or you 
may visit http://www.dot.gov/privacy.html.

K. International Trade Analysis

    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 in order to protect the safety of the American 
public, and we have assessed the effects of the proposed rule to ensure 
that it does not exclude imports that meet this objective. Accordingly, 
this rulemaking is consistent with PHMSA's obligations under the Trade 
Agreement Act, as amended.

requirements.

* * * * *
    (d) A final rule published in the Federal Register on [PUBLICATION 
DATE OF FINAL RULE], effective January 1, 2009, resulted in revisions 
to this subchapter.
    During the transition period, until January 1, 2010, as provided in 
paragraph (d)(1) of this section, a person may elect to comply with 
either the applicable requirements of this subchapter in effect on 
December 31, 2008, or the requirements published in the [PUBLICATION 
DATE OF FINAL RULE] final rule.
    (1) Transition dates. The effective date of the final rule 
published on [PUBLICATION DATE OF FINAL RULE] is January 1, 2009. A 
delayed compliance date of January 1, 2010, is authorized. Unless 
otherwise specified, on and after January 1, 2010, all applicable 
regulatory requirements adopted in the final rule in effect on January 
1, 2009, must be met.
    (2) Intermixing old and new requirements. Marking, labeling, 
placarding, and shipping paper descriptions must conform to either the 
old requirements of this subchapter in effect on December 31, 2008, or 
the new requirements of this subchapter in the final rule [PUBLICATION 
DATE OF FINAL RULE] without intermixing communication elements, except 
that intermixing is permitted during the applicable transition period 
for packaging, hazard communication and handling provisions, as 
follows:

    130 For other than a dry battery specifically covered by another 
entry in the Sec.  172.101 Table, ``Batteries, dry, sealed, n.o.s.'' 
are not subject to any other requirements of this subchapter except for 
the following:
    (1) The incident reporting requirements in Sec. Sec.  171.15 and 
171.16;
    (2) Batteries and each battery-powered device or equipment 
containing such batteries must be prepared and packaged for transport 
so as to prevent:
    (i) The potential of a dangerous evolution of heat;
    (ii) Short circuits, including but is not limited to the following:
    (a) Packaging each battery or each battery-powered device or 
equipment when practicable in fully enclosed inner packagings made of 
non-conductive material;
    (b) Separating batteries and battery-powered devices in a manner to 
prevent contact with other batteries, devices or conductive materials 
(e.g., metal) in the packagings; or
    (c) Ensuring exposed terminals or connectors are individually 
protected with non-conductive caps, non-conductive tape, or by other 
appropriate means; and
    (iv) Damage to terminals. If not impact resistant, the outer 
packaging should not be used as the sole means of protecting the 
battery terminals from damage or short circuiting. Batteries must be 
securely cushioned and packed to prevent any shifting which could 
loosen terminal caps or reorient the terminals to produce short 
circuits. Terminal protection methods include but are not limited to 
the following:
    (a) Securely attaching covers of sufficient strength to protect the 
terminals;
    (b) Packaging the battery in a rigid plastic packaging; or
    (c) Constructing the battery with terminals that are recessed or 
otherwise protected so that the terminals will not be subjected to 
damage if the package is dropped; and
    (3) When transported by aircraft,
    (i) Packaged in a manner that prevents unintentional activation, 
(e.g. adequate packaging, switch caps or locks, recessed switches, 
trigger locks, temperature sensitive circuit breakers, etc.); and
    (ii) The air waybill must contain the words, ``not restricted.''

    42. Section 173.230 is revised to read as follows:


Sec.  173.230  Fuel cell cartridges containing hazardous material.

    (a) Requirements for fuel cell cartridges. Fuel cell cartridges, 
including when contained or packed with equipment, must be designed and 
constructed to prevent fuel leakage under normal conditions of 
transportation and be free of electric charge generating components. 
Fuel cell cartridge design types using liquids as fuels must pass an 
internal pressure test at a gauge pressure of 100 kPa (15 psig) without 
leakage. Except for fuel cell cartridges containing hydrogen in metal 
hydride which must be in conformance with paragraph (d) of this 
section, each fuel cell cartridge design type including when contained 
in or packed with equipment, must pass a 1.2 meter (3.9 feet) drop test 
onto an unyielding surface in the orientation most likely to result in 
the failure of the containment system with no loss of contents. Fuel 
cells installed in or integral to a fuel cell system are regarded as 
contained in equipment. Fuel cell cartridges containing a Division 2.1, 
Division 4.3 or Class 8 material must meet the following additional 
requirements.
    (b) A fuel cell cartridge designed to contain a Division 4.3 or a 
Class 8 material may contain an activator provided it is fitted with 
two independent means of preventing unintended mixing with the fuel 
during transport.
    (c) Each fuel cell cartridge designed to contain a liquefied 
flammable gas must:
    (1) Be capable of withstanding, without leakage or bursting, a 
pressure of at least two times the equilibrium pressure of the contents 
at 55 [deg]C (131 [deg]F);
    (2) Contain no more than 200 mL of liquefied flammable gas with a 
vapor pressure not exceeding 1,000 kPa (150 psig) at 55 [deg]C (131 
[deg]F); and
    (3) Pass the hot water bath test prescribed in accordance with 
Sec.  173.306(a)(3)(v).
    (d) Each fuel cell cartridge designed to contain hydrogen in a 
metal hydride must conform to the following:
    (1) Each fuel cell cartridge must have a water capacity less than 
or equal to 120 mL (4 fluid ounces).
    (2) Each fuel cell cartridge must be capable of withstanding, 
without leakage or bursting, a pressure of at least two times the 
design pressure of the cartridge at 55 [deg]C (131 [deg]F) or 200 kPa 
(30 psig) more than the design pressure of the cartridge at 55 [deg]C 
(131 [deg]F), whichever is greater. The pressure within the fuel cell 
cartridge must not exceed 5 MPa (650 psig) at 55 [deg]C (131 [deg]F). 
The pressure at which the test is conducted is referred to as the 
``minimum shell burst pressure.''
    (3) Each fuel cell cartridge must be filled in accordance with the 
procedure provided by the manufacturer. The manufacturer must provide 
the following information with each fuel cell cartridge:
    (i) Inspection procedures to be carried out before initial filling 
and before refilling of the fuel cell cartridge;
    (ii) Safety precautions and potential hazards to be aware of;
    (iii) A method of determining when the rated capacity has been 
achieved;
    (iv) Minimum and maximum pressure range;
    (v) Minimum and maximum temperature range; and
    (vi) Any other requirements to be met for initial filling and 
refilling including the type of equipment to be used.
    (4) Each fuel cell cartridge must be permanently marked with the 
following information:
    (i) The rated charging pressure in megapascals (MPa);
    (ii) The manufacturer's serial number of the fuel cell cartridges 
or unique identification number; and
    (iii) The expiration date based on the maximum service life (yyyy/
mm).
    (5) Each fuel cell cartridge design type must be subjected to and 
pass the following tests (this includes cartridges integral to a fuel 
cell):
    (i) Drop test. A 1.8 m (5.9 feet) drop test onto an unyielding 
surface must be performed. There must be no leakage. Leakage must be 
determined using a soap bubble solution or other equivalent means on 
all possible leak locations, when the fuel cell cartridge is charged to 
its rated charging pressure. The fuel cell cartridge must then be 
hydrostatically pressurized to destruction. The burst pressure must be 
greater than 85% of the minimum shell burst pressure. The drop must be 
performed in the following four different orientations:
    (A) Vertically, on the end containing the shut-off valve assembly;
    (B) Vertically, on the end opposite to the shut-off valve assembly;
    (C) Horizontally, onto a steel apex with a diameter of 3.8 cm (9.7 
in), with the steel apex in the upward position; and
    (D) At a 45[deg] angle on the end containing the shut-off valve 
assembly.
    (ii) Fire test. Each fuel cell cartridge filled (with hydrogen) to 
rated capacity must be subjected to a fire engulfment test. The 
cartridge design (including design types with an integral vent feature) 
is deemed to pass the fire test if:
    (A) The internal pressure vents to zero gauge pressure without the 
rupture of the cartridge; or
    (B) The cartridge withstands the fire for a minimum of 20 minutes 
without rupture.
    (iii) Hydrogen cycling test. Each fuel cell cartridge must be 
subjected to a hydrogen cycling test to ensure that the design stress 
limits are not exceeded during use. The fuel cell cartridge must be 
cycled from not more than 5% rated hydrogen capacity to not less than 
95% rated hydrogen capacity and back to not more than 5% rated hydrogen 
capacity. The rated charging pressure used for charging and 
temperatures must be within the operating temperature range. The 
cycling must be continued for at least 100 cycles. Following the 
cycling test the fuel cell cartridge must be charged and the water 
volume displaced by the cartridge must be measured. The design is 
deemed to pass the test if the water volume displaced by the cycled 
cartridge does not exceed the water volume displaced by an uncycled 
cartridge charged to 95% rated capacity and pressurized to 75% of its 
minimum shell burst pressure.
    (iv) Production leak test. Each fuel cell cartridge must be tested 
for leaks at 15 [deg]C  5 [deg]C (59 [deg]F  20 
[deg]F) while

[[Page 44858]]

pressurized to its rated charging pressure. There must be no leakage. 
Leakage must be determined using a soap bubble solution or other 
equivalent means on all possible leak locations.
    (e) The following packagings are authorized provided the general 
packaging requirements subpart B of part 173 of this subchapter are

this section and the applicable ISO standard. Compliance with the 
filling limits may be determined by referencing the numerical values 
and data in Table 2 of P200 of the UN Recommendations (IBR, see Sec.  
171.7 of this subchapter). Alternatively, the maximum allowable filling 
limits may be determined as follows:
    (1) For high pressure liquefied gases, in no case may the filling 
ratio of the settled pressure at 65 [deg]C (149 [deg]F) exceed the test 
pressure of the UN pressure receptacle.
    (2) For low pressure liquefied gases, the filling factor (maximum 
mass of contents per liter of water capacity) must be less than or 
equal to 95 percent of the liquid phase at 50 [deg]C. In addition, the 
UN pressure receptacle may not be liquid full at 60 [deg]C. The test 
pressure of the pressure receptacle must be equal to or greater than 
the vapor pressure of the liquid at 65 [deg]C.
    (3) For high pressure liquefied gases or gas mixtures, the maximum 
filling ratio may be determined using the formulas in (3)(b) of P200 of 
the UN Recommendations.
    (4) For low pressure liquefied gases or gas mixtures, the maximum 
filling ratio may be determined using the formulas in (3)(c) of P200 of 
the UN Recommendations.
    (c) Tetraflouroethylene, stabilized, UN1081 must be packaged in a 
pressure receptacle with a minimum test pressure of 200 bar and a

that will assure uniformity of the completed container. No used 
material other than production residues or regrind from the same 
manufacturing process may be used. The packaging must be adequately 
resistant to aging and to degradation caused either by the substance 
contained or by ultraviolet radiation.
    (b) [Reserved]


Sec.  178.33b-7  Design qualification test.

    (a) Drop testing.
    (1) To ensure that creep does not affect the ability of the 
container type to retain the contents, each container type shall be 
drop tested as follows: three groups of twenty-five filled containers 
shall be dropped from 1.8m on to a rigid, non-resilient, flat and 
horizontal surface. One group must be conditioned at 38 [deg]C (100 
[deg]F) for 26 weeks, the second group for 100 hours at 50 [deg]C (122 
[deg]F) and the third group for 18 hours at 55 [deg]C (131 [deg]F), 
prior to performing the drop test.
    (2) Criteria for passing the drop test: the containers must not 
break or leak.
    (b) [Reserved]


Sec.  178.33b-8  Production Tests.

    (a) Burst testing.
    (1) One out of each lot of 5,000 containers or less, successively 
produced per day must be pressure tested to destruction and must not 
burst below 240 psig. The container tested must be complete as intended 
for transportation.
    (2) Each such 5,000 containers or less, successively produced per 
day, shall constitute a lot and if the test container shall fail, the 
lot shall be rejected or ten additional containers may be selected at 
random and subjected to the test under which failure occurred. These 
containers shall be complete as intended for transportation. Should any 
of the ten containers thus tested fail, the entire lot must be 
rejected. All containers constituting a lot shall be of like material, 
size, design construction, finish, and quality.
    (b) Leak testing.
    (1) Each empty container must be subjected to a pressure equal to 
or in excess of the maximum expected in the filled containers at 55 
[deg]C (131 [deg]F) 50 [deg]C (122 [deg]F) if the liquid phase does not 
exceed 95 percent of the capacity of the container at 50 [deg]C (122 
[deg]F). This must be at least two-thirds of the design pressure of the 
aerosol dispenser. If any container shows evidence of leakage at a rate 
equal to or greater than 3.3 x 10-2mbar.l.s-1 at 
20 [deg]C (68 [deg]F), at the test pressure, distortion or other 
defect, it must be rejected.
    (2) Prior to filling, the filler must ensure that the crimping 
equipment is set appropriately and the specified propellant is used. 
Once filled, each container must be weighed and leak tested. The leak 
detection equipment must be sufficiently sensitive to detect at least a 
leak rate of 2.0 x 10-3 mbar.l.s-1 at 20 [deg]C 
(68[deg]F). Any filled container which shows evidence of leakage, 
deformation, or excessive weight must be rejected.

designed for stacking, the figure ``0'' must be shown. For IBCs 
designed for stacking, the maximum permitted stacking load applicable 
when the IBC is in use shall be displayed on a symbol for all IBCs 
manufactured, repaired or remanufactured after January 1, 2011 as 
follows:
[GRAPHIC] [TIFF OMITTED] TP31JY08.017

    (B) The symbol shall be not less than 100 mm (3.9 inches) x 100 mm 
(3.9 inches), be durable and clearly visible. The letters and numbers 
shall be at least 12 mm high (.48 inches). The mass marked above the 
symbol shall not exceed the load imposed during the design test divided 
by 1.8.

Sec.  178.810  Drop test.

* * * * *
    (e) Criteria for passing the test. For all IBC design types, there 
may be no damage which renders the IBC unsafe to be transported for 
salvage or for disposable, and no loss of contents. The IBC shall be 
capable of being lifted by an appropriate means until clear of the 
floor for five minutes. A slight discharge from a closure upon impact 
is not considered to be a failure of the IBC provided that no further 
leakage occurs. A slight discharge (e.g., from closures or stitch 
holes) upon impact is not considered a failure of the flexible IBC 
provided that no further leakage occurs after the IBC has been raised 
clear of the ground.
