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.

  8. 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.

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

    1. 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.

    2. 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.

    3. 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.

    4. 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.

  10. 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.

  11. 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.

  12. 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

    UN1834 Sulfuryl chloride

    UN1836 Thionyl chloride

    UN2699 Trifluoroacetic acid

    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

  13. 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

    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

    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

    9. General. Liquefied gases and gas mixtures must be offered for transportation in UN pressure receptacles subject to the requirements in this section and Sec. 173.304. In addition, the general requirements applicable to UN pressure receptacles in Sec. Sec. 173.301 and 173.301b must be met.

      (b) UN pressure receptacle filling limits. A UN pressure receptacle is authorized for the transportation of liquefied compressed gases and gas mixtures as specified in this section. When a liquefied compressed gas or gas mixture is transported in a UN pressure receptacle, the filling ratio may not exceed the maximum filling ratio prescribed in 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 working pressure not exceeding 5 bar.

    19. 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

      1. for 26 weeks, the second group for 100 hours at 50 [deg]C (122

        deg

      2. 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.

        (

    20. 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-1at 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 10-3mbar.l.s-1at 20 [deg]C

      (68[deg]F). Any filled container which shows evidence of leakage, deformation, or excessive weight must be rejected.

      Sec. 178.33b-9 Marking.

      (

    21. Each container must be clearly and permanently marked to show:

      (1) DOT-2S.

      (2) Name or symbol of person making the mark specified in paragraph

      (a)(1) of this section. Symbol, if used, must be registered with the

      Associate Administrator.

      (b) [Reserved] 59. In Sec. 178.502, paragraph (d) is revised and a note to the section is added to read as follows:

      Sec. 178.502 Identification codes for packagings.

      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.
