    ACTION: Notice of proposed rulemaking (NPRM).
    
    -----------------------------------------------------------------------
    
    SUMMARY: RSPA proposes to amend the Hazardous Material Regulations to 
    prohibit the carriage of oxidizers, including compressed oxygen, in 
    passenger carrying aircraft and in Class D compartments on cargo 
    aircraft. This proposal specifically analyzes the prohibition of 
    oxidizers in Class D cargo compartments. RSPA plans to issue a 
    supplemental notice of proposed rulemaking further analyzing the 
    prohibition on the carriage of oxidizers aboard passenger carrying 
    aircraft in Class B and C cargo compartments. RSPA is also proposing to 
    add a shipping description to the Hazardous Materials Table for 
    chemical oxygen generators and to require approval of a chemical oxygen 
    generator that is transported with its means of initiation attached. 
    These requirements would apply to foreign and domestic aircraft 
    entering, leaving, or operating within the United States. The purpose 
    of these proposals is to enhance air transportation safety.
    
    DATES: Comments must be received by February 28, 1997.
    
    ADDRESSES: Address comments to the Dockets Unit, Research and Special 
    Programs Administration, U.S. Department of Transportation, room 8421,

    SUPPLEMENTARY INFORMATION:
    
    I. Background
    
        The National Transportation Safety Board (NTSB) is investigating 
    the May 11, 1996, crash of a passenger-carrying aircraft which resulted 
    in 110 fatalities. Preliminary evidence indicates that chemical oxygen 
    generators were carried as cargo on board the aircraft and may have 
    caused or contributed to the severity of the accident. On May 24, 1996, 
    RSPA published an interim final rule (IFR) in the Federal Register (61 
    FR 26418) under Docket HM-224 which temporarily prohibits the offering 
    for transportation and transportation of chemical oxygen generators as 
    cargo aboard in passenger carrying aircraft. The period for submitting 
    comments on the interim final rule in Docket HM-224 closed July 23, 
    1996. After completing evaluation of the comments received, and the 
    risks posed by oxygen generators, RSPA will issue a final rule under 
    Docket HM-224 to make the prohibition permanent, terminate or modify 
    the prohibition, or otherwise amend provisions of the Hazardous 
    Materials Regulations (HMR; 49 CFR Parts 171 through 180) that apply to 
    oxygen generators. The proposal in this NPRM for amendments to 49 CFR 
    171.11 and 172.101 are based on the existing (temporary) prohibition 
    against transporting chemical oxygen generators as cargo aboard 
    passenger carrying aircraft. These proposals may be modified in a final 
    rule, as appropriate, to consider the further final rule to be issued 
    under Docket HM-224.
        On May 31, 1996, NTSB issued two recommendations to RSPA, as 
    follows:
        In cooperation with the Federal Aviation Administration, 
    permanently prohibit the transportation of chemical oxygen generators 
    as cargo on board any passenger or cargo aircraft when the generators 
    have passed their expiration dates, and the chemical core has not been 
    depleted. (Class I, Urgent Action) (A-96-29)
        In cooperation with the Federal Aviation Administration, prohibit 
    the transportation of oxidizers and oxidizing materials (e.g., nitric 
    acid) in cargo compartments that do not have fire or smoke detection 
    systems. (Class I, Urgent Action) (A-96-30)
        The actions proposed in this notice are responsive, in part, to the 
    NTSB recommendations and are based on RSPA's preliminary assessment of 
    the hazards posed by oxidizers. In its recommendations to RSPA, the 
    NTSB cited three previous incidents in which oxidizers caused fires 
    aboard aircraft. In each of these incidents, there were apparent or 
    known serious violations of the HMR. RSPA and FAA are not aware of any 
    fire aboard an aircraft having been caused directly by transport of 
    oxidizers in conformance with the HMR. However, RSPA and FAA agree with 
    the NTSB that, in certain circumstances, oxidizers can contribute to 
    the severity of a fire and may pose an unreasonable risk when 
    transported in inaccessible cargo compartments which are not required 
    to be equipped with fire or smoke detection systems or fire suppression 
    (i.e., fire-extinguishing) systems.
    
    II. Cargo Compartments Aboard Aircraft
    
        Various design features incorporated into a cargo compartment's 
    design are intended to control or extinguish any fire which might occur 
    in that compartment. Under the Federal Aviation Regulations (FAR), 
    cargo compartments are classified into five categories, Classes A, B, 
    C, D, and E (see 14 CFR 25.857). In brief, a Class A compartment is one 
    which is easily accessible in flight and in which the presence of a 
    fire would be easily discovered by a crewmember. A Class B compartment 
    is one in which any part of the compartment is accessible in flight to 
    a crewmember with a hand held fire extinguisher and has an approved 
    smoke detector or fire detector system. A Class C compartment is not 
    accessible but has an approved smoke detector or fire detector system, 
    an approved built-in fire-extinguishing system, means to control 
    ventilation so that the extinguishing agent can control any fire that 
    may start within the compartment, and means to exclude hazardous 
    quantities of smoke, flames or extinguishing agent from any compartment 
    occupied by crew or passengers.
        A Class D compartment is not accessible but is one in which a fire 
    occurring in it will be completely confined without endangering the 
    safety of the airplane or the occupants, ventilation is controlled so 
    that any fire likely to occur will not progress beyond safe limits, 
    compartment volume does not exceed 1,000 cubic feet, and there are 
    means to exclude hazardous quantities of smoke, flames or noxious gases 
    from any compartment occupied
    
    [[Page 68956]]
    
    by crew or passengers. A Class D compartment is not required to have a 
    fire or smoke detection system or a fire suppression system. Its design 
    is intended to confine and control the severity of a fire. It generally 
    is not sealed sufficiently to extinguish a fire, but is designed to 
    limit air flow enough to prevent a significant fire. For a compartment 
    of 500 cubic feet (cu. ft.) or less, an air flow of 1500 cu. ft. per 
    hour (three air exchanges per hour) is acceptable.
        A Class E compartment is one used on cargo-only aircraft which has 
    an approved smoke or fire detection system, means to shut off the 
    ventilating airflow and means to exclude hazardous quantities of smoke, 
    flames or noxious gases from the flight crew compartment.
    
    III. Oxidizers Under the HMR
    
        Under the HMR, an oxidizer (Division 5.1) is a material that may, 
    generally by yielding oxygen, cause or enhance the combustion of other 
    materials (see 49 CFR 173.127). Materials in Division 5.1 are 
    subdivided into Packing Groups I, II, or III, a relative ranking 
    corresponding to high, moderate or low risks posed by the material. 
    Packing groups are assigned to specifically named materials in the 
    Sec. 172.101 Hazardous Materials Table (Table). For generic entries, 
    such as ``Oxidizing solid, n.o.s.'' (``n.o.s.'' means ``not otherwise 
    specified''), packing groups are assigned by analogy with existing 
    entries in the Table for liquids, and by test results for solids. 
    Certain gases (Class 2), most notably oxygen, are also oxidizers under 
    the HMR and, even though they are not classed as such, they are 
    required to be identified with the OXIDIZER or OXYGEN label.
    
    IV. Oxidizers Aboard Aircraft
    
        Liquid oxidizers in Packing Group I are very reactive and have the 
    ability to initiate and substantially intensify fires. These materials 
    are forbidden for transportation by passenger-carrying aircraft and are 
    permitted only in restricted quantities aboard cargo-only aircraft. 
    Most oxidizers will not initiate fires when spilled or released, but 
    will intensify fires from other sources. Many of these materials are 
    permitted for transport aboard passenger-carrying and cargo-only 
    aircraft. When transported by aircraft, these materials are subject to 
    per package quantity limits specified in the Table, and to aircraft 
    quantity limits specified in Sec. 175.75.
        Oxidizers currently authorized for transportation by aircraft in 
    Class D cargo compartments generally will not initiate a fire. The 
    potential hazard posed by them is that, if a fire were to occur 
    elsewhere in the compartment, in the absence of a fire suppression 
    system, the fire may burn long enough to involve the oxidizer. The 
    oxidizer would then provide an oxygen-enriched environment which could 
    intensify the fire and override the limited safety features of the 
    compartment.
        In the absence of a fire caused by another source, oxidizers 
    currently authorized for air transportation and offered in conformance 
    with the HMR present very little risk to aircraft, crew or passengers. 
    The threat of a serious risk arises from the mixing of oxidizers with 
    baggage and other cargo which are potential sources of fire. Over the 
    past twenty years, virtually all fires aboard aircraft in passenger 
    baggage or cargo involved forbidden materials or serious violations of 
    the HMR.
    
    V. Prohibition of Oxidizers Aboard Aircraft in Class D Cargo 
    Compartments
    
        Knowledge of the May 11, 1996, crash has increased awareness of the 
    hazards posed by hazardous materials in transportation, and increased 
    the vigilance on the part of the public, airlines, commercial shippers 
    and the Federal Government. While this should result in fewer instances 
    involving transportation of forbidden materials aboard aircraft, fires 
    initiated by forbidden materials in passenger baggage and cargo likely 
    will not be totally eliminated. Further, because Class D cargo 
    compartments are not required to be equipped with smoke or fire 
    detection systems or fire-extinguishing systems, oxidizers could become 
    involved in and substantially intensify a cargo compartment fire 
    thereby contributing to the severity of an incident and, possibly, the 
    loss of life and property. For these reasons, RSPA and FAA agree with 
    the NTSB recommendation to prohibit the transportation of oxidizers in 
    cargo compartments that do not have fire or smoke detection systems. 
    Therefore, RSPA proposes to amend Sec. 175.85 to prohibit the loading 
    or transportation in a Class D cargo compartment of a package for which 
    an OXIDIZER or OXYGEN label (see Secs. 172.426 and 172.405) is required 
    under Subpart E of Part 172. These restrictions would apply to both 
    foreign and domestic aircraft entering, leaving or operating in the 
    United States.
        The proposed prohibition against transportation of oxidizers as 
    cargo in Class D compartments (and the possible expansion of this 
    proposed prohibition to Class B and C compartments, as discussed in 
    Part VI, below) would not affect the exception in 49 CFR 175.10(a)(7) 
    for operator-supplied oxygen for a passenger's use during flight. 
    However, in this NPRM, RSPA is proposing an editorial change to this 
    section to clarify that this exception applies only to oxygen provided 
    for use by an onboard passenger and does not allow the air carrier to 
    transport medical oxygen devices as cargo in order to move them to the 
    locations where they will be needed, at a later time, for use by 
    passengers.
        At the present time, a passenger's own medical oxygen cylinder may 
    be transported as cargo on passenger-carrying aircraft in compliance 
    with the HMR, but the passenger's own cylinder may not be transported 
    in the passenger cabin. 49 CFR 175.85(a). If RSPA ultimately prohibits 
    the carriage of all oxidizers, including gaseous oxygen, in Class B, C, 
    and D compartments on passenger-carrying aircraft, a passenger would 
    not be able to ship its own medical oxygen on the same airplane. The 
    passenger would have to arrange for another supply of oxygen at 
    destination, rather than using a cylinder that the passenger owns.
        FAA supports a complete removal of oxidizers from passenger-
    carrying aircraft, as proposed, but also believes that, if it is 
    necessary to allow a passenger to transport its own oxygen cylinder for 
    use at destination, it is far safer to stow the cylinder in the 
    passenger cabin, under the control of and accessible to the airline 
    crew, than in an inaccessible cargo compartment. FAA does not believe 
    that it is prudent to allow for the carriage of compressed oxygen in an 
    inaccessible Class D compartment. It believes that, if an oxygen 
    cylinder is involved in a fire, the release of oxygen will intensify 
    the fire. Because the Class D cargo compartment does not contain 
    detection or suppression devices and because it is inaccessible to 
    crew, a fire that might otherwise be survivable has an increased risk 
    of becoming fatal. Thus, FAA believes that it would be safer to carry 
    personal medical oxygen cylinders in the cabin because the crew could 
    quickly remove the cylinders from any fire area in the cabin. This is 
    in contrast to the complete inability of the crew to remove compressed 
    oxygen from an inaccessible Class D cargo compartment.
        RSPA expressly invites comments on this and any other alternatives 
    (to completely prohibiting passenger-owned oxygen cylinders) that would 
    accommodate passengers with breathing difficulties that need their own 
    supply of oxygen at destination. These comments should indicate 
    whether, and how many, passengers actually ship their own medical 
    oxygen cylinders on
    
    [[Page 68957]]
    
    the same airplane in order to have a supply of oxygen at their 
    destination.
        RSPA also invites air carriers to submit comments on the effect of 
    the prohibition on current practices of using passenger-carrying 
    aircraft to ``stage'' or position the oxygen cylinders that airlines 
    provide to passengers with breathing difficulties for use during flight 
    under 49 CFR 175.10(a)(7). The proposed prohibition would have the 
    effect of requiring air carriers to ship their own cylinders by ground 
    transportation or by cargo-only aircraft, rather than using their own 
    passenger-carrying aircraft to move these devices to locations for 
    passenger use.
        FAA is working on a related action to require that Class D 
    compartments be clearly marked so that cargo-handling personnel will be 
    able to recognize them.
        RSPA and FAA have tentatively determined that the costs of the 
    requirements of this proposal would be $25 million over ten years ($17 
    million, present value). RSPA and FAA have also tentatively determined 
    that the benefits of this proposal will outweigh the costs if it saves 
    nine or more lives over the next ten years.
    
    VI. Prohibition of Oxidizers As Cargo on All Passenger Carrying 
    Aircraft
    
        RSPA is proposing to extend the prohibition on oxidizers to Class B 
    and C aircraft cargo compartments, effectively prohibiting the carriage 
    of oxidizers on passenger carrying aircraft. RSPA plans on issuing an 
    SNPRM further developing and analyzing this part of our proposed rule 
    in the very near future. Although the proposal has not been fully 
    developed, it is being proposed in this document for two reasons: (1) 
    we would like to take advantage of the intervening time to seek public 
    comment that can be used in development of the SNPRM; to the extent 
    that commenters can very quickly provide us with their comments and 
    supporting data, we will consider them in developing the SNPRM; and (2) 
    we believe that, in preparing comments on the prohibition in ``D'' 
    compartments, commenters should consider the possibility that any final 
    rule could include a prohibition on all passenger carrying aircraft.
    
    VII. Oxygen Generators: Shipping Description and Small Personal 
    Oxygen Generators
    
    A. Shipping Description
    
        Currently, under the HMR, the most appropriate shipping description 
    for an oxygen generator (chemical) containing sodium chlorate as the 
    primary constituent is ``Oxidizing solid, n.o.s., 5.1, UN1479, II.'' 
    RSPA does not believe that this name adequately describes an oxygen 
    generator. In particular, the name does not communicate to an air 
    carrier the fact that the material is not authorized on passenger 
    carrying aircraft. Therefore, consistent with changes recently adopted 
    into the International Civil Aviation Organizations Technical 
    Instructions for the Transport of Dangerous Goods By Air, RSPA proposes 
    to add the following description to the Hazardous Materials Table 
    (Table) ``Oxygen generator, chemical, 5.1 UN3353, II.'' RSPA also is 
    proposing to revise Secs. 171.11, 171.12, and 171.12a to require the 
    use of the new name in international transportation.
        The second sentence of proposed Sec. 171.11(d)(14) and the word 
    ``Forbidden'' in Column 9A of the proposed Table entry for ``Oxygen 
    generator, chemical'' are based on the existing (temporary) prohibition 
    against transporting chemical oxygen generators aboard passenger-
    carrying aircraft. These proposals may be modified in a final rule, as 
    appropriate, to consider the further final rule to be published under 
    Docket HM-224. The UN identification number assigned to the proposed 
    shipping name ``Oxygen generator, chemical'' in the Table may be 
    revised if the UN Committee of Experts on the Transport Of Dangerous 
    Goods adopts a different identification number in its Recommendations 
    on the Transport of Dangerous Goods.
        In addition, RSPA believes that the hazards posed by an oxygen 
    generator, chemical that is shipped with its means of initiation 
    attached require special approval. Therefore, consistent with the 
    prohibitions and conditions specified in Sec. 173.21, RSPA is proposing 
    a separate requirement that oxygen generator, chemical that is shipped 
    with its means of initiation attached must: (1) be classed and approved 
    by the Associate Administrator for Hazardous Materials Safety; (2) 
    incorporate at least two safety features that will prevent 
    unintentional activation of the generator; and (3) when transported by 
    air, be contained in a packaging prepared and originally offered for 
    transportation by the approval holder. RSPA is also proposing to 
    require that each shipper of an approved oxygen generator have a copy 
    of the approval and that the approval number be marked on the outside 
    of the package.
    
    B. Small Personal Oxygen Genenerators
    
        In the interim final rule RSPA published under Docket HM-224, RSPA 
    prohibited the transportation of oxygen generators by passenger 
    carrying aircraft. An exception was provided for personal oxygen 
    generators that meet the conditions of Sec. 175.10(a)(24). Section 
    175.10(a)(24) requires that the person carrying the oxygen generator 
    receive the approval of the operator of the aircraft and that the 
    personal oxygen generators conform to the following: (1) a six foot 
    drop test without loss of contents or activation; (2) be equipped with 
    at least two positive means of preventing unintentional activation; (3) 
    be well insulated, and when actuated the temperature on any external 
    surface does not exceed 212 degrees Fahrenheit; (4) be in the 
    manufacturer's original packaging which must include a sealed outer 
    wrapping or clear evidence that the generator has not been tampered 
    with; and (5) be marked to indicate conformance with 
    Sec. 175.10(a)(24).
        In its comments to the interim final rule, the Air Line Pilots 
    Association (ALPA) requested that the exception for small personal 
    oxygen generators in Sec. 175.10(a)(24) be removed. Though 
    Sec. 175.10(a)(24) requires passengers to notify operators when there 
    are oxygen generators in their baggage, ALPA stated that an aircraft 
    operator has no way of knowing that these small chemical oxygen 
    generators are being carried in a passenger's checked baggage because 
    there are no public awareness programs or procedures for notifying 
    passengers that passengers are to contact operators before they offer 
    bags containing generators as checked baggage. ALPA also stated that 
    there is no realistic way to know when or that the person who purchased 
    or who intends to carry oxygen generators has been educated in the 
    proper way to inspect and maintain them as specified in the HMR. ALPA 
    went on to say that there is no way for an operator to examine the 
    units to verify that a passenger is in compliance with these 
    requirements. ALPA also pointed out that the Civil Aviation Authority 
    of the United Kingdom has banned personal oxygen generators on 
    passenger-carrying aircraft.
        RSPA believes that adequate public notice and comment should be 
    provided before the exception in Sec. 175.10(a)(24) is removed. 
    Therefore, RSPA is proposing, in this NPRM, to remove the exception 
    provided in Sec. 175.10(a)(24) for small personal oxygen generators.
    
    VIII. Request for Additional Comments
    
        RSPA requests any available information concerning the costs and 
    benefits of this proposed action. RSPA is requesting information 
    concerning the hazards posed by oxidizers in aircraft cargo 
    compartments that have fire detection or suppression systems. Please
    
    [[Page 68958]]
    
    provide detailed cost information to RSPA as to the manner by which you 
    would incur costs as the result of the proposed ban of oxidizers 
    including all germane monetary and qualitative cost information. RSPA 
    also solicits comments from those foreign operators who would incur 
    costs as the result of this proposal. Although our evaluation has not 
    been able to determine any apparent cost impact on cargo aircraft 
    carriers, RSPA recognizes there could, nonetheless, be a potential cost 
    impact. As the result of this concern, RSPA solicits information from 
    cargo aircraft operators who find they would incur costs from 
    implementation of the proposed rule. Potentially impacted shippers are 
    asked to provide detailed information on the manner by which they would 
    incur costs.
        There may also be adverse impacts on airlines if they routinely use 
    passenger-carrying aircraft to transport, as cargo, oxygen cylinders 
    which are normally installed on aircraft and must be periodically 
    retested or refilled. RSPA has not assessed the costs associated with 
    prohibiting the shipment of oxygen cylinders on passenger carrying 
    aircraft. Therefore, RSPA requests any available information concerning 
    the costs and benefits of banning oxygen cylinders, as cargo, aboard 
    passenger carrying aircraft. Please provide detailed information as to 
    the manner by which you would incur costs. In particular, RSPA is 
    requesting information on the number of cylinders of oxygen which are 
    transported each day on passenger carrying aircraft. What is the 
    typical size of these containers? What other means of transportation 
    are available? What are the cost differences to the airlines for using 
    these other means of transportation?
        By limiting the prohibition on oxidizers to packages required to be 
    labeled OXIDIZER and OXYGEN, the prohibition would not apply to 
    oxidizers classed as consumer commodities, ORM-D, under the provisions 
    of Sec. 173.152, or as consumer commodities, Class 9, as permitted 
    under Sec. 171.11. RSPA requests comments regarding whether it would be 
    appropriate to extend this prohibition to consumer commodities which 
    are oxidizers or whether quantity limits should be imposed on these 
    materials in Sec. 175.75.
    
    IX. Future Rulemaking
    
        RSPA, in coordination with FAA, has initiated a study to assess the 
    risks associated with the transportation of hazardous materials in 
    aircraft cargo compartments. As an initial step, RSPA held a meeting in 
    Cambridge, Massachusetts on October 22, 1996, for purposes of 
    identifying accident scenarios, probabilities of occurrence, and 
    expected consequences. In attendance were representatives from the 
    NTSB, FAA, Air Transport Association, Chemical Manufacturers 
    Association, Air Line Pilots Association, International Air Line 
    Passenger Association and several aircraft manufacturers. Based on the 
    outcome of this study, RSPA may initiate a rulemaking to ban additional 
    hazardous materials. RSPA requests comments regarding whether it would 
    be appropriate to extend this prohibition to other materials which may 
    pose hazards similar to oxidizers, such as organic peroxides. Comments 
    are requested as to the costs and benefits of these possible actions.
    
    X. Regulatory Analyses and Notices
    
    Executive Order 12866 and DOT Regulatory Policies and Procedures
    
        This proposed rule is considered a significant regulatory action 
    under section 3(f) of Executive Order 12866 and was reviewed by the 
    Office of Management and Budget. The rule is considered significant 
    under the regulatory policies and procedures of the Department of 
    Transportation (44 FR 11034). A preliminary regulatory evaluation is 
    available for review in the public docket.
    
    Executive Order 12612
    
        This proposed rule has been analyzed in accordance with the 
    principles and criteria contained in Executive Order 12612 
    (``Federalism''). The Federal hazardous materials transportation law 
    (49 U.S.C. 5101-5127) contains an express preemption provision that 
    preempts State, local, and Indian tribe requirements on certain covered 
    subjects. Covered subjects are:
        (i) the designation, description, and classification of hazardous 
    material;
        (ii) the packing, repacking, handling, labeling, marking, and 
    placarding of hazardous material;
        (iii) the preparation, execution, and use of shipping documents 
    pertaining to hazardous material and requirements respecting the 
    number, content, and placement of such documents;
        (iv) the written notification, recording, and reporting of the 
    unintentional release in transportation of hazardous material; or
        (v) the design, manufacturing, fabrication, marking, maintenance, 
    reconditioning, repairing, or testing of a package or container which 
    is represented, marked, certified, or sold as qualified for use in the 
    transportation of hazardous material.
        Because RSPA lacks discretion in this area, preparation of a 
    federalism assessment is not warranted. Title 49 U.S.C. 5125(b)(2) 
    provides that DOT must determine and publish in the Federal Register 
    the effective date of Federal preemption. That effective date may not 
    be earlier than the 90th day following the date of issuance of the 
    final rule and not later than two years after the date of issuance. 
    This proposed rule would require oxidizers to be transported in certain 
    types of cargo compartments aboard aircraft. RSPA solicits comments on 
    whether the proposed rule would have any effect on State, local or 
    Indian tribe requirements and, if so, the most appropriate effective 
    date of Federal preemption.
    
    Regulatory Flexibility Act
    
        I certify that this proposed rule will not have a significant 
    economic impact on a substantial number of small entities. This 
    proposed rule applies to air carriers, most of whom are not small 
    entities.
    
    Paperwork Reduction Act
    
        This proposed rule does not propose any new information collection 
    requirements.
    
    Regulation Identifier Number (RIN)
    
        A regulation identifier number (RIN) is assigned to each regulatory 
    action listed in the Unified Agenda of Federal Regulations. The 
    Regulatory Information Service Center publishes the Unified Agenda in 
    April and October of each year. The RIN number contained in the heading 
    of this document can be used to cross-reference this action with the 
    Unified Agenda.
