    SUPPLEMENTARY INFORMATION:
    
    Background
    
        This NPRM is designed primarily to reduce regulatory burden on 
    industry by incorporating changes into the HMR based on RSPA's own 
    initiative and petitions for rulemaking submitted in accordance with 49 
    CFR 106.31. This NPRM also is consistent with the goals of the 
    President's Regulatory Reinvention Initiative. On March 4, 1995, the 
    President directed Federal agencies to perform an extensive review of 
    all agency regulations and eliminate or revise those requirements that 
    are outdated or in need of reform. In a continuing effort to review the 
    HMR for necessary revisions, RSPA is also proposing to eliminate, 
    revise, clarify and relax certain other regulatory requirements.
        The following is a section-by-section summary of the proposed 
    changes.
    
    Section-by-Section Review
    
    Part 171
    
    Section 171.7
        RSPA proposes to update the incorporation by reference of the 
    American Society of Mechanical Engineers (ASME) Code to the 1998 
    Edition. Currently, the 1992 Edition and the Addenda through December 
    31, 1993 are incorporated by reference. After a review, RSPA believes 
    that the 1998 Edition should be incorporated by reference. However, at 
    this time RSPA is not proposing to adopt any Addenda to the 1998 
    Edition of the ASME Code because we have not fully reviewed them.
    Section 171.8
        The definition for ``Aerosol'' would be revised to remove reference 
    to a ``metal'' receptacle to align the HMR with the UN Recommendations.
        RSPA proposes to revise the definition for ``EX number.'' 
    Currently, the definition states that an EX number is assigned by the 
    Associate Administrator for Hazardous Materials Safety (AAHMS) to 
    identify an explosive which has been approved. However, RSPA presently 
    assigns EX numbers to track materials evaluated by the AAHMS under the 
    provisions of Sec. 173.56, regardless of whether or not they are 
    approved under a different hazard class.
        The definition for ``Placarded car'' would be revised to remove 
    reference to a ``FUMIGATION placard.'' As used in the HMR, a railcar 
    containing lading which has been fumigated or is undergoing fumigation 
    is required to display the ``FUMIGANT marking'' shown in Sec. 173.9.
    Section 171.11
        RSPA is proposing to remove paragraph (d)(5), which requires the 
    identification of a poison material on the shipping paper. The 
    International Civil Aviation Organization (ICAO) Technical Instruction 
    already requires the shipping paper to identify subrisks and RSPA 
    believes paragraph (d)(5) is unnecessary. RSPA is proposing to add a 
    new paragraph (d)(5) to require that the original approval (EX) number 
    or traceable product code issued to an air bag inflator or seat-belt 
    pretensioner be entered on the shipping paper in association with the 
    basic description, as specified in Sec. 173.166 (c). Currently, 
    shipping papers for devices offered under the ICAO Technical 
    Instruction are not required to contain the EX number or product code 
    for an approved inflator or pretensioner. RSPA believes this shipping 
    paper provision should include air bags or seat-belt pretensioners when 
    offered and transported in the United States under the authority of 
    international regulations. Devices containing a pressure vessel and 
    transported as Division 2.2 (UN3353) would be excluded from this 
    shipping paper notation requirement. In addition, paragraph (d)(14) 
    would be revised to clarify that ``Aerosols'' transported in the U.S. 
    under the provisions of the ICAO Technical Instructions must be in 
    metal packagings if the packaging exceeds 7.22 cubic inches.
    Section 171.12
        RSPA is proposing to revise paragraph (a) to clarify that the 
    shipping paper documentation required under the International Maritime 
    Dangerous Goods Code (IMDG) or International Atomic Energy Agency 
    (IAEA) must be written in English as currently required by 
    Sec. 172.201(a)(2). Similar to the proposed change to Sec. 171.11 
    above, RSPA proposes to add paragraph (b)(5) to require that the 
    approval (EX) number or traceable product code be entered on shipping 
    papers for airbag inflators and seat belt pretensioners offered under 
    the International Maritime Dangerous Goods (IMDG) Code.
    
    Part 172
    
    Section 172.101
        Paragraphs (b)(2) and (b)(6) would be revised to clarify that 
    proper shipping names denoted with an ``A'' or ``W'' in Column (1), in 
    the HMT, may be used to describe hazardous materials transported by all 
    modes when all applicable requirements are met.
        RSPA proposes to remove paragraph (c)(8), which is specific to 
    determining
    
    [[Page 53167]]
    
    a proper shipping description for hazardous substances as it is 
    redundant with Sec. 172.101(c).
        Paragraph (c)(8) would be replaced to allow the words ``liquid'' or 
    ``solid'' to be added to a proper shipping name when a hazardous 
    material specifically listed by name may due to differing physical 
    states be a liquid or solid. This is consistent with existing 
    provisions in the UN Recommendations, the ICAO TI and the IMDG Code.
        The entry ``Chemical kits or First aid kits (containing hazardous 
    materials)'' would be separated into two individual entries for easier 
    reference. In addition, the wording ``(containing hazardous 
    materials)'' is unnecessary and would be removed.
        The entry `` 1-chloro-3-bromopropane'' would be changed to read 
    ``1-bromo-3-chloropropane'' to be in accordance with the UN 
    Recommendations.
        A new entry ``Fumigated transport vehicle or freight container, see 
    Sec. 173.9'' would be added to reference Sec. 173.9 which contains 
    requirements for transporting fumigated lading. This change would 
    facilitate the location of these requirements by readers.
        For the entries, ``Polychlorinated biphenyls, liquid'' and 
    ``Polychlorinated biphenyls, solid,'' UN2315, in Column 1, the symbols 
    ``A, W'' would be removed and a new Special Provision 140 would be 
    added in Column 7. Special Provision 140 would state that the material 
    is only regulated when it meets the defining criteria for a hazardous 
    substance or a marine pollutant.
        For the entry ``Air, compressed,'' Special Provision 78 would be 
    added in Column 7 to specify that only mixtures with not more than 23.5 
    percent oxygen may be transported under this entry. An OXIDIZER label 
    is not required for mixtures containing not more than 23.5 percent 
    oxygen. This change will align the HMR with a recent amendment adopted 
    in the eleventh revised edition of the UN Recommendations. In addition, 
    for the entry ``Rare gases and oxygen mixtures, compressed,'' Special 
    Provision 79 would be added to state that this entry may not be used 
    for mixtures meeting the criteria for oxidizing gas in Sec. 171.8. RSPA 
    believes that it is more appropriate to use a generic oxidizing gas 
    entry (i.e., Compressed gas, oxidizing, n.o.s.) when such mixtures meet 
    the criteria of an oxidizing gas.
        For the entry, ``Sodium chlorate, aqueous solution,'' PG II, 
    Special Provision ``B6'' would be removed. It was pointed out to RSPA 
    that similar entries (Potassium chlorate, aqueous solution and 
    Chlorates, inorganic, aqueous solution) are not assigned this Special 
    Provision. RSPA agrees that the Special Provision was mistakenly 
    assigned.
        In response to comments submitted by the Vessel Operators Hazardous 
    Materials Association (VOHMA), in response to the NPRM of HM-215C, RSPA 
    is proposing to revise a number of HMT entries with inconsistently 
    applied Codes 34 and 95 in column 10B. These codes pertain to 
    segregation of Division 2.3 and 6.1 and Class 8 hazardous materials 
    with foodstuffs. These changes will align the HMR with the IMDG Code. 
    In total, there are twenty (20) deletions of Code 95, nine (9) 
    additions of Code 95, three (3) changes from Code 34 to 95, and three 
    (3) deletions of Code 34 from Column 10B.
    Section 172.102
        In paragraph (c)(1), a new Special Provision 78 would be added to 
    specify that the entry ``Air, compressed'' may not be used to describe 
    compressed air which contains more than 23.5% of oxygen. This change 
    would align the HMR with a recent amendment adopted in the eleventh 
    revised edition of the UN Recommendations. In addition, a new Special 
    Provision 79 would be added to specify that the entry ``Rare gases and 
    oxygen mixtures, compressed'' may not be used for gas mixtures which 
    meet the criteria for an oxidizing gas. This change would ensure that 
    the correct emergency response information is provided for mixtures 
    which meet the criteria for oxidizing gas. We are also proposing to add 
    a new Special Provision 140 to the entries ``Polychlorinated biphenyls, 
    liquid'' and ``Polychorinated biphenyl, solid,'' UN 2315 to state that 
    the material is only regulated when it meets the defining criteria for 
    a hazardous substance or marine pollutant. This change would be 
    consistent with international regulations.
        We propose, in paragraph (c)(5), to revise Special Provision N10 
    regarding lighters. Currently, approvals for lighters require the 
    approval number to be marked on the package and on the shipping papers. 
    We believe that this requirement should be contained in the 
    regulations.
    Section 172.201
        Paragraph (a)(1)(ii) would be revised to clarify that when a 
    reproduced shipping paper identifies hazardous materials entries by 
    highlighting the basic description in a contrasting color, the packing 
    group must be highlighted. The packing group is identified as a basic 
    description element by Sec. 172.202(a)(4) and (b).
    Section 172.204
        For consistency with paragraphs (a)(1), (a)(2) and the ICAO 
    Technical Instructions, paragraph (c)(1) would be revised to change the 
    word ``packed'' to read ``packaged.'' A transition period of 10 years 
    would be provided for depletion of preprinted shipping papers showing 
    the word ``packed'' to reduce costs.
    Sections 172.332 and 172.336
        In response to a petition for rulemaking from the American Trucking 
    Association (ATA) [P-1364], RSPA proposes to amend Secs. 172.332(a) and 
    172.336(b) to authorize the use of white square-on-point configurations 
    for display of identification number markings regardless of whether a 
    placard is required for that material. RSPA agrees with ATA that it is 
    unnecessarily restrictive to prevent the use of identification number 
    markings displayed on square-on-point configurations in conjunction 
    with placards.
    Section 172.504
        RSPA proposes to revise the Class 9 table entry to reference 
    Sec. 172.504(f)(9), which provides an exception from displaying a Class 
    9 placard for domestic transportation. In addition, paragraph (f)(8), 
    regarding the placarding of a material classed as a combustible liquid 
    that also meets the definition of a Class 9, would be removed. A new 
    paragraph (f)(8) would be added to provide an exception, in domestic 
    transportation, for placarding a transport vehicle displaying a POISON 
    INHALATION placard if it is already placarded with a POISON GAS 
    placard.
    Section 172.516
        Paragraph (a) would be revised by changing the wording ``motor 
    vehicle'' to ``transport vehicle'' the second time it appears in the 
    first sentence, to correct an inaccurate usage of the term ``motor 
    vehicle''. This change clarifies that each placard on a motor vehicle 
    must be clearly visible from the direction it faces, except from the 
    direction of another transport vehicle to which the motor vehicle is 
    coupled.
    Section 172.519
        Paragraph (b)(3) would be revised to clarify that text is required 
    on the DANGEROUS placard. In addition, the provision would be revised 
    to clarify that text is not required on an OXYGEN placard when the 
    specific identification number is displayed.
    
    [[Page 53168]]
    
    Section 172.604
        Paragraph (c)(2) would be revised to clarify that hazardous 
    materials transported under the proper shipping name ``Consumer 
    commodity'' do not require emergency response information, regardless 
    of whether the hazard class is ``ORM-D'' as provided by the HMR, or 
    ``9'' as provided by the ICAO Technical Instructions.
    Section 172.704
        In Sec. 172.704, paragraph (b) would be revised to add the 
    reference, ``29 CFR 1910.1200,'' in addition to 29 CFR 1910.120 of the 
    Department of Labor's Occupational Safety and Health Administration 
    (OSHA). This change is needed to clarify that any training received due 
    to OSHA's requirements need not be repeated to meet DOT training 
    requirements.
    
    Part 173
    
    Section 173.4
        RSPA proposed to revise paragraphs (a)(1)(i) (ii) and (iii) to 
    clarify that the limit of one gram for Division 6.1 material per inner 
    receptacle applies only to materials that are poisonous by inhalation. 
    In addition, RSPA proposes to add a note to Sec. 173.4(a)(6)(ii) to 
    clarify that one package need not be subjected to all of the tests 
    specified in Sec. 173.4; a separate, but identical, packaging may be 
    used for each test.
    Section 173.5
        In Sec. 173.5, paragraph (a) would be revised to grant an exception 
    from the emergency response and training requirements in subparts G and 
    H of Part 172 respectively to Class 2 agricultural products that are 
    transported over local roads between fields of the same farm. 
    Currently, agricultural products other than Class 2 materials are 
    completely excepted from the HMR when transported between fields of the 
    same farm. RSPA believes that similar relief is warranted for Class 2 
    materials.
    Section 173.7
        We are proposing to add a new paragraph (e) which would incorporate 
    and expand the existing exception in Sec. 173.62, paragraph (d) for 
    Class 1 explosives owned by the Department of Defense (DOD). Section 
    173.62, paragraph (d) would be deleted. Currently DOD is authorized to 
    ship their Class 1 materials that were packaged prior to January 1, 
    1990, without regard to the current packaging requirements in Part 178. 
    In addition to the existing exception, we are proposing to also except 
    these packagings from the marking and labeling requirements. This would 
    alleviate the need to remark and re-label DOD stockpiled hazardous 
    materials. Considering that the revised exception applies to marking 
    and labeling of DOD packagings in addition to packaging requirements, 
    RSPA believes it is more appropriate that the exceptions appear in 
    Sec. 173.7.
    Section 173.12
        In Sec. 173.12, paragraph (b)(3) would be revised to clarify that 
    materials poisonous by inhalation are not authorized for the lab pack 
    provisions.
    Section 173.13
        In Sec. 173.13, paragraph (a) would be revised to clarify that use 
    of the CARGO AIRCRAFT ONLY label is required. As discussed in the 
    preamble to Docket HM-222 [May 30,1996; 61 FR 27169], it was RSPA's 
    intention to except use of primary and subsidiary hazard labels only. 
    Hazardous materials transported under the provisions of Sec. 173.13 are 
    not authorized for transportation by passenger carrying aircraft. When 
    transported without the CARGO AIRCRAFT ONLY label, RSPA believes that 
    some packagings offered for transportation under Sec. 173.13 may 
    inadvertently be placed on a passenger carrying aircraft in violation 
    of the HMR. This change would be consistent with Sec. 172.402(c) 
    regarding display of the CARGO AIRCRAFT ONLY label.
    Section 173.32
        In Sec. 173.32, we propose to amend paragraph (e)(3) to authorize 
    smaller markings on specification portable tanks that were originally 
    authorized to be marked with letters and numerals as small as 1/8 of an 
    inch in height. The specification plates originally attached to these 
    packagings do not have sufficient space to accommodate larger size 
    markings after retesting.
    Section 173.60
        In Sec. 173.60, a new paragraph (b)(14) would be added consistent 
    with the UN Recommendations to allow large explosive articles normally 
    intended for military use, to be transported unpackaged under specific 
    conditions. This provision is currently found in Sec. 173.62 Packing 
    Instruction (PI) 130; however, the provision only applies to those 
    explosives assigned to PI 130. Inclusion of this new paragraph would 
    allow any large explosive article normally intended for military use to 
    be transported unpackaged under the specified conditions.
    Section 173.61
        In Sec. 173.61, paragraph (a) would be revised to clarify that 
    explosives may be packed with non hazardous materials that will not 
    adversely affect the explosive. RSPA believes that relaxation of this 
    provision will avoid the need for exemptions.
    Section 173.62
        In Sec. 173.62, paragraph (d) would be removed. Reference the 
    preamble discussion under Sec. 173.7.
    Section 173.150
        RSPA proposes to remove the wording ``and combustible liquids'' in 
    the first sentence of Sec. 173.150(b). Referring to combustible liquids 
    is unnecessary because there is no requirement for labeling or 
    specification packaging. In addition, paragraph (f)(3)(iv) would be 
    revised to clarify that placards are not required for a combustible 
    liquid that is a hazardous substance, hazardous waste or marine 
    pollutant in a non-bulk packaging.
        We propose to revise paragraph (f)(3)(viii) by changing a reference 
    from Sec. 177.834 to Sec. 177.834(j). Paragraph (j) requires that 
    manholes and valves be closed during transportation. This proposed 
    change would clarify that combustible liquids are not subject to other 
    provisions of Sec. 177.834, such as those pertaining to attendance, and 
    is responsive to a petition for rulemaking (P-1386) from the Petroleum 
    Marketers Association of America.
    Section 173.166
        We propose to revise the introductory text in paragraph (e) to 
    clarify that all airbag modules and inflators and seat belt 
    pretensioners including those in Division 2.2 that are transported 
    under UN 3353 must be packaged in UN packagings meeting the Packing 
    Group III performance level. At present, since no packing group is 
    provided in Sec. 172.101 for UN 3353, the required level of testing for 
    UN packagings authorized for use in paragraph (e) for devices 
    transported under UN 3353 is not stated in the HMR. The proposal to 
    require a Packing Group III performance level is consistent with the 
    provisions in the eleventh revised edition of the UN Recommendations.
        We also propose to authorize an air bag module or a seat belt 
    pretensioner that has been removed from a motor vehicle that was 
    manufactured as required for use in the United States to be offered for 
    transportation in commerce without marking the EX number or product 
    code on the shipping paper, as required by current paragraph (c). 
    Instead, the word ``Recycled'' would
    
    [[Page 53169]]
    
    be entered immediately after the basic description prescribed in 
    Sec. 172.202. This proposed change will facilitate transportation of 
    these devices for recycling and eliminate the need for exemption, DOT-E 
    12189 granted to the Automotive Recyclers Association and several other 
    grantees.
    Section 173.242
        In paragraph (c)(1), a reference to obsolete Sec. 178.253-4 would 
    be removed and replaced with the specific portable tank venting 
    requirements that were contained in that section.
    Section 173.247
        Paragraph (g)(1)(iii)(C) would be revised to clarify the pressure 
    relief device requirements for bulk packagings transported by rail. The 
    current regulatory text may be misunderstood as requiring the use of a 
    combination pressure relief device, such as a reclosing pressure relief 
    device (a safety valve) incorporating a rupture disc on the upstream 
    side. The paragraph would be revised to clarify the requirement for a 
    nonreclosing pressure relief device that incorporates a rupture disc 
    conforming to the requirements of Sec. 179.15.
    Section 173.306
        Paragraph (h)(2) would be revised to clarify that shipping papers 
    are required for a Class 2 material that has been reclassed as a 
    consumer commodity if it also meets the definition for ``marine 
    pollutant.'' This change would provide consistency with corresponding 
    HMR limited quantity provisions.
    Section 173.307
        Paragraph (a)(4) would be revised to except from the HMR, 
    refrigerating machines, including dehumidifiers and air conditioners 
    and components thereof, containing up to 12 kg (25 pounds) or less of a 
    non-flammable, non-toxic gas; 12 L (3 gallons) or less of ammonia 
    solution (UN2672) and except for air transportation, 12 kg (25 pounds) 
    of flammable non-toxic gas, and 20 kg (44 pounds) or less of a Group A1 
    refrigerant specified in ANSI/ASHRAE Standard 15. In addition, for air 
    transportation consistent with Special Provision A103 of the ICAO 
    Technical Instructions an exception would be provided for refrigerating 
    machines containing 100 g (4 ounces) or less of a flammable, non-toxic 
    liquified gas. This paragraph is also revised for clarity and to 
    reference both International System of Units (SI) and customary units.
    
    Part 174
    
    Section 174.26
        The section heading would be revised by removing the phrase ``of 
    placarded cars.'' This change clarifies that the prescribed shipping 
    paper requirements apply to any person who accepts hazardous materials 
    for transportation by rail.
    Section 174.50
        As set forth in Sec. 174.50, the Federal Railroad Administration 
    (FRA) has authority to approve for movement a tank car not conforming 
    to the HMR. Since the adoption of the provision, FRA has issued 
    approximately 400 movement approvals for tank cars that no longer 
    conform to the regulations, for reasons such as leaking fittings, 
    accident damage and exceeding the gross rail load. RSPA proposes to 
    expand FRA's approval authority from tank cars to all rail cars. This 
    would allow FRA to grant approval for the movement of covered hopper 
    cars, gondola cars, and other types of railroad equipment when they no 
    longer conform to Federal law, but may safely be moved to a repair 
    location and eliminate the need for exemption for such movements.
    
    Part 175
    
    Section 175.25
        Paragraph (a)(2)(ii) would be revised to authorize lettering of at 
    least 4 mm (.16 inch) in height, based on RSPA initiative. Currently, 
    the height requirement is 6mm (0.2 inch) minimum for some of the 
    information required on the notification to air passengers of hazardous 
    materials restrictions. The smaller lettering does not significantly 
    impact readability and encourages use of space on signs for other 
    information such as graphics.
    Section 175.30
        An exception in paragraph (d)(1) for inspecting packages of 
    consumer commodities packaged in a freight container would be expanded 
    to include consumer commodities that are palletized or overpacked. RSPA 
    believes that it is impracticable for consumer commodities that are 
    palletized or overpacked to be broken down and inspected by the 
    operator of the aircraft. This amendment would allow consumer 
    commodities that are overpacked or palletized to be handled in the same 
    manner as consumer commodities in freight containers.
    
    Part 177
    
    Section 177.848
        Paragraph (c) would be revised to clarify that the prohibition 
    against loading or storing cyanides or cyanide mixtures with acids 
    applies only if hydrogen cyanide would be generated when the materials 
    come into contact with each other.
    
    Part 178
    
    Section 178.3
        RSPA proposes to amend the introductory text to paragraph (a) to 
    clarify that the specification markings on a UN standard packaging may 
    not be marked on a removable component of a packaging.
    Section 178.345-13
        In paragraph (a), a reference to obsolete Secs. 178.346-13(a), 
    178.347-13(a), and 178.348-13(a) would be removed.
    Section 178.603
        RSPA proposes to revise paragraph (f)(5) to allow a slight 
    discharge from a closure if it ceases immediately after impact with no 
    further leakage. Currently this allowance applied only to drums, 
    jerricans or bags. This proposed change would align the criteria for 
    passing the drop test with international regulations.
    Section 178.605
        RSPA proposes to revise the last sentence in paragraph (d)(1) to 
    correctly reference the maximum filling limits in Sec. 173.24a(d).
    Section 178.703
        RSPA proposes to revise Sec. 178.703(a)(1)(ii) to correctly 
    reference all of paragraph (a) of Sec. 178.702, and not merely 
    paragraphs (a)(1) and (2), for the code number used to designate an IBC 
    design type.
    Section 178.815
        Paragraph (c)(4)(iii) would be added to authorize dynamic 
    compression testing for IBCs in the same manner as is currently 
    authorized for non-bulk packagings. RSPA considers the dynamic 
    compression test to be an equivalent test method and that by allowing 
    more flexibility in the stacking test requirements will provide a cost 
    saving to the regulated industry.
    
    Part 179
    
    Section 179.100-20
        RSPA proposes to remove the water capacity entry in the table that 
    requires each DOT-105A100W tank car to be
    
    [[Page 53170]]
    
    stamped with the water capacity in pounds because it is redundant. 
    Section 179.22 requires a tank car to be marked in accordance with 
    Appendix C of the Association of American Railroads (AAR) Tank Car 
    Manual. Section C3.03 of the AAR manual already requires marking the 
    water capacity, in gallons and liters, on the side of the tank car. 
    Consequently, the requirement proposed for deletion is redundant and 
    conflicting with other requirements. Therefore, as a result, its 
    removal will have no effect on safety.
    
    Part 180
    
    Section 180.417
        RSPA proposes to revise paragraph (a)(2) to allow a cargo tank 
    owner to retain the vehicle certification report and related papers at 
    a company's principal place of business or at the location where the 
    vehicle is housed or maintained, without obtaining prior approval from 
    the Regional Director, Office of Motor Carrier Safety, Federal Highway 
    Administration. This change offers motor carriers greater flexibility 
    in the location where these documents are retained.
    
    Regulatory Analyses and Notices
    
    A. Executive Order 12866 and DOT Regulatory Policies and Procedures
    
        This proposed rule is not considered a significant regulatory 
    action under section 3(f) of Executive Order 12866 and, therefore, was 
    not reviewed by the Office of Management and Budget. This rule is not 
    significant under the Regulatory Policies and Procedures of the 
    Department of Transportation (44 FR 11034).
        The costs and benefits associated with this proposed rule are 
    considered to be so minimal as to not warrant preparation of a 
    regulatory impact analysis or regulatory evaluation. This determination 
    may be revised as a result of public comment.
    
    B. Executive Order 12612
    
        This proposed rule has been analyzed in accordance with the 
    principles and criteria contained in Executive Order 12612 
    (``Federalism''). Federal law expressly preempts State, local, and 
    Indian tribe requirements, applicable to the transportation of 
    hazardous materials, that cover certain subjects and are not 
    substantively the same as the Federal requirements. 49 U.S.C. 
    5125(b)(1). These subjects are:
        (i) The designation, description, and classification of hazardous 
    materials;
        (ii) The packing, repacking, handling, labeling, marking, and 
    placarding of hazardous materials;
        (iii) The preparation, execution, and use of shipping documents 
    pertaining to hazardous materials and requirements respecting the 
    number, content, and placement of those documents;
        (iv) The written notification, recording, and reporting of the 
    unintentional release in transportation of hazardous materials; 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 materials.
        This proposed rule concerns the classification, packaging, marking, 
    labeling, and handling of hazardous materials, among other covered 
    subjects.
        If adopted as final, this rule would preempt any State, local, or 
    Indian tribe requirements concerning these subjects unless the non-
    Federal requirements are ``substantively the same'' (see 49 CFR 
    107.202(d)) as the Federal requirements.
        Federal law (49 U.S.C. 5125(b)(2)) provides that if DOT issues a 
    regulation concerning any of the covered subjects after November 16, 
    1990, 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. RSPA 
    requests comments on what the effective date of Federal preemption 
    should be for the requirements in this proposed rule that concern 
    covered subjects.
    
    C. Executive Order 13084
    
        This propose rule has been analyzed in accordance with the 
    principles and criteria contained in Executive Order 13084 
    (``Consultation and Coordination with Indian Tribal Governments''). 
    Because this proposed rule would not significantly or uniquely affect 
    the communities, the funding and consultation requirements of the 
    Executive Order do not apply.
    
    D. Regulatory Flexibility Act
    
        The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires an 
    agency to review regulations to assess their impact on small entities 
    unless the agency determines that a rule is not expected to have a 
    significant impact on a substantial number of small entities. This 
    proposed rule would amend miscellaneous provisions in the HMR, 
    generally to clarify those provisions and to relax requirements that 
    are overly burdensome. The proposed changes in this rule are generally 
    intended to provide relief to shippers, carriers, and packaging 
    manufacturers, some of whom are small entities (e.g., governmental 
    jurisdictions and not-for-profit organizations). The costs and benefits 
    associated with this proposed rule are considered to be so minimal as 
    to not warrant preparation of a regulatory impact analysis or 
    regulatory evaluation. Therefore, I certify that this proposal will 
    not, if promulgated, have a significant economic impact on a 
    substantial number of small entities.
    
    E. Paperwork Reduction Act
    
        Under the Paperwork Reduction Act of 1995, no person is required to 
    respond to a collection of information unless it displays a valid 
    Office of Management and Budget (OMB) control number. This NPRM does 
    not propose any new information collection burdens. The information 
    collection associated with the proposal to provide for nonconforming 
    railcars under Sec. 174.50 is currently being reported under the 
    information collection for exemption applications under Sec. 107.105. 
    Information collection requirements contained in Sec. 174.50 have been 
    approved by the OMB under control number 2137-0559.
    
    F. 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.
    
    G. Unfunded Mandates Reform Act
    
        This proposed rule does not impose unfunded mandates under the 
    Unfunded Mandates Reform Act of 1995. It does not result in costs of 
    $100 million or more to either State, local, or tribal governments, in 
    the aggregate, or to the private sector, and is the least burdensome 
    alternative that achieves the objective of the rule.
    
    H. Impact on Business Processes and Computer Systems
    
        Many computers that use two digits to keep track of dates will, on 
    January 1, 2000, recognize ``double zero'' not as 2000 but as 1900. 
    This glitch, the year 2000 problem, could cause computers to stop 
    running or to start generating erroneous data. The Year 2000 problem 
    poses a threat to the global economy in which Americans live and work. 
    With the help of the President's Council on Year 2000 Conversion, 
    Federal agencies are reaching out to increase awareness
    
    [[Page 53171]]
    
    of the problem and to offer support. We do not want to impose new 
    requirements that would mandate business process changes when the 
    resources necessary to implement those requirements would otherwise be 
    applied to the Year 2000 problem. This proposed rule does not mandate 
    business process changes or require modifications to computer systems. 
    Because this proposed rule does not affect organizations' ability to 
    respond to the Year 2000 problem, we do not intend to delay the 
    effectiveness of the requirements.

        In consideration of the foregoing, 49 CFR chapter I is proposed to 
    be amended as follows:
    
    PART 171--GENERAL INFORMATION, REGULATIONS, AND DEFINITIONS
    
        1. The authority citation for part 171 would continue to read as 
    follows:
    
        Authority: 49 U.S.C. 5101-5127, 49 CFR 1.53.
    
    
    Sec. 171.7  [Amended]
    
        2. In Sec. 171.7, in paragraph (a)(3), in the table of material 
    incorporated by reference, the entry ``ASME Code, Sections II (Parts A 
    and B), V, VIII (Division 1), and IX of 1992 Edition of American 
    Society of Mechanical Engineers Boiler and Pressure Vessel Code and 
    Addenda through December 31, 1993'' would be removed and the wording 
    ``ASME Code, Sections II (Parts A and B), V, VIII (Division 1), and IX 
    of 1998 Edition of American Society of Mechanical Engineers Boiler and 
    Pressure Vessel Code'' would be added in its place.
        3. In Sec. 171.8, the definitions of ``Aerosol,'' ``EX number'' and 
    ``Placarded car'' would be revised to read as follows:
    
    
    Sec. 171.8  Definitions and abbreviations.
    
    * * * * *
        Aerosol means any non-refillable receptacle containing a gas 
    compressed, liquefied or dissolved under pressure, the sole purpose of 
    which is to expel a nonpoisonous (other than an Division 6.1 Packing 
    Group III material) liquid, paste, or powder and fitted with a self-
    closing release device allowing the contents to be ejected by the gas.
    * * * * *
        EX number means a number preceded by the prefix ``EX'', assigned by 
    the Associated Administrator for Hazardous Materials Safety, to an item 
    that has been evaluated under the provisions of Sec. 173.56 of this 
    subchapter pertaining to explosives.
    * * * * *
        Placarded car means a rail car which is placarded in accordance 
    with the requirements of part 172 of this subchapter.
    * * * * *
        4. In Sec. 171.11, paragraph (d)(5) would be revised and a sentence 
    would be added at the end of paragraph (d)(14) to read as follows:
    
    
    Sec. 171.11  Use of ICAO Technical Instructions.
    
    * * * * *
        (d) * * *
        (5) Except for a Division 2.2 air bag, air bag module, or seat-belt 
    pretensioner, the shipping paper description must conform to the 
    requirements of Sec. 173.166(c) of this subchapter.
    * * * * *
        (14) * * * In addition, an aerosol must be in a metal packaging if 
    the packaging exceeds 7.22 cubic inches.
    * * * * *
        5. In Sec. 171.12, a sentence would be added at the end of 
    paragraph (a) and a new paragraph (b)(19) would be added to read as 
    follows:
    
    
    Sec. 171.12  Imports and export shipments.
    
        (a) * * * All shipping paper information required under paragraph

    PART 172--HAZARDOUS MATERIALS TABLE, SPECIAL PROVISIONS, HAZARDOUS 
    MATERIALS COMMUNICATIONS, EMERGENCY RESPONSE INFORMATION, AND 
    TRAINING REQUIREMENTS
    
        6. The authority citation for part 172 would continue to read as 
    follows:
    
        Authority: 49 U.S.C. 5101-5127; 49 CFR 1.53.
    
        7. In Sec. 172.101, paragraphs (b)(2), (b)(6), as redesignated at 
    64 FR 10753 effective October 1, 1999, and (c)(8) would be revised to 
    read as follows:
    
    
    Sec. 172.101  Purpose and use of hazardous materials table.
    
    * * * * *
        (b) * * *
        (2) The letter ``A'' denotes a material that is subject to the 
    requirements of this subchapter only when offered or intended for 
    transportation by aircraft, unless the material is a hazardous 
    substance or a hazardous waste. A shipping description entry preceded 
    by an ``A'' may be used to describe a material for other modes of 
    transportation provided all applicable requirements for the entry are 
    met.
    * * * * *
        (6) The letter ``W'' denotes a material that is subject to the 
    requirements of this subchapter only when offered or intended for 
    transportation by vessel, unless the material is a hazardous substance 
    or a hazardous waste. A shipping description entry preceded by
    
    [[Page 53172]]
    
    a ``W'' may be used to describe a material for other modes of 
    transportation provided all applicable requirements for the entry are 
    met.
        (c) * * *
        (8) Use of the words ``liquid'' or ``solid''. The words ``liquid'' 
    or ``solid'' may be added to a proper shipping name when a hazardous 
    material specifically listed by name may due to differing physical 
    states be a liquid or solid. When the packaging specified in Column 8 
    is inappropriate for the physical state of the material the table 
    provided in paragraph (i)(4) of this section should be used to 
    determine the appropriate packaging section.
    * * * * *
    
    
    Sec. 172.101  [Amended]
    
        8. In addition, in Sec. 172.101, in the Hazardous Materials Table, 
    the following changes would be made:
        a. For the entry ``Air, compressed'', Special Provision ``78'' 
    would be added in column 7.
        b. For the entry, ``Polychlorinated biphenyls, liquid, UN2315'' in 
    Column (1) Symbols, ``A, W'' would be removed and Special Provision 
    ``140'' would be added in column 7 in numerical order.
        c. For the entry, ``Polychlorinated biphenyls, solid, UN2315'' in 
    Column (1) Symbols ``A, W'' would be removed and Special Provision 
    ``140'' would be added in column 7 in numerical order.
        d. For the entry, ``Sodium chlorate, aqueous solution'', PG II, 
    Special Provision ``B6,'' would be removed in column 7.
        9. In Sec. 172.101, the Hazardous Materials Table would be amended 
    by removing and adding, in appropriate alphabetical sequence, the 
    following entries to read as follows:
    
    
    Sec. 172.101  Purpose and use of hazardous materials table.

        (iii) The packaging may be tested using a dynamic compression 
    testing machine. The test must be conducted at room temperature on an 
    empty, unsealed packaging. The test sample must be centered on the 
    bottom platen of the testing machine. The top platen must be lowered 
    until it comes in contact with the test sample. Compression must be 
    applied end to end. The speed of the compression tester must be one-
    half inch plus or minus one-fourth inch per minute. An initial preload 
    of 50 pounds must be applied to ensure a definite contact between the 
    test sample and the platens. The distance between the platens at this 
    time must be recorded as zero deformation. The force ``A'' to then be 
    applied must be calculated using the applicable formula:
    
    Liquids: A=(n-1)[w+(s x v x 8.3 x .98)] x 1.5; or
    Solids: A=(n-1)[w+(s x v x 8.3 x .95)] x 1.5
    Where:
    A=applied load in pounds.
    n=minimum number of containers that, when stacked, reach a height of 3 
    m.
    s=specific gravity of lading.
    w=maximum weight of one empty container in pounds.
    v=actual capacity of container (rated capacity + outage) in gallons.
    And:
    8.3  corresponds to the weight in pounds of 1.0 gallon of water.
    1.5  is a compensation factor that converts the static load of the 
    stacking test into a load suitable for dynamic compression testing.

    related papers or the alternative report authorized by paragraph 
    (a)(3)(i) or (ii) of this section and retain the documents as specified 
    in this paragraph. A motor carrier who is not the owner of a cargo tank 
    motor vehicle must also retain a copy of the vehicle certification 
    report for as long as the cargo tank motor vehicle is used by that 
    carrier and for one year thereafter. The vehicle certification report 
    and related papers must be maintained at the company's principal place 
    of business or at the location where the vehicle is housed or 
    maintained. The provisions of this section do not apply to a motor 
    carrier who leases a cargo tank for less than 30 days.
