    ACTION: Final rule.
    
    -----------------------------------------------------------------------
    
    SUMMARY: In this final rule, RSPA is amending the Hazardous Materials 
    Regulations (HMR) by revising the ``List of Hazardous Substances and 
    Reportable Quantities'' which appears in an Appendix to the hazardous 
    materials table. This action is necessary to comply with the Superfund 
    Amendments and Reauthorization Act (SARA) of 1986, which amended the 
    Comprehensive Environmental Response, Compensation and Liability Act of 
    1980 (CERCLA) to mandate that RSPA regulate, under the HMR, all 
    hazardous substances designated by the Environmental Protection Agency 
    (EPA). The intended effect of this action is to enable shippers and 
    carriers to identify CERCLA hazardous substances, thereby enabling them 
    to comply with all applicable HMR requirements and to make the required 
    notifications if a discharge of a hazardous substance occurs.
    
    DATES: This amendment is effective August 29, 1994. However, immediate 
    compliance with the regulations as amended herein is authorized.

    SUPPLEMENTARY INFORMATION:
    
    I. Background
    
        Section 202 of SARA (Pub. L. 99-499) amended Section 306(a) of 
    CERCLA (Pub. L. 96-510), 42 U.S.C. 9656(a), by requiring the Secretary 
    of Transportation to list and regulate hazardous substances, listed or 
    designated under Section 101(14) of CERCLA, 42 U.S.C. 9601(14), as 
    hazardous materials under the Hazardous Materials Transportation Act 
    (HMTA; 49 App. U.S.C. 1801 et seq.). RSPA carries out the rulemaking 
    responsibilities of the Secretary of Transportation under the HMTA. 49 
    CFR 1.53(b). This final rule is necessary to comply with 42 U.S.C. 
    9656(a) as amended by Section 202 of SARA.
        In carrying out that statutory mandate, RSPA has no discretion to 
    determine what is or is not a hazardous substance or the appropriate 
    reportable quantity (RQ) for materials designated as hazardous 
    substances. This authority is vested in EPA. Therefore, under the 
    CERCLA scheme EPA must issue final rules amending the list of CERCLA 
    hazardous substances, including adjusting RQ's, before RSPA can amend 
    its list of hazardous substances. In the preamble to the final rule on 
    this subject issued under Docket HM-145F (51 FR 42174; November 21, 
    1986), RSPA included the following statement:
    
        It is RSPA's intention to make changes from time to time to the 
    list of hazardous substances or their RQ's in the Appendix as 
    adjustments are made by EPA.
    
        This document adjusts the ``List of Hazardous Substances and 
    Reportable Quantities'' that appears in Appendix A to Sec. 172.101, 
    based on several final rules EPA has published. On November 2, 1990 (55 
    FR 46354), EPA published a final rule which added the waste codes F037 
    and F038 to the list of hazardous substances with RQ's of 1 pound. On 
    December 6, 1990 (55 FR 50450), EPA published a final rule which added 
    the waste codes FO32, F034, and F035 to the list of hazardous 
    substances with RQ's of 1 pound. On August 18, 1992 (57 FR 37194), EPA 
    published a final rule which added the waste codes K141, K142, K143, 
    K144, K145, K147 and K148 to the list of hazardous substances with RQ's 
    of 1 pound. On October 15, 1992 (57 FR 47376), EPA published a final 
    rule which added the waste codes K149, K150 and K151 to the list of 
    hazardous substances, with RQ's of 10 pounds. On June 30, 1993 (58 FR 
    35314), EPA published a final rule which revised the RQ for 34 
    hazardous substances. These substances include lead metal, 12 lead 
    compounds, 15 waste streams that contain lead, characteristic wastes 
    that fail the Toxicity Characteristic Leaching Procedure based on their 
    lead constituents, and methyl isocyanate. The following table 
    identifies those substances that have had their RQ's revised.

        To keep its ``List of Hazardous Substances and Reportable 
    Quantities'' consistent with EPA's list of CERCLA hazardous substances 
    and reportable quantities, RSPA is amending the HMR in accordance with 
    these EPA final rules. In addition, RSPA is making several non-
    substantive editorial changes to its ``List of Hazardous Substances and 
    Reportable Quantities.'' The RQ for ``diethylhexyl phthalate'' is being 
    revised to correctly read 100 pounds. In addition, RSPA is adding 
    ``methyl ethyl ketone'' to the list of hazardous substances as a 
    synonym for ``methyl ethyl ketone (MEK).'' RSPA is also amending the 
    entry for DO41 to correctly read ``D041 2,4,5-Trichlorophenol.'' 
    Finally, RSPA is removing the footnote ``*'' from the list of hazardous 
    substances. The footnote ``*'' symbolized that an entry also appeared 
    in the Hazardous Materials Table in 49 CFR 172.101 (HMT) as a proper 
    shipping name. However, the numerous changes to the HMT promulgated 
    under Docket No. HM-181 on December 21, 1990 (55 FR 52401) make it 
    impractical to determine if those entries in the list of hazardous 
    substances marked with the ``*'' are still proper shipping names in the 
    revised HMT.
        The paragraphs preceding the lists of hazardous substances are also 
    editorially revised to indicate that the list of hazardous substances: 
    (1) fulfills the requirement under CERCLA that all hazardous substances 
    be listed and regulated as hazardous materials under the HMTA; and (2) 
    includes substances listed under the Federal Water Pollution Control 
    Act, Solid Waste Disposal Act, Clean Air Act, and those substances 
    designated by the Administrator of EPA.
        In addition, common and contract carriers are informed that they 
    may be held liable under laws other than CERCLA for the release of a 
    hazardous substance during transportation that commenced before the 
    effective date of the listing and regulating of that substance under 
    the HMTA.
        This rulemaking will enable shippers and carriers to identify 
    CERCLA hazardous substances and thereby enable them to comply with all 
    applicable HMR requirements and to make the required notifications if a 
    discharge of a hazardous substance occurs. In addition to the reporting 
    requirements of the HMR found in Secs. 171.15 and 171.16, a discharge 
    of a hazardous substance is subject to EPA reporting requirements at 40 
    CFR 302.6 and may be subject to the reporting requirements of the U.S. 
    Coast Guard at 33 CFR 153.203.
        Because this rulemaking makes numerous modifications to the ``List 
    of Hazardous Substances and Reportable Quantities'' found in Appendix A 
    to Sec. 172.101, RSPA is reprinting ``Table 1--Hazardous Substances 
    Other than Radionuclides'' in its entirety.
    
    II. Regulatory Analyses and Notices
    
        In accordance with the Administrative Procedure Act, 5 U.S.C. 
    553(b)(3)(B), RSPA has determined that a notice of proposed rulemaking 
    and an opportunity for public comment and review are impracticable and 
    unnecessary. SARA mandates that the Department of Transportation list 
    and regulate, as hazardous materials under 49 CFR Parts 171-180, 
    hazardous substances designated by EPA under CERCLA. EPA is the sole 
    agency authorized to designate hazardous substances and their 
    reportable quantities. Therefore, public comment and review are 
    unnecessary because: (1) The public was afforded time to comment when 
    EPA published its notice of proposed rulemaking concerning that 
    agency's change in the subject RQ's; and (2) RSPA does not have the 
    authority to designate hazardous substances or determine their 
    reportable quantities.
    
    Executive Order 12866 and DOT Regulatory Policies and Procedures
    
        This final rule is not considered a significant regulatory action 
    under section 3(f) of Executive Order 12866 and, therefore, was not 
    reviewed by the Office of Management and Budget. The rule is not 
    considered significant under the regulatory policies and procedures of 
    the Department of Transportation (44 FR 11034). The economic impact of 
    this final rule is minimal to the extent that preparation of a 
    regulatory evaluation is not warranted.
    
    Executive Order 12612
    
        This final rule has been analyzed in accordance with the principles 
    and criteria contained in Executive Order 12612 (``Federalism''). The 
    Hazardous Materials Transportation Act contains an express preemption 
    provision (49 App. U.S.C. 1804(a)4)) that preempts State, local, and 
    Indian tribe requirements on certain covered subjects. Covered 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 such 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 final rule concerns the designation of hazardous materials. 
    This final rule preempts State, local, or Indian tribe requirements in 
    accordance with the standards set forth above. The HMTA (49 App. U.S.C. 
    1804(a)(5)) 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 has determined that the 
    effective date of Federal preemption for these requirements will be 
    [insert date 90 days after date of publication]. This rule is mandated 
    by CERCLA, and does not have sufficient federalism implications to 
    warrant preparation of a Federalism Assessment.
    
    Regulatory Flexibility Act
    
        I certify that this final rule will not have a significant economic 
    impact on a substantial number of small entities. This rule applies to 
    shippers and carriers of hazardous substances, some of which are small 
    entities; however, the economic impact of this rule is minimal.
    
    Paperwork Reduction Act
    
        There are no new information collection requirements in this final 
    rule.
    
    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.
    
    List of Subjects in 49 CFR Part 172
    
        Hazardous materials transportation, Hazardous wastes, Labels, 
    Markings, Packaging and containers, Reporting and recordkeeping 
    requirements.
    
        Issued in Washington, DC on June 6, 1994 under authority 
    delegated in 49 CFR part 1.
    Ana Sol Gutierrez,
    Acting Administrator, Research and Special Programs Administration.
    
        In consideration of the foregoing, Part 172 of Title 49, Code of 
    Federal Regulations, is amended as follows:
    
    PART 172--HAZARDOUS MATERIALS TABLE, SPECIAL PROVISIONS, HAZARDOUS 
    MATERIALS COMMUNICATIONS, EMERGENCY RESPONSE INFORMATION, AND 
    TRAINING REQUIREMENTS
    
        1. The authority citation for Part 172 continues to read as 
    follows:
    
        Authority: 49 App. U.S.C. 1803, 1804, 1805, 1808; 49 CFR Part 1, 
    unless otherwise noted.
    
        2. In Appendix A to Sec. 172.101, the paragraphs preceding the 
    tables, and Table 1 are revised to read as follows:
    
    Appendix A to Sec. 172.101--List of Hazardous Substances and 
    Reportable Quantities
    
        1. This Appendix lists materials and their corresponding 
    reportable quantities (RQ's) that are listed or designated as 
    ``hazardous substances'' under section 101(14) of the Comprehensive 
    Environmental Response, Compensation, and Liability Act, 42 U.S.C. 
    9601(14) (CERCLA; 42 U.S.C. 9601 et seq). This listing fulfills the 
    requirement of CERCLA, 42 U.S.C. 9656(a), that all ``hazardous 
    substances,'' as defined in 42 U.S.C. 9601(14), be listed and 
    regulated as hazardous materials under the Hazardous Materials 
    Transportation Act. That definition includes substances listed under 
    sections 311(b)(2)(A) and 307(a) of the Federal Water Pollution 
    Control Act, 33 U.S.C. 1321(b)(2)(A) and 1317(a), section 3001 of 
    the Solid Waste Disposal Act, 42 U.S.C. 6921, and section 112 of the 
    Clean Air Act, 42 U.S.C. 7412. In addition, this list contains 
    materials that the Administrator of the Environmental Protection 
    Agency has determined to be hazardous substances in accordance with 
    section 102 of CERCLA, 42 U.S.C. 9602. It should be noted that 42 
    U.S.C. 9656(b) provides that common and contract carriers may be 
    held liable under laws other than CERCLA for the release of a 
    hazardous substance as defined in that Act, during transportation 
    that commenced before the effective date of the listing and 
    regulating of that substance as a hazardous material under the 
    Hazardous Materials Transportation Act (49 App. U.S.C. 1801 et 
    seq.).
        2. This Appendix is divided into two TABLES which are entitled 
    ``TABLE 1--HAZARDOUS SUBSTANCES OTHER THAN RADIONUCLIDES'' and 
    ``TABLE 2--RADIONUCLIDES.'' A material listed in this Appendix is 
    regulated as a hazardous material and a hazardous substance under 
    this subchapter if it meets the definition of a hazardous substance 
    in Sec. 171.8 of this subchapter.
        3. The procedure for selecting a proper shipping name for a 
    hazardous substance is set forth in Sec. 172.101(c)(8).
        4. Column 1 of TABLE 1, entitled ``Hazardous substance'', 
    contains the names of those elements and compounds that are 
    hazardous substances. Following the listing of elements and 
    compounds is a listing of waste streams. These waste streams appear 
    on the list in numerical sequence and are referenced by the 
    appropriate ``D'', ``F'' or ``K'' numbers. Column 2 of TABLE 1, 
    entitled ``Synonyms'', contains the names of synonyms for certain 
    elements and compounds listed in Column 1. No synonyms are listed 
    for waste streams. Synonyms are useful in identifying hazardous 
    substances and in identifying proper shipping names. Column 3 of 
    TABLE 1, entitled ``Reportable quantity (RQ)'', contains the 
    reportable quantity (RQ), in pounds and kilograms, for each 
    hazardous substance listed in Column 1 of TABLE 1.
        5. A series of notes is used throughout TABLE 1 and TABLE 2 to 
    provide additional information concerning certain hazardous 
    substances. These notes are explained at the end of each TABLE.
        6. TABLE 2 lists radionuclides that are hazardous substances and 
    their corresponding RQ's. The RQ's in Table 2 for radionuclides are 
    expressed in units of curies and terabecquerels, whereas those in 
    Table 1 are expressed in units of pounds and kilograms. If a 
    material is listed in both Table 1 and Table 2, the lower RQ shall 
    apply. Radionuclides are listed in alphabetical order. The RQ's for 
    radionuclides are given in the radiological unit of measure of 
    curie, abbreviated ``Ci'', followed, in parentheses, by an 
    equivalent unit measured in terabecquerels, abbreviated ``TBq''.
        7. For mixtures of radionuclides, the following requirements 
    shall be used in determining if a package contains an RQ of a 
    hazardous substance: (i) if the identity and quantity (in curies or 
    terabecquerels) of each radionuclide in a mixture or solution is 
    known, the ratio between the quantity per package (in curies or 
    terabecquerels) and the RQ for the radionuclide must be determined 
    for each radionuclide. A package contains an RQ of a hazardous 
    substance when the sum of the ratios for the radionuclides in the 
    mixture or solution is equal to or greater than one; (ii) if the 
    identity of each radionuclide in a mixture or solution is known but 
    the quantity per package (in curies or terabecquerels) of one or 
    more of the radionuclides is unknown, an RQ of a hazardous substance 
    is present in a package when the total quantity (in curies or 
    terabecquerels) of the mixture or solution is equal to or greater 
    than the lowest RQ of any individual radionuclide in the mixture or 
    solution; and (iii) if the identity of one or more radionuclides in 
    a mixture or solution is unknown (or if the identity of a 
    radionuclide by itself is unknown), an RQ of a hazardous substance 
    is present when the total quantity (in curies or terabecquerels) in 
    a package is equal to or greater than either one curie or the lowest 
    RQ of any known individual radionuclide in the mixture or solution, 
    whichever is lower.
