Hazardous Substances

AGENCY: Research and Special Programs Administration (RSPA), DOT.

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.

FOR FURTHER INFORMATION CONTACT: John A. Gale (202) 366-8553, Office of 
Hazardous Materials Standards, or George Cushmac (202) 366-4545, Office 
of Hazardous Materials Technology, RSPA, 400 7th Street, SW, 
Washington, DC 20590. Questions about hazardous substance designations 
or reportable quantities should be directed to the Environmental 
Protection Agency (EPA). Call the RCRA/Superfund hotline at (800) 424-
9346 or, in Washington, DC, (202) 382-3000.

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.
