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. Substances Whose RQ Has Changed ------------------------------------------------------------------------ New RQ/Old Substance RQ (lbs) ------------------------------------------------------------------------ Acetic acid, Lead (2+) salt................................. 10/5000 Lead........................................................ 10/1 Lead acetate................................................ 10/5000 Lead bis (acetatato-0) tetrahydroxytri-..................... 10/100 Lead chloride............................................... 10/100 Lead fluoborate............................................. 10/100 Lead fluoride............................................... 10/100 Lead iodide................................................. 10/100 Lead nitrate................................................ 10/100 Lead phosphate.............................................. 10/1 Lead stearate............................................... 10/5000 Lead subacetate............................................. 10/100 Lead sulfate................................................ 10/100 Lead sulfide................................................ 10/5000 Lead thiocyanate............................................ 10/100 Methane, isocyanato-........................................ 10/1 Methyl isocyanate........................................... 10/1 Phosphoric acid, lead (2+) salt (2:3)....................... 10/1 D008........................................................ 10/1 K002........................................................ 10/1 K003........................................................ 10/1 K005........................................................ 10/100 K046........................................................ 10/100 K048........................................................ 10/1 K049........................................................ 10/1 K051........................................................ 10/1 K061........................................................ 10/1 K062........................................................ 10/1 K064........................................................ 10/1 K065........................................................ 10/1 K066........................................................ 10/1 K069........................................................ 10/1 K086........................................................ 10/1 K100........................................................ 10/1 ------------------------------------------------------------------------ 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.
