Hazardous Substances; Final Rule DEPARTMENT OF TRANSPORTATION

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.
