[Docket No. PHMSA-2006-28711 (HM-145N)]
RIN 2137-AE24

 
Hazardous Materials: Revisions to the List of Hazardous 
Substances and Reportable Quantities

AGENCY: Pipeline and Hazardous Materials Safety Administration (PHMSA), 
DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: PHMSA amends the Hazardous Materials Regulations (HMR) by 
revising the list of hazardous substances and reportable quantities 
(RQs) and by correcting editorial errors to the list of hazardous 
substances and RQs. Superfund (i.e., CERCLA) requires PHMSA to list and 
regulate all hazardous substances designated by the Environmental 
Protection Agency (EPA). This final rule enables shippers and carriers 
to identify the affected hazardous substances, comply with all 
applicable regulatory requirements, and make the required notifications 
if the release of a hazardous substance occurs.

DATES: Effective Date: March 31, 2008.
    Voluntary Compliance Date: PHMSA is authorizing voluntary 
compliance beginning February 29, 2008.

FOR FURTHER INFORMATION CONTACT: Dirk Der Kinderen (202) 366-8553, 
Office of Hazardous Materials Standards, PHMSA, 1200 New Jersey Avenue, 
SE., East Building, Washington, DC 20590-0001. Questions about 
hazardous substance designations or reportable quantities should be 
directed to EPA at the Superfund, EPCRA, RMP and Oil Information 
hotline at (800) 424-9346 or, in Washington, DC, local area (703) 412-
9810.

SUPPLEMENTARY INFORMATION: 

I. Background

    Section 306(a) of the Comprehensive Environmental Response, 
Compensation and Liability Act of 1980 (CERCLA; 42 U.S.C. 9601-9675), 
as amended by section 202 of the Superfund Amendments and 
Reauthorization Act of 1986 (SARA; 42 U.S.C 11011 et seq.), requires 
the Secretary of Transportation to regulate hazardous substances listed 
or designated under Section 101(14) of CERCLA, 42 U.S.C. 9601(14), as 
hazardous materials under the Federal hazardous materials 
transportation law (49 U.S.C. 5101-5128). PHMSA carries

[[Page 1090]]

out the rulemaking responsibilities of the Secretary of Transportation 
under the Federal hazardous materials transportation law, 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 the statutory mandate, PHMSA 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. In accordance with CERCLA 
requirements, EPA must issue final rules amending the list of CERCLA 
hazardous substances, including adjusting RQs, before PHMSA can amend 
the list of hazardous substances in the HMR. PHMSA periodically revises 
the list of hazardous substances and RQs in the HMR (49 CFR Parts 171-
180) as adjustments are made by EPA.
    This final rule revises the ``List of Hazardous Substances and 
Reportable Quantities'' that appears in Table 1 of Appendix A to Sec.  
172.101 to be consistent with EPA's List of Hazardous Substances and 
Reportable Quantities in 40 CFR 302.4 (Table 302.4). The changes made 
in this final rule are based on several EPA final rules that added, 
corrected, or deleted (removed) entries to Table 302.4. In addition, 
this final rule revises the ``List of Hazardous Substances and 
Reportable Quantities'' to correct typographical errors or insert 
inadvertent omissions from previous PHMSA rulemakings that revised the 
list based on previous EPA rule changes.
    This final rule will enable shippers and carriers to identify 
CERCLA hazardous substances, comply with all applicable HMR and EPA 
requirements, and make required notifications if a release of a 
hazardous substance occurs. In addition to the reporting requirements 
of the HMR found in Sec. Sec.  171.15 and 171.16, a release of a 
hazardous substance is subject to EPA notification requirements under 
40 CFR 302.6 and may be subject to the reporting requirements of the 
U.S. Coast Guard under 33 CFR 153.203.

II. Recent Revisions to EPA Table 302.4

    This final rule revises the ``List of Hazardous Substances and 
Reportable Quantities'' that appears in Table 1 of Appendix A to Sec.  
172.101 to be consistent with revisions made in recent EPA rules that 
followed our last reprint of Table 1. The EPA changes to Table 302.4 
are discussed as follows. (See the tables below for a listing of 
hazardous substances added and deleted by the EPA rules discussed 
below.)
    On July 9, 2002, EPA issued a direct final rule (67 FR 45314) 
correcting errors and removing obsolete or redundant language in its 
Table 302.4. The majority of the errors were either typographical or 
the result of inadvertent omissions. Specifically, errors included 
unintentional discrepancies between an individual hazardous substance 
name appearing in Table 302.4 and the same name as it appears in other 
statutes (i.e., Resource Conservation and Recovery Act (RCRA) section 
3001, Clean Water Act (CWA) sections 307 and 311, and Clean Air Act 
(CAA) section 112) and their implementing regulations. EPA made 
corrections to the names of a number of hazardous substances to make 
them consistent with names that appear in these other regulatory lists. 
Many of these corrections are simple and involve, for example, the 
deletion of an unnecessary hyphen or the addition of parentheses. EPA 
added synonyms for six hazardous substances to Table 302.4 to be 
consistent with a February 9, 1995 final rule (60 FR 7824) that added a 
number of synonyms to RCRA regulations for those same substances. The 
hazardous substances and the respective synonyms that were added are 
``Carbaryl; (1-Napthalenol, methylcarbamate)'', ``Carbofuran; (7-
Benzofuranol, 2,3-dihydro-2,2-dimethyl-, methylcarbamate)'', 
``Mercaptodimethur; (Phenol, (3,5-dimethyl-4-(methylthio)-, 
methylcarbamate)'', ``Mexacarbate; (Phenol, 4-(dimethylamino)-3,5-
dimethyl-, methylcarbamate (ester))'', ``Propoxur (Baygon); (Phenol, 2-
(1-methylethoxy)-, methylcarbamate)'', and ``Triethylamine; 
(Ethanamine, N,N-diethyl-).'' EPA also added the entries 
``Bis(chloromethyl) ether'' and ``Bromomethane'' as synonyms to be 
consistent with substances listed in section 112 of the CAA. 
Additionally, EPA removed a number of hazardous substances from Table 
302.4 in the interest of avoiding duplicative entries and deleted a 
number of synonyms of hazardous substances because the synonyms are not 
listed in RCRA, CWA, CAA, or their implementing regulations. Please 
refer to the July 9, 2002 Federal Register noted above for a complete 
explanation of the additions and deletions. This rule revises the 
entries in Table 1 of Appendix A to Sec.  172.101 of the HMR for 
consistency with the revisions in EPA's July 9, 2002 final rule. 
However, we are retaining the entry for ``Methyl chloroformate'' and 
adding the footnote ``@'' because ``Methyl chloroformate'' is also 
listed as a proper shipping name in the Hazardous Materials Table 
(HMT). The footnote ``@'' signifies that the entry is added by PHMSA 
because it is a synonym for a listed hazardous substance and appears in 
the HMT as a proper shipping name.
    On February 24, 2005, EPA issued a final rule (70 FR 9138) that 
added an entry for the K181 waste code (nonwastewaters from the 
production of dyes and/or pigments) to Table 302.4 and assigned the 
waste a statutory one-pound RQ. This rule adds K181 to the ``List of 
Hazardous Substances and Reportable Quantities.''
    On August 16, 2006, EPA issued a final rule (71 FR 47106) that 
adjusted the RQs for 34 hazardous substances from their statutory one-
pound RQs. Specifically, the rule adjusted RQs for 28 individual 
carbamates, five carbamate-related waste codes (K156, K157, K158, K159, 
and K161), and the K178 waste code (inorganic manufacturing process 
waste). With the exception of K156, K157, K158, and K178, these 
materials have not been previously listed in the HMR as hazardous 
substances. This rule adds the 30 previously unlisted hazardous 
substances to the HMR and adjusts the RQs for consistency with EPA 
Table 302.4.
    The following tables identify hazardous substances added or deleted 
in this final rule as well as a Federal Register reference to the EPA 
rule each revision is based upon:

III. PHMSA Revisions Based on Previous EPA Rule Revisions to Table 
302.4

    This final rule also makes corrections to the ``List of Hazardous 
Substances and Reportable Quantities'' appearing in Table 1 of Appendix 
A to Sec.  172.101 to be consistent with revisions made in past EPA 
final rules that pre-date the rules discussed in section II. The 
corrections to the ``List of Hazardous Substances and Reportable 
Quantities'' are explained as follows:
    (1) ``Acetic acid, (2,4,5-trichlorophenoxy)-'' and 
``Carbamodithioic acid, 1,2-ethanediylbis-, salts & esters'' were added 
to EPA Table 302.4 as new names for previously listed hazardous 
substances by a December 27, 1989 EPA final rule (54 FR 53057) but were 
inadvertently not added into the HMR. This rule adds ``Acetic acid, 
(2,4,5-trichlorophenoxy)-'' and ``Carbamodithioic acid, 1,2-
ethanediylbis-, salts & esters'' to the HMR.
    (2) ``Diamine'' and ``1,2,3,4,10-10-Hexachloro-1,4,4a,5,8,8a-
hexahydro-1,4:5,8-endo,exo-dimethanonaphthalene'' were no longer listed 
in Table 302.4 as synonyms for hazardous substances by an August 14, 
1989 EPA final rule (54 FR 33425) but inadvertently remained in the 
HMR. This rule deletes ``Diamine'' and ``1,2,3,4,10-10-Hexachloro-
1,4,4a,5,8,8a-hexahydro-1,4:5,8-endo,exo-dimethanonaphthalene'' from 
the HMR.
    (3) ``3,4-Benzacridine'', ``Carbamide, thio-'', 
``Carbamimidoselenoic acid'', ``Carbon bisulfide``, ``Ethanoyl 
chloride'', ``Ethylenebisdithiocarbamic acid``, ``Methanoic acid'', and 
``Methylene oxide'' were deleted from Table 302.4 as synonyms by a 
December 27, 1989 EPA final rule (54 FR 53057) but inadvertently 
remained in the HMR. This rule deletes the synonyms from the HMR.
    (4) ``Methiocarb'' was added to Table 302.4 as a synonym by a 
February 9, 1995 EPA final rule (60 FR 7824) but was inadvertently not 
added into the HMR. This rule adds ``Methiocarb'' to the HMR.
    (5) ``Aroclors'', ``Chlorinated Camphene'', ``DEHP'', 
``Dibromoethane'', ``Hexone'', ``Iodomethane'', ``Lindane (all 
isomers)'', ``PCBs'', ``PCNB'', ``Quinone'', ``Quintobenzene'', 
``TCDD'', ``2,4-Toluene diamine'', ``2,4-Toluene diisocyanate'', and 
``Urethane'' were added to Table 302.4 as synonyms by a June 12, 1995 
EPA final rule (60 FR 30926) but were inadvertently not added into the 
HMR. This rule adds the synonyms to the HMR.
    (6) ``beta-Propiolactone'' was added as a new entry to Table 302.4 
by a June 12, 1995 EPA final rule (60 FR 30926) but was inadvertently 
not added into the HMR. This rule adds ``beta-Propiolactone'' to the 
HMR.
    (7) The entry for ``1,4-Diethylenedioxide'' was corrected by adding 
``1,4-Diethyleneoxide'' as a synonym to Table 302.4 by July 12, 1995 
Federal Register corrections (60 FR 35991) but ``1,4-Diethyleneoxide'' 
was inadvertently not added into the HMR. This rule adds ``1,4-
Diethyleneoxide'' to the HMR.

IV. PHMSA Changes to Table 1 of Appendix A to Sec.  172.101

    This final rule makes several non-substantive changes to the ``List 
of Hazardous Substances and Reportable Quantities'' that appears in 
Table 1 of Appendix A to Sec.  172.101 of the HMR. Most of the changes 
correct typographical errors (i.e., incorrect RQs) and insert 
inadvertent omissions from

[[Page 1093]]

printings of previous PHMSA rulemakings and the CFR. The changes 
include the removal of descriptive language for waste codes found in 
because it does not also appear in the HMT as a proper shipping name. 
The waste code descriptions are readily available in EPA's List of 
Hazardous Substances and Reportable Quantities in 40 CFR 302.4. In the 
interest of relieving the burden of tracking EPA revisions to waste 
code descriptions for consistency purposes, limiting the potential for 
errors in the text when printing the descriptions, and space savings, 
we believe the waste code descriptions do not need to be duplicated in 
the HMR.
    Several hazardous substances in Table 1 are listed with an 
incorrect RQ and are being corrected by this final rule. The changes 
are discussed as follows:
    (1) The RQ for ``[1,1'-Biphenyl]-4,4'-diamine, 3,3'-dimethoxy-'' 
(and its synonym ``3,3'-Dimethoxybenzidine'') was incorrectly changed 
from 1 to 10 pounds rather than to 100 pounds in the August 21, 1989 
PHMSA final rule (HM-145G; 54 FR 34666). This rule corrects the RQ for 
``[1,1'-Biphenyl]-4,4'-diamine,3,3'-dimethoxy-'' and its synonym to 100 
pounds.
    (2) The RQ for ``Diethylamine'' was incorrectly changed to 1000 in 
the November 7, 1990 PHMSA final rule (HM-145I; 55 FR 46794). This rule 
corrects the RQ for ``Diethylamine'' to 100 pounds.
    (3) The F004 waste code is based on two solvents: ``Cresols/
Cresylic Acid'' and ``Nitrobenzene.'' The August 2, 1995 PHMSA final 
rule (HM-145K; 60 FR 39608) inadvertently revised the RQ for 
``Nitrobenzene'' from 1000 to 100 pounds rather than for ``Cresols/
Cresylic Acid.'' This final rule corrects the RQ for ``Cresols/Cresylic 
Acid'' from 1000 to 100 pounds and the RQ for ``Nitrobenzene'' to 1000 
pounds.
    (4) The RQs for ``Acetic acid, thallium(1+) salt'' and ``1-Acetyl-
2-thiourea'' were incorrectly printed starting with the 1996 edition of 
the CFR. This rule corrects the RQs to 100 and 1000 pounds, 
respectively.
not revised to 10 pounds in the March 5, 2002 PHMSA final rule (HM-
145M; 67 FR 9926). The RQs for synonyms ``Chloromethyl methyl ether'' 
and ``Methane, chloromethoxy-'' were revised without revising the RQ 
    Several hazardous substances were inadvertently omitted from Table 
1. The omissions as well as other corrections to Table 1 are explained 
as follows:
    (1) ``1-Chloro-2,3-epoxypropane'', ``Dimethyl aminoazobenzene'', 
``2,6-Dinitrophenol'', ``2-Methyl aziridine'', and ``m-Nitrophenol'' 
were inadvertently omitted from the HMR through reprintings of the list 
in previous PHMSA rulemakings. This rule returns these entries to the 
HMR.
    (2) The entry for ``DDE'' (and its RQ of 5000 pounds) was 
inadvertently omitted from the HMR starting with the 2000 edition of 
the CFR. This rule returns ``DDE'' and its RQ of 5000 pounds to the 
HMR. In addition, to provide clarification that there should be two 
listings of ``DDE'' with different RQs, CAS numbers are being added to 
the respective ``DDE'' entries. Also, the footnote ``'' is 
added to the end of Table 1 of Appendix A to Sec.  172.101 to provide a 
reference to the EPA rationale for having two entries with different 
RQs for the hazardous substance ``DDE.''
    (3) ``1-Naphthalenamine'' and ``2-Naphthalenamine'' were 
inadvertently omitted from the HMR by including their respective 
synonyms, ``1-Naphthylamine'' and ``2-Naphthylamine'', instead. This 
rule adds ``1-Naphthalenamine'' and ``2-Naphthalenamine'' to the HMR 
and deletes ``1-Naphthylamine'' and ``2-Naphthylamine'' from the HMR.
    Because this rulemaking makes numerous changes to the ``List of 
Hazardous Substances and Reportable Quantities'' found in Table 1 of 
Appendix A to Sec.  172.101, we are reprinting it in its entirety.

V. Regulatory Analyses and Notices

A. 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 
associated with this final rule should be minimal for shippers and 
carriers for several reasons: (1) This rule does not impose new 
requirements on shippers or carriers of hazardous substances, but 
merely lists and makes corrections to hazardous substances already 
subject to regulation by EPA; (2) to the extent that new hazardous 
substances are added to the HMR requiring compliance with regulations 
pertaining to transport of the hazardous substances, most of the new 
entries already meet an existing hazard class definition and are 
currently subject to the HMR. For example, carbamates are widely used 
as ingredients in pesticides. Shippers and carriers would incur some 
increased costs from additional hazard communication requirements 
(e.g., ``RQ'' on shipping papers and marking of packages) but minimal 
compared to costs of compliance with regulations for a hazardous 
substance that previously had not been regulated and; (3) additional 
hazardous substances added into the HMR in this final rule were 
inadvertent omissions or are synonyms of hazardous substances already 
subject to the requirements.
    In consideration of the changes to the RQs for several hazardous 
substances in this rule, we reviewed the ``Economic Impact Analysis 
(EIA) of Proposed Reportable Quantity Adjustments for Carbamates Added 
as RCRA Hazardous Wastes and CERCLA Hazardous Substances, Volume VII,'' 
dated December 2002 prepared by the Environmental Protection Agency 
(EPA) in support of its related final rule. A copy of that document is 
available for review in the EPA docket (EPA-HQ-SFUND-2002-0010-0052).
    According to the EPA EIA, upward RQ adjustments for hazardous 
substances reduce the required telephone notification of releases and 
reduce government and industry time spent on recordkeeping. The effects 
of these actions taken together can be categorized as ``cost savings.'' 
Conversely, downward RQ adjustments would produce increases in these 
same actions and therefore result in additional costs. Likewise, from 
an HMR compliance cost perspective, upward RQ adjustments are expected 
to reduce costs by reducing the number of shipments subject to the 
hazard communication requirements for RQs or subject to the HMR in 
general (by being a hazardous material based solely on being defined as 
a hazardous substance) while downward RQ adjustments are expected to 
increase costs. The majority of the RQ adjustments (based on EPA 
adjustments) in this rule are upwards adjustments leading to an overall 
cost savings.
    This final rule will also enhance transportation safety and 
environmental protection because shippers, carriers, and emergency 
response personnel will be able to identify specific hazardous 
substances and take appropriate actions to comply with the applicable 
packaging and hazard communication requirements and to respond to 
transportation incidents involving hazardous substances.

[[Page 1094]]

B. Executive Order 13132

    This final rule has been analyzed in accordance with the principles 
and criteria contained in Executive Order 13132 (``Federalism''). This 
final rule preempts State, local and Indian tribe requirements but does 
not adopt any regulation that has substantial direct effects on the 
States, the relationship between the national government and the 
States, or the distribution of power and responsibilities among the 
various levels of government. Therefore, the consultation and funding 
requirements of Executive Order 13132 do not apply.
    The Federal hazardous material transportation law, 49 U.S.C. 5101-
5128, contains an express preemption provision (49 U.S.C. 5125(b)) that 
preempts State, local, and Indian tribe requirements on certain covered 
subjects. Covered subjects are:
    (1) The designation, description, and classification of hazardous 
material;
    (2) The packing, repacking, handling, labeling, marking, and 
placarding of hazardous material;
    (3) The preparation, execution, and use of shipping documents 
related to hazardous materials and requirements related to the number, 
contents, and placement of those documents;
    (4) The written notification, recording, and reporting of the 
unintentional release in transportation of hazardous material; or
    (5) The design, manufacture, fabrication, inspection, marking, 
maintenance, reconditioning, repair, or testing of a packaging or 
container represented, marked, certified, or sold as qualified for use 
in transporting hazardous material.
    This final rule addresses covered subject items (1), (2), and (3) 
above and would preempt State, local, and Indian tribe requirements not 
meeting the ``substantively the same'' standard. This rule is required 
by statute. Federal hazardous materials transportation law provides at 
Sec. 5125(b)(2) that, if PHMSA issues a regulation concerning any of 
the covered subjects, PHMSA must determine and publish in the Federal 
Register the effective date of Federal preemption. The 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. 
The effective date of Federal preemption for these requirements is 
April 7, 2008.

C. Executive Order 13175

    This final rule has been analyzed in accordance with the principles 
and criteria contained in Executive Order 13175 (``Consultation and 
Coordination with Indian Tribal Governments''). Because this final rule 
does not have tribal implications, does not impose substantial direct 
compliance costs, and is required by statute, the funding and 
consultation requirements of Executive Order 13175 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. The 
Regulatory Flexibility Act applies only to final rules that are 
preceded by notices of proposed rulemaking (NPRM). Because this rule 
was not preceded by an NPRM, no assessment is required. EPA addressed 
the Regulatory Flexibility Act when it made the hazardous substances 
designation reflected in this rule.

E. Paperwork Reduction Act

    This final rule does not impose any new information collection 
burden.

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 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 final rule imposes no mandates and, thus, does not impose 
unfunded mandates under the Unfunded Mandates Reform Act of 1995. It 
does not result in costs of $120.7 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. Environmental Assessment

    The National Environmental Policy Act of 1969 (NEPA), as amended 
(42 U.S.C. 4321-4347) requires Federal agencies to consider the 
consequences of major Federal actions and prepare a detailed statement 
on actions significantly affecting the quality of the human 
environment.
    Releases of hazardous substances (e.g., carbamates) have the 
potential to cause damage to the human environment. Releases can occur 
during any stage of transportation (i.e., loading, transport, 
unloading, etc.). When a release occurs, it may result in increased 
risk to public health and the environment such as increased human 
exposure to carcinogens or adverse impacts to vegetation and wildlife 
surrounding the location of the release.
    Revisions made to the ``List of Hazardous Substances and Reportable 
Quantities'' found in Table 1 of Appendix A to Sec.  172.101 in this 
final rule enhance environmental protection. Listing of hazardous 
substances in the HMR and the correct RQs promotes better 
identification of these materials, leading to greater compliance with 
the reporting requirements and effective emergency response to 
incidents involving these materials, thereby lessening the potential 
for damage to the human environment. Further, the adjustment of an RQ 
should not have any significant influence on the number of releases 
that occur for that substance. EPA considers inherent substance-
specific risks as part of its RQ adjustment methodology. It is assumed 
that releases of hazardous substances below an (adjusted) RQ, under 
most release circumstances, would not pose a sufficient risk to the 
human environment to warrant a government response. We conclude there 
are no significant environmental impacts associated with this final 
rule.
