I. Background

    The purpose of this NPRM is to update and clarify existing
requirements by incorporating changes into the Hazardous Materials
Regulations (HMR; 49 CFR parts 171-180) based on PHMSA's own
initiatives. The proposed amendments were identified through an
extensive review of the HMR and previously-issued letters of
interpretation to the regulated hazardous materials transportation
community. In addition, this NPRM proposes to incorporate a widely-held
special permit with a longstanding history of safety into the HMR and
respond to a petition for rulemaking. To this end, PHMSA is proposing
to revise, clarify, and relax certain regulatory requirements.
    Specifically, PHMSA is proposing to:
     Permit designated agents for non-residents to submit
designation requests by electronic mail in addition to traditional
mail.
     Add the Sulphur Institute's (TSI) ``Molten Sulphur Rail
Tank Car Guidance'' document to the list of informational materials not
requiring incorporation by reference in Sec.  171.7 (Responds to
petition for rulemaking P-1581).
     Revise the Sec.  172.101 Hazardous Materials Table (HMT)
to correct an error in the transportation requirements for entries
listed under the proper shipping name, ``Hydrazine Dicarbonic Acid
Diazide.''
     Revise the Sec.  172.101 HMT to remove the entry for
``Zinc ethyl, see Diethylzinc'' which was superseded by proper shipping
names adopted in a previous rulemaking.
     Revise special provision 138 in Sec.  172.102 to clarify
the lead solubility calculation utilized for classification of material
as a Marine Pollutant.
     Remove references to special provisions B72 and B74 in
Sec.  172.102. These special provisions were removed in a previous
rulemaking; however, twelve entries in the Sec.  172.101 HMT still
contain references to these special provisions.
     Revise the shipping paper requirements in Sec.  172.203(e)
to permit the phrase ``Residue last contained'' to be placed before or
after the basic shipping description sequence, or for rail shipments,
directly preceding the proper shipping name in the basic shipping
description sequence.
     Update the training recordkeeping requirements in Sec.
172.704 to specify that a hazardous materials (hazmat) employer must
make hazmat employee training records available upon request, at a
reasonable time and location, to an authorized official of the
Department of Transportation or the Department of Homeland Security.
     Clarify that the material of trade exception in Sec.
173.6 may be used when transporting Division 2.1 and 2.2 gases in Dewar
flasks.
     Clarify the lab pack provisions in Sec.  173.12 pertaining
to temperature-controlled materials contained in a lab pack.
     Clarify the exceptions for external emergency self-closing
valves on cargo tank motor vehicles (CTMVs) in Sec.  173.33(g) to
specify that external emergency self-closing valves on MC 338 cargo
tanks containing cryogenic liquids may remain open during
transportation.
     Correct an inadvertent deletion of the Sec.  173.62
packaging requirements for explosives.
     Incorporate special permit DOT SP-13556 into Sec.
173.134, to authorize the transportation by motor vehicle of certain
regulated medical wastes, designated as sharps, in non-DOT
specification containers fitted into wheeled racks.
     Revise the requirements for cargo air transport of
alcoholic beverages Sec.  173.150 to harmonize with the International
Civil Aviation Organization's (ICAO) Technical Instructions (TI).
     Clarify the exceptions in Sec.  173.159a for non-spillable
batteries secured to skids or pallets.
     Revise Sec.  178.2(c) to clarify the applicability of the
notification requirements for packages containing residues.
     Clarify the inspection record requirements in Sec.
180.416 for discharge systems of cargo tanks transporting liquefied
compressed gases.
     Clarify the requirements for the Flame Penetration
Resistance test required for chemical oxygen generators and certain
compressed gases in Appendix E to Part 178.

II. Section-by-Section Review

Part 105

Section 105.40
    This section provides the requirements for designated agents for
non-residents. In specific instances, such as the approval of fireworks
manufactured by a foreign entity, the HMR require non-residents of the
United States who perform hazmat operations within the United States to
designate a permanent resident of the United States to act as an agent
and receive documents on behalf of the non-

resident. As specified in the HMR, non-residents of the United States
must prepare a designation notification and file it with PHMSA in
accordance with Sec.  105.40.
    Currently, the HMR only permits designated agent notification
documents to be mailed to the Approvals and Permits Division, Pipeline
and Hazardous Materials Safety Administration, Attn: PHH-30, U.S.
Department of Transportation, East Building, 1200 New Jersey Avenue
SE., Washington, DC 20590-0001, as specified in Sec.  105.40(d).
Revising this requirement to allow an agent designation to be
transmitted by electronic mail would provide greater regulatory
flexibility and align the submission of these documents with the
procedures currently in place for the submission of other documents
required by PHMSA.
    In this NPRM, PHMSA is proposing to amend Sec.  105.40(d) to permit
agent designations to be submitted by electronic mail to the special
permits or approvals office, as appropriate. The option to submit a
completed agent designation to the Approvals and Permits Division by
mail would remain unchanged.

Part 171

Section 171.7
    The National Technology Transfer and Advancement Act of 1995 (15
U.S.C. 272) directs agencies to use voluntary consensus standards in
lieu of government-unique standards except where inconsistent with law
or otherwise impractical. Section 171.7 lists all standards
incorporated by reference into the HMR and informational materials not
requiring incorporation by reference. The informational materials not
requiring incorporation by reference are noted throughout the HMR and
provide best practices and additional safety measures that while not
mandatory, may enhance safety and compliance.
    The Sulphur Institute (TSI) represents the sulphur industry in the
United States on a variety of issues including the safe transportation
of sulphur in commerce. TSI submitted petition P-1581 requesting that
PHMSA incorporate by reference TSI's ``Molten Sulphur Tank Rail Car
Guidance Document.'' TSI also requested that we amend Sec.
173.24(b)(4) to add the sentence ``Dried residue of molten sulfur on
tank cars shall meet the `Molten Sulphur Rail Car Guidance Document'
incorporated by reference in Sec.  171.7.'' TSI recognizes that molten
sulphur rail tank cars with formed, solid sulphur obscuring tank car
markings, labels, and stencils can present a safety risk. Furthermore,
markings and labels with diminished visibility due to molten sulphur
residue present an obstacle to not only those responsible for the safe
handling of these rail tank cars, but also to first responders who rely
on rapid and accurate identification of a material through hazard
communication markings in the event of an accident or incident.
Further, the presence of an excessive amount of formed, solid sulphur
on molten sulphur tank car safety appliances may also lead to decreased
effectiveness of safety equipment. To address these issues, TSI has
created a document entitled ``Molten Sulphur Rail Tank Car Guidance''
which provides best practices for the safe transport of molten sulphur
in rail tank cars.
    In this rulemaking, PHMSA proposes to adopt ``Molten Sulphur Rail
Tank Car Guidance'' in the list of informational materials not
requiring incorporation by reference in Sec.  171.7(b). The inclusion
of this document as reference material in the HMR should provide rail
shippers of molten sulfur with a greater situational awareness of safe
transport conditions for this particular commodity and reduce rail
incidents for this hazardous material. In addition, PHMSA proposes to
revise the entries for ``Sulfur, Molten'' specified in the Sec.
172.101 HMT to reference special provision ``R1'' and add special
provision ``R1'' to the R codes specified in Sec.  172.102(c)(6). This
new special provision will recommend the use of the Molten Sulphur Rail
Tank Car Guidance document when transporting ``Sulfur, Molten''
residues by rail; however, it will not make its use mandatory. By
referencing this document, we believe a greater level of safety may be
achieved during the transportation of rail tanks cars which have held
or currently hold molten sulfur.

Part 172

Section 172.101
    This section contains the HMT and explanatory text for each of the
columns in the table. In this NPRM, PHMSA is proposing a number of
revisions to the Sec.  172.101 HMT, and the special provisions
specified in Sec.  172.102 to clarify the regulations and correct
inadvertent errors. Proposed changes to the Sec.  172.101 HMT will
appear as an, ``add,'' ``remove,'' or ``revise,'' and include the
following:
     Hydrazine dicarbonic acid diazide
     Zinc ethyl, see Diethylzinc
     Hydrazine dicarbonic acid diazide
     UN3469 Paint related material, flammable, corrosive
(including paint thinning or reducing compound)
     UN2484 tert-Butyl isocyanate
     NA2927 Ethyl phosphonothioic dichloride, anhydrous
     NA2845 Ethyl phosphonous dichloride, anhydrous pyrophoric
liquid
     NA2927 Ethyl phosphorodichloridate
     NA2845 Methyl phosphonous dichloride, pyrophoric liquid
     UN1831 Sulfuric acid, fuming with 30 percent or more free
sulfur trioxide
     NA2448 Sulfur, molten
     UN2448 Sulfur, molten
     UN3492 Toxic by inhalation liquid, corrosive, flammable,
n.o.s. with an inhalation toxicity lower than or equal to 200 ml/m3 and
saturated vapor concentration greater than or equal to 500 LC50
     UN3493 Toxic by inhalation liquid, corrosive, flammable,
n.o.s. with an inhalation toxicity lower than or equal to 1000 ml/m\3\
and saturated vapor concentration greater than or equal to 10 LC50
     UN3488 Toxic by inhalation liquid, flammable, corrosive,
n.o.s. with an inhalation toxicity lower than or equal to 200 ml/m\3\
and saturated vapor concentration greater than or equal to 500 LC50
     UN3489 Toxic by inhalation liquid, flammable, corrosive,
n.o.s. with an inhalation toxicity lower than or equal to 1000 ml/m\3\
and saturated vapor concentration greater than or equal to 10 LC50
     UN3490 Toxic by inhalation liquid, water-reactive,
flammable, n.o.s. with an inhalation toxicity lower than or equal to
200 ml/m\3\ and saturated vapor concentration greater than or equal to
500 LC50
     UN3491 Toxic by inhalation liquid, water-reactive,
flammable, n.o.s. with an inhalation toxicity lower than or equal to
1000 ml/m\3\ and saturated vapor concentration greater than or equal to
10 LC50
    On January 28, 2008, PHMSA published a final rule under Docket
Number PHMSA-2005-21812 (HM-218D) [73 FR 4699] entitled ``Hazardous
Materials; Miscellaneous Amendments.'' In this final rule, one of the
two duplicate entries in the Sec.  172.101 HMT for ``Hydrazine, aqueous
solution, with more than 37% hydrazine, by mass'' was intended to be
eliminated. Although one entry in the Sec.  172.101 HMT for
``Hydrazine, aqueous solution, with more than 37% hydrazine, by mass''
was deleted, during the table revisions of this final rule, Columns 5
through 10 for the

entries for ``Hydrazine, aqueous solution, with more than 37%
Hydrazine, by mass'' Packing Groups II and III were inadvertently
relocated below the entry ``Hydrazine dicarbonic acid diazide.''
``Hydrazine dicarbonic acid diazide'' should not have any entries in
Columns 5 through 10 as it is forbidden for transport in the HMR. The
appearance of these entries in the Sec.  172.101 HMT is confusing and
could potentially lead to the mistaken belief that ``Hydrazine
dicarbonic acid diazide'' is not a forbidden material, but, rather
authorized for transport as a Packing Group II or III material.
Therefore, in this NPRM, we are proposing to remove the Packing Group
II and III entries for the proper shipping name, ``Hydrazine dicarbonic
acid diazide'' in the Sec.  172.101 HMT.
    On January 14, 2009, PHMSA published a final rule under Docket
Numbers PHMSA-2007-0065 (HM-224D) and PHMSA-2008-0005 (HM-215J) [74 FR
220] entitled ``Hazardous Materials: Revision to Requirements for the
Transportation of Batteries and Battery-Powered Devices; and
Harmonization with the United Nations Recommendations, International
Maritime Dangerous Goods Code, and International Civil Aviation
Organization's Technical Instructions.'' Among other revisions, PHMSA
removed various specific entries for organometallic compounds and
substances in the Sec.  172.101 HMT because these entries were
superseded by more appropriate generic entries. As part of these
revisions, the entry for ``UN1366 Diethylzinc'' was removed from the
Sec.  172.101 HMT. However, the entry for ``Zinc ethyl, see
Diethylzinc'' was inadvertently overlooked.
    In this NPRM, we are proposing to remove the proper shipping name,
``Zinc ethyl, see Diethylzinc'' since ``UN1366 Diethylzinc'' is no
longer listed in the Sec.  172.101 HMT. Individuals offering ``Zinc
ethyl'' should choose one of the more appropriate generic entries for
organometallic compounds and substances added to the Sec.  172.101 HMT
under the January 14, 2009 final rule.
    On January 13, 2009, PHMSA, in coordination with the Federal
Railroad Administration (FRA), published a final rule under Docket
Number FRA-2006-25169 [74 FR 1770], entitled ``Hazardous Materials:
Improving the Safety of Railroad Tank Car Transportation of Hazardous
Materials.'' Among other revisions, this final rule revised the HMR to
improve the crashworthiness protection of railroad tank cars designed
to transport poisonous inhalation hazard (PIH) materials. As part of
this final rule, the Sec.  172.101 HMT and special provisions specified
in Sec.  172.102 were amended to consolidate and update the special
provisions applicable to the rail tank car transportation of PIH
materials. The revisions to the Sec.  172.101 HMT were for ease of
reference only and did not substantively change the requirements
applicable to the transportation of PIH materials by railroad tank
cars. Specifically, special provisions B71, B72, and B74 were removed
from the Sec.  172.101 HMT and Sec.  172.102, while Sec.  172.244(a)
was revised to incorporate the language from these eliminated special
provisions. However, twelve additional references to special provisions
B72, and B74 for selected entries in the Sec.  172.101 HMT were not
removed at the time of publication of this final rule. Therefore, in
this NPRM, PHMSA proposes to make the following amendments to the
Column (7) special provisions of the Sec.  172.101 HMT:
    Special provision B72 is removed from Column (7) for the following
entries:
    UN2484 tert-Butyl isocyanate;
    UN3492 Toxic by inhalation liquid, corrosive, flammable, n.o.s.
with an inhalation toxicity lower than or equal to 200 ml/m\3\ and
saturated vapor concentration greater than or equal to 500 LC50;
    UN3488 Toxic by inhalation liquid, flammable, corrosive, n.o.s.
with an inhalation toxicity lower than or equal to 200 ml/m\3\ and
saturated vapor concentration greater than or equal to 500 LC50; and
    UN3490 Toxic by inhalation liquid, water-reactive, flammable,
n.o.s. with an inhalation toxicity lower than or equal to 200 ml/m\3\
and saturated vapor concentration greater than or equal to 500 LC50.
    Special provision B74 is removed from Column (7) for the following
entries:
    NA2927 Ethyl phosphonothioic dichloride, anhydrous;
    NA2845 Ethyl phosphonous dichloride, anhydrous pyrophoric liquid;
    NA2927 Ethyl phosphorodichloridate;
    NA2845 Methyl phosphonous dichloride, pyrophoric liquid;
    UN1831 Sulfuric acid, fuming with 30 percent or more free sulfur
trioxide;
    UN3493 Toxic by inhalation liquid, corrosive, flammable, n.o.s.
with an inhalation toxicity lower than or equal to 1000 ml/m\3\ and
saturated vapor concentration greater than or equal to 10 LC50;
    UN3489 Toxic by inhalation liquid, flammable, corrosive, n.o.s.
with an inhalation toxicity lower than or equal to 1000 ml/m\3\ and
saturated vapor concentration greater than or equal to 10 LC50; and
    UN3491 Toxic by inhalation liquid, water-reactive, flammable,
n.o.s. with an inhalation toxicity lower than or equal to 1000 ml/m\3\
and saturated vapor concentration greater than or equal to 10 LC50.
    In addition, as discussed above, PHMSA proposes to revise the
entries for ``Sulfur, Molten'' specified in the Sec.  172.101 HMT to
reference special provision ``R1.''
Section 172.102
    This section contains the special provisions listed in column (7)
of the Sec.  172.101 HMT. These special provisions contain packaging
provisions, prohibitions, exceptions from requirements for particular
quantities or forms of materials, and requirements or prohibitions
applicable to specific modes of transportation. In this NPRM, PHMSA is
proposing revisions to the special provisions specified in Sec.
172.102 to clarify the regulations and correct inadvertent errors.
    As discussed above, PHMSA proposes to add special provision ``R1''
to the R codes specified in Sec.  172.102(c)(6). This new special
provision will reference the ``Molten Sulphur Rail Tank Car Guidance''
document as a resource for best practices for the cleaning of tank cars
containing ``Sulfur, Molten.'' By referencing this document, we believe
a greater level of safety can be achieved when transporting rail tanks
cars which have held or currently hold molten sulfur.
    In this rulemaking, we propose to revise special provision 138 to
harmonize the HMR with the International Maritime Dangerous Goods
(IMDG) code and to clarify that the solubility calculation provided in
special provision 138 should be applied when determining when to
utilize the lead compounds, soluble n.o.s. entry in the List of Marine
Pollutants found in Sec.  172.101, Appendix B.
    The defining criteria for the solubility of a lead compound is
specified in special provision 138 in Sec.  172.102(c)(1). Special
provision 138 specifies that a lead compound is soluble when it
exhibits a solubility greater than 5 percent after being mixed with a
0.07 M (molar concentration) of hydrochloric acid and is stirred for
one hour. If the material exhibits a solubility of 5 percent or less
after the test is completed, it is considered insoluble and not subject
to the HMR. The IMDG Code identifies ``Lead compounds, soluble,
n.o.s.,'' in Columns 4 and 6 of

the Dangerous Goods List (DGL; Chapter 3.2) as a marine pollutant, and
simultaneously refers to the definition for the solubility of lead
compounds under Chapter 3.3.1, special provision 199.
    On March 5, 1999, the Research and Special Programs Administration
(RSPA), the predecessor agency to PHMSA, published a final rule under
Docket Number RSPA-98-4185 (HM-215C) [64 FR 10741], entitled
``Harmonization with the United Nations Recommendations, International
Maritime Dangerous Goods Code, and International Civil Aviation
Organization's Technical Instructions.'' In HM-215C, when PHMSA
incorporated the IMDG code's definition for ``Lead compounds, soluble,
n.o.s.,'' in special provision 138 into the HMR, our intent was to
mirror special provision 199 of the IMDG code and to permit the
definition provided in this special provision to apply to both the
``lead compounds, soluble n.o.s.'' entry in the Sec.  172.101 HMT and
the entry in the List of marine pollutants in Sec.  172.101, Appendix
B. However, as adopted in the HMR, special provision 138 is unclear
with regard to whether this criteria applies to marine pollutants.
    On December 29, 2006, PHMSA published a final rule under Docket
Number PHMSA-2006-25476 (HM-215I) [71 FR 78596], entitled
``Harmonization with the United Nations Recommendations, International
Maritime Dangerous Goods Code, and International Civil Aviation
Organization's Technical Instructions.'' The HM-215I final rule revised
the HMR to maintain alignment with international standards by
incorporating various amendments, including changes to proper shipping
names, hazard classes, packing groups, special provisions, packaging
authorizations, air transport quantity limitations, and vessel stowage
requirements. These revisions also harmonized the HMR with certain
changes to the IMDG Code, the ICAO Technical Instructions, and the
United Nations (UN) Recommendations. As part of the revisions in that
final rule, new entries, ``UN3469, Paint related material, flammable,
corrosive (including paint thinning or reducing compound),'' PG II, and
PG III were added to the Sec.  172.101 HMT. However, these entries were
never published in subsequent versions of the HMR. Therefore, in this
NPRM, we are proposing to add the entries for ``Paint related material,
flammable, corrosive (including paint thinning or reducing compound)''
UN3469, PG II, and PG III.
Section 172.203
    Section 172.202 specifies the requirements that a shipping
description of a hazardous material must be indicated on a shipping
paper. On December 29, 2006, PHMSA published a final rule under PHMSA-
06-25476 (HM-215I) [71 FR 78595] that permitted the continued use for
domestic shipments of either one of two shipping description sequences
in effect in the HMR on December 31, 2006, until January 1, 2013.
Specifically, the HMR authorizes the basic description of a hazardous
material to consist of either the identification number first, followed
by the proper shipping name, hazard class, and packing group, or as an
alternative description sequence, the proper shipping name, hazard
class, ID number and packing group. In addition, the basic description
described above and specified in paragraphs Sec.  172.202(a)(1)-(4)
must be shown in the sequences described with no additional information
interspersed. After January 1, 2013, only the basic shipping
description sequence consisting of the identification number first,
followed by the proper shipping name, hazard class, and packing group
(in that order) is authorized.
    However, Sec.  172.203 provides allowances for a shipping paper to
contain information in addition to the basic shipping description
specified in Sec.  172.202. Specifically, Sec.  172.203(e)(1) permits
that the shipping paper for a packaging containing the residue of a
hazardous material may include the words ``RESIDUE: LAST CONTAINED * *
*'' in association with the basic description of the hazardous material
last contained in the packaging. Further, the shipping papers for tank
cars containing the residue of a hazardous material must include the
phrase, ``RESIDUE: LAST CONTAINED * * *'' before the basic description.
While the HMR provides such a general provision, various international
standards provide more specific guidance on the location of this
phrase. Currently the ICAO TI, IMDG Code, and UN Model Regulations
require this phrase, if used, to be placed either before or after the
basic shipping description.
    In this NPRM, PHMSA proposes to revise Sec.  172.203(e)(1) to
permit the shipping paper for a packaging containing the residue of a
hazardous material to include the words ``RESIDUE: LAST CONTAINED * *
*'' before or after the basic shipping description of the hazardous
material last contained in the packaging. PHMSA also proposes to remove
the language ``in association with'' and replace it with the language
``before or after'' to align with various international standards. This
proposed revision harmonizes the HMR with the ICAO TI, IMDG Code and UN
Model Regulations.
    For rail shipments of tank cars, Sec.  172.203(e)(2) requires that
the description on the shipping paper for a tank car containing the
residue of a hazardous material must include the phrase, ``RESIDUE:
LAST CONTAINED * * *'' before the basic description. Prior to the
publication of the HM-215I final rule, the proper shipping name was the
first piece of information required in the basic shipping description,
and therefore, the phrase, ``RESIDUE: LAST CONTAINED * * *'' preceded
the proper shipping name.
    Effective January 1, 2013, rail shipments coming from Canada to the
United States will be unable to comply with both the current
requirements in the HMR for rail tank cars and the Transportation of
Dangerous Goods (TDG) requirements. As stated above, after January 1,
2013, the proper shipping name will no longer be permitted to be the
first piece of shipping information in the basic shipping description.
Subsequently, the phrase, ``RESIDUE: LAST CONTAINED * * *'' will no
longer immediately precede the proper shipping name. Furthermore the
phrase, ``RESIDUE: LAST CONTAINED * * *'' may not be inserted into the
basic description, as Sec.  172.202(b) specifies the basic shipping
description may not contain any additional information interspersed in
the sequence described in Sec.  172.202(a). Canada's TDG regulations
currently permit a residue of hazardous material to be described as
``Residue--Last Contained'' or ``R[eacute]sidu--dernier contenu,''
followed by the shipping name of the dangerous goods last contained in
the means of containment.
    Therefore, in this NPRM, PHMSA proposes to revise Sec.
172.203(e)(2) to require the description on the shipping paper for a
tank car containing the residue of a hazardous material to include the
phrase, ``RESIDUE: LAST CONTAINED * * *'' before or after the basic
shipping description, or immediately preceding the proper shipping
name. This change maintains the HMR's harmonization with the ICAO TI,
IMDG Code and UN Model Regulations while permitting shipments
transported to, from or within the United States to remain in
compliance with the Canadian TDG shipping paper requirements. This
revision will foster commerce between rail systems in the United States
and Canada.

Section 172.704
    The requirements for hazardous materials training are specified in
Sec.  172.704. This section includes a description of the applicability
for hazardous materials training, the necessary components of a
training program, and the recurrent training and recordkeeping
requirements.
    Currently, 49 CFR Part 172, Subpart I describes the requirements
for security plans. Specifically, Sec. Sec.  172.802(d) and
172.820(i)(1) require that a copy of the security plan must be
maintained and that security plan documentation be made available upon
request, at a reasonable time and location, to an authorized official
of the Department of Transportation (DOT) or the Department of Homeland
Security (DHS).
    Similar to the security plan requirements, the training
requirements include a recordkeeping component. Specifically, as
specified in Sec.  172.704(d), a record of current training, inclusive
of the preceding three years, must be created and retained by each
hazmat employer for as long as that employee is employed by that
employer as a hazmat employee and for 90 days thereafter. However,
unlike the security plan documentation, the HMR currently do not
stipulate that the training records must be made available upon request
to authorized officials of the DOT or DHS.
    The Federal hazardous materials transportation law (Federal hazmat
law, 49 U.S.C. 5101 et seq.) authorizes the Secretary of Transportation
to prescribe regulations for the safe transportation of hazardous
material in intrastate, interstate, and foreign commerce. The Secretary
has delegated this authority to PHMSA. Authority to enforce the HMR has
been delegated to the Federal Aviation Administration ``with particular
emphasis on the transportation or shipment of hazardous materials by
air;'' the Federal Railroad Administration ``with particular emphasis
on the transportation or shipment of hazardous materials by railroad;''
PHMSA ``with particular emphasis on the shipment of hazardous materials
and the manufacture, fabrication, marking, maintenance, reconditioning,
repair or test of multi-modal containers that are represented, marked,
certified, or sold for use in the transportation of hazardous
materials;'' and the Federal Motor Carrier Safety Administration ``with
particular emphasis on the transportation or shipment of hazardous
materials by highway'' (CFR part 1, subpart C). In addition, as
provided in the Homeland Security Act and as defined in a Memorandum of
Agreement between the DHS and the DOT, the United States Coast Guard
retained the ability to enforce the HMR with particular emphasis on the
transportation or shipment of hazardous materials by vessel. Thus,
enforcement of the HMR, including the training regulations, is shared
among the DOT operating administrations, United States Coast Guard and
DHS, with each placing particular emphasis on their respective
authorities.
    Federal hazmat law, 49 U.S.C. 5121(b)(2), states that a person
subject to this law shall make the records, property, reports, and
information available for inspection when the Secretary undertakes an
investigation or makes a request. The completion of training in
accordance with Subpart H of Part 172 is essential for hazmat employees
handling hazardous materials and ensures proper compliance with the HMR
resulting in a greater level of safety. The recordkeeping requirements
specified in Sec.  172.704(d) allow for hazmat employers and PHMSA
personnel to verify that only individuals knowledgeable in the
applicable regulations are handling hazardous materials.
    In an effort to foster greater compliance with the training
requirements specified in Subpart H of Part 172, in this rulemaking we
are proposing to revise Sec.  172.704(d) to require that an employer
must make hazmat employee training records required by Subpart H of
Part 172 available upon request, at a reasonable time and location, to
an authorized official of DOT or DHS.

Part 173

Section 173.6
    Section 173.6 specifies the exceptions for shipments of materials
of trade. A material of trade, is defined in Sec.  171.8 as ``a
hazardous material, other than a hazardous waste, that is carried on a
motor vehicle for the purpose of protecting the health and safety of
the motor vehicle operator or passengers; for the purpose of supporting
the operation or maintenance of a motor vehicle (including its
auxiliary equipment); or by a private motor carrier (including vehicles
operated by a rail carrier) in direct support of a principal business
that is other than transportation by motor vehicle.'' Section 173.6
authorizes only specific hazard classes and quantities to utilize the
materials of trade exception. A hazardous material that meets the
definition of a material of trade and is transported by motor vehicle
in conformance with Sec.  173.6 is not subject to any other
requirements of the HMR except for those explicitly set forth or
referenced in Sec.  173.6.
    PHMSA recently received a request for a formal letter of
interpretation pertaining to the application of the materials of trade
exception (Reference No.: 10-0101). The letter expressed confusion and
concern regarding whether the exception would apply to Division 2.1 and
Division 2.2 compressed gas transported in Dewar flasks. Dewar flasks
are not considered cylinders but are often used to transport Division
2.2 cryogenic liquids. Currently, Sec.  173.6(a)(2) states that a
Division 2.1 or 2.2 material in a cylinder with a gross weight not over
100 kg (220 pounds), may be transported as a material of trade provided
it meets the definition of a material of trade specified in Sec.  171.8
and all other requirements of Sec.  173.6. As noted in PHMSA's response
to this letter, Dewar flasks are permitted to utilize the exception
specified in Sec.  173.6 provided they meet all the requirements of
that section. PHMSA did not intend to limit the materials of trade
exception solely to Division 2.1 or 2.2 materials packaged in
cylinders.
    PHMSA acknowledges that this requirement needs additional
clarification, and believes that increased clarity will help to ensure
the proper intended application of the materials of trade exception.
Therefore, in this NPRM, we are proposing to modify Sec.  173.6(a)(2)
to clarify that Dewar flasks may be transported as materials of trade
provided these materials meet all the requirements specified in Sec.
173.6.
Section 173.12
    Section 173.12 specifies the exceptions for shipment of waste
materials including the requirements for waste packages known as ``lab
packs.'' A lab pack, although not specifically defined in Sec.  171.8,
is considered a large outer packaging containing small inner packagings
that are filled with various compatible laboratory hazardous wastes. In
accordance with Sec.  173.12, a lab pack is a combination packaging
consisting of a glass inner packaging, not exceeding 4 L (1 gallon)
rated capacity, or a metal or plastic inner packaging, not exceeding 20
L (5.3 gallons) rated capacity. Inner packagings containing liquid must
be surrounded by a chemically-compatible absorbent material in
sufficient quantity to absorb the total liquid contents. These inner
packagings are then further packed in specification outer packaging and
the completed package must not exceed a gross weight of 205 kilograms.
The requirements and regulatory relief

provided for the transportation of waste hazardous materials under the
lab pack exception are specified in Sec.  173.12(b) of the HMR.
    The requirements for lab packs were adopted in a final rule
published under Docket Number HM-181 entitled, ``Performance Oriented
Packaging Standards; Changes to Classification, Hazard Communication,
Packaging and Handling Requirements Based on UN Standards and Agency
Initiative'' and published on December 21, 1990 [55 FR 52402]. These
requirements were adopted to align the HMR with regulations on lab
packs issued by the Environmental Protection Agency.
    The lab packing section was recently amended in a final rule
published on May 14, 2010, in the Federal Register under Docket Number
PHMSA-2009-0289 (HM-233A) [74 FR 53413] entitled, ``Hazardous
Materials: Incorporation of Special Permits into Regulations.'' As part
of these amendments, certain widely-used and longstanding special
permits that had an established safety record were incorporated into
the HMR. Special Permit DOT SP-13192 was among these special permits,
and it authorized the transport of additional hazardous materials not
previously authorized for transport under Sec.  173.12. Specifically,
the incorporation of this special permit authorized the transport of
waste Division 4.2, Packing Group (PG) I material and Division 5.2
(organic peroxide) material in lab packs.
    PHMSA recently received a request for a formal letter of
interpretation pertaining to the recent changes of the lab pack
exception (Reference No.: 10-0233). The writer expressed confusion and
concern regarding whether the amendments of the HM-233A final rule
authorized the transportation, as lab packs, of Division 4.1 and
Division 5.2 materials that were also required to be temperature-
controlled. PHMSA explained that Sec.  173.12(b) permits certain waste
materials to be placed in non-specification packagings which conform to
the requirements of that section. Furthermore, hazardous materials
placed in lab packs are also subject to additional safety control
measures designed to mitigate the risks presented by these materials,
such as quantity limitations, additional packaging, and segregation
requirements. However, these control measures do not eliminate the
requirement that lab packs containing materials required to be
temperature-controlled must also comply with temperature-control
requirements specified in Sec.  173.21(f)(1).
    PHMSA acknowledges that this requirement needs additional
clarification, and believes that increased clarity will help to ensure
that individuals transporting lab packs containing temperature-
controlled materials are aware that such packagings are not excepted
from other safety measures. Therefore, in this NPRM, we are proposing
to modify Sec.  173.12 to clarify that temperature-controlled materials
may be transported in lab packs provided these materials also meet the
requirements in Sec.  173.21(f)(1).
Section 173.33
    Section 173.33 provides the requirements for hazardous materials
transported in Cargo Tank Motor Vehicles (CTMVs). This section includes
general requirements for CTMVs, as well as more specific requirements
for loading, maximum lading pressure, relief systems, and closing
valves.
    Section 173.33(g) requires each liquid filling and liquid discharge
line in a specification MC 338 cargo tank must be provided with a
remotely-controlled internal self-closing stop valve except when the MC
338 cargo tank is used to transport argon, carbon dioxide, helium,
krypton, neon, nitrogen, and xenon.
    The discharge control device requirements for a MC 338 cargo tank
are found in Sec.  178.338-11(b) and state that each liquid filling and
liquid discharge line must be provided with a shut-off valve located as
close to the tank as practicable and, unless the valve is manually
operable at the valve, the line must also have a manual shut-off valve.
    PHMSA received a request for a formal letter of interpretation
regarding the current requirements for MC 338 cargo tanks (Reference
No.: 06-0243). According to the request, most vacuum insulated MC 338
cargo tanks operate at temperatures below the reliable operating
temperature of available internal self-closing stop valves, and
currently no manufacturer builds an internal self-closing stop valve
that will operate reliably at temperatures that may reach minus
452[emsp14] [deg]F. The requestor asked if a MC 338 cargo tank is
required to have a remotely-controlled internal self-closing stop valve
as specified in Sec.  173.33(g), provided an external stop valve is
present in accordance with Sec.  178.338-11(b).
    PHMSA does not intend to require a remotely-controlled internal
self-closing stop valve if the MC 338 cargo tank already utilizes an
external self-closing stop valve to meet the requirements in Sec.
178.338-11(b). Therefore, in this rulemaking, we are proposing to
revise the provisions in Sec.  173.33(g) to clarify this exception.
Section 173.62
    Section 173.62 specifies packaging requirements for explosives.
Specifically, Sec.  173.62 provides a table that specifies the
packaging instructions, and corresponding authorized inner,
intermediate and outer packagings based on the assigned identification
number of the explosive.
    In a final rule published on September 13, 2011, under Docket
Number PHMSA-2011-0134 (HM-244D) [76 FR 56304], entitled ``Minor
Editorial Corrections and Clarifications,'' PHMSA revised Sec.
173.63(c)(5) packaging instruction 130 to authorize the use of aluminum
boxes (4B) and natural wood, sift-proof walls boxes (4C2). However, the
following language was inadvertently removed from the first column of
the packing instruction:

    2. Subject to approval by the Associate Administrator, large
explosive articles, as part of their operational safety and
suitability tests, subjected to testing that meets the intentions of
Test Series 4 of the UN Manual of Tests and Criteria with successful
test results, may be offered for transportation in accordance with
the requirements of this subchapter.''

    PHMSA did not intend to remove this portion of the packaging
instruction and unnecessarily limit the transport of large explosive
articles. Therefore, in this NPRM, PHMSA is proposing to revise Sec.
173.63(c)(5) packing instruction 130 to reinstate the language
inadvertently removed from the first column of packing instruction 130.
Section 173.134
    Section 173.134 provides definitions and exceptions for infectious
substances. Paragraph (c)(2) of this section requires a Regulated
Medical Waste (RMW) that contains Category B cultures and stocks to be
transported on a vehicle ``used exclusively'' to transport RMW. A
Category B substance is defined as ``an infectious substance that is
not in a form generally capable of causing permanent disability or
life-threatening or fatal disease in otherwise healthy humans or
animals when exposure to it occurs.''
    As amended on July 20, 2011, in a final rule published under Docket
Number PHMSA-2009-0151 (HM-218F) [76 FR 43510], entitled
``Miscellaneous Amendments,'' PHMSA revised Sec.  173.134(c)(2) to
incorporate the clarifications from a March 19, 2007 letter of
interpretation (Ref. No. 07- 0057). Specifically, PHMSA specified that
the following materials may be

transported on a vehicle used exclusively to transport RMW: (1) Plant
and animal waste regulated by the Animal and Plant Health Inspection
Service (APHIS); (2) waste pharmaceutical materials; (3) laboratory and
recyclable wastes; (4) infectious substances that have been treated to
eliminate or neutralize pathogens; (5) forensic materials being
transported for final destruction; (6) rejected or recalled health care
products; and (7) documents intended for destruction in accordance with
Health Insurance Portability and Accountability Act of 1996 (HIPAA)
requirements.
    In response to the proposals in the HM-218F Notice of Proposed
Rulemaking, Stericycle commented that the rationale underlying PHMSA's
decision to authorize the transportation of multiple waste streams from
medical facilities should also apply to other regulated activities,
specifically to those covered under special permit DOT SP-13556, which
authorizes the transportation of sharps in specialized containers. At
the time of the July 20, 2011 final rule, PHMSA determined that
incorporating special permit DOT SP- 13556 into the HMR was beyond the
scope of that rulemaking, but this issue would be addressed in a future
NPRM. We are addressing the issue in this rulemaking. Therefore, in
this NPRM, PHMSA is proposing to revise Sec.  173.134(c)(2) to
incorporate special permit DOT SP-13556 relating to the transport of
regulated medical waste into the HMR.
    Specifically, PHMSA is proposing to add the phrase ``sharps
containers containing sharps'' to Sec.  173.134(c)(2) to permit certain
materials to be transported on a vehicle used exclusively to transport
RMW. PHMSA is also proposing to include certain operational controls
for shipments of sharps containers that are detailed in special permit
DOT SP-13556.
Section 173.150
    Section 173.150 provides exceptions from the HMR for certain Class
3 flammable liquid material. Specifically, Sec.  173.150(d) provides
exceptions for alcoholic beverages for all modes of transport. An
alcoholic beverage (as defined in 27 CFR Sec. Sec.  4.10 and 5.11) that
meets one of three conditions specified in Sec.  173.150(d) is not
subject to the requirements of the HMR for a Class 3 flammable liquid
material.
    Currently, the ICAO Technical Instructions (TI) provide exceptions
for alcoholic beverages transported via aircraft in Chapter 3; 3.1.1,
Table 3-2, special provision A9 and Chapter 8; 8.1.2 paragraph (l).
Specifically, Chapter 3; 3.1.1 states that alcoholic beverages
containing not more than 70 percent alcohol by volume, when packaged in
receptacles of 5 liters or less are not subject to the ICAO TI when
carried by cargo aircraft. In addition, as specified in Chapter 8;
1.1.2 paragraph (l) of the ICAO TI, alcohol beverages with less than 24
percent alcohol by volume or alcohol beverages in retail packaging and
alcoholic beverages containing more than 24 percent but not more than
70 percent alcohol by volume in receptacles not exceeding 5 liters are
permitted to be carried by passengers or crew in carry-on or checked
luggage and are not otherwise subject to the ICAO TI.
    Generally, the HMR is harmonized with the ICAO TI with regard to
the exceptions provided for alcoholic beverages shipped by passenger
carrying and cargo aircraft. However, for cargo aircraft, the HMR does
not align with the ICAO TI. For example, as specified in Sec.
173.150(d), the HMR excepts alcoholic beverages in an inner packaging
of 5 L (1.3 gallons) or less from regulation regardless of the alcohol
percent on cargo aircraft. In contrast, the ICAO TI limits this
exception to alcoholic beverages not exceeding 70 percent alcohol by
volume. This lack of harmonization can lead to frustration of shipments
of these types of materials in international air transport.
    Therefore, in this NPRM, we propose to revise the exceptions in
Sec.  173.150(d) to harmonize the alcoholic beverages exception via
aircraft with the requirements in the ICAO TI and to restructure the
exceptions in Sec.  173.150(d) to provide clarity on the requirements
for the transport of alcoholic beverages by each mode of transport
including passenger carrying and cargo aircraft. Specifically, PHMSA
proposes to revise Sec.  173.150(d) by separating the requirements for
alcoholic beverages into two subparagraphs: one paragraph pertaining to
the transport of alcoholic beverages via motor vehicle, rail, and
vessel; and one paragraph pertaining to the transport of alcoholic
beverages via air transport. We believe that separating the
requirements for alcoholic beverages by mode promotes clarity and
allows for the current requirements to remain in effect for motor
vehicle, rail and vessel transport while fully harmonizing the air
requirements in the HMR with the ICAO TI.
    PHMSA proposes to harmonize with the ICAO technical instructions by
stipulating that for transport via cargo aircraft, in addition to the
current 5 liter limitation in the HMR, the alcohol beverage must not
exceed 70 percent alcohol by volume. In addition, we propose to move
the requirements for the transport of alcoholic beverages by passenger
carrying aircraft by passengers and crew into a standalone sub-
subparagraph to improve clarity.
    A cost may be incurred by the alcoholic beverage industry for
certain high alcohol content (70 percent and up) beverages shipped by
cargo aircraft which are currently excepted from the requirements of
the HMR. However, PHMSA anticipates this cost to the alcoholic beverage
industry will be minimized by three factors. First, due to the non-
perishable nature of alcoholic beverages, the vast majority of
alcoholic beverages are transported by ground transport or, if required
to be exported, by vessel transport. Second, the majority of alcohols
and distilled spirits manufactured and transported have a percentage of
alcoholic content of, at, or below 40 percent (80 proof). Thus the
proposed change would affect only a small segment of high alcohol
content liquors. Lastly, in the rare instances these beverages are
shipped by air, many air carriers already require compliance with ICAO
TI, thus the impact of this harmonization should be minimal. The
derived benefit from this revision would be realized from increased
harmonization with the ICAO TI and greater hazard communication and
packaging standards on high content alcoholic beverages which pose a
risk in transport. A summary of the proposed revisions to the
requirements for alcoholic beverages can be seen in the table below.

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

Section 173.159a
    Section 173.159 specifies requirements for the transportation of
wet batteries, including non-spillable batteries. Further exceptions
for non-spillable batteries are specified in Sec.  173.159a. If certain
transport conditions specified in Sec. Sec.  173.159 and 173.159a are
met, such as specific packaging and securement requirements, non-
spillable batteries are excepted from the HMR.
    In a final rule published on January 14, 2009, under Docket Nos.
PHMSA-2007-0065 (HM-224D) and PHMSA-2008-0005 (HM-215J) [74 FR 2200],
entitled ``Hazardous Materials: Revision to Requirements for the
Transportation of Batteries and Battery-Powered Devices; and
Harmonization With the United Nations Recommendations, International
Maritime Dangerous Goods Code, and International Civil Aviation
Organization's Technical Instructions,'' PHMSA amended Sec.  173.159(f)
to describe the conditions under which a battery is considered ``non-
spillable,'' and relocated the exceptions pertaining to non-spillable
batteries from Sec. Sec.  173.159(d) and 173.159(f), to a new Sec.
173.159a.
    However, when these exceptions were relocated, PHMSA inadvertently
required that excepted non-spillable batteries must be securely
packaged in strong outer packagings. This modification, in essence,
prohibited excepted batteries from being palletized or placed on a
skid. Therefore, in this NPRM, PHMSA is proposing to revise Sec.
173.159a(c)(1) to except from the packaging requirements of Sec.
173.159, non-spillable batteries that are secured to skids or pallets
and capable of withstanding the shocks normally incident to
transportation, provided the batteries meet the requirements of Sec.
173.159(a) and are loaded or braced so as to prevent damage and short
circuits in transit. Further, any other material loaded in the same
vehicle must be blocked, braced, or otherwise secured to prevent
contact with or damage to the batteries.

Part 177

Section 177.834
    Section 177.834 provides the general requirements for the loading
and unloading of vehicles intended to transport hazardous materials via
ground transportation. Paragraph (j) of this section requires CTMVs to
be transported with all valves and other closures in liquid discharge
systems to be closed and free of leaks unless transported in accordance
with the requirements for empty packages specified in Sec.
173.29(b)(2).
    The provision specified in Sec.  177.834(j) was added on May 30,
1996, in a final rule published under Docket Number HM-222B [61 FR
27166] to consolidate the closure requirements for cargo tanks
transporting Class 3 (flammable liquid) materials, Class 8 (corrosive)
materials, and Division 6.1 (poisonous) materials. This rule
inadvertently overlooked the impact the closure requirement would have
on MC 338 cargo tanks that transport cryogenic liquids. These tanks
have external self-closing valves that are normally transported in an
open position and are designed to close with a tremendous amount of
force to ensure proper closure. Subsequently, these valves require a
large amount of force and effort to open. As a result, the potential
for physical injury to employee personnel is increased and the ability
of the valve system to operate is potentially compromised as a result
of repeated cycling (opening, closing, and testing).
    Therefore, in this NPRM, we propose to revise Sec.  177.834(j) to
permit external emergency self-closing valves on MC 338 cargo tanks
containing residues of cryogenic liquids to remain either open or
closed during transit.

Part 178

Section 178.2
    Section 178.2 specifies the responsibilities of the manufacturer or
other person certifying compliance with the specification packaging
requirements of Part 178. As part of these requirements, the
manufacturer or other person certifying compliance with the
requirements of Part 178 must provide both notification to each person
to whom a packaging is transferred of all requirements in Part 178 not
met at the time of transfer, and closure requirements for the
packaging. These closure requirements include information specifying
the type(s) and dimensions of the closures, including gaskets and any
other components needed to ensure that the packaging is capable of
successfully passing the applicable performance tests. This information
must include any procedures to be followed, including closure
instructions for inner packagings and receptacles, to effectively
assemble and close the packaging for the purpose of preventing leakage
in transportation. Closure instructions must provide for a consistent
and repeatable means of closure that is sufficient to ensure the
packaging is closed in the same manner as it was tested.
    A package, as defined in Sec.  171.8, ``means a packaging plus its
contents.'' Ensuring that a package is closed in a manner which
precludes the release of a hazardous material is essential to safe
transportation, regardless of whether the package is completely filled
or contains only residue. In accordance with Sec.  173.29, an empty
packaging containing only the residue of a hazardous material must be
offered for transportation and transported in the same manner as when
it previously contained a greater quantity of that hazardous material.
This includes properly closing the packaging for transportation and
providing closure notification requirements to each person whom a
packaging is transferred in accordance with Sec.  178.2(c).
    In April 2006, PHMSA received a request (Reference No.: 06-0123)
seeking clarification of the closure notification requirements
specified in Sec.  178.2(c) for packages containing residues. In
response, we indicated that packages containing residues must meet the
notification requirements of Sec.  178.2(c) and that we would clarify
this issue in a future rulemaking.
    In this rulemaking, PHMSA is addressing this issue by proposing to
revise Sec.  178.2(c) to clarify that the notification requirements
apply to packagings containing a residue of a hazardous materials
unless these packagings of hazardous materials meet the exceptions
provided in Sec.  173.29(b). This clarification will ensure packages
containing residues are properly closed and increase compliance with
the intent of this regulation. This increased compliance should also
result in fewer packages being improperly closed, and thereby reduce
the potential for leaks in transportation.
    Certain CTMVs require as part of their specification both a CTMV
manufacturer's data report and a certificate stating that the completed
cargo tank motor vehicle conforms in all respects to the appropriate
specification and the American Society of Mechanical Engineers (ASME)
Code. Section 178.2(c) currently excepts CTMVs which require a
manufacturer's data report and certificate from the notification
requirements. Specifically, Sec.  178.2(c) states that CTMV's in
compliance with Sec. Sec.  178.337-18 and 178.345-10 are excepted from
the notification requirements specified in Sec.  178.2(c). The current
reference to Sec.  178.345-10 in paragraph Sec.  178.2 (c) refers to
pressure relief, not the CTMV manufacturer's data report and
certificates for DOT 406, 407 and 412 (CTMVs), and is in error. The
correct citation should read Sec.  178.345-15, which refers to the
manufacturer's data report and certification of DOT 406, 407 and 412
CTMVs. In addition, it was brought to PHMSA's attention that a
reference to a MC 338 cargo tank manufacturer's data report certificate
in Sec.  178.338-19 is missing in Sec.  178.2(c).
    We agree and believe that a reference to a MC 338 cargo tank
manufacturer's data report certificate would be appropriate in Sec.
178.2(c). Therefore, in this rulemaking, we propose to correct these
errors and omissions by replacing the reference to Sec.  178.345-10
with Sec.  178.345-15 and adding a reference to Sec.  178.338-19.
Appendix E to Part 178
    Appendix E to Part 178 describes the Flame Penetration Resistance
Test referenced throughout the HMR with regard to the outer packaging
for chemical oxygen generators and cylinders containing compressed
oxygen. This appendix specifies requirements for the Flame Penetration
Resistance Test and includes criteria for acceptance of a passing test
result, a summary of the test method and procedure, details on the
preparation of test specimens, and construction and calibration
specifications for the test equipment.
    On January 31, 2007, PHMSA published a final rule under docket
number RSPA-04-17664 (HM-224B) [72 FR 4442] entitled ``Transportation
of Compressed Oxygen, Other Oxidizing Gases and Chemical Oxygen
Generators on Aircraft,'' which included amendments that changed
packaging and marking requirements for air shipments of compressed
oxygen cylinders and chemical oxygen generators. As of October 1, 2009,
certain compressed gases shipped by air, and chemical oxygen generators
must be placed in a rigid outer packaging demonstrated to withstand
both flame penetration and thermal resistance testing requirements.
    Appendix E specifies the procedures to follow to conduct the Flame
Penetration Resistance Test. The test procedure is described in
sections (g)(2) of this Appendix and references a ``Figure 1,'' but
HMR, Figure 1 is omitted. In sections (d)(3) and (f)(2) of this
Appendix, the design and calibration of the calorimeter is described
and refers to a ``Figure 2,'' but Figure 2 is also omitted. Therefore,
in this NPRM, PHMSA is proposing to add Figures 1 and 2 that were
referenced but inadvertently omitted from Appendix E.

Part 180

Section 180.416
    Section 180.416 details the requirements for a discharge system
inspection and maintenance program for cargo tanks transporting
liquefied compressed gases. Specifically, Sec.  180.416 applies to
operators using specification MC 330, MC 331, and non-specification
cargo tanks authorized under Sec.  173.315(k) for transportation of
liquefied compressed gases other than carbon dioxide. As part of the
discharge system inspection specified in this section, the operator
must visually inspect each delivery hose assembly at least once each
calendar month in which the delivery hose assembly is in service and
keep a record of each inspection. In accordance with Sec.  180.416(d),
that record must include the inspection date, the name of the person
performing the inspection, the hose assembly identification number, the
company name, the date the hose was assembled and tested, and an
indication that the delivery hose assembly and piping system passed or
failed the tests and inspections.
    There has been some confusion among the regulated community
pertaining to the requirement to include ``the company name'' in the
record as specified in Sec.  180.416(d). Specifically, there was
concern over whether ``the

company name'' refers to the name of the operator or the name of the
manufacturer of the hose.
    In this NPRM, PHMSA proposes to revise Sec.  180.416(d) to clarify
that the reference to the ``company name'' on the inspection record is
the name of the hose manufacturer. We believe this proposed revision
will clarify the requirement for discharge system inspection records,
resulting in more accurate records for specification MC 330, MC 331,
and non-specification cargo tanks authorized under Sec.  173.315(k)
transporting of liquefied compressed gases other than carbon dioxide.

III. Regulatory Analyses and Notices

A. Statutory/Legal Authority for This Rulemaking

    This NPRM is published under authority of Federal hazardous
materials transportation law (Federal hazmat law; 49 U.S.C. 5101 et
seq.). Section 5103(b) of Federal hazmat law authorizes the Secretary
of Transportation to prescribe regulations for the safe transportation,
including security, of hazardous materials in intrastate, interstate,
and foreign commerce. If adopted as proposed, this NPRM would make
miscellaneous amendments to the HMR. In addition, if adopted as
proposed, this NPRM would correct errors in the hazardous materials
table and corresponding special provisions, clarify the requirements
for lab packing temperature controlled materials and clarify various
cargo tank provisions and revise the training requirements to require
that a hazmat employer must make hazmat employee training records
available upon request to an authorized officials. These amendments
clarify regulatory requirements and, where appropriate, decrease the
regulatory burden without compromising the safe transportation of
hazardous materials in commerce.

B. Executive Order 12866, Executive Order 13563 and DOT Regulatory
Policies and Procedures

    This proposed rule is not considered a significant regulatory
action under section 3(f) and was not reviewed by the Office of
Management and Budget (OMB). The proposed rule is not considered a
significant rule under the Regulatory Policies and Procedures order
issued by the Department of Transportation [44 FR 11034].
    In this notice of proposed rulemaking, we propose to amend
miscellaneous provisions in the HMR to clarify the provisions and to
relax overly burdensome requirements. PHMSA anticipates the proposals
contained in this rule will have economic benefits to the regulated
community. This NPRM is designed to increase the clarity of the HMR,
thereby increasing voluntary compliance while reducing compliance
costs.
    Executive Order 13563 is supplemental to and reaffirms the
principles, structures, and definitions governing regulatory review
that were established in Executive Order 12866 Regulatory Planning and
Review of September 30, 1993. In addition, Executive Order 13563
specifically requires agencies to: (1) Involve the public in the
regulatory process; (2) promote simplification and harmonization
through interagency coordination; (3) identify and consider regulatory
approaches that reduce burden and maintain flexibility; (4) ensure the
objectivity of any scientific or technological information used to
support regulatory action; and (5) consider how to best promote
retrospective analysis to modify, streamline, expand, or repeal
existing rules that are outmoded, ineffective, insufficient, or
excessively burdensome.
    In this NPRM, PHMSA has involved the public in the regulatory
process in a variety of ways. Specifically, in this rulemaking PHMSA is
addressing issues and errors that were identified and tagged for future
rulemaking consideration in letters of interpretation issued to the
regulated community and through other correspondence with PHMSA
stakeholders. In addition, PHMSA has responded to the TSI's request to
incorporate a guidance document designed to assist the sulphur industry
in ensuring the safe transport of molten sulphur (P-1581). PHMSA is
asking for public comments based on the proposals in this NPRM. Upon
receipt of public comment, PHMSA will address all substantive comments
in the next rulemaking action under this docket number.
    The amendments in the NPRM promote simplification and harmonization
through interagency coordination. Specifically, in this NPRM, PHMSA is
simplifying the lab packing requirements, the hazardous materials table
and special provisions and the requirements for cargo tank
transportation. These revisions are expected to produce a safety
benefit derived from the increased clarity and reduced ambiguity in the
special provisions to the Sec.  172.101 HMT, and the lab packaging and
cargo tank requirements of the HMR. There are minimal additional costs.
The clarity will result in net benefits.
    This NPRM also promotes harmonization with international standards,
such as the IMDG Code, Canada's TDG requirements and the ICAO TI with
regard to the handling of ``Lead compounds, soluble n.o.s.'' via
vessel, rail shipments of residue between the United States and Canada
and alcoholic beverages via aircraft.
    These revisions to the Sec.  172.101 HMT will eliminate errors in
the Sec.  172.101 HMT, reduce ambiguity, harmonize the HMR with
international regulations, and improve clarity. Many of these revisions
were brought to PHMSA's attention through letters of interpretation
requested from the regulated community. Although these revisions are
minor, they are expected to produce a safety benefit derived from the
increased clarity and accuracy of the text in the Sec.  172.101 HMT.
    This NPRM proposes approaches that reduce the regulatory burden on
the regulated community, allows for flexibility in achieving compliance
and maintains an appropriate level of safety. This NPRM permits
flexibility in achieving compliance when transporting cargo tanks while
maintaining an appropriate level of safety. This NPRM also incorporates
a special permit DOT SP-13556 that has a strong record of safety.
Incorporating this permit into the HMR will provide wider access to the
benefits of the provisions granted in this special permit, therefore,
fostering greater regulatory flexibility without compromising
transportation safety.
    A majority of the amendments in this rulemaking are simple
clarifications and do not require significant scientific or
technological information. However, when necessary in this NPRM, PHMSA
used scientific or technological information to support its regulatory
action. Specifically, such data was considered when structuring
alternatives on how to best deal with issues regarding the safe
transport of cargo tanks and the transport of alcoholic beverages with
greater than 70 percent alcohol by volume via cargo aircraft. This
information was used in the evaluation of alternative proposals and
ultimately this information determined how best to promote
retrospective analysis to modify and streamline existing requirements
that are outmoded, ineffective, insufficient, or excessively
burdensome.

C. Executive Order 13132

    This proposed rule was analyzed in accordance with the principles
and criteria contained in Executive Order 13132 (``Federalism''). This
proposed rule would preempt state, local and

Indian tribe requirements but does not propose 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.
5125(b)(1), contains an express preemption provision (49 U.S.C.
5125(b)) preempting 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
related to hazardous materials and requirements related to the number,
content, and placement of those documents;
    (iv) The written notification, recording, and reporting of the
unintentional release in transportation of hazardous materials; or
    (v) The design, manufacture, fabrication, marking, maintenance,
reconditioning, repair, or testing of a packaging or container which is
represented, marked, certified, or sold as qualified for use in the
transport of hazardous materials.
    This proposed rule concerns the classification, packaging, and
handling of hazardous materials, among other covered subjects. If
adopted, this rule would preempt any state, local, or Indian tribe
requirements concerning these subjects unless the non-Federal
requirements are ``substantively the same''(see 49 CFR 107.202(d) as
the Federal requirements.)
    Federal hazardous materials transportation law provides at 49
U.S.C. 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. 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.
PHMSA proposes the effective date of federal preemption be 90 days from
publication of a final rule in this matter in the Federal Register.

D. Executive Order 13175

    This proposed 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 proposed rule does not have tribal implications and does
not impose substantial direct compliance costs on Indian tribal
governments, the funding and consultation requirements of Executive
Order 13175 do not apply, and a tribal summary impact statement is not
required.

E. Regulatory Flexibility Act, Executive Order 13272, and DOT
Procedures and Policies

    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 the rule is not expected to have a
significant impact on a substantial number of small entities. This
proposed rule would amend miscellaneous provisions in the HMR to
clarify provisions based on our PHMSA's initiatives and correspondence
with the regulated community. While maintaining safety, it would relax
certain requirements that are overly burdensome. The proposed changes
are generally intended to provide relief to shippers, carriers, and
packaging manufacturers, including small entities.
    Consideration of alternative proposals for small businesses. The
Regulatory Flexibility Act directs agencies to establish exceptions and
differing compliance standards for small businesses, where it is
possible to do so and still meet the objectives of applicable
regulatory statutes. In the case of hazardous materials transportation,
it is not possible to establish exceptions or differing standards and
still accomplish our safety objectives.
    The impact of this proposed rule is not expected to be significant.
The proposed changes are generally intended to provide relief to
shippers, carriers, and packaging manufactures and testers, including
small entities. This relief will provide marginal positive economic
benefits to shippers, carriers, and packaging manufactures and testers,
including small entities however; these benefits are not at a level
that can be considered economically significant. Therefore, this
proposed rule will not have a significant economic impact on a
substantial number of small entities.
    This proposed rule has been developed in accordance with Executive
Order 13272 (``Proper Consideration of Small Entities in Agency
Rulemaking'') and DOT's procedures and policies to promote compliance
with the Regulatory Flexibility Act to ensure that potential impacts of
draft rules on small entities are properly considered.

F. Paperwork Reduction Act

    This proposed rule does not impose any new information collection
requirements and in three instances marginally decreases the
information collection burden on the reregulated community.
Specifically the following information collections affected by this
rulemaking are:
     Office of Management and Budget (OMB) Control Number 2137-
0051; Rulemaking and Special Permit Petitions: A slight reduction in
information collection burden is anticipated due to the incorporation
of a DOT SP-13556 into Sec.  173.134. This permit will allow
individuals more flexibility when transporting sharps and decrease the
need for special permits applications when transporting sharps as
regulated medical wastes.
     OMB Control Number 2137-0034; Hazardous Materials Shipping
Papers and Emergency Response Information: A negligible reduction in
information collection burden due to relaxation of the shipping paper
description requirements for residues specified in Sec.  172.203.
Specifically, this will allow individuals more flexibility on the
shipping paper descriptions when shipping waste internationally, and
will correct a regulatory inconsistency between the HMR and Canadian
Hazardous materials regulations, fostering international transport of
residues.
     OMB Control Number 2137-0557; Approvals for Hazardous
Materials: A slight reduction in information collection burden is
anticipated due to relaxation of approval submittal requirements
specified in Sec.  105.40. Specifically, this relaxation will permit
individuals wishing to apply with PHMSA to be an approved designated
agent to submit their applications either by standard mail or
electronic mail. Currently, the HMR only permits submission through
standard mail. This change will result in a decrease in duplicate hard
copies submitted to PHMSA as well as a decrease in the processing time
for such applications.

G. 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.

H. Unfunded Mandates Reform Act

    This proposed rule does not impose unfunded mandates under the
Unfunded Mandates Reform Act of 1995. It does not result in costs of
$141,300,000 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.

I. Environmental Assessment

    The National Environmental Policy Act, 42 U.S.C. 4321-4375,
requires federal agencies to analyze proposed actions to determine
whether the action will have a significant impact on the human
environment. The Council on Environmental Quality (CEQ) regulations
require federal agencies to conduct an environmental review
considering: (1) The need for the proposed action; (2) alternatives to
the proposed action; (3) probable environmental impacts of the proposed
action and alternatives; and (4) the agencies and persons consulted
during the consideration process. PHMSA proposes to make miscellaneous
amendments to the HMR based on PHMSA's own initiatives including a
review of the HMR, previous letters of interpretation and special
permits we issued. The proposed amendments are intended to update,
clarify, or provide relief from certain existing regulatory
requirements to promote safer transportation practices; eliminate
unnecessary regulatory requirements; facilitate international commerce;
and make these requirements easier to understand.

    Description of Action:
Docket No. PHMSA-2011-0138 (HM-218G), NPRM
    Transportation of hazardous materials in commerce is subject to
requirements in the HMR, issued under authority of Federal hazardous
materials transportation law, codified at 49 U.S.C. 5001 et seq. To
facilitate the safe and efficient transportation of hazardous materials
in international commerce, the HMR provide that both domestic and
international shipments of hazardous materials may be offered for
transportation and transported under provisions of the international
regulations.

    Proposed Amendments to the HMR:

    In this NPRM, PHMSA is proposing to:
     Permit designated agents for non-residents to submit
designation requests by electronic mail in addition to traditional
mail.
     Add the TSI ``Molten Sulphur Rail Tank Car Guidance''
document to the list of informational materials not requiring
incorporation by reference in Sec.  171.7.
     Revise the Sec.  172.101 HMT to correct an error in the
transportation requirements for entries listed under the proper
shipping name, ``Hydrazine Dicarbonic Acid Diazide.''
     Revise the Sec.  172.101 HMT to remove the entry for
``Zinc ethyl, see Diethylzinc'' which was superseded by proper shipping
names adopted in a previous rulemaking.
     Revise special provision 138 in Sec.  172.102 to clarify
the lead solubility calculation utilized for classification of material
as a Marine Pollutant.
     Remove references to special provisions B72 and B74 in
Sec.  172.102. These special provisions were removed in a previous
rulemaking, however, twelve entries in the Sec.  172.101 HMT still
contain references to these special provisions.
     Revise the shipping paper requirements in Sec.  172.203(e)
to permit the phrase ``Residue last contained'' to be placed before or
after the basic shipping description sequence, or for rail shipment,
directly preceding the proper shipping name in the basic shipping
description sequence.
     Update the training recordkeeping requirements in Sec.
172.704 to specify that a hazardous materials (hazmat) employer must
make hazmat employee training records available upon request, at a
reasonable time and location, to an authorized official of the
Department of Transportation or the Department of Homeland Security.
     Clarify that the material of trade exception in Sec.
173.6 may be used when transporting Division 2.1 and 2.2 gases in Dewar

    Alternatives Considered:

    Alternative (1): Do nothing.
    Our goal is to update, clarify and provide relief from certain
existing regulatory requirements to promote safer transportation
practices, eliminate unnecessary regulatory requirements, and
facilitate international commerce. We rejected the do-nothing
alternative.
    Alternative (2): Go forward with the proposed amendments to the HMR
in this NPRM.
    This is the selected alternative.
Environmental Consequences
    Hazardous materials are substances that may pose a threat to public
safety or the environment during transportation because of their
physical, chemical, or nuclear properties. The hazardous materials
regulatory system is a risk management system that is prevention
oriented and focused on identifying a safety hazard and reducing the
probability and quantity of a hazardous material release. Hazardous
materials are categorized by hazard analysis and experience into hazard
classes and packing groups. The regulations require each shipper to
classify a material in accordance with these hazard classes and packing
groups. The process of classifying a hazardous material is itself a
form of hazard analysis. Further, the regulations require the shipper
to communicate a material's hazards through use of the hazard class,
packing group, and proper shipping name on the shipping paper and the
use of labels on packages and placards on transport vehicles. Thus, the
shipping paper, labels, and placards communicate the most significant
findings of the shipper's hazard analysis. A hazardous material is
assigned to one of three packing groups based upon its degree of
hazard, from a high hazard, Packing Group I to a low

hazard, Packing Group III material. The quality, damage resistance, and
performance standards of the packaging in each packing group are
appropriate for the hazards of the material transported.
    Under the HMR, hazardous materials are transported by aircraft,
vessel, rail, and highway. The potential for environmental damage or
contamination exists when packages of hazardous materials are involved
in accidents or en route incidents resulting from cargo shifts, valve
failures, package failures, loading, unloading, collisions, handling
problems, or deliberate sabotage. The release of hazardous materials
can cause the loss of ecological resources (e.g. wildlife habitats) and
the contamination of air, aquatic environments, and soil. Contamination
of soil can lead to the contamination of ground water. Compliance with
the HMR substantially reduces the possibility of accidental release of
hazardous materials.
Conclusion
    PHMSA proposes to make miscellaneous amendments to the HMR based on
comments from the regulated community and PHMSA's own rulemaking
initiatives. The proposed amendments are intended to update, clarify,
or provide relief from certain existing regulatory requirements to
promote safer transportation practices; eliminate unnecessary
regulatory requirements; facilitate international commerce; and make
these requirements easier to understand. These proposed clarifications
of regulatory requirements, if adopted, will foster a greater level of
compliance with the HMR and thus, diminished levels of hazardous
materials transportation incidents affecting the health and safety of
the environment. Therefore, the net environmental impact of this
proposal will be positive.

K. International Trade Analysis

    The Trade Agreements Act of 1979 (Pub. L. 96-39), as amended by the
Uruguay Round Agreements Act (Pub. L. 103-465), prohibits Federal
agencies from establishing any standards or engaging in related
activities that create unnecessary obstacles to the foreign commerce of
the United States. Pursuant to these Acts, the establishment of
standards are not considered unnecessary obstacles to the foreign
commerce of the United States, so long as the standards have a
legitimate domestic objective, such as the protection of safety, and do
not operate in a manner that excludes imports that meet this objective.
The statute also requires consideration of international standards and,
where appropriate, that they be the basis for U.S. standards. PHMSA
notes the purpose is to ensure the safety of the American public, and
has assessed the effects of this rule to ensure that it does not
exclude imports that meet this objective. As a result, this proposed
rule is not considered as creating an unnecessary obstacle to foreign
commerce.
