I. Background

A. Notice of Proposed Rulemaking (NPRM)

    On April 26, 2012, PHMSA published a NPRM under Docket PHMSA 2011-
0138 [77 FR 24885] (HM-218G) that proposed amendments to update and
clarify existing requirements of the HMR. The NPRM and this Final Rule
are part of the Department of Transportation's Retrospective Regulatory
Review (RRR) designed to identify ways to improve the Hazardous
Materials Regulations (HMR; 49 CFR parts 171-180). The NPRM proposed
amendments to update and clarify existing requirements by incorporating
changes into the HMR 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, the NPRM proposed to
incorporate a special permit with a longstanding history of safety into
the HMR and respond to a petition for rulemaking. The changes proposed
in the April 26, 2012 NPRM are summarized below:
     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``Zinc ethyl, see Diethylzinc'' that was superseded by proper shipping
names adopted in a previous rulemaking.
     Add the inadvertently omitted entries for ``Paint related
material, flammable, corrosive (including paint thinning or reducing
compound)'' UN3469, PG II, and PG III to the Sec.  172.101 HMT.
     Remove references to special provisions B72 and B74 in
Sec.  172.102.
     Revise special provision 138 in Sec.  172.102 to clarify
the lead solubility calculation used to classify a material as a Marine
Pollutant.
     Revise the shipping paper requirements in Sec.  172.203(e)
to permit the placement of phrase ``Residue last contained'' 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 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 (DHS).
     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 in 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
closure notification requirements for packages containing residues.
     Correct regulatory citations in Sec.  178.2(c).
     Clarify the requirements for the Flame Penetration
Resistance test specified for chemical oxygen generators and certain
compressed gases in Appendix E to Part 178.
     Clarify the inspection record requirements in Sec.
180.416 for discharge systems of cargo tanks transporting liquefied
compressed gases.

B. Commenters

    The comment period for the April 26, 2012 NPRM closed on June 25,
2012. PHMSA received 22 public comments in response to the NPRM's
proposed amendments, from trade associations representing various
industries, individual businesses, and concerned citizens who make up
the regulated community. While the majority of the commenters supported
the proposals in the NPRM, some commenters expressed adverse opinions
with specific proposals. In response to the feedback provided by these
commenters, PHMSA will address and discuss both the proposals adopted
and not adopted into the HMR by this rulemaking under the heading,
``Discussion of Amendments and Applicable Comments.'' In addition, some
commenters provided suggestions for revisions that were not
specifically addressed in the NPRM, and therefore, are considered
beyond the scope of this rulemaking. The comments, as submitted to this
docket, may be accessed via http://www.regulations.gov and were
submitted by the following individuals, companies, and associations
(abbreviations used throughout the document and Docket Reference

II. Discussion of Amendments and Applicable Comments

A. General Comments

    On September 30, 1993, President Bill Clinton issued Executive
Order 12866 which asked Federal agencies ``to enhance planning and
coordination with respect to both new and existing regulations; to
reaffirm the primacy of Federal agencies in the regulatory decision-
making process; to restore the integrity and legitimacy of regulatory
review and oversight; and to make the process more accessible and open
to the public.''
    On October 21, 2011, President Barack Obama issued Executive Order
13563 which is supplemental to and reaffirms the principles,
structures, and definitions governing contemporary regulatory review
that were established in Executive Order 12866. This executive order
urged government agencies to consider regulatory approaches that reduce
burdens and maintain flexibility and freedom of choice for the public.
Finally, federal agencies were directed to periodically review existing
significant regulations; retrospectively analyze rules that may be
outmoded, ineffective, insufficient, or excessively burdensome; and
modify, streamline, expand, or repeal regulatory requirements in
accordance with what has been learned.
    On May 10, 2012, President Barack Obama issued Executive Order
13610 (Identifying and Reducing Regulatory Burdens) reaffirming the
goals of Executive Order 13563 (Improving Regulation and Regulatory
Review) issued January 18, 2011, and Executive Order 12866 (Regulatory
Planning and Review) issued September 30, 1993. Executive Order 13610
directs agencies to prioritize ``those initiatives that will produce
significant quantifiable monetary savings or significant quantifiable
reductions in paperwork burdens while protecting public health,
welfare, safety, and our environment.'' Executive Order 13610 further
instructs agencies to give consideration to the cumulative effects of
their regulations, including cumulative burdens, and prioritize reforms
that will significantly reduce burdens.
    In accordance with Executive Orders 13610 and 13563, PHMSA has
undertaken a retrospective review of the HMR. This final rule and the
NPRM that preceded it are part of that initiative, and were based on an
internal review of the HMR, special permits, petitions, and letters of
interpretation. The April 26, 2012 NPRM specifically addressed a
petition, a special permit, and various clarifications identified in
letters of interpretation and through PHMSA internal review of the HMR.
The publication of the NPRM provided an opportunity for further public
participation in the development of the regulatory amendments, and
promoted an exchange of information and perspectives among the various
stakeholders.
    PHMSA received 22 comments in response to the April 26, 2012 NPRM
which were predominately positive. Some commenters agreed in principle
with the proposed amendments and offered revisions to improve the
clarity of the regulatory text. In some cases, no comments to proposed
amendments were received. In these circumstances, PHMSA attributed the
lack of comment to either the nature of the amendment being editorial,
or a general acknowledgement from the regulated community that no
opposition to the change was warranted. Finally, negative comments were
also received on some specific issues. A detailed description of the
original proposals in the April 26, 2012 NPRM, a summary of the
comments received, responses to those comments, and PHMSA's decision on
future actions are detailed below.

B. Provisions Adopted in This Final Rule and Discussion of Comments

    In this section, PHMSA discusses the changes proposed in the NPRM
and the comments received in response to the NPRM. To clearly identify
the issues addressed in this final rule, PHMSA provides the following
list of adopted amendments discussed in this section:
     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 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'' that was superseded by proper shipping
names adopted in a previous rulemaking.
     Add the entries for ``Paint related material, flammable,
corrosive (including paint thinning or reducing compound)'' UN3469, PG
II, and PG III to the Sec.  172.101 HMT that were inadvertently
omitted.
     Remove references to special provisions B72 and B74 in
Sec.  172.102.
     Revise special provision 138 in Sec.  172.102 to clarify
the lead solubility calculation used to classify a material as a Marine
Pollutant.
     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 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 of an entity explicitly granted authority to enforce the HMR.
     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 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 ICAO TI.
     Clarify the exceptions in Sec.  173.159a for non-spillable
batteries secured to skids or pallets.
     Correct regulatory citations in Sec.  178.2(c).
     Clarify the requirements for the Flame Penetration
Resistance test specified for chemical oxygen generators and certain
compressed gases in Appendix E to Part 178.
     Clarify the inspection record requirements in Sec.
180.416 for discharge systems of cargo tanks transporting liquefied
compressed gases.

Designated Agents for Non-Residents
    Currently, Sec.  105.40 prescribes 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.
    The HMR only permit designated agent notification documents to be
mailed to the Approvals and Permits Division, PHMSA, 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 the April 26, 2012 NPRM, PHMSA proposed 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.
    PHMSA received no comments on the proposed change to the
requirements for designated agents for non-residents. Therefore, we are
adopting these amendments to Sec.  105.40(d), as proposed in the NPRM.
Molten Sulphur Tank Rail Car Guidance Document
    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 are not mandatory but, may enhance
safety and compliance.
    The Sulphur Institute (TSI) represents the sulfur industry in the
United States on a variety of issues including the safe transportation
of sulfur in commerce. TSI submitted petition P-1581 (Docket Number
PHMSA-2007-28054) requesting that PHMSA incorporate by reference TSI's
``Molten Sulphur Tank Rail Car Guidance Document.'' This document
provides best practices for the safe transport of molten sulfur in rail
tank cars. 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.''
    In the NPRM published on April 26, 2012, PHMSA proposed to adopt
``Molten Sulphur Rail Tank Car Guidance'' in the list of informational
materials not requiring incorporation by reference in Sec.  171.7(b).
In addition, PHMSA proposed 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. PHMSA did not propose adding TSI's
suggested language ``Dried residue of molten sulfur on tank cars shall
meet the `Molten Sulphur Rail Car Guidance Document' incorporated by
reference in Sec.  171.7'' to Sec.  173.24(b)(4).
    PHMSA received eight comments on the proposed addition of the
``Molten Sulphur Rail Tank Car Guidance'' to the list of informational
materials not requiring incorporation by reference and subsequent
addition of special provision ``R1.'' Seven of these comments expressed
support: KOCH, Oxbow, PCS, TFI, Transammonia, TSI, and UTCC. KOCH, who
ships more than 500,000 tons of sulfur annually; Oxbow, who ships over
13,000 railcars of molten sulfur annually; PCS who receives 1.6 million
tons of sulfur annually; Transammonia, who ships over 2,500 railcars of
molten sulfur annually; and UTCC, who provides the means of
transporting sulfur in approximately 1,100 tank cars, note that they
all assisted in developing this document and believe it will benefit
carriers, government inspectors, and shippers by promoting safer
handling practices. TFI, a national trade association representing
fertilizer importers, producers, retailers and wholesalers, reiterates
the comments of these companies. In addition to expressing support for
the adoption of this document, one commenter, TSI, offers two minor
editorial changes to the proposed regulatory text. Specifically, TSI
requests PHMSA update the mailing address listed for TSI and that PHMSA
revise the edition listed for the document.
    In contrast, the AAR, on behalf of itself and its member railroads,
provided comments that strongly oppose the proposed amendment. AAR
states its belief that the TSI guidance contradicts certain
requirements specified in the HMR. Specifically, AAR notes that Sec.
173.24(b)(4) specifies ``there will be no hazardous materials residue
adhering to the outside of a package during transport.'' Furthermore,
Sec.  174.57 specifies ``all hazardous material which has leaked from a
package in a rail car or on railroad property must be carefully
removed.'' AAR states that Sec. Sec.  173.24(b)(4) and 174.57 appear to
directly contradict the TSI guidance which permits residue on the
outside of a rail car and only cautions against the presence of
excessive residue.
    AAR notes that even small amounts of molten sulfur residue can
generate significant concentrations of sulfur dioxide (SO2),
and sulfur trioxide (SO3) which are both known eye and
respiratory irritants, and hydrogen sulfide (H2S), which has
demonstrated the ability to act as a nervous system toxin. Finally, AAR
expresses concern that the presence of an ``acceptable'' level of
molten sulfur residue on the outside of the rail car may cause
emergency response actions when they are not necessary.
    PHMSA appreciates the comments received regarding this proposed
amendment. PHMSA agrees with AAR that Sec. Sec.  173.24(b)(4) and
174.57 specify that no hazardous materials residue is permitted to
adhere to the outside of a package during transport and that all
hazardous material that has leaked from a package in a rail car or on
railroad property must be carefully removed. However, PHMSA believes
that minimal levels of sulfur residue on the outside of a rail tank car
pose minimal transportation risk due to physical state, chemical
properties, and amount. PHMSA also recognizes the difficulty in
removing dried sulfur residue while in transportation.
    PHMSA does not dispute AAR's assertion that molten sulfur emits
dangerous chemicals such H2S, SO2, and
SO3. However, as noted above, the dried, fully-cooled
residue does not generate such concentrations of H2S,
SO2, and SO3 and poses little safety risk. To
this end, PHMSA considers the ``Molten Sulphur Rail Tank Car Guidance''
to be a valuable tool for instances in which a minimal amount of
residue remains on a tank car.
    AAR further comments that molten sulfur residue on the outside rail
car

may cause emergency response actions when they are not necessary.
Residue of molten sulfur could also pose a safety risk by obscuring
valuable tank car markings, labels, and stencils as well as tank car
safety appliance features, such as ladders. PHMSA believes that the
``Molten Sulphur Rail Tank Car Guidance'' provides information on when
the cleaning and removing of this residue is necessary, thus decreasing
the likelihood that the residue will obscure hazardous materials
communication or safety features or result in unnecessary emergency
response actions.
    PHMSA notes that the majority of comments for the adoption of the
``Molten Sulphur Rail Tank Car Guidance'' in the list of informational
materials not requiring incorporation by reference in Sec.  171.7(b)
were positive and believes this adoption would be beneficial to
carriers, government inspectors, and shippers. PHMSA further emphasizes
that recognition of this document would not impose any new
requirements. Instead, it would be adopted into the list of
informational materials not requiring incorporation by reference, and
therefore, would be provided for guidance purposes only. Therefore,
PHMSA is adopting these amendments to Sec. Sec.  171.7(b) and
172.102(c)(6) as proposed in the NPRM with the minor editorial changes
identified by TSI.
Hazardous Materials Table (HMT) Revisions
    The HMT in Sec.  172.101 contains information regarding the
transport conditions, proper shipping name, hazard class and division,
identification number, packing group, label codes, special provisions,
authorized expectations, non-bulk, and bulk packagings, quantity
limitations and vessel stowage requirements for hazardous materials.
Accurate information in the HMT is essential for the safe shipment of
hazardous materials by all modes.
    In the NPRM published on April 26, 2012, PHMSA proposed a number of
revisions to the Sec.  172.101 HMT, and the special provisions
specified in Sec.  172.102 to clarify the regulations, correct
inadvertent errors, and improve the accuracy of the information
contained in the HMT. The amendments to the Sec.  172.101 HMT proposed
in the April 26, 2012 NPRM included:
     Remove the Packing Group II and III entries for the proper
shipping name, ``Hydrazine dicarbonic acid diazide'' in the Sec.
172.101 HMT and clarify that Hydrazine dicarbonic acid diazide'' is
forbidden.
     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.
     Add the entries for ``Paint related material, flammable,
corrosive (including paint thinning or reducing compound)'' UN3469, PG
II, and PG III.
     Remove Special provision B72 from Column (7) for the
following entries:
    [cir] UN2484 tert-Butyl isocyanate;
    [cir] 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;
    [cir] UN3488 Toxic by inhalation liquid, flammable, corrosive,
n.o.s. with an LC50 lower than or equal to 200 ml/m3 and saturated
vapor concentration greater than or equal to 500 LC50; and
    [cir] UN3490 Toxic by inhalation liquid, water-reactive, flammable,
n.o.s. with an LC50 lower than or equal to 200 ml/m3 and saturated
vapor concentration greater than or equal to 500 LC50.
     Remove Special provision B74 from Column (7) for the
following entries:
    [cir] NA2927 Ethyl phosphonothioic dichloride, anhydrous;
    [cir] NA2845 Ethyl phosphonous dichloride, anhydrous pyrophoric
liquid;
    [cir] NA2927 Ethyl phosphorodichloridate;
    [cir] NA2845 Methyl phosphonous dichloride, pyrophoric liquid;
    [cir] UN1831 Sulfuric acid, fuming with 30 percent or more free
sulfur trioxide;
    [cir] UN3489 Toxic by inhalation liquid, flammable, corrosive,
n.o.s. with an LC50 lower than or equal to 1000 ml/m3 and saturated
vapor concentration greater than or equal to 10 LC50; and
    [cir] UN3491 Toxic by inhalation liquid, water-reactive, flammable,
n.o.s. with an LC50 lower or equal to 1000 ml/m3 and saturated vapor
concentration greater than or equal to 10 LC50.
     Revise the entries for ``Sulfur, Molten'' specified in the
Sec.  172.101 HMT to reference special provision ``R1.''
    PHMSA received nine comments on these proposed revisions.
Specifically, ACA supported the proposed addition of inadvertently
omitted entries for ``Paint related material, flammable, corrosive
(including paint thinning or reducing compound)'' UN3469, PG II, and PG
III. ACA noted it supports ``this proposed amendment and [is] pleased
to see that this correction is being addressed.''
    The eight other comments regarding these proposed revisions were
related to the proposed revision of the entries for ``Sulfur, Molten''
specified in the Sec.  172.101 HMT to reference special provision
``R1.'' Those comments are addressed above in the section entitled
Molten Sulphur Tank Rail Car Guidance Document. Based on the
aforementioned discussion, revision of the entries for ``Sulfur,
Molten'' specified in the Sec.  172.101 HMT to reference special
provision ``R1'' will be adopted in this final rule.
    PHMSA did not receive any other comments on the proposed revisions
to the Sec.  172.101 HMT as the revisions proposed in the April 26,
2012 NPRM were primarily editorial in nature or simply correcting
inadvertent errors in the HMT. Therefore, based on the above comments
and no opposition to any of the other editorial amendments, PHMSA is
adopting these amendments to the Sec.  172.101 HMT as proposed in the
NPRM.
Special Provision Revisions
    The special provisions listed in column (7) of the Sec.  172.101
HMT 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 the April 26, 2012 NPRM, PHMSA proposed revisions to
the special provisions specified in Sec.  172.102 to clarify the
regulations and correct inadvertent errors. The amendments to the
special provisions contained in Sec.  172.102 proposed in the April 26,
2012 NPRM included:
     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'', where product has spilled and dried on the exterior surface
of the tank car.
     Revise special provision 138 specified in Sec.
172.102(c)(1) 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 use the ``lead compounds, soluble n.o.s.'' entry in
the List of Marine Pollutants found in Sec.  172.101, Appendix B.
    PHMSA received nine comments on these proposed amendments. Eight of
those comments are related to the proposed addition of special
provision R1 and are addressed above in the section entitled Molten
Sulphur Tank

Rail Car Guidance Document. Based on those comments special provision
R1 specified in Sec.  172.102 will be adopted in this final rule.
    PHMSA received one comment on the proposed revision of special
provision 138 specified in Sec.  172.102. In its comment, IVODGA
supports the proposed amendment which revises special provision 138 to
clarify the solubility calculations to be used for classification and
identification of lead compounds and to harmonize the HMR provisions
with the IMDG Code SP 199. Specifically, IVODGA welcomes the
corrections to the Sec.  172.101 HMT to include the provisions of HM-
215 rulemakings which maintain alignment with the international
standards for the listed proper shipping names, hazard classes, packing
groups, special provisions, and vessel stowage requirements. PHMSA did
not receive any adverse comments to this proposed amendments, and is
adopting the revision of special provision 138 specified in Sec.
172.102 as proposed in the NPRM.
Shipping Paper Requirements for Rail Shipments of Residues
    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 authorize 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 provide 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 the NPRM published on April 26, 2012, PHMSA proposed 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 proposed 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 would harmonize 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.
    To address this issue, in the April 26, 2012 NPRM, PHMSA proposed
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.
    PHMSA received one comment on this proposed amendment. IVODGA
welcomes the amendment and notes that an equivalent international
standard of the IMDG Code Amendment 35-10, section <IP_ADDRESS>.3.2 requires
empty uncleaned packagings, IBCs, bulk containers, portable tanks, road
tank vehicles and railway tank wagons that contain the residue of
dangerous goods other than Class 7 to be described by entering the
words ``empty uncleaned'' or ``residue last contained'' before or after
the required basic description. IVOGDA acknowledges that Sec.  171.22
already authorizes the offering for transportation and transporting
hazardous materials in accordance with the IMDG Code. However, it also
notes that the inconsistency of the terminology used on shipping
documents and the sequence of information is an issue for trans-modal
shipments. To further harmonize the HMR with the UN Model Regulations
as adopted in the IMDG Code as well as other modal specific codes, in
addition to the amendments proposed in the April 26, 2012 NPRM, IVODGA
suggests that PHMSA consider revising the proposed text to permit the
use of either term ``empty uncleaned'' or ``residue last contained'' as
either option adequately communicates the hazard.
    PHMSA appreciates IVODGA's support of this amendment as well as its
clarifying suggestion with regard to the shipping paper requirements
for empty packagings. As IVOGDA correctly acknowledges, Sec.  171.22
already authorizes the offering for transportation and transporting
hazardous materials in accordance with the IMDG Code and thus the use
of the term ``empty unclean.'' As the proposals in the April 26, 2012
NPRM did not specifically address the language ``empty uncleaned'' and
the HMR currently permits the use of a shipping paper in accordance
with the IMDG code under Sec.  171.22, PHMSA will not specifically add
the term ``empty uncleaned'' to Sec. Sec.  172.203(e)(1) and
172.203(e)(2). We are, however, adopting the amendments

to Sec. Sec.  172.203(e)(1) and 172.203(e)(2) as proposed in the NPRM.
Training Record Requirements
    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
(USCG) 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, USCG 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 the NPRM published on April 26, 2012, PHMSA proposed 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.
    PHMSA received five comments on these proposed amendments to the
training record retention requirements specified in Sec.  172.704(d).
Specifically, ATA believes that the proposed record availability
provision is too broad and should be limited only to those agencies
charged with enforcing PHMSA's regulations in modal transportation. ATA
notes multiple DHS agencies have a reason to access the security plans
specified in Sec. Sec.  172.802(d) and 172.820(i)(1). However, only one
DHS agency, the USCG, has a responsibility for training records
specified in Sec.  172.704(d). As an alternative ATA suggests PHMSA
amend the proposed changes to 172.704(d) by limiting the disclosure
requirement to those agencies outside of the Department of
Transportation (DOT) that are explicitly authorized by Congress to
enforce hazmat training.
    ATA states this limitation is appropriate for many reasons. First,
it aligns authority with enforcement requirements. Only agencies with a
responsibility to enforce training compliance have any need to
determine that training requirements have been met. Other agencies
should not be tempted by the authority to audit a transporter's records
for purposes other than enforcing the HMR. Parallel to this, limiting
the disclosure of this information to as few parties as is practicable
represents proper government care for hazmat employees' personally
identifying information. Federal law mandates that agencies take care
to ensure that privacy is a paramount concern. Limiting access to only
those agencies with an explicitly granted authority to enforce the HMR
is in the spirit of such statutes.
    In addition to the comments presented by ATA, IVODGA, DGAC, COSHTA
and NTTC provided similar comments. All voiced general support for the
proposal but note the language ``an authorized official of the
Department of Homeland Security'' was too broad. IVODGA, DGAC, COSHTA,
and NTTC all suggest the language be revised to indicate the USCG as
the designated division of DHS with which training records must be
presented upon request.
    In addition to the comments above, IVODGA further asks PHMSA to
consider electronic means of recordkeeping as alternatives to hard copy
documents for the sake of time saving in producing records at the
request of a duly authorized representative of the DOT or DHS as
amended. As this proposal was not presented in the April 26, 2012 NPRM,
it is considered beyond the scope of this rulemaking and will not be
addressed in this final rule. However, it should be noted that PHMSA
currently does not prohibit the use of electronic training records as
Sec.  172.704 does not specify the manner in which records must be
maintained.
    PHMSA agrees with the concerns raised by ATA, IVODGA, DGAC, COSHTA
and NTTC regarding the availability of training records. Therefore,
based on the comments received, in this final rule PHMSA is adopting
the proposed amendments to the training record requirements specified
in Sec.  172.704(d) and will modify the text to replace the reference
to an authorized official of ``the Department of Homeland Security''
with a reference to an authorized official ``of an entity explicitly
granted authority to enforce the HMR.'' This will ensure that
appropriate agencies, including the USCG, have access to the required
training records, while limiting unnecessary review of training records
and safeguarding personally identifying

information for members of the regulated community.
Dewar Flasks Transported as Materials of Trade
    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 use 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.
    PHMSA acknowledged this requirement needs additional clarification,
as we believe that increased clarity will help to ensure the intended
application of the materials of trade exception. Therefore, in the
NPRM, PHMSA proposed 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.
    PHMSA received no comments on these proposed amendments to the
materials of trade requirements specified in Sec.  173.6(a)(2).
Therefore, we are adopting these amendments as proposed.
Lab Packs Containing Temperature-Controlled Materials
    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 further
specified in Sec.  173.12(b) of the HMR.
    On July 17, 2007, PHMSA published a request for comments regarding
the conversion of special permits into the HMR in the Federal Register
under Docket Number PHMSA-2007-27329 (HM-233A) [72 FR 388110] entitled,
``Hazardous Materials: Conversion of Special Permits into Regulations
of General Applicability.'' In response to this notice PHMSA received
comments requesting the incorporation of various special permits
including special permit DOT SP-13192. Subsequently, PHMSA published in
the Federal Register under Docket Number PHMSA-2009-27289 (HM-233A) [74
FR 68004] an NPRM entitled, ``Hazardous Materials: Incorporation of
Special Permits Into Regulations'' proposing the incorporation of
special permit DOT SP-13192. The lab pack requirements were then
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, including special permit DOT SP-13192,
were incorporated into the HMR. 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 acknowledged that this requirement needed additional
clarification, as we believe 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 the NPRM, PHMSA proposed 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). PHMSA received one comment on this
proposed amendment. Veolia commented that ``PHMSA's incorporation of
the clarification to require shippers to also comply with operational
controls for the transportation of temperature controlled materials in
Sec.  173.21(f)(1) is greatly appreciated.'' Veolia did however note
that it has additional safety concerns involving the shipment of
Division 5.2 materials under the lab pack exception stemming from the
adoption of the amendments of HM-233A that it believes PHMSA should
also address. These additional safety concerns related to the HM-233A
final rule were beyond the scope of this rulemaking and thus not
addressed in this final rule. Therefore, we are adopting as proposed
the amendment 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).
Cargo Tank Motor Vehicles Self-Closing Stop Valves
    Section 173.33 provides the requirements for hazardous materials
transported in 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, or 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 uses an
external self-closing stop valve to meet the requirements in Sec.
178.338-11(b). Therefore, in the NPRM, we proposed to revise the
provisions in Sec.  173.33(g) to clarify this exception.
    PHMSA received no comments on these proposed amendments to the
requirements for CMTV Self-Closing Stop Valves specified in Sec.
173.33(g), and are adopting these amendments as proposed.
Explosive Packaging Editorial Revision
    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.
173.62(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 the April 26, 2012 NPRM, PHMSA proposed to
revise Sec.  173.62(c)(5) packing instruction 130 to reinstate the
language inadvertently removed from the first column of packing
instruction 130.
    PHMSA received no comments on these proposed amendments to the
explosive packaging instruction 130 in Sec.  173.62(c)(5). Therefore,
we are adopting this amendment as proposed in the NPRM.
Exclusive Use Vehicles for Regulated Medical Waste (RMW)
    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 NPRM, 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.
Therefore, in the NPRM published on April 26, 2012 PHMSA proposed 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.
    PHMSA received one comment from Stericycle expressing full support
for this proposal. Stericycle did not suggest edits to the regulatory
text incorporating DOT-SP 13556. Therefore, we are adopting this
amendment as proposed in the NPRM. Furthermore, we are reinstating the
text previously adopted in the HM-218F final rule published under
Docket Number PHMSA-2009-0151 (HM-218F) [76 FR 43510] as it was
inadvertently deleted from the HMR.
    However, Stericycle did express its belief that the definition of
sharps specified in Sec.  173.134 (a)(6) should be amended to include
unbroken glass contaminated with a pathogen or that could become
contaminated with a pathogen so the regulated community has a better
understanding of the definition of sharps. Although PHMSA agrees that a
clarification of the definition of ``sharps'' may assist the regulated
community in understanding the applicable requirements, such a revision
is beyond the scope of the original proposed amendments and will not be
addressed in this final rule.
Alcoholic Beverages Exception
    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 (wine and distilled spirits as defined in 27 CFR
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. These conditions include; (1) Containing 24
percent or less alcohol by volume; (2) being packaged in an inner
packaging of 5 L (1.3 gallons) or less, and for transportation on
passenger-carrying aircraft conforming to Sec.  175.10(a)(4) as checked
or carry-on baggage; or (3) for a Packing Group III alcoholic beverage
being packaged in a packaging of 250 L (66 gallons) or less, unless
transported by air.
    Currently, the ICAO 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 Table 3-2 special provision A9 states that

alcoholic beverages containing not more than 70 percent alcohol by
volume, when packaged in receptacles of 5 liters of less are not
subject to the ICAO TI when carried as cargo. In addition, as specified
in Chapter 8; 1.1.2 paragraph (l) of the ICAO TI, alcoholic beverages
with less than 24 percent alcohol by volume or alcoholic 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.
    To address this issue, in the April 26, 2012 NPRM, PHMSA proposed
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.
    PHMSA received one comment on these proposed amendments. COSTHA
strongly supports this and other international harmonization efforts.
However, COSTHA believes the revisions to Sec.  173.150, as proposed in
the NPRM, prohibit the exception from being applied to alcohol shipped
as cargo on passenger aircraft. The proposed text in Sec.
173.150(d)(2)(iii) states alcoholic beverages transported aboard a
cargo aircraft containing more than 24 percent but less than 70 percent
alcohol by volume in an inner packaging of 5L (1.3 gallons) or less are
not subject to the requirements of Subchapter C of the HMR. COSTHA
notes that ICAO SP A9 states ``[a]lcoholic beverages containing not
more than 70 per cent alcohol by volume, when packed in receptacles of
5 litres or less, are not subject to these instructions when carried as
cargo.'' In the ICAO TI, the word `cargo' does not mean cargo aircraft,
but is defined in ICAO 3.1 as ``any property carried on an aircraft
(passenger or cargo) other than mail and accompanied or mishandled
baggage.'' Therefore in an effort to fully harmonize COSTHA recommends
PHMSA modify the language in the proposed Sec.  173.150(d)(2)(iii) to
remove the word ``cargo'' before aircraft allowing harmonization with
the ICAO TI for alcoholic beverages on aircraft, both passenger and
cargo.
    PHMSA appreciates COSTHA's comments and its general support for the
amendments. On a passenger carrying aircraft an alcoholic beverage
could be transported in three specific scenarios: (1) As carry-on
baggage, (2) in checked baggage, or (3) as cargo. The language proposed
in the NPRM addressed the first two of these transport scenarios but
neglected to account for alcoholic beverages shipped as cargo aboard a
passenger carrying aircraft. PHMSA did not intend to prohibit the
alcoholic beverage exception from being applied to alcohol being
shipped as cargo on passenger aircraft. PHMSA agrees with the statement
that ICAO SP A9 states ``[a]lcoholic beverages containing not more than
70 per cent alcohol by volume, when packed in receptacles of 5 litres
or less, are not subject to these instructions when carried as cargo''
regardless of whether it is a passenger carrying or cargo carrying
aircraft. Therefore, we are revising the proposed language in Sec.
173.150(d)(2)(iii) so that the exception for alcoholic beverages
containing more than 24% but less than 70% alcohol by volume in an
inner packaging not exceeding 5 L (1.3 gallons) may be transported as
cargo aboard both passenger and cargo aircraft. We also note that when
carried as cargo aboard a passenger carrying aircraft, the passenger
provisions of Sec.  175.10(a)(4) would no longer be applicable.
    PHMSA is confident the revised text correctly reflects all
transportation scenarios for alcoholic beverages and the exceptions
provided for both passengers transporting alcoholic beverages via
carry-on or checked baggage and transport of alcoholic beverages as
cargo via cargo and passenger aircraft. Therefore, we are adopting
these amendments as proposed in the NPRM, with the additional revision
of Sec.  173.150(d)(2)(iii).
Exceptions for Non-Spillable Batteries
    Section 173.159 specifies requirements for the transportation of
wet batteries, including non-spillable batteries. Additional 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 the NPRM published on April 26, 2012, PHMSA
proposed 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.
    PHMSA received one comment on these proposed amendments to the
exceptions for non-spillable batteries specified in Sec.
173.159a(c)(1). IVODGA welcomes the clarification of the exceptions in
Sec.  173.159a for non-spillable batteries secured to skids or pallets
which align the HMR with the requirements and exceptions within the
IMDG Code and supports the ongoing efforts to reduce frustrated
shipments in multi-modal commerce by international carriers such as the
IVODGA membership.
    However, IVODGA expresses confusion regarding the applicability of
the incident reporting requirements to a shipment of batteries that
meets the

exception provided in Sec.  173.159a(d). To alleviate this perceived
lack of clarity, IVODGA suggests PHMSA clarify the text in Sec. Sec.
173.159a(b) and 173.159a(d) to specify whether the exception from
incident reporting requirements is applicable.
    Based on the current text ``are subject to the incident reporting
requirements'' specified in Sec.  173.159a(b) it is apparent that
shipments complying with this section would be subject to the incident
reporting requirements. Furthermore, Sec.  173.159a(d) states that
``Non-spillable batteries are excepted from all other requirements of
this subchapter when offered for transportation and transported in
accordance'' with paragraph (c) and (d) of Sec.  173.159a. The term
``excepted from all other requirements of this subchapter'' is used
throughout the HMR to indicate that only the requirements of the
paragraph in which that statement is included would apply. Paragraphs
(c) and (d) of Sec.  173.159a do not mention incident reporting
requirements. Therefore, we believe it is clear that provided a
shipment of non-spillable batteries meets the requirements of Sec.
173.159a(c) and Sec.  173.159a(d), which do not include the incident
reporting requirements, it is not subject to any other requirements
contained in the HMR; therefore, we are not adopting any additional
suggested amendments to Sec.  173.159a. Based on the foregoing, PHMSA
is adopting the amendment to Sec.  173.159a(c)(1), as proposed in the
NPRM.
Cargo Tank Motor Vehicle Closures
    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).
    In the NPRM published on April 26, 2012, PHMSA proposed 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.
    PHMSA received no comments on these proposed amendments to the
closure requirements for external emergency self-closing valves on MC
338 cargo tanks specified in Sec.  177.834(j), and are adopting these
amendments as proposed.
Cargo Tank Motor Vehicle (CTMV) Recordkeeping
    Certain CTMVs require as part of their specification both a CTMV
manufacturer's data report and a certificate stating that the completed
CTMV conforms in all respects to the appropriate specification and the
American Society of Mechanical Engineers (ASME) Code. Section
178.2(c)(1) currently excepts CTMVs that require a manufacturer's data
report and certificate from the notification requirements.
Specifically, Sec.  178.2(c)(1) states that CMTV'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)(1). The current reference to
Sec.  178.345-10 in Sec.  178.2(c)(1) 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 CMTVs. In addition, we also note
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)(1).
    Therefore, in the April 26, 2012 NPRM, PHMSA proposed 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.
    PHMSA received one positive comment and no negative comments on the
proposed amendments to the recordkeeping requirements for CTMV
specified in Sec.  178.2(c)(1). DGAC supports such an amendment. This
revision will increase compliance by revising incorrect citations and
correcting unintended errors in the HMR. Therefore, we are adopting
these clarifications as proposed in the NPRM.
Flame Penetration Resistance Test
    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. The test procedure is described
in section (g)(2) of this Appendix and references a ``Figure 1,''
However, the 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.
    In the April 26, 2012 NPRM, PHMSA proposed to add Figures 1 and 2
that were referenced but inadvertently omitted from Appendix E.
    PHMSA received no comments on the proposed addition of the figures
inadvertently omitted in Appendix E to Part 178, and is adopting these
amendments as proposed in the NPRM.
Discharge System Inspection and Maintenance Program
    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 the April 26, 2012 NPRM, PHMSA proposed 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.
    PHMSA received no comments on the proposed clarification of the
discharge system inspection and maintenance program recordkeeping
requirements specified in Sec.  180.416(d), and is adopting these
amendments as proposed.

C. Comments Beyond the Scope of This Rulemaking

    In this section, PHMSA discusses the comments to the NPRM that
provided suggestions for additional revisions that were not
specifically proposed in the NPRM. Based on an assessment of the
proposed changes and the comments received, PHMSA identified four
comments that are beyond the scope of this rulemaking action.
Specifically, these comments were submitted by Stericycle, IVODGA,
Veolia, and Richard Zbilski. These comments pertain to a revision to
the definition of sharps, electronic retention of training records, the
lab pack revisions adopted into the HMR in a final rule entitled
``Hazardous Materials: Incorporation of Special Permits into
Regulations'' under PHMSA-2009-0289 [70 FR 43638] (HM-233A) and
published in the Federal Register on May 14, 2010, and the
environmental impact of fireworks.
    As these suggested amendments were not proposed in the NPRM and the
regulated community was not given the opportunity to comment on these
amendments, PHMSA is unable to address them in this final rule. If
PHMSA chooses to pursue consideration of any of these comments, we will
do so in a separate rulemaking. PHMSA appreciates Stericycle, IVODGA,
Veolia, and Richard Zbilski bringing these issues to our attention and
invites them to file petitions for rulemaking in accordance with Sec.
106.95 including all information (see Sec.  106.100) needed to support
a petition if these commenters believe these amendments warrant
rulemaking action. PHMSA briefly discusses these comments below.
Revision to the Definition of Sharps
    In the April 26, 2012 NPRM, PHMSA proposed to 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.
In addition to its comments regarding the incorporation of this special
permit DOT SP-13556, Stericycle also submitted a comment with regard to
the definition of the term ``sharps'' as specified in Sec.
173.134(a)(6). Stericycle stated that the definition of ``sharps''
should be amended to include ``unbroken glass contaminated with a
pathogen or that could become contaminated with a pathogen so the
regulated community has a better understanding of the definition of
sharps.'' Although clarification of the definition of ``sharps'' may
assist the regulated community in understanding the applicable
requirements, PHMSA has determined that such an amendment is beyond the
scope of the proposals presented in the April 26, 2012 NPRM and
therefore will not be addressed in this final rule.
Electronic Retention of Training Records
    In addition to its comments regarding the proposed revisions to the
training record requirements specified in Sec.  172.704(d), IVODGA also
requested PHMSA ``consider electronic means of recordkeeping as
alternatives to hard copy documents for the sake of time saving in
producing records at the request of a duly authorized representative.''
As this specific amendment was not proposed in the April 26, 2012 NPRM,
it is considered outside the scope of this rulemaking and will not be
addressed in this final rule. It should be noted that PHMSA currently
does not prohibit the use of electronic training records as Sec.
172.704 does not specify the manner (i.e. paper or electronic) in which
records must be kept.
Reconsideration of the Lab Pack Requirements Adopted Under HM-233A
    In addition to its comments regarding the proposed revisions to the
lab pack requirements specified in Sec.  173.12, Veolia also requested
that PHMSA reconsider amendments adopted in the HMR in a final rule
entitled ``Hazardous Materials: Incorporation of Special Permits into
Regulations'' under PHMSA-2009-0289 [75 FR 27205] (HM-233A) and
published in the Federal Register on May 14, 2010. Specifically, Veolia
requests PHMSA reconsider further amending the requirements for lab
pack to address various safety concerns it claims have resulted from
the adoption of the HM-233A final rule. Veolia is concerned that
amendments adopted in HM-233A rulemaking will diminish the safety of
the shipments of waste Division 5.2 materials for disposal by
increasing the potential for misclassification of the hazardous
materials by the shipper and allowing the use of a less rigorous
packaging. Veolia's specific comments can be reviewed in the docket for
this rulemaking. As the revisions to the lab pack requirements Veolia
references were already proposed and offered for comment in the HM-233A
NPRM and later addressed in the HM-233A final rulemaking, PHMSA does
not intend to revisit them in this final rule.
    PHMSA believes the additional comprehensive comments from Veolia
would be more appropriately addressed in a separate rulemaking specific
to lab pack requirements where they can be offered for comment from the
regulated community prior to adoption. We appreciate Veolia bringing
its safety concerns to our attention and encourage it to file a
petition for rulemaking in accordance with Sec.  106.95 including all
information (see Sec.  106.100) needed to support a petition if it
believes these amendments warrant rulemaking action.
Fireworks Containing Sulfur
    PHMSA received one comment from a concerned individual regarding
the pollution resulting from the use of fireworks. Specifically, the
commenter expresses concern about the amount and type of pollution
emitted when using fireworks. The topic of fireworks was not addressed
in the April 26, 2012 NPRM, and is therefore, beyond the scope of this
rulemaking. It should be noted that PHMSA published in the Federal
Register under Docket Number PHMSA-2010-0320 [74 FR 68004] (HM-257) an
NPRM entitled, ``Hazardous Materials: Revision to Fireworks Approvals
(RRR)'' that addresses fireworks-related issues. The docket for the
fireworks rulemaking can be found at http://www.regulations.gov under
PHMSA-2010-0320 (HM-257).

D. Provisions Not Adopted in This Final Rule and Discussion of Comments

    In this section, PHMSA discusses the changes proposed in the NPRM
and the comments received in response to the NPRM. Based on an
assessment of the proposed changes and the comments received, PHMSA
identified one provision that we are not adopting in this final rule.
Specifically, PHMSA received considerable negative comments on the
proposed revision to the closure notification requirements. Below is a
summary of the amendment proposed, the comments received, and

PHMSA's rationale for not adopting this proposed amendment.
Closure Notification Requirements
    Section 178.2 specifies the applicability of the requirements to
specification packagings and the responsibilities of the manufacturer
or other persons certifying compliance with the specification packaging
requirements of Part 178. To achieve compliance with 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 applicable 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.
    In April 2006, PHMSA received a request (Reference No.: 06-0123)
for a letter of interpretation seeking clarification of the closure
notification requirements specified in Sec.  178.2(c) for ``packages''
containing residues. This letter was submitted to PHMSA requesting
additional clarification on two previously issued letters of
interpretation (Reference Numbers 05-0015 and 05-0265) which also
addressed the topic of closure requirements with regard to
``packaging'' and ``packages.'' In response to Reference No. 06-0123,
PHMSA 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 the April 26, 2012 NPRM, PHMSA addressed this need for
clarification by proposing to revise Sec.  178.2(c) to specify that the
notification requirements apply to a packaging containing a residue of
a hazardous materials unless the packaging of hazardous materials meets
the exceptions provided in Sec.  173.29(b).
    PHMSA received seven comments on these proposed amendments from
ACA, AHS, DGAC, NACD, RIPA, USWA and Veolia. All of the comments were
extensive and strongly opposed to the amendment proposed. The
commenters addressed topics related to the proposed amendments such as
the intent and applicability of Sec.  178.2(c); impact on re-
conditioners, recyclers and re-users of packagings; information
collection burden; economic implications, and the safety benefit, or
lack thereof. PHMSA appreciates this feedback and an overview of these
comments is provided below. The complete list of comments pertaining to
this amendment is available in the docket for this rulemaking.
    Several commenters disagree with the proposed amendments to the
closure notification requirements stating that the changes did not
reflect the initial intent and applicability of Sec.  178.2(c). DGAC,
whose membership includes virtually all sectors of the hazmat
transportation industry, correctly noted that the term ``packaging'' as
defined in Sec.  171.8 and used in part 178 of the HMR refers only to
receptacles that do not contain hazardous material. Subsequently, Sec.
178.2(c) would apply to individuals moving ``packagings'' as defined in
Sec.  171.8, and not ``packages'' which would include packagings
containing hazardous materials. DGAC also states that the term
``subsequent distributors,'' as used in Sec.  178.2(c)(1), is limited
to intermediaries between the packaging manufacturer and the hazmat
offeror who fills the packaging with hazardous material. Likewise, ACA
agrees that the requirements of Sec.  178.2(c) apply to packaging
manufacturers and those who perform functions described in Part 178;
not subsequent transporters of previously filled packages.
    Another commenter, AHS, notes that the closure requirements were
originally intended to identify those tasks of a packaging manufacturer
that had not been completed by that packaging manufacturer. Therefore,
the filler would be aware that certain actions were still required to
be completed to produce, what at the time, was DOT specification
packaging (e.g. assembling and closing a knocked down fiberboard box).
Furthermore, it is AHS's understanding that the primary intent of the
requirement to ship an emptied package containing residue as if it were
still full (See Sec.  173.29) was to maintain the original hazard
communications for the residues and not for the purposes of closure
requirement notification of the packaging. AHS notes that the terms
``package'' and ``packaging'' are often incorrectly used
interchangeably and suggests that this was the case in the letter of
interpretation Reference No.: 06-0123 that precipitated the proposed
amendment.
    In addition to the concerns about the initial intent of Sec.
178.2(c), all commenters on this amendment express concern regarding
the vast impact such an amendment would have on the regulated
community, specifically re-conditioners, recyclers and re-users of
packagings. It was consistently noted that this amendment would
fundamentally change the way hazardous materials packages are
transported and have implications throughout the transportation chain.
    Many commenters had concerns about the economic impact and an
increase in information collection burden. While PHMSA originally
perceived this amendment as a simple clarification of an existing
requirement, many commenters noted that the revision would provide new
requirements and thus impose a new economic and paperwork burden. DGAC
notes that the cost of such a change would be significant and the
economic evaluation provided in the April 26, 2012 NPRM fails to
address the associated costs. Furthermore, DGAC notes this change would
require information collection as the scope of those subject to the
closure notification requirements would expand. This information
collection was not addressed in the April 26, 2012 NPRM. ACA states
this proposed requirement will add significant costs and complexity to
compliance efforts for containers that are sent for reconditioning and
reuse. AHS asks that full consideration be given to the economic and
paperwork impact of requiring every shipper and re-shipper of a filled
package to provide and retain closure instructions. NACD notes that the
operational requirements could have substantial economic impacts on
chemical distributors and customers and could:

    ``[E]asily result in tens of thousands of dollars of additional
costs for a distributor, increasing with the number of shipments.
Costs would be substantial for all distributors and would result
primarily from mailing closure instructions to hundreds of customers
and answering numerous calls for technical assistance from many of
these customers.''

    RIPA reiterates the above comments and notes that ``[r]equiring
that reconditioners be provided notifications is a costly paperwork
burden with no safety benefit of any kind.'' In addition to the cost of
the proposed amendment, many commenters were concerned that no safety
issue was identified to necessitate such a change. ACA notes

that while PHMSA indicates that this requirement will increase
compliance, there is no indication in the NPRM that there are incidents
involving container residues that stemmed from insufficient closure or
any discussion of the risk posed by residue containers. ACA concludes
that there does not appear to be a significant safety risk involved in
the movement of these types of shipments.
    AHS notes the difficulty of implementing such a requirement. It
provides an example demonstrating this difficulty by noting that for UN
4G fiberboard cartons, small UN1A2 drums, and crimped lid or friction
lid pails, there is no realistic method to re-close the outer
receptacle, or to provide inner liners, cushioning material, etc., for
a package that usually is being discarded or recycled. AHS requests
PHMSA provide incident data to ascertain whether any record of safety
problems involves emptied non-bulk packaging with closures in place but
not secured in accordance with the original packaging manufacturer's
instructions. NACD reiterates the above comments and states ``PHMSA
does not provide evidence that leaking empty containers have been a
safety problem.''
    Based on the considerable feedback and a further consideration of
the closure requirements in Sec.  178.2(c), PHMSA is not adopting the
amendment to the closure notification requirements as proposed in the
April 26, 2012 NPRM or any amendments to the closure notification
requirements.
    After further review, and as noted by numerous commenters, PHMSA
rationalizes that it is apparent that the applicability of Sec.
178.2(c) is specific to ``packagings'' and not ``packages.'' As defined
in Sec.  171.8, a packaging ``means a receptacle and any other
components or materials necessary for the receptacle to perform its
containment function in conformance with the minimum packing
requirements of this subchapter'' while a package ``means a packaging
plus its contents.'' Furthermore, as many commenters note, PHMSA agrees
that the term ``subsequent distributors'' as used in Sec.  178.2(c)(1)
is intended to address intermediaries between the manufacturer and the
hazmat offeror who fills the packaging with hazardous material. It is
apparent that the requirement to notify each person to whom the
``packaging'' is transferred is the responsibility of each subsequent
``packaging'' distributor, not each offeror of a ``package.''
    Furthermore, as is evident from PHMSA's review of the information
collection burden associated with the closure notification
requirements, the population to which this regulation is intended to
apply is restricted to packaging manufacturers and packaging
distributors and not to the entirety of shippers and offerors of
hazardous materials packages.
    Based on the comments received, PHMSA will not be adopting any
changes in the closure notification requirements specified in Sec.
178.2(c). Subsequently, closure notification requirements would not be
required to accompany a package containing a residue of a hazardous
material that is transported for the purposes of re-conditioning,
recycling or re-use. It was not PHMSA's intent to propose an amendment
that would impose a significant additional economic and information
collection burden on the regulated community. Furthermore, PHMSA did
not intend to expand the applicability of Sec.  178.2(c) beyond
``packagings'' to include ``packages.'' Rather, PHMSA's intention was
to address an issue previously identified in a letter of
interpretation. However, based on further review and the rationale
presented by commenters, we are rescinding the letter of interpretation
Reference No.: 06-0123 as the letter contains incorrect information. In
addition, PHMSA is also rescinding letters of interpretation Reference
Numbers 05-0015 and 05-0265 as they also contain misinformation.
Finally, many commenters suggest a thorough economic and safety
analysis be conducted before amendments similar to those proposed in
Sec.  178.2(c) for closure notification requirements are adopted. At
this time, PHMSA does not foresee the need for such analysis as no
amendments are being adopted.

III. Regulatory Analyses and Notices

A. Statutory/Legal Authority for This Rulemaking

    This final rule 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. This final rule makes miscellaneous amendments to
the HMR. In addition, this final rule corrects errors in the hazardous
materials table and corresponding special provisions, clarifies the
requirements for lab packing temperature controlled materials and
clarifies various cargo tank provisions and revises 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 final rule is not considered a significant regulatory action
under section 3(f) of Executive Order 12866 and was not reviewed by the
Office of Management and Budget (OMB). The final 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 rulemaking, we amend miscellaneous provisions in the HMR to
clarify the provisions and to relax overly burdensome requirements.
PHMSA anticipates the amendments contained in this rule will have
economic benefits to the regulated community. This final rule 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 final rule, 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 sulfur industry in ensuring the safe transport
of molten sulfur (P-1581). PHMSA asked for public comments based on the
proposals in the NPRM and upon receipt of public comment, PHMSA has
addressed all substantive comments in this rulemaking action.
    The amendments in the final rule promote simplification and
harmonization through interagency coordination. Specifically, in this
final rule, PHMSA is simplifying the lab pack 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 final rule 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 final rule adopts amendments that reduce the regulatory burden
on the regulated community, allows for flexibility in achieving
compliance and maintains an appropriate level of safety. This final
rule permits flexibility in achieving compliance when transporting
cargo tanks while maintaining an appropriate level of safety. This
final rule 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 adopted in this rulemaking are simple
clarifications and did not require significant scientific or
technological information. However, when necessary, 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% 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 final rule was 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.
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 that is
represented, marked, certified, or sold as qualified for use in the
transport of hazardous materials.
    This final rule concerns the classification, packaging, and
handling of hazardous materials, among other covered subjects and as
adopted preempts 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 this final rule in this matter in the Federal Register.

D. 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 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
final rule amends miscellaneous provisions in the HMR to clarify
provisions based on PHMSA's initiatives and correspondence with the
regulated community. While maintaining safety, it relaxes certain
requirements that are overly burdensome. The 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 final rule is not expected to be significant.
The

amendments 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 final
rule will not have a significant economic impact on a substantial
number of small entities.
    This final 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 final rule does not impose any new information collection
requirements and in three instances marginally decreases the
information collection burden on the regulated 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
Transportation of Dangerous Goods (TDG) 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.
     Although no new training recordkeeping requirements are
adopted in this final rule, a minimal increase in information
collection burden may be realized due to increased awareness of the
training requirements resulting from the modifications specified in
Sec.  172.704. However; in accordance with 49 U.S.C. 5107(g), training
records are exempted from the requirements of the paperwork reduction
act.

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 final 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 is adopting 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. These 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), Final Rule
    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. 5101 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.
Adopted Amendments to the HMR
    In this final rule, PHMSA is adopting amendments 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'' that was superseded by proper shipping
names adopted in a previous rulemaking.
     Add the entries for ``Paint related material, flammable,
corrosive (including paint thinning or reducing compound)'' UN3469, PG
II, and PG III to the Sec.  172.101 HMT that were inadvertently
omitted.
     Remove references to special provisions B72 and B74 in
Sec.  172.102.
     Revise special provision 138 in Sec.  172.102 to clarify
the lead solubility calculation used for classification of material as
a Marine Pollutant.
     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 of an entity explicitly granted
authority to enforce the HMR.
     Clarify that the materials 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 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 ICAO TI.
     Clarify the exceptions in Sec.  173.159a for non-spillable
batteries secured to skids or pallets.
     Revise Sec.  178.2(c) to correct incorrect regulatory
citations.
     Clarify the requirements for the Flame Penetration
Resistance test required for chemical oxygen generators and certain
compressed gases in Appendix E to Part 178.
     Clarify the inspection record requirements in Sec.
180.416 for discharge systems of cargo tanks transporting liquefied
compressed gases.
Alternatives Considered
    Alternative (1)--No action alternative: Leave the HMR as is; do not
adopt above-described amendments.
    The HMR requires various updates and clarifications to correct
certain omissions, and errors. This action also includes a few minor
modifications to existing regulatory requirements. If PHMSA chose the
no-action alternative, the public would not receive the benefit of the
various updates, clarifications, and modifications to the HMR, which
will provide information, enhance safety, and provide relief certain
unnecessary requirements. Therefore, PHMSA rejected the do-nothing
alternative.
    Alternative (2)--Preferred Alternative: Go forward with the
proposed amendments to the HMR in the NPRM, as described above.
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 human death or injury, 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.
    When developing potential regulatory requirements, PHMSA evaluates
those requirements to consider the environmental impact of each
amendment. Specifically, PHMSA evaluates the: risk of release and
resulting environmental impact; risk to human safety, including any
risk to first responders; longevity of the packaging; and if the
proposed regulation would be carried out in a defined geographic area,
the resources, especially any sensitive areas, and how they could be
impacted by any proposed regulations.
    Of the regulatory changes adopted in this rulemaking, ten have been
determined to be editorial. As such, these amendments have no impact
on: the risk of release and resulting environmental impact; human
safety; longevity of the packaging; and none of these amendments would
be carried out in a defined geographic area. These editorial amendments
are as follows:
     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'' that was superseded by proper shipping
names adopted in a previous rulemaking.
     Re-insert the entries for ``Paint related material,
flammable, corrosive (including paint thinning or reducing compound)''
UN3469, PG II, and PG III in the Sec.  172.101 HMT that were
inadvertently omitted.
     Remove references to special provisions B72 and B74 in
Sec.  172.102.
     Revise special provision 138 in Sec.  172.102 to clarify
the lead solubility calculation used for classification of material as
a Marine Pollutant.
     Correct an inadvertent deletion of the Sec.  173.62
packaging requirements for explosives.
     Clarify the exceptions in Sec.  173.159a for non-spillable
batteries secured to skids or pallets.
     Revise Sec.  178.2(c) to correct erroneous regulatory
citations.
     Clarify the requirements for the Flame Penetration
Resistance test specified for chemical oxygen generators and certain
compressed gases in Appendix E to Part 178.
     Clarify the inspection record requirements in Sec.
180.416 for discharge systems of cargo tanks transporting liquefied
compressed gases.
    The remaining non-editorial amendments are discussed in further
detail and evaluated based on their overall environmental impact as
follows:
     The requirement to permit designated agents for non-
residents to

submit designation requests by electronic mail in addition to
traditional mail does not impact positively or negatively on the risk
of release, risk to human safety, or longevity of the packaging as the
requirements of the special permit are designed to provide an
equivalent level of safety to current regulatory requirements.
Furthermore, this requirement would not be carried out in a defined
geographic area including any sensitive areas.
     The adoption of 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 makes
this document a reference material only and thus would only have a
minimal impact. Specifically, complying with this document will limit
the obstruction of valuable tank car markings, labels, and stencils as
well as tank car safety appliance features such as ladders, which may
result in a minimal positive impact with regard to the risk of release
and risk to human safety. PHMSA acknowledges that the presence of
minimal amounts of residue on the outside of a rail tank car results in
the emission of small amounts of H2S, SO2, and
SO3. However, the presence of this residue is a longstanding
occurrence related to the shipment of molten sulfur and not related to
or caused by this rulemaking. The adoption or recognition of the
``Molten Sulfphur Rail Tank Car Guidance'' document seeks to decrease
any minimal amount of risk caused by this residue. This guidance
document may also have an impact on tank car cleanliness which may
result in increased longevity of the packaging. In addition, this
guidance document could be carried out throughout the country, and is
not thought to be specific to defined geographic area that includes any
sensitive areas.
     The revision of 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 may have a minimal positive environmental
impact. This impact would result from the diminished amount of delayed
shipments between the United States and Canada and thus could diminish
the risk of release, and risk to human safety. PHMSA does not
anticipate that this amendment will affect the longevity of the
packaging.
     PHMSA does not anticipate the requirement to update the
training recordkeeping requirements in Sec.  172.704 to specify that a
hazmat employer must make hazmat employee training records available
upon request to an authorized official of the Department of
Transportation or of an entity explicitly granted authority to enforce
the HMR will have any environmental impacts. PHMSA views this amendment
as procedural and thus would have no impact on the risk of release,
risk to human safety, or longevity of the package. Furthermore, this
requirement would not be carried out in a defined geographic area
including any sensitive areas.
     The amendment to permit Division 2.1 and 2.2 gases in
Dewar flasks to use the Material of Trade exception specified in Sec.
173.6 does not provide any new regulatory requirement; it simply
clarifies PHMSA's interpretation of the applicability of the section.
Therefore, this amendment is a clarification and thus would have no
impact on the risk of release, risk to human safety, or longevity of
the package. Furthermore, this requirement would not be carried out in
a defined geographic area including any sensitive areas.
     The amendment that clarifies that temperature-controlled
materials meeting the lab pack requirements in Sec.  173.12 must also
comply with Sec.  173.21(f)(1) may have a small positive environmental
impact. Specifically, this amendment could provide valuable guidance
that could eliminate the inclusion of incompatible materials in a lab
pack and thus, lessen the risk of a release and risk to human safety.
This amendment will have no impact on the longevity of the package.
Furthermore, this requirement would not be carried out in a defined
geographic area including any sensitive areas.
     The amendment that clarifies the exceptions for external
emergency self-closing valves on 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 may
have a slight impact on the longevity of the CTMV closing valves.
Limiting the closure of these valves could eliminate some deterioration
and extend the lifespan of these CTMV valves. PHMSA also anticipates a
positive impact on risk to human safety. These valves 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). PHMSA does not anticipate any impacts on the
risk of release. Furthermore, this requirement would not be carried out
in a defined geographic area including any sensitive areas.
     The incorporation of 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 should have no
environmental impact. As special permits are designed to provide an
equivalent level of safety to current regulatory requirements PHMSA
