I. Background

    In a final rule published under Docket HM-181 (55 FR 52402, 
December 21, 1990), the Research and Special Programs Administration 
(RSPA), the predecessor agency to the Pipeline and Hazardous Materials 
Safety Administration (PHMSA), comprehensively revised the Hazardous 
Materials Regulations (HMR; 49 CFR Parts 171 to 180) to harmonize U.S. 
hazardous materials transportation requirements with the United Nations 
Recommendations on the Transport of Dangerous Goods (UN Model 
Regulations). The UN Model Regulations are not regulations, but rather 
are recommendations issued by the UN Committee of Experts on the 
Transport of Dangerous Goods (UNSCOE) and the Globally Harmonized 
System of Classification and Labeling of Chemicals (GHS). These Model 
Regulations are amended and updated biennially by the UNSCOE and serve 
as the basis for national, regional, and international modal 
regulations, including the International Maritime Organization's 
International Maritime Dangerous Goods Code (IMDG Code) and 
International Civil Aviation Organization's Technical Instructions for 
the Safe Transport of Dangerous Goods by Air (ICAO Technical 
Instructions).
    Since publication of the 1990 rule, we have issued eight additional 
international harmonization rules (Dockets HM-215A (59 FR 67390, 
December 29, 1994); HM-215B (62 FR 24690, December 16, 1996); HM-215C 
(63 FR 57929, October 29, 1998); HM-215D (66 FR 8644, February 1, 
2001); HM-215E (68 FR 1013, January 8, 2003); HM-215G (69 FR 76044, 
December 20, 2004); HM-215I (71 FR 78596, December 29, 2006); and HM-
215J (74 FR 2200, January 14, 2009)) based on the corresponding 
biennial updates of the UN Model Regulations, the IMDG Code, and the 
ICAO Technical Instructions.
    To maintain alignment of the HMR with international requirements, 
in this final rule, we are incorporating changes based on the sixteenth 
revised edition of the UN Model Regulations, Amendment 35-10 to the 
IMDG Code, and the 2011-2012 ICAO TI, which becomes effective January 
1, 2011 (the IMDG Code is effective January 1, 2012).
    Federal law and policy strongly favor the harmonization of domestic 
and international standards for hazardous materials transportation. The 
Federal hazardous materials transportation law (Federal hazmat law; 49 
U.S.C. 5101 et seq.) permits PHMSA to depart from international 
standards in order to promote safety or other overriding public 
interest, but otherwise requires PHMSA to align the HMR with 
international transport standards and requirements to the extent 
practicable (see 49 U.S.C. 5120). Harmonization enhances international 
trade by minimizing the costs and other burdens of complying with 
multiple or inconsistent safety requirements for transportation of 
hazardous materials to and from the United States. This becomes 
increasingly important as the volume of international hazardous 
materials shipments grows. Harmonization also enhances safety for 
international movements, but only if the international standards 
themselves provide an appropriate level of safety. PHMSA actively 
participates in the development of international standards for the 
transportation of hazardous materials, frequently advocating the 
adoption in international standards of particular HMR requirements.
    When considering the adoption of international standards under the 
HMR, we review and evaluate each amendment on its own merit, on the 
basis of its overall impact on transportation safety, and the economic 
implications associated with its adoption into the HMR. Our goal is to 
harmonize without diminishing the level of safety currently provided by 
the HMR and not impose undue burdens on the regulated public.

II. Primary Topics of Concern Discussed in the ANPRM

    PHMSA published an advance notice of proposed rulemaking (ANPRM) 
(74

[[Page 3309]]

FR 53982, October 21, 2009) highlighting issues under consideration for 
harmonization with international standards and requesting comments as 
to whether the HMR should be amended to incorporate specific 
international standards and the potential benefits and costs of doing 
so.
    Comments on specific harmonization issues covered in the ANPRM are 
discussed in brief below. Please review the notice of proposed 
rulemaking (NPRM) (75 FR 52070, August 24, 2010) for a complete 
discussion of comments to the ANPRM.

A. Limited Quantities and Consumer Commodities

    PHMSA has long recognized the need to authorize limited exceptions 
for the transportation of classes and quantities of hazardous materials 
described as limited quantities, or consumer commodities reclassed as 
ORM-D. Considerable efforts have been made internationally to harmonize 
multi-modal standards with regard to the transport of limited 
quantities, including consumer commodities. PHMSA held public meetings 
on this issue in February 2006 and March 2008 to discuss potential 
impacts on domestic stakeholders. Additionally, this issue was 
discussed during the agency's pre-UN public meetings held in 2006 and 
2007. There was considerable domestic interest in pursuing further 
harmonization internationally due to the potential for substantial 
savings in transportation costs and improved transportation efficiency. 
In the ANPRM (74 FR 53982, October 21, 2009), PHMSA invited comments on 
this issue with regard to aligning the HMR with the UN Model 
Regulations for the domestic and international transport of limited 
quantities and consumer commodities. Of particular concern was any 
potential negative impact on domestic transportation through the 
elimination of the transportation mechanism for limited quantity 
hazardous materials reclassed as ORM-D. While some changes adopted in 
the UN Model Regulations are similar to provisions currently in the HMR 
(e.g., inner packaging limits and authorized use of non-specification 
outer packagings), some changes are not (e.g., marking and labeling). 
In the ANPRM, PHMSA suggested that, depending on comments received and 
our own evaluation, the agency may determine that the significance of 
any amendments on this issue may warrant a separate rulemaking action.
    We received several comments submitted in response to the ANPRM 
supporting adoption of the UN Model Regulation limited quantity 
provisions into the HMR. The commenters urged PHMSA to move forward and 
adopt the limited quantity provisions as prescribed in the sixteenth 
revised edition of the UN Model Regulations. However, several 
commenters expressed concern that this should not be done at the 
expense of the ORM-D provisions currently in the HMR. Some altogether 
opposed the elimination of the existing provisions for ORM-D materials 
as part of HM-215K and recommended that any changes to the requirements 
be made through a separate rulemaking.
    In the NPRM (75 FR 52070, August 24, 2010), PHMSA outlined its 
determination, partially based on our perception of favorable comments 
received in response to the ANPRM, that aligning the existing limited 
quantity provisions in the HMR with the international standards and 
regulations (i.e., UN Model Regulations, IMDG Code and the ICAO TI) 
would enhance safety by facilitating a single, uniform system of 
transporting limited quantity materials. We emphasized the proposals 
did not include the immediate or short-term removal of the existing 
provisions in the HMR for limited quantities reclassed as ORM-D 
(including those for consumer commodities, cartridges, small arms and 
cartridges, power device) and included a delayed compliance period we 
believed was sufficient in length to allow stakeholders time to comply 
with the transition to the revised limited quantity requirements and 
eventual elimination of the ORM-D classification. Because the limited 
quantity provisions in the UN Model Regulations and the IMDG Code are 
closely aligned with those already contained in the HMR, we contended 
that domestic alignment for highway, rail and vessel transportation 
would result in minimal impact and regulatory burden. And, because of 
the inherent risk unique to air transportation, we believed full 
harmonization with the ICAO TI (where appropriate) was necessary with 
regard to the materials authorized and quantity limits for limited 
quantities (including consumer commodities) intended for transport by 
air.

B. Classification of Division 1.4S Explosives

    For eight Division 1.4 explosive articles (UN0323, UN0366, UN0441, 
UN0445, UN0455, UN0456, UN0460, and UN0500), the UN Model Regulations 
have been amended to require a Type 6(d) test to determine whether such 
articles may be assigned to Compatibility Group S. Assignment to 
Compatibility Group S indicates that hazardous effects from accidental 
functioning are limited to the extent the article or substance does not 
significantly hinder or prohibit fire fighting or emergency response 
efforts in the immediate vicinity of a package containing the material. 
The test is designed to be performed on a single package containing an 
explosive article or explosive substance to determine if the package is 
capable of containing any hazardous effects in the event of an 
accidental functioning of its contents. The amendment is supplemented 
by revisions to the explosives testing standards in the UN Manual of 
Tests and Criteria as well as the adoption of a new special provision 
that would authorize the use of the above mentioned identification 
numbers only if the results of the Type 6(d) test successfully 
demonstrate that any hazardous effects are confined within a package. 
In the ANPRM, we invited commenters to provide data and information 
concerning the possible safety impacts of the new test provisions and 
compliance costs that would be incurred if the new test were adopted 
into the HMR. In addition, we invited commenters to provide suggestions 
or recommendations concerning whether to apply the test to already-
approved explosives.
    We received several comments both supporting and opposing adoption 
of the Type 6(d) test to determine whether a Division 1.4 explosive 
article may be assigned to Compatibility Group S. All the commenters 
who addressed this issue indicated that, if adopted, the test must be 
applied to previously-approved articles in a manner that is reasonable 
and not overly broad. One suggestion was to allow the classification of 
previously-approved explosive articles to be based on results of 
testing of product groups by a PHMSA-approved laboratory or on results 
of self-testing and video documentation by the manufacturer.
    Commenters opposing adoption of the Type 6(d) test suggested that 
more research on the practical effect of this testing requirement is 
necessary and that the lack of grandfathering criteria for products 
already approved as Division 1.4S explosives (e.g., power device 
cartridges) is impractical, expensive, and impedes commerce. They also 
indicated concern regarding the cost of articles consumed in testing in 
addition to the cost of pre-testing or redesign of an article by a 
manufacturer to ensure passing the Type 6(d) test, but did not quantify 
these costs.

C. Classification of Sour Crude Oil

    Currently, all types of petroleum crude oil are listed as a Class 3 
flammable liquid in the Sec.  172.101 Hazardous Materials Table (HMT). 
PHMSA is aware that transportation of a certain type of crude oil known 
as ``sour'' crude oil may pose risks not associated with other types of 
crude oil due to its inherent potential of evolving hydrogen sulfide, a 
highly toxic and flammable gas. Sour crude oil, commonly found in North 
America, contains a high concentration of sulfur. The evolution of 
hydrogen sulfide vapors from crude oil is dependent on temperature, 
packaging confinement, transport conditions (e.g., sloshing), bacteria, 
and sulfur concentration, among many other potential factors. When 
transported in bulk packagings such as cargo tanks or tank cars, the 
evolved hydrogen sulfide gas may build up in the vapor space of the 
packaging, posing a potential risk, particularly during loading and 
unloading.
    Based on the risk of toxic vapors, the UN Model Regulations were 
amended by assigning a new identification number and shipping 
description for sour crude oil with a flammable primary hazard and a 
toxic subsidiary hazard. Additionally, a new special provision was 
added specifying the assignment of a Packing Group (PG) based on the 
degree of danger presented by either the flammability or toxicity 
hazard of the sour crude oil. For example, sour crude oil meeting 
flammability criteria for Class 3, PG II, and toxicity criteria for 
Division 6.1, PG I, poisonous-by-inhalation, would be classified as a 
Class 3, PG I material.
    In the ANPRM, PHMSA invited commenters to provide data and 
information concerning the impact on domestic shippers and carriers if 
these requirements were adopted in the HMR. The agency also asked for 
comments addressing which hazard communication methods (e.g., package 
markings, shipping papers) and/or packaging requirements are most cost-
effective for communicating the hazards and reducing the risks of 
transporting sour crude oil.
    We received comments opposing adoption of the UN amendments for the 
description and classification of sour crude oil into the HMR. The 
commenters recommended against requiring domestic use of the new proper 
shipping name for sour crude oil with a Division 6.1 subsidiary risk 
and recommended that use be limited to international transport. 
Commenters further recommended that PHMSA should require drivers 
engaged in the loading and unloading of sour crude oil to wear a 
hydrogen sulfide monitoring device and have respiratory protection 
accessible, and require warning signs at the cargo tank manhole and 
area of operation. Additionally, commenters recognized that hydrogen 
sulfide gas is a hazard, but suggested that classification of crude oil 
at the time of shipment may not reflect the toxicity of hydrogen 
sulfide in the vapor space of a cargo tank or other packaging after the 
crude oil has been in transportation. They also noted that there are 
best industry practices already in place that address this issue and 
that the Occupational Safety and Health Administration (OSHA) has 
requirements in place to communicate the hazards of hydrogen sulfide in 
the workplace. They supported other means of hazard communication to 
ensure that workers are aware of the hazards of hydrogen sulfide such 
as a marking on a bulk packaging.

D. IBC Rebottling

    Under both the UN Model Regulations and the HMR, replacement of the 
rigid plastic receptacle of a composite IBC is considered a ``repair'' 
under certain conditions and, thus not subject to design qualification 
testing as a new or different design. The UN Model Regulations were 
amended to specify that a replacement bottle (i.e., rigid plastic 
receptacle) must be of the original tested design type and limits the 
replacement to a bottle from the original manufacturer. In the ANPRM, 
we invited comments on this amendment and how, if adopted into the HMR, 
it would impact the use of IBCs in domestic or international commerce.
    All commenters who addressed this issue supported the adoption of 
the UN Model Regulations definition of ``repair'' for IBC rebottling 
purposes. The comments included a request for an extended compliance 
date of January 1, 2012 to provide users and manufacturers of composite 
IBCs adequate time to implement the provision and not place them at an 
economic disadvantage with international counterparts.

E. Metal Hydride Storage Systems in Conveyances

    A metal hydride storage system is a single complete hydrogen 
storage system that includes a receptacle, metal hydride, a pressure 
relief device, a shut-off valve, service equipment, and internal 
components. The HMR currently do not prescribe specific packaging or 
shipping methods for metal hydride storage systems containing hydrogen. 
However, PHMSA has issued a number of special permits to allow the use 
of these systems for transport. The UN Model Regulations, in new 
Packing Instruction P205, prescribe standards for the construction, 
qualification, marking and requalification of such systems. In the 
ANPRM, PHMSA invited comments on whether similar standards should be 
adopted into the HMR. One commenter supported adoption of the standards 
for the construction, qualification, marking, and requalification of 
metal hydride storage systems containing hydrogen.

F. In Vitro Testing for Corrosivity

    In 1993, RSPA began recognizing an alternative test method (i.e., 
in vitro testing commercially available as Corrositex[reg]), which is 
not carried out in live animals, to determine the corrosivity of a 
hazardous material for transportation purposes under the terms and 
conditions specified in a special permit (DOT-SP 10904). Similar in 
vitro test methods are prescribed in the following Organization for 
Economic Cooperation and Development (OECD) Guidelines for the Testing 
of Chemicals and were adopted in the UN Model Regulations:
     No. 430, ``In Vitro Skin Corrosion: Transcutaneous 
Electrical Resistance Test (TER)'' (2004);
     No. 431, ``In Vitro Skin Corrosion: Human Skin Model 
Test'' (2004); and,
     No. 435, ``In Vitro Membrane Barrier Test Method for Skin 
Corrosion'' (2006).
    Because methods 430 and 431 can be used to determine corrosivity 
for other than transportation purposes, they cannot be used to 
determine the Packing Group (PG) assignment of a material that tests 
positive for corrosivity for the purposes of hazardous materials 
transportation. A negative result for corrosivity under methods 430 and 
431 can, however, preclude further testing to determine PG assignment 
using method 404, the current OECD Guideline involving in vivo testing 
or method 435, the newly adopted OECD Guideline involving in vitro 
testing.
    All commenters responding to the ANPRM supported adoption and use 
of the OECD in vitro test methods for determining corrosivity on the 
basis of reducing the number of tests requiring live animals.

III. Comments Submitted in Response to Noteworthy Harmonization 
Amendments Proposed in the August 24, 2010 NPRM; the Final Rule

    In our latest harmonization effort, we received over 2,200 comments 
in response to the NPRM (75 FR 52070, August 24, 2010). The majority of 
the

[[Page 3311]]

comments received were from individuals in support of adoption of 
corrosivity testing methods not based on the results of live animal 
testing. The following individuals, companies, and organizations 
submitted comments to the NPRM (in chronological order of submittal).

A. Harmonization Amendments Adopted in This Final Rule

    In this final rule, PHMSA is adopting the following amendments to 
harmonize the HMR with the most recent revisions to the UN Model 
Regulations, ICAO Technical Instructions, and the IMDG Code:
1. Petitions for Rulemaking
    We are addressing one petition for rulemaking, P-1550, from PETA 
requesting that PHMSA incorporate by reference OECD Guidelines 430, 431 
and 435 into the HMR that prescribe in vitro testing methods for 
determining corrosivity.
2. Hazardous Materials Table (HMT)
    Amendments to the HMT to add, revise, or remove certain proper 
shipping names, hazard classes, packing groups, special provisions, 
packaging authorizations, bulk packaging requirements, passenger and 
cargo aircraft maximum quantity limitations, and vessel stowage 
provisions.
3. Organic Peroxide Tables
    Amendments to the Organic Peroxide Tables to add, revise, or remove 
certain hazardous materials and provisions.
4. Incorporation by Reference
    Amendments to incorporate by reference the 2011-2012 ICAO Technical 
Instructions, Amendment 35-10 to the IMDG Code, sixteenth revised 
edition of the UN Model Regulations and the fifth revised edition of 
the UN Manual of Tests and Criteria. Additionally, we are updating our 
incorporation by reference of the Canadian Transportation of Dangerous 
Goods Regulations to include Amendment 6 (SOR/2008-34) February 7, 2008 
(pertains to miscellaneous amendments); and Amendment 7 (SOR/2007-179) 
August 22, 2007 (pertains to highway cargo tanks). This incorporation 
by reference augments the broad reciprocity provided in Sec.  171.12 
where the HMR allow the use of the Canadian TDG Regulations under 
certain conditions when transporting hazardous materials to or from 
Canada by highway or rail.
5. Limited Quantities
    We received a number of comments in response to the limited 
quantity and ORM-D classification amendments proposed in the August 
2010 NPRM. Commenters can basically be categorized into two groups: 
Those supporting harmonization with the international standards and 
regulations for limited quantities and those in opposition to the 
eventual elimination of the ORM-D classification. The remainder of the 
commenters offered suggestions or revisions to clarify or aid 
understanding of the proposed amendments.
    Those commenters generally supporting harmonization of the limited 
quantity provisions include:

Alaska Airlines;
American Coatings Association;
American Trucking Associations;
Association of Hazmat Shipper, Inc.;
Council on Safe Transportation of Hazardous Articles, Inc.;
Dangerous Goods Advisory Council;
FedEx Express;
International Vessel Operators Dangerous Goods Association;
PPG Industries, Inc.;
Sporting Arms and Ammunition Manufacturers Institute, Inc.; and
United Parcel Service.

Those commenters opposing the eventual elimination of the ORM-D hazard 
classification include:

American Coatings Association;
Aviation Suppliers Association;
Healthcare Distribution Management Association;
Modification and Replacement Parts Association;
PPG Industries, Inc.;
Safety Specialists, Inc.;
Utility Solid Waste Activities Group; and
Valspar.

    Due to the large number of commenters and the variety of comments 
provided, we outline pertinent topic areas to better address all the 
comments. The comments are discussed and addressed as follows:
    a. Air-specific requirements. In the NPRM, we proposed to revise 
Sec.  173.27 to add a new table outlining air transport requirements 
for limited quantity material including package quantity limits 
consistent with the ICAO Technical Instructions. The proposed quantity 
limits for air transport differ from the quantity limits for other 
modes, which was a point of contention for some commenters. Three 
commenters (ACA, DGAC, SSI) disagreed with the adoption of the proposed 
package limits in the table and one commenter (COSTHA) expressed 
concern that the table is too broad. ACA asserted:

[[Page 3312]]

    Introducing these limits will only frustrate domestic 
transportation and introduce unnecessary complexity into a fairly 
simple process. In the coatings industry, air shipments are not the 
norm and are only used when there is some urgency or the destination 
is a remote location. Requiring different inner and outer packaging 
quantity limits for air will eliminate the efficiency of a ``one 
size fits all LQ shipments'' process.

    SSI added:

    Some materials that were ORM-D may not be eligible to be shipped 
as limited quantity. Most inner packagings have been severely 
reduced. Isopropanol UN1219 (rubbing alcohol) can be presently 
shipped in inner containers up to 1 liter. Under the new Table 3 the 
inner container is reduced to 500 milliliter. This product is 
normally sold in pints, quarts, and gallons. Quarts would not be 
eligible for limited quantity air shipments. This will require 
shippers to ship in UN standard packaging, apply hazard class labels 
and meet all other requirements for fully regulated shipments.

    We understand that more inner packagings may be required of a 
material authorized to be shipped as a limited quantity by air. SSI 
used Isopropanol as an example in their comments where the inner 
packaging quantity limits are reduced from 1 liter to 500 milliliters 
for a Packing Group II Class 3 (flammable liquid) when the current 
limits of the HMR are compared with the ICAO Technical Instructions. 
SSI also stated that the product is sold in pints, quarts and gallons. 
Currently under the HMR, the gallon is ineligible as a limited 
quantity. Under the amendment proposed in the NPRM, the gallon and 
quart would be ineligible for air transport as a limited quantity. 
However, because the outer packaging quantity limit is 1 liter for a 
Packing Group II Class 3 (flammable liquid), SSI would just have to 
substitute 2 one-pint inner packagings for a one-quart container of 
product in the same package.
    DGAC reasoned:

    The HMR limited quantity provisions predate ICAO TI limited 
quantity provisions. When limited quantity provisions were 
introduced in the ICAO TI * * * on the basis of existing U.S. 
limited quantity provisions, additional limitations were included * 
* * RSPA and PHMSA have, up until now, not deemed it necessary to 
incorporate these limitations in the HMR. The long intervening 
period between when the limits were first introduced in the ICAO TI 
and the present suggests that it is unnecessary to adopt these 
limits for the sake of harmonization. Further, [we are] unaware of 
any new safety information that would justify introducing these 
limits at this time.

    DGAC further argued:

    Introducing these limits will serve to frustrate domestic 
transportation. A key objective of * * * PHMSA has been to provide 
multimodal harmonization * * * so that the same package will 
essentially be suitable by all modes of transportation. This is 
currently true for limited quantity packages * * * By introducing 
new limits, as shown in the table referenced by proposed Sec.  
173.27(f), limited quantity packages prepared for ground or sea 
transport may not necessarily be suitable for air transport. Most 
shippers commonly transport * * * limited quantity packages by modes 
other than air. Currently, with limited quantity package 
requirements for all modes closely aligned, transporting a limited 
quantity package is relatively straightforward. If the limitations 
on inner and outer package quantity limits and new performance 
requirements are introduced * * * it may be necessary to repackage 
ground/sea limited quantity packages for purposes of air transport. 
[We] are unaware of any safety concerns that would justify the 
imposition of these new limitations.

    Major differences already exist under the HMR for the air transport 
of limited quantities as compared to other modes. For example, limited 
quantity and consumer commodity inner packagings containing liquids are 
subject to the pressure differential capability requirements in Sec.  
173.27(c).
    COSTHA explained further confusion:

    It is important for shippers to use the Sec.  172.101 Table to 
determine eligibility for a limited quantity * * * However, if one 
uses only Table 3, the shipper may inappropriately determine that a 
material is eligible for shipment as a limited quantity. For 
example, [c]hlorosilanes are not permitted to be packaged in 
accordance with limited quantity provisions * * * however, [certain 
classes of PG II materials] (many chlorosilanes fall into these 
classes) are identified as having acceptable limits * * * according 
to the Sec.  173.27 Table 3. Given that limited quantities is a 
source of confusion for many shippers and carriers, this table does 
less to clarify a point and more to confuse the reader.

    Section 173.27(f) clearly states that, for transportation by 
aircraft, materials packaged as limited quantities must be eligible for 
transportation aboard a passenger-carrying aircraft. In this final 
rule, we are adding additional clarification in Sec.  173.27(f) to 
emphasize this critical step in determining limited quantity 
eligibility by also referring the reader to Column (9A) of the HMT. As 
stated in the NPRM, PHMSA is studying the feasibility of revising the 
HMT to further assist in determining limited quantity eligibility by 
air or possibly by all modes of transportation.
    Two commenters (ASA, MARPA) were critical of the nature of proposed 
regulatory changes without an apparent safety need, specifically with 
regard to the limited quantity marking for air transport consistent 
with the ICAO Technical Instructions. The commenters argued that the 
constant changes make compliance with the regulations difficult. ASA 
and MARPA stated:

    The 2009-2010 [ICAO TI] authorized * * * the UN identification 
number in a diamond shape [as] the mandatory way to mark limited 
quantity packages starting in 2011 * * * Beginning in 2011, ICAO has 
abandoned the marking protocols announced in 2009, and established a 
new, different identification protocol for identifying limited 
quantities * * * Instead of placing the UN identification number in 
the diamond shape, shippers will be required to place a ``Y'' in the 
diamond shape * * * There appears to be no reason other than mere 
harmonization for the sake of harmonization for adopting the ICAO 
limited quantity marking. [The] marking provides no additional value 
* * * because many people in the United States system will have no 
idea what the ``Y'' marking means * * * Although ``Y'' is the letter 
that precedes limited quantity packing instructions in the ICAO 
system, the letter ``Y'' has no special meaning in the existing 
United States Regulations.

    b. Dual marking system. Support for harmonization efforts including 
the adoption of the square-on-point limited quantity marking (i.e., the 
square-on-point with top and bottom portions black and the center 
white) generally coincided with support for the eventual elimination of 
the ORM-D classification along with the ORM-D marking. The basis for 
support was that this would eliminate a dual system of marking packages 
for domestic and international transportation. With regard to 
elimination of a dual marking system, some commenters (AA, FedEx, 
IVOGDA) indicated that a dual system of marking creates confusion and 
requires carriers and shippers to adjust their training programs to 
account for this dual system. They therefore recommend PHMSA consider 
an earlier implementation date than the proposed January 1, 2013 date. 
AA added:

    We encounter almost every day reused boxes in the U.S. mail, 
passenger baggage, or cargo shipments that have old ORM-D marks. 
This takes considerable time to inspect and causes frustration to 
the public when non-hazardous shipments are denied transportation 
because of a marking they do not understand as an indication of 
hazardous materials.

    PHMSA notes that adoption of a new limited quantity marking(s) may 
not necessarily alleviate or eliminate use of packaging premarked with 
the limited quantity square-on-point for non-hazardous materials.
    Notwithstanding the general comments regarding dual marking, 
several commenters offered suggestions or revisions to improve or 
clarify the proposed requirements. As part of the NPRM, we authorized 
voluntary use of

[[Page 3313]]

the limited quantity marking. UPS urged PHMSA to delay voluntary use to 
allow carriers time to develop appropriate training in response to a 
final rule, stating that:

    In [our] experience, this kind of authorization * * * can lead 
to practical difficulties which in turn could have compliance and 
safety implications * * * Training in UPS will be needed to educate 
U.S. package handlers of the meaning of the limited quantity 
marking.

    Additionally, on the basis of their opposition to adoption of the 
air transport requirements for limited quantities consistent with the 
ICAO TI, DGAC recommended that:

    The ``Y'' package mark [proposed] in Sec.  172.315 not be 
required * * * [and] recommend that [PHMSA] allow permissive use of 
the ``Y'' mark for all modes of transport when the package meets the 
relevant requirements of the ICAO TI.

    We agree with the DGAC recommendation that a ``Y'' marked package 
in full conformance with the air transport requirements for a limited 
quantity package should be authorized transportation by all modes and 
are revising Sec.  171.22 accordingly. However, we do not agree with 
their suggestion that the limited quantity ``Y'' mark be voluntary. 
There are currently two different ways to mark a package of limited 
quantities in the HMR and a third (four if counting packaged ORM-D-AIR 
materials) would be very disruptive. Therefore, in this final rule, 
PHMSA is adopting the ``Y'' mark as proposed and providing a transition 
period to allow for the continued use of existing markings until 
January 1, 2012.
    c. Elimination of the ORM-D class. Most commenters opposing the 
elimination of the ORM-D classification recommend using a separate 
rulemaking to implement this proposal. Some question whether the costs 
of eliminating this classification have been fully considered; others 
question whether there is sufficient safety justification to warrant 
replacing the current domestic ORM-D provisions with internationally 
harmonized provisions. A sampling of comments received follows. ACA 
argued:

    Although [we] supported harmonization of the limited quantities 
exceptions at the UN discussions, [there was an] understanding that 
the consumer commodity exception was a separate issue * * * In the 
coatings and adhesives industry, we are unaware of any major 
incidents with consumer commodity shipments. While PHMSA indicates 
that ``aligning the existing limited quantity provisions in the HMR 
with the international standards will substantially enhance 
safety,'' we question how this applies to the proposal to eliminate 
ORM-D consumer commodities.

    Valspar asserted:

    We believe PHMSA has overreached the HM-215 harmonization 
process by proposing * * * to eliminate the well-defined ORM-D 
(Consumer Commodity) hazard class. We believe any proposal * * * 
should not be linked to the international harmonization program. In 
several industry/regulatory conferences it has been proposed that 
Limited Quantity and Consumer Commodity are synonymous. We do not 
agree with this premise and strive to ensure that our ``Consumer 
Commodities'' meet the spirit and HMR definition of ``* * * intended 
or suitable for sale through retail sales agencies or 
instrumentalities for consumption by individuals for purposes of 
personal care or household use.'' [We ship] many items under Limited 
Quantity provisions that we do not believe meet the ``suitability'' 
test and assert there is an important distinction between the two. 
We applaud PHMSA for clearly defining the pathway to ORM-D through 
Limited Quantity and Special Provision options and can only imagine 
whether this can be misused through other less clear regulation * * 
* We challenge PHMSA to revisit the assertion to Executive Order 
12866 cited in the HM-215K NPRM that only considers the listed 
harmonization to be beneficial, with no acknowledgement of the 
financial cost to ORM-D shippers.

    DGAC expressed concern that:

    Eliminating the ORM-D classification and package marking [will 
make it] that such packages will no longer be excepted from the 
Sec.  175.75 requirements for air transport. No similar requirement 
applies under the ICAO TI so * * * this change cannot be justified 
on the basis of harmonization * * * [We believe] PHMSA considers 
limited quantity packages and currently classified ORM-D packages as 
posing comparable hazard[s]. Consistent with that approach, we 
recommend that PHMSA similarly except all limited quantity packages 
from the Sec.  175.75 requirements.

    We agree with DGAC regarding Sec.  175.75 quantity limits for 
limited quantity packages and are revising the section accordingly. 
Limited quantity shipments will enjoy the same exception from the Sec.  
175.75 quantity limits as ORM-D-AIR materials currently receive.
    USWAG stated:

    We believe elimination of the ORM-D standards for transportation 
* * * will disrupt longstanding shipping practices while failing to 
provide commensurate safety benefits.

    The commenter also expressed concern for downstream shippers who 
have received ORM-D packages but can no longer transport this package 
beginning on the January 1, 2014 proposed compliance date. USWAG 
encouraged PHMSA to implement a phased-in approach that would authorize 
downstream shippers (that do not repackage these materials) to use ORM-
D provisions for an additional period of time.
    One commenter (HDMA) provided information that the proposal as 
written would impose significant cost on the domestic transport of 
medicines and other healthcare or consumer products. HDMA members 
concluded that compliance with the regulations would require 
replacement of more than 10 million plastic totes embossed with the 
ORM-D marking, costing members an estimated $70 million to purchase new 
totes with the new limited quantity marking. HDMA is prepared to phase 
out the use of totes with the ORM-D marking but believes this should be 
done over an extended period of time to enable existing totes embossed 
with the marking to be used over their lifetime. HDMA stated:

    PHMSA may not have recognized that some industries rely on 
containers that are embossed with the transport mark and hence 
conversion to a new mark is considerably more complicated than 
simply changing a label.

    Just as PHMSA has done in the past, if there is merit to a 
particular segment of the regulated community requiring a longer 
transition period to be considered, it shall be observed on a case-by-
case basis. In their comments, HDMA did not indicate what a ``normal'' 
lifetime would be. In their defense, however, they provided comments 
that were quantified and directly related to their concerns about the 
regulatory and economic burden placed upon their particular industry.
    Finally, several commenters (e.g., COSTHA, FedEx) noted concern 
over use of the ORM-D mark after the transition period ends (i.e., 
beginning January 1, 2014). The commenters recommend that PHMSA clarify 
that at the end of the transition period, a package marked with the 
ORM-D mark will no longer indicate that a packaging contains a 
hazardous material (i.e., a consumer commodity).
    d. Conclusion. In the August 2010 NPRM, PHMSA outlined our 
determination, partially based on our perception of favorable comments 
received in response to the ANPRM, that aligning the existing limited 
quantity provisions in the HMR with the international standards and 
regulations (i.e., UN Model Regulations, IMDG Code and the ICAO TI) 
would enhance safety by facilitating a single, uniform system of 
transporting limited quantity materials. We emphasized the proposals 
did not include the immediate or short-term removal of the existing 
provisions in the HMR for limited quantities reclassed as ORM-D 
(including those

[[Page 3314]]

for consumer commodities, cartridges, small arms and cartridges, power 
device) and included a delayed compliance period we believed was 
sufficient in length to allow stakeholders time to comply with the 
transition to the revised limited quantity requirements and eventual 
elimination of the ORM-D classification.
    Based on careful consideration of the comments received in response 
to the proposals made in the NPRM, PHMSA is moving forward with a 
substantially revised final rule that adopts the new limited quantity 
provisions and the eventual phase-out of the ORM-D hazard class. This 
will implement a standardized system for national and international 
multimodal transportation. The approach of deminimis quantities, 
excepted quantities, limited quantities and consumer commodities will 
all have the same provisions and requirements for international and 
national transportation in a system that will promote compliance, 
efficiency and consistent training and lower costs after 
implementation.
6. Classification of Certain Division 1.4S Explosives
    In the August 24, 2010 NPRM, PHMSA stated it understood commenter 
concerns that prescribing additional tests usually results in increased 
research and development costs. PHMSA also acknowledged that it 
believed there was merit to additional prescribed tests when they 
result in a credible and measureable increase in safety. Consequently, 
in the NPRM we proposed to require the phased-in testing of all new and 
previously approved Division 1.4S explosives articles and substances, 
depending on the intended mode of transport. For newly produced 
explosive articles, a person who successfully performs the Type 6(d) 
test would not be required to also perform the Type 6(a) test. PHMSA 
believes such initiatives will greatly reduce research and development 
costs without compromising safety.
    In the NPRM, PHMSA proposed to adopt the requirement for the Type 
6(d) test as prescribed in Section 16.7 of the fifth revised edition of 
the UN Manual of Tests and Criteria in the new Sec.  172.102(c)(1), 
special provision 347. For affected articles (or substances) intended 
for transportation by aircraft, the proposed compliance date of this 
new requirement was April 1, 2011. If a manufacturer or approval holder 
of affected articles that previously classed and approved an article as 
Division 1.4S chooses to continue offering such shipments by aircraft, 
we proposed the articles must be successfully tested under Test Series 
6(d) and a new approval be obtained from PHMSA. Additionally, we 
proposed that a previously classed and approved Division 1.4S article 
that is not successfully tested under Test Series 6(d) must be assigned 
to a compatibility group other than ``S'' (e.g., B, C, or D) prior to 
the April 1, 2011 compliance date if intended for transportation by 
aircraft on or after that date. PHMSA also proposed that the effective 
date of testing to maintain Division 1.4S classification or 
reassignment to a higher compatibility group other than ``S'' be no 
later than January 1, 2014 for Division 1.4S articles approved prior to 
January 1, 2012 and are intended for domestic highway or rail 
transportation. For previously-approved affected articles transported 
by highway, rail and vessel, reassignment to a compatibility group 
other than ``S'' may be accomplished by using existing data and, when 
recommended by an authorized examination and testing agency, approved 
by PHMSA. For international highway, rail and vessel transportation, 
the effective date of Type 6(d) testing requirements or reassignment 
for new and previously produced affected articles would be January 1, 
2012 (i.e., the compliance date of a final rule under this docket, if 
adopted as proposed).
    A number of commenters (Baker, EBAD, ESD, IME, Infotrac, NNSA, OCS, 
SAAMI, and Titan) addressed our proposal to adopt the Type 6(d) test 
and associated requirements. Several commenters expressed support for 
comments submitted by IME and requested that PHMSA give consideration 
to their comments. Thus, our response to comments will primarily be 
structured based on the comments IME submitted.
    a. Compliance dates (i) Air transport. IME expressed concern that 
the proposed compliance date for Type 6(d) testing to determine 
Division 1.4S classification for materials to be transported by air 
precedes the compliance date for the rulemaking in general. IME stated:

    The ``compliance date of a final rule under this docket'' will 
be January 1, 2012. Simultaneously, however, the proposal 
establishes a compliance date for transportation by aircraft of 
April 1, 2011. Accordingly, the compliance date for an individual 
mode regulated under the rule would precede the compliance date for 
the rule itself, rendering the April 1, 2011 compliance date both 
unreasonable and unenforceable.

    We disagree. As general policy, PHMSA implements a one-year 
transition period for international harmonization rulemakings. Thus, we 
typically publish a rulemaking under the HM-215 docket to be effective 
January 1 of a given year (to coincide with international effective 
dates) and require compliance one year later to afford stakeholders the 
opportunity to prepare for compliance. PHMSA is not bound to the one 
year transition period and has discretion to institute an earlier 
compliance date when circumstances warrant. The implementation of this 
requirement was viewed to be significant by the ICAO Dangerous Goods 
Panel and an emergency addendum was requested from the Air Navigation 
Commission. Preventing the transportation of an explosive article with 
the ability to exit its packaging that could result in collateral 
damage on a passenger aircraft was determined to be an immediate safety 
concern and was implemented on very short notice for international air 
transportation. Therefore, because of concern for the safety in 
transport of these articles by air and to affect a transition for 
international air transport with minimal disharmony in compliance dates 
(the Type 6(d) test is required under ICAO Technical Instructions as of 
January 1, 2011), we proposed to implement the April 1, 2011, 
compliance date for Type 6(d) testing for transport by aircraft.
    IME also expressed concern that the proposed compliance date of 
April 1, 2011 for air transport is unattainable. IME stated further:

    [T]hat PHMSA's internal policy establishes a 120-day review 
period for processing approvals * * *. [W]e have determined that in 
order to meet the April 1, 2011 compliance deadline for air 
transportation, approval applicants planning to continue shipping by 
air would have to ensure that all required testing is completed and 
the results submitted to PHMSA by December 2, 2010. The required 
testing must be performed or witnessed by ``an authorized 
examination and testing agency approved by PHMSA.'' On average, the 
lead time required to schedule testing with a PHMSA-approved 
laboratory is six weeks. An additional two weeks would then be 
required for testing the laboratory to perform the required tests 
and generate a report * * *. Accordingly, applicants intending to 
meet the April 1, 2011 deadline would have [had to] finalize 
arrangements with the testing laboratories by October 4, 2010--
twenty-one days prior to the close of the public comment period * * 
*. Given the impossibility of timely compliance, the proposed April 
1, 2011 date will function not as a compliance deadline, but as an 
automatic prohibition on [of] air transport of the affected 1.4S 
articles.

    PHMSA acknowledges the strict compliance timeline proposed for the 
air transport of affected articles and substances. We note, however, 
that the PHMSA imposed 120-day period for

[[Page 3315]]

processing of approvals is not a minimum time period but general 
guidance for estimating the time period to review and process an 
approval application dependent on multiple factors such as the 
complexity of an application or errors in its submittal. The approval 
process may take less than 120 days and routinely does. Additionally, 
PHMSA's Approvals and Permits Division recently streamlined the 
explosive approval process to accommodate an influx of approval 
requests based on adoption of Type 6(d) test prescribed in this 
rulemaking. Finally, shippers are not constrained to the use of 
domestic laboratories approved by PHMSA but may utilize the resources 
of laboratories under the umbrella of other competent authorities 
(e.g., Transport Canada). However, given the strict timeline proposed 
in the August 2010 NPRM, the significant number of approval 
applications we expect to receive, and the potential for delays at 
authorized testing laboratories attempting to accommodate the volume of 
testing or reclassification requests, we are extending the compliance 
date for air transport to July 1, 2011.
    (ii) Vessel transport. IME noted our failure to indicate a 
compliance date for domestic vessel transportation. We agree. Our 
intent was to implement a compliance date that coincides with the 
effective date of the IMDG Code requirement for the Type 6(d) test 
(January 1, 2012). Therefore in this final rule, we will require the 
Type 6(d) test for Division 1.4S classification beginning January 1, 
2012 for both domestic and international vessel transportation.
    (iii) Modal variability. IME expressed concern that the varying 
compliance dates for air transport (proposed April 1, 2011), 
international highway, rail, and vessel (domestic and international) 
(proposed January 1, 2012), and domestic highway and rail (proposed 
January 1, 2014) will result in confusion and unintentional 
noncompliance with specific regard to downstream customers. IME 
reasoned:

    The customer has no way of knowing that the manufacturer ships 
only domestically [by highway] and has not, therefore, reclassified 
the product to meet the earlier compliance date for international 
transport. This leads to unintentional noncompliance by the 
downstream customer * * *. We recommend that PHMSA promulgate a 
single compliance date for all modes and for domestic and 
international transportation.

    We disagree. Unawareness of a requirement cannot be used as a 
defense for non-compliance. Downstream customers or shippers may 
utilize a number of resources to determine whether an explosive article 
or substance subject to the Type 6(d) test has been successfully 
tested. For example, they can obtain a copy of the approval issued by 
PHMSA. Additionally, it is the shipper's responsibility to properly 
class and describe a material (see Sec.  173.22) and to be trained on 
any applicable requirements (see Sec.  172.704) of the HMR. That said, 
the Approvals and Permits Division will issue guidance to all current 
approval holders for affected Division 1.4S articles and materials to 
provide detailed instruction on the new requirement for Type 6(d) 
testing. This will include issuing new or amended approvals indicating 
whether a Type 6(d) test has been successfully conducted which can then 
be used by downstream customers and shippers to aid in transport 
decision-making.
    b. Testing requirements. (i) Self-testing. In response to the 
ANPRM, IME recommended allowing self-testing and video documentation 
for articles previously approved as Division 1.4S. IME continued to 
assert that testing requirements for previously approved articles not 
be overly broad and questioned why this recommendation was not 
addressed even though PHMSA specifically acknowledged IME's comments in 
the NPRM. IME reiterated:

    Providing manufacturers with the option to self-test is an 
effective means of ensuring reasonable application of the new test. 
Additionally, allowing self-testing of already approved explosives 
articles will assist industry in minimizing the financial impact of 
implementation of a new test on already approved, safely 
transported, explosives.

    We disagree. PHMSA believes a uniform process for testing using the 
Type 6(d) test to determine Division 1.4S classification is the best 
approach and we do not believe incorporating variability into the 
process by allowing self-testing and video-documentation for already 
approved articles complements this approach. PHMSA understands the need 
to facilitate any possible cost reduction regarding the application of 
this new testing requirement. We also maintain, however, that in the 
interest of uniform safety standards under the HMR, requiring that 
testing be observed or conducted by a PHMSA-approved laboratory is the 
best approach. This approach will not be codified in the HMR but rather 
will be incorporated into the explosives approval process as specified 
in Sec.  173.56 of the HMR.
    (ii) Clarification of NPRM preamble. Certain phrases and terms were 
used in the August 2010, NPRM which have caused confusion. We would 
like to clarify. Regarding the phrase ``incremental testing,'' use of 
the phrase refers to the staggered compliance dates depending on the 
mode of transport or domestic/international transport and does not 
indicate differences in reclassification testing. We are removing any 
reference to this phrase in the preamble to this final rule to avoid 
further confusion. Regarding the term ``design,'' as in ``previously 
approved designs,'' the term was meant to signify individual explosives 
articles or substances. We are also deleting any use of this term in 
the preamble to this final rule to avoid any ambiguity in the use of 
the term.
    (iii) Modal difference. In response to our proposed implementation 
of the new testing requirement for Division 1.4S classification, IME 
objected to any varying testing criteria tied to the intended mode of 
transport, stating:

    Such action is not consistent with the UN classification system; 
additionally, an explosive's reaction to stimuli is not affected by 
the mode of transport. PHMSA offers no rationale for excluding the 
use of existing test data for the reclassification of articles 
intended for air transport, and the distinction would inevitably 
result in confusion and unintended noncompliance in the regulated 
community.

    We agree that there should be uniform testing criteria across all 
modes. We apologize for the lack of clarity in implementation of this 
new testing requirement and will clarify further in the following 
section (c) discussion of our implementation of the Type 6(d) test.
    (iv) Laboratory recommendation. For previously approved articles, 
we proposed to allow reassignment to a compatibility group other than 
``S'' using existing data and when recommended by a PHMSA-approved 
laboratory. IME did not support the proposal to require a 
recommendation from a PHMSA-approved laboratory where a previously 
approved article is being reassigned. IME argued:

    Inability to successfully pass the new Type 6(d) test does not 
invalidate the original laboratory tests and recommendation[s] that 
were previously sufficient to attain 1.4S classification. 
Accordingly, there is no rational basis for requiring a laboratory 
recommendation to support a downgrade in classification. A 
laboratory recommendation should only be required where the original 
classification is not supported by laboratory testing and a 
corresponding recommendation * * * [W]e are also concerned that if 
the proposal is promulgated as drafted, some testing laboratories 
may be reticent to issue the required recommendation solely on the 
basis of existing test data, and may require new testing.

    We appreciate the concerns presented by IME. Again, we apologize 
for any lack of clarity in implementing this new

[[Page 3316]]

provision. As indicated previously, our Approvals and Permits Division 
will be issuing guidance and instruction on testing or reclassification 
of previously approved Division 1.4S articles or substances. As part of 
that instruction and in order to alleviate any potential problems from 
laboratories being reticent to provide a recommendation based on 
existing data, the Approvals and Permits Division will be providing 
guidelines to laboratories for which types or batches of already 
approved articles and substances should be reclassed into which type of 
downgraded compatibility group.
    c. Implementation of the Type 6(d) test in the explosives approval 
process. As IME accurately summarized in its comments, there are three 
categories of explosive articles or substances affected by the test 
requirement: (1) Previously approved Division 1.4S articles that will 
pass the Type 6(d) test; (2) previously approved Division 1.4S articles 
that will not pass the Type 6(d) test and therefore need to be 
reassigned to a more conservative compatibility group other than ``S''; 
and (3) new explosive articles for which Division 1.4S classification 
must be determined through successful Type 6(d) testing. All explosive 
articles affected by the Type 6(d) test requirement fit into these 
three categories regardless of the mode of transport. The compliance 
date for affected articles is dependent upon the intended mode of 
transport and whether they are to be transported domestically or 
internationally. Beginning January 1, 2012, any new explosive articles 
must be successfully subjected to the Type 6(d) test to determine 
whether Division 1.4S classification is appropriate. However, for a new 
explosive material intended for transport by aircraft, the compliance 
date for successful Type 6(d) testing is no later than July 1, 2011. 
For existing approved Division 1.4S articles intended for transport by 
air, successful Type 6(d) testing is also required no later than July 
1, 2011; otherwise, the articles must be reassigned to another 
compatibility group and a new approval issued by PHMSA prior to being 
offered for transportation or transported by aircraft. Beginning 
January 1, 2012, existing approved Division 1.4S articles intended for 
international transport by highway, rail, or vessel and for domestic 
transport by vessel, successful Type 6(d) testing is required; 
otherwise, the articles must be reassigned to another compatibility 
group and a new approval issued by PHMSA prior to being offered for 
transportation. Finally, for existing approved Division 1.4S articles 
intended for domestic transportation by highway or rail, successful 
testing or compatibility group reassignment is required beginning 
January 1, 2014.
    We realize the intended mode of transport may change as markets 
change and evolve but staggered compliance dates we believe are 
necessary in order to provide sufficient time to manufacturers, 
shippers, PHMSA-approved laboratories, and our Approvals and Permits 
Division to accommodate the number of approved Division 1.4S articles 
that will need testing or reclassification as well as attempting to 
allay some of the costs to manufacturers who only transport by domestic 
highway or rail.
    d. Federal considerations. Two commenters (ESB, NNSA) within the 
Department of Defense and Department of Energy, respectively, objected 
to the Type 6(d) test requirement for previously approved Division 1.4S 
explosive material based on cost and logistical concerns. NNSA noted:

    [M]ore significant than the added costs, are the limited testing 
assets available necessary to complete testing by the prescribed 
deadline in the NPRM. [We do not] recognize the need to conduct UN 
Test Series 6(d) testing on all future permanent hazard 
classification requests as specified in the NPRM.

    ESB added:

    [We object to] with applying the test Type 6(d) for articles 
previously classified. DOD has been assigning classifications using 
a methodology that includes assessing projections, fireballs, and 
jets of flame from unconfined initiation testing. DOD would consider 
this methodology as equivalent testing and criteria for the 
assignments of the eight Divisions 1.4 explosive [a]rticles. The DOD 
[has] not noted any transportation issues with the 378 articles 
assigned these UN numbers * * * Conducting test Type 6(d) for the 
378 articles would take a considerable amount of time without any 
credible or measurable increase in safety * * * Reclassifying * * * 
by reassigning CGs other than S is also not a viable option due to 
the complexity of DOD logistics. Consolidating, and remarking each 
shipping container located at strategic positions around the world 
for [defense purposes] would be costly, time consuming and 
potentially have little safety improvements.

    ESB recommended adding a grandfathered exception or issuing a 
special permit for previously approved DOD Division 1.4S material. We 
acknowledge concerns by Federal agencies regarding costs and time 
constraints in the interest of national security. We are currently 
working directly with potentially affected government stakeholders to 
remedy concerns regarding implementation of the new requirement for the 
Type 6(d) test on such entities.
7. Classification of Sour Crude Oil
    PHMSA agreed with comments submitted in response to the October 
2009 ANPRM that a new proper shipping name is not necessary and that 
there are more appropriate ways to communicate the potential inhalation 
hazard risk to transport workers. Therefore, in the August 2010 NPRM, 
PHMSA proposed to adopt the new proper shipping name found in the UN 
Model Regulations--``Petroleum sour crude oil, flammable, toxic''--with 
the letter ``I'' in Column (1) of the HMT indicating that this 
description is appropriate for use during international transportation. 
However, PHMSA did not propose to require use of the new proper 
shipping name for domestic transportation. PHMSA did propose that a new 
marking be applied to bulk packagings containing sour crude oil to 
communicate the potential inhalation risk in transportation.
    Three commenters (API, ATA, DGAC) opposed our proposed requirements 
as ill-conceived and impractical and had concerns with the new marking. 
They believe the new marking is not necessary based on industry best 
practices already in place. One commenter (AAR) sought clarification of 
rail carrier requirements in relation to the proposed marking 
requirement. Although the commenters opposed our proposed requirements, 
they strongly support hazard communication processes and procedures to 
protect employees, the public and the environment from any unreasonable 
risk of danger from hydrogen sulfide gas. API noted:

    Cargo specific testing of individual packages upon loading, 
followed by the required identification, classification, packaging 
selection, marks, labels, placards, and documentation process is 
impractical. The physical and chemical criteria of the DG/HazMat 
define the basic shipping information * * * The preparation of 
shipping information and selection of packagings is typically done 
well in advance of loading on the basis of known, reliably measured, 
physical and chemical criteria of the materials being transported. 
When a wide range of the test results is possible, the DG/HazMat 
classifiers generally utilize the most conservative data to develop 
the basic shipping information * * * It is impossible to predict the 
concentration of H2S in the head space vapors evolving from liquid 
petroleum crude oils. There is not [a] standardized test, 
statistical correlation, or known methodology to do this * * * 
Without a reliable, proven methodology, any attempt to develop a 
classification process regarding potential, future H2S vapor space 
concentrations is unrealistic * * * API could

[[Page 3317]]

support the use of a differentiated graphic, unique in communicating 
the potential H2S vapor [but any] such mark should be considered 
voluntary and not mandated * * *. Companies should be allowed the 
flexibility in choosing an option that works best for their 
operations.

    DGAC added:

    [W]e are concerned that providing a warning for select crude 
oils may result in decreased vigilance when other substances also 
posing a potential hydrogen sulfide risk are handled * * *. If * * * 
PHMSA maintains that a mark is still necessary, we recommend that 
the applicability of any marking be limited to cargo tank truck 
operations * * * PHMSA should allow the warning to appear in the 
vicinity of the loading/unloading operation or on the vehicle at the 
loading location. This would avoid the need to add and remove the 
mark from the cargo tank truck * * * We consider the proposed GHS 
poison mark to be inappropriate * * * Applying the PHMSA proposed 
mark on crude oil tanks that do not meet the inhalation toxicity 
criteria results in a hazard communication conflict which should and 
can be avoided * * *. Should PHMSA maintain a warning is needed, we 
recommend a warning sign in English that conveys the message that 
there is a potential hydrogen sulfide hazard. An example could be * 
* * ``Danger, Possible Hydrogen Sulfide Inhalation Hazard,'' * * * 
[to be possibly] supplemented by pictograms.

    ATA expressed concerns that:

    Not every load of sour crude will form hydrogen sulfide during 
transportation, which will require carriers to repeatedly affix and 
remove markings * * * If carriers are required to repeatedly alter 
marking requirements, issues of employee safety from climbing on top 
of tank trucks as well as economic issues * * * must be better 
understood. [We] recommend that the warning be located at the 
loading or unloading facility rather than on the tank truck or other 
bulk container.

    We agree in part with the comments. We continue to maintain that 
there is a safety risk to hazmat employees that may become exposed to 
hydrogen sulfide vapor in proximity to openings on packagings during a 
loading or unloading operation due to elevated concentrations of 
hydrogen sulfide vapors. We do not believe this risk is limited to 
cargo tank motor vehicles. It may be that the primary mode of 
transportation for petroleum crude oil is by cargo tank motor vehicle, 
but we also continue to maintain that any proposed requirement should 
apply to all bulk packagings as we believe this risk may be present in 
any packaging with a bulk quantity of petroleum crude oil.
    PHMSA agrees with commenters who have stated that a hazard warning 
statement specific to hydrogen sulfide gas on bulk packagings would 
provide for appropriate communication of the risk of potential exposure 
to such gas. PHMSA notes that such a marking is both specific to the 
gas and aligns with corresponding warnings currently employed in 
practice on the shipping documentation. Therefore, in this final rule, 
PHMSA is amending the marking requirement originally proposed to 
provide more flexibility to shippers and carriers by allowing a text 
warning such as ``Danger, Possible Hydrogen Sulfide Inhalation Hazard'' 
on bulk packagings containing sour crude to communicate the potential 
inhalation risk in transportation. See Section 172.327 for a discussion 
of the new marking requirements.
8. IBC Rebottling
    In the NPRM, PHMSA proposed to adopt the revised definition of 
``repair'' for composite IBCs consistent with international standards. 
To specifically address commenters' concerns, PHMSA noted that any 
proposed compliance date would be no earlier than January 1, 2012, thus 
providing ample time to comply with the new IBC requirement. We did not 
receive any additional comments in response to the NPRM. Therefore, in 
this final rule we are adopting the revised definition of ``repair'' of 
an IBC as proposed. See Section 180.350 for a discussion of the revised 
requirement.
9. Metal Hydride Storage Systems in Conveyances
    In the August 2010 NPRM, PHMSA proposed to adopt the standards for 
the construction, qualification, marking and requalification of 
hydrogen in metal hydride storage systems adopted in the UN Model 
Regulations. We did not receive any additional comments in response to 
the NPRM. Therefore, in this final rule we are adopting the 
requirements as proposed. See Section 173.311 for a discussion of 
requirements for hydrogen in a metal hydride storage system.
10. In Vitro Testing for Corrosivity
    Based on the overwhelming support for adoption into the HMR, in the 
NPRM PHMSA proposed to adopt and authorize the use of the OECD in vitro 
methods. We received over 2,200 comments additional to that received 
from PETA, in response to the NPRM supporting the adoption of in vitro 
testing methods to determine corrosivity and urging PHMSA to stop the 
requirement for use of methods based on live animal testing. Therefore, 
in this final rule we are adopting the OECD in vitro testing methods as 
proposed. See Section 173.137 for further discussion of such methods.

B. Harmonization Amendments Not Considered for Adoption in This Final 
Rule

    This final rule makes changes to the HMR based on amendments made 
in the UN Model Regulations (sixteenth revised edition), IMDG Code 
(Amendment 35-10) and the ICAO Technical Instructions (2011-2012), 
which becomes effective January 1, 2011 (the IMDG Code is effective 
January 1, 2012). We are not, however, adopting all the amendments made 
to the various international standards into the HMR. In many cases, we 
have not adopted amendments to the international recommendations and 
regulations because the framework or structure of the HMR makes 
adoption unnecessary. In other cases, we have handled, or will be 
handling, the amendments in separate rulemaking proceedings.
    One of the goals of this rulemaking is to continue to maintain 
consistency between the HMR and the international requirements. We are 
not striving to make the HMR identical to the international 
regulations, but rather to remove or avoid potential barriers to 
international transportation.
    Below is a listing of those significant amendments to the 
international regulations that we are not adopting in this final rule, 
with a brief explanation of why the amendment was not included:
1. Requirements for Radioactive Materials
    In the NPRM, we did not propose to adopt provisions pertaining to 
the transportation of Class 7 (radioactive) materials into the HMR. 
Amendments to requirements pertaining to the transportation of Class 7 
(radioactive) materials are based on changes contained in the 
International Atomic Energy Agency (IAEA) publication, ``IAEA Safety 
Standards: Regulations for the Safe Transport of Radioactive 
Materials.'' Due to their complexity, these changes are being addressed 
in a separate rulemaking.
2. Requirements for Lithium Batteries
    PHMSA published an NPRM under Docket HM-224F (75 FR 1302, January 
11, 2010) that proposed to adopt provisions to ensure all lithium 
batteries are packaged properly to reduce the possibility of damage to 
lithium batteries that could lead to a catastrophic incident, and to 
minimize the consequences of an incident should one occur. In addition, 
PHMSA proposed to require lithium battery shipments to be accompanied 
by hazard communication that ensures appropriate

[[Page 3318]]

and careful handling by air carrier personnel, including the flight 
crew, and informs both transport workers and emergency response 
personnel of actions to be taken in an emergency. The NPRM, which PHMSA 
developed in close coordination with our colleagues in the Federal 
Aviation Administration, is the latest in a series of actions PHMSA has 
taken to address the very serious risks posed by lithium batteries in 
transportation. The NPRM included proposed revisions to the HMR that 
were based on lithium battery provisions in the sixteenth revised 
edition of the UN Model Regulations. Therefore, except for wheelchairs 
powered by lithium ion batteries, we are not adopting new provisions 
pertaining to the transportation of lithium cells and batteries in this 
rulemaking. The docket for the lithium battery rulemaking can be found 
elsewhere at http://www.regulations.gov under PHMSA-2009-0095.
    We note that a number of commenters objected to our inclusion of 
limitations on the stowage of lithium batteries in Sec.  175.75 of the 
HMR and strongly urged that the limitations be removed from this 
rulemaking and addressed in a separate lithium battery rulemaking such 
as HM-224F. We agree. All reference to lithium batteries in our 
revisions to Sec.  175.75 are removed from this rulemaking.
3. Requirements for Air Packaging
    We are not adopting provisions pertaining to certain packagings 
offered for transportation by aircraft under this rulemaking. PHMSA is 
considering certain amendments to the HMR related to requirements for 
the packaging of hazardous materials intended for transportation by 
aircraft under a separate docket (HM-231A). These would include 
amendments based on the reformatted packing instructions in the 2011-
2012 ICAO Technical Instructions. PHMSA published an ANPRM (73 FR 
38361, July 7, 2008) and an NPRM (75 FR 27273, May 14, 2010) related to 
combination packaging standards offered in air transportation. See 
http://www.regulations.gov under PHMSA-2007-29364 for more information.

IV. Section-by-Section Review

    Following is a section-by-section review of the amendments in this 
final rule:

Part 171

Section 171.7
    The ``National Technology Transfer and Advancement Act of 1996'' 
directs agencies to use voluntary consensus standards. According to the 
Office of Management and Budget (OMB) Circular A-119, ``Federal 
Participation in the Development and Use of Voluntary Consensus 
Standards and in Conformity Assessment Activities,'' government 
agencies must use voluntary consensus standards wherever practical in 
the development of regulations. Agency adoption of industry standards 
promotes productivity and efficiency in government and industry, 
expands opportunities for international trade, conserves resources, 
improves health and safety, and protects the environment.
    To these ends, PHMSA actively participates in the development and 
updating of consensus standards through representation on more than 20 
consensus standard bodies. PHMSA regularly reviews updated consensus 
standards and considers their merit for inclusion in the HMR.
    Section 171.7 lists all materials incorporated by reference (IBR 
materials) into the HMR. For this rulemaking, we evaluated updated 
international consensus standards and regulations pertaining to proper 
shipping names, hazard classes, packing groups, special provisions, 
packaging authorizations, air transport quantity limitations, and 
vessel stowage requirements and determined that the revised standards 
provide an enhanced level of safety without imposing significant 
compliance burdens. These materials have a well-established and 
documented safety history. Their adoption maintains the high safety 
standard currently achieved under the HMR.
    Some commenters (IATA, PRBA, Saft) indicated concern that the fifth 
revised edition of the UN Recommendations on the Transportation of 
Dangerous Goods, Manual of Tests and Criteria (UN Manual) was not 
included among the IBR materials to be updated and suggest that PHMSA 
include the document.
    We agree. PHMSA proposed to incorporate by reference the fifth 
revised edition of the UN Manual under docket HM-224F published January 
11, 2010 (75 FR 1302) because the revised version of the manual 
contained updated tests for lithium cells and batteries. However, that 
rulemaking will have an effective date later than this final rule. This 
rule contains provisions regarding new test requirements for other 
materials (e.g., explosives) that are found in the updated edition of 
the UN Manual making it necessary for us to incorporate by reference 
the fifth edition. Therefore, we are including the updated fifth 
revised edition of the UN Manual and updating the IBR materials 
referenced in the HMR by adding and revising material under the 
following organizations:

Section 171.8
    This section defines terms generally used throughout the HMR that 
have broad or multi-modal applicability. We received no comments 
regarding our proposed adoption of new definitions. Therefore, in this 
final rule PHMSA is adding the following defined terms based on their 
adoption in the UN Model Regulations:
    Metal hydride storage system. This term means a single complete 
hydrogen storage system that includes a receptacle, metal hydride, 
pressure relief device, shut-off valve, service equipment and internal 
components used for the transportation of hydrogen only.
    Open cryogenic receptacle. This term means a transportable 
thermally insulated receptacle for refrigerated liquefied gases 
maintained at atmospheric pressure by continuous venting of the 
refrigerated gas.
    Additionally, we proposed to revise the definition of Oxidizing gas 
to specify that an oxidizing gas is a pure gas or gas mixture with an 
oxidizing power greater than 23.5% as determined by a method specified 
in ISO 10156:1996 or 10156-2:2005. See also Sections 172.101 and 
173.115, for discussion of changes to the ``Compressed gas, n.o.s., 
UN1956.'' HMT entry and definition, respectively. We received no 
comments on the revised definition. Therefore, in this final rule we 
are adopting the revision as proposed.
Section 171.23
    Section 171.23 prescribes the conditional requirements for specific 
materials and packages transported under the various international 
standards as permitted by the HMR. In this final rule we are removing 
the Sec.  171.23(b)(9) requirement that stipulates Division 6.1 
poisonous materials transported as limited quantities are not excepted 
from labeling. This change aligns the labeling requirements in the HMR 
for limited quantities with the international standards without 
compromising safety.
Section 171.25
    Section 171.25 prescribes the additional requirements for specific 
materials and packages transported under the IMDG Code as permitted by 
the HMR. In this final rule, we are deleting paragraphs (c)(5) and 
(d)(3). Paragraphs (c)(5) and (d)(3) required portable tanks, cargo 
tanks, and tank cars containing cryogenic liquids transported by vessel 
to be stowed on deck regardless of the stowage requirements authorized 
under the IMDG Code. The IMDG Code now requires this same stowage for 
certain packagings containing cryogenic materials aboard a vessel, 
thus, paragraphs (c)(5) and (d)(3) are no longer necessary.
    Effective January 1, 1997, vehicles and mechanical equipment 
containing internal combustion engines were no longer subject to the 
IMDG Code as conditionally designated under Amendment 28-96. Effective 
January 1, 2012, such articles will once again be subject to the IMDG 
Code under Amendment 35-10. Because the new requirements in the IMDG 
Code are more stringent than requirements for similar material in the 
HMR, PHMSA is amending Sec.  171.25 by revising paragraph (b)(1) and 
adding a new paragraph (b)(4) permitting use of the IMDG Code or the 
HMR to prepare and stow vehicles and mechanical equipment containing 
internal combustion engines when offered for transport by vessel.

Part 172

Section 172.101
    Introductory text to the Sec.  172.101 HMT contains explanatory 
text for each of the columns that comprise the HMT. Currently, Sec.  
172.101(c)(10) provides specific requirements regarding the selection 
of an appropriate proper shipping name for mixtures and solutions 
containing more than one hazardous material of the same hazard class. 
In many cases, such mixtures and solutions are best described by a 
generic or ``not otherwise specified'' entry (i.e., an ``n.o.s.'' 
entry). For example, a solution containing two or more flammable liquid 
constituents may best be described under the entry ``Flammable liquids, 
n.o.s., UN1993.'' However, in some cases where two or more hazardous 
materials are present, a single hazardous material may predominate 
where the other hazardous materials may be present in only trace 
amounts. In such cases, a description applicable to the predominant 
material may be more appropriate. A recent incident underscores the 
importance of using the most specific and appropriate shipping 
description. In that incident, an aluminum cylinder containing 99.9% 
pure ethyl chloride ruptured in storage incidental to transport. It was 
determined that the root cause was a reaction between the cylinder's 
contents and the aluminum. The relevant construction standard for the 
cylinder indicated that ethyl chloride was reactive with aluminum and 
that aluminum was not recommended for the transport of ethyl chloride. 
However, the shipper selected a generic compressed gas shipping 
description rather than the ethyl chloride name due to the presence of 
trace amounts of other hazardous materials. While we note that the 
general requirements for packagings still broadly address the 
responsibility of the shipper in selecting a packaging that is 
compatible with its lading, and that these requirements were also 
applicable and apparently overlooked, the incident nonetheless 
highlights the benefit of using a more specific description, where 
appropriate, to help ensure that the most appropriate transport 
provisions are followed.
    To address this issue, the UN Model Regulations were amended to 
require, except as otherwise specified, that a mixture or solution of a 
single predominant hazardous material containing only traces of one or 
more additional hazardous materials listed by name in the HMT or 
additional non-hazardous constituents be assigned the UN number and 
proper shipping name of the predominant material contributing to the 
overall hazard classification of the mixture or solution. Adopting a 
similar provision in the HMR will enhance a shipper's ability to select 
the most appropriate shipping description. In the NPRM, PHMSA proposed 
to add a new paragraph, Sec.  172.101(c)(10)(iv), outlining the 
authorization to describe the mixture or solution based on the 
predominant material contributing to the hazard classification.
    One commenter (DOE) suggested that we remove the reference to non-
hazardous material in Sec.  172.101(c)(10)(iv) because the mixture of 
hazardous material and non-hazardous material is already addressed in 
Sec.  172.101(c)(10)(i). Additionally, the commenter asked for 
clarification of instances when the provision should be used and asked 
to define the meaning of ``trace amounts.''
    We agree. It is correct that Sec.  172.101(c)(10)(i) already 
addresses a mixture or solution of a hazardous material and non-
hazardous material. The provision pertains to a mixture or solution 
containing non-hazardous material in such quantities that it does not 
alter the physical state or purity of the hazardous material it is 
mixed with, as well as either the hazard classification, packing group, 
subsidiary hazard, or emergency response procedures. The intent of new 
paragraph Sec.  172.101(c)(10)(iv) is to provide instruction for 
selecting the most appropriate proper shipping name for a mixture or 
solution of a hazardous material and traces of one or more other 
hazardous materials, one or more non-hazardous materials, or both. 
Where such a mixture or solution occurs that the trace amount of 
material does not affect the classification, the material must be 
described using the most appropriate proper shipping name for the 
predominant hazardous material. Based on the comment received and 
reconsideration of our proposal, we are instead revising paragraph 
(c)(10)(i) to provide clarification on properly describing a material 
that is a mixture or solution of a predominant hazardous material and 
trace amounts of hazardous or non-hazardous material, or both; rather 
than add a new paragraph (c)(10)(iv). The six conditions in Sec.  
172.101(c)(10)(i) that currently limit a mixture or solution of 
hazardous material with a non-hazardous material from being described 
using the proper shipping name of the hazardous material would also 
apply to a mixture or solution of a single predominant hazardous 
material and trace amounts of other hazardous or non-hazardous 
materials or both.
    With regard to instances when the provision would be used, we would 
expect it to be applied in cases of mixtures or solutions of a 
hazardous material that contain small amounts of preservatives or are 
contaminated with trace amounts of hazardous material in such a way 
that the ``trace amounts'' do not affect the packaging, the hazard 
class, the packing group, etc of the hazardous material. As for 
defining ``trace amounts'' we do not specifically define this term 
because determination of when an amount of material affects the hazard 
classification is highly variable depending on the physical and 
chemical properties of the materials involved and the quantities of 
material involved. Therefore, in this final rule, we are revising Sec.  
172.101(c)(10)(i) to provide instruction on properly describing a 
material that is a mixture or solution of a predominant hazardous 
material and trace amounts of hazardous or non-hazardous material, or 
both.
    Paragraph (e) of Sec.  172.101 provides explanations for the 
letters that precede identification numbers assigned to proper shipping 
names in the HMT. In this final rule, PHMSA is adding an explanation 
for identification numbers associated with certain descriptions under 
the ICAO Technical Instructions and are preceded by the letters ``ID.'' 
Additionally, PHMSA is authorizing use of the international air 
description, ``ID8000, Consumer commodity, 9'' in the HMT with material 
and article eligibility for use of the description based on Special 
provision A112 and Packing Instruction Y963 of the 2011-2012 ICAO 
Technical Instructions.

Hazardous Materials Table (HMT)

    In this final rule, PHMSA is making various amendments to the HMT. 
Readers should review all changes for a complete understanding of the 
amendments. For purposes of the Government Printing Office's 
typesetting procedures, changes to the HMT appear under three sections 
of the Table, ``remove,'' ``add,'' and ``revise.'' Certain entries in 
the HMT, such as those with revisions to the proper shipping names, 
appear as a ``remove'' and ``add.'' Amendments to the HMT include the 
following:

New HMT entries

[[Page 3321]]

----------------------------------------------------------------------------------------------------------------
 
----------------------------------------------------------------------------------------------------------------
UN3482..............................................  Alkali metal dispersions, flammable or Alkaline earth
                                                       metal dispersions, flammable.
UN3496..............................................  Batteries, nickel-metal hydride.
----------------------------------------------------------------------------------------------------------------

    This new HMT entry for UN3496 includes a W in Column (1) to 
indicate use of this hazardous materials description is limited to 
vessel transport of these materials.
    Two commenters (Saft, PRBA) indicated concern with our proposed 
assignment of Special Provision 130 (for transportation of dry 
batteries--i.e., ``Batteries, dry, sealed, n.o.s.'') to this entry and 
the potential for confusion leading to use of this entry for modes 
other than vessel.
    We agree. To help clarify the use of this entry, we have included 
additional language in Column (2) to refer shippers transporting 
nickel-metal hydride batteries by modes other than vessel to the HMT 
entry ``Batteries, dry, sealed, n.o.s.'' for instruction on the 
transport requirements for nickel-metal hydride batteries. 
Additionally, we have revised Special Provision 130 to make clear that 
for other than nickel-metal hydride batteries transported by vessel 
subject to Special Provision 340, dry batteries must be transported in 
accordance with Special Provision 130.

----------------------------------------------------------------------------------------------------------------
 
----------------------------------------------------------------------------------------------------------------
UN3485..............................................  Calcium hypochlorite, dry, corrosive or Calcium
                                                       hypochlorite mixtures, dry, corrosive with more than 39%
                                                       available chlorine (8.8% available oxygen).
UN3487..............................................  Calcium hypochlorite, hydrated, corrosive or Calcium
                                                       hypochlorite, hydrated mixture, corrosive with not less
                                                       than 5.5% but not more than 16% water.
UN3486..............................................  Calcium hypochlorite mixture, dry, corrosive with more
                                                       than 10% but not more than 39% available chlorine.
ID8000..............................................  Consumer commodity.
----------------------------------------------------------------------------------------------------------------

    This shipping description is added to the HMT as a Class 9 
miscellaneous hazardous material to be used for the air transportation 
of limited quantities of certain hazardous materials of Class 2 (non-
toxic aerosols only), Class 3 (PG II and III only), Division 6.1 (PG 
III only), and of UN identification numbers UN3077, UN3082, and UN3175, 
provided such materials do not have a subsidiary risk and are 
authorized aboard a passenger-carrying aircraft. This amendment is 
based on changes incorporated into the 2011-2012 ICAO TI.

----------------------------------------------------------------------------------------------------------------
 
----------------------------------------------------------------------------------------------------------------
UN3484..............................................  Hydrazine aqueous solution, flammable with more than 37%
                                                       hydrazine, by mass.
UN3495..............................................  Iodine.
----------------------------------------------------------------------------------------------------------------

    Iodine is transported globally under a number of different shipping 
descriptions dependent on the shipper. In the interest of reducing 
risks associated with transport of iodine under various descriptions 
and therefore, various packaging, we are adding this unique UN 
identification number and shipping description to provide for specific 
packaging requirements and faster identification and access to 
emergency response information.

----------------------------------------------------------------------------------------------------------------
 
----------------------------------------------------------------------------------------------------------------
UN1471..............................................  Lithium hypochlorite, dry or Lithium hypochlorite mixture,
                                                       Division 5.1, PG III.
----------------------------------------------------------------------------------------------------------------

    Lithium hypochlorite is a common commercial product used as a 
disinfectant that is often mixed with other non-hazardous organic 
salts. Currently, the HMT only provides for a Division 5.1, PG II 
designation for this material, yet testing conducted in accordance with 
the UN Manual of Tests and Criteria has indicated that some common 
commercial mixtures meet the criteria for classification in Division 
5.1, PG III. Therefore, PHMSA is adding a line to the current entry to 
allow for classification of lithium hypochlorite and mixtures of 
lithium hypochlorite in PG III, where appropriate.
    One commenter (FMC) noted that the addition of the proposed PG III 
entry for the ``Lithium hypochlorite, UN1471'' shipping description 
retains the italicized text ``with more than 39% available chlorine 
(8.8% available oxygen)'' as well as the word ``dry'' for lithium 
hypochlorite mixtures and that this is not consistent with the 
hazardous materials description in the dangerous goods list in the UN 
Model Regulations, the ICAO Technical Instructions, and the soon to be 
adopted IMDG Code. FMC requested that PHMSA revise the entry by 
deleting the qualifying text as well as the word ``dry'' to be 
consistent with international standards and regulations and to provide 
shippers with the most appropriate shipping description for the 
transport of lithium hypochlorite materials. Additionally, FMC stated:

    [M]ore fundamental and practical problems will arise if this 
qualifying text is retained in the HMR entry for UN1471. Some of the 
commercial lithium hypochlorite products shipped domestically and 
internationally by FMC have less than 39% available chlorine (8.8% 
available oxygen), and so would not be properly described by the 
entry as it is proposed to be modified. [T]hese products 
nevertheless meet the criteria for classification in Division 5.1, 
Packing Group II or III. Consequently, under the HMR, FMC must 
describe these products by an appropriate entry in the HMT 
associated with the correct class and packing group, namely 
``Hypochlorites, inorganic, n.o.s.'' (UN3212) if the product meets 
Packing Group II criteria, or, since UN3212 does not provide a 
Packing Group III option, ``Oxidizing solid, n.o.s.'' (UN1479) if 
the product meets the criteria for assignment to Packing Group III. 
Thus, for road and rail transport within the United States FMC's 
lithium hypochlorite products would have to be described by one of 
three different entries.

    We agree. Removing the italicized text would facilitate a uniform 
process of describing lithium hypochlorite materials for transport 
purposes without reducing the safety of transport when using this 
description in lieu the descriptions discussed in the comment by FMC. 
Additionally, we are making a conforming amendment (with the IMDG Code) 
to the PG II entry for UN1471 to assign special provisions T3 and TP33 
applicable to a portable tank when used to transport this material. T3 
outlines

[[Page 3322]]

the minimum test pressure, minimum shell thickness, bottom opening 
requirements, and pressure relief requirements in addition to the 
design and constructions requirements for the portable tank. TP33 
outlines provisions for transport of granular or powdered solids. 
Therefore, in this final rule, we are adopting the PG III entry for 
``Lithium hypochlorite, UN1471'' without the italicized text and the 
word ``dry,'' as well as making a conforming revision to the shipping 
description for the PG II entry already in the HMT to read, ``Lithium 
hypochlorite, dry or Lithium hypochlorite mixtures, UN1471.''

UN3483..............................................  Motor fuel anti-knock mixture, flammable.
UN3494..............................................  Petroleum sour crude oil, flammable, toxic (this entry is
                                                       identified in the HMT as appropriate for international
                                                       transportation under Sec.   172.101(b)(5)).
UN3492..............................................  Toxic-by-inhalation liquid, corrosive, flammable, n.o.s.

                                                       equal to 500 LC 50.
UN3493..............................................  Toxic-by-inhalation liquid, corrosive, flammable, n.o.s.
                                                       with an inhalation toxicity lower than or equal to 1000

                                                       equal to 500 LC 50.
UN3489..............................................  Toxic-by-inhalation liquid, flammable, corrosive, n.o.s.
                                                       with an inhalation toxicity lower than or equal to 1000
                                                       ml/m \3\ and saturated vapor concentration greater than
                                                       or equal to 10 LC 50.
UN3490..............................................  Toxic-by-inhalation liquid, water-reactive, flammable,
                                                       n.o.s. with an inhalation toxicity lower than or equal to
                                                       200 ml/m \3\ and saturated vapor concentration greater
                                                       than or equal to 500 LC 50.
UN3491..............................................  Toxic-by-inhalation liquid, water-reactive, flammable,
                                                       n.o.s. with an inhalation toxicity lower than or equal to
                                                       1000 ml/m \3\ and saturated vapor concentration greater
                                                       than or equal to 10 LC 50.
----------------------------------------------------------------------------------------------------------------

    Based on a recommendation by a commenter (PPG), we note that two 
new entries for toxic-by-inhalation (TIH) material (i.e., UN3492 and 
UN3493) added in the sixteenth revised edition of the UN Model 
Regulations and in this final rule will likely be removed from the 
dangerous goods table in the seventeenth revised edition of the UN 
Model Regulations. Shippers who choose to use these new descriptions on 
shipping papers and markings on boxes may incur additional costs when 
having to change the material descriptions again should the 
descriptions be removed from the UN Model Regulations and subsequently, 
the HMR.
    Additionally, because of the addition of generic TIH descriptions 
for toxic, flammable, corrosive material (i.e., UN 3488, UN3499), PPG 
believes the domestic entries for ``sec-Butyl chloroformate, NA2742'' 
and ``Isobutyl chloroformate, NA2742'' are obsolete and recommended 
that these materials be described using the generic TIH descriptions 
for consistent hazard communication of these materials between modes of 
transportation.
    We agree. Therefore, in this final rule, as a conforming amendment 
to the addition of the generic TIH entries, we are deleting the 
domestic use entries ``sec-Butyl chloroformate, NA2742'' and ``Isobutyl 
chloroformate, NA2742'' from the HMT.

Amendments to the Column (1) Symbols

    The entries ``Elevated temperature liquid, flammable, n.o.s., with 
flash point above 37.8 [deg]C, at or above its flash point, UN3256,'' 
``Elevated temperature liquid, n.o.s., at or above 100 [deg]C and below 
its flash point (including molten metals, molten salts, etc.), 
UN3257,'' and ``Elevated temperature solid, n.o.s., at or above 240 
[deg]C, UN3258'' are revised by adding the symbol G. The symbol G 
identifies proper shipping names for which a technical name of the 
hazardous material is required in parentheses in association with the 
basic description. Requiring the technical name(s) for certain elevated 
temperatures materials will help emergency responders in selecting the 
proper materials for extinguishing a fire involving these hazardous 
materials and will aid in estimating the temperature properties of the 
materials (e.g., the melting point).
    The entries ``Metal catalyst, dry, UN2881'' and ``Metal catalyst, 
wetted with a visible excess of liquid, UN1378'' are revised by adding 
the symbol G. The symbol G identifies proper shipping names for which a 
technical name of the hazardous material is required in parentheses in 
association with the basic description. Requiring the technical name(s) 
for metal catalysts will aid emergency responders in selecting the 
proper fire suppressant (e.g., CO2) if the hazardous 
material is involved in a fire or in identifying other materials the 
metal catalyst could react with.
    The entry ``Powder, smokeless, UN0509,'' is revised by deleting the 
symbol D. The symbol D identifies a proper shipping name for domestic 
use only. This entry has been adopted into the UN Model Regulations, 
the ICAO TI, and the IMDG Code. This deletion is consistent with our 
final rule published under Docket HM-215J (74 FR 2200, January 14, 
2009) in which we indicated our intent to remove the symbol D in a 
future rulemaking upon adoption of the entry into international 
regulations.
    For the following Division 5.1 (oxidizer) materials and Division 
6.1 (toxic) materials, the entries are revised by adding the symbol G. 
The symbol G identifies proper shipping names for which one or more 
technical names of the hazardous material must be entered in 
parentheses in association with the basic description on a shipping 
paper. Knowledge of the technical name of toxic materials may aid 
emergency responders with implementing more appropriate first aid 
measures:

Amendments to the Column (2) Hazardous Materials Descriptions and 
Proper Shipping Names

    The proper shipping name for the entry ``Detonator, assemblies, 
non-electric, for blasting, UN0500,'' is revised by removing the comma 
after ``Detonator'' to read ``Detonator assemblies, non-electric, for 
blasting.'' This revision appears as a ``Remove/Add'' in this 
rulemaking.
    The proper shipping name for the entry ``Engines, internal 
combustion, flammable gas powered, UN3166,'' is revised to read 
``Engines, internal combustion or Engines, fuel cell, flammable gas 
powered.'' This revision appears as a ``Remove/Add'' in this 
rulemaking.
    One commenter (IATA) suggests that we revise this proper shipping 
name to the singular ``engine'' in alignment with use of the singular 
form for the entries in the UN Model Regulations. We disagree. As 
indicated by the commenter, Sec.  172.101(c)(1) authorizes use of 
proper shipping names in the singular or plural form. Therefore, we 
believe it is not necessary to revise the proper shipping name to the 
singular ``engine'' when the shipper is authorized to modify the proper 
shipping name between singular and plural forms.
    The proper shipping name for the entry ``Engines, internal 
combustion, flammable liquid powered, UN3166,'' is revised to read 
``Engines, internal combustion or Engines, fuel cell, flammable liquid 
powered.'' This revision appears as a ``Remove/Add'' in this 
rulemaking.
    One commenter (IATA) suggests that we revise this proper shipping 
name to the singular ``engine'' in alignment with use of the singular 
form for the entries in the UN Model Regulations. We disagree. As 
indicated by the commenter, Sec.  172.101(c)(1) authorizes use of 
proper shipping names in the singular or plural form. Therefore, we 
believe it is not necessary to revise the proper shipping name to the 
singular ``engine.''
    The proper shipping names ``Formaldehyde, solutions, flammable, 
UN1198'' and ``Formaldehyde, solutions, with not less than 25 percent 
formaldehyde, UN2209'' are revised to remove an errant comma between 
the words ``Formaldehyde'' and ``solutions.'' This revision appears as 
a ``Remove/Add'' in this rulemaking.
    The proper shipping name for the entry ``1-Hydroxybenzotriazole, 
anhydrous, wetted with not less than 20 percent water, by mass, 
UN3474'' is revised to read ``1-Hydroxybenzotriazole, monohydrate.'' 
This revision appears as a ``Remove/Add'' in this rulemaking.
    The proper shipping name for the PG II entry for Lithium 
hypochlorite, dry with more than 39% available chlorine (8.8% available 
oxygen) or Lithium hypochlorite mixture, dry with more than 39% 
available chlorine (8.8% available oxygen), UN1471'' is revised to read 
``Lithium hypochlorite, dry or Lithium hypochlorite mixture'' to 
conform with the addition of the new PG III entry and international use 
of this proper shipping name. This revision appears as a ``Remove/Add'' 
in this rulemaking.
    The proper shipping name for the entry ``Nitric acid other than red 
fuming, with less than 65 percent nitric acid, UN2031'' is revised to 
read ``Nitric acid other than red fuming, with more than 20 percent and 
less than 65 percent nitric acid, UN2031.'' The proper shipping name 
for the Packing Group I entry ``Nitric acid other than red fuming, with 
more than 70 percent nitric acid, UN2031'' is added to the HMT. In a 
final rule published on January 14, 2009 (HM-215J; 74 FR 2200), errors 
were made to both nitric acid entries and in this final rule, PHMSA 
aligns them correctly in accordance with the various international 
standards. Additionally, we are removing the outdated Packing Group II 
entry ``Nitric acid other than red fuming, with not more than 70 
percent nitric acid, UN2031'' that should have been removed from the 
HMT in the same final rule.
    The proper shipping name for the entry ``Tars, liquid including 
road asphalt and oils, bitumen and cut backs, UN1999'' is revised to 
read ``Tars, liquid including road oils and cutback bitumens.'' The 
entries in the HMT applicable to transport of bitumen may cause 
confusion with respect to the proper classification of the material. 
The entries include ``Combustible liquid, n.o.s., NA1993, combustible 
liquid'' and ``Tars, liquid including road asphalt and oils, bitumen 
and cut backs, UN1999, 3,'' and the entries ``Elevated temperature 
liquid, flammable, n.o.s., UN3256, 3'' and ``Elevated temperature 
liquid, n.o.s., UN3257, 9,'' when the material is heated and offered 
for transport. Bitumen is a hydrocarbon material derived from crude oil 
having a flashpoint of 160 [deg]C or greater. Bitumens typically do not 
meet the classification for a Class 3 flammable

[[Page 3324]]

liquid except for cutback bitumens which are blended with a flammable 
material such as kerosene. Also, road asphalt is bitumen mixed with 
sand and fillers which also does not meet the classification for a 
Class 3 flammable liquid. Therefore, we are revising the proper 
shipping name ``Tars, liquid including road asphalt and oils, bitumen 
and cut backs'' by removing reference to asphalt and clarifying 
applicability to cutback bitumens to read ``Tars, liquid including road 
oils and cutback bitumens.'' This revision appears as a ``Remove/Add'' 
in this rulemaking.
    The proper shipping name for the entry ``Trinitro-meta-cresol, 
UN0216'' is revised to read ``Trinitro-m-cresol.'' This revision 
appears as a ``Remove/Add'' in this rulemaking.
    The proper shipping name for the entry ``Vehicle, flammable gas 
powered, UN3166,'' is revised to read ``Vehicle, flammable gas powered 
or Vehicle, fuel cell, flammable gas powered.'' This revision appears 
as a ``Remove/Add'' in this rulemaking.
    The proper shipping name for the entry ``Vehicle, flammable liquid 
powered, UN3166,'' is revised to read ``Vehicle, flammable liquid 
powered or Vehicle, fuel cell, flammable liquid powered.'' This 
revision appears as a ``Remove/Add'' in this rulemaking.

Amendments to the Column (3) Hazard Class or Division

    PHMSA is revising the classification of a number of entries to 
Division 6.1 poisonous primary hazards for consistency with the 
adoption of classification changes into the sixteenth revised edition 
of the UN Model Regulations. The changes are based on data provided 
from a thorough review of literature on toxic-by-inhalation materials. 
The review of literature is provided in Informal Document UN/SCETDG/33/
INF.8 submitted to the 33rd session of the UN Sub-Committee of Experts 
on the Transport of Dangerous Goods which is available at http://www.unece.org/trans/main/dgdb/dgsubc/c3inf33.html.
    For the entry ``Tetranitromethane, UN1510,'' the Class 5 (oxidizer) 
material's primary hazard is revised to a Division 6.1 (poisonous) 
material primary hazard.
    For the following Class 3 (flammable liquid) materials, the Class 3 
primary hazard is revised to a Division 6.1 (poisonous) material 
primary hazard.

----------------------------------------------------------------------------------------------------------------
 
----------------------------------------------------------------------------------------------------------------
UN2481..............................................  Ethyl isocyanate.
UN2486..............................................  Isobutyl isocyanate.
UN2483..............................................  Isopropyl isocyanate.
UN3079..............................................  Methacrylonitrile, stabilized.
UN2605..............................................  Methoxymethyl isocyanate.
----------------------------------------------------------------------------------------------------------------

    For the following Class 8 (corrosive) materials, the Class 8 
primary hazard is revised to a Division 6.1 (poisonous) material 
primary hazard.

----------------------------------------------------------------------------------------------------------------
 
----------------------------------------------------------------------------------------------------------------
UN1810..............................................  Phosphorous oxychloride.
UN1834..............................................  Sulfur chloride.
UN1838..............................................  Titanium tetrachloride.
----------------------------------------------------------------------------------------------------------------

Amendments to the Column (5) Packing Group (PG)

    The entry ``Carbon dioxide, solid or Dry ice, UN1845'' is revised 
by deleting the PG III designation. In general, the PG assigned to a 
material identifies the degree of hazard the material represents and 
determines the performance level of the packaging required for the 
material. For example, a PG II material (i.e., a moderate hazard 
material) is considered more hazardous and requires more stringent 
packaging than a PG III material (i.e., a low hazard material). Dry ice 
presents minimal risk during transport except where concentrations may 
build up in a confined space. Therefore, in this final rule, PHMSA is 
deleting the PG III designation from the entry.
    For the following Division 6.1 poisonous materials, the PG is 
revised to read PG I.

----------------------------------------------------------------------------------------------------------------
 
----------------------------------------------------------------------------------------------------------------
UN2668..............................................  Chloroacetonitrile.
UN1810..............................................  Phosphorous oxychloride.
UN2474..............................................  Thiophosgene.
UN1838..............................................  Titanium tetrachloride.
----------------------------------------------------------------------------------------------------------------

    PHMSA is making this revision to the PG assignment for these 
entries for consistency with the adoption of changes into the sixteenth 
revised edition of the UN Model Regulations. The changes are based on 
data provided from a thorough review of literature on toxic-by-
inhalation materials. The review of literature is provided in Informal 
Document UN/SCETDG/33/INF.8 submitted to the 33rd session of the UN 
Sub-Committee of Experts on the Transport of Dangerous Goods which is 
available at http://www.unece.org/trans/main/dgdb/dgsubc/c3inf33.html.

Amendments to the Column (6) Label(s)

    For the following hazardous material entries, PHMSA is revising the 
label requirements for consistency with changes made to the 
classification of these materials under amendments to Column (3) (see 
above). The Class 3 (flammable liquid), Class 8 (corrosive), or 
Division 5.1 (oxidizer) primary hazard labels, as appropriate, and the 
Division 6.1 (poisonous) subsidiary hazard label are revised to a 
Division 6.1 (poisonous) material primary hazard label and Class 3, 
Class 8, or Division 5.1 subsidiary hazard label to read ``6.1, 3,'' 
``6.1, 8,'' or ``6.1, 5.1,'' as appropriate.

----------------------------------------------------------------------------------------------------------------
 
----------------------------------------------------------------------------------------------------------------
UN2481..............................................  Ethyl isocyanate.
UN2486..............................................  Isobutyl isocyanate.
UN2483..............................................  Isopropyl isocyanate.
UN3079..............................................  Methacrylonitrile, stabilized.

[[Page 3325]]

 
UN2605..............................................  Methoxymethyl isocyanate.
UN1810..............................................  Phosphorous oxychloride.
UN1834..............................................  Sulfur chloride.
UN1838..............................................  Titanium tetrachloride.
----------------------------------------------------------------------------------------------------------------

    The entry ``Chlorosilanes, toxic, corrosive, flammable, n.o.s., 
UN3362'' is revised by correctly ordering the sequence of labeling 
hazards to reflect the proper shipping name to read ``6.1, 8, 3.''

Amendments to the Column (7) Special Provisions

    The entry ``Chloropicrin, UN1580'' is revised by replacing the 
portable tank instruction T Code T14 with T22. The UN Committee of 
Experts on the Transport of Dangerous Goods revised the T Code 
assignment for a number of Division 6.1 (toxic-by-inhalation) materials 
from T14 to T22. Assigning T22 requires a higher pressure for the 
periodic hydrostatic test (6 bar to 10 bar) and a thicker minimum shell 
thickness (6 mm to 10 mm). Therefore, for consistency with revisions 
made to the T Code assignments under the sixteenth revised edition of 
the UN Model Regulations, we are revising the T Code to read T22.
    The entry ``Compressed gas, n.o.s., UN1956'' is revised by deleting 
special provision 77 which authorizes the use of this entry for 
mixtures of gases with less than 23.5% oxygen when no other oxidizing 
gases are present. Because we are modifying the definition of oxidizing 
gas in Sec.  171.8 of the HMR to indicate that ``a gas which may, by 
providing oxygen, cause or contribute to the combustion of other 
material more than air does means pure gases or gas mixtures with an 
oxidizing power greater than 23.5% oxygen'' and because the entry 
``Compressed gas, oxidizing, n.o.s., UN3156'' is currently available in 
the HMT, the special provision is redundant and no longer necessary.
    The entry ``Environmentally hazardous substance, solid, UN3077'' is 
revised by adding new special provision A112 authorizing the 
transportation of certain IBCs containing this material up to a maximum 
net quantity of 1,000 kg by passenger or cargo-only aircraft.
    The entry ``Ethylene oxide or Ethylene oxide with nitrogen up to a 
total pressure of 1 MPa (10 bar) at 50 degrees C, UN1040 is revised by 
deleting special provision A59 and adding new special provision 342. 
The provisions in A59 applied only to air transport but they now apply 
to all modes under new Special provision 342. See Section 172.102 
special provisions for a discussion of new special provision 342.
    The entry ``1-Hydroxybenzotriazole, monohydrate, UN3474'' is 
revised by deleting special provision 162. Special provision 162 
requires that for the material to be transported as a Division 4.1 
desensitized material, it must be transported in such a manner that at 
no time during the course of transportation does the percentage 
concentration of water fall below 20%. Anhydrous hydroxybenzotriazole 
rapidly converts to the monohydrate form in the presence of water, that 
is, the thermally stable form of the substance. Additionally, tests 
have indicated that the monohydrate maintains its water content under 
temperature conditions encountered in storage and transport over 
extended periods of time. This conforms to the intent of the provisions 
specified in special provision 162 and therefore, we are deleting 
special provision 162 from the entry.
    The entry ``Motor fuel anti-knock mixtures, UN1649'' is revised by 
deleting special provision 151. Special provision 151 requires that if 
this material also meets the definition of a Class 3 (flammable) liquid 
under Sec.  173.120 of the HMR, a FLAMMABLE LIQUID label is required 
and the basic description on the shipping paper must indicate the Class 
3 subsidiary hazard. However, because of the addition of the new entry 
``Motor fuel anti-knock mixtures, flammable, UN3483'' which indicates a 
Class 3 subsidiary hazard, we believe it is no longer necessary to 
assign special provision 151 to this entry.
    The entry ``Nitrogen, refrigerated liquid cryogenic liquid, 
UN1977'' is revised by adding new special provisions 345 and 346. See 
Section 172.102 special provisions for a discussion of new special 
provisions 345 and 346.
    The entry ``Oxygen, compressed, UN1072'' is revised by adding 
special provision 110 authorizing an actuating cartridge (e.g., power 
device cartridges of Division 1.4, compatibility groups C and S) to be 
installed on a cylinder containing oxygen without changing the 
classification of Division 2.2. See Section 172.102 special provisions 
for a discussion of our revision to special provision 110.
    The entry ``Pentaerythrite tetranitrate or Pentaerythritol 
tetranitrate or PETN, with not less than 7 percent wax by mass, 0411)'' 
is revised by assigning special provision 120 to the entry. A final 
rule published in the Federal Register under Docket HM-215B (62 FR 
24689, May 6, 1997), added special provision 120 to Sec.  172.102(c)(1) 
of the HMR and assigned it to one of the phlegmatized HMT entries for 
PETN (UN0411). In this final rule, PHMSA is reassigning special 
provision 120 to UN0411 in Column (7) of the HMT because it never 
appeared in the subsequent printing of the HMR but the requirement 
remains valid.
    The entry ``Petroleum crude oil, UN1267'' is revised by adding new 
special provision 357 instructing a shipper, if applicable, to use the 
entry ``Petroleum sour crude oil, flammable, toxic, UN3494'' for 
petroleum crude oil containing hydrogen sulfide in sufficient 
concentration that vapors evolved from the crude oil can present an 
inhalation hazard when this material is offered for transportation 
internationally. See Section 172.102 Special provisions for a 
discussion of special provision 357.
    The entry ``Zinc ammonium nitrate, UN1512'' is revised by deleting 
special provision IP2 which requires IBCs other than metal or rigid 
plastic IBCs to be offered for transportation in a closed freight 
container or a closed transport vehicle.
    The following Division 1.4, Compatibility Group S (1.4S) explosive 
article entries in the HMT are revised by adding new special provision 
347 which limits the use of the entries to only those articles that 
have successfully passed Test series 6(d) of Part I of the UN Manual of 
Tests and Criteria. For clarity, we are also adding the special 
provision to the entry ``Cartridges, power device (used to project 
fastening devices), ORM-D'' to indicate that the requirements for 
special provision 347 also apply to Division 1.4S articles that may be 
reclassed as ORM-D. See Section 172.102 Special Provisions for a 
discussion of new special provision 347.

----------------------------------------------------------------------------------------------------------------
 
----------------------------------------------------------------------------------------------------------------
UN0323..............................................  Cartridges, power device.
UN0460..............................................  Charges, bursting, plastics bonded.
UN0445..............................................  Charges, explosive, commercial without detonator.

[[Page 3326]]

 
UN0441..............................................  Charges, shaped without detonator.
UN0500..............................................  Detonator assemblies, non-electric for blasting.
UN0456..............................................  Detonators, electric for blasting.
UN0366..............................................  Detonators for ammunition.
UN0455..............................................  Detonators, non-electric for blasting.
----------------------------------------------------------------------------------------------------------------

    The following Division 6.1 (toxic-by-inhalation) materials entries 
are revised by replacing the portable tank instruction T Code T22 with 
T20. The UN Committee of Experts on the Transport of Dangerous Goods 
revised the T Code assignment for a number of Division 6.1 (toxic-by-
inhalation) materials from T14 to T20. Assigning T20 requires a higher 
pressure for the periodic hydrostatic test (6 bar to 10 bar) and a 
thicker minimum shell thickness (6 mm to 8 mm). This change is 
consistent with the T Code assigned to the same materials in the HMT. 
However, for the materials listed below, we assigned a T Code T22 which 
requires a minimum shell thickness of 10 mm. We do not believe there 
would be a safety risk in reducing the minimum shell thickness for 
portable tanks containing these materials from 10 mm to 8 mm. 
Therefore, for consistency with revisions made to the T Code 
assignments under the sixteenth revised edition of the UN Model 
Regulations as well as consistency with the current assignment of T20 
to a number of other Division 6.1 (toxic-by-inhalation material) 
entries, the T Code T20 would be assigned for the following materials.

----------------------------------------------------------------------------------------------------------------
 
----------------------------------------------------------------------------------------------------------------
UN2484..............................................  tert-Butyl isocyanate.
UN2481..............................................  Ethyl isocyanate.
UN2486..............................................  Isobutyl isocyanate.
UN2483..............................................  Isopropyl isocyanate.
UN2605..............................................  Methoxymethyl isocyanate.
UN2482..............................................  n-Propyl isocyanate.
----------------------------------------------------------------------------------------------------------------

    The following Division 6.1 (toxic-by-inhalation) material entries 
are revised by adding the portable tank special provision TP13 as a 
conforming amendment to the changes to the PG assignment for these 
materials (see Amendments to Column (5) above). Special provision TP13 
requires the use of self-contained breathing apparatus when the 
hazardous material is transported by vessel.

----------------------------------------------------------------------------------------------------------------
 
----------------------------------------------------------------------------------------------------------------
UN2668..............................................  Chloroacetonitrile.
UN1810..............................................   Phosphorous oxychloride.
UN1834..............................................  Sulfur chloride.
UN2474..............................................  Thiophosgene.
----------------------------------------------------------------------------------------------------------------

    The following organometallic substance entries are revised by 
adding portable tank special provision TP36 which authorizes use of 
fusible elements in the vapor space on portable tanks transporting 
these materials. See Section 178.275 for a discussion of the authorized 
use of fusible elements on portable tanks.

----------------------------------------------------------------------------------------------------------------
 
----------------------------------------------------------------------------------------------------------------
UN3392..............................................  Organometallic substance, liquid, pyrophoric.
UN3394..............................................   Organometallic substance, liquid, pyrophoric, water-
                                                       reactive.
UN3398..............................................   Organometallic substance, liquid, water-reactive.
UN3399..............................................  Organometallic substance, liquid, water-reactive,
                                                       flammable.
UN3391..............................................  Organometallic substance, solid, pyrophoric.
UN3393..............................................  Organometallic substance, solid, pyrophoric, water-
                                                       reactive.
UN3400..............................................  Organometallic substance, solid, self-heating.
UN3395..............................................  Organometallic substance, solid, water-reactive.
UN3396..............................................  Organometallic substance, solid, water-reactive,
                                                       flammable.
UN3397..............................................  Organometallic substance, solid, water-reactive, self-
                                                       heating.
----------------------------------------------------------------------------------------------------------------

    The following Division 5.1 (oxidizer) substance entries are revised 
by adding new special provision W1. Special provision W1 excepts these 
substances from the HMR for vessel transport when transported in non-
friable prill or granule form provided the substance has been 
successfully tested in accordance with the UN Manual of Tests and 
Criteria.

----------------------------------------------------------------------------------------------------------------
 
----------------------------------------------------------------------------------------------------------------
UN1486...................................................  Potassium nitrate.
UN1498...................................................  Sodium nitrate.
UN1499...................................................  Sodium nitrate and potassium nitrate mixtures.
----------------------------------------------------------------------------------------------------------------

Amendments to the Column (8) Packaging Authorizations

    The four flammable liquid entries ``Alcohols, n.o.s., UN1987,'' 
``Ethanol, UN1170,'' ``Formaldehyde solutions, flammable, UN1198'' and 
``Isopropanol, UN1219'' are revised in Column (8A) by adding reference 
to Sec.  173.4b for additional exceptions for these materials. Section 
173.4b prescribes the requirements for de minimis quantities of 
hazardous materials offered for transportation and transported by all 
modes, domestic or international. We

[[Page 3327]]

are adding a new paragraph (b) to except non-infectious specimens 
(e.g., museum specimens) preserved with small amounts of certain Class 
3 materials from the HMR as recently adopted in the international 
standards. This amendment is consistent with previous interpretations 
we have issued on this matter.
    The entry ``Hydrogen in a metal hydride storage system or Hydrogen 
in a metal hydride storage system contained in equipment or Hydrogen in 
a metal hydride storage system packed with equipment, UN3468'' is 
revised in Column (8B) by deleting the reference to Sec.  173.214 for 
authorized non-bulk packaging and adding new section reference Sec.  
173.311. See Section 173.311 for a discussion of authorized packaging 
provisions for hydrogen in a metal hydride storage system.
    The entry ``Polyester resin kit, UN3269'' is revised by amending 
Columns (8A) and (8B) to read 165 in reference to packaging provisions 
in Sec.  173.165. Column (8A) previously referred to Sec.  173.152 and 
Column (8B) referred to Sec.  173.225 for authorized packaging. For 
clarity and consistency, such articles are now subject to packaging 
provisions incorporated into the HMR specific to these articles.

Amendments to the Column (9) Quantity Limitations

    We received three comments (3M, IATA, UPS) requesting that PHMSA 
harmonize with ICAO Technical Instructions amendments that forbid the 
transport of certain chlorosilane materials in passenger aircraft 
(UN1818, UN2434, UN2437, UN2986, and UN2987).
    We agree. Our original intent was to incorporate these amendments 
in the August 2010 proposed rule. Therefore, based on our intent and 
comments received, the following entries are revised by amending the 
Column (9A) package quantity limitations for passenger air and rail to 
read ``Forbidden,'' consistent with the 2011-2012 ICAO Technical 
Instructions:

----------------------------------------------------------------------------------------------------------------
 
----------------------------------------------------------------------------------------------------------------
UN1818..............................................  Silicon tetrachloride.
UN2434..............................................  Diphenyldichlorosilane.
UN2437..............................................  Methylphenyldichlorosilane.
UN2986..............................................  Chlorosilanes, corrosive, flammable, n.o.s.
UN2987..............................................  Chlorosilanes, corrosive, n.o.s.
----------------------------------------------------------------------------------------------------------------

    The entries ``Medicine, liquid, flammable, toxic, n.o.s., UN3248,'' 
``Medicine, liquid, toxic, n.o.s., UN1851,'' and ``Medicine, solid, 
toxic, n.o.s., UN3249'' are revised in the Column (9A) and (9B) package 
quantity limitations authorizing a greater maximum quantity per package 
consistent an changes made to the 2011-2012 ICAO TI.

Amendments to the Column (10) Vessel Stowage Requirements

    Vessel stowage location (10A). For the following materials, we are 
revising the authorized stowage locations in Column (10A) by revising 
the stowage category to read D. Assignment of stowage category D means 
the material must be stowed ``on deck only'' on a cargo vessel and on a 
passenger vessel carrying a number of passengers limited to not more 
than the larger of 25 passengers or one passenger per each 3 meters of 
overall vessel length. The material is prohibited on passenger vessels 
in which the limiting number is exceeded.

----------------------------------------------------------------------------------------------------------------
 
----------------------------------------------------------------------------------------------------------------
UN1951..............................................  Argon, refrigerated liquid (cryogenic liquid).
UN2187..............................................  Carbon dioxide, refrigerated liquid.
UN1143..............................................  Crotonaldehyde or Crotonaldehyde, stabilized.
UN1963..............................................  Helium, refrigerated liquid (cryogenic liquid).
UN1970..............................................  Krypton, refrigerated liquid (cryogenic liquid).
UN1647..............................................  Methyl bromide and ethylene dibromide mixtures, liquid.
UN2644..............................................  Methyl iodide.
UN2477..............................................  Methyl isothiocyanate.
UN2606..............................................  Methyl orthosilicate.

UN2474..............................................  Thiophosgene.
UN1838..............................................  Titanium tetrachloride.
UN2591..............................................  Xenon, refrigerated liquid (cryogenic liquids).
----------------------------------------------------------------------------------------------------------------

    Vessel stowage codes (10B). For the following hazardous materials, 
we are removing from Column (10B) stowage code 18 (stowage code 143 for 
UN3392), which prohibits the material from being transported on any 
vessel carrying explosives (except Division 1.4S explosives), and we 
are adding in its place stowage code 78, which requires the materials 
to be stowed ``separated longitudinally by an intervening complete 
compartment or hold from'' explosives.

----------------------------------------------------------------------------------------------------------------
 
----------------------------------------------------------------------------------------------------------------
UN1131..............................................  Carbon disulfide.
UN1259..............................................  Nickel carbonyl.
UN3392..............................................  Organometallic substance, liquid, pyrophoric.
UN3394..............................................  Organometallic substance, liquid, pyrophoric, water-
                                                       reactive.

Section 172.102 Special Provisions
    Section 172.102 lists special provisions applicable to the 
transportation of specific hazardous materials. Special provisions 
contain packaging requirements, prohibitions, and exceptions applicable 
to particular quantities or forms of hazardous materials. PHMSA is 
adopting the following revisions to Sec.  172.102, special provisions.
    Special provision 15 is revised by removing redundant regulatory 
text applicable to ``Chemical kits, UN3316'' and ``First aid kits, 
UN3316.''
    Special provision 40 is revised to indicate that ``Polyester resin 
kit, UN3269'' requires specification outer packaging based on the PG 
assigned to the base (Class 3) material unless excepted as a limited or 
excepted quantity material. This revision is a clarification of the 
existing requirement.
    Special provision 77 is deleted. Special provision 77 allows use of 
the entry ``Compressed gas, n.o.s., UN1956'' for mixtures of gases with 
less than 23.5% oxygen when no other oxidizing gases are present. PHMSA 
is modifying the definition of oxidizing gas in Sec.  171.8 to state 
that ``a gas which may, by providing oxygen, cause or contribute to the 
combustion of other material more than air does,'' meaning, pure gases 
or gas mixtures with an oxidizing power greater than 23.5% oxygen. 
Because of the availability of the entry ``Compressed gas, oxidizing, 
n.o.s., UN3156'' in the HMT, we believe special provision 77 is no 
longer necessary.
    Special provision 78 is revised to direct shippers to use the entry 
``Compressed gas, oxidizing, n.o.s., UN3156'' to describe compressed 
air that contains pure gases or gas mixtures with an oxidizing power 
greater than 23.5% oxygen. PHMSA is modifying the definition of 
oxidizing gas in Sec.  171.8 of the HMR to indicate that ``a gas which 
may, by providing oxygen, cause or contribute to the combustion of 
other material more than air does,'' meaning, pure gases or gas 
mixtures with an oxidizing power greater than 23.5% oxygen. Therefore, 
we are revising this special provision to emphasize the revised 
definition and use of the proper shipping description.
    Special provision 110 is revised to include oxygen cylinders for 
emergency use. Fire extinguishers (UN1044) are assigned special 
provision 110, which authorizes the installation of a cartridge power 
device (of Divisions 1.4C and S) on the fire extinguisher without 
changing its classification from Division 2.2, provided the actuating 
cartridge does not contain deflagrating (propellant) explosives 
exceeding 3.2 g. Many of these types of fire extinguishers are used in 
commercial aircraft applications where the actuating cartridge is 
necessary for remote activation to discharge the fire suppressant 
contained in the cylinder. Similarly, commercial aircraft are being 
designed to incorporate small oxygen cylinders in the overhead panels 
above passenger seats to provide emergency oxygen in the event of a 
depressurization. The design of the system is that a small actuating 
cartridge attached to each cylinder will be initiated once the 
passenger starts breathing into the mask, which will allow the flow of 
oxygen from these cylinders. In connection with the manufacturing and 
maintenance of the aircraft, it is necessary for these small cylinders 
to be transported with the actuator installed. The principal hazard 
presented by these oxygen cylinders remains that of Division 2.2, and 
not the Division 1.4 explosive hazard of the actuating cartridge. 
Therefore, in this final rule PHMSA is authorizing the transport of 
oxygen cylinders for emergency use with an installed actuating 
cartridge without changing the classification of Division 2.2 provided 
that the total quantity of deflagrating (propellant) explosives does 
not exceed 3.2 g per oxygen cylinder, and further provided that the 
cylinders have an effective means of preventing inadvertent activation.
    Special provision 130 is revised in conformance with adoption of 
new special provision 340 and new Sec.  172.101 HMT entry, ``Batteries, 
nickel-metal hydride, UN3496,'' applicable to nickel-metal hydride 
batteries transported by vessel. Two commenters (PRBA, Saft) requested 
a revision to clarify the appropriate use of this special provision for 
the transport of nickel-metal hydride batteries. We agree that special 
provision 130 should be clarified to avoid confusion over appropriate 
use of entries applying to nickel-metal hydride batteries. Because 
these batteries are dry batteries, they are subject to conditions in 
special provision 130, which outlines that the provision applies to dry 
batteries when not specifically covered by another entry in the HMT. 
Because there is now another entry for nickel-metal hydride batteries 
that is modal specific, there is potential for confusion. We are 
therefore adding language to special provision 130 clarifying that, 
except for nickel-hydride batteries shipped under conditions specified 
in special provision 340 for vessel transportation, nickel-metal 
hydride batteries are covered by the entry ``Batteries, dry, sealed, 
n.o.s.''
    In addition, one commenter (PRBA) suggested that we codify guidance 
offered in several recently issued letters of interpretation (e.g., 
Ref. No. 09-0194) indicating our determination that spent or used dry 
batteries of not more than 9 volts are not likely to generate a 
dangerous quantity of heat, short circuit, or create sparks during the 
normal course of transportation and thus, are not subject to the HMR 
when transported for purposes of recycling, reconditioning, or 
disposal. We agree. Therefore, in this final rule we are revising 
special provision 130 by adding a conditional exception for the ground 
transportation of spent or used dry batteries.
    For conformance with the addition of new proper shipping names for 
UN3166, special provision 134 is revised to specify that a battery-
powered vehicle or equipment that also contains an internal combustion 
engine must be consigned under the entry ``Engine, internal combustion, 
flammable gas powered'' or ``Engine, internal combustion, flammable 
liquid powered'' or ``Vehicle, flammable gas powered'' or ``Vehicle, 
flammable liquid powered,'' as appropriate. These entries include 
hybrid electric vehicles powered by both an internal combustion engine 
and batteries. Furthermore, a battery-powered vehicle or equipment that 
contains a fuel cell-powered engine must be consigned under the entry 
``Engine, fuel cell, flammable gas powered'' or ``Engine, fuel cell, 
flammable liquid powered'' or ``Vehicle, fuel cell, flammable gas 
powered'' or ``Vehicle, fuel cell, flammable liquid powered,'' as 
appropriate. These entries include hybrid electric vehicles powered by 
a fuel cell, an internal combustion engine, and batteries.
    Special provision 135 is revised to specify that an internal 
combustion engine installed in a vehicle must be consigned to the entry 
``Vehicle, flammable gas powered'' or ``Vehicle, flammable liquid 
powered,'' as appropriate. These entries include hybrid electric 
vehicles powered by both an internal combustion engine and installed 
wet, sodium or lithium batteries. If a fuel cell-powered engine is 
installed in a vehicle, the vehicle must be consigned using the entry 
``Vehicle, fuel cell, flammable gas powered'' or ``Vehicle, fuel cell, 
flammable liquid powered,'' as appropriate. These entries include 
hybrid electric vehicles powered by a fuel cell, an internal combustion 
engine, and batteries.
    Special provision 149 is revised to indicate the exception provided 
may not

[[Page 3329]]

be used for transportation by aircraft. This special provision 
authorizes an increased amount of certain Class 3 (flammable liquid) 
materials in PG II that are also consumer commodities. We received one 
comment, from Safety Specialists, Inc. (SSI), opposing the elimination 
of air eligibility for use of the exception provided in the special 
provision. SSI asserts that because the materials currently authorized 
to use the packaging exception provided by special provision 149 are 
not ``extremely'' hazardous materials, they should continue to be 
authorized in air transportation in far greater quantities per inner 
packaging than are limited quantities packaged under the ICAO Technical 
Instructions. We disagree. Standardization in today's safety culture 
enhances safety, lowers training costs and facilitates commerce through 
greater productivity. PHMSA has made concessions in this final rule, 
such as lifting the Sec.  175.75 cargo compartment loading restriction 
on packages of limited quantity materials, to offset per inner and 
outer packaging limitations adopted through harmonization with the ICAO 
Technical Instructions. We will also vigorously advocate for change at 
the international level when warranted.
    Special provision 157 is deleted because the language of this 
provision has been combined with the language of revised special 
provision 135. Special provision 157 was assigned to the entries 
``Vehicle, flammable gas powered'' and ``Vehicle, flammable liquid 
powered'' and instructed shippers that these entries include hybrid 
electric vehicles powered by both internal combustion engines and 
installed wet, sodium or lithium batteries. This language is now in 
special provision 135.
    Special provision 167 is revised to require a metal hydride storage 
system installed in conveyances, to be approved by the Associate 
Administrator before acceptance for transport. Special provision 167 is 
also applicable, where appropriate, to UN3166 entries powered by fuel 
cells.
    Special provision 198 is revised to include ``Perfumery products, 
UN1266'' among the list of products that nitrocellulose solutions 
containing not more than 20% nitrocellulose can be transported as. 
PHMSA is also revising this provision to clarify that the 
nitrocellulose may not contain more that 12.6% nitrogen by dry mass.
    A new special provision 340 is added to provide special instruction 
for the vessel transport of nickel-metal hydride batteries (including 
cells). Except for nickel-metal hydride button cells or nickel-metal 
hydride cells or batteries packed with or contained in equipment, when 
nickel-metal hydride batteries are loaded in a vessel cargo transport 
unit in a total quantity of 100 kg gross mass or more, shipment of the 
nickel-metal hydride batteries is subject to the shipping paper, 
dangerous cargo manifest requirements under Sec.  176.30, and stowage 
conditions assigned to the ``Batteries, nickel-metal hydride, UN3496'' 
entry in the Sec.  172.101 HMT. Additionally, the nickel-metal hydride 
batteries are required to be securely packed and protected against a 
dangerous evolution of heat, short circuits and damage to terminals.
    A new special provision 342 is added to be consistent with the 
adoption of the same provisions in the UN Model Regulations and the 
IMDG Code as well as amendments made to special provision A131 in the 
ICAO Technical Instructions. The special provision allows sterilization 
devices containing ethylene oxide conforming to the conditions in the 
special provision and packaged in accordance with Sec.  173.4a of the 
HMR to be offered for transportation and transported by all modes even 
though Column (9A) of the Sec.  172.101 HMT lists the material as 
forbidden by passenger aircraft. The addition of this special provision 
coincides with the deletion of special provision A59 which restricted 
the applicability of the special provision to air transport. See 
Special provision A59 for additional discussion of this amendment.
    A new special provision 343 is added and assigned to the new HMT 
entry ``Petroleum sour crude oil, flammable, toxic, UN3494,'' 
indicating that for international transportation, this entry in the HMT 
must be used for petroleum crude oil containing hydrogen sulfide in 
sufficient concentration that vapors evolved from the crude oil can 
present an inhalation hazard. However, any bulk packaging used for the 
domestic transport of petroleum crude oil would be required to be 
marked in accordance with the new markings prescribed in Sec.  172.327 
of the HMR to provide warning of the potential hazard from inhalation 
of hydrogen sulfide vapors.
    A new special provision 345 is added excepting from the 
requirements of the HMR ``Nitrogen, refrigerated liquid cryogenic 
liquid, UN1977'' transported in open cryogenic receptacles with a 
maximum capacity of 1 L. The receptacles must be constructed with glass 
double walls having the space between the walls vacuum insulated and 
each receptacle must be transported in an outer packaging with 
sufficient cushioning and absorbent materials to protect the receptacle 
from damage.
    A new special provision 346 is added excepting from the 
requirements of the HMR ``Nitrogen, refrigerated liquid cryogenic 
liquid, UN1977'' transported in accordance with the requirements for 
open cryogenic receptacles in Sec.  173.320 of the HMR. The receptacle 
must contain no hazardous materials other than the liquid nitrogen 
which must be fully absorbed in a porous material in the receptacle.
    A new special provision 347 is added restricting the use of certain 
HMT entries classed as Division 1.4S explosive materials to those 
articles successfully passing Test series 6(d) of Part I of the UN 
Manual of Tests and Criteria. See Section 172.101 Hazardous Materials 
Table (HMT) for the list of proper shipping names that are assigned 
special provision 347. A Division 1.4 explosive is defined as an 
explosive that presents a minor explosion hazard such that hazardous 
effects are confined to a package and no projection of fragments of 
appreciable size or range are expected; and that an external fire must 
not cause virtually instantaneous explosion of almost the entire 
contents of a package containing a Division 1.4 explosive. Under Sec.  
173.58 of the HMR, an explosive article or substance is subjected to 
Test Series 6(a), 6(b), and 6(c) for assignment to an appropriate 
division (e.g. Division 1.4). Explosive articles or substances are 
assigned to Division 1.4, Compatibility Group S (1.4S) if hazardous 
effects are confined within a package or the blast and projection 
effects do not significantly hinder emergency response efforts. Test 
Series 6(a), 6(b), and 6(c) address hazard effects from exposure of the 
package to a fire but do not address whether hazardous effects from 
functioning of the articles or substances is confined within the 
package. PHMSA is concerned that there is a possibility that products 
classified as Division 1.4S based on behavior in a fire according to 
test procedures of Type 6(c) may still produce a hazardous effect that, 
when initiated, is not confined to a package. Initiation or ignition as 
a result of fire, after the package is degraded, may produce different 
results from functioning with the intended means of ignition or 
initiation. Knowledge of the behavior of the article or substance in 
both cases is needed to allow proper classification.
    As discussed in the comment summary in response to the NPRM, PHMSA 
is requiring the Type 6(d) test as prescribed in Section 16.7 of the 
fifth revised edition of the UN Manual of Tests and Criteria in the new 
special provision 347. For affected articles intended for 
transportation by aircraft,

[[Page 3330]]

the compliance date of this new requirement is July 1, 2011. If a 
manufacturer or approval holder of affected articles previously classed 
and approved as Division 1.4S chooses to continue offering such 
shipments as Division 1.4S material by aircraft, the articles must be 
successfully tested under Test Series 6(d) and a new approval obtained 
from PHMSA. Additionally, a previously classed and approved Division 
1.4S article that is not successfully tested under Test Series 6(d) 
must be assigned to a compatibility group other than S (e.g., B, C, or 
D) prior to being transported by aircraft. Based on knowledge that an 
article or substance will not pass the Type 6(d) test, a manufacturer 
or approval holder may choose to have a previously approved Division 
1.4S explosive reassigned to a different compatibility group based on 
existing data and recommendation by a PHMSA-approved explosives testing 
and examination facility in lieu of conducting the Type 6(d) test. For 
new Division 1.4S articles approved prior to January 1, 2012 intended 
for domestic highway or rail transportation only, the compliance date 
for testing to maintain Division 1.4S classification or reassignment to 
a higher compatibility group other than S is January 1, 2014. For 
international highway, rail and vessel transportation and domestic 
vessel transportation, the compliance date for Type 6(d) testing or 
reassignment for new and previously produced affected articles is 
January 1, 2012.
    A new special provision 349 is added and assigned to 
``Hypochlorites, inorganic, n.o.s., UN3212'' to specify that transport 
of mixtures of hypochlorite and an ammonium salt is forbidden.
    A new special provision 350 is added and assigned to ``Bromates, 
inorganic, n.o.s., UN1450'' and ``Bromates, inorganic, aqueous 
solution, n.o.s., UN3213'' to specify that transport of ammonium 
bromate and its aqueous solutions and mixtures of a bromate and an 
ammonium salt is forbidden.
    A new special provision 351 is added and assigned to ``Chlorates, 
inorganic, n.o.s., UN1461'' and ``Chlorates, inorganic, aqueous 
solution, n.o.s., UN3210'' to specify that transport of ammonium 
chlorate and its aqueous solutions and mixtures of a chlorate and an 
ammonium salt is forbidden.
    A new special provision 352 is added and assigned to ``Chlorites, 
inorganic, n.o.s., UN1462'' to specify that transport of ammonium 
chlorite and its aqueous solutions and mixtures of a chlorite and an 
ammonium salt is forbidden.
    A new special provision 353 is added and assigned to 
``Permanganates, inorganic, n.o.s., UN1482'' and ``Permanganates, 
inorganic, aqueous solution, n.o.s., UN3214'' to specify that transport 
of ammonium permanganate and its aqueous solutions and mixtures of a 
permanganate and an ammonium salt is forbidden.
    A new special provision 357 is added and assigned to the entry 
``Petroleum crude oil, UN1267'' to clarify that when transported 
internationally, petroleum crude oil containing hydrogen sulfide in 
sufficient concentration that vapors evolved from the crude oil can 
present an inhalation hazard must be transported under the entry 
``Petroleum sour crude oil, flammable, toxic, UN3494.'' As discussed in 
detail in response to comments submitted to the ANPRM, for domestic 
transportation, use of the toxic description is not required; however, 
a bulk package is required to be marked in accordance with the 
requirement of new Sec.  172.327 of the HMR. See Section 173.327 for a 
discussion of the marking requirement.
    In the August 2010 NPRM, PHMSA proposed to revise special provision 
A59 for consistency with amendments made to special provision A131 of 
the 2011-2012 ICAO Technical Instructions. Special provision A59 allows 
sterilization devices containing ethylene oxide to be offered for 
transportation and transported by air under the excepted quantity 
provisions of Sec.  173.4a of the HMR. One commenter (Andersen) 
supported the amendments to A59 but noted that the special provision 
originally appearing in the ICAO Technical Instructions (as special 
provision A131) applicable to air transport has been adopted in the UN 
Model Regulations as special provision 342 for use by other modes of 
transport. Additionally, special provision 342 is also to be 
incorporated into the IMDG Code. The commenter questioned the 
appropriateness of adopting an ``A'' prefix special provision which 
limits the special provision, to air transport only. Andersen stated:

    In the preamble to the [NPRM], on page 53085, PHMSA observes 
that ``Special provision A59 allows for sterilization devices 
containing ethylene oxide to be offered for transportation and 
transported by air (and thereby all modes) under the excepted 
quantity provisions of Sec.  173.4a'' (emphasis added) * * * 
notwithstanding PHMSA's statement in regard to the multi-modal 
applicability of this special provision, it is not at all clear from 
the wording of Sec.  172.102(c)(2) [A59] * * * that this special 
provision extends to all modes of transport.

    The commenter suggested that, in order to achieve complete 
harmonization and for greater clarity of the applicability of the 
special provision, PHMSA revise the applicability of the special 
provision to all modes and not restrict the special provision to air 
transport through the use of the ``A'' prefix as currently implemented.
    We agree. Therefore, in this final rule we are deleting Special 
provision A59 and adopting new Special provision 342 which applies 
conditions for transportation of sterilization devices containing 
ethylene oxide to all modes of transportation.
    A new Special provision A112 is added authorizing the 
transportation of certain IBCs by passenger and cargo-only aircraft 
that contain up to a maximum net quantity of 1,000 kg of an 
``Environmentally hazardous substance, solid, n.o.s. UN3077.'' This 
amendment is consistent with the authorization in the 2011-2012 ICAO 
Technical Instructions.
    In paragraph (c)(4), the Table 1 (IBC Codes) are editorially 
revised to remove UN Specifications 31A, 31B and 31N from IBC Codes 
IB4, IB5, IB6, IB7, and IB8. This revision is consistent with 
amendments to international standards and removes the specifications 
from the indicated codes in the table because IBC Codes IB4 through IB8 
are assigned to solids, whereas, UN Specifications 31A, 31B, and 31N 
are authorized for transportation of liquids in IBC Codes IB1 through 
IB3 which are assigned to liquid materials only.
    Paragraph (c)(7) outlines provisions that apply to the 
transportation of hazardous materials in UN portable tanks. Two 
commenters (DGAC, PSA) requested that PHMSA revise Sec.  172.102(c)(7) 
to allow shipment of solid materials in certain portable tanks using 
bottom outlets. PSA stated:

    At the recommendation of the United States, new provisions 
governing the use of bottom outlets on portable tanks were adopted 
in the [UN] Model Regulations * * * However, the United States does 
not follow its own recommendation in the Proposed Rule * * * To date 
* * * the HMRs flatly prohibit the use of bottom outlets for solids 
referenced in the American proposal to the U.N. In the Table of 
Portable Tank T Codes T1-22, which appears in 49 C.F.R. Sec.  
172.102(c)(7), instructions T9 and T21 indicate ``prohibited'' in 
the column designated ``bottom outlet requirements.'' The text of 
Sec.  172.101(c)(7)(ii) explains that the word ``prohibited'' in 
that column of the Table ``means bottom openings are prohibited.'' 
In the Proposed Rule, and without explanation, the agency did not 
propose to adopt its own bottom outlet provision.

    In the interest of harmonization with specific regard to the 
January 1, 2011

[[Page 3331]]

effective date for international regulations, the commenters urged 
PHMSA to adopt the provisions we successfully persuaded international 
organizations to adopt.
    We agree. In the paper submitted to the UN Sub-Committee of Experts 
(UNSCOE) on the Transport of Dangerous Goods (see UN document ST/SG/
AC.10/C.3/2007/24 available at http://www.unece.org/trans/main/dgdb/dgsubc/c32007.html), the U.S. successfully persuaded UNSCOE to adopt 
provisions authorizing the use of bottom outlets on portable tanks used 
to transport PG I solid material on the basis that (1) transport of 
these materials in portable tanks without bottom openings is 
impractical and it is virtually impossible to unload the material from 
the portable tank through top openings; and (2) there is no compelling 
safety reason to prohibit bottom openings in portable tanks suitable 
for such material when the authorized portable tanks afford a level of 
safety in transport substantially greater than that afforded by other 
packagings authorized for the material (e.g., UN1A2 removable head 
steel drums). Although PHMSA did not propose this amendment in the 
August 2010 NPRM, based on comments received and the relief provided to 
industry by authorizing an alternative method of unloading PG I solid 
material without a reduction in packaging safety, in this final rule we 
are revising Sec.  172.101(c)(7) by revising T Codes T9 and T21 to 
prohibit bottom openings for liquid only and specify applicable 
requirements for the bottom openings. The revision includes adding 
clarifying language to Sec.  172.101(c)(7)(ii) to specify the meaning 
of ``prohibited'' for liquids in the appropriate context. With regard 
to PSA's suggested revised regulatory text, we do not believe it is 
necessary to add language specifying that the bottom outlets must 
conform to 6.7.2.6.2 of the UN Model Regulations (bottom opening 
requirements for portable tanks used for solid material) because these 
provisions are dealt with under Sec.  178.275(d)(2), which we are 
referencing in the revised entries for portable tank T Codes T9 and 
T22.
    A new portable tank special provision TP36 is added authorizing the 
use of fusible elements in the vapor space of portable tanks with a 
gauge test pressure that exceeds 265 kPa (38.4 psig/2.65 bar). See 
Section 178.275 for a detailed discussion. See Section 172.101 
Hazardous Materials Table for a listing of materials assigned this 
special provision.
    A new special provision W1 is added indicating that the hazardous 
materials ``Potassium nitrate, UN1486,'' ``Sodium nitrate, UN1498,'' 
and ``Sodium nitrate and Potassium nitrate mixtures, UN1499'' are not 
subject to the HMR when transported by vessel in non-friable prills or 
granules form. The material must be accompanied by a certificate from 
an accredited laboratory stating that the product has been properly 
sampled and tested by the laboratory according to the UN Manual of 
Tests and Criteria.
Section 172.200
    Section 172.200 prescribes the applicability of shipping paper 
requirements for the transportation of hazardous materials. Paragraph 
(b)(3) is revised to remove the exceptions for ORM-D material in 
conformance with the changes made to the limited quantities 
requirements under this final rule.
Section 172.203
    Section 172.203 specifies additional hazardous materials 
description requirements on shipping papers. Paragraph (b) is revised 
to indicate that when a shipping paper is required, a limited quantity 
must be indicated as such. This revision is necessary due to the 
shipping paper exception adopted in this final rule for limited 
quantities intended for transportation by highway or rail.
Section 172.300
    Section 172.300 prescribes the applicability of the HMR marking 
requirements incorporated in subpart D of Part 172. Paragraph 
(l)(1)(ii) of Sec.  172.101 authorizes up to a one-year transition 
period for continued use of stock of pre-printed packaging marked with 
proper shipping names revised in the HMT under a rulemaking. Consistent 
with the transition period authorized in Sec.  172.101(l)(1)(ii), in 
this final rule we are amending Sec.  172.300 of the HMR to authorize 
the continued use of stock of preprinted packaging for one year from 
the date of compliance or until depleted (whichever is less) for a 
revision to a required marking. This amendment allows the continued use 
of preprinted packaging stock that is marked in accordance with the 
manner previously authorized.
Section 172.301
    Section 172.301 prescribes general marking requirements for non-
bulk packagings. In this final rule, PHMSA is amending paragraph (a) to 
clarify that a proper shipping name and identification number is not 
required to be marked on package containing only limited quantity 
material marked in accordance with Sec.  172.315(a). Additionally, it 
is amended by adding that until January 1, 2014 (January 1, 2013 if 
intended for transportation by aircraft), an identification number is 
not required to be marked on package containing only a Consumer 
commodity, ORM-D or ORM-D-AIR material, as defined in Sec.  171.8 of 
this subchapter in effect on October 1, 2010, provided the package is 
marked in accordance with Sec.  172.316.
Section 172.312
    Section 172.312 prescribes the required orientation markings for 
non-bulk packages containing liquids. PHMSA is amending paragraph 
(c)(5) to clarify that the exception applies only to a hermetically 
sealed inner packaging or receptacle not exceeding 500 mL each.
Section 172.315
    Section 172.315 specifies the markings required on a package 
containing limited quantities of hazardous materials. These new 
markings are consistent with the UN Model Regulations, ICAO TI and IMDG 
Code and are required on packages of limited quantities offered for 
transportation by highway, rail, air and vessel. Additionally, PHMSA 
received positive comments submitted in response to the ANPRM 
concerning the new marking because the requirement specifies minimum 
dimensions on each side (100 mm) that substantially increases the 
visibility of the marking when compared with the current ORM-D marking 
prescribed in Sec.  172.316 of the HMR. Commenters stated that 
increased visibility of the mark will enhance safety while reducing 
regulatory burden.
    For limited quantities intended for transportation by vessel, this 
new marking with minimum dimensions of 250 mm on each side is required 
on cargo transport units containing limited quantities and no other 
hazardous materials. For limited quantities intended for transportation 
by aircraft, the marking requirements are consistent with the 2011-2012 
ICAO TI (i.e., ``Y'' mark on a white square on point) in addition to 
any required labels.
Section 172.316
    Section 172.316 prescribes marking requirements for packages 
containing materials classed as ORM-D and ORM-D-AIR. The marking 
prescribed in this section will no longer be authorized for limited 
quantities effective January 1, 2014.
Section 172.322
    Section 172.322 prescribes marking requirements for packages 
containing marine pollutants. PHMSA is adding an

[[Page 3332]]

exception from the marking requirement in new paragraph (d)(4) for 
packages of limited quantities marked in accordance with Sec.  172.315.
Section 172.324
    Section 172.324 prescribes marking requirements for packages 
containing hazardous substances in non-bulk packagings. PHMSA is 
revising paragraph (b) for packages containing hazardous substances 
marked in accordance with the limited quantity marking prescribed in 
Sec.  172.315.
Section 172.326
    Section 172.326 prescribes the marking requirements for portable 
tanks. In this final rule, we are revising paragraph (a) to align with 
the IMDG Code the minimum height for a proper shipping name marked on a 
portable tank to 65 mm when offered for transportation and transported 
by vessel. This amendment is in response to a revision made in 
Amendment 35-10 of the IMDG Code.
    One commenter (Arkema) requests that we allow a one year transition 
period from the publication of the final rule to allow for depletion of 
label inventory and/or restenciling of portable tanks. We agree that 
there should be a transition period and note that, in this final rule, 
we are implementing a delayed compliance date of January 1, 2012, which 
is one year from the effective date of the rule, unless otherwise 
specified in provisions adopted or revised in this final rule.
Section 172.327
    New section 172.327 specifies the marking required for a bulk 
packaging containing petroleum crude oil to warn of the potential toxic 
inhalation hazard from vapors evolved from hydrogen sulfide present in 
the crude oil. PHMSA proposed to require placement of the marking used 
for toxic materials under the Globally Harmonized System of 
Classification and Labeling of Chemicals (GHS) in the immediate 
vicinity of any location on a bulk packaging that could pose a health 
risk to transportation workers if exposed to hydrogen sulfide vapors 
emitted from that location, such as loading heads and manholes. This 
proposed hazard communication marking requirement is applicable to bulk 
packagings in domestic transportation only. The new hazardous materials 
description for ``Petroleum sour crude oil, flammable, toxic, UN3494'' 
added to the HMT must be used for international transportation of 
petroleum crude oil with hydrogen sulfide in sufficient concentration 
that vapors evolved from the crude oil present an inhalation hazard 
(for both bulk and non-bulk packagings).
    One commenter (AAR) expressed concern that this new marking 
requirement would place an undue burden on rail carriers with regard to 
inspection requirements under Sec.  174.9 of the HMR. The commenter had 
concerns regarding the safety of rail carrier employees having to climb 
tank cars to determine whether markings are present or correct. AAR 
stated:

    [We] we would not oppose the proposed marking if it were made 
clear that railroads have no obligation to inspect for markings. 
Accordingly, [we suggest] amending [Sec.  173.127 to indicate] 
carrier personnel are not required to inspect for markings that 
would not be visible or legible from the ground.

    We agree, although we do not believe a regulatory revision is 
warranted. Section 174.9 requires a rail carrier to inspect each rail 
car containing a hazardous material, at ground level, for required 
markings, labels, and placards, etc. This requirement already limits 
the inspection to ground level and predisposes the carrier from having 
to climb onto a rail car to inspect for hazard communications. As 
indicated in the comments by AAR, the intent of this marking is to 
alert hazmat employees who may be exposed to hydrogen sulfide vapors 
during a loading or unloading operation to a potential hazard and not 
to communicate the hazard for emergency response purposes. Thus, 
carriers will not be obligated to inspect for markings placed in the 
vicinity of tank car openings on a rail car that are not readily 
visible or legible from ground level.
    Based on comments received, we are revising our proposed 
requirements to authorize an alternative marking to the GHS toxic 
material pictogram. See the Sections II.C and III.A.7 discussion of the 
classification of petroleum sour crude oil.
Section 172.500
    Section 172.500 specifies the applicability of placarding 
requirements to certain materials. PHMSA is amending paragraph (b)(3) 
to clarify that limited quantities marked in accordance with revised 
Sec.  172.315 of the HMR are not subject to placarding requirements.
Section 172.502
    Section 172.502 specifies prohibited and permissive placarding 
requirements. In this final rule, PHMSA is revising the exceptions 
provided in paragraph (b)(2) to include the petroleum sour crude oil 
marking and the limited quantity marking in Sec. Sec.  172.315 and 
172.327 of the HMR, respectively.

Part 173

Section 173.4
    Section 173.4 prescribes the requirements for small quantities of 
hazardous materials offered for transportation and transported by 
domestic highway or rail. PHMSA is revising paragraph (a) and adding 
new paragraph (a)(1)(v) to allow Division 2.2 (non-flammable, non-
poisonous, compressed gas) material without a subsidiary hazard (except 
for aerosols) without applying for an approval from the Associate 
Administrator as prescribed under paragraph (c) of this section. Other 
Class 2 materials, including Division 2.2 aerosols, will still require 
approval under Sec.  173.4(c) of the HMR. These amendments are 
consistent with the authorization under Sec.  173.4a(b)(1) for Division 
2.2 gases without a subsidiary hazard in addition to the new 
restriction to exclude aerosols from authorized materials in Sec.  
173.4a of the HMR. See Section 173.4a for a discussion of revisions for 
excepted quantities of hazardous materials.
Section 173.4a
    Section 173.4a prescribes the requirements for excepted quantities 
of hazardous materials offered for transportation and transported by 
all modes, domestic or international. PHMSA is amending paragraph (a) 
by adding a new paragraph (a)(4) regarding pressure differential 
capability for packages intended for transportation by aircraft in 
accordance with Sec.  173.27(c) of the HMR. PHMSA is also amending 
paragraph (b)(1) to clarify that the authorization for Division 2.2 
(non-flammable, non-poisonous, compressed gas) excludes aerosols as an 
excepted quantity material. Such articles are authorized as a limited 
quantity under both domestic and international standards. Additionally, 
PHMSA is revising paragraph (b)(5) to add polyester resin kits to the 
types of Division 5.2 (organic peroxide) material authorized as an 
excepted quantity and is revising paragraph (d)(3) by correcting the 
outer packaging aggregate quantity limit for Division 5.2 liquids from 
250 mL to 500 mL. Lastly, PHMSA is adding a new paragraph (g)(3) that 
requires when packages of excepted quantities (see the Section 173.25 
discussion) are contained in an overpack, and the package markings 
required by this section are not visible inside the overpack, the 
excepted quantities marking must also be placed on the

[[Page 3333]]

overpack. Additionally, an overpack containing packages of excepted 
quantities is not required to be marked with the word ``OVERPACK.''
Section 173.4b
    Section 173.4b prescribes the requirements for de minimis 
quantities of hazardous materials offered for transportation and 
transported by all modes, domestic or international. Consistent with 
the international standards, PHMSA is adding a new paragraph (b) to 
except non-infectious specimens (e.g., museum specimens) preserved with 
small amounts of certain Class 3 (flammable liquid) materials for 
scientific purposes from the requirements of the HMR. This amendment is 
consistent with previous interpretations we have issued on this matter 
indicating these specimens do not pose a risk to safety during the 
course of transportations.
    One commenter (AVMA) expressed support for the adoption of this 
exception as essential to the conduct of professional work of 
veterinarians. Therefore, in this final rule, we are adopting the 
exception from full regulation under the HMR for non-infectious 
specimens preserved with small amounts of certain Class 3 (flammable 
liquid) material for scientific purposes.
Section 173.25
    Section 173.25 prescribes the requirements for certain authorized 
packagings and overpacks. Consistent with the international standards, 
PHMSA is requiring an overpack containing packages of limited quantity 
material marked with the new limited quantities marking required by 
this final rule (see the Section 172.315 discussion) to be marked with 
the word ``OVERPACK'' if the markings are not visible, in addition to 
all other required package markings. This mark is an indication that 
the packages contained within the overpack are in accordance with the 
HMR. Additionally, for excepted quantities (see the Section 173.4a 
discussion) where the required package markings are not visible inside 
an overpack, the excepted quantities marking must also be placed on the 
overpack. An overpack containing packages of excepted quantities is not 
required to be marked with the word ``OVERPACK.''
Section 173.27
    Section 173.27 prescribes the general requirements for packaging 
offered or intended for air transportation. In this final rule, PHMSA 
is amending paragraph (f) by adding a new Table 3 that outlines the 
requirements for limited quantities intended for air transportation 
consistent with the 2011-2012 ICAO Technical Instructions, where 
appropriate. See the limited quantity, consumer commodity and ICAO 
Technical Instructions alignment NPRM comment discussion in Section 
III.A.5 of this rule.
Section 173.40
    Section 173.40 specifies the general packaging requirements for 
toxic materials packaged in cylinders. PHMSA is amending paragraph 
(c)(1) concerning closure requirements by requiring the valve 
connections on UN Specification cylinders to be made by a taper thread 
or some other means in accordance with ISO Standard 10692-2:2001.
Section 173.58
    Section 173.58 outlines the assignment of class and division for 
new explosives. Based on a recommendation from comments provided by 
IME, we are revising paragraph (a)(5) to include a reference to the 
Type 6(d) test for determination of Division 1.4S classification for 
consistency with the adoption of the new test.
Section 173.59
    Section 173.59 provides definitions of explosive terms that are 
intended for information only. The UN Committee of Experts (COE) 
recently defined the term ``phlegmatized'' to meaning the addition of a 
substance to an explosive to enhance its safety in handling and 
transport. One commenter indicated support for adoption of the proposed 
definition of ``phlegmatized,'' therefore, in this final rule PHMSA is 
adopting the definition in the HMR as proposed.
Section 173.63
    Section 173.63 specifies packaging exceptions for limited 
quantities of certain Division 1.4S explosive articles authorized for 
reclassification and transport as ORM-D material. Prior to offering for 
transportation by aircraft, ``Cartridges, power devices, ORM-D-AIR'' 
(UN0323), must have been successfully tested in accordance with the new 
UN Test Series Type 6(d) test beginning July 1, 2011. See the Section 
172.102, Special Provision 347 discussion. This requirement is a 
condition for the continuation of a Division 1.4S classification and 
for reclassification to ORM-D for limited quantities of such articles 
intended for transportation by international highway, rail and vessel 
and domestic vessel effective January 1, 2012. Limited quantities of 
such articles approved as Division 1.4S prior to January 1, 2012, may 
continue to be reclassed as ORM-D and offered for domestic highway and 
rail transportation only until January 1, 2014.
Section 173.120
    Section 173.120 defines Class 3 (flammable liquid) material. PHMSA 
is revising paragraph (c) to add new testing methods for determining 
the flash point of a liquid. See Section 171.7 for a listing of 
materials incorporated by reference pertaining to Sec.  173.120.
Section 173.121
    Section 173.121 prescribes the packing group assignment for 
flammable liquids. The HMR do not specify a test method for determining 
the boiling point of a liquid which may be necessary for liquids with 
very low flash points. PHMSA is revising paragraph (a) to add new 
testing methods for determining the boiling point of a liquid. See 
Section 171.7 for a listing of materials incorporated by reference 
pertaining to Sec.  173.121.
Section 173.124
    Section 173.124 defines Class 4 material. For consistency with a 
revision adopted in the UN Model Regulations, PHMSA is amending the 
definition of ``self-heating'' in Sec.  173.124(b)(2) of the HMR to 
read: ``Self-heating of a substance is a process where the gradual 
reaction of that substance with oxygen (in air) generates heat. If the 
rate of heat production exceeds the rate of heat loss, then the 
temperature of the substance will rise which, after an induction time, 
may lead to self-ignition and combustion.''
Section 173.137
    Section 173.137 establishes test criteria and packing group 
assignments for Class 8 (corrosive) material. Since 1993, PHMSA has 
authorized under the terms of a special permit (i.e., DOT-SP 10904) an 
in vitro test method (available commercially as Corrositex[reg]) as an 
alternative form of testing to that specified in the HMR, which is 
based on live animal test results, to determine the corrosivity of 
certain materials. Materials authorized for analysis using the 
alternative test method include acids (and their derivatives), acyl 
halides, alkylamines and polyalkylamines, bases, chlorosilanes, metal 
halides, and oxyhalides.
    The UN COE recently recognized and adopted in vitro test methods in 
the UN Model Regulations as an alternative form of testing to that 
specified in OECD Guideline for Testing of Chemicals, Number 404, 
``Acute Dermal Irritation/

[[Page 3334]]

Corrosion.'' The following alternative in vitro test methods include 
OECD Guidelines for the Testing of Chemicals:
     No. 430, ``In Vitro Skin Corrosion: Transcutaneous 
Electrical Resistance Test (TER)'' (2004);
     No. 431, ``In Vitro Skin Corrosion: Human Skin Model 
Test'' (2004); and
     No. 435, ``In Vitro Membrane Barrier Test Method for Skin 
Corrosion'' (2006).
    A positive test result under in vitro methods 430 and 431 may be 
used to determine corrosivity for transportation purposes but cannot be 
used to determine the PG assignment. A negative result for corrosivity 
under in vitro methods 430 and 431 can preclude further testing to 
determine PG assignment using method 404, the current OECD Guideline 
involving in vivo testing, or method 435, the newly adopted OECD 
Guideline involving in vitro testing.
    Based on the adoption of three new OECD guidelines for the in vitro 
testing of materials for corrosivity in the UN Model Regulations and 
through encouragement from PETA to adopt these new test methods in a 
petition for rulemaking (P-1550), we proposed to adopt such guidelines 
as matter incorporated by reference (IBR) in Sec. Sec.  171.7 and 
173.137 of the HMR.
    In response to our proposal to incorporate several in vitro test 
methods for determination of corrosivity, PHMSA has received over 900 
comments supporting the proposal, including a comment from PETA. We 
received no opposition. Therefore, we are adopting the OECD Guideline 
Test Nos. 430, 431, and 435, and revising Test No. 404 as proposed. 
Further, PETA urged PHMSA to facilitate access to DOT-SP 10904 through 
our Web site until such a time that this final rule becomes effective, 
and requested that PHMSA remove letters of interpretation that they 
believe recommend the use of in vivo testing even though alternative in 
vitro testing is available.
    With regard to PETA's additional requests, they are beyond the 
scope of this rulemaking. However, we note that in prior correspondence 
with PETA, PHMSA has indicated that information about DOT-SP 10904 can 
be obtained by entering ``Corrositex'' in the search feature of the 
PHMSA Office of Hazmat Safety Web site. Also, the special permit may be 
accessed by entering ``10904'' in the search feature on our special 
permits Web site or by conducting a group number search.
    We agree with PETA that non-live animal testing should be used 
where available and encourage shippers to use the in vitro test methods 
to determine the classification of a material as corrosive and 
assignment of a packing group. We also remind shippers that historical 
data may also be used to classify a material in accordance with Sec.  
173.136(c). Thus, in this final rule we are revising Sec.  173.136(a) 
to codify the authorization to use in vitro test methods and to 
highlight the availability of classifying a material based on 
historical data.
Sections 173.150, 173.151, 173.152, 173.153, 173.154 and 173.155
    Sections 173.150 through 173.155 prescribe the exceptions for 
certain Class 3, 8 and 9 and Division 4.1, 4.2, 4.3, 5.1, 5.2, 6.1 
hazardous materials under the HMR. In this final rule, PHMSA is 
revising each of these sections to recognize the UN Model Regulations 
and IMDG Code package quantity limits for the highway, rail, and vessel 
transportation of limited quantities. No limited quantity limits 
decrease and two increase slightly to maintain alignment with the 
international standards for transport by other than aircraft. 
Additionally, the packaging provisions for ``Polyester resin kits'' are 
removed from Sec.  173.152, as proposed, and placed in new Sec.  
173.165 for clarity.
    When PHMSA lowered the quantity limits for Division 6.1 (poisonous) 
materials of PG II (primary or subsidiary) authorized as a limited 
quantity in a final rule published under Docket HM-215G (70 FR 34065, 
June 13, 2005), it did not authorize the labeling exception for such 
packages when intended for transportation by highway, rail and vessel, 
nor did it authorize renaming and reclassification as ``Consumer 
commodity, ORM-D'' for such materials. In this final rule, except for 
transportation by aircraft, we are authorizing the labeling exception 
for packages of limited quantity material with a Division 6.1, PG II 
primary or subsidiary hazard and, until December 31, 2013, we are 
authorizing renaming and reclassification as ``Consumer commodity, ORM-
D''. Additionally, until December 31, 2012, a consumer commodity as 
defined in Sec.  171.8 in effect on October 1, 2010 may continue to be 
packaged, reclassed and marked ``ORM-D-AIR'' either in accordance with 
the new Table 3 of Sec.  173.27(f) or Sec. Sec.  173.150 through 
173.155 and 173.306, as applicable. PHMSA fully believes this eventual 
alignment with international standards will improve clarity, promote 
regulatory compliance, reduce employee training costs and enhance 
safety overall.
Section 173.161
    Section 173.161 prescribes packaging requirements for chemical kits 
and first aid kits containing small amounts of hazardous materials. In 
this final rule, PHMSA is editorially revising the section. In 
addition, PHMSA is authorizing transport of dry ice in accordance with 
Sec.  173.217 in packaging authorized under this section when used as a 
refrigerant for the contents of a kit.
Section 173.165
    A new section 173.165 is added to prescribe packaging and other 
requirements for ``Polyester resin kits, UN3269'' formerly contained in 
Sec.  172.102, special provision 40 and Sec.  173.152(b)(4) of the HMR. 
This amendment is intended to provide clarification of existing 
requirements while also harmonizing the HMR with international 
standards.
Section 173.167
    A new section 173.167 is added to indicate authorized materials and 
quantity limits for articles and substances that may be described as 
``ID8000, Consumer commodity,'' when intended for transportation by all 
modes of transport provided all or some of the transportation is by 
aircraft. Such articles and substances eligible for classification or 
reclassification to Class 9 are Class 2 materials (non-toxic aerosols 
only), Class 3 materials (Packing Group II and III only), Division 6.1 
(Packing Group III only), UN/NA3077, UN/NA3082, and UN3175, provided 
such materials do not have a subsidiary risk and are authorized aboard 
a passenger-carrying aircraft. Inner and outer packaging quantity 
limits are based on Packing Instruction Y963 of the 2011-2012 ICAO TI. 
Specification outer packagings are not required under the conditions 
prescribed in this section. Additionally, the pressure differential 
capability of the inner packagings of a combination packaging intended 
to contain liquids is reduced from 95 kPa to 75 kPa for materials 
offered for transportation and transported by aircraft under the 
provisions of this section.
Section 173.220
    Section 173.220 provides exceptions from regulation under the HMR 
for the transport of internal combustion engines, self-propelled 
vehicles, mechanical equipment containing internal combustion engines, 
and battery-powered vehicles or equipment. This section is revised to 
include engines, vehicles, and equipment powered by fuel cells 
consistent with

[[Page 3335]]

similar provisions under international standards.
Section 173.225
    Section 173.225 specifies packaging requirements and other 
provisions for organic peroxides. When the Sec.  172.101 HMT specifies 
this section, the organic peroxide must be packaged and offered for 
transportation in accordance with the provisions of this section. Each 
packaging must also conform to the general requirements of Subpart B of 
Part 173 and to the applicable requirements of Part 178 of the HMR. 
Specifically, organic peroxides that require temperature control are 
subject to Sec.  173.21(f). When an IBC or bulk packaging is authorized 
and meets the requirements of paragraph (f) or (h) of Sec.  173.225, 
respectively, lower control temperatures than those specified for non-
bulk packaging may be required. An organic peroxide not identified in 
paragraph (c), (e), or (g) of Sec.  173.225 by technical name, or not 
assigned to a generic type in accordance with paragraph (b)(3) of this 
section, must conform to the requirements in paragraph (c) of Sec.  
173.128.
    The Organic Peroxides Table specifies by technical name those 
organic peroxides that are authorized for transportation and not 
subject to the approval provisions of Sec.  173.128. An organic 
peroxide identified by technical name is authorized for transportation 
only if it conforms to all applicable provisions of the table. In this 
final rule, PHMSA is amending the Organic Peroxide Table in Sec.  
173.225(c)(8) by adding a new entry and revising current entries. We 
are revising an entry to the Organic Peroxide IBC Table in paragraph 
(e) of this section.
    The following entries in the Organic Peroxide Table are being 
revised:

----------------------------------------------------------------------------------------------------------------
 
----------------------------------------------------------------------------------------------------------------
UN3106..............................................  Di-(2-tert-butylperoxyisopropyl) benzene(s).
Exempt..............................................   Di-(2-tert-butylperoxyisopropyl) benzene(s).
UN3105..............................................   2,5-Dimethyl-2, 5-di-(tert-butyl peroxy) hexane.
----------------------------------------------------------------------------------------------------------------

    The following entry is added to the Organic Peroxide Table:

----------------------------------------------------------------------------------------------------------------
 
----------------------------------------------------------------------------------------------------------------
UN3103..............................................  2,5-Dimethyl-2, 5-di-(tert-butyl peroxy) hexane.
----------------------------------------------------------------------------------------------------------------

    One commenter (Arkema) requested that PHMSA provide a packing 
method exception for domestic transportation of greater than 90% 
concentrations of this material based on a history of safe 
transportation. The proposed revision to this entry changed the packing 
method for this material in concentrations of 90-100% from OP7 to OP5, 
reducing the maximum quantity per package from 60 L to 30 L per 
package. Arkema stated:

    [We ship] a 97% solution in 100 pound drums. Since August 2005 
we have shipped [approximately] 1,800,000 pounds. We have had only 
one incident in the 5 year time period. This incident was the result 
of a pallet nail puncture. We suggest that a note be added to column 
(8) for domestic shipments [that] OP7 is authorized.

    We disagree. The UN Committee of Experts adopted the 
reclassification of 90-100% concentrations of 2, 5-Dimethyl-2, 5-di-
(tert-butylperoxy) hexane, which entails the more conservative packing 
method OP5, based on a proposal submitted by the German competent 
authority. Available industry test data from results on this material 
at concentrations greater than 90% using the E1 Koenen test in the UN 
Manual of Tests and Criteria varies from 1.5-2.0 mm. Based on 
differences in industry test results, the German competent authority 
conducted a number of E1 Koenen tests on various concentrations of 2, 
5-Dimethyl-2, 5-di-(tert-butylperoxy) hexane exceeding 90%. Their 
conclusion was that the limiting diameter is 2.0 mm at concentrations 
above 90%, and therefore, they proposed a reclassification from an 
``Organic Peroxide, Type D, liquid, UN3105'' to an ``Organic Peroxide, 
Type C, liquid, UN3103'' for 90-100% concentrations of 2, 5-Dimethyl-2, 
5-di-(tert-butylperoxy) hexane to the UNSCOE (see UN working document 
ST/SG/AC.10/C.3/2008/66 available on the UNSCOE Web site).
    We applaud Arkema's safe record of transportation using packing 
method OP7 for a greater than 90% concentration of material. However, 
based on data provided by the German competent authority indicating a 
more conservative classification, in this final rule, we are keeping 
this entry as proposed. We invite Arkema to submit test results for 
their 97% solution of 2, 5-Dimethyl-2, 5-di-(tert-butylperoxy) hexane 
should the results indicate a classification that differs from the 
entry adopted in this final rule.
    The following entry in the Organic Peroxide IBC Table is being 
revised to authorize a 31H2 freestanding, rigid plastic IBC:

----------------------------------------------------------------------------------------------------------------
 
----------------------------------------------------------------------------------------------------------------
UN3109..............................................  Peroxyacetic acid, stabilized, not more than 17%.
----------------------------------------------------------------------------------------------------------------

Section 173.230
    Section 173.230 prescribes the requirements for fuel cells offered 
for transportation by all modes. In paragraph (g), PHMSA proposed to 
allow only those fuel cells containing flammable liquids and corrosive 
materials to be transported as a limited quantity by aircraft. In 
paragraph (h), PHMSA also proposed prohibiting the reclassification to 
``Consumer commodity, ORM-D-AIR'' for transportation by aircraft. 
Several commenters (BIC, COSTHA, DGAC, IATA, LSI, Signa, Trulite, 
USFCC) expressed strong disapproval to not extending the limited 
quantity provisions to fuel cell cartridges containing either Division 
2.1 (flammable) gas or water-reactive solids. They noted that the only 
difference between authorizing and not authorizing these materials as 
limited quantities is the required use of UN specification packaging 
and that PHMSA offers no safety rationale for this exclusion as the 
fuel cell cartridges themselves are subject to much more stringent 
construction, testing, and packaging requirements than for similar 
articles (e.g., aerosols).
    We agree. In this final rule, based on comments received, we are 
authorizing the transportation of flammable gas and water-reactive 
solid fuel cell cartridges as limited quantities in addition to 
authorizing their transport as consumer commodities (except for 
transportation

[[Page 3336]]

by aircraft) if all conditions for limited quantity provisions are met.
Section 173.301b
    Section 173.301b prescribes general requirements for shipment of UN 
pressure receptacles. PHMSA is revising paragraph (c)(2)(iii) to 
indicate that valve protection requirements for metal hydride storage 
systems are specified in ISO 16111. Additionally, we are revising 
paragraph (e) regarding the integrity of UN pressure receptacles used 
for pyrophoric gases or flammable mixtures of gases containing more 
than 1% pyrophoric compounds in accordance with the sixteenth revised 
edition of the UN Model Regulations.
Section 173.306
    Section 173.306 prescribes the requirements for limited quantities 
of compressed gases. PHMSA is revising paragraph (h) to clarify that, 
except for transportation by aircraft, lighter refills in the ORM-D 
hazard class are eligible for the exceptions in paragraph (i) of this 
section and in Sec.  173.156. Additionally, PHMSA is revising paragraph 
(i) of the section to recognize the new marking for limited quantities 
of such materials and to provide a transitional period for the eventual 
elimination of the ORM-D hazard class. PHMSA is also editorially 
revising paragraph (l) for clarity.
Section 173.307
    Section 173.307 establishes exceptions for compressed gases. In 
this final rule, PHMSA is adding certain types of light bulbs to the 
section provided they are packaged appropriately so that if a bulb 
ruptures all pieces are contained within the package.
Section 173.311
    PHMSA is adding a new Sec.  173.311 to prescribe the packaging 
requirements for ``Metal hydride storage systems, UN3468'' used for the 
transport of hydrogen as proposed. A metal hydride storage system is a 
single complete hydrogen storage system that includes a receptacle, 
metal hydride, a pressure relief device, a shut-off valve, service 
equipment and internal components.
    The HMR do not prescribe specific packaging or shipping methods for 
metal hydride storage systems containing hydrogen. However, PHMSA has 
issued a number of special permits to allow the use of these systems 
for transport. The UN Model Regulations, in new Packing Instruction 
P205, prescribe standards for the construction, qualification, marking 
and requalification of such systems and are the basis for the new HMR 
requirements. Some amendments in new Sec.  173.311 include:
     Application to transportable metal hydride storage systems 
with pressure receptacles not exceeding 150 liters in water capacity 
and having a maximum developed pressure not exceeding 25 MPa.
     Requirement that transportable metal hydride storage 
systems be designed, constructed, initially inspected and tested in 
accordance with ISO standard 16111:2008, ``Transportable gas storage 
devices--Hydrogen absorbed in reversible metal hydride,'' as authorized 
under Sec.  178.71(f) (formerly reserved).
     Requirement that steel pressure receptacles or composite 
pressure receptacles with steel liners be marked in accordance with 
Sec.  173.301b(f) of the HMR, which specifies that a steel UN pressure 
receptacle bearing an ``H'' mark must be used for hydrogen bearing 
gases or other gases that may cause hydrogen embrittlement.
     Requirement of a requalification interval of no more than 
five years as specified in Sec.  180.207 of the HMR in accordance with 
the requalification procedures prescribed in ISO 16111.
Section 173.322
    Section 173.322 prescribes various packaging methods for ethyl 
chloride. In this final rule, PHMSA is adopting the amended provisions 
from packaging instruction P200 of the UN Model Regulations for ethyl 
chloride in a new paragraph (e). This new packaging method authorizes 
ethyl chloride in capsules not exceeding 150 g of gas each, closed with 
a secondary means applied, and placed in a strong outer packaging not 
to exceed 75 kg gross mass.

Part 175

Section 175.8
    Section 175.8 provides exceptions from certain regulations for air 
carrier operator equipment and items of replacement. PHMSA is revising 
paragraph (b)(3) to clarify that transportation of alcoholic beverages, 
perfumes, colognes, and liquefied gas lighters carried aboard a 
passenger-carrying aircraft by an operator must be for use or sale of 
those items on that specific aircraft.
    Two commenters (AA, COSTHA) requested that PHMSA align paragraph 
(b)(3) with the ICAO TI to permit onboard use of aerosols. COSTHA 
noted:

    A number of carriers currently are required to obtain a special 
permit to transport aerosols in Division 2.2, specifically for the 
dispensing of whipped cream or other food products * * * We believe 
if this list was amended by including ``aerosols'' this issue would 
be resolved.
    We agree. Therefore, in this final rule we are revising paragraph 
(b)(3) to authorize use of Division 2.2 aerosols to dispense food 
products.
Section 175.9
    Section 175.9 prescribes the applicability of the HMR to special 
aircraft and rotocraft operations. This section also prescribes the 
conditions under which certain operations may be performed in 
accordance with 14 CFR and 49 CFR (e.g., avalanche and weather 
control). In this final rule, PHMSA is emphasizing that rotocraft 
operations are fully subject to both sets of regulations.
    One commenter suggested revising paragraph (b)(6) to provide 
clarity. IME stated:

    This suggested language is consistent with [Sec. ] 177.835(g), 
which addressed the identical compatibility issue between explosives 
and detonators that are transported on the same conveyance. In 
addition, use of the terms ``dynamite'' and ``blasting caps'' 
without the additional reference to Division 1.1, 1.2, and 1.3 
material could lead to the unintentional misinterpretation or 
misapplication of the rule.

    We agree. Based on the comment provided, we are revising Sec.  
173.59(b)(6) to provide clarification.
Section 175.10
    Section 175.10 specifies the conditions for which passengers, crew 
members or an operator may carry hazardous materials aboard an 
aircraft. PHMSA is adding a new paragraph (a)(17) to permit a mobility 
aid such as a wheelchair, containing a lithium ion battery, to be 
transported in accordance with the exceptions provided in this section. 
A wheelchair or other mobility aid that contains a lithium metal 
battery is not permitted aboard a passenger-carrying aircraft. As a 
result of this amendment, current paragraph (a)(17) is redesignated as 
paragraph (a)(18) and current paragraph (a)(18) is redesignated as 
paragraph (a)(19).
    Three commenters (IATA, PRBA, Scoot) supported our proposal to add 
a new paragraph providing an exception for wheelchairs or other 
mobility aids containing a lithium ion battery, but requested that for 
consistency, we further align with the ICAO TI and accommodate carriage 
of these items by disabled passengers by allowing carriage in the 
aircraft cabin. For instance, Scoot shared:

    Our mobility scooter [is] designed to fold up and be stowed in 
the passenger cabin

[[Page 3337]]

* * *. They are often small enough to fit in the overhead bin. [T]he 
lithium-ion batteries are removed and hand-carried by the passenger 
in the same manner as * * * lithium-ion batteries used for consumer 
electronics.

    PRBA expressed disappointment that PHMSA did not address 
authorizing passenger transport of certain medical devices powered by 
lithium metal batteries in this final rulemaking. We recognize the need 
for persons with medical disabilities to be able to carry devices 
powered by lithium metal batteries aboard a passenger-carrying 
aircraft. However, such a provision will be addressed in a separate 
rulemaking.
    Paragraph (a)(19) is being revised to allow passengers and crew 
members to place certain spare fuel cell cartridges in checked baggage. 
This exception currently does not apply to Divisions 2.1 or 4.3 
materials contained in spare fuel cell cartridges. Although the ICAO TI 
only restricts spare fuel cell cartridges containing Division 4.3 
liquid materials from checked baggage, PHMSA strongly believes that the 
restriction must also include spare cartridges containing Division 2.1 
materials. Thus, PHMSA proposed to allow spare fuel cell cartridges 
containing flammable and corrosive liquids in checked baggage while 
continuing to require spare fuel cell cartridges containing Division 
2.1 and 4.3 materials to be carried aboard an aircraft in carry-on 
baggage only.
    One commenter (ALPA) supported our position while several 
commenters (COSTHA, DGAC, IATA, JEMA, PRBA, TAEC, Trulite, USFCC) 
voiced strong opposition to our proposal to limit fuel cell cartridges 
permitted in checked baggage to those with flammable liquid or 
corrosive liquid fuels. As several commenters indicated, PHMSA did not 
provide data or analysis supporting the proposal, while tests performed 
at the FAA Technical Center on fuel cell cartridges containing 
flammable liquid material indicated that in the case of a fire 
involving these materials, the fire can be readily extinguished with 
current fire suppression systems onboard an aircraft.
    Because Division 2.1 flammable gases are generally prohibited in 
air transportation on a passenger-carrying aircraft as cargo and due to 
the questionable integrity of such articles when packed in a 
passenger's checked baggage, PHMSA is adopting the prohibition in 
checked baggage of fuel cell cartridges containing Division 2.1 
flammable gases and Division 4.3 solid dangerous when wet materials as 
proposed.
Section 175.25
    PHMSA currently requires operators to provide certain information 
to passengers regarding what hazardous materials they may check-in or 
carry-on a flight. Effective January 1, 2013, this information is to be 
provided at points of ticket sale and at automated or remote passenger 
check-in. Consistent with the ICAO TI, these amendments will require a 
passenger to acknowledge such limitations before a ticket purchase and 
automated or remote check-in can be finalized. PHMSA believes these 
amendments only clarify existing regulatory requirements in Sec.  
175.25 that have not been updated due to changing technologies used by 
air carriers to either sell tickets (Internet) or check-in passengers 
(automated kiosks). Additionally, these amendments provide air carriers 
greater flexibility in how the information they are required to provide 
passengers on hazardous materials is disseminated to them.
Section 175.30
    Section 175.30 prescribes inspection procedures for operators. 
PHMSA is revising paragraph (e) regarding overpack marking requirements 
for packages of limited and excepted quantities offered for 
transportation by aircraft.
Section 175.75
    Section 175.75 prescribes quantity limitations and cargo location 
requirements for hazardous materials transported by aircraft. PHMSA is 
revising paragraph (e) to correct an inadvertent cargo compartment 
restriction for passenger-authorized materials carried aboard a cargo-
only aircraft published in a final rule under Docket HM-215J (74 FR 
2267, January 14, 2009). PHMSA is also revising paragraph (f) Quantity 
and Loading Tables for clarity.
    Several commenters (ALPA, COSTHA, PRBA, UPS) objected to our 
inclusion of limitations on the stowage of lithium batteries in Sec.  
175.75 of the HMR and strongly urged that the limitations be removed 
from this rulemaking and addressed in a separate lithium battery 
rulemaking such as HM-224F. We agree. All reference to lithium 
batteries in our revisions to Sec.  175.75 are removed from this 
rulemaking.
    One commenter (UPS) fully supported our proposed clarification of 
the use of the Class C cargo compartment for shipments of material 
eligible for passenger aircraft under Sec.  175.75(d); however, UPS did 
recommend an additional revision for clarity. Therefore, in this final 
rule we are revising paragraph (d) further to incorporate a second note 
into the table to clarify that for cargo-only aircraft, packages 
required to be loaded in a position considered accessible include those 
loaded into a Class C cargo compartment.
    Several commenters requested that PHMSA offer the same exception 
from the loading restrictions in Sec.  175.75 for limited quantity 
packages as are currently authorized for Class 9 and ORM-D-AIR 
materials. We agree that such packages should be afforded the same 
exceptions from the loading restrictions of Sec.  175.75 as ORM-D-AIR 
materials and are revising the section accordingly.
Section 175.78
    Section 175.78 prescribes the stowage compatibility of hazardous 
materials offered for transportation by aircraft. PHMSA is revising 
paragraph (c)(4)(iii) to specify that, except as provided in paragraph 
(c)(4)(iv) of Sec.  175.78, Division 1.4B explosive materials may only 
be stowed together with Division 1.4S explosive materials. This 
revision is in accordance with an amendment made in the 2011-2012 ICAO 
Technical Instructions.

Part 176

Section 176.2
    Section 176.2 establishes definitions specific to the 
transportation of hazardous materials by vessel. PHMSA is revising the 
definition for ``Cargo transport unit'' to include a multiple-element 
gas container or MEGC.
Section 176.63
    Section 176.63 sets forth and describes the basic physical 
requirements for authorized stowage locations of hazardous materials on 
board vessels. PHMSA is amending paragraph (f)(2) by removing reference 
to the specific year of SOLAS, Chapter II-2/Regulation 19 (i.e., 1974, 
as amended) for consistency with the manner in which IBR material is 
indicated throughout the HMR in outlying sections.
Section 176.76
    Section 176.76 prescribes certain requirements for transport 
vehicles, freight containers, and portable tanks containing hazardous 
materials transported by vessel. In this final rule, we are revising 
paragraph (a)(9) to require that when security devices, beacons or 
other tracking or monitoring equipment are used, they must be securely 
installed and must be of a certified safe type for the hazardous

[[Page 3338]]

materials that will be carried within the freight container or 
transport vehicle.
Section 176.84
    Section 176.84 outlines additional requirements for stowage and 
segregation of hazardous materials transported by cargo and passenger 
vessels. In this final rule, PHMSA is removing the redundant stowage 
code 143. This provision is currently assigned to UN1259, UN2845, 
UN3194, UN3392, and UN3394, and prohibits the carriage of the materials 
aboard a vessel transporting Class 1 (explosive) material (except for 
explosives of Division 1.4S). See Section 172.101 Hazardous Materials 
Table for the amendment that adds stowage code 78 to the above 
materials of extreme flammability. Such materials are now required to 
be ``separated longitudinally by an intervening complete compartment or 
hold from explosives'' based on amendments adopted in the IMDG Code.
Section 176.142
    Section 176.142 prescribes the requirements for hazardous materials 
of extreme flammability transported on the same vessel as Class 1 
(explosive) materials. In this final rule, PHMSA is deleting this 
section as the restriction no longer exists. Hazardous materials of 
extreme flammability are no longer prohibited from stowage on the same 
vessel as explosives. For entries previously affected by this section, 
the most restrictive stowage requirements are required.
Section 176.905
    Section 176.905 prescribes specific requirements for motor vehicles 
or mechanical equipment powered by internal combustion engines that are 
offered for transportation and transported by vessel. For consistency 
with Amendment 35-10 of the IMDG Code, PHMSA is removing the signage 
requirement for such articles in paragraph (a)(5) and the ignition key 
removal provisions from paragraph (a)(6). Additionally, we are revising 
this section to account for modern designs of vehicles and equipment 
that are powered by engines other than internal combustion engines 
(e.g., electric engines powered by a fuel cell, hybrid vehicles). We 
are revising this section to include language applicable to address 
these new designs. We did not propose these changes in the August 24, 
2010 NPRM, but we do not believe including language to account for new 
designs imposes new restrictions or any greater burdens than currently 
in the regulations.

Part 178

Section 178.71
    Section 178.71 establishes the specifications for UN pressure 
receptacles. In this final rule, PHMSA is adopting the regulatory 
relief proposed in Docket HM-218F (75 FR 60017, 75 FR 60017) by 
revising the requirements in paragraph (c)(1) to allow the use of a 
proof pressure test in addition to the volumetric expansion test. The 
ISO 7866 and 9809 standards permit either the proof pressure test or 
volumetric expansion test to be used. The volumetric expansion test 
measures the cylinder's elastic expansion and assures the cylinder 
received a proper heat treatment. However, the ISO standards also 
require each cylinder be subjected to a hardness test and a 
comprehensive shear wave ultrasonic examination (UE). PHMSA believes 
the combination of the proof pressure test, hardness test, and UE 
should provide adequate assurance that each cylinder received a proper 
heat treatment. This limitation (i.e., volumetric expansion test only) 
is also removed from the test pressure marking requirement in the 
redesignated paragraph (p)(6).
    In this final rule, PHMSA is also amending the cylinder bundle 
marking requirements in Sec.  178.71(e) by adding a new paragraph 
(e)(8) specifying that pressure vessel markings only apply to the 
pressure vessel itself and not to the assembly structure of the bundle. 
Additionally, we are adding new paragraphs (f) and (m) that establish 
the design and construction requirements for UN metal hydride storage 
systems and refillable welded cylinders, respectively. To accomplish 
this, we are redesignating paragraphs (m) through (r) as paragraphs (n) 
through (s), and revising paragraphs (q) and (s) accordingly to correct 
paragraph references. Further, we are adding three ISO standards to the 
IBR table in Sec.  171.7 of the HMR for UN refillable welded cylinders 
(ISO 4706, 18172-1 and 20703). Lastly, we are requiring that 
transportable metal hydride storage systems (see Sec.  173.311) be 
designed, constructed, initially inspected and tested in accordance 
with ISO 16111:2008, ``Transportable gas storage devices--Hydrogen 
absorbed in reversible metal hydride,'' as authorized under Sec.  
178.71(m).
Section 178.275
    Section 178.275 prescribes requirements for UN portable tanks 
intended for transportation of liquid and solid hazardous materials. 
Section 178.275(h) prohibits the use of fusible elements on portable 
tanks with a test pressure which exceeds 2.65 bar (265 kPa). In Sec.  
172.102(c)(8), we are adding a new portable tank special provision TP36 
authorizing the use of fusible elements in the vapor space of portable 
tanks with a gauge test pressure that exceeds 265 kPa (38.4 psig/2.65 
bar) for certain organometallic substances. In this final rule, we are 
authorizing use of fusible elements based on a well-established history 
of safe transportation of these substances in portable tanks equipped 
with fusible elements capable of properly functioning at pressure of at 
least 1,000 kPa (145 psig/10 bar). Past experience of the use of 
fusible elements indicates reliability and a proper functioning even in 
the event of a release during loading or unloading. Additionally, for 
organometallic materials that are shipped in rigid portable tanks with 
a minimum test pressure of more than 265 kPa (38.4 psig/2.65 bar), the 
tanks are required to be equipped with a depressurizing system that 
releases the inside pressure to avoid rupturing the tank as a result of 
an inadvertent release or fire. Fusible elements are used by shippers 
as a secondary pressure relief device, in addition to a re-closing 
pressure relief device. Therefore, we are revising Sec.  178.275(h) to 
reference special provision TP36 authorizing the use of fusible 
elements in the vapor space of a portable tank used for the transport 
of certain organometallic materials.
Section 178.347-1
    Section 178.347-1 prescribes the general requirements for DOT 
Specification 407 cargo tank motor vehicles. Paragraph (d)(9) 
prescribes weld integrity, compliance and acceptance criteria for 
bulkheads.
    The exception in Sec.  178.347-1(d)(8) currently provides an 
unconditional exception from UW-12 for all joints. Section 178.347-
1(d)(9) applies a condition to one particular joint configuration in a 
head. In petition P-1333, TTMA requested that we adopt a weld joint 
efficiency of 0.85 for head seams in bulkheads on DOT 407 cargo tanks. 
Based on review of the TTMA petition and additional information that 
was provided, we proposed in the HM-213 NPRM (66 FR 63095, December 4, 
2001) that the strength of a weld seam in a bulkhead without 
radiographic examination of the weld must be 0.85 of the strength of 
the bulkhead. The welded seam must be a full penetration butt weld, no 
more than one seam may be used per bulkhead, and the welded seam must 
be completed before forming the dish radius and knuckle radius.
    TTMA commented on the proposal stating, ``[w]hile we agree with the

[[Page 3339]]

proposal to allow a provisional 85% weld joint efficiency for DOT 407 
heads with butt-welded seams, we would like to see the requirements of 
UW-12 of the ASME Code specifically exempted for this welded joint. 
Even though this section implies an exemption, the exemption is not 
specific. We suggest the following wording, ``[t]he strength of a weld 
seam in a bulkhead that has not been radiographically examined shall be 
0.85 of the strength of the bulkhead and be exempted from the 
requirements of UW-12 of the ASME Code under the following condition''.
    In the HM-213 final rule, we agreed with TTMA's comment and agreed 
to make the change though the change occurred in a corrections document 
(68 FR 52363, September 3, 2003). The final rule stated: ``[I]n its 
comments to the NPRM, TTMA agrees with the provisional 85% weld joint 
efficiency for DOT 407 heads with butt-welded seams. However, TTMA 
suggests that we include the requirements of Part UW-12 of the ASME 
Code to the list of excepted requirements in Sec.  178.347-1(d)(8). We 
agree with TTMA. In this final rule, we are adding Part UW-12 of the 
ASME Code to the list of excepted requirements.''
    In October 2004, we added an exception from the radiography/joint 
efficiency requirements of ASME VIII section UW-12 for DOT 407 cargo 
tanks with MAWP of 35 psig and less in Sec.  178.347-1(d)(8) and (9). 
The intent was to provide a conditional alternate means of determining 
a joint efficiency for certain head welds. Listing UW-12 in Sec.  
178.347-1(d)(8) instead of (9), however, results in an unconditional 
exception from UW-12 in all welds on these tanks. Therefore, because we 
believe the revision is appropriate, we are revising Sec.  178.347-
1(d)(9), as proposed, by adding a new subparagraph (i) and renumbering 
the section accordingly.
Section 178.603
    Section 178.603 prescribes the drop test requirements for non-bulk 
packagings in the HMR. In this final rule, PHMSA is revising paragraph 
(f)(4) to amend the criteria for passing the tests. The HMR require 
only that there is no leakage of filling substance from the inner 
packaging. In this final rule, we are also requiring that inner 
receptacles, inner packagings and articles remain completely within the 
outer package when drop tested.
Section 178.703
    Section 178.703 prescribes the marking requirements for IBCs. PHMSA 
is aligning paragraph (a)(1)(viii) with the UN Model Regulations by 
requiring the gross mass, in kilograms, to be marked on all IBC types. 
The HMR require a net mass to be marked on flexible IBCs which is 
inconsistent with international standards. PHMSA inadvertently did not 
revise the HMR under a previous harmonization rulemaking when the 
international standards were amended to specify that a maximum 
permissible gross mass be marked on all IBC types.
Section 178.955
    Section 178.955 establishes definitions used with regard to subpart 
Q of part 178, which prescribes the design and testing criteria for 
Large Packagings. PHMSA is adding the following two new definitions, 
``Remanufactured Large Packaging'' and ``Reused Large Packaging,'' in 
new paragraphs (c)(6) and (c)(7), respectively. A ``remanufactured'' 
large packaging is defined as a metal or rigid plastic large packaging 
that is produced as a UN type from a non-UN type or is converted from 
one UN design type to another UN design type. Remanufactured large 
packagings are subject to the same HMR requirements that apply to a new 
large packaging. A ``reused'' large packaging is defined as a large 
packaging to be refilled that has been examined and found free of 
defects affecting the ability to withstand the performance tests. The 
term includes those that are refilled with the same or similar 
compatible contents and are transported within distribution chains 
controlled by the consignor of the product.

Part 180

Section 180.207
    Section 180.207 prescribes the requirements for the requalification 
of UN pressure receptacles. In this final rule, PHMSA is requiring that 
metal hydride storage systems be requalified every five years in 
accordance with ISO 16111:2008 and that the records of that 
requalification be retained in accordance with Sec.  180.215 of the 
HMR.
Section 180.350
    Section 180.350 prescribes applicability and defines certain terms 
regarding the qualification and maintenance of IBCs. PHMSA is revising 
paragraph (b) to indicate that the replacement of the inner receptacle 
of a composite IBC with one from the original manufacturer is 
considered a repair. This revision is consistent with the recent change 
in the definition of ``repair'' in the UN Model Regulations.

V. Regulatory Analyses and Notices

A. Statutory/legal Authority for This Rulemaking

    This final rule is published under the following statutory 
authorities:
    1. 49 U.S.C. 5103(b) 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 amends regulations to maintain alignment with 
international standards by incorporating various amendments, including 
changes to proper shipping names, hazard classes, packing groups, 
special provisions, packaging authorizations, air transport quantity 
limitations and vessel stowage requirements. To this end, as discussed 
in detail above, the final rule amends the HMR to more fully align them 
with the biennial updates of the UN Model Regulations, the IMDG Code 
and the ICAO TI.
    Harmonization serves to facilitate international commerce. At the 
same time, harmonization promotes the safety of people, property, and 
the environment by reducing the potential for confusion and 
misunderstanding that could result if shippers and transporters were 
required to comply with two or more conflicting sets of regulatory 
requirements. While the intent of this rulemaking is to align the HMR 
with international standards, we review and consider each amendment on 
its own merit based on its overall impact on transportation safety and 
the economic implications associated with its adoption into the HMR. 
Our goal is to harmonize without sacrificing the current HMR level of 
safety and without imposing undue burdens on the regulated public. 
Thus, as explained in the corresponding sections above, we are not 
harmonizing with certain specific provisions of the UN Model 
Regulations, the IMDG Code, and the ICAO TI. Moreover, we are 
maintaining a number of current exceptions for domestic transportation 
that should minimize the compliance burden on the regulated community.
    2. 49 U.S.C. 5120(b) authorizes the Secretary of Transportation to 
ensure that, to the extent practicable, regulations governing the 
transportation of hazardous materials in commerce are consistent with 
standards adopted by international authorities. This rule amends the 
HMR to maintain alignment with international standards by incorporating 
various amendments to facilitate the transport of hazardous material in 
international commerce. To this end, as discussed in detail above,

[[Page 3340]]

PHMSA incorporates changes into the HMR based on the sixteenth revised 
edition of the UN Model Regulations and the 2011-2012 ICAO Technical 
Instructions, which become effective January 1, 2011, and Amendment 35-
10 to the IMDG Code which becomes effective January 1, 2012. The 
continually increasing amount of hazardous materials transported in 
international commerce warrants the harmonization of domestic and 
international requirements to the greatest extent possible.

B. Executive Order 12866 and DOT Regulatory Policies and Procedures

    This final rule is not considered a significant regulatory action 
under section 3(f) of Executive Order 12866 and, therefore, was not 
reviewed by the Office of Management and Budget. The final rule is not 
considered a significant rule under the Regulatory Policies and 
Procedures of the Department of Transportation (44 FR 11034). This 
final rule applies to offerors and carriers of hazardous materials, 
such as chemical manufacturers, chemical users and suppliers, packaging 
manufacturers, distributors, radiopharmaceutical companies, and 
training companies. Benefits resulting from the adoption of the 
amendments in this final rule include enhanced transportation safety 
resulting from the consistency of domestic and international hazard 
communications and continued access to foreign markets by U.S. 
manufacturers of hazardous materials.
    The majority of amendments in this final rule should result in cost 
savings and ease the regulatory compliance burden for shippers engaged 
in domestic and international commerce, including trans-border 
shipments within North America.
    We authorize a one year transition period to allow for training of 
employees and to ease any burden on entities affected by the 
amendments. The total net increase in costs to businesses in 
implementing the final rule is considered to be minimal. Initial start-
up and inventory costs will result from these changes. However, the 
costs are offset by greater long term savings of conformance with one 
set of regulations and a one-year transition period. A regulatory 
evaluation is available for review in the public docket for this 
rulemaking.

C. Executive Order 13132

    This final rule has been analyzed in accordance with the principles 
and criteria contained in Executive Order 13132 (``Federalism''). This 
final rule preempts State, local and Indian Tribe requirements but does 
not propose any regulation that has substantial direct effects on the 
States, the relationship between the national government and the 
States, or the distribution of power and responsibilities among the 
various levels of government. Therefore, the consultation and funding 
requirements of Executive Order 13132 do not apply.
    The Federal hazardous material transportation law, 49 U.S.C. 5101-
5128, contains an express preemption provision (49 U.S.C. 5125(b)) that 
preempts State, local and Indian Tribe requirements on certain covered 
subjects, as follows:
    (1) The designation, description, and classification of hazardous 
material;
    (2) The packing, repacking, handling, labeling, marking, and 
placarding of hazardous material;
    (3) The preparation, execution, and use of shipping documents 
related to hazardous material and requirements related to the number, 
contents, and placement of those documents;
    (4) The written notification, recording, and reporting of the 
unintentional release in transportation of hazardous material; and
    (5) The design, manufacture, fabrication, inspection, marking, 
maintenance, recondition, repair, or testing of a packaging or 
container represented, marked, certified, or sold as qualified for use 
in transporting hazardous material in commerce.
    This final rule addresses covered subject items (1), (2), (3), (4) 
and (5) above and preempts State, local, and Indian Tribe requirements 
not meeting the ``substantively the same'' standard. This final rule is 
necessary to incorporate changes adopted in international standards, 
effective January 1, 2011. If the changes in this final rule are not 
adopted into the HMR, U.S. companies, including numerous small entities 
competing in foreign markets, would be at an economic disadvantage. 
These companies would be forced to comply with a dual system of 
regulations. The changes in this final rulemaking are intended to avoid 
this result. Federal hazardous materials transportation law provides at 
49 U.S.C. 5125(b)(2) that, if DOT issues a regulation concerning any of 
the covered subjects, DOT must determine and publish in the Federal 
Register the effective date of Federal preemption. The effective date 
of Federal preemption is 90 days from publication of the final rule in 
this matter.

D. Executive Order 13175

    This final rule was analyzed in accordance with the principles and 
criteria contained in Executive Order 13175 (``Consultation and 
Coordination with Indian Tribal Governments''). Because this final rule 
does not have Tribal implications, does not impose substantial direct 
compliance costs, and is required by statute, the funding and 
consultation requirements of Executive Order 13175 do not apply.

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 that a rule is not expected to have a 
significant impact on a substantial number of small entities. This 
final rule facilitates the transportation of hazardous materials in 
international commerce by providing consistency with international 
standards. This final rule applies to offerors and carriers of 
hazardous materials, some of whom are small entities, such as chemical 
manufacturers, users and suppliers, packaging manufacturers, 
distributors and training companies. As discussed above, under 
Executive Order 12866, the majority of amendments in this final rule 
should result in cost savings and ease the regulatory compliance burden 
for shippers engaged in domestic and international commerce, including 
trans-border shipments within North America.
    Many companies will realize economic benefits as a result of these 
amendments. Additionally, the changes effected by this final rule will 
relieve U.S. companies, including small entities competing in foreign 
markets, from the burden of complying with a dual system of 
regulations. Therefore, I certify that these amendments will not, if 
promulgated, 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

    PHMSA currently has approved information collections under Office 
of Management and Budget (OMB) Control Number 2137-0034, ``Hazardous 
Materials Shipping Papers and Emergency Response Information,'' with an 
expiration date of May 31, 2011, and OMB Control Number 2137-0557,

``Approvals for Hazardous Materials,'' with an expiration date of June 
30, 2011. This final rule may result in a decrease in the annual burden 
and costs of OMB Control Number 2137-0034 due to amendments to the 
exceptions for shipping paper requirements for limited quantities of 
Class 3, Division 4.1, Division 4.2, Division 4.3, Division 5.1, 
Division 5.2, Division 6.1, Class 8, and Class 9 materials for those 
limited quantities that are defined as consumer commodities. This final 
rule may result in an increase in the annual burden and costs of OMB 
Control Number 2137-0557 due to amendments to the classification 
criteria for eight Division 1.4 explosive articles to add the Type 6(d) 
test as prescribed in the fifth revised edition of the UN Manual of 
Tests and Criteria.
    Under the Paperwork Reduction Act of 1995, no person is required to 
respond to an information collection unless it has been approved by OMB 
and displays a valid OMB control number. Section 1320.8(d), Title 5, 
Code of Federal Regulations requires that PHMSA provide interested 
members of the public and affected agencies an opportunity to comment 
on information and recordkeeping requests.
    This final rule identifies revised information collection requests 
that PHMSA will submit to OMB for approval based on the requirements in 
this final rule. PHMSA has developed burden estimates to reflect 
changes in this final rule, and estimates the information collection 
and recordkeeping burden as proposed in this rule to be as follows:

------------------------------------------------------------------------
 
------------------------------------------------------------------------
OMB Control No.                                                2137-0034
------------------------------------------------------------------------
Annual Decrease in Number of Respondents..............        75,000,000
Annual Decrease in Annual Number of Responses.........        75,000,000
Annual Decrease in Annual Burden Hours................         1,875,000
Annual Decrease in Annual Burden Costs................     $1,875,000.00
------------------------------------------------------------------------
OMB Control No.                                                2137-0557
------------------------------------------------------------------------
Annual Increase in Number of Respondents..............               465
Annual Increase in Annual Number of Responses.........               465
Annual Increase in Annual Burden Hours................             2,325
Annual Increase in Annual Burden Costs................           $58,125
------------------------------------------------------------------------

    PHMSA will submit the revised information collection and 
recordkeeping requirements to OMB for approval.

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 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 
$141.3 million or more, adjusted for inflation, to either State, local 
or Tribal governments, in the aggregate, or to the private sector in 
any one year, 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 that Federal agencies analyze proposed actions to determine 
whether the action will have a significant impact on the human 
environment. The Council on Environmental Quality (CEQ) regulations 
order 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. 40 CFR 1508.9(b).
1. Purpose and Need
    PHMSA proposed to amend the Hazardous Materials Regulations to 
maintain alignment with international standards by incorporating 
various amendments, including changes to proper shipping names, hazard 
classes, packing groups, special provisions, packaging authorizations, 
air transport quantity limitations, and vessel stowage requirements. 
These revisions are necessary to harmonize the Hazardous Materials 
Regulations with recent changes to the International Maritime Dangerous 
Goods Code, the International Civil Aviation Organization's Technical 
Instructions for the Transport of Dangerous Goods by Air, and the 
United Nations Recommendations on the Transport of Dangerous Goods. The 
amendments are intended to enhance the safety of international 
hazardous materials transportation through better understanding of the 
regulations, an increased level of industry compliance, the smooth flow 
of hazardous materials from their points of origin to their points of 
destination, and effective emergency response in the event of a 
hazardous materials incident.
    The HMR regulate materials that meet the definition of a marine 
pollutant in all modes of transportation. The intended effect is to 
increase the level of safety associated with the transportation of 
substances hazardous to the marine environment by way of improved 
communication of their presence in transportation and establishing 
appropriate requirements for their packaging. The HMR uses a list-based 
system designed to help shippers determine if a material meets the 
definition of a marine pollutant. Recently, the IMO adopted a criteria 
based system for identification of materials hazardous to the marine 
environment based on the Globally Harmonized System of Classification 
and Labeling of Chemicals (GHS).
2. Alternatives
    In developing this proposed rule, we considered three alternatives:
    (1) Do nothing.
    (2) Adopt the international standards in their entirety.
    (3) Adopt most of the international standards, with certain 
modifications based on safety or economic considerations.
    Alternative 1: Because our goal is to facilitate uniformity, 
compliance, commerce and safety in the transportation of hazardous 
materials, we rejected this alternative.
    Alternative 2: By adopting the international standards in their 
entirety,

[[Page 3342]]

PHMSA could potentially adopt provisions that, in our view, do not 
provide an adequate safety level. Further, because we provide for 
domestic exceptions and extended compliance periods to minimize the 
potential economic impact of any revisions on the regulated community, 
this alternative was also rejected.
    Alternative 3: Consistency between U.S. and international 
regulations helps to assure the safety of international hazardous 
materials transportation through better understanding of the 
regulations, an increased level of industry compliance, the smooth flow 
of hazardous materials from their points of origin to their points of 
destination, and effective emergency response in the event of a 
hazardous materials incident. Under Alternative 3, we would harmonize 
the HMR with international standards to the extent consistent with U.S. 
safety and economic goals.
    Alternative 3 is the only alternative that addresses, in all 
respects, the purpose of this regulatory action, which is to facilitate 
the safe and efficient transportation of hazardous materials in 
international commerce. These actions will provide the greatest 
possible harmonization with international requirements without posing 
an undue increased cost burden on industry. For these reasons, 
Alternative 3 is our recommended alternative.
3. Analysis of Environmental Impacts
    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, or loading, unloading, or handling problems. The ecosystems 
that could be affected by a release include air, water, soil, and 
ecological resources (e.g., wildlife habitats). The adverse 
environmental impacts associated with releases of most hazardous 
materials are short-term impacts that can be greatly reduced or 
eliminated through prompt clean-up of the accident scene. Most 
hazardous materials are not transported in quantities sufficient to 
cause significant, long-term environmental damage if they are released.
    The hazardous material regulatory system is a risk-management 
system that is prevention-oriented and focused on identifying hazards 
and reducing the probability and quantity of a hazardous material 
release. Amending the HMR to maintain alignment with international 
standards enhances the safe transportation of hazardous materials in 
domestic and international commerce. When considering the adoption of 
international standards under the HMR, we review and consider each 
amendment on its own merit and assess its impact on transportation 
safety and the environment. Based on the lack of public comment on the 
issue, it is our conclusion that the amendments adopted in this final 
rule will have no adverse affect on the environment.
4. Consultations and Public Comment
    On June 20, 2007, November 27, 2007, June 18, 2008, and November 
19, 2008, PHMSA hosted public meetings with public and private 
stakeholders to discuss draft U.S. positions on the United Nation's 
Sub-Committee of Experts on the Transport of Dangerous Goods (UNSCOE) 
proposals for the sixteenth revised edition of the UN Recommendations 
on the Transport of Dangerous Goods Model Regulations. In addition, 
PHMSA and the U.S. Coast Guard hosted a public meeting on September 17, 
2008, and hosted a second meeting on September 10, 2009, to discuss 
amendments to the IMDG Code. A public meeting was held on September 29, 
2009 to discuss amendments to the ICAO Technical Instructions. During 
these public meetings, U.S. positions on proposed amendments to the UN 
Recommendations were considered and discussed. Positions were 
established based on input received during these meetings in 
conjunction with internal review, including thorough technical review.
    We have identified a number of immediate and long-term actions that 
participants in the international community are taking or will take to 
enhance the safe transportation of hazardous materials. Through this 
integrated and cooperative approach, we believe we can be most 
successful in reducing incidents, enhancing safety, and protecting the 
public.

J. Privacy Act

    Anyone is able to search the electronic form of any written 
communications and comments received into any of our dockets by the 
name of the individual submitting the document (or signing the 
document, if submitted on behalf of an association, business, labor 
union, etc.). You may review DOT's complete Privacy Act Statement in 
the Federal Register published on April 11, 2000 (65 FR 19477) or you

K. International Trade Analysis

    The Trade Agreements Act of 1979 (Pub. L. 96-39), as amended by the 
Uruguay Round Agreements Act (Pub. L. 103-465), prohibits Federal 
agencies from establishing any standards or engaging in related 
activities that create unnecessary obstacles to the foreign commerce of 
the United States. For purposes of these requirements, Federal agencies 
may participate in the establishment of international standards, so 
long as the standards have a legitimate domestic objective, such as 
providing for safety, and do not operate to exclude imports that meet 
this objective. The statute also requires consideration of 
international standards and, where appropriate, that they be the basis 
for U.S. standards. PHMSA participates in the establishment of 
international standards to protect the safety of the American public, 
and we have assessed the effects of the proposed rule to ensure that it 
does not exclude imports that meet this objective. Accordingly, this 
rulemaking is consistent with PHMSA's obligations under the Trade 
Agreement Act, as amended.

3. In Sec.  171.8, the definitions for ``Metal hydride storage system'' 
and ``Open cryogenic receptacle'' are added and the definitions for 
``Oxidizing gas'' and ``UN Recommendations'' are revised to read as 
follows:

Sec.  171.8  Definitions and abbreviations.

* * * * *
    Metal hydride storage system means a single complete hydrogen 
storage system that includes a receptacle, metal hydride, pressure 
relief device, shut-off valve, service equipment and internal 
components used for the transportation of hydrogen only.
* * * * *
    Open cryogenic receptacle means a transportable thermally insulated 
receptacle for refrigerated liquefied gases maintained at atmospheric 
pressure by continuous venting of the refrigerated gas.
* * * * *
    Oxidizing gas means a gas that may, generally by providing oxygen, 
cause or contribute to the combustion of other material more than air 
does. Specifically, this means a pure gas or gas mixture with an 
oxidizing power greater than 23.5% as determined by a method specified 
in ISO 10156: or 10156-2: (IBR, see Sec.  171.7 of this subchapter) 
(see also Sec.  173.115(k)).
* * * * *
    U.N. Recommendations means the U.N. Recommendations on the 
Transport of Dangerous Goods, Model Regulations (IBR, see Sec.  171.7 
of this subchapter).

Sec.  172.101  Purpose and use of hazardous materials table.

* * * * *

[[Page 3346]]

    (c) * * *
    (10) * * *
    (i) A mixture or solution not identified specifically by name, 
comprised of a single predominant hazardous material identified in the 
Table by technical name and one or more hazardous and/or non-hazardous 
material, must be described using the proper shipping name of the 
hazardous material and the qualifying word ``mixture'' or ``solution'', 
as appropriate, unless--
    (A) Except as provided in Sec.  172.101(i)(4) the packaging 
specified in Column 8 is inappropriate to the physical state of the 
material;
    (B) The shipping description indicates that the proper shipping 
name applies only to the pure or technically pure hazardous material;
    (C) The hazard class, packing group, or subsidiary hazard of the 
mixture or solution is different from that specified for the entry;
    (D) There is a significant change in the measures to be taken in 
emergencies;
    (E) The material is identified by special provision in Column 7 of 
the Sec.  172.101 Table as a material poisonous by inhalation; however, 
it no longer meets the definition of poisonous by inhalation or it 
falls within a different hazard zone than that specified in the special 
provision; or
    (F) The material can be appropriately described by a shipping name 
that describes its intended application, such as ``Coating solution'', 
``Extracts, flavoring'' or ``Compound, cleaning liquid.''
* * * * *
    (e) * * * Those preceded by the letters ``ID'' are associated with 
proper shipping names recognized by the ICAO Technical Instructions 
(IBR, see Sec.  171.7 of this subchapter).

    (1) * * *

Code/Special Provisions

* * * * *
    15 This entry applies to ``Chemical kits'' and ``First aid kits'' 
containing one or more compatible items of hazardous materials in 
boxes, cases, etc. that, for example, are used for medical, analytical, 
diagnostic, testing, or repair purposes. Kits that are carried on board 
transport vehicles for first aid or operating purposes are not subject 
to the requirements of this subchapter.
* * * * *
    40 Polyester resin kits consist of two components: A base material 
(Class 3, Packing Group II or III) and an activator (organic peroxide), 
each separately packed in an inner packaging. The organic peroxide must 
be type D, E, or F, not requiring temperature control. The components 
may be placed in the same outer packaging provided they will not 
interact dangerously in the event of leakage. The Packing Group 
assigned will be II or III, according to the classification criteria 
for Class 3, applied to the base material. Additionally, unless 
otherwise excepted in this subchapter, polyester resin kits must be 
packaged in specification combination packagings based on the 
performance level of the base material contained within the kit.
* * * * *
    78 This entry may not be used to describe compressed air which 
contains more than 23.5 percent oxygen. Compressed air containing 
greater than 23.5 percent oxygen must be shipped using the description 
``Compressed gas, oxidizing, n.o.s., UN3156.''
* * * * *
    110 Fire extinguishers transported under UN1044 and oxygen 
cylinders transported for emergency use under UN1072 may include 
installed actuating cartridges (cartridges, power device of Division 
1.4C or 1.4S), without changing the classification of Division 2.2, 
provided the aggregate quantity of deflagrating (propellant) explosives 
does not exceed 3.2 grams per cylinder. Oxygen cylinders with installed 
actuating cartridges as prepared for transportation must have an 
effective means of preventing inadvertent activation.
* * * * *
    130 ``Batteries, dry, sealed, n.o.s.,'' commonly referred to as dry 
batteries, are hermetically sealed and generally utilize metals (other 
than lead) and/or carbon as electrodes. These batteries are typically 
used for portable power applications. The rechargeable (and some non-
rechargeable) types have gelled alkaline electrolytes (rather than 
acidic) making it difficult for them to generate hydrogen or oxygen 
when overcharged and therefore, differentiating them from non-spillable 
batteries. Dry batteries specifically covered by another entry in the 
Sec.  172.101 Table must be transported in accordance with the 
requirements applicable to that entry. For example, nickel-metal 
hydride batteries transported by vessel in certain quantities are 
covered by another entry (see Batteries, nickel-metal hydride, UN3496). 
Dry batteries not specifically covered by another entry in the Sec.  
172.101 Table are covered by this entry (i.e., Batteries, dry, sealed, 
n.o.s.) and are not subject to requirements of this subchapter except 
for the following:
    (a) Incident reporting. For transportation by aircraft, a telephone 
report in accordance with Sec.  171.15(a) is required if a fire, 
violent rupture, explosion or dangerous evolution of heat (i.e., an 
amount of heat sufficient to be dangerous to packaging or personal 
safety to include charring of packaging, melting of packaging, 
scorching of packaging, or other evidence) occurs as a direct result of 
a dry battery. For all modes of transportation, a written report 
submitted, retained, and updated in accordance with Sec.  171.16 is 
required if a fire, violent rupture, explosion or dangerous evolution 
of heat occurs as a direct result of a dry battery or battery-powered 
device.
    (b) Preparation for transport. Batteries and battery-powered 
device(s) containing batteries must be prepared and packaged for 
transport in a manner to prevent:
    (1) A dangerous evolution of heat;
    (2) Short circuits, including but not limited to the following 
methods:
    (i) Packaging each battery or each battery-powered device when 
practicable, in fully enclosed inner packagings made of non-conductive 
material;
    (ii) Separating or packaging batteries in a manner to prevent 
contact with other batteries, devices or conductive materials (e.g., 
metal) in the packagings; or
    (iii) Ensuring exposed terminals or connectors are protected with 
non-conductive caps, non-conductive tape, or by other appropriate 
means; and
    (3) Damage to terminals. If not impact resistant, the outer 
packaging should not be used as the sole means of protecting the 
battery terminals from damage or short circuiting. Batteries must be 
securely cushioned and packed to prevent shifting which could loosen 
terminal caps or reorient the terminals to produce short circuits. 
Batteries contained in devices must be securely installed. Terminal 
protection methods include but are not limited to the following:
    (i) Securely attaching covers of sufficient strength to protect the 
terminals;
    (ii) Packaging the battery in a rigid plastic packaging; or
    (iii) Constructing the battery with terminals that are recessed or 
otherwise protected so that the terminals will not be subjected to 
damage if the package is dropped.
    (c) Additional air transport requirements. For a battery whose 
voltage (electrical potential) exceeds 9 volts--
    (1) When contained in a device, the device must be packaged in a 
manner that prevents unintentional activation or must have an 
independent means of preventing unintentional activation (e.g., 
packaging restricts access to activation switch, switch caps or locks, 
recessed switches, trigger locks, temperature sensitive circuit 
breakers, etc.); and
    (2) An indication of compliance with this special provision must be 
provided by marking each package with the words ``not restricted'' or 
by including the words ``not restricted'' on a transport document such 
as an air waybill accompanying the shipment.
    (d) Used or spent battery exception. Used or spent dry batteries of 
both non-rechargeable and rechargeable designs, with a marked rating up 
to 9-volt that are combined in the same package and

[[Page 3363]]

transported by highway or rail for recycling, reconditioning, or 
disposal are not subject to this special provision or any other 
requirement of the HMR. Note that batteries utilizing different 
chemistries (i.e., those battery chemistries specifically covered by 
another entry in the Sec.  172.101 Table) as well as dry batteries with 
a marked rating greater than 9-volt may not be combined with used or 
spent batteries in the same package. Note also that this exception does 
not apply to batteries that have been reconditioned for reuse.
* * * * *
    134 This entry only applies to vehicles, machinery and equipment 
powered by wet batteries, sodium batteries, or lithium batteries that 
are transported with these batteries installed. Examples of such items 
are electrically-powered cars, lawn mowers, wheelchairs, and other 
mobility aids. Self-propelled vehicles or equipment that also contain 
an internal combustion engine must be consigned under the entry 
``Engine, internal combustion, flammable gas powered'' or ``Engine, 
internal combustion, flammable liquid powered'' or ``Vehicle, flammable 
gas powered'' or ``Vehicle, flammable liquid powered,'' as appropriate. 
These entries include hybrid electric vehicles powered by both an 
internal combustion engine and batteries. Additionally, self-propelled 
vehicles or equipment that contain a fuel cell engine must be consigned 
under the entries ``Engine, fuel cell, flammable gas powered'' or 
``Engine, fuel cell, flammable liquid powered'' or ``Vehicle, fuel 
cell, flammable gas powered'' or ``Vehicle, fuel cell, flammable liquid 
powered,'' as appropriate. These entries include hybrid electric 
vehicles powered by a fuel cell engine, an internal combustion engine, 
and batteries.
    135 Internal combustion engines installed in a vehicle must be 
consigned under the entries ``Vehicle, flammable gas powered'' or 
``Vehicle, flammable liquid powered,'' as appropriate. These entries 
include hybrid electric vehicles powered by both an internal combustion 
engine and wet, sodium or lithium batteries installed. If a fuel cell 
engine is installed in a vehicle, the vehicle must be consigned using 
the entries ``Vehicle, fuel cell, flammable gas powered'' or ``Vehicle, 
fuel cell, flammable liquid powered,'' as appropriate. These entries 
include hybrid electric vehicles powered by a fuel cell, an internal 
combustion engine, and wet, sodium or lithium batteries installed.
* * * * *
    149 Except for transportation by aircraft, when transported as a 
limited quantity or a consumer commodity, the maximum net capacity 
specified in Sec.  173.150(b)(2) of this subchapter for inner 
packagings may be increased to 5 L (1.3 gallons).
* * * * *
    167 These storage systems must always be considered as containing 
hydrogen. A metal hydride storage system installed in or intended to be 
installed in a vehicle or equipment or in vehicle or equipment 
components must be approved for transport by the Associate 
Administrator. A copy of the approval must accompany each shipment.
* * * * *
    198 Nitrocellulose solutions containing not more than 20% 
nitrocellulose may be transported as paint, perfumery products, or 
printing ink, as applicable, provided the nitrocellulose contains no 
more 12.6% nitrogen (by dry mass). See UN1210, UN1263, UN1266, UN3066, 
UN3469, and UN3470.

    340 This entry applies only to the vessel transportation of nickel-
metal hydride batteries as cargo. Nickel-metal hydride button cells or 
nickel-metal hydride cells or batteries packed with or contained in 
battery-powered devices transported by vessel are not subject to the 
requirements of this special provision. See ``Batteries, dry, sealed, 
n.o.s.'' in the Sec.  172.101 Hazardous Materials Table (HMT) of this 
part for transportation requirements for nickel-metal hydride batteries 
transported by other modes and for nickel-metal hydride button cells or 
nickel-metal hydride cells or batteries packed with or contained in 
battery-powered devices transported by vessel. Nickel-metal hydride 
batteries subject to this special provision are subject only to the 
following requirements: (1) The batteries must be prepared and packaged 
for transport in a manner to prevent a dangerous evolution of heat, 
short circuits, and damage to terminals; and are subject to the 
incident reporting in accordance with Sec.  171.16 of this subchapter 
if a fire, violent rupture, explosion or dangerous evolution of heat 
(i.e., an amount of heat sufficient to be dangerous to packaging or 
personal safety to include charring of packaging, melting of packaging, 
scorching of packaging, or other evidence) occurs as a direct result of 
a nickel metal hydride battery; and (2) when loaded in a cargo 
transport unit in a total quantity of 100 kg gross mass or more, the

only for use in sterilization devices, when containing less than 30 mL 
of ethylene oxide per inner packaging with not more than 300 mL per 
outer packaging, may be transported in accordance with Sec.  173.4a of 
this subchapter, irrespective of the restriction of Sec.  173.4a(b) 
provided that:
    a. After filling, each glass inner packaging must be determined to 
be leak-tight by placing the glass inner packaging in a hot water bath 
at a temperature and for a period of time sufficient to ensure that an 
internal pressure equal to the vapor pressure of ethylene oxide at 55 
[deg]C is achieved. Any glass inner packaging showing evidence of 
leakage, distortion or other defect under this test must not be 
transported under the terms of this special provision;
    b. In addition to the packaging required in Sec.  173.4a, each 
glass inner packaging must be placed in a sealed plastic bag compatible 
with ethylene oxide and capable of containing the contents in the event 
of breakage or leakage of the glass inner packaging; and
    c. Each glass inner packaging is protected by a means of preventing 
puncture of the plastic bag (e.g., sleeves or cushioning) in the event 
of damage to the packaging (e.g., by crushing).

the use of an intermediate and leakproof form of containment, such as a 
liner, is required.
    (v) Packages must be capable of passing a 1.2 m drop test on to a 
rigid, non-resilient, flat and horizontal surface, in the position most 
likely to cause damage. The criteria for passing the test is that the 
outer packaging must not exhibit any damage affecting safety in 
transport and there must be no leakage from the inner packagings.
    (vi) Each package must be capable of withstanding, without breakage 
or leakage of any inner packaging, a force applied to the top surface 
for a duration of 24 hours equivalent to the total weight of identical 
packages if stacked to a height of 3 m (including the test sample).

72. Section 178.71 is revised to read as follows:

Sec.  178.71  Specifications for UN pressure receptacles.

    (a) General. Each UN pressure receptacle must meet the requirements 
of this section. Requirements for approval, qualification, maintenance, 
and testing are contained in Sec.  178.70, and subpart C of part 180 of 
this subchapter.
    (b) Definitions. The following definitions apply for the purposes 
of design and construction of UN pressure receptacles under this 
subpart:
    Alternative arrangement means an approval granted by the Associate 
Administrator for a MEGC that has been designed, constructed or tested 
to the technical requirements or testing methods other than those 
specified for UN pressure receptacles in part 178 or part 180 of this 
subchapter.
    Bundle of cylinders. See Sec.  171.8 of this subchapter.
    Design type means a pressure receptacle design as specified by a 
particular pressure receptacle standard.
    Design type approval means an overall approval of the 
manufacturer's quality system and design type of each pressure 
receptacle to be produced within the manufacturer's facility.
    UN tube. See Sec.  171.8 of this subchapter.
    (c) General design and construction. UN pressure receptacles and 
their closures must be designed, manufactured, tested and equipped in 
accordance with the requirements contained in this section. The ISO 
standard requirements applicable to UN pressure receptacles may be 
varied only if approved in writing by the Associate Administrator.
    (d) Service equipment. (1) Except for pressure relief devices, UN 
pressure receptacle equipment, including valves, piping, fittings, and 
other equipment subjected to pressure must be designed and constructed 
to withstand at least 1.5 times the test pressure of the pressure 
receptacle.
    (2) Service equipment must be configured or designed to prevent 
damage that could result in the release of the pressure receptacle 
contents during normal conditions of handling and transport. Manifold 
piping leading to shut-off valves must be sufficiently flexible to 
protect the valves and the piping from shearing or releasing the 
pressure receptacle contents. The filling and discharge valves and any 
protective caps must be secured against unintended opening. The valves 
must conform to ISO 10297 (IBR, see Sec.  171.7 of this subchapter) and 
be protected as specified in Sec.  173.301b(f) of this subchapter.
    (3) UN pressure receptacles that cannot be handled manually or 
rolled, must be equipped with devices (e.g., skids, rings, straps) 
ensuring that they can be safely handled by mechanical means and so 
arranged as not to impair the strength of, nor cause undue stresses, in 
the pressure receptacle.
    (4) Pressure receptacles filled by volume must be equipped with a 
level indicator.
    (e) Bundles of cylinders. UN pressure receptacles assembled in 
bundles must be structurally supported and held together as a unit and 
secured in a manner that prevents movement in relation to the 
structural assembly and movement that would result in the concentration 
of harmful local stresses. The frame design must ensure stability under 
normal operating conditions.
    (1) The frame must securely retain all the components of the bundle 
and must protect them from damage during conditions normally incident 
to transportation. The method of cylinder restraint must prevent any 
vertical or horizontal movement or rotation of the cylinder that could 
cause undue strain on the manifold. The total assembly must be able to 
withstand rough handling, including being dropped or overturned.
    (2) The frame must include features designed for the handling and 
transportation of the bundle. The lifting rings must be designed to 
withstand a design load of 2 times the maximum gross weight. Bundles 
with more than one lifting ring must be designed such that a minimum 
sling angle of 45 degrees to the horizontal can be achieved during 
lifting using the lifting rings. If four lifting rings are used, their 
design must be strong enough to allow the bundle to be lifted by two 
rings. Where two or four lifting rings are used, diametrically opposite 
lifting rings must be aligned with each other to allow for correct 
lifting using shackle pins. If the bundle is filled with forklift 
pockets, it must contain two forklift pockets on each side from which 
it is to be lifted. The forklift pockets must be positioned

[[Page 3386]]

symmetrically consistent with the bundle center of gravity.
    (3) The frame structural members must be designed for a vertical 
load of 2 times the maximum gross weight of the bundle. Design stress 
levels may not exceed 0.9 times the yield strength of the material.
    (4) The frame must not contain any protrusions from the exterior 
frame structure that could cause a hazardous condition.
    (5) The frame design must prevent collection of water or other 
debris that would increase the tare weight of bundles filled by weight.
    (6) The floor of the bundle frame must not buckle during normal 
operating conditions and must allow for the drainage of water and 
debris from around the base of the cylinders.
    (7) If the frame design includes movable doors or covers, they must 
be capable of being secured with latches or other means that will not 
become dislodged by operational impact loads. Valves that need to be 
operated in normal service or in an emergency must be accessible.
    (8) For bundles of cylinders, pressure receptacle marking 
requirements only apply to the individual cylinders of a bundle and not 
to any assembly structure.
    (f) Design and construction requirements for UN refillable welded 
cylinders. In addition to the general requirements of this section, UN 
refillable welded cylinders must conform to the following ISO

    (r) Other markings. Other markings are allowed in areas other than 
the side wall, provided they are made in low stress areas and are not 
of a size and depth that will create harmful stress concentrations. 
Such marks must not conflict with required marks.
    (s) Marking of UN non-refillable pressure receptacles. Unless 
otherwise specified in this paragraph, each UN non-refillable pressure 
receptacle must be clearly and legibly marked as prescribed in 
paragraph (p) of this section. In addition, permanent stenciling is 
authorized. Except when stenciled, the marks must be on the shoulder, 
top end or neck of the pressure receptacle or on a permanently affixed 
component of the pressure receptacle (e.g., a welded collar).
    (1) The marking requirements and sequence listed in paragraphs 
(p)(1) through (19) of this section are required, except the markings 
in paragraphs (p)(8), (9), (12) and (18) are not applicable. The 
required serial number marking in paragraph (p)(14) may be replaced by 
the batch number.
    (2) Each receptacle must be marked with the words ``DO NOT REFILL'' 
in letters of at least 5 mm in height.
    (3) A non-refillable pressure receptacle, because of its size, may 
substitute the marking required by this paragraph with a label. 
Reduction in marking size is authorized only as prescribed in ISO 7225, 
Gas cylinders--Precautionary labels. (IBR, see Sec.  171.7 of this 
subchapter).
    (4) Each non-refillable pressure receptacle must also be legibly 
marked by stenciling the following statement: ``Federal law forbids 
transportation if refilled-penalty up to $500,000 fine and 5 years in 
imprisonment (49 U.S.C. 5124).''
    (5) No person may mark a non-refillable pressure receptacle as 
meeting the requirements of this section unless it was manufactured in 
conformance with this section.

    (h) Fusible elements. Fusible elements must operate at a 
temperature between 110 [deg]C (230 [deg]F) and 149 [deg]C (300.2 
[deg]F), provided that the pressure in the shell at the fusing 
temperature will not exceed the test pressure. They must be placed at 
the top of the shell with their inlets in the vapor space and in no 
case may they be shielded from external heat. Fusible elements must not 
be utilized on portable tanks with a test pressure which exceeds 2.65 
bar (265.0 kPa); however, fusible elements are authorized on portable 
tanks for the transportation of certain organometallic materials in 
accordance with Sec.  172.102, special provision TP36 of this 
subchapter. Fusible elements used on portable tanks intended for the 
transport of elevated temperature hazardous materials must be designed 
to operate at a temperature higher than the maximum temperature that 
will be experienced during transport and must be designed to the 
satisfaction of the approval agency.

    (9) UW-12 in Section VIII of the ASME Code does not apply to a weld 
seam in a bulkhead that has not been radiographically examined, under 
the following conditions:
    (i) The strength of the weld seam is assumed to be 0.85 of the 
strength of the bulkhead.
    (ii) The welded seam must be a full penetration butt weld.
    (iii) No more than one seam may be used per bulkhead.
    (iv) The welded seam must be completed before forming the dish 
radius and knuckle radius.
    (v) Compliance test: Two test specimens of materials representative 
of those to be used in the manufacture of a cargo tank bulkhead must be 
tested to failure in tension. The test specimen must be of the same 
thickness and joined by the same welding procedure.

[[Page 3389]]

The test specimens may represent all the tanks that are made in the 
same facility within 6 months after the tests are completed. Before 
welding, the fit-up of the joints on the test specimens must represent 
production conditions that would result in the least joint strength. 
Evidence of joint fit-up and test results must be retained at the 
manufacturer's facility for at least 5 years.
    (vi) Acceptance criteria: The ratio of the actual tensile stress at 
failure to the actual tensile strength of the adjacent material of all 
samples of a test lot must be greater than 0.85.
