I. Background

    By notice of proposed rulemaking (NPRM) published August 31, 2006, 
the Pipeline and Hazardous Materials Safety Administration (PHMSA, we) 
published proposed revisions to the hazard communication, 
classification, and packaging requirements of the Hazardous Materials 
Regulations (HMR), 49 CFR parts 171-180, to align with updates and 
revisions to the United Nations Recommendations on the Transport of 
Dangerous Goods (UN Recommendations), the International Maritime 
Dangerous Goods (IMDG) Code and the International Civil Aviation 
Organization (ICAO) Technical Instructions for the Transport of 
Dangerous Goods by Air. The UN Recommendations are amended and updated 
biennially by the UN Committee of Experts on the Transport of Dangerous 
Goods and on the Globally Harmonized System of Classification and 
Labeling of Chemicals and serve as the basis for national, regional, 
and international modal regulations, including the IMDG Code, and the 
ICAO Technical Instructions.
    The harmonization of domestic and international standards becomes 
increasingly important as the volume of hazardous materials transported 
in international commerce grows. Harmonization facilitates 
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. By 
facilitating compliance, harmonization also tends to enhance safety for 
international movements, but only if the international standards 
themselves provide an appropriate level of safety. To that end, 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 consider each amendment on its own merit. Each amendment 
is considered 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 without imposing undue burdens 
on the regulated public.
    To maintain alignment of the HMR with international requirements, 
in this final rule, we are incorporating changes into the HMR based on 
the Fourteenth revised edition of the UN Recommendations and UN Manual 
of Tests and Criteria, Amendment 33 to the IMDG Code, and the 2007-2008 
ICAO Technical Instructions, which become effective January 1, 2007. We 
are also addressing petitions for rulemaking concerning harmonization 
with international standards and additional measures to facilitate 
international transportation.

2006. PHMSA received 28 comments in response to the proposed 
rulemaking. The following individuals, companies and organizations

    Commenters were supportive of PHMSA's efforts to harmonize the HMR 
with international standards. Many of the proposals in the NPRM are 
fully supported by commenters, while others received little or no 
comment; these amendments are adopted as proposed. Several comments 
were beyond the scope of this rulemaking and are not addressed in this 
final rule.
    In the NPRM, we requested comments on whether certain amendments 
should be tied to a sunset provision. We received six comments (GPS, 
IME, NTTC, AP&C, ATA, and NPCA) opposing the idea of a sunset 
provision. We agree with the commenters that for an international 
harmonization rulemaking, sunsetting some or all of the regulatory 
provisions is not appropriate. Therefore, we are not adopting a sunset 
provision for the amendments in this final rule. Other comments are 
discussed in the Section-by-Section Review.

II. Overview

A. Amendments Adopted in This Final Rule

    In this final rule, we are adopting the following amendments to the 
HMR:
     Adoption of a single shipping paper description sequence 
(identification number, proper shipping name, hazard class or division, 
packing group).
     Requirement to indicate the net quantity of hazardous 
material per package on the shipping paper if transportation is by 
aircraft.
     Incorporation by reference of the updated ICAO Technical 
Instructions, IMDG Code, and UN Recommendations.
     Amendments to the Hazardous Materials Table (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 vessels stowage provisions.
     Revision of the ORGANIC PEROXIDE label and placard.
     Revision of the classification criteria for PG III 
flammable liquids.
     Revision of the classification criteria and packing group 
assignments for Division 6.1 materials.
     Requirements for the transportation of fuel cells 
containing flammable liquid.
     Adoption of a one-packet limit for matches carried by 
airline passengers or crew members.

B. International Standards Not Being Adopted in This Final Rule

    This final rule makes changes to the HMR based on amendments to the 
Fourteenth revised edition of the UN Recommendations, Amendment 33 to 
the IMDG Code, and the 2007-2008 ICAO Technical Instructions, which 
become effective January 1, 2007. However, we are not adopting all of 
the amendments to those documents into the HMR. In many cases, 
amendments to the international regulations have not been adopted 
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. For example, we 
addressed requirements related to the transportation of infectious 
substances in a final rule published June 2, 2006, under Docket HM-226A 
(71 FR 32244). Similarly, we adopted amendments relating to the use of 
UN cylinders and pressure vessels in a final rule published June 12, 
2006, under Docket HM-220E (71 FR 33858).
    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 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:
     Environmentally hazardous substances. The UN 
Recommendations include new defining criteria for environmentally 
hazardous substances. The UN criteria have not yet been adopted by ICAO 
and IMO. We will consider these changes in a separate rulemaking 
proceeding.
     Hazardous materials security. Like the HMR, the UN 
Recommendations require carriers, consignors and others engaged in the 
transport of ``high consequence'' dangerous goods to adopt, implement 
and comply with a security plan that addresses the transportation risks 
associated with these materials. A major difference between the HMR and 
the UN Recommendations is the quantity of hazardous material that 
triggers the requirement for a security plan. On September 21, 2006, 
PHMSA published an advance notice of proposed rulemaking (71 FR 55156) 
to consider revisions to the list of hazardous materials that triggers 
security plan requirements under the HMR. We will consider whether the 
HMR list should be harmonized with the UN Recommendations list as part 
of this initiative.
     Requirements for radioactive materials. We are not 
adopting provisions pertaining to the transportation of Class 7 
(radioactive) materials. Amendments to requirements pertaining to the 
transportation of Class 7 materials are based on changes contained in 
the International Atomic Energy Agency (IAEA) publication, ``IAEA 
Safety Standards Series: Regulations for the Safe Transport of 
Radioactive Materials.'' Due to their complexity, these changes will be 
addressed in a separate rulemaking.
     Default classification system for fireworks. We are not 
adopting these provisions of the UN Recommendations because we do not 
believe the UN classification system provides an equivalent level of 
safety to the current HMR requirements. Under the HMR, fireworks must 
be classed and approved by the Associate Administrator for Hazardous 
Materials Safety; the approvals are based on American Pyrotechnic 
Association Standard 87-1.
     Fuel cells. We are not adopting provisions for the 
carriage of fuel cell cartridges in the passenger cabin of a passenger 
aircraft that were adopted by ICAO. Also, we are not adopting the 
packaging provisions for the transport of ``Hydrogen in a metal hydride 
storage system,'' (UN3468), as adopted by ICAO. Currently, the HMR 
allow

[[Page 78598]]

transportation of these storage systems by motor vehicle and rail under 
the terms of a special permit and by motor vehicle, rail, cargo vessel 
and cargo aircraft with approval of the Associate Administrator. These 
issues will be considered in a separate rulemaking proceeding.
     Marking of Limited Quantity shipments. The ICAO Technical 
Instructions include a marking requirement for packages containing a 
limited quantity of hazardous material. The mark consists of the 
identification number of the material placed within a square-on-point 
border. The marking is anticipated to become effective January 1, 2009. 
Except for transportation by aircraft, this marking is currently 
authorized under the HMR as an alternative to marking the proper 
shipping name on the package; we are allowing continued use of this 
marking to minimize transportation costs and provide flexibility.

III. Section-by-Section Review

Part 171

Section 171.7

    Section 171.7 lists the standards incorporated by reference into 
the HMR. We are updating the incorporation by reference materials for 
the ICAO Technical Instructions, the IMDG Code, the UN Recommendations 
and the UN Manual of Tests and Criteria. The updated editions of these 
standards become effective January 1, 2007. We did not receive comments 
opposing these incorporations by reference; therefore the standards are 
updated as follows:
     The ICAO Technical Instructions, 2007-2008 Edition.
     The IMDG Code, Amendment 33-06.
     The UN Recommendations, Fourteenth revised edition.
     The UN Manual of Tests and Criteria, Fourth revised 
edition (2003), and Addendum 2 (2004).

Section 171.14

    This section lists specific transition periods for certain 
provisions adopted into the HMR. Comments pertaining to transition 
periods are discussed below.
    Paragraph (b) lists transitional provisions related to revised 
placarding requirements. In this final rule, we are removing paragraph 
(b) because the transition period has expired.
    Paragraph (d) of this section specifies transitional provisions for 
previously adopted amendments intended to harmonize the HMR with 
international standards. We are revising this paragraph to provide 
specific transitional provisions for certain amendments in this final 
rule. The effective date of this final rule is January 1, 2007, and the 
mandatory compliance date is January 1, 2008. We are permitting 
voluntary compliance as of January 1, 2007, to correspond with the 
effective implementation dates of the 2007-2008 ICAO Technical 
Instructions and Amendment 33-06 of the IMDG Code. This authorization 
allows shippers to prepare their international shipments in accordance 
with international standards that will become effective on January 1, 
2007.
    Paragraph (e) of this section contains an outdated transitional 
provision. In this final rule, we are replacing the outdated 
transitional provision with a new paragraph (e) that permits use for 
domestic shipments of the shipping description sequences in effect on 
December 31, 2006, until January 1, 2013. See the Sec.  172.202 
preamble discussion for a complete explanation of the shipping 
description sequence issue.
    Paragraph (f) of this section contains an outdated transitional 
provision. We are revising paragraph (f) by removing the current 
provision and adding a transitional provision to allow continued 
display of Division 5.2 labels and placards conforming to the 
specifications in effect on December 31, 2006, until January 1, 2014 
for transportation by highway and until January 1, 2011 for 
transportation by rail, vessel or aircraft. See the Sec. Sec.  172.407, 
172.427 and 172.552 preamble discussions for a complete explanation of 
this issue.
    In new paragraph (g), we are allowing continued use of the Class 3 
and Division 6.1 classification criteria and packing group assignments 
in effect on December 31, 2006, until January 1, 2012. See Sec. Sec.  
173.120 and 174.133 preamble discussions for a complete explanation of 
this issue.

Part 172

Section 172.101

    Section 172.101 contains the Hazardous Materials Table (HMT) and 
explanations for each of the columns in the HMT. Paragraph (d) of this 
section addresses column 3 of the HMT containing the hazard class or 
division for each specific material listed in the HMT. Paragraph (d)(4) 
addresses entries classed as combustible liquids. In the NPRM, we 
proposed to revise paragraph (d)(4) to revise the lower limit for 
classing a material as a combustible liquid from 60.5 [deg]C (141 
[deg]F) to 60 [deg]C (140 [deg]F). This is consistent with recent 
changes to the classification of flammable liquids based on the 
adoption of the GHS within the UN Recommendations. We did not receive 
comments opposing this proposal; therefore, it is adopted in this final 
rule.
The Sec.  172.101 Hazardous Materials Table (HMT)
    In this final rule, we are making various amendments to the Sec.  
172.101 Hazardous Materials Table (HMT). Readers should review all 
changes for a complete understanding of the Table 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, will appear as a 
``remove'' and ``add.'' We did not receive comments opposing the 
changes to the HMT proposed in the NPRM. Therefore, in this final rule 
we are adopting the following amendments to the HMT for the purpose of 
harmonizing with international standards:
    1. We are correcting Column (7) Special provisions of the HMT by 
removing Special Provision 101 which requires the name of the 
particular substance or article to be specified. With the introduction 
of the letter ``G'' for these materials in Column (1), requiring the 
n.o.s. and generic proper shipping names to be supplemented with the 
technical name of the hazardous material, Special Provision 101 becomes 
obsolete and duplicative. The affected entries are as follows:

UN0349 Articles, explosive, n.o.s.
UN0350 Articles, explosive, n.o.s.
UN0351 Articles, explosive, n.o.s.
UN0352 Articles, explosive, n.o.s.
UN0353 Articles, explosive, n.o.s.
UN0354 Articles, explosive, n.o.s.
UN0355 Articles, explosive, n.o.s.

UN0466 Articles, explosive, n.o.s.
UN0467 Articles, explosive, n.o.s.
UN0468 Articles, explosive, n.o.s.
UN0469 Articles, explosive, n.o.s.
UN0470 Articles, explosive, n.o.s.
UN0471 Articles, explosive, n.o.s.
UN0472 Articles, explosive, n.o.s.
UN0382 Components, explosive train, n.o.s.
UN0383 Components, explosive train, n.o.s.
UN0384 Components, explosive train, n.o.s.
UN0461 Components, explosive train, n.o.s.
UN0357 Substances, explosive, n.o.s.
UN0358 Substances, explosive, n.o.s.
UN0359 Substances, explosive, n.o.s.
UN0473 Substances, explosive, n.o.s.
UN0474 Substances, explosive, n.o.s.
UN0475 Substances, explosive, n.o.s.
UN0476 Substances, explosive, n.o.s.
UN0477 Substances, explosive, n.o.s.

[[Page 78599]]

UN0478 Substances, explosive, n.o.s.
UN0479 Substances, explosive, n.o.s.
UN0480 Substances, explosive, n.o.s.
UN0481 Substances, explosive, n.o.s.
UN0485 Substances, explosive, n.o.s.
UN0482 Substances, explosive, very insensitive, n.o.s. or 
Substances, EVI, n.o.s.

    2. Amendment 32 of the IMDG Code added a new segregation group for 
alkalis. For consistency with international regulations and in response 
to a petition from Horizon Lines (P-1470), we are revising the Vessel 
stowage provisions in Column (10B) by adding Segregation Code ``52'' 
(Stow ``Separated from'' acids) to certain entries. The affected 
entries are as follows:

UN2733 Amines, flammable, corrosive, n.o.s. or Polyamines, 
flammable, corrosive, n.o.s.
UN2671 Aminopyridines (o-; m-; p-)
UN1005 Ammonia, anhydrous
UN3318 Ammonia solution, relative density less than 0.880 at 15 
degrees C in water, with more than 50 percent ammonia

    3. The entry ``Aerosols, non-flammable, (each not exceeding 1 L 
capacity),'' UN1950, is revised by adding vessel storage location code 
``A'' in Column (10A). This code was inadvertently removed in a final 
rule published September 23, 2005 under Docket HM-189Y (70 FR 56084).
    4. The entry ``Antimony trichloride, solid,'' UN1733, PG II, is 
revised by adding Special Provisions T3 and TP33. Special Provision T3 
specifies the applicable minimum test pressure, the minimum shell 
thickness, bottom opening requirements and pressure relief requirements 
when transporting this material in a UN portable tank. Special 
Provision TP33 specifies requirements applicable to the transportation 
of this material in IM and UN Specification portable tanks.
    5. The entry, ``Articles, explosive, extremely insensitive or 
Articles, EEI,'' UN0486, is revised by removing Special Provision 101 
which requires the name of the particular substance or article to be 
specified.
    6. The entry ``Benzyl bromide,'' UN1737, PG II, is revised by 
removing the reference to Sec.  173.153 ``Exceptions for Division 6.1 
(poisonous materials)'' in Column (8A).
    7. The entry ``Benzyl chloride,'' UN1738, PG II, is revised by 
removing the reference to Sec.  173.153 ``Exceptions for Division 6.1 
(poisonous materials)'' in Column (8A).
    7a. The entry ``Calcium hypochlorite, hydrated or Calcium 
hypochlorite, hydrated mixtures,'' UN2880, PG II, is revised by 
removing Special Provision 166.
    8. In accordance with changes in the Fourteenth revised edition of 
the UN Recommendations, we are removing the following entries:

--``Carbon dioxide and nitrous oxide mixtures,'' UN1015;
--``Carbon dioxide and oxygen mixtures, compressed,'' UN1014; and
--``Carbon monoxide and hydrogen mixture, compressed,'' UN2600.

    9. The entry, ``Charges, shaped, flexible, linear,'' UN0288, is 
revised by removing Special Provision 101, which requires the name of 
the particular substance or article to be specified.
    10. The entry ``Chlorosilanes, corrosive, n.o.s.,'' UN2987, PG II, 
is revised by removing the reference to Sec.  173.154 ``Exceptions for 
Class 8 (corrosive materials)'' in Column (8A).
    11. The entry ``Chlorosilanes, flammable, corrosive, n.o.s.,'' 
UN2985, PG II, is revised by removing the reference to Sec.  173.150 
``Exceptions for Class 3 (flammable) and combustible liquids'' in 
Column (8A).
    12. The entry ``Chlorosilanes, toxic, corrosive, n.o.s.,'' UN3361, 
PG II, is revised by removing the reference to Sec.  173.153 
``Exceptions for Division 6.1 (poisonous materials)'' in Column (8A).
    13. The entry ``Chlorosilanes, toxic, corrosive, flammable, 
n.o.s.,'' UN3362, PG II, is revised by removing the reference to Sec.  
173.153 ``Exceptions for Division 6.1 (poisonous materials)'' in Column 
(8A).
    14. The entry ``Chromium trioxide, anhydrous,'' UN1463, Column (6) 
is revised by adding the Division 6.1 subsidiary hazard labeling 
requirement.
    15. The entry ``Compressed gas, n.o.s.,'' UN1956, is revised by 
adding Special Provision 77. Special Provision 77 requires, for 
domestic transportation, a Division 5.1 subsidiary risk label when a 
carbon dioxide and oxygen mixture contains more than 23.5% oxygen.
    16. The entry, ``Contrivances, water-activated, with burster, 
expelling charge or propelling charge,'' UN0248, is revised by removing 
Special Provision 101, which requires the name of the particular 
substance or article to be specified. In addition, the letter ``G'' is 
added to Column (1), requiring the proper shipping name to be 
supplemented with the technical name of the hazardous material.
    17. The entry, ``Contrivances, water-activated, with burster, 
expelling charge or propelling charge,'' UN0249, is revised by removing 
Special Provision 101, which requires the name of the particular 
substance or article to be specified. In addition, the letter ``G'' is 
added to Column (1), requiring the proper shipping name to be 
supplemented with the technical name of the hazardous material.
    18. The entry ``Corrosive liquid, acidic, inorganic, n.o.s.,'' 
UN3264, PG II, is revised by removing Special Provision A6. Special 
Provision A6 specifies that for combination packagings, if plastic 
inner packagings are used, they must be packed in tightly closed metal 
receptacles before packing in outer packagings. Special Provision A6 
applies only to the PG I entry of this material.
    19. The proper shipping name for the entry ``Crotonaldehyde, 
stabilized,''

[[Page 78600]]

UN1143, is revised to read ``Crotonaldehyde or Crotonaldehyde, 
stabilized'' and to add new Special Provision 175. New Special 
Provision 175 specifies this material is required to be stabilized when 
in concentrations of not more than 99%. The revision appears as a 
``Remove/Add'' in this rulemaking.
    20. The proper shipping name for the entry ``Crotonic acid, 
liquid,'' UN2823, is corrected to read ``Crotonic acid, liquid'' and 
the Identification Number is revised to read ``UN3472.'' This revision 
appears as a ``Remove/Add'' in this rulemaking.
    21. The proper shipping name for the entry ``Crotonic acid, 
solid,'' UN2823, is corrected to read ``Crotonic acid, solid,'' UN2823. 
This correction appears as a ``Remove/Add'' in this rulemaking.
    22. In accordance with the ICAO Technical Instructions, the entry 
``Dangerous Goods in Machinery or Dangerous Goods in Apparatus,'' 
UN3363, is revised by adding quantity limits for transportation by 
aircraft. The quantity limits are specified in new Special Provision 
A105.
    23. The entry ``Ethyltrichlorosilane,'' UN1196, PG II, is revised 
by removing the reference to Sec.  173.150 ``Exceptions for Class 3 
(flammable) and combustible liquids'' in Column (8A).
    24. The entry ``Formic acid,'' UN1779, is revised to read ``Formic 
acid with more than 85% acid by mass,'' and the Class 3 subsidiary 
hazard is added in Column (6). This revision appears as a ``Remove/
Add'' in this rulemaking.
    25. A new entry, ``Formic acid with not less than 10% but not more 
than 85% acid by mass,'' UN3412, is added.
    26. A new entry, ``Formic acid with not less than 5% but less than 
10% acid by mass,'' UN3412, is added.
    27. A new entry, ``Fuel cell cartridges containing flammable 
liquids,'' UN3473, is added.
    28. The entry ``Hydrazine aqueous solutions, with more than 37% 
hydrazine, by mass,'' UN2030, PG I, is revised by removing Special 
Provision 151. Special Provision 151 specifies that if this material 
meets the definition of a flammable liquid in 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. Changes to 
the Fourteenth revised edition of the UN Recommendations removed this 
requirement. Shipping paper and labeling requirements for materials 
with subsidiary hazards are addressed in Sec. Sec.  172.202 and 
172.402, respectively.
    28a. The entry ``Hydrogen in a metal hydride storage system,'' 
UN3468, is revised by amending Column (9B) to authorize 100 kg gross.
    29. The entry ``Hydrogen peroxide and peroxyacetic acid mixtures, 
stabilized with acids, water, and not more than 5 percent peroxyacetic 
acid,'' UN3149, is revised by adding Special Provision IP5. When this 
material is transported in an IBC, Special Provision IP5 specifies the 
IBC must have a device to allow venting.
    30. The entry ``Hydrogen peroxide, aqueous solutions with more than 
40 percent but not more than 60 percent hydrogen peroxide (stabilized 
as necessary),'' UN2014, is revised by adding Special Provision IP5. 
When this material is transported in an IBC, Special Provision IP5 
specifies the IBC must have a device to allow venting.
    31. The entry ``Hydrogen peroxide, aqueous solutions with not less 
than 20 percent but not more than 40 percent hydrogen peroxide 
(stabilized as necessary),'' UN2014, is revised by adding Special 
Provision IP5. When this material is transported in an IBC, Special 
Provision IP5 specifies the IBC must have a device to allow venting.
    32. The entry ``Hydrogen peroxide, aqueous solutions with not less 
than 8 percent but less than 20 percent hydrogen peroxide (stabilized 
as necessary),'' UN2984, is revised by adding Special Provision IP5. 
When this material is transported in an IBC, Special Provision IP5 
specifies the IBC must have a device to allow venting.
    33. The entry ``Hydrogen peroxide, stabilized or Hydrogen peroxide 
aqueous solutions, stabilized with more than 60 percent hydrogen 
peroxide,'' UN2015, is revised by removing Special Provision T10 and 
adding Special Provision T9. When this material is transported in a UN 
portable tank, Special Provision T10 requires the UN portable tank 
pressure relief device to comply with the requirements specified in 
Sec.  178.275(g)(3) of the HMR. The addition of Special Provision T9 
removes this requirement.
    34. For the entry ``Hydrogen-difluorides, n.o.s.,'' UN1740, PG II 
and III, the proper shipping name is revised to read 
``Hydrogendifluorides, solid, n.o.s.'' This revision appears as a 
``Remove/Add'' in this rulemaking.
    35. A new entry ``Hydrogendifluorides, solution, n.o.s.,'' UN3471, 
PG II and III, is added.
    36. The entry ``Hydroquinone, solid,'' UN2662, is removed.
    37. The entry ``Hydroquinone solution,'' UN3435, is removed.
    38. The entry ``Hypochlorite solutions,'' UN1791, PG II, is revised 
by adding Special Provision IP5. When this material is transported in 
an IBC, Special Provision IP5 specifies the IBC must have a device to 
allow venting.
    39. For the entry ``Lead phosphite, dibasic,'' UN2989, PG II, the 
quantity limitations in Columns (9A) and (9B) are revised to read 15 kg 
and 50 kg, respectively.
    40. For the entry ``Lead phosphite, dibasic,'' UN2989, PG III, the 
quantity limitations in Columns (9A) and (9B) are revised to read 25 kg 
and 100 kg, respectively.
    41. The entry ``Methylphenyl dichlorosilane,'' UN2437, PG II, is 
revised by removing the reference to Sec.  173.154 ``Exceptions for 
Class 8 (corrosive materials)'' in Column (8A).
    42. The entry ``Motor fuel anti-knock mixtures,'' UN1649, is 
corrected by removing the subsidiary hazard label requirement in Column 
(6).
    42a. A new entry ``Nitric acid other than red fuming, with not more 
than 20 percent nitric acid,'' UN2031, PG II, is added.
    42b. The entry ``Organoarsenic compound, liquid, n.o.s.,'' UN3280, 
PG I, II, and III, is corrected by inserting the symbol ``G'' in Column 
(1).
    43. The entry ``Organometallic substance, solid, pyrophoric,'' 
UN3391, PG I, is revised by correcting the Column (8B) Non-bulk 
packaging entry ``181'' to read ``187.''
    44. The entry ``Organometallic substance, solid, pyrophoric, water-
reactive,'' UN3393, PG I, is revised by correcting the Column (8B) Non-
bulk packaging entry ``181'' to read ``187.''
    45. A new entry, ``Paint, corrosive, flammable (including paint, 
lacquer, enamel, stain, shellac, varnish, polish, liquid filler and 
liquid lacquer base),'' UN3470, PG II, is added.
    46. A new entry ``Paint, flammable, corrosive (including paint, 
lacquer, enamel, stain, shellac, varnish, polish, liquid filler and 
liquid lacquer base),'' UN3469, PG I, II, and III, is added.
    47. The entry ``Paint including paint, lacquer, enamel, stain, 
shellac solutions, varnish, polish, liquid filler and liquid lacquer 
base,'' UN1263, is revised by adding the following Special Provisions 
to the PG I, II, and III entries, respectively:

--TP27 to specify that when this material is transported in an IM or UN 
Specification portable tank, a portable tank having a minimum test 
pressure of 4 bar (400 kPa) may be used provided the calculated test 
pressure is 4 bar or less based on the maximum allowable working

    48. The entry ``Paint or Paint related materials,'' UN3066, is 
revised by adding the following Special Provisions to the PG II and III 
entries, respectively:

--TP28 to specify that when this material is transported in an IM or UN 
Specification portable tank, a portable tank having a minimum test 
pressure of 2.65 bar (265 kPa) may be used provided the calculated test 
pressure is 2.65 bar or less based on the maximum allowable working 
pressure of the material, as defined in Sec.  178.275 of the HMR, where 
the test pressure is 1.5 times the maximum allowable working pressure.
--TP29 to specify that when this material is transported in an IM or UN

--TP28 to specify that when this material is transported in an IM or UN 
Specification portable tank, a portable tank having a minimum test 
pressure of 2.65 bar (265 kPa) may be used provided the calculated test 
pressure is 2.65 bar or less based on the maximum allowable working 
pressure of the material, as defined in Sec.  178.275 of the HMR, where 
the test pressure is 1.5 times the maximum allowable working pressure.
--TP29 to specify that when this material is transported in an IM or UN

test pressure is 1.5 bar or less based on the maximum allowable working 
pressure of the material, as defined in Sec.  178.275 of the HMR, where 
the test pressure is 1.5 times the maximum allowable working pressure.

    52. The entry ``Plastic molding compound in dough, sheet or 
extruded rope form evolving flammable vapor, UN3314, PG III, is revised 
by removing Vessel stowage location A and adding location E in Column 
(10A), and by removing Vessel stowage provision 85 and adding Vessel 
stowage provisions 19, 21, 25 and new Vessel stowage provision 144 in 
Column (10B).
    53. The entry ``Polymeric beads, expandable, evolving flammable 
vapor, UN2211, PG III, is revised by removing stowage location A and 
adding location E in Column (10A), and by removing Vessel stowage 
provision 85 and adding Vessel stowage provisions 19, 21, 25 and new 
Vessel stowage provision 144 in Column (10B).
    54. For the entry ``Propionic acid,'' UN1848, the proper shipping 
name is revised to read, ``Propionic acid with not less than 10% and 
less than 90% acid by mass.'' This revision appears as a ``Remove/Add'' 
in this rulemaking.
    55. A new entry, ``Propionic acid with not less than 90% acid by 
mass,'' UN3463, is added.
    56. The entry ``Rare gases mixtures, compressed,'' UN1979, is 
removed.
    57. The entry ``Rare gases and oxygen mixtures, compressed,'' 
UN1980, is removed.

UN1981, is removed.
    59. The proper shipping name ``Regulated medical waste,'' UN3291, 
is removed and a new proper shipping name ``Regulated medical waste, 
n.o.s. or Clinical waste unspecified, n.o.s. or (BIO) Medical waste, 
n.o.s.,'' UN3291, is added in its place.
    60. For the international entry for ``Sulfur,'' UN1350, the 
quantity limitations in Columns (9A) and (9B) are revised to read 25 kg 
and 100 kg, respectively.
    61. The entry ``Trimethylchloro-silane,'' UN1298, PG II, is revised 
by removing the reference to Sec.  173.150 ``Exceptions for Class 3 
(flammable) and combustible liquids'' in Column (8A).
    Also, see Sec.  172.102 for additional HMT amendments.

Appendix B to Sec.  172.101

    Appendix B to Sec.  172.101 lists Marine Pollutants regulated 
under the HMR. For the entry ``Copper chloride'' we are adding the 
designation ``PP'' to indicate that copper chloride is a severe 
marine pollutant. We are also correcting an oversight by removing 
the entries ``Alcohol C-13--C-15 poly (1-6) ethoxylate'' and ``1,2-
Dichlorobenzene.'' Removal of the entry ``Alcohol C-13--C-15 poly 
(1-6) ethoxylate'' was overlooked in a final rule published December 
20, 2004 under Docket HM-215G (69 FR 76044) and removal of the entry 
``1,2-Dichlorobenzene'' was overlooked in a final rule published 
June 21, 2001 under Docket HM-215D (66 FR 33316).

Section 172.102

    Section 172.102 lists a number of special provisions applicable to 
the transportation of specific hazardous materials. Special provisions 
contain packaging provisions, prohibitions, and exceptions applicable 
to particular quantities or forms of hazardous materials. We did not 
receive comments opposing the revisions proposed in the NPRM; 
therefore, in this final rule for consistency with international 
standards, we are amending Sec.  172.102 Special provisions, as 
follows:
     Special Provision 15 specifies the types of materials and 
packaging requirements for chemical kits and first aid kits. We are 
revising Special Provision 15 to list examples that may be described as 
``Chemical kits'' and ``First aid kits.''
     Special Provision 47 specifies requirements for mixtures 
of non-hazardous solids and flammable liquids. In accordance with the 
UN Recommendations, Special Provision 47 is revised to specify that, in 
addition to sealed packets, articles containing less than 10 mL of a 
Class 3 Packing Group

[[Page 78602]]

II or III liquid absorbed into a solid material are excepted from the 
HMR provided there is no free liquid in the packet or article.
     Special Provision 77 applies to use of the Division 5.1 
subsidiary risk label. We are revising this special provision for 
consistency with the wording in the UN Recommendations. As a result, 
Special Provision 77 will no longer apply only to ``domestic 
transportation.'' Further, we are clarifying that a Division 5.1 label 
is not required for mixtures containing not more than 23.5% oxygen by 
volume. Also, the provision is assigned to the entry ``Compressed gas, 
n.o.s.,'' UN1956, which is the most appropriate description for 
mixtures currently described as ``Carbon dioxide and oxygen mixtures, 
compressed.'' In this final rule, we are removing the entry for 
``Carbon dioxide and oxygen mixtures, compressed.''
     Special Provision 146 is amended to authorize the domestic 
classification of a material as environmentally hazardous if it is 
designated as such by a foreign competent authority. The provision as 
currently worded only allows such classification for international 
shipments. Due to current differences in criteria for the 
classification of environmentally substances world-wide, we believe the 
amended provision will afford additional flexibility to industry and 
reduce shipping costs by allowing both domestic and international 
shipments to be treated identically. Although generally the HMR do not 
authorize materials not meeting the definition of a hazardous material 
to be transported as regulated materials, due to the low risk posed by 
these materials, and the fact that the HMR already authorize domestic 
movement in association with international air and vessel transport, we 
believe this change will not result in a significant impact other than 
to lower costs for our stakeholders.
     Special Provision 147 applies to non-sensitized emulsions, 
suspensions and gels consisting primarily of a mixture of ammonium 
nitrate and fuel, intended to produce a Type E blasting explosive only 
after further processing prior to use. In accordance with the UN 
Recommendations, this special provision is revised to specify the 
composition of mixtures for suspensions and gels and to specify these 
substances be tested in accordance with Test Series 8 of the UN Manual 
of Tests and Criteria.
     Special Provision 166 authorizes non-friable, tablet form 
calcium hypochlorite, dry or hydrated, to be transported as a Packing 
Group III material. In accordance with the UN Recommendations, we are 
revising Special Provision 166 to remove the authorization for 
``hydrated'' non-friable tablet forms of calcium hypochlorite to be 
transported as a PG III material.
     A new Special Provision 175 is added to require 
stabilization for certain substances when transported in concentrations 
of not more than 99%.
     Special Provision 101 is removed. This special provision 
required the name of the particular substance or article to be 
specified. With the introduction of the letter ``G'' in Column (1), 
which requires the n.o.s. and generic proper shipping names to be 
supplemented with the technical name of the hazardous material, Special 
Provision 101 became obsolete.
     A new Special Provision A105 is added to specify the 
quantity of hazardous materials allowed in equipment or apparatus.

Section 172.202

Shipping Description Sequence
    Section 172.202 establishes requirements for shipping descriptions 
on shipping papers. Currently, the basic description of a hazardous 
material consists of the proper shipping name, hazard class, ID number 
and packing group, in that order. The HMR also authorize an alternative 
description sequence, which lists the identification number first, 
followed by the proper shipping name, hazard class, and packing group. 
Beginning January 1, 2007, the alternative shipping description 
sequence will be mandatory on shipping documents prepared in accordance 
with the ICAO Technical Instructions and the IMDG Code. In the NPRM, we 
proposed to adopt the current, alternative shipping description 
sequence as the mandatory basic description of a hazardous material on 
a shipping paper. We also proposed a two-year transition period to 
allow offerors adequate time to convert to the new shipping description 
sequence.
    A total of 19 commenters addressed this proposal. Eight commenters 
[NPCA, AP&C, ATA, GPS, LabCorp, NTTC, UPS, and VHOMA] support the 
proposal. NPCA notes that many of its members have already implemented 
this change to simplify internal shipping processes.
    Eleven commenters [Adamo; AllChem; Botteri; Eisenhofer; ISSA, J&S; 
NACD; NATC; RST; and two unidentified commenters] oppose this proposal, 
suggesting that the change is not necessary, lacks an economic 
justification, and will have a negative impact on safety. These 
commenters note that, because the current regulations allow the 
international sequence as an alternative, the proposed change merely 
removes the existing sequence with no positive safety rationale. These 
commenters further assert that the proposed change could result in 
significant cost impacts to companies that utilize computer systems for 
the preparation of shipping documents and to track associated packaging 
and training requirements. According to these commenters, potential 
costs could include database reorganization, employee training, and 
related revisions to product labels that also include shipping 
information. Commenters suggest that costs could also result from 
confusion on the part of enforcement and inspection personnel that 
could lengthen inspections and delay shipments. These commenters are 
also concerned that the proposed revision could have a negative impact 
on safety because it could result in confusion for emergency response 
personnel, most of whom are volunteers and receive limited training. 
Commenters note that confusing emergency response information could 
expose emergency responders to unnecessary danger.
    PHMSA does not believe this proposal is unnecessary or will 
adversely impact transportation safety. A uniform system for describing 
and identifying hazardous materials on shipping papers, as proposed in 
this NPRM, will increase safety by helping to eliminate potential 
indecision and confusion during emergency situations. For example, when 
incidents occur during transportation, it is crucial to promptly 
identify packages of hazardous materials present in a given shipment. 
Emergency responders at the scene of an incident would use a standard 
description of hazardous materials on shipping papers to quickly 
determine that they have accounted for all hazardous materials in both 
domestically- and internationally-bound packages. In addition, 
following the release of a hazardous material, it is vital for 
emergency responders to quickly identify the hazardous materials to 
facilitate their emergency response decision-making. A standardized 
shipping description for both domestic and international shipments will 
aid in this process and will lead to a potential reduction in the loss 
of life and property.
    PHMSA analyzes potential cost impacts of proposed regulations on 
the regulated community. Our justification regarding this proposal in 
the Regulatory Evaluation is located under the Docket Management System 
(http://dms.dot.gov). In the Regulatory

[[Page 78603]]

Evaluation, we determined that this NPRM, including this specific 
proposal, should result in cost savings by easing the regulatory 
compliance burden for shippers and carriers engaged in international 
commerce, including trans-border shipments within North America. In 
addition, shippers and carriers will not need to revise shipping papers 
to address differing domestic and international requirements for 
shipping descriptions. We acknowledge the proposal to require one basic 
description of a hazardous material on a shipping paper will 
necessitate additional training and software revisions. However, to 
allow for the training of hazmat employees and to ease the minimal 
burden on entities affected by the adoption of the proposed amendments, 
we are authorizing an extended transition period. An extended 
transition period will allow businesses to incorporate this requirement 
into their training material for both new and current hazardous 
materials employees, and to upgrade system software over the course of 
normal computer upgrades and revisions with a minimal economic impact.
    The NPRM proposed a two-year transition period to allow shippers 
sufficient time to convert to the new shipping description sequence. 
Three commenters [NTTC, ATA, and VOHMA] suggest the proposed transition 
period is unnecessary and recommend a one-year transition. These 
commenters state that the industry is able to alter current software 
systems and deplete pre-printed shipping paper inventory within a 
relatively short time period. VOHMA asserts lengthy transition periods 
create confusion and increased training burdens. Six commenters [ATA; 
GPS; LabCorp; NTTC; UPS; VOHMA] state that the proposed transition 
period is too short, recommending up to six years to permit shippers to 
convert to the new sequence. These commenters suggest a longer 
transition period would allow the new shipping sequence to be 
incorporated into responder training programs and the next revision of 
the Emergency Response Guidebook (ERG). The ERG lists hazardous 
materials in numerical order of ID number and in alphabetical order of 
material name.
    We understand commenters' concerns regarding the length of the 
transition period for this proposal. However, it is our intention to 
specify a uniform method to describe a hazardous material on a shipping 
paper in order to promote the universal recognition of hazardous 
materials, while allowing sufficient time for affected parties to 
properly train personnel, reconfigure internal computer systems, and 
deplete existing stock. We do not believe a time period less than six 
years would allow businesses to adequately accomplish these objectives. 
Moreover, a six-year transition period would allow for the 
incorporation of this requirement into the initial and recurrent 
training cycle for hazardous materials employees and emergency 
responders.
    Therefore, for the reasons described above, in this final rule, we 
are adopting the requirement that the shipping description of a 
hazardous material be indicated on a shipping paper in the following 
manner: Identification (ID) number listed first, followed by the proper 
shipping name, hazard class, and packing group. In addition, we are 
authorizing a six-year transition period to implement this requirement.
Quantity Limitations
    The description of a hazardous material on a shipping paper must 
include the total quantity of hazardous material (by mass or volume) 
covered by the description (see Sec.  172.202(a)(5)). The majority of 
quantity limitations set forth for transportation by aircraft, in 
Columns (9A) and (9B), are ``net'' quantities. Section 175.75 limits 
the quantity of hazardous materials, expressed in net mass, aboard an 
aircraft. To facilitate compliance with the aircraft operator's 
requirements, in the NPRM we proposed that, for transportation by 
aircraft, the total quantity per package be shown, expressed as net 
mass, except as otherwise specified. For example:
    UN1263, Paint, 3, PG II, 5 fiberboard boxes x 5 L each
    As proposed, different size packages containing different 
quantities of the same hazardous material must be clearly identified. 
For example:
    UN1263, Paint, 3, PG II, 5 fiberboard boxes x 5 L, 6 fiberboard 
boxes x 10 L
    As proposed, where the letter ``G'' follows the quantity in Column 
(9A) or (9B), the gross mass rather than the net quantity must be 
indicated.
    A commenter [DGAC] opposes the proposal to require the quantity of 
a hazardous materials shipment by aircraft to be expressed as a net 
quantity per package. The commenter questions the safety benefit of 
adopting the requirement and states that the costs to industry 
associated with the change, such as computer software upgrades, may be 
substantial. The commenter did not provide data to support this 
argument. We disagree that there is no safety benefit in expressing the 
quantity of hazardous material in terms of ``net quantity'' for air 
shipments. Quantity limitations aboard aircraft, as prescribed in Sec.  
175.75, are specified in the HMR as net quantities; thus, an indication 
of the net quantity per package on shipping papers facilitates load 
planning and compliance. We do not believe the cost of indicating net 
quantity rather than total quantity, as previously required, is 
increased substantially. Therefore, in this final rule, we are adopting 
the amendment as proposed.
    In the NPRM, we also proposed the following additional 
requirements:

--For empty uncleaned packaging, only the number and type of packaging 
must be shown;
--For chemical kits and first aid kits, the total net mass of hazardous 
materials must be shown. Where a kit contains solids and/or liquids, 
the net mass of liquids within the kit is to be calculated on a 1 to 1 
basis, i.e., 1 liter equals 1 kilogram;
--For dangerous goods in machinery or apparatus, the individual total 
quantities of dangerous goods in solid, liquid or gaseous state, 
contained in the article must be shown;
--For dangerous goods transported in a salvage packaging, an estimate 
of the quantity of dangerous goods per package must be shown;
--For cylinders, the total quantity may be indicated by the number of 
cylinders, for example, ``10 cylinders;''
--For items where ``No Limit'' is shown in Column (9A) or (9B) of the 
HMT, the quantity shown should be the net mass or volume of the 
material, except for UN2800, UN2807, UN3072, UN3166 and UN3173, where 
the quantity should be the gross mass of the article.

    On the proposal to identify the total quantity of each hazardous 
material in machinery or apparatus, a commenter [UPS] states that the 
``precision implied in this proposal is unrealistic.'' UPS suggests 
that, absent a precise quantity, a shipper should be permitted to 
estimate the quantity of hazardous material. We agree and are amending 
paragraph (a)(6)(iii) accordingly.
    Another commenter [Laude] requests we include net quantity 
provisions for Class 7 materials transported by aircraft. Similar 
provisions for transportation by other modes are contained in paragraph 
(a)(5). We agree with the commenter and are amending paragraph (a)(6) 
accordingly.
    The same commenter points out that in proposed paragraph (a)(6)(vi) 
ID numbers UN2807 and UN3173 do not exist in the HMT; (ID number UN2807 
is assigned to ``magnetized material'' in the ICAO Technical 
Instructions). We are removing UN2807 and UN3173 in this final rule.

Section 172.312

    Section 172.312 addresses marking requirements for liquid hazardous 
materials in non-bulk packagings. Specifically, the packaging must be 
marked with orientation arrows to indicate how the package should be 
oriented during transportation; the arrows indicate which end of the 
package is ``up.'' Currently the HMR require orientation markings only 
on a non-bulk combination package with inner packagings that contain a 
liquid hazardous material, unless specifically excepted.
    We proposed to amend paragraph (a) by requiring orientation 
markings on single packagings fitted with vents and on open cryogenic 
receptacles intended for the transport of refrigerated liquefied gases. 
We received one comment [AP&C] supporting the proposal and, in this 
final rule, are adopting the amendment as proposed.
    Also, we proposed to require the size of the marking to be 
proportioned so that it is clearly visible in relation to the size of 
the package, and the color of the arrows to be either black or red on a 
suitable contrasting background. One commenter [AP&C] supports the 
proposal requiring the size of the marking to be proportionate with the 
size of the package. Several commenters [NATC; Botteri; Eisenhofer; 
Adamo; NACD; J&S; RST; AllChem; UC1; UC2] question the meaning of the 
phrase ``clearly visible'' and suggest we specify the size of the 
marking; either by requiring the marking to be at least equal to the 
size of the largest package marking or, at a minimum, requiring the 
marking to be \1/2\ inch. We agree with commenters that the phrase 
``clearly visible'' is vague; however, we disagree with specifying the 
size of the orientation marking. The HMR currently require non-bulk 
packages containing liquid hazardous materials to be ``legibly marked'' 
with the orientation marking. Specifying the size of the orientation 
marking would be inconsistent with the general marking requirements 
(proper shipping name and identification number) for non-bulk 
packagings which do not specify the size of the markings. In this final 
rule, we are removing the phrase ``clearly visible'' and requiring the 
orientation marking to be commensurate with the size of the package.
    We also proposed adding a new paragraph (c)(7) to except Class 7 
materials in Type A, IP-2, IP-3, Type B(U), or Type B(M) packages from 
the orientation marking requirement. We received no comments on this 
proposal and are adopting the amendment as proposed.

Sections 172.407 and 172.427

    Section 172.407 establishes specifications for package labels. 
Section 172.427 establishes requirements for the ORGANIC PEROXIDE 
label. In accordance with the UN Recommendations, we proposed to revise 
the ORGANIC PEROXIDE label. The revised label would reflect the fact 
that organic peroxides are highly flammable and enable transport 
workers to readily distinguish peroxides from oxidizers. We also 
proposed to authorize labels meeting the specifications in effect on 
December 31, 2006, to continue to be displayed until January 1, 2011 
(see Sec.  171.14). This would eliminate the current requirement in 
Sec.  172.402 for a package containing an organic peroxide to bear a 
FLAMMABLE LIQUID subsidiary label in addition to the ORGANIC PEROXIDE 
primary hazard class label.
    We received no comments opposing the proposal to revise the ORGANIC 
PEROXIDE label; therefore, in this final rule we are adopting the 
revisions as proposed.

Section 172.552

    Section 172.552 establishes specific requirements for the ORGANIC 
PEROXIDE placard. In accordance with the UN Recommendations, in 
paragraph (b), we proposed to revise the ORGANIC PEROXIDE placard. The 
revised placard would reflect the fact that organic peroxides are 
highly flammable and enable transport workers to readily distinguish 
peroxides from oxidizers. We proposed to authorize placards meeting the 
specifications in effect on December 31, 2006, to continue to be 
displayed until January 1, 2011 (see Sec.  171.14).
    We received one comment [ATA] supporting the revised placard 
design; however, ATA disagrees with the length of the proposed 
transition period. The ATA requests a seven-year transition period 
until January 1, 2014. The ATA states that trucking companies with 
large fleets use dual metal flip placards on each side of the trailer. 
According to the ATA, trailer fleets are generally refurbished every 
seven years. This would allow companies to replace the ORGANIC PEROXIDE 
placard at the time of refurbishment. Based on this comment, in this 
final rule, we are authorizing ORGANIC PEROXIDE placards meeting the 
specifications in effect on December 31, 2006, to continue to be 
displayed until January 1, 2014 for transportation by highway and until 
January 1, 2011 for transportation by rail, vessel or aircraft.

Part 173

Section 173.9

    Section 173.9 sets forth requirements for transporting cargo that 
has been fumigated or is undergoing fumigation. Such shipments must 
have a FUMIGANT marking. As specified in this section, the FUMIGANT 
marking includes an indication of the material used for fumigation and 
the date and time the fumigant was applied. Currently, transport 
vehicles or freight containers containing fumigated cargoes are not 
required to show the date the fumigated transport vehicle or freight 
container was ventilated to remove harmful concentrations of fumigant 
gas. To minimize the possibility of an individual entering a fumigated 
transport vehicle or freight container prematurely, in the NPRM we 
proposed to require the FUMIGANT marking to include the date of 
ventilation. We also proposed to revise the specifications for the 
FUMIGANT marking to allow either red or black marking on a white 
background. No commenters opposed these proposals, therefore, we are 
adopting them without change in this final rule.

Sections 173.35, 173.120, 173.121, and Appendix H to Part 173

    Section 173.35 sets forth requirements for transporting hazardous 
materials in intermediate bulk containers (IBCs); Sec.  173.120 
establishes classification criteria for flammable liquid (Class 3) 
materials; Sec.  173.121 addresses packing group assignments for Class 
3 materials; and Appendix H to Part 173 sets forth methods to test a 
material to determine its combustibility. In the NPRM, we proposed to 
revise all of these sections to reflect the new upper limit of 60 
[deg]C (140 [deg]F) for a PG III flammable liquid. This is consistent 
with recent changes to the classification of flammable liquids based on 
the GHS and adoption into the UN Recommendations. PHMSA also proposed 
to authorize a five-year transition period.
    A commenter [DGAC] appreciates the length of the proposed 
transition period. DGAC urges PHMSA to propose a similar transition 
period for the criteria in international regulations. Modifications to 
the international standards are outside the scope of this rulemaking. 
International shippers should be aware of this disparity and take 
appropriate action. In this final rule, we are adopting the amendment 
as proposed.

[[Page 78605]]

Section 173.115

    The HMR define a Division 2.2 non-flammable gas as any material or 
mixture that ``exerts in the packaging an absolute pressure of 280 kPa 
(40.6 psia) or greater at 20 [deg]C (68 [deg]F), * * *.'' In paragraph 
(b)(1), we proposed to add the phrase ``or is a cryogenic liquid,'' to 
clarify that a cryogenic liquid, whether or not it meets the definition 
of a Division 2.2 non-flammable gas, is subject to the HMR. This is 
consistent with the current requirements for cryogenic liquids in Sec.  
173.115(g). We received no comments opposing this proposal; therefore, 
in this final rule, we are adopting the proposal without change.
    Currently, paragraph (k)(5) of this section requires aerosols 
containing Class 8, PG III materials to be assigned a Class 8 
subsidiary hazard. In the NPRM, we proposed to amend paragraph (k)(5) 
to specify that aerosols containing Class 8, PG II or PG III materials 
must be assigned a Class 8 subsidiary hazard. We received no comments 
opposing this proposal; therefore, in this final rule, we are adopting 
the proposal without change.

Section 173.124

    Section 173.124 establishes classification criteria for Division 
4.1 (flammable solid), Division 4.2 (spontaneously combustible), and 
Division 4.3 (dangerous when wet) materials. In the NPRM, we proposed 
to revise Sec.  173.124 by adding a new paragraph (a)(2)(i)(D)(3) to 
require mixtures of oxidizing substances containing 5.0% or more 
combustible organic substances to be subject to the self-reactive 
substance classification procedure. This will ensure that oxidizing 
substances containing 5.0% or more of combustible organic substances 
are also tested for their ability to self-react and to ensure that in 
such instances, these substances are appropriately classed for their 
self-reactive hazard. We received no comments on this proposal; it is 
adopted without change in this final rule.

Section 173.133

    Section 173.133 establishes criteria for assignment of packing 
groups to poisonous (Division 6.1) materials. We proposed to amend the 
toxicity criteria for consistency with the toxicity criteria adopted in 
the UN Recommendations on the basis of the limits established in the 
GHS. As a result, some materials that were not previously regulated 
under the HMR would now be regulated as Division 6.1, Packing Group 
III; some materials currently regulated as Division 6.1, Packing Group 
I or II are assigned to a different packing group; and some materials 
that were previously regulated as Division 6.1, Packing Group III would 
no longer be subject to regulation under the HMR. PHMSA also proposed a 
five-year transition period.
    The effect of these proposed changes to packing group assignments 
for Division 6.1 materials is summarized as follows:

----------------------------------------------------------------------------------------------------------------
       Material properties                  Current PG assignment                    New PG assignment
----------------------------------------------------------------------------------------------------------------
Oral LD50 > 200, <= 300 (Solid)..  Not regulated.........................  III
Oral LD50 > 300, <= 500 (Liquid).  III...................................  Not regulated.
Dermal LD50 > 40, <= 50..........  II....................................  I
Inhalation toxicity by dusts and   I.....................................  II
 mists LC50 > 0.2, <= 0.5.
Inhalation toxicity by dusts and   III...................................  Not regulated.
 mists LC50 > 4, <= 10.
----------------------------------------------------------------------------------------------------------------

    Thirteen commenters [NATC; Botteri; Eisenhofer; Adamo; J&S; RST; 
AP&C; AllChem; Arkema; UC1; UC2; NACD; DGAC] support adoption of this 
proposal. Arkema notes that the amended criteria may result in 
reclassification of certain materials that are listed by name in the 
HMT. The commenter requests that the HMR be amended to allow the use of 
currently listed names instead of describing the material under an 
appropriate generic (n.o.s.) name based on the new toxicity criteria. 
The commenter also states Arkema, an international company, will review 
its materials to ensure they are in compliance with the provisions of 
the 2008 IMDG Code, and will handle air shipments on a case-by-case 
basis. PHMSA does not intend to provide such an allowance in the HMR; 
we believe such a provision could be confusing and would be 
inconsistent with the international regulations. However, we invite 
submission of data supporting reclassification of certain materials 
resulting from the revised criteria for toxic materials. Such data 
could be used to effect change in the listing of a material within the 
HMR and the UN Model Regulations.
    A commenter [DGAC] appreciates the length of the proposed 
transition period. DGAC urges PHMSA to propose a similar transition 
period for the criteria in international regulations. Changes to the 
international standards are outside the scope of this rulemaking. 
International shippers should be aware of this disparity and take 
appropriate action.
    Finally, ten commenters [NATC; Botteri; Eisenhofer; Adamo; J&S; 
RST; AllChem; UC1; UC2; NACD] request a five-year transition period and 
a grandfather clause to allow packages filled prior to a specific date 
to remain marked without modification for domestic transportation. In 
the NPRM, we proposed a five-year transition period and in this final 
rule, we are adopting the amendment as proposed (see Sec.  171.14). We 
disagree with the request to allow packages filled prior to a specific 
date to remain marked without modification for domestic transportation. 
We believe that a five-year transition provides adequate time to 
transition to the new classification criteria and to ensure that 
packages marked based on regulations in effect on December 31, 2006, 
are out of the transportation stream. Therefore, we are not adopting a 
grandfather clause.

Sections 173.134 and 173.197

    Consistent with the proposals in the NPRM, in this final rule, 
these sections are revised by replacing the wording ``Regulated medical 
waste'' with the wording ``Regulated medical waste or clinical waste or 
(bio) medical waste.'' No commenters addressed this issue.

Section 173.136

    Currently, the HMR define ``corrosive material'' to mean ``a liquid 
or solid that causes full thickness destruction of human skin at the 
site of contact within a specified period of time. A liquid that has a 
severe corrosion rate on steel or aluminum based on the criteria in 
Sec.  173.137(c)(2) is also a corrosive material.'' Certain solids with 
a low melting point may become liquid during transportation, and others 
may be intentionally heated above their melting point and transported 
as a liquid in the molten state. We believe the Class 8 definition 
should apply equally to liquids and to solids offered for 
transportation or transported in a liquid state. In the NPRM, we 
proposed to revise the definition of a ``corrosive

[[Page 78606]]

material'' to include a solid material that is offered for 
transportation or transported as a liquid and has a severe corrosion 
rate on steel or aluminum. A commenter [Degussa] requests that we align 
the definition with the UN Recommendations. We agree and are modifying 
the definition of ``corrosive material'' to include the phrase ``solids 
that may become liquid during transportation.'' Also, we are removing 
the grandfather provision in Sec.  173.136(d) on the basis that it is 
no longer necessary because tests other than the one specified in the 
UN Manual of Tests and Criteria will be authorized. See the Sec.  
173.137 preamble discussion below.

Section 173.137

    Section 173.137 establishes packing group criteria for corrosive 
(Class 8) materials. In a final rule published December 20, 2004 under 
Docket HM-215G (69 FR 76155), we revised the language in paragraph 
(c)(2) mandating the corrosion test in the UN Manual of Tests and 
Criteria as the only acceptable test method for determining the 
corrosivity of a material. That was not our intent. In the NPRM, we 
proposed to revise paragraph (c)(2) to specify that corrosivity may be 
determined in accordance with methods described in the UN Manual of 
Tests and Criteria, as well as other equivalent methods, such as those 
described in ASTM G 31-72. No commenters addressed this proposal; it is 
adopted without change in this final rule.

Section 173.159

    Section 173.159 establishes transportation requirements for wet 
electric storage batteries. For consistency with the ICAO Technical 
Instructions, in the NPRM we proposed to revise paragraphs (a), (c)(1), 
(c)(2), (c)(4), (c)(5), (d)(1) and (e)(2) to clarify that batteries may 
be protected against short circuits by the use of non-conductive caps 
that cover the entire terminal(s). No commenters addressed this 
proposal; therefore, we are adopting it without change in this final 
rule.

Section 173.166

    Section 173.166 establishes transportation requirements for air bag 
inflators, air bag modules, and seat-belt pretensioners. Currently, 
paragraph (d)(1) excepts from the HMR air bag modules and seat-belt 
pretensioners approved by the Associate Administrator and installed in 
a motor vehicle or a completed motor vehicle component. In the NPRM, we 
proposed to revise paragraph (d)(1) to expand the exception to include 
air bag modules and seat-belt pretensioners installed in other means of 
conveyances, such as boats and aircraft, or their components. We 
received no comments on this proposal; therefore, we are adopting it 
without change in this final rule.

Section 173.187

    Section 173.187 establishes transportation requirements for 
pyrophoric solids, metals, or alloys, not otherwise specified (n.o.s.). 
In the NPRM, we proposed to revise this section for clarity and to 
correct an oversight by adding 4A steel boxes to the list of authorized 
packagings for pyrophoric solids, metals or alloys, n.o.s. We received 
no comments on this proposal; it is adopted without change in this 
final rule.

Section 173.216

    Section 173.216 establishes transportation requirements for blue, 
brown, or white asbestos. Paragraph (c) of this section specifies 
packaging requirements for these materials. In the NPRM, we proposed to 
require bags or other non-rigid packages containing asbestos to be 
transported in rigid outer packages or closed freight containers. No 
commenters addressed this proposal; therefore, it is adopted without 
change in this final rule.

Section 173.220

    Section 173.220 establishes transportation requirements for 
internal combustion engines, self-propelled vehicles, mechanical 
equipment containing internal combustion engines, and battery powered 
vehicles and equipment. For transportation by aircraft, the HMR impose 
a pressure limit of not more than 5% of the maximum allowable working 
pressure in any part of the system between the pressure receptacle and 
the shut off valve of a flammable gas powered vehicle. In the NPRM, we 
proposed to revise paragraph (b)(2)(ii)(B)(3) to specify that the 
pressure limit imposed applies to the entire closed system and that the 
maximum pressure allowed is 290 psig (2000 kPa). Also, consistent with 
the ICAO Technical Instructions, we proposed to revise paragraphs (c) 
and (d) to clarify that batteries may be protected against short 
circuits by the use of non-conductive caps that cover the entire 
terminal(s). We received no comments on these proposals; therefore, we 
are adopting them without change in this final rule.

Section 173.222

    This section establishes requirements for hazardous materials in 
equipment, machinery and apparatus. Because of the addition of Special 
Provision A105 in the HMT, the shipping paper requirements in paragraph 
(d) no longer apply to transportation by aircraft. In the NPRM, we 
proposed to revise paragraph (d) accordingly. No commenters addressed 
this proposal, and it is adopted without change in this final rule.
    A commenter [Laude] requests we remove the phrase ``equipment'' in 
this section. The phrase ``equipment'' is not part of the proper 
shipping name ``Dangerous Goods in Machinery or Dangerous Goods in 
Apparatus'' in the HMT. Therefore, we are editorially revising Sec.  
173.222 to remove the phrase ``equipment'' in the heading and 
regulatory text.

Section 173.224

    Section 173.224 establishes packaging and control and emergency 
temperatures for self-reactive materials. The Self-Reactive Materials 
Table in paragraph (b)(7) of this section specifies self-reactive 
materials authorized for transportation without first being approved 
for transportation by the Associate Administrator for Hazardous 
Materials Safety and requirements for transporting these materials. In 
the NPRM, we proposed to add a new entry to ``Acetone-pyrogallol 
copolymer 2-diazo-1-naphthol-5-sulphonate'' to the Self-Reactive 
Materials Table. We received no comments on this proposal, and are 
adopting it without change in this final rule.

Section 173.230

    In the NPRM, we proposed to add a new packaging section (Sec.  
173.230) for the transportation of ``Fuel cell cartridges containing 
flammable liquids, UN3473,'' including methanol or methanol/water 
solutions. For consistency with the ICAO Technical Instructions, we 
proposed to require fuel cell cartridges containing flammable liquids, 
other than those packaged with equipment, to be packaged in 
specification packagings for all modes of transportation. Fuel cell 
cartridges packaged in or with equipment must be packaged in strong 
outer packagings.
    A commenter [HMT] suggests we add a special provision to the entry 
``Fuel cell cartridges containing flammable liquids'' in the HMT that 
would allow fuel cell cartridges to be considered the inner packaging 
of a combination packaging so that shippers can take advantage of the 
limited quantity provisions for flammable liquids in Sec.  173.150. We 
do not believe that such a clarification is necessary. A fuel cell 
cartridge, shipped under the provisions

[[Page 78607]]

of Sec.  173.150 as a limited quantity, may be considered the inner 
packaging provided all applicable requirements are met. The commenter 
also suggests we change the one liter net capacity limit to allow up to 
one liter volume of the flammable liquid itself. We do not agree. The 
net capacity of a fuel cell cartridge should be the capacity of the 
fuel cell cartridge containing the flammable liquid. This is consistent 
with the requirements for other flammable liquids shipped as a limited 
quantity in inner packagings or articles. Finally, the commenter 
recommends we authorize any rigid outer packaging conforming to the PG 
II performance level. We agree and are amending the requirements in 
paragraph (a)(2) accordingly.

Section 173.301

    On August 29, 2006, the Federal Register published a final rule 
under Docket HM-220F (71 FR 51122)) establishing additional 
requalification requirements for cylinders manufactured of aluminum 
alloy 6351-T6. In Sec.  173.301, we moved a sentence prohibiting the 
use of DOT 3AL cylinders manufactured of aluminum alloy 6351-T6 for 
transporting pyrophoric gases from paragraph (d) to a new paragraph 
(o). We revised the remaining requirement in paragraph (d). However, we 
inadvertently omitted a sentence prohibiting the use of aluminum alloy 
6351-T6 for the manufacture of UN cylinders recently added in paragraph 
(d) under a final rule published June 12, 2006 under Docket HM-220E (71 
FR 33858). In this final rule, we are correcting Sec.  173.301(o) by 
reinserting the language prohibiting the use of UN cylinders 
manufactured of aluminum alloy 6351-T6.

Section 173.306

    This section establishes transportation requirements for limited 
quantities of compressed gases. Paragraph (i) of this section excepts 
aerosols with capacities under 50 mL (1.7 oz) and pressures not 
exceeding 970 kPa (141 psig) at 55 [deg]C (131 [deg]F) from all HMR 
requirements. In the NPRM, we proposed to expand this exception to 
aerosols with capacities of less than 50 mL (1.7 oz) and pressures of 
up to 290 psig (2000 kPa) provided the packagings conform to the 
general packaging requirements of Subpart B of Part 173. The proposed 
amendment is not consistent with provisions of the UN Recommendations 
or the ICAO Technical Instructions, which do not limit the pressure 
within the aerosol or small receptacle. We are not convinced that 
aerosols should be excepted from all regulation when the pressure in 
the container exceeds 290 psig (2000 kPa). Because the exceptions in 
the UN Recommendations and ICAO Technical Instructions include an 
exception from shipping paper, package marking, and labeling 
requirements, a carrier might not be aware of the potential risks 
associated with higher pressure aerosols and small gas receptacles. In 
addition, to avoid confusion and further clarify the intent of this 
exception, in the NPRM we proposed to revise paragraph (i) to specify 
that the 50 mL exception for aerosols does not apply to self-defense 
sprays. It was not our intent to authorize the use of this exception 
for self-defense sprays. We received no comments on this proposal; it 
is adopted in this final rule.

Part 175

Section 175.10

    Currently, safety matches or lighters carried on board an aircraft 
and intended for use by a passenger or crew member are excepted from 
the HMR. Consistent with the ICAO Technical Instructions, in the NPRM 
we proposed to revise paragraph (a)(2) to limit the number of safety 
matches that may be carried on one's person or in carry-on baggage by a 
passenger or crewmember to one packet. We received no comments on this 
issue; therefore, it is adopted without change in this final rule.

Section 175.78

    Section 175.78 establishes requirements for stowing hazardous 
materials on an airplane. In the NPRM, we proposed to paragraph (c)(4) 
to clarify which explosive materials may be stowed together aboard an 
aircraft and to remove existing stowage references for explosive 
materials not authorized for transportation aboard aircraft under any 
circumstances. We received no comments on this issue; therefore, it is 
adopted without change in this final rule.

Part 176

Section 176.76

    Section 176.76 establishes requirements for vessel transportation 
of transport vehicles, freight containers, and portable tanks 
containing hazardous materials. Paragraph (f) includes requirements for 
portable tanks containing flammable liquids or gases. Consistent with 
recent changes to the classification of flammable liquids based on the 
GHS and adopted into the UN Recommendations and discussed elsewhere in 
this preamble, in the NPRM we proposed to revise paragraph (f)(2) to 
specify the new upper limit for a PG III flammable liquid to be 60 
[deg]C (140 [deg]F). We received no comments on this issue; therefore, 
it is adopted without change in this final rule.

Section 176.83

    Section 176.83 establishes segregation requirements for hazardous 
materials transported by vessel. In the NPRM, we proposed to revise 
paragraph (a)(4) to identify materials of different hazard classes that 
do not react dangerously with each other and, therefore, do not need to 
be segregated. No commenters addressed this proposal; it is adopted 
without change in this final rule.

Section 176.84

    Section 176.84 contains additional stowage and segregation 
requirements for hazardous materials on cargo and passenger vessels. 
Consistent with the 2004 Edition of the IMDG Code, incorporating 
Amendment 33-06, in the paragraph (b) Table of provisions, in the NPRM 
we proposed to add new Code ``144'' to the entries ``Plastic molding 
compound in dough, sheet or extruded rope from evolving flammable 
vapor,'' UN3314, and ``Polymeric beads expandable, evolving flammable 
vapor,'' UN2211. New Code ``144'' specifies these materials must be 
mechanically ventilated in accordance with SOLAS Chapter II-2/
Regulation 19 for flammable liquids with a flashpoint below 23 [deg]C 
(73 [deg]F) when stowed under deck. No comments addressed this issue; 
it is adopted without change in this final rule.
    Also, in the NPRM, we proposed to add a new note ``2'' following 
the Table. Note ``2'' provides an exception from the segregation 
requirements for Class 8, PG II and III materials, provided the 
substances do not react dangerously with one another and the quantities 
per package do not exceed 30 L (7.8 gallons) for liquids and 30 kg (66 
lbs.) for solids. We also proposed to revise Codes ``26,'' ``27,'' 
``52,'' and ``53'' to add the new Note ``2.''
    One commenter [VOHMA] supports the proposal to add a new Note 
``2,'' but suggests the following provision be added: ``The transport 
document must include the statement required by Sec.  172.203(i)(5) and 
a copy of the test report that verifies that the substances do not 
react dangerously with each other shall be provided if requested by the 
competent authority.'' The commenter also recommends an additional 
shipping paper requirement under Sec.  172.203 to indicate the 
utilization of this provision. The commenter bases its request on a 
need for consistency with the IMDG Code, and the need for verification 
to the carrier that the substances have been

[[Page 78608]]

tested and do not react dangerously with each other.
    We acknowledge the commenter's recommendation that new Note ``2'' 
may require an accompanying statement on a transport document, such as 
a shipping paper, in order to adequately notify carriers of the use of 
this provision. We also acknowledge the commenter's suggestion that 
supporting documentation, such as a test report, should accompany 
shipments of these hazardous materials. Because these additional 
requirements were not proposed in the NPRM, they are beyond the scope 
of this rulemaking. However, we agree that carriers may need some 
notification of the use of this provision and will consider the issue 
in a future rulemaking.
    In this final rule, we are adopting the proposal to add new Note 
``2'' to the Segregation Table, and to revise Codes ``26,'' ``27,'' 
``52,'' and ``53'' by adding the new Note ``2,'' as proposed in the 
NPRM. In addition, we are also adopting the proposal to add Code 
``144'' to the entries ``Plastic molding compound in dough, sheet or 
extruded rope from evolving flammable vapor,'' UN3314, and ``Polymeric 
beads expandable, evolving flammable vapor,'' UN2211, to specify these 
materials must be mechanically ventilated in accordance with SOLAS 
regulation II-2/19 (IBR; see Sec.  171.7 of this subchapter) for 
flammable liquids with a flashpoint below 23 [deg]C (73 [deg] F) when 
stowed under deck. Finally, in paragraph (b), we are revising 
Provisions ``22,'' ``23,'' and ``109'' to reflect the new upper 
flammability limit for flammable liquids. Also see Sec. Sec.  173.35, 
173.120, 173.121 and Appendix H to Part 173 preamble text.

Part 178

Section 178.274

    Section 178.274 establishes design, manufacturing, and test 
requirements for UN portable tanks. Currently, a prototype UN portable 
tank must be shown to be capable of absorbing the forces resulting from 
an impact not less than four times the maximum permissible gross weight 
of the fully loaded portable tank at a duration that is typical of the 
mechanical shocks experienced in rail transportation. Several standards 
describing methods acceptable for performing the impact test were 
previously listed in the UN Recommendations (6.7.3.15). The Fourth 
revised edition of the UN Manual of Tests and Criteria includes a 
dynamic longitudinal impact test for portable tanks. All procedures, 
test requirements, processing and analysis of data are found in Section 
41 of Addendum 2 to the UN Manual of Tests and Criteria.
    Consistent with the UN Recommendations, in the NPRM we proposed to 
revise paragraph (j)(6) to require each UN portable tank design type be 
subjected to a dynamic longitudinal impact test to prove the ability of 
the portable tank to withstand the effects of a longitudinal impact. 
The NPRM proposed an effective for the new requirement of January 1, 
2008, and further proposed that UN portable tanks impact-tested prior 
to January 1, 2008, based on the criteria in effect on October 1, 2005, 
need not be retested. We received no comments on this proposal; we are 
adopting it without change in this final rule.

Section 178.602

    Section 178.602 establishes requirements for the preparation of 
packagings for testing to ensure that the packaging conforms to the 
design requirements of the applicable specification. Currently, for the 
preparation of bags for the drop and stacking tests, paragraph (b) 
requires bags to be filled to the maximum mass at which they may be 
used. In the NPRM, we proposed to revise paragraph (b) to clarify that 
the preparation of bags for the drop and stacking tests only applies to 
bags containing solids. No commenters addressed this proposal; it is 
adopted without change in this final rule.

Section 178.810

    Section 178.810 establishes requirements for performing the drop 
test for IBCs. In the NPRM, we proposed to revise paragraph (b)(1) to 
clarify that metal, rigid plastic, and composite IBCs must be filled to 
not less than 95% of their maximum capacity when conducting drop tests 
for solids, and not less than 98% of their maximum capacity for 
liquids. Similarly, in paragraph (b)(2), we proposed to require 
fiberboard and wooden IBCs to be filled with a solid material to not 
less than 95% of their maximum capacity. Also, we proposed to add a new 
paragraph (b)(3) to require filling flexible IBCs to the maximum 
permissible gross mass and even distribution of the contents. No 
commenters addressed these proposals; they are adopted without change 
in this final rule.

Part 180

Section 180.213

    On August 29, 2006 the Federal Register published a final rule 
under Docket HM-220F (71 FR 51122) establishing additional 
requalification requirements for cylinders manufactured of aluminum 
alloy 6351-T6. In the amendatory language, we inadvertently revised 
paragraph (d) rather than the paragraph (d) introductory text. In this 
final rule, we are revising paragraph (d) to correct this error.

Section 180.352

    Section 180.352 establishes requirements for retesting and 
inspection of IBCs to ensure that they continue to conform to the 
applicable specification. In the NPRM, we proposed to revise paragraph 
(b) to specify that each IBC intended to contain solids that are loaded 
or discharged under pressure or intended to contain liquids must be 
tested in accordance with the leakproofness test prescribed in Sec.  
178.813 prior to its first use in transportation. For this test, the 
IBC is not required to have its closures fitted. These proposals 
incorporate clarifications adopted in the Fourteenth revised edition of 
the UN Recommendations. We received no comments on these proposals and 
are adopting them without change in this final rule.

IV. 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 material 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 earlier in this preamble, the final rule amends the HMR to 
more fully align them with the biennial updates of the UN 
Recommendations, the IMDG Code and the ICAO Technical Instructions; 
this will facilitate the transport of hazardous materials in 
international commerce.
    Harmonization serves to facilitate international transportation; at 
the same time, harmonization ensures the safety of people, property, 
and the environment by reducing the potential for confusion and 
misunderstanding that could result if shippers and

[[Page 78609]]

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 discussed in detail earlier in this 
preamble, there are several instances where we elected not to adopt a 
specific provision of the UN Recommendations, the IMDG Code or the ICAO 
Technical Instructions. 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 final 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 earlier in this preamble, the rule incorporates changes into 
the HMR based on the Fourteenth revised edition of the UN 
Recommendations, Amendment 33 to the IMDG Code, and the 2007-2008 ICAO 
Technical Instructions, which become effective January 1, 2007. 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, battery manufacturers, and 
radiopharmaceutical companies. Benefits resulting from 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 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 are authorizing a delayed effective date and a one-year 
transition period for the majority of amendments in this final rule; we 
are authorizing extended transition periods for certain amendments. The 
transition periods allow for training of employees and 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. The costs are the result of reprogramming shipping paper 
computer programs, replacement of pre-printed forms for firms that do 
not use automated systems, and changes to package markings and labels. 
Initial start-up and inventory costs result from these changes; 
however, the costs will be 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 impose any regulation that has substantial direct effects on the 
States, the relationship between the national government and the 
States, or the distribution of power and responsibilities among the 
various levels of government. Therefore, the consultation and funding 
requirements of Executive Order 13132 do not apply.
    The Federal hazardous material transportation law, 49 U.S.C. 5101-
5128, contains an express preemption provision (49 U.S.C. 5125(b)) that 
preempts State, local, and Indian tribe requirements on certain covered 
subjects. Covered subjects are:
    (1) The designation, description, and classification of hazardous 
material;
    (2) The packing, repacking, handling, labeling, marking, and 
placarding of hazardous material;
    (3) The preparation, execution, and use of shipping documents 
related to hazardous 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), 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, 2007. If the changes in this final rule are not 
adopted in 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 rulemaking are intended to avoid this 
result. Federal hazardous materials transportation law provides at 
section 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 
may not be earlier than the 90th day following the date of issuance of 
the final rule and not later than two years after the date of issuance. 
The effective date of Federal preemption is March 29, 2007.

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 and does not impose substantial 
direct compliance costs, 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

[[Page 78610]]

consistency with international standards. This final rule applies to 
offerors and carriers of hazardous materials, some of whom are small 
entities, such as chemical users and suppliers, packaging 
manufacturers, distributors, and battery manufacturers. As discussed 
above, under Executive Order 12866, the majority of amendments in this 
final rule 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 the requirements in this final 
rule will not have a significant economic impact on a substantial 
number of small entities.
    This final rule has been developed in accordance with Executive 
Order 13272 (``Proper Consideration of Small Entities in Agency 
Rulemaking'') and DOT's procedures and policies to promote compliance 
with the Regulatory Flexibility Act to ensure that potential impacts of 
draft rules on small entities are properly considered.

F. Paperwork Reduction Act

    Under the Paperwork Reduction Act of 1995, no person is required to 
respond to a collection of information unless it displays a valid 
Office of Management and Budget (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 collection and recordkeeping 
requests. PHMSA currently has two approved information collections 
affecting this final rule: OMB Control Number 2137-0557, ``Approvals 
for Hazardous Materials'' with 25,605 burden hours and $562,837.40 
burden costs; and OMB Control Number 2137-0613, ``Subsidiary Hazard 
Class & Number/Type of Packagings'' with 63,309 burden hours and 
$216,705 burden costs.
    There are minor editorial changes under this rule. However, there 
is no net increase in burden for OMB Control Number 2137-0557 or OMB 
Control Number 2137-0613. We estimate the total information collection 
and recordkeeping burden as follows:
``Approvals for Hazardous Materials'' OMB Number 2137-0557:
    Total Annual Number of Respondents: 3,523.
    Total Annual Responses: 3,874.8.
    Total Annual Burden Hours: 25,605.
    Total Annual Burden Cost: $562,837.40.
``Subsidiary Hazard Class & Number/Type of Packagings'' OMB Number 
2137-0613:
    Total Annual Number of Respondents: 250,000.
    Total Annual Responses: 6,337,500.
    Total Annual Burden Hours: 17,604.
    Total Annual Burden Cost: $216,705.
    Total First Year Burden Hours: 45,705.
    Total First Year Burden Cost: $1,115,992.
    Requests for a copy of this information collection should be 
directed to Deborah Boothe or T. Glenn Foster, Office of Hazardous 
Materials Standards (PHH-10), Pipeline and Hazardous Materials Safety 
Administration, Room 8422, 400 Seventh Street, SW., Washington, DC 
20590-0001, telephone (202) 366-8553.

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 
$120.7 million or more to either State, local or tribal governments, in 
the aggregate, or to the private sector, and is the least burdensome 
alternative that achieves the objective of the rule.

I. Environmental Assessment

    The National Environmental Policy Act of 1969 (NEPA) requires 
Federal agencies to consider the consequences of major Federal actions 
and prepare a detailed statement on actions significantly affecting the 
quality of the human environment. We developed an assessment to 
determine the effects of these revisions on the environment and whether 
a more comprehensive environmental impact statement may be required. 
Consistency in the regulations for the transportation of hazardous 
materials aids in shipper understanding of the requirements and permits 
shippers to more easily comply with safety regulations and avoid the 
potential for environmental damage or contamination. Our findings 
conclude that there are no significant environmental impacts associated 
with this final rule. For interested parties, an Environmental 
Assessment is available in the public docket.

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 (Volume 65, Number 70;

Sec.  171.14  Transitional provisions for implementing certain 
requirements.

* * * * *
    (b) [Reserved]
* * * * *
    (d) A final rule published in the Federal Register on December 29, 
2006, effective January 1, 2007, resulted in revisions to this 
subchapter. During the transition period, until January 1, 2008, as 
provided in paragraph (d)(1) of this section, a person may elect to 
comply with either the applicable requirements of this subchapter in 
effect on December 31, 2006, or the requirements published in the 
December 29, 2006 final rule.
    (1) Transition dates. The effective date of the final rule 
published on December 29, 2006 is January 1, 2007. A delayed compliance 
date of January 1, 2008, is authorized. Unless otherwise specified, on 
and after January 1, 2008, all applicable regulatory requirements 
adopted in the final rule in effect on January 1, 2007, must be met.
    (2) Intermixing old and new requirements. Marking, labeling, 
placarding, and shipping paper descriptions must conform to either the 
old requirements of this subchapter in effect on December 31, 2006, or 
the new requirements of this subchapter in the final rule without 
intermixing communication elements, except that intermixing is 
permitted during the applicable transition period for packaging, hazard 
communication and handling provisions, as follows:
    (i) If either shipping names or identification numbers are 
identical, a shipping paper may display the old shipping description 
even if the package is marked and labeled under the new shipping 
description;
    (ii) If either shipping names or identification numbers are 
identical, a shipping paper may display the new shipping description; 
and
    (iii) Either old or new placards may be used regardless of whether 
old or new

[[Page 78612]]

shipping descriptions, labels, and package markings are used.
* * * * *
    (e) The shipping description sequences in effect on December 31, 
2006, may be used until January 1, 2013.
    (f) Except for transportation by highway, a Division 5.2 label and 
a Division 5.2 placard conforming to the specifications in Sec. Sec.  
172.427 and 172.552, respectively, of this subchapter in effect on 
December 31, 2006, may be used until January 1, 2011. For 
transportation by highway, a Division 5.2 placard conforming to the 
specifications in Sec.  172.552 of this subchapter in effect on 
December 31, 2006 may be used until January 1, 2014.
    (g) The Class 3 and Division 6.1 classification criteria and 
packing group assignments in effect on December 31, 2006, may be used

the Convention for Safe Containers (CSC) (see 49 CFR 450.3(a)(2)) must 
be subjected to the dynamic longitudinal impact test prescribed in Part 
IV, Section 40 of the UN Manual of Tests and Criteria (see IBR, Sec.  
171.7 of this subchapter). A UN portable tank design type impact-tested 
prior to January 1, 2008, in accordance with the requirements of this 
section in effect on October 1, 2005, need not be retested. UN portable 
tanks used for the dedicated transportation of ``Helium, refrigerated 
liquid,'' UN1963, and ``Hydrogen, refrigerated liquid,'' UN1966, that 
are marked ``NOT FOR RAIL TRANSPORT'' in letters of a minimum height of 
10 cm (4 inches) on at least two sides of the portable tank are 
excepted from the dynamic longitudinal impact test.

Sec.  178.810  Drop test.

* * * * *
    (b) Special preparation for the drop test. (1) Metal, rigid 
plastic, and composite IBCs intended to contain solids must be filled 
to not less than 95 percent of their maximum capacity, or if intended 
to contain liquids, to not less than 98 percent of their maximum 
capacity. Pressure relief devices must be removed and their apertures 
plugged or rendered inoperative.
    (2) Fiberboard and wooden IBCs must be filled with a solid material 
to not less than 95 percent of their maximum capacity; the contents 
must be evenly distributed.
    (3) Flexible IBCs must be filled to the maximum permissible gross 
mass; the contents must be evenly distributed.
    (4) Rigid plastic IBCs and composite IBCs with plastic inner 
receptacles must be conditioned for testing by reducing the temperature 
of the packaging and its contents to -18 [deg]C (0 [deg]F) or lower. 
Test liquids must be kept in the liquid state, if necessary, by the 
addition of anti-freeze. Water/anti-freeze solutions with a minimum 
specific gravity of 0.95 for testing at -18 [deg]C (0 [deg]F) or lower 
are considered acceptable test liquids, and may be considered 
equivalent to water for test purposes. IBCs conditioned in this way are 
not required to be conditioned in accordance with Sec.  178.802.

Sec.  180.213  Requalification markings.

* * * * *
    (d) Requalification markings. Each cylinder successfully passing 
requalification must be marked with the RIN set in a square pattern, 
between the month and year of the requalification date. The first 
character of the RIN must appear in the upper left corner of the square 
pattern; the second in the upper right; the third in the lower right; 
and the fourth in the lower left. Example: A cylinder requalified in 
September 2006, and approved by a person who has been issued RIN 
``A123'', would be marked plainly and permanently into the metal of the 
cylinder in accordance with location requirements of the cylinder 
specification or on a metal plate permanently secured to the cylinder 
in accordance with paragraph (b) of this section. An example of the 
markings prescribed in this paragraph (d) is as follows:
[GRAPHIC] [TIFF OMITTED] TR29DE06.012

Where:

``9'' is the month of requalification
``A123'' is the RIN
``06'' is the year of requalification, and
``X'' represents the symbols described in paragraphs (f)(2) through 
(f)(8) of this section.

    (1) Upon written request, variation from the marking requirement 
may be approved by the Associate Administrator.
    (2) Exception. A cylinder subject to the requirements of Sec.

Sec.  180.352  Requirements for retest and inspection of IBCs.

* * * * *
    (b) Test and inspections for metal, rigid plastic, and composite 
IBCs. Each IBC is subject to the following test and inspections:
    (1) Each IBC intended to contain solids that are loaded or 
discharged under pressure or intended to contain liquids must be tested 
in accordance with the leakproofness test prescribed in Sec.  178.813 
of this subchapter prior to its first use in transportation and every 
2.5 years thereafter, starting from the date of manufacture or the date 
of a repair conforming to paragraph (d)(1) of this section. For this 
test, the IBC is not required to have its closures fitted.
* * * * *
    (g) Record retention. (1) The owner or lessee of the IBC must keep 
records of periodic retests, initial and periodic inspections, and 
tests performed on the IBC if it has been repaired or remanufactured.
    (2) Records must include design types and packaging specifications, 
test and inspection dates, name and address of test and inspection 
facilities, names or name of any persons conducting test or 
inspections, and test or inspection specifics and results.
    (3) Records must be kept for each packaging at each location where 
periodic tests are conducted, until such tests are successfully 
performed again or for at least 2.5 years from the date of the last 
test. These records must be made available for inspection by a 
representative of the Department on request.
