I. Background

    On December 21, 1990, the Research and Special Programs 
Administration (RSPA), the predecessor agency to the Pipeline and 
Hazardous Materials Safety Administration (PHMSA, we) published a final 
rule (Docket HM-181; 55 FR 52402) based on the UN Recommendations on 
the Transport of Dangerous Goods, to comprehensively revise the 
Hazardous Materials Regulations (HMR), 49 CFR parts 171 to 180, for 
harmonization with the international standards. Since publication of 
the 1990 final rule, we have issued six additional international 
harmonization final rules, (Dockets HM-215A, 59 FR 67390; HM-215B, 62 
FR 24690; HM-215C, 64 FR 10742; HM-215D, 66 FR 33316; HM-215E, 68 FR 
44992; and HM-215G, 69 FR 76044). The rules provided additional 
harmonization with international transportation requirements by more 
fully aligning the HMR with the corresponding biennial updates of the 
UN Recommendations, the IMDG Code and the ICAO Technical Instructions.
    The UN Recommendations are not regulations, but rather are 
recommendations issued by the UN Committee of Experts on the Transport 
of Dangerous Goods (TDG) and on the Globally Harmonized System of 
Classification and Labelling of Chemicals (GHS). These recommendations 
are amended and updated biennially by the UN Committee of Experts. They 
serve as the basis for national, regional, and international modal 
regulations, including the International Maritime Organization's 
International Maritime Dangerous Goods Code (IMDG Code), and the 
International Civil Aviation Organization's Technical Instructions for 
the Transport of Dangerous Goods by Air (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 serves to facilitate 
international transportation, while maintaining appropriate protection 
of people, property, and the environment. Although the intent of the 
harmonization rulemakings is to align the HMR with international 
standards, 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. In our efforts to continue 
aligning the HMR with international requirements, in this NPRM, we are 
proposing to incorporate 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. We are also addressing petitions for 
rulemaking concerning harmonization with international standards and 
additional measures to facilitate international transportation.

[[Page 51895]]

II. Sunset Provision

    To assure the HMR account for new technologies and updated business 
practices, PHMSA is considering whether certain requirements proposed 
in this NPRM should be afforded a ``sunset'' provision. If we adopt 
such a provision, certain amendments adopted through this rulemaking 
would expire after a fixed amount of time (e.g., 10 years) from the 
publication date of the final rule.
    Harmonizing the HMR with international transportation requirements 
facilitates the transportation of hazardous materials in international 
commerce by eliminating the need for shippers and carriers to comply 
with two different sets of regulations. Certain standards that we are 
proposing to adopt by reference likely will be updated periodically in 
response to changes in international standards or may be replaced by 
other more relevant or technically superior standards. Future changes 
to these standards would have to consider whether to retain or extend 
the sunset date. If we choose to do nothing, a sunset provision would 
mean the HMR would revert to the language and requirements in effect 
before the issuance of the final rule. We are requesting comments on 
whether certain amendments should be tied to a sunset provision.

III. Overview of Proposed Changes in This NPRM

    In this NPRM, we are proposing 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). Currently, the HMR permit the shipping paper 
description sequence to start with either the identification number or 
the proper shipping name.
     Requirement to indicate the net quantity of hazardous 
material per package on the shipping paper if transportation is by 
aircraft. The HMR do not currently require this information on a 
shipping paper.
     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 
assignment 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.

IV. Overview of International Standards Not Being Considered for 
Adoption in This NPRM

    This NPRM proposes 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 proposing to 
adopt 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).
    If we have inadvertently omitted an amendment in this NPRM, we will 
attempt to include the omission in the final rule. However, our ability 
to make changes in a final rule is limited by requirements of the 
Administrative Procedure Act. In some instances, we can adopt a 
provision inadvertently omitted in the NPRM if it is clearly within the 
scope of changes proposed in the notice, does not require substantive 
changes from the international standard on which it is based, and 
imposes minimal or no cost impacts on persons subject to the 
requirement. Otherwise, in order to provide opportunity for notice and 
comment, the change must be proposed in an NPRM.
    One of the goals of this rulemaking is to continue to maintain 
consistency between the HMR and the international requirements. We are 
not striving to make the HMR identical to the international regulations 
but rather to remove or avoid potential barriers to international 
transportation.
    Below is a listing of those significant amendments to the 
international regulations that we are not proposing to adopt in this 
NPRM with a brief explanation of why the amendment was not included:
     Environmentally hazardous substances. The UN 
Recommendations have not yet been adopted by ICAO and IMO. These 
changes will be considered 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. We are analyzing the 
differences and, based on our conclusions, will consider a separate 
rulemaking to address this issue.
     Requirements for radioactive materials. We are not 
proposing to adopt 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 
proposing to adopt 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 proposing to adopt 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 
proposing to adopt the packaging provisions for the transport of 
``Hydrogen in a metal hydride storage system,'' (UN3468), as adopted by 
ICAO. Currently, the HMR allow transportation of these storage systems 
by motor vehicle and rail under the terms of an exemption and by motor 
vehicle, rail, cargo vessel and cargo aircraft with approval of the 
Associate Administrator. These issues will be

[[Page 51896]]

considered in a separate rulemaking proceeding.
     Marking of Limited Quantity shipments. The ICAO Technical 
Instructions adopted a marking requirement for packages containing a 
limited quantity of hazardous material that 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.

V. Section-by-Section Review

Part 171

Section 171.7
    Section 171.7 lists the standards incorporated by reference into 
the HMR. We propose to update 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.
    The standards would be updated as follows:
     The ICAO Technical Instructions, 2007-2008 Edition.
     The IMDG Code, Amendment 33.
     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. Paragraph (b) lists transitional 
provisions related to revised placarding requirements. In this NPRM, we 
propose to remove paragraph (b) because the transitional period has 
expired.
    Paragraph (d) of this section specifies transition provisions for 
previously adopted amendments intended to harmonize the HMR with 
international standards. We are proposing revisions to this paragraph 
to provide specific transitional provisions for certain of the 
amendments proposed in this NPRM. We are proposing an effective date of 
January 1, 2007, and a mandatory compliance date of January 1, 2008. We 
propose to permit voluntary compliance as of January 1, 2007, to 
correspond with the effective implementation dates of the 2007-2008 
ICAO Technical Instructions and Amendment 33 of the IMDG Code. This 
authorization would allow 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 transition 
provision. In this NPRM, we propose to replace the outdated transition 
provision with a new paragraph (e) that would permit use for domestic 
shipments of the shipping description sequences in effect on December 
31, 2006, until January 1, 2009. 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 propose to revise 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, 2011. 
See the Sec. Sec.  172.407 and 172.427 preamble discussions for a 
complete explanation of this issue.
    In new paragraph (g), we are proposing to allow 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, which contains the hazard class 
or division for each specific material listed in the HMT. Paragraph 
(d)(4) addresses entries classed as combustible liquids. We are 
proposing 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 GHS and 
adoption into the UN Recommendations.
    The Sec.  172.101 Hazardous Materials Table (HMT): In the Sec.  
172.101 Hazardous Materials Table (HMT), we are proposing to make 
various amendments. Readers should review all changes for a complete 
understanding of the proposed Table amendments. For purposes of the 
Government Printing Office's typesetting procedures, proposed changes 
to the HMT will appear under three sections of the Table, ``remove,'' 
``add'' and ``revise.'' Certain entries in the HMT, such as those with 
proposed revisions to the proper shipping names, will appear as a 
``remove'' and ``add.'' Under this NPRM, the proposed amendments to the 
HMT for the purpose of harmonizing with international standards, unless 
otherwise stated, include, but are not limited to the following:
    1. We propose to correct 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:

                                     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 proposing to revise 
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.

                                     10 percent but not more than 35
                                     percent ammonia.

UN3073............................  Vinylpyridines, stabilized.
 

    3. The entry ``Aerosols, non-flammable, (each not exceeding 1 L 
capacity),'' UN1950, would be revised by adding vessel storage location 
code ``A'' in Column (10A). This code was inadvertently removed in a 
final rule published under Docket HM-189Y (70 FR 56084; September 23, 
2005).
    4. The entry ``Antimony trichloride, solid,'' UN1733, PG II, would 
be 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, would be 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, would be 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, would be revised 
by removing the reference to Sec.  173.153 ``Exceptions for Division 
6.1 (poisonous materials)'' in Column (8A).
    8. In accordance with changes in the Fourteenth revised edition of 
the UN Recommendations, we propose to remove the following entries:

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

    9. The entry, ``Charges, shaped, flexible, linear,'' UN0288, would 
be 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, 
would be 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, would be 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, would be 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,

Sec.  173.153 ``Exceptions for Division 6.1 (poisonous materials)'' in 
Column (8A).
    14. The entry ``Chromium trioxide, anhydrous,'' UN1463, Column (6) 
would be revised by adding the Division 6.1 subsidiary hazard labeling 
requirement.
    15. The entry ``Compressed gas, n.o.s.,'' UN1956, would be 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, would be revised by 
removing Special provision 101, which requires the name of the 
particular substance or article to be specified. In addition, the 
letter ``G'' would be 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, would be revised by 
removing Special provision 101, which requires the name of the 
particular substance or article to be specified. In addition, the 
letter ``G'' would be 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, would be 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,'' UN1143, would be revised to read ``Crotonaldehyde or 
Crotonaldehyde, stabilized'' and to add proposed 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, would be corrected to read ``Crotonic acid, liquid'' 
and the Identification Number would be 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, would be 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,'' UN 
3363, would be revised by adding quantity limits for transportation by 
aircraft. The quantity limits will be specified in a new Special 
provision A105.
    23. The entry ``Ethyltrichlorosilane,'' UN1196, PG II, would be 
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, would be revised to read 
``Formic acid with more than 85% acid by mass'' and the Class 3 
subsidiary hazard would be 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, would be added.
    26. A new entry, ``Formic acid with not less than 5% but less than 
10% acid by mass,'' UN3412, would be added.
    27. A new entry, ``Fuel cell cartridges containing flammable 
liquids,'' UN3473, would be added.
    28. The entry ``Hydrazine aqueous solutions, with more than 37% 
hydrazine, by mass'' UN2030, PG I, would be 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,''

[[Page 51899]]

UN3468, would be 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, would be 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, would be 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, would be 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, would be 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, would be 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 proposed addition of Special 
provision T9 would remove this requirement.
    34. For the entry ``Hydrogendifluorides, n.o.s.,'' UN1740, PG II 
and III, the proper shipping name would be revised by 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, would be added.
    36. The entry ``Hydroquinone, solid,'' UN2662, would be removed.
    37. The entry ``Hydroquinone solution,'' UN3435, would be removed.
    38. The entry ``Hypochlorite solutions,'' UN1791, PG II, would be 
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) would be 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) would be revised to read 
25 kg and 100 kg, respectively.
    41. The entry ``Methylphenyldichlorosilane,'' UN2437, PG II, would 
be 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, would be 
corrected by removing the subsidiary hazard label requirement in Column 
(6).
    43. The entry ``Organometallic substance, solid, pyrophoric,'' 
UN3391, PG I, would be 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, would be 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, would be 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, would be added.
    47. The entry ``Paint including paint, lacquer, enamel, stain, 
shellac solutions, varnish, polish, liquid filler and liquid lacquer 
base,'' UN1263, would be 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 
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.
--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 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 
Specification portable tank, a portable tank having a minimum test 
pressure of 1.5 bar (150.0 kPa) may be used provided the calculated 
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.

    48. The entry ``Paint or Paint related materials,'' UN3066, would 
be 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 
Specification portable tank, a portable tank having a minimum test 
pressure of 1.5 bar (150.0 kPa) may be used provided the calculated 
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.

    49. A new entry, ``Paint related material, corrosive, flammable 
(including paint thinning or reducing compound),'' UN3470, PG II, would 
be added.
    50. A new entry, ``Paint related material, flammable, corrosive 
(including paint thinning or reducing compound),'' UN3469, PG I, II, 
and III would be added.

adding the following Special provisions to the PG I, II, and III 
entries, respectively:


[[Page 51900]]


--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 
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.
--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 
Specification portable tank, a portable tank having a minimum test 
pressure of 1.5 bar (150.0 kPa) may be used provided the calculated 
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, would be 
revised by removing vessel stowage location A and adding location E in 
Column (10A), and by adding Vessel Stowage provisions 19, 25 and 
proposed new Vessel Stowage provision 144 in Column (10B).
    53. The entry ``Polymeric beads, expandable, evolving flammable 
vapor, UN2211, PG III, would be revised by removing stowage location A 
and adding location E in Column (10A), and by adding Vessel Stowage 
provisions 19, 25 and proposed new Vessel Stowage provision 144 in 
Column (10B).
    54. For the entry ``Propionic acid,'' UN1848, the proper shipping 
name would be 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, would be added.
    56. The entry ``Rare gases mixtures, compressed,'' UN1979, would be 
removed.
    57. The entry ``Rare gases and oxygen mixtures, compressed,'' 
UN1980, would be removed.
    58. The entry ``Rare gases and nitrogen mixtures, compressed,'' 
UN1981, would be removed.
    59. The proper shipping name ``Regulated medical waste,'' UN3291, 
would be 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, would be added in its place.
    60. For the international entry for ``Sulfur,'' UN1350, the 
quantity limitations in Columns (9A) and (9B) would be revised to read 
25 kg and 100 kg, respectively.
    61. The entry ``Trimethylchlorosilane,'' UN1298, PG II, would be 
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 proposing to add the 
designation ``PP'' to indicate that copper chloride is a severe marine 
pollutant. We are also proposing to correct 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 under Docket HM-
215G (69 FR 76044; December 20, 2004) and removal of the entry ``1,2-
Dichlorobenzene'' was overlooked in a final rule published under Docket 
HM-215D (66 FR 33316; June 21, 2001).
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. For 
consistency with international standards, we propose to amend 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 propose 
to revise 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 would be revised to specify 
that, in addition to sealed packets, articles containing less than 10 
mL of a Class 3 Packing Group II or III liquid absorbed into a solid 
material would be excepted from the HMR provided there is no free 
liquid in the packet.
     Special provision 77 applies to use of Division 5.1 
subsidiary risk label. We propose to revise this special provision for 
consistency with the wording in the UN Recommendations. As proposed, 
Special provision 77 would no longer apply only to ``domestic 
transportation.'' Further, we propose to clarify that a Division 5.1 
label is required if other oxidizing gases are present. Also, the 
provision would be applied 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 NPRM, we are proposing to remove the entry for 
``Carbon dioxide and oxygen mixtures, compressed,'' which is consistent 
with its removal from the UN Recommendations.
     Special provision 146 would be amended to authorize the 
domestic classification of a material as environmentally hazardous if 
it is designated as such by foreign competent authorities. The 
provision as currently worded may be interpreted to only allow such 
classification for international shipments. Due to current differences 
in criteria for the classification of environmentally hazardous 
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.
     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 would be 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 
propose to revise Special provision 166 to remove the authorization for 
``hydrated'' non-friable tablet forms of calcium hypochlorite to be 
transported as a PG III material.

[[Page 51901]]

     A new Special provision 175 would be added to require 
stabilization for certain substances when transported in concentrations 
of not more than 99%.
     Special provision 101 would be removed. This special 
provision requires 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 becomes obsolete.
     A new Special provision A105 would be added to specify the 
quantity of hazardous materials allowed in equipment or apparatus.
Section 172.202
    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 according to 
the ICAO Technical Instructions and the IMDG Code. In this NPRM, we 
propose to adopt the alternative shipping description sequence. We are 
also proposing a 2-year transition period to allow offerors sufficient 
time to convert to the new shipping description sequence. Readers are 
invited to comment on this proposal, especially on the length of the 
transition period.
    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, we are proposing 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

    Different size packages containing different quantities of the same 
hazardous material must be clearly identified. For example:

UN 1263, Paint, 3, PG II, 5 fiberboard boxes x 5 L, 6 fiberboard boxes 
x 10 L
    Where the letter ``G'' follows the quantity in Column (9A) or (9B), 
the gross mass must be indicated, rather than the net quantity.
    Also, we are proposing 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.
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. In this NPRM, 
we propose to revise paragraph (a) to require orientation markings on 
single packagings fitted with vents and on open cryogenic receptacles 
intended for the transport of refrigerated liquefied gases. Also, we 
propose 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 to 
require the color of the arrows to be either black or red on a suitable 
contrasting background. Currently, the HMR do not specify either size 
or color requirements. Finally, we are proposing to add a new paragraph 
(c)(7) to except Class 7 radioactive materials in type A, IP-2, IP-3, 
B(U), B(M) or C packages from the orientation marking requirement.
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 are proposing to 
revise the ORGANIC PEROXIDE label. The new label will reflect the fact 
that organic peroxides are highly flammable and will enable transport 
workers to readily distinguish peroxides from oxidizers with which they 
are generally not compatible. We also propose to allow labels meeting 
the specifications in effect on December 31, 2006, to continue to be 
displayed until January 1, 2011 (see Sec.  171.14). Adoption of the 
redesigned label will 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.
Section 172.552
    Section 172.552 establishes specific requirements for the ORGANIC 
PEROXIDE placard. In accordance with the UN Recommendations, in 
paragraph (b), we are proposing to revise the ORGANIC PEROXIDE placard. 
The new placard will reflect the fact that organic peroxides are highly 
flammable and will enable transport workers to readily distinguish 
peroxides from oxidizers with which they are generally not compatible. 
We also propose to allow placards meeting the specifications in effect 
on December 31, 2006, to continue to be displayed until January 1, 2011 
(see Sec.  171.14).

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 fumigant transport vehicle or freight 
container was ventilated to remove harmful concentration of fumigant 
gas.

[[Page 51902]]

To minimize the possibility of an individual entering a fumigated 
transport vehicle or freight container prematurely, we are proposing to 
add the date of ventilation on the FUMIGANT marking. We are also 
proposing to revise the specifications for the FUMIGANT marking to 
allow either red or black marking on a white background. Finally, we 
are proposing to revise the section for clarity.
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. We are proposing revisions in 
all of these sections to revise the upper limit for a PG III flammable 
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 GHS and adoption into the UN Recommendations. 
PHMSA is also proposing a five-year transition period.
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 propose 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).
    Currently, paragraph (k)(5) of this section requires aerosols 
containing Class 8, PG III materials to be assigned a Class 8 
subsidiary hazard. We are proposing 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.
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. We are proposing 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.
Section 173.133
    Section 173.133 establishes criteria for assignment of packing 
groups to poisonous (Division 6.1) materials. We are proposing 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 will be regulated as Division 6.1, 
Packing Group III; some materials currently regulated as Division 6.1, 
Packing Group I or II will be assigned to a different packing group; 
and some materials that were previously regulated as Division 6.1, 
Packing Group III will not be subject to regulation under the HMR. 
PHMSA is proposing a five year transition period.
    The effect of these changes to packing group assignments for 
Division 6.1 materials is summarized as follows:

------------------------------------------------------------------------
                                     Current PG          Proposed PG
      Material properties            assignment           assignment
------------------------------------------------------------------------
Oral LD50 > 200, <= 300         Not regulated......  III.

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

Sections 173.134 and 173.197
    These sections are revised by replacing the wording ``Regulated 
medical waste'' with the wording ``Regulated medical waste or clinical 
waste or (bio) medical waste.''
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 that the Class 8 definition 
should apply equally to liquids and to solids offered for 
transportation or transported in a liquid state. Therefore, we are 
proposing to revise the definition of a ``corrosive material'' in 
paragraph (a), to include a solid material that is offered for 
transportation or transported as a liquid and has a severe corrosion 
rate on steel or aluminium.
    Also, we are proposing to remove 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 under Docket HM-215G (69 
FR 76155; December 20, 2004), 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 this NPRM, we 
are proposing 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.
Section 173.159
    Section 173.159 establishes transportation requirements for wet 
electric storage batteries. In accordance with the ICAO Technical 
Instructions, we are proposing 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).

[[Page 51903]]

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. We propose to 
revise paragraph (d)(1) to expand the exception to include air bag 
modules and seat-belt pretensioners installed in other means of 
conveyance, such as boats and aircraft, or their components.
Section 173.187
    Section 173.187 establishes transportation requirements for 
pyrophoric solids, metals, or alloys, not otherwise specified (n.o.s.). 
We propose 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.
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 paragraph (c), we are 
proposing to require bags or other non-rigid packages containing 
asbestos to be transported in rigid outer packages or closed freight 
containers.
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. We are proposing 
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, consistently with the 
ICAO Technical Instructions, we are proposing 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).
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. We are proposing to 
revise paragraph (d) accordingly.
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 
paragraph (b)(7), we propose to add a new entry ``Acetone-pyrogallol 
copolymer 2-diazo-1-naphthol-5-sulphonate'' to the Self-Reactive 
Materials Table.
Section 173.230
    We are proposing to add a new packaging section (Sec.  173.230) for 
the transportation of ``Fuel cell cartridges containing flammable 
liquids, UN 3473'' including methanol or methanol/water solutions. For 
consistency with the ICAO Technical Instructions, we are proposing 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.
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 this NPRM, we propose 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 Sec.  173.24. 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 aerosols and small gas 
receptacles would not be subject to the shipping paper, package 
marking, or labeling requirements, a carrier might be unaware of the 
potential risks. In addition, to avoid confusion and further clarify 
the intent of this exception, we are proposing 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.
    Also, we are proposing to add a new paragraph (j) to alert readers 
to additional exceptions for compressed gases in Sec.  173.307.

Part 175

Section 175.10
    Currently, safety matches or a lighter intended for use by a 
passenger or crew member are excepted from the HMR. In accordance with 
the ICAO Technical Instructions, in this NPRM, we are proposing 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.
Section 175.78
    Section 175.78 establishes requirements for stowing hazardous 
materials on an airplane. We propose to amend 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.

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. Consistently with 
recent changes to the classification of flammable liquids based on the 
GHS and adopted into the UN Recommendations discussed elsewhere in this 
preamble, we are proposing 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).
Section 176.83
    Section 176.83 establishes segregation requirements for hazardous 
materials transported by vessel. We are proposing to revise paragraph 
(a)(4) to identify materials of different hazard classes that do not 
react dangerously with each

[[Page 51904]]

other and, therefore, do not need to be segregated.
Section 176.84
    Section 176.84 contains additional stowage and segregation 
requirements for hazardous materials on cargo and passenger vessels. 
Consistently with the 2004 Edition of the IMDG Code, incorporating 
Amendment 33-06, in the paragraph (b) Table of provisions, we are 
proposing to add a new Code ``144.''
    Code ``144'' would be added 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.
    Also, we are proposing 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 each other and the quantities per package do not 
exceed 30 L (7.8 gallons) for liquids and 30 kg (66 lbs.) for solids. 
We are also proposing to revise Codes ``26,'' ``27,'' ``52,'' and 
``53'' to add the new proposed note ``2.'' These provisions are 
consistent with the IMDG Code.

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 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 Fourteenth 
revised edition of the UN Recommendations 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 Recommendations.
    We propose 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. This requirement would take effect on January 1, 
2008, and is consistent with the international requirements. UN 
portable tanks impact-tested based on the criteria in effect on October 
1, 2005, would not need to be retested.
Section 178.602
    Section 178.602 establishes requirements for the preparation of 
packagings for testing to ascertain 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. We are proposing to revise paragraph (b) to clarify that the 
preparation of bags for the drop and stacking tests only applies to 
bags containing solids.
Section 178.810
    Section 178.810 establishes requirements for performing the drop 
test for IBCs. We are proposing 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 are proposing to require fiberboard 
and wooden IBCs to be filled with a solid material to not less than 95% 
of their maximum capacity. Also, we are proposing to add a new 
paragraph (b)(3) to require filling flexible IBCs to the maximum 
permissible gross mass and even distribution of the contents.

Part 180

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. We are proposing 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 additions incorporate 
clarifications adopted in the Fourteenth revised edition of the UN 
Recommendations. We are proposing to editorially revise paragraph (g) 
for clarity.

VI. Regulatory Analyses and Notices

A. Statutory/Legal Authority for This Rulemaking

    This proposed 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 proposed 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 proposed 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.
    2. 49 U.S.C. 5120(b) authorizes the Secretary of Transportation to 
ensure that, to the extent practicable, regulations governing the 
transportation of hazardous materials in commerce are consistent with 
standards adopted by international authorities. This rule proposes to 
amend 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 proposes to incorporate 
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. 
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 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

[[Page 51905]]

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; further, we are maintaining a number of current 
exceptions for domestic transportation that should minimize the 
compliance burden on the regulated community.

B. Executive Order 12866 and DOT Regulatory Policies and Procedures

    This proposed 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 proposed rule 
is not considered a significant rule under the Regulatory Policies and 
Procedures of the Department of Transportation [44 FR 11034]. This 
proposed rule applies to offerors and carriers of hazardous materials, 
such as chemical manufacturers, chemical users and suppliers, packaging 
manufacturers, distributors, battery manufacturers, radiopharmaceutical 
companies, and training companies. Benefits resulting from the adoption 
of the amendments in this proposed 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 proposed rule should result in 
cost savings and ease the regulatory compliance burden for shippers 
engaged in domestic and international commerce, including trans-border 
shipments within North America.
    We propose a delayed effective date and a one-year transition 
period to allow for training of employees and to ease any burden on 
entities affected by the amendments. The total net increase in costs to 
businesses in implementing the proposed 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 would result from these changes; 
however, the costs would 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 proposed rule has been analyzed in accordance with the 
principles and criteria contained in Executive Order 13132 
(``Federalism''). This proposed rule preempts State, local and Indian 
tribe requirements but does not propose any regulation that has 
substantial direct effects on the States, the relationship between the 
national government and the States, or the distribution of power and 
responsibilities among the various levels of government. Therefore, the 
consultation and funding requirements of Executive Order 13132 do not 
apply.
    The Federal hazardous material transportation law, 49 U.S.C. 5101-
5128, contains an express preemption provision (49 U.S.C. 5125(b)) that 
preempts State, local, and Indian tribe requirements on certain covered 
subjects. 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 proposed 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 proposed rule 
is necessary to incorporate changes adopted in international standards, 
effective January 1, 2007. If the changes in this proposed 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 proposed 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. PHMSA proposes the effective date of Federal 
preemption be 90 days from publication of a final rule in this matter 
in the Federal Register.

D. Executive Order 13175

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

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

    The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires an 
agency to review regulations to assess their impact on small entities, 
unless the agency determines that a rule is not expected to have a 
significant impact on a substantial number of small entities. This 
proposed rule facilitates the transportation of hazardous materials in 
international commerce by providing consistency with international 
standards. This proposed rule applies to offerors and carriers of 
hazardous materials, some of whom are small entities, such as chemical 
users and suppliers, packaging manufacturers, distributors, battery 
manufacturers, and training companies. As discussed above, under 
Executive Order 12866, the majority of amendments in this proposed rule 
should result in cost savings and ease the regulatory compliance burden 
for shippers engaged in domestic and international commerce, including 
trans-border shipments within North America.
    Many companies will realize economic benefits as a result of these 
amendments. Additionally, the changes effected by this final rule will 
relieve U.S. companies, including small entities competing in foreign 
markets, from the burden of complying with a dual system of 
regulations. Therefore, I certify that these amendments will not, if 
promulgated, have a significant economic impact on a substantial number 
of small entities.
    This proposed rule has been developed in accordance with Executive

[[Page 51906]]

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 proposed 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.
    This rule proposes minor editorial changes. 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 proposed 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 
tentatively conclude that there are no significant environmental 
impacts associated with this proposed rule. Interested parties, 
however, are invited to review the Environmental Assessment available 
in the docket and to comment on what environmental impact, if any, the 
proposed regulatory changes would have.

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; 
Pages 19477-78) or you may visit http://dms.dot.gov.

    d. any combination thereof.
    8. In Sec.  172.202, paragraphs (a) and (b) are revised to read as 
follows:


Sec.  172.202  Description of hazardous material shipping papers.

    (a) The shipping description of a hazardous material on the 
shipping paper must include:
    (1) The identification number prescribed for the material as shown 
in Column (4) of the Sec.  172.101 table;
    (2) The proper shipping name prescribed for the material in Column 
(2) of the Sec.  172.101 table;
    (3) The hazard class or division number prescribed for the 
material, as shown in Column (3) of the Sec.  172.101 table. Except for 
combustible liquids, the subsidiary hazard class(es) or subsidiary 
division number(s) must be entered in parentheses immediately following 
the primary hazard class or division number.
    In addition--
    (i) The words ``Class'' or ``Division'' may be included preceding 
the primary and subsidiary hazard class or division numbers.
    (ii) The hazard class need not be included for the entry 
``Combustible liquid, n.o.s.''
    (iii) For domestic shipments, primary and subsidiary hazard class 
or division names may be entered following the numerical hazard class 
or division, or following the basic description.
    (4) The packing group in Roman numerals, as designated for the 
hazardous material in Column (5) of the Sec.  172.101 table. Class 1 
(explosives) materials, self-reactive substances, organic peroxides and 
entries that are not assigned a packing group are excepted from this 
requirement. The packing group may be preceded by the letters ``PG'' 
(for example, ``PG II''); and

2 Class 8 materials in PG II or III that otherwise are required to be
  segregated from one another may be transported in the same cargo
  transport unit, whether in the same packaging or not, provided the
  substances do not react dangerously with each other to cause
  combustion and/or evolution of considerable heat, or of flammable,
  toxic or asphyxiant gases, or the formation of corrosive or unstable
  substances; and the package does not contain more than 30 L (7.8
  gallons) for liquids or 30 kg (66 lbs.) for solids.

PART 178--SPECIFICATIONS FOR PACKAGINGS

    42. The authority citation for part 178 continues to read as 
follows:

    Authority: 49 U.S.C. 5101-5128; 49 CFR 1.53.
    43. In Sec.  178.274, paragraph (j)(6) is revised to read as 
follows:


Sec.  178.274  Specifications for UN portable tanks.

* * * * *
    (j) * * *
    (6) Effective January 1, 2008, each new UN portable tank design 
type meeting the definition of ``container'' in 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,'' UN 
1963, and ``Hydrogen, refrigerated liquid,'' UN 1966, 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.  178.602  [Amended]

    44. In Sec.  178.602, in paragraph (b), the second sentence is 
amended by adding the wording ``containing solids'' after the word 
``Bags''.
    45. In Sec.  178.810, paragraph (b) is revised to read as follows:


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.

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.
