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:
UN0349............................ Articles, explosive, 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.
UN2671............................ Aminopyridines (o-; m-; p-).
UN1005............................ Ammonia, anhydrous.

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,
n.o.s.,'' UN3362, PG II, would be 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)
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 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.
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.
51. The entry ``Paint related material including paint thinning,
drying, removing, or reducing compound,'' UN1263, would be revised by
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.
(Solid).
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.

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

containing one or more compatible items of hazardous materials in
boxes, cases, etc. that, for example, are used for medical, analytical,
diagnostic, testing, or repair purposes. For transportation by
aircraft, materials forbidden for transportation by passenger aircraft
or cargo aircraft may not be included in the kits. Chemical kits and
first aid kits are excepted from the specification packaging
requirements of this subchapter when packaged in combination
packagings. Chemical kits and first aid kits are also excepted from the
labeling and placarding requirements of this subchapter, except when
offered for transportation or transported by air. Chemical and first
aid kits may be transported in accordance with the consumer commodity
and ORM exceptions in Sec. 173.156, provided they meet all required
conditions. Kits that are carried on board transport vehicles for first
aid or operating purposes are not subject to the requirements of this
subchapter.

47 Mixtures of solids that are not subject to this subchapter and
flammable liquids may be transported under this entry without first
applying the classification criteria of Division 4.1, provided there is
no free liquid visible at the time the material is loaded or at the
time the packaging or transport unit is closed. Except when the liquids
are fully absorbed in solid material contained in sealed bags, each
packaging must correspond to a design type that has passed a
leakproofness test at the Packing Group II level. Small inner
packagings consisting of sealed packets and articles containing less
than 10 mL of a Class 3 liquid in Packing Group II or III absorbed onto
a solid material are not subject to this subchapter provided there is
no free liquid in the packet or article.
* * * * *
77 Mixtures containing not more than 23.5% oxygen by volume may be
transported under this entry when no other oxidizing gases are present.
A Division 5.1 subsidiary risk label is not required for any
concentrations within this limit.

146 This description may be used for a material that poses a hazard
to the environment but does not meet the definition for a hazardous
waste or a hazardous substance, as defined in Sec. 171.8 of this
subchapter, or any hazard class, as defined in Part 173 of this
subchapter, if it is designated as environmentally hazardous by another
Competent Authority. This provision may be used for both domestic and
international shipments.
147 This entry 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. The mixture for emulsions typically
has the following composition: 60-85% ammonium nitrate; 5-30% water; 2-
8% fuel; 0.5-4% emulsifier or thickening agent; 0-10% soluble flame
suppressants; and trace additives. Other inorganic nitrate salts may
replace part of the ammonium nitrate. The mixture for suspensions and
gels typically has the following composition: 60-85% ammonium nitrate;
0-5% sodium or potassium perchlorate; 0-17% hexamine nitrate or
monomethylamine nitrate; 5-30% water; 2-15% fuel; 0.5-4% thickening
agent; 0-10% soluble flame suppressants; and trace additives. Other
inorganic nitrate salts may replace part of the ammonium nitrate. These
substances must satisfactorily pass Test Series 8 of the UN Manual of
Tests and Criteria, Part I, Section 18 (IBR, see Sec. 171.7 of this
subchapter), and may not be classified and transported unless approved
by the Associate Administrator.

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
(5) Except for transportation by aircraft, the total quantity of
hazardous materials covered by the description must be indicated (by
mass or volume, or by activity for Class 7 materials) and must include
an indication of the applicable unit of measurement. For example, ``200
kg'' or ``50 L.'' The following provisions also apply:
[[Page 51923]]
(i) For Class 1 materials, the quantity must be the net explosive
mass. For an explosive that is an article, such as Cartridges, small
arms, the net explosive mass may be expressed in terms of the net mass
of either the article or the explosive materials contained in the article.

the same substance but vary only in their water content (for example,
sodium sulfide in Division 4.2 or Class 8) or quantity for Class 7
materials; or
(ii) Between hazardous materials of different classes which
comprise a group of substances that do not react dangerously with each
other. The following materials are grouped by compatibility:
(A) Hydrogen peroxide, aqueous solutions with not less than 8
percent but less than 20 percent hydrogen peroxide (stabilized as
necessary); Hydrogen peroxide, aqueous solutions with not less than 20
percent but not more than 40 percent hydrogen peroxide; Hydrogen
peroxide, aqueous solutions with more than 40 percent but not more than
60 percent hydrogen peroxide; Hydrogen peroxide and peroxyacetic acid
mixtures, stabilized with acids, water and not more than 5 percent
peroxyacetic acid; Organic peroxide type D, liquid; Organic peroxide
type E, liquid; Organic peroxide type F, liquid; and
(B) Dichlorosilane, Silicon tetrachloride, and Trichlorosilane.

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
