SUMMARY: This notice proposes to amend the Hazardous Materials
Regulations to maintain alignment with corresponding provisions of
international standards. Because of recent changes to the International
Maritime Dangerous Goods Code (IMDG Code), the International Civil
Aviation Organization's Technical Instructions for the Safe Transport
of Dangerous Goods by Air (ICAO Technical Instructions), and the United
Nations Recommendations on the Transport of Dangerous Goods (UN
Recommendations), these proposed revisions are necessary to facilitate
the transport of hazardous materials in international commerce.

DATES: Comments must be received by September 6, 1994.

ADDRESSES: Address comments to the Dockets Unit (DHM-30), Research and
Special Programs Administration, U.S. Department of Transportation,

SUPPLEMENTARY INFORMATION: On December 21, 1990, the Research and
Special Programs Administration (RSPA) published a final rule [Docket
HM-181; 55 FR 52402] which comprehensively revised the Hazardous
Materials Regulations (HMR), 49 CFR Parts 171 to 180, with respect to
hazard communication, classification, and packaging requirements, based
on the UN Recommendations. One intended effect of the rule was to
facilitate the international transportation of hazardous materials by
ensuring a basic consistency between the HMR and international
regulations.
The UN Recommendations are not regulations, but are recommendations
issued by the UN Committee of Experts on the Transport of Dangerous
Goods. These recommendations are amended and updated biennially by the
Committee of Experts and are distributed to nations throughout the
world. They serve as the basis for international modal regulations;
specifically the IMDG Code, issued by the International Maritime
Organization (IMO), and the ICAO Technical Instructions. In 49 CFR
171.12, the HMR authorize shipments prepared in accordance with the
IMDG Code if all or part of the transportation is by vessel, subject to
certain conditions and limitations. Offering, accepting and
transporting hazardous materials by aircraft, in conformance with the
ICAO Technical Instructions, and by motor vehicle either before or
after being transported by aircraft, are authorized in Sec. 171.11
(with certain exceptions).
On December 22, 1992, RSPA issued an interim final rule [Docket HM-
215; 57 FR 60738] amending Sec. 171.7 by incorporating the 1993-1994
edition of the ICAO Technical Instructions and Amendment 26 to the IMDG
Code. This rulemaking action authorized the use of the updated
international regulations, effective January 1, 1993. Amendment 26
promulgated numerous miscellaneous changes to the IMDG Code regarding
classification, labeling, packaging, and documentation. The 1993-1994
edition of the ICAO Technical Instructions contained amendments
relating to the seventh revised edition of the UN Recommendations, as
well as changes specific to air transportation.
The HMR, as revised under Docket HM-181, are largely based on the
sixth revised edition of the UN Recommendations. Selected provisions
from the seventh and eighth revised editions of the UN Recommendations
have been incorporated into the HMR under subsequent Docket HM-181
rulemaking actions. This NPRM seeks to more fully align the HMR with
the seventh and eighth revised editions of the UN Recommendations.
These proposed changes to the HMR will provide consistency with the
international air and sea transport requirements which, effective
January 1, 1995, will be aligned with the eighth revised edition of the
UN Recommendations.
While the changes introduced in the seventh and eighth revised
editions are extensive and in some cases very detailed, some of the
more significant changes are highlighted below.
Major changes in the seventh revised edition include:

--Definitions and criteria for the classification for gases were
revised, three subdivisions for gases were created, and the physical
states of gases were defined (e.g. liquefied gas, refrigerated
liquefied gas, etc). Gases listed in the UN Recommendations were
reclassified according to the agreed criteria. This effort will lead to
improved harmonization of U.S. and European requirements for the
classification of gases. These changes have already been incorporated
in the HMR in Subpart D of Part 173.
--Training requirements similar to those introduced into Part 172
Subpart H of the HMR under Docket HM-126F were added.
--Criteria for self-reactive substances assigned to Division 4.1 were
developed. The applicable test methods and criteria for self-reactive
substances are based on organic peroxide tests and criteria. New
generic proper shipping names for self-reactive substances were
introduced.
--A number of new ``Not Otherwise Specified'' (N.O.S.) proper shipping
names for substances in Class 4 and Division 5.1 were introduced.
Proposals for introducing the new names originated from efforts in
Europe to adopt the classification criteria for Class 4 and Division
5.1 into European road and rail regulations.
--Provisions defining conditions under which minor variations of tested
design-type packagings and requirements for ``V'' marked packagings
were added. Proposals to include these requirements originated in the
U.S. out of concern for the extent of testing that would otherwise be
required to certify packagings in accordance with the UN performance
standards. These provisions have already been adopted in the HMR in
Subpart M of Part 178.

Major changes in the eighth revised edition include:

--Numerous additional types of packaging were added to the explosive
packing instructions. This was largely a U.S. initiative arising from a
concern for the number of packagings that would otherwise have to be
authorized through exemptions.
--Provisions for elevated temperature materials were added. These
provisions are consistent with those adopted in the HMR under Docket
HM-198A.
--Criteria defining substances not able to sustain combustion were
included. The criteria for flammable liquids were amended so that
certain substances which meet the flash point criteria for flammable
liquids, but which are shown to be incapable of sustaining combustion,
are excepted from the Recommendations. This proposal was originally
proposed by the United Kingdom, which had similar provisions in its
domestic regulations.
--The criteria for corrosive substances were modified to reference the
Organization for Economic Cooperation and Development test protocol for
skin corrosivity and to clarify the extent of skin damage needed for
substances to be classified as corrosives. This was done in response to
initial proposals by Germany and the European chemical industry.
--A number of new N.O.S. proper shipping names for substances in Class
3, Division 6.1 and Class 8 were introduced. Proposals for introducing
the new names originated from efforts in Europe to adopt the
classification criteria for these hazard classes into European road and
rail regulations. Proper shipping names for petroleum products also
were updated as part of this effort.
--The Recommendations were amended to require that a package bear
labels representing each subsidiary risk of a material described using
an N.O.S. proper shipping name. This amendment was based on a proposal
made by the United Kingdom.
--The current Division 6.1 Packing Group III label was deleted. For a
more detailed discussion of the events leading to this decision, see
RSPA's Notice 93-21 under Docket HM-217 published in the Federal
Register on November 8, 1993 [58 FR 59224].
--Requirements for a freight container packing certificate were added
on the basis of a United Kingdom proposal seeking to bring the UN
Recommendations in line with the IMDG Code requirements.
--A number of substances meeting the criteria of Division 6.1 Packing
Group I toxic by inhalation were reclassified based on U.S. proposals.
--Provisions on the marking of steel drums used to transport dangerous
goods and provisions clarifying the requirements applicable to drum
reconditioners and remanufacturers were included on the basis of
proposals by the International Association for Drum Reconditioners
(ICDR).
--Detailed test criteria for lithium batteries were added. The new
provisions allow batteries with a higher lithium content to be excepted
from regulation if they meet new tests and criteria. The initial
proposal on this topic was introduced by Canada.
--Criteria under which air bag modules and air bag inflators could be
transported as Class 9 items were introduced. Proper shipping names for
these articles were also added. These changes were made on the basis of
U.S. proposals.

With a few exceptions described in this paragraph, the following
changes are proposed to ensure a basic consistency with many changes
contained in the seventh and eighth revised editions of the UN
Recommendations, the 1993-1994 and the 1995-1996 ICAO Technical
Instructions, and Amendments 26 and 27 of the IMDG Code. However,
proposed changes to the KEEP AWAY FROM FOOD label and placard
provisions will be addressed in a notice of proposed rulemaking under
Docket HM-217. In addition, proposed amendments to provisions for
Division 6.2 materials (infectious substances) will be addressed in a
separate rulemaking action under Docket HM-181G. Although the eighth
revised edition of the UN Recommendations adopted a quality assurance
program for the manufacture of performance packagings, RSPA is not
proposing a formal quality assurance program in this document. RSPA
believes that periodic retest provisions in Subpart M of Part 178 offer
an equivalent measure of quality assurance, but RSPA may propose
adoption of a more formal quality assurance program in a future
rulemaking action. Comments are solicited on this issue.

Summary of Proposed Regulatory Changes by Section

Part 171

Section 171.7. Various standards such as those issued by the
International Organization for Standardization (ISO) and the American
Society for Testing and Materials (ASTM) would be added or updated, and
the most current versions of the ICAO Technical Instructions, the IMDG
Code, and the UN Recommendations would be incorporated.
Section 171.8. New definitions for ``Asphyxiant gas,'' ``Gas'' and
``Siftproof packaging'' would be added, and definitions for ``Box,''
``Liquid,'' ``Overpack'' and ``Solid'' would be revised for consistency
with the seventh and eighth revised editions of the UN Recommendations.
The definition for ``UN standard packaging'' would be revised to
clarify that it applies to both U.S-manufactured and foreign-
manufactured packagings and to delete reference to Subparts L and M of
Part 178.
Section 171.11. Paragraph (d)(5) would be revised to include the
word ``toxic'' when referring to a poison.
Section 171.12. Paragraph (c) would be revised to clarify that this
paragraph applies only to the shipment of hazardous materials through
U.S. port areas in the course of being transported from one foreign
country to another.
In addition, paragraph (b) would be revised for the following
reasons. RSPA received three petitions for rulemaking requesting an
amendment to the HMR to require a container packing certification
attesting that the freight container has been properly packed, stowed,
segregated and secured for transport. Those responsible for packing the
unit would be required to provide a certificate or declaration to the
carrier for international transportation by vessel.
A freight container packing certification requirement was adopted
several years ago under Amendment 24 to the IMDG Code and became
effective worldwide on January 1, 1994, as mandated under the
International Convention on Safety of Life at Sea (SOLAS Convention).
When hazardous materials are packed into a freight container or
transport vehicle for transportation by vessel, those responsible for
packing the unit must provide a certificate or declaration to the
carrier attesting that the container is suitable for transport, that it
contains compatible materials in packages that have been properly
inspected, packed, and secured, and the container and packages are
properly marked, labeled, and placarded. This certification may appear
either in a separate document or in a signed statement provided on the
dangerous goods shipping document.
Because the U.S. is a signatory to the SOLAS Convention,
petitioners urged RSPA to adopt a similar container packing
certification requirement under the HMR. RSPA is proposing to amend
Secs. 171.12(b) and 176.27(c) to reference IMDG Code requirements for a
container packing certification for freight containers and transport
units intended for carriage by vessel. A ``unit'' could be a freight
container, van trailer, or other transport vehicle. This requirement
would apply to persons who load hazardous materials for transportation
(including freight forwarders, freight consolidators and non-vessel
operating common carriers) or transport hazardous materials by vessel.
Section 171.14. Paragraph (c)(3) contains provisions for
intermixing old and new hazard communication requirements. Because of
the October 1, 1993 mandatory compliance date for new hazard
communication requirements, these provisions no longer apply.
Therefore, paragraph (c)(3) would be removed and reserved.

Part 172

Sections 172.101 and 172.102. RSPA is proposing to revise the
Hazardous Materials Table (HMT) and the list of special provisions in
Sec. 172.102 for basic conformance with the eighth revised edition of
the UN Recommendations, the ICAO Technical Instructions (1995-1996
edition) and the 27th edition of the IMDG Code. Under Docket HM-181,
the HMT was revised by consolidating the existing HMT, the Optional
Table in Sec. 172.102, the UN Recommendations' List of Dangerous Goods,
the ICAO Dangerous Goods List, the IMDG Code list of dangerous goods,
the list of dangerous goods found in Canada's Transport of Dangerous
Goods (TDG), and the IM Tank Table. The IM Tank Table, though not
codified in the HMR, authorized the transport of hazardous materials in
intermodal (IM) portable tanks. The Optional Table contained in the
pre-HM-181 HMR was the table used for selection of proper shipping
names to be used in domestic and international transportation by
vessel.
RSPA consolidated the tables under Docket HM-181 to simplify the
use and reduce the volume of the HMR, as well as to align HMR hazard
communication and classification requirements with the UN
Recommendations. Since publication of HM-181, the UN, ICAO, and IMO
have incorporated changes to their lists of dangerous goods. If RSPA
does not incorporate comparable changes to the HMT, the result will be
two sets of regulations (one for domestic and one for international
transportation) and confusion in the regulated community--which could
result in unsafe shipments and restrictions on international trade. In
addition, by not adopting such changes, RSPA will expend considerable
resources reviewing and issuing approvals and initiating separate
rulemakings to authorize shipments prepared in accordance with the
international standards.
Proposed changes to shipping descriptions are based primarily on
Chapters 2 and 3 of the UN Recommendations. In turn, the changes to the
IMO and ICAO lists of dangerous goods also are based on the UN
Recommendations. Proposed changes include additions, deletions and
revisions of shipping names, classifications, subsidiary hazards,
labeling requirements, and packing group assignments--such as adding or
changing a material's packing group. In addition, RSPA proposes to
permit a special provision to be assigned to a shipping description to
clarify the composition of a material described under a specific entry.
Except for certain materials, such as elevated temperature
materials and sodium batteries, proposed changes to a material's
packaging authorizations are based on a material's packing group and
subsidiary hazard, and physical state (solid, liquid, or gas).
Packaging authorizations would be consistent with corresponding entries
already appearing in the HMT. For example, the non-bulk packaging
section for a Class 3, Packing Group I material would be Sec. 173.201.
A Division 6.1, Packing Group III material would be assigned
Sec. 173.153 for a possible packaging exception, while a Division 6.1,
Packing Group I or II material would receive no packaging exception
section. A Class 8, Packing Group I liquid material would be assigned
Sec. 173.243 for bulk packaging requirements while a Class 8, Packing
Group II liquid material would be assigned to Sec. 173.242. It is
important to note that any change to a material's classification,
packing group, or subsidiary hazards could have an effect on the
material's packaging authorizations.
Under HM-181, IM tank authorizations were consolidated into the HMT
(through the use of special provisions prefaced by a ``T'') and were
consistent with the sixth revision of the UN Recommendations. In this
notice, RSPA is proposing to revise the IM tank authorizations for
consistency with the changes in Chapter 12 of the seventh and eighth
revised editions of the UN Recommendations. These proposed changes can
be found in the ``T-note'' authorizations that are listed in Column 7
of the HMT.
The aircraft quantity limitations in Column 9 and the vessel
stowage requirements in Column 10 would be revised for consistency with
the ICAO Technical Instructions and IMDG Code, respectively. In
Sec. 172.101(k)(1)-(k)(5), the definitions of the vessel stowage codes,
which are prescribed in the Sec. 172.101 Table, would be revised for
consistency with the IMDG Code. This proposed revision would broaden
current stowage provisions for hazardous materials on cargo vessels to
apply to hazardous materials (such as propane) on passenger vessels
carrying a limited number of passengers.
Changes proposed to the HMT are quite extensive--approximately 33%
of the entries in the HMT would be changed. Therefore, RSPA is
publishing the entire proposed HMT in this notice, but does not believe
it is necessary to discuss every proposed change in this section
review. However, in order to facilitate the reader's understanding of
the changes to the HMT, RSPA is providing a list of all entries that
would be added, deleted, or made more restrictive. This list includes
changes in (1) the shipping name, (2) IM tank authorization, (3)
subsidiary labeling, (4) classification, and (5) packaging. In
addition, a discussion of some of the more substantive changes is
provided.
Many proper shipping names were added in the 1995-1996 ICAO
Technical Instructions to reflect both singular and plural forms. The
eighth revised edition of the UN Recommendations added a provision
allowing the use of either the singular or plural form of a proper
shipping name. RSPA is not proposing to add separate entries in the HMT
to indicate both the singular and plural form of a proper shipping name
because Sec. 172.101(c)(1) currently permits use of either form.
Numerous editorial changes would be made to the HMT to correct
misspellings and errors, and to provide more consistency. An entry
having only a typographical error corrected is not shown in the list of
significant changes. Therefore, it is necessary to review the entire
HMT to determine every proposed change.
Currently under the HMR, compressed and liquefied gases of the same
material have the same shipping description and identification number
(I.D. number). RSPA is proposing to split the generic shipping
descriptions for ``Compressed or Liquefied gases'' into separate
entries and add new generic entries and I.D. numbers for liquefied
gases, consistent with the UN Recommendations. In addition, new generic
entries would be added for self-heating liquids and solids. Specific
entries for self-reactive materials would be removed from the HMT and
replaced with new generic entries.
The UN Recommendations, ICAO Technical Instructions, and IMDG Code
replaced the term ``poisonous'' with the term ``toxic.'' RSPA is
proposing to amend the proper shipping names in the HMT that contain
the word ``poisonous'' by replacing the word ``poisonous'' with the
word ``toxic'' to conform to international terminology. For example,
the proper shipping name ``Flammable liquid, poisonous, n.o.s.'' would
be revised to read ``Flammable liquid, toxic, n.o.s.''. However,
Sec. 172.101(c)(3) would be revised to allow the use of the word
``poisonous'' interchangeably with the word ``toxic''.
The words ``inorganic'' and ``organic'' would be added to certain
generic shipping descriptions. Comments are invited regarding the
safety benefits of these modified descriptions, and as to whether there
is a need for domestic exceptions. In addition, RSPA is proposing to
add new generic entries for a corrosive material to indicate whether
the material is ``basic'' or ``acidic.'' RSPA also is proposing to add
new entries, as adopted in the UN Recommendations, for solid materials
containing flammable, corrosive, or toxic liquids.
The eighth revised edition of the UN Recommendations added entries
and assigned new UN I.D. numbers for elevated temperature materials.
RSPA is proposing to change the I.D. numbers for elevated temperature
materials in the HMT to correspond with those in the UN
Recommendations.
Currently under the HMR, air bags are assigned to the Division 4.1
hazard class and the proper shipping name is limited to ``Air bag
inflators'' or ``Air bag modules.'' Based on changes in the UN
Recommendations, RSPA would revise the proper shipping name for air
bags to include seat belt pre-tensioners and modules. The new proper
shipping name would be ``Air bag inflators or Air bag modules or Seat-
belt modules or Seat-belt pre-tensioners.'' This entry also would
reflect a change in classification from Division 4.1 to Class 9,
adoption of a new UN number, and removal of the ``D'' in Column 1.
Two new domestic entries would be added for ``Toy caps'' and ``Toy
propellant devices''. Toy propellant devices containing 30 grams or
less propellant would be classed as Division 1.4S while items
containing more than 30 grams but not more than 62.5 grams would be
classed as Division 1.4C.
Two new entries for ``Batteries, containing sodium'' and ``Cells,
containing sodium'' would be added in the HMT based on the UN
Recommendations entry (UN 3292). Since these materials were previously
authorized only under the terms of an exemption or competent authority
approval, RSPA is proposing to add a new packaging section Sec. 173.189
that prescribes general packaging and transport requirements for these
materials consistent with the UN Recommendations.
Currently, in Column 1, a ``+'' is assigned to certain materials
meeting the criteria of Division 6.1, Packing Group I, toxic by
inhalation, but classed in another hazard class. The eighth revised
edition of the UN Recommendations incorporated revisions to the hazard
classification of these materials to Division 6.1, Packing Group I,
toxic by inhalation. Therefore, the ``+'' would be removed from Column
1 for any liquid poison by inhalation (PIH) material newly classed in
Division 6.1, Packing Group I.
The shipping name ``acetonitrile'' is proposed to replace the name
``methyl cyanide.'' The hazard class for ``Formaldehyde solutions''
currently shown as Class 9 would be revised to Class 8. Numerous
generic pesticide entries would be revised to remove the ``n.o.s.''
from the shipping names.
Previously under the UN Recommendations, ICAO Technical
Instructions, and the IMDG Code, a subsidiary hazard of Division 6.1,
Packing Group III was not recognized. However, the international
standards now take such a subsidiary hazard into account. Therefore,
numerous entries would appear for the first time with a Division 6.1,
Packing Group III subsidiary hazard. In addition, an exception in
Sec. 172.101(c)(12)(iii), which allows a subsidiary hazard of Division
6.1, Packing Group III to be disregarded when selecting a proper
shipping name, would be removed.
Revised generic shipping descriptions for Division 4.3 materials
would be prefaced by the words ``water-reactive'' in lieu of the words
``substances which in contact with water emit''. The prefix of the
identification number for ``Polyester resin kits'' would be changed to
``UN'' from ``NA'' and a special provision ``40'' would be added in
Column 7 that would specify contents and packaging requirements for
polyester resin kits. In addition, Special Provision ``117'' would be
removed from the entry corresponding to ``UN 0150.''
The entry for alcoholic beverages would be revised in Column 7 to
include Special Provision ``24'', which would indicate that alcoholic
beverages with more than 70 percent alcohol by volume would be assigned
Packing Group II and alcoholic beverages containing more than 24
percent but not more than 70 percent alcohol would be assigned Packing
Group III. In addition, Sec. 173.150 would be revised to increase (to
five liters per inner packaging) the quantity of alcoholic beverage in
a packaging excepted from the HMR and to provide an exception adopted
in the UN Recommendations to permit Packing Group III alcoholic
beverages transported in receptacles of 250 L (66 gallons) or less to
be excepted from the HMR unless transported by air.
The following tables identify those entries that would be: (1)
deleted; (2) significantly changed; or (3) added. An entry is
considered significantly changed if there is a change in (1) the
shipping name, (2) IM tank authorization, (3) subsidiary labeling, (4)
classification, or (5) packaging. Each entry is identified by its
identification number which, along with the cross-reference table
appearing in the HMR prior to the HMT, can be used to identify the
affected entries. Unless otherwise indicated, the identification
numbers are ``UN'' numbers:

------------------------------------------------------------------------

Appendix B to Sec. 172.101. In a November 5, 1992 final rule
entitled ``Marine Pollutants'' [57 FR 52934], RSPA stated that it would
consider, in a future rulemaking action, a criteria-based system to
identify marine pollutants. Adoption of a criteria-based system would
provide continuity and harmony, as well as permit identification of
potential pollutants previously not identified. Therefore, RSPA is
proposing to add two notes which are consistent with recent IMO
decisions. The first, Note 4, would allow a material meeting criteria
for a marine pollutant in the IMDG Code but not listed in Appendix B of
Sec. 172.101, to be transported as a marine pollutant. Note 5 would
allow the Associate Administrator for Hazardous Materials Safety to
except from HMR requirements a material listed in Appendix B of the HMR
that does not meet the IMDG Code criteria for a marine pollutant. In
addition, a number of materials would be added to, or removed from, the
HMR's List of Marine Pollutants.
Section 172.102. Special Provisions 23, 24, 26, 32, 34-40, and 43-
51 would be added to Sec. 172.102. These special provisions relate to
certain materials' classifications and any special packaging
requirements that are necessary to safely transport these materials.
Due to an oversight, Special Provision 23 was already added in a final
rule published June 2, 1994 [Docket HM-166Z; 59 FR 28493]. This special
provision concerned classification of ammonium nitrate fertilizer.
Special Provision 23 in this notice does not apply to ammonium nitrate
fertilizer and is not intended to revise the recently adopted Special
Provision 23. However, because of a time constraint and the difficulty
in amending Column 7 of the HMT, the new provision will be proposed in
this notice under Special Provision 23, but will be renumbered to
Special Provision 38 in the final rule under Docket HM-215A.
Section 172.203. A new paragraph (o) would be added to require
additional information to be included in the shipping paper description
for organic peroxides and self-reactive materials. In addition,
paragraphs (k) and (m) would be revised based on changes to the HMT. In
paragraph (k), the list of shipping names requiring technical names
would be revised based on changes to the HMT. In paragraph (m), the
reference to ``Poison'' would be modified to include an alternative
reference to ``Toxic.''
Section 172.204. The certification statement in paragraph (a)(2)
would be revised to add ``placarded'' as a condition for declaring a
shipment to be properly prepared for transportation. This wording is
consistent with international declarations and would enable one shipper
certification statement to be used for both domestic and export
shipments so that different preprinted forms are not needed.
Section 172.320. Section 172.320 would be revised to permit all
product codes that are traceable to an ``EX-number'' to be marked on
boxes of explosives in lieu of the EX number.
Section 172.400a. A new paragraph (c) would be added to state that
a subsidiary POISON label is not required on a package bearing a
primary CORROSIVE label if the poison hazard of the material inside is
based solely on corrosive destruction of tissue and is not due to
systemic poisoning. This provision was omitted inadvertently in the
Docket HM-181 final rule, and reinstating it would be consistent with
international requirements.
Section 172.402. For consistency with revisions to the UN
Recommendations, ICAO Technical Instructions, and the IMDG Code,
labeling for certain subsidiary hazards would be required. The
subsidiary labeling table in paragraph (a)(2) would be revised to
exclude Class 3 Packing Group III subsidiary risk materials having a
flash point at or above 38 deg.C (100 deg.F) from the requirement to
label, except when transporting the materials by air or vessel. This
proposed revision would require that a material having a subsidiary
risk of Class 3 Packing Group III and a flash point below 38 deg.C
(100 deg.F) be labeled for the Class 3 subsidiary hazard in accordance
with this section. In addition, the exception from subsidiary hazard
labeling for Class 8 Packing Group III and Division 6.1 Packing Group
III materials transported by highway or rail would be removed.
Previously, a Division 6.1 Packing Group III subsidiary hazard was not
required internationally or domestically. Based on a change adopted in
the eighth revised edition of the UN Recommendations, which removed the
STOW AWAY FROM FOODSTUFFS label and placard, packages containing
materials having either a primary or subsidiary hazard in Division 6.1
Packing Group III are required to bear a POISON label. As noted
previously in this document, RSPA is addressing this issue in a
rulemaking action under Docket HM-217. However, RSPA believes that a
package containing a material meeting Division 6.1 Packing Group III
criteria as either a primary or subsidiary hazard should bear a label
which communicates a warning that the material must be kept separate
from foodstuffs. Therefore, RSPA is proposing that any material having
a subsidiary hazard of Division 6.1 Packing Group III must bear a KEEP
AWAY FROM FOOD subsidiary label when transported domestically by any
mode. Also, new subsidiary labeling requirements for Class 2 materials
would, under this proposal, be added as paragraphs (f) and (g).
Section 172.411. A requirement specifying a minimum height for the
compatibility group letter on certain EXPLOSIVE labels would be
removed.
Section 172.416. Section 172.416 would be revised to allow the use
of the words ``TOXIC GAS'' on the POISON GAS label.
Section 172.430. Section 172.430 would be revised to allow the use
of the word ``TOXIC'' on the POISON label.
Section 172.540. Section 172.540 would be revised to allow the use
of the words ``TOXIC GAS'' on the POISON GAS placard.
Section 172.547. Section 172.547 would be revised to reduce the
size requirement for the word ``spontaneously'' in the ``SPONTANEOUSLY
COMBUSTIBLE'' placard from 25 mm to 12 mm.
Section 172.554. Section 172.554 would be revised to allow the use
of the word ``TOXIC'' on the POISON placard.

Part 173

Section 173.2a. Consistent with the UN Recommendations, the
Precedence of Hazards Table would be amended to account for
combinations of Division 4.2 and Class 8 materials which currently are
denoted as impossible combinations. In addition, a new footnote 5 would
be added to the paragraph (b) table to specify that, for materials
having multiple risks which are not listed by technical name in the
Sec. 172.101 Table, the most stringent packaging group must be used.
Also, a note would be added to the paragraph (b) table to specify the
class assignment for a material which meets the definition of Class 8,
has an inhalation toxicity by dusts and mists at the Packing Group I
level and meets criteria for oral or dermal toxicity.
Section 173.21. A reference to the Sec. 173.224 self-reactive
materials table would be revised to reflect proposed changes to the
table.
Section 173.22. Paragraph (a)(3)(i) would be revised to indicate
that the marking appearing on the bottom of a metal or plastic drum in
accordance with Sec. 178.503 would not be an acceptable means of
determining if the drum is an authorized packaging.
Section 173.24. Paragraph (d) would be revised to specify the
conditions under which foreign-manufactured packagings may be used. The
proposed revision would stipulate the conditions under which foreign-
manufactured UN packagings may be filled and used in the U.S. Under
this proposal, only packagings from countries affording the same degree
of acceptance to U.S.-manufactured packagings may be used. Current
provisions of the regulations authorize their use only for import/
export shipments under Secs. 171.11 and 171.12. In addition, paragraph
(e)(4)(ii) would be revised to prohibit hazardous materials from being
packed or mixed with other hazardous or nonhazardous materials in the
same outer packaging if such materials are capable of reacting with
each other and causing the evolution of ``asphyxiant gases.''
Section 173.25. Paragraph (a) would be amended to refer to the
definition of ``Overpack'' in Sec. 171.8, which also would be amended
to provide examples of suitable overpacks. Paragraph (b) would be added
to authorize shrink-wrapped or stretch-wrapped trays as outer
packagings for inner packagings prepared under limited quantity or
consumer commodity provisions if the completed package is capable of
meeting the Packing Group III performance level and the gross weight of
the package does not exceed 20 kg.
Section 173.28. Paragraph (b)(4), as revised under the Docket HM-
181 final rule, currently requires that metal and plastic single
packagings meet certain minimum thicknesses and that the ``minimum''
thickness be marked on the package. Since issuance of the Docket HM-181
final rule, the eighth revised edition of the UN Recommendations and
the international regulations have adopted a provision that metal drums
with a capacity greater than 100 liters must be marked in accordance
with tolerances allowed under ISO standard 3574 for each nominal
thickness of steel.
Unless the below-described proposed changes to Sec. 173.28 are
adopted, thicknesses and thickness marking requirements that differ
between the HMR and international regulations could result in
confusion, with drum users and reconditioners unsure whether drums are
suitable for reuse or remanufacture. Drum manufacturers in the U.S.
might find it necessary to mark both minimum and nominal thicknesses on
each drum in order to satisfy DOT and international requirements.
Consistent with changes proposed in Sec. 178.503(a), RSPA is proposing
that metal drums and jerricans which are to be reused be marked with
the nominal thickness, in millimeters. The minimum thickness table in
paragraph (b)(4) would be revised for metal drums and jerricans to
reflect a minimum thickness corresponding to the minimum allowed under
ISO standard 3574 for various nominal thicknesses. In developing the
minimum thickness proposed for each listed capacity of packaging, the
thickness chosen is that most closely corresponding numerically (i.e.,
without regard to whether it is thicker or thinner) to the minimum
thickness previously required. That is, based on the tolerances allowed
under ISO 3574 for each nominal thickness of steel, the minimum
thickness corresponding to that nominal thickness was determined and
compared to the minimum thickness required under the current provisions
for the given capacity of packaging. Each proposed minimum thickness
would result in a minimum sheet thickness closely corresponding to that
required under the current regulations. However, for packagings with a
capacity up to and including 120 liters, the proposed minimum
thicknesses would result in slight increases in the required thickness.
Drums would continue to be suitable for reuse only if they meet the
minimum thickness criteria of the table in paragraph (b)(4). A person
reusing a metal drum or jerrican could not rely on the thickness
marking appearing on the packaging to satisfy the minimum thickness
requirements, since that marking would represent the nominal, rather
than the minimum, thickness in accordance with proposed
Sec. 178.503(a)(9). Because the eighth revised edition of the UN
Recommendations did not address thickness requirements for plastic
packagings, RSPA is not proposing any changes to the thickness
requirements for plastic packagings.
Based on the merits of a petition for rulemaking (P-1133), a new
paragraph (b)(7) would be added to waive retesting requirements for
certain packagings used in limited operations prior to each reuse. The
petitioner states that this proposed change would provide consistency
with corresponding provisions in international requirements. According
to both the HMR and the UN Recommendations, a packaging must be design-
qualification tested before use. However, unlike the HMR, the UN
Recommendations do not require a packaging to be leakproof tested
before it is reused for transport, but only after it is reconditioned.
Packagings that are reused without reconditioning include metal drums
that are refilled with the same or similar compatible contents and
transported within distribution chains controlled by the consignor of
the product. RSPA is proposing similar provisions in new paragraph
(b)(7) for certain packagings to be reused without leakproof testing.
Packagings would be limited to stainless steel, monel, or nickel drums
(or other packagings approved by the Associate Administrator for
Hazardous Materials Safety) refilled with the same or similar
compatible contents and transported by a private carrier, contract
carrier, or common carrier in a transport vehicle or freight container
used exclusively for such service, within a distribution chain
controlled by the offeror. In order to ensure an appropriate level of
safety, when stainless steel, monel, or nickel drums are reused without
undergoing leakproof testing, they would be required to meet more
stringent thickness standards than prescribed in paragraph (b)(4).
Other packagings could qualify only if approved by the Associate
Administrator for Hazardous Materials Safety. Packagings also would
require an inspection prior to each reuse, and any packaging showing
evidence of a reduction in integrity would not be authorized for reuse
without reconditioning.
Section 173.33. Paragraph (c)(5) would be revised to limit the
provisions of the paragraph to materials in Packing Groups I and II of
Division 6.1.
Section 173.52. In Sec. 173.52, the description of Compatibility
Group B would be revised to clarify that detonators and similar
articles are included within this description even if they do not
contain primary explosives. In addition, in the descriptions for
Compatibility Groups E and F, the word ``gel'' would be added to
clarify that articles with a propelling charge containing gel may not
be classified in Compatibility Group E or F.
Section 173.59. In Sec. 173.59, the definitions ``powder,
smokeless,'' ``propellants,'' and ``charges, propelling'' would be
revised and definitions for ``charges, propelling for cannon,''
``propellent, liquid,'' and ``propellant, solid'' would be added.
Section 173.60. In Sec. 173.60, paragraph (b)(15) would be added to
require all plastic packagings to be static-resistant.
Section 173.62. In Sec. 173.62, the Explosives Table would be
revised to add new descriptions for Class 1 materials. In addition, the
packing method for UN0075 and UN0143 would be revised to E-159. The
Table of Packing Methods would be editorially revised to change the
reference to steel and aluminum boxes from 4A1 or 4A2 and 4B1 or 4B2 to
4A and 4B, respectively. Several packing methods would be revised by
authorizing aluminum boxes (4B) as an alternate packaging. For clarity,
the entire proposed Explosive Packing Methods Table has been reprinted
with the Table of Particular Packaging Requirements and Exceptions
following. Paragraph (e) would be revised to update the military
packaging exception to allow explosives packaged prior to January 1,
1990, to be transported in accordance with the packaging provisions in
effect on that date.
Section 173.115. The definition of a Division 2.2 gas would be
expanded to include asphyxiant and oxidizing gases.
Section 173.120. Definitions for Class 3 liquids would be revised
to include provisions for evaluating a material's ability to sustain
combustion and to measure flame point. A new method of testing for
combustibility would be referenced and added as Appendix H to Part 173.
Specific exceptions consistent with the UN Recommendations would be
added as paragraphs (a)(3), (a)(4), and (a)(5). In addition, references
to ASTM standards would be revised to reflect updated versions.
Paragraph (b)(2) would be revised to clarify that an elevated
temperature material in Class 3 may not be reclassed as a combustible
liquid. As explained more fully in a notice of proposed rulemaking and
in a final rule issued under Docket HM-198A [54 FR 38931; September 21,
1989 and 56 FR 49981; October 2, 1991], when a liquid is intentionally
heated to a temperature that is equal to or greater than its flash
point, flammable vapors are produced above the liquid. If these
flammable vapors are exposed to an ignition source, an explosion or
fire could result.
Section 173.121. Criteria for including viscous Class 3 materials
in Packing Group III would be revised. ISO method ISO 1523-1983 would
be referenced for determination of flash point. Several modifications
to the method would be provided when the temperature of the flash point
is too low for the standard procedures. Reference to ISO method 2431-
1989 would reflect the latest revision. The table in
Sec. 173.121(b)(1)(iv) would be amended for consistency with the eighth
revision of the UN Recommendations.
Section 173.124. The definition of self-reactive materials would be
revised to conform to the changes in the UN Recommendations, which now
contains ``generic'' shipping descriptions. When a new self-reactive
material is introduced into commerce, its transportation hazards
currently are determined based on standard tests. The competent
authority then assigns the new self-reactive material to a generic type
based on the test results.
In the proposed revision to Sec. 173.124, seven types of self-
reactive material (Types A-G) are defined in paragraph (a)(2). The
procedure for assigning a specific self-reactive material to a generic
type is set forth in paragraph (a)(2)(vi). If a self-reactive material
is identified by technical name in the Self-Reactive Materials Table in
Sec. 173.224, the generic type is assigned in that Table. The lengthy
process by which importing and exporting countries agree on the
packaging requirements or assignment of a shipping description for a
new self-reactive material would be avoided by using this procedure.
Section 173.128. Editorial changes would be made in paragraphs (a),
(c)(2) and (c)(3), and procedures for obtaining approvals would be
clarified in revised paragraph (d).
Sections 173.136 and 173.137. The definition and packing group
assignment for Class 8 materials would be clarified. Specific test
protocols developed by the Organization for Economic Cooperation and
Development (OECD) and published in the 1992 OECD Guideline for Testing
of Chemicals, No. 404, ``Acute Dermal Irritation/Corrosion'' would be
incorporated. A copy of this guideline may be obtained from the OECD
Publications and Information Center, 2001 L Street, Suite 700,
Washington, DC 20036 or by contacting the RSPA Dockets Unit.
Section 173.150. Paragraph (a) would be revised to allow Class 3
materials that meet the definition of Class 8 Packing Group III or
Division 6.1 Packing Group III, to utilize limited quantity exceptions
provided in this section. Paragraph (b) would be expanded to include
limited quantity exceptions for combustible liquids to provide relief
from specification packaging and placarding requirements for
combustible liquids which are also hazardous substances or hazardous
wastes. The paragraph (d) provisions for alcoholic beverages would be
revised to clarify that an alcoholic beverage containing 24 percent or
less alcohol by volume is not subject to the HMR. The maximum quantity
per package of alcoholic beverage excepted from the HMR would be raised
from four liters to five liters, and a Packing Group III alcoholic
beverage in a packaging of 250 L or less would not be subject to the
HMR unless transported by air.
Section 173.152. The limited quantity provisions for organic
peroxides would be amended by increasing the authorized net capacity
per inner packaging for Type D, E, or F liquid and solid organic
peroxides and Type B or C solid organic peroxides. However, the
authorized net capacity for liquid Type B or C organic peroxides would
decrease from 30 ml to 25 ml per inner packaging.
Section 173.164. Certain exceptions for mercury (metallic and
articles containing mercury), would be clarified and a 4H2 solid
plastic box would be authorized as an outer packaging, consistent with
the ICAO Technical Instructions.
Section 173.166. This section would be amended to limit its
applicability to air bag inflators and modules showing certain
specified results when subjected to a bonfire test. Under this proposed
revision, airbag modules and inflators not meeting the test criteria
must be transported as explosives.
Section 173.168. This section would be added to define a
``nonspillable battery'', establish separate requirements for
nonspillable batteries (as opposed to the requirements for wet
batteries contained in Sec. 173.159), and provide vibration and
pressure differential testing criteria. Except when transporting a
wheelchair or other battery-powered mobility aid equipped with a non-
spillable battery by air as checked baggage, a nonspillable battery
which is protected against short circuits, securely packaged and
durably marked would not be subject to any other HMR requirements.
Section 173.171. Paragraph (a) would be revised to clarify that
smokeless powder must be examined and approved as both Division 1.3 and
Division 4.1.
Section 173.185. RSPA is proposing to amend the requirements for
lithium batteries consistent with changes in the UN Recommendations.
While the new requirements apply more severe test requirements to
lithium batteries, they also will allow batteries with higher
quantities of lithium to be transported without being subject to the
regulations, provided specified criteria are met. Existing batteries
previously allowed to be transported as Class 9 batteries may continue
to be transported under the present requirements indefinitely if the
present requirements are met.
Section 173.189. This new section would be added to establish the
packaging and general transport requirements for batteries and cells
containing sodium. The packagings and transport conditions proposed
reflect those prescribed for these articles in the UN Recommendations,
the ICAO Technical Instructions and the IMDG Code. Specific conditions
under which batteries containing liquid sodium may be transported are
proposed based on the conditions prescribed for the transport of
batteries containing liquid sodium under DOT-E 10917.
Section 173.196. The seventh edition of the UN Recommendations
revised a provision for infectious substances packagings to require
that either the primary receptacle or the secondary packaging be
capable of withstanding the prescribed pressure differential. RSPA is
proposing a similar revision to paragraph (f) to clarify that both the
inner and the outer packagings are not required to have this
capability.
Sections 173.211-213. These sections would be revised to change
packaging identification codes (for steel boxes from 4A1 and 4A2 to 4A
and for aluminum boxes from 4B1 and 4B2 to 4B) for consistency with
international requirements.
Section 173.224. This section would be revised based on the UN
Recommendations. Paragraph (b) sets forth the Self-Reactive Materials
Table which identifies the technical name for specific self-reactive
materials, the identification number which is used to select the
appropriate generic shipping description, specifications for
concentrations of the self-reactive material, packing methods that may
be used, temperature control requirements, and additional special
provisions. The existing packing methods for self-reactive materials
would be replaced with the packing methods for organic peroxides which
are prescribed in Sec. 173.225.
Paragraph (c) sets forth procedures for new self-reactive
materials, formulations and samples. New self-reactive materials and
formulations of currently identified self-reactive materials would have
to be approved in accordance with the provisions in
Sec. 173.124(a)(2)(vi). Paragraph (c)(4) contains provisions for the
shipping of samples of new formulations. Paragraph (d) would specify
that self-reactive materials of Type F may be transported in bulk only
under the approval of the Associate Administrator for Hazardous
Materials Safety.
Section 173.225. In Sec. 173.225, paragraph (a) would be revised to
prohibit the use of metallic non-bulk packagings meeting a Packing
Group I packaging standard. Paragraph (c)(5) would be added to
authorize the transportation of mixtures of organic peroxides that are
specifically identified in the Organic Peroxides Table without approval
by the Associate Administrator for Hazardous Materials Safety. In
addition, the Organic Peroxide Table would be revised to add new
organic peroxides adopted in the UN Recommendations.
Section 173.304. In the paragraph (a)(2) table, for the entry
``carbon dioxide,'' an erroneous reference to a DOT-311800 cylinder
would be corrected to authorize a DOT-3T1800 cylinder for carbon
dioxide.
Section 173.306. In paragraph (a)(3)(v), the hot water immersion
test for aerosols and small gas receptacles would include a reference
temperature of 50 deg.C (122 deg.F) in addition to the reference
temperature of 55 deg.C (131 deg.F). A reference temperature of 50
deg.C would be permitted if the liquid phase of the materials contained
in the receptacle does not exceed 95 percent of the capacity of the
receptacle at 50 deg.C. In addition, provisions would be added for
plastic receptacles or contents which are sensitive to heat.
Appendix A to Part 173. Appendix A, which provides a method of
testing corrosion to skin, would be removed and reserved for
consistency with proposed changes to the definition and packing group
assignment for Class 8 materials.
Appendix E to Part 173. New criteria would be added for self-
reactive materials possessing explosive properties, and an editorial
change would be made to clarify that powders of metals or metal alloys
that can be ignited are classified in Division 4.1.
Appendix F to Part 173. In paragraph 1., an editorial revision
would be made to correctly reference Division 5.1.
Appendix H to Part 173. A new Appendix H would be added to Part 173
to provide a method of testing for combustibility. This method outlines
a procedure for determining if a material can sustain combustion if
heated under test conditions and exposed to an external source of
flame.

Part 175

Section 175.10. The phrase ``environmental restoration or
protection'' would be added as an exception in paragraph (a)(12) to
clarify that certain aircraft operations pertaining to environmental
restoration may be conducted under the provisions of this paragraph.
Exceptions currently contained in paragraphs (a)(13) and (a)(17) for
carbon dioxide (dry ice) would be consolidated into paragraph (a)(13)
to except this material from regulation from Part 175 when it is used
as a refrigerant for a package, intended for use in food or beverage
service aboard an aircraft, or when used to pack perishables in carry-
on baggage. Paragraph (a)(4) would be revised for consistency with the
ICAO Technical Instructions which prohibit the carriage of undeclared
flammable aerosols in checked or carry-on luggage. The carriage of such
aerosols may create an unnecessary risk to ground handlers, passengers,
and air crew members. In addition, a new paragraph (a)(26) would be
added to except from regulation small medical or clinical mercury
thermometers carried by passengers or crew members for personal use.
Section 175.33. Paragraph (a)(1) would be revised and a new
paragraph (a)(9) would be added to require an aircraft operator, in the
written notification to the pilot-in-command, to include a
compatibility group letter for a Class 1 material and an air waybill
number where one has been issued.

Part 176

Section 176.27. A new paragraph (c) would be added to reference a
container packing certificate required under the provisions of the
SOLAS Convention. (See discussion under Sec. 171.12 of this section
review for additional information.)
Section 176.76. A new paragraph (i) is being proposed for inclusion
in Sec. 176.76 to address the transport of fumigated transport units on
vessels. These proposed fumigation requirements would be in addition to
the fumigation requirements contained in Sec. 173.9. The new vessel
requirements are generally consistent with the IMDG Code requirements
for transporting fumigated transport units and are consistent with
Special Permits currently being issued by the Coast Guard for U.S.
maritime transport of fumigated transport units. Contrary to the IMDG
Code but consistent with the UN Recommendations, RSPA is not proposing
that fumigated units be treated as items of Class 9. If the proposed
requirements for fumigated transport units on vessels are adopted in
the final rule, a Special Permit issued by the Coast Guard would no
longer be necessary.

Part 177

Section 177.841. Paragraph (e)(3) would be revised to specify
requirements for separating Division 6.1 Packing Group III materials
from foodstuffs, consistent with provisions in Sec. 177.848.

Part 178

Section 178.2. Paragraph (a) would be revised to clarify that Part
178 requirements for UN standard packagings apply only to packagings
manufactured in the U.S. See Sec. 173.24(d)(2) for foreign-manufactured
packagings. A new paragraph (e) would be added to include definitions
for ``manufacturer'' and ``specification markings.'' These new
definitions would specify who is to be identified through a
specification marking as the ``manufacturer'' and would clarify the
manufacturer's responsibility under Part 178.
Section 178.3. The introductory text in paragraph (a) and the text
in subparagraph (a)(2) would be revised editorially for clarity. A new
marking provision would be added to paragraph (a)(4) to permit markings
of an appropriate, rather than specific, size for packagings of 5 L (1
gallon) or 5 kg (11 pounds) or less capacity. Paragraph (b) would be
revised to clarify the requirements for UN standard packagings marked
in accordance with HMR requirements and UN standard packagings marked
in accordance with the ICAO Technical Instructions or the IMDG Code.
Section 178.502. In paragraph (a) introductory text and paragraph
(a)(1), the terms ``type'' or ``types'' of packagings would be amended
for consistency with international regulations to read ``kind'' or
``kinds'' of packagings.
Section 178.503. Consistent with the UN Recommendations, RSPA is
proposing revisions to certification marking requirements in this
section. Each packaging certified to a UN standard is required to have
a series of markings which describe the packaging and its
characteristics. Paragraph (a) would be revised to require, for
packagings having a gross mass greater than 30 kg (66 pounds), that
these markings appear on the top or side of the packaging. Currently,
Sec. 178.503 requires that metal or plastic drums or jerricans intended
for reuse be marked with the minimum thickness of the packaging
material. Consistent with the UN Recommendations, RSPA is proposing
that metal drums and jerricans intended for reuse be marked with the
nominal thickness. The nominal thickness marked would be in accordance
with ISO 3574; that is, the nominal thickness marked could only exceed
the actual minimum thickness of the packaging material by the tolerance
specified in ISO 3574. Packagings to be reused would still be subject
to the minimum thickness requirements of Sec. 173.28. Because the
eighth revised edition of the UN Recommendations did not address
thickness requirements for plastic packagings, RSPA is proposing that
plastic drums and jerricans intended for reuse continue to be marked
with the minimum thickness of the packaging material.
In addition to the full marking on the top or side of a metal or
plastic drum having a capacity greater than 100 liters and intended for
reuse or reconditioning as a single packaging or the outer packaging of
a composite packaging, RSPA is proposing to require a permanent marking
of the drum characteristics on the bottom of the drum. The country
authorizing the mark, the name and address of the manufacturer, and the
packaging thickness would not be required as part of this permanent
mark. This marking would identify the packaging as it was originally
manufactured, and could not necessarily be used to determine compliance
with packaging requirements. For example, if a non-removable head drum
had been converted to a removable head drum, this conversion would not
be reflected in the marking on the bottom of the drum, but would be
evident in the top or side marking. For drums marked permanently on the
bottom, the top or side mark would not be required to be permanent
(i.e., able to withstand the reconditioning process).
RSPA is proposing a new paragraph (d), which would specify
additional requirements for markings on reconditioned metal drums. The
paragraph would require that reconditioners reapply markings which no
longer appear on drums after the reconditioning process. A
reconditioner could duplicate the original markings or apply markings
which reflect a lower performance level, but could not apply markings
which identify a performance level greater than that for which the
original design type had been tested and marked.
Section 178.512. Standards for steel boxes and aluminum boxes would
be consolidated by removing the distinction between unlined/uncoated
steel or aluminum boxes and steel or aluminum boxes having an inner
liner or coating. Therefore, both unlined and lined steel boxes would
be identified as 4A and unlined and lined aluminum boxes would be
identified as 4B. Corresponding revisions would be reflected in the
packaging authorizations of Part 173.
Section 178.513. A new paragraph would be added to the standards
for natural wood boxes to specify fastening requirements.
Section 178.516. In paragraph (b)(1), the reference to ISO Standard
535-1976(E) would be updated. Paragraph (b)(2) would be revised to
authorize the ends of fiberboard boxes to be constructed of suitable
materials other than wood, which is already authorized.
Section 178.521. In paragraph (b)(2), the term ``water-resistant''
would be revised to ``waterproof'' and examples of a waterproof ply or
barrier would be provided.
Section 178.522. A composite packaging consisting of a plastic
receptacle in a protective plastic drum is designated as 6HH in the
current HMR standards. The UN Recommendations recently adopted a new
composite packaging standard to authorize a plastic receptacle in a
protective plastic box. Therefore, in paragraph (b)(3), the previous
6HH composite packaging would be redesignated as 6HH1 and the new
composite packaging (the plastic receptacle in a protective plastic
box) would be designated as 6HH2.
Section 178.601. Based on the merits of a petition (P-1195),
paragraph (b) would be revised to limit the responsibility of shippers
to those packaging assembly functions they actually perform or are
responsible for performing. The petitioner claims that Sec. 178.601(b)
currently requires any shipper who closes a package to ensure that each
package is capable of passing prescribed performance tests, thereby
making the shipper legally responsible for every aspect of the
manufacture and testing of the packaging. RSPA agrees, and is proposing
a revision to paragraph (b)(2) to remove the shipper responsibility
provision regarding packaging fabrication and testing functions not
performed by the shipper. Paragraph (g)(2)(i) would be revised to
clarify that selective testing under Variation 2 would require the
fragile inner packagings to contain liquids. A new sentence would be
added to the end of paragraph (g)(2)(vi) to clarify that where outer
packagings are not leakproof or siftproof and consequently require some
type of leakproof liner, plastic bag or other means of containment,
sufficient absorbent material must be placed inside the liner or bag. A
new paragraph (k) would be added to permit several tests to be
performed on one sample if the validity of test results is not affected
and if approved by the Associate Administrator for Hazardous Materials
Safety. Newly designated paragraph (l) would be revised to clarify
recordkeeping requirements and provide consistency with test report
requirements in the UN Recommendations.
Section 178.602. In paragraph (c) a reference to
``Sec. 178.603(d)(2)'' would be corrected to read ``Sec. 178.603(e)''.
Section 178.603. In paragraph (a), a new provision would be added
to require that the drop test be performed using the package
orientation most likely to result in failure if more than one
orientation is possible. Paragraph (c) would be revised to clarify that
the cold drop test outlined in this paragraph applies only to plastic
packagings. A proposed revision to paragraph (f)(1) would clarify that
inner packagings of combination packagings are not required to be
vented to reach equilibrium after the drop test.
Section 178.604. For consistency with a change in the UN
Recommendations, the length of time to conduct a leakproofness test,
other than for production testing, would be specified as five minutes
in revised paragraph (d).

Rulemaking Analyses and Notices

A. 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 rule is not
considered a significant rule under the Regulatory Policies and
Procedures of the Department of Transportation [44 FR 11034]. A
preliminary regulatory evaluation is available for review in the
Docket.

B. Executive Order 12612

This proposed rule has been analyzed in accordance with the
principles and criteria contained in Executive Order 12612
(``Federalism''). The Hazardous Materials Transportation Act contains
an express preemption provision (49 App. U.S.C. 1804(a)(4)) that
preempts State, local, and Indian tribe requirements on certain covered
subjects. Covered subjects are:
(i) the designation, description, and classification of hazardous
materials;
(ii) the packing, repacking, handling, labeling, marking, and
placarding of hazardous materials;
(iii) the preparation, execution, and use of shipping documents
pertaining to hazardous materials and requirements respecting the
number, content, and placement of such documents;
(iv) the written notification, recording, and reporting of the
unintentional release in transportation of hazardous materials; or
(v) the design, manufacturing, fabrication, marking, maintenance,
reconditioning, repairing, or testing of a package or container which
is represented, marked, certified, or sold as qualified for use in the
transportation of hazardous materials.
This notice of proposed rulemaking addresses covered subjects under
items i, ii, iii and v above and, if adopted as final, would preempt
State, local, or Indian tribe requirements not meeting the
``substantively the same'' standard. The HMTA (49 App. U.S.C.
1804(a)(5), as amended, provides that if DOT issues a regulation
concerning any of the covered subjects, after November 16, 1990, 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. RSPA has determined that the
effective date of Federal preemption for these requirements will be
[insert date six months after date of publication]. Thus, RSPA lacks
discretion in this area, and preparation of a federalism assessment is
not warranted.

C. Regulatory Flexibility Act

This proposed rule would incorporate changes introduced in the
seventh and eighth revised editions of the UN Recommendations, the
1993-1994 and 1995-1996 ICAO Technical Instructions, and Amendments 26
and 27 to the IMDG Code. It would apply to offerors and carriers of
hazardous materials and would facilitate the transportation of
hazardous materials in international commerce by providing consistency
with international requirements. U.S. companies, including numerous
small entities competing in foreign markets, will be forced to comply
with a dual system of regulation, to their economic disadvantage, if
the changes proposed in this NPRM are not adopted. The proposed changes
are intended to avoid this result. I certify that this proposal will
not, if promulgated, have a significant economic impact on a
substantial number of small entities. This certification is subject to
modification as a result of a review of comments received in response
to this proposal.

D. Paperwork Reduction Act

The requirements for information collection have been approved by
the Office of Management and Budget (OMB) under the provisions of the
Paperwork Reduction Act Of 1980 (Pub. L. 96-511) under OMB control
number 2137-0034 for shipping papers and 2137-0557 for approvals.

E. Regulation Identifier Number (RIN)

A regulation identifier number (RIN) is assigned to each regulatory
action listed in the Unified Agenda of Federal Regulations. The
Regulatory Information Service Center publishes the Unified Agenda in
April and October of each year. The RIN number contained in the heading
of this document can be used to cross-reference this action with the
Unified Agenda.
