Implementation of the United Nations Recommendations, International Maritime Dangerous Goods Code, and International Civil Aviation Organization's Technical Instructions

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,

Washington, DC 20590-0001. Comments should identify the docket and be

submitted in five copies. Persons wishing to receive confirmation of

receipt of their comments should include a self-addressed stamped post

card. The Dockets Unit is located in Room 8421 of the Nassif Building,

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.

follows:

Sec. 171.8 Definitions and abbreviations.

[Add:]

* * * * *

Asphyxiant gas means a gas which dilutes or replaces oxygen

normally in the atmosphere.

* * * * *

Gas means a material which, at a standard pressure of 101.3 kPa

(14.7 psi), has a vapor pressure greater than 300 kPa (43.5 psi) at 50

deg.C (122 deg.F) or is completely gaseous at 20 deg.C (68 deg.F).
