Hazardous Materials: Harmonization With the United Nations

Recommendations, International Maritime Dangerous Goods Code, and

International Civil Aviation Organization's Technical Instructions

AGENCY: Research and Special Programs Administration (RSPA), DOT.

ACTION: Final rule.

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

SUMMARY: This final rule amends 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 revisions are necessary to facilitate the

transport of hazardous materials in international commerce.

DATES: Effective date: The effective date of these amendments is

October 1, 1997.

Compliance date: RSPA is authorizing immediate voluntary

compliance. However, persons voluntarily complying with these

regulations should be aware that petitions for reconsideration may be

received and, as a result of RSPA's evaluation of those petitions, the

amendments adopted in this final rule could be subject to further

revision.

Incorporation by reference. The incorporation by reference of

certain publications listed in these amendments has been approved by

the Director of the Federal Register as of October 1, 1997.

SUPPLEMENTARY INFORMATION:

I. Background

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 (UNCOE). These recommendations are amended and updated biennially

by the UNCOE and are distributed to nations throughout the world. They

serve as the basis for national, regional, and international modal

regulations (specifically the IMDG Code, issued by the International

Maritime Organization (IMO), and the ICAO Technical Instructions,

issued by the ICAO Dangerous Goods Panel). 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 (subject to

certain conditions and limitations).

On December 29, 1994, RSPA issued a final rule [Docket HM-215A; 59

FR 67390] amending the HMR by incorporating changes to more fully align

the HMR with the seventh and eighth revised editions of the UN

Recommendations, Amendment 27 to the IMDG Code and the 1995-96 ICAO

Technical Instructions. The final rule provided consistency with

international air and sea transportation requirements which became

effective January 1, 1995.

In a final rule published December 16, 1996, RSPA incorporated the

latest editions of the ICAO Technical Instructions and the IMDG Code

into the HMR to ensure that international shippers could begin

complying with changes to international air and vessel standards going

into effect on January 1, 1997. That final rule authorized compliance

with either Amendment 27 or Amendment 28 of the IMDG Code and either

the 1995-96 or 1997-98 ICAO Technical Instructions until June 1, 1997.

This final rule amends the HMR based on the ninth revised edition

of the UN Recommendations, the 1997-98 ICAO Technical Instructions, and

Amendment 28 to the IMDG Code. It is intended to more fully align the

HMR with international air and sea transport requirements which became

effective January 1, 1997. Other changes are based on feedback from the

regulated industry and RSPA initiatives.

II. Summary of Comments

RSPA received over 40 comments in response to the Docket HM-215B

Notice of Proposed Rulemaking (NPRM), which was published in the

Federal Register on October 25, 1996 (61 FR 55364). Comments were

submitted by chemical manufacturers, trade associations, packaging

manufacturers, and rail and vessel carriers. Commenters were supportive

of RSPA's efforts to maintain alignment with international standards.

Certain issues proposed in the NPRM received little or no comment.

Other issues, including a proposed definition for ``aerosol,'' a

proposed approval requirement for certain nitroglycerin mixtures, and

various proposed changes for organic peroxides and explosives

packagings, were the focus of most comments. Several commenters

requested transitional provisions and other amendments to the HMR as

part of this initiative. In this final rule, RSPA is providing a

delayed compliance period for implementation of these changes; however,

many other suggestions are beyond the scope of the proposed changes in

this rule and first should be the subject of an NPRM to offer adequate

opportunity for notice and comment.

III. Summary of Regulatory Changes by Section

Listed below is a section-by-section summary of changes and, as

applicable, a discussion of comments received.

Part 171

Section 171.7

RSPA proposed to add or update various American Society for Testing

and Materials (ASTM) standards, including an ASTM standard for flash

point determination (ASTM D-3828-93) which establishes whether a

material is capable of sustaining combustion in relation to classifying

flammable liquids (ASTM D-4206-96), and the ASTM standard for assessing

corrosivity to metals (ASTM G 31-72 (Reapproved 1995)). ASTM D-3828-93

is the Standard Test Method for Flash Point by

[[Page 24691]]

Small Scale Closed Tester. This method is equivalent to ASTM D-3278 but

specifically applies to testing petroleum products and lubricants. ASTM

D 4206-96 Standard Test Method for Sustained Burning of Liquid Mixtures

Using the Small Scale Open-Cup Apparatus is equivalent to the test

method currently provided in Part 173, Appendix H-Method of Testing for

Sustained Combustibility.

In addition, RSPA proposed to incorporate the most current versions

of the ICAO Technical Instructions, the IMDG Code, the UN

Recommendations and the UN Manual of Tests and Criteria. Updated

references for the IMDG Code and the ICAO Technical Instructions were

adopted in a final rule published December 16, 1996 [61 FR 65958] with

an effective date of June 1, 1997. Two references were proposed for

incorporation under the Transportation of Dangerous Goods (TDG)

Regulations issued by Transport Canada. These new entries reference

Schedule 21 and Schedule 22, which were adopted in 1995.

Section 171.8

In the NPRM, RSPA proposed several new definitions, including a

definition for ``Aerosol'' which is consistent with provisions of

Sec. 173.306(a)(3). As noted in the NPRM, the definition for aerosols

in the IMDG Code and the ICAO Technical Instructions includes

containers that are filled solely with a gas, whereas aerosol

containers authorized in Sec. 173.306(a)(3) may be charged with a gas

only for the purpose of expelling a liquid, powder or paste.

RSPA received two comments opposing the proposed definition of

``Aerosol''. Both commenters (a chemical manufacturing company and The

Chemical Specialties Manufacturers Association (CSMA)) believed the

definition in the HMR should be worded in the same manner as in the UN

Recommendations. These commenters also claimed that the proposed

definition may not cover foams, pastes, gels and other liquids which

are not ejected in suspension in a gas. CSMA further noted that the

proposed definition only recognizes metal aerosol containers while

international standards authorize glass and plastic as materials of

construction for aerosol containers.

RSPA's proposed definition for ``Aerosol'' corresponds to current

requirements for aerosols in Sec. 173.306(a)(3). Paragraph (a)(3)

contains an authorization for the use of metal nonspecification

packagings charged with a solution of materials and compressed gas or

gases (i.e., aerosols) with certain restrictions applying to internal

pressure, filling limits and testing of the container. The capacity of

this container cannot exceed 50 cubic inches or 27.7 fluid ounces.

These provisions apply only to solutions of materials and compressed

gas or gases which are not poisonous (other than Division 6.1, Packing

Group III materials). A final rule published October 28, 1991, under

Docket HM-210 [56 FR 55471], was issued for clarification and to

promote the safe transportation of gases shipped under limited quantity

provisions. This final rule stated, in part:

RSPA is concerned about the serious potential hazards posed by

shipping flammable compressed gases, under limited quantity or

consumer commodity provisions, when a compressed gas is the primary

product and not merely an aerosol propellant additive. RSPA and its

predecessor agencies never intended that gases other than those used

as a propellant could be excepted from any of the HMR when a package

has more than a 4-fluid ounce capacity.

Thus, current aerosol provisions in the HMR do not correspond to the

aerosol definition in international standards, which authorizes a gas

to be expelled ``without a liquid, paste, or powder.'' Nor does RSPA

intend to adopt such a provision, because filling a container solely

with a gas, such as butane, poses a significantly greater risk than

filling the container with a liquid, paste or powder which is expelled

by a butane gas due to greater quantities of gas contained in aerosols

that do not contain liquid, paste or powder. Furthermore, in response

to commenters' concern that the proposed definition may not cover

foams, pastes, gels and other liquids which are not ejected in

suspension in a gas, RSPA believes that because foams or gels would be

considered liquids expelled by a gas, it is not necessary to

specifically list them.

Another difference between domestic requirements for aerosols and

international standards is that the HMR authorize only metal

containers, while non-metallic (e.g., made from glass or plastic)

containers are authorized internationally. A November 13, 1995 response

to a petition for reconsideration issued under Docket HM-215A [60 FR

56957] emphasized that only metal aerosol containers are authorized for

use. This document noted that ``RSPA is not aware of any proposed

industry standards for the manufacture and use of aerosol containers

other than those made of metal.'' Nor is RSPA aware of any subsequent

ongoing action to propose industry standards for the manufacture and

use of non-metallic aerosol containers.

In addition, RSPA proposed corresponding changes in Secs. 171.11,

171.12 and 171.12a to clarify the proposed definition of aerosols as it

applies to aerosols imported in accordance with the ICAO Technical

Instructions, the IMDG Code and the TDG Regulations. These changes, as

well as the definition for aerosols, are adopted as proposed in this

final rule.

RSPA also proposed definitions for ``SADT'' (self-accelerating

decomposition temperature), salvage packagings and intermediate

packagings. No comments were received on these proposed definitions,

and they are adopted as proposed.

Sections 171.11, 171.12, and 171.12a

These sections authorize shipments prepared under the ICAO

Technical Instructions, the IMDG Code, and the TDG Regulations,

respectively. RSPA proposed to remove the requirement to include the

words ``Dangerous When Wet'' on shipping papers in association with the

basic description for Division 4.3 materials. Commenters uniformly

supported this proposal, stating that the change was compatible with

international standards and that the ``Dangerous When Wet'' hazard is

clearly communicated through indication of Division 4.3 as part of the

basic shipping description and through use of Division 4.3 labels and

placards. Therefore, RSPA is removing the requirement for ``Dangerous

When Wet'' to appear on shipping papers in association with the basic

description.

RSPA also proposed that the words ``Toxic Inhalation Hazard'' be

added as an alternative to ``Poison Inhalation Hazard'' or ``Inhalation

Hazard'' and that ``Toxic'' or ``Toxic Gas'' be added as alternatives

to ``Poison'' or ``Poison Gas''. A corresponding provision for shipping

paper descriptions was proposed for Sec. 172.203(m). Two comments

expressing opposing viewpoints were received. One commenter, an

international chemical and industrial gases manufacturer, supported

this proposal, stating that this alternative will simplify compliance

when shipping materials poisonous by inhalation. The other commenter, a

vessel carrier, believed consistency could be achieved through use of

only the ``Toxic'' designation. This commenter claimed that providing

an option for use of either term will confuse people in the field. RSPA

does not agree and is adopting the alternative ``Toxic Inhalation

Hazard'' as proposed in the NPRM. However, RSPA is not adopting

proposed modifications to

[[Page 24692]]

POISON and POISON GAS label and placard references. These references

were recently modified by the Docket HM-206 final rule [62 FR 1227] and

RSPA believes additional modifications to these references are

unnecessary.

Also, as discussed above for Sec. 171.8, RSPA is adopting a

provision to allow only aerosols meeting the definition of ``aerosol''

in Sec. 171.8 to be imported in accordance with the ICAO Technical

Instructions, IMDG Code and TDG regulations.

Section 171.14

A new paragraph (d) is added to provide a delayed implementation

date for amendments adopted in this final rule. The effective date of

this final rule is October 1, 1997. However, RSPA is authorizing an

immediate voluntary compliance date to allow shippers to prepare their

international shipments in accordance with the new ICAO, IMDG Code and

HMR provisions. RSPA is also authorizing a delayed mandatory compliance

with the new requirements, until October 1, 1998. This delay is

comparable to the transition provisions provided in the final rule

under Docket HM-215A and offers a sufficient phase-in period to

implement new provisions and deplete current stocks of shipping papers,

labels, placards, and containers affected by the new requirements. In

addition, paragraph (d)(2) permits intermixing of old and new hazard

communication requirements until October 1, 1998.

Part 172

Section 172.101

A new paragraph (c)(14) is added to allow isomers of materials

listed in the Hazardous Materials Table (HMT) which meet the same

hazard class, subsidiary risk and packing group to be identified using

the listed shipping description. One commenter suggested adding a

provision to exclude isomers listed specifically in the HMT. RSPA

agrees and is revising this paragraph to reflect the commenter's

suggestion.

A new paragraph (c)(15) is adopted to allow hydrates of inorganic

substances to be described using the proper shipping name for the

equivalent anhydrous material. In this final rule, RSPA is clarifying

the proposed regulatory text to indicate that the hydrate must meet the

same hazard class or division, subsidiary risk(s) and packing group of

the equivalent anhydrous material, unless the hydrate is specifically

identified in the Table.

Paragraph (f) is revised to acknowledge that Division 6.2 materials

(other than regulated medical waste) do not have packing group

assignments.

Changes to the HMT include:

New Packing Group I entries added for certain commodities,

including Adhesives, Resin solutions, Paint and Paint-related material,

Disinfectants, Dyes, and Oxidizing liquid, n.o.s.

An alternative proper shipping name ``Refrigerant gas'' plus the

``R'' number is added to numerous entries, consistent with the ninth

revised edition of the UN Recommendations. Current entries that contain

an italicized ``R'' number are revised to include the ``R'' number in

Roman type as part of the ``Refrigerant gas'' alternative proper

shipping name. One commenter engaged in reselling prepackaged

refrigerants expressed concern that some refrigerant manufacturers

would use the newly authorized ``Refrigerant gas, R ***'' proper

shipping name while others would continue to use the current chemical

name; consequently, a shipping paper description, package markings and

emergency response information may not match. This commenter

recommended that differences in proper shipping names resulting from

mixed use of the original and alternative proper shipping name on

markings, emergency response information and shipping papers be

authorized indefinitely, as long as the same UN or NA identification

number appears on the shipping paper, emergency response information,

and package markings. RSPA does not agree. The HMT contains numerous

entries providing an alternative proper shipping name. It is RSPA's

opinion that to offer various mix and match provisions for such entries

is impracticable and could result in greater confusion.

Certain Class 1 entries assigned NA numbers for domestic

transportation are removed. These include Explosive pest control

devices and Propellant explosives (both liquid and solid). Domestic

exceptions for these explosives are incorporated into the explosive

packing instructions, where applicable.

RSPA proposed a new entry and special provision for a nitroglycerin

mixture containing more than 2 percent but not more than 10 percent

nitroglycerin. The special provision sets forth a requirement that the

Associate Administrator for Hazardous Materials Safety (AAHMS) must

specifically authorize the nitroglycerin mixture as a Division 4.1

material, as well as approve the assigned packing group and packaging

method before the material may be transported as a Division 4.1

material. A chemical manufacturer and several pharmaceutical

manufacturers opposed this proposal. According to these commenters, a

preparation consisting of 10% nitroglycerin is used in the treatment of

acute angina attacks. They claimed that, unless this proposal is

dropped or the domestic supplier of this material is granted an

approval to ship the preparation as a Division 4.1 material,

transporting this material as a Division 1.1D explosive would have a

significant negative impact on the continued production and

distribution of this product.

RSPA does not agree. A certain preparation containing 10%

nitroglycerin was considered to be a UN 0143, 1.1D explosive by the

UNCOE in December 1994, based on the fact that the preparation

detonated in the bonfire test prescribed in test series 6(c) of the UN

Manual of Tests and Criteria. The UNCOE recognized that not all

preparations containing 10% nitroglycerin behave the same. Therefore,

the UNCOE adopted UN 3319 with a provision for each competent authority

to authorize, either by approval or exemption, a preparation consisting

of not more than 10% nitroglycerin as a Division 4.1 material based on

test results. This provision is consistent with the existing provisions

of Sec. 173.124(a)(1)(ii)(B) for desensitized explosive substances

which require authorization, either by approval or exemption, by the

AAHMS. RSPA believes that a 10% nitroglycerin preparation that will

detonate in a fire should be considered a forbidden material according

to Sec. 173.21(h). If the preparation is or may be explosive according

to Sec. 173.54(a), it is forbidden for transport unless examined and

approved under the provisions of Sec. 173.56. Depending on test

results, the same preparation may be approved under Sec. 173.56 as a

Division 4.1 material. RSPA does not believe the incorporation of UN

3319 with a lengthy transition period for shippers to obtain an

approval or exemption, where appropriate, would seriously threaten the

production of nitroglycerin pharmaceutical treatments in the United

States.

New entries are added for compressed gases and liquefied gases

which are toxic and also meet flammable, corrosive, or oxidizing

criteria.

Packaging authorizations for the current entry ``Gas, refrigerated

liquid'' are revised to reference the packaging provisions for

cryogenic liquids. In addition, two new entries ``Gas, refrigerated

liquid, flammable, n.o.s.'' and ``Gas, refrigerated liquid, oxidizing,

n.o.s.'' are added. One commenter supported the proposal to change

[[Page 24693]]

packaging authorizations for ``Gas, refrigerated liquid'' to reference

packagings for cryogenic liquids, but believed that packaging

exceptions provided in Sec. 173.320 should be authorized for ``Gas,

refrigerated liquid, n.o.s.'' and ``Gas, refrigerated liquid,

oxidizing, n.o.s.'' The commenter claimed that this section should

apply if the components of the mixture are exclusively various

combinations of atmospheric gases and/or helium in cryogenic liquid

form. RSPA agrees and is adding an exception in Column (8A) for these

two entries.

Several entries, such as Phenyl isocyanate and Phosphorous

trichloride, are amended by revising the primary hazard class in Column

(3) and/or Packing Group in Column (5). For some entries, such a change

in hazard class or packing group also results in a corresponding

removal of the ``+'' in Column (1).

In Column (2) of the HMT, several proper shipping names are listed

in Roman type, indicating that they are authorized proper shipping

names. However, they are not listed as proper shipping names under the

UN Recommendations, the ICAO Technical Instructions, or the IMDG Code.

For consistency with the international regulations, RSPA is revising a

number of proper shipping names, including ``Aircraft evacuation

slides'', from Roman type to italics to indicate that they are no

longer authorized proper shipping names.

Certain entries, such as Diphenylmethane-4,4'-diisocyanate and

Methyl benzoate (which do not meet toxicity criteria for a Division 6.1

Packing Group III material) are removed. These commodities were deleted

from the List of Dangerous Goods in the ninth revised edition of the UN

Recommendations.

The packing group designation for ``Mercury, contained in

manufactured articles'' is revised from Packing Group I to Packing

Group III for consistency with the entry for ``Mercury'' and the ICAO

Technical Instructions.

To maintain consistency with the UN Recommendations, various proper

shipping names are amended by the addition or removal of the word

``compressed'', ``inhibited'', ``liquefied'' or ``solution''. Several

commenters indicated that although they generally support the

international harmonization effort and overall intent to maintain

consistency between the HMR, the UN Recommendations, the IMDG Code, and

the ICAO Technical Instructions, they did not understand the basis for

the addition or deletion of the words ``compressed,'' ``inhibited,'' ``

liquefied'' or ``solution'' relative to clarifying certain existing

shipping names. These amendments were adopted by the UNCOE, in part, to

more effectively communicate the threat posed by certain materials in

their different physical states, e.g., pressurized materials that may

be transported as a liquid or as a gas. The description modifications

were supported by several large industry groups at the time the UNCOE

was considering the amendments.

RSPA recognizes that revising proper shipping names to include or

exclude these four modifiers to the key words identifying the hazardous

materials poses problems that makes compliance difficult in the one-

year period provided in Sec. 172.101(l)(1)(ii). Those difficulties and

the associated additional costs of compliance were highlighted in

comments provided by several shippers and carriers of industrial gases.

In consideration of those comments, RSPA is providing an exception in

Sec. 172.101(l)(3) that obviates the need for shippers and carriers to

make special arrangements to remark bulk or non-bulk packagings used in

the transportation of the affected hazardous materials within one year

following the effective date of this rule. Rather, when the proper

shipping name of a hazardous material is modified only by the addition

or omission of the word ``compressed,'' ``inhibited,'' `` liquefied''

or ``solution,'' its packaging may be marked with the previously

prescribed proper shipping name for that material for a period of five

years following the effective date of this rule. The extended

compliance period is intended to allow re-marking to be accomplished in

association with the periodic five-year retest required for most bulk

packagings.

To minimize the effects of other amendments, RSPA is incorporating

an extended transition period comparable to that provided in Docket HM-

215A. This will allow industry time to deplete current stocks of pre-

printed shipping papers, labels and packagings affected by the new

shipping names and to implement the changes within their respective

companies, including providing any necessary training to employees.

Two commenters pointed out a conflict in the proposed addition of a

Division 5.1 subsidiary risk label for the entry ``Carbon dioxide and

oxygen mixtures''. RSPA has stated previously that this subsidiary risk

should be recognized only when a mixture contains a concentration of

oxygen greater than 23.5%, requiring a subsidiary risk label for this

entry without regard to the amount of oxygen in the mixture is

inconsistent. Although the UN Recommendations prescribe a subsidiary

5.1 risk label without any distinctions, RSPA agrees with these

commenters. Therefore, a new Special Provision 77 is added to limit the

requirement for this subsidiary risk label to mixtures having an oxygen

concentration greater than 23.5% for domestic transportation. In

addition, RSPA intends to bring this inconsistency to the attention of

the UN Committee of Experts.

RSPA is adjusting quantity limits for certain materials identified

as poisonous by inhalation when transported by passenger or cargo

aircraft or passenger railcar. Many of these changes are consistent

with current quantity limits prescribed in the ICAO Technical

Instructions. Certain other materials are forbidden for transportation

by aircraft or passenger railcar because they have been identified as

meeting the criteria for poisonous by inhalation and assigned Hazard

Zone A for liquids and Hazard Zones A and B for gases.

Other changes to the HMT include: (1) Creating separate entries for

``Ammonia, anhydrous'' and ``Ammonia solutions''; (2) adding ``First

aid kits'' as an alternative proper shipping name for the entry

``Chemical kits'' if the first aid kits contain hazardous materials;

(3) combining entries for ``Chlorite solution'' and ``Hypochlorite

solutions''; (4) removing ``Methyl alcohol'' as an authorized proper

shipping name for ``Methanol'' but retaining it in italics as a cross

reference; (5) adding a Class 3 subsidiary risk in Column (6) for

several entries; and (6) creating a new entry for ``Aerosols (engine

starting fluid)'' to indicate that these aerosols are prohibited on

both passenger and cargo only aircraft.

RSPA is not incorporating various entries suggested by commenters

that were not proposed in the NPRM. As noted previously, these

suggestions are beyond the scope of the proposed changes in this rule

and should be subject to notice and comment.

Appendix B to Sec. 172.101

RSPA proposed to add, remove or revise a number of entries in the

HMR's List of Marine Pollutants. These changes are based on Amendment

27 (to the extent not already incorporated in HM-215A) and Amendment 28

of the IMDG Code. Currently, Appendix B contains a duplicate entry for

``Maneb or Maneb preparations''; however, one entry has supplemental

information in Roman type, while the supplemental information in the

other entry is shown in italics. RSPA proposed to remove the entry

listed in all Roman type. One

[[Page 24694]]

commenter indicated that the other entry should be retained for

consistency with the IMDG Code. The commenter is correct; RSPA is

retaining the entry ``Maneb or Maneb preparations with not less than 60

per cent maneb.'' In addition, several commenters suggested various

other revisions to the list and RSPA has amended the list accordingly.

Section 172.102

A new special provision 15 is added as proposed to prescribe

quantity limits and packaging for chemical kits and first aid kits.

Other special provisions are added to authorize reclassification for

certain commodities and to provide exceptions based on testing,

concentrations, or stabilization for materials such as Maneb, aqueous

solutions of inorganic solid nitrates, and Ferrocerium.

RSPA proposed to assign Special Provision 30 to the international

entry for ``Sulfur'' to indicate that this material is not subject to

the HMR when transported in a non-bulk packaging or if formed in a

specific shape. The Sulphur Institute strongly supported this change

and recommended rewording Special Provision 30 by removing the phrase

``when transported domestically''. RSPA agrees and this special

provision is revised accordingly.

One commenter suggested RSPA revise Special Provision 47 to

incorporate a special provision adopted in the ICAO Technical

Instructions which allows small packagings consisting of sealed packets

containing less than 10 ml of a Packing Group II or III flammable

liquid absorbed onto a solid material to be excepted from the HMR if no

free liquid is present in the packet. The commenter believed this

provision is consistent with a previous letter of opinion RSPA issued

concerning alcohol wipes and should be adopted as an ``A'' special

provision, at a minimum, for consistency with ICAO. RSPA agrees and is

incorporating this exception into Special Provision 47 to apply to all

modes of transport.

RSPA proposed to add a new special provision A25 to authorize

polyester resin kits in certain quantities to be packaged in non-

specification packagings for transportation by aircraft. One commenter

suggested removing this special provision, as well as Special Provision

40 (which currently is assigned to polyester resin kits), and

incorporating all packaging provisions for polyester resin kits in

Sec. 173.152. After further consideration, RSPA agrees and is adding

specific packaging provisions in Sec. 173.152 applicable to all modes

of transport for polyester resin kits.

In addition to revising the proper shipping name ``Aluminum

smelting by-products or Aluminum remelting by-products'' (formerly

Aluminum processing by-products), a new special provision B115 is

assigned to this entry to permit certain non-specification bulk

packagings for these products. Commenters representing the aluminum

industry responded favorably to this proposal. A commenter suggested

two modifications--one to add a new special provision applicable to

both non-bulk and bulk packaging to include certain materials which

exhibit corrosivity at PG II and III levels and the other to allow both

special provisions to apply to ``magnesium granules.'' RSPA is adding a

new Special Provision 128 and revising Sec. 172.101 Table entries for

UN 3096 and UN 3131 (Packing Groups II and III) to allow aluminum

smelting by-products and aluminum remelting by-products which are

described by a generic proper shipping name because they meet the

criteria for both Division 4.3 and Class 8, to be packaged in

accordance with Special Provision B115. However, RSPA is not expanding

this provision to include non-bulk packagings, nor will Magnesium

granules be assigned B115. In the NPRM, RSPA proposed a special

provision for aluminum by-products which would eliminate the need for

DOT Exemption DOT-E-11602. RSPA does not believe it appropriate at this

time to adopt, without public notice and comment, new provisions which

go beyond the relief authorized in DOT-E-11602 and proposed in the

NPRM.

Special Provision N50, which provides an exception from Class 9

labeling for marine pollutants that are not hazardous substances or

hazardous wastes, is removed. A corresponding change is made in Column

7 of the HMT to remove Special Provision N50 for the entries

``Environmentally hazardous substance, liquid (or solid) n.o.s.''

Section 172.203

RSPA is removing the requirement in paragraph (j) that the words

``Dangerous When Wet'' be annotated on shipping papers. As discussed

previously, RSPA believes that the ``Dangerous When Wet'' hazard is

adequately communicated through an indication of the Division 4.3

hazard class as part of the basic description on shipping papers.

Commenters uniformly supported this proposal and stated that the change

was compatible with international standards and that the ``Dangerous

When Wet'' hazard is clearly communicated through indication of

Division 4.3 as part of the basic shipping description, emergency

response information on the shipping paper, and use of Division 4.3

labels and placards.

The list of generic proper shipping names which require inclusion

of a technical name in paragraph (k)(3) is amended by adding several

entries for hydrocarbon gases, hydrocarbon gas mixtures, and

compressed, liquefied or refrigerated gases which have a subsidiary

hazard of oxidizer or flammability. In addition, RSPA is adding the

entry for ``Organometallic compound, water reactive, flammable,

n.o.s.'' which was inadvertently omitted in a previous rulemaking

action.

As discussed previously in Secs. 171.11, 171.12 and 171.12a, RSPA

is adding the word ``Toxic'' and the phrase ``Toxic-Inhalation Hazard''

in paragraph (m)(3) as an alternative to ``Poison''. RSPA proposed the

addition of a new paragraph (m)(4) to provide an exception from the

requirement to indicate on a shipping paper that a material is toxic if

the toxicity of the material is based solely on corrosive destruction

of tissue rather than systemic poisoning. One commenter believed this

exception should not apply to materials poisonous by inhalation, which

require additional shipping paper information to communicate the

presence of a fatal inhalation hazard. The commenter believed the

proposal was ill conceived and not beneficial to safety. After further

consideration, RSPA believes that this proposed exception may not be

appropriate for any material meeting toxicity criteria, not just a

toxic by inhalation hazard material. Therefore, proposed paragraph

(m)(4) is not adopted in this final rule.

Part 173

Section 173.3

Paragraph (c)(3) is amended to authorize the word ``SALVAGE'' as an

alternative marking for salvage drums. In addition, a new paragraph

(c)(7) is added to allow the use of salvage packagings which have been

certified and marked to UN standards. RSPA is not adopting other

marking requirements specified in the UN Recommendations such as: (1)

Adding the letter ``T'' in the package specification markings following

the package identification code (e.g. 1A2T/Y300/...); (2) annotating

the words ``SALVAGE PACKAGING'' after the basic description on the

shipping papers; and (3) adopting salvage packaging performance tests

requiring salvage packagings to be tested at the Packing Group II level

using liquid as the test medium. It is RSPA's view that

[[Page 24695]]

additional costs incurred by such marking and performance testing

requirements are not justified because salvage packaging provisions

currently prescribed in the HMR are adequate.

Two commenters addressed proposed changes to this section and both

supported RSPA's decision to retain current salvage packaging

provisions. For example, the Steel Shipping Container Institute

maintained that it could not support complete harmonization with

international salvage packaging standards until it has been clearly

determined that incidents of failure in salvage packagings meeting the

UN standards are less than those meeting current HMR requirements.

Section 173.21

The last sentence of paragraph (f) is amended to correctly

reference the UN Manual of Tests and Criteria.

Section 173.32c

Currently an IM portable tank or its compartment having a volume

greater than 5000 liters must have a minimum filling density of 80%.

RSPA proposed to increase the minimum tank or compartment size to 7500

liters, consistent with international standards. One commenter claimed

that RSPA's proposal did not go far enough and indicated that a filling

restriction on portable tanks used solely for domestic highway

transport is unjustified and precludes shippers from transporting

relatively small quantities of hazardous materials in portable tanks.

The commenter believed that a filling restriction of less than 80% for

IM portable tanks or compartments should not apply to transport by

highway. This commenter also stated that the purpose of the ``80%

rule'' was to preclude hydraulic surge that could make adequate

securing of portable tanks aboard vessels difficult and potentially

dangerous, but that surge is not a safety concern in highway transport.

RSPA disagrees that surge is not a safety concern in highway

transport of IM portable tanks. Portable tanks, when mounted on a

vehicle chassis, may have a higher center of gravity as compared to

standard cargo tank trucks. The effects of liquid movement and its

destabilizing effect at high speed and during abrupt turning can

contribute to roll-over. This effect is most predominant when ullage is

greater than 20%. Furthermore, it is RSPA's opinion that information

supplied by this commenter does not provide sufficient incentive for

RSPA to expand relief beyond that proposed in the NPRM. RSPA may

consider this matter further in future rulemaking action on the basis

of pertinent technical justification (e.g., data indicating forces

experienced during transport of portable tanks as a result of cargo

surge).

Section 173.34

Because of a printing error, in the table in paragraph (e)(18)(i),

for DOT 8 or 8AL cylinders used to transport acetylene, under ``Porous

filler requalification,'' the year ``2001'' is corrected to read

``2011'.

Section 173.60

As proposed, amendments to this section are consistent with the UN

Recommendations, are largely editorial and serve to streamline and

consolidate general requirements for packaging explosives while

eliminating redundant and unnecessary requirements. These amendments

are intended to more clearly convey general packaging requirements

applicable to packaging explosives for transportation and do not impose

new requirements.

RSPA received one comment from a company specializing in explosives

regulatory compliance. This commenter recommended adding a reference to

Sec. 173.24(e) at the end of Sec. 173.60(b)(8) and dropping proposed

(b)(8) because (b)(9) addresses compatibility. RSPA does not agree.

Section 173.60(b)(8) specifically addresses loose explosive substances

or the explosives substance of a uncased or partly cased article which

may present a sifting hazard from the package. However, RSPA believes

it may be useful to add the explanatory reference to Sec. 173.24(e) at

the end of Sec. 173.60(b)(9).

Section 173.62

RSPA proposed new explosives packaging methods in the Explosives

Table which were developed by the UNCOE, based on comments received

from the Department of Defense and explosive industry representatives,

and on competent authority approvals and exemptions issued to shippers

of explosives. These new methods are significantly more flexible than

the methods currently prescribed in the Explosives Table and

incorporate a broader range of options for authorized inner,

intermediate and outer packagings. In several instances, inner and

intermediate packagings are no longer required. Explosives Packing

Instructions are consistent with those adopted in the ICAO Technical

Instructions. In addition, many explosives (particularly those shipped

under not otherwise specified (n.o.s.) entries) which currently require

competent authority packaging approval are now assigned to specific

packing methods eliminating the requirement for the competent authority

to approve the packaging for these explosives.

A commenter asked RSPA to revise a provision for jet perforating

guns in proposed Packing Instruction US1 to allow a higher total

explosives content per tool pallet, based on a current exemption

authorizing this higher quantity of explosives. RSPA agrees and is

revising US1 to authorize up to 90.8 kg (200 pounds) total explosive

contents per pallet.

Another commenter, the Sporting Arms and Ammunition Manufacturers'

Institute (SAAMI), recommended several changes to the proposed

revisions. First, SAAMI believed the elimination of inner packaging

requirements for ``Cartridges, small arms'' (UN0012) is inconsistent

with Sec. 173.60 (b)(3) and (b)(5). RSPA does not agree. Only when

metal outer packagings are used for UN0012, would Sec. 173.60(b)(3)

require a means of prevention from contact with the cartridges. This

means could be padding or partitions and not necessarily an inner

packaging. These cartridges have their explosives substances enclosed

in an outer casing and do not require separation according to

Sec. 173.60(b)(3). RSPA believes the recessed primer well design of

most cartridges for weapons effectively protects the article from

accidental actuation. Shippers should add protection for articles that

present an actuation hazard according to Sec. 173.60(b)(5), but that

protection can be offered by means other than requiring an inner

packaging.

Secondly, SAAMI claimed that ``Small arms ammunition, ORM-D'' would

require more stringent packaging under Sec. 173.63(b)(2) than

``Cartridges, small arms'' classed as Division 1.4S and packaged in

accordance with Packing Instruction 130. RSPA believes that more

stringent packaging requirements for ORM-D materials (which are

excepted from most shipping paper, marking, labeling and placarding

provisions of the HMR) is appropriate. Furthermore, cartridges for

weapons must be clearly identified, marked and labeled as Division 1.4S

explosive articles.

SAAMI also claimed that packaging requirements for ``Cases,

cartridge, empty with primer'' (UN0055) are more stringent than for

``Cartridges, small arms'' (UN0012). RSPA believes the inner packaging

requirement for UN0055, primed cartridge cases, empty in Packing

Instruction 136 is appropriate. These cases have an exposed explosive

substance coated or deposited on the primer which could loosen and sift

out of the outer

[[Page 24696]]

packaging without the inner packaging requirement.

RSPA does not agree with SAAMI's contention that the wording in

Packing Instruction 133, regarding the authorization of trays as inner

packagings for certain explosives, is confusing. RSPA believes that

listing UN identification numbers for which the use of trays as inner

packagings is prohibited is clearer because nearly 50 percent fewer

numbers are listed.

Finally, SAAMI recommended that for ``Primers, cap type'' (UN0044),

D9 and D11 limitations assigned to current Packing Method E-142 should

be reinstated in Packing Instruction 133. RSPA does not agree. The

harmonization of the HMR to international performance-oriented

packaging requirements and with general packaging instructions for

explosives has resulted in the successful elimination of many explosive

quantity limitations per package. As a result, shipper compliance has

become easier to achieve without increased risk to the public.

Section 173.120

Paragraphs (a)(3) and (b)(3) are revised to include a reference to

ASTM D 4206 and a new paragraph (c)(1)(i)(C) is added to reference test

method ASTM D 3828.

Section 173.124

Amendments to the test methods for flammable solids, pyrophoric

materials, self heating substances and water reactive materials are

adopted as proposed. The Self-Reactive Materials Table is updated to

include seven new substances, consistent with the UN Recommendations.

In the ninth revised edition of the UN Recommendations, Figure 14.2

(Flow Chart for Self-Reactive Substances) was amended. Paragraph

(a)(2)(iv) of that chart is used to determine the generic type for a

self-reactive material.

Section 173.125

The criteria for classification and packing group assignment for

readily combustible materials of Division 4.1 is amended for

consistency with the UN Recommendations. A reference to Appendix E

(which is removed in this final rule) is replaced by references to the

UN Manual of Tests and Criteria.

In paragraph (b), the UN burning rate test and criteria for

classification is incorporated. The classification criteria for readily

combustible materials is amended to require powdered, granular and

pasty materials to be classified in Division 4.1 when the burning time

for one or more of the test runs, according to the UN burning rate test

method, is less than 45 seconds or the rate of burning is more than 2.2

mm/s. Powders of metal or metal alloys are classified in Division 4.1

when they can be ignited and the reaction spreads over the whole length

of the sample in 10 minutes or less.

Readily combustible solids are assigned to Packing Group II if the

burning time is less than 45 seconds and the flame passes the wetted

zone. Packing Group II is assigned to powders of metal or metal alloys

if the zone of reaction spreads over the whole length of the sample in

five minutes or less. Packing Group III is assigned if the burning time

is less than 45 seconds and the wetted zone stops the flame propagation

for at least four minutes. Packing Group III is assigned to metal

powders if the reaction spreads over the whole length of the sample in

more than five minutes but not more than ten minutes.

In paragraph (c), Packing Group II and III assignment criteria for

self-heating materials is revised to more accurately account for the

volume of material being transported. For instance, certain self-

heating materials which are packaged and transported in volumes less

than 3 cubic meters or in quantities less than 450 liters are not

subject to the requirements of the HMR.

In paragraph (d), the packing group assignment criteria is revised

for consistency with the UN Recommendations. These amendments do not

significantly affect the packing group assignment criteria, but are

purely editorial to clarify the meaning of ``spontaneous ignition.''

Section 173.127

RSPA is revising the definition for solid oxidizers and adding a

new definition, test and criteria for liquid oxidizers. Liquid

oxidizers would not be classified by analogy as currently required in

the HMR. The references to Appendix F (which is removed in this final

rule) are replaced by a reference to the UN Manual of Tests and

Criteria.

Paragraph (b)(1) is revised to include a statement indicating that

the material must be tested in the concentration offered for transport.

The criteria for packing group assignment is revised to specify the

ratios of solid oxidizing material and cellulose used in assessing the

burning characteristics for comparison with the burning characteristics

of potassium bromate, potassium perchlorate or potassium persulphate

and cellulose mixtures.

Paragraph (b)(2) incorporates packing group assignment criteria for

liquid oxidizers adopted in the ninth revised edition of the UN

Recommendations. Incorporating specific criteria for liquid oxidizers

provides a more precise means for shippers to classify these products

and eliminates ambiguity involved in classifying these materials by

analogy.

Section 173.128

In paragraph (c)(3) the reference to the UN Manual of Tests and

Criteria is revised to reflect its correct title. Paragraph (e) is

amended to update the reference to Figure 11.1 (Classification and

Flowchart Scheme for Organic Peroxides).

Section 173.132

A new paragraph (b)(3)(iii) is added to clarify when solid and

liquid materials are required to be tested for acute toxicity by

inhalation. One commenter recommended that RSPA remove the second

sentence in paragraph (b)(3) because proposed (b)(3)(iii) not only

addresses this issue but is more specific. RSPA does not agree. While

there is some overlap, current (b)(3) provides more details of testing

and new (b)(3)(iii) is more specific as to when tests must be run.

Current paragraph (c) is redesignated as paragraph (d), and a new

paragraph (c) is added to authorize three methods for use in

classifying and assigning packing groups to mixtures of materials

possessing oral and dermal toxicity characteristics. One commenter

pointed out that the formula in paragraph (c) is missing a ``+''

between the second and third fractions and also is missing a note found

in international standards. In this final rule, RSPA is inserting the

``+'' between the second and third fractions. RSPA intentionally did

not propose the additional note referenced by this commenter because

the note provides optional information rather than imposing a

regulatory requirement. However, for consistency with international

standards and convenience of the reader, RSPA is adding the note at the

end of paragraph (c).

Section 173.136

A new paragraph (c) is added to clarify that skin corrosion test

data developed prior to September 30, 1995, would continue to be valid.

This revision is based on a statement in the preamble to the HM-215A

final rule (December 29, 1994; 59 FR 67400) that RSPA would not require

retesting of materials classified under the previous test method in

Appendix A of Part 173.

Section 173.137

Paragraph (b) is revised to clarify that, when determining whether

a material

[[Page 24697]]

meets Class 8 Packing Group II, the material cannot meet Class 8

Packing Group I .

Section 173.152

Limited quantity provisions are added in paragraph (b)(4)(i) for

polyester resin kits for transport by all modes.

Section 173.162

A new sentence is added at the end of the paragraph to provide an

exception from the HMR for small quantities of gallium contained in

manufactured articles or apparatuses.

Section 173.166

This section is revised to remove all references to ``seat-belt

modules'', consistent with changes in the UN Recommendations. Packaging

provisions in paragraph (e) are revised to add drums, jerricans, and

plastic boxes to the array of authorized packagings. In addition to

non-specification containers currently authorized for transporting air

bags within a controlled distribution system, RSPA is also specifically

authorizing dedicated handling devices.

Section 173.185

This section is revised for consistency with changes adopted in the

ninth revised edition of the UN Recommendations and in the ICAO

Technical Instructions.

Currently there are different quantity limitations in the HMR for

determining whether lithium cells and batteries may be designated as

items of Class 9 on the basis of whether they meet the tests and

criteria provided in the UN Manual of Tests and Criteria. These

limitations also apply to lithium cells and batteries contained in

equipment. The limitations are based on whether the cells or batteries

will be transported on passenger or cargo aircraft. Consistent with the

ICAO Technical Instructions, RSPA is adopting an authorization to allow

cells containing not more than 12 grams of lithium or lithium alloy,

and batteries containing not more than 500 grams of lithium or lithium

alloy, to be designated as Class 9 when transported by passenger or

cargo aircraft. This also applies to lithium cells and batteries

contained in equipment under specified conditions.

RSPA is also expanding the types of packagings authorized for

transporting cells and batteries by aircraft to include an array of

boxes, drums and jerricans. Additionally, RSPA is eliminating the

requirement for equipment containing lithium cells and batteries to be

packaged in waterproof outer packaging if the equipment itself is

constructed to be waterproof (i.e., lifesaving equipment designed to

function in water).

One commenter indicated that his company's batteries would not pass

all the tests specified in the UN Tests and Criteria for lithium

batteries. RSPA believes the regulations as adopted provide an adequate

alternative for lithium battery manufacturers. Under Sec. 173.185 (i),

manufacturers who experience difficulty in meeting the UN Tests and

Criteria for lithium batteries may apply for an approval provided they

can demonstrate an equivalent level of safety.

Sections 173.201-173.203 and 173.211--173.213

Aluminum jerricans, 3B1 or 3B2, are added as authorized packagings

in each of these sections.

Section 173.220

Consistent with proposed changes in Sec. 176.905 for wet batteries

transported by vessel, paragraph (c)(1) is amended to remove the

reference to Sec. 176.905 and to state that a motor vehicle or

mechanical equipment which is electrically powered is not subject to

the HMR.

Section 173.224

In paragraph (b), the Self-Reactive Materials Table is amended by

adding seven new entries. The Packing Method Table for Generic Types in

paragraph (c)(3) is removed because the information is specifically

listed in the Self-Reactive Materials Table, and paragraph (c)(4) is

redesignated paragraph (c)(3).

Section 173.225

Paragraph (b) explains column headings in the Organic Peroxide

table. Specifically, paragraph (b)(2) describes the information

comprised in the column entitled ``ID Number.'' The word ``Exempt''

occasionally appears in place of an identification number, but is not

defined in Sec. 173.225. In this final rule, paragraph (b)(2) is

amended by adding a statement to clarify that the word ``Exempt,'' if

it appears in the Organic Peroxide Table, means that the material is

not regulated as an organic peroxide.

In paragraph (b)(4)(ii), the use of type B diluents for

desensitization of organic peroxides is authorized for all organic

peroxides provided that the boiling point is at least 60 deg.C (140

deg.F) greater than the SADT of the organic peroxide in a 50 kg

package. Paragraph (b)(6) is revised to indicate that lower control

temperatures are required when IBCs and bulk packagings are used.

Paragraph (c)(2), which prohibits IBCs and bulk packagings unless

authorized through an approval, is removed. The Packing Method Table

for Generic Types in paragraph (c)(3) is removed because the

information is specifically listed in the Organic Peroxides Table, and

paragraph (c)(4) is redesignated paragraph (c)(3).

Paragraph (d) is revised to consolidate two tables specifying

packagings for liquid and solid organic peroxides and self-reactive

materials into one table for both liquids and solids.

RSPA is authorizing bottom outlets for organic peroxides in bulk

packagings by removing the prohibition in the last sentence of

paragraph (e)(2) and removing paragraph (e)(3)(i)(B). Paragraph

(e)(3)(i)(C) is redesignated paragraph (e)(3)(i)(B).

Paragraph (e)(5) is revised to authorize the transport of

stabilized peroxyacetic acid, type F (containing not more than 17

percent peroxyacetic acid) in type 31A IBCs. A similar proposal made by

the United States has been approved by the UN Committee of Experts for

incorporation into the tenth revised edition of the UN Recommendations.

Section 173.226

Paragraph (c)(1) is amended to add aluminum jerricans as an

authorized packaging.

Section 173.315

When the hazard class and division assigned to ``Methylamine,

anhydrous'' was changed from Division 2.3 (poisonous gas) to Division

2.1 (flammable gas), RSPA failed to correct the Sec. 173.315 table

entry for this material by removing Notes 22 and 24. The table entry is

being corrected in this final rule.

Sections 173.316 and 173.318

RSPA proposed the addition of a requirement for mixtures of

cryogenic liquids, where charging requirements are not specifically

prescribed, to be shipped in packagings approved by the Associate

Administrator for Hazardous Materials Safety. A commenter expressed

confusion as to whether this proposal would eliminate the need for DOT

Exemption DOT-E-10001. RSPA is revising the proposed provisions in

paragraphs (d) and (f)(4) of Secs. 173.316 and 173.318, respectively,

to clarify that an approval, rather than an exemption, is needed.

Appendix E and Appendix F

As proposed, the guidelines for classification and packing group

assignment for Classes 4 and 5 are

[[Page 24698]]

removed. RSPA believes the UN Manual of Tests and Criteria is a more

appropriate reference for these test methods. The NPRM stated that by

removing Appendix E and F, RSPA will decrease the number of amendments

to the HMR necessary for consistency with the UN Manual and will reduce

the number of pages in the HMR. One commenter objected to this

proposal, claiming potential difficulty and expense in obtaining copies

of the most current version of the UN Test Manual. RSPA does not agree.

A copy of the current test manual is part of the HM-215B public record

maintained by RSPA's Dockets Unit. Upon request to the RSPA Dockets

Unit (202-366-5046), RSPA will reproduce and provide pertinent pages

from the most current UN Test Manual.

Part 175

Section 175.10

Paragraph (a)(22) is revised to allow mercury thermometers (in

addition to mercury barometers) to be carried in carry-on baggage by a

representative of a government weather bureau or similar official

agency, provided the individual advises the aircraft operator of its

presence in the baggage.

Part 176

Section 176.78

Paragraph (k), which pertains to stowage of power-operated

industrial trucks on board a vessel, is revised to correspond to

proposed revisions in Sec. 176.905.

Section 176.84

A new code 17 is added to prescribe segregation for a compressed or

liquefied gas which is toxic, flammable and corrosive.

Section 176.905

RSPA is revising requirements for transporting motor vehicles or

mechanical equipment powered by internal combustion engines by vessel

to take account of recent changes which have occurred in the IMDG Code

and in response to comments received to the NPRM and during public

outreach meetings. In Amendment 27 of the Code, the proper shipping

name ``Engines, Internal Combustion'', UN3166, was added in order to

regulate motor vehicles and other equipment powered by internal

combustion engines. However, this proper shipping name was removed and

these materials were deregulated in Amendment 28 of the IMDG Code.

Although RSPA did not propose total relief for the transport of

motor vehicles by vessel, it proposed modifying the vessel carriage

provisions to allow battery cables to remain connected in transport and

allow vehicles transported on roll-on roll-off ships to be transported

without being subject to the HMR. Additionally, revised transport

provisions for vehicles fueled with compressed gas and for certain

battery-powered vehicles were proposed to provide clarity.

One commenter suggested that RSPA remove this section from the HMR

and provide total relief for the transport of mechanical equipment

powered by internal combustion engine by vessel. RSPA believes that

total relief would not be in the best interest of safety and that

certain precautions which minimize the potential for hazardous

materials incidents involving internal combustion-powered vehicles and

equipment are warranted.

Another commenter recommended that the motor vehicle carriage

requirements in this section be adopted in the IMDG Code to alleviate

the safety and practical problems that could arise with the

deregulation of motor vehicles in Amendment 28 of the Code. Work at the

International Maritime Organization to amend the IMDG Code is beyond

the scope of this rulemaking. The commenter also noted that to require

the fuel tank to be no more than one-fourth full is somewhat arbitrary

and can be eliminated with an inspection for leaks prior to loading.

RSPA does not agree. The purpose of the quarter tank requirement is to

limit the amount of flammable vapors which would collect in an enclosed

space such as a freight container should a fuel leak occur. Although

fuel tanks sizes vary, RSPA believes that limiting the fuel present in

a vehicle's tank is a valuable safety measure necessary to alleviate

the hazard of an undetected leak during long ocean voyages. Therefore,

the proposed requirement will remain unchanged. Finally, this commenter

noted that paragraph (f) requires a fire extinguishing system capable

of alerting personnel on the bridge of a ship, which should apply

instead to the smoke or fire detection system discussed in paragraph

(g). RSPA agrees and is revising this provision accordingly.

Several provisions are added to incorporate transport safety

measures included in recently issued motor vehicle exemptions that now

allow transport of motor vehicles with batteries connected. These

provisions include a requirement for an inspection of the vehicle's

battery and associated equipment prior to loading and requiring the

removal of a vehicle's ignition key.

Part 178

Section 178.511

This section is amended to adopt requirements for aluminum

jerricans consistent with the UN Recommendations. Packaging codes 3B1

and 3B2 are added. Paragraph (b) is amended to incorporate construction

requirements for aluminum jerricans consistent with the UN

Recommendations.

Section 178.703

In paragraph (b)(6), requirements for marking inner receptacles of

31HZ2 composite IBCs are added. All inner receptacles must be marked

with the code number designating the intermediate bulk container design

type, the name or symbol of the manufacturer, the date of manufacture

and the country authorizing the allocation of the mark. In addition,

where the outer casing of a 31HZ2 IBC could be dismantled, each of the

detachable parts must be marked with the month and year of manufacture

and the name or symbol of the manufacturer.

Section 178.707

In paragraph (c)(2), a new requirement is added to indicate that

the outer packaging of 31HZ2 composite IBCs must enclose the inner

receptacles on all sides. In paragraph (c)(3) a new requirement is

added to indicate that inner receptacles of 31HZ2 composite IBCs must

consist of at least three plies of film. In paragraph (c)(6), a new

requirement is added to indicate that IBCs of type 31HZ2 must be

limited to a capacity of not more than 1250 liters.

Section 178.815

In paragraph (c)(3), the words ``which bear the stacking load'' are

added to clarify that rigid plastic IBCs and composite IBCs with

plastic outer packagings must be tested for 28 days at 40 deg.C

(104 deg.F) when the plastic outer packagings bear the stacking load.

IBCs with plastic outer packagings that are designed with metal corner

posts to bear the stacking load are not required to be tested for 28

days at 40 deg.C (104 deg.F), but must be subjected to the stacking

test for 24 hours.

IV. Rulemaking Analyses and Notices

A. Executive Order 12866 and DOT Regulatory Policies and Procedures

This final rule is not considered a significant regulatory action

under section 3(f) of Executive Order 12866 and, therefore, was not

reviewed by the Office of Management and Budget. The rule is not

considered a significant rule under the Regulatory Policies and

[[Page 24699]]

Procedures of the Department of Transportation [44 FR 11034].

The economic impact of this final rule is expected to result in

only minimal costs to certain persons subject to the HMR and may result

in modest cost savings to a small number of persons subject to the HMR

and to the agency. Most of the revised requirements adopted in this

rulemaking received industry-association support before the United

Nations Committee of Experts on the Transport of Dangerous Goods. Of

the comments received in this docket, few dealt with increased costs of

compliance. Nevertheless, RSPA believes it adequately addressed the

concerns of commenters focused on increased costs of compliance through

its adoption of a five-year extended compliance period pertaining to

package marking requirements. Because of the minimal economic impact of

this rule, preparation of a regulatory impact analysis or a regulatory

evaluation is not warranted.

B. Executive Order 12612

This final rule has been analyzed in accordance with the principles

and criteria contained in Executive Order 12612 (``Federalism'').

Federal hazardous materials transportation law, 49 U.S.C. 5701-5127,

contains an express preemption provision (49 U.S.C. 5125(b)) that

preempts State, local, and Indian tribe requirements on certain covered

subjects. Covered subjects are:

(1) The designation, description, and classification of hazardous

material;

(2) The packing, repacking, handling, labeling, marking, and

placarding of hazardous material;

(3) The preparation, execution, and use of shipping documents

related to hazardous material and requirements related to the number,

contents, and placement of those documents;

(4) The written notification, recording, and reporting of the

unintentional release in transportation of hazardous material; or

(5) The design, manufacturing, fabricating, marking, maintenance,

reconditioning, repairing, or testing of a packaging or container

represented, marked, certified, or sold as qualified for use in

transporting hazardous material.

This final rule addresses covered subjects under items (1), (2),

(3), and (5) above and, if adopted as final, would preempt State,

local, or Indian tribe requirements not meeting the ``substantively the

same'' standard. Federal hazardous materials transportation law

provides at Sec. 5125(b)(2) that if DOT issues a regulation concerning

any of the covered subjects DOT must determine and publish in the

Federal Register the effective date of Federal preemption. The

effective date may not be earlier than the 90th day following the date

of issuance of the final rule and not later than two years after the

date of issuance. RSPA has determined that the effective date of

Federal preemption for these requirements will be [insert date 180 days

after issuance of final rule] under this docket. Thus, RSPA lacks

discretion in this area, and preparation of a federalism assessment is

not warranted.

C. Regulatory Flexibility Act

This final rule incorporates changes adopted in the ninth revised

edition of the UN Recommendations, the 1997-98 ICAO Technical

Instructions, and Amendment 28 to the IMDG Code. It applies to offerors

and carriers of hazardous materials and facilitates the transportation

of hazardous materials in international commerce by providing

consistency with international requirements.

This final rule will affect small business entities that ship or

transport hazardous materials, but any adverse economic impact should

be minimal. Certain costs incurred through changes to hazard

communication and classification requirements will be minimized through

a lengthy optional compliance period, which will allow a sufficient

phase-in period to implement new provisions and deplete current

inventory affected by the new requirements. If changes already

incorporated in international standards are not adopted in this final

rule, U.S. companies, including numerous small entities competing in

foreign markets, will be at an economic disadvantage by being forced to

comply with a dual system of regulation.

Based on readily available information concerning the size and

nature of entities likely affected by this final rule, I certify this

rule will not have a significant economic impact on a substantial

number of small entities under criteria of the Regulatory Flexibility

Act.

D. Paperwork Reduction Act

The requirements for information collection have been approved by

the Office of Management and Budget (OMB) under OMB control numbers

2137-0034 for shipping papers and 2137-0557 for approvals. Under the

Paperwork Reduction Act of 1995, no person is required to respond to a

collection of information unless it displays a valid OMB control

number.

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.
