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: RSPA is amending the Hazardous Materials Regulations (HMR) to 
maintain alignment with international standards by incorporating 
various amendments, including changes to proper shipping names, hazard 
classes, packing groups, special provisions, packaging authorizations, 
air transport quantity limitations and vessel stowage requirements. 
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: The effective date of these amendments is January 1, 2005
    Delayed Compliance Date: Unless otherwise specified, compliance 
with the amendments adopted in this final rule is required beginning 
January 1, 2006.
    Incorporation by Reference Date: The incorporation by reference of 
the publications adopted in Sec.  171.7 of this final rule have been 
approved by the Director of the Federal Register as of January 1, 2005.

I. Background

    On December 21, 1990, RSPA (we) published a final rule (Docket HM-
181; 55 FR 52402) based on the UN Recommendations, which 
comprehensively revised the Hazardous Materials Regulations (HMR), 49 
CFR Parts 171 to 180, for harmonization with international standards. 
Since publication of the 1990 final rule we have issued five additional 
international harmonization final rules (Dockets HM-215A, 59 FR 67390; 
HM-215B, 62 FR 24690; HM-215C, 64 FR 10742; HM-215D, 66 FR 33316; and 
HM-215E, 68 FR 44992). The rules provided additional harmonization with 
international transportation requirements by more fully aligning the 
HMR with the corresponding biennial updates of the UN Recommendations, 
the IMDG Code and the ICAO Technical Instructions.
    The UN Recommendations are not regulations, but rather are 
recommendations issued by the UN Committee of Experts on the Transport 
of Dangerous Goods (TDG) and on the Globally Harmonized System of 
Classification and Labeling (GHS). These recommendations are amended 
and updated biennially by the UN Committee of Experts. They serve as 
the basis for National, regional, and international modal regulations; 
specifically, the IMDG Code issued by the International Maritime 
Organization (IMO), and the ICAO Technical Instructions issued by the 
ICAO. In 49 CFR 171.12, the HMR authorize domestic transportation of 
hazardous materials shipments prepared in accordance with the IMDG Code 
if all or part of the transportation is by vessel, subject to certain 
conditions and limitations. In Sec.  171.11, subject to certain 
conditions and limitations, the HMR authorize the offering, acceptance 
and transport of hazardous materials by aircraft, and by motor vehicle 
either before or after being transported by aircraft, provided the 
shipment is in accordance with the ICAO Technical Instructions.
    The continually increasing amount of hazardous materials 
transported in international commerce warrants the harmonization of 
domestic and international requirements to the greatest extent 
possible. Harmonization serves to facilitate international 
transportation and at the same time ensures the safety of people, 
property and the environment. While the intent of the harmonization 
rulemakings is to align the HMR with international standards, we review 
and consider each amendment on its own merit. Each amendment is 
considered on the basis of the overall impact on transportation safety 
and the economic implications associated with its adoption into the 
HMR. Our goal is to harmonize without diminishing the level of safety 
currently provided by the HMR and without imposing undue burdens on the 
regulated public. In our efforts to continue to align the HMR with 
international requirements, this final rule incorporates changes into 
the HMR based on the Thirteenth Revised Edition of the UN 
Recommendations, Amendment 32 to the IMDG Code, and the 2005-2006 ICAO 
Technical Instructions, which become effective January 1, 2005. 
Petitions for rulemaking concerning harmonization with international 
standards and additional measures concerning facilitation of 
international transportation are also addressed in this final rule and 
serve as the basis of certain amendments. Other amendments are based on 
feedback from the regulated industry, other DOT modal administrations 
and our initiative. Also included are various editorial clarifications. 
Unless otherwise stated, the revisions are for harmonization with 
international standards.

II. Overview of Changes in This Final Rule

    Amendments to the HMR in this final rule include, but are not 
limited to the following:

--Amendments to the Hazardous Materials Table (HMT) which add, revise 
or remove certain proper shipping names, hazard classes, packing 
groups, special provisions, packaging authorizations, bulk packaging 
requirements, passenger and cargo aircraft maximum quantity limitations 
and vessel stowage provisions.

[[Page 76045]]

--Amendments to the List of Marine Pollutants.
--Revisions and additions of special provisions.
--Removal of the air eligibility marking requirement.
--Addition of a ``KEEP AWAY FROM HEAT'' marking requirement for 
packages offered for transportation by air.
--Amendment to require that aerosols that are carried aboard an 
aircraft in accordance with Sec.  175.10(a)(4) have their release 
devices protected by a cap or other suitable means.
--A grandfather provision to allow the shipment of materials classified 
as corrosive to steel or aluminum under ASTM G 31-72.
-- A provision to require that the word ``overpack'' be marked on 
overpacks to indicate that inside packages comply with prescribed 
specifications.
--An amendment to the criteria for classification of materials that are 
corrosive to metals.
--Revision of the limited quantity provisions for Class 6.1, PG II 
materials and for materials with a subsidiary hazard of 6.1, PG II.
--Amendments to the packaging requirements for materials classified as 
Division 6.1, Packing Group I, Hazard Zone A or Hazard Zone B.
--Revision of the organic peroxide packaging requirements in order to 
have one consolidated packaging section for organic peroxides. The 
revised section will include three separate tables for organic 
peroxides authorized for transport in non-bulk packagings, IBCs, and 
bulk packagings other than IBCs, respectively. Additionally, the 
packaging tables will be updated through the amendments to the organic 
peroxide requirements that will add, revise, or delete certain entries 
in the organic peroxide tables.

III. Overview of Amendments Not Being Considered for Adoption in This 
Final Rule

    This final rule makes changes to the HMR based on amendments to the 
Thirteenth Revised Edition of the UN Recommendations, Amendment 32 to 
the IMDG Code, and the 2005-2006 ICAO Technical Instructions, which 
become effective January 1, 2005. However, we are not adopting all of 
the amendments to those documents into the HMR. In many cases, 
amendments to the international regulation have not been adopted 
because of the framework or structure of the HMR. In several cases, we 
are handling certain amendments in separate rulemakings. For example, 
all amendments related to infectious substances are being handled under 
Docket HM-226A. In some instances, such as the amendment to ICAO 
Technical Instructions to allow certain oxygen generators aboard 
passenger carrying aircraft, we do not believe the amendment to be in 
the interest of public safety.
    One of the goals of this rulemaking is to continue to maintain 
consistency between the HMR and the international requirements. We are 
not striving to make the HMR identical to the international regulations 
but rather striving to remove or avoid potential barriers to 
international transportation.
    Below is a listing of those significant amendments to the 
international regulations that we have not included in this final rule 
with a brief explanation of why the amendment was not included:
     Requirements for infectious substances and genetically 
modified micro-organisms;
    [Amendments to the HMR related to infectious substances will be 
addressed in a future rulemaking under Docket HM-226A. Several other 
federal agencies regulate genetically modified micro-organisms; thus we 
do not plan to adopt provisions for their transport in the HMR.]
     Compressed gas cylinders;
    [Amendments to the HMR related to compressed gas cylinders will be 
addressed in a future rulemaking under Docket HM-220E.]
     Environmentally hazardous substances;
    [Delay in action pending further amendments to the international 
regulations.]
     Hazardous materials security;
    [Amendments to the HMR related to the UN Model Regulation's 
hazardous materials security requirements were promulgated in a 
rulemaking under the HM-232 Docket series.]
     Requirements for radioactive materials;
    [Amendments to the HMR related to Class 7 (radioactive) materials 
are being addressed in a rulemaking under the HM-230 Docket series.]
     Non-specification bulk packagings;
    [We are not adopting the new requirements in the UN Recommendations 
for non-specification bulk packagings including the additional 
inspection, testing and marking requirements. We are unsure about the 
cost impacts of imposing these additional amendments and, therefore, 
are not adopting any additional amendments at this time.]
     The reference to EN 10028-3, Part 3 for defining steel 
grain size relevant to the definition of fine grain steel;
    [We do not believe there is a need to adopt the European standard 
EN 10028-3, Part 3 because this standard is equivalent to ASTM E 112-96 
(IBR, see Sec.  171.7 of this subchapter). In addition, the ASTM 
standard is currently referenced in the HMR and is more commonly used 
and recognized in the U.S.]
     Bulk authorization for UN0331, UN0332 and UN3375;
    [For several years, we have authorized, under exemption, the 
transport of certain blasting agents in bulk packagings. We are 
currently reviewing those exemptions to determine if they should be 
included in the HMR. The amendments in the UN Recommendations related 
to the bulk authorizations for UN0331, UN0332 and UN3375 will be 
included in that review.]
     The removal of wooden barrel requirements;
    [The removal of the wooden barrel requirements (2C1 and 2C2) may be 
considered in a future rulemaking.]
     The 24-hour gasket relaxation requirement;
    [A requirement that removable head packagings for liquids not be 
drop tested until at least 24 hours after filling and closing to allow 
for any possible gasket relaxation was adopted in the thirteenth 
revised edition of the UN Model Regulations. We have conducted testing 
in coordination with drum manufacturers and have determined that this 
requirement is not substantiated by the results of the tests conducted. 
Therefore, we are not adopting into the HMR amendments relative to the 
24-hour gasket relaxation requirement. We also opposed this requirement 
when it was considered by the UN TDG Sub-Committee.]
     Authorization to transport protective breathing equipment 
(PBE's) with an oxygen generator as cargo onboard a passenger-carrying 
aircraft.
    [We do not believe that oxygen generators should be transported 
aboard passenger carrying aircraft. Therefore, we are not adopting the 
ICAO amendment that would allow oxygen generators in protective 
breathing equipment to be transported in passenger carrying aircraft.]

IV. Section-By-Section Review

Part 171

Section 171.7

    Paragraph (a)(3) (incorporation by reference materials) is updated 
to include the most recent editions of the

[[Page 76046]]

ICAO Technical Instructions, the IMDG Code and the UN Recommendations. 
The updated editions of these standards become effective January 1, 
2005. Additionally, the International Maritime Organization (IMO) 
recommends authorizing a one-year transition period, with a delayed 
compliance date of January 1, 2006, for the use of the updated edition 
(Amendment 32) of the IMDG Code.
    The updated additions are as follows:

--The ICAO Technical Instructions, 2005-2006 Edition.
--The IMDG Code, Amendment 32.
--The UN Recommendations, Thirteenth Edition.
--The UN Manual of Tests and Criteria, 4th Revised Edition.

    Paragraph (b) (list of informational materials not requiring 
incorporation by reference) is revised by adding an additional 
reference for a new method for determining the size of an emergency-
relief device for portable tanks transporting organic peroxides. This 
revision is based on a petition for rulemaking numbered P-1428. The 
petition was submitted by the Organic Peroxides Producers Safety 
Division of the Society of the Plastics Industry, Inc.
    One commenter recommended that we revise the ``Note to Paragraph 
(h)(3)(vi)'' in Sec.  173.225 to maintain format consistency with the 
incorporation by reference entry for ``Example of a Test Method for 
Venting Sizing: OPPSD/SPI Methodology'' found in Sec.  171.7(a). We 
disagree. The reference to a second example of a test method for 
venting sizing is not found in Sec.  171.7(a) as a material 
incorporated by reference. Rather, it is found in Sec.  171.7(b) as 
informational material not requiring incorporation by reference. 
Therefore, for clarification we are revising Sec.  171.7(b) to include 
the reference to the ``American Institute of Chemical Engineers Process 
Safety Progress Journal.'' In addition, we are revising the ``Note to 
Paragraph (h)(3)(vi)'' in Sec.  173.225 to include a reference to Sec.  
171.7(b), list of informational materials not requiring incorporation 
by reference.

Section 171.8

    The definition for ``salvage packaging'' is revised to include the 
term ``non-conforming.'' The term ``non-conforming'' was added to the 
definition by the UN Committee of Experts in December 2000 to 
accommodate the use of salvage packaging for. Occasionally an undamaged 
package is found to be tested to a performance level which is less than 
that required for the specific substance it contains (e.g., a drum 
tested to PG II standards containing a PG I substance). In other 
instances, the package is found to be a non-performance tested 
packaging containing a regulated substance. In these situations, it may 
not be safe or practical to transfer the material to the correct 
packaging to continue on to the consignee in order to ensure compliance 
with the HMR. Therefore, the use of salvage packaging to contain ``non-
conforming'' packages will minimize the risk to those handling the 
package during its transport back to the shipper or to an appropriate 
disposal location.

Section 171.11

    Paragraph (d)(15) is revised to clarify that the limitations 
therein also apply to oxygen generators contained in personal breathing 
equipment. In addition, paragraph (d)(17) is revised to indicate that 
an organic peroxide that is not identified by a technical name in any 
of the organic peroxide tables found in Sec.  173.225 must be approved 
by the Associate Administrator in accordance with the requirements of 
Sec.  173.128(d).

Section 171.12

    In Sec.  171.12, paragraph (b)(20) is revised to indicate that an 
organic peroxide that is not identified by a technical name in any of 
the organic peroxide tables found in Sec.  173.225 must be approved by 
the Associate Administrator in accordance with the requirements of 
Sec.  173.128(d).

Section 171.12a

    Paragraph (a) is revised to clarify the requirements for the return 
to Canada of bulk packagings that correspond to DOT or UN 
Specifications. Paragraph (b)(9)(ii) is revised to indicate that the 
shipping certification must be completed for shipments from Canada that 
enter the U.S. Paragraph (b)(18) is revised to indicate that an organic 
peroxide that is not identified by a technical name in any of the 
organic peroxide tables found in Sec.  173.22 must be approved by the 
Associate Administrator in accordance with the requirements of Sec.  
173.128(d).

Section 171.14

    Paragraphs (d) and (d)(1) are revised to authorize a delayed 
implementation date for the amendments in this final rule. The 
effective date of this final rule is January 1, 2005. We are also, 
authorizing a delayed compliance date of January 1, 2006, which is 
comparable to the transitional provisions provided in the final rule 
published under Docket HM-215E. The delayed mandatory compliance date 
offers sufficient time to implement the new requirements.
    Paragraph (d)(2) is revised to authorize certain intermixing of old 
and new requirements.

Part 172

Section 172.101

    The regulatory text preceding the Hazardous Materials Table is 
revised as follows:
    Paragraph (c)(11) and the corresponding note to paragraph (c)(11) 
are amended to revise a section reference. The reference to Sec.  
173.225(c) in the first sentence is revised to read Sec.  173.225(b) 
and the reference to Sec.  173.225(c)(2) in the note to paragraph 
(c)(11) is revised to read Sec.  173.225(b)(2).
    Paragraph (d)(4) is revised by adding a statement indicating that 
when the abbreviation ``Comb liq.'' is found in the ``Hazard class or 
division'' column of the Hazardous Materials Table (column 3), the 
material falls into the ``Combustible liquid'' hazard class.
    Paragraph (i)(3) of this section is revised to specify that Column 
7 of the Hazardous Materials Table contains additional bulk packaging 
authorizations and limitations for the use of UN portable tanks.
    Sec.  172.101 The Hazardous Materials Table (HMT). In this final 
rule we made various amendments to the HMT. Readers should review all 
changes for a complete understanding of the Table amendments. The HMT 
has been reprinted in its entirety due to the numerous changes. Under 
this final rule the changes to the HMT for the purpose of harmonizing 
with international standards, unless otherwise stated, include, but are 
not limited to the following:
     We revised several entries by adding the qualifying word 
``liquid.'' This action is consistent with the revisions to proper 
shipping names that were incorporated into the Thirteenth Revised 
Edition of the UN Recommendations. Affected entries are as follows:

UN1392 Alkaline earth metal amalgam
UN1420 Potassium metal alloys
UN1422 Potassium sodium alloys
UN1701 Xylyl bromide
UN1742 Boron trifluoride acetic acid complex
UN1743 Boron trifluoride propionic acid complex
UN2235 Chlorobenzyl chlorides
UN2236 3-Chloro-4-methylphenyl isocyanate
UN2306 Nitrobenzotrifluorides
UN2445 Lithium alkyls
UN2552 Hexafluoroacetone hydrate
UN2937 alpha-Methylbenzyl alcohol

[[Page 76047]]

UN3276 Nitriles, toxic, n.o.s.
UN3278 Organophosphorus compound, toxic, n.o.s.
UN3280 Organoarsenic compound, n.o.s.
UN3282 Organometallic compound, toxic, n.o.s.
UN3281 Metal carbonyls, n.o.s.

     We revised several entries by adding the qualifying word 
``solid.'' This action is consistent with the revisions to proper 
shipping names that were incorporated into the Thirteenth Revised 
Edition of the UN Recommendations. Affected entries are as follows:

UN1445 Barium chlorate
UN1447 Barium perchlorate
UN1459 Chlorate and magnesium chloride mixture
UN1470 Lead perchlorate
UN1578 Chloronitrobenzenes
UN1579 4-Chloro-o-toluidine hydrochloride
UN1650 beta-Naphthylamine
UN1680 Potassium cyanide
UN1689 Sodium cyanide
UN1690 Sodium fluoride
UN1697 Chloroacetophenone
UN1709 2,4-Toluylenediamine
UN1812 Potassium fluoride
UN1843 Ammonium dinitro-o-cresolate
UN2074 Acrylamide
UN2239 Chlorotoluidines
UN2261 Xylenols
UN2446 Nitrocresols
UN2662 Hydroquinone
UN3283 Selenium compound, n.o.s.

     We revised several entries by removing the qualifying word 
``solid.'' This action provides consistency with the Thirteenth Revised 
Edition of the UN Recommendations. The affected entries are as follows:

UN1489 Potassium perchlorate, solid
UN1598 Dinitro-o-cresol, solid
UN1638 Mercury iodide, solid
UN1740 Hydrogendifluorides, n.o.s. solid
UN2439 Sodium hydrogendifluoride, solid

     We deleted several entries. This action removes from the 
HMR the solution form of entries that are not identified as solutions 
in the Thirteenth Revised Edition of the UN Recommendations. The 
deleted entries are as follows:

UN1489 Potassium perchlorate, solution
UN1598 Dinitro-o-cresol, solution
UN1638 Mercury iodide, solution
UN1740 Hydrogendifluorides, n.o.s. solutions
UN2439 Sodium hydrogendifluoride solution
     We revised the proper shipping name ``Butadienes, 
stabilized,'' UN1010 to read ``Butadienes, stabilized or Butadienes and 
hydrocarbon mixture, stabilized, containing more than 40% butadienes.''
     We revised the proper shipping name ``Potassium 
hydrogendifluoride, solid,'' UN1811 to read ``Potassium 
hydrogendifluoride, solid.''
     We revised the proper shipping name ``Refrigerating 
machines, containing non-flammable, non-toxic, liquefied gas or ammonia 
solution (UN2672),'' UN2857 to read ``Refrigerating machines containing 
non-flammable, non-toxic gases or ammonia solutions (UN2672).''
     We removed four references to IB52 and four references to 
T23 from column 7 of the HMT. This change is necessary because IB52 and 
T23 have been relocated to Sec.  173.225. The affected entries are:

UN3109 Organic peroxide type F, liquid
UN3110 Organic peroxide type F, solid
UN3119 Organic peroxide type F, liquid, temperature controlled
UN3120 Organic peroxide type F, solid, temperature controlled

     IP5 is removed from column 7 of the HMT for the following 
UN entries:

UN1791 Hypochlorite solution
UN2014 Hydrogen peroxide, aqueous solution with not less than 20% but 
not more than 60% hydrogen peroxide (stabilized as necessary).
UN3149 Hydrogen peroxide and peroxyacetic acid mixture with acid(s), 
water and not more than 5% peroxyacetic acid.

     We deleted several entries. This action is consistent with 
the deletion of proper shipping names that were incorporated into the 
Thirteenth Revised Edition of the UN Recommendations that we are 
proposing to adopt into the HMR. The entries affected are:

UN2003 Metal alkyls, water-reactive, n.o.s. or Metal aryls, water-
reactive, n.o.s.
UN3049 Metal alkyl halides, water-reactive, n.o.s. or Metal aryl 
halides, water-reactive, n.o.s.
UN3050 Metal alkyl hydrides, water-reactive, n.o.s. or Metal aryl 
hydrides, water-reactive, n.o.s.
UN3207 Organometallic compound or Compound solution or Compound 
dispersion, water-reactive, flammable, n.o.s.
UN3203 Pyrophoric organometallic compound, water-reactive, n.o.s., 
liquid Pyrophoric organometallic compound, water-reactive, n.o.s., 
solid
UN3372 Organometallic compound, solid, water-reactive, flammable, 
n.o.s.

     We added the following new entries. Many of these entries 
are the liquid or solid form of entries that are already listed in the 
HMT. This action is consistent with the addition of proper shipping 
names that were incorporated into the Thirteenth Revised Edition of the 
UN Recommendations. The new entries are as follows:

UN3377 Sodium perborate monohydrate
UN3378 Sodium carbonate peroxyhydrate
UN3379 Desensitized explosives, liquid, n.o.s.
UN3380 Desensitized explosives, solid, n.o.s.

UN3468 Hydrogen in a metal hydride storage system

    A commenter stated that by adding the shipping names for 
desensitized explosives under identification numbers UN3379 and UN3380, 
approvals should be modified to authorize the use of classifications 
for the applicable hazardous materials. The commenter also noted that 
due to these additions, the definitions for flammable solids and 
flammable liquids require revision to account for the new shipping 
names. We do not anticipate a significant number of explosives being 
assigned to these shipping names. Therefore, we disagree with the 
commenter's contention that each holder of an EX number request an 
updated shipping classification. In addition, we do not agree with the 
commenter's request to revise the definitions of flammable solid and 
flammable liquid to include the additional proper shipping names. The 
definitions of flammable solid and flammable liquid adequately describe 
materials assigned to those shipping names. Additionally, shipping 
names are not found under hazard class definitions, but rather, in the 
HMT.
     We added the following new generic entries for materials 
that are toxic by inhalation. These new names will replace the existing 
generic entries in the HMT. This action is consistent with the addition 
of proper shipping names that were incorporated into the Thirteenth 
Revised Edition of the UN Recommendations. Affected entries are as 
follows:

UN3381 Toxic by inhalation liquid, n.o.s. with an inhalation toxicity 
lower than or equal to 200 ml/m\3\ and saturated vapor concentration 
greater than or equal to 500 LC50.
UN3382 Toxic by inhalation liquid, n.o.s. with an inhalation toxicity 
lower than or equal to 1000 ml/m\3\ and saturated vapor concentration 
greater than or equal to 10 LC50.
UN3383 Toxic by inhalation liquid, flammable, n.o.s. with an inhalation 
toxicity lower than or equal to 200 ml/m\3\ and saturated vapor 
concentration greater than or equal to 500 LC50.
UN3384 Toxic by inhalation liquid, flammable, n.o.s. with an inhalation 
toxicity lower than or equal to 1000 ml/m\3\ and saturated vapor 
concentration greater than or equal to 10 LC50.
UN3385 Toxic by inhalation liquid, water-reactive, n.o.s. with an 
inhalation toxicity lower than or equal to 200 ml/m\3\ and saturated 
vapor concentration greater than or equal to 500 LC50.
UN3386 Toxic by inhalation liquid, water-reactive, n.o.s. with an 
inhalation toxicity lower than or equal to 1000 ml/m\3\ and saturated 
vapor concentration greater than or equal to 10 LC50.
UN3387 Toxic by inhalation liquid, oxidizing, n.o.s. with an inhalation 
toxicity lower than or equal to 200 ml/m\3\ and saturated vapor 
concentration greater than or equal to 500 LC50.
UN3388 Toxic by inhalation liquid, oxidizing, n.o.s. with an inhalation 
toxicity lower than or equal to 1000 ml/m\3\ and saturated vapor 
concentration greater than or equal to 10 LC50.
UN3389 Toxic by inhalation liquid, corrosive, n.o.s. with an inhalation 
toxicity lower than or equal to 200 ml/m\3\ and saturated vapor 
concentration greater than or equal to 500 LC50.
UN3390 Toxic by inhalation liquid, corrosive, n.o.s. with an inhalation 
toxicity lower than or equal to 1000 ml/m\3\ and saturated vapor 
concentration greater than or equal to 10 LC50.

     We added the following new generic entries for 
organometallic substances. This action is consistent with the addition 
of proper shipping names that were incorporated into the Thirteenth 
Revised Edition of the UN Recommendations. The new entries are as 
follows:

UN3391 Organometallic substance, solid, pyrophoric
UN3392 Organometallic substance, liquid, pyrophoric
UN3393 Organometallic substance, solid, pyrophoric, water-reactive
UN3394 Organometallic substance, liquid, pyrophoric, water-reactive
UN3395 Organometallic substance, solid, water-reactive
UN3396 Organometallic substance, solid, water-reactive, flammable
UN3397 Organometallic substance, solid, water-reactive, self-heating
UN3398 Organometallic substance, liquid, water-reactive
UN3399 Organometallic substance, liquid, water-reactive, flammable
UN3400 Organometallic substance, solid, self-heating

    In addition, we are continuing to allow the use of the following 
specific Organometallic entries: UN1366, UN1370, UN2005, UN2445, 
UN3051, UN3052, UN3053, and UN3076. However, we anticipate removing 
these entries from the HMT by January 1, 2007.
     The U.N. Recommendations have adopted a rationalized 
approach for the assignment of UN portable tank instructions for solid 
materials. Based on that rationalized approach, we made several changes 
to UN portable tank authorizations in the HMR. These changes are 
summarized as follows. For a more specific identification of the 
affected shipping descriptions, refer to the UN report located in the 
public Docket.
    For Division 4.1, Packing Group I materials, the use of UN portable 
tanks is not authorized.
    For Division 4.3 materials with a subsidiary class of 6.1, in 
Packing Group I, the use of portable tanks is not authorized.
    For materials of Divisions 4.1, 4.2, 4.3, 5.1, 6.1, and Classes 8 
and 9, in Packing Group II, Special Provisions T3 is specified.
    For Division 4.2, Packing Group I materials, T21 and TP7 is 
specified.
    For Division 4.3, Packing Group I materials, T9 and TP7 is 
specified.
    For Division 5.1, Packing Group I materials, the use of UN portable 
tanks is not authorized.
    For Division 6.1 and Class 8, Packing Group I materials, T6 is 
specified.
    For materials of Divisions 4.1, 4.2, 4.3, 5.1, 6.1, and Classes 8 
and 9, in Packing Group III, Special Provisions T1 is specified.

[[Page 76049]]

     Several entries in the HMT have been revised by amending 
column 9B to read ``forbidden'' so that the materials are no longer 
authorized for transport aboard cargo aircraft. The entries have been 
revised because they meet the criteria of either Zone C or Zone D 
inhalation toxicity. All other Zone C and Zone D toxic by inhalation 
materials listed in the HMR are currently already forbidden from 
transport aboard passenger and cargo aircraft (these materials are 
already forbidden from transport aboard passenger aircraft). The 
entries to be revised include:
Zone C
UN2204 Carbonyl sulfide
UN1023 Coal gas, compressed
UN1064 Methyl mercaptan
UN1048 Hydrogen bromide, anhydrous
UN1079 Sulfur dioxide
Zone D
UN1005 Ammonia, anhydrous
UN3318 Ammonia solution, relative density less than 0.880 at 15 degrees 
C in water, with more than 50 percent ammonia
UN1040 Ethylene oxide or Ethylene oxide with nitrogen up to a total 
pressure of 1MPa (10 bar) at 50 degrees C
UN1040 Ethylene oxide or Ethylene oxide with nitrogen up to a total 
pressure of 1MPa (10 bar) at 50 degrees C
UN2191 Sulfuryl fluoride

    Also, see Sec.  172.102 for additional HMT amendments.

Appendix B to Sec.  172.101

    In Appendix B to Sec.  172.101, List of Marine Pollutants, we 
removed the entries ``Diphenyl oxide and biphenyl phenyl ether 
mixtures,'' ``Isoamyl mercaptan,'' ``Pentanethiols,'' and 
``Tetrachlorophenol.'' We revised the entry ``2, 6-Di-tert-
Butylphenol'' and we added the entry ``Chloropicrin.''

Section 172.102

    We amended Sec.  172.102, Special Provisions, as follows:
     Several entries in the HMT are revised by adding special 
provisions A3, A6, A7, A9, A10, N3, and N36 to align this section with 
the equivalent special provisions in the ICAO Technical Instructions 
(13, 2, 5, 4, 7, 21, and 3 respectively). We removed the ``A'' special 
provisions for several entries because we have determined that the 
materials to which the provisions apply are currently not authorized 
for transportation on either passenger or cargo aircraft.
    The following entries are revised by adding special provision A3:

UN1154 Diethylamine

     The following entries are revised by removing certain 
``A'' special provisions since the materials themselves are forbidden 
for transportation aboard passenger and cargo aircraft:

     Paragraph (b)(3) of this section is amended to specify 
that a ``B'' code refers to a special provision that applies only to 
certain bulk packaging requirements and that, unless otherwise stated, 
does not apply to UN, IM Specification portable tanks or IBCs.
     Paragraph (b)(4) of this section is amended to specify 
that a code containing the letters ``IB'' or ``IP'' refers to a special 
provision that applies only to transportation in IBCs.
     Paragraph (b)(7) of this section is amended to specify 
that a code containing the letter ``T'' refers to a special provision 
which applies only to transportation in UN or IM Specification portable 
tanks.
     Paragraph (b)(8) is redesignated (b)(9) and a new 
paragraph (b)(8) is added to specify that a code containing the letters 
``TP'' refers to a special provision that is in addition to those 
provided by the portable tank instructions or the requirements in part 
178.
     Special Provision 47 is revised to include an additional 
exception currently in the UN Model Regulations specifying that a 
leakproofness test is not required when the liquids are fully absorbed 
in solid material contained in sealed bags.
     Special Provision 135 is revised to expand the 
applicability of the proper shipping names ``Vehicle, flammable liquid 
powered'' and ``Vehicle, flammable gas powered'' to include hybrid 
electric vehicles.
     Special Provision 137 is revised to expand the exception 
for ``Cotton, dry''.
     Special Provision 143 is removed and relocated to Sec.  
173.219 so that the limitations on the types of hazardous materials 
authorized apply to both self-inflating and non-self-inflating life-
saving appliances.
     Special Provision 153 is relocated to new paragraph (k) in 
Sec.  173.115 and revised to include amended classification criteria 
for aerosols containing flammable constituents consistent with criteria 
in the UN Model Regulations. The revised criteria include methods for 
the classification of aerosols based on the percentage of flammable 
components. One commenter agreed with the removal of Special Provision 
153 and the relocation of classification criteria for aerosols to Sec.  
173.115(k).
     New Special Provision 163 is added to specify that 
Ammonium Nitrate Emulsions are required to satisfactorily pass Test 
Series 8 of the UN Manual of Tests and Criteria, Part I, Section 18.
     New Special Provision 164 is added to specify that an 
approval is required for ``Desensitized explosives, liquid, n.o.s.'' 
and ``Desensitized explosives, solid, n.o.s.''
     New Special Provision 165 is added to the calcium 
hypochlorite PG II and the PG III entries for UN1748 and UN2880 to 
specify the danger of exothermic decomposition and require shading from 
direct sunlight and sources of heat during transportation. One 
commenter agreed with our efforts to harmonize the HMR with UN 
Recommendations, but was concerned with the intent of Special Provision 
165. This commenter agreed that calcium hypochlorite should be shaded 
from direct sunlight but questioned the ambient heat and ventilation 
provisions. The commenter stated that calcium hypochlorite is currently 
transported in closed cargo transport units, thus, satisfying the 
requirement to protect this hazardous material from direct sunlight. 
However, since the cargo transport units are not ventilated by fan or 
induced ventilation, and the cargo transport units would be subjected 
to ambient heat, a violation of Special Provision 165 appears imminent. 
We disagree. We feel Special Provision 165 provides latitude for 
compliance with the ventilation and ambient heat requirements. Proper 
ventilation and protection from ambient heat can be achieved during the 
loading process of the cargo transport units and throughout the 
transportation cycle by allowing adequate space for air movement around 
the calcium hypochlorite packages. We do agree; however, that cargo 
transport units themselves should not be required to be shaded from 
direct sunlight. Therefore, we have revised the regulatory text 
accordingly.
     New Special Provision 166 is added to the PG II entry for 
calcium hypochlorite, UN2880 and UN1748 to indicate that calcium 
hypochlorite in the non-friable tablet form may be transported as a PG 
III material.
     New Special Provision 167 is added to the new entry for 
``Hydrogen in a metal hydride storage system'' to specify that such 
storage systems shall always be considered as containing hydrogen.
     New Special Provision 170 is added to Organometallic 
substances entries (UN3391, UN3392, UN3393, and UN3394). The special 
provision requires air to be eliminated from the vapor space by 
nitrogen or other means.
     New Special Provision 171 is added to the UN2880 PG III 
entry. Since UN2880 also covers mixtures of hydrated calcium 
hypochlorite in any concentration, some formulations in other than 
tablet form (e.g., in granular form) may meet the criteria for 
classification in Division 5.1, Packing Group III when subjected to the 
relevant test in the UN Manual of Tests and Criteria. The PG III entry 
for calcium hypochlorite is only authorized when the material is 
offered in the non-friable tablet form or for granular or powdered

[[Page 76051]]

mixtures. This entry is not authorized for the pure form of ``Calcium 
hypochlorite, hydrated''. We also recognize that some formulations, 
when tested, do not meet the criteria for classification in Division 
5.1. In light of this, we added a new Special Provision 171 to the 
UN2880, PG III entry in the HMT to allow for the possibility to 
classify powdered or granular mixtures of hydrated calcium hypochlorite 
in Packing Group III when data indicate that the mixture meets the 
criteria for assignment to PG III. One commenter supports the revisions 
that align calcium hypochlorite entries in the HMT with UN 
Recommendations. However, this commenter requested the addition of 
Special Provision 171 to the entry, ``Calcium hypochlorite, dry or 
Calcium hypochlorite mixtures dry, (UN1748)'' for consistent alignment 
with the UN Recommendations. We agree. After further review of the UN 
Recommendations, we have determined that the UN Special Provision 316 
is equivalent to the proposed Special Provision 171 in Docket HM-215G, 
and is applicable to both the ``dry'' and ``hydrated'' calcium 
hypochlorite entries. Therefore, we are assigning Special Provision 171 
to the ``Calcium hypochlorite, dry or Calcium hypochlorite mixtures 
dry, (UN1748)'' entry.
     Special Provision A11 is currently assigned to UN 2983, 
Ethylene oxide and Propylene oxide mixtures and UN 1411, Lithium 
aluminum hydride, ethereal. In the ICAO Technical Instructions these 
substances are only authorized for transport in metal cylinders. A11 
states ``For combination packagings, when metal inner packagings are 
permitted, only specification cylinders constructed of metals which are 
compatible with the hazardous material may be used. In the NPRM, we 
proposed to harmonize with the applicable ICAO Technical Instruction 
particular packing requirement (PPR 8), however discussions with the 
ICAO Dangerous Goods Panel and further analysis of ICAO PPR 8 has 
revealed that the requirement may need to be amended. Our analysis 
showed that other packagings, including glass inner packagings, are 
authorized, and as such restricting packagings to only specification 
cylinders appears unnecessarily restrictive. As such we are not 
proposing to amend Special Provision A11 in this final rule.
     Consistent with ICAO, we are adding a proper shipping name 
to the HMT for ``Receptacles, small containing gas, 2.2 with a 
subsidiary of 5.1.'' A new ``A'' code (A14) is added to prohibit this 
material from being transported as a limited quantity or consumer 
commodity in accordance with Sec.  173.306 aboard an aircraft. This new 
``A'' code has also been added to the following additional shipping 
names: ``Oxygen, compressed,'' Carbon dioxide and oxygen mixtures,'' 
``Nitrous oxide'', ``Compressed gas oxidizing,'' and ``Liquefied gas, 
oxidizing.''
     For consistency, the authorization in Special Provision 
B69 to allow dry sodium or potassium cyanide in siftproof, water-
resistant fiberboard IBCs is relocated to new Special Provision IP20.
     Paragraph (c)(4) of this section is amended by relocating 
``Table 2.--Organic Peroxide IBC Code (IB52)'' to paragraph (e) of 
Sec.  173.225 and renaming it the ``Organic Peroxide IBC Table.'' Table 
3.--IP Codes is redesignated Table 2.--IP Codes. The wording of 
paragraph (c)(4) is revised to indicate that Table 3.--IP Codes had 
been redesignated Table 2.--IP Codes. All references to IB52 in the HMR 
are removed and replaced with ``Organic Peroxide IBC Table'' or ``Sec.  
173.225(e),'' as applicable.
     Paragraph (c)(7) is amended by relocating the Portable 
Tank Code T50 Table to Sec.  173.313 and renaming it ``UN Portable Tank 
Table for Liquefied Compressed Gases.'' The T50 Table and its 
description is removed from paragraph (c)(7)(iv) and replaced with a 
statement indicating that the new ``UN Portable Tank Table for 
Liquefied Compressed Gases'' is found in Sec.  173.313. All references 
to T50 in the HMR are removed and replaced with ``UN Portable Tank 
Table for Liquefied Compressed Gases in Sec.  173.313.'' In addition, 
paragraph (c)(7) is amended by relocating Portable Tank Code T23 to 
paragraph (g) of Sec.  173.225 and renaming it the ``Organic Peroxide 
Portable Tank Table.'' Portable Tank Code T23 and its description found 
in paragraph (c)(7)(iii) are removed and paragraphs (c)(7)(iv)-
(c)(7)(vii) are redesignated (c)(7)(iii)-(c)(7)(vi), respectively. All 
references to T23 in the HMR are removed and replaced with ``Organic 
Peroxide Portable Tank Table'' or ``Sec.  173.225(g),'' as applicable.
     New paragraph (c)(8) is added to provide an introduction 
to the ``TP'' codes (i.e., portable tank special provisions). The 
existing paragraph (c)(8) is redesignated paragraph (c)(9).
     New Special IBC Packing Provision IP13 is added to specify 
that transportation by vessel in IBCs is prohibited.
     New Special IBC Packing Provision IP14 is added to specify 
that air must be eliminated from the vapor space by nitrogen purging or 
other means.
     New Special IBC Packing Provision IP20 is added to specify 
that dry sodium cyanide and potassium cyanide are also permitted in 
siftproof, water-resistant, fiberboard IBCs when transported in closed 
freight containers or transport vehicles.
     Portable tank Special Provision TP3 is revised to include 
the maximum degree of filling (in %) for solids transported above their 
melting points.
     Special Provision TP6 is revised by removing the word 
``event'' and replacing it with the word ``incident.''
     Portable tank Special Provision TP9 is removed from column 
(7) of the HMT for all materials that reference a T code special 
provision. Special provision TP9 states that a material with TP9 in 
Column (7) may only be transported in a portable tank if approved by 
the Associate Administrator. A material that has been given a T code 
does not require approval and is not subject to Special Provision TP9.
     In the NPRM we proposed adoption of a new portable tank 
special provision, TP33, by adding the new provision to certain entries 
in the HMT. However, we neglected to include the text of the provision 
itself. We are correcting this omission in this final rule.

Section 172.202

    We are editorially revising paragraph (a)(2)(iii) by removing the 
examples that illustrate the optional provision to enter primary and 
subsidiary hazard class or division names on shipping papers for 
domestic shipments. In the HM-215E response to appeals final rule (69 
FR 34604) that was published on June 22, 2004, we reinstated the 
provision which was removed in a previous rulemaking (68 FR 44992). 
During the process of correcting a printing error in one of the 
examples, we determined that the regulatory text is complete and 
sufficient without the use of examples.
    In the NPRM [69 FR 34741] we proposed to amend paragraph (a)(5)(i) 
to require the quantity shown on a shipping paper for an explosive 
article, such as Cartridges, small arms, to be the net mass of the 
entire article rather than the net mass of the explosive contained in 
the article. Commenters generally support the proposal, suggesting that 
it will provide for consistency across modes of transportation and for 
more accurate calculations. However, several of these commenters note 
that, for certain explosive articles that contain very small amounts of 
an explosive, showing the net mass of the article rather than of the 
explosive contained in the article could misrepresent the 
transportation risk associated with the article. Two commenters state 
that,

[[Page 76052]]

because shippers have historically calculated the net mass based on the 
actual explosive material contained in the article rather than the 
entire article, the clarification proposed in the NPRM could cause 
increased confusion for shippers.
    Internationally, as well, there is some concern that, at least for 
large explosive articles, the quantity indicated on the shipping paper 
should be the net mass of the explosive substances contained in the 
article rather than the net mass of the article itself. As suggested by 
some commenters to the NPRM, a number of the members of UN Transport of 
Dangerous Goods Sub-Committee agree using the net mass of the entire 
article rather than the net mass of the explosive material contained in 
the article may not appropriately communicate the explosive hazard to 
emergency responders. Until this issue is resolved through a change to 
the UN Model Recommendations, we are, in this final rule, amending 
paragraph (a)(5)(i) to clarify that for explosive articles the quantity 
shown on a shipping paper may be expressed in terms of the net mass of 
the article or the net mass of the explosive substances contained in 
the article. It should be noted, however, that for purposes of 
determining the per-package quantity limitations shown in Column 9 of 
the HMT, Sec.  172.101(j)(3) specifies that when articles or devices 
are specifically listed by name, the net quantity limitation applies to 
the entire article or device rather than to its hazardous components. 
This would include explosive articles listed by name in the HMT. For 
example, in the case of a listed explosive article weighing 15 kg and 
containing 500 grams of explosive substance, the weight shown on the 
shipping paper may be 500 grams or 15 kg, but the weight used for 
purposes of compliance with Column (9) of the HMT must be 15 kg as 
required by Sec.  172.101(j)(3).
    Particularly for large articles, the quantity indicated on the 
shipping paper should be the net mass of the explosive substances 
contained in the article. For small explosive articles, such as 
Cartridges, small arms, we believe that the net mass of the article can 
be used to satisfy the total quantity requirement in Sec.  
172.202(a)(5)(i). As a practical matter, it is easier, and in certain 
instances necessary, for an offeror to provide the net mass of the 
article and the net explosive mass. For example, as previously stated, 
the net mass of an article must be used to ensure compliance with the 
per package quantity limitations set forth in Column 9 of the Sec.  
172.101 Hazardous Materials Table for transport aboard aircraft or 
passenger rail (see Sec.  172.101(j)(3)). However, for operational 
purposes, such as for stowage and segregation of large quantities of 
explosives or determining the quantity of explosives that can be 
transported on a vessel [see Sec.  176.142(b)], the net explosive mass 
of the explosive substances contained in articles is needed.

Section 172.203

    Paragraph (f) is revised by including the passenger and cargo 
aircraft limitation certification statement that is found in Sec.  
172.204. This aligns the HMR with the ICAO TI (see 4.1.5.8.1(b) of the 
ICAO TI). A new paragraph (i)(3) is added to specify additional 
shipping paper description requirements for a hazardous material 
consigned under an ``n.o.s.'' entry when offered for transportation by 
vessel. In addition, paragraph (m)(2) is revised to specify that the 
phrase ``Poison Inhalation Hazard'' or ``Toxic Inhalation Hazard'' is 
not required to be repeated if it otherwise appears in the shipping 
description. Finally, in paragraph (o)(3), the reference to Sec.  
173.225(c)(2) is amended to read Sec.  173.225(b)(2).
    One commenter felt the requirement to add a segregation code on the 
shipping paper for ``n.o.s.'' entries is unnecessary and unduly 
burdensome. In addition, the commenter is concerned that there may not 
be sufficient space on the shipping paper to indicate this notation. 
If, however, this requirement is adopted, the commenter requested an 
example of the required entry on shipping papers. We disagree. We do 
not feel this additional requirement is unnecessary or overly 
burdensome. The additional shipping paper description requirements 
apply only to hazardous material consigned under an ``n.o.s.'' entry 
when offered for transportation by vessel. We believe that consignors 
should be familiar with the hazards and segregation risks of their 
shipments, specifically ``n.o.s.'' materials that are not assigned 
segregation groups. By indicating the need to segregate such materials 
on the shipping paper, the consignor increases the likelihood that 
appropriate stowage procedures are followed, ensuring the safety of the 
vessel and its cargo. We also do not agree that there is inadequate 
space available on shipping papers to include the segregation group. 
However, we do agree that an example of the required entry should be 
presented for clarity and uniformity. Therefore, as recommended by the 
commenter, we are adding the example ``IMDG Code segregation group--1 
Acids'' to Sec.  172.203.

Section 172.204 and Section 172.321--Air Eligibility Marking

    Under HM-215E (68 FR 44992), the air eligibility marking was 
adopted into the HMR as new Sec.  172.321. Since publication of that 
final rule, the ICAO's Dangerous Goods Panel removed the air 
eligibility marking requirement from the ICAO Technical Instructions. 
In lieu of this marking, ICAO adopted a requirement that the shipping 
paper certification statement include the statement ``I declare that 
all of the applicable air transport requirements have been met'' when a 
hazardous material is offered for air transportation. Additionally, the 
revised section provided examples of the applicable air transport 
requirements that must be met. Based on this action, we revised the air 
eligibility marking requirement by making it optional rather than 
mandatory and adding the additional shipping paper certification 
statement for shipments going by aircraft. Therefore, we revised Sec.  
172.204(c)(3) by requiring that the statement ``I declare that all of 
the applicable air transport requirements have been met'' be included 
on the shipping paper in addition to the current certification 
statement when a hazardous material is offered for air transportation. 
Additionally, the revised section provides examples of the applicable 
air transport requirements that must be met and various section 
references. In order to allow shippers to expend stocks of preprinted 
shipping papers containing the previous certification statement, we are 
providing an additional ten month transitional provision for the new 
certification statement. Two commenters support RSPA's decision 
requiring shippers to sign the certification declaring compliance with 
requirements for air transportation. Additionally, several commenters 
agree with the revision to make the air eligibility marking optional. 
However, some commenters suggest making the marking ``permissible'' 
instead of ``optional'' to avoid potential confusion. We disagree. We 
are removing the requirement for shippers to mark packages acceptable 
for air transport with the air eligibility marking. This revision does 
not prohibit the use of the marking.

Section 172.315

    Section 172.315 is amended to ensure that packages containing 
limited quantities which are transported by air are marked with the 
proper shipping name. Although the amendment was not proposed in this 
rulemaking, it was previously proposed and adopted under

[[Page 76053]]

HM-215E (68 FR 45000) but was omitted due to an editorial error during 
publication. The amendment provides harmonization with the ICAO 
Technical Instructions, which do not allow the UN number within a 
square-on-point border as a substitute for the proper shipping name. 
Note that this amendment does not preclude the ID number/square-on-
point border from appearing on a package transported by air, it simply 
ensures that the proper shipping name is also required.

Section 172.317

    A new Sec.  172.317 is added to require a ``KEEP AWAY FROM HEAT'' 
handling mark on packages containing self-reactive substances of 
Division 4.1 or organic peroxides of Division 5.2 when such packages 
are transported by air.

Part 173

Section 173.3

    The NPRM proposed to revise the requirements for use of salvage 
drums to include packages of hazardous materials that are found not to 
conform with the requirements of the HMR. In addition, the NPRM 
proposed to clarify that salvage drums may only be used for damaged, 
defective, non-conforming, or leaking packages identified as such after 
the packages have been placed in transportation. One commenter suggests 
that the phrase ``after having been placed in transportation'' as used 
in the NPRM is confusing and requests that we clarify the phrase using 
the terms ``pre-transportation functions'' and ``transportation 
functions'' as defined in a final rule published under Docket HM-223 
October 30, 2003 (68 FR 61905). In response to this comment, in this 
final rule, we modified Sec.  173.3(c) to clarify that salvage drums 
are to be used for damaged, defective, non-conforming, or leaking 
packages identified during transportation as ``transportation'' is 
defined in Sec.  5102(12) of Federal hazardous materials transportation 
law--that is, the movement of property and loading, unloading, or 
storage incidental to the movement. When the HM-223 final rule becomes 
effective, the statutory definition for ``transportation'' will be 
added to Sec.  171.8 of the HMR, as will definitions for ``movement,'' 
``loading incidental to movement,'' ``unloading incidental to 
movement,'' and ``storage incidental to movement.'' Note that a package 
found to be leaking prior to its being placed in transportation may not 
be packaged in a salvage drum. Instead, it must be repackaged into an 
authorized packaging in accordance with applicable HMR requirements.

Section 173.24

    For consistency with the UN Recommendations, paragraphs (g)(4) and 
(g)(5) are revised to clarify the following:
    (A) That IBCs (subject to the requirements in Sec.  173.24(g)) are 
permitted to be vented to reduce internal pressure; and
    (B) That venting of IBCs is not conditional upon whether a bulk 
special provision is indicated for a particular hazardous material in 
the Sec.  172.101 hazardous materials table.
    In addition, paragraph (i) is revised to clarify that other general 
requirements specific to air transportation apply and are found in 
Sec.  173.27.

Section 173.25

    Paragraph (a)(2) is revised by removing the requirement to mark an 
overpack with the air eligibility marking. In addition, in paragraph 
(a)(4), we are amending the HMR to require overpacks to be marked with 
the word ``OVERPACK'' or, alternatively, until October 1, 2007, with a 
statement indicating that inside packages comply with prescribed 
specifications. This is in response to adoption by the United Nations 
of the ``OVERPACK'' marking to indicate that packages within an 
overpack comply with prescribed specifications when specification 
markings on inside packagings within the overpack are not visible.

Section 173.27

    Paragraph (i) is revised to indicate that the air eligibility mark 
has been removed. This section references a new requirement for 
shippers to place the following statement at the end of the 
certification statement when a hazardous material is authorized for air 
transportation: ``I declare that all applicable air transport 
requirements have been met.''

Section 173.28

    In paragraph (c)(2), we deleted the words ``or a UN 1H1 plastic 
drum'' in order to harmonize the HMR with the UN Model Regulations and 
remove a source of confusion within the regulated community regarding 
the reconditioning of a non-bulk packaging.

Section 173.115

    In Sec.  173.115, a new paragraph (k) is added (see discussion 
under Sec.  172.102, Special Provision 153). One commenter noted that 
the proposed new Sec.  173.115(k) would not allow aerosols to contain 
corrosive substances of Packing Group II. The commenter further noted 
that UN Special Provision 63 allows aerosols to contain corrosive 
substances of Packing Group II and requested we harmonize with the UN 
Special Provision 63 in this regard. We agree with the commenter and 
further note that currently, the HMR authorizes a proper shipping name 
of ``Aerosols, corrosive Packing Group II or III, each not exceeding 1 
L capacity''. We are amending Sec.  173.115(k) accordingly to clarify 
that aerosols may contain corrosive substances of Packing Group II.

Section 173.120 and Appendix H to Part 173

    A commenter noted that under section Sec.  173.120(a)(3), the 
reference to Appendix H for sustained combustibility tests directs the 
reader to Figures 5.1 and 5.2 found in the UN Recommendations. These 
figures are no longer in the UN Recommendations, but, rather, are 
located in section 32.5.2 of the Fourth Revised Edition of the UN 
Manual of Tests and Criteria. We agree with the commenter. Therefore, 
we are amending Appendix H to Part 173 to reference the UN Manual of 
Tests and Criteria.

Section 173.128

    In paragraph (d)(1)(i), the section reference is revised to read 
Sec.  173.225(c). In addition, in paragraphs (d)(1)(ii) and 
(d)(1)(iii), the section reference is revised to read Sec.  173.225(b).

Section 173.132

    In paragraph (b)(1), we revised the definition of LD\50\ for acute 
oral toxicity to indicate that adult albino rats may be tested without 
regard to gender. The current definition for LD\50\ for acute oral 
toxicity in Sec.  173.132(b)(1) is based on the Organization for 
Economic Co-Operation and Development (OECD) Test Guideline (TG) 401. 
The OECD has agreed to three test methods that will replace the current 
TG 401. The United Kingdom, Germany and the United States of America 
took the lead in the development of the three alternative tests that 
OECD has now adopted and published in the OECD Guidelines for the 
Testing of Chemicals. In a continuing attempt to improve the estimate 
of acute oral toxicity while reducing the number of animals used per 
test, three alternative TGs have been developed and implemented to 
replace TG 401. The three TGs are the Fixed Dose Procedure (FDP, TG 
420), the Acute Toxic Class Method (ATCM, TG 423), and the Up-and-Down 
Procedure (UDP, TG 425). The text is consistent

[[Page 76054]]

with the text in the 13th revised edition of the UN Model Regulations.

Section 173.136

    We added a new paragraph (d) to provide a grandfather clause that 
will allow for the continued shipment of materials classified as 
corrosive to steel or aluminum under ASTM G 31-72 without retesting.

Section 173.137

    In paragraph (c)(2), we propose to eliminate the references to ASTM 
G 31-72 as an acceptable test description and add a statement 
indicating an acceptable test is prescribed in the Manual of Tests and 
Criteria, Part III, Section 37.

Sections 173.150, 173.151, 173.152, 173.153 and 173.154

    We are allowing most Division 6.1, Packing Group II materials to be 
transported under the limited quantity provisions when the packagings 
contain not more than 100 mL (3.38 ounces) each for liquids or 0.5 kg 
(1.1 pounds) each for solids. However, consistent with the limited 
quantity authorization for Division 6.1, Packing Group III, we are not 
providing a labeling exception for these materials. We are also not 
allowing these materials to be shipped as consumer commodities. In 
addition, we revised the limited quantity sections for the other hazard 
classes of materials to take into account materials with a subsidiary 
hazard of 6.1 Packing Group II. One commenter agreed with the amendment 
allowing numerous Class 3, PG II materials with Class 8 and other 
subsidiary hazards to be transported as limited quantities.

Section 173.185

    In Sec.  173.185, we amended paragraphs (c)(3) and (e)(6), to 
require those lithium cell and battery design types that are required 
to be subjected to the UN performance tests to be of a type that is 
proven to meet the requirements of the performance tests specified in 
the UN Manual of Tests and Criteria, Fourth Revised Edition. These 
cells and batteries are currently required to be of a type that is 
proven to meet the tests in the third revised edition. We also proposed 
a grandfather provision that would authorize a lithium cell or battery 
that was transported prior to the effective date of this rule that is 
of a type proven to meet the UN performance tests in the third revised 
edition to not be required to be retested in accordance with the tests 
in the fourth revised edition. One commenter supported this approach 
and stated that it is both necessary and appropriate to allow continued 
transport of cells and batteries tested and qualified under the UN 
lithium battery design qualification tests in accordance with the UN 
Manual of Tests and Criteria, Third Revised Edition. The commenter 
further stated that providing a grandfather provision for previously 
tested cells and batteries would avoid the need and expense of 
requalifying these cells and batteries in accordance with the new tests 
prescribed in the Fourth Revised Edition of the UN Manual of Tests and 
Criteria. After further consideration, we believe that authorizing an 
indefinite period for the transport of batteries that were tested in 
accordance with the UN Manual of Tests and Criteria, Third Revised 
Edition, 1999 may not be in the best interest of safety. The tests in 
the UN Manual of Tests and Criteria, Fourth Revised Edition provide a 
slightly higher level of safety and we believe that further 
consideration needs to be taken in considering whether at some point in 
time all applicable lithium batteries and cell design types should be 
proven to meet the requirements of the UN Manual of Tests and Criteria, 
Fourth Revised Edition. As a result, we will issue a proposal shortly 
specifically to address the full unrestricted adoption of the Fourth 
Revised Edition of the UN Manual of Tests and Criteria.

Section 173.186

    In Sec.  173.186, in paragraph (e), we amended the gross weight for 
UN 4G outer packages authorized for the transportation of strike-
anywhere matches, to be consistent with the UN Model Regulations by 
increasing the weight from 27 kg (60 pounds) to 30 kg (66 pounds).

Section 173.187

    We revised Sec.  173.187 to authorize certain solid hazardous 
materials to be transported in DOT specification cylinders other than 
Specification 8 and 3HT cylinders. This change eliminates the need for 
DOT Exemption ``DOT-E 11548.''

Sections 173.211, 173.212, and 173.213

    We revised these sections to authorize certain solid hazardous 
materials to be transported in DOT specification cylinders other than 
Specification 8 and 3HT cylinders. This change removed the need for DOT 
Exemption ``DOT-E 11548.''

Section 173.219

    We revised Sec.  173.219 for consistency with the UN Model 
Regulations and the ICAO Technical Instructions. Included in the 
revision is an allowance for self-inflating life-saving appliances to 
contain cartridges, power devices of Division 1.4S, for purposes of the 
self-inflating mechanism. In addition, we provided an exception from 
regulation for life-saving appliances containing only carbon dioxide 
cylinders not exceeding 100 cm\3\ capacity, provided they are 
overpacked in rigid outer packagings with a maximum gross mass of 40 
kg. Finally, the limitations currently found in Special Provision 143 
are relocated to Sec.  173.219 (see preamble discussion under Special 
Provision 143).

Section 173.220

    Paragraph (b)(2) is amended to harmonize the requirements for 
transporting flammable gas powered vehicles by air with the 
requirements of Packing Instruction 900 of the ICAO Technical 
Instructions.

Section 173.224

    Paragraph (b)(4) of this section is amended to include the new 
references for Sec.  173.225. The section reference to Sec.  173.225(e) 
for the authorization of bulk packagings is replaced with Sec.  
173.225(f) for IBCs and Sec.  173.225(h) for other bulk packagings.

Section 173.225

    This section is amended to update the Organic Peroxide Table and 
eliminate special provisions IB52 and T23 from Sec.  172.102(c). The 
purpose of the change is to consolidate the packaging requirements for 
organic peroxides into one section and to have separate tables for 
organic peroxides authorized for transport in non-bulk packagings, 
IBCs, and bulk packagings other than IBCs. The changes are as follows:
    Paragraph (a) is revised by adding paragraphs (b) and (b)(6), which 
state that bulk packagings may require a lower control temperature than 
those specified for non-bulk packagings and that an organic peroxide 
not identified in either the Organic Peroxide Table, Organic Peroxide 
IBC Table, or Organic Peroxide Portable Tank Table must be approved 
under Sec.  173.128(c).
    Paragraph (b) is revised to eliminate all IBC and other bulk 
packaging authorizations from column 6 of the Organic Peroxide Table. 
Various obsolete entries were also removed. The current paragraph (b), 
``Organic Peroxide Table,'' is moved to paragraph (c) and the current 
paragraph (c), ``New organic peroxides, formulations and samples,'' is 
moved to paragraph (b).
    The notes following the Organic Peroxide Table are changed as 
follows:
     Revise note 22 to indicate that ethylbenzene with greater 
than or equal to 25% of dilutant type A is acceptable.

[[Page 76055]]

     Revise note 23 to indicate that methyl isobutyl keytone 
with greater than or equal to 19% of dilutant type A is acceptable.
     Add a new note 29 to identify materials which are not 
included in the UN Model Regulations and note that a Competent 
Authority approval is required for international transportation.
     Remove Notes 9, 11, and 14 following the Organic Peroxide 
Table.
    In addition, The Packing Method Table found in paragraph (d), is 
revised by replacing the 200 kg maximum quantity for solids and 
combination packagings listed in OP8 with a 400 kg maximum quantity. 
Note 2, following the table, is revised to allow 200 kg of solid 
material per box and up to 400 kg of material per authorized 
combination packaging. The note also indicates that the outer packaging 
must be a box (4C1, 4C2, 4D, 4F, 4G, 4H1, and 4H2) and each inner 
packaging must be of plastics or fiber with a maximum net mass of 25 
kg. Paragraph (d)(3) is clarified by revising the text to state that 
the maximum content acceptable for glass receptacles used as inner 
packagings of a combination packaging is 0.5 kg for solids or 0.5 L for 
liquids.
    A new paragraph (e) is added to include the new ``Organic Peroxide 
IBC Table'' that replaces the current ``Table 2.--Organic Peroxide IBC 
Code (IB52)'' in Sec.  172.102(c)(4). The new table is revised to add 
an organic peroxide, ``Dicyclohexylperoxydicarbonate, not more than 42% 
as a stable dispersion, in water.'' In addition, the new Organic 
Peroxide IBC Table identifies, by technical name, those organic 
peroxides authorized for transportation in the IBCs that are 
specifically listed in the table.
    A new paragraph (f) is added to include the current IBC 
requirements contained in paragraph (e)(5) of this section. Paragraph 
(f) also includes requirements that are specific to organic peroxides 
packaged in IBCs.
    A new paragraph (g) is added to include the new ``Organic Peroxide 
Portable Tank Table,'' that replaces the current ``Portable Tank Code 
T23'' found in Sec.  172.102(c)(7)(iii). The new table is identical to 
the current table except that for UN 3109, in the entry for Pinanyl 
hydroperoxyde, 50% is replaced by 56% and all references to self-
reactive materials are removed. In addition, the Organic Peroxide 
Portable Tank Table provides certain portable tank requirements and 
identifies, by technical name, those organic peroxides authorized for 
transportation in the bulk packagings listed in the new paragraph (h).
    The current paragraph (e) is redesignated as paragraph (h). 
Paragraph (h) establishes requirements that are specific to organic 
peroxides packaged in certain bulk packagings. Additionally, the new 
``Note to Paragraph (h)(3)(vi)'' is revised to include changes brought 
forth by petition for rulemaking P-1428. The petition proposed to amend 
the current paragraph (e)(3)(vi) and allow for a second but equally 
acceptable example of an emergency-relief device sizing method to be 
added to the HMR. We agreed with the petitioner and added a statement 
to the new paragraph (h)(3)(vi) indicating that an additional example 
of an emergency-relief device sizing method can be found in the 
``American Institute of Chemical Engineers Process Safety Progress 
Journal, June 2002 issue (Vol. 21, No. 2)'' as referenced in Sec.  
171.7(b).
    The changes to this section altered the order of the paragraphs 
within this section; therefore, various citations were changed. Also, 
paragraphs referencing IB52 or TP23 are revised to indicate that those 
provisions no longer exist and the updated requirements are found in 
paragraph (e) and (g), respectively. A commenter requested that Sec.  
173.225 be revised to allow for increased industry flexibility, 
regulatory uniformity, and to better align with the UN Recommendations. 
We agree and have made the following revisions:
     Added wording to 173.225(a) to show that organic peroxides 
that are not identified in the organic peroxide table, but are in 
paragraph (b)(3) are not subject to the requirements of Sec.  173.128.
     Removed Note 1 from both entries of tert-Butyl cumyl 
peroxide and Note 11 from Dicumyl peroxide.
     Removed the sentence ``The additional requirements in 
paragraph (h)(5)(i) and (h)(5)(ii) of this section also apply'' from 
Sec.  173.225(f) and renumbered (f)(i) and (f)(ii) as (f)(1) and 
(f)(2), respectively.
     Revised the introductory text to Paragraph (h) to indicate 
that the bulk packagings that follow are for materials authorized for 
transport in a bulk packaging by Paragraph (h) and organic peroxides 
listed in the Organic Peroxide Portable Tank Table.
     Removed two occurrences of the term ``Type F'' from 
Paragraph (h)(3) to broaden the applicability of the provisions.
     Removed statement from Sec.  173.225(h)(3)(xii) indicating 
that DOT Specification 57 portable tanks are not subject to the 
requirements of paragraphs (h)(3)(ii) and (h)(3)(iv) of this section.

Sections 173.226 and 173.227

    We revised the packaging requirements of Sec. Sec.  173.226 and 
173.227 for materials poisonous by inhalation, Division 6.1, Packing 
Group I, Hazardous Zone A and Hazard Zone B. These amendments have: 
Reduced the hydrostatic test pressure of the inner drum in a drum-
within-a-drum configuration authorized in Sec.  173.226(b); 
standardized the minimum thickness requirements of the inner drums in 
the drum-within-a-drum configuration authorized in Sec. Sec.  
173.226(b) and 173.227(b); clarified the test requirements for inner 
packaging systems in Sec.  173.226(b)(2)(iv); and in Sec.  173.226(d) 
added a provision to authorize transportation of PIH materials in 
single packages when subjected to additional operational controls and 
approved by the Associate Administrator. Section 173.226(c)(2) is 
reformatted for ease of understanding. We removed an expired 
transitional date from paragraph (a) that allows the transport of 
welded cylinders filled before October 1, 2003 for the purpose of 
reprocessing or disposal of cylinders's content until December 31, 
2003. One commenter recommended that we include a provision in Sec.  
173.227(b) to allow for the testing of the outer drum of a drum-in-drum 
package as either as a package intended to contain inner packagings 
(combination package) or as a single packaging intended to contain 
solids or liquids. We agree and have revised Sec.  173.227(b) 
accordingly. Another commenter suggested that we increase the minimum 
thickness of a UN 1A1 drum in PIH service from .69 mm to 1.0 mm. 
Increasing the minimum thickness of a UN 1A1 drum in PIH service was 
not proposed in this rulemaking and inclusion of such a requirement is 
beyond the scope of this rulemaking. However, we are reviewing this 
request for consideration in a future rulemaking.

Section 173.249

    Paragraph (c) is revised to be consistent with the current 
``Bromine'' entry in the Sec.  172.101 ``Hazardous Material Table'' 
that authorizes the use of a UN portable tank conforming to tank code 
T22. A commenter suggested that we include a provision authorizing the 
returning of a tank containing bromine residue. We agree that such a 
provision is necessary and have amended Sec.  173.249 accordingly.

Sections 173.306 and 173.307

    To add clarity to the HMR, the text currently found in Sec.  
173.306(i) is removed and replaced with the text

[[Page 76056]]

currently found in Sec.  173.307(a)(5). Since Sec.  173.306 is devoted 
exclusively to limited quantities of compressed gases, relocating Sec.  
173.307(a)(5) to Sec.  173.306 makes the exception easier to find.

Section 173.313

    A new Sec.  173.313 is added to serve as the new location for the 
Portable Tank Code T50 Table. The table is renamed ``UN Portable Tank 
Table for Liquefied Compressed Gases.'' The table provides the maximum 
allowable working pressures, bottom opening requirements, pressure 
relief requirements and degree of filling requirements for liquefied 
compressed gases permitted for transport in portable tanks. The change 
relocates these packaging requirements to Part 173, which is a more 
appropriate location, and makes the special provisions less cumbersome. 
In addition, the new UN Portable Tank Table for Liquefied Compressed 
Gases is amended by revising the Column 3 heading to read ``Minimum 
design pressure (bar) * * *'' The values in column 3 are actually 
minimum values, however the title of the column is misleading because 
it uses the term ``Maximum allowable working pressure (bar) * * *''

Section 173.315

    In paragraph (a), the reference to ``portable tank provision T50 in 
Sec.  172.102'' is revised to read ``the UN Portable Tank Table for 
Liquefied Compressed Gases in Sec.  173.313.''

Section 173.323

    After further considering the proposed changes to the packaging 
authorizations for ethylene oxide in Sec.  173.323, we noted that the 
total quantity per package of ethylene oxide authorized for transport 
when glass inner receptacles are used was proposed to be increased from 
100 grams to 2.5 kg. Due to the extremely flammable and explosive 
properties of ethylene oxide and the fragile properties of glass, after 
further consideration we have chosen not to adopt the 2.5 kg outer 
package limit found in the UN Recommendations and to retain our current 
outer package limit of 100 grams. The total quantity per package when 
metal inner receptacles are used will remain unchanged from the 
proposed 2.5 kg. In this rule, paragraphs (b)(1)-(b)(3) are revised and 
consolidated for consistency with current international requirements 
for the transportation of ethylene oxide in combination packagings. 
Paragraphs (b)(1)-(b)(3) provide the current authorizations for glass, 
aluminum, and metal receptacles respectively. Amendments to this 
section include (1) removing the HMR limitation of 12 inner receptacles 
per outer package currently applied to aluminum and other metal 
receptacles, (2) removing the overpack restriction in (b)(2) which 
specifies a maximum of 10 boxes per overpack, (3) requiring a hot water 
bath test for all inner receptacles, (4) removing the pressure relief 
device and burst pressure requirements currently applied to metal 
receptacles, (5) applying the same outer package authorizations 
consistently to all inner packaging types and allowing any outer 
package authorized in Sec.  172.201(b), and (6) requiring all inner 
packagings to be suitably cushioned (the top and bottom pad and 
perimeter liner requirement currently only applied to outer packages 
containing aluminum inner packagings is removed). Though we are 
eliminating the option to utilize certain packaging authorizations for 
glass and aluminum inner packagings, we believe that this change will 
have little or no economic impact on the ethylene oxide industry 
because of the amount of materials that are transported in 
international commerce. 3M Package Engineering requested that we reduce 
the maximum quantity of ethylene oxide permitted in any metal inner 
packaging from 340 g (12 ounces) to 200 g (7 ounces). They stated that 
such a change would more adequately align the HMR with international 
standards. We agree that such a change would align the HMR with 
international requirements. However, allowing a metal inner packaging 
to contain a maximum quantity of 340 g (12 ounces) does not limit 
compliance with international requirements. In addition, we cannot 
adopt the 200 g (7 ounces) limitation in this rulemaking because such a 
change would be more restrictive then the requirements we proposed. We 
may consider adopting the 200 g (7 ounces) limitation in a future 
rulemaking.

Part 175

Section 175.10

    Consistent with an amendment to the ICAO TI, we are requiring that 
aerosol cans that are carried aboard an aircraft in accordance with 
Sec.  175.10(a)(4) have their release devices protected by a cap or 
other suitable means. In addition, the ICAO Dangerous Goods Panel will 
convene a series of working groups to develop recommendations for 
consideration during the 20th session of the Dangerous Goods Panel to 
further review this issue. These recommendations may lead to additional 
amendments to the ICAO TI. Finally, we note that non-flammable gases 
(e.g., nitrogen) other than carbon dioxide are used for the operation 
of mechanical limbs. Consistent with an amendment to the ICAO TI, we 
are proposing to provide an exception from the HMR for mechanical limbs 
that are powered by any Division 2.2 gas. One commenter recommended 
that the release device requirements added to Sec.  175.10 also be 
incorporated into Part 173. Specifically, they requested that aerosol 
cans that are transported in commerce be protected by a cap or other 
suitable means to prevent inadvertent release. They indicated that this 
change should be coordinated with the Federal Aviation Administration 
(FAA). We disagree. Section 173.24(b)(1) states that each package used 
for the shipment of hazardous materials must be constructed, 
maintained, filled, its contents so limited, and closed, so that under 
conditions normally incident to transportation there will be no 
identifiable release of hazardous materials to the environment. We feel 
this section adequately addresses the commenter's concerns, and allows 
shippers the flexibility to properly protect aerosol cans.

Section 175.85

    In Sec.  175.85, a new paragraph (j) is added to specify the cargo 
location of a package bearing the ``KEEP AWAY FROM HEAT'' handling 
marking.

Part 176

Section 176.2

    Certain definitions are revised. The definitions for ``Explosive 
article'' and ``Explosive substance'' are revised to remove an 
incorrect reference. The definition for ``Magazine'' is revised to 
include a compartment in the vessel. The definition for ``Magazine'' is 
also revised to specify vessel storage location and accessibility. The 
term ``Transport unit'' is revised to read ``Cargo transport unit'' to 
be consistent with Amendment 32 of the IMDG Code. In addition, in the 
definition ``In containers or the like'' the term ``transport unit'' is 
removed and the term ``cargo transport unit'' is added in its place.

Section 176.27

    In this section, the words ``transport unit'' are replaced with the 
words ``transport vehicle'' in each place they appear to be consistent 
with the removal of the term ``transport unit'' from the definitions in 
Sec.  176.2.

Section 176.63

    Paragraph (e) is revised to align the definition of ``Closed cargo 
transport unit'' to be consistent with the

[[Page 76057]]

definition in Amendment 32 of the IMDG Code.

Section 176.76

    Paragraph (i) is revised to clarify that for container ships, a 
distance equivalent to one container space athwartships (i.e., in the 
direction of the breadth of the vessel) away from possible sources of 
ignition applied in any direction satisfies the requirement that a 
cargo transport unit packed or loaded with flammable gas or flammable 
liquid having a flashpoint below +23 [deg]C transported on deck be 
stowed ``away from'' possible ignition sources. This is consistent with 
Amendment 32 of the IMDG Code. In addition, in paragraphs (h) and (i), 
the words ``transport unit'' are removed and replaced with the words 
``cargo transport unit'' in each place they appear to be consistent 
with Amendment 32 of the IMDG.

Section 176.83

    Paragraph (l) is revised to correct an error pertaining to the 
Segregation Table that sets forth the general requirements for 
segregation of containers on board hatchless container vessels. In 
addition, throughout the section the words ``transport units'' are 
removed and replaced with the words ``cargo transport units'' in each 
place they appear to be consistent with Amendment 32 of the IMDG. A new 
paragraph (m) is added to specify the provisions for segregation 
groups.

Section 176.84

    Paragraph (a) is revised to specify the various chemical groups 
listed in the segregation table. In the paragraph (b) Table of 
Provisions, we added eleven new provisions (codes) for certain stowage 
and segregation requirements for hazardous materials that are 
transported by vessel. In addition, in paragraph (c)(2) Provisions for 
the stowage of Class 1 (explosive) materials, we revised three notes. 
The terms ``separated from'' and ``away from'' in the codes are defined 
in Sec.  176.83 of the HMR.
    Code 133 is added to the entries ``Barium chlorate solution,'' 
UN3405; ``Barium perchlorate solution,'' UN3406; and ``Chlorate and 
magnesium chloride mixture solution,'' UN3407, that requires the 
material to be stowed ``separated from'' sulfur.
    Code 134 is added to the entry ``Aluminum alkyl halides, solid,'' 
UN3461, that requires the material to be stowed ``separated from'' 
UN2716.
    Code 135 is added to the entries ``Methylamine, aqueous solution,'' 
UN1235 and ``Trimethylamine, aqueous solutions,'' UN1297, that requires 
the material to be stowed ``separated from'' mercury and mercury 
compounds.
    Code 136 is added to the entry ``Tributylphosphane,'' UN3254, that 
requires the material to be stowed ``separated from'' carbon 
tetrachloride.
    Code 137 is added to the entries ``Arsenic compounds, liquid, 
n.o.s.,'' UN1556 and ``Arsenic compounds, solid, n.o.s.,'' UN1557, that 
requires arsenic sulphides to be stowed ``separated from'' acids.
    Code 138 is added to the entries for UN1448; UN1456; UN1479; 
UN1482; UN1490; UN1503; UN1515; UN3085; UN3087; UN3098; UN3099; UN3139; 
and UN3214, that requires the material to be stowed ``separated from'' 
peroxides.
    Code 139 is added to the entry ``1, 4-Butynediol,'' UN2716, that 
requires the material to be stowed ``separated from'' mercury salts.
    Code 140 is added to the entry ``1, 4-Butynediol,'' UN2716, that 
requires the material to be stowed ``separated from'' UN3052 and 
UN3461.
    Code 141 is added to the entries for UN1732; UN1755; UN1806; 
UN1908; UN2433; UN2859; and UN2861, that requires the material to be 
stowed ``away from'' radioactive materials.
    Code 142 is added to the entries for UN1748; UN2208; and UN2880, 
that requires packages in cargo transport units to be stowed so as to 
allow for adequate air circulation throughout the cargo.
    Code 143 is added to the entry for Organometallic Substance, 
Liquid, Pyrophoric, UN3392, prohibiting transportation on any vessel 
carrying explosives (except explosives in Division 1.4, compatibility 
group S.
    Note 19E is revised to specify that materials under entries NA0331; 
UN0004; UN0222; UN0241; and UN0402 must be stowed ``away from'' 
explosives containing chlorates or perchlorates.
    Note 22E is revised to specify that materials under the entry 
``Explosive, blasting, type C,'' must be stowed ``away from'' ammonium 
compounds and explosives containing ammonium compounds or salts.
    Note 23E is revised to specify that materials under entries UN0247; 
UN0395; UN0396; UN0397; UN0398; UN0399; UN0400; UN0449; and UN0450 must 
be ``separated from'' Division 1.4 and ``separated longitudinally by an 
intervening complete compartment or hold from'' Division 1.1, 1.2, 1.3, 
1.5, and 1.6 except from explosives of compatibility group J.
    A commenter questioned how adequate air circulation was achieved in 
a cargo transport unit. In addition, the commenter stated that it fails 
to understand why air circulation is necessary in a closed cargo 
transport unit, as indicated by Stowage Provision 142. Stowage 
Provision 142 indicates that packages in cargo transport units must be 
stowed so as to allow for adequate air circulation throughout the 
cargo. We feel cargo transport units that are properly loaded will 
allow for the adequate circulation of air by natural means so as to 
safeguard against excessive heat buildup within the cargo.

Section 176.116

    In paragraph (c), the words ``transport units'' are revised to read 
``cargo transport units.'' In addition, a new paragraph (f) is added to 
specify the under deck stowage requirements of Class 1 (explosive) 
materials allocated stowage categories 09 and 10.

Sections 176.122 and 176.124

    Sections 176.122 and 176.124 are removed and reserved.

Section 176.128

    In Sec.  176.128, the section heading and section are revised.

Section 176.132

    Section 176.132 is removed and reserved.

Section 176.133

    Section 176.133 is revised to clarify the construction and stowage 
location requirements for magazine stowage type C.

Section 176.136

    Section 176.136 is revised to clarify the special stowage 
requirements of Class 1 (explosive) materials. In addition, minor 
editorial revisions are made.

Section 176.138

    Paragraph (a) is removed and reserved to be consistent with 
Amendment 32 of the IMDG Code. This paragraph currently requires Class 
1 (explosive) material that is stowed on deck to be carried as close to 
the vessel's centerline as practicable.(See also change to Sec.  
176.170.)

Section 176.142

    Paragraph (a) is revised to remove ``Pyrophoric organometallic 
compound, water-reactive, n.o.s.'' from the list of liquid hazardous 
materials of extreme flammability that may not be transported in a 
vessel carrying Class 1 (explosive) materials. Additionally, we added 
to the above list the following new liquid entries:

[[Page 76058]]

     ``Organometallic substance, liquid, pyrophoric, UN3392''
     ``Organometallic substance, liquid, pyrophoric, water-
reactive, UN3394''
    These changes are consistent with Amendment 32 of the IMDG Code.

Section 176.144

    In this section, the words ``transport unit'' are replaced with the 
words ``cargo transport unit'' in each place they appear to be 
consistent with the definition in Amendment 32 of the IMDG Code. 
Additional notes are added to Table 176.144(a)--``Authorized Mixed 
Stowage For Explosives'' to address additional exceptions for mixed 
stowage of Class 1 materials.

Section 176.146

    In Sec.  176.146, in paragraph (d)(1), the wording ``transport 
units'' is revised to read ``cargo transport units.''

Section 176.168

    In Sec.  176.168, in the title before the section heading, the 
wording ``TRANSPORT UNITS AND SHIPBORNE BARGES'' are revised to read 
``CARGO TRANSPORT UNITS AND SHIPBORNE BARGES.''

Section 176.170

    A new paragraph (b) is added to prohibit freight containers loaded 
with Class 1 (explosive) materials, except for explosives in Division 
1.4, from being stowed in the outermost row of containers. This change 
is consistent with Amendment 32 of the IMDG Code.

Section 176.174

    Paragraphs (a) and (b) are revised to remove the references to 
portable magazines. This change is consistent with Amendment 32 of the 
IMDG Code.

Section 176.600

    In Sec.  176.600, in paragraph (a), the wording ``closed transport 
units'' is revised to read ``closed cargo transport units.''

Part 178

Section 178.274

    Paragraph (f)(v) is revised to more clearly specify the rated flow 
capacity marking required to be placed on every UN portable tank's 
pressure relief device.

Section 178.275

    Paragraph (i)(2) is revised to more clearly specify the combined 
delivery capacity of UN portable tank's pressure relief systems.

Section 178.276

    In paragraph (a)(4)(ii)(A), the reference to ``portable tank 
special provision T50'' is revised to read ``the UN Portable Tank Table 
for Liquefied Compressed Gases in Sec.  173.313.'' In addition, 
paragraph (d), the reference to ``portable tank special provision T50 
in Sec.  172.102(c)(7)'' is revised to read ``UN Portable Tank Table 
for Liquefied Compressed Gases in Sec.  173.313.'' Finally, in 
paragraph (e)(3), the reference to ``portable tank special provision 
T50 in Sec.  172.102'' is revised to read ``the UN Portable Tank Table 
for Liquefied Compressed Gases in Sec.  173.313.''

Section 178.602

    Paragraph (b) is revised to clarify the requirements applicable to 
filling packaging other than bags in preparation for testing.

Section 178.603

    Paragraph (c) is revised to add a definition indicating that a 
minimum specific gravity for solutions of water and anti-freeze is 0.95 
for testing at 18 [deg]C (0 [deg]F) or lower. Additionally, in 
paragraph (e), we specify the drop test height for liquids in single 
packagings and for inner packagings of combination packagings, when the 
test is performed in water.

Section 178.810

    Paragraph (b)(3) is revised to specify that water/anti-freeze 
solutions with a minimum specific gravity of 0.95 for testing at -18 
[deg]C (0 [deg]F) or lower are acceptable test liquids for use when 
conducting IBC drop tests. This is consistent with our amendment to 
Sec.  178.603(c)(1) regarding the testing of non-bulk packages. In 
addition, we added a sentence to clarify that when conditioning is 
required by Sec.  178.810(b), the conditioning specified in Sec.  
178.802 (which requires a higher temperature) does not apply.We 
received a comment from the Reusable Industrial Packaging Association 
(RIPA) concerning this revision. RIPA believes that RSPA intended to 
clarify that water/antifreeze solutions with a minimum specific gravity 
of 0.95 are equivalent for testing purposes to IBCs containing only 
water, thereby eliminating the need to adjust the drop height of test 
units. RIPA stated that Sec.  178.810(b)(3) should be revised to 
indicate that this solution may be considered equivalent to water for 
testing purposes. We agree and have revised the section accordingly.

Part 180

Section 180.350

    Paragraph (c) is revised to expand the definition of routine 
maintenance of IBCs to include flexible, plastic and textile IBCs.

Section 180.352

    Paragraph (d)(1)(iv) is revised to require persons other than the 
owner of metal, rigid plastics, and composite IBCs to mark the IBC 
indicating routine maintenance has been performed when such maintenance 
is performed. A new paragraph (d)(1)(v) is added to this section. This 
paragraph states that retests and inspections performed under 
paragraphs (d)(1)(i) and (ii) of this section may be used to satisfy 
the tests and inspections required by paragraph (b) of this section. 
This addition incorporates changes made to the 12th revised edition of 
the Transport of Dangerous Goods Model Regulations into the HMR. Three 
commenters requested that we revise Sec.  180.352 to distinguish 
requirements applicable to repair and routine maintenance of IBCs. We 
agree and have revised Sec.  180.352 creating a new paragraph entitled, 
``Requirements applicable to routine maintenance of IBCs.''

V. Regulatory Analyses and Notices

A. Statutory/Legal Authority for This Rulemaking

    This final rule is published under the following statutory 
authorities:
    1. 49 U.S.C. 5103(b) authorizes the Secretary of Transportation to 
prescribe regulations for the safe transportation, including security, 
of hazardous material in intrastate, interstate, and foreign commerce. 
This final rule amends regulations to maintain alignment with 
international standards by incorporating various amendments, including 
changes to proper shipping names, hazard classes, packing groups, 
special provisions, packaging authorizations, air transport quantity 
limitations and vessel stowage requirements. To this end, as discussed 
in detail earlier in this preamble, the final rule amends the HMR to 
more fully align it with the biennial updates of the UN 
Recommendations, the IMDG Code and the ICAO Technical Instructions to 
facilitate the transport of hazardous materials in international 
commerce.
    2. 49 U.S.C. 5120(b) authorizes the Secretary of Transportation to 
ensure that, to the extent practicable, regulations governing the 
transportation of hazardous materials in commerce are consistent with 
standards adopted by international authorities. This final rule amends 
the HMR to maintain alignment with international standards by 
incorporating various amendments to facilitate the transport of 
hazardous material in international commerce. To this end, as discussed 
in detail earlier in this preamble, the final rule incorporates changes 
into the HMR

[[Page 76059]]

based on the Thirteenth Revised Edition of the UN Recommendation, 
Amendment 32 to the IMDG Code, and the 2005-2006 ICAO Technical 
Instructions, which become effective January 1, 2005. The continually 
increasing amount of hazardous materials transported in international 
commerce warrants the harmonization of domestic and international 
requirements to the greatest extent possible. Harmonization serves to 
facilitate international transportation; at the same time, 
harmonization ensures the safety of people, property, and the 
environment by reducing the potential for confusion and 
misunderstanding that could result if shippers and transporters were 
required to comply with two or more conflicting sets of regulatory 
requirements. While the intent of this rulemaking is to align the HMR 
with international standards, we review and consider each amendment on 
its own merit based on its overall impact on transportation safety and 
the economic implications associated with its adoption into the HMR. 
Our goal is to harmonize without sacrificing the current HMR level of 
safety and without imposing undue burdens on the regulated public. 
Thus, as discussed in detail earlier in this preamble, there are 
several instances where we elected not to adopt a specific provision of 
the UN Recommendations, the IMDG Code or the ICAO Technical 
Instructions; further, we are maintaining a number of current 
exceptions for domestic transportation that should minimize the 
compliance burden on the regulated community.

B. Executive Order 12866 and DOT Regulatory Policies and Procedures

    This 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. This final rule is not 
considered a significant rule under the Regulatory Policies and 
Procedures of the Department of Transportation [44 FR 11034]. Benefits 
resulting from the adoption of the amendments in this final rule 
include enhanced transportation safety resulting from the consistency 
of domestic and international hazard communications and continued 
access to foreign markets by domestic shippers of hazardous materials. 
This final rule applies to offerors and carriers of hazardous 
materials, such as chemical manufacturers, chemical users and 
suppliers, packaging manufacturers, distributors, battery 
manufacturers, radiopharmaceutical companies, and training companies.
    The majority of amendments in this final rule should result in cost 
savings and ease the regulatory compliance burden for shippers engaged 
in domestic and international commerce, including trans-border 
shipments within North America. For example, cost savings will be 
realized by shippers and carriers as a result of the following:

--Eliminating the air eligibility marking requirement.
--Amendments allowing numerous Class 3, PG II materials with a Class 8 
sub-risk and others to be transported as a limited quantity.
--Allowing cylinders to be used for many more substances than currently 
authorized.
--Allowing salvage packagings to be used for non-conforming packages; 
and generally minimizing differences between U.S. and international 
hazardous materials transportation regulations.

    We are authorizing a delayed effective date and a one-year 
transition period to allow for training of employees and to ease any 
burden on entities affected by the amendments. The total net increase 
in costs to businesses in implementing this rulemaking is considered to 
be minimal and a regulatory evaluation is available for review in the 
Docket.

C. Executive Order 13132

    This final rule has been analyzed in accordance with the principles 
and criteria contained in Executive Order 13132 (``Federalism''). This 
final rule preempts State, local and Indian tribe requirements but does 
not propose any regulation that has substantial direct effects on the 
States, the relationship between the national government and the 
States, or the distribution of power and responsibilities among the 
various levels of government. Therefore, the consultation and funding 
requirements of Executive Order 13132 do not apply.
    The Federal hazardous material transportation law, 49 U.S.C. 5101-
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 materials;
    (2) The packing, repacking, handling, labeling, marking, and 
placarding of hazardous materials;
    (3) The preparation, execution, and use of shipping documents 
related to hazardous materials 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; and
    (5) The design, manufacture, fabrication, marking, maintenance, 
recondition, repair, 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 subject items (1), (2), (3), and 
(5) above and preempts State, local, and Indian tribe requirements not 
meeting the ``substantively the same'' standard. This final rule is 
necessary to incorporate changes adopted in international standards, 
effective January 1, 2005. If the changes in this final rule are not 
adopted in the HMR, U.S. companies, including numerous small entities 
competing in foreign markets, are at an economic disadvantage. These 
companies are forced to comply with a dual system of regulations. The 
changes in this rulemaking are intended to avoid this result. Federal 
hazardous materials transportation law provides at section 5125(b)(2) 
that, if DOT issues a regulation concerning any of the covered 
subjects, DOT must determine and publish in the Federal Register the 
effective date of Federal preemption. The effective date may not be 
earlier than the 90th day following the date of issuance of the final 
rule and not later than two years after the date of issuance. The 
effective date of Federal preemption is March 21, 2005.

D. Executive Order 13175

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

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

    The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires an 
agency to review regulations to assess their impact on small entities, 
unless the agency determines that a rule is not expected to have a 
significant impact on a substantial number of small entities. This 
final rule facilitates the transportation of hazardous materials in 
international commerce by providing consistency with international 
standards. This final rule applies to offerors and carriers of 
hazardous materials, some of whom are small entities, such as chemical 
users and suppliers, packaging manufacturers, distributors, battery 
manufacturers, and

[[Page 76060]]

training companies. As discussed above, under Executive Order 12866, 
the majority of amendments in this final rule should result in cost 
savings and ease the regulatory compliance burden for shippers engaged 
in domestic and international commerce, including trans-border 
shipments within North America.
    Many companies will realize economic benefits as a result of these 
amendments. Additionally, the changes brought forth by this final rule 
will relive U.S. companies, including small entities competing in 
foreign markets, from the burden of complying with a dual system of 
regulations. Therefore, I certify that these amendments will not, if 
promulgated, have a significant economic impact on a substantial number 
of small entities.
    This final rule has been developed in accordance with Executive 
Order 13272 (``Proper Consideration of Small Entities in Agency 
Rulemaking'') and DOT's procedures and policies to promote compliance 
with the Regulatory Flexibility Act to ensure that potential impacts of 
draft rules on small entities are properly considered.

F. Paperwork Reduction Act

    Under the Paperwork Reduction Act of 1995, no person is required to 
respond to a collection of information unless it displays a valid 
Office of Management and Budget (OMB) control number. Section 
1320.8(d), Title 5, Code of Federal Regulations requires that RSPA 
provide interested members of the public and affected agencies an 
opportunity to comment on information collection and recordkeeping 
requests. RSPA currently has two approved information collections 
affecting this final rule: OMB Control Number 2137-0557, ``Approvals 
for Hazardous Materials'' with 25,605 burden hours and $562,837.40 
burden costs; and OMB Control Number 2137-0613, ``Subsidiary Hazard 
Class & Number/Type of Packagings'' with 63,309 burden hours and 
$216,705 burden costs.
    There are minor editorial changes under this rule. However, there 
is no net increase in burden for OMB Control Number 2137-0557 or OMB 
Control Number 2137-0613. We estimate that the total information 
collection and recordkeeping burden as follows:
    ``Approvals for Hazardous Materials''

G. Regulatory Identifier Number (RIN)

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

H. Unfunded Mandates Reform Act

    This final rule does not impose unfunded mandates under the 
Unfunded Mandates Reform Act of 1995. It does not result in costs of 
$120.7 million or more to either State, local or tribal governments, in 
the aggregate, or to the private sector, and is the least burdensome 
alternative that achieves the objective of the rule.

I. Environmental Assessment

    The National Environmental Policy Act of 1969 (NEPA) requires 
Federal agencies to consider the consequences of major Federal actions 
and prepare a detailed statement on actions significantly affecting the 
quality of the human environment. We developed an assessment to 
determine the effects of these revisions on the environment and whether 
a more comprehensive environmental impact statement may be required. 
Our findings conclude that there are no significant environmental 
impacts associated with this final rule. Consistency in the regulations 
for the transportation of hazardous materials aids in the shipper's 
understanding of what is required and permits shippers to more easily 
comply with safety regulations and avoid the potential for 
environmental damage or contamination. For interested parties, an 
environmental assessment is available in the public docket.

J. Privacy Act

    Anyone is able to search the electronic form of any written 
communications and comments received into any of our dockets by the 
name of the individual submitting the document (or signing the 
document, if submitted on behalf of an association, business, labor 
union, etc.). You may review DOT's complete Privacy Act Statement in 
the Federal Register published on April 11, 2000 (Volume 65, Number 70;
