I. Background 

On December 21, 1990, the Research 

and Special Programs Administration 

(RSPA), the predecessor agency to the 

Pipeline and Hazardous Materials Safety 

Administration (PHMSA, we) published 

a final rule (Docket HM–181; 55 FR 

52402) based on the UN 

Recommendations on the Transport of 

Dangerous Goods, to comprehensively 

revise the Hazardous Materials 

Regulations (HMR), 49 CFR parts 171 to 

180, for harmonization with the 

international standards. Since 

publication of the 1990 final rule, we 

have issued six additional international 

harmonization final rules, (Dockets 

HM–215A, 59 FR 67390; HM–215B, 62 

FR 24690; HM–215C, 64 FR 10742; HM– 

215D, 66 FR 33316; HM–215E, 68 FR 

44992; and HM–215G, 69 FR 76044). 

The rules provided additional 

harmonization with international 

transportation requirements by more 

fully aligning the HMR with the 

corresponding biennial updates of the 

UN Recommendations, the IMDG Code 

and the ICAO Technical Instructions. 

The UN Recommendations are not 

regulations, but rather are 

recommendations issued by the UN 

Committee of Experts on the Transport 

of Dangerous Goods (TDG) and on the 

Globally Harmonized System of 

Classification and Labelling of 

Chemicals (GHS). These 

recommendations are amended and 

updated biennially by the UN 

Committee of Experts. They serve as the 

basis for national, regional, and 

international modal regulations, 

including the International Maritime 

Organization’s International Maritime 

Dangerous Goods Code (IMDG Code), 

and the International Civil Aviation 

Organization’s Technical Instructions 

for the Transport of Dangerous Goods by 

Air (ICAO Technical Instructions). 

The harmonization of domestic and 

international standards becomes 

increasingly important as the volume of 

hazardous materials transported in 

international commerce grows. 

Harmonization serves to facilitate 

international transportation, while 

maintaining appropriate protection of 

people, property, and the environment. 

Although the intent of the 

harmonization rulemakings is to align 

the HMR with international standards, 

we review and consider each 

amendment on its own merit. Each 

amendment is considered on the basis 

of its overall impact on transportation 

safety and the economic implications 

associated with its adoption into the 

HMR. Our goal is to harmonize without 

diminishing the level of safety currently 

provided by the HMR and without 

imposing undue burdens on the 

regulated public. In our efforts to 

continue aligning the HMR with 

international requirements, in this 

NPRM, we are proposing to incorporate 

changes into the HMR based on the 

Fourteenth revised edition of the UN 

Recommendations, Amendment 33 to 

the IMDG Code, and the 2007–2008 

ICAO Technical Instructions which 

become effective January 1, 2007. We 

are also addressing petitions for 

rulemaking concerning harmonization 

with international standards and 

additional measures to facilitate 

international transportation.

II. Sunset Provision 

To assure the HMR account for new 

technologies and updated business 

practices, PHMSA is considering 

whether certain requirements proposed 

in this NPRM should be afforded a 

‘‘sunset’’ provision. If we adopt such a 

provision, certain amendments adopted 

through this rulemaking would expire 

after a fixed amount of time (e.g., 10 

years) from the publication date of the 

final rule. 

Harmonizing the HMR with 

international transportation 

requirements facilitates the 

transportation of hazardous materials in 

international commerce by eliminating 

the need for shippers and carriers to 

comply with two different sets of 

regulations. Certain standards that we 

are proposing to adopt by reference 

likely will be updated periodically in 

response to changes in international 

standards or may be replaced by other 

more relevant or technically superior 

standards. Future changes to these 

standards would have to consider 

whether to retain or extend the sunset 

date. If we choose to do nothing, a 

sunset provision would mean the HMR 

would revert to the language and 

requirements in effect before the 

issuance of the final rule. We are 

requesting comments on whether 

certain amendments should be tied to a 

sunset provision. 

III. Overview of Proposed Changes in 

This NPRM 

In this NPRM, we are proposing the 

following amendments to the HMR: 

• Adoption of a single shipping paper 

description sequence (identification 

number, proper shipping name, hazard 

class or division, packing group). 

Currently, the HMR permit the shipping 

paper description sequence to start with 

either the identification number or the 

proper shipping name. 

• Requirement to indicate the net 

quantity of hazardous material per 

package on the shipping paper if 

transportation is by aircraft. The HMR 

do not currently require this 

information on a shipping paper. 

• Incorporation by reference of the 

updated ICAO Technical Instructions, 

IMDG Code, and UN Recommendations. 

• Amendments to the Hazardous 

Materials Table (HMT) to add, revise, or 

remove certain proper shipping names, 

hazard classes, packing groups, special 

provisions, packaging authorizations, 

bulk packaging requirements, passenger 

and cargo aircraft maximum quantity 

limitations and vessels stowage 

provisions. 

• Revision of the ORGANIC 

PEROXIDE label and placard. 

• Revision of the classification 

criteria for PG III flammable liquids. 

• Revision of the classification 

criteria and packing group assignment 

for Division 6.1 materials. 

• Requirements for the transportation 

of fuel cells containing flammable 

liquid. 

• Adoption of a one-packet limit for 

matches carried by airline passengers or 

crew members. 

IV. Overview of International 

Standards Not Being Considered for 

Adoption in This NPRM 

This NPRM proposes changes to the 

HMR based on amendments to the 

Fourteenth revised edition of the UN 

Recommendations, Amendment 33 to 

the IMDG Code, and the 2007–2008 

ICAO Technical Instructions, which 

become effective January 1, 2007. 

However, we are not proposing to adopt 

all of the amendments to those 

documents into the HMR. In many 

cases, amendments to the international 

regulations have not been adopted 

because the framework or structure of 

the HMR makes adoption unnecessary. 

In other cases, we have handled, or will 

be handling, the amendments in 

separate rulemaking proceedings. For 

example, we addressed requirements 

related to the transportation of 

infectious substances in a final rule 

published June 2, 2006, under Docket 

HM–226A (71 FR 32244). Similarly, we 

adopted amendments relating to the use 

of UN cylinders and pressure vessels in 

a final rule published June 12, 2006, 

under Docket HM–220E (71 FR 33858). 

If we have inadvertently omitted an 

amendment in this NPRM, we will 

attempt to include the omission in the 

final rule. However, our ability to make 

changes in a final rule is limited by 

requirements of the Administrative 

Procedure Act. In some instances, we 

can adopt a provision inadvertently 

omitted in the NPRM if it is clearly 

within the scope of changes proposed in 

the notice, does not require substantive 

changes from the international standard 

on which it is based, and imposes 

minimal or no cost impacts on persons 

subject to the requirement. Otherwise, 

in order to provide opportunity for 

notice and comment, the change must 

be proposed in an NPRM. 

One of the goals of this rulemaking is 

to continue to maintain consistency 

between the HMR and the international 

requirements. We are not striving to 

make the HMR identical to the 

international regulations but rather to 

remove or avoid potential barriers to 

international transportation. 

Below is a listing of those significant 

amendments to the international 

regulations that we are not proposing to 

adopt in this NPRM with a brief 

explanation of why the amendment was 

not included: 

• Environmentally hazardous 

substances. The UN Recommendations 

have not yet been adopted by ICAO and 

IMO. These changes will be considered 

in a separate rulemaking proceeding. 

• Hazardous materials security. Like 

the HMR, the UN Recommendations 

require carriers, consignors and others 

engaged in the transport of ‘‘high 

consequence’’ dangerous goods to 

adopt, implement and comply with a 

security plan that addresses the 

transportation risks associated with 

these materials. A major difference 

between the HMR and the UN 

Recommendations is the quantity of 

hazardous material that triggers the 

requirement for a security plan. We are 

analyzing the differences and, based on 

our conclusions, will consider a 

separate rulemaking to address this 

issue. 

• Requirements for radioactive 

materials. We are not proposing to 

adopt provisions pertaining to the 

transportation of Class 7 (radioactive) 

materials. Amendments to requirements 

pertaining to the transportation of Class 

7 materials are based on changes 

contained in the International Atomic 

Energy Agency (IAEA) publication, 

‘‘IAEA Safety Standards Series: 

Regulations for the Safe Transport of 

Radioactive Materials.’’ Due to their 

complexity, these changes will be 

addressed in a separate rulemaking. 

• Default classification system for 

fireworks. We are not proposing to adopt 

these provisions of the UN 

Recommendations because we do not 

believe the UN classification system 

provides an equivalent level of safety to 

the current HMR requirements. Under 

the HMR, fireworks must be classed and 

approved by the Associate 

Administrator for Hazardous Materials 

Safety; the approvals are based on 

American Pyrotechnic Association 

Standard 87–1. 

• Fuel cells. We are not proposing to 

adopt provisions for the carriage of fuel 

cell cartridges in the passenger cabin of 

a passenger aircraft that were adopted 

by ICAO. Also, we are not proposing to 

adopt the packaging provisions for the 

transport of ‘‘Hydrogen in a metal 

hydride storage system,’’ (UN3468), as 

adopted by ICAO. Currently, the HMR 

allow transportation of these storage 

systems by motor vehicle and rail under 

the terms of an exemption and by motor 

vehicle, rail, cargo vessel and cargo 

aircraft with approval of the Associate 

Administrator. These issues will be

51896 Federal Register / Vol. 71, No. 169 / Thursday, August 31, 2006 / Proposed Rules 

considered in a separate rulemaking 

proceeding. 

• Marking of Limited Quantity 

shipments. The ICAO Technical 

Instructions adopted a marking 

requirement for packages containing a 

limited quantity of hazardous material 

that consists of the identification 

number of the material placed within a 

square-on-point border. The marking is 

anticipated to become effective January 

1, 2009. Except for transportation by 

aircraft, this marking is currently 

authorized under the HMR as an 

alternative to marking the proper 

shipping name on the package; we are 

allowing continued use of this marking 

to minimize transportation costs and 

provide flexibility. 

V. Section-by-Section Review 

Part 171 

Section 171.7 

Section 171.7 lists the standards 

incorporated by reference into the HMR. 

We propose to update the incorporation 

by reference materials for the ICAO 

Technical Instructions, the IMDG Code, 

the UN Recommendations and the UN 

Manual of Tests and Criteria. The 

updated editions of these standards 

become effective January 1, 2007. 

The standards would be updated as 

follows: 

• The ICAO Technical Instructions, 

2007–2008 Edition. 

• The IMDG Code, Amendment 33. 

• The UN Recommendations, 

Fourteenth revised edition. 

• The UN Manual of Tests and 

Criteria, Fourth revised edition (2003), 

and Addendum 2, (2004). 

Section 171.14 

This section lists specific transition 

periods for certain provisions adopted 

into the HMR. Paragraph (b) lists 

transitional provisions related to revised 

placarding requirements. In this NPRM, 

we propose to remove paragraph (b) 

because the transitional period has 

expired. 

Paragraph (d) of this section specifies 

transition provisions for previously 

adopted amendments intended to 

harmonize the HMR with international 

standards. We are proposing revisions to 

this paragraph to provide specific 

transitional provisions for certain of the 

amendments proposed in this NPRM. 

We are proposing an effective date of 

January 1, 2007, and a mandatory 

compliance date of January 1, 2008. We 

propose to permit voluntary compliance 

as of January 1, 2007, to correspond 

with the effective implementation dates 

of the 2007–2008 ICAO Technical 

Instructions and Amendment 33 of the 

IMDG Code. This authorization would 

allow shippers to prepare their 

international shipments in accordance 

with international standards that will 

become effective on January 1, 2007. 

Paragraph (e) of this section contains 

an outdated transition provision. In this 

NPRM, we propose to replace the 

outdated transition provision with a 

new paragraph (e) that would permit 

use for domestic shipments of the 

shipping description sequences in effect 

on December 31, 2006, until January 1, 

2009. See the § 172.202 preamble 

discussion for a complete explanation of 

the shipping description sequence issue. 

Paragraph (f) of this section contains 

an outdated transitional provision. We 

propose to revise paragraph (f) by 

removing the current provision and 

adding a transitional provision to allow 

continued display of Division 5.2 labels 

and placards conforming to the 

specifications in effect on December 31, 

2006, until January 1, 2011. See the 

§§ 172.407 and 172.427 preamble 

discussions for a complete explanation 

of this issue. 

In new paragraph (g), we are 

proposing to allow continued use of the 

Class 3 and Division 6.1 classification 

criteria and packing group assignments 

in effect on December 31, 2006, until 

January 1, 2012. See §§ 173.120 and 

174.133 preamble discussions for a 

complete explanation of this issue. 

Part 172 

Section 172.101 

Section 172.101 contains the 

Hazardous Materials Table (HMT) and 

explanations for each of the columns in 

the HMT. Paragraph (d) of this section 

addresses column 3 of the HMT, which 

contains the hazard class or division for 

each specific material listed in the 

HMT. Paragraph (d)(4) addresses entries 

classed as combustible liquids. We are 

proposing to revise paragraph (d)(4) to 

revise the lower limit for classing a 

material as a combustible liquid from 

60.5 °C (141 °F) to 60 °C (140 °F). This 

is consistent with recent changes to the 

classification of flammable liquids 

based on the GHS and adoption into the 

UN Recommendations. 

The § 172.101 Hazardous Materials 

Table (HMT): In the § 172.101 

Hazardous Materials Table (HMT), we 

are proposing to make various 

amendments. Readers should review all 

changes for a complete understanding of 

the proposed Table amendments. For 

purposes of the Government Printing 

Office’s typesetting procedures, 

proposed changes to the HMT will 

appear under three sections of the 

Table, ‘‘remove,’’ ‘‘add’’ and ‘‘revise.’’

Certain entries in the HMT, such as 

those with proposed revisions to the 

proper shipping names, will appear as 

a ‘‘remove’’ and ‘‘add.’’ Under this 

NPRM, the proposed amendments to the 

HMT for the purpose of harmonizing 

with international standards, unless 

otherwise stated, include, but are not 

limited to the following: 

1. We propose to correct Column (7) 

Special provisions of the HMT by 

removing Special provision 101 which 

requires the name of the particular 

substance or article to be specified. With 

the introduction of the letter ‘‘G’’ for 

these materials in Column (1), requiring 

the n.o.s. and generic proper shipping 

names to be supplemented with the 

technical name of the hazardous 

material, Special provision 101 becomes 

obsolete and duplicative. The affected 

entries are as follows: 

UN0349 .............................................................................. Articles, explosive, n.o.s. 

UN0350 .............................................................................. Articles, explosive, n.o.s.

2. Amendment 32 of the IMDG Code 

added a new segregation group for 

alkalis. For consistency with 

international regulations and in 

response to a petition from Horizon 

Lines (P–1470), we are proposing to 

revise the Vessel Stowage Provisions in 

Column (10B) by adding Segregation 

Code ‘‘52’’ (Stow ‘‘Separated from’’

acids) to certain entries. The affected 

entries are as follows: 

UN2733 .............................................................................. Amines, flammable, corrosive, n.o.s. or Polyamines, flammable, corrosive, n.o.s.

TP33. Special provision T3 specifies the 

applicable minimum test pressure, the 

minimum shell thickness, bottom 

opening requirements and pressure 

relief requirements when transporting 

this material in a UN portable tank. 

Special provision TP33 specifies 

requirements applicable to the 

transportation of this material in IM and 

UN Specification portable tanks. 

5. The entry, ‘‘Articles, explosive, 

extremely insensitive or Articles, EEI, ’’

UN0486, would be revised by removing 

Special provision 101 which requires 

the name of the particular substance or 

article to be specified. 

6. The entry ‘‘Benzyl bromide,’’

UN1737, PG II, would be revised by 

removing the reference to § 173.153 

‘‘Exceptions for Division 6.1 (poisonous 

materials)’’ in Column (8A). 

7. The entry ‘‘Benzyl chloride,’’

UN1738, PG II, would be revised by 

removing the reference to § 173.153 

‘‘Exceptions for Division 6.1 (poisonous 

materials)’’ in Column (8A). 

8. In accordance with changes in the 

Fourteenth revised edition of the UN 

Recommendations, we propose to 

remove the following entries: 

—The entry ‘‘Carbon dioxide and 

nitrous oxide mixtures,’’ UN1015; 

—The entry ‘‘Carbon dioxide and 

oxygen mixtures, compressed,’’

UN1014; and 

—The entry ‘‘Carbon monoxide and 

hydrogen mixture, compressed,’’

UN2600. 

9. The entry, ‘‘Charges, shaped, 

flexible, linear,’’ UN0288, would be 

revised by removing Special provision 

101, which requires the name of the 

particular substance or article to be 

specified. 

10. The entry ‘‘Chlorosilanes, 

corrosive, n.o.s.,’’ UN2987, PG II, would 

be revised by removing the reference to 

§ 173.154 ‘‘Exceptions for Class 8 

(corrosive materials)’’ in Column (8A). 

11. The entry ‘‘Chlorosilanes, 

flammable, corrosive, n.o.s.,’’ UN2985, 

PG II, would be revised by removing the 

reference to § 173.150 ‘‘Exceptions for 

Class 3 (flammable) and combustible 

liquids’’ in Column (8A). 

12. The entry ‘‘Chlorosilanes, toxic, 

corrosive, n.o.s.,’’ UN3361, PG II, would 

be revised by removing the reference to 

§ 173.153 ‘‘Exceptions for Division 6.1 

(poisonous materials)’’ in Column (8A). 

13. The entry ‘‘Chlorosilanes, toxic, 

corrosive, flammable, n.o.s.,’’ UN3362, 

PG II, would be revised by removing the 

reference to § 173.153 ‘‘Exceptions for 

Division 6.1 (poisonous materials)’’ in 

Column (8A). 

14. The entry ‘‘Chromium trioxide, 

anhydrous,’’ UN1463, Column (6) 

would be revised by adding the Division 

6.1 subsidiary hazard labeling 

requirement. 

15. The entry ‘‘Compressed gas, 

n.o.s.,’’ UN1956, would be revised by 

adding Special provision 77. Special 

provision 77 requires, for domestic 

transportation, a Division 5.1 subsidiary 

risk label when a carbon dioxide and 

oxygen mixture contains more than 

23.5% oxygen. 

16. The entry, ‘‘Contrivances, wateractivated, with burster, expelling charge 

or propelling charge,’’ UN0248, would 

be revised by removing Special 

provision 101, which requires the name 

of the particular substance or article to 

be specified. In addition, the letter ‘‘G’’

would be added to Column (1), 

requiring the proper shipping name to 

be supplemented with the technical 

name of the hazardous material. 

17. The entry, ‘‘Contrivances, wateractivated, with burster, expelling charge 

or propelling charge,’’ UN0249, would 

be revised by removing Special 

provision 101, which requires the name 

of the particular substance or article to 

be specified. In addition, the letter ‘‘G’’

would be added to Column (1), 

requiring the proper shipping name to 

be supplemented with the technical 

name of the hazardous material. 

18. The entry ‘‘Corrosive liquid, 

acidic, inorganic, n.o.s.,’’ UN3264, PG II, 

would be revised by removing Special 

provision A6. Special provision A6 

specifies that for combination 

packagings, if plastic inner packagings 

are used, they must be packed in tightly 

closed metal receptacles before packing 

in outer packagings. Special provision 

A6 applies only to the PG I entry of this 

material. 

19. The proper shipping name for the 

entry ‘‘Crotonaldehyde, Stabilized,’’

UN1143, would be revised to read 

‘‘Crotonaldehyde or Crotonaldehyde, 

stabilized’’ and to add proposed new 

Special provision 175. New Special 

provision 175 specifies this material is 

required to be stabilized when in 

concentrations of not more than 99%. 

The revision appears as a ‘‘Remove/ 

Add’’ in this rulemaking. 

20. The proper shipping name for the 

entry ‘‘Crotonic acid, liquid,’’ UN2823, 

would be corrected to read ‘‘Crotonic 

acid, liquid’’ and the Identification 

Number would be revised to read 

‘‘UN3472.’’ This revision appears as a 

‘‘Remove/Add’’ in this rulemaking. 

21. The proper shipping name for the 

entry ‘‘Crotonic acid, solid,’’ UN2823, 

would be corrected to read ‘‘Crotonic 

acid, solid,’’ UN2823. This correction 

appears as a ‘‘Remove/Add’’ in this 

rulemaking. 

22. In accordance with the ICAO 

Technical Instructions, the entry 

‘‘Dangerous Goods in Machinery or 

Dangerous Goods in Apparatus,’’ UN 

3363, would be revised by adding 

quantity limits for transportation by 

aircraft. The quantity limits will be 

specified in a new Special provision 

A105. 

23. The entry ‘‘Ethyltrichlorosilane,’’

UN1196, PG II, would be revised by 

removing the reference to § 173.150 

‘‘Exceptions for Class 3 (flammable) and 

combustible liquids’’ in Column (8A). 

24. The entry ‘‘Formic acid,’’ UN1779, 

would be revised to read ‘‘Formic acid 

with more than 85% acid by mass’’ and 

the Class 3 subsidiary hazard would be 

added in Column (6). This revision 

appears as a ‘‘Remove/Add’’ in this 

rulemaking. 

25. A new entry, ‘‘Formic acid with 

not less than 10% but not more than 

85% acid by mass,’’ UN3412, would be 

added. 

26. A new entry, ‘‘Formic acid with 

not less than 5% but less than 10% acid 

by mass,’’ UN3412, would be added. 

27. A new entry, ‘‘Fuel cell cartridges 

containing flammable liquids,’’

UN3473, would be added. 

28. The entry ‘‘Hydrazine aqueous 

solutions, with more than 37% 

hydrazine, by mass’’ UN2030, PG I, 

would be revised by removing Special 

provision 151. Special provision 151 

specifies that if this material meets the 

definition of a flammable liquid in 

§ 173.120 of the HMR, a FLAMMABLE 

LIQUID label is required and the basic 

description on the shipping paper must 

indicate the Class 3 subsidiary hazard. 

Changes to the Fourteenth revised 

edition of the UN Recommendations 

removed this requirement. Shipping 

paper and labeling requirements for 

materials with subsidiary hazards are 

addressed in §§ 172.202 and 172.402, 

respectively. 28a. The entry ‘‘Hydrogen 

in a metal hydride storage system,’’


erjones on PROD1PC72 with PROPOSALS2
Federal Register / Vol. 71, No. 169 / Thursday, August 31, 2006 / Proposed Rules 51899 

UN3468, would be revised by amending 

Column (9B) to authorize 100 kg gross. 

29. The entry ‘‘Hydrogen peroxide 

and peroxyacetic acid mixtures, 

stabilized with acids, water, and not 

more than 5 percent peroxyacetic acid,’’

UN3149, would be revised by adding 

Special provision IP5. When this 

material is transported in an IBC, 

Special provision IP5 specifies the IBC 

must have a device to allow venting. 

30. The entry ‘‘Hydrogen peroxide, 

aqueous solutions with more than 40 

percent but not more than 60 percent 

hydrogen peroxide (stabilized as 

necessary),’’ UN2014, would be revised 

by adding Special provision IP5. When 

this material is transported in an IBC, 

Special provision IP5 specifies the IBC 

must have a device to allow venting. 

31. The entry ‘‘Hydrogen peroxide, 

aqueous solutions with not less than 20 

percent but not more than 40 percent 

hydrogen peroxide (stabilized as 

necessary),’’ UN2014, would be revised 

by adding Special provision IP5. When 

this material is transported in an IBC, 

Special provision IP5 specifies the IBC 

must have a device to allow venting. 

32. The entry ‘‘Hydrogen peroxide, 

aqueous solutions with not less than 8 

percent but less than 20 percent 

hydrogen peroxide (stabilized as 

necessary),’’ UN2984, would be revised 

by adding Special provision IP5. When 

this material is transported in an IBC, 

Special provision IP5 specifies the IBC 

must have a device to allow venting. 

33. The entry ‘‘Hydrogen peroxide, 

stabilized or Hydrogen peroxide 

aqueous solutions, stabilized with more 

than 60 percent hydrogen peroxide,’’

UN2015, would be revised by removing 

Special provision T10 and adding 

Special provision T9. When this 

material is transported in a UN portable 

tank, Special provision T10 requires the 

UN portable tank pressure relief device 

to comply with the requirements 

specified in § 178.275(g)(3) of the HMR. 

The proposed addition of Special 

provision T9 would remove this 

requirement. 

34. For the entry 

‘‘Hydrogendifluorides, n.o.s.,’’ UN1740, 

PG II and III, the proper shipping name 

would be revised by to read 

‘‘Hydrogendifluorides, solid, n.o.s.’’

This revision appears as a ‘‘Remove/ 

Add’’ in this rulemaking. 

35. A new entry 

‘‘Hydrogendifluorides, solution, n.o.s.,’’

UN3471, PG II and III, would be added. 

36. The entry ‘‘Hydroquinone, solid,’’

UN2662, would be removed. 

37. The entry ‘‘Hydroquinone 

solution,’’ UN3435, would be removed. 

38. The entry ‘‘Hypochlorite 

solutions,’’ UN1791, PG II, would be 

revised by adding Special provision IP5. 

When this material is transported in an 

IBC, Special provision IP5 specifies the 

IBC must have a device to allow 

venting. 

39. For the entry ‘‘Lead phosphite, 

dibasic,’’ UN2989, PG II, the quantity 

limitations in Columns (9A) and (9B) 

would be revised to read 15 kg and 50 

kg, respectively. 

40. For the entry ‘‘Lead phosphite, 

dibasic,’’ UN2989, PG III, the quantity 

limitations in Columns (9A) and (9B) 

would be revised to read 25 kg and 100 

kg, respectively. 

41. The entry 

‘‘Methylphenyldichlorosilane,’’

UN2437, PG II, would be revised by 

removing the reference to § 173.154 

‘‘Exceptions for Class 8 (corrosive 

materials)’’ in Column (8A). 

42. The entry ‘‘Motor fuel anti-knock 

mixtures,’’ UN1649, would be corrected 

by removing the subsidiary hazard label 

requirement in Column (6). 

43. The entry ‘‘Organometallic 

substance, solid, pyrophoric,’’ UN3391, 

PG I, would be revised by correcting the 

Column (8B) Non-bulk packaging entry 

‘‘181’’ to read ‘‘187.’’

44. The entry ‘‘Organometallic 

substance, solid, pyrophoric, waterreactive,’’ UN3393, PG I, would be 

revised by correcting the Column (8B) 

Non-bulk packaging entry ‘‘181’’ to read 

‘‘187.’’

45. A new entry, ‘‘Paint, corrosive, 

flammable (including paint, lacquer, 

enamel, stain, shellac, varnish, polish, 

liquid filler and liquid lacquer base),’’

UN3470, PG II, would be added. 

46. A new entry ‘‘Paint, flammable, 

corrosive (including paint, lacquer, 

enamel, stain, shellac, varnish, polish, 

liquid filler and liquid lacquer base),’’

UN3469, PG I, II, and III, would be 

added. 

47. The entry ‘‘Paint including paint, 

lacquer, enamel, stain, shellac 

solutions, varnish, polish, liquid filler 

and liquid lacquer base,’’ UN1263, 

would be revised by adding the 

following Special provisions to the PG 

I, II, and III entries, respectively: 

—TP27 to specify that when this 

material is transported in an IM or UN 

Specification portable tank, a portable 

tank having a minimum test pressure 

of 4 bar (400 kPa) may be used 

provided the calculated test pressure 

is 4 bar or less based on the maximum 

allowable working pressure of the 

material, as defined in § 178.275 of 

the HMR, where the test pressure is 

1.5 times the maximum allowable 

working pressure. 

—TP28 to specify that when this 

material is transported in an IM or UN 

Specification portable tank, a portable 

tank having a minimum test pressure 

of 2.65 bar (265 kPa) may be used 

provided the calculated test pressure 

is 2.65 bar or less based on the 

maximum allowable working pressure 

of the material, as defined in 

§ 178.275 of the HMR, where the test 

pressure is 1.5 times the maximum 

allowable working pressure. 

—TP29 to specify that when this 

material is transported in an IM or UN 

Specification portable tank, a portable 

tank having a minimum test pressure 

of 1.5 bar (150.0 kPa) may be used 

provided the calculated test pressure 

is 1.5 bar or less based on the 

maximum allowable working pressure 

of the material, as defined in 

§ 178.275 of the HMR, where the test 

pressure is 1.5 times the maximum 

allowable working pressure. 

48. The entry ‘‘Paint or Paint related 

materials,’’ UN3066, would be revised 

by adding the following Special 

provisions to the PG II and III entries, 

respectively: 

—TP28 to specify that when this 

material is transported in an IM or UN 

Specification portable tank, a portable 

tank having a minimum test pressure 

of 2.65 bar (265 kPa) may be used 

provided the calculated test pressure 

is 2.65 bar or less based on the 

maximum allowable working pressure 

of the material, as defined in 

§ 178.275 of the HMR, where the test

maximum allowable working pressure 

of the material, as defined in 

§ 178.275 of the HMR, where the test 

pressure is 1.5 times the maximum 

allowable working pressure. 

49. A new entry, ‘‘Paint related 

material, corrosive, flammable 

(including paint thinning or reducing 

compound),’’ UN3470, PG II, would be 

added. 

50. A new entry, ‘‘Paint related 

material, flammable, corrosive 

(including paint thinning or reducing 

compound),’’ UN3469, PG I, II, and III 

would be added. 

51. The entry ‘‘Paint related material 

including paint thinning, drying, 

removing, or reducing compound,’’

UN1263, would be revised by adding 

the following Special provisions to the 

PG I, II, and III entries, respectively:

52. The entry ‘‘Plastic molding 

compound in dough, sheet or extruded 

rope form evolving flammable vapor, 

UN3314, PG III, would be revised by 

removing vessel stowage location A and 

adding location E in Column (10A), and 

by adding Vessel Stowage provisions 19, 

25 and proposed new Vessel Stowage 

provision 144 in Column (10B). 

53. The entry ‘‘Polymeric beads, 

expandable, evolving flammable vapor, 

UN2211, PG III, would be revised by 

removing stowage location A and 

adding location E in Column (10A), and 

by adding Vessel Stowage provisions 19, 

25 and proposed new Vessel Stowage 

provision 144 in Column (10B). 

54. For the entry ‘‘Propionic acid,’’

UN1848, the proper shipping name 

would be revised to read, ‘‘Propionic 

acid with not less than 10% and less 

than 90% acid by mass.’’ This revision 

appears as a ‘‘Remove/Add’’ in this 

rulemaking. 

55. A new entry, ‘‘Propionic acid with 

not less than 90% acid by mass,’’

UN3463, would be added. 

56. The entry ‘‘Rare gases mixtures, 

compressed,’’ UN1979, would be 

removed. 

57. The entry ‘‘Rare gases and oxygen 

mixtures, compressed,’’ UN1980, would 

be removed. 

58. The entry ‘‘Rare gases and 

nitrogen mixtures, compressed,’’

UN1981, would be removed. 

59. The proper shipping name 

‘‘Regulated medical waste,’’ UN3291, 

would be removed and a new proper 

shipping name ‘‘Regulated medical 

waste, n.o.s. or Clinical waste 

unspecified, n.o.s. or (BIO) Medical 

waste, n.o.s.,’’ UN3291, would be added 

in its place. 

60. For the international entry for 

‘‘Sulfur,’’ UN1350, the quantity 

limitations in Columns (9A) and (9B) 

would be revised to read 25 kg and 100 

kg, respectively. 

61. The entry 

‘‘Trimethylchlorosilane,’’ UN1298, PG 

II, would be revised by removing the 

reference to § 173.150 ‘‘Exceptions for 

Class 3 (flammable) and combustible 

liquids’’ in Column (8A). 

Also, see § 172.102 for additional 

HMT amendments. 

Appendix B to § 172.101 

Appendix B to § 172.101 lists Marine 

Pollutants regulated under the HMR. 

For the entry ‘‘Copper chloride’’ we are 

proposing to add the designation ‘‘PP’’

to indicate that copper chloride is a 

severe marine pollutant. We are also 

proposing to correct an oversight by 

removing the entries ‘‘Alcohol C–13—

C–15 poly (1–6) ethoxylate’’ and ‘‘1,2- 

Dichlorobenzene.’’ Removal of the entry 

‘‘Alcohol C–13—C–15 poly (1–6) 

ethoxylate’’ was overlooked in a final 

rule published under Docket HM–215G 

(69 FR 76044; December 20, 2004) and 

removal of the entry ‘‘1,2- 

Dichlorobenzene’’ was overlooked in a 

final rule published under Docket HM–

215D (66 FR 33316; June 21, 2001). 

Section 172.102 

Section 172.102 lists a number of 

special provisions applicable to the 

transportation of specific hazardous 

materials. Special provisions contain 

packaging provisions, prohibitions, and 

exceptions applicable to particular 

quantities or forms of hazardous 

materials. For consistency with 

international standards, we propose to 

amend § 172.102, Special provisions, as 

follows: 

• Special provision 15 specifies the 

types of materials and packaging 

requirements for chemical kits and first 

aid kits. We propose to revise Special 

provision 15 to list examples that may 

be described as ‘‘Chemical kits’’ and 

‘‘First aid kits.’’

• Special provision 47 specifies 

requirements for mixtures of nonhazardous solids and flammable liquids. 

In accordance with the UN 

Recommendations, Special provision 47 

would be revised to specify that, in 

addition to sealed packets, articles 

containing less than 10 mL of a Class 3 

Packing Group II or III liquid absorbed 

into a solid material would be excepted 

from the HMR provided there is no free 

liquid in the packet. 

• Special provision 77 applies to use 

of Division 5.1 subsidiary risk label. We 

propose to revise this special provision 

for consistency with the wording in the 

UN Recommendations. As proposed, 

Special provision 77 would no longer 

apply only to ‘‘domestic 

transportation.’’ Further, we propose to 

clarify that a Division 5.1 label is 

required if other oxidizing gases are 

present. Also, the provision would be 

applied to the entry ‘‘Compressed gas, 

n.o.s.,’’ UN1956, which is the most 

appropriate description for mixtures 

currently described as ‘‘Carbon dioxide 

and oxygen mixtures, compressed.’’ In 

this NPRM, we are proposing to remove 

the entry for ‘‘Carbon dioxide and 

oxygen mixtures, compressed,’’ which is 

consistent with its removal from the UN 

Recommendations. 

• Special provision 146 would be 

amended to authorize the domestic 

classification of a material as 

environmentally hazardous if it is 

designated as such by foreign competent 

authorities. The provision as currently 

worded may be interpreted to only 

allow such classification for 

international shipments. Due to current 

differences in criteria for the 

classification of environmentally 

hazardous substances world-wide, we 

believe the amended provision will 

afford additional flexibility to industry 

and reduce shipping costs by allowing 

both domestic and international 

shipments to be treated identically. 

• Special provision 147 applies to 

non-sensitized emulsions, suspensions 

and gels consisting primarily of a 

mixture of ammonium nitrate and fuel, 

intended to produce a Type E blasting 

explosive only after further processing 

prior to use. In accordance with the UN 

Recommendations, this special 

provision would be revised to specify 

the composition of mixtures for 

suspensions and gels and to specify 

these substances be tested in accordance 

with Test Series 8 of the UN Manual of 

Tests and Criteria. 

• Special provision 166 authorizes 

non-friable, tablet form calcium 

hypochlorite, dry or hydrated, to be 

transported as a Packing Group III 

material. In accordance with the UN 

Recommendations, we propose to revise 

Special provision 166 to remove the 

authorization for ‘‘hydrated’’ non-friable 

tablet forms of calcium hypochlorite to 

be transported as a PG III material. 


erjones on PROD1PC72 with PROPOSALS2
Federal Register / Vol. 71, No. 169 / Thursday, August 31, 2006 / Proposed Rules 51901 

• A new Special provision 175 would 

be added to require stabilization for 

certain substances when transported in 

concentrations of not more than 99%. 

• Special provision 101 would be 

removed. This special provision 

requires the name of the particular 

substance or article to be specified. With 

the introduction of the letter ‘‘G’’ in 

Column (1), which requires the n.o.s. 

and generic proper shipping names to 

be supplemented with the technical 

name of the hazardous material, Special 

provision 101 becomes obsolete. 

• A new Special provision A105 

would be added to specify the quantity 

of hazardous materials allowed in 

equipment or apparatus. 

Section 172.202 

Section 172.202 establishes 

requirements for shipping descriptions 

on shipping papers. Currently, the basic 

description of a hazardous material 

consists of the proper shipping name, 

hazard class, ID number and packing 

group, in that order. The HMR also 

authorize an alternative description 

sequence, which lists the identification 

number first, followed by the proper 

shipping name, hazard class, and 

packing group. Beginning January 1, 

2007, the alternative shipping 

description sequence will be mandatory 

on shipping documents prepared 

according to the ICAO Technical 

Instructions and the IMDG Code. In this 

NPRM, we propose to adopt the 

alternative shipping description 

sequence. We are also proposing a 2- 

year transition period to allow offerors 

sufficient time to convert to the new 

shipping description sequence. Readers 

are invited to comment on this proposal, 

especially on the length of the transition 

period. 

The description of a hazardous 

material on a shipping paper must 

include the total quantity of hazardous 

material (by mass or volume) covered by 

the description (see § 172.202(a)(5)). The 

majority of quantity limitations set forth 

for transportation by aircraft, in 

Columns (9A) and (9B), are ‘‘net’’

quantities. Section 175.75 limits the 

quantity of hazardous materials, 

expressed in net mass, aboard an 

aircraft. To facilitate compliance with 

the aircraft operator’s requirements, we 

are proposing that, for transportation by 

aircraft, the total quantity per package 

be shown, expressed as net mass, except 

as otherwise specified. For example: 

UN1263, Paint, 3, PG II, 5 fiberboard 

boxes x 5 L each 

Different size packages containing 

different quantities of the same 

hazardous material must be clearly 

identified. For example: 

UN 1263, Paint, 3, PG II, 5 fiberboard 

boxes x 5 L, 6 fiberboard boxes x 10 L 

Where the letter ‘‘G’’ follows the 

quantity in Column (9A) or (9B), the 

gross mass must be indicated, rather 

than the net quantity. 

Also, we are proposing the following 

additional requirements: 

—For empty uncleaned packaging, only 

the number and type of packaging 

must be shown; 

—For chemical kits and first aid kits, 

the total net mass of hazardous 

materials must be shown. Where a kit 

contains solids and/or liquids, the net 

mass of liquids within the kit is to be 

calculated on a 1 to 1 basis, i.e., 1 liter 

equals 1 kilogram; 

—For dangerous goods in machinery or 

apparatus, the individual total 

quantities of dangerous goods in 

solid, liquid or gaseous state, 

contained in the article must be 

shown; 

—For dangerous goods transported in a 

salvage packaging, an estimate of the 

quantity of dangerous goods per 

package must be shown; 

—For cylinders, the total quantity may 

be indicated by the number of 

cylinders, for example, ‘‘10 

cylinders;’’

—For items where ‘‘No Limit’’ is shown 

in Column (9A) or (9B) of the HMT, 

the quantity shown should be the net 

mass or volume of the material, 

except for UN2800, UN2807, UN3072, 

UN3166 and UN3173, where the 

quantity should be the gross mass of 

the article. 

Section 172.312 

Section 172.312 addresses marking 

requirements for liquid hazardous 

materials in non-bulk packagings. 

Specifically, the packaging must be 

marked with orientation arrows to 

indicate how the package should be 

oriented during transportation; the 

arrows indicate which end of the 

package is ‘‘up.’’ Currently the HMR 

require orientation markings only on a 

non-bulk combination package with 

inner packagings that contain a liquid 

hazardous material, unless specifically 

excepted. In this NPRM, we propose to 

revise paragraph (a) to require 

orientation markings on single 

packagings fitted with vents and on 

open cryogenic receptacles intended for 

the transport of refrigerated liquefied 

gases. Also, we propose to require the 

size of the marking to be proportioned 

so that it is clearly visible in relation to 

the size of the package, and to require 

the color of the arrows to be either black 

or red on a suitable contrasting 

background. Currently, the HMR do not 

specify either size or color 

requirements. Finally, we are proposing 

to add a new paragraph (c)(7) to except 

Class 7 radioactive materials in type A, 

IP–2, IP–3, B(U), B(M) or C packages 

from the orientation marking 

requirement. 

Sections 172.407 and 172.427 

Section 172.407 establishes 

specifications for package labels. 

Section 172.427 establishes 

requirements for the ORGANIC 

PEROXIDE label. In accordance with the 

UN Recommendations, we are 

proposing to revise the ORGANIC 

PEROXIDE label. The new label will 

reflect the fact that organic peroxides 

are highly flammable and will enable 

transport workers to readily distinguish 

peroxides from oxidizers with which 

they are generally not compatible. We 

also propose to allow labels meeting the 

specifications in effect on December 31, 

2006, to continue to be displayed until 

January 1, 2011 (see § 171.14). Adoption 

of the redesigned label will eliminate 

the current requirement in § 172.402 for 

a package containing an organic 

peroxide to bear a FLAMMABLE 

LIQUID subsidiary label in addition to 

the ORGANIC PEROXIDE primary 

hazard class label. 

Section 172.552 

Section 172.552 establishes specific 

requirements for the ORGANIC 

PEROXIDE placard. In accordance with 

the UN Recommendations, in paragraph 

(b), we are proposing to revise the 

ORGANIC PEROXIDE placard. The new 

placard will reflect the fact that organic 

peroxides are highly flammable and will 

enable transport workers to readily 

distinguish peroxides from oxidizers 

with which they are generally not 

compatible. We also propose to allow 

placards meeting the specifications in 

effect on December 31, 2006, to 

continue to be displayed until January 

1, 2011 (see § 171.14). 

Part 173 

Section 173.9 

Section 173.9 sets forth requirements 

for transporting cargo that has been 

fumigated or is undergoing fumigation. 

Such shipments must have a 

FUMIGANT marking. As specified in 

this section, the FUMIGANT marking 

includes an indication of the material 

used for fumigation and the date and 

time the fumigant was applied. 

Currently, transport vehicles or freight 

containers containing fumigated cargoes 

are not required to show the date the 

fumigant transport vehicle or freight 

container was ventilated to remove 

harmful concentration of fumigant gas. 


erjones on PROD1PC72 with PROPOSALS2
51902 Federal Register / Vol. 71, No. 169 / Thursday, August 31, 2006 / Proposed Rules 

To minimize the possibility of an 

individual entering a fumigated 

transport vehicle or freight container 

prematurely, we are proposing to add 

the date of ventilation on the 

FUMIGANT marking. We are also 

proposing to revise the specifications for 

the FUMIGANT marking to allow either 

red or black marking on a white 

background. Finally, we are proposing 

to revise the section for clarity. 

Sections 173.35, 173.120, 173.121, and 

Appendix H to Part 173 

Section 173.35 sets forth requirements 

for transporting hazardous materials in 

intermediate bulk containers (IBCs); 

§ 173.120 establishes classification 

criteria for flammable liquid (Class 3) 

materials; § 173.121 addresses packing 

group assignments for Class 3 materials; 

and Appendix H to Part 173 sets forth 

methods to test a material to determine 

its combustibility. We are proposing 

revisions in all of these sections to 

revise the upper limit for a PG III 

flammable liquid from 60.5 °C (141 °F) 

to 60 °C (140 °F). This is consistent with 

recent changes to the classification of 

flammable liquids based on the GHS 

and adoption into the UN 

Recommendations. PHMSA is also 

proposing a five-year transition period. 

Section 173.115 

The HMR define a Division 2.2 nonflammable gas as any material or 

mixture that ‘‘exerts in the packaging an 

absolute pressure of 280 kPa (40.6 psia) 

or greater at 20 °C (68 °F), * * *.’’ In 

paragraph (b)(1), we propose to add the 

phrase ‘‘or is a cryogenic liquid,’’ to 

clarify that a cryogenic liquid, whether 

or not it meets the definition of a 

Division 2.2 non-flammable gas, is 

subject to the HMR. This is consistent 

with the current requirements for 

cryogenic liquids in § 173.115(g). 

Currently, paragraph (k)(5) of this 

section requires aerosols containing 

Class 8, PG III materials to be assigned 

a Class 8 subsidiary hazard. We are 

proposing to amend paragraph (k)(5) to 

specify that aerosols containing Class 8, 

PG II or PG III materials must be 

assigned a Class 8 subsidiary hazard. 

Section 173.124 

Section 173.124 establishes 

classification criteria for Division 4.1 

(flammable solid), Division 4.2 

(spontaneously combustible), and 

Division 4.3 (dangerous when wet) 

materials. We are proposing to require 

mixtures of oxidizing substances 

containing 5.0% or more combustible 

organic substances to be subject to the 

self-reactive substance classification 

procedure. This will ensure that 

oxidizing substances containing 5.0% or 

more of combustible organic substances 

are also tested for their ability to selfreact and to ensure that in such 

instances, these substances are 

appropriately classed for their selfreactive hazard. 

Section 173.133 

Section 173.133 establishes criteria 

for assignment of packing groups to 

poisonous (Division 6.1) materials. We 

are proposing to amend the toxicity 

criteria for consistency with the toxicity 

criteria adopted in the UN 

Recommendations on the basis of the 

limits established in the GHS. As a 

result, some materials that were not 

previously regulated under the HMR 

will be regulated as Division 6.1, 

Packing Group III; some materials 

currently regulated as Division 6.1, 

Packing Group I or II will be assigned 

to a different packing group; and some 

materials that were previously regulated 

as Division 6.1, Packing Group III will 

not be subject to regulation under the 

HMR. PHMSA is proposing a five year 

transition period. 

The effect of these changes to packing 

group assignments for Division 6.1 

materials is summarized as follows: 

Material properties Current PG 

assignment 

Proposed PG 

assignment 

Oral LD50 > 200, ≤ 300 (Solid) ............................................................................................................................ Not regulated ... III. 

Oral LD50 > 300, ≤ 500 (Liquid) .......................................................................................................................... III ...................... Not regulated. 

Dermal LD50 > 40, ≤ 50 ....................................................................................................................................... II ....................... I. 

Inhalation toxicity by dusts and mists LC50 > 0.2, ≤ 0.5 ..................................................................................... I ........................ II. 

Inhalation toxicity by dusts and mists LC50 > 4, ≤ 10 ......................................................................................... III ...................... Not regulated. 

Sections 173.134 and 173.197 

These sections are revised by 

replacing the wording ‘‘Regulated 

medical waste’’ with the wording 

‘‘Regulated medical waste or clinical 

waste or (bio) medical waste.’’

Section 173.136 

Currently, the HMR define ‘‘corrosive 

material’’ to mean ‘‘a liquid or solid that 

causes full thickness destruction of 

human skin at the site of contact within 

a specified period of time. A liquid that 

has a severe corrosion rate on steel or 

aluminum based on the criteria in 

§ 173.137(c)(2) is also a corrosive 

material.’’ Certain solids with a low 

melting point may become liquid during 

transportation, and others may be 

intentionally heated above their melting 

point and transported as a liquid in the 

molten state. We believe that the Class 

8 definition should apply equally to 

liquids and to solids offered for 

transportation or transported in a liquid 

state. Therefore, we are proposing to 

revise the definition of a ‘‘corrosive 

material’’ in paragraph (a), to include a 

solid material that is offered for 

transportation or transported as a liquid 

and has a severe corrosion rate on steel 

or aluminium. 

Also, we are proposing to remove the 

grandfather provision in § 173.136(d) on 

the basis that it is no longer necessary 

because tests other than the one 

specified in the UN Manual of Tests and 

Criteria will be authorized. See the 

§ 173.137 preamble discussion below. 

Section 173.137 

Section 173.137 establishes packing 

group criteria for corrosive (Class 8) 

materials. In a final rule published 

under Docket HM–215G (69 FR 76155; 

December 20, 2004), we revised the 

language in paragraph (c)(2) mandating 

the corrosion test in the UN Manual of 

Tests and Criteria as the only acceptable 

test method for determining the 

corrosivity of a material. That was not 

our intent. In this NPRM, we are 

proposing to revise paragraph (c)(2) to 

specify that corrosivity may be 

determined in accordance with methods 

described in the UN Manual of Tests 

and Criteria, as well as other equivalent 

methods such as those described in 

ASTM G 31–72. 

Section 173.159 

Section 173.159 establishes 

transportation requirements for wet 

electric storage batteries. In accordance 

with the ICAO Technical Instructions, 

we are proposing to revise paragraphs 

(a), (c)(1), (c)(2), (c)(4), (c)(5), (d)(1) and 

(e)(2) to clarify that batteries may be 

protected against short circuits by the 

use of non-conductive caps that cover 

the entire terminal(s). 


erjones on PROD1PC72 with PROPOSALS2
Federal Register / Vol. 71, No. 169 / Thursday, August 31, 2006 / Proposed Rules 51903 

Section 173.166 

Section 173.166 establishes 

transportation requirements for air bag 

inflators, air bag modules, and seat-belt 

pretensioners. Currently, paragraph 

(d)(1) excepts from the HMR air bag 

modules and seat-belt pretensioners 

approved by the Associate 

Administrator and installed in a motor 

vehicle or a completed motor vehicle 

component. We propose to revise 

paragraph (d)(1) to expand the 

exception to include air bag modules 

and seat-belt pretensioners installed in 

other means of conveyance, such as 

boats and aircraft, or their components. 

Section 173.187 

Section 173.187 establishes 

transportation requirements for 

pyrophoric solids, metals, or alloys, not 

otherwise specified (n.o.s.). We propose 

to revise this section for clarity and to 

correct an oversight by adding 4A steel 

boxes to the list of authorized 

packagings for pyrophoric solids, metals 

or alloys, n.o.s. 

Section 173.216 

Section 173.216 establishes 

transportation requirements for blue, 

brown, or white asbestos. Paragraph (c) 

of this section specifies packaging 

requirements for these materials. In 

paragraph (c), we are proposing to 

require bags or other non-rigid packages 

containing asbestos to be transported in 

rigid outer packages or closed freight 

containers. 

Section 173.220 

Section 173.220 establishes 

transportation requirements for internal 

combustion engines, self-propelled 

vehicles, mechanical equipment 

containing internal combustion engines, 

and battery powered vehicles and 

equipment. For transportation by 

aircraft, the HMR impose a pressure 

limit of not more than 5% of the 

maximum allowable working pressure 

in any part of the system between the 

pressure receptacle and the shut off 

valve of a flammable gas powered 

vehicle. We are proposing to revise 

paragraph (b)(2)(ii)(B)(3) to specify that 

the pressure limit imposed applies to 

the entire closed system and that the 

maximum pressure allowed is 290 psig 

(2000 kPa). Also, consistently with the 

ICAO Technical Instructions, we are 

proposing to revise paragraphs (c) and 

(d) to clarify that batteries may be 

protected against short circuits by the 

use of non-conductive caps that cover 

the entire terminal(s). 

Section 173.222 

This section establishes requirements 

for hazardous materials in equipment, 

machinery and apparatus. Because of 

the addition of Special provision A105 

in the HMT, the shipping paper 

requirements in paragraph (d) no longer 

apply to transportation by aircraft. We 

are proposing to revise paragraph (d) 

accordingly. 

Section 173.224 

Section 173.224 establishes packaging 

and control and emergency 

temperatures for self-reactive materials. 

The Self-Reactive Materials Table in 

paragraph (b)(7) of this section specifies 

self-reactive materials authorized for 

transportation without first being 

approved for transportation by the 

Associate Administrator for Hazardous 

Materials Safety and requirements for 

transporting these materials. In 

paragraph (b)(7), we propose to add a 

new entry ‘‘Acetone-pyrogallol 

copolymer 2-diazo-1-naphthol-5- 

sulphonate’’ to the Self-Reactive 

Materials Table. 

Section 173.230 

We are proposing to add a new 

packaging section (§ 173.230) for the 

transportation of ‘‘Fuel cell cartridges 

containing flammable liquids, UN 

3473’’ including methanol or methanol/ 

water solutions. For consistency with 

the ICAO Technical Instructions, we are 

proposing to require fuel cell cartridges 

containing flammable liquids, other 

than those packaged with equipment, to 

be packaged in specification packagings 

for all modes of transportation. Fuel cell 

cartridges packaged in or with 

equipment must be packaged in strong 

outer packagings. 

Section 173.306 

This section establishes transportation 

requirements for limited quantities of 

compressed gases. Paragraph (i) of this 

section excepts aerosols with capacities 

under 50 mL (1.7 oz) and pressures not 

exceeding 970 kPa (141 psig) at 55 °C 

(131 °F) from all HMR requirements. In 

this NPRM, we propose to expand this 

exception to aerosols with capacities of 

less than 50 mL (1.7 oz) and pressures 

of up to 290 psig (2000 kPa) provided 

the packagings conform to the general 

packaging requirements of § 173.24. The 

proposed amendment is not consistent 

with provisions of the UN 

Recommendations or the ICAO 

Technical Instructions, which do not 

limit the pressure within the aerosol or 

small receptacle. We are not convinced 

that aerosols should be excepted from 

all regulation when the pressure in the 

container exceeds 290 psig (2000 kPa). 

Because the aerosols and small gas 

receptacles would not be subject to the 

shipping paper, package marking, or 

labeling requirements, a carrier might be 

unaware of the potential risks. In 

addition, to avoid confusion and further 

clarify the intent of this exception, we 

are proposing to revise paragraph (i) to 

specify that the 50 mL exception for 

aerosols does not apply to self-defense 

sprays. It was not our intent to authorize 

the use of this exception for self-defense 

sprays. 

Also, we are proposing to add a new 

paragraph (j) to alert readers to 

additional exceptions for compressed 

gases in § 173.307. 

Part 175 

Section 175.10 

Currently, safety matches or a lighter 

intended for use by a passenger or crew 

member are excepted from the HMR. In 

accordance with the ICAO Technical 

Instructions, in this NPRM, we are 

proposing to revise paragraph (a)(2) to 

limit the number of safety matches that 

may be carried on one’s person or in 

carry-on baggage by a passenger or 

crewmember to one packet. 

Section 175.78 

Section 175.78 establishes 

requirements for stowing hazardous 

materials on an airplane. We propose to 

amend paragraph (c)(4) to clarify which 

explosive materials may be stowed 

together aboard an aircraft and to 

remove existing stowage references for 

explosive materials not authorized for 

transportation aboard aircraft under any 

circumstances. 

Part 176 

Section 176.76 

Section 176.76 establishes 

requirements for vessel transportation of 

transport vehicles, freight containers, 

and portable tanks containing hazardous 

materials. Paragraph (f) includes 

requirements for portable tanks 

containing flammable liquids or gases. 

Consistently with recent changes to the 

classification of flammable liquids 

based on the GHS and adopted into the 

UN Recommendations discussed 

elsewhere in this preamble, we are 

proposing to revise paragraph (f)(2) to 

specify the new upper limit for a PG III 

flammable liquid to be 60 °C (140 °F). 

Section 176.83 

Section 176.83 establishes segregation 

requirements for hazardous materials 

transported by vessel. We are proposing 

to revise paragraph (a)(4) to identify 

materials of different hazard classes that 

do not react dangerously with each 


erjones on PROD1PC72 with PROPOSALS2
51904 Federal Register / Vol. 71, No. 169 / Thursday, August 31, 2006 / Proposed Rules 

other and, therefore, do not need to be 

segregated. 

Section 176.84 

Section 176.84 contains additional 

stowage and segregation requirements 

for hazardous materials on cargo and 

passenger vessels. Consistently with the 

2004 Edition of the IMDG Code, 

incorporating Amendment 33–06, in the 

paragraph (b) Table of provisions, we 

are proposing to add a new Code ‘‘144.’’

Code ‘‘144’’ would be added to the 

entries ‘‘Plastic molding compound in 

dough, sheet or extruded rope from 

evolving flammable vapor,’’ UN3314, 

and ‘‘Polymeric beads expandable, 

evolving flammable vapor,’’ UN2211, to 

specify these materials must be 

mechanically ventilated in accordance 

with SOLAS regulation II–2/19 (IBR; see 

§ 171.7 of this subchapter) for 

flammable liquids with a flashpoint 

below 23 °C (73 °F) when stowed under 

deck. 

Also, we are proposing to add a new 

note ‘‘2’’ following the Table. Note ‘‘2’’

provides an exception from the 

segregation requirements for Class 8, PG 

II and III materials, provided the 

substances do not react dangerously 

with each other and the quantities per 

package do not exceed 30 L (7.8 gallons) 

for liquids and 30 kg (66 lbs.) for solids. 

We are also proposing to revise Codes 

‘‘26,’’ ‘‘27,’’ ‘‘52,’’ and ‘‘53’’ to add the 

new proposed note ‘‘2.’’ These 

provisions are consistent with the IMDG 

Code. 

Part 178 

Section 178.274 

Section 178.274 establishes design, 

manufacturing, and test requirements 

for UN portable tanks. Currently, a 

prototype UN portable tank must be 

shown capable of absorbing the forces 

resulting from an impact not less than 

four times the maximum permissible 

gross weight of the fully loaded portable 

tank at a duration that is typical of the 

mechanical shocks experienced in rail 

transportation. Several standards 

describing methods acceptable for 

performing the impact test were 

previously listed in the UN 

Recommendations (6.7.3.15). The 

Fourteenth revised edition of the UN 

Recommendations includes a dynamic 

longitudinal impact test for portable 

tanks. All procedures, test requirements, 

processing and analysis of data are 

found in Section 41 of Addendum 2 to 

the UN Recommendations. 

We propose to revise paragraph (j)(6) 

to require each UN portable tank design 

type be subjected to a dynamic 

longitudinal impact test to prove the 

ability of the portable tank to withstand 

the effects of a longitudinal impact. This 

requirement would take effect on 

January 1, 2008, and is consistent with 

the international requirements. UN 

portable tanks impact-tested based on 

the criteria in effect on October 1, 2005, 

would not need to be retested. 

Section 178.602 

Section 178.602 establishes 

requirements for the preparation of 

packagings for testing to ascertain that 

the packaging conforms to the design 

requirements of the applicable 

specification. Currently, for the 

preparation of bags for the drop and 

stacking tests, paragraph (b) requires 

bags to be filled to the maximum mass 

at which they may be used. We are 

proposing to revise paragraph (b) to 

clarify that the preparation of bags for 

the drop and stacking tests only applies 

to bags containing solids. 

Section 178.810 

Section 178.810 establishes 

requirements for performing the drop 

test for IBCs. We are proposing to revise 

paragraph (b)(1) to clarify that metal, 

rigid plastic, and composite IBCs must 

be filled to not less than 95% of their 

maximum capacity when conducting 

drop tests for solids, and not less than 

98% of their maximum capacity for 

liquids. Similarly, in paragraph (b)(2), 

we are proposing to require fiberboard 

and wooden IBCs to be filled with a 

solid material to not less than 95% of 

their maximum capacity. Also, we are 

proposing to add a new paragraph (b)(3) 

to require filling flexible IBCs to the 

maximum permissible gross mass and 

even distribution of the contents. 

Part 180 

Section 180.352 

Section 180.352 establishes 

requirements for retesting and 

inspection of IBCs to ensure that they 

continue to conform to the applicable 

specification. We are proposing to revise 

paragraph (b) to specify that each IBC 

intended to contain solids that are 

loaded or discharged under pressure or 

intended to contain liquids must be 

tested in accordance with the 

leakproofness test prescribed in 

§ 178.813 prior to its first use in 

transportation. For this test, the IBC is 

not required to have its closures fitted. 

These additions incorporate 

clarifications adopted in the Fourteenth 

revised edition of the UN 

Recommendations. We are proposing to 

editorially revise paragraph (g) for 

clarity. 

VI. Regulatory Analyses and Notices 

A. Statutory/Legal Authority for This 

Rulemaking 

This proposed rule is published under 

the following statutory authorities: 

1. 49 U.S.C. 5103(b) authorizes the 

Secretary of Transportation to prescribe 

regulations for the safe transportation, 

including security, of hazardous 

material in intrastate, interstate, and 

foreign commerce. This proposed rule 

amends regulations to maintain 

alignment with international standards 

by incorporating various amendments, 

including changes to proper shipping 

names, hazard classes, packing groups, 

special provisions, packaging 

authorizations, air transport quantity 

limitations and vessel stowage 

requirements. To this end, as discussed 

in detail earlier in this preamble, the 

proposed rule amends the HMR to more 

fully align them with the biennial 

updates of the UN Recommendations, 

the IMDG Code and the ICAO Technical 

Instructions; this will facilitate the 

transport of hazardous materials in 

international commerce. 

2. 49 U.S.C. 5120(b) authorizes the 

Secretary of Transportation to ensure 

that, to the extent practicable, 

regulations governing the transportation 

of hazardous materials in commerce are 

consistent with standards adopted by 

international authorities. This rule 

proposes to amend the HMR to maintain 

alignment with international standards 

by incorporating various amendments to 

facilitate the transport of hazardous 

material in international commerce. To 

this end, as discussed in detail earlier in 

this preamble, the rule proposes to 

incorporate changes into the HMR based 

on the Fourteenth revised edition of the 

UN Recommendations, Amendment 33 

to the IMDG Code, and the 2007–2008 

ICAO Technical Instructions, which 

become effective January 1, 2007. The 

continually increasing amount of 

hazardous materials transported in 

international commerce warrants the 

harmonization of domestic and 

international requirements to the 

greatest extent possible. Harmonization 

serves to facilitate international 

transportation; at the same time, 

harmonization ensures the safety of 

people, property, and the environment 

by reducing the potential for confusion 

and misunderstanding that could result 

if shippers and transporters were 

required to comply with two or more 

conflicting sets of regulatory 

requirements. While the intent of this 

rulemaking is to align the HMR with 

international standards, we review and 

consider each amendment on its own 

merit based on its overall impact on 


erjones on PROD1PC72 with PROPOSALS2
Federal Register / Vol. 71, No. 169 / Thursday, August 31, 2006 / Proposed Rules 51905 

transportation safety and the economic 

implications associated with its 

adoption into the HMR. Our goal is to 

harmonize without sacrificing the 

current HMR level of safety and without 

imposing undue burdens on the 

regulated public. Thus, as discussed in 

detail earlier in this preamble, there are 

several instances where we elected not 

to adopt a specific provision of the UN 

Recommendations, the IMDG Code or 

the ICAO Technical Instructions; 

further, we are maintaining a number of 

current exceptions for domestic 

transportation that should minimize the 

compliance burden on the regulated 

community. 

B. Executive Order 12866 and DOT 

Regulatory Policies and Procedures 

This proposed rule is not considered 

a significant regulatory action under 

section 3(f) of Executive Order 12866 

and, therefore, was not reviewed by the 

Office of Management and Budget. The 

proposed rule is not considered a 

significant rule under the Regulatory 

Policies and Procedures of the 

Department of Transportation [44 FR 

11034]. This proposed rule applies to 

offerors and carriers of hazardous 

materials, such as chemical 

manufacturers, chemical users and 

suppliers, packaging manufacturers, 

distributors, battery manufacturers, 

radiopharmaceutical companies, and 

training companies. Benefits resulting 

from the adoption of the amendments in 

this proposed rule include enhanced 

transportation safety resulting from the 

consistency of domestic and 

international hazard communications 

and continued access to foreign markets 

by U.S. manufacturers of hazardous 

materials. 

The majority of amendments in this 

proposed rule should result in cost 

savings and ease the regulatory 

compliance burden for shippers engaged 

in domestic and international 

commerce, including trans-border 

shipments within North America. 

We propose a delayed effective date 

and a one-year transition period to 

allow for training of employees and to 

ease any burden on entities affected by 

the amendments. The total net increase 

in costs to businesses in implementing 

the proposed rule is considered to be 

minimal. The costs are the result of 

reprogramming shipping paper 

computer programs, replacement of preprinted forms for firms that do not use 

automated systems, and changes to 

package markings and labels. Initial 

start-up and inventory costs would 

result from these changes; however, the 

costs would be offset by greater longterm savings of conformance with one 

set of regulations and a one year 

transition period. A regulatory 

evaluation is available for review in the 

public docket for this rulemaking. 

C. Executive Order 13132 

This proposed rule has been analyzed 

in accordance with the principles and 

criteria contained in Executive Order 

13132 (‘‘Federalism’’). This proposed 

rule preempts State, local and Indian 

tribe requirements but does not propose 

any regulation that has substantial 

direct effects on the States, the 

relationship between the national 

government and the States, or the 

distribution of power and 

responsibilities among the various 

levels of government. Therefore, the 

consultation and funding requirements 

of Executive Order 13132 do not apply. 

The Federal hazardous material 

transportation law, 49 U.S.C. 5101–

5128, contains an express preemption 

provision (49 U.S.C. 5125(b)) that 

preempts State, local, and Indian tribe 

requirements on certain covered 

subjects. Covered subjects are: 

(1) The designation, description, and 

classification of hazardous material; 

(2) The packing, repacking, handling, 

labeling, marking, and placarding of 

hazardous material; 

(3) The preparation, execution, and 

use of shipping documents related to 

hazardous material and requirements 

related to the number, contents, and 

placement of those documents; 

(4) The written notification, 

recording, and reporting of the 

unintentional release in transportation 

of hazardous material; and 

(5) The design, manufacture, 

fabrication, inspection, marking, 

maintenance, recondition, repair, or 

testing of a packaging or container 

represented, marked, certified, or sold 

as qualified for use in transporting 

hazardous material in commerce. 

This proposed rule addresses covered 

subject items (1), (2), (3), and (5) above 

and preempts State, local, and Indian 

tribe requirements not meeting the 

‘‘substantively the same’’ standard. This 

proposed rule is necessary to 

incorporate changes adopted in 

international standards, effective 

January 1, 2007. If the changes in this 

proposed rule are not adopted in the 

HMR, U.S. companies, including 

numerous small entities competing in 

foreign markets, would be at an 

economic disadvantage. These 

companies would be forced to comply 

with a dual system of regulations. The 

changes in this proposed rulemaking are 

intended to avoid this result. Federal 

hazardous materials transportation law 

provides at section 5125(b)(2) that, if 

DOT issues a regulation concerning any 

of the covered subjects, DOT must 

determine and publish in the Federal 

Register the effective date of Federal 

preemption. The effective date may not 

be earlier than the 90th day following 

the date of issuance of the final rule and 

not later than two years after the date of 

issuance. PHMSA proposes the effective 

date of Federal preemption be 90 days 

from publication of a final rule in this 

matter in the Federal Register. 

D. Executive Order 13175 

This proposed rule was analyzed in 

accordance with the principles and 

criteria contained in Executive Order 

13175 (‘‘Consultation and Coordination 

with Indian Tribal Governments’’). 

Because this proposed rule does not 

have tribal implications, does not 

impose substantial direct compliance 

costs, and is required by statute, the 

funding and consultation requirements 

of Executive Order 13175 do not apply. 

E. Regulatory Flexibility Act, Executive 

Order 13272, and DOT Procedures and 

Policies 

The Regulatory Flexibility Act (5 

U.S.C. 601 et seq.) requires an agency to 

review regulations to assess their impact 

on small entities, unless the agency 

determines that a rule is not expected to 

have a significant impact on a 

substantial number of small entities. 

This proposed rule facilitates the 

transportation of hazardous materials in 

international commerce by providing 

consistency with international 

standards. This proposed rule applies to 

offerors and carriers of hazardous 

materials, some of whom are small 

entities, such as chemical users and 

suppliers, packaging manufacturers, 

distributors, battery manufacturers, and 

training companies. As discussed above, 

under Executive Order 12866, the 

majority of amendments in this 

proposed rule should result in cost 

savings and ease the regulatory 

compliance burden for shippers engaged 

in domestic and international 

commerce, including trans-border 

shipments within North America. 

Many companies will realize 

economic benefits as a result of these 

amendments. Additionally, the changes 

effected by this final rule will relieve 

U.S. companies, including small entities 

competing in foreign markets, from the 

burden of complying with a dual system 

of regulations. Therefore, I certify that 

these amendments will not, if 

promulgated, have a significant 

economic impact on a substantial 

number of small entities. 

This proposed rule has been 

developed in accordance with Executive 


erjones on PROD1PC72 with PROPOSALS2
51906 Federal Register / Vol. 71, No. 169 / Thursday, August 31, 2006 / Proposed Rules 

Order 13272 (‘‘Proper Consideration of 

Small Entities in Agency Rulemaking’’) 

and DOT’s procedures and policies to 

promote compliance with the 

Regulatory Flexibility Act to ensure that 

potential impacts of draft rules on small 

entities are properly considered. 

F. Paperwork Reduction Act 

Under the Paperwork Reduction Act 

of 1995, no person is required to 

respond to a collection of information 

unless it displays a valid Office of 

Management and Budget (OMB) control 

number. Section 1320.8(d), Title 5, Code 

of Federal Regulations requires that 

PHMSA provide interested members of 

the public and affected agencies an 

opportunity to comment on information 

collection and recordkeeping requests. 

PHMSA currently has two approved 

information collections affecting this 

proposed rule: OMB Control Number 

2137–0557, ‘‘Approvals for Hazardous 

Materials’’ with 25,605 burden hours 

and $562,837.40 burden costs; and OMB 

Control Number 2137–0613, 

‘‘Subsidiary Hazard Class & Number/ 

Type of Packagings’’ with 63,309 burden 

hours and $216,705 burden costs. 

This rule proposes minor editorial 

changes. However, there is no net 

increase in burden for OMB Control 

Number 2137–0557 or OMB Control 

Number 2137–0613. We estimate the 

total information collection and 

recordkeeping burden as follows: 

‘‘Approvals for Hazardous Materials’’

OMB Number: 2137–0557. 

Total Annual Number of 

Respondents: 3,523. 

Total Annual Responses: 3,874.8. 

Total Annual Burden Hours: 25,605. 

Total Annual Burden Cost: 

$562,837.40. 

‘‘Subsidiary Hazard Class & Number/ 

Type of Packagings’’

OMB Number: 2137–0613. 

Total Annual Number of 

Respondents: 250,000. 

Total Annual Responses: 6,337,500. 

Total Annual Burden Hours: 17,604. 

Total Annual Burden Cost: $216,705. 

Total First Year Burden Hours: 

45,705. 

Total First Year Burden Cost: 

$1,115,992. 

Requests for a copy of this 

information collection should be 

directed to Deborah Boothe or T. Glenn 

Foster, Office of Hazardous Materials 

Standards (PHH–10), Pipeline and 

Hazardous Materials Safety 

Administration, Room 8422, 400 

Seventh Street, SW., Washington, DC 

20590–0001, telephone (202) 366–8553. 

G. Regulation Identifier Number (RIN) 

A regulation identifier number (RIN) 

is assigned to each regulatory action 

listed in the Unified Agenda of Federal 

Regulations. The Regulatory Information 

Service Center publishes the Unified 

Agenda in April and October of each 

year. The RIN contained in the heading 

of this document can be used to crossreference this action with the Unified 

Agenda. 

H. Unfunded Mandates Reform Act 

This proposed rule does not impose 

unfunded mandates under the 

Unfunded Mandates Reform Act of 

1995. It does not result in costs of 

$120.7 million or more to either State, 

local or tribal governments, in the 

aggregate, or to the private sector, and 

is the least burdensome alternative that 

achieves the objective of the rule. 

I. Environmental Assessment 

The National Environmental Policy 

Act of 1969 (NEPA) requires Federal 

agencies to consider the consequences 

of major Federal actions and prepare a 

detailed statement on actions 

significantly affecting the quality of the 

human environment. We developed an 

assessment to determine the effects of 

these revisions on the environment and 

whether a more comprehensive 

environmental impact statement may be 

required. Consistency in the regulations 

for the transportation of hazardous 

materials aids in shipper understanding 

of the requirements and permits 

shippers to more easily comply with 

safety regulations and avoid the 

potential for environmental damage or 

contamination. Our findings tentatively 

conclude that there are no significant 

environmental impacts associated with 

this proposed rule. Interested parties, 

however, are invited to review the 

Environmental Assessment available in 

the docket and to comment on what 

environmental impact, if any, the 

proposed regulatory changes would 

have. 

J. Privacy Act 

Anyone is able to search the 

electronic form of any written 

communications and comments 

received into any of our dockets by the 

name of the individual submitting the 

document (or signing the document, if 

submitted on behalf of an association, 

business, labor union, etc.). You may

Statement in the Federal Register

15 This entry applies to ‘‘Chemical 

kits’’ and ‘‘First aid kits’’ containing one 

or more compatible items of hazardous 

materials in boxes, cases, etc. that, for 

example, are used for medical, 

analytical, diagnostic, testing, or repair 

purposes. For transportation by aircraft, 

materials forbidden for transportation 

by passenger aircraft or cargo aircraft 

may not be included in the kits. 

Chemical kits and first aid kits are 

excepted from the specification 

packaging requirements of this 

subchapter when packaged in 

combination packagings. Chemical kits 

and first aid kits are also excepted from 

the labeling and placarding 

requirements of this subchapter, except 

when offered for transportation or 

transported by air. Chemical and first 

aid kits may be transported in 

accordance with the consumer 

commodity and ORM exceptions in 

§ 173.156, provided they meet all 

required conditions. Kits that are carried 

on board transport vehicles for first aid 

or operating purposes are not subject to 

the requirements of this subchapter. 

* * * * * 

47 Mixtures of solids that are not 

subject to this subchapter and 

flammable liquids may be transported 

under this entry without first applying 

the classification criteria of Division 4.1, 

provided there is no free liquid visible 

at the time the material is loaded or at 

the time the packaging or transport unit 

is closed. Except when the liquids are 

fully absorbed in solid material 

contained in sealed bags, each 

packaging must correspond to a design 

type that has passed a leakproofness test 

at the Packing Group II level. Small 

inner packagings consisting of sealed 

packets and articles containing less than 

10 mL of a Class 3 liquid in Packing 

Group II or III absorbed onto a solid 

material are not subject to this 

subchapter provided there is no free 

liquid in the packet or article. 

* * * * * 

77 Mixtures containing not more 

than 23.5% oxygen by volume may be 

transported under this entry when no 

other oxidizing gases are present. A 

Division 5.1 subsidiary risk label is not 

required for any concentrations within 

this limit. 

* * * * * 

146 This description may be used 

for a material that poses a hazard to the 

environment but does not meet the 

definition for a hazardous waste or a 

hazardous substance, as defined in 

§ 171.8 of this subchapter, or any hazard 

class, as defined in Part 173 of this 

subchapter, if it is designated as 

environmentally hazardous by another 

Competent Authority. This provision 

may be used for both domestic and 

international shipments. 

147 This entry applies to nonsensitized emulsions, suspensions, and 

gels consisting primarily of a mixture of 

ammonium nitrate and fuel, intended to 

produce a Type E blasting explosive 

only after further processing prior to 

use. The mixture for emulsions typically 

has the following composition: 60–85% 

ammonium nitrate; 5–30% water; 2–8% 

fuel; 0.5–4% emulsifier or thickening 

agent; 0–10% soluble flame 

suppressants; and trace additives. Other 

inorganic nitrate salts may replace part 

of the ammonium nitrate. The mixture 

for suspensions and gels typically has 

the following composition: 60–85% 

ammonium nitrate; 0–5% sodium or 

potassium perchlorate; 0–17% 

hexamine nitrate or monomethylamine 

nitrate; 5–30% water; 2–15% fuel; 0.5–

4% thickening agent; 0–10% soluble 

flame suppressants; and trace additives. 

Other inorganic nitrate salts may replace 

part of the ammonium nitrate. These 

substances must satisfactorily pass Test 

Series 8 of the UN Manual of Tests and 

Criteria, Part I, Section 18 (IBR, see 

§ 171.7 of this subchapter), and may not 

be classified and transported unless 

approved by the Associate 

Administrator.

dangerous goods contained in one 

package, excluding magnetic material, 

must not exceed the following: 

a. 1 kg (2.2 pounds) in the case of 

solids; 

b. 0.5 L (0.1 gallons) in the case of 

liquids; 

c. 0.5 kg (1.1 pounds) in the case of 

Division 2.2 gases; or 

d. any combination thereof. 

8. In § 172.202, paragraphs (a) and (b) 

are revised to read as follows: 

§ 172.202 Description of hazardous 

material shipping papers. 

(a) The shipping description of a 

hazardous material on the shipping 

paper must include: 

(1) The identification number 

prescribed for the material as shown in 

Column (4) of the § 172.101 table; 

(2) The proper shipping name 

prescribed for the material in Column 

(2) of the § 172.101 table; 

(3) The hazard class or division 

number prescribed for the material, as 

shown in Column (3) of the § 172.101 

table. Except for combustible liquids, 

the subsidiary hazard class(es) or 

subsidiary division number(s) must be 

entered in parentheses immediately 

following the primary hazard class or 

division number. 

In addition—

(i) The words ‘‘Class’’ or ‘‘Division’’

may be included preceding the primary 

and subsidiary hazard class or division 

numbers. 

(ii) The hazard class need not be 

included for the entry ‘‘Combustible 

liquid, n.o.s.’’

(iii) For domestic shipments, primary 

and subsidiary hazard class or division 

names may be entered following the 

numerical hazard class or division, or 

following the basic description. 

(4) The packing group in Roman
