I. Background

By notice of proposed rulemaking (NPRM) published August 31, 2006, the Pipeline and Hazardous Materials Safety Administration (PHMSA, we) published proposed revisions to the hazard communication, classification, and packaging requirements of the Hazardous Materials Regulations (HMR), 49 CFR parts 171-180, to align with updates and revisions to the United Nations Recommendations on the Transport of Dangerous Goods (UN Recommendations), the International Maritime Dangerous Goods (IMDG) Code and the International Civil Aviation Organization (ICAO) Technical Instructions for the Transport of Dangerous Goods by Air. The UN Recommendations are amended and updated biennially by the UN Committee of Experts on the Transport of Dangerous Goods and on the Globally Harmonized System of Classification and Labeling of Chemicals and serve as the basis for national, regional, and international modal regulations, including the IMDG Code, and the 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 facilitates international trade by minimizing the costs and other burdens of complying with multiple or inconsistent safety requirements for transportation of hazardous materials to and from the United States. By facilitating compliance, harmonization also tends to enhance safety for international movements, but only if the international standards themselves provide an appropriate level of safety. To that end, PHMSA actively participates in the development of international standards for the transportation of hazardous materials, frequently advocating the adoption in international standards of particular HMR requirements. When considering the adoption of international standards under the HMR, 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.

To maintain alignment of the HMR with international requirements, in this final rule, we are incorporating changes into the HMR based on the Fourteenth revised edition of the UN Recommendations and UN Manual of Tests and Criteria, 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.

Commenters were supportive of PHMSA's efforts to harmonize the HMR with international standards. Many of the proposals in the NPRM are fully supported by commenters, while others received little or no comment; these amendments are adopted as proposed. Several comments were beyond the scope of this rulemaking and are not addressed in this final rule.

In the NPRM, we requested comments on whether certain amendments should be tied to a sunset provision. We received six comments (GPS, IME, NTTC, AP&C, ATA, and NPCA) opposing the idea of a sunset provision. We agree with the commenters that for an international harmonization rulemaking, sunsetting some or all of the regulatory provisions is not appropriate. Therefore, we are not adopting a sunset provision for the amendments in this final rule. Other comments are discussed in the Section-by-Section Review.

II. Overview

A. Amendments Adopted in This Final Rule

In this final rule, we are adopting 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).

• Requirement to indicate the net quantity of hazardous material per package on the shipping paper if transportation is by aircraft.

• 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 assignments 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.

B. International Standards Not Being Adopted in This Final Rule

This final rule makes 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 adopting 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).

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 significant amendments to the international regulations that we are not adopting in this final rule with a brief explanation of why the amendment was not included:

•
Environmentally hazardous substances.
The UN Recommendations include new defining criteria for environmentally hazardous substances. The UN criteria have not yet been adopted by ICAO and IMO. We will consider these changes 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. On September 21, 2006, PHMSA published an advance notice of proposed rulemaking (71 FR 55156) to consider revisions to the list of hazardous materials that triggers security plan requirements under the HMR. We will consider whether the HMR list should be harmonized with the UN Recommendations list as part of this initiative.

•
Requirements for radioactive materials.
We are not adopting 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 adopting 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 adopting 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 adopting 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 a special permit and by motor vehicle, rail, cargo vessel and cargo aircraft with approval of the Associate Administrator. These issues will be considered in a separate rulemaking proceeding.

•
Marking of Limited Quantity shipments.
The ICAO Technical Instructions include a marking requirement for packages containing a limited quantity of hazardous material. The mark 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.

III. Section-by-Section Review

Part 171

Section 171.7

Section 171.7 lists the standards incorporated by reference into the HMR. We are updating 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. We did not receive comments opposing these incorporations by reference; therefore the standards are updated as follows:

• The ICAO Technical Instructions, 2007-2008 Edition.

• The IMDG Code, Amendment 33-06.

• 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. Comments pertaining to transition periods are discussed below.

Paragraph (b) lists transitional provisions related to revised placarding requirements. In this final rule, we are removing paragraph (b) because the transition period has expired.

Paragraph (d) of this section specifies transitional provisions for previously adopted amendments intended to harmonize the HMR with international standards. We are revising this paragraph to provide specific transitional provisions for certain amendments in this final rule. The effective date of this final rule is January 1, 2007, and the mandatory compliance date is January 1, 2008. We are permitting voluntary compliance as of January 1, 2007, to correspond with the effective implementation dates of the 2007-2008 ICAO Technical Instructions and Amendment 33-06 of the IMDG Code. This authorization allows 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 transitional provision. In this final rule, we are replacing the outdated transitional provision with a new paragraph (e) that permits use for domestic shipments of the shipping description sequences in effect on December 31, 2006, until January 1, 2013. 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 are revising 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, 2014 for transportation by highway and until January 1, 2011 for transportation by rail, vessel or aircraft. See the §§ 172.407, 172.427 and 172.552 preamble discussions for a complete explanation of this issue.

In new paragraph (g), we are allowing 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 containing the hazard class or division for each specific material listed in the HMT. Paragraph (d)(4) addresses entries classed as combustible liquids. In the NPRM, we proposed 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 adoption of the GHS within the UN Recommendations. We did not receive comments opposing this proposal; therefore, it is adopted in this final rule.

The § 172.101 Hazardous Materials Table (HMT)

In this final rule, we are making various amendments to the § 172.101 Hazardous Materials Table (HMT). Readers should review all changes for a complete understanding of the Table amendments. For purposes of the Government Printing Office's typesetting procedures, changes to the HMT appear under three sections of the Table, “remove,” “add” and “revise.” Certain entries in the HMT, such as those with revisions to the proper shipping names, will appear as a “remove” and “add.” We did not receive comments opposing the changes to the HMT proposed in the NPRM. Therefore, in this final rule we are adopting the following amendments to the HMT for the purpose of harmonizing with international standards:

1. We are correcting 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:

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 revising 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.

3. The entry “Aerosols,
non-flammable, (each not exceeding 1 L capacity)
,” UN1950, is revised by adding vessel storage location code “A” in Column (10A). This code was inadvertently removed in a final rule published September 23, 2005 under Docket HM-189Y (70
FR
56084).

4. The entry “Antimony trichloride, solid,” UN1733, PG II, is revised by adding Special Provisions T3 and 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, is 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, is 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, is revised by removing the reference to § 173.153 “Exceptions for Division 6.1 (poisonous materials)” in Column (8A).

7a. The entry “Calcium hypochlorite, hydrated
or
Calcium hypochlorite, hydrated mixtures,” UN2880, PG II, is revised by removing Special Provision 166.

8. In accordance with changes in the Fourteenth revised edition of the UN Recommendations, we are removing the following entries:

—“Carbon dioxide and nitrous oxide mixtures,” UN1015;

—“Carbon dioxide and oxygen mixtures, compressed,” UN1014; and

—“Carbon monoxide and hydrogen mixture, compressed,” UN2600.

9. The entry, “Charges, shaped, flexible, linear,” UN0288, is 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, is 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, is 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, is revised by removing the reference to § 173.153 “Exceptions for Division 6.1 (poisonous materials)” in Column (8A).[?USGPO Galley End:?]

13. The entry “Chlorosilanes, toxic, corrosive, flammable, n.o.s.,” UN3362, PG II, is 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) is revised by adding the Division 6.1 subsidiary hazard labeling requirement.

15. The entry “Compressed gas, n.o.s.,” UN1956, is 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, water-activated,
with burster, expelling charge or propelling charge,
” UN0248, is revised by removing Special Provision 101, which requires the name of the particular substance or article to be specified. In addition, the letter “G” is added to Column (1), requiring the proper shipping name to be supplemented with the technical name of the hazardous material.

17. The entry, “Contrivances, water-activated,
with burster, expelling charge or propelling charge,
” UN0249, is revised by removing Special Provision 101, which requires the name of the particular substance or article to be specified. In addition, the letter “G” is 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, is 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, is revised to read “Crotonaldehyde
or
Crotonaldehyde, stabilized” and to add 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, is corrected to read “Crotonic acid, liquid” and the Identification Number is 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, is 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,” UN3363, is revised by adding quantity limits for transportation by aircraft. The quantity limits are specified in new Special Provision A105.

23. The entry “Ethyltrichlorosilane,” UN1196, PG II, is 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, is revised to read “Formic acid
with more than 85% acid by mass,
” and the Class 3 subsidiary hazard is 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, is added.

26. A new entry, “Formic acid
with not less than 5% but less than 10% acid by mass,
” UN3412, is added.

27. A new entry, “Fuel cell cartridges
containing flammable liquids,
” UN3473, is added.

28. The entry “Hydrazine aqueous solutions,
with more than 37% hydrazine, by mass,
” UN2030, PG I, is 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,” UN3468, is 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, is 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, is 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, is 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, is 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, is 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 addition of Special Provision T9 removes this requirement.

34. For the entry “Hydrogen-difluorides, n.o.s.,” UN1740, PG II and III, the proper shipping name is revised 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, is added.

36. The entry “Hydroquinone, solid,” UN2662, is removed.

52. The entry “Plastic molding compound
in dough, sheet or extruded rope form evolving flammable vapor,
UN3314, PG III, is revised by removing Vessel stowage location A and adding location E in Column (10A), and by removing Vessel stowage provision 85 and adding Vessel stowage provisions 19, 21, 25 and new Vessel stowage provision 144 in Column (10B).

53. The entry “Polymeric beads, expandable,
evolving flammable vapor,
UN2211, PG III, is revised by removing stowage location A and adding location E in Column (10A), and by removing Vessel stowage provision 85 and adding Vessel stowage provisions 19, 21, 25 and new Vessel stowage provision 144 in Column (10B).

54. For the entry “Propionic acid,” UN1848, the proper shipping name is revised to read, “Propionic acid
with not less than 10% and less than 90% acid by mass

61. The entry “Trimethylchloro-silane,” UN1298, PG II, is 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 adding the designation “PP” to indicate that copper chloride is a severe marine pollutant. We are also correcting 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 December 20, 2004 under Docket HM-215G (69
FR
76044) and removal of the entry “1,2-Dichlorobenzene” was overlooked in a final rule published June 21, 2001 under Docket HM-215D (66
FR
33316).

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. We did not receive comments opposing the revisions proposed in the NPRM; therefore, in this final rule for consistency with international standards, we are amending § 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 are revising 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 non-hazardous solids and flammable liquids. In accordance with the UN Recommendations, Special Provision 47 is 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 are excepted from the HMR provided there is no free liquid in the packet or article.

• Special Provision 77 applies to use of the Division 5.1 subsidiary risk label. We are revising this special provision for consistency with the wording in the UN Recommendations. As a result, Special Provision 77 will no longer apply only to “domestic transportation.” Further, we are clarifying that a Division 5.1 label is not required for mixtures containing not more than 23.5% oxygen by volume. Also, the provision is assigned 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 final rule, we are removing the entry for “Carbon dioxide and oxygen mixtures, compressed.”

• Special Provision 146 is amended to authorize the domestic classification of a material as environmentally hazardous if it is designated as such by a foreign competent authority. The provision as currently worded only allows such classification for international shipments. Due to current differences in criteria for the classification of environmentally 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. Although generally the HMR do not authorize materials not meeting the definition of a hazardous material to be transported as regulated materials, due to the low risk posed by these materials, and the fact that the HMR already authorize domestic movement in association with international air and vessel transport, we believe this change will not result in a significant impact other than to lower costs for our stakeholders.

• 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 is 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 are revising Special Provision 166 to remove the authorization for “hydrated” non-friable tablet forms of calcium hypochlorite to be transported as a PG III material.

• A new Special Provision 175 is added to require stabilization for certain substances when transported in concentrations of not more than 99%.

• Special Provision 101 is removed. This special provision required 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 became obsolete.

• A new Special Provision A105 is added to specify the quantity of hazardous materials allowed in equipment or apparatus.

Section 172.202

Shipping Description Sequence

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 in accordance with the ICAO Technical Instructions and the IMDG Code. In the NPRM, we proposed to adopt the current, alternative shipping description sequence as the mandatory basic description of a hazardous material on a shipping paper. We also proposed a two-year transition period to allow offerors adequate time to convert to the new shipping description sequence.

A total of 19 commenters addressed this proposal. Eight commenters [NPCA, AP&C, ATA, GPS, LabCorp, NTTC, UPS, and VHOMA] support the proposal. NPCA notes that many of its members have already implemented this change to simplify internal shipping processes.

Eleven commenters [Adamo; AllChem; Botteri; Eisenhofer; ISSA, J&S; NACD; NATC; RST; and two unidentified commenters] oppose this proposal, suggesting that the change is not necessary, lacks an economic justification, and will have a negative impact on safety. These commenters note that, because the current regulations allow the international sequence as an alternative, the proposed change merely removes the existing sequence with no positive safety rationale. These commenters further assert that the proposed change could result in significant cost impacts to companies that utilize computer systems for the preparation of shipping documents and to track associated packaging and training requirements. According to these commenters, potential costs could include database reorganization, employee training, and related revisions to product labels that also include shipping information. Commenters suggest that costs could also result from confusion on the part of enforcement and inspection personnel that could lengthen inspections and delay shipments. These commenters are also concerned that the proposed revision could have a negative impact on safety because it could result in confusion for emergency response personnel, most of whom are volunteers and receive limited training. Commenters note that confusing emergency response information could expose emergency responders to unnecessary danger.

PHMSA does not believe this proposal is unnecessary or will adversely impact transportation safety. A uniform system for describing and identifying hazardous materials on shipping papers, as proposed in this NPRM, will increase safety by helping to eliminate potential indecision and confusion during emergency situations. For example, when incidents occur during transportation, it is crucial to promptly identify packages of hazardous materials present in a given shipment. Emergency responders at the scene of an incident would use a standard description of hazardous materials on shipping papers to quickly determine that they have accounted for all hazardous materials in both domestically- and internationally-bound packages. In addition, following the release of a hazardous material, it is vital for emergency responders to quickly identify the hazardous materials to facilitate their emergency response decision-making. A standardized shipping description for both domestic and international shipments will aid in this process and will lead to a potential reduction in the loss of life and property.

PHMSA analyzes potential cost impacts of proposed regulations on the regulated community. Our justification regarding this proposal in the Regulatory Evaluation is located under the Docket Management System (
http://dms.dot.gov
). In the Regulatory

Evaluation, we determined that this NPRM, including this specific proposal, should result in cost savings by easing the regulatory compliance burden for shippers and carriers engaged in international commerce, including trans-border shipments within North America. In addition, shippers and carriers will not need to revise shipping papers to address differing domestic and international requirements for shipping descriptions. We acknowledge the proposal to require one basic description of a hazardous material on a shipping paper will necessitate additional training and software revisions. However, to allow for the training of hazmat employees and to ease the minimal burden on entities affected by the adoption of the proposed amendments, we are authorizing an extended transition period. An extended transition period will allow businesses to incorporate this requirement into their training material for both new and current hazardous materials employees, and to upgrade system software over the course of normal computer upgrades and revisions with a minimal economic impact.

The NPRM proposed a two-year transition period to allow shippers sufficient time to convert to the new shipping description sequence. Three commenters [NTTC, ATA, and VOHMA] suggest the proposed transition period is unnecessary and recommend a one-year transition. These commenters state that the industry is able to alter current software systems and deplete pre-printed shipping paper inventory within a relatively short time period. VOHMA asserts lengthy transition periods create confusion and increased training burdens. Six commenters [ATA; GPS; LabCorp; NTTC; UPS; VOHMA] state that the proposed transition period is too short, recommending up to six years to permit shippers to convert to the new sequence. These commenters suggest a longer transition period would allow the new shipping sequence to be incorporated into responder training programs and the next revision of the Emergency Response Guidebook (ERG). The ERG lists hazardous materials in numerical order of ID number and in alphabetical order of material name.

We understand commenters' concerns regarding the length of the transition period for this proposal. However, it is our intention to specify a uniform method to describe a hazardous material on a shipping paper in order to promote the universal recognition of hazardous materials, while allowing sufficient time for affected parties to properly train personnel, reconfigure internal computer systems, and deplete existing stock. We do not believe a time period less than six years would allow businesses to adequately accomplish these objectives. Moreover, a six-year transition period would allow for the incorporation of this requirement into the initial and recurrent training cycle for hazardous materials employees and emergency responders.

Therefore, for the reasons described above, in this final rule, we are adopting the requirement that the shipping description of a hazardous material be indicated on a shipping paper in the following manner: Identification (ID) number listed first, followed by the proper shipping name, hazard class, and packing group. In addition, we are authorizing a six-year transition period to implement this requirement.

Quantity Limitations

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, in the NPRM we proposed 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

As proposed, different size packages containing different quantities of the same hazardous material must be clearly identified. For example:

UN1263, Paint, 3, PG II, 5 fiberboard boxes x 5 L, 6 fiberboard boxes x 10 L

As proposed, where the letter “G” follows the quantity in Column (9A) or (9B), the gross mass rather than the net quantity must be indicated.

A commenter [DGAC] opposes the proposal to require the quantity of a hazardous materials shipment by aircraft to be expressed as a net quantity per package. The commenter questions the safety benefit of adopting the requirement and states that the costs to industry associated with the change, such as computer software upgrades, may be substantial. The commenter did not provide data to support this argument. We disagree that there is no safety benefit in expressing the quantity of hazardous material in terms of “net quantity” for air shipments. Quantity limitations aboard aircraft, as prescribed in § 175.75, are specified in the HMR as net quantities; thus, an indication of the net quantity per package on shipping papers facilitates load planning and compliance. We do not believe the cost of indicating net quantity rather than total quantity, as previously required, is increased substantially. Therefore, in this final rule, we are adopting the amendment as proposed.

In the NPRM, we also proposed 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.

On the proposal to identify the total quantity of each hazardous material in machinery or apparatus, a commenter [UPS] states that the “precision implied in this proposal is unrealistic.” UPS suggests that, absent a precise quantity, a shipper should be permitted to estimate the quantity of hazardous material. We agree and are amending paragraph (a)(6)(iii) accordingly.

Another commenter [Laude] requests we include net quantity provisions for Class 7 materials transported by aircraft. Similar provisions for transportation by other modes are contained in paragraph (a)(5). We agree with the commenter and are amending paragraph (a)(6) accordingly.

The same commenter points out that in proposed paragraph (a)(6)(vi) ID numbers UN2807 and UN3173 do not exist in the HMT; (ID number UN2807 is assigned to “magnetized material” in the ICAO Technical Instructions). We are removing UN2807 and UN3173 in this final rule.

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.

We proposed to amend paragraph (a) by requiring orientation markings on single packagings fitted with vents and on open cryogenic receptacles intended for the transport of refrigerated liquefied gases. We received one comment [AP&C] supporting the proposal and, in this final rule, are adopting the amendment as proposed.

Also, we proposed 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 the color of the arrows to be either black or red on a suitable contrasting background. One commenter [AP&C] supports the proposal requiring the size of the marking to be proportionate with the size of the package. Several commenters [NATC; Botteri; Eisenhofer; Adamo; NACD; J&S; RST; AllChem; UC1; UC2] question the meaning of the phrase “clearly visible” and suggest we specify the size of the marking; either by requiring the marking to be at least equal to the size of the largest package marking or, at a minimum, requiring the marking to be
1/2
inch. We agree with commenters that the phrase “clearly visible” is vague; however, we disagree with specifying the size of the orientation marking. The HMR currently require non-bulk packages containing liquid hazardous materials to be “legibly marked” with the orientation marking. Specifying the size of the orientation marking would be inconsistent with the general marking requirements (proper shipping name and identification number) for non-bulk packagings which do not specify the size of the markings. In this final rule, we are removing the phrase “clearly visible” and requiring the orientation marking to be commensurate with the size of the package.

We also proposed adding a new paragraph (c)(7) to except Class 7 materials in Type A, IP-2, IP-3, Type B(U), or Type B(M) packages from the orientation marking requirement. We received no comments on this proposal and are adopting the amendment as proposed.

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 proposed to revise the ORGANIC PEROXIDE label. The revised label would reflect the fact that organic peroxides are highly flammable and enable transport workers to readily distinguish peroxides from oxidizers. We also proposed to authorize labels meeting the specifications in effect on December 31, 2006, to continue to be displayed until January 1, 2011 (see § 171.14). This would 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.

We received no comments opposing the proposal to revise the ORGANIC PEROXIDE label; therefore, in this final rule we are adopting the revisions as proposed.

Section 172.552

Section 172.552 establishes specific requirements for the ORGANIC PEROXIDE placard. In accordance with the UN Recommendations, in paragraph (b), we proposed to revise the ORGANIC PEROXIDE placard. The revised placard would reflect the fact that organic peroxides are highly flammable and enable transport workers to readily distinguish peroxides from oxidizers. We proposed to authorize placards meeting the specifications in effect on December 31, 2006, to continue to be displayed until January 1, 2011 (see § 171.14).

We received one comment [ATA] supporting the revised placard design; however, ATA disagrees with the length of the proposed transition period. The ATA requests a seven-year transition period until January 1, 2014. The ATA states that trucking companies with large fleets use dual metal flip placards on each side of the trailer. According to the ATA, trailer fleets are generally refurbished every seven years. This would allow companies to replace the ORGANIC PEROXIDE placard at the time of refurbishment. Based on this comment, in this final rule, we are authorizing ORGANIC PEROXIDE placards meeting the specifications in effect on December 31, 2006, to continue to be displayed until January 1, 2014 for transportation by highway and until January 1, 2011 for transportation by rail, vessel or aircraft.

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 fumigated transport vehicle or freight container was ventilated to remove harmful concentrations of fumigant gas. To minimize the possibility of an individual entering a fumigated transport vehicle or freight container prematurely, in the NPRM we proposed to require the FUMIGANT marking to include the date of ventilation. We also proposed to revise the specifications for the FUMIGANT marking to allow either red or black marking on a white background. No commenters opposed these proposals, therefore, we are adopting them without change in this final rule.

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. In the NPRM, we proposed to revise all of these sections to reflect the new upper limit of 60 °C (140 °F) for a PG III flammable liquid. This is consistent with recent changes to the classification of flammable liquids based on the GHS and adoption into the UN Recommendations. PHMSA also proposed to authorize a five-year transition period.

A commenter [DGAC] appreciates the length of the proposed transition period. DGAC urges PHMSA to propose a similar transition period for the criteria in international regulations. Modifications to the international standards are outside the scope of this rulemaking. International shippers should be aware of this disparity and take appropriate action. In this final rule, we are adopting the amendment as proposed.

Section 173.115

The HMR define a Division 2.2 non-flammable 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 proposed 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). We received no comments opposing this proposal; therefore, in this final rule, we are adopting the proposal without change.

Currently, paragraph (k)(5) of this section requires aerosols containing Class 8, PG III materials to be assigned a Class 8 subsidiary hazard. In the NPRM, we proposed 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. We received no comments opposing this proposal; therefore, in this final rule, we are adopting the proposal without change.

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. In the NPRM, we proposed to revise § 173.124 by adding a new paragraph (a)(2)(i)(D)(
3
) 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 self-react and to ensure that in such instances, these substances are appropriately classed for their self-reactive hazard. We received no comments on this proposal; it is adopted without change in this final rule.

Section 173.133

Section 173.133 establishes criteria for assignment of packing groups to poisonous (Division 6.1) materials. We proposed 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 would now be regulated as Division 6.1, Packing Group III; some materials currently regulated as Division 6.1, Packing Group I or II are assigned to a different packing group; and some materials that were previously regulated as Division 6.1, Packing Group III would no longer be subject to regulation under the HMR. PHMSA also proposed a five-year transition period.

The effect of these proposed changes to packing group assignments for Division 6.1 materials is summarized as follows:

Material properties
Current PG assignment
New PG assignment

Oral LD
50
> 200, ≤ 300 (Solid)

Not regulated
III

Oral LD
50
> 300, ≤ 500 (Liquid)

III
Not regulated.

Dermal LD
50
> 40, ≤ 50

II
I

Inhalation toxicity by dusts and mists LC
50
> 0.2, ≤ 0.5

I
II

Inhalation toxicity by dusts and mists LC
50
> 4, ≤ 10

III
Not regulated.

Thirteen commenters [NATC; Botteri; Eisenhofer; Adamo; J&S; RST; AP&C; AllChem; Arkema; UC1; UC2; NACD; DGAC] support adoption of this proposal. Arkema notes that the amended criteria may result in reclassification of certain materials that are listed by name in the HMT. The commenter requests that the HMR be amended to allow the use of currently listed names instead of describing the material under an appropriate generic (n.o.s.) name based on the new toxicity criteria. The commenter also states Arkema, an international company, will review its materials to ensure they are in compliance with the provisions of the 2008 IMDG Code, and will handle air shipments on a case-by-case basis. PHMSA does not intend to provide such an allowance in the HMR; we believe such a provision could be confusing and would be inconsistent with the international regulations. However, we invite submission of data supporting reclassification of certain materials resulting from the revised criteria for toxic materials. Such data could be used to effect change in the listing of a material within the HMR and the UN Model Regulations.

A commenter [DGAC] appreciates the length of the proposed transition period. DGAC urges PHMSA to propose a similar transition period for the criteria in international regulations. Changes to the international standards are outside the scope of this rulemaking. International shippers should be aware of this disparity and take appropriate action.

Finally, ten commenters [NATC; Botteri; Eisenhofer; Adamo; J&S; RST; AllChem; UC1; UC2; NACD] request a five-year transition period and a grandfather clause to allow packages filled prior to a specific date to remain marked without modification for domestic transportation. In the NPRM, we proposed a five-year transition period and in this final rule, we are adopting the amendment as proposed (see § 171.14). We disagree with the request to allow packages filled prior to a specific date to remain marked without modification for domestic transportation. We believe that a five-year transition provides adequate time to transition to the new classification criteria and to ensure that packages marked based on regulations in effect on December 31, 2006, are out of the transportation stream. Therefore, we are not adopting a grandfather clause.

Sections 173.134 and 173.197

Consistent with the proposals in the NPRM, in this final rule, these sections are revised by replacing the wording “Regulated medical waste” with the wording “Regulated medical waste or clinical waste or (bio) medical waste.” No commenters addressed this issue.

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 the Class 8 definition should apply equally to liquids and to solids offered for transportation or transported in a liquid state. In the NPRM, we proposed to revise the definition of a “corrosive

material” to include a solid material that is offered for transportation or transported as a liquid and has a severe corrosion rate on steel or aluminum. A commenter [Degussa] requests that we align the definition with the UN Recommendations. We agree and are modifying the definition of “corrosive material” to include the phrase “solids that may become liquid during transportation.” Also, we are removing 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 December 20, 2004 under Docket HM-215G (69
FR
76155), 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 the NPRM, we proposed 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. No commenters addressed this proposal; it is adopted without change in this final rule.

Section 173.159

Section 173.159 establishes transportation requirements for wet electric storage batteries. For consistency with the ICAO Technical Instructions, in the NPRM we proposed 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). No commenters addressed this proposal; therefore, we are adopting it without change in this final rule.

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. In the NPRM, we proposed to revise paragraph (d)(1) to expand the exception to include air bag modules and seat-belt pretensioners installed in other means of conveyances, such as boats and aircraft, or their components. We received no comments on this proposal; therefore, we are adopting it without change in this final rule.

Section 173.187

Section 173.187 establishes transportation requirements for pyrophoric solids, metals, or alloys, not otherwise specified (n.o.s.). In the NPRM, we proposed 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. We received no comments on this proposal; it is adopted without change in this final rule.

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 the NPRM, we proposed to require bags or other non-rigid packages containing asbestos to be transported in rigid outer packages or closed freight containers. No commenters addressed this proposal; therefore, it is adopted without change in this final rule.

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. In the NPRM, we proposed 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, consistent with the ICAO Technical Instructions, we proposed 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). We received no comments on these proposals; therefore, we are adopting them without change in this final rule.

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. In the NPRM, we proposed to revise paragraph (d) accordingly. No commenters addressed this proposal, and it is adopted without change in this final rule.

A commenter [Laude] requests we remove the phrase “equipment” in this section. The phrase “equipment” is not part of the proper shipping name “Dangerous Goods in Machinery
or
Dangerous Goods in Apparatus” in the HMT. Therefore, we are editorially revising § 173.222 to remove the phrase “equipment” in the heading and regulatory text.

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 the NPRM, we proposed to add a new entry to “Acetone-pyrogallol copolymer 2-diazo-1-naphthol-5-sulphonate” to the Self-Reactive Materials Table. We received no comments on this proposal, and are adopting it without change in this final rule.

Section 173.230

In the NPRM, we proposed to add a new packaging section (§ 173.230) for the transportation of “Fuel cell cartridges
containing flammable liquids
, UN3473,” including methanol or methanol/water solutions. For consistency with the ICAO Technical Instructions, we proposed 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.

A commenter [HMT] suggests we add a special provision to the entry “Fuel cell cartridges containing flammable liquids” in the HMT that would allow fuel cell cartridges to be considered the inner packaging of a combination packaging so that shippers can take advantage of the limited quantity provisions for flammable liquids in § 173.150. We do not believe that such a clarification is necessary. A fuel cell cartridge, shipped under the provisions

of § 173.150 as a limited quantity, may be considered the inner packaging provided all applicable requirements are met. The commenter also suggests we change the one liter net capacity limit to allow up to one liter volume of the flammable liquid itself. We do not agree. The net capacity of a fuel cell cartridge should be the capacity of the fuel cell cartridge containing the flammable liquid. This is consistent with the requirements for other flammable liquids shipped as a limited quantity in inner packagings or articles. Finally, the commenter recommends we authorize any rigid outer packaging conforming to the PG II performance level. We agree and are amending the requirements in paragraph (a)(2) accordingly.

Section 173.301

On August 29, 2006, the
Federal Register
published a final rule under Docket HM-220F (71
FR
51122)) establishing additional requalification requirements for cylinders manufactured of aluminum alloy 6351-T6. In § 173.301, we moved a sentence prohibiting the use of DOT 3AL cylinders manufactured of aluminum alloy 6351-T6 for transporting pyrophoric gases from paragraph (d) to a new paragraph (o). We revised the remaining requirement in paragraph (d). However, we inadvertently omitted a sentence prohibiting the use of aluminum alloy 6351-T6 for the manufacture of UN cylinders recently added in paragraph (d) under a final rule published June 12, 2006 under Docket HM-220E (71
FR
33858). In this final rule, we are correcting § 173.301(o) by reinserting the language prohibiting the use of UN cylinders manufactured of aluminum alloy 6351-T6.

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 the NPRM, we proposed 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 Subpart B of Part 173. 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 exceptions in the UN Recommendations and ICAO Technical Instructions include an exception from shipping paper, package marking, and labeling requirements, a carrier might not be aware of the potential risks associated with higher pressure aerosols and small gas receptacles. In addition, to avoid confusion and further clarify the intent of this exception, in the NPRM we proposed 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. We received no comments on this proposal; it is adopted in this final rule.

Part 175

Section 175.10

Currently, safety matches or lighters carried on board an aircraft and intended for use by a passenger or crew member are excepted from the HMR. Consistent with the ICAO Technical Instructions, in the NPRM we proposed 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. We received no comments on this issue; therefore, it is adopted without change in this final rule.

Section 175.78

Section 175.78 establishes requirements for stowing hazardous materials on an airplane. In the NPRM, we proposed to 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. We received no comments on this issue; therefore, it is adopted without change in this final rule.

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. Consistent with recent changes to the classification of flammable liquids based on the GHS and adopted into the UN Recommendations and discussed elsewhere in this preamble, in the NPRM we proposed to revise paragraph (f)(2) to specify the new upper limit for a PG III flammable liquid to be 60 °C (140 °F). We received no comments on this issue; therefore, it is adopted without change in this final rule.

Section 176.83

Section 176.83 establishes segregation requirements for hazardous materials transported by vessel. In the NPRM, we proposed to revise paragraph (a)(4) to identify materials of different hazard classes that do not react dangerously with each other and, therefore, do not need to be segregated. No commenters addressed this proposal; it is adopted without change in this final rule.

Section 176.84

Section 176.84 contains additional stowage and segregation requirements for hazardous materials on cargo and passenger vessels. Consistent with the 2004 Edition of the IMDG Code, incorporating Amendment 33-06, in the paragraph (b) Table of provisions, in the NPRM we proposed to add new Code “144” 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. New Code “144” specifies these materials must be mechanically ventilated in accordance with SOLAS Chapter II-2/Regulation 19 for flammable liquids with a flashpoint below 23 °C (73 °F) when stowed under deck. No comments addressed this issue; it is adopted without change in this final rule.

Also, in the NPRM, we proposed 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 one another and the quantities per package do not exceed 30 L (7.8 gallons) for liquids and 30 kg (66 lbs.) for solids. We also proposed to revise Codes “26,” “27,” “52,” and “53” to add the new Note “2.”

One commenter [VOHMA] supports the proposal to add a new Note “2,” but suggests the following provision be added: “The transport document must include the statement required by § 172.203(i)(5) and a copy of the test report that verifies that the substances do not react dangerously with each other shall be provided if requested by the competent authority.” The commenter also recommends an additional shipping paper requirement under § 172.203 to indicate the utilization of this provision. The commenter bases its request on a need for consistency with the IMDG Code, and the need for verification to the carrier that the substances have been

tested and do not react dangerously with each other.

We acknowledge the commenter's recommendation that new Note “2” may require an accompanying statement on a transport document, such as a shipping paper, in order to adequately notify carriers of the use of this provision. We also acknowledge the commenter's suggestion that supporting documentation, such as a test report, should accompany shipments of these hazardous materials. Because these additional requirements were not proposed in the NPRM, they are beyond the scope of this rulemaking. However, we agree that carriers may need some notification of the use of this provision and will consider the issue in a future rulemaking.

In this final rule, we are adopting the proposal to add new Note “2” to the Segregation Table, and to revise Codes “26,” “27,” “52,” and “53” by adding the new Note “2,” as proposed in the NPRM. In addition, we are also adopting the proposal to add Code “144” 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. Finally, in paragraph (b), we are revising Provisions “22,” “23,” and “109” to reflect the new upper flammability limit for flammable liquids. Also see §§ 173.35, 173.120, 173.121 and Appendix H to Part 173 preamble text.

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 to be 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 Fourth revised edition of the UN Manual of Tests and Criteria 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 Manual of Tests and Criteria.

Consistent with the UN Recommendations, in the NPRM we proposed 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. The NPRM proposed an effective for the new requirement of January 1, 2008, and further proposed that UN portable tanks impact-tested prior to January 1, 2008, based on the criteria in effect on October 1, 2005, need not be retested. We received no comments on this proposal; we are adopting it without change in this final rule.

Section 178.602

Section 178.602 establishes requirements for the preparation of packagings for testing to ensure 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. In the NPRM, we proposed to revise paragraph (b) to clarify that the preparation of bags for the drop and stacking tests only applies to bags containing solids. No commenters addressed this proposal; it is adopted without change in this final rule.

Section 178.810

Section 178.810 establishes requirements for performing the drop test for IBCs. In the NPRM, we proposed 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 proposed to require fiberboard and wooden IBCs to be filled with a solid material to not less than 95% of their maximum capacity. Also, we proposed to add a new paragraph (b)(3) to require filling flexible IBCs to the maximum permissible gross mass and even distribution of the contents. No commenters addressed these proposals; they are adopted without change in this final rule.

Part 180

Section 180.213

On August 29, 2006 the
Federal Register
published a final rule under Docket HM-220F (71
FR
51122) establishing additional requalification requirements for cylinders manufactured of aluminum alloy 6351-T6. In the amendatory language, we inadvertently revised paragraph (d) rather than the paragraph (d) introductory text. In this final rule, we are revising paragraph (d) to correct this error.

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. In the NPRM, we proposed 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 proposals incorporate clarifications adopted in the Fourteenth revised edition of the UN Recommendations. We received no comments on these proposals and are adopting them without change in this final rule.

IV. 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 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.

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. Moreover, we are maintaining a number of current exceptions for domestic transportation that should minimize the compliance burden on the regulated community.

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 rule incorporates 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.

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. The final rule is not considered a significant rule under the Regulatory Policies and Procedures of the Department of Transportation [44 FR 11034]. This final rule applies to offerors and carriers of hazardous materials, such as chemical manufacturers, chemical users and suppliers, packaging manufacturers, distributors, battery manufacturers, and radiopharmaceutical companies. Benefits resulting from 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 U.S. manufacturers of hazardous materials.

The majority of amendments in this final rule 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 are authorizing a delayed effective date and a one-year transition period for the majority of amendments in this final rule; we are authorizing extended transition periods for certain amendments. The transition periods allow for training of employees and ease any burden on entities affected by the amendments. The total net increase in costs to businesses in implementing the final rule is considered to be minimal. The costs are the result of reprogramming shipping paper computer programs, replacement of pre-printed forms for firms that do not use automated systems, and changes to package markings and labels. Initial start-up and inventory costs result from these changes; however, the costs will be offset by greater long-term 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 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 impose 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 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, 2007. If the changes in this final 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 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 29, 2007.

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 and does not impose substantial direct compliance costs, 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, and battery manufacturers. As discussed above, under
Executive Order 12866
, the majority of amendments in this final rule 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 the requirements in this final rule will not 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 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 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 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 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. 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 conclude that there are no significant environmental impacts associated with this final rule. 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.).
