Unfunded Mandates Reform Act I. Environmental Assessment J. Privacy Act 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. [[Page 51895]] 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 [[Page 51896]] 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 Sec. 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 Sec. Sec. 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 Sec. Sec. 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 [deg]C (141 [deg]F) to 60 [deg]C (140 [deg]F). This is consistent with recent changes to the classification of flammable liquids based on the GHS and adoption into the UN Recommendations. The Sec. 172.101 Hazardous Materials Table (HMT): In the Sec. 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. UN0351............................ Articles, explosive, n.o.s. UN0352............................ Articles, explosive, n.o.s. UN0353............................ Articles, explosive, n.o.s. UN0354............................

Substances, explosive, very insensitive, n.o.s. or Substances, EVI, 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. UN2671............................ Aminopyridines (o-; m-; p-). UN1005............................ Ammonia, anhydrous. UN3318............................ Ammonia solution, relative density less than 0.880 at 15 degrees C in water, with more than 50 percent ammonia. UN2672............................

The entry ``Aerosols, non-flammable, (each not exceeding 1 L capacity),'' UN1950, would be revised by adding vessel storage location code ``A'' in Column (10A). This code was inadvertently removed in a final rule published under Docket HM-189Y (70 FR 56084; September 23, 2005). 4. The entry ``Antimony trichloride, solid,'' UN1733, PG II, would be 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, 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 Sec. 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 Sec. 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 Sec. 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 Sec. 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 Sec. 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 Sec. 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, water-activated, 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, water-activated, 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 Sec. 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 Sec. 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 Sec. Sec. 172.202 and 172.402, respectively. 28a. The entry ``Hydrogen in a metal hydride storage system,'' [[Page 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 Sec. 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 Sec. 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, water- reactive,'' 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 Sec. 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 Sec. 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 Sec. 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 Sec. 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 Sec. 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: [[Page 51900]] --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 Sec. 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 Sec. 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 Sec. 178.275 of the HMR, where the test pressure is 1.5 times the maximum allowable working pressure. 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 Sec. 173.150 ``Exceptions for Class 3 (flammable) and combustible liquids'' in Column (8A). Also, see Sec. 172.102 for additional HMT amendments. Appendix B to Sec. 172.101 Appendix B to Sec. 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 Sec. 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 non-hazardous 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. [[Page 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 Sec. 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 Sec. 171.14). Adoption of the redesigned label will eliminate the current requirement in Sec. 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 Sec. 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. [[Page 51902]] 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); Sec. 173.120 establishes classification criteria for flammable liquid (Class 3) materials; Sec. 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 [deg]C (141 [deg]F) to 60 [deg]C (140 [deg]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 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 [deg]C (68 [deg]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 Sec. 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 self-react and to ensure that in such instances, these substances are appropriately classed for their self-reactive 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: ------------------------------------------------------------------------ Current PG Proposed PG Material properties assignment assignment ------------------------------------------------------------------------ Oral LD50 > 200, 300, 40, 0.2, 4, http://dms.dot.gov .

The revisions and additions read as follows: Sec. 172.102 Special provisions. * * * * * (c) * * * (1) * * * Code/Special Provisions * * * * * 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 Sec. 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 Sec. 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 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. 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 Sec. 171.7 of this subchapter), and may not be classified and transported unless approved by the Associate Administrator. * * * * * 166 When transported in non-friable tablet form, calcium hypochlorite, dry, may be transported as a Packing Group III material. * * * * * 175 This substance must be stabilized when in concentrations of not more than 99%. (2) * * * Code/Special Provisions * * * * * A105 The total net quantity of 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 Sec. 172.202, paragraphs (a) and (b) are revised to read as follows: Sec. 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 Sec. 172.101 table; (2) The proper shipping name prescribed for the material in Column (2) of the Sec. 172.101 table; (3) The hazard class or division number prescribed for the material, as shown in Column (3) of the Sec. 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 numerals, as designated for the hazardous material in Column (5) of the Sec. 172.101 table. Class 1 (explosives) materials, self-reactive substances, organic peroxides and entries that are not assigned a packing group are excepted from this requirement. The packing group may be preceded by the letters ``PG'' (for example, ``PG II''); and (5) Except for transportation by aircraft, the total quantity of hazardous materials covered by the description must be indicated (by mass or volume, or by activity for Class 7 materials) and must include an indication of the applicable unit of measurement. For example, ``200 kg'' or ``50 L.'' The following provisions also apply: [[Page 51923]] (i) For Class 1 materials, the quantity must be the net explosive mass. For an explosive that is an article, such as Cartridges, small arms, the net explosive mass may be expressed in terms of the net mass of either the article or the explosive materials contained in the article. (ii) For hazardous materials in salvage packaging, an estimate of the total quantity is acceptable. (iii) The following are excepted from the requirements of paragraph (a)(5) of this section: (A) Bulk packages, provided some indication of the total quantity is shown, for example, ``1 cargo tank'' or ``2 IBCs.'' (B) Cylinders, provided some indication of the total quantity is shown, for example, ``10 cylinders.'' (C) Packages containing only residue. (6) For transportation by aircraft, the total net mass per package must be shown unless a gross mass is indicated in Columns (9A) or (9B) of the Sec. 172.101 table in which case the total gross mass per package must be shown. The following provisions also apply: (i) For empty, uncleaned packaging, only the number and type of packaging must be shown; (ii) For chemical kits and first aid kits, the total net mass of hazardous materials must be shown. Where the kits contain solids and/or liquids, the net mass of liquids within the kits is to be calculated on a 1 to 1 basis, i.e., 1 L equals 1 kg; (iii) 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; (iv) For dangerous goods transported in a salvage packaging, an estimate of the quantity of dangerous goods per package must be shown; (v) For cylinders, total quantity may be indicated by the number of cylinders, for example, ``10 cylinders;'' (vi) For items where ``No Limit'' is shown in Column (9A) or (9B) of the Sec. 172.101 table, 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. (7) The number and type of packages must be indicated. The type of packages must be indicated by description of the package (for example, ``12 drums''). Indication of the packaging specification number (``1H1'') may be included in the description of the package (for example, ``12 1H1 drums'' or ``12 drums (UN 1A1)''). Abbreviations may be used for indicating packaging types (for example, ``cyl.'' for ``cylinder'') provided the abbreviations are commonly accepted and recognizable. (b) Except as provided in this subpart, the basic description specified in paragraphs (a)(1), (2), (3) and (4) of this section must be shown in sequence with no additional information interspersed.
