AGENCY:

Research and Special Programs Administration (RSPA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

RPSA is proposing to amend the Hazardous Materials Regulations (HMR) to maintain alignment with international standards by incorporating various amendments, including changes to proper shipping names, hazard classes, packing groups, special provisions, packaging authorizations, air transport quantity limitations and vessel stowage requirements. Because of recent changes to the International Maritime Dangerous Goods Code (IMDG Code), the International Civil Aviation Organization's Technical Instructions for the Safe Transport of Dangerous Goods by Air (ICAO Technical Instructions), and the United Nations Recommendations on the Transport of Dangerous Goods (UN Recommendations), these revisions are necessary to facilitate the transport of hazardous materials in international commerce.

SUPPLEMENTARY INFORMATION:

I. Background

On December 21, 1990, RSPA (“we”) published a final rule (Docket HM-181; 55 FR 52402) based on the United Nations Recommendations on the Transport of Dangerous Goods (UN Recommendations), which comprehensively revised the Hazardous Materials Regulations (HMR), 49 CFR Parts 171 to 180, for harmonization with international standards. Since publication of the 1990 final rule, we have issued four additional international harmonization final rules, (Dockets HM-215A, 59 FR 67390; HM-215B, 62 FR 24690; HM-215C, 64 FR 10742; and HM-215D, 66 FR 33316). 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 International Maritime Dangerous Goods Code (IMDG Code) and the International Civil Aviation Organization's Technical Instructions (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. These recommendations are amended and updated biennially by the UN Committee of Experts. They serve as the basis for National, regional, and international modal regulations; specifically, the IMDG Code issued by the International Maritime Organization (IMO), and the ICAO Technical Instructions issued by the ICAO Dangerous Goods Panel. In 49 CFR 171.12, the HMR authorize domestic transportation of hazardous materials shipments prepared in accordance with the IMDG Code if all or part of the transportation is by vessel, subject to certain conditions and limitations. In § 171.11, subject to certain conditions and limitations, the HMR authorizes the offering, acceptance and transport of hazardous materials by aircraft, and by motor vehicle either before or after being transported by aircraft, provided the shipment is in accordance with the ICAO Technical Instructions.

The continually increasing amount of hazardous materials transported in international commerce warrants the harmonization of domestic and international requirements to the greatest extent possible. Harmonization serves to facilitate international transportation and at the same time ensures the safety of people, property and the environment. While the intent of the harmonization rulemakings is to align the HMR with international standards, we review and consider each amendment on its own merit. Each amendment is considered on the basis of the overall impact on transportation safety and the economic implications associated with its adoption into the HMR. Our goal is to harmonize without sacrificing the current HMR level of safety and without imposing undue burdens on the regulated public. In our efforts to continue to align the HMR with international requirements, this notice of proposed rulemaking (NPRM) proposes changes to the HMR based on the twelfth revised edition of the UN Recommendations, Amendment 31 to the IMDG Code, and the 2003-2004 ICAO Technical Instructions, which become effective January 1, 2003. Petitions for rulemaking concerning harmonization with international standards and the facilitation of international transportation are also addressed in this NPRM and serve as the basis of certain proposed amendments. Other proposed amendments are based on feedback from the regulated industry, other DOT modal administrations and our initiative. Also included are various proposed editorial clarifications. Unless otherwise stated, the proposed revisions are for harmonization with international standards.

II. Overview of Changes in this NPRM

Proposed amendments to the HMR in this NPRM include, but are not limited to the following:

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

—Amendments to the List of Marine Pollutants.

—Revisions and additions of special provisions. Included is the addition of a special provision for assignment to aerosol entries setting forth the criteria for classifying aerosols.

—Addition of a requirement to enter the subsidiary hazard class or subsidiary division number on shipping papers.

—Addition of a requirement to indicate types of packagings on shipping papers.

—Addition of an alternative basic description sequence on shipping papers.

—Revision of marking requirements for limited quantities.

—Addition of an air eligibility marking requirement.

—Revision of requirements in § 173.27 for packagings intended for transportation by aircraft, including revision of requirements for use of absorbent material for such packagings.

—Revision of classification of air bag modules, air bag inflators and seat-belt pretensioners from Division 2.2 to Class 9.

—Revision of the non-liquefied and liquefied compressed gases descriptions, and the addition of high pressure and low pressure liquefied gases categories.

—Revisions and additions to the Self-Reactive Materials Table.

—Revisions and additions to the Organic Peroxide Table.

—Revision of the net weight restrictions for explosives in freight containers exceeding 20 feet (6 m) in length.

III. Summary of Regulatory Changes by Section

Part 171

Section 171.7. We are proposing to update the incorporation by reference materials for the ICAO Technical Instructions, the IMDG Code and the UN Recommendations. The updated editions of these standards become effective January 1, 2003. Additionally, the International Maritime Organization (IMO) recommends authorizing a one-year transition period, with a delayed compliance date of January 1, 2004, for the use of the updated edition (Amendment 31) of the IMDG Code. We are also proposing to authorize use of either Amendment 30 or Amendment 31 of the IMDG Code until January 1, 2004.

The standards would be updated as follows:

—The ICAO Technical Instructions, 2003-2004 edition.

—The IMDG Code, Amendment 31.

—The UN Recommendations, twelfth edition.

We are also proposing to add an IMO standard titled “International Convention for the Safety of Life at Sea,” 1974, as amended, Chapter II-2/Regulation 19, for incorporation into proposed § 176.63 to address hatchless container ship requirements.

Because the updated editions of the international standards become effective January 1, 2003, we are proposing a 30-day comment period for these proposed amendments only. Consistent with our previous harmonization (HM-215 docket numbers) rulemakings, our intent is to publish a separate final rule authorizing the use of these standards by January 1, 2003. This action will authorize compliance with the updated standards when they become effective, and is necessary to prevent disruption of hazardous materials shipments that are being transported internationally.

Section 171.8. In the definition for “Large packaging,” we are proposing to add the words “Chapter 6.6” to let readers know the location in the UN Recommendations for the construction, testing and marking of such packagings.

Section 171.11. We are proposing to revise paragraphs (c), (d)(5) and (d)(17) to address certain limitations for the use of the ICAO Technical Instructions.

In paragraph (c), for hazardous materials being transported in accordance with the ICAO Technical Instructions, the restrictions for the use of the Instructions would be revised to include hazardous materials that are forbidden by passenger and cargo aircraft, as designated in Columns (9A) and (9B) of the § 172.101 HMT. Currently, the paragraph restricts materials that are forbidden according to § 173.21 and Column (3) of the HMT.

In paragraph (d)(5), we are proposing to remove the wording “except for Division 2.2” regarding shipping paper requirements for air bag inflators, air bag modules and seat-belt pretensioners. This proposal is consistent with the proposed removal of the Division 2.2 air bag inflator, air bag module and seat-belt pretensioner entry in the HMT (see § 172.101).

Paragraph (d)(17) would be revised to clarify a current requirement that in addition to organic peroxides, self-reactive substances not specifically identified by name in § 173.224(b) also must be approved by the Associate Administrator in accordance with the requirements in § 173.124(a)(2)(iii).

Section 171.12. We are proposing to revise paragraphs (b)(3), (b)(5), (b)(19), and (b)(20).

In paragraph (b)(3), we are proposing to remove certain viscous flammable liquids as an example of a material designated as a hazardous material subject to the HMR, but not subject to the IMDG Code. The IMO removed the exception in Amendment 31 to the IMDG Code.

In paragraph (b)(5), we are proposing to make an editorial revision by removing a redundant and confusing phrase.

In paragraph (b)(19), we are proposing to remove the wording “except for Division 2.2” regarding shipping paper requirements for air bag inflators, air bag modules and seat-belt pretensioners. This proposal is consistent with the proposed removal of the Division 2.2 air bag inflator, air bag module and seat-belt pretensioner entry in the HMT (see § 172.101).

In paragraph (b)(20), we are proposing to clarify a current requirement that in addition to organic peroxides, self-reactive substances not specifically identified by name in § 173.224(b) must also be approved by the Associate Administrator in accordance with the requirements in § 173.124(a)(2)(iii).

For the readers' information, recently adopted amendments to the International Convention for the Safety of Life at Sea (SOLAS), 1974, as amended, will change the status of the use of the IMDG Code, effective January 1, 2004, from recommended to mandatory for international transportation by vessel. This issue will be addressed under a separate rulemaking.

Section 171.12a. We are proposing to revise paragraph (b)(18) by clarifying a current requirement that in addition to organic peroxides, self-reactive substances not specifically identified by name in § 173.224(b) also must be approved by the Associate Administrator in accordance with the requirements in § 173.124(a)(2)(iii).

Section 171.14. We are proposing to revise paragraphs (d), (d)(1), (d)(2), (d)(4), and (d)(5) and add paragraph (d)(6). Paragraphs (d) and (d)(1) would be revised to authorize a delayed implementation date for the proposed amendments in this NPRM. We are proposing an effective date of October 1, 2003, and a voluntary compliance date of January 1, 2003 to correspond with the effective implementation dates of the 2003-2004 ICAO Technical Instructions and Amendment 31 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, 2003. We are proposing to authorize a delayed compliance date of October 1, 2004, which is comparable to the transition provisions provided in the final rule published under Docket HM-215D. The delayed mandatory compliance date would offer sufficient time to implement the new requirements.

Paragraph (d)(2) would be revised to authorize certain intermixing of old and new requirements.

Paragraph (d)(4) would be revised to include DOT Specification 51 portable tanks in the provision to allow, until January 1, 2010, conformance with the T Codes (Special Provisions) in effect on September 30, 2001.

Paragraph (d)(5) would be revised by extending the October 1, 2005 compliance date allowing proper shipping names that included the word “inhibited” prior to the June 21, 2001 final rule, HM-215D, to continue to be shown on packagings in place of the word “stabilized” until October 1, 2007. Additionally, the October 1, 2007 date would also apply to the proper shipping names in this NPRM that are proposed to be revised by removing the word “compressed” (see § 172.101, HMT).

Paragraph (d)(6) would be added to authorize, until October 1, 2005, the marking of certain other proper shipping names on packagings. The proper shipping names would be those that are proposed to be revised to include the position identifiers of the substituents, such as 2-Ethylbutyl acetate (see § 172.101, HMT).

Part 172

Section 172.101. In the regulatory text preceding the Hazardous Materials Table, we are proposing the following changes:

Paragraph (c)(15) would be revised by removing the words “of inorganic substances.” Currently, unless a hydrate is specifically listed in the HMT, only hydrates of inorganic substances may be identified using the proper shipping name for the equivalent anhydrous substance, provided the hydrates meet the same hazard class, division, subsidiary risk(s) and packaging group. With the removal of the phrase “of inorganic substances,” paragraph (c)(15) would apply to all hydrates.

§ 172.101 The Hazardous Materials Table (HMT). We are proposing to make various amendments to the HMT. 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.” Proposed amendments to the HMT for the purpose of harmonizing with international standards, unless otherwise stated, include, but are not limited to the following:

—“Accumulators, pressurized, pneumatic or hydraulic (containing non-flammable gas), see Articles, pressurized, pneumatic or hydraulic (containing non-flammable gas)” would be added as a “see” entry into the HMT to aid the reader in locating the updated entry. This proposed action is based on feedback we received from users of the HMR after we removed the domestic entry (“Accumulators, pressurized, pneumatic,” UN1956), as well as certain other domestic entries from the HMT in a final rule, HM-215D (66 FR 33316), published June 21, 2001. The entries were removed because we determined that they were no longer necessary considering the HMT already includes equally appropriate international entries. (Also see § 173.306(f) for a related editorial revision.)

—“Air bag inflators, compressed gas or Air bag modules, compressed gas or Seat-belt pretensioners, compressed gas,” Division 2.2, UN3353 would be removed. All air bag inflators, air bag modules and seat-belt pretensioners currently classified as Division 2.2 would be reclassified as Class 9. A provision to allow this reclassification without further testing is also being proposed for incorporation into the HMR (see § 173.166). In line with the proposed removal of this entry, Special Provision 133 would also be removed. We are aware that removal of the UN3353 entry will require repackaging, remarking and relabeling of all compressed gas air bag assemblies. We believe that the delayed mandatory compliance date of October 1, 2004 and the transitional provisions proposed in § 171.14(d)(2), authorizing certain intermixing of old and new requirements, will offer sufficient time and flexibility to implement the new requirements and reduce the costs of meeting this requirement.

—“Air bag inflators, pyrotechnic or Air bag modules, pyrotechnic or Seat-belt pretensioner, pyrotechnic” UN0503, Division 1.4G, would be amended by adding an “I” in Column (1), removing the word “pyrotechnic” from the proper shipping names in Column (2), revising Columns (8A) and (8C) to read “None,” revising Column (8B) to read “§ 173.62” (also see § 173.62), adding proposed Special Provision 161 (see § 172.102), and revising the vessel stowage columns (10A) and (10B). We are proposing to add the “I” in Column (1) because we do not agree that an air bag that meets the criteria for a Division 1.4G explosive should be transported under an air bag description for domestic transportation. We believe that a more appropriate name is “Articles, pyrotechnic for technical purposes,” UN0431. We are not aware of any air bags that have been shown through testing to meet a Division 1.4G classification for transport in the United States.

—“Air bag inflators, pyrotechnic or Air bag modules, pyrotechnic or Seat-belt pretensioner, pyrotechnic,” UN3268, Class 9, would be amended by removing the optional word “pyrotechnic” and adding proposed Special Provision 160 (see § 172.102).

—“Ammonium nitrate, with not more than 0.2 percent combustible material, including any organic substance, calculated as carbon to the exclusion of any other added substance,” UN1942 would be amended by editorially correcting the italicized portion of the proper shipping name by adding the word “total” after “0.2 %.”

—“Ammonium nitrate based fertilizers,” UN2071, and “Ammonium nitrate based fertilizers,” UN2067 would be amended by removing the italicized portion of the proper shipping names, adding proposed new Special Provision 150 to the UN2067 entry, and revising Special Provision 132 which applies to the UN2071 entry (see § 172.102 for Special Provision amendments).

—“Ammonium nitrate fertilizers,” NA2072 and “Ammonium nitrate mixed fertilizers,” NA2069 would be removed. We believe that the international entry “Ammonium nitrate fertilizers,” UN2067 can be used in place of the domestic entries which do not provide any additional exceptions.

—A new entry, “Ammonium nitrate emulsion or Ammonium nitrate suspension or Ammonium nitrate gel, intermediate for blasting explosives,” UN3375 (also see § 172.102, Special Provisions 52 and 147) would be added.

—For the entry “Calcium hypochlorite, hydrated or Calcium hypochlorite, hydrated mixtures, with not less than 5.5 percent but not more than 10 percent water,” UN2880, the wording “not more than 10 percent water” would be revised to read “not more than 16 percent water.”

—Four proper shipping names would be revised by adding the position identifiers of the substituents. The proper shipping names are “Diethylaminopropylamine,” position identifier “3”; “Dimethylcyclohexylamine,” position identifiers “N,N”; “Ethylbutyl acetate,” position identifier “2”; “Propyl chloride” which would be replaced by “1-Chloropropane,” and “Tetrachloroethane,” position identifiers “1,1,2,2,”. Also, see § 171.14(d)(6) for the proposed continued use provision of these proper shipping names.

—The entry “Hydrazine hydrate or Hydrazine aqueous solutions, with not less than 37 percent but not more than 64 percent hydrazine, by mass,” UN2030 and “Hydrazine, anhydrous or Hydrazine aqueous solutions with more than 64 percent hydrazine, by mass,” UN2029 would be removed and “Hydrazine aqueous solution, with more than 37% hydrazine, by mass,” UN2030 and “Hydrazine, anhydrous,” UN2029 would be added.

—Eleven entries would be revised by removing the qualifying word “compressed.” This action is consistent with the revisions to proper shipping names for compressed and liquefied gases that were incorporated into the twelfth edition of the UN Recommendations and which we are proposing to adopt into the HMR (see § 173.115 for additional discussion). The eleven entries are “Boron trifluoride, compressed,” UN1008; “Carbonyl fluoride, compressed,” UN2417; “Diborane, compressed,” UN1911; “Ethylene, compressed,” UN1962; “Hexafluoroethane, compressed or Refrigerant gas R 116,” UN2193; “Nitrogen trifluoride, compressed,” UN2451; “Phosphorus pentafluoride, compressed,” UN2198; “Silane, compressed,” UN2203; “Silicon tetrafluoride, compressed,” UN1859; “Tetrafluoromethane, compressed or Refrigerant gas R 14,” UN1982; and “Xenon, compressed,” UN2036. Also, see § 171.14(d)(6) for the proposed continued use provision of these proper shipping names.

—For the proper shipping name “Lighters or Lighter refills cigarettes, containing flammable gas,” UN1057, the word “cigarettes” would be removed.

—The proper shipping name “Lithium hydroxide, monohydrate or Lithium hydroxide, solid,” UN2680 would be revised to read “Lithium hydroxide.”

—For the entry “Medicine, liquid, toxic, n.o.s.,” UN1851, we propose to add Special Provision 36. The special provision, which limits the maximum net quantity per package at 5 L (1 gallon) for liquids and 5 kg (11 pounds) for solids, is currently assigned to “Medicine, liquid, flammable, toxic, n.o.s.,” UN3248 and “Medicine, solid, toxic, n.o.s.,” UN3249.

—For the entry “Motor fuel anti-knock mixtures,” UN1649, we propose to remove the subsidiary risk hazard from the labeling requirement, and add proposed Special Provision 151. This action is based on a petition for rulemaking (P-1420) we received (see discussion under § 172.102).

—The proper shipping name “Uranium nitrate hexahydrate solution,” UN2980 would be corrected by replacing the word “Uranium” with “Uranyl.” The typographical error occurred in the April 3, 2002 document published in the Federal Register (67 FR 15736).

—The entry “Xylidines, solution,” UN1711 would be revised to read “Xylidines, liquid.”

—In addition to those entries identified above, we are proposing to add the following new entries: “Chlorosilanes, toxic, corrosive, n.o.s.,” UN3361; “Chlorosilanes, toxic, corrosive, flammable, n.o.s.,” UN3362; “Ethylene glycol diethyl ether,” UN1153; “Fibers, animal or fibers, vegetable burnt, wet or damp,” UN1372; “Fibers, vegetable, dry,” UN3360; “4-Nitrophenylhydrazine, with not less than 30% water, by mass,” UN3376; “Organometallic compound, solid, water-reactive, flammable, n.o.s.,” UN3372; “Rags, oily,” UN1856; “Rubber scrap or Rubber shoddy, powdered or granulated, not exceeding 840 microns and rubber content exceeding 45%,” UN1345; “Sodium dinitro-o-cresolate, wetted, with not less than 10% water by mass,” UN3369; “Textile waste, wet,” UN1857; “Trinitrobenzene, wetted, with not less than 10% water by mass,” UN3367; “Trinitrobenzoic acid, wetted, with not less than 10% water by mass,” UN3368; “Trinitrochlorobenzene (picryl chloride), wetted, with not less than 10% water by mass,” UN3365; “Trinitrophenol (picric acid), wetted, with not less than 10% water by mass,” UN3364; “Trinitrotoluene (TNT), wetted, with not less than 10% water by mass,” UN3366 and “Wool waste, wet,” UN1387.

—Various entries would be amended by revising the vessel stowage columns (10A) and/or (10B). The entries include the following: the five “Aerosols,” UN1950 entries; “Ammunition, smoke with or without burster, expelling charge or propelling charge,” UN0303; “Battery fluid, alkali,” UN2797; “Methacrylic acid, stabilized,” UN2531; “Sulfur, molten,” UN2448; and “Urea, nitrate, wetted with not less than 20 percent water, by mass,” UN1357.

Also, see § 172.102 for additional HMT amendments.

Appendix B to § 172.101. In Appendix B to § 172.101, List of Marine Pollutants, we are proposing to revise paragraphs “4” and “5” to update the location in the IMDG Code for the “Guidelines for the Identification of Harmful Substances in Packaged Form.” This update is based on the IMDG Code's change in location from the General Introduction to Chapter 2.10.

In addition, we are removing the entries “Alkylphenols, liquid, n.o.s. (including C2-C12 homologues),” “Alkylphenols, solid, n.o.s. (including C2-C12 homologues),” “Chlorophenols, liquid,” and “Chlorophenols, solid,” from the List of Marine Pollutants. We are revising the entry “Alkylbenzenesulphonates, branched and straight chain” by adding a qualifying phrase to clarify that C11-C13 straight chain or branched chain homologues are not regulated as marine pollutants. Finally, we are adding the entry “Decyl acrylate.”

Section 172.102. We are proposing to amend § 172.102, Special Provisions, as follows:

—Special Provisions 7 and 10 would be removed. These special provisions are assigned to the entries “Ammonium nitrate mixed fertilizers,” NA2069 and “Ammonium nitrate fertilizers,” NA2072, respectively, which we propose to remove (see § 172.101, HMT).

—Special Provision 15, which is assigned to “Chemical kits,” UN3316 and “First aid kits,” UN3316, would be revised by removing the authorized packagings, revising them consistent with packagings authorized for limited quantity exceptions, and relocating them to § 173.161. The proposed Special Provision 15 would specify which chemical and first aid kits apply to the entries; that for transportation by aircraft, materials forbidden by air may not be included in the kits; and that kits carried on board transport vehicles for first aid or operating purposes are not subject to the HMR.

—Special Provision 30 would be revised to include an exception from the placarding requirements for “Sulfur, molten” UN2448 and “Sulfur,” UN1350. Currently, the domestic entries “Sulfur, molten,” NA2448 and “Sulfur,” NA1350 do not require placards because both entries are assigned as Class 9 materials and meet the placarding exceptions for the hazard class in § 172.504(f)(9). We are proposing to provide the same placarding exceptions for the international entries through the revision of Special Provision 30, provided the markings in § 172.325 are applied.

—Special Provision 52 would be editorially revised by removing the wording specific to fertilizers. The special provision, which is currently applied to “Ammonium nitrate fertilizers,” UN2067, would be added to the proposed new entry “Ammonium nitrate emulsion or Ammonium nitrate suspension or Ammonium nitrate gel, intermediate for blasting explosives,” UN3375. The special provision states that a material using the assigned entries may not exhibit explosive properties of Class 1 (explosive) when tested in accordance with the UN Manual of Tests and Criteria, Part I, Test Series 1 and 2.

—Special Provision 130, which excepts dry batteries from the HMR, would be revised by adding the requirement that such batteries must be securely packed and protected against short circuits and by clarifying that dry batteries specifically named in the § 172.101 Table are not eligible for the exception.

—Special Provision 132 would be revised by adding the criteria for which the assigned entry may be used. The special provision would be added to the proposed revised entry “Ammonium nitrate,” UN2071, Class 9. Currently, the special provision provides the criteria for ammonium nitrate fertilizers that are excepted from the HMR.

—Special Provision 133 would be removed. The special provision is currently assigned to “Air bag inflators, compressed gas or Air bag modules, compressed gas or Seat-belt pretensioners, compressed gas” UN3353, Division 2.2, which is proposed to be removed from the HMT (see discussion under § 172.101, HMT.)

—New Special Provision 145 would be added for the existing entry “Hydrogen peroxide and peroxyacetic acids mixtures, stabilized, with acids, water and not more than 5 percent peroxyacetic acid,” UN3149. The special provision describes the formulations for which this entry would apply.

—New Special Provision 146 would be added for the entries “Environmentally hazardous substances, liquid, n.o.s.,” UN3082 and “Environmentally hazardous substances, solid, n.o.s.,” UN3077 to clarify that the entries may be used to describe materials that pose a hazard to the environment but do not meet the definition of a hazardous waste, hazardous substance or any hazard class as defined in the HMR. This includes materials or wastes that are designated as environmentally hazardous by the Competent Authority of the country of origin.

—New Special Provision 147 would be added for assignment to the proposed new entry, “Ammonium nitrate emulsion or Suspension or Gel, intermediate for blasting explosives,” UN3375. The special provision describes the composition of the material for which the use of the entry would be authorized and prohibits the material from being classified and transported unless approved by the Associate Administrator.

—New Special Provision 149 would be added to the Packing Group II entries for 14 existing proper shipping names. The special provision would allow the maximum net capacity for inner packagings to be increased to no more than 5 L (1.3 gallons) when the material is transported as a limited quantity. The 14 entries are: “Adhesives, containing a flammable liquid,” UN1133; “Coating solution (includes surface treatments or coatings used for industrial or other purposes such as vehicle undercoating, drum or barrel lining),” UN1139; “Extracts, aromatic, liquid,” UN1169; “Extracts, flavoring, liquid,” UN1197; “Printing ink, flammable or Printing ink related material (including printing ink thinning or reducing compound), flammable,” UN1210; “Paint including paint, lacquer, enamel, stain, shellac solutions, varnish, polish, liquid filler, and liquid lacquer base,” UN1263; “Paint related material including paint thinning, drying, removing, or reducing compound,” UN1263; “Perfumery products with flammable solvents,” UN1266; “Rubber solution,” UN1287; “Wood preservatives, liquid,” UN1306; “Resin solution, flammable,” UN1866; “Tars, liquid including road asphalt and oils, bitumen and cut backs,” UN1999; “Alcoholic beverages,” UN3065; and “Polyester resin kit,” UN3269 for Packing Group II resin kits as specified in Special Provision 40.

—New Special Provision 150 would be added for assignment to the entry “Ammonium nitrate based fertilizer,” UN2067 to authorize the use of the entry for uniform mixtures containing ammonium nitrate as the main ingredient within certain composition limits.

—New Special Provision 151 would be added for assignment to the proposed new entry “Hydrazine aqueous solution, with more than 37% hydrazine, by mass” UN2030, Packing Group I and to the existing entry “Motor fuel anti-knock mixtures,” UN1649. The special provision requires a packaging containing a material meeting the definition of a flammable liquid to display a flammable liquid label, and requires a Class 3 subsidiary hazard to be shown on shipping papers.

With regard to the entry “Motor fuel anti-knock mixtures,” UN1649, we received a petition for rulemaking (P-1420) requesting that we remove the flammable subsidiary risk for this entry. The petitioner stated that the international standards do not assign the entry a flammable subsidiary risk and that the inconsistency with the HMR causes a regulatory compliance burden when transporting the material internationally. The petitioner stated that removing the subsidiary risk is additionally justified because motor fuel anti-knock mixtures containing tetramethyl lead, with fire points greater than 54 °C (129.2 °F) are no longer manufactured or transported. Although the UN Recommendations, the ICAO Technical Instructions and the IMDG Code do not assign a flammable subsidiary risk to the entry, all three standards assign a special provision stating that mixtures with a flashpoint of less than 60.5 °C (141 °F) must bear a flammable liquid subsidiary risk label. We are proposing to remove the flammable subsidiary risk from the label requirements in Column (6) of the HMT for “Motor fuel anti-knock mixtures,” UN1649 and add a new Special Provision 151 to require a flammable liquid subsidiary label only when the mixtures have a flashpoint of less than 60.5 °C (140.9 °F). Also, see preamble text under the § 172.101 Table changes.

—New Special Provision 153 would be added to the five “Aerosols,” UN1950 entries to provide the criteria for classifying aerosols.

—New Special Provision 155 would be added to two entries, “Fish meal, stabilized or Fish scrap, stabilized,” UN2216 and “Fish meal, unstabilized or Fish scrap, unstabilized,” UN1374. The special provision specifies that if the temperature of fish scrap at the time of loading either exceeds 35 °C (95 °F), or exceeds 5 °C (41 °F) above the ambient temperature, whichever is higher, the fish scrap may not be transported. Also see § 173.218 for additional discussion.

—New Special Provision 156 would be added for assignment to three entries, “Blue asbestos (Crocidolite) or Brown asbestos (amosite, mysorite),” UN2212, “White asbestos (chrysotile, actinolite, anthophyllite, tremolite),” UN2590, and “Asbestos,” NA2212. The special provision provides an exception from the HMR for certain asbestos. The exception, which is currently in § 173.216(b), excepts asbestos immersed or fixed in a natural or artificial binder material and asbestos contained in manufactured products. We received comments that the current § 173.216 location for this exception is not appropriate because it is referenced in the non-bulk column of the HMT, leading readers to believe that the exception applies to non-bulk packagings only. To clarify that this exception applies to both non-bulk and bulk packagings, we are proposing to move the exception from § 173.216(b) to proposed Special Provision 156.

—New Special Provision 157 would be added to the entries “Vehicle, flammable gas powered,” and “Vehicle, flammable liquid powered,” each of which is assigned to UN3166. The proposed special provision specifies that the use of the entries includes hybrid electric vehicles powered by both internal combustion engines and wet, sodium or lithium batteries.

—New Special Provision 159 would be added to the entry “5-tert-Butyl-2,4,6-trinitro-m-xylene or Musk Xylene,” UN2956. The special provision requires this material to be protected from direct sunshine and kept in a cool, well-ventilated place away from sources of heat.

—New Special Provision 160 would be added to the entry “Air bag inflators, or Air bag modules, or Seat-belt pretensioner,” UN3268, Class 9. The special provision includes the requirement that air bag inflators and modules must be tested in accordance with Test series 6(c) of Part I of the UN Manual of Tests and Criteria, and also includes an exception from testing air bag modules that contain an inflator previously approved for transportation. Also, see § 172.102, HMT, which includes additional proposed revisions such as removing the italicized word “pyrotechnic” from the UN3268 entry.

—New Special Provision 161 would be added to the entry “Air bag inflators, pyrotechnic or Air bag modules, pyrotechnic or Seat-belt pretensioner, pyrotechnic,” UN0503, Division 1.4G. The special provision specifies that the UN0503 entry may not be used for domestic transportation, and that the more appropriate description is “Articles, pyrotechnic for technical purposes,” UN0431. We are specifically requesting comments concerning whether this may result in an unnecessary burden for international shippers. We are not aware of any air bag inflators that are transported as Division 1.4G in the United States. Also, see § 172.102, HMT, which includes the proposed amendment to remove the italicized word “pyrotechnic” from the UN0503 entry.

—New Special Provision 162 would be added to eight proposed entries and two existing entries. The Special Provision authorizes the material to be transported under the provisions of Division 4.1, only if it is so packed that at no time during transport will the percentage of diluent fall below the percentage that is specified in the proper shipping name. The proposed new entries are “4-Nitrophenylhydrazine, with not less than 30% water, by mass,” UN3376; “Sodium dinitro-o-cresolate, wetted, with not less than 10% water by mass,” UN3369; “Trinitrobenzene, wetted, with not less than 10% water by mass,” UN3367; “Trinitrobenzoic acid, wetted, with not less than 10% water by mass, UN3368; “Trinitrochlorobenzene (picryl chloride), wetted, with not less than 10% water by mass,” UN3365; “Trinitrophenol (picric acid), wetted, with not less than 10% water by mass,” UN3364; “Trinitrotoluene (TNT), wetted, with not less than 10% water by mass,” UN3366; and “Urea nitrate, wetted, with not less than 10% water by mass,” UN3370. The two existing entries are “Barium azide, wetted with not less than 50 percent water, by mass,” UN1571 and “Dipicryl sulfide, wetted with not less than 10 percent water, by mass,” UN2852.

—New Special Provisions A54 and A55 would be added to address certain requirements for the transportation of lithium batteries by aircraft. Special Provision A54 provides an approval provision that authorizes lithium batteries and lithium batteries contained in equipment or packed with equipment to exceed the quantity limits as specified in Column (9B) of the HMT when transported by cargo aircraft, if approved by the Associate Administrator. Special Provision A55 provides an approval provision to authorize prototype batteries to be transported by cargo aircraft if approved by the Associate Administrator. Special Provisions A54 and A55 would be assigned to “Lithium battery,” UN3090, “Lithium batteries, contained in equipment,” UN3091 and “Lithium batteries packed with equipment,” UN3091.

—New Special Provision A56 would be added to address the air transport of radioactive material with subsidiary hazards of Divisions 4.2, Packing Group I, 2.1 or 2.3. Division 4.2, Packing Group I subsidiary hazard materials would be required to be transported by aircraft in Type B packagings only. Division 2.1 subsidiary hazard materials would be prohibited from passenger aircraft. The special provision is in alignment with the ICAO Technical Instruction's Special Provision A78, with regard to radioactive materials with Division 2.1 subsidiary hazard but not the Division 4.2, PG I packaging requirement or the Division 2.3 subsidiary hazard approval provision. Proposed Special Provision A56 includes Division 4.2, PG I because we believe it was inadvertently omitted in ICAO's Special Provision A78, and we understand that steps are being taken to address the matter with the ICAO Dangerous Goods Panel. See the § 172.101 HMT in the regulatory text of this rule for specific entries.

—Special Provision IB3 would be revised by excepting “Ammonia solutions, relative density between 0.880 and 0.957 at 15 degrees C in water, with more than 10 percent but not more than 35 percent ammonia,” UN2672 from the special provision's “Additional Requirement” that authorizes liquids with a vapor pressure less than or equal to 110 kPa at 50 °C (1.1 bar at 122 °F), or 130 kPa at 55 °C (1.3 bar at 131 °F). Proposed new Special Provision IP8 would also be added to the UN2672 entry.

—Special Provision IB52 (Table 2) would be revised by adding additional packaging authorizations for certain entries and correcting various typographical errors. The entry “Dicumyl peroxide, “UN3110 would be corrected by adding “2000” as the maximum quantity in liters. In addition, we are proposing to move the approval provision for formulations not covered in Special Provision IB52 to § 173.225(e)(5). Section 173.225(e) currently contains an approval provision for portable tanks, and we believe this paragraph is a more appropriate location for the IB52 approval provision.

—New Special Provision IP8 (Table 3) would be added for assignment to the existing entry “Ammonia solutions, relative density between 0.880 and 0.957 at 15 degrees C in water, with more than 10 percent but not more than 35 percent ammonia,” UN2672 (see Special Provision IB3). The special provision authorizes ammonia solutions to be transported in rigid or composite plastic intermediate bulk containers (IBCs) (31H1, 31H2 and 31HZ1), if the rigid plastic and composite IBCs have successfully passed, without leakage or permanent deformation, the hydraulic test specified in § 178.814 at a test pressure that is not less than 1.5 times the vapor pressure of the contents at 55 °C (131 °F).

—New Special Provision N83 would be added to the proposed new entry “Urea nitrate, wetted, with not less than 10% water by mass,” UN3370. This special provision limits the quantity of this material to no more than 11.5 kg (25.4 lbs) per package.

—New Special Provision N84 would be added for assignment to six proposed new entries and one existing entry. The special provision limits the quantity per package to no more than 500 g (1.1 lbs.). The six proposed new entries are: “Trinitrophenol (picric acid), wetted, with not less than 10% water by mass,” UN3364; “Trinitrochlorobenzene (picryl chloride), wetted, with not less than 10% water by mass,” UN3365; “Trinitrotoluene (TNT), wetted with not less than 10% water by mass,” UN3366; “Trinitrobenzene, wetted, with not less than 10% water by mass,” UN3367; “Trinitrobenzoic acid, wetted, with not less than 10% water by mass,” UN3368; and “Sodium Dinitroocresolate, wetted, with not less than 10% water by mass,” UN3369. The existing entry is “Dipicryl sulfide, wetted with not less than 10 percent water, by mass,” UN2852.

—New Special Provision N85 would be added for assignment to two existing entries, “Isosorbide dinitrate mixture with not less than 60 percent lactose, mannose, starch or calcium hdrogen phosphate,” UN2907 and “Pentaerythrite tetranitrate mixture, desensitized, solid, n.o.s. with more than 10 percent but not more than 20 percent PETN, by mass,” UN3344. The special provision prohibits the material from being transported in packagings conforming to the requirements of Part 178 of the HMR at the Packing Group I performance level. This proposed action would address overconfinement hazards associated with these materials by prohibiting the use of packagings meeting the Packing Group I performance criteria.

—Special Provision T23 would be revised to correct typographical errors for the entries “tert-Butyl peroxyacetate, not more than 32% in diluent type B” and “tert-Butyl peroxypivalate, not more than 27% in diluent type B.” The word “tyupe” would be corrected to read “type” in the former and the control “temperature, −5 °C,” would be corrected to read “+5 °C.”

—Special Provision TP3 would be editorially revised for clarity.

Section 172.202. We are proposing to revise paragraphs (a)(2), (a)(5) and (b). In paragraph (a)(2), we are proposing to require the subsidiary hazard class or subsidiary division number(s) to be entered in parentheses following the primary hazard class or division number on shipping papers. This requirement is currently required only for transportation by vessel. This proposed requirement responds to three petitions for rulemaking, P-1363, P-1398 and P-1402. One petitioner (P-1363) stated that the lack of such a requirement poses problems for motor carriers with regard to complying with segregation, separation and placarding requirements, as well as posing a safety hazard. The petitioner pointed out that when the hazardous materials being transported include a subsidiary hazard such as “dangerous when wet” or a subsidiary hazard requiring more stringent requirements than the primary hazard, there is no indication of the subsidiary hazards on the shipping papers and no indication of the subsidiary risks on placards. The petitioner stated that when motor vehicles are being loaded at a dock, labels are not enough to alert hazardous materials employees loading the vehicles or emergency responders of the subsidiary risks of materials in the vehicle.

Two petitions (P-1398 and P-1402) were specific to Division 4.3 materials. The petitioners requested that we require the shipping paper to contain the words “dangerous when wet” following the basic description for hazardous materials classed as Division 4.3 or having a Division 4.3 subsidiary hazard. The petitioners stated that the additional information would aid emergency responders by more clearly identifying the hazard.

We agree with the petitioners with regard to their request to require that subsidiary hazard class or subsidiary division number(s) be entered on the shipping paper. Thus, we are proposing to add a requirement to identify all subsidiary risks of a hazardous material on the shipping paper. We do not agree, however, with the suggestion to adopt the same requirement for the primary hazard class. We believe that this is unnecessary because the primary hazard is clearly identified on shipping papers by the division number as part of the basic description. We also do not agree with the petitioner's (P-1363) suggestion to provide an exception from the proposed requirement to include the subsidiary hazard on shipping papers when the subsidiary hazard is identified in the proper shipping name (for example, “Flammable liquid, toxic, n.o.s.”). This suggested approach would be inconsistent with the UN Recommendations and would result in the addition of a domestic exception that would not enhance hazard communication and could also lead to frustrated international shipments while unnecessarily complicating the HMR.

We are also proposing to revise paragraph (a)(5) regarding the indication on shipping papers of the total quantity of hazardous materials. The proposed requirement, which is currently optional for all modes of transportation other than vessel, would make it mandatory for shippers to indicate on shipping papers the types of packages, such as drums, boxes, jerricans, etc., being used to transport hazardous materials by all modes of transportation. This requirement is consistent with international standards. We invite comments on costs, benefits, and complications that could result from adoption of this requirement. For example, certain electronic shipping paper programs, materials transported under a single basic description that are packaged in more than one type of packaging possibly would need to be listed more than once on the shipping paper. Alternatively, alterations to those programs may be necessary to provide space required to list more than one type of package for a single basic description. Therefore, we request comments addressing these issues, including suggestions to minimize any impacts associated with this proposed change, such as providing an extended transition period. For the purpose of consolidation, we would also transfer to this paragraph the existing additional requirements for transportation by vessel currently located in § 172.203 (i)(1), (i)(2), (i)(3) and (i)(6).

In addition, paragraph (b) would be revised to allow, as an alternative to the basic description sequence currently required in this paragraph, the identification number to be listed first on shipping papers and the proper shipping name to be listed following the hazard class and subsidiary risk. Noting that international standards will allow both sequences, we request comments specific to whether we should incorporate this amendment as an alternative for all shipments to, from, or within the U.S., or whether we should allow it for international shipments only. We also ask for comments addressing the impact this proposed amendment may have on emergency response training.

Section 172.203. We are proposing to remove and relocate paragraphs (i)(1), (i)(2), (i)(3) and (i)(6). With adoption of the proposal to indicate types of packagings on shipping papers in § 172.202, we would consolidate the four vessel requirements in § 172.203(i) by moving them to the description requirements in § 172.202(a)(5). The paragraphs address additional shipping paper requirements for the identification of the type, number and gross mass of packagings, and the identification of subsidiary hazards consistent with international standards. The current paragraphs (i)(4) and (i)(5) would be redesignated (i)(1) and (i)(2).

Section 172.301. Paragraph (a)(1) would be revised to reflect the proposed new marking requirement in § 172.315 for packagings containing limited quantities of hazardous materials. Packagings containing limited quantities would no longer require the proper shipping name on the packagings, but would be required to be marked in accordance with the proposed § 172.315 marking requirement that consists of an identification number placed within a diamond. (See § 172.315).

Section 172.312. A new paragraph (c)(6) would be added to allow packages containing liquid infectious substances in primary receptacles not exceeding 50 ml (1.7 oz) to be excepted from the requirements in § 172.312(a). Section 172.312(a) requires liquid hazardous materials packaged in non-bulk combination packagings to be packed with closures upward and to be legibly marked with orientation markings.

Section 172.315. A new section, § 172.315, would be added as a new marking requirement for packagings containing limited quantities of hazardous materials. This section would require such packagings to be marked with the identification (ID) number placed within a diamond. Marking the proper shipping name on limited quantity packagings would not be required. The line forming the diamond would be required to be at least 2 mm thick and the height of the ID number no less than 6 mm. For packagings containing more than one limited quantity of hazardous materials with different ID numbers, the packaging would be required to be marked with either individual diamonds bearing a single ID number, or a single diamond large enough to include each applicable ID number. The marking would be required to be durable, legible and of a size relative to the packaging as to be readily visible.

Section 172.323. A new section, § 172.323, would be added to incorporate an air eligibility marking requirement into the HMR for all non-bulk packages offered for transportation or transported by aircraft. The marking would certify compliance with all applicable air transport package requirements, including pressure differential requirements, package markings and labels, inner packaging limits, selection of appropriate types of packagings, use of closure instructions for inner packagings, application of the cargo aircraft handling label (when applicable), and proper classification.

The ICAO has adopted this requirement in the 2003-2004 edition of the ICAO Technical Instructions, and a number of packaging vendors and military shippers are currently marking packagings to indicate that they meet the additional air requirements through the use of an air eligibility symbol, such as we are proposing, or by use of the statement “Air Eligible.” In addition to consistency with the ICAO Technical Instructions, we believe that the use of an air eligibility mark would be beneficial in heightening shipper awareness and responsibility for meeting the additional air transport package requirements. Adoption of this requirement would reduce the inadvertent acceptance for transportation by aircraft of packages that conform only to highway, rail or vessel requirements.

The shipper would be responsible for the application of the marking, but would not be required to physically place it on the package. The marking could be applied by using a durable sticker or label, preprinting it on the packaging, or drawing it on the package by hand. The marking would be required to be durable, legible, and of such size relative to the packaging as to be readily visible. Preprinting by the package manufacturer would require the manufacturer and the shipper to closely coordinate to ensure that the package meets the applicable air transport requirements. The shipper would be responsible for ensuring that the package meets the applicable air transport requirements.

Section 172.411. We are proposing to revise the section heading and paragraphs (b) and (d), and to add new paragraphs (e) and (f). In the June 21, 2001 HM-215D final rule, we removed the requirement to differentiate between primary and subsidiary labels by requiring the class number to be displayed on both types of labels. The primary explosive label requires the appropriate division number and compatibility group to be displayed, but the explosive subsidiary label does not. This disparity was an oversight, and we are proposing to correct this section by adding the pictorial of the explosive subsidiary label and revising the text accordingly.

Section 172.504. Based on a telephone call we received from a shipper, paragraph (g) would be editorially revised by adding a clarification emphasizing the distinction between the words “explosive articles” and “explosive substances.” The commenter stated that the paragraph is often misinterpreted because the two phrases are not understood as having different meanings.

Part 173

Section 173.2a. In paragraph (b), the second line of the title of the Precedence of Hazard Table is editorially revised to include the word “division.” In addition, the Table is revised for the first three entries by inserting “4.3” under the Division 4.3 column to indicate that Division 4.3 takes precedence over Class 3 when classifying a material having more than one hazard.

Section 173.21. In paragraph (f)(3)(ii), we are proposing to update the location reference to the control temperature requirements in the IMDG Code to its current location in Chapter 7.7.

Section 173.22. We are proposing to revise paragraph (a)(4) to clarify that, in addition to complying with the Part 178 requirements, the shipper is responsible for ensuring that packages comply with the Part 173 requirements. This revision is consistent with the proposed amendments to § 173.24a relative to closures, and to § 173.27 relative to packages intended for air transport.

Section 173.24. A new paragraph (b)(4) would be added and paragraph (f)(1) would be revised. Paragraph (b)(4) would be revised by adding general requirements applicable to the integrity of packagings. The revision would amend the requirement that packagings must be closed in accordance with the closure instructions provided by the manufacturer. Paragraph (f)(1) would be revised to address requirements for the construction and design of closures.

Section 173.25. In paragraph (a)(2), for the marking requirements pertaining to overpacks, we are proposing to include the air eligibility marking as proposed in § 172.323.

Section 173.27. We are proposing to revise paragraph (e) and add a new paragraph (i).

Paragraph (e) would be revised to require packagings with plastic and metal inner packagings to be packaged using absorbent material when Packing Group I or II liquids of Class 3, 4 or 8 or Division 5.1, 5.2 or 6.1 are offered for transport by passenger or cargo aircraft. Currently, the requirement to use absorbent material applies to Packing Group I and II materials when offered for transport by passenger aircraft, and to Packing Group I materials when offered for transport by cargo aircraft. We are proposing to also apply this requirement to Packing Group II materials offered for transport by cargo aircraft. Existing absorbent material requirements apply when inner packagings are constructed of glass or earthenware. The absorbent material requirement currently does not apply to Division 5.2 liquids. Various air carriers are currently imposing such a requirement, and it has been adopted in the 2003-2004 edition of the ICAO Technical Instructions, effective January 1, 2003. Therefore, offerors and shippers will be required to meet these requirements when air transport is in accordance with the ICAO Technical Instructions regardless of whether the requirements are incorporated into the HMR.

We are proposing to add a new paragraph (i) to refer the reader to proposed new section § 172.323 for the air eligibility marking requirement for packagings containing hazardous materials being transported by aircraft. See § 172.323 for the discussion on this proposed requirement.

Section 173.62. In § 173.62, in the paragraph (b) Explosives Table, the entry “UN0503” would be added for assignment to the packing instruction P135. UN0503 is assigned to the proper shipping name “Air bag inflators, or Air bag modules, or Seat-belt pretensioners,” Division 1.4G (also see § 172.101, HMT). The Class 9 “Air bag inflators, or Air bag modules, or Seat-belt pretensioners” entry would continue to be packaged in accordance with § 173.166.

In addition, in paragraph (c), in the Explosives Packing Instructions Table, in the first column, for the packing instruction entry 112(b), in the last sentence, the obsolete ID number, “UN 0223,” would be removed. The entry was removed from the § 172.101 Table in a separate rulemaking.

Section 173.115. In paragraphs (d) and (e), we are proposing to amend the regulatory text that describes “non-liquefied compressed gas” and “liquefied compressed gas.” The proposed amendment would revise the reference temperature from 20 °C to −50 °C, consistent with internationally accepted definitions for gases and consistent with the twelfth edition of the UN Recommendations.

We are also proposing to divide compressed liquefied gases into high and low pressure categories. The UN Subcommittee revised the terminology for gases to align them with the terminology used in the International Organization for Standardization (ISO) Standard 10286. This standard establishes the terminology applicable to gas cylinders and provides definitions for gases. The proposed regulatory text would affect 11 entries in the § 172.101 Table by removing the word “compressed” from the proper shipping names. Under a separate rulemaking, we will address whether the affected gases should be reassigned to more appropriate packagings sections, such as revising the packaging authorization from § 173.302 to § 173.304 in Column (8B) in the § 172.101 Table. We will also address the use of the high- and low-pressure compressed liquefied gas designations.

Sections 173.152, 173.153 and 173.154. The following sections would be revised by increasing the inner packaging net capacity limit for Packing Group III liquids from 4 L (1.1 gallons) to 5 L (1.3 gallons): § 173.152(b)(2), exceptions for Division 5.1 oxidizers and Division 5.2 organic peroxides; § 173.153(b)(1), exceptions for Division 6.1 poisonous materials; and § 173.154(b)(2), exceptions for Class 8 corrosive materials. Section 173.152(b)(4)(ii) would also be revised by raising the net capacity of inner packagings containing PG II flammable liquids in polyester resin kits from 1 L (0.3 gallons) to 5 L (1.3 gallons) each.

Section 173.159. A new sentence would be added to paragraph (a) requiring packagings for certain batteries to include an acid/alkali proof liner or a supplementary packaging with sufficient strength and adequate sealant to prevent leakage of electrolyte fluid in the event of spillage. This requirement would apply to packagings transported by aircraft and containing electric storage batteries with electrolyte acid or alkaline corrosive battery fluid.

A new paragraph (d)(4) would be added to require non-spillable batteries, that are excepted from all other requirements of the HMR, to meet the condition that at a temperature of 55 °C (131 °F), the electrolyte will not flow from a ruptured or cracked case and there is no free, unabsorbed liquid in the battery.

Section 173.161. We are proposing to revise this section to specify the packaging requirements for chemical and first aid kits consistent with international standards.

Section 173.166. This section would be revised consistent with the proposed removal of the Division 2.2 entry for “Air bag inflators, compressed gas or Air bag modules, compressed gas or Seat-belt pretensioners, compressed gas,” UN3353 (see § 172.101, HMT). We are proposing in this section to authorize reclassification to Class 9 without further testing for air bag inflators, air bag modules and pretensioners currently approved for transportation as Division 2.2.

Section 173.185. Paragraphs (e)(4) and (e)(7) would be revised and a new paragraph (k) would be added. We are proposing to combine paragraphs (e)(4) and (e)(5) into one paragraph, (e)(4), and to remove and reserve paragraph (e)(5).

The proposed revised paragraph (e)(4) would allow the use of dividers or other suitable means as alternative methods to inner packagings for effective means of preventing short circuits of lithium cells and batteries.

Based on a comment that was beyond the scope of the HM-215D final rule, we are proposing to revise paragraph (e)(7) by applying the prohibition to offer for transportation or transport certain cells and batteries to only those with a liquid cathode containing sulfur dioxide, sulfuryl chloride or thionyl chloride. Currently, any cell or battery with a cell that has been discharged to the extent that the open circuit voltage is less than 2 volts, or less than two-thirds of the open circuit voltage of the fully charged cell, whichever is less, is prohibited from being offered for transportation or transported. We have included sulfuryl chloride in this proposal and specifically request comments on whether these types of batteries exist to determine whether it is necessary to include sulfuryl chloride batteries and cells in this amendment. The UN Recommendations do not include this prohibition. The reduced voltage condition was included in the HMR to address lithium sulfur dioxide, sulfuryl chloride and lithium thionyl chloride primary batteries on the basis of safety issues with low-voltage cells. The lithium sulfur dioxide batteries present hazards in transportation when the sulfur dioxide is depleted. The depletion can cause the removal or breakdown of the passivation film on the lithium anode which could result in a undesirable exothermic reaction of the lithium metal and the electrolyte solvent leading to high temperatures, cell venting, cell rupture, and fires. In addition, a new paragraph (k) would be added to allow batteries with a mass of 12 kg or greater and having strong, impact-resistant outer casings to be packed in strong outer packagings, protective enclosures, or unpacked on pallets. Packaging in this manner for transportation by cargo-only aircraft would be permitted only with the approval of the Associate Administrator.

Additional amendments to the requirements for lithium batteries are being addressed in a separate rulemaking, under Docket HM-224C (NPRM published on April 2, 2002, 67 FR 15510). One of the proposals under Docket HM-224C addresses a reorganization of § 173.185. Any amendments adopted in either final rule will be reflected in the other.

Section 173.216. We are proposing to move the exceptions for asbestos in paragraph (b) to a new special provision (see Special Provision 156 in § 172.102). Paragraph (b) excepts asbestos immersed or fixed in a natural or artificial binder material and also excepts asbestos contained in manufactured products. We understand that because the exception is located in § 173.216 and referenced in Column (7) of the HMT for non-bulk packagings, the exception appears to be limited to non-bulk packagings. To clarify the applicability, we are proposing to remove and reserve paragraph (b) and transfer the exception to the proposed new Special Provision 156. The exception will continue to apply to three entries, “Blue asbestos (Crocidolite) or Brown asbestos (amosite, mysorite),” UN2212, “White asbestos (chrysotile, actinolite, anthohyllite, tremolite),” UN2590, and “Asbestos,” NA2212.

Section 173.218. Paragraph (a) introductory text would be revised and paragraph (b) would be removed. Paragraph (a) introductory text would be editorially revised to reflect the proposed relocation of the requirement currently contained in paragraph (b). In the current paragraph (b), the requirement for the maximum temperature at which fish meal or fish scrap may not be offered for transportation would be revised from 49 °C (120 °F) to 35 °C (95 °F), or 5 °C (41 °F) above ambient temperature, whichever is higher, and relocated to proposed Special Provision 155 (see § 172.102).

Section 173.220. We are proposing to add a new paragraph to include additional requirements for certain engines and vehicles. The current paragraph (e) would be redesignated (f) and the new paragraph would become paragraph (e). The new paragraph would include several additional requirements for internal combustion engines and vehicles equipped with certain devices when transported by aircraft or vessel. When engines are shipped separately, we are proposing that all fuel, coolant or hydraulic systems in or on the engine must be drained as far as practicable, must have disconnected fluid pipes sealed with leak-proof caps that are positively retained, and any installed theft-protection devices, radio communications equipment or navigational systems must be disabled.

Section 173.223. We are proposing to add a new packaging section, § 173.223, for musk xylene. Currently, the authorized packaging section, § 173.214, for musk xylene requires approval by the Associate Administrator. We are proposing to add a new section that is consistent with the UN packing instruction P409 assigned to musk xylene, so that approval by the Associate Administrator will no longer be necessary.

Section 173.224. In paragraph (b)(4), the incorrect reference for bulk packaging authorizations, § 173.225(d), would be corrected to read § 173.225(e). In the Self-Reactive Materials Table following paragraph (b)(7), five entries in Column (1) would be revised and four new entries would be added. The five revised entries appear first as “removes” and then “adds” in the regulatory text section of this NPRM. For the entry “2,2'-Azodi(isobutryonitrile) as a water based paste,” the misaligned column entries would be corrected. A new Note 4 would be added following the table for assignment to the new entry “2-Diazo-1Naphthol sulphonic acid ester mixture, Type D.”

Section 173.225. We are proposing to amend the paragraph (b) Organic Peroxide Table, the Notes following the Table, and paragraphs (e)(3)(xii) and (e)(5).

The proposed amendments to the Organic Peroxide Table include the addition of bulk and IBC packaging authorizations for certain entries, the addition of several new entries and various corrections to certain entries.

Note 9 following the Table would be revised by correcting the paragraph reference “(e)(3)(ii)” to read “(e)(3)(xii).” A new Note 27 would be added for the proposed entry “Peroxyacetic acid, distilled, Type F, stabilized,” UN3110. A new Note 28 would be added to clarify that “Peroxyacetic acid” and Peracetic acid” are synonymous.

Paragraph (e)(3)(xii) would be revised to clarify that DOT Specification 57 portable tanks are not subject to any other requirements in paragraph (e).

We are also proposing to move the approval provisions currently contained in the § 172.102(c)(4) Table 2, Special Provision IB52, to paragraph (e)(5). We believe this is a more appropriate section for the approval provisions, which we are proposing to expand to provide for the use of IBCs other than those indicated in the IB52 Table when approved by the Associate Administrator.

Section 173.244. We are proposing to revise paragraph (c) by adding a clarification that UN portable tanks are also authorized for use if a T code is specified in Column (7) of the HMT for the specific hazardous material.

Section 173.306. We are proposing to revise the paragraph heading in § 173.306(f) by adding the proper shipping name “Articles, pressurized, pneumatic or hydraulic containing non-flammable gas.” The revision is based on the proper shipping name replacing the domestic entry “Accumulators, pressurized, pneumatic or hydraulic (containing non-flammable gas),” which was removed in HM-215D published on June 21, 2001. We received telephone calls requesting the addition to the paragraph heading to clarify the intent of the paragraph.

We are also proposing to add a new paragraph (j) to reference the exception for certain compressed gases in § 173.307.

Section 173.307. We are proposing to add a new paragraph (a)(5) to except Division 2.2 gas aerosols with a capacity of not more than 50 ml and with a pressure not exceeding 970 kPa (141 psig) from the HMR.

Section 173.422. We are proposing to revise the certification statements in paragraphs (a)(2), (a)(3) and (a)(4) to reflect the updated proper shipping names and UN identification numbers currently authorized in the § 172.101 Table for excepted packages of radioactive materials.

Part 175

Section 175.10. We are proposing to revise paragraph (a)(25) to allow two small CO₂ cartridges fitted in self-inflating life jackets and two spare cartridges to be carried by a passenger or crew member in checked or carry-on baggage. Currently, paragraph (a)(25) allows, with the approval of the aircraft operator, one small carbon dioxide cylinder fitted into a self-inflating life-jacket, plus one spare cartridge.

We are also proposing to add a new paragraph (c) to extend the paragraph (a) exceptions from the HMR to aircraft operators when transporting baggage that has been inadvertently separated from a passenger or crew member before reaching its final destination.

Section 175.30. We are proposing to add a new paragraph (a)(5) requiring that the proposed air eligibility marking requirement in § 172.323 must be met before a person may accept hazardous materials for transportation by aircraft.

Section 175.90. We are proposing to revise paragraphs (b) and (c). Paragraph (b) would be revised to include amendments relative to an aircraft operator's responsibility concerning packagings, baggage or cargo that have become contaminated by leaking hazardous materials. This proposal is consistent with the 2003-2004 edition of the ICAO Technical Instructions and is in response to a National Transportation Safety Board (NTSB) recommendation (A-96-30) issued to the Federal Aviation Administration. This NTSB recommendation resulted from an incident involving an undeclared shipment of a hydrogen peroxide solution that leaked, resulting in injuries to airline personnel and a potential fire hazard aboard a passenger aircraft. Paragraph (c) prohibits a person from placing a damaged packaging aboard an aircraft. We are proposing to revise the paragraph by including the words “baggage or cargo” when referring to a damaged or leaking packaging.

Part 176

Section 176.27. In paragraph (c)(2), we are proposing to remove the words “of 49 CFR 176.27(c)” at the end of the certification statement and add the words “of 49 CFR” or “of the IMDG Code.”

Section 176.63. We are proposing to add a new paragraph (f) to include the conditions for the authorized stowage of containers on board hatchless container ships.

Section 176.83. We are proposing to add a new paragraph (l) to include the requirements for the segregation of containers on board hatchless container ships.

Section 176.84. In the paragraph (b) Table of Provisions, we are proposing to add nine new provisions (codes) for certain stowage and segregation requirements for hazardous materials that are transported by vessel. The terms “separated from” and “away from” in the proposed codes are defined in § 176.83 of the HMR.

Code 124 would be added for assignment to the proposed new entry “Ammonium nitrate emulsion or Ammonium nitrate suspension or Ammonium nitrate gel, intermediate for blasting explosives,” UN3375 and would require the material to be stowed “separated from” bromates.

Code 125 would be added for assignment to the proposed new entry “Chlorosilanes, toxic, corrosive, flammable, n.o.s.,” UN3362 and would require segregation to be the same as for flammable liquids; however, those materials also would be required to be “away from” flammable solids.

Code 126 would be added for assignment to the five current UN1950 aerosol entries and would require segregation to be the same as for Class 9 miscellaneous hazardous materials.

Code 127 would be added for assignment to “5-tert-Butyl-2,4,6-trinitro-m-xy-xylene,” UN2956 and would require packagings carrying a subsidiary risk of Class 1 (explosives) to be segregated as required for Class 1, Division 1.3.

Code 128 would be added for assignment to “Fish meal, stabilized,” UN2216 and “Fish meal, unstabilized,” UN1374 and would require stowage to be in accordance with the IMDG Code, sub-section 7.1.10.3.

Code 129 would be added for assignment to “Radioactive material, low specific activity (LSA-I) non fissile or fissile-excepted,” UN2912 (the international entry); “Radioactive material, low specific activity, n.o.s. or Radioactive material, LSA, n.o.s.,” UN2912 (the domestic entry); “Radioactive material, low specific activity (LSA-II) non fissile or fissile-excepted, “UN3321; and “Radioactive material, low specific activity (LSA-III) non fissile or fissile excepted,” UN3322. This code would require stowage to be in accordance with Stowage Category A, with certain exceptions noted.

Code 130 would be added for assignment to “Radioactive material, Type A package non-special form, non fissile or fissile-excepted,” UN2915 to require Stowage Category A. Certain exceptions are noted.

Code 131 would be added for assignment to “Radioactive material, Type A package, fissile non-special form,” UN3327 to require Stowage Category A, with certain exceptions noted.

Code 132 would be added for assignment to “Uranium hexafluoride, fissile (with more than 1 percent U-235),” UN2977; “Uranium hexafluoride, fissile excepted or non-fissile,” UN2978; “Radioactive material, uranium hexafluoride, fissile,” UN2977; and “Radioactive material, uranium hexafluoride non fissile or fissile-excepted,” UN2978. This code requires stowage to be in accordance with Stowage Category A and note that any supplementary requirements specified in the transport documents must be considered.

Section 176.140. The reference to the IMDG Code in paragraph (b) would be updated by removing the wording “General Introduction.”

Section 176.170. Paragraph (b) would be removed and reserved. For alignment with a revision made in Amendment 31 of the IMDG Code, we are removing the requirement that prohibits freight containers exceeding 6 m (20 feet) in length from carrying more than 5000 kg (11,023 pounds) net explosive weight of most explosive substances. This provision was removed from the IMDG Code because it placed an inconsistent and unnecessary restriction on containers exceeding 6 m (20 foot) in length while placing no such restriction on smaller containers.

Sections 176.410 and 176.415. We are proposing to update these sections for consistency with international standards and with the prior removal of ammonium nitrate fertilizer proper shipping names from the HMR.

Part 178

Section 178.2. Paragraph (c)(1)(ii) would be revised by clarifying the information that the packaging manufacturer and each subsequent distributor are required to provide to packaging users.

Section 178.274. Based on a telephone call we received, in paragraph (j)(6), the size of the “NOT FOR RAIL TRANSPORT” marking would be revised from 20 cm (8 inches) to no less than 10 cm (4 inches) in height. We agree with the commenter's reasoning that 8 inches is excessive for portable tanks in that it could require a decal as long as 14 feet, 3 inches.

Section 178.705. We are proposing to correct the paragraph (c)(1)(iv)(A) wall thickness table for metal IBCs. During the typesetting process of the HM-215D final rule (66 FR 33316), published on June 21, 2001, the headings for the IBC types were misaligned, and we are proposing to correct them as presented in the HM-215D NPRM (65 FR 63294) published on October 23, 2000.

Section 178.812. In § 178.812(b)(1), we are proposing to add the words “with the load being evenly distributed,” consistent with the wording in § 178.812(b)(2). This text is necessary to clarify that the test must not be conducted with the load unequally applied to an individual lifting device.

Part 180

Section 180.350. We are amending § 180.350 by revising the section heading from “Applicability” to “Applicability and definitions” and by adding definitions for “Remanufactured IBCs,” “Repaired IBCs” and “Routine Maintenance of IBCs.”

Section 180.352. Two paragraphs would be revised and one new paragraph would be added. Paragraph (d)(1)(i) would be revised to specify that a repaired IBC must be retested and inspected in accordance with the applicable requirements in this section. Paragraph (f) would be revised to require that a record of such tests performed on repaired IBCs must be kept by the IBC owner or lessee. Finally, a new paragraph (d)(1)(iv) would be added to specify a requirement for marking repaired IBCs.

Section 180.605. Paragraph (k) would be revised to restore the inadvertently omitted inspection and test marking requirements for Specification DOT 51, 56, 57 and 60 portable tanks. The text, which was previously located in § 173.32, was omitted during the process of consolidating certain requirements and moving them to part 180 in the final rule, HM-215D, published June 21, 2001. For the height of the marking when displayed on the portable tank, we are also proposing to revise the “0.5 inches” conversion for 12 mm to “0.47” inches consistent with § 178.3.

IV. Rulemaking Analyses and Notices

A. Executive Order 12866 and DOT Regulatory Policies and Procedures

This proposed rule is not considered a significant regulatory action under section 3(f) of Executive Order 12866 and, therefore, was not reviewed by the Office of Management and Budget. This proposed rule is not considered a significant rule under the Regulatory Policies and Procedures of the Department of Transportation [44 FR 11034]. Benefits resulting from the adoption of the amendments in this proposed rule include enhanced transportation safety resulting from the consistency of domestic and international hazard communications and continued access to foreign markets by domestic shippers of hazardous materials. This proposed rule applies to offerors and carriers of hazardous materials, such as chemical manufacturers, chemical users and suppliers, packaging manufacturers, distributors, battery manufacturers, radiopharmaceutical companies, and training companies.

The majority of amendments in this proposed rule should result in cost savings and ease the regulatory compliance burden for shippers engaged in domestic and international commerce, including trans-border shipments within North America. For example, cost savings will be realized by shippers and carriers as a result of the following:

—Eliminating the differences between proper shipping names, UN number assignments and hazard classification, including subsidiary hazards, between the HMR and international regulations. As a result of these changes, shippers and carriers would not have to re-mark or repackage hazardous materials that are offered in both domestic and international transportation. Shipping papers would not need to be revised when shipping descriptions differ in domestic and international regulations.

—Providing certain exceptions including a placarding exception for sulfur and molten sulfur when the UN number is displayed on bulk packagings, and providing a packaging exception for large hard-cased robust lithium batteries.

We would authorize a delayed effective date and a one-year transition period to allow for training of employees and to ease any burden on entities affected by the amendments.

We recognize that there may be costs associated with the proposed § 172.202(a)(5) amendment requiring the type of packaging(s) to be entered on shipping papers. We believe that the proposed one-year transition period should minimize any costs; however, we are specifically requesting comments addressing the impact that the proposed amendment may have on businesses. Additionally, we are requesting suggestions to minimize any adverse impact, such as providing an extended transition period.

Many companies involved in domestic, as well as global operations, would realize economic benefits as a result of the adoption of amendments in this rulemaking. If the proposed changes are not adopted, U.S. companies will be at an economic disadvantage by being forced to comply with a dual system of regulations. The total net increase in costs to businesses in implementing this rulemaking is considered to be so minimal as to not warrant preparation of a regulatory impact analysis or regulatory evaluation.

B. Executive Order 13132

This proposed rule has been analyzed in accordance with the principles and criteria contained in Executive Order 13132 (“Federalism”). This proposed rule preempts State, local and Indian tribe requirements but does not propose any regulation that has substantial direct effects on the States, the relationship between the national government and the States, or the distribution of power and responsibilities among the various levels of government. Therefore, the consultation and funding requirements of Executive Order 13132 do not apply.

The Federal hazardous material transportation law, 49 U.S.C. 5101-5127, contains an express preemption provision (49 U.S.C. 5125(b)) that preempts State, local, and Indian tribe requirements on certain covered subjects. Covered subjects are:

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

(2) The packing, repacking, handling, labeling, marking, and placarding of hazardous materials;

(3) The preparation, execution, and use of shipping documents related to hazardous materials and requirements related to the number, contents, and placement of those documents;

(4) The written notification, recording, and reporting of the unintentional release in transportation of hazardous; or

(5) The design, manufacture, fabrication, marking, maintenance, recondition, repair, or testing of a packaging or container represented, marked, certified, or sold as qualified for use in transporting hazardous material.

This proposed rule addresses covered subject items (1), (2), (3), and (5) above and would preempt State, local, and Indian tribe requirements not meeting the “substantively the same” standard. This proposed rule is necessary to incorporate changes adopted in international standards, effective January 1, 2003. If the changes in this proposed rule are not adopted in the HMR, U.S. companies, including numerous small entities competing in foreign markets, would be at an economic disadvantage. These companies would be forced to comply with a dual system of regulations. The changes proposed 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. We propose that the effective date of Federal preemption be 90 days from the date of publication of a final rule in the Federal Register.

C. Executive Order 13175

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

D. Regulatory Flexibility Act

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

As discussed above, under Executive Order 12866, the majority of amendments in this proposed rule should result in cost savings and ease the regulatory compliance burden for shippers engaged in domestic and international commerce, including trans-border shipments within North America.

We recognize that there may be costs associated with the proposed § 172.202(a)(5) amendment requiring the type of packaging(s) to be entered on shipping papers. We believe that the proposed one-year transition period should allow sufficient time to train employees and to ease any burden on small entities affected by the amendments. We are specifically requesting comments addressing the impact that the proposed amendment may have on businesses, including suggestions to minimize any adverse impact, such as incorporating an extended transition period.

Many companies will realize economic benefits as a result of the proposed amendments. If the changes proposed in this NPRM are not adopted, U.S. companies, including small entities competing in foreign markets, will be forced to comply with a dual system of regulations to their economic disadvantage. Therefore, I certify that these proposed amendments will not, if promulgated, have a significant economic impact on a substantial number of small entities. This certification is subject to modification as a result of a review of comments received in response to this proposed rulemaking.

E. Paperwork Reduction Act

We submitted the information collection and recordkeeping requirements contained in this NPRM to the Office of Management and Budget (OMB) for approval under the provisions of the Paperwork Reduction Act of 1995, Section 1320.8(d). Title 5, Code of Federal Regulations requires us to provide interested members of the public and affected agencies an opportunity to comment on information collection and recordkeeping requests. Under the Paperwork Reduction Act, no person must comply with an information collection requirement unless it has been approved by OMB and displays a valid OMB control number.

Due to the new information collection requirement proposed in this NPRM for additional shipping paper documentation, we will be submitting a proposed new information collection to OMB for review and approval. This proposed new information collection, “Subsidiary Hazard Class & Number/ Type of Packagings”, would be assigned an OMB control number after review and approval by OMB. There would be an increase in information collection and recordkeeping burdens under this new information collection, OMB Control Number 2137-xxxx due to additional information, (e.g., subsidiary hazard class or division number and number and type of packagings) proposed to be included on shipping papers under this rule. RSPA currently has an approved information collection under OMB Control Number 2137-0557, “Approvals for Hazardous Materials” with 25,605 burden hours and $562,837.40. There would be only minor editorial revisions for section designations, etc., and no change in the burden for OMB Control Number 2137-0557 proposed under this rule. There would be only minor editorial revisions for section designations, etc., and no change in the burden for OMB Control Number 2137-0557 proposed under this rule.

We estimate that the new total information collection and recordkeeping burden resulting from the proposed additional information required on shipping papers would be:

“Subsidiary Hazard Class & Number/Type of Packagings” (New Information Collection) OMB No. 2137-xxxx

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 Year Annual Burden Hours: 45,705.

Total First Year Annual Start Up Cost: $1,115,992.

There are minor editorial changes proposed under this rule; however, there is no increase in burden for this information collection approval proposed under this rule. We estimate that the proposed 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.

Requests for a copy of this information collection should be directed to Deborah Boothe or Glenn Foster, Office of Hazardous Materials Standards (DHM-10), Research and Special Programs Administration, Room 8422, 400 Seventh Street, SW., Washington, DC 20590-0001, Telephone [phone]. Written comments should be addressed to the Dockets Unit identified in the Addresses section of this rulemaking. We should receive comments regarding information collection burdens prior to the close of the comment period identified in the DATES section of this rulemaking. We will publish a notice advising interested parties of the OMB control number for the new information collection when assigned by OMB.

F. 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.

G. 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 $100 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.

H. Environmental Assessment

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

(5) Except for empty packagings (see § 173.29 of this subchapter), cylinders for Class 2 materials and bulk packagings, the total quantity of hazardous materials covered by the description (by volume or mass, as appropriate) of each hazardous material bearing a different proper shipping name, UN number or packing group must be indicated together with the appropriate units of measurement (for example, 200 kgs). For Class 1 (explosive) materials, the quantity must be the net explosive mass. For shipments of packages in an overpack or transport unit (for example, freight container), this information must be provided for each hazardous material in each package within the overpack or transport unit. For hazardous materials transported in salvage packagings, an estimate of the quantity must be indicated. For cylinders for Class 2 materials and bulk packagings, indication of the total quantity must be shown (for example, “10 cylinders,” “2 IBCs,” or “1 cargo tank”). The number of packages and type of packages (for example, drum, box, jerrican, etc.) must also be indicated. Abbreviations may be used to specify the unit of measurement for the total quantity. Examples of descriptions of units of measure and the number and type of packagings include: “1 box, net mass, 30 kg” or “2 drums, gross mass, 200 kg.”

(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. For example, “Cyclobutyl chloroformate, 6.1, (8,3), UN2744, PGII.” Alternatively, the identification (ID) number may be listed first and the proper shipping name may be listed directly following the class and subsidiary risk. For example, “UN2744, 6.1, (8,3), Cyclobutyl chloroformate, PGII.”

Authority: 49 U.S.C. 5101-5127; 49 CFR 1.53.

65. Section 180.350 would be revised to read as follows:

§ 180.350

Applicability and definitions.

(a) This subpart prescribes requirements, in addition to those contained in parts 107, 171, 172, 173 and 178 of this subchapter, applicable to any person responsible for the continuing qualification, maintenance, or periodic retesting of an IBC. In addition, the following definitions apply:

(1) Remanufactured IBCs are metal, rigid plastic or composite IBCs produced as a UN type from a non-UN type, or are converted from one UN design type to another UN design type. Remanufactured IBCs are subject to the same requirements of this subchapter that apply to new IBCs of the same type (also see § 178.801(c)(1) of this subchapter for design type definition).

(2) Repaired IBCs are metal, rigid plastic or composite IBCs that, as a result of impact or for any other cause (such as corrosion, embrittlement or other evidence of reduced strength as compared to the design type), are restored so as to conform to the design type and to be able to withstand the design type tests. For the purposes of this subchapter, the replacement of the rigid inner receptacle of a composite IBC with a receptacle conforming to the original manufacturer's specification is considered repair. Routine maintenance of IBCs (see definition in paragraph (a)(3) of this section) is not considered repair. The bodies of rigid plastic IBCs and the inner receptacles of composite IBCs are not repairable.

(3) Routine maintenance of IBCs is the routine performance on metal, rigid plastic or composite IBCs of operations such as:

(i) Cleaning;
