I. Background
On December 21, 1990, RSPA (we) published a final rule (Docket HM-181; 55 FR 52402) based on the UN Recommendations, which comprehensively revised the Hazardous Materials Regulations (HMR), 49 CFR Parts 171 to 180, for harmonization with international standards. Since publication of the 1990 final rule we have issued five additional international harmonization final rules (Dockets HM-215A, 59 FR 67390; HM-215B, 62 FR 24690; HM-215C, 64 FR 10742; HM-215D, 66 FR 33316; and HM-215E, 68 FR 44992). The rules provided additional harmonization with international transportation requirements by more fully aligning the HMR with the corresponding biennial updates of the UN Recommendations, the IMDG Code and the ICAO Technical Instructions.
The UN Recommendations are not regulations, but rather are recommendations issued by the UN Committee of Experts on the Transport of Dangerous Goods (TDG) and on the Globally Harmonized System of Classification and Labeling (GHS). These recommendations are amended and updated biennially by the UN Committee of Experts. They serve as the basis for National, regional, and international modal regulations; specifically, the IMDG Code issued by the International Maritime Organization (IMO), and the ICAO Technical Instructions issued by the ICAO. In 49 CFR 171.12, the HMR authorize domestic transportation of hazardous materials shipments prepared in accordance with the IMDG Code if all or part of the transportation is by vessel, subject to certain conditions and limitations. In § 171.11, subject to certain conditions and limitations, the HMR authorize the offering, acceptance and transport of hazardous materials by aircraft, and by motor vehicle either before or after being transported by aircraft, provided the shipment is in accordance with the ICAO Technical Instructions.
The continually increasing amount of hazardous materials transported in international commerce warrants the harmonization of domestic and international requirements to the greatest extent possible. Harmonization serves to facilitate international transportation and at the same time ensures the safety of people, property and the environment. While the intent of the harmonization rulemakings is to align the HMR with international standards, we review and consider each amendment on its own merit. Each amendment is considered on the basis of the overall impact on transportation safety and the economic implications associated with its adoption into the HMR. Our goal is to harmonize without diminishing the level of safety currently provided by the HMR and without imposing undue burdens on the regulated public. In our efforts to continue to align the HMR with international requirements, this final rule incorporates changes into the HMR based on the Thirteenth Revised Edition of the UN Recommendations, Amendment 32 to the IMDG Code, and the 2005-2006 ICAO Technical Instructions, which become effective January 1, 2005. Petitions for rulemaking concerning harmonization with international standards and additional measures concerning facilitation of international transportation are also addressed in this final rule and serve as the basis of certain amendments. Other amendments are based on feedback from the regulated industry, other DOT modal administrations and our initiative. Also included are various editorial clarifications. Unless otherwise stated, the revisions are for harmonization with international standards.
II. Overview of Changes in This Final Rule
Amendments to the HMR in this final rule include, but are not limited to the following:
—Amendments to the Hazardous Materials Table (HMT) which add, revise or remove certain proper shipping names, hazard classes, packing groups, special provisions, packaging authorizations, bulk packaging requirements, passenger and cargo aircraft maximum quantity limitations and vessel stowage provisions.
—Amendments to the List of Marine Pollutants.
—Revisions and additions of special provisions.
—Removal of the air eligibility marking requirement.
—Addition of a “KEEP AWAY FROM HEAT” marking requirement for packages offered for transportation by air.
—Amendment to require that aerosols that are carried aboard an aircraft in accordance with § 175.10(a)(4) have their release devices protected by a cap or other suitable means.
—A grandfather provision to allow the shipment of materials classified as corrosive to steel or aluminum under ASTM G 31-72.
— A provision to require that the word “overpack” be marked on overpacks to indicate that inside packages comply with prescribed specifications.
—An amendment to the criteria for classification of materials that are corrosive to metals.
—Revision of the limited quantity provisions for Class 6.1, PG II materials and for materials with a subsidiary hazard of 6.1, PG II.
—Amendments to the packaging requirements for materials classified as Division 6.1, Packing Group I, Hazard Zone A or Hazard Zone B.
—Revision of the organic peroxide packaging requirements in order to have one consolidated packaging section for organic peroxides. The revised section will include three separate tables for organic peroxides authorized for transport in non-bulk packagings, IBCs, and bulk packagings other than IBCs, respectively. Additionally, the packaging tables will be updated through the amendments to the organic peroxide requirements that will add, revise, or delete certain entries in the organic peroxide tables.
III. Overview of Amendments Not Being Considered for Adoption in This Final Rule
This final rule makes changes to the HMR based on amendments to the Thirteenth Revised Edition of the UN Recommendations, Amendment 32 to the IMDG Code, and the 2005-2006 ICAO Technical Instructions, which become effective January 1, 2005. However, we are not adopting all of the amendments to those documents into the HMR. In many cases, amendments to the international regulation have not been adopted because of the framework or structure of the HMR. In several cases, we are handling certain amendments in separate rulemakings. For example, all amendments related to infectious substances are being handled under Docket HM-226A. In some instances, such as the amendment to ICAO Technical Instructions to allow certain oxygen generators aboard passenger carrying aircraft, we do not believe the amendment to be in the interest of public safety.
One of the goals of this rulemaking is to continue to maintain consistency between the HMR and the international requirements. We are not striving to make the HMR identical to the international regulations but rather striving to remove or avoid potential barriers to international transportation.
Below is a listing of those significant amendments to the international regulations that we have not included in this final rule with a brief explanation of why the amendment was not included:
• Requirements for infectious substances and genetically modified micro-organisms;
[Amendments to the HMR related to infectious substances will be addressed in a future rulemaking under Docket HM-226A. Several other federal agencies regulate genetically modified micro-organisms; thus we do not plan to adopt provisions for their transport in the HMR.]
• Compressed gas cylinders;
[Amendments to the HMR related to compressed gas cylinders will be addressed in a future rulemaking under Docket HM-220E.]
• Environmentally hazardous substances;
[Delay in action pending further amendments to the international regulations.]
• Hazardous materials security;
[Amendments to the HMR related to the UN Model Regulation's hazardous materials security requirements were promulgated in a rulemaking under the HM-232 Docket series.]
• Requirements for radioactive materials;
[Amendments to the HMR related to Class 7 (radioactive) materials are being addressed in a rulemaking under the HM-230 Docket series.]
• Non-specification bulk packagings;
[We are not adopting the new requirements in the UN Recommendations for non-specification bulk packagings including the additional inspection, testing and marking requirements. We are unsure about the cost impacts of imposing these additional amendments and, therefore, are not adopting any additional amendments at this time.]
• The reference to EN 10028-3, Part 3 for defining steel grain size relevant to the definition of fine grain steel;
[We do not believe there is a need to adopt the European standard EN 10028-3, Part 3 because this standard is equivalent to ASTM E 112-96 (IBR, see § 171.7 of this subchapter). In addition, the ASTM standard is currently referenced in the HMR and is more commonly used and recognized in the U.S.]
• Bulk authorization for UN0331, UN0332 and UN3375;
[For several years, we have authorized, under exemption, the transport of certain blasting agents in bulk packagings. We are currently reviewing those exemptions to determine if they should be included in the HMR. The amendments in the UN Recommendations related to the bulk authorizations for UN0331, UN0332 and UN3375 will be included in that review.]
• The removal of wooden barrel requirements;
[The removal of the wooden barrel requirements (2C1 and 2C2) may be considered in a future rulemaking.]
• The 24-hour gasket relaxation requirement;
[A requirement that removable head packagings for liquids not be drop tested until at least 24 hours after filling and closing to allow for any possible gasket relaxation was adopted in the thirteenth revised edition of the UN Model Regulations. We have conducted testing in coordination with drum manufacturers and have determined that this requirement is not substantiated by the results of the tests conducted. Therefore, we are not adopting into the HMR amendments relative to the 24-hour gasket relaxation requirement. We also opposed this requirement when it was considered by the UN TDG Sub-Committee.]
• Authorization to transport protective breathing equipment (PBE's) with an oxygen generator as cargo onboard a passenger-carrying aircraft.
[We do not believe that oxygen generators should be transported aboard passenger carrying aircraft. Therefore, we are not adopting the ICAO amendment that would allow oxygen generators in protective breathing equipment to be transported in passenger carrying aircraft.]
IV. Section-By-Section Review
Part 171
Section 171.7
Paragraph (a)(3) (incorporation by reference materials) is updated to include the most recent editions of the
ICAO Technical Instructions, the IMDG Code and the UN Recommendations. The updated editions of these standards become effective January 1, 2005. Additionally, the International Maritime Organization (IMO) recommends authorizing a one-year transition period, with a delayed compliance date of January 1, 2006, for the use of the updated edition (Amendment 32) of the IMDG Code.
The updated additions are as follows:
—The ICAO Technical Instructions, 2005-2006 Edition.
—The IMDG Code, Amendment 32.
—The UN Recommendations, Thirteenth Edition.
—The UN Manual of Tests and Criteria, 4th Revised Edition.
Paragraph (b) (list of informational materials not requiring incorporation by reference) is revised by adding an additional reference for a new method for determining the size of an emergency-relief device for portable tanks transporting organic peroxides. This revision is based on a petition for rulemaking numbered P-1428. The petition was submitted by the Organic Peroxides Producers Safety Division of the Society of the Plastics Industry, Inc.
One commenter recommended that we revise the “Note to Paragraph (h)(3)(vi)” in § 173.225 to maintain format consistency with the incorporation by reference entry for “Example of a Test Method for Venting Sizing: OPPSD/SPI Methodology” found in § 171.7(a). We disagree. The reference to a second example of a test method for venting sizing is not found in § 171.7(a) as a material incorporated by reference. Rather, it is found in § 171.7(b) as informational material not requiring incorporation by reference. Therefore, for clarification we are revising § 171.7(b) to include the reference to the
“American Institute of Chemical Engineers Process Safety Progress Journal.”
In addition, we are revising the “Note to Paragraph (h)(3)(vi)” in § 173.225 to include a reference to § 171.7(b),
list of informational materials not requiring incorporation by reference
.
Section 171.8
The definition for “salvage packaging” is revised to include the term “non-conforming.” The term “non-conforming” was added to the definition by the UN Committee of Experts in December 2000 to accommodate the use of salvage packaging for. Occasionally an undamaged package is found to be tested to a performance level which is less than that required for the specific substance it contains (
e.g.
, a drum tested to PG II standards containing a PG I substance). In other instances, the package is found to be a non-performance tested packaging containing a regulated substance. In these situations, it may not be safe or practical to transfer the material to the correct packaging to continue on to the consignee in order to ensure compliance with the HMR. Therefore, the use of salvage packaging to contain “non-conforming” packages will minimize the risk to those handling the package during its transport back to the shipper or to an appropriate disposal location.
Section 171.11
Paragraph (d)(15) is revised to clarify that the limitations therein also apply to oxygen generators contained in personal breathing equipment. In addition, paragraph (d)(17) is revised to indicate that an organic peroxide that is not identified by a technical name in any of the organic peroxide tables found in § 173.225 must be approved by the Associate Administrator in accordance with the requirements of § 173.128(d).
Section 171.12
In § 171.12, paragraph (b)(20) is revised to indicate that an organic peroxide that is not identified by a technical name in any of the organic peroxide tables found in § 173.225 must be approved by the Associate Administrator in accordance with the requirements of § 173.128(d).
Section 171.12a
Paragraph (a) is revised to clarify the requirements for the return to Canada of bulk packagings that correspond to DOT or UN Specifications. Paragraph (b)(9)(ii) is revised to indicate that the shipping certification must be completed for shipments from Canada that enter the U.S. Paragraph (b)(18) is revised to indicate that an organic peroxide that is not identified by a technical name in any of the organic peroxide tables found in § 173.22 must be approved by the Associate Administrator in accordance with the requirements of § 173.128(d).
Section 171.14
Paragraphs (d) and (d)(1) are revised to authorize a delayed implementation date for the amendments in this final rule. The effective date of this final rule is January 1, 2005. We are also, authorizing a delayed compliance date of January 1, 2006, which is comparable to the transitional provisions provided in the final rule published under Docket HM-215E. The delayed mandatory compliance date offers sufficient time to implement the new requirements.
Paragraph (d)(2) is revised to authorize certain intermixing of old and new requirements.
Part 172
Section 172.101
The regulatory text preceding the Hazardous Materials Table is revised as follows:
Paragraph (c)(11) and the corresponding note to paragraph (c)(11) are amended to revise a section reference. The reference to § 173.225(c) in the first sentence is revised to read § 173.225(b) and the reference to § 173.225(c)(2) in the note to paragraph (c)(11) is revised to read § 173.225(b)(2).
Paragraph (d)(4) is revised by adding a statement indicating that when the abbreviation “Comb liq.” is found in the “Hazard class or division” column of the Hazardous Materials Table (column 3), the material falls into the “Combustible liquid” hazard class.
Paragraph (i)(3) of this section is revised to specify that Column 7 of the Hazardous Materials Table contains additional bulk packaging authorizations and limitations for the use of UN portable tanks.
§ 172.101 The Hazardous Materials Table (HMT).
In this final rule we made various amendments to the HMT. Readers should review all changes for a complete understanding of the Table amendments. The HMT has been reprinted in its entirety due to the numerous changes. Under this final rule the changes to the HMT for the purpose of harmonizing with international standards, unless otherwise stated, include, but are not limited to the following:

A commenter stated that by adding the shipping names for desensitized explosives under identification numbers UN3379 and UN3380, approvals should be modified to authorize the use of classifications for the applicable hazardous materials. The commenter also noted that due to these additions, the definitions for flammable solids and flammable liquids require revision to account for the new shipping names. We do not anticipate a significant number of explosives being assigned to these shipping names. Therefore, we disagree with the commenter's contention that each holder of an EX number request an updated shipping classification. In addition, we do not agree with the commenter's request to revise the definitions of flammable solid and flammable liquid to include the additional proper shipping names. The definitions of flammable solid and flammable liquid adequately describe materials assigned to those shipping names. Additionally, shipping names are not found under hazard class definitions, but rather, in the HMT.
• We added the following new generic entries for materials that are toxic by inhalation. These new names will replace the existing generic entries in the HMT. This action is consistent with the addition of proper shipping names that were incorporated into the Thirteenth Revised Edition of the UN Recommendations. Affected entries are as follows:
UN3381 Toxic by inhalation liquid, n.o.s.
with an inhalation toxicity lower than or equal to 200 ml/m
3
and saturated vapor concentration greater than or equal to 500 LC
50
.
UN3382 Toxic by inhalation liquid, n.o.s.
with an inhalation toxicity lower than or equal to 1000 ml/m
3
and saturated vapor concentration greater than or equal to 10 LC
50
.

• We added the following new generic entries for organometallic substances. This action is consistent with the addition of proper shipping names that were incorporated into the Thirteenth Revised Edition of the UN Recommendations. The new entries are as follows:
UN3391 Organometallic substance, solid, pyrophoric
UN3392 Organometallic substance, liquid, pyrophoric
UN3393 Organometallic substance, solid, pyrophoric, water-reactive
UN3394 Organometallic substance, liquid, pyrophoric, water-reactive
UN3395 Organometallic substance, solid, water-reactive
UN3396 Organometallic substance, solid, water-reactive, flammable
UN3397 Organometallic substance, solid, water-reactive, self-heating
UN3398 Organometallic substance, liquid, water-reactive
UN3399 Organometallic substance, liquid, water-reactive, flammable
UN3400 Organometallic substance, solid, self-heating
In addition, we are continuing to allow the use of the following specific Organometallic entries: UN1366, UN1370, UN2005, UN2445, UN3051, UN3052, UN3053, and UN3076. However, we anticipate removing these entries from the HMT by January 1, 2007.
• The U.N. Recommendations have adopted a rationalized approach for the assignment of UN portable tank instructions for solid materials. Based on that rationalized approach, we made several changes to UN portable tank authorizations in the HMR. These changes are summarized as follows. For a more specific identification of the affected shipping descriptions, refer to the
UN report
located in the public Docket.
For Division 4.1, Packing Group I materials, the use of UN portable tanks is not authorized.
For Division 4.3 materials with a subsidiary class of 6.1, in Packing Group I, the use of portable tanks is not authorized.
For materials of Divisions 4.1, 4.2, 4.3, 5.1, 6.1, and Classes 8 and 9, in Packing Group II, Special Provisions T3 is specified.
For Division 4.2, Packing Group I materials, T21 and TP7 is specified.
For Division 4.3, Packing Group I materials, T9 and TP7 is specified.
For Division 5.1, Packing Group I materials, the use of UN portable tanks is not authorized.
For Division 6.1 and Class 8, Packing Group I materials, T6 is specified.
For materials of Divisions 4.1, 4.2, 4.3, 5.1, 6.1, and Classes 8 and 9, in Packing Group III, Special Provisions T1 is specified.
• Several entries in the HMT have been revised by amending column 9B to read “forbidden” so that the materials are no longer authorized for transport aboard cargo aircraft. The entries have been revised because they meet the criteria of either Zone C or Zone D inhalation toxicity. All other Zone C and Zone D toxic by inhalation materials listed in the HMR are currently already forbidden from transport aboard passenger and cargo aircraft (these materials are already forbidden from transport aboard passenger aircraft). The entries to be revised include:
Zone C
UN2204 Carbonyl sulfide
UN1023 Coal gas, compressed
UN1064 Methyl mercaptan
UN1048 Hydrogen bromide, anhydrous
UN1079 Sulfur dioxide
Zone D
UN1005 Ammonia, anhydrous
UN3318 Ammonia solution,
relative density less than 0.880 at 15 degrees C in water, with more than 50 percent ammonia
UN1040 Ethylene oxide
or
Ethylene oxide with nitrogen
up to a total pressure of 1MPa (10 bar) at 50 degrees C
UN1040 Ethylene oxide
or
Ethylene oxide with nitrogen
up to a total pressure of 1MPa (10 bar) at 50 degrees C
UN2191 Sulfuryl fluoride
Also, see § 172.102 for additional HMT amendments.
Appendix B to § 172.101
In Appendix B to § 172.101, List of Marine Pollutants, we removed the entries “Diphenyl oxide and biphenyl phenyl ether mixtures,” “Isoamyl mercaptan,” “Pentanethiols,” and “Tetrachlorophenol.” We revised the entry “2, 6-Di-tert-Butylphenol” and we added the entry “Chloropicrin.”
Section 172.102
We amended § 172.102, Special Provisions, as follows:
• Several entries in the HMT are revised by adding special provisions A3, A6, A7, A9, A10, N3, and N36 to align this section with the equivalent special provisions in the ICAO Technical Instructions (13, 2, 5, 4, 7, 21, and 3 respectively).

• Paragraph (b)(3) of this section is amended to specify that a “B” code refers to a special provision that applies only to certain bulk packaging requirements and that, unless otherwise stated, does not apply to UN, IM Specification portable tanks or IBCs.
• Paragraph (b)(4) of this section is amended to specify that a code containing the letters “IB” or “IP” refers to a special provision that applies only to transportation in IBCs.
• Paragraph (b)(7) of this section is amended to specify that a code containing the letter “T” refers to a special provision which applies only to transportation in UN or IM Specification portable tanks.
• Paragraph (b)(8) is redesignated (b)(9) and a new paragraph (b)(8) is added to specify that a code containing the letters “TP” refers to a special provision that is in addition to those provided by the portable tank instructions or the requirements in part 178.
• Special Provision 47 is revised to include an additional exception currently in the UN Model Regulations specifying that a leakproofness test is not required when the liquids are fully absorbed in solid material contained in sealed bags.
• Special Provision 135 is revised to expand the applicability of the proper shipping names “Vehicle, flammable liquid powered” and “Vehicle, flammable gas powered” to include hybrid electric vehicles.
• Special Provision 137 is revised to expand the exception for “Cotton, dry”.
• Special Provision 143 is removed and relocated to § 173.219 so that the limitations on the types of hazardous materials authorized apply to both self-inflating and non-self-inflating life-saving appliances.
• Special Provision 153 is relocated to new paragraph (k) in § 173.115 and revised to include amended classification criteria for aerosols containing flammable constituents consistent with criteria in the UN Model Regulations. The revised criteria include methods for the classification of aerosols based on the percentage of flammable components. One commenter agreed with the removal of Special Provision 153 and the relocation of classification criteria for aerosols to § 173.115(k).
• New Special Provision 163 is added to specify that Ammonium Nitrate Emulsions are required to satisfactorily pass Test Series 8 of the UN Manual of Tests and Criteria, Part I, Section 18.
• New Special Provision 164 is added to specify that an approval is required for “Desensitized explosives, liquid, n.o.s.” and “Desensitized explosives, solid, n.o.s.”
• New Special Provision 165 is added to the calcium hypochlorite PG II and the PG III entries for UN1748 and UN2880 to specify the danger of exothermic decomposition and require shading from direct sunlight and sources of heat during transportation. One commenter agreed with our efforts to harmonize the HMR with UN Recommendations, but was concerned with the intent of Special Provision 165. This commenter agreed that calcium hypochlorite should be shaded from direct sunlight but questioned the ambient heat and ventilation provisions. The commenter stated that calcium hypochlorite is currently transported in closed cargo transport units, thus, satisfying the requirement to protect this hazardous material from direct sunlight. However, since the cargo transport units are not ventilated by fan or induced ventilation, and the cargo transport units would be subjected to ambient heat, a violation of Special Provision 165 appears imminent. We disagree. We feel Special Provision 165 provides latitude for compliance with the ventilation and ambient heat requirements. Proper ventilation and protection from ambient heat can be achieved during the loading process of the cargo transport units and throughout the transportation cycle by allowing adequate space for air movement around the calcium hypochlorite packages. We do agree; however, that cargo transport units themselves should not be required to be shaded from direct sunlight. Therefore, we have revised the regulatory text accordingly.
• New Special Provision 166 is added to the PG II entry for calcium hypochlorite, UN2880 and UN1748 to indicate that calcium hypochlorite in the non-friable tablet form may be transported as a PG III material.
• New Special Provision 167 is added to the new entry for “Hydrogen in a metal hydride storage system” to specify that such storage systems shall always be considered as containing hydrogen.
• New Special Provision 170 is added to Organometallic substances entries (UN3391, UN3392, UN3393, and UN3394). The special provision requires air to be eliminated from the vapor space by nitrogen or other means.
• New Special Provision 171 is added to the UN2880 PG III entry. Since UN2880 also covers mixtures of hydrated calcium hypochlorite in any concentration, some formulations in other than tablet form (
e.g.
, in granular form) may meet the criteria for classification in Division 5.1, Packing Group III when subjected to the relevant test in the UN Manual of Tests and Criteria. The PG III entry for calcium hypochlorite is only authorized when the material is offered in the non-friable tablet form or for granular or powdered
mixtures. This entry is not authorized for the pure form of “Calcium hypochlorite, hydrated”. We also recognize that some formulations, when tested, do not meet the criteria for classification in Division 5.1. In light of this, we added a new Special Provision 171 to the UN2880, PG III entry in the HMT to allow for the possibility to classify powdered or granular mixtures of hydrated calcium hypochlorite in Packing Group III when data indicate that the mixture meets the criteria for assignment to PG III. One commenter supports the revisions that align calcium hypochlorite entries in the HMT with UN Recommendations. However, this commenter requested the addition of Special Provision 171 to the entry, “Calcium hypochlorite, dry or Calcium hypochlorite mixtures dry, (UN1748)” for consistent alignment with the UN Recommendations. We agree. After further review of the UN Recommendations, we have determined that the UN Special Provision 316 is equivalent to the proposed Special Provision 171 in Docket HM-215G, and is applicable to both the “dry” and “hydrated” calcium hypochlorite entries. Therefore, we are assigning Special Provision 171 to the “Calcium hypochlorite, dry
or
Calcium hypochlorite mixtures dry, (UN1748)” entry.
• Special Provision A11 is currently assigned to UN 2983, Ethylene oxide and Propylene oxide mixtures and UN 1411, Lithium aluminum hydride, ethereal. In the ICAO Technical Instructions these substances are only authorized for transport in metal cylinders. A11 states “For combination packagings, when metal inner packagings are permitted, only specification cylinders constructed of metals which are compatible with the hazardous material may be used. In the NPRM, we proposed to harmonize with the applicable ICAO Technical Instruction particular packing requirement (PPR 8), however discussions with the ICAO Dangerous Goods Panel and further analysis of ICAO PPR 8 has revealed that the requirement may need to be amended. Our analysis showed that other packagings, including glass inner packagings, are authorized, and as such restricting packagings to only specification cylinders appears unnecessarily restrictive. As such we are not proposing to amend Special Provision A11 in this final rule.
• Consistent with ICAO, we are adding a proper shipping name to the HMT for “Receptacles, small containing gas, 2.2 with a subsidiary of 5.1.” A new “A” code (A14) is added to prohibit this material from being transported as a limited quantity or consumer commodity in accordance with § 173.306 aboard an aircraft. This new “A” code has also been added to the following additional shipping names: “Oxygen, compressed,” Carbon dioxide and oxygen mixtures,” “Nitrous oxide”, “Compressed gas oxidizing,” and “Liquefied gas, oxidizing.”
• For consistency, the authorization in Special Provision B69 to allow dry sodium or potassium cyanide in siftproof, water-resistant fiberboard IBCs is relocated to new Special Provision IP20.
• Paragraph (c)(4) of this section is amended by relocating “Table 2.—Organic Peroxide IBC Code (IB52)” to paragraph (e) of § 173.225 and renaming it the “Organic Peroxide IBC Table.” Table 3.—IP Codes is redesignated Table 2.—IP Codes. The wording of paragraph (c)(4) is revised to indicate that Table 3.—IP Codes had been redesignated Table 2.—IP Codes. All references to IB52 in the HMR are removed and replaced with “Organic Peroxide IBC Table” or “§ 173.225(e),” as applicable.
• Paragraph (c)(7) is amended by relocating the Portable Tank Code T50 Table to § 173.313 and renaming it “UN Portable Tank Table for Liquefied Compressed Gases.” The T50 Table and its description is removed from paragraph (c)(7)(iv) and replaced with a statement indicating that the new “UN Portable Tank Table for Liquefied Compressed Gases” is found in § 173.313. All references to T50 in the HMR are removed and replaced with “UN Portable Tank Table for Liquefied Compressed Gases in § 173.313.” In addition, paragraph (c)(7) is amended by relocating Portable Tank Code T23 to paragraph (g) of § 173.225 and renaming it the “Organic Peroxide Portable Tank Table.” Portable Tank Code T23 and its description found in paragraph (c)(7)(iii) are removed and paragraphs (c)(7)(iv)-(c)(7)(vii) are redesignated (c)(7)(iii)-(c)(7)(vi), respectively. All references to T23 in the HMR are removed and replaced with “Organic Peroxide Portable Tank Table” or “§ 173.225(g),” as applicable.
• New paragraph (c)(8) is added to provide an introduction to the “TP” codes (
i.e.
, portable tank special provisions). The existing paragraph (c)(8) is redesignated paragraph (c)(9).
• New Special IBC Packing Provision IP13 is added to specify that transportation by vessel in IBCs is prohibited.
• New Special IBC Packing Provision IP14 is added to specify that air must be eliminated from the vapor space by nitrogen purging or other means.
• New Special IBC Packing Provision IP20 is added to specify that dry sodium cyanide and potassium cyanide are also permitted in siftproof, water-resistant, fiberboard IBCs when transported in closed freight containers or transport vehicles.
• Portable tank Special Provision TP3 is revised to include the maximum degree of filling (in %) for solids transported above their melting points.
• Special Provision TP6 is revised by removing the word “event” and replacing it with the word “incident.”
• Portable tank Special Provision TP9 is removed from column (7) of the HMT for all materials that reference a T code special provision. Special provision TP9 states that a material with TP9 in Column (7) may only be transported in a portable tank if approved by the Associate Administrator. A material that has been given a T code does not require approval and is not subject to Special Provision TP9.
• In the NPRM we proposed adoption of a new portable tank special provision, TP33, by adding the new provision to certain entries in the HMT. However, we neglected to include the text of the provision itself. We are correcting this omission in this final rule.
Section 172.202
We are editorially revising paragraph (a)(2)(iii) by removing the examples that illustrate the optional provision to enter primary and subsidiary hazard class or division names on shipping papers for domestic shipments. In the HM-215E response to appeals final rule (69 FR 34604) that was published on June 22, 2004, we reinstated the provision which was removed in a previous rulemaking (68 FR 44992). During the process of correcting a printing error in one of the examples, we determined that the regulatory text is complete and sufficient without the use of examples.
In the NPRM [69 FR 34741] we proposed to amend paragraph (a)(5)(i) to require the quantity shown on a shipping paper for an explosive article, such as Cartridges, small arms, to be the net mass of the entire article rather than the net mass of the explosive contained in the article. Commenters generally support the proposal, suggesting that it will provide for consistency across modes of transportation and for more accurate calculations. However, several of these commenters note that, for certain explosive articles that contain very small amounts of an explosive, showing the net mass of the article rather than of the explosive contained in the article could misrepresent the transportation risk associated with the article. Two commenters state that,
because shippers have historically calculated the net mass based on the actual explosive material contained in the article rather than the entire article, the clarification proposed in the NPRM could cause increased confusion for shippers.
Internationally, as well, there is some concern that, at least for large explosive articles, the quantity indicated on the shipping paper should be the net mass of the explosive substances contained in the article rather than the net mass of the article itself. As suggested by some commenters to the NPRM, a number of the members of UN Transport of Dangerous Goods Sub-Committee agree using the net mass of the entire article rather than the net mass of the explosive material contained in the article may not appropriately communicate the explosive hazard to emergency responders. Until this issue is resolved through a change to the UN Model Recommendations, we are, in this final rule, amending paragraph (a)(5)(i) to clarify that for explosive articles the quantity shown on a shipping paper may be expressed in terms of the net mass of the article or the net mass of the explosive substances contained in the article. It should be noted, however, that for purposes of determining the per-package quantity limitations shown in Column 9 of the HMT, § 172.101(j)(3) specifies that when articles or devices are specifically listed by name, the net quantity limitation applies to the entire article or device rather than to its hazardous components. This would include explosive articles listed by name in the HMT. For example, in the case of a listed explosive article weighing 15 kg and containing 500 grams of explosive substance, the weight shown on the shipping paper may be 500 grams or 15 kg, but the weight used for purposes of compliance with Column (9) of the HMT must be 15 kg as required by § 172.101(j)(3).
Particularly for large articles, the quantity indicated on the shipping paper should be the net mass of the explosive substances contained in the article. For small explosive articles, such as Cartridges, small arms, we believe that the net mass of the article can be used to satisfy the total quantity requirement in § 172.202(a)(5)(i). As a practical matter, it is easier, and in certain instances necessary, for an offeror to provide the net mass of the article and the net explosive mass. For example, as previously stated, the net mass of an article must be used to ensure compliance with the per package quantity limitations set forth in Column 9 of the § 172.101 Hazardous Materials Table for transport aboard aircraft or passenger rail (see § 172.101(j)(3)). However, for operational purposes, such as for stowage and segregation of large quantities of explosives or determining the quantity of explosives that can be transported on a vessel [see § 176.142(b)], the net explosive mass of the explosive substances contained in articles is needed.
Section 172.203
Paragraph (f) is revised by including the passenger and cargo aircraft limitation certification statement that is found in § 172.204. This aligns the HMR with the ICAO TI (see 4.1.5.8.1(b) of the ICAO TI). A new paragraph (i)(3) is added to specify additional shipping paper description requirements for a hazardous material consigned under an “n.o.s.” entry when offered for transportation by vessel. In addition, paragraph (m)(2) is revised to specify that the phrase “Poison Inhalation Hazard” or “Toxic Inhalation Hazard” is not required to be repeated if it otherwise appears in the shipping description. Finally, in paragraph (o)(3), the reference to § 173.225(c)(2) is amended to read § 173.225(b)(2).
One commenter felt the requirement to add a segregation code on the shipping paper for “n.o.s.” entries is unnecessary and unduly burdensome. In addition, the commenter is concerned that there may not be sufficient space on the shipping paper to indicate this notation. If, however, this requirement is adopted, the commenter requested an example of the required entry on shipping papers. We disagree. We do not feel this additional requirement is unnecessary or overly burdensome. The additional shipping paper description requirements apply only to hazardous material consigned under an “n.o.s.” entry when offered for transportation by vessel. We believe that consignors should be familiar with the hazards and segregation risks of their shipments, specifically “n.o.s.” materials that are not assigned segregation groups. By indicating the need to segregate such materials on the shipping paper, the consignor increases the likelihood that appropriate stowage procedures are followed, ensuring the safety of the vessel and its cargo. We also do not agree that there is inadequate space available on shipping papers to include the segregation group. However, we do agree that an example of the required entry should be presented for clarity and uniformity. Therefore, as recommended by the commenter, we are adding the example “IMDG Code segregation group—1 Acids” to § 172.203.
Section 172.204 and Section 172.321—Air Eligibility Marking
Under HM-215E (68 FR 44992), the air eligibility marking was adopted into the HMR as new § 172.321. Since publication of that final rule, the ICAO's Dangerous Goods Panel removed the air eligibility marking requirement from the ICAO Technical Instructions. In lieu of this marking, ICAO adopted a requirement that the shipping paper certification statement include the statement “I declare that all of the applicable air transport requirements have been met” when a hazardous material is offered for air transportation. Additionally, the revised section provided examples of the applicable air transport requirements that must be met. Based on this action, we revised the air eligibility marking requirement by making it optional rather than mandatory and adding the additional shipping paper certification statement for shipments going by aircraft. Therefore, we revised § 172.204(c)(3) by requiring that the statement “I declare that all of the applicable air transport requirements have been met” be included on the shipping paper in addition to the current certification statement when a hazardous material is offered for air transportation. Additionally, the revised section provides examples of the applicable air transport requirements that must be met and various section references. In order to allow shippers to expend stocks of preprinted shipping papers containing the previous certification statement, we are providing an additional ten month transitional provision for the new certification statement. Two commenters support RSPA's decision requiring shippers to sign the certification declaring compliance with requirements for air transportation. Additionally, several commenters agree with the revision to make the air eligibility marking optional. However, some commenters suggest making the marking “permissible” instead of “optional” to avoid potential confusion. We disagree. We are removing the requirement for shippers to mark packages acceptable for air transport with the air eligibility marking. This revision does not prohibit the use of the marking.
Section 172.315
Section 172.315 is amended to ensure that packages containing limited quantities which are transported by air are marked with the proper shipping name. Although the amendment was not proposed in this rulemaking, it was previously proposed and adopted under
HM-215E (68 FR 45000) but was omitted due to an editorial error during publication. The amendment provides harmonization with the ICAO Technical Instructions, which do not allow the UN number within a square-on-point border as a substitute for the proper shipping name. Note that this amendment does not preclude the ID number/square-on-point border from appearing on a package transported by air, it simply ensures that the proper shipping name is also required.
Section 172.317
A new § 172.317 is added to require a “KEEP AWAY FROM HEAT” handling mark on packages containing self-reactive substances of Division 4.1 or organic peroxides of Division 5.2 when such packages are transported by air.
Part 173
Section 173.3
The NPRM proposed to revise the requirements for use of salvage drums to include packages of hazardous materials that are found not to conform with the requirements of the HMR. In addition, the NPRM proposed to clarify that salvage drums may only be used for damaged, defective, non-conforming, or leaking packages identified as such after the packages have been placed in transportation. One commenter suggests that the phrase “after having been placed in transportation” as used in the NPRM is confusing and requests that we clarify the phrase using the terms “pre-transportation functions” and “transportation functions” as defined in a final rule published under Docket HM-223 October 30, 2003 (68 FR 61905). In response to this comment, in this final rule, we modified § 173.3(c) to clarify that salvage drums are to be used for damaged, defective, non-conforming, or leaking packages identified during transportation as “transportation” is defined in § 5102(12) of Federal hazardous materials transportation law—that is, the movement of property and loading, unloading, or storage incidental to the movement. When the HM-223 final rule becomes effective, the statutory definition for “transportation” will be added to § 171.8 of the HMR, as will definitions for “movement,” “loading incidental to movement,” “unloading incidental to movement,” and “storage incidental to movement.” Note that a package found to be leaking prior to its being placed in transportation may not be packaged in a salvage drum. Instead, it must be repackaged into an authorized packaging in accordance with applicable HMR requirements.
Section 173.24
For consistency with the UN Recommendations, paragraphs (g)(4) and (g)(5) are revised to clarify the following:
(A) That IBCs (subject to the requirements in § 173.24(g)) are permitted to be vented to reduce internal pressure; and
(B) That venting of IBCs is not conditional upon whether a bulk special provision is indicated for a particular hazardous material in the § 172.101 hazardous materials table.
In addition, paragraph (i) is revised to clarify that other general requirements specific to air transportation apply and are found in § 173.27.
Section 173.25
Paragraph (a)(2) is revised by removing the requirement to mark an overpack with the air eligibility marking. In addition, in paragraph (a)(4), we are amending the HMR to require overpacks to be marked with the word “OVERPACK” or, alternatively, until October 1, 2007, with a statement indicating that inside packages comply with prescribed specifications. This is in response to adoption by the United Nations of the “OVERPACK” marking to indicate that packages within an overpack comply with prescribed specifications when specification markings on inside packagings within the overpack are not visible.
Section 173.27
Paragraph (i) is revised to indicate that the air eligibility mark has been removed. This section references a new requirement for shippers to place the following statement at the end of the certification statement when a hazardous material is authorized for air transportation: “I declare that all applicable air transport requirements have been met.”
Section 173.28
In paragraph (c)(2), we deleted the words “or a UN 1H1 plastic drum” in order to harmonize the HMR with the UN Model Regulations and remove a source of confusion within the regulated community regarding the reconditioning of a non-bulk packaging.
Section 173.115
In § 173.115, a new paragraph (k) is added (see discussion under § 172.102, Special Provision 153). One commenter noted that the proposed new § 173.115(k) would not allow aerosols to contain corrosive substances of Packing Group II. The commenter further noted that UN Special Provision 63 allows aerosols to contain corrosive substances of Packing Group II and requested we harmonize with the UN Special Provision 63 in this regard. We agree with the commenter and further note that currently, the HMR authorizes a proper shipping name of “Aerosols, corrosive Packing Group II or III, each not exceeding 1 L capacity”. We are amending § 173.115(k) accordingly to clarify that aerosols may contain corrosive substances of Packing Group II.
Section 173.120 and Appendix H to Part 173
A commenter noted that under section § 173.120(a)(3), the reference to Appendix H for sustained combustibility tests directs the reader to Figures 5.1 and 5.2 found in the UN Recommendations. These figures are no longer in the UN Recommendations, but, rather, are located in section 32.5.2 of the Fourth Revised Edition of the UN Manual of Tests and Criteria. We agree with the commenter. Therefore, we are amending Appendix H to Part 173 to reference the UN Manual of Tests and Criteria.
Section 173.128
In paragraph (d)(1)(i), the section reference is revised to read § 173.225(c). In addition, in paragraphs (d)(1)(ii) and (d)(1)(iii), the section reference is revised to read § 173.225(b).
Section 173.132
In paragraph (b)(1), we revised the definition of LD
50
for acute oral toxicity to indicate that adult albino rats may be tested without regard to gender. The current definition for LD
50
for acute oral toxicity in § 173.132(b)(1) is based on the Organization for Economic Co-Operation and Development (OECD) Test Guideline (TG) 401. The OECD has agreed to three test methods that will replace the current TG 401. The United Kingdom, Germany and the United States of America took the lead in the development of the three alternative tests that OECD has now adopted and published in the OECD Guidelines for the Testing of Chemicals. In a continuing attempt to improve the estimate of acute oral toxicity while reducing the number of animals used per test, three alternative TGs have been developed and implemented to replace TG 401. The three TGs are the Fixed Dose Procedure (FDP, TG 420), the Acute Toxic Class Method (ATCM, TG 423), and the Up-and-Down Procedure (UDP, TG 425). The text is consistent
with the text in the 13th revised edition of the UN Model Regulations.
Section 173.136
We added a new paragraph (d) to provide a grandfather clause that will allow for the continued shipment of materials classified as corrosive to steel or aluminum under ASTM G 31-72 without retesting.
Section 173.137
In paragraph (c)(2), we propose to eliminate the references to ASTM G 31-72 as an acceptable test description and add a statement indicating an acceptable test is prescribed in the Manual of Tests and Criteria, Part III, Section 37.
Sections 173.150, 173.151, 173.152, 173.153 and 173.154
We are allowing most Division 6.1, Packing Group II materials to be transported under the limited quantity provisions when the packagings contain not more than 100 mL (3.38 ounces) each for liquids or 0.5 kg (1.1 pounds) each for solids. However, consistent with the limited quantity authorization for Division 6.1, Packing Group III, we are not providing a labeling exception for these materials. We are also not allowing these materials to be shipped as consumer commodities. In addition, we revised the limited quantity sections for the other hazard classes of materials to take into account materials with a subsidiary hazard of 6.1 Packing Group II. One commenter agreed with the amendment allowing numerous Class 3, PG II materials with Class 8 and other subsidiary hazards to be transported as limited quantities.
Section 173.185
In § 173.185, we amended paragraphs (c)(3) and (e)(6), to require those lithium cell and battery design types that are required to be subjected to the UN performance tests to be of a type that is proven to meet the requirements of the performance tests specified in the UN Manual of Tests and Criteria, Fourth Revised Edition. These cells and batteries are currently required to be of a type that is proven to meet the tests in the third revised edition. We also proposed a grandfather provision that would authorize a lithium cell or battery that was transported prior to the effective date of this rule that is of a type proven to meet the UN performance tests in the third revised edition to not be required to be retested in accordance with the tests in the fourth revised edition. One commenter supported this approach and stated that it is both necessary and appropriate to allow continued transport of cells and batteries tested and qualified under the UN lithium battery design qualification tests in accordance with the UN Manual of Tests and Criteria, Third Revised Edition. The commenter further stated that providing a grandfather provision for previously tested cells and batteries would avoid the need and expense of requalifying these cells and batteries in accordance with the new tests prescribed in the Fourth Revised Edition of the UN Manual of Tests and Criteria. After further consideration, we believe that authorizing an indefinite period for the transport of batteries that were tested in accordance with the UN Manual of Tests and Criteria, Third Revised Edition, 1999 may not be in the best interest of safety. The tests in the UN Manual of Tests and Criteria, Fourth Revised Edition provide a slightly higher level of safety and we believe that further consideration needs to be taken in considering whether at some point in time all applicable lithium batteries and cell design types should be proven to meet the requirements of the UN Manual of Tests and Criteria, Fourth Revised Edition. As a result, we will issue a proposal shortly specifically to address the full unrestricted adoption of the Fourth Revised Edition of the UN Manual of Tests and Criteria.
Section 173.186
In § 173.186, in paragraph (e), we amended the gross weight for UN 4G outer packages authorized for the transportation of strike-anywhere matches, to be consistent with the UN Model Regulations by increasing the weight from 27 kg (60 pounds) to 30 kg (66 pounds).
Section 173.187
We revised § 173.187 to authorize certain solid hazardous materials to be transported in DOT specification cylinders other than Specification 8 and 3HT cylinders. This change eliminates the need for DOT Exemption “DOT-E 11548.”
Sections 173.211, 173.212, and 173.213
We revised these sections to authorize certain solid hazardous materials to be transported in DOT specification cylinders other than Specification 8 and 3HT cylinders. This change removed the need for DOT Exemption “DOT-E 11548.”
Section 173.219
We revised § 173.219 for consistency with the UN Model Regulations and the ICAO Technical Instructions. Included in the revision is an allowance for self-inflating life-saving appliances to contain cartridges, power devices of Division 1.4S, for purposes of the self-inflating mechanism. In addition, we provided an exception from regulation for life-saving appliances containing only carbon dioxide cylinders not exceeding 100 cm
3
capacity, provided they are overpacked in rigid outer packagings with a maximum gross mass of 40 kg. Finally, the limitations currently found in Special Provision 143 are relocated to § 173.219 (see preamble discussion under Special Provision 143).
Section 173.220
Paragraph (b)(2) is amended to harmonize the requirements for transporting flammable gas powered vehicles by air with the requirements of Packing Instruction 900 of the ICAO Technical Instructions.
Section 173.224
Paragraph (b)(4) of this section is amended to include the new references for § 173.225. The section reference to § 173.225(e) for the authorization of bulk packagings is replaced with § 173.225(f) for IBCs and § 173.225(h) for other bulk packagings.
Section 173.225
This section is amended to update the Organic Peroxide Table and eliminate special provisions IB52 and T23 from § 172.102(c). The purpose of the change is to consolidate the packaging requirements for organic peroxides into one section and to have separate tables for organic peroxides authorized for transport in non-bulk packagings, IBCs, and bulk packagings other than IBCs. The changes are as follows:
Paragraph (a) is revised by adding paragraphs (b) and (b)(6), which state that bulk packagings may require a lower control temperature than those specified for non-bulk packagings and that an organic peroxide not identified in either the Organic Peroxide Table, Organic Peroxide IBC Table, or Organic Peroxide Portable Tank Table must be approved under § 173.128(c).
Paragraph (b) is revised to eliminate all IBC and other bulk packaging authorizations from column 6 of the Organic Peroxide Table. Various obsolete entries were also removed. The current paragraph (b), “Organic Peroxide Table,” is moved to paragraph (c) and the current paragraph (c), “New organic peroxides, formulations and samples,” is moved to paragraph (b).
The notes following the Organic Peroxide Table are changed as follows:
• Revise note 22 to indicate that ethylbenzene with greater than or equal to 25% of dilutant type A is acceptable.
• Revise note 23 to indicate that methyl isobutyl keytone with greater than or equal to 19% of dilutant type A is acceptable.
• Add a new note 29 to identify materials which are not included in the UN Model Regulations and note that a Competent Authority approval is required for international transportation.
• Remove Notes 9, 11, and 14 following the Organic Peroxide Table.
In addition, The Packing Method Table found in paragraph (d), is revised by replacing the 200 kg maximum quantity for solids and combination packagings listed in OP8 with a 400 kg maximum quantity. Note 2, following the table, is revised to allow 200 kg of solid material per box and up to 400 kg of material per authorized combination packaging. The note also indicates that the outer packaging must be a box (4C1, 4C2, 4D, 4F, 4G, 4H1, and 4H2) and each inner packaging must be of plastics or fiber with a maximum net mass of 25 kg. Paragraph (d)(3) is clarified by revising the text to state that the maximum content acceptable for glass receptacles used as inner packagings of a combination packaging is 0.5 kg for solids or 0.5 L for liquids.
A new paragraph (e) is added to include the new “Organic Peroxide IBC Table” that replaces the current “Table 2.—Organic Peroxide IBC Code (IB52)” in § 172.102(c)(4). The new table is revised to add an organic peroxide, “Dicyclohexylperoxydicarbonate, not more than 42% as a stable dispersion, in water.” In addition, the new Organic Peroxide IBC Table identifies, by technical name, those organic peroxides authorized for transportation in the IBCs that are specifically listed in the table.
A new paragraph (f) is added to include the current IBC requirements contained in paragraph (e)(5) of this section. Paragraph (f) also includes requirements that are specific to organic peroxides packaged in IBCs.
A new paragraph (g) is added to include the new “Organic Peroxide Portable Tank Table,” that replaces the current “Portable Tank Code T23” found in § 172.102(c)(7)(iii). The new table is identical to the current table except that for UN 3109, in the entry for Pinanyl hydroperoxyde, 50% is replaced by 56% and all references to self-reactive materials are removed. In addition, the Organic Peroxide Portable Tank Table provides certain portable tank requirements and identifies, by technical name, those organic peroxides authorized for transportation in the bulk packagings listed in the new paragraph (h).
The current paragraph (e) is redesignated as paragraph (h). Paragraph (h) establishes requirements that are specific to organic peroxides packaged in certain bulk packagings. Additionally, the new “Note to Paragraph (h)(3)(vi)” is revised to include changes brought forth by petition for rulemaking P-1428. The petition proposed to amend the current paragraph (e)(3)(vi) and allow for a second but equally acceptable example of an emergency-relief device sizing method to be added to the HMR. We agreed with the petitioner and added a statement to the new paragraph (h)(3)(vi) indicating that an additional example of an emergency-relief device sizing method can be found in the “American Institute of Chemical Engineers Process Safety Progress Journal, June 2002 issue (Vol. 21, No. 2)” as referenced in § 171.7(b).
The changes to this section altered the order of the paragraphs within this section; therefore, various citations were changed. Also, paragraphs referencing IB52 or TP23 are revised to indicate that those provisions no longer exist and the updated requirements are found in paragraph (e) and (g), respectively. A commenter requested that § 173.225 be revised to allow for increased industry flexibility, regulatory uniformity, and to better align with the UN Recommendations. We agree and have made the following revisions:
• Added wording to 173.225(a) to show that organic peroxides that are not identified in the organic peroxide table, but are in paragraph (b)(3) are not subject to the requirements of § 173.128.
• Removed Note 1 from both entries of tert-Butyl cumyl peroxide and Note 11 from Dicumyl peroxide.
• Removed the sentence “The additional requirements in paragraph (h)(5)(i) and (h)(5)(ii) of this section also apply” from § 173.225(f) and renumbered (f)(i) and (f)(ii) as (f)(1) and (f)(2), respectively.
• Revised the introductory text to Paragraph (h) to indicate that the bulk packagings that follow are for materials authorized for transport in a bulk packaging by Paragraph (h) and organic peroxides listed in the Organic Peroxide Portable Tank Table.
• Removed two occurrences of the term “Type F” from Paragraph (h)(3) to broaden the applicability of the provisions.
• Removed statement from § 173.225(h)(3)(xii) indicating that DOT Specification 57 portable tanks are not subject to the requirements of paragraphs (h)(3)(ii) and (h)(3)(iv) of this section.
Sections 173.226 and 173.227
We revised the packaging requirements of §§ 173.226 and 173.227 for materials poisonous by inhalation, Division 6.1, Packing Group I, Hazardous Zone A and Hazard Zone B. These amendments have: Reduced the hydrostatic test pressure of the inner drum in a drum-within-a-drum configuration authorized in § 173.226(b); standardized the minimum thickness requirements of the inner drums in the drum-within-a-drum configuration authorized in §§ 173.226(b) and 173.227(b); clarified the test requirements for inner packaging systems in § 173.226(b)(2)(iv); and in § 173.226(d) added a provision to authorize transportation of PIH materials in single packages when subjected to additional operational controls and approved by the Associate Administrator. Section 173.226(c)(2) is reformatted for ease of understanding. We removed an expired transitional date from paragraph (a) that allows the transport of welded cylinders filled before October 1, 2003 for the purpose of reprocessing or disposal of cylinders's content until December 31, 2003. One commenter recommended that we include a provision in § 173.227(b) to allow for the testing of the outer drum of a drum-in-drum package as either as a package intended to contain inner packagings (combination package) or as a single packaging intended to contain solids or liquids. We agree and have revised § 173.227(b) accordingly. Another commenter suggested that we increase the minimum thickness of a UN 1A1 drum in PIH service from .69 mm to 1.0 mm. Increasing the minimum thickness of a UN 1A1 drum in PIH service was not proposed in this rulemaking and inclusion of such a requirement is beyond the scope of this rulemaking. However, we are reviewing this request for consideration in a future rulemaking.
Section 173.249
Paragraph (c) is revised to be consistent with the current “Bromine” entry in the § 172.101 “Hazardous Material Table” that authorizes the use of a UN portable tank conforming to tank code T22. A commenter suggested that we include a provision authorizing the returning of a tank containing bromine residue. We agree that such a provision is necessary and have amended § 173.249 accordingly.
Sections 173.306 and 173.307
To add clarity to the HMR, the text currently found in § 173.306(i) is removed and replaced with the text
currently found in § 173.307(a)(5). Since § 173.306 is devoted exclusively to limited quantities of compressed gases, relocating § 173.307(a)(5) to § 173.306 makes the exception easier to find.
Section 173.313
A new § 173.313 is added to serve as the new location for the Portable Tank Code T50 Table. The table is renamed “UN Portable Tank Table for Liquefied Compressed Gases.” The table provides the maximum allowable working pressures, bottom opening requirements, pressure relief requirements and degree of filling requirements for liquefied compressed gases permitted for transport in portable tanks. The change relocates these packaging requirements to Part 173, which is a more appropriate location, and makes the special provisions less cumbersome. In addition, the new UN Portable Tank Table for Liquefied Compressed Gases is amended by revising the Column 3 heading to read “Minimum design pressure (bar) * * *” The values in column 3 are actually minimum values, however the title of the column is misleading because it uses the term “Maximum allowable working pressure (bar) * * *”
Section 173.315
In paragraph (a), the reference to “portable tank provision T50 in § 172.102” is revised to read “the UN Portable Tank Table for Liquefied Compressed Gases in § 173.313.”
Section 173.323
After further considering the proposed changes to the packaging authorizations for ethylene oxide in § 173.323, we noted that the total quantity per package of ethylene oxide authorized for transport when glass inner receptacles are used was proposed to be increased from 100 grams to 2.5 kg. Due to the extremely flammable and explosive properties of ethylene oxide and the fragile properties of glass, after further consideration we have chosen not to adopt the 2.5 kg outer package limit found in the UN Recommendations and to retain our current outer package limit of 100 grams. The total quantity per package when metal inner receptacles are used will remain unchanged from the proposed 2.5 kg. In this rule, paragraphs (b)(1)-(b)(3) are revised and consolidated for consistency with current international requirements for the transportation of ethylene oxide in combination packagings. Paragraphs (b)(1)-(b)(3) provide the current authorizations for glass, aluminum, and metal receptacles respectively. Amendments to this section include (1) removing the HMR limitation of 12 inner receptacles per outer package currently applied to aluminum and other metal receptacles, (2) removing the overpack restriction in (b)(2) which specifies a maximum of 10 boxes per overpack, (3) requiring a hot water bath test for all inner receptacles, (4) removing the pressure relief device and burst pressure requirements currently applied to metal receptacles, (5) applying the same outer package authorizations consistently to all inner packaging types and allowing any outer package authorized in § 172.201(b), and (6) requiring all inner packagings to be suitably cushioned (the top and bottom pad and perimeter liner requirement currently only applied to outer packages containing aluminum inner packagings is removed). Though we are eliminating the option to utilize certain packaging authorizations for glass and aluminum inner packagings, we believe that this change will have little or no economic impact on the ethylene oxide industry because of the amount of materials that are transported in international commerce. 3M Package Engineering requested that we reduce the maximum quantity of ethylene oxide permitted in any metal inner packaging from 340 g (12 ounces) to 200 g (7 ounces). They stated that such a change would more adequately align the HMR with international standards. We agree that such a change would align the HMR with international requirements. However, allowing a metal inner packaging to contain a maximum quantity of 340 g (12 ounces) does not limit compliance with international requirements. In addition, we cannot adopt the 200 g (7 ounces) limitation in this rulemaking because such a change would be more restrictive then the requirements we proposed. We may consider adopting the 200 g (7 ounces) limitation in a future rulemaking.
Part 175
Section 175.10
Consistent with an amendment to the ICAO TI, we are requiring that aerosol cans that are carried aboard an aircraft in accordance with § 175.10(a)(4) have their release devices protected by a cap or other suitable means. In addition, the ICAO Dangerous Goods Panel will convene a series of working groups to develop recommendations for consideration during the 20th session of the Dangerous Goods Panel to further review this issue. These recommendations may lead to additional amendments to the ICAO TI. Finally, we note that non-flammable gases (
e.g.
, nitrogen) other than carbon dioxide are used for the operation of mechanical limbs. Consistent with an amendment to the ICAO TI, we are proposing to provide an exception from the HMR for mechanical limbs that are powered by any Division 2.2 gas. One commenter recommended that the release device requirements added to § 175.10 also be incorporated into Part 173. Specifically, they requested that aerosol cans that are transported in commerce be protected by a cap or other suitable means to prevent inadvertent release. They indicated that this change should be coordinated with the Federal Aviation Administration (FAA). We disagree. Section 173.24(b)(1) states that each package used for the shipment of hazardous materials must be constructed, maintained, filled, its contents so limited, and closed, so that under conditions normally incident to transportation there will be no identifiable release of hazardous materials to the environment. We feel this section adequately addresses the commenter's concerns, and allows shippers the flexibility to properly protect aerosol cans.
Section 175.85
In § 175.85, a new paragraph (j) is added to specify the cargo location of a package bearing the “KEEP AWAY FROM HEAT” handling marking.
Part 176
Section 176.2
Certain definitions are revised. The definitions for “Explosive article” and “Explosive substance” are revised to remove an incorrect reference. The definition for “Magazine” is revised to include a compartment in the vessel. The definition for “Magazine” is also revised to specify vessel storage location and accessibility. The term “Transport unit” is revised to read “Cargo transport unit” to be consistent with Amendment 32 of the IMDG Code. In addition, in the definition “In containers or the like” the term “transport unit” is removed and the term “cargo transport unit” is added in its place.
Section 176.27
In this section, the words “transport unit” are replaced with the words “transport vehicle” in each place they appear to be consistent with the removal of the term “transport unit” from the definitions in § 176.2.
Section 176.63
Paragraph (e) is revised to align the definition of “Closed cargo transport unit” to be consistent with the
definition in Amendment 32 of the IMDG Code.
Section 176.76
Paragraph (i) is revised to clarify that for container ships, a distance equivalent to one container space athwartships (
i.e.
, in the direction of the breadth of the vessel) away from possible sources of ignition applied in any direction satisfies the requirement that a cargo transport unit packed or loaded with flammable gas or flammable liquid having a flashpoint below +23 °C transported on deck be stowed “away from” possible ignition sources. This is consistent with Amendment 32 of the IMDG Code. In addition, in paragraphs (h) and (i), the words “transport unit” are removed and replaced with the words “cargo transport unit” in each place they appear to be consistent with Amendment 32 of the IMDG.
Section 176.83
Paragraph (l) is revised to correct an error pertaining to the Segregation Table that sets forth the general requirements for segregation of containers on board hatchless container vessels. In addition, throughout the section the words “transport units” are removed and replaced with the words “cargo transport units” in each place they appear to be consistent with Amendment 32 of the IMDG. A new paragraph (m) is added to specify the provisions for segregation groups.
Section 176.84
Paragraph (a) is revised to specify the various chemical groups listed in the segregation table. In the paragraph (b) Table of Provisions, we added eleven new provisions (codes) for certain stowage and segregation requirements for hazardous materials that are transported by vessel. In addition, in paragraph (c)(2) Provisions for the stowage of Class 1 (explosive) materials, we revised three notes. The terms “separated from” and “away from” in the codes are defined in § 176.83 of the HMR.
Code 133 is added to the entries “Barium chlorate solution,” UN3405; “Barium perchlorate solution,” UN3406; and “Chlorate and magnesium chloride mixture solution,” UN3407, that requires the material to be stowed “separated from” sulfur.
Code 134 is added to the entry “Aluminum alkyl halides, solid,” UN3461, that requires the material to be stowed “separated from” UN2716.
Code 135 is added to the entries “Methylamine, aqueous solution,” UN1235 and “Trimethylamine, aqueous solutions,” UN1297, that requires the material to be stowed “separated from” mercury and mercury compounds.
Code 136 is added to the entry “Tributylphosphane,” UN3254, that requires the material to be stowed “separated from” carbon tetrachloride.
Code 137 is added to the entries “Arsenic compounds, liquid, n.o.s.,” UN1556 and “Arsenic compounds, solid, n.o.s.,” UN1557, that requires arsenic sulphides to be stowed “separated from” acids.
Code 138 is added to the entries for UN1448; UN1456; UN1479; UN1482; UN1490; UN1503; UN1515; UN3085; UN3087; UN3098; UN3099; UN3139; and UN3214, that requires the material to be stowed “separated from” peroxides.
Code 139 is added to the entry “1, 4-Butynediol,” UN2716, that requires the material to be stowed “separated from” mercury salts.
Code 140 is added to the entry “1, 4-Butynediol,” UN2716, that requires the material to be stowed “separated from” UN3052 and UN3461.
Code 141 is added to the entries for UN1732; UN1755; UN1806; UN1908; UN2433; UN2859; and UN2861, that requires the material to be stowed “away from” radioactive materials.
Code 142 is added to the entries for UN1748; UN2208; and UN2880, that requires packages in cargo transport units to be stowed so as to allow for adequate air circulation throughout the cargo.
Code 143 is added to the entry for Organometallic Substance, Liquid, Pyrophoric, UN3392, prohibiting transportation on any vessel carrying explosives (except explosives in Division 1.4, compatibility group S.
Note 19E is revised to specify that materials under entries NA0331; UN0004; UN0222; UN0241; and UN0402 must be stowed “away from” explosives containing chlorates or perchlorates.
Note 22E is revised to specify that materials under the entry “Explosive, blasting, type C,” must be stowed “away from” ammonium compounds and explosives containing ammonium compounds or salts.
Note 23E is revised to specify that materials under entries UN0247; UN0395; UN0396; UN0397; UN0398; UN0399; UN0400; UN0449; and UN0450 must be “separated from” Division 1.4 and “separated longitudinally by an intervening complete compartment or hold from” Division 1.1, 1.2, 1.3, 1.5, and 1.6 except from explosives of compatibility group J.
A commenter questioned how adequate air circulation was achieved in a cargo transport unit. In addition, the commenter stated that it fails to understand why air circulation is necessary in a closed cargo transport unit, as indicated by Stowage Provision 142. Stowage Provision 142 indicates that packages in cargo transport units must be stowed so as to allow for adequate air circulation throughout the cargo. We feel cargo transport units that are properly loaded will allow for the adequate circulation of air by natural means so as to safeguard against excessive heat buildup within the cargo.
Section 176.116
In paragraph (c), the words “transport units” are revised to read “cargo transport units.” In addition, a new paragraph (f) is added to specify the under deck stowage requirements of Class 1 (explosive) materials allocated stowage categories 09 and 10.
Sections 176.122 and 176.124
Sections 176.122 and 176.124 are removed and reserved.
Section 176.128
In § 176.128, the section heading and section are revised.
Section 176.132
Section 176.132 is removed and reserved.
Section 176.133

Section 176.138
Paragraph (a) is removed and reserved to be consistent with Amendment 32 of the IMDG Code. This paragraph currently requires Class 1 (explosive) material that is stowed on deck to be carried as close to the vessel's centerline as practicable.(See also change to § 176.170.)
Section 176.142
Paragraph (a) is revised to remove “Pyrophoric organometallic compound, water-reactive, n.o.s.” from the list of liquid hazardous materials of extreme flammability that may not be transported in a vessel carrying Class 1 (explosive) materials. Additionally, we added to the above list the following new liquid entries:
• “Organometallic substance, liquid, pyrophoric, UN3392”
• “Organometallic substance, liquid, pyrophoric, water-reactive, UN3394”
These changes are consistent with Amendment 32 of the IMDG Code.
Section 176.144
In this section, the words “transport unit” are replaced with the words “cargo transport unit” in each place they appear to be consistent with the definition in Amendment 32 of the IMDG Code. Additional notes are added to Table 176.144(a)—“Authorized Mixed Stowage For Explosives” to address additional exceptions for mixed stowage of Class 1 materials.
Section 176.146
In § 176.146, in paragraph (d)(1), the wording “transport units” is revised to read “cargo transport units.”
Section 176.168
In § 176.168, in the title before the section heading, the wording “TRANSPORT UNITS AND SHIPBORNE BARGES” are revised to read “CARGO TRANSPORT UNITS AND SHIPBORNE BARGES.”
Section 176.170
A new paragraph (b) is added to prohibit freight containers loaded with Class 1 (explosive) materials, except for explosives in Division 1.4, from being stowed in the outermost row of containers. This change is consistent with Amendment 32 of the IMDG Code.
Section 176.174
Paragraphs (a) and (b) are revised to remove the references to portable magazines. This change is consistent with Amendment 32 of the IMDG Code.
Section 176.600
In § 176.600, in paragraph (a), the wording “closed transport units” is revised to read “closed cargo transport units.”
Part 178
Section 178.274
Paragraph (f)(v) is revised to more clearly specify the rated flow capacity marking required to be placed on every UN portable tank's pressure relief device.
Section 178.275
Paragraph (i)(2) is revised to more clearly specify the combined delivery capacity of UN portable tank's pressure relief systems.
Section 178.276
In paragraph (a)(4)(ii)(A), the reference to “portable tank special provision T50” is revised to read “the UN Portable Tank Table for Liquefied Compressed Gases in § 173.313.” In addition, paragraph (d), the reference to “portable tank special provision T50 in § 172.102(c)(7)” is revised to read “UN Portable Tank Table for Liquefied Compressed Gases in § 173.313.” Finally, in paragraph (e)(3), the reference to “portable tank special provision T50 in § 172.102” is revised to read “the UN Portable Tank Table for Liquefied Compressed Gases in § 173.313.”
Section 178.602
Paragraph (b) is revised to clarify the requirements applicable to filling packaging other than bags in preparation for testing.
Section 178.603
Paragraph (c) is revised to add a definition indicating that a minimum specific gravity for solutions of water and anti-freeze is 0.95 for testing at 18 °C (0 °F) or lower. Additionally, in paragraph (e), we specify the drop test height for liquids in single packagings and for inner packagings of combination packagings, when the test is performed in water.
Section 178.810
Paragraph (b)(3) is revised to specify that water/anti-freeze solutions with a minimum specific gravity of 0.95 for testing at −18 °C (0 °F) or lower are acceptable test liquids for use when conducting IBC drop tests. This is consistent with our amendment to § 178.603(c)(1) regarding the testing of non-bulk packages. In addition, we added a sentence to clarify that when conditioning is required by § 178.810(b), the conditioning specified in § 178.802 (which requires a higher temperature) does not apply.We received a comment from the Reusable Industrial Packaging Association (RIPA) concerning this revision. RIPA believes that RSPA intended to clarify that water/antifreeze solutions with a minimum specific gravity of 0.95 are equivalent for testing purposes to IBCs containing only water, thereby eliminating the need to adjust the drop height of test units. RIPA stated that § 178.810(b)(3) should be revised to indicate that this solution may be considered equivalent to water for testing purposes. We agree and have revised the section accordingly.
Part 180
Section 180.350
Paragraph (c) is revised to expand the definition of routine maintenance of IBCs to include flexible, plastic and textile IBCs.
Section 180.352
Paragraph (d)(1)(iv) is revised to require persons other than the owner of metal, rigid plastics, and composite IBCs to mark the IBC indicating routine maintenance has been performed when such maintenance is performed. A new paragraph (d)(1)(v) is added to this section. This paragraph states that retests and inspections performed under paragraphs (d)(1)(i) and (ii) of this section may be used to satisfy the tests and inspections required by paragraph (b) of this section. This addition incorporates changes made to the 12th revised edition of the Transport of Dangerous Goods Model Regulations into the HMR. Three commenters requested that we revise § 180.352 to distinguish requirements applicable to repair and routine maintenance of IBCs. We agree and have revised § 180.352 creating a new paragraph entitled, “Requirements applicable to routine maintenance of IBCs.”
V. Regulatory Analyses and Notices
A. Statutory/Legal Authority for This Rulemaking
This final rule is published under the following statutory authorities:
1. 49 U.S.C. 5103(b) authorizes the Secretary of Transportation to prescribe regulations for the safe transportation, including security, of hazardous material in intrastate, interstate, and foreign commerce. This final rule amends regulations to maintain alignment with international standards by incorporating various amendments, including changes to proper shipping names, hazard classes, packing groups, special provisions, packaging authorizations, air transport quantity limitations and vessel stowage requirements. To this end, as discussed in detail earlier in this preamble, the final rule amends the HMR to more fully align it with the biennial updates of the UN Recommendations, the IMDG Code and the ICAO Technical Instructions to facilitate the transport of hazardous materials in international commerce.
2. 49 U.S.C. 5120(b) authorizes the Secretary of Transportation to ensure that, to the extent practicable, regulations governing the transportation of hazardous materials in commerce are consistent with standards adopted by international authorities. This final rule amends the HMR to maintain alignment with international standards by incorporating various amendments to facilitate the transport of hazardous material in international commerce. To this end, as discussed in detail earlier in this preamble, the final rule incorporates changes into the HMR
based on the Thirteenth Revised Edition of the UN Recommendation, Amendment 32 to the IMDG Code, and the 2005-2006 ICAO Technical Instructions, which become effective January 1, 2005. The continually increasing amount of hazardous materials transported in international commerce warrants the harmonization of domestic and international requirements to the greatest extent possible. Harmonization serves to facilitate international transportation; at the same time, harmonization ensures the safety of people, property, and the environment by reducing the potential for confusion and misunderstanding that could result if shippers and transporters were required to comply with two or more conflicting sets of regulatory requirements. While the intent of this rulemaking is to align the HMR with international standards, we review and consider each amendment on its own merit based on its overall impact on transportation safety and the economic implications associated with its adoption into the HMR. Our goal is to harmonize without sacrificing the current HMR level of safety and without imposing undue burdens on the regulated public. Thus, as discussed in detail earlier in this preamble, there are several instances where we elected not to adopt a specific provision of the UN Recommendations, the IMDG Code or the ICAO Technical Instructions; further, we are maintaining a number of current exceptions for domestic transportation that should minimize the compliance burden on the regulated community.
B. Executive Order 12866 and DOT Regulatory Policies and Procedures
This final rule is not considered a significant regulatory action under section 3(f) of Executive Order 12866 and, therefore, was not reviewed by the Office of Management and Budget. This final rule is not considered a significant rule under the Regulatory Policies and Procedures of the Department of Transportation [44 FR 11034]. Benefits resulting from the adoption of the amendments in this final rule include enhanced transportation safety resulting from the consistency of domestic and international hazard communications and continued access to foreign markets by domestic shippers of hazardous materials. This final rule applies to offerors and carriers of hazardous materials, such as chemical manufacturers, chemical users and suppliers, packaging manufacturers, distributors, battery manufacturers, radiopharmaceutical companies, and training companies.
The majority of amendments in this final rule should result in cost savings and ease the regulatory compliance burden for shippers engaged in domestic and international commerce, including trans-border shipments within North America. For example, cost savings will be realized by shippers and carriers as a result of the following:
—Eliminating the air eligibility marking requirement.
—Amendments allowing numerous Class 3, PG II materials with a Class 8 sub-risk and others to be transported as a limited quantity.
—Allowing cylinders to be used for many more substances than currently authorized.
—Allowing salvage packagings to be used for non-conforming packages; and generally minimizing differences between U.S. and international hazardous materials transportation regulations.
We are authorizing a delayed effective date and a one-year transition period to allow for training of employees and to ease any burden on entities affected by the amendments. The total net increase in costs to businesses in implementing this rulemaking is considered to be minimal and a regulatory evaluation is available for review in the Docket.
C. Executive Order 13132
This final rule has been analyzed in accordance with the principles and criteria contained in Executive Order 13132 (“Federalism”). This final rule preempts State, local and Indian tribe requirements but does not propose any regulation that has substantial direct effects on the States, the relationship between the national government and the States, or the distribution of power and responsibilities among the various levels of government. Therefore, the consultation and funding requirements of Executive Order 13132 do not apply.
The Federal hazardous material transportation law, 49 U.S.C. 5101-5127, contains an express preemption provision (49 U.S.C. 5125(b)) that preempts State, local, and Indian tribe requirements on certain covered subjects. Covered subjects are:
(1) The designation, description, and classification of hazardous materials;
(2) The packing, repacking, handling, labeling, marking, and placarding of hazardous materials;
(3) The preparation, execution, and use of shipping documents related to hazardous materials and requirements related to the number, contents, and placement of those documents;
(4) The written notification, recording, and reporting of the unintentional release in transportation of hazardous; and
(5) The design, manufacture, fabrication, marking, maintenance, recondition, repair, or testing of a packaging or container represented, marked, certified, or sold as qualified for use in transporting hazardous material.
This final rule addresses covered subject items (1), (2), (3), and (5) above and preempts State, local, and Indian tribe requirements not meeting the “substantively the same” standard. This final rule is necessary to incorporate changes adopted in international standards, effective January 1, 2005. If the changes in this final rule are not adopted in the HMR, U.S. companies, including numerous small entities competing in foreign markets, are at an economic disadvantage. These companies are forced to comply with a dual system of regulations. The changes in this rulemaking are intended to avoid this result. Federal hazardous materials transportation law provides at section 5125(b)(2) that, if DOT issues a regulation concerning any of the covered subjects, DOT must determine and publish in the
Federal Register
the effective date of Federal preemption. The effective date may not be earlier than the 90th day following the date of issuance of the final rule and not later than two years after the date of issuance. The effective date of Federal preemption is March 21, 2005.
D. Executive Order 13175
This final rule was analyzed in accordance with the principles and criteria contained in Executive Order 13175 (“Consultation and Coordination with Indian Tribal Governments”). Because this final rule does not have tribal implications, does not impose substantial direct compliance costs, and is required by statute, the funding and consultation requirements of Executive Order 13175 do not apply.
E. Regulatory Flexibility Act, Executive Order 13272, and DOT Procedures and Policies
The Regulatory Flexibility Act (5 U.S.C. 601
et seq.
) requires an agency to review regulations to assess their impact on small entities, unless the agency determines that a rule is not expected to have a significant impact on a substantial number of small entities. This final rule facilitates the transportation of hazardous materials in international commerce by providing consistency with international standards. This final rule applies to offerors and carriers of hazardous materials, some of whom are small entities, such as chemical users and suppliers, packaging manufacturers, distributors, battery manufacturers, and
training companies. As discussed above, under
Executive Order 12866
, the majority of amendments in this final rule should result in cost savings and ease the regulatory compliance burden for shippers engaged in domestic and international commerce, including trans-border shipments within North America.
Many companies will realize economic benefits as a result of these amendments. Additionally, the changes brought forth by this final rule will relive U.S. companies, including small entities competing in foreign markets, from the burden of complying with a dual system of regulations. Therefore, I certify that these amendments will not, if promulgated, have a significant economic impact on a substantial number of small entities.
This final rule has been developed in accordance with Executive Order 13272 (“Proper Consideration of Small Entities in Agency Rulemaking”) and DOT's procedures and policies to promote compliance with the Regulatory Flexibility Act to ensure that potential impacts of draft rules on small entities are properly considered.
F. Paperwork Reduction Act
Under the Paperwork Reduction Act of 1995, no person is required to respond to a collection of information unless it displays a valid Office of Management and Budget (OMB) control number. Section 1320.8(d), Title 5, Code of Federal Regulations requires that RSPA provide interested members of the public and affected agencies an opportunity to comment on information collection and recordkeeping requests. RSPA currently has two approved information collections affecting this final rule: OMB Control Number 2137-0557, “Approvals for Hazardous Materials” with 25,605 burden hours and $562,837.40 burden costs; and OMB Control Number 2137-0613, “Subsidiary Hazard Class & Number/Type of Packagings” with 63,309 burden hours and $216,705 burden costs.
There are minor editorial changes under this rule. However, there is no net increase in burden for OMB Control Number 2137-0557 or OMB Control Number 2137-0613. We estimate that the total information collection and recordkeeping burden as follows:
“Approvals for Hazardous Materials”
OMB Number 2137-0557:
Total Annual Number of Respondents:
3,523.
Total Annual Responses:
3,874.8.
Total Annual Burden Hours:
25,605.
Total Annual Burden Cost:
$562,837.40.
“Subsidiary Hazard Class & Number/Type of Packagings”
OMB Number 2137-0613:
Total Annual Number of Respondents:
250,000.
Total Annual Responses:
6,337,500.
Total Annual Burden Hours:
17,604.
Total Annual Burden Cost:
$216,705.
Total First Year Burden Hours:
45,705.
Total First Year Burden Cost:
$1,115,992.
Requests for a copy of this information collection should be directed to Deborah Boothe or T. Glenn Foster, Office of Hazardous Materials Standards (DHM-10), Research and Special Programs Administration, Room 8422, 400 Seventh Street, SW., Washington, DC 20590-0001, telephone (202) 366-8553.
G. Regulatory Identifier Number (RIN)
A regulation identifier number (RIN) is assigned to each regulatory action listed in the Unified Agenda of Federal Regulations. The Regulatory Information Service Center publishes the Unified Agenda in April and October of each year. The RIN contained in the heading of this document can be used to cross-reference this action with the Unified Agenda.
H. Unfunded Mandates Reform Act
This final rule does not impose unfunded mandates under the Unfunded Mandates Reform Act of 1995. It does not result in costs of $120.7 million or more to either State, local or tribal governments, in the aggregate, or to the private sector, and is the least burdensome alternative that achieves the objective of the rule.
I. Environmental Assessment
The National Environmental Policy Act of 1969 (NEPA) requires Federal agencies to consider the consequences of major Federal actions and prepare a detailed statement on actions significantly affecting the quality of the human environment. We developed an assessment to determine the effects of these revisions on the environment and whether a more comprehensive environmental impact statement may be required. Our findings conclude that there are no significant environmental impacts associated with this final rule. Consistency in the regulations for the transportation of hazardous materials aids in the shipper's understanding of what is required and permits shippers to more easily comply with safety regulations and avoid the potential for environmental damage or contamination. For interested parties, an environmental assessment is available in the public docket.
J. Privacy Act
Anyone is able to search the electronic form of any written communications and comments received into any of our dockets by the name of the individual submitting the document (or signing the document, if submitted on behalf of an association, business, labor union, etc.).

(B) When the proper shipping description for a sample is assigned a “G” in Column (1) of the § 172.101 Table, and the primary constituent(s) for which the tentative classification is based are not known, the provisions requiring a technical name for the constituent(s) do not apply; and
(C) A sample must be transported in a combination packaging that conforms to the requirements of this subchapter that are applicable to the tentative packing group assigned, and may not exceed a net mass of 2.5 kg (5.5 pounds) per package.
Note to Paragraph (c)(11): For the transportation of self-reactive, organic peroxide and explosive samples, see §§ 173.224(c)(3), 173.225(b)(2) and 173.56(d) of this subchapter, respectively.

Bulk packaging.
Column 8C specifies the section in part 173 of this subchapter that prescribes packaging requirements for bulk packagings, subject to the limitations, requirements and additional authorizations of Column 7. A “None” in this column means bulk packagings are not authorized, except as may be provided by special provisions in Column 7. Additional authorizations and limitations for use of UN portable tanks are set forth in Column 7. For each reference in this column to a material that is a hazardous waste or a hazardous substance, and whose proper shipping name is preceded in Column 1 of the Table by the letter “A” or “W” and that is offered for transportation or transported by a mode in which its transportation is not otherwise subject to the requirements of this subchapter:
