I. Executive Summary Back to Top

PHMSA has initiated a rulemaking project to maintain alignment with international regulations and 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. This rulemaking project is part of our ongoing biennial process to harmonize the Hazardous Materials Regulations (HMR; 49 CFR parts 171 to 180) with international regulations and standards.

Federal law and policy strongly favor the harmonization of domestic and international standards for hazardous materials transportation. The Federal hazardous materials transportation law (Federal hazmat law; 49 U.S.C. 5101 et seq.) permits PHMSA to depart from international standards to promote safety or other overriding public interest, but otherwise requires PHMSA to align the HMR with international transport standards and requirements to the extent practicable (see 49 U.S.C. 5120).

Harmonization facilitates international trade by minimizing the costs and other burdens of complying with multiple or inconsistent safety requirements for transportation of hazardous materials to and from the United States and becomes increasingly important as the volume of hazardous materials transported in international commerce grows. By facilitating compliance, harmonization also tends to enhance safety for international movements, but only if the international standards themselves provide an appropriate level of safety. To that end, PHMSA actively participates in the development of international standards for the transportation of hazardous materials, frequently advocating the adoption in international standards of particular HMR requirements.

When considering the adoption of international standards under the HMR, we review and consider each amendment on its own merit, on the basis of its overall impact on transportation safety, and the economic implications associated with its adoption into the HMR. Our goal is to harmonize without diminishing the level of safety currently provided by the HMR and without imposing undue burdens on the regulated community.

This NPRM proposes to amend the HMR to maintain alignment with various international standards. The following are some of the more noteworthy proposals in this NPRM:

  • Incorporate Revised Standards: PHMSA proposes to incorporate by reference the newest versions of various international hazardous materials standards including the 2013-2014 International Civil Aviation Organization Technical Instructions for the Safe Transport of Dangerous Goods by Air (ICAO Technical Instructions), Amendment 36-12 to the International Maritime Dangerous Goods Code (IMDG Code), and the 17th Revised Edition of the United Nations Recommendations on the Transport of Dangerous Goods (UN Model Regulations). Additionally, we are proposing to update our incorporation by reference of the Canadian Transportation of Dangerous Goods Regulations to include Amendment 8 (SOR/2011-239) issued November 9, 2011, Amendment 9 (SOR/2011-60) issued March 16, 2011, and Amendment 10 (SOR/2011-210) issued October 12, 2011. Finally, in this NPRM PHMSA is proposing the adoption of updated International Standards Organization (ISO) standards.

If the amendments in this proposed rule are not adopted in the HMR by January 1, 2013, the date most of the international standards above take effect, U.S. companies, including numerous small entities competing in foreign markets, would be at an economic disadvantage. These companies would be forced to comply with a dual system of regulations. The amendments proposed in this rulemaking are intended to avoid this result.

  • Expand Packaging Authorizations: Consistent with amendments adopted by the UN Model Regulations, PHMSA proposes to adopt changes throughout the Part 173 packaging requirements to authorize more flexibility when choosing packages for hazardous materials. These changes include, but are not limited to, the authorization to allow wood as a material of package construction for certain explosives the authorization to use metals other than steel or aluminum for drums and boxes; and the authorization, where appropriate, to permit the use of non-removable head drums in those instances where removable head drums are otherwise authorized.

These amendments will allow additional flexibility to the regulated community with respect to the material of construction authorized for such packages and types of packages authorized, without compromising safety.

  • Revise Vessel Stowage Codes: PHMSA proposes to revise, consolidate, and delete various vessel stowage codes. Specifically, PHMSA is proposing to revise the vessel stowage location requirements for explosives by reducing the number of explosive stowage categories from 15 to 5 in column 10A of the Hazardous Materials Table (HMT) found in § 172.101. In addition to the changes in column 10A, in this NPRM PHMSA is proposing modifications to the vessel stowage codes listed in column 10B of the HMT. These changes are designed to harmonize with the IMDG Code, reduce the number of redundant vessel stowage codes and add various vessel segregation definitions in § 176.2.

These revisions to the vessel stowage requirements in column 10 of the HMT are proposed to eliminate redundant codes, align with modifications to the IMDG Code and to simplify the vessel stowage requirements by limiting the number of stowage options without compromising safety. PHMSA believes these changes will greatly simplify vessel stowage requirements and facilitate international transportation of hazardous materials in commerce by aligning the HMR with the IMDG Code, while continuing to achieve an appropriate level of safety.

  • Adopt Flexible Bulk Container Requirements: PHMSA proposes to incorporate a new packaging definition, operational controls, performance-oriented standards, and testing requirements for Flexible Bulk Containers (FBCs). FBCs are bulk packages with a capacity over the currently authorized maximum volumetric capacity for IBCs. The maximum proposed volumetric capacity of FBCs is 15 cubic meters. PHMSA proposes to harmonize with the internationally recognized definition of FBCs, adopt performance-oriented packaging design and testing standards for FBCs, and impose operational controls on the use of FBCs in transport. These FBC requirements will be modeled after the FBC requirements adopted into the 17th Revised Edition of the UN Model Regulations.

FBCs provide shippers the opportunity to utilize a reusable packaging for bulk shipments of certain authorized low-hazard commodities. The associated design-type testing requirements ensure a high level of packaging integrity, and experience with such packagings in international transportation has verified the safety of these packagings.

  • Adopt Chemical Under Pressure Provisions: We are proposing to revise the HMT to include entries for chemical under pressure as well as incorporate other safety requirements including but not limited to packaging requirements, segregation requirements, quantity limitations, and filling limits into the HMR.

There is often confusion with regard to the proper classification of chemical under pressure. Currently, these types of products are often incorrectly classified and transported as liquefied gases or shipped under special permits. The addition of packaging requirements specific to chemical under pressure will ensure that an appropriate level of safety is achieved for these unique materials.

  • Specify Minimum Size Requirements for Identification Number Markings on Non-Bulk Packages: PHMSA proposes to add specific size requirements for identification number (i.e., “UN,” “NA,” “ID”) markings as prescribed in § 172.301 for non-bulk packages. PHMSA proposes this minimum size marking for the “UN,” “NA,” and “ID” markings to align with newly adopted requirements in the 17th Revised Edition of the UN Model Regulations.

PHMSA recognizes the importance of establishing a minimum size requirement for the internationally recognized “UN” identification number marking system. Without a minimum size requirement for hazard communication, shippers may mark packages in a format that makes it difficult for first responders to identify the commodity associated with a particular package.

  • Revise HMT Entries: In this NPRM, PHMSA proposes amendments to the § 172.101 Hazardous Materials Table (HMT) to add, revise, or remove certain proper shipping names, hazard classes, packing groups, special provisions, packaging authorizations, bulk packaging requirements, passenger and cargo aircraft maximum quantity limits. The proposed changes to the HMT mirror recent changes in the Dangerous Goods list of The 17th Revised Edition of the UN Model Regulations, the IMDG Code, and the ICAO Technical Instructions.

If adopted in a final rule, the amendments proposed in this NPRM will result in minimal burdens on the regulated community. The benefits resulting from the adoption of the amendments include enhanced transportation safety resulting from the consistency of domestic and international hazard communication and continued access to foreign markets by U.S. manufacturers of hazardous materials. The majority of amendments in this NPRM 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.

PHMSA solicits comments on the need for these amendments and others proposed in this NPRM. Specifically, PHMSA requests comments on the benefits and costs of international harmonization, including the impact on safety and any other relevant concerns regarding the amendments proposed in this NPRM. In addition, PHMSA solicits comment from the regulated community regarding approaches to reducing the costs of this rule while maintaining or increasing the benefits. In its preliminary analysis, PHMSA concluded that the aggregate benefits justify the aggregate costs as a result of the amendments proposed in this NPRM. Nonetheless, PHMSA solicits public comment on specific changes (for example, greater flexibility with regard to a particular amendment) that might improve the rule.

II. Background Back to Top

In a final rule published December 21, 1990 (Docket HM-181; 55 FR 52402), the Research and Special Programs Administration (RSPA), the predecessor agency to PHMSA, comprehensively revised the HMR to harmonize U.S. hazardous materials transportation requirements with the UN Model Regulations. The UN Model Regulations constitute a set of recommendations issued by the UNSCOE and the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). The UN Model Regulations are amended and updated biennially by the UNSCOE and serve as the basis for national, regional, and international modal regulations, including the IMDG Code and the ICAO Technical Instructions.

Since publication of the 1990 rule, PHMSA has issued nine additional international harmonization rulemakings under Dockets: HM-215A [59 FR 67390]; HM-215B [62 FR 24690]; HM-215C [64 FR 10742]; HM-215D [66 FR 33316]; HM-215E [68 FR 44992]; HM-215G [69 FR 76044]; HM-215I [71 FR 78595]; HM-215J [74 FR 2200]; and HM-215K [76 FR 3308]. These rulemakings were based on biennial updates of the UN Model Regulations, the IMDG Code, and the ICAO Technical Instructions.

Federal law and policy strongly favor the harmonization of domestic and international standards for hazardous materials transportation. The Federal hazardous materials transportation law (Federal hazmat law; 49 U.S.C. 5101 et seq.) directs PHMSA to participate in relevant international standard-setting bodies and encourages alignment of the HMR with international transport standards to the extent practicable while recognizing that deviations may at times be necessary to be consistent with the public interest (see 49 U.S.C. 5120). Harmonization facilitates international trade by minimizing the costs and other burdens of complying with multiple or inconsistent safety requirements for transportation of hazardous materials. Harmonization has also become increasingly important as the volume of hazardous materials transported in international commerce grows. By facilitating compliance, harmonization enhances safety. PHMSA actively participates in relevant international standard-setting bodies and promotes the adoption of standards consistent with the high safety standards set by the HMR.

When considering alignment of the HMR with international standards, we review and evaluate each amendment on its own merit, on the basis of its overall impact on transportation safety, and the on the basis of 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 or imposing undue burdens on the regulated community.

Based on this review and evaluation, in this NPRM PHMSA is proposing to revise the HMR to incorporate changes from the 17th Revised Edition of the UN Model Regulations, Amendment 36-12 to the IMDG Code, and the 2013-2014 ICAO Technical Instructions, which become effective January 1, 2013 (The IMDG Code is effective January 1, 2013; however, the previous amendment may continue to be used until January 1, 2014).

In addition, PHMSA proposes to incorporate by reference (see 171.8) the newest editions of various international standards. These standards incorporated by reference are authorized for use, under specific circumstances, in Subpart C of Part 171 of the HMR. This proposed rule is necessary to incorporate revisions to the international standards and, if adopted in the HMR, will be effective January 1, 2013.

Possible Interim Final Rule

If the changes in this proposed rule are not adopted by January 1, 2013, U.S. companies, including numerous small entities competing in foreign markets, would be at an economic disadvantage because these companies would be forced to comply with a dual system of regulations (specifically, the U.S. HMR, UN Model Regulations, and ICAO Technical Instructions). As previously noted, the changes to the international standards will take effect on January 1, 2013. Therefore, it is essential that a final rule incorporating these standards by reference be published no later than December 31, 2012 with an effective date of January 1, 2013. To this end, if it appears a final rule under this docket will not be published prior to January 1, 2013, PHMSA will publish a bridging document in the form of an interim final rule to amend the HMR by incorporating the 17th Revised Edition of the UN Recommendations and the 2013-2014 ICAO Technical Instructions.

With regard to Amendment 36-12 of the IMDG Code, the International Maritime Organization approved an implementation date of January 1, 2014. The current edition of the IMDG Code (Amendment 35-10) remains in effect through 2013 and, therefore, the newest version of the IMDG Code will not be included in any bridging document. The proposed incorporation by reference of the newest edition of the IMDG Code and all other changes proposed in this NPRM would be addressed in a subsequent final rule also under this Docket, PHMSA-2012-0027 (HM-215L). Accordingly, any interim final rule will only incorporate by reference editions of the international standards that become effective on January 1, 2013.

III. Harmonization Proposals in this NPRM Back to Top

In addition to various revisions of the HMT and special provisions, in this NPRM, PHMSA is proposing the following amendments to harmonize the HMR with the most recent revisions to the UN Model Regulations, ICAO Technical Instructions, and the IMDG Code:

Chemical under pressure

Manufacturers in the United Kingdom, the United States, Australia, Canada, and other countries are supplying pressurized products contained and transported in gas cylinders. These products are liquids or solids such as adhesives, coatings, and cleaners combined with a gas or gas mixture in pressure receptacles under sufficient pressure to expel the contents. These mixtures are typically expelled from the pressurized cylinders as foams, streams, or thick sprays.

Currently the HMR does not address liquids or solids transported under pressure. A typical product that would meet this description is a combination of a propellant (gas phase) and a liquid or solid component. Accordingly, the term liquefied gas does not correctly identify the contents of the container, nor can the material accurately be described by the name of the gas or liquid/solid component alone.

The new entries (UN numbers) and corresponding provisions for “chemical under pressure” address their unique characteristics and ensure the safe transport of such materials. These entries and corresponding requirements were adopted into the 17th Revised Edition of the UN Model Regulations. Subsequently, ICAO and IMO adopted the entries for chemicals under pressure as well as modal-specific requirements.

In this NPRM, PHMSA is proposing to revise the HMT to include individual entries for chemical under pressure and incorporate other safety requirements including, but not limited to, quantity and filling limits and packaging and segregation requirements.

Hazardous Materials Table (HMT)

In this NPRM, PHMSA proposes amendments to the HMT to add, revise, or remove certain proper shipping names, hazard classes, packing groups, special provisions, packaging authorizations, bulk packaging requirements, and passenger and cargo aircraft maximum quantity limits. In addition, PHMSA is proposing to comprehensively revise vessel stowage requirements to align with recent changes adopted into the IMDG Code.

Incorporation by Reference

In this NPRM, PHMSA proposes to incorporate by reference the latest editions of various international transport standards including the 2013-2014 ICAO Technical Instructions, Amendment 36-12 of the IMDG Code, and the 17th Revised Edition of the UN Model Regulations. Additionally, we are proposing to update our incorporation by reference of the Canadian Transportation of Dangerous Goods Regulations to include Amendment 8 (SOR/2011-239) dated November 9, 2011; Amendment 9 (SOR/2011-60) dated March 16, 2011; and Amendment 10 (SOR/2011-210) dated October 12, 2011. This incorporation by reference augments the broad reciprocity provided in § 171.12 where the HMR allow the use of the Canadian TDG Regulations under certain conditions when transporting hazardous materials to or from Canada by highway or rail. Finally, PHMSA is proposing the incorporation by reference of new and updated International Standards Organization (ISO) standards.

Flexible Bulk Containers (FBCs)

In this NPRM, PHMSA proposes to incorporate a new packaging definition, operational controls, performance-oriented standards, and testing requirements for Flexible Bulk Containers (FBCs). FBCs are flexible bulk packages with a capacity over the currently authorized maximum volumetric capacity for flexible IBCs, but not exceeding 15 cubic meters. FBCs provide shippers the opportunity to utilize a reusable flexible packaging for bulk shipments of certain low-hazard commodities, all of which are currently authorized in non-specification bulk bins.

The 17th Revised Edition of the UN Model Regulations adopted a performance-oriented standard for flexible bulk container design and testing. PHMSA proposes to harmonize with the internationally recognized definition of FBCs, adopt the same performance-oriented packaging design and testing standards for FBCs, and impose similar operational controls on the use of FBCs in transport. The applicable proposed definitions, operational controls, performance-oriented standards, and testing requirements will be discussed in further detail in the section by section review portion of this NPRM.

Explosive Definitions

In this NPRM, PHMSA proposes modifying the definitions for “Articles, explosive, extremely insensitive (Articles, EEI)” and “Cartridges, blank.” We also propose to replace the definition for “Explosive, extremely insensitive detonating substances (EIDS)” with a new definition for “Explosive, extremely insensitive substances (EIS).” Finally, we propose to add a definition for “Auxiliary explosive component, isolated.” The addition and modification of these definitions will provide consistency with international regulations and clarity when utilizing the UN test series 7 for explosive classification.

Packaging Authorizations

Part 173 of the HMR describes the general requirements for shipments and packagings of hazardous materials. Consistent with amendments adopted by the UN Model Regulations, PHMSA proposes to amend various Part 173 packaging requirements to authorize more flexibility when selecting packagings for hazardous materials. These proposed amendments include, but are not limited to, the authorization to use wood as a material of package construction for certain explosives, the authorization to use metals other than steel or aluminum for boxes and drums for certain hazardous materials, and the incorporation of authorizations and specifications for FBCs.

Vessel Stowage Requirements

The requirements for vessel stowage are described and specified in § 172.101(k) and HMT entries are assigned appropriate vessel stowage codes and stowage special provisions in column (10) of the HMT. Column (10) is divided into two columns: column (10A) [Vessel stowage] specifies the authorized stowage locations on board cargo and passenger vessels and column (10B) [Other provisions] specifies special stowage and segregation provisions.

In this NPRM, we are proposing to clarify these instructions by revising the vessel stowage location requirements for explosives and reducing the number of explosive stowage categories from 15 to 5 in column (10A) of the HMT. Specifically, explosive stowage categories 6 through 15 will be eliminated, and stowage categories 1 through 5 will be retained and modified. This consolidation of codes is proposed to eliminate redundant codes, align with modifications to the IMDG Code, and simplify the vessel stowage requirements by limiting the number of stowage options without compromising safety.

In addition to the HMT changes related to explosives stowage, in this NPRM PHMSA is proposing modifications to the vessel stowage provisions listed in column (10B) of the HMT. For harmonization with the IMDG Code, PHMSA proposes to incorporate the addition of a new definition for protected from sources of heat and potential or possible sources of ignition (see Section 176.2 of this NPRM for definitions), and subsequently revise and delete various vessel stowage provisions. These changes were developed to eliminate redundant codes, align with revisions to the IMDG Code, and simplify the vessel stowage requirements. By limiting the number of stowage options, we believe it will substantially reduce the complexity of the regulations without compromising safety.

The revisions and consolidations of vessel storage codes in column (10A) and the stowage provisions in (10B) of the HMT are discussed in further detail below. PHMSA believes these changes will greatly simplify vessel stowage requirements and facilitate the seamless international transport of hazardous materials by aligning with the IMDG Code.

Mercury

Consistent with the various international standards, PHMSA is proposing to add an internationally recognized proper shipping name and identification number for UN3506, Mercury contained in manufactured articles, and the addition of a Division 6.1 (toxic) subsidiary hazard risk to UN2809, Mercury. Data presented to the UN Committee of Experts on the Transport of Dangerous Goods (UNSCOE) in the last biennium indicated the need for assigning a subsidiary risk of Division 6.1 to UN2809, Mercury, and the need to adopt a separate description for UN3506, Mercury contained in manufactured articles.

IV. Amendments Not Being Considered for Adoption in This NPRM Back to Top

This NPRM proposes changes to the HMR based on amendments adopted in the 17th Revised Edition of the UN Model Regulations, the 2013-2014 edition of the ICAO Technical Instructions, and Amendment 36-12 to the IMDG Code. We are not, however, proposing to adopt all the amendments made to the various international standards into the HMR.

In many cases, amendments to the international recommendations and regulations have not been adopted because the framework or structure of the HMR makes adoption unnecessary. In other cases, we have addressed, or will address, the amendments in separate rulemaking proceedings. If we have inadvertently omitted an amendment in this NPRM, we will attempt to include the omission in the final rule. However, our ability to make changes in a final rule is limited by requirements of the Administrative Procedure Act (5 U.S.C. 553). In some instances, we can adopt a provision inadvertently omitted in the NPRM if it is clearly within the scope of changes proposed in the notice. Otherwise, in order to provide opportunity for notice and comment, the change must first be proposed in an NPRM.

One of the goals of this rulemaking is to continue to maintain consistency between the HMR and the international requirements. We are not striving to make the HMR identical to the international regulations but rather to remove or avoid potential barriers to international transportation.

The following is a list of significant amendments to the international regulations that we are not proposing to adopt in this NPRM, with a brief explanation of why the amendment was not included:

Security Provisions for High Consequence Dangerous Goods

The 17th Revised Edition of the UN Model Regulations adopted modifications to the security provisions specified in Chapter 1.4 with regard to “high consequence dangerous goods.” Specifically, these changes address the handling of certain Class 7 radioactive materials. In the 17th Revised Edition the UN adopted a list of transport security thresholds for specific radionuclides in Table 1.4.2 of Chapter 1.4. Materials identified in this table exceeding the transport security thresholds indicated in terabecquerels (TBq) would be subject to additional security requirements such as security training and security plans.

In this NPRM, PHMSA is not proposing the adoption of the changes to the security requirements found in the HMR with regard to high consequence dangerous goods. These amendments to the international recommendations and regulations are not being adopted because the existing safety and security requirements found in Subpart I of Part 172 are consistent with and provide for a level of safety and security equivalent to the revised UN Model Regulations.

Requirements for Lithium Batteries

On January 11, 2010, PHMSA published an NPRM in the Federal Register under Docket HM-224F (75 FR 1302). The NPRM included provisions to ensure lithium batteries are properly packaged to reduce the possibility of damage that could lead to a catastrophic incident, and minimize the consequences of an incident should one occur. In addition, PHMSA proposed to require lithium battery shipments to be accompanied by hazard communication that ensures appropriate and careful handling by air carrier personnel, including the flight crew, and informs both transport workers and emergency response personnel of actions to be taken in an emergency.

Subsequently, on April 11, 2012, PHMSA published a notice in the Federal Register requesting additional comment on the impacts of changes to the requirements for the air transport of lithium cells and batteries that were adopted into the 2013-2014 ICAO Technical Instructions. PHMSA is considering whether to harmonize the HMR with these requirements, and published a notice to allow interested persons an opportunity to supplement comments to the HM-224F NPRM.

The HM-224F NPRM and the April 11, 2012 notice, which PHMSA developed in close coordination with the Federal Aviation Administration (FAA), are the latest in a series of actions PHMSA has taken to address the potential risks posed by lithium batteries in transportation. These publications solicit comments on revisions to the HMR and are based on lithium battery provisions in the 16th Revised Edition of the UN Model Regulations and the 2013-2014 ICAO Technical Instructions. Because lithium batteries are addressed in separate battery-specific rulemakings and notices, PHMSA is not proposing amendments pertaining to the transportation of lithium cells and batteries in this NPRM. The docket for the lithium battery rulemaking can be found at http://www.regulations.gov under PHMSA-2009-0095.

Notification to the Pilot-In-Command

Section 175.33 of the HMR addresses the requirements for notification of pilot-in-command regarding hazardous materials stowed aboard the aircraft. Recent amendments adopted in the upcoming 2013-2014 edition of the ICAO Technical Instructions modify the information required to be given to the pilot-in-command as prescribed in Part 7; 4.1. These modifications include a requirement that the operator of an aircraft transporting hazardous materials provide personnel with responsibilities for operational control of the aircraft with the same information that is required to be provided to the pilot-in-command. In addition, the modifications also include a table of hazardous materials not required to appear on the notification provided to the pilot-in-command. Because better analysis is necessary to assess the regulatory impact of alignment with the ICAO Technical Instructions on this matter, PHMSA is not proposing to adopt the new provisions in this NPRM. However, PHMSA does intend to address these changes in a future rulemaking.

Requirements for Salvage Pressure Receptacles

The 17th Revised Edition of the UN Model Regulations adopted guidelines for Competent Authorities to use when issuing approvals for salvage pressure receptacles. These revisions are found in Chapter 1.2, 4.1, 5.4, and 6.2 of the UN Model Regulations. Specifically, these requirements address the packaging, hazard communication, and safe transport of salvage pressure receptacles, also known as salvage cylinders in the United States.

The HMR currently address the packaging, hazard communication, and safe transport of salvage cylinders in § 173.3(d) and do not require approval of the Associate Administrator to do so. PHMSA believes the current salvage cylinder requirements in the HMR provide a sufficient level of safety and adequately address the shipment of damaged and defective cylinders. Therefore, PHMSA is not proposing changes to the current HMR provisions for salvage cylinders in this NPRM.

Fireworks Classification Reference

The 17th Revised Edition of the UN Model Regulations adopted requirements for fireworks classification references. Specifically, a provision was adopted requiring fireworks under identification numbers UN0333, UN0334, UN0335, UN0336, and UN0337, having been approved by a competent authority, to bear a classification reference on the shipping paper. The classification reference would indicate the country of the competent authority approval and would also include a unique serial reference for the specific firework device.

PHMSA intends to address fireworks-related issues in a separate rulemaking and, therefore, will not address fireworks-related issues in this NPRM. The docket for the fireworks rulemaking can be found at http://www.regulations.gov under PHMSA-2010-0320 (HM-257).

Criteria for Exclusion From Class 1

The ICAO and IMO recently adopted guidance issued to competent authorities regarding when an article or substance can be excluded from meeting the classification of a Class 1 (explosive) material. PHMSA is not adopting the issued guidance in this NPRM because it is classification parameters to be considered by a competent authority and not actual regulatory provisions.

Air Bag Inflator, Air Bag Module, or Seat-Belt Pretensioner Revisions

The 17th Revised Edition of the UN Model Regulations revised the authorized packagings used for the transportation of air bag inflators, air bag modules, or seat-belt pretensioners. Specifically, in addition to currently authorized packagings, the UN Model Regulations adopted authorizations for 1N2 and 1D drums, 3B2 jerricans, and 4A, 4B, 4N, and 4H1 boxes.

PHMSA is not addressing the additional packaging authorizations in this rulemaking as these and other related issues were addressed in a separate NPRM. The docket for the air bag inflator, air bag module, and seat-belt pretensioner rulemaking can be found at http://www.regulations.gov under PHMSA-2010-0201.

Pressure Relief Valves for Closed Cryogenic Receptacles

A new provision was added to Packing Instruction P203 of the 17th Revised Edition of the UN Model Regulations. The amendment prescribes that the frequency of periodic inspection and test of the pressure relief valves for closed cryogenic receptacles shall not exceed five years.

In this NPRM, PHMSA is not proposing to adopt this amendment. Section 173.316, “Cryogenic Liquids in Cylinders,” and § 173.301, “General Requirements for Shipment of Compressed Gases and Other Hazardous Materials in Cylinders, UN Pressure Receptacles and Spherical Pressure Vessels” do not specify the frequency of tests of pressure relief device systems. The HMR requires testing of these systems in accordance with the Compressed Gas Association's S-1.1, “Pressure Relief Device Standards—Part 1—Cylinders for Compressed Gases” and S-7, “Method for Selecting Pressure Relief Devices for Compressed Gas Mixtures in Cylinders.” PHMSA believes these requirements already provide for an adequate level of safety of pressure relief device systems.

Absorbent Materials for Air Packaging

Numerous packing instructions of the ICAO Technical Instructions were revised to consistently provide that for certain liquid hazardous materials, inner packagings must be packed with sufficient absorbent material to absorb the entire contents of the inner packagings.

PHMSA does not intend to adopt these amendments in this NPRM. Rather, we adopted them in a separate rulemaking under docket PHMSA-2007-29364 (HM-231A). For example, in the final rule published in the Federal Register on April 16, 2012 (77 FR 22504), we revised § 173.27(e) to require that inner packagings be packaged in a rigid leakproof liner or rigid intermediate packaging containing sufficient absorbent material to absorb the entire contents of the inner packaging before being placed in its outer package when absorbent material was required. Generally, this requirement is applicable to Packing Group I liquids.

UN Test Series 6(d) for Certain Division 1.4S Articles

Special provision 364 was added to the 17th Revised Edition of the UN Model Regulations that requires limited quantity packages of certain Division 1.4S explosives under the following descriptions “UN 0012 Cartridges for weapons, inert projectile or Cartridges, small arms,” “UN0014 Cartridges for weapons, blank or Cartridges, small arms, blank or Cartridges for tools, blank,” and “UN0055 Cases, cartridge, empty with primer” be capable of passing Test Series 6(d) in accordance with the UN Manual of Tests and Criteria as determined by the competent authority.

PHMSA believes that the current requirements for shipments of these articles adequately address the hazards associated with the transport of these limited quantity hazardous materials and, thus, will not be adopting the requirement for these materials as packaged to be capable of passing Test Series 6(d) of Part I of the UN Manual of Tests and Criteria.

Coolants, Conditioners, and Asphyxiates

In many instances cargo transport units are treated with substances to cool and condition the transport environment inside the transport unit. Occasionally gases presenting a risk of asphyxiation are used as part of this cooling and conditioning process. In this case an accumulation of these gases may present a risk to those handling these cargo transport units in transport.

The 17th Revised Edition of the UN Model Regulations adopted various requirements applicable to packages and cargo transport units containing substances presenting a risk of asphyxiation when used for cooling or conditioning purposes. Requirements adopted internationally include a new marking requirement for both packages and freight containers containing dangerous goods used for cooling and conditioning as well as the requirement to note that a dangerous good is being used as a coolant or conditioner on transport documents. PHMSA believes that the current requirements for shipments of dry ice and other potential coolants adequately address the hazards associated with the use of these hazardous materials as coolants or conditioners and notes that the current provisions of the HMR would not preclude the use of the new marking for domestic or international transport.

V. Section-By-Section Review Back to Top

The following is a section-by-section review of the amendments proposed in this NPRM:

Part 171 Back to Top

Section 171.7

The “National Technology Transfer and Advancement Act of 1996” directs agencies to use voluntary consensus standards. According to the Office of Management and Budget (OMB), Circular A-119, “Federal Participation in the Development and Use of Voluntary Consensus Standards and in Conformity Assessment Activities,” government agencies must use voluntary consensus standards wherever practical in the development of regulations. Agency adoption of industry standards promotes productivity and efficiency in government and industry, expands opportunities for international trade, conserves resources, improves health and safety, and protects the environment.

To these ends, PHMSA actively participates in the development and updating of consensus standards through representation on more than 20 consensus standard bodies. PHMSA regularly reviews updated consensus standards and considers their merit for inclusion in the HMR.

Section 171.7 provides a listing of all standards incorporated by reference into the HMR. For this rulemaking, we evaluated updated international consensus standards pertaining to proper shipping names, hazard classes, packing groups, special provisions, packaging authorizations, air transport quantity limitations, and vessel stowage requirements and determined that the revised standards provide an enhanced level of safety without imposing significant compliance burdens. These standards have a well-established and documented safety history; their adoption will maintain the high safety standard currently achieved under the HMR. Therefore, we propose to update by adding and revising the incorporation by reference materials under the following organizations:

The International Civil Aviation Organization (ICAO) Technical Instructions for the Safe Transport of Dangerous Goods by Air, 2011-2012 Edition is revised to incorporate the 2013-2014 Edition.

The International Convention for the Safety of Life at Sea (SOLAS) Amendments 2002, Chapter II-2/Regulation 19, Consolidated Edition 2004 is revised to incorporate the 2009 Consolidated Edition.

The International Maritime Organization (IMO) International Maritime Dangerous Goods Code, 2010 Edition, Incorporating Amendment 35-10, English Edition, Volumes 1 and 2 is revised to incorporate the 2012 Edition, Amendment 36-12.

The International Organization for Standardization (ISO) entries for “ISO 10156:1996, Gases and Gas Mixtures—Determination of fire potential and oxidizing ability for the selection of cylinder valve outlets, Second edition, February 1996 (E)” and “ISO 10156-2:2005, Gas cylinders—Gases and gas mixtures—Part 2: Determination of oxidizing ability of toxic and corrosive gases and gas mixtures, First edition, August 2005, (E)” are removed and replaced with entry for “ISO 10156:2010: Gases and gas mixtures—Determination of fire potential and oxidizing ability for the selection of cylinder valve outlets, Third edition, March 2010.”

The entry “ISO 4126-1: Safety valves—Part 1: General requirements, December 15, 1991, First edition” is revised as the entry “ISO 4126-1: Safety valves—Part 1: General requirements/Cor 1, August 2, 2007, Second edition.” The entry “ISO 11117, Gas cylinders—Valve protection caps and valve guards for industrial and medical gas cylinders—Design, construction and tests, First edition, August 1998, (E)” is revised as the entry “ISO 11117:2008/Cor 1:2009 Gas cylinders—Valve protection caps and valve guards—Design, construction and tests, May 5, 2009, Second edition”.

The entries “ISO 4126-7: Safety valves—Part 7: Common data/Cor 1, October 23, 2006, First edition,” and “ISO 13340 Transportable gas cylinders—Cylinders valves for non-refillable cylinders—Specification and prototype testing, April 5, 2001, First edition” are added.

The Transport Canada entry, Transportation of Dangerous Goods Regulations, including Clear Language Amendments 1 through 7 is revised to include Amendments 8, 9 and 10.

The United Nations Recommendations on the Transport of Dangerous Goods—Model Regulations, 16th Revised Edition (2009), Volumes I and II, is revised to incorporate the 17th Revised Edition (2011), Volumes I and II.

The United Nations Recommendations on the Transport of Dangerous Goods—Manual of Tests and Criteria, Fifth Revised Edition (2009), is revised to incorporate Amendment 1 (2011).

Section 171.8

This section defines terms generally used throughout the HMR that have broad or multi-modal applicability. PHMSA is proposing to add the following defined term based on its adoption in the 17th Revised Edition of the UN Model Regulations: Flexible Bulk Container (FBC): This term means a flexible container with a capacity not exceeding 15 cubic meters and includes liners and attached handling devices and service equipment.

Currently the HMR do not prescribe requirements for the transport of FBCs. In this NPRM, PHMSA is proposing to adopt various transportation and manufacturing requirements for FBCs. Prior to adoption of such standards, the term “Flexible Bulk Container” must be defined. Therefore in this NPRM we are proposing to adopt the above definition of an FBC based on the definition for FBC adopted in the IMDG Code and 17th Revised Edition of the UN Model Regulations.

Part 172 Back to Top

Section 172.101

Section 172.101 provides instructions for using the Hazardous Materials Table (HMT) and the HMT itself. In this NPRM, PHMSA is proposing to revise the instructional text that precedes the HMT.

Paragraph (c) of § 172.101 describes the information indicated in column 2 of the HMT. Column 2 lists the hazardous materials descriptions and proper shipping names of materials designated as hazardous materials. Paragraph (c)(10) of § 172.101 prescribes how mixtures or solutions not identified specifically by name are described.

In this NPRM, PHMSA proposes to revise § 172.101(c)(10) to incorporate language adopted in the 17th Revised Edition of the UN Model Regulations that states mixtures and solutions must meet the definition of one or more hazard class to be classified as a hazardous material. This change will clarify that for a mixture or solution composed of one or more components that are classified as a hazardous material, the resulting mixture or solution must meet the definition of one or more hazard classes to be classified as a hazardous material.

Paragraph (k) of § 172.101 explains the purpose of column (10) of the HMT and prescribes the vessel stowage and segregation requirements for specific entries in the HMT. Column (10) is divided into two columns: column (10A) [Vessel stowage] specifies the authorized stowage locations on board cargo and passenger vessels and column (10B) [Other provisions] specifies special stowage and segregation provisions.

In this NPRM, we are proposing to modify these instructions by revising the vessel stowage location requirements for explosives and reducing the number of explosive stowage categories from 15 to 5. Specifically, the explosive stowage categories 6 through 15 will be eliminated and stowage categories 1 through 5 will be modified. Changes to the explosive stowage categories are necessary because, as part of this NPRM, PHMSA proposes to remove magazine stowage Types “A,” “C,” and special stowage from Part 176 with the consolidation of authorized explosive stowage categories. The authorized explosive stowage categories will be replaced with a new term of art “Closed cargo transport units for Class 1 (explosives).” Included in this definition are freight containers or transport vehicles that are structurally serviceable in accordance with § 176.172, portable magazines conforming to § 176.137, and small vessel compartments (i.e., mast lockers and deck house). These changes will require Class 1 materials to be shipped in closed cargo transport units as defined above when stowed on deck.

Hazardous Materials Table (HMT)

In this NPRM, PHMSA is proposing to amend the HMT. Readers should review all changes for a complete understanding of the amendments. For purposes of the Government Printing Office's typesetting procedures, proposed changes to the HMT appear under three sections of the Table, “remove,” “add,” and “revise.” Certain entries in the HMT, such as those with revisions to the proper shipping names, appear as a “remove” and “add.” Proposed amendments to the HMT include the following:

New HMT entries

UN3497Krill meal

UN3498Iodine monochloride, liquid

This new HMT entry is a result of the division of the proper shipping name Iodine monochloride into two authorized proper shipping names; one for the liquid state of the commodity and another for the solid state. Solid shipments of Iodine monochloride remain assigned to UN1792.

UN3499Capacitor, electric double layer (with an energy storage capacity greater than 0.3 Wh)

This new HMT entry is intended to cover capacitors with an energy storage capacity greater than 0.3 Wh. Capacitors are assigned as a Class 9 miscellaneous hazardous material and measures required to prevent short circuit are provided in special provision 361.

UN3500Chemical under pressure, n.o.s.

UN3501Chemical under pressure, flammable, n.o.s.

UN3502Chemical under pressure, toxic, n.o.s.

UN3503Chemical under pressure, corrosive, n.o.s.

UN3504Chemical under pressure, flammable, toxic, n.o.s.

UN3505Chemical under pressure, flammable, corrosive, n.o.s.

The “Chemical under pressure. n.o.s.” HMT entries are added to address shipments of liquids or solids (e.g., adhesives, coatings, and cleaners) combined with a gas or gas mixtures utilized to expel the contents from pressure vessels. The primary hazard class for these shipments is determined by the hazard presented by the propellant and any subsidiary risk is determined by the properties of the liquid or solid under pressure. Toxic gases are not permitted as propellants.

UN3506Mercury contained in manufactured articles

This new entry was created to separately address manufactured articles containing mercury. The international community provided an exception from regulation for instruments and articles containing not more than 1 kg of mercury, when transported by means other than aircraft. PHMSA is unable to adopt a comparable exception as the reportable quantity for mercury is 0.454 kg (1.00 lbs.), but does propose to revise the current exception authorized in § 173.164(e) for shipments containing less than 0.454 kg (1.00 pound) to include transportation by vessel.

Removed HMT Entries

UN3492Toxic by inhalation liquid, corrosive, flammable, 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 LC50

UN3493Toxic by inhalation liquid, corrosive, flammable, 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 LC50

These entries are proposed for removal from the HMT due to their similarity to UN3488 and UN3489 respectfully. The sole difference between these entries is the order of subsidiary risks, which does not affect the classification and transport conditions applied to shipments of these substances. As a result, PHMSA proposes to remove identification numbers UN3492 and UN3493 to avoid confusing shippers in determining which identification numbers to use.

Amendments to the Column (1) Symbols

Section 172.101(b) describes column (1) of the HMT and the associated symbols that may be indicated in the column. In accordance with § 172.101(b), the symbol “G” identifies proper shipping names for which one or more technical names of the hazardous material must be entered in parentheses in association with the basic description on a shipping paper. In this NPRM, PHMSA proposes to add a “G” to column (1) for “UN1707, Thallium compounds, n.o.s.” The addition of a “G” to this entry will provide notification of the technical name of this toxic material and thus aid emergency responders with providing an appropriate response.

Amendments to the Column (2) Hazardous Materials Descriptions and Proper Shipping Names

Section 172.101(c) describes column (2) of the HMT and the requirements for hazardous materials descriptions and proper shipping names. Among other requirements, in accordance with § 172.101(c)(1), proper shipping names indicated in column (2) of the HMT may be used in the singular or the plural form interchangeably. Regardless, in this NPRM, PHMSA is revising several entries in the HMT to remove the plural ending letter “s” to provide continuity with the internationally accepted proper shipping names. Specifically, PHMSA proposes to remove the letter “s” from: UN1107, Amyl chlorides; UN1111, Amyl mercaptans; UN1113, Amyl nitrites; and, UN2347, Butyl Mercaptans.

Generally the physical state (solid or liquid) appears before the hazard characteristics (toxic, flammable, etc.) in the sequence of wording used in proper shipping names specified in column (2) of the HMT. In some instances, the hazard characteristics are indicated before the physical state. In this NPRM, PHMSA is proposing changes to several proper shipping names to indicate the physical state before the hazard characteristics for consistency in formatting.

Current proper shipping names:

UN No. Proper shipping name
3276 Nitriles, toxic, liquid, n.o.s.
3278 Organophosphorus compound, toxic, liquid, n.o.s.
3282 Organometallic compound, toxic, liquid, n.o.s.
3439 Nitriles, toxic, solid, n.o.s.
3464 Organophosphorus compound, toxic, solid, n.o.s.
3467 Organometallic compound, toxic, solid, n.o.s.

Proposed proper shipping names:

UN No. Proper shipping name
3276 Nitriles, liquid, toxic, n.o.s.
3278 Organophosphorus compound, liquid, toxic, n.o.s.
3282 Organometallic compound, liquid, toxic, n.o.s.
3439 Nitriles, solid, toxic, n.o.s.
3464 Organophosphorus compound, solid, toxic, n.o.s.
3467 Organometallic compound, solid, toxic, n.o.s.

Currently, the HMT includes the entry “Toxic, liquids, organic, n.o.s., UN2810” with the proper shipping name indicated in column (2) that includes a comma between the words “toxic” and “liquid.” This is not consistent with the UN Model Regulations, the ICAO Technical Instructions, or the IMDG Code as there is no comma between the words “Toxic” and “liquid.” PHMSA proposes to revise this entry by removing the comma for consistency with international standards and regulations and to provide shippers with the most appropriate shipping description.

A new proper shipping name “Cartridges for tools, blank” is proposed to be assigned to identification number UN0014. This proper shipping name more appropriately describes industrial blank cartridges currently described as “UN0323, Cartridges, power device” or “ORM-D or ORM-D-AIR, Cartridges, power device (used to project fastening devices).” In this NPRM, PHMSA is proposing to remove the “ORM-D” entry for “Cartridges, power device (used to project fastening devices)” as the proper shipping name for such articles is now “Cartridges for tools, blank” under identification number UN0014. Subsequent changes will be made to § 173.63 and the § 172.102(c)(1) special provision 347 to replace any references to “ORM-D or ORM-D-AIR, Cartridges, power device (used to project fastening devices)” with the new description “UN0014, Cartridges for tools, blank (used to project fastening devices).” Additionally, such articles are not subject to the UN Test Series 6(d) previously required under special provision 347. The description “UN0323, Cartridges, power device” will remain subject to special provision 347.

The proper shipping name for “UN1305, Vinyltrichlorosilane, stabilized” is amended by removing the term “stabilized” for consistency with the Dangerous Goods Lists of the various international standards and the HMT of the HMR. The proposed proper shipping name for UN1305 is “Vinyltrichlorosilane.”

The 17th Revised Edition of the UN Model Regulations modified the qualifying text (text in italics) for UN Nos. 3381-3390 and UN Nos. 3488-3491. The proposed changes to these entries' qualifying or modifying text in italics would change the wording from “with an inhalation toxicity lower than or equal to” to “with an LC50 lower than or equal to”. The intent of this terminology change is to better identify the criteria used to determine the proper classification of these substances.

The entry “Formaldehyde solutions (with not less than 10% and less than 25% formaldehyde), see Aviation regulated liquid, n.o.s. or Other regulated substances, liquid, n.o.s.” appears in column (1) of the HMT. PHMSA proposes to revise this entry by placing it into the correct column (2) of the HMT. This is an editorial revision and simply corrects an unintended error in the HMT.

Amendments to the Column (4) identification numbers

Section 172.101(e) describes Column (4) of the HMT and the designation of the identification number to each proper shipping name. With the proposed addition of a separate identification number (UN3506) for the description “Mercury contained in manufactured articles,” PHMSA proposes to remove the description that is currently assigned to “UN2809, Mercury.”

Amendments to the Column (6) label(s)

Section 172.101(g) describes Column (6) of the HMT and the labels required (primary and subsidiary) for specific entries in the HMT. Data presented to the UN Committee of Experts on the Transport of Dangerous Goods in this last biennium indicated a need for the addition of subsidiary risk of Division 6.1 (toxic) to be assigned to “UN2809, Mercury” and to the new entry “UN3506, Mercury contained in manufactured articles.” We note that for air transport, Special provision A192 provides relief from the labeling and documentation requirements of this new subsidiary risk. [1]

In addition to the changes above, data was also presented to the UN Committee of Experts on the Transport of Dangerous Goods that indicated the need for a subsidiary risk of Division 6.1 (toxic) to be assigned to UN2381 Dimethyl disulfide.

PHMSA proposes to make appropriate amendments to the HMT to account for these revisions to the UN Model Regulations.

Amendments to the Column (7) Special Provisions

Section 172.101(h) describes Column (7) of the HMT and the § 172.102(c) Special provisions assigned to specific entries in the HMT. The particular modifications to the entries in the HMT are discussed below. See Section 172.102 special provisions for a detailed discussion of the proposed additions, revisions, and deletions to the special provisions addressed in this NPRM.

Several HMT entries are revised to include bulk special provision B120. Special provision B120 indicates that the material, when offered in conformance with the applicable requirements of Part 178 and general packaging requirements in Part 173, may be offered for transportation in a Flexible Bulk Container. See Section 172.102 special provisions for a detailed discussion of our proposed addition of special provision B120.

In this NPRM, special provision B120 is proposed to be assigned to the following entries:

Proper shipping name UN No.
Naphthalene, crude or Naphthalene, refined UN1334
Sulfur (domestic and international entries) UN1350
Calcium nitrate UN1454
Magnesium nitrate UN1474
Potassium nitrate UN1486
Sodium nitrate UN1498
Sodium nitrate and potassium nitrate mixtures UN1499
Ammonium nitrate, with not more than 0.2% total combustible material, including any organic substance, calculated as carbon to the exclusion of any other added substance UN1942
Ammonium nitrate based fertilizer UN2067
Paraformaldehyde UN2213
Environmentally hazardous substance, solid, n.o.s UN3077
Sodium perborate monohydrate UN3377
Sodium carbonate peroxyhydrate UN3378

In this NPRM, new special provision 363 is proposed to be assigned to the following entries:

Proper shipping name UN No.
Gas oil or Diesel fuel or Heating oil, light UN1202
Gasoline includes gasoline mixed with ethyl alcohol, with not more than 10% alcohol UN1203
Kerosene UN1223
Petroleum distillates, n.o.s. or Petroleum products, n.o.s UN1268
Fuel, aviation, turbine engine UN1863
Ethanol and gasoline mixture or Ethanol and motor spirit mixture or Ethanol and petrol mixture, with more than 10% ethanol UN3475

See Section 172.102 special provisions for a detailed discussion of our proposed addition of special provision 363.

The entry for UN1008 Boron trifluoride is assigned new special provision 238. See Section 172.102 Special provisions for a detailed discussion of our proposed addition of special provision 238.

With the addition of a Division 6.1 (toxic) subsidiary risk to “UN2381, Dimethyl disulfide,” the portable tank codes and portable tank provisions are proposed to be revised as follows:

T4 is replaced by T7

TP1 is replaced by TP2, TP13, and TP39

See Section 172.102 Special provisions for a detailed discussion of our proposed addition of special provision TP39.

Review of the “Guiding Principles for the Development of the UN Model Regulations (Guiding Principles)” indicates that in some cases, the portable tank instructions for the transport of Division 4.3 liquid materials are not consistent with the Guiding Principles, and, in other instances, relevant portable tank special provisions were missing or incorrectly assigned. The following changes are proposed with deletions indicated by a strikethrough and additions or replacements shown in bold font.

See Section 172.102 Special provisions for a detailed discussion of our proposed addition of special provision TP41.

Special provisions A100 and A103 are revised to clarify that the weight (mass) limitations specified are net and not gross amounts for secondary lithium batteries. See Section 172.102 Special provisions for a detailed discussion of our proposed revision of special provisions A100 and A103.

Special provision A192 is added to note that regardless of the Division 6.1 (toxic) subsidiary risk indicated in the HMT, the toxic subsidiary risk label and an indication of the subsidiary risk on the shipping paper are not required for manufactured articles containing less than 0.454 kg (1.00 pound) of mercury. This special provision is assigned to the entry “UN3506, Mercury contained in manufactured articles.”

Special provision A200 is added to require that certain articles may not be transported in passenger baggage and are to be shipped as cargo when transported via aircraft. Under certain circumstances, the articles affected by this special provision may be excepted from the requirements of the HMR. When these articles are not subject to the regulations, there is the potential for them to be inappropriately carried aboard an aircraft. In response to this safety concern, the ICAO Technical Instructions were revised to clarify that when transported by aircraft, these articles, regardless of whether they are otherwise excepted from the regulations, must be transported as cargo and may not be carried onboard an aircraft by passengers or crewmembers in carry-on baggage, checked baggage, or on their person unless specifically excepted by § 175.10, “Exceptions for Passengers, Crewmembers, and Air Operators.” Consistent with the revised ICAO Technical Instructions requirement, PHMSA proposes to adopt the special provision restricting these items from being carried aboard an aircraft by passengers and crewmembers.

This special provision is assigned to the following entries: “UN3166, Engines, internal combustion or Engines, fuel cell, flammable gas powered”;“UN3166, Engines, internal combustion or Engines, fuel cell, flammable liquid powered”;“UN3166, Vehicle, flammable gas powered or Vehicle, fuel cell, flammable gas powered”;“UN3166, Vehicle, flammable liquid powered or Vehicle, fuel cell, flammable liquid powered”;“UN0503, Air bag inflators or Air bag modules or Seat-belt pretensioners”; and “UN3268, Air bag inflators or Air bag modules or Seat-belt pretensioners.”

Special provision W10 is assigned to “UN3486, Calcium hypochlorite mixture, dry, corrosive with more than 10% but not more than 39% available chlorine” and to “UN2208, Calcium hypochlorite mixtures, dry, with more than 10 percent but not more than 39 percent available chlorine.” Special provision W10 indicates that, when offered for transportation by vessel, these entries may not be offered in Large Packagings. See Section 172.102 Special provisions for a detailed discussion of our proposed addition of special provision W10.

Amendments to the Column (9) quantity limitations

Section 172.101(j) describes Column (9) of the HMT and the quantity limitations for specific entries in the HMT. Furthermore, Columns (9A) and (9B) specify the maximum quantities that may be offered for transportation in one package by passenger-carrying aircraft or passenger-carrying rail car (Column (9A)) or by cargo-only aircraft (Column (9B)). Unless otherwise indicated the quantity limitations shown in column (9) of the HMT are net. PHMSA proposes to remove the gross weight indicator in columns (9A) (if authorized previously) and (9B) for the following battery entries. The quantity limit for these entries should be based on the weight of the battery or batteries and not the weight of the battery or batteries plus the packaging (i.e., the package).

UN3028 Batteries, dry, containing potassium hydroxide solid, electric, storage

UN2794 Batteries, wet, filled with acid, electric storage

UN2795 Batteries, wet, filled with alkali, electric storage

UN3468 Hydrogen in a metal hydride storage system or Hydrogen in a metal hydride storage system contained in equipment or Hydrogen in a metal hydride storage system packed with equipment

UN3090 Lithium battery

UN3091 Lithium batteries packed with equipment

PHMSA is proposing to revise column (9A) to forbid several entries previously authorized for shipment on passenger-carrying aircraft or passenger-carrying rail to harmonize with changes to the ICAO Technical Instructions. The following entries would now be forbidden on passenger-carrying aircraft or passenger-carrying rail.

UN1162 Dimethyldichlorosilane

UN1196 Ethyltrichlorosilane

UN1250 Methyltrichlorosilane

UN1298 Trimethylchlorosilane

UN1305 Vinyltrichlorosilane

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

UN3361 Chlorosilanes, toxic, corrosive, n.o.s.

UN3362 Chlorosilanes, toxic, corrosive, flammable, n.o.s.

Quantity limits of 450 L for “UN3334, Aviation regulated liquid, n.o.s.” and 400 kg for “UN3335, Aviation regulated solid, n.o.s.” are proposed for both columns (9A) and (9B). Previously, there was no limit to the amount authorized to be shipped in one package. These new quantity limits are consistent with authorized quantity limits found in the ICAO Technical Instructions.

Amendments to the Column (10) Vessel Stowage Requirements

Vessel Stowage Location (10A)

Section 172.101(k) explains the purpose of column (10) of the HMT and prescribes the vessel stowage and segregation requirements for specific entries in the HMT. Column (10) is divided into two columns: column (10A) [Vessel stowage] specifies the authorized stowage locations on board cargo and passenger vessels and column (10B) [Other provisions] specifies special stowage and segregation provisions.

PHMSA is proposing to simplify the number of vessel stowage locations for shipments of Class 1 explosive materials to harmonize with recently adopted vessel explosive stowage categories in the IMDG Code. Currently, there are 15 possible stowage location codes available for assignment to column (10A) for explosive shipments. Recent changes in the IMDG Code have reduced the number of available explosive stowage location codes to five. This consolidation of codes was accomplished to reduce the complexity of the regulations without compromising safety.

The International Maritime Organization (IMO) determined that the term “magazine” was no longer necessary and the magazine concept could be incorporated into a broader definition for closed cargo transport units for Class 1 (explosives) material. In general, a magazine used to store and transport explosives is equivalent to a closed cargo transport unit with a wooden floor. A magazine type A has additional wooden walls, or walls covered with wooden pallets, and is currently only assigned to 7 entries in the HMT. A magazine type C is currently defined by a minimum distance to the ship's side of 2.4 m (8 feet). Proposed requirements to load Class 1 closed cargo transport units a minimum distance of 2.4 m (8 feet) from the ship's side wall remove the need for specific stowage category references to magazine stowage type C. The IMO, taking into account the properties of various classes and divisions of explosives, has determined that only 1.4S, 1.4G, 1.4D, and 1.4C explosives are acceptable on passenger ships. PHMSA agrees. Therefore, PHMSA has removed the majority of Class 1 stowage location codes and revised the remaining codes. The codes proposed for each Class 1 entry are grouped by proposed stowage code (01, 02, 03, 04, or 05) as follows:

Proposed Explosive Stowage Category

01—means the material may be stowed “on deck” in closed cargo transport units or “under deck” on a cargo vessel (up to 12 passengers) and on a passenger vessel

02—means the material may be stowed “on deck” in closed cargo transport units or “under deck” on a cargo vessel (up to 12 passengers) and “on deck” in closed cargo transport units or “under deck” in closed cargo transport units on a passenger vessel

03—means the material may be stowed “on deck” in closed cargo transport units or “under deck” on a cargo vessel (up to 12 passengers) but the material is prohibited on a passenger vessel

04—means the material may be stowed “on deck” in closed cargo transport units or “under deck” in closed cargo transports on a cargo vessel (up to 12 passengers) but the material is prohibited on a passenger vessel

05—means the material may be stowed “on deck” in closed cargo transport units on a cargo vessel (up to 12 passengers) but the material is prohibited on a passenger vessel

Taking into account the properties of various classes and divisions of explosives, the IMO determined new stowage category assignments as follows:

Division Stowage category Division Stowage category
1.1A 05 1.4F 05
1.1B 05 1.1G 03
1.2B 05 1.2G 03
1.4B 05 1.3G 03
1.1C 04 1.4G 02
1.2C 04 1.2H 05
1.3C 04 1.3H 05
1.4C 02 1.1J 05
1.1D 04 1.2J 05
1.2D 04 1.3J 05
1.4D 02 1.2K 05
1.5D 03 1.3K 05
1.1E 04 1.1L 05
1.2E 04 1.2L 05
1.4E 03 1.3L 05
1.1F 05 1.6N 03
1.2F 05 1.4S 01
1.3F 05    

PHMSA agrees with the assignments and, in particular, agrees that only 1.4S, 1.4G, 1.4D, and 1.4C explosives are acceptable on passenger ships.

Vessel stowage codes (10B).

Section 172.101(k) describes Column (10) of the HMT and the vessel stowage requirements for specific entries in the HMT. Furthermore, column (10B) [Other provisions] specifies codes for stowage requirements for specific hazardous materials. The meaning of each code in Column (10B) is set forth in § 176.84 of this subchapter.

Vessel shipments of Class 1 explosives are currently required to be stored away from all sources of heat including steam pipes, heating coils, sparks, and flame in accordance with § 176.116(a). In addition to this general provision in § 176.116, several vessel stowage codes in column (10B) make reference to shading or stowing away from heat. To harmonize with the IMDG Code, reduce the number of redundant vessel stowage codes, and incorporate the addition of a new definition for protected from sources of heat (see Section 176.2 of this NPRM for definition) PHMSA proposes to delete vessel stowage codes 50 and 48 and replace all references to these codes with stowage code 25. See Section 176.84 for a detailed discussion of our proposed revision to stowage code 25.

The following proper shipping names and corresponding identification numbers will have stowage code 48 replaced with stowage code 25 in Column (10B) in the HMT.

Proper shipping name UN No. Proper shipping name UN No.

The following proper shipping names and corresponding identification numbers will have stowage code 19 replaced with stowage code 25 in Column (10B) in the HMT if stowage code 25 is not currently listed in Column (10B). If the proper shipping name already is currently assigned both stowage code 19 and 25; stowage code 19 will be deleted.

We also propose to assign stowage code 25 to every Class 1 explosive table entry to indicate these materials must be protected from sources of heat in accordance with the new proposed definition of “protected from sources of heat” in § 176.2. See Section 176.84 for a detailed discussion of our proposed revision to stowage code 25 and § 176.2 for the proposed definition of “protected from sources of heat.”

Stowage code 50 is currently not assigned to any HMT entries and is being proposed for deletion in this NPRM.

PHMSA proposes to revise stowage code 128 to account for a citation change in the IMDG Code. The proposed new text of stowage code 128 is “stow in accordance with the IMDG Code, Sub-section 7.6.2.7.2 (incorporated by reference; see § 171.7 of this subchapter).”

PHMSA proposes to delete stowage codes 7E, 8E, and 20E. The proposed reduction in the number of vessel stowage categories in column (10A) makes these codes unnecessary and any applicable stowage requirements are covered by the requirements of the applied code in column (10A). Consequently, we propose to remove stowage codes 7E, 8E, or 20E from the following entries, as applicable:

The following proper shipping names and corresponding identification numbers will have stowage code 7E removed from column (10B) of the HMT.

Proper shipping name UN No. Proper shipping name UN No.
Ammunition, smoke with or without burster, expelling charge or propelling charge UN0303 Ammunition, tear-producing with burster, expelling charge or propelling charge UN0301

The following proper shipping names and corresponding identification numbers will have stowage code 8E removed from column (10B) of the HMT.

Proper shipping name UN No. Proper shipping name UN No.
Ammunition smoke, white phosphorus with burster, expelling charge, or propelling charge UN0245 Articles, explosive, n.o.s UN0354
Ammunition, smoke, white phosphorus with burster, expelling charge, or propelling charge UN0246 Articles, explosive, n.o.s UN0355
Ammunition, smoke with or without burster, expelling charge or propelling charge UN0015 Articles, explosive, n.o.s UN0356

Ammunition, tear-producing with burster, expelling charge or propelling charge UN0018 Contrivances, water-activated, with burster, expelling charge or propelling charge UN0249
Ammunition, tear-producing with burster, expelling charge or propelling charge UN0019 Rocket motors with hypergolic liquids with or without an expelling charge UN0250
Ammunition, tear-producing with burster, expelling charge or propelling charge UN0301 Rocket motors with hypergolic liquids with or without an expelling charge UN0322
Ammunition, toxic with burster, expelling charge, or propelling charge UN0020 Substances, explosive, n.o.s UN0357
Ammunition, toxic with burster, expelling charge, or propelling charge UN0021 Substances, explosive, n.o.s UN0358

The following proper shipping names and corresponding identification numbers will have stowage code 20E removed from column (10B) of the HMT.

Proper shipping name UN No. Proper shipping name UN No.
Ammunition, smoke with or without burster, expelling charge or propelling charge UN0015 Ammunition, tear-producing with burster, expelling charge or propelling charge UN0018
Ammunition, smoke with or without burster, expelling charge or propelling charge UN0016 Ammunition, tear-producing with burster, expelling charge or propelling charge UN0019

During review of the explosive stowage codes it was noted that stowage code 1E was assigned to UN0504 1H-Tetrazole and UN0502 Rockets, with inert head. Stowage code 1E was removed in a final rule published on June 21, 2001, under Docket Number RSPA-2000-7702 (HM-215D) [66 FR 33316] entitled, “Harmonization with the United Nations Recommendations, International Maritime Dangerous Goods Code, and International Civil Aviation Organization's Technical Instructions” and, in this NPRM, PHMSA proposes to amend the listings for these two entries by removing these two codes whose requirements have been captured by other vessel stowage provisions.

Section 172.102Special Provisions

Section 172.102 lists special provisions applicable to the transportation of specific hazardous materials. Special provisions contain packaging requirements, prohibitions, and exceptions applicable to particular quantities or forms of hazardous materials. PHMSA is proposing the following revisions to the § 172.102, Special provisions:

Special Provision 47

Special provision 47 provides classification exceptions for mixtures of solids and flammable liquids. In this NPRM, PHMSA proposes to revise special provision 47 to clarify that the requirement that each packaging must correspond with a design type that has passed a leakproofness test at the Packing Group II level applies only to single packagings.

Special Provision 48

Special provision 48 provides classification exceptions for mixtures of solids and toxic liquids. In this NPRM, PHMSA proposes to revise special provision 47 to clarify that the requirement that each packaging must correspond with a design type that has passed a leakproofness test at the Packing Group II level applies only to single packagings.

Special Provision 49

Special provision 49 provides classification exceptions for mixtures of solids and corrosive liquids. In this NPRM, PHMSA proposes to revise special provision 49 to clarify that the requirement that each packaging must correspond with a design type that has passed a leakproofness test at the Packing Group II level applies only to single packagings.

Special Provision 101

In a NPRM published in the Federal Register on August 31, 2006 (71 FR 51895), we proposed to remove § 172.102(c)(1), Special provision 101. In the NPRM, we stated that with the introduction of the letter “G” in Column (1), which requires the n.o.s. and generic proper shipping names to be supplemented with the technical name of the hazardous material, Special Provision 101 became obsolete. Consequently, because we did not receive public comment, the amendment was adopted as proposed in a final rule published in the Federal Register on December 29, 2006 (71 FR 78596).

Consequences of the removal of § 172.102(c)(1) Special provision 101 in 2006 may have resulted in noncompliance for certain Department of Defense (DOD) explosive shipments. DOD recently asserted the current provisions in §§ 171.8 and 172.203(k) of the HMR do not permit technical names to be indicated in such a manner as former Special provision 101 required. For example, a DOD explosive shipment approved under the generic description “Articles, explosive, n.o.s.” was previously assigned Special provision 101 in column 7 of the § 172.101 Hazardous Materials Table that required the name of the particular substance or article to be specified as the technical name for the substance or article (e.g., “Fuze, Grenade, M219A2”) in association with the basic description. Therefore, in this notice, PHMSA is proposing to reinstate special provision 101 for the following HMT entries:

UN0349 Articles, explosive, n.o.s.

UN0350 Articles, explosive, n.o.s.

UN0351 Articles, explosive, n.o.s.

UN0352 Articles, explosive, n.o.s.

UN0353 Articles, explosive, n.o.s.

UN0354 Articles, explosive, n.o.s.

UN0355 Articles, explosive, n.o.s.

UN0356 Articles, explosive, n.o.s.

UN0462 Articles, explosive, n.o.s.

UN0463 Articles, explosive, n.o.s.

UN0464 Articles, explosive, n.o.s.

UN0465 Articles, explosive, n.o.s.

UN0466 Articles, explosive, n.o.s.

UN0467 Articles, explosive, n.o.s.

UN0468 Articles, explosive, n.o.s.

UN0469 Articles, explosive, n.o.s.

UN0470 Articles, explosive, n.o.s.

UN0471 Articles, explosive, n.o.s.

UN0472 Articles, explosive, n.o.s.

UN0382 Components, explosive train, n.o.s.

UN0383 Components, explosive train, n.o.s.

UN0384 Components, explosive train, n.o.s.

UN0461 Components, explosive train, n.o.s.

UN0357 Substances, explosive, n.o.s.

UN0358 Substances, explosive, n.o.s.

UN0359 Substances, explosive, n.o.s.

UN0473 Substances, explosive, n.o.s.

UN0474 Substances, explosive, n.o.s.

UN0475 Substances, explosive, n.o.s.

UN0476 Substances, explosive, n.o.s.

UN0477 Substances, explosive, n.o.s.

UN0478 Substances, explosive, n.o.s.

UN0479 Substances, explosive, n.o.s.

UN0480 Substances, explosive, n.o.s.

UN0481 Substances, explosive, n.o.s.

UN0485 Substances, explosive, n.o.s.

UN0482 Substances, explosive, very insensitive, n.o.s. or Substances, EVI, n.o.s.

Special Provision 118

Special provision 118 states that materials listing this special provision may not be transported under the provisions of Division 4.1 unless specifically authorized by the Associate Administrator. In the UN Model Regulations the corresponding special provision, SP 272, contained a note that the special provision referred to UN0143. This special provision in the UN Model Regulations has been revised to indicate that the special provision applies to both UN0143 and UN0150, as appropriate. To maintain consistency with the UN Model Regulations, in this NPRM PHMSA proposes to adopt this editorial note and revise special provision 118 by adding the language “(see UN0143 or UN0150 as appropriate)” following the existing text.

Special Provision 134

Special provision 134 would be revised to note that this provision also applies to equipment powered by wet batteries or sodium batteries that are transported with these batteries installed. This is a minor clarification of the original intent of this special provision.

Special Provision 155

Special provision 155 states that Fish meal or fish scrap may not be transported if the temperature at the time of loading either exceeds 35 °C (95 °F), or exceeds 5 °C (9 °F) above the ambient temperature, whichever is higher.

In this NPRM PHMSA proposes to revise special provision 155 by adding a reference to the new proper shipping name “krill meal.” Krill meal processes similar self-heating hazard characteristics to fish meal and scrap; therefore, application of this special provision is appropriate. This addition will clarify that special provision 155 applies to fish meal and fish scrap as well as krill meal. This revision is a clarification of the existing requirement.

Special Provision 237

Special provision 237 specifies that “Batteries, dry, containing potassium hydroxide solid, electric storage” must be prepared and packaged in accordance with the requirements of § 173.159(a), (b), and (c) and that for transportation by aircraft, the provisions of § 173.159(b)(2) are applicable.

In this NPRM PHMSA is proposing to add an additional sentence to special provision 237 clarifying the applicability of the provision. Specifically language is added to state that the entry for “Batteries, dry, containing potassium hydroxide solid, electric storage” may only be used for the transport of non-activated batteries that contain dry potassium hydroxide and that are intended to be activated prior to use by the addition of an appropriate amount of water to the individual cells.

Special Provision 238

Special provision 238 is added to address neutron radiation detectors. Neutron detection is a key component used in nuclear arms interdiction in addition to other applications such as nuclear reactor monitoring, neutron-based cancer treatments, neutron spallation, nondestructive testing and health physics applications. Most neutron radiation detectors contain boron trifluoride gas, UN1008, which is currently forbidden by passenger and cargo aircraft as noted in Columns (9A) and (9B) of the HMT. Currently, neutron radiation detectors that contain this gas can only be transported by air under the terms of a special permit.

ICAO recently adopted a special provision specifically addressing neutron radiation detectors. The recently adopted special provision A191 permits, under certain conditions the transportation by cargo aircraft of neutron radiation detectors that contain boron trifluoride. These conditions include quantity of gas limitations, construction and packaging specifications. The special provision also provides that under certain conditions these neutron radiation detectors containing not more than 1 gram of boron trifluoride gas are not otherwise subject to the ICAO Technical Instructions.

PHMSA granted a special permit, for the transportation by all modes, of certain neutron radiation detectors containing boron trifluoride gas. The limitations set forth in Special Provision A191 of the ICAO Technical Instructions do not exceed any limitations of the special permit and, therefore, PHMSA proposes to adopt and apply them to all modes of transportation except passenger-carrying aircraft by incorporating them into § 172.102(c)(1), Special provision 238. Specifically, the special provision will provide packaging requirements (including pressure limitations), quantities permitted, and package construction requirements for radiation detectors containing non-pressurized boron trifluoride gas in excess of 1 gram. The special provision also provides additional exceptions from the HMR based on the transport mode and other conditions. The special provision is applicable to the entry “UN1008, Boron trifluoride” in the HMT. PHMSA believes the adoption of this special provision provides an adequate level of safety for the transportation of these items, while providing flexibility and without the need to obtain a special permit.

Special Provision 328

A new special provision 328 is added to clarify that when lithium cells or batteries are contained in the fuel cell system, the item must be described under this entry and the entry “Lithium batteries, contained in equipment.” This special provision will be applied to UN3473 “Fuel cell cartridges or Fuel cell cartridges contained in equipment or Fuel cell cartridges packed with equipment, containing flammable liquids”; UN3476 “Fuel cell cartridges or Fuel cell cartridges contained in equipment or Fuel cell cartridges packed with equipment, containing water-reactive substances”; UN3477 “Fuel cell cartridges or Fuel cell cartridges contained in equipment or Fuel cell cartridges packed with equipment, containing corrosive substances”; UN3478 “Fuel cell cartridges or Fuel cell cartridges contained in equipment or Fuel cell cartridges packed with equipment, containing liquefied flammable gas”; and UN3479 “Fuel cell cartridges or Fuel cell cartridges contained in equipment or Fuel cell cartridges packed with equipment, containing hydrogen in metal hydride.”

Special Provision 360

A new Special Provision 360 would be added and assigned to UN3091, “Lithium batteries, contained in equipment” to clarify that vehicles powered only by lithium batteries must be assigned to identification number UN3071, “Battery powered vehicle”.

Special Provision 361

A new special provision 361 is added to clarify that certain capacitors with limited energy storage capability are excepted from the HMR. Specifically, the special provision will state that capacitors with an energy storage capacity of 0.3 Wh or less are not subject to the HMR. Furthermore this special provision will define energy storage capacity as the energy held by a capacitor, as calculated using the nominal voltage and capacitance.

Proposed § 173.176 provides that capacitors not installed in equipment must be transported in an uncharged state and capacitors installed in equipment must be transported in either an uncharged state or protected against short circuit. Certain types of capacitors such as asymmetrical capacitors are designed to maintain a terminal voltage. This special provision will also clarify the entry UN3499 does not apply to these capacitors. This special provision will be applied to the proposed HMT entry UN3499, “Capacitor, electric double layer (with an energy storage capacity greater than 0.3 Wh).”

Special Provision 362

A new special provision 362 is added to specify when a material can be considered a chemical under pressure. Specifically, the special provision will state that classification of these materials is to be based on hazard characteristics of the components in the propellant, the liquid, or the solid forms. Further, this special provision will detail the appropriate primary and subsidiary hazard classes to be assigned to chemicals under pressure. Special provision 362 would be added and assigned to the following HMT entries: UN3500, Chemical under pressure, n.o.s.; UN3501, Chemical under pressure, flammable, n.o.s.; UN3503, Chemical under pressure, corrosive, n.o.s.; UN3502, Chemical under pressure, toxic n.o.s.; UN3504, Chemical under pressure, flammable, toxic, n.o.s.; and UN3505, Chemical under pressure, flammable, corrosive, n.o.s.

Special Provision 363

Prior to the publication of the 17th Revised Edition of the UN Model Regulations, the transport of large amounts of fuel in machinery was not specifically addressed in international transport regulations. In the most recent biennium of the UNSCOE, some experts expressed concerns about the transport of large amounts of fuel in machinery. This concern lead the international community to adopt in The 17th Revised Edition of the UN Model Regulations a special provision associated with fuel-related Class 3 entries.

Special Provision 363, as adopted in the UN Model Regulations, requires an article that contains fuel in excess of the limited quantity authorized amount and is ineligible to be described as Dangerous Goods in Machinery or Apparatus, UN3363, to conform to several general provisions to avoid being subject to the remainder of the HMR. Shipments utilizing this special provision require that the means of containment be in compliance with the construction requirements of the competent authority, all valves or openings in the means of containment containing dangerous goods shall be closed during transport, the machinery or equipment shall be loaded in an orientation to prevent leakage, and: (1) If the means of containment has a capacity of not more than 450 liters, one label would be required; (2) if the means of containment has a capacity greater than 450 liters but not more than 1,500 liters, it must be labeled on all four sides; or (3) if the means of containment has a capacity greater than 1,500 liters, it must be placarded on each side and each end. Additionally, shipping papers are required for such articles.

In this NPRM, PHMSA proposes to adopt Special Provision 363 modeled on the corresponding special provision adopted in the UN Model Regulations. This special provision would be assigned to the following HMT entries for transportation by vessel: UN1202, Gas oil or Diesel fuel or Heating oil, light; UN1203, Gasoline including when mixed with ethyl alcohol, with not more than 10% alcohol; UN1223, Kerosene; UN1268, Petroleum distillates, n.o.s. or Petroleum products, n.o.s.; UN1863, Fuel, aviation, turbine engine; and UN3475, Ethanol and gasoline mixture or Ethanol and motor spirit mixture or Ethanol and petrol mixture, with more than 10% ethanol.

While PHMSA generally agrees with the concept of addressing machinery or apparatus containing flammable liquid fuels in amounts that exceed the authorized limited quantity amounts and are ineligible to be described as UN3363, Dangerous goods in machinery or apparatus, we do have concerns related to the potential impact that adopting this special provision would have on shippers of generators and other similar articles that may currently be described as UN3166, Engines internal combustion, and are not subject to fuel limitations when transported by highway or rail. Conversely, PHMSA is soliciting public comment regarding any potential negative impact on the efficient and seamless flow of international commerce if we choose not to adopt Special Provision 363 in a final rule.

Special Provision 365

With the official adoption of a new proper shipping name UN3506 Mercury contained in manufactured articles in the 17th Revised Edition of the UN Model Regulations to address manufactured articles containing mercury, PHMSA proposes to add a new special provision 365 stating that manufactured instruments and articles containing mercury should reference UN3506. This special provision will be applied to UN2809 Mercury.

Special Provision A60

Special Provision A60 permits UN2014, Hydrogen peroxide, aqueous solution, to be transported in excepted quantities provided a comparative fire test between packages containing the solution and identical packages containing water demonstrated no difference in the burning rate. The likelihood of finding discernible differences with more accurate test equipment used today is much greater than it would have been with equipment used when the test requirements were first developed. This more sensitive equipment often detects negligible differences between the two test subjects and, therefore, precludes transport of these small devices under the special provision. To address the issue, the ICAO Dangerous Goods Panel (DGP) adopted a proposal to allow small differences in burning rates.

In this NPRM we are proposing to harmonize with the ICAO Technical Instructions with regard to the comparative fire test for Hydrogen peroxide, aqueous solution. Special provision A60 is revised accordingly.

Special Provision A100

Special Provision A100 states that primary (non-rechargeable) lithium batteries and cells are forbidden for transport aboard passenger-carrying aircraft and secondary (rechargeable) lithium batteries and cells are authorized aboard passenger-carrying aircraft in packages that do not exceed a gross weight of 5 kg.

In this NPRM special provision A100 is revised to clarify the weight limitations for secondary lithium batteries are net and not gross quantities. There are some combinations of authorized battery packagings that contribute significantly towards the gross weight of the finished package. The intent of this proposed change is to indicate that the quantity limits for secondary lithium battery shipments aboard passenger-carrying aircraft are to be based on the actual weight of the batteries in each individual package and not the weight of the completed package.

Special Provision A103

Special Provision A103 specifies that lithium batteries contained in equipment is authorized aboard passenger carrying aircraft if the gross weight of the inner package of secondary lithium batteries or cells packed with the equipment does not exceed 5 kg (11 pounds).

In this NPRM special provision A103 is revised to clarify the weight limitations are net and not gross quantities. There are some combinations of authorized battery packagings that contribute significantly towards the gross weight of the finished package. The intent of this proposed change is to indicate that the quantity limits for secondary lithium battery shipments aboard passenger carry aircraft are to be based on the actual weight of the batteries in each individual package and not the weight of the completed package.

Special Provision A189

In this NPRM, we are proposing to add a new special provision, A189, which will be assigned to the HMT entry “UN2209, Formaldehyde solutions, with not less than 25 percent formaldehyde” indicating how Formaldehyde solutions with more than 25% are to be classified. It was suggested at the ICAO DGP that the entry for “UN2209, Formaldehyde solution with not less than 25% formaldehyde” implied that concentrations of less than 25% formaldehyde were not regulated. To clarify these requirements, the ICAO DGP adopted a new special provision detailing how differing percentage of formaldehyde solutions are regulated.

In this NPRM, we are proposing to add language detailing how differing percentage of Formaldehyde solutions are to be regulated in the new special provision A189. This special provision will be applied to UN3334, Aviation regulated liquid, n.o.s. and NA3082, Other regulated substances, liquid, n.o.s.

Special Provision A192

A new special provision, A192, is added noting that regardless of the Division 6.1 subsidiary hazard indicated in the HMT, the poison subsidiary risk label and an indication of this subsidiary risk on the shipping paper are not required for manufactured articles containing less than 0.45 kg (1 pound) of mercury. This provision aligns with the decision of the UN Sub-Committee to ensure that transport of such articles, particularly by air, is not impeded due to mercury's revised classification.

Special Provision A200

As previously discussed, a new special provision, A200, is added stating the entries assigned this special provision must be transported as cargo when transported by aircraft and cannot be carried onboard an aircraft by passengers or crewmembers either in or as carry-on baggage, checked baggage, or on their person unless specifically excepted by§ 175.10, “Exceptions for Passengers, Crewmembers, and Air Operators.” This special provision would be assigned to articles and will be applied to: UN3166, Engines, internal combustion or Engines, fuel cell, flammable gas powered; UN3166, Engines, internal combustion, or Engines, fuel cell, flammable liquid powered; UN3166, Vehicle, flammable gas powered or Vehicle, fuel cell, flammable gas powered; UN3166, Vehicle, flammable liquid powered or Vehicle, fuel cell, flammable liquid powered; UN0503, Air bag inflators, or Air bag modules, or Seat-belt pretensioners; and, UN3268, Air bag inflators, or Air bag modules, or Seat-belt pretensioners.

Special Provision B120

A new special provision B120 is added to specify the use of FBCs conforming to the requirements in Subpart R and Subpart S of part 178 of this subchapter are permitted. The special provision is applicable to the following entries:

Proper shipping name UN No.
Ammonium nitrate based fertilizer UN2067
Ammonium nitrate, with not more than 0.2% total combustible material, including any organic substance, calculated as carbon to the exclusion of any other added substance UN1942
Calcium nitrate UN1454
Environmentally hazardous substance, solid, n.o.s UN3077
Magnesium nitrate UN1474
Naphthalene, crude or Naphthalene, refined UN1334
Paraformaldehyde UN2213
Potassium nitrate UN1486
Sodium carbonate peroxyhydrate UN3378
Sodium nitrate UN1498
Sodium nitrate and potassium nitrate mixtures UN1499
Sodium perborate monohydrate UN3377
Sulfur (domestic and international entries) UN1350

FBCs must conform to the performance-oriented construction standards and testing criteria in new subparts R and S of part 178. In addition, shipments of FBCs must be prepared and otherwise conform to the general requirements for bulk packages in subpart B of part 173 and the proposed new § 173.37.

IBC Codes

In a final rule published in the Federal Register on January 19, 2011 (76 FR 3308; HM-215K), the Table 1 (IBC Codes) in paragraph (c)(4) were editorially revised to remove UN Specifications 31A, 31B and 31N from IBC Codes IB4 through IB8. The revision was consistent with amendments to international standards that removed the specifications from the indicated codes in the table because IBC Codes IB4 through IB8 are assigned to solids, whereas, UN Specifications 31A, 31B, and 31N are authorized for transportation of liquids in IBC Codes IB1 through IB3 and are assigned to liquid materials only. In the January 19, 2011 final rule, PHMSA inadvertently failed to also remove the remaining liquid IBC specifications (31H1, 31H2, 31HZ1, and 31HZ2) from IB Codes IB4 through IB8. Therefore, in this NPRM, PHMSA is editorially correcting the IBC Code Table in § 172.102(c)(4).

Special Provision TP39

A new special provision, TP39, is added and assigned to HMT entry“UN2381, Dimethyl disulfide.” This special provision indicates that portable tank instruction T4 may continue to be applied until December 31, 2018. This will provide more time for portable tank transporters to transition their current fleets.

Special Provision TP40

A new special provision TP40 is added and assigned to HMT entries “UN3500, Chemical under pressure, n.o.s.; UN3501, Chemical under pressure, flammable, n.o.s.; UN3503, Chemical under pressure, corrosive, n.o.s., UN3503; UN3502, Chemical under pressure, toxic n.o.s.; UN3504, Chemical under pressure, flammable, toxic, n.o.s.; and UN3505, Chemical under pressure, flammable, corrosive, n.o.s.” The special provision indicates that the portable tanks must not be transported when connected with spray application equipment. This will provide an additional measure preventing inadvertent release of hazardous materials in transport.

Special Provision TP41

A new Special provision TP41 is added and assigned to HMT entries “UN3148, Water-reactive liquid, n.o.s.,” indicating that the portable tank instruction T9 may continue to be applied until December 31, 2018.

Special Provision TP50

Special provision T50 is revised to note that this provision is applicable to chemicals under pressure as well as liquefied compressed gases. Special provision T50 would be assigned to HMT entries “UN3500, Chemical under pressure, n.o.s.; UN3501, Chemical under pressure, flammable, n.o.s.; UN3503, Chemical under pressure, corrosive, n.o.s., UN3503; UN3502, Chemical under pressure, toxic n.o.s.; UN3504, Chemical under pressure, flammable, toxic, n.o.s.; and UN3505, Chemical under pressure, flammable, corrosive, n.o.s.”

Special Provision W10

A new special provision W10 is added and assigned to HMT entries “UN3486 Calcium hypochlorite mixture, dry, corrosive with more than 10% but not more than 39% available chlorine” and to “UN2208 Calcium hypochlorite mixtures, dry, with more than 10 percent but not more than 39 percent available chlorine” indicating that when offered for transportation by vessel, the use of Large Packagings is prohibited. This provision is being adopted to align with a recent IMO change forbidding these commodities from being transported by vessel in large packages.

Section 172.202

Section 172.202 establishes requirements for shipping descriptions on shipping papers. As part of these shipping paper requirements, in many situations a net or gross quantity of the hazardous materials transported must be included. At the 23rd meeting of the ICAO DGP, the issue of notation of quantities on shipping documents was raised. Specifically, it was noted that some confusion as to whether or not the net quantity or a gross mass is required on the shipping documents on particular shipments, such as limited quantities. At this meeting an amendment to the ICAO Technical Instructions was proposed and adopted designed to clarify what quantities (i.e. net or gross quantity) were required on the transport document for packages containing limited quantities where different hazardous materials are packed together in the same outer packaging.

In this NPRM, PHMSA proposes to adopt a similar provision to the one addressed by the ICAO DGP discussed above. Specifically, PHMSA proposes to add a new paragraph (a)(6)(vii) stating that for shipments containing hazardous materials in limited quantities with a “30 Kg gross” limit in Column (9A) or (9B) of the § 172.101 Hazardous Materials Table and different hazardous materials packed together in the same outer packaging, the net quantity of each hazardous material followed by the gross mass of the completed package should be shown on the shipping paper.

This clarification will address a transport scenario currently not addressed in the HMR thus alleviating confusion regarding the shipping paper requirements of such shipments. Furthermore, this will harmonize the HMR with the ICAO Technical Instructions and avoid shipping paper discrepancies for international shipments.

Section 172.301

This section details the general marking requirements for non-bulk packagings. Specifically, this section states what information (proper shipping name and identification number, technical names, consignee's or consignor's name, etc.) must be displayed on the outside of non-bulk packages. While the HMR requires that an identification number, preceded by “UN” or “NA” as appropriate, be marked on the outside of a non-bulk packaging a specific size of this marking is not specified.

In this NPRM PHMSA proposes to add specific size requirements for the “UN” or “NA” markings. As proposed these markings must be marked in characters at least 12 mm (0.47 inches) high, however, packages with a maximum capacity of 30 liters (7.92 gallons) or 30 kg (66 pounds) or less must be marked with characters at least 6 mm (0.2 inches) high and packages having a maximum capacity 5 liters (1.32 gallons) or 5 kg (11 pounds) or less must be marked in a size appropriate for the size of the package.

PHMSA proposes this minimum size marking for the “UN” or “NA” markings to align with newly adopted requirements in the 17th Revised Edition of the UN Model Regulations. PHMSA recognizes the importance of establishing a minimum size requirement for the internationally recognized “UN” identification number marking system. The HMR currently specifies size requirements for the package markings specified in § 178.3(a)(4). Specifically, for package markings, letters and numerals must be at least 12.0 mm (0.47 inches) in height except that for packagings of less than or equal to 30 L (7.9 gallons) capacity for liquids or 30 kg (66 pounds) capacity for solids the height must be at least 6.0 mm (0.2 inches). Without a minimum size requirement for hazard communication, shippers may mark packages in a format that makes it very hard for first responders to identify the commodity associated with a particular package. Therefore in this NPRM, PHMSA proposes to specify a marking size consistent with package marking sizes specified in § 178.3(a)(4) and those adopted in the 17th Revised Edition of the UN Model Regulations.

Section 172.312

Section 172.312 details the specific marking requirements for liquid hazardous materials in non-bulk packagings. Paragraph (a) of this section describes scenarios when package orientation arrows must be displayed on the outside of a package. Provided certain criteria are met, paragraph (c) excepts certain shipments from the requirements of paragraph (a) and thus, the requirement to display the package orientation arrows on the package. Currently § 173.312(c)(3) states that when offered or intended for transportation by aircraft, packages containing flammable liquids in inner packagings of 120 mL (4 fluid oz.) or less prepared in accordance with § 173.150(b) or (c) of this subchapter when packed with sufficient absorption material between the inner and outer packagings to completely absorb the liquid contents are not required to display the package orientation arrows on the outside of the package. The ICAO TI have been amended to extend this exception to the package orientation markings to all liquid hazardous materials in inner packagings of 120 mL (4 fluid oz.) when packed with sufficient absorption material between the inner and outer packagings to completely absorb the liquid contents. In this NPRM, PHMSA is proposing to adopt this change, consistent with the amendment made to the ICAO TI to extend the exception for the display of the package orientation arrows to all liquid hazardous materials in inner packagings of 120 mL (4 fluid oz.) when packed with sufficient absorption material between the inner and outer packagings to completely absorb the liquid contents.

Section 172.604

Section 172.604 prescribes emergency response telephone number requirements. Paragraph (d) of this section provides a listing of materials that are excepted from the requirement to provide an emergency response telephone number on a shipping document.

In this NPRM, PHMSA proposes to add “Krill Meal, PGIII” to the list of materials excepted from the emergency response telephone number requirements. Krill meal poses similar hazards to fish scrap and meal; therefore, in this NPRM we are providing Krill meal with the same exception from the emergency response telephone number requirements as fish scrap and meal.

Part 173 Back to Top

Part 173 of the HMR describes the general requirements for shipments and packagings of hazardous materials. Consistent with amendments adopted by the UN Model Regulations, PHMSA proposes to adopt changes throughout the Part 173 packaging requirements to authorize more flexibility when choosing packages for hazardous materials. Specifically PHMSA proposes to authorize the use of the following packaging types and materials:

The specific packaging requirements for Class 1 explosive materials are specified in § 173.62. In this NPRM PHMSA is proposing to revise § 173.62 to authorize wood as an appropriate material used to construct receptacles, inner and outer intermediate packagings, and intermediate packagings/dividing partitions for certain explosives. Furthermore, in this NPRM PHMSA is proposing to authorize the use of metals other than steel or aluminum in specification packagings, specifically drums (1N1 or 1N2) and boxes (4N), as appropriate. This authorization would not include chlorosilanes under § 173.206 because of corrosion concerns. Otherwise, it authorizes the use of closed head drums where open head drums are generally permitted. PHMSA believes these amendments would provide greater flexibility in packaging while maintaining an equivalent level of safety.

Consistent with amendments adopted by the ICAO Technical Instructions, PHMSA proposes to adopt changes in various sections on Part 173 where certain articles, items, and materials are excepted from the requirements of the subchapter. There is a potential for these excepted articles, items, and materials to be inappropriately carried aboard an aircraft by passengers or crewmembers. The proposed changes will address this concern by clarifying that certain excepted articles, items and materials, identified by ICAO as posing a safety risk, must be transported as cargo and cannot be carried onboard an aircraft by passengers or crewmembers as carry-on baggage, checked baggage, or on their person unless specifically excepted by § 175.10, “Exceptions for Passengers, Crewmembers, and Air Operators.” The amended sections include §§ 173.21, 173.159a, 173.162, 173.164, 173.175, 173.219, and 173.306. For UN3166 and UN3268, Special Provision A200 will be created to communicate this requirement and a reference to special provision A200 would be placed in column 7 of the HMT for these entries.

Section 173.12

This section specifies the exceptions for shipment of waste materials including the requirements for waste packages known as “lab packs.” A lab pack, although not specifically defined in § 171.8, is considered a large outer packaging containing small inner packagings that are filled with various compatible laboratory hazardous wastes. Paragraph (b) of this section specifies the authorized inner and outer packagings for lab packs.

In this NPRM, PHMSA proposes to revise paragraph (b)(2)(ii)(a) of this section by adding 1N2 metal drums to the permitted outer packagings currently authorized for a lab pack.

Section 173.21

Section 173.21 prescribes materials and packages forbidden for transport. In this NPRM, PHMSA is proposing to correct the IMDG Code section reference to control temperature requirements in § 173.21(f)(3)(ii) from 7.7 to 7.3.7.

Section 173.37

Currently, the HMR does not include a section that prescribes general requirements for packaging hazardous materials in Flexible Bulk Containers (FBCs). In this NPRM, PHMSA is proposing such requirements in new § 173.37 in a similar format to the general requirements for other bulk and large packagings (e.g., portable tanks, IBCs, etc.) in subpart B of part 173. This section will include, but not be limited to, requirements addressing the initial use and reuse of FBCs, capacity requirements and general transport conditions. Consistent with the use and reuse requirements of other large and bulk packagings, the general requirements in part 173 complement the construction and manufacture specifications for such bulk packagings in part 178 of the HMR.

In this NPRM, PHMSA is proposing that FBCs may be reused, and must be given a visual examination prior to reuse. Furthermore, the general requirements for FBCs would specify that FBCs must be transported in a conveyance with rigid sides and ends that extend at least two-thirds the height of the FBC, must not be offered for transportation in freight containers, and may not exceed 15 cubic meters in capacity.

Section 173.50

Section 173.50 provides definitions for the various divisions of Class 1 (explosives) referenced in Subpart C of Part 173. Paragraph (b) of this section notes that Class 1 (explosives) are divided into six divisions. Division 1.6 is described as an explosive consisting “of extremely insensitive articles that do not have a mass explosive hazard. This division is comprised of articles that contain only extremely insensitive detonating substances and that demonstrate a negligible probability of accidental initiation or propagation.”

In this NPRM PHMSA is proposing to remove the word “detonating” from this definition to align with the revised definition provided in the 17th Revised Edition of the UN Model Regulations.

Section 173.59

Section 173.59 provides definitions of explosive terms related to the transport and classification of explosives used throughout subpart C of part 173. These definitions are intended for information only and are not to be used for purposes of classification or to replace proper shipping names prescribed in § 172.101. In the UN Model Regulations, Appendix B to Chapter 3 contains a similar list of explosive definitions which are also intended for information only and are not to be used for purposes of hazard classification.

In April 2010, the United States and the United Kingdom submitted a formal document regarding proposed modifications to the UN test series 7 for consideration by the UN Subcommittee of Experts on the Transport of Dangerous Goods. Test series 7 is used to classify explosives into the appropriate class. [2] This paper sought to modify the test series 7 to more accurately address the classification of Division 1.6. Specifically, Division 1.6 is for extremely insensitive detonating articles and the proposed changes in the US/UK paper are designed to ensure that the probability of accidental initiation or propagation of an article attaining this division remains negligible.

In the 17th Revised Edition of the UN Model Regulations, the proposals presented in the US/UK paper regarding the UN test series 7 were adopted. Among the adopted proposals was the addition of various explosive specific definitions referencing the modifications to the UN test series 7. In this NPRM, we are proposing to revise the various definitions prescribed in § 173.59. Specifically, we propose revising the definition for “Articles, explosive, extremely insensitive (Articles, EEI)” by removing the word “detonating” and adding the words “tools” after “starter pistols” in the definition for “Cartridges, blank.” We also propose to replace the definition for “Explosive, extremely insensitive detonating substances (EIDS)” with a new definition for “Explosive, extremely insensitive substances (EIS).” Lastly, we propose to add a definition for “Auxiliary explosive component, isolated.” The addition of and revisions to these definitions will provide consistency with international regulations and clarity when utilizing the UN test series 7 for explosive classification.

Section 173.62

Section 173.62 prescribes the specific packaging requirements for explosives. These packaging requirements stipulate the permitted inner, intermediate, and outer packagings as well as any specific additional packaging information. These packaging requirements are generally aligned with the requirements stipulated in the UN Model Regulations.

In this NPRM, PHMSA is proposing to revise various packaging provisions in the “Table of Packing Methods” in this section to align with changes adopted in the 17th Revised Edition of the UN Model Regulations. The revisions to the authorized packaging methods provide greater flexibility when packaging explosives while retaining an appropriate level of safety. These changes include, but are not limited to, permitting various explosives to be transported in closed head drums in addition to the already permitted removable head drums and adding the option to utilize wooden inner and intermediate packagings in various packaging provisions.

Section 173.63

Section 173.63 provides packaging exceptions for specific types of low hazard explosive materials including certain detonators, small arms ammunition and detonating cord. Paragraph (b) of this section prescribes the limited quantity requirements for small arms ammunition and blank cartridges for tools. Specifically, § 173.63(b)(1)(i) authorizes Cartridges, small arms (UN0012), and Cartridges for tools, blank used to project fastening devices (UN0014), classed as Division 1.4S explosive articles, to be offered for transportation and transported as limited quantity material when packaged in accordance with § 173.63(b)(2) and marked as prescribed in § 172.315(a) or (b) for transportation by all modes.

Section 173.115

Section 173.115 prescribes the definitions for Class 2 materials. Paragraph (k) of this section specifies how the oxidizing ability of certain Division 2.2 gases is determined. Currently, the HMR references ISO standards that include test and calculations used to determine the oxidizing ability of certain Division 2.2 gases. The UN Model Regulations and the ICAO Technical Instructions replace references to ISO standards 10156:1996 and 10156-2:2005 with the updated version ISO 10156:2010.

Based on its technical review, PHMSA believes the updated standard provides an adequate level of safety and proposes to reference the standard in this section and add it to the list of IBR materials in § 171.7.

Section 173.121

Section 173.121 prescribes the requirements for selection of packing groups for Class 3 flammable liquids. Paragraph (b) of this section describes the criteria for inclusion of viscous Class 3 materials in Packing Group III.

ICAO adopted requirements in the Technical Instructions that increased the quantity of viscous Class 3 flammable liquids permitted reclassification from Packing Group II to Packing Group III from 30 L (7.9 gal) per package to 100 L (26.42 gal) per package when offered for transport by cargo aircraft.

In this NPRM, PHMSA proposes to expand the per package amounts of viscous Class 3 material meeting the requirements in § 173.121(b). The increase will facilitate multi-modal transportation by permitting shipments offered by highway, rail, and cargo-carrying aircraft to utilize the same100 L criteria.

Section 173.134

Provisions contained in the UN Model Regulations, Chapter 2.6, Class 6—Toxic and Infectious Substances, relating to the transportation of medical devices and equipment, have been amended to except medical equipment which has been drained of free liquid from the requirements of the UN Model Regulations. In addition, except for medical devices or equipment being transported for disposal, or medical devices or equipment contaminated with or suspected of contamination with a Category A infectious substance, the UN Model Regulations have been amended to exempt medical devices or equipment potentially contaminated with or containing infectious substances which are being transported for disinfection, cleaning, sterilization, repair or equipment evaluation from all other requirements of the UN Model Regulations, provided they meet certain packaging requirements.

In this NPRM, PHMSA proposes to amend § 173.134, “Class 6, Division 6.2—Definitions and Exceptions” by adopting the additional exemptions for medical devices and equipment.

Section 173.158

Section 173.158 prescribes packaging requirements for nitric acid mixtures of varying concentrations. In this NPRM, PHMSA is proposing to revise the list of outer packagings permitted for nitric acid mixtures of varying concentrations.

Specifically, PHMSA proposes to revise paragraph (d)(2) by adding 1N2, 4A, 4B and 4N packagings to the list of authorized outer packagings of combination packages for nitric acid of 90 percent or greater concentration, when offered for transportation or transported by rail, highway, or water, in addition to the packaging options currently authorized.

PHMSA also proposes to revise paragraph (e) of this section pertaining to nitric acid of less than 90 percent concentration, when offered for transportation or transported by rail, highway, or water. Specifically, this paragraph is revised to permit packagings of specification 4A, 4B, or 4N metal boxes for certain nitric acid concentrations.

Further, PHMSA proposes to revise paragraphs (f)(3), (g) and (h) by adding specification 1N2, 4A, 4B and 4N packagings to the list of authorized outer packagings of combination packagings for nitric acid of the following concentrations: (1) Nitric acid of 70 percent or less concentration, when offered for transportation or transported by rail, highway, or water; (2) Nitric acid of more than 70 percent concentration, when offered for transportation or transported by cargo aircraft only; and (3) Nitric acid of less than 70 percent concentration, when offered for transportation in cargo aircraft only.

The addition of these packaging options will increase flexibility for shippers when determining the appropriate packaging for nitric acid mixtures, in addition to the packaging options currently authorized.

Section 173.159a

Section 173.159a provides exceptions for non-spillable batteries. Paragraph (d) of this section excepts non-spillable batteries from the requirements of the HMR provided certain criteria, including specific packaging requirements and the absence of free-flowing liquid in the battery, are met.

In this NPRM, PHMSA is proposing to clarify paragraph (d) of this section by adding a new subparagraph (b)(3) stating that “for transport by aircraft, must be transported as cargo.” This clarification will align the HMR with the previously discussed changes made to the ICAO TI with regard to the air transport of non-spillable batteries that are excepted from the HMR.

Section 173.160

Section 173.160 prescribes packaging requirements for “Bombs, smoke, non-explosive” when shipped without ignition devices. In this NPRM, PHMSA is proposing to revise the list of packagings permitted for “Bombs, smoke, non-explosive” shipped without ignition devices. Specifically, PHMSA proposes to add the authorization to use metal (4A, 4B, and 4N), fiberboard (4G) or solid plastic (4H2) boxes, or metal (1A2, 1B2, and 1N2), plastic (1H2), plywood (1D), or fiber (1G) drums.

Section 173.162

Section 173.162 prescribes the packaging requirements for “UN2803, Gallium.” In this NPRM, PHMSA proposes to revise paragraph (a)(1), which authorized combination packagings intended to contain liquids consisting of glass, earthenware, or rigid plastic inner packagings with a maximum net mass of 15 kg (33 pounds) each. Specifically, PHMSA proposes to revise these requirements to permit both open and closed steel, metal, other that steel and aluminium drums (1A1, 1N1, 1N2, 1H1, 3A2 or 3H2) in addition to the packaging options currently authorized.

Further, PHMSA proposes to revise paragraph (a)(2), which authorizes packagings intended to contain liquids consisting of semi-rigid plastic inner packagings of not more than 2.5 kg (5.5 pounds) net capacity each, individually enclosed in a sealed, leak-tight bag of strong puncture-resistant material. Specifically, PHMSA proposes to revise these requirements to permit metal, other than steel or aluminium (4N) boxes; metal, other than steel or aluminium drums (1N1, 1N2); and plastic drums (1H1 or 1H2) in addition to the packaging options currently authorized.

In addition, PHMSA is proposing to clarify paragraph (d) by adding a new subparagraph (b)(3) stating that “for transport by aircraft, must be transported as cargo.” This clarification will align the HMR with the previously discussed changes adopted in the ICAO Technical Instructions regarding the air transport of gallium otherwise excepted from the HMR.

Section 173.164

Section 173.164 prescribes the packaging requirements for mercury (metallic and articles containing mercury). In this NPRM, PHMSA proposes to revise paragraph (a)(1), which authorized inner packagings of earthenware, glass or plastic containing not more than 3.5 kg (7.7 pounds) of mercury, or inner packagings that are glass ampoules containing not more than 0.5 kg (1.1 pounds) of mercury, or iron or steel quicksilver flasks containing not more than 35 kg (77 pounds) of mercury. Specifically, PHMSA proposes to revise these requirements to permit steel drums; metal, other that steel and aluminum drums (1A1, 1N1, 1N2) and metal, other than steel or aluminum boxes (4N), in addition to the packaging options currently authorized in paragraphs (a), (b) and (c).

Paragraph (f) is added to provide an exception to the requirements of the HMR for vessel transport of manufactured articles or instruments containing less than 0.45 kg (1.0 pound) of mercury. This exception is inserted to mirror an existing IMDG Code provision and harmonize the requirements for vessel shipments of mercury contained in manufactured articles as much as possible.

In addition, PHMSA is proposing to clarify paragraphs (a)(5), (b), and (c)(2) of this section by adding the phrase “when transported as cargo.” This clarification will align the HMR with the previously discussed changes adopted in the ICAO Technical Instructions regarding the air transport of manufactured articles containing mercury otherwise excepted from the HMR.

Section 173.165

Section 173.165 prescribes the transport and packaging requirements for polyester resin kits. In this NPRM, PHMSA is proposing to revise § 173.165 to better align the packaging and other requirements for UN3269, Polyester resin kits with the various international modal standards. These proposed amendments are also intended to correct inconsistencies adopted in a final rule published in the Federal Register on January 19, 2011 (76 FR 3308; HM-215K).

Section 173.175

Section 173.175 prescribes the transport and packaging requirements for permeation devices. Currently, permeation devices containing hazardous materials that are used for calibrating air quality monitoring devices are not subject to the HMR provided they meet specific requirements that include packaging, quantity limitations, testing, and transport controls.

In this NPRM, PHMSA is proposing to add a new paragraph (g) stating that “for transport by aircraft, must be transported as cargo.” This clarification will align the HMR with changes adopted in the ICAO Technical Instructions regarding the air transport of permeation devices that are otherwise excepted from the HMR.

Section 173.176

Electric double layer capacitors are devices that store but do not produce electrical energy. They contribute to increased fuel efficiency in many alternative energy solutions such as hybrid vehicles. Some double layer capacitors contain flammable liquid absorbed in a solid with small amounts present as free liquid while others use a liquid electrolyte. Currently, the HMR do not contain specific requirements to address the transport of electric double layer capacitors.

New Section 173.176 addresses electric double layer capacitors and is proposed in this NPRM. If adopted, the section would prescribe the testing, marking, safety, and packaging requirements for electric double layer capacitors with an energy storage capacity greater than 0.3 Wh. PHMSA proposes to incorporate these requirements consistent with the 17th Revised Edition of the UN Model Regulations. The proposed amendments in this NPRM address potential electrical and other hazards arising from the release of hazardous materials during the transportation of these articles.

Section 173.181

Section 173.181 prescribes the non-bulk packaging requirements applicable to pyrophoric liquids.

Currently, the transport conditions specified in paragraph (b)(1) of this section specify that Division 2.2 compressed gases, including oxygen are permitted; however, oxygen generators are not. In this NPRM, PHMSA proposes to broaden the materials permitted in life-saving appliances by modifying paragraph (b)(1) to include liquefied gases as well.

Paragraph (c) of this section prescribes the packaging requirements and exceptions provided for life saving appliances. Subsequent changes are proposed to paragraph (c)(1) of this section to reflect this inclusion of liquefied gases discussed previously. Furthermore, paragraph (c)(5) currently states that, for other than transportation by aircraft, life-saving appliances containing no hazardous materials other than carbon dioxide with a capacity not exceeding 100 cm [3] are not subject to the provisions of this subchapter provided they are overpacked in rigid outer packagings with a maximum gross mass of 40 kg. In this NPRM, PHMSA is proposing to revise the exception in (c)(5) by replacing the language “carbon dioxide” with “cylinders of Division 2.2 compressed or liquefied gases with no subsidiary risk,” and the quantity limit “100 cm [3] with “120 ml, installed solely for the purpose of activating the appliance.”

In addition, PHMSA proposes to further clarify paragraph (c)(5) of this section by adding the statement, “For transportation by aircraft, such appliances must be transported as cargo.” This clarification aligns the HMR with the recently adopted changes in the ICAO Technical Instructions regarding the air transport of life saving appliances that would otherwise be excepted from the HMR.

Section 173.221

Section 173.221 prescribes the non-bulk packaging requirements for Polymeric beads (or granules), expandable, evolving flammable vapor and Plastic molding compound in dough, sheet or extruded rope form, evolving flammable vapor. In this NPRM, PHMSA is proposing to add the following packaging authorizations; metal (4A, 4B, or 4N), and plastic (4H1 or 4H2) drums, and 1N1, 1N2 drums in vapor tight metal or plastic jerricans (3A1, 3A2, 3B1, 3B2, 3H1, or 3H2). PHMSA is also proposing to add a paragraph to the section that will reference the reader to a newly created § 176.907 for cargo transport and hazard communication marking requirements for shipments of Polymeric beads expandable, evolving flammable vapor and Plastic molding compound in dough, sheet or extruded rope form, evolving flammable vapor when transported by vessel. These changes are proposed to address the safety hazard presented by shipments of polymeric beads or plastic molding compounds off-gassing flammable vapors during vessel transport. See Section 176.907 for a detailed discussion of our proposed addition of these vessel cargo transport requirements.

Section 173.225

Section 173.225 prescribes the packaging requirements and other provisions for organic peroxides. Packaging requirements for organic peroxides are very specific and include requirements for the concentration by mass permitted, diluents percentage, water mass, temperature controls and organic peroxide specific packing methods.

Paragraph (c) of this section contains and describes the organic peroxide table and how specific organic peroxides are to be transported. In addition, paragraph (e) contains a separate table that prescribes the packaging requirements for organic peroxides packaged in IBCs. As self-insulating hazardous materials, organic peroxides can pose different risks when transported in larger quantities. Thus, a separate table unique to the transport of these substances in IBCs is contained in the HMR. The “Organic Peroxide IBC Table” includes maximum quantities permitted to be packaged and any temperature and emergency controls.

The organic peroxides tables in paragraphs (c) and (e) specify by technical name those organic peroxides that are authorized for transportation and not subject to the approval provisions of § 173.128. An organic peroxide identified by technical name is authorized for transportation only if it conforms to all applicable provisions of these tables. In this NPRM, we are proposing to amend the Organic Peroxides Tables in § 173.225 by adding new entries and revising current entries to account for new organic peroxides and formulations that are commercially available.

The following entries are added in the § 173.225(c) organic peroxides table:

UN3106, “([3R-(3R,5aS,6S,8aS,9R,10R,12S,12aR**)]-Decahydro-10methoxy-3,6,9-trimethyl-3,12-epoxy-12H-pyrano[4,3-j]-1,2-benzodioxepin)”

UN3110, “3,6,9-Triethyl-3,6,9-trimethyl-1,4,7-triperoxonane”

UN3119, “Di-(3,5,5-trimethylhexanoyl) peroxide”

The following current entries in the § 173.225(c) organic peroxides table are amended:

UN3115, “Diisopropyl peroxydicarbonate”

UN3115, “Di-(3,5,5-trimethylhexanoyl) peroxide”

The following entries are added to the § 173.225(e) Organic Peroxide IBC Table:

UN3119 “Diisobutyryl peroxide, not more than 28% as a stable dispersion in water”

UN3119, “Diisobutyryl peroxide, not more than 42% as a stable dispersion in water”

The following entries are amended in the § 173.225(e) Organic Peroxide IBC Table:

UN3119 “Di-(3,5,5-trimethylhexanoyl) peroxide, not more than 38% in diluent type A”

UN3119 “1,1,3,3-Tetramethylbutyl peroxyneodecanoate, not more than 52%, stable dispersion, in water”

Section 173.226

Section 173.226 prescribes the packaging requirements for Materials poisonous by inhalation, Division 6.1, Packing Group I, Hazard Zone A. Specifically, this section authorizes the transport of Materials poisonous by inhalation, Division 6.1, Packing Group I, Hazard Zone A in specification cylinders, specification drums packaged further in specification drums and combination packages. In this NPRM, PHMSA proposes to revise the requirements of paragraph (c) by adding an authorization to package such materials in “Metal box other than steel or aluminum: 4N” drums. In addition, PHMSA is correcting an editorial error by replacing the incorrect wording “Expanded plastic box: 4H2” with the correct wording “Expanded plastic box: 4H1.”

Section 173.230

Section 173.230 prescribes the transport requirements for fuel cell cartridges containing hazardous material. Paragraph (e) of this section prescribes the packaging requirements for fuel cell cartridges containing hazardous material. Furthermore, paragraph (e)(2)(ii) notes that “Fuel cell cartridges contained in equipment must be protected against short circuits and the entire fuel cell system must be protected from unintentional activation. The equipment must be securely cushioned in the outer packaging.” As currently stated in the HMR, this requirement may imply that only fuel cell cartridges contained in equipment, not the fuel cell system, would have to be protected against short circuits. This is not the intent of this requirement. Therefore, in this NPRM, PHMSA is proposing to clarify that the entire fuel cell system must be protected against short circuits and unintentional activation.

Section 173.240

Section 173.240 prescribes the bulk packagings authorized for certain low hazard solid materials. As discussed previously in this NPRM, PHMSA is proposing the adoption of flexible bulk container provisions throughout the HMR.

In this section, PHMSA proposes to add paragraph (f) that authorizes the use of FBCs for certain low hazard solid materials. Specifically, paragraph (f) will permit the use of FBCs if B120 is indicated in Column (7) of the specific entry in § 172.101 HMT and the FBC conforms to the requirements in subparts R and S of part 178 of the HMR. Furthermore, paragraph (f) notes that FBCs may not be used for Packing Group I or II hazardous materials. Only select low hazard solid materials are authorized for transport in FBCs. The use of FBCs for the transportation of an HMT entry not assigned special provision B120 is prohibited.

Section 173.306

Section 173.306 prescribes the exceptions for limited quantities of compressed gases including aerosols. Paragraph (a) of this section prescribes the general requirements for limited quantities of compressed gases while paragraph (j) specifically addresses aerosols and receptacles small, containing gas, with a capacity of less than 50 mL.

In this NPRM, PHMSA proposes to revise paragraph (j) to note that aerosols conforming to this paragraph, when offered for transportation by air, must be transported as cargo unless specifically authorized for transport in checked or carry-on baggage. This clarification will align the HMR with the previously discussed changes adopted in the ICAO Technical Instructions regarding the air transport of aerosols that are otherwise excepted from the HMR.

Section 173.313

Section 173.313 contains instructions for UN portable tanks and the table for liquefied compressed gases. The UN Portable Tank Table for Liquefied Compressed Gases is referenced in § 172.102(c)(7)(iii) of the HMR for portable tanks used to transport liquefied compressed gases.

Chemical manufacturers throughout the world are currently supplying pressurized products contained and transported in gas cylinders. The products are liquids or solids such as adhesives, coatings and cleaners combined with a gas or gas mixtures in pressure receptacles under sufficient pressure to expel the contents. These mixtures are typically expelled from the pressurized receptacles as foams, streams or thick sprays. Under the current HMR these types of products are classified as liquefied gases and transported in accordance with the applicable sections for the liquefied gases in which they are classified. A typical product however is a combination of a propellant (gas phase) and a liquid or solid component, and therefore the term liquefied gas does not correctly reflect the contents. As they are not filled in aerosol dispensers and as the receptacles used exceed the volume limitations for aerosols, they may not be transported as aerosols. The United Nations Sub-Committee of experts on the Transportation of Dangerous goods agreed to create new entries (UN numbers) for these products to address their unique characteristics and corresponding regulations to address the safe transport of such materials.

In this NPRM we are proposing the adoption of entries in the HMT for various chemicals under pressure and the corresponding packaging provisions. In this NPRM, we propose to modify § 173.313 to include the packaging requirements for chemicals under pressure transported in portable tanks. Specifically, we propose to revise the section title, introductory test, and table name to reflect that chemicals under pressure are addressed in this section. We also propose to add table entries for identification numbers UN3500, UN3501, UN3502, UN3503, UN3504 and UN3505. Lastly, we propose to correct the maximum filling density for UN3220.

The addition of packaging requirements specific to chemicals under pressure will ensure that an appropriate level of safety is achieved for these unique materials. PHMSA participated in, and concurs with, the discussions and decisions regarding the packagings selected for these materials. The packagings adopted by the UN, ICAO and IMO provide an appropriate level of safety for these materials and, thus, PHMSA proposes adopting similar packagings in the HMR. Furthermore, aligning with international packaging standards will facilitate the movement of these materials both domestically and internationally.

Section 173.316

Section 173.316 provides the requirements for cryogenic liquids contained in cylinders. Specifically, the HMR requires each cylinder containing cryogenic liquids be equipped with one or more pressure relief devices.

PHMSA proposes to revise § 173.316, “Cryogenic Liquids in Cylinders” to include a requirement consistent with the UN Model Regulations that all pressure relief device inlets must under maximum filling conditions be situated in the vapor space of the closed cryogenic receptacle and the devices must be so arranged as to ensure that the escaping vapor is discharged unobstructed.

This requirement would enhance safety by assisting in the proper function of the pressure release devices. Further, it would prevent unsafe conditions in transport if the liquid form of the gas were released through the pressure release device. For instance, if the gas released is a Division 2.1 (flammable) gas or a Division 2.3 (poisonous) gas, it would reduce the opportunity for the released liquid form of the gas to create an asphyxiant environment through the rapid displacement of the normal concentration of oxygen in the breathable atmosphere. Finally, it would reduce the potential of released cryogenic oxygen in liquid form to create an oxygen enriched atmosphere that may explosively combust.

Section 173.318

Section 173.318 provides the requirements for cryogenic liquids contained in cargo tanks. Specifically, the HMR requires each cargo tanks containing cryogenic liquids be equipped with one or more pressure relief devices.

PHMSA proposes to revise § 173.318, “Cryogenic Liquids in Cargo Tanks” to include a requirement consistent with the UN Model Regulations that all pressure relief device inlets shall under maximum filling conditions be situated in the vapor space of the closed cryogenic receptacle and the devices shall be so arranged as to ensure that the escaping vapor is discharged unobstructed.

This requirement would enhance safety by assisting in the proper function of the pressure release devices. Further, it would prevent unsafe conditions in transport if the liquid form of the gas were released through the pressure release device. For instance, if the gas released is a Division 2.1 (flammable) gas or a Division 2.3 (poisonous) gas, it would reduce the opportunity for the released liquid form of the gas to create an asphyxiant environment through the rapid displacement of the normal concentration of oxygen in the breathable atmosphere. Finally it would reduce the chance of released cryogenic oxygen in liquid form creating an oxygen enriched atmosphere that may explosively combust.

Section 173.335

Section 173.335 is created to provide packaging requirements for new HMT entries “Chemical under pressure n.o.s.” Specifically, PHMSA is proposing the transport requirements, filling limits, minimum service pressure, and periodic inspection requirements for cylinders utilized for shipments of chemical under pressure n.o.s.

Cylinders used to ship chemical under pressure n.o.s. must be authorized UN or DOT cylinders for the propellant and otherwise conform to the applicable requirements of subpart G of part 173.

Section 173.340

Section 173.340 prescribes the packaging requirements for NA1693, tear gas devices. Paragraphs (c) and (d) prescribe the authorized packagings for tear gas devices. In this NPRM, PHMSA is proposing to revise the packaging requirements in paragraphs (c) and (d) by authorizing the use of 4A, 4B, or 4N metal boxes, and 1B2, 1N2, or 1H2 drums.

Part 175 Back to Top

Section 175.8

Section 175.8 provides exceptions from certain regulations for air carrier operator equipment and items of replacement, as well as for items used to provide customer service aboard an aircraft.

ICAO reviewed and revised the Technical Instructions applicable to exceptions from certain regulations for air carrier operator equipment and items of replacement, and to better reflect items that may be sold as part of duty free services. Consistent with the ICAO Technical Instructions, in this NPRM, PHMSA is proposing to revise paragraph (a)(3)(ii) to clarify that wet cell aircraft batteries up to 100 kg net mass per package may be transported. Additionally, lithium ion aircraft batteries in packages containing a single aircraft battery with a net mass not exceeding 35 kg may be transported. Lastly, PHMSA proposes to revise paragraph (b)(2) of this section to add portable electronic devices containing lithium batteries to the list of items permitted aboard an aircraft for use or sale on that specific aircraft.

Section 175.10

Section 175.10 specifies the conditions for which passengers, crew members, or an operator may carry hazardous materials aboard an aircraft. Consistent with revisions to the ICAO Technical Instructions, in this NPRM, PHMSA is proposing to revise paragraph (a)(14), the conditions under which electrically powered heat-producing articles may be carried aboard an aircraft. The requirement that the heat-producing component, or the energy source, must be removed to prevent unintentional functioning during transport is being revised to permit the removal of another component, such as a fuse, to prevent unintentional functioning during transport. In addition the paragraph is being revised to specify procedures for protecting any removed battery from short circuit during transport. PHMSA is also proposing to add paragraphs (a)(20), (a)(21), (a)(22), (a)(23), and (a)(24) to specify conditions under which permeation devices for calibrating air quality monitoring equipment, internal combustion or fuel cell engines, non-infectious specimens, insulated packagings containing refrigerated liquid nitrogen, and small compressed gas cartridges fitted into devices, respectively, may be carried aboard an aircraft.

Part 176 Back to Top

Section 176.2

Section 176.2 provides definitions of terms specifically as they pertain to Part 176. In this NPRM, PHMSA is proposing various revisions to the vessel stowage and segregation requirements specified in Part 176. As part of these changes certain terminology must be defined.

The term “Closed cargo transport unit for Class 1” is defined by the IMDG Code as a freight container or transport vehicle that fully encloses the contents by permanent structures and can be secured to the ship's structure and are, except for the carriage of division 1.4 explosives, structurally serviceable (see § 176.172). Portable magazines conforming to § 176.137 are also considered closed cargo transport units for Class 1. Small compartments such as deck houses and mast lockers are included. Cargo transport units with fabric sides or tops are not closed cargo transport units. The floor of any closed cargo transport unit must either be constructed of wood, close-boarded or so arranged that goods are stowed on sparred gratings, wooden pallets or dunnage. The IMO adopted this new definition for “closed cargo transport unit for Class 1” to define the characteristics required for cargo transport units carrying explosives by vessel.

A new definition for “potential or possible sources of ignition” was adopted by the IMO for incorporation in the next published IMDG Code. The term “Potential or possible sources of ignition” as defined in the IMDG Code “means but is not limited to, open fires, machinery exhausts, galley uptakes, electrical outlets and electrical equipment including those on refrigerated or heated cargo transport units unless they are of a type designed to operate in a hazardous environment. The text “means but is not limited to” indicates that the list of potential or possible sources of ignition is not all inclusive; as it is impossible to identify in a definition all potential or possible sources of ignition that may exist on a variety of vessels with various engineering designs and stowage configurations. Adoption of this definition will provide guidance to vessel stowage planners in determining safe stowage locations for cargo on board vessels.

The term “Protected from sources of heat” as defined by the IMDG Code means “that packages and cargo transport units must be stowed at least 2.4 m from heated ship structures, where the surface temperature is liable to exceed 131 °F (55 °C). Examples of heated structures are steam pipes, heating coils, top or side walls of heated fuel and cargo tanks, and bulkheads of machinery spaces. In addition, packages not loaded inside a cargo transport unit and stowed on deck must be shaded from direct sunlight. The surface of a cargo transport unit can heat rapidly when in direct sunlight in nearly windless conditions and the cargo may also become heated. Depending on the nature of the goods in the cargo transport unit and the planned voyage precautions must be taken to ensure that exposure to direct sunlight is reduced”. This definition was adopted by the IMO for inclusion in the next IMDG Code to provide a list of possible sources of heat a cargo transport unit might encounter during vessel transport. This definition also includes requirements for break bulk packages stowed on deck that are required to be protected from sources of heat by means of a stowage provision or a general stowage requirement found in Part 176.

Therefore, in the NPRM PHMSA proposes to add definitions in this section for the terms, “Closed cargo transport unit for Class 1,” “Potential or possible sources of ignition” and “Protected from sources of heat” with additional text clarifying that a portable magazine conforming to § 176.137 is also considered “closed cargo transport unit for Class 1.”

Section 176.63

Section 176.63 prescribes supplementary requirements with respect to the stowage of specific hazardous materials in addition to those authorized in the HMT in § 172.101. This section sets forth the basic physical requirements for the authorized vessel stowage locations.

In this NPRM PHMSA proposes to revise paragraph (b) of this section by replacing the phrase “shade from radiant heat” with the phrase “protected from sources of heat.” This revision of terminology is necessary to incorporate other proposed changes to the vessel stowage codes in Column 10 B of the HMT proposed in this NPRM.

In this NPRM PHMSA also proposes changes to paragraph (e) of this section, as the definition of “closed cargo transport unit for Class 1” was added to § 176.2 references to magazine stowage type A and C are no longer needed in this section.

Paragraph (e) also contains an exception for empty packages containing residue (excluding Class 2.3 empty packages containing residue and waste aerosols), including IBCs and large packages to be stowed on deck, or under deck if in a mechanically ventilated cargo space. This exception would apply regardless of the stowage provisions indicated in § 172.101(k). PHMSA believes the reduced hazard present in empty packages containing residue combined with the mechanically ventilated cargo space warrants a relaxation of stowage requirements for shipments of empty packages (excluding Class 2.3 and waste aerosols) that otherwise would require on deck stowage.

Section 176.76

Section 176.76 specifies the requirements for transport vehicles, freight containers, and portable tanks containing hazardous materials transported via vessel. Currently paragraph (a)(9) of this section states that when security devices, beacons or other tracking or monitoring equipment are used, they must be securely installed and must be of a certified safe type for the hazardous materials that will be carried within the freight container or transport vehicle in which such as device or equipment is installed.

In this NPRM PHMSA proposes to replace the existing text in paragraph (a)(9) with new text requiring that banding or securing straps used to secure packages must not be over tightened to cause damage or deformation of the packages or the securing points within the freight container or transport vehicle. PHMSA proposes this change to harmonize cargo securement requirements in the HMR with recently adopted changes in the IMDG Code. This requirement is intended to prevent undue stress and potential damage to packages and tie down points during transport.

Section 176.83

Section 176.83 prescribes the general vessel segregation requirements. Paragraph (m) of this section specifies additional segregation requirements for certain groups of hazardous materials. Paragraph (m)(2) of this section prescribes segregation requirements for materials shipped under n.o.s. entries. Furthermore, paragraph (m)(3) discusses materials that fall outside the defining criteria for hazardous materials, but display chemical properties similar to hazardous materials listed in segregation groups.

In this NPRM PHMSA is proposing to revise paragraph (m)(2) to clarify that the offeror of hazardous materials is responsible for deciding if allocation of a segregation group is appropriate. PHMSA is also proposing to revise paragraph (m)(3) to clarify that the offer of hazardous materials for transportation or the person packing the cargo transport unit is responsible for identifying a relevant segregation group and applying the segregation requirements for that segregation group. These revisions will replace the current term “shipper,” which is not defined in § 171.8, with the terms “offeror” and “person who offers” which are defined terms in § 171.8.

Section 176.84

Section 176.84 prescribes the meanings and requirements for numbered or alpha-numeric stowage provisions for vessel shipments listed in column 10B of the § 172.101 Hazardous Materials Table. The provisions in § 176.84 are broken down into general stowage provisions whose meanings are defined in the “table of provisions” in paragraph (b), and the stowage provisions applicable to vessel shipments of Class 1 explosives defined in the table to paragraph (c)(2).

In this NPRM, PHMSA is proposing to revise stowage provisions 25 and 128 and delete stowage provisions 19, 48, and 50 from the table in paragraph (b). Stowage provision 25 is revised from “Shade from radiant heat” to read “Protected from sources of heat.” Stowage provision 128 is revised from “Stow in accordance with the IMDG Code, Sub-section 7.1.10.3 (incorporated by reference; see § 171.7 of this subchapter)” to read “Stow in accordance with the IMDG Code, Sub-section 7.6.2.7.2 (incorporated by reference; see § 171.7 of this subchapter).” Deleted stowage provision 19 previously read “Protect from sparks and open flames.” Deleted stowage provision 48 previously read “Stow “away from” sources of heat”. Deleted stowage provision 50 previously read “Stow “away from” sources of heat where temperatures in excess of 55 °C (131 °F) for a period of 24 hours or more will be encountered.”

The current stowage provision table in paragraph (b) contains three listings requiring shipments to be either shaded or stowed away from sources of heat. The addition of a standard definition for “protected from sources of heat” to the list of definitions in § 176.2 has rendered stowage provisions 19, 48, and 50 redundant and all HMT listings previously assigned stowage provisions 19 or 48 have been assigned the revised stowage provision 25. Furthermore, no listings in the current HMR are assigned stowage provision 50 therefore we are deleting it and all references to it. The change to stowage provision 128 is proposed to account for a citation change in the newest edition of the IMDG Code.

In this NPRM PHMSA is also proposing to revise explosive stowage provision 26E and delete explosive stowage provisions 7E, 8E, and 20E from the table in paragraph (c)(2). Deleted explosive stowage provision 7E previously read “Stowage category “04” for projectiles or cartridges for guns, cannons or mortars; Stowage category “08” for other types.” Deleted explosive stowage provision 8E previously read “When under deck, special stowage is required.” Deleted explosive stowage provision 20E previously read “Stowage category “03” for projectiles or cartridges for guns, cannons or mortars; Stowage category “07” for other types; magazines must be of steel construction that prevents leakage.” Changes to explosive stowage provisions 7E, 8E, and 20E are necessary to account for revisions to the stowage category definitions proposed in § 172.101(k). Additionally, as a result of the removal of stowage provisions 10 and 13 from § 172.101(k), PHMSA proposes to revise explosive stowage provision 26E in § 176.84. Please see section 172.101 for explosive stowage codes associated with HMT entries previously assigned these explosive stowage provisions and a list of entries these provisions have been removed from.

Section 176.116

Section 176.116 prescribes the general stowage conditions for Class 1 explosive materials. Paragraph (a) of this section prescribes explosive stowage requirements, which take into account heat and sources of ignition. Paragraph (f) of this section prescribes explosives stowage requirements for under deck storage. In this NPRM PHMSA is proposing to revise paragraph (a) to clarify the general stowage conditions for Class 1 materials on board vessels and delete and reserve paragraph (f).

PHMSA proposes to revise paragraph (a)(1) to require explosive materials to be stowed in a cool part of the ship, to be kept as cool as practicable while on board, and to be stowed as far away as practicable from any potential source of heat or ignition. This change is proposed due to the inclusion of a definition for “potential source of heat or ignition” in § 176.2. A new paragraph (a)(2) is proposed requiring Class 1 materials to be stowed away from the side of a ship's side at a distance at least equal to one eighth of the beam of the vessel or 2.4 m (8 feet), whichever is less.

This minimum distance for explosive shipment stowage from the ship's side is proposed to harmonize with a recent change in the IMDG Code and provides an increased level of safety by ensuring explosive shipments are not stowed adjacent to the ships internal structure.

Paragraph (f) previously indicated general stowage provisions for HMT explosive entries stowed under deck and assigned stowage category 09 or 10. The proposed removal of stowage category 09 and 10 make these provisions no longer applicable.

Section 176.128

Section 176.128 defines the varying levels of containment for explosives identified as magazine stowage types “A”, “C,” and “Special Stowage.” The IMO has determined that a distinction between closed cargo transport units and magazines is no longer necessary. PHMSA concurs with the IMO on this issue and, thus, in this NPRM, proposes to delete § 176.128 and reserve it for future use. With the addition of a definition for “closed cargo transport unit for Class 1,” and the requirement for all explosive shipments to be stored at a distance at least equal to one eighth of the beam of the vessel or 2.4 m (8 feet), whichever is less, specific requirements for type A, C, and special magazine stowage are now unnecessary. Note that portable magazines remain authorized by § 176.137 and the definition of “closed cargo transport unit for Class 1.”

Section 176.130

Section 176.130 prescribes requirements for magazine stowage type A. The IMO determined that a distinction between closed cargo transport units and magazines is no longer necessary. PHMSA concurs with the IMO on this issue and thus in this NPRM proposes to delete § 176.130 and reserve it for future use. In general, a magazine is equivalent to a closed cargo transport unit with a wooden floor. Properly packaged and transported packages in a closed cargo transport unit will adequately address safety concerns presented by commodities previously required to be transported in magazine stowage type A.

Section 176.133

Section 176.133 prescribes requirements for magazine stowage type C. The IMO has determined that all explosive shipments must be stored at a distance at least equal to one eighth of the beam of the vessel or 2.4 m (8 feet), whichever is less, thus making the provisions for magazine stowage type C unnecessary. PHMSA concurs with the IMO on this issue and thus in this NPRM proposes to delete § 176.133 and reserve it for future use.

Section 176.134

Section 176.134 prescribes requirements for vehicles carrying Class 1 materials requiring magazine stowage. The removal of magazine stowage definitions and provisions make this section unnecessary. Therefore, in this NPRM PHMSA proposes to delete this section and reserve it for future use.

Section 176.136

Section 176.136 prescribes requirements for special stowage of Class 1 materials. Changes to vessel stowage location codes in § 172.101(k) and the assignment of vessel stowage codes requiring on deck stowage for entries previously authorized special stowage make this section unnecessary. Therefore, in this NPRM PHMSA proposes to delete this section and reserve it for future use.

Section 176.138

Section 176.138 prescribes general requirements for on deck stowage. Paragraph (b) provides general requirements for on deck stowage of explosives. In this NPRM PHMSA proposes to revise this section to require explosives to not be stowed within 6 m (20 feet) of the newly defined term “any potential sources of heat or ignition.” This change is proposed to incorporate a newly defined term in § 176.2.

Section 176.144

Section 176.144 prescribes segregation requirements for Class 1 materials transported by vessel. Paragraph (d) allows materials requiring ordinary stowage (non-magazine stowage) to be stowed in the same magazine as materials requiring magazine stowage. In this NPRM PHMSA proposes to revise paragraph (d) to state that if part of a shipment requires non-metallic lining of closed cargo transport units, Class 1 materials requiring ordinary stowage (stowage not requiring non-metallic lining of closed cargo transport units) may be stowed in the same closed cargo transport unit provided there are no exposed parts of any ferrous metal or aluminum alloy, unless separated by a partition. The removal of sections and requirements for magazine stowage necessitates a change in this section.

Section 176.146

Section 176.146 prescribes segregation requirements for Class 1 materials and non-hazardous goods transported by vessel. Paragraph (a) currently states that Class 1 material need not be segregated from non-hazardous materials except as provided in paragraphs (b) and (c). Paragraph (b) then goes on to state that certain cargo (mail, baggage, and personal effects) may not be stowed in the same compartment as, or in compartments immediately above or below, Class 1 (explosive) materials other than those in compatibility group S. Paragraph (c) states that where Class 1 (explosive) materials are stowed against an intervening bulkhead, any mail on the other side of the bulkhead must be stowed away from it.

In this NPRM, PHMSA proposes to revise paragraphs (a) and (b) and delete and reserve paragraph (c). Specifically, PHMSA proposes to revise paragraph (a) to remove a reference to the removed paragraph (c). PHMSA proposes to revise paragraph (b) to read “readily combustible materials may not be stowed in the same compartment or hold as Class 1 (explosive) materials other than those in compatibility group S.” This change incorporates the adoption by IMO of the defined term “readily combustible material” in 176.2. In this NPRM, PHMSA proposes removing and reserving paragraph (c) as the vast majority of mail is now sent by air and not vessel. A specific requirement for stowage of mail away from the intervening bulkhead between it and Class 1 materials is deemed unnecessary.

Section 176.170

Section 176.170 prescribes requirements for shipments of Class 1 materials in freight containers by vessel. Paragraph (a) states that when Class 1 materials are stowed in a freight container, the freight container, for the purposes of this subpart, may be regarded as a magazine but not as a separate compartment. Paragraph (c) states that freight containers used to transport Class 1 (explosive) materials for which magazine stowage type A is required must have a floor consisting of tightly fitted wooden boards, plywood or equivalent non-metallic material, and a non-metallic lining.

In this NPRM, PHMSA proposes to amend paragraph (a) and delete and reserve paragraph (c). Paragraph (a) would be revised to state that when Class 1 materials are stowed in a freight container, the freight container, for the purposes of this Subpart, may be regarded as a closed transport unit for Class 1 or a magazine but not a separate compartment. This change is being made to incorporate the proposed definition of “closed cargo transport unit for Class 1” and the removal of magazine stowage A, C, and Special Stowage. Paragraph (c) references freight containers used to transport Class 1 (explosive) materials for which magazine stowage type A is required. The removal of a definition for and requirements for magazine stowage type A make this paragraph unnecessary.

Section 176.200

Section 176.200 prescribes general stowage requirements for Class 2 materials transported by vessel. Paragraph (c) of this section prescribes the orientation and outer packaging requirements for cylinders transported by vessel.

In this NPRM, PHMSA proposes revisions to paragraph (c) to clarify that cylinders offered for transport by vessel in a vertical position must be stowed in either a block and cribbed or boxed-in with suitable sound lumber. PHMSA also proposes to replace the word movement with shifting in the requirement for the crib or box bracing to prevent any movement. These revisions are to harmonize with vessel transportation requirements incorporated in the IMDG Code and clarify that cylinders stored in a vertical position must be adequately blocked and braced using sound lumber.

Section 176.210

Section 176.210 prescribes on deck stowage requirements for cylinders transported by vessel. This section currently requires cylinders of Class 2 materials being transported by vessel to be protected from radiant heat, including the direct rays of the sun, by structural erections or awnings.

In this NPRM PHMSA proposes to revise this section by replacing “protected from radiant heat, including the direct rays of the sun, by structural erections or awnings” with the newly defined term “protected from sources of heat.”

Section 176.230

Section 176.230 prescribes stowage requirements for Division 2.1 materials transported by vessel. Currently the HMR requires Division 2.1 materials transported in Specification 106A or 110A multi-unit car tanks must be stowed on deck only, and must be shaded from radiant heat.

In this NPRM, PHMSA proposes to replace the phrase “shaded from radiant heat” with the newly defined “protected from sources of heat.”

Section 176.305

Section 176.305 prescribes stowage requirements for Class 3 materials transported by vessel. Paragraph (a) states that Class 3 flammable or combustible liquids must be kept as cool as reasonably practicable and be stowed away from all sources of heat and ignition.

In this NPRM, PHMSA proposes to revise paragraph (a) to read “a Class 3 (flammable) or combustible liquid must be kept as cool as reasonably practicable, protected from sources of heat, and away from potential sources of ignition.” These changes incorporate the proposed definitions of “protected from sources of heat” and “potential or possible sources of ignition.”

Section 176.400

Section 176.400 prescribes stowage requirements for Division 1.5, Class 4 (flammable solids) and Class 5 materials transported by vessel. Paragraph (a) requires Class 4 (flammable solid) material and Division 5.2 (organic peroxide) materials to be kept as cool as reasonably practicable and be stowed away from all sources of heat and ignition.

In this NPRM, PHMSA proposes to revise paragraph (a) to read “Class 4 (flammable solid) material and Division 5.2 (organic peroxide) material must be kept as cool as reasonably practicable, protected from sources of heat, and away from potential sources of ignition.” These changes incorporate the proposed definitions of “protected from sources of heat” and “potential or possible sources of ignition.”

Paragraph (b) of this section requires Division 5.2 (organic peroxide) material to be stowed away from living quarters or access to them. Division 5.2 (organic peroxide) substances not requiring temperature control should be protected from radiant heat, which includes direct rays of the sun, and stowed in a cool, well-ventilated area.

In this NPRM, PHMSA proposes to amend paragraph (b) to replace “should be protected from radiant heat, which includes direct rays of the sun, and stowed in a cool, well-ventilated area” with “must be protected from sources of heat, including radiant heat and strong sunlight, and must be stowed in a cool, well-ventilated area.” These changes are being made to incorporate the proposed definitions of “protected from sources of heat” harmonize with the IMDG Code, and to emphasize that protecting shipments of organic peroxides not requiring temperature control from sources of heat is a requirement and not optional.

Section 176.600

Section 176.600 prescribes detailed requirements for Division 2.3 (Poisonous Gas) and Division 6.1 (Poisonous) materials transported by vessel. Paragraph (d) of this section requires each package of Division 2.3 (poisonous gas) material or Division 6.1 (poison) material that also bears a FLAMMABLE LIQUID or FLAMMABLE GAS label must be stowed in a mechanically ventilated space, kept as cool as reasonably practicable, and be stowed away from all sources of heat and ignition.

In this NPRM, PHMSA proposes to revise paragraph (d) to replace “stowed away from all sources of heat and ignition” with “protected from sources of heat and stowed away from potential sources of ignition.” These changes incorporate the proposed definitions of “protected from sources of heat” and “potential or possible sources of ignition.”

Section 176.907

Section 176.907 is created to incorporate cargo transport requirements for shipments of UN2211, Polymeric Beads, Expandable evolving flammable vapor and UN3314, Plastics Molding Compound in dough, sheet or extruded rope form, evolving flammable vapor. Several cases of damage to cargo transport units were presented to the IMO with the root cause being identified as the release of flammable pentane gas during transportation of shipments UN2211 and UN3314. To address the concerns presented by off gassing of flammable vapors which lead to a rise in pressure that may damage cargo transport units, the IMO instituted measures to ensure an adequate exchange of air within the cargo transport unit is provided. PHMSA proposes to harmonize with recent changes to the IMDG as well as to address safety concerns presented by the off gassing of flammable vapors from shipments of UN2211 and UN3314 by requiring that when UN2211 or UN3314 are transported by vessel, the cargo transport unit must provide an adequate exchange of air. This adequate exchange of air may be accomplished by using a ventilated container, an open-top container, or a container in one door off operation. As an alternative to these methods of air exchange, shippers may transport these cargos under temperature control in refrigerated cargo transport units. Exceptions to the cargo transport unit providing an adequate exchange of air requirement are provided for shipments packed in hermetically sealed packagings, IBCs which conform to the packing group II performance level for liquid dangerous goods, and packagings or IBCs in which the total pressure in the package (i.e., the vapor pressure of the liquid plus the partial pressure of air or other inert gasses less 100 kPa (15 psia)) with a filling temperature of 15 °C (131 °F) does not exceed two-thirds of the marked test pressure. Cargo transport units containing shipments of UN2211 or UN3314 must be marked with a warning mark including the words “CAUTION- MAY CONTAIN FLAMMABLE VAPOR” or “CAUTION- MAY CONTAIN FLAMMABLE VAPOUR” with lettering not less than 25 mm high. This mark must be affixed at each access point in a location where it will be easily seen by persons prior to opening or entering the cargo transport unit and must remain on the cargo transport unit until the cargo transport unit has been completely ventilated to remove any hazardous concentration of vapor or gas, the immediate vicinity of the cargo transport unit is clear of any source of ignition, and the goods have been unloaded.

Part 178 Back to Top

Section 178.512

Section 178.512 prescribes the standards, packaging identification codes, and construction requirements for steel and aluminum boxes (4A and 4B boxes). To incorporate the authorization for use of 4N boxes (metal other than steel or aluminum), the title of the section would be revised to “Standards for steel, aluminum or other metal boxes.” Section 178.512 is also revised to include the authorized packaging identification code, 4N, for other metal boxes, and expand the construction requirements of the section to include these packagings. Subsequent changes will be made throughout the section to address the inclusion of 4N other metal boxes.

Section 178.603

Section 178.603 prescribes the drop test requirements for non-bulk packagings in the HMR. Section 178.603 provides that a drop test must be conducted for the qualification of all packaging design types, and further provides that exceptions for the number of steel and aluminum packaging samples used for conducting the drop test are subject to the approval of the Associate Administrator. Currently, paragraph (a) of this section contains a table that outlines specific types of packagings and the corresponding number of samples that should be tested and the drop orientation of those samples. In this NPRM, PHMSA is proposing to revise this table by including “other metal boxes” to the listed packagings. To incorporate the authorization for use of 4N boxes (metal other than steel or aluminum), § 178.603 is revised to require the drop test for other metal (4N) boxes, and authorize exceptions, subject to the approval of the Associate Administrator, for the number of samples used for conducting the drop test of these packagings.

Section 178.705

Section 178.705 prescribes standards for metal IBCs. Paragraph (a)(3) indicates that IBC specifications 31A, 31B, and 31N are authorized for both liquids and solids. PHMSA is proposing to revise this sentence editorially by removing the authorization to package solids in specification 31 IBCs as the specification is only assigned to liquid substances. This editorial change is consistent with the § 172.102 IBC Code Table revisions in paragraph (c)(4) and other IBC standards (e.g., § 178.707(a)(5)) prescribed in subpart N of part 178.

Section 178.910

Section 178.910 prescribes the marking requirements for specification Large Packaging design types. Paragraph (a)(1) of this describes the size specifications and format of the marking requirements. In this NPRM PHMSA is proposing to clarify these requirements by indicating that for large packages manufactured after January 1, 2014 the minimum marking size must be 12 mm in height.

Furthermore, paragraph (b) of this section is now reserved. However, we are proposing to add a paragraph (b) indicating that for all Large Packages manufactured, repaired or remanufactured after January 1, 2015 the large package must be marked with the symbol applicable to a Large Package designed for stacking or not designed for stacking, as appropriate. This language will be accompanied by an example of such a mark.

Section 178.980

Section 178.980 prescribes the procedures for conducting the stacking test for qualification of all Large Packaging design types. Paragraph (e)(1) describes the criterion a metal or rigid plastic Large Packaging must meet to be considered as successfully passing the stacking test. While paragraph (e) addresses metal or rigid plastic Large Packagings, the criterion that a fiberboard or wooden Large Packaging must meet to be considered as successfully passing the stacking test is omitted.

Therefore, in this NPRM, we propose to correct this omission, by adding a new paragraph (e)(2) that addresses the criterion for fiberboard or wooden Large Packagings to pass the test and redesignating the following paragraphs accordingly.

Subpart R Back to Top

Currently, the HMR do not contain specifications for FBCs. In this NPRM, PHMSA is proposing to adopt the specification, construction, and testing requirements for FBCs. On February 2, 2010, PHMSA published a final rule in the Federal Register under Docket Number PHMSA-2006- 25736 (HM-231) [75 FR 4699] entitled “Hazardous Materials; Miscellaneous Packaging Amendments.” In HM-231, specification and testing requirements were adopted for Large Packagings. The specification and testing requirements for FBCs proposed in this NPRM are modeled on the regulatory structure adopted for Large Packagings in HM-231. Thus, new subpart R of part 178 entitled “Subpart R—Flexible Bulk Container Standards” is proposed.

Section 178.1000

PHMSA proposes to adopt new § 178.1000 entitled “Purpose and scope.” This section prescribes the packaging designs to which Subpart R applies and the location in the HMR where terms used in the subpart are defined.

Section 178.1005

In this NPRM, PHMSA proposes to add new § 178.1005 entitled “Flexible Bulk Container Identification Code.” This section provides the identification code (i.e. BK3) assigned to FBCs.

Section 178.1010

In this NPRM, PHMSA proposes to add new § 178.1010 entitled “Marking of Flexible Bulk Containers.” This section prescribes the markings the manufacturer of an FBC must mark on a package to indicate the FBC meets the specification. The proposed marking requirements for FBCs are based on the current marking requirements for IBCs prescribed in § 178.703.

Section 178.1015

In this NPRM, PHMSA proposes to add new § 178.1015 entitled “General Flexible Bulk Container Standards.” This section prescribes the general packaging integrity requirements an FBC design must meet.

Section 178.1020

In this NPRM, PHMSA proposes to add new § 178.1020 entitled “Period of use for transportation of hazardous materials in Flexible Bulk Containers.” This section prescribes the length of time an FBC may be used to package hazardous materials. Specifically, this section states that an FBC used to package hazardous materials may remain in service not to exceed two years from the date of manufacture.

Subpart S Back to Top

Currently, the HMR do not prescribe testing criteria for FBCs. In this NPRM, PHMSA is proposing to adopt testing protocol for FBCs. On February 2, 2010, PHMSA published a final rule in the Federal Register under Docket Number PHMSA-2006-25736 (HM-231) [75 FR 4699] entitled “Hazardous Materials; Miscellaneous Packaging Amendments.” In HM-231, specification and testing requirements were adopted for Large Packagings. The test protocol proposed in this NPRM for FBCs is modeled on the regulatory structure adopted for Large Packagings in HM-231. Thus, new subpart S of part 178 entitled “Subpart S—Testing of Flexible Bulk Container Standards” is proposed.

Section 178.1030

In this NPRM, PHMSA proposes to adopt § 178.1030 entitled “Purpose and scope.” This section prescribes the applicability to which the Subpart S tests apply.

Section 178.1035

In this NPRM, PHMSA proposes to adopt § 178.1035 entitled “General requirements.” This section prescribes the general packaging requirements for FBCs and addresses the following topics: FBC-related definitions; defining responsibility for compliance with specification requirements; design qualification testing; periodic design testing; proof of compliance; and record retention.

Section 178.1040

In this NPRM, PHMSA is proposing to adopt test preparation requirements for FBCs in new § 178.1040 entitled “Preparation of Flexible Bulk Containers for Testing.” This section specifies the general test preparation requirements applicable to all tests an FBC is required to successfully pass.

Section 178.1045

In this NPRM, PHMSA is proposing to adopt requirements for drop tests conducted on FBCs. A drop test is used to measure a packaging's ability to withstand falls from specific heights and is used to determine if a package is suitable to transport hazardous materials. Thus, PHMSA proposes to add a new § 178.1045 entitled “Drop test.” This section prescribes the preparation of test samples, test methods authorized, drop heights, and criteria for passing the drop test.

Section 178.1050

In this NPRM, PHMSA is proposing to adopt requirements for top lift tests conducted on FBCs. A top lift test measures a package's ability to be moved mechanically by lifting the package by its top end and is used to determine if a package is suitable to transport hazardous materials. Thus, PHMSA proposes to add new § 178.1050 entitled “Top lift test.” This section prescribes requirements for the preparation of test samples, test methods authorized, and criteria for passing the top lift test.

Section 178.1055

In this NPRM, PHMSA is proposing to adopt requirements for stacking tests conducted on FBCs. A stacking test is used to measure a packaging's ability to withstand other packages placed on top of it and is used to determine if a package is suitable to transport hazardous materials. Thus, PHMSA proposes to add new § 178.1055 entitled “Stacking test.” This section prescribes requirements for the preparation of test samples, test methods authorized, and criteria for passing the stacking test.

Section 178.1060

In this NPRM, PHMSA is proposing to adopt requirements for topple tests conducted on FBCs. A topple test is used to measure a packaging's ability to withstand tipping of the package and is used to determine if a package is suitable to transport hazardous materials. Thus, PHMSA proposes to add new § 178.1060 entitled “Topple test.” This section prescribes the preparation of test samples, test methods authorized, topple height, and criteria for passing the topple test.

Section 178.1065

In this NPRM, PHMSA is proposing to adopt requirements for righting tests conducted on FBCs. A righting test is used to measure a packaging's ability to withstand lifting from a lying position at a given rate of speed and is used to determine if a package is suitable to transport hazardous materials. Thus, PHMSA proposes to add new § 178.1065 entitled “Righting test.” This section prescribes the preparation of test samples, test methods authorized, and criteria for passing the righting test.

Section 178.1070

In this NPRM, PHMSA is proposing to adopt requirements for tear tests conducted on FBCs. A tear test is used to measure a packaging's ability to withstand shearing and tearing that may be encountered during transportation, such as loading and unloading, and is used to determine if a package is suitable to transport hazardous materials. Thus, PHMSA proposes to add new § 178.1070 entitled “Tear test.” This section prescribes the preparation of test samples, test methods authorized, and criteria for passing the tear test.

VI. Regulatory Analyses and Notices Back to Top

A. Statutory/Legal Authority for This Rulemaking

This proposed rule is published under the following statutory authorities:

1. 49 U.S.C. 5103(b) authorizes the Secretary of Transportation to prescribe regulations for the safe transportation, including security, of hazardous materials in intrastate, interstate, and foreign commerce. This proposed rule amends regulations to maintain alignment with international standards by incorporating various amendments, including changes to proper shipping names, hazard classes, packing groups, special provisions, packaging authorizations, air transport quantity limitations and vessel stowage requirements. To this end, the proposed rule amends the HMR to more fully align them with the biennial updates of the UN Model Regulations, the IMDG Code and the ICAO Technical Instructions.

Harmonization serves to facilitate international commerce; at the same time, harmonization promotes 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 community. Thus, as explained in the corresponding sections above, we are not proposing harmonization with certain specific provisions of the UN Model Regulations, the IMDG Code, and the ICAO Technical Instructions. Moreover, we are maintaining a number of current exceptions for domestic transportation that should minimize the compliance burden on the regulated community. Additionally, the following external agencies were consulted in the development of this rule: U.S. Coast Guard, U.S. Department of Agriculture (USDA), U.S. Department of Energy, U.S. Department of Interior, U.S. Department of Justice.

2. 49 U.S.C. 5120(b) authorizes the Secretary of Transportation to ensure that, to the extent practicable, regulations governing the transportation of hazardous materials in commerce are consistent with standards adopted by international authorities. This rule proposes to amend the HMR to maintain alignment with international standards by incorporating various amendments to facilitate the transport of hazardous material in international commerce. To this end, as discussed in detail above, PHMSA proposes to incorporate changes into the HMR based on the 17th Revised Edition of the UN Model Regulations, Amendment 36-12 to the IMDG Code, and the 2013-2014 ICAO Technical Instructions, which become effective January 1, 2013. The large volume of hazardous materials transported in international commerce warrants the harmonization of domestic and international requirements to the greatest extent possible.

B. Executive Orders 12866 and 13563 and DOT Regulatory Policies and Procedures

This notice is not considered a significant regulatory action under section 3(f) of Executive Order 12866 (“Regulatory Planning and Review”) and, therefore, was not reviewed by the Office of Management and Budget. This notice is not considered a significant rule under the Regulatory Policies and Procedures of the Department of Transportation (44 FR 11034). Additionally, E.O. 13563 (“Improving Regulation and Regulatory Review”) supplements and reaffirms E.O. 12866, stressing that, to the extent permitted by law, an agency rulemaking action must be based on benefits that justify its costs, impose the least burden, consider cumulative burdens, maximize benefits, use performance objectives, and assess available alternatives.

Benefits to Harmonization. In this NPRM, PHMSA is proposing to incorporate by reference the most recent versions of various international hazardous materials standards, including the 2013-2014 ICAO Technical Instructions, Amendment 36-12 to the IMDG Code, and the 17th Revised Edition of the UN Model Regulations. Additionally, PHMSA is proposing to update its incorporation by reference of the Canadian Transportation of Dangerous Goods Regulations to include Amendment 8 (SOR/2011-239) November 9, 2011; Amendment 9 (SOR/2011-60) March 16, 2011; and Amendment 10 (SOR/2011-210) October 12, 2011. Lastly, PHMSA is proposing to adopt updated International Standards Organization (ISO) standards.

The primary benefit of harmonizing the U.S. Hazardous Materials Regulations (HMR) with the international hazardous materials standards noted previously is that it will reduce the regulatory compliance costs faced by U.S. companies. Without harmonization, these companies will be forced to comply with dual systems of regulations, and as a result will incur higher compliance costs than would be encountered under a single regulatory scheme. The benefit of harmonization attributable to this proposed rulemaking is the difference in regulatory compliance costs faced by companies operating under a single regulatory framework instead of multiple regulatory frameworks.

If the U.S. regulations are not harmonized with the international standards mentioned above, we estimate that it will cost U.S. companies an additional $62 million per year to comply with both the HMR and the international standards. Harmonizing the HMR with the international standards, however, will avert these $62 million in additional costs, and these averted costs are therefore considered the primary benefit attributable to this rulemaking.

The $62 million estimate is based on the assumption that in the absence of harmonization both exporters and importers would have to adhere to two separate hazard communication systems, one used for the transportation of materials within the United States and one used for the transportation of materials outside the United States. Exporters would directly incur four different cost elements and would have to pay for (1) Dual labels and safety data sheets, (2) additional training, (3) additional management activities, and (4) additional packaging costs. Foreign producers who ship products to the United States would also incur these four cost elements, and we assume that the foreign producers would pass half of those incurred costs on to U.S. consumers in the form of higher prices.

To develop the $62 million estimate, we estimated the average hazard communication cost per dollar of hazardous materials produced in the United States and then multiplied that cost figure by an estimate of the value of U.S. imports and exports of hazardous materials. In other words, in the absence of harmonization, we assume that companies involved with U.S. foreign trade would have to pay for additional hazard communication requirements for international movements; these companies would have to comply with the HMR communication requirements during domestic legs of the movement and with international standards during legs of the movement outside of the United States.

A proxy for hazard communication costs was obtained from a recent OSHA study looking at the costs for industry to comply with the revised Hazard Communication Standard. [3] The study estimated the total compliance cost to be $201 million per year based on four cost elements: revisions to labels and safety data sheets, additional training, additional management activities, and printing of color packaging. The first three cost elements are relevant for our purposes and totaled $177 million.

To put the $177 million hazard communication cost estimate on a per unit basis, we divided the $177 million by an estimate of the total value of hazardous materials produced in the United States in 2010. The total value of hazardous materials produced in the United States was estimated to be $151 billion. To derive this $151 billion estimate, we summed relevant product values reported in the Census Bureau's Annual Survey of Manufactures: Value of Product Shipments, and then multiplied the result by 12.4 percent—the percentage of shipment values reported to be hazardous products (this parameter was obtained from Table 10 in the Census Bureau's 2007 Commodity Flow Survey for Hazardous Materials). The resulting hazard communication cost per dollar of hazardous materials output was estimated to be $0.001 (or $177 million ÷ $151 billion).

We were not able to identify any comprehensive source on hazardous materials imports and exports and therefore developed estimates for these figures using quarterly trade data from the Bureau of Economic Analysis [4] and data on the transportation of hazardous materials from the Census Bureau's 2007 Commodity Flow Survey. The quarterly trade data on the value of imports and exports—for fuels and lubricants, chemicals, and medicinal/dental/pharmaceutical products—were summed to produce a single annual trade value for 2010 for industries that produce hazardous materials. Before aggregating the import and export values, we reduced the import values by half to take into account the assumption mentioned previously that foreign producers would be able to pass on only half of the additional hazard communication costs to U.S. consumers. Total annual trade for industries that produce hazardous materials was computed to be just over $498 billion in 2010.

We then multiplied this $498 billion trade figure by 12.4 percent, the percentage of output in these industries reported to be hazardous products; this parameter was obtained from Table 10 in the 2007 Commodity Flow Survey for Hazardous Materials. The resulting estimate indicates that approximately $62 billion worth of hazardous materials were involved in international trade with the United States in 2010.

Multiplying the hazard communication cost per dollar of hazardous material output ($0.001) by the value of hazardous materials involved in international trade ($62 billion) results in a hazard communication cost estimate of approximately $62 million per year that companies would have to pay to comply with different regulatory requirements applicable to international movements. Harmonizing the HMR with international standards would make these $62 million in hazard communications costs unnecessary, and therefore is the main benefit attributable to this rulemaking.

Cost of Harmonization. The potential costs of this rulemaking include private sector compliance costs and any costs that can be attributed to a possible reduction in public safety as a result of harmonizing the HMR with international standards. We expect that both of these costs will be negligible. Preliminary estimates suggest that private sector compliance costs associated with complying with the different amendments in the NPRM will be minimal. In terms of costs due to any reduction in public safety as a result of harmonizing the HMR with international standards, PHMSA believes that none of the proposed revisions to the HMR have material safety impacts. We therefore assume that the gross social costs of this NPRM are effectively zero.

Net Benefit. Based on the discussions of benefits and costs provided above the estimated net benefit associated with the international harmonization NPRM (2137-AE87) is nearly $62 million.

C. Executive Order 13132

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

The Federal hazardous material transportation law, 49 U.S.C. 5101-5128, contains an express preemption provision (49 U.S.C. 5125(b)) that preempts State, local, and Indian tribe requirements on certain covered subjects, as follows:

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

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

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

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

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

This proposed rule addresses covered subject items (1), (2), (3), (4) and (5) above and preempts State, local, and Indian tribe requirements not meeting the “substantively the same” standard. This proposed rule is necessary to incorporate changes adopted in international standards, effective January 1, 2013. If the changes in this proposed rule are not adopted in the HMR, U.S. companies, including numerous small entities competing in foreign markets, would be at an economic disadvantage. These companies would be forced to comply with a dual system of regulations. The changes in this proposed rulemaking are intended to avoid this result. Federal hazardous materials transportation law provides at 49 U.S.C. 5125(b)(2) that, if DOT issues a regulation concerning any of the covered subjects, DOT must determine and publish in the Federal Register the effective date of Federal preemption. The effective date may not be earlier than the 90th day following the date of issuance of the final rule and not later than two years after the date of issuance. PHMSA proposes the effective date of Federal preemption be 90 days from publication of a final rule in this matter.

D. Executive Order 13175

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

E. Regulatory Flexibility Act, Executive Order 13272, and DOT Procedures and Policies

The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires an agency to review regulations to assess their impact on small entities, unless the agency determines that a rule is not expected to have a significant impact on a substantial number of small entities. This proposed rule facilitates the transportation of hazardous materials in international commerce by providing consistency with international standards. This proposed rule applies to offerors and carriers of hazardous materials, some of whom are small entities, such as chemical manufacturers, users and suppliers, packaging manufacturers, distributors, and training companies. As discussed above, under Executive Order 12866, the majority of amendments in this proposed rule should result in cost savings and ease the regulatory compliance burden for shippers engaged in domestic and international commerce, including trans-border shipments within North America.

Many companies will realize economic benefits as a result of these amendments. Additionally, the changes effected by this NPRM will relieve U.S. companies, including small entities competing in foreign markets, from the burden of complying with a dual system of regulations. Therefore, we certify that these amendments will not, if promulgated, have a significant economic impact on a substantial number of small entities.

This proposed rule has been developed in accordance with Executive 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

PHMSA currently has approved information collections under Office of Management and Budget (OMB) Control Number 2137-0018, “Inspection and Testing of Portable Tanks and Intermediate Bulk Containers,” and OMB Control Number 2137-0572, “Testing Requirements for Non-Bulk Packages.” This NPRM may result in an increase in the annual burden and costs of both OMB Control Numbers due to the proposed amendments to allow the use of metals other than steel or aluminum for drums and boxes as well as the proposed new Flexible Bulk Container package authorization, which will require package manufacturers to document and maintain package test results, should they elect to manufacture Flexible Bulk Containers.

Under the Paperwork Reduction Act of 1995, no person is required to respond to an information collection unless it has been approved by OMB and displays a valid OMB control number. Section 1320.8(d), title 5, Code of Federal Regulations requires that PHMSA provide interested members of the public and affected agencies an opportunity to comment on information and recordkeeping requests.

This notice identifies revised information collection requests that PHMSA will submit to OMB for approval based on the requirements in this proposed rule. PHMSA has developed burden estimates to reflect changes in this proposed rule, and estimates the information collection and recordkeeping burden as proposed in this rule to be as follows:

OMB Control No 2137-0018
Annual Increase in Number of Respondents 25
Annual Increase in Annual Number of Responses 50
Annual Increase in Annual Burden Hours 200
Annual Increase in Annual Burden Costs $5,000
OMB Control No 2137-0572
Annual Increase in Number of Respondents 100
Annual Increase in Annual Number of Responses 300
Annual Increase in Annual Burden Hours 600
Annual Increase in Annual Burden Costs $15,000

PHMSA specifically requests comments on the information collection and recordkeeping burdens associated with developing, implementing, and maintaining these proposed requirements. Address written comments to the Dockets Unit as identified in the ADDRESSES section of this rulemaking. We must receive comments regarding information collection burdens prior to the close of the comment period identified in the DATES section of this rulemaking. In addition, you may submit comments specifically related to the information collection burden to the PHMSA Desk Officer, Office of Management and Budget, at fax number 202-395-6974. Requests for a copy of this information collection should be directed to Steven Andrews or T. Glenn Foster, Standards and Rulemaking Division (PHH-10), Pipeline and Hazardous Materials Safety Administration, 1200 New Jersey Avenue SE., Washington, DC 20590-0001, Telephone (202) 366-8553. If these proposed requirements are adopted in a final rule, PHMSA will submit the revised information collection and recordkeeping requirements to OMB for approval.

G. Regulation Identifier Number (RIN)

A regulation identifier number (RIN) is assigned to each regulatory action listed in the Unified Agenda of Federal Regulations. The Regulatory Information Service Center publishes the Unified Agenda in April and October of each year. The RIN contained in the heading of this document can be used to cross-reference this action with the Unified Agenda.

H. Unfunded Mandates Reform Act

This proposed rule does not impose unfunded mandates under the Unfunded Mandates Reform Act of 1995. It does not result in costs of $141.3 million or more, adjusted for inflation, to either State, local, or tribal governments, in the aggregate, or to the private sector in any one year, and is the least burdensome alternative that achieves the objective of the rule.

I. Environmental Assessment

The National Environmental Policy Act, 42 U.S.C. 4321-4375, requires that federal agencies analyze proposed actions to determine whether the action will have a significant impact on the human environment. The Council on Environmental Quality (CEQ) regulations require federal agencies to conduct an environmental review considering: (1) The need for the proposed action; (2) alternatives to the proposed action; (3) probable environmental impacts of the proposed action and alternatives; and (4) the agencies and persons consulted during the consideration process. 40 CFR 1508.9(b).

Description of Action

Docket No. PHMSA-2012-0027 (HM-215L), NPRM. The transportation of hazardous materials in commerce is subject to the HMR, issued under authority of Federal hazardous materials transportation law, codified at 49 U.S.C. 5001 et seq. To facilitate the safe and efficient transportation of hazardous materials in international commerce, the HMR provides that both domestic and international shipments of hazardous materials may be offered for transportation and transported under provisions of the international regulations.

Purpose and Need

In this NPRM, PHMSA is proposing to amend the Hazardous Materials 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. These revisions are necessary to harmonize and align the HMR with recent amendments adopted in the UN Model Regulations, IMDG Code, and the ICAO Technical Instructions. The amendments proposed in this notice are intended to facilitate the safe and efficient transportation of hazardous materials in international commerce, provide clarity designed to encourage and increase regulatory compliance, and improve the efficacy of emergency response in the event a hazardous materials incident occurs.

Alternatives

In developing this proposed rule, we considered three alternatives:

(1) Do nothing.

(2) Adopt the international standards in their entirety.

(3) Adopt most of the international standards, with certain modifications based on safety or economic considerations.

Alternative 1:

Because our goal is to facilitate uniformity, compliance, commerce and safety in the transportation of hazardous materials, we rejected this alternative.

Alternative 2:

By adopting the international standards in their entirety, PHMSA could potentially adopt provisions that, in our view, do not provide an adequate level of transportation safety and environmental safety and protection. Further, because we provide for domestic exceptions and extended compliance periods to minimize the potential economic impact of any revisions on the regulated community, this alternative was also rejected.

Alternative 3:

Consistency between U.S. and international regulations helps to assure the safety of international hazardous materials transportation and the environment through better understanding of the regulations, an increased level of compliance, the smooth flow of hazardous materials from their points of origin to their points of destination, and effective emergency response in the event of a hazardous materials incident. Under Alternative 3, we would harmonize the HMR with international standards to the extent consistent with U.S. safety, economic, and environmental protection goals.

Alternative 3 is the only alternative that addresses, in all respects, the purpose of this regulatory action, which is to facilitate the safe and efficient transportation of hazardous materials in international commerce and the protection of the environment. These actions will provide the greatest possible harmonization with international requirements without posing an undue increased cost burden on the regulated community. For these reasons, alternative 3 is our recommended alternative.

Analysis of Environmental Impacts

Hazardous materials are transported by aircraft, vessel, rail, and highway. The potential for environmental damage or contamination exists when packages of hazardous materials are involved in accidents or en route incidents resulting from cargo shifts, valve failures, package failures, or loading, unloading, or handling problems. The ecosystems that could be affected by a release include air, water, soil, and ecological resources (for example, wildlife habitats). The adverse environmental impacts associated with releases of most hazardous materials are short-term impacts that can be greatly reduced or eliminated through prompt clean-up of the accident scene. Most hazardous materials are not transported in quantities sufficient to cause significant, long-term environmental damage if they are released.

The hazardous material regulatory system is a risk-management system that is prevention-oriented and focused on identifying hazards and reducing the probability and quantity of a hazardous material release. Amending the HMR to maintain alignment with international standards enhances the safe transportation of hazardous materials in domestic and international commerce. When considering the adoption of international standards under the HMR, we review and consider each amendment on its own merit and assess the likely impact on transportation safety and the environment. It is our preliminary conclusion that the proposals in this notice will not have either a substantial positive or adverse effect on the environment. Consequently, PHMSA welcomes public comment on the matter.

In this NPRM, PHMSA is proposing the following noteworthy amendments to the HMR:

Chemicals under pressure. Manufacturers in the United Kingdom, the United States, Australia, Canada, and other countries are supplying pressurized products contained and transported in gas cylinders. The products are liquids or solids such as adhesives, coatings and cleaners combined with a gas or gas mixtures in pressure receptacles under sufficient pressure to expel the contents. These mixtures are typically expelled from the pressurized cylinders as foams, streams or thick sprays. Currently the HMR does not comprehensively address chemicals under pressure. Because of the substantial packaging integrity inherent in pressure vessel designs, PHMSA believes the proposed chemical under pressure amendments in this rule will result in a positive environmental impact.

Flexible Bulk Containers (FBCs). Incorporate a new packaging definition, operational controls, performance-oriented standards, and testing requirements for Flexible Bulk Containers (FBCs). FBCs are flexible bulk packages with a capacity over the currently authorized maximum volumetric capacity for flexible IBCs, but not exceeding 15 cubic meters. FBCs provide shippers the opportunity to utilize a reusable flexible packaging for bulk shipments of certain authorized low-hazard commodities, all of which are currently authorized in non-specification bulk bins. Because of the inherent integrity of a specification packaging design when compared to a non-specification packaging design, PHMSA believes the amendments in this proposal authorizing the construction and use of FBCs will result in a net positive environmental impact.

Packaging Authorizations. Part 173 of the HMR prescribes the general requirements for shipment preparation and packaging selection for hazardous materials. Consistent with amendments adopted in the various international standards, we are proposing to amend multiple part 173 packaging sections by authorizing additional packaging specifications used to package hazardous materials. These proposed amendments include, but are not limited to, the authorization to use wood as a material of package construction for certain explosives, the authorization to use metals other than steel or aluminum for boxes and drums for certain hazardous materials, and the incorporation of authorizations and specifications of FBCs. Because of the substantial integrity in the newly authorized packaging specifications, PHMSA believes the amendments in this proposal will result in a positive environmental impact. Higher integrity packaging designs can and do prevent the unintentional release of hazardous materials when transported in commerce.

Vessel Stowage Requirements. The requirements for vessel stowage are described and specified in § 172.101(k) and HMT entries are assigned appropriate vessel stowage codes and stowage special provisions in column 10 of the HMT. We propose to clarify these instructions by revising the vessel stowage location requirements for explosives and reducing the number of explosive stowage categories from 15 to 5 in column 10A of the HMT. Specifically, explosive stowage categories 6 through 15 will be eliminated, and stowage categories 1 through 5 will be retained and modified. We are also proposing modifications to the vessel stowage provisions indicated in column 10B of the HMT. In order to harmonize with the IMDG Code, PHMSA proposes to incorporate the addition of a new definition for protected from sources of heat and potential or possible sources of ignition (see Section 176.2 of this NPRM for definitions), and subsequently revise and delete various vessel stowage provisions.

Because the amendments proposed in this notice reducing and consolidating the number of vessel stowage codes for explosives result in greater clarity of the HMR and reduce the potential of incidents occurring, PHMSA believes they will have a positive impact on the environment.

Conclusion

In this NPRM, PHMSA proposes to amend the HMR in response to revisions adopted in the various international standards. Through this integrated and cooperative approach, we believe we can be most successful in reducing incidents, enhancing public safety, and protecting the environment. The proposed amendments are intended to update, clarify, or provide relief from certain existing regulatory requirements and to provide greater flexibility in packaging selection suitable for the transportation of hazardous materials. PHMSA believes the net environmental impact of this rule will be positive. Additionally, we believe there will be little or no adverse environmental impacts associated with the amendments proposed in this rule. PHMSA solicits public comment on the conclusions made in this preliminary analysis.

K. Executive Order 13609 and International Trade Analysis

Under E.O. 13609, agencies must consider whether the impacts associated with significant variations between domestic and international regulatory approaches are unnecessary or may impair the ability of American business to export and compete internationally. In meeting shared challenges involving health, safety, labor, security, environmental, and other issues, international regulatory cooperation can identify approaches that are at least as protective as those that are or would be adopted in the absence of such cooperation. International regulatory cooperation can also reduce, eliminate, or prevent unnecessary differences in regulatory requirements.

Similarly, the Trade Agreements Act of 1979 (96), as amended by the Uruguay Round Agreements Act (103), prohibits Federal agencies from establishing any standards or engaging in related activities that create unnecessary obstacles to the foreign commerce of the United States. For purposes of these requirements, Federal agencies may participate in the establishment of international standards, so long as the standards have a legitimate domestic objective, such as providing for safety, and do not operate to exclude imports that meet this objective. The statute also requires consideration of international standards and, where appropriate, that they be the basis for U.S. standards.

PHMSA participates in the establishment of international standards to protect the safety of the American public, and we have assessed the effects of the proposed rule to ensure that it does not cause unnecessary obstacles to foreign trade. In fact, the rule is designed to facilitate international trade. Accordingly, this rulemaking is consistent with E.O. 13609 and PHMSA's obligations under the Trade Agreement Act, as amended.
