The Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (PHMS A) has issued a notice of proposed rulemaking to amend the Hazardous Materials Regulations (HAZMAT) to align with revised international standards. The proposed rules would “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.” According to the agency, “[i]f the amendments in this proposed rule are not adopted by January 1, 2013, the date most of the international standards above take effect, U.S. companies . . . would be at an economic disadvantage” because they would have to comply with “a dual system of regulations.”  

The proposed rule would incorporate new International Organization for Standardization standards and implement provisions of the 2013–2014 International Civil Aviation Organization Technical Instructions for the Safe Transport of Dangerous Goods by Air, Amendment 36–12 to the International Maritime Dangerous Goods Code, and the 17th Revised Edition of the United Nations Recommendations on the Transport of Dangerous Goods. The proposal would also update PHMS A’s incorporation by reference of the Canadian Transportation of Dangerous Goods Regulations to include Amendments 8, 9 and 10. Comments must be submitted within 60 days of publication in the Federal Register.
