Hazardous Materials: Revision and Reformatting of Requirements for the Authorization To Use International Transport Standards and Regulations

In this final rule, PHMSA is amending the Hazardous Materials Regulations to revise and consolidate the requirements applicable to the use of the International Civil Aviation Organization's Technical Instructions for the Safe Transport of Dangerous Goods by Air, the International Maritime Dangerous Goods Code, Transport Canada's Transportation of Dangerous Goods Regulations, and the International Atomic Energy Agency's Safety Standards Series: Regulations for the Safe Transport of Radioactive Material. The revisions and reformatting provide a user-friendly format to promote understanding of the conditions and limitations on the use of international standards and regulations. In addition, PHMSA is authorizing the use in domestic transportation of portable tanks, cargo tank motor vehicles, and rail tank cars manufactured in accordance with Transport Canada's Transportation of Dangerous Goods Regulations. The amendments adopted in this final rule maintain the high transportation safety standard established under the Hazardous Materials Regulations.
