Pipeline and Hazardous Materials Safety Administration January 8, 2015 – Federal Register Recent Federal Regulation Documents

PHMSA is amending 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 the Hazardous Materials Regulations with recent changes made to the International Maritime Dangerous Goods (IMDG) Code, the International Civil Aviation Organization's Technical Instructions (ICAO TI) for the Safe Transport of Dangerous Goods by Air, the United Nations Recommendations on the Transport of Dangerous Goods (UN Model Regulations) and subsequently address three petitions for rulemaking.
