The details of this news item are listed in the US Federal Register Vol. 76 No. 12 and US Department of Transportation Pipeline and Hazardous Materials Safety Administration (PHMSA).
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 limited quantities, and vessel stowage requirements. These revisions are necessary to harmonize the Hazardous Materials Regulations with recent changes made to the International Maritime Dangerous Goods Code, the International Civil Aviation Organization’s Technical Instructions for the Safe Transport of Dangerous Goods by Air, and the United Nations Recommendations on the Transport of Dangerous Goods—Model Regulations.
PHMSA has long recognized the need to authorize limited exceptions for the transportation of classes and quantities of hazardous materials described as limited quantities, or consumer commodities reclassed as ORM–D. Considerable efforts have been made internationally to harmonize multi- modal standards with regard to the transport of limited quantities, including consumer commodities.
