Proposed Amendment To Hazardous Materials Regulations

The Pipeline and Hazardous Materials Safety Administration (PHMSA) published a notice of proposed rulemaking to amend the Hazardous Materials Regulations (HMR) 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 HMR 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 and subsequently address a petition for rulemaking.

Comments must be received by October 15, 2012.
