Pipeline and Hazardous Materials Safety Administration May 25, 2012 – Federal Register Recent Federal Regulation Documents

This document responds to administrative appeals and solicits public comment on proposals generated as a result of certain amendments adopted in an international harmonization final rule published in the Federal Register. The final rule amended the Hazardous Materials Regulations (HMR) by revising, removing or adding proper shipping names, the hazard class of a material, packing group assignments, special provisions, packaging authorizations, packaging sections, air transport quantity limitations, and vessel stowage requirements. The amendments were necessary to align the HMR with recent revisions to international standards for the transport of hazardous materials by all modes. In this notice, PHMSA proposes to amend the HMR as a result of administrative appeals submitted in response to various amendments adopted in the January 19, 2011 final rule. This document also addresses recent actions taken by the International Civil Aviation Organization's (ICAO) Dangerous Goods Panel (DGP) regarding certain lithium ion battery-powered mobility aids (e.g., wheelchairs, travel scooters) offered by passengers for air transport. Further, this notice proposes amendments to the HMR as a result of two administrative appeals submitted by an appellant in response to a final rule published in the Federal Register, that revised shipper responsibilities related to packaging design variation, manufacturer notification, and recordkeeping requirements for certain packaging types.
