Transportation of Hazardous Materials; Unloading of Intermodal (IM) Portable Tanks on Transport Vehicles
Notice of proposed rulemaking (NPRM).
RSPA proposes to amend the Hazardous Materials Regulations to permit, for an interim period and subject to certain unloading conditions, the unloading of intermodal (IM) portable tanks transporting certain liquid hazardous materials that are not equipped with a thermal means of remote activation of the internal self-closing stop-valves fitted on the bottom discharge outlets. Permitting such unloading for an interim period would afford operators time to bring the IM portable tanks into conformance with the regulations.
