Hazardous Materials Regulations: Combustible Liquids

Advance notice of proposed rulemaking (ANPRM).

PHMSA is considering amendments to the Hazardous Materials Regulations (HMR) as they apply to the transportation of combustible liquids. Specifically, we are considering whether to harmonize the domestic regulations applicable to the transportation of combustible liquids with international transportation standards. In addition, we are examining ways to revise, clarify, or relax certain regulatory requirements to facilitate the transportation of these materials while maintaining an adequate level of safety. The intent of this ANPRM is to invite public comments on how to accomplish these goals, provide an opportunity for comment on amendments PHMSA is considering, and present a forum for the public to offer additional recommendations for the safe transportation of combustible liquids.
