Hazardous Materials: Miscellaneous Cargo Tank Motor Vehicle and Cylinder Issues; Petitions for Rulemaking

Notice of proposed rulemaking (NPRM).
PHMSA proposes to amend the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) to revise certain requirements applicable to the manufacture, maintenance, and use of DOT and MC specification cargo tank motor vehicles, DOT specification cylinders and UN pressure receptacles. The proposed revisions are based on petitions for rulemaking submitted by the regulated community and are intended to enhance the safe transportation of hazardous materials in commerce, clarify regulatory requirements, and reduce operating burdens on cargo tank and cylinder manufacturers, requalifiers, carriers, shippers, and users.
