Action
Notice of proposed rulemaking (NPRM).
Summary
RSPA is proposing a number of revisions to the Hazardous Materials Regulations to update and clarify the regulations on the construction and maintenance of cargo tank motor vehicles. This proposed rule also addresses three National Transportation Safety Board (NTSB) recommendations and several petitions for rulemaking. By updating and clarifying the regulations, addressing the NTSB recommendations, and responding to petitions for rulemaking, these revisions should increase the safety of cargo tanks transporting hazardous materials, provide greater flexibility in design and construction of cargo tanks, and reduce operating burdens for owners, operators, and manufacturers of cargo tank motor vehicles.
