Action
Final rule.
Summary
RSPA is adopting 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 final rule also addresses three National Transportation Safety Board (NTSB) recommendations and several petitions for rulemaking. These revisions will 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.
