The U.S. Department of Transportation’s Research and Special Programs Administration has proposed various revisions to the regulations governing construction and maintenance of cargo tank motor vehicles. RSPA says the proposal 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. Comments on the proposal are due Feb. 4. For a copy of the proposal, visit and search Docket No. 3554.
