PHMSA wetlines reg proposal goes to OMB

The Pipeline and Hazardous Materials Safety Administration reportedly has sent its notice of proposed rulemaking (NPRM) for banning wetlines on tank trailers to the Office of Management and Budget, according to National Tank Truck Carriers and the American Trucking Associations.

Details of the NPRM have not been released, and it is not known how broad the ban on external product piping might be. Typically, the NPRM should be published in the Federal Register within the next 90 days.
