Pipeline and Hazardous Materials Safety Administration December 23, 2010 – Federal Register Recent Federal Regulation Documents

PHMSA is considering amending the Hazardous Materials Regulations (HMR) to incorporate the most recent edition of the American Society of Mechanical Engineers' Boiler and Pressure Vessel Code, Section XII for the design, construction, and certification of cargo tank motor vehicles, cryogenic portable tanks and multi-unit-tank car tanks (ton tanks). PHMSA is also considering incorporating by reference the National Board of Boiler and Pressure Vessel Inspectors' National Board Inspection Code as it applies to the continuing qualification and maintenance of ASME stamped cargo tank motor vehicles, portable tanks, and multi-unit-tank car tanks (ton tanks) constructed to standards in ASME Section VIII or ASME Section XII. In this ANPRM, PHMSA is soliciting comments on the advisability of incorporating the most recent editions of these two standards by reference. We request comments to identify any gaps or inconsistencies between current HMR requirements and these consensus standards. Additionally, we seek input regarding any potential costs, benefits, and burdens associated with compliance with these consensus standards.
