PHMSA is proposing to amend the Hazardous Materials Regulations applicable to the design, construction, certification, recertification and maintenance of cargo tank motor vehicles, cryogenic portable tanks and multi-unit tank car tanks (ton tanks) in response to petitions for rulemaking from the American Society of Mechanical Engineers (ASME), the National Board of Boiler and Pressure Vessel Inspectors (National Board), and the Pressure Vessel Manufacturers Association (PVMA). Specifically, this NPRM proposes to allow the use of the 2013 edition of the ASME's Boiler and Pressure Vessel Code, Section XII (Section XII) for the design, construction, and certification of cargo tank motor vehicles, cryogenic portable tanks and ton tanks. PHMSA also proposes to authorize the use of the 2013 edition of the National Board of Boiler and Pressure Vessel Inspectors' National Board Inspection Code (NBIC), as it applies to the continuing qualification and maintenance of ASME constructed cargo tank motor vehicles, cryogenic portable tanks, and ton tanks constructed to standards in ASME's Section XII, and existing cargo tank motor vehicles and portable tanks constructed to Section VIII, Division 1. If adopted, these amendments will allow for regulatory flexibility, without compromising safety.
