Hazardous Materials: FAST Act Requirements for Flammable Liquids and Rail Tank Cars
The Pipeline and Hazardous Materials Safety Administration is issuing this final rule to codify in the Hazardous Materials Regulations certain mandates and minimum requirements of the FAST Act. Specifically, the FAST Act mandates a revised phase-out schedule for all DOT Specification 111 tank cars used to transport unrefined petroleum products (e.g., petroleum crude oil), ethanol, and other Class 3 flammable liquids. The FAST Act also requires that each tank car built to meet the DOT Specification 117 and each non-jacketed tank car retrofitted to meet the DOT Specification 117R be equipped with a thermal protection blanket that is at least \1/2\-inch thick and meets existing thermal protection standards. Further, the FAST Act mandates minimum top fittings protection requirements for tank cars retrofitted to meet the DOT Specification 117R.
