The Pipeline and Hazardous Materials Safety Administration, in coordination with the Federal Railroad Administration, is proposing a new rule that would authorize the transportation of liquefied natural gas by rail in the DOT-113 tank cars. Currently LNG is only permitted to be transported by rail in portable tanks with authorization from FRA. The current HMR does not authorize DOT 113 tank cars to transport other flammable cryogenic liquids. It was specifically designed for refrigerated liquified gases but it was determined that the design specification may be similarly suitable for LNG. The proposed rule is seeking comments on changes to the Hazardous Materials Regulations regarding the transportation of LNG by rail in the DOT-113 specification tank cars.
Skip Elliott, PHMSA Administrator, said “Safety is the number one priority of PHMSA and we understand the importance and will make it a top priority to evaluate all public comments and concerns raised throughout the rulemaking process. This major rule will establish a safe, reliable, and durable mode of transportation for LNG, while substantially increasing economic benefits and our nation’s energy competitiveness in the global market.”
FRA Administrator, Ronald Batory, went on to say “FRA shares regulatory oversight responsibility for the safe transportation of hazardous materials by rail. This rulemaking is consistent with our systemic approach to accident prevention, mitigation, and emergency response preparedness.”
