Hazardous Materials: Liquefied Natural Gas by Rail

FR Abstract
PHMSA, in coordination with the Federal Railroad Administration (FRA), is amending the Hazardous Materials Regulations (HMR) to allow for the bulk transport of ``Methane, refrigerated liquid,'' commonly known as liquefied natural gas (LNG), in rail tank cars. This rulemaking authorizes the transportation of LNG by rail in DOT-113C120W specification rail tank cars with enhanced outer tank requirements, subject to all applicable requirements and certain additional operational controls. The enhancements to the outer tank are indicated by the new specification suffix ``9'' (DOT-113C120W9).
