Today, the US Pipeline and Hazardous Materials Safety Administration published in the Federal Register a Final Rule titled Hazardous Materials: Liquefied Natural Gas by Rail [Docket No. PHMSA-2018-0025 (HM-264)]. As reported in alert 2020-41 on June 25, 2020, PHMSA previously released the Final Rule in pre-publication form. HM-264 amends 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” (DOT113C120W9).
View the Final Rule in the Federal Register. It will become effective August 24, 2020, though voluntary compliance is immediately authorized. Public comments are open and can be submitted via Regulations.gov. We recommend readers login to hazmatship.com to review our prior articles on the topic of LNG by rail:
