Liquefied Natural Gas by Rail: Policy Issues [November 18, 2019]   [open pdf - 728KB]

From the Document: "On October 24, 2019, the Pipeline and Hazardous Materials Safety Administration (PHMSA), in coordination with the Federal Railroad Administration (FRA), published a proposed rule to authorize the transportation of liquefied natural gas (LNG) in rail tank cars. This publication was the latest federal action intended to provide 'greater flexibility in the modes of transportation' of LNG to serve domestic and export markets. The proposed rule could conflict with legislation approved by the House of Representatives earlier this year. Natural gas cooled below -260° F at normal atmospheric conditions condenses into a liquid with 1/600th of its gaseous volume. In this form, it can be economically transported in insulated tanks. When LNG is warmed it 'regasifies' and is used the same way as natural gas supplied by pipeline. Like other gaseous or vaporized fuels, natural gas is combustible, so an uncontrolled release of LNG poses a risk of fire or, in confined spaces, explosion. Due to its low temperature, LNG also could injure people or damage facilities through direct contact. Partly because of these safety risks, LNG shipment and the development of related facilities have been controversial in some communities."
