PHMSA Provides Formal Interpretations to Downeast LNG Regarding Exclusion Zone Calculation, Jetting and Flashing

Last Friday, the U.S. Pipeline and Hazardous Materials Safety Administration (PHMSA) provided formal guidance on two questions submitted by Downeast LNG. First, PHMSA concluded that Downeast LNG may use the DLNG Source Term Model to calculate the vapor-gas exclusion zone for the sumps proposed for the Downeast LNG facility. Second, contrary to Downeast LNG’s assertions, PHMSA concluded that Downeast LNG must analyze the potential effects of flashing and jetting in its siting analysis for its LNG regasification terminal.
