The U.S. Coast Guard (USCG), in coordination with the Maritime Administration (MARAD), will prepare an Environmental Impact Statement (EIS) as part of the environmental review of the Grand Isle LNG Operating Company, LLC (Applicant) deepwater port license application. The application proposes the ownership, construction, operation, and eventual decommissioning of an offshore natural gas export deepwater port, known as the Grand Isle LNG Export Deepwater Port Development Project, that would be located in Federal waters approximately 11.3 nautical miles (13 statute miles, or 20.9 kilometers) offshore Plaquemines Parish, Louisiana in a water depth of approximately 68 to 72 feet (20.7 to 21.9 meters). The deepwater port would allow for the loading of LNG trading carriers.
