The ST LNG Deepwater Port license application describes a project located approximately 10.4 nautical miles (19.2 kilometers) offshore Matagorda, Texas, in approximately 65 to 72 feet of water. The FEIS analyzes the potential environmental impacts of the proposed project and reasonable alternatives, including the no action alternative. The FEIS will inform MARAD's decision to approve, approve with conditions, or disapprove the ST LNG Deepwater Port license application.
