**SUPPLEMENTARY INFORMATION:**
ST LNG requests authorization to export domestically produced LNG from its proposed Project to be located at Brazos Block BA-476 in Federal waters in the Gulf of America, offshore of Matagorda, Texas. ST LNG states that the Project will be a deepwater port under the Deepwater Port Act of 1974, as amended. ST LNG seeks to export LNG in a volume equivalent to 460 Bcf/yr of natural gas (equivalent to approximately 8.4 million metric tons per annum) by ocean-going vessel on a non-additive basis to: (i) any country with which the United States has entered into a free trade agreement (FTA) requiring national treatment for trade in natural gas (FTA countries), and (ii) any other country with which trade is not prohibited by U.S. law or policy (non-FTA countries). This Notice applies only to the portion of the Application requesting authority to export LNG to non-FTA countries pursuant to section 3(a) of the NGA. [^1] DOE will review ST LNG's request for authorization to export LNG to FTA countries separately pursuant to NGA section 3(c). [^2]

ST LNG seeks this authorization on its own behalf and as agent for other entities that will hold title to the LNG at the time of export. ST LNG requests the authorization for a term to commence on the date of first export following the commencement of commercial operation of the Project, and to extend through December 31, 2050, plus a three-year Make-Up Period extending through December 31, 2053, consistent with recent DOE practice.
