FERC issues draft EIS on Corpus Christi LNG project

LNG Industry,

The Federal Energy Regulatory Commission (FERC) has prepared a draft environmental impact statement (EIS) for the Corpus Christi LNG project in Texas.

The project is proposed by Corpus Chrisit Liquefaction LLC, and Cheniere Corpus Christi Pipeline, L.P. (Cheniere). The project’s land-based facilities are located in San Patricio County, Texas, with the marine facilities located in Nueces County, Texas.

LNG facilities

The project would enable Cheniere to export 782 million British thermal units (MMBtu) per year of LNG and import sufficient LNG volume to send out 400 MMBtu per day of natural gas. The proposed facilities associated with the LNG terminal include:

  • Liquefaction facilities, including three liquefaction trains capable of producing 782 MMBtu per year of LNG
  • Vaporisation facilities, including two trains of ambient air vaporisers (AAV) and send out pumps capable of vaporising sufficient LNG volume for each to send out 200 MMBtu per day of natural gas
  • LNG storage facilities, including three LNG storage tanks each capable of storing 160 000 m3 of LNG
  • Marine terminal facilities with two LNG carrier berths.

The project would also include 23 miles of new 48-in. diameter natural gas pipeline and two compressor stations which total 53 260 horsepower. Cheniere would install additional ancillary facilities along the pipeline including six meter stations, five mainline valves, and a pig launcher and receiver.

Draft EIS

The draft EIS has been prepared in compliance with the requirements of the National Environmental Policy Act (NEPA), the Council on Environmental Quality regulations for implementing NEPA, and FERC regulations implementing NEPA.

The US Army Corps of Engineers, US Coast Guard, US Department of Transportation, US Environmental Protection Agency, and US Department of Energy served as cooperating agencies in the preparation of this draft EIS.

Project approval

The FERC concluded that approval of the proposed project, with appropriate mitigating measures in the draft EIS, would ensure that impacts in the project area would be avoided or minimised and would not be significant.

Construction and operation of the project would result in mostly temporary and short-term environmental impacts, although some long-term and permanent environmental impacts would occur. Potential impacts would be reduced with the implementation of Cheniere’s proposed minimisation and mitigation measures and an additional 108 measures recommended in the draft EIS.
