Tennessee Gas Pipeline Company, LLC and Southern Natural Gas Company, LLC; Notice of Availability of the Final Environmental Impact Statement for the Proposed Evangeline Pass Expansion Project

The staff of the Federal Energy Regulatory Commission (FERC or Commission) has prepared a final environmental impact statement (EIS) for the Evangeline Pass Expansion Project (Project), proposed by Tennessee Gas Pipeline Company, LLC (Tennessee) and Southern Natural Gas Company, LLC (SNG) in the above-referenced dockets.

Tennessee requests authorization to construct and operate about 13 miles of 36-inch-diameter pipeline and a new compressor station in St. Bernard and Plaquemines Parishes, Louisiana. SNG requests authorization to construct and operate a new compressor station and three new meter stations in Clarke and Smith, Counties, Mississippi; and St. Bernard Parish, Louisiana. The Project would enable the transportation of up to 1,100,000 dekatherms per day of natural gas to an interconnect with Venture Global Gator Express, LLC's Gator Express Pipeline to provide feed gas for Venture Global Plaquemines LNG, LLC's facility in Plaquemines Parish, Louisiana.

The final EIS assesses the potential environmental effects of the construction and operation of the Project in accordance with the requirements of the National Environmental Policy Act. The final EIS is not a decision document. It presents Commission staff's independent analysis of the environmental issues for the Commission to consider when addressing the merits of all issues in this proceeding.

The final EIS responds to comments that were received on the Commission's August 24, 2020 Environmental Assessment (EA) and July 16, 2021 draft EIS and discloses downstream greenhouse gas emissions for the Project. With the exception of climate change impacts, FERC staff concludes that approval of the proposed Project, with the mitigation measures recommended in this final EIS, would not result in significant environmental impacts. FERC staff continues to be unable to determine significance with regards to climate change impacts.

The final EIS incorporates the above referenced EA, which addressed the potential environmental effects of the construction and operation of the following Project facilities, by the respective applicants:

Tennessee

• About 9 miles of 36-inch-diameter looping pipeline in St. Bernard Parish, Louisiana (Yscloskey Toca Lateral Loop);

• about 4 miles of 36-inch-diameter looping pipeline in Plaquemines Parish, Louisiana (Grand Bayou Loop); and
• a new 23,470 horsepower (hp) compressor station consisting of one natural gas-fired Solar Turbines Titan 130 turbine driven compressor unit along Tennessee's existing 500 line in St. Bernard Parish, Louisiana (Compressor Station 529).

SNG

• A new 22,220 hp compressor station consisting of two natural gas-fired Solar Taurus 70 turbines (11,110 hp each) in Clarke County, Mississippi (Rose Hill Compressor Station); and

• three new meter stations: Rose Hill Receipt Meter Station in Clarke County, Mississippi; Midcontinent Express Pipeline Receipt Meter Station in Smith County, Mississippi; and Toca Delivery Meter Station in St. Bernard Parish, Louisiana.

The Commission mailed a copy of the Notice of Availability of the Final Environmental Impact Statement for the Evangeline Pass Expansion Project to federal, state, and local government representatives and agencies; elected officials; environmental and public interest groups; Native American tribes; potentially affected landowners and other interested individuals and groups; and newspapers and libraries in the Project area. The final EIS is only available in electronic format. It may be viewed and downloaded from the FERC's website ( www.ferc.gov ), on the natural gas environmental documents page ( https://www.ferc.gov/industries-data/natural-gas/environment/environmental-documents ).
