The staff of the Federal Energy Regulatory Commission will prepare an environmental assessment (EA) on the Gulf Trace Expansion Project involving construction and operation of facilities by Transcontinental Gas Pipe Line Co. LLC (Transco) in Cameron, Calcasieu, Beauregard, Evangeline, and East Feliciana parishes, Louisiana.
The commission said in a Feb. 4 notice that it will use this EA in its decision-making process to determine whether the project is in the public convenience and necessity. The scoping period where FERC will take input on what should be covered by the EA will close on March 6.
The Gulf Trace Expansion Project would provide about 1.2 million standard cubic feet of natural gas per day from its Station 65 Zone 3 Pool in St. Helena Parish, Louisiana, southward along its existing mainline, existing Southwest Louisiana Lateral, and the proposed project facilities to the Sabine Pass Liquefaction LLC liquefied natural gas terminal (SPLNG Terminal) in Cameron Parish, Louisiana. The pipeline would extend from a tie-in with the existing NHI Laterals C and D to SPLNG Terminal.
The Gulf Trace Expansion Project would consist of:
- about 6.97 miles of 36-inch-diameter pipeline (the Gulf Trace Lateral) in Cameron Parish;
- addition of two 16,000 horsepower (hp) gas turbine-driven compressor units at Transco’s existing Compressor Station 44 in Cameron Parish;
- two 16,000 hp gas turbine-driven compressor units at the new Compressor Station 42 at the junction of the Transco’s mainline and its Southwest Louisiana Lateral in Calcasieu Parish;
- piping and valve modifications on Transco’s mainline at existing Compressor Stations 45, 50, and 60 in Beauregard, Evangeline, and East Feliciana parishes to allow for bi-directional flow;
- two new meter stations, one adjacent to the SPLNG Terminal in Cameron Parish (SPLNG Meter Station) and one adjacent to the Texas Gas Interconnection in Evangeline Parish (Duralde Meter Station);
- piping and valve modifications, and pig launcher and receivers required to tie-in the Gulf Trace Lateral with the existing NHI Laterals C and D at the milepost 6.8 valve site in Cameron Parish; and
- appurtenant underground and aboveground facilities.
