Staff of the Federal Energy Regulatory Commission will prepare an environmental assessment (EA) for Gulf South Pipeline Co.'s proposed St. Charles Parish Expansion Project in Louisiana, according to documents filed at the Commission Wednesday [CP16-478]. Gulf South has proposed construction of a new 5,000 hp compressor station near Montz, LA, about 900 feet of new 16-inch diameter pipeline connecting the new compressor station to Gulf South's existing Index 270-94 Lateral in St. Charles Parish, and auxiliary facilities. The completed project would provide 133,333 Dth/d to serve Entergy Louisiana LLC's proposed natural gas-fired power plant facility near Montz. Assuming regulatory approvals, Gulf South plans to begin construction in the Fall of 2017 and place the facilities in service by Sept. 1, 2018. The Commission will accept comments on the project through Sept. 23.
