FERC has authorized construction and operation of Gulf South Pipeline Co.’s proposed Index 99 Expansion project, which would increase natural gas firm transportation to markets along the Gulf Coast.

The project would provide 500 MMcf/d of natural gas firm transportation service to markets along the Gulf Coast and provide an additional 250 MMcf/d of capacity to existing facilities in northern Louisiana [CP19-125]. 

The Federal Energy Regulatory Commission vote comes a year after Gulf South applied for a certificate of public convenience and necessity. FERC staff performed an environmental review for the project last summer.

All of the project’s components would be in Texas and Louisiana, which are to include installing about 22 miles of 30-inch diameter pipeline (Index 99L) in San Augustine and Sabine counties in Texas, installing a pig receiver at the intersection of the new Index 99L pipeline and Gulf South’s existing Index 99 system in San Augustine County, as well as installing 250 feet of 24-inch diameter station pipe and a 24-inch diameter pressure control valve at the Hall Summit compressor station in Bienville Parish, LA.
