The staff of the Federal Energy Regulatory Commission will prepare an environmental assessment (EA) that will discuss the environmental impacts of the Transco to Charleston Project, involving construction and operation of facilities by Dominion Carolina Gas Transmission LLC in Aiken, Charleston, Dillon, Dorchester, Greenwood, Laurens, Newberry, and Spartanburg counties, South Carolina.
The commission said in an Oct. 30 notice that it will use this EA in its decision-making process to determine whether the project is in the public convenience and necessity. Comments on what should be covered on the EA are due by Nov. 30.
The planned project would provide 80,000 dekatherms of natural gas per day of firm transportation service that has been fully subscribed by three customers. The Transco to Charleston Project would consist of:
- approximately 55 miles of 12-inch-diameter pipeline in Spartanburg, Laurens, Newberry, and Greenwood counties (Moore to Chappells pipeline);
- approximately 5 miles of 4-inch-diameter pipeline in Dillon County (Dillon pipeline);
- installation of two new 1,400-horsepower (hp) compressor units at the existing Moore Compressor Station in Spartanburg County;
- construction of a new 3,150-hp compressor station (Dorchester Compressor Station) in Dorchester County;
- conversion of an existing 1,050-hp compressor unit from standby to base load at the existing Southern Compressor Station in Aiken County;
- upgrades to the existing Charleston Town Border Station in Charleston County; and
- associated pipeline support facilities (metering and regulating stations, launcher and receiver assemblies, valves, and pipeline interconnects).
