The US Federal Energy Regulatory Commission (FERC) has issued a favorable environmental assessment (EA) for Dominion Carolina Gas Transmission’s (DCGT) Transco to Charleston Project. DCGT filed its initial application in March 2016, hoping to commence construction of the project facilities on or before February 1, 2017.
DCGT plans to construct, install, own, operate, and maintain new pipeline and compressor station facilities in South Carolina, USA. The plans include:
- Moore Compressor Station: Two 1400-hp (1044-kW) centrifugal turbine-driven compressor units and additional gas cooling units at its existing Moore Compressor Station located in Spartanburg County.
- Dorchester Compressor Station: New, natural gas-fired compressor station with three 1200-hp (895 kW) centrifugal turbine-driven compressor units, located in Dorchester County.
- Southern Compressor Station: Convert one existing 1200-hp centrifugal turbine-driven compressor unit from standby to utilize the unit for service at the existing natural gas-fired Southern Compressor Station located in Aiken, South Carolina.
Other Aboveground Facilities
- Metering and Regulating (M&R) Stations: New M&R and new regulating station on the Moore to Chappells Pipeline in Moore and Chappells, South Carolina, and new measurement station on the Dillon Pipeline in Dillon County.
- Mainline Valve (MLV) Sites: Eleven MLVs on the Moore to Chappells Pipeline, one MLV on the Line N pipeline at the Chappells Tie-in, and one MLV at the beginning of the Dillon Pipeline at the Reedy Creek Take-off.
- Over-pressure Protection (OPP) Systems: An OPP system, controls, and upgrades at the Charleston Town Border Station located in Charleston County and at the Greenwood Town Border Station in Greenwood County.
- Moore to Chappells Pipeline: Approximately 55 miles (89 km) of 12-in. (30.48-cm) diameter natural gas transmission pipeline in Spartanburg, Laurens, Newberry, and Greenwood Counties.
- Dillon Pipeline: Approximately 5 miles (8 km) of 4-in. (10.16-cm) diameter natural gas transmission pipeline in Dillon County.
The project will allow DCGT to provide firm transportation service of 80,000 dekatherms per day meet increasing demand for natural gas for local commercial, industrial, and power generation customers.
