Project Details

  • Operator: Dominion Transmission[1]
  • Parent Company: Dominion Resources[2]
  • Capacity: 484.26 million cubic feet per day[1]
  • Length: 110 miles / 177 km[1]
  • Diameter: 20-inches, 24-inches, 36-inches[1]
  • Cost: US$635 million[1]
  • Status: Operating[1]
  • Start Year: 2012[1]


The project was approved by the Federal Energy Regulatory Commission on June 16, 2011. The reported cost was approximately US$600 million.[2]

Following two years of construction, Dominion Transmission, the natural gas transportation subsidiary of Dominion Resources, placed the project into service in September 2012. The project transports natural gas produced in West Virginia and southwest Pennsylvania to storage fields and pipelines in Pennsylvania, destined for sale to customers in the Northeast and Mid-Atlantic.[2]

For the Appalachian Gateway Project, Dominion constructed four new natural gas compressor stations and upgraded two existing compressor stations. Approximately 110 mi. (177 km) of new pipeline was constructed, beginning in West Virginia and terminating at Dominion’s and Spectra’s jointly owned Oakford facility in Delmont, Pa., east of Pittsburgh.[2]

The project was developed to transport natural gas produced in West Virginia and southwest Pennsylvania to Northeast and Mid-Atlantic markets.[3]
