October 2012, Vol. 239 No. 10

Dominion Transmission has placed its Appalachian Gateway Project into service on time and within budget. The project will allow the transport of 484,260 Dth/d in firm transportation of natural gas produced in West Virginia and southwest Pennsylvania to storage fields and pipelines in Pennsylvania.

For the Appalachian Gateway Project, Dominion constructed four new natural gas compressor stations and upgraded two existing compressor stations, adding about 17,800 horsepower to the Dominion system. About 110 miles of new pipeline were constructed, beginning in West Virginia and terminating at Dominion’s and Spectra’s jointly owned Oakford facility in Delmont, PA, east of Pittsburgh.

The Gathering Enhancement Project included a host of upgrades in Dominion’s gathering pipelines and compressor stations, 50 MMcf/d of new natural gas processing at two new plants and expansion of Dominion’s Hastings Extraction Plant in Pine Grove, WV.
