The project known as the Sundance Trail Expansion will provide 150,000 dekatherms per day of firm transportation capacity from the Greasewood and Meeker/White River Hubs in Rio Blanco County, Colorado, to the Opal Hub area in Lincoln County, Wyoming. In addition, the project will replace and enhance Northwest’s compression facilities at the Vernal Compressor Station in Uintah County, Utah.

Northwest’s mainline is connected to the Piceance Basin at the Greasewood Hub through its Piceance Lateral and the Meeker/White River hubs through Northwest’s new Colorado Hub Connection pipeline and related facilities.

Phil Wright, president of natural gas pipeline business at Williams, said: “The Sundance Trail Project will meet the demand from producers to provide transportation capacity to move gas from one of the fastest-growing gas production fields in the Rockies to markets in the western US.

“At the Opal Hub, producers have access to six interstate pipelines, including Northwest, which provides significant supply options for transporting natural gas.”

The project will cost up to $65m and will be operational by November 2010. In February 2008, Northwest conducted an open season for the project and filed an application for a FERC certificate in May 2009.
