Project Details

To meet market demand for natural gas, Questar wanted to provide an additional 170,000 dekatherms of natural gas per day via new pipeline capacity plus increased compression at existing compressor sites in central Utah. Barnard Pipeline's role in this fast-track project involved constructing 59 miles of 24-inch natural gas pipeline through solid rock at high elevations. The project entailed two road and railroad bores; blasting; drilling and shooting; 15 creek crossings; 200 acres of clearing; and 2 miles of 12-inch waterline for testing. The remote right-of-way (ROW) through Utah's Book Cliffs Range proved challenging; the limited access required establishing two warehouse/office setups at the project's north and south ends. Travel to the middle of the job took two hours over rough terrain.

In 2008, Questar received an Earth Day Award from the Utah Board of Oil, Gas and Mining for constructing this project in a sensitive manner that resulted in a “pipeline right-of-way that was virtually unnoticeable to users of the road immediately after construction.” Some of this construction took place in archaelogically sensitive areas.
