Apex Expansion

The Apex Expansion Project increased the amount of natural gas transported on the Kern River system by approximately 266 million cubic feet per day.  

The project included the installation of approximately 28 miles of new 36-inch-diameter pipeline through the Wasatch Mountains in Morgan, Davis and Salt Lake counties of northern Utah; the addition of 78,000 incremental horsepower of compression at one new and three existing compressor stations; and replacement of a compressor unit at one existing station. Kern River made every effort to minimize construction impacts on the environment and landowners along the rights of way, and worked closely with local municipalities and state agencies to ensure the project reflected the communities’ interests and needs.
