Questar Files to Build Second Expansion of Southern System

Questar Pipeline has filed an application at FERC to build its Southern System Expansion II that would bolster westbound deliveries of Rocky Mountain natural gas to Goshen, UT, where the pipe interconnects with the Wyoming-to-California Kern River Gas Transmission system.

The expansion project calls for Questar Pipeline, a subsidiary of Salt Lake City, UT-based Questar Corp., to build approximately 58.6 miles of 24-inch diameter pipeline and modify two existing compressor stations in Carbon, Duchesne and Uintah counties in Utah. The proposed facilities would help move Rocky Mountain gas near Colorado and the Uintah Basin in central eastern Utah westward, said Questar Pipeline spokesman Steve Chapman.

The expansion would enable Questar Pipeline to transport up to an additional 175,000 Dth/d of natural gas from various receipt points on Questar's southern interstate pipeline system to Questar's Main Line No. 104, which is interconnected with Kern River at Goshen. Questar has targeted the project, which it estimates will cost about $107.7 million to build, for operation on Nov. 1, 2007.

The pipeline said it has negotiated agreements for firm transportation service with seven shippers for the entire 175,000 Dth/d of the project's capacity, with terms varying between 10 and 11 1/2 years.

Questar Pipeline completed the initial expansion of its southern system in November 2005. The project, which included 18 miles of new pipe extending westward from near Price, UT, to the Oak Spring Compressor Station, added 102 ,000 Dth/d of delivery capacity to Questar's southern system.
