Questar Pipeline Company Recent Successes
Projects Recently Constructed
Questar Pipeline Main Line 104 Extension Project — Questar Pipeline Company (QPC) completed the construction of its Main Line 104 (ML 104) project and it was placed into service on November 11, 2011. This project consisted of extending ML 104, a 24–inch diameter pipeline, approximately 24.6 miles east from the Green River Block valve to the Fidlar Compressor station. The extension of ML 104 gives Questar shippers access to additional supplies on its Southern System, particularly supplies which have been aggregated to the Fidlar area processing plants from points west on the QPC Southern System.
Questar Overthrust Loop Project — Questar Overthrust Pipeline Company (QOPC) has completed the construction of its Loop project. This project consisted of adding 43 miles of 36– inch diameter pipe extending west from its Rock Springs Compressor Station to Cabin 31, a point just south of the Black’s Fork Processing Plant. The new loop interconnects with a previous Overthrust extension to Opal. At a new delivery point near Opal called Topaz Ridge, Overthrust will deliver gas onto El Paso Corp.’s Ruby Pipeline currently under construction between Wyoming and the California/Oregon border. This project increases firm transportation capacity by up to 800 Mdth/d for deliveries to the west and by 50 Mdth/d for deliveries to the east.
