Overthurst

Questar Overthurst Pipeline has filed an application with the Federal Energy Regulatory Commission to build a 43.3-mile loop along its system. The proposed loop pipeline would generally run parallel to the existing Overthrust Pipeline from the Rock Springs Compressor Station in Sweetwater County, WY, to a tie-in facility called Cabin 31, located within Uinta County, WY. The project would provide up to approximately 800,000 Dth/d of natural gas from receipt points on the east end of the Overthrust system to delivery points on the west end of its system. Overthrust said it has negotiated three firm transportation service agreements with Wyoming Interstate Co. Ltd. for up to 548,457 Dth/d of incremental capacity created by the project. The estimated cost of the proposed loop expansion is $94.3 million.
