Questar Pipeline Company (Questar) is a natural gas pipeline transportation company that operates more than 2,400 miles of transmission and gathering pipelines in northwestern Colorado, southwestern Wyoming, and northern and central Utah and who, through its interconnections with other major pipeline, provides customers with gas gathering, transportation, and storage services. Questar has applied to the Bureau of Land Management (BLM), Rock Springs District, for approval to construct the Birch Creek Pipeline in southwestern Sublette County, eastern Lincoln County, and northwestern Sweetwater County, Wyoming (Figure 1.1). The proposed pipeline would be a gathering line for existing and future natural gas fields in the area, and would extend from the end point of Questar's existing Jurisdictional Lateral No. 35 in Sweetwater County north to the Saddle Ridge area northwest of La Barge. Construction would begin September 1, 1994 and would be completed by November 1, 1994, or as soon thereafter as practicable. The proposed right-of-way (ROW) was chosen because it would be the shortest, most practical route for gathering natural gas from existing and anticipated production areas, and because it would parallel existing pipeline ROWs for much of its length to minimize environmental impacts.
