BLM Rawlins Issues Endurance/Barricade Gas Infrastructure Project Decision

The Bureau of Land Management (BLM) Rawlins Field Office issues the environmental assessment (EA), finding of no significant impact (FONSI), and decision record (DR) authorizing Samson Resources Co. and Mountain Gas Resources, LLC to construct new access roads, two pipelines, two compressor stations, and install a high and low pressure loop pipeline in the Desolation Flats Natural Gas Field.  

The Endurance/Barricade Gas Infrastructure Project encompasses approximately 42,240 acres of primarily public land with a small amount of state owned land, roughly 25 miles southwest of Wamsutter, Wyo. in Sweetwater County. The project includes constructing a more direct access road to the Endurance and Barricade Units from the Wamsutter production area which proponents claim would reduce travel by approximately 120 miles each direction resulting in greater fuel efficiency, decreased dust emission, and provide a route not threatened by flooding from nearby Sand Creek. In an effort to reduce surface disturbance, the two new pipelines (one 16-inch and one 20-inch) would be co-located along the new access road. Total surface disturbance is anticipated to be approximately 495 acres with the life of the project estimated to be 30 years.  

The DR modifies the original proposal by authorizing a 14-foot access road, rather than a 20-foot roadway to minimize soil disturbance. Also, since the project is located in an area difficult to reclaim, additional mitigation measures will be required. The EA provides site-specific evaluation tiered to and incorporating analysis from the Desolation Flats Project Area Final Environmental Impact Statement and Record of Decision. The EA was made available for public comment in Aug.-Sept. 2013; comments were received from six entities, and all comments concerning potential impacts were addressed in the EA. The DR is subject to administrative review through the appeal process, which is outlined in the Decision Record.

The BLM manages more than 245 million acres of public land, the most of any Federal agency. This land, known as the National System of Public Lands, is primarily located in 12 Western states, including Alaska. The BLM also administers 700 million acres of sub-surface mineral estate throughout the nation. The BLM's mission is to sustain the health, diversity, and productivity of America’s public lands for the use and enjoyment of present and future generations. In Fiscal Year 2015, the BLM generated $4.1 billion in receipts from activities occurring on public lands.
