Project Description

The Bureau of Land Management (BLM) Miles City Field Office intends to prepare an EIS considering a proposal from Bridger Pipeline Expansion LLC (Bridger) to develop and operate a 647-mile, 36-inch buried crude oil pipeline. The project would extend from the United States/Canadian border in Phillips County, Montana, to an existing crude oil terminal facility near Guernsey in Platte County, Wyoming. The project would include associated infrastructure, including access roads, pump stations, valve sets and pipeline markers. The project is proposed to traverse Federal, State and/or private lands in the following counties: Phillips, Valley, Daniels, Sheridan, Roosevelt, Richland, Wibaux, Fallon and Carter Counties in Montana, and Crook, Weston, Niobrara, Goshen, and Platte Counties in Wyoming.  

In Montana, the pipeline would cross 21.5 miles of BLM administered lands managed by the Malta and Glasgow Field Offices (combined under the HiLine Resource Management Plan) and 31.0 miles managed by the Miles City Field Office. In Wyoming, the pipeline would cross 6.1 miles of BLM administered lands managed by the Newcastle Field Office and 5.2 miles of the Thunder Basin National Grassland, administered by the U.S. Forest Service.

Under the MLA authority, BLM will serve as the lead for the federal agencies and the environmental analysis will be undertaken by BLM and the Montana Department of Environmental Quality (DEQ) who will be working as Joint Leads. DEQ requires completion of an EIS under the Montana Environmental Policy Act (MEPA) as part of their Major Facilities Siting Act process. The U.S. Army Corps of Engineers, U.S. Fish and Wildlife Service, and U.S. Forest Service will be acting as Cooperating Agencies on the project. Additional Federal, State, and local government entities may join the project as Cooperating Agencies, Co-leads, or in some other official capacity in the future.
