Alpha Coal West, Inc. (Alpha) submitted a proposal to the Wyoming Department of Transportation (WYDOT) to relocate approximately 4.35 miles of Wyoming Highway 59 (WYO 59) to allow mining operations in the vicinity of Eagle Butte Mine to continue (Figure 1). The project is known as the WYO 59 relocation project. Alpha is financially responsible for the cost associated with evaluating, designing, and constructing the relocated road. WYDOT is responsible for approving the location of the relocated road segment and overseeing design and construction. No federal or state of Wyoming (State) funds will be used to relocate the highway. To support the decision-making process associated with potentially relocating WYO 59, WYDOT completed an environmental review and engineering feasibility study of the proposed road relocation. The study included obtaining input from affected stakeholders and the residents of Campbell County. The results of the environmental review and associated stakeholder outreach are documented in this Environmental Overview Report and Feasibility Study. 2.0 Why is WYDOT Considering Relocating WYO 59? Alpha owns and operates the Eagle Butte Mine in Campbell County. The mining operations are currently restricted by the current location of WYO 59. To continue mining operations, as permitted by the State and the Bureau of Land Management (BLM), Alpha has requested WYDOT evaluate relocating a 4.35-mile segment of WYO 59. WYDOT responded to Alpha’s request to conduct the evaluation; the results are documented in this Environmental Overview Report and Feasibility Study. 3.0 What Decision is WYDOT Making? WYDOT is considering whether or not to relocate WYO 59. WYO 59 would be relocated from its current location south and east of Eagle Butte Mine to north of the Mine. Most of the current WYO 59 alignment would be abandoned and the land converted to mine operations. A small
