The Powder River Basin (PRB), located in the western United States, is a coal mining region that has evolved throughout the half century since the first largescale mine began in the 1970s, as shown in Fig. related to commodity pricing, high inflationary periods and, more recently, low demand, associated with power producers switching from coal to natural gas or renewable energy ...
The Powder River Structural Basin covers an area of more than 61,000 km 2 in northern Wyoming and southern Montana (Fig. 1). The Basin is an important source of energy resources, containing the largest coal resources of any coal field in the contiguous United States (Glass, 1997) and substantial oil and natural gas resources.
Cretaceous The thickest section of the Powder River Basin is composed of Cretaceous rocks, an overall regressive sequence of mostly marine shales and sandstones deposited in the Western Interior Seaway Tertiary The coal beds of the region began to form about 60 million years ago when the land began rising from a shallow sea.

Subbituminous coal is the predominant rank of coal produced west of the Mississippi River, accounting for 62 percent of the region's total coal output in 1992. Subbituminous coal in Wyoming's Powder River Basin, the principal source of this rank of coal, has an emission factor of pounds of carbon dioxide per million Btu.
