Powder River Basin: Arch had sales volume of 132.4 million tons of coal in 2010  in the southern Powder River Basin in Wyoming, the nation’s largest coal-supply region. This tonnage is produced at Thunder Basin’s Black Thunder and Coal Creek Mines. Arch controls approximately 1.9 billion tons of reserves in the PRB.

Western Bituminous Region: In 2010, Arch sold 16.3 million tons of almost exclusively compliance coal from its operations in this region, which includes Colorado, Utah, and southern Wyoming. The company’s Western Bituminous operations include four large underground mines and one surface mine with a total of 455 million tons of proven and probable reserves.
