Coal-Supply Regions

As the second largest producer of coal in the United States, we utilize state of the art equipment and mining techniques. This maximizes our efficiency in our mining operations in the three main low-sulfur, coal-producing regions:

Central Appalachia
Our operations in Central Appalachia are located in southern West Virginia, eastern Kentucky, and Virginia.  During 2007, these mining complexes sold approximately 13.9 million tons of compliance, low-sulfur and metallurgical coal. We control approximately 338 million tons of proven and probable reserves in CAPP.

Powder River Basin
Arch had sales volume of 99 million tons of coal in 2007 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 1.75 billion tons of reserves in the PRB.

Western Bituminous Region
in 2007, Arch sold more than 19 million tons of 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 460 million tons of proven and probable reserves.
