Who We Are

St. Louis-based Arch Coal is one of the nation’s largest and most efficient coal producers.

In total, we contribute about 12% of America’s coal supply from our 11 mining complexes in Wyoming, Utah, Colorado, West Virginia, Kentucky, and Virginia.

With more than 137 million tons of pro forma coal sales in 2008, we provided U.S. utilities with the fuel for roughly 6% of the nation’s electricity.

We control a vast domestic reserve base totaling 2.8 billion tons. Of that total, 82% is low in sulfur and 74% meets the most stringent requirements of the Clean Air Act without the application of expensive scrubbing technology.

We’re proud stewards of safety and the environment, and have amassed dozens of national and state awards of excellence.

Arch Coal is traded on the New York Stock Exchange under the ticker symbol ACI.
