Arch Coal is an American coal mining and processing company. The company mines, processes, and markets bituminous and sub-bituminous coal with low sulfur content in the United States. Arch Coal is the second largest supplier of coal in the U.S. behind Peabody Energy. The company supplies 15% of the domestic market. Demand comes mainly from generators of electricity.
Arch Coal operates 32 active mines and controls approximately 5.5 billion tons of proven and probable coal reserves, located in Central Appalachia, the Powder River Basin, Illinois basin and the Western Bituminous regions. The company operates mines in Colorado, Kentucky, Utah, Virginia, West Virginia and Wyoming, and is headquartered in St. Louis, Missouri. The company sells a substantial amount of its coal to producers of electric power, steel producers and industrial facilities.

Arch Coal was formed in July 1997 through the merger of publicly traded Ashland Coal, Inc. and privately held Arch Mineral Corporation. Arch Mineral had its origins in 1969, when it was formed as a partnership between Ashland Oil (now Ashland Inc.) and the H.L.Hunt family of Dallas, Texas; Ashland Coal was formed in 1975 as a wholly owned subsidiary of Ashland Oil. With the completion of the merger, Arch became the leading producer of low-sulfur coal in the eastern United States.
In June 1998, Arch Coal expanded into the western United States with the acquisition of the coal assets of Atlantic Richfield. Included in this transaction were the Black Thunder Coal Mine and Coal Creek mines in the Powder River Basin of Wyoming; the West Elk longwall mine in Gunnison County, Colorado; and a 65% interest in Canyon Fuel Company, which operates three longwall mines in Utah.
In July 2004, Arch Coal solidified its position as a leading producer of high-Btu, low-sulfur western bituminous coal with the acquisition of the remaining 35% interest in Canyon Fuel Company and its 161-million-ton reserves.
In August 2004, Arch again expanded its position in the Powder River Basin with the acquisition of Triton's North Rochelle mine adjacent to Arch's existing Black Thunder operation. By integrating the North Rochelle mine with Black Thunder, Arch created the premier mine in the nation's fastest growing coal supply region.
In September 2004, Arch again added to its Powder River Basin reserves when it was the winning bidder on Little Thunder, a 719-million-ton federal reserve tract adjacent to the Black Thunder Coal Mine.
In December 2005, Arch Coal sold select eastern assets to Magnum Coal Company to unlock the value of some of its Central Appalachian holdings, sharpened its focus in that region, and strengthened its balance sheet in preparation for future growth.
In October 2009, Arch acquired Rio Tinto's Jacobs Ranch mine and blended it with Black Thunder Coal Mine in the southern Powder River Basin of Wyoming, creating the single largest coal mining complex in the world.
In November 2009, Arch acquired the rights to mine 731 million tons of Otter Creek coal reserves in the northern Powder River Basin of Montana.
In December 2011, Arch Coal became the successful bidder for a 222 million ton federal coal lease known as the South Hilight tract in the southern Powder River Basin.
Their top competitors include:
Mountaintop removal in Appalachia
Their West Virginia mining operations in the Appalachian Mountains were the subject of a critical documentary in 2002 on Now with Bill Moyers on PBS. Arch's Dal-Tex mining operations above the town of Blair, West Virginia were the subject of a 1998 U.S. News & World Report story "Shear Madness" by Penny Loeb. The story documented the impacts of mountaintop removal on communities close to the mines and their subsequent depopulation. A 1999 lawsuit brought by the West Virginia Highlands Conservancy, Bragg v. Robertson was the first successful citizen lawsuit to stop Arch's proposed mountaintop removal valley fill. The fill would have buried several miles of stream at Pigeon Roost Hollow near Blair, West Virginia.
In his ruling for the plaintiffs, Judge Charles H. Haden stated that "If there is any life form that cannot acclimate to life deep in a rubble pile, it is eliminated. No effect on related environmental values is more adverse than obliteration...Under a valley fill the water quality of the stream becomes zero. Because there is no stream, there is no water quality."
As of 2012, the company reported that surface mining in Appalachian mountains accounted for roughly 4 percent of their annual coal production.
Arch Coal’s subsidiary operations reported a water compliance rate of 99.9 percent over a 10-year period between 2002 and 2012.
In 2012, Arch Coal became the first energy company to earn the Conservation Legacy Award from the National Museum of Forest Service History. The Museum of Forest Service History awarded this honor “in recognition of [Arch Coal’s] commitment to the protection of natural resources, wildlife and water quality values during mining and restoration operations.”
