The Bureau of Land Management is responsible for coal on federal lands. That coal makes up about 40 percent of total coal production in the U.S. Of the 314 existing federal coal leases, nearly a quarter of the leases are in Wyoming’s Powder River Basin. Companies acquire these leases by bidding on the right to mine the federal coal. It has generated a lot of income, which the federal government splits with states. But not everyone thinks the program is working as it should and that the government might be losing out on money.
