FILE - In this Nov. 15, 2016, file photo, a mechanized shovel loads coal from an 80-feet thick seam into a haul truck at Cloud Peak Energy's Spring Creek mine near Decker, Mont. Coal from the mine is shipped to power plants for generating electricity. The Interior Department has put on hold changes to how it values coal extracted from public lands after mining companies sued in federal court to challenge the rules. Interior officials say in a Federal Register announcement due to be published Monday, Feb. 27, 2017, that current rules will remain in place pending a court decision. The changes, crafted under the administration of President Barack Obama, were aimed at ensuring companies don't shortchange taxpayers on coal sales to Asia and other markets.
