In a rebuke of the U.S. Office of Surface Mining, Judge Susan Watters ruled the agency failed to disclose the full impacts of expanding southeastern Montana’s Spring Creek mine, the largest in the state. Watters said the agency ignored federal law by failing to address the impacts of trains hauling coal from the mine, the air pollution consequences of burning more coal from the mine, and the climate costs of greenhouse gas emissions that would result from more coal mining and burning. Her ruling was the latest in a series of court rulings that have rejected federal fossil fuel programs.
