SnapshotIn February 2023, a Montana federal district court judge halted the mining of federal coal at the Bull Mountains Mine No.1. This halt is pending a thorough analysis of the mine’s impacts on ranchers, vital water sources, and the surrounding environment. The decision will require the Office of Surface Mining (OSM) to prepare an Environmental Impact Statement (EIS) to determine whether the expansion meets legal requirements to proceed.
