Description

The Department of the Interior approved a mining plan modification for the Bull Mountains coal mine in Montana, allowing Signal Peak Energy LLC to mine approximately 22.8 million tons of federal coal and 34.5 million tons of adjacent non-federal coal. The project involves the expansion of coal mining operations in Musselshell and Yellowstone counties, with coal exports to Japan and South Korea. The approval was granted using emergency permitting procedures that shorten the environmental review process to 28 days, bypassing the usual multi-year review and public comment period.
