(Reuters) – A divided federal appeals court on Monday revived a challenge by the Sierra Club and other environmental groups to Signal Peak Energy’s expansion of its Bull Mountains Mine in Montana, but allowed the project to continue for now.
The 9th U.S. Circuit Court of Appeals said the U.S. Interior Department had offered “no convincing rationale” for its 2018 finding that the expansion’s effect on climate-warming greenhouse gas (GHG) emissions would be insignificant, even though burning its coal would “generate more GHG emissions annually than the largest single point source of GHG emissions in the United States.”
