Colorado Attorney General Phil Weiser and a coalition of six environmental groups on Wednesday challenged the U.S. Department of Energy to reconsider its emergency order that would keep open a broken coal-fired power plant in Craig. Weiser called the emergency order, signed by Energy Secretary Chris Wright on Dec. 30, government overreach, saying there is no evidence of an energy emergency that would require keeping the plant open. The environmental groups said they are prepared to file a lawsuit if the department does not respond to their petition. Tri-State had expected the emergency order and had not let go of any employees ahead of the planned closure date. Environmental groups also have vowed to fight that decision.
