The coal processing group continued an “exemplary performance” without a lost work day, said Senior Vice President of Coal Operations Joseph E. Micheletti. “We are proud of the entire Kemmerer workforce and their commitment to safety.”

The Kemmerer mine is a 13,400-acre truck and shovel complex supplying coal to the Naughton Power Station by conveyor and industrial customers by rail or truck. Staffed by 300 workers, its annual average output is 4.8 million tons.
