Sunrise Coal, LLC, a subsidiary of Hallador Energy Company, received an imminent danger order under Section 107(a) of the Federal Mine Safety and Health Act of 1977 (Mine Act) on March 25, 2026. The order was issued by the federal Mine Safety and Health Administration (MSHA) at Oaktown Fuels, Mine No. 1, located in Knox County, Indiana (MSHA ID# 12-02394). The alleged violation involved an electrician performing electrical work on equipment that was not de-energized. Oaktown personnel immediately de-energized the equipment following the order. No injuries resulted from the condition, and production at the mine was not interrupted. Hallador Energy Company disagrees that the condition constitutes an imminent danger under the Mine Act and intends to contest the 107(a) order.
