Peabody Energy Corp: MSHA issues imminent danger order at NARM

What happened Peabody Energy Corp reported on Oct 16, 2026 that on Jul 9, 2026 Peabody Powder River Mining, LLC received an imminent danger order issued by the Mine Safety and Health Administration (“MSHA”) under Section 107(a) of the Federal Mine Safety and Health Act of 1977 at the North Antelope Rochelle surface mine located in Campbell County, Wyoming (“NARM”). The order was issued because the catch berm at the base of a highwall adjacent to an active haul road had filled with material and additional loose material on the highwall could overtop the berm and fall onto the roadway. NARM personnel removed miners from the affected area and took actions to alleviate the condition, and MSHA terminated the 107(a) order later that same day. No injuries resulted.
