Peabody Midwest Mining, LLC v. Secretary of Labor, No. 22-1242 (D.C. Cir. 2023)
Annotate this Case
Methane is considered the most dangerous gas in underground mining; in sufficient concentrations, methane can ignite and cause a potentially catastrophic explosion. To protect worker safety, Mine Safety and Health Administration (MSHA) regulations thus require miners to deenergize equipment and cease work when they detect certain methane concentrations. But during the methane inundation at the Francisco mine the miners did not stop work. They instead continued operating an energized drill, trying to stop the flow of methane. MSHA issued two orders citing the mine operator, Peabody Midwest Mining, LLC, for violating the applicable safety regulations and designated those violations as unwarrantable failures. It also individually cited the mine’s manager as Peabody’s agent. An administrative law judge and then the Federal Mine Safety and Health Review Commission agreed with MSHA that Peabody violated MSHA safety regulations, that those violations constituted unwarrantable failures, that mine manager was individually liable, and that civil penalties were appropriate. Peabody and the manager petitioned for review in this court.
The DC Circuit denied the petition. The court explained that MSHA safety regulations unambiguously prohibited Peabody’s operation of an energized drill in a high-methane environment, and substantial evidence supports the Commission’s unwarrantable failure and individual liability determinations. Further, as the Commission recognized, by permitting miners to work with energized equipment, the manager risked incurring the very hazard section 75.323(c)(2) is intended to address, i.e., potential ignition [in a] high-methane environment.
