About this record
These figures come from public Mine Safety and Health Administration (MSHA) open government data on mines, inspections, violations and assessed violations. MineCitation copies them as published and does not add findings of its own.
A citation records a condition an MSHA inspector found. Operators can contest citations and penalties, and amounts can change after review. MineCitation is not legal advice.
