Secretary of Labor v. M-Class Mining, LLC, No. 20-1369 (D.C. Cir. 2021)
Annotate this Case
During repair operations in M-Class's underground mine, a miner experienced chest pains and difficulty breathing. At a hospital, a physician examined him and notified the police that a miner was suffering from CO poisoning. The police called the Mine Safety and Health Administration (MSHA) hotline. An MSHA Inspector arrived at the mine that night, issued a section 103(k) order to suspend operations in the affected area, reviewed a report based on the mine’s gas detectors and data from one miner’s personal gas spotter, entered the mine, detected no elevated CO level, and allowed mining to resume. The Inspector also started the diesel air compressor and detected no elevated CO level but modified the Order to remove the compressor from service pending an investigation. MSHA tested the compressor but ultimately found no evidence that it was the source of the miner’s illness. MSHA insisted that M-Class submit an action plan governing the compressor use's before the Order would be terminated. MSHA rejected M-Class’s submission.
M-Class filed a notice of contest. MSHA terminated the Order. The ALJ declined to dismiss the contest and concluded that the [terminated] Order was appropriate. The Commission concluded that the case was not moot but vacated the terminated Order, finding no substantial evidence that an accident occurred. The D.C. Circuit vacated the decision, finding the matter moot. MSHA terminated the challenged Order. Apart from the speculative, it no longer poses a risk of legal consequences.
