Secretary of Labor v. KC Transport, Inc., No. 22-1071 (D.C. Cir. 2023)
Annotate this Case
MSHA’s jurisdiction, the Federal Mine Safety and Health Review Commission (“Commission”) held that for the list of items in Section 802(h)(1)(C) to be considered a “mine,” the items had to be located at an extraction site, or the roads appurtenant thereto. Because neither the trucks nor the facility associated with the citations at issue were located on land covered under subsections (A)–(B), the Commission found they failed to constitute a “mine” and vacated the citations. The Commission also found that, as an independent contractor not engaged in servicing a mine at the time of the citation, KC Transport failed to qualify as an “operator” under Section 802(d) of the Mine Act. The Secretary of Labor (“the Secretary”), acting through MSHA, appealed the Commission’s decision and asked the court to uphold the two citations as an appropriate exercise of the Secretary’s jurisdiction under the Mine Act. In the Secretary’s view, subsection (C) of the “mine” definition covers KC Transport’s facility and trucks because they were “used in” mining activity.
The DC Circuit vacated and remanded the Commission’s decision, allowing the Secretary to interpret the statute’s ambiguous language. The court explained that given the Mine Act’s language, context, and the court’s binding precedent, it finds that the Commission erred in its interpretation of the “mine” and “operator” definitions. And we generally defer to the Secretary’s reasonable interpretation of an ambiguous statute—even when the Commission disagrees. But here, the Secretary’s position treats subsection (C) as 4 unambiguous and makes no meaningful effort to address the numerous practical concerns that would arise under such an interpretation.
