Supreme Court Asked to Limit Mine Safety Jurisdiction for KC Transport

The Supreme Court’s New Front in the Battle Over Regulatory Reach

A West Virginia trucking company has taken a high-stakes disagreement to the U.S. Supreme Court, challenging the federal government’s authority to label an off-site vehicle repair shop as a “mine.” In a petition filed on November 5, KC Transport is asking the justices to draw a clear line between the actual extraction of minerals and the service businesses that support the broader industry, according to the West Virginia Record.

At the heart of the dispute is a March 11, 2019, visit from a Mine Safety and Health Administration (MSHA) inspector to a maintenance yard in Emmett. The inspector found two trucks undergoing repairs without proper safety blocking and a worker beneath one of the vehicles. This led to two citations and $8,251 in proposed civil penalties. For KC Transport, the issue is not merely the cost of the fine, but the fundamental question of whether federal regulators can extend their jurisdiction to a private repair facility where no coal is actually extracted, milled, or prepared.

A Long-Running Legal Tug-of-War

The company’s path to the Supreme Court has been anything but linear. Initially, an administrative law judge upheld the MSHA citations, but the Federal Mine Safety and Health Review Commission later reversed that decision, siding with the trucking firm. The Department of Labor pushed back, taking the case to the U.S. Court of Appeals for the District of Columbia Circuit. In a 2-1 ruling issued on April 17, the appeals court sided with the government, determining that the facility qualified as a mine because of its deep operational ties to nearby mining sites.

The court noted that approximately 60% of the facility’s services supported five specific mines operated by Ramaco Resources. Furthermore, the two trucks cited in the incident were not licensed for public-road use and were primarily tasked with hauling coal between those mines and a preparation plant just a mile away. The majority concluded that the facility was “necessarily connected” to the mining process, bringing it under the reach of the Federal Mine Safety and Health Act of 1977.

The Shadow of Loper Bright

This case is a bellwether for the post-Chevron era of American law. KC Transport first appealed to the Supreme Court in 2024. However, after the high court’s landmark ruling in Loper Bright Enterprises v. Raimondo—which dismantled the doctrine requiring judges to defer to agency interpretations of ambiguous laws—the justices sent this case back to the lower court to be reconsidered without that traditional deference.

Despite the change in legal landscape, the appeals court panel reached the same conclusion in April, maintaining that the facility’s connection to mining operations was sufficient to justify federal oversight. When the full appeals court declined to rehear the case in July, the company turned once more to the Supreme Court to settle the matter.

Under any fair reading of the Mine Act, a repair shop where no one extracts, mills, or prepares coal or other minerals is not a mine, and the government can’t regulate it as one.

That sentiment, expressed by Pacific Legal Foundation attorney Adi Dynar, highlights the broader anxiety among independent businesses. The company argues that if the current ruling stands, it could set a precedent exposing a wide range of third-party suppliers and repair shops to a regulatory framework never intended for them. The appeals court, however, has maintained that its decision is narrow, focusing on the specific, substantial connections between this particular yard and the mining operations it served, rather than creating a blanket rule for all industry contractors.

What Happens Next

The November 5 filing is a petition for review; it is not yet an argument session. The Supreme Court must now decide whether to grant the petition and hear the case on its merits. For now, the legal ambiguity surrounding the 1977 Mine Act remains, leaving independent businesses across the mining sector waiting to see just how far the government’s oversight truly extends.
