Canyon Fuel Company v. Secretary of Labor, No. 17-9541 (10th Cir. 2018)Annotate this Case
Canyon Fuel Company operated the Sufco Mine, a coal mine located in Sevier County, Utah. Under federal law, the mine had to have two escapeways in the event of an emergency: a primary and an alternate. An inspector for the Mine Safety and Health Administration (“MSHA”) cited Canyon Fuel for a violation of this mine safety requirement. Canyon Fuel unsuccessfully contested the citation before the federal agency and appealed to the Tenth Circuit Court of Appeals. After review, the Tenth Circuit affirmed the Secretary of Labor’s interpretation of the regulation as requiring consideration of both above- and below-ground factors, but vacated the citation because it was not supported by substantial evidence.
