Safety Standards for Underground Coal Mine Ventilation

MSHA published safety standards for the ventilation of underground coal mines on March 11, 1996, which became effective on June 10, 1996. The National Mining Association (NMA) and the United Mine Workers of America (UMWA) challenged the rule. On June 17, 1997, the United States Court of Appeals for the District of Columbia Circuit (D.C. Circuit) issued an order granting the petition for review relating to the 8-hour interval requirement for preshift examinations pursuant to 30 CFR 75.360(a)(1) (1996). The Court further denied the petition for review on all other issues and upheld the Agency's rulemaking. This document provides notice of, and effectuates, the Court's order.
