MORGANTOWN, W.Va. (AP) -- Top federal labor and mine safety officials are heading to West Virginia to release a long-awaited final rule on coal dust.
The announcement will be made Wednesday in Morgantown. Among those attending will be U.S. Secretary of Labor Thomas E. Perez and Joseph A. Main, assistant secretary of labor for mine safety and health. The director of the National Institute for Occupational Safety and Health, John Howard, will also discuss the new rule.
For 3 1/2 years, the Obama administration has been working on the rule to reduce miners' exposure to dust that causes black lung.
Black lung, or coal workers' pneumoconiosis, is an irreversible and potentially deadly disease caused by exposure to coal dust.
