Government eyes more coal regulations as black lung cases sharply rise among miners
Some U.S. industries where silica exposure occurs, like construction and fracking, are regulated by OSHA, the Occupational Safety and Health Administration.
That agency recognizes the threat and mandates exposure limits and safety precautions. But coal mining is covered by a different agency and has been an exception. That’s now changing. In June, the federal Mine Safety and Health Association, or MSHA, proposed a rule to cut the exposure limit for silica dust in half for a work shift.
