MSHA extends comment period for coal dust rule

Arlington, VA – After receiving an “overwhelming” response to its proposed rule (.pdf file) on lowering coal mine dust exposure, the Mine Safety and Health Administration announced it has extended the comment period from May 2 to May 31.

The proposed rule would lower the coal mine dust exposure limit, provide for full-shift sampling, add recertification and decertification criteria for people who take samples, and establish sampling requirements for continuous personal dust monitors and medical surveillance.
