Feds: Most coal dust samples would meet new mark

CHARLESTON, W.Va. (AP) — Federal officials say almost every mine sample taken since August would meet tougher limits on coal dust.

A U.S. Mine Safety and Health Administration news release Monday said 99 percent of about 7,500 samples were below the new standard.

Initial requirements of the coal dust rule became effective Aug. 1. The federal rule proposed in 2010 aims to reduce black lung disease.

New requirements include increased dust sampling in mines and citations when coal operators don’t take immediate action for high levels.

In February 2016, better monitoring equipment will be required. In August 2016, the allowable concentration of coal dust will drop. Officials will be able to cite violations based on single samples, instead of average levels.

Federal officials said mines met the new standard despite voicing concerns they couldn’t.
