MSHA says coal dust sampling results show mines are complying with new dust rules

October 21, 2014

THE U.S. MINE Safety and Health Administration (MSHA) announced that approximately 99 percent of the 7,456 valid respirable dust samples collected during the first two months under the new respirable coal mine dust rule met compliance levels.

Between Aug. 1 and Sept. 30, MSHA collected 4,255 dust samples from 515 coal mines; 20 of those (or nearly 0.5 percent) exceeded compliance levels used to determine if a violation is warranted. Of the 3,201 samples submitted by mine operators, 42 (or 1.3 percent) exceeded compliance levels.

The rule, “Lowering Miners’ Exposure to Respirable Coal Mine Dust, Including Continuous Personal Dust Monitors,” became effective on Aug. 1. It aims to substantially increases operator sampling for respirable coal mine dust and requires an operator to take immediate corrective action when an operator’s sample shows excessive concentrations. The final rule authorizes MSHA to cite an operator based on a single MSHA sample showing excessive dust, rather than on an average of samples.

“These samples were all generated under the new, more rigid standard that requires them to be taken when mines are operating at 80 percent production or more,” said Joseph A. Main, assistant secretary of labor for mine safety and health. “And the results clearly show that mine operators are able to comply with the rule. That’s good news for the health of all coal miners and our efforts to end black lung disease.”

Since Aug. 1, MSHA has conducted comprehensive outreach, education and training on the new respirable dust rule. In addition to meeting with the mining community across the country and posting dozens of frequently asked questions on its website to help mine operators comply, MSHA coal enforcement and training personnel have trained and certified more than 1,200 individuals in respirable dust sampling and calibration.
In collaboration with the National Institute for Occupational Safety and Health, MSHA will host a series of workshops on “Best Practices for Controlling Respirable Dust in Coal Mines.”

“These workshops are part of MSHA’s ongoing commitment to assist the mining industry in the implementation of the new rule,” said Main.

The first workshop will take place on Tuesday, Oct. 28, at the National Mine Health and Safety Academy in Beaver, West Virginia. Mine managers and operational staff, mine workers, safety and health professionals, mine engineers, manufacturers and consultants are encouraged to attend. Additional workshops will be held in Birmingham, Alabama; Evansville, Indiana; and Grand Junction, Colorado, in 2015.
