Reducing Mine Dust Rule Working

Chester Fike was in his 30s after doctors diagnosed him with black lung. As the disease progressed, the West Virginia coal miner was eventually so incapacitated that a simple walk with his family was impossible. In the summer of 2012, four months after a double lung transplant, Fike died at age 60.

In an effort to spare others the same fate, the Mine Safety and Health Administration (MSHA) published a final rule, which took effect in August, to lower miners’ exposure to respirable coal mine dust in all underground and surface coal mines.

The good news is during the rule’s first phase this past year, from Aug. 1 through Dec. 31, over 23,600 dust samples ended up collected, and results show 99 percent of samples are in compliance. Since MSHA launched its “End Back Lung — Act Now” campaign in 2009, the yearly average of respirable dust levels of designated mining occupations in underground coal mines has fallen every year and, in 2014, reached the lowest level ever recorded.

“These results show that the new dust rule is working, and miners should be breathing cleaner air at coal mines,” said Joseph A. Main, assistant secretary of labor for mine safety and health. “Despite concerns from some in the mining industry, most of the valid samples collected have met compliance levels. That’s good news for the health of all coal miners and our efforts to end black lung disease,” Main said.

Of the total respirable dust samples collected in the five-month period, 17,949 came from 319 underground mines; 252 of those samples (or 1.4 percent) exceeded compliance levels used to determine if it warranted a violation.

“Lowering Miners’ Exposure to Respirable Coal Mine Dust, Including Continuous Personal Dust Monitors,” became effective on Aug. 1, 2014, and 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.

Prolonged exposure to respirable coal mine dust causes lung diseases, such as coal workers’ pneumoconiosis, emphysema and progressive massive fibrosis. These diseases collectively referred to as “black lung,” can lead to permanent disability and death.

The National Institute of Occupational Safety and Health (NIOSH) estimated more than 76,000 miners have died since 1968 as the result of the disease, and more than $45 billion in federal compensation benefits paid out to coal miners disabled by black lung and those who survived them. Evidence indicates more still needs to occur as miners, including young miners, end up diagnosed with the disease.
