New Study: Black Lung Disease Rate in Appalachia Is the Worst in Nearly 50 Years as Coal Miner Protections Stall | FRONTLINE | PBS | Official Site

A new report has found that black lung disease is now striking coal miners in Appalachia at rates not seen in nearly half a century, even as federal protections for miners remain stalled. The study, released this week, shows the disease is as prevalent today as it was in the early 1970s, before modern dust control rules were fully enforced.

Researchers looked at data from clinics across Virginia, West Virginia, and Kentucky. They found that the most severe form of the disease, called progressive massive fibrosis, is showing up in younger miners and in those who have worked fewer years underground. That is a shift from past patterns, where the disease typically appeared after decades of work.

The numbers are stark. Among miners with at least 25 years of experience, nearly one in five now shows signs of the disease. That is roughly the same rate recorded in the early 1970s, when the federal government first began tracking the illness. For comparison, the rate had dropped to around 5 percent in the late 1990s, after dust limits were tightened.

But those limits have not been updated since then. The study's authors point to a rule proposed under the Obama administration that would have reduced allowable dust exposure further and required better monitoring. That rule was finalized in 2014, but implementation has been slow, and industry groups have fought parts of it in court. Miners' advocates say the current regulatory environment leaves workers unprotected.

The disease is entirely preventable, but it is also incurable. It causes scarring in the lungs, leading to shortness of breath, coughing, and eventually heart failure. Thousands of miners have already died from it, and many more are expected to in the coming years. The study's authors are calling for immediate action, including stricter enforcement of existing rules and a new push to lower dust limits further. Without that, they warn, the region will keep losing miners to a disease that should have been eliminated long ago.
