CDC Estimates That 1/5 Appalachian Coal Miners Have Black Lung, So Trump Admin Delaying Dust Rule For 4th Time

Implementation of a previously approved federal rule meant to help prevent black lung in the nation’s coal miners has been delayed indefinitely, according to an update posted this week in the Federal Register. According to the update, the Mine Safety and Health Administration will wait to implement most of the rule until a federal court case related to it plays out. It’s at least the fourth time implementation of the rule has been delayed, and this time there is no set date in sight for when the changes — which included cutting permissible limits for silica dust exposure in half for coal miners — could go into effect.

The rule was first finalized under the U.S. Department of Labor and MSHA in 2024. It was meant to go into effect last April, but was pushed back to August 2025. That month, it was pushed again to October. And in October, it was delayed yet again. The lack of implementation stems from a lawsuit led by the National Sand, Stone and Gravel Association against the Labor Department requesting that the federal government block the implementation of the rule completely. None of the statutes affecting the NSSGA were slated to go into effect until 2027, per the rule.

Silica dust is a leading cause of black lung disease in coal miners. As the rule gets pushed further and further back, advocates say the lost time will have real consequences for coal miners who are suffering from symptoms of the incurable disease at younger ages than ever before. “This ruling is a green light for mining companies to continue exposing our brothers and sisters to toxic levels of silica dust that we know, with scientific certainty, causes incurable black lung and silicosis,” a representative for the United Mine Workers of America said in a statement. “Silica dust doesn’t wait for a court calendar. While lawyers argue over ‘conforming amendments’ and ‘ministerial actions,’ the lungs of miners are being scarred in real-time. A 35-year-old miner with Stage 1 silicosis doesn’t have the luxury of time.”

EDIT

The Centers for Disease Control and Prevention estimates that about 20% of coal miners in Central Appalachia are suffering from black lung — the highest rate detected in more than 25 years. One in 20 of the region’s coal miners are living with the most severe form of the condition. And in West Virginia — where coal mining seams are now thinner due to decades of mining activities — miners are being diagnosed earlier in their careers due to how much more silica-rich sandstone they have to cut through to reach the coal that remains. There is no cure for black lung. The only way to stop the disease from advancing to its most serious forms is by limiting exposure to silica dust as much as possible.
