On November 10, 2026, the Trump administration put out a plan to weaken the rule that protects miners from silica dust, the dust behind the rise in black lung disease.
The plan comes from the Mine Safety and Health Administration, the part of the Labor Department that keeps miners safe. It would let mining companies decide for themselves how often to test the air their workers breathe. It would also make it harder to fine them when the dust gets too thick.
Miners' advocates are furious. Vonda Robinson, president of the National Black Lung Association, called it "an earlier death sentence" for miners.
Why this dust matters
Black lung is a disease you get from breathing mine dust. It scars the lungs, and it doesn't heal. Silica dust, which comes from cutting through rock, is especially dangerous. Health researchers point to it as the leading cause of the rising black lung rates in central Appalachian coal mines, according to Louisville Public Media's reporting.
How bad is it? We reported in August that black lung in central Appalachia has hit a near-50-year high. A third of the region's miners who have worked 25 or more years underground now have it.
In 2024, after decades of pleading from federal health researchers and miners' groups, the government finalized a tougher silica rule. It cut the legal limit for silica dust. It covered not just coal mines but sand and gravel quarries too. And it required health exams for new miners, so a miner who got sick later could prove the job did it.
That rule never fully took effect. Mining industry groups sued, and between a judge's order and a pause in enforcement, the stronger protections were put on hold. As we reported, the Trump administration declined to defend the rule in court. Now it's proposing to rewrite it.
What the new plan would change
Here is what the proposal does, according to the rule and Louisville Public Media's reporting:
- No more required testing every three months. Today, mines have to test for silica dust each quarter. The plan would let them test "as frequently as necessary," in their own judgment.
- Some miners might never be tested. The rule itself says mine operators "might determine that some miners are not reasonably likely to be exposed" to silica dust "and would therefore not conduct sampling for those miners."
- Testing only where the company expects trouble. Mines could test only the areas the company believes are at or above a warning level. There is no safe level of silica dust.
- No fines based on a company's own tests. Under the 2024 rule, a company could be fined if its own dust samples showed levels over the legal limit. Under the new plan, only government inspections would count.
- A cushion before any fine. Even then, a fine would only come if a test came in 21% over the limit, to allow for measuring errors. That means miners could breathe dust up to 60 micrograms per cubic meter of air, against a legal limit of 50, with no penalty.
- No required starting health exams for many new miners. The plan makes starting exams voluntary, instead of required, for miners outside the coal industry. Those exams are often what a sick miner uses to prove they got black lung on the job and qualify for federal health benefits.
- Some mines could be left out entirely. MSHA is asking the public whether mines that dig the clays used for things like kitty litter should be exempt from the silica rules altogether.
The legal dust limit itself would stay the same. But a limit that's tested less, enforced less and fined less is a weaker limit.
Who saves money
The government says the plan would save mine companies $28.7 million a year on testing and medical exams. More than 90% of those savings would go to mining outside coal, such as quarries.
The Labor Department calls the changes "practical, commonsense, risk-based improvements" that would "better protect the nation's miners." The industry seems pleased. The National Mining Association said the plan "appears to address many of the concerns that we have raised."
The miners' side sees it differently. "The administration said they wanted to bring back coal," Brendan Muckian-Bates of the Appalachian Citizens' Law Center said. "Instead, under their watch, they are bringing back black lung."
It isn't the first hit to miners
This plan lands after other blows to the people who keep miners safe. Last year, DOGE fired almost everyone at the federal office in West Virginia that screens coal miners for black lung, until a miner with the disease and a federal judge forced it back.
And some Republicans have fought the silica rule from the start. Virginia Foxx, who chaired the House committee over the Labor Department, called it "wrongheaded recklessness" while she owned stock in a coal company.
You can weigh in
The public can comment on the plan for 60 days once it's published. MSHA will also hold a virtual public hearing on December 15, 2026.
What the record shows
With black lung at its worst level in about 50 years, the Trump administration proposed on November 10, 2026, to end required quarterly silica dust testing, let mines skip testing some miners entirely, stop fining companies over their own dust samples, and drop required starting health exams for many new miners. The government says the change saves mine companies $28.7 million a year. The head of the National Black Lung Association called it "an earlier death sentence."
