As expected, the new MSHA rule lowers the maximum exposure to 50 micrograms per cubic meter of air during an eight-hour shift. The current limit is 100 micrograms per cubic meter.
The rule will take effect on June 17. Coal producers will have 12 months to comply. Metal and nonmetal mine operators will have 24 months.
Respirable crystalline silica is a carcinogen. It can cause lung disease, silicosis, lung cancer, progressive massive fibrosis and kidney disease. Coal dust containing silica dust has been shown to increase the severity of black lung cases and affect miners in their 30s and 40s.
The silica dust problem is thought to be caused by the mechanization of mining, especially in central Appalachia. Large machines grind through larger volumes of rock to maximize coal production.
Mine operators are supposed to ventilate mine work areas to lower the concentration of coal and rock dust, as well as methane.
Studies have shown in recent years that 1 in 5 miners in central Appalachia has black lung.
An investigation of the 2010 Upper Big Branch mine disaster in Raleigh County found that 17 of the 24 miners whose lung tissue could be sampled showed signs of black lung disease. A total of 29 miners died in the explosion, caused by a mixture of methane and coal dust.
MSHA rolled out the silica dust rule at an event Tuesday morning in Uniontown, Pennsylvania.
U.S. senators from Ohio, Pennsylvania, Virginia and West Virginia, including Sen. Joe Manchin, praised the rule, though they had previously criticized the agency for delays to its implementation.
On this West Virginia Morning, fewer coal miners are killed on the job than in years past, but black lung remains a persistent problem. A big reason for that is silica dust.

The Mine Safety and Health Administration will require mine operators to have written safety programs for mobile equipment used in surface and underground operations.
Federal mine safety regulators have announced a new rule aimed at cutting down the leading causes of fatal injuries to workers.
The Mine Safety and Health Administration will require mine operators to have written safety programs for mobile equipment used in surface and underground operations.
Machinery and powered haulage have become the leading cause of serious and fatal accidents in all types of mining.
According to MSHA statistics, 26 workers have sustained fatal injuries industry wide this year from mobile equipment. In the coal sector, six were killed this year, including two in West Virginia.
In one instance, a worker was thrown off a bulldozer. In another case, a worker was pinned by a personnel carrier that rolled backward and overturned.
Chris Williamson, the assistant secretary for Mine Safety and Health, says he’d like to see mine operators make training a priority and eliminate hazards that can put worker safety at risk.
The final rule will be published in the Federal Register on Wednesday.
A separate MSHA rule to lower miners’ exposure to silica dust is due to roll out in April. Silica dust has worsened black lung cases and caused the disease to affect younger miners.
Chris Williamson, the assistant secretary for Mine Safety and Health at the U.S. Department of Labor, says participation in the Part 90 program is up 750 percent.
The head of the federal Mine Safety and Health Administration says participation is up in a program that helps coal miners avoid exposure to silica dust.
Chris Williamson, the assistant secretary for Mine Safety and Health at the U.S. Department of Labor, says participation in the Part 90 program is up 750 percent.
Last year, MSHA said it would look for ways to encourage more miners to take part in the program, which allows those who have been diagnosed with black lung disease to continue to work in the industry but in positions where they won’t be exposed to as much silica dust.
The move can slow the progression of a disease that’s affecting miners at younger ages and more severely than it did in the past. That’s in part because miners must grind through more rock to extract coal, and that rock dust contains silica.
Part 90 has been around for decades – it even predates MSHA. But Wiliamson and mine health advocates say the program is underused.
Last year, Williamson says seven miners signed up for the program. This year, he says 34 have opted to participate, most of them in West Virginia and in southern West Virginia in particular.
“If those miners either want to continue to work or they have to because of economic reasons, or whatever the rationale,” he said, “there is this right that’s out there that’s incredibly powerful that can help them preserve what bit of health that they have left.”
As MSHA finalizes a rule to reduce the maximum silica dust exposure for all coal miners – to 50 micrograms per cubic meter per shift – Part 90 is a tool that can benefit those who already have the disease but slow its progression.
“I think it’s hard to argue with a 750 percent increase in the number of miners that are exercising their right,” Williamson said. “We know there’s still many, many, many more miners out there that could benefit from this.”
Miners are suffering from an advanced version of black lung disease known as progressive massive fibrosis. It’s the result of digging at increasingly thin coal seams. That means they’re also cutting into quartz, which creates silica dust. Advanced black lung results from breathing in that blend of silica and coal dust.

This story originally aired in the Oct. 8, 2023 episode of Inside Appalachia.
The coal-producing regions of central Appalachia are at the center of an epidemic of advanced black lung cases among coal miners. New reporting by a retired NPR reporter has shown how federal officials underestimated the sheer number of cases across West Virginia, eastern Kentucky and southwestern Virginia, and now regulators seem to be responding.

He worked with NPR and the PBS series Frontline, and spent more than a year investigating fears that federal regulators and mining companies were failing to protect coal miners from toxic dust.
He and his team obtained documents and data showing federal mine safety officials had evidence of the danger dating back more than 20 years, but never addressed it.
Howard Berkes spent 38 years as an NPR Correspondent. His investigative reporting exposed an epidemic of advanced black lung disease affecting thousands of coal miners, and decades of failure of federal regulators to take steps to prevent it.

In 2018, Berkes reported that more than 2,000 miners were dying of illness related to that toxic dust. Since that story aired, at least four of the miners in it who appeared have died, and at least two have received double-lung transplants. Danny Smith, who was prominently featured, is being assessed for a double-lung transplant.
Danny Smith spent just 12 years mining coal in eastern Kentucky and was diagnosed with the advanced stage of black lung disease at 39. Both are shocking numbers because it used to take decades of mining for coal miners much older to get as sick as this.

Lately, the metallurgical coal industry has been ramping up production to meet global demand, and experts predict even more advanced black lung cases will appear. After years of inaction, though, federal officials are addressing the issue.
Over the summer, the Mine Safety and Health Administration proposed a rule intended to protect coal miners from exposure to silica dust. By the time the comment period closed in September, the draft rule had attracted 157 comments.
Now, Berkes is part of a new investigation into advanced black lung cases that was co-published by Public Health Watch, Louisville Public Media and Mountain State Spotlight. Inside Appalachia Host Mason Adams spoke with Berkes about what his team found.

The transcript below has been lightly edited for clarity.
Adams: So your work in the past, your investigations have in the past have seemed to have resulted in some action. Now MSHA has proposed some new regulations for monitoring silica dust.
Berkes: Yeah, MSHA has taken two very significant steps in this proposed rule. One is to make the exposure limit for silica dust twice as tough as it has been. That was recommended by the National Institute for Occupational Safety and Health back in 1974, and it was recommended again by the Labor Department’s own mine dust advisory committee in 1996.
It’s taken all these years for MSHA to finally adopt what has been long recommended, this tougher limit to exposure to silica dust. That’s a major, major improvement. The second thing that they did is that they decided to regulate overexposure to silica dust directly. In the past, they applied a complicated formula: If a mining company had too much silica dust, then the mining company had to lower the amount of overall mine dust, coal dust and silica dust in the air. That was supposed to bring down the silica dust exposure to an acceptable level. But it’s not a one-to-one relationship.
What we found in our previous investigation was 9,000 overexposures to silica dust, even after the mining companies responded to the regulation that was in effect at the time. So now MSHA is directly regulating silica dust. There can be citations and fines associated with exceeding the silica dust level, that has never happened in the past. So those are two very promising elements of this proposed rule.
This slogan appeared in a Department of Labor document warning about silica dust exposure in workplaces, including mines, in 1997, 26 years before the Mine Safety and Health Administration proposed tougher restrictions on exposure to silica dust.

Adams: There have also been some criticisms of the proposed rule as well.
Berkes: Yeah, mostly on enforcement and oversight. There really is no regular oversight built into the rule. The rule requires mining companies to conduct an enormous amount of sampling of dust, and to record the results of those samples. If they show that there’s overexposure to silica dust, the rule requires that the mining companies then make changes in the way they’re mining so that the silica dust is reduced. There are various things that can be done: they can increase the ventilation, they can make sure that their water sprays on the mining machines are working properly. Those are two key elements in managing dust in coal mines. They can slow down the mining machines and not mine so quickly. They can stop mining a seam that has so much quartz in it. Those are all things that mining companies are required to do once there’s excessive dust. And while they’re doing those things, they’re allowed to continue to mine.
They’re allowed to let miners continue to work in what are dangerous levels of dust. But miners must wear respirators; that has its own set of problems. We’ve interviewed dozens and dozens of miners since 2016, and they all complain about the dust masks not working properly clogging up, inhibiting their breathing, getting too hot, inhibiting their ability to communicate with fellow miners in a very dangerous environment.
There are new helmets out that are very effective for protecting miners from dust, but they can block vision and can block communication in ways that can become dangerous in a coal mine. The main problem with all of this is that MSHA is not going to be watching all the time. Mine inspectors only go into coal mines four times a year, and they’ll do their own sampling when they’re in there. They can ask to see the results of the sampling the mining companies have done. But what this means is that most of the time, there will be no Mine Safety and Health Administration oversight and enforcement of this new rule. It’ll be up to the mining companies. And as coal miner after coal miner after coal miner who we’ve interviewed over the years will tell you, some mining companies have conducted fraudulent sampling over the years. As recently as last year, there was a criminal prosecution in Kentucky for fraudulent dust sampling.

Adams: MSHA has been collecting comments on these proposed rules and they’ve been hearing from miners and advocates in the coal industry. By the time this segment airs, that comment period will have come to a close. But in the last few days, Public Health Watch has published a new investigation with Louisville Public Media and Mountain State Spotlight that calls into question some of MSHA’s projections on which it’s basing this rule. Can you tell us a little bit about that investigation and what your team found?
Berkes: Sure. One of the things that really struck me in the very extensive and dense document that MSHA has produced to justify what it wants to do, is they project how many lives will be saved, and how much disease will be avoided if this new rule is permitted to take effect. What really shocked me was that the projection for coal mines was 63 deaths avoided over 60 years — a little more than one a year — and 244 cases of black lung disease avoided over 60 years. That just doesn’t make sense, given how much disease has actually occurred, which MSHA never mentions in its document. And so we calculated how much disease has occurred by continuing our survey of black lung clinics — both independent clinics and clinics that are funded by the federal government.
What we found, which MSHA doesn’t mention, is that in just the last five years, there have been 1,500 new cases of progressive massive fibrosis, the advanced stage of black lung disease, as reported by these clinics. The total since 2010, since that’s as far back as we go in our survey of clinics, is over 4,000 cases of this horrific, fatal disease. There is no cure. We also, by the way, looked at how many excessive exposures there have been in coal mines in recent years. At the new limit — say the new limit was in place since 2016 — we found over 5,000 excessive exposures at the new limit.
So what these numbers sort of provide is a sense of how serious this situation is, how much over exposure continues to occur, and how much disease continues to occur. That’s not in this proposed rule making. In fact, the numbers presented for silica dust exposure since 2016 by the Mine Safety and Health Administration, they just have numbers from 2016 to 2021. They don’t report how many excessive exposures there were in this document. They report that there were 93 percent of exposures that were within the limit. Well, that sounds like a great number, 93 percent. It sounds like, “Oh, things aren’t so bad.” But that other 7 percent represents more than 5,000 excessive exposures. And because this is such a toxic substance, that’s a lot of potential disease and death. You got to understand that for proposed rule making that this process involves.

So right now, it’s proposed, you mentioned that there’s this comment period that has taken place, that the industry and the public and mine safety advocates and miners get to comment on it. Before there’s a final rule, the Department of Labor has to approve whatever the final rule might be. The Office of Management and Budget has to approve this final rule. We’ve got an election year coming up. There’s often sensitivity from the White House and the Office of Management and Budget on anything that might make voters not vote for candidates that the administration supports or might not vote for the president again, if there’s something in this that offends them.
I’ve seen this happen in the past, where regulatory action was stalled in order to hold off until after an election. There may be other reasons that there could be concerns or objections, budget-wise or otherwise, from the impact on the industry. So it’s important, if you’re going to state your case, to state it as strongly as possible. This rule making does not state that case as strongly as possible. There may be lawsuits from the mining industry over this. So it’s puzzling to me why they didn’t do that. When we asked the Mine Safety Administration, they said, “The comment period exists so that people can tell us what we might need to do better. And this will be one of the things that we consider if people comment on this.
Adams: It’s mind-blowing to think that this represents thousands of people. And behind each of these numbers is a human being. You’ve interviewed dozens of these miners. What have you taken away from those interviews that’s not necessarily reflected in the data?
Berkes: I want to point out that every one of those miners had progressive massive fibrosis. We interviewed miners who had the worst stage of disease. One of the things they all talked about was what their prospects were for the future. Many of them watched fathers, brothers, uncles, grandfathers die of black lung disease, and so they know what they face. This is a tragedy that strikes generations and families: Fathers that won’t see their kids grow up. Fathers that won’t see their daughters at their weddings, won’t see high school graduations. And actually, it’s not just men, there are women miners with this disease as well.
The tragic nature of this is just so astounding and moving and deep. When you talk to a miner with severe disease at advanced stages, they can hardly get a sentence out without coughing or without having to pause for very deep breaths. A miner in my story, Danny Smith, who was diagnosed at 39, he’s 51. Now, he has his grave site picked out. I tried to call him in the last couple of weeks, and his breathing is so labored, he said he can’t get through a phone call. So we were communicating by text message.

Danny was featured in our 2018 story. We’ve been in communication since then. And he’s in terrible shape, and it’s so bad. He loved coal mining, but it’s so bad. He said now he wishes he never stepped foot in the mine. And this was a job he loved. It was a job that made a good life for him and his daughters. He’s a single parent. And there’s an enormous amount of regret, of buying into this bargain of a great life for mining coal. You know, part of what I don’t understand is, in any other workplace in our country, if you had thousands and thousands of people who were sick and dying from a disease, there would be outreach, and there would be response, and there would be response quicker than what has come.
I don’t know why people don’t seem to care about coal miners. There are 40,000 coal miners still working today. I don’t know what it takes to get a response that gets this going in a way that really protects and helps coal miners. But they are people like you and me who have done a job to make lives better for their families. They’re caught up in this whole thing and it’s killing a lot of them.

Adams: Howard Berkes, thank you for your important work on this topic. This is an important subject that has such a deep, deep impact here in central Appalachia. Thanks for coming on Inside Appalachia and speaking with us about it.
Berkes: Always a pleasure to be with you.

MSHA responded with a statement that said the agency was considering “suggestions that the [proposed rule] underestimates the benefit” as it develops a final version of the rule.
***Editor’s Note: The U.S. Mine Safety and Health Administration collected 157 comments on its proposed silica dust rule. A previous version of this story misstated the number of comments the agency received.
A draft rule to protect coal miners from exposure to silica dust garnered more than 5,200 comments from advocates and the American public.
West Virginia’s coal mining communities face an ongoing public health crisis as pneumoconiosis, better known as black lung, affects miners of all ages.
For decades, the nation’s top health officials have urged the Mine Safety and Health Administration (MSHA), the federal agency in charge of mine safety, to adopt strict rules protecting miners from rock dust.
In recent years, the problem has only grown as miners dig through more rock layers to get to less accessible coal, generating deadly silica dust in the process.
Rebecca Shelton, the director of policy at the Appalachian Citizens Law Center, said an MSHA inspector would visit a mine quarterly to take an air sample to test for silica dust.
According to Shelton, those measurements are not taken regularly enough, and she and other experts are unhappy with the current rule, which allows miners to be exposed to silica dust at 100 micrograms per cubic meter of air for an eight-hour shift.
“That 100 microgram standard is not one that’s supported by organizations or entities; other health institutions like the National Institute of Occupational Safety and Health (NIOSH), they for many decades have recommended an exposure level that’s half of that,” Shelton said. “So we’ve known for a long time that this exposure level is too high.”
On July 13, MSHA proposed a rule that would cut the current limit for silica exposure in half, down to 50 micrograms per cubic meter of air for an eight-hour shift. That level matches the standard set by the Occupational Safety and Health Administration.
The new rule would also set up new protocols for sampling and monitoring silica dust exposure levels.
“For example, it now asks that coal operators do some amount of sampling for silica dust. Our understanding is that the agency would still continue its quarterly sampling for silica dust,” Shelton said. “If there are samples that are returned over that 50 micrograms limit, that permissible exposure limit, they will require the operators and mine operators to take corrective actions to reduce that limit.”
However, after decades of inaction, miners and advocates worry about the government following through on these rules. In addition, they don’t think the rule does enough to protect miners.
“One, we feel uncomfortable with the amount of lives that this rule is projected to affect because it’s not many,” Shelton said. “The analyses in the rule actually project that fewer than 100 coal miners’ lives will be saved, while hundreds continue to get sick.”
A public comment period on the new rule was extended to Sept. 11 to allow additional time to develop and submit comments on the proposal.
“It’s quite a variety of folks who have participated in this comment: former miners, organizations like ours who care about the health of miners, and also the industry has participated as well,” Shelton said. “So a lot of public health officials, doctors, a lot of folks who are directly involved in and have been directly involved in treating miners who have been ill with this black lung disease.”
Several desired changes to the rule were consistent throughout the comment process. Commenters want the rule enforced on a more frequent basis and for routine sampling to be performed by MSHA, not coal operators.
“One of the things that we care a lot about is enforcing this new exposure limit based on more frequent and routine sampling conducted by the Mine Safety and Health Administration, and not relying on coal operators sampling, especially because the sampling technology that they have proposed in the rule is an old sampling technology that is easily manipulable by operators in order to try to reduce what that sample returns,” Shelton said.
Commenters also asked for stronger criteria for citations and to provide clear penalties for those violating the rule.
“We do think that the rule needs to have more specificity around the criteria for issuing citations, and penalizing operators who violate the rule,” Shelton said. “The requirements or the process for issuing citations, or what will trigger a citation is not clear in the rule.”
Advocates for miners with black lung also asked that the new rule include provisions to temporarily shut down mines in violation of silica dust limits, rather than allowing them to stay open and rely on miners to use respirators.
“We do not think that it is a bad thing to have respirators and extra protection on hand. We think that absolutely should be the case, but if and when a mine has depth levels that are over that safe exposure limit, we think that production should be shut down and that miners should be withdrawn until corrective actions can take place so that the ventilation plans, the engineering controls, are adequate to reduce dust levels back down to a safer level,” Shelton said.
Lastly, commenters, advocates and miners asked for the rule to phase in better sampling technology.
“Rather than grounding the rule or having the rule rely on the current sampling technology that’s available, that there will be technology-forcing, and that it will adopt better technology as it becomes available,” Shelton said. “We know that these kinds of regulations and rules can produce the demand for better technology. And so we really want to see that change.”
