Injury rate, 2025
This rate is reportable injury cases per 100 full-time-equivalent workers per year, computed as 200,000 times cases divided by MSHA operator-reported employee-hours. Cases are injuries MSHA graded degree 01 through 07; accident-only events that hurt no one are excluded, and so are contractor injuries, whose hours do not attach to a single mine. Rates begin in 2000, when quarterly employment reporting starts, and are withheld below 20,000 hours in a year.

Health sampling
A sample is a point in time compliance measurement, not an individual exposure history. These figures describe MSHA sampling records and do not establish causation or personal dose.

Respirable coal dust
Respirable coal dust and silica figures cover coal facilities. Dust compliance is measured against the current 1.5 mg/m3 standard; samples predating the 2014 standard are included, so compliance rates are a coarse historical signal.

over MSHA ECV
The excessive concentration value (ECV) is MSHA's own per-sample enforcement threshold, which builds in measurement uncertainty; a sample over its ECV can trigger a citation. The count covers only samples MSHA assigned an ECV.
713 samples taken by MSHA inspectors, 3,685 by the operator.

Noise
The share counts noise samples whose measured dose exceeded the 90 dBA permissible exposure limit. It describes the sampled workplace, not what reached the miner's ear: hearing conservation programs and the hearing protection worn during the shift are recorded separately and are not reflected here.

When citations were contested
Contesting a citation before the Federal Mine Safety and Health Review Commission is a lawful right. These figures state the public outcomes of that process, from MSHA's Contested Violations file.

Source: MSHA Contested Violations file (public record), updated weekly. A dismissed or defaulted contest leaves the citation standing as issued; a vacated or withdrawn citation is removed from the violation record. Latest contest filed 2026-04-02. Vacated and withdrawn citations are removed from the file this view attributes through, so that outcome is slightly undercounted here.
Contested penalties
A reduction or dismissal at the Commission is a lawful outcome of contesting a proposed penalty. Figures are the proposed amount and the amount upheld in the docket's decision.

Where Bluegrass Natural Resources, LLC stands on silica, penalties, and injury rate

MSHA's standard limits respirable silica to 50 micrograms per cubic metre, but MSHA publishes dust and quartz as separate files and never the silica figure itself. We derive it per sample, score it against the limit, and set the operator's injury rate against a benchmark built from the full MSHA operator record. With the 26-year penalty trail, contest posture, and fatality history. Delivered as a PDF with the underlying data as CSV.

The federal record itself stays free on this site. What costs money, and why.
