Penalty disposition
Differences between proposed and paid penalties reflect both settlements and conference reductions and amounts still owed. Outstanding is the balance currently owed.

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.
60 samples taken by MSHA inspectors, 3 by the operator.

  • BULLDOZER OPERATOR11

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.

S&S designation survived the contest
Counts a Significant & Substantial citation as surviving when a settlement or judge's decision kept the designation, or the contest was dismissed or defaulted so the citation stands as issued. Vacated and withdrawn citations, and settlements that removed the designation, count against.

Penalty reduction in decided contests
$63K proposed, $38K after decisions · industry: 39%
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 A dismissed or defaulted contest leaves the citation standing as issued; a vacated or withdrawn citation is removed from the violation record.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 2019-07-16. Vacated and withdrawn citations are removed from the file this view attributes through, so that outcome is slightly undercounted here.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 Leonard Hendrickson 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.
