Imminent-danger orders
A Section 107(a) order removes miners from an area when an inspector finds an imminent danger. Each order is lifted once the condition is corrected, so this counts orders issued, not orders now in effect.

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.
1,512 samples taken by MSHA inspectors, 6,125 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.

Metal and nonmetal contaminants (personal samples)
Many samples are screening measurements of substances with no applicable exposure limit; they are counted as samples but excluded from every over-limit figure. Over-limit shares use only limit-tested samples.

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.
1,164 citations taken to the federal commission · 20% of citations on record
  • Settled 1,059 · 91%
  • Stood as issued 33 · 3%
  • Vacated or withdrawn 3 · 0%
  • Still open 69 · 6%
69%
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
$2.3M proposed, $1.4M 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 2026-03-08. 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.

GCC Rio Grande Inc · Struck against a moving object

A delivery driver employed by a water supply vendor was in route to the facility when the tanker truck overturned and slid off the road. Investigation ongoing

February 22, 2025 SD · Metal/Non-Metal prep plant foreman, supervisor, mill plant supervisor, kiln supervisor Fatality · POWERED HAULAGE
GCC Dacotah Inc · Caught in, under or between (Not Elsewhere Classified)

A miner received fatal injuries. After a bridge collapsed that the miner was operating a skid steer loader on. The miner was clearing refractory brick form a rotary kiln. The bridge that was installed by the property owner collapsed. The skid steer fell approximately 10 feet into a hopper, causing the payload of brick to engulf the operator causing fatal wounds.

Where GCC SAB de CV 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.
