This rate is recorded citations divided by MSHA inspection hours, per 100 hours. It reflects inspection effort, not mine size or production.Coal Stone #10 has $62K in proposed MSHA penalties and $1K outstanding across 14 contested dockets.
ⓘ
Differences between proposed and paid penalties reflect both settlements and conference reductions and amounts still owed. Outstanding is the balance currently owed.MSHA sampling at Coal Stone #10 shows respirable coal dust averaging 0.26 mg/m3 (98% compliant) across 204 samples.
ⓘ
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 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.ⓘ
Citations per million reported employee-hours. Rates begin in 2000, when MSHA's quarterly employment data starts; earlier incidents are counted but cannot be rate-adjusted. Quarters under 100,000 reported hours are greyed: too few hours for a stable rate.| Quarter | Hours worked | Citations | S&S | Per 1M hrs |
