MSHA sampling at SUNNYSIDE WASTE COAL SITE shows respirable coal dust averaging 0.21 mg/m3 (99% compliant) across 313 samples.
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.0.21
