MSHA sampling at Lenig & Kosmer Coal Washery shows 100% of 93 respirable coal dust samples met the 1.5 mg/m3 standard.

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.
93 samples taken by MSHA inspectors, 0 by the operator.
Most-sampled occupations
  • HIGHLIFT OPERATOR/FRONT END LOADER50
  • DIESTER TABLE OPERATOR19
  • CLEANING PLANT OPERATOR14

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.

Source: MSHA quarterly employment and production, updated weekly.

Lenig & Kosmer Coal Washery sits in Northumberland County, Pennsylvania, where the Census mining category is 0.6% of county employment.

Local economic context
County figures come from the US Census Bureau's American Community Survey, 5-year pooled estimates, so the 2023 vintage covers 2019 through 2023. The Census category is 'mining, quarrying, and oil and gas extraction', which is broader than MSHA jurisdiction and includes oil and gas workers no mine employs. These figures describe the surrounding county, not this mine, and are not a factor in any specific incident.

Quarterly safety rates
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.
