Emissions from the Crushed Granite Industry State of the Art - US EPA
A typical crushed granite plant has a production rate of 450 metric tons/hr and emits dust at the rate of 6.9 kg/hr respi- rable particulate and 49 kg/hr total particulate. To assess the source severity, the ratio of the maximum ground level concentration at the representative plant boundary to the pollutant hazard factor is used.
