Abstract |
This report describes a study of atmospheric emissions from the crushed granite industry. The potential environmental effect of this emission source was evaluated using source severity, defined as the ratio of the maximum time-averaged ground level concentration of a pollutant at a representative plant boundary to a hazard factor. The hazard factor is the ambient air quality standard for criteria pollutants and an adjusted threshold limit value for noncriteria pollutants. Pollutants are emitted from several operations including drilling, blasting, transport on unpaved roads, crushing, screening, conveying, and stockpiling. Emission factors are determined for particulates emitted from trace operations. The emission rate of respirable particulates (<7 micrometers is 6.9 kg/hr). The major hazardous constituent in the dust is free silica (27.2% by weight). |
