15.1 Sector Descriptions and Overview

Fugitive dust emissions from agricultural tilling include the airborne soil particulate emissions produced during the preparation of agricultural lands for planting. Dust kicked up by animals refers to the dust emitted from different types of livestock feet. These emissions are primarily considered to be made by cattle and swine, but poultry emissions of dust are also examined. Fugitive dust emissions from both agricultural tilling and livestock feet are estimated for PM10-PRI,cPM10-FIL, PM25-PRI, and PM25-FIL. Since there are no PM-CON emissions for this category, PM10-PRI emissions are equal to PM10-FIL emissions and PM25-PRI emissions are equal to PM25-FIL. Table 15.1 shows the SCCs assigned to the various ag tilling and livestock feet; SCC level 1 are “Miscellaneous Area Sources” for all SCCs.
