| Abstract |
To determine the air pollution impact of selected fugitive dust sources, a national emission inventory on a county-by-county basis was developed. Source categories included were unpaved roads, unpaved airstrips, heavy construction sites (road and building construction), and agricultural land tilling. Emission factors, which include correction factors to adjust for local climatic conditions and properties of emitting surfaces were calculated for each county based on the results from EPA Contract No. 68-02-0619. Measures of the extent of activity for each category were derived from available data. |
