The report gives results of a study of particulate control for fugitive dust. Study results indicate that many Air Quality Control Regions (AQCRs) do not meet ambient air standards for particulates. In a majority of these ACQRs, the emissions from fugitive dust sources are higher than those from nonfugitive sources. In most cases, unpaved roads provide the greatest amount of emissions. Agricultural tilling and construction activity also contribute substantial amounts. The reentrainment of particles from paved roads also provides large quantities in urban areas. The study concludes that present control strategies for fugitive sources are inadequate. Even with reductions in fugitive emissions of 50% for unpaved roads, 40% for agricultural tilling, and 30% for construction, most of the 150 AQCRs that exceeded total suspended particulate standards will still probably exceed them. In addition, area sources will still dominate all other emissions sources. Thus more effective control measures must be developed.
