There is strong evidence that open dust sources (such as vehiclar traffic on unpaved and paved roads, aggregate material handling, and wind erosion) should occupy a prime position in control strategy development in the iron and steel industry. This conclusion is based on comparisons between industry-wide uncontrolled emissions from open dust sources and typically controlled fugitive particulate emissions from major process sources such as steel-making furnaces, blast furnaces, coke ovens, and sinter machines. Preliminary cost-effectiveness (dollars expended per unit mass of reduced particulate emissions) analysis of promising control options for open dust sources indicated that control of these sources might result in significantly improved air quality at a lower cost compared to the control of process sources. This paper presents long-term control efficiency decay curves for chemical dust suppressants applied to unpaved roads at iron and steel plants. The testing program described in this paper is a continuation of an earlier MRI study in the area of the control of open dust sources in the iron and steel industry. While the earlier study indicated that the control of this type of source is more cost-effective than controlling process sources, only recently have researchers begun to study control performance over periods of time greater than a few days after application.
