Field demonstration of an unpaved road dust suppressant
Available options to control unpaved road particulate emissions vary widely in terms of cost, efficiency, and applicability. Chemical unpaved road dust suppressants binders have been recognized as a viable measure for controlling unpaved road dust emission, including the regulated component consisting of particles less than or equal to 10 micrometers in aerodynamic diameter (PM-10). During the 1980s, the U.S. Environmental Protection Agency (EPA) conducted a series of field testing programs at iron and steel plants. These programs had the objective of field determination of various commercially available unpaved road dust suppressants, including petroleum resins, asphalt emulsions, acrylics, lignin sulfonates and salts. These test results were used to support control performance data and predictive models subsequently published in EPA guidance documents. Since the time of the last EPA field program, several new suppressants have been introduced. This paper discusses a field test program to assess the effectiveness of a recently developed suppressant in controlling particulate emissions from vehicle traffic on unpaved roads. The major objective of the program is to demonstrate the effectiveness of the new suppressant relative to dust suppressants evaluated in the EPA test programs. To that end, the methods used to collect samples and to analyze resulting information are analogous to those used in the EPA test programs.
