Description:
Control techniques are reviewed for applicability to fugitive particulate emissions from hazardous waste sites. Techniques judged applicable include chemical stabilization (40 to 100 percent efficiency, $520/acre-yr to $2,720/acre-yr), wet suppression (25 to 90 percent efficiency, $365/acre-yr to $1,270/acre-yr), physical covering (30 to 100 percent efficiency, $0.01/sq.m to $65/sq.m), vegetative covering (50 to 80 percent efficiency, $0.11 /sq.m to $3.96/sq.m), and windscreens (30 to 80 percent efficiency, $18.01/sq.m to $26.90/sq.m of screen). Reducing vehicle speed on unpaved roads can reduce emissions by 25 to 80 percent depending on initial conditions. Supporting reviews are included for soil characteristics, emission factors, and dispersion processes that generate and distribute fugitive particulate matter. A method is described to estimate degree of contamination (DOC) of soil particles based on the contaminating chemical's water solubility and the soil's organic carbon content. A first-order decay process is included. Five example sites are described and estimates made of uncontrolled and controlled downwind concentrations of hazardous constituents. Annual averages are in the attogram to nanogram per cubic meter range. Ranges for control and efficiency costs for each site are included.
