Description:
The report gives results of air quality modeling to assess the impact of burning solvent-refined coal (SRC) instead of conventional coal in three power plants which exceeded National Ambient Air Quality Standards when burning conventional coal. The EPA CRSTER Gaussian plume model with minor modifications was used to calculate ambient air pollution concentrations (for SO2, NOx, and particulates) when (a) conventional coal and (b) SRC were burned. SRC test burn emissions data were used to determine emission factors for the three pollutants when burning SRC at each plant . The most significant impact of switching from conventional coal to SRC was the reduction of SO2 and particulate concentrations at each plant. The highest 20 maximum 24-hour SO2 concentrations were reduced by 60-75%. At all three plants, the annual mean particulate concentrations were reduced to essentially background levels when SRC was burned.
