To help meet the requirements of the 1990 Clean Air Act Amendments, the US Department of Energy (DOE) sponsored a project entitled Comprehensive Characterization of Toxic Emissions from Coal-Fired Power Plants. The Energy and Environmental Research Center was contracted to review reports discussing air toxic emissions from eight power plants as Phase 1 of the project. Additional field tests were planned as Phase 2 and are under way. The objective of the project is to provide an independent review of reports produced from the air toxic emissions study, evaluate the scientific validity of the conclusions, identify significant correlations between emissions and fuel or process parameters, compare the data with available results from Electric Power Research Institute (EPRI) studies, make recommendations for future studies, and complete a combined report that summarizes Phase 1, Phase 2, and EPRI findings.
