Task 2.3 - Review and Assessment of Results From the Comprehensive Characterization of Toxic Emissions From Coal-Fired Power Plants

To help meet the requirements of the 1990 Clean Air Act Amendments, the U.S. Department of Energy (DOE) sponsored Phase I of a study entitled "Comprehensive Characterization of Toxic - Emissions from Coal-Fired Power Plants" in 1992. Final reports which detail air toxic emissions from eight power plants (nine conilgurations) were completed by the contractors. The Energy & Environmental Research Center (EERC) served as an independent third-party reviewer of these reports; it has completed the activities as outlined for the initial review process and has prepared two reports. The fiist report, entitled "A Comprehensive Assessment of Toxic Emissions from Coal-Fired Power Plants: Phase I Results from the U.S. Department of Energy Study" was published in September 1996 and is available to the public and private sectors through the U. S. Department of Energy (DOE) Federal Energy Technology Center (FETC) at Pittsburgh. This report surnmar izes and evaluates the stack emission data. The second report prepared by the EERC, entitled "A Comprehensive Assessment of Toxic Emission from Coal-Fired Power Plants: Statistical Correlations from the Combined DOE and EPRI Field Test Data," details empirical correlations derived horn the Phase I DOE data and the Electric Power Research Institute (EPIU) PISCES (Power Plant Integrated Systems: Chemical Emissions Studies) data. The objective of the project was to provide an independent review of the Phase I data, evaluate the scientific validity of the conclusions, identify significant correlations between emissions and fuel or process parameters, compare the data with available data from EPRI studies, make recommendations for future studies, and complete a combined report that summarizes Phase I, Phase II, and EPRI findings
