The report presents an overview of a comprehensive, multipathway health-based risk assessment study performed for routine air emissions from three combustion sources collocated at a rural site. The sources included a proposed 2,250 ton/day municipal waste resource recovery facility, an existing 558-MW coal fired power plant and a proposed 750-MW oil/gas-fired combustion turbine power plant. State-of-the-art risk assessment methods were developed to determine human exposure through inhalation of contaminated air (direct emissions as well as resuspended contaminated soil) and ingestion of contaminated crops, livestock, fish, water, and soil. Carcinogenic and noncarcinogenic effects to a most exposed individual (MEI) and an average exposed farmer, who both eat locally-derived food, were estimated. In addition to the classical assessment, potential risks associated with toxics formation from plume mixing as well as enhanced risk associated with carcinogenic synergies between pollutants were addressed.
