A comprehensive, multipathway health-based risk assessment study was performed for routine air emissions from three combustion sources collocated at a rural site. The sources included a proposed 2250 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 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. 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. There are currently insufficient data to quantify risks associated with carcinogenic synergies. Sensitivity analyses were conducted to evaluate the effect due to uncertainties in emissions, toxicity, deposition, and bioaccumulation. Generally, these sensitivity analyses suggest that actual exposure and risks are likely to be less than those estimated in the study.
