This project involved an update of air dispersion modeling work that was performed several years ago with an outdated dispersion model. Emissions of polychlorinated biphenyls (PCBs), particulate matter, and trichloroethylene (TCE) from sources at the National Electric Coil Facility in Dayhoit, Kentucky, were modeled using the EPA's latest version of AERMOD.
Shown below is an isopleth map depicting annual average TCE concentrations in the vicinity of Dayhoit, Kentucky. A high quality PDF version of the map is available here.
