The purpose of the study is to assess the risk caused by dust emissions associated with proposed remedial actions considered for the Vertac Chemical Corporation site in Jacksonville, Arkansas. Much of the site is contaminated with 2,3,7,8-TCDD as a result of the materials handling, waste disposal, and other operations associated with the pesticide production which has occurred at the site since the 1950's. The proposed remedial action involves excavation of the contaminated areas and redisposal in a secure landfill. These actions would disturb the soil, creating the potential for dust emissions. The study estimates the possible emission rates, uses dispersion models to predict resulting off-site air concentrations, and finally, calculates the exposure/risks caused by these emissions.
