Abstract The Environmental Protection Agency (EPA) has determined that vermiculite ore mined at the former W.R. Grace vermiculite mine in Libby, Montana, is contaminated with asbestos. Libby ore was processed at vermiculite exfoliation plants across the country including one located in Spokane, Washington. EPA Region 10 conducted a three phase study at the Spokane vermiculite exfoliation plant to determine if asbestos fibers in the soil at the site could become airborne when the soil was disturbed. First, soil samples were taken from several locations within the site boundary and analyzed using polarized light microscopy and X-ray diffraction. Analysis revealed that most of the asbestos in the soil is similar to the amphibole asbestos that occurs in vermiculite from Libby, Montana. In phase two, twelve soil specimens were collected from the site and eleven were agitated inside a laboratory enclosure equipped with air monitoring equipment. During phase three, EPA staff collected eighteen air samples while performing property maintenance and excavation tasks at two locations on-site.
