Asbestos-Contaminated Vermiculite
Continued from: Asbestos Exposure
The sites listed on this page received asbestos-contaminated vermiculite from Libby, Montana, and are considered potential toxic hazard areas.*
Many more sites received materials from the Libby Montana facility, but those listed below were selected by the Agency for Toxic Substance and Disease Registry (ATSDR) based on the following two criteria:
- The U.S. Environmental Protection Agency (EPA) mandated further action at the site on the basis of current contamination; or
- The site was an exfoliation facility that processed roughly 100,000 tons or more of vermiculite from the Libby mine. Exfoliation is a process in which vermiculite ore is heated at high temperatures to expand or "pop" it. These facilities are of particular concern because exfoliation causes higher amounts of asbestos to be released than other processing methods.
