Public Notice: EPA Begins Five-Year Review of Libby Asbestos Superfund Site in Lincoln County, Montana

Summary

EPA, in cooperation with the state of Montana, is conducting the third five-year review of the Libby Asbestos Superfund site in Lincoln County, Montana. Five-year reviews evaluate remedies to determine whether they remain protective of human health and the environment. This five-year review will be released in 2025.

Vermiculite mining operations just outside of Libby resulted in asbestos contamination in the towns of Libby, Troy, and surrounding areas. Since 2014, EPA has been working to understand and address this contamination. The site is broken into eight areas or Operable Units. Seven of the eight operable units have been remediated, or cleaned. This review will evaluate if the remedies put in place for those areas continues to protect human health and the environment. 

Operable Unit 3, the former mine area, is the only operable unit that has not yet been cleaned, so a remedy for that unit cannot be evaluated in this five-year review. 

The five-year review is an opportunity for you to tell EPA about site conditions and any concerns you have. Community members are encouraged to share information that may be helpful in the five-year review process.
