In November 2018, EPA completed cleanups of asbestos at residential and commercial properties in Libby and Troy, Montana. The cleanup is associated with the W.R. Grace vermiculite mine that became a Superfund site in 1999. Over the past 19 years, The City of Libby came together with EPA, Montana Department of Environmental Quality, Lincoln County, and many other federal and state partners and community organizations, to develop a coordinated approach for the area’s cleanup and redevelopment.
Throughout the course of the cleanup, EPA has investigated over 8,100 properties and removed and replaced more than one million cubic yards of contaminated soils. While EPA activities at the W.R. Grace Mine will continue into the near future, long-term operations and maintenance of the site will transfer to the state in 2020.
