(Denver, Colo. -- November 20, 2015) The U.S. Environmental Protection Agency (EPA) today announced release of the final human health risk assessment specific to the Libby Asbestos Superfund site.

EPA completed its rigorous scientific review of toxicity values and a draft risk assessment in December 2014. Comments received during a public comment period for a proposed cleanup decision did not change the agency's ultimate conclusion: it is possible to live and work in Libby and Troy without excessive exposure to asbestos.

Finalization of the risk assessment confirms that EPA's indoor and outdoor cleanups have significantly reduced risk from exposure to asbestos. EPA has removed major sources of Libby Amphibole (LA) asbestos in and around Libby and Troy.

Higher levels of LA could be found at some properties where owners have not yet provided access and in areas located on and near the former vermiculite mine. EPA has investigated more than 7,000 properties within the site but is still awaiting access to about 700 properties. These property owners are encouraged to contact EPA's Libby Information Office, 406-293-6194, to schedule a property investigation.

The final risk assessment will be posted on EPA's web site for the Libby site, www.epa.gov/superfund/libby-asbestos. If you would like to receive a copy of the final risk assessment please contact Richard Mylott, 303-312-6654, mylott.richard@epa.gov or Jennifer Lane, EPA Region 8 Community Involvement Coordinator, 303-312-6813 or lane.jennifer@epa.gov
