EPA and DEQ request comments on Libby Asbestos Superfund Site Operable Unit 8 Proposed Deletion

Operable Unit 8 of the Libby Asbestos Superfund site is being proposed to delete from  the National Priorities List. Comments on this action will be accepted from May 14-June 14.

Operable Unit 8 (OU8) consists of roadways and highways in and between the cities of Libby and Troy, including U.S. Highway 2, MT Highway 37 and county roads. These roads and highways have been cleaned up through remedial actions at other Operable Units of the site.

OU8 is considered protective of human health and the environment and does not require additional cleanup. OU8 is therefore eligible to be partially deleted from the site. Operations and maintenance activities, including reviews, will continue to evaluate and ensure protectiveness at OU8 into the future.

EPA Announces Final Cleanup Plan

Investigation or Cleanup Complete at 7,100 of 8,000 Properties

EPA has selected a final remedial plan for the communities of Libby and Troy at the Libby Asbestos Superfund site. Under this plan, EPA will continue to replace contaminated soil and remove and dispose of accessible contaminated building materials at remaining properties. EPA and the Montana Department of Environmental Quality will also work closely with community members to develop and implement a robust long-term plan to manage Libby Amphibole asbestos that might be encountered following cleanup and to ensure that the remedy remains protective.

The final remedy is essentially the same as the preferred alternative described in EPA’s proposed plan and was selected following a 90-day public comment period and careful review of comments received. In response to public comments received regarding institutional controls, EPA and the Montana Department of Environmental Quality are participating in an Institutional Control (IC) steering committee organized by Lincoln County to relay community concerns and provide input on the development of the ICs. EPA also will accept public comment on the final IC work plan.

The Record of Decision, including a summary of responses to public comments, is available in Site Documents and at the following locations: EPA Information Center, 108 E. 9th Street, Libby, 293 6194 Lincoln County Library in Libby, 220 West 6th Street, 293-2778 Lincoln County Library in Troy, 207 3rd Street, 295 4040
