The Libby OU4 and OU7 Operations & Maintenance (O&M) Program includes these three documents: Institutional Control Implementation and Assurance Plan (ICIAP), O&M Plan, and O&M Manual. The development and finalization of the ICIAP, O&M Plan and O&M Manual were a collaborative effort between EPA, DEQ and Lincoln County.
- Institutional Control Implementation and Assurance Plan (ICIAP) is a plan that discusses the Institutional Controls (IC) necessary to maintain the remedy or minimize encounters of Libby Amphibole Asbestos (LA). ICs are nonengineered instruments such as administrative, programmatic and legal controls that help minimize the potential for human exposure to contaminations and/or protect the integrity of the remedy. Final OU4 and OU7 ICIAP - March 2020
- O&M Plan outlines the administrative, financial and technical aspects of the O&M Program and the requirements for inspecting, operating and maintaining the remedial action at OU4 and OU7. Final OU4 and OU7 O&M Plan - April 2020
- The O&M Manual details protocols and procedures for implementing routine O&M activities. The O&M Manual includes detailed information used to operate and maintain the remedy, while the O&M Plan is designed to be more of a management document. This manual is intended to be a “living” document whereby the most recent guidance and operating information is included for use by DEQ staff and delegated authorities. It will be evaluated and updated annually.
As we continue to adjust to the evolving COVID-19 situation, EPA and the Montana DEQ are taking necessary steps to ensure that decisions about ongoing cleanup activities at Superfund sites are made with the health and safety of communities, EPA staff, state and tribal partners, and contractors as the priority. EPA and Montana DEQ decided to postpone the transfer of responsibility for operation and maintenance (O&M) activity at the residential and commercial areas of the Libby Asbestos Superfund site due to limitations associated with in-person coordination during the ongoing response to the COVID-19 pandemic.
EPA will work closely with Montana DEQ through the O&M transition until local health conditions allow for the planned transition process to move forward. This temporary delay will not affect or change any on-the-ground activities or remedies in place at the site. EPA and Montana DEQ will continue to collaborate on ongoing site work to ensure a smooth transition. EPA and Montana DEQ will share updated information with partners and the public on the timeframe for the formal transition as soon as it is available.
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
