Problems/Comments

The former Loran Station was constructed between 1948 and 1950 to support US Naval and Coast Guard navigation in and out of the Aleutian Islands. The station was closed in 1979. Three JP-5 tanks were removed separately from this site. Potentially hazardous debris was removed in 1990 and 1991. Institutional controls selected in OU A ROD. Future land use is restricted and deed restriction or restrictive covenants have been implemented. Visual site inspections are conducted annually to ensure the effectiveness of institutional controls. Site conditions are assessed at least every five years for the need to take additional action or reduce controls, as appropriate. Draft Close Out Report for Partial Delisting submitted for Department review on June 16. Comments were submitted to the Navy on August 16.

3/6/2020 Institutional Control Periodic Reporting The U.S. Navy (Navy) is the lead agency and responsible party for monitoring and ensuring the effectiveness of the institutional controls (ICs) selected in the Operable Unit (OU) A Record of Decision (ROD) and the OU B-1 ROD at the Former Naval Complex, Adak, Alaska. The Navy is required to conduct monitoring for as long as site conditions pose an unacceptable risk for unlimited use and unrestricted exposure to the community and the environment. The ICs will remain in place until those conditions are met. If any of the ICs are ineffective or if significant failures pose harmful risks to the community and the environment, the Navy is responsible for additional remedial actions. Repairs to ICs identified by periodic inspections will be conducted by the Navy approximately every 3 to 5 years, if needed. If severe or unusual failures of ICs are observed, the Navy will conduct additional emergency repairs at that time. Because it has been shown that ICs have generally remained effective since 2005, reductions to the monitoring program began in 2013. Currently, 28 sites are inspected biennially (including Parcel 4) with 39 sites (including 12 remote OU B-1 sites) inspected every 5 years. Darren Mulkey
