It is therefore subject to change as new information becomes available. We recommend contacting the assigned project staff prior to making decisions based on this information.


Abbreviated Preliminary Assessments are being completed for up to 30 areas of interest on the island. The majority of the features of concern identified are fuel tanks and pipelines, transformers, batteries, barrel dumps and burn pits. These sites will proceed to Site Investigations in the future. Removal Actions may occur if there is an identified threat that can be mitigated through focused removal. The Corps is planning for a removal in 2016 for a tar/asphalt area that has entrapped birds.

4/21/2016 CERCLA Removal Action Plan Submit approval letter to USACE for the Source and incidental contaminant Removal Action Work plan for Attu Island. The plan identifies removal actions for AOI#1 "Navy Town: Beach Road Storage and Docking Area and AOI#4 "Navy Town: Aboveground Storage tank Disposal Area". At AOI#1 contamination associated with a former burn area will be excavated and removed from the island. At AOI#4 pooled tar and associated AST's will be consolidated and removed from the island. Any contaminated soil underlying the tar will also be excavated and removed from the island. The Removal Action at AOI#4 is intended to prevent additional bird entrapment in the pooled tar.
