Introduction The United States Army Corps of Engineers (USACE) is conducting investigation and remediation activities at the Former Camp Adair /Adair Air Force Station (Camp Adair), located approximately nine miles north of Corvallis, Oregon under the authorities of the Defense Environmental Restoration Program for Formerly Used Defense Sites (DERP-FUDS). Under the DERP-FUDS program, USACE has the following existing or former projects for Camp Adair (Site No. F10OR002900): • Containerized Hazardous, Toxic, or Radioactive Waste (CON/HTRW) – Project No. F10OR002901 was approved in 1992. Ten Underground Storage Tanks (USTs) were removed in 1994 (EPJCE, 1995), although No [further] Department of Defense Action Indicated (NDAI) status was not achieved. This project was closed in 2006. • Building Demolition/Debris Removal (BD/DR) – Project No. F10OR002902 was approved in 1992. One high brick chimney was demolished and disposed, one partially completed mobile missile facility was filled, 10 man-holes in the Camp Adair cantonment area were filled, and 33 manhole covers were replaced in the Camp Adair cantonment area. No additional work was identified. This project is currently closed. • Military Munitions Response Program (MMRP) – Project No. F10OR002903 was approved in 2000. An MMRP Site Inspection Report for Camp Adair was completed in 2007 (USACE, 2007b). This project is currently in progress. • Hazardous, Toxic, or Radioactive Waste (HTRW) – Project No. F10OR002904 was approved in 2007. A Site Investigation Report was completed in 2012 followed by a Background Desktop Exercise Technical Memorandum in 2014. This project is currently in progress. Under the HTRW and CON/HTRW projects, USACE has performed multiple investigation and cleanup actions. These activities have included underground storage tank (UST) decommissioning activities, a draft Preliminary Assessment (PA; USACE, 2007a), an HTRW Site Investigation (SI; USACE, 2011a), and a Background Desktop Exercise
