Problems/Comments

U.S. Military interest in Yakutat began by Executive Order in 1929, with the creation of the Yakutat Bay Naval Reservation. Occupation by the military began in 1939 when the Civil Aeronautic Administration (CAA) began to develop a landing field. Construction of the Yakutat Air Base began in 1940, and was completed in 1943 with a total area of approximately 46,080 acres. Military facilities were established in Yakutat because of its strategic geographic location. The Yakutat Air Base was operated as an auxiliary airfield during World War II capable of supporting pursuit and bombardment aircraft. No aircraft were assigned permanently to Yakutat; instead, the base served as a ferrying post and temporary station for aircraft squadrons, and as a refueling stop between the 48 contiguous states and points in Alaska. The air base also hosted large military vessels in Monti Bay. The air base was placed on caretaker status in April 1944, declared surplus in December 1945, and ceased operations in 1946. Parts of the property of the Air Force Base was relinquished to the U.S. Department of the Interior, Bureau of Land Management (BLM) , the CAA (now known as the Federal Aviation Administration (FAA), the Department of the Navy, and the Tongass National Forest. In 1960, the U.S. Air Force acquired lands from the U.S. Forest Service and the State of Alaska Division of Lands to construct a radio link between Cape Yakataga and Hoonah. The Ocean Cape Radio Relay (OCRR) Station facility served as a tropospheric communications station as part of the Ballistic Missile Early Warning System under the White Alice Communications System (WACS). The site, located on the Phipps Peninsula at the end of Point Carrew Road, approximately 5 miles west of the city of Yakutat, included industrial buildings, support facilities, water and fuel storage tanks, pipelines, billboard antennae, a bridge, roads, and utility lines. The facilities were leased to Recording Company America Alaska Communications, Inc. between 1974 and 1976. The OCRR Station was declared excess by the U.S. Air Force in June 1976. This land was relinquished to the BLM in 1977, and conveyed to the Tlingit tribe in 1983. The United States Army Corps of Engineers (USACE) carried out cleanup operations around Yakutat in 1984. Remaining Department of Defense (DoD) facilities were slated to be removed. Although no project report is available, it appears that most of the infrastructure was removed at that time. Multiple remedial investigations (RIs) have been conducted at the former Yakutat Air Base since the 1984 cleanup operations. The RIs typically included select areas of concern and focused on sampling and analysis of media including surface soil, subsurface soil, sediment, surface water and groundwater for suspected contaminants. In addition, multiple geophysical studies have been performed to locate buried objects such as piping, tanks and drums; and debris within local surface water bodies. Debris removal activities have been conducted at Ocean Cape by the USACE and the Yakutat Tlingit Tribe. Based on information gathered about potential contamination resulting from military use of the Army Air Base during World War II (from 1940 to 1946), 67 individual potential contaminant source areas of concern (AOC) have been identified. 14 of the sites have been investigated by the USACE have been found to pose no unacceptable risk to human health or the environment. One site was investigated and determined to not be eligible for cleanup by the USACE, and will be addressed by other parties. The 52 remaining AOCs will be addressed in the future by USACE with input from ADEC and stakeholders. This will include reorganizing the AOCs into smaller, discrete projects that can be more efficiently executed. The ADEC, USACE, and other stakeholders are still in the process of identifying the complete list of potentially-contaminated sites associated with the Former Yakutat Air Base.

Update or Other Action

A draft remedial investigation/feasibility study was reviewed. The ADEC determined that each site had insufficient site characterization data available to select appropriate remedies or to effectively evaluate them against CERCLA criteria. Based on the information provided, the Feasibility Study is premature. ADEC recommended that the USACE not incur further expense to finalize the document until further site characterization was done. Work should occur to identify the data gaps and resolve them before any additional actions are taken.
