Problems/Comments

Updated June 5, 2018: The Barwell Island Base End Station Formerly Used Defense Site (FUDS) is located 18 miles southeast of Seward, at the confluence of the Eldorado Narrows and Blying Sound, just outside of Resurrection Bay near Seward, Alaska. In 1925, Barwell Island was withdrawn by the Department of Commerce (DOC) for construction of a lighthouse. In 1941, it was withdrawn for military purposes as part of the harbor defenses of Seward. The site was declared surplus in 1945 and accountability was assumed by the Bureau of Land Management in 1946. There is no indication the DOC ever built a lighthouse and in 1980, Barwell Island became part of Alaska Maritime National Wildlife Refuge, overseen by the United States Fish and Wildlife Service (USFWS), Department of the Interior (DOI). The site remedy (conducted 2010 to 2014) consisted of in-place closure of a former 600-gallon oil UST, removal and disposal of a 600-gallon former gasoline UST, removal and disposal of a 1,500-gallon former water UST, removal and disposal of 20 batteries and approximately 237 feet of lead sheathed cable. After consultation between USACE and US Fish and Wildlife Service, no buried segments of cable would be removed to minimize damage to nesting bird habitat. Following the removal of the gasoline UST and water UST, the excavations were backfilled with native material on-site and re-graded to a grade deemed suitable for the entry and exit of walking birds, as determined by the USFWS representative. No fill was brought to the island. On September 23, 2015, ADEC and USACE signed a Declaration of Project and Property Closure Decision and No Department of Defense Action Indicated for the Formerly Used Defense Site (FUDS) CON-HTRW Project (-01), Barwell Island Base End Station (F10AK0058) in Seward, Alaska.
