The Environmental Protection Agency has added a portion of Bradford Island in the Bonneville Lock & Dam complex to the National Priorities List.  The section on the northeastern side of Bradford Island is not in a public area and was formerly used as a landfill, pistol range and sandblast area.  A portion of this section of the island has been set aside to be managed as a wildlife habitat, while the remaining area is currently used for industrial purposes.  The NPL is a list of sites across the country which are the highest priority for Superfund cleanup.  The U.S. Army Corps of Engineers will remain the lead federal agency as it works with other agencies including the EPA, Oregon Department of Environmental Quality, Washington Department of Ecology, tribal nations, and the U.S. Fish and Wildlife Service to determine the best course of action to restore the site to environmentally acceptable levels.  In 2007, the Corps removed 65 tons of sediment from an eight-tenth of an acre area along the shoreline of Bradford Island.
