Case Description

Adak Petroleum, LLC owned a 4.8 million gallon underground fuel tank which is part of the Adak fuel storage tank facility on Adak Island in central Aleutian Islands of Alaska. On January 11, 2010 fuel was being transferred from a tanker the adjacent loading dock when Adak's fuel tank was overfilled, releasing approximately 142,000 gallons of diesel fuel to navigable water. Oil from the discharge was found over 2 km of Helmet Creek and 205 acres of associated riparian habit. Fuel from the release entered Helmet Creek, and flowed into the small boat harbor at Sweeper Cove. Oil from the discharge was found over approximately 9.2 acres of marine habitat and shoreline in Sweeper Cove. Fuel from the incident caused injuries to natural resources, including the oiling of birds, fish, and their habitats, and also had an impact upon recreational uses of natural resources and other public resources.
