ANCHORAGE - An estimated 142,800 gallons of diesel fuel spilled from a storage tank on an island in Alaska's remote Aleutian chain.
The Coast Guard says 1,000 gallons from the Monday spill on Adak Island entered a creek and flowed into a small boat harbor.
The Alaska Department of Environmental Conservation says the fuel flowed from an underground storage tank as a ship moored at a pier pumped fuel to the tank.
The flow reached a drainage system that collects water from around the underground tanks and sends it into the creek. The amount overwhelmed the system's oil and water separator.
