The state Department of Ecology says it has fined the Boeing Co. more than $100,000 for a 300-gallon jet fuel spill in to the Duwamish waterway.
According to the department, the spill happened in May, 2010 at Boeing fuel terminal in south Seattle. It says that workers were delivering to a storage tank when they noticed the spill. However, they thought the spill had been contained to Boeing's property.
A few days after the spill, they noticed the fuel had gone into the water and contacted state and federal authorities. By then, the oil was spread too thin to clean up.
It was later determined that an open valve was the source of the leak.
Boeing vice president Mary Armstrong says the aerospace giant fully restored the shoreline by excavating the contaminated sediment, among other actions.
