WALLA WALLA — About 660 gallons of diesel fuel spilled near the Columbia River south of Wallula after a Union Pacific train derailed about 3:20 a.m. Wednesday, Nov. 6.
Stephanie May, a communications manager for the Washington State Department of Ecology, said the department was informed about the derailment about 4 a.m., but was told there was no indication of a spill at the time.
May said the first response to the train’s derailment came at 3:40 a.m., when a Union Pacific contractor arrived on site. About 6:30 a.m. the Department of Ecology received a call reporting the derailment caused a spill.
Later the Pacific Union contractor placed the first boom, a floating device used to contain oil spills and other chemicals, in the Columbia River about 7:30 a.m.
