MOSIER, Ore. All oil spilled from a derailed Union Pacific tanker train has been removed, state transportation officials said.
The crash happened Friday near Interstate 84. The ensuing leak and fire led to temporary evacuations and highway closures.
Sixteen tanker cars carrying Bakken crude oil derailed, four of those cars caught fire releasing an estimated 42,000 gallons of crude oil into the environment, state transportation officials reported.
The recovered oil was transferred by truck to The Dalles and now staged for transport by rail to Tacoma, its original destination, officials with the Oregon Department of Transportation said.
They announced yesterday that crews have cleaned and decontaminated all of the derailed cars. Empty tanker cars will be transported by truck to Portland.
Once the rail cars have been removed, crews will begin removing contaminated soil and continue other environmental clean-up and monitoring activities.
The derailment also damaged and contaminated the town’s wastewater treatment plant. An estimated 10,000 gallons of oil were removed from the wastewater treatment plant and clean-up continues.
A temporary bypass system is operating while the city works to rebuild the wastewater treatment plant.
The city’s wastewater is being collected and trucked to the Hood River wastewater treatment plant.
Booms remain in place in the Columbia River and Rock Creek as a precautionary measure but no new signs of oil sheen have been seen on the river or other waterways since last weekend.
Union Pacific has identified a preliminary cause for the crash. A bolt that
fastens the rail to the railroad ties may have been at fault, company officials said. A final determination of the cause has not been made.
Rail traffic resumed Sunday, June 5, with trains limited to speeds of 10 mph.
