The train cars were carrying hot asphalt and molten sulfur, Stillwater County Disaster and Emergency Services said. Officials shut down drinking water intakes downstream while they evaluated the danger after the 6 a.m. accident. An Associated Press reporter witnessed a yellow substance coming out of some of the tank cars. David Stamey, the county's chief of emergency services, said there was no immediate danger for the crews working at the site, and the hazardous material was being diluted by the swollen river. There were three asphalt cars and four sulfur cars in the river.
Coordinated action critical to preventing flooding in Portland, Vancouver
Without careful coordination for flood risk management throughout the water year, the Columbia River would have hit a stage of 25 feet at Vancouver in June, a height not seen in the river in springtime since 1956. That level would be considered ‘major flood stage’, as determined by the National Weather Service. Evidence of the same storm’s power was seen further south in the damaging flooding along the Yellowstone River in northern Wyoming.
