A small amount of a corrosive chemical was released early Wednesday when a Union Pacific freight train derailed in Eastern Oregon’s Grande Ronde Valley.
The railroad said it was a chemical mixture, and the primary ingredient was sodium hydroxide, an industrial chemical known as lye.
The State Police said in a statement there was “no significant hazardous material leak.”
