Linn County Sheriff Bruce Riley reports his deputies responded to a single vehicle crash involving a tractor-trailer on American Drive west of Powerline Road in Halsey.  The truck loaded with sulfuric acid went off the roadway for unknown reasons, and ended up in a field.  The tanker experienced  some minor leakage, but there is no concern of risk to the public.  A Haz-Mat team is standing by while they wait for another truck to respond to off-load the tanker of sulfuric acid.  The roads are open and there is no road blockage at this time. The driver of the truck, Dawn Loftis, 69, from Woodland Washington, received minor injuries.
