A rail car in the area of Cleves and Whitewater Township is longer leaking styrene, but evacuation orders and the closure of roads and businesses in the area remain in place.
While the leak coming from the train car appeared to be a gas, the National Institute of Environmental Health Sciences says styrene is a colorless, flammable liquid used to make plastics and rubber.
An evacuation order remains in place after a railcar in Ohio began leaking styrene on Tuesday. While the leak has stopped, roads in the area are also staying closed.
