Maine environmental officials say reports of “dirty rain” in the state on Friday were not related to the Ohio train disaster.

Some Mainers snapped photos of dirty windshields and windows, but experts say the storm actually picked up dust from dust storms in Oklahoma earlier in the week.

Maine DEP Division Director Andrew Johnson says testing shows vinyl chlorine released from the train derailment and fire in East Palestine, Ohio is not present in the atmosphere above Maine.

Environmental officials don’t expect the state to be impacted by the chemicals released from the fire, and that if that were the case, it likely would have happened already.
