Hazardous materials experts were working Thursday to drain the leaking tank into a recovery tank. The leak forced the evacuation of about 100 families beginning Wednesday, May 8, 2013. The mandatory and voluntary evacuation was lifted late Thursday. An official said it will take up to two days to drain the tank. (AP Photo/Bayer CropScience, Monty Christian) NO SALES
