PEORIA  COUNTY - A big scare for a local hazmat crew. Two anhydrous ammonia tanks toppled off their trailer and into a ditch at Toute 90 and Duncan Road near Princeville. Peoria's Fire Crews used reverse 911 to call residents to tell them that there could be a leak.   But the chemical company was able to transfer the ammonia to another container without a chemical cloud forming.  Ammonia is hazardous, so crews took every precaution.
