A leaking anhydrous ammonia tank, which forced the evacuation of Aurelia, Iowa, last Monday is now fixed.
Emergency crews capped the 30,000-gallon tank at the First Cooperative Association elevator.
At that point, the scene was rendered safe, and there were no injuries in the incident.
The incident started at 10 a.m. Monday when a faulty valve on the tank began leaking ammonia.
The evacuation of the town of about 1,000 people followed as the ammonia plume drifted north into downtown, and into residential neighborhoods.
The “all clear” was given at 5 p.m. allowing residents to return to their homes and businesses.
Even though the tank was still leaking at that time, the winds had shifted to carry the ammonia plume away from town.
