500 lbs Propane Tanks

Duluth, MN | 2012-Jun-23

Initial Notification: On June 23, 2012 at 1142(eastern), USCG MSU Duluth contacted the SSC. Recent flooding has caused at least three residential propane tanks containing up to 500 pounds or propane to break free from their connections and were spotted floating during overflights. Although the tanks should have emptied as soon as they broke free, MSU Duluth requested worst case scenario ALOHA air plume models to gauge the threat posed by the propane if it were still in the tanks. Local winds were reportedly SE at ~7 knots.
