MN, WATONWAN
Narrative
During local thunderstorms with extremely high winds, a tree toppled and landed on a district regulator station. Current district regulator station is the only feed for the small town (<250 customers). The force of the tree caused a flange on the inlet side to crack, resulting in a gas leak. The outlet piping also broke causing the downstream pressure side to release into atmosphere. The emergency valve for the station was turned off, resulting in all customers without gas until the repairs were made.
