More than 11,000 gallons of liquid fertilizer was accidentally released in Richland County according to the North Dakota Dept. of Environmental Quality.

The spill was detected by Minn-Kota Ag Products on Tuesday after the leak happened in an above-ground storage tank. It was caused by a small rust hole in the tank, which was located about a mile west of Colfax.

The site is being inspected by state officials who will monitor the investigation.
