Hibbing, MN (NNCNOW.com) --- The Hibbing Fire Department responded to a massive blaze at the Hibbing Public Utilities steam plant Saturday evening.
Initial reports of heavy smoke coming from the roof of the plant came in just before 9 PM.
The fire was located on the wood biomass side of the building, and took on more than one part of the plant. The plant is a large industrial building which houses one of the plant's boilers for steam generation.
One fire, on the main floor, was extinguished by PUC personnel, while multiple Iron Range fire agencies fought a separate fire on the roof of the seven story plant until just after 10:35pm.
Officials with the Hibbing Fire Department say the building sustained fire, smoke, and water damage estimated to cost $30,000.
Crews say, initially, there was a scare of an ammonia leak at the plant, but it turned out to be a small leak in the plant's urea tank.
There were no reported injuries in the incident. Investigators continue to search for the cause of the fire.
The fire required mutual aide response from neighboring fire and ems departments including: Chisholm Fire, Chisholm Ambulance, Keewatin Fire, Virginia Fire, Buhl Fire, Nashwauk Fire, Nashwauk Ambulance, Cherry Fire, Hibbing Police, and Hibbing public works.
