BOULDER COUNTY, Colo. — The abandoned Old Sugar Mill factory near Longmont caught fire just after midnight Tuesday, according to the Boulder County Sheriff's Office.
Due to hazardous materials and weather conditions, the Boulder County Sheriff's Office said firefighters would not actively fight the fire. Instead, they let it burn throughout the night.
The sheriff's office and Longmont Fire Department said early Tuesday that they would stay on scene to monitor the fire. The blaze was controlled and contained by about 12:30 p.m.
There was no danger to the public, the Boulder County Sheriff's Office said. It told neighbors to remain outside the area controlled by Longmont FD and the Boulder County Sheriffs' Office.
The cause of the fire is under investigation.
This property has seen three fires since 2017, the most recent was last August. Firefighters took the same approach to that fire, letting it burn for more than 24 hours.
