Just before 0400 hours, units were alerted to St. Mary's County for the Structure Fire on James Road. This brought Rescue Squad 10, Foam Tanker 10, and Chief 10B on the call. First arriving units from MVFD Co.2 found a saw mill on fire, with a building collapse, and fuel burning. Company 10 units arrived on scene and went to work assisting units with pulling out debris to aid in the extinguishment efforts. Foam Tanker 10 shuttled water to the scene from a water supply source in Wicomico Shores. Units worked for over 2 hours before being returned to service. No injuries were reported during this incident.
