WEAVERVILLE, Calif. -

A small fire caused about $8,000 in damage at the Trinity River Lumber Mill Monday night in Weaverville.

According to Weaverville Fire Department, the fire was contained to the debarker equipment area.  It involved saw dust and a section of the conveyor belt.  

A total of 28 firefighters responded from Weaverville Fire, Douglas City Fire, Lewiston Fire and CAL FIRE.  

Firefighters determined the fire was caused by a residual spark from welding work that was done earlier in the day.  The area had been checked several times after work was complete.

The fire was discovered by a security guard patrolling the grounds.  An off-duty mill employee driving by stopped and used a garden hose to keep the fire in check until firefighters arrived.  

This same mill burned down in a fire sparked by a welder's torch in 2009.  Approximately 140 employees lost their jobs until the mill was rebuilt.

The $20 million complex was rebuilt a year later.
