Portland Fire & Rescue investigators released the cause of this morning's fire that destroyed four semi-trucks on Swan Island.  A mechanical/electrical malfunction caused the fire which completely destroyed four trucks and severely damaged four 50' trailers.  Damage is estimated at $1 million dollars.

Firefighters were called to N. Channel Avenue at about 3:15 am on Wednesday, November 25, 2009.  Firefighters arrived on-scene and reported heavy fire and smoke from a fenced and secured area. After cutting the chain on one of the gates, firefighters were able to extinguish the fire in a matter of minutes.

Concerns were raised about runoff from the fire flowing into the Willamette River.  A fireboat was dispatched to check the outflows in the area and found no evidence of contamination in the river.
