FEDERAL WAY-- Several lanes of southbound I-5 were closed for hours Sunday morning after a fatal crash involving a tanker truck and two cars.
A double tanker truck owned by Lee & Eastes Tank Lines was fully loaded with 9,000 gallons of gasoline when it crashed, caught fire and punctured a freeway sound wall at 2 a.m. Sunday.
The truck driver was killed.
Five people in the cars had minor injuries, one was taken to St. Frances Medical Center in Federal Way.
The fire on I-5 was so intense, a foam truck from Boeing Field had to be called in to help control the flames.
Washington State Patrol, WSDOT crews and nearly a dozen emergency response vehicles were on the scene after the crash, putting out the fire, closing lanes, managing traffic, checking the road surface and checking the sound walls.
As many as nine sound walls were damaged, the DOT said.
The Department of Ecology said both fuel tanks burst and released aviation gasoline, which continued to burn for hours.
Firefighters were conducting a controlled burn of the remaining fuel that spilled, including applying foam to flare-ups and hot spots when necessary.
DOE said on-site monitoring had not found any immediate health or safety concerns to nearby homes and businesses.
The DOE said all oil spills cause environmental damage, regardless of size. A single quart of oil has the potential to foul more than 100,000 gallons of water.
The State Patrol is investigating to determine the cause of the crash.
