Chehalis

A three-alarm fire broke out Wednesday night at the Cascade Structural Laminators plant causing an estimated $15 million damage.

The blaze was extinguished Thursday, but on Thursday, Lewis County Fire District 6 Chief Bud Goodwillie said firefighters were still monitoring hot spots.

Known as the Chehalis Lam plant, it employed about 15 people.

Goodwillie says more than 50 firefighters from six departments responded.

There were no injuries. The cause of the fire is under investigation.

The state Ecology Department estimated that between 500 and 1,000 gallons of chemicals washed into nearby ditches and a creek with the water used to put out the fire.

The chemicals are used as a wood-products glue. An environmental-cleanup contractor was on the scene Thursday, and Ecology and state wildlife agents were checking for damage to water or wildlife.
