Nine still missing after Washington paper mill tank implodes; daylight search resumes

Crews resumed searching for nine missing workers after a tank at Nippon Dynawave Packaging in Longview ruptured, releasing caustic white liquor; one person died and nine were injured. Because the tank risks further collapse, responders can only operate in daylight while they work to stabilize the structure and recover the missing. The plant sits along the Columbia River and had prior safety violations, but officials say there is no threat to the surrounding community as investigators pursue the cause.
