Inspectors warned Washington paper mill of tank failure before deadly implosion

The operator of a paper mill that imploded in Washington, killing 11 people, had been warned twice that its facilities required significant repairs.

The U.S. Chemical Safety Board's update about the May 26 failure in Longview, which expelled enough caustic liquid to blow out building walls, is part of an ongoing investigation. The federal agency said it is still determining the cause of the failure.
