Washington State Chemical Tank Failure

Authorities have confirmed that one person died and 9 others remain unaccounted for after a chemical tank imploded at a pulp and paper mill in Washington state. They say there is no hope to rescue those missing. Nine others were injured in Tuesday morning's spill, some severely. Emergency responders plan to resume recovery efforts at Nippon Dynawave Packaging Co. in Longview on Wednesday morning. Authorities say those efforts are being hampered by the danger posed by 90,000 gallons of the dangerous liquid that remain in the unstable tank.
