Video reveals catastrophic tank rupture and deadly chemical spill at Longview pulp mill

A public-records video shows the Nippon Dynawave wood-pulp mill in Longview rupturing a tank and releasing hundreds of thousands of gallons of white liquor, killing 11 workers as spills spread into parking areas and ditches; rescue efforts were delayed, autopsies cite severe chemical burns as a factor in all deaths, and multiple agencies are investigating while the plant remains out of service and plans temporary storage tanks to restart.
