Overview
- A storage tank holding more than 3.4 million liters of caustic soda burst, with the failure first reported on Tuesday and immediate hazardous‑materials operations launched.
- Emergency crews moved from rescue to recovery after concluding they did not expect survivors, and they recovered six of nine workers who had been reported missing.
- Authorities have confirmed eight deaths in the incident and continue careful recovery and victim decontamination before handover to the medical examiner.
- Sampling found elevated caustic concentrations in the Columbia River near the plant, but officials say there are so far no detected impacts to public drinking water or local air quality.
- State leaders have signaled a major probe into safety and regulatory lapses, and investigators are monitoring environmental effects and the human toll for families and nearby communities.
