Incident Overview
On the morning of May 26, 2026, a chemical storage tank at the Nippon Dynawave Packaging Co. pulp and paper mill in Longview, Washington, ruptured and collapsed. Reported at approximately 7:15 a.m. local time, the event left one confirmed fatality, nine workers listed as missing, and nine additional injuries—including a firefighter. Emergency responders described the scene as a “mass casualty” incident.
Timeline
- 7:15 a.m. – Tank implodes; fire crews, haz-mat teams, and EMS arrive.
- 7:30 a.m.–8:00 a.m. – Patients decontaminated and transported to hospitals in Longview and Vancouver.
- Evening – Officials announce a recovery phase; operations suspended due to tank instability.
- Next morning – Stabilization work scheduled to resume; additional agencies deployed.
Facility Background
Nippon Dynawave Packaging Co., a subsidiary of Japan-based Nippon Paper Group, operates a kraft pulp mill and liquid-packaging plant on the Columbia River. Established in 1953, the complex employs roughly 1,000 workers and supplies tissue, printing paper, cartons, cups, and plates to markets across North America. The mill is a longstanding economic anchor for the city of Longview (?38,000 residents).
Data & Statistics
- Casualties: 1 death, 9 missing, 9 injured (including 1 firefighter).
- Responder count: ~40 firefighters, paramedics, and a regional haz-mat team.
- Tank size: Initial reports cited an 80,000-gallon tank about 60 % full; later assessments indicated a capacity near 900,000 gallons with roughly 90,000 gallons remaining.
- Chemical: “White liquor,” a caustic mixture of sodium hydroxide, sodium sulfide, and disodium carbonate used in kraft pulping.
Official Statements & Responses
Washington Governor Bob Ferguson expressed condolences and ordered state agencies—including the Department of Ecology and the National Guard’s civil-support team—to assist. U.S. Senator Patty Murray called the incident an “absolute tragedy” and urged a thorough investigation. Senator Maria Cantwell thanked first responders and pledged federal resources. Chief Scott Goldstein of Cowlitz Fire and Rescue emphasized life-safety concerns and confirmed no immediate public health threat. Battalion Chief Mike Gorsuch of the Longview Fire Department labeled the event a “mass casualty scene.”
Criticism & Opposition
State labor inspectors have previously cited Nippon Dynawave for three health-safety violations since 2021, resulting in $3,400 in fines for issues such as inadequate face-coverings, missing fall protection, and mishandling of equipment after a work-related accident. Separate safety complaints filed on March 4 and May 6 remain open and unrelated to the current incident, fueling community concerns about the plant’s safety culture.
Conflicting Reports & Gaps
- Tank capacity: Early coverage listed an 80,000-gallon vessel; subsequent statements revised the figure to roughly 900,000 gallons.
- Cause: Officials have not identified a definitive cause, citing possibilities ranging from mechanical failure to pressure buildup.
- Fatalities: The exact number of deaths remains undisclosed; authorities have withheld the count of missing persons pending family notification.
Why It Matters
The mill’s disruption threatens the livelihoods of a sizable portion of Longview’s workforce and reverberates through regional supply chains. Residual white liquor poses environmental risks to nearby ditches and the Columbia River; state Ecology teams are monitoring pH levels. The incident underscores broader industrial-safety challenges in the Pacific Northwest, especially at facilities handling highly corrosive chemicals.
