Federal And State Records Show Longview Mill Ignored Warnings Amid Years Of Safety And Chemical Violations
A tank at Nippon Dynawave's Longview pulp mill catastrophically failed on May 26, 2026, killing 11 workers and releasing caustic liquid while state inspectors were scheduled to interview employees that week.[1]
Federal investigators found the vessel had been labeled unfit for service about 10 months before the collapse.[2] Washington's Department of Ecology issued 54 environmental violation notices to the plant since 2016.[1] The Department of Labor and Industries investigated more than a dozen safety complaints since 2018 and levied nearly $7,000 in fines.[1] Labor and Industries also reports more than $2.4 million in workers' compensation claims paid for 169 injured plant employees since 2015, including injuries from caustic exposure.[1]
Records show major prior releases and equipment failures at the site.[1] In 2020, about 250,000 gallons of black liquor spilled from a storage tank and contaminated gravel inside and outside the containment area.[1] In August 2021, roughly 3,000 gallons of white liquor leaked from an open valve and reached a storm drain, and investigators cited a 2023 conveyor-belt fire and chlorine releases in 2021, 2024 and 2025 tied to equipment failure.[1]
A March 2026 employee complaint said a detached valve handle on an ammonia clarifier tank prevented closure and risked toxic air releases and a possible explosion.[1] An inspector who planned to visit the plant on May 26 later cited the company and in August fined it $2,890 for failing to inspect and maintain pipes, hoses and valves and to keep inspection records.[1] A wrongful-death lawsuit filed by the mother of two victims alleges failures to maintain and inspect equipment, train and supervise employees, and implement safety and emergency-response procedures, and a chemical engineering professor called the pattern of spills, violations and the collapse a red flag that the site "has not been maintained."

The mainstream summary frames the Longview mill disaster primarily as a tragic failure of safety protocols, but it does not delve into the broader implications of systemic issues in industrial safety highlighted by various commentators. For instance, @ScalpingX emphasizes that the incident reflects significant risks stemming from corrosion and maintenance deficiencies in facilities managing hazardous chemicals, suggesting that the problem may extend beyond the specific failures at Nippon Dynawave to a more pervasive industry-wide concern about safety practices. Furthermore, while the summary mentions the tank's unfit status, it omits the context provided by @BostonGlobe, which categorizes this event as one of the deadliest workplace disasters in recent U.S. history, underscoring the severity and potential for similar occurrences in the future if systemic issues are not addressed.
Additionally, the mainstream account does not mention the ongoing investigation by the U.S. Chemical Safety Board, as noted by @chemsafetyboard, which could yield further insights into the conditions leading up to the catastrophic failure. This investigation is seen as a critical step towards understanding the multifaceted factors contributing to the disaster, which the summary does not fully explore, leaving readers without a comprehensive view of the implications for industrial safety regulations and practices.

- The EPA's National Response Center recorded eight methyl mercaptan releases from the Longview plant between 2017 and 2023, including a September 2017 incident that hospitalized a private citizen; residents repeatedly filed odor complaints and Ecology fined the company $4,500 in 2024 for excessive sulfur dioxide emissions (EPA's National Response Center).
- Records show a 2020 active release of about 250,000 gallons of black liquor that spilled inside and outside containment and contaminated gravel, an August 2021 release of roughly 3,000 gallons of white liquor that reached a storm drain, plus other equipment-related incidents including a 2023 conveyor-belt fire and chlorine releases in 2021, 2024 and 2025 attributed to equipment failure (250,000 gallons of black liquor).
- A wrongful-death lawsuit filed by Sheri Lynn King, mother of two brothers killed in the May 26, 2026 collapse, alleges failures to maintain and inspect equipment, train and supervise employees, and implement safety and emergency-response procedures; chemical engineering professor Stephen Kmiotek described the pattern of spills, violations and the fatal collapse as evidence the site 'has not been maintained' and a red flag for risks to employees and the public (Sheri Lynn King).
