A structural failure of a chemical storage vessel at a paper mill has resulted in multiple fatalities, numerous missing persons, and localized environmental contamination.

一家造紙廠的化學儲存槽發生結構失效，導致多人死亡、多人失蹤以及局部環境污染。

The incident commenced on Tuesday at the Nippon Dynawave Packaging Co. facility, where the rupture of a tank led to the release of approximately 500,000 to 570,000 gallons of 'white liquor,' a highly corrosive agent utilized in wood pulp processing. This failure resulted in the confirmed death of two individuals, including an electrician identified as Gilbert Bernal, while nine additional personnel remain missing. Authorities have indicated that the probability of survivor recovery is negligible. Furthermore, eight individuals, including one emergency responder, sustained injuries characterized by chemical burns and respiratory inhalation.

該事故於週二發生在 Nippon Dynawave Packaging Co. 廠區，當時一個儲槽破裂，導致約 50 萬至 57 萬加侖的「白液」洩漏，這是一種用於木漿處理的高度腐蝕性藥劑。此次失效導致兩名人員確認死亡，其中包括一名身分確認為 Gilbert Bernal 的電工，另有九名人員仍然失蹤。當局表示，尋獲生還者的機率微乎其微。此外，包括一名緊急應變人員在內的八人受傷，傷情為化學灼傷及呼吸道吸入。

Environmental mitigation efforts are currently focused on the containment of the corrosive runoff. While the administration of Governor Bob Ferguson and local fire officials have confirmed that the Columbia River experienced a pH level spike and localized aquatic mortality—specifically involving carp—the U.S. Environmental Protection Agency has asserted that no significant systemic effect has been observed. Current remediation strategies involve the utilization of fire hydrants to dilute contaminated water within drainage ditches prior to its discharge into the river. Concurrently, atmospheric monitoring has yielded no evidence of airborne toxicity, and the municipal potable water supply remains uncontaminated.

環境緩解工作目前集中於控制腐蝕性逕流。雖然州長 Bob Ferguson 的政府及當地消防官員確認，哥倫比亞河的 pH 值出現飆升且導致局部水生生物死亡（特別是鯉魚），但美國環境保護署（EPA）則主張未觀察到顯著的系統性影響。目前的修復策略包括利用消防栓稀釋排水溝中的污染水，再將其排放至河中。同時，大氣監測未發現空氣毒性證據，且市政飲用水供應仍未受污染。

Institutional responses have been characterized by the Nippon Paper Group through the issuance of formal condolences to the affected families. The socio-economic impact is exacerbated by the facility's integration into a community with multi-generational ties to the lumber and paper industries. The precise causality of the vessel failure remains subject to an ongoing official investigation.

在機構回應方面，Nippon Paper Group 已向受影響家庭發出正式弔唁。由於該廠區與一個對木材及造紙業有數代情緣的社區緊密結合，使得社會經濟影響更加嚴重。儲槽失效的精確原因仍有待官方持續調查。

Recovery operations continue under hazardous conditions while environmental agencies monitor the dilution of chemical runoff in local waterways.

救援行動在危險條件下繼續進行，同時環境機構監測當地水路中化學逕流的稀釋情況。
