LONGVIEW, Wash. — A massive chemical tank holding nearly a million gallons of a highly corrosive liquid imploded and collapsed Tuesday at a Washington paper mill, killing at least one worker and leaving nine others unaccounted for with no hope for rescue, authorities said.
Another nine people were injured, some severely, in the spill at Nippon Dynawave Packaging Co. in Longview. The cause remained unclear.
“At the moment we are not aware of any rescues that are yet to be made,” Cowlitz Fire and Rescue Chief Scott Goldstein said during a Tuesday evening news conference in which officials repeatedly referred to the situation as a recovery effort.
That effort would not resume until Wednesday morning, when emergency responders planned to work on stabilizing the collapsed tank, which still had about 90,000 gallons (more than 340,000 liters) of a chemical brew known as “white liquor” inside, and then search for the missing, Goldstein said.
The severity of the injuries ranged from minor to critical, with some suffering burns or inhalation injuries, authorities said. Among those injured was a responding firefighter.
Officials said they would only work during daylight hours because there was a risk of the tank leaking more caustic liquid and potentially collapsing.
“We don’t know until we know, hopefully tomorrow, how we can stabilize the tank. Do we remove the product first? Do we stabilize the tank first or the vice versa?” Goldstein said.
Authorities said there was no threat to the public.
Community waits for more information
At a community vigil Tuesday night, dozens gathered at a local park to pray, light candles and embrace teary-eyed loved ones.
Crystal Moldenhauer, a Longview resident who served on the school board, said she has friends who work at the plant and remained unaccounted for. She described the stress of the day as people called and texted each other trying to figure out what happened.
“We’re all still waiting for answers,” she said. “There’s families that have been torn apart, and we don’t know why.”
Two upset parents who said their two sons worked at the plant interjected at the end of the news conference, saying they hadn’t been contacted. While officials including Gov. Bob Ferguson, U.S. Sen. Patty Murray and U.S. Rep. Marie Gluesenkamp Perez addressed those gathered, no one from the company spoke at the news conference.
Some people waited at the company’s visitor entrance earlier Tuesday, seeking information about loved ones. They declined to comment to an Associated Press reporter. At a nearby union hall that was serving as a family assistance center, three women shared a tearful embrace before heading inside. Others coming and going were also in tears.
Facility is central to the community
The Nippon Dynawave Packaging Co. facility is a pulp and paper mill and liquid packaging plant along the Columbia River in Longview, a city of about 38,000 that has had a relationship with the paper and lumber industries since its founding by a Kansas City timber baron in the 1920s.
The facility, which employs about 1,000 people and dates to 1953, makes material for tissues, printing paper, cups, plates, cartons and other goods. It is located in an industrial zone shared by other timber, paper and chemical businesses, and it remains central to the community.
“The people who are responders here have friends and relatives that work on site,” Cowlitz Fire and Rescue Chief Scott Goldstein noted. “It is something that is impactful, and we have support networks to support the workers as well as the emergency responders.”
Officials initially reported that the tank had a capacity of 80,000 gallons (303,000 liters), but later revised that number to say it was holding about 900,000 gallons (3.4 million liters) of the “white liquor.” That’s nearly enough to fill a typical Olympic-sized swimming pool one and a half times. The liquid, which consists mainly of sodium hydroxide and sodium sulfide, is used with heat to break down wood to make kraft paper, a durable material used in packaging, shopping bags and other products.
Cause is not yet known
It was too early to determine the cause of the implosion, Goldstein said.
Following the tank’s rupture, the white liquor spilled into a drainage ditch, said Brittny Goodsell, a state Ecology Department spokesperson. The department sent a team to evaluate the impacts, Goodsell said.
“I know there’s a lot of questions about how all of this happened and I want to assure you that we will all continue to pressure to get answers to those questions,” Murray said during the Tuesday evening news conference. “This community deserves that.”
The implosion came as thousands of residents of Southern California remained evacuated Tuesday due to a damaged chemical tank at an aerospace plant. All evacuation orders were lifted Tuesday night.
Just over 40 people died between January 2021 and mid-October 2023 as a result of hazardous chemical incidents, according to a paper released by a network of environmental justice organizations in late 2023.
Previous health and safety violations
Safety complaints were filed against Nippon Dynawave on March 4 and May 6. The state’s labor and industries department said on X that both are unrelated to the current situation and remain open. The former was an anonymous complaint about a valve on an aqua ammonia clarifier tank, according to the department, which noted that “it was not the tank that imploded.” The other was opened about a sinkhole created by a drain that failed, according to the department.
Nippon Dynawave, a subsidiary of Japan-based Nippon Paper Group, has been fined a total of $3,400 for three separate health and safety violations found by Washington Department of Labor and Industries inspectors since the start of 2021, according to the department’s online database.
In one inspection, the company was cited because face coverings were not worn by every employee when required. In another, the inspector determined that an employee was exposed to the risk of falling while working on a platform more than 4 feet (1.2 meters) off the ground.
In the third incident, the department determined that equipment involved in a work-related accident – an amputated finger – was moved from its original position before the state’s investigation into the accident was complete.
