LONGVIEW — The Washington State Department of Labor & Industries opened inspections at two kraft paper mills and launched a statewide enforcement effort to inspect chemical use and storage at all non-kraft paper mills on a Thursday. These actions follow a tank failure at Nippon Dynawave in Longview that killed 11 workers.

One of the kraft mills is operated by Smurfit Westrock in Longview, and the other by Port Townsend Paper Company in Port Townsend. Both facilities use the kraft pulping process, which involves caustic chemicals, including white liquor, to break down wood into paper pulp. The new inspections at these facilities are distinct from the agency's ongoing investigation into the Nippon Dynawave incident.

Inspectors will examine tank maintenance and testing records, open repair items, and reports of spills and breaches. They will also review operating and maintenance procedures, alongside records detailing any injuries or near misses involving workers around the tanks. The inspections at the kraft paper mills could extend for up to six months, and the agency stated that findings will be released upon completion of the work.

L&I Director Joel Sacks said the inspections are intended as a precaution. Sacks said, "These investigations and our targeted enforcement program are precautionary, proactive steps for worker safety at Washington's paper mills." Governor Bob Ferguson said, "Keeping workers safe at work is our top priority." Ferguson added, "We continue to grieve with the families and loved ones of those killed in the deadliest industrial tragedy in modern Washington state history." He also said, "My team is proactively working to ensure employers are identifying and addressing any potential risks that exist at similar sites."

The statewide enforcement effort targets Washington's seven non-kraft paper mills, focusing on their chemical use and storage. These inspections are projected to continue through February 2027. State law mandates that employers identify workplace hazards, including those related to chemical storage tanks, and implement measures to address them. If inspectors identify safety violations, the department may issue citations and fines. Employers have a 15-working-day period to file an appeal after receiving any citations.
