LONGVIEW, Washington (From news reports) -- The widow of an electrician who died in the May 26 spill at the Nippon pulp and paper mill in Longview is suing the company in Cowlitz County Superior Court.

Jared Ammons went to work early on the day of the spill because his wife had a later ultrasound appointment and he wanted to leave early to be there, the suit states.

But Jared Ammons never made it to the appointment.

Mackenzie Ammons, his widow and personal representative, filed the suit earlier this month on behalf of herself and her children. She is represented by the Seattle-based law firm of Osborn Machler & Neff.

An exact dollar amount for relief is not listed in the suit.

The eight-page document states a Marietta, Georgia, company contracted by Nippon Dynawave Packaging called Applied Technical Services, LLC inspected the tank that failed three times before the spill: in July of 2025, October of 2025, and February.

The board reports that an inspection of the tank's exterior carbon-steel shell at that time showed parts had thinned below what is considered a safe thickness.

The U.S. Chemical Safety Board included this information in an August preliminary report about the spill that released an estimated 900,000 gallons of heated, caustic chemicals used in paper making.

Applied Technical Services told Nippon staff the tank was "not fit for continued service" and that unless the tank was repaired, there was a "high likelihood of failure," according to the board's findings and cited in the lawsuit.

After each inspection of the 1.2-million-gallon tank, Applied Technical Services reportedly told Nippon that the tank's carbon steel walls were severely corroded due to the white liquor and that the walls had become thinner.

Three months after the company last informed Nippon staff, the tank failed, killing 11 workers, including Jared Ammons.

He reported to the electrical maintenance shop at Nippon, which sits across the courtyard from the white liquor tank, the suit states. The chemical mix is maintained at around 200 degrees.

When the tank spilled at 7:09 a.m., Jared Ammons and seven other workers were in the electronic maintenance shop for a morning meeting, the suit continues. The white liquor spilled across the courtyard and broke through the walls, doors and windows of the shop, trapping everyone inside.

Two other workers in the shop and another in the courtyard were killed. The suit states two other employees suffered chemical burns.

A summons was filed for the pulp and paper mill on Sept. 9, according to court records.

The mother of two workers, Bradley Kyle Covington and Tyler Scott Covington, filed her own wrongful death lawsuit against the company in August.

Sheri Lynn King's lawsuit states that the Castle Rock brothers had just arrived in the Nippon parking lot when the tank collapsed.
