Industrial & Manufacturing cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1928. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

This Tacoma industrial property has housed a pulp and paper mill since 1928, with operations under various owners predating the existence of environmental regulations. The site was operated by Simpson Tacoma Kraft Company, LLC until 2014, during which time Kraft pulping processes generated significant contamination — including a 100,000-gallon black liquor spill in November 1996 — alongside industrial chemical use involving sulfuric acid. Dioxin and furan contamination has been identified at the site; WestRock, the current property owner, plans to remove wood waste as an initial step, with full remediation of dioxin/furan contamination anticipated to span 5 to 10 years, followed by long-term operation and monitoring phases. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.

Why Historical Insurance Policies May Be Accessible

Pre-1986 Commercial General Liability (CGL) policies were occurrence-based and did not contain an effective pollution exclusion in Washington. If contamination occurred while those policies were active, those historical insurance carriers may still have a legal obligation to fund the cleanup costs, even if the business closed or the property changed hands.

Pulp and paper manufacturing at this site began in 1928 and continued for decades under occurrence-based Commercial General Liability policies that predate the effective pollution exclusions introduced after 1986. The dioxin and furan contamination now driving remediation is the direct byproduct of Kraft pulping operations conducted throughout that pre-1986 window — precisely the category of gradual industrial release those policies were written to address. With a documented remediation horizon of 5 to 10 years and long-term monitoring to follow, the total cleanup liability here is substantial, and historical carriers who issued CGL policies during the mill's pre-1986 operational decades may bear an obligation to fund those costs.

Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.

The Restorical Proven Process

Task 1 — Research and Analysis
Restorical searches for viable historical insurance policies, researches the site history, analyzes the contamination impacts, and underwrites potential coverage — including a proprietary trigger analysis. At the end of Task 1, we provide a clear yes or no on whether a successful cost recovery is possible, along with a strategy and recommendation specific to your situation, even if you are not the policyholder.
Task 2 — Coverage and Funding
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim, negotiate and secure insurance coverage. Restorical will manage the ongoing claim process, including accounting to ensure the insurance companies are funding your remediation in a timely manner.
