This property has a documented history as a industrial and manufacturing facility going back to 1941. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property operated as a plywood mill from 1941 to 2011, with a petroleum pipeline (Pipeline 8) in service from 1941 to 1967. Hydraulic oil from the mill's presses and pentachlorophenol contaminated the vadose zone and groundwater over decades of operation, forming a persistent smear zone of historically pooled contamination. The current cleanup plan calls for excavating 17,200 cubic yards of impacted soil, in-situ chemical oxidation or oxygen release compound treatment of groundwater, and long-term monitoring projected to span five to ten years, along with an environmental covenant to manage residual contamination. 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.
The smear zone and historically pooled contamination documented at K Ply are the product of chronic releases during 45 years of pre-1986 mill operations — hydraulic oil from presses and gasoline from Pipeline 8, which ran from 1941 until 1967. That pattern of gradual, accumulating release across decades is precisely what occurrence-based CGL policies were designed to cover, and Washington carriers issued those policies to industrial operators throughout K Ply's operational window. The remediation now underway — 17,200 cubic yards of soil excavation, in-situ groundwater treatment, and up to a decade of monitoring — represents costs that historical carriers whose policies were in force during those chronic-release years may be obligated both to recover and to fund going forward.
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.
