This property has a documented history as a industrial and manufacturing facility going back to 1890. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This property was occupied by the St. Paul & Tacoma Lumber Company from the late 1800s through 1992, with documented industrial infrastructure — an oil house, garage, and machine shop — present at the site as early as 1965. Oil-range and diesel-range petroleum hydrocarbons were identified in soil and groundwater, consistent with those long-term industrial operations. Remediation under the Voluntary Cleanup Program included site characterization and groundwater monitoring from 2011 to 2013, followed by containment through soil capping and the establishment of an Environmental Covenant as a permanent institutional control; a Disproportionate Cost Analysis was conducted to select the final remedy, and the site has reached No Further Action status. 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 petroleum hydrocarbons found in soil and groundwater here originated from an oil house, machine shop, and garage that were in active use for decades before 1986 — the period when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The St. Paul & Tacoma Lumber Company's century-long presence at this property creates a broad window of pre-1986 policy coverage potentially available to recover the remediation expenditures that followed: site investigation, multi-year groundwater monitoring, engineered soil capping, and the ongoing administrative burden of an Environmental Covenant.
Restorical's role is to locate viable historical policies, determine whether a successful cost recovery claim is possible, and assist our clients and their legal counsel to obtain insurance coverage for costs already incurred. Restorical's forensic accounting team works to re-establish and document past cleanup expenditures, ensuring the strongest possible basis for recovery.
Recovering Costs from an Older Cleanup
If this site reached No Further Action years ago, the original cleanup expenditures may be difficult to reconstruct. Restorical's forensic accounting team specializes in re-establishing and documenting past cleanup costs — even decades later — to build the strongest possible basis for an insurance recovery claim.
