This property has a documented history as a property with a heating oil tank predating 1986. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
The Pfister Residence in Redmond was the site of a residential heating oil release, with petroleum hydrocarbons (heating oil/diesel) contaminating both soil and groundwater. Remediation under the Voluntary Cleanup Program included excavation of petroleum-contaminated soils, construction of an infiltration gallery for groundwater treatment, hydrogen peroxide addition in December 2002, and quarterly groundwater treatment events through 2003. Ecology subsequently determined that the release no longer poses a threat to human health or the environment, and the site received a No Further Action determination. 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.
Residential heating oil tanks installed and operated before 1986 fall squarely within the coverage window of occurrence-based insurance policies that carried no effective pollution exclusion — and the underground storage tank at this property was assessed in 2003 for a release consistent with decades of prior operation. The documented remediation costs here — soil excavation, groundwater treatment infrastructure, hydrogen peroxide injection, and multi-quarter monitoring — were incurred to address a release tied directly to that pre-1986 operational period. Historical carriers whose policies were in force when the contamination first occurred may still bear obligations to fund those cleanup expenditures.
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.
