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.
This Bainbridge Island property experienced a petroleum release from a heating oil underground storage tank that contaminated both soil and groundwater. Remediation under the Voluntary Cleanup Program included excavation of contaminated soil, formal decommissioning of the UST — documented in a June 2006 Heating Oil Underground Storage Tank Decommissioning Report — and subsequent groundwater monitoring over a minimum of two years to confirm that cleanup standards had been met. The site has 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.
Applying the standard tank lifecycle analysis, a heating oil UST decommissioned in 2006 was typically installed roughly 25 years earlier, placing this tank in service by approximately 1981 or earlier — squarely within the era when occurrence-based CGL policies were still issued without effective pollution exclusions. The contamination here arose from a gradual operational release during that pre-1986 window, precisely the scenario those policies were written to address. The documented remediation expenditures — soil excavation, tank decommissioning, and multi-year groundwater monitoring — represent costs that historical carriers may still be obligated to recover.
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.
