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 private residential property at 4727 9th Avenue NE housed a 300-gallon underground heating oil tank that developed corrosion holes, releasing heating oil into the surrounding soil and groundwater over time. Remediation under the Voluntary Cleanup Program ran from 2004 to 2009 and included excavation and removal of the tank along with 90 tons of contaminated soil, followed by in-situ groundwater treatment using Oxygen Release Compound, microbial injections, nutrients, and hydrogen peroxide. Multi-year monitoring accompanied the active remediation phases, and the site has since 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.
A corroding underground tank releasing heating oil gradually over years is precisely the kind of slow, cumulative contamination event that occurrence-based Commercial General Liability policies issued before 1986 were written to cover — and for which those policies carried no effective pollution exclusion. The corrosion-driven release documented here indicates the tank had been in service for a significant period before its 2004 removal, making pre-1986 operational years plausible. The documented remediation costs — tank removal, 90 tons of soil excavation, in-situ groundwater treatment, and multi-year monitoring — represent expenditures that historical carriers may still be obligated to fund.
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.
