This property has a documented history as a property with a heating oil tank going back to 1941. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This property is a former single-family residence built in 1941, heated throughout its history by an underground petroleum storage tank. The tank was removed in 2005 under the Voluntary Cleanup Program, at which point petroleum-contaminated soil was discovered; approximately 64 tons of diesel-range hydrocarbon-impacted soil were excavated and disposed of off site. No groundwater was encountered during remediation, and the site has since achieved 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 heating oil tank at this residence was in service for decades before 1986, the period when occurrence-based Commercial General Liability policies covered pollution claims without effective exclusion. The diesel-range hydrocarbon contamination found in soil upon tank removal is consistent with a slow, long-running historical leak during that pre-1986 operational window. The remediation expenditures here — excavation and off-site disposal of 64 tons of impacted soil — represent costs that historical carriers whose CGL policies were in force while the tank was actively in use may 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.
