This property has a documented history as a property with a heating oil tank going back to 1960. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This Mercer Island property operated as a private residence from the early 1960s, with two 600-gallon underground storage tanks supplying heating oil to the original structure. A leak from one of those tanks was discovered in 2003 during tank removal, at which point soil contamination from petroleum hydrocarbons was confirmed. Cleanup consisted of excavating the contaminated soil and removing both tanks; post-excavation sampling confirmed the complete absence of petroleum hydrocarbons, 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.
The heating oil tanks at this residence were installed and in active service by the early 1960s — more than two decades before 1986, when occurrence-based Commercial General Liability policies were standard and carried no effective pollution exclusion. Although the leak was not discovered until 2003, the contamination itself was a product of those pre-1986 tank operations, not a recent incident. Historical carriers whose CGL policies were in force during the decades those tanks were in service may be obligated to fund the excavation and remediation costs that ultimately brought the site to its No Further Action resolution.
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.
