This property has a documented history as a property with a heating oil tank going back to 1943. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
The South Kitsap School District Administration Building was constructed in 1943 and heated by an underground oil-burning furnace system for decades. The historic 675-gallon heating oil UST and its associated piping were discovered in 2012 and removed in 2013 under the Voluntary Cleanup Program, along with 17.69 tons of petroleum-contaminated soil. Residual contaminated soil that could not be excavated is managed in place under a physical barrier and institutional controls, with groundwater monitoring required every five years under an Environmental Covenant; 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.
The heating oil system at this property was installed and in continuous operation from at least 1943 — more than four decades before pollution exclusions became standard in Commercial General Liability policies. Releases from a system of that age fall squarely within the coverage period of occurrence-based CGL policies that carried no effective pollution bar. The documented remediation costs here — UST removal, soil excavation, physical containment of residual soil, and a perpetual five-year groundwater monitoring obligation — were incurred to address contamination tied directly to those pre-1986 heating operations, and historical carriers whose policies were in force during that operational window may remain obligated to fund them.
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.
