This property has a documented history as a property with a heating oil tank going back to 1958. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This residential property was built in 1958 with an original 500-gallon heating oil underground storage tank installed at that time. A release from the UST resulted in petroleum-diesel range hydrocarbons (TPH-D) detected in groundwater above MTCA Method A cleanup levels in on-property monitoring wells, with contaminated groundwater having migrated to a nearby creek via a subsurface culvert. The original tank was removed in November 2004 and replacement tanks were subsequently installed; the site entered the Voluntary Cleanup Program and received a No Further Action determination in 2022. 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 release at this property originated from an underground storage tank installed in 1958 — nearly three decades before the 1986 shift away from occurrence-based Commercial General Liability policies. CGL policies issued to the property owner during those decades of UST operation carried no effective pollution exclusion under Washington law and remain enforceable today. The documented remediation costs — tank removal, groundwater investigation, and the multi-year path to a No Further Action determination — represent expenditures that historical carriers 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.
