This property has a documented history as a gasoline service station predating 1986. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This property operated as a fueling facility with underground storage tanks at 3800 NE 4th Street in Renton. Releases of TPH gasoline, diesel, oil, and BTEX were identified in both soil and groundwater, placing the site on Ecology's Leaking Underground Storage Tank (LUST) List and the Confirmed and Suspected Contaminated Sites List. Cleanup under the Voluntary Cleanup Program included soil remediation — receiving an interim No Further Action determination for soils in 2001 — followed by ongoing groundwater monitoring through at least 2003, culminating in a final No Further Action determination in 2007 and removal from both lists. 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 petroleum contamination at this site — gasoline, diesel, oil, and BTEX from leaking underground storage tanks — is the signature of fueling operations that predate the modern UST regulatory framework of the late 1980s. Occurrence-based Commercial General Liability policies issued during that earlier operational window carried no effective pollution exclusion in Washington and remain enforceable today. Six years of documented remediation costs under the Voluntary Cleanup Program, from soil cleanup through long-term groundwater monitoring to final closure, represent expenditures that historical carriers who covered those pre-1986 operations may still be obligated to reimburse.
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.
