This property operated as Exxon Station No. 7-3465, with Exxon Corporation's ownership documented in county records back to at least 1982. Four underground storage tanks were registered with the placeholder date of January 1, 1986 — the date federal UST regulations took effect — indicating the tanks predated that regulatory milestone. Petroleum releases from UST operations during Exxon's ownership were confirmed, with diesel-range and other petroleum hydrocarbons detected in groundwater. The site was addressed through the Voluntary Cleanup Program and 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.
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.
Exxon's documented ownership of this gas station extends to at least 1982, with underground storage tanks that predated the 1986 federal registration requirement — squarely within the era when occurrence-based Commercial General Liability policies were standard and carried no effective pollution exclusion. The petroleum releases from those pre-1986 UST operations generated cleanup obligations that were ultimately resolved through the Voluntary Cleanup Program. Historical CGL carriers who covered the station during that pre-1986 operational window may remain obligated to reimburse the remediation costs incurred to reach the site's No Further Action status.
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.
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.
