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 retail fuel station in central Montesano, part of a corridor of gasoline stations along and near Pioneer Avenue that dispensed fuel through single-walled steel underground storage tanks for decades before many closed following a highway relocation in the late 1960s. Leaking USTs were discovered in the late 1980s during sewer system replacement, triggering a multi-year investigation and cleanup under the Voluntary Cleanup Program that ran from at least 2004 through 2009. Remediation included the excavation and removal of multiple underground storage tanks and approximately 377 tons of contaminated soil, groundwater treatment through monitoring-well purge-water collection, and vacuum extraction. The site has reached No Further Action status with institutional controls — restrictive covenants and periodic site reviews — in place. 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 property originated from underground storage tanks that were in service well before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The documented cleanup expenditures — tank removals, excavation of hundreds of tons of soil, groundwater treatment, and years of investigation — are the kind of remediation costs those historical policies were written to cover. Carriers who issued CGL policies to the operators during the decades these tanks were leaking may still be obligated to reimburse those costs.
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.
