This property has a documented history as a gasoline service station going back to 1929. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
This property operated as a Mobil service station from 1929 — with a lease recorded as early as June 1927 documenting fifteen 65-gallon oil tanks and three gas pumps on site — and continued in service through multiple decades under an ExxonMobil predecessor. The release of total petroleum hydrocarbons (gasoline, diesel, and motor oil fractions) and lead in soil and groundwater is linked to those historical service station operations. A site investigation begun in 2016 included a limited excavation for GPR anomaly investigation and ongoing management of petroleum-impacted soil, purge water, and decontamination water in 55-gallon drums; further contaminant delineation has been recommended and no active remediation has yet commenced. 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.
Petroleum contamination and lead at this site trace directly to service station operations that began in 1929, more than five decades before 1986, when occurrence-based CGL policies were the industry standard and carried no effective pollution exclusion in Washington. The detection of lead in soil and groundwater independently confirms the pre-1986 operational origin, as leaded gasoline was phased out before that year. With site investigation ongoing and full remediation yet to begin, the delineation, cleanup design, and eventual remediation costs ahead represent expenditures that historical carriers whose policies were in effect during those decades of fuel dispensing may be obligated to fund.
Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.
