This property has a documented history as a gasoline service station going back to 1945. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property operated as a Shell-branded gasoline service station from approximately 1945 until 1991, with facilities that included two dispenser islands and four underground storage tanks ranging from 4,000 to 8,000 gallons for unleaded, regular, and supreme gasoline. Cleanup under the Voluntary Cleanup Program has included UST excavation and removal, monitoring well decommissioning, and ongoing multi-year groundwater monitoring and sampling. Remediation work at the site is ongoing. 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 at this property originated from underground storage tanks that were installed and operated for more than four decades before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion in Washington. The documented remediation expenditures — tank excavation, well decommissioning, groundwater monitoring, and waste disposal — trace directly to releases from those pre-1986 operations. Historical carriers who issued CGL policies during the station's 1945-to-1986 operating window may be obligated both to recover past cleanup costs and to fund the remediation still underway.
