This property has a documented history as a property with a heating oil tank predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
The Park Ridge Care Facility operated with at least two underground storage tanks — a former gasoline UST and a former home heating oil UST — on a property that also encompasses a former dry cleaning area. The USTs were closed under a formal closure and subsurface assessment in 2002, at which time interceptor trenches were installed; since then, the site has undergone multi-year enhanced bioremediation using repeated injections of Oxygen Release Compound and calcium peroxide/persulfate into those trenches. Groundwater monitoring and reporting to Ecology have continued since closure, and the site remains in active cleanup under the Voluntary Cleanup Program. 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.
Lead contamination documented in both soil and groundwater at this property is a definitive indicator of operations during the leaded gasoline era — confirming that the USTs here were active well before 1986, the threshold year for occurrence-based CGL policies that carried no effective pollution exclusion. The remediation expenditures incurred to date — formal UST closure, trench installation, multiple rounds of in-situ bioremediation, and sustained groundwater monitoring — are directly traceable to releases from those pre-1986 operations. Historical carriers who issued CGL policies to the care facility or earlier operators during that window may be obligated to fund both the costs already incurred and the cleanup work still underway.
