This property has a documented history as a property with a heating oil tank going back to 1929. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
The Luther Burbank Park property was historically operated as a residential and juvenile correctional agriculture school, with a boiler plant in service as early as 1929 that stored diesel and bunker-type heating oil in underground storage tanks. A leak observed in 1983 prompted the initial UST decommissioning, establishing a pre-1986 contamination origin; investigations beginning in 2002 have consistently traced the soil and groundwater impacts to those historical tank releases. Active remediation under the Voluntary Cleanup Program encompasses soil excavation, chemical treatment of residual soil and groundwater, monitored natural attenuation, hardscape engineered controls, and institutional controls supported by a multi-year monitoring and management framework. 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 diesel and heating oil releases at this site originated from underground storage tanks that operated for more than five decades before their 1983 decommissioning — a liability window falling squarely within the era when occurrence-based Commercial General Liability policies were standard and pollution exclusions were not yet effective. The 2002-onward remediation record consistently attributes contamination to those historical UST releases, not to any subsequent event, establishing a direct causal chain to pre-1986 policy periods. Historical carriers who issued CGL coverage to the school or its operators during that operational window may bear an obligation to fund the ongoing excavation, treatment, and long-term monitoring costs this cleanup demands.
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.
