This property has a documented history as a public works and maintenance facility going back to 1970. Historical insurance policies issued during operations at this property and through 1986 could recover the cleanup costs already paid.
This property served as a maintenance and fueling area for the Sudden Valley Resort, developed sometime during the 1970s with underground storage tanks supporting equipment operations and community infrastructure. Four USTs were removed in 1992, and approximately 2,500 cubic yards of contaminated soil were excavated in 2000 and treated on-site through land farming and ex-situ biotreatment. Groundwater monitoring was conducted in two campaigns — quarterly sampling from 2000 to 2002 and again from 2017 to 2019 — alongside natural attenuation for soil and groundwater. The site has received a No Further Action determination 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.
Petroleum contamination at this property originated from fueling operations and underground storage tanks that were in place from the 1970s — more than a decade before 1986, when occurrence-based CGL policies still carried no effective pollution exclusion in Washington. The documented remediation expenditures — tank removal, excavation and treatment of 2,500 cubic yards of soil, monitoring well installation, and two separate multi-year groundwater monitoring campaigns — represent costs tied directly to releases from those pre-1986 operations. Historical carriers who issued CGL policies covering this facility during the 1970s and early 1980s may still be obligated to recover those cleanup 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.
