This property has a documented history as a automobile dealership predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
The former Mell's Chevrolet Olds dealership at this Shelton property operated a fueling facility, vehicle maintenance and service department, and paint and body shop, with three 1,000-gallon gasoline underground storage tanks that were abandoned in place in 1964. Petroleum contamination — including TPH, gasoline-range organics, diesel-range organics, and benzene — in soil and groundwater is attributable to those historical fueling and automotive service operations. Remediation under the Voluntary Cleanup Program has included UST removal, removal of residual hazardous liquids from hydraulic hoists, excavation and off-site disposal of approximately 348 tons of impacted soil, injection of in-situ biostimulation agents, and groundwater monitoring and sampling spanning at least 2010 through 2021. Cleanup work 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.
The three gasoline USTs abandoned at this property in 1964 place the contamination's origin more than two decades before 1986 — during the period when CGL policies issued to automotive dealerships routinely covered pollution claims arising from fueling and service operations. The documented remediation at Mell Chevrolet Olds — UST removal, nearly 350 tons of TPH-affected soil excavated and hauled off-site, biostimulation injections, and years of groundwater sampling — represents costs potentially attributable to the carriers who insured those pre-1986 operations. Because cleanup is still active, those historical carriers may be obligated not only to reimburse expenditures already incurred but to fund the remediation work that remains.
