This property has a documented history as a gasoline service station going back to 1964. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This commercial property has been in operation since 1964, with diesel-range petroleum hydrocarbons, motor oil, and free product discovered beneath the parking lot during redevelopment activities in 2016. Expert assessment in 2022 concluded the contamination had been present for at least 50 years, placing its origin no later than the early 1970s. Cleanup under the Voluntary Cleanup Program has included removal of 2,000 cubic yards of impacted soil, multi-phase and vacuum extraction for LNAPL recovery, in-situ bioremediation, and operation of a groundwater treatment system from 2018 to 2019; ongoing groundwater monitoring confirms natural attenuation with stable to decreasing contaminant plumes. 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 petroleum contamination beneath this property originated from operations conducted well before 1986 — expert opinion places the release as far back as the early 1970s — during the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The documented remediation expenditures here are substantial: 2,000 cubic yards of excavated soil, LNAPL extraction, in-situ bioremediation, a groundwater treatment system, and multi-year monitoring, with cleanup still active. Historical carriers whose CGL policies were in effect during that pre-1986 operational window may be obligated both to recover costs already incurred and to fund the remediation work that remains.
