This property has a documented history as a gasoline service station predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property served as a vehicle maintenance, fueling, and staging facility with multiple underground storage tanks for gasoline, diesel, and used oil — one of which held leaded gasoline until approximately 1980. Cleanup under the Voluntary Cleanup Program has included the removal of USTs in 1993, 1995, and 2013, excavation of over 1,700 tons of contaminated soil across multiple phases, installation of a soldier pile wall for excavation support, and a long-term groundwater monitoring program dating back to 1999 and continuing through at least 2020. 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 site originated from underground storage tanks that stored leaded gasoline, diesel, and used oil well before 1986 — the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. More than two decades of documented remediation expenditures, from multi-phase UST removals and large-scale soil excavation to ongoing groundwater monitoring, represent costs that historical carriers who issued CGL policies during the pre-1986 operational window may be obligated both to reimburse and to fund going forward.
