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.
The Astro #617 site operated as a gasoline service station with at least five underground storage tanks, including two (T4 and T5) that previously contained and released leaded gasoline — a direct indicator of pre-1986 operations. A release of petroleum hydrocarbons was discovered in December 1996 during decommissioning of the UST system; cleanup has since included removal of all five tanks, excavation and thermal treatment of 278 tons of contaminated soil, and installation of two groundwater air sparging systems with passive vapor venting, operational since 1998 and 2001. Remediation remains active today through annual groundwater monitoring, bioremediation, and ongoing maintenance of the in-place sparging infrastructure. 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 leaded gasoline residues in tanks T4 and T5 anchor the contamination at this site to an operational era that predates the 1986 industry shift away from occurrence-based CGL policies. Two air sparging systems have run continuously since 1998 and 2001, annual monitoring and bioremediation remain active, and the remediation arc now spans nearly three decades with no end date set — a timeline directly traceable to releases from those pre-1986 tank operations. Carriers who issued occurrence-based CGL policies to the Astro operators during the leaded-gasoline era may be obligated to fund both the costs already incurred and the remediation that continues at this Olympia property.
