This property has a documented history as a farm and agricultural operation going back to 1960. 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 hog dip facility on the agricultural land of the Rainier School, a Washington State institution managed by the DSHS Building and Lands Division, with chlorinated pesticide applications to hogs conducted from the 1960s through the early 1990s. Environmental investigations dating to 1996 identified toxaphene contamination in soil and groundwater at the site. In 2010, cleanup activities removed 65.87 tons of debris and over 600 cubic yards (approximately 590 tons) of toxaphene-contaminated soil, and an ex situ bio-treatment system was dismantled and disposed of. Planning for remediation of remaining soil and groundwater contamination is ongoing 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.
The toxaphene contamination here originated from pesticide applications that began in the 1960s — more than two decades before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion in Washington. Institutional operators held such policies during the full span of active hog dip operations, and those policies remain potentially enforceable today. The documented remediation expenditures — site investigations since 1996, large-scale soil excavation, bio-treatment system removal, and continuing cleanup planning — represent costs that historical carriers may be obligated both to recover and to fund through completion.
