This property has a documented history as a farm and agricultural operation predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property was formerly the site of a residence with two unregulated underground storage tanks: a 500-gallon home heating oil UST and a 500-gallon farm gasoline UST, the latter identified as the primary source of site contamination. In 2014, both tanks were removed and 2,438 tons of petroleum-impacted soil were excavated and disposed of offsite under the Voluntary Cleanup Program. Quarterly groundwater monitoring followed from 2016 through 2024, and remaining obligations include establishing an Environmental Covenant with long-term cap monitoring and a contaminated media management plan to address residual soil contamination. 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 contamination here traces to unregulated underground storage tanks associated with a former residence — a designation that implies installation and operation well before the federal UST regulations that became effective in 1986 for existing tanks. Occurrence-based CGL policies issued to the property operators during that pre-1986 window carried no effective pollution exclusion and remain enforceable today. The documented remediation expenditures — dual UST removals, nearly 2,500 tons of soil disposal, years of groundwater monitoring, and the forthcoming Environmental Covenant — represent both past costs to recover and future compliance obligations that historical carriers may be obligated to fund.
