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.
The Alf Christianson Seed Company operated an agricultural seed business at this Mount Vernon property, with underground storage tanks supplying gasoline and heavy oil for site operations. Releases of gasoline — including BTEX and lead — and heavy oil hydrocarbons contaminated soil and groundwater at the property. Cleanup under the Voluntary Cleanup Program spanned from 1990 through 2002 and included excavation and off-site disposal of contaminated soils and removal of underground storage tanks. A no-further-action determination was issued for the identified releases. 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 presence of leaded gasoline in the contamination profile confirms that the underground storage tanks at this property were installed and in use well before 1986, when occurrence-based Commercial General Liability policies were standard and carried no effective pollution exclusion in Washington. The documented remediation expenditures — soil excavation, tank removal, and groundwater response across more than a decade — are the type of cleanup costs that historical CGL carriers may be obligated to reimburse. With the site's overall cleanup status still open, additional costs may yet accrue against those same pre-1986 policy periods.
