This property has a documented history as a dry cleaning facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
The Lake Tapps Dry Cleaning facility released tetrachloroethene (PCE) into soil and groundwater during its former dry cleaning operations, with the contamination documented as migrating northward from the dry cleaner toward the co-located Mini-Market property. Cleanup work to date has included excavation and off-site disposal of 1,326 tons of petroleum-contaminated soil, upgrades to the underground storage tank system, and multi-year groundwater monitoring. Remediation of the PCE release associated with the former dry cleaning operations was planned for 2018, with additional waste disposal from sampling anticipated as part of that effort. 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 PCE contamination here originated from dry cleaning operations at a facility that, together with its co-located Mini-Market, was in active commercial operation since at least 1981 — well before 1986, when occurrence-based Commercial General Liability policies still carried no effective pollution exclusion in Washington. The documented plume migration, impacted soil, and affected groundwater reflect precisely the kind of slow, continuing release that pre-1986 CGL policies were written to cover. The planned PCE remediation and ongoing groundwater monitoring represent future cleanup expenditures that historical carriers whose policies were in force during those pre-1986 operations may be obligated to fund.
