This property has a documented history as a industrial and manufacturing facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This Bothell property operated as the Klaus Insulation industrial facility, where petroleum hydrocarbon products contaminated soil and solvents contaminated both soil and groundwater. Independent remedial actions were undertaken through Washington's Voluntary Cleanup Program, culminating in a Voluntary Cleanup Action Report submitted in January 1998 and a No Further Action determination issued by the Department of Ecology in April 1998. The property has since been redeveloped as Sundquist Homes residential use. 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 at the former Klaus Insulation site — petroleum hydrocarbons and chlorinated solvents characteristic of industrial manufacturing operations — originated well before 1986, when occurrence-based Commercial General Liability policies were the standard and carried no effective pollution exclusion in Washington. The independent remedial actions required to reach a No Further Action determination represent documented cleanup expenditures tied directly to those pre-1986 industrial operations. Historical carriers who issued CGL policies to Klaus Insulation during its operational period may remain obligated to recover those remediation costs.
Restorical's role is to locate viable historical policies, determine whether a successful cost recovery claim is possible, and assist our clients and their legal counsel to obtain insurance coverage for costs already incurred. Restorical's forensic accounting team works to re-establish and document past cleanup expenditures, ensuring the strongest possible basis for recovery.
Recovering Costs from an Older Cleanup
If this site reached No Further Action years ago, the original cleanup expenditures may be difficult to reconstruct. Restorical's forensic accounting team specializes in re-establishing and documenting past cleanup costs — even decades later — to build the strongest possible basis for an insurance recovery claim.
