This property has a documented history as a industrial and manufacturing facility going back to 1960. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
This property has hosted aerospace manufacturing operations since the early 1960s, with chlorinated solvents — trichloroethylene (TCE), 1,1,1-trichloroethane (TCA), and perchloroethylene (PCE) — used in the manufacture of electronic components for the aerospace industry. Cleanup activities under the Voluntary Cleanup Program have been ongoing since 1987, including removal of a 3,000-gallon underground storage tank, excavation of a TCA spill area to 16 feet deep, and removal of TCE-contaminated soil to depths of 20 feet during building demolition. Groundwater remediation is currently being evaluated, with monitored natural attenuation under consideration as a potential remedy. 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.
Chlorinated solvent contamination at this site traces directly to aerospace manufacturing operations that began more than two decades before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. Nearly four decades of documented remediation expenditures — tank removal, deep soil excavation, contaminated-soil disposal, and ongoing groundwater investigation — were incurred to address releases tied to those pre-1986 industrial operations. Historical carriers who issued CGL policies during that operational window may be obligated both to recover past cleanup costs and to fund the groundwater remedy still ahead.
Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.
