This property has a documented history as a industrial and manufacturing facility going back to 1964. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This Bellevue property operated as a US West telecommunications switching office, where two underground storage tanks — a 675-gallon tank installed in 1964 and a 6,000-gallon tank installed in 1974 — stored diesel fuel for a standby generator serving the switching equipment. Both tanks were subsequently removed, triggering a remediation effort that has included approximately 140 cubic yards (106 tons) of petroleum-impacted soil excavated and disposed off-site, incidental removal of perched groundwater, tank cleaning and inerting, and installation of a new double-walled fiberglass tank and upgraded fuel handling system. The cleanup has been ongoing or revisited for more than twenty years under the Standard Cleanup program. 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 petroleum contamination at this property originates from underground storage tanks placed into service in 1964 and 1974 — both well before 1986, when occurrence-based Commercial General Liability policies remained the industry standard and carried no effective pollution exclusion in Washington. More than two decades of documented remediation expenditures — soil excavation, groundwater removal, tank removal and replacement, and continuing oversight — are directly tied to releases from those pre-1986 tank operations. Historical carriers who issued CGL policies to the facility operator during that operational window may remain obligated to fund those cleanup costs, with additional remediation expenditures likely still to come.
