This property has a documented history as a industrial and manufacturing facility going back to 1946. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
Spencer Industries operated this Seattle property as a manufacturing and distribution center from 1946 through 1996, assembling and repairing aircraft hydraulic components and fasteners and using trichloroethylene (TCE) as an industrial degreaser. Cleanup activities in the early 1990s included the excavation and offsite disposal of above-ground storage tanks (ASTs) and petroleum-impacted soil, followed by groundwater monitoring from 1996 through 1999 and an assessment of natural attenuation for chlorinated solvents. At an associated South Park Bridge parcel, 100 cubic yards of PCE-contaminated soil were separately excavated, managed, and prepared for offsite disposal along with associated contaminated water. Cleanup remains ongoing under the Voluntary 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.
TCE degreasing and AST operations at this site began in 1946 — four decades before the 1986 threshold at which occurrence-based Commercial General Liability policies gave way to forms with effective pollution exclusions. The contamination profile here — TCE and PCE in soil and groundwater alongside petroleum hydrocarbons from storage tanks — reflects precisely the kind of long-running industrial release those pre-1986 policies were written to cover. Historical carriers who issued CGL policies to Spencer Industries during its fifty years of active operations may be obligated both to recover documented remediation expenditures and to fund the cleanup work that remains ahead.
