This property has a documented history as a bulk fuel distribution terminal going back to 1927. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This Seattle property operated as a large-scale bulk petroleum tank farm from approximately 1927 through the 1960s, with one 30,000-gallon and four 20,000-gallon aboveground storage tanks on site during that period. Storage tanks were removed in 1969, but contamination from those historical operations persists: petroleum free product was identified in groundwater as early as 1990, and passive free product recovery using absorbent tubes has been ongoing since October 1999. Conceptual remediation plans call for excavation of 1,000 to 2,000 cubic yards of contaminated soil and installation of a pump-and-treat groundwater system, with estimated costs of $500,000 to $1,000,000 over a two-to-five-year remediation window. 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.
Bulk petroleum storage at this property began in 1927 — nearly six decades before 1986 — and continued through an era when occurrence-based CGL policies carried no effective pollution exclusion. The contamination profile here includes petroleum free product still migrating in groundwater decades after tank removal, and investigators have recommended testing for tetraalkyl lead, EDB, and EDC given the likelihood of leaded-gasoline releases predating 1996. Historical carriers who issued CGL coverage during the long operational run of this bulk plant may be obligated to fund the substantial excavation and pump-and-treat costs that lie ahead.
