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 fund a cleanup — and recover costs already spent.
The Oberto Sausage manufacturing facility at 1721 Rainier Ave S in Seattle operated underground storage tanks (UST ID 9850) storing diesel and gasoline as part of its industrial operations, alongside the use of halogenated and non-halogenated solvents. Confirmed contamination at the site encompasses petroleum diesel, petroleum gasoline, halogenated solvents, non-halogenated solvents, and other non-halogenated organics in the affected media. Cleanup has officially commenced and is being addressed through the PLIA Petroleum Technical Assistance 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 contamination profile here — petroleum hydrocarbons from underground fuel storage combined with multiple classes of industrial solvents — is consistent with manufacturing operations that may substantially predate 1986, the threshold year after which occurrence-based CGL policies in Washington began routinely including effective pollution exclusions. If the Oberto Sausage facility's tank installations and solvent use trace to that pre-1986 operational period, historical carriers who issued CGL policies during that window may be obligated both to recover documented remediation costs and to fund the ongoing PLIA-program cleanup going forward.
