This property has a documented history as a industrial and manufacturing facility going back to 1936. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
Northwest Cooperage Company operated a drum reconditioning plant at this Seattle property from at least 1936, processing used 55-gallon drums whose residual contents included oils, solvents, paints, and industrial chemicals — handled through hot caustic pre-flushing, exterior washing, dent removal, and repainting. Environmental violations and documented contamination linked to those operations span the 1970s through the 1980s, and cleanup efforts since that era have included installation of wastewater pre-treatment systems, filling of an on-site lagoon, installation of concrete berms, site-wide concrete capping, and off-site disposal of 26,300 pounds of hazardous waste. As of 2014–2015, an active Remedial Investigation/Feasibility Study is underway, well abandonment is in progress, and removal of oily fluid from a buried container has been proposed as a future action. 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 at this property traces directly to drum reconditioning operations that began no later than 1936 — more than four decades before 1986, when occurrence-based Commercial General Liability policies were still the industry standard and carried no effective pollution exclusion in Washington. The residual chemicals involved — PCBs, metals, oils, and industrial solvents processed continuously through the pre-1986 period — represent the gradual, ongoing release pattern those policies were written to cover. With a Remedial Investigation/Feasibility Study still active and additional remediation work yet to be executed, historical carriers who issued CGL coverage during the Northwest Cooperage operating years may be obligated both to fund remaining cleanup and to recover costs already incurred.
