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.
This Tacoma property has hosted industrial chemical manufacturing since before 1949, when Rainier Steel Co. operated the site before Stauffer Chemical Company took over and launched decades of superphosphate fertilizer and alum production. Fertilizer production ceased in 1978, alum manufacturing continued until 1993, and the facility was fully dismantled in 1994. Cleanup activities in 1993 included removal of a 1,000-gallon underground storage tank and associated petroleum-contaminated soils, along with excavation and offsite disposal of contaminated evaporation ponds and alum mud piles; follow-up reporting continued through 1997, and the cleanup remains ongoing. 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 mercury, DDT, and metal contamination documented at this property is the direct product of chemical manufacturing operations conducted for decades before 1986 — operations covered by occurrence-based CGL policies that carried no effective pollution exclusion in Washington at the time. The scope of documented remediation work — tank removal, soil excavation, and disposal of contaminated ponds and alum mud piles — reflects a contamination legacy tied squarely to those pre-1986 manufacturing years. Historical carriers whose policies covered Stauffer Chemical or its predecessors during that window may be obligated both to fund remaining cleanup costs and to recover expenditures already incurred.
