This property has a documented history as a industrial and manufacturing facility going back to 1931. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
The Tacoma DPU Steam Plant 2 was constructed by the City of Tacoma in 1931 and initially burned pulverized coal before converting to Bunker C fuel oil in the late 1940s; a significant Bunker C release in 1977 deposited contamination that the site's own records identify as a continuing contributor to current conditions. Remediation between 1977 and 2010 removed at least 2,300 tons of contaminated soil through multiple excavation campaigns, alongside capping, stabilization, thermal treatment, and hazardous materials and ash removal. The site remains open under the Voluntary Cleanup Program, with an ongoing Remedial Investigation/Feasibility Study, new groundwater monitoring well installations, and previous PCB management programs still on record. 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 1977 Bunker C release — explicitly cited in site documents as a source still driving the RI/FS-scoped contamination — occurred when occurrence-based CGL policies were the coverage standard for municipal utility operators, and the pre-1986 policies in effect at the time of that release carried no effective pollution exclusion in Washington. The remediation record here is substantial: 2,300-plus tons of excavated soil, PCB management programs, and a still-open feasibility study represent documented expenditures tied directly to that operational history. Historical carriers whose policies were in force during the decades spanning the 1977 release and the plant's broader pre-1986 operations may be obligated both to recover those costs and to fund the cleanup work that remains.
Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage.
