This property has a documented history as a industrial and manufacturing facility going back to 1891. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
The Puget Sound Naval Shipyard was designated by the Navy in 1891, with its first drydock completed in 1896 and continuous military and industrial operations since. Fill material placed across site zones from the 1940s through the early 1970s included dredge spoils, spent sandblast grit, construction debris, and industrial wastes; beginning in the mid-1950s, sandblasting operations alone consumed 6,000 to 8,000 tons per year of copper slag grit. The selected cleanup remedy for Operable Unit A includes pavement capping of 3.7 acres, installation of 1,400 linear feet of erosion protection, institutional controls, habitat enhancements, and a five-year groundwater monitoring program — construction is complete and the site is in active performance monitoring. 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 operable unit traces directly to sandblasting operations, burn pits, railyard use, and industrial waste disposal that occurred from the mid-1950s through the early 1980s — all within the window when occurrence-based Commercial General Liability policies were in force and carried no effective pollution exclusion. Entities that held CGL coverage during those decades of documented copper slag, paint chip, and industrial waste disposal may retain obligations tied to the contamination those operations caused. The remediation expenditures at this site — capping, erosion control, habitat work, and long-term groundwater monitoring — represent the kind of cleanup cost trail that gives historical carriers' policies continuing legal relevance.
