This property has a documented history as a industrial and manufacturing facility going back to 1880. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
The Roslyn No. 4 Mine operated as an underground coal mine from the 1880s until approximately 1909, with subsequent industrial activity on the property including a foundry that ran through the mid-1970s and electrical transformers present from the 1960s into the 1980s. The property is currently vacant and enrolled in Washington's Voluntary Cleanup Program, with a planned remedy centered on full excavation of approximately 560 cubic yards of contaminated soil from six discrete areas and offsite disposal. Additional remediation measures include backfilling with clean soil, potential capping, wetland restoration, erosion and dust control, and waste characterization, with post-remedy groundwater and soil monitoring to confirm effectiveness. 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.
Contamination at this property — metals, petroleum hydrocarbons, and polycyclic aromatic hydrocarbons — traces to industrial operations that spanned more than a century, all predating 1986: coal mining from the 1880s, foundry work through the mid-1970s, and transformer equipment into the early 1980s. Occurrence-based CGL policies issued to operators during any of those pre-1986 windows carried no effective pollution exclusion and remain potentially enforceable today. The forthcoming cleanup — soil excavation and offsite disposal, capping, wetland restoration, and long-term monitoring — represents costs that historical carriers may be obligated to fund.
