This property has a documented history as a industrial and manufacturing facility going back to 1890. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property was filled from its original tideflat in the late 1800s or early 1900s and operated continuously as a rail yard from the late 1800s through the late 1960s, with engine maintenance buildings, paint shops, track switching areas, and materials storage all part of that century-long industrial footprint. Two gasoline stations also operated on the property from the late 1930s until 1966. Remediation under the Voluntary Cleanup Program included soil excavation of 675 cubic yards on the West parcel in 2011 and 57,009 tons on the East parcel between 2015 and 2018, enhanced bioremediation, and installation of a protective cap across the entire property. The site is now in the performance-monitoring phase, with ongoing groundwater and indoor air monitoring, annual cap inspections, and institutional controls in place. 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.
Nearly a century of railroad and gasoline station operations deposited PAHs, metals, dioxins, furans, and coal tar into soil and groundwater at this property — contamination profiles that are the direct product of industrial activity predating 1986 by decades. Occurrence-based CGL policies issued to rail yard operators and gasoline station owners during that long pre-1986 window carried no effective pollution exclusion and remain potentially enforceable today. The remediation record here — tens of thousands of tons of excavated soil, an engineered site-wide cap, and a continuing monitoring program — represents documented expenditures tied directly to those historical operations, and historical carriers whose policies were in force during that era may be obligated to fund both past costs and ongoing performance monitoring.
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.
