This property has a documented history as a landfill going back to 1890. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This property sits atop 16 to 42 feet of uncontrolled fill material — the remnant of landfilling activity in the Wetmore Slough area dating to the 1890s — with additional contamination attributed to 141 creosote-treated piles from a building constructed in 1967 and the adjacent former Genesee landfill. Under the Voluntary Cleanup Program, remediation included excavation of more than 61,000 tons of impacted soil, removal of all 141 creosote piles, and installation of a vapor mitigation system with a vapor barrier, passive venting, active ventilation, and methane sensors. Long-term compliance groundwater monitoring with quarterly sampling continues under institutional controls comprising environmental covenants, capping, and containment by the new building foundation. The site has received a No Further Action determination. 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 — petroleum hydrocarbons, carcinogenic PAHs, lead, and methane — originates from more than a century of uncontrolled fill activity and creosote pile infrastructure installed in 1967, all predating 1986 by decades and in some cases by nearly a century. Valley Fuel Company operated at this location from at least 1917 through 1929, and documented landfilling across the surrounding area began as early as the 1890s — well within the window when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The remediation record here — 61,000-plus tons of excavated soil, a permanent vapor mitigation system, and ongoing quarterly groundwater monitoring — represents the kind of sustained, documented expenditure that pre-1986 CGL carriers may remain obligated to address.
Restorical's role is to locate viable historical policies, determine whether a successful cost recovery claim is possible, and assist our clients and their legal counsel to obtain insurance coverage for costs already incurred. Restorical's forensic accounting team works to re-establish and document past cleanup expenditures, ensuring the strongest possible basis for recovery.
Recovering Costs from an Older Cleanup
If this site reached No Further Action years ago, the original cleanup expenditures may be difficult to reconstruct. Restorical's forensic accounting team specializes in re-establishing and documenting past cleanup costs — even decades later — to build the strongest possible basis for an insurance recovery claim.
