This property has a documented history as a industrial and manufacturing facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This property operated as the Alpha Development Corporation equipment yard, used to store, maintain, and fuel heavy construction machinery. Minor hydraulic oil leaks from staged equipment and diesel fueling activities resulted in petroleum-stained soil, which was addressed in 2005 through excavation and off-site disposal of approximately 11.6 tons (6 cubic yards) of impacted material under the Voluntary Cleanup Program, with spill prevention plans also implemented. Ecology issued a No Further Action determination in 2016. 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 petroleum contamination at this site originated from construction equipment operations established sometime during the 1980s, a period that spans years when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. Hydraulic oil and diesel releases of the kind documented here — gradual leaks from staged machinery rather than a single discrete event — are precisely the slow, ongoing releases those pre-1986 policies were written to cover. Historical carriers who issued CGL coverage to Alpha Development Corporation before 1986 may remain obligated to contribute to the documented remediation expenditures, including soil excavation and off-site disposal.
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.
