This property has a documented history as a property with a heating oil tank going back to 1900. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
The Ballard Space Building property has been in use since at least 1900, with the building historically heated by an oil-burning steam system supplied by underground storage tanks containing bunker fuel. Remediation under the Voluntary Cleanup Program included the removal of two on-site USTs — including a second tank discovered directly beneath the first — excavation and off-site disposal of approximately 274 tons of contaminated soil, recovery of Bunker C fuel, and installation of a vapor barrier to prevent vapor migration into the structure. The site also received contamination from a migrating plume originating from a 300-gallon heating oil UST on an adjacent property, which was addressed as part of the 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.
The heating oil contamination here originated from USTs installed and operated across many decades before 1986, when occurrence-based Commercial General Liability policies had no effective pollution exclusion. The documented remediation expenditures — dual UST removals, excavation of 274 tons of impacted soil, Bunker C fuel recovery, and vapor barrier installation — trace directly to those pre-1986 heating-oil operations at and adjacent to this property. Historical carriers who issued CGL policies during that operational window may still be obligated to contribute to the costs incurred to resolve this release.
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.
