This property has a documented history as a property with a heating oil tank predating 1986. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
The Minolta Building, a commercial property in Tukwila, was listed as a Leaking Underground Storage Tank site after a petroleum release from an underground heating-oil tank installed well before modern UST regulations took effect. Independent remedial actions culminated in a Clean-up Final Report in October 1992, followed by post-remediation groundwater sampling in September 1993 and March 1994. The site received a No Further Action determination, and it no longer appears in Ecology's LUST publications. 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 tank at this property was installed and operating before 1986, and the petroleum release it caused required independent remedial action, a multi-year groundwater monitoring program, and a formal cleanup report before the site could be closed out in the mid-1990s. Those remediation expenditures — documented from 1992 through at least 1994 — arose from a release tied to pre-1986 tank operations, when the building's CGL carriers were issuing occurrence-based policies with no effective pollution exclusion in Washington. Historical carriers on the risk during that operational window may still owe a duty to cover the cleanup costs incurred.
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.
