This property has a documented history as a property with a heating oil tank going back to 1950. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This industrial warehouse property at 2450 6th Ave S in Seattle housed at least four underground storage tanks used for heating fuel, installed in the early- to mid-1950s. Cleanup under the Voluntary Cleanup Program included free product recovery, removal of one UST, and in-place decommissioning of three additional heating fuel USTs located beneath the warehouse's concrete slab floor. A two-year semi-annual groundwater monitoring program followed, and the site reached No Further Action status subject to a Restrictive Covenant restricting land and groundwater use and prohibiting disturbance of contaminated soil beneath the warehouse. 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 fuel contamination at this property traces directly to underground storage tanks installed more than three decades before 1986, when occurrence-based Commercial General Liability policies were standard and carried no effective pollution exclusion. The documented remediation — free product recovery, UST removal, in-place decommissioning of three tanks, and a multi-year groundwater monitoring program — represents past expenditures tied to releases that originated during that pre-1986 coverage window. Historical carriers who issued CGL policies to the operators of this property during that period may still be obligated to recover those past cleanup costs.
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.
