Industrial & Manufacturing cleanup site — Restorical Research
Truss Span
Redmond, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1969. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

Truss Span Corporation operated as a wood truss span manufacturer at this Redmond property from 1969, with industrial activities that included drum storage on bare ground and an above-ground diesel tank servicing a truck wash area. Cleanup activities between 1990 and 1995 addressed both areas, encompassing the removal of drums of hazardous materials and the diesel tank. Washington State Ecology issued a no further action determination in 1996. 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.

Drum storage and diesel fuel handling at this property date to 1969, placing the contamination origin nearly two decades before occurrence-based Commercial General Liability policies began routinely excluding pollution claims in 1986. The drum storage area on bare ground and the diesel tank operations are precisely the type of ongoing industrial releases those pre-1986 policies were underwritten to cover. Historical carriers who issued CGL policies to Truss Span Corporation during that operational window may still be obligated to fund recovery of the documented remediation expenditures incurred between 1990 and 1995.

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.

The Restorical Proven Process

Task 1 — Research and Analysis
Restorical searches for viable historical insurance policies, researches the site history, analyzes the contamination impacts, and underwrites potential coverage — including a proprietary trigger analysis. At the end of Task 1, we provide a clear yes or no on whether a successful cost recovery is possible, along with a strategy and recommendation specific to your situation, even if you are not the policyholder.
Task 2 — Cost Recovery
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim and negotiate recovery of costs already incurred. Restorical's forensic accounting team re-establishes and documents past cleanup expenditures, managing the claim process to ensure the insurance companies fulfill their obligation in a timely manner.
