Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1967. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property operated as a gasoline station with three underground storage tanks inferred to have been installed around 1967. In 1992, all three USTs were removed and approximately 1,000 cubic yards of petroleum-contaminated soil was excavated and landfarmed; water in the pump island excavation was also found to be contaminated. The cleanup process spanned 20 years from the initial 1992 tank removal through a No Further Action determination in 2012. 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 underground storage tanks that were in service for roughly 25 years before their removal — placing their installation and the onset of potential releases squarely within the era of occurrence-based Commercial General Liability policies that carried no effective pollution exclusion. Two decades of documented remediation expenditures, from UST removal and large-scale soil excavation to the monitoring required to reach No Further Action status, represent costs that historical carriers who issued CGL policies during the tanks' operational life may still be obligated to cover.

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.
