Preliminary Site-Specific Analysis

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

This property at 936 121st Ave SE in Bellevue operated a fuel island with multiple underground storage tanks dispensing gasoline and diesel, with at least one tank (Tank 4) documented as having been emptied in the 1980s. Contamination — characterized by regulators as an old release — is attributed to leakage at a pipe union and possible spillage at the pump dispenser unit and/or fill port. A cleanup project initiated around 2003 removed all four USTs along with approximately 730 tons of petroleum-contaminated soil, 5,400 gallons of gasoline, and 3,100 gallons of rinsate; additional excavation has been recommended to address remaining contaminated soil and perched groundwater. 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 Tank 4 documentation — confirming that tank was emptied in the 1980s — places active fueling operations at this site squarely in the pre-1986 period when occurrence-based CGL policies were the industry standard. The 2003 remediation scope alone encompassed four UST removals, 730 tons of contaminated soil, and thousands of gallons of recovered product, all tied to contamination regulators describe as an old release from those historical operations. Historical carriers whose policies were in force during that pre-1986 operational window may be obligated to contribute to those documented remediation expenditures.

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.
