Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1946. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property entered service in 1946 as an automobile repair garage, gas station, and sales facility, with three 1,000-gallon underground storage tanks and fuel dispenser pumps installed on the initial parcel. A second parcel was developed in 1953 with an additional 2,000-gallon UST and dispenser pump; over the decades the site also housed dry cleaning, machine shop, and auto parts operations. Investigations under the Voluntary Cleanup Program identified halogenated solvents, benzene, and petroleum hydrocarbons in groundwater, and the site has since received a No Further Action determination. 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.

Fuel storage and dispensing operations at this Bellevue property began in 1946 — forty years before occurrence-based Commercial General Liability policies gave way to claims-made forms with pollution exclusions. The groundwater contamination documented here, including halogenated solvents and petroleum hydrocarbons, is consistent with the types of slow, cumulative releases that those pre-1986 policies were designed to cover. Historical carriers who wrote CGL coverage during the four decades of pre-1986 operations at this site may still bear obligation for the remediation costs incurred to reach the property's current No Further Action status.

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.

What We Look For

  • Historical insurance policies (pre-1986)

  • Claims Management & Forensic Accounting

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.
