Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1943. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property hosted two gasoline service stations from 1943 through 1987, with three underground storage tanks and associated piping systems dispensing fuel over that period. A Phase II investigation beginning in 2003 confirmed petroleum hydrocarbon contamination from gasoline releases tied to those former USTs. Cleanup under the Voluntary Cleanup Program included excavation of impacted soil, removal and disposal of three 500-gallon USTs, and natural attenuation for groundwater remediation, culminating in a No Further Action determination in 2009. 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.

Gasoline service operations at this site began more than four decades before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion in Washington. The contamination discovered here — petroleum hydrocarbons from underground storage tanks and piping installed during that pre-1986 window — is precisely the kind of gradual release those policies were written to cover. The documented remediation expenditures from 2003 through 2009, including tank removal, soil excavation, and long-term groundwater monitoring, represent costs that historical carriers who insured the station operators may still be obligated to reimburse.

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)

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.
