Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1940. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property served as a petroleum bulk storage and home fuel distribution facility from the late 1930s or early 1940s through 1992, with Cornwall Fuel and Lumber Company operating the fuel distribution, hardware store, and lumber yard from 1966 onward. The fuel facility consisted of four underground storage tanks — a 550-gallon gasoline UST, a 10,000-gallon diesel UST, and two 12,000-gallon heating oil USTs. Cleanup under the Voluntary Cleanup Program from 1988 to 1993 included removal of all four USTs, excavation of approximately 1,500 cubic yards of petroleum-contaminated soil, on-site bioremediation and reuse of excavated material as backfill, and discharge of 30,000 gallons of accumulated water to the sanitary sewer. The site has 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.

Petroleum storage and distribution at this property began roughly five decades before 1986, when occurrence-based Commercial General Liability policies still carried no effective pollution exclusion. The contamination that triggered cleanup — petroleum releases from four underground storage tanks installed and operated across that pre-1986 window — is precisely the kind of long-duration release those policies were written to cover. The documented remediation costs, from tank removal and large-scale soil excavation to bioremediation and water management, represent expenditures that historical carriers who insured the fuel distribution operation 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

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.
