Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1964. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

Fuel dispensing operations at this property began in 1964, when three 10,000-gallon steel underground storage tanks were installed to hold leaded and unleaded gasoline. The property was originally owned by Autotronic Systems Inc. and sold to ARCO in 1984; the original USTs were removed on October 1, 1989 and replaced with four new tanks. A remedial investigation and cleanup action were completed under Washington's Voluntary Cleanup Program, with petroleum-related contamination — including benzene — confirmed in groundwater. The site has received a No Further Action determination from Ecology. 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 underground storage tanks that are the source of groundwater contamination at this property were installed in 1964 and operated for twenty-five years before removal, placing the origin of contamination squarely within the era of occurrence-based Commercial General Liability coverage. CGL policies issued to the operators during that 1964-through-1986 window carried no effective pollution exclusion under Washington law and remain a viable source of cost recovery. The documented remediation expenditures — tank removal, site investigation, and cleanup action sufficient to achieve a No Further Action determination — represent costs that historical carriers may 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.

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.
