Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1967. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property has a documented history of underground gasoline storage dating to 1967, when a 1,000-gallon gasoline underground storage tank was installed. The tank was removed in the 1970s, but no analytical testing was conducted during removal to confirm whether a release had occurred; no other remediation activities are documented for the site. The property has since reached No Further Action status under the Voluntary Cleanup Program. 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 gasoline UST installed here in 1967 constitutes a Recognized Environmental Condition with a documented moderate-to-high risk of environmental impacts — a release risk that originates squarely in the era when occurrence-based CGL policies were the industry standard and contained no effective pollution exclusion. The absence of analytical sampling at the time of tank removal means the full scope of any historical release was never formally measured, leaving open a recoverable claim against the carriers who insured this property during those pre-1986 operational years.

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.
