Preliminary Site-Specific Analysis

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

This property operated as a commercial fuel station and car wash at 8200 NE Highway 99 in Vancouver. In August 1999, three gasoline underground storage tanks — two 10,000-gallon and one 6,000-gallon — were removed from the site, and petroleum contamination was identified in groundwater. The site entered the Voluntary Cleanup Program, with groundwater monitoring documented through at least April 2011, and Ecology issued a No Further Action determination in May 2011. 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 USTs removed in 1999 were consistent with installations dating to the 1970s or earlier, placing the origin of petroleum operations and contamination squarely within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The cleanup costs incurred here — tank removal, site investigation, and over a decade of groundwater monitoring — arose from releases tied to those pre-1986 fueling operations. Historical carriers who wrote CGL policies during that operational window may still be obligated to cover those documented remediation expenditures.

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.
