Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1950. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property, developed prior to 1904, hosted auto repair operations by circa 1950 and a fleet-fueling operation served by three single-walled steel underground storage tanks. The USTs were discovered and decommissioned during redevelopment in 2017; their single-walled steel construction — a design phased out under 1988 federal UST regulations — is consistent with installation well before 1986. Petroleum-gasoline contamination was identified in groundwater and soil vapor, and the site has received a No Further Action determination under the state 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 fleet-fueling and auto repair operations at this property date to at least 1950, placing more than three decades of petroleum handling squarely within the era of occurrence-based Commercial General Liability policies that carried no effective pollution exclusion. The petroleum-gasoline contamination detected in groundwater and soil vapor traces to those pre-1986 operations, and the costs incurred through UST decommissioning and site investigation represent expenditures that historical carriers who issued CGL policies during the operational window may be obligated to cover.

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.
