Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1949. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

A Flying A service station operated as a gasoline station and auto repair shop at the southern portion of this property from 1949 through 1961, with historical underground storage tanks and potential belowground hydraulic hoists identified as recognized environmental conditions. Cleanup under the Voluntary Cleanup Program contained petroleum-impacted soil beneath a pavement and asphalt parking cap, with natural attenuation serving as the primary remedial mechanism; quarterly groundwater monitoring was conducted from 2013 through 2015 and again in 2021 and 2022. 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.

The Flying A operator held this corner property for twelve years — 1949 through 1961 — a period during which occurrence-based CGL policies issued to that operator carried no effective pollution exclusion in Washington. The TPH and cPAH contamination documented here traces directly to UST and hydraulic-hoist operations during that specific tenancy, not to any later use of the property. Carriers who wrote coverage for the Flying A operator during its 1949–1961 window may still be obligated to fund the containment and monitoring costs tied to those releases.

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.
