Gas Station cleanup site — Restorical Research
BP Service Station 11065
Auburn, King County

Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1970. Historical insurance policies issued during operations at this property and through 1986 could recover the cleanup costs already paid.

This property has operated as a gasoline service station since approximately 1970, when its original underground storage tanks were installed. In 1990, five USTs totaling 24,835 gallons were removed and replaced, and excavation of contaminated soils followed along with stockpiling and aeration of affected material. A soil vapor extraction feasibility study was conducted but detected no contaminants, so a full SVE system was not installed. The cleanup project, conducted under the Voluntary Cleanup Program, spanned from 1990 to 2008 and concluded with a No Further Action determination; the station remains in active commercial operation. 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.

Petroleum contamination at this site originated from underground storage tanks installed around 1970 — more than fifteen years before occurrence-based Commercial General Liability policies gave way to claims-made forms with absolute pollution exclusions. The documented remediation expenditures over an eighteen-year cleanup window — tank removal, soil excavation, aeration, vapor extraction testing, and long-term oversight — were incurred to address releases tied directly to those pre-1986 fueling operations. Historical carriers who wrote CGL policies covering this station during that operational window may still be obligated to recover those cleanup costs.

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.
