Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1940. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property operated as a gasoline station with a service bay and retail building from the 1940s through the late 1980s, located on the Kittitas County side of Snoqualmie Pass. An Independent Cleanup Action completed in 2009 under the Voluntary Cleanup Program included removal of underground storage tanks — with the original station foundations still in place — and recovery of approximately 12,400 gallons of contaminated groundwater. 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.

Gasoline station operations at this property began in the 1940s, more than four decades before occurrence-based CGL policies stopped reliably covering pollution claims in 1986. Benzene and petroleum hydrocarbons detected in groundwater here are consistent with decades of fuel storage and dispensing from underground tanks installed during that pre-1986 window. The documented 2009 cleanup expenditures — UST removal, groundwater recovery, and associated investigation — represent costs that historical carriers who issued CGL policies during the station's operating years may still 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.
