Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1979. Historical insurance policies issued during operations at this property and through 1986 could recover the cleanup costs already paid.

This property has operated as Rick's Chevron, an active service station and repair shop, for over 40 years — placing its operational start no later than the late 1970s. Gasoline-range hydrocarbons were released due to a 1992 vendor overfill of the site's underground storage tanks. Cleanup under the Standard Cleanup program included removal of three single-wall steel USTs (totaling 14,000 gallons of capacity) in 1996, excavation of approximately 1,277 tons of contaminated soil across two phases in 1996 and 2016, treatment and discharge of 57,500 gallons of groundwater, application of 600 pounds of Oxygen-Releasing Compound, and ongoing monitoring with institutional controls. 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 petroleum contamination at this property originated from underground storage tanks installed and operated well before 1986, during the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. Two decades of documented remediation expenditures — UST removal, large-scale soil excavation, groundwater treatment, chemical oxidant injection, and long-term monitoring — were incurred to address a release tied to those pre-1986 operations. Historical carriers who issued CGL policies covering this service 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.
