Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1974. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as a fueling facility with four underground storage tanks — one 6,000-gallon diesel, one 8,000-gallon super unleaded, and two 10,000-gallon tanks — along with a pressurized piping system, all installed in 1974. Tank integrity testing conducted in 1989 and 1992 confirmed the long-standing presence of this infrastructure, and a 1995 subsurface soil investigation identified petroleum-contaminated soil at depths of five to six feet below ground surface, where water-saturated conditions were encountered. Groundwater has been confirmed as an affected medium, and cleanup is underway under Washington's Standard 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 petroleum contamination at this site traces directly to underground storage tanks and pressurized piping installed in 1974 — more than a decade before 1986, when occurrence-based Commercial General Liability policies still carried no effective pollution exclusion. The documented contamination of both soil and groundwater from those pre-1986 fueling operations represents the kind of long-duration release that historical CGL policies were structured to cover. Cleanup costs already incurred and those still ahead may be recoverable from the carriers who insured this facility during the years the tanks were in active service.

Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.

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 — Coverage and Funding
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim, negotiate and secure insurance coverage. Restorical will manage the ongoing claim process, including accounting to ensure the insurance companies are funding your remediation in a timely manner.
