Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1947. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property was developed as a gasoline service station in 1947, when three 2,000-gallon underground storage tanks were installed on the western portion of the site. The USTs operated until at least 1970 and were removed in 1989, at which point gasoline releases were discovered. Cleanup to date has included excavation of 250 cubic yards of contaminated soil, treatment of 800 gallons of groundwater, and installation of an ongoing bioremediation and recirculation system with groundwater monitoring. Future remediation — an estimated 1,300 tons of additional soil excavation, pump-and-treat of 2,000 to 3,000 gallons of groundwater, bioremediation product injection, and potential soil vapor extraction — carries a projected cost of $1,200,000. 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 traces directly to underground storage tanks installed in 1947 and operated for decades — nearly four decades before 1986, when occurrence-based Commercial General Liability policies still carried no effective pollution exclusion in Washington. The remediation cost trail here is substantial and still growing: past cleanup work is already on the books, and a $1.2 million phase of excavation, groundwater treatment, and bioremediation lies ahead. Historical carriers who issued CGL policies covering this property during that pre-1986 operational window may be obligated both to reimburse costs already incurred and to fund the cleanup work still to come.

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.
