Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1959. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This property has operated as a retail gasoline station since 1959, originally as an Exxon site with multiple underground storage tanks for gasoline and diesel. Cleanup under the Voluntary Cleanup Program has included the removal of eight USTs in 1989, excavation and off-site disposal of approximately 1,115 cubic yards of petroleum-contaminated soil across campaigns in 1989 and 2005, operation of a soil vapor extraction and air sparging system from 1995 to 2000 that recovered 600 pounds of volatile petroleum hydrocarbons, in-situ chemical oxidation injections using nearly 12,000 pounds of oxidizers in 2011, and groundwater monitoring ongoing since 1990. The property remains in active use as a service station with a convenience store. 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 to underground storage tanks installed and operated continuously from the late 1950s — more than a quarter century before 1986, when occurrence-based CGL policies still carried no effective pollution exclusion in Washington. The remediation cost trail already spans decades: tank removals, large-scale soil excavation, five years of vapor extraction, chemical oxidation, and long-term groundwater monitoring still underway. Historical carriers who wrote CGL policies during that pre-1986 operational window may be obligated both to reimburse past cleanup expenditures and to fund the remediation work that remains.

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.
