Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1963. 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 gasoline fueling station since at least the early 1960s and remains an active AM/PM gas station and convenience store today. Cleanup under the Voluntary Cleanup Program has included the removal of three underground storage tanks and approximately 1,000 cubic yards of contaminated soil in 1988, followed by an additional 380.9 tons of impacted soil removal in 2009. Quarterly groundwater monitoring has been ongoing since 1992, and the current cleanup plan calls for Soil Vapor Extraction and enhanced anaerobic bio-oxidation via magnesium sulfate injection to address petroleum hydrocarbon impacts that remain in place. 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 underground storage tanks removed from this property in 1988 were likely installed around 1963, placing the origin of contamination squarely within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. Decades of documented remediation expenditures — tank removals, large-scale soil excavation, long-term groundwater monitoring, and now engineered bioremediation — were incurred to address releases tied to those pre-1986 fueling operations. With cleanup still underway, historical carriers who issued CGL policies during the facility's early operational window may be obligated both to recover past costs and to fund the remediation work ahead.

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.
