Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1978. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property has operated as a retail gasoline station and small grocery store since 1978, with three underground storage tanks, associated piping, and a dispenser island serving as the fuel distribution infrastructure. A gasoline release from the 1978-vintage UST system was discovered in 2009, prompting cleanup that included UST removal, excavation of over 1,300 cubic yards and 2,300 tons of contaminated soil, recovery of 1,250 gallons of free product, and removal of affected wetland vegetation and sediment. Long-term groundwater monitoring, institutional controls, and Monitored Natural Attenuation have been selected as the ongoing remedy, with cleanup work continuing under the Voluntary 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 gasoline contamination at this site originated from underground storage tanks installed in 1978 — eight years before occurrence-based Commercial General Liability policies gave way to claims-made forms with absolute pollution exclusions. The documented remediation expenditures already incurred — tank removal, large-scale soil excavation, free product recovery, wetland restoration — plus an estimated $50,000 in ongoing monitoring costs represent the kind of long-tail environmental liability that pre-1986 CGL policies were written to cover. Historical carriers who provided coverage during the 1978–1986 operational window may be obligated both to reimburse past cleanup costs and to fund the remediation still underway.

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.
