Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1970. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This property was developed as an Exxon gasoline station in 1970, with underground storage tanks installed beginning that year and a leaded-product release documented in August 1984. Petroleum contamination — total petroleum hydrocarbons in the gasoline, diesel, and oil ranges — has been confirmed in soil and groundwater from decades of fuel dispensing operations. Cleanup has included soil excavation, UST and hoist removals, multi-year groundwater treatment via dual-phase and vacuum-enhanced extraction systems recovering over 81,000 gallons of groundwater and thousands of pounds of hydrocarbons, soil vapor extraction, and long-term monitoring. The site continues to operate as a 76 gasoline service station, and cleanup is ongoing. 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 August 1984 leaded-product release at this site occurred while Exxon was the operator — squarely within the era when occurrence-based CGL policies carried no effective pollution exclusion in Washington State. That release, combined with contamination traced to USTs installed from 1970 onward, generated the remediation trail now being worked through: over 81,000 gallons of extracted groundwater, thousands of pounds of hydrocarbons recovered, and years of active extraction systems. Historical carriers who wrote CGL coverage for Exxon's operations at this Kirkland property during those pre-1986 years may be obligated both to recover those documented expenditures and to fund the cleanup costs that remain.

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.
