Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1968. 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 Chevron gasoline service station since 1968, with four dispenser islands, a station building, and a car wash. Cleanup under the Voluntary Cleanup Program has included removal of three 10,000-gallon gasoline USTs and a 300-gallon waste oil UST, excavation of over 1,000 tons of petroleum-impacted soil, pumping and disposal of more than 16,000 gallons of contaminated groundwater, and installation of dewatering wells and an aboveground water treatment system. Vapor extraction wells have been installed, and multi-year groundwater monitoring has been ongoing since at least 1990. The station remains in active commercial operation. 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 originated from underground storage tanks installed and operated beginning in 1968 — nearly two decades before occurrence-based Commercial General Liability policies gave way to claims-made forms with absolute pollution exclusions. The detection of lead in groundwater and waste oil confirms releases tied to the era of leaded gasoline, anchoring the contamination squarely in the pre-1986 policy window. Decades of documented remediation expenditures — tank removals, large-scale soil excavation, groundwater treatment, vapor extraction, and long-term monitoring — represent costs that historical CGL carriers may be obligated both to reimburse and to fund as cleanup continues.

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.
