Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1948. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as a gasoline service station from 1948 until approximately 1973, with Texaco, Signal Oil, and Exxon among its successive operators. Underground storage tanks were installed and replaced on site — including new USTs in 1964 — and cleanup activities have included UST and fuel-line removals in 1995, excavation of approximately 500 cubic yards of contaminated soil from former pump island areas, and long-term groundwater monitoring with observed natural attenuation ongoing since 2002. Following closure of the service station, the property was repurposed as a contractor yard for equipment and supply storage. 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 — lead and aged gasoline in soil and groundwater — originated from fueling operations that began in 1948, nearly four decades before occurrence-based CGL policies ceased covering pollution claims in 1986. Texaco, Signal Oil, and Exxon each operated the station during the pre-1986 window when those policies carried no effective pollution exclusion. The documented remediation expenditures already incurred — tank removals, large-scale soil excavation, and over two decades of groundwater monitoring — along with costs still accumulating represent obligations the historical carriers who insured those operators may be required to fund.

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.
