Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1920. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

This property operated as a gasoline service station for approximately forty years, from the 1920s through the 1960s, with on-site underground storage tanks including a 1,000-gallon gasoline tank, a 280-gallon gasoline tank, and a 55-gallon oil tank. A Phase II Environmental Site Assessment in 1996 confirmed petroleum hydrocarbon contamination in groundwater, and an independent cleanup action was subsequently completed and reported. The site is currently awaiting further cleanup under Ecology's standard 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.

Petroleum contamination at this property originated from fueling operations that began in the 1920s — more than six decades before occurrence-based Commercial General Liability policies gave way to claims-made forms with pollution exclusions in 1986. The documented groundwater contamination from gasoline, diesel, and heavy oil is the type of gradual release that pre-1986 CGL policies were written to cover without restriction. Historical carriers who provided liability coverage during the station's decades of operation may be obligated to fund the cleanup costs this property still faces.

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.
