Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1967. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as the Gull Oil and Shell gasoline station from 1967 through 1986, dispensing ethyl and regular leaded gasoline, before 7-Eleven took over and continued operating a convenience store and gasoline station at the location. Two documented gasoline releases — in August 1983 and again in 1990 — drove a remediation effort that has included multiple UST removals and excavations, dual-phase extraction, and soil vapor extraction system operations running from 1995 to 2008, alongside routine groundwater monitoring ongoing since 1993. Future remediation plans call for in-situ treatment and additional soil excavation, and the site remains in active commercial operation today. 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 releases traced to this property began as early as 1983, originating from underground storage tanks that were installed and operating throughout the pre-1986 era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The 1967 tank installations and the 1983 documented release fall squarely within the window those policies covered, making historical carriers plausibly obligated both to recover past remediation expenditures — years of UST removals, dual-phase and vapor extraction, and long-term groundwater monitoring — and to fund the in-situ treatment and excavation work that remains ahead.

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.
