Preliminary Site-Specific Analysis

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

This property served as a gasoline fueling facility with two underground storage tanks — one 6,000-gallon and one 10,000-gallon — and sidewalk-mounted fuel dispensers. The USTs, which formerly contained gasoline, were removed on January 15, 1998, and cleanup under the Standard Cleanup program included excavation and off-site thermal desorption treatment of approximately 346 tons of petroleum-contaminated soil. Groundwater contamination was observed at the site but was not actively treated due to site conditions. 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 release at this property originated from underground storage tanks installed and operated well before 1986, during the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The documented remediation expenditures — tank removal, extensive soil excavation, and off-site thermal treatment of hundreds of tons of contaminated material — represent costs tied directly to those pre-1986 fueling operations. Historical carriers who issued CGL policies covering this facility during its operational window may be obligated both to recover past cleanup costs and to fund any remaining remediation work.

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.
