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.

This property in Lake Stevens operated as an Exxon gasoline dealership — the Lake Stevens Minimart — with underground storage tanks for gasoline and diesel, at least one of which has been unused since the 1960s. Site assessments conducted from 1990 through 1991 identified contamination from degraded gasoline and diesel in the USTs, leading to tank removals in 1992 and a hydraulic lift removal, with excavation of contaminated soil and recovery of an estimated 250 to 500 gallons of liquid product. Follow-up assessment continued through 2002, and the site remains in Awaiting Cleanup status 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 site traces to underground storage tanks that were in service decades before 1986, with at least one tank unused since the 1960s — squarely within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The cleanup costs the property owner faces — tank and soil removal, product recovery, long-term monitoring, and whatever remediation Ecology ultimately requires — could plausibly be funded by historical carriers whose CGL policies were in effect when these tanks were actively dispensing fuel and the contamination first occurred.

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.
