Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1974. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as the Hunsaker Oil Company service station in downtown Bingen, with three 6,000-gallon underground storage tanks installed in 1974 and in use until 1998. Cleanup activities have included the removal of four USTs totaling 21,000 gallons of capacity and excavation of 72.21 tons of petroleum-contaminated soil in 2000, followed by installation of three groundwater monitoring wells in 2002 and ongoing quarterly groundwater sampling. Soil and groundwater testing identified weathered gasoline, BTEX compounds, and detectable levels of total lead — an indicator of leaded gasoline usage — beneath the former tank locations. 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 originated from underground storage tanks installed in 1974 and operated continuously through the period when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The release has been characterized as "quite old" and the presence of lead in subsurface samples confirms leaded gasoline handling during the pre-1986 policy window. Documented remediation expenditures — tank removal, soil excavation, well installation, and years of groundwater monitoring — represent costs the historical carriers may be obligated both to reimburse and to fund as quarterly monitoring continues.

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.
