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 sold gasoline from two underground storage tanks at a site in Brush Prairie, Clark County, with operations predating 1986. Both USTs were removed in March 1990, along with approximately 40 cubic yards of contaminated soil that was treated by aeration and soil vapor venting. A Vapor Extraction System operated from June 1991 through July 1992, recovering an estimated 700 pounds of petroleum product, and remediation under the Voluntary Cleanup Program continued through at least 2005. Cleanup work at the site is ongoing. 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 here originated from underground storage tanks that were in service well before 1986 — the presence of lead in soil samples points to leaded-gasoline-era operations, confirming the pre-1986 operational window. Occurrence-based CGL policies written during that period carried no effective pollution exclusion in Washington and remain enforceable today. Fifteen years of documented remediation expenditures — tank removals, soil excavation and treatment, vapor extraction, and long-term site management — represent costs that historical carriers may be obligated to reimburse and to continue funding.

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.
