Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1971. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

Gull Industries purchased this property in 1971 for use as a gasoline service station, installing four underground storage tanks with a combined capacity of 36,000 gallons of diesel and gasoline that same year. A retail fuel store was constructed in approximately 1972 and a convenience store added around 1980. Site investigations identified benzene, petroleum hydrocarbons, lead, metals, and non-halogenated solvents in soil and groundwater, with benzene and oil-range hydrocarbons exceeding MTCA Method A cleanup levels. The site entered the Voluntary Cleanup Program and has since received a No Further Action determination. 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.

Underground storage tanks at this property were installed in 1971 and gasoline dispensing operations ran continuously through at least 1989, placing more than a decade of fuel-station operations squarely within the pre-1986 window when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The petroleum and metals contamination documented in soil and groundwater here originated from those operations, and the full remediation cost trail — from initial investigation through cleanup to the No Further Action milestone — represents expenditures that historical carriers who issued CGL policies during the 1971–1986 period may still be obligated to cover.

Restorical's role is to locate viable historical policies, determine whether a successful cost recovery claim is possible, and assist our clients and their legal counsel to obtain insurance coverage for costs already incurred. Restorical's forensic accounting team works to re-establish and document past cleanup expenditures, ensuring the strongest possible basis for recovery.

Recovering Costs from an Older Cleanup

If this site reached No Further Action years ago, the original cleanup expenditures may be difficult to reconstruct. Restorical's forensic accounting team specializes in re-establishing and documenting past cleanup costs — even decades later — to build the strongest possible basis for an insurance recovery claim.

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 — Cost Recovery
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim and negotiate recovery of costs already incurred. Restorical's forensic accounting team re-establishes and documents past cleanup expenditures, managing the claim process to ensure the insurance companies fulfill their obligation in a timely manner.
