Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1972. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property operated as an active retail gasoline station and convenience store under The Southland Corporation, with three 12,000-gallon underground storage tanks, a dispenser island, and underground product piping serving three grades of gasoline. The USTs were decommissioned and removed in March 1997, along with approximately 30 cubic yards of petroleum-contaminated soil that was excavated and sent for thermal treatment. Five groundwater monitoring wells were installed and a multi-year quarterly monitoring program was conducted under the Voluntary Cleanup Program, culminating in a No Further Action determination by Ecology. 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 estimated to have been installed around 1972 and operated continuously through 1997 — placing over a decade of fuel-dispensing operations squarely within the pre-1986 window when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The documented remediation expenditures — tank removal, soil excavation and thermal treatment, monitoring well installation, and years of quarterly groundwater sampling — represent cleanup costs that historical carriers who covered The Southland Corporation during that operational period may still be obligated to recover.

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.
