Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1905. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

Chevron operated a bulk fuel terminal at this property from 1905 through 1984, nearly eight decades of continuous petroleum storage and distribution at the Port of Seattle's Terminal 30. The Port purchased the site from Chevron in January 1985, and the terminal was demolished between late 1984 and November 1985; two underground storage tanks were subsequently removed in 1991 after a release was reported in 1990. Groundwater beneath the site was found to contain free-phase petroleum product, benzene, PAHs, and diesel- and gasoline-range hydrocarbons, and over 171,000 gallons of product were recovered by the early 1990s. The site 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.

Chevron's nearly eighty years of fuel-terminal operations at this property — 1905 through 1984 — span a period when occurrence-based Commercial General Liability policies carried no effective pollution exclusion and were routinely issued to petroleum operators. The scale of the documented release here, including 171,000 gallons of recovered product and benzene and PAH contamination in groundwater, represents substantial remediation expenditures tied directly to operations conducted under those pre-1986 Chevron policies. Historical carriers that insured Chevron's fuel-terminal operations during that window may still be obligated to cover the cleanup costs incurred at this site.

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.
