Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1930. Historical insurance policies issued during operations at this property and through 1986 could recover the cleanup costs already paid.

This bulk petroleum distribution facility was constructed in the 1930s and has operated continuously under UNOCAL and its lessees, with infrastructure including five aboveground fuel storage tanks, a pumping station, three loading racks, and oil/water separators. Petroleum-contaminated soil was first identified and excavated in 1989; remaining contamination was capped beneath a building and concrete floor, and an Environmental Covenant was recorded to enforce institutional controls. The site now operates under an ongoing monitoring program covering groundwater, soil gas, annual cap inspections, and periodic covenant reviews. 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.

The 1989 soil excavation was the opening act of a cleanup trail that traces directly to bulk petroleum operations running decades before 1986. Every cost that followed — the impervious cap installation, Environmental Covenant implementation and modifications, and a multi-decade monitoring regime spanning groundwater, soil gas, and annual structural inspections — is tied to a release window squarely within the era of occurrence-based CGL coverage. Carriers who insured this facility or its operators during that pre-1986 period may bear responsibility for those accumulated remediation expenditures.

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.
