Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1968. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property served as the Washington Department of Fish and Wildlife's Auburn Shop, a government vehicle maintenance and fueling facility equipped with eight underground storage tanks storing gasoline, diesel, heating oil, and waste oil. Cleanup in 1993 included the removal of all eight USTs and associated product lines, along with excavation of approximately 420 tons of petroleum-contaminated soil, which was disposed off-site. Confirmation sampling verified the site met MTCA Method A cleanup levels, and Ecology issued a No Further Action determination in 2012. 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 petroleum contamination at this facility originated from underground storage tanks estimated to have been installed around 1968 or earlier — well within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The documented remediation costs — tank removals, soil excavation, off-site disposal, confirmation sampling, and nearly two decades of regulatory oversight before final closure — are the type of expenditures that historical carriers who issued CGL policies during the tanks' operational life 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.
