Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1969. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property was originally developed as a freight trucking terminal in 1969, with a freight warehouse, maintenance shop, and internal diesel fueling operations occupying the site. Contamination was discovered during the removal of five underground storage tanks beginning in 1988, triggering a Voluntary Cleanup Program remediation that ran through 2022. Cleanup activities included excavation and off-site disposal of 1,440 cubic yards of contaminated soil and 600 gallons of petroleum product, recovery and treatment of approximately 3 million gallons of groundwater plus an additional 38,400 gallons removed, and soil vapor extraction that removed 116 pounds of TPH. The site achieved No Further Action status at the conclusion of those efforts. 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.

Diesel fueling and vehicle maintenance at this freight terminal began in 1969 — seventeen years before occurrence-based Commercial General Liability policies stopped reliably covering pollution claims in Washington. The contamination discovered during the 1988 UST removals traces directly to those pre-1986 operations, placing historical carriers who issued CGL policies during that window squarely within the scope of potential cost recovery. The remediation costs documented here — five UST removals, excavation of nearly 1,500 cubic yards of impacted soil, treatment of millions of gallons of groundwater, and over three decades of monitoring — represent precisely the liabilities those pre-1986 policies were written to address.

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.

What We Look For

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.
