Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property served as a Washington State Department of Transportation maintenance facility and service station, originally developed between the 1930s and 1960s, with operations encompassing fuel dispensing, equipment storage, painting, welding, and a materials laboratory. Underground storage tanks holding gasoline, diesel, and waste oil were decommissioned between 1989 and 1997 after decades of active use predating 1986. Remediation to date has included UST removal, soil excavation, and a land farm operation for petroleum-contaminated soils, along with offsite disposal of approximately 100 tons of impacted soil. Planned groundwater remediation under the Voluntary Cleanup Program calls for multi-year in-situ injection of chemical reduction and bioremediation compounds combined with monitored natural attenuation and institutional controls, at an estimated cost of $577,159. 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 underground storage tanks at this WSDOT facility were installed and operated for decades before 1986, when occurrence-based Commercial General Liability policies were still the industry standard and carried no effective pollution exclusion in Washington. The petroleum contamination documented in soil and groundwater here traces directly to those pre-1986 operations — fuel dispensing, maintenance activities, and waste oil handling at a government-run service station and maintenance complex. The documented remediation trail, from early UST removals and land farm treatment through a planned six-figure groundwater remedy, represents expenditures that historical carriers who issued CGL policies to WSDOT during the pre-1986 operational window may be obligated both to recover and to fund going forward.

Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.

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 — Coverage and Funding
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim, negotiate and secure insurance coverage. Restorical will manage the ongoing claim process, including accounting to ensure the insurance companies are funding your remediation in a timely manner.
