Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1976. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This property has served as the Marysville School District's bus maintenance and fueling facility, with four underground storage tanks installed on December 1, 1976, to support vehicle fueling operations. Contamination from leaking USTs was discovered in 1997, and cleanup under the Standard Cleanup program began in February 1998. Remediation has included the removal of all four USTs and two fuel dispensers, along with a petroleum-contaminated soil removal action in March 2016 that excavated 66.11 tons of impacted soil for thermal desorption and landfilling. The facility continues to operate as a vehicle fueling site for the school district. 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 that caused the petroleum contamination at this site were installed in 1976 — a decade before occurrence-based Commercial General Liability policies gave way to claims-made forms with absolute pollution exclusions. CGL policies issued to the Marysville School District during that pre-1986 operational window had no effective pollution exclusion under Washington law and remain potentially enforceable. Nearly two decades of documented remediation expenditures — tank removals, soil excavation, thermal treatment, and ongoing cleanup — represent costs that historical carriers 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.
