Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as a bulk petroleum fuel farm near Seattle-Tacoma International Airport, with underground storage tanks, a pipeline fuel metering station, and Jet A fuel distribution infrastructure that was in use and causing contamination prior to 1986. Environmental investigations conducted from 1988 through 2010 delineated petroleum hydrocarbon-impacted soil and groundwater, including Jet A fuel free product. Remediation has included tank and soil removal, product extraction, bioventing, and a dual-phase extraction system that recovered over 43,000 pounds of petroleum hydrocarbons; groundwater and soil monitoring, product bailing, and institutional controls remain ongoing, with future DPE operation costs estimated at up to $250,000. 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 contamination at this former fuel farm traces to bulk petroleum storage and distribution operations that were underway before 1986 — the last years in which occurrence-based Commercial General Liability policies were written without effective pollution exclusions in Washington. The documented remediation record here is substantial: tank removals, soil excavation, bioventing, years of dual-phase extraction recovering tens of thousands of pounds of hydrocarbons, and continuing monitoring and product bailing. With up to $250,000 in projected future DPE costs still ahead, historical carriers who issued CGL policies during the fuel farm's operational window may be obligated both to recover cleanup expenditures already incurred and to fund the remediation that remains.

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.
