Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1922. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

The Ferndale Grain property was contaminated not by its own operations but by petroleum releases from abandoned underground storage tanks at an upgradient former gasoline station at 12631 NE Woodinville Drive — a facility that operated from 1922 through the late 1960s or early 1970s, with as many as three 550-gallon USTs on the source property. Cleanup activities have included removal of two 550-gallon USTs and a 110-gallon oil/water separator, off-site disposal of approximately 18 truckloads of impacted soil, biological treatment using Petrox®, quarterly groundwater monitoring, subsurface investigations, and confirmatory soil sampling. A No Further Action determination is being pursued but has not yet been issued. 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 gasoline station responsible for this contamination operated from 1922 through the late 1960s or early 1970s — decades before 1986, when occurrence-based Commercial General Liability policies were still the industry norm and lacked effective pollution exclusions. Lead analysis was conducted on soil samples specifically because of the age of the tanks and the historical use of leaded gasoline, placing the releases squarely in the pre-1986 era. Historical carriers who issued CGL policies to the station's operators during that long operational window may be obligated both to recover costs already incurred — UST removals, soil excavation, and bioremediation — and to fund the monitoring and remedial work that continues as the site works toward NFA status.

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.
