Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

During a June 2010 water line installation on Washington State Department of Transportation right-of-way at SR 532 and 96th Drive SE in Stanwood, approximately 140 cubic yards of gasoline-odored soil contaminated with benzene and gasoline range hydrocarbons were excavated and stockpiled for off-site treatment and disposal. The contamination was attributed to an adjacent property formerly occupied by a gas station; excavation was limited to the immediate construction footprint and did not constitute a full site cleanup. As of June 2017, the Department of Ecology has classified the site as Awaiting Cleanup under the Standard Cleanup program. 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.

Benzene and gasoline range hydrocarbons are the signature of underground storage tank releases tied to gas station operations — contamination that accumulates over years, not from a single incident, and that is characteristically traced to facilities operating well before 1986, when occurrence-based Commercial General Liability policies remained standard and carried no effective pollution exclusion. A single construction excavation has already required the removal and off-site disposal of 140 cubic yards of impacted soil, and the broader remediation has not yet begun. Historical CGL carriers whose policies covered the former gas station's operations during that pre-1986 window may be obligated to fund the cleanup costs that still lie ahead.

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.
