Gas Station cleanup site — Restorical Research
Harmon & Associates
Everett, Snohomish County

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 — and recover costs already spent.

This property operated as a gasoline service station with multiple underground storage tanks holding gasoline, distillate-derived fuels, and waste oil, along with a large marine-style waste oil buoy. Cleanup activities have included extensive excavation and re-excavation of petroleum and waste oil impacted soils, removal of the underground storage tanks and the waste oil buoy, pumping of contaminated liquids from sumps and catch basins, and deployment of absorbent pads to control oil sheens in excavations and a detention pond. Tank removal was documented in February 1990, and remediation under the Standard Cleanup program is ongoing. 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 petroleum and waste oil contamination at this site originates from underground storage tank operations that, based on the physical evidence of tanks removed in 1990, were in place well before 1986 — the year occurrence-based CGL policies began routinely excluding pollution claims. Carriers who issued those policies to the service station operator during the pre-1986 window had no effective pollution exclusion under Washington law and remain potentially obligated on those coverage obligations today. The remediation expenditures documented here — soil excavation, UST removal, sump pumping, and ongoing contamination management — represent costs that historical insurers may be required both to recover and to fund as cleanup continues.

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.
