Restorical Research
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 the U-Save service station, dispensing gasoline and diesel through underground storage tanks and fuel dispensers at 20717 Bothell Everett Highway. Groundwater monitoring records for the site date to March 1998, with investigations confirming TPH-G and BTEX contamination consistent with long-standing UST releases. Remediation under the Voluntary Cleanup Program has included a Soil Vapor Extraction system that removed 2,076 pounds of hydrocarbons, an Air Sparge system, aqueous sulfate injection, and carbon-based in-situ injections using PlumeStop® and ORC Advanced®, with multi-year quarterly groundwater monitoring continuing. 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 hydrocarbon contamination at this former service station — TPH-G and BTEX from underground gasoline and diesel storage — originated from operations that predated 1986, when occurrence-based CGL policies were standard and carried no effective pollution exclusion in Washington. The documented remediation record here — vapor extraction, air sparging, chemical injection, and sustained groundwater monitoring — represents a substantial cost trail tied directly to those pre-1986 UST releases. Historical carriers who issued CGL coverage to U-Save Oil Company during that operational window may be obligated to recover those past expenditures and to fund cleanup work that remains ongoing.

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.
