Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1982. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This Bellevue 7-Eleven has operated as a convenience store and retail gasoline station since at least 1982, when its three 12,000-gallon single-wall steel underground storage tanks were installed. In 1986, approximately 3,200 gallons of unleaded gasoline were released from that UST system, triggering a cleanup effort that has included multiple phases of soil excavation totaling over 116 cubic yards, high-vacuum groundwater extraction recovering 5,100 gallons of affected water, free-product recovery of 70 pounds, nutrient injections, and an air sparging and soil vapor extraction system that operated intermittently from 1995 until its removal in 2015. Groundwater monitoring remains 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 1986 gasoline release at this property originated from a UST system that had been in the ground since 1982 — a period when occurrence-based Commercial General Liability policies were still the industry standard and Washington's pollution exclusion was not reliably enforceable. The contamination event itself falls precisely at the pre-1986 policy threshold, meaning carriers who issued CGL coverage to the site's operators in the years leading up to and including 1986 may still bear obligations tied to that release. Decades of documented remediation expenditures — excavation, groundwater recovery, vapor extraction, and long-term monitoring that continues today — represent costs that historical carriers may be obligated both to recover and to fund going forward.

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.
