Gas Station cleanup site — Restorical Research
Circle K 1525
Kent, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1980. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This property has operated as a gasoline service station since approximately 1980, when its underground storage tanks are estimated to have been originally installed. Cleanup under the Voluntary Cleanup Program has included excavation of roughly 10 cubic yards of contaminated soil during product piping replacement in 1998 and 45 cubic yards during UST replacement in 2005, along with monitoring well installation and investigation-derived waste management. Groundwater treatment relies on natural attenuation with ongoing annual monitoring, and the site remains an active service station operating as Circle K 1525 with three fuel USTs and three dispenser islands. 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 detection of lead in soil and groundwater at this site points to leaded gasoline usage — a hallmark of operations predating the mid-1980s, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. Remediation costs already incurred across multiple phases of soil excavation, tank replacement, well installation, and years of groundwater monitoring trace directly to releases from those pre-1986 fueling operations. Historical carriers who issued CGL policies during the station's early operating years may be obligated both to recover past cleanup expenditures and to fund the ongoing monitoring program.

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.
