Gas Station cleanup site — Restorical Research
CIRCLE S MARKET
Polk County
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 help fund the cleanup that lies ahead.

Circle S Market in Polk County operated as a gas station with underground storage tanks that were decommissioned in October 2024, at which time petroleum contamination was discovered. Diesel, unleaded gasoline, BTEX compounds, naphthalene, and arsenic have been confirmed in both soil and groundwater, with the aquifer located less than 20 feet below the surface and vapor intrusion identified as a possible concern. The site is under agreement with Oregon DEQ and subject to risk-based corrective action, but remains in early stages with no remediation completed and no No Further Action determination issued. That history could support an insurance coverage claim against the carriers who issued policies more than 40 years ago — coverage that could help fund the cleanup ahead.

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 Oregon — and those policies may provide coverage that remains enforceable today. 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 contamination released from underground storage tanks at this property traces to gas station operations that were underway before 1986 and continued until the tanks were decommissioned in October 2024, with diesel, unleaded gasoline, BTEX compounds, naphthalene, and arsenic confirmed in both soil and groundwater less than twenty feet below the surface. The investigation, remediation, and monitoring costs this property still faces — including groundwater delineation, vapor intrusion assessment, and risk-based corrective action under Oregon DEQ oversight — represent future obligations that historical pre-1986 carriers may be obligated to fund.

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 viable insurance coverage exists to fund the cleanup, 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.
