Gas Station cleanup site — Restorical Research
City of McMinnville
Yamhill 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 operations at this property and through 1986 could help fund the ongoing and future cleanup under Oregon DEQ oversight.

This municipal property operated underground storage tanks containing leaded gasoline — a fuel phased out for road use by the mid-1980s — indicating decades of tank operations predating 1986. When the regulated UST was decommissioned in 2008, petroleum contamination was confirmed in both soil and groundwater, with lead identified as an additional contaminant of concern and the groundwater plume documented in a shallow aquifer less than twenty feet deep. Oregon DEQ has assigned the site an active project manager and a Cost Recovery Agreement filed in October 2023 establishes an ongoing financial obligation, with 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 contamination at this property traces to leaded gasoline storage tank operations that were necessarily underway before 1986, as the fuel was phased out for road use by the mid-1980s and petroleum contamination — with lead identified as an additional contaminant of concern — was confirmed in soil and groundwater when the regulated tank was decommissioned in 2008. The ongoing investigation and remediation under active Oregon DEQ project management, formalized by the October 2023 Cost Recovery Agreement with no No Further Action determination yet issued, represents substantial current and future costs that historical pre-1986 carriers whose policies were in effect during those operational years may be obligated 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 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.
