Gas Station cleanup site — Restorical Research
Exxon Keizer
Marion 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.

This gas station property operated as an Exxon fueling station in Marion County, with a release from regulated underground storage tanks discovered in January 1991. Soil and groundwater contamination — including waste oil, gasoline constituents, naphthalene, VOCs, and chlorinated solvents — has been confirmed, with the groundwater plume located less than half a mile from domestic and community wells. Cleanup began shortly after the release was discovered but remains incomplete, and Oregon DEQ has maintained the site under a Cost Recovery Agreement executed in December 2022, with the responsible party under active agreement and the site still open under On Hold status as of early 2025. 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 underground storage tanks at this Marion County property were part of a commercial fueling operation active before 1986, with a release discovered in January 1991 confirming soil and groundwater contamination from those earlier years of service. With remediation still incomplete, a groundwater plume less than half a mile from domestic and community wells, and an active Cost Recovery Agreement with Oregon DEQ, the ongoing investigation, cleanup, and monitoring costs this property still faces may fall to historical carriers that insured operators during the pre-1986 period.

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.
