Gas Station cleanup site — 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 in Crook County operated with underground storage tanks that released petroleum into the subsurface, with free product discovered near the tanks and groundwater sampling in 1999 confirming ethylbenzene at 500 µg/L and xylenes at 2,700 µg/L in an upgradient monitoring well. Indoor air sampling was conducted at an adjacent residence due to the contamination. Oregon DEQ has noted that the site owner never submitted the final report needed to support a No Further Action determination, and the site remains listed on the state's Confirmed Release List with no closure in sight. 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.

Underground storage tank operations at this gas station property released petroleum into the subsurface well before 1986, contaminating groundwater with elevated levels of ethylbenzene and xylenes confirmed by sampling in 1999. With no final report submitted and no No Further Action determination issued, the investigation and remediation costs this property still faces — including further groundwater delineation, potential free-product recovery, indoor air assessment, and whatever additional work Oregon DEQ may require for closure — represent future obligations that pre-1986 CGL 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.
