Gas Station cleanup site — Restorical Research
Truax Shell #19
Benton County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1957. Historical insurance policies issued during those prior operations and through 1986 could help fund the ongoing and future cleanup under Oregon DEQ oversight.

This property operated as a service station from 1957 to 1989, with underground storage tanks removed in 1992 after more than three decades of fueling operations. Groundwater sampling has confirmed BTEX compounds and naphthalene exceeding risk-based concentrations at multiple locations, including offsite migration into NW 29th Street. Oregon DEQ has the site under active oversight as an assigned Risk-Based Corrective Action project with a Cost Recovery Agreement executed in 2022, and no No Further Action determination has been issued as the site remains in the assessment phase with offsite delineation still required. 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 at this property originated from service station operations that began in 1957 and continued for nearly three decades before 1986, with underground storage tanks remaining in use until their removal in 1992. The ongoing assessment, offsite groundwater delineation, and future remediation work directed under Oregon DEQ's Cost Recovery Agreement represent substantial costs this property still faces, and pre-1986 carriers whose policies were in effect during those operational years may be obligated to fund that work 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.
