Gas Station cleanup site — Restorical Research
Madariaga Chevron Facility
Malheur 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 former retail service station in Malheur County operated petroleum underground storage tanks that were in use well before 1986, with four USTs removed in October 1989 and three additional large-capacity tanks removed in 2009–2010. Petroleum-related soil and groundwater contamination — including the presence of free product — was discovered during the 1989 decommissioning, and sub-slab soil gas sampling in 2010 indicated vapor intrusion concerns. Oregon DEQ has not issued a No Further Action determination for the site, and a Conditional NFA cannot be granted until an Easement and Equitable Servitude is signed and recorded with the county; a Notice of Environmental Contamination was filed as an interim measure in December 2010. 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 underground storage tank operations that were active for years before 1986, with four USTs removed in 1989 and three additional large-capacity tanks removed in 2009–2010. With free product in groundwater, vapor intrusion concerns, and no No Further Action determination yet issued by Oregon DEQ, the investigation, remediation, institutional controls, and compliance costs this property still faces are 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.
