Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1938. 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 gasoline station since 1938, with underground storage tanks installed well before 1986 and decommissioned in 1991. Petroleum contamination was discovered during UST decommissioning, and subsequent investigations between 1997 and 2001 revealed chlorinated solvents — tetrachloroethylene (PCE), trichloroethylene (TCE), and cis-1,2-dichloroethylene — in groundwater, with the PCE plume extending off-site into the Trade Street right-of-way and neighboring properties. PCE concentrations exceed hot-spot screening values for residential vapor intrusion, and contaminated shallow groundwater threatens a deeper water-bearing zone used for drinking water. The site is assigned to an Oregon DEQ project manager, but no remediation has been completed and additional investigation is still needed to determine the full extent of contamination and identify current risks to human health. 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 originates from gasoline station operations and vehicle service activities that began in 1938 — nearly five decades before 1986 — with underground storage tanks that remained in service until their decommissioning in 1991. The investigation and remediation that Oregon DEQ has determined is still needed — including fully characterizing the off-site PCE plume, assessing vapor intrusion risks, and protecting the deeper drinking water supply — represents substantial future costs this property still faces, and historical pre-1986 carriers may be obligated to fund that work.

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.
