Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal predating 1986. Historical insurance policies issued during operations at this property and through 1986 could help fund the ongoing and future cleanup under Oregon DEQ oversight.

This bulk petroleum distribution terminal in Multnomah County has been the subject of remedial investigations since the 1970s, with contamination originating from inland spills, burial of tank bottoms, and leaky petroleum transmission lines across the Chevron, Shell, and Unocal facilities. Free product and dissolved-phase petroleum contamination persist in groundwater, heavy metals including arsenic and manganese exceed Portland Harbor ROD cleanup levels, and petroleum seepage into the Willamette River has been documented. A 1994 Consent Order between Oregon DEQ and the three operators requires remedial investigation, feasibility study, and interim remedial measures, and active remediation continues today — including semi-annual groundwater monitoring, quarterly separate-phase hydrocarbon recovery, and groundwater extraction and treatment system operation. 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 terminal complex traces to petroleum distribution operations and disposal practices — including inland spills, burial of tank bottoms, and leaking transmission lines — that were well underway by the 1970s, decades before 1986. With Portland Harbor ROD cleanup levels still being exceeded for arsenic and manganese and petroleum contamination persisting in groundwater, the ongoing and future remediation obligations under the 1994 Consent Order — including continued groundwater extraction and treatment, separate-phase hydrocarbon recovery, and long-term monitoring — represent substantial costs that pre-1986 CGL carriers whose policies were in effect during those operational years may be obligated to fund 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.
