Bulk Plant cleanup site — Restorical Research
Shell Oil Co. - Willbridge Plant
Multnomah County

Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1938. 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 fuel terminal in Multnomah County has been in industrial use since at least 1938, with Shell Oil, Chevron, and Union Oil among its historical operators and Kinder Morgan continuing operations today. Petroleum hydrocarbon releases from decades of terminal operations have resulted in separate-phase hydrocarbons in groundwater, with contamination migrating to the Willamette River through groundwater discharge, bank soil erosion, and stormwater pathways via Saltzman Creek. Oregon DEQ entered a Consent Order with Shell Oil, Chevron, and Union Oil in 1994, and the site falls within the Portland Harbor Superfund Site under an EPA Record of Decision issued in 2017. A 2022 work plan for bank soil removal has been prepared but the removal itself has not yet been executed, and the site remains under active DEQ oversight with source control evaluation ongoing under the Portland Harbor Joint Source Control Strategy. 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.

Bulk petroleum terminal operations at this property were established by at least 1938 and continued for decades before 1986, releasing petroleum hydrocarbons that have resulted in separate-phase contamination in groundwater and contaminant migration to the Willamette River. The cleanup costs this property still faces — executing the planned bank soil removal along the Willamette River, ongoing groundwater monitoring and source control evaluation under both the Oregon DEQ Consent Order and the EPA Superfund framework, and whatever additional remediation the Joint Source Control Strategy directs — are obligations that historical pre-1986 carriers may be required 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.
