Industrial & Manufacturing cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as an industrial and manufacturing facility going back to 1967. 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 145-acre industrial steel mill in Portland's Rivergate area has operated since 1967 on land with petroleum contamination dating to oil sump pond releases between 1944 and 1961, with additional PCB releases documented in 1982, 1985, and 1991. Multi-media contamination — petroleum hydrocarbons, PCBs, and metals — has been confirmed in soil, groundwater, sediment, and surface water, with riverbank soils sloughing into the Willamette River and the site falling within the Portland Harbor Superfund Site under EPA CERCLA oversight. Oregon DEQ issued a Record of Decision for stormwater source control in December 2010, and shoreline source control received a No Further Action determination in 2017, but the upland risk assessment, feasibility study, and groundwater source control evaluation all remain ahead. 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.

Contamination at this property traces to petroleum releases from oil sump ponds between 1944 and 1961, steel mill operations beginning in 1967, and PCB releases documented in 1982 and 1985 — decades of industrial activity that predated 1986. The cleanup work still ahead — including upland risk assessment, a feasibility study, groundwater source control evaluation, and long-term monitoring under both Oregon DEQ and EPA Superfund oversight — represents costs this property still faces 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.
