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 1905. Historical insurance policies issued during those prior operations and through 1986 could help fund the ongoing and future cleanup under Oregon DEQ oversight.

This 26-acre former railroad switching and fueling yard in Portland's Pearl District operated from approximately 1905 to 1998, with a fueling area active from 1911 through the mid-1940s that left petroleum concentrations as high as 29,000 ppm in subsurface soils. Petroleum contamination was first observed at the Tanner Creek outfall in the 1970s, and free-product recovery from groundwater began in December 1975 — well before the site was added to Oregon's Confirmed Release List in 1991. Oregon DEQ issued an Order on Consent in 1995 and a Consent Decree was recorded in 2002, and the ROD has been amended three times, most recently in September 2025 extending the cleanup deadline to 2035. Remaining work includes capping undeveloped blocks north of Quimby and Raleigh, filing deed restrictions on remaining parcels, and conducting annual cap inspection reporting. 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 — petroleum hydrocarbons, PAHs, lead, and vinyl chloride — traces directly to railroad fueling operations active from 1911 through the mid-1940s within a switching yard that operated from approximately 1905 to 1998, with petroleum contamination first observed at the Tanner Creek outfall in the 1970s and free-product recovery underway by December 1975, well before 1986. The work ahead under the Consent Decree and Order on Consent — capping undeveloped blocks north of Quimby and Raleigh, filing deed restrictions on remaining parcels, cap maintenance, and annual cap inspection reporting through the 2035 ROD deadline — represents substantial future costs that historical pre-1986 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.
