Industrial & Manufacturing cleanup site — Restorical Research
East Side Plating - Plant 4
Multnomah County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as an industrial and manufacturing facility 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 industrial property has housed metal plating operations since before 1986, with city enforcement actions against hazardous discharges — including acids and cyanide — dating to 1979 and a corroded sewer pipe replacement in 1980. Tetrachloroethylene (PCE) and trichloroethylene (TCE) from decades of plating operations have been confirmed in groundwater, soil gas hot spots have been documented, and indoor air sampling has identified TCE vapor intrusion exceeding risk-based concentrations. PFOS and PFOA have also been detected above EPA maximum contaminant levels in multiple monitoring wells. Oregon DEQ's March 2025 response letter directs a substantial slate of additional work — short-term vapor intrusion protective measures, a potential interim remedial action work plan, new monitoring well installation, spring groundwater sampling, additional vapor point installation, and a PFAS assessment — and no remediation has yet begun. 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 decades of industrial plating operations that were already prompting city enforcement action against hazardous discharges — including acids and cyanide — by 1979, well before 1986. The investigation, remediation, and long-term monitoring costs this property still faces are substantial — Oregon DEQ's March 2025 response letter directs vapor intrusion protective measures, a potential interim remedial action work plan, new monitoring well installation, additional vapor point installation, and a PFAS assessment — and pre-1986 carriers whose policies were in effect during those decades of plating operations may be obligated to fund this work 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.
