Industrial & Manufacturing cleanup site — 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 those prior operations and through 1986 could help fund the cleanup that lies ahead.

This industrial property is part of the Northwest Pipe & Casing Superfund Site, listed by EPA in 1992, where pipe-coating operations using coal tar and solvents caused confirmed groundwater contamination. EPA installed and routinely monitors eight groundwater wells on the property, and contamination from an adjacent parcel continues to migrate onto the site. A 1998 consent decree between the previous owner, Oregon DEQ, and EPA established cleanup obligations, followed by Easement and Equitable Servitudes recorded in 2010 that restrict groundwater use and require compliance with investigative and response activities. A Prospective Purchaser Agreement consent order executed in 2021 requires ongoing property maintenance consistent with active remediation, and no No Further Action determination has been issued. 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 groundwater contamination at this property originated from industrial pipe-coating operations using coal tar and solvents confirmed active before 1986, leading to the site's listing on the National Priorities List in 1992 and a 1998 consent decree establishing cleanup obligations with Oregon DEQ and EPA. The investigation, remediation, and long-term monitoring costs this Superfund site still faces — including EPA's ongoing oversight of eight groundwater wells, compliance with institutional controls restricting groundwater use, contamination continuing to migrate from the adjacent parcel, and property maintenance required under a 2021 consent order with no No Further Action determination yet issued — 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.
