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 industrial property along the Willamette River hosted continuous heavy industrial operations from 1905 through the late 1970s, including lumber milling, woolen manufacturing, marine ironworks, and plywood production. When the buildings were razed in the late 1970s, an estimated 500–600 tons of sandblasting waste from marine tank cleaning were placed as fill along the riverbank, introducing PCBs, dioxins and furans, PAHs, pesticides, and metals into soil and sediment. Oregon DEQ executed a Consent Order in March 2021 directing the responsible parties to design and construct an engineered riverbank source control measure; the 60% Design Report was completed in June 2025, with the 90% design anticipated in early 2026 and removal of contaminated riverbank soils expected to begin in late summer 2026. 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 originated from continuous industrial operations — including lumber milling, woolen manufacturing, marine ironworks, and plywood production — that spanned from 1905 through the late 1970s, entirely before 1986. The engineered riverbank construction, contaminated soil removal, groundwater pathway evaluation, and long-term monitoring directed by Oregon DEQ's Consent Order represent substantial ongoing and future cost obligations that historical pre-1986 carriers 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.
