Industrial & Manufacturing cleanup site — Restorical Research
Mitchell Brothers Truck Lines

Preliminary Site-Specific Analysis

This property has a documented history as an industrial and manufacturing facility going back to 1914. 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 has hosted continuous commercial and industrial operations since at least 1914, including concrete and steel pipe manufacturing from 1942 and trucking terminal operations from 1965 to 1977. Oregon DEQ issued a Notice of Violation in 1976 for oil-contaminated water discharge onto adjacent properties and into the Columbia Slough, and a Phase II investigation confirmed groundwater contamination — diesel-range organics, benzo(a)pyrene, and arsenic — exceeding risk-based screening levels. Ten underground storage tanks were decommissioned in 1997, but the overall ECSI case remains open under an active Prospective Purchaser Agreement consent order requiring stormwater source control evaluation, implementation of recommended measures, and an $81,000 contribution to the Columbia Slough sediment cleanup fund. 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 commercial and industrial operations dating to at least 1914 — including concrete and steel pipe manufacturing from 1942, trucking terminal operations from 1965 to 1977, and an Oregon DEQ discharge violation in 1976 — all well before 1986. The stormwater source control evaluation, Columbia Slough sediment cleanup fund obligation, and ongoing compliance work required under the active Prospective Purchaser Agreement consent order represent substantial costs this property still faces, and pre-1986 carriers whose policies were in effect during those decades of industrial operations may be obligated to fund that 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.
