Public Works cleanup site — Restorical Research
WILLAMETTE RESEARCH STATION

Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1972. Historical insurance policies issued during those prior operations and through 1986 could help fund the ongoing and future cleanup under Oregon DEQ oversight.

This property was licensed for agricultural use beginning in 1964 and developed in 1972 as an EPA environmental research laboratory, with six manmade research ponds added in the late 1970s. A Phase 1 Environmental Site Assessment completed in October 2025 identified recognized environmental conditions, including hazardous building materials (asbestos and lead) from the original 1972 construction and contaminated sediments in the research ponds dating to 1970s operations. The site is at the earliest stage of investigation under Oregon DEQ oversight as an assigned cleanup project, with no remediation yet undertaken and all cleanup work ahead. 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 facility construction in 1972 and research pond operations conducted through the late 1970s, well before 1986. With the site at the earliest investigation stage under Oregon DEQ oversight and all delineation, remediation, and monitoring costs still ahead, historical pre-1986 policies issued to operators of this facility may be obligated to fund the substantial cleanup work this property still faces.

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.
