Public Works cleanup site — Restorical Research
Sweet Home Work Center
Linn County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could help fund the cleanup that lies ahead.

The U.S. Forest Service Sweet Home Work Center is identified as one of three potential source areas for extensive chlorinated solvent contamination in the Sweet Home Midway neighborhood of Linn County. Two distinct groundwater plumes — a 45-acre PCE/TCE plume and a 5-acre TCA plume — have impacted at least 15 domestic wells at concentrations exceeding safe drinking water levels, prompting 17 households to be connected to the city municipal water supply. Oregon DEQ added the site to its ECSI database in 1999 noting suspected chlorinated solvent sourcing, and no No Further Action determination has been issued; DEQ's remedial action notes state that further investigation is still needed. 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 chlorinated solvent contamination detected in domestic wells in 1992 traces to operations that were underway well before 1986. With no regulatory closure in place and Oregon DEQ's own assessment that further investigation is still needed, the site faces substantial future costs for source delineation, groundwater remediation, and continued monitoring across two separate contaminant plumes — costs that historical pre-1986 carriers may be obligated 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.
