Landfill cleanup site — Restorical Research
Old Rossman Landfill - South
Clackamas County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a landfill going back to 1960. Historical insurance policies issued during those prior operations and through 1986 could help fund the cleanup that lies ahead.

This property operated as a landfill from 1960 to 1969, accepting waste on former agricultural land in Clackamas County. Groundwater sampling conducted in 1987, 1989, and 1991 confirmed elevated levels of benzene exceeding primary maximum contaminant levels, along with iron, manganese, metals, volatile and semivolatile organic compounds, pesticides, and PCBs. Oregon DEQ's UST Section referred the site to the Cleanup Program in December 2001 for further investigation of possible diesel impacts to solid waste, and a site assessment recommended additional investigation under the Voluntary Cleanup Program — yet this portion of the landfill has never been directly investigated 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 contamination at this property originated from landfill operations that ran from 1960 to 1969, well before 1986. With the southern portion of the landfill never directly investigated, no No Further Action determination issued by Oregon DEQ, and further assessment recommended under the Voluntary Cleanup Program, the investigation, characterization, and remediation costs that lie ahead are precisely the type of future obligations 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.
