Public Works cleanup site — Restorical Research
USAF ANG Portland
Multnomah County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1940. Historical insurance policies issued during operations at this property and through 1986 could help fund the ongoing and future cleanup under Oregon DEQ oversight.

This military installation has been operational since the 1940s, with decades of fire training activities, tank farm operations, and use of aqueous film-forming foam (AFFF) releasing PFAS, petroleum hydrocarbons, solvents, and metals across multiple contamination areas. PFAS compounds — including PFOS, PFOA, and PFHxS — are ubiquitous in groundwater above screening levels, with contamination migrating to the Columbia Slough and McBride Slough via stormwater discharge and groundwater pathways, resulting in a fish consumption advisory after PFOS in fish tissue exceeded Oregon Health Authority thresholds. Oregon DEQ reviewed the Final PFAS Remedial Investigation Report submitted in June 2025 and concluded that additional data collection and interim actions to reduce or eliminate discharge are necessary, with a Risk Assessment and Feasibility Study still 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 originated from military operations, fire training, and fuel storage activities that began in the 1940s — decades before 1986. With Oregon DEQ directing interim actions to reduce PFAS discharge, a Risk Assessment and Feasibility Study still ahead, and the full lateral extent of groundwater contamination not yet defined, the investigation, remediation, and long-term monitoring costs ahead represent a substantial ongoing and future obligation 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.
