Industrial & Manufacturing cleanup site — Restorical Research
The Irwin Hodson Company
Multnomah County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as an industrial and manufacturing facility going back to 1965. 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 industrial property has housed manufacturing operations since at least the early 1900s — including a foundry, spray-painting booth, and heat-treating room — and has operated as a metal sign and printing facility since the mid-1960s. Trichloroethylene (TCE), consistent with decades of industrial solvent use, has been detected above Oregon DEQ occupational Risk-Based Concentrations in sub-slab vapor and indoor air, confirming active vapor intrusion, with groundwater also impacted. The site is enrolled in Oregon's Voluntary Cleanup Program under DEQ oversight with approved workplans, and as of 2023 DEQ is proposing next steps for active remediation of TCE sub-slab vapor hot spots — with investigation and remediation planning still underway. 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.

TCE contamination at this property traces to industrial manufacturing operations — including foundry work, spray painting, and solvent use — conducted at the site from the early 1900s through decades before 1986. The vapor intrusion remediation, active treatment of sub-slab TCE hot spots, continued groundwater investigation, and long-term monitoring still ahead under Oregon DEQ oversight represent substantial future cleanup costs 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.
