Industrial & Manufacturing cleanup site — Restorical Research
Hyperion Environmental LLLP I (NE 87th)

Preliminary Site-Specific Analysis

This property has a documented history as an industrial and manufacturing facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could help fund the ongoing and future cleanup under Oregon DEQ oversight.

This industrial property operated as a chlorinated solvent distribution center prior to 1972 under Ethyl Corp, then was acquired by Purex Industries in 1972 for solvent recycling, distribution, storage, and resource recovery — with ownership passing to Allied Signal by the mid-1980s. Decades of solvent handling produced a 5,400-foot chlorinated solvent plume of tetrachloroethylene (PCE) and trichloroethylene (TCE) contaminating the Unconsolidated Gravel and Troutdale Gravel Aquifers, both designated drinking water sources near Portland's backup wellfield. Oregon DEQ issued a Consent Order effective June 2000, and the site is now under active remediation with a long-term groundwater pump-and-treat system, air stripper, soil vapor extraction, and groundwater circulation wells — with an estimated $7.2 million cleanup cost over a fifteen-year period. 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.

Chlorinated solvent distribution at this property began prior to 1972 and continued through solvent recycling, storage, and resource recovery operations that were well established before 1986. The ongoing pump-and-treat remediation, air stripping, soil vapor extraction, groundwater circulation, and long-term aquifer monitoring directed under the Oregon DEQ Consent Order represent an estimated $7.2 million in 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.
