Bulk Plant cleanup site — Restorical Research
Colvin Oil Bulk Plant

Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal predating 1986. Historical insurance policies issued during those prior operations and through 1986 could help fund the cleanup that lies ahead.

Colvin Oil Bulk Plant is a bulk fuel distribution facility in Curry County where diesel contamination from an unregulated underground storage tank has impacted multiple environmental media — groundwater, drinking water, surface water, and soil — with free product confirmed at the site. The release was reported to Oregon DEQ in March 1992 following a complaint about piping, and cleanup efforts began shortly thereafter, yet the site has not reached closure after more than three decades. Oregon DEQ executed a Cost Recovery Agreement in May 2025, establishing an active financial obligation on the responsible party and signaling that significant investigation and remediation work remains 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.

Diesel contamination from an unregulated underground storage tank at this bulk fuel plant — a tank type that predates the 1986 RCRA amendments — traces the site's pollution to operations well before 1986, with the release first reported to Oregon DEQ in 1992. With a Cost Recovery Agreement executed in 2025 and contamination — including free product — confirmed in groundwater, drinking water, surface water, and soil, the investigation, remediation, and long-term monitoring costs this property still faces are precisely the type of future obligations that historical pre-1986 carriers may be obligated to fund.

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.
