Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1941. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

The Pasco Bulk Fuel Terminal Site has operated as a petroleum storage and distribution facility since at least 1941, when the first lease agreements were established, with a main tank farm and several smaller farms supplying gasoline, diesel, and agricultural chemicals via railcar, truck, barge, and pipeline. A petroleum release problem was identified as early as 1973, and remediation has been underway continuously since 1992 — spanning more than 33 years and millions of dollars in expenditures. Active cleanup included dewatering wells, interceptor drains, oil/water separators, early product recovery of at least 5,000 gallons, In-Situ Air Sparging, Soil Vapor Extraction (approximately 58,000 pounds of TPH removed), and pump-and-treat systems; the site is now in a Monitored Natural Attenuation phase with ongoing groundwater and surface water monitoring, institutional controls, and long-term operation and maintenance. The tank farms remain in active commercial operation today. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.

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 Washington. 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.

Petroleum contamination at this site traces directly to bulk fuel storage and distribution operations that began in 1941 — more than four decades before the 1986 watershed year when occurrence-based Commercial General Liability policies effectively lost their pollution coverage. Monitoring wells installed in late 1986 and early 1987 confirm that regulators were already responding to contamination from pre-1986 operations, establishing a clear chain of liability back to that era. The scale of documented remediation here — 33-plus years of active cleanup, tens of thousands of pounds of hydrocarbons extracted, and ongoing monitoring and institutional controls — represents precisely the kind of long-tail environmental liability that historical CGL carriers may remain 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 a successful cost recovery is possible, 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.
