Gas Station cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

Seven underground storage tanks were removed from this Richland property between 1992 and 1996, following decades of apparent gasoline dispensing operations. Sampling conducted during and after the tank removals confirmed soil and groundwater contamination exceeding Washington State cleanup levels. The Department of Ecology has encouraged independent cleanup actions at the site, with potential review under the Voluntary Cleanup Program, but no active remediation has commenced. 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.

The underground storage tanks removed from this property were installed and operated well before 1986, the year occurrence-based Commercial General Liability policies stopped reliably covering pollution claims. The petroleum contamination now documented in soil and groundwater is the product of those pre-1986 operations — exactly the kind of long-duration release these policies were written to address. The cleanup costs the property owner faces — site investigation, remedial design, and eventual soil and groundwater remediation — could plausibly be funded by historical carriers whose CGL policies were in effect when those tanks were first put into service.

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.
