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 — and recover costs already spent.

This property operated as a Circle K fueling station with underground storage tanks that were removed in 1994. The site received a No Further Action determination in 1995, but that status was rescinded in 2017 after new soil sampling confirmed gasoline and motor oil contamination above cleanup levels. The site is now enrolled in the Voluntary Cleanup Program with cleanup underway. 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 gasoline and motor oil contamination at this property originated from underground storage tanks operated well before 1986 — lead detected alongside gasoline in soil samples points to the leaded-fuel era, and the tanks' lifecycle is consistent with installation in the late 1960s or earlier. Occurrence-based CGL policies in force during that pre-1986 operating window carried no effective pollution exclusion in Washington. The remediation costs already incurred and the cleanup work still ahead represent expenditures that the historical carriers who covered those operations may be 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.
