Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1924. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property was first developed as a fuel supply point in 1924, initially using aboveground storage tanks, and was redeveloped with underground storage tanks in 1939. It operated as a gasoline service station until the mid-1980s. Cleanup under the Standard Cleanup program included demolition of site structures, removal of four underground storage tanks, and excavation of 2,153 tons of contaminated soil in 2005, followed by backfill, installation of a multi-layered cap, and placement of a Restrictive Covenant with ongoing periodic reviews and monitoring. 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 originated from fuel storage and dispensing operations that began more than six decades before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion. The documented remediation expenditures — tank removals, demolition, excavation of over two thousand tons of soil, engineered capping, and continuing long-term monitoring — were incurred to address releases tied directly to those pre-1986 operations. Historical carriers who issued CGL policies during any portion of the 1924-to-mid-1980s operational window may be obligated both to recover past cleanup costs and to fund the site's ongoing monitoring obligations.

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.
