Gas Station cleanup site — Restorical Research

Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1971. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property was developed as a gas station in 1971, with underground storage tanks installed that same year — following roughly three decades of prior use as the Pullman Junk Company scrap yard. At least one of the original 1971 tanks leaked, and all original USTs were replaced in 2002. Under the Voluntary Cleanup Program, a pump-and-treat system was installed in 2013 and has treated approximately 279,137 gallons of petroleum-contaminated groundwater, with ongoing monitoring for BTEX and other petroleum hydrocarbons. 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 underground storage tanks installed in 1971 — fifteen years before the 1986 shift away from occurrence-based CGL policies. The documented remediation costs — tank replacements, a pump-and-treat system, and years of groundwater monitoring — were incurred to address releases tied directly to those pre-1986 operations. Historical carriers who issued CGL policies during the 1971-and-forward operational window may still be obligated to recover past cleanup expenditures and fund the remediation work that remains.

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.
