Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station predating 1986. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

Food Mart 2470 operates as an active retail fueling station at 5235 Delridge Way SW, with a convenience store, a pump island canopy serving two product dispensers, and three 10,000-gallon underground storage tanks containing gasoline. Petroleum hydrocarbons — TPH-G, TPH-D, and benzene — have been detected in soil and groundwater concentrated around the dispenser islands and USTs, and lead was identified in soil during a 2007 baseline assessment. Quarterly groundwater monitoring has been ongoing since September 2016, and a Dual-Phase Extraction system with remedial extraction wells was installed in September 2019, with operations to commence upon electrical service completion. 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 detection of lead in soil at this site is a direct indicator that the fueling operation dispensed leaded gasoline — a product phased out before 1986 — placing the contamination-generating activity within the era of occurrence-based Commercial General Liability policies that carried no effective pollution exclusion in Washington. The documented petroleum contamination from USTs and dispenser islands, now the subject of active DPE remediation and long-running groundwater monitoring, represents both historical cleanup expenditures and forward-looking remediation costs that carriers who issued CGL policies during the leaded-fuel era 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.
