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.

ARCO Facility No. 5508 operated as a gasoline service station at this Everett address, with releases of petroleum hydrocarbons — including TPHg, benzene, toluene, ethylbenzene, xylenes, and MTBE — detected in groundwater across multiple monitoring wells. Lead contamination documented in wells MW-1 and MW-4 is a direct indicator of historical releases of leaded gasoline, which was phased out of commercial use in the United States prior to 1986. The site is enrolled in the Washington State Voluntary Cleanup Program (VCP #NW2734), with groundwater monitoring spanning at least 2004 through 2016 and monitoring well MW-2 decommissioned in 2005; cleanup work is ongoing. 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 presence of lead in groundwater at this site traces the contamination origin unmistakably to the era of leaded gasoline — operations that predate 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion under Washington law. Those historical carriers remain potentially obligated to address the costs this site has already incurred — years of groundwater monitoring, well decommissioning, and VCP oversight — as well as the ongoing remediation expenditures the long-term groundwater management program will continue to generate.

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.
