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 petroleum fueling facility under BP (Facility No. 11088), now tracked under ConocoPhillips, in Tacoma, Pierce County. Groundwater monitoring at the site dates to at least 2014, with contaminants including Gasoline Range Organics, Diesel Range Organics, BTEX, MTBE, and Non-Aqueous Phase Liquid — all characteristic of long-term fuel storage and dispensing. Total dissolved lead was measured at 7,900 µg/L in monitoring well MW-6 in 1996, more than 500 times the 15 µg/L cleanup level, confirming a release of leaded gasoline from the facility's earlier operations. Remediation through Monitored Natural Attenuation began in 2020 under the Voluntary Cleanup Program, and cleanup work remains 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 dissolved lead at extreme concentrations in groundwater is direct evidence that this facility dispensed leaded gasoline — a product phased out well before 1986, when occurrence-based Commercial General Liability policies still carried no effective pollution exclusion. Decades of documented monitoring, well installation and abandonment, and the current MNA remediation represent substantial cleanup expenditures tied to releases that began during that pre-1986 policy window. Historical carriers who covered the facility's petroleum operations during the leaded-gasoline era may be obligated both to reimburse past remediation costs and to fund the ongoing cleanup.

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.
