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.

A Hudson Oil retail gasoline station formerly operated at this property, with underground storage tanks decommissioned and removed in 1985. Subsequent investigation confirmed petroleum contamination in soil and groundwater, prompting enrollment in the PLIA Petroleum Technical Assistance Program for cleanup under MTCA. Remediation work to date includes the installation of three permanent groundwater monitoring wells in 2018, a preliminary vapor intrusion assessment, and plans for three additional monitoring wells and temporary soil-gas probes to guide the next phase of cleanup. 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 petroleum contamination at this property traces directly to underground storage tank operations that predated 1986 — the year occurrence-based Commercial General Liability policies began incorporating effective pollution exclusions. CGL policies issued to Hudson Oil or the property's operators during that pre-1986 operational window were written on an occurrence basis with no enforceable pollution exclusion under Washington law. The documented and anticipated remediation expenditures here — UST removal, groundwater monitoring, vapor intrusion investigation, and the ongoing assessment required under MTCA — represent costs the historical carriers may be obligated both to recover and to fund going forward.

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.
