Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1928. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property includes a former service station on Parcel NL-182 that operated from the late 1920s through 1950, leaving behind substantial petroleum contamination that has driven extensive remediation. Cleanup activities have included multiple rounds of petroleum contaminated soil (PCS) excavation — the largest single removal was approximately 2,390 cubic yards associated with the former station, with additional removals of 26, 188, and 100 cubic yards — along with groundwater management by dewatering and vacuum truck, hazardous building materials abatement, and installation of physical barriers including shot-crete and a deep station tunnel. Gasoline-range hydrocarbons (TPH-G) and BTEX compounds were detected at concentrations exceeding MTCA Method A cleanup levels, 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 petroleum contamination at this property traces directly to a service station that operated from the late 1920s to 1950 — more than three decades before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion in Washington. The scale of documented remediation here — multiple large-volume soil excavation campaigns, groundwater extraction, and structural mitigation measures — represents substantial costs attributable to those pre-1986 operations. Historical carriers whose policies were in effect during the decades of active service station use may be obligated both to recover past cleanup expenditures and to fund the remediation that remains ongoing.

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.
