Gas Station cleanup site — Restorical Research
Tacoma City Convention Ctr Garage
Tacoma, Pierce County
Restorical Research
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.

This property operated as a paved surface consistent with fuel dispensing and automotive service use for many decades before the Tacoma City Convention Center Garage was constructed on the site in 2001. In January 2005, the City of Tacoma notified Ecology that sampling of the garage's footing drains revealed contaminated groundwater containing gasoline, oil, tetrachloroethylene (PCE), and a petroleum-based engine assembly lubricant matching a specific commercial product. The contamination source remains undefined; current measures consist of a footing drain system that captures and reroutes affected groundwater, with the garage's impervious cover serving as an overlying cap. Active remediation has not yet commenced. 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 mixture of gasoline, oil, PCE, and specialized lubricants found in the groundwater here is characteristic of automotive service operations that, based on the site's documented pavement history, were underway at this location well before 1986. The contamination source is undefined and the remediation scope has not yet been established — meaning the property owner faces investigation and cleanup expenditures whose full extent remains unknown. Pre-1986 occurrence-based CGL policies issued to operators of the earlier service station could plausibly be called upon to fund that upcoming work, rather than leaving the current owner to absorb costs tied to a release that predates their tenure entirely.

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.
