Gas Station cleanup site — Restorical Research

Tacoma, Pierce County

Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1968. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

This Tacoma property has been in operation since at least 1968 and held multiple underground storage tanks used for fuel storage and dispensing. Three of those USTs were removed in 1989, but petroleum contamination — gasoline, benzene, ethyl benzene, xylenes, and heavy oil — remains in both soil and groundwater at concentrations above MTCA Method A cleanup levels. The site is currently listed as awaiting further cleanup under Washington's Standard Cleanup program, with no active remediation yet underway. 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 underground storage tanks at this property were installed and in service well before 1986, the year after which occurrence-based Commercial General Liability policies began incorporating effective pollution exclusions. The slow subsurface migration of petroleum hydrocarbons — the contamination mechanism documented here — is exactly the continuing-release scenario those pre-1986 policies were written to address. With cleanup yet to begin in earnest, the costs ahead — site design, active soil and groundwater treatment, long-term monitoring — could plausibly be funded by historical carriers whose policies were in force when the contamination first originated from those tanks.

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.
