Gas Station cleanup site — Restorical Research
UHaul Pacific Hwy S

Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1964. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property was previously operated as a gasoline service station, with the main building constructed in 1964. In February 1990, six to eight underground storage tanks, fuel dispensers, and associated piping were removed from the site, and contaminated soil was discovered during that work — 830 cubic yards of impacted soil were excavated. Groundwater remediation has been ongoing since 1990 and has included installation of monitoring and vapor extraction wells, free product removal through pumping and bailing, passive skimmers, and continuous groundwater monitoring. 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.

Petroleum contamination at this property originated from underground storage tanks that served a gas station operating from at least the mid-1960s — more than two decades before 1986, when occurrence-based CGL policies still carried no effective pollution exclusion in Washington. The site's remediation costs — tank removal, large-scale soil excavation, vapor extraction, free product recovery, and over three decades of groundwater monitoring — represent expenditures the historical carriers who issued policies during that pre-1986 operational window may be obligated both to reimburse and to fund as cleanup continues.

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.
