Gas Station cleanup site — Restorical Research
Zimmermans Shell

Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1930. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property has operated as a retail fueling station since the 1930s, with the current building and pump locations established by the mid-1940s. Ed and Boyd Zimmerman operated the station from 1954 until 1992, when it was sold to Stephen Burks; above-ground storage tanks supplied the fuel pumps until 1994, and Ecology UST records document multiple tanks installed in 1964 specifically to store leaded gasoline. Cleanup under the Voluntary Cleanup Program has been ongoing since at least 1991, encompassing multiple UST and soil excavation events (approximately 900 cubic yards removed), off-site treatment of excavated material, and pumping and treatment of petroleum-affected water from an on-site trench system. 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.

Contamination at this site — petroleum hydrocarbons and lead from decades of leaded-gasoline dispensing — traces to operations predating 1986 by more than half a century. Ecology UST records confirm tanks installed in 1964 for leaded gasoline, and pre-World War II underground tanks were recovered during later excavations, establishing a contamination origin firmly within the era when occurrence-based CGL policies carried no effective pollution exclusion in Washington. The documented remediation expenditures — UST removals, soil excavation and off-site treatment, groundwater recovery — represent costs that historical carriers may be obligated both to recover 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.
