Gas Station cleanup site — Restorical Research
Omak Gull 611
Omak, Okanogan 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 — and recover costs already spent.

This property operated as Gull Service Station No. 611, a retail gasoline station equipped with three single-walled underground storage tanks totaling 32,000 gallons of capacity — dispensing unleaded, mid-grade, and premium unleaded gasoline from two pump islands. A gasoline fuel release was discovered in September 1997, prompting cleanup under the Voluntary Cleanup Program that has included removal of all three USTs and associated piping, excavation of hydrocarbon-impacted soils and exploratory test pits, and a multi-year groundwater monitoring program in place since 1997. The service station is now closed and cleanup work is 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 gasoline contamination at this property originated from underground storage tanks that were in service well before 1986 — lead detected in soil and groundwater samples is consistent with leaded gasoline sales typical of that era. Occurrence-based CGL policies issued to the station's operators during those pre-1986 years carried no effective pollution exclusion under Washington law and remain enforceable today. The documented remediation expenditures — tank removals, soil excavation, and decades of groundwater monitoring — along with further cleanup efforts still planned represent costs that historical carriers may be obligated both to recover and to fund going forward.

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.
