Gas Station cleanup site — Restorical Research
Key Bank McAbee Property
9735 Holman Rd NW, Seattle, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1956. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

A gasoline service station operated at this property from 1956 until 1984, when its underground storage tanks were removed. Cleanup activities have included drumming and temporary storage of petroleum-contaminated soil cuttings and rinsate water for off-site disposal, and installation of a sub-slab vapor monitoring probe. A Voluntary Cleanup Program project was active from approximately 2008 through 2018, when Ecology terminated it due to inactivity; quarterly groundwater monitoring had been planned as part of that effort. The property now hosts the Key Bank Building, constructed on the footprint of the former service station. 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 hydrocarbon contamination at this site traces directly to underground storage tanks installed and operated from 1956 through 1984 — three decades of pre-1986 operations conducted when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The documented remediation trail — UST removal, impacted-soil handling, vapor monitoring, and planned groundwater monitoring — represents expenditures attributable to those historical operations. Historical carriers who issued CGL policies to the service station operator during the 1956–1984 window may be obligated both to recover costs already incurred and to fund the cleanup work that remains unresolved.

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.
