Gas Station cleanup site — Restorical Research
AMLI Ballard Property

Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1937. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property on NW Market Street in Seattle's Ballard neighborhood has been in continuous commercial use since at least the late 1930s, when the original 1927-era building began operating as an automotive service garage and retail gasoline station. Heating oil underground storage tanks were installed pre-1986 and removed in 1995, and three additional USTs were discovered during a 2012 redevelopment of the property. The site was enrolled in the Voluntary Cleanup Program, benzene was confirmed in groundwater during investigation, and the property received a No Further Action determination in December 2015. 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.

Retail gasoline sales and heating oil storage at this property began decades before 1986, placing the operations squarely within the era of occurrence-based Commercial General Liability policies that carried no effective pollution exclusion. The UST infrastructure installed during that pre-1986 window — including tanks that remained buried until the 2012 redevelopment — and the benzene contamination documented in site groundwater underscore the environmental liabilities tied to those operations. Historical carriers who provided CGL coverage during the 1930s-through-1980s operational period may be obligated to reimburse the investigation, UST removal, and remediation costs incurred to bring the property to its No Further Action status.

Restorical's role is to locate viable historical policies, determine whether a successful cost recovery claim is possible, and assist our clients and their legal counsel to obtain insurance coverage for costs already incurred. Restorical's forensic accounting team works to re-establish and document past cleanup expenditures, ensuring the strongest possible basis for recovery.

Recovering Costs from an Older Cleanup

If this site reached No Further Action years ago, the original cleanup expenditures may be difficult to reconstruct. Restorical's forensic accounting team specializes in re-establishing and documenting past cleanup costs — even decades later — to build the strongest possible basis for an insurance recovery claim.

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 — Cost Recovery
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim and negotiate recovery of costs already incurred. Restorical's forensic accounting team re-establishes and documents past cleanup expenditures, managing the claim process to ensure the insurance companies fulfill their obligation in a timely manner.
