Gas Station cleanup site — Restorical Research
Crown Hill

Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1950. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property at 8757 Holman Road NW operated as a gasoline service station from the 1950s through the early 1980s, with at least three fuel underground storage tanks, waste oil and heating oil USTs, and four pump islands dispensing gasoline and diesel. Cleanup under the Voluntary Cleanup Program ran from April 2004 through November 2005, encompassing remedial excavation, removal of the USTs along with a hoist and sump, and confirmation sampling to verify cleanup effectiveness. The site received a No Further Action determination in November 2005 and is currently vacant. 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 traces directly to underground storage tank operations that began in the 1950s — more than three decades before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion. The documented remediation costs here — tank removals, hoist and sump extraction, soil excavation, and confirmatory sampling — all stem from those pre-1986 fueling operations. Historical CGL carriers whose policies were in force during the decades of gas station operation at this site may still be obligated to recover those cleanup expenditures.

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.
