Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1940. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

The Ernst Ballard Parcel B property at 1401 NW Leary Way hosted an automotive service station with underground storage tanks from at least 1940 through 1970, releasing gasoline, diesel, BTEX compounds, and lead into soil. Remediation under the Voluntary Cleanup Program included in-situ chemical oxidation and bioremediation through injection of oxygen-releasing compounds and nutrient solutions into boreholes and monitoring wells. The site has reached No Further Action status, secured by an environmental covenant that requires a containment cap and semi-annual site inspections. 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 property — including lead attributable to leaded gasoline, which was phased out before 1986 — traces directly to underground storage tank operations active for three decades prior to that cutoff. Occurrence-based CGL policies issued to operators during the 1940–1970 window had no effective pollution exclusion under Washington law and remain enforceable today. The multi-year chemical oxidation program, bioremediation injections, long-term monitoring, and institutional controls all represent documented cleanup expenditures that historical carriers may be obligated to recover.

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.

What We Look For

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.
