Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1968. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property served as the United States Postal Service's Queen Anne Station, with a 10,000-gallon underground storage tank used for heating fuel storage installed no later than the 1960s. Cleanup under the Voluntary Cleanup Program included in-place closure of the UST, removal of approximately 3 cubic yards of petroleum-contaminated soil, pumping of petroleum-sheened water from the excavation, draining of product lines, tank cleaning, and proper abandonment of borings. The site achieved No Further Action status after nearly two decades of oversight. 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 heating oil release at this property originated from an underground storage tank that was operational by at least the 1960s — confirmed by piping repairs required after an earthquake in that decade — placing the contamination trigger squarely within the era of occurrence-based Commercial General Liability coverage. The documented remediation expenditures, from UST closure and soil removal to long-term regulatory engagement spanning nearly twenty years, are costs tied directly to that pre-1986 release. Historical CGL carriers whose policies were in effect when the tank was in active service may still be obligated to recover those cleanup costs.

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.
