Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1966. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This municipal Parks and Recreation Shop operated with at least one underground storage tank, estimated to have been installed around 1966 and removed in 1991 after lubricant-range petroleum contamination was discovered in the surrounding soil and groundwater. Cleanup included overexcavation of petroleum-contaminated soil, off-site disposal, and water management in the excavation area. The site received a No Further Action determination in 2012, confirming the independent cleanup was complete. 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 petroleum release at this site originated from an underground storage tank that was in service for roughly twenty-five years before its removal in 1991 — placing the bulk of its operational life squarely within the pre-1986 window when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The documented remediation costs — tank removal, soil excavation and disposal, water management, and the two-decade path to regulatory closure — are expenditures that historical carriers who covered this facility during its UST operations may still be obligated to reimburse.

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.
