Preliminary Site-Specific Analysis

This property has a documented history as a landfill going back to 1970. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This property sits atop a former construction debris landfill created during the 1970s, when imported demolition debris from I-405 construction and wood chip fill material were placed over existing peat to develop the area. A commercial office building was constructed on the site in 1983. Investigation under the Voluntary Cleanup Program identified the 1970s wood chip fill as the source of contamination, with PCBs, PAHs, and petroleum compounds detected in groundwater. The site has since received a No Further Action determination from Ecology. 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 groundwater contamination at this property — PCBs, PAHs, and petroleum hydrocarbons — traces directly to landfill fill operations conducted throughout the 1970s, more than a decade before 1986. Occurrence-based CGL policies in effect during that fill period carried no effective pollution exclusion in Washington and remain enforceable today. The investigation and remediation costs incurred to bring this former landfill site through the Voluntary Cleanup Program to a No Further Action determination are expenditures that historical carriers who covered the property during the 1970s operations 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

  • Historical insurance policies (pre-1986)

  • Evidence linking cleanup obligation to insured activity

What We Deliver

  • Historical Coverage Chart
  • Trigger Analysis & Property/Policy Nexus

  • Claims Management & Forensic Accounting

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.
