Preliminary Site-Specific Analysis

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

This property at Boeing Field operated as an aircraft maintenance facility for Flightcraft, Inc., housing a 24,000-square-foot maintenance hangar and office building in a heavily industrial corridor. A 500-gallon waste motor oil underground storage tank — estimated to have been installed around 1966 — was found to be leaking and was decommissioned and removed in March 1991. Cleanup under the Voluntary Cleanup Program included excavation and off-site disposal of 30 cubic yards of contaminated soil, followed by confirmatory soil sampling and quarterly soil and groundwater monitoring that continued through at least 1996. The site has received a No Further Action determination. 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 originated from a waste oil tank that served aircraft maintenance operations for roughly twenty-five years before its removal — placing the onset of the release well before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The documented remediation costs — tank decommissioning, soil excavation and disposal, and years of confirmatory monitoring — are expenditures tied directly to that pre-1986 operational period. Historical carriers who issued CGL policies to the facility's operators during the decades the tank was in service may still be obligated to cover 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.
