Preliminary Site-Specific Analysis

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

This property is part of the Yakima Airport, co-owned by the City of Yakima and Yakima County, where municipal maintenance and fire department operations relied on underground fuel storage for decades. Between 1995 and 1998, twenty-eight underground storage tanks were excavated and removed, with contaminated soil remediated onsite through landfarming. A multi-year Remedial Investigation and Feasibility Study conducted from 2009 through 2011 included sixty-six soil borings and extensive groundwater monitoring to evaluate natural attenuation, capping, and institutional controls as remedial alternatives. The site has since 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 airport originated from underground storage tanks that were in service well before 1986 — tank sale records from 1991 and the scale of the UST infrastructure confirm decades of pre-1986 fueling operations. Occurrence-based Commercial General Liability policies issued to the municipal operators during that window carried no effective pollution exclusion under Washington law. The documented remediation expenditures — removal of twenty-eight tanks, soil treatment, a multi-year investigation, groundwater monitoring, and Ecology oversight charges — represent costs that historical carriers who covered the airport's operations may still 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.

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.
