Industrial & Manufacturing cleanup site — Restorical Research
Galvins Flying Service

Preliminary Site-Specific Analysis

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

This property, operated as the Galvin Flying Center, was an aviation maintenance facility that stored waste oil in an underground storage tank. The UST was closed in place in 1999 — concrete walls prevented full removal — with the tank top exposed and petroleum-impacted soil overexcavated during closure; confirmation sampling found TPH concentrations above MTCA cleanup standards (500 ppm at the water table) at one end of the tank. Following UST closure, confirmation soil sampling and groundwater remediation were conducted, culminating in a No Further Action determination from Ecology in 2012. 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 waste oil UST at this aviation maintenance facility was in service well before 1986, the year occurrence-based Commercial General Liability policies began incorporating effective pollution exclusions. Petroleum contamination from UST storage operations of that era is precisely the class of slow, ongoing release that pre-1986 CGL policies were written to cover. The documented remediation costs here — UST closure, impacted soil excavation, groundwater remediation, and multi-year confirmation sampling — represent expenditures potentially recoverable from historical carriers whose policies were in force when the tank and its releases were active.

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)

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.
