Auto Body cleanup site — Restorical Research
Riverside Industrial Park
Seattle, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a auto body / repair shop going back to 1957. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This warehouse and shop property was developed prior to 1929, with buildings erected in 1957 and underground storage tanks installed circa 1964 to support truck repair and maintenance operations that continued through the 1960s and beyond. Cleanup under the Voluntary Cleanup Program included removal of three USTs totaling 3,000 gallons of capacity, one 500-gallon above-ground storage tank, floor drains, and drywells; excavation and thermal desorption of 683 tons (425 cubic yards) of contaminated soil; and pumping of 2,500 gallons of contaminated groundwater. Long-term monitored natural attenuation, supported by nine monitoring wells and groundwater monitoring from 1997 through 2019, brought the site to 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.

The petroleum contamination at this property originates from underground and aboveground storage tanks and floor drainage infrastructure installed and actively used at least two decades before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The remediation record here — UST and AST removals, large-scale soil excavation and thermal treatment, groundwater extraction, and more than twenty years of monitored natural attenuation — documents the kind of sustained cleanup expenditure those pre-1986 policies were written to cover. Historical carriers who issued CGL coverage during the truck repair operations of the 1960s and earlier may remain obligated to recover those 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.
