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.
Camp Silverton is a camp facility operated by Everett Public Schools in Snohomish County. A former fuel tank at the property released petroleum hydrocarbons into soil and groundwater, prompting voluntary action under Washington's Toxics Cleanup Program. Remediation consisted of over-excavation of the former tank, installation of monitoring wells, and sampling activities — work that collectively satisfied regulators and produced 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 fuel tank that caused contamination here was installed and operating well before 1986, the year occurrence-based Commercial General Liability policies began carrying effective pollution exclusions. Petroleum releases from buried tanks are precisely the slow, historical releases those pre-1986 policies were written to cover. The documented remediation costs at this site — tank over-excavation, well installation, and sampling — represent expenditures tied directly to that pre-1986 operational period, and the carriers who issued CGL policies to Everett Public Schools during that window may retain obligations to fund or recover 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.
