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 served as the Winthrop National Fish Hatchery, operated by the U.S. Fish and Wildlife Service, with eight underground storage tanks holding gasoline, diesel, and heating oil to support facility operations. The USTs were removed in August 1993, and cleanup under the Standard Cleanup program included over-excavation of contaminated soil from multiple pits, off-site disposal of approximately 150 tons of impacted material, installation of three monitoring wells, and a quarterly groundwater monitoring program spanning more than a year. 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 facility originated from underground storage tanks that supported hatchery operations well before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The documented remediation expenditures — tank removals, multi-pit soil excavation, off-site disposal, and over a year of groundwater monitoring — were incurred to address releases tied directly to those pre-1986 operations. Historical carriers who issued CGL policies during the period these tanks were in service may still be obligated to 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.
