Seattle Fire Station 25 has operated at this location since 1969, with two 500-gallon underground storage tanks installed around 1970 to supply diesel fuel for fire apparatus and the station's emergency generator. The USTs were removed in 1999 and replaced with a new 1,100-gallon tank, but residual diesel contamination in soil and groundwater required active remediation from 2016 through 2020 — including a bioremediation pilot study and injection of chemical and biological treatment solutions. Following successful cleanup and well decommissioning, the site received a No Further Action determination in 2020. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.
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.
Diesel contamination at this property originated from underground storage tanks that were installed and operated continuously from 1970 — more than fifteen years before occurrence-based Commercial General Liability policies gave way to claims-made forms with absolute pollution exclusions. The remediation costs incurred here — UST removal, soil excavation, multi-year bioremediation, groundwater treatment, and monitoring-well decommissioning — are the type of documented cleanup expenditures that historical CGL carriers may still be obligated to cover under policies issued during that pre-1986 operational window.
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.
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.
