This property has a documented history as a bulk fuel distribution terminal going back to 1916. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This property served as a petroleum bulk storage and distribution site from 1916 through 1976, operated first by Associated Oil and later by Tidewater Oil Company, which maintained gasoline tanks, an office, and oil distribution facilities on the parcel. Three underground storage tanks were removed in the early 1980s, and subsequent investigation confirmed petroleum hydrocarbon contamination in soil and groundwater. A multi-year groundwater monitoring program ran from 1996 to 1998, after which monitoring wells were abandoned and the site received a No Further Action determination, though a restrictive covenant remains in place due to residual petroleum-impacted soil exceeding cleanup levels. 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.
Sixty years of petroleum bulk storage and distribution — from 1916 through 1976 — means this parcel was continuously insured under occurrence-based CGL policies for the entire era before pollution exclusions took hold. The documented remediation costs here — tank removal, soil investigation, three years of groundwater monitoring, and the institutional controls still encumbering the property — trace directly to releases from operations that Associated Oil and Tidewater Oil Company conducted under those policies. Historical carriers on the risk during that six-decade window may bear obligation for costs already incurred and for the residual contamination the restrictive covenant memorializes.
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.
