This property has a documented history as a industrial and manufacturing facility going back to 1900. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
The Seattle Lighting Company operated a coal gasification plant at 1177 Elliott Ave. West from the early 1900s through the early 1920s, a tenure confirmed by a 1917 Sanborn map of the area. In fall 1992, Ecology received a report of the historical industrial activity and opened a Standard Cleanup review. The investigation found no site contamination, and Ecology issued 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 Seattle Lighting Company's coal gasification operations predate 1986 by more than six decades, placing them squarely within the era when occurrence-based CGL policies were standard and carried no effective pollution exclusion. Ecology's 1992 report and the Standard Cleanup review that followed generated a formal regulatory record documenting both the scope of the historical industrial use and the investigation costs associated with it. Historical carriers who issued CGL policies to the Seattle Lighting Company during the plant's operating years remain potentially reachable through those pre-1986 instruments, regardless of the No Further Action determination on file.
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.
