This property has a documented history as a industrial and manufacturing facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This right-of-way in Ellensburg was contaminated by heavy oil traced to a Burlington Northern Railroad roundhouse — a locomotive maintenance and servicing facility — located adjacent to the site. A 1991 site assessment found the oil spill could have been present for more than 40 years, placing the likely release at or before 1951. Cleanup activities included excavation and removal of petroleum-contaminated soil, remediation of a 2,000-gallon underground storage tank, installation of a polyethylene membrane barrier, and proposed groundwater dewatering with discharge to the Ellensburg sewage treatment plant; the project concluded with a No Further Action determination in 2021. 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 heavy oil contamination at this site originated from railroad operations that pre-date 1986 by decades, with investigators placing the release at or before 1951. Occurrence-based Commercial General Liability policies issued to the railroad or its predecessors during that pre-1986 operational window had no effective pollution exclusion and may remain enforceable today. The documented costs of soil removal, tank remediation, barrier installation, and long-term monitoring represent expenditures that historical carriers whose policies were in effect at the time of release may be obligated to recover.
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.
