This property has a documented history as a public works and maintenance facility going back to 1983. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This property was developed as the King County Metro Transit South Operating Base Annex, with predesign and geotechnical investigations beginning in 1983 and site grading and filling completed by 1985. Three underground storage tanks — a 500-gallon engine oil tank and two 10,000-gallon fuel tanks for gasoline and diesel — were installed on the property, and Metro Transit began occupying the facility in 1987. Groundwater investigations identified benzene, petroleum hydrocarbons from diesel and gasoline, and other non-halogenated organics at the site. The property was addressed under the Voluntary Cleanup Program and has achieved No Further Action status. 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.
Development of this transit facility began in 1983 with site investigations and construction activity, placing the facility's establishment squarely within the era when occurrence-based Commercial General Liability policies were standard and carried no effective pollution exclusion. The petroleum contamination documented in groundwater beneath the property — benzene, diesel, and gasoline constituents — required investigation and remediation through the Voluntary Cleanup Program, generating cleanup expenditures tied to operations at a facility whose origins predate 1986. Historical carriers who issued CGL policies during that pre-1986 development and operational window may still be obligated to respond to those 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.
