This property has a documented history as a dry cleaning facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This property housed Creases Dry Cleaner at 1820 Terry Ave in Seattle, with tetrachloroethene (PCE) and related chlorinated volatile organic compounds identified as the primary contamination source, alongside a 2,700-gallon fuel oil UST in an adjacent apartment building boiler room. Cleanup under the Voluntary Cleanup Program ran from December 2014 through February 2015, encompassing UST removal with 3,500 gallons of associated oily water, excavation of 1,190.69 tons of CVOC-contaminated soil and 1,492.81 tons of petroleum-contaminated soil, and installation of a dewatering system for deeper perched groundwater. Post-remediation sampling confirmed the releases had been addressed and no further groundwater monitoring was required, yielding 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.
PCE contamination from dry cleaning operations — the kind that accumulates gradually in soil and groundwater over years of use — originated at this property from a facility operating prior to 1986, the period when occurrence-based CGL policies were the industry standard. The documented cleanup here removed over 2,600 tons of contaminated soil across two distinct contamination sources — dry cleaning CVOCs and petroleum from a fuel oil UST — representing a quantified remediation cost trail tied directly to those pre-1986 operations. Historical carriers whose policies covered Creases Dry Cleaner and the apartment building during those years may carry obligations proportionate to both liability streams that the 2014–2015 cleanup has now fully documented.
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.
