This property has a documented history as a gasoline service station going back to 1993. Historical insurance policies issued during operations at this property and through 1986 could recover the cleanup costs already paid.
This property at 710 S Grady Way in Renton has operated as an ARCO-branded gasoline service station and convenience store since at least 1993, with four underground storage tanks and six fueling dispensers on site. Petroleum contamination — including gasoline-range hydrocarbons, benzene, ethylbenzene, toluene, xylenes, and lead — was discovered in soil and groundwater during retail upgrade activities in 2004–2005. Cleanup under the Voluntary Cleanup Program included excavation and off-site disposal of approximately 470 tons of contaminated soil, annual groundwater monitoring since 2005, and ongoing natural attenuation. The site has received 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.
While property records document gasoline operations beginning in 1993, circumstantial indicators suggest the site may have supported fueling activity before that date: lead detected in groundwater is characteristic of the leaded-gasoline era that ended in the 1980s, and the 2005 tank replacement is consistent with tanks originally installed well before 1993. If pre-1986 operations are substantiated, occurrence-based CGL policies issued during that earlier window — which carried no effective pollution exclusion in Washington — could obligate historical carriers to cover the remediation costs already incurred at this property.
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.
