This property has a documented history as a bulk fuel distribution terminal predating 1986. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
The Former Pioneer Quarry property in Gorst served a dual function: a gravel quarry and a bulk petroleum distribution point, with a former oil distributor, an above-ground oil stand, and a suspect 300-gallon diesel/gas underground storage tank documented on site. Total petroleum hydrocarbons — both diesel and gasoline fractions — contaminated soil as a result of releases from that petroleum storage infrastructure. Cleanup under the Voluntary Cleanup Program involved over-excavation of TPH-affected soil, after which Washington State Ecology determined no further remedial action was necessary and terminated the VCP agreement. 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 petroleum contamination here originated from bulk storage and distribution operations — an oil distributor, above-ground tank, and underground storage tank — that were in place well before 1986, when occurrence-based Commercial General Liability policies were still the industry standard and carried no effective pollution exclusion. A documented release from pre-1986 petroleum infrastructure is precisely the fact pattern those policies were written to address. Historical carriers who issued CGL policies to the operators of the oil distribution activities during that period may still be obligated to recover the soil remediation costs the site incurred.
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.
