This property has a documented history as a gasoline service station going back to 1960. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
The Mabton Mini Mart was constructed in the early 1960s and sold gasoline and diesel fuel through three underground storage tanks — a 2,500-gallon diesel tank, a 5,000-gallon unleaded gasoline tank, and an 8,000-gallon regular gasoline tank. All three USTs were decommissioned and removed in March 1994. Under the Voluntary Cleanup Program, site characterization confirmed petroleum contamination in groundwater; four quarters of monitoring demonstrated that diesel and gasoline concentrations had been remediated below MTCA Method A cleanup levels, and the site 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.
Petroleum contamination at this property originated from underground storage tanks installed in the early 1960s — more than two decades before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion. The documented remediation expenditures — tank removal, site characterization, groundwater monitoring, and cleanup to state standards — were incurred to address releases tied directly to those pre-1986 fueling operations. Historical carriers who issued CGL policies during the 1960s-through-1980s operational window may still be obligated to recover those cleanup 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.
