This three-acre property operated as the Unocal Bulk Plant 0826 beginning in 1921, with expansion in the 1940s and tank installations in 1949, serving as a petroleum bulk storage and distribution terminal for refined products. Cleanup under the Voluntary Cleanup Program included removal of above-ground storage tanks and at least one underground storage tank in 1992, annual groundwater monitoring from 1994 through 1999, and extensive soil remediation in 2001 that excavated and disposed of over 3,042 tons of contaminated soil. Quarterly groundwater sampling continued through at least 2003, and 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.
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 storage and distribution operations at this site began in 1921 — more than six decades before 1986, when occurrence-based Commercial General Liability policies were replaced by claims-made forms with absolute pollution exclusions. The contamination here, including lead indicative of leaded gasoline handling, traces directly to bulk fuel operations conducted under those earlier policies. A decade of documented remediation costs — tank removals, excavation of over 3,042 tons of soil, and years of groundwater monitoring — represent expenditures that historical carriers who covered Unocal's operations during the pre-1986 window may still be obligated to reimburse.
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.
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.
