This property has a documented history as a industrial and manufacturing facility going back to 1908. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
The PSE Chehalis Property operated as a manufactured gas plant (MGP) beginning in 1908, producing gas from coal by the carbonization method until 1937 or 1938, then by the water-gas method until the plant ceased operation in 1941. A butane/air storage and delivery infrastructure subsequently occupied the property from 1941 until 1956, with the remaining butane facility demolished between 1971 and 1982. Under the Voluntary Cleanup Program, interim remedial actions in 1994 and 1995 included demolition and removal of the gas holder, a steel tar tank, and concrete vaults, along with the pumping and off-site disposal of approximately 230,000 gallons of oily water and other contaminated materials. The final remedial action consisted of an engineered asphalt cap over residual contaminated soil, combined with long-term groundwater monitoring for benzene and an Environmental Covenant imposing institutional controls; the site has since 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.
Coal tar, carcinogenic polycyclic aromatic hydrocarbons, and benzene contamination at this property trace directly to manufactured gas plant operations that began in 1908 and continued for more than three decades before the plant closed in 1941 — nearly half a century before the industry-wide shift away from occurrence-based Commercial General Liability policies in 1986. Carriers that issued CGL policies to the MGP operators during that pre-1986 window were doing so without an effective pollution exclusion, leaving them potentially obligated for releases tied to those historical operations. The documented remediation expenditures here — demolition of plant structures, off-site disposal of 230,000 gallons of contaminated material, engineered soil capping, and long-term groundwater monitoring — constitute the kind of cost trail that gives property holders standing to pursue those historical carriers.
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.
