This property has a documented history as a industrial and manufacturing facility going back to 1949. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
The Carborundum Company constructed this industrial facility in 1949 to manufacture silicon carbide, an abrasive used across a wide range of industrial and commercial applications. Plant operations and on-site waste disposal in ponds continued from the 1950s through 1982, when the facility closed. Environmental investigations conducted in 1984 and 1986 led to Voluntary Cleanup Program remediation that included excavation and removal of approximately 7,000 cubic yards of contaminated soil and debris, thermal desorption treatment of 16,173 tons of contaminated soil, and construction of engineered caps and fills. Institutional controls — restrictive covenants prohibiting potable water extraction and limiting the property to industrial land use — remain in force through an ongoing periodic review process. 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.
Silicon carbide manufacturing and waste disposal operations at this site spanned more than three decades before the plant closed in 1982, placing the contamination's origin squarely in the era before 1986 when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The documented remediation expenditures here — excavation and thermal treatment of tens of thousands of tons of impacted material, engineered capping, and perpetual groundwater monitoring under institutional controls — represent costs tied directly to pre-1986 industrial operations. Historical carriers who issued CGL policies to the Carborundum Company during its operational window may remain obligated to recover those 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.
