This property has a documented history as a industrial and manufacturing facility going back to 1960. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property hosted a wood preserving operation from approximately the 1960s through the 1980s, using a pentachlorophenol (PCP) dip tank to treat wood products. Initial site investigations in 1987 and 1988 confirmed contamination from these historical operations, and cleanup activities under the Voluntary Cleanup Program have included soil excavation, landfarming, and offsite disposal of contaminated soils. Multi-year monitoring, environmental covenants, and additional soil and groundwater testing remain ongoing. 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.
Pentachlorophenol contamination at this site originated from industrial wood treatment operations that ran for roughly two decades before 1986, squarely within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The remediation costs already incurred — excavation, landfarming, offsite disposal, and long-term monitoring — along with the additional cleanup and testing still ahead, represent expenditures that historical carriers who covered the wood treatment operation may be obligated both to reimburse and to fund going forward.
