This property has a documented history as a industrial and manufacturing facility going back to 1984. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property operated as a surface gravel mine beginning circa 1984, encompassing a crushing plant and asphalt batch plant, with heavy equipment fueled from an aboveground diesel storage tank on site. A diesel spill occurring in the early 1990s during a fuel transfer to that tank contaminated the property; cleanup under the Voluntary Cleanup Program included excavation of 824 tons of impacted soil (with 8,334 cubic yards further planned), recovery of 6,825 gallons of contaminated groundwater, and groundwater monitoring conducted from 2007 through at least 2018. The operator withdrew from the VCP in 2011 due to cost, with proposed bioremediation or landfarming of remaining soil and future monitoring-well decommissioning still outstanding. 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.
The diesel contamination here is directly tied to fueling infrastructure installed for mining operations that commenced in 1984 — within the period when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. Although the spill was identified in the early 1990s, its source was the aboveground storage tank placed in service for those pre-1986 mining activities. The documented remediation expenditures — soil excavation, groundwater recovery, more than a decade of monitoring, and ongoing cleanup yet to be completed — are costs that historical carriers whose policies covered the 1984–1986 operational window may be obligated both to recover and to fund going forward.
