This property has a documented history as a industrial and manufacturing facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
Colville Post & Poles operated a wood-treating facility at this Hwy 395 property from the late 1950s through January 2005, processing wood products with a heated solution of approximately 95% diesel and 5% pentachlorophenol (PCP). Remediation has been underway since 1989: two phases of soil excavation have removed 6,991 tons of impacted material, product recovery was conducted from on-site wells, the facility building was demolished, and a soil cap was placed and maintained. EPA undertook specific response actions in 2005–2006, and Ecology has been involved since 2015; proposed future remediation — spanning soil washing, thermal desorption, and multiple groundwater treatment alternatives — carries an estimated cost of $26.3 million. 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 PCP and diesel contamination at this site originated from wood-treating operations that began in the late 1950s and continued for nearly five decades before the facility closed — a span during which pre-1986 CGL policies issued to the operators were in effect and had no effective pollution exclusion for these types of slow, ongoing industrial releases. The excavation of nearly 7,000 tons of impacted soil, product recovery, demolition, and capping already completed since 1989 represent documented remediation expenditures that historical carriers may be obligated to recover. With $26.3 million in projected costs still ahead under Ecology's Standard Cleanup program, the potential insurance obligation covers both what has already been spent and what remains to be funded.
Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.
