This property has a documented history as a industrial and manufacturing facility going back to 1969. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
This Vancouver property has housed a dental office since 1969, with photographic evidence confirming dentistry operations by at least 1976. Dental amalgam procedures at the site generated elevated concentrations of mercury and silver, which were discharged as industrial waste into the onsite septic system over decades of operation. Washington State Ecology mandated clean-out and remediation of the septic tank in 2010; however, no executed cleanup details are documented in the Site Hazard Assessment, and the site remains in Awaiting Cleanup status. 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.
Mercury and silver contamination at this property originates directly from dental operations that began in 1969 — more than fifteen years before 1986, when occurrence-based Commercial General Liability policies stopped reliably covering pollution claims. The slow, ongoing discharge of heavy-metal amalgam waste into a septic system is precisely the type of continuous release those pre-1986 CGL policies were written to address. Remediation costs ahead — septic system work, site investigation, and whatever cleanup Ecology ultimately requires — may be recoverable from historical carriers whose policies were in force during the decades those discharges occurred.
