This property has a documented history as a property with a heating oil tank predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
This residential property in Camas contains a 675-gallon underground heating oil tank that supplied home heating for decades before the property converted to gas heat — a transition confirmed to have occurred more than 25 years before a December 2016 inspection, placing the tank's last active use no later than 1991. The tank remains in place beneath a porch attached to the house, and soil contamination from a heating oil release has been confirmed at the site. No tank decommissioning or soil remediation has been conducted, and the property is currently awaiting cleanup. 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 heating oil release at this property originated from a tank that was actively in service well before 1986, when occurrence-based policies routinely lacked enforceable pollution exclusions. That pre-1986 operational window is precisely when contamination was accumulating beneath the property — slowly, out of sight, under a residential porch. The cleanup costs now facing the property owner — tank removal, soil investigation, and remediation — represent the kind of environmental loss that historical carriers whose policies covered this property during the tank's active years may be obligated to fund.
